The legal action follows a June 1 report from The Wall Street Journal, which indicated that public prosecutors in Brussels are nearing a decision to summon the firm to court over potential money laundering offenses. The news caused an immediate and sharp drop in Wise Group's stock price during intra-day trading on June 1, 2026. Rosen Law is now organizing a prospective class action to recover losses for investors who purchased securities during the period in question.

Investors seeking to join the action are encouraged to contact Phillip Kim at the firm to discuss their eligibility. Rosen Law, which specializes in securities litigation, emphasizes its history of securing large-scale settlements, including a 2019 recovery exceeding $438 million. The firm’s legal team, led by partners Laurence Rosen and Phillip Kim, maintains that shareholders may be entitled to compensation through a contingency fee arrangement, meaning participants do not incur out-of-pocket costs for the litigation process.
