Antero Midstream Announces Second Quarter 2025 Financial and Operating Results and Increased Guidance

Denver, Colorado, July 30, 2025—Antero Midstream Corporation (NYSE: AM) (“Antero Midstream” or the “Company”) today announced its second quarter 2025 financial and operating results. The relevant unaudited condensed consolidated financial statements are included in Antero Midstream’s Quarterly Report on Form 10-Q for the three months ended June 30, 2025.

Second Quarter 2025 Highlights:

2025 Guidance Updates:

Paul Rady, Chairman and CEO said, “During the quarter Antero Midstream gathered 3.5 Bcf/d of production, which was a 6% increase year-over-year and a new company record. This growth coincides with the significant demand growth seen along the U.S. Gulf Coast LNG facilities over the last year. Looking ahead, we continue to see significant demand growth from Gulf Coast LNG facilities as well as natural gas fired power demand from data center growth in Appalachia. As the critical first link to delivering gas to LNG and power demand, Antero Midstream is well positioned for future growth opportunities.”

Brendan Krueger, CFO of Antero Midstream, said “The record gathering and processing volumes in the second quarter led to an 11% year-over-year increase in EBITDA, while capital expenditures declined by 13%. This capital efficiency drove an 89% increase in Free Cash Flow compared to the second quarter of 2024.”

Mr. Krueger continued, “Antero Midstream’s consistent Free Cash Flow generation has enabled the Company to reduce debt by approximately $170 million over the past year, including nearly $100 million year-to-date. This debt reduction, combined with double-digit year-over-year EBITDA growth resulted in leverage declining to 2.8x as of June 30, 2025. In addition to the debt reduction, Antero Midstream has purchased approximately $83 million of shares year-to-date through July 30, 2025.”

Non-GAAP Financial Measures and Definitions

Antero Midstream uses certain non-GAAP financial measures. Antero Midstream defines Adjusted Net Income as Net Income adjusted for certain items. Antero Midstream uses Adjusted Net Income to assess the operating performance of its assets. Antero Midstream defines Adjusted EBITDA as Net Income adjusted for certain items.

Antero Midstream uses Adjusted EBITDA to assess:

Antero Midstream defines Free Cash Flow before dividends as Adjusted EBITDA less net interest expense, accrual-based capital expenditures, and current income tax expense. Capital expenditures include additions to gathering systems and facilities, additions to water handling systems, and investments in unconsolidated affiliates. Capital expenditures exclude acquisitions. Free Cash Flow after dividends is defined as Free Cash Flow before dividends less accrual-based dividends declared for the quarter. Antero Midstream uses Free Cash Flow before and after dividends as a performance metric to compare the cash generating performance of Antero Midstream from period to period.

Adjusted EBITDA, Adjusted Net Income, and Free Cash Flow before and after dividends are non-GAAP financial measures. The GAAP measure most directly comparable to these measures is Net Income. Such non-GAAP financial measures should not be considered as alternatives to the GAAP measures of Net Income and cash flows provided by (used in) operating activities. The presentations of such measures are not made in accordance with GAAP and have important limitations as analytical tools because they include some, but not all, items that affect Net Income and cash flows provided by operating activities. You should not consider any or all such measures in isolation or as a substitute for analyses of results as reported under GAAP. Antero Midstream’s definitions of such measures may not be comparable to similarly titled measures of other companies.

The following table reconciles cash paid for capital expenditures and accrued capital expenditures during the period (in thousands):

Antero Midstream defines Net Debt as consolidated total debt, excluding unamortized debt premiums and debt issuance costs, less cash and cash equivalents. Antero Midstream views Net Debt as an important indicator in evaluating Antero Midstream’s financial leverage. Antero Midstream defines Leverage as Net Debt divided by Adjusted EBITDA for the last twelve months. The GAAP measure most directly comparable to Net Debt is total debt, excluding unamortized debt premiums and debt issuance costs.

The following table reconciles consolidated total debt to Net Debt as used in this release (in thousands):

The following table reconciles Net Income to Adjusted EBITDA for the last twelve months ended June 30, 2025 (in thousands):

Antero Midstream has not included a reconciliation of Adjusted Net Income, Adjusted EBITDA and Free Cash Flow before and after dividends to the nearest GAAP financial measures for 2025 because it cannot do so without unreasonable effort and any attempt to do so would be inherently imprecise. Antero Midstream is able to forecast the following reconciling items between such measures and Net Income (in millions):

Antero Midstream Corporation is a Delaware corporation that owns, operates and develops midstream gathering, compression, processing and fractionation assets located in the Appalachian Basin, as well as integrated water assets that primarily service Antero Resources Corporation’s (NYSE: AR) (“Antero Resources”) properties.
