DEERFIELD, IL, August 17, 2015 – 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 Sao Paulo based Companhia Brasileira de Esterilização (CBE), the largest specialist in sterilization and microbial load reduction in Latin America.

Founded in 1978, CBE was the first company to employ gamma sterilization methods in Brazil, and offers solutions through the largest particle accelerator (E-BEAM) in Latin America.

“This strategic geographic acquisition demonstrates our commitment to expanding our global footprint in order to meet our customers’ growing needs,” said Michael Mulhern, CEO of Sterigenics International. “Going forward, we will continue investing in the future of Sterigenics and building upon our leadership position.”

“We are very excited to add such a high-quality company as CBE to Sterigenics,” said Philip Macnabb, President of Sterigenics International LLC. “CBE brings three facilities into our network with a total processing capacity of 12 million cubic feet. With the addition of CBE we now offer six locations for processing in Latin America, including sites in Costa Rica and Mexico.”

In 2014, a Sterigenics affiliate acquired Nordion, the world’s largest provider of Cobalt-60, an isotope that produces gamma radiation and is a critical component of the gamma sterilization process, creating the only vertically integrated sterilization services company in the world. Additional acquisitions in 2014 included Florida-based gamma irradiation operator FTSI, as well as Gammarad, Italy’s leading gamma irradiation sterilization company, which now serves as the company’s second gamma sterilization facility in Western Europe.
