The Notes will rankequally with all of our other unsecured and unsubordinated debt obligations. CIBC will pay a quarterly Contingent Coupon if the Closing Level of each Underlying on theapplicable Coupon Determination Date (including the Final Valuation Date) is equal to or greater than its Coupon Barrier. Otherwise, no coupon will be paid for the quarter.CIBC will automatically call the Notes if the Closing Level of each Underlying on any quarterly Call Observation Date, commencing on March 5, 2026, is equal to or greaterthan its Initial Level. If the Notes are called, CIBC will pay you the principal amount of your Notes plus the Contingent Coupon for the applicable quarter, and no furtheramounts will be owed to you under the Notes. The Underlying with the lowest Underlying Return is the “Least Performing Underlying.” If the Notes are not called prior tomaturity and the Final Level of the Least Performing Underlying is equal to or greater than its Downside Threshold, CIBC will pay you a cash payment at maturity equal tothe principal amount of your Notes plus the final Contingent Coupon. If the Final Level of the Least Performing Underlying is less than its Downside Threshold, CIBC will payyou less than the full principal amount, if anything, resulting in a loss on your initial investment that is proportionate to the negative performance of the Least PerformingUnderlying over the term of the Notes, and you may lose up to 100% of your principal amount. Investing in the Notes involves significant risks. CIBC may not pay any Contingent Coupons on the Notes. You may lose some or all of your principal amount.You will be exposed to the market risk of each Underlying on each Coupon Determination Date and any decline in the level of one Underlying may negativelyaffect your return and will not be offset or mitigated by a lesser decline or any increase in the level of any other Underlying. Generally, the higher the ContingentCoupon Rate on a Note, the greater the risk of loss on that Note. The contingent repayment of principal only applies if you hold the Notes to maturity orautomatic call. Any payments on the Notes, including any repayment of principal, are subject to the creditworthiness of CIBC. If CIBC were to default on itspayment obligations, you may not receive any amounts owed to you under the Notes and you could lose your entire investment.
