Alert: Regencell's $14 Billion Market Valuation Built on Zero Revenue Collapsed 18.56% After DOJ Subpoena Revealed Alleged Market Manipulation Investigation

NEW YORK, June 11, 2026 /PRNewswire/ -- SueWallSt notifies investors in Regencell Bioscience Holdings Limited (NASDAQ: RGC) that a class action lawsuit has been filed on behalf of shareholders who purchased securities between October 28, 2024 and October 31, 2025. Find out if you qualify to recover losses. You may also contact Joseph E. Levi, Esq. at [email protected] or (888) SueWallSt.

RGC shares fell $3.09 per share, or 18.56%, closing at $13.56 on November 3, 2025, after the Company disclosed a U.S. Department of Justice subpoena investigating trading in its ordinary shares. The lead plaintiff deadline is June 23, 2026.

A $14 Billion Valuation Untethered From Economic Reality

Regencell achieved a market capitalization of approximately $14 billion despite operating with twelve employees, generating zero revenue, and spending roughly $1 million annually on research and development. The Wall Street Journal noted in January 2026 that only 20 of the 261 companies in the Nasdaq Biotechnology Index carried a greater market value. The lawsuit contends that this extraordinary valuation disconnect was fueled by trading activity unrelated to business fundamentals, and that Defendants knew or recklessly disregarded the manipulation vulnerability that inflated share prices.

The 48,650% Surge and Subsequent Unraveling

The complaint chronicles an extraordinary price trajectory:

• From the start of the Class Period through mid-March 2025, RGC shares traded below $0.30 per share
• By May 1, 2025, shares suddenly closed at $2.03, with no corresponding Company news
• On June 17, 2025, shares reached a Class Period high of $78.00, representing a 48,650% increase from the Class Period start
• Within one week of the peak, shares collapsed to slightly above $20.00
• On November 3, 2025, following the DOJ subpoena disclosure, shares fell an additional 18.56% to $13.56

The filing states that throughout these swings, Defendants attributed volatility to short-selling activity and third-party social media commentary rather than disclosing the Company's vulnerability to market manipulation or the regulatory scrutiny that vulnerability invited.

What the Corrective Disclosure Revealed About Market Risk

On October 31, 2025, Regencell disclosed in its annual report that it had received correspondence and a subpoena from the DOJ "indicating that the DOJ is conducting an investigation into the trading in our Ordinary Shares." The Company acknowledged the DOJ requested documents concerning "corporate operational, financial and accounting matters" and warned it "may be required to pay fines, penalties, damages or settlement costs in excess of our insurance coverage."

The action asserts that this disclosure contradicted months of filings that framed volatility risks in generic, hypothetical terms while concealing that manipulation-driven trading had already attracted federal law enforcement attention.

"When companies fail to disclose material information, shareholders may suffer significant losses. The disparity between Regencell's market valuation and its underlying business fundamentals raises important questions about the adequacy of its risk disclosures during a period of extraordinary trading activity." -- Joseph E.
