SageView Advisory Group acquired registered investment adviser firm MJM401k, SageView announced in a news release Thursday.
Terms of the deal, which closed Wednesday, were not disclosed.
The acquisition will add more than 100 retirement plans with $17 billion in assets under advisement to SageView's client roster, SageView said in the news release.
MJM401k provides retirement plan consulting services to institutional clients in a variety of industries.
The transaction follows SageView's acquisition of the retirement plan services practice of RIA firm Arnerich Massena in March. That acquisition boosted SageView's assets by $5.3 billion.
