Item 1.01 Entry into a Material Definitive Agreement.

On May 22, 2026, Anteris Technologies Global Corp. (the "Company") entered into a Sales Agreement (the "Agreement") with TD Securities (USA) LLC ("TD Cowen"). Pursuant to the terms of the Agreement, the Company may offer and sell through TD Cowen, from time to time and at its sole discretion, shares of the Company's common stock, par value of $0.0001 per share (the "Common Stock"), having an aggregate offering price of up to $250,000,000 (the "Offering").

Subject to the terms and conditions of the Agreement, TD Cowen has agreed to use its commercially reasonable efforts, consistent with its normal trading and sales practices and applicable law and regulations and the rules of the Nasdaq Stock Market LLC, and the Australian Securities Exchange, to sell from time to time the Common Stock so designated by the Company, acting as agent and/or as principal, in accordance with the Company's instructions (including any price, time or size limits or other customary parameters or conditions the Company may impose). The Company cannot provide any assurances that it will issue any Common Stock pursuant to the Agreement. The sales of the Common Stock under the Agreement will be made by any method permitted by law that is deemed an "at the market" offering as defined in Rule 415(a)(4) under the Securities Act of 1933 (the "Securities Act"), including sales made through the Nasdaq Global Market ("Nasdaq"), or in negotiated transactions, including block trades. The Agreement provides that the commission payable to TD Cowen for sales of Common Stock with respect to which TD Cowen acts as sales agent shall be 3.0% of the gross proceeds from the sale of such Common Stock sold pursuant to the Agreement. The Agreement contains customary representations and warranties of the parties and indemnification and contribution provisions under which the Company and TD Cowen have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act and the Securities Exchange Act of 1934. The Company will also reimburse TD Cowen for certain expenses incurred in connection with the Agreement. The Offering will terminate upon the earlier of (i) the sale of all shares of Common Stock subject to the Agreement and (ii) the termination of the Agreement as permitted therein. The Company and TD Cowen may each terminate the Agreement in their sole discretion at any time upon ten days' prior notice. In addition, TD Cowen may terminate the Agreement at any time upon the occurrence of certain specified events, including a material adverse effect on the Company, a failure by the Company to perform its obligations under the Agreement, or a suspension or limitation of trading in the Common Stock on Nasdaq.

The Company currently intends to use any net proceeds from the Offering primarily for the ongoing development of its DurAVR^® Transcatheter Heart Valve System, with the remaining for working capital and other general corporate purposes determined from time to time.
