Diplomat expands hepatitis C specialty services with acquisition of Burman’s Specialty Pharmacy

FLINT, Mich.—Diplomat Pharmacy, Inc. (NYSE: DPLO) announced today it has acquired Burman’s Specialty Pharmacy (Burman’s). Burman’s, located in the greater Philadelphia, Pennsylvania area, is a provider of individualized patient care with a primary focus on the challenging condition of hepatitis C.

“Burman’s shares our strong commitment to patient care,” said Phil Hagerman, Diplomat CEO and Chairman. “We acquired Burman’s to enhance our targeted clinical management programs, utilize its innovative hepatitis C technology platform and strong payor network, and increase our presence in the U.S. mid-Atlantic region.”

Steve Burman, President and CEO of Burman’s, is pleased to partner with Diplomat to continue its history of improving patient results by continually monitoring treatment and ensuring patient compliance. Burman’s enhances therapy management through its proprietary software platform HealthTrac, specifically designed to navigate the complexities of hepatitis C therapy and allow pharmacists and providers to collaborate on patient care.

“According to the Center for Disease Control and Prevention, an estimated 3.2 million people in the United States are living with chronic hepatitis C infection,” said Hagerman. “We believe the HealthTrac technology will significantly expand our hepatitis C services across our national footprint.”

“Diplomat’s patient-centric focus echoes our own approach,” said Burman. “We pride ourselves on improving patient care with innovative technology. HealthTrac opens the lines of communication between all healthcare professionals involved to improve

treatment efficiency in an effort to both improve results and reduce costs. Diplomat shares that vision and puts it into practice with high-touch patient care.”

Burman’s executive leadership will remain in place as their services expand under Diplomat’s ownership. In addition, all individuals and entities receiving Diplomat common stock as part of this transaction will be subject to certain lock-up restrictions on such shares, for at least six months after closing.

Under the terms of the agreement, Diplomat is acquiring Burman’s for $72.8 million cash and $10 million in Diplomat common stock. For the 12 months ended May 31, 2015, Burman’s generated approximately $383 million in revenue and approximately $21 million in EBITDA. The transaction is expected to be accretive to Diplomat’s earnings per share in 2015.  Diplomat funded the cash component of the purchase price with cash on hand along with use of its existing credit facility.
