Sterigenics International has Acquired Nelson Laboratories

Acquisition creates largest fully integrated global sterilization and lab services operation.

Sterigenics International LLC, the leading global provider of contract sterilization, gamma technologies and medical isotopes, and a portfolio company of Warburg Pincus and GTCR, today announced that it has acquired Nelson Laboratories, Inc., the largest U.S. provider of life-cycle microbiology testing services for the medical devices, pharmaceutical and tissue industries. Terms of the transaction were not disclosed.

Nelson Labs employs 570 professionals, including more than 300 scientists and 60 registered and specialist microbiologists. With 85 labs running out of five corporate buildings in Salt Lake City, they work with more than 3,000 client companies in 57 countries, providing more than 400 microbiological and analytical tests.

All Nelson Labs operations will remain in Salt Lake City and be combined with Sterigenics' existing microbiological and analytical testing and consultancy - SteriPro® Labs. Moving forward, the combined entities will go to market under the Nelson Labs brand name and operate as a standalone business unit within Sterigenics International. Jeffery Nelson will serve as President of Nelson Labs and together, with the Sterigenics contract sterilization business, will create the largest fully integrated global sterilization and lab services firm in the world.

"This is a significant strategic acquisition to help build out Sterigenics' lab testing and service capabilities on a global scale, enabling us to better serve our multinational customers," said Michael Mulhern, CEO of Sterigenics International. "We will continue to explore additional expansion opportunities for our lab services to meet our customers' growing needs."

"We are incredibly impressed with Nelson Labs' leadership, culture, customer oriented service and commitment to quality," continued Mulhern. "We believe that the fit is perfect with Sterigenics and look forward to working together on our shared mission of improving global public health."

"Sterigenics will be a great partner, and will provide the global access and ongoing investment necessary to ensure long-term growth of the lab services business," said Jeffery Nelson. "They are a global leader in contract sterilization and sterility assurance serving the same markets as Nelson Labs. This is an excellent cultural fit, and I'm excited for the opportunities this will bring for our teams and our customers throughout the world."
