Canadian Imperial Bank of Commerce Trigger Autocallable Contingent Yield Notes$2,500,000 Notes Linked to the S&P 500®Index due on July 19, 2029 Investment Description These Trigger Autocallable Contingent Yield Notes (the ‘‘Notes’’) are senior unsecured debt securities issued by Canadian Imperial Bank of Commerce (“CIBC”) with returns linked to theS&P 500®Index (the “Underlying”). The Notes will rank equally with all of our other unsecured and unsubordinated debt obligations. CIBC will pay a quarterly Contingent Coupon if theClosing Level of the Underlying on the applicable Coupon Determination Date (including the Final Valuation Date) is equal to or greater than the Coupon Barrier. Otherwise, no coupon willbe paid for the quarter. CIBC will automatically call the Notes if the Closing Level of the Underlying on any quarterly Call Observation Date, commencing on July 19, 2027 is equal to orgreater than the 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 further amountswill be owed to you under the Notes. If the Notes are not called prior to maturity and the Final Level is equal to or greater than the Downside Threshold, CIBC will pay you a cash paymentat maturity equal to the principal amount of your Notes plus the final Contingent Coupon. If the Final Level is less than the Downside Threshold, CIBC will pay you less than the fullprincipal amount, if anything, resulting in a loss on your initial investment that is proportionate to the negative performance of the Underlying over the term of the Notes, and you may loseup 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 exposedto the market risk of the Underlying on each Coupon Determination Date. Generally, the higher the Contingent Coupon 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. Any payments on the Notes, including any repayment of principal, are subject to thecreditworthiness of CIBC. If CIBC were to default on its payment obligations, you may not receive any amounts owed to you under the Notes and you could lose your entireinvestment.
