Dual Directional Buffered PLUS Based on the Performance of the S&P 500® Futures Excess Return Index due August 27, 2029

Buffered Performance Leveraged Upside SecuritiesSM

Fully and Unconditionally Guaranteed by Morgan Stanley

Principal at Risk Securities

The Dual Directional Buffered PLUS, or “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 index has appreciated in value, investors will receive the stated principal amount of their investment plus leveraged upside performance of the underlying index. If the underlying index has depreciated in value, but the underlying index has not declined by more than the specified buffer amount, investors will receive the stated principal amount of their investment, plus an unleveraged positive return based on the absolute value of the performance of the underlying index, which will effectively be limited to a maximum return of 20%. However, if the underlying index has declined by more than the buffer amount, the absolute return feature will no longer be available and 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. These long-dated Buffered PLUS are for investors who seek an equity index-based return and who are willing to risk their principal and forgo current income in exchange for the leverage, buffer and absolute return features that in each case apply to a limited range of performance of the underlying index. The Buffered PLUS are notes issued as part of MSFL’s Series A Global Medium-Term Notes program.

The Buffered PLUS differ from the PLUS described in the accompanying product supplement for PLUS in that the Buffered PLUS offer the potential for a positive return at maturity if the underlying index depreciates by no more than 20%.

The underlying index measures the performance of the nearest maturing quarterly E-mini S&P 500 futures contract (the “futures contract”) trading on the Chicago Mercantile Exchange (the “CME”). The futures contract references the S&P 500® Index (the “reference index”). For more information about the S&P 500® Index, see the accompanying index supplement. For more information about the underlying index, see “Annex A — S&P 500® Futures Excess Return Index” beginning on page 15.

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

Dual Directional Buffered Performance Leveraged Upside Securities

Principal at Risk Securities

The Dual Directional Buffered PLUS Based on the Performance of the S&P 500® Futures Excess Return Index due August 27, 2029 (the "Buffered PLUS") can be used:

￭As an alternative to direct exposure to the underlying index that enhances returns for any positive performance of the underlying index

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

￭To achieve similar levels of upside exposure to the underlying index as a direct investment while using fewer dollars by taking advantage of the leverage factor

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

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

Maturity:	5 years
Leverage factor:	At least 181%. The actual leverage factor will be determined on the pricing date.
Buffer amount:	20%, with 1-to-1 downside exposure below the buffer
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.
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 will be less than $1,000. We estimate that the value of each Buffered PLUS on the pricing date will be approximately $972.40, or within $55.00 of that estimate. Our estimate of the value of the Buffered PLUS as determined on the pricing date will be set forth in the final pricing supplement.

What goes into the estimated value on the pricing date?

In valuing the 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 index. The estimated value of the Buffered 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 Buffered PLUS?

In determining the economic terms of the Buffered PLUS, including the leverage factor, 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 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 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 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 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 the potential for a positive return at maturity based on the absolute value of a limited range of percentage changes of the underlying index while providing limited protection against negative performance of the underlying index. Once the underlying index has decreased in value by more than the specified buffer amount, investors are exposed to the negative performance of the underlying index, subject to the minimum payment at maturity. At maturity, if the underlying index has appreciated, investors will receive the stated principal amount of their investment plus leveraged upside performance of the underlying index. At maturity, if the underlying index has depreciated and (i) if the final index value of the underlying index has not declined from the initial index value by more than the specified buffer amount, investors will receive the stated principal amount of their investment plus an unleveraged positive return based on the absolute value of the performance of the underlying index, which will effectively be limited to a maximum return of 20%, or (ii) if the final index value of the underlying index has declined by more than the buffer amount, the absolute return feature will no longer be available and investors will lose 1% for every 1% decline beyond the specified buffer amount, subject to the minimum payment at maturity. Investors may lose up to 80% of the stated principal amount of the Buffered PLUS.

Leveraged Upside Performance	The Buffered PLUS offer investors an opportunity to capture enhanced returns for any positive performance relative to a direct investment in the underlying index.
Absolute Return Feature	The Buffered 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 80% of the initial index value.
Upside Scenario if the Underlying Index Appreciates	The underlying index increases in value, and, at maturity, the Buffered PLUS redeem for the stated principal amount of $1,000 plus at least 181% of the index percent increase. The actual leverage factor will be determined on the pricing date.
Absolute Return Scenario	The underlying index declines in value by no more than 20%, and, at maturity, you receive a 1% positive return on the Buffered 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 Buffered 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 underlying index declines in value 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 index from the initial index value, plus the buffer amount of 20%. (Example: if the underlying index decreases in value by 35%, the Buffered PLUS will redeem for $850, or 85% of the stated principal amount.) The minimum payment at maturity is $200 per Buffered PLUS.

How the Buffered PLUS Work

Payoff Diagram

The payoff diagram below illustrates the payment at maturity on the Buffered PLUS based on the following terms:

Stated principal amount:	$1,000 per Buffered PLUS
Hypothetical leverage factor:	181%. The actual leverage factor will be determined on the pricing date.
Buffer amount:	20%
Minimum payment at maturity:	$200 per Buffered PLUS
Buffered PLUS Payoff Diagram

How it works

￭Upside Scenario.If the final index value is greater than the initial index value, investors will receive the $1,000 stated principal amount plus 181% of the appreciation of the underlying index over the term of the Buffered PLUS (assuming a leverage factor of 181%). The actual leverage factor will be determined on the pricing date.

￭Given the leverage factor of 181%, if the underlying index appreciates 2%, the investor would receive a 3.62% return, or $1,036.20 per Buffered PLUS.

￭Absolute Return Scenario.If the final index value is less than or equal to the initial index value but has decreased from the initial index value by an amount less than or equal to the buffer amount of 20%, the investor would receive a 1% positive return on the Buffered PLUS for each 1% negative return on the underlying index.

￭If the underlying index depreciates 5%, the investor would receive a 5% return, or $1,050 per Buffered 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 initial index value and has decreased from the initial index value 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 of the value of the underlying index from the initial index value, plus the buffer amount of 20%. The minimum payment at maturity is $200 per Buffered PLUS.

￭For example, if the underlying index depreciates 45%, investors would lose 25% of their principal and receive only $750 per Buffered PLUS at maturity, or 75% 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. We also urge you to consult 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

￭The 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 index value is less than 80% of the initial index value, the absolute return feature will no longer be available and you will instead 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 index from the initial index value, plus $200 per Buffered PLUS. Accordingly, investors may lose up to 80% of the stated principal amount of 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 value of the underlying index at any time, the volatility (frequency and magnitude of changes in value) of the underlying index, dividend rate on the stocks underlying the reference index, interest and yield rates in the market, the time remaining until the Buffered PLUS mature, geopolitical conditions and economic, financial, political, regulatory or judicial events that affect the futures contracts, the reference 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. 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 value of the underlying index may be, and has recently been, volatile, and we can give you no assurance that the volatility will lessen. See “S&P 500® Futures Excess Return Index 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 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 by more than 20% of the initial index value, 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 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 Buffered PLUS may be higher than the index closing value on the valuation date, the payment at maturity will be based solely on the index closing value on the valuation date.

￭Investing in the Buffered PLUS is not equivalent to investing in the underlying index. Investing in the Buffered PLUS is not equivalent to investing in the underlying index, the futures contract or the component stocks of the reference 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 component stocks of the reference index. Further, by purchasing the Buffered PLUS, you are taking credit risk to us and not to any counter-party to the futures contract linked to the underlying index. Your return on the Buffered PLUSwill not reflect the return you would realize if you purchased any stocks or futures contracts that are tracked directly or indirectly by 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 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 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 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 index value and the final index value, 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 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. For further information regarding these types of determinations, see “Description of PLUS—Postponement of Valuation Date(s),” “—Discontinuance of Any Underlying Index or Basket Index; Alteration of Method of Calculation,” “—Alternate Exchange Calculation in case of an Event of Default and “—Calculation Agent and Calculations” in the accompanying product supplement. In addition, MS & Co. has determined the estimated value of the 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 index, the futures contract, or the component stocks of the reference index), including trading in the futures contract and the stocks that constitute the reference 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 stocks that constitute the reference 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 value at or above which the underlying index 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 value of the underlying index 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. 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 Index

￭Higher future prices of the futures contract to which the underlying index is linked relative to its current prices may adversely affect the value of the underlying index and the value of the Buffered PLUS. The underlying index is linked to the E-mini S&P 500 futures contract currently listed for trading on the CME. As the relevant futures contract approaches expiration, it is replaced by a contract that has a later expiration. Thus, for example, a contract purchased and held in September may specify a December expiration. As time passes, the contract expiring in December is replaced by a contract for delivery in March. This process is referred to as “rolling.” If the market for these contracts is (putting aside other considerations) in “backwardation,” where the prices are lower in the distant delivery months than in the nearer delivery months, the sale of the December contract would take place at a price that is higher than the price of the March contract, thereby creating a “roll yield.” While many futures contracts have historically exhibited consistent periods of backwardation, backwardation will most likely not exist at all times. It is also possible for the market for these contracts to be in “contango.” Contango markets are those in which the prices of contracts are higher in the distant delivery months than in the nearer delivery months. The presence of contango and absence of backwardation in the market for these contracts could result in negative “roll yields,” which could adversely affect the value of the underlying index, and, accordingly, the value of the Buffered PLUS.

￭Suspensions or disruptions of market trading in futures markets could adversely affect the price of the Buffered PLUS. Securities markets and futures markets are subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets, the participation of speculators and government regulation and intervention. In addition, U.S. futures exchanges and some foreign exchanges have regulations that limit the amount of fluctuation in futures contract prices which may occur during a single business day. These limits are generally referred to as “daily price fluctuation limits” and the maximum or minimum price of a contract on any given day as a result of these limits is referred to as a “limit price.” Once the limit price has been reached in a particular contract, no trades may be made at a different price. Limit prices have the

effect of precluding trading in a particular contract or forcing the liquidation of contracts at disadvantageous times or prices. These circumstances could adversely affect the value of the underlying index, and, therefore, the value of the Buffered PLUS.

￭Legal and regulatory changes could adversely affect the return on and value of your Buffered PLUS. Futures contracts and options on futures contracts, including those related to the underlying index, are subject to extensive statutes, regulations, and margin requirements. The Commodity Futures Trading Commission, commonly referred to as the “CFTC,” and the exchanges on which such futures contracts trade, are authorized to take extraordinary actions in the event of a market emergency, including, for example, the retroactive implementation of speculative position limits or higher margin requirements, the establishment of daily limits and the suspension of trading. Furthermore, certain exchanges have regulations that limit the amount of fluctuations in futures contract prices that may occur during a single five-minute trading period. These limits could adversely affect the market prices of relevant futures and options contracts and forward contracts.

￭Adjustments to the underlying index could adversely affect the value of the Buffered PLUS. The underlying index publisher can make 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 is not precluded from considering indices that are calculated and published by the calculation agent or any of its affiliates. If the calculation agent determines that there is no appropriate successor index, the payment at maturity on the Buffered PLUS will be an amount based on the closing prices at maturity of the securities composing the underlying index at the time of such discontinuance, without rebalancing or substitution, computed by the calculation agent in accordance with the formula for calculating the underlying index last in effect prior to discontinuance of the underlying index.

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 PLUS as a single financial contract that is an “open transaction” for U.S. federal income tax purposes. However, because our counsel’s opinion is based in part on market conditions as of the date of this document, it is subject to confirmation on the pricing date. 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. 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. 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 Internal Revenue Code of 1986, as amended, and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% (or a lower applicable treaty rate) withholding tax on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities (each, an “Underlying Security”). Subject to certain exceptions, Section 871(m) generally applies to securities that substantially replicate the economic performance of one or more Underlying Securities, as determined based on tests set forth in the applicable Treasury regulations (a “Specified Security”). However, pursuant to an IRS notice, Section 871(m) will not apply to securities issued before January 1, 2027 that do not have a delta of one with respect to any Underlying Security. Based on the terms of the Buffered PLUS and current market conditions, we expect that the Buffered PLUS will not have a delta of one with respect to any Underlying Security on the pricing date. However, we will provide an updated determination in the final pricing supplement. Assuming that the 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, 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 beginning 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 the futures contract, in the stocks constituting the reference index, in futures and options contracts on the reference index and the stocks constituting the reference 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 value of the underlying index on the pricing date, and, therefore, could increase the value at or above which the underlying index must close on the valuation date so that investors do not suffer a 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 stocks constituting the reference index, in futures and options contracts on the reference index and the stocks constituting the reference 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 index, 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 $ per Buffered PLUS, for further sale to certain fee-based advisory accounts at the price to public of $1,000 per Buffered PLUS. In addition, selected dealers and their financial advisors may receive a structuring fee of up to $6.25 for each Buffered PLUS from the agent or its affiliates. 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. When MS & Co. prices this offering of Buffered PLUS, it will determine the economic terms of the Buffered PLUS, including the leverage factor, such that for each Buffered PLUS the estimated value on the pricing date will be no lower than the minimum level described in “Investment Summary” beginning on page 2. MS & Co. will conduct this offering in compliance with the requirements of FINRA Rule 5121 of the Financial Industry Regulatory Authority, Inc., which is commonly referred to as FINRA, regarding a FINRA member firm’s distribution of the securities of an affiliate and related conflicts of interest. MS & Co. or any of our other affiliates may not make sales in this offering to any discretionary account. See “Plan of Distribution (Conflicts of Interest)” and “Use of Proceeds and Hedging” in the accompanying product supplement for PLUS.
Where you can find more information:	Morgan Stanley and MSFL have filed a registration statement (including a prospectus, as supplemented by the product supplement for PLUS and the index supplement) with the Securities and Exchange Commission, or SEC, for the offering to which this communication relates. You should read the prospectus in that registration statement, the product supplement for PLUS, the index supplement and any other documents relating to this offering that Morgan Stanley and MSFL have filed with the SEC for more complete information about Morgan Stanley, MSFL and this offering.

Annex A — S&P 500® Futures Excess Return Index

The S&P 500® Futures Excess Return Index (the “underlying index”) is an equity futures index calculated, maintained and published by S&P® Dow Jones Indices LLC (“S&P® ”). S&P® is a joint venture between S&P® Global, Inc. (majority owner) and CME Group Inc. (minority owner), owner of CME Group Index Services LLC. The underlying index is reported by Bloomberg under the ticker symbol “SPXFP.” All information contained in this document regarding the underlying index has been derived from publicly available information, without independent verification.

The underlying index is the excess return version of the S&P 500 Futures Index, which measures the performance of the nearest maturing quarterly E-mini S&P 500 futures contract trading on the Chicago Mercantile Exchange (“CME”). The underlying index includes a provision for the replacement of the E-mini futures contract as the contract approaches maturity (also referred to as “rolling” or “the roll”). This replacement occurs over a one-day rolling period every March, June, September and December, effective after the close of trading five business days preceding the last trading date of the E-mini S&P futures contract.

E-Mini S&P 500 Futures Contract

The underlying index is constructed from the front-month E-mini S&P 500 futures contract (the “futures contract”). Futures contracts are contracts that legally obligate the holder to buy or sell an asset at a predetermined delivery price during a specified future time period. The futures contract is rolled forward once a quarter, with one-third of the contract being rolled forward on each of the fourth, third, and second day prior to expiration.

The E-mini S&P 500 futures (“ES”) contracts are U.S. dollar-denominated futures contracts, based on the S&P 500® Index (the “reference index”), traded on the CME, representing a contract unit of $50 multiplied by the reference index, measured in cents per index point. The ES contracts listed for the nearest nine quarters, for each March, June, September and December, and the nearest three Decembers are available for trading. Trading of the ES contracts terminates at 9:30 A.M. Eastern time on the third Friday of the contract month. The daily settlement prices of the ES contracts are based on trading activity in the relevant contract (and in the case of a lead month also being the expiry month, together with trading activity on lead month-second month spread contracts) on the CME during a specified settlement period. The final settlement price of ES contracts is based on the opening prices of the component stocks in the reference index, determined on the third Friday of the contract month. For more information about the reference index, see “S&P® U.S. Indices—S&P 500® Index” in the accompanying index supplement.

Underlying Index Calculation

The underlying index, calculated from the price change of the futures contract, reflects the excess return of the S&P 500 Futures Index. The level of the underlying index on a trading day is calculated as follows:

IndexERd = IndexERd-1×(1 + CDRd)

where:

IndexERd-1	=	The Excess Return Index level on the preceding business day, defined as any date on which the index is calculated
CDRd	=	The Contract Daily return, defined as:
	where:
		t	=	The business day on which the calculation is made
		TDW0t	=	Total Dollar Weight Obtained on t, defined as: CRW1t-1 × DCRP1t + CRW2t-1 × DCRP2t
		TDWIt-1	=	Total Dollar Weight Invested on the business day preceding t, defined as: CRW1t-1× DCRP1t-1 + CRW2t-1 × DCRP2t-1
		CRW1	=	The contract roll weight of the first nearby contract expiration
		CRW2	=	The contract roll weight of the roll in contract expiration
		DCRP t	=	The Daily Contract Reference Price (the official closing price per futures contract, as designated by the relevant exchange) of the futures contract

The underlying index is calculated on an excess return basis, meaning that the level of the underlying index is determined by its weighted return reduced by the return that could be earned on a notional cash deposit at the notional interest rate, which is a rate equal to the federal funds rate.

Overview of Futures Markets

Futures contracts are traded on regulated futures exchanges, in the over-the-counter market and on various types of electronic trading facilities and markets. As of the date of this pricing supplement, the futures contract is an exchange-traded futures contract. A futures contract provides for a specified settlement month in which the cash settlement is made by the seller (whose position is therefore described as “short”) and acquired by the purchaser (whose position is therefore described as “long”).

No purchase price is paid or received on the purchase or sale of a futures contract. Instead, an amount of cash or cash equivalents must be deposited with the broker as “initial margin.” This amount varies based on the requirements imposed by the exchange clearing houses, but it may be lower than 5% of the notional value of the contract. This margin deposit provides collateral for the obligations of the parties to the futures contract.

By depositing margin, which may vary in form depending on the exchange, with the clearing house or broker involved, a market participant may be able to earn interest on its margin funds, thereby increasing the total return that it may realize from an investment in futures contracts. However, the underlying index is not a total return index and does not reflect interest that could be earned on funds notionally committed to the trading of futures contracts.

At any time prior to the expiration of a futures contract, a trader may elect to close out its position by taking an opposite position on the exchange on which the trader obtained the position, subject to the availability of a liquid secondary market. This operates to terminate the position and fix the trader’s profit or loss. Futures contracts are cleared through the facilities of a centralized clearing house and a brokerage firm that is a member of the clearing house. Futures exchanges may adopt rules and take other actions that affect trading, including imposing speculative position limits, maximum price fluctuations and trading halts and suspensions and requiring liquidation of contracts in certain circumstances.
