Non-GAAP Financial Data

This presentation includes the use of EBITDA, Adjusted EBITDA, adjusted operating ratio and Adjusted EPS, financial measures that are not in accordance with generally accepted accounting principles (“GAAP”). Eachsuch measure is a supplemental non-GAAP financial measure that is used by management and external users of our financial statements, such as industry analysts, investors and lenders. While management believessuch measures are useful for investors, they should not be used as a replacement for financial measures that are in accordance with GAAP. Please see the Appendix to this presentation for a reconciliation to theclosest GAAP financial measures.

The Company defines EBITDA as net loss, plus interest expense net of interest income, provision for income taxes and depreciation and amortization. It defines Adjusted EBITDA as these items plus non-cash equitycompensation, restructuring, impairment and other costs, and severance costs included in salaries, wages and employee benefits. Adjusted operating ratio is calculated as operating expenses less restructuring,impairment (excluding impairment of assets held for sale) and other costs, net of fuel surcharges, as a percentage of operating revenue excluding fuel surcharge revenue. Adjusted EPS is defined as earnings or lossbefore income taxes plus loss on extinguishment of debt, restructuring, impairment and other costs, and severance costs included in salaries, wages and employee benefits reduced by our statutory income tax rate,divided by weighted average diluted shares outstanding. Because not all companies use identical calculations, the Company's presentation of non-GAAP financial measures may not be comparable to similarly titledmeasures of other companies.

All forward-looking statements attributable to us, or persons acting on our behalf, are expressly qualified in their entirety by this cautionary statement.

References to the “Company,” “we,” “us,” “our” and words of similar import refer to USA Truck, Inc. and its subsidiary.
