Antero Midstream Announces Third Quarter 2023 Financial and Operating Results

Denver, Colorado, October 25, 2023—Antero Midstream Corporation (NYSE: AM) (“Antero Midstream” or the “Company”) today announced its third quarter 2023 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 quarter ended September 30, 2023.

Third Quarter 2023 Highlights:

	·	Gathering and compression volumes increased by 13% and 17%, respectively, compared to the prior year quarter
	·	Net Income was $98 million, or $0.20 per diluted share, an 18% per share increase compared to the prior year quarter
	·	Adjusted Net Income was $111 million, or $0.23 per diluted share, a 15% per share increase compared to the prior year quarter (non-GAAP measure)
	·	Adjusted EBITDA was $251 million, a 12% increase compared to the prior year quarter and 3% sequentially (non-GAAP measure)
	·	Capital expenditures were $57 million
	·	Free Cash Flow before dividends was $138 million and Free Cash Flow after dividends was $30 million (non-GAAP measures)
	·	Leverage declined to 3.4x at September 30, 2023 (non-GAAP measure)

Full Year 2023 Guidance Update:

	·	Increasing Adjusted EBITDA by $10 million at the midpoint to a range of $970 to $990 million (non-GAAP measure)
	·	Increasing Free Cash Flow after dividends by $5 million at the midpoint to a range of $135 to $155 million (non-GAAP measures)

Paul Rady, Chairman and CEO said, “During the third quarter, Antero Midstream delivered double-digit year-over-year throughput growth that set company records. The combination of well outperformance, acceleration of wells serviced by the fresh water delivery system, and operational success have resulted in year-to-date results that have exceeded expectations. Our organic growth strategy, supplemented by high-visibility, accretive acquisitions over the last year, has resulted in increased scale at Antero Midstream while maintaining a strong balance sheet and liquidity position.”

Brendan Krueger, CFO of Antero Midstream, said “The third quarter marked the fifth consecutive quarter that Antero Midstream has generated Free Cash Flow after dividends. Our disciplined approach utilizing Free Cash Flow after dividends to reduce debt has resulted in over $100 million of absolute debt reduction year-to-date and leverage declining to 3.4x.”

Mr. Krueger further added, “Looking ahead to 2024, we expect this Free Cash Flow to continue to increase compared to 2023, resulting in further absolute debt reduction and declining leverage towards our 3.0x target. This positions Antero Midstream to evaluate further return of capital to our shareholders in 2024.”

For a discussion of the non-GAAP financial measures, including Adjusted EBITDA, Adjusted Net Income, Leverage, and Free Cash Flow before and after dividends please see “Non-GAAP Financial Measures.”

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 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 interest expense, net, income tax expense, depreciation expense, amortization of customer relationships, loss (gain) on asset sale, loss on settlement of asset retirement obligations, accretion 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:

	*	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 Free Cash Flow before dividends as Adjusted EBITDA less interest expense, net 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):

	Three Months Ended September 30,
	2022			2023
Capital expenditures (as reported on a cash basis)	$	57,120			45,286
Change in accrued capital costs		(19,952	)		11,985
Capital expenditures (accrual basis)	$	37,168			57,271

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.

The following table reconciles consolidated total debt to consolidated net debt, excluding debt premiums and issuance costs, (“Net Debt”) as used in this release (in thousands):

	September 30, 2023
Bank credit facility	$	676,400

5.75% senior notes due 2028		650,000
5.375% senior notes due 2029		750,000
Consolidated total debt	$	3,276,400
Cash and cash equivalents		—
Consolidated net debt	$	3,276,400

The following table reconciles Net Income to Adjusted EBITDA for the last twelve months as used in this release (in thousands):

	Twelve Months Ended September 30, 2023
Net Income	$	354,132
Interest expense, net		217,653
Income tax expense		130,118
Depreciation expense		134,755
Amortization of customer relationships		70,672
Accretion of asset retirement obligation		177
Equity-based compensation		28,803
Equity in earnings of unconsolidated affiliates		(101,576	)
Distributions from unconsolidated affiliates		124,890
Loss on settlement of asset retirement obligation		620
Loss on asset sale		6,027
Adjusted EBITDA	$	966,271

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 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):

	Twelve Months Ended December 31, 2023
	Low		High
Depreciation expense	$	135	$	145
Equity based compensation expense		25		35
Amortization of customer relationships		70		75
Distributions from unconsolidated affiliates		125		135
