[424B2] JPMORGAN CHASE & CO Prospectus Supplement

Rhea-AI Filing Summary

JPMorgan Chase Financial Company LLC filed a preliminary pricing supplement for Auto Callable Contingent Interest Notes linked to Salesforce, Inc. (CRM), fully and unconditionally guaranteed by JPMorgan Chase & Co.

The notes pay a Contingent Interest on each Review Date only if CRM’s closing price is at least 70.00% of the Initial Value (the Interest Barrier). They are auto‑callable if CRM is at least the Initial Value on any Review Date other than the first, second and final; the earliest potential call is January 22, 2026. If not called, and the Final Value is below the 60.00% Trigger Value, principal is reduced 1% for each 1% decline from the Initial Value, up to total loss. Upside is limited to any Contingent Interest paid.

The hypothetical Contingent Interest Rate is shown at 16.00% per annum (1.33333% monthly), with the actual rate to be at least 16.00% per annum. The estimated value would be about $979.10 per $1,000 if priced today and will not be less than $900.00 per $1,000 when set. Minimum denomination is $1,000; selling commissions will not exceed $6 per $1,000. The notes are expected to price on or about October 22, 2025 and settle on or about October 27, 2025. These are unsecured obligations subject to the issuer and guarantor’s credit risk.

The information in this preliminary pricing supplement is not complete and may be changed. This preliminary pricing supplement is not an offer to sell nor does it seek an offer to buy these securities in any jurisdiction where the offer or sale is not permitted.

Hypothetical Payout Examples

The following examples illustrate payments on the notes linked to a hypothetical Reference Stock, assuming a range of performances for the hypothetical Reference Stock on the Review Dates. The hypothetical payments set forth below assume the following:

●an Initial Value of $100.00;

●an Interest Barrier of $70.00 (equal to 70.00% of the hypothetical Initial Value);

●a Trigger Value of $60.00 (equal to 60.00% of the hypothetical Initial Value); and

●a Contingent Interest Rate of 16.00% per annum (payable at a rate of 1.33333% per month).

The hypothetical Initial Value of $100.00 has been chosen for illustrative purposes only and may not represent a likely actual Initial Value.

The actual Initial Value will be the closing price of one share of the Reference Stock on the Pricing Date and will be provided in the pricing supplement. For historical data regarding the actual closing prices of one share of the Reference Stock, please see the historical information set forth under “The Reference Stock” in this pricing supplement.

Each hypothetical payment set forth below is for illustrative purposes only and may not be the actual payment applicable to a purchaser of the notes. The numbers appearing in the following examples have been rounded for ease of analysis.

Example 1 — Notes are automatically called on the third Review Date.

Date	Closing Price	Payment (per $1,000 principal amount note)
First Review Date	$105.00	$13.3333
Second Review Date	$110.00	$13.3333
Third Review Date	$110.00	$1,013.3333
	Total Payment	$1,040.00 (4.00% return)

Because the closing price of one share of the Reference Stock on the third Review Date is greater than or equal to the Initial Value, the notes will be automatically called for a cash payment, for each $1,000 principal amount note, of $1,013.3333 (or $1,000 plus the Contingent Interest Payment applicable to the third Review Date), payable on the applicable Call Settlement Date. The notes are not automatically callable before the third Review Date, even though the closing price of one share of the Reference Stock on each of the first and second Review Dates is greater than the Initial Value. When added to the Contingent Interest Payments received with respect to the prior Review Dates, the total amount paid, for each $1,000 principal amount note, is $1,040.00. No further payments will be made on the notes.

Example 2 — Notes have NOT been automatically called and the Final Value is greater than or equal to the Trigger Value and the Interest Barrier.

Date	Closing Price	Payment (per $1,000 principal amount note)
First Review Date	$95.00	$13.3333
Second Review Date	$85.00	$13.3333
Third through Twenty-Third Review Dates	Less than Interest Barrier	$0
Final Review Date	$90.00	$1,013.3333
	Total Payment	$1,040.00 (4.00% return)

Because the notes have not been automatically called and the Final Value is greater than or equal to the Trigger Value and the Interest Barrier, the payment at maturity, for each $1,000 principal amount note, will be $1,013.3333 (or $1,000 plus the Contingent Interest Payment applicable to the final Review Date). When added to the Contingent Interest Payments received with respect to the prior Review Dates, the total amount paid, for each $1,000 principal amount note, is $1,040.00.

PS-4| Structured Investments Auto Callable Contingent Interest Notes Linked to the Common Stock of Salesforce, Inc.

Example 3 — Notes have NOT been automatically called and the Final Value is less than the Interest Barrier but is greater than or equal to the Trigger Value.

Date	Closing Price	Payment (per $1,000 principal amount note)
First Review Date	$80.00	$13.3333
Second Review Date	$75.00	$13.3333
Third through Twenty-Third Review Dates	Less than Interest Barrier	$0
Final Review Date	$60.00	$1,000.00
	Total Payment	$1,026.6667 (2.66667% return)

Because the notes have not been automatically called and the Final Value is less than the Interest Barrier but is greater than or equal to the Trigger Value, the payment at maturity, for each $1,000 principal amount note, will be $1,000.00. When added to the Contingent Interest Payments received with respect to the prior Review Dates, the total amount paid, for each $1,000 principal amount note, is $1,026.6667.

Example 4 — Notes have NOT been automatically called and the Final Value is less than the Trigger Value.

Date	Closing Price	Payment (per $1,000 principal amount note)
First Review Date	$50.00	$0
Second Review Date	$55.00	$0
Third through Twenty-Third Review Dates	Less than Interest Barrier	$0
Final Review Date	$50.00	$500.00
	Total Payment	$500.00 (-50.00% return)

Because the notes have not been automatically called, the Final Value is less than the Trigger Value and the Stock Return is -50.00%, the payment at maturity will be $500.00 per $1,000 principal amount note, calculated as follows:

$1,000 + [$1,000 × (-50.00%)] = $500.00

The hypothetical returns and hypothetical payments on the notes shown above apply only if you hold the notes for their entire term or until automatically called. These hypotheticals do not reflect the fees or expenses that would be associated with any sale in the secondary market. If these fees and expenses were included, the hypothetical returns and hypothetical payments shown above would likely be lower.

Selected Risk Considerations

An investment in the notes involves significant risks. These risks are explained in more detail in the “Risk Factors” sections of the accompanying prospectus supplement and product supplement and in Annex A to the accompanying prospectus addendum.

●YOUR INVESTMENT IN THE NOTES MAY RESULT IN A LOSS —
The notes do not guarantee any return of principal. If the notes have not been automatically called and the Final Value is less than the Trigger Value, you will lose 1% of the principal amount of your notes for every 1% that the Final Value is less than the Initial Value. Accordingly, under these circumstances, you will lose more than 40.00% of your principal amount at maturity and could lose all of your principal amount at maturity.

●THE NOTES DO NOT GUARANTEE THE PAYMENT OF INTEREST AND MAY NOT PAY ANY INTEREST AT ALL —
If the notes have not been automatically called, we will make a Contingent Interest Payment with respect to a Review Date only if the closing price of one share of the Reference Stock on that Review Date is greater than or equal to the Interest Barrier. If the closing price of one share of the Reference Stock on that Review Date is less than the Interest Barrier, no Contingent Interest Payment will be made with respect to that Review Date. Accordingly, if the closing price of one share of the Reference Stock on each Review Date is less than the Interest Barrier, you will not receive any interest payments over the term of the notes.

●CREDIT RISKS OF JPMORGAN FINANCIAL AND JPMORGAN CHASE & CO. —
Investors are dependent on our and JPMorgan Chase & Co.’s ability to pay all amounts due on the notes. Any actual or potential change in our or JPMorgan Chase & Co.’s creditworthiness or credit spreads, as determined by the market for taking that credit risk, is likely to adversely affect the value of the notes. If we and JPMorgan Chase & Co. were to default on our payment obligations, you may not receive any amounts owed to you under the notes and you could lose your entire investment.

PS-5| Structured Investments Auto Callable Contingent Interest Notes Linked to the Common Stock of Salesforce, Inc.

●AS A FINANCE SUBSIDIARY, JPMORGAN FINANCIAL HAS NO INDEPENDENT OPERATIONS AND HAS LIMITED ASSETS —
As a finance subsidiary of JPMorgan Chase & Co., we have no independent operations beyond the issuance and administration of our securities and the collection of intercompany obligations. Aside from the initial capital contribution from JPMorgan Chase & Co., substantially all of our assets relate to obligations of JPMorgan Chase & Co. to make payments under loans made by us to JPMorgan Chase & Co. or under other intercompany agreements. As a result, we are dependent upon payments from JPMorgan Chase & Co. to meet our obligations under the notes. We are not a key operating subsidiary of JPMorgan Chase & Co. and in a bankruptcy or resolution of JPMorgan Chase & Co. we are not expected to have sufficient resources to meet our obligations in respect of the notes as they come due. If JPMorgan Chase & Co. does not make payments to us and we are unable to make payments on the notes, you may have to seek payment under the related guarantee by JPMorgan Chase & Co., and that guarantee will rank pari passu with all other unsecured and unsubordinated obligations of JPMorgan Chase & Co. For more information, see the accompanying prospectus addendum.

●THE APPRECIATION POTENTIAL OF THE NOTES IS LIMITED TO THE SUM OF ANY CONTINGENT INTEREST PAYMENTS THAT MAY BE PAID OVER THE TERM OF THE NOTES,
regardless of any appreciation of the Reference Stock, which may be significant. You will not participate in any appreciation of the Reference Stock.

●POTENTIAL CONFLICTS —
We and our affiliates play a variety of roles in connection with the notes. In performing these duties, our and JPMorgan Chase & Co.’s economic interests are potentially adverse to your interests as an investor in the notes. It is possible that hedging or trading activities of ours or our affiliates in connection with the notes could result in substantial returns for us or our affiliates while the value of the notes declines. Please refer to “Risk Factors — Risks Relating to Conflicts of Interest” in the accompanying product supplement.

●THE BENEFIT PROVIDED BY THE TRIGGER VALUE MAY TERMINATE ON THE FINAL REVIEW DATE—
If the Final Value is less than the Trigger Value and the notes have not been automatically called, the benefit provided by the Trigger Value will terminate and you will be fully exposed to any depreciation of the Reference Stock.

●THE AUTOMATIC CALL FEATURE MAY FORCE A POTENTIAL EARLY EXIT —
If your notes are automatically called, the term of the notes may be reduced to as short as approximately three months and you will not receive any Contingent Interest Payments after the applicable Call Settlement Date. There is no guarantee that you would be able to reinvest the proceeds from an investment in the notes at a comparable return and/or with a comparable interest rate for a similar level of risk. Even in cases where the notes are called before maturity, you are not entitled to any fees and commissions described on the front cover of this pricing supplement.

●YOU WILL NOT RECEIVE DIVIDENDS ON THE REFERENCE STOCK OR HAVE ANY RIGHTS WITH RESPECT TO THE REFERENCE STOCK.

●NO AFFILIATION WITH THE REFERENCE STOCK ISSUER —
We have not independently verified any of the information about the Reference Stock issuer contained in this pricing supplement. You should undertake your own investigation into the Reference Stock and its issuer. We are not responsible for the Reference Stock issuer’s public disclosure of information, whether contained in SEC filings or otherwise.

●THE ANTI-DILUTION PROTECTION FOR THE REFERENCE STOCK IS LIMITED AND MAY BE DISCRETIONARY —
The calculation agent will not make an adjustment in response to all events that could affect the Reference Stock. The calculation agent may make adjustments in response to events that are not described in the accompanying product supplement to account for any diluting or concentrative effect, but the calculation agent is under no obligation to do so or to consider your interests as a holder of the notes in making these determinations.

●THE RISK OF THE CLOSING PRICE OF ONE SHARE OF THE REFERENCE STOCK FALLING BELOW THE INTEREST BARRIER OR THE TRIGGER VALUE IS GREATER IF THE PRICE OF ONE SHARE OF THE REFERENCE STOCK IS VOLATILE.

●LACK OF LIQUIDITY—
The notes will not be listed on any securities exchange. Accordingly, the price at which you may be able to trade your notes is likely to depend on the price, if any, at which JPMS is willing to buy the notes. You may not be able to sell your notes. The notes are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your notes to maturity.

●THE FINAL TERMS AND VALUATION OF THE NOTES WILL BE PROVIDED IN THE PRICING SUPPLEMENT —
You should consider your potential investment in the notes based on the minimums for the estimated value of the notes and the Contingent Interest Rate.

PS-6| Structured Investments Auto Callable Contingent Interest Notes Linked to the Common Stock of Salesforce, Inc.

●THE TAX DISCLOSURE IS SUBJECT TO CONFIRMATION —
The information set forth under “Tax Treatment” in this pricing supplement remains subject to confirmation by our special tax counsel following the pricing of the notes. If that information cannot be confirmed by our tax counsel, you may be asked to accept revisions to that information in connection with your purchase. Under these circumstances, if you decline to accept revisions to that information, your purchase of the notes will be canceled.

●THE ESTIMATED VALUE OF THE NOTES WILL BE LOWER THAN THE ORIGINAL ISSUE PRICE (PRICE TO PUBLIC) OF THE NOTES —
The estimated value of the notes is only an estimate determined by reference to several factors. The original issue price of the notes will exceed the estimated value of the notes because costs associated with selling, structuring and hedging the notes are included in the original issue price of the notes. These costs include the selling commissions, the projected profits, if any, that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the notes and the estimated cost of hedging our obligations under the notes. See “The Estimated Value of the Notes” in this pricing supplement.

●THE ESTIMATED VALUE OF THE NOTES DOES NOT REPRESENT FUTURE VALUES OF THE NOTES AND MAY DIFFER FROM OTHERS’ ESTIMATES —
See “The Estimated Value of the Notes” in this pricing supplement.

●THE ESTIMATED VALUE OF THE NOTES IS DERIVED BY REFERENCE TO AN INTERNAL FUNDING RATE —
The internal funding rate used in the determination of the estimated value of the notes may differ from the market-implied funding rate for vanilla fixed income instruments of a similar maturity issued by JPMorgan Chase & Co. or its affiliates. Any difference may be based on, among other things, our and our affiliates’ view of the funding value of the notes as well as the higher issuance, operational and ongoing liability management costs of the notes in comparison to those costs for the conventional fixed income instruments of JPMorgan Chase & Co. This internal funding rate is based on certain market inputs and assumptions, which may prove to be incorrect, and is intended to approximate the prevailing market replacement funding rate for the notes. The use of an internal funding rate and any potential changes to that rate may have an adverse effect on the terms of the notes and any secondary market prices of the notes. See “The Estimated Value of the Notes” in this pricing supplement.

●THE VALUE OF THE NOTES AS PUBLISHED BY JPMS (AND WHICH MAY BE REFLECTED ON CUSTOMER ACCOUNT STATEMENTS) MAY BE HIGHER THAN THE THEN-CURRENT ESTIMATED VALUE OF THE NOTES FOR A LIMITED TIME PERIOD —
We generally expect that some of the costs included in the original issue price of the notes will be partially paid back to you in connection with any repurchases of your notes by JPMS in an amount that will decline to zero over an initial predetermined period. See “Secondary Market Prices of the Notes” in this pricing supplement for additional information relating to this initial period. Accordingly, the estimated value of your notes during this initial period may be lower than the value of the notes as published by JPMS (and which may be shown on your customer account statements).

●SECONDARY MARKET PRICES OF THE NOTES WILL LIKELY BE LOWER THAN THE ORIGINAL ISSUE PRICE OF THE NOTES —
Any secondary market prices of the notes will likely be lower than the original issue price of the notes because, among other things, secondary market prices take into account our internal secondary market funding rates for structured debt issuances and, also, because secondary market prices may exclude selling commissions, projected hedging profits, if any, and estimated hedging costs that are included in the original issue price of the notes. As a result, the price, if any, at which JPMS will be willing to buy the notes from you in secondary market transactions, if at all, is likely to be lower than the original issue price. Any sale by you prior to the Maturity Date could result in a substantial loss to you.

●SECONDARY MARKET PRICES OF THE NOTES WILL BE IMPACTED BY MANY ECONOMIC AND MARKET FACTORS —
The secondary market price of the notes during their term will be impacted by a number of economic and market factors, which may either offset or magnify each other, aside from the selling commissions, projected hedging profits, if any, estimated hedging costs and the price of one share of the Reference Stock. Additionally, independent pricing vendors and/or third party broker-dealers may publish a price for the notes, which may also be reflected on customer account statements. This price may be different (higher or lower) than the price of the notes, if any, at which JPMS may be willing to purchase your notes in the secondary market. See “Risk Factors — Risks Relating to the Estimated Value and Secondary Market Prices of the Notes — Secondary market prices of the notes will be impacted by many economic and market factors” in the accompanying product supplement.

Tax Treatment

You should review carefully the section entitled “Material U.S. Federal Income Tax Consequences” in the accompanying product supplement no. 4-I. In determining our reporting responsibilities we intend to treat (i) the notes for U.S. federal income tax purposes as prepaid forward contracts with associated contingent coupons and (ii) any Contingent Interest Payments as ordinary income, as described in the section entitled “Material U.S. Federal Income Tax Consequences — Tax Consequences to U.S. Holders — Notes Treated as Prepaid Forward Contracts with Associated Contingent Coupons” in the accompanying product supplement. We expect to ask our special tax counsel to advise us that this is a reasonable treatment, although there are other reasonable treatments that the IRS or a court may adopt, in which case the timing and character of any income or loss on the notes could be materially affected. In addition, in 2007 Treasury and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. The notice focuses in particular on whether to require investors in these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments and the relevance of factors such as the nature of the underlying property to which the instruments are linked. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially affect the tax consequences of an investment in the notes, possibly with retroactive effect. The discussions above and in the accompanying product supplement do not address the consequences to taxpayers subject to special tax accounting rules under Section 451(b) of the Code. You should consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the notes, including possible alternative treatments and the issues presented by the notice described above.

Non-U.S. Holders — Tax Considerations. The U.S. federal income tax treatment of Contingent Interest Payments is uncertain, and although we believe it is reasonable to take a position that Contingent Interest Payments are not subject to U.S. withholding tax (at least if an applicable Form W-8 is provided), it is expected that withholding agents will (and we, if we are the withholding agent, intend to) withhold on any Contingent Interest Payment paid to a Non-U.S. Holder generally at a rate of 30% or at a reduced rate specified by an applicable income tax treaty under an “other income” or similar provision. We will not be required to pay any additional amounts with respect to amounts withheld. In order to claim an exemption from, or a reduction in, the 30% withholding tax, a Non-U.S. Holder of the notes must comply with certification requirements to establish that it is not a U.S. person and is eligible for such an exemption or reduction under an applicable tax treaty. If you are a Non-U.S. Holder, you should consult your tax adviser regarding the tax treatment of the notes, including the possibility of obtaining a refund of any withholding tax and the certification requirement described above.

Section 871(m) of the Code and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% withholding tax (unless an income tax treaty applies) on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities. Section 871(m) provides certain exceptions to this withholding regime, including for instruments linked to certain broad-based indices that meet requirements set forth in the applicable Treasury regulations. Additionally, a recent IRS notice excludes from the scope of Section 871(m) instruments issued prior to January 1, 2027 that do not have a delta of one with respect to underlying securities that could pay U.S.-source dividends for U.S. federal income tax purposes (each an “Underlying Security”). Based on certain determinations made by us, we expect that Section 871(m) will not apply to the notes with regard to Non-U.S. Holders. Our determination is not binding on the IRS, and the IRS may disagree with this determination. Section 871(m) is complex and its application may depend on your particular circumstances, including whether you enter into other transactions with respect to an Underlying Security. If necessary, further information regarding the potential application of Section 871(m) will be provided in the pricing supplement for the notes. You should consult your tax adviser regarding the potential application of Section 871(m) to the notes.

In the event of any withholding on the notes, we will not be required to pay any additional amounts with respect to amounts so withheld.

The Estimated Value of the Notes

The estimated value of the notes set forth on the cover of this pricing supplement is equal to the sum of the values of the following hypothetical components: (1) a fixed-income debt component with the same maturity as the notes, valued using the internal funding rate described below, and (2) the derivative or derivatives underlying the economic terms of the notes. The estimated value of the notes does not represent a minimum price at which JPMS would be willing to buy your notes in any secondary market (if any exists) at any time. The internal funding rate used in the determination of the estimated value of the notes may differ from the market-implied funding rate for vanilla fixed income instruments of a similar maturity issued by JPMorgan Chase & Co. or its affiliates. Any difference may be based on, among other things, our and our affiliates’ view of the funding value of the notes as well as the higher issuance, operational and ongoing liability management costs of the notes in comparison to those costs for the conventional fixed income instruments of JPMorgan Chase & Co. This internal funding rate is based on certain market inputs and assumptions, which may prove to be incorrect, and is intended to approximate the prevailing market replacement funding rate for the notes. The use of an internal funding rate and any potential changes to that rate may have an adverse effect on the terms of the notes and any secondary market prices of the notes. For additional information, see “Selected Risk Considerations — The Estimated Value of the Notes Is Derived by Reference to an Internal Funding Rate” in this pricing supplement.

The value of the derivative or derivatives underlying the economic terms of the notes is derived from internal pricing models of our affiliates. These models are dependent on inputs such as the traded market prices of comparable derivative instruments and on various other inputs, some of which are market-observable, and which can include volatility, dividend rates, interest rates and other factors, as well as assumptions about future market events and/or environments. Accordingly, the estimated value of the notes is determined when the terms of the notes are set based on market conditions and other relevant factors and assumptions existing at that time.

The estimated value of the notes does not represent future values of the notes and may differ from others’ estimates. Different pricing models and assumptions could provide valuations for the notes that are greater than or less than the estimated value of the notes. In addition, market conditions and other relevant factors in the future may change, and any assumptions may prove to be incorrect. On future dates, the value of the notes could change significantly based on, among other things, changes in market conditions, our or JPMorgan Chase & Co.’s creditworthiness, interest rate movements and other relevant factors, which may impact the price, if any, at which JPMS would be willing to buy notes from you in secondary market transactions.

The estimated value of the notes will be lower than the original issue price of the notes because costs associated with selling, structuring and hedging the notes are included in the original issue price of the notes. These costs include the selling commissions paid to JPMS and other affiliated or unaffiliated dealers, the projected profits, if any, that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the notes and the estimated cost of hedging our obligations under the notes. Because hedging our obligations entails risk and may be influenced by market forces beyond our control, this hedging may result in a profit that is more or less than expected, or it may result in a loss. A portion of the profits, if any, realized in hedging our obligations under the notes may be allowed to other affiliated or unaffiliated dealers, and we or one or more of our affiliates will retain any remaining hedging profits. See “Selected Risk Considerations — The Estimated Value of the Notes Will Be Lower Than the Original Issue Price (Price to Public) of the Notes” in this pricing supplement.

Secondary Market Prices of the Notes

For information about factors that will impact any secondary market prices of the notes, see “Risk Factors — Risks Relating to the Estimated Value and Secondary Market Prices of the Notes — Secondary market prices of the notes will be impacted by many economic and market factors” in the accompanying product supplement. In addition, we generally expect that some of the costs included in the original issue price of the notes will be partially paid back to you in connection with any repurchases of your notes by JPMS in an amount that will decline to zero over an initial predetermined period. These costs can include selling commissions, projected hedging profits, if any, and, in some circumstances, estimated hedging costs and our internal secondary market funding rates for structured debt issuances. This initial predetermined time period is intended to be the shorter of six months and one-half of the stated term of the notes. The length of any such initial period reflects the structure of the notes, whether our affiliates expect to earn a profit in connection with our hedging activities, the estimated costs of hedging the notes and when these costs are incurred, as determined by our affiliates. See “Selected Risk Considerations — The Value of the Notes as Published by JPMS (and Which May Be Reflected on Customer Account Statements) May Be Higher Than the Then-Current Estimated Value of the Notes for a Limited Time Period” in this pricing supplement.

Supplemental Use of Proceeds

The notes are offered to meet investor demand for products that reflect the risk-return profile and market exposure provided by the notes. See “How the Notes Work” and “Hypothetical Payout Examples” in this pricing supplement for an illustration of the risk-return profile of the notes and “The Reference Stock” in this pricing supplement for a description of the market exposure provided by the notes.

The original issue price of the notes is equal to the estimated value of the notes plus the selling commissions paid to JPMS and other affiliated or unaffiliated dealers, plus (minus) the projected profits (losses) that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the notes, plus the estimated cost of hedging our obligations under the notes.

Additional Terms Specific to the Notes

You may revoke your offer to purchase the notes at any time prior to the time at which we accept such offer by notifying the applicable agent. We reserve the right to change the terms of, or reject any offer to purchase, the notes prior to their issuance. In the event of any changes to the terms of the notes, we will notify you and you will be asked to accept such changes in connection with your purchase. You may also choose to reject such changes, in which case we may reject your offer to purchase.

You should read this pricing supplement together with the accompanying prospectus, as supplemented by the accompanying prospectus supplement relating to our Series A medium-term notes of which these notes are a part, the accompanying prospectus addendum and the more detailed information contained in the accompanying product supplement.
