Canadian Imperial Bank of Commerce Capped Buffer GEARS$9,779,660 Notes Linked to the S&P 500® Index due on May 2, 2028 Investment Description These Capped Buffer GEARS (the “Notes”) are senior unsecured debt securities issued by Canadian Imperial Bank of Commerce (“CIBC”) with returns linked to the S&P500®Index (the “Underlying”). The Notes will rank equally with all of our other unsecured and unsubordinated debt obligations.If the Underlying Return is positive, CIBCwill pay the principal amount at maturity plus a return equal to 2.00 (the “Upside Gearing”) multiplied by the Underlying Return, up to the Maximum Gain. If the UnderlyingReturn is zero or negative, but the Final Level is greater than or equal to the Downside Threshold, CIBC will pay the full principal amount at maturity. However, if theUnderlying Return is negative and the Final Level is less than the Downside Threshold, CIBC will pay less than the full principal amount at maturity and you will lose 1% ofthe principal amount of your Notes for every 1% decline in the level of the Underlying in excess of the Buffer. Investing in the Notes involves significant risks. The Notes do not pay any interest. You may lose up to 90% of your principal amount. Any payment on the Notes,including any repayment of principal at maturity, is subject to the creditworthiness of CIBC. If CIBC were to default on its payment obligations, you may not receiveany amounts owed to you under the Notes and you could lose your entire investment.
