JUNE 2024 | J . P . Mo r g an T otal R eturn SM Ind e x S electe d Risks Our affiliate, J.P. Morgan Securities LLC (“JPMS”), is the Index Sponsor and may adjust the Index in a way that affects its level. The policies and judgments for which JPMS is responsible could have an impact, positive or negative, on the level of the Index and the value of your investment. JPMS is under no obligation to consider your interest as an investor with returns linked to the Index. The Index was established on July 13, 2017, and has a limited operating history. There are risks associated with a momentum - based investment strategy. If market conditions do not represent a continuation of prior observed trends, Index performance may be adversely impacted. The Index comprises notional assets and liabilities. There is no actual portfolio of assets to which any person is entitled or in which any person has any ownership interest. The Index may not be successful, may not outperform any alternative strategy and may not maintain volatility below its historical volatility threshold of 5%. The investment strategy used to construct the Index involves monthly rebalancing and weighting constraints that are applied to the Basket Constituents, which may adversely impact performance. Changes in the values of the Basket Constituents may offset each other. There are risks associated with correlation between the Basket Constituents. If the performances of the Basket Constituents become highly correlated during periods of negative performance, Index performance may be adversely impacted. Each Basket Constituent composing the Index may be replaced by a substitute constituent upon the occurrence of certain extraordinary events. The Index should not be compared to any other index or strategy sponsored by any of our affiliates and cannot necessarily be considered a revised, enhanced or modified version of any other J . P . Mo r g an ind e x. The securities of our parent company, JPMorgan Chase & Co., are held by several of the Basket Constituents. The performance of an ETF, particularly during periods of market volatility, may not correlate with the performance of its reference index. The Index is subject to significant risks associated with fixed - income securities (including interest rate - related risks and credit risk), high - yield and investment - grade fixed - income securities (including credit risk), floating rate notes, mortgage - backed securities, preferred stock, hybrid securities, U . S . treasury inflation - protected securities and non - U . S . securities markets, including emerging markets . Investments linked to the index may be subject to the credit risk of JPMorgan Chase Bank, N . A . The risks identified above are not exhaustive. You should also review carefully the related “Risk Factors” section in the relevant disclosure statement and underlying supplement and the “Selected Risk Considerations” in the relevant term sheet or disclosure supplement. Disclaimer The information contained in this document is for discussion purposes only . Any information relating to performance contained in these materials is illustrative and no assurance is given that any indicative returns, performance or results, whether historical or hypothetical, will be achieved . J . P . Morgan undertakes no duty to update this information . In the event of any inconsistency between the information presented herein and any offering documents, the offering documents shall govern . Backtesting : Hypothetical backtested performance measures have inherent limitations and are designed with the benefit of hindsight . Alternative modelling techniques might produce significantly different results and may prove to be more appropriate . For time periods prior to the launch of each of the Basket Constituents, and prior to that Basket Constituent’s satisfaction of a minimum liquidity standard, backtesting uses alternative performance derived from the reference index tracked by that Basket Constituent as of the Index’s live date (or the reference index originally tracked by that Basket Constituent, if the reference index as of the Index’s live date was not available for the relevant period), after deducting hypothetical fund expenses equal to such Basket Constituent’s expense ratio as of the Index’s live date, rather than actual performance of that Basket Constituent for that period . The use of alternative “proxy” performance information in the calculation of hypothetical backtested weights and levels may have resulted in different, perhaps significantly different, weights and higher levels than would have resulted from the use of actual performance information of the Constituents . Past performance, and especially hypothetical backtested performance, is not indicative of future results . This type of information has inherent limitations and you should carefully consider these limitations before placing reliance on such information . The 10 Year Volatility (Annualized) on the previous page is a measure of market risk, calculated as of the square root of two hundred and fifty - two ( 252 ) multiplied by the sample standard deviation of the daily logarithmic returns of each applicable index (considering only days for which levels are available for all three) over the preceding 10 years . The Sharpe Ratio on the previous page is a measure of risk - adjusted performance, calculated as the annualized 10 year excess return (calculated as the annualized compounded monthly returns of the applicable index over the monthly returns of the J . P . Morgan Cash Index USD 3 Month, which tracks the return of a notional 3 - month U . S . dollar time deposit) divided by the 10 Year Volatility (Annualized) . Investment suitability must be determined individually for each investor, and CDs linked to the Index may not be suitable for all investors . This material is not a product of J . P .
