The notes are unsecured obligations of Morgan Stanley Finance LLC (“MSFL”) and are fully and unconditionally guaranteed by Morgan Stanley. The notes will pay no interest and will have the terms described in the accompanying product supplement, index supplement and prospectus, as supplemented and modified by this document. If the underlying index appreciates or does not depreciate at all over the term of the notes, you will receive the stated principal amount for each note you hold at maturity plus the upside payment of at least $73 (to be determined on the pricing date). If the underlying index depreciates over the term of the notes, we will pay per note a payment at maturity of only $1,000, without any positive return on the notes. The notes are for investors who are concerned about principal risk but seek an equity index-based return, and who are willing to forgo current income and returns above the fixed upside payment in exchange for the repayment of principal at maturity plus the possibility of receiving a return of at least 7.30% (to be determined on the pricing date) if the final index value is greater than or equal to the initial index value.

Investment Summary

Market-Linked Notes

The Market-Linked Notes due November 12, 2024 Based on the Value of the NASDAQ-100 Index® (the “notes”) provide the possibility of receiving a fixed return of at least 7.30% (to be determined on the pricing date) if the final index value is greater than or equal to the initial index value. The notes provide investors:

￭the repayment of principal at maturity, subject to our creditworthiness

￭the opportunity to receive a fixed return of at least 7.30% (to be determined on the pricing date) if the underlying index has appreciated or has not depreciated at all over the term of the notes.

￭no exposure to any decline of the underlying index if the notes are held to maturity

At maturity, if the underlying index has depreciated, you will receive the stated principal amount of $1,000 per note, without any positive return on your investment. All payments on the notes, including the repayment of principal at maturity, are subject to our credit risk.

Maturity:	13 months
Upside payment:	At least $73 per note (7.30% of the stated principal amount). The actual upside payment will be determined on the pricing date.
Interest:	None

The original issue price of each note is $1,000. This price includes costs associated with issuing, selling, structuring and hedging the notes, which are borne by you, and, consequently, the estimated value of the notes on the pricing date will be less than $1,000. We estimate that the value of each note on the pricing date will be approximately $977.40, or within $35.00 of that estimate. Our estimate of the value of the notes 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 notes on the pricing date, we take into account that the notes comprise both a debt component and a performance-based component linked to the underlying index. The estimated value of the notes 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 notes?

In determining the economic terms of the notes, including the upside payment, 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 notes 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 notes?

The price at which MS & Co. purchases the notes 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 notes 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 notes 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 notes, and, if it once chooses to make a market, may cease doing so at any time.

Key Investment Rationale

The Market-Linked Notes offer investors the opportunity to receive a fixed positive return of at least 7.30% (to be determined on the pricing date) if the underlying index appreciates or does not depreciate at all over the term of the notes and provide for the repayment of principal at maturity. They are for investors who are concerned about principal risk but seek an equity index-based return, and who are willing to forgo yield in exchange for the repayment of principal at maturity plus the possibility of receiving a return of at least 7.30% (to be determined on the pricing date) if the final index value is greater than or equal to the initial index value.

Repayment of Principal	The notes offer investors the possibility of receiving a fixed positive return of at least 7.30% (to be determined on the pricing date) if the underlying index appreciates or does not depreciate at all over the term of the notes, while providing for the repayment of principal in full at maturity.
Upside Scenario	The underlying index increases in value or does not depreciate at all, and, at maturity, the investor receives the stated principal amount of $1,000 plus the upside payment of at least $73 (7.30% of the stated principal amount). The actual upside payment will be determined on the pricing date.
Par Scenario	The underlying index declines, and, at maturity, the notes pay only the stated principal amount of $1,000.

Hypothetical Payout on the Notes

At maturity, if the final index value is greater than or equal to the initial index value, we will pay per note the stated principal amount of $1,000 plus the upside payment of at least $73 (7.30% of the stated principal amount). The actual upside payment will be determined on the pricing date. If the final index value is less than the initial index value, we will pay per note a payment at maturity of only $1,000.

The table below illustrates the payment at maturity for each note for a hypothetical range of index percent change and does not cover the complete range of possible payouts at maturity. The table assumes a hypothetical initial index value of 12,000.00 and a hypothetical upside payment of $73 per note (7.30% of the stated principal amount). The actual initial index value and upside payment will be determined on the pricing date.

Risk Factors

This section describes the material risks relating to the notes. 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 your investment, legal, tax, accounting and other advisers in connection with your investment in the notes.

Risks Relating to an Investment in the Notes

￭The notes do not pay interest and may not pay more than the stated principal amount at maturity. If final index value is less than the initial index value, you will receive only the stated principal amount of $1,000 for each note you hold at maturity. As the notes do not pay any interest, the overall return on the notes (the effective yield to maturity) may be less than the amount that would be paid on a conventional debt security of ours of comparable maturity. The notes have been designed for investors who are willing to forgo market floating interest rates in exchange for the repayment of principal at maturity plus the possibility of receiving a return of at least 7.30% (to be determined on the pricing date) if the final index value is greater than or equal to the initial index value.

￭The appreciation potential is fixed and limited. Where the final index value is greater than or equal to the initial index value, the appreciation potential of the notes is limited to the upside payment of at least $73 per note (7.30% of the stated principal amount, to be determined on the pricing date), even if the final index value is significantly greater than the initial index value.

￭The market price of the notes will be influenced by many unpredictable factors. Several factors will influence the value of the notes in the secondary market and the price at which MS & Co. may be willing to purchase or sell the notes in the secondary market, including the value of the underlying index at any time and, in particular, on the determination date, the volatility (frequency and magnitude of changes in value) of the underlying index, dividend rate on the stocks underlying the index, interest and yield rates in the market, time remaining until the notes mature, geopolitical conditions and economic, financial, political, regulatory or judicial events that affect the underlying index or equities markets generally and which may affect the final index value of the underlying index and any 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 notes will be affected by the other factors described above. The value of the underlying index may be, and has recently been, volatile, and we can give you no assurance that the volatility will lessen. See “NASDAQ-100 Index® Overview” below. You may receive less, and possibly significantly less, than the stated principal amount per note if you try to sell your notes prior to maturity.

￭The notes 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 notes. You are dependent on our ability to pay all amounts due on the notes at maturity and therefore you are subject to our credit risk. The notes are not guaranteed by any other entity. If we default on our obligations under the notes, your investment would be at risk and you could lose some or all of your investment. As a result, the market value of the notes 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 notes.

￭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.

￭The amount payable on the notes is not linked to the value of the underlying index at any time other than the determination date. The final index value will be based on the index closing value on the determination date, subject to postponement for non-index business days and certain market disruption events. Even if the value of the underlying index appreciates prior to the determination date but then drops by the determination date, the payment at maturity may be less, and may be significantly less, than it would have been had the payment at maturity been linked to the value of the underlying index prior to such drop. Although the actual value of the underlying index on the stated maturity date or at other times during the term of the notes may be higher than the index closing value on the determination date, the payment at maturity will be based solely on the index closing value on the determination date.

Market-Linked Notes due November 12, 2024

Based on the Value of the NASDAQ-100 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 notes in the original issue price reduce the economic terms of the notes, cause the estimated value of the notes 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 notes 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 notes in the original issue price and the lower rate we are willing to pay as issuer make the economic terms of the notes less favorable to you than they otherwise would be.

However, because the costs associated with issuing, selling, structuring and hedging the notes 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 notes 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 notes 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 notes than those generated by others, including other dealers in the market, if they attempted to value the notes. 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 notes in the secondary market (if any exists) at any time. The value of your notes 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 of the notes will be influenced by many unpredictable factors” above.

￭Investing in the notes is not equivalent to investing in the underlying index. Investing in the notes is not equivalent to investing in the underlying index or its component stocks. As an investor in the notes, you 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. See “Hypothetical Payout on the Notes” above.

￭The notes will not be listed on any securities exchange and secondary trading may be limited. The notes will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the notes. MS & Co. may, but is not obligated to, make a market in the notes 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 notes, 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 notes. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the notes easily. Since other broker-dealers may not participate significantly in the secondary market for the notes, the price at which you may be able to trade your notes 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 notes, it is likely that there would be no secondary market for the notes. Accordingly, you should be willing to hold your notes to maturity.

￭The calculation agent, which is a subsidiary of Morgan Stanley and an affiliate of MSFL, will make determinations with respect to the notes. As calculation agent, MS & Co. will determine the initial index value and the final index value, and will calculate the amount of cash you will receive at maturity. 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 discontinuance of the underlying index. These potentially subjective determinations may adversely affect the payout to you at maturity. For further information regarding these types of determinations, see “Description of Equity-Linked Notes—Calculation Agent and Calculations,” “—Alternate Exchange Calculation in the Case of an Event of Default” and “—Discontinuance of Any Underlying Index; Alteration of Method of Calculation” in the accompanying product supplement for equity-linked notes. In addition, MS & Co. has determined the estimated value of the notes on the pricing date.

￭Hedging and trading activity by our affiliates could potentially adversely affect the value of the notes. One or more of our affiliates and/or third-party dealers expect to carry out hedging activities related to the notes (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

October 2023Page 6

Morgan Stanley Finance LLC

Market-Linked Notes due November 12, 2024

Based on the Value of the NASDAQ-100 Index®

￭other instruments related to the underlying index. As a result, these entities may be unwinding or adjusting hedge positions during the term of the notes, and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the 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 the value at or above which the underlying index must close on the determination date before you would receive at maturity a payment that exceeds the stated principal amount of the notes. Additionally, such hedging or trading activities during the term of the notes, including on the determination date, could adversely affect the closing value of the underlying index on the determination date, and, accordingly, the amount of cash an investor will receive at maturity.

Risks Relating to the Underlying Index

￭Adjustments to the underlying index could adversely affect the value of the notes. The publisher of the underlying index can add, delete or substitute the stocks underlying the index, and can make other methodological changes required by certain events relating to the underlying stocks, such as stock dividends, stock splits, spin-offs, rights offerings and extraordinary dividends, that could change the value of the underlying index. Any of these actions could adversely affect the value of the notes. 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 notes 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 on such determination date, the index closing value on the determination date will be an amount based on the values of the stocks underlying the discontinued 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 index closing value last in effect prior to discontinuance of the underlying index.

Additional Information About the Notes

Additional Information:
Minimum ticketing size:	$1,000 / 1 note
Tax considerations	There is uncertainty regarding the U.S. federal income tax consequences of an investment in the notes due to the lack of governing authority. We intend to treat the notes as “contingent payment debt instruments” for U.S. federal income tax purposes, as described in the section of the accompanying product supplement called “United States Federal Taxation—Tax Consequences to U.S. Holders” (“CPDIs”). In the opinion of our counsel, Davis Polk & Wardwell LLP, based on current market conditions and based on certain representations made by us, this treatment of the notes is reasonable under current law. Except where stated otherwise, the following discussion is based on the treatment of the notes as “CPDIs.” If you are a U.S. taxable investor, you generally will be subject to annual income tax based on the “comparable yield” (as defined in the accompanying product supplement) of the notes, adjusted upward or downward to reflect the difference, if any, between the actual and projected amount of the payments on the notes. The comparable yield will be determined on the pricing date and may be significantly higher or lower than the comparable yield if the notes were priced on the date hereof. The comparable yield and the projected payment schedule (or information about how to obtain them) will be provided in the final pricing supplement. In addition, any gain recognized by U.S. taxable investors on the sale or exchange, or at maturity, of the notes generally will be treated as ordinary income. You should read the discussion under “United States Federal Taxation” in the accompanying product supplement concerning the U.S. federal income tax consequences of an investment in the notes. The comparable yield and the projected payment schedule will not be provided for any purpose other than the determination of U.S. Holders’ accruals of interest income and adjustments thereto in respect of the notes for U.S. federal income tax purposes, and we make no representation regarding the actual amount of the payments that will be made on the notes. Possible Alternative Tax Treatment of an Investment in the Notes If market conditions change prior to the notes' issuance or if the IRS disagrees with our determination, alternative tax treatments are possible. In particular, there is a risk (which, depending on the likelihood that the maximum amount would be paid, could be substantial) that the notes could be treated as original issue discount debt instruments (that are not CPDIs) with an amount of original issue discount equal to the upside payment. Under this treatment, if you are a U.S. Holder, your annual taxable income from (and adjusted tax basis in) the notes could be greater than if it were based on the comparable yield, and any loss recognized upon a disposition of the notes (including upon maturity) would be capital loss, the deductibility of which is subject to limitations. Accordingly, this alternative treatment could result in adverse tax consequences to you. If you are a non-U.S. investor, please also read the section of the accompanying product supplement called “United States Federal Taxation—Tax Consequences to Non-U.S. Holders.” As discussed in the accompanying product supplement, Section 871(m) of the Internal Revenue Code of 1986, as amended (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 Internal Revenue Service (“IRS”) notice, Section 871(m) will not apply to securities issued before January 1, 2025 that do not have a delta of one with respect to any Underlying Security. Based on the terms of the notes and current market conditions, we expect that the notes will not have a delta of one with respect to any Underlying Security on the pricing date. However, we will provide an updated determination in the final pricing supplement. Assuming that the notes do not have a delta of one with respect to any Underlying Security, our counsel is of the opinion that the notes 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 notes. You should consult your tax adviser regarding all aspects of the U.S. federal income tax consequences of an investment in the notes, including possible alternative treatments, as well as 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, 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 notes.
Use of proceeds and hedging:	The proceeds from the sale of the notes will be used by us for general corporate purposes. We will receive, in aggregate, $1,000 per note issued, because, when we enter into hedging transactions in order to meet our obligations under the notes, our hedging counterparty will reimburse the cost of the agent’s commissions. The costs of the notes borne by you and described beginning on page 2 above comprise the agent’s commissions

	and the cost of issuing, structuring and hedging the notes. On or prior to the pricing date, we will hedge our anticipated exposure in connection with the notes 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 options contracts on the underlying index and any component stocks of the underlying index listed on major securities markets or positions in any other available securities or instruments that they may wish to use in connection with such hedging. Such purchase activity could potentially increase the value of the underlying index on the pricing date, and, therefore, could increase the value at or above which the underlying index must close on the determination date before you would receive at maturity a payment that exceeds the stated principal amount of the notes. In addition, through our affiliates, we are likely to modify our hedge position throughout the term of the notes, including on the 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 notes, and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the 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 notes 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 notes, either directly or indirectly.
Supplemental information regarding plan of distribution; conflicts of interest:	MS & Co. expects to sell all of the notes that it purchases from us to an unaffiliated dealer at a price of $ per note, for further sale to certain fee-based advisory accounts at the price to public of $1,000 per note. MS & Co. will not receive a sales commission with respect to the notes. 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 notes. When MS & Co. prices this offering of notes, it will determine the economic terms of the notes, including the upside payment, such that for each note 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 Proceeds and Hedging” in the accompanying product supplement.
