On October 27, 2026, Mr. Marc Seelenfreund notified Core AI Holdings, Inc., a British Columbia, Canada corporation (the “Company”), of his resignation as a member of the Company’s Board of Directors (the “Board”) and from all committees of the Board on which he served, effective immediately. Mr. Seelenfreund’s resignation did not result from any disagreement with the Company on any matter relating to the Company’s operations, policies or practices. The Company thanks Mr. Seelenfreund for his service and contributions to the Company.

On October 28, 2026, the Board appointed Mr. Haggai Ravid as a director of the Company, effective immediately, to fill the vacancy created by Mr. Seelenfreund’s resignation. Mr. Ravid will serve until the Company’s next annual general meeting of shareholders or until his successor is duly elected or appointed. The Board has determined that Mr. Ravid qualifies as an independent director under the Nasdaq listing rules.

From December 2022 to December 2024, he served as Chief Financial Officer of Seamless Group Inc. (Nasdaq: CURR). From 2006 to 2022, he served as Chief Executive Officer of Cukierman & Company Investment House Ltd., a cross-border advisory firm based in Israel. Earlier in his career, Mr. Ravid held partnership roles at MBI in Tel Aviv and Twin Triangle Financial in Los Angeles. He also served as a loan officer and credit committee member at Bank Leumi in Los Angeles. Mr. Ravid holds an MBA from Rutgers University and an undergraduate degree from the Hebrew University.
