The complaint filed by Robbins LLP targets the period between May 11, 2026, and July 23, 2026. During this window, Wise transitioned its primary listing to the Nasdaq Global Select Market. Plaintiffs argue that the company failed to disclose critical regulatory vulnerabilities that surfaced shortly after the move, including a Brussels-based probe into €500 million in suspicious transactions linked to potential fraud and drug trafficking.

Market confidence further soured on July 24, 2026, when the Office of the Comptroller of the Currency denied Wise's application for a national trust bank charter. The regulator cited significant, long-standing compliance deficiencies, causing the company’s stock to drop by 6.2%. Investors who held Wise securities during the class period must submit applications to serve as lead plaintiff by September 28, 2026.
