Robbins LLP has filed a class action lawsuit on behalf of Pinterest, Inc. (NYSE: PINS) shareholders who purchased stock between February 7, 2025 and February 12, 2026. The lawsuit alleges that Pinterest failed to disclose that it was experiencing reduced advertising revenues, overstated its ability to manage the impact of U.S. tariffs, and was facing an imminent restructuring.

Why it matters

The class action lawsuit alleges that Pinterest's failure to disclose these material facts misled investors and caused significant stock price declines when the issues were finally revealed. Shareholders who lost money investing in Pinterest during the class period may be eligible to participate in the lawsuit and potentially recover their losses.

The details

According to the complaint, Pinterest announced on February 12, 2026 that its quarterly revenue of $1.32 billion was below analyst estimates, and provided Q1 2026 revenue guidance that also missed expectations. Pinterest's CEO and CFO attributed the performance to an "exogenous shock" related to tariffs that were "disproportionately affecting ad spend from our top retail advertisers". On this news, Pinterest's stock price fell 16.83% to $15.42 per share.

  • The class period is February 7, 2025 to February 12, 2026.
  • The lawsuit was filed on April 15, 2026.
  • The deadline for shareholders to join the class action as the lead plaintiff is May 29, 2026.
