Correction to Appendix 3Y

7 January 2026 – Weebit Nano Ltd ( ASX: WBT , Weebit or Company ) wishes to advise a correction to the Appendix 3Y for Mr David Perlmutter released on 5 January 2026.

The Appendix 3Y lodged on 5 January 2026 incorrectly noted that the number of securities held prior to the change included 1,063,750 ordinary shares held by IBI Trust Management as trustee for David Perlmutter ( IBI Trust ) when in fact it included 1,603,750 ordinary shares held by IBI Trust. This error followed through to the number of securities held after the change which incorrectly stated 1,151,250 ordinary shares held by IBI Trust rather than the correct number of 1,691,250 ordinary shares.

The attached Appendix 3Y corrects the errors.

• ENDS -

Authorised for release by the Board of Weebit Nano Limited.
