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

Principal at Risk Securities Linked to the Common Stock of Dick’s Sporting Goods, Inc. due October 22, 2027

Fully and Unconditionally Guaranteed by Morgan Stanley

\n \n \n \n \n \n \n

￭Linked to the common stock of Dick’s Sporting Goods, Inc. (the “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 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, tax supplement and prospectus, as supplemented or modified by this document.

￭Contingent Coupon. The securities will pay a contingent coupon on a monthly 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 month 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 month. 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 is 20.65% 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 $972.80 per security. 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, tax 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 is less than $1,000 per security. We estimate that the value of each security on the pricing date is $972.80.

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 Dick’s Sporting Goods, Inc. due October 22, 2027 (the “securities”) may be appropriate for investors who:

￭seek an investment with contingent coupon payments at a rate of 20.65% per annum until the earlier of the maturity date or automatic call, if, and only if, the stock closing price on the applicable monthly 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 and tax supplement for risks related to an investment in the securities. For more information about the underlying stock, please see the section titled “Dick’s Sporting Goods, Inc. Overview” below.

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

If the securities have not been previously automatically called, on each monthly 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 monthly 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 are set forth under “Final Terms” above. 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*:

\n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n

\n	\n
\n Contingent coupon payment: \n	\n 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. \n If payable, the contingent coupon payment will be an amount in cash per face amount corresponding to a return of 20.65% per annum for each interest payment period for each applicable calculation day. These hypothetical examples reflect the contingent monthly coupon rate of 20.65% (corresponding to $17.208 per month per security**). \n 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. \n
\n Hypothetical starting price: \n	\n $100.00 \n
\n Hypothetical coupon threshold price: \n	\n $70.00, which is 70% of the hypothetical starting price \n
\n Hypothetical downside threshold price: \n	\n $70.00, which is 70% of the hypothetical starting price \n

* 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 are set forth under “ Final 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 number of days in the applicable payment period, calculated on a 30/360 day-count basis. The hypothetical contingent monthly coupon of $17.208 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 (which is the first calculation day following which the securities can be called), 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 monthly calculation days prior to (and excluding) the calculation day immediately preceding the automatic call. Therefore, you would receive the contingent monthly coupons with respect to those 3 calculation days, totaling $17.208 × 3 = $51.624‬, 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 + $17.208 = $1,017.208.

The total payment over the 6-month term of the securities is $51.624‬ + $1,017.208 = $1,068.832.

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 $17.208 × 11 = $189.288, and (ii) the maturity payment amount calculated as $1,000 + $17.208 = $1,017.208.

The total payment over the 1-year term of the securities is $189.288 + $1,017.208 = $1,206.496.

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

Principal at Risk Securities Linked to the Common Stock of Dick’s Sporting Goods, Inc. due October 22, 2027

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 20.65% over the 1-year term of the securities. This example, therefore, represents the maximum amount payable over the 1-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 20.65% 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 $17.208 × 5 = $86.04, but not for the other 6 calculation days, and (ii) the maturity payment amount calculated as $1,000 + $17.208 = $1,017.208.

The total payment over the 1-year term of the securities is $86.04 + $1,017.208 = $1,103.248.

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 1-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, tax supplement and prospectus. We also urge you to consult your investment, legal, tax, accounting and other advisers in connection with your investment in the securities.

Risks Relating to an Investment in the Securities

￭The securities do not guarantee the return of the face amount of your securities at maturity. The terms of the securities differ from those of ordinary debt securities in that they do not guarantee the return of the face amount of your securities at maturity. If the securities have not been 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 monthly 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 monthly 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 monthly 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

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 Dick’s Sporting Goods, Inc. due October 22, 2027

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 “Dick’s Sporting Goods, 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.

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 Dick’s Sporting Goods, Inc. due October 22, 2027

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

Risks Relating to the Underlying Stock

￭No affiliation with Dick’s Sporting Goods, Inc. Dick’s Sporting Goods, Inc. is not an affiliate of ours, is not involved with this offering in any way, and has 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 Dick’s Sporting Goods, Inc. in connection with this offering.

￭We may engage in business with or involving Dick’s Sporting Goods, Inc. without regard to your interests. We or our affiliates may presently or from time to time engage in business with Dick’s Sporting Goods, Inc. without regard to your interests and thus may acquire non-public information about Dick’s Sporting Goods, 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 Dick’s Sporting Goods, 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 stock. MS & Co., as calculation agent, will adjust the adjustment factor for certain corporate events affecting the underlying stock, such as stock splits, stock dividends and extraordinary dividends, and certain other corporate actions involving the issuer of the underlying stock, such as mergers. 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 dividends, which are expected to reduce the price of the underlying stock by the amount of such dividends. If an event occurs that does not require the calculation agent to adjust the 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 a calculation day, this may decrease the stock closing price to be less than the coupon threshold price (resulting in no contingent coupon payment being paid with respect to such date) or the ending price to be less than the downside 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 stock should not be taken as an indication of the future performance of the underlying stock during the term of the securities. No assurance can be given as to the price of the underlying stock at any time, including on the final calculation day, because historical closing prices of the underlying stock do not provide an indication of future performance of the underlying stock.

United States federal income tax considerations

You should review carefully the section in the accompanying tax supplement entitled “United States Federal Taxation.” The following discussion, when read in combination with that section, constitutes the full opinion of our counsel, Davis Polk & Wardwell LLP, regarding the material U.S. federal income tax consequences of owning and disposing of the securities offered by this pricing supplement.

Generally, this discussion assumes that you purchased a security for cash in the original issuance at the stated issue price and does not address other circumstances specific to you, including consequences that may arise due to any other investments relating to an underlier. Moreover, as discussed in the section entitled “United States Federal Taxation” in the accompanying tax supplement, we have not attempted to ascertain whether any issuer of any underlier to which the securities relate is a U.S. real property holding corporation or a passive foreign investment company. You should consult your tax adviser regarding these issues, including the effect any circumstances specific to you may have on the U.S. federal income tax consequences of your ownership of a security.

In the opinion of our counsel, which is based on current market conditions, it is reasonable to treat the securities for U.S. federal income tax purposes as prepaid financial contracts with associated coupons, and any coupons as ordinary income, as described in the section entitled “United States Federal Taxation—Tax Consequences to U.S. Holders—Program Securities Treated as Prepaid Financial Contracts with Associated Coupons” in the accompanying tax supplement. There is uncertainty regarding this treatment, and the Internal Revenue Service (the “IRS”) or a court might not agree with it. A different tax treatment could be adverse to you.

We do not plan to request a ruling from the IRS regarding the treatment of the securities. An alternative characterization of the securities could materially and adversely affect the tax consequences of ownership and disposition of the securities, including the timing and character of income recognized. In particular, due to the terms of the securities and current market conditions, there is a risk that the securities could be characterized as debt instruments for U.S. federal income tax purposes, in which case the timing and character of income recognized in respect of the securities could be different from those described herein and possibly adverse to certain investors. In addition, the U.S. Treasury Department and the IRS have requested comments on various issues regarding the U.S. federal income tax treatment of “prepaid forward contracts” and similar financial instruments and have indicated that such transactions may be the subject of future regulations or other guidance. Furthermore, members of Congress have proposed legislative changes to the tax treatment of derivative contracts. Any legislation, Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, possibly with retroactive effect.

Non-U.S. Holders. If you are a Non-U.S. Holder (as defined in the accompanying tax supplement), please also read the section entitled “United States Federal Taxation—Tax Consequences to Non-U.S. Holders—Program Securities Not Treated as Debt Instruments” in the accompanying tax supplement.

The U.S. federal income tax treatment of the coupons is unclear. To the extent that we have withholding responsibility in respect of the securities, we would expect generally to treat the coupons paid to Non-U.S. Holders as subject to U.S. withholding tax. Moreover, you should expect that, if the applicable withholding agent determines that withholding tax should apply, it will be at a rate of 30% (or lower treaty rate). In order to claim an exemption from, or a reduction in, the 30% withholding under an applicable treaty, you may need to comply with certification requirements to establish that you are not a U.S. person and are eligible for such an exemption or reduction under an applicable tax treaty. You should consult your tax adviser regarding the tax treatment of the coupons.

As discussed under “United States Federal Taxation—Tax Consequences to Non-U.S. Holders—Dividend Equivalents under Section 871(m) of the Code” in the accompanying tax supplement, Section 871(m) of the Internal Revenue Code and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% withholding tax on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities. The Treasury regulations, as modified by an IRS notice, exempt financial instruments issued prior to January 1, 2029 that do not have a “delta” of one. Based on certain representations made by us, our counsel is of the opinion that Section 871(m) should not apply to the securities with regard to Non-U.S. Holders. Our determination is not binding on the IRS, and the IRS may disagree with this determination.

We will not be required to pay any additional amounts with respect to U.S. federal withholding taxes.

You should consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments, as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Validity of the securities
