MARCH 2026 | MerQube US Tech+ Vol Advantage Index Selected Risks þÿ Our affiliate, J.P. Morgan Securities LLC (“JPMS”), coordinated with the MerQube (the “Index Sponsor”) in the development of the Index. þÿ The level of the Index will include a 6.0% per annum daily deduction. þÿ The level of the Index will include the deduction of a notional financing cost. þÿ The Index Sponsor may adjust the Index in a way that affects its level, and the Index Sponsor has no obligation to consider y our interests. þÿ The Index may not approximate its target volatility. þÿ The Index is subject to risks associated with the use of significant leverage. þÿ The Index may be significantly uninvested. þÿ The Index, which was established on June 22, 2021, has a limited operating history and may perform in unanticipated ways. þÿ An investment linked to the Index will be subject to risks associated with non - U.S. securities. þÿ The Index may not be successful or outperform any alternative strategy that may be employed in respect of the underlying asse t t o which the Index is linked (the “Underlying Asset”). þÿ The Index is subject to risks relating to the Invesco QQQ Trust SM , Series 1 (the “QQQ Fund”). The QQQ Fund is subject to management risk, and the performance and market value of the QQQ Fund , particularly during periods of market volatility, may not correlate with the performance of the QQQ Fund’s underlying index a s w ell as the net asset value per share. The risks identified above are not exhaustive. You should also review carefully the related “Risk Factors” section in the pro spe ctus supplement and the relevant product supplement and underlying supplement and “Selected Risk Considerations” in the relevant pricing supplement. Disclaimer Important Information 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. All information herein is s ubj ect to change without notice, however, J.P. Morgan undertakes no duty to update this information. In the event of any inconsistency between the information presented herein and any offering document , t he offering document shall govern. Use of hypothetical backtested returns Any backtested historical performance and weighting information included herein is hypothetical. The constituent may not have tr aded in the manner shown in the hypothetical backtest of the Index included herein, and no representation is being made that the Index will achieve similar performance. The hypothetical histor ica l levels presented herein have not been verified by an independent third party, and such hypothetical historical levels have inherent limitations. There are frequently significant differences betwee n h ypothetical backtested performance and actual subsequent performance. The results obtained from backtesting information should not be considered indicative of the actual results that might be obt ain ed from an investment in notes referencing the Index. J.P. Morgan provides no assurance or guarantee that notes linked to the Index will operate or would have operated in the past in a manner consiste nt with these materials. The hypothetical historical levels presented herein have not been verified by an independent third party, and such hypothetical historical levels have inherent limitations. Alte rna tive simulations, techniques, modeling or assumptions might produce significantly different results and prove to be more appropriate. Actual results will vary, perhaps materially, from the hypo the tical backtested returns and allocations presented in this document. HISTORICAL AND BACKTESTED PERFORMANCE AND ALLOCATIONS ARE NOT INDICATIVE OF FUTURE RESULTS. Hypothetical back - tested performance measures have inherent limitations. Hypothetical back - tested performance is derived by mean s of the retroactive application of a back - tested model that has been designed with the benefit of hindsight. Hypothetical back - tested results are neither an indicator nor a guarantee of future retu rns. Alternative modelling techniques might produce significantly different results and may prove to be more appropriate. A copy of the index methodology is available upon request or can be viewed on M erQ ube’s website. MerQube performed the calculation of the hypothetical back - tested performance data. Neither J.P. Morgan Securities LLC (JPMS), n or any of its affiliates paid MerQube to perform these calculations. JPMS has entered into a license agreement with MerQube, Inc. that provides for an exclusive license to it and certain of its affiliate d o r subsidiary companies, in exchange for a fee, of the right to use the Indices, which are owned and published by MerQube, Inc. JPMS worked with MerQube in developing the guidelines and policies governing t he composition and calculation of the Index. The policies and judgments for which JPMS was responsible could have an impact, positive or negative, on the level of the Index and the value of your no tes . JPMS is under no obligation to consider your interests as an investor in the notes in its role in developing the guidelines and policies governing the Index or making judgments that may affect the l eve l of the Index. In addition, the QQQ Fund replaced the E - Mini Nasdaq - 100 futures (the “Futures Contracts”) as the Underlying Asset on February 9 , 2024. No assurance can be provided that the QQQ Fund is an appropriate substitute for the Futures Contracts. This replacement may adversely affect the performance of the Index and the va lue of the notes, as the QQQ Fund, subject to a notional financing cost, may perform worse, perhaps significantly worse, than the Futures Contracts. The Index lacks any operating history with the Q QQ Fund as the Underlying Asset prior to February 9, 2024 and may perform in unanticipated ways. Investors in the notes should bear this difference in mind when evaluating the hypothetical back - tested performance shown in this document.
