Exhibit 99.1

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.

Second Quarter 2026 Financial Results

Gathering

and compression volumes increased by 19% and 17%, respectively, compared to the prior year quarter. Fresh water delivery volumes

averaged 82 MBbl/d during the quarter, a 16% decrease compared to the second quarter of 2025. Processing volumes from the processing and

fractionation joint venture (the “Joint Venture”) averaged 1.6 Bcf/d and Joint Venture fractionation volumes averaged 40 MBbl/d,

both in line with the prior year quarter. Processing and fractionation capacity were both 100% utilized during the quarter.

For

the three months ended June 30, 2026, revenues were $327 million, comprised of $272 million from the Gathering and Processing segment

and $79 million from the Water Handling segment, net of $23 million of amortization of customer relationships. Water Handling revenues

Direct

operating expenses were $37 million for the Gathering and Processing segment and $48 million for the Water Handling segment for a total

of $85 million. Water Handling operating expenses include $40 million from other water handling and high rate water transfer services.

General and administrative expenses excluding equity-based compensation were $12 million during the second quarter of 2026. Total operating

of property and equipment, transaction expense and other, net of tax effects of reconciling items, or Adjusted Net Income, was $131 million.

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.

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, 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.
