Antero Resources Announces Third Quarter 2023 Financial and Operating Results and Increased Production Guidance

Denver, Colorado, October 25, 2023—Antero Resources Corporation (NYSE: AR) (“Antero Resources,” “Antero,” or the “Company”) today announced its third quarter 2023 financial and operating results. The relevant consolidated financial statements are included in Antero Resources’ Quarterly Report on Form 10-Q for the quarter ended September 30, 2023.

Third Quarter 2023 Highlights:

2023 Guidance Updates:

Paul Rady, Chairman, CEO and President of Antero Resources commented, “Our third quarter results continue to benefit from the operating momentum that we have built throughout this year. During the first nine months of 2023 both our drilling and completion teams set numerous Company records. This operational excellence combined with stellar well performance has led to quarterly production volumes above expectations. As a result, we are raising our full year production guidance for the second consecutive quarter, while maintaining the same initial capital budget. We now expect production volumes to increase by approximately 225 MMcfe/d, or 7%, from the 2022 exit rate to the 2023 exit rate.”

Mr. Rady continued, “On the macro front, we see natural gas storage levels normalizing on the back of record Natural Gas Power Burn (natural gas fired electrical generation), strong LNG exports and U.S. natural gas exported through pipelines to Mexico. At the same time, we anticipate that U.S. production growth will be limited in the coming months following the dramatic decrease in drilling rigs. We believe this strong fundamental backdrop will support and strengthen the forward natural gas curve. Further, as we move closer to the startup of additional LNG export capacity over the next 12 months, we are seeing increasing premiums at our delivery points within the LNG corridor relative to NYMEX. We are uniquely positioned to benefit from increasing NYMEX prices with approximately 75% of our natural gas being sold at Antero’s premium delivery points in the LNG corridor.”

Michael Kennedy, CFO of Antero Resources said, “Based entirely on the capital efficiency gains achieved this year, we continue to expect 2024 capital requirements to be materially below our 2023 capital guidance. This capital program will target maintaining our increased 2023 production guidance. This reduced maintenance capital combined with a higher natural gas and NGL price strip, is projected to generate substantial Free Cash Flow in 2024 that we will use to pay down debt further and continue to return capital to our shareholders.”

2023 Guidance Update

Antero is increasing its full year 2023 production guidance to 3.39 to 3.41 Bcfe/d, an increase at the midpoint of approximately 25 MMcfe/d. The higher than expected volumes are driven by strong well performance and capital efficiency gains.

Antero is decreasing the high end of its cash production expense guidance by $0.05 per Mcfe to a range of $2.35 to $2.40 per Mcfe reflecting lower fuel costs and lower production and ad valorem taxes. Antero is also decreasing its natural gas realized price guidance to flat to NYMEX Henry Hub. This decrease is due to increased exposure to the Columbia Gas Appalachia Hub during the third quarter driven by maintenance at the Cove Point LNG Terminal as well as longer maintenance on a Gulf Coast directed pipeline during the quarter. Antero is reducing its net marketing expense guidance by $0.02 per Mcfe to a range of $0.05 to $0.07 per Mcfe due to higher than expected production lowering unutilized firm transportation expense.

Note: Any 2023 guidance items not discussed in this release are unchanged from previously stated guidance.

Free Cash Flow

During the third quarter of 2023, Free Cash Flow before Changes in Working Capital was ($23) million.

Third Quarter 2023 Financial Results

Net daily natural gas equivalent production in the third quarter averaged 3.5 Bcfe/d, including 202 MBbl/d of liquids, an increase of 9% from the third quarter of 2022. As a result of Antero’s focus on its liquids-rich Marcellus acreage, liquids volumes increased 18%, while natural gas volumes increased 4%, each compared to the year ago period.

Antero’s average realized natural gas price before hedging was $2.48 per Mcf, a $0.07 per Mcf discount to the average first-of-month (“FOM”) NYMEX Henry Hub price. The wider discount to NYMEX was due to higher volumes being sold into the Columbia Gas Appalachia Hub as a result of maintenance at the Cove Point LNG Terminal and the Tennessee 500 Leg Pipeline. During the quarter, Antero sold approximately 15% of its volume into the Columbia Gas Appalachia Hub, 5% above levels during the first six months of the year.

The following table details average net production and average realized prices for the three months ended September 30, 2023:

Antero’s average realized C3+ NGL price was $36.81 per barrel. Antero shipped 52% of its total C3+ NGL net production on Mariner East 2 (“ME2”) for export and realized a $0.06 per gallon premium to Mont Belvieu pricing on these volumes at Marcus Hook, PA. Antero sold the remaining 48% of C3+ NGL net production at an $0.07 per gallon discount to Mont Belvieu pricing at Hopedale, OH. The resulting blended price on 119 MBbl/d of net C3+ NGL production was a $0.01 per gallon premium to Mont Belvieu pricing.

All-in cash expense, which includes lease operating, gathering, compression, processing, and transportation, production and ad valorem taxes was $2.31 per Mcfe in the third quarter, a 19% decrease compared to $2.84 per Mcfe average during the third quarter of 2022. The decrease was due to lower production tax and transportation expense due to lower fuel costs as a result of lower commodity prices. Net marketing expense was $0.05 per Mcfe in the third quarter, a decrease from $0.09 per Mcfe during the third quarter of 2022. The decrease in net marketing expense was due to higher than expected production lowering unutilized firm transportation expense.

Third Quarter 2023 Operating Results

Antero placed 20 horizontal Marcellus wells to sales during the third quarter with an average lateral length of 14,400 feet. Of the wells placed to sales, 14 of these wells have been on line for at least 60 days. The average 60-day rate per well was 24 MMcfe/d with approximately 1,150 Bbl/d of liquids per well assuming 25% ethane recovery. The remaining six wells were completed in mid-September and had an average lateral length of approximately 18,400 feet.

Marcellus highlights include:

In the Utica, Antero has two pads consisting of seven total wells scheduled to be turned in line during the fourth quarter. These wells are located in the highly rich 1300 BTU window of the Utica, with the natural gas volumes being sold into the premium Chicago market this winter. Antero also set numerous company drilling and completion records for the Utica during the third quarter.

Utica records include:

Third Quarter 2023 Capital Investment

Antero’s accrued drilling and completion capital expenditures for the three months ended September 30, 2023, were $231 million. Through the first nine months of 2023, the Company has completed approximately 80% of its 2023 expected completion stages.

In addition to capital invested in drilling and completion activities, the Company invested $27 million in land during the third quarter. During the quarter, Antero added approximately 4,000 net acres, representing over 14 incremental drilling locations. Through the first nine months of 2023, Antero has added approximately 26,000 net acres representing 93 incremental drilling locations at an average cost of approximately $1 million per location. Antero’s organic leasing efforts focus on acreage in close proximity to its current development plan. These incremental locations more than offset Antero’s maintenance capital plan that requires an average of 60 to 65 wells per year. In addition, these efforts allow Antero to increase the average lateral length in its development program, which is expected to average 14,500 feet for wells drilled in 2023, or 7% longer than the 2022 average of 13,600 feet. The Company believes this organic leasing program is the most cost effective approach to lengthening its core inventory position.

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):

Free Cash Flow

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 Free Cash Flow as net cash provided by operating activities, less net cash used in investing activities, which includes drilling and completion capital and leasehold capital, plus payments for early contract termination or derivative monetization, less proceeds from asset sales or derivative monetization and less distributions to non-controlling interests in Martica.

The Company has not provided projected net cash provided by operating activities or a reconciliation of 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.

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 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 Free Cash Flow reported by different companies. 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 (loss), 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 (loss) and net cash provided by operating activities. The following table represents a reconciliation of Antero’s net income (loss), including noncontrolling interest, to Adjusted EBITDAX and a reconciliation of Antero’s Adjusted EBITDAX to net cash provided by operating activities per our consolidated statements of cash flows, in each case, for the three months ended September 30, 2022 and 2023. 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.
