Legal proceedings

The Group is party to a lawsuit initially filed on notice on September 3, 2024, by Karen Cheung (“Plaintiff”) in the Supreme Court of the State of New York, County of New York (“State Court Action”) (Index No. 654541/2024), which sought relief arising from (i) violations of the federal Racketeer Influenced and Corrupt Organizations Act

(“RICO”), 18 § U.S.C. 1961(c), (ii)conspiracy to violate RICO, 18 U.S.C. § 1961(d), (iii) fraud, (iii) breach of fiduciary duty, (iv) negligent misrepresentation, (v) unjust enrichment, (vi) civil conspiracy and (vii) violations of the federal Securities Act of 1933, 15 § U.S.C. 77a et. seq. On December 27, 2024, the Group filed a Notice of Removal in the U.S. District Court for the Southern District of New York (Case No.1:24-cv-09969-VSB-OTW) removing the State Court Action to federal court. On December 30, 2024, the Group filed a demand for service of the complaint on the Group. Plaintiff filed and served her Complaint on the Group on February 24, 2025, alleging claims for (i) violations of RICO 18 U.S.C. § 1962(c), (ii) conspiracy to violate RICO 18 U.S.C. § 1962(d), (iii) fraud; (iv) aiding and abetting breach of fiduciary duty, (v) unjust enrichment, and (vi) civil conspiracy. Following a motion, Plaintiff was granted leave to amend her Complaint and filed a First Amended Complaint on June 2, 2025. The parties entered into a briefing schedule on the Group’s anticipated motion to dismiss (“Motion to Dismiss”), and the Group filed its opening brief on the Motion to Dismiss on July 18, 2025. Plaintiff filed her opposition to the Motion to Dismiss on September 5, 2025, and the Company’s reply in support of the Motion to Dismiss is due on October 6, 2025. The Group continues to believe that Plaintiff’s claims have no merit. As such, the Group will continue to vigorously defend against Plaintiff’s claims. At this time, it is too early to estimate the costs and expenses of defending the lawsuit.

From time to time, the Group may be subject to certain legal proceedings, claims and disputes that arise in the ordinary course of business. Although the outcomes of these legal proceedings cannot be predicted, the Group does not believe these actions, in the aggregate, will have a material adverse impact on its financial position, results of income or liquidity.

Legal proceedings

On December 16, 2024, the Group received a letter from Carey Olsen with a Summons with Notice dated September 3, 2024, taken out by Karen Cheung (a/k/a Wing TSZ Cheung) as plaintiff against, among others, the Group as defendant in the Supreme Court of the State of New York County of New York, in relation to an action to recover financial losses sustained by the plaintiff (the “Case”). The Case is at the very early stages of litigation and although we intend to defend the lawsuit, there can be no assurance regarding the ultimate outcome of this case.

From time to time, the Group may be subject to certain legal proceedings, claims and disputes that arise in the ordinary course of business. Although the outcomes of these legal proceedings cannot be predicted, the Group does not believe these actions, in the aggregate, will have a material adverse impact on its financial position, results of income or liquidity.
