Regencell shares fell $3.09 per share, or 18.56%, closing at $13.56 on November 3, 2025, after the Company disclosed a DOJ subpoena investigating trading in its ordinary shares. The lead plaintiff deadline is June 23, 2026.
What They Allegedly Knew
The lawsuit contends that throughout the Class Period, Regencell's leadership was aware that the Company's stock was vulnerable to market manipulation and that the extraordinary volatility bore no relationship to business fundamentals. The Company's own filings acknowledged that price swings were "unrelated or disproportionate to the operating performance of our company." Yet rather than disclose the specific risk that manipulation could trigger governmental enforcement, the action alleges that management buried the issue behind generic warnings about short squeezes and third-party social media commentary.
Defendant Yat-Gai Au owned 88.6% of the Company's shares. As the complaint chronicles, this concentration meant that any significant price movement directly affected his net worth, creating what the filing describes as powerful incentive to remain attuned to trading irregularities.
The Red Flags That Emerged
- Regencell traded below $1.00 per share for years before a sudden 48,650% surge to $78.00 per share by June 17, 2025, with no corresponding business developments
- The Company had twelve employees, zero revenue, zero approved products, and R&D spending of roughly $1 million annually against an acknowledged industry standard of $4 billion to $10 billion per drug
- A 38-for-1 stock split in June 2025 was followed by extreme single-day swings, including an intraday range of $26.20 to $83.60 on June 16, 2025
- Despite these extraordinary patterns, SEC filings attributed volatility only to short sellers and unnamed social media activity
- Post-Class Period, Bloomberg reported three separate double-digit percentage surges in early 2026, each disconnected from any Company news
Inside Knowledge vs. Public Statements
The securities action alleges that the gap between what insiders observed and what shareholders were told was material. Sarbanes-Oxley certifications signed by the Individual Defendants affirmed that SEC filings contained no untrue statements and omitted no material facts. The complaint challenges those certifications, asserting that the filings failed to disclose that market manipulation had subjected Regencell to heightened risk of regulatory scrutiny from the DOJ.
As pleaded in the complaint, the October 31, 2025 annual report finally revealed that the Company had received a DOJ subpoena requesting documents concerning trading activity and "other corporate operational, financial and accounting matters." The filing warned of potential "fines, penalties, damages or settlement costs" and possible "administrative, injunctive, or other proceedings" against the Company and its officers.
"The timeline raises important questions about when certain risks were known internally versus when they were disclosed to the investing public," stated Joseph E. Levi, Esq.
