Three findings

  1. Credit union purchases of banks have doubled in five years.

    Credit unions announced 63 bank acquisitions from 2020 through 2024, against 32 in the previous five years, and the assets acquired tripled to $22.3 billion. In 2024 credit unions were the buyer in 17% of all US bank acquisitions. Source: CEO Advisory Group analysis of S&P Global Market Intelligence data.

  2. The right bank is usually a quarter of your size or less.

    A credit union pays cash for a bank's equity, so none of the bank's capital comes across and goodwill does not count toward risk-based capital. Advisers interviewed for the paper put the typical target at about 25% of the buyer's assets, with pro forma net worth kept above 8%.

  3. Bank deals turn on price and people, not board seats and names.

    Credit unions typically pay close to two times book value for a bank, against a median of about 1.5 times in bank-to-bank deals, and pay entirely in cash. The questions that stall credit union mergers, such as board seats, the name and the headquarters, rarely arise. Source: Wilary Winn and CEO Advisory Group interviews.

Credit unions are now the buyer in nearly one in five US bank acquisitions, and boards that once dismissed the idea are asking whether a bank belongs in their own growth plan. The harder questions are whether your credit union is the kind that should buy one, which bank would fit, and how buyers find a willing seller before anyone else does. Part 1 draws on five credit unions that have bought banks, three bankers who sold to them, and the attorneys and accountants who structure these deals.
