PART I

ITEM 1. BUSINESS

OVERVIEW

Bio-Techne and its subsidiaries, collectively doing business as Bio-Techne Corporation (“Bio-Techne”, “we”, “our”, “us” or the “Company”), develop, manufacture and sell life science reagents, instruments and services for the research, diagnostics and bioprocessing markets worldwide. Our broad product portfolio and application expertise enables scientific investigations into biological processes and molecular diagnostics, revealing the nature, diagnosis, etiology and progression of specific diseases. Our products aid in drug discovery efforts and provide the means for accurate clinical tests and diagnoses.

We manage the business in two operating segments – our Protein Sciences segment and our Diagnostics and Spatial Biology segment. Our Protein Sciences segment is a leading developer and manufacturer of high-quality biological reagents used in all aspects of life science research, diagnostics and cell and gene therapy. This segment also includes proteomic analytical tools, both manual and automated, that offer researchers and pharmaceutical manufacturers efficient and streamlined options for protein analysis, automated western blot, and multiplexed ELISA workflows. Our Diagnostics and Spatial Biology segment develops and manufactures diagnostic products, including controls, calibrators, and diagnostic assays for the regulated diagnostics market, advanced tissue-based in-situ hybridization assays and instrumentation for spatial genomic and tissue biopsy analysis, and genetic and oncology kits for research and clinical applications.

We are a Minnesota corporation with our global headquarters in Minneapolis, Minnesota. We were founded in 1976 as Research and Diagnostic Systems, Inc. We became a publicly traded company in 1985 through a merger with Techne Corporation, now Bio-Techne Corporation. Our common stock is listed on the NASDAQ under the symbol “TECH.” We operate globally, with offices in many locations throughout North America, Europe and Asia. Today, our product lines include hundreds of thousands of diverse products, most of which we manufacture ourselves in multiple locations in North America, as well as locations in the U.K., Canada, Switzerland and China.

We have implemented a disciplined strategy to accelerate growth in part by acquiring businesses and product portfolios that leveraged and diversified our existing product lines, filled portfolio gaps with differentiated high growth businesses, and expanded our geographic scope. A recent example includes the acquisition of Lunaphore SA (“Lunaphore”) at the beginning of fiscal 2024. We also completed a 19.9% investment in Wilson Wolf Corporation (“Wilson Wolf”) in fiscal 2023, and will acquire the remaining ownership in Wilson Wolf by the end of calendar year 2027, if not earlier due to its achievement of revenue or earnings before interest, taxes, depreciation, and amortization (“EBITDA”) targets. Recognizing the importance of an integrated, global approach to meeting our mission and accomplishing our strategies, we have maintained many of the brands of the companies we have acquired, but unified under a single global brand -- Bio-Techne.

We are committed to providing the life sciences community with innovative, high-quality scientific tools that allow our customers to make extraordinary discoveries and treat and diagnose diseases. We intend to build on Bio-Techne’s past accomplishments, high product quality reputation and sound financial position by executing strategies that position us to serve as the standard for biological content in the research market, and to leverage that leadership position to enter the diagnostics and other adjacent markets. Our strategic pillars include:

Grow & Leverage the Core. Through collaborations with key opinion leaders, participation in scientific discussions and societies, and leveraging our internal talent we expect to be able to convert our continued significant investment in our research and development activities to be first-to-market with quality products that are at the leading edge of life science researchers’ needs.

Capitalize on High Potential Markets. We will continue to leverage our strong balance sheet to gain access to new and differentiated technologies and products that improve our competitiveness in the current market, meet customers’ expanding workflow needs and allow us to enter adjacent markets.

Market Expansion Through Innovation & Acquisition. We will leverage our existing portfolio to expand our product offerings into novel research fields and further penetrate diagnostics and therapeutics markets. Acquisitions have, and will likely continue to play, an important role in our efforts to expand our portfolio of innovative tools and bioactive reagents, and support our initiatives to enter adjacent markets.

Deliver Best-in-Class Customer Experience. We will continue to expand our sales staff and distribution channels globally in order to increase our global presence and make it easier for customers to transact with us. We strive for every interaction to be seamless, personalized, and exceeding expectations. We aim to deeply understand customers’ wants and needs while simultaneously offering high-quality service at every touchpoint.

Develop People Through a Transformative Culture. As we continue to grow both organically and through acquisition, we are intentionally fostering an “EPIC” culture based on the ideals of Empowerment, Passion, Innovation and Collaboration. We strive to recruit, train and retain the most talented staff, who share these EPIC ideals to effectively implement our global strategies.

PROTEIN SCIENCES SEGMENT

Protein Sciences Segment Products and Markets

The Protein Sciences segment is the larger of our two segments, representing approximately 72% of our net sales in fiscal 2026. It is comprised of two divisions with complementary product offerings serving many of the same customers – the Reagent Solutions division and the Analytical Solutions division.

The Reagent Solutions division consists of specialized proteins, such as cytokines and growth factors, antibodies, small molecules, tissue culture sera and cell selection technologies traditionally used by researchers to further their life science experimental activities and by companies developing next generation diagnostics and therapeutics, including cell- and gene-based therapeutics. We believe we are the world leader in providing high quality proteins, both for research use and under current Good Manufacturing Practices, or cGMP. Key product brands include R&D Systems, Tocris Biosciences and Novus Biologicals. Our combined chemical and biological reagents portfolio provides high quality tools that customers can use in solving complex biological pathways and to glean knowledge that may lead to a more complete understanding of biological processes, and, ultimately, to the development of novel therapeutic strategies to address different pathologies. In recent years, we have made several acquisitions and investments that have expanded our product offerings for the cell and gene therapy market. These include a significant investment in state-of-the art facilities for production of both proteins and small molecules in large quantities manufactured in accordance with cGMP, as well as a 19.9% investment in, and eventual acquisition of, Wilson Wolf, a leading provider of cell culture devices for cell-based therapies. Through a collaborative marketing venture with Wilson Wolf, we have leveraged the products we have or are developing to provide a more complete offering for the cell and gene therapy market.

The Analytical Solutions division includes manual and automated protein analysis instruments and immunoassays that are used in quantifying proteins in a variety of biological fluids. Products in this division include traditional manual plate-based immunoassays, fully automated multiplex immunoassays on various instrument platforms, and automated western blotting and isoelectric focusing analysis of complex protein samples. Key product brands include R&D Systems and ProteinSimple. A number of our products have been demonstrated to have the potential to serve as predictive biomarkers and therapeutic targets for a variety of human diseases and conditions including cancer, autoimmunity, diabetes, hypertension, obesity, inflammation, neurological disorders, and kidney failure. Immunoassays can also be useful in clinical diagnostics. In fact, we have received Food and Drug Administration (FDA) marketing clearance for a few of our immunoassays for use as in vitro diagnostic devices. 

Protein Sciences Segment Customers and Distribution Methods

Our customers for this segment include researchers in academia and industry (chiefly pharmaceutical and biotech companies as well as contract research organizations). This segment also sells to diagnostic/companion diagnostic and therapeutic customers, including those engaged in the development of cell- and gene-based therapies. Our biologics line of products in the Analytical Solutions division is used chiefly by production and quality control departments at biotech

and pharmaceutical companies. We sell our products directly to customers who are primarily located in North America, Europe and China, as well as through a distribution agreement with Thermo Fisher Scientific. We also sell through third party distributors in China, Japan, certain eastern European countries and the rest of the world. Our sales are widely distributed, and no single end-user customer accounted for more than 10% of the Protein Sciences segment’s net sales during fiscal 2026, 2025, or 2024.

DIAGNOSTICS AND SPATIAL BIOLOGY SEGMENT

The Diagnostics and Spatial Biology segment, representing approximately 28% of our net revenues in fiscal 2026, includes two divisions and is focused primarily on the diagnostic and research markets and includes spatial biology, liquid biopsy, molecular diagnostics kits and products, and diagnostics reagents.

Diagnostics and Spatial Biology Segment Products

The Spatial Biology division products sold under the Advanced Cell Diagnostics, or ACD, brand, are novel in-situ hybridization (ISH) assays for transcriptome, DNA copy, and structural variation analysis within intact cells, providing highly sensitive and specific spatial information at single cell resolution. Since these products preserve spatial context, they are particularly useful for complex tissue profiling. In the first quarter of fiscal 2024, we closed on the acquisition of Lunaphore, a leading developer of fully automated spatial biology solutions using precision microfluidic technology capable of revealing hyperplex proteomic and transcriptomic biomarkers in tumors and other tissues at single-cell and subcellular resolution. Lunaphore’s COMET instrument automates ACD’s RNAscope assays and utilizes antibodies to enable simultaneous hyperplex detection of protein and RNA biomarkers on the same slide at single-cell resolution.

The Bio-Techne Diagnostic division consists of regulated products traditionally used as calibrators and controls in the clinical setting. Also included are instrument and process control products for hematology, blood chemistry, blood gases, coagulation controls and reagents used in various diagnostic applications. We often manufacture these reagents on a custom basis, tailored to a customer’s specific diagnostic assay technology. We supply these reagents in various formats including liquid, frozen, or in lyophilized form. Most of these products are sold on an Original Equipment Manufacturer (OEM) basis to instrument manufacturers, with most products being FDA-cleared. We also sell products for genetic carrier screening, oncology diagnostics, molecular controls, and research under the Asuragen brand.

Diagnostics and Spatial Biology Segment Customers and Distribution Methods

The customers for the Spatial Biology division include researchers in academia as well as investigators in pharmaceutical and biotech companies. We sell our products directly to those customers who are primarily located in North America, Europe, and China, and through distributors elsewhere. In addition to being useful research tools, our DNA and RNA in situ hybridization (ISH) assays have diagnostics applications, and several are cleared or currently under review by the FDA in partnership with diagnostics instrument manufacturers and pharmaceutical companies.

The Asuragen-branded products are sold primarily to laboratories for use in lab-developed tests or in kit form as regulated diagnostic tests. The majority of Bio-Techne Diagnostic division’s sales are through OEM agreements, but we sell some of our diagnostic reagent products directly to customers and, in Europe and Asia, also through distributors. No customer accounted for 10% or more of the reporting segment’s consolidated net sales during fiscal 2026, 2025 or 2024.

MANUFACTURING AND MATERIALS

Our manufacturing operations use a wide variety of raw materials and components, including electronic components, chemicals and biological materials. No single supplier is material, although for some components that require particular specifications or regulatory or other qualifications there may be a single supplier or a limited number of suppliers that can readily provide such components. We utilize a number of techniques to address potential disruption in and other risks relating to our supply chain, which in certain cases includes the use of safety stock, alternative materials, and qualification of multiple supply sources.

The majority of our products are shipped within one day of receipt of the customers’ orders, other than our instruments and related cartridges, which are typically shipped within one to two weeks of receipt of an order. There was no significant

Table of Contents

backlog of orders for our products as of the date of this Annual Report on Form 10-K or as of a comparable date. For additional discussion of risks relating to supply chain and manufacturing, refer to “Item 1A. Risk Factors.”

COMPETITION

Although our segments both generally operate in highly competitive markets, it is difficult to determine our competitive position, either in the aggregate or by segment, since none of our competitors offer all of the same product and service lines or serve all of the same markets as the Company or its segments. Because of the range of the products and services we sell, we encounter a wide variety of competitors, including a number of large, global companies or divisions of such companies with substantial capabilities and resources, as well as a number of smaller, niche competitors with specialized product offerings. We have seen increased competition in a number of our markets as a result of the entry of new companies into certain markets, the entry of competitors based in low-cost manufacturing locations, and increasing consolidation in particular markets. The number of competitors varies by product line. Key competitive factors vary among the Company’s businesses, but include the specific factors noted above with respect to each particular business and typically also include price, quality and safety, performance, delivery speed, application expertise, service and support, technology and innovation, distribution network, breadth of product, service and software offerings, and brand name recognition. We believe our competitive position is strong due to the unique aspects of many of our products and our product quality. For a discussion of risks related to competition, refer to “Item 1A. Risk Factors.”

SEASONALITY OF BUSINESS

Bio-Techne believes there is some seasonality as a result of vacation and academic schedules of its worldwide customer base, particularly for the Protein Sciences segment.

A majority of Bio-Techne Diagnostic division products are manufactured in large bulk lots and sold on a schedule set by the customer. Consequently, sales for that division can be unpredictable, and not necessarily based on seasonality. As a result, we can experience material and sometimes unpredictable fluctuations in our revenue from the Diagnostics and Spatial Biology segment.

GOVERNMENT CONTRACTS

Although the Company transacts business with various government entities, no government contract is of such magnitude that renegotiation or termination of the contract at the election of the government entity would have a material adverse effect on the Company’s financial results. As a party to these contracts, Bio-Techne does have to comply with certain regulations that apply to companies doing business with governments. For a discussion of risks related to government contracting requirements, see “Item 1A. Risk Factors.”

NEW PRODUCTS AND RESEARCH AND DEVELOPMENT

We believe that our future success depends, to a large extent, on our ability to keep pace with changing technologies and market needs. Bio-Techne is engaged in continuous research and development in all of our major product lines. We also carry out research to develop new products that build upon and expand the technologies we acquire through our acquisition strategy. In fiscal 2026, we introduced over 1,900 new products. While this is an area of focus for the Company, there is no assurance that any of the products in the research and development phases can be successfully completed or, if completed, can be successfully introduced into the marketplace.

PENDING MERGER WITH MERCK KGAA, DARMSTADT, GERMANY

On June 25, 2026, the Company entered into the Agreement and Plan of Merger (the “Merger Agreement”), with Merck KGaA, Darmstadt, Germany, a German corporation with general partners (“Parent”) and EMD Holdings NewCo, Inc. (“Merger Sub”), a Minnesota corporation and a wholly-owned subsidiary of Parent. The Merger Agreement provides that, upon the terms and subject to the conditions set forth therein, Merger Sub will be merged with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly-owned subsidiary of Parent. At the effective time of the Merger (the “Effective Time”), each share of our common stock (other than Company Restricted Stock (as defined in the Merger Agreement)) that is issued and outstanding immediately prior to the Effective Time (other than Excluded Shares (as defined in the Merger Agreement)) will automatically be converted into the right to receive $73.00 in cash, without

Table of Contents

any interest thereon and less any required tax withholdings and all of such shares of our common stock will cease to be outstanding and cease to exist. The Merger is expected to close by late 2026 or early 2027, subject to satisfaction of  customary closing conditions, including receipt of required regulatory approvals and approval by the Company’s shareholders. For more information, see Note 1 to our Consolidated Financial Statements as of and for the fiscal year ended June 30, 2026 and our proxy statement filed with the SEC on August 20, 2026.

HUMAN CAPITAL

Through its subsidiaries, Bio-Techne employed approximately 3,000 full-time and part-time employees as of June 30, 2026, of whom approximately 2,200 were employed in the U.S. and approximately 800 outside the U.S. None of the U.S. employees are unionized. Outside the U.S., the Company has government-mandated collective bargaining arrangements or work councils in certain countries.

Bio-Techne is committed to attracting, developing, engaging, and retaining the best people possible from around the world to sustain and grow our leadership position in life sciences tools and diagnostics. We strive to create an employee experience that allows each to achieve their full potential. This is demonstrated by our EPIC values of Empowerment, Passion, Innovation and Collaboration. We continuously build on our people-first culture, led by uncompromising integrity, hosting a place of belonging, granting access to innovation and respecting human rights around the globe.

Our people strategy spans multiple key dimensions, including the following:

Culture and Governance

Our four EPIC values of Empowerment, Passion, Innovation and Collaboration are the backbone for the way we approach the leadership and direction of our work force. Employees are empowered to realize their potential. Our culture supports and encourages a collaborative approach to working with each other and with our customers. We encourage innovation to continually improve our products, services and processes, and our passions for science and the missions of our customers are our guiding lights.

Our EPIC values are embedded in our culture and practices. To further amplify our desired behaviors, we have an annual employee recognition program in which we ask for nominations and recognize winning individuals and teams across our business who have best demonstrated our EPIC values.

Bio-Techne’s Board of Directors reviews management succession planning at least annually, and its Compensation Committee reviews the Company’s people strategy periodically in connection with significant initiatives and acquisitions, as well as part of its oversight of our executive and equity compensation programs. At the management level, our Chief Human Resources Officer, who reports directly to our President and CEO, is responsible for the development and execution of the Company’s people strategy.

Engagement and Belonging

Our engagement strategy focuses on developing the best workplace and best people leaders to meet our employees’ needs. We believe that strong employee engagement helps enable higher retention and better business performance. We assess our engagement performance through regular consultation with our managers. We also engage more formally via an annual engagement survey that assesses our employees’ overall experience. In fiscal 2026, three-fourths of our global workforce participated, and 77% of those who responded provided favorable feedback. While these responses were positive, our management used the responses to inform and shape our future employee-focused initiatives. These initiatives in the past have resulted in changes in programs and policies, including expansion of our management and leadership development programs, expansion of a parental leave program, introduction of flexible working, addition of an internal communications function, leadership engagement focused on transparency and stronger feedback follow-up, and expansion of the breadth and resources of our Employee Resource Groups (ERGs). In fiscal 2026, we empowered work/life integration through hybrid work models wherever feasible, continued to cultivate belonging and inclusion, and paved the path for career growth through the personalized development and individual action plans.

We believe a culture of belonging is central to drive innovation, fuel growth and help ensure our technologies and products effectively serve a global customer base. The Company’s executive-sponsored Belonging initiative is focused on providing

8

Table of Contents

a welcoming working environment for all employees, continued education, broadening our candidate pools, and implementing and sustaining programs. Under the guidance of our executive-sponsored Employee Resource Group Council, ERGs offer mentorship, support and engagement to help our employees succeed and thrive. As of June 30, 2026, we had 11 ERGs operating globally.

As of June 30, 2026, 48% of our total employee population was female, and 44% of our managerial employees were female. 22% of our total employee population identified as nonwhite and 20% of our managerial employees identified as nonwhite.

Recruitment and Retention

Bio-Techne believes that sustaining its profitable growth will require a continued focus on recruiting and retaining top talent. We engage in a variety of recruiting strategies intended to locate and identify qualified candidates and create a talent pipeline. The Company offers competitive pay and benefits, from flexible work to financial planning resources to an employee stock purchase plan. In recent years, we bolstered our recruitment and retention efforts by expanding eligibility to receive stock options deeper into the organization and expanded our Long-Term Incentive program strategy to include a combination of stock options and restricted stock units. Bio-Techne continues to offer a referral bonus with the understanding that this is one of our most successful sourcing methods.

In addition to pay and benefits, Bio-Techne believes that the ability to retain employees requires an environment where they can work productively and where there are opportunities to grow and advance. The Company therefore seeks to cultivate a culture of empowerment and collaboration, where employees can observe the impact of their efforts, and where they see opportunities both laterally and vertically.

The last fiscal year continued to see considerable employee mobility across all industries, including the biotechnology industry, but we nonetheless significantly reduced our attrition rate to maintain durable stability across our enterprise. We believe that Bio-Techne’s sustained efforts on recruitment and retention will fortify our resilience in the face of increased employee mobility and economic challenges.

Talent Development and Learning and Development

Bio-Techne invests in people development in the belief that growing and promoting employees from within the Company creates a more sustainable organization. High potential employees are identified through our annual talent review process, as well as through leadership development programs designed to cultivate future leaders. Employees identified as high potential are elevated to the attention of senior management for consideration for additional development, growth opportunities, and career advancement.

Our global Learning and Development program delivers a wide range of initiatives including a validated suite of compliance training, and soft, technical, business, interpersonal and career skills. Bio-Techne also encourages and supports employees who wish to supplement their growth through external training and education. As a company that regularly acquires other businesses, we believe it is important for employees to be trained in the skills and mindsets that enable them to respond positively to change. This initiative allows individuals to deal with change more easily and reduces the need to run large scale change management programs.

Well-Being and Safety

The Company is committed to protecting the physical health, safety, and psychological well-being of our employees by providing a safe work environment and permitting hybrid work schedules wherever feasible. We actively monitor and adjust our crisis management plan and response protocol to protect our employees. Bio-Techne trains all employees on foundational safety principles and requires more rigorous safety and hazard awareness training where appropriate based on function, role, or team. At Bio-Techne, all employees are empowered and encouraged to maintain and create a safe workplace. In addition, we offer internal and external resources to provide for the psychological and emotional security of employees, including employee resource programs, mental health benefit coverage, and flexible work for many roles.

Community

The Company believes in giving back and in supporting the local communities in which we live and work. The Company and its employees donate financially and by giving their time and energy. Most sites or departments engage in local charitable causes and activities. In some of our sites, employees are encouraged to give through regular payroll deductions and through the annual campaign week where employee contributions are matched by the Company. In addition, U.S. employees receive a paid day off to participate in local opportunities to give back to the community as part of our volunteer time off benefit.

INTELLECTUAL PROPERTY

Our success depends in part upon our ability to protect our core technologies and intellectual property. To accomplish this, we rely on a combination of intellectual property rights, including patents, trade secrets and trademarks, as well as customary contractual protections in our terms and conditions and other sales-related documentation.

As of June 30, 2026, we had rights to approximately 487 granted patents and approximately 230 pending patent applications. Products in the Analytical Solutions and the Spatial Biology divisions are protected primarily through pending patent applications and issued patents. In addition, certain of our products are covered by licenses from third parties to supplement our own patent portfolio. Patent protection, if granted, generally has a life of 20 years from the date of the patent application or patent grant. We cannot provide assurance that any of our pending patent applications will result in the grant of a patent, whether the examination process will require us to narrow our claims, and whether our claims will provide adequate coverage of our competitors’ products or services.

In addition to pursuing patents on our products, we also preserve much of our innovation as trade secrets, particularly in the Reagent Solutions division of our Protein Sciences segment. Where appropriate, we use trademarks or registered trademarks in connection with our products. We have taken steps to protect our intellectual property and proprietary technology, in part by entering into confidentiality agreements and intellectual property assignment agreements with our employees, consultants, corporate partners and, when needed, our advisors. See the description of risks associated with the Company’s intellectual property in “Item 1A. Risk Factors.”

We can give no assurance that Bio-Techne’s products do not infringe upon patents or proprietary rights owned or claimed by others. Bio-Techne has not conducted a patent infringement study for each of its products. Where we have been contacted by patent holders with certain intellectual property rights, Bio-Techne typically has entered into licensing agreements with patent holders under which it has the exclusive and/or non-exclusive right to use patented technology as well as the right to manufacture and sell certain patented products to the research and/or diagnostics markets.

All trademarks, trade names, product names, graphics, and logos of Bio-Techne contained herein are trademarks and registered trademarks of Bio-Techne or its subsidiaries, as applicable, in the U.S. and/or other countries. Solely for convenience, we may refer to trademarks in this Annual Report on Form 10-K without the ™ or ® symbols. Such references are not intended to indicate that we will not assert our full rights to our trademarks.

LAWS AND REGULATIONS

Our operations, and some of the products we offer, are subject to a number of complex laws and regulations governing the production, marketing, handling, transportation, and distribution of our products and services. The following sections describe certain significant regulations pertinent to the Company. These are not the only laws and regulations applicable to the Company’s business. For a description of risks related to laws and regulations to which we are subject, refer to “Item 1A. Risk Factors.”

Medical Device Regulations

A number of our products are classified as medical devices and are subject to restrictions under domestic and foreign laws, rules, regulations, self-regulatory codes and orders, including but not limited to the U.S. Food, Drug and Cosmetic Act (the “FDCA”). The FDCA requires these products, when sold in the U.S., to be safe and effective for their intended uses and to comply with the regulations administered by the U.S. Food and Drug Administration (“FDA”). The FDA regulates the design, development, testing, manufacture, advertising, labeling, packaging, marketing, distribution, import and export

10

Table of Contents

and record keeping for such products. Many medical device products are also regulated by comparable agencies in non-U.S. countries in which they are produced or sold.

Any medical devices we manufacture and distribute are subject to pervasive and continuing regulation by the FDA and certain state and non-U.S. agencies. As a medical device manufacturer, our manufacturing facilities are subject to inspection on a routine basis by the FDA. We are required to adhere to the Current Good Manufacturing Practices (“cGMP”) requirements, as set forth in the Quality Systems Regulation (“QSR”), which require manufacturers, including third-party manufacturers, to follow stringent design, testing, control, documentation and other quality assurance procedures during all phases of the design and manufacturing process.

We must also comply with post-market surveillance regulations, including medical device reporting (“MDR”), requirements which require that we review and report to the FDA any incident in which our products may have caused or contributed to a death or serious injury. We must also report any incident in which our product has malfunctioned if that malfunction would likely cause or contribute to a death or serious injury it if were to recur.

Labeling and promotional activities are subject to scrutiny by the FDA and, in certain circumstances, by the Federal Trade Commission. Medical devices approved or cleared by the FDA may not be promoted for unapproved or uncleared uses, otherwise known as “off-label” promotion. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses.

In the European Union (“EU”), our products are subject to the medical device laws of the various member states, which are currently based on a Directive of the European Commission. Additionally, the EU has adopted the In Vitro Diagnostic Regulation (the “EU IVDR”), which imposes stricter requirements for the marketing and sale of in vitro diagnostic medical devices, including in the area of clinical evaluation requirements, quality systems and post-market surveillance. Manufacturers of in vitro diagnostics medical devices that have been marketed and sold under the prior regulatory regime now have to comply with some of the new EU IVDR requirements, while the effective date of other requirements have been delayed. Complying with EU IVDR may require material modifications to our quality management systems, additional resources in certain functions, updates to technical files and additional clinical data in some cases, among other changes.

Our Asuragen business maintains a CLIA certification. Consequently, we must comply with state licensing regulations applicable to laboratories regulated under CLIA, governing laboratory practices and procedures.

Other Healthcare Laws

Some of the products and services we sell, predominantly in our Diagnostics and Spatial Biology segment, are subject to various health care related laws regulating fraud and abuse, research and development, pricing and sales and marketing practices, and the privacy and security of health information, including, among others:

For a discussion of risks related to regulation by the FDA and comparable agencies of other countries, and the other regulatory regimes referenced above, please refer to section entitled “Item 1A. Risk Factors.”

Data Privacy and Security Laws

As a global organization, we are subject to data privacy and security laws, regulations, and customer-imposed controls in numerous jurisdictions as a result of having access to and processing confidential, personal and/or sensitive data in the course of our business. In addition to the U.S. HIPAA privacy and security rules mentioned above, which impact some parts of our business, individual states also regulate data breach and security requirements, and multiple governmental bodies assert authority over aspects of the protection of personal privacy. In particular, a broad privacy law in California, the California Consumer Privacy Act (“CCPA”), came into effect in January 2020. The CCPA has some of the same features as the GDPR (discussed below) and has already prompted several other states to follow with similar laws. The EU General Data Protection Regulation that became effective in May 2018 (“GDPR”) has imposed significantly stricter requirements in how we collect, transmit, process, and retain personal data, including, among other things, in certain circumstances a requirement for almost immediate notice of data breaches to supervisory authorities and prompt notice to data subjects with significant fines for non-compliance. Several other countries in which we do business have passed, and other countries are considering passing, laws that require personal data relating to their citizens to be maintained on local servers and impose additional data transfer restrictions. For a discussion of risks related to improper disclosure of private information particularly as a result of cyber security incidents, please refer to section entitled “Item 1A. Risk Factors.”

Environmental Health and Safety Laws

We are also subject to various environmental health and safety laws and regulations both within and outside the U.S. Like other companies in our industry, our manufacturing and research activities involve the use and transportation of substances regulated under environmental health and safety laws including those relating to the transportation of hazardous materials.

Other Laws and Regulations Governing Our Sales, Marketing and Shipping Activities

We are subject to the U.S. Foreign Corrupt Practices Act and various other similar anti-corruption and anti-bribery acts, which are particularly relevant to our operations in countries where the customers are government entities or are controlled by government officials. Both directly and indirectly through our distributors, we must comply with such laws when interacting with those entities.

As Bio-Techne’s businesses also include export and import activities, including the export and import of products derived from animals, we are subject to pertinent laws enforced by the U.S. Department of Agriculture, U.S. Customers and Border Patrol, U.S. Departments of Commerce, State and Treasury. Other nations’ governments have implemented similar export/import control and economic sanction regulations, which may affect the Company’s operations or transactions subject to their jurisdictions.

In addition, under U.S. laws and regulations, U.S. companies and their subsidiaries and affiliates outside the U.S. are prohibited from participating or agreeing to participate in unsanctioned foreign boycotts in connection with certain business activities, including the sale, purchase, transfer, shipping or financing of goods or services within the U.S. or

12

Table of Contents

between the U.S. and countries outside of the U.S. If we, or certain third parties through which we sell or provide goods or services, violate anti-boycott laws and regulations, we may be subject to civil or criminal enforcement action and varying degrees of liability.

We are subject to laws and regulations governing government contracts, and failure to address these laws and regulations or comply with government contracts could cause a reduction in revenue associated with these customers. We have agreements relating to the sale of our products to government entities and, as a result, we are subject to various statutes and regulations that apply to companies doing business with the government. We are also subject to investigation for compliance with the regulations governing government contracts. A failure to comply with these regulations could result in suspension of these contracts, criminal, civil and administrative penalties or debarment.

For a discussion of risks related to the above-referenced regulations, particularly with respect to our international operations, please refer to section entitled “Item 1A. Risk Factors.”

ITEM 1A. RISK FACTORS

Set forth below are risks and uncertainties we believe are material to our investors. You should refer to the explanation of the qualifications and limitations on forward-looking statements in the section titled Information Relating to Forward-Looking Statements at the beginning of this Annual Report on Form 10-K.

Economic and Industry Risks

Conditions in the global economy, the particular markets we serve and the financial markets, whether brought about by material global crises or other factors, may adversely affect our business and financial results.

Our business is sensitive to global economic conditions. Slower economic growth in the domestic or international markets, inflation, recession, volatility in the credit and currency markets, high levels of unemployment or underemployment, labor availability constraints, public health crises, changes or anticipation of potential changes in government trade, fiscal, tax or monetary policies, government budget dynamics (particularly in the healthcare and scientific research areas), and other challenges in the global economy have in the past adversely affected, and may in the future adversely affect, the Company and its distributors, customers, and suppliers.

Without limiting the foregoing, we have experienced and/or may in the future experience:

​

​

​

​

​

​

​

If growth in the global economy or in any of the markets we serve slows for a significant period, if there is significant deterioration in the global economy or such markets or if improvements in the global economy do not benefit the markets we serve, our business and financial results can be adversely affected.

International political, compliance and business factors, including the military conflicts and trade tensions, can negatively impact our operations and financial results.

We engage in business globally, with approximately 48% of our sales revenue in fiscal 2026 coming from outside the U.S. Changes, potential changes or uncertainties in social, political, regulatory, and economic conditions or laws and policies governing foreign trade, manufacturing, and development and investment in the territories and countries where we or our customers operate, or governing the health care system, can adversely affect our business and financial results. For example, Congress and the U.S. administration have sought to impose changes to healthcare in the U.S., including government negotiation/regulation of drug prices paid by government programs. Such impacts could negatively impact certain markets we serve, resulting in an adverse impact on our sales revenue.

Political and military conflicts may disrupt our business or negatively impact global economic or business conditions. For example, Russia’s military invasion of Ukraine, and the response by the US and European countries to that invasion, have

15

Table of Contents

caused severe political, humanitarian and economic crises, not only in Europe but globally. Restrictions on trade, particularly involving certain foods and energy supplies, have increased prices, led to widespread inflation and otherwise aggravated economic challenges. While we have not historically had significant business in either Russia, Ukraine, or Israel, the broader impact of the conflict could negatively impact our operations and financial results.

One of our strategies is to expand geographically, particularly in China, India and in developing countries, both through distribution and through direct operations. This subjects us to a number of risks, including international economic, political, and labor conditions; currency fluctuations; tax laws (including U.S. taxes on foreign subsidiaries); increased financial accounting and reporting burdens and complexities; unexpected changes in, or impositions of, legislative or regulatory requirements; failure of laws to protect intellectual property rights adequately; inadequate local infrastructure and difficulties in managing and staffing international operations; delays resulting from difficulty in obtaining export licenses for certain technology; tariffs, quotas and other trade barriers and restrictions; transportation delays; operating in locations with a higher incidence of corruption and fraudulent business practices; and other factors beyond our control, including terrorism, war, natural disasters, climate change and diseases. In addition, geopolitical tensions with these countries could exacerbate these risks.

The application of laws and regulations impacting global transactions is often unclear and may at times conflict. Compliance with these laws and regulations may involve significant costs or require changes in our business practices that result in reduced revenue and profitability. Non-compliance could also result in fines, damages, criminal sanctions, prohibited business conduct, and damage to our reputation. We incur additional legal compliance costs associated with our global operations and could become subject to legal penalties in foreign countries if we do not comply with local laws and regulations, which may be substantially different from those in the U.S.

We continue to expand our operations in countries with developing economies, where it may be common to engage in business practices that are prohibited by U.S. regulations applicable to the Company, such as the Foreign Corrupt Practices Act. Although we implement policies and procedures designed to ensure compliance with these laws, there can be no assurance that all of our employees, contractors, and agents, as well as those companies to which we outsource certain aspects of our business operations, including those based in foreign countries where practices which violate such U.S. laws may be customary, will comply with our internal policies. Any such non-compliance, even if prohibited by our internal policies, could have an adverse effect on our business and result in significant fines or penalties.

The healthcare and life sciences industries that we serve face constant pressures and changes in an effort to reduce healthcare costs or increase their predictability, all of which may adversely affect our business and financial results.

Our Protein Sciences segment products are sold primarily to research scientists at pharmaceutical and biotechnology companies and at university and government research institutions. Research and development spending by our customers and the availability of government research funding can fluctuate due to changes in available resources, mergers of pharmaceutical and biotechnology companies, spending priorities, general economic conditions and institutional and governmental budgetary policies.

Our Diagnostics and Spatial Biology segment products include applications in the medical diagnostics market, which relies largely on government healthcare-related policies and funding. Changes in government reimbursement for certain diagnostic tests or reductions in overall healthcare spending could negatively impact us directly or our customers and, correspondingly, our sales to them. The process and timeline for obtaining coverage decisions is uncertain and difficult to predict, and reimbursement reductions due to changes in policy regarding coverage of tests or other requirements for payment (such as prior authorization, diagnosis code and other claims edits, or a physician or qualified practitioner’s signature on test requisitions) may be implemented from time to time. Additionally, the U.S. government’s negotiation of most favored nation pricing on certain prescription drugs, and the potential for expansion of this program, may impact the customers and industries we serve by increasing the cost of commercializing and/or limiting the profitability of commercialized products.  In addition, the potential for expanded regulation of lab developed tests may, if such regulation were implemented, also impact the customers and industries we serve by increasing the cost of commercializing and/or limiting the profitability of commercialized products. Payor actions and changes may have a material adverse effect on revenue and earnings associated with our diagnostics products and services.

Acquisition and Investment Risks

Our inability to complete acquisitions at our historical rate and at appropriate prices, and to make appropriate investments that support our long-term strategy, could negatively impact our growth rate and stock price.

One of our key strategies is growth through acquisition of other businesses and assets. Our ability to grow revenues, earnings and cash flow at or above our historic rates depends in part upon our ability to identify and successfully acquire and integrate businesses at appropriate prices and realize anticipated synergies, and to make appropriate investments that support our long-term strategy. We may not be able to consummate acquisitions at rates similar to the past, which could adversely impact our growth rate and our stock price. Promising acquisitions and investments are difficult to identify and complete for a number of reasons, including high valuations, competition among prospective buyers or investors, the availability of affordable funding in the capital markets and the need to satisfy applicable closing conditions and obtain applicable antitrust and other regulatory approvals on acceptable terms. Changes in accounting or regulatory requirements or instability in the credit markets could also adversely impact our ability to consummate acquisitions and investments.

Our acquisition of businesses, investments, joint ventures and other strategic relationships, if not properly implemented or integrated, could negatively impact our business and financial results.

As part of our business strategy, we acquire businesses, make investments and enter into joint ventures and other strategic relationships in the ordinary course of business, and we also from time to time complete more significant transactions. At the beginning of fiscal 2025, we invested in Spear Bio and, at the beginning of fiscal 2024, we completed the acquisition of Lunaphore, a leading developer of fully automated spatial biology solutions. Bio-Techne also obtained a 19.9% ownership stake in Wilson Wolf and will acquire the remaining ownership no later than the end of calendar year 2027. We have also continued participating in our collaborative marketing venture, ScaleReady LLC, with Wilson Wolf and another partner, which addresses the needs of the rapidly expanding cell and gene therapy market. While we believe these business ventures will advance our business strategies and support our growth plans, we may not be successful in managing or integrating them into our Company. Acquisitions, investments, joint ventures and strategic relationships involve a number of additional financial, accounting, managerial, operational, legal, compliance and other risks and challenges, including but not limited to the following, any of which could adversely affect our business and our financial results:

​

​

​

​

​

​

​

Table of Contents

​

​

We may be required to record a significant charge to earnings if our goodwill and other amortizable intangible assets or other investments become impaired, which could negatively impact our financial results or stock price.

We are required under generally accepted accounting principles to test goodwill for impairment at least annually and to review our goodwill, amortizable intangible assets, and other assets acquired through merger and acquisition activity for impairment when events or changes in circumstance indicate the carrying value may not be recoverable. Factors that could lead to impairment of goodwill, amortizable intangible assets, and other assets acquired via acquisitions include significant adverse changes in the business climate and actual or projected operating results (affecting our Company as a whole or affecting any particular segment) and declines in the financial condition of our business. We may be required in the future to record additional charges to earnings if our goodwill, amortizable intangible assets or other investments become impaired. Any such charge would adversely impact our financial results.

In addition, the Company’s expansion strategies include collaborations and investments in joint ventures and companies developing new products related to the Company’s business. These strategies carry risks that objectives will not be achieved and future earnings will be adversely affected.

Strategic and Operational Risks

Our success will be dependent on recruiting and retaining highly qualified and diverse personnel and creating and maintaining a culture that successfully integrates the employees joining through acquisitions.

Recruiting and retaining qualified scientific, production, sales and marketing, and management personnel representing diverse backgrounds, experiences and skill sets are critical to our success. The market for highly skilled workers and leaders in our businesses, particularly in the areas of science and technology, is extremely competitive. In fiscal 2026, a number of our businesses and departments continued to face recruitment and retention challenges, and faced labor availability constraints and inflationary costs. Our growth by acquisition also creates challenges in retaining employees. As we integrate past and future acquisitions and evolve our corporate culture to incorporate new workforces, some employees may not find such integration or cultural changes appealing. The failure to attract and retain such personnel could adversely affect our business.

Our growth depends in part on the timely development and commercialization of new and enhanced products and services that meet our customers’ needs. Our growth can also be negatively impacted if our customers do not grow as anticipated.

We generally sell our products and services in industries that are characterized by rapid technological change, frequent new product introductions and new market entrants and competitors. If we do not develop innovative new and enhanced products and services on a timely basis, our offerings will become obsolete over time and our business and financial results will suffer. Our success will depend on several factors, including our ability to:

​

​

​

​

​

​

​

​

​

If we fail to accurately predict future customer needs and preferences or fail to produce viable technologies, we may invest heavily in research and development of products that do not lead to significant revenue, which would adversely affect our business and financial results. Even when we successfully innovate and develop new and enhanced products, we often incur substantial costs in doing so, and our profitability may suffer.

We face intense competition, and if we are unable to compete effectively, we may experience decreased demand and decreased market share or need to reduce prices to remain competitive.

We face intense competition across most of our product lines. Competitors include companies ranging from start-up companies, which may be able to more quickly respond to customers’ needs, to large multinational companies, which may have greater financial, marketing, operational, and research and development resources than us. In addition, consolidation trends in the pharmaceutical, biotechnology and diagnostics industries have served to create fewer customer accounts and to concentrate purchasing decisions for some customers, resulting in increased pricing pressure on us. Moreover, customers may believe that consolidated businesses are better able to compete as sole source vendors, and therefore prefer to purchase from such businesses. The entry into the market by manufacturers in countries in Asia and other low-cost manufacturing locations is also creating increased pricing and competitive pressures, particularly in developing markets. In order to compete effectively, we must retain longstanding relationships with major customers and continue to grow our business by establishing relationships with new customers, continually developing new products and services to maintain and expand our brand recognition and leadership position in various product and service categories and penetrating new markets, including high-growth markets. Our ability to compete can also be impacted by changing customer preferences and requirements (for example increased demand for more environmentally-friendly products and supplier practices). Our failure to compete effectively and/or pricing pressures resulting from competition may adversely impact our business and financial results, and our expansion into new markets may result in greater-than-expected risks, liabilities and expenses.

A significant disruption in, or breach of security of, our information technology systems or data, or violation of data privacy laws, could result in damage to our reputation, data integrity and/or subject us to costs, fines, or lawsuits under data privacy or other laws or contractual requirements.

The integrity and protection of our own data, and that of our customers and employees, is critical to our business. We rely on information technology systems, some of which are provided and/or managed by third parties, to process, transmit and store electronic information (including sensitive data such as confidential business information and personally identifiable data relating to employees, customers, other business partners and patients), and to manage or support a variety of critical business processes and activities (such as receiving and fulfilling orders, billing, collecting and making payments, shipping products, providing services and support to customers and fulfilling contractual obligations). These systems, products and services (including those we acquire through business acquisitions) can be damaged, disrupted or shut down due to attacks by computer hackers, computer viruses, ransomware, human error or malfeasance, power outages, hardware failures, telecommunication or utility failures, catastrophes or other unforeseen events, and in any such circumstances our system redundancy and other disaster recovery planning may be ineffective or inadequate. Attacks can also target hardware, software and information installed, stored or transmitted in our products after such products have been purchased and incorporated into third-party products, facilities or infrastructure. Security breaches of systems provided or enabled by us, regardless of whether the breach is attributable to a vulnerability in our products or services, or security breaches of third party systems we rely on to process, store or transmit electronic information, can result in the misappropriation, destruction or unauthorized disclosure of confidential information or personal data belonging to us or to our employees, partners, customers, patients or suppliers. These attacks, breaches, misappropriations and other disruptions and damage can interrupt

19

Table of Contents

our operations or the operations of our customers and partners, delay production and shipments, result in theft of our and our customers’ intellectual property and trade secrets, result in disclosure of personally identifiable information, damage customer, patient, business partner and employee relationships and our reputation and result in defective products or services, legal claims and proceedings, liability and penalties under privacy laws and increased costs for security and remediation, in each case resulting in an adverse effect on our business and financial results.

In addition, our information technology systems require an ongoing commitment of significant resources to maintain and enhance existing systems and develop or integrate new systems to keep pace with continuing changes in information processing technology, evolving legal and regulatory standards, evolving customer expectations, changes in the techniques used to obtain unauthorized access to data and information systems, and the information technology needs associated with our changing products and services. There can be no assurance that we will be able to successfully maintain, enhance and upgrade our systems as necessary to effectively address these requirements.

If we are unable to maintain reliable information technology systems or appropriate controls with respect to global data privacy and security requirements and prevent data breaches, we may suffer regulatory consequences in addition to business consequences. As a global organization, we are subject to data privacy and security laws, regulations, and customer-imposed controls in numerous jurisdictions as a result of having access to and processing confidential, personal and/or sensitive data in the course of our business. Individual states regulate data breach and security requirements, and multiple governmental bodies assert authority over aspects of the protection of personal privacy. Most notably, an increasing number of states, including California, Virginia, Utah, Colorado and Connecticut, have passed broad privacy legislation that could result in more material impacts as implementing regulations are issued. European laws require us to have an approved legal mechanism to transfer personal data out of Europe. Failure to comply with the requirements of GDPR and the applicable national data protection laws of the EU member states may result in fines of up to €20 million or up to 4% of the total worldwide annual turnover of the preceding financial year, whichever is higher, and other administrative penalties. Several other countries such as China and Russia have passed, and other countries are considering passing, laws that require personal data relating to their citizens to be maintained on local servers and impose additional data transfer restrictions. Government enforcement actions can be costly and interrupt the regular operation of our business, and data breaches or violations of data privacy laws can result in fines, reputational damage and civil lawsuits, any of which may adversely affect our business, reputation and financial results.

If we suffer loss to our supply chains, distribution systems or information technology systems due to catastrophe or other events, our operations could be seriously harmed.

Our supply chains, distribution systems and information technology systems may be subject to catastrophic loss due to fire, flood, earthquake, hurricane, power shortage or outage, public health crisis (including epidemics and pandemics) and the reaction thereto, war, terrorism, riot or other man-made or natural disasters. If any of these supply chains or systems were to experience a catastrophic loss, it could disrupt our operations, delay production and shipments, result in defective products or services, diminish demand, damage customer relationships and our reputation and result in legal exposure and significant repair or replacement expenses. The third-party insurance coverage that we maintain varies from time to time in both type and amount depending on cost, availability and our decisions regarding risk retention, and may be unavailable or insufficient to protect us against such losses.

The manufacture of many of our products is a complex process, and in many cases subject to complex regulations, and if we directly or indirectly encounter problems manufacturing products, our business and financial results could suffer.

The manufacture of many of our products is a complex process, due in part to strict regulatory requirements for some of our products. Problems can arise during manufacturing for a variety of reasons, including equipment malfunction, failure to follow specific protocols and procedures, problems with reliable sourcing of raw materials or components, natural disasters and environmental factors, and, if not discovered before the product is released to market, can result in recalls and product liability exposure. Because of the quality requirements of some of our customers as well as stringent regulations of the FDA and similar agencies regarding the manufacture of certain of our products, alternative manufacturing or sourcing is not always available on a timely basis to replace such production capacity. Any of these manufacturing problems could result in significant adverse impacts to our business and financial results.

20

Table of Contents

For instance, our use of animal-derived materials in certain products and manufacturing processes subjects us to regulatory, supply chain, quality, and reputational risks that could adversely affect our business. The sourcing, processing, importation, exportation, handling, storage, transportation and use of animal-derived materials are subject to complex and evolving laws, regulations and governmental oversight, including requirements administered by the USDA, APHIS, and the FDA, as well as customs authorities and comparable regulatory agencies in foreign jurisdictions. Changes in applicable regulations, guidance, interpretations, permitting requirements, certification standards or enforcement priorities could increase our compliance costs, restrict our ability to source or distribute affected products, delay shipments, interrupt manufacturing activities or adversely affect customer demand.

If we cannot adjust our manufacturing capacity or the purchases required for our manufacturing activities to reflect changes in market conditions or customer demand, our business and financial results may suffer. In addition, our reliance upon sole or limited sources of supply for certain materials, components and services can cause production interruptions, delays and inefficiencies.

We purchase materials, components and equipment from third parties for use in many of our manufacturing operations. Our profitability could be adversely impacted if we are unable to adjust our purchases to reflect changes in customer demand and market fluctuations, including those caused by seasonality or cyclicality. During a market upturn, suppliers from time to time extend lead times, limit supplies or increase prices. If we cannot purchase sufficient products at competitive prices and quality and on a timely enough basis to meet increasing demand, we may not be able to satisfy market demand, product shipments may be delayed, our costs may increase, or we may breach our contractual commitments and incur liabilities. Conversely, in order to secure supplies for the production of products, we sometimes enter into noncancelable purchase commitments with vendors, which can impact our ability to adjust our inventory to reflect declining market demands. If demand for our products is less than we expect, we may experience additional excess and obsolete inventories and be forced to incur additional charges and our business and financial results may suffer.

In addition, some of our businesses purchase certain materials from sole or limited source suppliers for reasons of quality assurance, regulatory requirements, cost effectiveness, availability or uniqueness of design. If these or other suppliers encounter financial, operating or other difficulties or if our relationship with them changes, we might not be able to quickly establish or qualify replacement sources of supply. The supply chains for our businesses can also be disrupted by supplier capacity constraints, bankruptcy or exiting of the business for other reasons, decreased availability of key raw materials or commodities and external events such as natural disasters, pandemic health issues, war, terrorist actions, governmental actions (such as trade protectionism) and legislative or regulatory changes. Any of these factors can result in production interruptions, delays, extended lead times and inefficiencies. Because we cannot always immediately adapt our production capacity and related cost structures to changing market conditions, at times our manufacturing capacity may exceed or fall short of our production requirements. Any or all of these problems can result in the loss of customers, provide an opportunity for competing products to gain market acceptance and otherwise adversely affect our business and financial results.

The Company relies heavily on internal manufacturing and related operations to produce, package and distribute its products which, if disrupted, could materially impair our business operations. Our business could be adversely affected by disruptions at our sites.

The Company’s internal quality control, packaging and distribution operations support the majority of the Company’s sales. Since certain Company products must comply with FDA regulations and because in all instances the Company creates value for its customers through the development of high-quality products, any significant decline in quality or disruption of operations for any reason could adversely affect sales and customer relationships, and therefore adversely affect the business. While we have taken certain steps to manage these operational risks, the Company’s future sales growth and earnings may be adversely affected by perceived disruption risks or actual disruptions.

We rely upon our manufacturing operations to produce many of the products we sell and our warehouse facilities to store products, pending sale. Any significant disruption of those operations for any reason, such as strikes or other labor unrest, power interruptions, fire, hurricanes or other events beyond our control could adversely affect our sales and customer relationships and therefore adversely affect our business. We have significant operations in California, near major earthquake faults, which make us susceptible to earthquake risk. Although most of our raw materials are available from a number of potential suppliers, our operations also depend upon our ability to obtain raw materials at reasonable prices. If

21

Table of Contents

we are unable to obtain the materials we need at a reasonable price, we may not be able to produce certain of our products or we may not be able to produce certain of these products at a marketable price, which could have an adverse effect on our results of operations.

Climate change and/or related environmental risks, or legal or regulatory measures to address climate change and/or related environmental risks, may negatively affect us.

Climate change resulting from increased concentrations of carbon dioxide and other greenhouse gases in the atmosphere could present risks to our operations. For example, we have significant operations in California, where serious drought has made water less available and more costly and has increased the risk of wildfires. Changes in climate patterns leading to extreme heat waves or unusually cold weather at some of our locations can lead to increased energy usage and costs, or otherwise adversely impact our facilities and operations and disrupt our supply chains and distribution systems. Concern over climate change can also result in new or additional legal or regulatory requirements designed to reduce greenhouse gas emissions or mitigate the effects of climate change on the environment. Any such new or additional legal or regulatory requirements may increase the costs associated with, or disrupt, sourcing, manufacturing and distribution of our products, which may adversely affect our business and financial results. In addition, any failure to adequately address stakeholder expectations with respect to environmental, social and governance (“ESG”) matters may result in the loss of business, adverse reputational impacts, diluted market valuations and challenges in attracting and retaining customers and talented employees. In addition, our adoption of certain standards or mandated compliance to certain requirements could necessitate additional investments that could impact our profitability.

Defects, unanticipated use of, or inadequate disclosure with respect to our products, or allegations thereof, can adversely affect our business and financial results.

Certain of our products and services are sold for use in diagnostics. For those products and services in particular, manufacturing or design defects in, unanticipated use of, safety or quality issues (or the perception of such issues) with respect to, “off label” use of, or inadequate disclosure of risks relating to the use of products and services that we make or sell (including items that we source from third-parties) can lead to personal injury, death, and/or property damage and adversely affect our business and financial results. These events can lead to recalls or safety alerts, result in the removal of a product or service from the market and result in product liability or similar claims being brought against us. Recalls, removals and product liability and similar claims (regardless of their validity or ultimate outcome) result in significant costs, as well as negative publicity and damage to our reputation that could reduce demand for our products and services. Our business can also be affected by studies of the utilization, safety and efficacy of medical device products and components that are conducted by industry participants, government agencies and others. Any of the above can result in the discontinuation of marketing of such products in one or more countries and give rise to claims for damages from persons who believe they have been injured as a result of product issues, including claims by individuals or groups seeking to represent a class.

Because we rely heavily on third-party package-delivery services, a significant disruption in these services or significant increases in prices may disrupt our ability to ship products, increase our costs and lower our profitability.

Most of our reagent products need to be stored and shipped at certain cold temperatures. Consequently, we ship a significant portion of our products to our customers by express mail or air delivery through package delivery companies, such as FedEx in the U.S. and DHL in Europe. If one or more of these third-party package-delivery providers were to experience a major work stoppage, preventing our products from being delivered in a timely fashion or causing us to incur additional shipping costs we could not pass on to our customers, our costs could increase and our relationships with certain of our customers could be adversely affected. In addition, if one or more of these third-party package-delivery providers were to increase prices, and we were not able to find comparable alternatives or make adjustments in our delivery network, our profitability could be adversely affected.

The proposed acquisition of the Company by Merck KGaA, Darmstadt, Germany may disrupt or adversely affect our business, prospects, financial condition and results of operations.

On June 25, 2026, the Company entered into the Merger Agreement with Parent and Merger Sub. The Merger Agreement provides that, on the terms and subject to the conditions set forth therein, Merger Sub will merge with and into the Company, with the Company surviving the Merger as a wholly-owned subsidiary of Parent. At the Effective Time, each share of the Company’s common stock, other than Company Restricted Stock (as defined in the Merger Agreement), issued and outstanding immediately prior to the Effective Time, other than Excluded Shares (as defined in the Merger Agreement), will be converted into the right to receive $73.00 in cash, without interest and less any required tax withholdings. The completion of the Merger remains subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, including receipt of required regulatory approvals and approval by the Company’s shareholders.

The announcement and pendency of the Merger could cause disruptions in and create uncertainty surrounding our business, which could have an adverse effect on our business, prospects, financial condition and results of operations, regardless of whether the Merger is completed. During the period from the execution of the Merger Agreement until the earlier of the Effective Time and the termination of the Merger Agreement, we are required to use commercially reasonable efforts to conduct our operations in all material respects in the ordinary course of business and to maintain our existing relations and goodwill with governmental entities, customers, suppliers, distributors, creditors, lessors and employees. Subject to specified exceptions, the Merger Agreement also restricts us from taking certain actions without Parent’s prior written consent, which consent may not be unreasonably withheld, delayed or conditioned. These restrictions could affect our ability to execute our business strategies, pursue acquisitions or other business opportunities, make capital investments, incur indebtedness, manage our workforce and compensation arrangements, enter into or modify material contracts, respond effectively to competitive pressures and industry developments, and attain our financial and other goals, and these restrictions may impact our financial condition, results of operations and cash flows.

Employee retention and recruitment may be challenging before completion of the Merger, as employees and prospective employees may experience uncertainty regarding their future roles, responsibilities, compensation or employment with the Company following the Merger. Although we have entered into retention arrangements with each of our current executive officers, these arrangements may not be sufficient to retain such officers or other key employees through the completion of the Merger or thereafter. If, despite our retention and recruiting efforts, key employees depart or prospective key employees fail to accept employment with the Company because of issues relating to the uncertainty surrounding the Merger, anticipated organizational changes or a desire not to remain with the combined company, our business, financial condition and results of operations could be adversely affected.

The announcement and pendency of the Merger could also disrupt our business relationships. Customers, suppliers, distributors, collaborators, service providers, creditors and other business partners may experience uncertainty as to the future of such relationships and may delay or defer certain business decisions, seek alternative relationships with third parties, reduce or discontinue their business with us, or seek to alter their present business with us. Parties with whom we otherwise may have sought to establish business relationships may seek alternative relationships with third parties. The pursuit of the Merger and preparation for the potential integration of the Company with Parent may place a significant burden on management and our internal resources. The diversion of management’s attention away from our day-to-day business operations could adversely affect our business, financial condition and results of operations.

We may also become subject to shareholder litigation or other legal proceedings relating to the Merger or the other transactions contemplated by the Merger Agreement. Such litigation may name the Company, members of our Board of Directors or our officers as defendants and could seek, among other things, to enjoin or otherwise prevent or delay completion of the Merger. We cannot predict whether any such proceeding will be brought or the outcome of any such proceeding, including the amount of costs associated with defending or resolving such claims or any other liabilities that may be incurred. If a plaintiff were successful in obtaining an injunction prohibiting the parties from completing the Merger on the agreed-upon terms, such an injunction could delay completion of the Merger or prevent the Merger from being completed. Whether or not any claim is successful, transaction-related litigation could result in significant costs and divert management’s attention and resources, which could adversely affect our business, financial condition and results of operations.

We have incurred and expect to continue to incur substantial transaction-related fees and costs in connection with the Merger.

23

Table of Contents

We have incurred and expect to continue to incur significant costs, expenses and fees for professional services, such as legal, financial and accounting fees, and other transaction costs in connection with the Merger. A material portion of these expenses are payable by us whether or not the Merger is completed and may relate to activities that we would not have undertaken other than to complete the Merger. If the Merger is not completed, we will have received little or no benefit from such expenses. Further, although we have assumed that a certain amount of transaction expenses will be incurred, factors beyond our control could affect the total amount or the timing of these expenses. Many of the expenses that will be incurred, by their nature, are difficult to estimate accurately. These costs could adversely affect our business, financial condition and results of operations.

The Merger may not be completed within the expected timeframe, or at all, and a significant delay in or the failure to complete the Merger could adversely affect our business and the market price of our common stock.

The consummation of the Merger is subject to customary and other closing conditions, including:

Many of the conditions to the consummation of the Merger are not within our control or the control of Parent or Merger Sub, and we cannot predict when or if these conditions will be satisfied. There can be no assurance that our business, our relationships or our financial condition will not be adversely affected, as compared to the condition prior to the announcement of the Merger, if the Merger is not consummated within the expected timeframe or at all. Failure to complete the Merger within the expected timeframe, or at all, could adversely affect our business and the market price of our common stock in a number of ways, including the following:

24

Table of Contents

The Merger Agreement contains provisions that could discourage a potential competing acquirer of the Company or could result in a competing proposal being made at a lower price than it otherwise might have been.

We are subject to certain restrictions on our ability to solicit alternative acquisition proposals from third parties, to provide information to third parties and to enter into or continue discussions or negotiations with third parties regarding alternative acquisition proposals, subject to customary exceptions. In addition, we may be required to pay Parent a termination fee of approximately $230.5 million in specified circumstances, including if the Merger Agreement is terminated in specified circumstances following our receipt of a Competing Proposal (as defined in the Merger Agreement). These provisions could discourage a potential competing acquirer that might have an interest in acquiring all or a significant part of the Company from considering or proposing such an acquisition, including, if the Merger Agreement is terminated prior to the consummation of the Merger, after such termination of the Merger Agreement, even if it were prepared to pay a price per share higher than the price per share proposed to be paid in the Merger, or might result in a potential competing acquirer proposing to pay a lower price than it might otherwise have proposed to pay because of the added expense of the termination fee that may become payable in specified circumstances under the Merger Agreement, including, in certain circumstances, after a valid termination of the Merger Agreement in accordance with the terms thereof.

If the Merger Agreement is terminated and we decide to seek another similar transaction, we may not be able to negotiate or consummate a transaction with another party on terms comparable to, or better than, the terms of the Merger Agreement.

Intellectual Property Risks

We are dependent on maintaining our intellectual property rights. If we are unable to adequately protect our intellectual property, or if third parties infringe our intellectual property rights, we may suffer competitive injury or expend significant resources enforcing our rights.

Many of the markets we serve are technology-driven, and as a result intellectual property rights play a significant role in product development and differentiation. We own numerous patents, trademarks, copyrights, trade secrets and other intellectual property and licenses to intellectual property owned by others, which in aggregate are important to our business. The intellectual property rights that we obtain, however, are not always sufficiently broad and do not always provide us a significant competitive advantage, and patents may not be issued for pending or future patent applications owned by or licensed to us. In addition, the steps that we and our licensors have taken to maintain and protect our intellectual property do not always prevent it from being challenged, invalidated, circumvented, designed around or becoming subject to compulsory licensing. In some circumstances, enforcement is not available to us because an infringer has a dominant intellectual property position or for other business reasons. We also rely on nondisclosure and noncompetition agreements with employees, consultants and other parties to protect, in part, trade secrets and other proprietary rights. There can be no assurance that these agreements adequately protect our trade secrets and other proprietary rights and will not be breached, that we will have adequate remedies for any breach, that others will not independently develop substantially equivalent proprietary information or that third parties will not otherwise gain access to our trade secrets or other proprietary rights.

These risks are particularly pronounced in countries in which we do business that do not have levels of protection of corporate proprietary information, intellectual property, technology and other assets comparable to the U.S. We operate globally, with manufacturing operations in Canada, Switzerland, China and the UK, and approximately 48% of our revenue

25

Table of Contents

in fiscal 2026 was from outside the U.S. The laws, regulations and enforcement mechanisms in other countries may in some cases be less protective of our intellectual property rights. Our failure to obtain or maintain intellectual property rights that convey competitive advantage, adequately protect our intellectual property or detect or prevent circumvention or unauthorized use of such property and the cost of enforcing our intellectual property rights can adversely impact our business and financial results.

We may be involved in disputes to determine the scope, coverage and validity of others’ proprietary rights, or to defend against third-party claims of intellectual property infringement, any of which could be time-intensive and costly and may adversely impact our business.

Our success depends in part on our ability to operate without infringing the proprietary rights of others, and to obtain licenses where necessary or appropriate. We have obtained and continue to negotiate licenses to produce a number of products claimed to be owned by others. Since we have not conducted a patent infringement study for each of our products, it is possible that some of our products may unintentionally infringe patents of third parties.

We have been and may in the future be sued by third parties alleging that we are infringing their intellectual property rights. These lawsuits are expensive, take significant time, and divert management’s focus from other business concerns. If we are found to be infringing the intellectual property of others, we could be required to cease certain activities, alter our products or processes or pay licensing fees. This could cause unexpected costs and delays which may have a material adverse effect on us. If we are unable to obtain a required license on acceptable terms, or unable to design around any third party patent, we may be unable to sell some of our products and services, which could result in reduced revenue. In addition, if we do not prevail, a court may find damages or award other remedies in favor of the opposing party in any of these suits, which may adversely affect our earnings.

Financial and Tax Risks

We have entered into and drawn on a revolving credit facility, and we may incur additional debt in the future. The burden of this additional debt could adversely affect us, make us more vulnerable to adverse economic or industry conditions, and prevent us from funding our expansion strategy.

We currently have a Credit Agreement that provides for a revolving credit facility of $1 billion, which can be increased by an additional $400 million subject to certain conditions. Borrowings under the Credit Agreement bear interest at a variable rate. As of August 17, 2026, the Company had drawn $200 million under the Credit Agreement.

​

The terms of the Credit Agreement and the burden of the indebtedness incurred thereunder could have negative consequences for us, such as:

​

​

​

The Credit Agreement also contains negative covenants that limit our ability to engage in specified types of transactions. These covenants limit our ability to, among other things, sell, lease or transfer any properties or assets, with certain exceptions; and enter into certain merger, consolidation or other reorganization transactions, with certain exceptions.

A breach of any of these covenants could result in an event of default under our credit facility. Upon the occurrence of an event of default, the lender could elect to declare all amounts outstanding under such facility to be immediately due and payable and terminate all commitments to extend further credit. In addition, the Company would be subject to additional restrictions if an event of default exists under the Credit Agreement, such as a prohibition on the payment of cash dividends.

Our business and financial results can be adversely affected by foreign currency exchange rates, changes in our tax rates and tax liabilities and assessments (including as a result of changes in tax laws).

International markets contribute a substantial portion of our revenues, and we intend to continue expanding our presence in these regions. The exposure to fluctuations in currency exchange rates takes different forms. International revenues and costs are subject to the risk that fluctuations in exchange rates could adversely affect our reported revenues and profitability when translated into U.S. dollars for financial reporting purposes. These fluctuations could also adversely affect the demand for products and services provided by us. As a multinational corporation, our businesses occasionally invoice third-party customers in currencies other than the one in which they primarily do business (the "functional currency"). Movements in the invoiced currency relative to the functional currency could adversely impact our cash flows and our results of operations. As our international sales grow, exposure to fluctuations in currency exchange rates could have a larger effect on our financial results. In fiscal 2026, currency translation had a favorable effect of approximately $20 million on revenues due to the value of the U.S. dollar relative to other currencies in which the Company sells products and services.

As a global company, we are subject to taxation in numerous countries, states and other jurisdictions. In particular, we are affected by the impact of changes to tax laws or related authoritative interpretations in the U.S. In preparing our financial results, we record the amount of tax that is payable in each of the countries, states and other jurisdictions in which we operate. Our future effective tax rate, however, may be lower or higher than experienced in the past due to numerous factors, including a change in the mix of our profitability from country to country, changes in accounting for income taxes and recently enacted and future changes in tax laws in jurisdictions in which we operate. Any of these factors could cause us to experience an effective tax rate significantly different from previous periods or our current expectations, which could have an adverse effect on our business, results of operations and cash flows.

Dividends on our common stock could be reduced or eliminated in the future.

For many years, our Board has declared quarterly dividends. In the future, our Board may reduce or eliminate our common stock dividend in order to fund investments for growth, repurchase shares or conserve capital resources. While the Merger Agreement is in effect, we are prohibited from declaring, setting aside, making or paying any dividend or other distribution with respect to our capital stock to our shareholders, whether payable in cash, stock, property or a combination thereof, other than regular quarterly cash dividends on our common stock materially consistent with our past dividend policy (including with respect to timing and record date) in quarterly amounts not to exceed those set forth in the disclosure letter delivered by Bio-Techne in connection with the Merger Agreement and with record dates consistent with the dates on which quarterly dividends have been declared.

Legal, Regulatory, Compliance and Reputational Risks

Our business is subject to extensive regulation; failure to comply with these regulations could adversely affect our business and financial results.

As referenced in more detail above, we and our customers must comply with a wide array of federal, state, local and international regulations, in such areas as medical device, healthcare, import and export, anticorruption, and privacy. We develop, configure and market our products to meet customer needs created by those regulations. Any significant change in regulations could reduce demand for our products or increase our expenses. For example, many of our instruments are marketed to the pharmaceutical industry for use in discovering and developing drugs and diagnostic products. Changes in the U.S. FDA’s regulation of drug or medical device products, such as managing the price of certain prescription drugs or potentially increasing regulatory scrutiny of lab developed tests, could have an adverse effect on the demand for these products.

We have agreements relating to the sale of our products to government entities in the U.S. and elsewhere and, as a result, we are subject to various statutes and regulations that apply to companies doing business with the government (less than 1% of our fiscal 2026 sales were made to the U.S. federal government). The laws governing government contracts differ from the laws governing private contracts and government contracts may contain pricing terms and conditions that are not applicable to private contracts. We are also subject to investigation for compliance with the regulations governing

27

Table of Contents

government contracts. A failure to comply with these regulations could result in suspension of these contracts, criminal, civil and administrative penalties or debarment.

We are subject to various local, state, federal, foreign and transnational laws and regulations, which include the operating and security standards of the U.S. FDA, the U.S. Drug Enforcement Agency (the DEA), the U.S. Department of Health and Human Services (the DHHS), the USDA, APHIS, and other comparable agencies and, in the future, any changes to such laws and regulations could adversely affect us. In particular, we are subject to laws and regulations concerning current good manufacturing practices. Our subsidiaries may be required to register for permits and/or licenses with, and may be required to comply with the laws and regulations of, the DEA, the FDA, the DHHS, foreign agencies and/or comparable state agencies as well as certain accrediting bodies depending upon the type of operations and location of product distribution, manufacturing and sale. The manufacture, distribution and marketing of many of our products and services, including medical devices and pharma services, are subject to extensive ongoing regulation by the FDA, the DEA, and other equivalent local, state, federal and non-U.S. regulatory authorities. In addition, we are subject to inspections by these regulatory authorities. For example, the EU has adopted the In Vitro Diagnostic Regulation (the “EU IVDR”), which imposes stricter requirements for the marketing and sale of in vitro diagnostic medical devices, including in the area of clinical evaluation requirements, quality systems and post-market surveillance. Manufacturers of in vitro diagnostics medical devices that have been marketed and sold under the prior regulatory regime now have to comply with some of the new EU IVDR requirements, while the effective date of other requirements have been delayed. Complying with EU IVDR, the regulation applicable to the Company, may require material modifications to our quality management systems, additional resources in certain functions, updates to technical files and additional clinical data in some cases, among other changes. Failure by us or by our customers to comply with the requirements of the EU IVDR, or other requirements imposed by these or similar regulatory authorities, including without limitation, remediating any inspectional observations to the satisfaction of these regulatory authorities, could result in warning letters, product recalls or seizures, monetary sanctions, injunctions to halt manufacture and distribution, restrictions on our operations, civil or criminal sanctions, or withdrawal of existing or denial of pending approvals, including those relating to products or facilities. In addition, such a failure could expose us to contractual or product liability claims, contractual claims from our customers, including claims for reimbursement for lost or damaged active pharmaceutical ingredients, as well as ongoing remediation and increased compliance costs, any or all of which could be significant. We are the sole manufacturer of a number of products for many of our customers and a negative regulatory event could impact our customers’ ability to provide products to their customers.

We are also subject to a variety of federal, state, local and international laws and regulations that govern, among other things, the importation and exportation of products, the handling, transportation and manufacture of substances that could be classified as hazardous, and our business practices in the U.S. and abroad such as anti-competition laws. Any noncompliance by us with applicable laws and regulations or the failure to maintain, renew or obtain necessary permits and licenses could result in criminal, civil and administrative penalties and could have an adverse effect on our results of operations.

Significant developments or changes in U.S. laws or policies, including changes in U.S. trade policies and tariffs and the reaction of other countries thereto, can have an adverse effect on our business and financial results.

Significant developments or changes in U.S. laws and policies (including as a result of changes in party control of Congress or decisions from the U.S. Supreme Court), such as laws and policies governing foreign trade, manufacturing, and development and investment in the territories and countries where we or our customers operate, or governing the health care system and drug prices, can adversely affect our business and financial results. Developments or changes in national laws or policies to protect or promote domestic interests and/or address foreign competition, including laws and policies in areas such as trade, manufacturing, government purchasing, healthcare, intellectual property, regulatory enforcement and investment/development can have an adverse effect on our business and financial statements.

The U.S. has implemented, amended, and in some cases retracted tariffs on imports from a wide range of countries, and which has in some cases prompted retaliatory tariffs, or changes to existing tariffs, by a number of countries. Beginning in early April 2025, the U.S. implemented and/or announced tariffs on imports from a wide range of countries, and which has prompted a number of countries to impose retaliatory tariffs and/or changes to existing tariffs. Many of these tariffs and announcements underwent continued revision, with certain tariff levels increasing while others decreased. Additionally, the U.S. and a number of other countries have implemented a number of product- and industry- specific

28

Table of Contents

exclusions, though these exclusions have been subject to revision and/or announced revision as well. As of the date of this report, a number of the tariffs remain in effect, including significant tariffs between the U.S. and China. Collectively, these tariffs have increased and will continue to increase the cost to us of supplies and components we import, as well as our cost to serve certain markets, which in turn will require us to bear significant increased costs to do business, and/or implement surcharges, and/or increase the price of certain of our products. As a result of any surcharge or price increase, there may be an adverse impact on the demand for our products, as well as an adverse impact as to our ability to serve the market in certain countries. The increased cost of importing raw materials and components from certain countries may disrupt our supply chains, with related impacts to our operations. In addition, whenever we are unable to fully recover higher costs, or whenever there is a time delay between the increase in costs and our ability to recover these costs, our margins and profitability can decline. The U.S. and/or other countries may implement additional tariffs and/or other responsive or retaliatory measures, and which would exacerbate the risks and adverse effects noted above. Though the risks identified above in certain cases have already adversely impacted parts of our business, the full impact of these tariffs and other actions on the Company and on our business partners remains highly uncertain and subject to rapid change.

In addition, changes to laws or regulations pertaining to laboratory developed tests may adversely affect our business and financial results. These factors have adversely affected, and in the future could further adversely affect, our business and financial results.

Our business and financial results can be impaired by improper conduct by any of our employees, agents or business partners.

We cannot provide assurance that our internal controls and compliance systems, including our Code of Ethics and Business Conduct, protect us from unauthorized acts committed by employees, agents or business partners of ours (or of businesses we acquire or partner with) that violate U.S. and/or non-U.S. laws, including the laws governing payments to government officials, bribery, fraud, kickbacks and false claims, pricing, sales and marketing practices, conflicts of interest, competition, employment practices and workplace behavior, export and import compliance, economic and trade sanctions, money laundering and data privacy. In particular, the U.S. Foreign Corrupt Practices Act, the UK Bribery Act and similar anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments to government officials for the purpose of obtaining or retaining business, and we operate in many parts of the world that have experienced governmental corruption to some degree. Any such improper actions or allegations of such acts could damage our reputation and subject us to civil or criminal investigations in the U.S. and in other jurisdictions and related shareholder lawsuits, could lead to substantial civil and criminal, monetary and non-monetary penalties and could cause us to incur significant legal and investigatory fees. In addition, the government may seek to hold us liable for violations committed by companies in which we invest or that we acquire. We also rely on our suppliers to adhere to our supplier code of conduct, and material violations of such code of conduct could occur that could have a material effect on our business and financial results.

Certain of our businesses are subject to extensive regulation by the U.S. FDA and by comparable agencies of other countries, as well as laws regulating fraud and abuse in the healthcare industry and the privacy and security of health information. Failure to comply with those regulations could adversely affect our business and financial results.

Certain of our products are medical devices, diagnostics tests and other products that are subject to regulation by the U.S. FDA or state CLIA regulations, by other federal and state governmental agencies, by comparable agencies of other countries and regions and by regulations governing hazardous materials and drugs-of abuse, or the manufacture and sale of products containing any such materials. The global regulatory environment has become increasingly stringent and unpredictable. Several countries that did not have regulatory requirements for medical devices have established such requirements in recent years, and other countries have expanded, or plan to expand, their existing regulations, including implementation of IVDR regulations in Europe. Failure to meet these requirements may adversely impact our business and financial results in the applicable geographies.

Government authorities may conclude that our business practices do not comply with current or future statutes, regulations, agency guidance or case law. Failure to obtain required regulatory clearances before marketing our products (or before implementing modifications to or promoting additional indications or uses of our products), other violations of laws or regulations, failure to remediate inspectional observations to the satisfaction of these regulatory authorities, real or

29

Table of Contents

perceived efficacy or safety concerns or trends of adverse events with respect to our products (even after obtaining clearance for distribution) and unfavorable or inconsistent clinical data from existing or future clinical trials can lead to FDA Form 483 Inspectional Observations, warning letters, notices to customers, declining sales, loss of customers, loss of market share, remediation and increased compliance costs, recalls, seizures of adulterated or misbranded products, fines, expenses, injunctions, civil penalties, criminal penalties, consent decrees, administrative detentions, refusals to permit importations, partial or total shutdown of production facilities or the implementation of operating restrictions, narrowing of permitted uses for a product, refusal of the government to grant 510(k) clearance, suspension or withdrawal of approvals, pre-market notification rescissions and other adverse effects. Further, defending against any such actions can be costly and time-consuming and may require significant personnel resources. Therefore, even if we are successful in defending against any such actions brought against us, our business may be impaired. Ensuring that our internal operations and business arrangements with third parties comply with applicable laws and regulations also involves substantial costs.

Failure to comply with privacy and security laws and regulations could result in fines, penalties and damage to the Company’s reputation and have a material adverse effect upon the Company’s business, a risk that has been elevated with recent acquisitions that use protected health information and utilize healthcare providers for laboratory testing services.

If the Company does not comply with existing or new laws and regulations related to protecting the privacy and security of personal or health information, it could be subject to monetary fines, civil penalties and/or criminal sanctions. In the U.S., the Health Insurance Portability and Accountability Act of 1996 (HIPAA) privacy and security regulations, including the expanded requirements under U.S. Health Information Technology for Economic and Clinical Health Act (HITECH), establish comprehensive standards with respect to the use and disclosure of protected health information (PHI) by covered entities, in addition to setting standards to protect the confidentiality, integrity and security of PHI. HIPAA restricts the Company’s ability to use or disclose PHI, without patient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policy purposes and other permitted purposes outlined in the privacy regulations. If the laboratory operations use or disclose PHI improperly under these privacy regulations, they may incur significant fines and other penalties for wrongful use or disclosure of PHI in violation of the privacy and security regulations, including potential civil and criminal fines and penalties.

ITEM 5. MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED SHAREHOLDER

MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

The Company’s common stock is listed on the NASDAQ stock exchange under the symbol “TECH”.

Holders of Common Stock and Dividends Paid

As of August 11, 2026, there were over 210,000 beneficial shareholders of the Company’s common stock and over 110 shareholders of record. The Company paid annual cash dividends totaling $49.9 million, $50.4 million, and $50.4 million in fiscal 2026, 2025, and 2024, respectively. The Board of Directors periodically considers the payment of cash dividends, and there is no guarantee that the Company will pay comparable cash dividends, or any cash dividends, in the future.

On August 31, 2022, the Company entered into an amended and restated Credit Agreement (“Credit Agreement”) that provides for a revolving credit facility of $1 billion, which can be increased by an additional $400 million subject to certain conditions. The credit facility is governed by a Credit Agreement dated August 31, 2022 and matures on August 31, 2027. The Credit Agreement that governs the revolving line of credit contains customary events of default and would prohibit payment of dividends to Company shareholders in the event of a default thereunder.

Issuer Purchases of Equity Securities

The Company’s repurchase plan approved by the Board on February 2, 2022, granted management the discretion to mitigate the dilutive effect of stock option exercises. The plan authorized the Company to purchase up to $400 million of

the Company’s outstanding common stock. Additionally, the Board approved a new share repurchase plan on April 30, 2025, to replace the previous share repurchase plan, that authorizes the Company to purchase up to $500 million of the Company’s outstanding common stock. The table below sets forth certain information regarding our purchases of common stock in open market transactions during fiscal 2026. While the Merger Agreement is in effect, we are prohibited from repurchasing shares of our common stock, including under the February 2, 2022 and April 30, 2025 share repurchase programs, without the prior written consent of Parent.

PENDING MERGER WITH MERCK KGAA, DARMSTADT, GERMANY

On June 25, 2026, the Company entered into the Agreement and Plan of Merger (the “Merger Agreement”), with Merck KGaA, Darmstadt, Germany, a German corporation with general partners (“Parent”), and EMD Holdings NewCo, Inc., a Minnesota corporation and a wholly-owned subsidiary of Parent (“Merger Sub”). The Merger Agreement provides that, on the terms and subject to the conditions of the Merger Agreement, Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving as a wholly-owned subsidiary of Parent.

At the effective time of the Merger (the “Effective Time”), each share of the Company’s common stock, par value $0.01 per share, (each, a “Share”) (other than Company Restricted Stock (as defined in the Merger Agreement)) issued and outstanding immediately prior to the Effective Time (other than Excluded Shares (as defined in the Merger Agreement)) will automatically be converted into the right to receive $73.00 in cash (the “Merger Consideration”), without any interest thereon and less any required tax withholdings and all of such Shares will cease to be outstanding and cease to exist.

If the Merger Agreement is terminated under certain specified circumstances, we or Parent will be required to pay a termination fee to the other party. The Company will be required to pay Parent a termination fee of approximately $230.5 million under specified circumstances, including termination of the Merger Agreement in connection with our entry into an agreement with respect to a Superior Proposal (as defined in the Merger Agreement) at any time prior to us receiving shareholder approval of the Merger Agreement, or termination by Parent if the Company’s Board of Directors effects a Change of Company Recommendation (as defined in the Merger Agreement). Parent will be required to pay the Company a termination fee of approximately $576.1 million under specified circumstances, including termination of the Merger Agreement due to the failure to consummate the Merger by the Outside Date (as defined in the Merger Agreement) as a

OVERALL RESULTS

Operational Update

For fiscal 2026, consolidated net sales remained flat at $1.2 billion as compared to fiscal 2025. Organic revenue remained flat from the prior year. Foreign currency translation had a favorable impact of 2% and a business held-for-sale had an unfavorable impact of 2%.

​

Consolidated net earnings for fiscal 2026 increased 148% compared to fiscal 2025. The increase in earnings was favorably impacted by a non-recurring impairment charge in the prior year, a non-recurring arbitration award in the prior year, and a recovery of assets held-for-sale. After adjusting for cost recognized upon sale of acquired inventory, intangibles amortization, acquisition-related costs, certain litigation charges, investment loss and other non-operating loss, stock-based compensation, restructuring and restructuring-related costs, impairment (recovery) of assets held-for-sale, and impact of businesses held-for-sale, adjusted net earnings decreased 1% in fiscal 2026 as compared to fiscal 2025. Adjusted net earnings was primarily impacted by unfavorable product mix and pricing pressures.

For fiscal 2025, consolidated net sales increased 5% as compared to fiscal 2024. Organic growth was 5% and foreign currency translation and a business held-for-sale did not have a material impact. Organic revenue growth was primarily driven by strong commercial execution in our Protein Sciences segment.

​

Consolidated net earnings for fiscal 2025 decreased 56% compared to fiscal 2024. The decrease in earnings was impacted by a non-recurring loss on an arbitration award, impairment of assets held-for-sale, and restructuring and restructuring-related charges. After adjusting for cost recognized upon sale of acquired inventory, intangibles amortization, acquisition-related costs, certain litigation charges, gain on sale of investments, stock-based compensation, restructuring and restructuring-related costs, impairment of assets held-for-sale, and impact of business held-for-sale, adjusted net earnings increased 8% in fiscal 2025 as compared to fiscal 2024. Adjusted net earnings was primarily impacted by favorable volume leverage within Protein Sciences.
