A Premiere Diversified Industrial Company Trinity Industries, Inc. 21 Reconciliation of EBITDA (1) (in millions) “EBITDA” is defined as income (loss) from continuing operations plus interest expense, income taxes, and depreciation and amortization including goodwill impairment charges. EBITDA is not a calculation based on generally accepted accounting principles. The amounts included in the EBITDA calculation, however, are derived from amounts included in the historical statements of operations data. In addition, EBITDA should not be considered as an alternative to net income or operating income as an indicator of our operating performance, or as an alternative to operating cash flows as a measure of liquidity. We believe EBITDA assists investors in comparing a company’s performance on a consistent basis without regard to depreciation and amortization, which can vary significantly depending upon many factors. However, the EBITDA measure presented in this presentation may not always be comparable to similarly titled measures by other companies due to differences in the components of the calculation. (1) EBITDA for previous years has been adjusted as a result of the divestiture of the Company’s Concrete business (2) Includes results of operations related to TRIP starting January 1, 2010 (2) 2008 2009 2010 2011 2012 2013 2014 LTM 06/15 Income (loss) from continuing operations $266.8 ($140.8) $69.4 $146.8 $251.9 $386.1 $709.3 $713.0 Add: Interest expense 109.4 123.1 182.1 185.3 194.7 187.3 193.4 202.3 Provision/(Benefit) for income taxes 163.5 (11.5) 37.3 92.2 134.0 204.4 354.8 366.5 Depreciati n & amortization expense 126.8 147.1 180.9 187.7 193.7 211.5 244.6 264.0 Goodwill impairment - 325.0 - - - - - - Earnings from continuing operations before interest expense, income taxes, and depreciation and amortization expense $666.5 $442.9 $469.7 $612.0 $774.3 $989.3 $1,502.1 $1,545.8
