Part I

Item 1. Business

Overview

Since its inception, AON has offered a progressive model of physician-led, community-based oncology management. AON preserves and elevates community oncology by helping its physicians navigate the complex healthcare landscape, providing them an efficient platform to work autonomously and thrive, and most importantly, improving the quality of patient care that is being delivered. We are an alliance of physicians and veteran healthcare leaders partnering to ensure the long-term success and viability of oncology diagnosis and treatment in community-based settings. As of December 31, 2023, AON’s platform includes 32 practices across 19 states and the District of Columbia (“Network Practices”). Our robust platform provides oncology practices with comprehensive support, access to revenue-diversifying adjacent services and practice management expertise to empower physicians to make cancer care better for every patient.

Our mission is to provide the best cancer care that is affordable and close to where patients live and work. We believe the key to accessible and equitable healthcare lies in the strength of community healthcare practices and we are committed to closing the gap in cancer care to ensure every patient has access to the optimal care needed to help in their fight against cancer. To accomplish this, we have practices in some of the most densely populated cities as well as rural areas where medical resources are scarce. We deliver cancer care innovation by bringing new treatments to the forum and also by ensuring the access to the necessary adjacent services to provide comprehensive quality cancer care and preserving the delivery of personalized cancer care in the community oncology setting.

Through access to care-enhancing patient services such as a centralized specialty pharmacy, wide ranging clinical lab and pathology, a fully integrated technology platform anchored by an oncology-specific electronic medical record system, as well as a care management team and a variety of financial assistance programs, our patients receive expert cancer care at each of our clinics.

We provide patients a variety of services to enhance patient care throughout the healthcare journey: high-quality and timely laboratory services for routine and specialized testing; in-house professional and technical pathology providing complete, accurate and timely pathology reports; in-house specialty pharmacy with patient education, financial assistance, and 24/7 patient assistance; and care management support services including nutrition guidance.

As the future of healthcare continues to transition from volume to value, we are at the forefront of this initiative by ensuring care quality over care quantity and adopting a patient-first mentality. Through an integrated system of seamless communication, coordination and patient care for better health outcomes, AON practices benefit from decreased expenditures through the implementation of centralized administrative services, processes, and technologies designed to support effective decision-making such as optimal pricing on drugs and medical supplies. Our patients benefit through our 24/7 clinical care support leading to a reduction in unnecessary emergency room visits and admissions and enhanced care quality. Ultimately, the payors benefit from more efficient delivery of high-quality, comprehensive services comparable to any hospital system at a lower cost point.

Though our network spans the country, its clinicians are interconnected and focused on driving change not just at their local clinics, but throughout our network. Our Network Practices unite in collaboration through a physician advisory board, which acts as a liaison between AON management and our Network Practices so that we remain apprised of issues and opinions concerning our Network Practices. In addition, our Network Practices also remain at the forefront of new discoveries and findings by expanding and improving cancer treatment options for every patient through a pharmacy and therapeutics committee that continuously updates its formulary in real time as advanced therapeutics come to market and through participating in clinical research to ensure we remain on the cutting edge of cancer protocols. Patients benefit from convenient access to clinical trials that we participate in without the need to travel to large cities or tertiary cancer care facilities, and personalized care by matching a patient’s cancer to a tailored therapy using molecular profiling.

We have made significant investment in a resilient, integrated technology platform to support the practices which includes a fully-integrated electronic health record and a robust decision support tool and analytics engine. Our development of compliance materials ensures consistency and optimal patient experiences and meets or exceeds the Office of Inspector General (“OIG”) guidelines.

Table of Contents

We believe that our position in the market and focus on elevating the state of oncology care with our affiliated providers bodes well for future growth. Our proprietary technology platform supports this growth and enables the Network Practices to standardize and deliver consistent care at scale. We believe that our model will support growth into new markets and allow us to continue to service more patients across the United States.

Market Overview

Our business is focused on caring for adult and senior populations with medical oncology and related care needs, including members of Medicare Advantage (“MA”) plan run by private insurance companies on behalf of the Centers for Medicare and Medicaid Services, or CMS, as well as traditional Fee-For-Service (“FFS”) Medicare, Medicaid, other government healthcare programs and commercial insurance populations.

As of December 31, 2023, we were active across 32 practices in 19 states and the District of Columbia. We also operate a triple-accredited specialty pharmacy and a state of the art clinical laboratory. According to the Community Oncology Services Global Market Report 2023, the global community oncology services market size is expected to grow to $81.33 billion in 2027 at a compound annual growth rate (“CAGR”) of 10.9%. Furthermore, according to the BCC Research Global Oncology Pharmaceuticals Market Report, the oncology pharmaceuticals market, which is also a significant market of AON’s services, is currently a $177 billion industry and is expected to grow to $314 billion by 2026. This expanding market provides us with a substantial opportunity to grow in both our legacy, existing markets, as well as in our new expansion geographies.

Our Care Model

Since our founding, we have offered a progressive model of physician-led, community-based oncology management. It preserves and elevates community oncology by helping our physicians navigate the complex healthcare landscape, providing them an efficient platform to work autonomously and thrive, and most importantly, improving the quality of patient care that is being delivered. Our care model is focused on delivering personalized, evidenced-based care consistently and at scale. We seek to deliver better patient outcomes for lower costs, and to care for more of our payors’ patient populations. Our care model is team-focused and values-driven and promotes a culture of loyalty and trust from providers and staff, leading to strong clinical outcomes.

● Continuously Supporting the Patient — Deliver results by providing compassionate oncology and hematology services with continued focus on the patient.

● Always Do the Right Thing — Committed to personal excellence, accountability, and integrity, abiding by the highest regulatory standards, performing in the most ethical manner, and taking responsibility for actions.

● Respectfully Engage — Foster positive relationships, encourage diversity of thought, and promote trust among teams and customers; encouraging healthy debate and respect for the thoughts and opinions of others; believing that talent, skills, and expertise are most important.

● Exceed Expectations — Striving to provide excellence in all things; creating a standard of caring that goes above and beyond while embracing change in support of continuous improvement for patients.

Our Network Physician Practices

Table of Contents

We operate our physician practices through management service agreements (“MSAs”) between American Oncology Management Company, LLC (“AOMC”), and American Oncology Partners, P.A. (“AON Partners”), and American Partners of Maryland, P.A. (“Partners of Maryland”). AOMC is a wholly owned subsidiary of the Company while AON Partners and Partners of Maryland are physician owned.

Under our MSAs, we have agreed to serve, on an exclusive basis, as manager and administrator of each our practice’s non-medical functions while healthcare services and items provided to patients are provided by physicians and other licensed healthcare providers employed by or under contract with a practice. Under the MSAs, the responsibilities of AOMC include, but are not limited to, negotiating provider and payor contracts, employment and compensation decisions, billing and collections, furnishing all supplies and equipment necessary for the respective practice’s operations as well as, necessary real estate, contracting on behalf of AON Partners and Partners of Maryland, entering into leases, holding a power of attorney to perform the above activities, preparing, maintaining and administering all accounting records (including financial reporting), expense payment, and maintenance of all information systems/software. Furthermore, the MSAs provide that AON Partners and Partners of Maryland have sole discretionary authority on decisions with respect to medical practice and shall be based on their professional judgment and in the best interests of patients. The MSAs also provide that AOMC will not interfere with AON Partners’ and Partners of Maryland’s decisions with respect to the supervision, selection, terms, conditions or obligations of their physicians and healthcare professionals. In addition, the MSAs provide that services provided by AOMC will comply with applicable federal and state requirements, as well as any accreditation and certification requirements applicable to medical practices.

We are paid a management fee to compensate AOMC for the services provided. The management fee has fixed and variable components and is negotiated and agreed upon on an annual basis by AOMC and AON Partners or Partners of Maryland, respectively. The fixed amount of the management fee to be agreed upon is based primarily on expenses incurred by AOMC in connection with providing management and administrative services to each of AON Partners’ and Partners of Maryland’s medical practices. The variable component of the management fee is based primarily on the volume of collections by AON Partners and Partners of Maryland and their respective profitability. The variable component of the management fee does not exceed 10% of the collections of our practices. In accordance with relevant accounting guidance, each of AON Partners and Partners of Maryland is determined to be a variable interest entity, or VIE, of AON because AON has the ability under the MSAs to direct the activities (except for clinical decisions) that most affect the economic performance and profitability of AON Partners and Partners of Maryland. Our MSAs with AON Partners or Partners of Maryland have five-year terms that automatically renew for successive five-year terms, unless terminated upon mutual agreement of the parties or unilaterally by a party following a material breach or commencement of bankruptcy or liquidation events by the other party, or a governmental or judicial termination order against a party.

Our Value Proposition

We believe we have developed a compelling value proposition for each of our patients, providers, and payors. We seek to provide high quality and lower cost care delivery through the following capabilities:

Patient

● Quality providers, continuous clinical improvements, and ancillary services such as clinical laboratory, professional and technical pathology services, oral oncolytic pharmacy, care management, and access to clinical trials set a high standard of patient care.

● Optimization of centralized administrative services allows providers the opportunity to maximize time serving patients.

● In addition to traditional oncology care, a focus on addressing patients’ mental and spiritual health.

● Delivery of true Value Base Care (“VBC”) through participation in alternative payment models such as CMS’ Oncology Care Model.

Providers

● Strong culture, based on a prominent clinical reputation, and attractive physician ownership model enable us to attract and retain the best providers in a competitive market.

● Proven practice management expertise, driving practice growth by providing outstanding administrative support including managed care services, drug procurement, and revenue cycle management, as well as a proprietary playbook on driving same store growth of new patients for AON practices.

Table of Contents

● Access to new revenue streams through centralized ancillaries such as clinical lab, pathology, and oral oncolytic pharmacy enables practice growth.

● Favorable drug pricing through preferred vendor agreement with a major pharmaceutical distributor.

● Differentiated, provider-centric culture attracts the industry’s leading providers.

96% Physician Quality Score according to CMMI (Center of Medicare and Medicaid Innovation).

Payors

● Experienced and knowledgeable centralized Payor Strategy & Relations team coordinates with practices to maintain close relationships with all payors across the AON platform.

● Robust suite of solutions offered to practices driving cost savings for payors, addressing three cost drivers: 1) Variable use of drugs and diagnostics during treatment; 2) Deterioration of patient health between treatments; and 3) Ineffective interventions near the end of life.

● Optimized management solutions generating operational efficiencies and cost savings shared with payors.

We strive to add value by consistently performing these activities effectively. The goal is a lower cost of care for the same or better clinical outcomes while providing a superior patient experience.

Growth Strategy and Opportunities

To date, we have achieved rapid growth through acquisition of existing practices and through organic growth of these practices after acquisition. Revenue has grown at a roughly 42% CAGR from 2019 to 2023.

Our practice footprint as of December 31, 2023, spanned 19 states and the District of Columbia with 32 total practices.

12034_AON_Current-Locations_Mainland_Map_230601_FINAL.jpg

We anticipate adding more managed practices in the future across our markets through acquisitions and through organic growth within existing practices.

Our go-to-market strategy focuses on demographic trends, secular tailwinds, and fragmented community-based oncology practices facing pricing pressures, as follows:

● According to BCC Research, oncology medicine spending is forecasted to grow at a 12% long-term CAGR.

Table of Contents

● Recent treatments tailored to the specific genomic sequence of each patient’s tumor have continued to drive growth in the oncology market.

● The number of cancer cases through 2040 is expected to grow five times faster than the population growth per the Journal of Clinical Oncology.

● The oncology service market is vast and extremely fragmented in the U.S. Of the over 12,000 oncologists in the country, approximately 76% work in practices that employ between 1 – 5 oncologists.

We are well-positioned to capitalize on this growth opportunity given our hands-on, “Patient-First” model, practice revenue diversification offerings such as our in-house pathology lab, and our specialty pharmacy which can dispense over 96% of the oral oncolytics available in the market today. We have multiple strategies we believe can achieve long-term growth.

● Significant Growth Embedded Within Existing Business: Our existing physician base will continue to grow as AON drive deeper penetration of adjacent services and our physician recruitment team recruits new physicians to practices that are already part of the AON network. We have invested heavily in corporate infrastructure over the past two years, which should lead to significant operating leverage.

● New Service Line Growth: New service lines will drive growth from our existing physician base and attract new physicians to the network. A sample of such new services that have been recently implemented are as follows:

● In December 2022, we launched our new AON Pharmacy MSA model that will offer potential AON practices access to pharmaceutical management and a la carte services.

● We are initiating new revenue streams developed from clinical informatics and data licensing subscriptions.

● Implementing new CMS-approved patient services including Principal Care Management (“PCM”), Transitional Care Management (“TCM”), and Chronic Care Management (“CCM”).

● Participation in alternative payment models developed by CMMI and third-party payors.

● M&A Opportunities: We plan to pursue accelerated growth through acquisition with a more aggressive approach towards M&A. Access to the public markets allows us to pursue a broader M&A strategy and opening up the universe of potential targets. In addition, our more robust service offerings and flexibility in deal structuring will allow for acceleration of our M&A efforts.

● Expansion of research initiatives: We believe today’s research is tomorrow’s standard of care, accordingly, AON plans to expand our national research platform. Access to cutting edge clinical trials within the community setting will be critical to oncology research and drug development and AON practices have the best opportunity to offer patients access to such trials. We offer centralized administrative resources and innovative technology solutions that allows for the timely and efficient expansion in numbers of research investigators and clinical locations throughout the US. With a significant investment in our standardized technology platform, AON maintains the ability to collaborate closely with trial sponsors in order to timely identify patients for clinical trial accrual across our network.

Contracting

Governmental programs, such as Medicare and Medicaid, are collectively the largest payors for our affiliated practices and includes Managed Medicare and Medicaid programs whereby Medicare and Medicaid contract with third-party payors to administer health plans for their beneficiaries. Under such programs, physicians are reimbursed at negotiated rates rather than the Medicare fee schedule and the payor is a third-party, rather than Medicare and Medicaid itself.

Medicare reimbursement for physician services is based on a fee schedule, which establishes payment for a given service, in relation to actual resources used in providing the service, through the application of relative value units. The resources used are converted into a dollar amount of reimbursement through a conversion factor, which is updated annually by CMS, based on a formula.

Also, Medicare reimburses providers for oncology pharmaceuticals administered in our clinics based on the average sales price (“ASP”) for drugs plus a fixed percentage (adjusted for sequestration). Our ability to manage pharmaceutical acquisition costs and concentration of our purchases with a limited number of manufacturers is critical to our success. Nearly all of our pharmaceutical pricing advantage relative to other suppliers is derived from a limited number of drugs. Implementation of ASP-based reimbursement has reduced the amount of differential pricing that is available to us from pharmaceutical manufacturers, which is one of our key competitive strengths.

In addition to traditional FFS arrangements, we continue to explore several other forms of alternative payment models including value-based arrangements. Although many of these arrangements continue to be based on an FFS-based methodology, our affiliated providers are eligible to earn additional bonuses based on their ability to achieve oncology-

Table of Contents

specific clinical and other quality of care-based benchmarks as well as financial rewards often based on total cost of care. While these alternative value-based arrangements may not produce as much initial revenue, we believe this flexibility in contracting models will allow us to speed our expansion into new markets while preserving the value-based economics that are critical for our business’ growth and success.

Payor Relationships

We are attractive to physician practices because of our ability to efficiently manage payor relationships for our Network Practices. As is the case with many healthcare providers, our Network Practices seek payment for their services from a limited number of payors. We generally manage our Network Practices’ payor contracts on a state-by-state basis, entering into a separate contract in each state with the local affiliate of the relevant payor such that no one local payor contract accounts for a majority of our collective revenue. Our centralized Payor Strategy & Relations team coordinates with practices and fosters close relationships with all payors across the AON platform. Our solutions offer unique cost savings opportunities to payors, and our optimized revenue cycle management function generates operation efficiencies and cost savings that are shared with payors. We believe these factors make our practices attractive to payors. Our Network Practices have long-term contracts with many payors including some of the biggest and most respected names in healthcare, including Anthem and United Healthcare. Generally, the contracts with our payors are entered into on substantially consistent terms. These terms include the period of performance, reimbursement rates and termination clauses that are standard in the industry. For example, typically, many of our contracts are terminable for convenience by either the payor or us after a notice period has passed. Many of our payor contracts include cure periods for certain breaches, during which time we may attempt to resolve any issues that would trigger a payor’s ability to terminate the contract. Typically, contracts may be terminated immediately by the payor if we lose applicable licenses, go bankrupt, lose our liability insurance, become insolvent, file for bankruptcy or receive an exclusion, suspension or debarment from state or federal government authorities. We consider our relationships with our payors to be very strong.

Practice Structure, Staffing and Network Design

We have a standard clinic design and approach to staffing that we continually improve and refine.

Managed clinics average 6,200 square feet and typically offer services from up to 30 providers (physicians and advanced practice providers) per clinic. We have flexibility around clinic size to allow us to establish smaller clinics and part time staffing in areas where needed to ensure the Network Practices can meet patient needs under existing payor contracts. We group our managed clinics by geography into regions. We have operations teams managing our markets and regions allowing us to drive performance and scale efficiently.

Competition

The U.S. healthcare industry is highly competitive. We compete directly with national, regional, and local providers of healthcare for patients and physicians. Our primary competitors are traditional community oncology physician practices, local and national health systems and national oncology management service organizations such as US Oncology Network, Inc., and OneOncology, Inc. Similar to the Company, US Oncology Network, Inc. and OneOncology, Inc. each offers a nationwide oncology management platform that offers diagnostics, specialty pharmacies and clinical laboratories; however, we differentiate ourselves from these competitors in our management model. We give our network physicians a high level of autonomy with respect to their practice after joining our network as AON employed physicians. We believe this structure differentiates us from our competitors. Some of our competitors may have greater recognition and be more established in their respective communities than we are and may have greater financial and other resources than we have. Competing oncology care providers may also offer larger facilities or different programs or services than our Network Practices do, which, combined with the foregoing factors, may result in our competitors being more attractive to our current patients, potential patients, and referral sources. We believe the principal competitive factors for serving the healthcare market include patient experience, quality of care, health outcomes, total cost of care, brand identity and trust in that brand. We believe we compete favorably on all these factors within the markets we serve.

Government Regulation

Regulatory Licensing, Accreditation and Certification

Participants in the healthcare industry are required to comply with extensive government regulation at the federal, state and local levels. If we fail to comply with applicable laws and regulations, we may be subject to criminal penalties

Table of Contents

and civil sanctions, our providers could lose their licenses and we could lose our ability to participate in Medicare, Medicaid, and other government programs. These legal and regulatory standards address, among other issues, licensure, certification, and enrollment with government programs; the necessity and adequacy of medical care; quality of medical equipment and services; qualifications of medical and support personnel; operating policies and procedures; billing and coding for services; handling overpayments; classifications of levels of care provided; relationships with referral sources and referral recipients; maintenance of adequate records; rate-setting; building codes; environmental protection; privacy and security; interoperability and refraining from information blocking; debt collection; balance billing and billing for out-of-network services; and communications with patients and consumers.

Our clinics are subject to periodic inspection by federal, state, and local authorities to determine their compliance with applicable regulations and requirements necessary for licensing and certification. All of our clinics and providers are licensed under appropriate state laws and are qualified to participate in Medicare and Medicaid programs. Government regulations may change. If that happens, we may have to make changes to our facilities, equipment, personnel, and services so that our practices remain certified and qualified to participate in these programs. We believe that our practices are in substantial compliance with current federal, state, and local regulations and standards. We cannot be certain that governmental officials responsible for enforcing these laws or whistleblowers will not assert that we are in violation of them or that such statutes or regulations will be interpreted by the courts in a manner consistent with our interpretation.

State Corporate Practice of Medicine and Fee-Splitting Laws

Some states, including states where we operate, prohibit unlicensed persons or business entities, including corporations, from employing physicians. These prohibitions are generally referred to as prohibitions against the “corporate practice of medicine,” and their primary objective is to protect physicians’ independent medical judgment from the influence of corporate profit motives. Corporate practice of medicine doctrines vary from state to state, and can be found in a mix of state laws and regulations, case law and state attorney general opinions. But in virtually all (if not all) states, physicians are generally permitted to practice medicine through professional corporations or professional limited liability companies that restrict their ownership solely to licensed physicians.

Some states, including states where we operate, also have adopted laws that prohibit “fee-splitting” arrangements with physicians and unlicensed persons or business entities. Possible sanctions for violations of corporate practice of medicine and fee-splitting restrictions include loss of a physician’s license, civil and criminal penalties, and rescission of business arrangements. These laws vary from state to state, are often vague and in some cases, have seldom been interpreted by the courts or regulatory agencies.

In order to comply with these various state laws and doctrines, a non-licensed entity that enters into a business relationship with a physician practice will often use a management services model. In this structure, a professional corporation or limited liability company is formed with 100% physician ownership. Such physician-owned entity contracts with a management services organization to furnish management and other services to the professional entity in consideration of a commercially reasonable, fair market value fee. The physician-owned entity employs or contracts with all of the practice’s licensed clinical personnel, such as physicians and advanced practice practitioners. The management services organization employs all of the non-clinical personnel who will furnish administrative and business services to the physician-owned entity, such as financial management, billing and collection, human resources, management of office space, etc. The physician-owned entity typically pays for all clinical compensation, benefits and malpractice insurance expenses of the practice from the professional revenues it generates. The management services organization, on the other hand, will incur all other expenses for the practices, which it will pay using its management fee. The end result is that the physician-owned entity maintains control over the clinical aspects of the practice — maintaining independent professional judgment with respect to patient care — and the management services organization manages the physician-owned entity’s back office functions. AON employs such an accepted model to comply with state regulations relating corporate practice and fee splitting laws in the states where AON operates.

Healthcare Fraud and Abuse Laws

We are subject to a number of federal and state healthcare regulatory laws that restrict certain business practices in the healthcare industry. These laws include, but are not limited to, federal and state anti-kickback, self-referral, false claims, and other healthcare fraud and abuse laws.

The federal Anti-Kickback Statute, or AKS, which prohibits the knowing and willful offer, payment, solicitation or receipt of any bribe, kickback, rebate, or other remuneration for referring an individual, in return for ordering,

leasing, purchasing, or recommending or arranging for or to induce the referral of an individual or the ordering, purchasing, or leasing of items or services covered, in whole or in part, by any federal healthcare program, such as Medicare and Medicaid. Courts have interpreted this statute broadly and held that there is a violation of the AKS if just one purpose of the remuneration is to generate referrals, even if there are other lawful purposes. Furthermore, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it to have committed a violation.

The federal physician self-referral law, the Stark Law, which, subject to limited exceptions, prohibits physicians from referring Medicare or Medicaid patients to an entity for the provision of certain designated health services, or DHS if the physician or a member of such physician’s immediate family has a direct or indirect financial relationship (including an ownership interest or a compensation arrangement) with the entity, and prohibits the entity from billing Medicare or Medicaid for such DHS.

The federal False Claims Act, or FCA, which imposes civil and criminal liability on individuals or entities that knowingly submit false or fraudulent claims for payment to the government or knowingly make, or cause to be made, a false statement in order to have a false claim paid, including qui tam or whistleblower suits. There are many potential bases for liability under the FCA. The government has used the FCA to prosecute Medicare and other government healthcare program fraud such as coding errors, billing for services not provided, and providing care that is not medically necessary or that is substandard in quality. In addition, the government may assert that a claim including items or services resulting from a violation of the AKS or Stark Law constitutes a false or fraudulent claim for purposes of the FCA.

The Civil Monetary Penalties Law, which prohibits, among other things, an individual or entity from offering remuneration to a federal healthcare program beneficiary that the individual or entity knows or should know is likely to influence the beneficiary to order or receive healthcare items or services from a particular provider. We may also be subject to civil monetary penalties and other sanctions under the statute if we or our Network Practices hire or contract with any individuals or entities that are or become excluded from government healthcare programs, for the provision of items or services for which payment may be made under such programs.

The Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) also established federal criminal statutes that prohibit, among other things, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including private third-party payors, and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Similar to the AKS, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.

Several states in which we operate have also adopted similar fraud and abuse laws as described above. The scope of these laws and the interpretations of them vary from state to state and are enforced by state courts and regulatory authorities, each with broad discretion. Some state fraud and abuse laws apply to items or services reimbursed by any payor, including patients and commercial insurers, not just those reimbursed by a federally funded healthcare program.

The laws and regulations in these areas are complex, changing and often subject to varying interpretations. As a result, there is no guarantee that a government authority will find that we or our Network Practices are in compliance with all such laws and regulations that apply to our business. Further, because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of the business activities undertaken by us or our Network Practices could be subject to challenge under one or more of these laws, including, without limitation, patient assistance programs that waive or reduce the patient’s obligation to pay copayments, coinsurance or deductible amounts owed for the services provided to them if they meet certain financial need criteria. If our or our Network Practices’ operations are found to be in violation of any of such laws or any other governmental regulations that apply, we may be subject to significant penalties, including, without limitation, administrative, civil, and criminal penalties, damages, fines, disgorgement, the curtailment or restructuring of operations, integrity oversight and reporting obligations, contractual damages, exclusion from participation in federal and state healthcare programs and imprisonment. In addition, any action against us or our Network Practices for violation of these laws or regulations, even if successfully defended against it, could cause us to incur significant legal expenses, divert our management’s attention from the operation of our business and result in adverse publicity, or otherwise experience a material adverse impact on our business, results of operations, financial condition, cash flows, reputation as a result.

Healthcare Reform

Table of Contents

Our revenue is dependent on the healthcare industry and could be affected by changes in healthcare spending, reimbursement, and policy. By way of example, the Affordable Care Act (ACA), which was enacted in 2010, made major changes in how healthcare is delivered and reimbursed, and it increased access to health insurance benefits to the uninsured and underinsured populations of the United States. Since its enactment, there have been judicial, executive, and Congressional challenges to certain aspects of the ACA.

On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA. Prior to the Supreme Court’s decision, President Biden issued an executive order initiating a special enrollment period from February 15, 2021 through August 15, 2021 for purposes of obtaining health insurance coverage through the ACA marketplace. The executive order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare. It is unclear how healthcare reform measures enacted by Congress or implemented by the Biden administration, if any, will impact our business.

Other legislative changes have been proposed and adopted since the ACA was enacted. These changes include aggregate reductions to Medicare payments to providers of 2% per fiscal year, which began in 2013 and will remain in effect through 2030, with the exception of a temporary suspension from May 1, 2020 through March 31, 2022. Under current legislation, the actual reduction in Medicare payments varies from 1% from April 1, 2022 to June 30, 2022, to up to 3% in the final fiscal year of this sequester, unless additional Congressional action is taken. In January 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to several types of providers, including hospitals, imaging centers and cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. New laws may result in additional reductions in Medicare and other healthcare funding, which may materially adversely affect consumer demand and affordability for our products and services and, accordingly, the results of our financial operations. Additional changes that may affect our business include the expansion of new programs such as Medicare payment for performance initiatives for physicians under the Medicare Access and CHIP Reauthorization Act of 2015, or MACRA, which first affected physician payment in 2019. At this time, it is unclear how the introduction of the Medicare quality payment program will impact overall physician reimbursement. The Inflation Reduction Act of 2022, or IRA, signed into law on August 16, 2022, also contains a number of provisions designed to limit or reduce drug prices under the Medicare program, reduce beneficiary out-of-pocket spending under Medicare’s prescription drug benefit, and expand subsidies for individuals to obtain private health insurance under the ACA. While these provisions of the IRA do not apply directly to healthcare providers like our Network Practices, we are continuing to evaluate the potential impact, if any, that the IRA may have on our business.

The 21st Century Cures Act (the “Cures Act”), which was signed into law in December 2016, includes provisions related to data interoperability, information blocking and patient access. In May 2020, the HHS Office of the National Coordinator for Health Information Technology, or ONC, and CMS published the Cures Act final rule, which was intended to clarify provisions of the Cures Act regarding interoperability and information blocking, and include, among other things, requirements surrounding information blocking, changes to ONC’s health IT certification program and requirements that CMS-regulated payors make relevant claims/care data and provider directory information available through standardized patient access and provider directory application programming interfaces, or APIs, that connect to provider electronic health record systems, or EHRs. The final rule will transform the way in which healthcare providers, health IT developers, health information exchanges/health information networks, or HIEs/HINs, and health plans share patient information, and create significant requirements for healthcare industry participants. For example, the final rule, which went into effect on April 5, 2021, prohibits healthcare providers, health IT developers of certified health IT, and HIEs/HINs from engaging in practices that are likely to interfere with, prevent, materially discourage, or otherwise inhibit the access, exchange, or use of electronic health information, or EHI, also known as “information blocking.” To further support access and exchange of EHI, the final rule identifies eight “reasonable and necessary activities” as exceptions to information blocking activities, as long as specific conditions are met. Any failure to comply with these rules could have a material adverse effect on our business, results of operations and financial condition.

There is also uncertainty regarding the potential impact of other reform efforts at the federal and state levels. For example, some members of Congress have proposed measures that would expand government- sponsored coverage, including proposals to expand coverage of federally-funded insurance programs as an alternative to private insurance or establish a single-payer system (such reforms often referred to as “Medicare for All”). Some states have implemented or are considering measures such as individual health insurance mandates and public health insurance options. Other initiatives and proposals, including those aimed at price transparency and out-of-network charges, may impact prices and the relationships between health care providers, insurers and patients. For example, the No Surprises Act requires providers

Table of Contents

to send an insured patient’s health plan a good faith estimate of expected charges, including billing and diagnostic codes, prior to when the patient is scheduled to receive the item or service.

HIPAA Administrative Simplification and Privacy and Security Requirements

The Health Insurance Portability and Accountability Act of 1996, or HIPAA, requires the use of uniform electronic data transmission standards for healthcare claims and payment transactions submitted or received electronically. These provisions are intended to encourage electronic commerce in the healthcare industry. U.S. Department of Health and Human Services Agency (“HHS”) has established electronic data transmission standards and code sets that all healthcare providers must use when submitting or receiving certain healthcare transactions electronically and has issued operating rules to promote uniformity in the implementation of each standardized electronic transaction. HIPAA also requires that each provider use a National Provider Identifier.

As required by HIPAA, HHS has issued privacy and security regulations that extensively regulate the use and disclosure of individually identifiable health-related information and require covered entities, including health plans and most healthcare providers, to implement administrative, physical and technical practices to protect the security of individually identifiable health information that is electronically maintained or transmitted. Business associates (entities that handle protected health information for or on behalf of covered entities) are subject to direct liability for violation of applicable provisions of the regulations. In addition, a covered entity may be subject to penalties as a result of a business associate violating HIPAA, if the business associate is found to be an agent of the covered entity. We have developed and utilize a HIPAA compliance plan as part of our effort to comply with HIPAA privacy and security requirements. Our ongoing efforts to comply with privacy regulations and security regulations have and will continue to impose significant costs on us.

Covered entities must report breaches of unsecured protected health information to affected individuals without unreasonable delay, but not to exceed 60 days of discovery of the breach by the covered entity or its agents. Notification must also be made to HHS and, in certain situations involving large breaches, to the media. HHS is required to publish on its website a list of all covered entities that report a breach involving more than 500 individuals. All non-permitted uses or disclosures of unsecured protected health information are presumed to be breaches unless the covered entity or business associate establishes that there is a low probability the information has been compromised. Various state laws and regulations may also require us to notify affected individuals in the event of a data breach involving individually identifiable information.

Violations of the HIPAA privacy and security regulations may result in criminal penalties and in substantial civil penalties per violation. The civil penalties are adjusted annually based on updates to the consumer price index. HHS is required to perform compliance audits. In addition to enforcement by HHS, state attorneys general are authorized to bring civil actions seeking either injunction or damages in response to violations of HIPAA privacy and security regulations that threaten the privacy of state residents. HHS may resolve HIPAA violations through informal means, such as allowing a covered entity to implement a corrective action plan, but HHS has the discretion to move directly to impose monetary penalties and is required to impose penalties for violations resulting from willful neglect. We are also subject to any federal or state privacy-related laws that are more restrictive than the privacy regulations issued under HIPAA. These laws vary and could impose additional penalties and subject us to additional privacy and security restrictions. For example, the Federal Trade Commission uses its consumer protection authority to initiate enforcement actions in response to data breaches. In addition, various states have enacted, and other states are considering, new laws and regulations concerning the privacy and security of consumer and other personal information. To the extent we are subject to such requirements, these laws and regulations often have far-reaching effects, are subject to amendments and changing requirements and updates to regulators’ enforcement priorities, may require us to modify our data processing practices and policies, may require us to incur substantial costs and expenses to comply and may subject our business to a risk of increased potential liability. These laws and regulations often provide for civil penalties for violations, as well as a private right of action for data breaches, which may increase the likelihood or impact of data breach litigation. Any failure or perceived failure, by us or by third parties with whom we work, to comply with these data protection, privacy and security, or consumer protection laws and regulations could result in enforcement actions, including fines and liability, claims for damages, reputational harm, and other adverse effects on our business, financial condition and results of operations.

Intellectual Property

Table of Contents

We own a number of active trademark registrations, The failure to protect our intellectual property assets could have a material adverse effect on our business; however, the loss of any single trademark or service mark, taken alone, would not have a material adverse effect on the Company as a whole.

Legal Proceedings

From time to time, we may receive inquiries or subpoenas from state regulators, state Medicaid Fraud Control units, fiscal intermediaries, CMS, the U.S. Department of Justice and other government entities regarding various Medicare and Medicaid issues. In addition, we may be subject to other claims and lawsuits arising in the ordinary course of our business including lawsuits and claims related to billing practices and the administration of charity care policies at our practices. Based on current knowledge, management does not believe that loss contingencies arising from pending legal, regulatory and governmental matters, including the matters described herein, will have a material adverse effect on the consolidated financial position or liquidity of the Company.

Insurance

As part of our business of providing oncology care to our patients, we may be subject to legal actions alleging liability on our part. To cover claims arising out of the operations of our clinics and providers, we maintain professional malpractice liability insurance and general liability insurance on a claims-made basis in excess of those amounts for which we are self-insured, in amounts we believe to be sufficient for our operations. We also maintain umbrella liability coverage for claims which, due to their nature or amount, are not covered by our other insurance policies. However, our insurance coverage does not cover all claims against us or may not continue to be available at a reasonable cost for us to maintain adequate levels of insurance.

Employees and Human Capital Resources

As of December 31, 2023, we employed approximately 1,525 employees, including approximately 206 physicians and advanced practice providers that we employ through our physician owned subsidiaries AON Partners and Partners of Maryland. None of our employees are represented by a labor union or party to a collective bargaining agreement. We consider our relations with our employees to be good.

The healthcare industry, and in particular, oncology care, is currently facing workforce challenges and this has become a significant operating issue for healthcare providers. A multipronged approach including staff retention bonuses, market adjustments to compensation, continuation of annual bonuses, competitive fringe benefits including access to robust health insurance and retirement programs have assisted in increasing the retention of our providers and employees. We believe that these efforts will aid in our ability to acquire new clinics and retain our current clinics. Due to the challenges above and other factors, our practices, like many other healthcare providers, have experienced rising labor costs. We may be required to continue to enhance wages and benefits to recruit and retain healthcare providers.

Environmental Matters

We are subject to a number of federal, state and local environmental laws, rules and regulations that govern, among other things, our disposal of medical waste, as well as our use, storage, transportation and disposal of hazardous and toxic materials. In addition, we could be affected by climate change to the extent that climate change results in severe weather conditions or other disruptions impacting the communities in which our facilities are located or adversely impacts general economic conditions, including in communities in which our facilities are located. At the current time, our compliance with environmental legal requirements, including legal requirements relating to climate change, does not have a material effect on our capital expenditures, financial results or operations. However, it is possible that developments may arise in the future as a result of climate change or other environmental developments that we are unable to currently predict.

Properties

Our principal corporate offices are located in Fort Myers, Florida where we lease approximately 9,500 square feet of office space that expires in 2030. We use this facility for administration, billing and collections, technology and development and professional services. We believe that our facilities are adequate to meet our needs for the immediate future, and that, should it be needed, suitable additional space will be available to accommodate any such expansion of our operations.

Table of Contents

We lease all of the 87 properties used for our practice locations as well as administrative facilities under operating leases. As of December 31, 2023, we have leases located in Washington, Idaho, Nevada, Arizona, Iowa, Missouri, Arkansas, Louisiana, Michigan, Indiana, Ohio, Maryland, Virginia, Florida, North Carolina, South Carolina, Georgia, Texas, and the District of Columbia. Generally, our leases are “net” leases, which require us to pay all of the cost of insurance, taxes, maintenance, and utilities. We intend to lease the premises for any new practice locations. Our typical practice occupies an average of 5,800 square feet.

Additional Information

We are subject to the reporting and information requirements of the Securities and Exchange Act of 1934, as amended, and as a result are obligated to file or furnish, as applicable, annual, quarterly, and current reports, proxy statements, and other information with the SEC. We make these documents and other information available free of charge on our website (https://investors.aoncology.com) as soon as reasonably practicable after we electronically file them with, or furnish them to, the SEC. Information on our website does not constitute part of the Report. In addition, the SEC maintains a website (http://www.sec.gov) that contains our annual, quarterly, and current reports, proxy and information statements, and other information we electronically file with, or furnish to, the SEC.

The risk factors described below disclose both material and other risks, and are not intended to be exhaustive and are not the only risks facing us. Additional risks not currently known to us or that we currently deem to be immaterial, or which are not identified because they are generally common to businesses, also may materially adversely affect our business, financial condition, results of operations and cash flows in future periods. The following discussion should be read in conjunction with our consolidated financial statements and notes to the consolidated financial statements included herein, as well as our other public filings with the Securities and Exchange Commission.

Risks Related to Our Business and Industry

In order to execute our growth strategy, we will need to acquire oncology practices and affiliated care providers (“Network Practices”). Our ability to grow depends upon a number of factors, including our ability to obtain referrals for cancer patient care services, identify appropriate physician practices to acquire, enter into contracts with such additional Network Practices, obtain leases, identify appropriate facilities to acquire, complete internal buildouts of new facilities within proposed timelines and budgets, and hire and retain employees including but not limited to physicians affiliated with Network Practices. We cannot guarantee that we will be successful in pursuing our growth strategy.

Our growth strategy involves a number of risks and uncertainties, including that:

•we and our Network Practices may not be able to successfully enter into contracts with local payors on terms acceptable to us or at all. In addition, we compete for payor relationships with other healthcare organizations, many of whom may have greater resources than we do. This competition may intensify due to the ongoing consolidation in the healthcare industry, which may increase our costs to pursue such opportunities. Patients may also choose providers with more competitive contracted rates than we are able to negotiate;

•we will require additional capital and resources in order to acquire additional Network Practices;

•we cannot make any assurance that we will be able to maintain relationships with our Network Practices;

•through our Network Practices, we may not be able to recruit or retain a sufficient number of new patients to execute our growth strategy, and we may incur substantial costs to recruit new patients and we may be unable to recruit a sufficient number of new patients to offset those costs;

•we may not be able to contract with a sufficient numbers of physicians and other staff and may fail to integrate our employees, particularly our medical personnel, into our care model;

•our Network Practices may not conform to our exact business model, which may impact their profitability and in-turn, our profitability;

•when expanding our business into new states, we may be required to comply with laws and regulations that may differ from states in which we currently operate;

•we may not be able to easily monitor and track changes to state and local laws in the states in which we operate, which could increase our legal exposure; and

•depending upon the nature of the local market, we may not be able to implement our business model in every local market that we enter, which could negatively impact our revenues and financial condition.

Table of Contents

There can be no assurance that we will be able to successfully capitalize on growth opportunities, which may negatively impact our business model, revenues, results of operations and financial condition.

Our Network Practices primarily depend on reimbursement from third-party payors, as well as payments by individuals, which could lead to delays, denials, or uncertainties in the reimbursement process.

The reimbursement process is complex and can involve lengthy delays. Although we recognize revenue when our Network Practices provide services to patients, our Network Practices may from time to time experience delays in receiving the associated payments. In addition, third-party payors may disallow, in whole or in part, requests for reimbursement based on determinations that the patient is not eligible for coverage, certain amounts are not reimbursable under plan coverage or the services provided that were not medically necessary or additional supporting documentation is necessary. Retroactive adjustments may change amounts realized from third-party payors. Our Network Practices are subject to audits by such payors, including governmental audits of our Medicare and Medicaid claims, and may be required to repay these payors if a finding is made that we were incorrectly reimbursed. Delays and uncertainties in the reimbursement process may adversely affect accounts receivable, increase the overall costs of collection and cause us to incur additional costs associated with raising capital. Third-party payors are also increasingly focused on controlling healthcare costs, and such efforts, including any revisions to reimbursement policies, may further complicate and delay our Network Practices’ reimbursement claims.

In addition, certain of the patients are covered under health plans that require the patient to cover a portion of their own healthcare expenses through the payment of copayments or deductibles. Our Network Practices may not be able to collect the full amounts due with respect to these payments that are the patient’s financial responsibility, or in those instances where physicians provide services to uninsured individuals. To the extent permitted by law, amounts not covered by third-party payors are the obligations of individual patients for which our Network Practices may not receive whole or partial payment. Any increase in cost shifting from third-party payors to individual patients, including as a result of high deductible plans for patients, increases our collection costs and reduces overall collections, which we may not be able to offset such additional costs with sufficient revenue.

In response to the COVID-19 pandemic, the Centers for Medicare and Medicaid Services (CMS), the federal agency responsible for administering the Medicare program, made several changes in the manner in which Medicare will pay for telehealth visits, many of which relax previous requirements, including site requirements for both the providers and patients, telehealth modality requirements and others. State law applicable to telehealth, particularly licensure requirements, has also been relaxed in many jurisdictions as a result of the COVID-19 pandemic. It is unclear which, if any, of these changes will remain in place permanently and which will be rolled-back following the COVID-19 pandemic. If regulations change to restrict our Network Practices’ ability to deliver care through telehealth modalities, our financial condition and results of operations may be adversely affected.

A significant portion of our revenue is derived from a limited number of health insurance and medical group companies. Those payors could take action to remove, exclude, delay, or otherwise prevent the inclusion of our Network Practices in their provider networks.

Our operations are dependent on a concentrated number of payors with whom our Network Practices contract to provide services to patients. We generally manage our Network Practices’ payor contracts on a state by state basis, entering into a separate contract in each state with the local affiliate of the relevant payor such that no one local payor contract accounts for a majority of our collective revenue. We believe that a majority of our Network Practices’ revenues will continue to be derived from a limited number of key payors, which may terminate their contracts with our Network Practices or the individual Network Practice physicians credentialed by them upon the occurrence of certain events. The sudden loss of any of our network Practices’ payors, or the renegotiation of any of our Network Practices’ payor contracts, could adversely affect our operating results. In the ordinary course of business, we engage in active discussions and renegotiations with payors in respect of the services our Network Practices provide and the terms of our Network Practices’ payor agreements. As the payors’ businesses respond to market dynamics and financial pressures, and as payors make strategic business decisions in respect of the lines of business they pursue and programs in which they participate, certain of the payors may seek to renegotiate or terminate their agreements with our Network Practices. These discussions could result in reductions to the fees and changes to the scope of services contemplated by the original payor contracts and consequently could negatively impact our revenues, business and prospects.

Because we rely on a limited number of payors for a significant portion of our Network Practices’ revenues, we depend on the creditworthiness of these payors. The payors are subject to a number of risks including reductions in

Table of Contents

payment rates from governmental programs, higher than expected health care costs and lack of predictability of financial results when entering new lines of business, particularly with high-risk populations. If the financial condition of our Network Practices’ payors declines, our financial results could be impacted. Should one or more of our Network Practices’ payors declare bankruptcy, be declared insolvent or otherwise be restricted by state or federal laws or regulation from continuing in some or all of their operations, this could adversely affect our ongoing revenues, the collectability of our accounts receivable, our bad debt reserves and our net income.

Although our Network Practices have long-term contracts with many payors, these contracts may be terminated before their term expires for various reasons, such as changes in the regulatory landscape and poor performance by our Network Practices and our affiliated providers, subject to certain conditions. Certain of the payor contracts are terminable immediately upon the occurrence of certain events. Certain of the payor contracts may be terminated immediately by the payor if our Network Practices lose applicable licenses, go bankrupt, lose their liability insurance or receive an exclusion, suspension or debarment from state or federal government authorities. Additionally, if a payor were to lose applicable licenses, go bankrupt, lose liability insurance, become insolvent, file for bankruptcy or become subject to exclusion, suspension or debarment from state or federal government authorities, the Network Practices’ contract with such payor could in effect be terminated. In addition, certain of the payor contracts may be terminated immediately if a Network Practice becomes insolvent or file for bankruptcy. If any of the contracts with the Network Practice’s payors are terminated, the Network Practice may not be able to recover all fees due under the terminated contract, which may adversely affect our operating results.

A significant portion of our revenue is derived from a limited number of our Network Practices. If there are unforeseen disruptions in the businesses of our top Network Practices or these Network Practices terminate their contracts with us, our revenue could decline.

For the fiscal year ended December 31, 2023, our top ten Network Practices generated approximately 67.3% of our revenue. Unforeseen disruptions to these Network Practices could have a significant adverse effect on our revenues. Furthermore, while we enter into long-term contracts with our Network Practices, under certain circumstances and conditions, either party may terminate. The Network Practices have no obligation to renew their contracts after the initial term expires. In addition, our Network Practices may negotiate terms less advantageous to us upon renewal, which may reduce our revenue from them. If our top ten Network Practices terminate their contracts, decide not to renew their contracts, or renew their contracts on less favorable terms or at lower fee levels, our revenue may decline significantly, or our future growth may be constrained.

AON has identified material weaknesses in its internal control over financial reporting. If AON is unable to remediate these material weaknesses, or if it identifies additional material weaknesses in the future or otherwise fails to maintain effective internal control over financial reporting, AON may not be able to accurately or timely report its financial condition or results of operations, which may adversely affect investor confidence in AON’s business and the value of AON common stock.

As a public company, AON will be required to furnish a report by management on the effectiveness of our internal control over financial reporting beginning with our second annual report on Form 10-K. If AON is unable to establish or maintain appropriate internal control over financial reporting or implement these additional requirements in a timely manner or with adequate compliance, it could result in material misstatements in its consolidated financial statements, failure to meet its reporting obligations on a timely basis, increases in compliance costs, and subject AON to adverse regulatory consequences, all of which may adversely affect investor confidence in AON and the value of AON common stock.

As of December 31, 2023, material weaknesses existed in our internal control over financial reporting. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of AON’s annual or interim financial statements will not be prevented or detected on a timely basis.

The material weaknesses that AON identified were as follows:

•The Company did not design and maintain an effective control environment commensurate with its financial reporting requirements. Specifically, the Company lacked a sufficient complement of resources with (i) an appropriate level of accounting knowledge, training and experience to appropriately analyze, record and disclose accounting matters timely and accurately, and (ii) an appropriate level of knowledge and experience to establish

Table of Contents

effective processes and controls. Additionally, the lack of a sufficient complement of resources resulted in an inability to consistently establish appropriate authorities and responsibilities in pursuit of its financial reporting objectives, as demonstrated by, among other things, insufficient segregation of duties in its finance and accounting functions.

•The Company did not effectively design and maintain effective controls in response to the risks of material misstatement. Specifically, changes to existing controls or the implementation of new controls have not been sufficient to respond to changes to the risks of material misstatement to financial reporting.

These material weaknesses contributed to the following additional material weaknesses:

•The Company did not design and maintain effective controls to identify, analyze, account for and disclose non-routine, unusual or complex transactions. Specifically, the Company did not design and maintain controls to account for its business combinations, asset acquisitions, clinical trial agreements, and related party transactions.

•The Company did not design and maintain effective controls related to the period-end financial reporting process, including designing and maintaining formal accounting policies, procedures and controls to achieve complete and accurate financial accounting, reporting and disclosures. Additionally, the Company did not design and maintain controls over the preparation and review of account reconciliations and journal entries, including maintaining appropriate segregation of duties.

•The Company did not design and maintain effective controls to achieve complete, accurate and timely accounting of accrued liabilities.

•The Company did not design and maintain effective controls to achieve complete, accurate and timely accounting of revenue and accounts receivable. Specifically, the Company did not design and maintain controls over the inputs, assumptions, and calculations to develop our contractual allowances.

•The Company did not design and maintain effective information technology (“IT”) general controls for information systems that are relevant to the preparation of its financial statements. Specifically, the Company did not design and maintain: (i) program change management controls to ensure that program and data changes are identified, tested, authorized, and implemented appropriately; (ii) user access controls to ensure appropriate segregation of duties and to adequately restrict user and privileged access to appropriate personnel; (iii) computer operations controls to ensure that processing and transfer of data, and data backups and recovery are monitored; and (iv) program development controls to ensure that new software development is tested, authorized and implemented appropriately.

The material weaknesses above resulted in a revision to the Company’s previously issued financial statements as of and for the year ended December 31, 2020 as well as audit adjustments to the Company’s financial statements as of and for the year ended December 31, 2021 related to the amortization of leasehold improvements within property and equipment, non-controlling interest, accrued liabilities, operating expenses, and related financial disclosures. A revision was also made to the Company’s previously issued condensed consolidated interim financial statements as of and for the nine-month period ended September 30, 2022 related to marketable securities, cash and cash equivalents, patient service revenue, net, patients accounts receivables, net, accrued other, and cost of revenue. Additionally, these material weaknesses could result in further misstatements of the aforementioned account balances or disclosures that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.

The Company is in the process of designing and implementing measures designed to improve our internal control over financial reporting and remediate the control deficiencies which led to the material weaknesses.

The Company’s remediation measures are ongoing and include the following:

•The Company enhanced the technical capabilities of its accounting department via the hiring of an SEC Reporting Manager and intends to seek additional opportunities to further expand its full-time accounting leadership team going forward. Furthermore, the Company will continue to leverage third-party consultants for its technical accounting needs whenever specific technical accounting competencies are required;

Table of Contents

•Management continues to enhance its review process for unusual, non-routine or complex transactions. These enhancements include, but are not limited to, when appropriate, the involvement of non-finance personnel (such as legal or operations personnel) in order to verify the validity and proper accounting treatment of such transactions;

•During 2023, management collaborated with outside consultants possessing significant financial reporting and internal control expertise to perform an extensive review of the design of the Company's internal controls over financial reporting. This review included the identification of internal control deficiencies and the development of corresponding remediation plans for each of the deficiencies identified. These internal control deficiencies identified and corresponding remediation plans included, but were not limited to, the following: improvements to the financial close and reporting process, accounting for contractual allowances related to revenue recognition, the identification of related party transactions, and the timely development of quality estimates related to accrued liabilities;

•Management is gaining a better understanding of system functionality through the review of permissions and profiles to be executed during the periodic user access reviews to be conducted going forward for each IT application that is significant to the Company's financial reporting objectives, and intends subsequently reconfigure profiles with appropriate permissions to better align with job responsibilities and enforce segregation of duties;

•The Company enhanced its financial close process by introducing additional layers of independent reviews by appropriately qualified individuals and improving the precision and timeliness of reviews applied to various period-end activities and financial result analyses, including journal entries, account reconciliations, revenue recognition, and accrued liabilities. Additionally, the Company is developing evidence of review standards to be consistently applied to its various period-end control activities going forward, thereby requiring control owners to better formally document the operation of these controls; and

•The Company has designed and implemented a broad suite of ITGCs over change management, the review and update of user access rights and privileges, controls over batch jobs and data backups, and program development approvals and testing. During 2024, the Company intends to continue improving its ITGC environment by more uniformly applying password parameter requirements across its base of IT applications that are significant to its financial reporting objectives, as well as by enhancing the precision of its periodic user access reviews for these systems.

AON has begun the process to remediate its identified material weaknesses as detailed above. The material weaknesses will not be considered remediated until management completes the design and implementation of the processes and controls described above and the controls operate for a sufficient period of time, and AON has concluded, through testing, that the newly implemented and enhanced controls are operating effectively. At this time, AON cannot predict the success of such efforts or the outcome of future assessments of the remediation efforts. AON’s current controls and any new controls that it develops may become inadequate because of changes in conditions in its business, personnel, IT systems and applications, or other factors. If AON fails to remediate AON’s existing material weakness or identifies new material weaknesses in its internal controls over financial reporting, if it is unable to comply with the requirements of Section 404 of the Sarbanes-Oxley Act in a timely manner, or if it is unable to conclude that its internal controls over financial reporting are effective, it is possible that a material misstatement of AON’s financial statements would not be prevented or detected on a timely basis, investors may lose confidence in the accuracy and completeness of AON’s financial reports, and the market price of AON Class A Common Stock could be negatively affected.

Our services are concentrated in certain geographic areas and populations exposing us to unfavorable changes in local benefit costs, reimbursement rates, competition and economic conditions.

Our services are concentrated in certain geographic areas in the United States. Unfavorable changes in health care or other benefit costs or reimbursement rates or increased competition in the states in which we operate or any other geographic area where our Network Practices are concentrated in the future could therefore have a disproportionately adverse effect on our operating results. Additionally, the geographic concentration of a significant portion of our Network Practices may make them more vulnerable to events such as an outbreak of a pandemic similar to the COVID-19 pandemic.

The AON PNC Loans and the associated restrictive covenants thereunder could adversely affect our financial condition and will restrict our ability to raise capital.

Table of Contents

On April 30, 2021, we entered into the AON PNC Loans with PNC Bank National Association (“PNC”). The AON PNC Loans contains various restrictive and financial covenants, including restrictions on indebtedness, leverage ratio, restricts our ability to (i) incur indebtedness other than (a) in connection with and as allowed under certain provisions of the agreements governing the AON PNC Loans or (b) in ordinary course of business, (ii) permit any lien or encumbrance upon our property except as generally permitted by PNC or as specifically enumerated in the agreements governing the AON PNC Loans, (iii) (a) purchase or redeem any of our membership interests, (b) declare or pay any dividend or set aside any funds for any such purpose (c) prepay, purchase or redeem any other debt, (d) lend or advance any funds or (e) repay any loans or advances to, for or from any of our affiliates, except, for each of the foregoing, as specifically permitted under the AON PNC Loans, (iv) merge or consolidate with or into, or convey, transfer, lease or otherwise dispose of (whether in one transaction or in a series of transactions) all or substantially all of our assets (whether now owned or hereafter acquired) to, any person or entity, (v) without prior written consent, make any change in any borrower’s name, identity, corporate structure or location under the AON PNC Loans or make any other change in such borrower’s identity or corporate structure, or (vi) acquire another business (via assets or equity) unless certain other requirements are met, including that acquisitions via capital stock may only be of a subsidiary of AON. Subject to customary exceptions and exclusions, our obligations under the AON PNC Loans are guaranteed by a perfected, first-priority security interest in substantially all of our assets, including our intellectual property and the equity ownership interests directly and indirectly held by us in our wholly-owned subsidiaries and excluding certain assets used in connection with medical services. Compliance with such covenants and our indebtedness will result in the following, which could materially and adversely affect our business, financial condition and results of operations:

•require us to dedicate a substantial portion of cash and cash equivalents to the payment of interest on, and principal of, the indebtedness, which will reduce the amounts available to fund working capital, capital expenditures, product development efforts and other general corporate purposes;

•oblige us to comply with negative covenants restricting our activities, including limitations on dispositions, mergers or acquisitions, encumbering our intellectual property, incurring indebtedness or liens, paying dividends, making investments and engaging in certain other business transactions;

•limit our flexibility in planning for, or reacting to, changes in our business and our industry;

•place us at a competitive disadvantage compared to our competitors who have less debt or competitors with comparable debt at more favorable interest rates;

•limit our ability to borrow additional amounts for working capital, capital expenditures, research and development efforts, acquisitions, debt service requirements, execution of our business strategy and other purposes and otherwise restrict our financing options.

Furthermore, because the interests of the lenders may potentially differ from ours and from those of our stockholders, we may be unable to engage in transactions or other activities that may be beneficial to our stockholders. The covenants under the agreements governing the AON PNC Loans could materially and adversely affect our business, financial condition and results of operations.

Servicing our indebtedness requires a significant amount of cash. Our ability to repay the principal of, to pay interest on or to refinance our indebtedness depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not generate cash flow from operations in the future sufficient to service our indebtedness. If we are unable to generate cash flow, we may be required to adopt one or more alternatives, such as restructuring debt or obtaining additional financing on terms that may be unfavorable to us or highly dilutive. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at the time we seek to refinance such indebtedness. Our inability to satisfy our debt obligations could materially and adversely affect our financial position and results of operations.

A failure to comply with the conditions of the AON PNC Loans could result in an event of default. An event of default under the AON PNC Loans includes, among other things, a failure to pay any amount due under the AON PNC Loans. If we fail to comply with any of the covenants under our indebtedness and are unable to obtain a waiver or amendment, the lenders may, among other things, accelerate our outstanding indebtedness and exercise rights with respect to collateral securing our outstanding indebtedness, each of which could have an adverse effect on our business, financial condition and results of operations.

Any of these events could materially and adversely affect our business, financial condition and results of operations.

Table of Contents

The AON PNC Loans subject us to interest rate risk, which could cause our debt service obligations to increase significantly and potentially limit our ability to effectively refinance our indebtedness as it matures.

Borrowings under the AON PNC Loans bear interest at variable rates and expose us to interest rate risk. If interest rates increase and we do not hedge such variable rates, our debt service obligations on the variable rate indebtedness will increase even though the amount borrowed will remain the same, which will negatively impact our net income and operating cash flows, including cash available for servicing our indebtedness.

Additionally, our ability to refinance portions of our indebtedness in advance of their maturity dates depends on securing new financing bearing interest at rates that we are able to service. While we believe that we currently have adequate cash flows to service the interest rates currently applicable to our indebtedness, if interest rates were to continue to rise significantly, we might be unable to maintain a level of cash flows from operating activities sufficient to meet our debt service obligations at such increased rates.

A pandemic, epidemic or outbreak of an infectious disease in the United States or worldwide, similar to the outbreak of COVID-19 or the continuation of such an outbreak, could adversely affect our business, financial condition, results of operations and growth.

If a pandemic, epidemic or outbreak of an infectious disease occurs in the United States or worldwide, our business may be adversely affected.

To the extent a pandemic, epidemic or outbreak of an infectious disease which occurs in the United States or worldwide adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described in this “Risk Factors” section, including but not limited to those relating to cyberattacks and security vulnerabilities, interruptions or delays due to third-parties, or our ability to raise additional capital or generate sufficient cash flows necessary to fulfill our obligations under our existing indebtedness or to expand our operations.

If we are unable to attract new patients and to obtain new payor contracts our revenue growth will be adversely affected.

To increase our revenue, our business strategy is to expand the number of oncology clinics and affiliated physicians in our network. In order to support such growth, we must continue to win new contracts and retain or grow existing contracts with payors. Our Network Practices face competition from other oncology providers. If our Network Practices are unable to convince potential payors and patients of the benefits of our value-based system, or if potential or existing payors and patients prefer the care provider model of one of our competitors, we may not be able to effectively implement our growth strategy, which depends on our ability to attract new patient referrals and payors for our Network Practices. Network Practices’ inability to obtain new payor agreements and patient referrals and retain existing payors and patients would harm our ability to execute our growth strategy and may have a material adverse effect on our business operations and financial position.

We face risks associated with estimating the amount of revenue that is recognized under Network Practices’ agreements with health plans, and if our estimates of revenue are materially inaccurate, it could impact the timing and the amount of our revenue recognition or have a material adverse effect on our business, results of operations, financial condition and cash flows.

There are significant risks associated with estimating the amount of revenues that are recognized under Network Practices’ agreements with health plans in a reporting period and it is possible that we may not accurately estimate the amount of such revenues. The billing and collection process is complex due to ongoing insurance coverage changes, geographic coverage differences, differing interpretations of contract coverage and other payor issues, such as ensuring appropriate documentation. Determining applicable primary and secondary coverage for patients, together with the changes in patient coverage that occur each month, requires complex, resource-intensive processes. Errors in determining the correct coordination of benefits may result in refunds to payors. Revenues associated with Medicare and Medicaid programs are also subject to estimating risk related to the amounts not paid by the primary government payor that will ultimately be collectible from other government programs paying secondary coverage, the patient’s commercial health plan secondary coverage or the patient. Collections, refunds and payor recoupments typically continue to occur for up to three years and longer after services are provided. If our estimates of revenues are materially inaccurate, it could impact the timing and the amount of our revenues recognition and have a material adverse impact on our business, results of operations, financial condition and cash flows.

Reductions in government reimbursement rates or changes in the rules governing government healthcare programs could have a material adverse effect on our financial condition and results of operations.

Our Network Practices receive a significant portion of revenue directly from Medicare. In addition, many private payors base their reimbursement rates on the published Medicare rates or, in the case of Medicare Advantage, are themselves reimbursed by Medicare for the services our Network Practices provide.

As a result, our results of operations are, in part, dependent on government funding levels for Medicare programs, particularly Medicare Advantage programs. Any changes that limit or reduce Medicare Advantage or general Medicare reimbursement levels, such as reductions in or limitations of reimbursement amounts or rates under programs, reductions in funding of programs, expansion of benefits without adequate funding, elimination of coverage for certain benefits, or elimination of coverage for certain individuals or treatments under programs, could have a material adverse effect on our business, results of operations, financial condition and cash flows.

The Medicare program and its reimbursement rates and rules are subject to frequent change. These include statutory and regulatory changes, rate adjustments (including retroactive adjustments), administrative or executive orders and government funding restrictions, all of which may materially adversely affect the rates at which Medicare reimburses our Network Practices for patient care services. Budget pressures often lead the federal government to reduce or place limits on reimbursement rates under Medicare. Implementation of these and other types of measures has in the past and could in the future result in substantial reductions in our revenue and operating margins.

In addition, CMS often changes the rules governing the Medicare program, including those governing reimbursement. Changes that could adversely affect our business include:

•administrative or legislative changes to rates or the bases of payment;

•limits on the services or types of providers for which Medicare will provide reimbursement;

•changes in methodology for patient assessment and/or determination of payment levels;

•the reduction or elimination of annual rate increases; or

•an increase in co-payments or deductibles payable by beneficiaries.

Any reductions in reimbursement rates or the scope of services rendered by our Network Practices being reimbursed could have a material, adverse effect on our financial condition and results of operations or even result in reimbursement rates that are insufficient to cover our operating expenses. Additionally, any delay or default by the government in making Medicare or Medicaid reimbursement payments to our Network Practices or any reduction in patients eligible for such programs could materially and adversely affect our business, financial condition and results of operations.

We cannot predict the effect that health care reform and other changes in government programs may have on our business, financial condition or results of operations.

The impact of healthcare reform legislation and other changes in the healthcare industry and in healthcare spending is currently unknown, but may adversely affect our business, financial condition and results of operations. Our revenue is dependent on the healthcare industry and could be affected by changes in healthcare spending, reimbursement and policy. The healthcare industry is subject to changing political, regulatory and other influences. By way of example, the Affordable Care Act (“ACA”), which was enacted in 2010, made major changes in how healthcare is delivered and reimbursed, and it increased access to health insurance benefits to the uninsured and underinsured populations of the United States.

Since its enactment, there have been judicial, executive and Congressional challenges to certain aspects of the ACA. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA. Prior to the Supreme Court’s decision, President Biden issued an executive order initiating a special enrollment period from February 15, 2021 through August 15, 2021 for purposes of obtaining health insurance coverage through the ACA marketplace. The executive order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare. It is unclear how healthcare reform measures enacted by Congress or implemented by the Biden administration, if any, will impact our business.

Table of Contents

effect through 2030, with the exception of a temporary suspension from May 1, 2020 through March 31, 2022. Under current legislation, the actual reduction in Medicare payments varies from 1% from April 1, 2022 to June 30, 2022, to up to 3% in the final fiscal year of this sequester, unless additional Congressional action is taken. In January 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to several types of providers, including hospitals, imaging centers and cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. New laws may result in additional reductions in Medicare and other healthcare funding, which may materially adversely affect consumer demand and affordability for our products and services and, accordingly, the results of our financial operations. Additional changes that may affect our business include the expansion of new programs such as Medicare payment for performance initiatives for physicians under the Medicare Access and CHIP Reauthorization Act of 2015, or MACRA, which first affected physician payment in 2019. At this time, it is unclear how the introduction of the Medicare quality payment program will impact overall physician reimbursement. The Inflation Reduction Act of 2022, or IRA, signed into law on August 16, 2022, also contains a number of provisions designed to limit or reduce drug prices under the Medicare program, reduce beneficiary out-of-pocket spending under Medicare’s prescription drug benefit, and expand subsidies for individuals to obtain private health insurance under the ACA. While these provisions of the IRA do not apply directly to healthcare providers like our Network Practices, we are continuing to evaluate the potential impact, if any, that the IRA may have on our business.

Such changes in the regulatory environment may also result in changes to our payer mix that may affect our operations and revenue. In addition, certain provisions of the ACA authorize voluntary demonstration projects, which include the development of bundling payments for acute, inpatient hospital services, physician services and post-acute services for episodes of hospital care.

Further, the ACA may adversely affect payers by increasing medical costs generally, which could have an effect on the industry and potentially impact our business and revenue as payers seek to offset these increases by reducing costs in other areas. Uncertainty regarding future amendments to the ACA as well as new legislative proposals to reform healthcare and government insurance programs, along with the trend toward managed healthcare in the United States, could result in reduced demand and prices for our services. We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments and other third party payers will pay for healthcare products and services, which could adversely affect our business, financial condition and results of operations.

Changes in the payor mix of patients and potential decreases in reimbursement rates as a result of consolidation among plans could adversely affect our revenues and results of operations.

The amounts our Network Practices receive for services provided to patients are determined by a number of factors, including the payor mix of patients and the reimbursement methodologies and rates utilized by the patients’ plans. Patient services revenue consists of fee-for-service agreements held by our Network Practices. Under a fee-for-service payor arrangement, our Network Practices collect fees directly from the payor as services are provided. Patient services revenue accounted for substantially all of our total revenue for the year ended December 31, 2023. A significant decrease in the number of fee-for-service arrangements held by our Network Practices could adversely affect our revenues and results of operation.

The healthcare industry has also experienced a trend of consolidation, resulting in fewer but larger payors that have significant bargaining power, given their market share. Payments from payors are the result of negotiated rates. These rates may decline based on renegotiations and larger payors have significant bargaining power to negotiate higher discounted fee arrangements with healthcare providers. As a result, payors increasingly are demanding discounted fee structures or the assumption by healthcare providers of all or a portion of the financial risk related to paying for care provided through capitation agreements.

We face significant competition from other healthcare services providers. Our failure to adequately compete could adversely affect our business.

We and our Network Practices compete directly with national, regional and local providers of healthcare for patients and physicians. There are many other companies and individuals currently providing healthcare services, many of which have been in business longer and/or have substantially more resources. Other companies could enter the healthcare industry in the future and divert some or all of our business. If we expand to other geographies, we expect competition may change based on a number of factors, including the number of competing oncology care facilities in the local market and the types

Table of Contents

of services available at those facilities, our Network Practices’ reputation for quality care of patients, the commitment and expertise of our Network Practices’ medical staff, our local service offerings and community programs, the cost of care in each locality, and the physical appearance, location, age and condition of our facilities. If we are unable to attract patients to our managed clinics, our revenue and profitability will be adversely affected. Some of our competitors may have greater recognition and be more established in their respective communities than we are, and may have greater financial and other resources than we have. Competing oncology care providers may also offer larger facilities or different programs or services than our Network Practices do, which, combined with the foregoing factors, may result in our competitors being more attractive to our current patients, potential patients and referral sources. Furthermore, while we budget for routine capital expenditures at our managed clinics to keep them competitive in their respective markets, to the extent that competitive forces cause those expenditures to increase in the future, our financial condition may be negatively affected. In addition, our relationships with governmental and private third-party payors are not exclusive and our competitors have established or could seek to establish relationships with such payors to serve their covered patients. Additionally, as we expand into new geographies, we may encounter competitors with stronger relationships or recognition in the community in such new geography, which could give those competitors an advantage in obtaining new patients. Individual physicians, physician groups and companies in other healthcare industry segments, including those with which our Network Practices have contracts, and some of which have greater financial, marketing and staffing resources, may become competitors in providing health care services, and this competition may have a material adverse effect on our business operations and financial position.

Competition for physicians and nurses, shortages of qualified personnel or other factors could increase our labor costs and adversely affect our revenue, profitability and cash flows.

Our operations are dependent on the efforts, abilities and experience of our Network Practices’ physicians and clinical personnel. We compete with other healthcare providers, primarily hospitals and other oncology practices, in attracting physicians, nurses and medical staff to support our managed clinics, recruiting and retaining qualified management and support personnel responsible for the daily operations of each of our managed clinics and in our Network Practices contracting with payors in each of our markets. In some markets, the lack of availability of clinical personnel has become a significant operating issue facing all healthcare providers. This shortage may require us and our Network Practices to continue to enhance wages and benefits to recruit and retain qualified personnel or to contract for more expensive temporary personnel. We also depend on the available labor pool of semi-skilled and unskilled workers in each of the markets in which we operate.

If our labor costs increase, we may not be able to raise rates to offset these increased costs. Because a significant percentage of our revenue consists of fixed, prospective payments, our ability to pass along increased labor costs is limited. In particular, if labor costs rise at an annual rate greater than our net annual consumer price index basket update from Medicare, our results of operations and cash flows will likely be adversely affected. Any union activity at our managed clinics that may occur in the future could contribute to increased labor costs. Certain proposed changes in federal labor laws and the National Labor Relations Board’s modification of its election procedures could increase the likelihood of employee unionization attempts. Although none of our employees or the employees of our Network Practices are currently represented by a collective bargaining agreement, to the extent a significant portion of our employee base unionizes, it is possible our labor costs could increase materially. Our failure to recruit and retain qualified management and medical personnel for our Network Practices, or to control our collective labor costs, could have a material adverse effect on our business, prospects, results of operations and financial condition.

Because competition for qualified personnel is intense, we may not be able to attract and retain the highly skilled employees we need to execute our business strategies and growth plans.

To execute on our growth plan, we and our Network Practices must attract and retain highly qualified personnel. Competition for highly qualified personnel is intense, especially for physicians and other medical professionals who are experienced in providing oncology care services. We and our Network Practice have, from time to time, experienced, and we expect to continue to experience, difficulty in hiring and retaining employees with appropriate qualifications. Many of the companies and healthcare providers with which we compete for experienced personnel have greater resources than we have. If we and our Network Practices hire employees from competitors or other companies or healthcare providers, their former employees may attempt to assert that these employers or we have breached certain legal obligations, resulting in a diversion of our time and resources.

As we become a more mature company, we may find our recruiting efforts more challenging. The incentives to attract, retain, and motivate employees provided by our stock options and other equity awards, or by other compensation

Table of Contents

arrangements, may not be as effective as in the past. As such, we may not be successful in continuing to attract and retain qualified personnel. Our recruiting efforts may also be limited by laws and regulations, such as restrictive immigration laws, and restrictions on travel or availability of visas. If we fail to attract new personnel or fail to retain and motivate our current personnel, our business and future growth prospects could be harmed.

If our Network Practices and the physicians affiliated therewith are unable to provide consistently high quality of care, our business will be adversely impacted.

Our business is dependent upon our Network Practices and the physicians affiliated therewith providing high-quality care to patients. In particular, the ability to attract and retain patients and patient referrals is dependent upon providing cost effective, quality patient care that meets or exceeds the patients’ and payors’ expectations. We depend on third parties for certain of the patient care needs. If we, our Network Practices or the physicians affiliated therewith fail to provide service that meets the patients’ and payors’ expectations, we may have difficulty retaining or growing the patient base, which could adversely affect our business, financial condition and results of operations.

We expect the importance of high-quality patient experience to increase as we, through our Network Practices, expand our business and pursue new lives served. Any failure to maintain high-quality patient experience, or a market perception that we do not maintain high-quality care, could harm our reputation and our ability to grow the number of lives served, and our business, results of operations, and financial condition. Additionally, as the number of lives served by our Network Practices in our managed clinics grows, we will need to hire additional personnel to provide quality care at scale. If we, our Network Practices or the physicians affiliated therewith are unable to provide such care, our business, results of operations, financial condition, and reputation could be harmed.

If certain of our suppliers do not meet our needs, if there are material price increases on supplies, if we are not reimbursed or adequately reimbursed for drugs purchased or if we are unable to effectively access new technology or superior products, it could negatively impact the ability of our Network Practices to effectively provide the services we offer and could have a material adverse effect on our business, results of operations, financial condition and cash flows.

If our suppliers do not meet our Network Practices’ needs for the products they supply, including in the event of a product recall, shortage or dispute, and are not able to find adequate alternative sources, if our Network Practices experience material price increases from these suppliers that we are unable to mitigate, or if some of the drugs that our Network Practices purchase are not reimbursed or not adequately reimbursed by commercial or government payors, it could have a material adverse impact on our business, results of operations, financial condition and cash flows. In addition, the technology related to the products critical to the services we provide is subject to new developments which may result in superior products. If we are not able to access superior products on a cost-effective basis or if suppliers are not able to fulfill our requirements for such products, we and our Network Practices could face patient attrition and other negative consequences which could have a material adverse effect on our business, results of operations, financial condition and cash flows.

We depend on our information technology systems, and those of our third-party vendors, contractors and consultants, and any failure or significant disruptions of these systems, security breaches or loss of data could materially adversely affect our business, financial condition and results of operations.

Our business is dependent on maintaining effective information systems as well as the integrity and timeliness of the data we use to serve patients, support our care teams and operate our business. Because of the large amount of data that we collect and manage, it is possible that hardware failures or errors in our systems could result in data loss or corruption or cause the information that we collect to be incomplete or contain inaccuracies that our partners regard as significant. If our data were found to be inaccurate or unreliable due to fraud or other error, or if we, or any of the third-party service providers we engage, were to fail to maintain information systems and data integrity effectively, we could experience operational disruptions that may impact patients and care teams and hinder our ability to provide services, retain and attract patients, establish appropriate pricing for services, manage patient risk profiles, establish reserves, report financial results timely and accurately and maintain regulatory compliance, among other things.

Our information technology strategy and execution are critical to our continued success. We must continue to invest in long-term solutions that will enable us to anticipate patient needs and expectations, enhance the patient experience, act as a differentiator in the market and protect against cybersecurity risks and threats. We believe our success is dependent, in large part, on maintaining the effectiveness of existing technology systems and continuing to deliver and enhance technology systems that support our business processes in a cost-efficient and resource-efficient manner.

regulatory and legislative changes will place additional demands on our information technology infrastructure that could have a direct impact on resources available for other projects tied to our strategic initiatives. In addition, recent trends toward greater patient engagement in health care require new and enhanced technologies, including more sophisticated applications for mobile devices. Connectivity among technologies is becoming increasingly important. We must also develop new systems to meet current market standards and keep pace with continuing changes in information processing technology, evolving industry and regulatory standards and patient needs. Failure to do so may present compliance challenges and impede our ability to deliver services in a competitive manner. Further, because system development projects are long-term in nature, they may be more costly than expected to complete and may not deliver the expected benefits upon completion.

Security incidents compromising the confidentiality, integrity, and availability of our confidential or personal information and our and our third-party service providers’ information technology systems could result from cyber-attacks, computer malware, viruses, social engineering (including spear phishing and ransomware attacks), credential stuffing, supply chain attacks, efforts by individuals or groups of hackers and sophisticated organizations, including state-sponsored organizations, errors or malfeasance of our personnel, and security vulnerabilities in the software or systems on which we and our third party service providers rely. As techniques used by cyber criminals change frequently, a disruption, cyberattack or other security breach of our information technology systems or infrastructure, or those of our third-party service providers, may go undetected for an extended period and could result in the theft, transfer, unauthorized access to, disclosure, modification, misuse, loss or destruction of our employee, representative, customer, vendor, consumer and/or other third-party data, including sensitive or confidential data, personal information and/or intellectual property. We and certain of our service providers are from time to time, subject to cyberattacks and security incidents, and we cannot guarantee that our security efforts will prevent breaches or breakdowns of our or our third-party service providers’ information technology systems. While we do not believe that we have experienced any significant system failure, accident or security breach to date, if we suffer a material loss or disclosure of health-related or other personal or confidential information as a result of a breach of our information technology systems, including those of our third-party service providers, we may suffer reputational, competitive and/or business harm, incur significant costs and be subject to government investigations, litigation, fines and/or damages, which could have a material adverse effect on our business, prospects, results of operations, financial condition and/or cash flows. Moreover, while we maintain cyber insurance that may help provide coverage for these types of incidents, we cannot assure you that our insurance will be adequate to cover costs and liabilities related to these incidents. Further, our failure to effectively invest in, implement improvements to and properly maintain the uninterrupted operation and data integrity of our information technology and other business systems could adversely affect our results of operations, financial position and cash flow.

We may be subject to legal proceedings and litigation, including intellectual property and privacy disputes, which are costly to defend and could materially harm our business and results of operations.

We and our Network Practices may be party to lawsuits and legal proceedings in the normal course of business. These matters are often expensive and disruptive to normal business operations. We may face allegations, lawsuits and regulatory inquiries, audits and investigations regarding data privacy, security, labor and employment, consumer protection and intellectual property infringement, including claims related to privacy, patents, publicity, trademarks, copyrights and other rights. We may also face allegations or litigation related to our acquisitions, securities issuances or business practices, including public disclosures about our business. Litigation and regulatory proceedings may be protracted and expensive, and the results are difficult to predict. Certain of these matters may include speculative claims for substantial or indeterminate amounts of damages and include claims for injunctive relief. Additionally, our litigation costs could be significant. Adverse outcomes with respect to litigation or any of these legal proceedings may result in significant settlement costs or judgments, penalties and fines, or require us to modify our services or require us to stop serving certain patients or geographies, all of which could negatively impact our geographical expansion and revenue growth. Our Network Practices may also become subject to periodic audits, which would likely increase our regulatory compliance costs and may require us to change our business practices, which could negatively impact our revenue growth. Managing legal proceedings, litigation and audits, even if we achieve favorable outcomes, is time-consuming and diverts the attention of management and our affiliated providers from our business.

The results of regulatory proceedings, litigation, claims, and audits cannot be predicted with certainty, and determining reserves for pending litigation and other legal, regulatory and audit matters requires significant judgment. There can be no assurance that our expectations will prove correct, and even if these matters are resolved in our favor or without significant cash settlements, these matters, and the time and resources necessary to litigate or resolve them, could harm our reputation, business, financial condition, results of operations and the market price of our common stock.

Furthermore, our business exposes our Network Practices and affiliated providers to potential medical malpractice, professional negligence or other related actions or claims that are inherent in the provision of healthcare services. These claims, with or without merit, could cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention of management and our affiliated providers from our core business, harm our reputation and adversely affect our Network Practices’ ability to attract and retain patients, any of which could have a material adverse effect on our business, financial condition and results of operations.

Although we maintain professional liability insurance coverage for our Network Practices and affiliated providers, it is possible that claims against them may exceed the coverage limits of our insurance policies. Even if any professional liability loss is covered by an insurance policy, our liability could exceed the limits of our insurance coverage. Professional liability claims in excess of applicable insurance coverage could have a material adverse effect on our collective business, financial condition and results of operations. In addition, any professional liability claim brought against our Network Practices and affiliated providers, with or without merit, could result in an increase of our professional liability insurance premiums. Insurance coverage varies in cost and can be difficult to obtain, in particular insurance coverage relating to cybersecurity, and we cannot guarantee that we will be able to obtain insurance coverage on behalf of our Network Practices and affiliated providers in the future on terms acceptable to us or at all. If costs of insurance and claims increase, then our collective earnings could decline.

Some jurisdictions preclude Network Practices from entering into non-compete agreements with physicians, and other non-compete agreements and restrictive covenants applicable to certain physicians and other clinical employees may not be enforceable.

Network Practices have employment contracts with physicians and other health professionals in many states. Some of these contracts include provisions preventing these physicians and other health professionals from competing with us both during and after the term of our contract with them. The law governing non-compete agreements and other forms of restrictive covenants varies from state to state. Some jurisdictions prohibit our Network Practices from using non-competition covenants with our professional staff. Other states are reluctant to strictly enforce non-compete agreements and restrictive covenants applicable to physicians and other healthcare professionals. There can be no assurance that our Network Practices’ non-compete agreements related to physicians and other health professionals will be found enforceable if challenged in certain states. In such event, our Network Practices would be unable to prevent physicians and other health professionals formerly employed by our Network Practices from competing with us, potentially resulting in the loss of some of our patients.

Current and future acquisitions may use significant resources, may be unsuccessful, and could expose us to unforeseen liabilities.

As part of our growth strategy, we may pursue acquisitions of oncology and other physician practices and services. These acquisitions may involve significant cash expenditures, debt incurrence, additional operational losses and expenses, and compliance risks that could have a material adverse effect on our financial condition and results of operations. We may not be able to successfully integrate the acquired businesses into ours and our Network Practices’, and therefore, we may not be able to realize the intended benefits from an acquisition. These acquisitions could result in difficulties integrating acquired operations, technologies, and personnel into our business. Such difficulties may divert significant financial, operational, and managerial resources from our existing operations and make it more difficult to achieve our operating and strategic objectives. We and our Network Practices may fail to retain employees or patients acquired through these acquisitions, which may negatively impact the integration efforts. These acquisitions could also have a negative impact on our results of operations if it is subsequently determined that goodwill or other acquired intangible assets are impaired, thus resulting in an impairment charge in a future period.

In addition, these acquisitions involve risks that the acquired businesses will not perform in accordance with expectations; that we may become liable for unforeseen financial or business liabilities of the acquires businesses, including liabilities for failure to comply with applicable healthcare regulations; that the expected synergies associated with acquisitions will not be achieved; and that business judgments concerning the value, strengths and weaknesses of businesses acquired will prove incorrect, which could have a material adverse effect on our financial condition and results of operations.

If we are unable to protect the confidentiality of our trade secrets, know-how and other proprietary and internally developed information, the value of our technology could be adversely affected.

Table of Contents

We may not be able to protect our trade secrets, know-how and other internally developed information adequately. Although we use reasonable efforts to protect this internally developed information and technology, our employees, consultants and other parties (including independent contractors and companies with which we conduct business) may unintentionally or willfully disclose our information or technology to competitors. Enforcing a claim that a third party illegally disclosed or obtained and is using any of our internally developed information or technology is difficult, expensive and time-consuming, and the outcome is unpredictable. We rely, in part, on non-disclosure, confidentiality and assignment-of-invention agreements with our employees, independent contractors, consultants and companies with which we conduct business to protect our internally developed information. These agreements may not be self-executing, or they may be breached and we may not have adequate remedies for such breach. Moreover, third parties may independently develop similar or equivalent proprietary information or otherwise gain access to our trade secrets, know- how and other internally developed information.

Negative publicity regarding the managed healthcare industry generally could adversely affect our results of operations or business.

Negative publicity regarding the managed healthcare industry generally may result in increased regulation and legislative review of industry practices that further increase our costs of doing business and adversely affect our results of operations or business by:

•requiring us to change our products and services;

•increasing the regulatory, including compliance, burdens under which we operate, which, in turn, may negatively impact the manner in which our Network Practices provide services and increase our costs of providing services;

•adversely affecting our ability to market our products or services through the imposition of further regulatory restrictions; or

•adversely affecting our ability to attract and retain patients.

Our managed clinics may be negatively impacted by weather and other factors beyond our control.

Our results of operations may be adversely impacted by adverse conditions affecting our managed clinics, including severe weather events such as hurricanes and flooding, natural disasters such as earthquakes and forest fires. In particular, Fort Myers, Florida where our headquarters are located, experienced significant damage in the wake of Hurricane Ian. We may not fully realize Ian’s impact on Fort Myers for some time, and Fort Myers is likely to be adversely impacted by other severe storms and/or hurricanes in the future. Our results of operations may also be adversely impacted by public health concerns such as contagious disease outbreaks, violence or threats of violence or other factors beyond our control that cause disruption of patient scheduling, displacement of patients, employees and care teams, or force certain of our managed clinics to close temporarily. Our future operating results may be adversely affected by these and other factors that disrupt the operation of our managed clinics.

Our investments in marketable securities are subject to certain risks which could affect our overall financial condition, results of operations, or cash flows.

We invest a portion of our available cash and cash equivalents by purchasing marketable securities in a managed portfolio and direct investments in a variety of debt securities, including corporate debt securities, municipal bonds, and U.S. government and agency debt securities. The primary objective of our investment activity is to maintain the safety of principal, preserve capital and provide for future liquidity requirements while maximizing yields without significantly increasing risk. Should any of our investments or marketable securities lose value or have their liquidity impaired, it could materially affect our overall financial condition. Additionally, should we choose or are required to sell these securities in the future at a loss, our consolidated operating results or cash flows may be materially and adversely affected.

Inflation may adversely affect us by materially increasing our costs.

Recently, inflation has increased throughout the U.S. economy. Inflation can adversely affect us by materially increasing the costs of drugs and medical supplies, labor, administration and other costs of doing business. We may experience material increases in the cost of labor due to a nationwide shortage of nurses and other clinical staff. In an inflationary environment, cost increases may materially outpace our expectations, causing us to use our cash and other liquid assets faster than forecasted. Our ability to pass on increased costs associated with providing healthcare to Medicare and Medicaid patients is limited due to various federal, state and local laws which have been enacted that, in certain cases, limit our ability to increase prices. If this happens, we may need to raise additional capital to fund our operations, which

may not be available in sufficient amounts or on reasonable terms, if at all, sooner than expected. The Company minimizes the impacts of inflation by maintaining strong relationships with its suppliers and renegotiating payor contracts where possible

Risks Related to Our Regulatory Environment

We are dependent on our relationships with our Network Practices to provide healthcare services, and our business would be harmed if those relationships were disrupted or if our arrangements with our Network Practices become subject to legal challenges.

Our contractual relationships with our Network Practices may implicate certain state laws that generally prohibit non-professional entities from providing licensed medical services or exercising control over licensed physicians or other healthcare professionals (such activities generally referred to as the “corporate practice of medicine”) or engaging in certain practices such as fee-splitting with such licensed professionals. The interpretation and enforcement of these laws vary significantly from state to state. There can be no assurance that these laws will be interpreted in a manner consistent with our practices or that other laws or regulations will not be enacted in the future that could have a material and adverse effect on our business, financial condition and results of operations. Regulatory authorities, state boards of medicine, state attorneys general and other parties may assert that, despite the agreements through which we operate, we are engaged in the provision of medical services and/or that our arrangements with our Network Practices constitute unlawful fee-splitting. If a jurisdiction’s prohibition on the corporate practice of medicine or fee-splitting is interpreted in a manner that is inconsistent with our practices, we would be required to restructure or terminate our arrangements with our Network Practices to bring our activities into compliance with such laws. A determination of non-compliance, or the termination of or failure to successfully restructure these relationships could result in disciplinary action, penalties, damages, fines, and/or a loss of revenue, any of which could have a material and adverse effect on our business, financial condition and results of operations. State corporate practice of medicine and fee-splitting prohibitions also often impose penalties on healthcare professionals for aiding in the improper rendering of professional services, which could discourage physicians and other healthcare professionals with whom we contract from providing clinical services.

Our managed clinics and our Network Practices providing professional services at such clinics may become subject to medical liability claims, which could have a material adverse impact on our business.

Our business entails the risk of medical liability claims against us, our Network Practices and their clinicians. Although we, our Network Practices and their clinicians carry insurance covering medical malpractice claims in amounts that we believe are appropriate in light of the risks attendant to our business, successful medical liability claims could result in substantial damage awards that exceed the limits of our and our clinicians’ insurance coverage, and/or plaintiffs in these matters may request punitive or other damages that may not be covered by insurance. In addition, professional liability insurance is expensive and insurance premiums may increase significantly in the future, particularly as we expand our services. As a result, adequate professional liability insurance may not be available to our clinicians, our affiliated practices or to us in the future at acceptable costs or at all.

Any claims made against us or our Network Practices that are not fully covered by insurance could be costly to defend, result in substantial damage awards against us and divert the attention of our management and our Network Practices from our operations, which could have a material adverse effect on our business, financial condition and results of operations. In addition, any claims may adversely affect our business or reputation.

If there is a change in accounting standards by the Financial Accounting Standards Board (“FASB”) or the interpretation thereof affecting consolidation of entities, it could have a material adverse effect on our consolidation of total revenues derived from our Network Practices.

Our financial statements are consolidated in accordance with applicable accounting standards and include the accounts of our Network Practices, which we manage under long-term management services agreements but are not owned by us. Such consolidation for accounting and/or tax purposes does not, is not intended to, and should not be deemed to, imply or provide us any control over the medical decisions of our Network Practices. In the event a change in accounting standards promulgated by the FASB or in interpretation of its standards, we may not be permitted to continue to consolidate the total revenues of such practices which would negatively affect the market price of our common stock.

Table of Contents

Our managed clinics and our Network Practices may be subject to third-party payor audits, which, if adversely determined against us or our Network Practices, may have a material effect on our results of operations and financial condition.

As a result of our Network Practices’ participation in the Medicare and Medicaid programs, our managed clinics and our Network Practices are subject to various governmental inspections, reviews, audits and investigations to verify our compliance with these programs and applicable laws and regulations.

Payors may also reserve the right to conduct audits. We also periodically conduct internal audits and reviews of our regulatory compliance. An adverse inspection, review, audit or investigation could result in:

•refunding amounts we have been paid pursuant to the Medicare or Medicaid programs or from payors;

•state or federal agencies imposing fines, penalties and other sanctions on us;

•temporary suspension of payment for new patients to the facility or agency;

•decertification or exclusion from participation in the Medicare or Medicaid programs or one or more payor networks;

•self-disclosure of violations to applicable regulatory authorities;

•damage to our reputation;

•the revocation of a facility’s or agency’s license; and

•loss of certain rights under, or termination of, our contracts with payors.

If adverse inspections, reviews, audits or investigations occur and any of the results noted above occur, it could have a material adverse effect on our business and operating results. Furthermore, the legal, document production and other costs associated with complying with these inspections, reviews, audits or investigations could be significant.

We are subject to extensive fraud, waste, and abuse laws that may give rise to federal and state audits, investigations, lawsuits and claims against us, the outcome of which may have a material adverse effect on our business, financial condition, cash flows, or results of operations.

The U.S. healthcare industry is heavily regulated and closely scrutinized by federal, state and local governments. Comprehensive statutes and regulations govern the manner in which we provide and bill for services and collect reimbursement from governmental programs and private payors, our contractual relationships and arrangements with healthcare providers and vendors, our marketing activities and other aspects of our operations. Of particular importance are:

•the federal Anti-Kickback Statute, or AKS, which prohibits the knowing and willful offer, payment, solicitation or receipt of any bribe, kickback, rebate or other remuneration for referring an individual, in return for ordering, leasing, purchasing or recommending or arranging for or to induce the referral of an individual or the ordering, purchasing or leasing of items or services covered, in whole or in part, by any federal healthcare program, such as Medicare and Medicaid. A person or entity does not need to have actual knowledge of the statute or specific intent to violate it to have committed a violation;

•the federal physician self-referral law, the Stark Law, which, subject to limited exceptions, prohibits physicians from referring Medicare or Medicaid patients to an entity for the provision of certain designated health services, or DHS, if the physician or a member of such physician’s immediate family has a direct or indirect financial relationship (including an ownership interest or a compensation arrangement) with the entity, and prohibits the entity from billing Medicare or Medicaid for such DHS;

•the federal False Claims Act, or FCA, which imposes civil and criminal liability on individuals or entities that knowingly submit false or fraudulent claims for payment to the government or knowingly make, or cause to be made, a false statement in order to have a false claim paid, including qui tam or whistleblower suits. There are many potential bases for liability under the FCA. The government has used the FCA to prosecute Medicare and other government healthcare program fraud such as coding errors, billing for services not provided, and providing care that is not medically necessary or that is substandard in quality. In addition, the government may assert that a claim including items or services resulting from a violation of the AKS or Stark Law constitutes a false or fraudulent claim for purposes of the FCA;

Table of Contents

•the Civil Monetary Penalties Law, which prohibits, among other things, an individual or entity from offering remuneration to a federal healthcare program beneficiary that the individual or entity knows or should know is likely to influence the beneficiary to order or receive healthcare items or services from a particular provider. We may also be subject to civil monetary penalties and other sanctions under the statute if we or our Network Practices hire or contract with any individuals or entities that are or become excluded from government healthcare programs, for the provision of items or services for which payment may be made under such programs;

•the criminal healthcare fraud provisions of HIPAA and related rules that prohibit knowingly and willfully executing a scheme or artifice to defraud any healthcare benefit program or falsifying, concealing or covering up a material fact or making any material false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Similar to the AKS, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it to have committed a violation;

•reassignment of payment rules that prohibit certain types of billing and collection practices in connection with claims payable by the Medicare or Medicaid programs;

•similar state law provisions pertaining to anti-kickback, self-referral and false claims issues, some of which may apply to items or services reimbursed by any payor, including patients and commercial insurers;

•laws that regulate debt collection practices;

•a provision of the Social Security Act that imposes criminal penalties on healthcare providers who fail to disclose, or refund known overpayments;

•federal and state laws that prohibit providers from billing and receiving payment from Medicare and Medicaid for services unless the services are medically necessary, adequately and accurately documented, and billed using codes that accurately reflect the type and level of services rendered;

•federal and state laws and policies that require healthcare providers to maintain licensure, certification or accreditation to enroll and participate in the Medicare and Medicaid programs, to report certain changes in their operations to the agencies that administer these programs and, in some cases, to re-enroll in these programs when changes in direct or indirect ownership occur;

•federal and state laws pertaining to the provision of services by nurse practitioners and physician assistants in certain settings, physician supervision of those services, and reimbursement requirements that depend on the types of services provided and documented and relationships between physician supervisors and nurse practitioners and physician assistants; and

•Medicare and Medicaid regulations, manual provisions, local coverage determinations, national coverage determinations and agency guidance imposing complex and extensive requirements upon healthcare providers.

The laws and regulations in these areas are complex, changing and often subject to varying interpretations. As a result, there is no guarantee that a government authority will find that we or our Network Practices are in compliance with all such laws and regulations that apply to our business. Further, because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of the business activities undertaken by us or our Network Practices could be subject to challenge under one or more of these laws, including, without limitation, patient assistance programs that waive or reduce the patient’s obligation to pay copayments, coinsurance or deductible amounts owed for the services provided to them if they meet certain financial need criteria. If we or our Network Practices’ operations are found to be in violation of any of such laws or any other governmental regulations that apply, we may be subject to significant penalties, including, without limitation, administrative, civil and criminal penalties, damages, fines, disgorgement, the curtailment or restructuring of operations, integrity oversight and reporting obligations, exclusion from participation in federal and state healthcare programs and imprisonment. In addition, any action against us or our Network Practices for violation of these laws or regulations, even if successfully defended against, could cause us to incur significant legal expenses, divert our management’s attention from the operation of our business and result in adverse publicity, or otherwise experience a material adverse impact on our business, results of operations, financial condition, cashflows, reputation as a result.

If any of our managed clinics or Network Practices lose their regulatory licenses, permits and/or accreditation status, or become ineligible to receive reimbursement under Medicare or Medicaid or other third-party Payors, there may be a material adverse effect on our business, financial condition, cash flows, or results of operations.

The operations of our managed clinics through our Network Practices are subject to extensive federal, state and local regulation relating to, among other things, the adequacy of medical care, equipment, personnel, operating policies and procedures, dispensing of prescription drugs, fire prevention, rate-setting and compliance with building codes and

Table of Contents

environmental protection. Our managed clinics and Network Practices are also subject to extensive laws and regulation relating to facility and professional licensure, conduct of operations, including financial relationships among healthcare providers, Medicare and Medicaid fraud and abuse and physician self-referrals, and maintaining updates to our Network Practices’ enrollment in the Medicare and Medicaid programs, including addition of new clinic locations, providers and other enrollment information. Our managed clinics and Network Practices are subject to periodic inspection by licensing authorities and accreditation organizations to assure their continued compliance with these various standards. There can be no assurance that these regulatory authorities will determine that all applicable requirements are fully met at any given time. Should any of our managed clinics or Network Practices be found to be noncompliant with these requirements, we or our Network Practices could be assessed fines and penalties, could be required to refund reimbursement amounts or could lose our licensure or Medicare and/or Medicaid certification or accreditation so that we or our Network Practices are unable to receive reimbursement from such programs and possibly from other third-party payors, any of which could materially adversely affect our business, financial condition, cash flows or results of operations.

If we or our Network Practices fail to comply with applicable data interoperability and information blocking rules, our consolidated results of operations could be adversely affected.

The 21st Century Cures Act (the “Cures Act”), which was signed into law in December 2016, includes provisions related to data interoperability, information blocking and patient access. In May 2020, the HHS Office of the National Coordinator for Health Information Technology, or ONC, and CMS published the Cures Act final rule, which was intended to clarify provisions of the Cures Act regarding interoperability and information blocking, and include, among other things, requirements surrounding information blocking, changes to ONC’s health IT certification program and requirements that CMS-regulated payors make relevant claims/care data and provider directory information available through standardized patient access and provider directory application programming interfaces, or APIs, that connect to provider electronic health record systems, or EHRs. The final rule will transform the way in which healthcare providers, health IT developers, health information exchanges/health information networks, or HIEs/HINs, and health plans share patient information, and create significant requirements for healthcare industry participants. For example, the final rule, which went into effect on April 5, 2021, prohibits healthcare providers, health IT developers of certified health IT, and HIEs/HINs from engaging in practices that are likely to interfere with, prevent, materially discourage, or otherwise inhibit the access, exchange or use of electronic health information, or EHI, also known as “information blocking.” To further support access and exchange of EHI, the final rule identifies eight “reasonable and necessary activities” as exceptions to information blocking activities, as long as specific conditions are met. Any failure to comply with these rules could have a material adverse effect on our business, results of operations and financial condition.

Actual or perceived failures to comply with applicable data protection, privacy and security, advertising and consumer protection laws, regulations, standards and other requirements could adversely affect our business, financial condition and results of operations.

We and our Network Practices collect, receive, generate, use, process, and store significant and increasing volumes of sensitive information, such as employee, individually identifiable health information and other personally identifiable information. We and our Network Practices are subject to a variety of federal and state laws and regulations, as well as contractual obligations, relating to the collection, use, storage, retention, security, disclosure, transfer, return, destruction and other processing of personal information, including health-related information. Enforcement actions and consequences for noncompliance with such laws, directives and regulations are rising, and the regulatory framework for privacy, data protection and data transfers is complex and rapidly evolving and is likely to remain uncertain for the foreseeable future.

In the United States, numerous such federal and state laws and regulations, including data breach notification laws, health information privacy laws, and consumer protection laws and regulations, including those that govern the collection, use, disclosure, and protection of health-related and other personal information, could apply to our operations or the operations of our Network Practices. For example, the Health Insurance Portability and Accountability Act of 1996, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and regulations implemented thereunder, which we refer to collectively as HIPAA, imposes privacy, security and breach notification obligations on certain health care providers, health plans, and health care clearinghouses, known as covered entities, as well as business associates that perform certain services that involve creating, receiving, maintaining or transmitting individually identifiable health information for or on behalf of such covered entities. HIPAA requires covered entities, such as our Network Practices, and business associates, such as us, to develop and maintain policies with respect to the protection of, use and disclosure of protected health information, or PHI, including the adoption of administrative, physical and technical safeguards to protect such information, and certain notification requirements in the event of a data breach.

Table of Contents

Entities that are found to be in violation of HIPAA as the result of a breach of unsecured PHI, a complaint about privacy practices or an audit by HHS, may be subject to significant civil, criminal and administrative fines and penalties and/or additional reporting and oversight obligations if required to enter into a resolution agreement and corrective action plan with HHS to settle allegations of HIPAA non-compliance. HIPAA also authorizes state Attorneys General to file suit on behalf of their residents. Courts may award damages, costs and attorneys’ fees related to violations of HIPAA in such cases. While HIPAA does not create a private right of action allowing individuals to sue us in civil court for violations of HIPAA, its standards have been used as the basis for duty of care in state civil suits such as those for negligence or recklessness in the misuse or breach of PHI. Enforcement actions by HHS or state Attorneys General could result in significant financial liability and reputational harm, in addition to depleting financial resources.

Numerous other state and federal laws, including consumer protection laws and regulations, govern the collection, dissemination, use, access to, confidentiality, security and processing of personal information, including health-related information, some of which are more stringent than HIPAA and many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts. In addition, these laws and regulations in many cases are more restrictive than, and may not be preempted by, HIPAA and may be subject to varying interpretations by courts and government agencies.

Laws in all 50 states and other United States territories have been enacted that may require businesses to provide notice to regulators or to individuals whose personal information has been accessed without authorization or disclosed as a result of a data breach. Such laws are not always consistent, and compliance in the event of a widespread data breach is costly and may be challenging. We also may be contractually required to comply with various requirements relating to privacy and security of personal information and to provide notice or take other actions in connection with a data breach, and failures to comply with such contractual requirements could result in potential contractual liability. Although we may have certain contractual protections in our contracts with third parties, such contractual protections may not be sufficient to adequately protect us from potential liability, potential harm to our reputation or the need to expend significant resources on data security and responding to an actual or perceived data breach.

States are also constantly amending existing laws, requiring attention to frequently changing requirements, and we expect these changes to continue. For example, in June 2018, California enacted the California Consumer Privacy Act, or the CCPA, which became effective on January 1, 2020, and, among other things, requires covered companies to provide disclosures to California consumers, and affords such consumers certain data protection rights, including the ability to opt-out of certain sales of personal information. The CCPA provides for civil penalties for violations, as well as a private right of action for certain data breaches that result in the loss of personal information that may increase data breach litigation. While the CCPA includes certain exceptions for health-related information, including PHI, it still may require us to modify our data practices and policies and to incur substantial costs and expenses in an effort to comply. Further, the California Privacy Rights Act, or CPRA, recently passed in California. The CPRA will impose additional data protection obligations on covered businesses, including additional consumer rights processes, limitations on data uses, new audit requirements for higher risk data, and opt outs for certain uses of sensitive data. It will also create a new California data protection agency authorized to issue substantive regulations and could result in increased privacy and information security enforcement. The majority of the provisions went into effect on January 1, 2023, and additional compliance investment and potential business process changes may be required.

As required by certain laws, we publicly post documentation regarding our privacy practices concerning the collection, processing, use and disclosure of certain data. The publication of our privacy policy and other documentation that provide promises and assurances about privacy and security can subject us to potential state and federal action if they are found to be deceptive, unfair, or misrepresentative of our actual practices. In addition, although we endeavor to comply with our published policies and documentation, individuals could allege we have failed to do so, or we may at times actually fail to do so despite our efforts. Any failure by us, our third-party service providers or other parties with whom we do business to comply with this documentation or with laws or regulations applicable to our business could result in proceedings against us by governmental entities or others.

In addition, the Federal Trade Commission, or the FTC, expects a company’s data security measures to be reasonable and appropriate in light of the sensitivity and volume of consumer information it holds, the size and complexity of its business, and the cost of available tools to improve security and reduce vulnerabilities. Our failure to take any steps perceived by the FTC as appropriate to protect consumers’ personal information may result in claims by the FTC that we have engaged in unfair or deceptive acts or practices in violation of Section 5(a) of the FTC Act. State consumer protection laws provide similar causes of action for unfair or deceptive practices for alleged privacy, data protection and data security violations.

In addition to government regulation, privacy advocates and industry groups may propose self- regulatory standards from time to time. These and other industry standards may legally or contractually apply to us, or we may elect to comply with such standards or to facilitate our customers’ compliance with such standards. We expect that there will continue to be new proposed laws and regulations concerning privacy, data protection, and information security, and we cannot yet determine the impact such future laws, regulations, and standards may have on our business. New laws, amendments to or re-interpretations of existing laws and regulations, industry standards, contractual and other obligations may require us to incur additional costs and restrict our business operations. Because the interpretation and application of laws, standards, contractual and other obligations relating to privacy and data protection are still uncertain and changing, it is possible that these laws, standards, contractual and other obligations may be interpreted and applied in a manner that is inconsistent with our data management practices, our privacy, data protection or data security policies or procedures or the features of our technology. If so, in addition to the possibility of fines, lawsuits, regulatory investigations, imprisonment of company officials and public censure, other claims and penalties, significant costs for remediation and damage to our reputation, we could be required to fundamentally change our business activities and practices or modify our technology, any of which could adversely affect our business. We may be unable to make such changes or modifications in a commercially reasonable manner, or at all, and our ability to develop new software or provide new services could be limited. Any inability to adequately address privacy, data protection or information security-related concerns, even if such concerns are unfounded, or to successfully negotiate privacy, data protection or information security- related contractual terms with customers, or to comply with applicable laws and regulations, or our policies relating to privacy, data protection, and information security, could result in additional cost and liability to us, harm our reputation and brand, and adversely affect our business, financial condition and results of operations.

We and our Network Practices are subject to federal, state and local laws and regulations that govern our business. These include regulations of our employment practices, including minimum wage, living wage, and paid time-off requirements, permitting and licensing, employee health and safety and the storage, treatment and disposal of waste. Failure to comply with these laws and regulations, or changes to these laws and regulations that increase our expenses, could adversely impact our operations.

We and our Network Practices are required to comply with all applicable federal, state and local laws and regulations related to the operation of our business. These regulations include regulations governing our Network Practices’ dispensary services, the construction, the use of our managed clinics and the treatment of hazardous waste or drug products. Changes in regulations or new regulations could increase our costs, cause our Network Practices to lose licenses or accreditations or otherwise harm our business or the business of our Network Practices.

We and our Network Practices are required to comply with all applicable federal, state and local laws and regulations relating to employment, including occupational safety and health requirements, wage and hour and other compensation requirements, employee benefits, providing leave and sick pay, employment insurance, proper classification of workers as employees or independent contractors, immigration and equal employment opportunity laws. These laws and regulations can vary significantly among jurisdictions and can be highly technical. Costs and expenses related to these requirements are a significant operating expense and may increase as a result of, among other things, changes in federal, state or local laws or regulations, or the interpretation thereof, requiring employers to provide specified benefits or rights to employees, increases in the minimum wage and local living wage ordinances, increases in the level of existing benefits or the lengthening of periods for which unemployment benefits are available. We may not be able to offset any increased costs and expenses. Furthermore, any failure to comply with these laws requirements, including even a seemingly minor infraction, can result in significant penalties which could harm our reputation and have a material adverse effect on our business.

Future changes to applicable tax laws and regulations and/or their interpretation may have an adverse effect on our business, financial condition and results of operations. Tax rules and regulations are subject to interpretation and require judgment by us that may be successfully challenged by the applicable taxation authorities upon audit, which could result in additional tax liabilities.

Changes in tax laws or their interpretation could decrease the amount of revenues we receive, the value of any tax loss carry-forwards and tax credits recorded on our balance sheet and the amount of our cash flow, and adversely affect our business, financial condition or results of operations. In addition, other factors or events, including business combinations and investment transactions, changes in the valuation of our deferred tax assets and liabilities, adjustments to taxes upon finalization of various tax returns or as a result of deficiencies asserted by taxing authorities, increases in expenses not

Table of Contents

deductible for tax purposes, changes in available tax credits, other changes in the apportionment of our income, and changes in tax rates, could also increase our future effective tax rate.

In addition, our effective tax rate and tax liability are based on the application of current income tax laws, regulations and treaties. These laws, regulations and treaties are complex, and the manner which they apply to us and our diverse set of business arrangements is often open to interpretation, and can require us to take positions regarding the interpretation of applicable rules or the valuation of our assets that are subject to material uncertainty. Significant management judgment is required in determining our provision for taxes, our deferred tax assets and liabilities and any valuation allowance recorded against our net deferred tax assets. The proper tax treatment or characterization of the transactions we undertake is often subject to significant uncertainty, and the resolution of any related issues could affect the withholding tax liabilities to which we are subject or the tax deductions that we are able to claim. The tax authorities could challenge our interpretation of laws, regulations and treaties or the positions that we have taken regarding the valuation of our assets, resulting in additional tax liability or adjustment to our income tax provision.

Our tax filings are subject to review or audit by various taxing authorities. As discussed above, we exercise significant judgment in determining our provision for taxes and, in the ordinary course of our business, there may be transactions and calculations where the proper tax treatment is uncertain. We may also be liable for taxes in connection with businesses we acquire. Our determinations are not binding on the IRS or any other taxing authorities, and accordingly the final determination in an audit or other proceeding may be materially different than the treatment reflected in our tax provisions, accruals and returns. An assessment of additional taxes because of an audit could have a material adverse effect on our business, financial condition, results of operations and cash flows.

New income, sales, use or other tax laws, statutes, rules, regulations or ordinances could be enacted at any time, or interpreted, changed, modified or applied adversely to us, any of which could adversely affect our business operations and financial performance. We are unable to predict what changes will occur and, if so, the ultimate impact on its business. To the extent that such changes have a negative impact on us, they may materially and adversely impact its business, financial condition, results of operations and cash flows.

Risks Related to Operating as a Public Company

The requirements of being a public company, including maintaining adequate internal control over our financial and management systems, may strain our resources, divert management’s attention, make us incur increased costs, and affect our ability to attract and retain executive management and qualified board members.

As a public company we will incur significant legal, accounting, and other expenses that we did not incur as a private company. We are subject to reporting requirements of the Exchange Act, the Sarbanes-Oxley Act, the rules subsequently implemented by the SEC, the rules and regulations of the listing standards of Nasdaq and other applicable securities rules and regulations. Stockholder activism, the current political and social environment, and the current high level of government intervention and regulatory reform may lead to substantial new regulations and disclosure obligations, which will likely result in additional compliance costs and could impact the manner in which we operate our business in ways we cannot currently anticipate.

Our management team has limited experience managing a publicly traded company, interacting with public company investors, and complying with the increasingly complex laws pertaining to public companies. Our management team may not successfully or efficiently manage our transition to being a public company subject to significant regulatory oversight and reporting obligations under the federal securities laws and the continuous scrutiny of securities analysts and investors. These new obligations and constituents will require significant attention from our senior management and could divert their attention away from the day-to-day management of our business, which could adversely affect our business, financial condition and results of operations. Although we have already hired additional employees to assist us in complying with these requirements, our finance team is small and we may need to hire more employees in the future, or engage outside consultants, which will increase our operating expenses. We also expect that being a public company and complying with applicable rules and regulations will make it more expensive for us to obtain director and officer liability insurance, and we may be required to incur substantially higher costs to obtain and maintain the same or similar coverage. These factors could also make it more difficult for us to attract and retain qualified members of our board of directors and qualified executive officers.

Compliance with these rules and regulations may strain our financial and management systems, internal controls, and employees. The Exchange Act requires, among other things, that we file annual, quarterly, and current reports with respect

Table of Contents

to our business and operating results. Moreover, the Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures, and internal control, over financial reporting. In order to maintain and, if required, improve our disclosure controls and procedures, and internal control over, financial reporting to meet this standard, significant resources and management oversight may be required. If we encounter additional material weaknesses or deficiencies in our internal control over financial reporting, we may not detect errors on a timely basis and our consolidated financial statements may be materially misstated. Effective internal control is necessary for us to produce reliable financial reports and is important to prevent fraud.

As a public company listed in the United States, we will incur significant additional legal, accounting and other costs. These additional costs could negatively affect our financial results. In addition, changing laws, regulations and standards relating to corporate governance and public disclosure, including regulations implemented by the SEC and Nasdaq, may increase legal and financial compliance costs and make some activities more time- consuming. These laws, regulations and standards are subject to varying interpretations and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. We intend to invest resources to comply with evolving laws, regulations and standards, and this investment may result in increased general and administrative expenses and a diversion of management’s time and attention from revenue-generating activities to compliance activities. If, notwithstanding our efforts to comply with new laws, regulations and standards, we fail to comply, regulatory authorities may initiate legal proceedings against us and our business may be harmed.

Due to our annual gross revenues exceeding $1.235 billion in 2023, we lost our eligibility to qualify as an emerging growth company. Although we lost our eligibility to qualify as an emerging growth company, our independent registered public accounting firm will not be required to formally attest to the effectiveness of our internal control over financial reporting in this Annual Report on Form 10-K because we are exempt from such requirement as a non-accelerated filer. If we lose our eligibility to qualify as a non-accelerated filer as of the next measurement date of June 30, 2024, we expect that, for the annual report on Form 10-K for the fiscal year ending December 31, 2024, our independent registered public accounting firm will be required to formally attest to the effectiveness of our internal control over financial reporting. As a result, we expect to incur significant expenses and devote substantial management effort toward ensuring compliance with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act. Despite our efforts, there is a risk that we will not be able to conclude, within the prescribed timeframe or at all, that our internal control over financial reporting is effective as required by Section 404. If we are not able to timely and effectively remediate the material weaknesses described above in this section, or if we identify one or more additional material weaknesses, it could result in an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements. As a result, the market price of our common stock could be negatively affected, and we could become subject to investigations by Nasdaq, the SEC or other regulatory authorities, which could require additional financial and management resources.

Failure to comply with these rules might also make it more difficult for us to obtain some types of insurance, including director and officer liability insurance, and we might be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. The impact of these events could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, on committees of our board of directors or as members of senior management.

The trading price of our Class A Common Stock may be volatile, and purchasers of our Class A Common Stock could incur substantial losses.

The trading price of our Class A Common Stock may be volatile. The stock market in general has experienced extreme volatility that has often been unrelated to the operating performance of particular companies. As a result of this volatility, investors may not be able to sell their common stock at or above the price paid for the shares. The market price for our Class A Common Stock may be influenced by many factors, including:

•actual or anticipated variations in our operating results;

•changes in financial estimates by us or by any securities analysts who might cover our shares;

•conditions or trends in our industry;

•changes as a result of the COVID-19 pandemic, international hostilities or similar macroeconomic events;

•unfavorable general economic conditions, such as a recession or economic slowdown;

•stock market price and volume fluctuations of comparable companies;

•announcements by us or our competitors of new product or service offerings, significant acquisitions, strategic partnerships, or divestitures;

Table of Contents

•announcements of investigations or regulatory scrutiny of our operations or lawsuits filed against us;

•capital commitments;

•investors’ general perception of us and our business;

•recruitment or departure of key personnel; and

•sales of our common stock, including sales by our directors and officers or specific stockholders.

In addition, in the past, stockholders have initiated class action lawsuits following periods of volatility in the market prices of these companies’ stock. Such litigation, if instituted against us, could cause us to incur substantial costs and divert management’s attention and resources from our business.

Anti-takeover provisions in our organizational documents could delay or prevent a change of control.

Certain provisions of our Charter and Bylaws contain an anti-takeover effect and may delay, defer or prevent a merger, acquisition, tender offer, takeover attempt or other change of control transaction that a stockholder might consider in its best interest, including those attempts that might result in a premium over the market price for the shares held by our stockholders. These provisions provide for, among other things:

•the division of our Board into three classes of directors, with each class serving a staggered three year term;

•there is no cumulative voting with respect to the election of our Board;

•the ability of our Board to issue one or more series of preferred stock;

•advance notice for nominations of directors by stockholders and for stockholders to include matters to be considered at our annual meetings;

•limiting the ability of stockholders to call special stockholder meetings;

•limiting the ability of stockholders to act by written consent;

•the ability of our Board to exclusively fill a vacancy created by the expansion of our Board or the resignation, death or removal of a director in certain circumstances;

•providing that our Board is expressly authorized to adopt, amend, alter or repeal our bylaws;

•providing that stockholders may amend the bylaws only by the affirmative vote of at least 66.7% of the voting power of all then outstanding shares of capital stock of AON entitled to vote generally in the election of directors, voting together as a single class; and

•AON is subject to the provisions of Section 203 of Delaware General Corporation Law (“DGCL”).

These anti-takeover provisions could make it more difficult for a third party to acquire us, even if the third party’s offer may be considered beneficial by many of our stockholders. As a result, our stockholders may be limited in their ability to obtain a premium for their shares. These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors of your choosing and to cause us to take other corporate actions you desire. See “Description of Securities.”

Our Charter designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or stockholders.

Our charter provides that, subject to limited exceptions, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for any (i) derivative action or proceeding brought on behalf of us, (ii) action asserting a claim of breach of a duty (including any fiduciary duty) owed by any current or former director, officer, stockholder, employee or agent of the Company to us or our stockholders, (iii) action asserting out of or relating to any provision of the DGCL, the Charter or the Bylaws or (iv) action asserting a claim governed by the internal affairs doctrine of the State of Delaware shall, to the fullest extent permitted by law. Our charter will also provide that, to the fullest extent permitted by law, the federal district courts of the United States will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. Any person or entity purchasing, otherwise acquiring or holding any interest in shares of our capital stock shall be deemed to have notice of and to have consented to the provisions of the provisions of the Charter described above. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers and employees. This exclusive forum provision will not apply to claims under the Exchange Act, but will apply to actions arising under the Securities Act. Section 22 of the Securities Act,

Table of Contents

however, creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder.

Accordingly, there is uncertainty as to whether a court would enforce such a forum selection provision as written in connection with claims arising under the Securities Act, and investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. If a court were to find these provisions of the Charter inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business and financial condition.

Risks Relating to Our Common Stock and Warrants

We were obligated to register for resale a substantial amount of our securities in the public market (including the shares of Class A Common Stock issuable upon exercise of our warrants, conversion of our Class B Common Stock, or conversion of our Series A Preferred Stock), and the future resale of such securities or the perception that such sales may occur, may cause the market price of our securities to decline significantly.

We were obligated to register for resale a substantial amount of our securities in the public market and such securities represent approximately 536% of total AON Class A Common Stock outstanding as of March 26, 2024. The amount of Class A Common Stock offered for resale exceeds the number of shares of Class A Common Stock currently outstanding because a significant portion of the shares of Class A Common Stock registered and offered for resale is not currently outstanding and are issuable upon the exercise of warrants, conversion of our Class B Common Stock, or conversion of our Series A Preferred Stock. The sale of these securities in the public market, or the perception that holders of a large number of securities intend to sell their securities, could reduce the market price of our Class A Common Stock and public warrants.

As of March 20, 2024, lock-up restrictions with respect to the AON LLC equity stockholders for whom 28,109,796 shares are registered for resale, have expired, and AON LLC equity holders may convert their AON LLC common units and Class B Common Stock for up to an aggregate of 28,109,796 shares of Class A Common Stock. Furthermore, the Sponsors and its permitted transferees for whom 14,450,833 shares are registered for resale, are currently prohibited from transferring its shares of Class A Common Stock for a period of 12 months following the Closing Date. The market price of our Class A Common Stock could decline if the holders of our Class A Common Stock sell such shares or are perceived by the market as intending to sell them.

Certain existing stockholders purchased our shares at a price below the current trading price of such shares, and may experience a positive rate of return based on the current trading price. Other investors and stockholders may not experience a similar rate of return.

The Sponsor paid the nominal price of $0.003 per share for the shares of Class A Common Stock held by it and $1.50 per private placement warrant as of March 12, 2021. The shares held by the Sponsor and its permitted transferees (including 2,839,375 Earnout Shares, which are subject to vesting) represent approximately 87% of the total outstanding shares of the Company’s Class A Common Stock. If the Sponsor exercised its 6,113,333 private placement warrants, the Sponsor would own an aggregate of 14,450,833 shares of our Class A Common Stock, or approximately 92% of our outstanding Class A Common Stock. As a result of these nominal prices compared with the market prices of our Class A Common Stock and public warrants, which as of March 26, 2024, were $5.97 per share and $0.39 per warrant, respectively, the Sponsor is likely to earn a positive return on its investment even if other holders of shares of Class A Common Stock, including our public stockholders, experience a negative return on their investment in the Company’s securities. Based on the closing price as of March 26, 2024 of $5.97 per share, the Sponsor and its permitted transferees could earn a profit of $49.8 million (assuming full vesting of the Earnout Shares). Based on the closing price of $0.39 per warrant, the Sponsor and its permitted transferees will not earn a profit on the sale of the private placement warrants, but if the trading price of the warrant exceeds the $1.50 price that the Sponsor paid for the private placement warrants, the Sponsors and its permitted transferees may realize a profit. As a result, the market price of our Class A Common Stock may be depressed because the Sponsor paid approximately $0.003 per share for its Founder Shares. The Sponsor and its permitted transferees may be incentivized to sell its securities when others are not. Other stockholders and investors may not experience a similar rate of return.

Because we do not anticipate paying any cash dividends in the foreseeable future, capital appreciation, if any, would be your sole source of gain.

Table of Contents

We currently anticipate that we will retain future earnings for the development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. As a result, capital appreciation, if any, of Class A Common Stock would be your sole source of gain on an investment in such shares for the foreseeable future.

A market for our securities may not continue, which would adversely affect the liquidity and price of its securities.

The price of our securities may continue to fluctuate significantly. An active trading market for our securities may never develop or, if developed, it may not be sustained. In addition, the price of our securities can vary due to general economic conditions and forecasts, our general business condition and the release of our financial reports. Additionally, if our securities are not listed on, or become delisted from Nasdaq for any reason, and are quoted on the OTC Bulletin Board, an inter-dealer automated quotation system for equity securities that is not a national securities exchange, the liquidity and price of our securities may be more limited than if we were quoted or listed on Nasdaq or another national securities exchange. You may be unable to sell your securities unless a market can be established or sustained.

Nasdaq may delist our securities from trading on its exchange, which could limit investors’ ability to make transactions in its securities and subject us to additional trading restrictions.

Currently, Class A Common Stock and public warrants are listed on Nasdaq under the symbols “AONC” and “AONCW.” In order to continue the list of these securities on Nasdaq, we are required to maintain certain financial, distribution and stock price levels. Generally, we are required to maintain a public float of $500,000, a minimum market capitalization of $1,000,000 and a minimum number of holders of our securities (generally 300 round lot stockholders). If Nasdaq delists our securities from trading on its exchange and we are not able to list its securities on another national securities exchange, we expect our securities could be quoted on an over-the-counter market. If this were to occur, we could face significant material adverse consequences, including:

•a limited availability of market quotations for our securities;

•reduced liquidity for our securities;

•a determination that Class A Common Stock is a “penny stock” which will require brokers trading in Class A Common Stock to adhere to more stringent rules and possibly result in a reduced level of trading activity in the secondary trading market for our securities;

•a limited amount of news and analyst coverage; and

•a decreased ability to issue additional securities or obtain additional financing in the future.

The National Securities Markets Improvement Act of 1996, which is a federal statute, prevents or preempts the states from regulating the sale of certain securities, which are referred to as “covered securities.” Since Class A Common Stock and public warrants are listed on Nasdaq, they are covered securities. However, if our securities were no longer listed on Nasdaq, they would not be covered securities and we would be subject to regulation in each state in which we offer our securities.

Our warrants may never be in the money, and they may expire worthless.

The exercise price for our public warrants is $11.50 per share, and the exercise price for our private placement warrants is $11.50 per share (each as subject to adjustment as described herein), which exceeds the market price of Class A Common Stock, which was $5.97 per share based on the closing price of Class A Common Stock on Nasdaq on March 26, 2024. If all of our public warrants were exercised in full for cash, we would receive an aggregate of approximately $95.9 million. If all of our public warrants and private placement warrants were exercised in full for cash, we would receive an aggregate of approximately $166.2 million. We do not expect warrant holders to exercise their warrants and, therefore, we do not expect to receive cash proceeds from any such exercise, for so long as the warrants remain out-of-the money. There can be no assurance that the public warrants will ever be in the money prior to their expiration and, as such, the warrants may expire worthless.

We may redeem unexpired public warrants prior to their exercise at a time that is disadvantageous to the warrant holders, thereby making the warrants worthless.

We may redeem outstanding warrants (excluding any private placement warrants held by the Sponsor or its permitted transferees) at any time after they become exercisable and prior to their expiration, at $0.01 per warrant, provided that the

Table of Contents

last reported sales price (or the closing bid price of Class A Common Stock in the event Class A Common Stock is not traded on any specific trading day) of Class A Common Stock equals or exceeds $18.00 per-share for any 20 trading days within a 30 trading-day period ending on the third business day prior to the date we send proper notice of such redemption, provided that on the date we give notice of redemption and during the entire period thereafter until the time we redeem the warrants, there is an effective registration statement under the Securities Act covering the shares of Class A Common Stock issuable upon exercise of the warrants and a current prospectus relating to them is available. We also have the ability to redeem outstanding warrants (excluding any private placement warrants held by the Sponsor or its permitted transferees) at any time after they become exercisable and prior to their expiration, at $0.10; provided that (i) the last reported sales price of the Class A Common Stock equals or exceeds $10.00 per share (as adjusted for stock splits, stock dividends, reorganizations and the like) on each of 20 trading days within the 30 trading-day period ending on the third business day prior to the date on which AON sends proper notice of such redemption and (ii) if the last reported sales price of the Class A Common Stock is less than $18.00 per share, the Private Placement Warrants are also concurrently exchanged at the same price (equal to a number of shares of Class A Common Stock) as the outstanding Public Warrants; provided that on the date AON gives notice of redemption and during the entire period thereafter until the time AON redeems the warrants, AON has an effective registration statement under the Securities Act covering the shares of Class A Common Stock issuable upon exercise of the warrants and a current prospectus relating to them is available. If and when the warrants become redeemable by us, we may exercise our redemption right even if we are unable to register or qualify the underlying securities for sale under all applicable state securities laws. Redemption of the outstanding warrants could force a warrant holder: (i) to exercise its warrants and pay the exercise price therefore at a time when it may be disadvantageous for it to do so, (ii) to sell its warrants at the then-current market price when it might otherwise wish to hold its warrants or (iii) to accept the nominal redemption price which, at the time the outstanding warrants are called for redemption, will be substantially less than the market value of its warrants.

Warrants to purchase AON Class A Common Stock are exercisable, which could increase the number of shares eligible for future resale in the public market and result in dilution to its stockholders.

We have 8,337,500 public warrants and 6,113,333 private placement warrants outstanding, all of which are currently exercisable. Each public warrant entitles its holder to purchase one share of Common Stock at an exercise price of $11.50 per share, and each private placement warrant entitles its holder to purchase one share of Common Stock at an exercise price of $11.50 per share (subject to adjustment as described herein). To the extent warrants are exercised, additional shares of Common Stock will be issued, which will result in dilution to our then existing stockholders and increase the number of shares eligible for resale in the public market. Sales of substantial numbers of such shares in the public market could depress the market price of Class A Common Stock.

Future offerings of debt or offerings or issuances of equity securities by us may adversely affect the market price of Class A Common Stock or otherwise dilute all other stockholders.

In the future, we may attempt to obtain financing or to further increase our capital resources by issuing additional shares of our Class A Common Stock or offering debt or other equity securities, including commercial paper, medium-term notes, senior or subordinated notes, debt securities convertible into equity or shares of preferred stock. We also expect to grant equity awards to employees, directors, and consultants under our stock incentive plans.

Future acquisitions could require substantial additional capital in excess of cash from operations. We would expect to obtain the capital required for acquisitions through a combination of additional issuances of equity, corporate indebtedness and/or cash from operations.

Issuing additional shares of common stock or other equity securities or securities convertible into equity may dilute the economic and voting rights of our existing stockholders or reduce the market price of our Class A Common Stock or both. Upon liquidation, holders of such debt securities and preferred shares, if issued, and lenders with respect to other borrowings would receive a distribution of our available assets prior to the holders of our Class A Common Stock. Debt securities convertible into equity could be subject to adjustments in the conversion ratio pursuant to which certain events may increase the number of equity securities issuable upon conversion. Preferred shares, if issued, could have a preference with respect to liquidating distributions or a preference with respect to dividend payments that could limit our ability to pay dividends to the holders of the Class A Common Stock. Our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, which may adversely affect the amount, timing and nature of our future offerings.

Table of Contents

The price of Class A Common Stock could decline if securities analysts do not publish research or if securities analysts or other third parties publish inaccurate or unfavorable research about us.

The trading market for Class A Common Stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. We do not currently have and may never obtain research coverage by securities and industry analysts. If no or few securities or industry analysts commence coverage of us, the trading price for Class A Common Stock could be negatively impacted. In the event we obtain securities or industry analyst coverage, if any of the analysts who cover us issue an adverse or misleading opinion regarding us, our business model or the performance of Class A Common Stock, or if our results of operations fail to meet the expectations of analysts, the price of Class A Common Stock would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our share price or trading volume to decline.

We may be subject to securities litigation, which is expensive and could divert management’s attention.

The share price of our Class A Common Stock may be volatile and, in the past, companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. AON may be the target of this type of litigation in the future. Litigation of this type could result in substantial costs and diversion of management’s attention and resources, which could have a material adverse effect on its business, financial condition, results of operations and prospects. Any adverse determination in litigation could also subject us to significant liabilities.

Item 1C. Cybersecurity

Risk Management and Strategy

AON has developed a standardized and systematic process for identifying, assessing, and mitigating cybersecurity risks within the organization. The process includes the gathering of information on cybersecurity trends, assessing risks, and recommending mitigation actions for periodic reporting to boards or committees. The documented standard operating procedure (“SOP”) outlines the processes, responsibilities, and methodologies that the Company follows to proactively manage and mitigate risks associated with the confidentiality, integrity, and availability of sensitive organizational and healthcare information.

The SOP includes guidelines for risk identification and information gathering, consistent with the National Institute of Standards and Technology Cybersecurity Framework (“NIST CSF”), risk assessment, mitigation planning and recommendation, executive board and committee reporting, and documentation and review. The SOP also identifies the roles and responsibilities of individuals and groups within the organization that participate in ensuring that risks are identified, assessed, and mitigated in a way that aligns with organizational goals, risk appetite, legal requirements, and best practices.

The SOP is required to be approved by the Information Security Review Board (“ISRB”) as well as our SEC Reporting Manager and reviewed every 2 years for relevance and effectiveness.

AON has implemented a risk-based approach to identify and assess cybersecurity threats (both internal and external) that could affect our operations (including, but not limited to, our mission, functions, image, or reputation), assets, information, and individuals. This approach incorporates both external and internal risk and threat identification methodologies.

External: AON engages in penetration testing and external trend analysis, which primarily monitors industry reports, threat intelligence feeds, and cybersecurity news sources for potential risks and emerging threats/trends relevant to the organization.

Internal: AON’s internal risk and threat identification includes the conducting of real-time monitoring of the AON data communications systems, transactions, and event logs on a 24x7 basis. We also conduct periodic security risk identification exercises including regulatory compliance assessments, vulnerability scanning and penetration testing to identify potential

Table of Contents

risks and threats. Finally, we periodically conduct cybersecurity awareness training for all users and continuously encourage/remind them to report any identified threats or potential risks.

Identified risks are documented in a risk register or security gap remediation worksheet with detailed information and an expert opinion on their probability of occurrence and potential impact. These values are then used to determine the overall rating value of the risk.

There are several major risk categories that AON takes into consideration when identifying risks. The major risk categories that AON recognizes include: “Advanced Persistent Threat” (“APT”), “Denial of Service” (“DoS”), “Equipment Loss or Theft”, “Inappropriate Use or Unlawful Activity”, “Malware/Ransomware”, “Phishing/Smishing/Vishing”, “Supply Chain/Vendor Incident”, “Unauthorized Access or Privacy Breach”, and “Unplanned Downtime/Outage”.

AON also strives to categorize organizational data based on sensitivity levels. AON’s data is classified into one of the following categories: “Restricted/Confidential,” “Private/Internal,” or “Public”. These data categories are taken into consideration and aligned with potential risks and impact assessments.

AON's risk management team is charged with the responsibility of ensuring that the processes described above are implemented according to the company's risk management policy and that they align with the organization's stated risk appetite and tolerance levels. AON's risk management policy dictates that the company shall identify, assess, and manage material risks and craft a risk response strategy to address each individual case of an identified risk.

AON engages third parties in various stages of the risk management process. These third parties include a virtual chief security officer service (“vCISO”), which is engaged as needed, and an incident response team associated with our managed detection and response service.

AON has established a comprehensive vendor management program to assess, monitor, and manage risks associated with all third-party vendors including cybersecurity service providers. Thorough due diligence is exercised when selecting cybersecurity vendors including the evaluation of the provider's reputation, experience, certifications (where applicable), and adherence to industry best practices. The evaluation process includes the review of “Business Associate and Information Security Questionnaires” as well as the company's “Service/System Organization Controls” (“SOC”) report, and these must be reviewed annually. Clear cybersecurity expectations and requirements are required to be defined in contractual agreements, as well as clauses related to data protection, incident response, reporting, and compliance with security standards. Vendors must comply with all applicable AON policies, practice standards and agreements, including, but not limited to: non-disclosure agreements, code of conduct and safety policies, privacy and security policies, auditing policies, and software licensing policies.

Governance

AON has defined multiple roles and responsibilities to create a collaborative and effective approach to cybersecurity risk management. Each plays a critical part in ensuring that risks are identified, assessed, and mitigated in a way that aligns with organizational goals, risk appetite, legal requirements, and best practices. The collaboration between these roles ensures a comprehensive and well-coordinated effort to protect the organization from cybersecurity threats.

Business Owner / Data Stewardship - Has responsibility for specific business processes or data sets. Ensures that data is used, stored, and transmitted securely.

Chief Information Security Officer (CISO) / Chief Information Officer (CIO) - Provides overall leadership for the information security program. Represents cybersecurity interests at the executive level.

Compliance Officer - Ensures that the organization complies with relevant laws and regulations. Provides guidance on compliance requirements impacting cybersecurity.

IT Security Team / Information Security Practitioners - Acts as point of contact for risk-related concerns within respective teams. Implements security measures based on risk assessments.

Risk Officer - Facilitates and coordinates risk management activities. Ensures that the risk management process is followed consistently.

Risk Management Committee - Provides expertise in various domains of cybersecurity. Ensures the overall effectiveness of risk management processes. This is an informal management committee that was initiated by the IT Security Director. Members include the CIO, CISO, Risk Officer, and Compliance Officer. Members were selected based on their existing roles within AON and their relationship to cybersecurity and risk management functions.

The AON Risk Management Committee meets on a quarterly cadence to summarize cybersecurity trends, identified risks, and mitigation strategies. The committee works together to craft executive-level reports suitable for board or committee review. It is the responsibility of the CIO, CISO, or the Risk Officer, each of whom have at least 10 years of expertise in the cybersecurity field, to present key findings, risk assessments, and mitigation strategies to boards or committees, including the Information Security Review and Executive Boards. The AON Risk Management Committee reviews and summarizes key cybersecurity trends, identified risks, and mitigation strategies and crafts executive-level reports for AON's leadership. It is the responsibility of the CIO, CISO, or the Risk Officer to present these reports to boards or committees, including the Information Security Review and Executive Boards on a regular cadence.

It is the responsibility of our board of directors to establish and maintain a robust cybersecurity risk governance framework within the organization. The board of directors is also responsible for defining and communicating our organizational risk appetite and tolerance for cybersecurity. Additionally, the board of directors provides input and oversight of the organization's cybersecurity strategy and objectives and ensures alignment between cybersecurity initiatives and overall business goals.

AON’s board of directors is required to actively participate in risk identification workshops and crisis management planning, especially regarding cybersecurity incidents. The board of directors is also responsible for promoting a cybersecurity-aware and continuous improvement culture within the organization. Starting in 2024, AON’s board of directors will receive quarterly reports on the organization's cybersecurity posture, including risk findings and assessments, mitigation strategies, and key performance indicators (“KPIs”), which shall be presented in a review meeting by representative from the Risk Management Committee.

Material Effects of Cybersecurity Threats

There is a vast array of potential material effects that AON could feasibly face from cybersecurity threats in the near future. While we have identified the most likely of these in our “Cybersecurity Incident Response Plan and Risk Management, Assessment and Mitigation Guide,” and have either taken proactive measures and/or created a response strategy to mitigate the likelihood and impact of each, there remains a distinct possibility that a new/emerging threat might impact the business. The most likely material effects that could impact the organization in the near future include:

Business Disruption: Cybersecurity threats, such as malware or ransomware attacks or DoS attacks, which could lead to business disruptions. Unplanned downtimes or outages, particularly in critical systems or services, may impact the organization's ability to operate efficiently, affecting business continuity.

Supply Chain Disruptions: Cybersecurity threats targeting third-party vendors or supply chain partners may lead to disruptions. Dependencies on external entities could impact the organization's ability to deliver services, affecting business strategy and financial conditions.

Increased Operational Costs: Investing in cybersecurity measures, incident response, and recovery efforts may lead to increased operational costs. More importantly, budgetary constraints for other strategic initiatives may result from the need to allocate resources to address cybersecurity threats.

Other possible material effects include, but are not limited to intellectual property theft, increased insurance premiums, unplanned litigation costs, reputation damage, and regulatory non-compliance.

Overview

Since its inception in 2018, AON has offered an innovative model of physician-led, community-based oncology management. AON preserves and elevates community oncology by helping its physicians navigate the complex healthcare landscape, providing them an efficient platform to work autonomously and thrive, and most importantly, improving the quality of patient care that is being delivered. We are an alliance of physicians and veteran healthcare leaders partnering to ensure the long-term success and viability of oncology diagnosis and treatment in community-based settings. As of December 31, 2023, we have approximately 206 physicians and advanced practice providers across 86 locations in 19 states and the District of Columbia. Our robust platform provides oncology practices with comprehensive support, access to revenue- diversifying adjacent services and practice management expertise to empower physicians to make cancer care better for every patient.

Our mission is to provide high quality, cost effective cancer care close to where patients live and work. We believe the key to accessible and equitable healthcare lies in the strength of community healthcare practices and we are committed to closing the gap in cancer care to ensure every patient has access to the optimal, comprehensive care needed to help in their fight against cancer. To accomplish this, we have practices in some of the most densely populated cities as well as rural areas where medical resources are scarce. We deliver cancer care innovation by bringing new treatments to the forum and also by ensuring access to the necessary adjacent services to provide comprehensive quality cancer care and preserving the delivery of personalized cancer care in the community oncology setting.

Through access to care-enhancing patient services such as a centralized specialty pharmacy, wide ranging clinical lab and pathology services, clinical research, diagnostic imaging, a fully integrated technology platform anchored by an oncology- specific electronic medical record system, as well as a caring management team and a variety of financial assistance programs, our patients receive expert cancer care at each of our clinics.

We provide patients a variety of services to enhance patient care throughout the healthcare journey: high-quality and timely laboratory services for routine and specialized testing; in-house professional and technical pathology services providing complete, accurate and timely pathology reports; in-house specialty pharmacy with patient education, financial assistance, and 24/7 patient assistance; and care management support services including nutrition guidance.

As the future of healthcare continues to transition from volume to value, we are at the forefront of this initiative by ensuring we remain focused on care quality over care quantity and maintaining a patient-first mentality. Through an integrated system of seamless communication, coordination and patient care for better health outcomes, AON practices benefit from decreased expenditures through the implementation of centralized administrative services, processes, and technologies designed to support effective decision- making such as optimal pricing on drugs and medical supplies. Our patients benefit through our 24/7 clinical care support leading to a reduction in unnecessary emergency room visits and admissions and enhanced care quality. Ultimately, the payors benefit from more efficient delivery of high-quality, comprehensive services comparable to any hospital system at a lower cost point.

Though our network spans the country, our clinicians are interconnected and focused on driving change not just at their local clinics, but throughout our network. Our Network Practices not only unite in collaboration through a physician advisory board, but they also remain at the forefront of new discoveries and findings by expanding and improving cancer

treatment options for every patient through a Pharmacy and Therapeutics Committee that continuously updates its formulary in real time as advanced therapeutics come to market and through participating in clinical research to ensure we remain on the cutting edge of cancer protocols. Patients benefit from convenient access to clinical trials that we participate in without the need to travel to large cities or tertiary cancer care facilities, and personalized care by matching a patient’s cancer to a tailored therapy using molecular profiling.

We have invested significantly in a resilient, integrated technology platform to support the practices which includes a fully integrated electronic health record and a robust decision support tool and analytics engine. Our development of compliance materials ensures consistency and optimal patient experiences that meets or exceeds the Office of Inspector General (“OIG”) guidelines.

The Business Combination

(“AON Class C Preferred Investor”), and DTOC Merger Sub, Inc., a direct, wholly owned subsidiary of DTOC (“Merger Sub”) entered into a Business Combination Agreement (the “Business Combination Agreement”), dated as of June 14, 2023 (which further amended and restated the Business Combination Agreement entered into by DTOC and AON as of October 5, 2022, and amended and restated on January 6, 2023, and April 27, 2023), pursuant to which, among other transactions, on September 20, 2023 (the “Closing Date”), DTOC and AON undertook a series of transactions (the “Business Combination”) resulting in the organization of the combined post-business combination company as an umbrella partnership C corporation, in which substantially all of the assets and the business of the combined company are held by AON LLC, and DTOC became a member of AON LLC. In connection with the closing of the Business Combination (“the Closing”), DTOC changed its name to “American Oncology Network, Inc.”. The Business Combination was completed on September 20, 2023.

As a result of, and in connection with, the Closing, among other things, (i) AON LLC amended and restated its operating agreement (the “Amended and Restated AON LLC Agreement”) to reclassify its existing Class A units, Class A-1 units and Class B units into a single class of AON LLC common units (“AON LLC Common Units”) that can be exchanged on a one-to-one basis for shares of New AON Class A common stock (“New AON Class A Common Stock”) and its existing AON LLC Class C units into AON LLC Series A preferred units (AON LLC Series A Preferred Units”); (ii) AON LLC converted profit pool units of certain of AON LLC’s subsidiaries into an equal number of AON LLC Common Units and shares of New AON Class B common stock (“New AON Class B Common Stock”), which together are exchangeable into shares of New AON Class A Common Stock (together with the New AON Class B Common Stock, the “New AON Common Stock”); (iii) New AON amended and restated its charter (the “Charter”) to provide for (a) the conversion of all existing shares of DTOC Class B common stock into shares of New AON Class A Common Stock on a one-to-one basis, (b) amendment of the terms of New AON Class B Common Stock to provide holders voting rights but no economic rights and (c) designation of a new series of New AON preferred stock as Series A convertible preferred stock (the “New AON Series A Preferred Stock” or “Series A Preferred Stock") with such rights and preferences as provided for in the certificate of designation of the New Aon Series A Preferred Stock (the “New AON Series A Certificate of Designation”); and (iv) among other things, (a) AON LLC issued common units to New AON in exchange for a combination of cash and shares of New AON Class B Common Stock and warrants to acquire shares of New AON Class B Common Stock (the “Class B Prefunded Warrants”), (b) New AON was admitted as a member of AON LLC, (c) AON LLC distributed shares of New AON Class B common stock or Class B Prefunded Warrants, as applicable, to AON LLC equity holders, (d) New AON reserved a specified number of additional shares of New AON Class A Common Stock after the Closing for issuance to eligible participants, (e) Merger Sub merged with and into the AON Class C Preferred Investor whereby the separate existence of Merger Sub ceased and New AON issued a number of shares of New AON Series A Preferred Stock equal to the number of AON LLC Series A preferred units held by the AON Class C Preferred Investor to AEA Growth Management LP, the parent of AON Class C Preferred Investor (“AEA Growth”) in exchange for all the shares of common stock held by AEA Growth in the AON Class C Preferred Investor (the “First Step”), (f) promptly after the First Step, the AON Class C Preferred Investor merged with and into New AON whereby the separate existence of the AON Class C Preferred Investor ceased and New AON held all the AON LLC Series A preferred units and (g) from and after the Closing (but subject to lock-up restrictions), the AON LLC common equity holders (other than New AON), referred to herein as “Legacy AON Stockholders” (former AON LLC Class A, Class A-1, and Class B unit holders), will

Key Factors Affecting Performance & Non-GAAP Measures

Factors Affecting Our Revenues

There are many factors that drive patient service revenues; however, we focus on certain key metrics such as:

•Total patient encounters which include initial consultations and treatments, new patient encounters, recurring patient encounters and treatments, and cancer vs non cancer patients.

•Patient referrals which are also an important driver of patient service revenue; we manage the referral pipeline locally through the coordinated efforts of our physician liaisons working with our physicians to market our practices by visiting referral sources such as, primary care providers and other medical specialties.

Table of Contents

Factors Affecting Our Operating Costs

Operating costs are primarily dependent upon factors such as:

•The cost of prescription drugs used in our treatment plans which include both intravenous and oral oncolytics. The management of these costs are a critical component of our business as it is our single largest expense. We manage this cost by strategic volume purchases and continuously evaluating the most clinically effective drug for cancer type through our Pharmaceutical and Therapeutics Committee.

•Clinical compensation and benefits, including non-medical personnel, represent our second largest operating expense. These costs are impacted by both micro and macro-economic factors as well as local competition for personnel that could impact costs associated with personnel. In particular, in all of our markets, we have seen significant increases in compensation for qualified nursing resources. We continuously monitor wages period over period to mitigate the impact of variations in industry and macro-economic labor conditions.

•We lease all of our facilities, therefore real-estate costs are a significant component of our operating costs. We continuously monitor local and national real estate conditions to actively manage our exposure to fluctuating occupancy costs.

Key Non-GAAP Financial Measures We Use to Evaluate Our Performance

Adjusted EBITDA

This filing includes the non-GAAP financial measure “Adjusted EBITDA”. Management views this metric as a useful way to look at the performance of our operations between periods and to exclude decisions on capital investment and financing that might otherwise impact the review of profitability of the business based on present market conditions. Management believes this measure provides an additional way of viewing aspects of the Company’s operations that, when viewed with the GAAP results, provides a more complete understanding of the Company’s results of operations and the factors and trends affecting the business.

Adjusted EBITDA is defined as net income prior to interest income, interest expense, income taxes, and depreciation and amortization, as adjusted to add back certain other non-cash charges that we may record each year, such as stock-compensation expense, as well as non-recurring charges such as expenses incurred related to major operational transitions and transaction costs. We believe these expenses and non-recurring charges are not considered an indicator of ongoing company performance. The measures are used as a supplement to GAAP results in evaluating certain aspects of our business, as described below. We believe Adjusted EBITDA is useful to investors in evaluating our performance because the measure considers the performance of our operations, excluding decisions made with respect to capital investment, financing, and other non-recurring charges as outlined above.

The Company includes Adjusted EBITDA because it is an important measure upon which our management uses to assess the results of operations, to evaluate factors and trends affecting the business, and to plan and budget future periods. However, non-GAAP financial measures should be considered a supplement to, and not as a substitute for, or superior to, the corresponding measures calculated in accordance with GAAP. Non-GAAP financial measures used by management may differ from the non-GAAP measures used by other companies, including the Company’s competitors. Management encourages investors and others to review the Company’s financial information in its entirety, and not to rely on any single financial measure. Adjusted EBITDA should not be considered as an alternative to net income as an indicator of our performance or as an alternative to any other measure prescribed by GAAP as there are limitations to using such non-GAAP measures. We compensate for these limitations by providing disclosure of the differences between Adjusted EBITDA and GAAP results, including providing a reconciliation to GAAP results, to enable investors to perform their own analysis of our operating results.

Components of Results of Operations

Patient Service Revenue, net

The Company receives payments from the following sources for services rendered: (i) commercial insurers; (ii) pharmacy benefit managers (“PBMs”); (iii) the federal government under the Medicare program administered by the Centers for Medicare and Medicaid Services (“CMS”); (iv) state governments under Medicaid and other programs, including managed Medicare and Medicaid; and (v) individual patients.

Table of Contents

The primary elements of patient service revenue are from fee for service (“FFS”) revenue which includes revenue from required patient infusion and injection treatments, as well as oral prescription drugs. FFS revenue comprise revenues in which we bill and collect for medical services rendered by our physicians or nurse practitioners including office visits and consults. FFS revenue also includes infusion therapies and treatment. FFS revenue consists of fees for medical services provided to patients. Payments for services provided are generally less than billed charges. The Company records revenue net of an allowance for contractual adjustments, which represents the net revenue expected to be collected from third-party payors (including managed care, commercial, and governmental payors such as Medicare and Medicaid), and patients.

These expected collections are based on fees and negotiated payment rates in the case of third-party payors, the specific benefits provided for under each patient’s healthcare plan, mandated payment rates in the case of Medicare and Medicaid programs, and historical cash collections (net of recoveries). The recognition of net revenue (gross charges less contractual allowances) from such services is dependent on certain factors, such as, the proper completion of medical charts following a patient encounter, proper medical coding of the charts, and the verification and authorization of each patient’s eligibility at the time services are rendered as to the payor(s) responsible for payment of such services.

Oral prescription drugs comprise revenues from prescriptions written by our doctors to their patients which are dispensed directly by AON’s specialty pharmacy. Revenue for the oral prescription is based on fee schedules set by various PBMs and other third-party payors. The fee schedule is often subject to direct and indirect remuneration (“DIR”) fees, which are based primarily on adherence and other metrics. DIR fees may be significant and may be assessed in the periods after payments are received against future payments. The Company recognizes revenue, net of estimated DIR fees, at the time the patient takes possession of the oral drug.

Other Revenue

Other revenue is primarily generated from service arrangements with various hospitals systems and data contracts as well as through clinical trials.

Cost of Revenue

Cost of services primarily includes chemotherapy drug costs, clinician salaries and benefits, medical supplies, and clinical occupancy costs. Clinicians include oncologists, advanced practice providers such as physician assistants and nurse practitioners, and registered nurses. Specialty pharmacy costs primarily include the cost of oral medications dispensed from the specialty pharmacy including overhead costs for running a free-standing pharmacy and shipping costs to patients.

General and administrative

Our general and administrative expenses include corporate occupancy costs, technology infrastructure, operations, clinical and quality support, finance, legal, human resources, and business development. Depreciation and amortization expenses are also included in general and administrative expenses. The Company expects its general and administrative expenses to increase over time following the consummation of the Business Combination due to the additional legal, accounting, insurance, investor relations and other costs that the Company will incur as a public company, as well as other costs associated with continuing to grow the business. While we expect general and administrative expenses to increase in the foreseeable future, such expenses on average are expected to decrease as a percentage of revenue over the long term, as the company continues to scale its operations.

Transaction Expenses

Transaction expenses consist of legal services, professional fees and other due diligence expenses that were incurred in connection with the Business Combination. These transaction expenses are considered non-recurring and as a result are included as an add-back in the Company’s adjusted EBITDA calculation.

Comparison of the Years Ended December 31, 2023 and 2022

Revenue


	Year Ended December 31,				Change
(dollars in thousands)	2023		2022		$		%
Patient service revenue, net	$	1,265,719	$	1,137,932	$	127,787	11.2	%
Other revenue	13,466		11,738		1,728		14.7	%
Total revenue	$	1,279,185	$	1,149,670	$	129,515	11.3	%

Revenue increased by $129.5 million, or 11.3%, primarily due to a $127.7 million increase in patient service revenue and a $1.7 million increase in other revenue.

Patient service revenue, net

The $127.7 million increase in revenue is largely attributable to an increase of patient encounters of 7.9% driving $89.9 million of the revenue increase. $58.5 million of increase in patient service revenue was due to an increased revenue per encounter of 4.8% seen within the period. This revenue growth was constrained in part by approximately $20.7 million of incremental implicit price concessions associated with accounts receivable in our legacy billing system as the Company transitioned its billing and collection efforts to a new billing system in the fourth quarter of 2023.

Other revenue

Other revenue increased $1.7 million primarily due to an increase in service arrangements and data contracts.

* — % not meaningful

Operating expenses increased $184.2 million, or 16.1%, due to a $142.1 million increase in cost of revenue, a $14.1 million increase in general and administrative expenses and a $27.9 million increase in transaction expenses.

Cost of revenue

Cost of revenue increased $142.1 million which was primarily driven by drug and medical supply costs, due to both increased patient encounters and cost per encounter. The volume of patient encounters at our practices increased cost of revenue by $70.4 million, and the cost per encounter drove a $66.2 million increase. The increased cost of patient encounters was driven by a combination of higher drug and supply costs as well as the drug and service mix patients required. The Company incurred a one time, non-recurring $4.8 million of non-cash stock compensation expense as a result of closing of the transaction.

General and administrative expense

The $14.1 million increase in general and administrative expenses was primarily driven by a $7.1 million increase in revenue cycle costs associated with the Company’s growth and optimization of our revenue cycle function offset by $1.1 million reduction in corporate compensation. The Company also saw an increase of $2.1 million in insurance and accounting fees as a result of being publicly traded, $1.8 million in depreciation and amortization costs, $1.5 million increase in computer expense as a result of Company's AthenaIDX RCM conversion, as well as another $2.9 million in operating type costs related to office expenses, repairs & maintenance, utilities, contract labor, bank fees and travel expenses relative to Company growth.

Transaction expense

The $27.9 million increase in transaction expenses was driven by the legal, accounting, and consulting fees incurred by the Company due to the Business Combination that closed in September of 2023.

Other (expense) income, net

The increase in other expense is attributable to a non-cash charge of $8.3 million related to the fair value adjustment of the Class A-1 & Class C derivative liability, in addition to a non-cash charge of $1.0 million related to the change in fair value of the Public and Private Warrant liabilities.

Revenue increased by $205.9 million, or 21.8%, primarily due to a $200.0 million increase in patient service revenue and a $6.2 million increase in other revenue.

Patient service revenue, net

The $199.7 million increase in patient service revenue is largely attributable to an increase of patient encounters of 14.9% driving $139.5 million of the revenue increase. The remaining $60.1 million increase in patient service revenue was due to an increased revenue per encounter of 5.6% seen within the period.

Other revenue

Other revenue increased $6.2 million primarily due to a clinical trial agreement entered into during 2022 and an increase in professional services agreements whereby the Company’s physicians provide services to various hospital systems.

Operating expenses increased $201.3 million, or 21.3%, due to a $188.4 million increase in cost of revenue, a $9.6 million increase in general and administrative expenses and a $3.3 million increase in transaction expenses.

Cost of revenue

Cost of revenue increased $188.4 million which was primarily driven by an increase of $167.3 million of drug and medical supply costs, $3.4 million of occupancy costs, and $17.3 million in clinical compensation.

The volume of patient encounters at our practices increased cost of revenue by $107.6 million, and the cost per encounter drove a $59.7 million increase. The cost of patient encounter was driven by a combination of higher drug and supply costs as well as the drug and service mix patients required.

General and administrative expense

The increase in general and administrative expenses were primarily driven by a $7.0 million increase in corporate compensation due to the termination of the Company’s third party back office provider in 2021 which resulted in ramping up hiring of corporate personnel as well as increases due to the inflationary effects of tight labor markets nationally.

Further, there was a $4.7 million increase in IT costs, $4.7 million increase in consulting & accounting fees, and a $1.5 million increase in postage costs. These increases were offset by a decrease of approximately $4.7 million in central service fees as well as a $1.5 million decrease in value-based care costs related to the federal oncology care model which ended in December of 2021.

Transaction expense

The $3.3 million increase in transaction expenses was driven by the legal, accounting, and consulting fees incurred by the Company due to the Business Combination that closed in September of 2023.

Liquidity and Capital Resources

General

To date, the Company has financed its operations principally through the issuance of membership units and long-term debt, and to a lesser extent, cash flows from operations. As discussed below, on June 7, 2023, the Company entered into an agreement to issue Class C Preferred Units for net proceeds of approximately $64.5 million. As of December 31, 2023, the Company had $28.5 million of cash and cash equivalents, $35.4 million of short-term marketable securities, $81.3 million in outstanding long-term indebtedness, and $1.0 million of availability under its PNC Line of Credit.

The Company may incur operating losses and generate negative cash flows from operations for the foreseeable future due to the investments management intends to continue making in expanding operations and sales and marketing and due to additional general and administrative expenses management expects to incur in connection with operating as a public company. As a result, the Company may require additional capital resources to execute strategic initiatives to grow the business.

Management believes that the cash on hand, operating cash flows, and availability under PNC Facility will be sufficient to fund the Company’s operating and capital needs for at least the next 12 months. The Company’s actual results may vary due to, and its future capital requirements will depend on, many factors, including its organic growth rate and the timing and extent of acquisitions of new clinics and expansion into new markets. The Company may in the future enter into arrangements to acquire or invest in complementary businesses. The Company could use its available capital resources sooner than management currently expects. The Company may be required to seek additional equity or debt financing.

Reverse Recapitalization

Table of Contents

The Company closed the Business Combination on September 20, 2023 (“the Closing” or the “Closing Date”). As of the Closing, the Company received $1.4 million of the remaining cash held in the Trust Account after all redemptions. On the Closing Date, the Company paid $7.1 million of DTOC transaction expenses incurred as a result of the Business Combination. The Company assumed an additional $6.1 million in liabilities, of which $3.4 million were related to an excise tax and $2.7 million related to unpaid transaction expenses incurred by DTOC as a result of the Business Combination.

Significant Financing Transactions

2022 Debt Financing Activity

In 2022, the Company amended the PNC Facility and Line of Credit agreements. The primary changes included an increase of the Facility limit from $75.0 million to $125.0 million, a decrease of the PNC Line of Credit amount from $5.0 million to $1.0 million, interest charges to be calculated based on the Bloomberg Short-Term Bank Yield Index plus 1.65% and certain financial covenants. As part of the amendments, the Company drew an additional $16.3 million in proceeds under the Facility.

The total amount outstanding under the PNC Facility as of December 31, 2023 was $81.3 million at an interest rate of 7.19%. No amounts were drawn down on the PNC Line of Credit as of December 31, 2023.

2023 Sale of Class C Equity

On April 27, 2023, AON LLC and the AON Class C Preferred Investor entered into a Unit Purchase Agreement, which they subsequently amended and restated on June 7, 2023 (as amended, the “Unit Purchase Agreement”), which provides for an investment of at least $65.0 million with an option to increase the investment to $75.0 million in connection with the issuance of AON Class C Convertible Preferred Units (“AON Class C Units”) to the AON Class C Preferred Investor.

Pursuant to the Unit Purchase Agreement, on June 7, 2023, the AON Class C Preferred Investor purchased, and AON LLC issued and sold to the AON Class C Preferred Investor, 2,459 AON Class C Units at an aggregate purchase price of $65.0 million. Under the Unit Purchase Agreement, the AON Class C Preferred Investor has an option to purchase an additional 378 AON LLC Class C Units until the closing of the Business Combination (the “Closing”), at a purchase price of $26,432 per Unit. This option was not exercised and expired as of the Closing of the Business Combination. In connection with the Class C Unit sale, AON LLC amended and restated its operating agreement, to among other things, authorize 2,837 AON LLC Class C Units of which 2,459 were outstanding as of June 30, 2023 to the AON Class C Preferred Investor. The AON LLC Class C Units were reclassified into AON LLC Series A Preferred Units as of September 20, 2023, the Closing Date. Concurrently, New AON issued a number of shares of New AON Series A Preferred Stock equal to the number of AON Series A Preferred Units held by the AON Class C Preferred Investor to AEA Growth Management LP, the parent of AON Class C Preferred Investor (“AEA Growth”) in exchange for all the shares of common stock held by AEA Growth in the AON Class C Preferred Investor. Promptly after the First Step, the AON Class C Preferred Investor merged with and into New AON whereby the separate existence of the AON Class C Preferred Investor ceased and New AON held all the AON Series A Preferred Units.

2023 Debt Financing Activity

On June 30, 2023, AON entered into Amendment No. 7 to its PNC Loan Facility which primarily extended the maturity date of the Facility from April 30, 2024 to June 30, 2026.

On December 31, 2023, AON entered into Amendment No. 3 to its Line of Credit agreement to modify certain definitions such as “change in control”. In addition, this also amended certain debt covenants, such as the EBITDA thresholds.

Cash Flows

Historical information regarding sources of cash and capital expenditures in recent periods and analysis of those sources and uses is provided below.

Net cash provided by financing activities	55,265		15,347		39,918		260.1	%

Cash flows from operating activities

Net cash used in operating activities was $18.1 million during the year ended December 31, 2023 compared to $6.8 million used in operations for the comparable period for 2022. The $11.3 million period over period decrease was primarily attributable to:

•The decrease in cash generated from operating activities as a result of the cash flow impacts of net loss, after giving effect to non-cash reconciling items, of $29.8 million for the year ended December 31, 2023 when compared to December 31, 2022. The decrease was primarily attributable to the $44.7 million change in net income, a $10.2 million loss on change in fair value of derivatives and $4.9 million of non-cash stock compensation.

•The operating cash flows period over period were negatively impacted by a $14.6 million net increase to working capital components.

•The impacts from changes in the Medicare advance payments liability, which had no impact on cash flows in the year ended December 31, 2023, but had a $3.7 million negative impact in the year ended December 31, 2022.

Cash flows from investing activities

Net cash used in investing activities was $35.6 million for the year ended December 31, 2023 compared to $14.0 million for the comparable period for 2022. The increase in cash used period over period was primarily attributable to the following:

•Purchases of marketable securities for the year ended December 31, 2023 of $67.4 million were offset by sales of marketable securities of $42.3 million. Purchases of marketable securities for the year ended December 31, 2022 were $12.6 million offset by sales of $2.7 million during this period. This difference resulted in a $15.1 million increase in cash used between periods.

•Purchases of property and equipment was $12.3 million during the year ended December 31, 2023 compared to $7.2 million for the comparable period.

•A decrease in the proceeds related to the disposal of property and equipment period over period.

Cash flows from financing activities

Net cash provided by financing activities was $55.3 million for the year ended December 31, 2023 compared to $15.4 million for the comparable period for 2022. The period over period increase in cash flows from financing activities was primarily attributable to:

•Issuance of Class C Units which resulted in net proceeds of $65.0 million and proceeds received from the Reverse Recapitalization of $1.5 million. This was offset by distributions to Class A and A-1 members of $9.5 million paid in connection with the Business Combination.

•Reduction in borrowings on long-term debt, which were $0 million during the year ended December 31, 2023 compared to $16.3 million in prior period.

•There was no debt repayment in either year ended December 31, 2023 or December 31, 2022.

•Class A and A-1 preferred returns and related tax distributions of $9.5 million during the year ended December 31, 2023, compared to $0 million in the prior period.

Net cash provided by financing activities	15,347		26,544		(11,197)		42.2	%

Cash flows from operating activities

Net cash used in operating activities was $6.8 million during the year ended December 31, 2022 compared to $26.3 million for the comparable period for 2021. The $19.6 million period over period improvement was primarily attributable to:

•The impacts from the reduction in the Medicare advance payments liability, which was reduced from $3.7 million as of December 31, 2021 to $0.0 as of December 31, 2022, resulting in a $3.7 million use of cash for the year ended December 31, 2022. This compared to the reduction in the same liability of $13.5 million from December 31, 2020 to December 31, 2021, which resulted in a $13.5 million use of cash in the year ended December 31, 2021. The difference in this liability reduction is a net increase in operating cash flows of approximately $9.8 million when comparing the periods.

•The improvements in period over period cash flows from operations also include an increase in cash generated from operating activities as a result of the cash flow impacts of net income, after giving effect to non-cash reconciling items, of $11.8 million for the year ended December 31, 2022 when compared to December 31, 2021. This improvement was primarily attributable to a $10.4 million non-cash adjustment due to the amortization of right-of-use assets added as part of the adoption of Accounting Standards Codification 842 – Leases as well as a $2.7 million increase in net income.

•The above is partially offset by approximately $1.9 million increase in use of cash related to the net impact of working capital changes between the periods.

Cash flows from investing activities

Net cash used in investing activities was $14.0 million for the year ended December 31, 2022 compared to $10.7 million for the comparable period for 2021. The increase in cash used period over period was primarily attributable to purchases of marketable securities of $12.6 million for the year ended December 31, 2022, offset by proceeds from sales of marketable securities of $2.7 million. There were no purchases or sales of marketable securities during the comparable period. The increase in cash used above was partially offset by the following:

•Purchases of property and equipment was $7.2 million for the year ended December 31, 2022, lower than $8.3 million for the comparable period.

•Acquisition of physician practices decreased approximately $3.2 million period over period.

•An increase of $1.4 million in proceeds related to the disposal of property and equipment period over period.

Cash flows from financing activities

Net cash provided by financing activities was $15.3 million for the year ended December 31, 2022 compared to $26.5 million for the comparable period for 2021. The period over period decrease in cash flows from financing activities was primarily attributable to:

Table of Contents

•Borrowing on long-term debt was $16.3 million for the year ended December 31, 2022 compared to $65.0 million in the comparative period. The amounts in 2021 were related to the PNC Loan Facility, and the amounts in 2022 are related to $16.3 million which was borrowed when the Company entered into an amendment to the PNC Loan Facility which increased the Facility limit to $125 million.

•The period over period reduction in cash provided was offset by the repayment of $37.1 million of long-term debt (from the prior Truist Loan and Revolver, which was extinguished in 2021 with the issuance of our PNC Loan Facility) during the year ended December 31, 2021. There was no debt repayment in the year ended December 31, 2022.

Off Balance Sheet Arrangements

As of the date of this Annual Report on Form 10-K, AON does not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors. The term “off-balance sheet arrangement” generally means any transaction, agreement or other contractual arrangement to which an entity unconsolidated with AON is a party, under which it has any obligation arising under a guarantee contract, derivative instrument or variable interest or a retained or contingent interest in assets transferred to such entity or similar arrangement that serves as credit, liquidity or market risk support for such assets.

AON does not engage in off-balance sheet financing arrangements.

Material Cash Requirements

Based on the Company’s borrowings under the long-term debt arrangement as of December 31, 2023, the Company expects future cash outflows related to interest expense (based on Bloomberg Short-Term Bank Yield Index rate of 7.19% as of December 31, 2023) of $5.8 million in 2024.

The Company also expects a cash outflow of $81.3 million related to the repayment of principal when the PNC Loan Facility matures in June of 2026.

The Company expects the following cash flows related to operating leases with third parties: $6.9 million in 2024, $7.3 million in 2025, $6.8 million in 2026, $5.7 million in 2027, $4.3 million in 2028, and $16.8 million thereafter.

The Company expects the following cash flows related to operating leases with related parties: $2.5 million in 2024, $2.4 million in 2025, $2.4 million in 2026, $2.3 million in 2027, $1.7 million in 2028, and $1.3 million thereafter.

Cash outflows related to certain vendor contracts with committed expenditures are expected to total approximately $1.6 million in 2024.

The Company does not have any significant supply or other arrangements which result in material cash requirements other than as described above.

Critical Accounting Policies and Estimates

The accompanying consolidated financial statements have been prepared in accordance with GAAP. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.

Revenue Recognition

Revenue is recognized under Accounting Standards Update (“ASU”) 2014-09 Revenue from Contracts with Customers (“Topic 606”). The Company determines the transaction price based upon standard charges for goods and services with anticipated consideration due from patients, third-party payors (including health insurers and government agencies) and others. The Company’s revenue is primarily derived from patient service revenues, which encompass oncology services provided during patient encounters and shipments of pharmacy prescriptions. Performance obligations for the Company’s services provided to patients and most procedures, are satisfied over the time of visit which is the same day services are performed. Performance obligations relating to pharmacy revenue are considered fully satisfied at a point

Table of Contents

in time upon the customer receiving delivery of the prescription. Accordingly, the Company does not anticipate a significant amount of revenue from performance obligations satisfied (or partially satisfied) in previous periods.

As services are performed and prescriptions are shipped, timely billing occurs for services rendered and prescriptions shipped less discounts provided to uninsured patients and contractual adjustments to third-party payors based upon prospectively determined rates and discounted charges. Payment is requested at the time of service for self-paying patients and for patients covered by third-party payors that are responsible for paying deductibles and coinsurance.

The Company monitors revenue and receivables to prepare estimated contractual allowances for the anticipated differences between billed and reimbursed amounts. Payments from third-party payors and Government programs including Medicare and Medicaid may be subject to audit and other retrospective adjustments. Such amounts are considered on an estimated basis when net patient revenue is recorded and are adjusted as final adjustments are determined.

The Company has a system and estimation process for recording Medicare net patient service revenue and estimated recoupments as it relates to value-based care (“VBC”) revenue included in patient service revenue on the Consolidated Statements of Operations and Comprehensive Income (Loss). The Company’s VBC revenue is primarily generated through its participation in the Enhancing Oncology Model (“EOM”) which is an episode-based payment model to promote high-quality cancer care. Participants enter six-month episode periods, and the Company bills a monthly fee during the six-month period based on a fixed rate per participant per month and the total number of participants. Certain quality and compliance metrics are tracked as part of the program and submitted to CMS at the end of the episode period which may result in recoupment of funds. The Company estimates the recoupment amount by developing a recoupment percentage for each period based on historical known recoupment from CMS and applies the recoupment percentage against total fees for the period. Based on the estimate, the Company accrues a liability representing the expected final recoupments based on historical settlement trends.

Accounts Receivable

Accounts receivable from patients are carried at the original charge for the services provided, and an adjustment is made to the receivable in a contra account based on the historical collection rate for the provider and payor combination. This adjustment takes into consideration any allowance for doubtful accounts. Management determines the allowance for uncollectible accounts based on historical experience.

Business Combinations

The Company evaluates acquired practices in accordance with ASU 2017-01, Business Combinations (Topic 805) — Clarifying the Definition of a Business. This standard clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. Because substantially all of the value of each acquired practice did not relate to a similar group of assets and as each acquired practice contained both inputs and processes necessary to provide economic benefits to the Company, it was determined that each acquisition represents a business combination. Therefore, the transactions have been accounted for using the acquisition method of accounting, which requires, with limited exceptions, that assets acquired, and liabilities assumed be recognized at their estimated fair values as of the acquisition date. Any excess of the consideration transferred over the estimated fair values of the net assets acquired is recorded as goodwill. Transaction costs related to business combinations are expensed in the period in which they are incurred.

Professional Liability

The Company maintains an insurance policy for exposure to professional malpractice insurance risk beyond selected retention levels. Reserves are established for estimates of the loss that will ultimately be incurred on claims that have been reported but not paid and claims that have been incurred but not reported. These reserves are established based on consultation with a third-party actuary. The actuarial valuations consider a number of factors, including historical claims payment patterns, changes in case reserves and the assumed rate of increase in healthcare costs. Management believes the use of actuarial methods to account for these reserves provides a consistent and effective way to measure these subjective accruals. However, due to the sensitive nature of this estimation technique, recorded reserves could differ from ultimate costs related to these claims due to changes in claims reporting, claims payment and settlement practices and differences in assumed future cost increases. Accrued unpaid claims and expenses that are expected to be paid within the next twelve months are classified as current liabilities and included in accrued other. All other accrued unpaid claims and expenses are classified as long-term liabilities and included in other long-term liabilities. Insurance recoveries associated with the unpaid claims are classified as long-term assets included in other assets.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of American Oncology Network, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of American Oncology Network, Inc. and its subsidiaries (the “Company”) as of December 31, 2023 and 2022, and the related consolidated statements of operations and comprehensive income (loss), of mezzanine and stockholders' equity and of cash flows for each of the three years in the period ended December 31, 2023, including the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023 in conformity with accounting principles generally accepted in the United States of America.

Change in Accounting Principle

As discussed in Note 2 to the consolidated financial statements, the Company changed the manner in which it accounts for leases in 2022.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Valuation of Patient Services Accounts Receivable – Allowance for Contractual Adjustments

As described in Note 2 to the consolidated financial statements, the Company’s revenue is primarily derived from patient service revenues, which encompass oncology services provided during patient visits and shipments of pharmacy prescriptions. Performance obligations for the Company’s services provided to patients and most procedures are satisfied over the time of visit which is the same day services are performed. Patient service revenue is presented net of the estimated provision for contractual adjustments and uncollectible amounts. As disclosed by management, as services are performed and prescriptions are shipped, timely billing occurs for services rendered and prescriptions shipped less discounts provided to uninsured patients and contractual adjustments to third-party and governmental payors, representing

the amount expected to be collected, based upon prospectively determined rates and discounted charges. Management monitors revenue and receivables to prepare estimated contractual allowances for the anticipated differences between billed and reimbursed amounts. Payments from third-party payors and Government programs including Medicare and Medicaid may be subject to audit and other retrospective adjustments. Such amounts are considered on an estimated basis when net patient revenue is recorded and are adjusted as final adjustments are determined. As of December 31, 2023, the patient accounts receivable, net balance was $129.2 million, of which a majority relates to patient services accounts receivable.

The principal considerations for our determination that performing procedures relating to the valuation of patient services accounts receivable – allowance for contractual adjustments is a critical audit matter are (i) the significant judgment by management when developing the estimated allowance to adjust the patient services accounts receivable to the amount expected to be collected in the future under the terms of third-party and governmental payor contracts and (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating audit evidence related to the valuation of patient services accounts receivable. As disclosed by management, a material weakness existed related to this matter.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included, among others, developing an independent estimate of the amounts expected to be collected and comparing the independent estimate to management’s estimate to evaluate the reasonableness of management’s estimate. Developing an independent estimate involved (i) evaluating the historical accuracy of management’s December 31, 2022 estimate by comparing it to subsequent cash collections; (ii) evaluating the reasonableness of the December 31, 2023 accounts receivable estimate by considering subsequent cash collections; (iii) testing, on a sample basis, the completeness and accuracy of the historical billing and collection data provided by management, used as an input in developing the independent estimate; and (iv) for accounts receivable without cash collected subsequent to December 31, 2023, estimating collections based on the Company’s historical collection patterns.

(a)The Company entered into affiliation agreements with the physicians for these respective practices. The Company evaluated each of the affiliation agreements and determined that the transactions did not represent a business combination.

The operations of the practices that were acquired have been included in the Company’s consolidated financial statements since the date of acquisition.

Business Combination Agreements

Digital Transformation Opportunities Corp. (“DTOC”), American Oncology Network, LLC (“AON LLC”), GEF AON Holdings Corp. (“AON Class C Preferred Investor”), and DTOC Merger Sub, Inc., a direct, wholly owned subsidiary of DTOC (“Merger Sub”) entered into a Business Combination Agreement (the “Business Combination Agreement”), dated as of June 14, 2023 (which further amended and restated the Business Combination Agreement entered into by DTOC and AON LLC as of October 5, 2022, and amended and restated on January 6, 2023, and April 27, 2023), pursuant to which, among other transactions, on September 20, 2023 (the “Closing Date”), DTOC and AON LLC undertook a series of transactions (the “Business Combination”) resulting in the organization of the combined post-business combination company as an umbrella partnership C corporation, in which substantially all of the assets and the business of the combined company are held by AON LLC, and DTOC became a member of AON LLC. In connection with the closing of the Business Combination (“the Closing”), DTOC changed its name to “American Oncology Network, Inc.”. The Business Combination was completed on September 20, 2023.

Accounting Treatment for the Business Combination

As AON LLC does not meet any of the characteristics of a VIE under ASC 810, the Business Combination was evaluated under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805, Business Combinations. Notwithstanding the legal form of the Business Combination pursuant to the Business Combination Agreement, the Business Combination was accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, DTOC was treated as the acquired company and AON LLC was considered the acquirer for financial statement reporting purposes. AON LLC was determined to be the accounting acquirer based on, in summary, an evaluation of the following primary facts and circumstances:

•AON LLC’s directors will represent a majority of the board seats for New AON’s board of directors;

•AON LLC’s senior management will be the senior management of the combined company;

•AON LLC’s operations comprising the ongoing operations of the post-combination company; and

•AON LLC’s relative size (i.e., assets, revenues, and earnings) is significantly larger compared to DTOC.

Accordingly, for accounting purposes, the financial statements of the post-combination entity will represent a continuation of the financial statements of AON LLC with the acquisition being treated as the equivalent of AON LLC issuing stock for the net assets of DTOC, accompanied by a recapitalization. The net assets of DTOC are stated at historical cost, with no goodwill or other intangible assets recorded. Refer to Note 3 for additional information.

Accounting for the Earnout Shares

Following the Closing and for five years thereafter, the DTOC Sponsor agreed to subject 35%, or 2,839,375 shares of New AON Class A common stock held by it as of the Closing (the “Sponsor Earnout Shares”) to the following vesting and forfeiture provisions:

•the Sponsor Earnout Shares will vest when the volume-weighted average price of the New AON Class A common stock equals or exceeds $13.50 per share for any 20 trading days within any 30 trading day period beginning after the Closing and ending 60 months following the Closing;

•the Sponsor Earnout Shares will be released immediately upon the consummation of a change of control transaction within the 60-month period following the Closing; and

•if the Sponsor Earnout Shares are not released pursuant to the foregoing provisions on or before the date that is 60 months after the Closing, then the Sponsor Earnout Shares will be forfeited immediately following such date.

As the Business Combination was accounted for as a reverse recapitalization, the issuance of the Sponsor Earnout Shares to the Company’s existing stockholders will be accounted for as an equity transaction. The accounting for the Sponsor Earnout Shares was evaluated under ASC Topic 480, Distinguishing Liabilities from Equity, and ASC Subtopic 815-40, Derivatives and Hedging — Contracts in Entity’s Own Equity, to determine if the Sponsor Earnout Shares should be classified as a liability or within equity. As part of that analysis, it was determined that the Sponsor Earnout Shares are freestanding, do not meet the criteria within ASC 480 to be classified as a liability, and meet the criteria in ASC 815-40 to be considered indexed to the post-combination entity’s common stock and classified within equity.

Warrants

As of the Closing Date, New AON assumed the outstanding warrants (Public Warrants and Private Placement Warrants) that were issued by DTOC as part of DTOC’s IPO. Further, New AON issued the Class B Prefunded

Table of Contents

Warrants to former Class A-1 unit holders, in lieu of New AON Class B Common Stock. The accounting treatment for the Public Warrants, the Private Placement Warrants, and the Class B Prefunded Warrants, collectively referred to as “the Warrants”, is disclosed in Note 2.

Public Warrants

As of the Closing Date, New AON assumed 8,337,500 public warrants (the “Public Warrants”) issued by DTOC in its IPO. Each whole warrant entitles the holder to purchase one share of New AON Class A Common Stock at a price of $11.50 per share, subject to adjustment. The warrants will become exercisable on the later of 12 months from the closing of the DTOC Initial Public Offering or 30 days after the completion of its initial business combination and will expire five years after the Closing of the Business Combination, or earlier upon redemption or liquidation.

Private Warrants

As of the Closing Date, New AON assumed 6,113,333 Private Placement Warrants held by the DTOC Sponsor (the “Private Placement Warrants” or “Private Warrants”). The Private Placement Warrants will be non-redeemable in certain circumstances so long as they are held by the Sponsor or its permitted transferees. The Private Placement Warrants may also be exercised by the Sponsor and its permitted transferees for cash or on a cashless basis. Otherwise, the Private Placement Warrants have terms and provisions that are identical to those of the Public Warrants, including as to exercise price, exercisability, and exercise period.

Class B Prefunded Warrants

As of the Closing Date, New AON issued 3,000,245 of Class B Prefunded Warrants to former AON Class A-1 unitholders. Because the Class B Warrants are prefunded, there was not any cash consideration exchanged as part of the Class B Warrant issuance. Each Class B Prefunded Warrant entitles the holder to purchase one share of New AON Class B common stock at a price of $0.01 per share. The exercise term of the Class B Warrant shall continue indefinitely so long as the holder of the Class B Warrant is also the holder of an AON LLC Common Unit, provided that the number of shares of Common Stock that this Warrant is exercisable for shall not exceed the number of AON LLC Common Units held by holder.

Transaction Expenses

In connection with the Reverse Recapitalization, AON LLC incurred costs of $31.9 million and $3.5 million during the years ended December 31, 2023 and 2022, respectively. Of the total costs incurred during the year ended December 31, 2023, $31.1 million were reported as transaction expenses in the consolidated statements of operations and comprehensive loss and $0.8 million were reported as a reduction of Series A Preferred Stock presented as mezzanine equity on the consolidated balance sheets at December 31, 2023. Additionally, at December 31, 2023 there were $0.9 million of outstanding transaction expenses included within accrued other on the consolidated balance sheets. At December 31, 2022, the Company had accrued $0.3 million of transaction costs related to the Reverse Recapitalization, which were reported as other assets on the consolidated balance sheets. AON LLC recorded $3.2 million of transaction expenses in connection with the Reverse Recapitalization during the year ended December 31, 2022, which were reported as transaction expenses in the consolidated statements of operations and comprehensive loss.

2.Basis of Presentation and Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”).

Table of Contents

For the year ended December 31, 2023, these consolidated financial statements reflect the consolidated results of operations, comprehensive income (loss), cash flows and changes in equity of AON LLC and its wholly-owned subsidiaries for the period of January 1, 2023 through September 20, 2023, the Closing Date of the Reverse Recapitalization, and the consolidated results of operations, comprehensive income (loss), cash flows and changes in stockholders’ equity of AON Inc. and its consolidated subsidiaries, including AON LLC, for the period of September 21, 2023 through December 31, 2023. The consolidated balance sheet at December 31, 2023 presents the financial condition of AON Inc. and its consolidated subsidiaries, including AON LLC, and reflects the initial recording of the assets and liabilities of AON Inc. at their historical cost (see Note 3). All intercompany balances and transactions of AON LLC prior to the Reverse Recapitalization have been eliminated. All intercompany balances and transactions of AON Inc. after the Reverse Recapitalization have been eliminated.

For the years ended December 31, 2022 and 2021, these consolidated financial statements present the consolidated results of operations, comprehensive income (loss), cash flows and changes in equity of AON LLC. The consolidated balance sheet as of December 31, 2022 presents the financial condition of AON LLC and its wholly-owned subsidiaries. All intercompany balances and transactions of AON LLC have been eliminated.

In accordance with ASC 805, Business Combinations, the historical equity of AON LLC has been recasted in all periods up to the Closing Date, to reflect the number of shares of New AON’s Class A Common Stock and Class B Common Stock issued to Legacy AON Stockholders in connection with the Reverse Recapitalization. The Company recasted the units outstanding related to the historical AON LLC Class A, Class A-1, and Class B units prior to the Reverse Recapitalization (“Historical AON LLC Equity”) as common equity of New AON, equal to the Per Company Class Unit Exchange Ratio, pursuant to the Business Combination Agreement.

The Per Company Unit Exchange Ratio at which AON LLC Class A units and Class A-1 units were reclassified is equal to 2,524 AON Common Units. The Per Company Unit Exchange Ratio at which AON LLC Class B units were reclassified varied depending on participation threshold, and is equal to 2,524, 2,453, or 1,976, AON Common Units. The Per Company Unit Exchange Ratio at which Class C units were reclassified is equal to 2,705 AON LLC Series A Preferred Units.

The consolidated financial statements and related notes thereto give effect to the conversion for all periods presented, without any change to par value or per unit amounts. The consolidated financial statements do not necessarily represent the capital structure of New AON had the Reverse Recapitalization occurred in prior periods. The Company has not made retroactive adjustments related to the historical book values of Historical AON LLC Equity as the adjustments were considered immaterial.

Principles of Consolidation

For the period of September 21, 2023 through December 31, 2023, the consolidated financial statements include the accounts of the Company, AON, Inc., AON LLC, and its wholly owned subsidiary American Oncology Management Company, LLC (“AOMC”), and its consolidated variable interest entities (“VIEs”) American

Table of Contents

Oncology Partners, P.A. (“AON Partners”), American Oncology Partners of Maryland, P.A. (“Partners of Maryland”), AON Central Services, LLC (“AON Central Services”), and Meaningful Insights Biotech Analytics, LLC (“MIBA”). All intercompany accounts and transactions between the entities have been eliminated in consolidation.

Refer to Note 1 for the accounting treatment of the Business Combination.

The Company accounts for American Oncology Network, LLC, AON Partners, Partners of Maryland, AON Central Services, and MIBA in accordance with ASC 810, Consolidations. The Company determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a VIE. A VIE is broadly defined as an entity that has any of the following three characteristics: (i) the equity investment at risk is insufficient to finance the entity’s activities without additional subordinated financial support; (ii) substantially all of the entity’s activities either involve or are conducted on behalf of an investor that has disproportionately few voting rights; or (iii) the equity investors as a group lack any of the following, the power through voting or similar rights to direct the activities of the entity that most significantly impact the entity’s economic performance, the obligation to absorb the expected losses of the entity, or the right to receive the expected residual returns of the entity. The Company consolidates a VIE if it has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. Management performs ongoing reassessments of whether changes in the facts and circumstances regarding the Company’s involvement with a VIE will cause the consolidation conclusion to change. Changes in consolidation status are applied prospectively, if any.

AON LLC has contractual relationships with AON Partners, Partners of Maryland and AON Central Services and the physician owners through management service agreements (“MSAs”) and other contractual agreements to provide all practice management services outside of medical services provided by the physicians. In addition, despite not being required by the contractual relationships, AON LLC regularly provides funding to support AON Partners and Partners of Maryland’s operations and acquisitions of physician practices. AON Central Services was formed July 15, 2022 and, effective January 1, 2023, entered into an agreement with AOMC to provide qualified non-clinical and non-medical employees to AOMC to support the operation of the physician practices. MIBA was established during the first quarter of 2023 for the purpose of developing intellectual property to synergize the collection, de-identification, and dissemination of the Company’s patient data for sale to external parties for research, development, and clinical decisions. In May 2023, the Company contributed $0.2 million for a 56% interest in the equity of MIBA. The Company concluded that AON LLC had a controlling financial interest in MIBA and has consolidated the entity at December 31, 2023 and recorded the noncontrolling interest in permanent equity.

The Company has concluded that AON Partners, Partners of Maryland, AON Central Services, and MIBA are all VIEs in which AON LLC has the characteristics of a controlling financial interest and is deemed to be the primary beneficiary. The variable interest subjects AON LLC to all potential losses in the entities and, therefore, requires AON LLC, and in turn AON Inc., to consolidate the results of AON Partners, Partners of Maryland, AON Central Services, and MIBA in its consolidated financial statements.

Refer to Note 4 for further information on the VIEs. Refer to Note 1 for the accounting treatment of the Reverse Recapitalization.

Significant Accounting Policies

Accounting Estimates and Assumptions

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.

Table of Contents

Segments

Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker (the “CODM”). The Company’s CODM is its chief executive officer who reviews financial information together with certain operating metrics principally to make decisions about how to allocate resources and to measure the Company’s performance. The Company has one operating segment and one reportable segment that are structured around the organizational management of oncology practice operations. All revenue and assets are in the United States.

Revenue Recognition

Revenue is recognized under Accounting Standards Update (“ASU”) 2014-09 Revenue from Contracts with Customers (“Topic 606”). Patient service revenue is presented net of the estimated provision for contractual adjustments and uncollectible amounts. The Company determines the transaction price based upon standard charges for goods and services with anticipated consideration due from patients, third-party payors (including health insurers and government agencies) and others. The Company’s revenue is primarily derived from patient service revenues, which encompass oncology services provided during patient visits and shipments of pharmacy prescriptions. Performance obligations for the Company’s services provided to patients and most procedures, are satisfied over the time of visit which is the same day services are performed. Performance obligations relating to pharmacy revenue are considered fully satisfied at a point in time upon the customer receiving delivery of the prescription. Accordingly, the Company does not anticipate a significant amount of revenue from performance obligations satisfied (or partially satisfied) in previous periods, and any such revenue recognized during the years ended December 31, 2023, 2022, and 2021 was immaterial. Additionally, the Company does not expect to recognize material revenue in the future related to performance obligations that are unsatisfied (or partially satisfied) as of December 31, 2023. Approximately $933.9 million, $818.5 million, and $683.0 million of the Company’s revenues are generated from services performed during patient visits with the remainder primarily generated from shipments of pharmacy prescriptions for the years ended December 31, 2023, 2022, and 2021, respectively.

In assessing who is the principal in providing patient services and pharmacy prescriptions, the Company considered who controls the provision of services and prescriptions. The Company has determined they are acting as a principal in these relationships.

In April 2022, the Company entered into a long-term arrangement to sponsor and manage a clinical trial. The Company subsequently contracted with a third-party to provide the clinical research services and is the principal in this arrangement. The performance of clinical research services are considered a single performance obligation because the Company provides a highly-integrated service. Revenue is recognized for the single performance obligation over time due to the Company’s right to payment for work performed to date. The contract provides for invoices based on predetermined milestones.

The Company uses the cost-to-cost measure of progress for the Company’s contract because it best depicts the transfer of control to the customer as the performance obligation is fulfilled. For this method, the Company

Table of Contents

compares the contract costs incurred to date to the estimated total contract costs through completion. As part of the client proposal and contract negotiation process, the Company develops a detailed project budget for the direct costs and reimbursable costs based on the scope of the work, the complexity of the study, the geographical location involved and the Company’s historical experience. The estimated total contract costs at the project level are reviewed and revised periodically throughout the life of the contract, with adjustments to revenue resulting from such revisions being recorded on a cumulative basis in the period in which the revisions are identified. Contract costs consist primarily of direct labor and other reimbursable project-related costs such as travel, third-party vendor costs and investigator fees. The Company establishes pricing based on the Company’s internal pricing guidelines, discount agreements, if any, and negotiations with the client. The transaction price is the contractually defined amount. Revenue related to the clinical trial, which is included within other revenue, was $3.7 million and $4.3 million for the years ended December 31, 2023 and 2022, respectively.

The Company has a system and estimation process for recording Medicare net patient service revenue and estimated recoupments as it relates to value-based care (“VBC”) revenue included in patient service revenue in the consolidated statements of operations and comprehensive loss. The Company’s VBC revenue is primarily generated through its participation in the CMS Oncology Care Model (“OCM”) which is an episode-based payment model to promote high-quality cancer care. Participants enter 6-month episode periods, and the Company bills a monthly fee during the 6-month period based on a fixed rate per participant per month and the total number of participants. Certain quality and compliance metrics are tracked as part of the program and submitted to CMS at the end of the episode period which may result in recoupment of funds. The Company estimates the recoupment amount by developing a recoupment percentage for each period based on historical known recoupment from CMS and applies the recoupment percentage against total fees for the period. Based on the estimate, the Company accrues a liability representing the expected final recoupments based on historical settlement trends.

Short-term Marketable Securities

Investments in marketable securities consist of corporate bonds and U.S. Treasury securities.

Management determines the appropriate classification of investments at the time of purchase and reevaluates such determination at each balance sheet date. Marketable securities are classified as available-for-sale and are carried at fair value in the consolidated balance sheets. The marketable securities are classified as short-term based on management’s intent to convert such securities within one year and the ability to convert them within two to three days.

Certain of our available-for-sale securities are debt securities. For an available-for-sale debt security with an amortized cost that exceeds its fair value, the Company first determines if it intends to sell or will more-likely-than-not be required to sell the security before the expected recovery of its amortized cost. If it intends to sell or will more-likely-than-not be required to sell the security, then the Company recognizes the impairment as a credit loss in the consolidated statements of operations and comprehensive loss by writing down the security’s amortized cost to its fair value. If it does not intend to sell or it is not more-likely-than-not that it will be required to sell the security before the expected recovery of its amortized cost, the Company recognizes the portion of the impairment that is due to a credit loss, if any, in the consolidated statements of operations and comprehensive loss through an allowance. The portion of the impairment that is due to factors other than a credit loss is recognized in other comprehensive income (loss) in the consolidated statements of operations and comprehensive loss as an unrealized loss.

Equity Investment in Affiliate

In January 2023, the Company contributed noncash consideration, with a fair value of approximately $2.3 million, in return for a 49% equity interest in OCP Management Arizona, LLP. Investments in entities over which the Company has the ability to exercise significant influence but does not control the entity are accounted for using the equity method. Equity method investments are included with other assets in the consolidated balance sheets. The carrying amount of the investment is adjusted to reflect the Company’s proportionate share of the net earnings or

Table of Contents

losses and reduced by any dividends received. The Company’s share of income or loss related to this investment is reported as an equity in loss of affiliate in the consolidated statements of operations and comprehensive loss.

Noncontrolling Interests

The Company consolidates the results of entities in which it has a controlling financial interest. Refer to Note 17 for additional considerations and presentation for noncontrolling interest.

Mezzanine Equity

Treasury Stock

We account for treasury stock purchased under the cost method and include treasury stock as a component of accumulated paid in capital. Treasury stock purchased with intent to retire (whether or not the retirement is actually accomplished) is charged to common stock. The Company repurchased 14,729 shares of class A common stock at the spot rate as of each transaction date for a total cost of less than $0.1 million for the year ended December 31, 2023.

Business Combinations

The Company evaluates acquired practices in accordance with ASU 2017-01, Business Combinations (Topic 805)-Clarifying the Definition of a Business. This standard clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. Because substantially all of the value of each acquired practice did not relate to a similar group of assets and as each acquired practice contained both inputs and processes necessary to provide economic benefits to the Company, it was determined that each acquisition represents a business combination. Therefore, the transactions have been accounted for using the acquisition method of accounting, which requires, with limited exceptions, that assets acquired, and liabilities assumed be recognized at their estimated fair values as of the acquisition date. Any excess of the consideration transferred over the estimated fair values of the net assets acquired is recorded as goodwill. Transaction costs related to business combinations are expensed in the period in which they are incurred.

Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Cash and cash equivalents include cash or deposits with financial institutions and deposits in highly liquid money market securities. Deposits with financial institutions are insured by the Federal Deposit Insurance Corporation up to certain defined limits. Bank deposits at times may exceed federally insured limits. The Company has not experienced any losses in these accounts.

Accounts Receivable

Table of Contents

As of December 31, 2023 and 2022, the accounts receivable, net balances were $129.2 million and $136.1 million, respectively.

Inventories

Inventories, consisting primarily of pharmaceuticals finished goods, are valued at the lower of cost or net realizable value, with cost being determined on a first-in, first-out basis. Obsolescence for inventories is estimated based on expiration dates and slow-moving inventory. No obsolescence allowances have been recorded as of December 31, 2023 and 2022. If the Company determines that an item is obsolete, or the expected net realizable value upon sale is lower than the currently recorded cost, a write-down is recorded and charged to cost of revenue to reduce the inventory to its net realizable value and a new cost basis is established. The majority of the Company’s inventories are purchased from a related party (See Note 14).

Other Receivables

Other receivables consist primarily of rebates on drug purchases made in the current period which are offered as an incentive by the distributor and/or manufacturer and are not yet paid as of year-end.

Property and Equipment

Property and equipment are recorded at cost and depreciated using the straight-line method over the estimated useful lives of the assets. A summary of the lives used for computing depreciation is as follows:


Leasehold improvements			1 - 15 years
Furniture, fixtures and equipment			7 years
Medical equipment			5 - 10 years
Computer equipment			5 years
Signs			7 years
Automobiles			5 years
Software			7 years

Leasehold improvements are amortized using the straight-line method over the shorter of their estimated useful lives or the term of the related lease, which may include one or more option renewal periods. Maintenance and repairs that do not improve service potential or extend economic life are expensed as incurred. Expenditures for major improvements and additions are capitalized. Long-lived assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. In assessing long-lived assets for impairment, assets are grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Recoverability is measured by a comparison of the carrying amount of an asset group to the undiscounted future net cash flows expected to be generated by the asset group. If estimated future undiscounted cash flows are not sufficient to recover the carrying value of the assets, impairment is measured by comparing the carrying amount of the assets to the estimated fair value, obtained through appraisal or market quotations, or discounted future net cash flow estimates. The Company did not recognize any long-lived asset impairments during 2023, 2022, and 2021.

Goodwill

Goodwill arising from business combinations represents the excess of the fair value of consideration transferred over the fair value of the identifiable net assets acquired and liabilities assumed as of the acquisition date. Goodwill amounts are not amortized, but rather tested for impairment annually, on October 1, or more often if circumstances

Table of Contents

indicate that the carrying value may not be recoverable. There was no impairment of goodwill during any of the periods presented.

Leases

Effective January 1, 2022, the Company adopted ASU 2016-02, Leases and the subsequently issued supplemental and/or clarifying ASUs known as ASC Topic 842 (collectively “ASC 842”) using the modified retrospective approach. See Recently Adopted Accounting Pronouncements below, which discusses the initial adoption of this new guidance.

The Company’s lease portfolio primarily consists of office and equipment leases for its practice facilities. The Company evaluates whether a contract is or contains a lease at contract inception. A lease exists when a contract conveys to the customer the right to control the use of identified property or equipment for a period of time in exchange for consideration. The definition of a lease embodies two conditions: 1) there is an identified asset in the contract that is land or a depreciable asset (i.e., property, plant, and equipment); and 2) the customer has the right to control the use of the identified asset. ASC 842 requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental borrowing rate. As the Company’s operating leases do not generally provide an implicit rate, the incremental borrowing rate is used based on the information available at commencement date in determining the present value of lease payments. The incremental borrowing rate for a lease is the rate of interest the Company would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms. The lease term for all of the Company’s operating leases include the noncancellable period of the lease plus any additional periods covered by either a lessee option to extend (or not to terminate) the lease that the lessee is reasonably certain to exercise, or an option to extend (or not to terminate) the lease controlled by the lessor. Lease payments included in the measurement of the operating lease right-of-use (“ROU”) assets and lease liabilities are comprised of fixed payments (including in-substance fixed payments), variable payments that depend on an index or rate, and the exercise price of a lessee option to purchase the underlying asset if the lessee is reasonably certain to exercise.

The Company elected not to recognize operating lease ROU assets and lease liabilities for all short-term leases (leases with an initial lease term of 12 months or less). The Company recognizes the lease payments associated with short-term leases as an expense over the lease term.

The operating lease ROU assets are initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. The operating lease ROU assets are subsequently measured throughout the lease term at the carrying amount of the lease liability, plus initial direct costs, plus (minus) any prepaid (accrued) lease payments, less the unamortized balance of lease incentives received. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The operating lease liabilities are initially measured at the present value of the unpaid lease payments at the lease commencement date.

Income Taxes

The Company accounts for its income taxes using the asset and liability method whereby deferred tax assets and liabilities are determined based on temporary differences between the basis used for financial reporting and income tax reporting purposes. Deferred income taxes are provided based on the enacted tax rates in effect at the time such temporary differences are expected to reverse. A valuation allowance is provided for deferred tax assets if it is more likely than not that the Company will not realize those tax assets through future operations.

The Company is a member of American Oncology Network, LLC, which is treated as a partnership for U.S. federal and certain state and local income taxes. As a partnership, American Oncology Network, LLC is not subject to U.S. federal and certain state and local income taxes. Any taxable income or loss generated by American Oncology Network, LLC is passed through to and included in the taxable income of its members, including the Company, in accordance with the partnership agreement. The Company is subject to U.S. federal income taxes, in addition to

Table of Contents

state and local income taxes with respect to the allocable share of any taxable income of American Oncology Network, LLC. Additionally, other corporate entities within the Company’s structure are subject to income taxes.

Accounting for uncertainty in income taxes prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken, or expected to be taken, in a tax return.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and accounts receivable. Although certain cash accounts exceed the federally insured deposit amount, management has not previously experienced nonperformance by any financial institution.

Equity-Based Compensation

The Company measures the compensation cost of all equity awards at the estimated fair value of the award on the date of grant and records the related expense in the accompanying consolidated statements of operations and comprehensive loss on a straight-line basis over the applicable service period. Prior to the closing of the Business Combination, the Company used an option pricing method to value its common stock. This method allocates the fair value of total equity to the various components of equity based on an estimated liquidity event. This option pricing method first values the Company at the enterprise level, and then values breakpoints based on the liquidation preferences of the Class A, Class A-1, and Class B units. An allocation of total equity (enterprise value) is then performed to the various equity components based on the relative rights and privileges of each class of equity. The Company was assisted by third-party valuation experts to apply the above models to calculate the fair value estimate. Forfeitures are accounted for as they occur.

After consummation of the Business Combination, the Company issued an equity incentive plan (“2023 Incentive Equity Plan”). The purpose of the 2023 Incentive Equity Plan is to attract and retain personnel for positions with the Company, to provide additional incentive to employees, directors, and consultants, and to promote the success of the Company’s business. The Plan permits the grant of Incentive Stock Options (“ISO”) to any ISO Employee and the grant of Non statutory Stock Options, Stock Appreciation Rights, Restricted Stock, Restricted Stock Units, and Performance Awards to any Service Provider. As of December 31, 2023, no awards have been granted from the 2023 Incentive Equity Plan.

Debt Issuance Costs

Debt issuance costs consist of legal fees and other professional services and are capitalized. Debt issuance costs are presented in the consolidated balance Sheets as a direct deduction from the carrying value of the associated debt liability and amortized to interest expense in the consolidated statements of operations and comprehensive loss. The costs related to the term loans are amortized using the straight-line method, which approximates the effective interest method, over the terms of the related debt. The amortization related to the debt issuance costs included in interest expense within the accompanying consolidated statements of operations and comprehensive loss was $0.8 million in 2023, $0.6 million in 2022, and $0.4 million in 2021.

Offering Costs

The Company defers specific incremental costs directly attributable to proposed offerings of securities. These costs consist of legal, accounting, and other similar expenses incurred through the balance sheet date that are directly related to a potential offering. If the offering is completed, these costs will be charged against the gross proceeds of the offering. These offering costs will be allocated to the separable financial instruments issued in the transaction on a relative fair value basis of the securities issued, compared to total proceeds received. Offering costs associated with any instruments classified as liabilities will be expensed as incurred, presented as non-operating expenses in the consolidated statements of operations and comprehensive loss.

Table of Contents

During the year ended December 31, 2023, the Company incurred additional deferred offering costs of approximately $0.8 million which were recorded as an offset to the net proceeds of the AON LLC Class C Units (discussed below) in mezzanine equity on the consolidated balance sheets as of December 31, 2023. At December 31, 2022, the Company had incurred approximately $0.3 million of offering costs, which are included in other assets in the accompanying consolidated balance sheets.

As discussed in Note 1, on June 7, 2023, AON LLC issued Redeemable Convertible Preferred Class C Units (“Class C Units” or “AON LLC Class C Units”) for net proceeds of approximately $64.5 million ($65.0 million in gross proceeds, net of $0.5 million in offering costs). The Company determined that an additional $0.3 million of costs incurred through June 7, 2023 related to the process of raising the proceeds generated by the issuance of the Class C Units. Accordingly, these deferred offering costs have been reclassified from other assets to mezzanine equity, for a total of $0.8 million in Class C Unit offering costs. The Class C Units were subsequently converted to AON LLC Series A Preferred Units upon the Closing of the Business Combination, which were subsequently exchanged for Series A Preferred Stock.

Professional Liability

The Company maintains insurance policies for exposure to professional malpractice insurance risk. The limits of malpractice insurance provide each physician/advanced practice provider with a dedicated $1.0 million limit per claim and a $3.0 million limit in the aggregate per policy period – on a first dollar basis, as no deductible applies. The policy further then extends coverage to the Company, by providing a $2.0 million limit per claim and a $4.0 million limit in the aggregate per policy period - on a first dollar basis, additionally, as no deductible applies. Reserves are established for estimates of the loss that will ultimately be incurred on claims that have been reported but not paid and claims that have been incurred but not reported. These reserves are established based on consultation with a third-party actuary. The actuarial valuations consider a number of factors, including historical claims payment patterns, changes in case reserves and the assumed rate of increase in healthcare costs. Management believes the use of actuarial methods to account for these reserves provides a consistent and effective way to measure these subjective accruals. However, due to the sensitive nature of this estimation technique, recorded reserves could differ from ultimate costs related to these claims due to changes in claims reporting, claims payment and settlement practices and differences in assumed future cost increases. Accrued unpaid claims and expenses that are expected to be paid within the next twelve months are classified as current liabilities and included in accrued other. All other accrued unpaid claims and expenses are classified as long-term liabilities and included in other long-term liabilities. Insurance recoveries associated with the unpaid claims are classified as long-term assets included in other assets.

Fair Value of Financial Instruments

Fair value is the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date.

Table of Contents

Accounting guidance establishes a three-level hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability on the measurement date. The three levels are defined as follows:


Level 1			Inputs to the valuation methodology are quoted prices (unadjusted) for an identical asset or liability in an active market.

Level 2			Inputs to the valuation methodology include quoted prices for a similar asset or liability in an active market or model-derived valuations in which all significant inputs are observable for substantially the full term of the asset or liability.

Level 3			Inputs to the valuation methodology are unobservable and significant to the fair value measurement of the asset or liability. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the placement of assets and liabilities being measured within the fair value hierarchy.

Our financial instruments include cash, short-term marketable securities, accounts receivable, notes receivable, accounts payable, accrued expenses, long-term debt and contractual agreements that resulted in derivative liabilities. Our nonfinancial assets such as property and equipment are not measured at fair value on a recurring basis; however, they are subject to fair value adjustments in certain circumstances, such as when there is evidence that impairment may exist.

The carrying amounts of cash, accounts receivable, accounts payable, notes receivable, and accrued expenses approximate their fair value because of the short-term maturity and highly liquid nature of these instruments. We determine the fair value of long-term debt and marketable securities based on various factors including maturity schedules and current market rates.

See Note 6 for a discussion of the Company’s Level 1 and Level 2 Marketable Securities as of December 31, 2023 and 2022. See below for a discussion of the Company’s Level 1 and Level 3 warrant liabilities as of December 31, 2023. As of December 31, 2023 and 2022, there were no Level 3 financial instruments. There were no transfers between any levels of the hierarchy during any periods presented.

Warrant Liabilities

The Company evaluated the Public Warrants and Private Placement Warrants and the Class B Prefunded Warrants, collectively referred to herein as “Warrants”, in accordance with ASC 815-40, “Derivatives and Hedging —- Contracts in Entity’s Own Equity”, and concluded that a provision in the warrant agreements related to potential net cash settlement of the warrants upon an exchange or tender offer that may not result in a change in control of the entity precludes the warrants from being accounted for as components of equity. As the Warrants meet the definition of a derivative as contemplated in ASC 815, the Warrants are recorded as long term liabilities on the consolidated balance sheets and measured at fair value at inception and at each reporting date in accordance with ASC 820, “Fair Value Measurement”, with changes in fair value recognized in other income (expense), net on the consolidated statements of operations and comprehensive loss in the period of change.

As of December 31, 2023, the Public Warrants were trading separately from the Class A Common Stock and the quoted market price was used to establish fair value. As such, the Public Warrants fair value was determined using a Level 1 input. The fair value of the Public Warrants is $1.9 million and recorded in other long-term liabilities on the consolidated balance sheets.

Table of Contents

Management has utilized the public warrant price to value the private warrants and believes the public and private warrants have materially consistent fair values given the existence of the make-whole redemption feature. As of December 31, 2023, a valuation of the private warrants was performed which confirmed the private warrant value was materially consistent with the public warrants. The details of this valuation are included in the paragraph below.

The fair value of the Private Placement warrants was determined using Level 3 inputs. As of December 31, 2023, the fair value of the Private Placement Warrants was estimated to be $1.4 million and recorded in other long-term liabilities on the consolidated balance sheets. The fair value was estimated at December 31, 2023, using the Black-Scholes Option Pricing model using the following assumptions:

Expected annual dividend yield – 0.0%

Expected volatility – 20.50%

Risk-free rate of return – 3.84%

Expected Option Term – 5 years

The AON Class B Prefunded Warrants are exercisable into one share of New AON Class B Common Stock. A share of New AON Class B Common Stock, together with an AON LLC Common Unit, may be exchanged for one share of New AON Class A Common Stock. Considering New AON Class B Common Stock has no economic rights and limited liquidity or value if the holder does not also possess an AON LLC Common Unit, and because the AON Class B Prefunded Warrants are exercisable into New AON Class B Common Stock, the Company has estimated fair value of the Class B Prefunded Warrants to be immaterial.

Earnings Per Share

The Company recast Historical AON LLC Equity as AON Inc. common equity for all periods prior to the Reverse Recapitalization, refer to Note 2. However, as 100% of the net losses of AON LLC prior to the Reverse Recapitalization were absorbed by the Legacy AON Stockholders, basic and diluted earnings (loss) per share is zero for the year ended December 31, 2022 and 2021 and basic and diluted earnings (loss) per share for the year ended December 31, 2023 represents only the period from September 21, 2023 to December 31, 2023, the period where the Company had earnings (loss) attributable to Class A Common Stockholders. Class B Common Stock does not have economic rights in AON Inc., including rights to dividends or distributions upon liquidation, and as a result, is not considered a participating security for basic and diluted earnings (loss) per share. As such, basic and diluted earnings (loss) per share of Class B Common Stock has not been presented.

As discussed in Note 1, the Company has issued and outstanding Sponsor Earnouts, which are subject to forfeiture if the achievement of certain stock price thresholds are not met. In accordance with ASC Topic 260, “Earnings Per Share,” the Sponsor Earnouts are excluded from weighted-average shares outstanding to calculate basic earnings (loss) per share as they are considered contingently issuable shares due to their potential forfeiture. Sponsor Earnouts will be included in weighted-average shares outstanding to calculate basic earnings (loss) per share as of the date of their stock price thresholds are met and they are no longer subject to forfeiture.

Basic and diluted earnings (loss) per share is computed by use of the two-class method as a result of outstanding Series A Preferred Stock, which accrue dividends at the annual rate of 8% of the original price per share, participate with common stock on all other dividends, and accordingly have participation rights in undistributed earnings as if all such earnings had been distributed during the period (see Note 16). Under such method income available to common stockholders is computed by deducting both dividends declared or, if not declared, accumulated on Series A Preferred Stock from net income. Loss attributable to common stockholders is computed by increasing net loss by such dividends. Since the participating Series A Preferred Stock has no contractual obligation to share in the losses of the Company, there is no loss allocation between Class A Common Stock and Series A Preferred Stock.

Basic earnings (loss) per share is based on the weighted-average number of shares of Class A Common Stock outstanding during the period. Diluted earnings (loss) per share is based on the weighted-average number of shares

Table of Contents

of Class A Common Stock used for the basic earnings (loss) per share calculation, adjusted for the dilutive effect of the Public and Private Warrants and Sponsor Earnout, if any, using the “treasury stock” method and the convertible Series A Preferred Stock and, exchangeable Class B Common Stock and Class B Prefunded Warrants, if any, using the “if-converted” method. Net earnings (loss) for diluted loss per share is adjusted for the Company’s share of AON LLC’s consolidated net earnings (loss), net of AON Inc. taxes, after giving effect to the Class B Common Stock and Class B Prefunded Warrants that are exchanged into potential shares of Class A Common Stock, Public and Private Warrants that are liability classified, and Series A Preferred Stock, to the extent it is dilutive.

Recently Adopted Accounting Pronouncements

In June 2016, the FASB issued ASU 2016-13, ‘‘Financial instruments-Credit Losses’’ (“ASU 2016- 13”). ASU 2016-13 requires entities to report ‘‘expected’’ credit losses on financial instruments and other commitments to extend credit rather than the current ‘‘incurred loss’’ model. These expected credit losses for financial assets held at the reporting date are to be based on historical experience, current conditions, and reasonable and supportable forecasts. This ASU will also require enhanced disclosures relating to significant estimates and judgments used in estimating credit losses, as well as the credit quality. ASU 2016-13 is effective for the Company for annual reporting periods beginning after December 15, 2022. ASU 2016-13 was adopted by the Company effective January 1, 2023 with no material impact on the Company’s consolidated financial statements and related disclosures.

On January 1, 2022, the Company adopted ASU 2016-02, “Leases” (Topic 842), using the modified retrospective approach for leases that existed on January 1, 2022. ASC 842 requires lessees to recognize assets and liabilities for most leases.

The Company elected to adopt the leasing package of practical expedients, which provides for not retroactively reassessing: i) any expired or existing contracts containing leases under the new definition of a lease; ii) the lease classification for any expired or existing leases; and iii) initial direct costs for any expired or existing leases. The Company also elected to adopt practical expedients around land easements and the combination of lease and non-lease components for its real estate leases. These practical expedients were applied consistently to all applicable leases.

Upon adoption of ASC 842, the Company recorded an initial adjustment to the opening balance sheet of $44.4 million to operating ROU assets, ($1.2) million to prepaid expenses and other current assets, $8.0 million to current portion of operating lease liabilities, $38.0 million to long-term operating lease liabilities, $2.5 million in ROU assets and lease liabilities related to the Company’s finance leases; and $2.8 million to other long-term liabilities. The impact of ASC 842 was not material to the consolidated statements of operations and comprehensive loss.

Recently Issued Accounting Pronouncements

In October 2021, the FASB issued ASU 2021-08, “Business Combinations: Accounting for Contract Assets and Contract Liabilities from Contracts with Customers”, which provides that an acquirer must recognize, and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606. The guidance is effective for the Company for annual reporting periods beginning after December 15, 2023, with early adoption permitted. The Company does not expect the adoption of this standard to have a material impact on the consolidated financial statements and related disclosures.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting-Improvements to Reportable Segment Disclosures. This update enhances disclosure requirements through enhanced disclosures about significant reportable segment expenses and other segment disclosures under ASC 280. This update is applicable to all public entities and is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal periods commencing after December 15, 2024. Early adoption is permitted. The amendments in this update should be applied retrospectively for all periods presented in the financial statements. The Company is currently evaluating the impact the new accounting guidance will have on the disclosures within its consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes-Improvements to Income Tax Disclosures, an update which enhances income tax disclosures. This guidance requires disaggregated information about an entity’s effective tax rate reconciliation as well as information on income taxes paid. This update is applicable to all public entities and is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments in this update should be applied prospectively; however, retrospective application is permitted. The Company is currently evaluating the impact the new accounting guidance will have on the disclosures within its consolidated financial statements.

3.Reverse Recapitalization

As discussed in Note 1, AON LLC merged with DTOC, with AON LLC surviving the Merger. AON LLC is governed by a board of managers composed of three (3) persons that were designated by New AON and two (2) persons that were designated by holders of a majority of the AON LLC Common Units, held by members of AON LLC other than New AON. Management determined AON LLC was not a variable interest entity (Refer to Note 2), and as result, identified AON LLC as the accounting acquirer of the Merger in accordance ASC Topic 805. Management concluded that AON LLC was the accounting acquirer due to (i) the Legacy AON Stockholders, defined as the former AON Class A, Class A-1, and Class B unit holders, receiving the largest portion of the voting rights in the combined company, New AON, (ii) significantly all of the Legacy AON Stockholders retained their equity interest as stockholders in New AON, (iii) AON LLC’s operations prior to the Reverse Recapitalization comprising the only ongoing operations of New AON, (iv) the Legacy AON Stockholders have the right to appoint a majority of the directors of New AON, (v) the executive management of AON LLC will become the executive management of New AON and (vi) AON LLC is significantly larger than New AON in terms of revenue, total assets, and employees. Therefore, the Merger was accounted for as a reverse recapitalization, with no goodwill or other intangible assets recorded, in accordance with ASC Topic 805. New AON was treated as the “acquired” company for financial reporting purposes, and for accounting purposes, the Reverse Recapitalization was treated as the equivalent of AON LLC issuing stock for the net assets of New AON, accompanied by a recapitalization. The net assets of New AON were recorded at historical cost on the consolidated balance sheet as of September 20, 2023, the Closing Date of the Reverse Recapitalization, with no goodwill or other intangible assets recorded. For additional information on the capitalization of New AON and AON LLC immediately following the Closing of the Reverse Recapitalization, see Notes 1 and 2.

The following table provides the historical cost of assets and liabilities of AON Inc. as of September 20, 2023.


	As of September 20, 2023
Cash and Cash Equivalents	$	1,493
Current Liabilities	(13,295)
Long Term Liabilities	(6,791)
Total Net Liabilities	$	(18,593)

The Company recorded a Day 1 expense as of the Closing of the Business Combination equal to $18.2 million. Of that total amount, $13.0 million was recorded in transaction expenses on the consolidated statement of operations and comprehensive loss. The remaining $5.2 million was recorded in other income (expense) net on the consolidated statement of operations and comprehensive loss. This amount represented the loss on the issuance of Public and Private Warrants, as of the Closing, net of cash received. The Company also recorded a $4.3 million gain in other income (expense), net related to the change in the fair value of the Public and Private Warrants during the period of September 21, 2023 through September 30, 2023.

4.Variable Interest Entities

AOMC is a wholly owned subsidiary of AON LLC and neither AOMC nor AON LLC has ownership interest in AON Partners and Partners of Maryland. Both AON Partners and Partners of Maryland are fully owned by

Table of Contents

physicians. AON LLC operates its physician practices through the MSAs and other contractual agreements between AOMC, AON Partners, and Partners of Maryland. The responsibilities of AOMC include, but are not limited to, negotiating provider and payor contracts, employment and compensation decisions, billing and collections, furnishing all supplies and equipment necessary for the respective practice’s operations as well as, necessary real estate, contracting on behalf of AON Partners and Partners of Maryland, entering into leases, holding a power of attorney to perform the above activities, preparing, maintaining and administering all accounting records (including financial reporting), expense payment, and maintenance of all information systems/software. AON LLC is paid a management fee to compensate AOMC for the services provided. AON Central Services is 80% physician owned and 20% owned by AON LLC. AOMC entered into an agreement with AON Central Services, effective January 1, 2023, to provide qualified non-clinical and non-medical employees to AOMC to support the operation of the physician practices. AOMC pays a monthly management fee to AON Central Services equal to the aggregate cost of compensation, benefits and all other costs related to these employees. AON LLC invested $0.2 million in MIBA, a newly formed LLC, during the second quarter of 2023 in exchange for 56% equity ownership. The Company evaluated AON LLC’s relationship with MIBA under the VIE model and determined it was a VIE and the Company is the primary beneficiary based on its financial controlling interest.

Based on various quantitative and qualitative factors, including assessment of certain services performed and relationships held above, management has determined that AON Partners, Partners of Maryland, AON Central Services, and MIBA are all variable interest entities and AOMC is the primary beneficiary who holds the decision-making rights over the activities that most significantly impact the economic performance of AON Partners, Partners of Maryland, AON Central Services, and MIBA through the MSAs and other contractual agreements. Accordingly, the results of AON Partners, Partners of Maryland, AON Central Services, and MIBA have been consolidated with the Company for the years ended December 31, 2023, 2022, and 2021.

The assets of AON Partners, Partners of Maryland, AON Central Services, and MIBA as of December 31, 2023 and 2022, are as follows:

5.Business Combinations

2023 Acquisitions

The Company did not have any ASC 805 acquisitions during the year ended December 31, 2023.

2022 Acquisitions

During the year ended December 31, 2022, the Company entered into a purchase agreement acquiring control of Northern Arizona Hematology and Oncology on January 1, 2022 for an aggregate purchase price of less than $0.1 million. Because the acquisition of Northern Arizona Hematology and Oncology was on the first day of the fiscal period, the Company’s results for the year ended December 31, 2022 include the results of the acquired practice.

2021 Acquisitions

During 2021 the Company entered into Asset Purchase Agreements (“Transactions”) acquiring control of four (4) oncology practices. The Transactions allow the Company to expand domestic reach related to its comprehensive oncology and practice management services. As described in Note 2, the Company evaluated each of the Transactions and determined each acquisition represents a business combination. This standard also establishes principles and requirements for how the acquirer recognizes and measures in its financial statements the identifiable assets and goodwill acquired, the liabilities assumed, and any noncontrolling interest in the acquiree. ASC 805 also determines what information to disclose to enable users of the financial statements to evaluate the nature and financial effects of the business combination.

In connection with each of the Transactions, the Company acquired 100% of both the clinical and nonclinical assets of the respective seller. The clinical assets, acquired by AON Partners, primarily consist of medical supplies and drugs. Nonclinical assets, acquired by AOMC, primarily consist of tangible fixed assets and equipment. The following table summarizes the amounts of the assets acquired and consideration transferred on acquisitions disclosed in Note 1, the accounting for which is completed as of December 31, 2022. For the table below, the Company has presented the acquired locations collectively.

Table of Contents


	2021 Acquired Locations

Cash transferred upon closing	$	3,215
Assumed capital lease liabilities	1,097
Total consideration transferred	4,312

Total net assets acquired	3,762
Amount assigned to goodwill	$	550

The following table presents revenue and net income for the years ended December 31, 2022, and 2021, respectively, as if the fiscal 2022 acquisitions had occurred as of January 1, 2021, and the fiscal 2021 acquisitions had occurred as of January 2020.

The unaudited pro forma consolidated financial information is provided for informational purposes only and is not necessarily, and should not be assumed to be, an indication of the results that would have been achieved had the transactions been completed as of the dates indicated or that may be achieved in the future. The Company did not have any material, nonrecurring pro forma adjustments directly attributable to the business combinations included in the reported pro forma revenue and net income.


	Pro Forma
	Year Ended December 31,
	2022		2021
Revenue	$	1,149,670	$	1,033,187
Net income	$	2,589	$	1,289

From the dates of acquisition through December 31, 2022 and December 31, 2021, revenue attributable to 2022 and 2021 acquired businesses was $22.9 million, and $55.7 million, respectively. It was impracticable to determine the effect on the Company’s net income (loss) of the acquired businesses as their operations have been integrated into the Company’s ongoing operations since the dates of acquisition.

In connection with each of the Company’s business combinations, the Company executed employment agreements with the selling physicians to become employees of AON Partners and/or Partners of Maryland. Additionally, for each transaction the Company and selling physicians entered into a separate unwind agreement granting each other a unilateral option that may be exercised by either party and effectively returns the acquired business to the selling physicians if exercised. In the event the Company or seller exercise their unwind rights, the selling physicians are required to repay the original purchase price for the assets that were sold in the Transaction plus any assets that were acquired after the Transaction, less any accumulated depreciation or amortization with respect to the assets. The selling physicians are also required to assume all contracts associated with their practice. Additionally, in the event of unwind, the selling physicians are entitled to any severance amounts that are due to them under their employment agreement with AON Partners and their employment is terminated on the unwind date. As of December 31, 2022, no liability has been recorded related to the unwind agreements as neither the Company nor any selling physicians exercised their unwind rights and therefore no payments are considered probable to the selling physicians. During the year ended December 31, 2023, one group of physicians exercised their unwind rights and the practice was sold on November 16, 2023 for total consideration of $1.0 million. No liability was

Credit Facilities

On April 30, 2021, the Company entered into a Loan Facility with PNC (“PNC Loan Facility”) collateralized by the Company’s assets and outstanding patient accounts receivable. The PNC Loan Facility is guaranteed on a limited basis by the Company and stockholder of AON Partners and Partners of Maryland. $34.6 million of proceeds from the PNC Loan Facility was used to pay off the Company’s previous term loans and revolver with Truist Bank. The remaining funds were made available for working capital and acquisition of additional physician practices.

The PNC Loan Facility is interest-only with total principal due at maturity on April 30, 2024. Interest originally accrued at one-month LIBOR or an alternate base rate plus 1.45%. The maximum balance of the PNC Loan Facility (“Borrowing Base”) is limited to the lesser of the Facility Limit ($65.0 million) or the fair value of the Company’s patient accounts receivable. The Company must maintain a balance of the lesser of the Borrowing Base or 65% of the Facility Limit in the first year and 75% of the Facility Limit in subsequent years (“minimum funding threshold”). The Company can repay the PNC Loan Facility up to the minimum funding threshold at any time without penalty. In accordance with the PNC Loan Facility, the Company pledged $10.0 million of collateral as restricted cash to be released quarterly in increments of $2.5 million. The restricted cash was fully released as of December 31, 2023 and 2022.

On April 30, 2021, the Company entered into a $5.0 million revolving line of credit agreement (“PNC Line of Credit”). The PNC Line of Credit has an expiration date of April 30, 2024 and originally bore interest at a rate per annum equal to the sum of the daily LIBOR rate plus 1.65% or an alternate base rate plus 0.65% and is due on the first day of each month beginning June 1, 2021. Any outstanding principal and accrued interest will be due on the expiration date. Beginning July 1, 2021, quarterly bank fees equal to 1.65% per day per annum are due in arrears and will continue on the first day of each quarter thereafter. All debt related to the PNC Line of Credit is collateralized by the Company’s assets. As of December 31, 2023 and 2022, no draws had been made on the PNC Line of Credit. The Company is also subject to a 0.20% unused line fee calculated per annum on the unused balance of the PNC Line of Credit.

On July 29, 2021, the Company amended the PNC Loan Facility increasing the Facility Limit to $75.0 million. On February 14, 2022, the Company further amended the PNC Loan Facility and Line of Credit agreements. The primary changes included an increase of the Facility limit from $75.0 million to $125.0 million, an increase of the PNC Line of Credit availability from $5.0 million to $10.0 million, interest charges to be calculated based on the Bloomberg Short-Term Bank Yield Index plus 1.65% and certain financial covenants. As part of the amendment, the Company drew an additional $16.3 million in proceeds under the Loan Facility. On August 15, 2022, the PNC Loan Facility and Line of Credit agreements were amended again to reduce the availability under the PNC Line of Credit from $10.0 million to $1.0 million.

Effective November 23, 2022, the Company entered into Waiver and Amendment No. 6 (“Waiver and Amendment”) under its PNC Loan Facility as the Company was not in compliance with the Delinquency Ratio financial covenant for the period ending October 31, 2022 and the requirement to provide certain annual financial statements. The Waiver and Amendment waives each event of default and also revised future delinquency percentages and financial statement requirements.

On June 30, 2023, the Company entered into Amendment No. 7 (“Amendment 7”) to its PNC Loan Facility which extended the maturity date from April 30, 2024 to June 30, 2026. In connection with Amendment 7, the Company paid additional debt issuance costs of $0.4 million which will be amortized over the revised remaining life of the Loan Facility. In addition, Amendment 7 revised the definition of the minimum funding threshold to limit the threshold multiplier to 65% of the Facility Limit.

On January 16, 2024, the Company entered into Amendment No. 3 (“Amendment 3”) to its PNC Line of Credit to modify certain definitions such as “change in control”. In addition, the Amendment 3 also amended certain debt covenants, such as EBITDA thresholds. The effective date of Amendment 3 is December 31, 2023.

Table of Contents

The PNC Loan Facility and PNC Line of Credit nonfinancial covenants include restrictions related to unpermitted property liens and the requirement of audited financial statements. Both agreements also contain several financial covenants, including the following ratios: accounts receivable default, delinquency, dilution, days sales outstanding, leverage, and fixed charge coverage. As of December 31, 2023, the Company was in compliance with all financial and nonfinancial debt covenants as required by both loan agreements.

Components of the net deferred tax assets and liabilities at December 31, 2023, 2022, and 2021 are as follows:


	As of December 31

As of December 31, 2023, the Company had federal and state net operating loss (“NOL”) carryforwards of $40.0 million and $38.6 million, respectively.

The federal NOL carryforwards can be carried forward indefinitely and the state NOL carryforwards begin to expire in 2028.

During the year ended December 31, 2023 and 2022, the Company recorded an increase in the valuation allowance of $11.6 million and $2.2 million, respectively. The increase is primarily related to additional tax losses generated during the year and the investment in the American Oncology Network, LLC partnership deferred tax asset recorded during the year. Since a portion of the investment in partnership deferred tax asset is considered to be capital in nature, it’s realizability is predicated on future capital gain income. Due to an insufficient history of capital gain income as well as limited projected future capital gain income, the Company has recorded a valuation allowance against the investment in partnership deferred tax asset considered to be capital in nature.

As of December 31, 2022 and 2021, there are no liabilities related to uncertain tax positions. The Company recognizes interest and penalties related to unrecognized tax liabilities as a component of income tax expense, if any.

applied to the Class A, Class A-1, and Class B Units. The historical AON LLC units disclosed in this note give effect to the conversion for all periods presented, as follows.

Class A Units

AON LLC had authorized 19,495,376 units of Class A Units, of which 19,495,376 units were issued and were outstanding as of December 31, 2022.

Class A-1 Units

AON LLC had authorized 3,000,245 units of Class A-1 Units, of which 1,842,520 units were issued and were outstanding as of December 31, 2022.

Class B Units (Profit Interest)

The Class B units were issued through the 2017 Profits Interest Plan adopted by the Company in October 2017. The Class B Units represented a non-voting equity interest in AON LLC that entitled the holder to appreciation in the equity value of AON LLC arising after the date of grant and after such time as an applicable hurdle amount is met. AON LLC recognized the cost of services received in exchange for Class B Units based on the grant-date fair value. That cost was recognized over the period during which the service provider is required to provide service in exchange for the award over the requisite service period or based on performance. AON LLC used the Black-Scholes-Merton pricing model to estimate the fair value of profits interest unit awards. On an as converted basis, as of December 31, 2022, AON LLC issued 5,614,176 Class B Units, of which 4,703,628 were vested and outstanding; the remaining 910,548 of Class B units vested upon consummation of the Business Combination. The stock compensation expense that was recognized for the vesting of the Class B Units was less than $0.1 million.

The following table summarizes the changes to AON LLC’s Class A, Class A-1, and Class B Units for the years ended December 31, 2023, 2022, and 2021.

Upon the closing of the Business Combination, the vested Class B-1 Units were reclassified to AON LLC Common Units and exchanged for newly issued shares of Class A Common Stock equal to the Per Company Unit Exchange Ratio, pursuant to the Business Combination Agreement, which resulted in the issuance of 1,047,343 shares of New AON Class A Common Stock.

Mezzanine Equity Class C Units

As described in Note 1, the AON LLC Class C Units were converted into AON LLC Series A Preferred Units as of the Closing Date. Concurrently, New AON issued a number of shares of New AON Series A Preferred Stock equal to the number of AON LLC Series A Preferred Units held by the AON Class C Preferred Investor to AEA Growth Management LP, the parent of AON Class C Preferred Investor (“AEA Growth”) in exchange for all the shares of common stock held by AEA Growth in the AON Class C Preferred Investor. Promptly after the First Step, the AON Class C Preferred Investor merged with and into New AON whereby the separate existence of the AON Class C Preferred Investor ceased and New AON held all the AON LLC Series A Preferred Units. On an as converted basis, as of September 20, 2023, 6,651,610 Series A Preferred Stock were issued to AEA Growth Management LP.

The AON LLC Class C Units were contingently redeemable convertible preferred units and classified as mezzanine equity on the consolidated balance sheet as of June 30, 2023 because the units were redeemable five years from the issuance date, at the option of the holder. As of June 30, 2023, the AON LLC Class C Units were recorded at their initial carrying value, net of offering costs. The Class C Units were not being accreted to redemption value, as the redemption was not probable due to the removal of the redemption right pursuant to the Business Combination. See discussion below.

The Class C Units had primarily, but not materially, the same rights as the Series A Preferred Stock issued by the Company to AEA Growth Management LP, the parent of the AON Class C Preferred Investor, with the exception of the “AON LLC Class C Unit Redemption Right” and the “Class C Option to Purchase Additional Shares”, discussed below. Further, the Class C Units did not contain a mandatory conversion feature that allowed AON LLC to force the Class C Investor to convert the Class C Units into another equity unit in AON LLC and the Class C Units did not have a one time conversion price adjustment.

Class C Unit Redemption Right

After the fifth anniversary of the Effective Date (June 7, 2028), the holders of a majority of the Class C Units had the right to cause the Company to redeem all of the Class C Units. The redemption price per Class C Unit was equal to the greater of (i) the Class C Liquidation Preference and (ii) the Fair Market Value of a Class C Unit (the “Class C Redemption Price”). The Class C Liquidation Preference is defined as an amount equal to the sum of (a) the Class C Preferred Return of such Class C Member and (b) the amount of such Class C Member’s Net Invested Capital Contributions of $65.0 million. The Class C Unit Preferred Return is defined as the cumulative, semiannually-compounded return of 8% per annum based on the original Net Invested Capital Contributions of $65.0 million. The Class C Unit Redemption Right was removed as of the Closing of the Business Combination.

Class C Unit Option to Purchase Additional Units

In accordance with the terms of the Amended and Restated Class C Convertible Preferred Unit Purchase Agreement dated June 7, 2023, the Class C Preferred Investor had an option to purchase an additional 378 AON Class C Units until the Closing of the Business Combination at a purchase price of $26,423 per Unit (“Option Feature”). The Company determined that this Option Feature was required to be accounted for as a derivative in accordance with ASC 815. The fair value of the derivative was estimated to be $1.4 million as of June 30, 2023. The Class C Preferred Investor did not exercise this option prior to the Closing of the Business Combination. As a

101

Table of Contents

result, the Company recognized a gain of $1.4 million in other (expense) income, net in the consolidated statements of operations and comprehensive loss for the year ended December 31, 2023. The Class C Unit Option expired as of the Closing of the Business Combination.

Series A Preferred Stock (Mezzanine Equity)

New AON Series A Preferred Stock is redeemable for cash or the value of the property, rights or securities to be paid or distributed in the event of a Deemed Liquidation Event (which outside of the Company’s control). As a result, the Company has determined that the New AON Series A Preferred Stock should be classified as mezzanine equity. At the closing of the Business Combination, the Company exchanged existing AON LLC Class C Units for Series A Preferred Stock in the Company. Based on the qualitative changes to the instrument, this exchange is considered an extinguishment for accounting purposes, with the Company recording a deemed dividend of $2.1 million to account for the difference between the carrying value of the Class C Units and the fair value of the Series A Preferred Stock at the transaction date. This amount is reflected in the consolidated statements of mezzanine and stockholders’ equity as part of the reverse recapitalization, net. See further discussion on the PIK Dividend discussed below. The Series A Preferred Stock are not being accreted to redemption value, as the Series A Preferred Stock are not redeemable, nor are they probable of becoming redeemable.

Dividends

The Series A Preferred Stock accrue dividends at a cumulative, semiannually-compounded return of 8% per annum based on the original Net Invested Capital Contributions from the Class C Units of $65.0 million. These dividends may be paid in cash or accumulate into the Accrued Value at the option of New AON. The accrual shall be calculated on June 30 and December 31 and with respect to the semiannually-compounded return, no interest is required to be paid on any present or future Series A Preferred Stock accrued dividends. The Series A Preferred Stock also participate in distributions with the Class A Common stockholders.

On September 20, 2023, the Company issued 6,651,610 Series A Preferred Stock to AEA Growth Management LP. The number of Series A Preferred Stock shares issued at the Closing of the Business Combination was equal to the aggregate Class C Liquidation Preference pursuant to the Business Combination Agreement. As a result, the issuance of the Series A Preferred Stock effectively included an in-kind payout (“PIK”) of the accrued dividend since the calculation of the amount issued was based on the Class C Liquidation Preference. As of the Closing, the Company recorded a dividend of 151,610 Series A Preferred Stock PIK shares with respect to the accrued dividends on the Series A Preferred Stock (the "PIK Dividend").

Voting

The holders of the Preferred Stock are entitled to elect and appoint one of the directors (“Series A Director”) to the Board of Directors. All other directors are appointed by the Class A and Class B Common stockholders. There are no restrictions on which matters the Series A Preferred stockholders are entitled to vote. The Series A Preferred stockholders are entitled to the number of votes equal to the number of shares of Common Stock into which the Series A Preferred Stock would be convertible on the record date of the vote.

Conversion Rights

The Series A Preferred Stock is convertible, at the option of the holder, at any time, and without the payment of additional consideration by the holder, into such number of fully-paid Class A Common Stock as is determined by dividing the Accrued Value by the Conversion Price in effect at the time of conversion (“Conversion Ratio”). The Accrued Value is the Original Issue Price (which is $10.00 per share of Preferred Stock, as adjusted for any stock split, stock dividend, combination, or other recapitalization) plus any unpaid dividends, compounded semi-annually. The Conversion Price is initially $10.00 per Preferred Share subject to adjustment for dilutive issuances of additional shares, dividends to common stockholders, stock splits, mergers, and a five-year anniversary special adjustment based on the volume weighted average price of the common stock. These dividends may be paid in cash

102

Table of Contents

or accumulate into the Accrued Value, at the option of New AON, on June 30 and December 31 of each year. The Conversion Rights shall terminate at the close of business on the day prior to the date of a Change of Control.

If at any time on or after the 30th day after the five-year anniversary of the issue date, any of the Series A Preferred Stock remain outstanding and the 30-Day VWAP of the Common Stock is less than $10.00 (as adjusted for any stock split, stock dividend, combination, or other recapitalization or reclassification), then the Conversion Price shall be adjusted to the greater of (x) the 30-Day VWAP on such date of determination and (y) $5.00 (as adjusted for any stock split, stock dividend, combination, or other recapitalization or reclassification).

New AON also has the right on or after the third-year anniversary of the date of issuance to cause all (but not less than all) of the outstanding shares of Series A Preferred Stock to be converted into shares of Class A Common Stock for each share of Series A Preferred Stock at the Conversion Ratio detailed above. The Company may only convert shares of Series A Preferred Stock into shares of Common Stock if the 30-Day VWAP of the Common Stock immediately prior to the Company Conversion Date is greater than $16.00 (as adjusted for any stock split, stock dividend, combination, or other recapitalization).

Liquidation Preferences

In the event of voluntary or involuntary liquidation, dissolution or winding up of the Company or an Initial Public Offering (IPO) or Exit Event, the Series A Preferred Stock have preferential liquidation rights. If a Deemed Liquidation Event were to occur, each Series A Preferred stockholder is entitled to be paid out of the assets of the Company available for distribution, equal to the greater of the following:

(i) The Original Issue Price of $10 per Series A Preferred Stock multiplied by the Applicable Percentage plus any Accrued Dividends on such share of Series A Preferred Stock; or

(ii) Such amount per share as would have been payable had all shares of Series A Preferred Stock been converted into Common Stock immediately prior to such Deemed Liquidation Event.

The Series A Preferred Stock Applicable Percentage is defined as a percentage equal to (a) one hundred twenty-five percent (125%) if an Exit Event, dissolution, liquidation, or winding-up occurs prior to June 7, 2024, (b) one hundred twenty percent (120%) if an Exit Event, dissolution, liquidation, or winding up occurs after June 7, 2024, but prior to June 7, 2025, (c) one hundred fifteen percent (115%) if an Exit Event, dissolution, liquidation, or winding-up occurs after June 7, 2025, but prior to June 7, 2026, (d) one hundred ten percent (110%) if an Exit Event, dissolution, liquidation, or winding up occurs after June 7, 2026, but prior to June 7, 2027, (e) one hundred five percent (105%) if an Exit Event, dissolution, liquidation, or winding-up occurs after June 7, 2027, but prior to June 7, 2028, (f) one hundred percent (100%) if an Exit Event, dissolution, liquidation, or winding-up occurs after June 7, 2028.

Distributions to Class A and Class A-1 Members

On March 4, 2020, the AON LLC entered into the Second Amended and Restated Limited Liability Agreement (“Second Operating Agreement”) which established another class of equity, Class A-1 Units. The Second Operating Agreement provided, among other things, that the Class A and A-1 Units would receive a cumulative, annually-compounded, preferred return of 8.0% and 4.0%, respectively, on capital contributions when and if distributions are declared by the Board of the Company.

Prior to the issuance of the Class C Units on June 7, 2023 as discussed above, the Class A and A-1 unitholders were paid a cash distribution of $4.0 million and $4.1 million, respectively, representing the cumulative accrued preferred return to June 7, 2023.

On June 7, 2023, in connection with the issuance of the Class C Units, AON LLC entered into the Third Amended and Restated Limited Liability Agreement (“Third Operating Agreement”) which, among other things, eliminated any provisions for future preferred returns on Class A and A-1 units.

Class A-1 Anti-Dilution Feature

Prior to the Closing, in the event AON LLC, prior to a Qualified IPO, issued additional membership equity (“Additional Issuance”) at a valuation that represents a purchase price that is less than the New Unit Purchase Price, as defined, AON LLC was obligated to issue additional Class A-1 Units, for no consideration, such that the Class A-1 unitholder maintains the same percentage ownership as prior to the Additional Issuance (“Anti-Dilution Feature”).

The Company determined that the Anti-Dilution Feature met the definition of a derivative in accordance with ASC 815. The total loss on derivatives for the year ended December 31, 2023 relating to this feature is $9.8 million, and was recorded in other (expense) income, net in the consolidated statements of operations and comprehensive loss.

As a result of the Anti-Dilution Feature, upon the issuance of the Class C Units on June 7, 2023 and the Closing of the Business Combination on September 20, 2023, the Company issued an additional 174 and 284 Class A-1 Units, that were subsequently converted into 439,176 and 718,549 AON Common Units using the Per Company Unit Exchange Ratio, pursuant to the Business Combination Agreement. The total fair value of the issuance of additional Class A-1 shares on June 7, 2023 and September 20, 2023 was $2.5 million and $7.2 million, respectively, for a cumulative $9.7 million recorded as Class A-1 member equity in the consolidated statements of mezzanine and stockholders’ equity. Upon the Closing of the Business Combination, the Class A-1 Anti-dilution Feature was eliminated and the derivative liability was fully extinguished.

16.Earnings Per Unit

The following table sets forth the computation of basic and diluted net loss per share of Class A Common Stock and represents the period from September 21, 2023 to December 31, 2023, the period where the Company had Class A and Class B common stock outstanding. Class B Common Stock does not have economic rights in AON Inc., including rights to dividends or distributions upon liquidation, and as a result, is not considered a participating security for basic and diluted loss per share. As such, basic and diluted loss per share of Class B Common Stock has not been presented. Series A Preferred Stock are considered participating securities for basic and diluted loss per share, but do not participate in losses. As such, basic and diluted loss per share is computed using the two-class method. For additional information, see Notes 1 and 2.

Basic loss per share is based on the weighted-average number of shares of Class A Common Stock outstanding during the period. Diluted loss per share is based on the weighted-average number of shares of Class A Common Stock used for the basic loss per share calculation, adjusted for the dilutive effect of Public and Private Warrants and Sponsor Earnouts, if any, using the “treasury stock” method and the convertible Series A Preferred Stock, Class B Common Stock, and Class B Prefunded Warrants, if any, using the “if-converted” method. Net loss for diluted loss per share is adjusted for the Company’s share of AON LLC’s consolidated net loss, net of AON Inc. taxes, after giving effect to Class B Common Stock and Class B Prefunded Warrants that are exchanged into potential shares of Class A Common Stock, Public and Private Warrants that are liability classified, and Series A Preferred Stock that accrue dividends, to the extent it is dilutive.


Net loss attributable to Class A Common Stockholders for basic and diluted earnings per share	$	(5,542,929)
Series A Preferred Cumulative Dividends	(1,492,917)
Series A Preferred Deemed Dividend	(2,089,000)
Undistributed loss for basic earnings per share	$	(9,124,846)

The following table details the securities that have been excluded from the calculation of weighted-average shares for diluted loss per share for the period presented as they were anti-dilutive. Note that the Sponsor Earnouts are excluded from the calculation of weighted-average shares for diluted loss per share as the contingency had not been met as of the period end.


Series A Preferred Stock			6,651,610
Class B Common Stock			25,109,551
Class B Prefunded Warrants			3,000,245
Public and Private Warrants			14,450,833

17.Noncontrolling Interest

Legacy AON Stockholders own 28,109,796 AON LLC Common Units, equal to a 67.8% of the economic interest in AON LLC. Legacy AON Stockholders also own 25,109,551 shares of Class B Common Stock and 3,000,245 Class B Prefunded Warrants, which, together with the AON LLC Common Units, may be redeemed at the option of the Legacy AON Stockholder on a one-for-one basis for shares of Class A Common Stock or the cash equivalent thereof (based on the market price of the shares of Class A Common Stock at the time of redemption) as determined by New AON. If New AON elects the redemption to be settled in cash, the cash used to settle the redemption must be funded through a private or public offering of Class A Common Stock no later than ten (10) business days after the redemption notice date. Upon the redemption of the AON LLC Common Units and Class B

Common Stock for shares of Class A Common Stock or the equivalent thereof, all redeemed shares of Class B Common Stock will be cancelled. The redemption value is determined based on a five-day volume weighted average price (”VWAP”) of the Class A common shares, subject to customary conversion rate adjustments for share splits, share dividends, and similar events affecting Class A Common Stock.

When applying SEC guidance concerning mezzanine classification, the Company understands that due to the NCI holders having control of the Board, if there is a sequence of remotely possible events that could trigger a redemption, this requires the instrument to be classified as temporary equity, without any regard to probability. Accordingly, though the redemption would require such a remotely possible sequence of events, and such remote sequence of events would also require, in management’s view, the Company to take extraordinary actions in order to allow such sequence of events to be remotely possible, the noncontrolling interest is currently classified as temporary equity. In the event that the Legacy AON Stockholders own less than 50% of the outstanding economic interest in AON LLC Common Units due to future redemptions, the noncontrolling interest will be presented as permanent equity.

The redeemable noncontrolling interest is recognized at the greater of (1) its initial fair value plus accumulated earnings/(losses) associated with the noncontrolling interest or (2) the redemption value as of the balance sheet date. At December 31, 2023, the redeemable noncontrolling interest was recorded based on its redemption value of $167.0 million which was greater than its carrying value by $160.7 million. This measurement adjustment decreased additional paid in capital by $17.6 million and retained earnings (deficit) by $143.1 million.

The following table summarizes the economic ownership of AON LLC, for the period beginning September 20, 2023, the Closing Date of the Reverse Recapitalization, and ending December 31, 2023 (Refer to Note 1).

(1) The 6,692,979 of AON Inc. Common Units issued as of the Reverse Recapitalization excludes 2,839,375 units, which is equivalent to the number of Sponsor Earnout Shares, that do not participate in profits and losses and are not included in the controlling interest percentage.

(2) As discussed in Note 15, Series A Preferred Stock are considered participating securities for basic and diluted loss per share, but do not participate in losses. As a result, the consolidated net loss of AON LLC, during the period of September 21, 2023 through December 31, 2023, were allocated to the NCI to reflect the absorption of the Legacy AON Stockholders to a portion of the consolidated net loss of AON LLC. Net losses were not attributed to Series A Preferred Stock.

18.Commitments and Contingencies

Florida Cancer Specialists Service

In October 2017, the Company entered into a Services Agreement (“Agreement’) with Florida Cancer Specialists, P.L. (“FCS”). FCS provides certain medical services and practice management and administration services to the various physician practices. These services included but were not limited to insurance billing, collections, accounts payable, purchasing, payroll processing, and compliance and coding support. The initial agreement had a five-year term which renewed annually unless either party terminated with twelve months written notice. Fees for services were based on a percentage of full-time equivalent (“FTE”) revenue, as defined, subject to a maximum percentage per FTE at defined revenue levels. For the year ended December 31, 2021, AON Partners and Partners of Maryland collectively incurred costs of approximately $4.7 million related to this Agreement which are included in general and administrative expenses in the consolidated statements of operations and comprehensive loss. As additional security for payments under the Agreement, AON LLC deposited $1.0 million with FCS. During 2021, the agreement was terminated, and the Company settled with FCS.

Contingencies

The Company, through its arrangements with certain contracts, is subject to the Medicare and Medicaid fraud and abuse laws which prohibit, among other things, any false claims, or any bribe, kick- back or rebate in return for the referral of Medicare and Medicaid patients. Violation of these prohibitions may result in civil and criminal penalties and exclusion from participation in the Medicare and Medicaid programs. Management has implemented policies and procedures they believe will assure that the Company is in substantial compliance with these laws. From time to time, the Company may receive requests for information from government agencies pursuant to their regulatory or investigational authority. Such requests can include subpoenas or demand letters for documents to assist the government in audits or investigations. Management believes that the outcome of any of these investigations would not have a material adverse effect on the Company.

Laws and regulations governing the Medicare program are complex and subject to interpretation. The Company believes that it is complying in all material respects with all applicable laws and regulations and is not aware of any pending or threatened investigations involving allegations of potential wrongdoing that would have a material effect on the Company’s consolidated financial statements. Compliance with such laws and regulations can be subject to future government review and interpretation, as well as significant regulatory action including fines, penalties, and exclusion from the Medicare Program.

The Company and its affiliates are subject to various legal proceedings and claims arising in the normal course of their business. In the opinion of management, the amount of the ultimate liability, if any, with respect to these lawsuits and claims will not have a material effect on the consolidated financial statements of the Company.

19.Professional Liability Insurance

The Company has purchased claims-made professional liability insurance coverage through December 31, 2023 and 2022, covering up to $1.0 million per incident and $3.0 million in annual aggregate for each physician and covering up to $2.0 million per incident and $4.0 million in the aggregate at the entity level. The policy does not require a deductible per incident. As of December 31, 2023 and 2022, the gross malpractice insurance recovery balance was $2.8 million and $2.2 million, respectively, and the malpractice insurance reserve liability balance totaled $4.7 million and $3.7 million, respectively. The Company has a net retail liability of approximately $1.9 million and $1.6 million, respectively, for claims arising from incidents prior to December 31, 2023 and 2022 that are not yet reported as of December 31, 2023 and 2022.

20.Subsequent Events

Subsequent to December 31, 2023, under the Company’s 2023 Incentive Equity Plan, which was adopted by the Board of Directors and approved by stockholders in connection with the Business Combination, the Company granted 3.5 million shares of Common Stock in the form of restricted stock units (“RSUs”) to employees. The RSUs are valued using the closing price of a share of the Company’s Common Stock on the grant date. Portions of the RSUs granted subsequent to December 31, 2023 vested immediately on the grant date and remaining portions will vest over one to two years following the grant date. Approximately 1.8 million shares vested during the three months ended March 31, 2024 resulting in a total vest date value of $10.5 million, and 0.5 million shares were

107

Table of Contents

withheld to cover withholding taxes of approximately $3.2 million. The weighted average grant date fair value of the RSUs was $5.75 per share and the Company expects to record a stock-based compensation charge of approximately $11.9 million related to these RSUs during the three months ended March 31, 2024.

Not applicable.

Item 9A. Controls and Procedures

Management’s Evaluation of our Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2023. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, mean controls and other procedures of a company that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company on the reports that it files or submits under the Exchange Act is accumulated and communicated to management, including, our principal executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure.

Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of December 31, 2023, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were not effective due to the material weaknesses described below.

Discussion of Previously Reported Material Weaknesses

A material weakness is a deficiency, or combination of deficiencies, in our internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim consolidated financial statements would not be prevented or detected on a timely basis.

We previously identified material weaknesses in our internal control over financial reporting. We have concluded that these material weaknesses continue to exist as of December 31, 2023.

The material weaknesses that AON identified were as follows:

with (i) an appropriate level of accounting knowledge, training and experience to appropriately analyze,

record and disclose accounting matters timely and accurately, and (ii) an appropriate level of knowledge

and experience to establish effective processes and controls. Additionally, the lack of a sufficient

complement of resources resulted in an inability to consistently establish appropriate authorities and

responsibilities in pursuit of its financial reporting objectives, as demonstrated by, among other things,

insufficient segregation of duties in its finance and accounting functions.

These material weaknesses contributed to the following additional material weaknesses:

109

Table of Contents

Company did not design and maintain controls over the preparation and review of account reconciliations and journal entries, including maintaining appropriate segregation of duties.

•The Company did not design and maintain effective controls to achieve complete, accurate, and timely accounting of accrued liabilities.

•The Company did not design and maintain effective controls to achieve complete, accurate, and timely accounting of revenue and accounts receivable. Specifically, the Company did not design and maintain controls over the inputs, assumptions, and calculations to develop our contractual allowances.

Remediation Activities

•Management continues to enhance its review process for unusual, non-routine or complex transactions;

•During 2023, management collaborated with outside consultants possessing significant financial reporting and internal control expertise to perform an extensive review of the design of the Company's internal controls over financial reporting. This review included a control design gap analysis and the development of corresponding remediation plans for control design gaps identified. These control design gaps and corresponding remediation plans included, but were not limited to, the following: improvements to the financial close and reporting process, accounting for contractual allowances related to revenue recognition, the identification of related party transactions, and the timely development of quality estimates related to accrued liabilities;

•The Company enhanced its financial close process by introducing additional layers of independent reviews by appropriately qualified individuals and improving the precision and timeliness of reviews applied to various period-end activities and financial result analyses, including journal entries and account reconciliations. Additionally, the Company is developing evidence of review standards to be consistently applied to its various period-end control activities going forward, thereby requiring control owners to formally document the operation of these controls; and

•The Company continues to design and implement a broad suite of ITGCs over change management, the review and update of user access rights and privileges, controls over batch jobs and data backups, and program development approvals and testing. During 2024, the Company intends to continue improving

110

Table of Contents

its ITGC environment by more uniformly applying password parameter requirements across its base of IT applications that are significant to its financial reporting objectives, as well as by enhancing the precision of its periodic user access reviews for these systems.

AON has begun the process to remediate its identified material weaknesses as detailed above. While significant progress has been made to enhance our internal control over financial reporting, we are still in the process of implementing, documenting and testing these processes, procedures and controls. These remediation activities are being done in conjunction with our adoption of the requirements Section 404 of the Sarbanes-Oxley Act for the year ended December 31, 2024. We will continue to devote significant time and attention to these remediation efforts. However, the material weaknesses cannot be considered remediated until the applicable remedial controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively.

Notwithstanding the material weaknesses, management has concluded that the financial statements included elsewhere in this Annual Report present fairly, in all material respects, our financial position, results of operations and cash flows in conformity with GAAP.

Management’s Annual Report on Internal Control over Financial Reporting

This Annual Report on Form 10-K does not include a report of management’s assessment regarding internal control over financial reporting pursuant to Section 215.02 of the SEC Division of Corporation Finance’s Regulation S-K Compliance & Disclosure Interpretations as it relates to reverse acquisitions between an issuer and a private operating company when it is not possible to conduct an assessment of the private operating company’s internal control over financial reporting in the period between the consummation date of the reverse acquisition and the date of management’s assessment of internal control over financial reporting required by Item 308(a) of Regulation S-K.

As discussed elsewhere in this Annual Report on Form 10-K, we completed the Business Combination on September 20, 2023, pursuant to which we acquired American Oncology Network, LLC. Prior to the Business Combination, we were a special purpose acquisition company formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, recapitalization, reorganization, or similar business combination with one or more businesses. As a result, previously existing internal controls are no longer applicable or comprehensive enough as of the assessment date as our operations prior to the Business Combination were insignificant compared to those of the consolidated entity post-Business Combination. The design of internal control over financial reporting for the Company post-Business Combination has required and will continue to require significant time and resources from management and other personnel.

They are not intended to provide factual information about any of the parties thereto or any subsidiaries of the parties thereto. The assertions embodied in those representations, warranties, and covenants were made for purposes of each of the agreements, solely for the benefit of the parties thereto.

In addition, information in any such representations, warranties, or covenants may change after the dates covered by such provisions, which subsequent information may or may not be fully reflected in the public disclosures of the parties.
