UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

On January 10, 2024, Chesapeake Energy Corporation ("Chesapeake") and Southwestern Energy Company ("Southwestern") entered into an all-stock agreement and plan of merger (the “Merger Agreement”). On October 1, 2024, Chesapeake and Southwestern completed the previously announced merger (the "Southwestern Merger" or the "Merger"). Subject to the terms and conditions of the Merger Agreement, each share of Southwestern common stock, par value $0.01 per share, issued and outstanding immediately prior to the close of the Merger (excluding certain shares held by Southwestern as treasury shares, or by Chesapeake, and certain equity awards of Southwestern) was converted into the right to receive 0.0867 (the “Exchange Ratio”) of a share of Chesapeake common stock, par value $0.01 per share (the “Merger Consideration”). No fractional shares of Chesapeake common stock were issued in the Merger, and holders of shares of Southwestern common stock received cash in lieu of fractional shares of Chesapeake common stock, if any, in accordance with the terms of the Merger Agreement.

After the Southwestern Merger, Chesapeake changed its name to Expand Energy Corporation (“Expand Energy”). References to “us,” “we,” “our,” “ours,” “Expand Energy” and the “Company” prior to October 1, 2024 refer to Chesapeake Energy Corporation and its consolidated subsidiaries prior to the Southwestern Merger and do not include Southwestern and its subsidiaries, while such references on or after October 1, 2024 refer to the combined company as a result of the Southwestern Merger, including Southwestern and its subsidiaries.

The following unaudited pro forma condensed combined balance sheet (the "pro forma balance sheet") and unaudited pro forma condensed combined statement of operations (the "pro forma statement of operations" and together with the pro forma balance sheet the "pro forma condensed combined financial statements") are derived from the historical consolidated financial statements of Expand Energy and Southwestern and have been adjusted to give effect to the Merger and the divestiture of our Eagle Ford assets (the “Eagle Ford Divestitures”) described below:

· On January 17, 2023, we entered into an agreement to sell a portion of our Eagle Ford assets to WildFire Energy I LLC for approximately $1.425 billion, subject to post-closing adjustments. This transaction closed on March 20, 2023 (with an effective date of October 1, 2022).

· On February 17, 2023, we entered into an agreement to sell a portion of our Eagle Ford assets to INEOS Energy for approximately $1.4 billion, subject to post-closing adjustments. This transaction closed on April 28, 2023 (with an effective date of October 1, 2022).

· On August 11, 2023, we entered into an agreement to sell the final portion of our Eagle Ford assets to SilverBow Resources, Inc. (“SilverBow”) for approximately $700 million, subject to post-closing adjustments. On July 30, 2024, Crescent Energy Company (“Crescent”) acquired SilverBow. Subject to the satisfaction of certain commodity price triggers, we may receive up to an additional $50 million cash consideration from Crescent shortly following the first anniversary of the transaction close date. This transaction closed on November 30, 2023 (with an effective date of February 1, 2023).

The pro forma balance sheet as of September 30, 2024 combines the historical balance sheets of Expand Energy and Southwestern as of September 30, 2024, and gives effect to the Merger as if it had been completed on September 30, 2024. The pro forma balance sheet is not adjusted for the Eagle Ford Divestitures as those had been completed and reflected in Expand Energy's historical balance sheet as of September 30, 2024. The pro forma statements of operations for the nine months ended September 30, 2024 and the year ended December 31, 2023, combine the historical consolidated statements of operations of Expand Energy (giving effect to the Eagle Ford Divestitures) and Southwestern, with the effects of the Merger as if each transaction had been completed on January 1, 2023.

UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

The unaudited pro forma condensed combined financial statements reflect the following pro forma adjustments related to the Merger, based on available information and certain assumptions that management believes are reasonable.

· the Merger will be accounted for using the acquisition method of accounting, with Expand Energy identified as the accounting acquirer;

· Certain reclassification adjustments to conform Southwestern's historical financial presentation to Expand Energy's financial statement presentation;

· the assumption of liabilities by Expand Energy for any remaining transaction-related expenses to be incurred; and

· the estimated tax impact of pro forma adjustments.

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

· the accompanying notes to the unaudited pro forma condensed combined financial statements;

· the historical audited consolidated financial statements of Expand Energy as of and for the year ended December 31, 2023, included in Expand Energy's Annual Report on Form 10-K filed on February 21, 2024;

· the historical audited consolidated financial statements for Southwestern as of and for the year ended December 31, 2023, included in Southwestern's Annual Report on Form 10-K filed on February 22, 2024 and incorporated by reference into this document;

· the historical unaudited condensed consolidated financial statements of Expand Energy as of and the for the nine months ended September 30, 2024, included in Expand Energy's Quarterly Report on Form 10-Q for the quarter ended September 30, 2024 filed on October 29, 2024;

· the historical unaudited condensed consolidated financial statements of Southwestern as of and the for the nine months ended September 30, 2024, included in this document;

· other information relating to Expand Energy and Southwestern contained in or incorporated by reference in this document.

The pro forma condensed combined financial statements are presented to reflect the Southwestern Merger and the Eagle Ford Divestitures for illustrative purposes only, and they do not represent what Expand Energy’s results of operations would have been had the Merger and the Eagle Ford Divestitures occurred on the date noted above, nor do they purport to project the future results of operations of the combined company following the transactions. The pro forma condensed combined financial statements are intended to provide information about the continuing impact of the transactions as if they had been consummated earlier. The pro forma adjustments are based on available information and certain assumptions that management believes are factually supportable as of the date of preparation as further described below. In the opinion of management, all adjustments necessary to present fairly the pro forma condensed combined financial statements have been made.

Expand Energy and Southwestern anticipate that certain non-recurring charges will be incurred in connection with the Merger, the substantial majority of which consist of employee severance costs, employee retention costs, fees paid to financial, legal and accounting advisors, integration costs and filing fees. Any such charge could affect the future results of the post-acquisition company in the period in which such charges are incurred; however, these costs are not expected to be incurred in any period beyond twelve months from the closing date of the Merger. Accordingly, the pro forma condensed combined financial statements reflect an estimated accrual for the effects of these non-recurring charges, which are not included in the historical financial statements of Expand Energy or Southwestern for the periods presented.

The pro forma condensed combined financial statements do not include the realization of any cost savings from operating efficiencies, synergies or other restructuring activities that might result from the Merger. Further, there may be additional charges related to the restructuring or other integration activities resulting from the Merger, the timing, nature and amount of which management cannot identify as of the date of this filing, and thus, such charges are not reflected in the pro forma condensed combined financial statements.

UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

As of the date of this filing, Expand Energy has not completed the detailed valuation study necessary to arrive at the required final estimates of the fair value of the acquired Southwestern assets and assumed liabilities and the related purchase price. As soon as practical, Expand Energy will identify the assets acquired and liabilities assumed and make final determinations of their fair values using relevant information available at that time. For purposes of the pro forma condensed combined financial statements, Expand Energy estimated the fair value of Southwestern’s assets and liabilities based on reviews of Southwestern’s SEC filings, preliminary valuation studies, discussions with Southwestern’s management and other due diligence procedures. The assumptions and estimates used to determine the preliminary purchase price allocation and fair value adjustments are described in the notes accompanying the unaudited pro forma condensed combined financial statements.

As a result of the foregoing, the pro forma adjustments are preliminary and subject to change as additional information becomes available and additional analysis is performed. The preliminary pro forma adjustments have been made solely for the purpose of providing the pro forma condensed combined financial statements presented herein. Any increases or decreases in the fair value of assets acquired and liabilities assumed upon completion of the final valuation will result in adjustments to the pro forma balance sheet and if applicable, the pro forma statements of operations. The final purchase price allocation may be materially different than that reflected in the preliminary purchase price allocation presented herein.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

1. Basis of Presentation

The unaudited pro forma condensed combined financial information has been derived from the historical consolidated financial statements of Expand Energy and Southwestern and gives pro forma effect to the events that are directly attributable to the Merger and the Eagle Ford Divestitures and are factually supportable. Certain of Southwestern's historical amounts have been reclassified to conform to Expand Energy's financial statement presentation. The unaudited pro forma condensed combined balance sheet as of September 30, 2024 gives effect to the Merger as if the Merger had been completed on September 30, 2024. The unaudited pro forma condensed combined statement of operations for the nine months ended September 30, 2024, and the year ended December 31, 2023, give effect to the Merger and the Eagle Ford Divestitures as if these transactions had been completed on January 1, 2023.

The unaudited pro forma condensed combined financial statements reflect pro forma adjustments that are described in the accompanying notes and are based on available information and certain assumptions that Expand Energy believes are reasonable; however, actual results may differ from those reflected in these statements. In Expand Energy’s opinion, all adjustments that are necessary to present fairly the pro forma information have been made. The following pro forma condensed combined 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 above, nor are they indicative of Expand Energy’s future financial position or results of operations. These pro forma condensed combined financial statements and the accompanying notes should be read in conjunction with the previously filed consolidated financial statements and related notes of Expand Energy and Southwestern for the periods presented.

The unaudited pro forma condensed combined financial information includes adjustments to conform Southwestern’s accounting policies to Expand Energy’s accounting policies, including adjusting Southwestern’s natural gas and oil properties to the successful efforts method. Southwestern followed the full cost pool method of accounting for natural gas and oil properties, while Expand Energy follows the successful efforts method of accounting for natural gas and oil properties. Certain costs that are expensed under the successful efforts method are capitalized under the full cost method, including unsuccessful exploration drilling costs, geological and geophysical costs, delay rentals on leases and general and administrative expenses directly related to exploration and development activities. Under the full cost method of accounting, property acquisition costs, costs of wells, related equipment and facilities and future development costs are all included in a single full cost pool, which is amortized on a units-of-production basis over total proved reserves. Under the successful efforts method of accounting, property acquisition costs are amortized on a units-of-production basis over total proved reserves, while costs of wells and related equipment and facilities are amortized on a units-of-production basis over proved developed reserves.

2. Unaudited Pro Forma Condensed Combined Balance Sheet

The Merger will be accounted for using the acquisition method of accounting for business combinations. The allocation of the preliminary estimated purchase price is based upon management’s estimates of and assumptions related to the fair value of assets to be acquired and liabilities to be assumed as of September 30, 2024 using currently available information. Due to the fact that the unaudited pro forma condensed combined financial information has been prepared based on these preliminary estimates, the final purchase price allocation and the resulting effect on Expand Energy’s financial position and results of operations may differ significantly from the pro forma amounts included herein. Expand Energy expects to finalize its allocation of the purchase consideration within one year subsequent to the closing date of the Merger.

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 Southwestern’s assets acquired and liabilities assumed as of the closing date of the Merger, which could result from changes in reserve estimates and other factors; and

· the tax bases of Southwestern’s assets and liabilities as of the closing date of the Merger.
