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.  Moving Infrastructure Forward — Investor Presentation, November 2018  Guidance as of November 1, 2018

Since income taxes and interest expense are not allocated to the segment level, they are not added back in the calculation of adjusted EBITDA. For a reconciliation of EBITDA to net income, see the accompanying EBITDA reconciliation. 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 our 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, which can vary significantly depending upon many factors.   Moving Infrastructure Forward — Investor Presentation, November 2018
