We refer to the above issue of Notes, described in more detail in the Final Terms (the "Final Terms"), as signed by CIBC, as well as the Terms and Conditions of the Notes (the "Conditions"), which are supplemented by the Final Terms and which are set out in the Prospectus dated 24 January 2025 (the "Prospectus").

Correction of Manifest Error

The following changes are made to the Final Terms for a manifest error for the "Knock-in Barrier". The product of 65% and the Initial Index Level was miscalculated and now has been replaced as follows:-

On Page 17 and 22 of the Final Terms:

In all other respects, the Final Terms is correct and all other terms and conditions of the Final Terms remain unchanged. Capitalised terms used but not defined herein shall have the same meaning ascribed thereto in the Final Terms.

The amended Final Terms have been submitted to the National Storage Mechanism and will shortly be available for inspection at: https://data.fca.org.uk/#/nsm/nationalstoragemechanism.
