COMMUNITY HEALTH SYSTEMS, INC.

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

On April 18, 2024, certain subsidiaries of the Company (the “CHS Selling Entities”) entered into a definitive asset purchase agreement, as amended (the “Purchase Agreement”), with Hamilton Health Care System, Inc. and certain of its affiliates (collectively, “Purchaser”), providing for the sale of substantially all of the assets, and the assumption of certain liabilities, related to the general acute care hospital known as Tennova Healthcare – Cleveland, together with certain related businesses (collectively, the “Facilities”), located in Cleveland, Tennessee (the transactions contemplated by the Purchase Agreement, the “Transactions”). On August 1, 2024, the Transactions were completed pursuant to the terms of the Purchase Agreement. The base purchase price paid to the Company in connection with the Transactions at a preliminary closing on July 31, 2024, after giving effect to estimated working capital and purchase price adjustments, was approximately $160 million in cash (subject to a post-closing working capital adjustment). In addition to the base purchase price set forth above, the Purchase Agreement provides that the Purchaser is required to pay additional cash consideration to the CHS Selling Entities following the closing of the Transactions in an amount, if any, to be determined based on additional supplemental payments that may be realized by the Purchaser and the Facilities following the closing of the Transactions as a result of the potential modification to supplemental reimbursement programs as more specifically provided in the Purchase Agreement. The base purchase price received by the CHS Selling Entities as noted above at the preliminary closing on July 31, 2024, did not include any additional cash consideration that the Company may receive contingent upon such potential modifications to certain supplemental reimbursement programs in accordance with the terms of the Purchase Agreement.

The Company has determined that the operations of the Facilities that was divested in the Transactions do not meet the definition of discontinued operations pursuant to Financial Accountings Standards Board Accounting Standards Codification 205 (ASC 205), “Presentation of Financial Statements.”

The accompanying unaudited pro forma condensed consolidated balance sheet of the Company is presented as if the Transactions had occurred as of June 30, 2024. The estimated gain/(loss) on sale in connection with the Transactions is reflected in the unaudited pro forma condensed balance sheet within retained earnings.

The accompanying unaudited pro forma condensed consolidated statements of loss for the six months ended June 30, 2024 and the year ended December 31, 2023 (collectively the “Pro Forma Periods”) include certain pro forma adjustments to illustrate the estimated effect of the Company’s disposition, as if the Transactions had occurred on January 1, 2023. The amounts included in the historical columns represent the Company’s historical balance sheet and statements of loss for the respective Pro Forma Periods presented.

The accompanying unaudited pro forma condensed consolidated financial statements have been prepared in accordance with Article 11 of Regulation S-X and do not include all of the information and note disclosures required by generally accepted accounting principles of the United States (“GAAP”). Pro forma financial information is intended to provide information about the continuing impact of a transaction by showing how a specific transaction might have affected historical financial statements. Pro forma financial information illustrates only the isolated and objectively measurable (based on historically determined amounts) effects of a particular transaction, and excludes effects based on judgmental estimates of how historical management practices and operating decisions may or may not have changed as a result of the transaction. Therefore, pro forma financial information does not include information about the possible or expected impact of current actions taken by management in response to the Transactions, as if management’s actions were carried out in previous reporting periods.

The unaudited pro forma condensed consolidated financial information is subject to the assumptions and adjustments described in the accompanying notes. These assumptions and adjustments are based on information presently available. Actual adjustments may differ materially from the information presented. The unaudited pro forma condensed consolidated financial statements are based on the historical financial statements of the Company for each period presented and in the opinion of the Company’s management, all adjustments and disclosures necessary for a fair presentation of the pro forma data have been made. These unaudited pro forma condensed consolidated financial statements are presented for illustrative purposes only and are not necessarily indicative of the results of operations or financial condition that would have been achieved had events reflected been completed as of the dates indicated, and may

not be useful in predicting the impact of the Transactions on the future financial condition and results of operations of the Company due to a variety of factors. These unaudited pro forma condensed consolidated financial statements and the notes thereto should be read in conjunction with the Company’s financial statements for the three and six months ended June 30, 2024, included in the Company’s Quarterly Report on Form 10-Q filed on July 25, 2024, and the Company’s financial statements for the year ended December 31, 2023, included in the Company’s Annual Report on Form 10-K filed on February 21, 2024.
