RECONCILIATION OF NON-GAAP FINANCIAL MEASURES AND OTHER DATA

(dollars in thousands, except for amounts listed in the footnotes to the tables below or unless indicated otherwise)

TA believes the non-GAAP financial measures presented in the tables below are meaningful supplemental disclosures. Management uses these measures in developing internal budgets and forecasts and analyzing TA’s performance and believes that they may help investors gain a better understanding of changes in TA’s operating results and its ability to pay rent or service debt when due, make capital expenditures and expand its business. These non-GAAP financial measures also may help investors to make comparisons between TA and other companies and to make comparisons of TA’s financial and operating results between periods.

The non-GAAP financial measures TA presents should not be considered as alternatives to net (loss) income attributable to common stockholders, net (loss) income, (loss) income from operations, or net (loss) income per share of common stock attributable to common stockholders as an indicator of TA’s operating performance or as a measure of TA’s liquidity. Also, the non-GAAP financial measures TA presents may not be comparable to similarly titled amounts calculated by other companies.

TA believes that adjusted net (loss) income, EBITDA and adjusted EBITDA are meaningful disclosures that may help investors to better understand TA’s financial performance by providing financial information that represents the operating results of TA’s operations without the effects of items that do not result directly from TA’s normal recurring operations and may allow investors to better compare TA’s performance between periods and to the performance of other companies. TA calculates EBITDA as net income before interest, income taxes and depreciation and amortization expense, as shown below. TA calculates adjusted EBITDA by excluding items that it considers not to be normal, recurring, cash operating expenses or gains or losses.

In addition, TA believes that, because it leases a majority of its travel centers, presenting adjusted EBITDAR may help investors compare the value of TA against companies that own and finance ownership of their properties with debt financing, since this measure eliminates the effects of variability in leasing methods and capital structures. This measure may also help investors evaluate TA’s valuation if it owned its leased properties and financed that ownership with debt, in which case the interest expense TA incurred for that debt financing would be added back when calculating EBITDA. Adjusted EBITDAR is presented solely as a valuation measure and should not be viewed as a measure of overall operating performance or considered in isolation or as an alternative to net income because it excludes the real estate rent expense associated with TA’s leases and it is presented for the limited purposes referenced herein. TA calculates EBITDAR as net income before interest, income taxes, real estate rent expense and depreciation and amortization expense and adjusted EBITDAR by excluding items that it considers not to be normal, recurring, cash operating expenses or gains or losses.

TA believes that net (loss) income is the most directly comparable GAAP financial measure to adjusted net (loss) income, EBITDA, adjusted EBITDA and adjusted EBITDAR.

The following tables present the reconciliations of the non-GAAP financial measures to the respective most directly comparable GAAP financial measures for the three months ended March 31, 2023 and 2022.
