COMMUNITY HEALTH SYSTEMS, INC. PREVIEWS SECOND QUARTER OPERATING RESULTS

FRANKLIN, Tenn. (July 18, 2013) - Community Health Systems, Inc. (NYSE: CYH) (the “Company”) today announced preliminary financial and operating results for the three months ended June 30, 2013. The financial results are subject to finalization of the Company’s quarterly financial and accounting procedures.

The Company anticipates net operating revenues for the three months ended June 30, 2013, will be approximately $3.236 billion, compared with $3.243 billion for the same period in 2012. Income before taxes for the three months ended June 30, 2013, is expected to be approximately $65 million, compared with $151.7 million for the three months ended June 30, 2012. Adjusted EBITDA for the three months ended June 30, 2013, is expected to be approximately $414 million, compared with $483 million for the same period in 2012. Adjusted EBITDA is EBITDA adjusted to exclude discontinued operations, loss from early extinguishment of debt, and net income attributable to non-controlling interests. The Company uses adjusted EBITDA as a measure of liquidity. Net cash provided by operating activities for the three months ended June 30, 2013, is expected to be approximately $250 million, compared with $295.6 million for the same period in 2012.

The consolidated operating results for the three months ended June 30, 2013, reflect a 5.1 percent decrease in total admissions and a 1.8 percent decrease in adjusted admissions compared with the same period in 2012. On a same-store basis, admissions decreased 5.7 percent while adjusted admissions decreased 2.6 percent compared with the same period in 2012.

Weakness in volume, most significantly in May and June, coupled with higher-than-anticipated bad debts and a deterioration in payor mix resulted in lower-than-anticipated net operating revenues during the period. This is the Company’s first significant earnings miss since the third quarter of 2006. In response, our management team has intensified its focus on core operating strategies, volume initiatives and expense management.

The Company also announced that the Department of Justice’s investigation of Medicare short-stay admissions from emergency departments continues. The Company has met with the government twice this year to review and discuss the status of the investigation, the potential theories and defenses, and the results of its joint medical necessity review. On July 9, 2013, shortly after a second meeting with the government, the Company was served with an additional document subpoena, which seeks additional documents related to the admission of inpatients from its emergency departments, as well as documents that support the factual refutations and defenses that the Company has articulated during its discussions with the government. Many of the categories of documents were the same as those requested in the April 2011 subpoena, but the request is being broadened to additional custodians and locations; additional categories of documents have been added that appear to be related to the same general topic of investigation (for example, documentation is requested regarding observation criteria and financial relationships with physicians who have admitting privileges at the Company’s hospitals). The government also served civil investigative demands to interview two of the Company’s current employees, one division president and one senior vice president. The Company will continue to cooperate with the government in their investigative efforts.

The Company anticipates reporting its complete financial results for the three and six months ended June 30, 2013, on July 29, 2013, followed by a live earnings call on July 30, 2013.
