Huntsworth, a Clayton, Dubilier & Rice portfolio company, has announced an agreement to acquire Nucleus Global from its founder, Stephen Cameron.

The combination will create a global leader in the fast growing medical communications space and further establish Huntsworth as a leading Pharma Commercialization platform, offering a suite of medical affairs, market access, and marketing services to large and mid-size pharmaceutical and biotech companies across the life cycle of drugs.

With a 30-year history of organic growth, Nucleus has become one of the largest privately owned medical communications groups with 14 offices around the world and more than 800 experts serving the biggest healthcare and medical assets in the world. Nucleus Founder and Chair, Stephen Cameron will join the main Board of Huntsworth and continue to lead Nucleus.

“This is a transformational milestone for two highly complementary businesses,” said Eric Rouzier, CD&R Partner. “We believe the combined businesses will offer a highly differentiated and complementary suite of high science solutions to support its clients in the pharmaceutical industry in developing and commercializing drugs globally. We are delighted that Stephen will remain with the business through the next phase of its growth.”

CD&R, which acquired Huntsworth in May, has a long track record investing in healthcare businesses globally. Huntsworth Chairman Liam FitzGerald, Operating Advisor to CD&R funds and former CEO of UDG Healthcare, will continue in the Chairman role for the new combined business upon close of the transaction, expected in December 2020.
