Based on the Performance of a Basket

Buffered Performance Leveraged Upside Securities SM

Fully and Unconditionally Guaranteed by Morgan Stanley

Principal at Risk Securities

￭The Buffered PLUS (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 and have the terms described in the accompanying product supplement, index supplement and prospectus, as supplemented or modified by this document.

￭Payment at maturity. At maturity, if the final level is greater than the initial level, investors will receive the stated principal amount plus the leveraged upside payment, subject to the maximum payment at maturity. If the final level is equal to or less than the initial level but is greater than or equal to the buffer level, investors will receive only the stated principal amount at maturity. If, however, the final level is less than the buffer level, investors will lose 1% for every 1% decline in the level of the underlier beyond the specified buffer amount. Under these circumstances, the payment at maturity will be less, and may be significantly less, than the stated principal amount of the securities, subject to the minimum payment at maturity.

￭The securities are for investors who seek a return based on the performance of the underlier and who are willing to risk their principal and forgo current income and returns above the maximum payment at maturity in exchange for the upside leverage feature and the buffer feature that applies to any negative performance of the underlier over the term of the securities. Investors in the securities must be willing to accept the risk of losing a significant portion of their initial investment. 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 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.

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 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, 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 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.

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

Hypothetical Payoff Diagram

The payoff diagram below illustrates the payment at maturity for a range of hypothetical performances of the underlier over the term of the securities, based on the following terms:

Stated principal amount: | $1,000 per security
Leverage factor: | 150%
Maximum payment at maturity: | $1,250 per security (125% of the stated principal amount)
Buffer level: | 95% of the initial level
Buffer amount: | 5%
Minimum payment at maturity: | 5% of the stated principal amount
Hypothetical Payoff Diagram |

￭Upside Scenario. If the final level is greater than the initial level, investors will receive the stated principal amount plus 150% of the appreciation of the underlier over the term of the securities, subject to the maximum payment at maturity.

o If the underlier appreciates 10%, investors will receive $1,150 per security, or 115% of the stated principal amount.

o If the underlier appreciates 100%, investors will receive only the maximum payment at maturity of $1,250 per security, or 125% of the stated principal amount.

￭Par Scenario. If the final level is equal to or less than the initial level but is greater than or equal to the buffer level, investors will receive the stated principal amount.

o If the underlier depreciates 3%, investors will receive $1,000 per security.

￭Downside Scenario. If the final level is less than the buffer level, investors will receive an amount that is less, and may be significantly less, than the stated principal amount, based on a 1% loss of principal for each 1% decline in the level of the underlier beyond the buffer amount.

o If the underlier depreciates 85%, investors will lose 80% of their principal and receive only $200 per security at maturity, or 20% of the stated principal amount.

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 provide for only the minimum payment at maturity and do not pay interest. The terms of the securities differ from those of ordinary debt securities in that they provide for only the minimum payment at maturity and do not pay interest. If the final level is less than the buffer level, the payout at maturity will be an amount in cash that is 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 underlier over the term of the securities beyond the buffer amount. You could lose a significant portion of your initial investment in the securities.

￭The appreciation potential of the securities is limited by the maximum payment at maturity. Where the final level is greater than the initial level, the appreciation potential of the securities is limited by the maximum payment at maturity. Although the leverage factor provides enhanced exposure to any increase in the final level over the initial level, if the underlier appreciates over the term of the securities, under no circumstances will the payment at maturity exceed the maximum payment at maturity.

￭The amount payable on the securities is not linked to the value of the underlier at any time other than the observation date. The final level will be based on the closing level of the underlier on the observation date, subject to postponement for non-trading days and certain market disruption events. Even if the value of the underlier appreciates prior to the observation date but then drops by the observation date, the payment at maturity may be less, and may be significantly less, than it would have been had the payment at maturity been linked to the value of the underlier prior to such drop. Although the actual value of the underlier on the stated maturity date or at other times during the term of the securities may be higher than the closing level of the underlier on the observation date, the payment at maturity will be based solely on the closing level of the underlier on the observation 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 the basket components 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:

o the volatility (frequency and magnitude of changes in value) of the underlier;

o interest and yield rates in the market;

o dividend rates on a basket fund;

o the relative performance of each basket component;

o geopolitical conditions and economic, financial, political, regulatory or judicial events that affect the basket components or equity markets generally;

o the availability of comparable instruments;

o the occurrence of certain events affecting a basket fund that may or may not require an adjustment to an adjustment factor;

o the composition of a basket component and changes in the component securities of a basket component;

o the time remaining until the securities mature; and

o any 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 the underlier is at, below or not sufficiently above the buffer level, or if market interest rates rise.

You can review the historical basket component closing levels of the basket components in the section of this document called “Historical Information.” You cannot predict the future performance of the underlier based on its historical performance. The values of the basket components 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 final level will be greater than or equal to the buffer level so that you do not suffer a 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.

Buffered PLUS Principal at Risk Securities

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 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 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 basket components.

￭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, the securities may be subject to the “constructive ownership” regime, in which case certain adverse tax consequences may apply upon your disposition of a security. 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

Page 6

Morgan Stanley Finance LLC

Buffered PLUS Principal at Risk Securities

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.

o Changes in the value of one or more of the basket components may offset each other.

o The anti-dilution adjustments the calculation agent is required to make do not cover every event that could affect a basket fund.

o Adjustments to a basket fund or the index tracked by such basket fund could adversely affect the value of the securities.

o The performance and market price of a basket fund, particularly during periods of market volatility, may not correlate with the performance of its share underlying index, the performance of the component securities of its share underlying index or the net asset value per share of such basket fund.

o Adjustments to a basket index could adversely affect the value of the securities.

o There are risks associated with investments in securities linked to the value of foreign equity securities.

o There are risks associated with investments in securities linked to the value of emerging markets securities.

o Securities linked to certain underliers are subject to currency exchange risk.

￭The securities are subject to risks associated with small-capitalization companies. The Russell 2000® Index consists of stocks issued by companies with relatively small market capitalization. These companies often have greater stock price volatility, lower trading volume and less liquidity than large-capitalization companies and therefore the Russell 2000® Index may be more volatile than indices that consist of stocks issued by large-capitalization companies. Stock prices of small-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business and economic developments, and the stocks of small-capitalization companies may be thinly traded. In addition, small capitalization companies are typically less well-established and less stable financially than large-capitalization companies and may depend on a small number of key personnel, making them more vulnerable to loss of personnel. Such companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and less competitive strengths than large-capitalization companies and are more susceptible to adverse developments related to their products.

￭The securities are subject to risks associated with mid-capitalization companies. The S&P MidCap 400® Index consists of stocks issued by companies that are considered mid-capitalization companies. These companies often have greater stock price volatility, lower trading volume and less liquidity than large-capitalization companies and therefore the S&P MidCap 400® Index may be more volatile than indices that consist of stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business and economic developments. In addition, mid-capitalization companies are typically less well-established and less stable financially than large-capitalization companies and may depend on a small number of key personnel, making them more vulnerable to loss of personnel. Such companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and less competitive strengths than large-capitalization companies and are more susceptible to adverse developments related to their products.

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.

Historical Information

Underlier Overview

The underlier is an underlying basket consisting of the basket components. The weighting of each basket component within the underlier is specified on the cover of this document. The actual performance of the underlier and the basket components over the term of the securities may bear little relation to the historical performance of the underlier and the basket components presented in this document.

The following graph is calculated based on an initial level of the underlier of 100 on January 1, 2020 (assuming that each basket component is weighted as described in “Underlier” on the cover of this document) and illustrates the effect of the offset and/or correlation among the basket components during such period. The following graph does not take into account the terms of the securities, nor does it attempt to show in any way your expected return on an investment in the securities. The historical performance of the underlier should not be taken as an indication of its future performance.

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 that are “open transactions,” as described in the section entitled “United States Federal Income Tax Considerations—Tax Consequences to U.S. Holders—Securities Treated as Prepaid Financial Contracts that are Open Transactions” 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. Generally, if this treatment is respected, subject to the potential application of the “constructive ownership” regime discussed below, (i) you should not recognize taxable income or loss prior to the taxable disposition of your securities (including upon maturity or an earlier redemption, if applicable) and (ii) the gain or loss on your securities should be treated as capital gain or loss. Even if the treatment of the securities as prepaid financial contracts is respected, purchasing a security could be treated as entering into a “constructive ownership transaction” within the meaning of Section 1260 of the Internal Revenue Code (“Section 1260”), as described in the sections entitled “United States Federal Income Tax Considerations—Tax Consequences to U.S. Holders—Securities Treated as Prepaid Financial Contracts that are Open Transactions—Possible Application of Section 1260 of the Code” in the accompanying product supplement. Due to the lack of direct legal authority, our counsel is unable to opine as to whether or how Section 1260 applies to the securities. 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 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. 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 and the potential application of the “constructive ownership” regime, 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.
Supplemental information regarding plan of distribution; | MS & Co. expects to sell all of the securities that it purchases from us to an unaffiliated dealer at a price of $1,000 per security, for further sale to certain fee-based advisory accounts at the price to

Validity of the securities: | In the opinion of Davis Polk & Wardwell LLP, as special counsel to MSFL and Morgan Stanley, when the securities offered by this pricing supplement have been issued by MSFL pursuant to the MSFL Senior Debt Indenture (as defined in the accompanying prospectus), the trustee and/or paying agent has made, in accordance with the instructions from MSFL, the appropriate entries or notations in its records relating to the master note that represents such securities (the “master note”), and such securities have been delivered against payment as contemplated herein, such securities will be valid and binding obligations of MSFL and the related guarantee will be a valid and binding obligation of Morgan Stanley, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability (including, without limitation, concepts of good faith, fair dealing and the lack of bad faith), provided that such counsel expresses no opinion as to (i) the effect of fraudulent conveyance, fraudulent transfer or similar provision of applicable law on the conclusions expressed above and (ii) any provision of the MSFL Senior Debt Indenture that purports to avoid the effect of fraudulent conveyance, fraudulent transfer or similar provision of applicable law by limiting the amount of Morgan Stanley’s obligation under the related guarantee. This opinion is given as of the date hereof and is limited to the laws of the State of New York, the General Corporation Law of the State of Delaware and the Delaware Limited Liability Company Act. In addition, this opinion is subject to customary assumptions about the trustee’s authorization, execution and delivery of the MSFL Senior Debt Indenture and its authentication of the master note and the validity, binding nature and enforceability of the MSFL Senior Debt Indenture with respect to the trustee, all as stated in the letter of such counsel dated September 23, 2025, which was filed as an exhibit to a Current Report on Form 8-K by the Company on September 23, 2025.
