The Portnoy Law Firm initiated an investigation into Pinterest, Inc. for potential securities fraud. The firm is evaluating a class action lawsuit to recover losses for affected investors.

The probe follows a 16.83% decline in Pinterest’s stock price on February 13, 2026. This sell-off occurred after the company released its fourth-quarter 2025 financial results. Management expressed dissatisfaction with revenue performance and announced organizational changes to accelerate growth.
