Maturity:

Approximately 3 years

Automatic early redemption (beginning after one year):

The securities are not subject to automatic early redemption until approximately one year after the original issue date. Following this 1-year non-call period, if, on any quarterly determination date, the index closing value of each underlying index is greater than or equal to its respective call threshold level, the securities will be automatically redeemed for the applicable early redemption payment on the related early redemption date.

Early redemption payment:

The early redemption payment will be an amount in cash per stated principal amount (corresponding to a return of at least approximately 10.70% per annum) for each quarterly determination date, as follows*:

●1st determination date:

At least $1,107.00

●2nd determination date:

At least $1,133.75

●3rd determination date:

At least $1,160.50

●4th determination date:

●7th determination date:

At least $1,267.50

●8th determination date:

At least $1,294.25

*The actual early redemption payment with respect to each applicable determination date will be determined on the pricing date.

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

Payment at maturity:

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

●If the final index value of each underlying index is greater than or equal to its respective call threshold level:

At least $1,321.00 (to be determined on the pricing date)

●If the final index value of any underlying index is less than its respective call

threshold level but the final index value of each underlying index is greater than or equal to its respective downside threshold level:

$1,000

●If the final index value of any underlying index is less than its respective downside threshold level:

$1,000 × index performance factor of the worst performing underlying index

Under these circumstances, investors will lose a significant portion or all of their investment. Accordingly, investors in the securities must be willing to accept the risk of losing their entire initial investment.

The original issue price of each security is $1,000. This price includes costs associated with issuing, selling, structuring and hedging the securities, which are borne by you, and, consequently, the estimated value of the securities on the pricing date will be less than $1,000. We estimate that the value of each security on the pricing date will be approximately $956.50, or within $30.00 of that estimate. Our estimate of the value of the securities as determined on the pricing date will be set forth in the final pricing supplement.

What goes into the estimated value on the pricing date?

In valuing the securities on the pricing date, we take into account that the securities comprise both a debt component and a performance-based component linked to the underlying indices. The estimated value of the securities is determined using our own pricing and valuation models, market inputs and assumptions relating to the underlying indices, instruments based on the underlying indices, volatility and other factors including current and expected interest rates, as well as an interest rate related to our secondary market credit spread, which is the implied interest rate at which our conventional fixed rate debt trades in the secondary market.

What determines the economic terms of the securities?

In determining the economic terms of the securities, including the early redemption payment amounts, the call threshold levels and the downside threshold levels, we use an internal funding rate, which is likely to be lower than our secondary market credit spreads and therefore advantageous to us. If the issuing, selling, structuring and hedging costs borne by you were lower or if the internal funding rate were higher, one or more of the economic terms of the securities would be more favorable to you.

What is the relationship between the estimated value on the pricing date and the secondary market price of the securities?

The price at which MS & Co. purchases the securities in the secondary market, absent changes in market conditions, including those related to the underlying indices, may vary from, and be lower than, the estimated value on the pricing date, because the secondary market price takes into account our secondary market credit spread as well as the bid-offer spread that MS & Co. would charge in a secondary market transaction of this type and other factors. However, because the costs associated with issuing, selling, structuring and hedging the securities are not fully deducted upon issuance, for a period of up to 6 months following the issue date, to the extent that MS & Co. may buy or sell the securities in the secondary market, absent changes in market conditions, including those related to the underlying indices, and to our secondary market credit spreads, it would do so based on values higher than the estimated value. We expect that those higher values will also be reflected in your brokerage account statements.

MS & Co. may, but is not obligated to, make a market in the securities, and, if it once chooses to make a market, may cease doing so at any time.

Scenario 1: The securities are redeemed prior to maturity

Beginning after one year, when each underlying index closes at or above its respective call threshold level on any quarterly determination date, the securities will be automatically redeemed for the applicable early redemption payment on the related early redemption date. Investors do not participate in any appreciation in any underlying index.

Scenario 2: The securities are not redeemed prior to maturity, and investors receive a fixed positive return at maturity

This scenario assumes that any underlying index closes below its respective call threshold level on each of the quarterly determination dates (beginning after one year). Consequently, the securities are not redeemed prior to maturity. On the final determination date, each underlying index closes at or above its respective call threshold level. At maturity, investors will receive a cash payment equal to at least $1,321.00 per stated principal amount (to be determined on the pricing date). Investors do not participate in any appreciation in any underlying index.

Scenario 3: The securities are not redeemed prior to maturity, and investors receive the return of principal at maturity

This scenario assumes that any underlying index closes below its respective call threshold level on each of the quarterly determination dates (beginning after one year). Consequently, the securities are not redeemed prior to maturity. On the final determination date, at least one underlying index closes below its respective call threshold level, but the final index value of each underlying index is greater than or equal to its respective downside threshold level. At maturity, investors will receive a cash payment equal to $1,000 per $1,000 security.

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

This scenario assumes that any underlying index closes below its respective call threshold level on each of the quarterly determination dates (beginning after one year). Consequently, the securities are not redeemed prior to maturity. On the final determination date, any underlying index closes below its respective downside threshold level. At maturity, investors will receive an amount equal to the stated principal amount multiplied by the index performance factor of the worst performing underlying index. Under these circumstances, the payment at maturity will be significantly less than the stated principal amount and could be zero.

Hypothetical Early Redemption Payment:

The hypothetical early redemption payment will be an amount in cash per stated principal amount (corresponding to a return of approximately 10.70% per annum) for each quarterly determination date (beginning after one year), as follows:

●1st determination date:

$1,107.00

●2nd determination date:

$1,133.75

●3rd determination date:

$1,160.50

●4th determination date:

$1,187.25

●5th determination date:

$1,214.00

●6th determination date:

$1,240.75

●7th determination date:

$1,267.50

●8th determination date:

$1,294.25

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

Payment at Maturity:

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

●If the final index value of each underlying index is greater than or equal to its respective call threshold level:

$1,321.00 (the actual payment at maturity for this scenario will be determined on the pricing date)

●If the final index value of any underlying index is less than its respective call threshold level but the final index value of each underlying index is greater than or equal to its respective downside threshold level:

$1,000

●If the final index value of any underlying index is less than its respective downside threshold level:

$1,000 × index performance factor of the worst performing underlying index.

Under these circumstances, you will lose a significant portion or all of your investment.

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

In the event that the early redemption date or the maturity date is postponed due to postponement of the relevant determination date, the issuer shall give notice of such postponement and, once it has been determined, of the date to which the early redemption date or the maturity date, as applicable, has been rescheduled (i) to the holder of the securities by mailing notice of such postponement by first class mail, postage prepaid, to the 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 the holder of the securities in the manner herein provided shall be conclusively presumed to have been duly given to such holder, whether or not such 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 early redemption date or the maturity date, as applicable, the business day immediately preceding the scheduled early redemption date or maturity date, as applicable, and (ii) with respect to notice of the date to which the early redemption date or the maturity date, as applicable, has been rescheduled, the business day immediately following the relevant determination date as postponed.

In the event that the securities are subject to early redemption, the issuer shall, (i) on the business day following the applicable determination date, give notice of the early redemption of the securities and the applicable early redemption payment, including specifying the payment date of the applicable amount due upon the early redemption, (x) to each registered holder of the securities by mailing notice of such early redemption by first class mail, postage

prepaid, to such registered holder's last address as it shall appear upon the registry books, (y) to the trustee by facsimile confirmed by mailing such notice to the trustee by first class mail, postage prepaid, at its New York office and (z) to the depositary by telephone or facsimile confirmed by mailing such notice to the depositary by first class mail, postage prepaid and (ii) on or prior to the early redemption date, deliver the aggregate cash amount due with respect to the securities to the trustee for delivery to the depositary, as holder of the securities.

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

Additional Information About the Securities

$1,000 / 1 security

Tax considerations:

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

Assuming this treatment of the securities is respected and subject to the discussion in "United States Federal Taxation" in the accompanying product supplement for auto-callable securities, the following U.S. federal income tax consequences should result based on current law:

￭A U.S. Holder should not be required to recognize taxable income over the term of the securities prior to settlement, other than pursuant to a sale or exchange.

￭Upon sale, exchange or settlement of the securities, a U.S. Holder should recognize gain or loss equal to the difference between the amount realized and the U.S. Holder's tax basis in the securities. Such gain or loss should be long-term capital gain or loss if the investor has held the securities for more than one year, and short-term capital gain or loss otherwise.

We do not plan to request a ruling from the Internal Revenue Service (the "IRS") regarding the treatment of the securities. An alternative characterization of the securities could materially and adversely affect the tax consequences of ownership and disposition of the securities, including the timing and character of income recognized. 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.

As discussed in the accompanying product supplement for auto-callable securities, Section 871(m) of the Internal Revenue Code of 1986, as amended, 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 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.

Both U.S. and non-U.S. investors considering an investment in the securities should

read the discussion under "Risk Factors" in this document and the discussion under "United States Federal Taxation" in the accompanying product supplement for auto-callable securities and consult their tax advisers regarding all aspects of the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments, and any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

The discussion in the preceding paragraphs under "Tax considerations" and the discussion contained in the section entitled "United States Federal Taxation" in the accompanying product supplement for auto-callable securities, insofar as they purport to describe provisions of U.S. federal income tax laws or legal conclusions with respect thereto, constitute the full opinion of Davis Polk & Wardwell LLP regarding the material U.S. federal tax consequences of an investment in the 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.

On or prior to the pricing date, we will hedge our anticipated exposure in connection with the securities by entering into hedging transactions with our affiliates and/or third-party dealers. We expect our hedging counterparties to take positions in the stocks constituting the underlying indices, in futures and/or options contracts on the underlying indices or the component stocks of the 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 index value of an underlying index, and, as a result, increase (i) the level at or above which such underlying index must close on the determination dates so that the securities are redeemed prior to maturity for the early redemption payment (depending also on the performance of the other underlying indices) and (ii) the downside threshold level for such underlying index, which is the level at or above which such underlying index must close on the final determination date so that you are not exposed to the negative performance of the worst performing underlying index at maturity (depending also on the performance of the other underlying indices). 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 determination 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 any underlying index on the determination dates, and, accordingly, whether we redeem the securities prior to maturity and the amount of cash you will receive at maturity, if any. For further information on our use of proceeds and hedging, see "Use of Proceeds and Hedging" in the accompanying product supplement.

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.
