Non-GAAP Financial Measures

26

This presentation includes Adjusted EBITDA, Distributable Cash Flow, Distribution Coverage Ratio and ROACE, all of which are non-GAAP measures which may be used periodically by management when discussing our financial results with investors and analysts.

We define Adjusted EBITDA as net income before income taxes, net interest expense, depreciation and amortization and unit-based compensation. Adjusted EBITDA is used as a supplemental financial measure by management and by external users of our financial statements, such as investors, industry analysts, lenders and ratings agencies, to assess: our operating performance as compared to those of other companies in the midstream energy industry, without regard to financing methods, historical cost basis or capital structure; the ability of our assets to generate sufficient cash flow to make distributions to our partners; our ability to incur and service debt and fund capital expenditures; and the viability of acquisitions and other capital expenditure projects and the returns on investment of various investment opportunities. We define Distributable Cash Flow as Adjusted EBITDA less estimated maintenance capital expenditures and cash interest expense. Distributable Cash Flow is used by management to evaluate our overall performance. Our partnership agreement requires us to distribute all cash on a quarterly basis, and Distributable Cash Flow is one of the factors used by the board of directors of our general partner to help determine the amount of available cash that is available to our unitholders for a given period. We calculate our Distribution Coverage Ratio as Distributable Cash Flow divided by total distributions declared. The Distribution Coverage Ratio is used by management to illustrate our ability to make our distributions each quarter.

We define ROACE as earnings before interest and taxes divided by (average total assets – average current liabilities). ROACE is used by management to measure the efficiency of the utilization of the capital that we employ.

We believe that the presentation of Adjusted EBITDA, Distributable Cash Flow, Distribution Coverage Ratio and ROACE provide information useful to investors in assessing our financial condition and results of operations. The GAAP measure most directly comparable to Adjusted EBITDA, Distributable Cash Flow, Distribution Coverage Ratio and ROACE is Net Income. Adjusted EBITDA, Distributable Cash Flow, Distribution Coverage Ratio and ROACE should not be considered alternatives to net income or any other measure of financial performance or liquidity presented in accordance with GAAP. Adjusted EBITDA, Distributable Cash Flow, Distribution Coverage Ratio and ROACE exclude some, but not all, items that affect net income, and these measures may vary from those of other companies. As a result, Adjusted EBITDA, Distributable Cash Flow, Distribution Coverage Ratio and ROACE as presented herein may not be comparable to similarly titled measures of other companies.

Noble Midstream does not provide guidance on the reconciling items between forecasted Net Income, forecasted Adjusted EBITDA, forecasted Distributable Cash Flow and forecasted Distribution Coverage Ratio due to the uncertainty regarding timing and estimates of these items. Noble Midstream provides a range for the forecasts of Net Income, Adjusted EBITDA, Distributable Cash Flow and Distribution Coverage Ratio to allow for the variability in timing and uncertainty of estimates of reconciling items between forecasted Net Income, forecasted Adjusted EBITDA, forecasted Distributable Cash Flow and forecasted Distribution Coverage Ratio. Therefore, the Partnership cannot reconcile forecasted Net Income to forecasted Adjusted EBITDA, forecasted Distributable Cash Flow or forecasted Distribution Coverage Ratio without unreasonable effort.

In addition to Net Income, the GAAP measure most directly comparable to Adjusted EBITDA and Distributable Cash Flow is net cash provided by operating activities. Adjusted EBITDA and Distributable Cash Flow should not be considered alternatives to net income, net cash provided by operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP. Due to the forward-looking nature of net cash provided by operating activities, management cannot reliably predict certain of the necessary components of the most directly comparable forward-looking GAAP measures, such as future impairments and future changes in working capital. Accordingly, Noble Midstream is unable to present a quantitative reconciliation of the aforementioned forward-looking non-GAAP financial measures to net cash provided by operating activities. Amounts excluded from these non-GAAP measures in future periods could be significant.
