Principal at Risk Securities

￭The securities are unsecured obligations of Morgan Stanley Finance LLC (“MSFL”) and are fully and unconditionally guaranteed by Morgan Stanley. The securities have the terms described in the accompanying product supplement, index supplement and prospectus, as supplemented or modified by this document. The securities do not provide for the regular payment of interest.

￭Contingent coupon. The securities will pay a contingent coupon but only if the closing level of each underlier is greater than or equal to its coupon barrier level on the related observation date. However, if the closing level of either underlier is less than its coupon barrier level on any observation date, we will pay no interest with respect to the related interest period.

￭Call feature. We will redeem the securities on any redemption date for a redemption payment equal to the stated principal amount plus any contingent coupon otherwise due with respect to the related interest period, if and only if the output of a risk neutral valuation model on a business day, as selected by the calculation agent, that is no earlier than three business days before the observation date preceding such redemption date and no later than such observation date, based on the inputs indicated under “Call feature” below, indicates that redeeming on such date is economically rational for us as compared to not redeeming on such date. An early redemption of the securities will not automatically occur based on the performance of the underliers. No further payments will be made on the securities once they have been redeemed.

￭Payment at maturity. If the securities have not been redeemed prior to maturity and the final level of each underlier is greater than or equal to its buffer level, investors will receive (in addition to the contingent coupon with respect to the final observation date, if payable) the stated principal amount at maturity. If, however, the final level of either underlier is less than its buffer level, investors will lose 1% for every 1% decline in the level of the worst performing underlier beyond the specified buffer amount. Under these circumstances, the payment at maturity will be less, and may be significantly less, than the stated principal amount of the securities, subject to the minimum payment at maturity.

￭The value of the securities is based on the worst performing underlier. The fact that the securities are linked to more than one underlier does not provide any asset diversification benefits and instead means that a decline in the level of either underlier beyond its coupon barrier level and/or buffer level will adversely affect your return on the securities, even if the other underlier has appreciated or has not declined as much.

￭The securities are for investors who are willing to risk their principal and accept the risk of receiving no coupons over the entire term of the securities and the risk of an early redemption of the securities based on the output of a risk neutral valuation model in exchange for the buffer feature and the opportunity to earn interest at a potentially above-market rate. You will not participate in any appreciation of either underlier. Investors in the securities must be willing to accept the risk of losing a significant portion of their initial investment based on the performance of either underlier. 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 underlying reference asset or assets.

Estimated Value of the Securities

The original issue price of each security is $1,000. This price includes costs associated with issuing, selling, structuring and hedging the securities, which are borne by you, and, consequently, the estimated value of the securities on the pricing date is less than $1,000. Our estimate of the value of the securities as determined on the pricing date is set forth on the cover of this document.

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 underliers. The estimated value of the securities is determined using our own pricing and valuation models, market inputs and assumptions relating to the underliers, instruments based on the underliers, 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, 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 underliers, 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, to the extent that MS & Co. may buy or sell the securities in the secondary market during the amortization period specified herein, absent changes in market conditions, including those related to the underliers, 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.

Hypothetical Examples

The following hypothetical examples illustrate how to determine whether a contingent coupon is payable with respect to an observation date and how to calculate the payment at maturity if we do not redeem the securities based on the output of a risk neutral valuation model prior to maturity. The following examples are for illustrative purposes only. Whether you receive a contingent coupon will be determined by reference to the closing level of each underlier on each observation date. The payment at maturity will be determined by reference to the closing level of each underlier on the final observation date. The actual initial level, coupon barrier level and buffer level for each underlier were determined on the strike date. All payments on the securities are subject to our credit risk. The numbers in the hypothetical examples below may have been rounded for ease of analysis. The below examples are based on the following terms:


Stated principal amount:	$1,000 per security
Hypothetical initial level:	With respect to the GDX Fund, $100.00* With respect to the XLK Fund, $100.00*
Contingent coupon:	7.65% per annum (corresponding to approximately $6.375 per interest period per security). The actual contingent coupon will be an amount determined by the calculation agent based on the number of days in the applicable payment period, calculated on a 30/360 day-count basis. The hypothetical contingent coupon of $6.375 is used in these examples for ease of analysis.
Hypothetical coupon barrier level:	With respect to the GDX Fund, $75.00, which is 75% of its hypothetical initial level With respect to the XLK Fund, $75.00, which is 75% of its hypothetical initial level
Hypothetical buffer level:	With respect to the GDX Fund, $70.00, which is 70% of its hypothetical initial level With respect to the XLK Fund, $70.00, which is 70% of its hypothetical initial level
Buffer amount:	30%
Minimum payment at maturity:	30% of the stated principal amount

*The hypothetical initial level of $100.00 for each underlier has been chosen for illustrative purposes only and does not represent the actual initial level of either underlier. Please see “Historical Information” below for historical data regarding the actual closing levels of the underliers.

How to determine whether a contingent coupon is payable with respect to an observation date (if the securities have not been previously redeemed):


	Closing Level			Payment per Security
	GDX Fund	XLK Fund
Hypothetical Observation Date #1	$125.00 (greater than or equal to its coupon barrier level)	$115.00 (greater than or equal to its coupon barrier level)	$6.375
Hypothetical Observation Date #2	$45.00 (less than its coupon barrier level)	$110.00 (greater than or equal to its coupon barrier level)	$0
Hypothetical Observation Date #3	$30.00 (less than its coupon barrier level)	$20.00 (less than its coupon barrier level)	$0

On hypothetical observation date #1, because the closing level of each underlier is greater than or equal to its coupon barrier level, the contingent coupon is paid on the related coupon payment date.

On hypothetical observation date #2, because the closing level of at least one underlier is less than its coupon barrier level, no contingent coupon is paid on the related coupon payment date.

On hypothetical observation date #3, because the closing level of each underlier is less than its coupon barrier level, no contingent coupon is paid on the related coupon payment date.

If the closing level of either underlier is less than its coupon barrier level on each observation date, you will not receive any contingent coupons for the entire term of the securities.

How to calculate the payment at maturity (if the securities have not been redeemed prior to maturity):

The hypothetical examples below illustrate how to calculate the payment at maturity if we do not redeem the securities based on the output of a risk neutral valuation model prior to maturity.


	Final Level			Payment at Maturity per Security
	GDX Fund	XLK Fund
Example #1	$125.00 (greater than or equal to its buffer level)	$115.00 (greater than or equal to its buffer level)	$1,000 + $6.375 (the stated principal amount + the contingent coupon with respect to the final observation date) For more information, please see “How to determine whether a contingent coupon is payable with respect to an observation date (if the securities have not been previously redeemed)” above.
Example #2	$45.00 (less than its buffer level)	$110.00 (greater than or equal to its buffer level)	$1,000 × (performance factor of the worst performing underlier + buffer amount) = $1,000 × [($45.00 / $100.00) + 30%] = $750.00
Example #3	$30.00 (less than its buffer level)	$20.00 (less than its buffer level)	$1,000 × [($20.00 / $100.00) + 30%] = $500.00

In example #1, the final level of each underlier is greater than or equal to its buffer level. Therefore, investors receive at maturity the stated principal amount. Because the final level of each underlier is also greater than or equal to its coupon barrier level, investors receive the contingent coupon with respect to the final observation date. Investors do not participate in any appreciation of either underlier.

In examples #2 and #3, the final level of at least one underlier is less than its buffer level. Therefore, investors receive at maturity a payment that reflects a loss of 1% of principal for each 1% decline in the level of the worst performing underlier beyond the buffer amount. Moreover, because the final level of at least one underlier is also less than its coupon barrier level, investors do not receive a contingent coupon with respect to the final observation date.

If the securities have not been redeemed prior to maturity and the final level of either underlier is less than its buffer level, you will be exposed to the negative performance of the worst performing underlier beyond the buffer amount at maturity, and your payment at maturity will be less, and may be significantly less, than the stated principal amount.

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 and prospectus. We also urge you to consult with your investment, legal, tax, accounting and other advisers in connection with your investment in the securities.

Risks Relating to an Investment in the Securities

￭The securities provide for only the minimum payment at maturity. The terms of the securities differ from those of ordinary debt securities in that they provide for only the minimum payment at maturity. If the securities have not been redeemed prior to maturity and the final level of either underlier is less than its buffer level, the payout at maturity will be an amount in cash that is less than the stated principal amount of each security, and you will lose an amount proportionate to the full decline in the level of the worst performing underlier over the term of the securities beyond the buffer amount. You could lose a significant portion of your initial investment in the securities.

￭The securities do not provide for the regular payment of interest. The terms of the securities differ from those of ordinary debt securities in that they do not provide for the regular payment of interest. Instead, the securities will pay a contingent coupon on a coupon payment date but only if the closing level of each underlier is greater than or equal to its coupon barrier level on the related observation date. However, if the closing level of either underlier is less than its coupon barrier level on any observation date, we will pay no coupon with respect to the applicable interest period. It is possible that the closing level of an underlier will remain below its coupon barrier level for extended periods of time or even throughout the entire term of the securities so that you will receive few or no contingent coupons. If you do not earn sufficient contingent coupons over the term of the securities, the overall return on the securities may be less than the amount that would be paid on a conventional debt security of ours of comparable maturity.

￭Payment of the contingent coupon is based on the closing levels of the underliers on only the related observation date at the end of the related interest period. Whether the contingent coupon will be paid on any coupon payment date will be determined at the end of the related interest period based on the closing level of each underlier on the related observation date. As a result, you will not know whether you will receive the contingent coupon on a coupon payment date until near the end of the relevant interest period. Moreover, because the contingent coupon is based solely on the closing levels of the underliers on the observation dates, if the closing level of either underlier on any observation date is less than its coupon barrier level, you will receive no coupon with respect to the related interest period, even if the closing level of such underlier was greater than or equal to its coupon barrier level on other days during that interest period and even if the closing level of the other underlier is greater than or equal to its coupon barrier level on such observation date.

￭Investors will not participate in any appreciation in the value of either underlier. Investors will not participate in any appreciation in the value of either underlier from the strike date to the final observation date, and the return on the securities will be limited to the contingent coupons that are paid with respect to the observation dates on which the closing level of each underlier is greater than or equal to its coupon barrier level. It is possible that the closing level of an underlier will remain below its coupon barrier level for extended periods of time or even throughout the entire term of the securities so that you will receive few or no contingent coupons.

￭The securities are subject to early redemption risk. The term of your investment in the securities will be shortened if we redeem the securities based on the output of a risk neutral valuation model on any redemption date. In accordance with the risk neutral valuation model determination noted herein, it is more likely that we will redeem the securities when it would be advantageous for you to continue to hold them. As such, we will be more likely to redeem the securities when not redeeming the securities would result in an amount of interest payable on the securities that is greater than instruments of a comparable maturity and credit rating trading in the market. In other words, we will be more likely to redeem the securities at a time when the securities are paying an above-market coupon. If we redeem the securities prior to maturity, you will receive no further payments on the securities, may be forced to invest in a lower interest rate environment and may not be able to reinvest at comparable terms or returns.

On the other hand, we will be less likely to redeem the securities when the closing level of either underlier is less than its coupon barrier level and/or when the final level of either underlier is expected to be less than its buffer level, such that you will receive no contingent coupons and/or suffer a loss on your initial investment in the securities at maturity. Therefore, if we do not redeem the securities prior to maturity, it is more likely that you will receive few or no contingent coupons and suffer a loss at maturity. Under no circumstances will we redeem the securities prior to the first redemption date.

￭The market price of the securities may 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 value of each underlier at any time will affect the value of the securities more than any other single factor. Other factors that may influence the value of the securities include:

othe volatility (frequency and magnitude of changes in value) of the underliers;

Page 8

Morgan Stanley Finance LLC

Callable Contingent Income Buffered Securities

Principal at Risk Securities

ointerest and yield rates in the market;

odividend rates on the underliers;

othe level of correlation between the underliers;

ogeopolitical conditions and economic, financial, political, regulatory or judicial events that affect the underliers or equity markets generally;

othe availability of comparable instruments;

othe occurrence of certain events affecting an underlying fund that may or may not require an adjustment to an adjustment factor;

othe composition of each underlier and changes in the component securities of each underlier;

othe time remaining until the securities mature; and

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

Some or all of these factors will influence the price that you will receive if you sell your securities prior to maturity. 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. For example, you may have to sell your securities at a substantial discount from the stated principal amount if, at the time of sale, the closing level of either underlier is at, below or not sufficiently above its buffer level and/or coupon barrier level, or if market interest rates rise.

You can review the historical closing levels of the underliers in the section of this document called “Historical Information.” You cannot predict the future performance of an underlier based on its historical performance. The values of the underliers may be, and have recently been, volatile, and we can give you no assurance that the volatility will lessen. There can be no assurance that the closing level of each underlier will be greater than or equal to its coupon barrier level on any observation date so that you will receive a contingent coupon with respect to the applicable interest period, or that the final level of each underlier will be greater than or equal to its buffer level so that you do not suffer a loss on your initial investment in the securities.

￭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, and, therefore, you are subject to our credit risk. The securities are not guaranteed by any other entity. If we default on our obligations under the securities, your investment would be at risk and you could lose 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.

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

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

However, because the costs associated with issuing, selling, structuring and hedging the securities are not fully deducted upon issuance, to the extent that MS & Co. may buy or sell the securities in the secondary market during the amortization period specified herein, absent changes in market conditions, including those related to the underliers, and to our secondary market credit spreads, it would do so based on values higher than the estimated value, and we expect that those higher values will also be reflected in your brokerage account statements.

￭The estimated value of the securities is determined by reference to our pricing and valuation models, which may differ from those of other dealers and is not a maximum or minimum secondary market price. These pricing and valuation models are proprietary and rely in part on subjective views of certain market inputs and certain assumptions about future events, which may prove to be incorrect. As a result, because there is no market-standard way to value these types of securities, our models may yield a higher estimated value of the securities than those generated by others, including other dealers in the market, if they attempted to value the securities. In addition, the estimated value on the pricing date does not represent a minimum or maximum price at which dealers, including MS & Co., would be willing to purchase your securities in the secondary market (if any exists) at any time. The value of your securities at any time after the date of this document will vary based on many factors that cannot be predicted with accuracy, including our creditworthiness and changes in market conditions. See also “The market price of the securities may 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. may, but is not obligated to, make a market in the securities and, if it once chooses to make a market, may cease doing so at any time. When it does make a market, it will generally do so for transactions of routine secondary market size at prices based on its estimate of the current value of the securities, taking into account its bid/offer spread, our credit spreads, market volatility, the notional size of the proposed sale, the cost of unwinding any related hedging positions, the time remaining to maturity and the likelihood that it will be able to resell the securities. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the securities easily. Since other broker-dealers may not participate significantly in the secondary market for the securities, the price at which you may be able to trade your securities is likely to depend on the price, if any, at which MS & Co. is willing to transact. If, at any time, MS & Co. were to cease making a market in the securities, it is likely that there would be no secondary market for the securities. Accordingly, you should be willing to hold your securities to maturity.

￭As discussed in more detail in the accompanying product supplement, investing in the securities is not equivalent to investing in the underlier(s).

￭The U.S. federal income tax consequences of an investment in the securities are uncertain. There is no direct legal authority regarding the proper U.S. federal income tax treatment of the securities, and significant aspects of the tax treatment of the securities are uncertain. Moreover, non-U.S. investors should note that persons having withholding responsibility in respect of the securities are, absent an exception, expected to withhold on any coupon paid to a non-U.S. investor, generally at a rate of 30%. We will not pay any additional amounts in respect of such withholding. You should review carefully the section entitled “United States Federal Income Tax Considerations” herein, in combination with the section entitled “United States Federal Income Tax Considerations” in the accompanying product supplement, and consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the securities.

Risks Relating to the Underlier(s)

￭Because your return on the securities will depend upon the performance of the underlier(s), the securities are subject to the following risk(s), as discussed in more detail in the accompanying product supplement.

oYou are exposed to the price risk of each underlier.

oBecause the securities are linked to the performance of the worst performing underlier, you are exposed to a greater risk of not receiving a positive return on the securities and/or sustaining a loss on your investment than if the securities were linked to just one underlier.

oThere are risks associated with investments in securities linked to the value of foreign equity securities.

oSecurities linked to certain underliers are subject to currency exchange risk.

oAdjustments to an underlying fund or the index tracked by such underlying fund could adversely affect the value of the securities.

oThe performance and market price of an underlying fund, particularly during periods of market volatility, may not correlate with the performance of its share underlying index, the performance of the component securities of its share underlying index or the net asset value per share of such underlying fund.

oThe anti-dilution adjustments the calculation agent is required to make do not cover every event that could affect an underlying fund.

￭The securities are subject to risks associated with the gold and silver mining industry. Because the securities are linked to the VanEck® Gold Miners ETF, the securities are subject to certain risks applicable to the gold and silver mining industry. The stocks included in the NYSE Arca Gold Miners Index and that are generally tracked by the VanEck® Gold Miners ETF are stocks of companies primarily engaged in the mining of gold or silver. The VanEck® Gold Miners ETF may be subject to increased price volatility as it is linked to a single industry, market or sector, and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that industry, market or sector.

Because the VanEck® Gold Miners ETF primarily invests in stocks, American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”) of companies that are involved in the gold mining industry, the VanEck® Gold Miners ETF is subject to certain risks associated with such companies.

Competitive pressures may have a significant effect on the financial condition of companies in the gold mining industry. Also, gold mining companies are highly dependent on the price of gold. Gold prices are subject to volatile price movements over short periods of time and are affected by numerous factors. These include economic factors, including, among other things, the structure of and confidence in the global monetary system, expectations of the future rate of inflation, the relative strength of, and confidence in, the U.S. dollar (the currency in which the price of gold is generally quoted), interest rates and gold borrowing and lending rates, and global or regional economic, financial, political, regulatory, judicial or other events. Gold prices may also be affected by industry factors such as industrial and jewelry demand, lending, sales and purchases of gold by the official sector, including central banks and other governmental agencies and multilateral institutions which hold gold, levels of gold production and production costs, and short-term changes in supply and demand because of trading activities in the gold market.

The VanEck® Gold Miners ETF invests to a lesser extent in stocks, ADRs and GDRs of companies involved in the silver mining industry. Silver mining companies are highly dependent on the price of silver. Silver prices can fluctuate widely and may be affected by numerous factors. These include general economic trends, technical developments, substitution issues and regulation, as well as specific factors including industrial and jewelry demand, expectations with respect to the rate of inflation, the relative strength of the U.S. dollar (the currency in which the price of silver is generally quoted) and other currencies, interest rates, central bank sales, forward sales by producers, global or regional political or economic events, and production costs and disruptions in major silver producing countries. The supply of silver consists of a combination of new mine production and existing stocks of bullion and fabricated silver held by governments, public and private financial institutions, industrial organizations and private individuals. In addition, the price of silver has on occasion been subject to very rapid short-term changes due to speculative activities. From time to time, above-ground inventories of silver may also influence the market. The major end-uses for silver include industrial applications, jewelry, photography and silverware.

￭The securities are subject to risks associated with investments in securities with a concentration in the technology sector. The securities included in the Technology Select Sector Index and that are generally tracked by the Technology Select Sector SPDR® Fund are securities of companies whose primary business is directly associated with the technology sector, including the following sub-sectors: computers and peripherals, software, diversified telecommunication services, communications equipment, semiconductors and semiconductor equipment, internet software and services, IT services, electronic equipment, instruments and components, wireless telecommunication services and office electronics.

The values of stocks of technology companies and companies that rely heavily on technology are particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Additionally, companies in the technology sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel. All of these factors could have an effect on the level of the Technology Select Sector SPDR® Fund and, therefore, on the value of the securities.

Risks Relating to Conflicts of Interest

In engaging in certain activities described below and as discussed in more detail in the accompanying product supplement, our affiliates may take actions that may adversely affect the value of and your return on the securities, and in so doing they will have no obligation to consider your interests as an investor in the securities.

￭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 make any determinations necessary to calculate any payment(s) on the securities. Moreover, certain determinations made by MS & Co., in its capacity as calculation agent, may require it to exercise discretion and make subjective judgments, which may adversely affect your return on the 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.

Additional Information About the Securities


Additional Information:
Minimum ticketing size:	$1,000 / 1 security
United States federal income tax considerations:	You should review carefully the section in the accompanying product supplement entitled “United States Federal Income Tax Considerations.” The following discussion, when read in combination with that section, constitutes the full opinion of our counsel, Davis Polk & Wardwell LLP, regarding the material U.S. federal income tax consequences of owning and disposing of the securities. Generally, this discussion assumes that you purchased the securities for cash in the original issuance at the stated issue price and does not address other circumstances specific to you, including consequences that may arise due to any other investments relating to an underlier. You should consult your tax adviser regarding the effect any such circumstances may have on the U.S. federal income tax consequences of your ownership of a security. In the opinion of our counsel, which is based on current market conditions, it is reasonable to treat the securities for U.S. federal income tax purposes as prepaid financial contracts with associated coupons, and any coupons as ordinary income, as described in the section entitled “United States Federal Income Tax Considerations—Tax Consequences to U.S. Holders—Securities Treated as Prepaid Financial Contracts with Associated Coupons” in the accompanying product supplement. There is uncertainty regarding this treatment, and the IRS or a court might not agree with it. A different tax treatment could be adverse to you. We do not plan to request a ruling from 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 particular, there is a risk that the securities could be characterized as debt instruments for U.S. federal income tax purposes, in which case the tax consequences of an investment in the securities could be different from those described herein and possibly adverse to certain investors. 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. Non-U.S. Holders. The U.S. federal income tax treatment of the coupons is unclear. To the extent that we have withholding responsibility in respect of the securities, we would expect generally to treat the coupons paid to Non-U.S. Holders (as defined in the accompanying product supplement) as subject to U.S. withholding tax. Moreover, you should expect that, if the applicable withholding agent determines that withholding tax should apply, it will be at a rate of 30% (or lower treaty rate). In order to claim an exemption from, or a reduction in, the 30% withholding under an applicable treaty, you may need to comply with certification requirements to establish that you are not a U.S. person and are eligible for such an exemption or reduction under an applicable tax treaty. You should consult your tax adviser regarding the tax treatment of the coupons. As discussed under “United States Federal Income Tax Considerations—Tax Consequences to Non-U.S. Holders—Dividend Equivalents under Section 871(m) of the Code” in the accompanying product supplement, Section 871(m) of the Internal Revenue Code and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% 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. The Treasury regulations, as modified by an IRS notice, exempt financial instruments issued prior to January 1, 2027 that do not have a “delta” of one. Based on certain representations made by us, our counsel is of the opinion that Section 871(m) should not apply to the securities with regard to Non-U.S. Holders. Our determination is not binding on the IRS, and the IRS may disagree with this determination. We will not be required to pay any additional amounts with respect to U.S. federal withholding taxes. You should consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments, as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.
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.
