Fair Value Measurements
The Company believes that the carrying amounts of its financial instruments, including cash and cash equivalents, trade accounts receivable and accounts payable, consist primarily of instruments without extended maturities, which approximate fair value primarily due to their short-term maturities and low risk of counterparty default. The Company considers all highly liquid investments purchased with a maturity of 90 days or less on the date of purchase to be cash equivalents. Cash equivalents as of December 31, 2024 consisted of overnight repurchase agreements in which cash from the Company's main operating checking account is invested overnight in highly liquid, short term investments and certain investments in money market funds sponsored by a large financial institution. Cash equivalents as of December 31, 2023 consisted of overnight repurchase agreements, short term investments, one U.S. Treasury Bill and certain investments in money market funds. For the years ended December 31, 2024 and 2023, the Company recognized interest income in the aggregate of approximately $2.2 million and $1.2 million, respectively. The Company did not recognize interest income during the year ended December 31, 2022. The Company has not experienced any losses in its cash and cash equivalents and management believes the Company is not exposed to significant credit risk with respect to such accounts.

Earnout Payments
As a part of the total consideration for the Jake Marshall Transaction, the former owners of JMLLC and CSLLC were eligible to receive up to an aggregate of $6.0 million in cash, consisting of two tranches of $3.0 million, as defined in the purchase agreement, if the gross profit of the acquired companies equals or exceeds $10.0 million in (i) the approximately 12-month period from closing through December 31, 2022 (the “2022 Jake Marshall Earnout Period”) or (ii) fiscal year 2023 (the “2023 Jake Marshall Earnout Period”), respectively (collectively, the “Jake Marshall Earnout Payments”). To the extent, however, that the gross profit of the acquired companies was less than $10.0 million, but exceeds $8.0 million, during any of the 2022 Jake Marshall Earnout Period or 2023 Jake Marshall Earnout Period, the $3.0 million amount was to be prorated for such period. The Company initially recognized $3.1 million in contingent consideration, of which the entire balance was included in other long-term liabilities in the Company’s consolidated balance sheets on December 2, 2021. The fair value of contingent Jake Marshall Earnout Payments is based on generating growth rates on the projected gross margins of the acquired entities and calculating the associated contingent payments based on achieving the earnout targets, which are reassessed each reporting period. In April 2023 and 2024, the Company made two separate payments in the amount of $3.0 million to the former owners of JMLLC and CSLLC related to the 2022 Jake Marshall Earnout Period and the 2023 Jake Marshall Earnout Period, respectively.
As a part of the total consideration for the ACME Transaction, the Company recognized $1.5 million in contingent consideration on the ACME Effective Date.

Interest Rate Swap
The fair value of the interest rate swap is determined using widely accepted valuation techniques and reflects the contractual terms of the interest rate swap including the period to maturity, and while there are no quoted prices in active markets, it uses observable market-based inputs, including interest rate curves and implied volatilities. The fair value analysis also considers a
credit valuation adjustment to reflect nonperformance risk of both the Company and the single counterparty. The fair value of the interest rate contract has been determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. The interest rate swap is classified as a Level 2 item within the fair value hierarchy. As of December 31, 2024, the Company determined that the fair value of the interest rate swap was approximately $0.2 million and is recognized in other assets on the Company's consolidated balance sheets. For the years ended December 31, 2024, 2023 and 2022, the Company recognized gain of less than $0.1 million, a loss of $0.1 million and a gain of $0.3 million, respectively, on its consolidated statements of operations associated with the change in fair value of the interest rate swap arrangement.
