**Principal at Risk Securities Linked to an Unequally Weighted Basket Consisting of Five Indices due December 23, 2027**

***Fully and Unconditionally Guaranteed by Morgan Stanley***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ￭Linked to an unequally weighted basket composed of the EURO STOXX 50<sup>®</sup> Index (40.00% weighting), the Nikkei Stock Average (25.00% weighting), the FTSE<sup>®</sup> 100 Index (17.50% weighting), the Swiss Market Index<sup>®</sup> (10.00% weighting) and the S&P<sup>®</sup>/ASX 200 Index (7.50% weighting) (each referred to as a "basket component") <br> ￭The securities are unsecured obligations of Morgan Stanley Finance LLC ("MSFL") and are fully and unconditionally guaranteed by Morgan Stanley. The securities will pay no interest, provide for a payment at maturity that may be significantly less than the face amount and have the terms described in the accompanying product supplement for principal at risk securities, index supplement and prospectus, as supplemented or modified by this document. At maturity:<br> ￭If the level of the basket has increased, investors will receive the face amount *plus* a positive return equal to 200% of the percentage increase in the level of the basket from the starting level, subject to a maximum return at maturity of 23.60% of the face amount. As a result of the maximum return, the maximum maturity payment amount will be $1,236 per security. <br> ￭If the level of the basket has decreased, but the decrease is not more than the buffer amount of 10%, investors will receive the face amount.<br> ￭If the level of the basket decreases by more than the buffer amount of 10%, investors will receive less than the face amount and have downside exposure to the decrease in the level of the basket from the starting level to the ending level, subject to the buffering effect of a multiplier equal to approximately 1.1111, and you will lose approximately 1.1111% of the face amount for every 1% decline in the level of the basket in excess of the buffer amount of 10%.<br> ￭Investors may some, and possibly all, of the face amount of the securities.<br> ￭The securities are for investors who seek an equity index-based return and who are willing to risk their investment and forgo current income and upside above the maximum return in exchange for the participation rate and buffer features that in each case apply to a limited range of performance of the basket.<br> ￭The securities are notes issued as part of MSFL's Series A Global Medium-Term Notes program.<br> ￭All payments are subject to our credit risk. If we default on our obligations, you could lose some or all of your investment.<br> ￭These securities are not secured obligations and you will not have any security interest in, or otherwise have any access to, any securities included in the basket components.<br>

**The current estimated value of the securities is $968.10 per security. The estimated value of the securities is determined using our own pricing and valuation models, market inputs and assumptions relating to the basket components, instruments based on the basket components, 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.**

| &nbsp;&nbsp;&nbsp; **Estimated** **Value of the Securities** |
| &nbsp;&nbsp; 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 $968.10.<br> *What goes into the estimated value on the pricing date?*<br> 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 basket components. The estimated value of the securities is determined using our own pricing and valuation models, market inputs and assumptions relating to the basket components, instruments based on the basket components, 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.<br> *What determines the economic terms of the securities?*<br> In determining the economic terms of the securities, including the maximum return, the participation rate and the threshold level, 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.<br> *What is the relationship between the estimated value on the pricing date and the secondary market price of the securities?*<br> The price at which MS & Co. purchases the securities in the secondary market, absent changes in market conditions, including those related to the basket components, 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 basket components, 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.<br> 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. |

| &nbsp;&nbsp;&nbsp; **Investor** **Considerations** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Principal at Risk Securities Linked to a Basket Consisting of Five Indices due December 23, 2027 (the "securities") may be appropriate for investors who:<br> ￭seek as an alternative to direct exposure to the Basket that enhances returns for any positive performance of the Basket, subject to the maximum return;<br> ￭to enhance returns and potentially outperform the Basket in a bullish scenario<br> ￭understand that if the ending level is less than the threshold level, they will be exposed to the decrease in the Basket from the starting level in excess of the buffer amount, subject to the buffering effect of the multiplier, and will lose some, and possibly all, of the face amount of the securities at maturity<br> ￭desire to achieve similar levels of upside exposure to the basket components as a direct investment, while using fewer dollars by taking advantage of the participation rate, subject to the maximum return; and<br> ￭desire to obtain a buffer against a specified level of negative performance in the Basket.<br> The securities are not designed for, and may not be an appropriate investment for, investors who:<br> ￭seek a liquid investment or are unable or unwilling to hold the securities to maturity;<br> ￭are unwilling to accept the risk that the ending level of the Basket may decrease by more than the buffer amount of 10% from the starting level, resulting in a loss of some or possibly all of the initial investment;<br> ￭seek uncapped exposure to the upside performance of the Basket ;<br> ￭seek full return of the face amount of the securities at maturity;<br> ￭seek current income from their investments;<br> ￭seek exposure to the Basket but are unwilling to accept the risk/return trade-offs inherent in the payment at maturity for the securities;<br> ￭are unwilling to accept our credit risk; or<br> ￭prefer the lower risk of fixed income investments with comparable maturities issued by companies with comparable credit ratings. |

**The considerations identified above are not exhaustive. Whether or not the securities are an appropriate investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisors have carefully considered the appropriateness of an investment in the securities in light of your particular circumstances. You should also review carefully the "Risk Factors" herein and in the accompanying product supplement for risks related to an investment in the securities. For more information about the Basket and the basket components, please see the information provided herein.**

&nbsp;&nbsp;&nbsp; **Scenario** **Analysis and Examples of Maturity Payment Amount at Maturity**<br>

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

---

| | |
|:---|:---|
| &nbsp;&nbsp; Investment term: | &nbsp;&nbsp; 2 years |
| &nbsp;&nbsp; Starting level: | &nbsp;&nbsp; 100.00 |
| &nbsp;&nbsp; Threshold level: | &nbsp;&nbsp; 90.00 (90% of the starting level) |
| &nbsp;&nbsp; Hypothetical initial component level: | &nbsp;&nbsp; For each basket component, 100.00 |
| &nbsp;&nbsp; Buffer amount:  | &nbsp;&nbsp; 10% |
| &nbsp;&nbsp; Multiplier:  | &nbsp;&nbsp; Approximately 1.1111 |
| &nbsp;&nbsp; Participation rate: | &nbsp;&nbsp; 200% |
| &nbsp;&nbsp; Maximum return: | &nbsp;&nbsp; 23.60% of the face amount ($236 per security) |

---

<sup>\*</sup>The hypothetical initial component level of 100.00 for each basket component has been chosen for illustrative purposes only and does not represent the actual initial component level of any basket component. The actual initial component level for each basket component is set forth under "Final Terms" above. For historical data regarding the actual closing levels of the basket components, see the historical information set forth herein.

**Example 1** — **The level of the Basket *increases* from a starting level of 100.00 to an ending level of 110.00.** 

---

| | |
|:---|:---|
| &nbsp;&nbsp; Hypothetical final component level: | SX5E Index: 105 |
|  | NKY Index: 105 |
|  | UKX Index: 115 |
|  | SMI Index: 115 |
|  | AS51 Index: 135 |
| &nbsp;&nbsp; Hypothetical component return: | SX5E Index: (105 – 100) / 100 = 5%<br> NKY Index: (105 – 100) / 100 = 5%<br> UKX Index: (115 – 100) / 100 = 15%<br>SMI Index: (115 – 100) / 100 = 15%<br>AS51 Index: (135 – 100) / 100 = 35% |

---

Based on the hypothetical component returns set forth above, the hypothetical ending level would equal:

100 × [1 + (5.00% × 40.00%) + (5.00% × 25.00%) + (15.00% × 17.50%) + (15.00% × 10.00%) + (35.00% × 7.50%)] = 110.00

Because the hypothetical ending level is **greater than** the starting level, the maturity payment amount would equal $1,000 *plus* a positive return equal to *the lesser of*:

(i)$1,000 × basket return × participation rate <br>$1,000 × 10.00% × 200%<br>= $200.00, and

(ii)the maximum return of $236

On the maturity date, you would receive the maturity payment amount equal to $1,200.00 per $1,000 face amount of securities, resulting in a total return on the securities of 20.00%.

**Example 2 — The level of the Basket increases from a starting level of 100.00 to an ending level of 162.00.** 

<br> Hypothetical final component level: SX5E Index: 150 <br> NKY Index: 170

| &nbsp;&nbsp; Hypothetical component return: | SX5E Index: (150 – 100) / 100 = 50%<br> NKY Index: (170 – 100) / 100 = 70%<br> UKX Index: (180 – 100) / 100 = 80% |
|  | SMI Index: (160 – 100) / 100 = 60% |
|  | AS51 Index: (160 – 100) / 100 = 60% |

---

Based on the hypothetical component returns set forth above, the hypothetical ending level would equal:

100 × [1 + (50.00% × 40.00%) + (70.00% × 25.00%) + (80.00% × 17.50%) + (60.00% × 10.00%) + (60.00% × 7.50%)] = 162.00

Because the hypothetical ending level is **greater than** the starting level, the maturity payment amount would equal $1,000 *plus* a positive return equal to the *lesser of*:

(i)$1,000 × basket return × participation rate <br>$1,000 × 62% × 200%<br>= $1,240.00, and

(ii)the maximum return of $236

On the maturity date, you would receive the maturity payment amount equal to $1,236 per $1,000 face amount of securities (which is the maximum maturity payment amount), resulting in a total return on the securities of 23.60%. The appreciation potential of the securities is limited by the maximum return. Although the participation rate provides 200% exposure to any increase in the ending level over the starting level, because the maturity payment amount will be limited to 123.60% of the face amount for the securities, any increase in the ending level over the starting level by more than 11.80% of the starting level will not further increase the return on the securities.

**Example 3** — **The level of the Basket *decreases* from a starting level of 100.00 to an ending level of 90.50.**

| &nbsp;&nbsp; Hypothetical final component level: | SX5E Index: 80<br> NKY Index: 98 |
|  | UKX Index: 105 |
|  | SMI Index: 85 |
|  | AS51 Index: 95 |
| &nbsp;&nbsp; Hypothetical component return: | SX5E Index: (80 – 100) / 100 = -20%<br> NKY Index: (98 – 100) / 100 = -2%<br> UKX Index: (105 – 100) / 100 = 5%<br> SMI Index: (85 – 100) / 100 = -15% |
|  | AS51 Index: (95 – 100) / 100 = -5% |

---

Based on the hypothetical component returns set forth above, the hypothetical ending level would equal:

100 × [1 + (-20.00% × 40.00%) + (-2.00% × 25.00%) + (5.00% × 17.50%) + (-15.00% × 10.00%) + (-5.00% × 7.50%)] = 90.50

Because the hypothetical ending level is **less than or equal to** the starting level but **greater than or equal to** the threshold level, the maturity payment amount would equal:

$1,000

Because the hypothetical ending level is less than or equal to the starting level but greater than or equal to the threshold level, you would receive the maturity payment amount equal to $1,000 per $1,000 face amount of securities, resulting in a total return on the securities of 0%.

**Example 4** — **The level of the Basket *decreases* from a starting level of 100.00 to an ending level of 30.00.**

| &nbsp;&nbsp; Hypothetical final component level: | SX5E Index: 20<br>NKY Index: 34 |
|  | UKX Index: 50 |
|  | SMI Index: 40 |
|  | AS51 Index: 10 |
| &nbsp;&nbsp; Hypothetical component return: | SX5E Index: (20 – 100) / 100 = -80% |

---

Based on the hypothetical component returns set forth above, the hypothetical ending level would equal:

100 × [1 + (-80.00% × 40.00%) + (-66.00% × 25.00%) + (-50.00% × 17.50%) + (-60.00% × 10.00%) + (-90.00% × 7.50%)] = 30.00

Because the hypothetical ending level is **less than** the starting level by more than the buffer amount of 10%, you would lose a significant portion of the face amount of your securities and receive the maturity payment amount equal to:

$1,000 + [$1,000 × (basket return + buffer amount) × multiplier]

$1,000 + [$1,000 × (-70% + 10%) × 1.1111]

= $333.33

Because the ending level is **less than** the threshold level on the calculation day, investors will lose approximately 1.1111% of the face amount for every 1% decline in the level of the Basket in excess of the buffer amount of 10%. Therefore, the maturity payment amount is equal to $333.33 per $1,000 face amount of securities, resulting in a total loss on the securities of 66.666%.

***If the ending level is less than the threshold level on the calculation day, the securities will be subject to the buffering effect of a multiplier equal to approximately 1.1111, and will lose approximately 1.1111% of the face amount for every 1% decline in the level of the Basket in excess of the buffer amount of 10%. Under these circumstances, you may lose some, and possibly all, of the face amount of your securities at maturity.***

&nbsp;&nbsp;&nbsp; **Risk** **Factors**<br>

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

<u>Risks Relating to an Investment in the Securities</u>

￭**The securities do not pay interest, and you will lose some, and possibly all, of the face amount of your securities at maturity if the ending level is less than the threshold level.** The terms of the securities differ from those of ordinary debt securities in that the securities do not pay interest or repay a fixed amount of the face amount of the securities. If the ending level is less than the threshold level, which is 90% of the starting level, you will receive less than, and possibly lose all of, the face amount of your securities at maturity. Specifically, if the ending level is less than the threshold level, you will lose approximately 1.1111% of the face amount for every 1% that the ending level is less than the threshold level. **Investors may lose some, and possibly all, of their investment in the securities.**

￭**The appreciation potential of the securities is limited by the maximum return.** The appreciation potential of the securities is limited by the maximum return. Although the participation rate provides 200% exposure to any increase in the ending level over the starting level, because any positive return on the securities will be limited to the maximum return of 23.60% of the face amount for the securities, any increase in the ending level over the starting level by more than 11.80% of the starting level, will not further increase the return on the securities.

￭**The buffering effect of the multiplier will decrease as the ending level decreases.** If the ending level is less than the threshold level, the maturity payment amount will reflect the buffering effect of the multiplier, such that the maturity payment amount will be greater than it would have been had it been based solely on the performance of the Basket from the starting level to the ending level. As the performance of the Basket declines, however, the outperformance of the securities relative to the performance of the Basket will decline as well, because the multiplier only acts to buffer the performance of the Basket on a percentage basis. For example, if the ending level is 70% of the starting level, the maturity payment amount would be equal to $777.78 per security ($1,000 × .70 × multiplier), which is $77.78 greater than it would have been had it been based solely on the performance of the Basket without the multiplier (i.e., $700). However, if the ending level is 40% of the starting level, the maturity payment amount would be equal to $444.44 per security ($1,000 × .40 × multiplier), which is only $44.44 greater than it would have been had it been based solely on the performance of the Basket without the multiplier (i.e., $400). If the ending level is zero, the maturity payment amount will be zero ($1,000 × .00 × multiplier).

￭**The market price will be influenced by many unpredictable factors.** Several factors, many of which are beyond our control, will influence the value of the securities in the secondary market and the price at which MS & Co. or any other dealer may be willing to purchase or sell the securities in the secondary market, including the level and volatility (frequency and magnitude of changes in level) and dividend yield of the basket components, interest and yield rates in the market, the time remaining until the securities mature, geopolitical conditions and economic, financial, political, regulatory or judicial events that affect the basket components or equities markets generally and which may affect the ending level and any actual or anticipated changes in our credit ratings or credit spreads. Generally, the longer the time remaining to maturity, the more the market price of the securities will be affected by the other factors described above. The levels of the basket components may be, and has recently been, volatile, and we can give you no assurance that the volatility will lessen. See "EURO STOXX 50<sup>®</sup> Index Overview," "Nikkei Stock Average Overview," "FTSE<sup>®</sup> 100 Index," "Swiss Market Index<sup>®</sup> Overview" and "S&P<sup>®</sup>/ASX 200 Index" below. You may receive less than, and possibly lose all of, the face amount per security if you try to sell your securities prior to maturity.

￭**The securities are subject to our credit risk, and any actual or anticipated changes to our credit ratings or credit spreads may adversely affect the market value of the securities.** You are dependent on our ability to pay all amounts due on the securities at maturity, and therefore you are subject to our credit risk. If we default on our obligations under the securities, your investment would be at risk and you could lose some or all of your investment. As a result, the market value of the securities prior to maturity will be affected by changes in the market's view of our creditworthiness. Any actual or anticipated decline in our credit ratings or increase in the credit spreads charged by the market for taking our credit risk is likely to adversely affect the market value of the securities.

￭**As a finance subsidiary, MSFL has no independent operations and will have no independent assets.** As a finance subsidiary, MSFL has no independent operations beyond the issuance and administration of its securities and will have no independent assets available for distributions to holders of MSFL securities if they make claims in respect of such securities in a bankruptcy, resolution or similar proceeding. Accordingly, any recoveries by such holders will be limited to those available under the related guarantee by Morgan Stanley and that guarantee will rank *pari passu* with all other unsecured, unsubordinated obligations of Morgan Stanley. Holders will have recourse only to a single claim against Morgan Stanley and its assets under the

**Morgan Stanley Finance LLC**

**Market Linked Securities — Leveraged Upside Participation to a Cap and Buffered Downside with Multiplier**

**Principal at Risk Securities Linked to an Unequally Weighted Basket Consisting of Five Indices due December 23, 2027**

guarantee. Holders of securities issued by MSFL should accordingly assume that in any such proceedings they would not have any priority over and should be treated *pari passu* with the claims of other unsecured, unsubordinated creditors of Morgan Stanley, including holders of Morgan Stanley-issued securities.

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

￭**Investing in the securities is not equivalent to investing in the basket components.** Investing in the securities is not equivalent to investing directly in the basket components or any of the component stocks of the basket components. Investors in the securities will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the basket components or any of the component stocks of the basket components.

￭**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 basket components, 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.

**Principal at Risk Securities Linked to an Unequally Weighted Basket Consisting of Five Indices due December 23, 2027**

￭**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 initial component levels, the starting level, the threshold level and the ending level and will calculate the amount of cash you receive at maturity. Moreover, certain determinations made by MS & Co., in its capacity as calculation agent, may require it to exercise discretion and make subjective judgments, such as with respect to the occurrence or non-occurrence of market disruption events and the selection of a successor index or calculation of the ending level in the event of a market disruption event or discontinuance of the relevant basket component. These potentially subjective determinations may adversely affect the payout to you at maturity. For further information regarding these types of determinations, see "General Terms of the Securities—Market Disruption Events," "—Adjustments to an Index," ""—Discontinuance of an Index," "—Consequences of a Market Disruption Event; Postponement of a Calculation Day" and "Alternate Exchange Calculation in Case of an Event of Default" in the accompanying product supplement for principal at risk securities. In addition, MS & Co. has determined the estimated value of the securities on the pricing date.

￭**Hedging and trading activity by our affiliates could potentially adversely affect the value of the securities.** One or more of our affiliates and/or third-party dealers expect to carry out hedging activities related to the securities (and possibly to other instruments linked to the basket components or component stocks of the basket components), including trading in the stocks that constitute the basket components as well as in other instruments related to the basket components. As a result, these entities may be unwinding or adjusting hedge positions during the term of the securities, and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the calculation day approaches. Some of our affiliates also trade the stocks that constitute the basket components and other financial instruments related to the basket components 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 increase the initial basket levels, and, therefore, could increase the levels at or above which the basket components must close on the calculation day so that investors do not suffer a loss, and possibly a significant loss, on their initial investment in the securities. Additionally, such hedging or trading activities during the term of the securities, including on the calculation day, could adversely affect the final component levels, and therefore, the ending level, and, accordingly, the amount of cash an investor will receive at maturity, if any.

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

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

￭**The U.S. federal income tax consequences of an investment in the securities are uncertain.** Please read the discussion under "Additional Information About the Securities—Tax considerations" in this document and the discussion under "United States Federal Taxation" in the accompanying product supplement for principal at risk securities (together, the "Tax Disclosure Sections") concerning the U.S. federal income tax consequences of an investment in the securities. There is no direct legal authority regarding the proper U.S. federal tax treatment of the securities, and we do not plan to request a ruling from the Internal Revenue Service (the "IRS"). Consequently, significant aspects of the tax treatment of the securities are uncertain, and the IRS or a court might not agree with the tax treatment of a security as a single financial contract that is an "open transaction" for U.S. federal income tax purposes. If the IRS were successful in asserting an alternative treatment of the securities, the tax consequences of the ownership and disposition of the securities, including the timing and character of income recognized by U.S. Holders and the withholding tax consequences to Non-U.S. Holders, might be materially and adversely affected. Moreover, future legislation, Treasury regulations or IRS guidance could adversely affect the U.S. federal tax treatment of the securities, possibly retroactively.

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

<u>Risks Relating to the</u> <u>Basket</u>

￭**Changes in the levels of the basket components may offset each other.** Level movements in the basket components may not correlate with each other. At a time when the levels of one or more basket components increase, the values of the other basket components may not increase as much, or may even decline. Therefore, in calculating the basket components' performance on the

**Principal at Risk Securities Linked to an Unequally Weighted Basket Consisting of Five Indices due December 23, 2027**

calculation day, increases in the levels of one or more basket components may be moderated, or wholly offset, by lesser increases or declines in the levels of other basket components.

￭**The basket components are not equally weighted.** The securities are linked to a basket of five basket components, and the basket components have significantly different weights in determining the value of the basket. The same percentage change in each of the basket components would therefore have different effects on the ending level because of the unequal weighting. For example, if the weighting of one basket component is greater than the weighting of another basket component, a 5% decrease in the level of the basket component with the greater weighting will have a greater impact on the ending level than a 5% increase in the level of the basket component with the lesser weighting.

￭**There are risks associated with investments in securities linked to the value of foreign equity securities.** The securities are linked to the value of foreign equity securities. Investments in securities linked to the value of foreign equity securities involve risks associated with the securities markets in those countries, including risks of volatility in those markets, governmental intervention in those markets and cross-shareholdings in companies in certain countries. Also, there is generally less publicly available information about foreign companies than about U.S. companies that are subject to the reporting requirements of the United States Securities and Exchange Commission, and foreign companies are subject to accounting, auditing and financial reporting standards and requirements different from those applicable to U.S. reporting companies. The prices of securities issued in foreign markets may be affected by political, economic, financial and social factors in those countries, or global regions, including changes in government, economic and fiscal policies and currency exchange laws. Local securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times. Moreover, the economies in such countries may differ favorably or unfavorably from the economy in the United States in such respects as growth of gross national product, rate of inflation, capital reinvestment, resources, self-sufficiency and balance of payment positions between countries.

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

￭**Historical levels of the basket components should not be taken as an indication of the future performance of the basket components during the term of the securities.** No assurance can be given as to the level of the basket components at any time, including on the calculation day, because historical levels of the basket components do not provide an indication of future performance of the basket components.

**Principal at Risk Securities Linked to an Unequally Weighted Basket Consisting of Five Indices due December 23, 2027**

&nbsp;&nbsp;&nbsp; **Basket** **Overview**<br>

The Basket will represent a portfolio of the following five basket components, with the return of each basket component having the weighting noted parenthetically: EURO STOXX 50<sup>®</sup> Index (40.00%), the Nikkei Stock Average (25.00%), the FTSE<sup>®</sup> 100 Index (17.50%), Swiss Market Index<sup>®</sup> (10.00%) and the S&P<sup>®</sup>/ASX 200 (7.50%). The level of the Basket will increase or decrease depending upon the aggregate performance of the basket components. For more information regarding the basket components, see "EURO STOXX 50<sup>®</sup> Index Overview," "Nikkei Stock Average Overview," "FTSE<sup>®</sup> 100 Index," "Swiss Market Index<sup>®</sup> Overview" and "S&P<sup>®</sup>/ASX 200 Index." The Basket does not reflect the performance of all major securities markets.

While historical information on the level of the Basket does not exist, the following graph sets forth the hypothetical historical daily levels of the Basket for the period from January 1, 2020 to December 18, 2025, assuming that the Basket was constructed on January 1, 2020 with a starting level of 100 and that each of the basket components had the applicable weighting as of such day. We obtained the closing levels and other information used by us in order to create the graph below from Bloomberg Financial Markets ("<u>Bloomberg</u>") without independent verification.

The hypothetical historical basket levels, as calculated solely for the purposes of the offering of the securities, fluctuated in the past and may, in the future, experience significant fluctuations. Any historical upward or downward trend in the levels of the Basket during any period shown below is not an indication that the percentage change in the level of the Basket is more likely to be positive or negative during the term of the securities. The hypothetical historical levels do not give an indication of future levels of the Basket.

There can be no assurance that the performance of the Basket will not result in a loss of the principal amount of the securities.

**Principal at Risk Securities Linked to an Unequally Weighted Basket Consisting of Five Indices due December 23, 2027**

&nbsp;&nbsp;&nbsp; **Additional** **Information About the Securities**<br>

**Minimum ticketing size**

$1,000 / 1 security

**Tax considerations**

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

Assuming this treatment of the securities is respected and subject to the discussion in "United States Federal Taxation" in the accompanying product supplement for principal at risk securities, the following U.S. federal income tax consequences should result based on current law:

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

￭Upon sale, exchange or settlement of the securities, a U.S. Holder should recognize gain or loss equal to the difference between the amount realized and the U.S. Holder's tax basis in the securities. Such gain or loss should be long-term capital gain or loss if the investor has held the securities for more than one year, and short-term capital gain or loss otherwise.

We do not plan to request a ruling from the Internal Revenue Service (the "IRS") regarding the treatment of the securities. An alternative characterization of the securities could materially and adversely affect the tax consequences of ownership and disposition of the securities, including the timing and character of income recognized. In addition, the U.S. Treasury Department and the IRS have requested comments on various issues regarding the U.S. federal income tax treatment of "prepaid forward contracts" and similar financial instruments and have indicated that such transactions may be the subject of future regulations or other guidance. Furthermore, members of Congress have proposed legislative changes to the tax treatment of derivative contracts. Any legislation, Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, possibly with retroactive effect.

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

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

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

**The discussion in the preceding paragraphs under "Tax considerations" and the discussion contained in the section entitled "United States Federal Taxation" in the accompanying product supplement for principal at risk securities, insofar as they purport to describe provisions of U.S. federal income tax laws or legal conclusions with respect thereto, constitute the full opinion of Davis Polk & Wardwell LLP regarding the material U.S. federal tax consequences of an investment in the securities.**
