Rosen Law Firm announced a class action lawsuit involving Dun & Bradstreet Holdings, Inc. (NYSE: DNB) and investors affected by its August 26, 2025 merger with affiliates of Clearlake Capital Group, L.P. The proposed class includes people or entities that sold D&B common stock on the open market from May 13, 2025, through August 26, 2025; exchanged shares for $9.15 per share in cash in the merger; or held shares on the May 9, 2025, record date for the special stockholder meeting whose shares were voted on, or entitled to vote on, the deal. A lawsuit has already been filed, and investors seeking to serve as lead plaintiff must move the Court by November 10, 2026. The complaint alleges that D&B's March 23, 2025, merger announcement and May 13, 2025, definitive proxy statement contained false or misleading statements and omitted material information about the company's value, alternatives to a whole-company sale, Executive Chairman Foley's interest in a quick sale, financial projections and ties between Foley and D&B's financial and legal advisers. No class has been certified. Investors may seek information from Rosen Law Firm through its website, by telephone or by email, and may retain counsel, remain absent class members or take no action at this stage.
