Introductory Note

On October 1, 2024 (“Closing Date”), Southwestern Energy Company, a Delaware corporation (“Southwestern” or the “Company”), completed its previously announced merger with Chesapeake Energy Corporation, an Oklahoma corporation (“Chesapeake”), pursuant to the terms of that certain Agreement and Plan of Merger, dated as of January 10, 2024 (the “Merger Agreement”), by and among Southwestern, Chesapeake, Hulk Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Chesapeake (“Merger Sub”) and Hulk LLC Sub, LLC, a Delaware limited liability company and wholly owned subsidiary of Chesapeake (“Merger Sub LLC”). Pursuant to the Merger Agreement, immediately following the Effective Time, Chesapeake changed its name to “Expand Energy Corporation” (the “Company” or “Expand Energy”). In addition, Chesapeake changed its NASDAQ ticker symbol “CHK” to “EXE” and expects to begin trading under the “EXE” trading symbol effective as of the open of trading on the NASDAQ on October 2, 2024.

The Mergers

Pursuant to the Merger Agreement, at the Effective Time (as defined below), Merger Sub merged with and into Southwestern (the “First Merger”), with Southwestern surviving the First Merger as a direct wholly owned subsidiary of Chesapeake, and, subsequently, Southwestern merged with and into Merger Sub LLC, with Merger Sub LLC continuing as the surviving entity (the “Surviving LLC”) and as a direct, wholly owned subsidiary of Chesapeake (the “Second Merger”), and, subsequently, the Surviving LLC merged with and into Chesapeake, with Chesapeake continuing as the surviving entity (together, with the First Merger and Second Merger, the “Mergers”), and each eligible share of common stock of Southwestern, par value $0.01 per share (the “Southwestern Common Stock”) issued and outstanding immediately prior to the Effective Time was converted automatically into the right to receive 0.0867 (the “Exchange Ratio”) shares of Chesapeake Common Stock, with cash paid in lieu of the issuance of any fractional shares, in each case, as provided in the Merger Agreement.

In addition, at the Effective Time:

each outstanding and unexercised option award of Southwestern as of immediately prior to the Effective Time ceased to represent a right to acquire shares of Southwestern Common Stock and was automatically canceled and terminated without consideration payable or owed thereto;

each outstanding restricted stock award of Southwestern was automatically fully vested and each such restricted stock award was converted into the right to receive a number of shares of Chesapeake Common Stock equal to (i) the Exchange Ratio, multiplied by (ii) the total number of shares of Southwestern Common Stock attributable to such restricted stock award;

each outstanding restricted stock unit award of Southwestern under Southwestern’s Nonemployee Director Deferred Compensation Plan was automatically fully vested, canceled, and converted into the right to receive a number of shares of Chesapeake Common Stock equal to (i) the Exchange Ratio, multiplied by (ii) the total number of shares of Southwestern Common Stock subject to such restricted stock unit award, together with accrued dividend equivalent payments in each case issuable and payable at the times specified in Southwestern’s Nonemployee Director Deferred Compensation Plan and in accordance with such director’s deferral elections as set forth in the applicable Deferred Compensation Agreement;

each outstanding restricted stock unit award of Southwestern that (i) was granted pursuant to Southwestern’s 2013 Incentive Plan, or (ii) was granted prior to the date of the Merger Agreement and was held by an employee of Southwestern or its Subsidiaries (as defined in the Merger Agreement) who was terminated upon or immediately after the Effective Time, and was subject only to time-based vesting conditions, was fully vested, canceled and converted into the right to receive a number of shares of Chesapeake Common Stock equal to (A) the Exchange Ratio, multiplied by (B) the total number of shares of Southwestern Common Stock subject to each such restricted stock unit award, together with accrued dividend equivalent payments, in each case issuable and payable in accordance with the terms of the applicable award agreement;

each outstanding restricted stock unit award that was granted pursuant to Southwestern’s 2022 Incentive Plan (and not described above) and that was subject only to time-based vesting conditions was canceled and converted into an award of restricted stock units in respect of shares of Chesapeake Common Stock (rounded to the nearest whole share) equal to the product of (i) the total number of shares of Southwestern Common Stock subject to such restricted stock unit award immediately prior to the Effective Time multiplied by (ii) the Exchange Ratio. Such restricted stock unit award shall vest and become payable on the same terms and conditions (including “double-trigger” vesting provisions) as are set forth in the corresponding award agreement (except that such award will be payable in Chesapeake Common Stock);

each outstanding performance unit award that (i) was granted pursuant to the Southwestern’s 2013 Incentive Plan, or (ii) was granted prior to the date of the Merger Agreement and was held by an employee of Southwestern or its Subsidiaries (as defined in the Merger Agreement) that was terminated upon or immediately after the Effective Time was (A) automatically fully vested and became payable at the greater of (1) the level based on actual performance determined as of immediately prior to the Effective Time in accordance with the terms of the applicable award agreement and (2) the target level (the number of shares of Southwestern Common Stock payable pursuant to the foregoing, the “Earned Company Performance Shares”), and (B) canceled and converted into the right to receive a number of shares Chesapeake Common Stock equal to (1) the Exchange Ratio, multiplied by (2) the number of Earned Company Performance Shares, together with accrued dividend equivalent payments, in each case issuable and payable in accordance with the terms of the applicable award agreement;

each outstanding performance unit award of Southwestern that was granted pursuant to Southwestern’s 2022 Incentive Plan (and not described above) was deemed to correspond to a number of Earned Company Performance Shares, and was canceled and converted into an award of time-based vesting restricted stock units in respect of that number of shares of Chesapeake Common Stock (rounded to the nearest whole share) equal to (i) the number of Earned Company Performance Shares with respect to such performance unit award multiplied by (ii) the Exchange Ratio. Such restricted stock units shall time-vest at the end of the original performance period and are otherwise subject to and payable on the same terms and conditions (including “double-trigger” vesting provisions) as are set forth in the corresponding award agreement (except that such award will be payable in shares of Chesapeake Common Stock);

each outstanding performance cash unit award of Southwestern that (i) was granted pursuant to Southwestern’s 2013 Incentive Plan, or (ii) was granted prior to the date of Merger Agreement and was held by an employee of Southwestern or its Subsidiaries (as defined in the Merger Agreement) who was terminated upon or immediately after the Effective Time was automatically fully vested and payable in cash in an amount equal to $1.00 per unit granted under such performance cash unit award multiplied by the greater of (A) the percentage earned based on actual performance determined as of immediately prior to the Effective Time in accordance with the terms of the applicable award agreement and (B) 100%; and

each outstanding performance cash unit award of Southwestern that was granted pursuant to Southwestern’s 2022 Incentive Plan (other than those described above) was deemed earned at a level equal to $1.00 per unit granted under such performance cash unit award multiplied by the greater of (i) the percentage earned based on actual performance determined as of immediately prior to the Effective Time in accordance with the terms of the applicable award agreement and (ii) 100%. Such amount will vest and become payable in cash at the end of the original performance period associated with the corresponding performance cash unit award of Southwestern and was otherwise subject to and payable on the same terms and conditions (including “double-trigger” vesting provisions) as are set forth in the corresponding award agreement.
