Canadian Imperial Bank of Commerce is offering $10,050,000 aggregate principal amount of 4.50% Callable Notes due June 16, 2028. The Notes accrue interest at 4.50% per annum, payable semi‑annually on June 16 and December 16, commencing December 16, 2026, and will be issued on June 16, 2026.

The Bank may redeem the Notes in whole (but not in part) on the Optional Redemption Date of June 16, 2027 at a Redemption Price equal to 100% of principal plus accrued and unpaid interest. The Notes are senior, unsecured and not deposit insured; they are bail-inable debt securities subject to conversion under the CDIC Act.

Canadian Imperial Bank of Commerce (CIBC) is offering Autocallable Strategic Accelerated Redemption Securities® linked to one or more equity indices or exchange-traded funds. These are unsecured senior notes that do not pay interest and may not return principal at maturity. Each unit, unless otherwise specified in the term sheet, has a principal amount of $10. The notes will be automatically called if the Market Measure meets or exceeds a specified Call Level on an Observation Date, producing a Call Amount equal to principal plus a Call Premium. If not called, payment at maturity depends on the Ending Value relative to a Threshold Value; if the Ending Value is below the Threshold Value you face 1-to-1 downside exposure and could lose some or all principal. The product supplement explains calculation agent discretion, Market Disruption Events, anti-dilution adjustments for Underlying Funds, tax redemption mechanics, and material risks including issuer credit risk and potential illiquidity.

Canadian Imperial Bank of Commerce describes a public offering program of Accelerated Return Notes ("ARNs"), senior unsecured notes that return a multiple of positive performance of an equity Market Measure up to a capped amount and expose holders to 1-to-1 downside on negative performance.

The product supplement explains that ARNs pay no interest, are unsecured obligations of the issuer, will generally have a $10 principal per unit unless the term sheet states otherwise, and that specific offering terms (Market Measure, Capped Value, Participation Rate, Price Multiplier, Maturity Valuation Period) will be set in each term sheet.

Canadian Imperial Bank of Commerce offers Accelerated Return Notes ("ARNs") linked to one or more equity securities or ADRs. ARNs are unsecured senior notes with no periodic interest; typical unit principal is $10. Returns depend on the Market Measure’s performance from a Starting Value to an Ending Value, with a Participation Rate of 300% (unless otherwise set in the term sheet) and a contractual Capped Value (set on the pricing date). ARNs expose holders to full 1-to-1 downside in the Market Measure and are subject to the issuer’s credit risk. BofA Securities is expected to serve as calculation agent and agent for distribution. ARNs may be linked to a single Underlying Stock or a Basket (Starting Value for a Basket = 100); anti-dilution, market-disruption, tax-redemption, and other adjustments are governed by the calculation agent’s formulas. Tax treatment is uncertain under U.S. federal law; Canadian tax changes may permit early redemption.

CIBC received Toronto Stock Exchange approval for a new normal course issuer bid, allowing the bank to repurchase and cancel up to 30 million common shares. This represents about 3.3% of its 912,835,441 issued and outstanding common shares as of May 31, 2026.

The maximum 30 million shares under the new bid, combined with 20 million shares already repurchased under the prior program, equal about 5.5% of CIBC’s 912,564,072-share public float. The previous bid, begun in September 2025 and completed in May 2026, retired 20 million shares at an average price of $129.68 for a total of $2.6 billion.

Specific issuance terms (principal, pricing date, coupon, maturity, Market Measure selection) will appear in separate pricing supplements.

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.
