Appointment of Mr. Wei Shao as Independent Director

On May 13, 2026, the board of directors (the “Board”) of SuperX AI Technology Limited (the “Company”) appointed Mr. Wei Shao (“Mr. Shao”) as an independent director of the Company, and as Chairperson of the Nominating and Corporate Governance Committee of the Company, effective immediately. Based on the information provided by Mr. Shao in connection with the appointment, the Board has determined that Mr. Shao qualifies as an “independent director” within the meaning of Nasdaq Listing Rule 5605(a)(2) and Rule 10A-3 under the Securities Exchange Act of 1934, as amended.

The biographical information of Mr. Shao is set forth below:

Mr. Wei Shao is a partner of the global law firm Dentons and the National China Service Co-chair at Dentons Canada LLP, specializing in international business transactions. He has over 30 years of experience in mergers and acquisitions, corporate and project financing, complex corporate and commercial transactions, and advising clients on business negotiations, policy and regulatory matters, and government relations, across industries including natural resources, technologies, manufacturing, financial services, infrastructure and real estate. Mr. Shao has represented Chinese investors and entrepreneurs, sovereign and investment funds, private and public companies, and major state-owned enterprises in significant transactions in or through Canada, and has advised Canadian and international companies in their investments in China. As an investor and director, he has co-founded or been involved in agri-food, energy, manufacturing and infrastructure projects, and data center opportunities in North America. Mr. Shao is also an accredited interpreter of the United Nations and the federal government of Canada and has served on the boards or in advisory roles for organizations including the British Columbia Government Advisory Council on China, the Vancouver Police Board, the Vancouver Aquarium, S.U.C.C.E.S.S., and the Jack Austin International Center of the Beedie Business School at Simon Fraser University. Mr. Shao also currently serves as a director, and as a member of the audit, compensation and nominating and corporate governance committees, of China Gold International Resources Corp., a publicly listed company in Canada and Hong Kong.

Reconstitution of Board Committees

In connection with the foregoing changes, on May 13, 2026, the Board reconstituted its standing committees, in each case with effect from the same date, as follows: the Audit Committee shall consist of Ms. Yuet Yiu Charissa Miu (Chairperson and Audit Committee Financial Expert), Mr. Ho Chuen Shin and Mr. Wei Shao; the Compensation Committee shall consist of Mr. Ho Chuen Shin (Chairperson), Ms. Yuet Yiu Charissa Miu and Mr. Wei Shao; and the Nominating and Corporate Governance Committee shall consist of Mr. Wei Shao (Chairperson), Ms. Yuet Yiu Charissa Miu and Mr. Ho Chuen Shin.

Following the foregoing changes, the Company’s Board is composed of seven (7) directors, comprising three (3) executive directors and four (4) independent directors.
