Supplemental Terms of the Notes The notes are not commodity futures contracts or swaps and are not regulated under the Commodity Exchange Act of 1936, as amended (the “Commodity Exchange Act”). The notes are offered pursuant to an exemption from regulation under the Commodity Exchange Act, commonly known as the hybrid instrument exemption, that is available to securities that have one or more payments indexed to the value, level or rate of one or more commodities, as set out in section 2(f) of that statute. Accordingly, you are not afforded any protection provided by the Commodity Exchange Act or any regulation promulgated by the Commodity Futures Trading Commission. Any values of the Index, and any values derived therefrom, included in this pricing supplement may be corrected, in the event of manifest error or inconsistency, by amendment of this pricing supplement and the corresponding terms of the notes. Notwithstanding anything to the contrary in the indenture governing the notes, that amendment will become effective without consent of the holders of the notes or any other party.

Hypothetical Payout Profile The following table and graph illustrate the hypothetical total return and payment at maturity on the notes linked to a hypothetical Index. The “total return” as used in this pricing supplement is the number, expressed as a percentage, that results from comparing the payment at maturity per $1,000 principal amount note to $1,000. The hypothetical total returns and payments set forth below assume the following: • an Initial Value of 100.00; • an Upside Leverage Factor of 1.58; and • a Barrier Amount of 70.00 (equal to 70.00% of the hypothetical Initial Value). 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 level of the Index on the Pricing Date and will be provided in the pricing supplement. For historical data regarding the actual closing levels of the Index, please see the historical information set forth under “The Index” in this pricing supplement. Each hypothetical total return or hypothetical payment at maturity set forth below is for illustrative purposes only and may not be the actual total return or payment at maturity applicable to a purchaser of the notes. The numbers appearing in the following table and graph have been rounded for ease of analysis.

The following graph demonstrates the hypothetical payments at maturity on the notes for a range of Index Returns. There can be no assurance that the performance of the Index will result in the return of any of your principal amount. How the Notes Work Upside Scenario: If the Final Value is greater than the Initial Value, investors will receive at maturity the $1,000 principal amount plus a return equal to the Index Return times the Upside Leverage Factor of at least 1.58. • Assuming a hypothetical Upside Leverage Factorof 1.58, if the closing level of the Index increases 10.00%, investors will receive at maturity a return equal to 15.80%, or $1,158.00 per $1,000 principal amount note. Par Scenario: If the Final Value is equal to the Initial Value or is less than the Initial Value but greater than or equal to the Barrier Amount of 70.00% of the Initial Value, investors will receive at maturity the principal amount of their notes. Downside Scenario: If the Final Value is less than the Barrier Amount of 70.00% of the Initial Value, investors will lose 1% of the principal amount of their notes for every 1% that the Final Value is less than the Initial Value.In no event, however, will the payment at maturity be less than $0. • For example, if the closing level of the Index declines 60.00%, investors will lose 60.00% of their principal amount and receive only $400.00 per $1,000 principal amount note at maturity. 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 Final Value is less than the Barrier Amount, you will lose 1% of the principal amount of your notes for every 1% that the Final Value is less than the Initial Value. In no event, however, will the payment at maturity be less than $0. Accordingly, under these circumstances, you will lose more than 30.00% of your principal amount at maturity and could lose all of your principal amount at maturity.

PS-5 | Structured Investments Uncapped Accelerated Barrier Notes Linked to the Bloomberg Commodity IndexSM

• 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 BENEFIT PROVIDED BY THE BARRIER AMOUNT MAY TERMINATE ON THE OBSERVATION DATE— If the Final Value is less than the Barrier Amount, the benefit provided by the Barrier Amount will terminate and you will be fully exposed to any depreciation of the Index. • THE NOTES DO NOT PAY INTEREST. • YOU WILL NOT HAVE ANY RIGHTS WITH RESPECT TO THE COMMODITY FUTURE CONTRACTS UNDERLYING THE INDEX. • THE RISK OF THE CLOSING LEVEL OF THE INDEX FALLING BELOW THE BARRIER AMOUNT IS GREATER IF THE LEVEL OF THE INDEX IS VOLATILE. • WE MAY ACCELERATE YOUR NOTES IF A COMMODITY HEDGING DISRUPTION EVENT OCCURS — If we or our affiliates are unable to effect transactions necessary to hedge our obligations under the notes due to a commodity hedging disruption event, we may, in our sole and absolute discretion, accelerate the payment on your notes and pay you an amount determined in good faith and in a commercially reasonable manner by the calculation agent. If the payment on your notes is accelerated, your investment may result in a loss and you may not be able to reinvest your money in a comparable investment. Please see “General Terms of Notes — Consequences of a Commodity Hedging Disruption Event —Acceleration of the Notes” in the accompanying product supplement for more information. • 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 Upside Leverage Factor. 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.

PS-6 | Structured Investments Uncapped Accelerated Barrier Notes Linked to the Bloomberg Commodity IndexSM

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 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 level of the Index. 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 Index • COMMODITY FUTURES CONTRACTS ARE SUBJECT TO UNCERTAIN LEGAL AND REGULATORY REGIMES — The commodity futures contracts that underlie the Index are subject to legal and regulatory regimes that may change in ways that could adversely affect our ability to hedge our obligations under the notes and affect the level of the Index. Any future regulatory changes may have a substantial adverse effect on the value of your notes. Additionally, in October 2020, the U.S. Commodity

PS-7 | Structured Investments Uncapped Accelerated Barrier Notes Linked to the Bloomberg Commodity IndexSM

Futures Trading Commission adopted rules to establish revised or new position limits on 25 agricultural, metals and energy commodity derivatives contracts. The limits apply to a person’s combined position in the specified 25 futures contracts and options on futures (“core referenced futures contracts”), futures and options on futures directly or indirectly linked to the core referenced futures contracts, and economically equivalent swaps.These rules came into effect on January 1, 2022 for covered futures and options on futures contracts and on January 1, 2023 for covered swaps. The rules may reduce liquidity in the exchange-traded market for those commodity-based futures contracts, which may, in turn, have an adverse effect on any payments on the notes. Furthermore, we or our affiliates may be unable as a result of those restrictions to effect transactions necessary to hedge our obligations under the notes resulting in a commodity hedging disruption event, in which case we may, in our sole and absolute discretion, accelerate the payment on your notes. See “— Risks Relating to the Notes Generally — We May Accelerate Your Notes If a Commodity Hedging Disruption Event Occurs” above. • PRICES OF COMMODITY FUTURES CONTRACTS ARE CHARACTERIZED BY HIGH AND UNPREDICTABLE VOLATILITY, WHICH COULD LEAD TO HIGH AND UNPREDICTABLE VOLATILITY IN THE INDEX — Market prices of the commodity futures contracts included in the Index tend to be highly volatile and may fluctuate rapidly based on numerous factors, including changes in supply and demand relationships, governmental programs and policies, national and international monetary, trade, political and economic events, wars and acts of terror, changes in interest and exchange rates, speculation and trading activities in commodities and related contracts, weather, and agricultural, trade, fiscal and exchange control policies. The prices of commodities and commodity futures contracts are subject to variables that may be less significant to the values of traditional securities, such as stocks and bonds. These variables may create additional investment risks that cause the value of the notes to be more volatile than the values of traditional securities. As a general matter, the risk of low liquidity or volatile pricing around the maturity date of a commodity futures contract is greater than in the case of other futures contracts because (among other factors) a number of market participants take physical delivery of the underlying commodities. Many commodities are also highly cyclical. The high volatility and cyclical nature of commodity markets may render such an investment inappropriate as the focus of an investment portfolio. • A DECISION BY AN EXCHANGE ON WHICH THE COMMODITY FUTURES CONTRACTS UNDERLYING THE INDEX ARE TRADED TO INCREASE MARGIN REQUIREMENTS FOR THOSE FUTURES CONTRACTS MAY AFFECT THE LEVEL OF THE INDEX — If an exchange on which the commodity futures contracts underlying the Index are traded increases the amount of collateral required to be posted to hold positions in those futures contracts (i.e., the margin requirements), market participants who are unwilling or unable to post additional collateral may liquidate their positions, which may cause the level of the Index to decline significantly. • THE NOTES DO NOT OFFER DIRECT EXPOSURE TO COMMODITY SPOT PRICES — The notes are linked to the Index, which tracks commodity futures contracts, not physical commodities (or their spot prices). The price of a futures contract reflects the expected value of the commodity upon delivery in the future, whereas the spot price of a commodity reflects the immediate delivery value of the commodity. A variety of factors can lead to a disparity between the expected future price of a commodity and the spot price at a given point in time, such as the cost of storing the commodity for the term of the futures contract, interest charges incurred to finance the purchase of the commodity and expectations concerning supply and demand for the commodity. The price movements of a futures contract are typically correlated with the movements of the spot price of the referenced commodity, but the correlation is generally imperfect and price movements in the spot market may not be reflected in the futures market (and vice versa). Accordingly, the notes may underperform a similar investment that is linked to commodity spot prices. • HIGHER FUTURES PRICES OF THE COMMODITY FUTURES CONTRACTS UNDERLYING THE INDEX RELATIVE TO THE CURRENT PRICES OF THOSE CONTRACTS MAY AFFECT THE LEVEL OF THE INDEX AND THE VALUE OF THE NOTES — The Index is composed of futures contracts on physical commodities. Unlike equities, which typically entitle the holder to a continuing stake in a corporation, commodity futures contracts normally specify a certain date for delivery of the underlying physical commodity. As the exchange-traded futures contracts that compose the Index approach expiration, they are replaced by contracts that have a later expiration. Thus, for example, a contract purchased and held in August may specify an October expiration. As time passes, the contract expiring in October is replaced with a contract for delivery in November. This process is referred to as “rolling.” If the market for these contracts is (putting aside other considerations) in “contango,” where the prices are higher in the distant delivery months than in the nearer delivery months, the purchase of the November contract would take place at a price that is higher than the price of the October contract, thereby creating a negative “roll yield.” Contango could adversely affect the level of the Index and thus the value of notes linked to the Index. The futures contracts underlying the Index have historically been in contango.

PS-8 | Structured Investments Uncapped Accelerated Barrier Notes Linked to the Bloomberg Commodity IndexSM

• SUSPENSION OR DISRUPTIONS OF MARKET TRADING IN THE COMMODITY MARKETS AND RELATED FUTURES MARKETS MAY ADVERSELY AFFECT THE LEVEL OF THE INDEX AND, THEREFORE, THE VALUE OF THE NOTES — The commodity markets are subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets, the participation of speculators and government regulation and intervention. In addition, U.S. futures exchanges and some foreign exchanges have regulations that limit the amount of fluctuation in futures contract prices that may occur during a single day. These limits are generally referred to as “daily price fluctuation limits” and the maximum or minimum price of a contract on any given day as a result of these limits is referred to as a “limit price.” Once the limit price has been reached in a particular contract, no trades may be made at a different price. Limit prices have the effect of precluding trading in a particular contract or forcing the liquidation of contracts at disadvantageous times or prices. These circumstances could adversely affect the level of the Index and, therefore, the value of your notes. • THE NOTES ARE LINKED TO AN EXCESS RETURN INDEX AND NOT A TOTAL RETURN INDEX — The notes are linked to an excess return index and not a total return index. An excess return index, such as the Index, reflects the returns that are potentially available through an unleveraged investment in the contracts composing that index. By contrast, a “total return” index, in addition to reflecting those returns, also reflects interest that could be earned on funds committed to the trading of the underlying futures contracts.

PS-9 | Structured Investments Uncapped Accelerated Barrier Notes Linked to the Bloomberg Commodity IndexSM

The Index The Index is composed of exchange-traded futures contracts on physical commodities and is designed to be a diversified benchmark for commodities as an asset class. Its component weightings are determined primarily based on liquidity data, which is the relative amount of trading activity of a particular commodity. The Index is an excess return index and not a total return index. An excess return index reflects the returns that are potentially available through an unleveraged investment in the contracts composing the index. By contrast, a “total return” index, in addition to reflecting those returns, also reflects interest that could be earned on funds committed to the trading of the underlying futures contracts. For additional information about the Index, see “Commodity Index Descriptions — The Bloomberg Commodity Indices” in the accompanying underlying supplement. Historical Information The following graph sets forth the historical performance of the Index based on the weekly historical closing levels of the Index from January 3, 2020 through July 25, 2025. The closing level of the Index on July 30, 2025 was 103.25. We obtained the closing levels above and below from the Bloomberg Professional® service (“Bloomberg”), without independent verification. The historical closing levels of the Index should not be taken as an indication of future performance, and no assurance can be given as to the closing level of the Index on the Pricing Date or the Observation Date.There can be no assurance that the performance of the Index 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. 2-I. The following discussion, when read in combination with that section, constitutes the full opinion of our special tax counsel, Davis Polk & Wardwell LLP, regarding the material U.S. federal income tax consequences of owning and disposing of notes. Based on current market conditions, in the opinion of our special tax counsel it is reasonable to treat the notes as “open transactions” that are not debt instruments for U.S. federal income tax purposes, as more fully described in “Material U.S. Federal Income Tax Consequences — Tax Consequences to U.S. Holders — Notes Treated as Open Transactions That Are Not Debt Instruments” in the accompanying product supplement. Assuming this treatment is respected, the gain or loss on your notes should be treated as long- term capital gain or loss if you hold your notes for more than a year, whether or not you are an initial purchaser of notes at the issue price. However, the IRS or a court may not respect this treatment, 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 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; the relevance of factors such as the nature of the underlying property to which the instruments are linked; the degree, if any, to which income (including any mandated accruals) realized by non-U.S. investors should be subject to withholding tax; and whether these instruments are or should be subject to the “constructive ownership” regime, which very generally can operate to recharacterize certain long-term capital gain as ordinary income and impose a notional interest charge. While the notice requests comments on appropriate transition rules and effective dates,

PS-10 | Structured Investments Uncapped Accelerated Barrier Notes Linked to the Bloomberg Commodity IndexSM

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. 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 this notice. 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, 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.
