EQT Midstream Partners, LP Non-GAAP Measures EQM adjusted EBITDA means EQM’s net income plus net interest expense, depreciation and amortization expense, income tax expense, preferred interest payments received post conversion and non-cash long-term compensation expense less equity income, AFUDC – equity, pre-acquisition capital lease payments for Allegheny Valley Connector, LLC (AVC) and adjusted EBITDA of assets prior to acquisition. As used in this presentation, distributable cash flow means EQM adjusted EBITDA less net interest expense excluding interest income on the preferred interest, capitalized interest and AFUDC - debt, and ongoing maintenance capital expenditures net of expected reimbursements. Distributable cash flow should not be viewed as indicative of the actual amount of cash that EQM has available for distributions from operating surplus or that EQM plans to distribute. Adjusted EBITDA and distributable cash flow are non-GAAP supplemental financial measures that management and external users of EQM’s consolidated financial statements, such as industry analysts, investors, lenders and rating agencies, use to assess: EQM’s operating performance as compared to other publicly traded partnerships in the midstream energy industry without regard to historical cost basis or, in the case of adjusted EBITDA, financing methods; the ability of EQM’s assets to generate sufficient cash flow to make distributions to EQM unitholders; EQM’s 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. EQM believes that adjusted EBITDA and distributable cash flow provide useful information to investors in assessing EQM’s results of operations and financial condition. Adjusted EBITDA and distributable cash flow should not be considered as alternatives to net income, operating income, net cash provided by operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP. Adjusted EBITDA and distributable cash flow have important limitations as analytical tools because they exclude some, but not all, items that affect net income and net cash provided by operating activities. Additionally, because adjusted EBITDA and distributable cash flow may be defined differently by other companies in its industry, EQM’s definitions of adjusted EBITDA and distributable cash flow may not be comparable to similarly titled measures of other companies, thereby diminishing the utility of the measures. EQM is unable to project net cash provided by operating activities or provide the related reconciliation of projected net cash provided by operating activities to projected distributable cash flow, the most comparable financial measure calculated in accordance with GAAP, because net cash provided by operating activities includes the impact of changes in operating assets and liabilities. Changes in operating assets and liabilities relate to the timing of EQM’s cash receipts and disbursements that may not relate to the period in which the operating activities occurred, and EQM is unable to project these timing differences with any reasonable degree of accuracy to a specific day, three or more months in advance. EQM is also unable to provide a reconciliation of its projected adjusted EBITDA to projected net income, the most comparable financial measure calculated in accordance with GAAP, because EQM does not provide guidance with respect to the intra-year timing of its or Mountain Valley Pipeline, LLC’s capital spending, which impact AFUDC-debt and equity and equity earnings, among other items, that are reconciling items between adjusted EBITDA and net income. The timing of capital expenditures is volatile as it depends on weather, regulatory approvals, contractor availability, system performance and various other items. EQM provides a range for the forecasts of net income, adjusted EBITDA and distributable cash flow to allow for the variability in the timing of cash receipts and disbursements, capital spending and the impact on the related reconciling items, many of which interplay with each other. Therefore, the reconciliations of projected distributable cash flow and adjusted EBITDA to projected net cash provided by operating activities and net income are not available without unreasonable effort. Return on capital employed (ROCE) as used in this presentation means a ratio, the numerator of which is EQM’s net income less income taxes and interest expense (EBIT), and the denominator of which is the average of total assets less current liabilities for the beginning and end of the applicable measurement period. EBIT is a non-GAAP supplemental financial measure that management and external users of EQM’s consolidated financial statements use to assess the items listed above with respect to EQM adjusted EBITDA. EQM believes that ROCE is a useful measure for investors in assessing how effectively EQM has invested its capital including in relation to EQM’s peers. EBIT should not be considered as an alternative to net income, operating income or any other measure of financial performance presented in accordance with GAAP. Because ROCE may be defined differently by other companies in its industry, EQM’s definition of ROCE may not be comparable to similarly titled measures of other companies, thereby diminishing the utility of the measure.

EQT Midstream Partners, LP Non-GAAP Measures (cont.) As used in this presentation, EBITDA means the earnings before interest, taxes and depreciation of EQT’s retained midstream assets acquired from Rice. EBITDA of these assets is a non-GAAP supplemental financial measure that management and external users of EQM’s consolidated financial statements, such as industry analysts, investors, lenders and rating agencies, use to assess the impact of EQT's potential drop-down of the retained midstream assets to EQM on EQM’s future results of operations. EQM believes that the projected EBITDA of the retained midstream assets provides useful information to investors in assessing the impact of the potential drop-down transaction or transactions on EQM’s future results of operations. EBITDA should not be considered as an alternative to net income, operating income, or any other measure of financial performance or liquidity presented in accordance with GAAP. EBITDA has important limitations as an analytical tool because it excludes some, but not all, items that affect net income. Additionally, because EBITDA may be defined differently by other companies in EQM’s industry, the definition of EBITDA may not be comparable to similarly titled measures of other companies, thereby diminishing the utility of the measure. EQM has not provided projected net income from the Rice retained midstream assets, the most comparable financial measure calculated in accordance with GAAP, or a reconciliation of projected EBITDA to projected net income of the assets. The retained midstream assets are operated as part of EQT’s Production business segment, and EQT does not allocate certain costs, such as interest and tax, to individual assets within its business segments. Therefore, projected net income of the retained midstream assets and a reconciliation of projected EBITDA of the assets to projected net income from those assets are not available without unreasonable effort.
