Additional Offering Details
Issuer	Bank of Montreal
Issuer rating	Moody’s: Aa2; S&P: A+; DBRS: AA (long-term deposits > 1 year).
Reference asset	Solactive Equal Weight Canada Banks 35 AR Index (ticker: SOLBEW35).
Reference asset description	The Solactive Equal Weight Canada Banks 35 AR Index is an adjusted return index. It aims to track the gross total return performance of the Solactive Equal Weight Canada Banks Index (the “underlying index”), calculated in Canadian dollars, less an adjusted return factor of 35 index points per annum that will be calculated daily in arrears (the “adjusted return factor”). The underlying index is an equally-weighted free-float market capitalization index of common stock of Canadian issuers. The methodology of the underlying index provides that the constituent securities fulfill the following criteria: primarily listed on the Toronto Stock Exchange; classified by the index sponsor as “Major Banks” or “Regional Banks”; have a minimum free-float market capitalization of CAD $10 billion for new index members and CAD $5 billion for current index members; and have a minimum average daily trading value of CAD $10 million, as calculated by the index sponsor. The closing level on March 31, 2026 was 781.91. The adjusted return factor divided by the closing level was therefore equal to 4.48% on March 31, 2026. Over the term of the notes, the sum of the adjusted return factor will be approximately 245 index points, representing 31.37% of the closing level on March 31, 2026. The dividend yield of the underlying index on March 31, 2026 was 3.20%, representing an aggregate dividend yield of approximately 22.43% over the term of the notes (assuming the dividend yield remains constant and the dividends are not reinvested).
Currency of notes	Canadian dollar (CAD).
Stated principal amount	CAD $100.00 per note.
Minimum investment	CAD $100,000.00 (1,000 notes).

Term	Approximately seven (7) years.
Observation and Payment Dates	See "Observation and Payment Dates" below.
Participation rate	5.00%
Autocall level	100.00% of the initial level.
Automatic early redemption	The notes will be automatically redeemed on any autocall payment date if, on the corresponding autocall observation date, the closing level is at or above the autocall level. On any such redemption, you will receive a cash payment equal to the stated principal amount multiplied by the sum of (1) 100.00% and (2) the variable return applicable to the relevant autocall payment date, in accordance with the following formula: $$= CAD\$100.00 \times (100.00\% + \text{variable return})$$

	See “Observation and Payment Dates” below.
Excess return	For any given autocall payment date, the excess return is calculated in accordance with the following formula: $$= \text{max}(0, (\text{reference asset return} - \text{fixed return}) \times \text{participation rate})$$
Initial level	The closing level on the issue date.
Final level	The closing level on the final valuation date.
Reference asset return	In respect of any given date, the reference asset return shall be determined in accordance with the following formula: $$= \frac{\text{closing level} - \text{initial level}}{\text{initial level}}$$
Final reference asset return	The reference asset return on the final valuation date.
Barrier level	70.00% of the initial level.
Barrier event	Monitoring at maturity only.
Payment at maturity	If the notes have not been redeemed, you will receive at maturity for each note you then hold:
- If the final level is at or above the autocall level, a maturity payment of at least CAD $176.30 as defined in the automatic early redemption section.
- If the final level is at or above the barrier level but below the autocall level, a maturity payment equal to CAD $100.00.
- If the final level is below the barrier level, a maturity payment directly linked to the performance of the reference asset. The maturity payment will be equal to the following formula, subject to a minimum payment of CAD $1.00: $$= \text{CAD} \times 100.00 + (\text{CAD} \times 100.00 \times \text{final reference asset return})$$ If the notes have not been redeemed early, and the final level is below the barrier level, the payment you receive at maturity may be significantly below the stated principal amount of your notes and may be as little as CAD $1.00.

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 autocallable product supplement have occurred during the term. For ease of analysis, figures below have been rounded.

Barrier level	Autocall level
70.00% of the initial level	100.00% of the initial level

Example 1: Payment at Maturity (Negative Scenario)

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, the final level is at 41.00% of the initial level, which is below the barrier level, so the final reference asset return is -59.00%. Accordingly, you would receive a maturity payment of CAD $41.00 per note (which is equivalent to a compounded annual loss of 11.95% on the notes).

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

$$
\begin{array}{l}
\text{Maturity payment} = \text{CAD } \$100.00 + (\text{CAD } \$100.00 \times \text{ final reference asset return}) \
= \text{CAD } \$100.00 + (\text{CAD } \$100.00 \times -59.00\%) \
= \text{CAD } \$41.00
\end{array}
$$

Example 2: Payment at Maturity (Neutral Scenario)

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, 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 of CAD $100.00 per note (which is equivalent to a compounded annual return of 0.00% on the notes).

Example 3: Payment at Maturity (Positive Scenario)

In this hypothetical example, the closing level is below the autocall level on all autocall observation dates until the final valuation date, where it is above. This results in the notes being redeemed in accordance with the autocall conditions on the final valuation date. Furthermore, the final level is at 112.00% of the initial level, which is above the autocall level, so the final reference asset return is 12.00%.

Principal-at-risk Notes

Because the final reference asset return on the final valuation date is less than the fixed return, the excess return will be zero, and accordingly, you would receive a maturity payment equal to the principal amount multiplied by the sum of (1) 100.00% and (2) the fixed return of 76.30%. Accordingly, you would receive a maturity payment of CAD $176.30 per note (which is equivalent to a compounded annual return of 8.43% on the notes).

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

$$
\begin{array}{l}
\text{Maturity payment} = \text{CAD } \$100.00 \times (100.00\% + \text{variable return}) \
= \text{CAD } \$100.00 \times (100.00\% + \text{fixed return} + \text{excess return}) \
= \text{CAD } \$100.00 \times (100.00\% + 76.30\% + 0.00\%) \
= \text{CAD } \$176.30
\end{array}
$$

Example 4: Automatic Early Redemption

In this hypothetical example, the closing level is below the autocall level on all autocall observation dates until the fourth autocall observation date. This results in the notes being redeemed early on the fourth autocall payment date. Furthermore, the closing level is at 151.00% of the initial level, which is above the autocall level, so the reference asset return is 51.00%.

Because the reference asset return on the fourth autocall observation date is greater than the fixed return, the excess return will be greater than zero, and accordingly, you would receive an autocall payment equal to the principal amount multiplied by the sum of (1) 100.00%, (2) the fixed return of 43.60% and (3) the excess return. The excess return will be equal to 0.37%, which is calculated as the product of (1) the participation rate of 5.00% and (2) the reference asset return of 51.00% minus the fixed return of 43.60%. Accordingly, you would receive an autocall payment of CAD $143.97 per note (which is equivalent to a compounded annual return of 9.53% on the notes).

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

$$
\begin{array}{l}
\text{Autocall payment} = \text{CAD } \$100.00 \times (100.00\% + \text{variable return}) \
= \text{CAD } \$100.00 \times (100.00\% + \text{fixed return} + \text{excess return}) \
= \text{CAD } \$100.00 \times (100.00\% + 43.60\% + 5.00\% \times (51.00\% - 43.60\%)) \
= \text{CAD } \$143.97
\end{array}
$$
