Current report
Operating activities. Net cash provided by operating activities was $211 million and $199 million for the three months ended March 31, 2024 and 2025, respectively. This decrease between periods was primarily due to higher cash paid for interest due to the timing of the semi-annual payments on our Senior Notes and increased direct operating expenses, partially offset by higher gathering and processing and water handling revenues.

Asset Acquisition
Previous report
On May 1, 2024, we acquired certain Marcellus gas gathering and compression assets from Summit for $70 million in cash, before closing adjustments, with an effective date of April 1, 2024. This acquisition was funded with our operating cash flow. The acquired assets include 48 miles of high pressure gathering pipelines and two compressor stations with 100 MMcf/d of compression capacity. These assets were already interconnected to our low pressure and high pressure gas gathering systems at the time of acquisition and service Antero Resources’ production. Currently, we do not expect to make any significant capital investments related to the acquired assets. See Note 6—Property and Equipment to the unaudited condensed consolidated financial statements for more information.

Direct operating expenses. Direct operating expenses remained consistent at $162 million for the nine months ended September 30, 2023 and 2024. Gathering and processing direct operating expenses increased by 6%, from $73 million for the nine months ended September 30, 2023 to $77 million for the nine months ended September 30, 2024 primarily due to increased gathering and compression volumes between periods and our acquisition of two compressor stations and 48 miles of high pressure gathering lines during the second quarter of 2024. Water handling direct operating expenses decreased by 5%, from $89 million for the nine months ended September 30, 2023 to $85 million for the nine months ended September 30, 2024 primarily due to lower fresh water volumes and decreased wastewater handling costs between periods, partially offset by increased pipeline maintenance, repair and monitoring activities.

Previous report
Interest expense. Interest expense decreased by 5%, from $165 million for the nine months ended September 30, 2023 to $157 million for the nine months ended September 30, 2024 primarily due to lower Credit Facility borrowings between periods and lower interest expense on our Senior Notes due to the repurchase and redemption of the remaining $550 million principal amount of the 2026 Notes during the nine months ended September 30, 2024, partially offset by the issuance of $600 million principal amount of 2032 Notes during the nine months ended September 30, 2024.

Equity in earnings of unconsolidated affiliates. Equity in earnings of unconsolidated affiliates increased by 6%, from $78 million for the nine months ended September 30, 2023 to $83 million for the nine months ended September 30, 2024 primarily due to increased processing and fractionation volumes and higher processing and fractionation fees as a result ofannual CPI-based adjustments between periods.
Previous report

The increase in income tax expense between periods is primarily due to higher income before income taxes during the nine months ended September 30, 2024.
Previous report
Operating activities. Net cash provided by operating activities was $571 million and $611 million for the nine months ended September 30, 2023 and 2024, respectively. The increase in cash flows provided by operations between periods was primarily due to higher gathering and processing revenues and increased distributions from our equity method investments during the nine months ended September 30, 2024, partially offset by lower water handling revenues and changes in working capital between periods.
Reworded paragraphs (20)
Previous wording
On February 13, 2024, our Board authorized a share repurchase program that allows us to repurchase up to $500 million of shares of our outstanding common stock. The shares may be repurchased from time to time in open market transactions, through privately negotiated transactions or by other means in accordance with federal securities laws. The timing, as well as the number and value of shares repurchased under the program, will be determined by us at our discretion and will depend on a variety of factors, including the market price of our common stock, general market and economic conditions and applicable legal requirements. The exact number of shares to be repurchased by us is not guaranteed and the program may be suspended, modified or discontinued at any time without prior notice. The 1% U.S. federal excise tax on certain repurchases of stock by publicly traded U.S. corporations enacted as part of the Inflation Reduction Act of 2022 applies to our share repurchase program. During the three and nine months ended September 30, 2024, we did not repurchase any shares under this program.
Current wording
During the three months ended March 31, 2025, we repurchased approximately 2 million shares of our common stock through our share repurchase program for a total cost of $29 million. As of March 31, 2025, we have approximately $443 million of capacity remaining under our share repurchase program. The shares may be repurchased from time to time in open market transactions, through privately negotiated transactions or by other means in accordance with federal securities laws. The timing, as well as the number and value of shares repurchased under the program, will be determined by us at our discretion and will depend on a variety of factors, including the market price of our common stock, general market and economic conditions and applicable legal requirements. The exact number of shares to be repurchased by us is not guaranteed and the program may be suspended, modified or discontinued at any time without prior notice.

Benchmark prices for natural gas decreased significantly, while benchmark prices for oil remained consistent and benchmark prices for NGLs increased during the nine months ended September 30, 2024 as compared to the same period of 2023. While substantially all of our revenues are based on fixed-fee contracts that are not directly impacted by changes in commodity prices, commodity price changes do impact the revenues and cash flows of Antero Resources, and Antero Resources’ drilling and development plan does have a direct impact on our gathering, compression and water handling services, revenues and cash flows. In the current economic environment, we expect that commodity prices for some or all of the commodities produced by Antero Resources could remain volatile. However, due to Antero Resources’ improved liquidity and leverage position as compared to historical levels, we do not expect to experience significant variability in our throughput volumes resulting from volatile commodity prices.

The economy experienced elevated inflation levels as a result of global supply and demand imbalances, where global demand outpaced supplies beginning in 2021 and continuing through the third quarter of 2024. For example, the Consumer Price Index (“CPI”) for all urban consumers increased 3.7% from September 2022 to September 2023 and an additional 2.4% from September 2023 to September 2024 as compared to the Federal Reserve’s stated goal of 2%. In order to manage the inflation risk present in the United States’ economy, the Federal Reserve utilized monetary policy in the form of interest rate increases beginning in March 2022 in an effort to bring the inflation rate in line with its stated goal of 2% on a long-term basis. Between March 2022 and July 2023, the Federal Reserve increased the federal funds interest rate by 5.25%. During the three months ended September 30, 2024, inflation rates began to approach the Federal Reserve’s stated goal of 2%, and the Federal Reserve decreased the federal funds rate by 0.5% in September 2024. While inflationary pressures in the United States’ economy have begun to subside, we continue to be impacted by the increased federal funds interest rate. See “—Results of Operations” for additional information.

Previous wording
Depreciation expense. Depreciation expense increased by 6%, from $101 million for the nine months ended September 30, 2023 to $107 million for the nine months ended September 30, 2024. This increase was primarily due to $3 million related to assets placed in service, $2 million of higher expense related to our program to repurpose underutilized compressor units to expand existing or construct new compressor stations during the nine months ended September 30, 2024 and $1 million for our assets acquired during the second quarter of 2024.

Depreciation expense. Depreciation expense decreased by 12%, from $37 million for the three months ended March 31, 2024 to $33 million for the three months ended March 31, 2025. This decrease was primarily due to lower depreciation expense of $5 million related to our program to repurpose underutilized compressor units to expand existing or construct new compressor stations, partially offset by depreciation expense of $1 million related to assets placed in service between periods.
Previous wording
Interest expense. Interest expense decreased by 6%, from $55 million for the three months ended September 30, 2023 to $52 million for the three months ended September 30, 2024 primarily due to lower Credit Facility borrowings between periods and lower interest expense on our Senior Notes due to the repurchase and redemption of the $550 million principal amount of the 2026 Notes during the first and second quarters of 2024, partially offset by the issuance of $600 million principal amount of 2032 Notes during the first quarter of 2024.
Current wording
Interest expense. Interest expense decreased by 9%, from $53 million for the three months ended March 31, 2024 to $48 million for the three months ended March 31, 2025 primarily due to lower interest expense for our 2026 Senior Notes that were fully retired during the second quarter of 2024 and lower rates on our Credit Facility borrowings, partially offset by higher Credit Facility borrowings between periods.

Previous wording
Investing activities. Net cash flows used in investing activities was $130 million and $203 million for the nine months ended September 30, 2023 and 2024, respectively. The increase in cash flows used in investing activities between periods was primarily due to our acquisition of gathering and compression assets during the second quarter of 2024 of $70 million, before closing adjustments, and increased capital spending for our gathering and processing systems of $20 million as a result of increased compression station and high pressure line capital projects between periods, partially offset by decreased capital spending for our water handling systems of $16 million primarily as a result of fewer capital projects between periods.
Current wording
Investing activities. Net cash flows used in investing activities was $37 million and $32 million for the three months ended March 31, 2024 and 2025, respectively. The decrease in cash flows used in investing activities between periods was primarily due to lower capital spending and acquisitions related to our gathering systems and facilities of $8 million, partially offset by additional investment in Stonewall of $2 million and higher capital spending on our water handling systems of $1 million between periods.
Previous wording
Financing activities. Net cash used in financing activities was $441 million and $408 million for the nine months ended September 30, 2023 and 2024, respectively. The decrease in cash flows used in financing activities between periods was primarily due to the issuance of the 2032 Notes of $600 million and lower net repayments on our Credit Facility of $15 million, partially offset by our repurchases and redemption of the 2026 Notes of $561 million, deferred financing costs payments on our 2032 Senior Notes and New Credit Facility of $13 million and higher tax withholdings for the settlement of equity-based compensation awards of $6 million between periods.
Current wording
Financing activities. Net cash used in financing activities was $147 million and $167 million for the three months ended March 31, 2024 and 2025, respectively. The increase in cash flows used in financing activities between periods was primarily due to higher common stock repurchases of $29 million, payments of employee tax withholdings for the settlement of equity-based compensation awards of $18 million and dividends to common stockholders of $5 million between periods, partially offset by refinancing of our Credit Facility borrowings with the issuance of our 2032 Senior Notes during the first quarter of 2024.
