SEC Form FWP filed by Canadian Imperial Bank of Commerce

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” and “Additional Risk Factors” beginning on page TS-7 of this term sheet and “Risk Factors” beginning on page PS-6 of product supplement EQUITY ARN-1.

The initial estimated value of the notes as of the pricing date is expected to be between $9.056 and $9.401 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-13 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.

_________________________

(1)For any purchase of 300,000 units or more in a single transaction by an individual investor or in combined transactions with the investor’s household in this offering, the public offering price and the underwriting discount will be $9.950 per unit and $0.125 per unit, respectively.

The notes:

BofA Securities

June  , 2026

Summary

The Accelerated Return Notes^® Linked to the VanEck^® Semiconductor ETF, due August  , 2027 (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. Any payments due on the notes, including any repayment of principal, will be subject to the credit risk of CIBC. The notes provide you a leveraged return, subject to a cap, if the Ending Value of the Market Measure, which is the VanEck^® Semiconductor ETF (the “Underlying Fund”), is greater than the Starting Value. If the Ending Value is equal to the Starting Value, you will receive the principal amount of your notes. If the Ending Value is less than the Starting Value, you will lose all or a portion of the principal amount of your notes. Any payments on the notes will be calculated based on the $10 principal amount per unit and will depend on the performance of the Underlying Fund, subject to our credit risk. See “Terms of the Notes” below.

The economic terms of the notes (including the Capped Value) 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-13.

The terms and risks of the notes are contained in this term sheet and in the following:

Investor Considerations

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

Hypothetical Payout Profile and Examples of Payments at Maturity

The graph below is based on hypothetical numbers and values.

The following table and examples are for purposes of illustration only.  They are based on hypothetical values and show hypothetical returns on the notes. They illustrate the calculation of the Redemption Amount and total rate of return based on a hypothetical Starting Value of 100, the Participation Rate of 300%, a hypothetical Capped Value of $13.75 per unit and a range of hypothetical Ending Values. The actual amount you receive and the resulting total rate of return will depend on the actual Starting Value, Ending Value and Capped Value, and whether you hold the notes to maturity. The following examples do not take into account any tax consequences from investing in the notes.

For recent actual prices of the Underlying Fund, see “The Underlying Fund” section below. In addition, all payments on the notes are subject to issuer credit risk.

(1)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 for the Underlying Fund.

(2)The Redemption Amount per unit cannot exceed the hypothetical Capped Value.

Redemption Amount Calculation Examples

Risk Factors

There are important differences between the notes and a conventional debt security.  An investment in the notes involves significant risks, including those listed below. You should carefully review the more detailed explanation of risks relating to the notes in the “Risk Factors” sections beginning on page PS-6 of product supplement EQUITY ARN-1, page S-1 of the prospectus supplement, and page 1 of the prospectus identified above. We also urge you to consult your investment, legal, tax, accounting, and other advisors before you invest in the notes.

Structure-related Risks

■Depending on the performance of the Underlying Fund as measured shortly before the maturity date, you may lose up to 100% of the principal amount.

■Your investment return is limited to the return represented by the Capped Value and may be less than a comparable investment directly in the Underlying Fund or the securities held by the Underlying Fund.

■Your return on the notes may be less than the yield you could earn by owning a conventional fixed or floating rate debt security of comparable maturity.

■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. If we become insolvent or are unable to pay our obligations, you may lose your entire investment.

Valuation- and Market-related Risks

■Our initial estimated value of the notes will be lower than the public offering price of the notes. The public offering price of the notes will exceed our initial estimated value because costs associated with selling and structuring the notes, as well as hedging the notes, all as further described in “Structuring the Notes” on page TS-13, are included in the public offering price of the notes.

■Our initial estimated value does not represent future values of the notes and may differ from others’ estimates. Our initial estimated value is only an estimate, which will be determined by reference to our internal pricing models when the terms of the notes are set. This estimated value will be based on market conditions and other relevant factors existing at that time, our internal funding rate on the pricing date and our assumptions about market parameters, which can include volatility, dividend rates, interest rates and other factors. Different pricing models and assumptions could provide valuations for the notes that are greater or less than our initial 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 market value of the notes could change significantly based on, among other things, changes in market conditions, including the price of the Underlying Fund, our creditworthiness, interest rate movements and other relevant factors, which may impact the price at which MLPF&S, BofAS or any other party would be willing to buy notes from you in any secondary market transactions. Our estimated value does not represent a minimum price at which MLPF&S, BofAS or any other party would be willing to buy your notes in any secondary market (if any exists) at any time.

■Our initial estimated value of the notes will not be determined by reference to credit spreads for our conventional fixed-rate debt. The internal funding rate to be used in the determination of our initial estimated value of the notes 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. If we were to use the interest rate implied by our conventional fixed-rate debt, we would expect the economic terms of the notes to be more favorable to you. Consequently, our use of an internal funding rate for market-linked notes would have an adverse effect on the economic terms of the notes, the initial estimated value of the notes on the pricing date, and any secondary market prices of the notes.

■A trading market is not expected to develop for the notes. None of us, MLPF&S or BofAS is obligated to make a market for, or to repurchase, the notes. There is no assurance that any party will be willing to purchase your notes at any price in any secondary market.

Conflict-related Risks

■Our business, hedging and trading activities, and those of MLPF&S, BofAS and our respective affiliates (including trades in shares of the Underlying Fund or the securities held by the Underlying Fund), and any hedging and trading activities we, MLPF&S, BofAS or our respective affiliates engage in for our clients’ accounts, may affect the market value and return of the notes and may create conflicts of interest with you.

■There may be potential conflicts of interest involving the calculation agent, which is BofAS.  We have the right to appoint and remove the calculation agent.

Market Measure-related Risks

■The sponsor and the investment advisor of the Underlying Fund may adjust the Underlying Fund in a way that could adversely affect the price of the Underlying Fund and consequently, the return on the notes, and have no obligation to consider your interests.

■The sponsor of the MVIS^® US Listed Semiconductor 25 Index (the “Underlying Index”) may adjust the Underlying Index in a way that affects its level, and has no obligation to consider your interests.

■As a noteholder, you will have no rights of a holder of shares of the Underlying Fund or the securities held by the Underlying Fund, and you will not be entitled to receive securities, dividends or other distributions by the issuers of those securities.

■While we, MLPF&S, BofAS or our respective affiliates may from time to time own securities of companies included in the Underlying Fund, we, MLPF&S, BofAS and our respective affiliates do not control any company included in the Underlying Fund, and have not verified any disclosure made by any other company.

■There are liquidity and management risks associated with the Underlying Fund.

■The performance of the Underlying Fund may not correlate with the performance of its Underlying Index as well as the net asset value per share of the Underlying Fund, especially during periods of market volatility when the liquidity and the market price of shares of the Underlying Fund and/or the securities held by the Underlying Fund may be adversely affected, sometimes materially.

■The payments on the notes will not be adjusted for all corporate events that could affect the Underlying Fund. See “Description of ARNs—Anti-Dilution and Discontinuance Adjustments Relating to Underlying Funds” beginning on page PS-26 of product supplement EQUITY ARN-1.

Tax-related Risks

■The U.S. federal income tax consequences of the notes are uncertain, and may be adverse to a holder of the notes.  See “Summary of U.S. Federal Income Tax Consequences” below and “U.S. Federal Income Tax Summary” beginning on page PS-38 of product supplement EQUITY ARN-1. For a discussion of the Canadian federal income tax consequences of investing in the notes, see “Material Income Tax Consequences—Canadian Taxation” in the prospectus, as supplemented by the discussion under “Summary of Canadian Federal Income Tax Considerations” herein.

Additional Risk Factors

The securities held by the Underlying Fund are concentrated in one sector. 

All of the securities held by the Underlying Fund are issued by companies in the semiconductor production and equipment sector. As a result, the securities that will determine the price of the Underlying Fund are concentrated in one sector. Although an investment in the notes will not give holders any ownership or other direct interests in the securities held by the Underlying Fund, the return on the notes will be subject to certain risks similar to those associated with direct equity investments in the semiconductor production and equipment sector. The notes may be subject to greater volatility and be more adversely affected by a single positive or negative economic, political or regulatory occurrence affecting this sector than a different investment linked to securities of a more broadly diversified group of issuers.

Adverse conditions in the semiconductor production and equipment sector may reduce your return on the notes. 

All or substantially all of the stocks held by the Underlying Fund are issued by companies whose primary line of business is directly associated with the semiconductor production and equipment sector. The Underlying Fund is subject to the risk that companies that are in the semiconductor production and equipment sector may be similarly affected by particular economic or market events. As product cycles shorten and manufacturing capacity increases, these companies may become increasingly subject to aggressive pricing, which hampers profitability. Semiconductor companies are vulnerable to wide fluctuations in securities prices due to rapid product obsolescence. Many semiconductor companies may not successfully introduce new products, develop and maintain a loyal customer base or achieve general market acceptance for their products, and failure to do so could have a material adverse effect on their business, results of operations and financial condition. Reduced demand for end-user products, underutilization of manufacturing capacity, and other factors could adversely impact the operating results of companies in the semiconductor production and equipment sector. Semiconductor companies typically face high capital costs and such companies may need additional financing, which may be difficult to obtain. They also may be subject to risks relating to research and development costs, and the availability and price of components. Moreover, they may be heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. In addition, natural disasters, acts of terrorism or war could cause disruptions in manufacturing operations of semiconductor companies.

Some of the companies involved in the semiconductor production and equipment sector are also engaged in other lines of business unrelated to the semiconductor business, and they may experience problems with these lines of business, which could adversely affect their operating results. The international operations of many semiconductor companies, and the fact that many of them are organized outside the U.S., expose them to risks associated with instability and changes in economic and political conditions, foreign currency fluctuations, changes in foreign regulations, tariffs and trade disputes, competition from subsidized foreign competitors with lower production costs and other risks inherent to international business. The semiconductor production and equipment sector is highly cyclical, which may cause the operating results of many semiconductor companies to vary significantly. Companies in the semiconductor production and equipment sector also may be subject to competition from new market entrants. The stock prices of companies in the semiconductor production and equipment sector have been and will likely continue to be extremely volatile compared to the overall market. These factors could affect the semiconductor production and equipment sector and could affect the prices of the equity securities held by the Underlying Fund and consequently, the price of the Underlying Fund during the term of the notes, which may adversely affect the return on your notes.

A limited number of equity securities held by the Underlying Fund may affect its price, and the Underlying Index is not necessarily representative of the semiconductor production and equipment sector.

The number of securities held by the Underlying Fund is limited. In addition, a few top securities held by the Underlying Fund may constitute a substantial portion of its net assets.  Any reduction in the market price of those securities is likely to have a substantial adverse impact on the price of the Underlying Fund and the return on the notes.

While the securities included in the Underlying Index are equity securities of companies generally considered to be involved in the semiconductor production and equipment sector, the securities included in the Underlying Index may not follow the price movements of the entire semiconductor production and equipment sector generally. If the securities included in the Underlying Index (and, accordingly, the securities held by the Underlying Fund) decline in value, the Underlying Fund will decline in value even if security prices in the semiconductor production and equipment sector generally increase in value.

The Underlying Fund

All disclosures contained in this term sheet regarding the Underlying Fund and the Underlying Index, including, without limitation, their make-up, method of their calculation, and changes in their components, have been derived from publicly available sources which we have not independently verified.  The information reflects the policies of, and is subject to change by, Van Eck Associates Corporation (“VanEck”). The consequences of any discontinuance of the Underlying Fund or the Underlying Index are discussed in the section entitled “Description of ARNs—Anti-Dilution and Discontinuance Adjustments Relating to Underlying Funds—Discontinuance of or Material Change to an Underlying Fund” beginning on page PS-29 of product supplement EQUITY ARN-1. None of us, the calculation agent, MLPF&S or BofAS accepts any responsibility for the calculation, maintenance, or publication of the Underlying Fund, the Underlying Index, or any successor fund or index.

The VanEck^® Semiconductor ETF

The Fund is an exchange-traded fund. The Fund seeks to replicate, before fees and expenses, the price and yield performance of the MVIS^® US Listed Semiconductor 25 Index (the “Underlying Index”), which is intended to track the overall performance of companies involved in semiconductor production and equipment. Shares of the Fund are listed and trade on The Nasdaq Stock Market LLC under the ticker symbol “SMH”.

Information provided to or filed with the SEC by the VanEck ETF Trust pursuant to the Securities Act of 1933 and the Investment Company Act of 1940 can be located by reference to SEC file numbers 333-123257 and 811-10325, respectively, through the SEC’s website at http://www.sec.gov.

Investment Objective and Strategy

The Fund normally invests at least 80% of its total assets in securities that comprise the Fund’s benchmark index. The Underlying Index includes common stocks and depositary receipts of U.S. exchange-listed companies in the semiconductor industry. Such companies may include medium-capitalization companies and foreign companies that are listed on a U.S. exchange. To be initially eligible for the Underlying Index, companies must generate at least 50% of their revenues from semiconductors. Semiconductors include companies engaged primarily in the production of semiconductors and semiconductor equipment. Of the largest 50 stocks in the semiconductor industry by full market capitalization, the top 25 by free-float market capitalization (i.e., includes only shares that are readily available for trading in the market) and three month average daily trading volume are included in the Underlying Index.

The Fund, using a “passive” or indexing investment approach, attempts to approximate the investment performance of the Underlying Index by investing in a portfolio of securities that generally replicates the Underlying Index. Unlike many investment companies that try to “beat” the performance of a benchmark index, the Fund does not try to “beat” the Underlying Index and does not seek temporary defensive positions that are inconsistent with its investment objective of seeking to replicate the Underlying Index.

The MVIS^® US Listed Semiconductor 25 Index

The MVIS^® US Listed Semiconductor 25 Index tracks the performance of the 25 largest and most liquid U.S. exchange-listed companies in the semiconductor industry. This is a modified market cap-weighted index, and only includes companies that generate at least 50% of their revenue from semiconductors or semiconductor equipment.

Index Composition and Maintenance

The Index Universe

The 4.5%/20%/50% capping scheme is applied to ensure diversification. This weighting scheme ensures diversification by assigning weights to components which cannot exceed 20% but still ensures bigger sizes of bigger companies.

1. All index components are weighted by their free-float market capitalization.

2. All companies exceeding 4.5% but at least the largest 5 and at the maximum the largest 10 companies are grouped together (so called “Large-Weights”). All other companies are grouped together as well (so called “Small-Weights”).

3. The aggregated weighting of the Large-Weights is capped at 50%:

•Large-Weights: If the aggregated weighting of all companies in Large-Weight exceeds 50%, then a capping factor is calculated to bring the weighting down to 50% - at the same time a second capping factor for the Small-Weights is calculated to increase the aggregated weight to 50%. These two factors are then applied to all companies in the Large-Weights or the Small-Weights respectively. Then

•Large-Weights: The maximum weight for any single stock is 20% and the minimum weighting is 5%. If a stock is above the maximum or below the minimum weight, then the weight will be reduced to the maximum weight or increased to the minimum weight and the excess weight shall be redistributed proportionally across all other remaining index constituents in the Large- Weights. Then

•Small-Weights: The maximum weight for any single stock is 4.5%. If a stock is above the maximum weight, then the weight will be reduced to the maximum weight and the excess weight shall be redistributed proportionally across all other remaining index constituents in the Small-Weights.

Review procedure

The components of this index are reviewed on a semi-annual basis in March and September. Target coverage is 25 companies. The reviews for the Underlying Index are based on the closing data on the last business day in February, May, August and November. If a company does not trade on the last business day in February, May, August or November, the last available price for this company will be used. A “business day” means any day (other than a Saturday or Sunday) on which commercial banks and foreign exchange markets settle payments in Frankfurt. The underlying index data (e.g. new number of shares, new free-float factors, and new weighting cap factors) is announced on the second Friday in a quarter-end month (i.e. March, June, September and December). The weighting cap factors are based on closing data of the Wednesday prior to the second Friday in a quarter-end month (i.e. March, June, September and December). GDP Factors are announced on the second Friday in June. Changes will be implemented and based on the closing prices of the third Friday of every quarter-end month (i.e. March, June, September and December). If the third Friday is not business day, the review will take place on the last business day before the third Friday. If a company does not trade on the third Friday of a quarter-end month, then the last available price for this company will be used. Changes become effective on the next business day.

The Underlying Index is reviewed based on the following procedure:

1. The largest 50 stocks (by full market capitalization) from the investable universe qualify.

2. The 50 stocks are ranked in two different ways - by free-float market capitalization in descending order (the largest company receives rank “1”) and then by three-month average-daily-trading volume in descending order (the most liquid company receives rank “1”). These two ranks are added up.

3. The 50 stocks are ranked now by their sum of the two ranks in step 2 in ascending order. If two companies have the same sum of ranks, then the larger company is placed on top.

a.     Initially, the highest ranked 25 companies made up the index.

b.    On-going, a 10-40 buffer is applied: The highest ranked 10 companies qualify. The remaining15 companies are selected from the highest ranked remaining current index components ranked between 11 and 40. If the number of selected companies is still below 25, then the highest ranked remaining stocks are selected until 25 companies were selected.

For all corporate events that result in a stock deletion from the index, the deleted stock will be replaced with the highest ranked non-component on the most recent selection list immediately only if the number of components in the index would drop below 20. The replacement stock will be added at the same weight as the deleted stock. Only in case the number of components drops below its minimum due to a merger of two or more index components, the replacement stock will be added with its free-float market capitalization, weighted with the capping factor of the uncapped components in the small-weight group of the weighting scheme. In all other cases, i.e. there is no replacement, the additional weight resulting from the deletion will be redistributed proportionally across all other index constituents.

The following graph shows the daily historical performance of the Underlying Fund on its primary exchange in the period from December 11, 2019 through June 2, 2026. 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 2, 2026, the Closing Market Price of the Underlying Fund was $632.21. 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 Fund

This historical data on the Underlying Fund is not necessarily indicative of the future performance of the Underlying Fund or what the value of the notes may be. Any historical upward or downward trend in the price per share of the Underlying Fund during any period set forth above is not an indication that the price per share of the Underlying Fund 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 Fund.

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 Fund 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:

•the investor’s spouse (including a domestic partner), siblings, parents, grandparents, spouse’s parents, children and grandchildren, but excluding accounts held by aunts, uncles, cousins, nieces, nephews or any other family relationship not directly above or below the individual investor;

•a family investment vehicle, including foundations, limited partnerships and personal holding companies, but only if the beneficial owners of the vehicle consist solely of the investor or members of the investor’s household as described above; and

•a trust where the grantors and/or beneficiaries of the trust consist solely of the investor or members of the investor’s household as described above; provided that, purchases of the notes by a trust generally cannot be aggregated together with any purchases made by a trustee’s personal account.       

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 Fund.  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.

At maturity, we are required to pay the Redemption Amount to holders of the notes, which will be calculated based on the performance of the Underlying Fund and the $10 per unit principal amount. 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 Fund , 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.

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”). On January 29, 2026, the Department of Finance (Canada) released for consultation proposed amendments to the Hybrid Mismatch Rules which, if enacted in the form proposed, would expand the categories of payments to which the Hybrid Mismatch Rules may apply.  This summary further assumes that such proposals will not result in the application of the Hybrid Mismatch Rules to amounts payable to a holder in respect of the notes, but there can be no assurances in this regard. Investors should note that the Hybrid Mismatch Rules, and the proposed amendments thereto, 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 considerations 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 EQUITY ARN-1, 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, subject to the discussion in the product supplement concerning the potential application of the “constructive ownership” rules under Section 1260 of the Code, you should generally recognize capital gain or loss upon the sale, exchange, redemption or payment on maturity in an amount equal to the difference between the amount you receive at such time and the amount that you paid for your 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.  Non-U.S. holders should consult the section entitled “U.S. Federal Income Tax Summary—Non-U.S. Holders” in product supplement EQUITY ARN-1.

The expected characterization of the notes 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. 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 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.

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.
