Exhibit 99.2

UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

On April 1, 2024, APA Corporation (“APA” or the “Company”) completed its acquisition of Callon Petroleum Company (“Callon”), through the merger of Astro Comet Merger Sub Corp., a Delaware corporation and a wholly owned subsidiary of APA (“Merger Sub”), with and into Callon (the “merger”), pursuant to the Agreement and Plan of Merger, dated as of January 3, 2024 (the “Merger Agreement”), among APA, Merger Sub, and Callon. Upon completing the merger, Callon stockholders received, in exchange for each eligible share of Callon common stock, 1.0425 shares of APA common stock, par value $0.625 per share (“APA common stock”).

The following unaudited pro forma combined financial statements (“pro forma financial statements”) have been prepared from the respective historical consolidated financial statements of APA and Callon, adjusted to give effect to (i) the merger, (ii) Callon’s acquisition of Percussion Petroleum Operating II, LLC (“Percussion”), which was completed on July 3, 2023, (iii) Callon’s disposition of its Eagle Ford assets, which was completed on July 3, 2023, (iv) the extinguishment of Callon’s outstanding debt, and (v) the issuance of new debt (collectively, the “Transactions”). The unaudited pro forma combined balance sheet (the “pro forma balance sheet”) combines the historical consolidated balance sheets of APA and Callon as of December 31, 2023, giving effect to the Transactions as if they had been consummated on December 31, 2023, except for Callon’s acquisition of Percussion and Callon’s divestiture of its Eagle Ford assets having been completed on July 3, 2023. The unaudited pro forma combined statement of operations (the “pro forma statement of operations”) combines the historical consolidated statements of operations of APA and Callon for the year ended December 31, 2023, giving effect to the Transactions as if they had been consummated on January 1, 2023.

The pro forma financial statements contain certain reclassification adjustments to conform the historical Callon financial statement presentation to APA’s financial statement presentation.

The pro forma financial statements have been developed from and should be read in conjunction with:

•

the audited consolidated financial statements of APA included in its Annual Report on Form 10-K for the year ended December 31, 2023;

•

the audited consolidated financial statements of Callon included in its Annual Report on Form 10-K for the year ended December 31, 2023;

•

Callon’s Current Report on Form 8-K filed on July 7, 2023 (the “July 2023 8-K”), to present the effects of the Percussion acquisition and Eagle Ford divestiture; and

•

other information relating to APA and Callon contained in or incorporated by reference into this filing.

The pro forma financial statements are provided for illustrative purposes only and are not intended to represent what APA’s financial position or results of operations would have been had the Transactions actually been consummated on the assumed dates, nor do they purport to project the future operating results or the financial position of the combined company following the merger. The pro forma financial statements do not reflect events that have occurred or may occur after completion of the merger, including, but not limited to, the anticipated realization of savings from potential operating efficiencies, cost savings, or economies of scale that the combined company may achieve with respect to the combined operations. Specifically, the pro forma statement of operations does not include projected synergies expected to be achieved as a result of the merger or any associated costs incurred to achieve any projected synergies. The pro forma statement of operations also excludes the costs associated with subsequent integration activities related to the merger.

The pro forma financial statements have been prepared to reflect adjustments to APA’s historical consolidated financial information. Accordingly, the pro forma financial statements reflect the following:

•

the merger is accounted for as a business combination using the acquisition method of accounting, with APA identified as the acquirer, and the issuance of shares of APA common stock as merger consideration;

•

each eligible share of Callon common stock and each Callon equity award converted or settled as part of the merger was converted automatically into the right to receive 1.0425 shares of APA common stock, in accordance with the terms of the Merger Agreement;

•

Callon’s acquisition of Percussion;

•

Callon’s disposition of its Eagle Ford assets;

•

the assumption of liabilities for merger-related expenses;

•

the reclassification of certain of Callon’s historical amounts to conform to APA’s financial statement presentation;

•

the recognition of the estimated tax impact of the pro forma adjustments; and

•

the extinguishment of Callon’s senior notes and credit facility and subsequent refinancing by APA.

Assumptions and estimates underlying the pro forma adjustments are described in the accompanying notes, which should be read in conjunction with the pro forma financial statements. The fair value of Callon’s assets and liabilities is based on the actual assets and liabilities of Callon that existed as of the date the merger was completed. In addition, the value of the consideration paid by APA upon completion of the merger is based on the price of APA common stock on the date the merger was completed. In APA’s opinion, all adjustments are based on available information and assumptions that APA believes are reasonable and necessary to present fairly the pro forma information.

NOTES TO THE UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

NOTE 1. Basis of Presentation

The APA and Callon historical financial information have been derived from each respective company’s Annual Report on Form 10-K for the year ended December 31, 2023. Certain of Callon’s historical amounts have been reclassified to conform to APA’s financial statement presentation. The unaudited pro forma adjustments related to Callon’s Percussion acquisition and Eagle Ford divestiture are from the July 2023 8-K. These pro forma financial statements should be read in conjunction with the historical financial statements and related notes thereto of APA and Callon, as well as the pro forma financial information included in the July 2023 8-K.

The pro forma balance sheet gives effect to the Transactions as if they had occurred on December 31, 2023. No adjustments related to the Percussion acquisition or Eagle Ford divestiture have been applied to the pro forma balance sheet, as they are already reflected in Callon’s historical consolidated balance sheet as of December 31, 2023. The pro forma statement of operations gives effect to the Transactions as if they had occurred on January 1, 2023.

The pro forma financial statements reflect pro forma adjustments that are described in the accompanying notes and are based on currently available information. In APA’s opinion, all adjustments have been made that are necessary to present fairly the pro forma financial statements. The pro forma financial statements do not purport to represent what the combined company’s financial position or results of operations would have been if the Transactions had actually occurred on the dates indicated, nor are they indicative of APA’s future financial position or results of operations. Actual results may differ materially from the assumptions and estimates reflected in these pro forma financial statements.

NOTE 2. Purchase Price Allocation

APA has determined it is the accounting acquirer in the merger, which is accounted for under the acquisition method of accounting for business combinations in accordance with Accounting Standards Codification 805, “Business Combinations”. The allocation of the estimated purchase price with respect to the merger is based upon APA’s estimates of, and assumptions related to, the fair value of assets and liabilities assumed as of the date the merger was completed, using currently available information and is subject to change if additional information about the facts and circumstances that existed at the acquisition date becomes available. Because the pro forma financial statements have been prepared based on these preliminary estimates, the final purchase price allocation and the resulting effect on APA’s financial position and results of operations of the combined company may be materially different from the pro forma amounts included herein. APA expects to finalize the purchase price allocation as soon as practicable, but no later than one year from April 1, 2024.

The preliminary purchase price allocation is subject to change due to several factors, including, but not limited to:

•

changes in the estimated fair value of Callon’s identifiable assets acquired and liabilities assumed as of the closing of the merger, which could result from APA’s additional valuation analysis, reserve estimates, discount rates and other factors; and

•

changes in the recognized tax impact of the Transactions, including the presentation and measurement of related deferred tax assets and liabilities, as of the closing of the Transactions, which could result from changes in reserve estimates and other assumptions.

Based upon the merger consideration transferred, the fair value of the assets acquired and liabilities assumed is recorded as follows (shown in millions, except exchange ratio and price per share data):


Consideration transferred:
Callon common stock outstanding on April 1, 2024, prior to completion of the merger		67
Exchange ratio		1.0425

(b)

Additional consideration represents the fair value of APA shares that replaced Callon equity awards that are attributable to pre-merger services provided.

Under the Merger Agreement, each Callon stockholder was entitled to receive 1.0425 shares of APA common stock for, as applicable, (i) each eligible share of Callon common stock and (ii) each Callon equity award converted or settled as part of the merger, with cash in lieu of fractional shares.

NOTE 3. Pro Forma Adjustments

Adjustments included in the columns labeled “Transaction Accounting Adjustments” and “Financing Adjustments” in the pro forma financial statements are as follows:

(a)

Reflects immaterial purchase price allocation adjustment to record the estimated fair value of various assets and liabilities assumed from Callon based on the estimated fair value determined as of the date the merger was completed.

(b)

Reflects a purchase price allocation adjustment resulting in (i) a decrease in Callon’s proved oil and gas properties to record the properties at their estimated fair value, (ii) the elimination of Callon’s Historical, As Adjusted accumulated depletion, depreciation and amortization (“DD&A”) balances, and (iii) a decrease in Callon’s unproved oil and gas properties to their estimated fair value. The resulting estimated fair value of oil and gas properties acquired was allocated approximately $3.6 billion to proved properties and $929 million to unproved properties.

(c)

Reflects transaction accounting adjustments to record APA’s estimated fair value of other property and equipment.

(d)

Reflects an adjustment to deferred income taxes to record the estimated deferred income tax effects of combining APA’s and Callon’s operations. For pro forma purposes, it is assumed that in 2023, the combined group released a signification portion of its U.S. valuation allowance. Approximately $369 million of this adjustment reflects an increase Callon’s deferred tax asset assumed in the transaction and associated release of valuation allowance recorded through continuing operations. In addition, an estimated deferred income tax benefit of $24 million was recorded for the transaction accounting adjustments using APA’s statutory rate in effect for the period ending December 31, 2023.

(e)

Reflects the adjustment of $194 million related to the Callon Historical, As Adjusted debt due to the re-measurement of debt at fair value and the adjustment of $13 million to write off Callon’s deferred financing fees included within the Callon Historical, As Adjusted Deferred charges and other financial statement line. The pro forma interest expense includes the impact of the write off of deferred financing fees.

(f)

Reflects transaction accounting adjustments to record APA’s estimated fair value adjustment related to right-of-use assets and lease liabilities.

(g)

Reflects transaction accounting adjustments to record nonrecurring transaction costs of approximately $114 million that were incurred by APA and Callon, including advisory, legal, regulatory, accounting, valuation and other professional fees that are not capitalized as part of the Transactions.

(h)

Reflects a transaction accounting adjustment to record the estimated fair value of the assumed Callon asset retirement obligations, which increased by $93 million. The pro forma income statement includes a corresponding adjustment to accretion expense in relation to the fair value of the asset retirement obligations.

(i)

Reflects a $26 million adjustment to eliminate the Callon Historical, As Adjusted cash settled awards and record the impact of the issuance of new APA awards and the transfer of other consideration upon closing of the merger.

(j)

Reflects adjustments to eliminate Callon Historical, As Adjusted equity balances in accordance with the acquisition method of accounting and record the impact of the issuance of consideration in connection with the merger. The impact of pro forma merger adjustments on total equity are summarized below (shown in millions):


	Elimination of Callon’s Historical Equity			Issuance of APA Common Stock		Pro Forma Equity Adjustments
Common stock	$	(1	)	$	43	$	42
Additional paid-in capital		(4,187	)		2,371		(1,816	)
Accumulated deficit		196			—		196

Total equity	$	(3,992)		$	2,414	$	(1,578	)

(k)

Reflects the pro forma adjustment related to the extinguishment of the historical Callon debt and the issuance of a new $1.5 billion senior unsecured delayed-draw term loan by APA, cash, and the use of APA’s existing credit facility. For the purposes of the pro forma financial statements, it was assumed that the remaining debt was repaid using APA’s existing credit facility and cash available as of December 31, 2023. The unsecured delayed-draw term loan will mature in three years. Pro forma interest expense includes estimates for the new term loan, including the impact of changes to amortization of debt issuance costs and from purchase accounting adjustments. The pro forma interest expense is based on a weighted average interest rate of 7.1%. The actual interest rate will be based on market and other conditions. For each 1/8% (12.5 basis points) change in the estimated weighted average interest rate for the new term loan, interest expense would increase or decrease by approximately $2 million per year. The pro forma interest expense associated with APA’s existing credit facility is based on a weighted average interest rate of 6.6%. In addition, an estimated deferred income tax benefit of $8 million was recorded for the financing accounting adjustments using APA’s statutory rate in effect for the period ending December 31, 2023.

Basis of Presentation

APA has derived the Callon Historical, As Adjusted unaudited pro forma financial statements from Callon’s historical accounting records. No adjustments related to Callon’s acquisition of Percussion or the Eagle Ford divestiture have been applied to the unaudited reclassified balance sheet. Both the Percussion acquisition and Eagle Ford divestiture closed on July 3, 2023, and are reflected in Callon’s historical consolidated balance sheet as of December 31, 2023. The unaudited pro forma statement of operations gives effect to the Percussion and Eagle Ford transactions as if they had occurred on January 1, 2023, and are based on the pro forma information presented in the July 2023 8-K and information provided by Callon management.

APA has presented the unaudited pro forma financial information for informational purposes only and the unaudited pro forma financial statements are not necessarily indicative of what the Callon Historical, As Adjusted financial position or results of operations would actually have been had the Percussion and Eagle Ford transactions been completed on the dates indicated.

NOTE 5. Supplemental Pro Forma Oil, NGL and Natural Gas Reserves Information

The following tables present (i) the estimated pro forma combined net proved developed and undeveloped oil, NGL and natural gas reserves as of December 31, 2023, (ii) the estimated pro forma combined standardized measure of discounted future net cash flows as of December 31, 2023, and (iii) the estimated sources of changes in pro forma combined standardized measure of discounted future net cash flows for the year ended December 31, 2023. The amounts below were derived from each of APA’s and Callon’s Annual Report on Form 10-K for the year ended December 31, 2023. This estimated pro forma combined oil, NGL and natural gas reserves information is not necessarily indicative of the results that might have occurred had the merger been completed on December 31, 2023, and is not intended to be a projection of future results. Future results may vary significantly from the results presented.

This pro forma reserve, production and standardized measure information gives effect to the Transactions as if they had been completed on January 1, 2023, including Callon’s acquisition of Percussion and divestiture of its Eagle Ford assets completed on July 3, 2023; however, the proved reserves and standardized measures presented below represent the respective estimates made as of December 31, 2023, by APA and Callon while they were separate companies. These estimates have not been updated for changes in development plans or other factors, which have occurred or may occur subsequent to (i) December 31, 2023, or (ii) the merger. This pro forma information has been prepared for illustrative purposes and is not intended to be a projection of future results of the combined company. Future results may vary significantly from the results presented as of December 31, 2023.

Pro Forma Combined Net Proved Developed and Undeveloped Oil, NGL and Natural Gas Reserves

The proved reserves of Callon are based on Callon’s development plans and reserve estimation methodologies. Because APA will develop such proved reserves in accordance with its own development plan and, in the future, will estimate proved reserves in accordance with its own methodologies, the estimates presented herein for Callon may not be representative of APA’s future proved reserve estimates. The following tables present the estimated pro forma combined net proved developed and undeveloped oil and gas reserves information as of December 31, 2023, along with a summary of changes in quantities of net remaining proved reserves during the year ended December 31, 2023:

Amendment Description	On April 1, 2024, APA Corporation, a Delaware corporation (“APA”), filed a Current Report on Form 8-K (the “Original Report”) to report that APA completed its acquisition of Callon Petroleum Company, a Delaware corporation (“Callon”), pursuant to the Agreement and Plan of Merger, dated January 3, 2024, by and among APA, Astro Comet Merger Sub Corp., a Delaware corporation and wholly owned subsidiary of APA (“Merger Sub”), and Callon. At the closing, Merger Sub merged with and into Callon, with Callon as the surviving entity (the “Merger”). This amendment to the Original Report (the “Amendment”) is being filed to provide the financial statements and pro forma financial information required by Item 9.01 of Form 8-K. The pro forma financial information included in this Amendment has been presented for informational purposes only, as required by Form 8-K. It does not purport to represent the actual results of operations that APA and Callon would have achieved had the companies been combined during the periods presented in the pro forma financial information and is not intended to project the future results of operations that the combined company may achieve after completion of the Merger. Except as described in this Amendment, all other information in the Original Report remains unchanged.
