Dual Directional Trigger Jump Securities Based on the Performance of the EURO STOXX 50® Index due November 19, 2029

Fully and Unconditionally Guaranteed by Morgan Stanley

Principal at Risk Securities

The Dual Directional Trigger Jump Securities (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, do not guarantee any return of principal at maturity and have the terms described in the accompanying product supplement for Jump Securities, index supplement and prospectus, as supplemented or modified by this document. At maturity, if the EURO STOXX 50® Index, which we refer to as the underlying index, has appreciated in value by no more than 64%, you will receive for each security that you hold at maturity the stated principal amount of $1,000 plus $640. If the underlying index has appreciated by more than 64%, you will receive for each security that you hold at maturity the stated principal amount plus an amount based on the percentage increase of the underlying index. If the underlying index has depreciated in value but by no more than 15%, you will receive the stated principal amount of your investment plus a positive return equal to the absolute value of the percentage decline, which will effectively be limited to a positive return of 15%. However, if the underlying index has depreciated by more than 15%, you will be negatively exposed to the full amount of the percentage decline in the underlying index and will lose 1% of the stated principal amount for every 1% of decline, without any buffer. These long-dated securities are for investors who seek an equity index-based return and who are willing to risk their principal and forgo current income in exchange for the upside payment and absolute return features that in each case apply to a limited range of performance of the underlying index. Investors may lose their entire initial investment in the securities. The securities are notes issued as part of MSFL’s Series A Global Medium-Term Notes program. The securities differ from the Jump Securities described in the accompanying product supplement for Jump Securities in that the securities offer the potential for a positive return at maturity if the underlying index depreciates by up to 15%. The securities are not the Buffered Jump Securities described in the accompanying product supplement for Jump Securities. Unlike the Buffered Jump Securities, the securities do not provide any protection if the underlying index depreciates by more than 15%.

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.

Investment Summary

Dual Directional Trigger Jump Securities

The Dual Directional Trigger Jump Securities Based on the Performance of the EURO STOXX 50® Index due November 19, 2029 (the “securities”) can be used:

￭As an alternative to direct exposure to the underlying index that provides a minimum positive return of 64% if the underlying index has appreciated at all as of the valuation date and offers an uncapped 1-to-1 participation in the appreciation of the underlying index of greater than 64%.

￭To obtain a positive return for a limited range of negative performance of the underlying index.

￭To potentially outperform the underlying index in a moderately bullish or moderately bearish scenario.

If the final index value is less than the trigger level, the securities are exposed on a 1:1 basis to the percentage decline of the final index value from the initial index value. Accordingly, investors may lose their entire initial investment in the securities.

Maturity:	5 years
Upside payment:	$640 per security (64% of the stated principal amount)
Minimum payment at maturity:	None
Trigger level:	85% of the initial index value
Coupon:	None
Listing:	The securities will not be listed on any securities exchange

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 is less than $1,000. We estimate that the value of each security on the pricing date is $953.10.

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 index. The estimated value of the securities is determined using our own pricing and valuation models, market inputs and assumptions relating to the underlying index, instruments based on the underlying index, 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 trigger 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 index, 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 index, 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

The securities offer the potential for a positive return at maturity based on the absolute value of a limited range of the percentage change of the underlying index. At maturity, if the underlying index has appreciated in value by no more than 64%, investors will receive the minimum positive return of 64%. If the underlying index has appreciated in value by more than 64%, investors will participate on a 1:1 basis in the appreciation of the underlying index. If the underlying index has depreciated in value but by no more than 15%, investors will receive the stated principal amount of their investment plus a positive return equal to the absolute value of the percentage decline, which will effectively be limited to a positive return of 15%. However, if the underlying index has depreciated by more than 15%, investors will be negatively exposed to the full amount of the percentage decline in the underlying index and will lose 1% of the stated principal amount for every 1% of decline, without any buffer. Investors may lose their entire initial investment in the securities. All payments on the securities are subject to our credit risk.

Absolute Return Feature	The securities enable investors to obtain a positive return if the final index value is less than the initial index value but is greater than or equal to the trigger level.
Upside Scenario if the Underlying Index Appreciates	The final index value is greater than or equal to the initial index value. In this case, you receive for each security that you hold $1,000 plus the greater of (i) $1,000 multiplied by the index percent change and (ii) the upside payment of $640 (64% of the stated principal amount). There is no maximum payment at maturity.
Absolute Return Scenario	The final index value is less than the initial index value but is greater than or equal to the trigger level, which is 85% of the initial index value. In this case, you receive a 1% positive return on the securities for each 1% negative return on the underlying index. For example, if the final index value is 5% less than the initial index value, the securities will provide a positive return of 5% at maturity. The maximum return you may receive in this scenario is a positive 15% return at maturity.
Downside Scenario	The final index value is less than the trigger level. In this case, the securities redeem for at least 15% less than the stated principal amount, and this decrease will be by an amount proportionate to the decline in the value of the underlying index over the term of the securities. Under these circumstances, the payment at maturity will be less than $850 per security. For example, if the final index value is 35% less than the initial index value, the securities will be redeemed at maturity for a loss of 35% of principal at $650, or 65% of the stated principal amount. There is no minimum payment at maturity on the securities, and investors may lose their entire initial investment.

How it works

￭Upside Scenario if the Underlying Index Appreciates. Under the terms of the securities, if the final index value is greater than or equal to the initial index value, the investor would receive the $1,000 stated principal amount plus the greater of (i) $1,000 multiplied by the index percent change and (ii) the upside payment of $640.

￭If the underlying index appreciates 10%, the investor would receive a 64% return, or $1,640 per security.

￭If the underlying index appreciates 110%, the investor would receive a 110% return, or $2,100 per security. There is no maximum payment at maturity on the securities.

￭Absolute Return Scenario. If the final index value is less than the initial index value and is greater than or equal to the trigger level of 85% of the initial index value, the investor would receive a 1% positive return on the securities for each 1% negative return on the underlying index.

￭If the underlying index depreciates 5%, the investor would receive a 5% return, or $1,050 per security.

￭The maximum return you may receive in this scenario is a positive 15% return at maturity.

￭Downside Scenario. If the final index value is less than the trigger level, the investor would receive an amount significantly less than the $1,000 stated principal amount, based on a 1% loss of principal for each 1% decline in the underlying index. Under these circumstances, the payment at maturity will be less than $850 per security. There is no minimum payment at maturity on the securities.

￭If the underlying index depreciates 40%, the investor would lose 40% of the investor’s principal and receive only $600 per security at maturity, or 60% of the stated principal amount.

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 for Jump Securities, index supplement and prospectus. We also urge you to consult 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 return of any principal. The terms of the securities differ from those of ordinary debt securities in that the securities do not pay interest or guarantee the payment of any principal amount at maturity. If the final index value is less than the trigger level (which is 85% of the initial index value), the absolute return feature will no longer be available and the payout at maturity will be an amount in cash that is at least 15% less than the $1,000 stated principal amount of each security, and this decrease will be by an amount proportionate to the full amount of the decline in the value of the underlying index over the term of the securities, without any buffer. There is no minimum payment at maturity on the securities, and, accordingly, you could lose your entire initial investment in the securities.

￭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:

othe value of the underlying index at any time (including in relation to the trigger level),

othe volatility (frequency and magnitude of changes in value) of the underlying index,

odividend rates on the securities underlying the underlying index,

ointerest and yield rates in the market,

ogeopolitical conditions and economic, financial, political, regulatory or judicial events that affect the component stocks of the underlying index or securities markets generally and which may affect the value of the underlying index,

othe time remaining until the maturity of the securities,

othe composition of the underlying index and changes in the constituent stocks of the underlying index, and

oany actual or anticipated changes in our credit ratings or credit spreads.

Generally, the longer the time remaining to maturity, the more the market price of the securities will be affected by the other factors described above. 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 value of the underlying index is at or below the initial index value and especially if it is near or below the trigger level.

You cannot predict the future performance of the underlying index based on its historical performance. If the final index value is less than the trigger level, you will be exposed on a 1-to-1 basis to the full decline in the final index value from the initial index value.

￭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 index at any time other than the valuation date. The final index value will be the index closing value on the valuation date, subject to postponement for non-index business days and certain market disruption events. Even if the value of the underlying index appreciates prior to the valuation date but then drops by the valuation date to be below the trigger level, the payment at maturity will be significantly less than it would have been had the payment at maturity been linked to the value of the underlying index prior to such drop. Although the

November 2024 Page 6

Morgan Stanley Finance LLC

Dual Directional Trigger Jump Securities Based on the Performance of the EURO STOXX 50® Index due November 19, 2029

Principal at Risk Securities

actual value of the underlying index on the stated maturity date or at other times during the term of the securities may be higher than the final index value, the payment at maturity will be based solely on the index closing value on the valuation date.

￭Investing in the securities is not equivalent to investing in the underlying index. Investing in the securities is not equivalent to investing in the underlying index or its component stocks. 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 stocks that constitute the underlying index.

￭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 spreads and 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 index, 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 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.

￭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 index value, the trigger level and the final index value, including whether the value of the underlying index has decreased to below the trigger level, and will calculate the amount of cash you 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 selection of a successor index or calculation of the final index value in the event of a market disruption event or discontinuance of the underlying index.  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),” “—Discontinuance of Any Underlying Index or Basket Index; Alteration of Method of Calculation,” “—Alternate Exchange Calculation in case of an Event of Default” and “—Calculation Agent and Calculations” in the accompanying product supplement.  In addition, MS & Co. has determined the estimated value of the securities on the pricing date.

Principal at Risk Securities

￭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 index or its component stocks), including trading in the stocks that constitute the underlying index as well as in other instruments related to the underlying index. 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 valuation date approaches. Some of our affiliates also trade the stocks that constitute the underlying index and other financial instruments related to the underlying index 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 the pricing date could potentially increase the initial index value, and, therefore, the value at or above which the underlying index must close on the valuation date 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 valuation date, could adversely affect the value of the underlying index on the valuation date, and, accordingly, the amount of cash an investor 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. 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.

Risks Relating to the Underlying Index

￭There are risks associated with investments in securities linked to the value of foreign equity securities. The securities are linked to the value of foreign equity securities. Investments in securities linked to the value of foreign equity securities involve risks associated with the securities markets in those countries, including risks of volatility in those markets, governmental intervention in those markets and cross-shareholdings in companies in certain countries. Also, there is generally less publicly available information about foreign companies than about U.S. companies that are subject to the reporting requirements of the United States Securities and Exchange Commission, and foreign companies are subject to accounting, auditing and financial reporting standards and requirements different from those applicable to U.S. reporting companies. The prices of securities issued in foreign markets may be affected by political, economic, financial and social factors in those countries, or global regions, including changes in government, economic and fiscal policies and currency exchange laws. Local securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times. Moreover, the economies in such countries may differ favorably or unfavorably from the economy in the United States in such respects as growth of gross national product, rate of inflation, capital reinvestment, resources, self-sufficiency and balance of payment positions between countries.

￭Adjustments to the underlying index could adversely affect the value of the securities. The underlying index publisher may add, delete or substitute the stocks constituting the underlying index or make other methodological changes that could change the value of the underlying index. The underlying index publisher may discontinue or suspend calculation or publication of the underlying index at any time. In these circumstances, the calculation agent will have the sole discretion to substitute a successor index that is comparable to the discontinued underlying index and will be permitted to consider indices that are calculated and published by the calculation agent or any of its affiliates.

Additional Information About the Securities

Additional Information:
Minimum ticketing size:	$1,000 / 1 security
Tax considerations:	Although there is uncertainty regarding the U.S. federal income tax consequences of an investment in the securities due to the lack of governing authority, in the opinion of our counsel, Davis Polk & Wardwell LLP, under current law, and based on current market conditions, it is 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. We do not plan to request a ruling from the Internal Revenue Service (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 our determination 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, because, when we enter into hedging transactions in order to meet our obligations under the securities, our hedging counterparty will reimburse the cost of the agent’s commissions. The costs of the securities borne by you and described on page 2 above comprise the agent’s commissions and the cost of issuing, structuring and hedging the securities. On or prior to the pricing date, 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 stocks constituting the underlying index and in futures and/or options contracts on the underlying index or its component stocks listed on major securities markets, 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 index on the pricing date, and, therefore, could increase the value at or above which the underlying index must close on the valuation date 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 valuation date, by purchasing and selling the stocks constituting the underlying index, futures or options contracts on the underlying index or its component stocks listed on major securities markets 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 valuation date approaches. We cannot give any assurance that our hedging activities will not affect the value of the underlying index, 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 $30 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. 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.
Validity of the securities:	In the opinion of Davis Polk & Wardwell LLP, as special counsel to MSFL and Morgan Stanley, when the securities offered by this pricing supplement have been executed and issued by MSFL, authenticated by the trustee pursuant to the MSFL Senior Debt Indenture (as defined in the accompanying prospectus) and delivered against payment as contemplated herein, such securities will be valid and binding obligations of MSFL and the related guarantee will be a valid and binding obligation of Morgan Stanley, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability (including, without limitation, concepts of good faith, fair dealing and the lack of bad faith), provided that such counsel expresses no opinion as to (i) the effect of fraudulent conveyance, fraudulent transfer or similar provision of applicable law on the conclusions expressed above and (ii) any provision of the MSFL Senior Debt Indenture that purports to avoid the effect of fraudulent conveyance, fraudulent transfer or similar provision of applicable law by limiting the amount of Morgan Stanley’s obligation under the related guarantee. This opinion is given as of the date hereof and is limited to the laws of the State of New York, the General Corporation Law of the State of Delaware and the Delaware Limited Liability Company Act. In addition, this opinion is subject to customary assumptions about the trustee’s authorization, execution and delivery of the MSFL Senior Debt Indenture and its authentication of the securities and the validity, binding nature and enforceability of the MSFL Senior Debt Indenture with respect to the trustee, all as stated in the letter of such counsel dated February 26, 2024, which is Exhibit 5-a to Post-Effective Amendment No. 2 to the Registration Statement on Form S-3 filed by Morgan Stanley on February 26, 2024.
Where you can find more information:	MSFL and Morgan Stanley have filed a registration statement (including a prospectus, as supplemented by the product supplement for Jump Securities and the index supplement) with the Securities and Exchange Commission, or SEC, for the offering to which this communication relates. You should read the prospectus in that registration statement, the product supplement for Jump Securities, the index supplement and any other documents relating to this offering that MSFL and Morgan Stanley have filed with the SEC for more complete information about MSFL, Morgan Stanley and this offering.
