EXPLANATORY NOTE

ITEM 5.07 SUBMISSION OF A MATTER TO A VOTE OF SECURITY HOLDERS. 

On January 9, 2026, Ribbon Acquisition Corp. (the “Company”) held a Special Meeting of Stockholders (the “Special Meeting”). The record date for stockholders entitled to notice of, and to vote at, the Special Meeting was December 9, 2025. As of the close of business on the record date, there were 6,470,000 ordinary shares issued and outstanding and entitled to vote at the Special Meeting. Of these shares, 4,976,677 shares (representing 76.92% of the outstanding ordinary shares), constituting a quorum, were present in person or represented by proxy at the Special Meeting.

At the Special Meeting, five proposals were submitted to the Company’s stockholders, each as described in more detail in the Company’s definitive proxy statement. The final voting results were as follows:

Proposal 1

The Company’s stockholders approved an amendment (the “Extension Amendment”) to the Company’s Amended and Restated Memorandum and Articles of Association to extend the date by which the Company must consummate an initial business combination from January 16, 2026 to January 16, 2027, or such earlier date as may be determined by the Company’s Board of Directors.

Proposal 2

The Company’s stockholders approved an amendment to the Company’s Investment Management Trust Agreement, dated January 14, 2025, to extend the date by which the Company must complete an initial business combination from January 16, 2026 to January 16, 2027, and to provide for a monthly extension payment of $125,000 to be deposited into the trust account for each monthly extension period.

Proposal 3

The Company’s stockholders approved an amendment to the Investment Management Trust Agreement to remove the provision permitting the Company to withdraw up to US$100,000 of interest earned on the trust account to pay dissolution expenses.

Proposal 4

The Company’s stockholders approved a proposal requiring the Company to file a Current Report on Form 8-K for each monthly extension payment made in connection with the Extension Amendment and the Trust Amendment.

Proposal 5

The Company’s stockholders approved a proposal to direct the chairwoman of the Special Meeting to adjourn the Special Meeting to a later date or dates, if necessary, to permit further solicitation and voting of proxies if there were insufficient votes to approve Proposal 1 or Proposal 2.

The Company’s stockholders approved the Extension Amendment at the Special Meeting. In connection with such approval, the Company intends to file an amendment to its Amended and Restated Memorandum and Articles of Association with the Registrar of Companies of the Cayman Islands to reflect the approved amendments promptly following the Special Meeting.

In connection with the Special Meeting, holders of 1,436,867 public Class A ordinary shares exercised their right to redeem such shares for a pro rata portion of the funds in the Company’s trust account, for an aggregate redemption amount of $14,937,325.92, representing a per-share redemption price of approximately $10.395761.
