Ascensus, a technology service provider for retirement and other savings vehicles, has agreed to acquire Asperia Retirement Plan Solutions, Ascensus announced.

The move was prompted by Ascensus’ plan to expand its third-party administration division to the Northeast. Ascensus is based in Dresher, Pa.

Asperia, based in Worcester, Mass., and formerly known as Group Health and Benefit Administrators Inc., administers, consults on and develops strategies for defined-contribution and defined-benefit plans.

“We were impressed by their strong business model and solid company culture, and will look to acquire companies that possess similar traits as we continue to execute our growth plans,” said Raghav Nandagopal, the executive vice president of corporate development and mergers and acquisitions for Ascensus.  Terms of the deal were not disclosed.

Ascensus has $163 billion in total assets under administration and services more than 7 million clients through retirement plans, 529 college savings accounts, ABLE accounts, health savings accounts and IRAs.
