Jun. 30, 2025
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation In our opinion, the accompanying unaudited interim consolidated financial statements include all adjustments, consisting of normal recurring adjustments, which are necessary to fairly state our financial position, results of operations and cash flows. The interim consolidated results of operations are not necessarily indicative of the results that may occur for the full fiscal year. Certain footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been omitted pursuant to instructions, rules and regulations prescribed by the SEC. The disclosures provided herein should be read in conjunction with the audited financial statements and notes thereto included in our 2024 Form 10-K.
Accounting Estimates and Assumptions	Accounting Estimates and Assumptions The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions affecting the reported amounts of assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses for the reporting period. Those estimates are inherently subject to change and actual results could differ from those estimates. In the accompanying unaudited interim consolidated financial statements, estimates are used for, but not limited to, the valuation of assets (including intangibles assets, goodwill and long-lived assets), liabilities, consideration related to business combinations and asset acquisitions, revenue recognition (including variable consideration), estimated selling prices for performance obligations in contracts with multiple performance obligations, reserves for claims and performance-based arrangements, credit losses, depreciable lives of assets, impairment of long-lived assets, stock-based compensation, deferred income taxes and valuation allowance, contingent liabilities, purchase price allocation in taxable stock transactions and useful lives of intangible assets.
Principles of Consolidation	Principles of Consolidation The unaudited interim consolidated financial statements include the accounts of Evolent Health, Inc. and its subsidiaries. All intercompany accounts and transactions are eliminated in consolidation.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all highly liquid instruments with original maturities of three months or less to be cash equivalents. The Company holds materially all of our cash in bank deposits with the Federal Deposit Insurance Corporation (“FDIC”) participating banks at cost which approximates fair value.
Business Combinations	Business Combinations Companies acquired during each reporting period are reflected in the results of the Company effective from their respective dates of acquisition through the end of the reporting period. The Company allocates the fair value of purchase consideration to the assets acquired and liabilities assumed based on their estimated fair values at the acquisition date. Our estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. Critical estimates used to value certain identifiable assets include, but are not limited to, expected long-term revenues, future expected operating expenses, cost of capital and appropriate discount rates. The excess of the fair value of purchase consideration over the fair value of the assets acquired and liabilities assumed in the acquired entity is recorded as goodwill. If the Company obtains new information about facts and circumstances that existed as of the acquisition date during the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded on the Company’s consolidated statements of operations and comprehensive income (loss). For contingent consideration recorded as a liability, the Company initially measures the amount at fair value as of the acquisition date and adjusts the liability to fair value at each reporting period. Changes in the fair value of contingent consideration, other than measurement period adjustments, are recognized in operating expenses on the consolidated statements of operations and comprehensive income (loss). Transaction-related expenses are recognized separately from the business combination and are expensed as incurred.
Goodwill	Goodwill We recognize the excess of the purchase price, plus the fair value of any non-controlling interests in the acquiree, over the fair value of identifiable net assets acquired as goodwill. Goodwill is not amortized, but is reviewed at least annually for indications of impairment, with consideration given to financial performance and other relevant factors. We perform impairment tests of goodwill at a reporting unit level on October 31 of each year. We perform impairment tests between annual tests if an event occurs, or circumstances change, that we believe would more likely than not reduce the fair value of a reporting unit below its carrying amount. Our goodwill impairment analysis first assesses qualitative factors to determine whether events or circumstances existed that would lead the Company to conclude it is more likely than not that the fair value of its reporting unit is below its carrying amount. If the Company determines that it is more likely than not that the fair value of its reporting unit is below the carrying amount, a quantitative goodwill assessment is required. In the quantitative evaluation, the fair value of our reporting unit is determined and compared to the carrying value. If the fair value is greater than the carrying value, then the carrying value is deemed to be recoverable and no further action is required. If the fair value estimate is less than the carrying value, goodwill is considered impaired for the amount by which the carrying amount exceeds our reporting unit’s fair value and a charge is reported in goodwill impairment on our consolidated statements of operations and comprehensive income (loss).
Intangible Assets, Net	Intangible Assets, Net Identified intangible assets are recorded at their estimated fair values at the date of acquisition and are amortized over their respective estimated useful lives using a method of amortization that reflects the pattern in which the economic benefits of the intangible assets are used. As part of the organizational changes as a result of growth in our value-based specialty care business, we sunset several corporate trade names and replaced them with Evolent signifying our adoption and launch of a unified brand. As a result, we accelerated amortization such that all corporate trade names were fully amortized by December 2024. Intangible assets are reviewed for impairment if circumstances indicate the Company may not be able to recover the asset’s carrying value. The Company evaluates recoverability by determining whether the undiscounted cash flows expected to result from the use and eventual disposition of that asset or group exceed the carrying value at the evaluation date. If the undiscounted cash flows are not sufficient to cover the carrying value, the Company measures an impairment loss as the excess of the carrying amount of the long-lived asset or group over its fair value.
Research and Development Costs	Research and Development Costs Research and development costs consist primarily of personnel and related expenses (including stock-based compensation and employee taxes and benefits) for employees engaged in research and development activities as well as third-party fees. All such costs are expensed as incurred. We focus our research and development efforts on activities that support our technology infrastructure, clinical program development, data analytics and network development capabilities. Research and development costs are recorded within selling, general and administrative expenses on our consolidated statements of operations and comprehensive income (loss).
Reserves for Claims and Performance-based Arrangements	Reserves for Claims and Performance-based Arrangements Reserves for claims and performance-based arrangements reflect estimates of payments under performance-based arrangements and the ultimate cost of claims that have been incurred but not reported, including expected development on reported claims, those that have been reported but not yet paid (reported claims in process) and other medical care expenses and services payable that are primarily composed of accruals for incentives and other amounts payable to health care professionals and facilities. The Company uses actuarial principles and assumptions that are consistently applied in each reporting period and recognizes the actuarial best estimate of the ultimate liability along with a margin for adverse deviation. This approach is consistent with actuarial standards of practice that the liabilities be adequate under moderately adverse conditions. The process of estimating reserves involves a considerable degree of judgment by the Company and, as of any given date, is inherently uncertain. The methods for making such estimates and for establishing the resulting liability are continually reviewed and adjustments are reflected in current results of operations in the period in which they are identified as experience develops or new information becomes known.
Right of Offset	Right of Offset Certain customer arrangements give the Company the legal right to net payment for amounts due from customers and claims payable. As of June 30, 2025 and December 31, 2024, approximately 79% and 67%, respectively, of gross accounts receivable has been netted against claims payable in lieu of cash receipt. Furthermore, as of June 30, 2025 and December 31, 2024, approximately 56% and 23% of our accounts receivable, net could ultimately be settled on a net basis, once the criteria for netting have been met. The increase is primarily due to another customer becoming eligible to settle balances on a net basis. Additionally, the Company offsets its accounts receivable and claims reserve under its total cost of care management solution.
Debt	Debt Convertible notes and amounts borrowed under our Credit Agreements are carried at cost, net of debt discounts and issuance costs, as long-term debt or short-term debt on the consolidated balance sheets based on remaining time to maturity. The debt discounts and issuance costs are amortized to interest expense on the consolidated statements of operations and comprehensive income (loss) using the effective interest rate method. Cash interest payments are due either quarterly or semi-annually in arrears and we accrue interest expense monthly based on the applicable rate.
Leases	Leases The Company enters into various office space, data center and equipment lease agreements in conducting its normal business operations. At the inception of any contract, the Company evaluates the agreement to determine whether the contract contains a lease. If the contract contains a lease, the Company then evaluates the term and whether the lease is an operating or finance lease. Most leases include one or more options to renew or may have a termination option. The Company determines whether these options are reasonably certain to be exercised at the inception of the lease. The rent expense is recognized on a straight-line basis in the consolidated statements of operations and comprehensive income (loss) over the terms of the respective leases. Leases with an initial term of 12 months or less are not recorded on the consolidated balance sheets. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. Further, the Company treats all lease and non-lease components as a single combined lease component for all classes of underlying assets. The Company also enters into sublease agreements for some of its leased office space. Rental income attributable to subleases is immaterial and is offset against rent expense over the terms of the respective leases. The Company reviews long-lived assets, which include operating lease right-of-use asset assets, for impairment when facts or circumstances indicate the carrying amount of an asset or asset group may not be recoverable. If impairment indicators are present and the estimated future undiscounted cash flows are less than the carrying value of the assets, the carrying values are reduced to the estimated fair value. Fair values are determined based on quoted market values, discounted cash flows and external market data, as applicable.
Revenue Recognition	Revenue Recognition Our revenue contracts are typically multi-year arrangements with customers to provide solutions designed to lower the medical expenses of our partners and include our total cost of care management and specialty care management services solutions, provide comprehensive health plan operations and claims processing services, and also include transition or run-out services to customers. We use the following 5-step model, outlined in Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC 606”), to determine revenue recognition from our contracts with customers: • Identify the contract(s) with a customer • Identify the performance obligations in the contract • Determine the transaction price • Allocate the transaction price to performance obligations • Recognize revenue when (or as) the entity satisfies a performance obligation Our revenue contracts are typically multi-year arrangements with customers to provide solutions designed to lower the medical expenses of our partners and include our total cost of care management and specialty care management services solutions, provide comprehensive health plan operations and claims processing services, and also include transition or run-out services to customers. Our performance obligation in these arrangements is to provide an integrated suite of services, including access to our platform that is customized to meet the specialized needs of our partners and providers. Generally, we will apply the series guidance to the performance obligation as we have determined that each time increment is distinct. We primarily utilize a variable fee structure for these services that typically includes a monthly payment that is calculated based on a specified per member per month rate, multiplied by the number of members that our partners are managing under a value-based care arrangement or a percentage of plan premiums. Our arrangements may also include other variable fees related to service level agreements, shared medical savings arrangements and other performance measures. Variable consideration is estimated using the most likely amount based on our historical experience and best judgment at the time. Due to the nature of our arrangements, certain estimates may be constrained if it is probable that a significant reversal of revenue will occur when the uncertainty is resolved. We recognize revenue over time using the time elapsed output method. Fixed consideration is recognized ratably over the contract term. In accordance with the series guidance, we allocate variable consideration to the period to which the fees relate. Our revenue includes certain services which are billed on a per-case basis. Contracts with Multiple Performance Obligations Our contracts with customers may contain multiple performance obligations, primarily when the partner has requested both administrative services and other services such as our specialty care management or total cost of care management services as these services are distinct from one another. When a contract has multiple performance obligations, we allocate the transaction price to each performance obligation based on the relative standalone selling price using the expected cost margin approach. This approach requires estimates regarding both the level of effort it will take to satisfy the performance obligation as well as fees that will be received under the variable pricing model. We also take into consideration customer demographics, current market conditions, the scope of services and our overall pricing strategy and objectives when determining the standalone selling price. Principal vs. Agent We use third parties to assist in satisfying our performance obligations. In order to determine whether we are the principal or agent in the arrangement, we review each third-party relationship on a contract-by-contract basis. As we integrate goods and services provided by third parties into our overall service, we control the services provided to the customer prior to its delivery. As such, we are the principal and we will recognize revenue on a gross basis. In certain cases, we do not control the services from third parties before it is delivered to the customer, thereby recognizing revenue on a net basis.
Convertible Preferred Equity	Convertible Preferred Equity Our shares of Convertible Preferred Equity are classified within temporary equity, as events outside the Company’s control triggers such shares to become redeemable. Costs associated with the issuance of redeemable preferred stock are presented as discounts to the carrying value of the redeemable preferred stock and are amortized using the effective interest method, over the term of the Convertible Preferred Equity.
Recently Issued Accounting Standards	Recently Issued Accounting Standards In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”), which enhances the disclosures required for operating segments in the Company’s annual and interim consolidated financial statements, including those companies with a single operating segment. ASU 2023-07 is effective retrospectively for fiscal years beginning after December 15, 2023 and for interim periods within fiscal years beginning after December 15, 2024. The Company adopted ASU 2023-07 for the year ended December 31, 2024. See Note 20 for segment disclosures. In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 includes requirements that an entity disclose specific categories in the rate reconciliation and provide additional information for reconciling items that are greater than five percent of the amount computed by multiplying pretax income (or loss) by the applicable statutory income tax rate. The standard also requires that entities disclose income (or loss) from continuing operations before income tax expense (or benefit) and income tax expense (or benefit) each disaggregated between domestic and foreign. The Company adopted ASU 2023-09 effective January 1, 2025. We do not expect this standard to have a material impact to our results of operations, cash flows or financial condition. In November 2024, the FASB issued ASU 2024-03, “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses” (“ASU 2024-03”). ASU 2024-03 requires additional disclosure of specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted. ASU 2024-03 may be applied prospectively with the option for retrospective application for all prior periods presented. The Company is currently evaluating the impact of adopting this guidance on the Company’s current financial position, results of operations or financial statement disclosures. In November 2024, the FASB issued ASU 2024-04, Debt with Conversion and Other Options (Subtopic 470-20) “Induced Conversions of Convertible Debt Instruments” to clarify the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion. Under the amendments, to account for a settlement of a convertible debt instrument as an induced conversion, an inducement offer is required to provide the debt holder with, at a minimum, the consideration (in form and amount) issuable under the conversion privileges provided in the terms of the instrument. An entity should assess whether this criterion is satisfied as of the date the inducement offer is accepted by the holder. If, when applying this criterion, the convertible debt instrument had been exchanged or modified (without being deemed substantially different) within the one-year period leading up to the offer acceptance date, an entity should compare the terms provided in the inducement offer with the terms that existed one year before the offer acceptance date. The amendments in this update also clarify that the induced conversion guidance applies to a convertible debt instrument that is not currently convertible as long as it had a substantive conversion feature as of both its issuance date and the date the inducement offer is accepted. The amendments are effective for all entities for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. The Company is examining the impact this pronouncement may have on the Company’s consolidated financial statements. In May 2025, the FASB issued ASU 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810) “Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity” to improve the requirements for identifying the accounting acquirer in Topic 805, Business combinations. It is a revision of the current guidance for determining the accounting acquirer for a transaction affected primarily by exchanging equity interest in which the legal acquiree is a variable interest entity (VIE) that meets the definition of a business. The amendment in this update requires an entity involved in an acquisition transaction to consider additional factors in ASC 805 to determine which entity is the accounting acquirer thus improving comparability between business combinations and consequently focusing at enhancing financial statements. In a business combination, the accounting acquiree’s assets and liabilities are generally required to be initially measured at fair value, subject to specific exceptions in Topic 805 and the accounting acquirer’s existing assets and liabilities are not remeasured under the business combinations guidance. ASU 2025-03 expands the factors to consider when determining the accounting acquirer and acquiree as it can significantly affect the carrying amounts of the combined entity’s assets and liabilities thus affecting post combination net income. This amendment is different than current GAAP because for certain transactions, they replace the requirement that the primary beneficiary always is the acquirer by inducing the reporting entity to use an assessment to examine the factors in ASC 805-10-55-12 through 55-15 to determine which entity is the accounting acquirer. Application of this revision is prospectively to any acquisition transaction that occurs after the initial application date. The amendments are effective for all entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods. The Company is examining the impact this pronouncement may have on the Company’s consolidated financial statements. In May 2025, the FASB issued ASU 2025-04, Compensation—Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606) “Clarifications to Share-Based Consideration Payable to a Customer” to provide context in share-based considerations payable to a customer. The update reduces diversity in practice and improves the decision usefulness of the guidance for share-based consideration payable to a customer in conjunction with selling goods or services. Amendments in Accounting Standards Update No. 2019-08, Compensation—Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606) require that if share-based consideration payable to a customer contains vesting conditions, the grantor must determine whether the vesting conditions represent service conditions or performance conditions. That determination can affect when the grantor recognizes revenue because it is required to estimate the probable outcome of a performance condition and also consider forfeitures. For instance, when the grantor elects to account for forfeitures as they occur, revenue recognition may be delayed for awards that are not probable of vesting. ASU 2025-04 revises the definition of a “performance condition” and eliminates a forfeiture policy election for service conditions associated with share-based consideration payable to a customer. The amendments in this Update permit a grantor to apply the new guidance on either a modified retrospective or a retrospective basis. The amendments in this Update are effective for all entities for annual reporting periods (including interim reporting periods within annual reporting periods) beginning after December 15, 2026. Early adoption is permitted for all entities. The Company is examining the impact this pronouncement may have on the Company’s consolidated financial statements.
Fair Value Measurement	Fair Value Measurement GAAP defines fair value as the price that would be received from the sale of an asset or paid to transfer a liability (an exit price) assuming an orderly transaction in the most advantageous market at the measurement date. GAAP also establishes a hierarchical disclosure framework which prioritizes and ranks the level of observability of inputs used in measuring fair value. These tiers include: •Level 1 - inputs to the valuation methodology are quoted prices available in active markets for identical instruments as of the reporting date; •Level 2 - inputs to the valuation methodology are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date and the fair value can be determined through the use of models or other valuation methodologies; and •Level 3 - inputs to the valuation methodology are unobservable inputs in situations where there is little or no market activity for the asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the particular asset or liability being measured. These items are recorded in accrued liabilities on our consolidated balance sheets. Nonrecurring Fair Value Measurements In addition to the assets and liabilities that are recorded at fair value on a recurring basis, the Company records certain assets and liabilities at fair value on a nonrecurring basis as required by GAAP. Generally, assets are recorded at fair value on a nonrecurring basis as a result of impairment charges. This includes assets and liabilities recorded in business combinations or asset acquisitions, goodwill, intangible assets, property, plant and equipment and equity method investments. While not carried at fair value on a recurring basis, these items are continually monitored for indicators of impairment that would indicate current carrying value is greater than fair value. In those situations, the assets are considered impaired and written down to current fair value. Other Fair Value Disclosures The carrying amounts of cash and cash equivalents (those not held in a money market fund), restricted cash and receivables approximate their fair values because of the relatively short-term maturities of these items and financial instruments.

Basis of Presentation, Summary of Significant Accounting Policies and Change in Accounting Principles (Policies)

6 Months Ended

Jun. 30, 2025

In our opinion, the accompanying unaudited interim consolidated financial statements include all adjustments, consisting of normal recurring adjustments, which are necessary to fairly state our financial position, results of operations and cash flows. The interim consolidated results of operations are not necessarily indicative of the results that may occur for the full fiscal year. Certain footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been omitted pursuant to instructions, rules and regulations prescribed by the SEC. The disclosures provided herein should be read in conjunction with the audited financial statements and notes thereto included in our 2024 Form 10-K.

Accounting Estimates and Assumptions

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions affecting the reported amounts of assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses for the reporting period. Those estimates are inherently subject to change and actual results could differ from those estimates. In the accompanying unaudited interim consolidated financial statements, estimates are used for, but not limited to, the valuation of assets (including intangibles assets, goodwill and long-lived assets), liabilities, consideration related to business combinations and asset acquisitions, revenue recognition (including variable consideration), estimated selling prices for performance obligations in contracts with multiple performance obligations, reserves for claims and performance-based arrangements, credit losses, depreciable lives of assets, impairment of long-lived assets, stock-based compensation, deferred income taxes and valuation allowance, contingent liabilities, purchase price allocation in taxable stock transactions and useful lives of intangible assets.

Principles of Consolidation

The unaudited interim consolidated financial statements include the accounts of Evolent Health, Inc. and its subsidiaries. All intercompany accounts and transactions are eliminated in consolidation.

Cash and Cash Equivalents

We consider all highly liquid instruments with original maturities of three months or less to be cash equivalents. The Company holds materially all of our cash in bank deposits with the Federal Deposit Insurance Corporation (“FDIC”) participating banks at cost which approximates fair value.

Business Combinations

Companies acquired during each reporting period are reflected in the results of the Company effective from their respective dates of acquisition through the end of the reporting period. The Company allocates the fair value of purchase consideration to the assets acquired and liabilities assumed based on their estimated fair values at the acquisition date. Our estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. Critical estimates used to value certain identifiable assets include, but are not limited to, expected long-term revenues, future expected operating expenses, cost of capital and appropriate discount rates.

The excess of the fair value of purchase consideration over the fair value of the assets acquired and liabilities assumed in the acquired entity is recorded as goodwill. If the Company obtains new information about facts and circumstances that existed as of the acquisition date during the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded on the Company’s consolidated statements of operations and comprehensive income (loss).

For contingent consideration recorded as a liability, the Company initially measures the amount at fair value as of the acquisition date and adjusts the liability to fair value at each reporting period. Changes in the fair value of contingent consideration, other than measurement period adjustments, are recognized in operating expenses on the consolidated statements of operations and comprehensive income (loss). Transaction-related expenses are recognized separately from the business combination and are expensed as incurred.

Goodwill

We recognize the excess of the purchase price, plus the fair value of any non-controlling interests in the acquiree, over the fair value of identifiable net assets acquired as goodwill. Goodwill is not amortized, but is reviewed at least annually for indications of impairment, with consideration given to financial performance and other relevant factors. We perform impairment tests of goodwill at a reporting unit level on October 31 of each year. We perform impairment tests between annual tests if an event occurs, or circumstances change, that we believe would more likely than not reduce the fair value of a reporting unit below its carrying amount.

Our goodwill impairment analysis first assesses qualitative factors to determine whether events or circumstances existed that would lead the Company to conclude it is more likely than not that the fair value of its reporting unit is below its carrying amount. If the Company determines that it is more likely than not that the fair value of its reporting unit is below the carrying amount, a quantitative goodwill assessment is required. In the quantitative evaluation, the fair value of our reporting unit is determined and compared to the carrying value. If the fair value is greater than the carrying value, then the carrying value is deemed to be recoverable and no further action is required. If the fair value estimate is less than the carrying value, goodwill is considered impaired for the amount by which the carrying amount exceeds our reporting unit’s fair value and a charge is reported in goodwill impairment on our consolidated statements of operations and comprehensive income (loss).

Intangible Assets, Net

Identified intangible assets are recorded at their estimated fair values at the date of acquisition and are amortized over their respective estimated useful lives using a method of amortization that reflects the pattern in which the economic benefits of the intangible assets are used.

As part of the organizational changes as a result of growth in our value-based specialty care business, we sunset several corporate trade names and replaced them with Evolent signifying our adoption and launch of a unified brand. As a result, we accelerated amortization such that all corporate trade names were fully amortized by December 2024.

Intangible assets are reviewed for impairment if circumstances indicate the Company may not be able to recover the asset’s carrying value. The Company evaluates recoverability by determining whether the undiscounted cash flows expected to result from the use and eventual disposition of that asset or group exceed the carrying value at the evaluation date. If the undiscounted cash flows are not sufficient to cover the carrying value, the Company measures an impairment loss as the excess of the carrying amount of the long-lived asset or group over its fair value.

Research and Development Costs

Research and development costs consist primarily of personnel and related expenses (including stock-based compensation and employee taxes and benefits) for employees engaged in research and development activities as well as third-party fees. All such costs are expensed as incurred. We focus our research and development efforts on activities that support our technology infrastructure, clinical program development, data analytics and network development capabilities. Research and development costs are recorded within selling, general and administrative expenses on our consolidated statements of operations and comprehensive income (loss).

Reserves for Claims and Performance-based Arrangements

Reserves for claims and performance-based arrangements reflect estimates of payments under performance-based arrangements and the ultimate cost of claims that have been incurred but not reported, including expected development on reported claims, those that have been reported but not yet paid (reported claims in process) and other medical care expenses and services payable that are

primarily composed of accruals for incentives and other amounts payable to health care professionals and facilities. The Company uses actuarial principles and assumptions that are consistently applied in each reporting period and recognizes the actuarial best estimate of the ultimate liability along with a margin for adverse deviation. This approach is consistent with actuarial standards of practice that the liabilities be adequate under moderately adverse conditions.

The process of estimating reserves involves a considerable degree of judgment by the Company and, as of any given date, is inherently uncertain. The methods for making such estimates and for establishing the resulting liability are continually reviewed and adjustments are reflected in current results of operations in the period in which they are identified as experience develops or new information becomes known.

Right of Offset

Certain customer arrangements give the Company the legal right to net payment for amounts due from customers and claims payable. As of June 30, 2025 and December 31, 2024, approximately 79% and 67%, respectively, of gross accounts receivable has been netted against claims payable in lieu of cash receipt. Furthermore, as of June 30, 2025 and December 31, 2024, approximately 56% and 23% of our accounts receivable, net could ultimately be settled on a net basis, once the criteria for netting have been met. The increase is primarily due to another customer becoming eligible to settle balances on a net basis. Additionally, the Company offsets its accounts receivable and claims reserve under its total cost of care management solution.

Debt

Convertible notes and amounts borrowed under our Credit Agreements are carried at cost, net of debt discounts and issuance costs, as long-term debt or short-term debt on the consolidated balance sheets based on remaining time to maturity. The debt discounts and issuance costs are amortized to interest expense on the consolidated statements of operations and comprehensive income (loss) using the effective interest rate method. Cash interest payments are due either quarterly or semi-annually in arrears and we accrue interest expense monthly based on the applicable rate.

Leases

The Company enters into various office space, data center and equipment lease agreements in conducting its normal business operations. At the inception of any contract, the Company evaluates the agreement to determine whether the contract contains a lease. If the contract contains a lease, the Company then evaluates the term and whether the lease is an operating or finance lease. Most leases include one or more options to renew or may have a termination option. The Company determines whether these options are reasonably certain to be exercised at the inception of the lease. The rent expense is recognized on a straight-line basis in the consolidated statements of operations and comprehensive income (loss) over the terms of the respective leases. Leases with an initial term of 12 months or less are not recorded on the consolidated balance sheets.

As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. Further, the Company treats all lease and non-lease components as a single combined lease component for all classes of underlying assets.

The Company also enters into sublease agreements for some of its leased office space. Rental income attributable to subleases is immaterial and is offset against rent expense over the terms of the respective leases.

The Company reviews long-lived assets, which include operating lease right-of-use asset assets, for impairment when facts or circumstances indicate the carrying amount of an asset or asset group may not be recoverable. If impairment indicators are present and the estimated future undiscounted cash flows are less than the carrying value of the assets, the carrying values are reduced to the estimated fair value. Fair values are determined based on quoted market values, discounted cash flows and external market data, as applicable.

Revenue Recognition

Our revenue contracts are typically multi-year arrangements with customers to provide solutions designed to lower the medical expenses of our partners and include our total cost of care management and specialty care management services solutions, provide comprehensive health plan operations and claims processing services, and also include transition or run-out services to customers.

We use the following 5-step model, outlined in Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC 606”), to determine revenue recognition from our contracts with customers:

• Identify the contract(s) with a customer

• Identify the performance obligations in the contract

• Determine the transaction price

• Allocate the transaction price to performance obligations

• Recognize revenue when (or as) the entity satisfies a performance obligation

Our performance obligation in these arrangements is to provide an integrated suite of services, including access to our platform that is customized to meet the specialized needs of our partners and providers. Generally, we will apply the series guidance to the performance obligation as we have determined that each time increment is distinct. We primarily utilize a variable fee structure for these services that typically includes a monthly payment that is calculated based on a specified per member per month rate, multiplied by the number of members that our partners are managing under a value-based care arrangement or a percentage of plan premiums. Our arrangements may also include other variable fees related to service level agreements, shared medical savings arrangements and other performance measures. Variable consideration is estimated using the most likely amount based on our historical experience and best judgment at the time. Due to the nature of our arrangements, certain estimates may be constrained if it is probable that a significant reversal of revenue will occur when the uncertainty is resolved. We recognize revenue over time using the time elapsed

output method. Fixed consideration is recognized ratably over the contract term. In accordance with the series guidance, we allocate variable consideration to the period to which the fees relate. Our revenue includes certain services which are billed on a per-case basis.

Contracts with Multiple Performance Obligations

Our contracts with customers may contain multiple performance obligations, primarily when the partner has requested both administrative services and other services such as our specialty care management or total cost of care management services as these services are distinct from one another. When a contract has multiple performance obligations, we allocate the transaction price to each performance obligation based on the relative standalone selling price using the expected cost margin approach. This approach requires estimates regarding both the level of effort it will take to satisfy the performance obligation as well as fees that will be received under the variable pricing model. We also take into consideration customer demographics, current market conditions, the scope of services and our overall pricing strategy and objectives when determining the standalone selling price.

Principal vs. Agent

We use third parties to assist in satisfying our performance obligations. In order to determine whether we are the principal or agent in the arrangement, we review each third-party relationship on a contract-by-contract basis. As we integrate goods and services provided by third parties into our overall service, we control the services provided to the customer prior to its delivery. As such, we are the principal and we will recognize revenue on a gross basis. In certain cases, we do not control the services from third parties before it is delivered to the customer, thereby recognizing revenue on a net basis.

Convertible Preferred Equity

Our shares of Convertible Preferred Equity are classified within temporary equity, as events outside the Company’s control triggers such shares to become redeemable. Costs associated with the issuance of redeemable preferred stock are presented as discounts to the carrying value of the redeemable preferred stock and are amortized using the effective interest method, over the term of the Convertible Preferred Equity.

Recently Issued Accounting Standards

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”), which enhances the disclosures required for operating segments in the Company’s annual and interim consolidated financial statements, including those companies with a single operating segment. ASU 2023-07 is effective retrospectively for fiscal years beginning after December 15, 2023 and for interim periods within fiscal years beginning after December 15, 2024. The Company adopted ASU 2023-07 for the year ended December 31, 2024. See Note 20 for segment disclosures.

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 includes requirements that an entity disclose specific categories in the rate reconciliation and provide additional information for reconciling items that are greater than five percent of the amount computed by multiplying pretax income (or loss) by the applicable statutory income tax rate. The standard also requires that entities disclose income (or loss) from continuing operations before income tax expense (or benefit) and income tax expense (or benefit) each disaggregated between domestic and foreign. The Company adopted ASU 2023-09 effective January 1, 2025. We do not expect this standard to have a material impact to our results of operations, cash flows or financial condition.

In November 2024, the FASB issued ASU 2024-03, “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses” (“ASU 2024-03”). ASU 2024-03 requires additional disclosure of specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted. ASU 2024-03 may be applied prospectively with the option for retrospective application for all prior periods presented. The Company is currently evaluating the impact of adopting this guidance on the Company’s current financial position, results of operations or financial statement disclosures.

In November 2024, the FASB issued ASU 2024-04, Debt with Conversion and Other Options (Subtopic 470-20) “Induced Conversions of Convertible Debt Instruments” to clarify the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion. Under the amendments, to account for a settlement of a convertible debt instrument as an induced conversion, an inducement offer is required to provide the debt holder with, at a minimum, the consideration (in form and amount) issuable under the conversion privileges provided in the terms of the instrument. An entity should assess whether this criterion is satisfied as of the date the inducement offer is accepted by the holder. If, when applying this criterion, the convertible debt instrument had been exchanged or modified (without being deemed substantially different) within the one-year period leading up to the offer acceptance date, an entity should compare the terms provided in the inducement offer with the terms that existed one year before the offer acceptance date. The amendments in this update also clarify that the induced conversion guidance applies to a convertible debt instrument that is not currently convertible as long as it had a substantive conversion feature as of both its issuance date and the date the inducement offer is accepted. The amendments are effective for all entities for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. The Company is examining the impact this pronouncement may have on the Company’s consolidated financial statements.

In May 2025, the FASB issued ASU 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810) “Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity” to improve the requirements for identifying the accounting acquirer in Topic 805, Business combinations. It is a revision of the current guidance for determining the accounting acquirer for a

transaction affected primarily by exchanging equity interest in which the legal acquiree is a variable interest entity (VIE) that meets the definition of a business. The amendment in this update requires an entity involved in an acquisition transaction to consider additional factors in ASC 805 to determine which entity is the accounting acquirer thus improving comparability between business combinations and consequently focusing at enhancing financial statements. In a business combination, the accounting acquiree’s assets and liabilities are generally required to be initially measured at fair value, subject to specific exceptions in Topic 805 and the accounting acquirer’s existing assets and liabilities are not remeasured under the business combinations guidance. ASU 2025-03 expands the factors to consider when determining the accounting acquirer and acquiree as it can significantly affect the carrying amounts of the combined entity’s assets and liabilities thus affecting post combination net income. This amendment is different than current GAAP because for certain transactions, they replace the requirement that the primary beneficiary always is the acquirer by inducing the reporting entity to use an assessment to examine the factors in ASC 805-10-55-12 through 55-15 to determine which entity is the accounting acquirer. Application of this revision is prospectively to any acquisition transaction that occurs after the initial application date. The amendments are effective for all entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods. The Company is examining the impact this pronouncement may have on the Company’s consolidated financial statements.

In May 2025, the FASB issued ASU 2025-04, Compensation—Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606) “Clarifications to Share-Based Consideration Payable to a Customer” to provide context in share-based considerations payable to a customer. The update reduces diversity in practice and improves the decision usefulness of the guidance for share-based consideration payable to a customer in conjunction with selling goods or services. Amendments in Accounting Standards Update No. 2019-08, Compensation—Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606) require that if share-based consideration payable to a customer contains vesting conditions, the grantor must determine whether the vesting conditions represent service conditions or performance conditions. That determination can affect when the grantor recognizes revenue because it is required to estimate the probable outcome of a performance condition and also consider forfeitures. For instance, when the grantor elects to account for forfeitures as they occur, revenue recognition may be delayed for awards that are not probable of vesting. ASU 2025-04 revises the definition of a “performance condition” and eliminates a forfeiture policy election for service conditions associated with share-based consideration payable to a customer. The amendments in this Update permit a grantor to apply the new guidance on either a modified retrospective or a retrospective basis. The amendments in this Update are effective for all entities for annual reporting periods (including interim reporting periods within annual reporting periods) beginning after December 15, 2026. Early adoption is permitted for all entities. The Company is examining the impact this pronouncement may have on the Company’s consolidated financial statements.

Fair Value Measurement

GAAP defines fair value as the price that would be received from the sale of an asset or paid to transfer a liability (an exit price) assuming an orderly transaction in the most advantageous market at the measurement date. GAAP also establishes a hierarchical disclosure framework which prioritizes and ranks the level of observability of inputs used in measuring fair value. These tiers include:

•Level 1 - inputs to the valuation methodology are quoted prices available in active markets for identical instruments as of the reporting date;

•Level 2 - inputs to the valuation methodology are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date and the fair value can be determined through the use of models or other valuation methodologies; and

•Level 3 - inputs to the valuation methodology are unobservable inputs in situations where there is little or no market activity for the asset or liability.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Our assessment of

the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the particular asset or liability being measured. These items are recorded in accrued liabilities on our consolidated balance sheets.

Nonrecurring Fair Value Measurements

In addition to the assets and liabilities that are recorded at fair value on a recurring basis, the Company records certain assets and liabilities at fair value on a nonrecurring basis as required by GAAP. Generally, assets are recorded at fair value on a nonrecurring basis as a result of impairment charges. This includes assets and liabilities recorded in business combinations or asset acquisitions, goodwill, intangible assets, property, plant and equipment and equity method investments. While not carried at fair value on a recurring basis, these items are continually monitored for indicators of impairment that would indicate current carrying value is greater than fair value. In those situations, the assets are considered impaired and written down to current fair value.

Other Fair Value Disclosures

The carrying amounts of cash and cash equivalents (those not held in a money market fund), restricted cash and receivables approximate their fair values because of the relatively short-term maturities of these items and financial instruments.
