The market, in three numbers

The buyers have changed. Here’s by how much.

Firms buying firms with partner capital used to lead this market. Now private-equity sponsors do, mostly through the alternative practice structure, which keeps audit work in a CPA-owned firm while outside capital funds the rest.

The data point

A slowdown, with an asterisk

January was the high point of the year through May. The trailing 12-month total crested at 226 in March. Meanwhile, PE capital raised for accounting-focused funds is up 16.1% year over year, to $12.7 billion.

“The deceleration is real in the exact months of April and May, but the trailing window is a floor, not a ceiling.”
