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 Observation Date. The hypothetical payments set forth below assume the following: • the notes have not been redeemed early; • a Strike Value of $100.00; • a Trigger Value of $50.00 (equal to 50.00% of the hypothetical Strike Value); and • an Interest Rate of 13.05% per annum. The hypothetical Strike Value of $100.00 has been chosen for illustrative purposes only and does not represent the actual Strike Value. The actual Strike Value is the closing price of one share of the Reference Stock on the Strike Date and is specified under “Key Terms —Strike Value” in this 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 have NOT been redeemed early and the Final Value is greater than or equal to the Trigger Value.

Because the notes have not been redeemed early and the Final Value is greater than or equal to the Trigger Value, the payment at maturity, for each $1,000 principal amount note, will be $1,010.875 (or $1,000 plus the Interest Payment applicable to the Maturity Date). When added to the Interest Payments received with respect to the prior Interest Payment Dates, the total amount paid, for each $1,000 principal amount note, is $1,261.00. Example 2 — Notes have NOT been redeemed early and the Final Value is less than the Trigger Value.

Total Payment

$661.00 (-33.90% return)

Because the notes have not been redeemed early, the Final Value is less than the Trigger Value and the Stock Return is -60.00%, the payment at maturity will be $410.875 per $1,000 principal amount note, calculated as follows: $1,000 + [$1,000 × (-60.00%)] + $10.875 = $410.875 When added to the Interest Payments received with respect to the prior Interest Payment Dates, the total amount paid, for each $1,000 principal amount note, is $661.00. The hypothetical returns and hypothetical payments on the notes shown above apply only if you hold the notes for their entire term. 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. Risks Relating to the Notes Generally • 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 redeemed early 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 Strike Value. Accordingly, under these circumstances, you will lose more than 50.00% of your principal amount at maturity and could lose all of your principal amount at maturity. • 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. • 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 THE INTEREST PAYMENTS 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.

PS-5 | Structured Investments Callable Yield Notes Linked to the Common Stock of UnitedHealth Group Incorporated

• THE BENEFIT PROVIDED BY THE TRIGGER VALUE MAY TERMINATE ON THE OBSERVATION DATE — If the Final Value is less than the Trigger Value and the notes have not been redeemed early, the benefit provided by the Trigger Value will terminate and you will be fully exposed to any depreciation of the Reference Stock. • THE OPTIONAL EARLY REDEMPTION FEATURE MAY FORCE A POTENTIAL EARLY EXIT — If we elect to redeem your notes early, the term of the notes may be reduced to as short as approximately six months and you will not receive any Interest Payments after the applicable Interest Payment 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 we elect to redeem your notes 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. • THE RISK OF THE CLOSING PRICE OF ONE SHARE OF THE REFERENCE STOCK FALLING BELOW 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 Interest Rate. Risks Relating to Conflicts of Interest • 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. Risks Relating to the Estimated Value and Secondary Market Prices of the Notes • 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

PS-6 | Structured Investments Callable Yield Notes Linked to the Common Stock of UnitedHealth Group Incorporated

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. Risks Relating 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 Reference Stock All information contained herein on the Reference Stock and on UnitedHealth Group is derived from publicly available sources, without independent verification. According to its publicly available filings with the SEC, UnitedHealth Group operates an information and technology-enabled health service business serving the health care marketplace and a health benefits business. The common stock of UnitedHealth Group, par value $0.01 per share (Bloomberg ticker: UNH), is registered under the Securities Exchange Act of 1934, as amended, which we refer to as the Exchange Act, and is listed on the New York Stock Exchange, which we refer to as the relevant exchange for purposes of UnitedHealth Group in the accompanying product supplement. Information provided to or filed with the SEC by UnitedHealth Group pursuant to the Exchange Act can be located by reference to the SEC file number 001-10864, and can be accessed through www.sec.gov. We do not make any representation that these publicly available documents are accurate or complete. Historical Information The following graph sets forth the historical performance of the Reference Stock based on the weekly historical closing prices of one share of the Reference Stock from January 3, 2020 through May 16, 2025. The closing price of one share of the Reference Stock on May 19, 2025 was $315.89. We obtained the closing prices above and below from the Bloomberg Professional®service (“Bloomberg”), without independent verification. The closing prices above and below may have been adjusted by Bloomberg for corporate actions, such as stock splits, public offerings, mergers and acquisitions, spin-offs, delistings and bankruptcy. The historical closing prices of one share of the Reference Stock should not be taken as an indication of future performance, and no assurance can be given as to the closing price of one share of the Reference Stock on the Observation Date.There can be no assurance that the performance of the Reference Stock will result in the return of any of your principal amount. Tax Treatment You should review carefully the section entitled “Material U.S. Federal Income Tax Consequences” in the accompanying product supplement no. 4-I. Based on the advice of Davis Polk & Wardwell LLP, our special tax counsel, and on current market conditions, in determining our reporting responsibilities we intend to treat the notes for U.S. federal income tax purposes as units each comprising: (x) a cash-settled Put Option written by you that is terminated if an early redemption occurs and that, if not terminated, in circumstances where the payment due at maturity is less than $1,000 (excluding accrued but unpaid interest), requires you to pay us an amount equal to that difference and (y) a Deposit of $1,000 per $1,000 principal amount note to secure your potential obligation under the Put Option, as more fully described in “Material U.S. Federal Income Tax Consequences — Tax Consequences to U.S. Holders — Notes Treated as Units Each Comprising a Put Option and a Deposit” in the accompanying product supplement, and in particular in the subsection thereof entitled “—Notes with a Term of More than One Year.” By purchasing the notes, you agree (in the absence of an administrative determination or judicial ruling to the contrary) to follow this treatment and the allocation described in the following paragraph. However, 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 and adversely 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 on a number of issues, the most relevant of which for investors in the notes are the character of income or loss (including whether the Put Premium might be currently included as ordinary income) and the degree, if any, to which income realized by

PS-8 | Structured Investments Callable Yield Notes Linked to the Common Stock of UnitedHealth Group Incorporated

non-U.S. investors should be subject to withholding tax. While it is not clear whether the notes would be viewed as similar to the typical prepaid forward contract described in the notice, it is possible that any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the notes, possibly with retroactive effect. In determining our reporting responsibilities, we intend to treat a portion of each Interest Payment equal to approximately 5.14% per annum times the amount of the Deposit times the number of days in the applicable period divided by 365 as interest on the Deposit (so that the amount allocated as interest on the Deposit will vary from Interest Payment to Interest Payment depending on the number of days in the applicable period) and the remainder of each Interest Payment as Put Premium. Assuming that the treatment of the notes as units each comprising a Put Option and a Deposit is respected, amounts treated as interest on the Deposit will be taxed as ordinary income, while the Put Premium will not be taken into account prior to sale or settlement, including a settlement following an early redemption. 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. 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 all aspects of the U.S. federal income tax consequences of an investment in the notes, including possible alternative treatments and the issues presented by the 2007 notice. Purchasers who are not initial purchasers of notes at the issue price should also consult their tax advisers with respect to the tax consequences of an investment in the notes, including possible alternative treatments, as well as the allocation of the purchase price of the notes between the Deposit and the Put Option. 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 — Risks Relating to the Estimated Value and Secondary Market Prices of the Notes — 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 — Risks Relating to the Estimated Value and Secondary Market Prices of the Notes — 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 — Risks Relating to the Estimated Value and Secondary Market Prices of the Notes — 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.
