NON-GAAP DISCLOSURES

Adjusted Net Income and Adjusted Earnings per Diluted Share

Adjusted net income and adjusted earnings per diluted share are non-GAAP supplemental financial measures that are presented because they are important measures used by management to evaluate period-to-period comparisons of earnings trends. Adjusted net income and adjusted earnings per diluted share should not be considered as alternatives to net income or earnings per diluted share presented in accordance with GAAP.

The table below reconciles adjusted net income and adjusted earnings per diluted share with net income and earnings per diluted share, as derived from the statements of consolidated income to be included in EQT’s report on Form 10-Q for the quarter ended June 30, 2015.

(a)         Tax impact for the three months ended June 30, 2015, is based on an estimated full-year effective tax rate of 10.81%; and for the three months ended June 30, 2014, is the effective tax rate of 30.2%.

Operating Cash Flow and Adjusted Operating Cash Flow Attributable to EQT

Operating cash flow and adjusted operating cash flow attributable to EQT are non-GAAP supplemental financial measures that are presented as indicators of an oil and gas exploration and production company’s ability to internally fund exploration and development activities and to service or incur additional debt. EQT includes this information because management believes that changes in operating assets and liabilities relate to the timing of cash receipts and disbursements, and therefore, may not relate to the period in which the operating activities occurred. Adjusted operating cash flow attributable to EQT excludes the noncontrolling interest portion of adjusted EQT Midstream Partners EBITDA (a non-GAAP supplemental financial measure reconciled below). Management believes that removing the impact on operating cash flows of the public unitholders of EQGP and EQM that is otherwise required to be consolidated in EQT’s results provides useful information to an EQT investor. Operating cash flow and adjusted operating cash flow attributable to EQT should not be considered as alternatives to net cash provided by operating activities presented in accordance with GAAP. The table below reconciles operating cash flow and adjusted operating cash flow attributable to EQT with net cash provided by operating activities, as derived from the statements of consolidated cash flows to be included in EQT’s report on Form 10-Q for the quarter ended June 30, 2015.

(a)    Adjusted EQT Midstream Partners EBITDA and noncontrolling interest portion of adjusted EQT Midstream Partners EBITDA are non-GAAP supplemental financial measures reconciled below.

(b)    Amount represents current tax expense related to the sale of the Northern West Virginia Marcellus Gathering System (NWV Gathering) and the sale of EQGP units in its initial public offering.

EQT Production Adjusted Net Operating Revenues

The operational information in the EQT Corporation Price Reconciliation table below presents an average realized price ($/Mcfe) to EQT Production and EQT Corporation, which is based on EQT Production’s adjusted net operating revenues, a non-GAAP supplemental financial measure. EQT Production adjusted net operating revenues is presented because it is an important measure used by the Company’s management to evaluate period-to-period comparisons of earnings and cash flow trends. EQT Production adjusted net operating revenues should not be considered as an alternative to EQT Corporation operating revenues, the most directly comparable GAAP financial measure, to be included in EQT’s report on Form 10-Q for the quarter ended June 30, 2015. The tables below reconcile EQT Production adjusted net operating revenues, a non-GAAP supplemental financial measure, to EQT Corporation operating revenues.

The Company reports gain (loss) for hedging ineffectiveness and gain (loss) on derivatives not designated as hedges within total operating revenues.

Third-party costs incurred to gather, process and transport gas produced by EQT Production to market sales points are recorded as a portion of transportation and processing costs in the Company’s Statements of Consolidated Income, to be included in EQT’s report on Form 10-Q for the quarter ended June 30, 2015. Some transportation costs incurred by the Company are marketed for resale and are not incurred to transport gas produced by EQT Production. These transportation costs are reflected as a deduction from total operating revenues.

Adjusted EQT Midstream Partners EBITDA and Noncontrolling Interest Portion of Adjusted EQT Midstream Partners EBITDA

As used in this news release, adjusted EQT Midstream Partners (EQM) EBITDA means EQM’s net income plus EQM’s interest expense, depreciation and amortization expense, income tax expense (if applicable), and non-cash long-term compensation expense less EQM’s equity income, other income, capital lease payments, and adjusted EBITDA attributable to the Jupiter Gathering System (Jupiter) and NWV Gathering prior to acquisition. As used in this news release, noncontrolling interest portion of adjusted EQT Midstream Partners EBITDA means the portion of adjusted EQT Midstream Partners EBITDA attributable to the noncontrolling interest unit holders of EQM and EQT GP Holdings, LP (EQGP). Adjusted EQT Midstream Partners EBITDA and noncontrolling interest portion of adjusted EQT Midstream Partners EBITDA are non-GAAP supplemental financial measures that management and external users of the Company’s consolidated financial statements, such as industry analysts, investors, lenders and rating agencies, use to assess the effects of the noncontrolling interests in relation to:

·      the Company’s operating performance as compared to other companies in its industry;

·      the ability of the Company’s assets to generate sufficient cash flow to make distributions to its investors;

·      the Company’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.

The Company believes that adjusted EQT Midstream Partners EBITDA and noncontrolling interest portion of adjusted EQT Midstream Partners EBITDA provide useful information to investors in assessing the Company’s financial condition and results of operations. Adjusted EQT Midstream Partners EBITDA and noncontrolling interest portion of adjusted EQT Midstream Partners EBITDA should not be considered as alternatives to EQM’s net income, operating income, or any other measure of financial performance or liquidity presented in accordance with GAAP. Adjusted EQT Midstream Partners EBITDA and noncontrolling interest portion of adjusted EQT Midstream Partners EBITDA have important limitations as analytical tools because they exclude some, but not all, items that affect EQM’s net income. Additionally, because adjusted EQT Midstream Partners EBITDA and noncontrolling interest portion of adjusted EQT Midstream Partners EBITDA may be defined differently by other companies in the Company’s or EQM’s industries, the definition of adjusted EQT Midstream Partners EBITDA and noncontrolling interest portion of adjusted EQT Midstream Partners EBITDA may not be comparable to similarly titled measures of other companies, thereby diminishing their utility. The table below reconciles adjusted EQT Midstream Partners EBITDA and noncontrolling interest portion of adjusted EQT Midstream Partners EBITDA to EQM’s net income, as derived from the statements of consolidated operations to be included in EQM’s report on Form 10-Q for the quarter ended June 30, 2015.

(a)         Adjusted EBITDA attributable to Jupiter for the three and six months ended June 30, 2014 was calculated as net income of $5.5 million and $20.1 million, respectively plus depreciation and amortization expense of $0.6 million and $2.1 million, respectively, plus income tax expense of $3.4 million and $12.5 million, respectively.

(b)         Adjusted EBITDA attributable to NWV Gathering for the six months ended June 30, 2015 was calculated as net income of $11.1 million plus depreciation and amortization expense of $2.0 million plus income tax expense of $6.7 million. Adjusted EBITDA attributable to NWV Gathering for the three and six months ended June 30, 2014 was calculated as net income of $6.9 million and $12.4 million, respectively, plus depreciation and amortization expense of $1.9 million and $3.5 million, respectively, plus income tax expense of $4.0 million and $7.1 million, respectively.

(c)          Represents weighted average noncontrolling interest ownership percentage for the period, which considers the impact of the 9.9% noncontrolling interest in EQGP.

Cautionary Statements

The United States Securities and Exchange Commission (SEC) permits oil and gas companies, in their filings with the SEC, to disclose only proved, probable and possible reserves that a company anticipates as of a given date to be economically and legally producible and deliverable by application of development projects to known accumulations. We use certain terms, such as “EUR” (estimated ultimate recovery) and “3P” (proved, probable and possible), that the SEC’s guidelines prohibit us from including in filings with the SEC. These measures are by their nature more speculative than estimates of reserves prepared in accordance with SEC definitions and guidelines and accordingly are less certain.

Total sales volume per day (or daily production) is an operational estimate of the daily production or sales volume on a typical day (excluding curtailments).

EBITDA is defined as earnings before interest, taxes, depreciation, and amortization and is not a financial measure calculated in accordance with GAAP. EBITDA is a non-GAAP supplemental financial measure that the Company’s management and external users of the Company’s financial statements, such as industry analysts, investors, lenders and rating agencies, may use to assess: (i) the Company’s performance versus prior periods; (ii) the Company’s operating performance as compared to other companies in its industry; (iii) the ability of the Company’s assets to generate sufficient cash flow to make distributions to its investors; (iv) the Company’s ability to incur and service debt and fund capital expenditures; and (v) the viability of acquisitions and other capital expenditure projects and the returns on investment of various investment opportunities.

The Company is unable to provide a reconciliation of projected EBITDA to projected operating income, the most comparable financial measure calculated in accordance with GAAP, due to the unknown effect, timing and potential significance of certain income statement items.

Similarly, the Company is unable to provide a reconciliation of its projected operating cash flow to projected net cash provided by operating activities, the most comparable financial measure calculated in accordance with GAAP, because of uncertainties associated with projecting future net income and changes in assets and liabilities.
