Executive summary The J.P. Morgan Total Return SM Index (the “Index”) was launched as J.P. Morgan Investable Indices’ flagship “smart beta” fixed income index with more than six years of live track record The Index applies a rules - based methodology to evaluate recent market conditions and allocate dynamically across up to twelve ETFs that each track a U.S. dollar fixed income sector By looking at recent ETF returns and volatility, the Index indirectly uses cross - sectoral momentum to vary its duration, credit and liquidity risk profiles based on market conditions The Index can allocate opportunistically to ETFs that provide exposure to alternative fixed income assets (e.g., TIPS, high y iel d, emerging markets, floating - rate notes) Over its live period, the Index has outperformed the Bloomberg US Aggregate Bond Index by 1.28% p.a. 1 with outperformance in both rising and declining rate environments J.P. Morgan can provide exposure to the Index in delta - one notes Live track record delivering 1.28% p.a. outperformance over the Bloomberg US Aggregate Bond Index Systematic portfolio construction Notes linked to the Index are subject to the credit risk of JPMorgan Chase Financial Company LLC, as issuer of the notes, and JPMorgan Chase & Co., as guarantor of the notes Notes linked to the Index are not listed on any exchange Greater perceived market acceptance of ETFs STRENGTHS CONSIDERATIONS 1 1 Note: Past performance is no guarantee of future performance.

Performance above based on the historical live close levels of eac h index from July 13, 2017 through December 29, 2023. The “Yield” of the J.P. Morgan Total Return SM Index shown above is calculated as a weighted average of the yield - to - worst of each underlying index of each ETF to which the I ndex was allocated as of the last day of the immediately preceding calendar month. An ETF’s underlying index’s yield - to - worst is the weighted average of the yield - to - worst of each of the bond components of that underlying index and is calculated and published by Bloomberg Professional® service (“Bloomberg”), other than the yield - to - worst of the und erlying index of J.P. Morgan EMBI Global Core which is calculated and published by J.P. Morgan. A bond’s yield - to - worst is the lesser of that bond’s yield - to - call (if that bond is callable) and yiel d - to - maturity. A bond’s yield - to - maturity and yield - to - call are the estimated total returns, expressed as per annum rates, anticipated to be paid on that bond if it is held until maturity, or until called (as app licable), assuming all payments are made as scheduled. If an ETF’s underlying index’s yield - to - worst is not available, J.P. Morgan will calculate the Yield using that ETF’s yield - to - w orst, as provided by Bloomberg under the “YAS Bond Yield” field, or, if the ETF’s yield - to - worst is not available, using that ETF’s dividend indicated yield, as provided by Bloomberg. The dividend indicat ed yield of an ETF is calculated as the most recently announced dividend amount for that ETF, annualized based on the dividend frequency, then divided by that ETF’s current market price. If an ETF p ays an interim and/or final dividend, then the dividend indicated yield of that ETF is calculated by adding the dividend amount from the most recently announced interim dividend and the most recently ann ounced final dividend, and dividing that sum by that ETF’s current market price. Abnormal dividends are not included in the Yield calculation. For purposes of the Yield calculation, J.P. Morga n h as used the yield - to - worst of each ETF’s underlying index other than iShares® Preferred and Income Securities ETF (PFF) for which the dividend indicated yield was used. The Yield of the Bloomberg US Aggregate Bond Index is calculated and published by Bloomberg to the ticker “LBUSYW Index”. Past Yields of the Index are not indicative of future results. All payments on the bonds composing an ETF’s underlying index are subject to the credit risk of the issuers of those bonds. 1 Calculated as the arithmetic average of the Index’s daily Yield, calculated as described above, from November 30, 2023 throug h D ecember 29, 2023. 2 Calculated as the arithmetic average of the Index’s daily Yield, calculated as described above, from December 30, 2022 throug h D ecember 29, 2023.

Selected risks associated with the Index Our affiliate, J.P. Morgan Securities LLC (“JPMS”), is the sponsor and index calculation agent of the Index and may adjust th e I ndex in a way that affects its level — Policies and judgments for which JPMS is responsible could have an impact, positive or negative, on the level of the Index an d the value of your investment. JPMS may have interests adverse to your interests as an investor in notes linked to the Index, and JPMS is und er no obligation to consider your interests. The securities of JPMorgan Chase & Co. are currently held by several Constituents — JPMC will not, however, have any obligation to consider your interests in taking any corporate action that might affect the level of these Constituents, their reference indices or the In dex . There are risks associated with the Index’s momentum allocation strategy — If market conditions do not represent a continuation of prior observed trends, the level of the Index, which is rebalanced monthly based on prior trends, may decline. Additionally, even when the values o f t he Constituents are trending downwards, the Index will continue to be composed of the downward trending Constituents between monthly rebalancing dates. The Index may not approximate its target volatility. The Index may perform poorly during periods characterized by short - term volatility — The Index’s strategy is based on momentum investing. Momentum investing strategies are effective at identifying the current market direction in trending markets. Consequently, the Index may perform poorly in non - trending, “choppy” markets characterized by short - term volatility. An ETF may not fully replicate its reference index and may hold securities different from those included in its reference ind ex. The performance of an ETF may also not correlate with the performance of its reference index — The performance of each ETF may not correlate with its net asset value per share, which could materially and adversely affect the value of the notes in the secondary market and/or reduce any payment on the n ote s. At a time when the value of one Constituent increases, the values of the other Constituents may not increase as much or may e ven decline — The Index may not perform as well as an alternative index that tracks only one Constituent. The Constituents are subject to monthly rebalancing and weighting constraints by asset type and on subsets of assets based on hi storical volatility — No assurance can be given that the investment strategy used to construct the Index will outperform any alternative investment in the Constituents. 4

Selected risks associated with the Index The Constituent of the Index may be replaced by a substitute constituent ETF 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 significantl y b etter or worse than the original Constituent. Other key risks: 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 is subject to significant risks associated with fixed - income securities, including interest rate - related risks and cre dit risk. The Index is subject to significant risks associated with high - yield fixed income securities, including credit risk. The Index is subject to significant risks associated with floating rate notes. The Index is subject to significant risks associated with mortgage - backed securities. The Index is subject to significant risks associated with preferred stock. The Index is subject to significant risks associated with hybrid securities. The Index is subject to risks associated with non - U.S. securities markets, including emerging markets. The Index may not be successful or outperform any alternative strategy that might be employed in respect of the Constituents. The risks identified above are not exhaustive. You should also carefully review the related “Risk Factors” section in the re lev ant product supplement and underlying supplement and the “Selected Risk Considerations” in the relevant pricing supplement. 5
