Aon and Willis Towers Watson have mutually agreed to end their proposed combination and end litigation with the U.S. Department of Justice (DOJ).
This news comes less than a week after the European Commission had signaled it would approve the merger, although further divestments were required.
"Despite regulatory momentum around the world, including the recent approval of our combination by the European Commission, we reached an impasse with the U.S. Department of Justice," Aon CEO Greg Case said in a comment in the breakup announcement.
"The DOJ position overlooks that our complementary businesses operate across broad, competitive areas of the economy. We are confident that the combination would have accelerated our shared ability to innovate on behalf of clients, but the inability to secure an expedited resolution of the litigation brought us to this point," he said.
Noting the Justice Department filed its antitrust suit as a measure to protect American consumers and businesses, Attorney General Merrick B. Garland said in a a statement: "American companies and consumers rely on competition between Aon and Willis Towers Watson to lower prices for crucial services, such as health and retirement benefits consulting. Allowing Aon and Willis Towers Watson to merge would reduce that vital competition and leave American customers with fewer choices, higher prices and lower quality services."
