Canadian Imperial Bank of Commerce is offering $16,286,000 of Digital Basket‑Linked Notes due April 13, 2029. Each note has a $1,000 principal amount and the notes are linked to a weighted basket of five equity indices with an initial basket level of 100.

The notes pay no interest; maturity cash is based on the basket return versus the 100 initial level, with a threshold settlement amount of $1,288.10 (per $1,000) if the final basket level is at or above the initial level, a full principal return if the final level declines up to 15.00%, and a reduced recovery (using a buffer rate of approximately 117.65%) if the final level declines by more than 15.00%. The Bank's estimated value at pricing was $989.90 per note versus the issue price of $1,000. Payments are unsecured and subject to the issuer's credit risk.

A 15.00% buffer protects investors from losses up to that decline; losses beyond a 15.00% decline are passed to holders and could total the full principal. The bank’s estimated value at issuance is expected to be between $976.20 and $996.20 per note, which is lower than the issue price. Payments at maturity depend on the S&P 500® closing level on the determination date; all payments are unsecured and subject to CIBC credit risk.

If the final underlier level is below the initial level, investors suffer proportional losses and could lose their entire investment. The notes do not bear interest, are unsecured obligations of CIBC, are not FDIC‑ or CDIC‑insured, and will not be listed on a U.S. exchange. CIBC’s estimated value on the trade date is expected to be between $971.00 and $991.00 per note.
