After a fairly quiet 2014, M&A in the pharmacy benefit management (PBM) segment saw two big deals go down in February. First, Rite Aid Corp. (NYSE: RAD) paid $2 billion for EnvisionRx, a portfolio company of TPG.

Last week, Catamaran Corp. (NASDAQ: CTRX) added to its own portfolio with an all-cash, $405 million deal for Healthcare Solutions, Inc., a portfolio company of Brazos Private Equity Partners LLC.

Healthcare Solutions specializes in pharmacy benefits and other services in the workers’ compensation market, making for a strong addition to Catamaran’s previous acquisitions: Restat, LLC, which provides PBM services for self-funded employers, third-party administrators, workers’ comp plans, health plans and unions; and Salveo Specialty Pharmacy, which focuses on several core therapeutic categories: oncology, hepatitis C, HIV/AIDS, organ transplant, rheumatoid arthritis and gastrointestinal diseases.
