Enhanced Trigger Jump Securities Based on the Value of the Class A Common Stock of Snowflake Inc. due June 25, 2025

Fully and Unconditionally Guaranteed by Morgan Stanley

Principal at Risk Securities

The Enhanced Trigger Jump Securities, which we refer to as the securities, are unsecured obligations of Morgan Stanley Finance LLC (“MSFL”) and are fully and unconditionally guaranteed by Morgan Stanley. The securities will pay no interest and do not guarantee the return of any of the principal amount at maturity. At maturity, you will receive for each security that you hold an amount in cash that will vary depending on the arithmetic average of the closing prices of the class A common stock of Snowflake Inc. on each of the five averaging dates (the “final share price”). If the final share price, as measured on the five averaging dates, is greater than or equal to 70% of the initial share price, which we refer to as the downside threshold level, you will receive for each security that you hold at maturity the upside payment of $219.00‬ per security in addition to the stated principal amount. However, if the final share price is less than the downside threshold level, meaning that the underlying stock has depreciated by more than 30% from its initial share price, the payment due at maturity will be significantly less than the stated principal amount of the securities by an amount that is proportionate to the full percentage decrease in the final share price from the initial share price. Under these circumstances, the payment at maturity per security will be less than $700 and could be zero. Accordingly, you may lose your entire initial investment in the securities. The securities are for investors who seek an equity-based return and who are willing to risk their principal and forgo current income and returns above the upside payment in exchange for the upside payment feature that applies to a limited range of performance of the underlying stock. The securities are notes issued as part of MSFL’s Series A Global Medium-Term Notes Program.

All payments are subject to our credit risk. If we default on our obligations, you could lose some or all of your investment. These securities are not secured obligations and you will not have any security interest in, or otherwise have any access to, any underlying reference asset or assets.

Morgan Stanley Finance LLC

Enhanced Trigger Jump Securities Based on the Value of the Class A Common Stock of Snowflake Inc. due June 25, 2025

Principal at Risk Securities

The original issue price of each security is $1,000. This price includes costs associated with issuing, selling, structuring and hedging the securities, which are borne by you, and, consequently, the estimated value of the securities on the pricing date will be less than $1,000. We estimate that the value of each security on the pricing date will be approximately $977.00, or within $25.00 of that estimate. Our estimate of the value of the securities as determined on the pricing date will be set forth in the final pricing supplement.

What goes into the estimated value on the pricing date?

In valuing the securities on the pricing date, we take into account that the securities comprise both a debt component and a performance-based component linked to the underlying stock. The estimated value of the securities is determined using our own pricing and valuation models, market inputs and assumptions relating to the underlying stock, instruments based on the underlying stock, volatility and other factors including current and expected interest rates, as well as an interest rate related to our secondary market credit spread, which is the implied interest rate at which our conventional fixed rate debt trades in the secondary market.

What determines the economic terms of the securities?

In determining the economic terms of the securities, including the upside payment and the downside threshold level, we use an internal funding rate, which is likely to be lower than our secondary market credit spreads and therefore advantageous to us. If the issuing, selling, structuring and hedging costs borne by you were lower or if the internal funding rate were higher, one or more of the economic terms of the securities would be more favorable to you.

What is the relationship between the estimated value on the pricing date and the secondary market price of the securities?

The price at which MS & Co. purchases the securities in the secondary market, absent changes in market conditions, including those related to the underlying stock, may vary from, and be lower than, the estimated value on the pricing date, because the secondary market price takes into account our secondary market credit spread as well as the bid-offer spread that MS & Co. would charge in a secondary market transaction of this type and other factors. However, because the costs associated with issuing, selling, structuring and hedging the securities are not fully deducted upon issuance, for a period of up to 6 months following the issue date, to the extent that MS & Co. may buy or sell the securities in the secondary market, absent changes in market conditions, including those related to the underlying stock, and to our secondary market credit spreads, it would do so based on values higher than the estimated value. We expect that those higher values will also be reflected in your brokerage account statements.

MS & Co. may, but is not obligated to, make a market in the securities, and, if it once chooses to make a market, may cease doing so at any time.

Key Investment Rationale

This 54-week investment does not pay interest or dividends but offers a fixed positive return of 21.90% if the final share price, as measured on the five averaging dates, is greater than or equal to the downside threshold level and limited protection against a decline in the underlying stock of up to 30%. However, if, as of the averaging dates, the value of the underlying stock has declined by more than 30% from the initial share price, the payment at maturity per security will be less than $700 and could be zero.

Upside Scenario

If the final share price, as measured on the five averaging dates, is greater than or equal to the downside threshold level, the payment at maturity for each security will be equal to $1,000 plus the upside payment of $219.00‬.

Downside Scenario

If the final share price, as measured on the five averaging dates, is less than the downside threshold level, which means that the underlying stock has depreciatedby more than 30% from its initial share price, you will lose 1% for every 1% decline in the value of the underlying stock from the initial share price (e.g., a 50% depreciation in the underlying stock will result in a payment at maturity of $500 per security).

How the Trigger Jump Securities Work

Payoff Diagram

The payoff diagram and table below illustrate the payout on the securities at maturity for a range of hypothetical percentage changes in the underlying stock. The diagram is based on the following terms:

Stated principal amount:	$1,000 per security
Upside payment:	$219.00‬ per security (21.90% of the stated principal amount)
Downside threshold level:	70% of the initial share price (-30% change in final share price compared with initial share price)

Trigger Jump Securities Payoff Diagram

How it works

◼Upside Scenario. If the final share price, as measured on the five averaging dates, is greater than or equal to the downside threshold level, the investor would receive $1,000 plus the upside payment of $219.00‬.

◼Downside Scenario. If the final share price, as measured on the five averaging dates, is less than the downside threshold level, the payment at maturity would be less than the stated principal amount of $1,000 by an amount that is proportionate to the full percentage decrease of the underlying stock.

oFor example, if the final share price declines by 50% from the initial share price, the payment at maturity would be $500 per security (50% of the stated principal amount).

Payoff Table

The “Return on Securities” as used in this preliminary pricing supplement is the number, expressed as a percentage, that results from comparing the payment at maturity per $1,000 principal amount security to $1,000. The hypothetical returns set forth below reflect the upside payment of $219.00 per security and the downside threshold level of 70% of the initial share price and assume an initial share price of $100.00. The actual initial share price is set forth on the cover of this document. The hypothetical returns set forth below are for illustrative purposes only and may not reflect the actual returns applicable to a purchaser of the securities.

Final Share Price ($)	Percentage Change from Initial Share Price	Return on Securities

Hypothetical Examples of Amounts Payable at Maturity

Example 1: The price of the underlying stock increases from the initial share price of $100.00 to a final share price of $130.00. Because the final share price is greater than the downside threshold level of 70% of the initial share price, the investor receives $1,000 plus the upside payment of $219.00, a return on the securities of 21.90%, but does not participate in the appreciation of the underlying stock.

Example 2: The price of the underlying stock decreases from the initial share price of $100.00 to a final share price of $60.00. Because the final share price is less than the downside threshold level of 70% of the initial share price, the investor receives a payment at maturity that is less than the stated principal amount of $1,000 by an amount proportionate to the full percentage decrease of the underlying stock, calculated as follows:

$1,000 × share performance factor

$1,000 × ($60.00 / $100.00) = $600.00

Example 3: The price of the underlying stock decreases from the initial share price of $100.00 to a final share price of $90.00. Because the final share price is greater than the downside threshold level of 70% of the initial share price, the investor receives $1,000 plus the upside payment of $219.00, a return on the securities of 21.90%.

Risk Factors

This section describes the material risks relating to the securities. For further discussion of these and other risks, you should read the section entitled “Risk Factors” in the accompanying product supplement and prospectus. We also urge you to consult with your investment, legal, tax, accounting and other advisers in connection with your investment in the securities.

Risks Relating to an Investment in the Securities

￭The securities do not pay interest or guarantee any return of principal. The terms of the securities differ from those of ordinary debt securities in that the securities do not pay interest or guarantee payment of any of the principal amount at maturity. At maturity, you will receive for each $1,000 stated principal amount of securities that you hold an amount in cash based upon the final share price. If the final share price, as measured on the five averaging dates, is less than the downside threshold level, you will receive an amount in cash that is significantly less than the $1,000 stated principal amount of each security by an amount proportionate to the full decline in the value of the underlying stock from the initial share price to the final share price, and you will lose a significant portion or all of your investment. There is no minimum payment at maturity on the securities, and, accordingly, you could lose your entire investment. See “How the Trigger Jump Securities Work” above.

￭The appreciation potential is fixed and limited. Where the final share price, as measured on the five averaging dates, is greater than or equal to the downside threshold level, the appreciation potential of the securities is limited to the upside payment of $219.00‬ per security (21.90% of the stated principal amount), even if the final share price is significantly greater than the initial share price.

￭The market price of the securities may be influenced by many unpredictable factors. Several factors, many of which are beyond our control, will influence the value of the securities in the secondary market and the price at which MS & Co. may be willing to purchase or sell the securities in the secondary market, including:

￭the value of the underlying stock at any time (including in relation to the downside threshold level),

￭the volatility (frequency and magnitude of changes in value) of the underlying stock,

￭dividend rates on the underlying stock,

￭interest and yield rates in the market,

￭geopolitical conditions and economic, financial, political, regulatory or judicial events that affect the underlying stock or stock markets generally and which may affect the price of the underlying stock,

￭the time remaining until the maturity of the securities,

￭the occurrence of certain events affecting the underlying stock that may or may not require an adjustment to the adjustment factor, and

￭any actual or anticipated changes in our credit ratings or credit spreads.

Some or all of these factors will influence the price you will receive if you sell your securities prior to maturity. For example, you may have to sell your securities at a substantial discount from the stated principal amount if at the time of sale the price of the underlying stock is at or below the initial share price and especially if it is near or below the downside threshold level.

You cannot predict the future performance of the underlying stock based on its historical performance. The underlying stock began trading on September 16, 2020 and therefore has limited historical performance. If the final share price is less than the downside threshold level, you will be exposed on a 1-to-1 basis to the full decline in the final share price from the initial share price. There can be no assurance that the final share price will be greater than or equal to the downside threshold level so that you will receive at maturity an amount that is greater than the $1,000 stated principal amount for each security you hold, or that you will not lose a significant portion or all of your investment.

June 2024Page 7

Morgan Stanley Finance LLC

Enhanced Trigger Jump Securities Based on the Value of the Class A Common Stock of Snowflake Inc. due June 25, 2025

Principal at Risk Securities

￭The securities are subject to our credit risk, and any actual or anticipated changes to our credit ratings or credit spreads may adversely affect the market value of the securities. You are dependent on our ability to pay all amounts due on the securities at maturity and therefore you are subject to our credit risk. If we default on our obligations under the securities, your investment would be at risk and you could lose some or all of your investment. As a result, the market value of the securities prior to maturity will be affected by changes in the market’s view of our creditworthiness. Any actual or anticipated decline in our credit ratings or increase in the credit spreads charged by the market for taking our credit risk is likely to adversely affect the market value of the securities.

￭As a finance subsidiary, MSFL has no independent operations and will have no independent assets. As a finance subsidiary, MSFL has no independent operations beyond the issuance and administration of its securities and will have no independent assets available for distributions to holders of MSFL securities if they make claims in respect of such securities in a bankruptcy, resolution or similar proceeding. Accordingly, any recoveries by such holders will be limited to those available under the related guarantee by Morgan Stanley and that guarantee will rank pari passu with all other unsecured, unsubordinated obligations of Morgan Stanley. Holders will have recourse only to a single claim against Morgan Stanley and its assets under the guarantee. Holders of securities issued by MSFL should accordingly assume that in any such proceedings they would not have any priority over and should be treated pari passu with the claims of other unsecured, unsubordinated creditors of Morgan Stanley, including holders of Morgan Stanley-issued securities.

￭The amount payable on the securities is not linked to the value of the underlying stock at any time other than the averaging dates. The final share price will be the arithmetic average of the closing prices of the underlying stock on each of the five averaging dates, subject to postponement for non-trading days and certain market disruption events. Even if the value of the underlying stock appreciates prior to the averaging dates but then drops by the averaging dates, the payment at maturity may be significantly less than it would have been had the payment at maturity been linked to the value of the underlying stock prior to such drop. Although the actual value of the underlying stock on the stated maturity date or at other times during the term of the securities may be higher than the final share price, the payment at maturity will be based solely on the final share price of the underlying stock, as determined on the five averaging dates.

￭The rate we are willing to pay for securities of this type, maturity and issuance size is likely to be lower than the rate implied by our secondary market credit spreadsand advantageous to us. Both the lower rate and the inclusion of costs associated with issuing, selling, structuring and hedging the securities in the original issue price reduce the economic terms of the securities, cause the estimated value of the securities to be less than the original issue price and will adversely affect secondary market prices. Assuming no change in market conditions or any other relevant factors, the prices, if any, at which dealers, including MS & Co., may be willing to purchase the securities in secondary market transactions will likely be significantly lower than the original issue price, because secondary market prices will exclude the issuing, selling, structuring and hedging-related costs that are included in the original issue price and borne by you and because the secondary market prices will reflect our secondary market credit spreads and the bid-offer spread that any dealer would charge in a secondary market transaction of this type as well as other factors.

The inclusion of the costs of issuing, selling, structuring and hedging the securities in the original issue price and the lower rate we are willing to pay as issuer make the economic terms of the securities less favorable to you than they otherwise would be.

However, because the costs associated with issuing, selling, structuring and hedging the securities are not fully deducted upon issuance, for a period of up to 6 months following the issue date, to the extent that MS & Co. may buy or sell the securities in the secondary market, absent changes in market conditions, including those related to the underlying stock, and to our secondary market credit spreads, it would do so based on values higher than the estimated value, and we expect that those higher values will also be reflected in your brokerage account statements.

￭The estimated value of the securities is determined by reference to our pricing and valuation models, which may differ from those of other dealers and is not a maximum or minimum secondary market price. These pricing and valuation models are proprietary and rely in part on subjective views of certain market inputs and certain assumptions about future events, which may prove to be incorrect. As a result, because there is no market-standard way to value these types of securities, our models may yield a higher estimated value of the

June 2024Page 8

Morgan Stanley Finance LLC

Enhanced Trigger Jump Securities Based on the Value of the Class A Common Stock of Snowflake Inc. due June 25, 2025

Principal at Risk Securities

securities than those generated by others, including other dealers in the market, if they attempted to value the securities. In addition, the estimated value on the pricing date does not represent a minimum or maximum price at which dealers, including MS & Co., would be willing to purchase your securities in the secondary market (if any exists) at any time. The value of your securities at any time after the date of this document will vary based on many factors that cannot be predicted with accuracy, including our creditworthiness and changes in market conditions. See also “The market price of the securities may be influenced by many unpredictable factors” above.

￭The securities will not be listed on any securities exchange and secondary trading may be limited. The securities will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the securities. Morgan Stanley & Co. LLC, which we refer to as MS & Co., may, but is not obligated to, make a market in the securities and, if it once chooses to make a market, may cease doing so at any time. When it does make a market, it will generally do so for transactions of routine secondary market size at prices based on its estimate of the current value of the securities, taking into account its bid/offer spread, our credit spreads, market volatility, the notional size of the proposed sale, the cost of unwinding any related hedging positions, the time remaining to maturity and the likelihood that it will be able to resell the securities. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the securities easily. Since other broker-dealers may not participate significantly in the secondary market for the securities, the price at which you may be able to trade your securities is likely to depend on the price, if any, at which MS & Co. is willing to transact. If, at any time, MS & Co. were to cease making a market in the securities, it is likely that there would be no secondary market for the securities. Accordingly, you should be willing to hold your securities to maturity.

￭Investing in the securities is not equivalent to investing in the class A common stock of Snowflake Inc. Investors in the securities will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the underlying stock. As a result, any return on the securities will not reflect the return you would realize if you actually owned shares of the underlying stock and received the dividends paid or distributions made on them.

￭The calculation agent, which is a subsidiary of Morgan Stanley and an affiliate of MSFL, will make determinations with respect to the securities. As calculation agent, MS & Co. will determine the initial share price, the downside threshold level, the final share price, whether a market disruption event has occurred or any antidilution adjustment will be made, the share performance factor, if applicable, and the payment that you will receive at maturity, if any. Moreover, certain determinations made by MS & Co., in its capacity as calculation agent, may require it to exercise discretion and make subjective judgments, such as with respect to the occurrence or non-occurrence of market disruption events and the calculation of the final share price (and of any antidilution adjustments). These potentially subjective determinations may adversely affect the payout to you at maturity, if any. For further information regarding these types of determinations, see “Description of Securities—Postponement of Valuation Date(s),” “—Antidilution Adjustments,” “—Alternate Exchange Calculation in case of an Event of Default” and “—Calculation Agent and Calculations” in the accompanying product supplement for Jump Securities. In addition, MS & Co. has determined the estimated value of the securities on the pricing date.

￭Hedging and trading activity by our affiliates could potentially adversely affect the value of the securities.
One or more of our affiliates and/or third-party dealers expect to carry out hedging activities related to the securities (and to other instruments linked to the underlying stock), including trading in the underlying stock and in options contracts on the underlying stock, as well as in other instruments related to the underlying stock. As a result, these entities may be unwinding or adjusting hedge positions during the term of the securities, and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the averaging dates approach. Some of our affiliates also trade the underlying stock and other financial instruments related to underlying stock on a regular basis as part of their general broker-dealer and other businesses.  Any of these hedging or trading activities on or prior to June 6, 2024 could potentially increase the initial share price, and, therefore, the value at or above which the underlying stock must close on the averaging dates so that investors do not suffer a significant loss on their initial investment in the securities.  Additionally, such hedging or trading activities during the term of the securities, including on the averaging dates, could adversely affect the closing price of the underlying stock on the averaging dates, and, accordingly, the amount of cash you will receive at maturity, if any.

￭The U.S. federal income tax consequences of an investment in the securities are uncertain. Please read the discussion under “Additional Information—Tax considerations” in this document and the discussion under “United States Federal Taxation” in the accompanying product supplement for Jump Securities(together, the “Tax Disclosure Sections”) concerning the U.S. federal income tax consequences of an investment in the securities. There is no direct legal authority regarding the proper U.S. federal tax treatment of the securities, and we do not plan to request a ruling from the Internal Revenue Service (the “IRS”). Consequently, significant aspects of the tax treatment of the securities are uncertain, and the IRS or a court might not agree with the tax treatment of a security as a single financial contract that is an “open transaction” for U.S. federal income tax purposes. If the IRS were successful in asserting an alternative treatment of the securities, the tax consequences of the ownership and disposition of the securities, including the timing and character of income recognized by U.S. Holders and the withholding tax consequences to Non-U.S. Holders, might be materially and adversely affected. For example, there is a risk (which, depending on the market conditions on the pricing date, could be substantial) that the IRS could seek to recharacterize the securities as debt instruments. Moreover, future legislation, Treasury regulations or IRS guidance could adversely affect the U.S. federal tax treatment of the securities, possibly retroactively.

Both U.S. and Non-U.S. Holders should consult their tax advisers regarding the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments, as well as any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

We have not made any due diligence inquiry with respect to Snowflake Inc. in connection with this offering.

￭We may engage in business with or involvingSnowflake Inc. without regard to your interests. We or our affiliates may presently or from time to time engage in business with Snowflake Inc. without regard to your interests and thus may acquire non-public information about Snowflake Inc. Neither we nor any of our affiliates undertakes to disclose any such information to you. In addition, we or our affiliates from time to time have published and in the future may publish research reports with respect to Snowflake Inc., which may or may not recommend that investors buy or hold the underlying stock.

￭The antidilution adjustments the calculation agent is required to make do not cover every corporate event that could affect the underlying stock. MS & Co., as calculation agent, will adjust the adjustment factor for certain corporate events affecting the underlying stock, such as stock splits, stock dividends and extraordinary dividends, and for certain other corporate actions involving the underlying stock. However, the calculation agent will not make an adjustment for every corporate event or every distribution that could affect the underlying stock. In addition, no adjustments will be made for regular cash dividends, which are expected to reduce the price of the underlying stock by the amount of such dividends. If an event occurs that does not require the calculation agent to adjust the adjustment factor, such as a regular cash dividend, the market price of the securities and your return on the securities may be materially and adversely affected. The determination by the calculation agent to adjust, or not to adjust, an adjustment factor may materially and adversely affect the market price of the securities. For example, if the record date for a regular cash dividend were to occur on or shortly before the averaging dates, this may decrease the final share price to be less than the downside threshold level (resulting in a loss of a significant portion or all of your investment in the securities), materially and adversely affecting your return.

Additional Information About the Securities

Additional Information:
Minimum ticketing size:	$1,000 / 1 security
Tax considerations:	There is uncertainty regarding the U.S. federal income tax consequences of an investment in the securities due to the lack of governing authority. Our counsel, Davis Polk & Wardwell LLP, is unable to render a definitive opinion on the tax treatment of the securities at this time as such opinion is dependent in part upon market conditions on the pricing date. Our counsel’s opinion will therefore be provided only on the pricing date. However, under current law, and based on current market conditions, our counsel believes that it is at least reasonable to treat a security as a single financial contract that is an “open transaction” for U.S. federal income tax purposes. Assuming this treatment of the securities is respected and subject to the discussion in “United States Federal Taxation” in the accompanying product supplement for Jump Securities, the following U.S. federal income tax consequences should result based on current law: ￭A U.S. Holder should not be required to recognize taxable income over the term of the securities prior to settlement, other than pursuant to a sale or exchange. ￭Upon sale, exchange or settlement of the securities, a U.S. Holder should recognize gain or loss equal to the difference between the amount realized and the U.S. Holder’s tax basis in the securities. Such gain or loss should be long-term capital gain or loss if the investor has held the securities for more than one year, and short-term capital gain or loss otherwise. There is a risk that the Internal Revenue Service (the “IRS”) may seek to treat all or a portion of the gain on the securities as ordinary income. For example, there is a risk (which, depending on the market conditions on the pricing date, could be substantial) that the IRS could seek to recharacterize the securities as debt instruments. In that event, U.S. Holders would be required to accrue into income original issue discount on the securities every year at a “comparable yield” determined at the time of issuance and recognize all income and gain in respect of the securities as ordinary income. We do not plan to request a ruling from the IRS regarding the treatment of the securities. An alternative characterization of the securities could materially and adversely affect the tax consequences of ownership and disposition of the securities, including the timing and character of income recognized. In addition, the U.S. Treasury Department and the IRS have requested comments on various issues regarding the U.S. federal income tax treatment of “prepaid forward contracts” and similar financial instruments and have indicated that such transactions may be the subject of future regulations or other guidance. Furthermore, members of Congress have proposed legislative changes to the tax treatment of derivative contracts. Any legislation, Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, possibly with retroactive effect. As discussed in the accompanying product supplement for Jump Securities, Section 871(m) of the Internal Revenue Code of 1986, as amended, and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% (or a lower applicable treaty rate) withholding tax 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 (each, an “Underlying Security”). Subject to certain exceptions, Section 871(m) generally applies to securities that substantially replicate the economic performance of one or more Underlying Securities, as determined based on tests set forth in the applicable Treasury regulations (a “Specified Security”). However, pursuant to an IRS notice, Section 871(m) will not apply to securities issued before January 1, 2027 that do not have a delta of one with respect to any Underlying Security. Based on the terms of the securities and current market conditions, we expect that the securities will not have a delta of one with respect to any Underlying Security on the pricing date. However, we will provide an updated determination in the final pricing supplement. Assuming that the securities do not have a delta of one with respect to any Underlying Security, our counsel is of the opinion that the securities should not be Specified Securities and, therefore, should not be subject to Section 871(m). 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 withholding is required, we will not be required to pay any additional amounts with respect to the amounts so withheld. You should consult your tax adviser regarding the potential application of Section 871(m) to the securities. Both U.S. and non-U.S. investors considering an investment in the securities should read the discussion under “Risk Factors” in this document and the discussion under “United States Federal Taxation” in the accompanying product supplement for Jump Securities and consult their tax advisers regarding all aspects of the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments, and any tax consequences arising under

	the laws of any state, local or non-U.S. taxing jurisdiction. The discussion in the preceding paragraphs under “Tax considerations” and the discussion contained in the section entitled “United States Federal Taxation” in the accompanying product supplement for Jump Securities, insofar as they purport to describe provisions of U.S. federal income tax laws or legal conclusions with respect thereto, constitute the full opinion of Davis Polk & Wardwell LLP regarding the material U.S. federal tax consequences of an investment in the securities.
Use of proceeds and hedging:	The proceeds from the sale of the securities will be used by us for general corporate purposes. We will receive, in aggregate, $1,000 per security issued. The costs of the securities borne by you and described beginning on page 3 above comprise the cost of issuing, structuring and hedging the securities. On or prior to June 6, 2024, we will hedge our anticipated exposure in connection with the securities by entering into hedging transactions with our affiliates and/or third-party dealers. We expect our hedging counterparties to take positions in the underlying stock, in futures and/or options contracts on the underlying stock, or positions in any other available securities or instruments that they may wish to use in connection with such hedging. Such purchase activity could potentially increase the value of the underlying stock on June 6, 2024, and, therefore, could increase the value at or above which the underlying stock must close on the averaging dates so that investors do not suffer a significant loss on their initial investment in the securities. In addition, through our affiliates, we are likely to modify our hedge position throughout the term of the securities, including on the averaging dates, by purchasing and selling the underlying stock, futures or options contracts on the underlying stock or positions in any other available securities or instruments that we may wish to use in connection with such hedging activities. As a result, these entities may be unwinding or adjusting hedge positions during the term of the securities, and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the averaging dates approach. We cannot give any assurance that our hedging activities will not affect the value of the underlying stock, and, therefore, adversely affect the value of the securities or the payment you will receive at maturity, if any. For further information on our use of proceeds and hedging, see “Use of Proceeds and Hedging” in the accompanying product supplement.
Additional considerations:	Client accounts over which Morgan Stanley, Morgan Stanley Wealth Management or any of their respective subsidiaries have investment discretion are not permitted to purchase the securities, either directly or indirectly.
Supplemental information regarding plan of distribution; conflicts of interest:	JPMorgan Chase Bank, N.A., J.P. Morgan Securities LLC and its affiliates will act as placement agents for the securities and will receive a fee from the Issuer or one of its affiliates that will not exceed $10 per $1,000 stated principal amount of securities, but will forgo any fees for sales to certain fiduciary accounts. MS & Co. is an affiliate of MSFL and a wholly owned subsidiary of Morgan Stanley, and it and other affiliates of ours expect to make a profit by selling, structuring and, when applicable, hedging the securities. When MS & Co. prices this offering of securities, it will determine the economic terms of the securities such that for each security the estimated value on the pricing date will be no lower than the minimum level described in “Investment Summary” beginning on page 2. MS & Co. will conduct this offering in compliance with the requirements of FINRA Rule 5121 of the Financial Industry Regulatory Authority, Inc., which is commonly referred to as FINRA, regarding a FINRA member firm’s distribution of the securities of an affiliate and related conflicts of interest. MS & Co. or any of our other affiliates may not make sales in this offering to any discretionary account. See “Plan of Distribution (Conflicts of Interest)” and “Use of Proceeds and Hedging” in the accompanying product supplement.
