HOUSTON, Feb. 26, 2025 – APA Corporation (Nasdaq: APA) today announced its financial and operational results for the fourth quarter and full-year 2024.

In the fourth quarter, APA reported net income attributable to common stock of $354 million or $0.96 per diluted common share. When adjusting for

Fourth-quarter reported production was 488,000 BOE per day. Adjusted production, excluding Egypt noncontrolling interest and tax barrels, was 418,000 BOE

per day.

For the full-year 2024, APA reported net income attributable to common stock of $804 million, or $2.27 per diluted common share. On an

adjusted basis, APA’s 2024 earnings totaled $1.3 billion or $3.77 per diluted common share. Reported full-year production was 455,000 BOE per day; adjusted production was 385,000 BOE per day. Full-year net cash provided by operating

APA CORPORATION ANNOUNCES FOURTH-QUARTER AND FULL-YEAR 2024 FINANCIAL AND OPERATIONAL

RESULTS

During the year, APA generated $841 million of free cash flow, repurchased $246 million of common

stock, and paid $353 million in dividends. The company ended the year with debt of $6 billion and cash of $625 million, an increase in net debt of only $300 million from the end of 2023, despite adding over $2 billion of

debt with the Callon acquisition.

CEO Commentary

“Over the last several years, APA has been strategically reshaped in numerous ways. We have enhanced the quality and sustainability of the portfolio in

our core areas of the Permian Basin and the Western Desert of Egypt, while also building optionality through a differentiated exploration strategy,” said John J. Christmann IV, APA’s chief executive officer.

“In 2024, we continued this momentum with the acquisition of Callon, the final investment decision for the GranMorgu project in Suriname, and the new gas

agreement in Egypt. These actions have further strengthened our portfolio and improved the quality of our investment opportunities, positioning APA for long-term growth and success. We have assembled a large-scale unconventional position in the

Permian Basin, surpassing many of our pure-play peers. In addition, we made further progress on strengthening our balance sheet, achieving investment-grade status with all three rating agencies.”

2025 Capital Budget and Outlook

invest $2.5 to $2.6 billion in upstream oil and gas capital. This includes $200 million toward progressing the GranMorgu project in Suriname and $100 million for exploration activities, predominantly in Alaska.

Total company adjusted production is expected to be relatively flat year-over-year at around 396,000 BOE per day. G6U.S. oil volumes should stay relatively

consistent at 125,000 to 127,000 barrels of oil per day, and gas volumes will benefit from no price-related curtailments. In Egypt, gross production is expected to decline modestly, while G7adjusted volumes should grow slightly year-over-year, to

APA CORPORATION ANNOUNCES FOURTH-QUARTER AND FULL-YEAR 2024 FINANCIAL AND OPERATIONAL

RESULTS

“Our 2025 plan builds on the progress achieved in 2024,” continued Christmann. “Through

inventory expansion in the Permian Basin and the renegotiation of both oil and gas economics in Egypt, we have positioned our core producing portfolio to deliver steady and predictable production. We expect to run eight rigs in the Permian and 12

rigs in Egypt, leading to a slight increase year-over-year in Permian and adjusted Egypt volumes. This activity set translates to a G8combined development capital budget for Permian and Egypt of$2.2-$2.3 billion, 17% lower than 2024 development capital when adjusting for Callon’s first-quarter 2024 spend.”

Additionally, APA is undertaking significant cost reduction initiatives aimed at streamlining the business and improving operating practices. The company is

targeting at least $350 million in sustainable annual savings by the end of 2027 across LOE, capital and overhead.

“Our cost reduction efforts

follow the strategic realignment of our portfolio over the last few years. Our objective is to return our cost structure to a leading position by streamlining every aspect of the business while enhancing the predictability and delivery of our

long-term plan. We are confident that our disciplined approach to capital allocation and rigorous cost management will underpin strong free cash flow growth over the next few years, which will be further bolstered by the GranMorgu project in

Suriname, with first oil in 2028,” Christmann concluded.

Year-End 2024 Proved Reserves

Worldwide estimated proved reserves totaled 969 million BOE at year-end 2024, 69% of which were classified as

proved developed.

Conference Call

APA will host a

conference call to discuss its fourth-quarter and full-year 2024 results at 10 a.m. Central time, Thursday, Feb. 27. The conference call will be webcast from APA’s website at www.apacorp.com and investor.apacorp.com. Following the conference

call, a replay will be available for one year on the “Investors” page of the company’s website.

RESULTS

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 arenon-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-GAAPmeasure.

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,” “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, and monetizations. 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

APA CORPORATION ANNOUNCES FOURTH-QUARTER AND FULL-YEAR 2024 FINANCIAL AND OPERATIONAL

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, 2023, and in our quarterly reports on Form10-Q (and in APA’s Form 10-K for the year ended December 31, 2024, when filed) 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, 2023 and in APA’s Form 10-K for the year ended December 31, 2024, when filed, available from APA at www.apacorp.com or by writing APA at: 2000 W. Sam Houston Pkwy S, Ste. 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.

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 acquisitions, 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, anon-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’son-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.

Reconciliation of debt to

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.
