Mergers and acquisitions activity for RIAs in 2015 was fast, furious, trend setting and record breaking, according to the recently released Nuveen/DeVoe RIA Deal Book.

The number of deals transacted in a year — and in one quarter — hit record highs, for example, as did the number of sellers with over $5 billion in AUM.

This surge in RIA M&A activity "is a natural phase of consolidation that most hyper-fragmented industries experience as they mature,” says David DeVoe, managing partner at DeVoe & Company, a valuation, consulting and investment banking firm specializing in RIAs. “We expect this momentum to continue and potentially accelerate over the next five to seven years.”
