Fair Value Measurement
ASC 820, Fair Value Measurements and Disclosures, requires that the Company disclose estimated fair values for its financial instruments. The estimated fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in the principal or most advantageous market for the asset or liability. Fair value estimates are made at a specific point in time and are based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial instrument. Changes in assumptions could significantly affect these estimates. Because the fair value is estimated as of December 31, 2025 and 2024, the amounts that will actually be realized or paid at settlement or maturity of the instruments in the future could be significantly different.
The estimated fair values of the Company's financial instruments represent management's best estimates of the amounts that would be received to sell those assets or that would be paid to transfer those liabilities in an orderly transaction between market participants at that date. The estimated fair value measurements maximize the use of observable inputs. However, in situations where there is little, if any, market activity for the asset or liability at the measurement date, the estimated fair value measurement reflects management's own judgments about the assumptions that market participants would use in pricing the asset or liability. These judgments are developed by the Company based on the best information available under the circumstances.
The following summary presents a description of the methods and assumptions used to estimate the fair value of each class of financial instrument.
Equity Method Investments — The estimated fair value of the Company's equity method investments are privately negotiated investments. The carrying amount of these investments approximates the fair value.
Pension Plan Assets — The estimated fair value of ACT's pension plan assets are based on quoted prices in active markets that are readily and regularly obtainable.
Debt Instruments and Leases — For notes payable under the 2025 Revolver, the 2025 Term Loans, the 2023 Term Loan, the 2021 Revolver, the 2021 Term Loans, the 2021 Prudential Notes, and the revenue equipment installment notes, fair value approximates the carrying value due to the variable interest rate. The carrying value of the 2023 RSA approximates fair value, as the underlying receivables are short-term in nature and only eligible receivables (such as those with high credit ratings) are qualified to secure the borrowed amounts. For finance and operating lease liabilities, the carrying value approximates the fair value, as the Company's finance and operating lease liabilities are structured to amortize in a manner similar to the depreciation of the underlying assets.
Contingent Consideration — The estimated fair value of the Company's contingent consideration owed to sellers is calculated using applicable models and inputs for each acquired entity.
Other — Cash and cash equivalents, restricted cash, net accounts receivable, income tax refund receivable, and accounts payable represent financial instruments for which the carrying amount approximates fair value, as they are short-term in nature. These instruments are accordingly excluded from the disclosures below. All remaining balance sheet amounts excluded from the below are not considered financial instruments, subject to this disclosure.
Fair Value Hierarchy — ASC 820 establishes a framework for measuring fair value in accordance with GAAP and expands financial statement disclosure requirements for fair value measurements. ASC 820 further specifies a hierarchy of valuation techniques, which is based on whether the inputs into the valuation technique are observable or unobservable. The hierarchy follows:
•Level 1 — Valuation techniques in which all significant inputs are quoted prices from active markets for assets or liabilities that are identical to the assets or liabilities being measured.
•Level 2 — Valuation techniques in which significant inputs include quoted prices from active markets for assets or liabilities that are similar to the assets or liabilities being measured and/or quoted prices from markets that are not active for assets or liabilities that are identical or similar to the assets or liabilities being measured. Also, model-derived valuations in which all significant inputs and significant value drivers are observable in active markets are Level 2 valuation techniques.
•Level 3 — Valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are valuation technique inputs that reflect the Company's own assumptions about the assumptions that market participants would use in pricing an asset or liability.

1The Company measures contingent consideration 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 forecasted operating income and net income 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.
The following is a rollforward for the summary of changes in the fair value of the Company's contingent consideration liabilities, which are measured at fair value on a recurring basis utilizing Level 3 assumptions:

(a)The fair values of the mandatorily redeemable contingent consideration and other contingent consideration related to the U.S. Xpress Acquisition are based on Monte Carlo simulations that measure the present value of the expected future payments to be made in accordance with the provisions outlined in the purchase agreement, which is a Level 3 fair value measurement. In determining fair value, the Company estimates the future performance using financial projections developed by management about operating income and net income and the volatility associated with operating income and net income. As of December 31, 2025, the Company used volatility rates of 31.0% and 42.0% for operating income and net income, respectively. The Company estimates future payments using the earnout formula and performance targets specified in the purchase agreement and these financial projections. These payments are discounted to present value using a risk-adjusted rate that takes into consideration market-based rates of return that reflect the ability of U.S. Xpress to achieve the targets. As of December 31, 2025 the Company used a discount rate of 5.4%. Changes in financial projections or the risk-adjusted discount rate, would result in a change in the fair value of contingent consideration. As of December 31, 2024, the Company used volatility rates of 38.0% and 41.0% for operating income and net income, respectively and a discount rate of 5.7%.
Based on the Company’s ongoing assessment of the fair value of the contingent consideration, no adjustment was recorded to the estimated fair value of such liabilities during 2025. During 2024, the Company recorded a net decrease in the estimated fair value of such liabilities of $36.6 million. These were recognized as a gain and are recorded in "Other income (expense), net" in the Company's consolidated statement of comprehensive income.

Fair Value of Pension Plan Assets — The following table sets forth the level within the fair value hierarchy of ACT's pension plan financial assets accounted for at fair value on a recurring basis. Assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. ACT's assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of these assets and their placement within the fair value hierarchy levels.
