On August 7, 2026, Hung-Wen (Howard) Chen ("Mr. Chen") and his wholly-owned investment vehicle, King Regent Management Limited ("King Regent"), entered into subscription agreements (the "Subscription Agreements") with the Issuer. Pursuant to the Subscription Agreements: (i) Mr. Chen agreed to acquire an aggregate of 270,000 Class A Shares, consisting of 103,333 Class A Shares for cash at a purchase price of $15.00 per share and 166,667 Class A Shares issued upon the automatic conversion of Mr. Chen's Convertible Promissory Note, dated March 30, 2026, at a conversion price of $12.00 per share; and (ii) King Regent agreed to purchase 266,667 Class A Shares for cash at a purchase price of $15.00 per share. The private placement transaction closed on August 14, 2026 (the "Private Placement Transaction"). The cash consideration for the subscriptions was funded using the respective personal funds and working capital of Mr. Chen and King Regent.

Mr. Chen and King Regent acquired the Class A Shares in the Private Placement Transaction for investment purposes. The Reporting Persons may from time to time review their investment and, subject to market conditions, acquire or dispose of Class A Shares in open market or private transactions.

As of the date of this Amendment No. 2, Mr. Chen beneficially owns 1,453,029 Class A Shares in the aggregate, representing approximately 49.76% of the outstanding Class A Shares. Such beneficial ownership consists of: (i) 403,334 Class A Shares held directly by Mr. Chen; (ii) 15,000 Class A Shares held in Mr. Chen's brokerage account following the settlement of previously vested RSUs; (iii) 5,000 Class A Shares issuable upon the settlement of RSUs held directly by Mr. Chen that are scheduled to vest within 60 days of the date of this statement (on September 15, 2026); and (iv) 1,029,695 Class A Shares held directly by King Regent. Mr. Chen is the sole director and shareholder of King Regent and therefore shares voting and dispositive power over the shares held by King Regent. The percentage of Class A Shares beneficially owned is based on 2,914,962 Class A Shares outstanding immediately following the closing of the Private Placement Transaction, plus 5,000 Class A Shares issuable upon the vesting of Mr. Chen's RSUs within 60 days, which are deemed outstanding pursuant to Rule 13d-3(d)(1) (yielding an individualized denominator of 2,919,962 shares).

Mr. Chen has sole voting and dispositive power over 423,334 Class A Shares (consisting of the shares described in clauses (i), (ii), and (iii) of Item 5(a) above). Mr. Chen shares voting and dispositive power over 1,029,695 Class A Shares held directly by King Regent.

Mr. Chen and King Regent have not effected any transactions in the Class A Shares during the past 60 days, except for the Private Placement Transaction and note conversion closed on August 14, 2026, as described in Item 3.

Except as described in this Schedule 13D, no other person is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Class A Shares beneficially owned by the Reporting Persons.
