On March 4, 2019, the Company filed a Motion to Dismiss the First Amended Complaint, which was granted in part and dismissed in part on March 30, 2020. The surviving claims against the Company include trademark infringement under 15 U.S.C. § 1114, false advertising under 15 U.S.C. § 1125, and unfair competition under New York common law. On May 29, 2020, the Company filed its Answer to the Amended Complaint.

Chanel then sought a partial stay of discovery on the Company's counterclaims and unclean hands defense while Chanel's motion to dismiss and strike those claims are pending, and on March 10, 2022, the Court granted Chanel's request. Since then, the parties have continued to engage in fact discovery regarding Chanel's counterfeiting and false advertising claims against the Company. Fact discovery was scheduled to be completed by August 15, 2023, however, on July 19, 2023, the Court ordered a stay of the case at the parties’ request to enable the parties to attempt mediation again.

The final outcome of this litigation, including our liability, if any, with respect to Chanel’s claims, is uncertain. An unfavorable outcome in this or similar litigation could adversely affect the Company’s business and could lead to other similar lawsuits. The Company is not able to predict or reasonably estimate the ultimate outcome or possible losses relating to this claim. Beginning on September 10, 2019, purported shareholder class action complaints were filed against the Company, its officers and directors and the underwriters of its IPO in the San Mateo Superior Court, Marin County Superior Court, and the United States District Court for the Northern District of California.

On March 24, 2022, the court entered an order preliminarily approving the settlement. On July 28, 2022, the court entered an order finally approving the settlement and dismissing the case. The financial terms of the stipulation of settlement provide that the Company will pay $11.0 million within thirty (30) days of the later of preliminary approval of the settlement or plaintiff’s counsel providing payment instructions. The Company paid the settlement amount on March 29, 2022 with available resources and recorded approximately $11.0 million for the year ended December 31, 2021 under our Operating expenses as a Legal settlement.
