What Happened

Investors are being notified that they have until September 21, 2026, to join a securities class action for losses incurred between August 5, 2025, and June 22, 2026. These alerts from law firms including Bernstein Liebhard LLP, Kaplan Fox Kilsheimer LLP, and The Law Offices of Frank R. Cruz have drawn attention to the stock. The news coincided with analyst activity, including a new coverage initiation from Piper Sandler with a Neutral rating and a $90 price target, and UBS maintaining a Buy rating with a lowered price target of $138.
