HOUSTON, May 6, 2026 – APA Corporation (Nasdaq: APA) today announced its financial and operational results for the first quarter of 2026. APA reported net income attributable to common stock of $446 million, or $1.26 per share on a fully diluted basis. When adjusted for certain items that impact the comparability of results, APA’s first-quarter earnings totaled $489 million, or $1.38 per diluted share.

First-quarter summary

First-quarter reported production was 442,000 BOE per day and adjusted production, which excludes Egypt noncontrolling interest and tax barrels, was 363,000 BOE per day. T3U.S. oil production averaged 124,000 barrels per day, exceeding guidance set in February from continued efficiency gains and improved uptime in the Permian Basin. In Egypt, adjusted production averaged 71,000 BOE per day, reflecting production sharing contract (PSC) impacts associated with higher oil prices. Underlying gross oil production benefited from strong well performance. Gross gas production averaged 518 million cubic feet (MMCF) per day, in-line with guidance.

Upstream capital investment and lease operating expense (LOE) were below guidance. Adjusted EBITDAX was $1.6 billion, and free cash flow totaled $477 million.

Debt management and shareholder return

T4Through April 2026, APA repaid $634 million in near-term bond maturities. Combined with deleveraging actions in 2025, this is expected to reduce annual interest expense by more than $60 million in 2026. In addition, APA returned $88 million to shareholders through dividends in the first quarter. The company remains committed to its capital returns framework.

CEO commentary

“Our first-quarter results reflect consistent execution across the portfolio,” said John J. Christmann IV, APA’s chief executive officer. “We delivered strong operational performance, exceeded U.S. oil production guidance, and generated significant free cash flow while maintaining capital discipline. At the same time, we continue to structurally lower our cost base, strengthen the balance sheet, and advance our high-quality portfolio of development and exploration opportunities.”

Second-quarter and full-year update

G3For the second quarter, APA expects U.S. oil production of 121,000 barrels per day. G4T5In Egypt, gross gas production is expected to increase to 540 MMCF per day, supported by ongoing success in the gas-focused drilling program. G5Upstream capital investment is projected to be approximately $575 million.

For the full-year 2026, the company is G6raising its U.S. oil production outlook to 122,000 barrels per day, reflecting strong uptime and continued efficiency gains in the Permian Basin. The company also G7reaffirms its prior guidance range of 540 – 550 MMCF per day for Egypt gross gas production. G8G9T6APA’s upstream capital investment and LOE guidance both remain unchanged at approximately $2.1 billion and $1.5 billion, respectively.

About APA

APA Corporation owns consolidated subsidiaries that explore for and produce oil and natural gas in the United States, Egypt and the United Kingdom and that explore for oil and natural gas offshore Suriname and elsewhere. APA posts announcements, operational updates, investor information and press releases on its website, www.apacorp.com.

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.

Forward-looking statements

This news release contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements can be identified by words such as “anticipates,” “intends,” “plans,” “seeks,” “believes,” “continues,” “could,” “estimates,” “expects,” “goals,” “guidance,” “may,” “might,” “outlook,” “possibly,” “potential,” “projects,” “prospects,” “should,” “upside,” “will,” “would,” and similar references to future periods, but the absence of these words does not mean that a statement is not forward-looking. These statements include, but are not limited to, statements about future plans, expectations, and objectives for operations, including statements about our capital plans, drilling plans, production expectations, asset sales, monetizations, and interest and other cost savings.

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. See “Risk Factors” in APA’s Form 10-K for the year ended December 31, 2025, and in our quarterly reports on Form 10-Q for a discussion of risk factors that affect our business. Any forward-looking statement made in this news release speaks only as of the date on which it is made. Factors or events that could cause our actual results to differ may emerge from time to time, and it is not possible for us to predict all of them.

APA and its subsidiaries undertake no obligation to publicly update any forward-looking statement, whether as a result of new information, future development or otherwise, except as may be required by law.

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 APA’s Annual Report on Form 10-K for the fiscal year ended Dec. 31, 2025, available from APA at www.apacorp.com or by writing APA at: 2000 W. Sam Houston Pkwy S, Suite. 200, Houston, TX 77042 (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.

NON-GAAP FINANCIAL MEASURES

(In millions)

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 property and leasehold acquisitions, asset retirement additions and revisions, capitalized interest, and certain exploration expenses. 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.

NON-GAAP FINANCIAL MEASURES

(In millions)

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.

STATEMENT OF CONSOLIDATED OPERATIONS

(In millions, except per share data)

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.
