Any capitalized term not defined herein shall have the meaning set forth in the preliminary pricing supplement to which the term sheet relates (se e h yperlink below). 1 SEC File No. 333 - 285508 | November 16, 2025 This term sheet, which gives a brief summary of the terms of the notes, relates to, and should be read in conjunction with, t he preliminary pricing supplement dated November 14, 2025, the Product Supplement dated March 25, 2025, the Prospectus Supplement dated March 25, 2025, and to the Prospectus dated to March 25, 202 5. DATES November 21, 2025 Offering Period Closes: On or about November 21, 2025 Pricing Date: On or about November 26, 2025 Settlement Date: On or about November 24, 2026 Valuation Date: On or about November 30, 2026 Maturity Date: Approximately 1 Year Term: INVESTMENT OBJECTIVE The objective of the notes is to provide clients the potential for leveraged participation in any upside performance of the R efe rence Asset, while offering limited downside protection against a slight to moderate decline in the Reference Asset over the term of the notes. As such, the notes may be sui table for investors with a bullish view of the Reference Asset over the term of the notes. The performance of the notes may not be consistent with the investment objective. TERMS 200.00% Upside Leverage Factor: 12.00% Maximum Return: $1,120.00 Maximum Redemption Amount: The closing level of the Reference Asset on the Pricing Date. Initial Level: 90% of the Initial Level Buffer Level: 10.00% Accordingly, you will receive the principal amount of your notes at maturity only if the level of the Reference Asset doe s not decrease by more than 10.00% over the term of the notes. If the Final Level of the Reference Asset is less than its Buffe r Level, you will receive less than the principal amount of your notes at maturity and you could lose up to 90.00% of the princ ipa l amount of your notes. Buffer Percentage: The closing level of the Reference Asset on the Valuation Date. Final Level: If the Final Level of the Reference Asset is greater than its Initial Level and the Percentage Change of the Reference Asset multiplied by the Upside Leverage Factor is greater than or equal to the Maximum Return, the payment at maturity for each $1, 000 in principal amount of the notes will equal the Maximum Redemption Amount. If the Final Level of the Reference Asset is greater than or equal to its Initial Level and the Percentage Change of the Refe ren ce Asset multiplied by the Upside Leverage Factor is less than the Maximum Return, then the amount that investors will receive a t maturity for each $1,000 in principal amount of the notes will equal: $1,000 + [$1,000 x (Percentage Change of the Reference Asset x Upside Leverage Factor)] If the Final Level of the Reference Asset is less than its Initial Level, but is not less than its Buffer Level, then investo rs will, for each $1,000 in principal amount of the notes, receive the principal amount of $1,000 and no additional return. If the Final Level of the Reference Asset is less than its Buffer Level, then the amount that investors will receive at matur ity for each $1,000 in principal amount of the notes will equal: $1,000 + [$1,000 x (Percentage Change of the Reference Asset + Buffer Percentage)] In this case, investors will lose 1% of their principal for each 1% that the Final Level of the Reference Asset declines from its Initial Level in excess of 10.00%. You may lose up to 90.00% of the principal amount of your notes. Payment at Maturity: The Percentage Change of the Reference Asset, expressed as a percentage, is calculated using the following formula: (Final Level – Initial Level) / Initial Level Percentage Change:

2 Investors in these notes could lose a substantial portion of their investment at maturity if there has been a decline in the market value of the Reference Asset and the Final Level of the Reference Asset is less than its Buffer Level. We urge you to carefully review the documents described in “Additional Information” below, including the risk factors set forth and incorporated by reference therein, prior to making an investment decision. Principal at Risk: The notes will not be listed on any securities exchange. Although not obligated to do so, BMO Capital Markets Corp. (or one of its affiliates), plans to maintain a secondary market in the notes after the Settlement Date. Proceeds from a sale of notes prior to maturity may be less than the principal amount initially invested. Secondary Market: The risks summarized below are some of the most important factors to be considered prior to any purchase of the notes. Investors are urged to read all the risk factors related to the notes in the pricing supplement and the product supplement to which this term sheet relates. • You could lose up to 90% of the principal amount of your notes. If the Final Level of the Reference Asset is less than its Buffer Level, you will lose 1% of the principal amount for each 1% that the Final Level of the Reference Asset is less than its Initial Level in excess of the Buffer Percentage. • Your return on the notes is limited to the Maximum Redemption Amount, regardless of any appreciation in the levels of the Reference Asset. • Your return on the notes may be lower than the return on a conventional debt security of comparable maturity. • The notes are unsecured debt obligations of the Issuer and your investment is subject to the credit risk of the Issuer. • Our and our affiliates’ activities may conflict with your interests and may also adversely affect the value of the notes. • Our initial estimated value of the notes will be lower than the price to public, does not represent any future value of the notes, and may also differ from the estimated value of any other party. • The terms of the notes are not determined by reference to the credit spreads for our conventional fixed - rate debt. • The inclusion of the hedging profits, if any, in the initial price to public of the notes, as well as our hedging costs, is likely to adversely affect the price at which you can sell your notes. • You will not have any shareholder rights and will have no right to receive any securities represented by the Reference Asset at maturity. • We have no affiliation with the sponsor of the Reference Asset, and will not be responsible for their actions. • Changes that affect the Reference Asset will affect the market value of the notes and the amount you will receive at maturity. Adjustments to the Reference Asset could adversely affect the notes. The sponsor of the Reference Asset may make adjustments, discontinue or suspend calculations or publication of that Reference Asset, or discontinue of suspend maintenance of that Reference Asset at any time. • The notes will not be listed on any securities exchange. BMOCM may offer to purchase the notes in the secondary market, but is not required to do so. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the notes easily. • We and our affiliates may engage in hedging and trading activities related to the notes that could adversely affect our payment to you at maturity. Selected Risk Considerations:

3 Hypothetical Calculations for the Payment at Maturity: Examples of the Hypothetical Payment at Maturity for a $1,000 Investment in the notes The following table illustrates the hypothetical payments on a note at maturity. The hypothetical payments are based on a $1,000 investment in the note, a hypothetical Initial Level of 100.00, a hypothetical Upside Leverage Factor of 200.00%, a hypothetical Buffer Level of 90.00 (90.00% of the hypothetical Initial Level), the Maximum Return of 12.00%, the Maximum Redemption Amount of $1,120.00, and a range of hypothetical Final Levels and the effect on the payment at maturity. The hypothetical examples shown below are intended to help you understand the terms of the notes. The actual cash amount that you will receive at maturity will depend upon the Final Level of the Reference Asset. You may lose some or a significant portion of the principal amount at maturity. These examples do not give effect to any U.S. federal tax payments or brokerage commissions that you may be required to pay in connection with your purchase of the notes.
