On June 10, 2026, Core AI Holdings, Inc. (the “Company”) entered into a securities purchase agreement (the “Purchase Agreement”) with an institutional investor (the “Purchaser”), pursuant to which the Purchaser agreed, subject to the satisfaction of certain conditions contained in the Purchase Agreement, to purchase the Company’s securities consisting of up to 1,969,444 of the Company’s common shares, no par value (the “Shares”), and pre-funded warrants (the “Pre-Funded Warrants”) to purchase up to 3,975,000 common shares (the “Warrant Shares”), at a combined purchase price of $0.90 per Share and $0.89999 per Pre-Funded Warrant.

The issuance of the Shares, the Pre-Funded Warrants and the common shares underlying the Pre-Funded Warrants (the “Offering”) is pursuant to the Purchase Agreement and the Company’s Prospectus Supplement (the “Prospectus Supplement”) dated June 10, 2026 and filed with the Securities and Exchange Commission (the “SEC”) pursuant to Rule 424(b)(5). The Pre-Funded Warrants are immediately exercisable at a nominal exercise price of $0.00001 per share and will expire when exercised in full. The Pre-Funded Warrants also have a cashless exercise provision as set forth in the Purchase Agreement and described in the Prospectus Supplement.

The Closing will occur on June 11, 2026 and the Company issued up to 1,969,444 Shares and Pre-Funded Warrants to purchase up to 3,975,000 common shares for aggregate gross proceeds of approximately $5.4 million, before deducting placement agent fees and other offering expenses payable by the Company.

The Purchase Agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company, including for liabilities arising under the Securities Act of 1933, as amended, other obligations of the parties and termination provisions. The representations, warranties and covenants contained in the Purchase Agreement were made only for the purpose of such agreement and as of specific dates, were solely for the benefit of the parties to the Purchase Agreement and may be subject to limitations agreed upon by the contracting parties.

The Company entered into a placement agency agreement (the “Placement Agency Agreement”) with D. Boral Capital LLC (the “Placement Agent”) on June 10, 2026, pursuant to which the Placement Agent agreed to serve as the exclusive placement agent for the Company, on a reasonable best efforts basis, in connection with the Offering. The Company has agreed to pay the Placement Agent an aggregate cash fee equal to 7.0% of the gross proceeds received in the Offering and to reimburse certain expenses incurred by the Placement Agent in connection with the Offering.

Pursuant to the terms of the Purchase Agreement and the Placement Agency Agreement, from the date of the Purchase Agreement until thirty (30) days after the Closing Date, neither the Company nor any of its subsidiaries may (i) issue, enter into any agreement to issue or announce the issuance or proposed issuance of any common shares or common share equivalents or (ii) file any registration statement or any amendment or supplement thereto, in each case other than as contemplated by the Purchase Agreement, subject to certain exceptions for exempt issuances, including issuances pursuant to employee equity incentive plans and existing outstanding securities.
