NOTICE IS HEREBY GIVEN that the 2025 Annual Meeting of Stockholders (the “Annual Meeting”) of Anteris Technologies Global Corp., a Delaware corporation (the “Company”), will be held on December 3, 2025, at 5:00 p.m. Central time (being 9:00 a.m. AEST December 4, 2025). You can attend the Annual Meeting in person at InterContinental Brisbane, 190 Elizabeth Street, Brisbane, Queensland 4000 Australia, or via the live webcast on the Internet at www.virtualshareholdermeeting.com/AVR2025, where you can participate, vote, and submit questions during the Annual Meeting.

For purposes of attendance at the Annual Meeting, all references in this Proxy Statement to “present in person” shall include virtually present at the Annual Meeting. Only stockholders of record at the close of business on October 30, 2025 (being 7:00 a.m. AEST on October 31, 2025), are entitled to notice of, and to vote at, the Annual Meeting and any postponement or adjournment thereof. Holders of CHESS Depositary Interests (“CDIs”) of the Company at that time will be entitled to receive notice of, and to attend the Annual Meeting. CDI holders may vote in advance of the Annual Meeting by instructing CHESS Depositary Nominees Pty Ltd (“CDN”) to vote on their behalf by either completing and signing their CDI Voting Instruction Form or logging on to www.investorvote.com.au and entering the 6-digit control number found on their CDI Voting Instruction Form.

As further described in the proxy materials for the Annual Meeting, you may attend the Annual Meeting in person or via the live webcast on the Internet at www.virtualshareholdermeeting.com/AVR2025. You may vote by telephone, Internet, or mail prior to the Annual Meeting. While we encourage you to vote in advance of the Annual Meeting, unless you are a holder of CDIs, you may also vote electronically or in person and submit questions relating to meeting matters during the Annual Meeting (subject to time restrictions), regardless of whether you are attending in person or virtually. CDI holders will only be able to ask questions during the Annual Meeting if they are attending in person.

To be admitted to the Annual Meeting at www.virtualshareholdermeeting.com/AVR2025, stockholders must enter the 15-digit control number found on your proxy card. Holders of CDIs that plan to attend the Annual Meeting via live webcast will need to do so as guests.
