World Renowned Law Firm Grant & Eisenhofer Appointed Lead Counsel In Newly Consolidated Class Action Lawsuit Against Canadian Banks CIBC and RBC Alleging Illegal Stock Market Manipulation of Quantum BioPharma Shares
TORONTO, Oct. 08, 2026 (GLOBE NEWSWIRE) -- Quantum BioPharma Ltd. (NASDAQ: QNTM) (FRA: 0K91) (“Quantum BioPharma” or the “Company”), a biopharmaceutical company dedicated to building a portfolio of innovative assets and biotech solutions, today announced that the United States District Court for the Southern District of New York has agreed to consolidate both the Company’s direct action and a class action led by an individual investor alleging market manipulation. In addition, the court appointed experienced law firm Grant & Eisenhofer P.A. (“Grant & Eisenhofer”) as lead counsel in the class action. According to Grant & Eisenhofer, the firm has recovered over USD $30 Billion dollars for its clients to date in some of the most complex, often precedent-setting cases, in fights against the world’s largest and richest opponents.
The Quantum Biopharma lawsuit alleged that between January 1, 2020, and August 15, 2024, the Defendants and/or their customers used “spoofing” techniques to manipulate the share price of Quantum BioPharma shares. The class action lawsuit filed December 11, 2025, alleges that between January 6, 2021, and October 15, 2025, shareholders who sold securities of Quantum Biopharma Ltd., formerly known as FSD Pharma Inc., were significantly and materially harmed.
