The securities may not be an appropriate investment for investors who:

The considerations identified above are not exhaustive. Whether or not the securities are an appropriate investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisors have carefully considered the appropriateness of an investment in the securities in light of your particular circumstances. You should also review carefully the “Selected Risk Considerations” herein and the “Risk Factors” in the accompanying underlying supplement for risks related to an investment in the securities.

Market Linked Securities— Leveraged Upside Participation and Fixed Percentage Buffered Downside Principal at Risk Securities Linked to the SPDR® Dow Jones® Industrial Average ETF Trust due August 2, 2029

On the Stated Maturity Date, you will receive a cash payment per security (the Maturity Payment Amount) calculated as follows:

Market Linked Securities— Leveraged Upside Participation and Fixed Percentage Buffered Downside Principal at Risk Securities Linked to the SPDR® Dow Jones® Industrial Average ETF Trust due August 2, 2029

The securities have complex features and investing in the securities will involve risks not associated with an investment in conventional debt securities. Some of the risks that apply to an investment in the securities are summarized below, but we urge you to read the more detailed explanation of the risks relating to the securities generally in the “Risk Factors” beginning on page S-1 of the accompanying underlying supplement, page S-1 of the prospectus supplement and page 1 of the prospectus. You should reach an investment decision only after you have carefully considered with your advisors the appropriateness of an investment in the securities in light of your particular circumstances.

Risks Relating To The Structure Of The Securities

If The Ending Price Is Less Than The Threshold Price, You Will Lose Some, And Possibly Up To 85%, Of The Face Amount Of Your Securities At Maturity.

We will not repay you a fixed amount on the securities on the Stated Maturity Date. The Maturity Payment Amount will depend on the direction of and percentage change in the Ending Price of the Fund relative to the Starting Price and the other terms of the securities. Because the price of the Fund will be subject to market fluctuations, the Maturity Payment Amount may be more or less, and possibly significantly less, than the face amount of your securities.

If the Ending Price is less than the Threshold Price, the Maturity Payment Amount will be less than the face amount and you will have 1-to-1 downside exposure to the decrease in the price of the Fund in excess of the Buffer Amount, resulting in a loss of 1% of the face amount for every 1% decrease in the price of the Fund in excess of the Buffer Amount. The Threshold Price is 85% of the Starting Price. As a result, if the Ending Price is less than the Threshold Price, you will lose some, and possibly up to 85%, of the face amount at maturity. This is the case even if the price of the Fund is greater than or equal to the Starting Price or the Threshold Price at certain times during the term of the securities.

Even if the Ending Price is greater than the Starting Price, the Maturity Payment Amount may only be slightly greater than the face amount, and your yield on the securities may be less than the yield you would earn if you bought a traditional interest-bearing debt security of CIBC or another issuer with a similar credit rating with the same Stated Maturity Date.

No Periodic Interest Will Be Paid On The Securities.

No periodic interest will be paid on the securities. However, if the securities were classified for U.S. federal income tax purposes as contingent payment debt instruments rather than prepaid cash-settled derivative contracts, you would be required to accrue interest income over the term of your securities. See “Summary of U.S. Federal Income Tax Consequences” in this pricing supplement and “Material U.S. Federal Income Tax Consequences” in the underlying supplement.

The Stated Maturity Date May Be Postponed If The Calculation Day Is Postponed.

The Calculation Day will be postponed if the originally scheduled Calculation Day is not a Trading Day or if the calculation agent determines that a Market Disruption Event has occurred or is continuing on that day. If such a postponement occurs, the Stated Maturity Date will be the later of (i) the initial Stated Maturity Date and (ii) three Business Days after the Calculation Day, as postponed.

The Securities Are Riskier Than Securities With A Shorter Term.

The securities are relatively long-dated. Therefore, many of the risks of the securities are heightened as compared to securities with a shorter term, as you will be subject to those risks for a longer period of time. In addition, the value of a longer-dated security is typically less than the value of an otherwise comparable security with a shorter term.

Risk Relating To The Credit Risk Of CIBC

The Securities Are Subject To The Credit Risk Of Canadian Imperial Bank of Commerce.

The securities are our obligations exclusively and are not, either directly or indirectly, an obligation of any third party. Any amounts payable under the securities are subject to our creditworthiness, and you will have no ability to pursue the Fund or any securities held by the Fund for payment. As a result, our actual and perceived creditworthiness and actual or anticipated decreases in our credit ratings may affect the value of the securities and, in the event we were to default on our obligations, you may not receive any amounts owed to you under the terms of the securities. See “Description of Senior Debt Securities—Events of Default” in the prospectus.

Market Linked Securities— Leveraged Upside Participation and Fixed Percentage Buffered Downside Principal at Risk Securities Linked to the SPDR® Dow Jones® Industrial Average ETF Trust due August 2, 2029

Risks Relating To The Estimated Value Of The Securities And Any Secondary Market

Our Estimated Value Of The Securities Will Be Lower Than The Original Offering Price Of The Securities.

Our estimated value is only an estimate using several factors. The original offering price of the securities will exceed our estimated value because costs associated with selling and structuring the securities, as well as hedging the securities, are included in the original offering price of the securities. See “The Estimated Value of the Securities” in this pricing supplement.

Our Estimated Value Does Not Represent Future Values Of The Securities And May Differ From Others’ Estimates.

Our estimated value of the securities is determined by reference to our internal pricing models when the terms of the securities are set. This estimated value is based on market conditions and other relevant factors existing at that time and our assumptions about market parameters, which can include volatility, dividend rates, interest rates and other factors. Different pricing models and assumptions could provide valuations for the securities that are greater than or less than our estimated value. In addition, market conditions and other relevant factors in the future may change, and any assumptions may prove to be incorrect. On future dates, the value of the securities could change significantly based on, among other things, changes in market conditions, our creditworthiness, interest rate movements and other relevant factors, which may impact the price, if any, at which Wells Fargo Securities or any other person would be willing to buy securities from you in secondary market transactions. See “The Estimated Value of the Securities” in this pricing supplement.

Our Estimated Value Is Not Determined By Reference To Credit Spreads For Our Conventional Fixed-Rate Debt.

The internal funding rate used in the determination of our estimated value generally represents a discount from the credit spreads for our conventional fixed-rate debt. If we were to use the interest rate implied by our conventional fixed-rate credit spreads, we would expect the economic terms of the securities to be more favorable to you. Consequently, our use of an internal funding rate would have an adverse effect on the terms of the securities and any secondary market prices of the securities. See “The Estimated Value of the Securities” in this pricing supplement.

The Estimated Value Of The Securities Will Not Be An Indication Of The Price, If Any, At Which Wells Fargo Securities Or Any Other Person May Be Willing To Buy The Securities From You In The Secondary Market.

The price, if any, at which Wells Fargo Securities or any of its affiliates may purchase the securities in the secondary market will be based on Wells Fargo Securities’ proprietary pricing models and will fluctuate over the term of the securities as a result of changes in the market and other factors described in the next risk factor. Any such secondary market price for the securities will also be reduced by a bid-offer spread, which may vary depending on the aggregate face amount of the securities to be purchased in the secondary market transaction, and the expected cost of unwinding any related hedging transactions. Unless the factors described in the next risk factor change significantly in your favor, any such secondary market price for the securities will likely be less than the original offering price.

If Wells Fargo Securities or any of its affiliates makes a secondary market in the securities at any time up to the Issue Date or during the six-month period following the Issue Date, the secondary market price offered by Wells Fargo Securities or any of its affiliates will be increased by an amount reflecting a portion of the costs associated with selling, structuring, hedging and issuing the securities that are included in the original offering price. Because this portion of the costs is not fully deducted upon issuance, any secondary market price offered by Wells Fargo Securities or any of its affiliates during this period will be higher than it would be if it were based solely on Wells Fargo Securities’ proprietary pricing models less the bid-offer spread and hedging unwind costs described above. The amount of this increase in the secondary market price will decline steadily to zero over this six-month period. If you hold the securities through an account at Wells Fargo Securities or one of its affiliates, we expect that this increase will also be reflected in the value indicated for the securities on your brokerage account statement. If you hold your securities through an account at a broker-dealer other than Wells Fargo Securities or any of its affiliates, the value of the securities on your brokerage account statement may be different than if you held your securities at Wells Fargo Securities or any of its affiliates.

The Value Of The Securities Prior To Maturity Will Be Affected By Numerous Factors, Some Of Which Are Related In Complex Ways.

The value of the securities prior to maturity will be affected by the then-current price of the Fund, interest rates at that time and a number of other factors, some of which are interrelated in complex ways. The effect of any one factor may be offset or magnified by the effect of another factor. The following factors, among others, are expected to affect the value of the securities: Fund performance; volatility of the Fund; economic and other conditions generally; interest rates; dividend yields on the Fund or the securities held by the Fund; our credit ratings or credit spreads; and time remaining to maturity. When we refer to the “value” of your security, we mean the value you could receive for your security if you are able to sell it in the open market before the Stated Maturity Date.

Market Linked Securities— Leveraged Upside Participation and Fixed Percentage Buffered Downside Principal at Risk Securities Linked to the SPDR® Dow Jones® Industrial Average ETF Trust due August 2, 2029

You should understand that the impact of one of the factors specified above, such as a change in interest rates, may offset some or all of any change in the value of the securities attributable to another factor, such as a change in the price of the Fund. Because numerous factors are expected to affect the value of the securities, changes in the price of the Fund may not result in a comparable change in the value of the securities.

The Securities Will Not Be Listed On Any Securities Exchange And We Do Not Expect A Trading Market For The Securities To Develop.

The securities will not be listed on any securities exchange. Although Wells Fargo Securities and/or its affiliates may purchase the securities from holders, they are not obligated to do so and are not required to make a market for the securities. There can be no assurance that a secondary market will develop for the securities. Because we do not expect that any market makers will participate in a secondary market for the securities, the price at which you may be able to sell your securities is likely to depend on the price, if any, at which Wells Fargo Securities and/or its affiliates are willing to buy your securities.

If a secondary market does exist, it may be limited. Accordingly, there may be a limited number of buyers if you decide to sell your securities prior to maturity. This may affect the price you receive upon such sale. Consequently, you should be willing to hold the securities to maturity.

Risks Relating To The Fund

Anti-dilution Adjustments Relating To The Shares Of The Fund Do Not Address Every Event That Could Affect Such Shares.

An Adjustment Factor, as described in the accompanying product supplement, will be used to determine the Ending Price of the Fund. The Adjustment Factor will be adjusted by the calculation agent for certain events affecting the shares of the Fund. However, the calculation agent will not make an adjustment for every event that could affect such shares. If an event occurs that does not require the calculation agent to adjust the Adjustment Factor, the value of the securities may be adversely affected.

The Performance Of The Fund May Not Correlate With The Performance Of Its Underlying Index As Well As The Net Asset Value Per Share Of The Fund, Especially During Periods Of Market Volatility.

Although the Fund is designed to track the performance of its Underlying Index, the performance of the Fund and that of its Underlying Index generally will vary due to, for example, transaction costs, management fees, certain corporate actions, and timing variances. Moreover, it is also possible that the performance of a Fund may not fully replicate or may, in certain circumstances, diverge significantly from the performance of its Underlying Index. This could be due to, for example, the Fund not holding all or substantially all of the underlying assets included in the Underlying Index and/or holding assets that are not included in the Underlying Index, the temporary unavailability of certain securities in the secondary market, the performance of any derivative instruments held by the Fund, differences in trading hours between the Fund (or the underlying assets held by the Fund) and the Underlying Index, or due to other circumstances. This variation in performance is called the “tracking error,” and, at times, the tracking error may be significant.

In addition, because the shares of a Fund are traded on a securities exchange and are subject to market supply and investor demand, the market price of one share of the Fund may differ from its net asset value per share; shares of the Fund may trade at, above, or below its net asset value per share.

During periods of market volatility, securities held by a Fund may be unavailable in the secondary market, market participants may be unable to calculate accurately the net asset value per share of the Fund and the liquidity of the Fund may be adversely affected. This kind of market volatility may also disrupt the ability of market participants to create and redeem shares of the Fund. Further, market volatility may adversely affect, sometimes materially, the prices at which market participants are willing to buy and sell shares of the Fund. As a result, under these circumstances, the market value of shares of the Fund may vary substantially from the net asset value per share of the Fund.

For the foregoing reasons, the performance of a Fund may not match the performance of its Underlying Index over the same period. Because of this variance, the return on the securities, to the extent dependent on the performance of the Fund, may not be the same as an investment directly in the securities, commodities, or other assets included in the Underlying Index or the same as a debt security with a return linked to the performance of the Underlying Index.

Risks Relating To Conflicts Of Interest

We Or One Of Our Affiliates Will Be The Calculation Agent And, As A Result, Potential Conflicts Of Interest Could Arise.

We or one of our affiliates will be the calculation agent for purposes of determining, among other things, the Starting Price and the Ending Price, calculating the Maturity Payment Amount, determining whether adjustments should be made to the Adjustment Factor,

Market Linked Securities— Leveraged Upside Participation and Fixed Percentage Buffered Downside Principal at Risk Securities Linked to the SPDR® Dow Jones® Industrial Average ETF Trust due August 2, 2029

determining whether a Market Disruption Event has occurred on the scheduled Calculation Day, which may result in postponement of the Calculation Day; determining the Fund Closing Price of the Fund if the Calculation Day is postponed to the last day to which it may be postponed and a Market Disruption Event occurs on that day; if publication of the Fund is discontinued, selecting a successor or, if no successor is available, determining the Fund Closing Price on the Calculation Day; and determining whether to adjust the Fund Closing Price of the Fund on the Calculation Day in the event of certain changes in or modifications to the Fund or the Underlying Index. Although the calculation agent will exercise its judgment in good faith when performing its functions, potential conflicts of interest may exist between the calculation agent and you.

Our Economic Interests And Those Of Any Dealer Participating In The Offering Of Securities Will Potentially Be Adverse To Your Interests.

You should be aware of the following ways in which our economic interests and those of any dealer participating in the distribution of the securities, which we refer to as a “participating dealer,” will potentially be adverse to your interests as an investor in the securities. In engaging in certain of the activities described below, our affiliates or any participating dealer or its affiliates may take actions that may adversely affect the value of and your return on the securities, and in so doing they will have no obligation to consider your interests as an investor in the securities. Our affiliates or any participating dealer or its affiliates may realize a profit from these activities even if investors do not receive a favorable investment return on the securities.

Risks Relating To Tax

The U.S. Federal Tax Consequences Of An Investment In The Securities Are Unclear.

There is no direct legal authority regarding the proper U.S. federal tax treatment of the securities, and we do not plan to request a ruling from the U.S. Internal Revenue Service (the “IRS”). Consequently, significant aspects of the tax treatment of the securities are uncertain, and the IRS or a court might not agree with the treatment of the securities as prepaid cash-settled derivative contracts. If the IRS were successful in asserting an alternative treatment of the securities, the tax consequences of the ownership and disposition of the securities might be materially and adversely affected. As described under “Material U.S. Federal Income Tax Consequences” in the underlying supplement, the U.S. Treasury Department and the IRS released a notice requesting comments on various issues regarding the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. Any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, including the character and timing of income or loss and the degree, if any, to which income realized by non-U.S. persons should be subject to withholding tax, possibly with retroactive effect.

Both U.S. and non-U.S. persons considering an investment in the securities should review carefully “Summary of U.S. Federal Income Tax Consequences” in this pricing supplement and “Material U.S. Federal Income Tax Consequences” in the underlying supplement and consult their tax advisors regarding the U.S. federal tax consequences of an investment in the securities (including possible alternative treatments and the issues presented by the notice), as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

There Can Be No Assurance That The Canadian Federal Income Tax Consequences Of An Investment In The Securities Will Not Change In The Future.

There can be no assurance that Canadian federal income tax laws, the judicial interpretation thereof, or the administrative policies and assessing practices of the Canada Revenue Agency will not be changed in a manner that adversely affects investors. For a discussion of the Canadian federal income tax consequences of investing in the securities, please read the section entitled “Certain Canadian Federal Income Tax Considerations” in this pricing supplement as well as the section entitled “Material Income Tax Consequences—Canadian Taxation” in the accompanying prospectus. You should consult your tax advisor with respect to your own particular situation. 

Market Linked Securities— Leveraged Upside Participation and Fixed Percentage Buffered Downside Principal at Risk Securities Linked to the SPDR® Dow Jones® Industrial Average ETF Trust due August 2, 2029

The payout profile, return table and examples below illustrate the Maturity Payment Amount for a $1,000 face amount security on a hypothetical offering of securities under various scenarios, with the assumptions set forth in the table below. The terms used for purposes of these hypothetical examples do not represent the actual Starting Price or Threshold Price. The hypothetical Starting Price of $100.00 has been chosen for illustrative purposes only and does not represent the actual Starting Price. The actual Starting Price and Threshold Price will be determined on the Pricing Date and will be set forth under “Terms of the Securities” above. For historical data regarding the actual Closing Prices of the Fund, see the historical information set forth herein. The payout profile, return table and examples below assume that an investor purchases the securities for $1,000 per security. These examples are for purposes of illustration only and the values used in the examples may have been rounded for ease of analysis. The actual Maturity Payment Amount and resulting pre-tax total rate of return will depend on the actual terms of the securities.

Hypothetical Returns

Market Linked Securities— Leveraged Upside Participation and Fixed Percentage Buffered Downside Principal at Risk Securities Linked to the SPDR® Dow Jones® Industrial Average ETF Trust due August 2, 2029

Hypothetical Examples

Example 1. The Maturity Payment Amount is greater than the face amount:

Because the hypothetical Ending Price is greater than the hypothetical Starting Price, the Maturity Payment Amount per security would be equal to:

$1,000 + ($1,000 × Fund Return × Upside Participation Rate)

$1,000 + ($1,000 × 10.00% × 120.70%)

= $1,120.70

On the Stated Maturity Date, you would receive $1,120.70 per security.

Example 2. The Maturity Payment Amount is equal to the face amount:

Because the hypothetical Ending Price is less than the hypothetical Starting Price, but not by more than the Buffer Amount, you would not lose any of the face amount of your securities.

On the Stated Maturity Date, you would receive $1,000.00 per security.

Example 3. The Maturity Payment Amount is less than the face amount:

Market Linked Securities— Leveraged Upside Participation and Fixed Percentage Buffered Downside Principal at Risk Securities Linked to the SPDR® Dow Jones® Industrial Average ETF Trust due August 2, 2029

Because the hypothetical Ending Price is less than the hypothetical Starting Price by more than the Buffer Amount, you would lose a portion of the face amount of your securities and receive the Maturity Payment Amount equal to:

$1,000 + [$1,000 × (Fund Return + Buffer Amount)]

$1,000 + [ $1,000 × (-50.00% + 15%)]

= $650.00

On the Stated Maturity Date, you would receive $650.00 per security.

Market Linked Securities— Leveraged Upside Participation and Fixed Percentage Buffered Downside Principal at Risk Securities Linked to the SPDR® Dow Jones® Industrial Average ETF Trust due August 2, 2029

The Fund is an exchange-traded fund. The Fund seeks to replicate, before fees and expenses, the price and yield performance of the Dow Jones Industrial Average^® (the “Underlying Index”). The Underlying Index is composed of 30 “blue-chip” U.S. stocks. The Fund trades on the NYSE Arca under the ticker symbol “DIA.”

Information provided to or filed with the SEC by the Fund pursuant to the Securities Act of 1933 and the Investment Company Act of 1940 can be located by reference to SEC file numbers 333-31247 and 811-09170, respectively, through the SEC’s website at http://www.sec.gov. See “Reference Sponsors and Fund Descriptions—The SPDR^® Dow Jones^® Industrial Average ETF Trust” beginning on page S-47 of the accompanying underlying supplement for additional information about the Fund.

Historical Data

We obtained the Closing Prices of the Fund in the graph below from Bloomberg Finance L.P. (“Bloomberg”) without independent verification. The historical performance of the Fund should not be taken as an indication of future performance, and no assurances can be given as to the Closing Price of the Fund on the Calculation Day. We cannot give you assurance that the performance of the Fund will result in the return of any of your investment.

The following graph sets forth daily Closing Prices of the Fund for the period from January 1, 2018 to September 27, 2023. The Closing Price of the Fund on September 27, 2023 was $335.43.

Market Linked Securities— Leveraged Upside Participation and Fixed Percentage Buffered Downside Principal at Risk Securities Linked to the SPDR® Dow Jones® Industrial Average ETF Trust due August 2, 2029

The estimated value of the securities 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 securities, valued using our internal funding rate for structured debt described below, and (2) the derivative or derivatives underlying the economic terms of the securities. The estimated value does not represent a minimum price at which Wells Fargo Securities or any other person would be willing to buy your securities in any secondary market (if any exists) at any time. The internal funding rate used in the determination of the Bank’s 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 securities as well as the higher issuance, operational and ongoing liability management costs of the securities in comparison to those costs for our conventional fixed-rate debt. For additional information, see “Risk Factors—Our Estimated Value Is 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 securities 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 estimated value of the securities is determined when the terms of the securities are set based on market conditions and other relevant factors and assumptions existing at that time. See “Risk Factors—Our Estimated Value Does Not Represent Future Values Of The Securities And May Differ From Others’ Estimates” in this pricing supplement.

The Bank’s estimated value of the securities will be lower than the original offering price of the securities because costs associated with selling, structuring and hedging the securities are included in the original offering price of the securities. These costs include the selling commissions paid to 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 securities and the estimated cost of hedging our obligations under the securities. 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 securities. See “Risk Factors—Our Estimated Value of the Securities Will Be Lower Than The Original Offering Price Of The Securities” in this pricing supplement.

Market Linked Securities— Leveraged Upside Participation and Fixed Percentage Buffered Downside Principal at Risk Securities Linked to the SPDR® Dow Jones® Industrial Average ETF Trust due August 2, 2029

The following discussion is a brief summary of the material U.S. federal income tax considerations relating to an investment in the securities. The following summary is not complete and is both qualified and supplemented by, or in some cases supplements, the discussion entitled “Material U.S. Federal Income Tax Consequences” in the underlying supplement, which you should carefully review prior to investing in the securities.

The U.S. federal income tax consequences of your investment in the securities are uncertain. No statutory, judicial or administrative authority directly discusses how the securities 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 securities as prepaid cash-settled derivative contracts. By purchasing the securities, you agree to treat the securities in this manner for all U.S. federal income tax purposes. If this treatment is respected, subject to the discussion in the underlying supplement concerning the potential application of the “constructive ownership” rules under Section 1260 of the Code, you should generally recognize capital gain or loss upon the sale, exchange, redemption or payment on maturity in an amount equal to the difference between the amount you receive at such time and the amount that you paid for your securities. Such gain or loss should generally be long-term capital gain or loss if you have held your securities for more than one year. Non-U.S. Holders should consult the section entitled “Material U.S. Federal Income Tax Consequences—Non-U.S. Holders” in the underlying supplement.

The expected characterization of the securities is not binding on the IRS or the courts. Thus, it is possible that the IRS would seek to characterize your securities in a manner that results in tax consequences to you that are different from those described above or in the accompanying underlying supplement. Such alternate treatments could include a requirement that a holder accrue ordinary income over the life of the securities or treat all gain or loss at maturity as ordinary gain or loss. For a more detailed discussion of certain alternative characterizations with respect to your securities and certain other considerations with respect to your investment in the securities, 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 securities for U.S. federal income tax or other tax purposes.

Based on our determination that the securities are not “delta-one” instruments, Non-U.S. Holders should not be subject to withholding on dividend equivalent payments, if any, under the securities. 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 securities 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 securities 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 security 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 security; (c) does not use or hold and is not deemed to use or hold the security 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 security; (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 security 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 Proposals, 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 proposed paragraph 18.4(3)(b) of the Canadian Tax Act contained in the proposals to amend the Canadian Tax Act released by the Minister of Finance (Canada) on April 29, 2022 with respect to “hybrid mismatch arrangements” (the “Hybrid Mismatch Proposals”). Investors should note that the Hybrid Mismatch Proposals are in consultation form, are highly complex, and there remains significant uncertainty as to their interpretation and application. There can be no assurance that the Hybrid Mismatch Proposals will be enacted in their current form, or at all.

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 securities 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 securities, interest payable on the securities 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 security 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 securities to a person with whom they are not dealing at arm’s length for purposes of the Canadian Tax Act.
