[424B2] MicroSectors Energy 3x Leveraged ETNs Prospectus Supplement

Rhea-AI Filing Summary

Bank of Montreal ("BMO") is offering senior, unsecured Market-Linked Securities that combine an auto-call feature, leveraged upside exposure to the S&P 500® Index (the “Underlier”) and contingent downside protection. The $1,000 face-amount notes price on 30 Jun 2025 and settle 3 Jul 2025, with a scheduled maturity of 6 Jul 2028 (3.0-year maximum tenor).

Automatic call. If on the single call date (6 Jul 2026) the Underlier’s closing level is at or above the starting value of 6,204.95, the notes are redeemed early for 100% of face plus an 8.90% call premium ($1,089 per note). Investors then forfeit any further upside potential.

Maturity payout when not called. • Upside: Ending value > starting value pays face plus 125% of the index gain. • Contingent protection: If the index closes between 75% and 100% of the start level, investors receive face value. • Downside: Below the 75% threshold (4,653.7125), principal is fully exposed to the index loss—investors can lose more than 25% and up to their entire investment.

Key economics. The estimated initial value is $966.36 (96.636% of face), reflecting dealer discount (up to $25.75), structuring and hedging costs. Proceeds to BMO are $974.25 per note. Wells Fargo Securities acts as principal agent; BMOCM is calculation agent.

Risk profile. The notes: (1) pay no periodic interest or dividends, (2) are subject to BMO’s credit risk, (3) are unlisted with no required secondary market, (4) may be redeemed early, creating reinvestment risk, and (5) carry complex tax treatment. Investors should read “Selected Risk Considerations” and underlying supplements before investing.

Investment thesis. The structure targets investors who are moderately bullish on the S&P 500 over a one-to-three-year horizon, value a 25% buffer against moderate declines, and are willing to cap upside at 8.90% if the index rallies quickly. It is not suitable for investors seeking full principal protection, liquidity, or periodic income.

Positive

• 8.90% fixed call premium payable after only one year if the S&P 500 is flat or higher, providing an above-market short-term return.
• 125% upside participation for gains between years one and three allows leveraged exposure without margin requirements.
• 25% contingent protection means principal is returned in full at maturity if the index drop is limited to 25% or less.
• Senior unsecured debt of an A/A+ rated issuer, offering higher credit quality than many structured-note peers.

Negative

• Full downside beyond –25%; investors could lose their entire investment if the S&P 500 falls more than 75%.
• Issuer credit risk; all payments depend on Bank of Montreal’s ability to pay, with no FDIC/CDIC insurance.
• Liquidity constraints; the notes are unlisted and any secondary market is at the dealer’s discretion with likely substantial bid–ask spreads.
• No periodic income; holders forgo dividends on the underlying equities and receive no coupons.
• Estimated initial value of 96.636% indicates roughly 3.4% in embedded fees, immediately lowering economic value.

Insights

Structured-Products Analyst

TL;DR 3-year S&P 500 note offers 8.9% one-year call, 125% upside thereafter, 25% buffer; high credit/market risk and limited liquidity.

The pricing supplement reveals a fairly typical auto-call structure. The 8.9% call premium equals roughly a 9% simple annualised return if the index is flat or up modestly in year 1, attractive versus short-dated IG corporates. After the call window, investors keep 125% of gains, which can materially outperform the index if a rally occurs late in the term. However, the 25% contingent buffer is thin compared with historical S&P 500 drawdowns; a move below –25% at maturity converts to linear losses, exposing holders to potentially total loss.

The $966.36 estimated value implies ~3.4% in embedded costs—slightly tighter than peer deals but still meaningful. Secondary liquidity is expected to be dealer-driven with bid-offer spreads reflecting these costs. From a portfolio perspective, the note can complement equity exposure but should be sized conservatively given binary outcomes and issuer credit exposure (BMO senior debt rated A/A+). Overall impact: neutral-to-slightly positive for investors who understand the trade-offs.

Credit & Risk Specialist

TL;DR Unsecured obligation of BMO; default or severe index decline could wipe out capital—creditworthiness and market timing are critical.

Because payments hinge on BMO’s ability to perform, any deterioration in the bank’s credit spreads will pressure secondary values. The single call observation concentrates risk: a brief dip at year-one forfeits the premium, while a late-cycle sell-off below the 75% threshold imposes full downside. Lack of interim coupons increases carry risk relative to conventional bonds. From a risk-adjusted standpoint, investors are exchanging 100% principal risk for leveraged equity upside with capped early return—suitable only for sophisticated accounts capable of absorbing potential 100% loss.

Principal at Risk Securities Linked to the S&P 500^® Index due July 6, 2028

n Linked to the S&P 500^® Index (the “Underlier”)

n Unlike ordinary debt securities, the securities do not pay interest or repay a fixed amount of principal at maturity and are subject to potential automatic call upon the terms described below. Whether the securities are automatically called for a fixed call premium or, if not automatically called, the maturity payment amount, will depend, in each case, on the performance of the Underlier.

n Automatic Call. If the closing value of the Underlier on the call date occurring approximately one year after issuance is greater than or equal to the starting value, the securities will be automatically called for the face amount plus a call premium of 8.90% of the face amount

n Maturity Payment Amount. If the securities are not automatically called, you will receive a maturity payment amount that could be greater than, equal to or less than the face amount depending on the ending value of the Underlier as follows:

n If the ending value is greater than the starting value, you will receive the face amount plus a positive return equal to 125% of the percentage increase in the value of the Underlier from the starting value

n If the ending value is less than the starting value but not by more than 25%, you will receive the face amount

n If the ending value is less than the starting value by more than 25%, you will have full downside exposure to the decrease in the value of the Underlier from the starting value, and you will lose more than 25%, and possibly all, of the face amount of your securities

n Investors may lose a significant portion or all of the face amount

n If the securities are automatically called, the positive return on the securities will be limited to the call premium, and you will not participate in any appreciation of the Underlier, which may be significant. If the securities are automatically called, you will no longer have the opportunity to participate in any appreciation of the Underlier at the upside participation rate

n All payments on the securities are subject to the credit risk of Bank of Montreal, and you will have no ability to pursue any securities included in the Underlier for payment; if Bank of Montreal defaults on its obligations, you could lose some or all of your investment

n No periodic interest payments or dividends

n No exchange listing; designed to be held to maturity or automatic call

Estimated Value of the Securities

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

· a fixed-income debt component with the same tenor as the securities, valued using our internal funding rate for structured notes; and

· one or more derivative transactions relating to the economic terms of the securities.

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 securities is based on market conditions at the time it is calculated.

Investor Considerations

The securities are not appropriate for all investors. The securities may be an appropriate investment for investors who:

§ seek a fixed return equal to the call premium if the securities are automatically called on the call date;

§ understand that the securities may be automatically called prior to the stated maturity and that the term of the securities may be reduced;

§ seek 125% leveraged exposure to the upside performance of the Underlier if the securities are not automatically called and the ending value is greater than the starting value;

§ desire payment of the face amount at maturity if the securities are not automatically called so long as the ending value is not less than the starting value by more than 25%;

§ are willing to accept the risk that, if the securities are not automatically called and the ending value is less than the starting value by more than 25%, they will be fully exposed to the decrease in the value of the Underlier from the starting value, and will lose more than 25%, and possibly all, of the face amount per security at maturity;

§ are willing to forgo interest payments on the securities and dividends on the securities included in the Underlier; and

§ are willing to hold the securities until maturity or automatic call.

The securities may not be an appropriate investment for investors who:

§ seek a liquid investment or are unable or unwilling to hold the securities to maturity or automatic call;

§ seek a security with a fixed term;

§ are unwilling to accept the risk that the securities may not be automatically called and the ending value of the Underlier may decrease from the starting value by more than 25%;

§ seek full return of the face amount of the securities at stated maturity;

§ are unwilling to purchase securities with an estimated value as of the pricing date that is lower than the original offering price, as set forth on the cover page;

§ seek current income over the term of the securities;

§ are unwilling to accept the risk of exposure to the Underlier;

§ seek exposure to the Underlier but are unwilling to accept the risk/return trade-offs inherent in the maturity payment amount for the securities;

§ are unwilling to accept the credit risk of Bank of Montreal to obtain exposure to the Underlier generally, or to the exposure to the Underlier that the securities provide specifically; or

§ prefer the lower risk of fixed income investments with comparable maturities issued by companies with comparable credit ratings.

The considerations identified above are not exhaustive. Whether or not the securities are an appropriate investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisors have carefully considered the appropriateness of an investment in the securities in light of your particular circumstances. You should also review carefully the sections titled “Selected Risk Considerations” herein and “Risk Factors” in the accompanying product supplement for risks related to an investment in the securities.

Selected Risk Considerations

The securities have complex features and investing in the securities will involve risks not associated with an investment in conventional debt securities. Some of the risks that apply to an investment in the securities are summarized below, but we urge you to read the more detailed explanation of the risks relating to the securities 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 securities in light of your particular circumstances.

Risks Relating To The Securities Generally

If The Securities Are Not Automatically Called And The Ending Value Is Less Than The Threshold Value, You Will Lose More Than 25%, And Possibly All, Of The Face Amount Of Your Securities At Maturity.

If the securities are not automatically called, we will not repay you a fixed amount on the securities on the stated maturity date. The maturity payment amount will depend on the direction of and percentage change in the ending value relative to the starting value and the other terms of the securities. Because the value of the Underlier will be subject to market fluctuations, the maturity payment amount may be more or less, and possibly significantly less, than the face amount of your securities.

If the securities are not automatically called and the ending value is less than the threshold value, the maturity payment amount will be less than the face amount and you will have full downside exposure to the decrease in the value of the Underlier from the starting value. The threshold value is 75% of the starting value. For example, if the Underlier has declined by 25.1% from the starting value to the ending value, you will not receive any benefit of the contingent downside feature and you will lose 25.1% of the face amount per security. As a result, you will not receive any protection if the ending value is less than the threshold value and you will lose more than 25%, and possibly all, of the face amount per security at maturity. This is the case even if the value of the Underlier is greater than or equal to the starting value or the threshold value at certain times during the term of the securities.

If the securities are not automatically called, even if the ending value is greater than the starting value, the maturity payment amount may only be slightly greater than the face amount, and your yield on the securities may be less than the yield you would earn if you bought a traditional interest-bearing debt security of Bank of Montreal or another issuer with a similar credit rating with the same stated maturity date.

If The Securities Are Automatically Called, Your Return Will Be Limited To The Call Premium.

If the securities are automatically called, the positive return on the securities will be limited to the call premium, and you will not participate in any appreciation of the Underlier, which may be significant. Accordingly, if the securities are automatically called, the return on the securities may be less than the return on a direct investment in the securities included in the Underlier. If the securities are automatically called, you will no longer have the opportunity to participate in any appreciation of the Underlier at the upside participation rate.

You Will Be Subject To Reinvestment Risk.

If your securities are automatically called, the term of the securities may be reduced. There is no guarantee that you would be able to reinvest the proceeds from an investment in the securities at a comparable return for a similar level of risk in the event the securities are automatically called prior to maturity.

The Securities Do Not Pay Interest.

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

The Securities Are Subject To Credit Risk.

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

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

There is no direct legal authority regarding the proper U.S. federal income tax treatment of the securities and we do not plan to request a ruling from the Internal Revenue Service (the “IRS”) with respect to the securities. Consequently, significant aspects of the tax treatment of the securities 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 securities, the tax consequences of the ownership and disposition of the securities, 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. Moreover, future legislation, Treasury regulations or IRS guidance could adversely affect the U.S. federal income tax treatment of the securities, possibly retroactively.

PRS-8

Market Linked Securities—Auto-Callable with Leveraged Upside Participation and Contingent Downside

Principal at Risk Securities Linked to the S&P 500^® Index due July 6, 2028

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 securities, as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

The Stated Maturity Date May Be Postponed If The Final Calculation Day Is Postponed.

The final calculation day will be postponed if the originally scheduled final calculation day is not a trading day or if the calculation agent determines that a market disruption event has occurred or is continuing on that day. If such a postponement occurs, the stated maturity date may be postponed. For additional information, see “General Terms of the Securities—Consequences of a Market Disruption Event; Postponement of a Calculation Day—Securities Linked to a Single Market Measure” and “—Payment Dates” in the accompanying product supplement.

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

The Estimated Value Of The Securities On The Pricing Date, Based On Our Proprietary Pricing Models, Will Be Less Than The Original Offering Price.

Our initial estimated value of the securities is only an estimate, and is based on a number of factors. The original offering price of the securities may exceed our initial estimated value, because costs associated with offering, structuring and hedging the securities are included in the original offering price, but are not included in the estimated value. These costs will include any agent discount and selling concessions and the cost of hedging our obligations under the securities through one or more hedge counterparties (which may be one or more of our affiliates or an agent or its 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 Securities Are Not Determined By Reference To The Credit Spreads For Our Conventional Fixed-Rate Debt.

To determine the terms of the securities, 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 securities are less favorable to you than if we had used a higher funding rate.

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

Our initial estimated value of the securities 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 the agent, its affiliates or other market participants, could provide values for the securities that are greater than or less than our initial estimated value. In addition, market conditions and other relevant factors after the pricing date are expected to change, possibly rapidly, and our assumptions may prove to be incorrect. After the pricing date, the value of the securities 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 WFS or its affiliates or any other party (including us or our affiliates) would be willing to purchase the securities from you in any secondary market transactions. Our initial estimated value does not represent a minimum price at which WFS or any other party (including us or our affiliates) would be willing to buy your securities in any secondary market at any time.

WFS has advised us that if it, WFA or any of their affiliates makes a secondary market in the securities at any time, the secondary market price offered by it, WFA or any of their affiliates will be affected by changes in market conditions and other factors described in the next risk factor. WFS has advised us that if it, WFA or any of their affiliates makes a secondary market in the securities at any time up to the issue date or during the 3-month period following the issue date, the secondary market price offered by it, WFA or any of its affiliates will be increased by an amount reflecting a portion of the costs associated with selling, structuring and hedging the securities that are included in their original offering price. Because this portion of the costs is not fully deducted upon issuance, WFS has advised us that any secondary market price it, WFA or any of their affiliates offers during this period will be higher than it otherwise would be after this period, as any secondary market price offered after this period will reflect the full deduction of the costs as described above. WFS has advised us that the amount of this increase in the secondary market price will decline steadily to zero over this 3-month period. WFS has advised us that, if you hold the securities through an account with WFS, WFA or any of their affiliates, WFS expects that this increase will also be reflected in the value indicated for the securities on your brokerage account statement. If you hold your securities through an account at a broker-dealer other than WFS, WFA or any of their affiliates, the value of the securities on your brokerage account statement may be different than if you held your securities at WFS, WFA or any of their affiliates.

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

The value of the securities 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 securities: performance of the Underlier; interest rates; volatility of the Underlier; time remaining to maturity; and dividend yields on the securities included in the Underlier. When we refer to the “value” of your securities, we mean the value you could receive for your securities 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 securities will be affected by actual or anticipated changes in our creditworthiness. The value of the securities will also be limited by the automatic call feature because if the securities are automatically called, your return will be limited to the call premium, and you will not receive the potentially higher payment that may have been paid if you had held the securities until the stated maturity date. 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 securities 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 securities, changes in the value of the Underlier may not result in a comparable change in the value of the securities.

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

The securities will not be listed or displayed on any securities exchange. Although the agent and/or its affiliates may purchase the securities from holders, they are not obligated to do so and are not required to make a market for the securities. 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 securities, the price at which you may be able to sell your securities is likely to depend on the price, if any, at which the agent is willing to buy your securities.

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 securities prior to stated maturity. This may affect the price you receive upon such sale. Consequently, you should be willing to hold the securities to stated maturity.

Risks Relating To The Underlier

Whether The Securities Will Be Automatically Called And The Maturity Payment Amount Will Depend Upon The Performance Of The Underlier And Therefore The Securities Are Subject To The Following Risks, Each As Discussed In More Detail In The Accompanying Product Supplement.

· Investing In The Securities Is Not The Same As Investing In The Underlier. Investing in the securities is not equivalent to investing in the Underlier. As an investor in the securities, your return will not reflect the return you would realize if you actually owned and held the securities included in the Underlier for a period similar to the term of the securities because you will not receive any dividend payments, distributions or any other payments paid on those securities. As a holder of the securities, you will not have any voting rights or any other rights that holders of the securities included in the Underlier would have.

· Historical Values Of The Underlier Should Not Be Taken As An Indication Of The Future Performance Of The Underlier During The Term Of The Securities.

· Changes That Affect The Underlier May Adversely Affect The Value Of The Securities, Whether The Securities Will Be Automatically Called And The Maturity Payment Amount.

· We Cannot Control Actions By Any Of The Unaffiliated Companies Whose Securities Are Included In The Underlier.

· We And Our Affiliates Have No Affiliation With The Underlier Sponsor And Have Not Independently Verified Its Public Disclosure Of Information.

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 securities, which we refer to as a “participating dealer,” are potentially adverse to your interests as an investor in the securities. 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 securities, and in so doing they will have no obligation to consider your interests as an investor in the securities. 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 securities.

· The calculation agent is our affiliate and may be required to make discretionary judgments that affect the return you receive on the securities. BMOCM, which is our affiliate, will be the calculation agent for the securities. As calculation agent, BMOCM will determine any values of the Underlier and make any other determinations necessary to calculate any payments on the securities. In making these determinations, BMOCM may be required to make discretionary judgments that may adversely affect any payments on the securities. See the sections entitled “General Terms of the Securities— Certain Terms for Securities Linked to an Index—Market Disruption Events,” “—Adjustments to an Index” and “—Discontinuance of an Index” in the accompanying product supplement. In making these discretionary judgments, the fact that BMOCM is our affiliate may cause it to have economic interests that are adverse to your interests as an investor in the securities, and BMOCM’s determinations as calculation agent may adversely affect your return on the securities.

· The estimated value of the securities was calculated by us and is therefore not an independent third-party valuation.

· Research reports by our affiliates or any participating dealer or its affiliates may be inconsistent with an investment in the securities and may adversely affect the value of the Underlier.

· Business activities of our affiliates or any participating dealer or its affiliates with the companies whose securities are included in the Underlier may adversely affect the value of the Underlier.

· Hedging activities by our affiliates or any participating dealer or its affiliates may adversely affect the value of the Underlier.

· Trading activities by our affiliates or any participating dealer or its affiliates may adversely affect the value of the Underlier.

· A participating dealer or its affiliates may realize hedging profits projected by its proprietary pricing models in addition to any selling concession and/or other fee, creating a further incentive for the participating dealer to sell the securities to you.

Hypothetical Examples and Returns

The payout profile, return table and examples below illustrate hypothetical payments upon an automatic call or at stated maturity for a $1,000 face amount security on a hypothetical offering of securities under various scenarios, with the assumptions set forth in the table below. The terms used for purposes of these hypothetical examples do not represent the actual starting value or threshold value. The hypothetical starting value of 100.00 has been chosen for illustrative purposes only and does not represent the actual starting value. The actual starting value and threshold value are set forth under “Terms of the Securities” above. For actual historical data of the Underlier, see the historical information set forth herein. The payout profile, return table and examples below assume that an investor purchases the securities for $1,000 per security. These examples are for purposes of illustration only and the values used in the examples may have been rounded for ease of analysis. The actual amount you receive at stated maturity or upon automatic call, and the resulting pre-tax total rate of return will depend on the actual terms of the securities.

Call Premium:	8.90% of the face amount
Upside Participation Rate:	125%
Hypothetical Starting Value:	100.00
Hypothetical Threshold Value:	75.00 (75% of the hypothetical starting value)

Hypothetical Examples Of Payment Upon An Automatic Call Or At Stated Maturity

Example 1. The closing value of the Underlier on the call date is greater than the starting value, and the securities are automatically called on the call date:

	The Underlier
Hypothetical starting value:	100.00
Hypothetical closing value on call date:	125.00

Because the hypothetical closing value of the Underlier on the call date is greater than the hypothetical starting value, the securities are automatically called on the call date and you will receive on the call settlement date the face amount of your securities plus a call premium of 8.90% of the face amount. Even though the Underlier appreciated by 25.00% from its starting value to its closing value on the call date in this example, your return is limited to the call premium of 8.90%.

On the call settlement date, you would receive $1,089.00 per security.

Example 2. The securities are not automatically called. The maturity payment amount is greater than the face amount:

	The Underlier
Hypothetical starting value:	100.00
Hypothetical closing value on the call date:	80.00
Hypothetical ending value:	110.00
Hypothetical threshold value:	75.00
Hypothetical underlier return:	10.00%

Because the hypothetical closing value of the Underlier on the call date is less than the hypothetical starting value, the securities are not automatically called. Because the hypothetical ending value is greater than the hypothetical starting value, the maturity payment amount per security would be equal to:

$1,000 + ($1,000 × underlier return × upside participation rate)

$1,000 + ($1,000 × 10.00% × 125.00%)

= $1,125.00

On the stated maturity date, you would receive $1,125.00 per security.

Example 3. The securities are not automatically called. Maturity payment amount is equal to the face amount:

	The Underlier
Hypothetical starting value:	100.00
Hypothetical closing value on the call date:	80.00
Hypothetical ending value:	95.00
Hypothetical threshold value:	75.00
Hypothetical underlier return:	-5.00%

Because the hypothetical closing value of the Underlier on the call date is less than the hypothetical starting value, the securities are not automatically called. Because the hypothetical ending value is less than the hypothetical starting value, but not by more than 25%, you would not lose any of the face amount of your securities.

On the stated maturity date, you would receive $1,000.00 per security.

Example 4. The securities are not automatically called. Maturity payment amount is less than the face amount:

Hypothetical closing value on the call date:	80.00
Hypothetical ending value:	50.00
Hypothetical threshold value:	75.00
Hypothetical underlier return:	-50.00%

Because the hypothetical closing value of the Underlier on the call date is less than the hypothetical starting value, the securities are not automatically called. Because the hypothetical ending value is less than the hypothetical starting value by more than 25%, you would lose a portion of the face amount of your securities and receive a maturity payment amount per security equal to:

$1,000 + ($1,000 × underlier return)

$1,000 + ($1,000 × -50.00%)

= $500.00

On the stated maturity date, you would receive $500.00 per security.

United States Federal Income Tax Considerations

Although there is uncertainty regarding the U.S. federal income tax consequences of an investment in the securities 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 security as a single financial contract that is an “open transaction” for U.S. federal income tax purposes. Assuming this treatment of the securities is respected, the tax consequences are as outlined in the discussion under “United States Federal Income Tax Considerations—Tax Consequences to U.S. Holders— Securities Treated as Open Transactions” in the accompanying product supplement.

We do not plan to request a ruling from the Internal Revenue Service (the “IRS”) regarding the treatment of the securities. If the IRS were successful in asserting an alternative treatment of the securities, the tax consequences of the ownership and disposition of the securities, 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 securities may be treated as contingent payment debt instruments, which 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 securities, 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 securities 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 securities 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 securities.

Both U.S. and non-U.S. investors considering an investment in the securities 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 and estate tax consequences of an investment in the securities, including possible alternative treatments, and any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.
