ThunderCat pushes back on $500M VA award to Peraton Through its acquisition of Perspecta, Peraton quickly pulled in an estimated $500 million contract to help the Veterans Affairs Department carry out a cloud migration effort. But before Peraton could celebrate, that win was challenged by another competitor who disagreed with VA’s choice. ThunderCat Technology has filed a protest with the Government Accountability Office to argue the evaluation was not conducted properly. If it had, the VA would have picked ThunderCat instead. Perspecta's proposal was selected for the award on May 25, nearly two weeks after it was folded into Peraton. ThunderCat then filed its protest June 1 with the GAO decision due Sept. 9.
