6 year ETF Efficiente Note OVERVIEW JPMorgan ETF Efficiente 5 Index (the "strategy") is a cross-asset strategy that aims to maximize returns per unit of risk by using portfolio optimization technology. The strategy uses the concept of the efficient frontier to select the optimum portfolio from a universe of 12 exchange-traded funds and a cash index, and aims to maximize returns while targeting a realized volatility of 5%. The strategy rebalances monthly and is non-discretionary. The Index levels incorporate an adjustment factor of 0.50% per annum which is deducted daily. Any payment on the notes is subject to the credit risk of JPMorgan Chase & Co. May be appropriate for investors requiring asset and geographical diversification and full repayment of principal at maturity, subject to the credit risk of JP Morgan Chase & Co.

[] Payment on the Notes at maturity is subject to our credit risk. Therefore the value of the Notes prior to maturity will be subject to changes in the market's view of our creditworthiness. [] The stated payout of the note from the issuer, including the repayment of principal, only applies if you hold the notes to maturity. [] The note do not have any interest or dividend payments or voting rights. [] The strategy may not be successful. It may not outperform an alternative strategy related to the ETF Constituents. [] The strategy is subject to emerging markets risk, fixed income risks, currency exchange risk, real estate risk, ETF risks, small capitalization stock risk and the uncertain legal and regulatory regimes which govern commodities future contracts. [] Changes in the value of Basket Constituents may offset each other. []The Index applies monthly rebalancing and weighting caps that may reduce your return. []The Index has a limited operating history. Hypothetical Back-tested data related to the Index do not represent actual historical data and are subject to inherent limitations. [] Upon the occurrence of a commodity hedging disruption event, the value of the additional amount will be determined by the calculation agent on the date of such event. Your payment at maturity will be based on, in part, a level of the Index prior to the Observation Date. [] Our affiliate, JPMS plc, is the index calculation agent and may adjust the Index in a way that affects its level. [] The Index may be partially uninvested. Any uninvested portion will earn no return. [] The tax consequences of the Notes may be uncertain. You should consult your tax adviser regarding the U. S. federal income tax consequences of an investment in the Notes. [] Certain built-in costs are likely to adversely affect the value of the Notes prior to maturity. The original issue price of the Notes includes the agent's commission and the estimated cost of hedging our obligations under the Notes. As a result, the price, if any, at which JPMS will be willing to purchase Notes from you in secondary market transactions, if at all, will likely be lower than the original issue price and any sale prior to the maturity date could result in a substantial loss to you. [] Lack of liquidity: JPMorgan Securities LLC, acting as agent for the Issuer (and who we refer to as JPMS), intends to offer to purchase the Notes in the secondary market but is not required to do so. The price, if any, at which JPMS will be willing to purchase Notes from you in the secondary market, if at all, may result in a significant loss of your principal. [] Many economic and market factors, such as Index volatility, time to maturity, interest rates and creditworthiness of the Issuer, will impact the value of the Notes prior to maturity. [] Potential conflicts: we and our affiliates play a variety of roles in connection with the issuance of Notes, including acting as note calculation agent and index calculation agent, and hedging our obligations under the Notes. It is possible that such hedging or other trading activities of JPMorgan or its affiliates could result in substantial returns for JPMorgan and its affiliates while the value of the Notes decline.
