Departure of Director

On February 13, 2026, Jim (Jimmy Yee-Ming) Wu resigned from the Board of Directors of the Company, effective immediately. Mr. Wu’s resignation was not the result of any disagreement with the Company on any matter relating to the Company’s operations, policies, or practices. Mr. Wu’s directorship was scheduled to be up for election at the Company’s next annual general meeting of shareholders.

Appointment of Interim Director

On April 2, 2026, the Board appointed Hiroto Kobayashi as a director of the Company on an interim basis, to fill the vacancy created by Mr. Wu’s resignation, effective immediately. Mr. Kobayashi will serve until the Company’s next annual general meeting of shareholders, at which time his appointment will be subject to ratification by the Company’s shareholders.

Mr. Kobayashi, age 62, is an original co-founder of Mediagene Inc., where he served as Director and Chief Visionary Officer, and presently serves as Chief Content Officer for the Company’s Japan operations. Mr. Kobayashi helped launch the Japanese edition of WIRED Magazine in 1994 and co-founded Mediagene in 1998. Over the course of his career, he has launched a variety of print and online media properties, including GIZMODO Japan. Since 2017, Mr. Kobayashi has served as an official Japan partner for TOA, an international technology conference held in Berlin, and currently produces programs and fieldwork projects focused on circular economy, biodiversity, and local government-private sector partnerships.

The Board has not determined that Mr. Kobayashi is independent under Nasdaq Listing Rule 5605(a)(2). Mr. Kobayashi will not serve on any committee of the Board at this time.

There are no arrangements or understandings between Mr. Kobayashi and any other person pursuant to which he was selected as a director. There are no family relationships between Mr. Kobayashi and any director or executive officer of the Company.
