$1,000

If the Final Index Value is less than the Trigger Level:

$1,000 × Index Performance Factor

Under these circumstances, the Payment at Maturity will be less than the Stated Principal Amount of $1,000 and will

represent a loss of more than 35% , and possibly all, of your investment.

If the Underlying Index depreciates 75%, investors would lose 75% of their principal and receive only $250.00 per Trigger PLUS at maturity, or 25% of the Stated Principal Amount.

The following discussion is a brief summary of the material U.S. federal income tax considerations relating to an investment in the Trigger PLUS. The following summary is not complete and is both qualified and supplemented by (although to the extent inconsistent supersedes) the discussion entitled “Material U.S. Federal Income Tax Consequences” in the underlying supplement, which you should carefully review prior to investing in the Trigger PLUS. It applies only to those U.S. Holders who are not excluded from the discussion of United States Taxation in the accompanying prospectus.

The U.S. federal income tax considerations of your investment in the Trigger PLUS are uncertain. No statutory, judicial or administrative authority directly discusses how the Trigger PLUS should be treated for U.S. federal income tax purposes. In the opinion of our tax counsel, Mayer Brown LLP, it would generally be reasonable to treat the Trigger PLUS as prepaid derivative contracts. Pursuant to the terms of the Trigger PLUS, you agree to treat the Trigger PLUS in this manner for all U.S. federal income tax purposes. If this treatment is respected, you should generally recognize capital gain or loss upon the sale, exchange, cash redemption or payment upon maturity in an amount equal to the difference between the amount you receive in such transaction and the amount that you paid for your Trigger PLUS. Such gain or loss should generally be treated as long-term capital gain or loss if you have held your Trigger PLUS for more than one year.

The expected characterization of the Trigger PLUS is not binding on the U.S. Internal Revenue Service (the “IRS”) or the courts. It is possible that the IRS would seek to characterize the Trigger PLUS in a manner that results in tax consequences to you that are different from those described above or in the accompanying underlying supplement. For a more detailed discussion of certain alternative characterizations with respect to the Trigger PLUS and certain other considerations with respect to an investment in the Trigger PLUS, you should consider the discussion set forth in “Material U.S. Federal Income Tax Consequences” of the underlying supplement. We are not responsible for any adverse consequences that you may experience as a result of any alternative characterization of the Trigger PLUS for U.S. federal income tax or other tax purposes.

With respect to the discussion in the underlying supplement regarding “dividend equivalent” payments, the IRS has issued a notice that provides that withholding on dividend equivalent payments will not apply to specified ELIs that are not delta-one instruments and that are issued before January 1, 2027. Based on our determination that the Trigger PLUS are not “delta-one” instruments, Non-U.S. Holders should not be subject to withholding on dividend equivalent payments, if any, under the Trigger PLUS. For a more detailed discussion of withholding responsibilities on dividend equivalent payments, Non-U.S. Holders should consult the section entitled “Material U.S. Federal Income Tax Consequences—Non-U.S. Holders” in the underlying supplement and consult with their own tax advisors.

You should consult your tax advisor as to the tax consequences of such characterization and any possible alternative characterizations of the Trigger PLUS for U.S. federal income tax purposes. You should also consult your tax advisor concerning the U.S. federal income tax and other tax consequences of your investment in the Trigger PLUS in your particular circumstances, including the application of state, local or other tax laws and the possible effects of changes in federal or other tax laws.

In the opinion of Blake, Cassels & Graydon LLP, our Canadian tax counsel, the following summary describes the principal Canadian federal income tax considerations under the Income Tax Act (Canada) and the regulations thereto (the “Canadian Tax Act”) generally applicable at the date hereof to a purchaser who acquires beneficial ownership of a Trigger PLUS pursuant to this pricing supplement and who for the purposes of the Canadian Tax Act and at all relevant times: (a) is neither resident nor deemed to be resident in Canada; (b) deals at arm’s length with CIBC and any transferee resident (or deemed to be resident) in Canada to whom the purchaser disposes of the Trigger PLUS; (c) does not use or hold and is not deemed to use or hold the Trigger PLUS in, or in the course of, carrying on a business in Canada; (d) is entitled to receive all payments (including any interest and principal) made on the Trigger PLUS; (e) is not a, and deals at arm’s length with any, “specified shareholder” of CIBC for purposes of the thin capitalization rules in the Canadian Tax Act; and (f) is not an entity in respect of which CIBC or any transferee resident (or deemed to be resident) in Canada

to whom the purchaser disposes of, loans or otherwise transfers the Trigger PLUS is a “specified entity”, and is not a “specified entity” in respect of such a transferee, in each case, for purposes of the Hybrid Mismatch Rules, as defined below (a “Non-Resident Holder”). Special rules which apply to non-resident insurers carrying on business in Canada and elsewhere are not discussed in this summary.

This summary assumes that no amount paid or payable to a holder described herein will be the deduction component of a “hybrid mismatch arrangement” under which the payment arises within the meaning of the rules in the Canadian Tax Act with respect to “hybrid mismatch arrangements” (the “Hybrid Mismatch Rules”). Investors should note that the Hybrid Mismatch Rules are highly complex and there remains significant uncertainty as to their interpretation and application.

This summary is supplemental to and should be read together with the description of material Canadian federal income tax considerations relevant to a Non-Resident Holder owning Trigger PLUS under “Material Income Tax Consequences—Canadian Taxation” in the accompanying prospectus and a Non-Resident Holder should carefully read that description as well.

This summary is of a general nature only and is not intended to be, nor should it be construed to be, legal or tax advice to any particular Non-Resident Holder. Non-Resident Holders are advised to consult with their own tax advisors with respect to their particular circumstances.

Based on Canadian tax counsel’s understanding of the Canada Revenue Agency’s administrative policies and having regard to the terms of the Trigger PLUS, interest payable on the Trigger PLUS should not be considered to be “participating debt interest” as defined in the Canadian Tax Act and accordingly, a Non-Resident Holder should not be subject to Canadian non-resident withholding tax in respect of amounts paid or credited or deemed to have been paid or credited by CIBC on a Trigger PLUS as, on account of or in lieu of payment of, or in satisfaction of, interest.

Non-Resident Holders should consult their own advisors regarding the consequences to them of a disposition of the Trigger PLUS to a person with whom they are not dealing at arm’s length for purposes of the Canadian Tax Act.

Pursuant to the terms of a distribution agreement, CIBCWM will purchase the Trigger PLUS from CIBC for distribution to Morgan Stanley Wealth Management. Morgan Stanley Wealth Management and its financial advisors will collectively receive from CIBCWM a fixed sales commission of $30.00 for each Trigger PLUS they sell. In addition, Morgan Stanley Wealth Management will receive a structuring fee of $5.00 for each Trigger PLUS. The costs included in the original issue price of the Trigger PLUS will also include a fee paid by CIBCWM to LFT Securities, LLC, an entity in which an affiliate of Morgan Stanley Wealth Management has an ownership interest for providing certain electronic platform services with respect to this offering. CIBCWM is our affiliate, and is deemed to have a conflict of interest under FINRA Rule 5121. In accordance with FINRA Rule 5121, CIBCWM may not make sales in this offering to any of its discretionary accounts without the prior written approval of the customer.

We will deliver the Trigger PLUS against payment therefor in New York, New York on a date that is more than one business day following the Pricing Date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Trigger PLUS on any date prior to one business day before delivery will be required to specify alternative settlement arrangements to prevent a failed settlement.

The Bank may use this pricing supplement in the initial sale of the Trigger PLUS. In addition, CIBCWM or another of the Bank’s affiliates may use this pricing supplement in market-making transactions in any Trigger PLUS after their initial sale. Unless CIBCWM or we inform you otherwise in the confirmation of sale, this pricing supplement is being used by CIBCWM in a market-making transaction.

While CIBCWM may make markets in the Trigger PLUS, it is under no obligation to do so and may discontinue any market-making activities at any time without notice. See the section titled “Supplemental Plan of Distribution (Conflicts of Interest)” in the accompanying prospectus supplement.

The price at which you purchase the Trigger PLUS includes costs that the Bank or its affiliates expect to incur and profits that the Bank or its affiliates expect to realize in connection with hedging activities related to the Trigger PLUS. These costs and profits will likely reduce the secondary market price, if any secondary market develops, for the Trigger PLUS. As a result, you may experience an immediate and substantial decline in the market value of your Trigger PLUS on the Original Issue Date.

The Bank’s initial estimated value of the Trigger PLUS set forth on the cover of this pricing supplement is equal to the sum of the values of the following hypothetical components: (1) a fixed-income debt component with the same maturity as the Trigger PLUS, valued using our internal funding rate for structured debt described below, and (2) the derivative or derivatives underlying the economic terms of the Trigger PLUS. The Bank’s initial estimated value does not represent a minimum price at which CIBCWM or any other person would be willing to buy your Trigger PLUS in any secondary market (if any exists) at any time. The internal funding rate used in the determination of the Bank’s initial estimated value generally represents a discount from the credit spreads for our conventional fixed-rate debt. The discount is based on, among other things, our view of the funding value of the Trigger PLUS as well as the higher issuance, operational and ongoing liability management costs of the Trigger PLUS in comparison to those costs for our conventional fixed-rate debt. For additional information, see “Risk Factors—The Bank’s initial estimated value of the Trigger PLUS was not determined by reference to credit spreads for our conventional fixed-rate debt” in this pricing supplement. The value of the derivative or derivatives underlying the economic terms of the Trigger PLUS is derived from the Bank’s or a third party hedge provider’s internal pricing models. These models are dependent on inputs such as the traded market prices of comparable derivative instruments and on various other inputs, some of which are market-observable, and which can include volatility, dividend rates, interest rates and other factors, as well as assumptions about future market events and/or environments. Accordingly, the Bank’s initial estimated value of the Trigger PLUS was determined when the terms of the Trigger PLUS were set based on market conditions and other relevant factors and assumptions existing at that time. See “Risk Factors—The Bank’s initial estimated value does not represent future values of the Trigger PLUS and may differ from others’ estimates” in this pricing supplement.

The Bank’s initial estimated value of the Trigger PLUS is lower than the initial issue price of the Trigger PLUS because costs associated with selling, structuring and hedging the Trigger PLUS are included in the initial issue price of the Trigger PLUS. These costs include the selling commissions paid to CIBCWM and other affiliated or unaffiliated dealers, the projected profits that our hedge counterparties, which may include our affiliates, expect to realize for assuming risks inherent in hedging our obligations under the Trigger PLUS and the estimated cost of hedging our obligations under the Trigger PLUS. Because hedging our obligations entails risk and may be influenced by market forces beyond our control, this hedging may result in a profit that is more or less than expected, or it may result in a loss. We or one or more of our affiliates will retain any profits realized in hedging our obligations under the Trigger PLUS. See “Risk Factors—The Bank’s initial estimated value of the Trigger PLUS is lower than the initial issue price (price to public) of the Trigger PLUS” in this pricing supplement.
