Aggregate principal amount:

$

Stated principal amount:

$1,000 per security

Issue price:

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

Maturity date:

December 2, 2026

Call feature:

Beginning on May 30, 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 underlying stock 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 27.75% (corresponding to approximately $23.125 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 either underlying stock is less than the respective coupon barrier level, no contingent monthly coupon will be paid with respect to that observation date. It is possible that one or both underlying stocks 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 underlying stock is greater than or equal to 60% of its respective initial share price, meaning that neither underlying stock has decreased by an amount greater than the buffer amount of 40% from its respective initial share price:

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

If the final share price of either underlying stock is less than 60% of its respective initial share price, meaning that either underlying stock has decreased by an amount greater than the buffer amount of 40% from its respective initial share price:

$1,000 + [$1,000 × (share percent change of the worst performing underlying stock + 40%) × downside factor]

Under these circumstances, the payment at maturity will be less than the stated principal amount of $1,000 and could be zero.

Maturity:

2 years, unless redeemed earlier based on the output of a risk neutral valuation model

Contingent monthly coupon:

If, on any observation date, the determination closing price of each underlying stock 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 27.75% (corresponding to approximately $23.125 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 either underlying stock is less than the respective coupon barrier level, no contingent monthly coupon will be paid with respect to that observation date. It is possible that one or both underlying stocks 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 May 30, 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 stocks. 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 underlying stock 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 either underlying stock is below its respective coupon barrier level and/or when the final share price of either underlying stock is expected to have declined from its respective initial share price by an amount greater than the buffer amount, such that you will receive no contingent monthly coupons and/or that you will suffer a 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 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 underlying stock is greater than or equal to 60% of its respective initial share price, meaning that neither underlying stock has decreased by an amount greater than the buffer amount of 40% from its respective initial share price:

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

If the final share price of either underlying stock is less than 60% of its respective initial share price, meaning that either underlying stock has decreased by an amount greater than the buffer amount of 40% from its respective initial share price:

$1,000 + [$1,000 × (share percent change of the worst performing underlying stock + 40%) × downside factor]

Under these circumstances, the payment at maturity will be less than the stated principal amount of $1,000 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 May 30, 2025, six months after the original issue date, 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 underlying stock 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 of both underlying stocks close 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 underlying stock closes at or above its respective coupon barrier level on some monthly observation dates, but one or both underlying stocks close below the respective coupon barrier level(s) on the others. Investors will receive the contingent monthly coupon for the monthly periods for which the determination closing price of each underlying stock is at or above its respective coupon barrier level on the related observation date, but not for the monthly periods for which one or both underlying stocks close below the respective coupon barrier level(s) on the related observation date. On the final observation date, neither underlying stock has declined from its initial share price by an amount greater than the buffer amount. At maturity, investors receive the stated principal amount and, if the final share price of each underlying stock is also greater than or equal to its 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 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 both underlying stocks close below the respective coupon barrier level(s) on every monthly observation date. Since one or both underlying stocks close 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 both underlying stocks have declined from the respective initial share price(s) by an amount greater than the buffer amount. At maturity, investors will lose 1.6667% for every 1% decline of the worst performing underlying stock beyond the specified buffer amount. Investors will lose some, and may lose up to all, of the stated principal amount of the securities in this scenario.

Hypothetical Contingent Monthly Coupon:

If, on any observation date, the determination closing price of each underlying stock is greater than or equal to its respective coupon barrier level, we will pay a contingent monthly coupon at an annual rate of 27.75% (corresponding to approximately $23.125 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 either underlying stock is less than the respective coupon barrier level, no contingent monthly coupon will be paid with respect to that observation date. It is possible that one or both underlying stocks 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 May 30, 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 underlying stock is greater than or equal to 60% of its respective initial share price, meaning that neither underlying stock has decreased by an amount greater than the buffer amount of 40% from its respective initial share price:

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

If the final share price of either underlying stock is less than 60% of its respective initial share price, meaning that either underlying stock has decreased by an amount greater than the buffer amount of 40% from its respective initial share price:

$1,000 + [$1,000 × (share percent change of the worst performing underlying stock +40%) × downside factor]

Under these circumstances, the payment at maturity will be less than the stated principal amount of $1,000 and could be zero.

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", "Antidilution adjustments," and "Alternate exchange calculation in case of an event of default" 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.

Trading day:

With respect to each underlying stock, a day, as determined by the calculation agent, on which trading is generally conducted on the New York Stock Exchange, The Nasdaq Stock Market LLC (the "Nasdaq"), the Chicago Mercantile Exchange and the Chicago Board of Options Exchange and in the over-the-counter market for equity securities in the United States.

Closing price:

Subject to the provisions set out under "Antidilution adjustments" below, the closing price for one share of an underlying stock (or one unit of any other security for which a closing price must be determined) on any trading day means:

(i) if an underlying stock (or any such other security) is listed on a national securities exchange (other than 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 stock (or any such other security) is listed,

(ii) if an underlying stock (or any such other security) is a security of the Nasdaq, the official closing price of such underlying stock published by the Nasdaq on such day, or

(iii) if an underlying stock (or any such other security) is not listed on any national securities exchange but is 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.

If an underlying stock (or any such other security) is 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 stock (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 such underlying stock, (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 stock (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 stock (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, the closing price of such underlying stock 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 "Antidilution adjustments" below.

Market disruption event:

With respect to any underlying stock, market disruption event means:

(i) the occurrence or existence of any of:

(a)a suspension, absence or material limitation of trading of such underlying stock on the primary market for such underlying stock 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

(b)a breakdown or failure in the price and trade reporting systems of the primary market for such underlying stock as a result of which the reported trading prices for such underlying stock during the last one-half hour preceding the close of the principal trading session in such market are materially inaccurate; or

(c)the suspension, absence or material limitation of trading on the primary market for trading in futures or options contracts related to such underlying stock, 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; 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 purposes of determining whether a market disruption event has occurred with respect to an underlying stock: (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 primary market, (2) a decision to permanently discontinue trading in the relevant options contract will not constitute a market disruption event, (3) a suspension of trading in options contracts on such underlying stock 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 options contracts related to such underlying stock and (4) a suspension, absence or material limitation of trading on the primary market on which options contracts related to such underlying stock are traded will not include any time when such securities market is itself closed for trading under ordinary circumstances.

Postponement of observation dates:

The observation dates are subject, independently in the case of each underlying stock, 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 underlying stock occurs on any scheduled observation date, or if any such observation date is not a trading day with respect to any underlying stock, the closing price for that underlying stock for such date will be determined on the immediately succeeding trading day on which no market disruption event will have occurred with respect to that underlying stock; provided that the determination closing price for an underlying stock 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 such affected underlying stock on such fifth trading day based on the mean, as determined by the calculation agent, of the bid prices for one share of such underlying stock 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 for such underlying stock 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.

Postponement of coupon payment dates (including the

If any scheduled coupon payment date is not a business day, that contingent monthly coupon, if any, shall be paid on the next succeeding business day; provided that the contingent monthly coupon, if any, with respect

maturity date and redemption dates):

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 either underlying stock 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 and no adjustment shall be made to any contingent monthly coupon payment, payment at maturity or redemption payment made on that postponed date.

Antidilution adjustments:

The adjustment factor with respect to an underlying stock will be adjusted as follows:

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

2. If an underlying stock is subject (i) to a stock dividend (issuance of additional shares of such underlying stock) that is given ratably to all holders of shares of such underlying stock or (ii) to a distribution of such underlying stock as a result of the triggering of any provision of the corporate charter of the issuer of such underlying stock (the relevant "underlying stock issuer") then once the dividend has become effective and such underlying stock is trading ex-dividend, the adjustment factor for such underlying stock will be adjusted so that the new adjustment factor for such underlying stock will equal the prior adjustment factor for such underlying stock plus the product of (i) the number of shares issued with respect to one share of such underlying stock and (ii) the prior adjustment factor for such underlying stock.

3. If an underlying stock issuer issues rights or warrants to all holders of its underlying stock to subscribe for or purchase that underlying stock at an exercise price per share less than the closing price of that underlying stock on both (i) the date the exercise price of such rights or warrants is determined and (ii) the expiration date of such rights or warrants, and if the expiration date of such rights or warrants precedes the maturity of the securities, then the adjustment factor for such underlying stock will be adjusted to equal the product of the prior adjustment factor for such underlying stock and a fraction, the numerator of which will be the number of shares of such underlying stock outstanding immediately prior to the issuance of such rights or warrants plus the number of additional shares of such underlying stock offered for subscription or purchase pursuant to such rights or warrants and the denominator of which will be the number of shares of such underlying stock outstanding immediately prior to the issuance of such rights or warrants plus the number of additional shares of such underlying stock which the aggregate offering price of the total number of shares of such underlying stock so offered for subscription or purchase pursuant to such rights or warrants would purchase at the closing price on the expiration date of such rights or warrants, which will be determined by multiplying such total number of shares offered by the exercise price of such rights or warrants and dividing the product so obtained by such closing price.

4. There will be no required adjustments to the adjustment factors to reflect cash dividends or other distributions paid with respect to an underlying stock other than distributions described in paragraph 2, paragraph 3 and clauses (i), (iv) and (v) of paragraph 5 below and extraordinary dividends as described below. A cash dividend or other distribution with respect to such underlying stock will be deemed to be an extraordinary dividend if such cash dividend or distribution exceeds the immediately preceding non-extraordinary dividend for such underlying stock by an amount equal to at least 10% of the closing price of such underlying stock (as adjusted for any subsequent corporate event requiring an adjustment hereunder, such as a stock split or reverse stock split) on the trading day preceding the ex-dividend date (that is, the day on and after which transactions in such underlying stock on the primary U.S. organized securities exchange or trading system on which such underlying stock is traded no longer carry the right to receive that cash dividend or that cash distribution) for the payment of such extraordinary dividend. If an extraordinary dividend occurs with respect to such underlying stock, the adjustment factor with respect to such underlying stock will be adjusted on the ex-dividend date with respect to such extraordinary dividend so that the new adjustment factor with respect to such underlying stock will equal the product of (i) the then current adjustment factor with respect to such underlying stock and (ii) a fraction, the numerator of which is the closing price on the trading day preceding the ex-dividend date, and the denominator of which is the amount by which the closing price on the trading day preceding the ex-dividend date exceeds the extraordinary dividend amount. The extraordinary dividend amount with respect to an extraordinary dividend for such underlying stock will equal (i) in the case of cash dividends or other distributions that constitute regular dividends, the amount per share of such extraordinary dividend minus the amount per share of the immediately preceding non-extraordinary dividend for such underlying stock or (ii) in the case of cash dividends or other distributions that do not constitute regular dividends, the amount per share of such extraordinary dividend. To the extent an extraordinary dividend is not paid in cash, the value of the non-cash component will be determined by the calculation agent, whose determination will be conclusive. A distribution on such underlying stock described in clause (i), (iv) or (v) of paragraph 5 below that also constitutes an extraordinary dividend will cause an adjustment to the adjustment factor for such underlying stock pursuant only to clause (i), (iv) or (v) of paragraph 5, as applicable.

5. If, with respect to one or both of the underlying stocks, (i) there occurs any reclassification or change of such underlying stock, including, without limitation, as a result of the issuance of any tracking stock by the underlying stock issuer for such underlying stock, (ii) such underlying stock issuer or any surviving entity or subsequent surviving entity of such underlying stock issuer (the "successor corporation") has been subject to a merger, combination or consolidation and is not the surviving entity, (iii) any statutory exchange of securities of such

underlying stock issuer or any successor corporation with another corporation occurs (other than pursuant to clause (ii) above), (iv) such underlying stock issuer is liquidated, (v) such underlying stock issuer issues to all of its shareholders equity securities of an issuer other than such underlying stock issuer (other than in a transaction described in clause (ii), (iii) or (iv) above) (a "spin-off event") or (vi) a tender or exchange offer or going-private transaction is consummated for all the outstanding shares of such underlying stock (any such event in clauses (i) through (vi), a "reorganization event"), the method of determining the amount payable upon a redemption date or at maturity for each security will be as follows:

●Upon the final observation date, if the securities have not previously been redeemed: You will receive for each security that you hold a payment at maturity equal to:

➢If the exchange property value on the final observation date is greater than or equal to 60% of the respective initial share price, and the final share price of the other underlying stock (or exchange property value, as applicable) is also greater than or equal to 60% of the respective initial share price: the stated principal amount and, if the exchange property value on the final observation date is also greater than or equal to the respective coupon barrier level, and the final share price of the other underlying stock (or exchange property value, as applicable) 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 exchange property value on the final observation date is less than 60% of the respective initial share price, or if the final share price (or exchange property value, as applicable) of the other underlying stock is less than 60% of the respective initial share price:

oIf the worst performing underlying stock has not undergone a reorganization event as described in paragraph 5 above: $1,000 + [$1,000 × (share percent change of the worst performing underlying stock + 40%) × downside factor]

oIf the worst performing underlying stock has undergone a reorganization event as described in paragraph 5 above: $1,000 + [$1,000 × (share percent change of the worst performing underlying stock + 40%) × downside factor]. For purposes of determining the share performance factor of the worst performing underlying stock, the final share price of such worst performing underlying stock shall be deemed to equal the per-share cash value, determined as of the final observation date, of the securities, cash or any other assets distributed to holders of the worst performing underlying stock in or as a result of any such reorganization event, including (A) in the case of the issuance of tracking stock, the reclassified share of such worst performing underlying stock, (B) in the case of a spin-off event, the share of such worst performing underlying stock with respect to which the spun-off security was issued, and (C) in the case of any other reorganization event where such worst performing underlying stock continues to be held by the holders receiving such distribution, such worst performing underlying stock (collectively, the "exchange property"), per share of such worst performing underlying stock multiplied by the adjustment factor for such worst performing underlying stock on the final observation date.

Following the effective date of a reorganization event, the contingent monthly coupon will be payable for each observation date on which the exchange property value is greater than or equal to the coupon barrier level and the determination closing price (or exchange property value, as applicable) of the other underlying stock is also greater than or equal to the respective coupon barrier level.

If exchange property includes a cash component, investors will not receive any interest accrued on such cash component. In the event exchange property consists of securities, those securities will, in turn, be subject to the antidilution adjustments set forth in paragraphs 1 through 5.

For purposes of determining whether or not the exchange property value is less than the initial share price, or less than the coupon barrier level, or for determining the worst performing underlying stock, "exchange property value" means (x) for any cash received in any reorganization event, the value, as determined by the calculation agent in its sole discretion, as of the date of receipt, of such cash received for one share of such underlying stock, as adjusted by the adjustment factor at the time of such reorganization event, (y) for any property other than cash or securities received in any such reorganization event, the market value, as determined by the calculation agent in its sole discretion, as of the date of receipt, of such exchange property received for one share of such underlying stock, as adjusted by the adjustment factor at the time of such reorganization event and (z) for any security received in any such reorganization event, an amount equal to the determination closing price, as of the day on which the exchange property value is determined, per share of such security multiplied by the quantity of such security received for each share of such underlying stock, as adjusted by the adjustment factor at the time of such reorganization event.

For purposes of paragraph 5 above, in the case of a consummated tender or exchange offer or going-private transaction involving consideration of particular types, exchange property shall be deemed to include the amount of cash or other property delivered by the offeror in the tender or exchange offer (in an amount determined on the basis of the rate of exchange in such tender or exchange offer or going-private transaction). In the event of a tender or exchange offer or a going-private transaction with respect to exchange property in which an offeree may elect to

receive cash or other property, exchange property shall be deemed to include the kind and amount of cash and other property received by offerees who elect to receive cash.

Following the occurrence of any reorganization event referred to in paragraph 5 above, all references herein to such "underlying stock" shall be deemed to refer to the exchange property and references to a "share" or "shares" of such underlying stock shall be deemed to refer to the applicable unit or units of such exchange property, unless the context otherwise requires.

No adjustment to the adjustment factor will be required unless such adjustment would require a change of at least 0.1% in the adjustment factor then in effect. The adjustment factor resulting from any of the adjustments specified above will be rounded to the nearest one hundred-thousandth, with five one-millionths rounded upward. Adjustments to the adjustment factor will be made up to the close of business on the final observation date.

No adjustments to the adjustment factor or method of calculating the adjustment factor will be required other than those specified above. The adjustments specified above do not cover all events that could affect the determination closing price or the final share price of such underlying stock, including, without limitation, a partial tender or exchange offer for such underlying stock.

The calculation agent shall be solely responsible for the determination and calculation of any adjustments to the adjustment factor or method of calculating the adjustment factor and of any related determinations and calculations with respect to any distributions of stock, other securities or other property or assets (including cash) in connection with any corporate event described in paragraphs 1 through 5 above, and its determinations and calculations with respect thereto shall be conclusive in the absence of manifest error.

The calculation agent will provide information as to any adjustments to an adjustment factor or to the method of calculating the amount payable at maturity of the securities made pursuant to paragraph 5 above upon written request by any investor in the securities.

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, if any, amount due 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.

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 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 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 interest to the trustee for delivery to the depositary, as holder of the securities, on the applicable coupon payment date.

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:

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.

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.

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.

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"). 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 4 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 stocks, in futures and/or options contracts on the underlying stocks, 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 an underlying stock, and, as a result, increase (i) the coupon barrier level for such underlying stock, which, if the securities have not been redeemed, is the level at or above which such underlying stock 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 stock), and (ii) the level at or above which such underlying stock must close on the final observation date so that you are not exposed to the negative performance of the worst performing underlying stock at maturity (depending also on the performance of the other underlying stock). 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 stock 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 stock).

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 3.

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 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.
