Full Year 2024 Highlights:

2025 Guidance Highlights:

Paul Rady, Chairman and CEO said, “Antero Midstream delivered an exceptional year in 2024 with throughput, Net Income, Adjusted EBITDA, and Free Cash Flow setting company records. This Free Cash Flow growth in 2024 provided us with the ability to internally finance an accretive bolt-on acquisition, reduce absolute debt, pay an attractive dividend and repurchase shares in 2024.”

Brendan Krueger, CFO of Antero Midstream, said “In 2024, Antero Midstream reduced its absolute debt by nearly $100 million and reduced leverage to under 3.0x. This absolute debt and leverage reduction positioned us to commence our share repurchase program during the fourth quarter of 2024, repurchasing $29 million of shares.”

Mr. Krueger added, “Looking ahead to 2025, we expect another year of increases in our EBITDA and Free Cash Flow after dividends. This positions us well for further debt reduction and increases in return of capital to shareholders.”

Share Repurchases

During the fourth quarter of 2024, Antero Midstream repurchased 1.9 million shares for $29 million. Antero Midstream had approximately $471 million of remaining capacity under its $500 million authorized share repurchase program as of December 31, 2024.

2025 Guidance

Antero Midstream is forecasting Net Income of $445 to $485 million and Adjusted Net Income (adjusted for amortization of customer relationships and effective tax rate impact) of $500 to $540 million. The Company is forecasting Adjusted EBITDA of $1.08 to $1.12 billion, which represents a 5% increase compared to 2024 at the midpoint. This Adjusted EBITDA growth is driven by low-single digit year-over-year throughput growth and inflation adjustments to Antero Midstream’s fixed fees. Antero Midstream expects to service 70 to 75 wells with its fresh water delivery system, with the wells having an average lateral length of approximately 13,200 feet. The Company’s 2025 guidance includes approximately $135 to $145 million of combined distributions from its interests in the processing and fractionation joint venture with MPLX, LP (the “Joint Venture”) and in Stonewall Gathering LLC (“Stonewall Joint Venture”).

Antero Midstream is forecasting a capital budget of $170 to $200 million. The midpoint of the 2025 capital budget includes approximately $85 million of investment in gathering and compression infrastructure for low pressure gathering connections and compression. Antero Midstream has budgeted an investment of $85 million for water infrastructure in 2025, primarily focused on the expansion to the southern Marcellus liquids-rich midstream corridor. This investment in wastewater blending and pipeline infrastructure creates one integrated water system in the Marcellus Shale, allowing for future capital efficient development across the entire liquids-rich midstream corridor. The Company is also budgeting $10 to $15 million of capital contributions to the Stonewall Joint Venture to increase its capacity.

Antero Midstream is forecasting Free Cash Flow before dividends of $690 to $730 million and Free Cash Flow after dividends of $250 to $300 million for 2025, assuming an annualized dividend of $0.90 per share. This represents a 10% increase in Free Cash Flow after dividends at the midpoint of guidance compared to 2024.

The following is a summary of Antero Midstream’s 2025 guidance ($ in millions, except per share amounts):

Non-GAAP Financial Measures and Definitions

Antero Midstream uses certain non-GAAP financial measures. Antero Midstream defines Adjusted Net Income as Net Income plus amortization of customer relationships, impairment of property and equipment, loss on early extinguishment of debt, and loss (gain) on asset sale, net of tax effect of reconciling items. Antero Midstream uses Adjusted Net Income to assess the operating performance of its assets. Antero Midstream defines Adjusted EBITDA as Net Income plus net interest expense, income tax expense, depreciation expense, amortization of customer relationships, loss (gain) on asset sale, accretion of asset retirement obligations, impairment of property and equipment, loss on early extinguishment of debt, loss on settlement of asset retirement obligations, and equity-based compensation expense, excluding equity in earnings of unconsolidated affiliates, plus distributions from unconsolidated affiliates.

Antero Midstream uses Adjusted EBITDA to assess:

Antero Midstream defines Free Cash Flow before dividends as Adjusted EBITDA less net interest expense and accrual-based capital expenditures. 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 (“Net Debt”). 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 cash provided by operating activities to Free Cash Flow before and after dividends for the years ended December 31, 2023 and 2024 as used in this release (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):
