Emergency Medical Services Corporation Announces New Acquisitions

Greenwood Village, Colo. (January 8, 2013) — Emergency Medical Services Corporation (EMSC or the Company) today announced that its Evolution Health subsidiary has acquired Guardian Healthcare Group, Inc., a post-acute care provider of skilled nursing and therapy services, with operations in Ohio, Oklahoma and Texas. The Company also announced that a clinical affiliate of its EmCare segment has acquired two anesthesiology companies.

Evolution Health is a health care services provider specializing in the post-acute care management of patients with advanced illness and chronic disease. Its physician-led multidisciplinary care teams include nurse practitioners, physician assistants and other clinical providers who provide a full range of services in alternative settings, including the home environment.

“Guardian will complement Evolution Health’s physician-led services in the post-acute care environment by managing patients in a home setting and at other alternative locations. Having an integrated physician-led care team provides a significant enhancement to our service capabilities,” said Steve Boyd, Chief Executive Officer of Guardian Healthcare. Mr. Boyd will serve as CEO of Evolution Health.

According to Bill Sanger, Chief Executive Officer of EMSC, “Currently, most high-acuity patients that transition from hospital-based physician services to home-based services do not receive the type of coordinated health care services provided by Evolution Health’s home based physician-led service model. We are excited about the high level of care that will be provided through the combination of Evolution Health and Guardian, and are confident that this will become a powerful force in the marketplace.”

The Company also announced that an affiliate of EmCare has acquired two anesthesiology companies, Saint Vincent Anesthesia Medical Group, Inc., and Golden State Anesthesia Consultants, Inc. The two companies are affiliated with each other and based in the Los Angeles, California metropolitan area. Both provide outsourced anesthesia services to seven hospitals in southern California, with another scheduled to start in February. They are expected to continue operating under their present brands as part of EmCare.
