Issue price:

$1,000 per security (see "Commissions and issue price" below)

Call feature:

Beginning on February 12, 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.

Contingent monthly coupon:

If, on any observation date, the determination closing price of each of the underlying shares is greater than or equal to its respective coupon barrier level, we will pay a contingent monthly coupon at an annual rate of at least 15.40% (corresponding to approximately $12.833 per month per security) on the related contingent coupon payment date. The actual contingent monthly coupon rate will be determined on the pricing date.

If, on any observation date, the determination closing price of any of the underlying sharesis less than the coupon barrier level for such underlying shares, no contingent monthly coupon will be paid with respect to that observation date. It is possible that one or more of the underlying shares will remain below the respective coupon barrier level(s) for extended periods of time or even throughout the entire term of the securities so that you will receive few or no contingent monthly coupons.

Payment at maturity:

If the securities have not previously been redeemed, investors will receive on the maturity date a payment at maturity determined as follows:

If the final share price of each of the underlying shares is greater than or equal to its respective downside threshold level: the stated principal amount and, if the final share price of each of the underlying shares is also greater than or equal to the respective coupon barrier level, the contingent monthly coupon with respect to the final observation date.

If the final share price of any of the underlying shares is less than its respective downside threshold level: (i) the stated principal amount multiplied by (ii) the share performance factor of the worst performing underlying shares. Under these circumstances, the payment at maturity will be less than 65% of the stated principal amount of the securities and could be zero.

Contingent monthly coupon:

If, on any observation date, the determination closing price of each of the underlying sharesis greater than or equal to its respective coupon barrier level, we will pay a contingent monthly coupon at an annual rate of at least 15.40% (corresponding to approximately $12.833 per month per security) on the related contingent coupon payment date. The actual contingent monthly coupon rate will be determined on the pricing date.

If, on any observation date, the determination closing price of any of the underlying shares is less than the coupon barrier level for such underlying shares, no contingent monthly coupon will be paid with respect to that observation date. It is possible that one or more of the underlying shares will remain below the respective coupon barrier level(s) for extended periods of time or even throughout the entire term of the securities so that you will receive few or no contingent monthly coupons.

Early redemption:

Beginning on February 12, 2025, we will redeem the securities on any quarterly redemption date for an early redemption payment equal to the stated principal amount plus any contingent monthly coupon otherwise due with respect to the related observation 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" on the cover page, 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 shares. 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 determination closing price of each of the underlying shares on the observation dates is at or above its respective coupon barrier level, which would otherwise result in an amount of interest payable on the securities that is greater than instruments of a comparable maturity and credit rating trading in the market. In other words, we will be more likely to redeem the securities at a time when the securities are paying an above-market coupon. If the securities are redeemed prior to maturity, you will receive no more contingent monthly coupon payments, may be forced to invest in a lower interest rate environment and may not be able to reinvest at comparable terms or returns.

On the other hand, we will be less likely to redeem the securities when the determination closing price of any of the underlying shares is below its respective coupon barrier level and/or when the final share price of any of the underlying shares is expected to be below the downside threshold level, such that you will receive no contingent monthly coupons and/or 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 receive few or no contingent monthly coupons and suffer a significant loss at maturity.

Payment at maturity:

If the securities have not previously been redeemed, investors will receive on the maturity date a payment at maturity determined as follows:

If the final share price of each of the underlying shares is greater than or equal to its respective downside threshold level: the stated principal amount and, if the final share price of each of the underlying shares is also greater than or equal to the respective coupon barrier level, the contingent monthly coupon with respect to the final observation date.

If the final share price of any of the underlying shares is less than its respective downside threshold level: (i) the stated principal amount multiplied by (ii) the share performance factor of the worst performing underlying shares. Under these circumstances, the payment at maturity will be less than 65% of the stated principal amount of the securities and could be zero.

Scenario 1: The securities are redeemed prior to maturity.

This scenario assumes that the securities are redeemed prior to the maturity date on one of the quarterly redemption dates, starting on February 12, 2025, based on the output of a risk neutral valuation model, for the redemption payment equal to the stated principal amount plus any contingent monthly coupon with respect to the relevant observation date, as applicable. Prior to the early redemption, each of the underlying shares closes at or above its respective coupon barrier level on some or all of the monthly observation dates. In this scenario, investors receive the contingent monthly coupon with respect to each such observation date, but not for the monthly periods for which one or more of the underlying shares close(s) below the respective coupon barrier level on the related observation date. 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 investors receive principal back at maturity.

This scenario assumes that the securities are not redeemed on any of the quarterly redemption dates, and, as a result, investors hold the securities to maturity. During the term of the securities, each of the underlying shares closes at or above its respective coupon barrier level on some monthly observation dates, but one or more of the underlying shares close(s) below the respective coupon barrier level(s) for such underlying shares on the others. Investors will receive the contingent monthly coupon for the monthly periods for which the determination closing price of each of the underlying shares is at or above its respective coupon barrier level on the related observation date, but not for the monthly periods for which one or more of the underlying shares close(s) below the respective coupon barrier level(s) on the related observation date. On the final observation date, each of the underlying shares closes at or above its downside threshold level. At maturity, investors receive the stated principal amount and, if the final share price of each of the underlying shares is also greater than or equal to the respective coupon barrier level, the contingent monthly coupon with respect to the final observation date.

Scenario 3: The securities are not redeemed prior to maturity, and investors suffer a substantial loss of principal at maturity.

This scenario assumes that the securities are not redeemed on any of the quarterly redemption dates, and, as a result, investors hold the securities to maturity. During the term of the securities, one or more of the underlying shares close(s) below the respective coupon barrier level(s) on every monthly observation date. Since one or more of the underlying shares close(s) below the respective coupon barrier level(s) on every monthly observation date, investors do not receive any contingent monthly coupon. On the final observation date, one or more of the underlying shares close(s) below the respective downside threshold level(s). At maturity, investors will receive an amount equal to the stated principal amount multiplied by the share performance factor of the worst performing underlying shares. Under these circumstances, the payment at maturity will be less than 65% of the stated principal amount and could be zero.

Hypothetical Contingent Monthly Coupon:

If, on any observation date, the determination closing price of each of the underlying shares is greater than or equal to its respective coupon barrier level, we will pay a contingent monthly coupon at an annual rate of 15.40% (corresponding to approximately $12.833 per month per security*) on the related contingent coupon payment date. The actual contingent monthly coupon rate will be determined on the pricing date.

If, on any observation date, the determination closing price of any of the underlying sharesis less than the coupon barrier level for such underlying shares, no contingent monthly coupon will be paid with respect to that observation date. It is possible that one or more of the underlying shares will remain below the respective coupon barrier level(s) for extended periods of time or even throughout the entire term of the securities so that you will receive few or no contingent monthly coupons.

Call Feature:

Beginning on February 12, 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. Any redemption payment will be equal to the stated principal amount plus any contingent monthly coupon otherwise due with respect to the related observation date. If the securities are redeemed prior to maturity, you will receive no more contingent monthly coupon payments, may be forced to invest in a lower interest rate environment and may not be able to reinvest at comparable terms or returns.

Payment at Maturity (if the securities have not been redeemed early):

If the final share price of each of the underlying shares is greater than or equal to its respective downside threshold level: the stated principal amount and, if the final share price of each of the underlying shares is also greater than or equalto the respective coupon barrier level, the contingent monthly coupon with respect to the final observation date.

If the final share price of any of the underlying shares is less than its respective downside threshold level: (i) the stated principal amount multiplied by (ii) the share performance factor of the worst performing underlying shares. Under these circumstances, the payment at maturity will be less than 65% of the stated principal amount of the securities and could be zero.

Interest will be computed on the basis of a 360-day year of twelve 30-day months.

Postponement of observation dates:

The observation dates are subject to postponement due to non-trading days or certain market disruption events, as described in the following paragraph.

If a market disruption event with respect to any of the underlying shares occurs on any scheduled observation date, or if any such observation date is not a trading day, the closing price solely for such underlying shares for such date will be determined on the immediately succeeding trading day on which no market disruption event will have occurred with respect to such affected underlying shares; provided that the determination closing price for any of the underlying shares will not be determined on a date later than the fifth scheduled trading day after the scheduled observation date and if such date is not a trading day, or if there is a market disruption event on such date, the calculation agent will determine the closing price of the affected underlying shares on such fifth trading day based on the mean, as determined by the calculation agent, of the bid prices for such underlying shares for such date obtained from as many recognized dealers in such security, but not exceeding three, as will make such bid prices available to the calculation agent. Bids of MS & Co. or any of its affiliates may be included in the calculation of such mean, but only to the extent that any such bid is the highest of the bids obtained. If no bid prices are provided from any third-party dealers, the closing price will be determined by the calculation agent in its sole and absolute discretion (acting in good faith) taking into account any information that it deems relevant.

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

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.

Closing price:

Subject to the provisions set out under "Discontinuance of the underlying shares and/or the share underlying indices; alteration of method of calculation" below, the closing price for one share of an underlying shares (or one unit of any other security for which a closing price must be determined) on any trading day means:

(i)if such underlying shares (or any such other security) are listed on a national securities exchange (other than the Nasdaq), the last reported sale price, regular way, of the principal trading session on such day on the principal national securities exchange registered under the Securities Exchange Act of 1934, as amended, on which such underlying shares (or any such other security) are listed,

(ii)if such underlying shares (or any such other security) are securities of the Nasdaq, the official closing price of such underlying shares published by the Nasdaq on such day, or

(iii)if such underlying shares (or any such other security) are not listed on any national securities exchange but are included in the OTC Bulletin Board Service (the "OTC Bulletin Board") operated by the Financial Industry Regulatory Authority, Inc. ("FINRA"), the last reported sale price of the principal trading session on the OTC Bulletin Board on such day for such underlying shares.

If such underlying shares (or any such other security) are listed on any national securities exchange but the last reported sale price or the official closing price published by such exchange, or by the Nasdaq, as applicable, is not available pursuant to the preceding sentence, then the closing price for one share of such underlying shares (or one unit of any such other security) on any trading day will mean the last reported sale price of the principal trading session on the over-the-counter market as reported on the Nasdaq or the OTC Bulletin Board on such day. If a market disruption event (as defined below) occurs with respect to any of the underlying shares (or any such other security) or the last reported sale price or the official closing price published by the Nasdaq, as applicable, for such underlying shares (or any such other security) is not available pursuant to either of the two preceding sentences, then the closing price for any trading day will be the mean, as determined by the calculation agent, of the bid prices for such underlying shares (or any such other security) for such trading day obtained from as many recognized dealers in such security, but not exceeding three, as will make such bid prices available to the calculation agent. Bids of MS & Co. and its successors or any of its affiliates may be included in the calculation of such mean, but only to the extent that any such bid is the highest of the bids obtained. If no bid prices are provided from any third-party dealers, such closing price will be determined by the calculation agent in its sole and absolute discretion (acting in good faith) taking into account any information that it deems relevant. The term "OTC Bulletin Board Service" will include any successor service thereto, or, if applicable, the OTC Reporting Facility operated by FINRA. See "Discontinuance of the underlying shares and/or the share underlying indices; alteration of method of calculation" below.

Market disruption event:

With respect to each of the underlying shares, market disruption event means:

(i) the occurrence or existence of any of:

(a) a suspension, absence or material limitation of trading of such underlying shares on the primary market for such underlying shares for more than two hours of trading or during the one-half hour period preceding the close of the principal trading session in such market; or a breakdown or failure in the price and trade reporting systems of the primary market for such underlying shares as a result of which the reported trading prices for such underlying shares during the last one-half hour preceding the close of the principal trading session in such market are materially inaccurate; or the suspension, absence or material limitation of trading on the primary market for trading in futures or options contracts related to such underlying shares, if available, during the one-half hour period preceding the close of the principal trading session in the applicable market, in each case as determined by the calculation agent in its sole discretion; or

(b) a suspension, absence or material limitation of trading of stocks then constituting 20 percent or more of the value of the share underlying index for such underlying shares 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), in each case as determined by the calculation agent in its sole discretion; or

(c) the suspension, material limitation or absence of trading on any major U.S. securities market for trading in futures or options contracts related to the share underlying index for such underlying shares or the underlying shares 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, if trading in a security included in the share underlying index for an underlying shares is materially suspended or materially limited at that time, then the relevant percentage contribution of that security to the level of the share underlying index for such underlying shares will be based on a comparison of (x) the portion of the level of the share underlying index for such underlying shares attributable to that security relative to (y) the overall level of the share underlying index for such underlying shares, in each case immediately before that suspension or limitation.

For the purpose of determining whether a market disruption event has occurred with respect to the underlying shares: (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 an underlying shares or in the futures or options contract related to the share underlying index for an underlying shares or an underlying shares will not constitute a market disruption event, (3) a suspension of trading in futures or options contracts on the share underlying index for an underlying shares or an underlying shares by the primary securities market trading in such contracts 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 (c) a disparity in bid and ask quotes relating to such contracts will constitute a suspension, absence or material limitation of trading in futures or options contracts related to the share underlying index for an underlying shares or an underlying shares 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 related to the share underlying index for an underlying shares or an underlying shares are traded will not include any time when such securities market is itself closed for trading under ordinary circumstances. Regarding any permanent discontinuance of trading in an underlying shares, see "Discontinuance of the underlying shares and/or the share underlying indices; alteration of method of calculation" below.

Discontinuance of the underlying shares and/or the share underlying indices; alteration of method of calculation:

If trading in an underlying shares on every applicable national securities exchange, on the OTC Bulletin Board and in the over-the-counter market is permanently discontinued or the SPDR® S&P® Regional Banking ETF, the iShares® U.S. Real Estate ETF or the Financial Select Sector SPDR® Fund is liquidated or otherwise terminated (a "discontinuance or liquidation event"), the closing price of such underlying shares on any trading day following the discontinuance or liquidation event will be determined by the calculation agent and will be deemed to equal the product of (i) the closing value of the share underlying index for such underlying shares (or any successor index, as described below) on such date (taking into account any material changes in the method of calculating the share underlying index for such underlying shares following such discontinuance or liquidation event) and (ii) a fraction, the numerator of which is the closing price of such underlying shares and the denominator of which is the closing value of the share underlying index for such underlying shares (or any successor index, as described below), each determined as of the last day prior to the occurrence of the discontinuance or liquidation event on which a closing price was available.

If, subsequent to a discontinuance or liquidation event, the relevant share underlying index publisher discontinues publication of the share underlying index for such underlying shares and the relevant share 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 share underlying index for such underlying shares (such index being referred to herein as a "successor index"), then any subsequent closing price for such underlying shares on any trading day following a discontinuance or liquidation event will be determined by reference to the published value of such successor index at the regular weekday close of trading on such trading day, and, to the extent the value of the successor index differs from the value of the share underlying index for such underlying shares at the time of such substitution, proportionate adjustments shall be made by the calculation agent for purposes of calculating payments on the securities.

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, subsequent to a discontinuance or liquidation event, the relevant share underlying index publisher discontinues publication of the share underlying index for such underlying shares prior to, and such discontinuance is continuing on, an 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 closing price for such underlying shares for such date. Such closing price will be computed by the calculation agent in accordance with the formula for and method of calculating such share underlying

index for such underlying shares 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 composing the share underlying index for such underlying shares without any rebalancing or substitution of such securities following such discontinuance.

Antidilution adjustments:

The adjustment factor with respect to each of the underlying shares shall be adjusted as follows:

If such underlying shares are subject to a stock split or reverse stock split, then once such split has become effective, the adjustment factor for such underlying shares will be adjusted by the calculation agent to equal the product of the prior adjustment factor and the number of shares issued in such stock split or reverse stock split with respect to one share of such underlying shares.

No adjustment to an adjustment factor pursuant to the paragraph above will be required unless such adjustment would require a change of at least 0.1% in the amount being adjusted as then in effect. Any number so adjusted will be rounded to the nearest one hundred-thousandth with five one-millionths being rounded upward.

The calculation agent will be solely responsible for the determination and calculation of any adjustments to the adjustment factors or method of calculating the adjustment factors and of any related determinations, and its determinations and calculations with respect thereto will be conclusive in the absence of manifest error.

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.

Trustee:

The Bank of New York Mellon, a New York banking corporation

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 contingent monthly coupon, the redemption payment and the payment at maturity, if any, 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, if any, on each coupon payment date, upon early redemption or at maturity or whether a market disruption event has occurred. See "Market disruption event," "Discontinuance of the underlying shares and/or the share underlying indices; alteration of method of calculation." MS & Co. is obligated to carry out its duties and functions as calculation agent in good faith and using its reasonable judgment.

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 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.

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 to be delivered as contingent monthly coupon, if any, with respect to the securities on or prior to 10:30 a.m. (New York City time) on the business day preceding each coupon payment date, and (ii) deliver the aggregate cash amount due with respect to the applicable coupon to the trustee for delivery to the depositary, as holder of the securities, on the applicable coupon payment date.

In the event that any coupon payment date is postponed due to the postponement of the relevant observation date, the issuer shall give notice of such postponement and, once it has been determined, of the date to which the applicable coupon payment 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 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 any coupon payment date, the business day immediately preceding the applicable scheduled coupon payment date, and (ii) with respect to notice of the date to which the applicable coupon payment date has been rescheduled, the business day immediately following the applicable observation date as postponed.

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 the securities, on or prior to 10:30 a.m. (New York City time) on the business day preceding the redemption date or the business day preceding the maturity date, as applicable, 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 redemption date or maturity date, as applicable.

Additional Information:

Minimum ticketing size:

$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 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 "The Depositary" in the accompanying prospectus supplement and "Forms of Securities-Global Securities-Registered 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 document and is superseded by the following discussion.

The following is a general discussion of the material 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.

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. 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. Moreover, the discussion below does not address the consequences to taxpayers subject to special tax accounting rules under Section 451(b) of the Code.

This discussion is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations, all as of the date hereof, 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

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 IRS or a court will agree with the tax treatment described herein. We intend to treat a security for U.S. federal income tax purposes as a single financial contract that provides for a coupon that will be treated as gross income to you at the time received or accrued in accordance with your regular method of tax accounting. In the opinion of our counsel, Davis Polk & Wardwell LLP, this treatment of the securities is reasonable under current law; however, there are other reasonable treatments that the IRS or a court may adopt, in which case the timing and character of any income or loss on the securities could be materially affected. Moreover, our counsel's opinion is based on market conditions as of the date of this preliminary pricing supplement and is subject to confirmation on the pricing date.

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 each security 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 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.

Tax Treatment of Coupon Payments. Any coupon payment on the securities should be taxable as ordinary income to a U.S. Holder at the time received or accrued, in accordance with the U.S. Holder's regular method of accounting for U.S. federal income tax purposes.

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. For this purpose, the amount realized does not include any coupon paid at settlement and may not include sale proceeds attributable to an accrued coupon, which may be treated in the same manner as a coupon payment. In general, any such gain or loss recognized should be short-term capital gain or loss if the U.S. Holder has held the securities for one year or less at the time of the sale, exchange or settlement, and should be long-term capital gain or loss otherwise. The ordinary income treatment of the coupon payments, in conjunction with the capital loss treatment of any loss recognized upon the sale, exchange or settlement of the securities, could result in adverse tax consequences to holders of the securities because the deductibility of capital losses is subject to limitations.

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 any contingent payments 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 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.

We do not plan to request a ruling from the IRS regarding the treatment of the securities. Other alternative federal income tax treatments of the securities are possible, which, if applied, could significantly affect the timing and character of the income or loss with respect to the securities. In addition, the U.S. Treasury Department and the IRS have requested comments on various issues regarding the U.S. federal income tax treatment of "prepaid forward contracts" and similar financial instruments and have indicated that such transactions may be the subject of future regulations or other guidance. Furthermore, members of Congress have proposed legislative changes to the tax treatment of derivative contracts. Any legislation, Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, possibly with retroactive effect. 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 potential changes in applicable law.

Backup Withholding and Information Reporting

Backup withholding may apply in respect of payments on the securities 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 will be filed with the IRS in connection with payments 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.

Although significant aspects of the tax treatment of each security are uncertain, we intend to withhold on any coupon paid to a Non-U.S. Holder generally at a rate of 30% or at a reduced rate specified by an applicable income tax treaty under an "other income" or similar provision. We will not be required to pay any additional amounts with respect to amounts withheld. In order to claim an exemption from, or a reduction in, the 30% withholding tax, a Non-U.S. Holder of the securities must comply with certification requirements to establish that it is not a U.S. person and is eligible for such an exemption or reduction under an applicable tax treaty. If you are a Non-U.S. Holder, you should consult your tax adviser regarding the tax treatment of the securities, including the possibility of obtaining a refund of any

withholding tax and the certification requirement described 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 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 Section 871(m) 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 will be filed with the IRS in connection with any coupon payment and may be filed with the IRS in connection with the payment at maturity on the securities and the payment of proceeds from a sale, exchange or other disposition. 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. 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.

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"). Withholding (if applicable) applies to payments of U.S.-source FDAP income and to payments of gross proceeds of the disposition (including upon retirement) of certain financial instruments treated as providing for U.S.-source interest or dividends. 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). While the treatment of the securities is unclear, you should assume that any coupon payment with respect to the securities will be subject to the FATCA rules. If withholding applies to the securities, we will 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, 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 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. See also "Use of Proceeds" in the accompanying prospectus.

On or prior to the pricing date, we expect to 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 underlying shares, in futures and/or options contracts on the underlying shares or any component stocks of the share underlying indices 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 share price of one or more of the underlying shares, and, as a result, increase (i) the coupon barrier level for such underlying shares, which, if the securities have not been redeemed, is the level at or above which such underlying shares must close on each observation date in order for you to earn a contingent monthly coupon (depending also on the performance of the other underlying shares), and (ii) the downside threshold level for such underlying shares, which, if the securities are not redeemed prior to maturity, is the level at or above which such underlying shares must close on the final observation date so that you are not exposed to the negative performance of the worst performing underlying shares at maturity (depending also on the performance of the other underlying shares). 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 such underlying shares on the observation dates, and, accordingly, whether we pay a contingent monthly coupon on the securities and the amount of cash you receive at maturity, if any (depending also on the performance of the other underlying shares).

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 contingent monthly coupon rate, such that for each security the estimated value on the pricing date will be no lower than the minimum level described in "Investment Overview" 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 shares 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.
