Select Medical Holdings Corporation Announces Results for

First Quarter Ended March 31, 2014 and Cash Dividend

MECHANICSBURG, PENNSYLVANIA — May 1, 2014 — Select Medical Holdings Corporation (“Select Medical”) (NYSE: SEM) today announced results for its quarter ended March 31, 2014 and the declaration of a cash dividend.

For the quarter ended March 31, 2014, net operating revenues increased 1.7% to $762.6 million, compared to $750.0 million for the same quarter, prior year.  The results for the quarter ended March 31, 2014 reflect Medicare changes that became effective on April 1, 2013, including (i) a 2% reduction in Medicare payments that was implemented as part of the automatic reduction in federal spending mandated under the Budget Control Act of 2011 (the “Sequestration Reduction”), and (ii) an increase from 25% to 50% in the multiple procedure payment reduction for therapy services as mandated by the American Taxpayer Relief Act of 2012 (the “MPPR Reduction”).  For the quarter ended March 31, 2014, these changes reduced both net operating revenues and income from operations by approximately $7.6 million for the Sequestration Reduction and $2.1 million for the MPPR Reduction, respectively.  Excluding the impact of these reductions, net operating revenues would have increased 3.0% for the quarter ended March 31, 2014, compared to the same quarter, prior year.  Income from operations was $78.4 million for the quarter ended March 31, 2014, compared to $82.5 million for the same quarter, prior year.  Net income attributable to Select Medical was $33.0 million for the quarter ended March 31, 2014, compared to $34.4 million for the same quarter, prior year.  Net income attributable to Select Medical for the quarter ended March 31, 2014 and 2013 includes losses on early retirement of debt, net of tax, of $1.4 million and $0.9 million, respectively. Net income before interest, income taxes, depreciation and amortization, gain (loss) on early retirement of debt, stock compensation expense, equity in earnings (losses) of unconsolidated subsidiaries and other income (expense) (“Adjusted EBITDA”) for the quarter ended March 31, 2014 was $96.8 million, compared to $100.1 million for the same quarter, prior year.  A reconciliation of net income to Adjusted EBITDA is presented in table V of this release.  Excluding the effect of the Sequestration Reduction and MPPR Reduction, Adjusted EBITDA would have increased 6.5%, compared to the same quarter, prior year.  Income per common share for the both the quarters ended March 31, 2014 and 2013 was $0.24 on a fully diluted basis.  Excluding the loss related to the early retirement of debt in each period and their related tax affects, adjusted income per common share was $0.25 per diluted share for both the quarters ended March 31, 2014 and 2013.  A reconciliation of net income per share to adjusted net income per share for both the quarters ended March 31, 2014 and 2013 is presented in table VI of this release.

Specialty Hospitals

For the quarter ended March 31, 2014, net operating revenues for the specialty hospital segment increased 1.2% to $564.6 million, compared to $557.8 million for the same quarter, prior year.  The Sequestration Reduction reduced both net operating revenues and income from operations for the segment by approximately $7.2 million for the quarter ended March 31, 2014.  Excluding the impact of this reduction, net operating revenues would have increased 2.5% for the first quarter ended March 31, 2014, compared to the same quarter, prior year.  Adjusted EBITDA for the specialty hospital segment was $92.2 million for the quarter ended March 31, 2014, compared to $93.3 million for the same quarter, prior year.  Excluding the effect of the Sequestration Reduction, Adjusted EBITDA would have increased 6.5%, compared to the same quarter, prior year.  The Adjusted EBITDA margin for the segment was 16.3% for the quarter ended March 31, 2014, compared to 16.7% for the same quarter, prior year.  Certain specialty hospital key statistics for both the quarters ended March 31, 2014 and 2013 are presented in table IV of this release.

Outpatient Rehabilitation

For the quarter ended March 31, 2014, net operating revenues for the outpatient rehabilitation segment increased 3.0% to $197.9 million, compared to $192.1 million for the same quarter, prior year.  The Sequestration Reduction and MPPR Reduction reduced both net operating revenues and income from operations for the segment by approximately $0.4 million for the Sequestration Reduction and $2.1 million for the MPPR Reduction for the quarter ended March 31, 2014.  Excluding the impact of these reductions, net operating revenues would have increased 4.3% for the quarter ended March 31, 2014, compared to the same quarter, prior year.  In addition, our outpatient rehabilitation segment was adversely affected by the severe winter weather in several of our markets.  Adjusted EBITDA for the segment for the quarter ended March 31, 2014 decreased 8.1% to $21.0 million, compared to $22.8 million for the same quarter, prior year.  Excluding the effect of the Sequestration Reduction and MPPR Reduction, Adjusted EBITDA would have increased 3.1%, compared to the same quarter, prior year.  The Adjusted EBITDA margin for the segment was 10.6% for the quarter ended March 31, 2014, compared to 11.9% for the same quarter, prior year.  Certain outpatient rehabilitation key statistics for both the quarters ended March 31, 2014 and 2013 are presented in table IV of this release.

Certain statements contained herein that are not descriptions of historical facts are “forward-looking” statements (as such term is defined in the Private Securities Litigation Reform Act of 1995).  Because such statements include risks and uncertainties, actual results may differ materially from those expressed or implied by such forward-looking statements due to factors including the following:

·                        changes in government reimbursement for our services due to the implementation of healthcare reform legislation, deficit reduction measures, and/or new payment policies (including, for example, the expiration of the moratorium limiting the full application of the 25 Percent Rule that would reduce our Medicare payments for those patients admitted to a long term acute care hospital from a referring hospital in excess of an applicable percentage admissions threshold) may result in a reduction in net operating revenues, an increase in costs and a reduction in profitability;

·                        the impact of the Bipartisan Budget Act of 2013, which establishes new payment limits for Medicare patients who do not meet specified criteria, may result in a reduction in net operating revenues and profitability of our long term acute care hospitals;

·                     the failure of our specialty hospitals to maintain their Medicare certifications may cause our net operating revenues and profitability to decline;

·                     the failure of our facilities operated as “hospitals within hospitals” to qualify as hospitals separate from their host hospitals may cause our net operating revenues and profitability to decline;

·                     a government investigation or assertion that we have violated applicable regulations may result in sanctions or reputational harm and increased costs;

·                     acquisitions or joint ventures may prove difficult or unsuccessful, use significant resources or expose us to unforeseen liabilities;

·                     private third-party payors for our services may undertake future cost containment initiatives that limit our future net operating revenues and profitability;

·                     the failure to maintain established relationships with the physicians in the areas we serve could reduce our net operating revenues and profitability;

·                     shortages in qualified nurses or therapists could increase our operating costs significantly;

·                     competition may limit our ability to grow and result in a decrease in our net operating revenues and profitability;

·                     the loss of key members of our management team could significantly disrupt our operations;

·                     the effect of claims asserted against us could subject us to substantial uninsured liabilities; and

·                     other factors discussed from time to time in our filings with the Securities and Exchange Commission, including factors discussed under the heading “Risk Factors” of the annual report on Form 10-K.

V.  Net Income to Adjusted EBITDA Reconciliation

For the Three Months Ended March 31, 2013 and 2014

(In thousands, unaudited)

The following table reconciles net income to Adjusted EBITDA for Select Medical.  Adjusted EBITDA is used by Select Medical to report its segment performance.  Adjusted EBITDA is defined as net income before interest, income taxes, depreciation and amortization, gain (loss) on early retirement of debt, stock compensation expense, equity in earnings (losses) of unconsolidated subsidiaries and other income (expense).  The Company believes that the presentation of Adjusted EBITDA is important to investors because Adjusted EBITDA is commonly used as an analytical indicator of performance by investors within the healthcare industry.  Adjusted EBITDA is used by management to evaluate financial performance and determine resource allocation for each of its operating units.

Adjusted EBITDA is not a measure of financial performance under generally accepted accounting principles.  Items excluded from Adjusted EBITDA are significant components in understanding and assessing financial performance.  Adjusted EBITDA should not be considered in isolation or as an alternative to, or substitute for, net income, cash flows generated by operations, investing or financing activities, or other financial statement data presented in the consolidated financial statements as indicators of financial performance or liquidity.  Because Adjusted EBITDA is not a measurement determined in accordance with generally accepted accounting principles and is thus susceptible to varying calculations, Adjusted EBITDA as presented may not be comparable to other similarly titled measures of other companies.

(a)         Other primarily includes general and administrative costs.
