Operating Results Summary

(Dollars in millions, except per share amounts)

Management and investors review both the overall performance (including; net income attributable to HCA Holdings, Inc., excluding losses (gains) on sales of facilities and loss on retirement of debt and GAAP net income attributable to HCA Holdings, Inc.) and operating performance (Adjusted EBITDA) of our health care facilities. Adjusted EBITDA and the Adjusted EBITDA margin (Adjusted EBITDA divided by revenues) are utilized by management and investors to compare our current operating results with the corresponding periods during the previous year and to compare our operating results with other companies in the health care industry. It is reasonable to expect that losses (gains) on sales of facilities and losses on retirement of debt will occur in future periods, but the amounts recognized can vary significantly from period to period, do not directly relate to the ongoing operations of our health care facilities and complicate period comparisons of our results of operations and operations comparisons with other health care companies.

Net income attributable to HCA Holdings, Inc., excluding losses (gains) on sales of facilities and loss on retirement of debt and Adjusted EBITDA are not measures of financial performance under GAAP, and should not be considered as alternatives to net income attributable to HCA Holdings, Inc. as a measure of operating performance or cash flows from operating, investing and financing activities as a measure of liquidity. Because net income attributable to HCA Holdings, Inc., excluding losses (gains) on sales of facilities and loss on retirement of debt and Adjusted EBITDA are not measurements determined in accordance with GAAP and are susceptible to varying calculations, net income attributable to HCA Holdings, Inc., excluding losses (gains) on sales of facilities and loss on retirement of debt and Adjusted EBITDA, as presented, may not be comparable to other similarly titled measures presented by other companies.
