**SUPPLEMENT TO THE DEFINITIVE PROXY STATEMENT** 

**FOR THE ANNUAL MEETING OF STOCKHOLDERS** 

**TO BE HELD ON DECEMBER 1, 2025** 

November 10, 2025

On October 14, 2025, Benitec Biopharma Inc. (the "Company") filed its definitive proxy statement (the "Proxy Statement") with the Securities and Exchange Commission in connection with the Company's 2025 Annual Meeting of Stockholders scheduled to be held on December 1, 2025 (the "Annual Meeting").

As previously disclosed, subsequent to the filing of the Proxy Statement, the Board of Directors (the "Board") of the Company appointed Dr. Sharon Mates to serve as a director of the Board, effective as of November 3, 2025. Dr. Mates was appointed as a Class I member of the Board with a term lasting until the Company's 2026 annual meeting of stockholders. In connection with the appointment of Dr. Mates, the Board also approved an increase in the size of the Board from six to seven members.

The Board has determined that Dr. Mates is independent in accordance with applicable rules of the Nasdaq Stock Market LLC and the Company's Corporate Governance Guidelines.

In connection with Dr. Mates's appointment to the Board, the Board announced on November 3, 2025 its approval of the grant of options to purchase 28,517 shares of the Company's common stock ("Common Stock") to Dr. Mates under the Company's 2020 Equity and Incentive Compensation Plan (the "Equity Plan") to have an exercise price equal to the closing price as quoted on the Nasdaq stock exchange on November 5, 2025, which was $15.78 per share. The Options will vest in full on the earlier of immediately prior to the 2026 annual meeting of stockholders and the first anniversary of the Grant Date. The Options are subject to the terms and conditions of the Equity Plan and the Company's standard form of stock option award agreement. Dr. Mates will also be entitled to the compensation provided to the Company's non-employee directors as described in the Proxy Statement. Dr. Mates will also enter into the Company's standard indemnification agreement for members of the Board, the form of which is attached as Exhibit 10.6 to the Company's Annual Report on Form 10-K filed on September 22, 2025.

There have been no transactions, nor are there any currently proposed transactions, in which the Company was or is to be a participant and which Dr. Mates, or any member of her immediate family was or is to have a material interest, that would require disclosure under Item 404(a) of Regulation S-K.

***Voting Matters***

You are not being asked to vote on or ratify the election of Dr. Mates at the Annual Meeting. Dr. Mates, as a Class I director, is not a nominee for election at the Annual Meeting. Accordingly, there is no change to Proposal 1: Election of Directors included in the Proxy Statement.

If you have already submitted your vote, you do not need to take any further action. Information on how to vote your shares and how to change your vote or revoke your proxy is contained in the Proxy Statement.
