Reference Portfolio
Reference asset	Ticker symbol
Solactive Canada Select Large Cap III 162 Index AR	SOLCS162

The Solactive Canada Select Large Cap III 162 Index AR is an adjusted return index. It aims to track the gross total return performance of the Solactive Canada Select Large Cap III Index TR (the "underlying index"), calculated in Canadian dollars, less an adjusted return factor of 162 index points per annum that will be calculated daily in arrears (the "adjusted return factor"). The underlying index is intended to track the performance of 16 large cap companies from the Canadian stock market. The closing level on March 31, 2026 was 3,687.08. The adjusted return factor divided by the closing level was therefore equal to 4.39% on March 31, 2026. Over the term of the notes, the sum of the adjusted return factor will be approximately 1,135 index points, representing 30.78% of the closing level on March 31, 2026.

The underlying index is a gross total return index that reflects the price changes of its constituent securities and the reinvestment in the underlying index of any dividends and distributions paid in respect of such securities. For the calculation of the level of the underlying index, any dividends or other distributions paid on the constituent securities of the underlying index are assumed to be reinvested across all the constituent securities of the underlying index. The composition of the underlying index is adjusted quarterly, ordinarily in February, May, August, and November, and is also subject to extraordinary adjustments in compliance with the rules of the index sponsor.

The dividend yield of the underlying index on March 31, 2026 was 3.04%, representing an aggregate dividend yield of approximately 21.30% over the term of the notes (assuming the dividend yield remains constant and the dividends are not reinvested). An investment in the notes does not represent a direct or indirect investment in the reference asset. You have no right or entitlement to the dividends or distributions paid on the reference asset.

Principal-at-risk Notes

How do the Notes work?

The following hypothetical examples demonstrate how the payment you may receive will be calculated and determined under four different scenarios. The hypothetical closing levels used in these examples are for illustrative purposes only and should not be construed in any way as estimates or forecasts of the future performance of the reference asset or the return that you might realize on the notes. All hypothetical examples assume that no events described under "Certain Additional Terms for Notes Linked to a Reference Index" in the income product supplement have occurred during the term. For ease of analysis, figures below have been rounded.

Barrier level/Coupon payment level	Autocall level
75.00% of the initial level	105.00% of the initial level

Example 1: Payment at Maturity (Negative Scenario)

Investor cash flow summary per note
(1) Principal amount paid	CAD $100.00
(2) Total coupons received
o Years 1-2: 2 coupons at 0.80% monthly
o Years 3-7: 0 coupons at 0.40% monthly	CAD $1.60
(3) Maturity payment received	CAD $42.00
(4) Total amount received = (2) + (3)	CAD $43.60
(5) Return on the notes (annualized)	-11.17%

In this hypothetical example, the closing level is below the autocall level on all autocall observation dates, so the notes are not redeemed early. Furthermore, it is above the coupon payment level on the first and second coupon observation dates and below the coupon payment level on all the others, so you would receive two of the coupon payments.

Lastly, the final level is at 42.00% of the initial level, which is below the barrier level, so the final reference asset return is -58.00%. Accordingly, you would receive a maturity payment of CAD $42.00 per note with coupons totalling CAD $1.60 per note over the term of the notes (which is equivalent to a compounded annual loss of 11.17% on the notes).

In this example, the maturity payment is calculated as follows:

$$
\begin{array}{l}
\text{Maturity payment} = \text{CAD} \$100.00 + (\text{CAD} \$100.00 \times \text{final reference asset return}) \
= \text{CAD} \$100.00 + (\text{CAD} \$100.00 \times -58.00\%) \
= \text{CAD} \$42.00
\end{array}
$$

Example 2: Payment at Maturity (Neutral Scenario)

Investor cash flow summary per note
(1) Principal amount paid	CAD $100.00
(2) Total coupons received ○ Years 1-2: 14 coupons at 0.80% monthly ○ Years 3-7: 30 coupons at 0.40% monthly	CAD $23.20
(3) Maturity payment received	CAD $100.00
(4) Total amount received = (2) + (3)	CAD $123.20
(5) Return on the notes (annualized)	3.02%

In this hypothetical example, the closing level is below the autocall level on all autocall observation dates, so the notes are not redeemed early. Furthermore, it is above the coupon payment level on forty-four of the coupon observation dates and below the coupon payment level on all the others, so you would receive forty-four of the coupon payments.

Lastly, the final level is at $81.00\%$ of the initial level, which is above the barrier level, so the final reference asset return is $-19.00\%$ . Accordingly, you would receive a maturity payment equal to the principal amount with coupons totalling CAD $23.20 per note over the term of the notes (which is equivalent to a compounded annual return of $3.02\%$ on the notes).

Example 3: Payment at Maturity (Positive Scenario)

Investor cash flow summary per note
(1) Principal amount paid	CAD $100.00
(2) Total coupons received ○ Years 1-2: 24 coupons at 0.80% monthly ○ Years 3-7: 60 coupons at 0.40% monthly	CAD $43.20
(3) Maturity payment received	CAD $100.00
(4) Total amount received = (2) + (3)	CAD $143.20
(5) Return on the notes (annualized)	5.26%

In this hypothetical example, the closing level is below the autocall level on all autocall observation dates, so the notes are not redeemed early. Furthermore, it is above the coupon payment level on all of the coupon observation dates, so you would receive all of the coupon payments.

Lastly, the final level is at $86.00\%$ of the initial level, which is above the barrier level, so the final reference asset return is $-14.00\%$ . Accordingly, you would receive a maturity payment equal to the principal amount with coupons totalling CAD $43.20 per note over the term of the notes (which is equivalent to a compounded annual return of $5.26\%$ on the notes).

Example 4: Automatic Early Redemption

Investor cash flow summary per note
(1) Principal amount paid	CAD $100.00
(2) Total coupons received
o Years 1-2: 9 coupons at 0.80% monthly
o Years 3-7: 0 coupons at 0.40% monthly	CAD $7.20
(3) Maturity payment received (early redemption)	CAD $100.00
(4) Total amount received = (2) + (3)	CAD $107.20
(5) Return on the notes (annualized)	9.63%

In this hypothetical example, the closing level is below the autocall level on all autocall observation dates until the ninth observation date. This results in the notes being redeemed early on the autocall payment date corresponding with the ninth observation date. Furthermore, it is above the coupon payment level on nine of the coupon observation dates, so you would receive nine of the coupon payments before the notes are redeemed.

Lastly, the closing level is at 112.00% of the initial level, which is above the autocall level, so the reference asset return is 12.00% and the notes are redeemed early for a value of CAD $100.00. Accordingly, you would receive a maturity payment equal to the principal amount with coupons totalling CAD $7.20 per note over the term of the notes (which is equivalent to a compounded annual return of 9.63% on the notes).
