Morgan Total Return SM Index (the “Index”) attempts to provide a dynamic and diversified allocation to 12 U.S. dollar fixed income ETFs (the “Basket Constituents”), each providing exposure to a different sector of the U.S. dollar fixed income market. The Index rebalances monthly into the portfolio with the highest performance over the previous 6 months, generally subject to a 5% historical volatility threshold, and constituent and sector concentration limits. The Index is calculated on a total return basis. The Index was established on July 13, 2017. Levels are published on Bloomberg and to JPMorganIndices.com, using the ticker JPUSTRI.

FEBRUARY 2026 | J.P. Morgan Total Return SM Index Selected Risks þÿ Our affiliate, J.P. Morgan Securities LLC (“JPMS”), is the Index Sponsor and may adjust the Index in a way that affects its l eve l. 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 c ons ider your interest as an investor with returns linked to the Index. þÿ The Index was established on July 13, 2017, and has a limited operating history. þÿ There are risks associated with a momentum - based investment strategy. If market conditions do not represent a continuation of pr ior observed trends, Index performance may be adversely impacted. þÿ The Index comprises notional assets and liabilities. There is no actual portfolio of assets to which any person is entitled o r i n which any person has any ownership interest. þÿ The Index may not be successful, may not outperform any alternative strategy and may not maintain volatility below its histor ica l volatility threshold of 5%. þÿ The investment strategy used to construct the Index involves monthly rebalancing and weighting constraints that are applied t o t he Basket Constituents, which may adversely impact performance. þÿ Changes in the values of the Basket Constituents may offset each other. þÿ There are risks associated with correlation between the Basket Constituents. If the performances of the Basket Constituents b eco me highly correlated during periods of negative performance, Index performance may be adversely impacted. þÿ Each Basket Constituent composing the Index may be replaced by a substitute constituent upon the occurrence of certain extrao rdi nary events. þÿ The Index should not be compared to any other index or strategy sponsored by any of our affiliates and cannot necessarily be con sidered a revised, enhanced or modified version of any other J.P. Morgan index. þÿ The securities of our parent company, JPMorgan Chase & Co., are held by several of the Basket Constituents. þÿ The performance of an ETF, particularly during periods of market volatility, may not correlate with the performance of its re fer ence index. þÿ The Index is subject to significant risks associated with fixed - income securities (including interest rate - related risks and cre dit 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 infl ation - protected securities and non - U.S. securities markets, including emerging markets. þÿ 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 rel eva nt 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 d uty 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. Altern at ive 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 Constituen ts, 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 Constitu ent 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), af ter 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 highe r l evels 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 f utu re 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 hu ndred 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 ) o ver 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 ret urn (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 o f a notional 3 - month U.S. dollar time deposit) divided by the 10 Year Volatility (Annualized).
