Ontario, Calif., April 30, 2012 – Prem Reddy, M.D., FACC, FCCP, Chairman, President and
CEO of Prime Healthcare Services, has been named to Modern Healthcare’s prestigious list of
the “50 Most Influential Physician Executives” for 2012.

Dr. Reddy was picked as the twenty-third most influential physician executive in the nation. This
is the second time he has been recognized on the list, which this year included Regina Benjamin,
Surgeon General of the United States Public Health Service, and Richard Gilfillan, Director of
CMS Center for Medicare & Medicaid Innovation, as well as physician executives from the
Mayo Clinic and Cleveland Clinic.

“I am honored to be selected to this prestigious list,” Dr. Reddy said. “Prime Healthcare, with its
mission of saving hospitals, saving jobs and saving lives, will continue to provide
comprehensive, quality health care in a compassionate, convenient and cost-effective manner.”

Modern Physician and sister publication Modern Healthcare co-sponsor this annual recognition
program. According to Modern Healthcare, the name of the program reflects the skills needed to
improve the healthcare delivery system in the post-healthcare reform era. It takes power to make
reform happen; now it will take influence to make reform work.

Reader nominations are used to create the final ballot for this competition. Readers then vote for
one of 100 physician executives on that ballot. Readers’ votes count for 50 percent of the
outcome. The other 50 percent came from the expert opinions of the senior editors at Modern
Healthcare and Modern Physician.

Prime Healthcare was recognized in 2012 as one of the Top 15 Health Systems in the nation by
Thomson Reuters, based on quality of care, efficiency and patient satisfaction. According to
Thomson Reuters, compared to its peers, Prime Healthcare saved more lives, caused fewer
