Overview

• MPRM filed a multi-claim lawsuit in California state court on Sept. 19 alleging 42West poached roughly half its staff, clients and confidential materials.
• The departures included executive vice presidents Sylvia Desrochers and Caitlin McGee, who had explored buying the firm before those talks fell apart.
• MPRM says Desrochers emailed on Sept. 17 that Disney, NBC, National Geographic and others would move their business to 42West.
• The complaint cites alleged misappropriation of trade secrets, including marketing plans, client lists and customer profiles, and seeks damages plus an injunction to bar their use.
• MPRM says six major clients have terminated contracts and that its sale process has paused, while 42West has not been served and has not provided substantive comment.
