Fixed to Floating Rate Callable Notes due August 27, 2040

10-Year Constant Maturity Treasury Rate-Linked Range Accrual Notes

Fully and Unconditionally Guaranteed by Morgan Stanley

As further described below, we, Morgan Stanley Finance LLC (“MSFL”), will redeem the notes in accordance with the risk neutral valuation model determination noted herein. Any redemption payment will be at a redemption price equal to 100% of the principal amount to be redeemed, plus accrued and unpaid interest thereon to but excluding the redemption date.

Subject to the call feature, interest will accrue and be payable on the notes quarterly, in arrears, (i) from the original issue date to August 27, 2028: at a rate of 9.00% per annum and (ii) from August 27, 2028 to maturity: at a variable rate equal to 9.00% per annum for each calendar day that the 10-Year Constant Maturity Treasury Rate (“10CMT”) is greater than or equal to 0.00% and less than or equal to 5.00% (which we refer to as the reference rate range). Consequently, if, on any day, the level of 10CMT is not within the reference rate range, no interest will accrue for such day. These long-dated notes are for investors who seek an opportunity to earn interest at a potentially above-market rate in exchange for the risk of receiving little or no interest on the notes with respect to any day during the floating interest rate period on which the condition listed above is not met.

For further discussion of risks related to the notes, including risks related to the reference rate, see “Risk Factors” beginning on page 7.

All payments are subject to our credit risk. If we default on our obligations, you could lose some or all of your investment. These notes 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.

The Notes

The notes offered are debt securities of Morgan Stanley Finance LLC (“MSFL”) and are fully and unconditionally guaranteed by Morgan Stanley. As further described below, interest will accrue and be payable on the notes quarterly, in arrears, (i) from the original issue date to August 27, 2028: at a rate of 9.00% per annum and (ii) from August 27, 2028 to maturity: at a variable rate equal to 9.00% per annum for each calendar day that 10CMT is greater than or equal to 0.00% and less than or equal to 5.00% (which we refer to as the reference rate range). Consequently, if, on any day, the level of 10CMT is not within the reference rate range, no interest will accrue for such day. These long-dated notes are for investors who seek an opportunity to earn interest at a potentially above-market rate in exchange for the risk of receiving little or no interest on the notes with respect to any day during the floating interest rate period on which 10CMT is not within the reference rate range. Investors must be willing and able to forgo interest for significant periods of time, including possibly the entire floating interest rate period.

Beginning on the initial redemption date, an early redemption, in whole but not in part, will occur on a redemption date if and only if the output of a risk neutral valuation model on a business day that is at least five but no more than eight business days prior to such redemption date, based on the inputs indicated in the call feature terms, indicates that redeeming on such date is economically rational for us as compared to not redeeming on such date. Any redemption payment will be at a redemption price equal to 100% of the principal amount to be redeemed, plus accrued and unpaid interest thereon to but excluding the redemption date. If we call the notes, we will give you notice at least five business days before the call date specified in the notice. On or before the redemption date, we will deposit with the trustee money sufficient to pay the redemption price of and accrued interest on the notes to be redeemed on that date. If such money is so deposited, on and after the redemption date, interest will cease to accrue on the notes (unless we default in the payment of the redemption price and accrued interest) and such notes will cease to be outstanding. We describe the basic features of these notes in the sections of the accompanying prospectus called “Description of Debt Securities—Floating Rate Debt Securities” and prospectus supplement called “Description of Notes,” subject to and as modified by the provisions described below. For information regarding notices of redemption, see “Description of Debt Securities—Redemption and Repurchase of Debt Securities—Notice of Redemption” in the accompanying prospectus. All payments on the notes are subject to our credit risk.

The stated principal amount and issue price of each note is $1,000. This price includes costs associated with issuing, selling, structuring and hedging the notes, which are borne by you, and, consequently, the estimated value of the notes on the pricing date is less than the issue price. We estimate that the value of each note on the pricing date is $911.30.

What goes into the estimated value on the pricing date?

In valuing the notes on the pricing date, we take into account that the notes comprise both a debt component and a performance-based component linked to 10CMT. The estimated value of the notes is determined using our own pricing and valuation models, market inputs and assumptions relating to 10CMT, instruments based on 10CMT, 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 notes?

In determining the economic terms of the notes, including the interest rate and the reference rate range, 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 notes 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 notes?

The price at which MS & Co. purchases the notes in the secondary market, absent changes in market conditions, including those related to interest rates and 10CMT, 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, the costs of unwinding the related hedging transactions and other factors.

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

How the Notes Work

The table below presents examples of hypothetical interest rates at which interest would accrue on the notes during any year during the floating interest rate period based on the total number of calendar days in a quarterly interest payment period on which 10CMT is within the reference rate range. The table assumes that the interest payment period contains 90 calendar days.

The example below is for purposes of illustration only and would provide different results if different assumptions were made. The actual quarterly interest payments during the floating interest rate period will depend on the actual number of calendar days in each interest payment period and the actual level of 10CMT on each day. The applicable interest rate for each quarterly interest payment period during the floating interest rate period will be determined on a per-annum basis but will apply only to that interest payment period.


N	Annualized Rate of Interest Paid
0	0.0000%
15	1.5000%
30	3.0000%
45	4.5000%
60	6.0000%
75	7.5000%
90	9.0000%

Beginning August 27, 2028, it is possible that you could receive little or no interest on the notes. If, on any calendar day during the floating interest rate period, 10CMT is not within the reference rate range, interest will accrue at a rate of 0.00% per annum for that day.

Risk Factors

The notes involve risks not associated with an investment in ordinary floating rate notes. This section describes the material risks relating to the notes. For a complete list of risk factors, please see the accompanying prospectus supplement and prospectus. Investors should consult their financial and legal advisers as to the risks entailed by an investment in the notes and the suitability of the notes in light of their particular circumstances.

Risks Relating to an Investment in the Notes

￭The notes have early redemption risk. Beginning on the initial redemption date, an early redemption, in whole but not in part, will occur on a redemption date if and only if the output of a risk neutral valuation model on a business day that is at least five but no more than eight business days prior to such redemption date, based on the inputs indicated in the call feature terms, indicates that redeeming on such date is economically rational for us as compared to not redeeming on such date. In accordance with the risk neutral valuation model determination noted herein, it is more likely that the issuer will redeem the notes prior to their stated maturity date to the extent that the interest payable on the notes is greater than the interest that would be payable on other instruments of the issuer of a comparable maturity, of comparable terms and of a comparable credit rating trading in the market. If the notes are redeemed prior to their stated maturity date, you will receive no further interest payments on the redeemed notes and may have to re-invest the proceeds in a lower interest rate environment.

￭If there are no accrual days in any interest payment period during the floating interest rate period, we will not pay any interest on the notes for that interest payment period and the market value of the notes may decrease significantly. It is possible that 10CMT will not be within the reference rate range for so many days during any quarterly interest payment period during the floating interest rate period that the interest payment for that quarterly interest payment period will be less than the amount that would be paid on an ordinary debt security and may be zero. To the extent that 10CMT is not within the reference rate range during the term of the notes, the market value of the notes may decrease, and you may receive substantially less than 100% of the issue price if you are able to sell your notes at such time.

￭For purposes of determining the level of 10CMT, the level of reference rate for any day from and including the fifth U.S. government securities business day prior to the interest payment date of an interest payment period shall be the level of the reference rate with respect to such fifth day. Because the level of the reference rate for any day from and including the fifth U.S. government securities business day prior to the interest payment date of an interest payment period during the floating interest rate period shall be the level of the reference rate with respect to such fifth day, if with respect to such fifth day 10CMT is not within the reference rate range, you will not receive any interest in respect of any days on or after that fifth business day to but excluding the interest payment date even if any of those days would have been an accrual day were the levels of 10CMT determined based on the actual reference rate with respect to such day.

￭The historical performance of 10CMT is not an indication of future performance. The historical performance of 10CMT should not be taken as an indication of future performance during the term of the notes. Changes in the level of 10CMT will affect the trading price of the notes, but it is impossible to predict whether such level will rise or fall. There can be no assurance that 10CMT will be within the reference rate range on any day during the floating interest rate period so that interest will accrue for such day.

￭Investors 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 notes. Investors are dependent on our ability to pay all amounts due on the notes on interest payment dates, on redemption dates and at maturity and therefore investors are subject to our credit risk and to changes in the market’s view of our creditworthiness. If we default on our obligations under the notes, your investment would be at risk and you could lose some or all of your investment. As a result, the market value of the notes 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 value of the notes.

￭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

August 2025 Page 7

Morgan Stanley Finance LLC

Fixed to Floating Rate Callable Notes due August 27, 2040

10-Year Constant Maturity Treasury Rate-Linked Range Accrual Notes

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 price at which the notes may be sold prior to maturity will depend on a number of factors and may be substantially less than the amount for which they were originally purchased. Some of these factors include, but are not limited to: (i) actual or anticipated changes in the level of the reference rate, (ii) volatility of the level of the reference rate, (iii) changes in interest and yield rates, (iv) any actual or anticipated changes in our credit ratings or credit spreads and (v) time remaining to maturity. Generally, the longer the time remaining to maturity and the more tailored the exposure, the more the market price of the notes will be affected by the other factors described in the preceding sentence. This can lead to significant adverse changes in the market price of securities like the notes. Depending on the actual or anticipated level of the reference rate and interest and yield rates, the market value of the notes is expected to decrease and you may receive substantially less than 100% of the issue price if you are able to sell your notes prior to maturity.

￭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 notes in the original issue price reduce the economic terms of the notes, cause the estimated value of the notes 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., are willing to purchase the notes 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, the costs of unwinding the related hedging transactions as well as other factors.

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

￭The estimated value of the notes 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 notes than those generated by others, including other dealers in the market, if they attempted to value the notes. 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 notes in the secondary market (if any exists) at any time. The value of your notes at any time after the date of this pricing supplement will vary based on many factors that cannot be predicted with accuracy, including our creditworthiness and changes in market conditions.

￭The notes will not be listed on any securities exchange and secondary trading may be limited. The notes will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the notes. MS & Co. may, but is not obligated to, make a market in the notes 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 notes, 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 notes. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the notes easily. Since other broker-dealers may not participate significantly in the secondary market for the notes, the price at which you may be able to trade your notes 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 notes, it is likely that there would be no secondary market for the notes. Moreover, in accordance with the risk neutral valuation model determination noted herein, it is less likely that the issuer will redeem the notes prior to their stated maturity date to the extent that the interest payable on the notes is less than the interest that would be payable on other instruments of the issuer of a comparable maturity trading in the market. Accordingly, you should be willing to hold your notes to maturity.

￭Morgan Stanley & Co. LLC, which is a subsidiary of Morgan Stanley and an affiliate of MSFL, has determined the estimated value on the pricing date. MS & Co. has determined the estimated value of the notes on the pricing date.

￭Our affiliates may publish research that could affect the market value of the notes. They also expect to hedge the issuer’s obligations under the notes. One or more of our affiliates may, at present or in the future, publish research reports with respect to movements in interest rates generally or the reference rate specifically. This research is modified from time to time without notice to you and may express opinions or provide recommendations that are inconsistent with purchasing or holding the notes. Any of these activities may affect the market value of the notes. In addition, our affiliates expect to hedge the issuer’s obligations under the notes and they may realize a profit from that expected hedging activity even if investors do not receive a favorable investment return under the terms of the notes or in any secondary market transaction.

￭The calculation agent, which is a subsidiary of Morgan Stanley and an affiliate of MSFL, will make determinations with respect to the notes. Any of these determinations made by the calculation agent may adversely affect the payout to investors. Moreover, certain determinations made by the calculation agent may require it to exercise discretion and make subjective judgments, such as with respect to the reference rate. These potentially subjective determinations may adversely affect the payout to you on the notes. For further information regarding these types of determinations, see “Description of Debt Securities―Base Rates—CMT Rate Debt Securities” and related definitions in the accompanying prospectus, subject to and as modified by the provisions described in “Additional Provisions—Reference Rate” above.

Risks Relating to the Reference Rate

￭The reference rate will be affected by a number of factors. A number of factors can affect the reference rate, including, but not limited to:

￭sentiment regarding the U.S. and global economies;

￭expectations regarding the level of price inflation;

￭sentiment regarding credit quality in the U.S. and global credit markets;

￭central bank policy regarding interest rates;

￭inflation and expectations concerning inflation; and

￭performance of capital markets.

These and other factors may have a negative impact on the amount of interest payable on the notes and on the value of the notes prior to maturity.

￭The reference rate and the manner in which it is calculated may change in the future. There can be no assurance that the method by which the reference rate is calculated will continue in its current form. The reference rate may be altered or discontinued or the calculation or dissemination of the reference rate may be suspended. No person has any obligation to consider your interests in calculating, adjusting, converting, revising or discontinuing the reference rate. Any of these events could reduce the reference rate and may have a negative impact on the amount of interest payable on the notes and on the value of the notes prior to maturity.

Use of Proceeds and Hedging

The proceeds from the sale of the notes will be used by us for general corporate purposes. We will receive, in aggregate, $1,000 per note issued, because, when we enter into hedging transactions in order to meet our obligations under the notes, our hedging counterparty will reimburse the cost of the Agent’s commissions. The costs of the notes borne by you and described beginning on page 3 above comprise the Agent’s commissions and the cost of issuing, structuring and hedging the notes.

Supplemental Information Concerning Plan of Distribution; Conflicts of Interest

Morgan Stanley or one of our affiliates will pay varying discounts and commissions to dealers, including Morgan Stanley Smith Barney LLC (“Morgan Stanley Wealth Management”) and their financial advisors, of up to $25 per note depending on market conditions. The agent may distribute the notes through Morgan Stanley Wealth Management, as selected dealer, or other dealers, which may include Morgan Stanley & Co. International plc (“MSIP”) and Bank Morgan Stanley AG. Morgan Stanley Wealth Management, MSIP and Bank Morgan Stanley AG are affiliates of ours.

MS & Co. is an affiliate of MSFL and a wholly owned subsidiary of Morgan Stanley, and it and other affiliates of ours expect to make a profit by selling, structuring and, when applicable, hedging the notes.

MS & Co. will conduct this offering in compliance with the requirements of FINRA Rule 5121 of the Financial Industry Regulatory Authority, Inc., which is commonly referred to as FINRA, regarding a FINRA member firm’s distribution of the securities of an affiliate and related conflicts of interest. MS & Co. or any of our other affiliates may not make sales in this offering to any discretionary account.

Acceleration Amount in Case of an Event of Default

In case an event of default with respect to the notes shall have occurred and be continuing, the amount declared due and payable per note upon any acceleration of the notes shall be an amount in cash equal to the stated principal amount plus accrued and unpaid interest.

Validity of the Notes

In the opinion of Davis Polk & Wardwell LLP, as special counsel to MSFL and Morgan Stanley, when the notes offered by this pricing supplement have been executed and issued by MSFL, authenticated by the trustee pursuant to the MSFL Senior Debt Indenture (as defined in the accompanying prospectus) and delivered against payment as contemplated herein, such notes 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 notes 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 February 26, 2024, which is Exhibit 5-a to Post-Effective Amendment No. 2 to the Registration Statement on Form S-3 filed by Morgan Stanley on February 26, 2024.

Tax Considerations

The notes should be treated as “contingent payment debt instruments” for U.S. federal tax purposes, as described in the section of the accompanying prospectus supplement called “United States Federal Taxation—Tax Consequences to U.S. Holders—Contingent Payment Notes.” Under this treatment, U.S. taxable investors generally would be subject to annual income tax based on the “comparable yield” (as defined in the accompanying prospectus supplement) of the notes, adjusted upward or downward to reflect the difference, if any, between the actual and the projected amount of any contingent payments on the notes.
