The securities will pay no interest, do not guarantee the return of any principal at maturity and have the terms described in the accompanying product supplement, index supplement and prospectus, as supplemented or modified by this document. The securities will be automatically redeemed if the index closing value on the first determination date is greater than or equal to the initial index value, for an early redemption payment of $1,080 per security, as described below. No further payments will be made on the securities once they have been redeemed, and the investor will not participate in any appreciation of the underlying index if the securities are redeemed early. At maturity, if the securities have not previously been redeemed and the final index value is greater than or equal to the initial index value, investors will receive the greater of a (i) fixed positive return of at least 27% (to be determined on the pricing date) and (ii) a return reflecting the appreciation of the underlying index over the term of the securities. If the securities are not automatically redeemed prior to maturity and the final index value is less than the initial index value but greater than or equal to 90% of the initial index value, which we refer to as the threshold level, investors will receive the stated principal amount of their investment.

Auto-Callable Securities with Upside Participation Feature at Maturity Based on the Performance of the S&P 500® Index due September 16, 2027

Principal at Risk Securities

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 $962.00, 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 index. The estimated value of the securities is determined using our own pricing and valuation models, market inputs and assumptions relating to the underlying index, instruments based on the underlying index, 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 fixed positive return and the threshold level, 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 index, 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 index, 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.

Principal at Risk Securities

Key Investment Rationale

The securities do not provide for the regular payment of interest. Instead, the securities will be automatically redeemed for the early redemption amount if the index closing value on the first determination date is greater than or equal to the initial index value.

The following scenarios are for illustrative purposes only to demonstrate how an automatic early redemption payment or the payment at maturity (if the securities have not previously been redeemed) are calculated, and do not attempt to demonstrate every situation that may occur. Accordingly, the securities may or may not be redeemed prior to maturity and the payment at maturity may be significantly less than the stated principal amount of the securities.


Scenario 1: The securities are redeemed prior to maturity	If the underlying index closes at or above the initial index value on the first determination date, the securities will be automatically redeemed for the early redemption payment on the early redemption date. Investors do not participate in any appreciation of the underlying index.
Scenario 2: The securities are not redeemed prior to maturity, and investors receive a positive return at maturity	This scenario assumes that the underlying index closes below the initial index value on the first determination date. Consequently, the securities are not redeemed prior to maturity. On the final determination date, the underlying index closes at or above the initial index value. At maturity, investors will receive a cash payment per security equal to the greater of (i) at least $1,270 or (ii) $1,000 times the index performance factor. Under the terms of the securities, if the securities are not redeemed early, an investor would receive a payment at maturity of at least $1,270 per security if the final index value has increased by no more than at least 27% from the initial index value, and would receive $1,000 plus an amount that represents a 1-to-1 participation in the appreciation of the underlying index if the final index value has increased from the initial index value by more than at least 27%. The actual fixed positive return will be determined on the pricing date.
Scenario 3: The securities are not redeemed prior to maturity, and investors receive the stated principal amount at maturity	This scenario assumes that the underlying index closes below the initial index value on the first determination date. Consequently, the securities are not redeemed prior to maturity. On the final determination date, the underlying index closes below the initial index value but at or above the threshold level of 90% of the initial index value. At maturity, investors will receive a cash payment equal to the stated principal amount of $1,000.
Scenario 4: The securities are not redeemed prior to maturity, and investors suffer a significant loss of principal at maturity	This scenario assumes that the underlying index closes below the initial index value on the first determination date. Consequently, the securities are not redeemed prior to maturity. On the final determination date, the underlying index closes below the threshold level. At maturity, investors will receive an amount equal to the stated principal amount multiplied by the index performance factor. Under these circumstances, the securities pay significantly less than the stated principal amount by an amount proportionate to the decline in the final index value from the initial index value. You could lose up to your entire investment in the securities.

Hypothetical Examples

The following hypothetical examples are for illustrative purposes only. Whether the securities are redeemed prior to maturity will be determined by reference to the index closing value on the first determination date, and the payment at maturity will be determined by reference to the index closing value on the final determination date. The actual fixed positive return, initial index value and threshold level will be determined on the pricing date. Some numbers appearing in the examples below have been rounded for ease of analysis. All payments on the securities are subject to our credit risk. The below examples are based on the following terms:


Hypothetical Initial Index Value:	3,000
Hypothetical Threshold Level:	2,700, which is 90% of the hypothetical initial index value
Early Redemption Payment:	The early redemption payment will be an amount in cash per stated principal amount, as follows: ●1st determination date: $1,080 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 is greater than or equal to the initial index value: the greater of (i) $1,270 and (ii) $1,000 × index performance factor ●If the final index value is less than the initial index value but greater than or equal to the threshold level: $1,000 ●If the final index value is less than the threshold level: $1,000 × index performance factor In this scenario, the payment at maturity will be significantly less than the stated principal amount, and you could lose up to your entire investment in the securities.
Stated Principal Amount:	$1,000

Automatic Call:

Example 1 — The securities are redeemed following the first determination date.


Date	Index Closing Value	Payment (per Security)
1st Determination Date	3,500 (at or above the initial index value, securities are automatically redeemed)	$1,080

In this example, the index closing value on the first determination date is at or above the initial index value. Therefore, the securities are automatically redeemed on the early redemption date. Investors will receive $1,080 per security on the early redemption date. No further payments will be made on the securities once they have been redeemed, and investors do not participate in the appreciation of the underlying index.

Payment at Maturity

In the following examples, the index closing value on the first determination date is less than the initial index value, and, consequently, the securities are not automatically redeemed prior to, and remain outstanding until, maturity.

Example 1 — The final index value is at or above the initial index value.


Date	Index Closing Value	Payment (per Security)
1st Determination Date	2,650 (below the initial index value, securities are not redeemed)	--
Final Determination Date	3,900 (at or above the initial index value)	the greater of: (i) $1,270 and (ii) $1,000 × index performance factor = $1,000 × 130% = $1,300 Payment at maturity = $1,300

In this example, the index closing value is below the initial index value on the first determination date, and therefore the securities are not redeemed prior to maturity. On the final determination date, the underlying index has appreciated 30% from the hypothetical initial index value. At maturity, investors receive the greater of (i) $1,270 or (ii) $1,000 times the index performance factor. Because the underlying index has appreciated 30% from the hypothetical index value, the payment at maturity is $1,300 per security.

Example 2 — The final index value is at or above the initial index value.


Date	Index Closing Value	Payment (per Security)
1st Determination Date	2,550 (below the initial index value, securities are not redeemed)	--
Final Determination Date	3,600 (at or above the initial index value)	the greater of (i) $1,270 and (ii) $1,000 × index performance factor = $1,000 × 120% = $1,200 Payment at maturity = $1,270

In this example, the index closing value is below the initial index value on the first determination date, and therefore the securities are not redeemed prior to maturity. On the final determination date, the underlying index has appreciated 20% from the hypothetical initial index value. At maturity, investors receive the greater of (i) $1,270 or (ii) $1,000 times the index performance factor. Because the underlying index has appreciated 20% from the hypothetical index value, the payment at maturity is $1,270 per security.

Example 3 — The final index value is below the initial index value but at or above the threshold level.


Date	Index Closing Value	Payment (per Security)
1st Determination Date	2,600 (below the initial index value, securities are not redeemed)	--
Final Determination Date	2,800 (below the initial index value, but above the threshold level)	$1,000

Principal at Risk Securities

In this example, the index closing value is below the initial index value on the first determination date, and therefore the securities are not redeemed prior to maturity. On the final determination date, the final index value is below the initial index value but at or above the threshold level, and accordingly, investors receive a payment at maturity equal to the stated principal amount of $1,000 per security.

Example 4 — The final index value is below the threshold level.


Date	Index Closing Value	Payment (per Security)
1st Determination Date	2,600 (below the initial index value, securities are not redeemed)	--
Final Determination Date	1,500 (below the threshold level)	$1,000 × index performance factor = $1,000 × 50% = $500

In this example, the index closing value is below the initial index value on the first determination date, and therefore the securities are not redeemed prior to maturity. Because the final index value is less than the threshold level, investors lose a significant portion of their investment in an amount proportionate to the decline in the final index value from the initial index value. The payment at maturity is $500 per security, representing a loss of 50% of the stated principal amount.

If the securities are not redeemed prior to maturity and the final index value is less than the threshold level, you will lose a significant portion or all of your investment in the securities.

Risk Factors

This section describes the material risks relating to the securities. For further discussion of these and other risks, you should read the section entitled “Risk Factors” in the accompanying product supplement, index supplement and prospectus. We also urge you to consult with your investment, legal, tax, accounting and other advisers in connection with your investment in the securities.

Risks Relating to an Investment in the Securities

￭The securities do not pay interest or guarantee the return of any principal. The terms of the securities differ from those of ordinary debt securities in that they do not pay interest or guarantee the return of any of the principal amount at maturity. If the securities have not been automatically redeemed prior to maturity and the final index value is less than the threshold level, you will be exposed to the full percentage decline in the value of the underlying index over the term of the securities. In this case, the payment at maturity will be less than 90% of the stated principal amount and could be zero.

￭If the securities are automatically redeemed, the appreciation potential of the securities is limited by the fixed early redemption payment specified for the first determination date. If the securities are automatically redeemed following the first determination date, the appreciation potential of the securities is limited to the fixed early redemption payment specified for the first determination date. No further payments will be made on the securities once they have been redeemed, and you will not participate in any appreciation of the underlying index if the securities are redeemed early.

￭The market price will be influenced by many unpredictable factors. Several factors, many of which are beyond our control, will influence the value of the securities in the secondary market and the price at which MS & Co. may be willing to purchase or sell the securities in the secondary market. We expect that generally the level of interest rates available in the market and the value of the underlying index on any day will affect the value of the securities more than any other factors. Other factors that may influence the value of the securities include:

othe volatility (frequency and magnitude of changes in value) of the underlying index,

ogeopolitical conditions and economic, financial, political, regulatory or judicial events that affect the component stocks of the underlying index or securities markets generally and which may affect the value of the underlying index,

odividend rates on the securities underlying the underlying index,

othe time remaining until the securities mature,

ointerest and yield rates in the market,

othe availability of comparable instruments,

othe composition of the underlying index and changes in the constituent stocks of such index, and

oany actual or anticipated changes in our credit ratings or credit spreads.

Generally, the longer the time remaining to maturity, the more the market price of the securities will be affected by the other factors described above. Some or all of these factors will influence the price that you will receive if you sell your securities prior to maturity. You cannot predict the future performance of the underlying index based on its historical performance. There can be no assurance that the closing value of the underlying index will be at or above the initial index value on the first determination date or at or above the threshold level on the final determination date so that you do not suffer a significant loss on your initial investment in the securities. See “S&P 500® Index Overview” below.

￭The securities are subject to our credit risk, and any actual or anticipated changes to our credit ratings or credit spreads may adversely affect the market value of the securities. You are dependent on our ability to pay all amounts due on the securities upon an early redemption or at maturity and therefore you are subject to our credit risk. If we default on our obligations under the securities, your investment would be at risk and you could lose some or all of

September 2024 Page 8

Morgan Stanley Finance LLC

Auto-Callable Securities with Upside Participation Feature at Maturity Based on the Performance of the S&P 500® Index due September 16, 2027

Principal at Risk Securities

your investment. As a result, the market value of the securities prior to maturity will be affected by changes in the market’s view of our creditworthiness. Any actual or anticipated decline in our credit ratings or increase in the credit spreads charged by the market for taking our credit risk is likely to adversely affect the market value of the securities.

￭As a finance subsidiary, MSFL has no independent operations and will have no independent assets. As a finance subsidiary, MSFL has no independent operations beyond the issuance and administration of its securities and will have no independent assets available for distributions to holders of MSFL securities if they make claims in respect of such securities in a bankruptcy, resolution or similar proceeding. Accordingly, any recoveries by such holders will be limited to those available under the related guarantee by Morgan Stanley and that guarantee will rank pari passu with all other unsecured, unsubordinated obligations of Morgan Stanley. Holders will have recourse only to a single claim against Morgan Stanley and its assets under the guarantee. Holders of securities issued by MSFL should accordingly assume that in any such proceedings they would not have any priority over and should be treated pari passu with the claims of other unsecured, unsubordinated creditors of Morgan Stanley, including holders of Morgan Stanley-issued securities.

￭Reinvestment risk. The term of your investment in the securities may be shortened due to the automatic early redemption feature of the securities. If the securities are redeemed prior to maturity, you will receive no further payments on the securities and may be forced to invest in a lower interest rate environment and may not be able to reinvest at comparable terms or returns. However, under no circumstances will the securities be redeemed at any point other than the specified early redemption date.

￭The securities will not be listed on any securities exchange and secondary trading may be limited, and accordingly, you should be willing to hold your securities for the entire 3-year term of the securities. The securities will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the securities. 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. When it does make a market, it will generally do so for transactions of routine secondary market size at prices based on its estimate of the current value of the securities, taking into account its bid/offer spread, our credit spreads, market volatility, the notional size of the proposed sale, the cost of unwinding any related hedging positions, the time remaining to maturity and the likelihood that it will be able to resell the securities. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the securities easily. Since other broker-dealers may not participate significantly in the secondary market for the securities, the price at which you may be able to trade your securities is likely to depend on the price, if any, at which MS & Co. is willing to transact. If, at any time, MS & Co. were to cease making a market in the securities, it is likely that there would be no secondary market for the securities. Accordingly, you should be willing to hold your securities to maturity.

￭Not equivalent to investing in the underlying index. Investing in the securities is not equivalent to investing in the underlying index or its component stocks. Investors in the securities will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to stocks that constitute the underlying index.

￭The rate we are willing to pay for securities of this type, maturity and issuance size is likely to be lower than the rate implied by our secondary market credit spreads and advantageous to us. Both the lower rate and the inclusion of costs associated with issuing, selling, structuring and hedging the securities in the original issue price reduce the economic terms of the securities, cause the estimated value of the securities to be less than the original issue price and will adversely affect secondary market prices. Assuming no change in market conditions or any other relevant factors, the prices, if any, at which dealers, including MS & Co., may be willing to purchase the securities in secondary market transactions will likely be significantly lower than the original issue price, because secondary market prices will exclude the issuing, selling, structuring and hedging-related costs that are included in the original issue price and borne by you and because the secondary market prices will reflect our secondary market credit spreads and the bid-offer spread that any dealer would charge in a secondary market transaction of this type as well as other factors.

The inclusion of the costs of issuing, selling, structuring and hedging the securities in the original issue price and the lower rate we are willing to pay as issuer make the economic terms of the securities less favorable to you than they otherwise would be.

Principal at Risk Securities

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 index, and to our secondary market credit spreads, it would do so based on values higher than the estimated value, and we expect that those higher values will also be reflected in your brokerage account statements.

￭The estimated value of the securities is determined by reference to our pricing and valuation models, which may differ from those of other dealers and is not a maximum or minimum secondary market price. These pricing and valuation models are proprietary and rely in part on subjective views of certain market inputs and certain assumptions about future events, which may prove to be incorrect. As a result, because there is no market-standard way to value these types of securities, our models may yield a higher estimated value of the securities than those generated by others, including other dealers in the market, if they attempted to value the securities. In addition, the estimated value on the pricing date does not represent a minimum or maximum price at which dealers, including MS & Co., would be willing to purchase your securities in the secondary market (if any exists) at any time. The value of your securities at any time after the date of this document will vary based on many factors that cannot be predicted with accuracy, including our creditworthiness and changes in market conditions. See also “The market price will be influenced by many unpredictable factors” above.

￭Hedging and trading activity by our affiliates could potentially affect the value of the securities. One or more of our affiliates and/or third-party dealers expect to carry out hedging activities related to the securities (and to other instruments linked to the underlying index or its component stocks), including trading in the stocks that constitute the underlying index as well as in other instruments related to the underlying index. As a result, 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. Some of our affiliates also trade the stocks that constitute the underlying index and other financial instruments related to the underlying index on a regular basis as part of their general broker-dealer and other businesses. Any of these hedging or trading activities on or prior to the pricing date could potentially increase the initial index value, and, therefore, could increase (i) the value at or above which the underlying index must close on the determination dates so that the securities are redeemed prior to maturity for the early redemption payment, or so that you receive a positive return at maturity, and (ii) the threshold level, which is the value at or above which the underlying index must close on the final determination date so that you are not exposed to the negative performance of the underlying index at maturity. Additionally, such hedging or trading activities during the term of the securities could potentially affect the value of the 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.

￭The calculation agent, which is a subsidiary of Morgan Stanley and an affiliate of MSFL, will make determinations with respect to the securities. As calculation agent, MS & Co. will determine the initial index value, the threshold level, whether the securities will be redeemed on the early redemption date, the final index value and the payment you will receive at maturity, if any. Moreover, certain determinations made by MS & Co., in its capacity as calculation agent, may require it to exercise discretion and make subjective judgments, such as with respect to the occurrence or non-occurrence of market disruption events and the selection of a successor index or calculation of the index closing value in the event of a market disruption event or discontinuance of the underlying index, may adversely affect the payout to you at maturity, if any. For further information regarding these types of determinations, see "Description of Auto-Callable Securities—Postponement of Determination Dates," "—Alternate Exchange Calculation in Case of an Event of Default,” "—Discontinuance of Any Underlying Index; Alteration of Method of Calculation” and "—Calculation Agent and Calculations" in the accompanying product supplement. In addition, MS & Co. has determined the estimated value of the securities on the pricing date.

￭The U.S. federal income tax consequences of an investment in the securities are uncertain. Please read the discussion under “Additional Information – Tax considerations” in this document and the discussion under “United States Federal Taxation” in the accompanying product supplement for auto-callable securities (together, the “Tax Disclosure Sections”) concerning the U.S. federal income tax consequences of an investment in the securities. There is no direct legal authority regarding the proper U.S. federal tax treatment of the securities, and we do not plan to request

a ruling from the Internal Revenue Service (the “IRS”). Consequently, significant aspects of the tax treatment of the securities are uncertain, and the IRS or a court might not agree with the tax treatment of a security as a single financial contract that is an “open transaction” for U.S. federal income tax purposes. If the IRS were successful in asserting an alternative treatment of the securities, the tax consequences of the ownership and disposition of the securities, including the timing and character of income recognized by U.S. Holders and the withholding tax consequences to Non-U.S. Holders, might be materially and adversely affected. Moreover, future legislation, Treasury regulations or IRS guidance could adversely affect the U.S. federal tax treatment of the securities, possibly retroactively.

Both U.S. and Non-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, as well as any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Risks Relating to the Underlying Index

￭Adjustments to the underlying index could adversely affect the value of the securities. The publisher of the underlying index may add, delete or substitute the component stocks of the underlying index or make other methodological changes that could change the value of the underlying index. Any of these actions could adversely affect the value of the securities. The publisher of the underlying index may also discontinue or suspend calculation or publication of the underlying index at any time. In these circumstances, MS & Co., as the calculation agent, will have the sole discretion to substitute a successor index that is comparable to the discontinued index. MS & Co. could have an economic interest that is different than that of investors in the securities insofar as, for example, MS & Co. is permitted to consider indices that are calculated and published by MS & Co. or any of its affiliates. If MS & Co. determines that there is no appropriate successor index, the determination of whether the securities will be redeemed on the early redemption date or the payment at maturity, as applicable, will be based on whether the value of the underlying index based on the closing prices of the securities constituting the underlying index at the time of such discontinuance, without rebalancing or substitution, computed by MS & Co. as calculation agent in accordance with the formula for calculating the underlying index last in effect prior to such discontinuance is greater than or equal to the initial index value or threshold level, as applicable.

S&P 500® Index Overview

The S&P 500® Index, which is calculated, maintained and published by S&P® Dow Jones Indices LLC (“S&P®”), is intended to provide a benchmark for performance measurement of the large capitalization segment of the U.S. equity markets by tracking the stock price movement of 500 companies with large market capitalizations. Component stocks of the S&P 500® Index are required to have a total company level market capitalization that reflects approximately the 85th percentile of the S&P® Total Market Index. The S&P 500® Index measures the relative performance of the common stocks of 500 companies as of a particular time as compared to the performance of the common stocks of 500 similar companies during the base period of the years 1941 through 1943. For additional information about the S&P 500® Index, see the information set forth under “S&P® U.S. Indices—S&P 500® Index” in the accompanying index supplement.

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 determination date as postponed.

Additional Information About the Securities


Additional Information:
Minimum ticketing size:	$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 3 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 stocks of the underlying index, futures and/or options contracts on the underlying index or its component stocks listed on major securities markets, or positions in any other available securities or instruments that they may wish to use in connection with such hedging. Such purchase activity could potentially increase the initial index value, and, therefore, could increase (i) the value at or above which the underlying index must close on the determination dates so that the securities are redeemed prior to maturity for the early redemption payment, or so that you receive a positive return at maturity, and (ii) the threshold level, which is the value at or above which the underlying index must close on the final determination date so that you are not exposed to the negative performance of the underlying index at maturity. In addition, through our affiliates, we are likely to modify our hedge position throughout the term of the securities, including on the final determination date, by purchasing and selling the stocks constituting the underlying index, futures or options contracts on the underlying index or its component stocks listed on major securities markets or positions in any other available securities or instruments that we may wish to use in connection with such hedging activities. As a result, 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. We cannot give any assurance that our hedging activities will not affect the value of the underlying index, and, therefore, adversely affect the value of the securities or the payment you will receive at maturity. 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.
Supplemental information regarding plan of distribution; conflicts of interest:	Selected dealers, which may include our affiliates, and their financial advisors will collectively receive from the agent a fixed sales commission of $ for each security they sell. 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 fixed positive return, such that for each security the estimated value on the pricing date will be no lower than the minimum level described in “Investment Summary” beginning on page 2. 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. See “Plan of Distribution (Conflicts of Interest)” and “Use of
