2014 Guidance

The Company on July 16, 2014 updated its previously issued financial guidance ranges for 2014.

The revised guidance assumes a benefit to Adjusted EBITDA from the Patient Protection and Affordable Care Act (Health Reform Law) in 2014 of approximately 2 to 3 percent of Adjusted EBITDA (original guidance was 1 to 2 percent), and the second quarter Medicaid revenues from the indigent care component of the Texas Medicaid Waiver Program. Both the original and revised guidance also include estimated electronic health record incentive income assumptions in a range of $110-$130 million and EHR expenses in a range of $110-$130 million. The guidance reflects estimated increases in share-based compensation expense to approximately $160 million (original guidance was $168 million), from $113 million in 2013. Guidance excludes the impact of items, if applicable, that are non-operational in nature including items such as, but not limited to, gains or losses on sales of facilities and businesses, gains or losses on early debt retirement and impairments of long-lived assets. This guidance is also subject to certain risks including those as set forth below in the Company’s “Forward-Looking Statements”.

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, losses on retirement of debt and legal claim costs, 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, losses on retirement of debt and legal claim costs 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 on sales of facilities, losses on retirement of debt and legal claim costs, 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, losses on retirement of debt and legal claim costs, 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, losses on retirement of debt and legal claim costs, and Adjusted EBITDA, as presented, may not be comparable to other similarly titled measures presented by other companies.
