DELIVERING GOODS for THE GOOD of ALL /// 2 Some statements in this presentation, which are not historical facts, are “forward-looking statements” as defined by the Private Securities Litigation Reform Act of 1995. Forward-looking statements include statements about Trinity's estimates, expectations, beliefs, intentions or strategies for the future, and the assumptions underlying these forward-looking statements, including, but not limited to, future financial and operating performance, future opportunities and any other statements regarding events or developments that Trinity believes or anticipates will or may occur in the future, including the potential financial and operational impacts of the COVID-19 pandemic. Trinity uses the words “anticipates,” “assumes,” “believes,” “estimates,” “expects,” “intends,” “forecasts,” “may,” “will,” “should,” “guidance,” “projected,” “outlook,” and similar expressions to identify these forward-looking statements. Forward-looking statements speak only as of the date of this material, and Trinity expressly disclaims any obligation or undertaking to disseminate any updates or revisions to any forward- looking statement contained herein to reflect any change in Trinity’s expectations with regard thereto or any change in events, conditions or circumstances on which any such statement is based, except as required by federal securities laws. Forward- looking statements involve risks and uncertainties that could cause actual results to differ materially from historical experience or our present expectations, including but not limited to risks and uncertainties regarding economic, competitive, governmental, and technological factors affecting Trinity’s operations, markets, products, services and prices, and such forward-looking statements are not guarantees of future performance. For a discussion of such risks and uncertainties, which could cause actual results to differ from those contained in the forward-looking statements, see “Risk Factors” and “Forward- Looking Statements” in Trinity’s Annual Report on Form 10-K for the most recent fiscal year, as may be revised and updated by Trinity’s Quarterly Reports on Form 10-Q, and Trinity’s Current Reports on Form 8-K. This presentation also includes references to calculations that are not based on generally accepted accounting principles (“GAAP”). Reconciliations of each of these non-GAAP measures to the most directly comparable GAAP measures have been included in the Appendix. When forward-looking non-GAAP measures are provided, Trinity does not provide quantitative reconciliations of forward-looking non-GAAP measures to the most directly comparable GAAP measures because it cannot, without unreasonable effort, predict the timing and amounts of certain items included in the computations of each of these measures. These factors include, but are not limited to: the product mix of expected railcar deliveries; the timing and amount of significant transactions and investments, such as railcar sales from the lease fleet, capital expenditures, and returns of capital to shareholders; and the amount and timing of certain other items outside the normal course of our core business operations, such as restructuring activities, and the potential financial and operational impacts of the COVID-19 pandemic. Forward Looking Statements and Other References Except where noted, financial data is presented as of the Company’s most recent fiscal quarter ending December 31, 2020. “LTM” represents Last Twelve Months financial information from January 1, 2020 to December 31, 2020.

DELIVERING GOODS for THE GOOD of ALL /// Reconciliation: EBITDA and Adjusted EBITDA “EBITDA” is defined as income (loss) from continuing operations plus interest expense, income taxes, and depreciation and amortization expense. Adjusted EBITDA is defined as EBITDA plus non-cash impairment of long-lived assets, restructuring activities, and pension plan settlement. EBITDA and Adjusted EBITDA are non-GAAP financial measures; however, the amounts included in these calculations are derived from amounts included in our GAAP financial statements. EBITDA and Adjusted EBITDA are reconciled to net income (loss), the most directly comparable GAAP financial measure, in the table above. This information is provided to assist management and investors in making meaningful comparisons of our operating performance between periods. We believe EBITDA is a useful measure for analyzing the performance of our business. We also believe that EBITDA is commonly reported and widely used by investors and other interested parties as a measure of a company’s operating performance and debt servicing ability because it assists in comparing performance on a consistent basis without regard to capital structure, depreciation or amortization (which can vary significantly depending on many factors). EBITDA and Adjusted EBITDA should not be considered as alternatives to net income as indicators of our operating performance, or as alternatives to operating cash flows as measures of liquidity.

Leasing Steady State CapEx Required is defined as leasing depreciation plus the net book value of railcar sales.

(3) Pre-Tax Return on Equity is calculated as adjusted profit before tax divided by average adjusted stockholders' equity, each as defined and reconciled above. Pre-Tax Return on Equity (“Pre-Tax ROE”) is defined as a ratio for which (i) the numerator is calculated as income or loss from continuing operations, adjusted to exclude the effects of the provision or benefit for income taxes, net income or loss attributable to noncontrolling interest, and certain other adjustments, which include restructuring activities, the controlling interest portion of impairment of long-lived assets, early redemption of debt, and pension plan settlement; and (ii) the denominator is calculated as average stockholders’ equity (which excludes noncontrolling interest), adjusted to exclude accumulated other comprehensive income or loss. In the table above, the numerator and denominator of our Pre-Tax ROE calculation are reconciled to income from continuing operations and stockholders’ equity, respectively, which are the most directly comparable GAAP financial measures. Management believes that Pre-Tax ROE is a useful measure to both management and investors as it provides an indication of the economic return on the Company’s investments over time.
