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

The initial estimated value of the notes as of the pricing date is expected to be between $9.335 and $9.711 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.

Summary

The Accelerated Return Notes^® Linked to the Global X Robotics & Artificial Intelligence ETF, due October  , 2024 (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 Global X Robotics & Artificial Intelligence ETF (the “Underlying Fund”), is greater than the Starting Value. 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 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.

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 $12.40 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. All payments on the notes are subject to issuer credit risk.

Redemption Amount Calculation Examples

Example 1
The Ending Value is 50.00, or 50.00% of the Starting Value:
Starting Value:	100.00
Ending Value:	50.00
	= $5.00 Redemption Amount per unit
Example 2
The Ending Value is 103.00, or 103.00% of the Starting Value:
Starting Value:	100.00
Ending Value:	103.00

= $10.90 Redemption Amount per unit

= $19.00, however, because the Redemption Amount for the notes cannot exceed the hypothetical Capped Value, the Redemption Amount will be $12.40 per unit

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

Valuation- and Market-related Risks

Conflict-related Risks

Market Measure-related Risks

Tax-related Risks

Additional Risk Factors

The securities held by the Underlying Fund are concentrated in one industry. All of the securities held by the Underlying Fund are issued by robotics & artificial Intelligence companies. Although an investment in the notes will not give holders any ownership or other direct interests in these securities, the return on an investment in the notes will be subject to certain risks associated with a direct equity investment in robotics & artificial Intelligence companies, including those discussed below. Accordingly, by investing in the notes, you will not benefit from the diversification which could result from an investment linked to companies that operate in multiple industries. In addition, because the securities held by the Underlying Fund are concentrated in one industry, they may be more susceptible to economic, market, political or regulatory occurrences affecting their relevant industry. As a result, their prices may increase or decrease at similar times and by similar magnitudes, and they may perform similarly over the term of the notes.

Adverse conditions in the robotics & artificial Intelligence industry may reduce your return on the notes.  All of the securities held by the Underlying Fund are issued by robotics & artificial Intelligence companies. These companies may have limited product lines, markets, financial resources or personnel, while engaging in significant amounts of spending on research and development. Robotics & artificial Intelligence companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. In addition, robotics and artificial intelligence technology could face increasing regulatory scrutiny in the future, which may limit the development of this technology and impede the growth of companies that develop and/or utilize this technology. Similarly, the collection of data from consumers and other sources could face increased scrutiny as regulators consider how the data is collected, stored, safeguarded and used. These companies face increased risk from trade agreements between countries that develop these technologies and countries in which customers of these technologies are based. Lack of resolution or potential imposition of trade tariffs may hinder the companies’ ability to successfully deploy their inventories. The customers and/or suppliers of these companies may be concentrated in a particular country, region or industry. Any adverse event affecting one of these countries, regions or industries could have a negative impact on these companies. These factors could adversely affect the robotics & artificial Intelligence industry and consequently, the price of the Underlying Fund and the return on the notes.

A limited number of securities may affect the price of the Underlying Fund, and the Underlying Index is not necessarily representative of the robotics & artificial Intelligence 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 return on the notes.

While the securities included in the Underlying Index are equity securities of robotics & artificial Intelligence companies, the securities included in the Underlying Index may not follow the price movements of the entire robotics & artificial Intelligence 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 robotics & artificial Intelligence industry 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, Global X Management Company LLC (“Global X Management”), which is the investment advisor of the Underlying Fund. 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-28 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 Global X Robotics & Artificial Intelligence ETF

The Underlying Fund seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the Indxx Global Robotics & Artificial Intelligence Thematic Index (the “Underlying Index”). The Underlying Index is designed to provide exposure to exchange-listed companies in developed markets, as defined by Indxx, LLC (“Indxx”), that are involved in the development of robotics and/or artificial intelligence, including companies involved in industrial robotics and automation, non-industrial robots, artificial intelligence and unmanned vehicles. The Underlying Fund is an exchange-traded fund that trades on The Nasdaq Stock Market under the ticker symbol “BOTZ.”

Information filed by the Underlying Fund with the SEC pursuant to the Securities Exchange Act of 1934 and the Investment Company Act can be located by reference to the SEC file numbers 333-151713 and 811-22209, respectively on the SEC’s website at http://www.sec.gov. In addition, information about the Underlying Fund may be obtained from other sources including, but not limited to, the Underlying Fund’s website. We are not incorporating by reference into this pricing supplement the website or any material it includes. Neither we nor the agent makes any representation that such publicly available information regarding the Underlying Fund is accurate or complete.

Global X Management uses a “passive” or indexing approach to try to achieve the Underlying Fund’s investment objective. Unlike many investment companies, the Underlying Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued. The Underlying Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Underlying Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the tracked becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Underlying Fund but not the Underlying Index.

Tracking error is the divergence of the Underlying Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the Underlying Fund’s portfolio and those included in the Underlying Index, pricing differences (including differences between a security’s price at the local market close and the Underlying Fund’s valuation of a security at the time of calculation of the Underlying Fund’s net asset value), differences in transaction costs, the Underlying Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest, tax gains or losses, changes to the Underlying Index or the costs to the Underlying Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Underlying Fund incurs fees and expenses, while the Underlying Index does not.

The Indxx Global Robotics & Artificial Intelligence Thematic Index

The Underlying Index is designed to provide exposure to exchange-listed companies in developed markets, as defined by Indxx, that are involved in the development of robotics and/or artificial intelligence (“AI”), including companies involved in industrial robotics and automation, non-industrial robots, AI and unmanned vehicles (collectively, “Robotics & AI Companies”), as defined by Indxx.

Eligible Universe of the Global Robotics & AI Index

Initial Universe

To be eligible for inclusion in the Underlying Index, companies must first be eligible for inclusion in the “Initial Universe” of such index. The Initial Universe of the Underlying Index includes among the most liquid and investable companies in accordance with the standard market capitalization and liquidity criteria associated with developed markets, as defined by Indxx. As of July 2018, companies from the following countries were eligible for inclusion in the Initial Universe of the Underlying Index: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, Luxembourg, the Netherlands, New Zealand, Norway, Portugal, Singapore, South Korea, Spain, Sweden, Switzerland, Taiwan, the United Kingdom and the United States.

As of February 2020, companies must have a minimum market capitalization of $300 million, a minimum average daily turnover for the last 6 months greater than or equal to $2 million and must have traded on 90% of the eligible trading days in the last 6 months in order to be eligible for inclusion in the Initial Universe of the Underlying Index. In case a company does not have a trading history of 6 months

due to its recent initial public offering (“IPO”), such company must have started trading at least 3 months before the start of the Underlying Index’s annual reconstitution/ rebalancing process and should have traded on 90% of the eligible trading days for the past 3 months.

Criteria Applied to the Initial Universe

The companies in the Initial Universe must then satisfy the following criteria:

Companies in the Initial Universe that satisfy the criteria discussed above form the “Eligible Universe” of the Underlying Index.

Identification of Robotics & AI Companies within the Eligible Universe

From the Eligible Universe, Indxx identifies Robotics & AI Companies by applying a proprietary analysis that consists of two primary components: sub-theme identification and company analysis. As part of the sub-theme identification process, Indxx analyzes industry reports, investment research and consumer data related to the robotics and AI industry in order to establish the sub-themes that are expected to provide the most exposure to the growth of the robotics and AI industry. As of February 2020, Indxx has identified the following four robotics and AI sub-themes:

In order to be included in the Underlying Index, a company must be identified as having significant exposure to one of these robotics and AI sub-themes, as determined by Indxx. In the second step of the process, companies are analyzed based on two primary criteria: revenue exposure and primary business operations. A company is deemed to have significant exposure to one of the robotics and AI sub-themes, and it accordingly constitutes a “Pure Play Robotics & AI Company,” if (i) it derives a significant portion (greater than 50%) of its revenue from one of the robotics and AI sub-themes or (ii) it has stated its primary business to be in products and services focused on one of the robotics and AI sub-themes, as determined by Indxx. Companies that have demonstrated these industries/segments to be growth focus areas through internal research and development investments, joint ventures, partnerships and/or acquisitions are also deemed to have significant exposure to one of the robotics and AI sub-themes, as determined by Indxx.

Selecting Constituents from the Eligible Universe’s Robotics & AI Companies

The Pure Play Robotics & AI Companies with the highest market capitalization will form the Underlying Index. The Underlying Index is capped at 100 companies. If fewer than 100 companies qualify as Robotics & AI Companies, all of these companies would be a part of the Underlying Index. If fewer than 30 companies qualify as Robotics & AI Companies, the index committee would consider a secondary list of companies with diversified revenue streams that (1) have a distinct business unit focused on robotics or AI and (2) have a core competency that is expected to augment the adoption of robotics or AI for inclusion until the count reaches 30.

Index Calculation and Weighting

The Underlying Index is calculated by means of the divisor methodology. The Underlying Index is weighted as follows:

Index Maintenance

Buffer Rules

To reduce turnover, the following buffer rules apply:

Reconstitution, Rebalancing and Reviews

The Underlying Index follows an annual reconstitution and rebalancing schedule. The new portfolio of index constituents becomes effective at the close of trading on the last trading day of June each year (the “Effective Day”). Weights are calculated at the close of the seventh trading day prior (six trading day prior) to the Effective Day. To capture IPOs and changes in the structure of a company’s business due to corporate actions, the composition of the Underlying Index is reviewed on a semi-annual basis.

Corporate Actions

Corporate actions (such as stock splits, special dividends, spin-offs and rights offerings) are applied to the Underlying Index on the ex-date or earlier as decided by the index committee.

The following graph shows the daily historical performance of the Underlying Fund on its primary exchange in the period from September 13, 2016, the date when the Underlying Fund began trading, through July 25, 2023. 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 July 25, 2023, the Closing Market Price of the Underlying Fund was $29.06. 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 may deliver the notes against payment therefor in New York, New York on a date that is greater than two business days 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 two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, if the initial settlement of the notes occurs more than two business days from the pricing date, purchasers who wish to trade the notes more than two business days 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:

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.

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 is a “specified entity” for purposes of the Hybrid Mismatch Proposals, as defined below (a “Non-Resident Holder”). For these purposes, a “specified shareholder” generally includes a person who (either alone or together with persons with whom that person is not dealing at arm’s length for the purposes of the Canadian Tax Act) owns or has the right to acquire or control or is otherwise deemed to own 25% or more of CIBC’s shares determined on a votes or fair market value basis, and an entity in respect of which CIBC is a “specified entity” generally includes (i) an entity that is a specified shareholder of CIBC (as defined above), (ii) an entity in which CIBC (either alone or together with entities with whom CIBC is not dealing at arm’s length for purposes of the Canadian Tax Act) owns or has the right to acquire or control or is otherwise deemed to own a 25% or greater equity interest, and (iii) an entity in which an entity described in (i) (either alone or together with entities with whom such entity is not dealing at arm’s length for purposes of the Canadian Tax Act) owns or has the right to acquire or control or is otherwise deemed to own a 25% or greater equity interest. Special rules which apply to non-resident insurers carrying on business in Canada and elsewhere are not discussed in this summary.

For greater certainty, this summary takes into account all specific proposals to amend the Canadian Tax Act publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof, including the proposals released on April 29, 2022 with respect to “hybrid mismatch arrangements” (the “Hybrid Mismatch Proposals”). This summary assumes that no amount paid or payable to a holder described herein will be the deduction component of a “hybrid mismatch arrangement” under which the payment arises within the meaning of proposed paragraph 18.4(3)(b) of the Canadian Tax Act contained in the Hybrid Mismatch Proposals. Investors should note that the Hybrid Mismatch Proposals are in consultation form, are highly complex, and there remains significant uncertainty as to their interpretation and application. There can be no assurance that the Hybrid Mismatch Proposals will be enacted in their current form, or at all.

This summary is supplemental to and should be read together with the description of material Canadian federal income tax considerations relevant to a Non-Resident Holder owning notes under “Material Income Tax Consequences—Canadian Taxation” in the accompanying prospectus and a Non-Resident Holder should carefully read that description as well.

This summary is of a general nature only and is not intended to be, nor should it be construed to be, legal or tax advice to any particular Non-Resident Holder. Non-Resident Holders are advised to consult with their own tax advisors with respect to their particular circumstances.

Based on Canadian tax counsel’s understanding of the Canada Revenue Agency’s administrative policies and having regard to the terms of the notes, interest payable on the notes should not be considered to be “participating debt interest” as defined in the Canadian Tax Act and accordingly, a Non-Resident Holder should not be subject to Canadian non-resident withholding tax in respect of amounts paid or credited or deemed to have been paid or credited by 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.

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, 2025.

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.
