WASHINGTON — The Biden administration has sued to block the merger of two of the world’s largest insurance brokers, asserting the deal could eliminate competition, raise prices and hamper innovation for U.S. businesses, employers and unions that use the companies’ services.
The Justice Department on Wednesday announced the antitrust suit filed in federal court in Washington seeking to stop AON’s proposed $30 billion acquisition of rival benefits and risk consultant Willis Towers Watson.
Justice Department officials said the proposed merger would bring together two of the “Big Three” global insurance brokers — the third is Marsh & McLennon — and eliminate competition in five markets.
In seeking separate approval for the merger from European Union authorities, the two companies agreed to divest some of their assets. But Justice Department officials said Wednesday those would not be sufficient to protect U.S. consumers.
The companies provide guidance to many major U.S. companies on administering health and retirement benefits, with the aim of keeping costs down by managing risk.
Both companies are based in London and incorporated in Ireland. AON, with about $11 billion in revenue last year, has some 100 offices in the U.S. Willis Towers Watson, with around $9 billion in 2020 revenue, has 80 U.S. offices.
