NBC NOTE SECURITIES

NBC Auto Callable Note Securities (Maturity-Monitored Barrier) linked to the Solactive Equal Weight Canada Banks 5% AR Index, due on November 4, 2030

OFFER PERIOD:

October 16, 2025 to October 29, 2025

ISSUANCE DATE:

November 4, 2025

INVESTMENT HIGHLIGHTS:

• Reference Asset: The Reference Asset is the Solactive Equal Weight Canada Banks 5% AR Index, which aims to track the gross total return performance of the Solactive Equal Weight Canada Banks Index (the "TR Index"), reduced by an adjusted return factor of 5.00% per annum calculated daily in arrears (the "AR Factor").
• Call Threshold: 0.00%
• Participation Factor: 5.00%
• Variable Return: 5.00% of the amount by which the Reference Portfolio Return exceeds the Fixed Return
• Currency: Canadian dollars
• Early Trading Charge: $3.60 per Note Security, declining every 15 days by $0.30 to be $0.00 after 180 days from and including the Issuance Date
• Daily secondary market available under normal market conditions

The performance of the Reference Asset will vary higher or lower from the performance of the price return version of the TR Index (that is, a version that does not reflect the reinvestment of dividends and/or distributions paid on the equity securities making up the TR Index) over the term of the Note Securities, depending on whether the impact of the dividends and/or other distributions reinvested in the TR Index is greater or less than the impact of the deduction of the AR Factor over the term of the Note Securities.

As of October 3, 2025, the dividends and/or distributions paid on account of the constituent securities that comprise the TR Index represented an annual indicative yield of approximately 3.61%.

The foregoing dividend yield information is for comparative purposes only and is not an indication of any future dividends and/or distributions that might be paid or payable on such constituent securities.

Listing and Secondary Market:	The Note Securities will not be listed on any securities exchange or quotation system. NBF intends to maintain until the Final Valuation Date (or until a Call Valuation Date, if the Note Securities are automatically called (i.e., redeemed) prior to the Maturity Date), under normal market conditions, a daily secondary market for the Note Securities. If the price or the level of a Reference Asset is not reported or published or, in an applicable case, if the trading in a Reference Asset is disrupted or suspended, or if any other Market Disruption Event occurs, NBF will generally deem that normal market conditions do not exist. NBF may, in its sole discretion, stop maintaining a market for the Note Securities at any time without any prior notice to Holders. There can be no assurance that a secondary market will develop or, if one develops, that it will be liquid.
In addition, any sale of Note Securities facilitated by NBF may be subject to an early trading charge, deductible from the sale proceeds of the Note Securities. Holders who have purchased Note Securities using the Fundserv network will be limited to the Fundserv network to sell Note Securities. Holders will thereby need to initiate an irrevocable request to sell the Note Securities to NBF. Provided the order is received before 1:00 p.m. (Montréal time) or such other time as may be established by NBF (the “Sale Deadline Time”) on any Business Day, the request will be treated on the same day. Any request received after such time or on a day that is not a Business Day will be deemed to be a request sent and received before the Sale Deadline Time on the following Business Day.
Eligibility for Investment:	Eligible for RRSPs, RRIFs, RESPs, RDSPs, DPSPs, TFSAs and FHSAs. See “Eligibility for Investment” in the Prospectus.

Suitability for Investment

The Note Securities are not suitable for all investors. In determining whether the Note Securities are a suitable investment for you, please consider that:

• the Note Securities provide no protection for your original principal investment and if the Reference Portfolio Return is lower than the Call Threshold on every Call Valuation Date and is lower than the Barrier on the Final Valuation Date, you will receive an amount which is less than your original principal investment on the Maturity Payment Date;
• your Note Securities will be redeemed automatically prior to the Maturity Date if on any Call Valuation Date the Reference Portfolio Return is equal to or higher than the Call Threshold;
• any positive Reference Portfolio Return in excess of the Variable Return Threshold on either a Call Valuation Date or the Final Valuation Date will be multiplied by a Participation Factor which will result in a Holder receiving less than 100% of that excess amount, as the case may be;
• your investment strategy should be consistent with the investment features of the Note Securities;
• your investment time horizon should correspond with the term of the Note Securities; and
• your investment will be subject to the risk factors summarized in the section “Risk Factors” in the Prospectus.

Risk Factors

The Note Securities differ from conventional debt and fixed income investments; repayment of the entire Principal Amount is not guaranteed. The Note Securities entail downside risk and are not designed to be alternatives to conventional debt or fixed income investments or money market instruments.

Investing in the Note Securities involves risks described under “Risk Factors” in the Prospectus, including, without limitation, the section therein entitled “Certain Risk Factors related to the Index Linked Note Securities”. Investors should be mindful of the following additional risks involved with an investment in the Note Securities:

• The performance of the Reference Asset will be affected by the ability of issuers comprising the TR Index to pay dividends and/or distributions;
• The deduction of the AR Factor may cause the Reference Asset to underperform the price return version of the TR Index; and
• As a consequence of the deduction of the fixed AR Factor, there is a risk of an adverse investment outcome under the Note Securities compared to securities linked to the price return version of the TR Index with similar parameters.

Purchasers are urged to read the information about these risks, together with the other information in the Prospectus, before investing in the Note Securities. Holders who are not prepared to accept the risks described in the Prospectus should not invest in the Note Securities.

Use of the Reference Asset

The Reference Asset is the intellectual property (including any registered trademarks) of Solactive AG, which is used under license. The Note Securities are not sponsored, promoted, sold or supported in any other manner by Solactive AG nor does Solactive AG offer any express or implicit guarantee or assurance either with regards to the results of using the Reference Asset and/or Reference Asset trademark or the Closing Level of the Reference Asset at any time or in any other respect.

NOTICE

The Note Securities 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 insolvency of the deposit taking institution.

Amounts paid to Holders will depend on the performance of the Reference Portfolio. None of the Bank, its affiliates, the Dealers, or any other person or entity guarantees that Holders will receive an amount equal to their original investment in the Note Securities or guarantees that any return will be paid on the Note Securities at maturity. Since the Note Securities are not protected and the Principal Amount will be at risk (other than the minimum Maturity Redemption Payment of 1% of the Principal Amount), it is possible that Holders could lose some or substantially all of their original investment in the Note Securities.

For the various risks associated with such an investment, please see the “Risk Factors” section of this document and the “Risk Factors” section in the Prospectus. Any prospective investor must be able to bear the risks involved and must meet the suitability requirements of the Note Securities. Please see the section “Suitability of the Note Securities for Investors” in the Prospectus.
