APA Corporation Announces Second-Quarter 2021

Financial and Operational Results

Key Takeaways

HOUSTON, Aug. 4, 2021 – APA Corporation (Nasdaq: APA) today announced its financial and operational results for the second-quarter 2021.

APA reported net income attributable to common stock of $316 million, or $0.82 per diluted share. When adjusted for items that impact the comparability of results, APA’s second-quarter earnings were $266 million, or $0.70 per diluted share. Net cash provided by operating activities was $969 million, and adjusted EBITDAX was $1.01 billion.

“A combination of strong well performance in the U.S., continued capital and cost discipline, and a favorable price environment enabled free cash flow generation of nearly $400 million during the quarter,” said John J. Christmann IV, APA’s CEO and president. “I am also very pleased with the progress we have made on our ESG initiatives, Production Sharing Contract modernization in Egypt and appraisal drilling in Suriname.”

The company is advancing key ESG initiatives and announced that it will achieve its goal of eliminating routine flaring onshore in the U.S. in the third quarter of this year. The focus on that goal has also helped drive down flaring intensity, which is tracking below the company’s goal of less than 1% for the year.

In May, the company reached an agreement in principle to modernize Production Sharing Contract terms in Egypt. The agreement has been finalized and signed by the Egyptian Ministry of Petroleum and Mineral Resources and the Egyptian General Petroleum Corporation and is proceeding through the next stages of the approval process.

In Suriname, APA and TotalEnergies announced last week a successful appraisal well in the Sapakara area, which encountered approximately 30 meters (98 feet) of net black oil pay in a single, high-quality zone of the Campano-Maastrichtian reservoir. This moves the JV closer to its goal of sanctioning the first commercial oil development in Block 58. Upon completion of drilling operations at Sapakara, the Maersk Valiant will move to the Bonboni exploration prospect approximately 45 kilometers to the north.

Second-Quarter Summary

Second-quarter reported production was 395,000 BOE per day, and adjusted production, which excludes Egypt noncontrolling interest and tax barrels, was 342,000 BOE per day. U.S. production of 242,000 BOE per day benefitted from strong well performance throughout the company’s Permian Basin DUC completion program. This more than offset slightly lower international adjusted volumes of 100,000 BOE per day, which were impacted by lower cost recovery barrels in Egypt due to higher oil prices and extended operational downtime in the North Sea. APA’s second-quarter upstream capital investment was $257 million, which was below guidance primarily due to timing.

APA, excluding Altus Midstream, had total debt of $8.0 billion, cash and cash equivalents of $1.2 billion, and $3.2 billion available capacity under its undrawn revolving credit facility at the end of the quarter.

Looking Ahead

“APA is capable of delivering strong and sustainable free cash flow for many years to come. At current strip prices, we expect to generate approximately $1.7 billion of free cash flow this year to support our debt reduction goals,” Christmann concluded.

Additional Information

Additional information follows, including reconciliations of adjusted earnings, adjusted EBITDAX, upstream capital investment, net debt, cash flows from operations before changes in operating assets and liabilities and free cash flow (non-GAAP financial measures) to GAAP measures and information regarding adjusted production. APA’s quarterly supplement is available at http://www.apacorp.com/financialdata.

Non-GAAP Financial Measures

APA’s financial information includes information prepared in conformity with generally accepted accounting principles (GAAP) as well as non-GAAP financial information. It is management’s intent to provide non-GAAP financial information to enhance understanding of our consolidated financial information as prepared in accordance with GAAP. Adjusted earnings, adjusted EBITDAX, upstream capital investment, net debt, cash flows from operations before changes in operating assets and liabilities and free cash flow are non-GAAP measures. This non-GAAP information should be considered by the reader in addition to, but not instead of, the financial statements prepared in accordance with GAAP. Each non-GAAP financial measure is presented along with the corresponding GAAP measure so as not to imply that more emphasis should be placed on the non-GAAP measure.

While forward-looking statements are based on assumptions and analyses made by us that we believe to be reasonable under the circumstances, whether actual results and developments will meet our expectations and predictions depend on a number of risks and uncertainties which could cause our actual results, performance, and financial condition to differ materially from our expectations.

Cautionary Note to Investors

The United States Securities and Exchange Commission permits oil and gas companies, in their filings with the SEC, to disclose only proved, probable, and possible reserves that meet the SEC’s definitions for such terms. APA may use certain terms in this news release, such as “resources,” “potential resources,” “resource potential,” “estimated net reserves,” “recoverable reserves,” and other similar terms that the SEC guidelines strictly prohibit APA from including in filings with the SEC. Such terms do not take into account the certainty of resource recovery, which is contingent on exploration success, technical improvements in drilling access, commerciality and other factors, and are therefore not indicative of expected future resource recovery and should not be relied upon. Investors are urged to consider carefully the disclosure in Apache Corporation’s Annual Report on Form 10-K for the fiscal year ended Dec. 31, 2020 available from APA at www.apacorp.com or by writing APA at: 2000 Post Oak Blvd., Suite 100, Houston, TX 77056 (Attn: Corporate Secretary). You can also obtain this report from the SEC by calling 1-800-SEC-0330 or from the SEC’s website at www.sec.gov.

ADJUSTED PRODUCTION INFORMATION

Adjusted production excludes certain items that management believes affect the comparability of operating results for the periods presented. Adjusted production excludes production attributable to 1) noncontrolling interest in Egypt and 2) Egypt tax barrels. Management uses adjusted production to evaluate the company’s operational trends and performance and believes it is useful to investors and other third parties.

NON-GAAP FINANCIAL MEASURES

(In millions, except per share data)

Reconciliation of Costs incurred to Upstream capital investment

Management believes the presentation of upstream capital investments is useful for investors to assess APA’s expenditures related to our upstream capital activity. We define capital investments as costs incurred for oil and gas activities, adjusted to exclude asset retirement obligation revisions and liabilities incurred, capitalized interest, and certain exploration expenses, while including amounts paid during the period for abandonment and decommissioning expenditures. Upstream capital expenditures attributable to a one-third noncontrolling interest in Egypt are also excluded. Management believes this provides a more accurate reflection of APA’s cash expenditures related to upstream capital activity and is consistent with how we plan our capital budget.

Reconciliation of Net cash provided by operating activities to Cash flows from operations before changes in operating assets and liabilities and Free cash flow

Cash flows from operations before changes in operating assets and liabilities and free cash flow are non-GAAP financial measures. APA uses these measures internally and provides this information because management believes it is useful in evaluating the company’s ability to generate cash to internally fund exploration and development activities, fund dividend programs, and service debt, as well as to compare our results from period to period. We believe these measures are also used by research analysts and investors to value and compare oil and gas exploration and production companies and are frequently included in published research reports when providing investment recommendations. Cash flows from operations before changes in operating assets and liabilities and free cash flow are additional measures of liquidity but are not measures of financial performance under GAAP and should not be considered as an alternative to cash flows from operating, investing, or financing activities. Additionally, this presentation of free cash flow may not be comparable to similar measures presented by other companies in our industry.

Reconciliation of Net cash provided by operating activities to Adjusted EBITDAX

Management believes EBITDAX, or earnings before income tax expense, interest expense, depreciation, amortization and exploration expense is a widely accepted financial indicator, and useful for investors, to assess a company’s ability to incur and service debt, fund capital expenditures, and make distributions to shareholders. We define adjusted EBITDAX, a non-GAAP financial measure, as EBITDAX adjusted for certain items presented in the accompanying reconciliation. Management uses adjusted EBITDAX to evaluate our ability to fund our capital expenditures, debt services and other operational requirements and to compare our results from period to period by eliminating the impact of certain items that management does not consider to be representative of the Company’s on-going operations. Management also believes adjusted EBITDAX facilitates investors and analysts in evaluating and comparing EBITDAX from period to period by eliminating differences caused by the existence and timing of certain operating expenses that would not otherwise be apparent on a GAAP basis. However, our presentation of adjusted EBITDAX may not be comparable to similar measures of other companies in our industry.

NON-GAAP FINANCIAL MEASURES

(In millions)

Reconciliation of debt to net debt

Net debt, or outstanding debt obligations less cash and cash equivalents, is a non-GAAP financial measure. Management uses net debt as a measure of the Company’s outstanding debt obligations that would not be readily satisfied by its cash and cash equivalents on hand. The Altus Midstream LP credit facility is unsecured and is not guaranteed by APA or any of APA’s other subsidiaries.

Reconciliation of Income attributable to common stock to Adjusted earnings

Our presentation of adjusted earnings and adjusted earnings per share are non-GAAP measures because they exclude the effect of certain items included in Income Attributable to Common Stock. Management believes that adjusted earnings and adjusted earnings per share provides relevant and useful information, which is widely used by analysts, investors and competitors in our industry as well as by our management in assessing the Company’s operational trends and comparability of results to our peers.

Management uses adjusted earnings and adjusted earnings per share to evaluate our operating and financial performance because it eliminates the impact of certain items that management does not consider to be representative of the Company’s on-going business operations. As a performance measure, adjusted earnings may be useful to investors in facilitating comparisons to others in the Company’s industry because certain items can vary substantially in the oil and gas industry from company to company depending upon accounting methods, book value of assets, capital structure and asset sales and other divestitures, among other factors. Management believes excluding these items facilitates investors and analysts in evaluating and comparing the underlying operating and financial performance of our business from period to period by eliminating differences caused by the existence and timing of certain expense and income items that would not otherwise be apparent on a GAAP basis. However, our presentation of adjusted earnings and adjusted earnings per share may not be comparable to similar measures of other companies in our industry.
