Insights

Structured Products Attorney

Legal structure: contingent‑payment debt with substantive tax and credit caveats.

The notes are treated as debt subject to the special rules for contingent payment debt instruments; investors must accrue income using a comparable yield and may have ordinary income treatment on gain. The offering language explicitly ties tax treatment to the constructed comparable yield and requires holders to follow those accrual rules.

Key legal dependencies include the issuercreditworthiness, the calculation agent role performed by a subsidiary, and FATCA/871(m) withholding provisions. Reviewers should note the issuercredit exposure and the stated tax mechanics when evaluating suitability.

Structured Products Strategist

Product design: capped upside with full principal repayment at maturity (credit risk applies).

The payoff combines a principal-protected-at-maturity feature (subject to issuer credit risk) with 100% participation up to a capped return (minimum cap 32.30%). The estimated value on the pricing date ($955.50) reflects embedded costs, distribution fees and internal funding rate assumptions.

Market drivers for pre-maturity value include the Index level, volatility, dividend yields, interest rates, time to maturity and issuer credit spread. Secondary market liquidity is not expected and any early sale price may be at a discount.

Market Linked Notes— Upside Participation to a Cap and Principal Return at Maturity

Notes Linked to the EURO STOXX 50^® Index due July 5, 2029

Estimated Value of the Notes

The principal amount of each note is $1,000. The original issue price will equal 100% of the 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 will be less than the original offering price. We estimate that the value of each note on the pricing date will be approximately $955.50, or within $30.00 of that estimate. Our estimate of the value of the notes as determined on the pricing date will be set forth in the final pricing supplement.

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 “Selected Risk Considerations—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. The range for the estimated value of the notes set forth on the cover page of this preliminary pricing supplement reflects uncertainty on the date of this preliminary pricing supplement about the inputs to Jefferies LLC’s proprietary pricing models on the pricing date.

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 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.

WFS has advised us that if it, WFA or any of their affiliates makes a secondary market in the notes at any time up to the issue date or during the 3-month period following the issue date, the secondary market price offered by it, WFA or any of their affiliates will be increased by an amount reflecting a portion of the costs associated with selling, structuring and hedging the notes that are included in their original offering price. Because this portion of the costs is not fully deducted upon issuance, WFS has advised us that any secondary market price it, WFA or any of their affiliates offers during this period will be higher than it otherwise would be after this period, as any secondary market price offered after this period will reflect the full deduction of the costs as described above. WFS has advised us that the amount of this increase in the secondary market price will decline steadily to zero over this 3-month period.

The relationship between the estimated value on the pricing date and the secondary market price of the notes

The price at which the agents or any of their respective affiliates purchase the notes in the secondary market, absent changes in market conditions, including those related to interest rates and the Market Measure, 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 a bid-offer spread that would be charged in a secondary market transaction of this type, the costs of unwinding the related hedging transactions and other factors.

The agents and/or their respective affiliates may, but are 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.

Market Linked Notes— Upside Participation to a Cap and Principal Return at Maturity

Notes Linked to the EURO STOXX 50^® Index due July 5, 2029

Investor Considerations

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

■ seek exposure to any upside performance of the Index, without exposure to any decline in the Index, by:

☐ seeking 100% exposure to the upside performance of the Index if the ending level is greater than the starting level, subject to the maximum return at maturity of at least 32.30% (to be determined on the pricing date) of the principal amount; and

☐ providing for the repayment of the principal amount at maturity regardless of the performance of the Index;

■ are willing to forgo interest payments on the notes and dividends on the securities included in the Index; and

■ are willing to hold the notes until maturity.

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

■ seek a liquid investment or are unable or unwilling to hold the notes to maturity;

■ seek certainty of receiving a positive return on their investment;

■ seek uncapped exposure to the upside performance of the Index;

■ are unwilling to purchase notes with an estimated value as of the pricing date that is lower than the original offering price and that may be as low as the lower estimated value set forth on the cover page;

■ seek current income;

■ are unwilling to accept the risk of exposure to the Index;

■ seek exposure to the Index but are unwilling to accept the risk/return trade-offs inherent in the maturity payment amount for the notes;

■ are unwilling to accept our credit risk, to obtain exposure to the Index generally, or to the exposure to the Index that the notes provide specifically; or

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

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

Selected Risk Considerations

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

Risks Relating To The Notes Generally

You May Not Receive Any Positive Return On The Notes.

You will receive a positive return on the notes only if the ending level is greater than the starting level. Because the level of the Index will be subject to market fluctuations, the ending level may be less than the starting level, in which case the maturity payment amount will only be the principal amount of your notes. Even if the ending level is greater than the starting level, the maturity payment amount may only be slightly greater than the principal amount, and your yield on the notes may be less than the yield you would earn if you bought a traditional interest-bearing debt security of ours or another issuer with a similar credit rating with the same stated maturity date.

No Periodic Interest Will Be Paid On The Notes.

No periodic payments of interest will be made on the notes.

Your Return Will Be Limited To The Maximum Return And May Be Lower Than The Return On A Direct Investment In The Index.

The opportunity to participate in the possible increases in the level of the Index through an investment in the notes will be limited because any positive return on the notes will not exceed the maximum return. Therefore, your return on the notes may be lower than the return on a direct investment in the Index. Furthermore, the effect of the upside participation rate will be progressively reduced for all ending levels exceeding the ending level at which the maximum return is reached.

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

The calculation day will be postponed if the originally scheduled calculation day is not a trading day or if the calculation agent determines that a market disruption event has occurred or is continuing on the calculation day. If such a postponement occurs, the stated maturity date will be the later of (i) the initial stated maturity date and (ii) three business days after the calculation day as postponed.

Your Notes Will Be Treated as Debt Instruments Subject to Special Rules Governing Contingent Payment Debt Instruments for U.S. Federal Income Tax Purposes

The notes will be treated as debt instruments subject to special rules governing contingent payment debt instruments for U.S. federal income tax purposes. If you are a U.S. individual or taxable entity, you generally will be required to pay taxes on ordinary income from the notes over their term based on the comparable yield for the notes, even though you will not receive any payments from us until maturity. This comparable yield is determined solely to calculate the amount on which you will be taxed prior to maturity and is neither a prediction nor a guarantee of what the actual yield will be. In addition, any gain you may recognize on the sale, exchange or maturity of the notes will be taxed as ordinary interest income. If you are a secondary purchaser of the notes, the tax consequences to you may be different. Please see “Supplemental Discussion of U.S. Federal Income Tax Consequences” below for a more detailed discussion. 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.

Foreign Account Tax Compliance Act (FATCA) Withholding May Apply to Payments on Your Notes, Including as a Result of the Failure of the Bank or Broker Through Which You Hold the Notes to Provide Information to Tax Authorities

Please see the discussion under “United States Federal Taxation—FATCA Legislation” in the accompanying prospectus supplement for more information.

Risks Relating To An Investment In Our Debt Securities, Including The Notes

The Notes Are Subject To Our Credit Risk.

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

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

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 Original Offering Price.

The difference is attributable to certain costs associated with selling, structuring and hedging the notes that are included in the original offering 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 subsidiaries 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 subsidiaries 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

PRS-8

Market Linked Notes— Upside Participation to a Cap and Principal Return at Maturity

Notes Linked to the EURO STOXX 50^® Index due July 5, 2029

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 Market Measure. 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 subsidiaries 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 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.

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 WFS, 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. 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 original offering price.

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

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

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

In addition to the derivative component factors, the value of the notes will be affected by actual or anticipated changes in our creditworthiness. You should understand that the impact of one of the factors specified above, such as a change in interest rates, may offset some or all of any change in the value of the notes attributable to another factor, such as a change in the level of the Index. Because numerous factors are expected to affect the value of the notes, changes in the level of the Index may not result in a comparable change in the value of the notes. We anticipate that the value of the notes will always be at a discount to the principal amount plus the maximum return.

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

The notes will not be listed or displayed on any securities exchange or any automated quotation system. Although the agents and/or their respective affiliates may purchase the notes from holders, they are not obligated to do so and are not required to make a market for the notes. There can be no assurance that a secondary market will develop. Because we do not expect that any market makers will participate in a secondary market for the notes, the price at which you may be able to sell your notes is likely to depend on the price, if any, at which the agents are willing to buy your notes. If a secondary market does exist, it may be limited. Accordingly, there may be a limited number of buyers if you decide to sell your notes prior to stated maturity. This may affect the price you receive upon such sale. Consequently, you should be willing to hold the notes to stated maturity.

Risks Relating To The Index

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

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

• Historical Levels Of The Index Should Not Be Taken As An Indication Of The Future Performance Of The Index During The Term Of The Notes.

• Changes That Affect The Index May Adversely Affect The Value Of The Notes And The Maturity Payment Amount.

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

• We And Our Subsidiaries Have No Affiliation With The Index Sponsor And Have Not Independently Verified Its Public Disclosure Of Information.

An Investment In The Notes Is Subject To Risks Associated With Investing In Non-U.S. Companies.

All of the stocks included in the SX5E are issued by companies incorporated outside of the United States. 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.

Risks Relating To Conflicts Of Interest

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

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

• The calculation agent is our subsidiary and may be required to make discretionary judgments that affect the return you receive on the notes. JFSI, a wholly owned subsidiary of Jefferies Financial Group Inc., will be the calculation agent for the notes. As calculation agent, JFSI will determine any values of the Index and make any other determinations necessary to calculate any payments on the notes. In making these determinations, JFSI may be required to make discretionary judgments that may adversely affect any payments on the notes. See the sections entitled “General Terms of the Notes— Certain Terms for Notes Linked to an Index—Market Disruption Events,”—Adjustments to an Index” and “—Discontinuance of an Index” in the accompanying product supplement. In making these discretionary judgments, the fact

PRS-10

Market Linked Notes— Upside Participation to a Cap and Principal Return at Maturity

Notes Linked to the EURO STOXX 50^® Index due July 5, 2029

that JFSI is our subsidiary may cause it to have economic interests that are adverse to your interests as an investor in the notes, and JFSI’s determinations as calculation agent may adversely affect your return on the notes.

• Research reports by our subsidiaries or any participating dealer or its affiliates may be inconsistent with an investment in the notes and may adversely affect the level of the Index.

• Business activities of our subsidiaries or any participating dealer or its affiliates with the companies whose securities are included in the Index may adversely affect the level of the Index.

• Hedging activities by our subsidiaries or any participating dealer or its affiliates may adversely affect the level of the Index.

• Trading activities by our subsidiaries or any participating dealer or its affiliates may adversely affect the level of the Index.

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

Hypothetical Examples and Returns

The payout profile, return table and examples below illustrate the maturity payment amount for a $1,000 principal amount note on a hypothetical offering of notes under various scenarios, with the assumptions set forth in the table below. The terms used for purposes of these hypothetical examples do not represent the actual starting level. The hypothetical starting level of 100.00 has been chosen for illustrative purposes only and does not represent the actual starting level. The actual starting level will be determined on the pricing date and will be set forth under “Terms of the Notes” above. For historical data regarding the actual closing levels of the Index, see the historical information set forth herein. The payout profile, return table and examples below assume that an investor purchases the notes for $1,000 per note. These examples are for purposes of illustration only and the values used in the examples may have been rounded for ease of analysis. The actual maturity payment amount and resulting pre-tax total rate of return will depend on the actual terms of the notes.

	Upside Participation Rate:		100%
	Hypothetical Maximum Return:		32.30% or $323.00 per note (the lowest possible maximum return that may be determined on the pricing date)

(1) The index return is equal to the percentage change from the starting level to the ending level (i.e., the ending level minus starting level, divided by starting level).

(2) The hypothetical pre-tax total rate of return is the number, expressed as a percentage, that results from comparing the maturity payment amount per note to the principal amount of $1,000.

Hypothetical Examples

Example 1. Maturity payment amount is greater than the principal amount and reflects a return that is less than the maximum return:

	EURO STOXX 50® Index
Hypothetical starting level:	100.00
Hypothetical ending level:	105.00
Hypothetical index return (ending level – starting level)/starting level:	5.00%

Because the hypothetical ending level is greater than the hypothetical starting level, the maturity payment amount per note would be equal to the principal amount of $1,000 plus a positive return equal to the lesser of:

(i)   $1,000 × index return × upside participation rate

$1,000 × 5.00% × 100.00%

= $50.00; and

(ii)  the maximum return of $323.00

On the stated maturity date you would receive $1,050.00 per note.

Example 2. Maturity payment amount is greater than the principal amount and reflects a return equal to the maximum return:

	EURO STOXX 50® Index
Hypothetical starting level:	100.00
Hypothetical ending level:	150.00
Hypothetical index return (ending level – starting level)/starting level:	50.00%

Because the hypothetical ending level is greater than the hypothetical starting level, the maturity payment amount per note would be equal to the principal amount of $1,000 plus a positive return equal to the lesser of:

(i)   $1,000 × index return × upside participation rate

$1,000 × 50.00% × 100.00%

= $1,500.00; and

(ii)  the maximum return of $323.00

On the stated maturity date you would receive $1,323.00 per note, which is the maximum maturity payment amount.

Example 3. Maturity payment amount is equal to the principal amount:

	EURO STOXX 50® Index
Hypothetical starting level:	100.00
Hypothetical ending level:	50.00
Hypothetical index return  (ending level – starting level)/starting level:	-50.00%

Because the hypothetical ending level is less than the hypothetical starting level, the maturity payment amount per note would equal the principal amount.

On the stated maturity date you would receive $1,000 per note.

This example illustrates that the notes provide for the repayment of the principal amount at maturity even in scenarios in which the level of the Index declines significantly from the starting level (subject to our credit risk).

The Index

All disclosures contained in this pricing supplement regarding the Market Measure, including, without limitation, its make-up, method of calculation, and changes in its components, have been derived from publicly available sources. The information reflects the policies of, and is subject to change by STOXX Limited, the index sponsor of the EURO STOXX 50^® Index (the “index sponsor”). The index sponsor, which licenses the copyright and all other rights to the Market Measure, has no obligation to continue to publish, and may discontinue publication of, the Market Measure. The consequences of the index sponsor discontinuing publication of the Market Measure are discussed in “General Terms of the Notes—Discontinuance of an Index” in the accompanying product supplement. None of us, the calculation agent, or Jefferies LLC accepts any responsibility for the calculation, maintenance or publication of the Market Measure or any successor index. None of us, the calculation agent, Jefferies LLC or any of our other affiliates makes any representation to you as to the future performance of the Market Measure. You should make your own investigation into the Market Measure.

The EURO STOXX 50^® Index

The SX5E was created by STOXX, which is owned by Deutsche Börse AG. Publication of the SX5E began in February 1998, based on an initial index level of 1,000 on December 31, 1991.

Index Composition and Maintenance

The SX5E is composed of 50 stocks from 11 Eurozone countries (Austria, Belgium, Finland, France, Germany, Ireland, Italy, Luxembourg, the Netherlands, Portugal and Spain) of the STOXX Europe 600 Supersector indices. The STOXX 600 Supersector indices contain the 600 largest stocks traded on the major exchanges of 18 European countries and are organized into the following 20 Supersectors: automobiles & parts; banks; basic resources; chemicals; construction & materials; consumer products & services; energy; financial services; food, beverages & tobacco; health care; industrial goods & services; insurance; media; personal care, drug & grocery stores; real estate; retailers; technology; telecommunications; travel & leisure; and utilities.

For each of the 20 EURO STOXX regional supersector indices, the stocks are ranked in terms of free-float market capitalization. The largest stocks are added to the selection list until the coverage is close to, but still less than, 60% of the free-float market capitalization of the corresponding supersector index. If the next highest-ranked stock brings the coverage closer to 60% in absolute terms, then it is also added to the selection list. All current stocks in the SX5E are then added to the selection list. All of the stocks on the selection list are then ranked in terms of free-float market capitalization to produce the final index selection list. The largest 40 stocks on the selection list are selected; the remaining 10 stocks are selected from the largest remaining current stocks ranked between 41 and 60; if the number of stocks selected is still below 50, then the largest remaining stocks are selected until there are 50 stocks. In exceptional cases, STOXX’s management board can add stocks to and remove them from the selection list.

The index components are subject to a capped maximum index weight of 10%, which is applied on a quarterly basis.

The composition of the SX5E is reviewed annually, based on the closing stock data on the last trading day in August. Changes in the composition of the SX5E are made to ensure that the SX5E includes the 50 market sector leaders from within the EURO STOXX® Index.

The free float factors for each component stock used to calculate the SX5E, as described below, are reviewed, calculated, and implemented on a quarterly basis and are fixed until the next quarterly review.

The SX5E is subject to a “fast exit rule.” The index components are monitored for any changes based on the monthly selection list ranking. A stock is deleted from the SX5E if: (a) it ranks 75 or below on the monthly selection list and (b) it has been ranked 75 or below for a consecutive period of two months in the monthly selection list. The highest-ranked stock that is not an index component will replace it. Changes will be implemented on the close of the fifth trading day of the month, and are effective the next trading day.

The SX5E is also subject to a “fast entry rule.” All stocks on the latest selection lists and initial public offering (IPO) stocks are reviewed for a fast-track addition on a quarterly basis. A stock is added, if (a) it qualifies for the latest STOXX blue-chip selection list generated end of February, May, August or November and (b) it ranks within the “lower buffer” on this selection list.

The SX5E is also reviewed on an ongoing monthly basis. Corporate actions (including initial public offerings, mergers and takeovers, spin-offs, delistings, and bankruptcy) that affect the index composition are announced immediately, implemented two trading days later and become effective on the next trading day after implementation.

Index Calculation

The SX5E is calculated with the “Laspeyres formula,” which measures the aggregate price changes in the component stocks against a fixed base quantity weight. The formula for calculating the index value can be expressed as follows:

The “free float market capitalization of the Index” is equal to the sum of the product of the price, the number of shares and the free float factor and the weighting cap factor for each component stock as of the time the SX5E is being calculated.

PRS-15

Market Linked Notes— Upside Participation to a Cap and Principal Return at Maturity

Notes Linked to the EURO STOXX 50^® Index due July 5, 2029

The SX5E is also subject to a divisor, which is adjusted to maintain the continuity of the index values across changes due to corporate actions, such as the deletion and addition of stocks, the substitution of stocks, stock dividends, and stock splits.

Historical Information

We obtained the closing levels of the EURO STOXX 50® Index in the graph below from Bloomberg L.P., without independent verification.

The following graph sets forth daily closing levels of the Index for the period from January 1, 2019 to May 28, 2026. The closing level on May 28, 2026 was 6,055.11. The historical performance of the Index should not be taken as an indication of the future performance of the Index during the term of the notes.

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.

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 security as a hedge or that is hedged against interest rate risks;

• a person that owns a security 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.

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. 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.

If you are not a United States holder, this section does not apply to you and you should refer to “— Non-U.S. Holders” below.

Your notes will be treated as debt instruments subject to special rules governing contingent payment debt instruments for U.S. federal income tax purposes. Under those rules, the amount of interest you are required to take into account for each accrual period will be determined by constructing a projected payment schedule for your 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 yield at which we would issue a noncontingent fixed rate debt instrument with terms and conditions similar to your notes (the “comparable yield”) and then determining as of the issue date a payment schedule that would produce the comparable yield. These rules will generally have the effect of requiring you to include amounts in income in respect of your notes in each year that you own the notes, even though you will not receive any payments from us until maturity.

We have determined that the comparable yield for the notes is equal to % per annum, compounded semi-annually with a projected payment at maturity of $ based on an investment of $1,000.

Based on this comparable yield, if you are an initial holder that holds a note until maturity and you pay your taxes on a calendar year basis, we have determined that you would be required to report the following amounts as ordinary income, not taking into account any positive or negative adjustments you may be required to take into account based on the actual payments on the notes, from the note each year:

PRS-18

Market Linked Notes— Upside Participation to a Cap and Principal Return at Maturity

Notes Linked to the EURO STOXX 50^® Index due July 5, 2029

Accrual Period	Interest Deemed to Accrue During Accrual Period (per $1,000 note)	Total Interest Deemed to Have Accrued from Original Issue Date (per $1,000 note) as of End of Accrual Period
July 2, 2026 through December 31, 2026
January 1, 2027 through December 31, 2027
January 1, 2028 through December 31, 2028
January 1, 2029 through July 5, 2029

You are required to use the comparable yield and projected payment schedule that we compute in determining your interest accruals in respect of your notes, unless you timely disclose and justify on your U.S. federal income tax return the use of a different comparable yield and projected payment schedule.

The comparable yield and projected payment schedule are not provided to you for any purpose other than the determination of your interest accruals in respect of your notes, and we make no representation regarding the amount of contingent payments with respect to your notes.

If you purchase your notes at a price other than their adjusted issue price determined for tax purposes, you must determine the extent to which the difference between the price you paid for your notes and their adjusted issue price is attributable to a change in expectations as to the projected payment schedule, a change in interest rates, or both, and reasonably allocate the difference accordingly. The adjusted issue price of your notes will equal your notes’ original issue price plus any interest deemed to be accrued on your notes (under the rules governing contingent payment debt instruments) as of the time you purchase your notes. The original issue price of your notes will be the first price at which a substantial amount of the notes is sold to persons other than bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers. Therefore, you may be required to make the adjustments described above even if you purchase your notes in the initial offering if you purchase your notes at a price other than the issue price.

If the adjusted issue price of your notes is greater than the price you paid for your notes, you must make positive adjustments increasing (i) the amount of interest that you would otherwise accrue and include in income each year, and (ii) the amount of ordinary income (or decreasing the amount of ordinary loss) recognized upon maturity by the amounts allocated under the previous paragraph to each of interest and the projected payment schedule; if the adjusted issue price of your notes is less than the price you paid for your notes, you must make negative adjustments, decreasing (i) the amount of interest that you must include in income each year, and (ii) the amount of ordinary income (or increasing the amount of ordinary loss) recognized upon maturity by the amounts allocated under the previous paragraph to each of interest and the projected payment schedule. Adjustments allocated to the interest amount are not made until the date the daily portion of interest accrues.

Because any Form 1099-OID that you receive will not reflect the effects of positive or negative adjustments resulting from your purchase of notes at a price other than the adjusted issue price determined for tax purposes, you are urged to consult with your tax advisor as to whether and how adjustments should be made to the amounts reported on any Form 1099-OID.

You will recognize gain or loss upon the sale, exchange or maturity of your notes in an amount equal to the difference, if any, between the cash amount you receive at such time and your adjusted basis in your notes. In general, your adjusted basis in your notes will equal the amount you paid for your notes, increased by the amount of interest you previously accrued with respect to your notes (in accordance with the comparable yield and the projected payment schedule for your notes), and increased or decreased by the amount of any positive or negative adjustment, respectively, that you are required to make if you purchase your notes at a price other than the adjusted issue price determined for tax purposes.

Any gain you recognize upon the sale, exchange or maturity of your notes will be ordinary interest income. Any loss you recognize at such time will 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 you are a noncorporate holder, you would generally be able to use such ordinary loss to offset your income only in the taxable year in which you recognize the ordinary loss and would generally not be able to carry such ordinary loss forward or back to offset income in other taxable years.

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

PRS-19

Market Linked Notes— Upside Participation to a Cap and Principal Return at Maturity

Notes Linked to the EURO STOXX 50^® Index due July 5, 2029

■ 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.

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

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 and, notwithstanding that we do not intend to treat the notes as debt for tax purposes, we or the applicable withholding agent 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.

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 amounts you receive upon the sale, exchange or maturity of your notes, could be collected via withholding. If these regulations were to apply to the notes, we or the applicable withholding agent may be required to withhold such taxes if any U.S.-source dividends are paid on any stocks included in the Index during the term of the notes. We could also require you to make certifications (e.g., an applicable Internal Revenue Service (“IRS”) Form W-8) prior to 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 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.

Under current law, while the matter is not entirely clear, individual Non-U.S. Holders, and entities whose property is potentially includible in those individuals’ gross estates for U.S. federal estate tax purposes (for example, a trust funded by such an individual and with respect to which the individual has retained certain interests or powers), should note that, absent an applicable treaty benefit, a security is likely to be treated as U.S. situs property, subject to U.S. federal estate tax. These individuals and entities should consult their own tax advisors regarding the U.S. federal estate tax consequences of investing in a security.

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.
