**Antero Midstream Announces First Quarter 2026 Financial and Operating Results**

**Denver, Colorado, April 29, 2026—Antero Midstream Corporation (NYSE: AM)** ("Antero Midstream" or the "Company") today announced its first 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 March 31, 2026.

**First Quarter 2026 Highlights:**

&nbsp;&nbsp;&nbsp;&nbsp;· **Gathering volumes increased by 14% compared to the prior year quarter** 

&nbsp;&nbsp;&nbsp;&nbsp;· **Net Income was $118 million, or $0.25 per diluted share, in line with the prior year quarter** 

&nbsp;&nbsp;&nbsp;&nbsp;· **Adjusted Net Income was $138 million, or $0.29 per diluted share, a 4% per share increase compared to the prior year quarter (non-GAAP measure)** 

&nbsp;&nbsp;&nbsp;&nbsp;· **Adjusted EBITDA was $288 million, a 5% increase compared to the prior year quarter (non-GAAP measure)** 

&nbsp;&nbsp;&nbsp;&nbsp;· **Capital expenditures were $42 million** 

&nbsp;&nbsp;&nbsp;&nbsp;· **Adjusted Free Cash Flow after dividends was $85 million, an 8% increase compared to the prior year quarter (non-GAAP measure)** 

&nbsp;&nbsp;&nbsp;&nbsp;· **Repurchased 1.0 million shares for $18 million** 

Michael Kennedy, CEO and President said, "Antero Midstream delivered another quarter of volume and EBITDA growth while closing the Company's largest acquisition to-date. Our ability to close the HG acquisition and integrate operations while avoiding any outages during Winter Storm Fern, is a testament to the hard work and dedication of our team."

Mr. Kennedy continued, "In addition to the integration efforts that remain on schedule, we continue to invest capital to improve the connectivity and market outlets on our gathering systems. These capital projects supported our first dry gas Marcellus Shale pad in over a decade, as well as our first pad on the acquired assets, that were connected during the second quarter. These pads deliver volumetric growth and position Antero Midstream to help supply the rising demand for U.S. Energy."

Justin Agnew, CFO of Antero Midstream, said "Antero Midstream's strong balance sheet and consistent Free Cash Flow generation, combined with the sale of our Ohio Utica Shale assets, allowed us to finance the HG Energy acquisition while maintaining leverage in the low 3-times range. Looking ahead we expect our just-in-time organic strategy, bolstered by the highly accretive HG Energy acquisition, to continue delivering high-single digit EBITDA growth in the future."

*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."*

**Share Repurchases**

During the first quarter of 2026, Antero Midstream repurchased 1.0 million shares for $18 million. Antero Midstream had approximately $318 million of remaining capacity under its share repurchase program as of March 31, 2026.

**Strategic and Operating Updates**

Antero Midstream completed its two previously announced strategic transactions during the first quarter. The Company closed on the HG Energy acquisition in early February and closed on the divestiture of its Ohio Utica Shale assets in late February. Operating and financial results include contributions based on the closing dates of each transaction.

Upon closing of the acquisition, Antero Midstream immediately commenced asset integration operations and cost-effective water blending solutions. This included initial facilities and connectivity work that successfully supported the first pad turn-in-line on the acquired assets in the second quarter. In addition, the Company initiated the construction of a pipeline to connect its water system with the acquired water system, which supports additional fresh water delivery volumes and growth in 2027 and beyond.

During the first quarter of 2026, Antero Midstream connected 20 wells to its gathering system and serviced 26 wells with its fresh water delivery system. Capital expenditures were $42 million during the first quarter of 2026. The Company invested $26 million in gathering and compression, $15 million in water infrastructure, and $1 million in the Stonewall Joint Venture.

**First Quarter 2026 Financial Results**

Gathering volumes increased by 14% compared to the prior year quarter. Fresh water delivery volumes averaged 83 MBbl/d during the quarter, a 21% decrease compared to the first quarter of 2025. Processing volumes from the processing and fractionation joint venture (the "Joint Venture") increased by 4% compared to the prior year quarter. Joint Venture fractionation volumes averaged 40 MBbl/d, in line with the prior year quarter. Processing and fractionation capacity were both 100% utilized during the quarter.

**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:

· the financial performance of Antero Midstream's
assets, without regard to financing methods, capital structure or historical cost basis;

· its operating performance and return on capital
as compared to other publicly traded companies in the midstream energy sector, without regard to financing or capital structure; and

· the viability of acquisitions and other capital
expenditure projects.

Antero Midstream defines Adjusted 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 and Adjusted Free Cash Flow excludes transaction expense related to acquisitions. Adjusted Free Cash Flow after dividends is defined as Adjusted Free Cash Flow before dividends less accrual-based dividends declared for the quarter. Antero Midstream uses Adjusted 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 Adjusted 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 (used in) 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.

| &nbsp;&nbsp;&nbsp;Change in accrued capital costs | 5012 | 3146 |
| **Capital expenditures (accrual basis)** | $**37288** | **41952** |

Antero Midstream defines Net Debt as consolidated total debt, excluding unamortized debt premiums and debt issuance costs, less cash, cash equivalents and restricted cash. 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.
