Antero Resources Announces First Quarter 2026 Financial and Operating Results

Denver, Colorado, April 29, 2026—Antero Resources Corporation (NYSE: AR) (“Antero Resources,” “Antero,” or the “Company”) today announced its first quarter 2026 financial and operating results. The relevant consolidated financial statements are included in Antero Resources’ Quarterly Report on Form 10-Q for the quarter ended March 31, 2026.

Highlights:

Michael Kennedy, CEO and President of Antero Resources commented, “During the first quarter we achieved record production, which was 13% above the year ago period. This production growth drove one of the highest quarterly EBITDAX and Free Cash Flow results in company history. These results reflect a tremendous performance from our operations team which navigated the harsh conditions of Winter Storm Fern without having to shut-in any volumes. This enabled Antero to deliver critical natural gas to the various regions that needed it most, a truly remarkable achievement by our people in the field.”

Mr. Kennedy continued, “Looking ahead, the recent geopolitical events have highlighted the advantages of Antero’s corporate strategy. We are the largest producer exporter of NGLs in the U.S., selling the majority of our NGL barrels into international markets. We expect recent global supply outages and disruptions to lead to increasing risk premiums for U.S. NGL barrels both in the near term and in the years ahead. At the same time, we have the highest LNG exposure among Appalachian producers, selling 2.3 Bcf/d of production to sales points along the LNG fairway. We are seeing growing interest from global NGL and LNG buyers that are looking to increase exposure to U.S. supply. This prioritization toward U.S. supply supports higher export utilization and more attractive price premiums at our sales points along the coasts. These attributes uniquely position us to benefit from today’s rising global demand for U.S. energy.”

Brendan Krueger, CFO of Antero Resources said, “During the first quarter we closed on the HG acquisition and began integration of the new asset. The impressive operational and financial achievements mentioned above led to realizations for natural gas, NGLs and ethane all coming in ahead of expectations during the quarter. This allowed us to reduce debt related to the HG acquisition ahead of our previously communicated targets. Importantly, as a result of the transactions, we expect our net production to increase by approximately 700 MMcfe/d on an annual basis. Additionally, the HG acquisition added 385,000 net acres and 400 drilling locations, while only increasing our Net Debt by $1.5 billion from the year-end 2025 level.”

For a discussion of the non-GAAP financial measures including Adjusted Net Income, Adjusted EBITDAX, Adjusted Free Cash Flow and Net Debt please see “Non-GAAP Financial Measures.”

Cash Cost Reduction

Antero expects cash production expense for the remainder of 2026 to be $2.20 to $2.30 per Mcfe. This reduced range reflects a $0.25 per Mcfe, or 10% reduction from the full-year average in 2025 and a $0.39 per Mcfe, or 15% reduction from the first quarter of 2026. Inclusive of G&A and net marketing expense the total cost reduction is expected to be $0.30 per Mcfe. The production and development of the HG assets are expected to result in cash production expenses remaining in that range going forward, assuming current natural gas strip pricing.

Second Quarter and Full-Year 2026 Guidance Update

Antero expects second quarter production to average 4.1 Bcfe/d, a 6% increase from the first quarter of 2026, driven by a full quarter of production from the HG acquisition. The second half of 2026 is expected to average approximately 4.2 Bcfe/d. This results in a full year average of approximately 4.1 Bcfe/d, unchanged from prior guidance. This annual guidance reflects approximately 20% growth year-over-year. The Company is increasing its ethane realized price premium to Mont Belvieu to $2.00 to $3.00 per barrel, reflecting a $1.00 per barrel increase at the midpoint from the prior guidance range. The Company is reducing its cash production expense guidance to a range of $2.25 to $2.35 per Mcfe, a $0.10 per Mcfe reduction at the midpoint. The lower cash production expense is due primarily to the impact of the integration of the lower production costs associated with the HG assets.

Note: Any 2026 guidance items not discussed in this release are unchanged from previously stated guidance.

First Quarter 2026 Financial Results

Net daily natural gas equivalent production in the first quarter averaged 3.9 Bcfe/d, including 206 MBbl/d of liquids. Antero’s average realized natural gas price before hedges was $5.57 per Mcf, a $0.53 per Mcf premium to the benchmark Henry Hub index price. Antero’s average realized C3+ NGL price before hedges was $37.83 per barrel, representing a $0.94 per barrel premium to the benchmark index price.

The following table details average net production and average realized prices for the three months ended March 31, 2026:

All-in cash expense, which includes lease operating, gathering, compression, processing and transportation and production and ad valorem taxes was $2.64 per Mcfe in the first quarter, as compared to $2.56 per Mcfe during the first quarter of 2025. The increase compared to the prior year was due to higher fuel costs related to higher natural gas prices during the quarter. Net marketing expense was $0.06 per Mcfe during the first quarter of 2026, unchanged from the first quarter of 2025.

Operating Results

Antero placed 20 Marcellus wells to sales during the first quarter with an average lateral length of 11,652 feet. Thirteen of these wells have been on line for approximately 60 days with an average rate per well of 25 MMcfe/d, including 1,457 Bbl/d of liquids per well assuming 25% ethane recovery. In addition, Antero had a number of notable company operating achievements, including:

First Quarter 2026 Capital Investment

Antero’s drilling and completion capital expenditures for the three months ended March 31, 2026 were $223 million. In addition to capital invested in drilling and completion activities, the Company invested $25 million in land during the first quarter. Through this investment, Antero added approximately 5,400 net acres, representing 24 incremental drilling locations at an average cost of approximately $900,000 per location.

Non-GAAP Financial Measures

Adjusted Net Income

Adjusted Net Income as set forth in this release represents net income, adjusted for certain items. Antero believes that Adjusted Net Income is useful to investors in evaluating operational trends of the Company and its performance relative to other oil and gas producing companies. Adjusted Net Income is not a measure of financial performance under GAAP and should not be considered in isolation or as a substitute for net income as an indicator of financial performance. The GAAP measure most directly comparable to Adjusted Net Income is net income. The following table reconciles net income to Adjusted Net Income (in thousands):

Net Debt

Net Debt is calculated as total long-term debt less cash and cash equivalents. Management uses Net Debt to evaluate the Company’s financial position, including its ability to service its debt obligations.

The following table reconciles consolidated total long-term debt to Net Debt as used in this release (in thousands):

Adjusted Free Cash Flow

Adjusted Free Cash Flow is a measure of financial performance not calculated under GAAP and should not be considered in isolation or as a substitute for cash flow from operating, investing, or financing activities, as an indicator of cash flow or as a measure of liquidity. The Company defines Adjusted Free Cash Flow as net cash provided by operating activities, less capital expenditures, which includes additions to unproved properties, drilling and completion costs and additions to other property and equipment, less distributions to non-controlling interests in Martica, plus transaction expenses.

The Company has not provided projected net cash provided by operating activities or a reconciliation of Adjusted Free Cash Flow to projected net cash provided by operating activities, the most comparable financial measure calculated in accordance with GAAP. The Company is unable to project net cash provided by operating activities for any future period because this metric includes the impact of changes in operating assets and liabilities related to the timing of cash receipts and disbursements that may not relate to the period in which the operating activities occurred. The Company is unable to project these timing differences with any reasonable degree of accuracy without unreasonable efforts.

Adjusted Free Cash Flow is a useful indicator of the Company’s ability to internally fund its activities, service or incur additional debt and estimate our ability to return capital to shareholders. There are significant limitations to using Adjusted Free Cash Flow as a measure of performance, including the inability to analyze the effect of certain recurring and non-recurring items that materially affect the Company’s net income, the lack of comparability of results of operations of different companies and the different methods of calculating Adjusted Free Cash Flow reported by different companies. Adjusted Free Cash Flow does not represent funds available for discretionary use because those funds may be required for debt service, land acquisitions and lease renewals, other capital expenditures, working capital, income taxes, exploration expenses, and other commitments and obligations.

Adjusted EBITDAX

Adjusted EBITDAX is a non-GAAP financial measure that we define as net income, adjusted for certain items detailed below.

Adjusted EBITDAX as used and defined by us, may not be comparable to similarly titled measures employed by other companies and is not a measure of performance calculated in accordance with GAAP. Adjusted EBITDAX should not be considered in isolation or as a substitute for operating income or loss, net income or loss, cash flows provided by operating, investing, and financing activities, or other income or cash flow statement data prepared in accordance with GAAP. Adjusted EBITDAX provides no information regarding our capital structure, borrowings, interest costs, capital expenditures, working capital movement, or tax position. Adjusted EBITDAX does not represent funds available for discretionary use because those funds may be required for debt service, capital expenditures, working capital, income taxes, exploration expenses, and other commitments and obligations. However, our management team believes Adjusted EBITDAX is useful to an investor in evaluating our financial performance because this measure:

There are significant limitations to using Adjusted EBITDAX as a measure of performance, including the inability to analyze the effects of certain recurring and non-recurring items that materially affect our net income or loss, the lack of comparability of results of operations of different companies, and the different methods of calculating Adjusted EBITDAX reported by different companies.

The GAAP measures most directly comparable to Adjusted EBITDAX are net income and net cash provided by operating activities. The following table represents a reconciliation of Antero’s net income, including noncontrolling interest, to Adjusted EBITDAX and a reconciliation of Antero’s Adjusted EBITDAX to net cash provided by operating activities per our condensed consolidated statements of cash flows, in each case, for the three months ended March 31, 2025 and 2026 (in thousands). Adjusted EBITDAX also excludes the noncontrolling interests in Martica, and these adjustments are disclosed in the table below as Martica related adjustments.

Drilling and Completion Capital Expenditures

For a reconciliation between cash paid for drilling and completion capital expenditures and drilling and completion accrued capital expenditures during the period, please see the capital expenditures section below (in thousands):

Notwithstanding their use for comparative purposes, the Company’s non-GAAP financial measures may not be comparable to similarly titled measures employed by other companies.
