Canadian Imperial Bank of Commerce (CIBC) provides a product supplement dated June 4, 2026 describing terms for Senior Global Medium-Term Notes linked to equity Market Measures (indices, ETFs, common stock or ADSs). The notes are U.S. dollar senior unsecured obligations of CIBC, repayable at maturity subject to issuer credit risk, and may provide a variable maturity payment tied to the performance of one or more Market Measures as specified in an applicable pricing supplement.

The supplement explains key mechanics: calculation days and Closing Value conventions, the role and powers of the calculation agent (initially CIBC), Market Disruption Event definitions and postponement procedures (including the concept of a final disrupted calculation day), anti-dilution and reorganization adjustments (Adjustment Factor rules), book-entry DTC settlement, rounding rules, and that the notes will not be exchange-listed. Specific issuance terms (principal, pricing date, coupon, maturity, Market Measure selection) will appear in separate pricing supplements.

The supplement emphasizes that payments depend on Market Measure performance, that the securities are unsecured senior debt payable in U.S. dollars, and that the specific terms (face amount, pricing date, calculation days, coupons, and maturity payment mechanics) will be set in each applicable pricing supplement.

Canadian Imperial Bank of Commerce (CIBC) supplements its prospectus to describe senior unsecured notes linked to one or more exchange-traded funds (Funds). The supplement (Registration No. 333-294072) dated June 4, 2026 explains that payments depend on the Reference Asset’s Closing Price on designated Valuation Dates, are subject to CIBC credit risk, and may result in loss of principal. Terms such as postponement for Market Disruption Events, limited anti-dilution adjustments, possible physical delivery of Fund shares, and discretionary hedging/market-making by the bank are described. The notes will be U.S. dollar denominated, typically not listed, and holders have no ownership or voting rights in the Funds. Potential purchasers are directed to the applicable pricing supplement, this underlying supplement, and accompanying prospectus materials for specific terms and risks.

Canadian Imperial Bank of Commerce filed a Stock-Linked Underlying Supplement dated June 4, 2026 describing terms and risks for senior unsecured notes linked to one or more equity securities or ADRs (the “Reference Asset”). The supplement explains structure risks, credit exposure to CIBC, limited liquidity, the Bank’s initial estimated value methodology, anti-dilution rules, Market Disruption Event mechanics and potential physical delivery or cash settlement.

The calculation agent (expected to be the Bank) has broad discretion over Valuation Dates, Market Disruption Event determinations, anti-dilution adjustments and substitutions; certain postponements can extend payment or maturity dates by specified Business Days. The supplement emphasizes purchasers may lose some or all principal and that secondary-market liquidity is unlikely.

The document lists indices that may underlie future issuances (including the Dow Jones Industrial Average, EURO STOXX 50, FTSE 100, Hang Seng, MSCI family and others), warns that notes are unsecured and not FDIC/CDIC insured, and states that payments depend on CIBC creditworthiness and on values observed on specified Valuation Dates.

The document highlights key investor risks including credit risk, potential lack of market liquidity, FATCA withholding, benchmark transition risks (EURIBOR, SOFR), currency‑exchange risks for non‑U.S. dollar notes and the possibility that certain notes may be bail-inable and converted into common shares under Canadian bank resolution powers.

Notes are automatically called if the Index on a semi-annual Call Observation Date is at or above the Initial Level; if not called, principal at maturity depends on the Final Level relative to the Buffer Level (80% of Initial Level). If the Final Level is below the Buffer Level, losses accrue at a 1.25% rate per 1.00% decline beyond the 20% buffer with a 125% downside leverage factor.

The Leverage Factor is 127.10%. The notes pay no interest, are unsecured senior debt, are not insured deposits, and are subject to CIBC credit risk. The Bank’s initial estimated value was $949.20 per note, below the price to public of $1,000.00, and selling compensation is disclosed.
