Rosen Law Firm Files Class Action Against Dun & Bradstreet

NEW YORK, Sept. 20, 2026 /CourierPR/ -- Rosen Law Firm, a global investor rights law firm, has announced a class action lawsuit on behalf of investors in Dun & Bradstreet Holdings, Inc. (NYSE: DNB). The lawsuit targets individuals who sold shares of DNB common stock in the open market from May 13, 2025, through August 26, 2025, or exchanged shares of DNB common stock into the August 26, 2025, merger with affiliates of Clearlake Capital Group, L.P. for $9.15 per share in cash. Additionally, the lawsuit includes those who held shares of DNB common stock as of the May 9, 2025, Record Date for the special meeting of stockholders and whose shares were voted on, or entitled to vote on, the Merger.

According to the press release, the lawsuit seeks to recover damages on behalf of investors who were allegedly misled by false and misleading statements and omissions in D&B’s March 23, 2025, announcement of the Merger and the May 13, 2025, definitive proxy statement on Schedule 14A. The complaint alleges that the Proxy and other solicitation materials misled investors regarding the true value of D&B and the subject transaction, including portraying the Merger as the product of an ordinary-course strategic review and organic arm’s-length interest in D&B, while omitting Executive Chairman Foley’s personal interest in a quick sale. The complaint also alleges that the Proxy omitted Bank of America Securities’ valuations of superior alternatives to a whole-company sale, misstated that D&B’s Board of Directors had approved downward revisions to D&B’s financial projections, and failed to disclose long-standing, material ties between Foley and D&B’s financial and legal advisors.
