Clayton, Dubilier & Rice has reached an agreement to sell PharMEDium, a provider of outsourced compounded sterile preparations to acute care hospitals in the U.S., to AmerisourceBergen (NYSE: ABC) for $2.575 billion in cash. Founded in 2003, PharMEDium maintains four compounding facilities, provides a range of 2,000 SKUs and serves over 3,000 customers across all 50 U.S. states. CD&R acquired the company early last year for roughly $950 million. PharMEDium had filed for an IPO over a month ago, intending to list on the NYSE under the symbol PMHC. The sale to AmerisourceBergen is expected to close by year end.
