Market Linked Securities—Auto-Callable with Leveraged Upside Participation with Contingent Absolute Return and Contingent Downside

Principal at Risk Securities Linked to the Lowest Performing of the Common Stock of Microsoft Corporation, the Common Stock of Broadcom Inc., the Class A Common Stock of Alphabet Inc. and the Class A Common Stock of Meta Platforms, Inc. due November 2, 2028

Fully and Unconditionally Guaranteed by Morgan Stanley

￭Linked to the lowest performing of the common stock of Microsoft Corporation, the common stock of Broadcom Inc., the class A common stock of Alphabet Inc. and the class A common stock of Meta Platforms, Inc.(each referred to as an “underlying stock”) ￭The securities 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 pay interest, do not guarantee the repayment of principal and are subject to potential automatic call 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 and prospectus, as supplemented or modified by this document. ￭Automatic Call. The securities will be automatically called if the stock closing price of the lowest performing underlying stock on the call date is greater than or equal to its call price for a call payment equal to the face amount plus the call premium of 43.00% of the face amount. No further payments will be made on the securities once they have been called. The call price for each underlying is equal to 90% of its starting price. ￭Maturity Payment Amount. If the securities are not automatically called prior to maturity, you will receive at maturity a cash payment per security as follows: ￭If the ending price of the lowest performing underlying stock is greater than its starting price, you will receive a maturity payment amount equal to the face amount plus a positive return equal to 232% of the percentage increase in the price of the lowest performing underlying stock from its starting price. ￭If the ending price of the lowest performing underlying stock is equal to or less than its starting price, but greater than or equal to 60% of its starting price, which we refer to as the threshold price, you will receive a maturity payment amount of $1,000 plus an unleveraged positive return equal to the absolute value of the percentage decline in the price of the lowest performing underlying stock from its starting price to its ending price, which will effectively be limited to a positive return of 40% per $1,000 security. ￭If the ending price of the lowest performing underlying stock is less than its threshold price, you will have full downside exposure to the decrease in the price of the lowest performing underlying stock from its starting price, and you will lose more than 40%, and possibly all, of your initial investment. ￭The maturity payment amount may be significantly less than the face amount, and you could lose your entire investment. ￭The securities are for investors who are willing to risk their principal and forgo current income in exchange for the possibility of receiving a call payment greater than the face amount if the stock closing price of each underlying stock is greater than or equal to its call price on the call date or maturity payment amount greater than the face amount if the ending price of each underlying stock is greater than its starting price on the calculation day, in addition to the absolute return feature that applies to only a limited range of performance of the lowest performing underlying stock. ￭Because all payments on the securities are based on the lowest performing of the underlying stocks, a decline in price of more than 40% by any underlying stock will result in a loss on your investment, even if the other underlying stocks have appreciated or have not declined as much. ￭If the securities are automatically called prior to maturity, investors will not participate in any appreciation of any underlying stock. ￭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, the underlying stocks.

The current estimated value of the securities is $918.70. The estimated value of the securities is determined using our own pricing and valuation models, market inputs and assumptions relating to the underlying stocks, instruments based on the underlying stocks, 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 10. 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 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.

Principal at Risk Securities Linked to the Lowest Performing of the Common Stock of Microsoft Corporation, the Common Stock of Broadcom Inc., the Class A Common Stock of Alphabet Inc. and the Class A Common Stock of Meta Platforms, Inc. due November 2, 2028

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 is less than $1,000 per security. We estimate that the value of each security on the pricing date is $918.70. 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 underlying stocks. The estimated value of the securities is determined using our own pricing and valuation models, market inputs and assumptions relating to the underlying stocks, instruments based on the underlying stocks, 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 call payment amount, the call prices and the 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 underlying stocks, 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 3 months following the issue date, to the extent that MS & Co. may buy or sell the securities in the secondary market, absent changes in market conditions, including those related to the underlying stocks, 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 Common Stock of Microsoft Corporation, the Common Stock of Broadcom Inc., the Class A Common Stock of Alphabet Inc. and the Class A Common Stock of Meta Platforms, Inc. due November 2, 2028 (the “securities”) may be appropriate for investors who: ￭believe that the stock closing price of each underlying stock will be greater than or equal to its call price on the call date; ￭seek the potential for a fixed return if the stock closing price of each underlying stock has appreciated at all as of the call date in lieu of 232% leveraged participation in any potential appreciation of any underlying stock; ￭if the securities are not automatically called prior to maturity, seek exposure to 232% of the positive performance of the lowest performing underlying stock if the ending price of the lowest performing underlying stock is greater than its starting price; ￭understand that any positive return based on the depreciation of the lowest performing underlying stock will be limited to 40%, and that if the stock closing price of any underlying stock on the calculation day has declined by more than 40% from its starting price, they will lose more than 40%, and possibly all, of the face amount of their securities at maturity; ￭understand that the term of the securities may be as short as approximately one year, and that if the securities are automatically called, no further payments will be made on the securities once they have been called; ￭understand that the return on the securities will depend solely on the performance of the underlying stock that is the lowest performing underlying stock on the call date or, if the securities are not automatically called prior to maturity, on the calculation day, and that they will not benefit in any way from the performance of the better performing underlying stocks on either date; ￭understand that the securities are riskier than alternative investments linked to only one of the underlying stocks or linked to a basket composed of each underlying stock; ￭understand and are willing to accept the full downside risks of each underlying stock; ￭are willing to forgo interest payments on the securities and dividends on the underlying stocks; 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; ￭believe that the stock closing price of each underlying stock will be less than its call price on the call date or its starting price on the calculation day; ￭seek a security with a fixed term; ￭are unwilling to accept the risk that, if the securities are not automatically called prior to maturity, the stock closing price of the lowest performing underlying stock on the calculation day may decline by more than 40% from its starting price to its ending price, in which case they will lose more than 40%, and possibly all, of the face amount of their securities at maturity; ￭seek current income; ￭are unwilling to accept the risk of exposure to the underlying stocks; ￭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 underlying stocks, please see the sections titled “Microsoft Corporation Overview,” “Broadcom Inc. Overview,” “Alphabet Inc. Overview” and “Meta Platforms, Inc. Overview” below.

Scenario Analysis and Examples of Hypothetical Payments on the Securities

The following scenario analysis and examples are provided for illustrative purposes only and are hypothetical. Whether the securities are automatically called prior to maturity will be determined by reference to the stock closing price of each underlying stock on the call date, and the maturity payment amount will be determined by reference to the stock closing price of each underlying stock on the calculation day. The actual starting prices, call prices and threshold prices are set forth under “Final Terms” above. Some numbers appearing in the examples below have been rounded for ease of analysis. All payments on the securities are subject to our credit risk. The below examples are based on the following terms*:

Investment term: | Approximately 3 years
Call payment: | The call payment will be an amount in cash per face amount (corresponding to a return of 43.00% of the face amount), as follows: ●Call date: $1,430 No further payments will be made on the securities once they have been called.
Hypothetical starting price: | With respect to the MSFT Stock: $100.00 With respect to the AVGO Stock: $100.00 With respect to the GOOGL Stock: $100.00 With respect to the META Stock: $100.00
Hypothetical call price: | With respect to the MSFT Stock: $90.00, which is 90% of the hypothetical starting price With respect to the AVGO Stock: $90.00, which is 90% of the hypothetical starting price With respect to the GOOGL Stock: $90.00, which is 90% of the hypothetical starting price With respect to the META Stock: $90.00, which is 90% of the hypothetical starting price
Hypothetical threshold price: | With respect to the MSFT Stock: $60.00, which is 60% of the hypothetical starting price With respect to the AVGO Stock: $60.00, which is 60% of the hypothetical starting price With respect to the GOOGL Stock: $60.00, which is 60% of the hypothetical starting price With respect to the META Stock: $60.00, which is 60% of the hypothetical starting price
Participation rate: | 232%

* The hypothetical starting price of $100.00 for the underlying stocks has been chosen for illustrative purposes only and does not represent the actual starting price of any underlying stock. The actual starting prices, call prices and threshold prices are set forth under “Final Terms” above. For historical data regarding the actual closing prices of the underlying stocks, see the historical information set forth herein.

Automatic Call:

Example 1 — The securities are automatically called following the call date.

Date | MSFT Stock Closing Price | AVGO Stock Closing Price | GOOGL Stock Closing Price | META Stock Closing Price | Payment (per Security)
Call date | $150.00 (greater than or equal to the call price) | $125.00 (greater than or equal to the call price) | $115.00 (greater than or equal to the call price) | $110.00 (greater than or equal to the call price) | $1,430

In this example, on the call date, the stock closing price of each underlying stock is greater than or equal to its call price. Therefore, the securities are automatically called on the call settlement date. Investors will receive a payment of $1,430 per security on the call settlement date. No further payments will be made on the securities once they have been called, and investors do not participate in the appreciation in any underlying stock.

Principal at Risk Securities Linked to the Lowest Performing of the Common Stock of Microsoft Corporation, the Common Stock of Broadcom Inc., the Class A Common Stock of Alphabet Inc. and the Class A Common Stock of Meta Platforms, Inc. due November 2, 2028

How to calculate the payment investors will receive at maturity:

In the following examples, the stock closing price of one or more of the underlying stocks is less than its call price on the call date, and, consequently, the securities are not automatically called prior to maturity.

| MSFT Stock Closing Price | AVGO Stock Closing Price | GOOGL Stock Closing Price | META Stock Closing Price | Maturity Payment Amount (per Security)
Example 1 | $120.00 (greater than the starting price) | $110.00 (greater than the starting price) | $115.00 (greater than the starting price) | $125.00 (greater than the starting price) | $1,000 + ($1,000 × stock return of the lowest performing underlying stock × participation rate) = $1,000 + ($1,000 × 10% × 232%) = $1,232
Example 2 | $150.00 (greater than the starting price) | $90.00 (less than the starting price but greater than or equal to the threshold price) | $130.00 (greater than the starting price) | $120.00 (greater than the starting price) | $1,000 + ($1,000 × absolute stock return of lowest performing underlying stock) = $1,000 + ($1,000 × 10%) = $1,100
Example 3 | $40.00 (less than the threshold price) | $105.00 (greater than the starting price) | $120.00 (greater than the starting price) | $110.00 (greater than the starting price) | $1,000 + ($1,000 × stock return of the lowest performing underlying stock) = $1,000 + ($1,000 × -60%) = $400
Example 4 | $35.00 (less than the threshold price) | $20.00 (less than the threshold price) | $40.00 (less than the threshold price) | $45.00 (less than the threshold price) | $1,000 + ($1,000 × -80%) = $200

In example 1, the ending price of each underlying stock is greater than its starting price. Therefore, investors receive at maturity the face amount plus a return reflecting 232% of the appreciation of the lowest performing underlying stock. Investors receive $1,232 per security at maturity.

In example 2, the ending prices of three of the underlying stocks are greater than their starting prices, but the ending price of the other underlying stock is less than the starting price. Because the ending price of the lowest performing underlying stock is less than its starting price but greater than or equal to its threshold price, investors receive a maturity payment amount equal to the face amount plus an unleveraged return reflecting the absolute value of the 10% decline in the lowest performing underlying stock, representing a 10% return over the 3-year term of the securities.

In example 3, the ending prices of three of the underlying stocks are greater than their starting prices, but the ending price of the other underlying stock is less than its threshold price. Therefore, investors are fully exposed to the negative performance of the lowest performing underlying stock and will receive a maturity payment amount that is less than the face amount of the securities, even though the value of the other three underlying stocks have increased from their starting prices. The maturity payment amount is $400 per security, representing a loss of 60% on your investment over the 3-year term of the securities.

In example 4, the ending price of each underlying stock is less than its threshold price. Therefore, investors are fully exposed to the negative performance of the lowest performing underlying stock and will receive a maturity payment amount that is less than the face amount of the securities. The maturity payment amount is $200 per security, representing a loss of 80% on your investment over the 3-year term of the securities.

If the securities are not automatically called prior to maturity and the ending price of ANY underlying stock is less than its threshold price on the calculation day, you will be fully exposed to the decline in the stock closing price of the lowest performing underlying stock. You may lose more than 40%, and possibly all, of your investment.

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 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 or 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 pay interest or guarantee the return of the face amount of your securities at maturity. If the securities have not been automatically called and if the ending price of any underlying stock is less than its threshold price, the contingent absolute return feature will no longer be available and you will lose more than 40%, and possibly all, of your investment.

￭Any positive return based on the depreciation of the lowest performing underlying stock is effectively capped. Any positive return based on the depreciation of the lowest performing underlying stock will be capped at 40% because the contingent absolute return feature is operative only if the ending price of the lowest performing underlying stock is greater than or equal to its threshold price. Any depreciation of the lowest performing underlying stock beyond its threshold price will result in a loss of more than 40%, and possibly all, of your investment.

￭If the securities are automatically called prior to maturity, the appreciation potential of the securities is limited by the fixed call payment specified for the call date. If the stock closing price of each underlying stock is greater than or equal to its call price on the call date, the securities will be automatically called. In this scenario, the appreciation potential of the securities is limited to the fixed call payment specified on the call date, and no further payments will be made on the securities once they have been called. In addition, if the securities are automatically called prior to maturity, you will not participate in any appreciation of any underlying stock, which could be significant. Moreover, the fixed call payment may be less than the maturity payment amount you would receive for the same level of appreciation of the lowest performing underlying stock had the securities not been automatically called and instead remained outstanding until maturity.

￭The market price will be influenced by many unpredictable factors. Several factors, many of which are beyond our control, will influence the value of the securities in the secondary market and the price at which MS & Co. may be willing to purchase or sell the securities in the secondary market. We expect that generally the level of interest rates available in the market and the value of each underlying stock on any day, including in relation to its starting price, call price and 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 underlying stocks,

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

o dividend rates on the underlying stocks,

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 underlying stocks that may or may not require an adjustment to the adjustment factors, 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. For example, you may have to sell your securities at a substantial discount from the face amount of $1,000 per security if the stock closing price of any underlying stock at the time of sale is near or below its threshold price or if market interest rates rise.

You cannot predict the future performance of any underlying stock based on historical performance. If the securities are not automatically called prior to maturity and the ending price of any underlying stock is less than its threshold price, you will be exposed to any decline in the stock closing price of the lowest performing underlying stock in excess of 40%. See “Microsoft Corporation Overview,” “Broadcom Inc. Overview,” “Alphabet Inc. Overview” and “Meta Platforms, Inc. 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 an automatic call 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 underlying stocks. Investing in the securities is not equivalent to investing in the underlying stocks. 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 underlying stocks. As a result, any return on the securities will not reflect the return you would realize if you actually owned shares of the underlying stocks and received the dividends paid or distributions made on them.

￭Reinvestment risk. The term of your investment in the securities may be shortened due to the automatic call feature of the securities. If the securities are automatically called prior to maturity, you will receive no further payments on the securities and may be forced to invest in a lower interest rate environment and may not be able to reinvest at comparable terms or returns. However, under no circumstances will the securities be called at any point other than the specified call settlement date.

￭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 3 months following the issue date, to the extent that MS & Co. may buy or sell the securities in the secondary market, absent changes in market conditions, including those related to the underlying stocks, 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 call prices, the threshold prices, the ending prices, whether the securities will be called on the call settlement date and will calculate the amount of cash you receive at maturity if the securities are not automatically called prior to 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 certain adjustments to the adjustment factors. 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— Certain Terms for Securities Linked to an Underlying Stock— Market Disruption Events,” “—Adjustment Events,” “—Consequences of a Market Disruption Event; Postponement of a Calculation Day,” “—Alternate Exchange Calculation in Case of an Event of Default” and related definitions 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 underlying stocks), including trading in the underlying stocks as well as in other instruments related to the underlying stocks. 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 underlying stocks and other financial instruments related to the underlying stocks 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 stock, and, therefore, could increase (i) the price at or above which such underlying stock must close on the call date so that the securities are automatically called for the call payment (depending also on the performance of the other underlying stocks) and (ii) the threshold price for such underlying stock, which is the price at or above which such underlying stock must close on the calculation day so that you do not suffer a loss on your initial investment in the securities (depending also on the performance of the other underlying stocks). Additionally, such hedging or trading activities during the term of the securities could potentially affect the value of any underlying stock on the call date, and, accordingly, whether we call the securities prior to maturity and the amount of cash you will receive at maturity, if any.

￭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 underlying stocks 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. 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 Underlying Stocks

￭You are exposed to the price risk of each underlying stock. Your return on the securities is not linked to a basket consisting of the underlying stocks. Rather, it will be contingent upon the independent performance of each underlying stock. Unlike an instrument with a return linked to a basket of underlying stock 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 stock. Poor performance by any underlying stock 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 underlying stocks. To receive the call payment, the stock closing price of each underlying stock must be greater than or equal to its call price on the call date. In addition, if the securities have not been called prior to maturity and the value of any underlying stock has declined to below its threshold price as of the calculation day, you will be fully exposed to the decline in the lowest performing underlying stock from its starting price, even if the other underlying stocks have appreciated or have not declined as much. Under this scenario, the value of any such maturity payment amount will be less than 60% of the face amount of your securities and could be zero. Accordingly, your investment is subject to the price risk of each underlying stock.

￭Because the securities are linked to the performance of the lowest performing underlying stock, you are exposed to greater risk of sustaining a loss on your investment than if the securities were linked to just one underlying stock. The risk that you will suffer a 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 stock. With four underlying stocks, it is more likely that the ending price of any underlying stock will decline to below 40% of its starting price than if the securities were linked to only one underlying stock. Therefore, it is more likely that you will suffer a loss on your investment. In addition, because the value of each underlying stock must be greater than or equal to its starting price on the call date in order for the securities to be called prior to maturity, the securities are less likely to be called on the call settlement date than if the securities were linked to just one underlying stock.

￭No affiliation with Microsoft Corporation, Broadcom Inc., Alphabet Inc. or Meta Platforms, Inc. Microsoft Corporation, Broadcom Inc., Alphabet Inc. or Meta Platforms, Inc. are not affiliates of ours, are not involved with this offering in any way, and have no obligation to consider your interests in taking any corporate actions that might affect the value of the securities. We have not made any due diligence inquiry with respect to Microsoft Corporation, Broadcom Inc., Alphabet Inc. or Meta Platforms, Inc. in connection with this offering.

￭We may engage in business with or involving Microsoft Corporation, Broadcom Inc., Alphabet Inc. or Meta Platforms, Inc. without regard to your interests. We or our affiliates may presently or from time to time engage in business with Microsoft Corporation, Broadcom Inc., Alphabet Inc. or Meta Platforms, Inc. without regard to your interests and thus may acquire non-public information about Microsoft Corporation, Broadcom Inc., Alphabet Inc. or Meta Platforms, Inc. Neither we nor any of our affiliates undertakes to disclose any such information to you. In addition, we or our affiliates from time to time have published and in the future may publish research reports with respect to Microsoft Corporation, Broadcom Inc., Alphabet Inc. or Meta Platforms, Inc. which may or may not recommend that investors buy or hold the underlying stock.

￭The antidilution adjustments the calculation agent is required to make do not cover every corporate event that could affect the underlying stocks. MS & Co., as calculation agent, will adjust the adjustment factors for certain corporate events affecting the underlying stocks, such as stock splits, stock dividends and extraordinary dividends, and certain other corporate actions involving the issuers of the underlying stocks, such as mergers. However, the calculation agent will not make an adjustment for every corporate event that can affect the underlying stocks. For example, the calculation agent is not required to make any adjustments if the issuers of the underlying stocks or anyone else makes a partial tender or partial exchange offer for the underlying stocks, nor will adjustments be made following the calculation day. In addition, no adjustments will be made for regular cash dividends, which are expected to reduce the price of the underlying stocks by the amount of such dividends. If an event occurs that does not require the calculation agent to adjust an adjustment factor, such as a regular cash dividend, the market price of the securities and your return on the securities may be materially and adversely affected. For example, if the record date for a regular cash dividend were to occur on or shortly before the calculation day, this may decrease the ending price of an underlying stock to be less than its threshold price (resulting in a loss of a significant portion of all of your investment in the securities), materially and adversely affecting your return.

￭Historical closing prices of the underlying stocks should not be taken as an indication of the future performance of the underlying stocks during the term of the securities. No assurance can be given as to the price of the underlying stocks at any time, including on the calculation day, because historical closing prices of the underlying stocks do not provide an indication of future performance of the underlying stocks.

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 single financial contract that is an “open transaction” for U.S. federal income tax purposes.

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. 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.

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 Internal Revenue Code of 1986, as amended, and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% (or a lower applicable treaty rate) withholding tax on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities (each, an “Underlying Security”). Subject to certain exceptions, Section 871(m) generally applies to securities that substantially replicate the economic performance of one or more Underlying Securities, as determined based on tests set forth in the applicable Treasury regulations (a “Specified Security”). However, pursuant to an IRS notice, Section 871(m) will not apply to securities issued before January 1, 2027 that do not have a delta of one with respect to any Underlying Security. Based on our determination 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, 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.

In the opinion of Davis Polk & Wardwell LLP, as special counsel to MSFL and Morgan Stanley, when the securities offered by this pricing supplement have been issued by MSFL pursuant to the MSFL Senior Debt Indenture (as defined in the accompanying prospectus), the trustee and/or paying agent has made, in accordance with the instructions from MSFL, the appropriate entries or notations in its records relating to the master note that represents such securities (the “master note”), and such securities have been delivered against payment as contemplated herein, such securities will be valid and binding obligations of MSFL and the related guarantee will be a valid and binding obligation of Morgan Stanley, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability (including, without limitation, concepts of good faith, fair dealing and the lack of bad faith), provided that such counsel expresses no opinion as to (i) the effect of fraudulent conveyance, fraudulent transfer or similar provision of applicable law on the conclusions expressed above and (ii) any provision of the MSFL Senior Debt Indenture that purports to avoid the effect of fraudulent conveyance, fraudulent transfer or similar provision of applicable law by limiting the amount of Morgan Stanley’s obligation under the related guarantee.
