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, 2023 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.

SOFR-Related Risks

The interest rate on the floating rate notes due 2028 and, during the Floating Rate Period, the fixed/floating rate notes due 2028, the fixed/floating rate notes due 2030 and the fixed/floating rate notes due 2035 is based on a daily compounded SOFR rate, which is relatively new in the marketplace. For each Interest Payment Period for the floating rate notes due 2028 and for each Interest Payment Period during the Floating Rate Period for the fixed/floating rate notes due 2028, the fixed/floating rate notes due 2030 and the fixed/floating rate notes due 2035, the interest rate on the notes is based on a daily compounded SOFR rate calculated using the specific formula described in the accompanying prospectus, not the SOFR rate published on or in respect of a particular date during such Interest Payment Period or an average of SOFR rates during such period. For this and other reasons, the interest rate on the notes during any Interest Payment Period for the floating rate notes due 2028 and any Interest Payment Period within the Floating Rate Period for the fixed/floating rate notes due 2028, the fixed/floating rate notes due 2030 and the fixed/floating rate notes due 2035 will not be the same as the interest rate on other SOFR-linked investments that use an alternative basis to determine the applicable interest rate. Further, if the SOFR rate in respect of a particular date during an Interest Payment Period for the floating rate notes due 2028, or during an Interest Payment Period within the Floating Rate Period for the fixed/floating rate notes due 2028, the fixed/floating rate notes due 2030 and the fixed/floating rate notes due 2035 is negative, the portion of the accrued interest compounding factor specifically attributable to such date will be less than one, resulting in a reduction to the accrued interest compounding factor used to calculate the interest payable on such notes on the Interest Payment Date for such Interest Payment Period.

In addition, limited market precedent exists for securities that use SOFR as the interest rate and the method for calculating an interest rate based upon SOFR in those precedents varies. Accordingly, the specific formula for the daily compounded SOFR rate used in the notes may not continue to be utilized by other market participants. If the market transitions to a different calculation method, that would likely adversely affect the market value of such notes.

The amount of interest payable with respect to each Interest Payment Period for the floating rate notes due 2028, and with respect to each Interest Payment Period during the Floating Rate Period for the fixed/floating rate notes due 2028, the fixed/floating rate notes due 2030 and the fixed/floating rate notes due 2035, will be determined near the end of the Interest Payment Period. The level of the Base Rate applicable to each such Interest Payment Period and, therefore, the amount of interest payable with respect to such Interest Payment Period will be determined on the Interest Payment Period End-Date for such Interest Payment Period (or the Rate Cut-Off Date for the final Interest Payment Period). Because each such date is near the end of such Interest Payment Period, you will not know the amount of interest payable with respect to each such Interest Payment Period until shortly prior to the related Interest Payment Date and it may be difficult for you to reliably estimate the amount of interest that will be payable on each such Interest Payment Date.

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 SOFR, (ii) volatility of the level of SOFR, (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 SOFR, 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 LIBOR transition or SOFR 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,

PS-11

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 the accompanying prospectus. In addition, if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, we or our designee will make certain determinations with respect to the notes in our or our designee’s sole discretion as further described under “Description of Debt Securities—SOFR Debt Securities—Determination of SOFR” in the accompanying prospectus. 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 or the occurrence or non-occurrence of a Benchmark Transition Event and any Benchmark Replacement Conforming Changes. 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—SOFR Debt Securities” in the accompanying prospectus.

In determining the Base Rate for the final Interest Payment Period for the floating rate notes due 2028, and for the final Interest Payment Period in the Floating Rate Period for the fixed/floating rate notes due 2028, the fixed/floating rate notes due 2030 and the fixed/floating rate notes due 2035, the level of SOFR for any day from and including the Rate Cut-Off Date to but excluding the Maturity Date or redemption date, as applicable, will be the level of SOFR in respect of such Rate Cut-off Date. For the final Interest Payment Period, because the level of SOFR for any day from and including the Rate Cut-off Date to but excluding the Maturity Date or redemption date, as applicable, will be the level of SOFR in respect of such Rate Cut-Off Date, you will not receive the benefit of any increase in the level in respect of SOFR beyond the level for such date in connection with the determination of the interest payable with respect to such Interest Payment Period, which could adversely impact the amount of interest payable with respect to that Interest Payment Period.

Early Redemption Risks

The notes have early redemption risk. We may redeem the floating rate notes due 2028, (i) in whole but not in part, on April , 2027 or (ii) in whole at any time or in part from time to time, on or after March , 2028, on at least 5 but not more than 30 days’ prior notice. In addition to the optional make-whole redemption discussed above under “Fixed/Floating Rate Notes Due 2028—Other Provisions,” we have the option to redeem the fixed/floating rate notes due 2028, (i) in whole but not in part, on April , 2027 or (ii) in whole at any time or in part from time to time, on or after March , 2028, on at least 5 but not more than 30 days’ prior notice. In addition to the optional make-whole redemption discussed above under “Fixed/Floating Rate Notes Due 2030—Other Provisions,” we have the option to redeem the fixed/floating rate notes due 2030, (i) in whole but not in part, on April , 2029 or (ii) in whole at any time or in part from time to time, on or after March , 2030, on at least 5 but not more than 30 days’ prior notice. In addition to the optional make-whole redemption discussed above under “Fixed/Floating Rate Notes Due 2035—Other Provisions,” we have the option to redeem the fixed/floating rate notes due 2035, (i) in whole but not in part, on April , 2034 or (ii) in whole at any time or in part from time to time, on or after January , 2035, on at least 5 but not more than 30 days’ prior notice. It is more likely that we will redeem the floating rate notes due 2028, the fixed/floating rate notes due 2028, the fixed/floating rate notes due 2030 or the fixed/floating rate notes due 2035 prior to the respective 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 their respective stated maturity dates, you may have to re-invest the proceeds in a lower interest rate environment.

Optional Redemption

We may, at our option, redeem the floating rate notes due 2028, (i) in whole but not in part, on April , 2027 or (ii) in whole at any time or in part from time to time, on or after March , 2028, 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 the floating rate notes due 2028 to but excluding the redemption date. For the avoidance of doubt, if the floating rate notes due 2028 are redeemed in part, the determination of accrued and unpaid interest on the floating rate notes due 2028 so redeemed (determined using a final Interest Payment Date, final Interest Payment Period End-Date and Rate Cut-Off Date relating to the redemption) shall have no effect on the determination of accrued and unpaid interest on the floating rate notes due 2028 that are not so redeemed. Further, if fewer than all of the floating rate notes due 2028 are to be redeemed, the trustee will select, not more than 30 days prior to the redemption date, the particular floating rate notes due 2028 or portions thereof for redemption from the outstanding floating rate notes due 2028 not previously called for redemption by such method as the trustee deems fair and appropriate; provided, that if the floating rate notes due 2028 are represented by one or more global securities, beneficial interests in such floating rate notes due 2028 will be selected for redemption by the applicable depositary in accordance with its standard procedures therefor.

In addition to the optional make-whole redemption discussed above under “Fixed/Floating Rate Notes Due 2028—Other Provisions,” we may, at our option, redeem the fixed/floating rate notes due 2028, (i) in whole but not in part, on April , 2027 or (ii) in whole at any time or in part from time to time, on or after March , 2028, 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 the fixed/floating rate notes due 2028 to but excluding the redemption date. For the avoidance of doubt, if the fixed/floating rate notes due 2028 are redeemed in part, the determination of accrued and unpaid interest on the fixed/floating rate notes due 2028 so redeemed (determined using a final Interest Payment Date, final Interest Payment Period End-Date and Rate Cut-Off Date relating to the redemption) shall have no effect on the determination of accrued and unpaid interest on the fixed/floating rate notes due 2028 that are not so redeemed. Further, if fewer than all of the fixed/floating rate notes due 2028 are to be redeemed, the trustee will select, not more than 30 days prior to the redemption date, the particular fixed/floating rate notes due 2028 or portions thereof for redemption from the outstanding fixed/floating rate notes due 2028 not previously called for redemption by such method as the trustee deems fair and appropriate; provided, that if the fixed/floating rate notes due 2028 are represented by one or more global securities, beneficial interests in such fixed/floating rate notes due 2028 will be selected for redemption by the applicable depositary in accordance with its standard procedures therefor.

In addition to the optional make-whole redemption discussed above under “Fixed/Floating Rate Notes Due 2030—Other Provisions,” we may, at our option, redeem the fixed/floating rate notes due 2030, (i) in whole but not in part, on April , 2029 or (ii) in whole at any time or in part from time to time, on or after March , 2030, 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 fixed/floating rate notes due 2030 to but excluding the redemption date. For the avoidance of doubt, if the fixed/floating rate notes due 2030 are redeemed in part, the determination of accrued and unpaid interest on the fixed/floating rate notes due 2030 so redeemed (determined using a final Interest Payment Date, final Interest Payment Period End-Date and Rate Cut-Off Date relating to the redemption) shall have no effect on the determination of accrued and unpaid interest on the fixed/floating rate notes due 2030 that are not so redeemed. Further, if fewer than all of the fixed/floating rate notes due 2030 are to be redeemed, the trustee will select, not more than 30 days prior to the redemption date, the particular fixed/floating rate notes due 2030 or portions thereof for redemption from the outstanding fixed/floating rate notes due 2030 not previously called for redemption by such method as the trustee deems fair and appropriate; provided, that if the fixed/floating rate notes due 2030 are represented by one or more global securities, beneficial interests in such fixed/floating rate notes due 2030 will be selected for redemption by the applicable depositary in accordance with its standard procedures therefor.

In addition to the optional make-whole redemption discussed above under “Fixed/Floating Rate Notes Due 2035—Other Provisions,” we may, at our option, redeem the fixed/floating rate notes due 2035, (i) in whole but not in part, on April , 2034 or (ii) in whole at any time or in part from time to time, on or after January , 2035, 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 fixed/floating rate notes due 2035 to but excluding the redemption date. For the avoidance of doubt, if the fixed/floating rate notes due 2035 are redeemed in part, the determination of accrued and unpaid interest on the fixed/floating rate notes due 2035 so redeemed (determined using a final Interest Payment Date, final Interest Payment Period End-Date and Rate Cut-Off Date relating to the redemption) shall have no effect on the determination of accrued and unpaid interest on the fixed/floating rate notes due 2035 that are not so redeemed. Further, if fewer than all of the fixed/floating rate notes due 2035 are to be redeemed, the trustee will select, not more than 30 days prior to the redemption date, the particular fixed/floating rate notes due 2035 or portions thereof for redemption from the outstanding fixed/floating rate notes due 2035 not previously called for redemption by such method as the trustee deems fair and appropriate; provided, that if the fixed/floating rate notes due 2035 are represented by one or more global securities, beneficial interests in such fixed/floating rate notes due 2035 will be selected for redemption by the applicable depositary in accordance with its standard procedures therefor.

PS-13

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.

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

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.

Secured Overnight Financing Rate

SOFR is published by the New York Federal Reserve and is intended to be a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities. The New York Federal Reserve reports that SOFR includes all trades in the Broad General Collateral Rate and bilateral Treasury repurchase agreement (repo) transactions cleared through the delivery-versus-payment service offered by the Fixed Income Clearing Corporation (the “FICC”), a subsidiary of The Depository Trust and Clearing Corporation (“DTCC”), and SOFR is filtered by the New York Federal Reserve to remove some (but not all) of the foregoing transactions considered to be “specials.” According to the New York Federal Reserve, “specials” are repos for specific-issue collateral, which take place at cash-lending rates below those for general collateral repos because cash providers are willing to accept a lesser return on their cash in order to obtain a particular security.

The New York Federal Reserve reports that SOFR is calculated as a volume-weighted median of transaction-level tri-party repo data collected from The Bank of New York Mellon as well as General Collateral Finance Repo transaction data and data on bilateral Treasury repo transactions cleared through the FICC’s delivery-versus-payment service. The New York Federal Reserve also notes that it obtains information from DTCC Solutions LLC, an affiliate of DTCC.

If data for a given market segment were unavailable for any day, then the most recently available data for that segment would be utilized, with the rates on each transaction from that day adjusted to account for any change in the level of market rates in that segment over the intervening period. SOFR would be calculated from this adjusted prior day’s data for segments where current data were unavailable, and unadjusted data for any segments where data were available. To determine the change in the level of market rates over the intervening period for the missing market segment, the New York Federal Reserve would use information collected through a daily survey conducted by its Trading Desk of primary dealers’ repo borrowing activity. Such daily survey would include information reported by Morgan Stanley & Co. LLC, a wholly owned subsidiary of Morgan Stanley, as a primary dealer.

The New York Federal Reserve notes on its publication page for SOFR that use of SOFR is subject to important limitations, indemnification obligations and disclaimers, including that the New York Federal Reserve may alter the methods of calculation, publication schedule, rate revision practices or availability of SOFR at any time without notice.

Each U.S. Government Securities Business Day, the New York Federal Reserve publishes SOFR on its website at approximately 8:00 a.m., New York City time. If errors are discovered in the transaction data provided by The Bank of New York Mellon or DTCC Solutions LLC, or in the calculation process, subsequent to the initial publication of SOFR but on that same day, SOFR and the accompanying summary statistics may be republished at approximately 2:30 p.m., New York City time. Additionally, if transaction data from The Bank of New York Mellon or DTCC Solutions LLC had previously not been available in time for publication, but became available later in the day, the affected rate or rates may be republished at around this time. Rate revisions will only be effected on the same day as initial publication and will only be republished if the change in the rate exceeds one basis point. Any time a rate is revised, a footnote to the New York Federal Reserve’s publication would indicate the revision. This revision threshold will be reviewed periodically by the New York Federal Reserve and may be changed based on market conditions.

Because SOFR is published by the New York Federal Reserve based on data received from other sources, we have no control over its determination, calculation or publication. See “Risk Factors” above.

The information contained in this section “Secured Overnight Financing Rate” is based upon the New York Federal Reserve’s Website and other U.S. government sources.

United States Federal Taxation

Tax Considerations for the Floating Rate Notes Due 2028

In the opinion of our counsel, Davis Polk & Wardwell LLP, the floating rate notes due 2028 (the “floating rate-only notes”) should be treated as “variable rate debt instruments” for U.S. federal tax purposes. See the discussion in the section of the accompanying prospectus supplement called “United States Federal Taxation―Tax Consequences to U.S. Holders―Floating Rate Notes―General.”

Tax Considerations for the Fixed/Floating Rate Notes Due 2028, 2030 and 2035

In the opinion of our counsel, Davis Polk & Wardwell LLP, the fixed/floating rate notes due 2028, 2030 and 2035 (for purposes of this discussion, the “notes”) should be treated as “variable rate debt instruments” for U.S. federal tax purposes. Although applicable Treasury Regulations do not directly address the treatment of floating rate debt instruments that provide for redemption rights, such as the notes, each tranche of 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―Floating Rate Notes―General” and “―Floating Rate Notes that Provide for Multiple Rates.” Under this treatment, in order to determine the amount of qualified stated interest (“QSI”) and original issue discount (“OID”) in respect of a tranche of the notes, an equivalent fixed rate debt instrument must be constructed for the entire term of such tranche 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, the optional make-whole redemption should not be deemed to be exercised. However, if, as of the issue date, redeeming a tranche of the notes on the first day of the Floating Rate Interest Period for that tranche of the notes (the “Potential Deemed Redemption Date”) would reduce the yield of the applicable 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 one year (a “1-year instrument”). The instrument maturing on the Potential Deemed Redemption Date would be treated as issued without OID, and all payments of interest thereon would be treated as QSI. Interest on a 1-year instrument should generally be taken into account when received or accrued, according to your method of tax accounting, but it is possible that a 1-year instrument could be subject to the rules described under “United States Federal Taxation―Tax Consequences to U.S. Holders―Short-Term Notes” in the accompanying prospectus supplement.

If, as of the issue date, redeeming a tranche of the notes on the Potential Deemed Redemption Date would not reduce the yield on the applicable equivalent fixed rate debt instrument, the rules under “United States Federal Taxation―Tax Consequences to U.S. Holders― Discount Notes―General” should be applied to the applicable equivalent fixed rate debt instrument to determine the amounts of QSI and OID on the applicable notes. Under those circumstances, the applicable 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 (including the floating rate-only 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 (including the floating rate-only notes), as well as any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

The discussion in the preceding paragraphs under “United States Federal Taxation,” and the discussion contained in the section entitled “United States Federal Taxation” in the accompanying prospectus supplement, insofar as they purport to describe provisions of U.S. federal income tax laws or legal conclusions with respect thereto, constitute the full opinion of Davis Polk & Wardwell LLP regarding the material U.S. federal tax consequences of an investment in the notes (including the floating rate-only notes).
