Investment Highlights

Currency

CAD Denominated.

Reference Index

Solactive Canada Energy Select 75 AR Index. The Reference Index is an adjusted return index that aims to track the gross total return performance of the Solactive Canada Energy Select Index TR (the "Target Index"), subject to a reduction of a synthetic dividend of 75 index points per annum calculated daily in arrears on a 360 day basis at the time the Reference Index is calculated (the "Adjusted Return Factor").

Call Feature

The Notes will be automatically called by CIBC on a Call Date if the Reference Index Return on the applicable Valuation Date is greater than or equal to 5.00%. If the Notes are called by CIBC on any of the Call Dates, Investors will receive a minimum Fixed Return plus 5.00% of the amount, if any, by which the Reference Index Return exceeds such Fixed Return.

Fixed Return

The "Fixed Returns" are as follows:

Valuation Date	Fixed Return
April 23, 2027	23.50%
April 24, 2028	25.50%
April 23, 2029	27.50%
April 23, 2030	29.50%
April 23, 2031	31.50%
April 23, 2032	33.50%
April 25, 2033	35.50%

Potential Upside

If the Notes are not automatically called by CIBC and if the Reference Index Return at maturity is greater than or equal to 5.00%, Investors will receive a minimum return of 35.50% (annual compounded return of 4.44%), and will also receive 5.00% of the amount, if any, by which the Reference Index Return exceeds 35.50%.

Downside Exposure

If the Notes are not automatically called by CIBC and if the Reference Index Return is less than 5.00% and greater than or equal to -20.00% on the final Valuation Date, the Variable Return will be equal to 0.00% and Investors will receive the Principal Amount at maturity. If, however, the Reference Index Return is less than -20.00% on the final Valuation Date, Investors will receive less than the Principal Amount at maturity, subject to a minimum payment of $1.00 per Note.

Term	Available Until	Issue Date	Maturity Date (if not called)	Minimum Investment	How to Buy

The performance of the Reference Index reflects the gross total return performance of the Target Index as reduced by the Adjusted Return Factor. Investors will not have any right to receive any dividends or other distributions on any securities included in the Target Index. The annual dividend yield of the securities included in the Target Index was 3.02% for the 12 months ended April 10, 2026, which would represent aggregate dividends of 21.14% over the seven year term of the Notes, assuming the dividend yield remains consistent and the dividends are not reinvested.

Hypothetical Examples

The following hypothetical examples show how the Maturity Amount would be calculated under six different scenarios. The Reference Index Return will be calculated based on the performance of the Reference Index, which reflects the gross total return performance of the Target Index as reduced by the Adjusted Return Factor. These examples are for illustrative purposes only and should not be construed as an estimate or forecast of the performance of the Reference Index at any time during the term of the Notes or the Variable Return to be determined on any Valuation Date. The actual performance of the Reference Index will be different from these hypothetical examples and the differences may be material.

Example 1 – Notes are not called and the Reference Index Return is less than -20.00% on the final Valuation Date

In this example, the Notes are not automatically called by CIBC and Investors are entitled to receive a Maturity Amount of $70.00 per Note (annual compounded return of -4.97%) on the Maturity Payment Date. The Reference Index Return is less than -20.00% on the final Valuation Date; therefore, the Variable Return is equal to the negative Reference Index Return.

Reference Index Return

April 2027	April 2028	April 2029	April 2030	April 2031	April 2032	April 2033
-4.00%	-6.00%	-12.00%	-14.00%	-20.00%	-22.00%	-30.00%
Variable Return:		-30.00%
Maturity Amount:		$70.00

Example 2 – Notes are not called and the Reference Index Return is less than 5.00% and greater than or equal to -20.00% on the final Valuation Date

In this example, the Notes are not automatically called by CIBC and Investors are entitled to receive a Maturity Amount of $100.00 per Note (annual compounded return of 0.00%) on the Maturity Payment Date. The Reference Index Return is less than 5.00% and greater than or equal to -20.00% on the final Valuation Date; therefore, the Variable Return is 0.00%.

Reference Index Return

April 2027	April 2028	April 2029	April 2030	April 2031	April 2032	April 2033
-4.00%	-6.00%	-12.00%	-14.00%	-20.00%	-22.00%	-20.00%
Variable Return:		0.00%
Maturity Amount:		$100.00

Example 3 – Notes are called in April 2027 and the Reference Index Return is less than or equal to the Fixed Return of 23.50% and greater than or equal to 5.00%

In this example, the Notes are automatically called by CIBC and Investors are entitled to receive a Maturity Amount of $123.50 per Note (annual compounded return of 23.50%) on the Call Date in April 2027. Since the Reference Index Return is less than or equal to the Fixed Return of 23.50% and greater than or equal to 5.00%, the Variable Return is equal to 23.50%.

Reference Index Return

April 2027	April 2028	April 2029	April 2030	April 2031	April 2032	April 2033
20.50%
(called)	N/A	N/A	N/A	N/A	N/A	N/A
Variable Return:	23.50%
Maturity Amount:	$123.50

Example 4 – Notes are called in April 2027 and the Reference Index Return of 33.50% is greater than the Fixed Return of 23.50%

In this example, the Notes are automatically called by CIBC and Investors are entitled to receive a Maturity Amount of $124.00 per Note (annual compounded return of 24.00%) on the Call Date in April 2027. Since the Reference Index Return is greater than the Fixed Return of 23.50%, the Variable Return is equal to (i) 23.50%, plus (ii) 5.00% x (33.50% - 23.50%), or 24.00%.

Reference Index Return

April 2027	April 2028	April 2029	April 2030	April 2031	April 2032	April 2033
33.50%
(called)	N/A	N/A	N/A	N/A	N/A	N/A
Variable Return:	24.00%
Maturity Amount:	$124.00

Example 5 – Notes mature in May 2033 and the Reference Index Return is less than or equal to the Fixed Return of 35.50% and greater than or equal to 5.00%

In this example, Investors are entitled to receive a Maturity Amount of $135.50 per Note (annual compounded return of 4.44%) on the Maturity Payment Date. Since the Reference Index Return is less than or equal to the Fixed Return of 35.50% and greater than or equal to 5.00%, the Variable Return is equal to 35.50%.

Reference Index Return

April 2027	April 2028	April 2029	April 2030	April 2031	April 2032	April 2033
-4.00%	-6.00%	-12.00%	-14.00%	-20.00%	-22.00%	16.00%

Variable Return: 35.50% Maturity Amount: $135.50

Example 6 – Notes mature in May 2033 and the Reference Index Return of 37.50% is greater than the Fixed Return of 35.50%

In this example, Investors are entitled to receive a Maturity Amount of $135.60 per Note (annual compounded return of 4.45%) on the Maturity Payment Date. Since the Reference Index Return is greater than the Fixed Return of 35.50%, the Variable Return is equal to (i) 35.50%, plus (ii) 5.00% x (37.50% - 35.50%), or 35.60%.

Reference Index Return

April 2027	April 2028	April 2029	April 2030	April 2031	April 2032	April 2033
-4.00%	-6.00%	-12.00%	-14.00%	-20.00%	-22.00%	37.50%

Variable Return: 35.60% Maturity Amount: $135.60

Reference Index

The Solactive Canada Energy Select 75 AR Index. The Solactive Canada Energy Select 75 AR Index is an adjusted return index that aims to track the gross total return performance of the Solactive Canada Energy Select Index TR, subject to a reduction of a synthetic dividend of 75 index points per annum calculated daily in arrears on a 360 day basis at the time the Reference Index is calculated. The Closing Level of the Reference Index on April 10, 2026 was 2,234.97. The Adjusted Return Factor divided by the level of the Reference Index was therefore equal to 3.36% on April 10, 2026. Over the term of the Notes, the sum of the Adjusted Return Factor of 75 points per annum will be approximately 525 index points, representing 23.49% of the level of the Reference Index on April 10, 2026. The Target Index is a gross total return index that reflects the applicable price changes of its constituent securities and any dividends and distributions paid in respect of such securities. For the calculation of the level of the Target Index, any dividends or other distributions paid on the constituent securities of the Target Index are assumed to be reinvested across all the constituent securities of the Target Index. There is no assurance of the ability of issuers of the securities comprising the Target Index to declare and pay dividends or make distributions in respect of the constituent securities of the Target Index or to sustain or increase such dividends and distributions at or above historical levels.

Issue Date

April 30, 2026

Maturity Date / Term

May 2, 2033 (7 years), provided that if such date is not a Business Day then the Maturity Date will be the immediately following Business Day, subject to the Notes being automatically called by CIBC on any Call Date and subject to the occurrence of a Market Disruption Event.

Call Dates and Valuation Dates

Based on an Issue Date of April 30, 2026, the Call Dates and Valuation Dates are as follows:

Valuation Dates	Call Dates
April 23, 2027	April 30, 2027
April 24, 2028	May 1, 2028
April 23, 2029	April 30, 2029

Valuation Dates	Call Dates
April 23, 2031	April 30, 2031
April 23, 2032	April 30, 2032
April 25, 2033	-

Provided that (i) if the Issue Date is postponed, each Call Date will be postponed by an equivalent number of days, and provided further that if any such Call Date is not both a Business Day and at least five Business Days following the applicable Valuation Date, the applicable Call Date will be postponed until the next Business Day that is at least five Business Days following the immediately preceding Valuation Date, in each case subject to the occurrence of a Market Disruption Event; and (ii) if any such Valuation Date is not an Exchange Day, then the applicable Valuation Date will be the immediately following Exchange Day, subject to the occurrence of a Market Disruption Event.

Call Feature

The Notes will be automatically called by CIBC on a Call Date if the Reference Index Return on the applicable Valuation Date is greater than or equal to 5.00%. If the Notes are called by CIBC on any of the Call Dates, Investors will receive a minimum Fixed Return plus 5.00% of the amount, if any, by which the Reference Index Return exceeds such Fixed Return.

Reference Index Return

The Reference Index Return will be a number (positive or negative), expressed as a percentage, determined as follows: (Index LevelVD – Index LevelID) / Index LevelID

where:

• the "Index LevelVD" will be the Closing Level on the applicable Valuation Date; and
• the "Index LevelID" will be the Closing Level on the Issue Date, provided that if the Issue Date is not an Exchange Day, the Index LevelID shall be determined on the next following Exchange Day (in which case references to the Closing Level on the Issue Date shall be deemed to refer to the Closing Level on such next following Exchange Day),

subject in each case to the provisions set out under "Market Disruption Events, Adjustments and Substitutions and Extraordinary Events" in the Prospectus.

Maturity Amount

Investors will be entitled to receive on the later of (a) the fifth Business Day following the final Valuation Date and (b) the Maturity Date (the "Maturity Payment Date") (or on a Call Date, if the Notes are automatically called by CIBC prior to the Maturity Date) in respect of each Note held by such Investor, an amount (the "Maturity Amount") equal to the product of:

i) $100.00; and ii) 100.00% plus the Variable Return,

subject to a minimum Maturity Amount of $1.00 per Note.

Variable Return

Positive Variable Return

If the Notes are called by CIBC on any of the Call Dates or the Reference Index Return is greater than or equal to 5.00% on the final Valuation Date preceding the Maturity Date in 2033, the "Variable Return" will be calculated as follows:

a) where the Reference Index Return is less than or equal to the applicable Fixed Return, the Variable Return will be equal to such Fixed Return; or b) where the Reference Index Return is greater than the applicable Fixed Return, the Variable Return will be equal to such Fixed Return, plus 5.00% of the amount by which the Reference Index Return exceeds such Fixed Return.

If the Notes are called by CIBC, Investors will not be entitled to receive any further return that they would have otherwise been entitled to receive if the Notes had not been called by CIBC.

Zero or Negative Variable Return

If the Notes are not called by CIBC and the Reference Index Return is less than 5.00% on the final Valuation Date preceding the Maturity Date in 2033, the Variable Return at maturity will be calculated as follows:

a) where the Reference Index Return is less than 5.00% and greater than or equal to -20.00% on the final Valuation Date, the Variable Return will be equal to 0.00%; or b) where the Reference Index Return is less than -20.00% on the final Valuation Date, the Variable Return will be equal to the Reference Index Return (which will be negative and result in a loss of a portion of the Principal Amount at maturity in these circumstances).

Secondary Market and Early Trading Amount

The Notes will not be listed on any securities exchange or quotation system. CIBC World Markets Inc. ("CIBC WM") intends to provide a daily secondary market for the sale of Notes to CIBC WM, but reserves the right not to do so, in its sole discretion, at any time without any prior notice to Investors. Under no circumstances will CIBC WM provide a secondary market for the Notes on or following a Valuation Date for the Notes if the Notes will be called by CIBC on the applicable Call Date. No other secondary market for the Notes will be available. Any sale in the secondary market may be made at a price less than the Principal Amount and will reflect the deduction of an early trading amount of 3.96% per Note initially, declining daily by 0.022% to 0.00% after 180 days. A sale of Notes originally purchased using the Fundserv network will be subject to certain additional procedures and limitations established by the Fundserv network.

An Investor who disposes of a Note to CIBC WM in the secondary market will generally be required to include in income as interest the amount, if any, by which the sale price exceeds the Principal Amount of such Note. Investors who dispose of a Note prior to maturity should consult their own tax advisors. See "Certain Canadian Federal Income Tax Considerations" in the Pricing Supplement.

An investment in the Notes involves risks not associated with conventional fixed rate or floating rate debt securities. None of CIBC, the Dealers or any of their respective affiliates, associates, or any other person or entity guarantees that holders of Notes will receive an amount equal to their original investment in the Notes or guarantees that any return will be paid on the Notes (subject to the minimum Maturity Amount of $1.00 per Note) at or prior to maturity of the Notes. Amounts paid to holders of the Notes will depend on the performance of the Reference Index. An investment in Notes is not suitable for a purchaser who does not understand (either on his or her own or with the help of a financial advisor) the terms of the Notes or the risks associated with the Notes and with structured products, options or similar financial instruments generally. See "Risk Factors" in the Prospectus and "Certain Risk Factors" in the Pricing Supplement. "Solactive" is a registered trademark of Solactive AG and has been licensed for use.

The Notes will not constitute deposits that are insured under the Canada Deposit Insurance Corporation Act or any other deposit insurance regime designed to ensure the payment of all or a portion of a deposit upon the insolvency of the deposit taking institution.

The principal amount of the Notes will not be fully guaranteed and, subject to the minimum Maturity Amount of $1.00 per Note, will be at risk. As a result, Investors could lose substantially all of their original investment in the Notes.

CIBC WM intends to provide a secondary market for the sale of Notes to CIBC WM but reserves the right not to do so, in its sole discretion, at any time without any prior notice to holders of Notes. There is no other market through which the Notes may be sold and purchasers may not be able to re-sell Notes.
