Canadian Imperial Bank of Commerce

Senior Global Medium-Term Notes

$         Fixed to Floating Rate Notes Linked to the Compounded SOFR due August 16, 2028

We, Canadian Imperial Bank of Commerce (the “Bank” or “CIBC”), are offering $           aggregate principal amount of Fixed to Floating Rate Notes Linked to the Compounded SOFR (“Compounded SOFR” or the “Reference Rate”) due August 16, 2028 (CUSIP 13607XM87 / ISIN US13607XM871) (the “Notes”).

At maturity, you will receive a cash payment equal to 100% of the principal amount, plus any accrued and unpaid interest. Interest will be paid quarterly on February 16, May 16, August 16 and November 16 of each year, commencing on November 16, 2023 and ending on the Maturity Date. The Notes will accrue interest during the following periods of their term at the following rates per annum:

· From and including the Original Issue Date to but excluding February 16, 2024: 6.00%;

· From and including February 16, 2024 to but excluding the Maturity Date: the sum of Compounded SOFR and 1.25%, subject to a Minimum Rate of 0.00%.

The Notes will be issued in minimum denominations of $1,000, and integral multiples of $1,000 in excess thereof.

The Notes will not be listed on any securities exchange.

The Notes are unsecured obligations of CIBC and all payments on the Notes are subject to the credit risk of CIBC. 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 accompanying prospectus).

Neither the Securities and Exchange Commission (the “SEC”) nor any state or provincial securities commission has approved or disapproved of these Notes or determined if this pricing supplement or the accompanying prospectus supplement and prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

Investing in the Notes involves risks not associated with an investment in ordinary debt securities. See the “Additional Risk Factors” beginning on page PS-6 of this pricing supplement and the “Risk Factors” beginning on page S-1 of the accompanying prospectus supplement and page 1 of the prospectus.

	Price to Public (Original Issue Price)(1)	Underwriting Discount (1)(2)	Proceeds to Issuer
Per Note	$1,000.00	Up to $14.00	At least $986.00
Total	$	$	$

(1) Because certain dealers who purchase the Notes for sale to certain fee-based advisory accounts may forgo some or all of their commissions or selling concessions, the price to public for investors purchasing the Notes in these accounts may be between $986.00 and $1,000.00 per Note.

(2) CIBC World Markets Corp. (“CIBCWM”), acting as agent for the Bank, will receive a commission of up to $14.00 (1.40%) per $1,000 principal amount of the Notes. CIBCWM may use a portion or all of its commission to allow selling concessions to other dealers in connection with the distribution of the Notes. The other dealers may forgo, in their sole discretion, some or all of their selling concessions. See “Supplemental Plan of Distribution (Conflicts of Interest)” on page PS-13 of this pricing supplement.

We will deliver the Notes in book-entry form through the facilities of The Depository Trust Company (“DTC”) on or about August 16, 2023 against payment in immediately available funds.

Withholding:	The Bank or the applicable paying agent will deduct or withhold from a payment on a Note any present or future tax, duty, assessment or other governmental charge that the Bank determines is required by law or the interpretation or administration thereof to be deducted or withheld. Payments on a Note will not be increased by any amount to offset such deduction or withholding.
The Trade Date and the other dates set forth above are subject to change, and will be set forth in the final pricing supplement relating to the Notes.

ADDITIONAL RISK FACTORS

An investment in the Notes involves significant risks. In addition to the following risks included in this pricing supplement, we urge you to read “Risk Factors” beginning on page S-1 of the accompanying prospectus supplement and page 1 of the accompanying prospectus.

You should understand the risks of investing in the Notes and should reach an investment decision only after careful consideration, with your advisers, of the suitability of the Notes in light of your particular financial circumstances and the information set forth in this pricing supplement and the accompanying prospectus and prospectus supplement.

Structure Risks

The Interest Rate for Each Interest Period During the Floating Rate Payment Period Is Variable and May Be As Low As the Minimum Rate.

You will receive interest on the applicable Interest Payment Date during the Floating Rate Payment Period at the Interest Rate calculated on the corresponding Interest Determination Date, which may be as low as the Minimum Rate. The Interest Rate applicable to each Interest Payment Date during the Floating Rate Payment Period will fluctuate because it is equal to the sum of Compounded SOFR calculated on the applicable Interest Determination Date and 1.25%, subject to the Minimum Rate. If Compounded SOFR calculated on any Interest Determination Date were less than -1.25%, the Interest Rate for the relevant Interest Period would be equal to the Minimum Rate. Compounded SOFR, on which the Interest Rate for each Interest Period during the Floating Rate Payment Period is based, will vary and may be less than -1.25% for most or all of the Interest Determination Dates, and you may receive interest at the Minimum Rate on most or all of the Interest Payment Dates during the Floating Rate Payment Period. The return on the Notes may be lower than the return on conventional debt securities of comparable maturity.

You Will Not Know the Interest Rate for Each Interest Period During the Floating Rate Payment Period Until the End of That Interest Period.

The Reference Rate is compounded in arrears. Unlike forward-looking term rates, the Interest Rate for each Interest Period during the Floating Rate Payment Period will be calculated at the end of that Interest Period.

The Repayment of the Principal Amount Applies Only at Maturity.

The Notes offer repayment of the principal amount only if you hold your Notes until the Maturity Date. If you sell the Notes prior to maturity, you may lose some of the principal amount.

The Notes Are Riskier than Notes with a Shorter Term.

The Notes are relatively long-dated. Therefore, many of the risks of the Notes are heightened as compared to notes 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 note is typically less than the value of an otherwise comparable note with a shorter term.

Reference Rate Risks

The Occurrence of a Benchmark Transition Event Could Adversely Affect the Return (if any) on the Notes.

A Benchmark Transition Event (as defined in “Description of the Notes We May Offer – Interest Rates – Floating Rate Notes – SOFR Notes – Effect of a Benchmark Transition Event for Compounded SOFR Notes” in the accompanying prospectus supplement) could occur during the term of the Notes. Any resulting alternative replacement and Calculation Agent adjustments and determinations, as described in “Description of the Notes We May Offer – Interest Rates – Floating Rate Notes – SOFR Notes – Effect of a Benchmark Transition Event for Compounded SOFR Notes” in the accompanying prospectus supplement, could adversely affect the value of and the return on your Notes.

The Secured Overnight Financing Rate (“SOFR”) Is a Relatively New Market Index and as the Related Market Continues to Develop, There May Be an Adverse Effect on the Return on or Value of the Notes; SOFR May Be Modified or Discontinued.

The Federal Reserve Bank of New York notes on its publication page for SOFR that use of SOFR is subject to important limitations, indemnification obligations and disclaimers, including that the Federal Reserve Bank of New York may alter the methods of calculation, publication schedule, rate revision practices or availability of SOFR at any time without notice. There can be no guarantee that SOFR will not be discontinued or fundamentally altered in a

PS-6

manner that is materially adverse to the interests of investors in the Notes. If the manner in which SOFR is calculated is changed or if SOFR is discontinued, that change, or discontinuance may result in a reduction of the interest or other applicable payments payable on the Notes and a reduction in the trading price of the Notes.

SOFR Has a Very Limited History, and the Future Performance of SOFR Cannot Be Predicted Based on Historical Performance.

The publication of SOFR began in April 2018, and, therefore, it has a very limited history. In addition, the future performance of SOFR cannot be predicted based on the limited historical performance. Prior observed patterns, if any, in the behavior of market variables and their relation to SOFR, such as correlations, may change in the future. While some pre-publication historical data have been released by the Federal Reserve Bank of New York, such analysis inherently involves assumptions, estimates and approximations. The future performance of SOFR is impossible to predict and therefore no future performance of SOFR may be inferred from any of the historical actual or historical indicative data. Hypothetical or historical performance data are not indicative of, and have no bearing on, the potential performance of SOFR. You should not rely on any historical changes or trends in SOFR as an indicator of the future performance of SOFR. Since the initial publication of SOFR, daily changes in the rate have, on occasion, been more volatile than daily changes in comparable benchmark or market rates.

SOFR May Be More Volatile Than Other Benchmark or Market Rates.

Since the initial publication of SOFR, daily changes in the rate have, on occasion, been more volatile than daily changes in other benchmark or market rates, such as the U.S. dollar LIBOR Rate, during corresponding periods, and SOFR may bear little or no relation to the historical actual or historical indicative data.

Any Failure of SOFR to Gain Market Acceptance Could Adversely Affect the Notes.

SOFR was developed for use in certain U.S. dollar derivatives and other financial contracts as an alternative to U.S. dollar LIBOR in part because it is considered a good representation of general funding conditions in the overnight U.S. Treasury Repo market. However, as a rate based on transactions secured by U.S. Treasury securities, it does not measure bank-specific credit risk and, as a result, is less likely to correlate with the unsecured short-term funding costs of banks. This may mean that market participants would not consider SOFR a suitable replacement or successor for all of the purposes for which U.S. dollar LIBOR historically has been used (including, without limitation, as a representation of the unsecured short-term funding costs of banks), which may, in turn, lessen market acceptance of SOFR. Any failure of SOFR to gain market acceptance could adversely affect the return on and value of the Notes and the price at which investors can sell the Notes in the secondary market.

The Secondary Trading Market for Securities Linked to SOFR May Be Limited.

Since SOFR is a relatively new market index, SOFR-linked securities likely will have no established trading market when issued or otherwise, and an established trading market may never develop or may not be very liquid. If SOFR does not prove to be widely used as a benchmark in securities that are similar or comparable to the Notes, the trading price of the Notes may be lower than those of securities that are linked to rates that are more widely used. Similarly, market terms for securities that are linked to SOFR, including, but not limited to, the spread over the reference rate reflected in the benchmark transition provisions, may evolve over time, and as a result, trading prices of the Notes may be lower than those of later-issued securities that are based on SOFR. Investors in the Notes may not be able to sell the Notes at all or may not be able to sell the Notes at prices that will provide them with a yield comparable to similar investments that have a developed secondary market, and may consequently suffer from increased pricing volatility and market risk.

Historical Levels of SOFR Do Not Guarantee Future Levels.

The historical levels of SOFR do not guarantee its future levels. It is not possible to predict whether SOFR will rise or fall during the Floating Rate Payment Period.

Conflicts of Interest

Certain Business, Trading and Hedging Activities of Us, CIBCWM and Our Other Affiliates May Create Conflicts with Your Interests and Could Potentially Adversely Affect the Value of the Notes.

We, CIBCWM or one or more of our other affiliates may engage in trading and other business activities that are not for your account or on your behalf (such as holding or selling of the Notes for our proprietary account or effecting secondary market transactions in the Notes for other customers). These activities may present a conflict of interest between your interest in the Notes and the interests we, CIBCWM or one or more of our other affiliates may have in

PS-7

our or their proprietary accounts. We, CIBCWM and our other affiliates may engage in any such activities without regard to the Notes or the effect that such activities may directly or indirectly have on the value of the Notes.

Moreover, we, CIBCWM and our other affiliates play a variety of roles in connection with the issuance of the Notes, including hedging our obligations under the Notes. We expect to hedge our obligations under the Notes through CIBCWM, one of our other affiliates and/or another unaffiliated counterparty, which may include any dealer from which you purchase the Notes. In connection with such activities, the economic interests of us, CIBCWM and our other affiliates may be adverse to your interests as an investor in the Notes. Any of these activities may adversely affect the value of the Notes. In addition, because hedging our obligations entails risk and may be influenced by market forces beyond our control, this hedging activity may result in a profit that is more or less than expected, or it may result in a loss. We, CIBCWM, one or more of our other affiliates or any unaffiliated counterparty will retain any profits realized in hedging our obligations under the Notes even if investors do not receive a favorable investment return under the terms of the Notes or in any secondary market transaction. Any profit in connection with such hedging activities will be in addition to any other compensation that we, CIBCWM, our other affiliates or any unaffiliated counterparty receive for the sale of the Notes, which creates an additional incentive to sell the Notes to you. We, CIBCWM, our other affiliates or any unaffiliated counterparty will have no obligation to take, refrain from taking or cease taking any action with respect to these transactions based on the potential effect on an investor in the Notes.

There Are Potential Conflicts of Interest Between You and the Calculation Agent.

The Calculation Agent will, among other things, determine the Interest Rate and decide the amount of your payment for any Interest Payment Date on the Notes. The Calculation Agent will exercise its judgment when performing its functions. Because determinations made by the Calculation Agent may affect payments on the Notes, the Calculation Agent may have a conflict of interest if it needs to make any such determination.

In addition, and without limiting the generality of the previous paragraph, the Calculation Agent may make certain determinations if a “Benchmark Transition Event” (as discussed under “Additional Terms of the Notes” below) occurs or it may administer a successor rate in certain circumstances as also described herein. For the avoidance of doubt, any decision made by the Calculation Agent will be effective without consent from the holders of the Notes or any other party. Potential conflicts of interest may exist between the Bank, the Calculation Agent and holders of the Notes. All determinations made by the Calculation Agent in such a circumstance will be conclusive for all purposes and binding on the Bank and holders of the Notes. In making these potentially subjective determinations, the Bank and/or the Calculation Agent may have economic interests that are adverse to your interests, and such determinations may adversely affect the value of and return on your Notes. Because the continuation of SOFR on the current basis cannot and will not be guaranteed, the Calculation Agent is likely to exercise more discretion in respect of calculating interest payable on the Notes than would be the case in the absence of such a need to select a successor rate.

Tax Risks

The Tax Treatment of the Notes Is Uncertain.

Significant aspects of the tax treatment of the Notes are uncertain. You should consult your tax advisor about your own tax situation. See “U.S. Federal Income Tax Considerations” and “Certain Canadian Income Tax Considerations” in this pricing supplement.

General Risks

Payments on the Notes Are Subject to Our Credit Risk, and Actual or Perceived Changes in Our Creditworthiness Are Expected to Affect the Value of the Notes.

The Notes are our senior unsecured debt obligations and are not, either directly or indirectly, an obligation of any third party. As further described in the accompanying prospectus and prospectus supplement, the Notes will rank on par with all of our other unsecured and unsubordinated debt obligations, except such obligations as may be preferred by operation of law. All payments to be made on the Notes, including the interest payments and the return of the principal amount at maturity, depend on our ability to satisfy our obligations as they come due. As a result, the actual and perceived creditworthiness of us may affect the market value of the Notes and, in the event we were to default on our obligations, you may not receive the amounts owed to you under the terms of the Notes. If we default on our obligations under the Notes, your investment would be at risk and you could lose some or all of your investment. See “Description of Senior Debt Securities—Events of Default” in the accompanying prospectus.

PS-8

The Inclusion of Dealer Spread and Projected Profit from Hedging in the Original Issue Price Is Likely to Adversely Affect Secondary Market Prices.

Assuming no change in market conditions or any other relevant factors, the price, if any, at which CIBCWM or any other party is willing to purchase the Notes at any time in secondary market transactions will likely be significantly lower than the original issue price, since secondary market prices are likely to exclude underwriting commissions paid with respect to the Notes and the cost of hedging our obligations under the Notes that are included in the original issue price. The cost of hedging includes the projected profit that we and/or our affiliates may realize in consideration for assuming the risks inherent in managing the hedging transactions. These secondary market prices are also likely to be reduced by the costs of unwinding the related hedging transactions. In addition, any secondary market prices may differ from values determined by pricing models used by CIBCWM as a result of dealer discounts, mark-ups or other transaction costs.

The Notes Will Not Be Listed on Any Securities Exchange and We Do Not Expect a Trading Market for the Notes to Develop.

The Notes will not be listed on any securities exchange. Although CIBCWM and/or its affiliates may purchase the Notes from holders, they are not obligated to do so and are not required to make a market for the Notes. There can be no assurance that a secondary market will develop for the Notes. Because we do not 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 maturity. This may affect the price you receive upon such sale. Consequently, you should be willing to hold the Notes to maturity.

U.S. 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 (although to the extent inconsistent supersedes) the discussion entitled “Material Income Tax Consequences—United States Taxation” in the accompanying prospectus, which you should carefully review prior to investing in the Notes. It applies only to those U.S. Holders who are not excluded from the discussion of United States Taxation in the accompanying prospectus.

You should consult your tax advisor concerning the U.S. federal income tax and other tax consequences of your investment in the Notes 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 Mayer Brown LLP, the Notes should be treated as debt instruments for U.S. federal income tax purposes. Assuming such treatment is respected, the coupon on a Note will be taxable to a U.S. Holder as ordinary interest income at the time it accrues or is received in accordance with the U.S. Holder’s normal method of accounting for tax purposes.

Upon the sale, exchange, retirement or other disposition of a Note, a U.S. Holder will recognize taxable gain or loss equal to the difference, if any, between the amount realized on the sale, exchange, retirement or other disposition, other than accrued but unpaid interest which will be taxable as interest, and such U.S. Holder’s adjusted tax basis in the Note. A U.S. Holder’s adjusted tax basis in a Note generally will equal the cost of the Note to such U.S. Holder, and any such gain or loss will generally be capital gain or loss. For a non-corporate U.S. Holder, under current law, the maximum marginal U.S. federal income tax rate applicable to the gain will be generally lower than the maximum marginal U.S. federal income tax rate applicable to ordinary income if the U.S. Holder’s holding period for the Notes exceeds one year (i.e., such gain is long-term capital gain). Any gain or loss realized on the sale, exchange, retirement or other disposition of a Note generally will be treated as U.S. source gain or loss, as the case may be. Consequently, a U.S. Holder may not be able to claim a credit for any non-U.S. tax imposed upon a disposition of a Note. The deductibility of capital losses is subject to limitations.

PS-11

CERTAIN CANADIAN 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) and the regulations thereto (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 at all relevant times: (a) is neither resident nor deemed to be resident in Canada; (b) deals at arm’s length with the Issuer 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; (e) is not a, and deals at arm’s length with any, “specified shareholder” of the Issuer for purposes of the thin capitalization rules in the Canadian Tax Act; and (f) is not an entity in respect of which the Issuer is a “specified entity” for purposes of the Hybrid Mismatch Proposals, as defined below (a “Non-Resident Holder”). For these purposes, a “specified shareholder” 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 the Issuer’s shares determined on a votes or fair market value basis, and an entity in respect of which the Issuer is a “specified entity” generally includes (i) an entity that is a specified shareholder of the Issuer (as defined above), (ii) an entity in which the Issuer (either alone or together with entities with whom the Issuer is not dealing at arm’s length for purposes of the Canadian Tax Act) owns or has the right to acquire or control or is otherwise deemed to own a 25% or greater equity interest, and (iii) an entity in which an entity described in (i) (either alone or together with entities with whom such entity is not dealing at arm’s length for purposes of the Canadian Tax Act) owns or has the right to acquire or control or is otherwise deemed to own a 25% or greater equity interest. Special rules which apply to non-resident insurers carrying on business in Canada and elsewhere are not discussed in this summary.

For greater certainty, this summary takes into account all specific proposals to amend the Canadian Tax Act publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof, including the proposals released on April 29, 2022 with respect to “hybrid mismatch arrangements” (the “Hybrid Mismatch Proposals”). 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 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 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 the Issuer 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 advisors regarding the consequences to them of a disposition of Notes to a person with whom they are not dealing at arm’s length for purposes of the Canadian Tax Act.

SUPPLEMENTAL PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

CIBCWM will purchase the Notes from CIBC at the price to public less the underwriting discount set forth on the cover page of this pricing supplement for distribution to other registered broker-dealers, or will offer the Notes directly to investors. CIBCWM or other registered broker-dealers will offer the Notes at the price to public set forth on the cover page of this pricing supplement. CIBCWM may receive a commission of up to $14.00 (1.40%) per $1,000 principal amount of the Notes and may use a portion or all of that commission to allow selling concessions to other dealers in connection with the distribution of the Notes. The other dealers may forgo, in their sole discretion, some or all of their selling concessions. The price to public for Notes purchased by certain fee-based advisory accounts may vary between 98.60% and 100.00% of the principal amount of the Notes. Any sale of a Note to a fee-based advisory account at a price to public below 100.00% of the principal amount will reduce the agent’s commission specified on the cover page of this pricing supplement with respect to such Note. The price to public paid by any fee-based advisory account will be reduced by the amount of any fees assessed by the dealers involved in the sale of the Notes to such advisory account but not by more than 1.40% of the principal amount of the Notes.

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 may use this pricing supplement in the initial sale of the Notes. In addition, CIBCWM or any of our other affiliates may use this pricing supplement in market-making transactions in any Notes 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 Notes, 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 Notes 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 Notes. These costs and profits will likely reduce the secondary market price, if any secondary market develops, for the Notes. As a result, you may experience an immediate and substantial decline in the market value of your Notes on the Original Issue Date.
