Event Summary

GT Biopharma, a United States — Los Angeles-based biopharmaceutical company, terminated its Chief Medical Officer Richard Graydon on July 17, 2026, citing reasons unrelated to his activities at the company. Shortly thereafter, media reports revealed that Graydon was actually Ronald L. Fischer, a fugitive who had disappeared during his 2005 rape trial and had been on the run for over 20 years. Fischer was arrested in late July 2026 by a federal task force and the United States — United States Coast Guard off the coast of United States — New Jersey. Following the news, Immix's stock price fell significantly, dropping 14.15% on July 20, 2026. Several law firms, including Pomerantz LLP, Block & Leviton, and Portnoy Law Firm, have launched investigations into whether Immix and its leadership violated federal securities laws. The company has stated that given Fischer's short tenure, there was no material effect on the business. The incident has raised questions about the company's hiring practices and has led to investor concern.
