Exhibit 99.1

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:

· Gathering volumes increased by 14% compared

to the prior year quarter

· Net Income was $118 million, or $0.25 per

diluted share, in line with the prior year quarter

· 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)

· Adjusted EBITDA was $288 million, a 5% increase

compared to the prior year quarter (non-GAAP measure)

· Capital expenditures were $42 million

· Adjusted Free Cash Flow after dividends was

$85 million, an 8% increase compared to the prior year quarter (non-GAAP measure)

· 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.

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, 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.
