COMMUNITY HEALTH SYSTEMS, INC. ANNOUNCES

AMENDMENTS TO ACCOUNTS RECEIVABLE SECURITIZATION PROGRAM

TO INCREASE AVAILABILITY TO $700 MILLION

FRANKLIN, Tenn. (March 31, 2014) — Community Health Systems, Inc. (the “Company”) (NYSE: CYH) announced today that its wholly owned subsidiary, CHS/Community Health Systems, Inc. (“CHS”), and certain of CHS’ subsidiaries have entered into amendments to its accounts receivable securitization program (the “Receivables Facility”) with a group of conduit lenders and liquidity banks (the “Lenders”) that increase the size of the Receivables Facility from $500 million to $700 million. Crédit Agricole Corporate and Investment Bank will continue to serve as managing agent and the administrative agent and The Bank of Nova Scotia and The Bank of Tokyo-Mitsubishi UFJ, Ltd. will also continue to serve as managing agents. During the term of the Receivables Facility, these subsidiaries of CHS, including additional subsidiaries that were not previously a party to the Receivables Facility, sell certain of their existing and future accounts receivable (the “Receivables”) to CHS, which then sells or contributes the Receivables to CHS Receivables Funding, LLC, a bankruptcy-remote, special-purpose limited liability company. CHS Receivables Funding, LLC in turn grants security interests in the Receivables to Crédit Agricole Corporate and Investment Bank in exchange for borrowings from the Lenders of up to $700 million outstanding from time to time based on the availability of eligible Receivables and other customary factors. Unless earlier terminated or subsequently extended pursuant to its terms, the Receivables Facility will expire on March 21, 2016, subject to customary termination events that could cause an early termination date.

The amendment to the Receivables Facility will be more fully described in, and the principal agreements amending the program will be filed as exhibits to, a Current Report on Form 8-K to be filed with the Securities and Exchange Commission.
