[424B2] Morgan Stanley Prospectus Supplement

Rhea-AI Filing Summary

Offering overview: Morgan Stanley Finance LLC is issuing $1.595 million of Contingent Income Auto-Callable Securities due July 30, 2026, fully and unconditionally guaranteed by Morgan Stanley. Each $1,000 principal-at-risk note pays no fixed interest and is linked to the worst performer of the Nasdaq-100 Technology Sector Index (NDXT) and the S&P 500 Index (SPX).

Income feature: A contingent coupon calculated at an annual rate of 9.50% (≈ $7.917 per monthly interest period) is paid only when, on the relevant observation date, the closing level of each index is at least 80 % of its initial level (coupon barrier: NDXT 9,240.208; SPX 4,938.456). Investors could receive few—or no—coupons if either index trades below its barrier.

Early redemption: Beginning with the first determination date on December 29 2025, the notes will be automatically called if both indices close at or above 100 % of their initial levels (11,550.26 for NDXT; 6,173.07 for SPX). The early redemption payment equals the $1,000 principal plus the contingent coupon for the period; no further payments are made thereafter.

Maturity payment: If not called, and both indices finish at or above their 80 % downside thresholds on July 27 2026, holders receive par plus any final coupon. If either index is below its threshold, repayment equals $1,000 multiplied by the performance of the worst-performing index, exposing investors to 1 % loss of principal for every 1 % decline, with potential loss of entire investment.

Pricing & distribution: Issue price $1,000; estimated value on pricing date $972.40 (reflecting internal funding rate and transaction costs). Agents earn a fixed $15 selling concession per note. The securities are not listed on any exchange, and secondary liquidity depends solely on MS&Co’s market-making discretion.

Key risks: 1) No principal protection; 2) Uncertain, contingent income; 3) Equity market, sector concentration and correlation risks; 4) Early call risk limits upside; 5) Credit exposure to Morgan Stanley; 6) Valuation likely to trail issue price; 7) Limited secondary market; 8) Uncertain U.S. tax treatment and possible 30 % withholding for non-U.S. holders.

Target investors: Yield-seeking investors comfortable with short-dated structured notes, equity index risk and potential total loss of principal, who do not require liquidity and accept Morgan Stanley credit exposure.

Positive

• High 9.5 % contingent coupon if both indices remain ≥ 80 % of initial levels.
• Full Morgan Stanley guarantee provides investment-grade credit backing.
• Automatic early redemption feature could return principal plus coupon in as little as six months post-December 2025.

Negative

• No principal protection; investors lose 1 % of principal per 1 % index decline below the 80 % threshold.
• Coupon uncertainty; payments cease whenever either index closes below its barrier.
• Issuer call optionality limits upside while leaving downside with investors.
• Estimated value (97.24 % of par) indicates immediate economic negative carry.
• Not exchange-listed; secondary market depends solely on MS&Co, risking illiquidity.
• Technology-sector concentration in NDXT amplifies volatility relative to broad market exposure.

Insights

Structured Products Analyst

TL;DR New MS auto-callable pays 9.5 % if both NDXT and SPX stay above 80 %; principal loss below 80 %; neutral for MS, high risk for buyers.

Impact assessment: The filing adds another routine structured note to Morgan Stanley’s shelf. Aggregate issuance size ($1.6 m) is immaterial to the bank’s balance sheet and carries standard margins. For noteholders, economics are typical: a rich headline coupon offsets equity downside and call risk. The 80 % barrier/downside threshold offers modest protection, but technology-sector concentration (NDXT) increases volatility. Estimated value (97.24 % of par) indicates a 2.8 % upfront cost to investors. Credit risk, liquidity constraints and uncertain tax treatment remain prevalent. Overall market impact is negligible; suitability hinges on individual risk tolerance.

Risk Analyst

TL;DR Product shifts market and credit risk to retail investors; early call skews returns; limited liquidity heightens exit risk.

The note embeds short put exposure below an 80 % strike while capping upside at the 9.5 % coupon. Because payoff depends on the worst performer, correlation risk is material—diversification benefit is illusory. Early redemption is issuer-friendly, crystallising gains if markets rally while leaving investors exposed in downturns. Secondary valuation will reflect MS credit spreads plus bid/ask, likely trading below the already discounted estimated value. For sophisticated clients this may serve as a yield enhancer, but for most retail buyers risk-adjusted return is unattractive. Conclusion: risk profile is skewed negative, though not material to Morgan Stanley’s credit.

Based on the Worst Performing of the Nasdaq-100® Technology Sector IndexSM and the S&P 500® Index

Fully and Unconditionally Guaranteed by Morgan Stanley

Principal at Risk Securities

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

￭Contingent coupon. The securities will pay a contingent coupon but only if the closing level of each underlier is greater than or equal to its coupon barrier level on the related observation date. However, if the closing level of either underlier is less than its coupon barrier level on any observation date, we will pay no interest with respect to the related interest period.

￭Automatic early redemption. The securities will be automatically redeemed if the closing level of each underlier is greater than or equal to its call threshold level on any redemption determination date for an early redemption payment equal to the stated principal amount plus the contingent coupon with respect to the related interest period. No further payments will be made on the securities once they have been automatically redeemed.

￭Payment at maturity. If the securities have not been automatically redeemed prior to maturity and the final level of each underlier is greater than or equal to its downside threshold level, investors will receive (in addition to the contingent coupon with respect to the final observation date, if payable) the stated principal amount at maturity. If, however, the final level of either underlier is less than its downside threshold level, investors will lose 1% for every 1% decline in the level of the worst performing underlier over the term of the securities. Under these circumstances, the payment at maturity will be significantly less than the stated principal amount and could be zero.

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

￭The securities are for investors who seek an opportunity to earn interest at a potentially above-market rate in exchange for the risk of losing a significant portion or all of their principal and the risk of receiving no coupons over the entire term of the securities. You will not participate in any appreciation of either underlier. Investors in the securities must be willing to accept the risk of losing their entire initial investment based on the performance of either underlier. The securities are notes issued as part of MSFL’s Series A Global Medium-Term Notes program.

￭All payments are subject to our credit risk. If we default on our obligations, you could lose some or all of your investment. These securities are not secured obligations and you will not have any security interest in, or otherwise have any access to, any underlying reference asset or assets.

Estimated Value of the Securities

The original issue price of each security is $1,000. This price includes costs associated with issuing, selling, structuring and hedging the securities, which are borne by you, and, consequently, the estimated value of the securities on the pricing date is less than $1,000. Our estimate of the value of the securities as determined on the pricing date is set forth on the cover of this document.

What goes into the estimated value on the pricing date?

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

What determines the economic terms of the securities?

In determining the economic terms of the securities, we use an internal funding rate, which is likely to be lower than our secondary market credit spreads and therefore advantageous to us. If the issuing, selling, structuring and hedging costs borne by you were lower or if the internal funding rate were higher, one or more of the economic terms of the securities would be more favorable to you.

What is the relationship between the estimated value on the pricing date and the secondary market price of the securities?

The price at which MS & Co. purchases the securities in the secondary market, absent changes in market conditions, including those related to the underliers, may vary from, and be lower than, the estimated value on the pricing date, because the secondary market price takes into account our secondary market credit spread as well as the bid-offer spread that MS & Co. would charge in a secondary market transaction of this type and other factors. However, because the costs associated with issuing, selling, structuring and hedging the securities are not fully deducted upon issuance, to the extent that MS & Co. may buy or sell the securities in the secondary market during the amortization period specified herein, absent changes in market conditions, including those related to the underliers, and to our secondary market credit spreads, it would do so based on values higher than the estimated value. We expect that those higher values will also be reflected in your brokerage account statements.

MS & Co. may, but is not obligated to, make a market in the securities, and, if it once chooses to make a market, may cease doing so at any time.

Hypothetical Examples

The following hypothetical examples illustrate how to determine whether the securities will be automatically redeemed with respect to a redemption determination date, whether a contingent coupon is payable with respect to an observation date and how to calculate the payment at maturity if the securities have not been automatically redeemed prior to maturity. The following examples are for illustrative purposes only. Whether the securities are automatically redeemed prior to maturity will be determined by reference to the closing level of each underlier on each redemption determination date. Whether you receive a contingent coupon will be determined by reference to the closing level of each underlier on each observation date. The payment at maturity will be determined by reference to the closing level of each underlier on the final observation date. The actual initial level, call threshold level, coupon barrier level and downside threshold level for each underlier were determined on the strike date. All payments on the securities are subject to our credit risk. The numbers in the hypothetical examples below may have been rounded for ease of analysis. The below examples are based on the following terms:

Stated principal amount:	$1,000 per security
Hypothetical initial level:	With respect to the NDXT Index, 100.00* With respect to the SPX Index, 100.00*
Hypothetical call threshold level:	With respect to the NDXT Index, 100.00, which is 100% of its hypothetical initial level With respect to the SPX Index, 100.00, which is 100% of its hypothetical initial level
Hypothetical coupon barrier level:	With respect to the NDXT Index, 80.00, which is 80% of its hypothetical initial level With respect to the SPX Index, 80.00, which is 80% of its hypothetical initial level
Hypothetical downside threshold level:	With respect to the NDXT Index, 80.00, which is 80% of its hypothetical initial level With respect to the SPX Index, 80.00, which is 80% of its hypothetical initial level
Contingent coupon:	9.50% per annum (corresponding to approximately $7.917 per interest period per security). The actual contingent coupon will be an amount determined by the calculation agent based on the number of days in the applicable payment period, calculated on a 30/360 day-count basis. The hypothetical contingent coupon of $7.917 is used in these examples for ease of analysis.

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

How to determine whether the securities will be automatically redeemed with respect to a redemption determination date:

	Closing Level		Early Redemption Payment
	NDXT Index	SPX Index
Hypothetical Redemption Determination Date #1	45.00 (less than its call threshold level)	110.00 (greater than or equal to its call threshold level)	N/A
Hypothetical Redemption Determination Date #2	125.00 (greater than or equal to its call threshold level)	115.00 (greater than or equal to its call threshold level)	$1,000 + $7.917 (the stated principal amount + the contingent coupon with respect to the related interest period) For more information, please see “How to determine whether a contingent coupon is payable with respect to an observation date (if the securities have not been previously automatically redeemed)” below.

On hypothetical redemption determination date #1, because the closing level of at least one underlier is less than its call threshold level, the securities are not automatically redeemed on the related early redemption date.

On hypothetical redemption determination date #2, because the closing level of each underlier is greater than or equal to its call threshold level, the securities are automatically redeemed on the related early redemption date for an early redemption payment equal to the stated principal amount plus the contingent coupon with respect to the related interest period. No further payments are made on the securities once they have been automatically redeemed.

If the closing level of either underlier is less than its call threshold level on each redemption determination date, the securities will not be automatically redeemed prior to maturity.

How to determine whether a contingent coupon is payable with respect to an observation date (if the securities have not been previously automatically redeemed):

	Closing Level		Payment per Security
	NDXT Index	SPX Index
Hypothetical Observation Date #1	125.00 (greater than or equal to its coupon barrier level)	115.00 (greater than or equal to its coupon barrier level)	$7.917
Hypothetical Observation Date #2	45.00 (less than its coupon barrier level)	110.00 (greater than or equal to its coupon barrier level)	$0
Hypothetical Observation Date #3	115.00 (greater than or equal to its coupon barrier level)	125.00 (greater than or equal to its coupon barrier level)	$1,000 + $7.917 (the stated principal amount + the contingent coupon with respect to the related interest period) For more information, please see “How to determine whether the securities will be automatically redeemed with respect to a redemption determination date” above.

On hypothetical observation date #1, because the closing level of each underlier is greater than or equal to its coupon barrier level, the contingent coupon is paid on the related coupon payment date.

On hypothetical observation date #2, because the closing level of at least one underlier is less than its coupon barrier level, no contingent coupon is paid on the related coupon payment date.

On hypothetical observation date #3, the closing level of each underlier is greater than or equal to its coupon barrier level. Because the closing level of each underlier is also greater than or equal to its call threshold level, the securities are automatically redeemed for an early redemption payment equal to the stated principal amount plus the contingent coupon with respect to the related interest period. No further payments are made on the securities once they have been automatically redeemed.

If the closing level of either underlier is less than its coupon barrier level on each observation date, you will not receive any contingent coupons for the entire term of the securities.

How to calculate the payment at maturity (if the securities have not been automatically redeemed):

The hypothetical examples below illustrate how to calculate the payment at maturity if the securities have not been automatically redeemed prior to maturity.

	Final Level		Payment at Maturity per Security
	NDXT Index	SPX Index
Example #1	125.00 (greater than or equal to its downside threshold level)	115.00 (greater than or equal to its downside threshold level)	$1,000 + $7.917 (the stated principal amount + the contingent coupon with respect to the final observation date) For more information, please see “How to determine whether a contingent coupon is payable with respect to an observation date (if the securities have not been previously automatically redeemed)” above.
Example #2	45.00 (less than its downside threshold level)	110.00 (greater than or equal to its downside threshold level)	$1,000 × performance factor of the worst performing underlier = $1,000 × (45.00 / 100.00) = $450.00
Example #3	30.00 (less than its downside threshold level)	20.00 (less than its downside threshold level)	$1,000 × (20.00 / 100.00) = $200.00

In example #1, the final level of each underlier is greater than or equal to its downside threshold level. Therefore, investors receive at maturity the stated principal amount. Because the final level of each underlier is also greater than or equal to its coupon barrier level, investors receive the contingent coupon with respect to the final observation date. Investors do not participate in any appreciation of either underlier.

In examples #2 and #3, the final level of at least one underlier is less than its downside threshold level. Therefore, investors receive at maturity a payment that reflects a loss of 1% of principal for each 1% decline in the level of the worst performing underlier. Moreover, because the final level of at least one underlier is also less than its coupon barrier level, investors do not receive a contingent coupon with respect to the final observation date.

If the securities have not been automatically redeemed prior to maturity and the final level of either underlier is less than its downside threshold level, you will be exposed to the negative performance of the worst performing underlier at maturity, and your payment at maturity will be significantly less than the stated principal amount of the securities and could be zero.

Risk Factors

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

Risks Relating to an Investment in the Securities

￭The securities do not guarantee the return of any principal. The terms of the securities differ from those of ordinary debt securities in that they do not guarantee the repayment of any principal. If the securities have not been automatically redeemed prior to maturity and the final level of either underlier is less than its downside threshold level, the payout at maturity will be an amount in cash that is significantly less than the stated principal amount of each security, and you will lose an amount proportionate to the full decline in the level of the worst performing underlier over the term of the securities. There is no minimum payment at maturity on the securities, and, accordingly, you could lose your entire initial investment in the securities.

￭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 on a coupon payment date but only if the closing level of each underlier is greater than or equal to its coupon barrier level on the related observation date. However, if the closing level of either underlier is less than its coupon barrier level on any observation date, we will pay no coupon with respect to the applicable interest period. It is possible that the closing level of an underlier will remain below its coupon barrier level for extended periods of time or even throughout the entire term of the securities so that you will receive few or no contingent coupons. If you do not earn sufficient contingent coupons 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.

￭Payment of the contingent coupon is based on the closing levels of the underliers on only the related observation date at the end of the related interest period. Whether the contingent coupon will be paid on any coupon payment date will be determined at the end of the related interest period based on the closing level of each underlier on the related observation date. As a result, you will not know whether you will receive the contingent coupon on a coupon payment date until near the end of the relevant interest period. Moreover, because the contingent coupon is based solely on the closing levels of the underliers on the observation dates, if the closing level of either underlier on any observation date is less than its coupon barrier level, you will receive no coupon with respect to the related interest period, even if the closing level of such underlier was greater than or equal to its coupon barrier level on other days during that interest period and even if the closing level of the other underlier is greater than or equal to its coupon barrier level on such observation date.

￭Investors will not participate in any appreciation in the value of either underlier. Investors will not participate in any appreciation in the value of either underlier from the strike date to the final observation date, and the return on the securities will be limited to the contingent coupons that are paid with respect to the observation dates on which the closing level of each underlier is greater than or equal to its coupon barrier level. It is possible that the closing level of an underlier will remain below its coupon barrier level for extended periods of time or even throughout the entire term of the securities so that you will receive few or no contingent coupons.

￭The securities are subject to early redemption risk. The term of your investment in the securities may be shortened due to the automatic early redemption feature of the securities. If the securities are automatically redeemed prior to maturity, you will receive no further payments on the securities, 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 redeemed prior to the first redemption determination date.

￭The market price of the securities may be influenced by many unpredictable factors. Several factors, many of which are beyond our control, will influence the value of the securities in the secondary market and the price at which MS & Co. may be willing to purchase or sell the securities in the secondary market. We expect that generally the value of each underlier at any time will affect the value of the securities more than any other single factor. Other factors that may influence the value of the securities include:

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

ointerest and yield rates in the market;

othe level of correlation between the underliers;

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

othe availability of comparable instruments;

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

othe time remaining until the securities mature; and

Page 9

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

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

You can review the historical closing levels of the underliers in the section of this document called “Historical Information.” You cannot predict the future performance of an underlier based on its historical performance. The values of the underliers may be, and have recently been, volatile, and we can give you no assurance that the volatility will lessen. There can be no assurance that the closing level of each underlier will be greater than or equal to its coupon barrier level on any observation date so that you will receive a contingent coupon with respect to the applicable interest period, or that the final level of each underlier will be greater than or equal to its downside threshold level so that you do not suffer a significant loss on your initial investment in the securities.

￭The securities are subject to our credit risk, and any actual or anticipated changes to our credit ratings or credit spreads may adversely affect the market value of the securities. You are dependent on our ability to pay all amounts due on the securities, and, therefore, you are subject to our credit risk. The securities are not guaranteed by any other entity. If we default on our obligations under the securities, your investment would be at risk and you could lose some or all of your investment. As a result, the market value of the securities prior to maturity will be affected by changes in the market’s view of our creditworthiness. Any actual or anticipated decline in our credit ratings or increase in the credit spreads charged by the market for taking our credit risk is likely to adversely affect the market value of the securities.

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

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

The inclusion of the costs of issuing, selling, structuring and hedging the securities in the original issue price and the lower rate we are willing to pay as issuer make the economic terms of the securities less favorable to you than they otherwise would be.

However, because the costs associated with issuing, selling, structuring and hedging the securities are not fully deducted upon issuance, to the extent that MS & Co. may buy or sell the securities in the secondary market during the amortization period specified herein, absent changes in market conditions, including those related to the underliers, and to our secondary market credit spreads, it would do so based on values higher than the estimated value, and we expect that those higher values will also be reflected in your brokerage account statements.

￭The estimated value of the securities is determined by reference to our pricing and valuation models, which may differ from those of other dealers and is not a maximum or minimum secondary market price. These pricing and valuation models are proprietary and rely in part on subjective views of certain market inputs and certain assumptions about future events, which may prove to be incorrect. As a result, because there is no market-standard way to value these types of securities, our models may yield a higher estimated value of the securities than those generated by others, including other dealers in the market, if they attempted to value the securities. In addition, the estimated value on the pricing date does not represent a minimum or maximum price at which dealers, including MS & Co., would be willing to purchase your securities in the secondary market (if any exists) at any time. The value of your securities at any time after the date of this document will vary based on many factors that cannot be predicted with accuracy, including our creditworthiness and changes in market conditions. See also “The market price of the securities may be influenced by many unpredictable factors” above.

￭The securities will not be listed on any securities exchange and secondary trading may be limited. The securities will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the securities. MS & Co. may, but is not obligated to, make a market in the securities and, if it once chooses to make a market, may cease doing so at any time. When it does make a market, it will generally do so for transactions of routine secondary market size at prices based on its estimate of the current value of the securities, taking into account its bid/offer spread, our credit spreads, market volatility, the notional size of the proposed sale, the cost of unwinding any related hedging positions, the time remaining to maturity and the likelihood that it will be able to resell the securities. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the securities easily. Since other broker-dealers may not participate significantly in the secondary market for the securities, the price at which you may be able to trade your securities is likely to depend on the price, if any, at which MS & Co. is willing to transact. If, at any time, MS & Co. were to cease making a market in the securities, it is likely that there would be no secondary market for the securities. Accordingly, you should be willing to hold your securities to maturity.

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

￭The U.S. federal income tax consequences of an investment in the securities are uncertain. There is no direct legal authority regarding the proper U.S. federal income tax treatment of the securities, and significant aspects of the tax treatment of the securities are uncertain. Moreover, non-U.S. investors should note that persons having withholding responsibility in respect of the securities 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 Income Tax Considerations” in the accompanying product supplement, and consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the securities.

Risks Relating to the Underlier(s)

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

oYou are exposed to the price risk of each underlier.

oBecause the securities are linked to the performance of the worst performing underlier, you are exposed to a greater risk of not receiving a positive return on the securities and/or sustaining a significant loss on your investment than if the securities were linked to just one underlier.

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

￭The securities are subject to risks associated with investments in securities with a concentration in the technology sector. The securities constituting the Nasdaq-100® Technology Sector IndexSM are those of companies whose primary business is directly associated with the technology sector, including the following sub-sectors: computers and peripherals, software, diversified telecommunication services, communications equipment, semiconductors and semiconductor equipment, internet software and services, IT services, electronic equipment, instruments and components, wireless telecommunication services and office electronics.

The values of securities of technology companies and companies that rely heavily on technology are particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Technology companies and companies that rely heavily on technology, especially those that are smaller or less-seasoned, tend to be more volatile than the overall market. Additionally, companies in the technology sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel. All of these factors could have an effect on the value of the Nasdaq-100® Technology Sector IndexSM, and, therefore, the value of the securities.

Risks Relating to Conflicts of Interest

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

￭The calculation agent, which is a subsidiary of Morgan Stanley and an affiliate of MSFL, will make determinations with respect to the securities. As calculation agent, MS & Co. will make any determinations necessary to calculate any payment(s) on the securities. Moreover, certain determinations made by MS & Co., in its capacity as calculation agent, may require it to exercise discretion and make subjective judgments, which may adversely affect your return on the securities. In addition, MS & Co. has determined the estimated value of the securities on the pricing date.

￭Hedging and trading activity by our affiliates could potentially adversely affect the value of the securities.

Additional Information About the Securities

Additional Information:
Minimum ticketing size:	$1,000 / 1 security
United States federal income tax considerations:	You should review carefully the section in the accompanying product supplement entitled “United States Federal Income Tax Considerations.” The following discussion, when read in combination with 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. Generally, this discussion assumes that you purchased the securities for cash in the original issuance at the stated issue price and does not address other circumstances specific to you, including consequences that may arise due to any other investments relating to an underlier. You should consult your tax adviser regarding the effect any such circumstances may have on the U.S. federal income tax consequences of your ownership of a security. 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 Income Tax Considerations—Tax Consequences to U.S. Holders—Securities Treated as Prepaid Financial Contracts with Associated Coupons” in the accompanying product supplement. There is uncertainty regarding this treatment, and 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, there is a risk that the securities could be characterized as debt instruments for U.S. federal income tax purposes, in which case the tax consequences of an investment in the securities could be different from those described herein and possibly adverse to certain investors. In addition, the U.S. Treasury Department and the IRS have requested comments on various issues regarding the U.S. federal income tax treatment of “prepaid forward contracts” and similar financial instruments and have indicated that such transactions may be the subject of future regulations or other guidance. Furthermore, members of Congress have proposed legislative changes to the tax treatment of derivative contracts. Any legislation, Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, possibly with retroactive effect. Non-U.S. Holders. 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 defined in the accompanying product supplement) 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 Income Tax Considerations—Tax Consequences to Non-U.S. Holders—Dividend Equivalents under Section 871(m) of the Code” in the accompanying product supplement, Section 871(m) of the Internal Revenue Code and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% withholding tax on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities. The Treasury regulations, as modified by an IRS notice, exempt financial instruments issued prior to January 1, 2027 that do not have a “delta” of one. Based on certain 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.
Additional considerations:	Client accounts over which Morgan Stanley, Morgan Stanley Wealth Management or any of their respective subsidiaries have investment discretion are not permitted to purchase the securities, either directly or indirectly.

Annex A—Nasdaq-100® Technology Sector IndexSM

The Nasdaq-100® Technology Sector IndexSM (the “NDXT Index”), which was first published on February 22, 2006 with a base value of 1,000, is an equal weighted index based on the securities of the Nasdaq-100 Index® (the “parent index”) that are classified as a Technology Company under the Industry Classification Benchmark (ICB) classification system. The parent index is designed to measure the performance of 100 of the largest and most actively traded equity securities of non-financial companies listed on The Nasdaq Stock Market LLC (“Nasdaq”). For more information about the parent index, see “Nasdaq-100 Index®” in the accompanying index supplement. The NDXT Index is calculated, maintained and published by Nasdaq. The NDXT Index is reported by Bloomberg Financial Markets under ticker symbol “NDXT.”

Security Eligibility Criteria. A security must be a component of the Nasdaq-100 Index® in order to be eligible for inclusion in the NDXT Index. For more information about the security eligibility criteria for the Nasdaq-100 Index® and thereby the NDXT Index, see “Nasdaq-100 Index®—Security Eligibility Criteria” in the accompanying index supplement.

Reconstitution and Rebalancing. The NDXT Index follows the same reconstitution and rebalancing schedule as the parent index. Index rebalance changes are based on the last sale prices as of the close of trading on the third Friday of each March, June, September and December. For more information, see “Nasdaq-100 Index®—Reconstitution and Rebalancing of the Nasdaq-100 Index® in the accompanying index supplement.

Constituent Selection. Any security that is a component of the Nasdaq-100 Index® and is classified as a Technology Company according to the ICB is a constituent of the NDXT Index. If a component of the NDXT Index is removed from the Nasdaq-100 Index® for any reason, it is removed from the NDXT Index at the same time. For more information about constituent selection, see “Nasdaq-100 Index®—Constituent Selection” in the accompanying index supplement.

Constituent Weighting. The NDXT Index is an equal-weighted index. The NDXT Index is rebalanced quarterly such that all index components are assigned an equal Index Security Market Value. Index Security Market Value is calculated as follows:

Index Security Market Valuet = qi,t × pi,t × Spot ratei,t

where,

𝑞𝑖 = Number of shares of Index Security i applied in the NDXT Index. The number of shares can be based on any number of items which would be identified in each specific Index Methodology including total shares outstanding (TSO), application of free float, dividend yield, modification due to foreign ownership restrictions, modification due to capping etc. This can also be referred to as Index Shares.

𝑝𝑖 = Price in quote currency of Index Security i. Depending on the time of the calculation, the price can be either of the following:

1.The Start of Day (SOD) price which is the previous index calculation day’s (t-1) closing price for Index Security i adjusted for corporate action(s) occurring prior to market open on date t, if any, for the SOD calculation only;

2.The intraday price which reflects the current trading price received from the Index Exchange during the index calculation day;

3.The End of Day (EOD) price refers to the Last Sale Price; or

4.The Volume Weighted Average Price (VWAP)

Spot ratei = Foreign exchange rate to convert Index Security i quote currency into Index Currency. Foreign exchange rate is provided by the WM Company1 and in the calculation of the EOD Index Value is the closing spot rate at 16:00:00 UK time, unless otherwise noted in the Index Methodology. Intraday spot rates are applied to the real time index calculations during the index calculation day. The Index Security Market Value at SOD utilizes Spot ratei,t -1

t = current index calculation day

t – 1 = previous index calculation day

For issuers represented by multiple securities included in the NDXT Index, those issuers’ Index Security Market Values are equally dispersed across their respective index components. Index Shares are calculated by dividing each Index Security’s resulting Index market value by its Last Sale Price.

Index Maintenance.

Deletion Policy. When a component of the NDXT Index is removed from the Nasdaq-100 Index® for any reason, it is removed from the NDXT Index at the same time. For more information about the deletion policy for the Nasdaq-100 Index®, see “Nasdaq-100 Index®—Index Maintenance—Deletion Policy” in the accompanying index supplement.

Replacement Policy. If the replacement company for a component removed from the Nasdaq-100 Index® and therefore the NDXT Index is classified as a Technology Company according to the ICB, it will be added to the NDXT Index at the same time and will assume the same weight of the removed company. For more information on the replacement policy for the Nasdaq-100 Index®, see “Nasdaq-100 Index®—Index Maintenance—Replacement Policy” in the accompanying index supplement.

When a component of the Nasdaq-100 Index® that is not classified as a Technology Company according to the ICB is removed from the Nasdaq-100 Index® and replaced in the Nasdaq-100 Index® by a component that is classified as a Technology Company according to the ICB, such replacement company will be considered for addition to the NDXT Index at the next quarterly rebalance.

When a component of the Nasdaq-100 Index® that is classified as a Technology Company according to the ICB is removed from the Nasdaq-100 Index® and replaced in the Nasdaq-100 Index® by a component that is not classified as a Technology Company according to the ICB, such replacement company is not added to the NDXT Index and the divisor of the NDXT Index is adjusted for continuity.

Corporate Actions. In the periods between scheduled index reconstitution and rebalancing events, individual index securities may be subject to a variety of corporate actions and events that require maintenance and adjustments to the NDXT Index.

Additions Policy. If a security that is classified as a Technology Company according to the ICB is added to the Nasdaq-100 Index® for any reason, it may be added to the NDXT Index at the same time.

Governance of the NDXT Index. The Nasdaq Index Management Committee approves all new index methodologies. This committee is comprised of full-time professional members of Nasdaq. The committee meets regularly and reviews items including, but not limited to, pending corporate actions that may affect NDXT Index constituents, statistics comparing the composition of the NDXT Index to the market, companies that are being considered as candidates for addition to the NDXT Index and any significant market events.
