The notes are being issued by Canadian Imperial Bank of Commerce (“CIBC”). There are important differences between the notes and a conventional debt security, including different investment risks and certain additional costs. See “Risk Factors” beginning on page TS-6 of this term sheet and beginning on page PS-6 of product supplement STEPS-1.

The initial estimated value of the notes as of the pricing date is expected to be between $9.155 and $9.691 per unit, which is less than the public offering price listed below. See “Summary” on the following page, “Risk Factors” beginning on page TS-6 of this term sheet and “Structuring the Notes” on page TS-10 of this term sheet for additional information. The actual value of your notes at any time will reflect many factors and cannot be predicted with accuracy.

None of the Securities and Exchange Commission (the “SEC”), any state securities commission, or any other regulatory body has approved or disapproved of these securities or determined if this Note Prospectus (as defined below) is truthful or complete. Any representation to the contrary is a criminal offense.

BofA Securities

July     , 2024

Summary

The STEP Income Securities^® Linked to the Common Stock of Freeport-McMoRan Inc., due July  , 2025 (the “notes”) are our senior unsecured debt securities. The notes are not guaranteed or insured by the Canada Deposit Insurance Corporation, the U.S. Federal Deposit Insurance Corporation or any other governmental agency of the United States, Canada or any other jurisdiction or secured by collateral. The notes are not bail-inable debt securities (as defined on page 6 of the prospectus). The notes will rank equally with all of our other unsecured and unsubordinated debt. All payments due on the notes, including any repayment of principal, will be subject to the credit risk of CIBC. The notes provide quarterly interest payments. Additionally, if the Ending Value of the Market Measure, which is the common stock of Freeport-McMoRan Inc. (the “Underlying Stock”), is at or above the Step Level, the notes will also provide a payment of [$0.10 to $0.50] per unit at maturity. If the Ending Value is less than the Step Level, the Redemption Amount will not be greater than your principal amount. If the Ending Value is less than the Starting Value, the Redemption Amount will be less than the principal amount of your notes, and may be as low as zero. All payments on the notes will be calculated based on the $10 principal amount per unit and will depend on the performance of the Underlying Stock, subject to our credit risk. See “Terms of the Notes” below.

The economic terms of the notes (including the Step Payment) are based on our internal funding rate, which is the rate we would pay to borrow funds through the issuance of market-linked notes, and the economic terms of certain related hedging arrangements. Our internal funding rate is typically lower than the rate we would pay when we issue conventional fixed rate debt securities. This difference in funding rate, as well as the underwriting discount and the hedging-related charge and certain service fee described below, will reduce the economic terms of the notes to you and the initial estimated value of the notes on the pricing date. Due to these factors, the public offering price you pay to purchase the notes will be greater than the initial estimated value of the notes.

On the cover page of this term sheet, we have provided the initial estimated value range for the notes. This initial estimated value range was determined based on our pricing models. The initial estimated value as of the pricing date will be based on our internal funding rate on the pricing date, market conditions and other relevant factors existing at that time, and our assumptions about market parameters. For more information about the initial estimated value and the structuring of the notes, see “Structuring the Notes” on page TS-10.

Investor Considerations

We urge you to consult your investment, legal, tax, accounting, and other advisors before you invest in the notes.

Hypothetical Payments at Maturity

The following examples are for purposes of illustration only. They are based on hypothetical values and show hypothetical payments on the notes. The actual amount you receive and the resulting return will depend on the actual Starting Value, Threshold Value, Ending Value, Step Level, Step Payment, and term of your investment. The following examples do not take into account any tax consequences from investing in the notes. These examples are based on:

The hypothetical Starting Value of $100.00 used in these examples has been chosen for illustrative purposes only, and does not represent a likely actual Starting Value of the Underlying Stock. For recent actual prices of the Underlying Stock, see “The Underlying Stock” section below. In addition, all payments on the notes are subject to issuer credit risk.

Example 1

The Ending Value is $120.50 (120.50% of the Starting Value)

The Ending Value is greater than the Step Level. Consequently, in addition to the quarterly interest payments, you will receive on the maturity date the principal amount plus the Step Payment of $0.30 per unit. The Redemption Amount will therefore be equal to $10.30 per unit ($10.00 plus the Step Payment of $0.30 per unit).

Example 2

The Ending Value is $110.50 (110.50% of the Starting Value)

The Ending Value is greater than the Starting Value and the Threshold Value but less than the Step Level. Consequently, you will receive the quarterly interest payments, but you will not receive the Step Payment on the maturity date. The Redemption Amount will therefore be equal to the principal amount of $10.00 per unit.

Example 3

The Ending Value is $70.00 (70.00% of the Starting Value)

The Ending Value is less than the Starting Value and the Threshold Value. Consequently, you will receive the quarterly interest payments, but you will not receive the Step Payment on the maturity date, and you will participate on a 1-for-1 basis in the decrease in the price of the Underlying Stock. The Redemption Amount per unit will equal:

On the maturity date, you will receive a Redemption Amount equal to $7.00 per unit.

The Underlying Stock

We have derived the following information from publicly available documents. We have not independently verified the accuracy or completeness of the following information. Freeport-McMoRan Inc. is a copper, gold and molybdenum mining company.

Because the Underlying Stock is registered under the Securities Exchange Act of 1934, the Underlying Company is required to file periodically certain financial and other information specified by the SEC. Information provided to or filed with the SEC by the Underlying Company can be located through the SEC’s website at http://www.sec.gov by reference to SEC CIK number 831259.

This term sheet relates only to the notes and does not relate to the Underlying Stock or to any other securities of the Underlying Company. None of us, MLPF&S, BofAS or any of our respective affiliates has participated or will participate in the preparation of the Underlying Company’s publicly available documents. None of us, MLPF&S, BofAS or any of our respective affiliates has made any due diligence inquiry with respect to the Underlying Company in connection with the offering of the notes. None of us, MLPF&S, BofAS or any of our respective affiliates makes any representation that the publicly available documents or any other publicly available information regarding the Underlying Company are accurate or complete. Furthermore, there can be no assurance that all events occurring prior to the date of this term sheet, including events that would affect the accuracy or completeness of these publicly available documents that would affect the trading price of the Underlying Stock, have been or will be publicly disclosed. Subsequent disclosure of any events or the disclosure of or failure to disclose material future events concerning the Underlying Company could affect the price of the Underlying Stock and therefore could affect your return on the notes. Information from outside sources is not incorporated by reference in, and should not be considered part of, this term sheet or any accompanying prospectus, prospectus supplement or product supplement. The selection of the Underlying Stock is not a recommendation to buy or sell the Underlying Stock.

The Underlying Stock trades on the New York Stock Exchange (the “NYSE”) under the symbol “FCX.”

Historical Data

The following graph shows the daily historical performance of the Underlying Stock on its primary exchange in the period from January 1, 2014 through June 28, 2024.  We obtained this historical data from Bloomberg L.P.  We have not independently verified the accuracy or completeness of the information obtained from Bloomberg L.P. On June 28, 2024, the Closing Market Price of the Underlying Stock was $48.60. The graph below may have been adjusted to reflect certain corporate actions such as stock splits and reverse stock splits.

Historical Performance of the Underlying Stock

This historical data on the Underlying Stock is not necessarily indicative of its future performance or what the value of the notes may be. Any historical upward or downward trend in the price per share of the Underlying Stock during any period set forth above is not an indication that the price per share of the Underlying Stock is more or less likely to increase or decrease at any time over the term of the notes.

Before investing in the notes, you should consult publicly available sources for the prices and trading pattern of the Underlying Stock.

Supplement to the Plan of Distribution

Under our distribution agreement with BofAS, BofAS will purchase the notes from us as principal at the public offering price indicated on the cover of this term sheet, less the indicated underwriting discount. MLPF&S will in turn purchase the notes from BofAS for resale, and it will receive a selling concession in connection with the sale of the notes in an amount up to the full amount of the underwriting discount set forth on the cover of this term sheet.

We will pay a fee to a broker dealer in which an affiliate of BofAS has an ownership interest for providing certain services with respect to this offering, which will reduce the economic terms of the notes to you.

We may deliver the notes against payment therefor in New York, New York on a date that is greater than one business day following the pricing date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, if the initial settlement of the notes occurs more than one business day from the pricing date, purchasers who wish to trade the notes more than one business day prior to the original issue date will be required to specify alternative settlement arrangements to prevent a failed settlement.

The notes will not be listed on any securities exchange. In the original offering of the notes, the notes will be sold in minimum investment amounts of 100 units. If you place an order to purchase the notes, you are consenting to MLPF&S and/or one of its affiliates acting as a principal in effecting the transaction for your account.

MLPF&S and BofAS may repurchase and resell the notes, with repurchases and resales being made at prices related to then-prevailing market prices or at negotiated prices, and these prices will include MLPF&S’s and BofAS’s trading commissions and mark-ups or mark-downs. MLPF&S and BofAS may act as principal or agent in these market-making transactions; however, neither is obligated to engage in any such transactions. At their discretion, for a short, undetermined initial period after the issuance of the notes, MLPF&S and BofAS may offer to buy the notes in the secondary market at a price that may exceed the initial estimated value of the notes. Any price offered by MLPF&S or BofAS for the notes will be based on then-prevailing market conditions and other considerations, including the performance of the Underlying Stock and the remaining term of the notes. However, none of us, MLPF&S, BofAS or any of our respective affiliates is obligated to purchase your notes at any price or at any time, and we cannot assure you that we, MLPF&S, BofAS or any of our respective affiliates will purchase your notes at a price that equals or exceeds the initial estimated value of the notes.

The value of the notes shown on your account statement will be based on BofAS’s estimate of the value of the notes if BofAS or another of its affiliates were to make a market in the notes, which it is not obligated to do. That estimate will be based upon the price that BofAS may pay for the notes in light of then-prevailing market conditions, and other considerations, as mentioned above, and will include transaction costs. At certain times, this price may be higher than or lower than the initial estimated value of the notes.

The distribution of the Note Prospectus in connection with these offers or sales will be solely for the purpose of providing investors with the description of the terms of the notes that was made available to investors in connection with their initial offering. Secondary market investors should not, and will not be authorized to, rely on the Note Prospectus for information regarding CIBC or for any purpose other than that described in the immediately preceding sentence.

An investor’s household, as referenced on the cover of this term sheet, will generally include accounts held by any of the following, as determined by MLPF&S in its discretion and acting in good faith based upon information then available to MLPF&S:

Purchases in retirement accounts will not be considered part of the same household as an individual investor’s personal or other non-retirement account, except for individual retirement accounts (“IRAs”), simplified employee pension plans (“SEPs”), savings incentive match plan for employees (“SIMPLEs”), and single-participant or owners only accounts (i.e., retirement accounts held by self-employed individuals, business owners or partners with no employees other than their spouses).

Please contact your Merrill financial advisor if you have any questions about the application of these provisions to your specific circumstances or think you are eligible.

Structuring the Notes

The notes are our debt securities, the return on which is linked to the performance of the Underlying Stock. As is the case for all of our debt securities, including our market-linked notes, the economic terms of the notes reflect our actual or perceived creditworthiness at the time of pricing. The internal funding rate we use in pricing the market-linked notes is typically lower than the rate we would pay when we issue conventional fixed-rate debt securities of comparable maturity. This difference 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. This generally relatively lower internal funding rate, which is reflected in the economic terms of the notes, along with the fees and charges associated with market-linked notes, typically results in the initial estimated value of the notes on the pricing date being less than their public offering price.

Payments on the notes, including the interest payments on the notes and the Redemption Amount, will be calculated based on the $10 Principal Amount per unit. The Redemption Amount will depend on the performance of the Underlying Stock. We are also required to make the interest payments on the notes. In order to meet these payment obligations, at the time we issue the notes, we may choose to enter into certain hedging arrangements (which may include call options, put options or other derivatives) with BofAS or one of its affiliates. The terms of these hedging arrangements are determined by seeking bids from market participants, including BofAS and its affiliates, and take into account a number of factors, including our creditworthiness, interest rate movements, the volatility of the Underlying Stock, the tenor of the notes and the tenor of the hedging arrangements. The economic terms of the notes and their initial estimated value depend in part on the terms of these hedging arrangements.

BofAS has advised us that the hedging arrangements will include a hedging-related charge of approximately $0.05 per unit, reflecting an estimated profit to be credited to BofAS from these transactions. Since hedging entails risk and may be influenced by unpredictable market forces, additional profits and losses from these hedging arrangements may be realized by BofAS or any third party hedge providers.

Summary of 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) 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 term sheet 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 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 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 note is a “specified entity”, and is not a “specified entity” in respect of such a transferee, in each case, for purposes of the Hybrid Mismatch Rules, as defined below (a “Non-Resident Holder”). Special rules which apply to non-resident insurers carrying on business in Canada and elsewhere are not discussed in this summary.

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

This summary is supplemental to and should be read together with the description of material Canadian federal income tax considerations relevant to a Non-Resident Holder owning 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 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.

Summary of U.S. Federal Income Tax Consequences

The following discussion is a brief summary of the material U.S. federal income tax consequences relating to an investment in the notes. The following summary is not complete and is both qualified and supplemented by, or in some cases supplements, the discussion entitled “U.S. Federal Income Tax Summary” in product supplement STEPS-1, which you should carefully review prior to investing in the notes.

The U.S. federal income tax consequences 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 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 your notes are so treated, you should generally recognize capital gain or loss upon the sale, exchange, redemption or payment at maturity in an amount equal to the difference between the amount you receive at such time, including any Step Payment, and the amount that you paid for your notes. Such gain or loss should generally be long-term capital gain or loss if you have held your notes for more than one year.

If you are a U.S. Holder, although the treatment of the periodic interest payments is unclear, we intend to treat the periodic interest payments, including on the maturity date, as ordinary income includible by you at the time such payments accrue or are received in accordance with your normal method of accounting for U.S. federal income tax purposes. If you are an accrual method taxpayer who keeps an applicable financial statement, you may be required to include a periodic interest payment in income earlier than under your regular method of tax accounting if the income is recognized earlier on such applicable financial statement.

The characterization described above is not binding on the U.S. Internal Revenue Service (the “IRS”) or the courts. Thus, it is possible that the IRS would seek to characterize your notes in a manner that results in tax consequences to you that are different from those described above or in the accompanying product supplement. For a more detailed discussion of certain alternative characterizations with respect to your notes and certain other considerations with respect to your investment in the notes, you should consider the discussion set forth in “U.S. Federal Income Tax Summary” of the product 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.

With respect to the discussion in the product supplement regarding “dividend equivalent” payments, the IRS has issued a notice that provides that withholding on dividend equivalent payments will not apply to specified ELIs that are not delta-one instruments and that are issued before January 1, 2027.

You should consult your tax advisor as to the tax consequences of such characterization and any possible alternative characterizations of the notes 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 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.
