Rosen Law Firm is reminding Dun & Bradstreet Holdings investors about a November 10, 2026 deadline to seek appointment as lead plaintiff in a securities class action. The lawsuit concerns investors who sold D&B common stock from May 13, 2025 through August 26, 2025, exchanged shares in the August 26 merger with affiliates of Clearlake Capital Group, L.P. for $9.15 per share in cash, or held shares on the May 9, 2025 record date and voted, or were entitled to vote, on the transaction. The complaint alleges that D&B’s March 23 merger announcement and May 13 definitive proxy statement contained false or misleading statements and omitted material information about the company’s value, alternatives to the sale and Executive Chairman Foley’s interests and relationships. No class has been certified, and investors may retain their own counsel, remain absent class members or seek lead-plaintiff status.
