[424B2] Canadian Imperial Bank of Commerce Prospectus Supplement

Rhea-AI Filing Summary

Canadian Imperial Bank of Commerce (CIBC) is offering 475,747 units of Autocallable Strategic Accelerated Redemption Securities linked to the VanEck® Gold Miners ETF (GDX). Each note has a $10 face value, settles on 25-Jun-2025 and matures 30-Jun-2028, unless automatically called earlier.

Automatic call feature: If on any Observation Date (18-Jun-2026, 17-Jun-2027, 23-Jun-2028) the ETF closes at or above the Starting Value of 53.51, the note is redeemed for the applicable Call Amount: $12.051 (-1 yr, +20.51%), $14.102 (-2 yr, +41.02%) or $16.153 (-3 yr, +61.53%).

Downside exposure: If the note is not called and the Ending Value is below 53.51, investors incur a 1-to-1 loss on the principal with up to 100% at risk. There is no periodic coupon, dividend entitlement, or principal protection.

Pricing economics: Public offering price is $10.00 per unit; underwriting discount is $0.20 and hedging charge $0.05, leaving $9.80 in proceeds to CIBC. The initial estimated value, based on CIBC’s internal funding rate and models, is $9.667, 3.33% below the offering price.

Credit & liquidity: The notes are senior unsecured obligations of CIBC, subject to its credit risk, not FDIC- or CDIC-insured, and will not be listed on any exchange, resulting in limited secondary-market liquidity.

Positive

• Potential return of up to 61.53% in three years if GDX closes at or above the starting level on the final observation date.
• Early call feature allows accelerated redemption with premiums of 20.51% or 41.02% if performance is favorable in years one or two.

Negative

• Full downside participation: Investors lose principal 1-for-1 below the starting value, with no protection buffer.
• Initial estimated value ($9.667) is below the $10 issue price, indicating an immediate value drag of 3.33%.
• No interest or dividend income; total return depends solely on ETF price movement.
• Senior unsecured exposure to CIBC with no FDIC/CDIC insurance or collateral.
• Limited secondary-market liquidity and no exchange listing may hinder exit prior to maturity.

Insights

Financial Analyst

TL;DR: Structured note offers capped upside (≤61.53%) and full downside; value priced below par; credit and liquidity risks apply.

The product provides a defined return profile: if GDX stays flat or rises, investors may realize annualized gains of roughly 19–20% (first call) down to 16% (final call) before compounding. However, the upside is capped at 61.53% over three years, while downside is uncapped. The 3.33% gap between the $10 offer price and $9.667 estimated value reflects dealer margin and funding cost, a typical but material drag. Investors also forgo dividends from the ETF and receive no coupons, so the total return depends solely on price performance. From an equity-linked perspective, the note may appeal to investors with a moderately bullish or range-bound view on gold miners for the next 1-3 years.

Risk Analyst

TL;DR: Full principal risk, unsecured CIBC exposure, illiquidity and valuation discount heighten overall product risk.

Key risks include: (1) Credit risk—all payments rely on CIBC, with no collateral or bail-in treatment; (2) Market risk—a 1-to-1 loss below the 100% threshold offers no buffer; (3) Liquidity risk—no exchange listing and likely wide bid-ask spreads; (4) Valuation risk—$0.333 premium over the modeled value plus $0.25 combined dealer compensation reduces secondary value at issuance. The absence of periodic coupons increases negative carry for holders compared with conventional bonds. Overall, the note is best suited for sophisticated investors who can absorb full loss and who understand the timing and probability of automatic calls.

Summary

The Autocallable Strategic Accelerated Redemption Securities^® Linked to the VanEck^® Gold Miners ETF, due June 30, 2028 (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 will be automatically called at the applicable Call Amount if the Observation Level of the Market Measure, which is the VanEck^® Gold Miners ETF (the “Underlying Fund”), on any Observation Date is equal to or greater than the Starting Value. You will not receive any notice from us if the notes are automatically called. If your notes are not called, 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 Call Premiums and the Call Amounts) 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, reduced 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 is greater than the initial estimated value of the notes.

On the cover page of this term sheet, we have provided the initial estimated value for the notes. This initial estimated value was determined based on our pricing models, and was 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.

Examples of Hypothetical Payments

The following 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 Call Amount or Redemption Amount, as applicable, based on the hypothetical terms set forth below. The actual amount you receive and the resulting return will depend on the actual Starting Value, Threshold Value, Call Level, Observation Levels 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:

1)	a Starting Value of 100.00;
2)	a Threshold Value of 100.00;
3)	a Call Level of 100.00;
4)	the term of the notes from June 25, 2025 to June 30, 2028, if the notes are not called on the first two Observation Dates;
5)	a Call Premium of 20.51% of the principal amount if the notes are called on the first Observation Date; 41.02% if called on the second Observation Date; and 61.53% if called on the final Observation Date; and
6)	Observation Dates occurring on June 18, 2026, June 17, 2027 and June 23, 2028 (the final Observation Date).

The hypothetical Starting Value of 100.00 used in these examples has been chosen for illustrative purposes only. The actual Starting Value is 53.51, which was the Closing Market Price of the Underlying Fund on the pricing date. 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.

Notes Are Called on an Observation Date

The notes will be called at $10.00 plus the applicable Call Premium if the Observation Level on one of the Observation Dates is equal to or greater than the Call Level. After the notes are called, they will no longer remain outstanding and there will not be any further payments on the notes.

Example 1 - The Observation Level on the first Observation Date is 110.00. Therefore, the notes will be called at $10.00 plus the Call Premium of $2.051 = $12.051 per unit.

Example 2 - The Observation Level on the first Observation Date is below the Call Level, but the Observation Level on the second Observation Date is 150.00. Therefore, the notes will be called at $10.00 plus the Call Premium of $4.102 = $14.102 per unit.

Example 3 - The Observation Levels on the first two Observation Dates are below the Call Level, but the Observation Level on the third and final Observation Date is 105.00. Therefore, the notes will be called at $10.00 plus the Call Premium of $6.153 = $16.153 per unit.

Notes Are Not Called on Any Observation Date

Example 4 - The notes are not called on any Observation Date and the Ending Value is less than the Threshold Value. The Redemption Amount will be less, and possibly significantly less, than the principal amount. For example, if the Ending Value is 50.00, the Redemption Amount per unit will be:

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-7 of product supplement EQUITY STR-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

	§	If the notes are not automatically called, you will lose up to 100% of the principal amount.
	§	Your investment return is limited to the return represented by the applicable Call Premium 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 is lower than the public offering price of the notes. The public offering price of the notes exceeds 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-14, 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 was determined by reference to our internal pricing models when the terms of the notes were set. This estimated value was based on market conditions and other relevant factors existing at that time, 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 was not determined by reference to credit spreads for our conventional fixed-rate debt. The internal funding rate that was 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 have used 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 had an adverse effect on the economic terms of the notes and the initial estimated value of the notes on the pricing date, and could have an adverse effect on 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 Underlying Fund holds the stocks of foreign companies. Therefore, your return on the notes may be affected by factors affecting the international securities markets, including emerging markets. In addition, exchange rate movements may adversely impact the value of notes.

Autocallable Strategic Accelerated Redemption Securities^® TS-6

Autocallable Strategic Accelerated Redemption Securities^®
Linked to the VanEck^® Gold Miners ETF, due June 30, 2028

	§	The sponsor, publisher or investment advisor of the Underlying Fund or the NYSE® Arca Gold Miners Index® (the “Underlying Index”) may adjust the Underlying Fund or the Underlying Index in a way that could adversely affect the price of the Underlying Fund and consequently, the return on the notes, and they have 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 held by 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.
	§	Risks associated with the Underlying Index or the securities held by the Underlying Fund will affect the price of the Underlying Fund and hence, the value of the notes.
	§	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 the Notes—Anti-Dilution and Discontinuance Adjustments Relating to Underlying Funds” beginning on page PS-27 of product supplement EQUITY STR-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-40 of product supplement EQUITY STR-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

A limited number of securities may affect the price of the Underlying Fund, and the Underlying Index is not necessarily representative of the gold and silver mining industry.

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 value of the notes.

While the securities included in the Underlying Index are common stocks, American Depositary Receipts (“ADRs”) or global depositary receipts (“GDRs”) of companies generally considered to be involved in various segments of the gold and silver mining industry, the securities included in the Underlying Index may not follow the price movements of the entire gold and silver mining industry 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 gold and silver mining industry generally increase in value.

The notes will be subject to small-capitalization or mid-capitalization companies risk.

The Underlying Fund may invest in companies that may be considered small-capitalization or mid-capitalization companies. These companies often have greater stock price volatility, lower trading volume and less liquidity than large-capitalization companies and therefore the Underlying Fund’s share price may be more volatile than an investment in stocks issued by large-capitalization companies. Stock prices of small-capitalization or mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business and economic developments, and the stocks of small-capitalization or mid-capitalization companies may be thinly traded, making it difficult for the Underlying Fund to buy and sell them. In addition, small-capitalization or mid-capitalization companies are typically less stable financially than large-capitalization companies and may depend on a small number of key personnel, making them more vulnerable to loss of personnel. Small-capitalization or mid-capitalization companies are often subject to less analyst coverage and may be in early, and less predictable, periods of their corporate existences. Such companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and less competitive strengths than large-capitalization companies and are more susceptible to adverse developments related to their products. These factors could adversely affect the price of the Underlying Fund during the term of the notes, which may adversely affect the value of your notes.

NYSE Arca, Inc. (“NYSE Arca”), the sponsor and compiler of the Underlying Index, retains significant control and discretionary decision-making over the Underlying Index and is responsible for decisions regarding the interpretation of and amendments to the rules of the Underlying Index, which may have an adverse effect on the price of the Underlying Fund, the market value of the notes and the amount payable on the notes.

NYSE Arca is the compiler of the Underlying Index and, as such, is responsible for the day-to-day management of the Underlying Index and for decisions regarding the interpretation of the rules governing the Underlying Index. NYSE Arca has the discretion to make

Autocallable Strategic Accelerated Redemption Securities^® TS-7

Autocallable Strategic Accelerated Redemption Securities^®
Linked to the VanEck^® Gold Miners ETF, due June 30, 2028

operational adjustments to the Underlying Index and to the components of the Underlying Index, including discretion to exclude companies that otherwise meet the minimum criteria for inclusion in the Underlying Index. In addition, NYSE Arca retains the power to supplement, amend in whole or in part, revise or withdraw the rules of the Underlying Index at any time, any of which may lead to changes in the way the Underlying Index is compiled or calculated or adversely affect the Underlying Index in another way. Any of these adjustments to the Underlying Index or the rules or the Underlying Index may adversely affect the composition of the Underlying Index, the price of the Underlying Fund, the market value of the notes and the amount payable on the notes. The index sponsor of the Underlying Index has no obligation to take the needs of any buyer, seller or holder of the notes into consideration at any time.

The performance of the Underlying Fund may be adversely influenced by gold and silver prices, which may change unpredictably and adversely affect the value of the notes in unforeseeable ways.

Most or all of the securities held by the Underlying Fund are issued by companies in the gold and silver mining industry. Although there is no direct correlation between the price of the Underlying Fund and gold and silver prices and the price of the Underlying Fund is not necessarily representative of gold and silver price, the prices of the Underlying Fund may be adversely affected by gold prices and silver prices. Those prices are subject to volatile price movements over short periods of time, represent trading in commodities markets, which are substantially different from equities markets, and are affected by numerous factors. These include economic factors, including the structure of and confidence in the global monetary system, expectations of the future rate of inflation, the relative strength of, and confidence in, the U.S. dollar (the currency in which the prices of gold and silver are generally quoted), interest rates and gold and silver borrowing and lending rates, and global or regional economic, financial, political, regulatory, judicial, or other events.

Gold prices and silver prices may also be affected by industry factors such as industrial and jewelry demand, lending, sales and purchases of gold and silver by the official sector, including central banks and other governmental agencies and multilateral institutions which hold gold and silver, levels of gold and silver production and production costs, and short-term changes in supply and demand because of trading activities in the gold and silver markets. It is not possible to predict the aggregate effects of all or any combination of these factors. Any negative developments with respect to these factors may have an adverse effect on gold and silver prices and, as a result, on the prices of the Underlying Fund. In addition, the value of the notes may be subject to greater volatility and be more adversely affected by a single economic, political or regulatory occurrence affecting gold and silver prices than a different investment linked to a more broadly diversified group of commodities. All of these factors could adversely affect the price of the Underlying Fund and, therefore, the return on the notes.

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 the Notes— Anti-Dilution and Discontinuance Adjustments Relating to Underlying Funds—Discontinuance of or Material Change to an Underlying Fund” beginning on page PS-31 of product supplement EQUITY STR-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.

Description of the VanEck^® Gold Miners ETF

The VanEck^® Gold Miners ETF is an investment portfolio maintained and managed by VanEck^® ETF Trust (the “VanEck Trust”). Van Eck Associates Corporation (“Van Eck”) is the investment adviser to the Underlying Fund. Prior to September 1, 2021, the VanEck^® Gold Miners ETF’s name was the VanEck Vectors^® Gold Miners ETF. The Underlying Fund is an exchange-traded fund that is listed and trades on the NYSE Arca under the ticker symbol “GDX.”

Information provided to or filed with the SEC by the VanEck Trust pursuant to the Securities Act and the Investment Company Act 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 Underlying Fund seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the NYSE^® Arca Gold Miners Index^®. The Underlying Index, calculated by NYSE Arca, is a modified market capitalization-weighted index consisting of common stocks and ADRs of publicly traded companies involved primarily in mining for gold and silver.

The Underlying Fund normally invests at least 80% of its total assets in common stocks and ADRs of companies involved in the gold and silver mining industry. The Underlying Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed. The Underlying 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. The returns of the Underlying Fund may be affected by certain management fees and other expenses, which are detailed in its prospectus.

The Underlying Fund may choose to concentrate its investments in a particular industry or group of industries to the extent that the Underlying Index concentrates in an industry or group of industries.

Correlation

The Underlying Index is a theoretical financial calculation, while the Underlying Fund is an actual investment portfolio. The performance of the Underlying Fund and the Underlying Index will vary somewhat due to transaction costs, market impact, corporate actions (such as mergers and spin-offs) and timing variances. The Underlying 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 Underlying 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.

Description of the NYSE^® Arca Gold Miners Index^®

The Underlying Index was developed by the NYSE Amex (formerly the American Stock Exchange) and is calculated, maintained and published by the NYSE Arca. The Underlying Index is reported by Bloomberg under the ticker symbol “GDM.” The index benchmark was 500.00 at the close of trading on December 20, 2002.

Objectives and Guiding Principles Underlying the Underlying Index

The Underlying Index is a modified market capitalization weighted index comprised of publicly traded companies involved primarily in the mining of gold or silver. The Underlying Index includes common stocks, ADRs or GDRs of selected companies that are involved in mining for gold and silver and that are listed for trading and electronically quoted on a major stock market that is accessible by foreign investors. Generally, this includes exchanges in most developed markets and major emerging markets, and includes companies that are cross-listed, i.e., both U.S. and Canadian listings. NYSE Arca will use its discretion to avoid exchanges and markets that are considered “frontier” in nature or have major restrictions to foreign ownership. The index includes companies that derive at least 50% of their revenues from gold mining and related activities (40% for companies that are already included in the index). Also, the index will maintain an exposure to companies with a significant revenue exposure to silver mining in addition to gold mining, which will not exceed 20% of the index weight at each rebalance. Only companies with market capitalization greater than $750 million that have a daily average trading volume of at least 50,000 shares and an average daily value traded of at least $1 million over the past three months are eligible for inclusion in the Underlying Index. Starting in December 2013, for companies already included in the index, the market capitalization requirement at each rebalance will be $450 million, the average daily volume requirement will be at least 30,000 shares over the past three months and the average daily value traded requirement will be at least $600,000 over the past three months. NYSE Arca has the discretion to not include all companies that meet the minimum criteria for inclusion.

Index Calculation

The Underlying Index is calculated on a price return basis using a modified market capitalization weighting methodology divided by a divisor. The divisor was determined on the initial capitalization base of the index at the base level and may be adjusted as a result of corporate actions and composition changes. The index is calculated on a price return, gross total return, net total return and short net total return basis in multiple currencies (USD, AUD, EUR, GBP, INR, JPY). The current index level would be calculated by dividing the current modified index market capitalization by the index divisor. The divisor was determined off of the initial capitalization base of the index and the base level. The divisor is updated as a result of corporate actions and composition changes.

Index Maintenance

Removal of constituents. Components will be removed from the Underlying Index during the quarterly review if either (1) the market capitalization falls below $450 million or (2) the traded average daily shares for the previous three months is less than 30,000 shares and the average daily traded value for the previous three months is less than $600,000.

Selected line. Only one listing is permitted per company and the listing representing the company’s ordinary shares is generally used. If an ADR, GDR, or U.S. cross-listing is available for a given stock and it satisfies the minimum liquidity requirements, that ADR, GDR, or U.S. cross-listing will be used instead of the locally listed ordinary share. This logic will be followed even in the cases where the stock’s local listing has a greater liquidity than the ADR, GDR, or U.S. cross-listing. If multiple share classes are available for a particular listing line, the shares outstanding for each class will be added up and be attributed to the most liquid class. There is no rules-based consideration of the amount of free float shares available for each company. Instead, the index administrator evaluates, on a discretionary basis, the amount of free float shares available to the public while performing its review of the universe.

Periodical update of weighting. The Underlying Index is weighted based on the market capitalization of each of the component stocks, modified to conform to the following asset diversification requirements, which are applied in conjunction with the scheduled quarterly adjustments to the index as described above. The information utilized in this modification process will be taken from the close of trading on the second Friday of the rebalance month:

1. The weight of any single component stock may not account for more than 20% of the total value of the Underlying Index;

2. The components stocks are split into two subgroups – (1) Large and (2) Small, ranked by their unadjusted market capitalization weight in the index. Large stocks are defined as having a starting index weight greater than or equal to 5%. Small stocks are defined as having a starting index weight below 5%;

3. The final aggregate weight of those component stocks which individually represent more than 4.5% of the total value of the Underlying Index may not account for more than 45% of the total Underlying Index value.

Diversification Rule 1: If any component stock exceeds 20% of the total value of the Underlying Index, then all stocks greater than 20% of the Underlying Index are reduced to represent 20% of the value of the Underlying Index. The aggregate amount by which all component stocks are reduced is redistributed proportionately across the remaining stocks that represent less than 20% of the index value. After this redistribution, if any other stock then exceeds 20%, the stock is set to 20% of the index value and the redistribution is repeated.

If there is no component stock over 20% of the total value of the Underlying Index to start, then Diversification Rule 1 is not executed.

Diversification Rule 2: The components are sorted into two groups – (1) Large components, with a starting index weight of 5% or greater, and (2) Small components, with a weight of under 5% (after any adjustments for Diversification Rule 1).

If there are no components that classify as Large components after Diversification Rule 1 is run, then Diversification Rule 2 is not executed. Alternatively, if the starting aggregate weight of the Large components after Diversification Rule 1 is run is not greater than 45% of the starting index weight, then Diversification Rule 2 is not executed.

If Diversification Rule 2 is indeed executed, then the (1) large group and (2) small group will represent 45% and 55%, respectively, of the final index weight. This will be adjusted for through the following process:

1.The weight of each of the large stocks will be scaled down proportionately (with a floor of 5%) so that the aggregate weight of the large components will be reduced to represent 45% of the Underlying Index. If any large component stock falls below a weight equal to the product of 5% and the proportion by which the stocks were scaled down following this distribution, then the weight of the stock is set equal to 5% and the components with weights greater than 5% will be reduced proportionately.

2. The weight of each of the small components will be scaled up proportionately from the redistribution of the large components. If any small component stock exceeds a weight equal to the product of 4.5% and the proportion by which the stocks were scaled down following this distribution, then the weight of the stock is set equal to 4.5%. The redistribution of weight to the remaining stocks is repeated until the entire amount has been redistributed.

Corporate Actions. The Underlying Index may be adjusted in order to maintain the continuity of the index level and the composition. The underlying aim is that the index continues to reflect as closely as possible the index’s objective of identifying and selecting stocks from a particular market segment that have a greater potential for capital appreciation. Adjustments take place in reaction to events that occur with constituents in order to mitigate or eliminate the effect of that event on the index performance.

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 will 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, 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.

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, resulted 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 amount you receive at maturity or upon an automatic call, 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.

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 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 STR-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 STR-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.

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.

In addition, this opinion is subject to customary assumptions about the Trustee’s authorization, execution and delivery of the indenture and the genuineness of signature, and to such counsel’s reliance on CIBC and other sources as to certain factual matters, all as stated in the opinion letter of such counsel dated June 6, 2023, which has been filed as Exhibit 5.2 to CIBC’s Registration Statement on Form F-3 filed with the SEC on June 6, 2023.

In the opinion of Mayer Brown LLP, when the notes have been duly completed in accordance with the indenture and issued and sold as contemplated by this term sheet and the accompanying product supplement, prospectus supplement and prospectus, the notes will constitute valid and binding obligations of CIBC, entitled to the benefits of the indenture, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles. This opinion is given as of the date hereof and is limited to the laws of the State of New York. This opinion is subject to customary assumptions about the Trustee’s authorization, execution and delivery of the indenture and such counsel’s reliance on CIBC and other sources as to certain factual matters, all as stated in the legal opinion dated June 6, 2023, which has been filed as Exhibit 5.1 to CIBC’s Registration Statement on Form F-3 filed with the SEC on June 6, 2023.
