APA Corporation

501,708 Shares of Common Stock

This prospectus covers the resale by the selling stockholders identified in this prospectus of up to an aggregate of 501,708 shares of common stock, par value $0.625 per share (our “common stock”), of APA Corporation (the “Company”, “APA”, “our” or “we”) that may be obtained upon exercise of Series A warrants (the “warrants”) of the Company. The warrants were received by the selling stockholders upon the consummation of the merger of a wholly-owned subsidiary of the Company into Callon Petroleum Company (“Callon”) in exchange for their Series A warrants of Callon (the “Callon warrants”).

We are not selling any shares of our common stock under this prospectus, and we will not receive any of the proceeds from the sale or other disposition of shares of our common stock by the selling stockholders. Additionally, we will not receive any proceeds upon exercise of the warrants. This prospectus is not offering any warrants.

Shares of our common stock (these “securities”) obtained from the exercise of the warrants may be offered and sold by the selling stockholders from time to time in accordance with the provisions set forth under “Plan of Distribution.” The selling stockholders may offer and sell these securities to or through one or more underwriters, dealers or agents, who may receive compensation in the form of discounts, concessions or commissions, or directly to purchasers, on a continuous or delayed basis. The selling stockholders may offer and sell these securities at various times in amounts, at prices and on terms to be determined by market conditions and other factors at the time of such offerings. This prospectus describes the general terms of these securities and the general manner in which the selling stockholders will offer and sell these securities. A prospectus supplement, if needed, will describe the specific manner in which the selling stockholders will offer and sell these securities and also may add, update or change information contained or incorporated by reference in this prospectus. The names of any underwriters and the specific terms of a plan of distribution, if needed, will be stated in the prospectus supplement.

Our common stock is listed on Nasdaq Global Select Market (“Nasdaq”) under the symbol “APA.”

INVESTING IN OUR COMMON STOCK INVOLVES A NUMBER OF RISKS. SEE “RISK FACTORS” ON PAGE 3 TO READ ABOUT FACTORS YOU SHOULD CAREFULLY CONSIDER BEFORE INVESTING IN OUR COMMON STOCK.

Neither the U.S. Securities and Exchange Commission (the “SEC”) nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this prospectus is April 1, 2024.

ABOUT THIS PROSPECTUS

This prospectus is part of an “automatic shelf” registration statement that we filed with the SEC, as a “well-known seasoned issuer” as defined in Rule 405 under the Securities Act of 1933, as amended (the “Securities Act”), using a “shelf” registration process. Using this process, the selling stockholders may offer the securities described in this prospectus in one or more offerings. This prospectus provides you with a general description of us and the securities that may be offered by the selling stockholders. Because each of the selling stockholders may be deemed to be an “underwriter” within the meaning of the Securities Act, each time securities are offered by the selling stockholders pursuant to this prospectus, the selling stockholders may be required to provide you with this prospectus and, in certain cases, a prospectus supplement that will contain specific information about the selling stockholders and the terms of the securities being offered. The prospectus supplement may also add to, update or change the information contained in this prospectus. If there is any inconsistency between the information in this prospectus and any prospectus supplement, you should rely on the information in the prospectus supplement. Please carefully read this prospectus and any prospectus supplement, in addition to the information contained in the documents we refer to under the heading “Where You Can Find More Information” and “Information Incorporated by Reference.”

You should rely only on the information contained in this prospectus and in any applicable prospectus supplement, including any information incorporated by reference. Neither we nor the selling stockholders have authorized anyone to provide you with any information or to make any representations other than those contained in this prospectus or in any free writing prospectus made available by us. We and the selling stockholders take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you.

You should assume that the information appearing in this prospectus is accurate only as of the date on the cover of this prospectus and that any information we have incorporated by reference is accurate only as of the date of the document incorporated by reference. Our business, financial condition, results of operations and prospects may have changed since the date indicated on the cover page of such documents.

The distribution of this prospectus may be restricted by law in certain jurisdictions. You should inform yourself about and observe these restrictions. This prospectus does not constitute, and may not be used in connection with, an offer or solicitation by anyone in any jurisdiction in which the offer or solicitation is not authorized, or in which the person making the offer or solicitation is not qualified to do so, or to any person to whom it is unlawful to make the offer or solicitation.

RISK FACTORS

Before making an investment decision, you should carefully consider the risks described under “Risk Factors” in our most recent Annual Report on Form 10-K and in subsequent Quarterly Reports on Form 10-Q, together with all of the other information appearing in this prospectus or any applicable prospectus supplement or incorporated by reference herein or therein. The risks so described are not the only risks facing our company. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations. Our business, financial condition and results of operations could be materially adversely affected by any of these risks. Furthermore, the trading price of our securities could decline due to any of these risks, and you may lose all or part of your investment.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, any accompanying prospectus supplement and the documents incorporated by reference herein or therein may include “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). These statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. In some cases, you can identify forward-looking statements by terms such as “anticipate,” “project,” “intend,” “estimate,” “expect,” “believe,” “predict,” “budget,” “projection,” “goal,” “plan,” “forecast,” “target” or similar expressions intended to identify forward-looking statements.

All statements other than statements of historical facts included in this prospectus, any accompanying prospectus supplement and the documents incorporated by reference herein or therein are forward-looking statements. These statements may address activities, events or developments that we expect or anticipate will or may occur in the future, including such things as:

Although we believe that our plans, intentions and expectations reflected in or suggested by these forward-looking statements are reasonable, we can give no assurance that these plans, intentions or expectations will be achieved. We disclose important factors that could cause our actual results to differ materially from our expectations under “Risk Factors” in our most recent Annual Report on Form 10-K and in any subsequent Quarterly Reports on Form 10-Q. These factors, some of which are beyond our control, include the following:

4

All forward-looking statements speak only as of the date of the document in which they are contained; we disclaim any obligation to update these statements unless required by law, and we caution you not to place undue reliance on them.

All forward-looking statements, expressed or implied, included in this prospectus, any prospectus supplement and the documents incorporated by reference herein or therein are qualified in their entirety by this cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral forward-looking statements that we or persons acting on our behalf may issue.

In addition, we caution that reserve engineering is a process of estimating oil and natural gas accumulated underground and cannot be measured exactly. Accuracy of reserve estimates depend on a number of factors, including data available at the point in time, engineering interpretation of the data, and assumptions used by the reserve engineers as it relates to price and cost estimates and recoverability. New results of drilling, testing and production history may result in revisions of previous estimates and, if significant, would impact future development plans. As such, reserve estimates may differ from actual results of oil and natural gas quantities ultimately recovered.

USE OF PROCEEDS

We are not selling any shares of our common stock under this prospectus, and we will not receive any of the proceeds from the sale of shares of our common stock by the selling stockholders. All shares of our common stock offered by this prospectus are being registered for the account of the selling stockholders.

The shares of our common stock covered by this prospectus are issuable upon exercise of the warrants to purchase an aggregate of up to 501,708 shares of our common stock. The warrants may only be exercised on a cashless “net” exercise basis. Therefore, we will also not receive any proceeds from the selling stockholders upon exercise of the warrants.

The selling stockholders and any brokers, dealers or agents that participate in the distribution of shares of common stock may be deemed to be “underwriters” within the meaning of the Securities Act, and any discounts, concessions, commissions or fees received by them and any profit on the resale of shares sold by them may be deemed to be underwriting discounts and commissions.

The selling stockholders identified below may acquire at any time shares in addition to those registered hereby. In addition, the selling stockholders identified below may sell, transfer, assign or otherwise dispose of some or all of their shares in transactions exempt from or not subject to the registration requirements of the Securities Act.

Other Material Relationships

To our knowledge, none of the selling stockholders has, or has had within the past three years, any position, office or other material relationship with us or any of our predecessors or affiliates, other than (i) their ownership of the warrants and (ii) their ownership, prior to the Merger, of Callon’s securities, including the Callon warrants.

PLAN OF DISTRIBUTION

The shares of our common stock are being registered to permit the selling stockholders to offer and sell the offered shares from time to time after the date of this prospectus. We will not receive any of the proceeds from the sale or other distribution of our common stock, or any proceeds from the selling stockholders upon exercise of the warrants. We will bear the fees and expenses incurred by us in connection with our obligation to register the offered securities pursuant to the Registration Rights Agreement. If the shares are sold through underwriters or broker-dealers, we will not be responsible for underwriting discounts or commissions or agents’ commissions.

The selling stockholders may act independently of us in making decisions with respect to the timing, manner and size of each of their sales. The selling stockholders and certain of their successors, including certain transferees and assignees, may make sales of the shares of common stock included in this prospectus from time to time through one or more methods specified herein or through a combination of any of such methods or any other method permitted pursuant to applicable law. Such offers and sales may be made directly to purchasers, through underwriters, to dealers or through agents, on any stock exchange on which the shares are listed or otherwise at prices and under terms prevailing at the time of the sale, at prices related to the then-current market price, at fixed prices, at varying prices determined at the time of sale, at privately negotiated prices or any other method permitted pursuant to applicable law. Such sales may be effected by a variety of methods, including the following:

9

Additionally, a selling stockholder that is an entity may elect to make a direct or indirect distribution of its shares of common stock to its direct or indirect employees, directors, members, managers, general or limited partners, affiliates or stockholders pursuant to the registration statement of which this prospectus is a part. To the extent that such direct or indirect employees, directors, members, managers, general or limited partners, affiliates or stockholders are not affiliates of ours, such members, partners or stockholders would thereby receive freely tradeable shares of common stock pursuant to the distribution through a registration statement.

The selling stockholders may enter into derivative transactions with third parties or sell securities not covered by this prospectus to third parties in privately negotiated transactions.

The selling stockholders may enter into hedging transactions with broker-dealers or any other person, in connection with such broker dealer or other person who may in turn engage in short sales of the shares of common stock in the course of hedging the positions they assume. The selling stockholders also may sell shares short and deliver shares covered by this prospectus to close out the short positions or loan, pledge, or grant a security interest in, some or all the shares owned by them to broker-dealers that in turn may sell such shares. The selling stockholder may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The selling stockholders may also directly make offers to sell some or all of the shares of common stock included in this prospectus to, or solicit offers to purchase such shares from, purchasers from time to time.

If the selling stockholders use one or more underwriters in the sale, the underwriters will acquire the securities for their own account, and they may resell these securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The securities may be offered and sold to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more of such firms. In connection with those sales, underwriters may be deemed to have received compensation from the selling stockholders in the form of underwriting discounts or commissions and may also receive commissions from purchasers of the shares for which they may act as agents. Underwriters may resell the shares to or through dealers, and those dealers may receive compensation in the form of one or more discounts, concessions or commissions from the underwriters and commissions from purchasers for which they may act as agents.

Broker-dealers engaged by the selling stockholder may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholder (or, if any broker-dealer acts as agent for the purchaser of common stock, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with Financial Industry Regulatory Authority (“FINRA”) Rule 5110; and in the case of a principal transaction a markup or markdown in compliance with FINRA Rule 2121.

From time to time, the selling stockholders may sell the shares of common stock included in this prospectus to one or more dealers acting as principals. The dealers, which may be deemed to be “underwriters” as that term is defined in the Securities Act, may then resell the shares to purchasers.

The selling stockholders may designate broker-dealers as agents from time to time to solicit offers from purchasers to purchase the shares of common stock included in this prospectus, or to sell such shares in ordinary brokerage transactions, on their behalf. Such broker-dealers may be deemed to be “underwriters” as that term is defined in the Securities Act in such offering.

The selling stockholders or their respective underwriters, broker-dealers, or agents may make sales of the shares of common stock that are deemed to be an at-the-market offering as defined in Rule 415 of the Securities Act,

10

which includes sales of such shares made directly on or through any stock exchange on which the shares are listed, the existing trading market for the shares, or in the over-the-counter market or otherwise.

From time to time, one or more of the selling stockholders may pledge, hypothecate or grant a security interest in some or all of the shares of common stock owned by them. In the event of default, the pledgees, secured parties or persons to whom the shares have been hypothecated will, to the extent registration rights are transferable and are transferred upon foreclosure, be deemed to be selling stockholders under this prospectus and may offer and sell common stock from time to time under this prospectus, or, to the extent required under the applicable securities laws, under an amendment to this prospectus under Rule 424 or other applicable provision of the Securities Act. The number of shares offered under this prospectus by a given selling stockholder will decrease as and when such events occur. In addition, a selling stockholder may, from time to time, sell the shares short, and, in those instances, this prospectus may be delivered in connection with the short sales, and the shares offered under this prospectus may be used to cover short sales.

In addition to the transactions described above, the selling stockholders may sell the shares of common stock included in this prospectus under Rule 144 or in compliance with any other available exemptions from the registration requirements under the Securities Act, if, when and to the extent such exemption is available to it at the time of such sale, rather than pursuant to this prospectus.

The selling stockholders may decide to sell all or a portion of the securities offered by them pursuant to this prospectus or may decide not to sell any securities under this prospectus. In addition, the selling stockholders may transfer, sell or dispose of the securities by other means not described in this prospectus.

The selling stockholders and any other persons participating in the sale or distribution of shares of common stock will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M. Regulation M may limit the timing of purchases and sales of any of the shares by the selling stockholders and any other such persons. In addition, Regulation M may restrict the ability of any person engaged in the distribution of the shares to engage in market-making activities with respect to the shares being distributed for a period of up to five business days before the distribution. This may affect the marketability of the shares and the ability of any person or entity to engage in market-making activities with respect to the shares.

To the extent required, the securities to be sold, the names of the selling stockholders, the respective purchase prices and public offering prices, the names of any agents, dealers or underwriters and any applicable commissions or discounts with respect to a particular offering will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

We have agreed to indemnify, in certain circumstances, the selling stockholders against certain liabilities to which they may become subject in connection with the sale of the shares of common stock included in this prospectus, including liabilities arising under the Securities Act. Each of the selling stockholders has agreed to indemnify us in certain circumstances against certain liabilities to which we may become subject in connection with the sale of such shares, including liabilities arising under the Securities Act. We have also agreed that if the indemnification described above is held by a court or government agency of competent jurisdiction to be unavailable to any indemnified party or is insufficient to hold them harmless in respect of any losses, then each such indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of such indemnified party on the other in connection with the statements or omissions that resulted in such losses, as well as any other relevant equitable considerations. We and the selling stockholders may agree to indemnify underwriters, dealers and agents who participate in the distribution of the shares included in this prospectus against certain liabilities to which they may become subject in connection with the sale of such shares, including liabilities arising under the Securities Act.

11

Certain of the underwriters and their affiliates may engage in transactions with and may perform services for us or our affiliates in the ordinary course of business.

We have agreed to pay the expenses of the registration of the shares of common stock offered and sold by the selling stockholders under the registration statement of which this prospectus forms a part, including, but not limited to, all registration and filing fees, fees and expenses of our counsel and accountants, and to reimburse the selling stockholders for any legal fees and expenses reasonably incurred in connection with defending against certain liabilities. The selling stockholders will pay any underwriting discounts and commissions applicable to the shares sold by the selling stockholders.

A prospectus and accompanying prospectus supplement in electronic form may be made available on the websites maintained by the underwriters of a given offering. The underwriters may agree to allocate a number of securities for sale to their online brokerage account holders. Such allocations of securities for internet distributions will be made on the same basis as other allocations. In addition, securities may be sold by the underwriters to securities dealers who resell securities to online brokerage account holders.

To the extent required, this prospectus may be amended or supplemented from time to time to describe a specific plan of distribution. The place and time of delivery for the securities in respect of which this prospectus is delivered will be set forth in the accompanying prospectus supplement.

In connection with offerings of securities under the registration statement of which this prospectus forms a part and in compliance with applicable law, underwriters, brokers or dealers may engage in transactions that stabilize or maintain the market price of the securities at levels above those that might otherwise prevail in the open market. Specifically, underwriters, brokers or dealers may over-allot in connection with offerings, creating a short position in the securities for their own accounts. For the purpose of covering a syndicate short position or stabilizing the price of the securities, the underwriters, brokers or dealers may place bids for the securities or effect purchases of the securities in the open market. Finally, the underwriters may impose a penalty whereby selling concessions allowed to syndicate members or other brokers or dealers for distribution of the securities in offerings may be reclaimed by the syndicate if the syndicate repurchases previously distributed securities in transactions to cover short positions, in stabilization transactions or otherwise. These activities may stabilize, maintain or otherwise affect the market price of the securities, which may be higher than the price that might otherwise prevail in the open market, and, if commenced, may be discontinued at any time. These transactions may be effected on or through any stock exchange on which the shares are listed, the existing trading market for the shares, or in the over-the-counter market or otherwise.

Section 145 of the Delaware General Corporation Law, inter alia, authorizes a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending, or completed action, suit, or proceeding, other than an action by or in the right of the corporation, because such person is or was a director, officer, employee, or agent of the corporation or was serving at the request of the corporation as a director, officer, employee, or agent of another corporation or other enterprise, against expenses, including attorneys’ fees, judgments, fines, and amounts paid in settlement actually and reasonably incurred by such person in connection with such suit or proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reason to believe such person’s conduct was unlawful. Similar indemnity is authorized for such persons against expenses, including attorneys’ fees, actually and reasonably incurred in defense or settlement of any such pending, completed, or threatened action or suit by or in the right of the corporation if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, and provided further that, unless a court of competent jurisdiction otherwise provides, such person shall not have been adjudged liable to the corporation. Any such indemnification may be made only as authorized in each specific case upon a determination by the stockholders or disinterested directors that indemnification is proper because the indemnitee has met the applicable standard of conduct.

Section 145 further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee, or agent of another corporation or enterprise, against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the corporation would otherwise have the power to indemnify such person. The Company maintains policies insuring its and its subsidiaries’ officers and directors against specified liabilities for actions taken in such capacities, including liabilities under the Securities Act.

II-1

Article VII of the Company’s amended and restated bylaws provides, in substance, that directors, officers, employees, and agents of the Company shall be indemnified to the fullest extent permitted by the Delaware General Corporation Law. Additionally, Article Seventeenth of the Company’s amended and restated certificate of incorporation eliminates in specified circumstances the monetary liability of directors of the Company for a breach of their fiduciary duty as directors. These provisions do not eliminate the liability of a director:

The foregoing statements are subject to the detailed provisions of Section145 of the Delaware General Corporation Law and the Company’s amended and restated certificate of incorporation and amended and restated bylaws.

Item 17. Undertakings

The undersigned registrant hereby undertakes:

(1) to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Filing Fee” table in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (i), (ii) and (iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act to any purchaser:

(A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed

II-3

to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which the prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5) That, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(6) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Re: Form S-3

Ladies and Gentlemen:

We have acted as special counsel to APA Corporation, a Delaware corporation (the “Company”), in connection with its filing on the date hereof with the Securities and Exchange Commission (the “Commission”) of a Registration Statement on Form S-3 (the “Registration Statement”), under the Securities Act of 1933, as amended (the “Act”), relating to the offer and sale, from time to time, by certain stockholders of the Company of up to 501,708 shares of common stock of the Company (the “Common Stock”, and such shares, the “Warrant Shares”). The Warrant Shares will be issued upon exercise of the Series A warrants (the “Warrants”) that were received by the holders thereof (as of the date hereof) upon the consummation of the merger pursuant to that certain Agreement and Plan of Merger, dated as of January 3, 2024, by and among the Company, Astro Comet Merger Sub Corp., and Callon Petroleum Company (“Callon”), in exchange for their Series A warrants of Callon.

In rendering the opinion stated herein, we have examined and relied upon the following:

This opinion is provided pursuant to the requirements of Item 601(b)(5) of Regulation S-K under the Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement, other than as expressly stated herein with respect to the issuance of the Warrant Shares.

We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and such agreements, certificates and receipts of public officials, certificates of officers or other representatives of the Company and others and such other documents as we have deemed necessary or appropriate as a basis for the opinions stated below.

In this opinion, we have relied, with your consent, upon oral and written representations of officers of the Company and certificates of officers of the Company and public officials with respect to the accuracy of the factual matters addressed in such representations and certificates. In addition, in rendering this opinion, we have assumed without verification the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity of certified copies submitted to us with the original documents to which such certified copies relate and the legal capacity of all individuals executing any of the foregoing documents.

Page 2

The opinions stated herein presume that: (i) the Registration Statement will be effective and will comply with applicable laws at the time the Warrant Shares are offered or issued as contemplated by the Registration Statement; (ii) if applicable, a prospectus supplement or term sheet (“Prospectus Supplement”) will have been prepared and filed with the Commission describing the Warrant Shares offered thereby and will comply with all applicable laws; (iii) all Warrant Shares will be sold in compliance with applicable federal and state securities laws and in the manner stated in the Registration Statement and, if applicable, the appropriate Prospectus Supplement; (iv) the Warrants have been duly executed and delivered by the Company and constitute valid and legally binding obligations of the Company, and (v) at the time of the issuance of any Warrant Shares, (a) the Company will validly exist and be duly qualified and in good standing under the laws of its jurisdiction of formation, (b) the Company will comply with all applicable notice requirements regarding uncertificated shares provided in the General Corporation Law of the State of Delaware (the “DGCL”), (c) the Company will have the necessary organizational power and authority to issue the Warrant Shares, (d) upon the issue of any of the Warrant Shares, the total number of shares of Common Stock then issued and outstanding will not exceed the total number of shares of Common Stock that the Company is then authorized to issue under its certificate of incorporation and by the board of directors of the Company in connection with the offering contemplated by the Registration Statement, and (e) the Company will have made available for issuance such number of Warrant Shares.

Based upon the foregoing and subject to the qualifications and assumptions stated herein, we are of the opinion that when the Warrant Shares have been issued by the Company in accordance with the applicable Warrants and the Warrant Agreement, the Warrant Shares will be validly issued, fully paid and non-assessable.

We have not considered, and we express no opinion as to any law other than the DGCL.

We hereby consent to be named in the Registration Statement and in the related prospectus contained therein as the attorneys who passed upon the legality of the securities being registered pursuant to the Registration Statement and to the filing of a copy of this opinion as Exhibit 5.1 to the Registration Statement. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act. This opinion speaks as of its date, and we undertake no (and hereby disclaim any) obligation to update this opinion.
