Trigger Performance Leveraged Upside SecuritiesSM

Fully and Unconditionally Guaranteed by Morgan Stanley

Principal at Risk Securities

The Trigger PLUS are unsecured obligations of Morgan StanleyFinance LLC (“MSFL”) and are fully and unconditionally guaranteed by Morgan Stanley. The Trigger PLUS will pay no interest, do not guarantee any return of principal at maturity and have the terms described in the accompanying product supplement for PLUS, index supplement and prospectus, as supplemented or modified by this document. At maturity, if the shares of the SPDR® S&P 500® ETF Trust, which we refer to as the underlying shares, have appreciated in value, investors will receive the stated principal amount of their investment plus leveraged upside performance of the underlying shares. If the underlying shares have remained unchanged or depreciated in value but the final share price is greater than or equal to the trigger level, investors will receive the stated principal amount of their investment. However, if the underlying shares have depreciated in value so that the final share price is less than the trigger level, investors will lose a significant portion or all of their investment, resulting in a 1% loss for every 1% decline in the share price over the term of the Trigger PLUS. Under these circumstances, the payment at maturity will be less than 80% of the stated principal amount and could be zero. Accordingly, you may lose your entire investment. These long-dated Trigger PLUS are for investors who seek a return based on the performance of the underlying shares and who are willing to risk their principal and forgo current income in exchange for the leverage feature and the limited protection against loss that applies only if the final share price is greater than or equal to the trigger level. Investors may lose their entire initial investment in the Trigger PLUS. The Trigger PLUS are notes issued as part of MSFL’s Series A Global Medium-Term Notes program.

All payments are subject to our credit risk. If we default on our obligations, you could lose some or all of your investment. These Trigger PLUS are not secured obligations and you will not have any security interest in, or otherwise have any access to, any underlying reference asset or assets.

Investment Summary

Trigger Performance Leveraged Upside Securities

Principal at Risk Securities

The Trigger PLUS Based on the Performance of the SPDR® S&P 500® ETF Trust due December 20, 2028 (the “Trigger PLUS”) can be used:

￭As an alternative to direct exposure to the underlying shares that enhances returns for any positive performance of the underlying shares.

￭To potentially outperform the underlying shares in a bullish scenario.

￭To achieve similar levels of upside exposure to the underlying shares as a direct investment while using fewer dollars by taking advantage of the leverage factor.

￭To provide limited protection against a loss of principal in the event of a decline of the underlying shares as of the valuation date, but only if the final share price is greater than or equal to the trigger level.

Maturity:	5 years
Leverage factor:	132.50% (applicable only if the final share price is greater than the initial share price)
Minimum payment at maturity:	None. Investors may lose their entire initial investment in the Trigger PLUS.
Trigger level:	80% of the initial share price
Interest:	None
Listing:	The Trigger PLUS will not be listed on any securities exchange

The original issue price of each Trigger PLUS is $1,000. This price includes costs associated with issuing, selling, structuring and hedging the Trigger PLUS, which are borne by you, and, consequently, the estimated value of the Trigger PLUS on the pricing date is less than $1,000. We estimate that the value of each Trigger PLUS on the pricing date is $985.60.

What goes into the estimated value on the pricing date?

In valuing the Trigger PLUS on the pricing date, we take into account that the Trigger PLUS comprise both a debt component and a performance-based component linked to the underlying shares. The estimated value of the Trigger PLUS is determined using our own pricing and valuation models, market inputs and assumptions relating to the underlying shares, instruments based on the underlying shares, 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 Trigger PLUS?

In determining the economic terms of the Trigger PLUS, including the leverage factor and the trigger 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 Trigger PLUS 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 Trigger PLUS?

The price at which MS & Co. purchases the Trigger PLUS in the secondary market, absent changes in market conditions, including those related to the underlying shares, 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 Trigger PLUS 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 Trigger PLUS in the secondary market, absent changes in market conditions,

including those related to the underlying shares, 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 Trigger PLUS, and, if it once chooses to make a market, may cease doing so at any time.

Key Investment Rationale

The Trigger PLUS offer leveraged exposure to any positive performance of the underlying shares. In exchange for the leverage feature, investors are exposed to the risk of loss of a significant portion or all of their investment due to the trigger feature. At maturity, if the shares of the Fund, which we refer to as the underlying shares, have appreciated in value, investors will receive the stated principal amount of their investment plus leveraged upside performance of the underlying shares. If the underlying shares have depreciated in value but the final share price is greater than or equal to the trigger level, investors will receive the stated principal amount of their investment. However, if the underlying shares have depreciated in value so that the final share price is less than the trigger level, investors will lose a significant portion or all of their investment, resulting in a 1% loss for every 1% decline in the share price over the term of the Trigger PLUS. Under these circumstances, the payment at maturity will be less than 80% of the stated principal amount and could be zero. Investors may lose their entire initial investment in the Trigger PLUS. All payments on the Trigger PLUS are subject to our credit risk.

Leveraged Upside Performance	The Trigger PLUS offer investors an opportunity to capture enhanced returns relative to a direct investment in the underlying shares.
Trigger Feature	At maturity, even if the underlying shares have declined over the term of the Trigger PLUS, you will receive your stated principal amount, but only if the final share price is greater than or equal to the trigger level.
Upside Scenario	The final share price is greater than the initial share price, and, at maturity, you receive a full return of principal as well as 132.50% of the increase in the value of the underlying shares.
Par Scenario	The final share price is less than or equal to the initial share price but is greater than or equal to the trigger level. In this case, you receive the stated principal amount of $1,000 at maturity even though the underlying shares have depreciated.
Downside Scenario	The final share price is less than the trigger level. In this case, the Trigger PLUS redeem for at least 20% less than the stated principal amount, and this decrease will be by an amount proportionate to the decline in the value of the underlying shares over the term of the Trigger PLUS. Under these circumstances, the payment at maturity will be less than 80% of the stated principal amount. For example, if the final share price is 90% less than the initial share price, the Trigger PLUS will be redeemed at maturity for a loss of 90% of principal at $100, or 10% of the stated principal amount. There is no minimum payment at maturity on the Trigger PLUS, and you could lose your entire investment.

How it works

￭Upside Scenario. If the final share price is greater than the initial share price, the investor would receive the $1,000 stated principal amount plus 132.50% of the appreciation of the underlying shares over the term of the Trigger PLUS.

￭If the underlying shares appreciate 5%, the investor would receive a 6.625‬% return, or $1,066.25‬ per Trigger PLUS.

￭Par Scenario. If the final share price is less than or equal to the initial share price and is greater than or equal to the trigger level of 80% of the initial share price, the investor would receive $1,000 stated principal amount.

￭If the underlying shares depreciate 10%, investors would receive the $1,000 stated principal amount.

￭Downside Scenario. If the final share price is less than the trigger level of 80% of the initial share price, the investor would receive an amount that is significantly less than the $1,000 stated principal amount, based on a 1% loss of principal for each 1% decline in the underlying shares. Under these circumstances, the payment at maturity will be less than 80% of the stated principal amount per Trigger PLUS. There is no minimum payment at maturity on the Trigger PLUS.

￭If the underlying shares depreciate 90%, the investor would lose 90% of the investor’s principal and receive only $100 per Trigger PLUS at maturity, or 10% of the stated principal amount.

Risk Factors

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

Risks Relating to an Investment in the Trigger PLUS

￭The Trigger PLUS do not pay interest or guarantee return of any principal.The terms of the Trigger PLUS differ from those of ordinary debt securities in that the Trigger PLUS do not pay interest or guarantee payment of any principal at maturity. If the final share price is less than the trigger level (which is 80% of the initial share price), the payout at maturity will be an amount in cash that is at least 20% less than the $1,000 stated principal amount of each Trigger PLUS, and this decrease will be by an amount proportionate to the full decrease in the price of the underlying shares over the term of the Trigger PLUS, without any buffer. There is no minimum payment at maturity on the Trigger PLUS, and, accordingly, you could lose your entire initial investment in the Trigger PLUS.

￭The market price of the Trigger PLUS will be influenced by many unpredictable factors. Several factors, many of which are beyond our control, will influence the value of the Trigger PLUS in the secondary market and the price at which MS & Co. may be willing to purchase or sell the Trigger PLUS in the secondary market, including the trading price (including whether the trading price is at or below the trigger level), volatility (frequency and magnitude of changes in value) and dividends of the underlying shares and of the stocks composing the S&P 500® Index (“the share underlying index”), interest and yield rates in the market, time remaining until the Trigger PLUS mature,geopolitical conditions and economic, financial, political and regulatory or judicial events that affect the underlying shares or equities markets generally and which may affect the final share price of the underlying shares, the occurrence of certain events affecting the underlying shares that may or may not require an adjustment to the adjustment factor, 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 Trigger PLUS will be affected by the other factors described above. The price of the underlying shares may be, and has recently been, volatile, and we can give you no assurance that the volatility will lessen. See “SPDR® S&P 500® ETF Trust” below. You may receive less, and possibly significantly less, than the stated principal amount per Trigger PLUS if you try to sell your Trigger PLUS prior to maturity.

￭The Trigger PLUS 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 Trigger PLUS. You are dependent on our ability to pay all amounts due on the Trigger PLUS at maturity and therefore you are subject to our credit risk. If we default on our obligations under the Trigger PLUS, your investment would be at risk and you could lose some or all of your investment. As a result, the market value of the Trigger PLUS 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 Trigger PLUS.

￭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.

￭Investing in the Trigger PLUS is not equivalent to investing in the underlying shares or the stocks composing the share underlying index. Investing in the Trigger PLUS is not equivalent to investing in the underlying shares, the share underlying index or the stocks that constitute the share underlying index. Investors in the Trigger PLUS will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the underlying shares or the stocks that constitute the share underlying index.

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

￭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 Trigger PLUS in the original issue price reduce the economic terms of the Trigger PLUS, cause the estimated value of the Trigger PLUS 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 Trigger PLUS 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 Trigger PLUS in the original issue price and the lower rate we are willing to pay as issuer make the economic terms of the Trigger PLUS less favorable to you than they otherwise would be.

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

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

￭The calculation agent, which is a subsidiary of Morgan Stanley and an affiliate of MSFL, will make determinations with respect to the Trigger PLUS. As calculation agent, MS & Co. will determine the initial share price, the trigger level and the final share price, including whether the share price has decreased to below the trigger level, and will calculate the amount of cash, if any, 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 final share price in the event of a discontinuance of the underlying shares or a market disruption event. These potentially subjective determinations may adversely affect the payout to you at maturity, if any. For further information regarding these types of determinations, see “Description of PLUS—Postponement of Valuation Date(s),” “—Discontinuance of Any ETF Shares and/or Share Underlying Index; Alteration of Method of Calculation,” “—Alternate Exchange Calculation in case of an Event of Default” and “—Calculation Agent and Calculations” in the accompanying product supplement. In addition, MS & Co. has determined the estimated value of the Trigger PLUS on the pricing date.

￭Hedging and trading activity by our affiliates could potentially adversely affect the value of the Trigger PLUS. One or more of our affiliates and/or third-party dealers expect to carry out hedging activities related to the Trigger PLUS (and to other instruments linked to the underlying shares or the share underlying index), including trading in the underlying shares and in other instruments related to the underlying shares or the share underlying index. As a result, these entities may be unwinding or adjusting hedge positions during the term of the Trigger PLUS, and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the valuation date approaches. MS & Co. and some of our other affiliates also trade the underlying shares or the stocks that constitute the share underlying index and other financial instruments related to the share 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 share price, and, therefore, could increase the trigger level, which is the level at or above which the underlying shares must close on the valuation date so that investors do not suffer a significant loss on their initial investment in the Trigger PLUS. Additionally, such hedging or trading activities during the term of the Trigger PLUS, including on the valuation date, could adversely affect the closing price of the underlying shares on the valuation date, and, accordingly, the amount of cash an investor will receive at maturity, if any.

￭The U.S. federal income tax consequences of an investment in the Trigger PLUS 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 PLUS (together, the “Tax Disclosure Sections”) concerning the U.S. federal income tax consequences of an investment in the Trigger PLUS. As discussed in the Tax Disclosure Sections, there is a substantial risk that the “constructive ownership” rule could apply, in which case all or a portion of any long-term capital gain recognized by a U.S. Holder could be recharacterized as ordinary income and an interest charge could be imposed. If the Internal Revenue Service (the “IRS”) were successful in asserting an alternative treatment, the timing and character of income on the Trigger PLUS might differ significantly from the tax treatment described in the Tax Disclosure Sections. For example, under one possible treatment, the IRS could seek to recharacterize the Trigger PLUS as debt instruments. In that event, U.S. Holders would be required to accrue into income original issue discount on the Trigger PLUS every year at a “comparable yield” determined at the time of issuance and recognize all income and gain in respect of the Trigger PLUS as ordinary income. The risk that financial instruments providing for buffers, triggers or similar downside protection features, such as the Trigger PLUS, would be recharacterized as debt is greater than the risk of recharacterization for comparable financial instruments that do not have such features. We do not plan to request a ruling from the IRS regarding the tax treatment of the Trigger PLUS, and the IRS or a court may not agree with the tax treatment described in the Tax Disclosure Sections.

In 2007, the U.S. Treasury Department and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. The notice focuses in particular on whether to require holders of these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments; whether short-term instruments should be subject to any such accrual regime; the relevance of factors such as the exchange-traded status of the instruments and the nature of the underlying property to which the instruments are linked; the degree, if any, to which income (including any mandated accruals) realized by non-U.S. investors should be subject to withholding tax; and whether these instruments are or should be subject to the “constructive ownership” rule, as discussed in this document. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of

these issues could materially and adversely affect the tax consequences of an investment in the Trigger PLUS, possibly with retroactive effect. 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 Trigger PLUS, including possible alternative treatments, the potential application of the constructive ownership rule, the issues presented by this notice and any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Risks Relating to the Underlying Shares

￭The performance and market price of the Fund, particularly during periods of market volatility, may not correlate with the performance of the share underlying index, the performance of the component securities of the share underlying index or the net asset value per share of the Fund. The Fund does not fully replicate the share underlying index and may hold securities that are different than those included in the share underlying index.  In addition, the performance of the Fund will reflect additional transaction costs and fees that are not included in the calculation of the share underlying index.  All of these factors may lead to a lack of correlation between the performance of the Fund and the share underlying index.  In addition, corporate actions (such as mergers and spin-offs) with respect to the equity securities underlying the Fund may impact the variance between the performances of the Fund and the share underlying index.  Finally, because the shares of the Fund are traded on  an exchange and are subject to market supply and investor demand, the market price of one share of the Fund may differ from the net asset value per share of the Fund.

In particular, during periods of market volatility, or unusual trading activity, trading in the securities underlying the Fund may be disrupted or limited, or such securities may be unavailable in the secondary market.  Under these circumstances, the liquidity of the Fund may be adversely affected, market participants may be unable to calculate accurately the net asset value per share of the Fund, and their ability to create and redeem shares of the Fund may be disrupted. Under these circumstances, the market price of shares of the Fund may vary substantially from the net asset value per share of the Fund or the level of the share underlying index.

For all of the foregoing reasons, the performance of the Fund may not correlate with the performance of the share underlying index, the performance of the component securities of the share underlying index or the net asset value per share of the Fund.  Any of these events could materially and adversely affect the price of the shares of the Fund and, therefore, the value of the Trigger PLUS.  Additionally, if market volatility or these events were to occur on the valuation date, the calculation agent would maintain discretion to determine whether such market volatility or events have caused a market disruption event to occur, and such determination would affect the payment at maturity of the Trigger PLUS.  If the calculation agent determines that no market disruption event has taken place, the payment at maturity would be based solely on the published closing price per share of the Fund on the valuation date, even if the Fund’s shares are underperforming the share underlying index or the component securities of the share underlying index and/or trading below the net asset value per share of the Fund.

￭Adjustments to the underlying shares or to the share underlying index could adversely affect the value of the Trigger PLUS. As the investment adviser to the Fund, State Street Global Advisors (the “Investment Adviser”), seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the share underlying index. Pursuant to its investment strategy or otherwise, the Investment Adviser may add, delete or substitute the stocks composing the Fund. Any of these actions could adversely affect the price of the underlying shares and, consequently, the value of the Trigger PLUS. S&P® Dow Jones Indices LLC (“S&P®”) is responsible for calculating and maintaining the share underlying index. S&P® may add, delete or substitute the stocks constituting the share underlying index or make other methodological changes that could change the value of the share underlying index. S&P® may discontinue or suspend calculation or publication of the share underlying index at any time. If trading in the underlying shares is permanently discontinued and/or the Fund is liquidated or otherwise terminated, and S&P® subsequently discontinues publication of the share underlying index, the calculation agent will have the sole discretion to substitute a successor index that is comparable to the discontinued share underlying index and is permitted to consider indices that are calculated and published by the calculation agent or any of its affiliates. Any of these actions could adversely affect the price of the underlying shares, and consequently, the value of the Trigger PLUS.

￭The antidilution adjustments the calculation agent is required to make do not cover every event that could affect the underlying shares. MS & Co., as calculation agent, will adjust the adjustment factor for certain events affecting the underlying shares. However, the calculation agent will not make an adjustment for every event that

could affect the underlying shares. If an event occurs that does not require the calculation agent to adjust the adjustment factor, the market price of the Trigger PLUS may be materially and adversely affected.

SPDR® S&P 500® ETF Trust Overview

The SPDR® S&P 500® ETF Trust (formerly SPDR Trust, Series 1), or SPY, formed by PDR Services LLC, is a unit investment trust registered under the Investment Company Act of 1940 that holds a portfolio of securities consisting of substantially all of the common stocks, in substantially the same weighting, as the S&P 500® Index. SPY seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P 500® Index. The SPDR® S&P 500® ETF Trust is managed by State Street Global Advisors Trust Company (“SSGA”), a registered investment company that consists of numerous separate investment portfolios, including the SPDR® S&P 500® ETF Trust. It is possible that this fund may not fully replicate the performance of the S&P 500® Index due to the temporary unavailability of certain securities in the secondary market or due to other extraordinary circumstances. Information provided to or filed with the Securities and Exchange Commission (the “Commission”) by SSGA pursuant to the Securities Act of 1933 and the Investment Company Act of 1940 can be located by reference to Commission file numbers 033-46080 and 811-06125, respectively, through the Commission’s website at www.sec.gov.

Additional Information About the Trigger PLUS

Additional Information:
Additional information related to calculating the final share price:	If a market disruption event occurs with respect to the underlying shares, the calculation agent may determine the final share price in accordance with the procedures set forth in the product supplement for PLUS. You should refer to the section “Description of PLUS—Share Closing Price” in the product supplement for PLUS for more information. If the underlying shares are subject to a stock split or reverse stock split, the calculation agent may make the antidilution adjustments in accordance with the procedures set forth in the product supplement for PLUS. You should refer to the section “Description of PLUS—Antidilution Adjustments for PLUS linked to Exchange-Traded Funds” in the product supplement for PLUS for more information. If no closing price of the underlying shares is available on the valuation date through discontinuance or liquidation of the Fund, the calculation agent may determine the final share price in accordance with the procedures set forth in the product supplement for PLUS. You should refer to the section “Description of PLUS—Discontinuance of Any ETF Shares and/or Share Underlying Index; Alteration of Method of Calculation” in the product supplement for PLUS for more information.
Minimum ticketing size:	$1,000 / 1 Trigger PLUS
Tax considerations:	Although there is uncertainty regarding the U.S. federal income tax consequences of an investment in the Trigger PLUS 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, a Trigger PLUS should be treatedas a single financial contract that is an “open transaction” for U.S. federal income tax purposes. Assuming this treatment of the Trigger PLUS is respected and subject to the discussion in “United States Federal Taxation” in the accompanying product supplement for PLUS, 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 Trigger PLUS prior to settlement, other than pursuant to a sale or exchange. ￭Upon sale, exchange or settlement of the Trigger PLUS, 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 Trigger PLUS. Subject to the discussion below concerning the potential application of the “constructive ownership” rule, such gain or loss should be long-term capital gain or loss if the investor has held the Trigger PLUS for more than one year, and short-term capital gain or loss otherwise. Because the Trigger PLUS are linked to shares of an exchange-traded fund, although the matter is not clear, there is a substantial risk that an investment in the Trigger PLUS will be treated as a “constructive ownership transaction” under Section 1260 of the Internal Revenue Code of 1986, as amended (the “Code”). If this treatment applies, all or a portion of any long-term capital gain of the U.S. Holder in respect of the Trigger PLUS could be recharacterized as ordinary income (in which case an interest charge will be imposed). As a result of certain features of the Trigger PLUS, including the leveraged upside payment, it is unclear how to calculate the amount of gain that would be recharacterized if an investment in the Trigger PLUS were treated as a constructive ownership transaction. Due to the lack of governing authority, our counsel is unable to opine as to whether or how Section 1260 of the Code applies to the Trigger PLUS. U.S. investors should read the section entitled “United States Federal Taxation—Tax Consequences to U.S. Holders—Possible Application of Section 1260 of the Code” in the accompanying product supplement for PLUS for additional information and consult their tax advisers regarding the potential application of the “constructive ownership” rule. In2007, the U.S. Treasury Department and the Internal Revenue Service (the “IRS”) released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. The notice focuses in particular on whether to require holders of these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments; whether short-term instruments should be subject to any such accrual regime; the relevance of factors such as the exchange-traded status of the instruments and the nature of the underlying property to which the instruments are linked; the degree, if any, to which income (including any mandated accruals) realized by non-U.S. investors should be subject to

Morgan Stanley Finance LLC

Trigger PLUS Based on the Performance of theSPDR® S&P 500® ETF Trust due December 20, 2028

Principal at Risk Securities

withholding tax; and whether these instruments are or should be subject to the “constructive ownership” rule, as discussed above. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the Trigger PLUS, possibly with retroactive effect. As discussed in the accompanying product supplement for PLUS, Section 871(m) of the Code and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% (or a lower applicable treaty rate) withholding tax on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities (each, an “Underlying Security”). Subject to certain exceptions, Section 871(m) generally applies to securities that substantially replicate the economic performance of one or more Underlying Securities, as determined based on tests set forth in the applicable Treasury regulations (a “Specified Security”). However, pursuant to an IRS notice, Section 871(m) will not apply to securities issued before January 1, 2025 that do not have a delta of one with respect to any Underlying Security. Based on our determination that the Trigger PLUS do not have a delta of one with respect to any Underlying Security, our counsel is of the opinion that the Trigger PLUS 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 Trigger PLUS. Both U.S. and non-U.S. investors considering an investment in the Trigger PLUS should read the discussion under “Risk Factors” in this document and the discussion under “United States Federal Taxation” in the accompanying product supplement for PLUS and consult their tax advisers regarding all aspects of the U.S. federal income tax consequences of an investment in the Trigger PLUS, including possible alternative treatments, the potential application of the constructive ownership rule, the issues presented by the aforementioned notice 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 PLUS, 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 Trigger PLUS.

Use of proceeds and hedging:

The proceeds from the sale of the Trigger PLUS will be used by us for general corporate purposes. We will receive, in aggregate, $1,000 per Trigger PLUS issued, because, when we enter into hedging transactions in order to meet our obligations under the Trigger PLUS, our hedging counterparty will reimburse the cost of the agent’s commissions. The costs of the Trigger PLUS borne by you and described beginning on page 2 above comprise the agent’s commissions and the cost of issuing, structuring and hedging the Trigger PLUS. On or prior to the pricing date, we will hedge our anticipated exposure in connection with the Trigger PLUS by entering into hedging transactions with our affiliates and/or third-party dealers. We expect our hedging counterparties to take positions in the underlying shares and in futures and options contracts on the underlying shares or any component stocks of the share underlying index, or in any other securities or instruments that they may wish to use in connection with such hedging. Such purchase activity could potentially increase the price of the underlying shares on the pricing date, and therefore could increase the trigger level, which is the level at or above which the underlying shares must close on the valuation date so that investors do not suffer a significant loss on their initial investment in the Trigger PLUS. In addition, through our affiliates, we are likely to modify our hedge position throughout the term of the Trigger PLUS, including on the valuation date, by purchasing and selling the underlying shares, futures or options contracts on the underlying shares or component stocks of the share underlying index 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 Trigger PLUS, and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the valuation date approaches. We cannot give any assurance that our hedging activities will not affect the value of

	the underlying shares, and, therefore, adversely affect the value of the Trigger PLUS or the payment 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 for PLUS.
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 Trigger PLUS, either directly or indirectly.
Supplemental information regarding plan of distribution; conflicts of interest:	MS & Co. expects to sell all of the Trigger PLUS that it purchases from us to an unaffiliated dealer at a price of $992.50 per Trigger PLUS, for further sale to certain fee-based advisory accounts at the price to public of $1,000 per Trigger PLUS. MS & Co. will not receive a sales commission with respect to the Trigger PLUS. 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 Trigger PLUS. 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 for PLUS.
Validity of the Trigger PLUS:	In the opinion of Davis Polk & Wardwell LLP, as special counsel to MSFL and Morgan Stanley, when the Trigger PLUS offered by this pricing supplement have been executed and issued by MSFL, authenticated by the trustee pursuant to the MSFL Senior Debt Indenture (as defined in the accompanying prospectus) and delivered against payment as contemplated herein, such Trigger PLUS will be valid and binding obligations of MSFL and the related guarantee will be a valid and binding obligation of Morgan Stanley, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability (including, without limitation, concepts of good faith, fair dealing and the lack of bad faith), provided that such counsel expresses no opinion as to (i) the effect of fraudulent conveyance, fraudulent transfer or similar provision of applicable law on the conclusions expressed above and (ii) any provision of the MSFL Senior Debt Indenture that purports to avoid the effect of fraudulent conveyance, fraudulent transfer or similar provision of applicable law by limiting the amount of Morgan Stanley’s obligation under the related guarantee. This opinion is given as of the date hereof and is limited to the laws of the State of New York, the General Corporation Law of the State of Delaware and the Delaware Limited Liability Company Act. In addition, this opinion is subject to customary assumptions about the trustee’s authorization, execution and delivery of the MSFL Senior Debt Indenture and its authentication of the Trigger PLUS and the validity, binding nature and enforceability of the MSFL Senior Debt Indenture with respect to the trustee, all as stated in the letter of such counsel dated November 16, 2023, which is Exhibit 5-a to the Registration Statement on Form S-3 filed by Morgan Stanley on November 16, 2023.
