Item 8.01. Other Events.

As previously reported, on October 10, 2025, Healthcare AI Acquisition Corp. (the “Company”) held its general annual meeting (the “Meeting”). At the Meeting, the proposal was approved for the Company to extend the date by which it has to complete a business combination from October 14, 2025 on a month-to-month basis until October 14, 2026 (each month so extended, the “Extended Date”), by depositing into the trust account $0.10 per non-redeemed public share for each monthly extension deposited into the Company’s trust account (the “Trust Account”), held by Continental Stock Transfer & Trust Company.

In connection with the shareholders’ vote at the Meeting, 23,033 shares were tendered for redemption. As a result, approximately $292,422.64 (approximately $ 12.69 per share) will be removed from the Company’s Trust Account to pay such holders, without taking into account additional allocation of payments to cover any tax obligation of the Company since that date. Following redemptions, the Company will have 5,520,077 Class A Shares outstanding, and one Class B Share outstanding, and approximately $1,643,828.35 will remain in the Company’s Trust Account.
