AMENDED AND RESTATED FINAL TERMS

THESE AMENDED AND RESTATED FINAL TERMS HAVE BEEN CREATED SOLELY AS A MATTER OF RECORD TO RECORD THE FINAL TERMS OF THE NOTES AS AT THE DATE OF ISSUE. NO OFFER OF ANY OF THE NOTES IS BEING MADE BY THE ISSUER PURSUANT TO THIS DOCUMENT OR OTHERWISE AND THE ISSUER DOES NOT ACCEPT ANY ADDITIONAL OBLIGATIONS TO NOTEHOLDERS IN RELATION TO THIS DOCUMENT.

UK MIFIR product governance / Retail investors, professional investors and ECPs target market – Solely for the purposes of the manufacturer's product approval process, the target market assessment in respect of the Notes has led to the conclusion that: (i) the target market for the Notes is retail clients, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 ("EUWA"), and eligible counterparties, as defined in the FCA Handbook Conduct of Business Sourcebook ("COBS)"), and professional clients, as defined in Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA ("UK MiFIR"); and (ii) all channels for distribution of the Notes are appropriate, including investment advice, portfolio management, non-advised sales and pure execution services, subject to the suitability and appropriateness obligations of the Distributor (as defined below) under COBS, as applicable. Any person subsequently offering, selling or recommending the Notes (a "Distributor") should take into consideration the manufacturer's target market assessment; however, a Distributor subject to the FCA Handbook Product Intervention and Product Governance Sourcebook (the "UK MiFIR Product Governance Rules") is responsible for undertaking its own target market assessment in respect of the Notes (by either adopting or refining the manufacturer's target market assessment) and determining appropriate distribution channels, subject to the Distributor's suitability and appropriateness obligations under COBS, as applicable.

PRIIPs Regulation – PROHIBITION OF SALES TO EEA RETAIL INVESTORS – The Notes are not intended to be offered, sold or otherwise made available to, and should not be offered, sold or otherwise made available to, any retail investor in the European Economic Area ("EEA"). For these purposes, a "retail investor" means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of MiFID II; (ii) a customer within the meaning of Directive (EU) 2016/97, as amended, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Regulation (EU) 2017/1129, as amended (the "Prospectus Regulation"). Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the "PRIIPs Regulation") for offering or selling the Notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

• 2.3 What are the key risks that are specific to the issuer: The key risks relating to the Issuer are set out below:
• Inflation, Interest Rates and Economic Growth: As inflation eased in 2024, central banks began reducing interest rates in the back half of the year. While interest rates will gradually begin to provide financial relief to clients, unemployment continues to be a headwind. Commercial office real estate, particularly in the United States, continues to face challenges due to post COVID-19 hybrid work arrangements and high interest rates, negatively impacting office asset valuations. The impact of interest rates on Canadian mortgages is discussed under the risk factor entitled "Canadian consumer debt and the housing market" below and in the "Credit risk – Real estate secured personal lending" section on pages 63-65 of CIBC's 2024 Annual Report. CIBC is closely monitoring the macroeconomic environment and assessing its potential adverse impact on its clients, counterparties and businesses.
• • Geopolitical risk: The level of geopolitical risk escalates at certain points in time. While the specific impact on the global economy and on global credit and capital markets would depend on the nature of the event, in general, any major event could result in instability and volatility, leading to widening spreads, declining equity valuations, flight to safe-haven currencies and increased purchases of gold. In the short run, market disruption could hurt the net income of the Issuer's trading and nontrading market risk positions. Geopolitical risk could reduce economic growth, and in combination with the potential impacts on commodity prices and the recent rise of protectionism, could have serious negative implications for general economic and banking activities and may have adverse impacts on the Issuer's business, results of operations and financial condition.
• • Climate Risk: The physical effects of climate change along with regulations designed to mitigate its negative impacts will have a measurable impact on communities and the economy. The physical risks of climate change resulting from severe

weather events and systemic issues such as rising sea levels can impact CIBC's profitability through disruptions in its own operations and damage to critical infrastructure. Transition risks, which arise as society adjusts towards a low-carbon future, can impact the financial health of its clients as changes in policy and technology aimed at limiting global warming can increase their operating costs and reduce profitability, while translating into potentially higher credit losses for CIBC. CIBC is also exposed to reputational risks due to changing stakeholder expectations related to action or inaction in addressing climate-related risks.

• • Technology, information and cyber security risk: Financial institutions like the Issuer are evolving their use of technology and business processes to improve the client experience and streamline operations. At the same time, cyber threats and the associated financial, reputation and business interruption risks have also increased. The Issuer continues to actively manage these risks through strategic risk reviews, enterprise-wide technology and information security programs, with the goal of maintaining overall cyber-resilience that prevents, detects, and responds to threats such as data breaches, malware, unauthorized access, and denial-of-service attacks, which can result in damage to the Issuer systems and information, theft or disclosure of confidential information, unauthorized or fraudulent activity, and service disruption.
• • The Issuer's results could be affected by legislative and regulatory developments in the jurisdictions where the Issuer conducts business: As the Issuer operates in a number of jurisdictions and its activities are subject to extensive regulation in those jurisdictions, the Issuer's financial performance and position could be affected by changes to law, statutes, regulations or regulatory policies, rules or guidelines in those jurisdictions where the Issuer operates, including changes in their interpretation, implementation or enforcement.
• • Risks related to legal proceedings and other contingencies: In the ordinary course of its business, the Issuer is a party to a number of legal proceedings, including regulatory investigations, in which claims for substantial monetary damages are asserted against the Issuer and its subsidiaries. It is possible that the Issuer could receive judicial or regulatory decisions or judgments that result in fines, criminal prosecution, damages and other costs that could damage its reputation and have a negative impact on the Issuer's results.
• • The Issuer relies on third parties to provide certain key components of its business infrastructure: Third parties provide key components of the Issuer's business infrastructure such as Internet connections and network access and other voice or data communication services. Given the high volume of transactions the Issuer processes on a daily basis, certain errors may be repeated or compounded before they are discovered and successfully rectified. Despite any contingency plans the Issuer may have in place, the Issuer's ability to conduct business may be adversely impacted by a disruption in the infrastructure that supports the Issuer's businesses and the communities in which they are located.
• • Borrower and Counterparty Risk Exposure: The ability of the Issuer to make payments in connection with any Notes is subject to general credit risks, including credit risks of borrowers. The failure to effectively manage credit risk across the Issuer's products, services and activities can have a direct, immediate and material impact on the Issuer's earnings and reputation.

• 3.1.4 Relative seniority of the securities in the Issuer's capital structure in the event of insolvency: The Notes are Senior Notes and constitute deposit liabilities of the Issuer for purposes of the Bank Act. The Notes will rank pari passu with all deposit liabilities of the Issuer (except as otherwise prescribed by law) without any preference amongst themselves. The Notes are not deposits insured under the CDIC Act. The Notes are not subject to Canada's bank resolution powers.
• 3.1.5 Description of restrictions on free transferability of the securities: The Notes are freely transferable (subject to all applicable laws). However, there are restrictions on the offer and sale of the Notes. The Issuer and Canadian Imperial Bank of Commerce, London Branch, 150 Cheapside, London EC2V 6ET (the "Dealer") have agreed restrictions on the offer, sale and delivery of the Notes and on distribution of offering materials in the European Economic Area, the United Kingdom, Canada and the United States of America.
• 3.2 Where will the securities be traded? Application will be made by the Issuer (or on its behalf) for the Notes to be admitted to trading on the Main Market of the London Stock Exchange plc and to the Official List of the UK Financial Conduct Authority ("FCA") with effect on or around the issue date.
• 3.3 What are the key risks that are specific to the securities? Key risks relating to the Notes include:
• • No interest or additional amounts may be payable under the Notes: Prospective investors should note that if a Coupon Barrier Event has occurred in respect of a Interest Valuation Date then no interest will be paid on the Notes on the corresponding Interest Payment Date. An investor in such Notes, in the context of its own financial position, must be capable of holding such Notes to maturity with no income stream in the form of interest payments. As there may be no periodic payment of interest to the Noteholders, any increase in the value of the Underlying Asset will not be crystallized until the Notes are redeemed and the Notes may fall in value at any time prior to redemption.
• • Risks related to redemption of the Notes: The redemption method applicable to the Final Redemption Amount may be different to the redemption method applicable to the Early Redemption Amount. The Early Redemption Amount or Final Redemption Amount, as applicable, may be calculated by reference to a Redemption Payoff. The calculation of such Redemption Payoff may be linked to the value of one or more Underlying(s) that have been selected under the relevant Redemption Payoff. The performance of the Underlying(s) will consequently affect the Early Redemption Amount or Final Redemption Amount an investor will receive. As a result, the Early Redemption Amount or Final Redemption Amount may be less than the nominal amount of the Notes and Noteholders may lose all or part of the amount of the capital invested.

Where a Note is subject to early redemption, it may be redeemed at its Fair Market Value Redemption Amount, which may be different from the amount due on the scheduled redemption or maturity date. Save in respect of Notes where the Fair Value Redemption Amount is determined by reference to a fixed percentage, the Fair Market Value Redemption Amount in respect of a Note will be an amount equal to the fair market value of the Note (subject to a minimum of zero). Following the early redemption of the Notes, a Noteholder may not be able to reinvest the redemption proceeds at an equivalent rate of return to the Notes being redeemed and may only be able to do so at a significantly lower rate or in worse investment conditions.

• • Risks related to Payoff Features: The Linked Interest Rate and/or Redemption Method applicable to the Linked Interest or Linked Redemption of the Notes is linked to the value of the Underlying(s) specified under the relevant Interest Payoff Conditions and/or Redemption Method Conditions. Negative performance of the Underlying(s) will consequently affect the value of the Linked Interest Rate and/or Redemption Amount. Principal and/or interest paid as a result of the application of the relevant Interest Payoff Conditions and/or Redemption Method Conditions may be less (and in certain circumstances, significantly less) than investors' initial investment in the relevant Notes and could be as low as zero.
• • The Notes may redeem early following an "automatic early redemption (autocall) event": The Notes may be automatically redeemed prior to the scheduled redemption date if the level, price, value or performance of the Underlying Asset breaches the Early Redemption Barrier on the relevant Early Redemption Observation Date. In the event that such an automatic redemption (autocall) event occurs, investors will be paid an early redemption amount equal to the Calculation Amount or such other amount specified in the Conditions. In such case, investors may not be able to reinvest the proceeds from an investment at a comparable return and/or with a comparable interest rate for a similar level of risk. Potential investors should consider such reinvestment risk in light of other available investments before they purchase the Notes. In the event that an automatic redemption (autocall) event does not occur during the term of the Notes, investors may lose some or all of their investment at maturity, depending on the performance of the Underlying Asset(s) and the Conditions of their Notes.
• • Risks related to Disruption Events: The Notes may be subject to risks related to additional disruption events, market disruption events, disrupted days and other events that have a material effect on the Notes (the "Disruption Events"). The occurrence of any Disruption Event may result in the postponement of the relevant observation date relating to any Underlying or affected component Underlying of a Basket, the postponement of the relevant payment date for interest or redemption or the redemption of the Notes by the Issuer. The amount to be paid following any postponement of the payment date will not be adjusted to take into account any interest or other sum in respect of the postponement of the payment. Any postponement of the observation date or payment date or any amendment to the Conditions may have an adverse effect on the value of the Notes and may also adversely affect the investors' investment schedule, timetable or plans in relation to which the payment dates of the Notes are connected.
• • The tax treatment of the Notes is uncertain: The tax treatment of the Notes is uncertain and the tax treatment applicable to such Notes may change before the maturity, exercise or redemption (as applicable) of the Notes. Prospective investors should consult their own independent tax advisors before making an investment in the Notes.
• • Risks associated with Index Linked Notes: Noteholders should be aware that (i) they may receive no or a limited amount of interest, (ii) payment of principal or interest may occur at a different time than expected and (iii) they may lose all or a substantial portion of their investment. In addition, the movements in the level of the index or indices may be subject to significant fluctuations that may not correlate with changes in the relevant index or indices and the timing of changes in the relevant level of the index or indices may affect the actual yield of the Notes, even if the average level is consistent with their expectations. In general, the earlier the change in the level of an index, the greater the effect on yield.

The market price of such Notes may be volatile and may depend on the time remaining to the redemption date and the volatility of the level of the index or indices. The level of the index or indices may be affected by the economic, financial and political events in one or more jurisdictions, including but not limited to the stock exchange(s) or quotation system(s) on which any securities comprising the index or indices may be traded. Noteholders are exposed to the risk that changes in the levels of the index or indices may adversely affect the value of the Notes and as a result, could lose all or part of their investment.

Indices are comprised of a synthetic portfolio of shares, bonds, currency exchange rates, commodities and other assets and, as such, the performance of an index is dependent upon the performance of components of such index, which may include interest rates, currency developments, political factors, market factors such as the general trends in capital markets or broad based indices and (in the case of equity securities) company-specific factors such as earnings position, market position, risk situation, shareholder structure and distribution policy. If an index does not perform as expected, this will materially and adversely affect the value of the Notes.

If the amount of principal and/or interest payable is determined in conjunction with a multiplier greater than one or by reference to some other leverage factor, the effect of changes in the level of the index or the indices on principal and/or interest payable will be magnified.

Returns on Notes that reference indices may not reflect the return an investor would realise if it actually owned the relevant assets comprising the components of the index or owned a different form of interest in the relevant index and in the same proportion as the weighting of such relevant assets in the index or, as the case may be, indices in an index basket. For example, if the components of the indices are equity securities, Noteholders will not receive any dividends paid or distributions made on those equity securities and will not participate in the return on those dividends or distributions unless the relevant index takes dividends into account for purposes of calculating the relevant level. Similarly, an investor in the

Notes will not benefit from any voting rights or rights to receive cash dividends or other distributions or rights that it would have benefited in case of direct investment in the securities. Accordingly, holders of Notes that reference indices as Underlying Assets may receive a lower payment on the redemption/settlement of such Notes than such holders would have received if they had invested in the components of the index directly or other comparable instruments linked to the index.

The Calculation Agent may determine that an event giving rise to a Disrupted Day and/or if an Additional Disruption Event has occurred at any relevant time. Any such determination may have an effect on the timing of valuation and consequently the value of the Notes and/or may delay any applicable payments or settlement. Prospective purchasers should review the Conditions and the Final Terms to ascertain whether and how such provisions apply to the Notes.

The Index Sponsor of any relevant Index can add, delete or substitute the assets comprised in the Index or amend in any other way the methodology of the Index. Investors should be aware that those decisions by the Index Sponsor may adversely affect the value of the Notes (for example, if the components of the indices are equity securities, if a newly added company performs significantly worse or better than the company it replaces). No Index Sponsor of any relevant Index has to consider interests of Noteholders in calculating and revising the Index. If an Index Adjustment Event occurs, prospective purchasers should note that the Issuer may redeem the Notes early at the Early Redemption Amount specified in the Final Terms.
