conditions and other relevant factors and assumptions existing at that time. See “Risk Factors — The estimated value of the PLUS does not represent future values of the PLUS and may differ from others’ estimates” in this document.

The estimated value of the PLUS will be lower than the original issue price of the PLUS because costs associated with selling, structuring and hedging the PLUS are included in the original issue price of the PLUS. These costs include the selling commissions paid to JPMS and other affiliated or unaffiliated dealers, the structuring fee, the projected profits, if any, that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the PLUS and the estimated cost of hedging our obligations under the PLUS. Because hedging our obligations entails risk and may be influenced by market forces beyond our control, this hedging may result in a profit that is more or less than expected, or it may result in a loss. We or one or more of our affiliates will retain any profits realized in hedging our obligations under the PLUS. See “Risk Factors — The estimated value of the PLUS will be lower than the original issue price (price to public) of the PLUS” in this document.

You should review carefully the section entitled “Material U.S. Federal Income Tax Consequences” in the accompanying product supplement no. MS-1-I. The following discussion, when read in combination with that section, constitutes the full opinion of our special tax counsel, Davis Polk & Wardwell LLP, regarding the material U.S. federal income tax consequences of owning and disposing of the PLUS.

Based on current market conditions, in the opinion of our special tax counsel, your PLUS should be treated as “open transactions” that are not debt instruments for U.S. federal income tax purposes, as more fully described in “Material U.S. Federal Income Tax Consequences — Tax Consequences to U.S. Holders — Notes Treated as Open Transactions That Are Not Debt Instruments” in the accompanying product supplement. Assuming this treatment is respected, the gain or loss on your PLUS should be treated as long-term capital gain or loss if you hold your PLUS for more than a year, whether or not you are an initial purchaser of PLUS at the issue price. However, the IRS or a court may not respect this treatment of the PLUS, in which case the timing and character of any income or loss on the PLUS could be materially and adversely affected. In addition, in 2007 Treasury and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. The notice focuses in particular on whether to require investors in these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments; the relevance of factors such as the nature of the underlying property to which the instruments are linked; the degree, if any, to which income (including any mandated accruals) realized by non-U.S. investors should be subject to withholding tax; and whether these instruments are or should be subject to the “constructive ownership” regime, which very generally can operate to recharacterize certain long-term capital gain as ordinary income and impose a notional interest charge. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the PLUS, possibly with retroactive effect. You should consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the PLUS, including possible alternative treatments and the issues presented by this notice.

Section 871(m) of the Code and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% withholding tax (unless an income tax treaty applies) on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities. Section 871(m) provides certain exceptions to this withholding regime, including for instruments linked to certain broad-based indices that meet requirements set forth in the applicable Treasury regulations (such an index, a “Qualified Index”). Additionally, a recent IRS notice excludes from the scope of Section 871(m) instruments issued prior to January 1, 2021 that do not have a delta of one with respect to underlying securities that could pay U.S.-source dividends for U.S. federal income tax purposes (each an “Underlying Security”). Based on certain determinations made by us, we expect that Section 871(m) will not apply to the PLUS

with regard to Non-U.S. Holders. Our determination is not binding on the IRS, and the IRS may disagree with this determination. Section 871(m) is complex and its application may depend on your particular circumstances, including whether you enter into other transactions with respect to an Underlying Security. If necessary, further information regarding the potential application of Section 871(m) will be provided in the pricing supplement for the PLUS. You should consult your tax adviser regarding the potential application of Section 871(m) to the PLUS.

Withholding under legislation commonly referred to as “FATCA” may (if the PLUS are recharacterized as debt instruments) apply to amounts treated as interest paid with respect to the PLUS, as well as to payments of gross proceeds of a taxable disposition, including redemption at maturity, of a PLUS. However, under a 2015 IRS notice, this regime will not apply to payments of gross proceeds (other than any amount treated as interest) with respect to dispositions occurring before January 1, 2019. You should consult your tax adviser regarding the potential application of FATCA to the PLUS.

The PLUS are offered to meet investor demand for products that reflect the risk-return profile and market exposure provided by the PLUS. See “How the PLUS Work” in this document for an illustration of the risk-return profile of the PLUS and “S&P 500^® Index Overview” in this document for a description of the market exposure provided by the PLUS.

The original issue price of the PLUS is equal to the estimated value of the PLUS plus the selling commissions paid to JPMS and other affiliated or unaffiliated dealers and the structuring fee, plus (minus) the projected profits (losses) that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the PLUS, plus the estimated cost of hedging our obligations under the PLUS.

Subject to regulatory constraints, JPMS intends to use its reasonable efforts to offer to purchase the PLUS in the secondary market, but is not required to do so. JPMS, acting as agent for JPMorgan Financial, will pay all of the selling commissions it receives from us to Morgan Stanley Wealth Management. In addition, Morgan Stanley Wealth Management will receive a structuring fee as set forth on the cover of this document for each PLUS.

We or our affiliate may enter into swap agreements or related hedge transactions with one of our other affiliates or unaffiliated counterparties in connection with the sale of the PLUS and JPMS and/or an affiliate may earn additional income as a result of payments pursuant to the swap or related hedge transactions. See “— Supplemental use of proceeds and hedging” above and “Use of Proceeds and Hedging” in the accompanying product supplement.

We expect that delivery of the PLUS will be made against payment for the PLUS on or about the original issue date set forth on the front cover of this document, which will be the third business day following the pricing date of the PLUS (this settlement cycle being referred to as “T+3”). Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two business days, unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade PLUS on any date prior to two business days before delivery will be required to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisors.

You may revoke your offer to purchase the PLUS at any time prior to the time at which we accept such offer by notifying the applicable agent. We reserve the right to change the terms of, or reject any offer to purchase, the PLUS prior to their issuance. In the event of any changes to the terms of the PLUS, we will notify you and you will be asked to accept such changes in connection with your purchase. You may also choose to reject such changes in which case we may reject your offer to purchase.

You should read this document together with the accompanying prospectus, as supplemented by the accompanying prospectus supplement relating to our Series A medium-term notes of which these PLUS are a part, and the more detailed information contained in the accompanying product supplement and the accompanying underlying supplement.

This document, together with the documents listed below, contains the terms of the PLUS and supersedes all other prior or contemporaneous oral statements as well as any other written materials including preliminary or indicative pricing terms, correspondence, trade ideas, structures for implementation, sample structures, stand-alone fact sheets, brochures or other educational materials of ours. You should carefully consider, among other things, the matters set forth in the “Risk Factors” sections of the accompanying product supplement and the accompanying underlying supplement, as the PLUS involve risks not associated with

conventional debt securities. We urge you to consult your investment, legal, tax, accounting and other advisers before you invest in the PLUS.
