Canadian Imperial Bank of Commerce (CIBC) is offering Senior Global Medium-Term Notes: Contingent Coupon (with Memory) Barrier Notes linked to the worst-performing of the common stock of Advanced Micro Devices, Inc., ServiceNow, Inc. and Palantir Technologies Inc.. Each note has a principal amount of $1,000 and a term of approximately three years. The notes may pay monthly contingent coupons of at least $16.70 per $1,000 (1.67% per payment, equivalent to 20.04% per annum) only when the worst-performing reference stock on a Coupon Determination Date is at or above its Coupon Barrier Price (50% of its Initial Price). Missed coupons carry forward and can be paid later if barrier conditions are met. At maturity the Payment at Maturity depends on the Final Price of the worst-performing reference stock: if at or above the Principal Barrier Price (50% of Initial Price), you receive principal plus the final contingent coupon; if below, you suffer a dollar-for-dollar loss equal to the Percentage Change of that worst-performing stock (up to 100% principal loss). The notes are unsecured obligations of the Bank, not FDIC- or CDIC-insured, not listed, and subject to the Bank’s credit risk.
