The turn - of - month effect  Historically, the S&P 500’s performance has been better the first few and last few days of the month than for the rest. Some hav e attributed this to:  month - end portfolio adjustments by institutions  distributions from pensions and other retirement accounts that are immediately reinvested  monthly investments by retail mutual fund investors through Systematic Investment Plans  However, other factors may be responsible for this effect — there can be no assurance that any factor will persist or cause this effect in the future.

May 2001 – Jun 2021. “Average daily returns for months in which the SPTR Index was positive” are compound a verage daily returns of the S&P ® Total Return Index on the specified days in months in which the S&P 500 ® Total Return Index return during the period from the trading day following the prior options expiry to the 4 th trading day prior to the options expiry (the “relevant period”) is positive; “Average daily returns for months in which the SPTR Index was negative” are compound average daily returns of th e S &P ® Total Return Index on the specified days in months in which the S&P 500 ® Total Return Index during the relevant period is negative. 1 Specifically, the least - squares regression from July 1983 to December 2020 of the trailing 4 - trading day return as of the Monda y following the third (3rd) Friday of the month (or if such Monday is a holiday, the prior trading day) against the return from the Monday following the third (3rd) Friday of the prior month to the trading day that is 5 trading days before the Monday following the third (3rd) Friday , has a slope of 11% and an intercept of 0%.

Mean reversion into month - end  Historically, the S&P 500’s return has exhibited mean reversion in the last week of the month: this week’s return is on average approximately - 12% of the return in the prior weeks 2  Some theories speculate this might be due to month - end rebalancing flows from institutional investors targeting fixed portfolio weights  However, other factors may be responsible for this effect — there can be no assurance that any factor will persist or cause this effect in the future.

Morgan Kronos US Equity (JPUSKRSP) Index Month - end  Six trading days before the last trading day of the month, if the prior day’s S&P 500 level is:  Above its closing price on the prior month - end, then the Index allocates 50% long exposure to the S&P 500 until 2 days prior to month - end, then provides 100% (unleveraged) exposure to the S&P 500 (due to overlap with the turn - of - month)  Below its closing price on the prior month - end, the Index provides a 150% leveraged long exposure to the S&P 500  At month - end, the Index rebalances into (or maintains) its 150% leveraged start - of - month allocation Turn - of - month  For the first 4 trading days of each month, the Index provides a 150% leveraged long exposure to the S&P 500 Options expiry  Three trading days before the 3 rd Friday of the month (the customary monthly S&P 500 index options expiry), if the prior day’s S&P 500 level is:  Above its last closing price after the prior expiry, then the Index provides a 150% leveraged long exposure to the S&P 500 until the first trading day after the 3 rd Friday of the month  Below its last closing price after the prior expiry, then the Index allocates to 50% long exposure to the S&P 500  The Index reverts this allocation on the first trading day following such 3 rd Friday Rest of the month  Otherwise, the Index provides 100% (unleveraged) exposure to the S&P 500 7

Selected risks associated with the Index Our affiliate, J.P. Morgan Securities plc (“JPMS plc”), is the sponsor and calculation agent of the Index and may adjust the Ind ex in a way that affects its level — Policies and judgments for which JPMS plc is responsible could have an impact, positive or negative, on the level of the Inde x and the value of your investment. JPMS plc may have interests adverse to your interests as an investor in notes linked to the Index, and JPMS plc i s u nder no obligation to consider your interests. The level of the Index will include the deduction of a fee of 0.35% per annum and, in some circumstances, a notional financin g c ost based on the Effective Federal Funds Rate — This index fee and, when the exposure to the S&P 500 Index (the “Constituent”) is leveraged, the notional financing cost will b e deducted daily. As a result of the deduction of this index fee and, when applicable, the notional financing cost, the level of the Index will trail the value of a hypothetical identically constituted synthetic portfolio from which no such fee or cost is deducted, assuming that the rates und erlying the notional financing cost remain positive. JPMorgan Chase & Co. is currently one of the companies that make up the Constituent — JPMC will not, however, have any obligation to consider your interests in taking any corporate action that might affect the level of the Constituent. There are risks associated with the Index’s turn - of - month strategy — No assurance can be given that the turn - of - the - month strategy will be successful or that it will outperform any alternative strategy. There are risks associated with the Index’s option expiry momentum strategy — No assurance can be given that the options expiry momentum strategy will be successful or that it will outperform any alternative strategy. There are risks associated with the Index’s mean reversion strategy — No assurance can be given that the month - end mean reversion strategy will be successful or that it will outperform any alternative strategy. The Index’s strategies are applied during only a portion of each month — Each of the Index’s strategies is implemented over only a limited number of days in a calendar month as described above. Outside of these limited number of days, the Index will track 100% of the performanc e o f the Constituent (subject to the deduction of the index fee) and will not benefit from the application of any strategy. The Index may underperform the Co nst ituent due to the limited application of the strategies along with the deduction of the index fee and, when applicable, the notional financing cost. 14

Selected risks associated with the Index The Index may be adversely affected by an overlap between its turn - of - the - month strategy and its month - end mean reversion strate gy — During the final two Index Business Days of each month, the turn - of - the - month strategy and the month - end mean revision strategy are both ap plicable, subject to a maximum exposure to the Constituent of 150%. As a result, the exposure to the Constituent may be higher or lower than would hav e been the case had only one of those strategies been applied and the performance of the Index may be worse than if only one strategy were applied or no maximum exposure limit were applied. The Index may be significantly uninvested — The level of the Constituent may increase significantly while the exposure of the Index to the Constituent is 50%, but the Index will benefit from only 50% of any such increase. The index fee is deducted daily at a rate of 0.35% per annum, eve n when the Index provides only 50% exposure to the Constituent. The Constituent of the Index may be replaced by a substitute index in certain extraordinary events — Changing a Constituent may affect the performance of the Index, and therefore, the return on an investment, as the replacement Constituent may perform significantly better or wor se than the original Constituent. The notional cash return will be negatively affected if the underlying interest rate is negative — If the Effective Federal Funds Rate becomes negative, when the exposure to the Constituent is 0%, the notional cash return will have a negative effect on the performance of the In dex and therefore the value of the notes. Other key risks:  The Index, which was established on June 11, 2021, has a limited operating history and may perform in unanticipated ways.  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.  The Index may not be successful or outperform any alternative strategy that might be employed in respect of the Constituents.  The Effective Federal Funds Rate is affected by a number of factors and may be volatile.  The method pursuant to which the Effective Federal Funds Rate is determined may change, and any such change may adversely aff ect the value of notes linked to the Index. The risks identified above are not exhaustive. You should also carefully review the related “Risk Factors” section in the rel eva nt product supplement and underlying supplement and the “Selected Risk Considerations” in the relevant pricing supplement. 15
