Market Linked Securities-Callable with Contingent Coupon and Contingent Downside

Principal at Risk Securities Linked to the Lowest Performing of the Energy Select Sector SPDR^® Fund, the Technology Select Sector SPDR^® Fund and the Industrial Select Sector SPDR^® Fund due May 4, 2028

Fully and Unconditionally Guaranteed by Morgan Stanley

§	Linked to the lowest performing of the Energy Select Sector SPDR® Fund, the Technology Select Sector SPDR® Fund and the Industrial Select Sector SPDR® Fund (each referred to as an "underlying")

§

The securities offered are unsecured obligations of Morgan Stanley Finance LLC ("MSFL") and are fully and unconditionally guaranteed by Morgan Stanley. Unlike ordinary debt securities, the securities do not guarantee the payment of interest, do not guarantee the repayment of principal and are subject to potential redemption prior to the maturity date upon the terms described below. The securities have the terms described in the accompanying product supplement for principal at risk securities, index supplement and prospectus, as supplemented or modified by this document.

§

Contingent Coupon. The securities will pay a contingent coupon on a quarterly basis until the stated maturity date or earlier redemption if, and only if, the fund closing price of the lowest performing underlying on the calculation day for that quarter is greater than or equal to its coupon threshold price. However, if the fund closing price of the lowest performing underlying on a calculation day is less than its coupon threshold price, you will not receive any contingent coupon for the relevant quarter. If the fund closing price of the lowest performing underlying is less than its coupon threshold price on every calculation day, you will not receive any contingent coupons throughout the entire term of the securities. The coupon threshold price for each underlying is equal to 70% of its starting price. The contingent coupon rate will be determined on the pricing date and will be at least 11.45% per annum.

§

Call Feature. Beginning approximately six months after issuance, on any redemption date we will redeem the securities for a redemption payment equal to the face amount plus a final contingent coupon payment, if any, if and only if the output of a risk neutral valuation model on a business day, as selected by the calculation agent, that is no earlier than three business days before the calculation day preceding such redemption date and no later than such calculation day, based on the inputs indicated under "Terms-Call feature" below, indicates that redeeming on such date is economically rational for us as compared to not redeeming on such date. An early redemption of the securities will not automatically occur based on the performance of the underlyings.

§

Potential Loss of Principal. If the securities are not previously called, you will receive the face amount at maturity if, and only if, the fund closing price of each underlying on the final calculation day is greater than or equal to its respective downside threshold price. If the fund closing price of any underlying on the final calculation day is less than its respective downside threshold price, investors will be fully exposed to the decline in the lowest performing underlying on a 1-to-1 basis, and will receive a maturity payment amount that is less than 70% of the face amount of the securities and could be zero.

§	Accordingly, investors in the securities must be willing to accept the risk of losing their entire initial investment and also the risk of not receiving any contingent coupon payments throughout the entire term of the securities.

§

Because all payments on the securities are based on the lowest performing underlying, a decline beyond the respective coupon threshold price or respective downside threshold price of any underlying will result in no contingent coupon payments or a significant loss of your investment, as applicable, even if the other underlyings have appreciated or have not declined as much.

§

The securities are for investors who are willing to risk their principal based on the lowest performing of three underlyings and who seek an opportunity to earn interest at a potentially above-market rate in exchange for the risk of receiving no contingent coupon payments over the entire term of the securities.

§	Investors will not participate in any appreciation of any underlying.

§	The securities are notes issued as part of MSFL's Series A Global Medium-Term Notes program.

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

§	These securities are not secured obligations and you will not have any security interest in, or otherwise have any access to, any securities included in any of the underlyings.

The current estimated value of the securities is approximately $961.40 per security, or within $30.00 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 11. All payments on the securities are subject to our credit risk.

The Securities and Exchange Commission and state securities regulators have not approved or disapproved these securities, or determined if this document or the accompanying product supplement, index supplement and prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The securities are not deposits or savings accounts and are not insured by the Federal Deposit Insurance Corporation or any other governmental agency or instrumentality, nor are they obligations of, or guaranteed by, a bank.

Estimated Value of the Securities

The face amount of each security is $1,000. This price includes costs associated with issuing, selling, structuring and hedging the securities, which are borne by you, and, consequently, the estimated value of the securities on the pricing date will be less than $1,000 per security. We estimate that the value of each security on the pricing date will be approximately $961.40, or within $30.00 of that estimate. Our estimate of the value of the securities 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 securities on the pricing date, we take into account that the securities comprise both a debt component and a performance-based component linked to the underlyings. 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.

What determines the economic terms of the securities?

In determining the economic terms of the securities, including the contingent coupon rate, the coupon threshold prices and the downside threshold prices, we use an internal funding rate which is likely to be lower than our secondary market credit spreads and therefore advantageous to us. If the issuing, selling, structuring and hedging costs borne by you were lower or if the internal funding rate were higher, one or more of the economic terms of the securities would be more favorable to you.

What is the relationship between the estimated value on the pricing date and the secondary market price of the securities?

The price at which MS & Co. purchases the securities in the secondary market, absent changes in market conditions, including those related to the underlyings, may vary from, and be lower than, the estimated value on the pricing date, because the secondary market price takes into account our secondary market credit spread as well as the bid-offer spread that MS & Co. would charge in a secondary market transaction of this type and other factors. However, because the costs associated with issuing, selling, structuring and hedging the securities are not fully deducted upon issuance, for a period of up to 4 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. We expect that those higher values will also be reflected in your brokerage account statements.

MS & Co. may, but is not obligated to, make a market in the securities and, if it once chooses to make a market, may cease doing so at any time.

Investor Considerations

The Principal at Risk Securities Linked to the Lowest Performing of the Energy Select Sector SPDR^® Fund, the Technology Select Sector SPDR^® Fund and the Industrial Select Sector SPDR^® Fund due May 4, 2028 (the "securities") may be appropriate for investors who:

§

Seek an investment with contingent coupon payments at a rate of at least 11.45% per annum (to be determined on the pricing date) until the stated maturity date or earlier redemption, if, and only if, the fund closing price of each underlying on the applicable quarterly calculation day is greater than or equal to 70% of its starting price;

§

Understand that if the fund closing price of any underlying on the final calculation day has declined by more than 30% from its starting price, they will be fully exposed to the decline in the lowest performing underlying from its starting price and will lose more than 30%, and possibly all, of the face amount of their securities at maturity;

§	Are willing to accept the risk that they may receive few or no contingent coupon payments over the term of the securities;

§	Understand that the securities may be called prior to the maturity date and that the term of the securities may be as short as approximately six months;

§	Understand that the return on the securities will depend solely on the performance of the underlying that is the lowest performing underlying on each calculation day and that they will not benefit in any way from the performance of the better performing underlyings;

§	Understand that the securities are riskier than alternative investments linked to only one of the underlyings or linked to a basket composed of each underlying;

§	Understand and are willing to accept the full downside risks of each underlying;

§	Are willing to forgo participation in any appreciation of any underlying, fixed interest payments on the securities and dividends on the underlyings and the stocks composing the fund underlying indices; and

§	Are willing to hold the securities until maturity.

The securities are not designed for, and may not be an appropriate investment for, investors who:

§	Seek a liquid investment or are unable or unwilling to hold the securities to maturity;

§	Require full payment of the face amount of the securities at maturity;

§	Seek a security with a fixed term;

§	Are unwilling to accept the risk that the fund closing price of any underlying on the final calculation day may decline by more than 30% from its respective starting price to its respective ending price, in which case they will lose a significant portion or all of their investment;

§	Seek current income;

§	Are unwilling to accept the risk of exposure to each of the underlyings;

§	Seek exposure to a basket composed of each underlying or a similar investment in which the overall return is based on a blend of the performances of the underlyings, rather than solely on the lowest performing underlying;

§	Seek exposure to the upside performance of any or each underlying;

§	Are unwilling to accept our credit risk; or

§	Prefer the lower risk of fixed income investments with comparable maturities issued by companies with comparable credit ratings.

The considerations identified above are not exhaustive. Whether or not the securities are an appropriate investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisors have carefully considered the appropriateness of an investment in the securities in light of your particular circumstances. You should also review carefully the "Risk Factors" herein and in the accompanying product supplement for risks related to an investment in the securities. For more information about the underlyings, please see the sections titled "Energy Select Sector SPDR^® Fund Overview," "Technology Select Sector SPDR^® Fund Overview" and "Industrial Select Sector SPDR^® Fund Overview" below.

Determining Payment on a Contingent Coupon Payment Date and on the Maturity Date

If the securities have not been previously called, on each quarterly contingent coupon payment date, you will either receive a contingent coupon payment or you will not receive a contingent coupon payment, depending on the fund closing price of the lowest performing underlying on the related quarterly 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 fund closing price on that calculation day as a percentage of its starting price (i.e., its fund closing price on that calculation day divided by its starting price).

Step 2: Determine whether a contingent coupon payment is paid on the applicable contingent coupon payment date based on the fund closing price 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 fund closing price as a percentage of its starting price (i.e., its fund closing price on the final calculation day divided by its starting price).

Step 2: Calculate the maturity payment amount based on the ending price of the lowest performing underlying, as follows:

Scenario Analysis and Examples of Hypothetical Payments on the Securities

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 fund closing price of each underlying on each calculation day, and the amount you will receive at maturity, if any, will be determined by reference to the ending price of each underlying on the final calculation day. The actual starting price, coupon threshold price and downside threshold price 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*:

Hypothetical contingent coupon payment:	On each contingent coupon payment date, you will receive a contingent coupon payment at a per annum rate equal to the contingent coupon rate if, and only if, the fund closing price of the lowest performing underlying on the related calculation day is greater than or equal to its coupon threshold price. If payable, the contingent coupon payment will be an amount in cash per face amount corresponding to a return of 11.45% per annum for each interest payment period for each applicable calculation day. These hypothetical examples reflect a hypothetical contingent quarterly coupon rate of 11.45% (corresponding to $28.625 per quarter per security**).
Hypothetical starting price:	With respect to the XLE Shares: $100
	With respect to the XLK Shares: $100
	With respect to the XLI Shares: $100
Hypothetical coupon threshold price:	With respect to the XLE Shares: $70, which is 70% of its hypothetical starting price
	With respect to the XLK Shares: $70, which is 70% of its hypothetical starting price
	With respect to the XLI Shares: $70, which is 70% of its hypothetical starting price
Hypothetical downside threshold price:	With respect to the XLE Shares: $70, which is 70% of its hypothetical starting price
	With respect to the XLK Shares: $70, which is 70% of its hypothetical starting price
	With respect to the XLI Shares: $70, which is 70% of its hypothetical starting price

^* The hypothetical starting price of $100 for the underlyings has been chosen for illustrative purposes only and does not represent the actual starting price of any underlying. The actual starting prices, coupon threshold prices and downside threshold prices will be determined on the pricing date and will be set forth under "Terms" above. For historical data regarding the actual closing prices 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 quarterly coupon of $28.625 is used in these examples for ease of analysis.

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

Date	XLE Shares Fund Closing Price	XLK Shares Fund Closing Price	XLI Shares Fund Closing Price	Contingent Coupon Payment (per Security)
Hypothetical Calculation Day 1	$90 (at or above the coupon threshold price)	$95 (at or above the coupon threshold price)	$135 (at or above the coupon threshold price)	$28.625
Hypothetical Calculation Day 2	$60 (below the coupon threshold price)	$55 (below the coupon threshold price)	$120 (at or above the coupon threshold price)	$0
Hypothetical Calculation Day 3	$90 (at or above the coupon threshold price)	$85 (at or above the coupon threshold price)	$40 (below the coupon threshold price)	$0
Hypothetical Calculation Day 4	$60 (below the coupon threshold price)	$45 (below the coupon threshold price)	$50 (below the coupon threshold price)	$0

On hypothetical calculation day 1, the fund closing price of each underlying is at or above the respective coupon threshold price. Therefore, a contingent coupon payment of $28.625 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 price, but one or both of the other underlyings close below their respective coupon threshold prices. 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 price, and, accordingly no contingent quarterly coupon is paid on the relevant coupon payment date.

If the fund closing price of any underlying is less than its respective coupon threshold price 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

	XLE Shares Ending Price	XLK Shares Ending Price	XLI Shares Ending Price	Maturity Payment Amount (per Security)
Example 1:	$150 (at or above the downside threshold price and coupon threshold price)	$130 (at or above the downside threshold price and coupon threshold price)	$142 (at or above the downside threshold price and coupon threshold price)	$1,028.625 (the face amount plus the final contingent coupon payment)
Example 2:	$125 (at or above the downside threshold price)	$135 (at or above the downside threshold price)	$40 (below the downside threshold price)	$1,000 × ($40 / $100) = $400
Example 3:	$20 (below the downside threshold price)	$75 (at or above the downside threshold price)	$120 (at or above the downside threshold price)	$1,000 × ($20 / $100) = $200
Example 4:	$45 (below the downside threshold price)	$35 (below the downside threshold price)	$20 (below the downside threshold price)	$1,000 × ($20 / $100) = $200

In example 1, the ending price of each underlying is at or above its respective downside threshold price and coupon threshold price. 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.

In example 2, the ending prices of two of the underlyings are at or above their respective downside threshold prices, but the ending price of the other underlying is below its respective downside threshold price. 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 times the performance factor of the XLI Shares, which is the lowest performing underlying in this example.

In example 3, the ending prices of two of the underlyings are at or above their respective downside threshold prices and the ending price of the other underlying is below its respective downside threshold price. 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 times the performance factor of the XLE Shares, which is the lowest performing underlying in this example.

In example 4, the ending price of each underlying is below its respective downside threshold price, and investors receive at maturity an amount equal to the face amount times the performance factor of the lowest performing underlying. Therefore, the maturity payment amount equals the face amount times the performance factor of the XLI Shares, which is the lowest performing underlying in this example.

If the securities have not been called prior to maturity and the ending price of any underlying is below its respective downside threshold price, 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.

Risk Factors

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

Risks Relating to an Investment in the Securities

§

The securities do not 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 ending price of any underlying is less than its respective downside threshold price of 70% of its starting price, you will be exposed to the decline in the value of the lowest performing underlying, as compared to its starting price, 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 times 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 fund closing price of each underlying is at or above its respective coupon threshold price on the related calculation day. If the fund closing price of any underlying is lower than its coupon threshold price on a calculation day, we will pay no contingent coupon payment on the applicable contingent coupon payment date. It is possible that the fund closing price of any underlying will be less than its respective coupon threshold price 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 fund closing price of each underlying is greater than or equal to the coupon threshold price 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 fund closing price of each underlying on the calculation days is at or above the coupon threshold price 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 fund closing price of any underlying is below the respective coupon threshold price and/or when the fund closing price for any underlying is expected to be below the respective downside threshold price, 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 quarterly 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 quarterly period based on the fund closing price of each underlying on the relevant quarterly 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 quarterly period. Moreover, because the contingent coupon payment is based solely on the value of each underlying on the quarterly calculation days, if the fund closing price of any underlying on any calculation day date is below the coupon threshold price for such

underlying, you will not receive the contingent coupon payment for the related quarterly period, even if the price of such underlying was at or above its respective coupon threshold price on other days during that quarterly period, and even if the fund closing prices(s) of one or both of the other underlyings are at or above their respective coupon threshold price(s).

§

Investors will not participate in any appreciation in any underlying. Investors will not participate in any appreciation in any underlying from the starting price 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 fund closing price of each underlying is greater than or equal to its respective coupon threshold price, if any.

§

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 price of each underlying on any day, including in relation to its respective coupon threshold price and downside threshold price, will affect the value of the securities more than any other factors. Other factors that may influence the value of the securities include:

o	the trading price and volatility (frequency and magnitude of changes in value) of the underlyings,

o	whether the fund closing price of any underlying has been below its respective coupon threshold price on any calculation day,

o	geopolitical conditions and economic, financial, political, regulatory or judicial events that affect the underlyings or securities markets generally and which may affect the price of each underlying,

o	dividend rates on the underlyings or the stocks composing the fund underlying indices,

o	the time remaining until the securities mature,

o	interest and yield rates in the market,

o	the availability of comparable instruments,

o	the occurrence of certain events affecting the underlyings that may or may not require an adjustment to an adjustment factor, and

o	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 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 price, and especially if any underlying has closed near or below its downside threshold price, 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 price of any underlying may decrease and be below the respective coupon threshold price 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 price(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 fund closing price of each underlying will be at or above the respective coupon threshold price on any calculation day so that you will receive a coupon payment on the securities for the applicable quarterly period, or that it will be at or above its respective downside threshold price on the final calculation day so that you do not suffer a significant loss on your initial investment in the securities. See "Energy Select Sector SPDR^® Fund Overview," "Technology Select Sector SPDR^® Fund Overview" and "Industrial Select Sector SPDR^® Fund 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 or the stocks composing the fund underlying indices. Investing in the securities is not equivalent to investing in the underlyings, the fund underlying indices or the stocks that constitute the fund underlying indices. 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 underlyings or the stocks that constitute the fund underlying indices.

§

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 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 4 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 prices, the coupon threshold prices, the downside threshold prices and the ending prices 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 fund closing price of an underlying in the event of a market disruption event with respect to such underlying or certain adjustments to an adjustment factor. 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," "-Anti-dilution Adjustments Relating to a Fund; Alternate Calculation," "-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 fund underlying indices), including trading in the underlyings and in other instruments related to the underlyings or fund underlying indices. 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 underlyings or the stocks that constitute the fund underlying indices and other financial instruments related to the fund underlying indices and 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 price of an underlying, and, therefore, could increase (i) the price at or above which such underlying must close on each calculation day in order for you to earn a contingent coupon payment (depending also on the performance of the other underlyings) and (ii) the price 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 price 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 are uncertain. There is no direct legal authority as to the proper treatment of the securities for U.S. federal income tax purposes, and, therefore, significant aspects of the tax treatment of the securities are uncertain.

Please read the discussion under "Additional Information About the Securities-Tax considerations" in this document concerning the U.S. federal income tax consequences of an investment in the securities. We intend to treat a security for U.S. federal income tax purposes as a single financial contract that provides for a coupon that will be treated as gross income to you at the time received or accrued, in accordance with your regular method of tax accounting. Under this treatment, the ordinary income treatment of the coupon payments, in conjunction with the capital loss treatment of any loss recognized upon the sale, exchange or settlement of the securities, could result in adverse tax consequences to holders of the securities because the deductibility of capital losses is subject to limitations. We do not plan to request a ruling from the Internal Revenue Service (the "IRS") regarding the tax treatment of the securities, and the IRS or a court may not agree with the tax treatment described herein. If the IRS were successful in asserting an alternative treatment for the securities, the timing and character of income or loss on the securities might differ significantly from the tax treatment described herein. For example, under one possible treatment, the IRS could seek to recharacterize the securities as debt instruments. In that event, U.S. Holders (as defined below) would be required to accrue into income original issue discount on the securities every year at a "comparable yield" determined at the time of issuance (as adjusted based on the difference, if any, between the actual and the projected amount of any contingent payments on the securities) and recognize all income and gain in respect of the securities as ordinary income. The risk that financial instruments providing for buffers, triggers or similar downside protection features, such as the securities, would be recharacterized as debt is greater than the risk of recharacterization for comparable financial instruments that do not have such features.

Non-U.S. Holders (as defined below) should note that we currently intend to withhold on any coupon paid to Non-U.S. Holders generally at a rate of 30%, or at a reduced rate specified by an applicable income tax treaty under an "other income" or similar provision, and will not be required to pay any additional amounts with respect to amounts withheld.

In 2007, the U.S. Treasury Department and the IRS released a notice requesting comments on the U.S. federal income tax treatment of "prepaid forward contracts" and similar instruments. While it is not clear whether the securities would be viewed as similar to the prepaid forward contracts described in the notice, it is possible that any 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. The notice focuses on a number of issues, the most relevant of which for holders of the securities are the character and timing of income or loss and the degree, if any, to which income realized by non-U.S. investors should be subject to withholding tax. Both U.S. and Non-U.S. Holders should consult their tax advisers regarding the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments, the issues presented by this notice and any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

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 price 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 price 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 price on any calculation day, and below its downside threshold price 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.

§

Investing in the securities exposes investors to risks associated with investments in securities with a concentration in the energy sector. The stocks included in the Energy Select Sector Index and that are generally tracked by the XLE Shares are stocks of companies whose primary business is directly associated with the energy sector, including the following sub-sectors: (i) oil, gas and consumable fuels and (ii) energy equipment and services. Because the value of the securities is linked to the performance of the XLE Shares, an investment in the securities exposes investors to risks associated with investments in securities with a concentration in the energy sector.

Energy companies develop and produce crude oil and natural gas and/or provide drilling and other energy resources production and distribution related services. Stock prices for these types of companies are mainly affected by the business, financial and operating condition of the particular company, as well as changes in prices for oil, gas and other types of fuels, which in turn largely depend on supply and demand for various energy products and services. Some of the factors that may influence supply and demand for energy products and services include: general economic conditions and growth rates, weather conditions, the cost of exploring for, producing and delivering oil and gas, technological advances affecting energy efficiency and energy consumption, the ability of the Organization of the Petroleum Exporting Countries (OPEC) to set and maintain production levels of oil, currency fluctuations, inflation, natural disasters, civil unrest, acts of sabotage or terrorism and other regional or global events. The profitability of energy companies may also be adversely affected by existing and future laws, regulations, government actions and other legal requirements relating to protection of the environment, health and safety matters and others that may increase the costs of conducting their business or may reduce or delay available business opportunities. Increased supply or weak demand for energy products and services, as well as various developments leading to higher costs of doing business or missed business opportunities, would adversely impact the performance of companies in the energy sector. The value of the securities may be subject to greater volatility and be more adversely affected by a single economic, political or regulatory occurrence affecting the energy sector or one of the sub-sectors of the energy sector than a different investment linked to securities of a more broadly diversified group of issuers.

§

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 Technology Select Sector Index and that are generally tracked by the XLK Shares 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 XLK Shares, 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 XLK Shares and, therefore, on the value of the securities.

§

Investing in the securities exposes investors to risks associated with investments in securities with a concentration in the industrial sector. The stocks included in the Industrial Select Sector Index and that are generally tracked by the XLI Shares are stocks of companies whose primary business is directly associated with the industrial sector. Stock prices for the types of companies included in this sector are affected by supply and demand both for their specific product or service and for industrial sector products in general. Other factors that will affect these companies include, but are not limited to, government regulation, world events and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities. Additionally, aerospace and defense companies, which represent a component segment of the industrial sector, can be significantly affected by government spending policies, because companies involved in this industry tend to rely to a significant extent on U.S. and foreign government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies may be heavily influenced by governmental defense spending policies, which are typically under pressure from efforts to control the U.S. (and other) government budgets. Additionally, stocks of transportation companies, which represent a component segment of the industrial sector, are often cyclical and can experience sharp price movements that may result from changes in the economy, fuel prices, labor agreements or insurance costs, among other factors.

§

The performance and market price of an underlying, particularly during periods of market volatility, may not correlate with the performance of the respective fund underlying index, the performance of the component securities of such fund underlying index or the net asset value per share of such underlying. Each underlying does not fully replicate the respective fund underlying index and may hold securities that are different than those included in the respective fund underlying index. In addition, the performance of an underlying will reflect additional transaction costs and fees that are not included in the calculation of the respective fund underlying index. All of these factors may lead to a lack of correlation between the performance of an underlying and the respective fund underlying index. In addition, corporate actions (such as mergers and spin-offs) with respect to the equity securities constituting an underlying may impact the variance between the performance of such underlying and the respective fund underlying index. Finally, because the shares of the underlyings are traded on an exchange and are subject to market supply and investor demand, the market price of one share of an underlying may differ from the net asset value per share of such underlying.

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

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

§

The antidilution adjustments the calculation agent is required to make do not cover every event that could affect the underlyings. MS & Co., as calculation agent, will adjust the adjustment factors for certain events affecting the underlyings. However, the calculation agent will not make an adjustment for every event that could affect the underlyings. If an event occurs that does not require the calculation agent to adjust an adjustment factor, the market

price of the securities may be materially and adversely affected. The determination by the calculation agent to adjust, or not to adjust, an adjustment factor may materially and adversely affect the value of the securities.

§

Adjustments to the underlyings or the fund underlying indices could adversely affect the value of the securities. The fund sponsor to each underlying (SSGA Funds Management, Inc.) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the relevant fund underlying index. Pursuant to its investment strategy or otherwise, the fund sponsor may add, delete or substitute the stocks composing an underlying. Any of these actions could adversely affect the price of such underlying and, consequently, the value of the securities. The fund underlying index sponsor of each fund underlying index may add, delete or substitute the stocks constituting such fund underlying index or make other methodological changes that could change the value of such fund underlying index. The fund underlying index sponsor of each fund underlying index may discontinue or suspend calculation or publication of such fund 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 fund underlying index and is permitted to consider indices that are calculated and published by the calculation agent or any of its affiliates. Any of these actions could adversely affect the value of a fund underlying index, and, consequently, the price of an underlying and the value of the securities.

§

Historical prices 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 price of the underlyings at any time, including on the final calculation day, because historical prices of the underlyings do not provide an indication of future performance of the underlyings.

Tax considerations

Due to the absence of statutory, judicial or administrative authorities that directly address the treatment of the securities or instruments that are similar to the securities for U.S. federal income tax purposes, no assurance can be given that the IRS or a court will agree with the tax treatment described herein. We intend to treat a security for U.S. federal income tax purposes as a single financial contract that provides for a coupon that will be treated as gross income to you at the time received or accrued in accordance with your regular method of tax accounting. In the opinion of our counsel, Davis Polk & Wardwell LLP, this treatment of the securities is reasonable under current law; however, our counsel has advised us that it is unable to conclude affirmatively that this treatment is more likely than not to be upheld, and that alternative treatments are possible. Moreover, our counsel's opinion is based on market conditions as of the date of this preliminary pricing supplement and is subject to confirmation on the pricing date.

Tax Consequences to U.S. Holders

Assuming the treatment of the securities as set forth above is respected and subject to the discussion in "United States Federal Taxation" in the accompanying product supplement for principal at risk securities, the following U.S. federal income tax consequences should result.

Tax Basis. A U.S. Holder's tax basis in the securities should equal the amount paid by the U.S. Holder to acquire the securities.

Tax Treatment of Coupon Payments. Any coupon payment on the securities should be taxable as ordinary income to a U.S. Holder at the time received or accrued, in accordance with the U.S. Holder's regular method of accounting for U.S. federal income tax purposes.

Sale, Exchange or Settlement of the Securities. Upon a sale, exchange or settlement of the securities, a U.S. Holder should recognize gain or loss equal to the difference between the amount realized on the sale, exchange or settlement and the U.S. Holder's tax basis in the securities sold, exchanged or settled. For this purpose, the amount realized does not include any coupon paid at settlement and may not include sale proceeds attributable to an accrued coupon, which may be treated in the same manner as a coupon payment. In general, any such gain or loss recognized should be short-term capital gain or loss if the U.S. Holder has held the securities for one year or less at the time of the sale, exchange or settlement, and should be long-term capital gain or loss otherwise. The ordinary income treatment of the coupon payments, in conjunction with the capital loss treatment of any loss recognized upon the sale, exchange or settlement of the securities, could result in adverse tax consequences to holders of the securities because the deductibility of capital losses is subject to limitations.

As discussed under "United States Federal Taxation- Possible Alternative Tax Treatments of an Investment in the Securities" in the accompanying product supplement for principal at risk securities, alternative U.S. federal income tax treatments of the securities are possible that, if applied, could materially and adversely affect the timing and character of income, gain or loss with respect to the securities.

Tax Consequences to Non-U.S. Holders

Although significant aspects of the tax treatment of each security are uncertain, we intend to withhold on any coupon paid to a Non-U.S. Holder generally at a rate of 30% or at a reduced rate specified by an applicable income tax treaty under an "other income" or similar provision. We will not be required to pay any additional amounts with respect to amounts withheld. In order to claim an exemption from, or a reduction in, the 30% withholding tax, a Non-U.S. Holder of the securities must comply with certification requirements to establish that it is not a U.S. person and is eligible for such an exemption or reduction under an applicable tax treaty. If you are a Non-U.S. Holder, you should consult your tax adviser regarding the tax treatment of the securities, including the possibility of obtaining a refund of any withholding tax and the certification requirement described above.

Section 871(m) Withholding Tax on Dividend Equivalents

As discussed in the accompanying product supplement for principal at risk securities, Section 871(m) of the Code and Treasury regulations promulgated thereunder ("Section 871(m)") generally impose a 30% (or a lower applicable treaty rate) withholding tax on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities (each, an "Underlying Security"). Subject to certain exceptions, Section 871(m) generally applies to securities that substantially replicate the economic performance of one or more Underlying Securities, as determined based on tests set forth in the applicable Treasury regulations (a "Specified Security"). However, pursuant to an IRS notice, Section 871(m) will not apply to securities issued before January 1, 2025 that do not have a delta of one with respect to any Underlying Security. Based on the terms of the securities and current market conditions, we expect that the securities 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 pricing supplement. Assuming that the securities do not have a delta of one with respect to any Underlying Security, our counsel is of the opinion that the securities should not be Specified Securities and, therefore, should not be subject to Section 871(m).

Our determination is not binding on the IRS, and the IRS may disagree with this determination. Section 871(m) is complex and its application may depend on your particular circumstances, including whether you enter into other transactions with respect to an Underlying Security. If Section 871(m) withholding is required, we will not be required to pay any additional amounts with respect to the amounts so withheld. You should consult your tax adviser regarding the potential application of Section 871(m) to the securities.

Both U.S. and non-U.S. investors considering an investment in the securities should read the discussion under "Risk Factors" in this document and the discussion under "United States Federal Taxation" in the accompanying product supplement for principal at risk securities and consult their tax advisers regarding all aspects of the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments, the issues presented by the 2007 notice described therein 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 principal at risk securities, insofar as they purport to describe provisions of U.S. federal income tax laws or legal conclusions with respect thereto, constitute the full opinion of Davis Polk & Wardwell LLP regarding the material U.S. federal tax consequences of an investment in the securities.

Additional considerations

Client accounts over which Morgan Stanley, Morgan Stanley Wealth Management or any of their respective subsidiaries have investment discretion are not permitted to purchase the securities, either directly or indirectly.
