Market Linked Securities—Auto-Callable with Contingent Coupon and Contingent Downside

Principal at Risk Securities Linked to the Common Stock of Micron Technology, Inc. due October 21, 2027

Fully and Unconditionally Guaranteed by Morgan Stanley

￭Linked to the common stock of Micron Technology, Inc. (the “underlying stock”)

￭The securities offered are unsecured obligations of Morgan Stanley Finance LLC (“MSFL”) and are fully and unconditionally guaranteed by Morgan Stanley. Unlike ordinary debt securities, the securities do not guarantee the payment of interest, do not guarantee the repayment of principal and are subject to potential 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.

￭Contingent Coupon. The securities will pay a contingent coupon on a quarterly basis until the earlier of the maturity date or automatic call if, and only if, the stock closing price on the calculation day for that quarter is greater than or equal to the coupon threshold price. However, if the stock closing price on a calculation day is less than the coupon threshold price, you will not receive any contingent coupon payment for the relevant quarter. If the stock closing price is less than the coupon threshold price on every calculation day, you will not receive any contingent coupon payments throughout the entire term of the securities. The coupon threshold price is equal to 70% of the starting price. The contingent coupon rate will be determined on the pricing date and will be at least 17.15% per annum.

￭Automatic Call. Beginning after six months, the securities will be automatically called if the stock closing price on any of the calculation days (other than the final calculation day) is greater than or equal to the starting price for a cash payment equal to the face amount plus a final contingent coupon payment. No further payments will be made on the securities once they have been called.

￭Potential Loss of Principal. If the securities are not automatically called prior to maturity, you will receive the face amount at maturity if, and only if, the ending price is greater than or equal to the downside threshold price. If the ending price is less than the downside threshold price, investors will be fully exposed to the decline in the underlying stock on a 1-to-1 basis and will receive a maturity payment amount that is less than 70% of the face amount of the securities and could be zero.

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

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

￭Investors will not participate in any appreciation of the 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 stock.

The current estimated value of the securities is approximately $956.70 per security, or within $35.00 of that estimate. The estimated value of the securities is determined using our own pricing and valuation models, market inputs and assumptions relating to the underlying stock, instruments based on the underlying stock, 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.

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 $956.70, or within $35.00 of that estimate. Our estimate of the value of the securities as determined on the pricing date will be set forth in the final pricing supplement.

What goes into the estimated value on the pricing date?

In valuing the securities on the pricing date, we take into account that the securities comprise both a debt component and a performance-based component linked to the underlying stock. The estimated value of the securities is determined using our own pricing and valuation models, market inputs and assumptions relating to the underlying stock, instruments based on the underlying stock, volatility and other factors including current and expected interest rates, as well as an interest rate related to our secondary market credit spread, which is the implied interest rate at which our conventional fixed rate debt trades in the secondary market.

What determines the economic terms of the securities?

In determining the economic terms of the securities, including the contingent coupon rate, the coupon threshold price and the downside threshold price, 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 stock, 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 stock, 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 Common Stock of Micron Technology, Inc. due October 21, 2027 (the “securities”) may be appropriate for investors who:

￭seek an investment with contingent coupon payments at a rate of at least 17.15% per annum (to be determined on the pricing date) until the earlier of the maturity date or automatic call, if, and only if, the stock closing price on the applicable quarterly calculation day is greater than or equal to 70% of the starting price;

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

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

￭understand that the securities may be automatically called prior to the maturity date and that the term of the securities may be as short as approximately six months;

￭understand and are willing to accept the full downside risks of the underlying stock;

￭are willing to forgo participation in any appreciation of the underlying stock, fixed interest payments on the securities and dividends on the underlying stock; and

￭are willing to hold the securities until maturity.

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

￭seek a liquid investment or are unable or unwilling to hold the securities to maturity;

￭require full payment of the face amount of the securities at maturity;

￭seek a security with a fixed term;

￭are unwilling to accept the risk that the stock closing price may decline by more than 30% from the starting price to the ending price, in which case they will lose a significant portion or all of their investment;

￭seek current income;

￭are unwilling to accept the risk of exposure to the underlying stock;

￭seek exposure to the upside performance of the underlying stock;

￭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.

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

If the securities have not been previously automatically called, on each quarterly contingent coupon payment date, you will either receive a contingent coupon payment or you will not receive a contingent coupon payment, depending on the stock closing price on the related quarterly calculation day.

Determine whether a contingent coupon payment is paid on the applicable contingent coupon payment date based on the stock closing price on the relevant calculation day, as follows:

Beginning after six months, if the stock closing price on a calculation day is greater than or equal to the starting price, the securities will be automatically called on the applicable call settlement date for an amount in cash equal to $1,000 plus the related contingent coupon payment.

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

Scenario Analysis and Examples of Hypothetical Payments on the Securities

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

Hypothetical contingent coupon payment: On each contingent coupon payment date, you will receive a contingent coupon payment at a per annum rate equal to the contingent coupon rate if, and only if, the stock closing price on the related calculation day is greater than or equal to the coupon threshold price.

If payable, the contingent coupon payment will be an amount in cash per face amount corresponding to a return of 17.15% per annum for each interest payment period for each applicable calculation day. These hypothetical examples reflect a hypothetical contingent quarterly coupon rate of 17.15% (corresponding to $42.875 per quarter per security**).

It is possible that the stock closing price will be less than the coupon threshold price for extended periods of time or even throughout the entire term of the securities so that you will receive few or no contingent coupon payments.

Hypothetical starting price: $100.00

Hypothetical coupon threshold price: $70.00, which is 70% of the hypothetical starting price

Hypothetical downside threshold price: $70.00, which is 70% of the hypothetical starting price

* The hypothetical starting price of $100.00 for the underlying stock has been chosen for illustrative purposes only and does not represent the actual starting price of the underlying stock. The actual starting price, coupon threshold price and downside threshold price will be determined on the pricing date and will be set forth under “Terms” above. For historical data regarding the actual closing prices of the underlying stock, see the historical information set forth herein.

**The actual contingent coupon payment will be an amount determined by the calculation agent based on the actual contingent coupon rate. The hypothetical contingent quarterly coupon of $42.875 is used in these examples for ease of analysis.

In Example 1, the stock closing price fluctuates over the term of the securities and the stock closing price is greater than or equal to the hypothetical starting price of $100.00 on one of the calculation days following the 6-month non-call period. Because the stock closing price is greater than or equal to the starting price on such a date, the securities are automatically called on the related call settlement date. In Examples 2, 3 and 4, the stock closing price on each of the calculation days is less than the starting price, and, consequently, the securities are not automatically called prior to, and remain outstanding until, maturity.

Example 1 — The securities are automatically called following the sixth calculation day, as the stock closing price on the sixth calculation day is greater than or equal to the starting price. The stock closing price is greater than or equal to the coupon threshold price on only 3 of the 5 quarterly calculation days prior to (and excluding) the calculation day immediately preceding the automatic call. Therefore, you would receive the contingent quarterly coupons with respect to those 3 calculation days, totaling $42.875 × 3 = $128.625‬, but not for the other 2 calculation days. The stock closing price is equal to the starting price on the sixth calculation day. Upon automatic call, investors receive a cash payment per security calculated as $1,000 + $42.875 = $1,042.875.

The total payment over the 1.5-year term of the securities is $128.625‬ + $1,042.875 = $1,171.50.

Example 2 — The securities are not called prior to maturity, as the stock closing price is less than the starting price on every calculation day. The stock closing price is greater than or equal to the coupon threshold price on all 11 calculation days prior to (and excluding) the final calculation day, and the ending price is also greater than or equal to the coupon threshold price and the downside threshold price on the final calculation day. Therefore, you would receive (i) the contingent coupon payments with respect to the 11 calculation days prior to (and excluding) the final calculation day, totaling $42.875 × 11 = $471.625, and (ii) the maturity payment amount calculated as $1,000 + $42.875 = $1,042.875.

Market Linked Securities—Auto-Callable with Contingent Coupon and Contingent Downside

Principal at Risk Securities Linked to the Common Stock of Micron Technology, Inc. due October 21, 2027

The total payment over the 3-year term of the securities is $471.625 + $1,042.875 = $1,514.50.

This example illustrates the scenario where you receive a contingent coupon payment on every contingent coupon payment date throughout the term of the securities and receive your principal back at maturity, resulting in an annual interest rate of 17.15% over the 3-year term of the securities. This example, therefore, represents the maximum amount payable over the 3-year term of the securities. To the extent that the contingent coupon payments are not paid on every contingent coupon payment date, the effective rate of interest on the securities will be less than 17.15% per annum and could be zero.

Example 3 — The securities are not called prior to maturity, as the stock closing price is less than the starting price on every calculation day. The stock closing price is greater than or equal to the coupon threshold price on 5 out of the 11 calculation days prior to (and excluding) the final calculation day. The ending price is $100.00, which is greater than or equal to the downside threshold price. In this scenario, you receive a maturity payment amount equal to the stated principal amount plus a contingent coupon payment with respect to the final calculation day. Therefore, you would receive (i) the contingent coupon payments with respect to those 5 calculation days prior to (and excluding) the final calculation day, totaling $42.875 × 5 = $214.375, but not for the other 6 calculation days, and (ii) the maturity payment amount calculated as $1,000 + $42.875 = $1,042.875.

The total payment over the 3-year term of the securities is $214.375 + $1,042.875 = $1,257.25.

Example 4 — The securities are not called prior to maturity, as the stock closing price is less than the starting price on every calculation day. The stock closing price is also less than the coupon threshold price on every calculation day, including the final calculation day. The ending price is $40.00, which is less than the downside threshold price. Therefore, you would receive no contingent coupon payments throughout the entire term of the securities, and the maturity payment amount would be calculated as $1,000 × ($40.00 / $100.00) = $400.00.

The total payment over the 3-year term of the securities is $0 + $400.00 = $400.00.

If the securities are not automatically called prior to maturity and the ending price is less than the downside threshold price, investors will be exposed to the downside performance of the underlying stock at maturity, and the maturity payment amount will be less than 70% of the face amount per security and could be zero.

Risk Factors

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

Risks Relating to an Investment in the Securities

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

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

￭The contingent coupon payment, if any, is based on the stock closing price of the underlying stock on only the related quarterly calculation day at the end of the related interest period. Whether the contingent coupon payment will be paid on any contingent coupon payment date will be determined at the end of the relevant interest period based on the stock closing price of the underlying stock on the relevant quarterly calculation day. As a result, you will not know whether you will receive the contingent coupon payments on any contingent coupon payment date until near the end of the relevant interest period. Moreover, because the contingent coupon payment is based solely on the value of the underlying stock on the quarterly calculation days, if the stock closing price of the underlying stock on any calculation day is below the coupon threshold price, you will not receive the contingent coupon payment for the related interest period, even if the price of the underlying stock was at or above the coupon threshold price on other days during that interest period.

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

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

othe trading price and volatility (frequency and magnitude of changes in value) of the underlying stock,

owhether the stock closing price of the underlying stock has been below the coupon threshold price on any calculation day,

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

odividend rates on the underlying stock,

othe time remaining until the securities mature,

ointerest and yield rates in the market,

othe availability of comparable instruments,

othe occurrence of certain events affecting the underlying stock that may or may not require an adjustment to the adjustment factor, and

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

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

You cannot predict the future performance of the underlying stock based on its historical performance. The price of the underlying stock may be, and has recently been, volatile, and we can give you no assurance that the volatility will lessen. The price of the underlying stock may decrease and be below the coupon threshold price on each calculation day so that you will receive no return on your investment, and the underlying stock may close below the downside threshold price on the final calculation day so that you will lose a significant portion or all of your initial investment in the securities. There can be no assurance that the stock closing price will be at or above the coupon threshold price on any calculation day so that you will receive a coupon payment on the securities for the applicable interest period, or that it will be at or above the downside threshold price on the final calculation day so that you do not suffer a significant loss on your initial investment in the securities. See “Micron Technology, 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, on any contingent coupon payment date or at maturity, and therefore you are subject to our credit risk. If we default on our obligations under the securities, your investment would be at risk and you could lose some or all of your investment. As a result, the market value of the securities prior to maturity will be affected by changes in the market’s view of our creditworthiness. Any actual or anticipated decline in our credit ratings or increase in the credit spreads charged by the market for taking our credit risk is likely to adversely affect the market value of the securities.

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

￭Investing in the securities is not equivalent to investing in the underlying stock. Investing in the securities is not equivalent to investing in the underlying stock. Investors in the securities will not participate in any positive performance of the underlying stock, and will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the underlying stock. As a result, any return on the securities will not reflect the return you would realize if you actually owned shares of the underlying stock 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 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 within the first six months of the term of the 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 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 stock, 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 price, the coupon threshold price, the downside threshold price and the ending price, and will calculate the amount of cash you receive upon an automatic call or at maturity, if any. Moreover, certain determinations made by MS & Co., in its capacity as calculation agent, may require it to exercise discretion and make subjective judgments, such as with respect to the occurrence or non-occurrence of market disruption events and certain adjustments to the adjustment factor. These potentially subjective determinations may adversely affect the payout to you upon an automatic call or 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 stock), including trading in the underlying stock. As a result, these entities may be unwinding or adjusting hedge positions during the term of the securities, and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the final calculation day approaches. Some of our affiliates also trade the underlying stock and other financial instruments related to the underlying stock 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 the underlying stock, and, therefore, could increase (i) the price at or above which the underlying stock must close on the calculation days so that the securities are called for a cash payment equal to the face amount plus a final contingent coupon payment, (ii) the price at or above which the underlying stock must close on each calculation day in order for you to earn a contingent coupon payment and (iii) the price at or above which the underlying stock must close on the final calculation day so that you are not exposed to the negative performance of the underlying stock at maturity. Additionally, such hedging or trading activities during the term of the securities could potentially affect the price of the underlying stock on the calculation days, and, accordingly, whether we call the securities prior to maturity, whether we pay a contingent coupon payment on the securities and the amount of cash you will receive at maturity, if any.

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

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

￭The U.S. federal income tax consequences of an investment in the securities are uncertain. There is no direct legal authority as to the proper treatment of the securities for U.S. federal income tax purposes, and, therefore, significant aspects of the tax treatment of the securities are uncertain.

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

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

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 tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

However, the calculation agent will not make an adjustment for every corporate event that can affect the underlying stock. For example, the calculation agent is not required to make any adjustments if the issuer of the underlying stock or anyone else makes a partial tender or partial exchange offer for the underlying stock, nor will adjustments be made following the final calculation day. In addition, no adjustments will be made for regular cash

Tax considerations

Due to the absence of statutory, judicial or administrative authorities that directly address the treatment of the securities or instruments that are similar to the securities for U.S. federal income tax purposes, no assurance can be given that the IRS or a court will agree with the tax treatment described herein. We intend to treat a security for U.S. federal income tax purposes as a single financial contract that provides for a coupon that will be treated as gross income to you at the time received or accrued in accordance with your regular method of tax accounting. In the opinion of our counsel, Davis Polk & Wardwell LLP, this treatment of the securities is reasonable under current law; however, there are other reasonable treatments that the IRS or a court may adopt, in which case the timing and character of any income or loss on the securities could be materially affected. Moreover, our counsel’s opinion is based on market conditions as of the date of this preliminary pricing supplement and is subject to confirmation on the pricing date.

Tax Consequences to U.S. Holders

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

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

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

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

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

Tax Consequences to Non-U.S. Holders

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

Section 871(m) Withholding Tax on Dividend Equivalents

As discussed in the accompanying product supplement for principal at risk securities, Section 871(m) of the Code and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% (or a lower applicable treaty rate) withholding tax on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities (each, an “Underlying Security”). Subject to certain exceptions, Section 871(m) generally applies to securities that substantially replicate the economic performance of one or more Underlying Securities, as determined based on tests set forth in the applicable Treasury regulations (a “Specified Security”). However, pursuant to an IRS notice, Section 871(m) will not apply

October 2024 Page 16

Morgan Stanley Finance LLC

Market Linked Securities—Auto-Callable with Contingent Coupon and Contingent Downside

Principal at Risk Securities Linked to the Common Stock of Micron Technology, Inc. due October 21, 2027

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 pricing supplement. Assuming that the securities do not have a delta of one with respect to any Underlying Security, our counsel is of the opinion that the securities should not be Specified Securities and, therefore, should not be subject to Section 871(m).

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

Both U.S. and non-U.S. investors considering an investment in the securities should read the discussion under “Risk Factors” in this document and the discussion under “United States Federal Taxation” in the accompanying product supplement for principal at risk securities and consult their tax advisers regarding all aspects of the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments, 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.
