Dual Directional Trigger PLUS Based on the Performance of the Tokyo Stock Price Index due December 17, 2026

Trigger Performance Leveraged Upside SecuritiesSM

Fully and Unconditionally Guaranteed by Morgan Stanley

Principal at Risk Securities

The Dual Directional Trigger PLUS, or "Trigger PLUS," are unsecured obligations of Morgan Stanley Finance LLC ("MSFL") and are fully and unconditionally guaranteed by Morgan Stanley. The Trigger PLUS will pay no interest, do not guarantee any return of principal at maturity and have the terms described in the accompanying product supplement for PLUS, index supplement and prospectus, as supplemented or modified by this document. At maturity, if the Tokyo Stock Price Index, which we refer to as the underlying index, has appreciated in value, investors will receive the stated principal amount of their investment plus leveraged upside performance of the underlying index, subject to the maximum payment at maturity. If the underlying index has depreciated in value but by no more than 20%, investors will receive the stated principal amount of their investment plus an unleveraged positive return equal to the absolute value of the percentage decline, which will effectively be limited to a positive 20% return. However, if the underlying index has depreciated in value by more than 20%, 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. The Trigger PLUS are for investors who seek an equity index-based return and who are willing to risk their principal and forgo current income and upside above the maximum payment at maturity in exchange for the upside leverage 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 Trigger PLUS. The Trigger PLUS are notes issued as part of MSFL's Series A Global Medium-Term Notes program.

The Trigger PLUS differ from the PLUS described in the accompanying product supplement for PLUS in that the Trigger PLUS offer the potential for a positive return at maturity if the underlying index depreciates by up to 20%. The Trigger PLUS are not the Buffered PLUS described in the accompanying product supplement for PLUS. Unlike the Buffered PLUS, the Trigger PLUS do not provide any protection if the underlying index depreciates by more than 20%.

All payments are subject to our credit risk. If we default on our obligations, you could lose some or all of your investment. These Trigger PLUS 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

Trigger Performance Leveraged Upside Securities

Principal at Risk Securities

The Dual Directional Trigger PLUS Based on the Performance of the Tokyo Stock Price Index due December 17, 2026 (the "Trigger PLUS") can be used:

￭As an alternative to direct exposure to the underlying index that enhances returns for a certain range of positive performance of the underlying index, subject to the maximum payment at maturity.

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

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

Maturity:	Approximately 2 years
Leverage factor:	200% (applicable only if the final index value is greater than the initial index value).
Maximum payment at maturity:	$1,287 per Trigger PLUS (128.70% of the stated principal amount)
Minimum payment at maturity:	None. Investors may lose all their entire initial investment in the Trigger PLUS.
Trigger level:	80% of the initial index value
Coupon:	None
Listing:	The Trigger PLUS will not be listed on any securities exchange

The original issue price of each Trigger PLUS is $1,000. This price includes costs associated with issuing, selling, structuring and hedging the Trigger PLUS, which are borne by you, and, consequently, the estimated value of the Trigger PLUS on the pricing date is less than $1,000. We estimate that the value of each Trigger PLUS on the pricing date is $964.40.

What goes into the estimated value on the pricing date?

In valuing the Trigger PLUS on the pricing date, we take into account that the Trigger PLUS comprise both a debt component and a performance-based component linked to the underlying index. The estimated value of the Trigger PLUS 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 Trigger PLUS?

In determining the economic terms of the Trigger PLUS, including the leverage factor, the trigger level and the maximum payment at maturity, 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 Trigger PLUS 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 Trigger PLUS?

The price at which MS & Co. purchases the Trigger PLUS 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 Trigger PLUS 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 Trigger PLUS 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 Trigger PLUS, and, if it once chooses to make a market, may cease doing so at any time.

Key Investment Rationale

The Trigger PLUS offer the potential for a positive return at maturity based on the absolute value of a limited range of percentage changes of the underlying index. At maturity, if the underlying index has appreciated in value, investors will receive the stated principal amount of their investment plus leveraged upside performance of the underlying index, subject to the maximum payment at maturity. If the underlying index has depreciated in value but by no more than 20%, investors will receive the stated principal amount of their investment plus an unleveraged positive return equal to the absolute value of the percentage decline, which will effectively be limited to a positive 20% return. However, if the underlying index has depreciated in value by more than 20%, 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 Trigger PLUS. All payments on the Trigger PLUS are subject to our credit risk.

Leveraged Upside Performance Up to a Cap	The Trigger PLUS offer investors an opportunity to capture enhanced returns relative to a direct investment in the underlying index, subject to the maximum payment at maturity.
Absolute Return Feature	The Trigger PLUS enable investors to obtain an unleveraged positive return if the final index value is less than or equal to 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 the initial index value, and, at maturity, you receive a full return of principal as well as 200% of the increase in the value of the underlying index, subject to the maximum payment at maturity. For example, if the final index value is 5% greater than the initial index value, the Trigger PLUS will provide a total return of 10% at maturity. The maximum payment at maturity is $1,287 per Trigger PLUS (128.70% of the stated principal amount).
Absolute Return Scenario	The final index value is less than or equal to the initial index value but is greater than or equal to the trigger level, which is 80% of the initial index value. In this case, you receive a 1% positive return on the Trigger PLUS for each 1% negative return on the underlying index. For example, if the final index value is 10% less than the initial index value, the Trigger PLUS will provide a total positive return of 10% at maturity. The maximum return you may receive in this scenario is a positive 20% return at maturity.
Downside Scenario	The final index value is less than the trigger level. In this case, the Trigger PLUS redeem for at least 20% less than the stated principal amount, and this decrease will be by an amount proportionate to the full decline in the value of the underlying index over the term of the Trigger PLUS. Under these circumstances, the payment at maturity will be less than 80% of the stated principal amount per Trigger PLUS. For example, if the final index value is 70% less than the initial index value, the Trigger PLUS will be redeemed at maturity for a loss of 70% of principal at $300, or 30% of the stated principal amount. There is no minimum payment at maturity on the Trigger PLUS, and you could lose your entire investment.

How it works

￭Upside Scenario if the Underlying Index Appreciates. If the final index value is greater than the initial index value, the investor would receive the $1,000 stated principal amount plus 200% of the appreciation of the underlying index over the term of the Trigger PLUS, subject to the maximum payment at maturity. Under the terms of the Trigger PLUS, an investor would realize the maximum payment at maturity of $1,287 per Trigger PLUS (128.70% of the stated principal amount) at a final index value of 114.35% of the initial index value.

￭If the underlying index appreciates 5%, the investor would receive a 10% return, or $1,100 per Trigger PLUS.

￭If the underlying index appreciates 80%, the investor would receive only a 28.70% return or $1,287 per Trigger PLUS, due to the maximum payment at maturity.

￭Absolute Return Scenario. If the final index value is less than or equal to the initial index value and is greater than or equal to the trigger level of 80% of the initial index value, the investor would receive a 1% positive return on the Trigger PLUS for each 1% negative return on the underlying index.

￭If the underlying index depreciates 10%, the investor would receive a 10% return, or $1,100 per Trigger PLUS.

￭The maximum return you may receive in this scenario is a positive 20% return at maturity.

￭Downside Scenario. If the final index value is less than the trigger level of 80% of the initial index value, the investor would receive an amount 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 80% of the stated principal amount per Trigger PLUS. There is no minimum payment at maturity on the Trigger PLUS.

￭If the underlying index depreciates 70%, the investor would lose 70% of the investor's principal and receive only $300 per Trigger PLUS at maturity, or 30% of the stated principal amount.

Risk Factors

This section describes the material risks relating to the Trigger PLUS. For further discussion of these and other risks, you should read the section entitled "Risk Factors" in the accompanying product supplement for PLUS, 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 Trigger PLUS.

Risks Relating to an Investment in the Trigger PLUS

￭The Trigger PLUS do not pay interest or guarantee return of any principal. The terms of the Trigger PLUS differ from those of ordinary debt securities in that the Trigger PLUS 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 80% 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 20% less than the $1,000 stated principal amount of each Trigger PLUS, 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 Trigger PLUS, without any buffer. There is no minimum payment at maturity on the Trigger PLUS, and, accordingly, you could lose your entire initial investment in the Trigger PLUS.

￭The appreciation potential of the Trigger PLUS is limited by the maximum payment at maturity. The appreciation potential of the Trigger PLUS is limited by the maximum payment at maturity of $1,287 per Trigger PLUS, or 128.70% of the stated principal amount. Although the leverage factor provides 200% exposure to any increase in the final index value over the initial index value, because the payment at maturity will be limited to 128.70% of the stated principal amount for the Trigger PLUS, any increase in the final index value over the initial index value by more than 14.35% of the initial index value will not further increase the return on the Trigger PLUS.

￭The market price of the Trigger PLUS will be influenced by many unpredictable factors. Several factors, many of which are beyond our control, will influence the value of the Trigger PLUS in the secondary market and the price at which MS & Co. may be willing to purchase or sell the Trigger PLUS in the secondary market, including the value (including whether the value is below the trigger level), volatility (frequency and magnitude of changes in value) and dividend yield of the underlying index, interest and yield rates in the market, time remaining until the Trigger PLUS mature, geopolitical conditions and economic, financial, political, regulatory or judicial events that affect the underlying index or equities markets generally and which may affect the final index value of the underlying index, and any actual or anticipated changes in our credit ratings or credit spreads. The level of the underlying index may be, and has recently been, volatile, and we can give you no assurance that the volatility will lessen. See "Tokyo Stock Price Index Overview" below. You may receive less, and possibly significantly less, than the stated principal amount per Trigger PLUS if you try to sell your Trigger PLUS prior to maturity.

￭The Trigger PLUS 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 Trigger PLUS. You are dependent on our ability to pay all amounts due on the Trigger PLUS at maturity and therefore you are subject to our credit risk. If we default on our obligations under the Trigger PLUS, your investment would be at risk and you could lose some or all of your investment. As a result, the market value of the Trigger PLUS 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 Trigger PLUS.

￭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 Trigger PLUS is not linked to the value of the underlying index at any time other than the valuation date. The final index value will be based on 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, the payment at maturity may be less, and may 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 actual value of the underlying index on the stated maturity date or at other times during the term of the Trigger PLUS 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 Trigger PLUS is not equivalent to investing in the underlying index. Investing in the Trigger PLUS is not equivalent to investing in the underlying index or its component stocks. Investors in the Trigger PLUS 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 Trigger PLUS in the original issue price reduce the economic terms of the Trigger PLUS, cause the estimated value of the Trigger PLUS 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 Trigger PLUS 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 Trigger PLUS in the original issue price and the lower rate we are willing to pay as issuer make the economic terms of the Trigger PLUS less favorable to you than they otherwise would be.

However, because the costs associated with issuing, selling, structuring and hedging the Trigger PLUS 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 Trigger PLUS 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 Trigger PLUS 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 Trigger PLUS than those generated by others, including other dealers in the market, if they attempted to value the Trigger PLUS. 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 Trigger PLUS in the secondary market (if any exists) at any time. The value of your Trigger PLUS 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 Trigger PLUS will be influenced by many unpredictable factors" above.

￭The Trigger PLUS will not be listed on any securities exchange and secondary trading may be limited. The Trigger PLUS will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the Trigger PLUS. MS & Co. may, but is not obligated to, make a market in the Trigger PLUS 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 Trigger PLUS, 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 Trigger PLUS. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Trigger PLUS easily. Since other broker-dealers may not participate significantly in the

December 2024 Page 7

Morgan Stanley Finance LLC

Dual Directional Trigger PLUS Based on the Performance of the Tokyo Stock Price Index due December 17, 2026

Trigger Performance Leveraged Upside SecuritiesSM

Principal at Risk Securities

secondary market for the Trigger PLUS, the price at which you may be able to trade your Trigger PLUS 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 Trigger PLUS, it is likely that there would be no secondary market for the Trigger PLUS. Accordingly, you should be willing to hold your Trigger PLUS to maturity.

￭The calculation agent, which is a subsidiary of Morgan Stanley and an affiliate of MSFL, will make determinations with respect to the Trigger PLUS. 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 PLUS-Postponement of Valuation Date(s)," "-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 Trigger PLUS on the pricing date.

￭Hedging and trading activity by our affiliates could potentially adversely affect the value of the Trigger PLUS. One or more of our affiliates and/or third-party dealers expect to carry out hedging activities related to the Trigger PLUS (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 Trigger PLUS, 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, could increase the trigger level, which is 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 Trigger PLUS. Additionally, such hedging or trading activities during the term of the Trigger PLUS, 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 Trigger PLUS 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 PLUS (together, the "Tax Disclosure Sections") concerning the U.S. federal income tax consequences of an investment in the Trigger PLUS. There is no direct legal authority regarding the proper U.S. federal tax treatment of the Trigger PLUS, 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 Trigger PLUS are uncertain, and the IRS or a court might not agree with the tax treatment of a Trigger PLUS 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 Trigger PLUS, the tax consequences of the ownership and disposition of the Trigger PLUS, 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 Trigger PLUS, 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 Trigger PLUS, 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 Trigger PLUS 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.

￭Governmental regulatory actions, such as sanctions, could adversely affect your investment in the Trigger PLUS. Governmental regulatory actions, including, without limitation, sanctions-related actions by the U.S. or a foreign government, could prohibit or otherwise restrict persons from holding the Trigger PLUS or the component securities of the underlying index, or engaging in transactions in them, and any such action could adversely affect the value of the underlying index or the Trigger PLUS. These regulatory actions could result in restrictions on the Trigger PLUS and could result in the loss of a significant portion or all of your initial investment in the Trigger PLUS, including if you are forced to divest the Trigger PLUS due to the government mandates, especially if such divestment must be made at a time when the value of the Trigger PLUS has declined.

￭Adjustments to the underlying index could adversely affect the value of the Trigger PLUS. 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.

￭Past performance is not indicative of future performance. The actual performance of the underlying index over the term of the Trigger PLUS, as well as the amount payable at maturity, may bear little relation to the historical closing values or to the hypothetical payoff examples set forth herein. We cannot predict the future performance of the underlying index.

You should also note that JPX Market Innovation & Research, Inc. ("JPXI") recently implemented methodology changes to the TOPIX® Index that are being carried out in stages through January 2025. Among other things, this means that, with respect to the TOPIX® Index, limited historical underlying index performance information is available incorporating the changes that have been carried out to date. Specifically, prior to April 4, 2022, the component stocks of the TOPIX® Index consisted of all domestic common stocks listed on the First Section of the Tokyo Stock Exchange (the "TSE"). On April 4, 2022, JPXI began revisions to the TOPIX® Index in conjunction with the restructuring of the TSE into three new market segments: the Prime Market, the Standard Market and the Growth Market. Stocks that were components of the TOPIX® Index as of April 1, 2022 continue to be included after the market restructuring, regardless of their new market segment. However, component stocks with tradeable share market capitalization of under JPY 10 billion are designated as "phased weighting reduction constituents," and their weighting will be gradually reduced in ten stages on the last business day of each quarter beginning in October 2022 and ending in January 2025. Subject to a re-evaluation after the fourth stage, they will be removed from the TOPIX® Index on the last business day of January 2025. Because revisions to the composition of the TOPIX® Index are being carried out in several stages over a period of approximately 2.25 years, historical performance of the underlying index that reflects all of the currently contemplated changes will not be available until the final stage of revisions is implemented in January 2025. You may receive less, and possibly significantly less, than the stated principal amount per Trigger PLUS if you are able to sell your Trigger PLUS prior to maturity.

Tokyo Stock Price Index Overview

The Tokyo Stock Price Index, which we also refer to as the TOPIX® Index, is published by JPXI. The TOPIX® Index was developed by the TSE. Publication of the TOPIX® Index began on July 1, 1969, based on a base index value of 100 as of January 4, 1968. Prior to April 4, 2022, the TSE domestic stock market was divided into two sections: the First Section and the Second Section. Listings of stocks on the TSE were divided between these two sections, with stocks listed on the First Section typically being limited to larger, longer-established and more actively traded issues and the Second Section to smaller and newly listed companies. At that time, the component stocks of the TOPIX® Index consisted of all domestic common stocks listed on the First Section of the TSE. On April 4, 2022, JPXI began revisions to the TOPIX® Index in conjunction with the restructuring of the TSE into three new market segments: the Prime Market, the Standard Market and the Growth Market. Stocks that were components of the TOPIX® Index as of April 1, 2022 continue to be included after the market restructuring, regardless of their new market segment. However, component stocks with tradeable share market capitalization of under JPY 10 billion are designated as "phased weighting reduction constituents," and their weighting will be gradually reduced in ten stages on the last business day of each quarter beginning in October 2022 and ending in January 2025. Subject to a re-evaluation after the fourth stage, they will be removed from the TOPIX® Index on the last business day of January 2025. The TOPIX® Index is computed and published every second via the Market Information System, and is reported to securities companies, news media, and other institutions across Japan. For additional information about the TOPIX® Index, see the information set forth under "Tokyo Stock Price Index" in the accompanying index supplement.

Additional Information About the Trigger PLUS

Additional Information:
Minimum ticketing size:	$1,000 / 1 Trigger PLUS
Tax considerations:	Although there is uncertainty regarding the U.S. federal income tax consequences of an investment in the Trigger PLUS 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 Trigger PLUS as a single financial contract that is an "open transaction" for U.S. federal income tax purposes. Assuming this treatment of the Trigger PLUS is respected and subject to the discussion in "United States Federal Taxation" in the accompanying product supplement for PLUS, 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 Trigger PLUS prior to settlement, other than pursuant to a sale or exchange. ￭Upon sale, exchange or settlement of the Trigger PLUS, 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 Trigger PLUS. Such gain or loss should be long-term capital gain or loss if the investor has held the Trigger PLUS 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 Trigger PLUS. An alternative characterization of the Trigger PLUS could materially and adversely affect the tax consequences of ownership and disposition of the Trigger PLUS, 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 Trigger PLUS, possibly with retroactive effect. As discussed in the accompanying product supplement for PLUS, 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 Trigger PLUS do not have a delta of one with respect to any Underlying Security, our counsel is of the opinion that the Trigger PLUS 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 Trigger PLUS. Both U.S. and non-U.S. investors considering an investment in the Trigger PLUS should read the discussion under "Risk Factors" in this document and the discussion under "United States Federal Taxation" in the accompanying product supplement for PLUS and consult their tax advisers regarding all aspects of the U.S. federal income tax consequences of an investment in the Trigger PLUS, 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 PLUS, 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 Trigger PLUS.

Use of proceeds and hedging:	The proceeds from the sale of the Trigger PLUS will be used by us for general corporate purposes. We will receive, in aggregate, $1,000 per Trigger PLUS issued, because, when we enter into hedging transactions in order to meet our obligations under the Trigger PLUS, our hedging counterparty will reimburse the cost of the agent's commissions. The costs of the Trigger PLUS borne by you and described on page 2 above comprise the agent's commissions and the cost of issuing, structuring and hedging the Trigger PLUS. On or prior to the pricing date, we will hedge our anticipated exposure in connection with the Trigger PLUS by entering into hedging transactions with our affiliates and/or third party dealers. We expect our hedging counterparties to take positions in stocks of the underlying index, in futures and/or options contracts on the underlying index or any component stocks of the underlying index listed on major securities markets, or in any other 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 trigger level, which is 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 Trigger PLUS. In addition, through our affiliates, we are likely to modify our hedge position throughout the term of the Trigger PLUS, 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 Trigger PLUS, 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 Trigger PLUS 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 for PLUS.
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 Trigger PLUS, either directly or indirectly.
Supplemental information regarding plan of distribution; conflicts of interest:	The agent may distribute the Trigger PLUS through Morgan Stanley Smith Barney LLC ("Morgan Stanley Wealth Management"), as selected dealer, or other dealers, which may include Morgan Stanley & Co. International plc ("MSIP") and Bank Morgan Stanley AG. Morgan Stanley Wealth Management, MSIP and Bank Morgan Stanley AG are affiliates of ours. Selected dealers, including Morgan Stanley Wealth Management, and their financial advisors will collectively receive from the agent, Morgan Stanley & Co. LLC, a fixed sales commission of $20 for each Trigger PLUS they sell. In addition, Morgan Stanley Wealth Management will receive a structuring fee of $5 for each Trigger PLUS. The costs included in the original issue price of the Trigger PLUS will include a fee paid by MS & Co. to LFT Securities, LLC, an entity in which an affiliate of Morgan Stanley Wealth Management has an ownership interest, for providing certain electronic platform services with respect to this offering. 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 Trigger PLUS. 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 for PLUS.
Validity of the Trigger PLUS:	In the opinion of Davis Polk & Wardwell LLP, as special counsel to MSFL and Morgan Stanley, when the Trigger PLUS 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 Trigger PLUS 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,
