APA Corporation Announces Third-Quarter 2021

Financial and Operational Results

Key Takeaways

HOUSTON, Nov. 3, 2021 – APA Corporation (Nasdaq: APA) today announced its financial and operational results for the third-quarter 2021.

APA reported a loss of $113 million, or $0.30 per diluted common share. When adjusted for items that impact the comparability of results, predominately a $446 million undiscounted net contingency recognized for asset retirement obligations associated with previously divested Gulf of Mexico properties, APA’s third-quarter earnings were $372 million, or $0.98 per diluted share. Net cash provided by operating activities was $771 million, and adjusted EBITDAX was $1.16 billion, making it the strongest quarterly performance of the year. The company anticipates the fourth quarter will be even stronger.

“APA delivered another excellent quarter, driven by strong U.S. well performance, continued capital and cost discipline, and better-than-expected commodity prices,” said John J. Christmann IV, APA’s CEO and president. “We generated $1.3 billion of Free Cash Flow in the first three quarters of 2021, and, at current strip pricing, we anticipate approximately $2 billion for the full-year. With the substantial strengthening of our balance sheet, a streamlined and more profitable enterprise and a planned capital program that will sustain or slightly grow production for the long term, we are committing to returning a minimum of 60% of our Free Cash Flow to shareholders. This began with the repurchase of 14.7 million shares in the month of October and today’s announced increase in our annual dividend to $0.50 per share, and we intend to continue these returns of capital to shareholders this quarter and into 2022.”

Third-Quarter Summary

Third-quarter reported production was 389,000 BOE per day, and adjusted production, which excludes Egypt noncontrolling interest and tax barrels, was 336,000 BOE per day. U.S. production was 237,000 BOE per day and international adjusted volumes were 99,000 BOE per day. APA’s third-quarter upstream capital investment was $228 million.

Production in the Southern Midland Basin and in Alpine High exceeded expectations during the quarter and the company recently added a third U.S. rig in its Austin Chalk play. Gross volumes in Egypt and the North Sea bottomed in the third quarter and have begun to move higher in the fourth quarter. In Egypt, the company has increased its rig count to 11 in anticipation of final approvals on modernized PSC terms before year end. In Block 58 Offshore Suriname, flow testing at Sapakara South and exploration work at Bonboni are continuing. Data collected from these operations will inform next steps in the exploration and appraisal program for the block.

Balance Sheet Progress and Share Repurchase Program

In August, the company significantly reduced its outstanding term debt through a $1.7 billion upsized bond tender, which was funded by cash on hand and borrowings from its revolving credit facility. At the end of the third quarter, APA’s total debt, excluding Altus Midstream, was $6.75 billion, and cash and cash equivalents were $268 million.

APA repurchased approximately 14.7 million shares in October under an existing authorization of 40 million shares. The company’s board of directors increased that authorization by an additional 40 million shares, bringing the total to 80 million shares, with approximately 65 million remaining at the end of October. In the fourth quarter, the company expects to return more than 60% of Free Cash Flow to shareholders.

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,” “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 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 Apache Corporation’s Form 10-K for the year ended December 31, 2020, filed with the Securities and Exchange Commission on February 25, 2021, and in our quarterly reports on Form 10-Q for a discussion of risk factors that affect our business.

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 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.

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.
