Backtesting: Hypothetical backtested performance measures have inherent limitations. Alternative modelling techniques might produce signif ica ntly different results and may prove to be more appropriate. Past performance, and especially hypothetical back - tested performance, is not indicative of future results. This ty pe of information has inherent limitations and you should carefully consider these limitations before placing reliance on such information. 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 bet ween hypothetical backtested performance and actual subsequent performance. The results obtained from backtesting information should not be considered indicative of the actual results that mi ght be obtained 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 consistent with these materials. The hypothetical historical levels presented herein have not been verified by an independent third party, and such hypothetical historical levels have in her ent limitations. Alternative simulations, techniques, modeling or assumptions might produce significantly different results and prove to be more appropriate. Actual results will vary, perhaps ma terially, from the hypothetical 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 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 Futures Contracts as the Underlying Asset on the Amendment Effective Date. No assuranc e c an 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 value 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 QQQ Fund as the Under lyi ng Asset prior to the Amendment Effective Date and may perform in unanticipated ways. Investors in the notes should bear this difference in mind when evaluating the hypothetical back - tested perf ormance shown in this document. 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 available for all three) over the preceding 10 years.
