The notes do not bear interest. The amount that you will be paid on your notes on the stated maturity date (July 7, 2022, subject to adjustment) is based on the performance of the S&P 500® Index (the “underlier”) as measured from the trade date to and including the determination date (July 5, 2022, subject to adjustment). If the final underlier level on the determination date is greater than the initial underlier level (3,483.34, which was the closing level of the underlier on the trade date), the return on your notes will be positive, subject to the maximum settlement amount ($1,215.41 for each $1,000 principal amount of your notes). If the final underlier level declines by up to 12.50% from the initial underlier level, you will receive the principal amount of your notes. If the final underlier level declines by more than 12.50% from the initial underlier level, the return on your notes will be negative. You could lose your entire investment in the notes.

To determine your payment at maturity, we will calculate the underlier return, which is the percentage increase or decrease in the final underlier level from the initial underlier level. On the stated maturity date, for each $1,000 principal amount of your notes, you will receive an amount in cash equal to:

·                  if the underlier return is positive (i.e. the final underlier level is greater than the initial underlier level), the sum of (i) $1,000 plus (ii) the product of (a) $1,000 times (b) 1.3 times (c) the underlier return, subject to the maximum settlement amount; or

·                  if the underlier return is zero or negative but not below -12.50% (i.e. the final underlier level is equal to or less than the initial underlier level, but not by more than 12.50%), $1,000; or

·                  if the underlier return is negative and is below -12.50% (i.e. the final underlier level is less than the initial underlier level by more than 12.50%), the sum of (i) $1,000 plus (ii) the product of (a) approximately 114.29% times (b) the sum of the underlier return plus 12.50% times (c) $1,000. This amount will be less than $1,000 and may be zero.

The notes have complex features and investing in the notes involves risks not associated with an investment in conventional debt securities. See “Additional Risk Factors Specific to Your Notes” beginning on page PRS-10 of this Pricing Supplement and “Risk Factors” beginning on page S-1 of the accompanying Underlying Supplement.

Our estimated value of the notes on the trade date, based on our internal pricing models, is $989.40 per note. The estimated value is less than the initial issue price of the notes. See “The Bank’s Estimated Value of the Notes” in this Pricing Supplement.

The notes are unsecured obligations of Canadian Imperial Bank of Commerce and all payments on the notes are subject to the credit risk of Canadian Imperial Bank of Commerce. The notes will not constitute deposits insured by the Canada Deposit Insurance Corporation, the U.S. Federal Deposit Insurance Corporation or any other government agency or instrumentality of Canada, the United States or any other jurisdiction. The notes are not bail-inable debt securities (as defined on page 6 of the prospectus). The notes will not be listed on any U.S. securities exchange or interdealer quotation system.

Neither the United States Securities and Exchange Commission (the “SEC”) nor any state or provincial securities commission has approved or disapproved of these securities or determined if this Pricing Supplement or the accompanying Underlying Supplement, Prospectus Supplement or Prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The issue price, agent’s commission and net proceeds listed above relate to the notes we will sell initially. We may decide to sell additional notes after the trade date, at issue prices and with agent’s commissions and net proceeds that differ from the amounts set forth above. The return (whether positive or negative) on your investment will depend in part on the issue price you pay for your notes.

CIBC World Markets Corp. or one of our other affiliates may use this Pricing Supplement in a market-making transaction in a note after its initial sale. Unless we or our agent informs the purchaser otherwise in the confirmation of sale, this Pricing Supplement is being used in a market-making transaction.

We will deliver the notes in book-entry form through the facilities of The Depository Trust Company (“DTC”) on October 22, 2020 against payment in immediately available funds.

You should be willing to forgo:

·                  gains greater than a maximum settlement amount of 121.541% of the principal amount in exchange for (i) 1.3x leveraged upside participation if the underlier return is positive and (ii) a buffer against loss of principal in the event of a decline of up to 12.50% in the final underlier level relative to the initial underlier level; and

·                  interest payments and be willing to risk losing your entire investment for the potential to earn 130.00% of any positive underlier return up to a maximum settlement amount of 121.541% of the principal amount

Your maximum return on your notes will not be greater than 21.541%, and you could lose all or a substantial portion of your investment if the underlier return is negative and is below -12.50%.

At maturity, for each $1,000 principal amount, the investor will receive (in each case as a percentage of the principal amount):

·                  if the final underlier level is greater than 100.00% of the initial underlier level, 100.00% plus 130.00% times the underlier return, subject to a maximum settlement amount of 121.541%; or

·                  if the final underlier level is equal to or less than the initial underlier level, but not by more than 12.50%, 100.00%; or

·                  if the final underlier level is less than the initial underlier level by more than 12.50%, 100.00% minus approximately 1.1429% for every 1.00% that the final underlier level has declined below 87.50% of the initial underlier level.

If the final underlier level is less than the initial underlier level by more than 12.50%, the return on the notes will be negative and the investor could lose their entire investment in the notes.

Market disruption event:   With respect to any given trading day, any of the following will be a market disruption event with respect to the underlier:

·                  a suspension, absence or material limitation of trading in underlier stocks (as defined below) constituting 20% or more, by weight, of the underlier on their respective primary markets, in each case for more than two consecutive hours of trading or during the one-half hour before the close of trading in that market, as determined by the calculation agent in its sole discretion,

·                  a suspension, absence or material limitation of trading in option or futures contracts, if available, relating to the underlier or to underlier stocks constituting 20% or more, by weight, of the underlier in their respective primary markets for those contracts, in each case for more than two consecutive hours of trading or during the one-half hour before the close of trading in that market, as determined by the calculation agent in its sole discretion, or

·                  underlier stocks constituting 20% or more, by weight, of the underlier, or option or futures contracts, if available, relating to the underlier or to underlier stocks constituting 20% or more, by weight, of the underlier do not trade on what were the respective primary markets for those underlier stocks or contracts, as determined by the calculation agent in its sole discretion,

and, in the case of any of these events, the calculation agent determines in its sole discretion that the event could materially interfere with the ability of us or any of our affiliates or a similarly situated party to unwind all or a material portion of a hedge that could be effected with respect to the notes. For more information about hedging by us and/or any of our affiliates, see “Use of Proceeds and Hedging” in the accompanying Underlying Supplement.

The following events will not be market disruption events with respect to the underlier:

·                  a limitation on the hours or numbers of days of trading, but only if the limitation results from an announced change in the regular business hours of the relevant market, and

·                  a decision to permanently discontinue trading in the option or futures contracts relating to the underlier or to any underlier stock.

For this purpose, an “absence of trading” in the primary securities market on which an underlier stock, or on which option or futures contracts, if available, relating to the underlier or to any underlier stock are traded will not include any time when that market is itself closed for trading under ordinary circumstances. In contrast, a suspension or limitation of trading in an underlier stock or in option or futures contracts, if available, relating to the underlier or to any underlier stock in the primary market for that stock or those contracts, by reason of:

·                  a price change exceeding limits set by that market,

·                  an imbalance of orders relating to that underlier stock or those contracts, or

·                  a disparity in bid and ask quotes relating to that underlier stock or those contracts,

will constitute a suspension or material limitation of trading in that underlier stock or those contracts in that market.

SUPPLEMENTAL TERMS OF THE NOTES

For purposes of the notes offered by this Pricing Supplement, all references to each of the following terms used in the accompanying Underlying Supplement will be deemed to refer to the corresponding term used in this Pricing Supplement, as set forth in the table below:

PRS-6

Capped Leveraged Buffered S&P 500® Index-Linked Notes due July 7, 2022

HYPOTHETICAL EXAMPLES

The following table and chart are provided for purposes of illustration only. They should not be taken as an indication or prediction of future investment results and merely are intended to illustrate the impact that the various hypothetical final underlier levels on the determination date could have on the cash settlement amount at maturity assuming all other variables remain constant.

The examples below are based on a range of final underlier levels that are entirely hypothetical; the underlier level on any day throughout the life of the notes, including the final underlier level on the determination date, cannot be predicted. The underlier has been highly volatile in the past — meaning that the underlier level has changed considerably in relatively short periods — and its performance cannot be predicted for any future period.

The information in the following examples reflects hypothetical rates of return on the offered notes assuming that they are purchased on the original issue date at the principal amount and held to the stated maturity date. If you sell your notes in a secondary market prior to the stated maturity date, your return will depend upon the market value of your notes at the time of sale, which may be affected by a number of factors that are not reflected in the table below, such as interest rates, the volatility of the underlier and the creditworthiness of CIBC. In addition, the estimated value of your notes at the time the terms of your notes were set on the trade date (as determined by reference to pricing models used by CIBC) is less than the original issue price of your notes. For more information on the estimated value of your notes, see “Additional Risk Factors Specific to Your Notes — The Bank’s Estimated Value of the Notes Is Lower Than the Original Issue Price (Price to Public) of the Notes” in this Pricing Supplement and “The Bank’s Estimated Value of the Notes” in this Pricing Supplement. The information in the following hypothetical examples also reflects the key terms and assumptions in the box below.

The actual performance of the underlier over the life of your notes, as well as the cash settlement amount payable at maturity, if any, may bear little relation to the hypothetical examples shown below or to the historical underlier levels shown elsewhere in this Pricing Supplement. For information about the historical levels of the underlier during recent periods, see “The Underlier — Historical Closing Levels of the Underlier” below. Before investing in the offered notes, you should consult publicly available information to determine the levels of the underlier between the date of this Pricing Supplement and the date of your purchase of the offered notes.

Also, the hypothetical examples shown below do not take into account the effects of applicable taxes. Because of the U.S. tax treatment applicable to your notes, tax liabilities could affect the after-tax rate of return on your notes to a comparatively greater extent than the after-tax return on the underlier stocks.

The levels in the left column of the table below represent hypothetical final underlier levels and are expressed as percentages of the initial underlier level. The amounts in the right column represent the hypothetical cash settlement amounts, based on the corresponding hypothetical final underlier level, and are expressed as percentages of the principal amount of a note (rounded to the nearest one-thousandth of a percent). Thus, a hypothetical cash settlement amount of 100.000% means that the value of the cash payment that we would deliver for each $1,000 of the outstanding principal amount of the offered notes on the stated maturity date would equal 100.000% of the principal amount of a note, based on the corresponding hypothetical final underlier level and the assumptions noted above.

Capped Leveraged Buffered S&P 500® Index-Linked Notes due July 7, 2022

If, for example, the final underlier level were determined to be 25.000% of the initial underlier level, the cash settlement amount that we would deliver on your notes at maturity would be approximately 28.571% of the principal amount of your notes, as shown in the table above. As a result, if you purchased your notes on the original issue date at the principal amount and held them to the stated maturity date, you would lose approximately 71.429% of your investment (if you purchased your notes at a premium to principal amount you would lose a correspondingly higher percentage of your investment). If the final underlier level were determined to be 0.000% of the initial underlier level, you would lose your entire investment in the notes. In addition, if the final underlier level were determined to be 200.000% of the initial underlier level, the cash settlement amount that we would deliver on your notes at maturity would be capped at the maximum settlement amount, or 121.541% of each $1,000 principal amount of your notes, as shown in the table above. As a result, if you held your notes to the stated maturity date, you would not benefit from any increase in the final underlier level over 116.570% of the initial underlier level.

The following chart shows a graphical illustration of the hypothetical cash settlement amounts that we would pay on your notes on the stated maturity date, if the final underlier level were any of the hypothetical levels shown on the horizontal axis. The hypothetical cash settlement amounts in the chart are expressed as percentages of the principal amount of your notes and the hypothetical final underlier levels are expressed as percentages of the initial underlier level. The chart shows that any hypothetical final underlier level of less than 87.500% (the section left of the 87.500% marker on the horizontal axis) would result in a hypothetical cash settlement amount of less than 100.000% of the principal amount of your notes (the section below the 100.000% marker on the vertical axis) and, accordingly, in a loss of principal to the holder of the notes. The chart also shows that any hypothetical final underlier level of greater than or equal to 116.570% (the section right of the 116.570% marker on the horizontal axis) would result in a capped return on your investment.

PRS-8

Capped Leveraged Buffered S&P 500® Index-Linked Notes due July 7, 2022

The cash settlement amounts shown above are entirely hypothetical; they are based on market prices for the underlier stocks that may not be achieved on the determination date and on assumptions that may prove to be erroneous. The actual market value of your notes on the stated maturity date or at any other time, including any time you may wish to sell your notes, may bear little relation to the hypothetical cash settlement amounts shown above, and these amounts should not be viewed as an indication of the financial return on an investment in the offered notes. The hypothetical cash settlement amounts on notes held to the stated maturity date in the examples above assume you purchased your notes at their principal amount and have not been adjusted to reflect the actual issue price you pay for your notes. The return on your investment (whether positive or negative) in your notes will be affected by the amount you pay for your notes. If you purchase your notes for a price other than the principal amount, the return on your investment will differ from, and may be significantly lower than, the hypothetical returns suggested by the above examples. Please read “Risk Factors— The market value of the notes will be affected by various factors that interrelate in complex ways, and their market value may be less than the principal amount” in the accompanying Underlying Supplement.

Payments on the notes are economically equivalent to the amounts that would be paid on a combination of other instruments. For example, payments on the notes are economically equivalent to a combination of an interest-bearing bond bought by the holder and one or more options entered into between the holder and us (with one or more implicit option premiums paid over time). The discussion in this paragraph does not modify or affect the terms of the notes or the U.S. federal income tax treatment of the notes, as described elsewhere in this Pricing Supplement.

expect that any market makers will participate in a secondary market for the notes, the price at which you may be able to sell your notes is likely to depend on the price, if any, at which CIBCWM and/or its affiliates are willing to buy your notes.

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 notes prior to the stated maturity date. This may affect the price you receive upon such sale. Consequently, you should be willing to hold the notes to the stated maturity date.

The Historical Performance of the Underlier Should Not Be Taken as an Indication of Its Future Performance

The final level of the underlier will determine the amount to be paid on the notes at maturity. The historical performance of the underlier does not necessarily give an indication of its future performance. As a result, it is impossible to predict whether the level of the underlier will rise or fall during the term of the notes. The level of the underlier will be influenced by complex and interrelated political, economic, financial and other factors.

You Have No Shareholder Rights or Rights to Receive Any Underlier Stock

Investing in the notes will not make you a holder of any of the underlier stocks. Neither you nor any other holder or owner of the notes will have any rights with respect to the underlier stocks, including any voting rights, any right to receive dividends or other distributions, any rights to make a claim against the underlier stocks or any other rights of a holder of the underlier stocks. Your notes will be paid in cash and you will have no right to receive delivery of any underlier stocks.

We May Sell an Additional Aggregate Principal Amount of the Notes at a Different Issue Price

At our sole option, we may decide to sell an additional aggregate principal amount of the notes subsequent to the trade date. The issue price of the notes in the subsequent sale may differ substantially (higher or lower) from the original issue price you paid as provided on the cover of this Pricing Supplement.

If You Purchase Your Notes at a Premium to Principal Amount, the Return on Your Investment Will Be Lower Than the Return on Notes Purchased at Principal Amount and the Impact of Certain Key Terms of the Notes Will Be Negatively Affected

The cash settlement amount will not be adjusted based on the issue price you pay for the notes. If you purchase notes at a price that differs from the principal amount of the notes, then the return on your investment in such notes held to the stated maturity date will differ from, and may be substantially less than, the return on notes purchased at principal amount. If you purchase your notes at a premium to principal amount and hold them to the stated maturity date, the return on your investment in the notes will be lower than it would have been had you purchased the notes at principal amount or a discount to principal amount. In addition, the impact of the buffer level and the cap level on the return on your investment will depend upon the price you pay for your notes relative to principal amount. For example, if you purchase your notes at a premium to principal amount, the cap level will only permit a lower positive return on your investment in the notes than would have been the case for notes purchased at principal amount or a discount to principal amount. Similarly, the buffer level, while still providing some protection for the return on the notes, will allow a greater percentage decrease in your investment in the notes than would have been the case for notes purchased at principal amount or a discount to principal amount.

from values determined by pricing models used by CIBCWM as a result of dealer discounts, mark-ups or other transaction costs. Furthermore, if the dealer from which you purchase notes is to conduct trading and hedging activities for us in connection with the notes, that dealer may profit in connection with such trading and hedging activities and such profit, if any, will be in addition to the compensation that the dealer receives for the sale of the notes to you. You should be aware that the potential to earn a profit in connection with hedging activities may create a further incentive for the dealer to sell the notes to you, in addition to the compensation they would receive for the sale of the notes.

The Bank’s Estimated Value of the Notes Is Lower Than the Original Issue Price (Price to Public) of the Notes

The Bank’s estimated value is only an estimate using several factors. The original issue price of the notes exceeds the Bank’s estimated value because costs associated with selling and structuring the notes, as well as hedging the notes, are included in the original issue price of the notes. See “The Bank’s Estimated Value of the Notes” in this Pricing Supplement.

The Bank’s Estimated Value Does Not Represent Future Values of the Notes and May Differ from Others’ Estimates

The Bank’s estimated value of the notes was determined by reference to the Bank’s internal pricing models when the terms of the notes were set. This estimated value was based on market conditions and other relevant factors existing at that time and the Bank’s 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 notes that are greater than or less than the Bank’s 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 notes 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 CIBCWM or any other person would be willing to buy notes from you in secondary market transactions. See “The Bank’s Estimated Value of the Notes” in this Pricing Supplement.

The Bank’s Estimated Value Was Not Determined by Reference to Credit Spreads for Our Conventional Fixed-Rate Debt

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. If the Bank were to have used the interest rate implied by our conventional fixed-rate credit spreads, we would expect the economic terms of the notes to be more favorable to you. Consequently, our use of an internal funding rate had an adverse effect on the terms of the notes and could have an adverse effect on any secondary market prices of the notes. See “The Bank’s Estimated Value of the Notes” in this Pricing Supplement.

We Cannot Control Actions By Any of the Unaffiliated Companies Whose Securities Are Included in the Underlier

Actions by any company whose securities are included in the underlier may have an adverse effect on the price of its security, the final underlier level and the value of the notes. These companies will not be involved in the offering of the notes and will have no obligations with respect to the notes, including any obligation to take our or your interests into consideration for any reason. These companies will not receive any of the proceeds of the offering of the notes and will not be responsible for, and will not have participated in, the determination of the timing of, prices for, or quantities of, the notes to be issued. These companies will not be involved with the administration, marketing or trading of the notes and will have no obligations with respect to the cash settlement amount to be paid to you at maturity.

We and Our Respective Affiliates Have No Affiliation with the Underlier Sponsor and Have Not Independently Verified Its Public Disclosure of Information

We and our respective affiliates are not affiliated in any way with the underlier sponsor and have no ability to control or predict its actions, including any errors in or discontinuation of disclosure regarding the methods or policies relating to the calculation of the underlier. We have derived the information about the underlier sponsor and the underlier contained herein from publicly available information, without independent verification. You, as an investor in the notes, should make your own investigation into the underlier and the underlier sponsor. The underlier sponsor is not involved in the offering of the notes made hereby in any way and has no obligation to consider your interest as an owner of notes in taking any actions that might affect the value of the notes.

forward contracts” and similar instruments. See “Certain U.S. Federal Income Tax Consequences” in the accompanying Underlying Supplement. 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 notes, 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 notes should review carefully the section of the accompanying Underlying Supplement entitled “Certain U.S. Federal Income Tax Consequences” and consult their tax advisers regarding the U.S. federal tax consequences of an investment in the notes (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 Notes 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 notes, please read the section of this Pricing Supplement entitled “Certain Canadian Federal Income Tax Considerations” 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.

THE UNDERLIER

The S&P 500® Index

The underlier consists of stocks of 500 companies selected to provide a performance benchmark for the U.S. equity markets. For additional information about the underlier, see the information set forth under “Index Descriptions—The S&P U.S. Indices” beginning on page S-43 of the accompanying underlying supplement.

In addition, information about the underlier may be obtained from other sources, including, but not limited to, the underlier sponsor’s website (including information regarding the underlier’s sector weightings). We are not incorporating by reference into this pricing supplement the website or any material it includes. Neither we nor any of our affiliates makes any representation that such publicly available information regarding the underlier is accurate or complete.

Historical Closing Levels of the Underlier

The closing level of the underlier has fluctuated in the past and may, in the future, experience significant fluctuations. Any historical upward or downward trend in the closing level of the underlier during the period shown below is not an indication that the underlier is more or less likely to increase or decrease at any time during the life of your notes.

You should not take the historical levels of the underlier as an indication of the future performance of the underlier. We cannot give you any assurance that the future performance of the underlier or the underlier stocks will result in your receiving an amount greater than the outstanding principal amount of your notes on the stated maturity date.

Neither we nor any of our affiliates make any representation to you as to the performance of the underlier. Before investing in the offered notes, you should consult publicly available information to determine the levels of the underlier between the date of this Pricing Supplement and the date of your purchase of the offered notes. The actual performance of the underlier over the life of the offered notes, as well as the cash settlement amount at maturity, may bear little relation to the historical closing levels shown below.

The graph below shows the daily historical closing levels of the underlier from October 15, 2010 through October 15, 2020. On October 15, 2020, the closing level of the underlier was 3,483.34.

THE BANK’S ESTIMATED VALUE OF THE NOTES

The Bank’s estimated value of the notes 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 notes, valued using our internal funding rate for structured debt described below, and (2) the derivative or derivatives underlying the economic terms of the notes. The Bank’s estimated value does not represent a minimum price at which CIBCWM or any other person would be willing to buy your notes 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 notes as well as the higher issuance, operational and ongoing liability management costs of the notes in comparison to those costs for our conventional fixed-rate debt. For additional information, see “Additional Risk Factors Specific to Your Notes — The Bank’s Estimated Value 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 notes 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 notes was determined when the terms of the notes were set based on market conditions and other relevant factors and assumptions existing at that time. See “Additional Risk Factors Specific to Your Notes — The Bank’s Estimated Value Does Not Represent Future Values of the Notes and May Differ from Others’ Estimates” in this Pricing Supplement.

The Bank’s estimated value of the notes is lower than the original issue price of the notes because costs associated with selling, structuring and hedging the notes are included in the original issue price of the notes. These costs include 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 notes and the estimated cost of hedging our obligations under the notes. 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 notes. See “Additional Risk Factors Specific to Your Notes — The Bank’s Estimated Value of the Notes Is Lower Than the Original Issue Price (Price to Public) of the Notes” in this Pricing Supplement.

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following discussion is a brief summary of the material U.S. federal income tax considerations relating to an investment in the notes. The following summary is not complete and is both qualified and supplemented by the discussion entitled “Certain U.S. Federal Income Tax Consequences” in the accompanying Underlying Supplement, which you should carefully review prior to investing in the notes.

The U.S. federal income tax considerations of your investment in the notes are uncertain. No statutory, judicial or administrative authority directly discusses how the notes 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 notes as prepaid cash-settled derivative contracts. Pursuant to the terms of the notes, you agree to treat the notes 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 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 notes. Such gain or loss should generally be treated as long-term capital gain or loss if you have held your notes for more than one year.

The expected characterization of the notes is not binding on the IRS or the courts. It is possible that the IRS would seek to characterize the notes 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 notes 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 the notes and certain other considerations with respect to an investment in the notes, you should consider the discussion set forth in “Certain U.S. Federal Income Tax Consequences” of the accompanying Underlying Supplement. We are not responsible for any adverse consequences that you may experience as a result of any alternative characterization of the notes for U.S. federal income tax or other tax purposes.

We will not attempt to ascertain whether any of the entities whose stock is included in the underlier would be treated as a passive foreign investment company (“PFIC”) or United States real property holding corporation (“USRPHC”), both as defined for U.S. federal income tax purposes. If one or more of the entities whose stock is included in the underlier were so treated, certain adverse U.S. federal income tax consequences might apply. You should refer to information filed with the SEC and other authorities by the entities whose stock is included in the underlier and consult your tax advisor regarding the possible consequences to you if one or more of the entities whose stock is included in the underlier is or becomes a PFIC or a USRPHC.

A “dividend equivalent” payment is treated as a dividend from sources within the United States and such payments generally would be subject to a 30% U.S. withholding tax if paid to a non-U.S. holder. Under U.S. Treasury Department regulations, payments (including deemed payments) with respect to equity-linked instruments (“ELIs”) that are “specified ELIs” may be treated as dividend equivalents if such specified ELIs reference an interest in an “underlying security,” which is generally any interest in an entity taxable as a corporation for U.S. federal income tax purposes if a payment with respect to such interest could give rise to a U.S. source dividend. However, IRS guidance 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, 2023. Based on our determination that the notes are not “delta-one” instruments, non-U.S. holders should not be subject to withholding on dividend equivalent payments, if any, under the notes. However, it is possible that the notes could be treated as deemed reissued for U.S. federal income tax purposes upon the occurrence of certain events affecting the underlier or the notes, and following such occurrence the notes could be treated as subject to withholding on dividend equivalent payments. Non-U.S. holders that enter, or have entered, into other transactions in respect of the underlier or the notes should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the notes and their other transactions. If any payments are treated as dividend equivalents subject to withholding, we (or the applicable paying agent) would be entitled to withhold taxes without being required to pay any additional amounts with respect to amounts so withheld.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

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) (the “Canadian Tax Act”) generally applicable at the date hereof to a purchaser who acquires beneficial ownership of a note pursuant to this Pricing Supplement and who for the purposes of the Canadian Tax Act and the regulations thereto 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 note; (c) does not use or hold and is not deemed to use or hold the note 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 note; and (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 (a “Non-Resident Holder”). A “specified shareholder” for these purposes generally includes a person who (either alone or together with persons with whom that person is not dealing at arm’s length for the purposes of the Canadian Tax Act) owns or has the right to acquire or control or is otherwise deemed to own 25% or more of CIBC’s shares determined on a votes or fair market value basis. Special rules which apply to non-resident insurers carrying on business in Canada and elsewhere are not discussed in this summary.

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 notes 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 notes, interest payable on the notes 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 note as, on account of or in lieu of payment of, or in satisfaction of, interest.

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