The litigation, docketed as 26-cv-62465, represents investors who purchased Celsius securities between February 21, 2025, and June 3, 2026. Plaintiffs allege that the company falsely maintained its products were safe while actively marketing high-caffeine beverages to minors. According to the complaint, a single 12-ounce Alani Nu drink contains 200 milligrams of caffeine, exceeding the recommended daily limits for adolescents and posing potential cardiovascular risks.

The legal challenge gained momentum following a wrongful death lawsuit filed by the family of a 17-year-old Texas teenager, who alleged that the consumption of Alani Nu products contributed to a fatal cardiac event. Following reports of this incident and a subsequent investigation launched by Texas Attorney General Ken Paxton into the company's marketing practices, Celsius stock experienced significant declines. Investors have until November 3, 2026, to seek appointment as lead plaintiff in the case brought by Pomerantz LLP.
