GLOBAL MEDIUM-TERM NOTES, SERIES F

Fixed Rate Reset Subordinated Notes Due 2039

We, Morgan Stanley, are offering the Global Medium-Term Notes, Series F, Fixed Rate Reset Subordinated Notes Due 2039 (the “notes”) described below on a global basis. We may redeem the notes, (i) in whole but not in part, on February , 2034, or (ii) in whole at any time or in part from time to time, on or after August , 2038, in each case at a redemption price equal to 100% of the principal amount to be redeemed plus accrued and unpaid interest thereon (calculated as described below) to but excluding the redemption date, in accordance with the provisions described in the accompanying prospectus under the heading “Description of Debt Securities—Redemption and Repurchase of Debt Securities—Notice of Redemption,” as supplemented by the provisions below under the heading “Optional Redemption.” Any early redemption of the notes will be subject to the approval of the Board of Governors of the Federal Reserve System (the “Federal Reserve”), if then required under capital guidelines applicable to us. In addition, under such regulations, prior to redeeming the notes, or immediately thereafter, we will be required to either replace the redeemed notes with an equivalent amount of a financial instrument that meets the regulatory capital criteria of the Federal Reserve or demonstrate to the satisfaction of the Federal Reserve that, following redemption, we would continue to hold an amount of capital that is commensurate with our risk.

We will issue the notes only in registered form, which form is further described under “Description of Notes—Forms of Notes” in the accompanying prospectus supplement.

We describe the basic features of the notes in the section of the accompanying prospectus supplement called “Description of Notes” and in the section of the accompanying prospectus called “Description of Debt Securities—Subordination Provisions,” in each case subject to and as modified by the provisions described below. In addition, we describe the basic features of the notes during the Initial Fixed Rate Period (as defined below) in the section of the accompanying prospectus called “Description of Debt Securities—Fixed Rate Debt Securities,” subject to and as modified by the provisions described below. The interest rate will reset once during the term of the notes and we describe the basic features of the notes during the Subsequent Fixed Rate Period (as defined below) in the section of this pricing supplement called “Description of Debt Securities—Fixed Rate Reset Debt Securities,” as supplemented by the provisions described elsewhere in this pricing supplement.

We describe how interest is calculated, accrued and paid during the Initial Fixed Rate Period, including where a scheduled interest payment date is not a business day (the following unadjusted business day convention), under “Description of Debt Securities—Fixed Rate Debt Securities” in the accompanying prospectus. We describe how interest is calculated, accrued and paid during the Subsequent Fixed Rate Period, including where a scheduled interest payment date is not a business day (the following unadjusted business day convention), under “Description of Debt Securities—Fixed Rate Reset Debt Securities” in this pricing supplement.

Terms not defined herein have the meanings given to such terms in the accompanying prospectus supplement and prospectus, as applicable.

Investing in the notes involves risks. See “Risk Factors” on page PS-5.

The notes are not deposits or savings accounts and are not insured by the Federal Deposit Insurance Corporation or any other governmental agency or instrumentality, nor are they obligations of, or guaranteed by, a bank.

The Securities and Exchange Commission and state securities regulators have not approved or disapproved these securities, or determined if this pricing supplement or the accompanying prospectus supplement or prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

Risk Factors

For a discussion of the risk factors affecting Morgan Stanley and its business, including market risk, credit risk, operational risk, liquidity risk, legal, regulatory and compliance risk, risk management, competitive environment, international risk and acquisition, divestiture and joint venture risk, among others, see “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022 and our current and periodic reports filed pursuant to the Securities Exchange Act of 1934, as amended (file number 001-11758) that are incorporated by reference into this pricing supplement and the accompanying prospectus supplement and prospectus.

This section describes certain selected risk factors relating to the notes. Please see “Risk Factors” in the accompanying prospectus for a complete list of risk factors relating to the notes.

Subordination-Related Risks

Our obligations under the notes will be subordinated. Holders of the notes should recognize that contractual provisions in the Subordinated Indenture, dated as of October 1, 2004, between us and The Bank of New York Mellon (as successor to J.P. Morgan Trust Company, National Association), as trustee (the “Subordinated Debt Indenture”), may prohibit us from making payments on the notes. The notes are subordinate and junior in right of payment, to the extent and in the manner stated in the Subordinated Debt Indenture, to all of our senior indebtedness. The Subordinated Debt Indenture defines senior indebtedness, for purposes of the notes, as obligations of, or guaranteed or assumed by, Morgan Stanley for borrowed money or evidenced by bonds, debentures, notes or other similar instruments, and amendments, renewals, extensions, modifications and refundings of any of that indebtedness or of those obligations. Nonrecourse obligations, the notes and any other obligations specifically designated as being subordinate in right of payment to senior indebtedness are not senior indebtedness as defined under the Subordinated Debt Indenture. In addition, the notes may be fully subordinated to interests held by the U.S. government in the event of receivership, insolvency, liquidation or similar proceedings, including under the “orderly liquidation authority” provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act. For additional information regarding the subordination provisions applicable to the notes, see “Description of Debt Securities—Subordination Provisions” in the accompanying prospectus.

As of September 30, 2023, the notes would have been subordinated to approximately $231.05 billion outstanding carrying amount of senior long-term borrowings. In addition, as a holding company, our assets consist primarily of equity in our subsidiaries and our ability to make payments on the notes depends on our receipt of dividends, distributions and other payments from our subsidiaries. If any of our subsidiaries becomes insolvent, the direct creditors of that subsidiary will have a prior claim on its assets, and our rights and your rights as a holder of the notes will be subject to that prior claim. Moreover, many of our subsidiaries, including our banking and broker-dealer subsidiaries, are subject to laws, regulations and self-regulatory organization rules that authorize regulatory bodies to block or reduce the flow of funds to us, or that prohibit such transfers altogether in certain circumstances, including steps to “ring fence” entities by regulators outside of the U.S. to protect clients and creditors of such entities in the event of financial difficulties involving such entities.

There is no limit on our ability to issue or incur additional senior indebtedness.

In addition, we currently have outstanding subordinated debt securities issued under the Subordinated Debt Indenture with terms and conditions substantially similar to those of the notes. As of September 30, 2023, there was approximately $13.25 billion principal amount of such subordinated long-term borrowings outstanding.

Holders of the notes will have limited rights if there is a default. Payment of principal on the notes may be accelerated only in the event of certain events of bankruptcy, insolvency or reorganization of Morgan Stanley. There is no right of acceleration in the case of default of payment of principal or interest on the notes or in the performance of any of our other obligations under the notes. For additional information regarding defaults, events of default and acceleration under the Subordinated Debt Indenture, see “Description of Debt Securities—Events of Default” in the accompanying prospectus.

Risks Relating to the Notes Generally

The interest rate on the notes will reset once on the Interest Reset Date and the interest rate during the Subsequent Fixed Rate Period could be lower than the interest rate for the Initial Fixed Rate Period. The interest rate on the notes will reset once on the Interest Reset Date and the interest rate for each Interest Payment Period during the Subsequent Fixed Rate Period will equal the Base Rate on the Reset Determination Date plus the Spread. As a result, after the interest rate resets, the interest rate could be lower than the interest rate for the Initial Fixed Rate Period. We have no control over the factors that may affect interest rates, including geopolitical conditions and economic, financial, political, regulatory, judicial or other events that may affect the market generally and interest rates (including the Base Rate) specifically.

PS-5

Risks Relating to the Constant Maturity Treasury Rate

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 Base Rate, (ii) volatility of the level of the Base Rate, (iii) changes in interest and yield rates, (iv) any actual or anticipated changes in our credit ratings or credit spreads and (v) the time remaining to maturity of such notes. 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 Base Rate, 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 issuer, its subsidiaries or affiliates may publish research that could affect the market value of the notes. They also may hedge the issuer’s obligations under such notes. The issuer or one or more of its affiliates may, at present or in the future, publish research reports with respect to movements in interest rates generally, or the Base Rate specifically. This research is modified from time to time without notice 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 such notes. In addition, the issuer’s subsidiaries may hedge the issuer’s obligations under the notes and they may realize a profit from that hedging activity even if investors do not receive a favorable investment return under the terms of such notes or in any secondary market transaction.

The calculation agent (or, if applicable, we or our designee) will make determinations with respect to the notes. The calculation agent will make certain determinations with respect to the notes as further described in this pricing supplement. Any of these determinations may adversely affect the payout to investors. Moreover, certain determinations may require the exercise of discretion and the making of subjective judgments, such as with respect to the Base 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—Fixed Rate Reset Debt Securities” below.

Early Redemption Risks

The notes have early redemption risk. We have the option to redeem the notes, (i) in whole but not in part, on February , 2034, or (ii) in whole at any time or in part from time to time, on or after August , 2038, on at least 5 but not more than 30 days’ prior notice. It is more likely that we will redeem the notes prior to the stated maturity date to the extent that the interest payable on such notes is greater than the interest that would be payable on other instruments of ours of a comparable maturity, of comparable terms and of a comparable credit rating trading in the market. If the notes are redeemed prior to the stated maturity date, you may have to re-invest the proceeds in a lower interest rate environment.

Optional Redemption

We may, at our option, redeem the notes, (i) in whole but not in part, on February , 2034, or (ii) in whole at any time or in part from time to time, on or after August , 2038, on at least 5 but not more than 30 days’ prior notice, at a redemption price equal to 100% of their principal amount, plus accrued and unpaid interest on such notes to but excluding the redemption date. If fewer than all of the notes are to be redeemed, the trustee will select, not more than 30 days prior to the redemption date, the particular notes or portions thereof for redemption from the outstanding notes not previously called for redemption by such method as the trustee deems fair and appropriate; provided, that if the notes are represented by one or more global securities, beneficial interests in such notes will be selected for redemption by the applicable depositary in accordance with its standard procedures therefor.

On or before the respective 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 such notes (unless we default in the payment of the redemption price and accrued interest) and such notes will cease to be outstanding.

Under regulations applicable to us, we may not exercise our option to redeem the notes without obtaining the prior approval of the Federal Reserve (or any successor appropriate federal banking agency). Under such regulations, prior to redeeming the notes, or immediately thereafter, we will be required to either replace the redeemed notes with an equivalent amount of a financial instrument that meets the regulatory capital criteria of the Federal Reserve (or any successor appropriate federal banking agency) or demonstrate to the satisfaction of the Federal Reserve (or any successor appropriate federal banking agency) that following redemption, we would continue to hold an amount of capital that is commensurate with our risk.

For information regarding notices of redemption, see “Description of Debt Securities—Redemption and Repurchase of Debt Securities—Notice of Redemption” in the accompanying prospectus.

PS-6

The notes do not contain any provisions affording the holders the right to require us to purchase the notes after the occurrence of any change in control event affecting us.

Description of Debt Securities—Fixed Rate Reset Debt Securities

The provisions set forth below shall apply to the notes during the Subsequent Fixed Rate Period.

Formula for Interest Rate. The interest rate during the Subsequent Fixed Rate Period will equal:

•

the Base Rate based on the Index Maturity;

•

plus the Spread.

“Index Maturity” means the period of maturity of the instrument or obligation from which the Base Rate is calculated specified above. The “Spread” is the number of basis points (one one-hundredth of a percentage point) specified above to be added to the Base Rate.

Notwithstanding the foregoing, in no event will the interest rate payable for any interest period during the Subsequent Fixed Rate Period be less than zero percent.

Limitations on Interest Rate. The interest rate during the Subsequent Fixed Rate Period may not be higher than the maximum rate permitted by New York law, as that rate may be modified by United States law of general application. Under current New York law, the maximum rate of interest, subject to some exceptions, for any loan in an amount less than $250,000 is 16% and for any loan in the amount of $250,000 or more but less than $2,500,000 is 25% per annum on a simple interest basis. These limits do not apply to loans of $2,500,000 or more.

Determination of Interest Rate. For each interest period during the Subsequent Fixed Rate Period, the notes will bear interest at the interest rate in effect on the Interest Reset Date. The interest rate in effect on the Interest Reset Date will be the rate as reset on that date. The “Reset Determination Date” for the Interest Reset Date will be the second business day prior to the Interest Reset Date.

In the description of the Base Rate under “—Constant Maturity Treasury Rate” below, the “calculation date” pertaining to the Reset Determination Date means the tenth calendar day after the Reset Determination Date, or, if that day is not a business day, the next succeeding business day.

How Interest Is Calculated. Interest during the Subsequent Fixed Rate Period will accrue from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, or, in the case of the first interest period during the Subsequent Fixed Rate Period, from and including the Interest Reset Date. Interest will accrue to but excluding the next Interest Payment Date or, if earlier, the date on which the principal has been paid or duly made available for payment, except as described below under “—If a Payment Date Is Not a Business Day.”

Upon the request of the holder of any notes, the Calculation Agent will provide the interest rate applicable to the notes during the Subsequent Fixed Rate Period after such interest rate has been determined. The Calculation Agent will notify the paying agent of each determination of the interest rate applicable to the notes promptly after the determination is made.

Accrued interest will be calculated by multiplying the principal amount of the notes by an accrued interest factor. This accrued interest factor will be computed by adding the interest factors calculated for each day in the period for which interest is being paid. The interest factor for each day is computed by dividing the interest rate applicable to that day by 360. For these calculations, the interest rate in effect on the Interest Reset Date will be the rate as reset on that date. The interest rate applicable to any other day during the Subsequent Fixed Rate Period is the Interest Rate from the Interest Reset Date.

All percentages used in or resulting from any calculation of the rate of interest during the Subsequent Fixed Rate Period will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with 0.000005% rounded up to 0.00001%, and all U.S. dollar amounts used in or resulting from these calculations will be rounded to the nearest cent, with one-half cent rounded upward.

When Interest Is Paid. We will pay interest on the notes on the Interest Payment Dates specified above.

If a Payment Date Is Not a Business Day. If any scheduled Interest Payment Date is not a business day, we will pay interest on the next business day, but interest on that payment will not accrue during the period from and after the scheduled Interest Payment Date. If the scheduled Maturity Date or date of redemption or repayment is not a business day, we may pay

PS-7

interest, if any, and principal and premium, if any, on the next succeeding business day, but interest on that payment will not accrue during the period from and after the scheduled Maturity Date or date of redemption or repayment.

Constant Maturity Treasury Rate. The Constant Maturity Treasury Rate (the “CMT rate”) means, for the Reset Determination Date, any of the following rates published by the Federal Reserve System Board of Governors, or its successor, on its website or in another recognized electronic source, as the yield is displayed for Treasury securities at “constant maturity” under the column for the Designated CMT Maturity Index, as defined below, for the rate on the Reset Determination Date.

The following procedures will be followed if the CMT rate cannot be determined as described above:

•

If the above rate is no longer displayed on the relevant page, or if not published by 3:00 p.m., New York City time, on the calculation date, then the CMT rate will be the Treasury Constant Maturities rate for the Designated CMT Maturity Index or other U.S. Treasury rate for the Designated CMT Maturity Index on the Reset Determination Date for the Interest Reset Date as may then be published by either the Board of Governors of the Federal Reserve System or the United States Department of the Treasury that the Calculation Agent determines to be comparable to the rate formerly displayed on the Designated CMT Page and published on the website of the Federal Reserve System Board of Governors or in another recognized electronic source.

•

If the information described in the first bullet point is not provided by 3:00 p.m., New York City time, on the calculation date, then the Calculation Agent will determine the CMT rate to be a yield to maturity, based on the arithmetic mean of the secondary market closing offer side prices as of approximately 3:30 p.m., New York City time, on the Reset Determination Date, reported, according to their written records, by three leading primary U.S. government securities dealers, which is referred to as a “reference dealer,” in The City of New York, which may include the agent or another affiliate of ours, selected by us or our designee as described in the following sentence. We or our designee, after consultation with us, will select five reference dealers and will eliminate the highest quotation or, in the event of equality, one of the highest, and the lowest quotation or, in the event of equality, one of the lowest, for the most recently issued direct noncallable fixed rate obligations of the United States, which are commonly referred to as “Treasury notes,” with an original maturity of approximately the Designated CMT Maturity Index, a remaining term to maturity of no more than 1 year shorter than that Designated CMT Maturity Index and in a principal amount that is representative for a single transaction in the securities in that market at that time. If two Treasury notes with an original maturity as described above have remaining terms to maturity equally close to the Designated CMT Maturity Index, the quotes for the Treasury note with the shorter remaining term to maturity will be used.

•

If three Treasury notes quotations are not obtained as described in the immediately preceding bullet, the Calculation Agent will determine the CMT rate to be a yield to maturity based on the arithmetic mean of the secondary market offer side prices as of approximately 3:30 p.m., New York City time, on the Reset Determination Date of three reference dealers in The City of New York, selected using the same method described in the immediately preceding paragraph, for Treasury notes with an original maturity equal to the number of years closest to but not less than the Designated CMT Maturity Index and a remaining term to maturity closest to the Designated CMT Maturity Index and in a principal amount that is representative for a single transaction in the securities in that market at that time.

•

If three or four, and not five, of the reference dealers are quoting as described above, then the CMT rate will be based on the arithmetic mean of the offer prices obtained and neither the highest nor the lowest of those quotes will be eliminated.

•

If fewer than three reference dealers selected by us or our designee are quoting as described above, the rate of interest payable will be the interest rate in effect during the Initial Fixed Rate Period.

“Designated CMT Page” means the display on Bloomberg, or any successor service, on the Reporting Service or any other page as may replace that page on that service for the purpose of displaying Treasury Constant Maturities published by the Federal Reserve System Board of Governors, or its successor, on its website or in another recognized electronic source.

“Designated CMT Maturity Index” means the original period to maturity of the U.S. Treasury securities, which is specified under “Index Maturity” above, for which the CMT rate will be calculated.

United States Federal Taxation

In the opinion of our counsel, Davis Polk & Wardwell LLP, the notes should be treated as “variable rate debt instruments” for U.S. federal tax purposes. Although there is uncertainty regarding their treatment, the notes should be treated as providing for a single fixed rate followed by a single qualified floating rate (“QFR”), as described in the sections of the accompanying prospectus supplement called “United States Federal Taxation―Tax Consequences to U.S. Holders―Notes—Floating Rate Notes―General” and “―Floating Rate Notes that Provide for Multiple Rates.” Under this treatment, in order to determine the

PS-8

amount of qualified stated interest (“QSI”) and original issue discount (“OID”) in respect of the notes, an equivalent fixed rate debt instrument must be constructed for the entire term of the notes. The equivalent fixed rate debt instrument is constructed in the following manner: (i) first, the initial fixed rate is converted to a QFR that would preserve the fair market value of the notes, and (ii) second, each QFR (including the QFR determined under (i) above) is converted to a fixed rate substitute (which should generally be the value of that QFR as of the issue date of the notes). Under Treasury Regulations applicable to certain options arising under the terms of a debt instrument, in determining the amount of QSI and OID, we should be deemed to exercise our optional redemption right if doing so would reduce the yield on the equivalent fixed rate debt instrument. For the purpose of determining QSI and OID, if, as of the issue date, redeeming the notes on the first day of the Subsequent Fixed Rate Period (the “Potential Deemed Redemption Date”) would reduce the yield of the equivalent fixed rate debt instrument, the notes should be treated as fixed rate debt instruments maturing on the Potential Deemed Redemption Date. Under those circumstances, if the notes are not actually redeemed by us on the Potential Deemed Redemption Date, solely for purposes of the OID rules, they should be deemed retired and reissued for their adjusted issue price, and should thereafter be treated as floating rate debt instruments with a term of five years (the “5-year instrument”). The instrument maturing on the Potential Deemed Redemption Date and the 5-year instrument would be treated as issued without OID, and all payments of interest thereon would be treated as QSI.

If, as of the issue date, redeeming the notes on the Potential Deemed Redemption Date would not reduce the yield on the equivalent fixed rate debt instrument, the rules under “United States Federal Taxation―Tax Consequences to U.S. Holders―Notes—Discount Notes―General” should be applied to the equivalent fixed rate debt instrument to determine the amounts of QSI and OID on the notes. Under those circumstances, the notes may be issued with OID.

A U.S. holder is required to include any QSI in income in accordance with the U.S. holder’s regular method of accounting for U.S. federal income tax purposes. U.S. holders will be required to include any OID in income for U.S. federal income tax purposes as it accrues, in accordance with a constant yield method based on a compounding of interest. QSI allocable to an accrual period must be increased (or decreased) by the amount, if any, which the interest actually accrued or paid during an accrual period (including the fixed rate payments made during the initial period) exceeds (or is less than) the interest assumed to be accrued or paid during the accrual period under the equivalent fixed rate debt instrument.

Both U.S. and non-U.S. holders of the notes should read the section of the accompanying prospectus supplement entitled “United States Federal Taxation.”

You should consult your tax adviser regarding all aspects of the U.S. federal tax consequences of an investment in the notes, as well as any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.
