Robbins LLP, a shareholder rights litigation firm, is encouraging Pinterest, Inc. (NYSE: PINS) stockholders who lost money investing in the company to contact the firm about potentially leading a class action lawsuit. The lawsuit alleges that Pinterest misled investors about its revenues from advertising partners, particularly the impact of U.S. tariffs on its business.

Why it matters

This case could have significant financial implications for Pinterest and its shareholders, as the lawsuit alleges the company failed to properly disclose the negative impact of macroeconomic factors on its advertising revenue. The outcome could set an important precedent for how social media platforms communicate with investors about external forces affecting their business.

The details

According to the complaint, during the class period from February 7, 2025 to February 12, 2026, Pinterest failed to disclose that it was experiencing or likely to experience reduced revenues from its advertising partners, and that it overstated its ability to manage the impact of U.S. tariffs on its operations. The lawsuit alleges these factors were significant enough that Pinterest was facing an imminent restructuring. On February 12, 2026, Pinterest announced quarterly revenue below analyst estimates and provided Q1 2026 guidance also below consensus, citing the impact of tariffs on its top retail advertisers. This news caused Pinterest's stock price to fall over 16%.

  • The class period is from February 7, 2025 to February 12, 2026.
  • Shareholders must file to serve as lead plaintiff by May 29, 2026.
