Amendment to Quarterly Report (Form 10-Q/A)

The purpose of this Amendment No. 1 (this "Amendment") to our Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2026, originally filed with the Securities and Exchange Commission (the "SEC") on August 11, 2026 (the "Original Report"), is solely to correct an inadvertent clerical omission of the introductory language in paragraph 4 regarding internal control over financial reporting and paragraph 4(b) from Exhibit 31.1, Certification of the Principal Executive Officer, and Exhibit 31.2, Certification of the Principal Financial Officer (the "CFO Certification"), filed with the Original Report. The omission was limited to the text of the certification and did not reflect any change in management's assessment of the Company's disclosure controls and procedures or internal control over financial reporting. This Amendment consists solely of the cover page, this Explanatory Note, Item 6 of Part II, the signature page hereto, and the certifications filed as Exhibits 31.1 and 31.2. Because no financial statements are contained in this Amendment, paragraph 3 of each certification has been omitted. No other changes or updates have been made to the Original Report, including to the Company's financial statements, results of operations or other disclosures in the Original Report, and this Amendment does not reflect subsequent events occurring after the original filing date of the Original Report. Accordingly, this Amendment should be read in conjunction with the Original Report and our other filings with the SEC.

The Original Report was certified by Matthew McDonnell, who served as the principal financial officer of Anteris Technologies Global Corp. (the "Company") at the time of its filing. Following the appointment of Brent Moen as the Company's principal financial officer, the revised CFO Certification filed as Exhibit 31.2 to the Amendment is being executed by Brent Moen in that capacity.
