     The consolidated financial results for the year ended December 31, 2010, reflect a 0.1 percent increase in total admissions and a 2.5 percent increase in total adjusted admissions compared with the same period in 2009. This increase was entirely due to acquisitions. On a same-store basis, admissions decreased 2.5 percent and adjusted admissions decreased 0.5 percent, compared with the same period in 2009. On a same-store basis, net operating revenues increased 3.9 percent, compared with the same period in 2009.

     Commenting on the results, Wayne T. Smith, chairman, president and chief executive officer of Community Health Systems, Inc., said, “The fourth quarter marked a very strong finish to 2010, as we reported the highest quarterly net operating revenues of the year. Our consistent pattern of growth reflects our success as an operator, especially in what has continued to be a challenging economic environment. For the year, net operating revenues increased by 7.3 percent for a record $13.0 billion, and net income was up by over 15 percent to $280.0 million, or $3.01 per diluted share, another record for Community Health Systems. This demonstrates that our centralized operating strategy has achieved favorable results across our markets as we have continued to focus on driving operating synergies at the individual hospital level, especially at our more recently acquired facilities.

     “We continued to expand our portfolio of hospitals in 2010 with a very selective acquisition strategy. We believe there are a growing number of independent hospitals that fit our criteria and can benefit from having a proven operator manage their facilities. With the ongoing uncertainties in the economy, and especially with respect to healthcare regulation, we believe there are even greater opportunities ahead for Community Health Systems to make suitable acquisitions. We can provide the experience and operating expertise with a proven track record as a valued partner in each of the communities we serve. As we look ahead to 2011, we will continue to deliver on our commitment of quality healthcare close to home,” Smith concluded.

     On December 9, 2010, the Company announced that it made an offer to acquire Tenet Healthcare Corporation (NYSE: THC) for $6.00 per share, including $5.00 per share in cash and $1.00 per share in Community Health Systems, Inc. common stock, which represented a premium of 40 percent over Tenet’s closing stock price on December 9, 2010. The total value of the transaction would be approximately $7.3 billion, including $3.3 billion of equity and approximately $4.0 billion of net debt. The offer was made in a letter to Tenet’s Board of Directors on November 12, 2010, and rejected by Tenet on December 6, 2010. On December 20, 2010, the Company announced its intention to nominate directors for election at the 2011 Annual Meeting of Tenet Healthcare Corporation, and on January 14, 2011, a full slate of 10 independent director nominees was nominated.

The following table provides information needed to calculate income per share which is adjusted for noncontrolling interests (in thousands).

		Three Months Ended								Year Ended

(b)

Continuing operating results exclude discontinued operations for the year ended December 31, 2009.

(c)

EBITDA consists of net income attributable to Community Health Systems, Inc. before interest, income taxes, and depreciation and amortization. Adjusted EBITDA is EBITDA adjusted to exclude discontinued operations, gain/loss from early extinguishment of debt and net income attributable to noncontrolling interests. The Company has from time to time sold noncontrolling interests in certain of its subsidiaries or acquired subsidiaries with existing noncontrolling interest ownership positions. The Company believes that it is useful to present adjusted EBITDA because it excludes the portion of EBITDA attributable to these third-party interests and clarifies for investors the Company’s portion of EBITDA generated by continuing operations. The Company uses adjusted EBITDA as a measure of liquidity. The Company has included this measure because it believes it provides investors with additional information about the Company’s ability to incur and service debt and make capital expenditures. Adjusted EBITDA is the basis for a key component in the determination of the Company’s compliance with some of the covenants under the Company’s senior secured credit facility, as well as to determine the interest rate and commitment fee payable under the senior secured credit facility.

Adjusted EBITDA is not a measurement of financial performance or liquidity under U.S. GAAP. It should not be considered in isolation or as a substitute for net income, operating income, cash flows from operating, investing or financing activities, or any other measure calculated in accordance with U.S. GAAP. The items excluded from adjusted EBITDA are significant components in understanding and evaluating financial performance and liquidity. This calculation of adjusted EBITDA may not be comparable to similarly titled measures reported by other companies.

The following table reconciles adjusted EBITDA, as defined, to net cash provided by operating activities as derived directly from the condensed consolidated financial statements (in thousands):

		Three Months Ended								Year Ended

		2010				2009				2010				2009

Net cash provided by operating activities		$	290,354			$	175,669			$	1,188,730			$	1,076,429

(d)		Included in income from continuing operations for the year ended December 31, 2009, is a gain from early extinguishment of debt of $2.4 million with an after-tax impact of $1.5 million related to the repurchases on the open market and cancellation of $126.5 million of Senior Notes and the early payment of $110.4 million of term loans under the Company’s Credit Facility.
(e)		Included in discontinued operations for the year ended December 31, 2009, is Presbyterian Hospital of Denton (255 licensed beds) located in Denton, Texas, which was conveyed to the noncontrolling partner on March 31, 2009.
(f)		Included in income from operations and income from continuing operations for the three months and year ended December 31, 2010, are the following non-same-store charges:

	•		Pre-tax charges of $4.5 million and $8.8 million, respectively, related to acquisition costs; and
	•		Pre-tax charges of $1.7 million and $6.7 million, respectively, for system conversion costs.

(g)

Total consolidated net operating revenues and operating costs and expenses for the three months and year ended December 31, 2010, includes net revenues of approximately $2.9 million and $20.0 million, respectively, and total operating costs and expenses of approximately $1.3 million and $8.8 million, respectively, relating to the California Department of Health’s enacted “California Hospital Fee Program”, which had been anticipated in 2010. These amounts represent the eighteen month retroactive impact of the program from its inception date through December 31, 2010. The State of California Department of Health Care Services issued a letter to the California Hospital Association stating that all necessary approvals for the California Hospital Fee Program were received during 2010, which is consistent with the Company’s revenue and expense recognition.

(h)

Income from continuing operations for the three months and year ended December 31, 2009, reflects the impact on earnings from the following recorded in the year ended December 31, 2009:

Regulation FD Disclosure

          The following tables set forth selected information concerning the Company’s projected consolidated operating results for the year ending December 31, 2011. These projections are based on the Company’s historical operating performance, current trends and other assumptions that the Company believes are reasonable at this time. The 2011 guidance reaffirms the Company’s previous annual earnings guidance for 2011 provided on October 27, 2010, as updated to reflect historical results through December 31, 2010, with certain additional detail provided and changes to the assumptions used in connection with the guidance. See page 15 for a list of factors that could affect the future results of the Company or the healthcare industry generally.

          The following is provided as guidance to analysts and investors:

		Updated 2011
		Projection
		Range
Net operating revenues (in millions)		$	13,900			to				$	14,200
Adjusted EBITDA (in millions)		$	1,850			to				$	1,875
Income from continuing operations per share — diluted		$	3.15			to				$	3.35
Same hospital annual admissions/adjusted admissions growth			-1.0	%		to					1.0	%
Weighted-average diluted shares (in millions)			92			to					93
Acquisitions of new hospitals			2			to					3
Income from continuing operations per share — diluted 1st Quarter ending March 31, 2011		$	0.77			to				$	0.80

The following assumptions were used in developing the 2011 guidance provided above:

•

The assumed acquisition of new hospitals for 2011 does not currently include the proposed Tenet acquisition.

•

Projected 2011 same hospital annual admissions/adjusted admissions growth does not take into account service closures and other unusual events.

•

Expressed as a percent of net operating revenues, the provision for bad debts is projected to be approximately 12.4% to 12.7% for 2011. These percentages may vary depending on changes in payor mix.

•

Expressed as a percent of net operating revenues, depreciation and amortization is projected to be approximately 4.7% to 4.8% for 2011; however, this is a fixed cost and the percentages may vary as revenue varies. Excludes possible impact of any future fair-value adjustments to investments and hospital fixed asset impairments.

•

2011 projection assumes an estimate of $0.03 to $0.06 per share (diluted) of acquisition costs that are required to be expensed. This projection excludes the estimated acquisition expense related to the proposed Tenet acquisition.

•		For the purpose of providing interest expense guidance, the Company assumes that the borrowing rate under the Company’s $7.2 billion Senior Secured Credit Facility for 2011 will remain relatively stable with the rates existing currently, particularly since the Company is a party to interest rate swap agreements (with original maturities of at least two years) resulting in total fixed debt including swaps being 93% of total debt. These swap agreements limit the effect of changes in interest rates. Based on these assumptions, expressed as a percentage of net operating revenues, interest expense is projected to be approximately 4.7% to 4.9% of net revenue guidance for 2011; however, these percentages will vary as revenue and interest rates vary. The 2011 projections do not assume any changes to the financing terms of the Senior Secured Credit Facility or any new financing arrangements, which have not been previously announced.
•		On September 15, 2010, the Company adopted a new open market repurchase program for up to four million shares of the Company’s common stock, not to exceed $100 million in purchases. The new repurchase program will conclude at the earliest of three years, when the maximum number of shares has been repurchased or when the maximum dollar amount has been reached. Through February 24, 2011, approximately 451,000 shares with a value of approximately $13.9 million were purchased and retired under this repurchase plan.

•

Expressed as a percentage of net operating revenues, equity in earnings of unconsolidated affiliates is projected to be approximately 0.3% to 0.4% for 2011.

•

Expressed as a percentage of net operating revenues, net income attributable to noncontrolling interests is projected to be approximately 0.5% to 0.6% for 2011.

•

Expressed as a percentage of income from continuing operations before income taxes, provision for income tax is projected to be approximately 31.0% to 33.0% for 2011.

•

Capital expenditures are projected as follows (in millions):

		2011
		Guidance
Total		$	750			to				$	850

•		Regarding meaningful use certified electronic health records incentive payments, no significant benefit is currently projected for 2011. This will be updated as the year progresses.
•		Net cash provided by operating activities are projected as follows (in millions):

		2011
		Guidance
Total		$	1,150			to				$	1,250

•

The Company’s guidance does not take into account resolution of certain pending government investigations and lawsuits.

     The projections set forth in this report constitute forward-looking statements within the meaning of Section 27A of the Securities Act, Section 21E of the Exchange Act and the Private Securities Litigation Reform Act of 1995. Although the Company believes that these forward-looking statements are based on reasonable assumptions, these assumptions are inherently subject to significant economic and competitive uncertainties and contingencies, which are difficult or impossible to predict accurately and are beyond the control of the Company. Accordingly, the Company cannot give any assurance that its expectations will in fact occur and cautions that actual results may differ materially from those in the forward-looking statements. A number of factors could affect the future results of the Company or the healthcare industry generally and could cause the Company’s expected results to differ materially from those expressed in this filing.

These factors include, among other things:

	•		general economic and business conditions, both nationally and in the regions in which we operate;
	•		implementation and effect of potential and recently-adopted federal and state healthcare legislation;
	•		risks associated with our substantial indebtedness, leverage, and debt service obligations;
	•		demographic changes;
	•		changes in, or the failure to comply with, governmental regulations;
	•		potential adverse impact of known and unknown government investigations, audits, and Federal and State False Claims Act litigation;
	•		our ability, where appropriate, to enter into and maintain managed care provider arrangements and the terms of these arrangements;
	•		changes in, or the failure to comply with, managed care provider contracts could result in disputes and changes in reimbursement that could be applied retroactively;
	•		changes in inpatient or outpatient Medicare and Medicaid payment levels;
	•		increases in the amount and risk of collectability of patient accounts receivable;
	•		increases in wages as a result of inflation or competition for highly technical positions and rising supply costs due to market pressure from pharmaceutical companies and new product releases;
	•		liabilities and other claims asserted against us, including self-insured malpractice claims;
	•		competition;
	•		our ability to attract and retain, without significant employment costs, qualified personnel, key management, physicians, nurses and other health care workers;
	•		trends toward treatment of patients in less acute or specialty healthcare settings, including ambulatory surgery centers or specialty hospitals;
	•		changes in medical or other technology;
	•		changes in U.S. generally accepted accounting principles;
	•		the availability and terms of capital to fund additional acquisitions or replacement facilities;
	•		our ability to successfully acquire additional hospitals;
	•		our ability to successfully integrate any acquired hospitals or to recognize expected synergies from such acquisitions;
	•		our ability to obtain adequate levels of general and professional liability insurance;
	•		timeliness of reimbursement payments received under government programs; and
	•		the other risk factors set forth in our public filings with the Securities and Exchange Commission.

     The consolidated operating results for the three months and year ended December 31, 2010, are not necessarily indicative of the results that may be experienced for any such future period or for any future year, including the full year of 2011.

     The Company cautions that the projections for calendar year 2011 set forth in this press release are given as of the date hereof based on currently available information. The Company is not undertaking any obligation to update these projections as conditions change or other information becomes available.
