Index supplement to the prospectus dated April 13, 2023, the prospectus supplement dated April 13, 2023, the prospectus adden dum dated June 3, 2024, the product supplement no. 3 - I dated April 13, 2023 and the underlying supplement no. 24 - I dated September 1 , 2023 Registration Statement Nos. 333 - 270004 and 333 - 270004 - 01 Dated February 9, 2026 Rule 424(b)(3) PERFORMANCE UPDATE The J.P. Morgan Dynamic Blend Index (the “Index”) attempts to provide a dynamic and rules - based allocation to an Equity Constituent and a Bond Constituent (together, the “Portfolio Constituents”) while targeting a level volatility of 3.0%. The “Equity Constituent” is the J.P. Morgan US Large Cap Equities Futures Index (ticker: [JPUSLGEQ]), which seeks to provide exposure to large - cap U.S. stocks by rolling its exposure to S&P 500 Index futures. The “Bond Constituent” is the J.P. Morgan 2Y US Treasury Futures Index (ticker: [JPUS2YT]), and attempts to short - term U.S. treasury bonds by rolling its exposure to 2 - year US treasury note futures. The Index is subject to a daily deduction of a 0.95% per annum. The Index was established on March 23, 2021. Levels are published on Bloomberg and to JPMorganIndices.com, using the ticker JPUSDYBL. Hypothetical and actual historical performance: Jan 2016 through Jan 2026 Please see the footnotes at the bottom of this page and “Backtesting” on the following page for information on backtested performance and proxies. Historical performance measures for the Index represent hypothetical backtested performance using the hypothetical and actual pe rformance of each Portfolio Constituent through March 22, 2021 (labeled “Backtested” in the chart above); and actual performance from March 23, 2021 through January 31, 2026 (labeled “Actual” in th e c hart above). The “Domestic 20/80 Portfolio (ER)” is a notional portfolio providing a monthly - rebalancing 20%/80% weighted exposure to the S&P 500 Total Return Index and the Bloomberg Barclays U.S. Aggr egate Bond Total Return Index. The “Global 20/80 Portfolio (ER)” is a notional portfolio providing a monthly - rebalancing 20%/80% weighted exposure to the MSCI ACWI Net Total Return Index and the Blo omberg Barclays Global Aggregate Total Return Index Value Unhedged USD (a global investment - grade bond index). Each notional portfolio is calculated on an excess return basis, i.e., net of a notional fi nancing cost deduction equal to the return of the J.P. Morgan Cash Index USD 3 Month, which tracks the return of a notional 3 - month U.S. dollar time deposit. Weights within these notional portfolios are intended to approximate the average weights within the Index, but will not correspond to historical or future weights within the Index. The notional portfolios track assets that differ from those tracked by the Index and are not rebalanced on the same schedule as the Index. All performance data for the Domestic 20/80 Portfolio (ER) and the Global 20/80 Portfolio (ER) is hypothetical and there is no guarantee that the Index will outper for m either one, or any other benchmark or index, in the future. PAST PERFORMANCE AND BACKTESTED PERFORMANCE ARE NOT INDICATIVE OF FUTURE RESULTS. Please see the Disclaimer on the following page.

FEBRUARY 2026 | J.P. Morgan Dynamic Blend Index Selected Risks þÿ Our affiliate, J.P. Morgan Securities LLC (“JPMS”), is the Index Sponsor for the Index and each Portfolio Constituent, and ma y a djust the Index or each Portfolio Constituent in a way that affects their level. The policies and judgments for which JPMS is responsible could have an impact, positive or negative, on the leve l o f the Index or each of the Portfolio Constituents and the value of your investment. JPMS is under no obligation to consider your interest as an investor with returns linked to the Index. þÿ The level of the Index is calculated on an excess return basis and reflects the daily deduction of a fee of 0.95% per annum. þÿ Our parent company, JPMorgan Chase & Co. (“JPMC”), is currently one of the companies that make up the S&P 500® Index, the ref ere nce index underlying the underlying futures contracts of the Equity Constituent. þÿ The Index was established on March 23, 2021 and the Portfolio Constituents were established on December 22, 2020 and each has a limited operating history. 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 approximate its target volatility of 3. 0%. þÿ The performance of the Index may be adversely affected by its target volatility of 3.0%. þÿ The investment strategy used to construct the Index involves daily adjustments to its notional exposures to its Portfolio Con sti tuents, which may adversely impact performance. þÿ The exposure of the Index to the Bond Constituent may be greater, perhaps significantly greater, than its exposure to the Equ ity Constituent. þÿ The Index will be partially uninvested when every unlevered long - only portfolio of the Portfolio Constituents whose weights sum to 100% have volatility above the target volatility. Any uninvested portion will earn no return. þÿ The Index may be more heavily influenced by the performance of the Equity Constituent than the performance of the Bond Consti tue nt in general over time. þÿ Changes in the values of the Portfolio Constituents may offset each other. þÿ There are risks associated with correlation between the Portfolio Constituents. If the performances of the Portfolio Constitu ent s become highly correlated during periods of negative performance, Index performance may be adversely impacted. þÿ Each Portfolio Constituent composing the Index may be replaced by a substitute Index or futures contract upon the occurrence of certain extraordinary events. þÿ Each Portfolio Constituent is subject to significant risks associated with the underlying futures contracts. þÿ Suspension or disruptions of market trading in the underlying futures contracts may adversely affect the value of investments li nked to the Index. þÿ An increase in the margin requirements for the underlying futures contracts included in the Portfolio Constituents may advers ely affect the level of that Portfolio Constituent. þÿ The Index may in the future include underlying futures contracts that are not traded on regulated futures exchanges. þÿ Negative roll returns associated with the underlying futures contracts constituting the Portfolio Constituents may adversely aff ect the performance of the Portfolio Constituents and the value of investments linked to the Index. 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 Index is subject to significant risks associated with fixed - income securities (including interest rate - related risks and cre dit risk. þÿ Investments linked to the Index may be subject to the credit risk of JPMorgan Financial and JPMorgan Chase & Co.

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 undert ake s 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. Altern at ive modelling techniques might produce significantly different results and may prove to be more appropriate. For time periods prior to the existence of any equity c ons tituent included in the Index, the hypothetical backtesting uses alternative performance information derived from futures contract series with the same reference index. The use of alter nat ive “proxy” performance information in the calculation of hypothetical backtested weights and levels may have resulted in different, perhaps significantly different, weights and hi ghe r levels than would have resulted from the use of actual performance information of the Portfolio 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 hu ndred and fifty - two (252) multiplied by the sample standard deviation of the daily logarithmic returns of each applicable index or portfolio (considering only days for which levels are ava ilable 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 10 Year Return (Annualized) d ivided by the 10 Year Volatility (Annualized).
