How the Notes Work

Payments in Connection with Review Dates Preceding the Final Review Date

Payment at Maturity If the Notes Have Not Been Automatically Called

PS-2 | Structured Investments Auto Callable Contingent Interest Notes Linked to the Lesser Performing of the Russell 2000® Index and the S&P 500® Index

Total Contingent Interest Payments

The table below illustrates the hypothetical total Contingent Interest Payments per $1,000 principal amount note over the term of the notes based on a hypothetical Contingent Interest Rate of 8.35% per annum, depending on how many Contingent Interest Payments are made prior to automatic call or maturity. The actual Contingent Interest Rate will be provided in the pricing supplement and will be at least 8.35% per annum.

Hypothetical Payout Examples

The following examples illustrate payments on the notes linked to two hypothetical Indices, assuming a range of performances for the hypothetical Lesser Performing Index on the Review Dates. Each hypothetical payment set forth below assumes that the closing level of the Index that is not the Lesser Performing Index on each Review Date is greater than or equal to its Initial Value (and therefore its Interest Barrier and Trigger Value).

In addition, the hypothetical payments set forth below assume the following:

The hypothetical Initial Value of the Lesser Performing Index of 100.00 has been chosen for illustrative purposes only and may not represent a likely actual Initial Value of either Index.

The actual Initial Value of each Index will be the closing level of that Index on the Pricing Date and will be provided in the pricing supplement. For historical data regarding the actual closing levels of each Index, please see the historical information set forth under “The Indices” 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 first Review Date.

Because the closing level of each Index on the first Review Date is greater than or equal to its Initial Value, the notes will be automatically called for a cash payment, for each $1,000 principal amount note, of $1,020.875 (or $1,000 plus the Contingent Interest Payment applicable to the first Review Date), payable on the applicable Call Settlement Date. No further payments will be made on the notes.

PS-3 | Structured Investments Auto Callable Contingent Interest Notes Linked to the Lesser Performing of the Russell 2000® Index and the S&P 500® Index

Example 2 — Notes have NOT been automatically called, the Final Value of the Lesser Performing Index is greater than or equal to its Initial Value and a Trigger Event has occurred.

Because the notes have not been automatically called and the Final Value of the Lesser Performing Index is greater than or equal to its Initial Value (and, therefore, its Interest Barrier), even though a Trigger Event has occurred, the payment at maturity, for each $1,000 principal amount note, will be $1,020.875 (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 $1,062.625.

Example 3 — Notes have NOT been automatically called, the Final Value of the Lesser Performing Index is less than its Initial Value and a Trigger Event has NOT occurred.

Because the notes have not been automatically called, the Final Value of the Lesser Performing Index is greater than or equal to its Interest Barrier and a Trigger Event has not occurred, even though the Final Value of the Lesser Performing Index is less than its Initial Value, the payment at maturity, for each $1,000 principal amount note, will be $1,020.875 (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 $1,083.50.

Example 4 — Notes have NOT been automatically called, the Final Value of the Lesser Performing Index is less than its Initial Value and its Interest Barrier and a Trigger Event has occurred.

Because the notes have not been automatically called, the Final Value of the Lesser Performing Index is less than its Initial Value and its Interest Barrier, a Trigger Event has occurred and the Lesser Performing Index 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.

The Indices

The Russell 2000^® Index consists of the middle 2,000 companies included in the Russell 3000E^TM Index and, as a result of the index calculation methodology, consists of the smallest 2,000 companies included in the Russell 3000^® Index. The Russell 2000^® Index is designed to track the performance of the small capitalization segment of the U.S. equity market. For additional information about the Russell 2000^® Index, see “Equity Index Descriptions — The Russell Indices” in the accompanying underlying supplement.

The S&P 500^® Index consists of stocks of 500 companies selected to provide a performance benchmark for the U.S. equity markets. For additional information about the S&P 500^® Index, see “Equity Index Descriptions — The S&P U.S. Indices” in the accompanying underlying supplement.

Historical Information

The following graphs set forth the historical performance of each Index based on the weekly historical closing levels from January 4, 2019 through October 4, 2024. The closing level of the Russell 2000^® Index on October 4, 2024 was 2,212.798. The closing level of the S&P 500^® Index on October 4, 2024 was 5,751.07. We obtained the closing levels above and below from the Bloomberg Professional^® service (“Bloomberg”), without independent verification.

The historical closing levels of each Index should not be taken as an indication of future performance, and no assurance can be given as to the closing level of either Index on the Pricing Date, any Review Date or any day during the Monitoring Period. There can be no assurance that the performance of the Indices will result in the return of any of your principal amount or the payment of any interest.

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. Based on the advice of Davis Polk & Wardwell LLP, our special tax counsel, we believe that this is a reasonable treatment, but that 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.

PS-8 | Structured Investments Auto Callable Contingent Interest Notes Linked to the Lesser Performing of the Russell 2000® Index and the S&P 500® Index

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.

PS-9 | Structured Investments Auto Callable Contingent Interest Notes Linked to the Lesser Performing of the Russell 2000® Index and the S&P 500® Index

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 Indices” 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.
