Antero Midstream Announces Second Quarter 2026 Financial and Operating Results

Denver, Colorado, July 29, 2026—Antero Midstream Corporation (NYSE: AM) (“Antero Midstream” or the “Company”) today announced its second quarter 2026 financial and operating results. The relevant consolidated financial statements are included in Antero Midstream’s Quarterly Report on Form 10-Q for the three months ended June 30, 2026.

Highlights:

·Gathering and compression volumes increased by 19% and 17%, respectively, compared to the prior year quarter

·Net Income was $114 million, or $0.24 per diluted share, an 8% per share decrease compared to the prior year quarter

·Adjusted Net Income was $131 million, or $0.27 per diluted share, a 7% per share decrease compared to the prior year quarter (non-GAAP measure)

·Adjusted EBITDA was $289 million, a 2% increase compared to the prior year quarter (non-GAAP measure)

·Capital expenditures were $47 million

·Adjusted Free Cash Flow after dividends was $80 million (non-GAAP measure)

·Commenced construction on the Company’s first intrastate regional pipeline (“East Side Express”)

·Received $371 million in damages and interest from Veolia in July and called $650 million of senior notes due 2028 at par

Michael Kennedy, CEO and President of Antero Midstream said, “During the quarter, Antero Midstream gathered over 4.1 Bcf/d of production, which was a 19% increase year-over-year and a new company record. Our water integration projects remain on track, which we expect to drive high-single digit EBITDA growth in 2027.”

Mr. Kennedy further added, “In addition, during the quarter we commenced initial construction of our first intrastate regional pipeline, the “East Side Express”, which will enhance regional connectivity within our operating areas. This pipeline positions Antero Midstream for future dry gas growth in West Virginia with decades of underlying inventory to capture growing regional demand. This east-west bi-directional pipeline represents our first regional pipeline and adds significant optionality for future intrastate pipeline projects that provide an integrated midstream solution connecting low-cost supply to demand centers.”

Justin Agnew, CFO of Antero Midstream, said “The second quarter marked our twelfth consecutive quarter of generating Free Cash Flow after dividends, highlighting the consistency of operations over the last three years. Looking ahead, we expect an increase in volumes across both the gathering and water businesses to drive EBITDA growth in the back half of the year in line with our full year guidance range.”

Mr. Agnew further added, “In July, Antero Midstream received approximately $371 million of proceeds from Veolia, which allowed us to reduce absolute debt and be below our 3-times leverage target ahead of expectations. After calling the $650 million of senior notes due 2028 at par, Antero Midstream has over $600 million of liquidity and no near-term maturities. This provides us with significant liquidity and balance sheet capacity to pursue additional growth opportunities and further return of capital to shareholders.”

For a discussion of the non-GAAP financial measures, including Adjusted EBITDA, Adjusted Net Income, Leverage, and Adjusted Free Cash Flow after dividends please see “Non-GAAP Financial Measures and Definitions.”

Clearwater Lawsuit Update

On June 23, 2026 the Colorado Supreme Court affirmed that Antero Midstream had prevailed on its claims against Veolia relating to the Clearwater Facility. On July 24, 2026 Antero Midstream received approximately $371 million in damages and interest. These proceeds and borrowings under the revolving credit facility are being used to call the $650 million of senior unsecured notes due 2028 at par.

Share Repurchases

During the second quarter of 2026, Antero Midstream repurchased 0.4 million shares for approximately $8 million. Antero Midstream had approximately $310 million of remaining capacity under its share repurchase program as of June 30, 2026.

Strategic and Operating Updates

During the quarter, Antero Midstream began its multiyear investment in the East Side Express, the Company’s first dry gas regional connectivity expansion project. This project will expand dry gas deliveries to several different long haul and regional pipelines and will enhance optionality to local markets in order to capture growing regional demand around the Company’s area of operations.

Antero Midstream connected 26 wells to its gathering system and serviced 21 wells with its fresh water delivery system during the quarter. Capital expenditures were $47 million during the second quarter of 2026. The Company invested $33 million in gathering and compression and $14 million in water infrastructure.
