Marsh McLennan remains in the No. 1 position with $17.2 billion in total revenues, $6.13 billion ahead of second-place Aon plc. The Aon and Willis Towers Watson marquee deal has not been finalized, so it did not affect Best's Review's annual ranking of global insurance brokers, based on 2020 results.

“While Aon and WTW are working toward completing the proposed combination as soon as possible in the third quarter of 2021, the completion remains subject to the receipt of required regulatory approvals and clearances, including with respect to United States antitrust laws, as well as other customary closing conditions,” Aon said.

That expected combination, along with the newly announced merger of No. 11 Alliant and No. 19 Confie, will likely affect the broker rankings next year. The agreement brings more than 3,500 employees and in excess of 1 million customers under the Alliant banner. Confie returned to the ranking in 2020 for the first time in four years.

The Top 10 remained the same as last year.

M&A Still Going Strong

The pandemic didn't slow down the M&A activity in the agent/broker sector, according to Optis Partner's Agent & Broker 2020 Year-End Merger & Acquisition Report. There were 774 total deals in 2020, nearly 20% more than in 2019. Optis reports Acrisure was the most active acquirer, with 108 deals.

Other M&As of note include Brown & Brown's 25 deals, including its first acquisition in Canada. The No. 6 ranked broker also acquired Irish broker O'Leary Insurances and insurtech CoverHound. NFP, No. 13, closed 27 acquisitions including Rose & Kiernan in the U.K., one of the largest buys in the company's history. AssuredPartners, ranked 12, reports it completed 47 M&As that expanded its footprint in three states.

'A New Old Name'

In November, No. 15 Howden Group Holdings changed its name from Hyperion Insurance Group. Founded in 1994 as Howden Pangborn, the Hyperion name came in to existence in 1998. David Howden, CEO, Howden Group Holdings, said: “It is the right time for us to bring further simplicity and authenticity to the Group and to take on a new old name. I have always been clear that we are building a sustainable business with a difference, and as we grow, we must ensure that we both stay true to our roots and the culture that got us to where we are today, whilst facing forward with the right proposition for our employees and our clients.”
