On August 13, 2025, BUUU Group Limited, a British Virgin Islands company (the “Company”), entered into an underwriting agreement with Dominari Securities LLC (the “Representative”), the representative of the underwriters named therein (the “Underwriters”), pursuant to which the Company agreed to sell to the Underwriters in a firm commitment underwritten initial public offering (the “IPO”) an aggregate of 1,500,000 Class A ordinary shares, of no par value (the “Class A Ordinary Shares”), at an offering price of $4.00 per share. The Company has also granted the Underwriters a 45-day option (the “Over-Allotment Option”), exercisable by the Representative, to purchase up to an additional 225,000 Class A Ordinary Shares to cover over-allotments, if any.

On August 27, 2025, the Representative partially exercised its Over-Allotment Option to purchase an additional 175,000 Class A Ordinary Shares of the Company at the public offering price of US$4.00 per share. The closing for the sale of the Over-Allotment Option took place on September 3, 2025. As a result, the gross proceeds of the Company’s initial public offering, including the proceeds from the exercise of the Over-Allotment Option, totaled approximately US$6.7 million, before deducting underwriting discounts and other related expenses.

A copy of the press release announcing the Representative’s exercise of the Over-Allotment Option is attached as Exhibit 99.1 and incorporated herein by reference.
