 Appendix 

   Adjusted EBITDA reconciliation (unaudited)  Moving Infrastructure Forward — ACG Materials Presentation, November 2018  13  $ Millions (For the Trailing Twelve Months Ended August 31, 2018)         Net income  (1.8)  Add:      Interest expense  16.6    Provision/(benefit) for income taxes  (3.9)   Depreciation & amortization expense  15.4   Other adjustments  5.7       Adjusted EBITDA  32.0  “Adjusted EBITDA” is defined as ACG’s net income plus interest expense, income taxes, depreciation and amortization, and other one-time or non-recurring expenses, including management fees, debt refinancing fees, and non-recurring professional fees. Adjusted EBITDA is not a calculation based on generally accepted accounting principles. The amounts included in the Adjusted EBITDA calculation, however, are derived from amounts included in the historical statements of operations data. In addition, Adjusted EBITDA should not be considered as an alternative to net income or operating income as an indicator of ACG’s operating performance, or as an alternative to operating cash flows as a measure of liquidity. We believe Adjusted EBITDA assists investors in comparing a company’s performance on a consistent basis without regard to depreciation and amortization and other expenses, which can vary significantly depending upon many factors.
