ITEM 12.    Results of Operations And Financial Condition.

        The following information is being furnished pursuant to Item 12, "Results of Operations and Financial Condition." Consequently, it is not deemed "filed" for the purposes of Section 18 of the Securities Exchange Act of 1934 (the "Exchange Act"), or otherwise subject to the liabilities of that section. It may only be incorporated by reference in another filing under the Exchange Act or Securities Act of 1933 if such subsequent filing specifically references this Form 8-K. On October 23, 2003, Community Health Systems, Inc. (the "Company"), announced operating results for the quarter ended September 30, 2003. A copy of the related press release is attached as Exhibit 99.1 to this Form 8-K.

        The following table sets forth selected information concerning the projected consolidated operating results of the Company for the years ending December 31, 2003 and 2004. 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 following is provided as guidance to analysts and investors:

 
  2004
Projection Range

  2003 Projection Range
  2002 Actual
Net operating revenue (in millions)   $3,275 to $3,325   $2,775 to $2,800   $2,200
Net income per share—diluted   $1.46 to $1.49 *   $1.27 *   $1.00 **
Same-Store annual admissions growth   1.0% to 3.0%   0.0% to 1.0%   4.4%
Weighted average diluted shares (in millions)   109 *   108 *    
Acquisitions of new hospitals   2–4        

*
The inclusion of the assumed conversion of convertible notes for purposes of fully diluted calculation is expected to cause a $0.04 actual decrease in the reported net income per share in 2004 and $0.01 actual decrease in 2003. Accordingly, for purposes of providing guidance, we have assumed the conversion of the convertible notes (after tax interest savings of $8.7 million and 8.6 million shares added to the number of weighted average diluted shares).

**
To conform to the requirements of SFAS No. 145, the extraordinary loss from early extinguishment of debt has been reclassified to operating income. Had income before extraordinary item per share been shown for 2002 as previously reported, income per share before extraordinary item diluted would have been $1.05.

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

  2004
  2003
Equipment and renovations   $ 132 to $135   $ 102 to $104
Replacement hospitals   $ 14 to $15   $ 42 to $44
   
 
Projected total   $ 146 to $150   $ 144 to $148
   
 

        The projections set forth in this report constitute forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, Section 21E of the Securities Exchange Act of 1934 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:

        The consolidated operating results for the third quarter and nine months ended September 30, 2003, are not necessarily indicative of the results that may be experienced for any future quarter or for any future fiscal year, including this fiscal year.

        The Company cautions that the annual projections for 2003 and 2004 set forth herein are given as of the date hereof based on currently available information. The Company is not undertaking any obligations to update these projections as conditions change or other information becomes available.
