Fully and Unconditionally Guaranteed by Morgan Stanley

The current estimated value of the securities is approximately $956.40 per security, or within $45.00 of that estimate. The estimated value of the securities is determined using our own pricing and valuation models, market inputs and assumptions relating to the underlyings, instruments based on the underlyings, 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. See "Estimated Value of the Securities" on page 4.

The securities have complex features and investing in the securities involves risks not associated with an investment in ordinary debt securities. See "Risk Factors" beginning on page 12. All payments on the securities are subject to our credit risk.

If the securities have not been previously called, on each monthly contingent coupon payment date, you will either receive a contingent coupon payment or you will not receive a contingent coupon payment, depending on the closing level of the lowest performing underlying on the related monthly calculation day.

Step 1: Determine which underlying is the lowest performing underlying on the relevant determination. The lowest performing underlying on any calculation day is the underlying with the lowest performance factor on that calculation day. The performance factor of an underlying on a calculation day is its closing level on that calculation day as a percentage of its starting level (i.e., its closing level on that calculation day divided by its starting level).

Step 2: Determine whether a contingent coupon payment is paid on the applicable contingent coupon payment date based on the closing level of the lowest performing underlying on the relevant calculation day, as follows:

On the maturity date, if the securities have not been called prior to the maturity date, you will receive (in addition to the final contingent coupon payment, if any) a cash payment per security (the maturity payment amount) calculated as follows:

Step 1: Determine which underlying is the lowest performing underlying on the final calculation day. The lowest performing underlying on the final calculation day is the underlying with the lowest performance factor on the final calculation day. The performance factor of an underlying on the final calculation day is its closing level as a percentage of its starting level (i.e., its closing level on the final calculation day divided by its starting level).

Step 2: Calculate the maturity payment amount based on the closing level of the lowest performing underlying on the final calculation day, as follows:

The following hypothetical examples illustrate how to determine whether a contingent coupon payment is paid with respect to a calculation day and how to calculate the payment at maturity, if any, if the securities have not been called. The following examples are for illustrative purposes only. Whether you receive a contingent coupon payment will be determined by reference to the closing level of each underlying on each calculation day, and the amount you will receive at maturity, if any, will be determined by reference to the closing level of each underlying on the final calculation day. The actual starting level, coupon threshold level and downside threshold level for each underlying and the actual contingent coupon rate will be determined on the pricing date. All payments on the securities, if any, are subject to our credit risk. The numbers in the hypothetical examples below may have been rounded for the ease of analysis. The below examples are based on the following terms*:

*The hypothetical starting level of 100 for the underlyings has been chosen for illustrative purposes only and does not represent the actual starting level of any underlying. The actual starting levels, coupon threshold levels and downside threshold levels will be determined on the pricing date and will be set forth under "Terms" above. For historical data regarding the actual closing levels of the underlyings, see the historical information set forth herein.

**The actual contingent coupon payment will be an amount determined by the calculation agent based on the actual contingent coupon rate. The hypothetical contingent monthly coupon of $9.333 is used in these examples for ease of analysis.

Principal at Risk Securities Linked to the Lowest Performing of the S&P 500® Index, the Russell 2000® Index and the Nasdaq-100® Technology Sector IndexSM due July 13, 2029

How to determine whether a contingent coupon payment is payable with respect to a calculation day (if the securities have not been previously called):

On hypothetical calculation day 1, the closing level of each underlying is at or above the respective coupon threshold level. Therefore, a contingent coupon payment of $9.333 is paid on the relevant contingent coupon payment date.

On each of hypothetical calculation days 2 and 3, at least one underlying closes at or above its respective coupon threshold level, but one or both of the other underlyings close below their respective coupon threshold levels. Therefore, no contingent coupon payment is paid on the relevant contingent coupon payment date.

On hypothetical calculation day 4, each underlying closes below its respective coupon threshold level, and, accordingly no contingent monthly coupon is paid on the relevant coupon payment date.

If the closing level of any underlying is less than its respective coupon threshold level on each calculation day, you will not receive any contingent coupon payments for the entire term of the securities.

How to calculate the payment investors will receive at maturity (if the securities have not been previously called):

The examples below illustrate how to calculate the payment at maturity if the securities have not been called prior to maturity

In example 1, the closing level of each underlying on the final calculation day is at or above its respective downside threshold level and coupon threshold level. Therefore, investors receive at maturity a cash payment per security equal to the face amount of the securities, in addition to the final contingent coupon payment. Investors do not participate in any appreciation in any underlying.

Principal at Risk Securities Linked to the Lowest Performing of the S&P 500® Index, the Russell 2000® Index and the Nasdaq-100® Technology Sector IndexSM due July 13, 2029

In example 2, the closing levels of two of the underlyings on the final calculation day are at or above their downside threshold levels, but the closing level of the other underlying on the final calculation day is below its respective downside threshold level. Therefore, investors are exposed to the downside performance of the lowest performing underlying at maturity. Investors receive at maturity an amount equal to the face amount multiplied by the performance factor of the RTY Index, which is the lowest performing underlying in this example.

In example 3, the closing levels of two of the underlyings on the final calculation day are at or above their downside threshold levels and the closing level of the other underlying on the final calculation day is below its respective downside threshold level. Therefore, investors are exposed to the downside performance of the lowest performing underlying at maturity. Investors receive at maturity an amount equal to the face amount the performance factor of the SPX Index, which is the lowest performing underlying in this example.

In example 4, the closing level of each underlying on the final calculation day is below its respective downside threshold level, and investors receive at maturity an amount equal to the face amount multiplied by the performance factor of the lowest performing underlying. Therefore, the maturity payment amount equals the face amount multiplied by the performance factor of the NDXT Index, which is the lowest performing underlying in this example.

If the securities have not been called prior to maturity and the closing level of any underlying on the final calculation day is below its respective downside threshold level, you will be exposed to the downside performance of the lowest performing underlying at maturity, and your maturity payment amount will be less than 70% of the face amount per security and could be zero.

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

Risks Relating to an Investment in the Securities

￭The securities do not guarantee the return of the face amount of your securities at maturity. The terms of the securities differ from those of ordinary debt securities in that they do not guarantee the return of the face amount of your securities at maturity. If the securities have not been previously called and if the closing level of any underlying on the final calculation day is less than its respective downside threshold level of 70% of its starting level, you will be exposed to the decline in the value of the lowest performing underlying, as compared to its starting level, on a 1-to-1 basis, and you will receive for each security that you hold at maturity an amount equal to the face amount multiplied by the performance factor of the lowest performing underlying. In this case, you will lose more than 30%, and possibly all, of the face amount of your securities at maturity.

￭The securities do not provide for the regular payment of interest. The terms of the securities differ from those of ordinary debt securities in that they do not provide for the regular payment of interest. Instead, the securities will pay a contingent coupon payment but only if the closing level of each underlying is at or above its respective coupon threshold level on the related calculation day. If the closing level of any underlying is lower than its coupon threshold level on the relevant calculation day for any interest period, we will pay no contingent coupon payment on the applicable contingent coupon payment date. It is possible that the closing level of any underlying will be less than its respective coupon threshold level for extended periods of time or even throughout the entire term of the securities so that you will receive few or no contingent coupon payments. If you do not earn sufficient contingent coupon payments over the term of the securities, the overall return on the securities may be less than the amount that would be paid on a conventional debt security of ours of comparable maturity.

￭The securities have early redemption risk. The term of the securities, and thus your opportunity to earn a potentially above-market coupon if the closing level of each underlying is greater than or equal to the coupon threshold level for such underlying on any calculation day, will be limited if we call the securities based on the output of a risk neutral valuation model on any redemption date. The term of your investment in the securities may be limited to as short as six months. In accordance with the risk neutral valuation model determination noted herein, it is more likely that we will call the securities when it would be advantageous for you to continue to hold the securities. As such, we will be more likely to call the securities when the closing level of each underlying on the calculation days is at or above the coupon threshold level for such underlying, which would otherwise result in an amount of interest payable on the securities that is greater than instruments of a comparable maturity and credit rating trading in the market. In other words, we will be more likely to call the securities at a time when the securities are paying an above-market coupon. If the securities are called prior to maturity, you will receive no more contingent coupon payments, may be forced to invest in a lower interest rate environment and may not be able to reinvest at comparable terms or returns.

On the other hand, we will be less likely to call the securities when the closing level of any underlying is below the respective coupon threshold level and/or when the closing level for any underlying is expected to be below the respective downside threshold level, such that you will receive no contingent coupon payments and/or that you will suffer a significant loss on your initial investment in the securities at maturity. Therefore, if we do not call the securities, it is more likely that you will receive few or no contingent coupon payments and suffer a significant loss at maturity.

￭The contingent coupon payment, if any, is based on the value of each underlying on only the related monthly calculation day. Whether the contingent coupon payment will be paid on any contingent coupon payment date will be determined at the end of the relevant interest period based on the closing level of each underlying on the relevant monthly calculation day. As a result, you will not know whether you will receive the contingent coupon payments on any contingent coupon payment date until near the end of the relevant interest period. Moreover, because the contingent coupon payment is based solely on the value of each underlying on the monthly calculation days, if the closing level of any underlying on any calculation day date is below the coupon threshold level for such underlying, you will not receive the contingent coupon payment for the related interest period, even if the level of such underlying was at or above its respective coupon threshold level on other days during that interest period, and even if the closing levels(s) of one or both of the other underlyings are at or above their respective coupon threshold level(s).

￭Investors will not participate in any appreciation in any underlying. Investors will not participate in any appreciation in any underlying from the starting level for such underlying, and the return on the securities will be limited to the contingent coupon payments, if any, that are paid with respect to each calculation day on which the closing level of each underlying is greater than or equal to its respective coupon threshold level, if any.

Principal at Risk Securities Linked to the Lowest Performing of the S&P 500® Index, the Russell 2000® Index and the Nasdaq-100® Technology Sector IndexSM due July 13, 2029

￭The market price will be influenced by many unpredictable factors. Several factors, many of which are beyond our control, will influence the value of the securities in the secondary market and the price at which MS & Co. may be willing to purchase or sell the securities in the secondary market. We expect that generally the level of interest rates available in the market and the value of each underlying on any day, including in relation to its respective coupon threshold level and downside threshold level, will affect the value of the securities more than any other factors. Other factors that may influence the value of the securities include:

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

owhether the closing level of any underlying has been below its respective coupon threshold level on any calculation day,

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

odividend rates on the securities underlying the underlyings,

othe time remaining until the securities mature,

ointerest and yield rates in the market,

othe availability of comparable instruments,

othe composition of the underlyings and changes in the constituent stocks of such underlyings, and

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

Generally, the longer the time remaining to maturity, the more the market price of the securities will be affected by the other factors described above. Some or all of these factors will influence the price that you will receive if you sell your securities prior to maturity. In particular, if any underlying has closed near or below its coupon threshold level, and especially if any underlying has closed near or below its downside threshold level, the market value of the securities is expected to decrease substantially, and you may have to sell your securities at a substantial discount from the face amount of your securities.

You cannot predict the future performance of any underlying based on its historical performance. The value of any underlying may decrease and be below the respective coupon threshold level for such underlying on each calculation day so that you will receive no return on your investment, and any or all of the underlyings may close below the respective downside threshold level(s) on the final calculation day so that you will lose a significant portion or all of your initial investment in the securities. There can be no assurance that the closing level of each underlying will be at or above the respective coupon threshold level on any calculation day so that you will receive a coupon payment on the securities for the applicable interest period, or that it will be at or above its respective downside threshold level on the final calculation day so that you do not suffer a significant loss on your initial investment in the securities. See "S&P 500® Index Overview," "Russell 2000® Index Overview" and "Nasdaq-100® Technology Sector IndexSM Overview" below.

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

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

￭Investing in the securities is not equivalent to investing in the underlyings. Investing in the securities is not equivalent to investing in the underlyings or the component stocks or any underlying. Investors in the securities will not participate in any positive performance of any underlying, and will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the stocks that constitute any underlying.

￭The rate we are willing to pay for securities of this type, maturity and issuance size is likely to be lower than the rate implied by our secondary market credit spreads and advantageous to us. Both the lower rate and the inclusion of costs associated with issuing, selling, structuring and hedging the securities in the face amount reduce the economic terms of the securities, cause the estimated value of the securities to be less than the face amount and will adversely affect secondary market prices. Assuming no change in market conditions or any other

Market Linked Securities-Callable with Contingent Coupon and Contingent Downside

Principal at Risk Securities Linked to the Lowest Performing of the S&P 500® Index, the Russell 2000® Index and the Nasdaq-100® Technology Sector IndexSM due July 13, 2029

relevant factors, the prices, if any, at which dealers, including MS & Co., may be willing to purchase the securities in secondary market transactions will likely be significantly lower than the face amount, because secondary market prices will exclude the issuing, selling, structuring and hedging-related costs that are included in the face amount and borne by you and because the secondary market prices will reflect our secondary market credit spreads and the bid-offer spread that any dealer would charge in a secondary market transaction of this type as well as other factors.

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

However, because the costs associated with issuing, selling, structuring and hedging the securities are not fully deducted upon issuance, for a period of up to 3 months following the issue date, to the extent that MS & Co. may buy or sell the securities in the secondary market, absent changes in market conditions, including those related to the underlyings, and to our secondary market credit spreads, it would do so based on values higher than the estimated value, and we expect that those higher values will also be reflected in your brokerage account statements.

￭The estimated value of the securities is determined by reference to our pricing and valuation models, which may differ from those of other dealers and is not a maximum or minimum secondary market price. These pricing and valuation models are proprietary and rely in part on subjective views of certain market inputs and certain assumptions about future events, which may prove to be incorrect. As a result, because there is no market-standard way to value these types of securities, our models may yield a higher estimated value of the securities than those generated by others, including other dealers in the market, if they attempted to value the securities. In addition, the estimated value on the pricing date does not represent a minimum or maximum price at which dealers, including MS & Co., would be willing to purchase your securities in the secondary market (if any exists) at any time. The value of your securities at any time after the date of this document will vary based on many factors that cannot be predicted with accuracy, including our creditworthiness and changes in market conditions. See also "The market price will be influenced by many unpredictable factors" above.

￭The securities will not be listed on any securities exchange and secondary trading may be limited. The securities will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the securities. MS & Co. and WFS may, but are not obligated to, make a market in the securities and, if either of them once chooses to make a market, may cease doing so at any time. When they do make a market, they will generally do so for transactions of routine secondary market size at prices based on their respective estimates of the current value of the securities, taking into account their respective bid/offer spreads, 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 they will be able to resell the securities. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the securities easily. Since other broker-dealers may not participate significantly in the secondary market for the securities, the price at which you may be able to trade your securities is likely to depend on the price, if any, at which MS & Co. or WFS is willing to transact. If, at any time, MS & Co. and WFS were to cease making a market in the securities, it is likely that there would be no secondary market for the securities. Accordingly, you should be willing to hold your securities to maturity.

￭The calculation agent, which is a subsidiary of Morgan Stanley and an affiliate of MSFL, will make determinations with respect to the securities. As calculation agent, MS & Co. will determine the starting levels, the coupon threshold levels and the downside threshold levels and will calculate the amount of cash you receive at maturity, if any. Moreover, certain determinations made by MS & Co., in its capacity as calculation agent, may require it to exercise discretion and make subjective judgments, such as with respect to the occurrence or non-occurrence of market disruption events and the selection of a successor index or calculation of a closing level in the event of a market disruption event or discontinuance of any of the underlyings. These potentially subjective determinations may adversely affect the payout to you at maturity, if any. For further information regarding these types of determinations, see "General Terms of the Securities-Market Disruption Events," "-Adjustments to an Index," "-Discontinuance of an Index," "General Terms of the Securities-Consequences of a Market Disruption Event; Postponement of a Calculation Day" and "Alternate Exchange Calculation in Case of an Event of Default" in the accompanying product supplement for principal at risk securities. In addition, MS & Co. has determined the estimated value of the securities on the pricing date.

￭Hedging and trading activity by our affiliates could potentially adversely affect the value of the securities. One or more of our affiliates and/or third-party dealers expect to carry out hedging activities related to the securities (and possibly to other instruments linked to the underlyings or the component stocks of the underlyings), including trading in the stocks that constitute the underlyings as well as in other instruments related to the underlyings. As a result, these entities may be unwinding or adjusting hedge positions during the term of the securities, and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the final calculation day approaches. Some of our affiliates also trade the stocks that constitute the underlyings and other financial instruments related to the underlyings 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 affect the starting level of an underlying, and, therefore, could increase (i) the level at or above which such underlying must close on each calculation day in

Principal at Risk Securities Linked to the Lowest Performing of the S&P 500® Index, the Russell 2000® Index and the Nasdaq-100® Technology Sector IndexSM due July 13, 2029

order for you to earn a contingent coupon payment (depending also on the performance of the other underlyings) and (ii) the level at or above which such underlying must close on the final calculation day so that you are not exposed to the negative performance of the lowest performing underlying at maturity (depending also on the performance of the other underlyings). Additionally, such hedging or trading activities during the term of the securities could potentially affect the value of any underlying on the calculation days, and, accordingly, whether we pay a contingent coupon payment on the securities and the amount of cash you will receive at maturity, if any.

￭The maturity date may be postponed if the final calculation day is postponed. If the scheduled final calculation day is not a trading day or if a market disruption event occurs on that day so that the final calculation day is postponed and falls less than three business days prior to the maturity date, the maturity date of the securities will be postponed to the third business day following that final calculation day as postponed.

￭Potentially inconsistent research, opinions or recommendations by Morgan Stanley, MSFL, WFS or our or their respective affiliates. Morgan Stanley, MSFL, WFS and our or their respective affiliates may publish research from time to time on financial markets and other matters that may influence the value of the securities, or express opinions or provide recommendations that are inconsistent with purchasing or holding the securities. Any research, opinions or recommendations expressed by Morgan Stanley, MSFL, WFS or our or their respective affiliates may not be consistent with each other and may be modified from time to time without notice. Investors should make their own independent investigation of the merits of investing in the securities and the underlyings to which the securities are linked.

￭The U.S. federal income tax consequences of an investment in the securities offered by this pricing supplement are uncertain. There is no direct legal authority regarding the proper U.S. federal income tax treatment of the securities, and significant aspects of the tax treatment of the securities are uncertain. Moreover, non-U.S. investors should note that persons having withholding responsibility in respect of the securities are, absent an exception, expected to withhold on any coupon paid to a non-U.S. investor, generally at a rate of 30%. We will not pay any additional amounts in respect of such withholding. You should review carefully the section entitled "United States Federal Income Tax Considerations" herein, in combination with the section entitled "United States Federal Taxation" in the accompanying tax supplement, and consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the securities.

Risks Relating to the Underlyings

￭You are exposed to the price risk of each underlying. Your return on the securities is not linked to a basket consisting of each underlying. Rather, it will be contingent upon the independent performance of each underlying. Unlike an instrument with a return linked to a basket of underlying assets, in which risk is mitigated and diversified among all the components of the basket, you will be exposed to the risks related to each underlying. Poor performance by any underlying over the term of the securities may negatively affect your return and will not be offset or mitigated by any positive performance by the other underlyings. To receive any contingent coupon payments, each underlying must close at or above its respective coupon threshold level on the applicable calculation day. In addition, if the securities have not been called and any underlying has declined to below its respective downside threshold level as of the final calculation day, you will be fully exposed to the decline in the lowest performing underlying over the term of the securities on a 1-to-1 basis, even if the other underlyings have appreciated or have not declined as much. Under this scenario, the value of any such maturity payment amount will be less than 70% of the face amount of your securities and could be zero. Accordingly, your investment is subject to the price risk of each underlying.

￭Because the securities are linked to the performance of the lowest performing underlying, you are exposed to greater risks of receiving no contingent coupon payments and sustaining a significant loss on your investment than if the securities were linked to just one underlying. The risk that you will not receive any contingent coupon payments, or that you will suffer a significant loss on your investment, is greater if you invest in the securities as opposed to substantially similar securities that are linked to the performance of just one underlying. With three underlyings, it is more likely that any underlying will close below its coupon threshold level on any calculation day, and below its downside threshold level on the final calculation day, than if the securities were linked to only one underlying. Therefore, it is more likely that you will not receive any contingent coupon payments and that you will suffer a significant loss on your investment.

￭The securities are linked to the Russell 2000® Index and are subject to risks associated with small-capitalization companies. As the Russell 2000® Index is one of the underlyings, and the Russell 2000® Index consists of stocks issued by companies with relatively small market capitalization, the securities are linked to the value of small-capitalization companies. These companies often have greater stock price volatility, lower trading volume and less liquidity than large-capitalization companies and therefore the Russell 2000® Index may be more volatile than underlyings that consist of stocks issued by large-capitalization companies. Stock prices of small-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business and economic developments, and the stocks of small-capitalization companies may be thinly traded. In addition, small capitalization companies are typically less well-established and less stable financially than large-capitalization companies and may depend on a small number of key personnel, making them more vulnerable to loss of personnel.

companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and less competitive strengths than large-capitalization companies and are more susceptible to adverse developments related to their products.

￭Investing in the securities exposes investors to risks associated with investments in securities with a concentration in the technology sector. The stocks included in the Nasdaq-100® Technology Sector IndexSM are stocks of companies whose primary business is directly associated with the technology sector, including the following sub-sectors: computers and peripherals, software, diversified telecommunication services, communications equipment, semiconductors and semiconductor equipment, internet software and services, IT services, electronic equipment, instruments and components, wireless telecommunication services and office electronics. Because the value of the securities is linked to the performance of the Nasdaq-100® Technology Sector IndexSM, an investment in the securities exposes investors to risks associated with investments in securities with a concentration in the technology sector. The values of stocks of technology companies and companies that rely heavily on technology are particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Additionally, companies in the technology sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel. All of these factors could have an effect on the price of the Nasdaq-100® Technology Sector IndexSM and, therefore, on the value of the securities.

￭Adjustments to the underlyings could adversely affect the value of the securities. The publisher of any underlying may add, delete or substitute the stocks constituting such underlying or make other methodological changes that could change the value of such underlying. The publisher of such underlying may discontinue or suspend calculation or publication of such underlying at any time. In these circumstances, the calculation agent will have the sole discretion to substitute a successor underlying that is comparable to the discontinued underlying and is permitted to consider underlyings 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 underlying on any calculation day, the determination of whether a contingent coupon payment will be payable on the securities on the applicable contingent coupon payment date and/or the amount payable at maturity, if any, will be based on the value of such underlying, based on the closing prices of the stocks constituting such underlying at the time of such discontinuance, without rebalancing or substitution, computed by MS & Co. as calculation agent in accordance with the formula for calculating such underlying last in effect prior to such discontinuance, as compared to the relevant starting level, coupon threshold level or downside threshold level, as applicable (depending also on the performance of the other underlyings).

￭Historical levels of the underlyings should not be taken as an indication of the future performance of the underlyings during the term of the securities. No assurance can be given as to the level of the underlyings at any time, including on the final calculation day, because historical levels of the underlyings do not provide an indication of future performance of the underlyings.

United States federal income tax considerations

You should review carefully the section in the accompanying tax supplement entitled "United States Federal Taxation." The following discussion, when read in combination with that section, constitutes the full opinion of our counsel, Davis Polk & Wardwell LLP, regarding the material U.S. federal income tax consequences of owning and disposing of the securities offered by this pricing supplement.

Generally, this discussion assumes that you purchased a security for cash in the original issuance at the stated issue price and does not address other circumstances specific to you, including consequences that may arise due to any other investments relating to an underlier. Moreover, as discussed in the section entitled "United States Federal Taxation" in the accompanying tax supplement, we have not attempted to ascertain whether any issuer of any underlier to which the securities relate is a U.S. real property holding corporation or a passive foreign investment company. You should consult your tax adviser regarding these issues, including the effect any circumstances specific to you may have on the U.S. federal income tax consequences of your ownership of a security.

In the opinion of our counsel, which is based on current market conditions, it is reasonable to treat the securities for U.S. federal income tax purposes as prepaid financial contracts with associated coupons, and any coupons as ordinary income, as described in the section entitled "United States Federal Taxation-Tax Consequences to U.S. Holders-Program Securities Treated as Prepaid Financial Contracts with Associated Coupons" in the accompanying tax supplement. There is uncertainty regarding this treatment, and the Internal Revenue Service (the "IRS") or a court might not agree with it. Moreover, because this treatment of the securities and our counsel's opinion are based on market conditions as of the date of this preliminary pricing supplement, each is subject to confirmation on the pricing date. A different tax treatment could be adverse to you.

We do not plan to request a ruling from the IRS regarding the treatment of the securities. An alternative characterization of the securities could materially and adversely affect the tax consequences of ownership and disposition of the securities, including the timing and character of income recognized. In particular, due to the terms of the securities and current market conditions, there is a risk that the securities could be characterized as debt instruments for U.S. federal income tax purposes, in which case the timing and character of income recognized in respect of the securities could be different from those described herein and possibly adverse to certain investors. In addition, the U.S. Treasury Department and the IRS have requested comments on various issues regarding the U.S. federal income tax treatment of "prepaid forward contracts" and similar financial instruments and have indicated that such transactions may be the subject of future regulations or other guidance. Furthermore, members of Congress have proposed legislative changes to the tax treatment of derivative contracts. Any legislation, Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, possibly with retroactive effect.

Non-U.S. Holders. If you are a Non-U.S. Holder (as defined in the accompanying tax supplement), please also read the section entitled "United States Federal Taxation-Tax Consequences to Non-U.S. Holders-Program Securities Not Treated as Debt Instruments" in the accompanying tax supplement.

The U.S. federal income tax treatment of the coupons is unclear. To the extent that we have withholding responsibility in respect of the securities, we would expect generally to treat the coupons paid to Non-U.S. Holders as subject to U.S. withholding tax. Moreover, you should expect that, if the applicable withholding agent determines that withholding tax should apply, it will be at a rate of 30% (or lower treaty rate). In order to claim an exemption from, or a reduction in, the 30% withholding under an applicable treaty, you may need to comply with certification requirements to establish that you are not a U.S. person and are eligible for such an exemption or reduction under an applicable tax treaty. You should consult your tax adviser regarding the tax treatment of the coupons.

As discussed under "United States Federal Taxation-Tax Consequences to Non-U.S. Holders-Dividend Equivalents under Section 871(m) of the Code" in the accompanying tax supplement, Section 871(m) of the Internal Revenue Code and Treasury regulations promulgated thereunder ("Section 871(m)") generally impose a 30% 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. The Treasury regulations, as modified by an IRS notice, exempt financial instruments issued prior to January 1, 2027 that do not have a "delta" of one. Based on certain determinations made by us, we expect that Section 871(m) will not apply to the securities with regard to Non-U.S. Holders. Our determination is not binding on the IRS, and the IRS may disagree with this determination. If necessary, further information regarding the potential application of Section 871(m) will be provided in the final pricing supplement for the securities.

We will not be required to pay any additional amounts with respect to U.S. federal withholding taxes.

You should consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments, as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.
