Call feature:

Beginning on November 19, 2025, 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, as selected by the calculation agent, that is no earlier than three business days before the observation date preceding such redemption date and no later than such observation date (the "determination date"), taking as input: (i) prevailing reference market levels, volatilities and correlations, as applicable and in each case as of the determination date and (ii) Morgan Stanley's credit spreads as of the pricing date, indicates that redeeming on such date is economically rational for us as compared to not redeeming on such date. If we call the securities, we will give you notice no later than the observation date preceding the redemption date specified in the notice. No further payments will be made on the securities once they have been redeemed.

Redemption payment:

The redemption payment will be an amount in cash per stated principal amount (corresponding to a return of at least approximately 15.00% per annum, to be determined on the pricing date) for each monthly redemption date. See "Redemption Dates and Redemption Payments" below.

No further payments will be made on the securities once they have been redeemed.

Redemption dates:

Beginning on November 19, 2025, monthly. See "Redemption Dates and Redemption Payments" below. If any scheduled redemption date is not a business day, the redemption payment will be made on the next succeeding business day and no adjustment will be made to any redemption payment made on that succeeding business day.

Final observation date:

November 13, 2029, subject to postponement due to non-index business days or certain market disruption events. See "Postponement of the final observation date" below.

Payment at maturity:

If the securities have not previously been redeemed, you will receive at maturity a cash payment per security as follows:

●If the final index value is greater than or equal to the initial index value:

$1,000 + ($1,000 × index percent change × 335%)

●If the final index value is less than the initial index value but has not decreased by an amount greater than the buffer amount of 20%:

$1,000 + ($1,000 × absolute index return)

In this scenario, you will receive a 1% positive return on the securities for each 1% negative return on the underlying index. In no event will this amount exceed the stated principal amount plus $200.

●If the final index value has decreased by an amount greater than the buffer amount of 20%:

$1,000 × (index performance factor + 20%)

Under these circumstances, the payment at maturity will be less than the stated principal amount of $1,000. However, under no circumstances will the securities pay less than the minimum payment at maturity of $200 per security.

See "Maturity date" above.

See "Payment at maturity" above.

Maturity:

Approximately 5 years

Payment at maturity:

If the securities have not previously been redeemed, you will receive at maturity a cash payment per security as follows:

●If the final index value is greater than or equal to the initial index value:

$1,000 + ($1,000 × index percent change × 335%)

●If the final index value is less than the initial index value but has not decreased by an amount greater than the buffer amount of 20% from the initial index value:

$1,000 + ($1,000 × absolute index return)

In this scenario, you will receive a 1% positive return on the securities for each 1% negative return on the underlying index. In no event will this amount exceed the stated principal amount plus $200.

●If the final index value has decreased by an amount greater than the buffer amount of 20% from the initial index value:

$1,000 × (index performance factor + 20%)

Under these circumstances, the payment at maturity will be less than the stated principal amount of $1,000. However, under no circumstances will the securities pay less than the minimum payment at maturity of $200 per security.

Early redemption:

Beginning on November 19, 2025, we will redeem the securities on any monthly redemption date for a redemption payment equal to a redemption payment that will increase over the term of the securities and that will correspond to a return of at least approximately 15.00% per annum (to be determined on the pricing date) with respect to the related redemption date, if and only if the output of a risk neutral valuation model on a business day, as selected by the calculation agent, that is no earlier than three business days before the observation date preceding such redemption date and no later than such observation date, based on the inputs indicated under "Call feature", indicates that redeeming on such date is economically rational for us as compared to not redeeming on such date. An early redemption of the securities will not automatically occur based on the performance of the underlying index. In accordance with the risk neutral valuation model determination noted herein, it is more likely that we will redeem the securities when it would otherwise be advantageous for you to continue to hold the securities. As such, we will be more likely to redeem the securities when the index closing value of the underlying index on the redemption dates is above the initial index value. If the securities are redeemed prior to maturity, you will not participate in any appreciation of the underlying index, which could be significant. Moreover, the fixed redemption payments may be less than the payment at maturity you would receive for the same level of appreciation of the underlying index had the securities not been redeemed and instead remained outstanding until maturity.

On the other hand, we will be less likely to redeem the securities when the index closing value of the underlying index is less than the initial index value by an amount greater than the specified buffer amount, such that you will suffer a significant loss on your initial investment in the securities at maturity. Therefore, if we do not redeem the securities, it is more likely that you will suffer a significant loss at maturity.

Redemption payments:

The redemption payment will be an amount in cash per stated principal amount (corresponding to a return of at least 15.00% per annum (to be determined on the pricing date) for each monthly redemption date, as follows*:

Scenario 1: The securities are redeemed prior to maturity

This scenario assumes that we redeem the securities based on the output of a risk neutral valuation model prior to the maturity date on one of the monthly redemption dates, starting on November 19, 2025, for the redemption payment equal to a return of at least approximately 15.00% per annum (to be determined on the pricing date) with respect to the relevant redemption date, as applicable. No further payments will be made on the securities once they have been redeemed.

Scenario 2: The securities are not redeemed prior to maturity, and the underlying index appreciates

This scenario assumes that we do not redeem the securities on any of the monthly redemption dates, and, as a result, investors hold the securities to maturity. On the final observation date, the underlying index closes above the initial index value. At maturity, investors will receive the stated principal amount of their investment plus a return reflecting 335% of the upside performance of the underlying index.

Scenario 3: The securities are not redeemed prior to maturity, and the final index value of the underlying index is less than the initial index value but greater or equal to than the specified buffer amount

This scenario assumes that we do not redeem the securities on any of the monthly redemption dates, and, as a result, investors hold the securities to maturity. On the final observation date, the underlying index closes below the initial index value, but has not decreased by an amount greater than the specified buffer amount of 20%. At maturity, investors will receive a 1% positive return on the securities for each 1% negative return on the underlying index. For example, if the final index value of the underlying index is 10% less than the initial index value, the securities will provide a total positive return of 10% at maturity. The maximum return investors may receive in this scenario is a positive 20% return at maturity.

Scenario 4: The securities are not redeemed prior to maturity, and investors suffer a loss of principal at maturity

This scenario assumes that we do not redeem the securities on any of the monthly redemption dates, and, as a result, investors hold the securities to maturity. On the final observation date, the underlying index closes below the initial index value by an amount greater than the buffer amount of 20%. At maturity, investors will receive an amount that is less than the stated principal amount by an amount that is proportionate to the percentage decrease of the underlying index from the initial index value beyond the buffer amount. Under these circumstances, the payment at maturity will be less than the stated principal amount. Investors may lose up to 80% of their investment in the securities.

Call Feature:

Beginning on November 19 2025, 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, as selected by the calculation agent, that is no earlier than three business days before the observation date preceding such redemption date and no later than such observation date (the "determination date"), taking as input: (i) prevailing reference market levels, volatilities and correlations, as applicable and in each case as of the determination date and (ii) Morgan Stanley's credit spreads as of the pricing date, indicates that redeeming on such date is economically rational for us as compared to not redeeming on such date. If we call the securities, we will give you notice no later than the observation date preceding the redemption date specified in the notice.

Hypothetical Redemption Payment:

The hypothetical redemption payment will be an amount in cash per stated principal amount (corresponding to a return of approximately 15.00% per annum) for each monthly redemption date, as follows:

Payment at Maturity

If the securities have not previously been redeemed, you will receive at maturity a cash payment per security as follows:

●If the final index value is greater than or equal to the initial index value:

$1,000 + ($1,000 × index percent change × 335%)

●If the final index value is less than the initial index value but has not decreased by an amount greater than the buffer amount of 20%:

$1,000 + ($1,000 × absolute index return)

In this scenario, you will receive a 1% positive return on the securities for each 1% negative return on the underlying index. In no event will this amount exceed the stated principal amount plus $200.

●If the final index value has decreased by an amount greater than the buffer amount of 20%:

$1,000 × (index performance factor + 20%).

Under these circumstances, the payment at maturity will be less than the stated principal amount of $1,000. However, under no circumstances will the securities pay less than the minimum payment at maturity of $200 per security.

Calculation agent:

The calculation agent for the securities will be MS & Co. All determinations made by the calculation agent will be at the sole discretion of the calculation agent and will, in the absence of manifest error, be conclusive for all purposes and binding on you, the trustee and us.

All calculations with respect to the redemption payments and the payment at maturity, shall be made by the calculation agent and shall be rounded to the nearest one hundred-thousandth, with five one-millionths rounded upward (e.g., .876545 would be rounded to .87655); all dollar amounts related to determination of the amount of cash payable per stated principal amount, if any, shall be rounded to the nearest ten-thousandth, with five one hundred-thousandths rounded upward (e.g., .76545 would be rounded up to .7655); and all dollar amounts paid on the aggregate principal amount of the securities shall be rounded to the nearest cent, with one-half cent rounded upward.

Because the calculation agent is our affiliate, the economic interests of the calculation agent and its affiliates may be adverse to your interests as an investor in the securities, including with respect to certain determinations and judgments that the calculation agent must make in determining the payment that you will receive, upon early redemption or at maturity or whether a market disruption event has occurred. See "Market disruption event" and "Discontinuance of an underlying index; alteration of method of calculation" below. MS & Co. is obligated to carry out its duties and functions as calculation agent in good faith and using its reasonable judgment.

Business day:

Any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions are authorized or required by law or regulation to close in The City of New York.

Index business day:

With respect to the underlying index, a day, as determined by the calculation agent, on which trading is generally conducted on each of the relevant exchange(s) for the underlying index, other than a day on which trading on such exchange(s) is scheduled to close prior to the time of the posting of its regular final weekday closing price.

Market disruption event:

With respect to the underlying index, market disruption event means:

(i)the occurrence or existence of any of:

(a) a suspension, absence or material limitation of trading of securities then constituting 20 percent or more of the value of the underlying index (or a successor index) on the relevant exchange(s) for such securities for more than two hours of trading or during the one-half hour period preceding the close of the principal trading session on such relevant exchange(s), or

(b) a breakdown or failure in the price and trade reporting systems of any relevant exchange as a result of which the reported trading prices for securities then constituting 20 percent or more of the value of the underlying index (or a successor index) during the last one-half hour preceding the close of the principal trading session on such relevant exchange(s) are materially inaccurate, or

(c) the suspension, material limitation or absence of trading on any major U.S. securities market for trading in futures or options contracts or exchange-traded funds related to the underlying index (or a successor index) for more than two hours of trading or during the one-half hour period preceding the close of the principal trading session on such

market,

in each case as determined by the calculation agent in its sole discretion; and

(ii)a determination by the calculation agent in its sole discretion that any event described in clause (i) above materially interfered with our ability or the ability of any of our affiliates to unwind or adjust all or a material portion of the hedge position with respect to the securities.

For the purpose of determining whether a market disruption event exists at any time with respect to the underlying index, if trading in a security included in the underlying index is materially suspended or materially limited at that time, then the relevant percentage contribution of that security to the value of such underlying index shall be based on a comparison of (x) the portion of the value of the underlying index attributable to that security relative to (y) the overall value of the underlying index, in each case immediately before that suspension or limitation.

For the purpose of determining whether a market disruption event exists at any time with respect to the underlying index: (1) a limitation on the hours or number of days of trading will not constitute a market disruption event if it results from an announced change in the regular business hours of the relevant exchange or market, (2) a decision to permanently discontinue trading in the relevant futures or options contract or exchange-traded fund will not constitute a market disruption event, (3) a suspension of trading in futures or options contracts or exchange-traded funds on the underlying index by the primary securities market trading in such contracts or funds by reason of (a) a price change exceeding limits set by such securities exchange or market, (b) an imbalance of orders relating to such contracts or funds or (c) a disparity in bid and ask quotes relating to such contracts or funds will constitute a suspension, absence or material limitation of trading in futures or options contracts or exchange-traded funds related to the underlying index and (4) a "suspension, absence or material limitation of trading" on any relevant exchange or on the primary market on which futures or options contracts or exchange-traded funds related to the underlying index are traded will not include any time when such securities market is itself closed for trading under ordinary circumstances.

Relevant exchange:

With respect to the underlying index or its successor index, the primary exchange(s) or market(s) of trading for (i) any security then included in such index and (ii) any futures or options contracts related to the index or to any security then included in the index.

Postponement of the final observation date:

The final observation date is subject to postponement due to non-index business days or certain market disruption events, as described in the following paragraph.

If the final observation date is not an index business day with respect to the underlying index or if there is a market disruption event on such day with respect to the underlying index, the final observation date shall be the next succeeding index business day with respect to the underlying index on which there is no market disruption event with respect to the underlying index; provided that if a market disruption event with respect to the underlying index has occurred on each of the five index business days with respect to the underlying index immediately succeeding the scheduled final observation date, then (i) such fifth succeeding index business day shall be deemed to be the final observation date with respect to the underlying index, notwithstanding the occurrence of a market disruption event with respect to the underlying index on such day and (ii) with respect to any such fifth index business day on which a market disruption event occurs with respect to the underlying index, the calculation agent shall determine the index closing value on such fifth index business day in accordance with the formula for and method of calculating the underlying index last in effect prior to the commencement of the market disruption event, using the closing price (or, if trading in the relevant securities has been materially suspended or materially limited, its good faith estimate of the closing price that would have prevailed but for such suspension or limitation) at the close of the principal trading session of the relevant exchange on such index business day of each security most recently constituting the underlying index without any rebalancing or substitution of such securities following the commencement of the market disruption event.

Postponement of the maturity date and redemption dates:

If any applicable redemption date or the maturity date is not a business day, that redemption payment, if applicable, or payment at maturity shall be paid on the next succeeding business day; provided that if, due to a market disruption event or otherwise, any observation date with respect to the underlying index is postponed so that it falls less than two business days prior to the scheduled maturity date, the maturity date or redemption date, as applicable, shall be postponed to the second business day following the final observation date as postponed, by which date the index closing value of the underlying index has been determined. In any of these cases, no adjustment shall be made to any payment at maturity or redemption payment made on a postponed date.

Discontinuance of the underlying index; alteration of method of calculation:

If the underlying index publisher discontinues publication of the underlying index and the underlying index publisher or another entity (including MS & Co.) publishes a successor or substitute index that the calculation agent determines, in its sole discretion, to be comparable to the discontinued index (such index being referred to herein as the "successor index"), then any subsequent index closing value for the discontinued index will be determined by reference to the published value of such successor index at the regular weekday close of trading on any index business day that the index closing value for the underlying index is to be determined, and, to the extent the index closing value of such successor index differs from the index closing value of the underlying index at the time of such substitution, proportionate adjustments shall be made by the calculation agent to the initial index value and buffer amount.

Upon any selection by the calculation agent of a successor index, the calculation agent will cause written notice thereof to be furnished to the trustee, to us and to the depositary, as holder of the securities, within three business days of such selection. We expect that such notice will be made available to you, as a beneficial owner of the securities, in accordance with the standard rules and procedures of the depositary and its direct and indirect participants.

If the underlying index publisher discontinues publication of the underlying index or a successor index prior to, and such discontinuance is continuing on, the final observation date and the calculation agent determines, in its sole discretion, that no successor index is available at such time, then the calculation agent will determine the index closing value for the underlying index for such date. The index closing value of the underlying index or such successor index will be computed by the calculation agent in accordance with the formula for and method of calculating such index last in effect prior to such discontinuance, using the closing price (or, if trading in the relevant securities has been materially suspended or materially limited, its good faith estimate of the closing price that would have prevailed but for such suspension or limitation) at the close of the principal trading session of the relevant exchange on such date of each security most recently constituting such index without any rebalancing or substitution of such securities following such discontinuance. Notwithstanding these alternative arrangements, discontinuance of the publication of the underlying index may adversely affect the value of the securities.

If at any time, the method of calculating the underlying index or any successor index, or the value thereof, is changed in a material respect, or if the underlying index or any successor index is in any other way modified so that such index does not, in the opinion of the calculation agent, fairly represent the value of such index had such changes or modifications not been made, then, from and after such time, the calculation agent will, at the close of business in New York City on each date on which the index closing value for the underlying index is to be determined, make such calculations and adjustments as, in the good faith judgment of the calculation agent, may be necessary in order to arrive at a value of a stock index comparable to the underlying index or such successor index, as the case may be, as if such changes or modifications had not been made, and the calculation agent will calculate the index closing value with reference to the underlying index or such successor index, as adjusted. Accordingly, if the method of calculating the underlying index or any successor index is modified so that the value of such index is a fraction of what it would have been if it had not been modified (e.g., due to a split in the underlying index), then the calculation agent will adjust such index in order to arrive at a value of the underlying index or such successor index as if it had not been modified (e.g., as if such split had not occurred).

Issuer notices to registered security holders, the trustee and the depositary:

In the event that the maturity date is postponed due to postponement of the final observation date, the issuer shall give notice of such postponement and, once it has been determined, of the date to which the maturity date has been rescheduled (i) to each registered holder of the securities by mailing notice of such postponement by first class mail, postage prepaid, to such registered holder's last address as it shall appear upon the registry books, (ii) to the trustee by facsimile, confirmed by mailing such notice to the trustee by first class mail, postage prepaid, at its New York office and (iii) to The Depository Trust Company (the "depositary") by telephone or facsimile confirmed by mailing such notice to the depositary by first class mail, postage prepaid. Any notice that is mailed to a registered holder of the securities in the manner herein provided shall be conclusively presumed to have been duly given to such registered holder, whether or not such registered holder receives the notice. The issuer shall give such notice as promptly as possible, and in no case later than (i) with respect to notice of postponement of the maturity date, the business day immediately preceding the scheduled maturity date, and (ii) with respect to notice of the date to which the maturity date has been rescheduled, the business day immediately following the final observation date as postponed.

In the event that the securities are subject to early redemption, the issuer shall, (i) on the business day following the applicable redemption date, give notice of the early redemption and the redemption payment, including specifying the payment date of the amount due upon the early

redemption, (x) to each registered holder of the securities by mailing notice of such early redemption by first class mail, postage prepaid, to such registered holder's last address as it shall appear upon the registry books, (y) to the trustee by facsimile confirmed by mailing such notice to the trustee by first class mail, postage prepaid, at its New York office and (z) to the depositary by telephone or facsimile confirmed by mailing such notice to the depositary by first class mail, postage prepaid and (ii) on or prior to the early redemption date, deliver the aggregate cash amount due with respect to the securities to the trustee for delivery to the depositary, as holder of the securities. Any notice that is mailed to a registered holder of the securities in the manner herein provided shall be conclusively presumed to have been duly given to such registered holder, whether or not such registered holder receives the notice. This notice shall be given by the issuer or, at the issuer's request, by the trustee in the name and at the expense of the issuer, with any such request to be accompanied by a copy of the notice to be given.

The issuer shall, or shall cause the calculation agent to, (i) provide written notice to the trustee, on which notice the trustee may conclusively rely, and to the depositary of the amount of cash, if any, to be delivered with respect to each security on or prior to 10:30 a.m. (New York City time) on the business day preceding the maturity date, and (ii) deliver the aggregate cash amount due with respect to the securities, if any, to the trustee for delivery to the depositary, as holder of the securities, on the maturity date.

Alternate exchange calculation in case of an event of default:

If an event of default with respect to the securities shall have occurred and be continuing, the amount declared due and payable upon any acceleration of the securities (the "Acceleration Amount") will be an amount, determined by the calculation agent in its sole discretion, that is equal to the cost of having a qualified financial institution, of the kind and selected as described below, expressly assume all our payment and other obligations with respect to the securities as of that day and as if no default or acceleration had occurred, or to undertake other obligations providing substantially equivalent economic value to you with respect to the securities. That cost will equal:

●the lowest amount that a qualified financial institution would charge to effect this assumption or undertaking, plus

●the reasonable expenses, including reasonable attorneys' fees, incurred by the holders of the securities in preparing any documentation necessary for this assumption or undertaking.

During the default quotation period for the securities, which we describe below, the holders of the securities and/or we may request a qualified financial institution to provide a quotation of the amount it would charge to effect this assumption or undertaking. If either party obtains a quotation, it must notify the other party in writing of the quotation. The amount referred to in the first bullet point above will equal the lowest-or, if there is only one, the only-quotation obtained, and as to which notice is so given, during the default quotation period. With respect to any quotation, however, the party not obtaining the quotation may object, on reasonable and significant grounds, to the assumption or undertaking by the qualified financial institution providing the quotation and notify the other party in writing of those grounds within two business days after the last day of the default quotation period, in which case that quotation will be disregarded in determining the Acceleration Amount.

Notwithstanding the foregoing, if a voluntary or involuntary liquidation, bankruptcy or insolvency of, or any analogous proceeding is filed with respect to MSFL or Morgan Stanley, then depending on applicable bankruptcy law, your claim may be limited to an amount that could be less than the Acceleration Amount.

If the maturity of the securities is accelerated because of an event of default as described above, we shall, or shall cause the calculation agent to, provide written notice to the trustee at its New York office, on which notice the trustee may conclusively rely, and to the depositary of the Acceleration Amount and the aggregate cash amount due, if any, with respect to the securities as promptly as possible and in no event later than two business days after the date of such acceleration.

Default quotation period

The default quotation period is the period beginning on the day the Acceleration Amount first becomes due and ending on the third business day after that day, unless:

●no quotation of the kind referred to above is obtained, or

●every quotation of that kind obtained is objected to within five business days after the due date as described above.

If either of these two events occurs, the default quotation period will continue until the third business day after the first business day on which prompt notice of a quotation is given as described above. If that quotation is objected to as described above within five business days

after that first business day, however, the default quotation period will continue as described in the prior sentence and this sentence.

In any event, if the default quotation period and the subsequent two business day objection period have not ended before the final observation date, then the Acceleration Amount will equal the principal amount of the securities.

Qualified financial institutions

For the purpose of determining the Acceleration Amount at any time, a qualified financial institution must be a financial institution organized under the laws of any jurisdiction in the United States or Europe, which at that time has outstanding debt obligations with a stated maturity of one year or less from the date of issue and rated either:

●A-2 or higher by Standard & Poor's Ratings Services or any successor, or any other comparable rating then used by that rating agency, or

P-2 or higher by Moody's Investors Service or any successor, or any other comparable rating then used by that rating agency.

$1,000 / 1 security

Book entry security or certificated security:

Book entry. The securities will be issued in the form of one or more fully registered global securities which will be deposited with, or on behalf of, The Depository Trust Company (the "depositary") and will be registered in the name of a nominee of the depositary. The depositary's nominee will be the only registered holder of the securities. Your beneficial interest in the securities will be evidenced solely by entries on the books of the securities intermediary acting on your behalf as a direct or indirect participant in the depositary. In this preliminary pricing supplement, all references to payments or notices to you will mean payments or notices to the depositary, as the registered holder of the securities, for distribution to participants in accordance with the depositary's procedures. For more information regarding the depositary and book entry notes, please read "Forms of Securities-The Depositary" and "Forms of Securities-Global Securities" in the accompanying prospectus.

Tax considerations:

Prospective investors should note that the discussion under the section called "United States Federal Taxation" in the accompanying prospectus supplement does not apply to the securities issued under this preliminary pricing supplement and is superseded by the following discussion.

The following summary is a general discussion of the principal U.S. federal income tax consequences and certain estate tax consequences of the ownership and disposition of the securities. This discussion applies only to investors in the securities who:

●purchase the securities in the original offering; and

●hold the securities as capital assets within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the "Code").

This discussion does not describe all of the tax consequences that may be relevant to a holder in light of the holder's particular circumstances or to holders subject to special rules, such as:

●certain financial institutions;

●insurance companies;

●dealers and certain traders in securities or commodities;

●investors holding the securities as part of a "straddle," wash sale, conversion transaction, integrated transaction or constructive sale transaction;

●U.S. Holders (as defined below) whose functional currency is not the U.S. dollar;

●partnerships or other entities classified as partnerships for U.S. federal income tax purposes;

●regulated investment companies;

●real estate investment trusts; or

●tax-exempt entities, including "individual retirement accounts" or "Roth IRAs" as defined in Section 408 or 408A of the Code, respectively.

If an entity that is classified as a partnership for U.S. federal income tax purposes holds the securities, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. If you are a partnership holding the securities or a partner in such a partnership, you should consult your tax adviser as to the particular U.S. federal tax consequences of holding and disposing of the securities to you.

In addition, we will not attempt to ascertain whether any issuer of any shares to which a security relates (such shares hereafter referred to as "Underlying Shares") is treated as a "passive foreign investment company" ("PFIC") within the meaning of Section 1297 of the Code or as a "U.S. real property holding corporation" ("USRPHC") within the meaning of Section 897 of the Code. If any issuer of Underlying Shares were so treated, certain adverse U.S. federal income tax consequences might apply, to a U.S. Holder in the case of a PFIC and to a Non-U.S. Holder (as

defined below) in the case of a USRPHC, upon the sale, exchange or settlement of the securities. You should refer to information filed with the Securities and Exchange Commission or other governmental authorities by the issuers of the Underlying Shares and consult your tax adviser regarding the possible consequences to you if any issuer is or becomes a PFIC or USRPHC.

As the law applicable to the U.S. federal income taxation of instruments such as the securities is technical and complex, the discussion below necessarily represents only a general summary. Moreover, the effect of any applicable state, local or non-U.S. tax laws is not discussed, nor are any alternative minimum tax consequences or consequences resulting from the Medicare tax on investment income.

This discussion is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations, all as of the date of this preliminary pricing supplement, changes to any of which subsequent to the date hereof may affect the tax consequences described herein. Persons considering the purchase of the securities should consult their tax advisers with regard to the application of the U.S. federal income tax laws to their particular situations as well as any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

General

Although there is uncertainty regarding the U.S. federal income tax consequences of an investment in the securities due to the lack of governing authority, in the opinion of our counsel, under current law, and based on current market conditions, each security should be treated as a single financial contract that is an "open transaction" for U.S. federal income tax purposes. However, because our counsel's opinion is based in part on market conditions as of the date of this preliminary pricing supplement, it is subject to confirmation on the pricing date.

Due to the absence of statutory, judicial or administrative authorities that directly address the treatment of the securities or instruments that are similar to the securities for U.S. federal income tax purposes, no assurance can be given that the Internal Revenue Service (the "IRS") or a court will agree with the tax treatment described herein. Accordingly, you should consult your tax adviser regarding all aspects of the U.S. federal tax consequences of an investment in the securities (including possible alternative treatments of the securities). Unless otherwise stated, the following discussion is based on the treatment of the securities as described in the previous paragraph.

Tax Consequences to U.S. Holders

This section applies to you only if you are a U.S. Holder. As used herein, the term "U.S. Holder" means a beneficial owner of a security that is, for U.S. federal income tax purposes:

●a citizen or individual resident of the United States;

●a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States, any state thereof or the District of Columbia; or

●an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.

Tax Treatment of the Securities

Assuming the treatment of the securities as set forth above is respected, the following U.S. federal income tax consequences should result.

Tax Treatment Prior to Settlement. A U.S. Holder should not be required to recognize taxable income over the term of the securities prior to settlement, other than pursuant to a sale or exchange as described below.

Tax Basis. A U.S. Holder's tax basis in the securities should equal the amount paid by the U.S. Holder to acquire the securities.

Sale, Exchange or Settlement of the Securities. Upon a sale, exchange or settlement of the securities, a U.S. Holder should recognize gain or loss equal to the difference between the amount realized on the sale, exchange or settlement and the U.S. Holder's tax basis in the

securities sold, exchanged or settled. Subject to the discussion above regarding the possible application of Section 1297 of the Code, any gain or loss recognized upon the sale, exchange or settlement of the securities should be long-term capital gain or loss if the U.S. Holder has held the securities for more than one year at such time, and short-term capital gain or loss otherwise.

Possible Alternative Tax Treatments of an Investment in the Securities

Due to the absence of authorities that directly address the proper tax treatment of the securities, no assurance can be given that the IRS will accept, or that a court will uphold, the treatment described above. In particular, the IRS could seek to analyze the U.S. federal income tax consequences of owning the securities under Treasury regulations governing contingent payment debt instruments (the "Contingent Debt Regulations"). If the IRS were successful in asserting that the Contingent Debt Regulations applied to the securities, the timing and character of income thereon would be significantly affected. Among other things, a U.S. Holder would be required to accrue into income original issue discount on the securities every year at a "comparable yield" determined at the time of their issuance, adjusted upward or downward to reflect the difference, if any, between the actual and the projected amount of the contingent payment on the securities. Furthermore, any gain realized by a U.S. Holder at maturity or upon a sale, exchange or other disposition of the securities would generally be treated as ordinary income, and any loss realized would be treated as ordinary loss to the extent of the U.S. Holder's prior accruals of original issue discount and as capital loss thereafter. The risk that financial instruments providing for buffers, triggers or similar downside protection features, such as the securities, would be recharacterized as debt is greater than the risk of recharacterization for comparable financial instruments that do not have such features.

Other alternative federal income tax treatments of the securities are also possible, which, if applied, could significantly affect the timing and character of the income or loss with respect to the securities. In 2007, the U.S. Treasury Department and the IRS released a notice requesting comments on the U.S. federal income tax treatment of "prepaid forward contracts" and similar instruments. The notice focuses in particular on whether to require holders of these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments; whether short-term instruments should be subject to any such accrual regime; the relevance of factors such as the exchange-traded status of the instruments and the nature of the underlying property to which the instruments are linked; and whether these instruments are or should be subject to the "constructive ownership" rule, which very generally can operate to recharacterize certain long-term capital gain as ordinary income and impose an interest charge. While the notice requests comments on appropriate transition rules and effective dates, any 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. U.S. Holders should consult their tax advisers regarding the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments and the issues presented by this notice.

Backup Withholding and Information Reporting

Backup withholding may apply in respect of the payment on the securities at maturity and the payment of proceeds from a sale, exchange or other disposition of the securities, unless a U.S. Holder provides proof of an applicable exemption or a correct taxpayer identification number and otherwise complies with applicable requirements of the backup withholding rules. The amounts withheld under the backup withholding rules are not an additional tax and may be refunded, or credited against the U.S. Holder's U.S. federal income tax liability, provided that the required information is timely furnished to the IRS. In addition, information returns may be filed with the IRS in connection with the payment on the securities and the payment of proceeds from a sale, exchange or other disposition of the securities, unless the U.S. Holder provides proof of an applicable exemption from the information reporting rules.

Tax Consequences to Non-U.S. Holders

This section applies to you only if you are a Non-U.S. Holder. As used herein, the term "Non-U.S. Holder" means a beneficial owner of a security that is, for U.S. federal income tax purposes:

●an individual who is classified as a nonresident alien;

●a foreign corporation; or

●a foreign estate or trust.

The term "Non-U.S. Holder" does not include any of the following holders:

●a holder who is an individual present in the United States for 183 days or more in the taxable year of disposition and who is not otherwise a resident of the United States for U.S. federal income tax purposes;

●certain former citizens or residents of the United States; or

●a holder for whom income or gain in respect of the securities is effectively connected with the conduct of a trade or business in the United States.

Such holders should consult their tax advisers regarding the U.S. federal income tax consequences of an investment in the securities.

Tax Treatment upon Sale, Exchange or Settlement of the Securities

In general. Assuming the treatment of the securities as set forth above is respected, and subject to the discussions below concerning backup withholding and the possible application of Section 871(m) of the Code and the discussion above concerning the possible application of Section 897 of the Code, a Non-U.S. Holder of the securities generally will not be subject to U.S. federal income or withholding tax in respect of amounts paid to the Non-U.S. Holder.

Subject to the discussions regarding the possible application of Sections 871(m) and 897 of the Code and FATCA, if all or any portion of a security were recharacterized as a debt instrument, any payment made to a Non-U.S. Holder with respect to the securities would not be subject to U.S. federal withholding tax, provided that:

●the Non-U.S. Holder does not own, directly or by attribution, ten percent or more of the total combined voting power of all classes of Morgan Stanley stock entitled to vote;

●the Non-U.S. Holder is not a controlled foreign corporation related, directly or indirectly, to Morgan Stanley through stock ownership;

●the Non-U.S. Holder is not a bank receiving interest under Section 881(c)(3)(A) of the Code, and

●the certification requirement described below has been fulfilled with respect to the beneficial owner.

Certification Requirement. The certification requirement referred to in the preceding paragraph will be fulfilled if the beneficial owner of a security (or a financial institution holding a security on behalf of the beneficial owner) furnishes to the applicable withholding agent an IRS Form W-8BEN (or other appropriate form) on which the beneficial owner certifies under penalties of perjury that it is not a U.S. person.

In 2007, the U.S. Treasury Department and the IRS released a notice requesting comments on the U.S. federal income tax treatment of "prepaid forward contracts" and similar instruments. Among the issues addressed in the notice is the degree, if any, to which any income with respect to instruments such as the securities should be subject to U.S. withholding tax. It is possible that any Treasury regulations or other guidance promulgated after consideration of this issue could materially and adversely affect the withholding tax consequences of ownership and disposition of the securities, possibly on a retroactive basis. Non-U.S. Holders should note that we currently do not intend to withhold on any payment made with respect to the securities to Non-U.S. Holders (subject to compliance by such holders with the certification requirement described above and to the discussions regarding Sections 871(m) and 897 of the Code and FATCA). However, in the event of a change of law or any formal or informal guidance by the IRS, the U.S. Treasury Department or Congress, we may decide to withhold on payments made with respect to the securities to Non-U.S. Holders, and we will not be required to pay any additional amounts with respect to amounts withheld. Accordingly, Non-U.S. Holders should consult their tax advisers regarding all aspects of the U.S. federal income tax consequences of an investment in the securities, including the possible implications of the notice referred to above.

Section 871(m) Withholding Tax on Dividend Equivalents

Section 871(m) of the Code and Treasury regulations promulgated thereunder ("Section 871(m)") generally impose a 30% (or a lower applicable treaty rate) 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 (each, an "Underlying Security"). Subject to certain exceptions, Section 871(m) generally applies to securities that substantially replicate the economic performance of one or more Underlying Securities, as determined based on tests set forth in the applicable Treasury regulations (a "Specified Security"). However, pursuant to an IRS notice, Section 871(m) will not apply to securities issued before January 1, 2027 that do not have a delta of one with respect to any Underlying Security. Based on the terms of the securities and current market conditions, we expect that the securities will not have a delta of one with respect to any Underlying Security on the pricing date. However, we will provide an updated determination in the final pricing supplement. Assuming that the securities do not have a delta of one with respect to any Underlying Security, our counsel is of the opinion that the securities should not be Specified Securities and, therefore, should not be subject to Section 871(m).

Our determination is not binding on the IRS, and the IRS may disagree with this determination. Section 871(m) is complex and its application may depend on your particular circumstances, including whether you enter into other transactions with respect to an Underlying Security. If withholding is required, we will not be required to pay any additional amounts with respect to the amounts so withheld. You should consult your tax adviser regarding the potential application of Section 871(m) to the securities.

U.S. Federal Estate Tax

Individual Non-U.S. Holders and entities the property of which is potentially includible in such an individual's gross estate for U.S. federal estate tax purposes (for example, a trust funded by such an individual and with respect to which the individual has retained certain interests or powers), should note that, absent an applicable treaty exemption, the securities may be treated as U.S. situs property subject to U.S. federal estate tax. Prospective investors that are non-U.S. individuals, or are entities of the type described above, should consult their tax advisers regarding the U.S. federal estate tax consequences of an investment in the securities.

Backup Withholding and Information Reporting

Information returns may be filed with the IRS in connection with the payment on the securities at maturity as well as in connection with the payment of proceeds from a sale, exchange or other disposition of the securities. A Non-U.S. Holder may be subject to backup withholding in respect of amounts paid to the Non-U.S. Holder, unless such Non-U.S. Holder complies with certification procedures to establish that it is not a U.S. person for U.S. federal income tax purposes or otherwise establishes an exemption. Compliance with the certification procedures described above under "―Tax Treatment upon Sale, Exchange or Settlement of the securities - Certification Requirement" will satisfy the certification requirements necessary to avoid backup withholding as well. The amount of any backup withholding from a payment to a Non-U.S. Holder will be allowed as a credit against the Non-U.S. Holder's U.S. federal income tax liability and may entitle the Non-U.S. Holder to a refund, provided that the required information is timely furnished to the IRS.

FATCA

Legislation commonly referred to as "FATCA" generally imposes a withholding tax of 30% on payments to certain non-U.S. entities (including financial intermediaries) with respect to certain financial instruments, unless various U.S. information reporting and due diligence requirements have been satisfied. An intergovernmental agreement between the United States and the non-U.S. entity's jurisdiction may modify these requirements. FATCA generally applies to certain financial instruments that are treated as paying U.S.-source interest or other U.S.-source "fixed or determinable annual or periodical" income ("FDAP income"). If the securities were recharacterized as debt instruments, FATCA would apply to any payment of amounts treated as interest and to payments of gross proceeds of the disposition (including upon retirement) of the securities. However, under proposed regulations (the preamble to which specifies that taxpayers are permitted to rely on them pending finalization), no withholding will apply on payments of gross proceeds (other than amounts treated as FDAP income). If withholding were to apply to the securities, we would not be required to pay any additional amounts with respect to amounts withheld. Both U.S. and Non-U.S. Holders should consult their tax advisers regarding the potential application of FATCA to the securities.

The discussion in the preceding paragraphs under "United States Federal Taxation," insofar as it purports to describe provisions of U.S. federal income tax laws or legal conclusions with respect thereto, constitutes the full opinion of Davis Polk & Wardwell LLP regarding the material U.S. federal income tax consequences of an investment in the securities.

Use of proceeds and hedging:

The proceeds from the sale of the securities will be used by us for general corporate purposes. We will receive, in aggregate, $1,000 per security issued, because, when we enter into hedging transactions in order to meet our obligations under the securities, our hedging counterparty will reimburse the cost of the agent's commissions. The costs of the securities borne by you and described beginning on page 5 above comprise the agent's commissions and the cost of issuing, structuring and hedging the securities.

On or prior to the pricing date, we will hedge our anticipated exposure in connection with the securities by entering into hedging transactions with our affiliates and/or third-party dealers. We expect our hedging counterparties to take positions in the futures contract, in the stocks constituting the reference index, in futures and/or options contracts on the reference index or the stocks constituting the reference index listed on major securities markets, or positions in any other available securities or instruments that they may wish to use in connection with such hedging. Such purchase activity could potentially increase the initial index value, and, as a result, increase the value at or above which the underlying index must close on the final observation date so that you are not exposed to the negative performance of the underlying index at maturity. These entities may be unwinding or adjusting hedge positions during the term of the securities, and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the final observation date approaches. Additionally, our hedging activities, as well as our other trading activities, during the term of the securities could potentially affect the value of the underlying index on the final observation date, and, accordingly, the amount of cash you will receive at maturity.

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; conflicts of interest:

MS & Co. expects to sell all of the securities that it purchases from us to an unaffiliated dealer at a price of $ per security, for further sale to certain fee-based advisory accounts at the price to public of $1,000 per security. MS & Co. will not receive a sales commission with respect to the securities.

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 securities. When MS & Co. prices this offering of securities, it will determine the economic terms of the securities, including the redemption payment amounts, such that for each security the estimated value on the pricing date will be no lower than the minimum level described in "Investment Summary" beginning on page 4.

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.

In order to facilitate the offering of the securities, the agent may engage in transactions that stabilize, maintain or otherwise affect the price of the securities. Specifically, the agent may sell more securities than it is obligated to purchase in connection with the offering, creating a naked short position in the securities, for its own account. The agent must close out any naked short position by purchasing the securities in the open market. A naked short position is more likely to be created if the agent is concerned that there may be downward pressure on the price of the securities in the open market after pricing that could adversely affect investors who purchase in the offering. As an additional means of facilitating the offering, the agent may bid for, and purchase, the securities or the securities underlying the underlying index in the open market to stabilize the price of the securities. Any of these activities may raise or maintain the market price of the securities above independent market levels or prevent or retard a decline in the market price of the securities. The agent is not required to engage in these activities, and may end any of these activities at any time. An affiliate of the agent has entered into a hedging transaction with us in connection with this offering of securities. See "Plan of Distribution (Conflicts of Interest)" in the accompanying prospectus supplement and "Use of Proceeds and Hedging" above.
