Disclosure Statement Forward-Looking Statements This presentation contains forward-looking statements within the meaning of Section 27 A of the Securities Act of 1933, as amended and Section 21 E of the Securities Exchange Act of 1934, as amended. Such forward-looking statements are made pursuant to the provisions of the Private Securities Litigation Reform Act of 1995. These statements generally may be identified by their use of terms or phrases such as “expects, ” “estimates, ” “anticipates, ” “projects, ” “believes, ” “plans, ” “goals, ” “intends, ” “may, ” “will, ” “should, ” “could, ” “potential, ” “continue, ” “strategy, ” “future” and terms or phrases of similar substance. Forward-looking statements are based upon the current beliefs and expectations of our management and are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, which could cause future events and actual results to differ materially from those set forth in, contemplated by, or underlying the forward-looking statements. Accordingly, actual results may differ materially from those set forth in the forward-looking statements. Readers should review and consider the factors that may affect future results and other disclosures by the Company in its press releases, Annual Report on Form 10 -K and other filings with the Securities and Exchange Commission. Any forwardlooking statement speaks only as of the date on which it is made. We disclaim any obligation to update or revise any forward-looking statements to reflect actual results or changes in the factors affecting the forward-looking information, except as required by law. In light of these risks and uncertainties, the forward-looking events and circumstances discussed in this press release might not occur. All forward-looking statements attributable to us, or persons acting on our behalf, are expressly qualified in their entirety by this cautionary statement. 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”). Each such 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 believes such 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 the closest 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 equity compensation, 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 loss before 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 titled measures 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. 3
