Serco Inc. on Tuesday said it completed its $295 million acquisition of Whitney, Bradley & Brown (WBB) in a deal that allows it to provide full lifecycle support services to its Defense Department customers.

WBB had been a portfolio company of H.I.G. Capital.

Serco Inc., the U.S.-based business of Britain’s Serco Group, said the acquisition strengthens its capabilities in advanced weapons acquisition, program management, wargaming, machine learning, cybersecurity, hypersonics and data analytics.

WBB is expected to add about $230 million in sales to Serco, Inc. this year and brings with it 1,000 employees, more than 75 percent of whom have security clearances. The company is on 35 different government wide acquisition contracts that have a combined ceiling value exceeding $70 billion.

Serco, Inc. has $1.7 billion in annual sales and about 9,000 employees.

“Just as the naval system’s business of Alion joined Serco in 2019 to transform our relationship with the Navy, the expertise of this team makes us a highly credible provider of data-driven technology solutions across the full lifecycle,” Dave Dacquino, chairman and CEO of Serco, Inc., said in a statement.
