Charlesbank Nears $700M MSO Deal for Wood Smith Henning & Berman in Largest US Law Firm Play Yet
Boston private equity firm Charlesbank Capital Partners is in advanced talks to take a stake in insurance defence firm Wood Smith Henning & Berman through a management services organisation, in a transaction that would rank as the largest private equity investment in a US law firm to date.
As reported by Above the Law, the deal values the firm at roughly $700 million, equivalent to about 18 times its adjusted EBITDA of $38.2 million. WSHB posted revenue of $244 million last year and operates more than 500 lawyers across 43 offices in 35 states and London. Charlesbank manages approximately $22 billion and traces its origins to managing Harvard's endowment. The parties have signed a letter of intent, with a definitive agreement expected in the coming weeks.
The structure is the mechanism that makes the investment possible. Rather than acquiring the law firm itself, Charlesbank would take a stake in a separate entity holding WSHB's back office, billing and technology operations, which then supplies those services to the attorney-owned practice for a fee. That split allows outside capital to participate in law firm economics without triggering the prohibition on non-lawyer ownership that applies in most US states.
LawFuel reported the talks on 20 August, framing the transaction as a test of the ownership rules that have kept institutional capital at the perimeter of the US legal market.
The deal follows a wave of MSO formation involving private equity and litigation funders in the personal injury sector, and arrives as several states move to restrict such arrangements.
