SEPTEMBER 2025 | J.P. Morgan Kronos+ SM Index Selected Risks Our affiliate, J.P. Morgan Securities LLC (“JPMS”), is the sponsor and calculation agent of the Index and may adjust the Index in a way that atfects its level. The level of the Index will include the deduction of a fee of 0.95% per annum and, in some circumstances, a notional financing cost based on the Etfective Federal Funds Rate. JPMorgan Chase & Co. is currently one of the companies that make up the Constituent. There are risks associated with the Index’s turn - of - month strategy. There are risks associated with the Index’s option expiry momentum strategy. There are risks associated with the Index’s mean reversion strategy. The Index’s strategies are applied during only a portion of each month. The Index may be adversely atfected by an overlap between its turn - of - the - month strategy and its month - end mean reversion strategy. The Index may be uninvested in the Constituent. The Constituent of the Index may be replaced by a substitute index in certain extraordinary events. The notional cash return will be negatively atfected if the underlying interest rate is negative. The Index, which was established on December 22, 2020, 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 or in which any person has any ownership interest. The Index may not be successful or outperform any alternative strategy that may be employed of the Constituents. The Etfective Federal Funds Rate is atfected by a number of factors and may be volatile. The method pursuant to which the Etfective Federal Funds Rate is determined may change, and any such change may adversely atfect the value of notes linked to the Index. The risks identified above are not exhaustive. You should also review carefully the related “Risk Factors” section in the prospectus supplement and the relevant product supplement and underlying supplement and the “Selected Risk Considerations” in the relevant pricing supplement.
