Based on the Worst Performing of the S&P 500® Index and the Russell 2000® Index

Fully and Unconditionally Guaranteed by Morgan Stanley

Principal at Risk Securities

￭The securities are unsecured obligations of Morgan Stanley Finance LLC ("MSFL") and are fully and unconditionally guaranteed by Morgan Stanley. The securities have the terms described in the accompanying product supplement, index supplement and prospectus, as supplemented or modified by this document. The securities do not guarantee the repayment of principal.

￭Fixed coupon. The securities will pay a fixed coupon on each coupon payment date at the annual rate specified herein.

￭Payment at maturity. If the closing level of each underlier has remained greater than or equal to its downside threshold level on each trading day during the term of the securities, investors will receive, in addition to the fixed coupon with respect to the final interest period, the stated principal amount at maturity. If, however, the closing level of either underlier is less than its downside threshold level on any trading day during the term of the securities and the final level of either underlier is less than its initial level, although investors will still receive the fixed coupon with respect to the final interest period, investors will lose 1% for every 1% decline in the level of the worst performing underlier over the term of the securities. Under these circumstances, the payment at maturity will be less, and may be significantly less, than the stated principal amount and could be zero.

￭The value of the securities is based on the worst performing underlier. The fact that the securities are linked to more than one underlier does not provide any asset diversification benefits and instead means that a decline in the level of either underlier beyond its downside threshold level will adversely affect your return on the securities, even if the other underlier has appreciated or has not declined as much.

￭The securities are for investors who seek an opportunity to earn interest at a potentially above-market rate in exchange for the risk of losing some or all of their principal. You will not participate in any appreciation of either underlier. Investors in the securities must be willing to accept the risk of losing their entire initial investment based on the performance of either underlier. 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 underlying reference asset or assets.

Estimated Value of the Securities

The original issue price 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. Our estimate of the value of the securities as determined on the pricing date will be within the range specified on the cover hereof and will be set forth on the cover of 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 underliers. The estimated value of the securities is determined using our own pricing and valuation models, market inputs and assumptions relating to the underliers, instruments based on the underliers, 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, 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 underliers, 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, to the extent that MS & Co. may buy or sell the securities in the secondary market during the amortization period specified herein, absent changes in market conditions, including those related to the underliers, 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.

Hypothetical Examples

The following hypothetical examples illustrate how to calculate the payment at maturity. The following examples are for illustrative purposes only. You will receive a fixed coupon on each coupon payment date at the annual rate specified on the cover of this document, regardless of the performance of the underliers. The payment at maturity will be determined by reference to the closing level of each underlier throughout the term of the securities. The actual initial level and downside threshold level for each underlier will be determined on the strike date. All payments on the securities are subject to our credit risk. The numbers in the hypothetical examples below may have been rounded for ease of analysis. The below examples are based on the following terms:

Stated principal amount:	$1,000 per security
Hypothetical initial level:	With respect to the SPX Index, 100.00* With respect to the RTY Index, 100.00*
Hypothetical downside threshold level:	With respect to the SPX Index, 75.00, which is 75% of its hypothetical initial level With respect to the RTY Index, 75.00, which is 75% of its hypothetical initial level
Fixed coupon:	11.20% per annum (corresponding to approximately $9.333 per interest period per security). The actual fixed coupon will be an amount determined by the calculation agent based on the number of days in the applicable payment period, calculated on a 30/360 day-count basis. The hypothetical fixed coupon of $9.333 is used in these examples for ease of analysis.

*The hypothetical initial level of 100.00 for each underlier has been chosen for illustrative purposes only and does not represent the actual initial level of either underlier. Please see "Historical Information" below for historical data regarding the actual closing levels of the underliers.

How to calculate the payment at maturity:

If a trigger event HAS NOT occurred:

The hypothetical example below illustrates how to calculate the payment at maturity if a trigger event HAS NOT occurred on any trading day during the term of the securities.

Final Level		Payment at Maturity per Security (in addition to the fixed coupon of $9.333 with respect to the final interest period)
SPX Index	RTY Index
110.00 (greater than or equal to its downside threshold level)	115.00 (greater than or equal to its downside threshold level)	$1,000

The hypothetical example above assumes that the closing level of each underlier has remained greater than or equal to its downside threshold level on each trading day during the term of the securities. Therefore, investors receive at maturity, in addition to the fixed coupon with respect to the final interest period, the stated principal amount. Investors do not participate in any appreciation of either underlier.

If a trigger event HAS occurred:

The hypothetical examples below illustrate how to calculate the payment at maturity, assuming the closing level of at least one underlier has been less than its downside threshold level on one or more trading days during the term of the securities, meaning that a trigger event HAS occurred with respect to the securities.

	Final Level		Payment at Maturity per Security (in addition to the fixed coupon of $9.333 with respect to the final interest period)
	SPX Index	RTY Index
Example #1	105.00 (greater than or equal to its downside threshold level)	115.00 (greater than or equal to its downside threshold level)	$1,000
Example #2	85.00 (greater than or equal to its downside threshold level)	110.00 (greater than or equal to its downside threshold level)	($1,000 × performance factor of the worst performing underlier, subject to a maximum payment at maturity of $1,000) = $1,000 × (85.00 / 100.00) = $850.00
Example #3	50.00 (less than its downside threshold level)	20.00 (less than its downside threshold level)	$1,000 × performance factor of the worst performing underlier, subject to a maximum payment at maturity of $1,000 = $1,000 × (20.00 / 100.00) = $200.00

In example #1, the final level of each underlier is greater than or equal to its downside threshold level. Although a trigger event has previously occurred, because the worst performing underlier has not depreciated from its initial level to its final level, investors do not suffer a loss on their initial investment and receive at maturity, in addition to the fixed coupon with respect to the final interest period, the stated principal amount. Investors do not participate in any appreciation of either underlier.

In example #2, because a trigger event has previously occurred and the worst performing underlier has depreciated from its initial level to its final level, investors receive at maturity, in addition to the fixed coupon with respect to the final interest period, a payment that reflects a loss of 1% of principal for each 1% decline in the level of the worst performing underlier, even though the final level of each underlier is greater than or equal to its downside threshold level.

In example #3, because a trigger event has previously occurred and the worst performing underlier has depreciated from its initial level to its final level, investors receive at maturity, in addition to the fixed coupon with respect to the final interest period, a payment that reflects a loss of 1% of principal for each 1% decline in the level of the worst performing underlier.

Fixed Income Securities with Daily Trigger Monitoring Principal at Risk Securities

If a trigger event occurs on any trading day during the term of the securities, you will be exposed to the negative performance of the worst performing underlier at maturity. Under these circumstances, if the final level of either underlier is less than its initial level, your payment at maturity will be less, and may be significantly less, than the stated principal amount of the securities 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 and prospectus. We also urge you to consult with 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 any principal. The terms of the securities differ from those of ordinary debt securities in that they do not guarantee the repayment of any principal. If the closing level of either underlier is less than its downside threshold level on any trading day during the term of the securities, you will be exposed to the negative performance of the worst performing underlier at maturity. Under these circumstances, if the final level of either underlier is less than its downside threshold level, the payout at maturity will be, in addition to the fixed coupon with respect to the final interest period, an amount in cash that is less, and may be significantly less, than the stated principal amount of each security, and you will lose an amount proportionate to the full decline in the level of the worst performing underlier over the term of the securities. There is no minimum payment at maturity on the securities, and, accordingly, you could lose your entire initial investment in the securities.

￭Investors will not participate in any appreciation in the value of either underlier. Regardless of whether or not a trigger event occurs on any trading day during the term of the securities, investors will not participate in any appreciation in the value of either underlier from the strike date to the observation date, and the return on the securities will be limited to the fixed coupons that are paid on the coupon payment dates.

￭The market price of the securities may 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 value of each underlier at any time will affect the value of the securities more than any other single factor. Other factors that may influence the value of the securities include:

othe volatility (frequency and magnitude of changes in value) of the underliers;

ointerest and yield rates in the market;

othe level of correlation between the underliers;

ogeopolitical conditions and economic, financial, political, regulatory or judicial events that affect the underliers or equity markets generally;

othe availability of comparable instruments;

othe composition of each underlier and changes in the component securities of each underlier;

othe time remaining until the securities mature; and

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

Some or all of these factors will influence the price that you will receive if you sell your securities prior to maturity. 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. For example, you may have to sell your securities at a substantial discount from the stated principal amount if, at the time of sale, the closing level of either underlier is at, below or not sufficiently above its downside threshold level, or if market interest rates rise.

You can review the historical closing levels of the underliers in the section of this document called "Historical Information." You cannot predict the future performance of an underlier based on its historical performance. The values of the underliers may be, and have recently been, volatile, and we can give you no assurance that the volatility will lessen. There can be no assurance that the closing level of each underlier will be greater than or equal to its downside threshold level on each trading day during the term of the securities so that you are not exposed to the negative performance of the worst performing underlier at 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, and, therefore, you are subject to our credit risk. The securities are not guaranteed by any other entity. 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

Page 7

Morgan Stanley Finance LLC

Fixed Income Securities with Daily Trigger Monitoring Principal at Risk Securities

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 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 original issue price reduce the economic terms of the securities, cause the estimated value of the securities to be less than the original issue price and will adversely affect secondary market prices. Assuming no change in market conditions or any other relevant factors, the prices, if any, at which dealers, including MS & Co., may be willing to purchase the securities in secondary market transactions will likely be significantly lower than the original issue price, because secondary market prices will exclude the issuing, selling, structuring and hedging-related costs that are included in the original issue price and borne by you and because the secondary market prices will reflect our secondary market credit spreads and the bid-offer spread that any dealer would charge in a secondary market transaction of this type as well as other factors.

The inclusion of the costs of issuing, selling, structuring and hedging the securities in the original issue price 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, to the extent that MS & Co. may buy or sell the securities in the secondary market during the amortization period specified herein, absent changes in market conditions, including those related to the underliers, 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 of the securities may 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. 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. When it does make a market, it will generally do so for transactions of routine secondary market size at prices based on its estimate of the current value of the securities, taking into account its bid/offer spread, our credit spreads, market volatility, the notional size of the proposed sale, the cost of unwinding any related hedging positions, the time remaining to maturity and the likelihood that it will be able to resell the 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. is willing to transact. If, at any time, MS & Co. 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.

￭As discussed in more detail in the accompanying product supplement, investing in the securities is not equivalent to investing in the underlier(s).

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

Risks Relating to the Underlier(s)

￭Because your return on the securities will depend upon the performance of the underlier(s), the securities are subject to the following risk(s), as discussed in more detail in the accompanying product supplement.

oYou are exposed to the price risk of each underlier.

oBecause the securities are linked to the performance of the worst performing underlier, you are exposed to a greater risk of sustaining a significant loss on your investment than if the securities were linked to just one underlier.

oAdjustments to an underlying index could adversely affect the value of the securities.

￭The securities are subject to risks associated with small-capitalization companies. The Russell 2000® Index consists of stocks issued by companies with relatively small market capitalization. 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 indices 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.

Risks Relating to Conflicts of Interest

In engaging in certain activities described below and as discussed in more detail in the accompanying product supplement, our affiliates may take actions that may adversely affect the value of and your return on the securities, and in so doing they will have no obligation to consider your interests as an investor in the securities.

￭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 make any determinations necessary to calculate any payment(s) on the securities. Moreover, certain determinations made by MS & Co., in its capacity as calculation agent, may require it to exercise discretion and make subjective judgments, which may adversely affect your return on the 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.

United States federal income tax considerations:	You should review carefully the section in the accompanying product supplement entitled "United States Federal Income Tax Considerations." The following discussion, when read in combination with the section entitled "United States Federal Income Tax Considerations" in the accompanying product supplement, constitutes the full opinion of our counsel, Davis Polk & Wardwell LLP, regarding the material U.S. federal income tax consequences of owning and disposing of the securities. Generally, this discussion assumes that you purchased the securities for cash in the original issuance at the stated issue price and does not address other circumstances specific to you, including consequences that may arise due to any other investments relating to an underlier. You should consult your tax adviser regarding the effect any such circumstances may have on the U.S. federal income tax consequences of your ownership of a security. Due to the lack of direct legal authority, there is substantial uncertainty regarding the U.S. federal income tax consequences of an investment in the securities. In the opinion of our counsel, which is based on current market conditions, it is reasonable to treat a security for U.S. federal income tax purposes as a put option (the "Put Option") written by you with respect to the underlier(s), secured by a cash deposit equal to the stated principal amount of the security (the "Deposit"), as described in the section entitled "United States Federal Income Tax Considerations-Tax Consequences to U.S. Holders-Securities Treated as Put Options and Deposits" in the accompanying product supplement. There is uncertainty regarding this treatment, and the IRS or a court might not agree with it. Moreover, because this treatment of the securities and our counsel's opinion are based on market conditions as of the date of this preliminary pricing supplement, each is subject to confirmation on the pricing date. A different tax treatment could be adverse to you. Under the treatment of a security as a Put Option and a Deposit, a portion of each coupon made with respect to the securities will be attributable to interest on the Deposit, and the remainder will represent premium attributable to your grant of the Put Option ("Put Premium"). Amounts treated as interest on the Deposit should be taxed as ordinary interest income, while the Put Premium should not be taken into account until retirement (including an early redemption) or an earlier taxable disposition. Pursuant to this treatment, set forth below are the portions of each coupon that we have determined should be treated as attributable to interest on the Deposit and to Put Premium: Coupon Rate per Annum(1) Interest on Deposit per Annum(1) Put Premium per Annum(1) % % % % % % (1) To be provided in the final pricing supplement We do not plan to request a ruling from the IRS regarding the treatment of the securities. An alternative characterization of the securities could materially and adversely affect the tax consequences of ownership and disposition of the securities, including the timing and character of income recognized. In particular, there is a risk that a security could be characterized as a single debt instrument for U.S. federal income tax purposes, in which case the tax consequences of an investment in the securities could be different from those described herein and possibly adverse to certain investors. In addition, the U.S. Treasury Department and the IRS have requested comments on various issues regarding the U.S. federal income tax treatment of "prepaid forward contracts" and similar financial instruments and have indicated that such transactions may be the subject of future regulations or other guidance. Furthermore, members of Congress have proposed legislative changes to the tax treatment of derivative contracts. Any legislation, Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, possibly with retroactive effect. Non-U.S. Holders. Assuming the treatment of a security as a Put Option and a Deposit is respected, subject to the discussions below and in the section of the accompanying product supplement entitled "United States Federal Tax Considerations," if you are a Non-U.S. Holder of the securities, under current law you generally should not be subject to U.S. federal withholding or income tax in respect of any amount paid to you with respect to the securities, provided that (i) income in respect of the securities is not effectively connected with your conduct of a trade or business in the United States, and (ii) you comply with the applicable certification requirements. As discussed under "United States Federal Income Tax Considerations-Tax Consequences to Non-U.S. Holders-Dividend Equivalents under Section 871(m) of the Code" in the accompanying product supplement, Section 871(m) of the Internal Revenue Code and Treasury regulations promulgated

	thereunder ("Section 871(m)") generally impose a 30% withholding tax on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities. The Treasury regulations, as modified by an IRS notice, exempt financial instruments issued prior to January 1, 2027 that do not have a "delta" of one. Based on certain determinations made by us, we expect that Section 871(m) will not apply to the securities with regard to Non-U.S. Holders. Our determination is not binding on the IRS, and the IRS may disagree with this determination. If necessary, further information regarding the potential application of Section 871(m) will be provided in the final pricing supplement for the securities. While we currently do not intend to withhold on payments on the securities to Non-U.S. Holders (subject to compliance with the applicable certification requirements and the discussion in the section entitled "FATCA" in the accompanying product supplement), in light of the uncertain treatment of the securities other persons having withholding responsibility in respect of the securities may treat some or all of each coupon payment on a security as subject to withholding tax at a rate of 30%. Moreover, it is possible that in the future we may determine that we should withhold at a rate of 30% on coupon payments on the securities. We will not be required to pay any additional amounts with respect to U.S. federal withholding taxes. You should consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments, as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.
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.
