EMPLOYEES COMMITTED TO OUR COMMUNITIES FROM OUR NEWEST CONCENTRA EMPLOYEES TO OUR LONG-TIME COLLEAGUES, Select Medical is proud to enhance the lives of those who live in the communities we serve. Across the country, our colleagues dedicate their time and talent to a diverse array of charitable causes. At 73, Edward Bronson was an avid roller-blader. He knew he needed knee surgery but postponed it because he did not want to give up his favorite activity. When he did complete his total knee replacement, his recovery was a challenge. He entered the Select Physical Therapy Clinic in North Miami, Fla., in a wheelchair. Over time, and with the encouragement of his therapists, he made a strong recovery. “What impressed me was the attitude of the therapists; they seemed to really enjoy the work and always met me with a smile … Thanks to you, it will only be a matter of time before I’m back on my blades and entertaining the tourists on South Beach again!” 8200 2 0 1 5 A N N U A L R E P O R T 1 EMPLO IN43 STATE outpatient rehabilitation

A L E T T E R F R O M L E A D E R S H I P At Select Medical, our distinct service lines create a powerful continuum of healing and care. The rich personal experience and professional skill of each of our more than 40,000 employees enhances the support they provide patients at every level of acuity these service lines treat. As a result, our medical and therapeutic expertise is positioning us to be the partner of choice at some of our nation’s most prestigious medical institutions. 2015 marked a new chapter in Select Medical’s history as we completed the acquisition of Concentra through a joint venture. Concentra represents another step toward further solidifying our market presence, while also diversifying our customer profile. With more than 85 percent of its business concentrated in occupational medicine, Concentra’s strengths augment our own while expanding our reach and capabilities. Our specialty hospitals operating as long-term acute care hospitals (LTCHs) began implementing new federal patient criteria. We believe that patient criteria better defines and clearly articulates the role LTCHs play in our nation’s healthcare continuum. Select Medical’s LTCHs are well-positioned to provide care to high-acuity patients defined by the new regulations. However, as we begin to transition our hospitals to the new criteria, it is clear to us that there will be some variability in this sector for the next 18 months. As a company, we strive to respond thoughtfully to regulatory changes and the opportunities that prevail in the marketplace. The specialty hospital division also leveraged our successful partnership model to expand its inpatient rehabilitation hospital operations. We are excited by our progress in partnering with prestigious institutions and strong market brands. As expected, our Cleveland Clinic Rehabilitation Hospital, jointly owned with the Cleveland Clinic, accepted its first patient in December. In 2016, new doors will open in important markets, including a partnership with Cedars-Sinai and UCLA Health System in Los Angeles, the Ochsner Health System in Louisiana and TriHealth in Ohio. Our outpatient division continues to be a strong performer, with meaningful growth in patient visits. We will continue to execute tack-on acquisitions and open new clinics to fill in our markets as opportunities present themselves. As more states embrace the direct access model of physical therapy, our clinics have new opportunities to reach consumers. In more than 40 states, a doctor’s referral is no longer needed to set up a physical therapy appointment. This change gives us the chance to diversify the relationships we have with our referring physicians as we assist them in triaging patients, ensuring that they spend their valuable time on those with the most need. In January 2016, we announced plans to acquire Physiotherapy Associates. The $400 million deal will bring a nationwide provider of outpatient orthopedic, spinal care, and neurological rehabilitation, orthotics and prosthetic services into our outpatient service line. The deal is expected to close in the first or second quarter of 2016. No matter what business conditions present themselves, we remain focused on our four key results: To keep our patients and each other safe; to deliver an exceptional patient experience; to deliver an exceptional employee experience and meet our annual business plan. For us, growth is a long-term objective. It is always exciting when it happens quickly; but as we prepare to celebrate the 20th anniversary of our company’s founding, we look back with appreciation at our vision for building specialized healthcare businesses and the ambitious road we have traveled. Time after time, our 2 S E L E C T M E D I C A L I M P R O V I N G Q U A L I T Y O F L I F E

 resourcefulness and results-oriented leadership drives us forward.
