Jefferies (JEF) prices buffered autocallable notes tied to GDX and S&P 500

Q: What is Jefferies (JEF) offering in this 424B2 pricing supplement?

Jefferies is offering Senior Autocallable Contingent Coupon Buffered Notes due January 2, 2031 with an aggregate principal amount of $772,000 , linked to the worst-performing of the VanEck Gold Miners ETF (GDX) and the S&P 500 Index (SPX).

Q: How do the contingent coupon payments work on the Jefferies (JEF) notes?

On each quarterly observation date, if the worst-performing underlying is at or above its coupon barrier (70% of its initial value), investors receive a $25.63 contingent coupon per $1,000 note on the related payment date. If the worst-performing underlying is below its coupon barrier, no coupon is paid for that period.

Q: When can the Jefferies autocallable notes be redeemed early?

The notes are autocallable quarterly starting on December 29, 2026 . If, on any call observation date, the worst-performing underlying is at or above its call value (100% of its initial level), the notes are automatically called and investors receive the stated principal amount plus any due contingent coupon , with no further payments.

Q: What happens at maturity if the Jefferies notes are not called?

If the notes are not called, at maturity on January 2, 2031 investors receive the $1,000 principal per note if the final value of the worst-performing underlying is at or above its threshold value (80% of its initial level). If it is below the threshold, repayment is reduced 1% for each 1% decline below the threshold, with up to 80% of principal potentially lost. The final contingent coupon is also paid if the worst-performing underlying is at or above its coupon barrier on the final observation date.

Q: What are the key initial levels and barriers for GDX and the S&P 500 in this Jefferies note?

The initial values are $85.85 for GDX and 6,905.74 for the S&P 500 Index. The coupon barriers are $60.10 for GDX and 4,834.02 for the S&P 500 (70% of their initial values). The threshold values are $68.68 for GDX and 5,524.59 for the S&P 500 (80% of their initial values).

Q: What is the estimated value and pricing of the Jefferies (JEF) structured notes?

Each note has an issue price of $1,000 . Jefferies estimates the value on the pricing date at $933.60 per note, reflecting issuance, structuring and hedging costs. The public offering price is 100% of principal, underwriting discounts and commissions are 3.50% , and proceeds to Jefferies before expenses are 96.50% of principal.

Q: What are the main risks of investing in these Jefferies autocallable buffered notes?

Key risks include: potential loss of up to 80% of principal if the worst-performing underlying finishes below its threshold value; the possibility of receiving no contingent coupons if the worst-performing underlying stays below its coupon barrier; exposure only to the worst-performing of GDX and the S&P 500; credit risk of Jefferies as unsecured issuer; limited or no secondary market; and structural risks tied to the gold miners sector, equity market volatility, foreign markets and complex tax treatment.

THE NOTES

The Notes are senior unsecured obligations of Jefferies Financial Group Inc. The Aggregate Principal Amount of the Notes is $772,000. The Notes will mature on January 2, 2031. The Notes have the terms described in the accompanying product supplement, prospectus supplement and prospectus, as supplemented or modified by this pricing supplement. The Notes will pay a Contingent Coupon Payment of $25.63 on the applicable Coupon Payment Date if the Observation Value of the Worst-Performing Underlying on the applicable quarterly Coupon Observation Date is greater than or equal to its Coupon Barrier. The Notes will be automatically called if the Observation Value of the Worst-Performing Underlying on any Call Observation Date (beginning approximately one year after the Pricing Date) is equal to or greater than its Call Value. If your Notes are called, you will receive the Call Payment on the applicable Call Payment Date, and no further amounts will be payable on the Notes. If your Notes are not called, at maturity, if the Final Value of the Worst-Performing Underlying is greater than or equal to its Threshold Value, you will receive the Stated Principal Amount; otherwise, your Notes are subject to 1-to-1 downside exposure to decreases in the Worst-Performing Underlying from its Threshold Value, with up to 80% of the Stated Principal Amount at risk. At maturity you will also receive the final Contingent Coupon Payment if the Observation Value of the Worst-Performing Underlying on the final Coupon Observation Date is greater than or equal to its Coupon Barrier. For more information on the Coupon Feature, the Call Feature and the Payment at Maturity please see “Summary of Terms” on the cover page of this pricing supplement. All payments on the Notes are subject to our credit risk. The Notes are issued as part of our Series A Global Medium-Term Notes program.

The Stated Principal Amount of each Note is $1,000. The Issue Price will equal 100% of the Stated Principal Amount per Note. This price includes costs associated with issuing, selling, structuring and hedging the Notes, which are borne by you, and, consequently, the estimated value of the Notes on the Pricing Date is less than the Issue Price. We estimate that the value of each Note on the Pricing Date is $933.60 per Note.

If any Coupon Payment Date, Call Payment Date or the Maturity Date occurs on a day that is not a Business Day, then the payment owed on such date will be postponed until the next succeeding Business Day, and no interest will accrue as a result of such delay.

Capitalized terms used but not defined in this pricing supplement have the meanings set forth in the accompanying product supplement, prospectus supplement or prospectus, as applicable. If the terms described herein are inconsistent with those described in the accompanying product supplement, prospectus supplement or prospectus, the terms described herein shall control.

Valuation of the Notes

Jefferies LLC calculated the estimated value of the Notes set forth on the cover page of this pricing supplement based on its proprietary pricing models at that time. Jefferies LLC’s proprietary pricing models generated an estimated value for the Notes by estimating the value of a hypothetical package of financial instruments that would replicate the payout on the Notes, which consists of a fixed-income bond (the “bond component”) and one or more derivative instruments underlying the economic terms of the Notes (the “derivative component”). In calculating the estimated value of the derivative component, Jefferies LLC estimated future cash flows based on a proprietary derivative-pricing model that is in turn based on various inputs, including the factors described under “Risk Factors—The estimated value of the Notes was determined for us by our subsidiary using proprietary pricing models” below. These inputs may be market-observable or may be based on assumptions made by Jefferies LLC in its discretionary judgment. Estimated cash flows on the bond and derivative components were discounted using a discount rate based on our internal funding rate.

The estimated value of the Notes is a function of the terms of the Notes and the inputs to Jefferies LLC’s proprietary pricing models.

Since the estimated value of the Notes is a function of the underlying assumptions and construction of Jefferies LLC’s proprietary derivative-pricing model, modification to this model will impact the estimated value calculation. Jefferies LLC’s proprietary models are subject to ongoing review and modification, and Jefferies LLC may change them at any time and

PS-2

Table of Contents

for a variety of reasons. In the event of a model change, prior descriptions of the model and computations based on the older model will be superseded, and calculations of estimated value under the new model may differ significantly from those under the older model. Further, model changes may cause a larger impact on the estimated value of a note with a particular return formula than on a similar note with a different return formula. For example, to the extent a return formula contains leverage, model changes may cause a larger impact on the estimated value of that note than on a similar note without such leverage.

For an initial period following the issuance of the Notes (the “Temporary Adjustment Period”), the value that will be indicated for the Notes on any brokerage account statements prepared by Jefferies LLC or its affiliates (which value Jefferies LLC may also publish through one or more financial information vendors) will reflect a temporary upward adjustment from the price or value that would otherwise be determined. This temporary upward adjustment represents amounts which may include, but are not limited to, profits, fees, underwriting discounts and commissions and hedging and other costs expected to be paid or realized by Jefferies LLC or its affiliates, or other unaffiliated brokers or dealers, over the term of the Notes. The amount of this temporary upward adjustment will decline to zero on a straight-line basis over the Temporary Adjustment Period.

The relationship between the estimated value on the Pricing Date and the secondary market price of the Notes

The price at which Jefferies LLC purchases the Notes in the secondary market, absent changes in market conditions, including those related to interest rates and the Underlyings, may vary from, and be lower than, the estimated value on the Pricing Date, because the secondary market price takes into account our secondary market credit spread as well as the bid-offer spread that Jefferies LLC would charge in a secondary market transaction of this type, the costs of unwinding the related hedging transactions and other factors.

Jefferies LLC may, but is not obligated to, make a market in the Notes and, if it once chooses to make a market, may cease doing so at any time.

HOW THE NOTES WORK

Coupon Feature and Call Feature

The following examples illustrate the Coupon Feature and Call Feature over a range of hypothetical Observation Values of the Worst-Performing Underlying. The examples below are for purposes of illustration only and do not take into account any tax consequences from investing in the Notes. Payments on the Notes will depend on the actual Observation Values of the Worst-Performing Underlying on the Coupon Observation Dates and Call Observation Dates. For recent historical performance of the Underlyings, please see “The Underlyings” section below. The Observation Values and Final Value of each Underlying will not include any income generated by dividends paid on the Underlying or the stocks included in such Underlying, which you would otherwise be entitled to receive if you invested in those securities directly. In addition, all payments on the Notes are subject to our credit risk.

Example 1. The Observation Value of the Worst-Performing Underlying on the first Coupon Observation Date is below its Coupon Barrier. Therefore no Contingent Coupon Payment will be paid on the applicable Coupon Payment Date, even if the Observation Value of each other Underlying is greater than its Coupon Barrier on the first Coupon Observation Date.

Example 2. The Observation Value of the Worst-Performing Underlying on the fourth Coupon Observation Date (which is also the first Call Observation Date) is below its Call Value but greater than or equal to its Coupon Barrier. Therefore the Notes will not be called but a Contingent Coupon Payment will be paid on the applicable Coupon Payment Date.

Example 3. The Observation Value of the Worst-Performing Underlying on the fourth Coupon Observation Date (which is also the first Call Observation Date) is greater than or equal to its Call Value and Coupon Barrier. Therefore the Notes will be called and the Call Payment will be paid on the applicable Call Payment Date. The Notes will no longer be outstanding and no further amounts will be payable on the Notes.

Payment at Maturity

The table below assumes the Notes have not been called and presents examples of hypothetical Payments at Maturity on the Notes over a range of hypothetical Final Values of the Worst-Performing Underlying. The examples below are for purposes of illustration only and do not take into account any tax consequences from investing in the Notes. The actual Payment at Maturity will depend on the actual Final Value of the Worst-Performing Underlying determined on the Valuation Date.

The table below is based on the following terms:

	Stated Principal Amount:		$1,000 per Note.
	Hypothetical Initial Value of the Worst-Performing Underlying:		100
	Hypothetical Coupon Barrier of the Worst-Performing Underlying:		70
	Hypothetical Threshold Value of the Worst-Performing Underlying:		80
	Contingent Coupon Payment:		$25.63 per Note

Final Value of the Worst- Performing Underlying	Payment at Maturity per Note	Return on the Notes
0.00	$200.00	-80.000%
50.00	$700.00	-30.000%
69.99	$899.90	-10.010%

RISK FACTORS

In addition to the other information contained and incorporated by reference in this pricing supplement and the accompanying product supplement, prospectus and prospectus supplement, including the section entitled “Risk Factors” in our Annual Report on Form 10‑K, you should consider carefully the following factors before deciding to purchase the Notes.

Structure-related Risks

You may lose a significant portion of your investment.

If the Final Value of the Worst-Performing Underlying is less than its Threshold Value, you will receive for each Note that you hold a Payment at Maturity that is less than the Stated Principal Amount of each Note. In this case investors will lose 1% of the Stated Principal Amount for every 1% decline in the Final Value below the Threshold Value. Investors may lose up to 80% of the Stated Principal Amount of the Notes.

Your investment return is limited to the return represented by the Contingent Coupon Payments, if any.

Your investment return will be limited to the return represented by the Contingent Coupon Payments, if any, paid over the term of the Notes. You will not receive a payment on the Notes greater than the Stated Principal Amount plus any Contingent Coupon Payments, regardless of the appreciation of the Underlyings. In contrast, a direct investment in the Underlyings (or any securities, commodities or other assets represented by the Underlyings) would allow you to receive the full benefit of any appreciation in the value of the Underlyings (or those underlying assets).

You may not receive any Contingent Coupon Payments.

You will not necessarily receive any Contingent Coupon Payments on the Notes. If the Observation Value of the Worst-Performing Underlying is less than its Coupon Barrier on each Coupon Observation Date, you will not receive any Contingent Coupon Payments over the term of the Notes. In this case, you will not receive a positive return on the Notes.

If the Notes are called you will be subject to reinvestment risk.

If the Notes are called, the term of the Notes will be short. In such a case, your ability to receive any Contingent Coupon Payments over the term of the Notes will be limited. There is no guarantee that you would be able to reinvest the proceeds from an investment in the Notes at a comparable return for a similar level of risk in the event the Notes are called prior to maturity.

The Notes are subject to the risks of each Underlying, not a basket composed of the Underlyings, and will be negatively affected if the Observation Value or Final Value of any Underlying decreases below its Coupon Barrier, Call Value or Threshold Value on the applicable Coupon Observation Date, Call Observation Date or Valuation Date, even if the Observation Value or Final Value of the other Underlyings do not.

The Notes are linked to the worst-performing of the Underlyings and you are subject to the risks associated with each Underlying. The Notes are not linked to a basket composed of the Underlyings, where the depreciation in the value of one Underlying could be offset to some extent by the appreciation in the value of the other Underlying. The individual performance of each Underlying will not be combined, and the depreciation in the value of one Underlying will not be offset by any appreciation in the value of the other Underlying. For example, even if the Observation Value of an Underlying is at or above its Coupon Barrier, you will not receive a Contingent Coupon Payment on the applicable Coupon Payment Date if the Observation Value of the Worst-Performing Underlying is below its Coupon Barrier. Similarly, if the Final Value of an Underlying is at or above its Threshold Value, you will lose a portion of your principal if the Final Value of the Worst-Performing Underlying is below its Threshold Value.

Payments on the Notes is not linked to the value of the Underlyings at any time other than the Coupon Observation Dates, Call Observation Dates or Valuation Date.

The Observation Value of each Underlying will be based on its Index Closing Value or ETF Closing Price on the applicable Coupon Observation Date or Call Observation Date and the Final Value of each Underlying will be based on its Index Closing Value or ETF Closing Price on the Valuation Date (in each case subject to postponement for non-Index Business Days or non-Trading Days and Certain Market Disruption Events as described in the accompanying product supplement). Even if the value of the Worst-Performing Underlying is always greater than its Coupon Barrier prior to a Coupon Observation Date, you will not receive a Contingent Coupon Payment on the applicable Coupon Payment Date if the Observation Value of the Worst-Performing Underlying is below its Coupon Barrier on the Coupon Observation Date. Furthermore, even if the value of the Worst-Performing Underlying appreciates prior to the Valuation Date but then drops below its Threshold Value on the Valuation Date, the Payment at Maturity will be less, and may be significantly less, than it would have been had the Payment at Maturity been linked to the value of the Worst-Performing Underlying prior to such

Table of Contents

drop. Although the actual value of an Underlying on the Maturity Date or at other times during the term of the Notes may be higher than its Observation Values or Final Value, payments on the Notes will be based solely on the Observation Values and Final Values of the Underlyings.

You will not benefit in any way from the performance of the better performing Underlying.

The return on the Notes will depend solely on the performance of the Worst-Performing Underlying, and you will not benefit in any way from the performance of the better performing Underlying. The Notes may underperform a similar investment in each of the Underlyings or a similar alternative investment linked to a basket composed of the Underlyings. In either such case, the performance of the better performing Underlying would be blended with the performance of the Worst-Performing Underlying, resulting in a potentially better return than what you would receive on the Notes.

The Notes are subject to our credit risk, and any actual or anticipated changes to our credit ratings or credit spreads may adversely affect the market value of the Notes.

You are dependent on our ability to pay all amounts due on the Notes and therefore you are subject to our credit risk. If we default on our obligations under the Notes, your investment would be at risk and you could lose some or all of your investment. As a result, the market value of the Notes prior to maturity will be affected by changes in the market’s view of our creditworthiness. Any actual or anticipated decline in our credit ratings or increase in the credit spreads charged by the market for taking our credit risk is likely to adversely affect the market value of the Notes.

Valuation- and Market-related Risks

The market price of the Notes will be influenced by many unpredictable factors.

Several factors, many of which are beyond our control, will influence the value of the Notes in the secondary market and the price at which Jefferies LLC may be willing to purchase or sell the Notes in the secondary market, including the value, volatility (frequency and magnitude of changes in value) and dividend yield of the Underlyings, interest and yield rates in the market, time remaining until the Notes mature, geopolitical conditions and economic, financial, political, regulatory or judicial events that affect the Underlyings or equities markets generally and which may affect the Observation Values or Final Value of the Underlyings and any actual or anticipated changes in our credit ratings or credit spreads. The value of the Underlyings may be, and has recently been, volatile, and we can give you no assurance that the volatility will lessen. See “The Underlyings” below. You may receive less, and possibly significantly less, than the Stated Principal Amount per Note if you try to sell your Notes prior to maturity.

The estimated value of the Notes on the Pricing Date, based on Jefferies LLC proprietary pricing models at that time and our internal funding rate, will be less than the Issue Price.

The difference is attributable to certain costs associated with selling, structuring and hedging the Notes that are included in the Issue Price. These costs include (i) the selling concessions paid in connection with the offering of the Notes, (ii) hedging and other costs incurred by us and our affiliates in connection with the offering of the Notes and (iii) the expected profit (which may be more or less than actual profit) to Jefferies LLC or other of our affiliates in connection with hedging our obligations under the Notes. These costs adversely affect the economic terms of the Notes because, if they were lower, the economic terms of the Notes would be more favorable to you. The economic terms of the Notes are also likely to be adversely affected by the use of our internal funding rate, rather than our secondary market rate, to price the Notes. See “The estimated value of the Notes would be lower if it were calculated based on our secondary market rate” below.

The estimated value of the Notes was determined for us by our subsidiary using proprietary pricing models.

Jefferies LLC derived the estimated value disclosed on the cover page of this pricing supplement from its proprietary pricing models at that time. In doing so, it may have made discretionary judgments about the inputs to its models, such as the volatility of the Underlyings. Jefferies LLC’s views on these inputs and assumptions may differ from your or others’ views, and as an agent in this offering, Jefferies LLC’s interests may conflict with yours. Both the models and the inputs to the models may prove to be wrong and therefore not an accurate reflection of the value of the Notes. Moreover, the estimated value of the Notes set forth on the cover page of this pricing supplement may differ from the value that we or our affiliates may determine for the Notes for other purposes, including for accounting purposes. You should not invest in the Notes because of the estimated value of the Notes. Instead, you should be willing to hold the Notes to maturity irrespective of the initial estimated value.

Since the estimated value of the Notes is a function of the underlying assumptions and construction of Jefferies LLC’s proprietary derivative-pricing model, modifications to this model will impact the estimated value calculation. Jefferies LLC’s proprietary models are subject to ongoing review and modification, and Jefferies LLC may change them at any time and for a variety of reasons. In the event of a model change, prior descriptions of the model and computations based on the older model will be superseded, and calculations of estimated value under the new model may differ significantly from those under the older model. Further, model changes may cause a larger impact on the estimated value of a note with a

PS-7

Table of Contents

particular return formula than on a similar note with a different return formula. For example, to the extent a return formula contains a participation rate of greater than 100%, model changes may cause a larger impact on the estimated value of that note than on a similar note without such participation rate.

The estimated value of the Notes would be lower if it were calculated based on our secondary market rate.

The estimated value of the Notes included in this pricing supplement is calculated based on our internal funding rate, which is the rate at which we are willing to borrow funds through the issuance of the Notes. Our internal funding rate is generally lower than our secondary market rate, which is the rate that Jefferies LLC will use in determining the value of the Notes for purposes of any purchases of the Notes from you in the secondary market. If the estimated value included in this pricing supplement were based on our secondary market rate, rather than our internal funding rate, it would likely be lower. We determine our internal funding rate based on factors such as the costs associated with the Notes, which are generally higher than the costs associated with conventional debt securities, and our liquidity needs and preferences. Our internal funding rate is not the same as the interest that is payable on the Notes.

Because there is not an active market for traded instruments referencing our outstanding debt obligations, Jefferies LLC determines our secondary market rate based on the market price of traded instruments referencing our debt obligations, but subject to adjustments that Jefferies LLC makes in its sole discretion. As a result, our secondary market rate is not a market-determined measure of our creditworthiness, but rather reflects the market’s perception of our creditworthiness as adjusted for discretionary factors such as Jefferies LLC’s preferences with respect to purchasing the Notes prior to maturity.

The estimated value of the Notes is not an indication of the price, if any, at which Jefferies LLC or any other person may be willing to buy the Notes from you in the secondary market.

Any such secondary market price will fluctuate over the term of the Notes based on the market and other factors described in the next risk factor. Moreover, unlike the estimated value included in this pricing supplement, any value of the Notes determined for purposes of a secondary market transaction will be based on our secondary market rate, which will likely result in a lower value for the Notes than if our internal funding rate were used. In addition, any secondary market price for the Notes will be reduced by a bid-ask spread, which may vary depending on the aggregate stated principal amount of the Notes to be purchased in the secondary market transaction, and the expected cost of unwinding related hedging transactions. As a result, it is likely that any secondary market price for the Notes will be less than the Issue Price.

The Notes will not be listed on any securities exchange and secondary trading may be limited.

The Notes will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the Notes. Jefferies LLC may, but is not obligated to, make a market in the Notes and, if it once chooses to make a market, may cease doing so at any time. When it does make a market, it will generally do so for transactions of routine secondary market size at prices based on its estimate of the current value of the Notes, taking into account its bid/offer spread, our credit spreads, market volatility, the notional size of the proposed sale, the cost of unwinding any related hedging positions, the time remaining to maturity and the likelihood that it will be able to resell the Notes. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Notes easily. Since other broker-dealers may not participate significantly in the secondary market for the Notes, the price at which you may be able to trade your Notes is likely to depend on the price, if any, at which Jefferies LLC is willing to transact. If, at any time, Jefferies LLC were to cease making a market in the Notes, it is likely that there would be no secondary market for the Notes. Accordingly, you should be willing to hold your Notes to maturity.

Conflict-related Risks

The Calculation Agent, which is a subsidiary of ours, will make determinations with respect to the Notes.

As Calculation Agent, Jefferies Financial Services, Inc. will determine the Initial Value of each Underlying, will determine the Observation Values and Final Value of each Underlying and will calculate the amount of cash you receive during the term of the Notes. Moreover, certain determinations made by Jefferies Financial Services, Inc., in its capacity as Calculation Agent, may require it to exercise discretion and make subjective judgments, such as with respect to the occurrence or non-occurrence of Market Disruption Events, changes to the Adjustment Factor and the selection of a successor index or calculation of the Observation Value or Final Value in the event of a Market Disruption Event or discontinuance of an Underlying. These potentially subjective determinations may adversely affect payments on the Notes.

Our trading and hedging activities may create conflicts of interest with you.

We or one or more of our subsidiaries, including Jefferies LLC, may engage in trading activities related to the Notes that are not for your account or on your behalf. We expect to enter into arrangements to hedge the market risks associated with our obligation to pay the amounts due under the Notes. We may seek competitive terms in entering into the hedging

PS-8

Table of Contents

arrangements for the Notes, but are not required to do so, and we may enter into such hedging arrangements with one of our subsidiaries or affiliates. This hedging activity is expected to result in a profit to those engaging in the hedging activity, which could be more or less than initially expected, but which could also result in a loss for the hedging counterparty. These trading and hedging activities may present a conflict of interest between your interest as a holder of the Notes and the interests we and our subsidiaries may have in our proprietary accounts, in facilitating transactions for our customers, and in accounts under our management.

Underlying-related Risks

Investing in the Notes is not equivalent to investing in any Underlying.

Investing in the Notes is not equivalent to investing in any Underlying or the securities represented by or included in any Underlying. As an investor in the Notes, you will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Underlyings or the securities represented by or included in any Underlying.

Historical performance of the Underlyings should not be taken as an indication of the future performance of the Underlyings during the term of the Notes.

The actual performance over the term of the Notes of the Underlyings as well as any payment on the Notes may bear little relation to the historical performance of the Underlyings. The future performance of the Underlyings may differ significantly from their historical performance, and no assurance can be given as to the value of the Underlyings during the term of the Notes. It is impossible to predict whether the value of the Underlyings will rise or fall. We cannot give you assurance that the performance of the Underlyings will not adversely affect any payment on the Notes.

You must rely on your own evaluation of the merits of an investment linked to the Underlyings.

In the ordinary course of their businesses, we or our subsidiaries may have expressed views on expected movements in the Underlyings or the securities represented by or included in the Underlyings, and may do so in the future. These views or reports may be communicated to our clients and clients of our subsidiaries. However, these views are subject to change from time to time. Moreover, other professionals who deal in markets relating to the Underlyings may at any time have views that are significantly different from ours or those of our subsidiaries. For these reasons, you should consult information about the Underlyings or the securities represented by or included in the Underlyings from multiple sources, and you should not rely on the views expressed by us or our subsidiaries.

Neither the offering of the Notes nor any views which we or our subsidiaries from time to time may express in the ordinary course of their businesses constitutes a recommendation as to the merits of an investment in the Notes.

Adjustments to an Underlying or its Underlying Index could adversely affect the value of the Notes.

The investment advisor or index publisher of an Underlying or its Underlying Index (each, an “Index Publisher”) may add, delete or substitute the securities included in that Underlying or Underlying Index or make other methodological changes that could change the value of that Underlying or Underlying Index . An investment advisor or Index Publisher may discontinue or suspend calculation or publication of the applicable Underlying or Underlying Index at any time. In these circumstances, the Calculation Agent will have the sole discretion to calculate the value of an Underlying by reference to its Underlying Index or substitute a successor index that is comparable to the discontinued Underlying or Underlying Index and is not precluded from considering indices that are calculated and published by the Calculation Agent or any of its affiliates. If the Calculation Agent determines that there is no appropriate successor index, payments on the Notes will be an amount based on the closing prices at maturity of the securities included in the Underlying at the time of such discontinuance, without rebalancing or substitution, computed by the Calculation Agent in accordance with the formula for calculating the Underlying last in effect prior to discontinuance of the Underlying.

The performance and market price of the GDX, particularly during periods of market volatility, may not correlate with the performance of its Underlying Index, the performance of the component securities of its Underlying Index or the net asset value per share of the GDX.

ETFs generally do not fully replicate their applicable Underlying Index and may hold securities that are different than those included in their applicable Underlying Index. In addition, the performance of an ETF will reflect additional transaction costs and fees that are not included in the calculation of its Underlying Index. All of these factors may lead to a lack of correlation between the performance of an ETF and its Underlying Index. In addition, corporate actions (such as mergers and spin-offs) with respect to the equity securities underlying an ETF may impact the variance between the performance of such ETF and its Underlying Index. Finally, because the shares of an ETF are traded on an exchange and are subject to market supply and investor demand, the market price of one share of an ETF may differ from the net asset value per share of such ETF.

In particular, during periods of market volatility, or unusual trading activity, trading in the securities underlying an ETF may be disrupted or limited, or such securities may be unavailable in the secondary market. Under these circumstances, the

PS-9

Table of Contents

liquidity of an ETF may be adversely affected, market participants may be unable to calculate accurately the net asset value per share of such ETF, and their ability to create and redeem shares of such ETF may be disrupted. Under these circumstances, the market price of an ETF may vary substantially from the net asset value per share of such ETF or the level of its Underlying Index.

For all of the foregoing reasons, the performance of the GDX may not correlate with the performance of its Underlying Index, the performance of the component securities of its Underlying Index or the net asset value per share of the GDX. Any of these events could materially and adversely affect the price of the GDX and, by extension, adversely affect the value of the Notes. Additionally, if market volatility or these events were to occur on a Coupon Observation Date, Call Observation Date or the Valuation Date with respect to the GDX, the Calculation Agent would maintain discretion to determine whether such market volatility or events have caused a Market Disruption Event to occur, and such determination would affect payments on the Notes. If the Calculation Agent determines that no Market Disruption Event has taken place, payments on the Notes would be based solely on the ETF Closing Price per share of the GDX on the relevant Coupon Observation Date, Call Observation Date or the Valuation Date, even if the GDX is underperforming its Underlying Index or the component securities of its Underlying Index and/or trading below the net asset value per share of the GDX.

The antidilution adjustments the Calculation Agent is required to make do not cover every event that could affect the GDX.

The Calculation Agent will adjust any payments on the Notes for certain events affecting the GDX. However, the Calculation Agent will not make an adjustment for every event that could affect the GDX. If an event occurs that does not require the Calculation Agent to adjust the payments on the Notes, the market price of the Notes may be materially and adversely affected.

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 held by the GDX are issued by companies whose primary line of business is directly associated with the gold and silver mining industries. As a result, the value of the Notes may be subject to greater volatility and 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 GDX 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 GDX’s returns. If a natural disaster or other event with a significant economic impact occurs in a region where the companies in which the GDX invests operate, that disaster or event could negatively affect the profitability of these companies and, in turn, the GDX’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 GDX and the price of the GDX during the term of the securities, which may adversely affect the value of your Notes.

In addition, the GDX is classified as “non-diversified” under the Investment Company Act of 1940, as amended. A non-diversified fund generally may invest a larger percentage of its assets in the securities of a smaller number of issuers. As a result, the GDX may be more susceptible to the risks associated with these particular companies, or to a single economic, political or regulatory occurrence affecting these companies.

An Investment In The Notes Is Subject To Risks Associated With Foreign Securities Markets, Including Emerging Markets.

Some of the securities held by the GDX are issued by foreign companies and you should be aware that investments in securities linked to the value of foreign equity securities involve particular risks. Foreign securities markets may have less liquidity and may be more volatile than the U.S. securities markets, and market developments may affect foreign markets differently than U.S. securities markets. Direct or indirect government intervention to stabilize a foreign securities market,

PS-10

Table of Contents

as well as cross-shareholdings in foreign companies, may affect trading prices and volumes in those markets. Also, there is generally less publicly available information about non-U.S. companies that are not subject to the reporting requirements of the SEC, and non-U.S. companies are subject to accounting, auditing and financial reporting standards and requirements that differ from those applicable to U.S. reporting companies.

The prices and performance of securities of non-U.S. companies are subject to political, economic, financial, military and social factors which could negatively affect foreign securities markets, including the possibility of recent or future changes in a foreign government’s economic, monetary and fiscal policies, the possible imposition of, or changes in, currency exchange laws or other laws or restrictions applicable to foreign companies or investments in foreign equity securities, the possibility of imposition of withholding taxes on dividend income, the possibility of fluctuations in the rate of exchange between currencies, the possibility of outbreaks of hostility or political instability and the possibility of natural disaster or adverse public health developments. Moreover, the relevant non-U.S. economies may differ favorably or unfavorably from the U.S. economy in important respects, such as growth of gross national product, rate of inflation, trade surpluses or deficits, capital reinvestment, resources and self-sufficiency.

In addition, the GDX may include companies in countries with emerging markets. Countries with emerging markets may have relatively unstable governments, may present the risks of nationalization of businesses, restrictions on foreign ownership and prohibitions on the repatriation of assets, and may have less protection of property rights 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 (due to economic dependence upon commodity prices and international trade), and may suffer from extreme and volatile debt burdens, currency devaluations 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.

The securities included in the GDX may be listed on a foreign stock exchange. A foreign stock exchange may impose trading limitations intended to prevent extreme fluctuations in individual security prices and may suspend trading in certain circumstances. These actions could limit variations in the closing price of the GDX which could, in turn, adversely affect the value of the notes.

The Notes Are Subject To Foreign Currency Exchange Rate Risk.

The GDX holds securities traded outside of the United States. Its share price will fluctuate based upon its net asset value (“NAV”), which will in turn depend in part upon changes in the value of the currencies in which the securities held by the GDX are traded. Accordingly, investors in the notes will be exposed to currency exchange rate risk with respect to each of the currencies in which the securities held by the GDX are traded. An investor’s net exposure will depend on the extent to which these currencies strengthen or weaken against the U.S. dollar. If the dollar strengthens against these currencies, the NAV of the GDX will be adversely affected and the price of the GDX may decrease.

The Stocks Held By The GDX Are Concentrated In One Sector.

The GDX holds securities issued by companies in the gold miners sector. As a result, some of the stocks that will determine the performance of the notes are concentrated in one sector. Although an investment in the notes will not give holders any ownership or other direct interests in the securities held by the GDX, the return on an investment in the notes will be subject to certain risks associated with a direct equity investment in companies in this sector. Accordingly, by investing in the notes, you will not benefit from the diversification which could result from an investment linked to companies that operate in multiple sectors.

The GDX recently changed the index it tracks.

Previously, the GDX tracked the NYSE® Arca Gold Miners Index®, but, after the close of trading on September 19, 2025, the GDX began tracking the MarketVector Global Gold Miners Index. Any historical information about the performance of the GDX for any period before the close of trading on September 19, 2025 will be during a period in which the GDX tracked a different index, and therefore should not be considered information relevant to how the GDX will perform as it tracks the MarketVector Global Gold Miners Index. In addition, there can be no assurance that the GDX will not further change the underlying index it tracks in the future.

The MarketVector Global Gold Miners Index, which is the GDX’s underlying index, has a limited operating history.

PS-11

Table of Contents

The MarketVector Global Gold Miners Index, which is the GDX’s underlying index, was launched on June 3, 2025. Because the MarketVector Global Gold Miners Index has no live closing level history prior to that date, limited live historical closing level information will be available for you to consider in making an independent investigation of the MarketVector Global Gold Miners Index’s performance and therefore the GDX’s performance, which may make it difficult for you to make an informed decision with respect to your Notes. As a result, the return on your Notes may involve greater risk than those that are linked to ETFs tracking underlying indices with a more established record of performance.

Tax-related Risks

The tax consequences of an investment in your Notes are uncertain.

The tax consequences of an investment in your Notes are uncertain, both as to the timing and character of any inclusion in income in respect of your Notes.

The Internal Revenue Service announced on December 7, 2007 that it is considering issuing guidance regarding the tax treatment of an instrument such as your Notes, and any such guidance could adversely affect the value and the tax treatment of your Notes. Among other things, the Internal Revenue Service may decide to require the holders to accrue ordinary income on a current basis and recognize ordinary income on payment at maturity, and could subject non-U.S. investors to withholding tax. Furthermore, in 2007, legislation was introduced in Congress that, if enacted, would have required holders that acquired instruments such as your Notes after the bill was enacted to accrue interest income over the term of such instruments. It is not possible to predict whether a similar or identical bill will be enacted in the future, or whether any such bill would affect the tax treatment of your Notes. We describe these developments in more detail under “Supplemental Discussion of U.S. Federal Income Tax Consequences – U.S. Holders – Possible Change in Law” below. You should consult your tax advisor about this matter. Except to the extent otherwise provided by law, we intend to continue treating the Notes for U.S. federal income tax purposes in accordance with the treatment described under “Supplemental Discussion of U.S. Federal Income Tax Consequences” below unless and until such time as Congress, the Treasury Department or the Internal Revenue Service determine that some other treatment is more appropriate. Please also consult your tax advisor concerning the U.S. federal income tax and any other applicable tax consequences to you of owning your Notes in your particular circumstances.

Your Notes may be subject to the constructive ownership rules.

There exists a risk that the constructive ownership rules of Section 1260 of the Internal Revenue Code could apply to all or a portion of your Notes. If all or a portion of your Notes were subject to the constructive ownership rules, then all or a portion of any long-term capital gain that you realize upon the sale, exchange, redemption or maturity of your Notes would be re-characterized as ordinary income (and you would be subject to an interest charge on deferred tax liability with respect to such re-characterized capital gain) to the extent that such capital gain exceeds the amount of “net underlying long-term capital gain” (as defined in Section 1260 of the Internal Revenue Code). Because the application of the constructive ownership rules is unclear you are strongly urged to consult your tax advisor with respect to the possible application of the constructive ownership rules to your investment in the Notes.

Information provided to or filed with the SEC relating to the GDX under the Securities Exchange Act of 1934, as amended, can be located by reference to its Central Index Key, or CIK, 0001137360 through the SEC’s website at http://www.sec.gov. Additional information about the GDX may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. We have not made any independent investigation as to the accuracy or completeness of such information.

The GDX is an investment portfolio maintained, managed and advised by the Trust. The GDX is an exchange traded fund that trades on NYSE Arca under the ticker symbol “GDX.” The GDX seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the MarketVector Global Gold Miners Index (the “underlying index”). The underlying index is comprised of publicly traded companies primarily involved in the gold and silver mining industries. The GDX utilizes a “passive” or “indexing” investment approach in attempting to track the performance of the underlying index by investing in a portfolio of securities that generally replicates the underlying index. The GDX will normally invest at least 80% of its total assets in common stocks that comprise the underlying index.

Prior to the close of trading on September 19, 2025, the GDX tracked the NYSE^® Arca Gold Miners Index^®.

The Underlying Index

The underlying index is a thematic index tracking the performance of companies involved in the gold and silver mining industries. The underlying index is calculated, maintained and published by MarketVector, the index sponsor. The underlying index was launched on June 3, 2025 with a base index value of 1,000.00 as of April 30, 2006.

The underlying index is reported by Bloomberg L.P. under the ticker symbol “MVGDXTR.”

The Index Universe

The underlying index only includes companies with at least 50% (25% for current components) of their:

☐

revenues from gold and/or silver mining, royalties, and/or streaming; and/or

☐

mining mineral resources from gold and/or silver.

The index universe will include 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, excluding limited partnerships.

Due to certain restrictions security listings on exchanges in the following countries do not qualify for the index universe: Bahrain, China (domestic market), India, Kuwait, Luxembourg, Oman, Qatar, Russia, Saudi Arabia, United Arab Emirates, and Vietnam. Furthermore, securities listed on the following exchanges or exchange segments are not eligible for this index: Paris Euronext Auction, Hamburger Boerse, Boerse Berlin, Oslo Euronext Growth, London Stock Exchange (AIM, AIMI, ASQ1, ASQ2, ASX1, ASXN, SFM2, SFM3, SSQ3, SSX3, SSX4, EQS). 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 this exchange.

This rule is applicable for newly spun-off companies and post-merger/acquisition SPACs (using the merger/acquisition date like an IPO date) as well.

Eligibility Universe

Share Class

One share class of each company in the investable universe is included in the eligible universe. In case more than one share class fulfills the above specified market capitalization and liquidity rules, only the largest share class by free-float market capitalization qualifies for the eligible universe. In exceptional cases (e.g. significantly higher liquidity), MarketVector can decide for a different share class.

In case the free-float market capitalization of a currently not included share class of an index component exceeds the free-float market capitalization of the currently selected share class by at least 25% and fulfills all market capitalization and liquidity eligibility criteria for non-components the currently selected share class will be replaced by the larger one.

In exceptional cases (e.g. significantly higher liquidity), MarketVector can decide to keep the current share class instead.

Pricing Source

PS-14

Table of Contents

For each company in the investable universe one pricing source qualifies for the eligible universe. In cases where a company has multiple listings (e.g. ADRs, GDRs, or listings on markets other than in the home country), the price sources will be selected to the eligible universe in the following order:

US price source;

UK price source- London Stock Exchange International Order Book only;

Home-market price source;

Most liquid foreign-market price source.

Once a company has qualified for the investable universe, only the most liquid single exchange price source within the country qualifies for the eligible universe. In exceptional cases, MarketVector can assign alternative pricing sources.

Index Review

Review Schedule

Components of the underlying index are reconstituted and rebalanced on a quarterly basis in March, June, September, and December according to the following schedule:

The eligible universe and component selection is determined based on the closing data on the last business day in February, May, August, and November. If a security does not trade on the last business day in February, May, August, or November, the last available price for this security will be used.

Component weights are determined based on closing data as of the Wednesday prior to the second Friday of March, June, September, and December. If a security does not trade on the Wednesday prior to the second Friday of March, June, September, and December, the last available closing data for this security will be used.

The underlying review and rebalance data (i.e. weights, shares outstanding, free-float factors, and new weighting cap factors) is announced on the second Friday of March, June, September and December.

Changes will be implemented and based on the closing prices as of the third Friday of March, June, September, and December. If the third Friday is not a business day, the review will take place on the last business day before the third Friday. If a security does not trade on the third Friday of March, June, September, or December, then the last available price for this security will be used. Changes become effective on the next index dissemination day.

Selection Procedure

Upon an index reconstitution, securities included in the eligible universe are selected to the underlying index based on the following procedure. The underlying index targets a coverage of 90% of the free-float market capitalization of the eligible universe with a minimum of 25 components.

All securities in the eligible universe are sorted in terms of free-float market capitalization in descending order.

Securities covering the top 85% of the free-float market capitalization of the eligible universe qualify for selection.

Current components between 85% and 98% of the free-float market capitalization of the eligible universe also qualify for selection.

If the coverage is still below 90% of the free-float market capitalization of the eligible universe or the number of components in the underlying index is still below 25, the largest remaining securities will be selected until both the target coverage and minimum number of components are reached.

In case the number of eligible securities is below the minimum of 25, additional securities are added by MarketVector’s decision until the number of securities selected to the underlying index reaches the minimum of 25 components.

Weighting Scheme

Upon an index rebalance, components selected to the underlying index will be weighted according to a modified float-adjusted market cap weighting strategy:

All index components are weighted by their free-float market capitalization.

All components with more than 50% exposure to gold-related activities that exceed 4.5% in weight but at least the largest five and at the maximum the largest 9 of these components are grouped together (so called “Large-Weights”). All other components are grouped together as well (so called “Small-Weights”).

PS-15

Table of Contents

The aggregated weighting of the Large-Weights is capped at 45%:

☐

Large-Weights: If the aggregated weighting of all components in Large-Weight exceeds 45%, then a capping factor is calculated to bring the weighting down to 45%- at the same time a second capping factor for the Small-Weights is calculated to increase the aggregated weight to 55%. These two factors are then applied to all components in the Large-Weights or the Small-Weights respectively.

☐

Large-Weights: The maximum weight for any single security is 20% and the minimum weighting is 5%. If a security is above the maximum or below the minimum weight, then the weight will be reduced to the maximum weight or increased to the minimum weight and the excess weight shall be redistributed proportionally across all other remaining index constituents in the Large-Weights.

☐

Small-Weights: The maximum weight for any single security is 4.5%. If a security is above the maximum weight, then the weight will be reduced to the maximum weight and the excess weight shall be redistributed proportionally across all other remaining index constituents in the Small-Weights.

In case the aggregated weight of all index components with less than 50% exposure to gold-related activities 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 gold-related activities within the Small-Weights.

Index Maintenance

Changes to Free-Float Factors and Number of Shares

Changes to the number of shares or the free-float factors due to corporate actions like stock dividends, splits, rights issues, spin-offs etc. are implemented immediately and will be effective the next trading day (i.e., the ex-date). Any secondary issuance, share repurchase, buyback, tender offer, Dutch auction, exchange offer, bought deal equity offering or prospectus offering will be updated at the quarterly review if the change is smaller than 10%. Changes larger than 10% will be pre-announced (three trading days notice) and implemented on the first dissemination day of the following month (on a best effort basis). If necessary and information is available, resulting float changes will be taken into consideration.

Changes due to Mergers & Takeovers

A merger or takeover is deemed successful if it has been declared wholly unconditional and has received approval of all regulatory agencies with jurisdiction over the transaction. The result of a merger or takeover is typically one surviving security and one or more non-surviving securities that may not necessarily be delisted from the respective trading system(s). The following treatments are applied for mergers and takeovers containing stock terms:

☐

If an index component merges with or takes over another index component: The surviving security remains in the underlying index and the other security is deleted immediately from the underlying index. Its shares and float are adjusted according to the terms of the merger/takeover. The index market capitalization of the merged company corresponds to the market capitalization of the two separate companies.

☐

If a non-index component merges with or takes over an index component:

☐

If the surviving security meets the eligible index universe requirements, it will be added to the underlying index. Its shares and float will be adjusted according to the terms of the merger/takeover and will replace the current index component.

☐

If the surviving security does not meet the eligible index universe requirements, it will not be added to the underlying index and the current index component will be deleted immediately from the underlying index. The following treatments are applied for mergers and takeovers with cash terms only:

☐

If a non-index component merges with or takes over an index component:

☐

The index component will be deleted.

Changes due to Spin-Offs

The spun-off company will be added to the underlying index where the parent company is an index constituent according to the transaction terms, with a price of zero, on the ex-date. If the spun-off does not start trading on the ex-date, a fixed indicative price will be used until the first trading day. If an indicative price is not possible to be calculated, the spun-off company will be added with a price of zero to the underlying index. If the spun-off does not qualify for the underlying index, it will be deleted after two trading days based on its respective closing price.

PS-16

Table of Contents

Additions due to Replacements

On an ongoing basis, for all corporate events that result in a security deletion from the underlying index, the deleted security will be replaced with the highest ranked non-component on the most recent selection list immediately only if the number of components in the underlying index would drop below 20. The replacement security will be added at the same weight as the deleted security. Only in case the number of components drops below its minimum due to a merger of two or more index components, the replacement security will be added with its uncapped free-float market capitalization weight.

In all other cases, i.e. there is no replacement. The additional weight resulting from the deletion will be redistributed proportionally across all other index constituents.

In case the number of index components drops below the minimum component number and no non-component security is eligible as a replacement, the determination of the addition is subject to MarketVector’s decision.

Index Calculation

The underlying index is calculated using the Laspeyres’ formula:

Where (for all securities (i) in the underlying index):

	p_i	= security price,
	q_i	=number of shares,
	f f_i	=free-float factor,
	fx_i	=exchange rate (local currency to index currency),
	cf_i	= weighting cap factor (if applicable, otherwise set to 1),
	M	=free-float market capitalization of the underlying index,
	D	=divisor.

Divisor Adjustments

Index maintenance, reflecting changes in shares outstanding, capital actions, addition or deletion of securities to the underlying index, should not change the level of the underlying index. This is accomplished with an adjustment to the divisor. Any change to the securities in the underlying index that alters the total market value of the underlying index while holding security prices constant will require a divisor adjustment.

Where ∆MC is the difference between closing and adjusted closing market capitalization of the underlying index.

Free-Float

The underlying index is free-float adjusted—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

PS-17

Table of Contents

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.

Corporate Action Related Adjustments

Corporate actions range widely from routine share issuances or buybacks to unusual events like spin-offs or mergers. These are listed on the table below with notes about the necessary changes and whether the divisor will be adjusted.

p_i= security price;

q_ic = number of shares.

Type of Corporate Action	Treatment	Divisor Adjustment
Cash dividend	(In total return gross indexes the withholding tax is 0)	Yes
Special cash dividend	(In total return gross indexes the withholding tax is 0)	Yes
Split	Shareholders receive ‘B’ new shares for every ‘A’ share held.	No
Rights Offering	Shareholders receive ‘B’ new shares for every ‘A’ share held. If the subscription-price is either not available or not smaller than the closing price, no adjustment will be made.	Yes
Stock dividend (withholding taxes are applied, if applicable)	Shareholders receive ‘B’ new shares for every ‘A’ share held.	No
Stock dividend from treasury		Yes

PS-18

Table of Contents

(withholding taxes are applied, if applicable)	Stock dividends from treasury are adjusted as ordinary cash dividends. Shareholders receive ‘B’ new shares for every ‘A’ share held.
Stock dividend of a different company security (withholding taxes are applied, if applicable)	The shares of the different company will be added according to the terms.	No
Addition/Deletion of a company	Net change in free-float market value determines the divisor adjustment.	Yes
Changes due to a merger/takeover	Net change in free-float market value determines the divisor adjustment. In case of no change, the divisor change is 0.	Yes
Spin-offs	Shareholders receive ‘B’ new shares for every ‘A’ share held.	No
Changes in shares outstanding	Net change in free-float market value determines the divisor adjustment. In case of no change, the divisor change is 0.	Yes

With corporate actions where cash dividends or other corporate assets are distributed to shareholders, the price of the security will drop on the ex-dividend day (the first day when a new shareholder is eligible to receive the distribution). The effect of the divisor adjustment is to prevent this price drop from causing a corresponding drop in the underlying index.

Corporate actions are announced at least four days prior to implementation.

The S&P 500^® Index

The S&P 500^® Index (the “SPX”) includes a representative sample of 500 companies in leading industries of the U.S. economy. The SPX is intended to provide an indication of the pattern of common stock price movement. The calculation of the level of the SPX is based on the relative value of the aggregate market value of the common stocks of 500 companies as of a particular time compared to the aggregate average market value of the common stocks of 500 similar companies during the base period of the years 1941 through 1943.

The SPX includes companies from eleven main groups: Communication Services; Consumer Discretionary; Consumer Staples; Energy; Financials; Health Care; Industrials; Information Technology; Real Estate; Materials; and Utilities. SPDJI may from time to time, in its sole discretion, add companies to, or delete companies from, the SPX to achieve the objectives stated above.

SPDJI calculates the SPX by reference to the prices of the constituent stocks of the SPX without taking account of the value of dividends paid on those stocks. As a result, the return on the Notes will not reflect the return you would realize if you actually owned the SPX constituent stocks and received the dividends paid on those stocks.

Computation of the SPX

While SPDJI currently employs the following methodology to calculate the SPX, no assurance can be given that SPDJI will not modify or change this methodology in a manner that may affect payment on the notes.

Historically, the market value of any component stock of the SPX was calculated as the product of the market price per share and the number of then outstanding shares of such component stock. In March 2005, SPDJI began shifting the SPX halfway from a market capitalization weighted formula to a float-adjusted formula, before moving the SPX to full float adjustment on September 16, 2005. SPDJI’s criteria for selecting stocks for the SPX did not change with the shift to float adjustment. However, the adjustment affects each company’s weight in the SPX.

Under float adjustment, the share counts used in calculating the SPX reflect only those shares that are available to investors, not all of a company’s outstanding shares. Float adjustment excludes shares that are closely held by control groups, other publicly traded companies or government agencies.

In September 2012, all shareholdings representing more than 5% of a stock’s outstanding shares, other than holdings by “block owners,” were removed from the float for purposes of calculating the SPX. Generally, these “control holders” will include officers and directors, private equity, venture capital and special equity firms, other publicly traded companies that hold shares for control, strategic partners, holders of restricted shares, ESOPs, employee and family trusts, foundations associated with the company, holders of unlisted share classes of stock, government entities at all levels (other than

PS-20

Table of Contents

government retirement/pension funds) and any individual person who controls a 5% or greater stake in a company as reported in regulatory filings. However, holdings by block owners, such as depositary banks, pension funds, mutual funds and ETF providers, 401(k) plans of the company, government retirement/pension funds, investment funds of insurance companies, asset managers and investment funds, independent foundations and savings and investment plans, will ordinarily be considered part of the float.

Treasury stock, stock options, restricted shares, equity participation units, warrants, preferred stock, convertible stock, and rights are not part of the float. Shares held in a trust to allow investors in countries outside the country of domicile, such as depositary shares and Canadian exchangeable shares are normally part of the float unless those shares form a control block. If a company has multiple classes of stock outstanding, shares in an unlisted or non-traded class are treated as a control block.

For each stock, an investable weight factor (“IWF”) is calculated by dividing the available float shares by the total shares outstanding. Available float shares are defined as the total shares outstanding less shares held by control holders. This calculation is subject to a 5% minimum threshold for control blocks. For example, if a company’s officers and directors hold 3% of the company’s shares, and no other control group holds 5% of the company’s shares, SPDJI would assign that company an IWF of 1.00, as no control group meets the 5% threshold. However, if a company’s officers and directors hold 3% of the company’s shares and another control group holds 20% of the company’s shares, SPDJI would assign an IWF of 0.77, reflecting the fact that 23% of the company’s outstanding shares are considered to be held for control. As of July 31, 2017, companies with multiple share class lines are no longer eligible for inclusion in the SPX. Constituents of the SPX prior to July 31, 2017 with multiple share class lines will be grandfathered in and continue to be included in the SPX. If a constituent company of the SPX reorganizes into a multiple share class line structure, that company will remain in the SPX at the discretion of the S&P Index Committee in order to minimize turnover.

The SPX is calculated using a base-weighted aggregate methodology. The level of the SPX reflects the total market value of all component stocks relative to the base period of the years 1941 through 1943. An indexed number is used to represent the results of this calculation in order to make the level easier to work with and track over time. The actual total market value of the component stocks during the base period of the years 1941 through 1943 has been set to an indexed level of 10. This is often indicated by the notation 1941- 43 = 10. In practice, the daily calculation of the SPX is computed by dividing the total market value of the component stocks by the “index divisor.” By itself, the index divisor is an arbitrary number. However, in the context of the calculation of the SPX, it serves as a link to the original base period level of the SPX. The index divisor keeps the SPX comparable over time and is the manipulation point for all adjustments to the SPX, which is index maintenance.

Index Maintenance

Index maintenance includes monitoring and completing the adjustments for company additions and deletions, share changes, stock splits, stock dividends, and stock price adjustments due to company restructuring or spinoffs. Some corporate actions, such as stock splits and stock dividends, require changes in the common shares outstanding and the stock prices of the companies in the SPX, and do not require index divisor adjustments.

To prevent the level of the SPX from changing due to corporate actions, corporate actions which affect the total market value of the SPX require an index divisor adjustment. By adjusting the index divisor for the change in market value, the level of the SPX remains constant and does not reflect the corporate actions of individual companies in the SPX. Index divisor adjustments are made after the close of trading and after the calculation of the SPX closing level.

Changes in a company’s shares outstanding of 5.00% or more due to mergers, acquisitions, public offerings, tender offers, Dutch auctions, or exchange offers are made as soon as reasonably possible. Share changes due to mergers or acquisitions of publicly held companies that trade on a major exchange are implemented when the transaction occurs, even if both of the companies are not in the same headline index, and regardless of the size of the change. All other changes of 5.00% or more (due to, for example, company stock repurchases, private placements, redemptions, exercise of options, warrants, conversion of preferred stock, securities, debt, equity participation units, at-the-market offerings, or other recapitalizations) are made weekly and are announced on Fridays for implementation after the close of trading on the following Friday.

Changes of less than 5.00% are accumulated and made quarterly on the third Friday of March, June, September, and December, and are usually announced two to five days prior.

If a change in a company’s shares outstanding of 5.00% or more causes a company’s IWF to change by five percentage points or more, the IWF is updated at the same time as the share change. IWF changes resulting from partial tender offers are considered on a case by case basis.

HEDGING

In order to meet our payment obligations on the Notes, at the time we issue the Notes, we may choose to enter into certain hedging arrangements (which may include call options, put options or other derivatives) with one or more of our subsidiaries. The terms of these hedging arrangements are determined based upon terms provided by our subsidiaries, and take into account a number of factors, including our creditworthiness, interest rate movements, the volatility of the Underlyings, the tenor of the Notes and the hedging arrangements. The economic terms of the Notes depend in part on the terms of these hedging arrangements.

The hedging arrangements may include hedging related charges, reflecting the costs associated with, and our subsidiaries’ profit earned from, these hedging arrangements. Since hedging entails risk and may be influenced by unpredictable market forces, actual profits or losses from these hedging transactions may be more or less than this amount.

SUPPLEMENTAL DISCUSSION OF U.S. FEDERAL INCOME TAX CONSEQUENCES

The following section supplements the discussion of U.S. federal income taxation in the accompanying product supplement.

The following section is the opinion of Sidley Austin LLP, our counsel. In addition, it is the opinion of Sidley Austin LLP that the characterization of the Notes for U.S. federal income tax purposes that will be required under the terms of the Notes, as discussed below, is a reasonable interpretation of current law.

This section does not apply to you if you are a member of a class of holders subject to special rules, such as:

■

a dealer in securities or currencies;

■

a trader in securities that elects to use a mark-to-market method of accounting for your securities holdings;

■

a bank;

■

a life insurance company;

■

a tax exempt organization;

■

a partnership;

■

a regulated investment company;

■

an accrual method taxpayer subject to special tax accounting rules as a result of its use of financial statements;

■

a common trust fund;

■

a person that owns a Note as a hedge or that is hedged against interest rate risks;

■

a person that owns a Note as part of a straddle or conversion transaction for tax purposes; or

■

a U.S. holder (as defined below) whose functional currency for tax purposes is not the U.S. dollar.

Although this section is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), its legislative history, existing and proposed regulations under the Code, published rulings and court decisions, all as currently in effect, no statutory, judicial or administrative authority directly addresses how your Notes should be treated for U.S. federal income tax purposes, and as a result, the U.S. federal income tax consequences of your investment in your Notes are uncertain. Moreover, these laws are subject to change, possibly on a retroactive basis.

You should consult your tax advisor concerning the U.S. federal income tax and any other applicable tax consequences of your investments in the Notes, including the application of state, local or other tax laws and the possible effects of changes in federal or other tax laws.

U.S. Holders

This section applies to you only if you are a U.S. Holder that holds your Notes as a capital asset for tax purposes. You are a “U.S. Holder” if you are a beneficial owner of each of your Notes and you are:

■

a citizen or resident of the United States;

■

a domestic corporation;

■

an estate whose income is subject to U.S. federal income tax regardless of its source; or

■

a trust if a United States court can exercise primary supervision over the trust’s administration and one or more United States persons are authorized to control all substantial decisions of the trust.

Tax Treatment

You will be obligated pursuant to the terms of the Notes — in the absence of a change in law, an administrative determination or a judicial ruling to the contrary — to characterize your Notes for all tax purposes as income-bearing pre-paid derivative contracts in respect of the Underlyings. Except as otherwise stated below, the discussion herein assumes that the Notes will be so treated.

PS-25

Table of Contents

Coupon payments that you receive should be included in ordinary income at the time you receive the payment or when the payment accrues, in accordance with your regular method of accounting for U.S. federal income tax purposes.

Upon the sale, exchange, redemption or maturity of your Notes, you should recognize capital gain or loss in an amount equal to the difference, if any, between the amount of cash you receive at such time (excluding any amounts attributable to accrued and unpaid periodic Coupon Payments, which will be taxable as described above) and your tax basis in the Notes. Your tax basis in the Notes will generally be equal to the amount that you paid for the Notes. If you hold your Notes for more than one year, such gain or loss generally will be long-term capital gain or loss. If you hold your Notes for one year or less, such gain or loss generally will be short-term capital gain or loss. Short-term capital gains are generally subject to tax at the marginal tax rates applicable to ordinary income.

In addition, the constructive ownership rules of Section 1260 of the Internal Revenue Code could apply to all or a portion of your Notes. If all or a portion of your Notes were subject to the constructive ownership rules, then all or a portion of any long-term capital gain that you realize upon the sale, exchange, redemption or maturity of your Notes would be re-characterized as ordinary income (and you would be subject to an interest charge on deferred tax liability with respect to such re-characterized capital gain) to the extent that such capital gain exceeds the amount of “net underlying long-term capital gain” (as defined in Section 1260 of the Internal Revenue Code). Because the application of the constructive ownership rules is unclear you are strongly urged to consult your tax advisor with respect to the possible application of the constructive ownership rules to your investment in the Notes.

We will not attempt to ascertain whether the issuer of an Underlying or the issuer of any component stock included in an Underlying that is an index would be treated as a “passive foreign investment company” (“PFIC”), within the meaning of Section 1297 of the Code. If the issuer of an Underlying or the issuer of any component stock included in an Underlying that is an index were so treated, certain adverse U.S. federal income tax consequences could possibly apply to a U.S. Holder of the Notes. You should refer to information filed with the SEC by the issuer of an Underlying or the issuer of any component stock included in an Underlying that is an index and consult your tax advisor regarding the possible consequences to you, if any, if any issuer of an Underlying or the issuer of any component stock included in an Underlying that is an index is or becomes a PFIC.

No statutory, judicial or administrative authority directly discusses how your Notes should be treated for U.S. federal income tax purposes. As a result, the U.S. federal income tax consequences of your investment in the Notes are uncertain and alternative characterizations are possible. Accordingly, we urge you to consult your tax advisor in determining the tax consequences of an investment in your Notes in your particular circumstances, including the application of state, local or other tax laws and the possible effects of changes in federal or other tax laws.

Alternative Treatments

There is no judicial or administrative authority discussing how your Notes should be treated for U.S. federal income tax purposes. Therefore, the Internal Revenue Service (“IRS”) might assert that a treatment other than that described above is more appropriate. For example, the IRS could treat your Notes as a single debt instrument subject to special rules governing contingent payment debt instruments. Under those rules, the amount of interest you are required to take into account for each accrual period would be determined by constructing a projected payment schedule for the Notes and applying rules similar to those for accruing original issue discount on a hypothetical noncontingent debt instrument with that projected payment schedule. This method is applied by first determining the comparable yield – i.e., the yield at which we would issue a noncontingent fixed rate debt instrument with terms and conditions similar to your Notes – and then determining a payment schedule as of the issue date that would produce the comparable yield. These rules may have the effect of requiring you to include interest in income in respect of your Notes prior to your receipt of cash attributable to that income.

If the rules governing contingent payment debt instruments apply, any gain you recognize upon the sale, exchange, redemption or maturity of your Notes would be treated as ordinary interest income. Any loss you recognize at that time would be ordinary loss to the extent of interest you included as income in the current or previous taxable years in respect of your Notes, and, thereafter, capital loss.

If the rules governing contingent payment debt instruments apply, special rules would apply to a person who purchases Notes at a price other than the adjusted issue price as determined for tax purposes.

It is also possible that your Notes could be treated in the manner described above, except that (1) any gain or loss that you recognize upon sale, exchange, redemption or maturity would be treated as ordinary income or loss or (2) you should not include the periodic Coupon Payments, if any, in income as you receive them but instead you should reduce your basis in your Notes by the amount of the periodic Coupon Payments you receive. You should consult your tax advisor as to the tax consequences of such characterization and any possible alternative characterizations of your Notes for U.S. federal income tax purposes.

It is also possible that the IRS could seek to characterize your Notes as notional principal contracts. It is also possible that the coupon payments would not be treated as either ordinary income or interest for U.S. federal income tax purposes, but instead would be treated in some other manner.

You should consult your tax advisor as to possible alternative characterizations of your Notes for U.S. federal income tax purposes.

Possible Change in Law

On December 7, 2007, the IRS released a notice stating that the IRS and the Treasury Department are actively considering issuing guidance regarding the proper U.S. federal income tax treatment of an instrument such as the Notes, including whether holders should be required to accrue ordinary income on a current basis and whether gain or loss should be ordinary or capital. It is not possible to determine what guidance they will ultimately issue, if any. It is possible, however, that under such guidance, holders of the Notes will ultimately be required to accrue income currently and this could be applied on a retroactive basis. The IRS and the Treasury Department are also considering other relevant issues, including whether foreign holders of such instruments should be subject to withholding tax on any deemed income accruals and whether the special “constructive ownership rules” of Section 1260 of the Code might be applied to such instruments. Except to the extent otherwise provided by law, we intend to continue treating the Notes for U.S. federal income tax purposes in accordance with the treatment described above under “Tax Treatment” unless and until such time as Congress, the Treasury Department or the IRS determine that some other treatment is more appropriate.

Furthermore, in 2007, legislation was introduced in Congress that, if enacted, would have required holders that acquired instruments such as your Notes after the bill was enacted to accrue interest income over the term of such instruments. It is not possible to predict whether a similar or identical bill will be enacted in the future, or whether any such bill would affect the tax treatment of your Notes.

It is impossible to predict what any such legislation or administrative or regulatory guidance might provide, and whether the effective date of any legislation or guidance will affect Notes that were issued before the date that such legislation or guidance is issued. You are urged to consult your tax advisor as to the possibility that any legislative or administrative action may adversely affect the tax treatment of your Notes.

Backup Withholding and Information Reporting

You will be subject to generally applicable information reporting and backup withholding requirements as discussed in the accompanying prospectus supplement under “United States Federal Taxation — U.S. Holders — Backup Withholding and Information Reporting” with respect to payments on your Notes and, notwithstanding that we do not intend to treat the Notes as debt for tax purposes, we intend to backup withhold on such payments with respect to your Notes unless you comply with the requirements necessary to avoid backup withholding on debt instruments (in which case you will not be subject to such backup withholding) as set forth under “United States Federal Taxation — U.S. Holders — Backup Withholding and Information Reporting” in the accompanying prospectus supplement. Please see the discussion under “United States Federal Taxation — U.S. Holders — Backup Withholding and Information Reporting” in the accompanying prospectus supplement for a description of the applicability of the backup withholding and information reporting rules to payments made on your Notes.

Non-U.S. Holders

This section applies to you only if you are a Non-U.S. Holder. You are a “Non-U.S. Holder” if you are the beneficial owner of Notes and are, for U.S. federal income tax purposes:

■

a nonresident alien individual;

■

a foreign corporation; or

■

an estate or trust that in either case is not subject to U.S. federal income tax on a net income basis on income or gain from the Notes.

The term “Non-U.S. Holder” does not include any of the following holders:

■

a holder who is an individual present in the United States for 183 days or more in the taxable year of disposition and who is not otherwise a resident of the United States for U.S. federal income tax purposes;

■

certain former citizens or residents of the United States; or

■

a holder for whom income or gain in respect of the notes is effectively connected with the conduct of a trade or business in the United States.

PS-27

Table of Contents

Such holders should consult their tax advisors regarding the U.S. federal income tax consequences of an investment in the Notes.

Because the U.S. federal income tax treatment (including the applicability of withholding) of the periodic Coupon Payments on the Notes is uncertain, in the absence of further guidance, we intend to withhold on the periodic Coupon Payments made to you at a 30% rate or at a lower rate specified by an applicable income tax treaty under an “other income” or similar provision. We will not make payments of any additional amounts. To claim a reduced treaty rate for withholding, you generally must provide a valid Internal Revenue Service Form W-8BEN, Internal Revenue Service Form W-8BEN-E, or an acceptable substitute form upon which you certify, under penalty of perjury, your status as a non-United States holder and your entitlement to the lower treaty rate. Payments will be made to you at a reduced treaty rate of withholding only if such reduced treaty rate would apply to any possible characterization of the payments (including, for example, if the periodic Coupon Payments were characterized as contract fees). Withholding also may not apply to periodic Coupon Payments made to you if: (i) the periodic Coupon Payments are “effectively connected” with your conduct of a trade or business in the United States and are includable in your gross income for U.S. federal income tax purposes, (ii) the periodic Coupon Payments are attributable to a permanent establishment that you maintain in the United States, if required by an applicable tax treaty, and (iii) you comply with the requisite certification requirements (generally, by providing an Internal Revenue Service Form W-8ECI). If you are eligible for a reduced rate of United States withholding tax, you may obtain a refund of any amounts withheld in excess of that rate by filing a refund claim with the Internal Revenue Service.

“Effectively connected” payments includable in your United States gross income are generally taxed at rates applicable to United States citizens, resident aliens, and domestic corporations; if you are a corporate non-U.S. holder, “effectively connected” payments may be subject to an additional “branch profits tax” under certain circumstances.

We will not attempt to ascertain whether the issuer of an Underlying or the issuer of any component stock included in an Underlying that is an index would be treated as a “United States real property holding corporation” (“USRPHC”), within the meaning of Section 897 of the Code. If the issuer of an Underlying or the issuer of one or more stocks included in an Underlying that is an index were so treated, certain adverse U.S. federal income tax consequences could possibly apply to a Non-U.S. Holder of the Notes. You should refer to information filed with the SEC by the issuer of an Underlying or the issuers of the component stocks included in an Underlying that is an index and consult your tax advisor regarding the possible consequences to you, if any, if the issuer of an Underlying or the issuer of any component stock included in an Underlying that is an index is or becomes a USRPHC.

You will be subject to generally applicable information reporting and backup withholding requirements as discussed in the accompanying prospectus supplement under “United States Federal Taxation — Non-U.S. Holders — Backup Withholding and Information Reporting” with respect to payments on your Notes at maturity and, notwithstanding that we do not intend to treat the Notes as debt for tax purposes, we intend to backup withhold on such payments with respect to your Notes unless you comply with the requirements necessary to avoid backup withholding on debt instruments (in which case you will not be subject to such backup withholding) as set forth under “United States Federal Taxation — Non-U.S. Holders — Backup Withholding and Information Reporting” in the accompanying prospectus supplement.

As discussed above, alternative characterizations of the Notes for U.S. federal income tax purposes are possible. Should an alternative characterization of the Notes, by reason of a change or clarification of the law, by regulation or otherwise, cause payments at maturity with respect to the Notes to become subject to withholding tax, we will withhold tax at the applicable statutory rate and we will not make payments of any additional amounts. Prospective Non-U.S. Holders of the Notes should consult their tax advisors in this regard.

Furthermore, on December 7, 2007, the IRS released Notice 2008-2 soliciting comments from the public on various issues, including whether instruments such as your Notes should be subject to withholding. It is therefore possible that rules will be issued in the future, possibly with retroactive effect, that would cause payments on your Notes at maturity to be subject to withholding, even if you comply with certification requirements as to your foreign status.

In addition, the Treasury Department has issued regulations under which amounts paid or deemed paid on certain financial instruments (“871(m) financial instruments”) that are treated as attributable to U.S.-source dividends could be treated, in whole or in part depending on the circumstances, as a “dividend equivalent” payment that is subject to tax at a rate of 30% (or a lower rate under an applicable treaty), which in the case of any coupon payments and any amounts you receive upon the sale, exchange, redemption or maturity of your Notes, could be collected via withholding. If these regulations were to apply to the Notes, we may be required to withhold such taxes if any U.S.-source dividends are paid on the VanEck^® Gold Miners ETF or on the stocks included in the S&P 500^® Index during the term of the Notes. We could also require you to make certifications (e.g., an applicable IRS Form W-8) prior to any coupon payments or the maturity of the Notes in order to avoid or minimize withholding obligations, and we could withhold accordingly (subject to your potential right to claim a refund from the IRS) if such certifications were not received or were not satisfactory. If withholding was required, we would not be required to pay any additional amounts with respect to amounts so withheld. These regulations generally will apply to 871(m) financial instruments (or a combination of financial instruments treated as having

PS-28

Table of Contents

been entered into in connection with each other) issued (or significantly modified and treated as retired and reissued) on or after January 1, 2027, but will also apply to certain 871(m) financial instruments (or a combination of financial instruments treated as having been entered into in connection with each other) that have a delta (as defined in the applicable Treasury regulations) of one and are issued (or significantly modified and treated as retired and reissued) on or after January 1, 2017. In addition, these regulations will not apply to financial instruments that reference a “qualified index” (as defined in the regulations). We have determined that, as of the issue date of your Notes, your Notes will not be subject to withholding under these rules. In certain limited circumstances, however, you should be aware that it is possible for Non-U.S. Holders to be liable for tax under these rules with respect to a combination of transactions treated as having been entered into in connection with each other even when no withholding is required. You should consult your tax advisor concerning these regulations, subsequent official guidance and regarding any other possible alternative characterizations of your Notes for U.S. federal income tax purposes.

Foreign Account Tax Compliance Act

Legislation commonly referred to as “FATCA” generally imposes a gross-basis withholding tax of 30% on payments to certain non-U.S. entities (including financial intermediaries) with respect to certain financial instruments, unless various U.S. information reporting and due diligence requirements have been satisfied. An intergovernmental agreement between the United States and the non-U.S. entity’s jurisdiction may modify or supplement these requirements. This legislation generally applies to certain financial instruments that are treated as paying U.S.-source interest or other U.S.-source “fixed or determinable annual or periodical” (“FDAP”) income. Current provisions of the Code and Treasury regulations that govern FATCA treat gross proceeds from a sale or other disposition of obligations that can produce U.S.-source interest or FDAP income as subject to FATCA withholding. However, under recently proposed Treasury regulations, such gross proceeds would not be subject to FATCA withholding. In its preamble to such proposed regulations, the Treasury Department and the IRS have stated that taxpayers may generally rely on the proposed Treasury regulations until final Treasury regulations are issued. We will not be required to pay any additional amounts with respect to amounts withheld. Both U.S. and Non-U.S. Holders should consult their tax advisors regarding the potential application of FATCA to the Notes.

SUPPLEMENTAL PLAN OF DISTRIBUTION

Jefferies LLC, the broker-dealer subsidiary of Jefferies Financial Group Inc., will act as our Agent in connection with the offering of the Notes. Subject to the terms and conditions contained in a distribution agreement between us and Jefferies LLC, the Agent has agreed to use its reasonable efforts to solicit purchases of the Notes. We have the right to accept offers to purchase Notes and may reject any proposed purchase of the Notes. We or Jefferies LLC will pay various discounts and commissions to dealers of up to $35.00 per Note depending on market conditions. The Agent may also reject any offer to purchase Notes.

We may also sell Notes to the Agent who will purchase the Notes as principal for its own account. In that case, the Agent will purchase the Notes at a price equal to the issue price specified on the cover page of this pricing supplement, less a discount. The discount will equal the applicable commission on an agency sale of the Notes.

The Agent may resell any Notes it purchases as principal to other brokers or dealers at a discount, which may include all or part of the discount the Agent received from us. If all the Notes are not sold at the initial offering price, the Agent may change the offering price and the other selling terms.

The Agent will sell any unsold allotment pursuant to this pricing supplement from time to time in one or more transactions in the over-the-counter market, through negotiated transactions or otherwise at market prices prevailing at the time of time of sale, prices relating to the prevailing market prices or negotiated prices.

We may also sell Notes directly to investors. We will not pay commissions on Notes we sell directly.

The Agent, whether acting as agent or principal, may be deemed to be an “underwriter” within the meaning of the Securities Act. We have agreed to indemnify the Agent against certain liabilities, including liabilities under the Securities Act.

If the Agent sells Notes to dealers who resell to investors and the Agent pays the dealers all or part of the discount or commission it receives from us, those dealers may also be deemed to be “underwriters” within the meaning of the Securities Act.

The Agent is offering the Notes, subject to prior sale, when, as and if issued to and accepted by it, subject to approval of legal matters by its counsel, including the validity of the Notes, and other conditions contained in the distribution agreement, such as the receipt by the Agent of officers’ certificates and legal opinions. The Agent reserves the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

The Agent is a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). Accordingly, the offering of the notes will conform to the requirements of FINRA Rule 5121. See “Conflict of Interest” below.

The Agent is not acting as your fiduciary or advisor solely as a result of the offering of the Notes, and you should not rely upon any communication from the Agent in connection with the Notes as investment advice or a recommendation to purchase the Notes. You should make your own investment decision regarding the Notes after consulting with your legal, tax, and other advisors.

We expect to deliver the Notes against payment therefor in New York, New York on December 31, 2025, which will be the second scheduled business day following the initial pricing date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, if the initial settlement of the Notes occurs more than one business day from a pricing date, purchasers who wish to trade the Notes more than one business day prior to the Original Issue Date will be required to specify alternative settlement arrangements to prevent a failed settlement.

Jefferies LLC and any of our other broker-dealer subsidiaries may use this pricing supplement, the prospectus and the prospectus supplements for offers and sales in secondary market transactions and market-making transactions in the Notes. However, they are not obligated to engage in such secondary market transactions and/or market-making transactions. Our subsidiaries may act as principal or agent in these transactions, and any such sales will be made at prices related to prevailing market prices at the time of the sale.

FAQ

What is Jefferies (JEF) offering in this 424B2 pricing supplement?

Jefferies is offering Senior Autocallable Contingent Coupon Buffered Notes due January 2, 2031 with an aggregate principal amount of $772,000, linked to the worst-performing of the VanEck Gold Miners ETF (GDX) and the S&P 500 Index (SPX).

How do the contingent coupon payments work on the Jefferies (JEF) notes?

On each quarterly observation date, if the worst-performing underlying is at or above its coupon barrier (70% of its initial value), investors receive a $25.63 contingent coupon per $1,000 note on the related payment date. If the worst-performing underlying is below its coupon barrier, no coupon is paid for that period.

When can the Jefferies autocallable notes be redeemed early?

The notes are autocallable quarterly starting on December 29, 2026. If, on any call observation date, the worst-performing underlying is at or above its call value (100% of its initial level), the notes are automatically called and investors receive the stated principal amount plus any due contingent coupon, with no further payments.

What happens at maturity if the Jefferies notes are not called?

If the notes are not called, at maturity on January 2, 2031 investors receive the $1,000 principal per note if the final value of the worst-performing underlying is at or above its threshold value (80% of its initial level). If it is below the threshold, repayment is reduced 1% for each 1% decline below the threshold, with up to 80% of principal potentially lost. The final contingent coupon is also paid if the worst-performing underlying is at or above its coupon barrier on the final observation date.

What are the key initial levels and barriers for GDX and the S&P 500 in this Jefferies note?

The initial values are $85.85 for GDX and 6,905.74 for the S&P 500 Index. The coupon barriers are $60.10 for GDX and 4,834.02 for the S&P 500 (70% of their initial values). The threshold values are $68.68 for GDX and 5,524.59 for the S&P 500 (80% of their initial values).

What is the estimated value and pricing of the Jefferies (JEF) structured notes?

Each note has an issue price of $1,000. Jefferies estimates the value on the pricing date at $933.60 per note, reflecting issuance, structuring and hedging costs. The public offering price is 100% of principal, underwriting discounts and commissions are 3.50%, and proceeds to Jefferies before expenses are 96.50% of principal.

What are the main risks of investing in these Jefferies autocallable buffered notes?

Key risks include: potential loss of up to 80% of principal if the worst-performing underlying finishes below its threshold value; the possibility of receiving no contingent coupons if the worst-performing underlying stays below its coupon barrier; exposure only to the worst-performing of GDX and the S&P 500; credit risk of Jefferies as unsecured issuer; limited or no secondary market; and structural risks tied to the gold miners sector, equity market volatility, foreign markets and complex tax treatment.
