■ Linked to the S&P 500® Index (the “Index”). ■ Unlike ordinary debt securities, the securities do not pay interest and provide for a minimum payment at maturity equal to only 95% of the face amount. Instead, the securities provide for a maturity payment amount that may be greater than, equal to or less than the face amount of the securities, depending on the performance of the Index from its starting level to its ending level. The maturity payment amount will reflect the following terms: ■ If the level of the Index increases, you will receive the face amount plus a positive return equal to 100% of the percentage increase in the level of the Index from the starting level to the ending level, subject to a maximum return at maturity of 17.50% of the face amount. As a result of the maximum return, the maximum maturity payment amount is $1,175.00 ■ If the level of the Index remains unchanged, you will receive the face amount ■ If the level of the Index decreases, you will have 1-to-1 downside exposure to the first 5% decrease in the level of the Index from the starting level to the ending level and you may lose up to 5% of the face amount ■ Investors may lose up to 5% of the face amount ■ All payments on the securities are subject to our credit risk, and you will have no ability to pursue any securities included in the Index for payment; if we default on our obligations under the securities, you could lose some or all of your investment ■ No periodic interest payments or dividends ■ No exchange listing; designed to be held to maturity

We estimate that the value of each security on the pricing date is $961.00 per security. See “Estimated Value of the Securities” in this pricing supplement.

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

Principal at Risk Securities Linked to the S&P 500® Indexdue October 4, 2028

Estimated Value of the Securities

The face amount of each security is $1,000. The original issue price will equal 100% of the face amount per security. This price includes costs associated with issuing, selling, structuring and hedging the securities, which are borne by you, and, consequently, the estimated value of the securities on the pricing date is less than the original offering price. We estimate that the value of each security on the pricing date is $961.00 per security.

Valuation of the Securities

Jefferies LLC calculated the estimated value of the securities 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 securities by estimating the value of a hypothetical package of financial instruments that would replicate the payout on the securities, which consists of a fixed-income bond (the “bond component”) and one or more derivative instruments underlying the economic terms of the securities (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 securities 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 securities is a function of the terms of the securities and the inputs to Jefferies LLC’s proprietary pricing models.

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

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

The price at which the agents or any of their respective affiliates purchase the securities 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 securities and, if it once chooses to make a market, may cease doing so at any time.

Investor Considerations

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

■	seek 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 17.50% of the face amount;

■	desire to limit downside exposure to the Index through the minimum payment at maturity;

■	are willing to accept the risk that, if the ending level is less than the starting level, they will have 1-to-1 downside exposure to the first 5% decline in the level of the Index from the starting level to the ending level and may lose up to 5% of the face amount per security at maturity;

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

■	are willing to hold the securities until maturity.

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

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

■

are unwilling to accept the risk that the ending level of the Index may decrease from the starting level, in which case they will have 1-to-1 downside exposure to the first 5% decline in the level of the Index from the starting level to the ending level and may lose up to 5% of the face amount per security at maturity.

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

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

■	are unwilling to purchase securities with an estimated value as of the pricing date that is lower than the original offering price;

■	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 securities;

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

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

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

Selected Risk Considerations

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

Risks Relating To The Securities Generally

If The Ending Level Is Less Than The Starting Level, You Will Lose Some, And Possibly Up To 5%, Of The Face Amount Of Your Securities At Maturity.

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

If the ending level is less than the starting level, the maturity payment amount will be less than the face amount and you will have 1-to-1 downside exposure to the first 5% decline in the level of the Index from the starting level to the ending level and you may lose up to 5% of the face amount per security at maturity. This is the case even if the level of the Index is greater than or equal to the starting level at certain times during the term of the securities.

Even if the ending level is greater than the starting level, the maturity payment amount may only be slightly greater than the face amount, and your yield on the securities may be less than the yield you would earn if you bought a traditional interest-bearing debt security of ours or another issuer with a similar credit rating with the same stated maturity date.

No Periodic Interest Will Be Paid On The Securities.

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

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 securities will be limited because any positive return on the securities will not exceed the maximum return. Therefore, your return on the securities 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.

We Intend to Treat Your Securities as Debt Instruments Subject to Special Rules Governing Contingent Payment Debt Instruments for U.S. Federal Income Tax Purposes.

We intend to treat your securities 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 securities over their term based on the comparable yield for the securities, 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 securities will be taxed as ordinary interest income. If you are a secondary purchaser of the securities, 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 securities in your particular circumstances.

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

The Securities Are Subject To Our Credit Risk.

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

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

The Estimated Value Of The Securities On The Pricing Date, Based On 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 securities that are included in the original offering price. These costs include (i) the selling concessions paid in connection with the offering of the securities, (ii) hedging and other costs incurred by us and our subsidiaries in connection with the offering of the securities 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 securities. These costs adversely affect the economic terms of the securities because, if they were lower, the economic terms of the securities would be more favorable to you. The economic terms of the securities are also likely to be adversely affected by the use of our internal funding rate, rather than our secondary market rate, to price the securities. See “The estimated value of the securities would be lower if it were calculated based on our secondary market rate” below.

The Estimated Value Of The Securities 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 securities. Moreover, the estimated value of the securities set forth on the cover page of this pricing supplement may differ from the value that we or our subsidiaries may determine for the securities for other purposes, including for accounting purposes. You should not invest in the securities because of the estimated value of the securities. Instead, you should be willing to hold the securities to maturity irrespective of the initial estimated value.

Since the estimated value of the securities 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 Securities Would Be Lower If It Were Calculated Based On Our Secondary Market Rate.

The estimated value of the securities 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 securities. 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 securities for purposes of any purchases of the securities 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 securities, which are generally higher than the costs associated with conventional

PRS-9

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

Principal at Risk Securities Linked to the S&P 500® Indexdue October 4, 2028

debt securities, and our liquidity needs and preferences. Our internal funding rate is not the same as the interest that is payable on the securities.

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 securities prior to maturity.

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

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

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

The value of the securities prior to stated maturity will be affected by the then-current 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 securities: Index performance; interest rates; volatility of the Index; time remaining to maturity; and dividend yields on the securities included in the Index. When we refer to the “value” of your security, we mean the value you could receive for your security 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 securities 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 securities 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 securities, changes in the level of the Index may not result in a comparable change in the value of the securities. We anticipate that the value of the securities will always be at a discount to the face amount plus the maximum return.

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

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

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

Principal at Risk Securities Linked to the S&P 500® Indexdue October 4, 2028

Hypothetical Examples

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

	Hypothetical starting level:	100.00
	Hypothetical ending level:	105.00
	Hypothetical index return:	5.00%

Because the hypothetical ending level is greater than the hypothetical starting level, the maturity payment amount per security would be equal to the face 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 $175.00

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

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

	Hypothetical starting level:	100.00
	Hypothetical ending level:	150.00
	Hypothetical index return:	50.00%

(i)

$1,000 × index return × upside participation rate

$1,000 × 50.00% × 100.00%

= $1,500.00; and

(ii)

the maximum return of $175.00

On the stated maturity date you would receive $1,175.00 per security, which is the maximum maturity payment amount.

Example 3. Maturity payment amount is less than the face amount and reflects a return that is greater than the minimum payment at maturity:

	Hypothetical starting level:	100.00
	Hypothetical ending level:	97.50
	Hypothetical index return:	-2.50%

Because the hypothetical ending level is less than or equal to the hypothetical starting level, the maturity payment amount per security would equal the greater of:

(i) $1,000 + ($1,000 × index return)

$1,000 + ($1,000 × -2.50%)

= $975.00; and

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

(ii) the minimum payment at maturity of $950.00

On the stated maturity date you would receive $975.00 per security.

Example 4. Maturity payment amount is less than the principal amount and reflects a return equal to the minimum payment at maturity:

	Hypothetical starting level:	100.00
	Hypothetical ending level:	50.00
	Hypothetical index return:	-50.00%

Because the hypothetical ending level is less than or equal to the hypothetical starting level, the maturity payment amount per security would equal the greater of:

(i) $1,000 + ($1,000 × index return)

$1,000 + ($1,000 × -50.00%)

= $500.00; and

(ii) the minimum payment at maturity of $950.00

On the stated maturity date you would receive $950.00 per security.

This example illustrates that the securities provide for the repayment of 95% of the face amount at maturity even in scenarios in which the level of the Index declines significantly from the starting level to the ending level (subject to our credit risk).

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 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 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.

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

Principal at Risk Securities Linked to the S&P 500® Indexdue October 4, 2028

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 securities, 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 securities as a capital asset for tax purposes. You are a “U.S. Holder” if you are a beneficial owner of each of your securities 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 U. S. Holder, this section does not apply to you and you should refer to “— Non-U.S. Holders” below.

We intend to treat your securities 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 securities 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 securities (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 securities in each year that you own the securities, even though you will not receive any payments from us until maturity.

We have determined that the comparable yield for the securities is equal to 4.29% per annum, compounded semi-annually with a projected payment at maturity of $1,123.77 based on an investment of $1,000.

Based on this comparable yield, if you are an initial holder that holds a security 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 securities, from the security each year:

You are required to use the comparable yield and projected payment schedule that we compute in determining your interest accruals in respect of your securities, 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 securities, and we make no representation regarding the amount of contingent payments with respect to your securities.

If you purchase your securities 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 securities 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 securities will equal your securities’ original issue price plus any interest deemed to be accrued on your securities (under the rules governing contingent payment debt instruments) as of the time you purchase your securities. The original issue price of your securities will be the first price at which a substantial amount of the securities 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 securities in the initial offering if you purchase your securities at a price other than the issue price.

If the adjusted issue price of your securities is greater than the price you paid for your securities, 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 securities is less than the price you paid for your securities, 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 securities 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 securities in an amount equal to the difference, if any, between the cash amount you receive at such time and your adjusted basis in your securities. In general, your adjusted basis in your securities will equal the amount you paid for your securities, increased by the amount of interest you previously accrued with respect to your securities (in accordance with the comparable yield and the projected payment schedule for your securities), and increased or decreased by the amount of any positive or negative adjustment, respectively, that you are required to make if you purchase your securities 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 securities 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 securities, 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.

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

Principal at Risk Securities Linked to the S&P 500® Indexdue October 4, 2028

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 securities 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 securities.

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 securities 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 securities.

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 securities and, notwithstanding that we do not intend to treat the securities as debt for tax purposes, we intend to backup withhold on such payments with respect to your securities 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 securities, could be collected via withholding. If these regulations were to apply to the securities, we may be required to withhold such taxes if any U.S.-source dividends are paid on the stocks included in the Index during the term of the securities. 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 securities 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 securities, your securities 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 securities 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 securities.

FAQ

What type of security is Jefferies (JEF) offering in this 424B2?

Jefferies is offering equity index linked, principal-at-risk medium-term notes tied to the S&P 500® Index. The notes pay no periodic interest and repay an amount at maturity based on index performance, with partial downside protection and a capped upside.

How is the maturity payment on the Jefferies S&P 500 linked notes calculated?

At maturity, each $1,000 note pays: if the S&P 500® ending level is above 6,905.74 (the starting level), $1,000 plus the lesser of 100% of the index gain or a 17.50% maximum return (capped at $1,175). If the ending level is at or below the starting level, the payment is the greater of $1,000 plus index return or the $950 minimum.

What are the main risks of these Jefferies S&P 500 index linked notes?

Key risks include principal risk up to 5% at maturity if the index declines, no interest payments, and a 17.50% cap on upside, which can limit returns versus a direct index investment. All payments depend on Jefferies’ creditworthiness, and the notes are not FDIC insured.

What are the offering price, fees and net proceeds to Jefferies for these notes?

The original offering price is $1,000 per note. Agents receive a discount of $25.75 per note, so Jefferies’ proceeds are $974.25 per note, or $529,017.75 in total on a $543,000 offering. Jefferies estimates each note’s value on the pricing date at $961.

Are the Jefferies S&P 500 linked notes liquid or exchange listed?

The notes will not be listed on any securities exchange. Jefferies’ agents or affiliates may, but are not required to, make a secondary market. Any secondary market price may be below the $1,000 offering price and will reflect bid‑ask spreads, hedging costs and Jefferies’ secondary market credit spread.

How are these Jefferies S&P 500 linked notes expected to be taxed for U.S. Holders?

Jefferies intends to treat the notes as contingent payment debt instruments for U.S. federal income tax purposes. Based on a 4.29% comparable yield, holders generally must include ordinary income each year (e.g., $42.96 in 2026 per $1,000 note) even though cash is only received at maturity.

What key dates apply to the Jefferies S&P 500 linked notes?

The pricing date is December 29, 2025, the issue date is January 2, 2026, the calculation day is September 29, 2028 (subject to postponement), and the stated maturity date is October 4, 2028, also subject to adjustment for market disruption events and non‑business days.
