Basic income per share excludes dilution and is computed by dividing earnings available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted income per share reflects the dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in our earnings. Income per share is the same for both Class A and Class B shares.

The following table sets forth, for the periods indicated, the calculation of net income per share included in the condensed consolidated statements of operations:

There were no unvested shares or unvested options excluded from the calculation of diluted earnings per share as the effect of any assumed exercise of the related awards would have been anti-dilutive for the three months ended March 31, 2025 and 2024.

Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Accordingly, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or liability.

The fair value of our interest rate swap agreements is determined using the market-standard methodology of netting the discounted future fixed-cash payments and the discounted expected variable-cash receipts. The variable-cash receipts are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. These analyses reflect the contractual terms of the swap, including the period to maturity, and use observable market-based inputs, including interest rate curves and implied volatilities. The fair value calculation also includes an amount for risk of non-performance of our counterparties using "significant unobservable inputs" such as estimates of current credit spreads to evaluate the likelihood of default, which we have determined to be insignificant to the overall fair value of our interest rate swap agreements.

The fair value of the contingent consideration arrangement is based on inputs that are not observable in the market and is estimated using a probability-weighted method. The significant unobservable inputs used in the fair value of the contingent consideration liability include the financial projections over the earn-out period, the volatility of the underlying financial metrics, and estimated discount rates.

The fair value of the life insurance policies was determined by the underwriting insurance company’s valuation models and represents the guaranteed value we would receive upon surrender of these policies as of the reporting date.

A three-tier fair value hierarchy is used to prioritize the inputs in measuring fair value as follows:

Financial Instruments Measured at Fair Value on a Recurring Basis

The carrying amount of cash and cash equivalents, certificates of deposit, accounts receivable, accounts payable, and current debt approximates their fair value because of the short-term maturity of these instruments. 

Interest rates that are currently available to us for issuance of long-term debt with similar terms and remaining maturities are used to estimate the fair value of our long-term debt, which primarily consists of revenue equipment installment notes. The fair value of our revenue equipment installment notes approximated the carrying value as of  March 31, 2025, as the weighted average interest rate on these notes approximates the market rate for similar debt. Borrowings under our revolving Credit Facility (as defined herein) approximate fair value due to the variable interest rate on that facility.

Contingent consideration arrangements require us to pay up to $20.0 million of additional consideration to AAT Carriers, Inc.'s ("AAT's") former shareholders based on AAT's results during the first two post-acquisition years, of which the final installment was made during 2024, up to $30.0 million of additional consideration to Lew Thompson & Son Trucking, Inc.'s ("LTST's") former shareholders based on LTST's results during the first three calendar years following closing, up to $12.0 million of additional consideration to Sims Transport Services, LLC's ("Sims") former shareholders based on Sims' results during the first four calendar years following closing, and up to $5.0 million of additional consideration to the seller of the assets of a small, multi-stop distribution carrier we acquired in February 2025 (the "Asset Acquisition").

The fair value of the contingent consideration is adjusted at each reporting period based on changes to the expected cash flows and related assumptions. There were contingent consideration payments made during the three months ended March 31, 2025 and 2024 of $12.5 million based on LTST's results for the first calendar year following closing and $10.0 million based on AAT's results for the second post-acquisition year, respectively. Of the $12.5 million paid for the contingent consideration liability during 2025, $4.5 million was classified as financing cash flows and $8.0 million was classified as operating cash flows within the condensed consolidated statements of cash flows. Of the $10.0 million paid for the contingent consideration liability during 2024, $7.0 million was classified as financing cash flows and $3.0 million was classified as operating cash flows within the condensed consolidated statements of cash flows. The fair value of the contingent consideration increased $0.7 million and $8.1 million related to a change in the fair value for the LTST contingent consideration for the three months ended March 31, 2025 and 2024, respectively. Additionally, contingent consideration increased $5.0 million for the three months ended March 31, 2025 as a result of the Asset Acquisition. The adjustment to the fair value of the contingent consideration liability was recorded as a component of general supplies and expenses within the condensed consolidated statements of operations. The contingent consideration liability is included in accounts payable and other long-term liabilities in our condensed consolidated balance sheets. 

The following table provides a summary (in thousands) of the activity for the contingent consideration liability for 2025:

We have four reportable segments:

The Company's chief operating decision maker ("CODM"), the Chief Executive Officer, evaluates the operating results through reportable segment operating income, which includes certain corporate overhead allocations directly attributable to each of the segments. We do not report our intersegment revenues by segment to our CODM and do not believe they are a meaningful metric for evaluating the performance of our reportable segments.

Each segment uses certain shared infrastructure and each segment is presented with its direct costs and an allocation of shared overhead costs. Insurance and claims expense is charged to the segments based on their historic claims experience and an allocation of current insurance premiums.

The CODM uses operating income for each segment in the annual budget and strategic planning process. The CODM considers budget-to-actual variances on a quarterly basis as well as month-over-month variances when making decisions about the allocation of operating and capital resources to each segment. The CODM also uses segment operating income for evaluating pricing strategy, to assess the performance of each segment by comparing the results of each segment with one another, and in determining the compensation of certain employees.

The following table summarizes our total revenue by our four reportable segments, as used by our CODM in making decisions regarding allocation of resources etc., for the three months ended March 31, 2025 and 2024:

Balance sheet data by reportable segment is not maintained by the Company.

Income tax expense in both 2025 and 2024 varies from the amount computed by applying the federal corporate income tax rates of 21% to income before income taxes, primarily due to state income taxes, net of federal income tax effect, adjusted for permanent differences the most significant of which is the effect of the per diem pay structure for drivers, executive compensation disallowance, and excess tax benefits on share-based compensation. Drivers who meet the requirements to receive per diem receive non-taxable per-diem pay in lieu of a portion of their taxable wages. This per diem program increases our drivers' net pay per mile, after taxes, while decreasing gross pay, before taxes. As a result, salaries, wages, and related expenses are slightly lower and our effective income tax rate is higher than the statutory rate. Generally, as pre-tax income increases, the impact of the driver per diem program on our effective tax rate decreases, because aggregate per diem pay becomes smaller in relation to pre-tax income, while in periods where earnings are at or near breakeven the impact of the per diem program on our effective tax rate is significant. Due to the partially nondeductible effect of per diem pay, our tax rate will fluctuate in future periods based on fluctuations in earnings.

Our liability recorded for uncertain tax positions as of  March 31, 2025 is unchanged since  December 31, 2024.

The net deferred tax liability of $114.4 million primarily relates to differences in cumulative book versus tax depreciation of property and equipment, partially off-set by net operating loss carryovers and insurance claims that have been reserved but not paid. The carrying value of our deferred tax assets assumes that we will be able to generate, based on certain estimates and assumptions, sufficient future taxable income in certain tax jurisdictions to utilize these deferred tax benefits. If these estimates and related assumptions change in the future, we may be required to establish a valuation allowance against the carrying value of the deferred tax assets, which would result in additional income tax expense. On a periodic basis, we assess the need for adjustment of the valuation allowance. The Company has determined that a valuation allowance was not necessary at March 31, 2025 for its deferred tax assets since it is more likely than not they will be realized from the future reversals of temporary differences. If these estimates and related assumptions change in the future, we may be required to modify our valuation allowance against the carrying value of the deferred tax assets.

The American Rescue Plan extended the reach of IRC Section 162(m) to include compensation paid to the eight highest-paid individuals other than the chief executive officer and the chief financial officers (rather than the three highest), however, this change is not effective until 2027. There is no material impact to the financial statements at this time.

We do not anticipate the Inflation Reduction Act (the "IRA") will have a significant impact on income tax expense or on other taxes. One of the most impactful provisions of the IRA includes the establishment of a Corporate Alternative Minimum Tax ("CAMT"). However, this tax only applies to corporations with three-year average earnings in excess of $1.0 billion. We will continue to monitor the CAMT each year to determine if we will become an applicable corporation. Additionally, the IRA enacted an excise tax on stock buybacks, which imposes a 1% tax on stock buybacks, subject to netting provisions regarding stock awarded to employees as part of their compensation. We do not believe this will have a material impact on our active repurchase program.

Current and long-term debt and lease obligations consisted of the following as of  March 31, 2025 and December 31, 2024:

We and substantially all of our subsidiaries are parties to the Third Amended and Restated Credit Agreement (the "Credit Facility") with Bank of America, N.A., as agent (the "Agent") and JPMorgan Chase Bank, N.A. (together with the Agent, the "Lenders"). The Credit Facility is a $110.0 million revolving credit facility, with an uncommitted accordion feature that, so long as no event of default exists, allows us to request an increase in the revolving credit facility of up to $75.0 million subject to Lender acceptance of the additional funding commitment. The Credit Facility includes a letter of credit sub facility in an aggregate amount of $105.0 million and a swing line sub facility in an aggregate amount equal to the greater of $10.0 million or 10% of the Lenders' aggregate commitments under the Credit Facility from time-to-time. The Credit Facility matures in May 2027.

Borrowings under the Credit Facility are classified as either "base rate loans" or "SOFR loans." Base rate loans accrue interest at a base rate equal to the greater of the Agent’s prime rate, the federal funds rate plus 0.5%, or SOFR for a one month period as of such day, plus an applicable margin ranging from 0.25% to 0.75%; while SOFR loans accrued interest at SOFR, plus an applicable margin ranging from 1.25% to 1.75%. The applicable rates are adjusted quarterly based on average pricing availability. The unused line fee is the product of 0.25% times the average daily amount by which the Lenders' aggregate revolving commitments under the Credit Facility exceed the outstanding principal amount of revolver loans and the aggregate undrawn amount of all outstanding letters of credit issued under the Credit Facility. The obligations under the Credit Facility are guaranteed by us and secured by a pledge of substantially all of our assets, with the notable exclusion of any real estate, revenue equipment pledged under other financing agreements, including revenue equipment installment notes and finance leases, and revenue equipment that we do not designate as being included in the borrowing base.

Borrowings under the Credit Facility are subject to a borrowing base limited to the lesser of (A) $110.0 million, minus the sum of the stated amount of all outstanding letters of credit; or (B) the sum of (i) 87.5% of eligible accounts receivable, plus (ii) the least of (a) 85% of the appraised net orderly liquidation value of eligible revenue equipment, (b) 100% of the net book value of eligible revenue equipment, (c) 60.0% of the Lenders' aggregate revolving commitments under the Credit Facility, or (d) $65.0 million. 

We had no borrowings outstanding under the Credit Facility as of March 31, 2025, undrawn letters of credit outstanding of approximately $19.9 million, and available borrowing capacity of $90.1 million. As of March 31, 2025, there were no base rate and no SOFR loans. Based on availability as of March 31, 2025 and 2024, there was no fixed charge coverage requirement.

The Credit Facility includes usual and customary events of default for a facility of this nature and provides that, upon the occurrence and continuation of an event of default, payment of all amounts payable under the Credit Facility may be accelerated, and the Lenders' commitments may be terminated. If an event of default occurs under the Credit Facility and the Lenders cause, or have the ability to cause, all of the outstanding debt obligations under the Credit Facility to become due and payable, this could result in a default under other debt instruments that contain acceleration or cross-default provisions. The Credit Facility contains certain restrictions and covenants relating to, among other things, debt, dividends, liens, acquisitions and dispositions outside of the ordinary course of business, and affiliate transactions. Failure to comply with the covenants and restrictions set forth in the Credit Facility could result in an event of default. 

Pricing for the revenue equipment installment notes is quoted by the respective financial affiliates of our primary revenue equipment suppliers and other lenders at the funding of each group of equipment acquired and include fixed annual rates for new equipment under retail installment contracts. The notes included in the funding are due in monthly installments with final maturities at various dates ranging from  February 2028 to March 2031. The notes contain certain requirements regarding payment, insuring of collateral, and other matters, but do not have any financial or other material covenants or events of default except certain notes totaling $28.3 million are cross-defaulted with the Credit Facility. Additional borrowings from the financial affiliates of our primary revenue equipment suppliers and other lenders are expected to be available to fund new tractors expected to be delivered in 2025, while any other property and equipment purchases, including trailers, are expected to be funded with a combination of available cash, notes, operating leases, finance leases, and/or from the Credit Facility.

In August 2015, we financed a portion of the purchase of our corporate headquarters, a maintenance facility, and certain surrounding property in Chattanooga, Tennessee by entering into a $28.0 million variable rate note with a third-party lender. The note contains certain restrictions and covenants that are usual and customary for a note of this nature. Failure to comply with the covenants and restrictions set forth in the note could result in an event of default. Concurrently with entering into the note, we entered into an interest rate swap to effectively fix the related interest rate to 4.2%. We expect to be in compliance with our debt covenants for the next 12 months. 

In connection with the settlement of a dispute related to the sale of Transport Financial Services (the "TFS Settlement"), in September 2020, TBK Bank, SSB, as lender and agent for Triumph (“TBK Bank”), provided the Company with a $45 million line of credit (the “Draw Note”), the proceeds of which are to be used solely to satisfy our indemnification obligations under the TFS Settlement. We may borrow pursuant to the Draw Note until September 23, 2025.

The finance leases in effect at  March 31, 2025 terminate from  May 2025 through  November 2033 and contain guarantees of the residual value of the related equipment by us.

 A summary of our lease obligations at March 31, 2025 and 2024 are as follows:

As of  March 31, 2025, and December 31, 2024, right-of-use assets of $39.7 million and $40.0 million for operating leases and $3.5 million and $4.6 million for finance leases, respectively, are included in net property and equipment in our condensed consolidated balance sheets. Operating lease right-of-use asset amortization is included in revenue equipment rentals and purchased transportation and general supplies and expenses, depending on the underlying asset, in the condensed consolidated statement of operations. Amortization of finance leased assets is included in depreciation and amortization expense in the condensed consolidated statement of operations.

Our future minimum lease payments as of March 31, 2025, are summarized as follows by lease category:

⁽¹⁾ Excludes the three months ended March 31, 2025.

Our Third Amended and Restated 2006 Omnibus Incentive Plan, as amended (the "Incentive Plan") governs the issuance of equity awards and other incentive compensation to management and members of the Board of Directors (the "Board"). The Incentive Plan includes (i) a fungible share reserve feature, under which shares subject to stock options and stock appreciation rights will be counted as one share for every share granted and shares subject to all other awards will be counted as 1.80 shares for every share granted, (ii) a double-trigger vesting requirement upon a change in control, and (iii) a maximum award granted or payable to any one participant under the Incentive Plan for a calendar year of 1,000,000 shares of Class A common stock or $4,000,000, in the event the award is paid in cash.

The Incentive Plan permits annual awards of shares of our Class A common stock to executives, other key employees, consultants, non-employee directors, and eligible participants under various types of options, restricted stock, or other equity instruments. As of  March 31, 2025, there were 2,126,457 shares available for award under the Incentive Plan. No awards may be made under the Incentive Plan after May 1, 2033. To the extent available, we have issued treasury stock to satisfy all share-based incentive plans.

Included in salaries, wages, and related expenses within the condensed consolidated statements of operations is stock-based compensation expense of $0.8 million for each of the three months ended March 31, 2025 and 2024. Included in general supplies and expenses within the condensed consolidated statements of operations is stock-based compensation expense for non-employee directors of $0.2 million for each of the three months ended March 31, 2025 and 2024. Of the stock compensation expense recorded for the three months ended  March 31, 2025 and March 31, 2024, $0.8 million and $0.1 million relates to restricted shares, respectively. There were no unvested employee stock options or related stock compensation expense for the three months ended  March 31, 2025 and $0.7 million of stock compensation expense related to unvested employee stock options for the three months ended  March 31, 2024. 

The Incentive Plan allows participants to pay the federal and state minimum statutory tax withholding requirements related to awards that vest or allows participants to deliver to us shares of Class A common stock having a fair market value equal to the minimum amount of such required withholding taxes. To satisfy withholding requirements for shares that vested through March 31, 2025, certain participants elected to forfeit receipt of an aggregate of 20,649 shares of Class A common stock at a weighted average per share price of $27.11 based on the closing price of our Class A common stock on the dates the shares vested in 2025, in lieu of the federal and state minimum statutory tax withholding requirements. We remitted $0.6 million to the proper taxing authorities in satisfaction of the employees' minimum statutory withholding requirements.

From time-to-time, we are a party to ordinary, routine litigation arising in the ordinary course of business, most of which involves claims for personal injury and/or property damage incurred in connection with the transportation of freight.

We had $19.9 million and $19.8 million of outstanding and undrawn letters of credit as of March 31, 2025 and December 31, 2024. The letters of credit are maintained primarily to support our insurance programs. Additionally, we had $45.0 million of availability on a line of credit from Triumph solely to fund any indemnification owed to Triumph in relation to the TFS Settlement. As of  March 31, 2025 the remaining contingent liability was $0.6 million.
