Automatic Call:

If the closing price of one share of each Reference Stock on any Review Date is greater than or equal to its applicable Call Value, the notes will be automatically called for a cash payment, for each $1,000 principal amount note, equal to (a) $1,000 plus (b) the Interest Payment for the Interest Payment Date occurring on the applicable Call Settlement Date, payable on that Call Settlement Date. No further payments will be made on the notes.

If the notes have not been automatically called and the Final Value of each Reference Stock is greater than or equal to its Trigger Value, you will receive a cash payment at maturity, for each $1,000 principal amount note, equal to (a) $1,000 plus (b) the Interest Payment applicable to the Maturity Date.

If the notes have not been automatically called and the Final Value of any Reference Stock is less than its Trigger Value, your payment at maturity per $1,000 principal amount note, in addition to the Interest Payment applicable to the Maturity Date, will be calculated as follows:

$1,000 + ($1,000 × Least Performing Stock Return)

If the notes have not been automatically called and the Final Value of any Reference Stock is less than its Trigger Value, you will lose more than 50.00% of your principal amount at maturity and could lose all of your principal amount at maturity.

Least Performing Reference Stock: The Reference Stock with the Least Performing Stock Return

Least Performing Stock Return: The lowest of the Stock Returns of the Reference Stocks

Stock Return: With respect to each Reference Stock,

(Final Value – Strike Value)
Strike Value

Strike Value: With respect to each Reference Stock, the closing price of one share of that Reference Stock on the Strike Date, as specified under “Key Terms Relating to the Reference Stocks” in this pricing supplement.

Hypothetical Payout Examples

The following examples illustrate payments on the notes linked to three hypothetical Reference Stocks, assuming a range of performances for the hypothetical Least Performing Reference Stock on the Review Dates. Each hypothetical payment set forth below assumes that the closing price of one share of the Reference Stocks that are not the Least Performing Reference Stock on each Review Date is greater than or equal to its applicable Call Value.

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

· a Strike Value for the Least Performing Reference Stock of $100.00;

· the Call Values are equal to the Call Values set forth under “Key Terms — Call Value” above;

· a Trigger Value for the Least Performing Reference Stock of $50.00 (equal to 50.00% of its hypothetical Strike Value); and

· an Interest Rate of 7.25% per annum (payable at a rate of 0.60417% per month).

The hypothetical Strike Value of the Least Performing Reference Stock of $100.00 has been chosen for illustrative purposes only and does not represent the actual Strike Value of any Reference Stock. The actual Strike Value of each Reference Stock is the closing price of one share of that Reference Stock on the Strike Date and is specified under “Key Terms Relating to the Reference Stocks” in this pricing supplement. For historical data regarding the actual closing prices of one share of each Reference Stock, please see the historical information set forth under “The Reference Stocks” 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.

Date	Closing Price of One Share of Least Performing Reference Stock
First Review Date	$105.00	Notes are automatically called
	Total Payment	$1,024.1667 (2.41667% return)

Because the closing price of one share of each Reference Stock on the first Review Date is greater than or equal to its applicable Call Value, the notes will be automatically called for a cash payment, for each $1,000 principal amount note, of $1,006.0417 (or $1,000 plus the Interest Payment applicable to the corresponding Interest Payment Date), payable on the applicable Call Settlement 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 $1,024.1667.  No further payments will be made on the notes.

PS-3 | Structured Investments Auto Callable Yield Notes Linked to the Least Performing of the Common Stock of The Coca-Cola Company, the Class B Common Stock of NIKE, Inc. and the Common Stock of NVIDIA Corporation

Example 2 — Notes are automatically called on the eighth Review Date.

Date	Closing Price of One Share of Least Performing Reference Stock
First Review Date	$95.00	Notes NOT automatically called
Second through Seventh Review Dates	Less than applicable Call Value	Notes NOT automatically called
Eighth Review Date	$90.00	Notes are automatically called
	Total Payment	$1,066.4583 (6.64583% return)

Because the closing price of one share of each Reference Stock on the eighth Review Date is greater than or equal to its applicable Call Value, the notes will be automatically called for a cash payment, for each $1,000 principal amount note, of $1,006.0417 (or $1,000 plus the Interest Payment applicable to the corresponding Interest Payment Date), payable on the applicable Call Settlement 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 $1,066.4583.  No further payments will be made on the notes.

Example 3 — Notes are automatically called on the final Review Date.

Date	Final Value of the Least Performing Reference Stock
First Review Date	$85.00	Notes NOT automatically called
Second through Fourteenth Review Dates	Less than applicable Call Value	Notes NOT automatically called
Final Review Date	$90.00	Notes are automatically called
	Total Payment	$1,108.75 (10.875% return)

Because the closing price of one share of each Reference Stock on the final Review Date (i.e., its Final Value) is greater than or equal to its applicable Call Value, the notes will be automatically called for a cash payment, for each $1,000 principal amount note, of $1,006.0417 (or $1,000 plus the Interest Payment applicable to the corresponding Interest Payment Date), payable on the applicable Call Settlement Date (i.e., 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 $1,108.75. 

Example 4 — Notes have NOT been automatically called and the Final Value of the Least Performing Reference Stock is greater than or equal to its Trigger Value.

Date	Final Value of the Least Performing Reference Stock
First Review Date	$90.00	Notes NOT automatically called
Second through Fourteenth Review Dates	Less than applicable Call Value	Notes NOT automatically called
Final Review Date	$80.00	Notes NOT automatically called; Final Value of the Least Performing Reference Stock is greater than or equal to its Trigger Value
	Total Payment	$1,108.75 (10.875% return)

Because the notes have not been automatically called and the Final Value of the Least Performing Reference Stock is greater than or equal to its Trigger Value, the payment at maturity, for each $1,000 principal amount note, will be $1,006.0417 (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 $1,108.75.

PS-4 | Structured Investments Auto Callable Yield Notes Linked to the Least Performing of the Common Stock of The Coca-Cola Company, the Class B Common Stock of NIKE, Inc. and the Common Stock of NVIDIA Corporation

Example 5 — Notes have NOT been automatically called and the Final Value of the Least Performing Reference Stock is less than its Trigger Value.

Date	Final Value of the Least Performing Reference Stock
First Review Date	$80.00	Notes NOT automatically called
Second through Fourteenth Review Dates	Less than applicable Call Value	Notes NOT automatically called
Final Review Date	$40.00	Notes NOT automatically called; Final Value of the Least Performing Reference Stock is less than its Trigger Value
	Total Payment	$508.75 (-49.125% return)

Because the notes have not been automatically called, the Final Value of the Least Performing Reference Stock is less than its Trigger Value and the Least Performing Reference Stock Return is -60.00%, the payment at maturity will be $406.0417 per $1,000 principal amount note, calculated as follows:

$1,000 + [$1,000 × (-60.00%)] + $6.0417 = $406.0417

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 $508.75.

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” section of the accompanying product supplement.

· 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 of any Reference Stock is less than its Trigger Value, you will lose 1% of the principal amount of your notes for every 1% that the Final Value of the Least Performing Reference Stock is less than its 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. Aside from the initial capital contribution from JPMorgan Chase & Co., substantially all of our assets relate to obligations of our affiliates to make payments under loans made by us or other intercompany agreements. As a result, we are dependent upon payments from our affiliates to meet our obligations under the notes. If these affiliates do not make payments to us and we fail 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.

· 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 any Reference Stock, which may be significant. You will not participate in any appreciation of any Reference Stock.

PS-5 | Structured Investments Auto Callable Yield Notes Linked to the Least Performing of the Common Stock of The Coca-Cola Company, the Class B Common Stock of NIKE, Inc. and the Common Stock of NVIDIA Corporation

· 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.

· YOU ARE EXPOSED TO THE RISK OF DECLINE IN THE VALUE OF EACH REFERENCE STOCK —

Payments on the notes are not linked to a basket composed of the Reference Stocks and are contingent upon the performance of each individual Reference Stock. Poor performance by any of the Reference Stocks over the term of the notes may result in the notes not being automatically called on a Review Date, may negatively affect your payment at maturity and will not be offset or mitigated by positive performance by any other Reference Stock.

· YOUR PAYMENT AT MATURITY WILL BE DETERMINED BY THE LEAST PERFORMING 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 four months and you will not receive any 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.

· THE BENEFIT PROVIDED BY THE TRIGGER VALUE MAY TERMINATE ON THE FINAL REVIEW DATE —

If the Final Value of any Reference Stock is less than its 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 Least Performing Reference Stock.

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

· NO AFFILIATION WITH ANY REFERENCE STOCK ISSUER —

We have not independently verified any of the information about any Reference Stock issuer contained in this pricing supplement. You should undertake your own investigation into each Reference Stock and its issuer. We are not responsible for any Reference Stock issuer’s public disclosure of information, whether contained in SEC filings or otherwise.

· THE ANTI-DILUTION PROTECTION FOR THE REFERENCE STOCKS IS LIMITED AND MAY BE DISCRETIONARY —

The calculation agent will not make an adjustment in response to all events that could affect a 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 A REFERENCE STOCK FALLING BELOW ITS TRIGGER VALUE IS GREATER IF THE PRICE OF ONE SHARE OF THAT 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.

PS-6 | Structured Investments Auto Callable Yield Notes Linked to the Least Performing of the Common Stock of The Coca-Cola Company, the Class B Common Stock of NIKE, Inc. and the Common Stock of NVIDIA Corporation

· 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 is 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-rate debt of JPMorgan Chase & Co.. 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 (a) exclude selling commissions and (b) may exclude 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 each 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. 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 automatic call occurs and that, if not terminated, in circumstances where the payment due at maturity is less than the principal amount (excluding accrued but unpaid interest), requires you to pay us an amount equal to the principal amount multiplied by the absolute value of the Least Performing Stock Return 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 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 2.60% 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 (such an index, a “Qualified Index”).  Additionally, a recent IRS notice excludes from the scope of Section 871(m) instruments issued prior to January 1, 2019 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.

Withholding under legislation commonly referred to as “FATCA” will apply to amounts treated as interest or other “fixed or determinable annual or periodical” income (“FDAP Income”) for U.S. federal income tax purposes paid with respect to the notes, and (if they are treated, in whole or in part, as debt instruments) could also apply to payments of gross proceeds of a taxable disposition, including an early redemption or redemption at maturity, of a note. However, under a recent IRS notice, this regime will not apply to payments of gross proceeds (other than any amount treated as FDAP Income) with respect to dispositions occurring before January 1, 2019. You should consult your tax adviser regarding the potential application of FATCA 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 is 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-rate debt of JPMorgan Chase & Co. 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

PS-10 | Structured Investments Auto Callable Yield Notes Linked to the Least Performing of the Common Stock of The Coca-Cola Company, the Class B Common Stock of NIKE, Inc. and the Common Stock of NVIDIA Corporation

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 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 Stocks” 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.

Supplemental Plan of Distribution

We expect that delivery of the notes will be made against payment for the notes on or about the Original Issue Date set forth on the front cover of this pricing supplement, which will be the fifth business day following the Pricing Date of the notes (this settlement cycle being referred to as “T+5”). Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two business days, unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on any date prior to two business days before delivery will be required to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisors.

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”).  For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a

PS-11 | Structured Investments Auto Callable Yield Notes Linked to the Least Performing of the Common Stock of The Coca-Cola Company, the Class B Common Stock of NIKE, Inc. and the Common Stock of NVIDIA Corporation

customer within the meaning of Directive 2002/92/EC (as amended, the “Insurance Mediation Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Directive 2003/71/EC (as amended, the “Prospectus Directive”).  Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

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.

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.
