Private equity firm Warburg Pincus acquired a majority stake in contact sterilization provider Sterigenics International, according to GTCR, which bought the company in 2011.
The deal values the company at more than $2 billion, including debt, said GTCR. Other terms of the transaction were not disclosed.
GTCR will own the remaining stakes in the company, while Warburg Pincus takes control of the majority, GTCR said.
"We are thrilled to close the recapitalization of Sterigenics, and we look forward to working with Warburg Pincus and the Sterigenics team to continue to grow this market leading business," GTCR managing director Dean Mihas said in prepared remarks.
In October 2014, GTCR put Sterigenics up for sale at a $1.5 billion valuation, just 2 months after Sterigenics acquired radioactive isotope supplier and sterilization tech firm Nordion (NYSE:NDZ).
"This is another excellent example of GTCR successfully executing its ‘leaders strategy’ with an exceptional management team. We’re excited to partner again with Michael Mulhern, Phil Macnabb, and the entire Sterigenics team to expand the business through both investments in organic growth and additional acquisitions," GTCR managing director Sean Cunningham said in a press release.
