Pricing Supplement dated October 3, 2025 (To Product Supplement No. ELN-1 dated March 25, 2025, Prospectus Supplement dated March 25, 2025 and Prospectus dated March 25, 2025)

The notes do not bear interest. The amount that you will be paid on your notes on the stated maturity date (November 5, 2026, subject to postponement) is based on the performance of the VanEck^® Gold Miners ETF as measured from the trade date (October 3, 2025) to and including the determination date (November 3, 2026, subject to postponement).

If the final underlier level on the determination date is greater than or equal to the threshold level of 85.00% of the initial underlier level ($77.08, which was the closing price of the underlier on the trade date), the return on your notes will be positive and you will receive, for each $1,000 principal amount of your notes, the threshold settlement amount of $1,158.50. However, if the final underlier level is less than the threshold level, the return on your notes will be negative and you will lose approximately 1.1765% of the principal amount of your notes for every 1% that the final underlier level has declined below the threshold level. You could lose some, or all, of the principal amount of your notes.

To determine your payment at maturity, we will calculate the underlier return, which is the percentage increase or decrease in the final underlier level from the initial underlier level. On the stated maturity date, for each $1,000 principal amount of your notes, you will receive an amount in cash equal to:

The notes will not be listed on any securities exchange and are designed to be held to maturity.

The estimated initial value of the notes determined by us as of the trade date, which we refer to as the initial estimated value, is $983.28 per $1,000 principal amount of notes, which is less than the original issue price. However, as discussed in more detail in this pricing supplement, the actual value of the notes at any time will reflect many factors and cannot be predicted with accuracy. See “Estimated Value of the Notes” in this pricing supplement.

The notes involve risks not associated with an investment in conventional debt securities. See “Selected Risk Considerations” beginning on page PS-9 herein and “Risk Factors” beginning on page PS-5 of the accompanying product supplement, page S-2 of the prospectus supplement and page 9 of the prospectus.

The notes are the unsecured obligations of Bank of Montreal, and, accordingly, all payments on the notes are subject to the credit risk of Bank of Montreal. If Bank of Montreal defaults on its obligations, you could lose some or all of your investment. The notes are not insured by the Federal Deposit Insurance Corporation, the Deposit Insurance Fund, the Canada Deposit Insurance Corporation or any other governmental agency.

The notes are not bail-inable notes and are not subject to conversion into our common shares or the common shares of any of our affiliates under subsection 39.2(2.3) of the Canada Deposit Insurance Corporation Act.

Neither the Securities and Exchange Commission nor any state securities commission or other regulatory body has approved or disapproved of these notes or passed upon the accuracy or adequacy of this pricing supplement or the accompanying product supplement, prospectus supplement and prospectus. Any representation to the contrary is a criminal offense.

Estimated Value of the Notes

Our estimated initial value of the notes equals the sum of the values of the following hypothetical components:

The internal funding rate used in the determination of the initial estimated value generally represents a discount from the credit spreads for our conventional fixed-rate debt. The value of these derivative transactions is derived from our internal pricing models. These models are based on factors such as the traded market prices of comparable derivative instruments and on other inputs, which include volatility, dividend rates, interest rates and other factors. As a result, the estimated initial value of the notes is based on market conditions at the time it is calculated.

For more information about the estimated initial value of the notes, see “Selected Risk Considerations” below.

Hypothetical Examples

The following examples are provided for purposes of illustration only. The examples should not be taken as an indication or prediction of future investment results and are intended merely to illustrate the impact that the various hypothetical final underlier levels on the determination date could have on the cash settlement amount at maturity, assuming all other variables remain constant and are not intended to predict the actual final underlier level.

The information in the following examples reflects hypothetical rates of return on the notes assuming that they are purchased on the original issue date at a price equal to the principal amount and held to the stated maturity date. If you sell your notes in any secondary market prior to the stated maturity date, your return will depend upon the market value of your notes at the time of sale, which may be affected by a number of factors that are not reflected in the examples below. Such factors are described under “Selected Risk Considerations—The Value of the Notes Prior to Maturity Will Be Affected by Numerous Factors, Some of Which Are Related in Complex Ways” below. In addition, the estimated value of the notes will be less than the original issue price. For more information on the estimated value of your notes, see “Estimated Value of the Notes” above and “Selected Risk Considerations” below.

The information in the examples also reflects the key terms and assumptions in the box below.

The actual performance of the underlier over the term of your notes, as well as the actual cash settlement amount, if any, may bear little relation to the hypothetical examples shown below or to the historical closing prices of the underlier shown elsewhere in this pricing supplement. For information about the historical closing prices of the underlier during recent periods, see “The Underlier—Historical Information” below.

Also, the hypothetical examples shown below do not take into account the effects of applicable taxes.

The levels in the left column of the table below represent hypothetical final underlier levels and are expressed as percentages of the initial underlier level. The amounts in the right column represent the hypothetical cash settlement amounts, based on the corresponding hypothetical final underlier level (expressed as a percentage of the initial underlier level), and are expressed as percentages of the principal amount of a note (rounded to the nearest one-thousandth of a percent). Thus, a hypothetical cash settlement amount of 115.850% means that the value of the cash payment that we would deliver for each $1,000 of the outstanding principal amount of the notes on the stated maturity date would equal 115.850% of the principal amount of a note, based on the corresponding hypothetical final underlier level and the assumptions noted above.

As shown in the table above:

The following chart shows a graphical illustration of the hypothetical cash settlement amounts (expressed as percentages of the principal amount of your notes) that we would pay on your notes on the stated maturity date, if the final underlier level (expressed as percentages of the initial underlier level) were any of the hypothetical levels shown on the horizontal axis. The chart shows that any hypothetical final underlier level of less than 85.000% (the section left of the 85.000% marker on the horizontal axis) would result in a hypothetical cash settlement amount of less than 100.000% of the principal amount of your notes (the section below the 100.000% marker on the vertical axis) and, accordingly, in a loss of principal to the holder of the notes. The chart also shows that any hypothetical final underlier level of greater than or equal to 85.000% (the section right of the 85.000% marker on the horizontal axis) would result in a limited return on your investment.

Selected Risk Considerations

The notes involve risks not associated with an investment in conventional debt securities. Some of the risks that apply to an investment in the notes are summarized below, but we urge you to read the more detailed explanation of the risks relating to the notes generally in the “Risk Factors” section of the accompanying product supplement and prospectus supplement. You should reach an investment decision only after you have carefully considered with your advisors the appropriateness of an investment in the notes in light of your particular circumstances.

Risks Relating To The Notes Generally

If The Final Underlier Level Is Less Than The Threshold Level, You Will Lose Some, And Possibly All, Of The Principal Amount Of Your Notes At Maturity.

We will not repay you a fixed amount on the notes on the stated maturity date. The cash settlement amount will depend on the direction of and percentage change in the final underlier level relative to the initial underlier level and the other terms of the notes. Because the value of the underlier will be subject to market fluctuations, the cash settlement amount may be more or less, and possibly significantly less, than the principal amount of your notes.

If the final underlier level is less than the threshold level, the cash settlement amount will be less than the principal amount and you will lose approximately 1.1765% of the principal amount for every 1% that the final underlier level is less than the threshold level. As a result, if the final underlier level is less than the threshold level, you will lose some, and possibly all, of the principal amount per note at maturity. This is the case even if the value of the underlier is greater than or equal to the initial underlier level or the threshold level at certain times during the term of the notes.

You Will Receive The Threshold Settlement Amount Only If The Final Underlier Level Is Greater Than Or Equal To The Threshold Level.

You will receive the threshold settlement amount only if the final underlier level is greater than or equal to the threshold level. If the final underlier level is less than the threshold level, then you will not receive the threshold settlement amount.

The Potential Return On The Notes Is Limited By The Threshold Settlement Amount.

The potential return on the notes is limited by the threshold settlement amount, regardless of how significantly the final underlier level exceeds the initial underlier level. The underlier could appreciate from the trade date through the determination date by significantly more than the percentage represented by the threshold settlement amount, in which case an investment in the notes will underperform a hypothetical alternative investment providing a 1-to-1 return based on the performance of the underlier.

The Notes Do Not Pay Interest.

The notes will not pay any interest. Accordingly, you should not invest in the notes if you seek current income during the term of the notes.

The Notes Are Subject To Credit Risk.

The notes are our obligations and are not, either directly or indirectly, an obligation of any third party. Any amounts payable under the notes are subject to our creditworthiness and you will have no ability to pursue the shares of the underlier or any securities held by the underlier for payment. As a result, our actual and perceived creditworthiness may affect the value of the notes and, in the event we were to default on our obligations under the notes, you may not receive any amounts owed to you under the terms of the notes.

The U.S. Federal Income Tax Consequences Of An Investment In The Notes Are Unclear.

There is no direct legal authority regarding the proper U.S. federal income tax treatment of the notes and we do not plan to request a ruling from the Internal Revenue Service (the “IRS”) with respect to the notes. Consequently, significant aspects of the tax treatment of the notes are uncertain, and the IRS or a court might not agree with our intended treatment of them, as described in “United States Federal Income Tax Considerations” below. If the IRS were successful in asserting an alternative treatment of the notes, the tax consequences of the ownership and disposition of the notes, including the timing and character of income recognized by U.S. investors, and the withholding tax consequences to non-U.S. investors, might be materially and adversely affected. Even if the treatment of the notes is respected, a note may be treated as a “constructive ownership transaction,” with potentially adverse consequences described below under “United States Federal Income Tax Considerations.” Moreover, future legislation, Treasury regulations or IRS guidance could adversely affect the U.S. federal income tax treatment of the notes, possibly retroactively.

You should review carefully the sections of this pricing supplement and the accompanying product supplement entitled “United States Federal Income Tax Considerations” and consult your tax advisor regarding the U.S. federal income tax consequences of an investment in the notes, as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

The Stated Maturity Date Will Be Postponed If The Determination Date Is Postponed.

The determination date will be postponed if the originally scheduled determination date is not a scheduled trading day or if the calculation agent determines that a market disruption event has occurred or is continuing on the determination date. If such a postponement occurs, the stated maturity date will be postponed. See “General Terms of the Notes—Consequences of a Market Disruption Event; Postponement of a Valuation Date—Notes Linked to a Single Underlier” and “—Payment Dates” in the accompanying product supplement.

Risks Relating To The Estimated Value Of The Notes And Any Secondary Market

The Estimated Value Of The Notes On The Trade Date, Based On Our Proprietary Pricing Models, Will Be Less Than The Original Issue Price.

Our initial estimated value of the notes is only an estimate, and is based on a number of factors. The original issue price of the notes may exceed our initial estimated value, because costs associated with offering, structuring and hedging the notes are included in the original issue price, but are not included in the estimated value. These costs will include any underwriting discount and selling concessions and the cost of hedging our obligations under the notes through one or more hedge counterparties (which may be one or more of our affiliates). Such hedging cost includes our or our hedge counterparty’s expected cost of providing such hedge, as well as the profit we or our hedge counterparty expect to realize in consideration for assuming the risks inherent in providing such hedge.

The Terms Of The Notes Are Not Determined By Reference To The Credit Spreads For Our Conventional Fixed-Rate Debt.

To determine the terms of the notes, we use an internal funding rate that represents a discount from the credit spreads for our conventional fixed-rate debt. As a result, the terms of the notes are less favorable to you than if we had used a higher funding rate.

The Estimated Value Of The Notes Is Not An Indication Of The Price, If Any, At Which We, BMOCM Or Any Other Person May Be Willing To Buy The Notes From You In The Secondary Market.

Our initial estimated value of the notes is derived using our internal pricing models. This value is based on market conditions and other relevant factors, which include volatility of the underlier, dividend rates and interest rates. Different pricing models and assumptions, including those used by other market participants, could provide values for the notes that are greater than or less than our initial estimated value. In addition, market conditions and other relevant factors after the trade date are expected to change, possibly rapidly, and our assumptions may prove to be incorrect. After the trade date, the value of the notes could change dramatically due to changes in market conditions, our creditworthiness, and the other factors discussed in the next risk factor. These changes are likely to impact the price, if any, at which we, BMOCM or any other party would be willing to purchase the notes from you in any secondary market transactions. Our initial estimated value does not represent a minimum price at which we, BMOCM or any other party would be willing to buy your notes in any secondary market at any time.

For a period of approximately 3 months following issuance of the notes, the price, if any, at which we or our affiliates would be willing to buy the notes from investors, and the value that BMOCM may also publish for the notes through one or more financial information vendors and which could be indicated for the notes on any brokerage account statements, will reflect a temporary upward adjustment from our estimated value of the notes that would otherwise be determined and applicable at that time. This temporary upward adjustment represents a portion of (a) the hedging profit that we or our affiliates expect to realize over the term of the notes and (b) any underwriting discount and selling concessions paid in connection with this offering. The amount of this temporary upward adjustment will decline to zero on a straight-line basis over the 3-month period.

The Value Of The Notes Prior To Maturity Will Be Affected By Numerous Factors, Some Of Which Are Related In Complex Ways.

The value of the notes prior to stated maturity will be affected by the then-current value of the underlier, interest rates at that time and a number of other factors, some of which are interrelated in complex ways. The effect of any one factor may be offset or magnified by the effect of another factor. The following factors, which are described in more detail in the accompanying product supplement, are expected to affect the value of the notes: performance of the underlier; interest rates; volatility of the underlier; time remaining to maturity; currency exchange rates; and dividend yields on the securities held by the underlier. When we refer to the “value” of your notes, we mean the value you could receive for your notes if you are able to sell them in the open market before the stated maturity date.

In addition to these factors, the value of the notes will be affected by actual or anticipated changes in our creditworthiness. You should understand that the impact of one of the factors specified above, such as a change in interest rates, may offset some or all of any change in the value of the notes attributable to another factor, such as a change in the value of the underlier. Because numerous factors are expected to affect the value of the notes, changes in the value of the underlier may not result in a comparable change in the value of the notes.

The Notes Will Not Be Listed On Any Securities Exchange And We Do Not Expect A Trading Market For The Notes To Develop.

The notes will not be listed or displayed on any securities exchange. Although the agent and/or its affiliates may purchase the notes from holders, they are not obligated to do so and are not required to make a market for the notes. There can be no assurance that a secondary market will develop. Because we do not expect that any market makers will participate in a secondary market for the notes, the price at which you may be able to sell your notes is likely to depend on the price, if any, at which the agent is willing to buy your notes.

If a secondary market does exist, it may be limited. Accordingly, there may be a limited number of buyers if you decide to sell your notes prior to maturity. This may affect the price you receive upon such sale. Consequently, you should be willing to hold the notes to maturity.

Risks Relating To The Underlier

The Cash Settlement Amount Will Depend Upon The Performance Of The Underlier And Therefore The Notes Are Subject To The Following Risks, Each As Discussed In More Detail In The Accompanying Product Supplement.

The Notes Are Subject To Risks Relating To Non-U.S. Securities Markets With Respect To The Underlier.

Some of the equity securities composing the underlier are issued by non-U.S. companies in non-U.S. securities markets. Investments in securities linked to the value of such non-U.S. equity securities involve risks associated with the securities markets in the home countries of the issuers of those non-U.S. equity securities, including risks of volatility in those markets, governmental intervention in those markets and cross shareholdings in companies in certain countries. Also, there is generally less publicly available information about companies in some of these jurisdictions than there is about U.S. companies that are subject to the reporting requirements of the SEC, and generally non-U.S. companies are subject to accounting, auditing and financial reporting standards and requirements and securities trading rules different from those applicable to U.S. reporting companies. The prices of securities in non-U.S. markets may be affected by political, economic, financial and social factors in those countries, or global regions, including changes in government, economic and fiscal policies and currency exchange laws. 

The Notes Are Subject to Risks Relating to Emerging Markets with Respect to the Underlier.

Some of the equity securities composing the underlier have been issued by companies in countries based in emerging markets. Emerging markets pose further risks in addition to the risks associated with investing in foreign equity markets generally. Countries with emerging markets may have relatively unstable financial markets and governments; may present the risks of nationalization of businesses; may impose restrictions on currency conversion, exports or foreign ownership and prohibitions on the repatriation of assets; may pose a greater likelihood of regulation by the national, provincial and local governments of the emerging market countries, including the imposition of currency exchange laws and taxes; and may have less protection of property rights, less access to legal recourse and less comprehensive financial reporting and auditing requirements than more developed countries. The economies of countries with emerging markets may be based on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates. Local securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times. Moreover, the economies in such countries may differ unfavorably from the economy in the United States in such respects as growth of gross national product, rate of inflation, capital reinvestment, resources, self-sufficiency and balance of payment positions. The currencies of emerging markets may also be less liquid and more volatile than those of developed markets and may be affected by political and economic developments in different ways than developed markets. The foregoing factors may adversely affect the performance of companies based in emerging markets.

An Investment In The Notes Is Subject To Risks Associated With Investing In Stocks In The Gold And Silver Mining Industries.

All or substantially all of the equity securities composing the underlier are issued by companies whose primary line of business is directly associated with the gold and/or silver mining industries. As a result, the value of the notes may be subject to greater volatility and may be more adversely affected by a single economic, political or regulatory occurrence affecting these industries than a different investment linked to securities of a more broadly diversified group of issuers. Investments related to gold and silver are considered speculative and are affected by a variety of factors. Competitive pressures may have a significant effect on the financial condition of gold and silver mining companies. Also, gold and silver mining companies are highly dependent on the price of gold and silver bullion, respectively, and may be adversely affected by a variety of worldwide economic, financial and political factors. The price of gold has fluctuated in recent years and may continue to fluctuate substantially over short periods of time so the trading price of the shares of the underlier may be more volatile than other types of investments. Fluctuation in the prices of gold and silver may be due to a number of factors, including changes in inflation and changes in industrial and commercial demand for metals. Additionally, increased environmental or labor costs may depress the value of metal investments. In times of significant inflation or great economic uncertainty, gold, silver and other precious metals may outperform traditional investments such as bonds and stocks. However, in times of stable economic growth, traditional equity and debt investments could offer greater appreciation potential and the value of gold, silver and other precious metals may be adversely affected, which could in turn affect the underlier’s returns. If a natural disaster or other event with a significant economic impact occurs in a region where the companies in which the underlier invests operate, that disaster or event could negatively affect the profitability of these companies and, in turn, the underlier’s investment in them. These factors could affect the gold and silver mining industries and could affect the value of the equity securities held by the underlier and the price of the underlier during the term of the notes, which may adversely affect the value of your notes.

The Notes Are Subject To Currency Exchange Rate Risk With Respect To The Underlier.

The underlier is composed of some non-U.S. equity securities denominated in a non-U.S. currency and the prices of those securities are converted into U.S. dollars for purposes of calculating the value of the underlier. Therefore, investors in the notes will be exposed to currency exchange rate risk with respect to each of the currencies in which the non-U.S. equity securities held by the underlier trade. An investor’s net exposure will depend on the extent to which the currencies of the non-U.S. equity securities held by the underlier strengthen or weaken against the U.S. dollar and the relative weight of the non-U.S. equity securities denominated in those currencies. If, taking into account that weighting, the dollar strengthens against the currencies of the non-U.S. equity securities held by the underlier, the value of the underlier will be adversely affected and any amounts payable on the notes may be reduced.

The Underlier Has Recently Transitioned To Tracking A New Fund Underlying Index, Which Differs From The Prior Fund Underlying Index In Important Ways.

Prior to September 19, 2025, the underlier sought to replicate as closely as possible, before fees and expenses, the price and yield performance of the NYSE Arca Gold Miners Index. After market close on September 19, 2025, the underlier’s benchmark index became the MarketVector^TM Global Gold Miners Index. The MarketVector^TM Global Gold Miners Index differs from the NYSE Arca Gold Miners Index in important ways, including use of different market capitalization criteria for inclusion in the index and different weighting schemes, and the composition of the underlier has changed as a result of this transition.

When evaluating the historical performance of the underlier, you should bear in mind that the index tracked by the underlier during the historical period shown in this pricing supplement before market close on September 19, 2025 is different from the index that the underlier tracks currently. The historical performance of the underlier might have been meaningfully different had the underlier tracked the MarketVector^TM Global Gold Miners Index before market close on September 19, 2025.

We cannot predict what effect these changes may have on the performance of the underlier. It is possible that these changes could adversely affect the performance of the underlier and, in turn, your return on the notes.

Risks Relating To Conflicts Of Interest

Our Economic Interests And Those Of Any Dealer Participating In The Offering Are Potentially Adverse To Your Interests.

You should be aware of the following ways in which our economic interests and those of any dealer participating in the distribution of the notes, which we refer to as a “participating dealer,” are potentially adverse to your interests as an investor in the notes. In engaging in certain of the activities described below and as discussed in more detail in the accompanying product supplement, our affiliates, or any participating dealer or its affiliates may take actions that may adversely affect the value of and your return on the notes, and in so doing they will have no obligation to consider your interests as an investor in the notes. Our affiliates, or any participating dealer or its affiliates may realize a profit from these activities even if investors do not receive a favorable investment return on the notes.

The Underlier

The VanEck^® Gold Miners ETF is issued by the VanEck^® ETF Trust, a registered open-end management company.

Index Composition and Maintenance

Index Universe

The index universe includes only common securities and securities with similar characteristics from financial markets that are freely investable for foreign investors and that provide real-time and historical component and currency pricing. Limited partnerships are excluded. Companies from financial markets that are not freely investable for foreign investors or that do not provide real-time and historical component and currency pricing may still be eligible if they have a listing on an eligible exchange and if they meet all the size and liquidity requirements on that exchange. Securities listed on (1) exchanges in Bahrain, China (domestic market), India, Kuwait, Luxembourg, Oman, Qatar, Russia, Saudi Arabia, United Arab Emirates and Vietnam or (2) Paris Euronext Auction, Hamburger Boerse, Boerse Berlin, Oslo Euronext Growth or London Stock Exchange are excluded.

Investable Index Universe

Only companies with a free float (or shares available to foreign investors) of 5% or more for existing index components or 10% or more for new components are eligible for inclusion the Global Gold Miners Index. In addition, stocks that are currently not in the Global Gold Miners Index must meet the following size and liquidity requirements:

For stocks already in the Global Gold Miners Index the following applies:

In case the number of investable stocks drops below the minimum component number, additional companies are flagged eligible by MVIS’s decision until the number of eligible stocks equals the minimum component count.

Only one share line of each company is eligible. In case more than one share line fulfills the above size and liquidity rules, only the largest share line by free float market capitalization is eligible. MVIS can, in exceptional cases (e.g., significantly higher liquidity), decide for a different share line.

In case the free float market capitalization of a non-component share line:

the current component share line will be replaced by the larger one. MVIS can, in exceptional cases (e.g., significantly higher liquidity), decide to keep the current share line instead.

Index Constituent Selection

The Global Gold Miners Index is reviewed and rebalanced on a quarterly basis in March, June, September and December. The target coverage of the Global Gold Miners Index is 90% of the free float market capitalization of the investable universe with at least 25 companies. The constituents of the Global Gold Miners Index are selected using the following procedure:

In addition to the periodic reviews, the Global Gold Miners Index is continually reviewed for corporate events (e.g., mergers, takeovers, spin-offs, delistings and bankruptcies) that affect the index components.

Index Calculation

The value of the Global Gold Miners Index is calculated using the Laspeyres’ formula, with stock prices converted to U.S. dollars:

where (for all stocks (i) in the relevant MVIS Index):

Free Float

The Global Gold Miners Index is free float-adjusted — that is, the number of shares outstanding is reduced to exclude closely held shares (amount larger than 5% of the company’s full market capitalization) from the index calculation. At times, other adjustments are made to the share count to reflect foreign ownership limits or sanctions. These are combined with the block-ownership adjustments into a single factor. To avoid unwanted double counting, either the block-ownership adjustment or the restricted stocks adjustment is applied, whichever produces the higher result. Free float factors are reviewed quarterly.

Index Company-Weighting Cap Factors

Companies in the Global Gold Miners Index are ranked according to their free float market capitalization, as modified by the company-weighting cap factors. The Global Gold Miners Index uses the company-weighting cap factors to ensure diversification to avoid overweighting. The company-weighting cap factors are reviewed quarterly and applied, if necessary. The following weighting scheme applies to the Global Gold Miners Index:

In case the aggregated weight of all index components with less than 50% of their revenue derived from the activities described above exceeds 20%, a weighting cap factor will be applied to ensure the aggregated weight of such index components does not exceed 20%. The excess weight shall be proportionally redistributed among the uncapped index components with more than 50% exposure to such activities within the Small-Weights.

Historical Information

We obtained the closing prices of the underlier in the graph below from Bloomberg Finance L.P., without independent verification.

The following graph sets forth daily closing prices of the underlier for the period from January 2, 2020 to October 3, 2025. The closing price on October 3, 2025 was $77.08. The historical performance of the underlier should not be taken as an indication of its future performance during the term of the notes. When evaluating the historical performance of the underlier provided below, you should bear in mind that the index tracked by the underlier during the historical period shown below before market close on September 19, 2025 is different from the index that the underlier tracks currently. The historical performance of the underlier might have been meaningfully different had the underlier tracked the MarketVector^TM Global Gold Miners Index before market close on September 19, 2025. See “Risk Factors—The Underlier Has Recently Transitioned To Tracking A New Fund Underlying Index, Which Differs From The Prior Fund Underlying Index In Important Ways” in this pricing supplement.

United States Federal Income Tax Considerations

Although there is uncertainty regarding the U.S. federal income tax consequences of an investment in the notes due to the lack of governing authority, in the opinion of our counsel Davis Polk & Wardwell LLP, under current law, and based on current market conditions, it is reasonable to treat a note as a single financial contract that is an “open transaction” for U.S. federal income tax purposes. Assuming this treatment of the notes is respected, the tax consequences are as outlined in the discussion under “United States Federal Income Tax Considerations—Tax Consequences to U.S. Holders—Notes Treated as Open Transactions” in the accompanying product supplement.

Even if the treatment of the notes as “open transactions” is respected, a purchase of a note may be treated as entry into a “constructive ownership transaction,” within the meaning of Section 1260 of the Code. In that case, all or a portion of any long-term capital gain a U.S. investor would otherwise recognize in respect of a note would be recharacterized as ordinary income to the extent such gain exceeded the “net underlying long-term capital gain.” Any long-term capital gain recharacterized as ordinary income under Section 1260 would be treated as accruing at a constant rate over the period the U.S. investor held the notes, and the U.S. investor would be subject to an interest charge in respect of the deemed tax liability on the income treated as accruing in prior tax years. Due to the lack of governing authority there is significant uncertainty as to whether or how these rules will apply to the notes. U.S. investors should read the section entitled “United States Federal Income Tax Considerations—Tax Consequences to U.S. Holders—Notes Treated as Open Transactions—Possible Application of Section 1260 of the Code” in the accompanying product supplement for additional information and consult their tax advisors regarding the potential application of the “constructive ownership” rule.

We do not plan to request a ruling from the Internal Revenue Service (the “IRS”) regarding the treatment of the notes. If the IRS were successful in asserting an alternative treatment of the notes, the tax consequences of the ownership and disposition of the notes, including the timing and character of income recognized by U.S. investors, and the withholding tax consequences to non-U.S. investors, might be materially and adversely affected. For example, under one alternative characterization the notes may be treated as contingent payment debt instruments, which among other things would require U.S. investors to accrue income periodically based on a “comparable yield” and generally would require non-U.S. investors to certify their non-U.S. status on an IRS Form W-8 to avoid a 30% (or a lower treaty rate) U.S. withholding tax. In addition, the U.S. Treasury Department and the IRS have requested comments on various issues regarding the U.S. federal income tax treatment of “prepaid forward contracts” and similar financial instruments and have indicated that such transactions may be the subject of future regulations or other guidance. Furthermore, members of Congress have proposed legislative changes to the tax treatment of derivative contracts. Any legislation, Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the notes, possibly with retroactive effect.

As discussed in the accompanying product supplement, Section 871(m) of the Code and the Treasury regulations thereunder (“Section 871(m)”) generally impose a 30% (or lower treaty rate) withholding tax on “dividend equivalents” paid or deemed paid to non-U.S. investors with respect to certain financial instruments linked to equities that could pay U.S.-source dividends for U.S. federal income tax purposes (“underlying securities”), as defined under the applicable Treasury regulations, or indices that include underlying securities. Section 871(m) generally applies to financial instruments that substantially replicate the economic performance of one or more underlying securities, as determined based on tests set forth in the applicable Treasury regulations. Pursuant to an IRS notice, Section 871(m) will not apply to notes issued before January 1, 2027 that do not have a delta of one with respect to any underlying security. Based on our determination that the notes do not have a delta of one with respect to any underlying security, the securities should not be subject to Section 871(m). Our determination is not binding on the IRS, and the IRS may disagree with this determination. Section 871(m) is complex and its application may depend on a non-U.S. investor’s particular circumstances, including whether the non-U.S. investor enters into other transactions with respect to an underlying security. If withholding is required, we will not be required to pay any additional amounts with respect to the amounts so withheld. Non-U.S. investors should consult their tax advisors regarding the potential application of Section 871(m) to the notes.

Both U.S. and non-U.S. investors considering an investment in the notes should read the discussion under “United States Federal Income Tax Considerations” in the accompanying product supplement and consult their tax advisors regarding all aspects of the U.S. federal income tax consequences of an investment in the notes, including possible alternative treatments, and any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Supplemental Plan of Distribution

BMOCM, our subsidiary, is the agent for the distribution of the notes and will purchase the notes at the original issue price less the underwriting discount specified on the cover page of this pricing supplement. BMOCM may resell the notes to other securities dealers at the original issue price of the notes less a concession not in excess of the underwriting discount. In addition, a fee will be paid to iCapital Markets LLC, an electronic platform in which an affiliate of Goldman Sachs & Co. LLC, who is acting as a dealer in connection with the distribution of the notes, holds an indirect minority equity interest, for services it is providing in connection with this offering.

We expect to hedge our obligations through one or more hedge counterparties (which may be one or more of our affiliates). The agent or another affiliate of ours expects to realize hedging profits projected by its proprietary pricing models to the extent it assumes the risks inherent in hedging our obligations under the notes. If any dealer participating in the distribution of the notes or any of its affiliates conducts hedging activities for us in connection with the notes, that dealer or its affiliate will expect to realize a profit projected by its proprietary pricing models from such hedging activities. Any such projected profit will be in addition to any discount or concession received in connection with the sale of the notes to you.

BMOCM may, but is not obligated to, make a market in the notes. BMOCM will determine any secondary market prices that it is prepared to offer in its sole discretion.

For a period of approximately 3 months following issuance of the notes, the price, if any, at which we or our affiliates would be willing to buy the notes from investors, and the value that BMOCM may also publish for the notes through one or more financial information vendors and which could be indicated for the notes on any brokerage account statements, will reflect a temporary upward adjustment from our estimated value of the notes that would otherwise be determined and applicable at that time. This temporary upward adjustment represents a portion of (a) the hedging profit that we or our affiliates expect to realize over the term of the notes and (b) any underwriting discount and selling concessions paid in connection with this offering. The amount of this temporary upward adjustment will decline to zero on a straight-line basis over the 3 month period.

We may use this pricing supplement in the initial sale of the notes. In addition, BMOCM or another of our affiliates may use this pricing supplement in market-making transactions in any notes after their initial sale. Unless BMOCM or we inform you otherwise in the confirmation of sale, this pricing supplement is being used by BMOCM in a market-making transaction.

See “Supplemental Plan of Distribution” in the accompanying product supplement, “Supplemental Plan of Distribution (Conflicts of Interest) in the accompanying prospectus supplement and “Plan of Distribution (Conflicts of Interest)” in the accompanying prospectus for more information.
