Fair Value Measurements
ASC Topic 820, Fair Value Measurement (“Topic 820”) established a framework for measuring fair value. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The three levels of the fair value hierarchy under Topic 820 are described below:
Level 1: Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access.
Level 2: Inputs to the valuation methodology are quoted market prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.
Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement.
The fair value measurement level for assets and liabilities within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.
Assets and Liabilities Measured at Fair Value on a Recurring Basis
The following table summarizes the Company’s assets and liabilities measured at fair value on a recurring basis within each level of the fair value hierarchy:

Money Market Funds
The Company has investments in money market funds, which are included in cash and cash equivalents and fiduciary cash on the consolidated balance sheets. Fair value inputs for these investments are considered Level 1 measurements within the fair value hierarchy since money market fund fair values are known and observable through daily published floating values.
Derivative Instruments
Derivative instruments include an interest rate swap and interest rate caps. The fair value of the interest rate swap at December 31, 2025 was determined using an income approach based on the terms of the interest rate swap and inputs corroborated by observable market data, including interest rate curves. The fair value of interest rate caps at December 31, 2024 was determined using the market standard methodology of discounting the future expected cash receipts that would occur if variable interest rates rise above the strike rate of the caps. The variable interest rates used in the calculation of projected receipts on the caps are based on an expectation of future interest rates derived from observable market interest rate curves and volatilities. Derivative instruments are classified within Level 2 of the fair value hierarchy.
Contingent Earnout Liabilities
Methodologies used for liabilities measured at fair value on a recurring basis within Level 3 of the fair value hierarchy are based on limited unobservable inputs. These methods may produce a fair value calculation that may not be indicative of the net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.
The fair value of contingent earnout liabilities is based on sales projections for the acquired entities, which are reassessed each reporting period. Based on the Company’s ongoing assessment of the fair value of its contingent earnout liabilities, the Company recorded a net increase (decrease) in the estimated fair value of such liabilities of $5.6 million, $(4.9) million and $61.1 million for the years ended December 31, 2025, 2024 and 2023, respectively. The Company has assessed the maximum estimated exposure to the contingent earnout liabilities to be $50.0 million at December 31, 2025.
The Company measures contingent earnout liabilities at fair value each reporting period using significant unobservable inputs classified within Level 3 of the fair value hierarchy. The Company uses a probability weighted value analysis as a valuation technique to convert future estimated cash flows to a single present value amount. The significant unobservable inputs used in the fair value measurements are sales projections over the earnout period, and the probability outcome percentages assigned to each scenario. Significant increases or decreases to either of these inputs would result in a significantly higher or lower liability with a higher liability capped by the contractual maximum of the contingent earnout liabilities. Ultimately, the liability will be equivalent to the amount settled, and the difference between the fair value estimate and amount settled will be recorded in earnings for business combinations, or as a change in the cost of the assets acquired for asset acquisitions.
The fair value of the contingent earnout liabilities is based on the present value of the expected future payments to be made to partners in accordance with the provisions outlined in the respective purchase agreements, which at times includes Monte Carlo simulations or a discounted cash flow analysis. In determining fair value, the Company estimates the partner’s future performance using financial projections developed by management for the partner and market participant assumptions that were derived for revenue growth, EBITDA growth and retention rates. Revenue or EBITDA growth rates for earnouts with ongoing measurement periods were generally 20% at December 31, 2025 and from 20% to 25% at December 31, 2024. The Company estimates future payments using the earnout formula and performance targets specified in each purchase agreement and these financial projections. These payments are generally discounted to present value using a risk-adjusted rate that takes into consideration market-based rates of return that reflect the ability of the partner to achieve the targets. However, no significant discount rates have been applied to the remaining material contingent earnout liabilities at December 31, 2025 or 2024 due, in part, to the short-term nature of a substantial portion of the liabilities wherein their fair values approximate their carrying values. Changes in financial projections, market participant assumptions for revenue growth, or the risk-adjusted discount rate, would result in a change in the fair value of contingent consideration.
The following table sets forth a summary of the changes in the fair value of the Company’s contingent earnout liabilities, which are measured at fair value on a recurring basis utilizing Level 3 assumptions in their valuation:

__________
(1) The Company reclassified $(1.8) million and $41.9 million of its contingent earnout liabilities through the issuance (reduction) of colleague earnout incentives during the years ended December 31, 2025 and 2024, respectively, which results in a reclassification between the change in fair value of contingent consideration and colleague compensation and benefits expense in the consolidated statements of comprehensive loss.
(2) The Company settled $5.6 million of its contingent earnout liabilities through the issuance of related party notes payable during the year ended December 31, 2024. The consolidated statements of cash flows for the years ended December 31, 2025 and 2024 include $5.6 million and $1.5 million, respectively, of payments of contingent earnout consideration related to similar non-cash settlements in prior periods.
Fair Value of Assets and Liabilities Not Measured at Fair Value
The fair value of long-term debt and the revolving line of credit is based on an estimate using a discounted cash flow analysis and current borrowing rates for similar types of borrowing arrangements. The carrying amount and estimated fair value of long-term debt and the revolving line of credit were as follows:
