D E A RS H A R E H O L D E R We are pleased to report that 2017 was a good year for Select Medical. We successfully executed our long-term acute care criteria strategy; expanded the Company’s national footprint through joint ventures and acquisitions; and remained steadfast in delivering quality care, value and outcomes. These achievements were underscored by strong financial performance in 2017. Net operating revenues grew 3.7% year-over-year to more than $4.4 billion and operating income grew 18.7% year-over-year to $355.9 million. Today, Select Medical is a significant leader of post-acute care in the U.S. We’re the nation’s largest provider of long-term acute care hospital services, outpatient rehabilitation and occupational medicine. Our inpatient We proudly serve the health care needs of 60,000 patients per day who come through our vast network of hospitals, clinics and centers, including: With growth also comes the need to make investments in technology. We continue to implement an electronic medical record (EMR) strategy in both our long-term acute care and inpatient rehabilitation specialty hospitals, as well as deploy other enterprise platforms and digital tools throughout our business lines to increase operational efficiency across the entire organization. Growing in All Business Segments Long-Term Acute Care Hospitals (LTACHs) – We’re pleased to share that after 15 months of operating under the new federally-legislated patient criteria, the great majority of our patients are now meeting these requirements. Our operators have done a very good job educating the health care community on the chronically critically ill patient population for whom Congress expects LTACHs to provide care. another year of expansion propelled by the company’s well-honed joint venture model with an Adjusted EBITDA of $90.0 million, a 58.2% increase. Through our existing partnership with Cleveland Clinic, we opened two new hospitals for a total of 180 beds across the northern Ohio region. New joint venture agreements were also signed with Dignity Health to build and operate a hospital in Henderson, Nevada as well as Ochsner Health with plans to open a hospital in New Orleans in early 2018. In addition, we marked our entry into the Virginia rehabilitation market through a joint venture with Riverside Health. Outpatient Rehabilitation – On the outpatient rehabilitation segment front, even in a challenging year, Adjusted EBITDA was up 2.1% to $132.5 million. Innovation continued to be a priority with a focus on driving ReVital Cancer Rehabilitation Program in clinics across four regional markets including St. Louis, Louisville, Dallas and southern New Jersey. The program is set to expand to an additional six markets throughout 2018. Occupational Medicine – Concentra had another very good year with an Adjusted EBITDA increase of 10.2% from the prior year to $157.6 million. It was also successful in signing a definitive agreement to acquire U.S. HealthWorks (deal closed in early 2018).

 Unifying in Purpose This year, through an initiative called ONE Select, we leveraged the operational and cultural synergies among our lines of business. ONE Select seeks to closely align all facets of the company in order to identify, streamline and implement cohesive operational and cultural best practices across the organization. Our employees sit at the heart of this initiative. In addition to providing exceptional care experiences for our patients and their families, Select Medical was challenged by three natural disasters and rose to the occasion, unifying to help those hit hardest by nature’s wrath. Hurricanes Irma and Harvey and the northern California wildfires were true tests of grit, where our teams showed perseverance, dedication and compassion across many of our hospitals, centers and clinics. Our employees kept patients safe, offered continued or alternate medical care and provided a zone of comfort during and after the disasters. The performance of our teams in these high-stakes, life-threatening situations was nothing less than astounding. These disasters also resulted in the loss of some employees’ homes, vehicles and personal belongings. At this critical juncture, the Select Medical workforce – 42,200 employees strong – immediately stepped in donating funds through the Select Medical Charitable Foundation and providing financial relief to colleagues. We also continued our corporate support for national organizations such as the American Cancer Society, American Heart Association, Special Olympics and Junior Achievement, as well as many regional charities through our C.A.R.E.S. (Caring and Responsive Employees of Select) program. Focusing on Excellence As we embark on 2018, we are confident that our strong leadership, strategic partnerships, clinical excellence and patient-centered innovation will continue to serve as catalysts for growth, improved competitive performance and enhanced shareholder value. We thank you for your support in our ongoing commitment to improve the quality of life for millions of patients and their families in the communities we serve. Sincerely, 2 0 1 7 A N N U A L R E P O R T 3
