Principal at Risk Securities Linked to the Lowest Performing of the Russell 2000^® Index, the Technology Select Sector SPDR^® Fund and the S&P 500^® Index due August 21, 2028

Fully and Unconditionally Guaranteed by Morgan Stanley

§ Linked to the lowest performing of the Russell 2000® Index, the Technology Select Sector SPDR® Fund and the S&P 500® Index (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. The securities will pay no interest, provide for a maturity payment amount that may be significantly less than the face amount, and may be zero, and 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. At maturity: § If the level of the lowest performing underlying has increased, investors will receive the face amount plus a positive return equal to 150% of the percentage increase in the level of the lowest performing underlying from its starting level, subject to a maximum return at maturity of at least 43% (to be determined on the pricing date) of the face amount. As a result of the maximum return, the maximum maturity payment amount will be at least $1,430 per security § If the level of the lowest performing underlying has decreased, but the lowest performing underlying has not decreased by more than the buffer amount of 30%, investors will receive the face amount plus an unleveraged positive return equal to the absolute value of the percentage decline in the level of the lowest performing underlying from the starting level to the ending level, which will effectively be limited to a positive return of 30% § If the level of the lowest performing underlying has decreased by more than the buffer amount, investors will have 1-to-1 downside exposure to the decrease in the level of the lowest performing underlying from its starting level in excess of the buffer amount § Investors may lose up to 70% of the face amount of the securities § The securities are for investors who seek an equity-based return and who are willing to risk their investment, risk exposure to the lowest performing underlying and forgo current income and upside above the maximum return in exchange for the participation rate, buffer and absolute return features that in each case apply to a limited range of performance of the lowest performing 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 $932.60 per security, or within $32.60 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.

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 $932.60, or within $32.60 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 maximum return, the participation rate and the threshold levels, 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 Russell 2000^® Index, the Technology Select Sector SPDR^® Fund and the S&P 500^® Index due August 21, 2028 (the "securities") may be appropriate for investors who:

§	Seek an alternative to direct exposure to the underlyings that enhances returns for a certain range of positive performance of the lowest performing underlying, subject to the maximum return

§	Seek to enhance returns and potentially outperform the lowest performing underlying by taking advantage of the participation rate, subject to the maximum return

§

Understand that any positive return based on the depreciation of the lowest performing underlying will be limited to 30%, and that any depreciation of the lowest performing underlying from the starting level to the ending level of more than the buffer amount will result in a loss, rather than a positive return, on the securities

§	Understand that the ending level of the lowest performing underlying may decrease by more than the buffer amount from its starting level, resulting in a loss of some or a significant portion of the initial investment

§	Desire to obtain a buffer against a specified level of negative performance in the lowest performing underlying

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

§	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 interest payments on the securities and dividends on securities included in the underlyings

§	Are willing to hold the securities to 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

§	Are unwilling to accept the risk that the ending level of the lowest performing underlying may decrease by more than the buffer amount from its starting level, resulting in a loss of some or a significant portion of the initial investment

§	Seek uncapped exposure to the upside performance of the lowest performing underlying

§	Seek full return of the face amount of the securities at maturity

§	Seek current income from their investments

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

§	Seek exposure to the lowest performing underlying but are unwilling to accept the risk/return trade-offs inherent in the maturity payment amount for the securities

§	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

§	Are unwilling to accept our credit risk

§	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 "Russell 2000^® Index Overview," "Technology Select Sector SPDR^® Fund Overview" and "S&P 500^® Index Overview" below.

Determining Maturity Payment Amount

At maturity, the maturity payment amount per $1,000 face amount of securities will be determined as follows:

Scenario Analysis and Examples of Maturity Payment Amount at Maturity

The following scenario analysis and examples are provided for illustrative purposes only and are hypothetical. They do not purport to be representative of every possible scenario concerning increases or decreases in the levels of the underlyings relative to their respective starting levels. We cannot predict the ending levels of the underlyings on the calculation day. You should not take the scenario analysis and these examples as an indication or assurance of the expected performance of the underlyings. The numbers appearing in the examples below may have been rounded for ease of analysis. Notwithstanding anything to the contrary in the accompanying product supplement for principal at risk securities, the amount you will receive per $1,000 face amount of securities at maturity will be the maturity payment amount, defined and calculated as provided in this document. The following scenario analysis and examples illustrate the maturity payment amount on a hypothetical offering of the securities, based on the following terms*:

Investment term:	4 years
Hypothetical starting level:	With respect to the RTY Index: 100
	With respect to the XLK Shares: $100
	With respect to the SPX Index: 100
Hypothetical threshold level:	With respect to the RTY Index, 70, which is 70% of its respective hypothetical starting level
	With respect to the XLK Shares, $70, which is 70% of its respective hypothetical starting level
	With respect to the SPX Index, 70, which is 70% of its respective hypothetical starting level
Buffer amount:	30%
Participation rate:	150%
Hypothetical maximum return:	43% of the face amount ($430 per security). The actual maximum return will be determined on the pricing date.

^* 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, threshold levels and maximum return 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.

Example 1 -Each underlying appreciates over the term of the securities, and investors receive a positive return, calculated based on the underlying return of the lowest performing underlying.

Ending level		RTY Index: 110
		XLK Shares: $140
		SPX Index: 150
Underlying return		RTY Index: (110 - 100) / 100 = 10% XLK Shares: ($140 - $100) / $100 = 40% SPX Index: (150 - 100) / 100 = 50%
Maturity payment amount	=	$1,000 plus the lesser of: (i) [$1,000 × underlying return of lowest performing underlying ×participation rate], and (ii) the maximum return of $430
	=	$1,000 plus the lesser of: (i) [$1,000 × 10% × 150%] (ii) $430
	=	$1,150

In example 1, the ending level of each of the RTY Index, the XLK Shares and the SPX Index is greater than its starting level. Therefore, investors receive at maturity the face amount plus the lesser of a positive return equal to 150% of the appreciation of the lowest performing underlying, which is the RTY Index in this example, and the maximum return of $430. Investors receive $1,150 per security at maturity.

Example 2 - Each underlying appreciates over the term of the securities, and investors receive a positive return, calculated based on the underlying return of the lowest performing underlying.

Ending level		RTY Index: 160
		XLK Shares: $180
		SPX Index: 150
Underlying return		RTY Index: (160 - 100) / 100 = 60% XLK Shares: ($180 - $100) / $100 = 80% SPX Index: (150 - 100) / 100 = 50%
Maturity payment amount	=	$1,000 plus the lesser of: (i) [$1,000 × underlying return of lowest performing underlying ×participation rate], and (ii) the maximum return of $430
	=	$1,000 plus the lesser of: (i) [$1,000 × 50% × 150%], and (ii) $430
	=	$1,430

In example 2, the ending level of each of the RTY Index, the XLK Shares and the SPX Index is greater than its starting level. Therefore, investors receive at maturity the face amount plus the lesser of a positive return equal to 150% of the appreciation of the lowest performing underlying, which is the SPX Index in this example, and the maximum return of $430. Investors receive $1,430 per security at maturity.

Example 3-One underlying appreciates, while the other two underlyings decline over the term of the securities but no underlying declines below the hypothetical starting level by more than the buffer amount, and investors receive a positive return, calculated based on the absolute underlying return of the lowest performing underlying.

Ending level		RTY Index: 130
		XLK Shares: $90
		SPX Index: 80
Underlying return		RTY Index: (130 - 100) / 100 = 30% XLK Shares: ($90 - $100) / $100 = -10% SPX Index: (80 - 100) / 100 = -20%
Maturity payment amount	=	$1,000 plus: [$1,000 × absolute underlying return of lowest performing underlying]
	=	$1,000 + [$1,000 × 20%]
	=	$1,200

In example 3, the ending level of the RTY Index is greater than its starting level, while the ending levels of the XLK Shares and the SPX Index are less than their respective starting levels, but are greater than or equal to their respective threshold levels. Therefore, investors receive at maturity the face amount plus a positive return equal to the absolute underlying return of the lowest performing underlying, which is the SPX Index in this example. Investors receive $1,200 per security at maturity.

Example 4 -Two underlyings appreciate while one underlying declines over the term of the securities, and the ending level of the lowest performing underlying is less than the hypothetical starting level by more than the buffer amount. Investors are therefore exposed to the decline in the level of the lowest performing underlying in excess of the buffer amount.

Ending level		RTY Index: 130
		XLK Shares: $105
		SPX Index: 30
Underlying return		RTY Index: (130 - 100) / 100 = 30% XLK Shares: ($105 - $100) / $100 = 5% SPX Index: (30 - 100) / 100 = -70%
Maturity payment amount	=	$1,000 + [$1,000 × underlying return of lowest performing underlying + buffer amount]
	=	$1,000 + [$1,000 ×-70% + 30%]
	=	$600

In example 4, the ending levels of the RTY Index and the XLK Shares are greater than their respective starting levels, while the ending level of the SPX Index has declined below its threshold level. Because the ending level of the SPX Index has declined by more than the buffer amount, investors are exposed to the negative performance of the SPX Index , which is the lowest performing underlying in this example, in excess of the buffer amount. Investors receive a maturity payment amount of $600.

Example 5-Each underlying declines below its respective threshold level, and investors are therefore exposed to the decline in the level of the lowest performing underlying in excess of the buffer amount.

Ending level		RTY Index: 30
		XLK Shares: $45
		SPX Index: 40
Underlying return		RTY Index: (30 - 100) / 100 = -70% XLK Shares: ($45 - $100) / $100 = -55% SPX Index: (40 - 100) / 100 = -60%
Maturity payment amount	=	$1,000 + [$1,000 × underlying return of lowest performing underlying + buffer amount]
	=	$1,000 + [$1,000 ×-70% + 30%]
	=	$600

In example 5, the ending level of each of the RTY Index, the XLK Shares and the SPX Index is less than its respective threshold level. Therefore, investors are exposed to the negative performance of the RTY Index, which is the lowest performing underlying in this example, in excess of the buffer amount. Investors receive a maturity payment amount of $600.

Because the maturity payment amount of the securities is based on the lowest performing underlying, a decline in any underlying below its respective threshold level will result in a loss of up to 70% of the face amount of your securities at maturity, even if the other underlyings have appreciated or have not declined as much.

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 pay interest, and you will receive less, and up to 70% less, than the face amount of your securities at maturity if the ending level of the lowest performing underlying is less than its respective threshold level. The terms of the securities differ from those of ordinary debt securities in that the securities do not pay interest or repay a fixed amount of the face amount of the securities. If the ending level of the lowest performing underlying is less than its threshold level, which is 70% of the starting level, the contingent absolute return feature will no longer be available and you will receive less, and up to 70% less, than the face amount of your securities at maturity. Investors may lose some or a significant portion of their investment in the securities.

§

The appreciation potential of the securities is limited by the maximum return. The appreciation potential of the securities is limited by the maximum return. Although the participation rate provides 150% exposure to any increase in the ending level over the starting level, because any positive return on the securities will be limited to the maximum return of at least 43% of the face amount for the securities, any increase in the ending level over the starting level by more than at least approximately 28.667% of the starting level, depending on the actual maximum return, will not further increase the return on the securities.

§

Any positive return based on the depreciation of the lowest performing underlying is effectively capped. Any positive return based on the depreciation of the lowest performing underlying will be capped at 30% because the contingent absolute return feature is operative only if the lowest performing underlying depreciates by no more than the buffer amount. Any depreciation of the lowest performing underlying by more than the buffer amount will result in a loss of some or a significant portion of the face amount and not a positive return.

§

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. or any other dealer may be willing to purchase or sell the securities in the secondary market, including the level, volatility (frequency and magnitude of changes in level) and dividend yield of the underlyings, interest and yield rates in the market, time remaining to maturity, geopolitical conditions and economic, financial, political, regulatory or judicial events that affect the underlyings or equities markets generally and which may affect the ending levels of the underlyings, the occurrence of certain events affecting the Fund that may or may not require an adjustment to the adjustment factor and any actual or anticipated changes in our credit ratings or credit spreads. Generally, the longer the time remaining to maturity, the more the market price of the securities will be affected by the other factors described above. The levels of the underlyings may be, and have recently been, volatile, and we can give you no assurance that the volatility will lessen. See "Russell 2000® Index Overview," "Technology Select Sector SPDR® Fund Overview" and "S&P 500® Index Overview" below. You may receive less, and possibly significantly less, than the face amount per security if you try to sell your securities prior to maturity.

§

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 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.

§

The amount payable on the securities is not linked to the values of the underlyings at any time other than the calculation day. The ending level of each underlying will be based on the closing level of such underlying on the calculation day, subject to postponement for non-trading days and certain market disruption events. Even if each underlying appreciates prior to the calculation day but the level of any underlying decreases by the calculation day, the maturity payment amount may be less, and may be significantly less, than it would have been had the maturity payment amount been linked to the levels of the underlyings prior to such decrease. Although the actual levels of the underlyings on the maturity date or at other times during the term of the securities may be higher than their respective ending levels, the maturity payment amount will be based solely on the closing levels on the calculation day.

§

Investing in the securities is not equivalent to investing in the underlyings or the stocks composing the Indices or the fund underlying index. Investing in the securities is not equivalent to investing in the underlyings or the stocks that constitute the Indices or the fund underlying index. Investors in the securities will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the stocks that constitute the Indices or the fund underlying index.

§

The rate we are willing to pay for securities of this type, maturity and issuance size is likely to be lower than the rate implied by our secondary market credit spreads and advantageous to us. Both the lower rate and the inclusion of costs associated with issuing, selling, structuring and hedging the 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 levels, the threshold levels and the ending levels and will calculate the amount of cash you receive at maturity. Moreover, certain determinations made by MS & Co., in its capacity as calculation agent, may require it to exercise discretion and make subjective judgments, such as with respect to the occurrence or non-occurrence of market disruption events and the selection of a successor index or calculation of an ending level in the event of a market disruption event, discontinuance of any of the underlyings or certain adjustments to the adjustment factor. These potentially subjective determinations may adversely affect the payout to you at maturity. 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," "-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 component stocks of the Indices or fund underlying index), including trading in the shares of the Fund or the stocks that constitute the Indices or the fund underlying index 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 calculation day approaches. Some of our affiliates also trade the shares of the Fund or the stocks that constitute the Indices or fund underlying index 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 the level at or above which such underlying must close on the calculation day so that investors do not suffer a loss on their initial investment in the securities (depending also on the performance of the other underlyings). Additionally, such hedging or trading activities during the term of the securities, including on the calculation day, could adversely affect the level of an underlying on the calculation day, and, accordingly, the amount of cash an investor will receive at maturity (depending also on the performance of the other underlyings).

§

The maturity date may be postponed if the calculation day is postponed. If the scheduled calculation day is not a trading day or if a market disruption event occurs on that day so that the 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 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. Please read the discussion under "Additional Information About the Securities-Tax considerations" in this document and the discussion under "United States Federal Taxation" in the accompanying product supplement for principal at risk securities (together, the "Tax Disclosure Sections") concerning the U.S. federal income tax consequences of an investment in the securities. As discussed in the Tax Disclosure Sections, there is a risk that the "constructive ownership" rule could apply, in which case all or a portion of any long-term capital gain recognized by a U.S. Holder could be recharacterized as ordinary income and an interest charge could be imposed. In addition, there is no direct legal authority regarding the proper U.S. federal tax treatment of the securities, and we do not plan to request a ruling from the Internal Revenue Service (the "IRS"). Consequently, significant aspects of the tax treatment of the securities are uncertain, and the IRS or a court might not agree with the tax treatment of a security as a single financial contract that is an "open transaction" for U.S. federal income tax purposes. If the IRS were successful in asserting an alternative treatment of the securities, the tax consequences of the ownership and disposition of the securities, including the timing and character of income recognized by U.S. Holders and the withholding tax consequences to Non-U.S. Holders, might be materially and adversely affected. Moreover, future legislation, Treasury regulations or IRS guidance could adversely affect the U.S. federal tax treatment of the securities, possibly retroactively.

Both U.S. and Non-U.S. Holders should consult their tax advisers regarding the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments, as well as any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Risks Relating to the 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 based 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 will negatively affect your return and will not be offset or mitigated by any positive performance by the other underlyings. If any underlying has declined to below its respective threshold level as of the calculation day, you will be exposed to the negative performance of the lowest performing underlying at maturity, even if the other underlyings have appreciated or have not declined as much, and you will lose a significant portion or all of your investment. 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 risk of sustaining a significant loss on your investment than if the securities were linked to just one underlying. The risk 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 decline to below its threshold level as of the calculation day, than if the securities were linked to only one underlying. Therefore it is more likely 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 the underlying index, 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. Such 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 with a concentration in the technology sector. The stocks included in the Technology Select Sector Index and that are generally tracked by the Technology Select Sector SPDR® Fund 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.

§

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

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

For all of the foregoing reasons, the performance of the Fund may not correlate with the performance of the fund underlying index, the performance of the component securities of the fund underlying index or the net asset value per

share of the Fund. Any of these events could materially and adversely affect the price of the shares of the Fund and, therefore, the value of the securities. Additionally, if market volatility or these events were to occur on the calculation day, the calculation agent would maintain discretion to determine whether such market volatility or events have caused a market disruption event to occur, and such determination may affect the payment at maturity of the securities. If the calculation agent determines that no market disruption event has taken place, the payment at maturity would be based on the published fund closing price per share of the Fund on the calculation day, even if the Fund's shares are underperforming the fund underlying index or the component securities of the fund underlying index and/or trading below the net asset value per share of the Fund.

§

Adjustments to the Indices could adversely affect the value of the securities. The publisher of any Index may add, delete or substitute the stocks constituting such Index or make other methodological changes that could change the value of such Index. The publisher of such Index may discontinue or suspend calculation or publication of such 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 Index and is permitted to consider indices that are calculated and published by the calculation agent or any of its affiliates. If the calculation agent determines that there is no appropriate successor Index, the maturity payment amount on the securities will be an amount based on the closing prices at maturity of the securities composing such Index at the time of such discontinuance, without rebalancing or substitution, computed by the calculation agent in accordance with the formula for calculating such Index last in effect prior to discontinuance of the Index.

§

Adjustments to the Fund or to the fund underlying index could adversely affect the value of the securities. The investment adviser to the XLK Shares, SSGA Funds Management, Inc. (the "Investment Adviser"), seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the fund underlying index. Pursuant to its investment strategy or otherwise, the Investment Adviser may add, delete or substitute the components securities of the Fund. Any of these actions could adversely affect the price of the shares of the Fund and, consequently, the value of the securities. In addition, the fund underlying index sponsor of the Fund is responsible for calculating and maintaining the fund underlying index. The fund underlying index sponsor may add, delete or substitute the stocks constituting the fund underlying index or make other methodological changes that could change the value of the shares of the Fund. The fund underlying index sponsor may also discontinue or suspend calculation or publication of a fund underlying index at any time. If this discontinuance or suspension occurs following the termination of the Fund, 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 values of the shares of the Fund and, consequently, the value of the securities.

§

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 calculation day, because historical levels of the underlyings do not provide an indication of future performance of the underlyings.

§

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

Tax considerations

Although there is uncertainty regarding the U.S. federal income tax consequences of an investment in the securities due to the lack of governing authority, in the opinion of our counsel, Davis Polk & Wardwell LLP, under current law, and based on current market conditions, it is reasonable to treat a security as a single financial contract that is an "open transaction" for U.S. federal income tax purposes. However, because our counsel's opinion is based in part on market conditions as of the date of this document, it is subject to confirmation on the pricing date.

Assuming this treatment of the securities 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 based on current law:

§	A U.S. Holder should not be required to recognize taxable income over the term of the securities prior to settlement, other than pursuant to a sale or exchange.

§

Upon sale, exchange or settlement of the securities, a U.S. Holder should recognize gain or loss equal to the difference between the amount realized and the U.S. Holder's tax basis in the securities. Subject to the discussion below concerning the potential application of the "constructive ownership" rule, such gain or loss should be long-term capital gain or loss if the investor has held the securities for more than one year, and short-term capital gain or loss otherwise.

Because the securities are linked to shares of an exchange-traded fund, although the matter is not clear, there is a risk that an investment in the securities will be treated as a "constructive ownership transaction" under Section 1260 of the Internal Revenue Code of 1986, as amended (the "Code"). If this treatment applies, all or a portion of any long-term capital gain of the U.S. Holder in respect of the securities could be recharacterized as ordinary income (in which case an interest charge will be imposed). As a result of certain features of the securities, including the leveraged upside payment and the fact that the securities are linked to indices in addition to an exchange-traded fund, it is unclear how to calculate the amount of gain that would be recharacterized if an investment in the securities were treated as a constructive ownership transaction. Due to the lack of governing authority, our counsel is unable to opine as to whether or how Section 1260 of the Code applies to the securities. U.S. investors should read the section entitled "United States Federal Taxation-Tax Consequences to U.S. Holders-Possible Application of Section 1260 of the Code" in the accompanying product supplement for principal at risk securities for additional information and consult their tax advisers regarding the potential application of the "constructive ownership" rule.

We do not plan to request a ruling from the Internal Revenue Service (the "IRS") regarding the treatment of the 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 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.

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, 2027 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 final 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 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 potential application of the constructive ownership rule, and any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

The discussion in the preceding paragraphs under "Tax considerations" and the discussion contained in the section entitled "United States Federal Taxation" in the accompanying product supplement for 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.
