This is a plaintiff-law-firm press release seeking lead plaintiffs, not a substantive court ruling. The underlying allegations are already priced in from the May 7 earnings collapse. Monitor for (1) lead plaintiff appointment deadline (typically 60 days from filing), (2) any motion to dismiss, and (3) whether the company discloses additional SEC or DOJ investigations. The lawsuit itself is unlikely to move the stock near-term unless discovery reveals new damaging facts.

Executive Summary
Robbins LLP announced a securities class action lawsuit against Planet Fitness (PLNT) alleging the company misled investors about its ability to execute the Black Card price increase, membership growth, and marketing effectiveness. The complaint centers on the May 7, 2026 earnings release that slashed same-store growth guidance from 4-5% to 1%, withdrew the three-year growth algorithm, and paused the Black Card rollout, causing a 31% single-day stock decline. This is a plaintiff-firm press release seeking lead plaintiffs, not a court ruling or settlement.
