Buffered Performance Leveraged Upside Securities℠

Fully and Unconditionally Guaranteed by Morgan Stanley

Principal at Risk Securities

The Buffered PLUS are unsecured obligations of Morgan Stanley Finance LLC ("MSFL") and are fully and unconditionally guaranteed by Morgan Stanley. The Buffered PLUS will pay no interest, provide a minimum payment at maturity of only 20% of the stated principal amount 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 underlying shares have appreciated in value, investors will receive the stated principal amount of their investment plus leveraged upside performance of the underlying shares, subject to the maximum payment at maturity. If the underlying shares have depreciated in value, but the underlying shares have not declined by more than the specified buffer amount, the Buffered PLUS will redeem for par. However, if the underlying shares have declined by more than the buffer amount, investors will lose 1% for every 1% decline beyond the specified buffer amount, subject to the minimum payment at maturity of 20% of the stated principal amount. Investors may lose up to 80% of the stated principal amount of the Buffered PLUS. The Buffered PLUS are for investors who seek an equity fund-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 leverage and buffer features that in each case apply to a limited range of performance of the underlying shares. The Buffered PLUS 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 Buffered 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

Buffered Performance Leveraged Upside Securities

Principal at Risk Securities

The Buffered PLUS Based on the iShares® China Large-Cap ETF due May 5, 2026 (the "Buffered PLUS") can be used:

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

￭To enhance returns and potentially outperform the underlying shares in a moderately bullish scenario.

￭To achieve similar levels of upside exposure to the underlying shares as a direct investment, subject to the maximum payment at maturity, while using fewer dollars by taking advantage of the leverage factor.

￭To obtain a buffer against a specified level of negative performance in the underlying shares.

Maturity:	Approximately 1.5 years
Leverage factor:	125%
Maximum payment at maturity:	$1,265 per Buffered PLUS (126.50% of the stated principal amount)
Minimum payment at maturity:	$200 per Buffered PLUS (20% of the stated principal amount). Investors may lose up to 80% of the stated principal amount of the Buffered PLUS.
Buffer amount:	20%
Coupon:	None

The original issue price of each Buffered PLUS is $1,000. This price includes costs associated with issuing, selling, structuring and hedging the Buffered PLUS, which are borne by you, and, consequently, the estimated value of the Buffered PLUS on the pricing date is less than $1,000. We estimate that the value of each Buffered PLUS on the pricing date is $971.70.

What goes into the estimated value on the pricing date?

In valuing the Buffered PLUS on the pricing date, we take into account that the Buffered PLUS comprise both a debt component and a performance-based component linked to the underlying shares. The estimated value of the Buffered PLUS is determined using our own pricing and valuation models, market inputs and assumptions relating to the underlying shares, instruments based on the underlying shares, 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 Buffered PLUS?

In determining the economic terms of the Buffered PLUS, including the leverage factor, the maximum payment at maturity, the buffer amount and the minimum 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 Buffered 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 Buffered PLUS?

The price at which MS & Co. purchases the Buffered PLUS in the secondary market, absent changes in market conditions, including those related to the underlying shares, 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 Buffered 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 Buffered PLUS in the secondary market, absent changes in market conditions, including those related to the underlying shares, 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 Buffered PLUS, and, if it once chooses to make a market, may cease doing so at any time.

Key Investment Rationale

The Buffered PLUS offer leveraged upside exposure to the underlying shares, subject to the maximum payment at maturity, while providing limited protection against negative performance of the underlying shares. Once the underlying shares have decreased in price by more than a specified buffer amount, investors are exposed to the negative performance of the underlying shares, subject to the minimum payment at maturity. At maturity, if the underlying shares have appreciated, investors will receive the stated principal amount of their investment plus leveraged upside performance of the underlying shares, subject to the maximum payment at maturity. At maturity, if the underlying shares have depreciated and (i) if the closing price of the underlying shares has not declined from the initial share price by more than the specified buffer amount, the Buffered PLUS will redeem for par, or (ii) if the closing price of the underlying shares has declined by more than the buffer amount, the investor will lose 1% for every 1% decline beyond the specified buffer amount, subject to theminimum payment at maturity. Investors may lose up to 80% of the stated principal amount of the Buffered PLUS.

Leveraged Performance up to a Cap	The Buffered PLUS offer investors an opportunity to capture enhanced returns for a certain range of positive performance relative to a direct investment in the underlying shares, subject to the maximum payment at maturity.
Upside Scenario	The underlying shares increase in price, and, at maturity, the Buffered PLUS redeem for the stated principal amount of $1,000 plus 125% of the share return, subject to the maximum payment at maturity of $1,265 per Buffered PLUS (126.50% of the stated principal amount).
Par Scenario	The underlying shares decline in price by no more than 20%, and, at maturity, the Buffered PLUS redeem for the stated principal amount of $1,000.
Downside Scenario	The underlying shares decline in price by more than 20%, and, at maturity, the Buffered PLUS redeem for less than the stated principal amount by an amount that is proportionate to the percentage decrease of the underlying shares from the initial share price, plus the buffer amount of 20%. (Example: if the underlying shares decrease in price by 65%, investors would lose 45% of their principal and the Buffered PLUS will redeem for $550, or 55% of the stated principal amount.) The minimum payment at maturity is $200 per Buffered PLUS.

How it works

￭Upside Scenario. If the final share price is greater than the initial share price, investors will receive the $1,000 stated principal amount plus 125% of the appreciation of the underlying shares over the term of the Buffered PLUS, subject to the maximum payment at maturity. An investor will realize the maximum payment at maturity of $1,265 per Buffered PLUS (126.50% of the stated principal amount) at a final share price of 121.20% of the initial share price.

￭If the value of the underlying shares appreciates 2%, the investor would receive a 2.50% return, or $1,025 per Buffered PLUS.

￭If the value of the underlying shares appreciates 400%, the investor would receive only the maximum payment at maturity of $1,265 per Buffered PLUS, or 126.50% of the stated principal amount.

￭Par Scenario. If the final share price is less than or equal to the initial share price but has decreased from the initial share price by an amount less than or equal to the buffer amount of 20%, investors will receive the stated principal amount of $1,000 per Buffered PLUS.

￭Downside Scenario. If the final share price is less than the initial share price and has decreased from the initial share price by an amount greater than the buffer amount of 20%, investors will receive an amount that is less than the stated principal amount by an amount that is proportionate to the percentage decrease in the value of the underlying shares from the initial share price, plus the buffer amount of 20%. The minimum payment at maturity is $200 per Buffered PLUS.

￭For example, if the value of the underlying shares depreciates 70%, investors would lose 50% of their principal and receive only $500 per Buffered PLUS at maturity, or 50% of the stated principal amount.

Risk Factors

This section describes the material risks relating to the Buffered 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. You should also consult with your investment, legal, tax, accounting and other advisers in connection with your investment in the Buffered PLUS.

Risks Relating to an Investment in the Buffered PLUS

￭Buffered PLUS do not pay interest and provide a minimum payment at maturity of only 20% of your principal. The terms of the Buffered PLUS differ from those of ordinary debt securities in that the Buffered PLUS do not pay interest, and provide a minimum payment at maturity of only 20% of the stated principal amount of the Buffered PLUS, subject to our credit risk. If the final share price is less than 80% of the initial share price, you will receive for each Buffered PLUS that you hold a payment at maturity that is less than the stated principal amount of each Buffered PLUS by an amount proportionate to the decline in the closing value of the underlying shares from the initial share price, plus $200 per Buffered PLUS. Accordingly, investors may lose up to 80% of the stated principal amount of the Buffered PLUS.

￭The appreciation potential of the Buffered PLUS is limited by the maximum payment at maturity.The appreciation potential of the Buffered PLUS is limited by the maximum payment at maturity of $1,265 per Buffered PLUS, or 126.50% of the stated principal amount. Although the leverage factor provides 125% exposure to any increase in the final share price over the initial share price, because the payment at maturity will be limited to 126.50% of the stated principal amount for the Buffered PLUS, any increase in the final share price over the initial share price by more than 21.20% of the initial share price will not further increase the return on the Buffered PLUS.

￭The market price of the Buffered PLUS will be influenced by many unpredictable factors. Several factors, many of which are beyond our control, will influence the value of the Buffered PLUS in the secondary market and the price at which MS & Co. may be willing to purchase or sell the Buffered PLUS in the secondary market, including the trading price, volatility (frequency and magnitude of changes in value) and dividends of the underlying shares and of the stocks composing the FTSE China 50 Index (the "share underlying index"), interest and yield rates in the market, time remaining until the Buffered PLUS mature, geopolitical conditions and economic, financial, political, regulatory or judicial events that affect the underlying shares or equities markets generally and which may affect the final share price of the underlying shares, the occurrence of certain events affecting the underlying shares 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. Generally, the longer the time remaining to maturity, the more the market price of the Buffered PLUS will be affected by the other factors described above. The price of the underlying shares may be, and has recently been, volatile, and we can give you no assurance that the volatility will lessen. See "iShares® China Large-Cap ETF Overview" below. You may receive less, and possibly significantly less, than the stated principal amount per Buffered PLUS if you try to sell your Buffered PLUS prior to maturity.

￭The Buffered 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 Buffered PLUS. You are dependent on our ability to pay all amounts due on the Buffered PLUS at maturity and therefore you are subject to our credit risk. If we default on our obligations under the Buffered 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 Buffered 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 Buffered 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 Buffered PLUS is not linked to the value of the underlying shares at any time other than the valuation date. The final share price will be based on the closing price on the valuation date, subject to postponement for non-trading days and certain market disruption events. Even if the value of the underlying shares appreciates prior to the valuation date but then drops by the valuation date by more than 20%, the payment at maturity will 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 shares prior to such drop. Although the actual value of the underlying shares on the stated maturity date or at other times during the term of the Buffered PLUS may be

October 2024Page 6

Morgan Stanley Finance LLC

Buffered PLUS Based on the iShares® China Large-Cap ETF due May 5, 2026

Buffered Performance Leveraged Upside SecuritiesSM

Principal at Risk Securities

higher than the closing price on the valuation date, the payment at maturity will be based solely on the closing price on the valuation date.

￭Investing in the Buffered PLUS is not equivalent to investing in the underlying shares or the stocks composing the share underlying index. Investing in the Buffered PLUS is not equivalent to investing in the underlying shares, the share underlying Index or the stocks that constitute the share underlying index. Investors in the Buffered PLUS will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the underlying shares or the stocks that constitute the share 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 Buffered PLUS in the original issue price reduce the economic terms of the Buffered PLUS, cause the estimated value of the Buffered 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 Buffered 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 Buffered PLUS in the original issue price and the lower rate we are willing to pay as issuer make the economic terms of the Buffered PLUS less favorable to you than they otherwise would be.

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

￭The Buffered PLUS will not be listed on any securities exchange and secondary trading may be limited. The Buffered PLUS will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the Buffered PLUS. MS & Co. may, but is not obligated to, make a market in the Buffered 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 Buffered 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 Buffered PLUS. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Buffered PLUS easily. Since other broker-dealers may not participate significantly in the secondary market for the Buffered PLUS, the price at which you may be able to trade your Buffered 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 Buffered PLUS, it is likely that there would be no secondary market for the Buffered PLUS. Accordingly, you should be willing to hold your Buffered 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 Buffered PLUS. As calculation agent, MS & Co. will determine the initial share price and the final share price, and will calculate the amount of cash you receive at maturity. 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 share price in the event of a market disruption event or discontinuance of the share underlying index. These potentially subjective determinations may adversely affect the payout to you at maturity. For further information regarding these types of determinations, see

"Description of PLUS-Postponement of Valuation Date(s)" and "-Calculation Agent and Calculations" in the accompanying product supplement. In addition, MS & Co. has determined the estimated value of the Buffered PLUS on the pricing date.

￭Hedging and trading activity by our affiliates could potentially adversely affect the value of the Buffered PLUS. One or more of our affiliates and/or third-party dealers expect to carry out hedging activities related to the Buffered PLUS (and to other instruments linked to the underlying shares or the share underlying index), including trading in the underlying shares and in other instruments related to the underlying shares or the share underlying index. As a result, these entities may be unwinding or adjusting hedge positions during the term of the Buffered 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 underlying shares or the stocks that constitute the share underlying index and other financial instruments related to the underlying shares or the share 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 share price, and, therefore, could increase the price at or above which the shares of the Fund must close on the valuation date so that investors do not suffer a loss on their initial investment in the Buffered PLUS. Additionally, such hedging or trading activities during the term of the Buffered PLUS, including on the valuation date, could adversely affect the closing price of the shares of the Fund on the valuation date, and, accordingly, the amount of cash an investor will receive at maturity.

￭The U.S. federal income tax consequences of an investment in the Buffered 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 Buffered PLUS. As discussed in the Tax Disclosure Sections, there is a risk that the "constructive ownership" rule could apply, in which case all or a portion of any long-term capital gain recognized by a U.S. Holder could be recharacterized as ordinary income and an interest charge could be imposed. In addition, there is no direct legal authority regarding the proper U.S. federal tax treatment of the Buffered 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 Buffered PLUS are uncertain, and the IRS or a court might not agree with the tax treatment of a Buffered 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 Buffered PLUS, the tax consequences of the ownership and disposition of the Buffered 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 Buffered 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 Buffered 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 Shares

￭There are risks associated with investments in securities, such as the Buffered PLUS, linked to the value of foreign (and especially emerging markets) equity securities. The underlying shares track the performance of the share underlying index, which is linked to the value of foreign (and especially emerging markets) 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 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. In addition, the stocks that are generally tracked by the underlying shares have been issued by companies in various emerging markets countries, which pose further risks in addition to the risks associated with investing in foreign equity markets generally. Countries with emerging markets may have relatively unstable governments, may present the risks of nationalization of businesses, restrictions on foreign ownership and prohibitions on the repatriation of assets, and may have less protection of property rights than more developed countries. The economies of countries with emerging markets may be based on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates. 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 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.

Principal at Risk Securities

￭The price of the underlying shares is subject to currency exchange risk. Because the price of the underlying shares is linked to the value of foreign equity securities, holders of the Buffered PLUS will be exposed to currency exchange rate risk with respect to each of the currencies in which such component securities trade. Exchange rate movements for a particular currency are volatile and are the result of numerous factors including the supply of, and the demand for, those currencies, as well as relevant government policy, intervention or actions, but are also influenced significantly from time to time by political or economic developments, and by macroeconomic factors and speculative actions related to the relevant region. An investor's net exposure will depend on the extent to which the currencies of the component securities strengthen or weaken against the U.S. dollar and the relative weight of each currency. If, taking into account such weighting, the dollar strengthens against the currencies of the component securities represented in the share underlying index, the price of the underlying shares will be adversely affected and the payment at maturity on the Buffered PLUS may be reduced.

Of particular importance to potential currency exchange risk are:

oexisting and expected rates of inflation;

oexisting and expected interest rate levels;

othe balance of payments; and

othe extent of governmental surpluses or deficits in the countries represented in the share underlying index and the United States.

All of these factors are in turn sensitive to the monetary, fiscal and trade policies pursued by the governments of the various countries represented in the share underlying index and the United States and other countries important to international trade and finance.

￭Recent executive orders could adversely affect your investment in the Buffered PLUS. Pursuant to recent executive orders issued by the U.S. Government, U.S. persons are prohibited from engaging in transactions in, or possession of, publicly traded securities of certain companies that are determined to be linked to the People's Republic of China military, intelligence and security apparatus, or securities that are derivative of, or are designed to provide investment exposure to, those securities, such as structured products.

If the issuer of any of the component stocks of the share underlying indexequity securities held by the underlying shares is in the future designated as such a prohibited company, the value of that company may be adversely affected, potentially significantly, which would adversely affect the performance of the underlying shares. In addition, under these circumstances, the publisher may remove the equity securities of that company from the share underlying index. Any changes to the composition of the share underlying indexin response to these executive orders could adversely affect the performance of the underlying shares. Any such action could result in the loss of a significant portion or all of your initial investment in the Buffered PLUS. Moreover, if the publisher does not remove the prohibited company, that could mean that transactions in, or holdings of, the Buffered PLUS may be prohibited under U.S. law. Accordingly, you may be forced to sell the Buffered PLUS in order to comply with U.S. law, and you may be forced to realize a loss on your investment, and would lose the opportunity cost of continued investment in the Buffered PLUS, upon such forced divestment.

￭Adjustments to the underlying shares or to the share underlying index could adversely affect the value of the Buffered PLUS. The investment adviser to the Fund, BlackRock Fund Advisors (the "Investment Adviser"), seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the share underlying index. Pursuant to its investment strategy or otherwise, the Investment Advisor may add, delete or substitute the stocks composing the Fund. Any of these actions could adversely affect the price of the underlying shares and, consequently, the value of the Buffered PLUS. The publisher of the share underlying index is responsible for calculating and maintaining the share underlying index. The publisher of the share underlying index may add, delete or substitute the stocks constituting the share underlying index or make other methodological changes that could change the value of the share underlying index, and, consequently, the price of the underlying shares and the value of the Buffered PLUS. The publisher of the share underlying index may discontinue or suspend calculation or publication of the share underlying index at any time. If trading in the underlying shares is permanently discontinued and/or the Fund is liquidated or otherwise terminated, and the publisher of the share underlying index subsequently discontinues publication of the share underlying index, the calculation agent will have the sole discretion to substitute a successor index that is comparable to the discontinued share underlying index and is permitted to consider indices that are calculated and published by the calculation agent or any of its affiliates. Any of these actions could adversely affect the price of the underlying shares, and, consequently, the value of the Buffered PLUS.

￭The performance and market price of the Fund, particularly during periods of market volatility, may not correlate with the performance of the share underlying index, the performance of the component securities of the share underlying index or the net asset value per share of the Fund. The Fund does not fully replicate the share underlying index and may hold securities that are different than those included in the share underlying index. In addition, the performance of the Fund will reflect additional

Buffered PLUS Based on the iShares® China Large-Cap ETF due May 5, 2026

Buffered Performance Leveraged Upside SecuritiesSM

Principal at Risk Securities

transaction costs and fees that are not included in the calculation of the share underlying index. All of these factors may lead to a lack of correlation between the performance of the Fund and the share underlying index. In addition, corporate actions (such as mergers and spin-offs) with respect to the equity securities underlying the Fund may impact the variance between the performances of the Fund and the share underlying index. Finally, because the shares of the Fund are traded on an exchange and are subject to market supply and investor demand, the market price of one share of the Fund may differ from the net asset value per share of the Fund.

In particular, during periods of market volatility, or unusual trading activity, trading in the securities underlying the Fund may be disrupted or limited, or such securities may be unavailable in the secondary market. Under these circumstances, the liquidity of the Fund may be adversely affected, market participants may be unable to calculate accurately the net asset value per share of the Fund, and their ability to create and redeem shares of the Fund may be disrupted. Under these circumstances, the market price of shares of the Fund may vary substantially from the net asset value per share of the Fund or the level of the share underlying index.

For all of the foregoing reasons, the performance of the Fund may not correlate with the performance of the share underlying index, the performance of the component securities of the share underlying index or the net asset value per share of the Fund. Any of these events could materially and adversely affect the price of the shares of the Fund and, therefore, the value of the Buffered PLUS. Additionally, if market volatility or these events were to occur on the valuation date, the calculation agent would maintain discretion to determine whether such market volatility or events have caused a market disruption event to occur, and such determination would affect the payment at maturity of the Buffered PLUS. If the calculation agent determines that no market disruption event has taken place, the payment at maturity would be based solely on the published closing price per share of the Fund on the valuation date, even if the Fund's shares are underperforming the share underlying index or the component securities of the share underlying index and/or trading below the net asset value per share of the Fund.

￭The antidilution adjustments the calculation agent is required to make do not cover every event that could affect the underlying shares. MS & Co., as calculation agent, will adjust the amount payable at maturity for certain events affecting the underlying shares. However, the calculation agent will not make an adjustment for every event that could affect the underlying shares. If an event occurs that does not require the calculation agent to adjust the adjustment factor, the market price of the Buffered PLUS may be materially and adversely affected.

Additional Information About the Buffered PLUS

Additional Information:
Minimum ticketing size:	$1,000 / 1 Buffered PLUS
Tax considerations:	Although there is uncertainty regarding the U.S. federal income tax consequences of an investment in the Buffered 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 Buffered PLUSas a single financial contract that is an "open transaction" for U.S. federal income tax purposes. Assuming this treatment of the Buffered 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 Buffered PLUS prior to settlement, other than pursuant to a sale or exchange. ￭Upon sale, exchange or settlement of the Buffered 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 Buffered PLUS. Subject to the discussion below concerning the potential application of the "constructive ownership" rule, such gain or loss should be long-term capital gain or loss if the investor has held the Buffered PLUS for more than one year, and short-term capital gain or loss otherwise. Because the Buffered PLUS are linked to shares of an exchange-traded fund, although the matter is not clear, there is a risk that an investment in the Buffered PLUS will be treated as a "constructive ownership transaction" under Section 1260 of the Internal Revenue Code of 1986, as amended (the "Code"). If this treatment applies, all or a portion of any long-term capital gain of the U.S. Holder in respect of the Buffered PLUS could be recharacterized as ordinary income (in which case an interest charge will be imposed). As a result of certain features of the Buffered PLUS, including the leveraged upside payment, it is unclear how to calculate the amount of gain that would be recharacterized if an investment in the Buffered PLUS were treated as a constructive ownership transaction. Due to the lack of governing authority, our counsel is unable to opine as to whether or how Section 1260 of the Code applies to the Buffered PLUS. U.S. investors should read the section entitled "United States Federal Taxation-Tax Consequences to U.S. Holders-Possible Application of Section 1260 of the Code" in the accompanying product supplement for PLUS for additional information and consult their tax advisers regarding the potential application of the "constructive ownership" rule. We do not plan to request a ruling from the Internal Revenue Service (the "IRS") regarding the treatment of the Buffered PLUS. An alternative characterization of the Buffered PLUS could materially and adversely affect the tax consequences of ownership and disposition of the Buffered 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 Buffered PLUS, possibly with retroactive effect. As discussed in the accompanying product supplement for PLUS, Section 871(m) of the Code 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 Buffered PLUS do not have a delta of one with respect to any Underlying Security, our counsel is of the opinion that the Buffered 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 Buffered PLUS. Both U.S. and non-U.S. investors considering an investment in the Buffered 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 Buffered PLUS, including possible alternative treatments, the potential application of the constructive ownership rule, 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 Buffered PLUS.
Use of proceeds and hedging:	The proceeds from the sale of the Buffered PLUS will be used by us for general corporate purposes. We will receive, in aggregate, $1,000 per Buffered PLUS issued, because, when we enter into hedging transactions in order to meet our obligations under the Buffered PLUS, our hedging counterparty will reimburse the cost of the agent's commissions. The costs of the Buffered PLUS borne by you and described on page 2 above comprise the agent's commissions and the cost of issuing, structuring and hedging the Buffered PLUS. On or prior to the pricing date, we will hedge our anticipated exposure in connection with the Buffered PLUS, by entering into hedging transactions with our affiliates and/or third-party dealers. We expect our hedging counterparties to take positions in underlying shares, futures and options contracts on the underlying shares, and any component stocks of the share underlying index 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 price of the underlying shares on the pricing date, and, therefore, could increase the price at or above which the underlying shares must close on the valuation date so that investors do not suffer a loss on their initial investment in the Buffered PLUS. In addition, through our affiliates, we are likely to modify our hedge position throughout the term of the Buffered PLUS, including on the valuation date, by purchasing and selling the underlying shares, futures or options contracts on the underlying shares or component stocks of the share underlying index 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 Buffered 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 shares, and, therefore, adversely affect the value of the Buffered PLUS or the payment you will receive at maturity. 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 Buffered PLUS, either directly or indirectly.
Supplemental information regarding plan of distribution; conflicts of interest:	MS & Co. expects to sell all of the Buffered PLUS that it purchases from us to an unaffiliated dealer at a price of $997.50 per Buffered PLUS, for further sale to certain fee-based advisory accounts at the price to public of $1,000 per Buffered PLUS. MS & Co. will not receive a sales commission with respect to the Buffered PLUS. 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 Buffered 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 Buffered PLUS:	In the opinion of Davis Polk & Wardwell LLP, as special counsel to MSFL and Morgan Stanley, when the Buffered 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

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 Buffered PLUS 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.
