Antero Midstream Announces Second Quarter 2024 Financial and Operating Results

Denver, Colorado, July 31, 2024—Antero Midstream Corporation (NYSE: AM) (“Antero Midstream” or the “Company”) today announced its second quarter 2024 financial and operating results. The relevant unaudited condensed consolidated financial statements are included in Antero Midstream’s Quarterly Report on Form 10-Q for the three months ended June 30, 2024.

Second Quarter 2024 Highlights:

Paul Rady, Chairman and CEO said, “During the quarter, Antero Midstream closed on a highly strategic bolt-on acquisition, increasing throughput volumes from our primary investment grade customer, Antero Resources. This acquisition complements our organic just-in-time business model that generates consistent Free Cash Flow after dividends, which increased 41% year-over-year.”

Brendan Krueger, CFO of Antero Midstream, said “During 2024, Antero Midstream improved its balance sheet through the successful refinancing of its highest coupon senior notes and the extension of its credit facility to 2029. Importantly, over the last year, we have reduced our net debt by $120 million and our leverage has declined from 3.5x to 3.1x. This balance sheet improvement is evidenced by our upgrade from S&P and highlights our consistent Free Cash Flow generation and the accretive nature of the recent bolt-on acquisition.”

Second Quarter 2024 Financial Results

Antero Midstream’s second quarter financial and operating results include two months of contribution from the compression and high pressure gathering assets located in Antero Midstream’s core West Virginia Marcellus Shale position acquired from Summit Midstream Partners, LP.

Low pressure gathering volumes for the second quarter of 2024 averaged 3,258 MMcf/d, a 1% decrease as compared to the prior year quarter. Compression volumes for the second quarter of 2024 averaged 3,246 MMcf/d, in line with the prior year quarter. High pressure gathering volumes averaged 2,994 MMcf/d, a 2% increase compared to the prior year quarter. Fresh water delivery volumes averaged 81 MBbl/d during the quarter, a 23% decrease compared to the second quarter of 2023. The reduction in fresh water delivery volumes was driven by the previously announced reduction by Antero Resources to one completion crew in early 2024, resulting in fewer completion stages in the second quarter.

Gross processing volumes from the processing and fractionation joint venture with MPLX, LP (the “Joint Venture”) averaged 1,588 MMcf/d for the second quarter of 2024, a 1% decrease compared to the prior year quarter. Joint Venture processing capacity was 99% utilized during the quarter based on nameplate processing capacity of 1.6 Bcf/d. Gross Joint Venture fractionation volumes averaged 40 MBbl/d, a 3% increase compared to the prior year quarter. Joint Venture fractionation capacity was 100% utilized during the quarter based on nameplate fractionation capacity of 40 MBbl/d.

For the three months ended June 30, 2024, revenues were $270 million, comprised of $229 million from the Gathering and Processing segment and $59 million from the Water Handling segment, net of $18 million of amortization of customer relationships. Water Handling revenues include $27 million from wastewater handling and high rate water transfer services.

Direct operating expenses for the Gathering and Processing and Water Handling segments were $26 million and $30 million, respectively, for a total of $56 million. Water Handling operating expenses include $24 million from wastewater handling and high rate water transfer services. General and administrative expenses excluding equity-based compensation were $10 million during the second quarter of 2024. Total operating expenses during the second quarter of 2024 included $12 million of equity-based compensation expense and $38 million of depreciation.

Net Income was $86 million, or $0.18 per diluted share, in line with the prior year quarter. Net Income adjusted for amortization of customer relationships, loss on early extinguishment of debt, loss on settlement of asset retirement obligation and loss on asset sale, net of tax effects of reconciling items, or Adjusted Net Income, was $110 million. Adjusted Net Income was $0.23 per diluted share, a 5% per share increase compared to the prior year quarter.

The following table reconciles Net Income to Adjusted Net Income (in thousands):

(1) The statutory tax rates for the three months ended June 30, 2023 and 2024 were 25.7% and 25.8%, respectively.

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, loss on early extinguishment of debt, loss on settlement of asset retirement obligations and loss 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 on early extinguishment of debt, loss on asset sale, accretion of asset retirement obligations, impairment of property and equipment, 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 (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.

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. 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.
