The complaint filed by Robbins LLP focuses on a period between February 21, 2025, and June 3, 2026. Plaintiffs argue that Celsius failed to disclose significant cardiac risks associated with the drinks, which contain 200 milligrams of caffeine—double the daily recommended limit for individuals aged 12 to 17. The legal action follows a wrongful death suit involving a Texas teenager, which triggered an investigation by Texas Attorney General Ken Paxton into potential violations of state trade practice laws.

Market volatility followed these revelations. Celsius shares dropped 4.18% on April 10, 2026, after reports surfaced regarding the wrongful death case. A sharper decline of 7.53% occurred on June 4, 2026, following the announcement of the Attorney General's investigation. Investors who suffered losses during the class period are eligible to participate in the litigation, with a lead plaintiff deadline set for November 3, 2026. Robbins LLP is representing investors on a contingency fee basis.
