Correction of a typographical error in the Press Release issued on September 19, 2025

On September 19, 2025, the Company announced in a press release that it disseminated: “On July 31, 2025, the Company effected a reverse stock split in order to cure the deficiency under Nasdaq Listing Rule 5550(a)(2) for continued listing. On July 31, 2025, the Company’s ordinary shares were also redesignated as Class A ordinary shares (the “ordinary shares”), as previously reported on Form 6-K on August 20, 2025.” The Company would like to clarify that the Company’s Extraordinary General Meeting of Shareholders took place on July 31, 2025 at 10 pm ET at which meeting both these resolutions were passed but that both the reverse stock split and redesignation of ordinary shares (as described further below) took effect on August 25, 2025 at 12:01 am ET. To further elaborate, on the redesignation, the company re-designated the authorized share capital from HK$75,000,000, comprising 750,000,000 Consolidated Shares, into 749,098,320 Class A ordinary shares, par value HK$0.10 each (“Class A Ordinary Shares”), and 901,680 Class B ordinary shares, par value HK$0.10 each (“Class B Ordinary Shares”), with rights, privileges, and restrictions as set out in the amended memorandum and articles of association (the “M&A Amendments”) of the Company, as previously reported on Form 6-K on August 20, 2025.
