Principal at Risk Securities Linked to the SPDR® S&P® Oil & Gas Exploration & Production ETF due November 4, 2027

Fully and Unconditionally Guaranteed by Morgan Stanley

￭Linked to the SPDR® S&P® Oil & Gas Exploration & Production ETF (the “underlying”)

￭The securities offered are unsecured obligations of Morgan Stanley Finance LLC (“MSFL”) and are fully and unconditionally guaranteed by Morgan Stanley. Unlike ordinary debt securities, the securities do not pay interest, do not guarantee the repayment of principal and are subject to potential automatic call prior to the maturity date upon the terms described below. The securities have the terms described in the accompanying product supplement for principal at risk securities and prospectus, as supplemented or modified by this document.

￭Automatic Call. The securities will be automatically called if the fund closing price of the underlying on any of the calculation days is greater than or equal to 90% of the starting price, which we refer to as the call threshold price, for a call payment equal to the face amount plus a call premium. The call premium applicable to each calculation day will be a percentage of the face amount that increases for each calculation day based on a simple (non-compounding) return of at least approximately 10.50% per annum (to be determined on the pricing date). No further payments will be made on the securities once they have been called.

￭Maturity Payment Amount. If the securities are not automatically called, you will receive at maturity a cash payment per security as follows: If the ending price of the underlying is less than the threshold price, investors will be exposed to the decline in the underlying beyond 10%, and investors will lose some or a significant portion of their initial investment.

￭The maturity payment amount may be significantly less than the face amount, and you could lose up to 90% of your investment.

￭The securities are for investors who are willing to forgo current income and participation in the appreciation of the underlying in exchange for the possibility of receiving a call payment if the underlying closes at or above the call threshold price on any of the calculation days, including the final calculation day.

￭Investors will not participate in any appreciation of the underlying.

￭The securities 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 securities are not secured obligations and you will not have any security interest in, or otherwise have any access to, any securities included in the underlying.

The current estimated value of the securities is approximately $953.70 per security, or within $45.00 of that estimate. The estimated value of the securities is determined using our own pricing and valuation models, market inputs and assumptions relating to the underlying, instruments based on the underlying, 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. See “Estimated Value of the Securities” on page 4.

The securities have complex features and investing in the securities involves risks not associated with an investment in ordinary debt securities. See “Risk Factors” beginning on page 10. All payments on the securities are subject to our credit risk.

The Securities and Exchange Commission and state securities regulators have not approved or disapproved these securities, or determined if this document or the accompanying product supplement and prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The securities are not deposits or savings accounts and are not insured by the Federal Deposit Insurance Corporation or any other governmental agency or instrumentality, nor are they obligations of, or guaranteed by, a bank.

Estimated Value of the Securities

The face amount 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 per security. We estimate that the value of each security on the pricing date will be approximately $953.70, or within $45.00 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. The estimated value of the securities is determined using our own pricing and valuation models, market inputs and assumptions relating to the underlying, instruments based on the underlying, 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 call payment amounts, the call threshold price and the threshold price, 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, 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 3 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, 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.

Investor Considerations

The Principal at Risk Securities Linked to the SPDR® S&P® Oil & Gas Exploration & Production ETF due November 4, 2027 (the “securities”) may be appropriate for investors who:

￭Believe that the fund closing price of the underlying will be greater than or equal to the call threshold price on one of the calculation days;

￭Seek the potential for a fixed return if the underlying is greater than or equal to the call threshold price as of any of the calculation days in lieu of full participation in any potential appreciation of the underlying;

￭Understand that if the fund closing price of the underlying is less than the call threshold price on each calculation day, they will not receive any positive return on their investment in the securities, and that if the fund closing price of the underlying on the final calculation day has declined by more than 10% from the starting price, they will receive less, and possibly 90% less, than the face amount per security at maturity;

￭Understand that the term of the securities may be as short as approximately one year, and that they will not receive a higher call payment with respect to a later calculation day if the securities are called on an earlier calculation day;

￭Are willing to forgo interest payments on the securities and dividends on the underlying and the stocks composing the fund underlying index; and

￭Are willing to hold the securities until maturity.

The securities are not designed for, and may not be an appropriate investment for, investors who:

￭Seek a liquid investment or are unable or unwilling to hold the securities to maturity;

￭Require full payment of the face amount of the securities at maturity;

￭Believe that the fund closing price of the underlying will be less than the call threshold price on each calculation day;

￭Seek a security with a fixed term;

￭Are unwilling to accept the risk that, if the fund closing price of the underlying is less than the call threshold price on each calculation day, they will not receive any positive return on their investment in the securities;

￭Are unwilling to accept the risk that the fund closing price of the underlying on the final calculation day may decline by more than 10% from the starting price to the ending price, in which case they will receive less, and possibly 90% less, than the face amount per security at maturity;

￭Seek current income;

￭Are unwilling to accept the risk of exposure to the underlying;

￭Seek exposure to the upside performance of the underlying beyond the applicable call premiums;

￭Are unwilling to accept our credit risk; or

￭Prefer the lower risk of fixed income investments with comparable maturities issued by companies with comparable credit ratings.

The considerations identified above are not exhaustive. Whether or not the securities are an appropriate investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisors have carefully considered the appropriateness of an investment in the securities in light of your particular circumstances. You should also review carefully the “Risk Factors” herein and in the accompanying product supplement for risks related to an investment in the securities. For more information about the underlying, please see the section titled “SPDR® S&P® Oil & Gas Exploration & Production ETF Overview” below.

Scenario Analysis and Examples of Hypothetical Payments on the Securities

The following scenario analysis and examples are provided for illustrative purposes only and are hypothetical. Whether the securities are called will be determined by reference to the fund closing price of the underlying on the calculation days, and the maturity payment amount, if any, will be determined by reference to the fund closing price of the underlying on the final calculation day. The actual call payment with respect to each applicable calculation day, starting price, call threshold price and threshold price 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*:

Investment term: Approximately 3 years

Hypothetical call payments: The hypothetical call payment will be an amount in cash per face amount for each calculation day, as follows:

Call Payment

●1st calculation day: $1,105.00

●2nd calculation day: $1,157.50

●3rd calculation day: $1,210.00

●4th calculation day: $1,262.50

●Final calculation day: $1,315.00

Hypothetical starting price: $100.00

Hypothetical call threshold price: $90.00, which is 90% of the hypothetical starting price

Hypothetical threshold price: $90.00, which is 90% of the hypothetical starting price

* The hypothetical starting price of $100 for the underlying has been chosen for illustrative purposes only and does not represent the actual starting price of the underlying. The actual starting price, call threshold price and threshold price will be determined on the pricing date and will be set forth under “Terms” above. For historical data regarding the actual closing prices of the underlying, see the historical information set forth herein.

Automatic Call:

Example 1 — the securities are called following the second calculation day


Date	Fund Closing Price	Payment (per Security)
1st Calculation day	$80.00 (below the call threshold price)	--
2nd Calculation day	$150.00 (at or above the call threshold price)	$1,157.50

In this example, on the first calculation day, the fund closing price of the underlying is below the call threshold price. Therefore, the securities are not called. On the second calculation day, the fund closing price of the underlying is at or above the call threshold price. Therefore, the securities are automatically called on the second call settlement date. Investors will receive a payment of $1,157.50 per security on the related call settlement date. No further payments will be made on the securities once they have been called, and investors do not participate in the appreciation in the underlying.

How to calculate the payment investors will receive at maturity:

In the following example, the fund closing price of the underlying is below the call threshold price on each of the calculation days, and, consequently, the securities are not automatically called.

Example 1 — the ending price is below the call threshold price


Date	Fund Closing Price	Payment (per Security)
1st Calculation day	$67.00 (below the call threshold price, securities are not called)	--

October 2024 Page 8

Morgan Stanley Finance LLC

Market Linked Securities— Auto-Callable with Fixed Percentage Buffered Downside

Principal at Risk Securities Linked to the SPDR® S&P® Oil & Gas Exploration & Production ETF due November 4, 2027


2nd Calculation day	$60.00 (below the call threshold price, securities are not called)	--
3rd Calculation day	$88.00 (below the call threshold price, securities are not called)	--
4th Calculation day	$78.00 (below the call threshold price, securities are not called)	--
Final Calculation day	$40.00 (below the threshold price)

In this example, the fund closing price of the underlying is below the call threshold price on each of the calculation days, and therefore the securities are not called. On the final calculation day, the ending price is below the threshold price, and accordingly, investors are exposed to the negative performance of the underlying beyond 10% and will receive a maturity payment amount that is less than the face amount of the securities. The maturity payment amount is $500.00 per security, representing a loss of 50% on your investment over the 3-year term of the securities.

If the securities are not called prior to maturity and the ending price is below the threshold price on the final calculation day, the securities will be exposed to any decline in the fund closing price of the underlying beyond 10%. You may lose up to 90% of the face amount of your securities at maturity.

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 for principal at risk securities and prospectus. We also urge you to consult 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 the face amount of your securities at maturity. The terms of the securities differ from those of ordinary debt securities in that they do not pay interest or guarantee the return of the face amount of your securities at maturity. If the securities have not been automatically called and if the ending price of the underlying is less than the threshold price, you will receive less, and up to 90% less, than the face amount of your securities at maturity.

￭The appreciation potential of the securities is limited by the call payment specified for each calculation day. The appreciation potential of the securities is limited to the call payment specified for each calculation day if the underlying closes at or above the call threshold price on any calculation day. In all cases, you will not participate in any appreciation of the underlying, which could be significant.

￭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 on any day, including in relation to the starting price, the call threshold price and threshold price, will affect the value of the securities more than any other factors. Other factors that may influence the value of the securities include:

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

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

odividend rates on the underlying or the stocks composing the fund underlying index,

othe time remaining until the securities mature,

ointerest and yield rates in the market,

othe availability of comparable instruments,

othe occurrence of certain events affecting the underlying that may or may not require an adjustment to the adjustment factor, 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. For example, you may have to sell your securities at a substantial discount from the face amount of $1,000 per security if the price of the underlying at the time of sale is near or below its threshold price or if market interest rates rise.

You cannot predict the future performance of the underlying based on its historical performance. If the securities are not called and the ending price is less than the threshold price, you will be exposed on a 1-to-1 basis to any decline in the ending price in excess of 10%. See “SPDR® S&P® Oil & Gas Exploration & Production ETF 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 automatic call 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

October 2024 Page 10

Morgan Stanley Finance LLC

Market Linked Securities— Auto-Callable with Fixed Percentage Buffered Downside

Principal at Risk Securities Linked to the SPDR® S&P® Oil & Gas Exploration & Production ETF due November 4, 2027

some or all of 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.

￭Investing in the securities is not equivalent to investing in the underlying or the stocks composing the fund underlying index. Investing in the securities is not equivalent to investing in the underlying, the fund underlying index or the stocks that constitute the fund underlying index. Investors in the securities will not participate in any positive performance of the underlying, and will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the underlying or the stocks that constitute the fund underlying index.

￭Reinvestment risk. The term of your investment in the securities may be shortened due to the automatic call feature of the securities. If the securities are called 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.

￭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 face amount reduce the economic terms of the securities, cause the estimated value of the securities to be less than the face amount 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 face amount, because secondary market prices will exclude the issuing, selling, structuring and hedging-related costs that are included in the face amount 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 face amount 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.

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 3 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, 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

Morgan Stanley Finance LLC

Market Linked Securities— Auto-Callable with Fixed Percentage Buffered Downside

Principal at Risk Securities Linked to the SPDR® S&P® Oil & Gas Exploration & Production ETF due November 4, 2027

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.

￭The securities will not be listed on any securities exchange and secondary trading may be limited. The securities will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the securities. MS & Co. and WFS may, but are not obligated to, make a market in the securities and, if either of them once chooses to make a market, may cease doing so at any time. When they do make a market, they will generally do so for transactions of routine secondary market size at prices based on their respective estimates of the current value of the securities, taking into account their respective bid/offer spreads, 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 they 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. or WFS is willing to transact. If, at any time, MS & Co. and WFS 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.

￭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 starting price, the call threshold price, the threshold price and the ending price and will calculate the amount of cash you 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 ending price in the event of a market disruption event or certain adjustments to the adjustment factor. These potentially subjective determinations may adversely affect the payout to you at maturity. For further information regarding these types of determinations, see “General Terms of the Securities—Market Disruption Events,” “—Anti-dilution Adjustments Relating to a Fund; Alternate Calculation,” “—Consequences of a Market Disruption Event; Postponement of a Calculation Day” and “Alternate Exchange Calculation in Case of an Event of Default” in the accompanying product supplement for principal at risk securities. In addition, MS & Co. has determined the estimated value of the securities on the pricing date.

￭Hedging and trading activity by our affiliates could potentially adversely 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 possibly to other instruments linked to the underlying or the fund underlying index), including trading in the underlying and in other instruments related to the underlying or fund 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 calculation day approaches. Some of our affiliates also trade the underlying or the stocks that constitute the fund underlying index and other financial instruments related to the fund underlying index and other financial instruments related to the underlying 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 affect the starting price, and, therefore, could increase (i) the price at or above which the underlying must close on the calculation days so that the securities are called for the call payment and (ii) the threshold price for the underlying, which is the price at or above which the underlying must close on the final calculation day so that you do not suffer a loss on your initial investment in the securities. Additionally, such hedging or trading activities during the term of the securities could potentially affect the value of the underlying on the calculation days, and, accordingly, whether we call the securities prior to maturity and the amount of cash you will receive at maturity.

￭The maturity date may be postponed if the final calculation day is postponed. If the scheduled final calculation day is not a trading day or if a market disruption event occurs on that day so that the final calculation day is postponed and falls less than three business days prior to the maturity date, the maturity date of the securities will be postponed to the third business day following that final calculation day as postponed.

￭Potentially inconsistent research, opinions or recommendations by Morgan Stanley, MSFL, WFS or our or their respective affiliates. Morgan Stanley, MSFL, WFS and our or their respective affiliates may publish research from time to time on financial markets and other matters that may influence the value of the securities, or express opinions or provide recommendations that are inconsistent with purchasing or holding the securities. Any research, opinions or recommendations expressed by Morgan Stanley, MSFL, WFS or our or their respective affiliates may not be consistent with each other and may be modified from time to time without notice. Investors should make their own independent investigation of the merits of investing in the securities and the underlying to which the securities are linked.

￭The U.S. federal income tax consequences of an investment in the securities are uncertain. Please read the discussion under “Additional Information About the Securities—Tax considerations” in this document and the discussion under “United States Federal Taxation” in the accompanying product supplement for principal at risk securities (together, the “Tax Disclosure Sections”) concerning the U.S. federal income tax consequences of an investment in the securities. As discussed in the Tax Disclosure Sections, there is a 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. In addition, 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

￭Investing in the securities exposes investors to risks associated with investments in securities with a concentration in the oil and gas exploration and production sector. The stocks included in the fund underlying index and that are generally tracked by the underlying are stocks of companies whose primary business is associated with the exploration and production of oil and gas. As a result, the value of the securities may be subject to greater volatility and may be more adversely affected by a single economic, political or regulatory occurrence affecting this industry than a different investment linked to securities of a more broadly diversified group of issuers or issuers in a less volatile industry. The oil and gas industry is significantly affected by a number of factors that influence worldwide economic conditions and oil and gas prices, such as natural disasters, supply disruptions, geopolitical events and other factors that may offset or magnify each other, including:

oworldwide and domestic supplies of, and demand for, crude oil and natural gas;

othe cost of exploring for, developing, producing, refining and marketing crude oil and natural gas;

oconsumer confidence;

ochanges in weather patterns and climatic changes;

othe ability of the members of Organization of Petroleum Exporting Countries (OPEC) and other producing nations to agree to and maintain production levels;

othe worldwide military and political environment, uncertainty or instability resulting from an escalation or additional outbreak of armed hostilities or further acts of terrorism in the United States, or elsewhere;

othe price and availability of alternative and competing fuels;

odomestic and foreign governmental regulations and taxes;

oemployment levels and job growth; and

ogeneral economic conditions worldwide.

These or other factors or the absence of such factors could cause a downturn in the oil and natural gas industries generally or regionally and could cause the value of some or all of the component stocks included in the fund underlying index to decline during the term of the securities.

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

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

For all of the foregoing reasons, the performance of the underlying may not correlate with the performance of the fund underlying index, the performance of the component securities of the fund underlying index or the net asset value per share of the underlying. Any of these events could materially and adversely affect the price of the shares of the underlying and, therefore, the value of the securities. Additionally, if market volatility or these events were to occur on the final calculation day, 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 may affect the payment at maturity of the securities. If the calculation agent determines that no market disruption event has taken place, the payment at maturity would be based on the published closing price per share of the underlying on the final calculation day, even if the underlying’s shares are underperforming the fund underlying index or the component securities of the fund underlying index and/or trading below the net asset value per share of the underlying.

￭Adjustments to the underlying or the fund underlying index could adversely affect the value of the securities. The investment adviser to the underlying seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the fund underlying index. The investment adviser for the underlying is SSGA Funds Management, Inc. Pursuant to its investment strategy or otherwise, the investment adviser may add, delete or substitute the stocks composing the underlying shares. The sponsor of the fund underlying index is responsible for calculating and maintaining the fund underlying index. The sponsor may add, delete or substitute the stocks constituting the fund underlying index or make other methodological changes that could change the value of the fund underlying index, and, consequently, the price of the underlying shares and the value of the securities. The sponsor of the fund underlying index may discontinue or suspend calculation or publication of a fund underlying index at any time. In these circumstances, the calculation agent will have the sole discretion to substitute a successor index that is comparable to the discontinued fund underlying index and will be 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 securities.

￭The antidilution adjustments the calculation agent is required to make do not cover every event that could affect the shares of the underlying. MS & Co., as calculation agent, will adjust the adjustment factor for certain events affecting the underlying. However, the calculation agent will not make an adjustment for every event that could affect the underlying. If an event occurs that does not require the calculation agent to adjust the adjustment factor, the market price of the securities may be materially and adversely affected. The determination by the calculation agent to adjust, or not to adjust, the adjustment factor may materially and adversely affect the value of the securities.

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 principal at risk 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. 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 securities for more than one year, and short-term capital gain or loss otherwise.

Because the securities are linked to shares of an exchange-traded fund, although the matter is not clear, there is a risk that an investment in the securities 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 securities could be recharacterized as ordinary income (in which case an interest charge will be imposed). 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 securities. 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 principal at risk securities for additional information and consult their tax advisers regarding the potential application of the “constructive ownership” rule.

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 principal at risk securities, Section 871(m) of the Code and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% (or a lower applicable treaty rate) withholding tax on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities (each, an “Underlying Security”). Subject to certain exceptions, Section 871(m) generally applies to securities that substantially replicate the economic performance of one or more Underlying Securities, as determined based on tests set forth in the applicable Treasury regulations (a “Specified Security”). However, pursuant to an IRS notice, Section 871(m) will not apply to securities issued before January 1, 2027 that do not have a delta of one with respect to any Underlying Security. Based on the terms of the securities and current market conditions, we expect that the securities will not have a delta of one with respect to any Underlying Security on the pricing date. However, we will provide an updated determination in the final 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 principal at risk 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, the potential application of the constructive ownership rule, 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 principal at risk 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.

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.
