Item 8.01

Other Events.

As previously disclosed, on January 10, 2024, Southwestern Energy Company, a Delaware corporation (NYSE: SWN) (“Southwestern”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Chesapeake Energy Corporation, an Oklahoma corporation (NASDAQ: CHK) (“Chesapeake”), Hulk Merger Sub, Inc., a Delaware corporation and a newly formed, wholly-owned subsidiary of Chesapeake (“Merger Sub”) and Hulk LLC Sub, LLC, a Delaware limited liability company and a wholly owned subsidiary of Chesapeake (“LLC Sub” and together with Merger Sub, Southwestern and Chesapeake, the “Parties”). Subject to the terms and conditions set forth in the Merger Agreement, Merger Sub will be merged with and into Southwestern, with Southwestern continuing as the surviving entity and a wholly-owned subsidiary of Chesapeake (the “Merger”).

On February 29, 2024, Chesapeake filed a registration statement on Form S-4 (No. 333-277555) (the “Registration Statement”), which contained a preliminary prospectus of Chesapeake and a preliminary joint proxy statement of Southwestern and Chesapeake. The Registration Statement was declared effective by the Securities and Exchange Commission (the “SEC”) on May 17, 2024, which contained Chesapeake’s definitive prospectus and Southwestern’s and Chesapeake’s definitive joint proxy statement (the “joint proxy statement/prospectus”). Chesapeake filed the joint proxy statement/prospectus with the SEC on May 17, 2024 and Southwestern commenced mailing copies of the joint proxy statement/prospectus on or about May 17, 2024.

Since entering into the Merger Agreement, Southwestern has received, to its knowledge, seven demand letters from purported stockholders of Southwestern and one demand for books and records under Section 220 of the General Corporation Law of the State of Delaware (the books and records demand together with the demand letters, the “Demand Letters”). Three complaints have been filed against Southwestern in New York Supreme Court, asserting claims for negligence, negligent misrepresentation, and breaches of fiduciary duties stemming from allegedly material omissions in the joint proxy statement/prospectus (the “Complaints”). The Demand Letters assert that purported material information is omitted from the joint proxy statement/prospectus. It is possible that additional, or similar demand letters may be received by Southwestern, or that complaints making similar allegations may be filed naming Southwestern as a defendant, regarding the Merger. Absent new or different allegations that are material or a disclosure obligation under the U.S. federal securities laws, Southwestern will not necessarily disclose such additional demands or complaints.

Southwestern believes that the disclosures set forth in the joint proxy statement/prospectus comply fully with applicable law and exchange rules, that no further disclosure beyond that already contained in the joint proxy statement/prospectus is required under applicable law or exchange rules, and that the allegations asserted in the Demand Letters are entirely without merit. However, in order to moot these disclosure claims, to avoid nuisance, cost and distraction, and to preclude any efforts to delay the closing of the Merger, and without admitting any culpability, liability or wrongdoing and without admitting the relevance or materiality of such disclosures, Southwestern is voluntarily supplementing the joint proxy statement/prospectus with the supplemental disclosures set forth below (the “Supplemental Disclosures”). Nothing in the Supplemental Disclosures shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, Southwestern specifically denies all allegations in the Demand Letters or the Complaints that any additional disclosure was or is required.

SUPPLEMENTAL DISCLOSURES TO JOINT PROXY STATEMENT/PROSPECTUS

The following supplemental information should be read in conjunction with the joint proxy statement/prospectus, which should be read in its entirety and is available on the SEC’s website at http://www.sec.gov, along with periodic reports and other information Southwestern files with the SEC. To the extent that the information set forth herein differs from or updates information contained in the joint proxy statement/prospectus, the information set forth herein shall supersede or supplement the information in the joint proxy statement/prospectus. All page references are to pages in the joint proxy statement/prospectus, and terms used below, unless otherwise defined, have the meanings set forth in the joint proxy statement/prospectus.

The disclosure under the heading “The Merger—Background of the Merger” is hereby supplemented by amending and restating the second full paragraph on page 90 of the joint proxy statement/prospectus as follows:

At a regularly scheduled meeting of the Southwestern Board on August 1, 2023, at which all members were present, Mr. Way provided an update regarding the potential business combination with Chesapeake, noting that there had been no further discussion with Chesapeake since May 2023, and discussed the relative financial performance of Southwestern and Chesapeake. Mr. Way also discussed a potential strategic transaction with Company B, noting that Southwestern and Company B had executed a confidentiality agreement. The confidentiality agreement did not contain a standstill provision limiting Company B from making a topping bid after the Merger was announced and did not include a standstill provision with a “don’t ask, don’t waive” provision. The Board noted that any potential transaction with Company B would have to be evaluated in connection with a review of strategic alternatives, including a potential transaction with Chesapeake.

The disclosure under the heading “The Merger—Background of the Merger” is hereby supplemented by amending and restating the seventh full paragraph on page 91 of the joint proxy statement/prospectus as follows:

On September 20, 2023, certain members of the executive management of Southwestern, including Messrs. Way, Carrell, and Giesler, and representatives of Wells Fargo Securities, LLC (“Wells Fargo”) attended a management presentation regarding a potential strategic transaction with a third potential counterparty (“Company C”) and received access to certain confidential information regarding Company C and its business. The confidentiality agreement entered into between Southwestern and Company C did not contain a standstill provision limiting Company C from making a topping bid after the Merger was announced and did not include a standstill provision with a “don’t ask, don’t waive” provision.

The disclosure under the heading “The Merger—Background of the Merger” is hereby supplemented by amending and restating the third full paragraph on page 95 of the joint proxy statement/prospectus as follows:

On December 1, 2023, Mr. Dell’Osso called Mr. Way and stated that Chesapeake was not prepared to increase its prior exchange ratio proposal at that time. However, Mr. Dell’Osso sought to continue the prior discussions regarding value and various other issues. Consistent with the Southwestern Board’s instructions to continue to progress such negotiations, Mr. Way further discussed with Mr. Dell’Osso such issues, including the construct for identifying and selecting employees for the combined company, the name of the combined company, and the role of Southwestern’s corporate office for the combined company. Mr. Dell’Osso and Mr. Way did not discuss specifics related to executive or director employment or compensation matters as it related to post-closing operations during this phone call or in any subsequent discussion and only discussed a framework and construct for identifying and selecting employees. The parties agreed to resolve any post-closing employment and compensation matters in the interim period between signing the Merger Agreement and Closing. No other proposals or indications of interest from any other parties with which Southwestern had discussions included any details concerning the retention of Southwestern management in the post-closing company or the purchase of or participation by employees of Southwestern in the equity of the combined company following the completion of the Proposed Transaction.

The disclosure under the heading “The Merger” is hereby supplemented by inserting the following disclosure after the second full paragraph on page 101 of the joint proxy statement/prospectus:

The disclosure on page 113 of the joint proxy statement/prospectus is hereby supplemented by amending and restating the first paragraph set forth under “The Merger—Certain Unaudited Forecasted Financial Information—Southwestern Management Synergies Estimates” as follows:

For purposes of the Southwestern Management Synergies Estimates, Southwestern management estimated operating synergies at $86 million in 2024, $173 million in 2025 and $288 million in 2026 and 2027, and estimated capital synergies of $258 million in 2024, $236 million in 2025, $200 million in 2026 and $143 million in 2027. No value was attributed to net operating loss carryforwards and tax credits for purposes of the Southwestern Management Synergies Estimates and no value in respect of such net operating loss carryforwards and tax credits was included in the “Projections” as utilized by Goldman Sachs in connection with its opinion. The Southwestern Management Synergies Estimates were based on certain assumptions regarding the types of synergies that may be achieved in connection with the Merger, as well as the timing to achieve such synergies, including the following assumptions:

reduction of general and administrative costs from duplicative public company and other overhead costs;

reduction in well costs achieved by combined best practice and schedule optimization;

savings on capital expenditures per well attributable to the use of extended laterals; and

reduction of operating costs as a result of infrastructure optimization and improved water utilization.

The disclosure on pages 127-128 of the joint proxy statement/prospectus are hereby supplemented by amending and restating the first and second full paragraphs set forth under “The Merger—Opinion of Southwestern’s Financial Advisor—Summary of Financial Analyses—Illustrative Discount Cash Flow Analysis — Southwestern Standalone” as follows:

Using the Southwestern Projections, Goldman Sachs performed an illustrative discounted cash flow analysis on Southwestern to derive a range of illustrative present values per share of Southwestern Common Stock. Using the mid-year convention for discounting cash flows and discount rates ranging from 9.0% to 11.0%, reflecting estimates of Southwestern’s weighted average cost of capital, Goldman Sachs discounted to present value as of September 30, 2023, (i) estimates of unlevered free cash flow for Southwestern for the period from October 1, 2023, to December 31, 2027, as reflected in the Southwestern Projections and (ii) a range of illustrative terminal values for Southwestern, which were calculated by applying terminal year exit EBITDA multiples ranging from 3.25x to 4.25x, to a terminal year estimate of EBITDA to be generated by Southwestern in calendar year 2027 of approximately $3.244 billion, as reflected in the Southwestern Projections (which analysis implied perpetuity growth rates ranging from 0.6% to 4.3%). The range of terminal year exit EBITDA multiples was estimated by Goldman Sachs utilizing its professional judgment and experience, taking into account historical trading multiples of Southwestern. Goldman Sachs derived such discount rates by application of the Capital Asset Pricing Model (“CAPM”), which requires certain company-specific inputs, including Southwestern’s target capital structure weightings, the cost of long-term debt, after-tax yield on permanent excess cash, if any, future applicable marginal cash tax rate and a beta for Southwestern, as well as certain financial metrics for the United States financial markets generally.\

Goldman Sachs derived a range of illustrative enterprise values for Southwestern by adding the ranges of present values it derived above. Goldman Sachs then subtracted from the range of illustrative enterprise values it derived for Southwestern the amount of Southwestern’s net debt (including amounts attributable to liability classified equity awards) of approximately $4.167 billion as of September 30, 2023, as approved for Goldman Sachs’ use by Southwestern, to derive a range of illustrative equity values for Southwestern. Goldman Sachs then divided the range of illustrative equity values it derived by the number of fully diluted outstanding shares of Southwestern of approximately 1.109 billion as of September 30, 2023, as provided by and approved for Goldman Sachs’ use by Southwestern, using the treasury stock method, to derive a range of illustrative present values per share ranging from $4.01 to $6.60.

The disclosure on page 128 of the joint proxy statement/prospectus is hereby supplemented by amending and restating the first and second full paragraph set forth under “The Merger—Opinion of Southwestern’s Financial Advisor—Summary of Financial Analyses—Illustrative Present Value of Future Share Price Analysis — Southwestern Standalone” as follows:

Using the Southwestern Projections, Goldman Sachs performed an illustrative analysis of the implied present value of an illustrative future value per share of Southwestern Common Stock. For this analysis, Goldman Sachs first calculated the implied enterprise value for Southwestern of approximately $11.917 billion as of December 31 for the fiscal year 2025, by applying a range of exit multiples of illustrative enterprise value (“EV”) to next twelve month (“NTM”) EBITDA (“EV/NTM EBITDA”) of 3.25x to 4.25x to estimates of Southwestern’s NTM EBITDA. This illustrative range of EV/NTM EBITDA exit multiple estimates was derived by Goldman Sachs utilizing its professional judgment and experience, taking into account current and historical EV/NTM EBITDA exit multiples for Southwestern.

Goldman Sachs then subtracted the amount of Southwestern’s net debt (including amounts attributable to liability classified equity awards) of approximately $3.884 billion for fiscal year 2025, as provided by and approved for Goldman Sachs’ use by Southwestern, from the respective implied enterprise values in order to derive a range of illustrative equity values as of December 31 for Southwestern for the fiscal year 2025. Goldman Sachs then divided these implied equity values by the projected year-end number of fully diluted outstanding shares of Southwestern Common Stock of the fiscal year 2025 of approximately 1.119 billion for the fiscal year 2025, calculated using information provided by and approved for Goldman Sachs’ use by Southwestern, to derive a range of implied future values per share of Southwestern Common Stock. Goldman Sachs then discounted these implied future equity values per share of Southwestern Common Stock to September 30, 2023 using an illustrative discount rate of 11.8%, reflecting an estimate of Southwestern’s cost of equity. Goldman Sachs derived such discount rate by application of the CAPM, which requires certain company-specific inputs, including a beta for Southwestern, as well as certain financial metrics for the United States financial markets generally. This analysis resulted in a range of implied present values of $4.48 to $6.69 per share of Southwestern Common Stock.

The disclosure on page 129 of the joint proxy statement/prospectus is hereby supplemented by amending and restating the table set forth under “The Merger—Opinion of Southwestern’s Financial Advisor—Summary of Financial Analyses—Selected Precedent Transactions Premia Analysis” as follows:

The disclosure on pages 129-130 of the joint proxy statement/prospectus is hereby supplemented by amending and restating the first and second full paragraphs set forth under “The Merger—Opinion of Southwestern’s Financial Advisor—Summary of Financial Analyses—Illustrative Discounted Cash Flow Analysis — Pro Forma Combined Company” as follows:

Using the Southwestern Projections, which take into account the Southwestern Projections Synergies, Goldman Sachs performed an illustrative discounted cash flow analysis of the combined company on a pro forma basis. Using the mid-year convention for discounting cash flows and discount rates ranging from 8.5% to 10.5%, reflecting estimates of the combined company’s weighted average cost of capital, Goldman Sachs discounted to present value as of September 30, 2023 (i) estimates of unlevered free cash flow for the pro forma combined company for the period from October 1, 2023, to December 31, 2027, as reflected in the Southwestern Projections and (ii) a range of illustrative terminal values for the pro forma combined company, which were calculated by applying terminal year exit EBITDA multiples ranging from 4.0x to 5.0x, to a terminal year estimate of the EBITDA to be generated by the pro forma combined company of approximately $6.565 billion, as reflected in the Southwestern Projections (which analysis implied perpetuity growth rates of (1.0)% to 2.6% and includes run-rate Southwestern Projections Synergies). The range of terminal year exit EBITDA multiples was estimated by Goldman Sachs utilizing its professional judgment and experience, taking into account historical trading multiples of Southwestern and Chesapeake over certain prior periods. Goldman Sachs derived such discount rates by application of the CAPM, which requires certain company-specific inputs, including the pro forma combined company’s target capital structure weightings, the cost of long-term debt, after-tax yield on permanent excess cash, if any, future applicable marginal cash tax rate and a beta for the pro forma combined company, as well as certain financial metrics for the United States financial markets generally.

Goldman Sachs derived ranges of illustrative pro forma enterprise values for the combined company by adding the ranges of present values it derived above. Goldman Sachs then subtracted from the range of illustrative pro forma enterprise values the amount of pro forma combined company net debt (including amounts attributable to liability classified equity awards) of approximately $5.223 billion as of September 30, 2023, as provided by and approved for Goldman Sachs’ use by Southwestern, to derive a range of implied pro forma equity values for the combined company. Goldman Sachs then divided the range of implied pro forma equity values it derived by the number of pro forma fully diluted shares of combined Southwestern common stock (referred to in this section as the “Combined Southwestern Common Stock”) expected to be outstanding following the consummation of the transaction of approximately 240.9 million, as of September 30, 2023, as provided by and approved for Goldman Sachs’ use by Southwestern, using the treasury stock method. Lastly, Goldman Sachs multiplied such amount by the Exchange Ratio of 0.0867x to derive a range of illustrative present values per share of the combined company. This analysis resulted in a range of implied present values of $6.55 to $8.78 per share of Combined Southwestern Common Stock.

The disclosure on page 130 of the joint proxy statement/prospectus is hereby supplemented by amending and restating the second and third full paragraphs set forth under “The Merger—Opinion of Southwestern’s Financial Advisor—Summary of Financial Analyses— Illustrative Present Value of Future Share Price Analysis — Pro Forma Combined Company” as follows:

Using the Southwestern Projections, which take into account the Southwestern Projections Synergies, Goldman Sachs performed an illustrative analysis of the implied present value of a share of Combined Southwestern Common Stock. For this analysis, Goldman Sachs first calculated the illustrative pro forma enterprise value of approximately $28.578 billion as of December 31 for fiscal year 2025, by applying a range of exit multiples of EV/NTM EBITDA of 4.0x to 5.0x to estimates of pro forma NTM EBITDA for the fiscal year 2025. This illustrative range of EV/NTM EBITDA exit multiple estimates was derived by Goldman Sachs utilizing its professional judgment and experience, taking into account current and historical EV/NTM EBITDA exit multiples for Southwestern and Chesapeake over certain periods.

Goldman Sachs then subtracted the amount of the combined company’s net debt (including amounts attributable to liability classified equity awards) of approximately $5.327 billion for the fiscal year 2025, as provided by and approved for Goldman Sachs’ use by Southwestern, from the respective illustrative pro forma enterprise values in order to derive a range of implied pro forma equity values as of December 31 for the fiscal year 2025. Goldman Sachs then divided these implied pro forma equity values by the projected year-end number of shares of Combined Southwestern Common Stock for the fiscal year 2025 of approximately 232 million, calculated using information provided by and approved for Goldman Sachs’ use by Southwestern, to derive a range of implied pro forma future values per share of Combined Southwestern Common Stock (excluding dividends). By applying an illustrative pro forma discount rate of 10.9%, reflecting an estimate of the combined company’s cost of equity, and for the dividends only, using a mid-year convention, Goldman Sachs discounted these implied pro forma future equity values per share of Combined Southwestern Common Stock to September 30, 2023. Goldman Sachs derived such discount rate by application of the CAPM, which requires certain company-specific inputs, including a beta for the combined company, as well as certain financial metrics for the United States financial markets generally. Goldman Sachs then added the cumulative pro forma dividends per share for the fiscal year 2025 projected to be paid to combined company’s stockholders, discounted to September 30, 2023, to derive a range of implied pro forma future values per share of Combined Southwestern Common Stock (including dividends). Lastly, Goldman Sachs multiplied such amount by the Exchange Ratio of 0.0867x to derive a range of implied pro forma present values per share of the combined company. This analysis resulted in a range of implied present values of $6.44 to $8.28 per share of Combined Southwestern Common Stock.
