Fully and Unconditionally Guaranteed by Morgan Stanley

Principal at Risk Securities

The securities offered are unsecured obligations of Morgan Stanley Finance LLC (“MSFL”) and are fully and unconditionally guaranteed by Morgan Stanley. The securities do not guarantee the repayment of principal, do not provide for the regular payment of interest and have the terms described in the accompanying product supplement and prospectus, as supplemented or modified by this document. The securities will be automatically redeemed if the determination closing price on the first determination date is greater than or equal to the initial share price, for an early redemption payment of at least $1,150.00 per security‬ (to be determined on the pricing date), as described below. No further payments will be made on the securities once they have been redeemed. At maturity, if the securities have not previously been redeemed and the final share price is greater than the initial share price, investors will receive the stated principal amount of their investment plus a return reflecting 185% of the upside performance of the underlying shares. If the securities are not automatically redeemed prior to maturity and the final share price is less than or equal to the initial share price but greater than or equal to 70‬% of the initial share price, which we refer to as the downside threshold level, investors will receive the stated principal amount of their investment. However, if the securities are not automatically redeemed prior to maturity and the final share price is less than the downside threshold level, investors will be exposed to the decline in the underlying shares on a 1-to-1 basis and will receive a payment at maturity that is less than 70‬% of the stated principal amount of the securities and could be zero. Accordingly, investors in the securities must be willing to accept the risk of losing their entire initial investment. The securities are for investors who are willing to risk their principal and forego current income in exchange for the possibility of receiving an early redemption payment or a payment at maturity greater than the stated principal amount if the underlying shares close at or above the initial share price on the first determination date or above the initial share price on the final determination date, respectively, and the limited protection against loss that applies only if the final share price is greater than or equal to the downside threshold level. 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.

Jump Securities with Auto-Callable Feature Based on the Performance of the iShares® MSCI Brazil ETF due April 1, 2027

Principal at Risk Securities

The original issue price of each security is $1,000. This price includes costs associated with issuing, selling, structuring and hedging the securities, which are borne by you, and, consequently, the estimated value of the securities on the pricing date will be less than $1,000. We estimate that the value of each security on the pricing date will be approximately $939.60, or within $30.00 of that estimate. Our estimate of the value of the securities as determined on the pricing date will be set forth in the final pricing supplement.

What goes into the estimated value on the pricing date?

In valuing the securities on the pricing date, we take into account that the securities comprise both a debt component and a performance-based component linked to the underlying shares. The estimated value of the securities 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 securities?

In determining the economic terms of the securities, including the early redemption payment amount and the downside threshold level, we use an internal funding rate, which is likely to be lower than our secondary market credit spreads and therefore advantageous to us. If the issuing, selling, structuring and hedging costs borne by you were lower or if the internal funding rate were higher, one or more of the economic terms of the securities would be more favorable to you.

What is the relationship between the estimated value on the pricing date and the secondary market price of the securities?

The price at which MS & Co. purchases the securities in the secondary market, absent changes in market conditions, including those related to the underlying 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 securities are not fully deducted upon issuance, for a period of up to 6 months following the issue date, to the extent that MS & Co. may buy or sell the securities in the secondary market, absent changes in market conditions, including those related to the underlying 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 securities and, if it once chooses to make a market, may cease doing so at any time.

Key Investment Rationale

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

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

Scenario 1: The securities are redeemed prior to maturity	If the underlying shares close at or above the initial share price on the first determination date, the securities will be automatically redeemed for the early redemption payment on the early redemption date. Investors do not participate in any appreciation of the underlying shares.
Scenario 2: The securities are not redeemed prior to maturity, and investors receive a positive return at maturity	This scenario assumes that the underlying shares close below the initial share price on the first determination date. Consequently, the securities are not redeemed prior to maturity. On the final determination date, the underlying shares close above the initial share price. At maturity, investors will receive the stated principal amount of their investment plus a return reflecting 185% of the upside performance of the underlying shares.
Scenario 3: The securities are not redeemed prior to maturity, and investors receive the stated principal amount at maturity	This scenario assumes that the underlying shares close below the initial share price on the first determination date. Consequently, the securities are not redeemed prior to maturity. On the final determination date, the underlying shares close at or below the initial share price but at or above the downside threshold level of 70‬% of the initial share price. At maturity, investors will receive a cash payment equal to the stated principal amount of $1,000.
Scenario 4: The securities are not redeemed prior to maturity, and investors suffer a significant loss of principal at maturity	This scenario assumes that the underlying shares close below the initial share price on the first determination date. Consequently, the securities are not redeemed prior to maturity. On the final determination date, the underlying shares close below the downside threshold level. At maturity, investors will receive an amount equal to the stated principal amount multiplied by the share performance factor. Under these circumstances, the payment at maturity will be significantly less than the stated principal amount and could be zero.

Hypothetical Examples

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

Hypothetical Initial Share Price:	$40.00
Hypothetical Downside Threshold Level:	$28.00, which is 70‬% of the hypothetical initial share price
Hypothetical Early Redemption Payment:	The hypothetical early redemption payment will be an amount in cash per stated principal amount, as follows: ●1st determination date:    $1,150‬.00‬ No further payments will be made on the securities once they have been redeemed.
Payment at Maturity:	If the securities have not previously been redeemed, you will receive at maturity a cash payment per security as follows: ●If the final share price is greater than the initial share price: $1,000 + ($1,000 × share percent change × 185%) ●If the final share price is less thanor equal to the initial share price but greater than or equal to the downside threshold level: $1,000 ●If the final share price is less than the downside threshold level: $1,000 × share performance factor Under these circumstances, you will lose a significant portion or all of your investment.
Stated Principal Amount:	$1,000
Adjustment Factor:	1.0

Automatic Call:

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

Date	Determination Closing Price	Payment (per Security)
1st Determination Date	$80.00 (at or above the initial share price, securities are automatically redeemed)	$1,150‬.00‬

In this example, the determination closing price on the first determination date is at or above the initial share price. Therefore the securities are automatically redeemed on the early redemption date. Investors will receive a payment of $1,150‬.00‬ per security on the early redemption date. No further payments will be made on the securities once they have been redeemed, and investors do not participate in the appreciation of the underlying shares.

Payment at Maturity

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

Example 1 — the final share price is above the initial share price

Date	Determination Closing Price	Payment (per Security)
1st Determination Date	$35.00 (below the initial share price, securities are not redeemed)	--
Final Determination Date	$44.00 (above the initial share price)	$1,000 + ($1,000 × 10% × 185%) = $1,185

In this example, the determination closing price is below the initial share price on the first determination date, and therefore the securities are not redeemed prior to maturity. On the final determination date, the underlying shares have appreciated 10% from the hypothetical initial share price. At maturity, investors receive the stated principal amount plus a return reflecting 185% of the appreciation of the underlying shares. Investors receive $1,185.00 per security at maturity.

Example 2 — the final share price is at or below the initial share price but at or above the downside threshold level

Date	Determination Closing Price	Payment (per Security)
1st Determination Date	$30.00 (below the initial share price, securities are not redeemed)	--
Final Determination Date	$32.00 (at or below the initial share price but at or above the downside threshold level)	$1,000

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

Example 3 — the final share price is below the downside threshold level

Date	Determination Closing Price	Payment (per Security)
1st Determination Date	$25.00 (below the initial share price, securities are not redeemed)	--

Final Determination Date $12.00 (below the downside threshold level) $1,000 × share performance factor = $1,000 × 30% = $300

In this example, the determination closing price is below the initial share price on the first determination date, and therefore the securities are not redeemed prior to maturity. On the final determination date, the final share price is below the downside threshold level, and accordingly, investors are fully exposed to the negative performance of the underlying shares over the term of the securities, and will receive a payment at maturity that is significantly less than the stated principal amount of the securities. The payment at maturity is $300 per security, representing a loss of 30% on your investment.

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

Risk Factors

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

Risks Relating to an Investment in the Securities

￭The securities do not pay interest or guarantee the return of any principal. The terms of the securities differ from those of ordinary debt securities in that they do not pay interest or guarantee the return of any of the principal amount at maturity. If the securities have not been automatically redeemed prior to maturity and if the final share price is less than the downside threshold level, you will be exposed to the decline in the closing price of the underlying shares, as compared to the initial share price, on a 1-to-1 basis, and you will receive for each security that you hold at maturity an amount equal to the stated principal amount times the share performance factor. In this case, the payment at maturity will be less than 70‬% of the stated principal amount and could be zero.

￭If the securities are redeemed prior to maturity, the appreciation potential of the securities is limited by the fixed early redemption payment specified for the first determination date. If the underlying shares close at or above the initial share price on the first determination date, the securities will be automatically redeemed. In this scenario, the appreciation potential of the securities is limited to the fixed early redemption payment specified for the first determination date, and no further payments will be made on the securities once they have been redeemed. In addition, if the securities are redeemed prior to maturity, you will not participate in any appreciation of the underlying shares, which could be significant. Moreover, the fixed early redemption payment may be less than the payment at maturity you would receive for the same level of appreciation of the underlying shares had the securities not been automatically redeemed and instead remained outstanding until maturity.

￭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 closing price of the underlying shares on any day will affect the value of the securities more than any other factors. Other factors that may influence the value of the securities include:

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

ointerest and yield rates in the market,

othe time remaining until the securities mature,

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

othe occurrence of certain events affecting the underlying shares 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. You cannot predict the future performance of the iShares‬‬® MSCI Brazil‬ ETF based on its historical performance. There can be no assurance that the closing value of the underlying shares will be at or above the initial share price on the first determination date or at or above the downside threshold level on the final determination date so that you do not suffer a significant loss on your initial investment in the securities. See “iShares‬‬® MSCI Brazil‬ ETF Overview” below.

Principal at Risk Securities

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 “iShares‬‬® MSCI Brazil‬ ETF Overview” below. You may receive less, and possibly significantly less, than the stated principal amount per security if you try to sell your securities prior to maturity.

￭The securities are subject to our credit risk, and any actual or anticipated changes to our credit ratings or credit spreads may adversely affect the market value of the securities. You are dependent on our ability to pay all amounts due on the securities upon an early redemption or at maturity and therefore you are subject to our credit risk. If we default on our obligations under the securities, your investment would be at risk and you could lose some or all of your investment. As a result, the market value of the securities prior to maturity will be affected by changes in the market’s view of our creditworthiness. Any actual or anticipated decline in our credit ratings or increase in the credit spreads charged by the market for taking our credit risk is likely to adversely affect the market value of the securities.

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

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

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

￭Not equivalent to investing in the underlying shares. Investing in the securities is not equivalent to investing in the underlying shares. Investors in the securities will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the underlying shares.

￭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,

Principal at Risk Securities

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, for a period of up to 6 months following the issue date, to the extent that MS & Co. may buy or sell the securities in the secondary market, absent changes in market conditions, including those related to the underlying 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 securities is determined by reference to our pricing and valuation models, which may differ from those of other dealers and is not a maximum or minimum secondary market price. These pricing and valuation models are proprietary and rely in part on subjective views of certain market inputs and certain assumptions about future events, which may prove to be incorrect. As a result, because there is no market-standard way to value these types of securities, our models may yield a higher estimated value of the securities than those generated by others, including other dealers in the market, if they attempted to value the securities. In addition, the estimated value on the pricing date does not represent a minimum or maximum price at which dealers, including MS & Co., would be willing to purchase your securities in the secondary market (if any exists) at any time. The value of your securities at any time after the date of this document will vary based on many factors that cannot be predicted with accuracy, including our creditworthiness and changes in market conditions. See also “The market price will be influenced by many unpredictable factors” above.

￭Hedging and trading activity by our affiliates could potentially affect the value of the securities. One or more of our affiliates and/or third-party dealers expect to carry out hedging activities related to the securities (and to other instruments linked to the underlying shares), including trading in the underlying shares as well as in other instruments related to the underlying shares. As a result, these entities may be unwinding or adjusting hedge positions during the term of the securities, and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the final determination date approaches. Some of our affiliates also trade the underlying shares and/or other financial instruments related to the underlying shares 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 (i) the price at or above which the underlying shares must close on the first determination date so that the securities are redeemed prior to maturity for the early redemption payment, and (ii) the downside threshold level, which is the price at or above which the underlying shares must close on the final determination date so that you are not exposed to the negative price performance of the underlying shares at maturity. Additionally, such hedging or trading activities during the term of the securities could potentially affect the price of the underlying shares on the determination dates, and, accordingly, whether we redeem the securities prior to maturity and the amount of cash you will receive at maturity, if any.

￭The calculation agent, which is a subsidiary of Morgan Stanley and an affiliate of MSFL, will make determinations with respect to the securities. As calculation agent, MS & Co. will determine the initial share price, the downside threshold level, whether the securities will be redeemed on the early redemption date, the final share price, whether to make any adjustments to the adjustment factor and the payment you will receive at maturity, if any. Moreover, certain determinations made by MS & Co., in its capacity as calculation agent, may require it to exercise discretion and make subjective judgments, such as with respect to the occurrence or non-occurrence of market disruption events and certain adjustments to the adjustment factor, may adversely affect the payout to you at maturity, if any. For further information regarding these types of determinations, see "Description of Auto-Callable Securities—Postponement of Determination Dates," "—Alternate Exchange Calculation in Case of an Event of Default” and "—Calculation Agent and Calculations" in the accompanying product supplement and “Additional Terms of the Securities—

￭The U.S. federal income tax consequences of an investment in the securities are uncertain. Please read the discussion under “Additional Information—Tax considerations” in this document and the discussion under “United States Federal Taxation” in the accompanying product supplement for auto-callable securities(together, the “Tax Disclosure Sections”) concerning the U.S. federal income tax consequences of an investment in the securities. 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 for the securities, the timing and character of income on the securities 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 securities as debt instruments. In that event, U.S. Holders would be required to accrue into income original issue discount on the securities every year at a “comparable yield” determined at the time of issuance and recognize all income and gain in respect of the securities as ordinary income. The risk that financial instruments providing for buffers, triggers or similar downside protection features, such as the securities, 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 securities, 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 securities, 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 securities, 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

￭There are risks associated with investments in securities linked to the value of foreign (and especially emerging markets) equity securities. The price of the Fund tracks the performance of the Brazil 25/50 Index (the “share underlying index”), which is linked to the value of foreign (and especially emerging markets) equity securities. Investments in securities linked to the value of foreign equity securities involve risks associated with the securities markets in those countries, including risks of volatility in those markets, governmental intervention in those markets and cross-shareholdings in companies in certain countries. Also, there is generally less publicly available information about foreign companies than about U.S. companies that are subject to the reporting requirements of the Securities and Exchange Commission, and foreign companies are subject to accounting, auditing and financial reporting standards and requirements different from those applicable to U.S. reporting companies. The prices of securities issued in foreign markets may be affected by political, economic, financial and social factors in those countries, or global regions, including changes in government, economic and fiscal policies and currency exchange laws. In addition, the stocks included in the Brazil 25/50 Index and that are generally tracked by the underlying shares have been issued by companies in various emerging markets countries, which pose further risks in addition to the risks associated with investing in foreign equity markets generally. Countries with emerging markets may have relatively unstable

March 2024Page 12

Jump Securities with Auto-Callable Feature Based on the Performance of the iShares® MSCI Brazil ETF due April 1, 2027

Principal at Risk Securities

governments, may present the risks of nationalization of businesses, restrictions on foreign ownership and prohibitions on the repatriation of assets, and may have less protection of property rights than more developed countries. The economies of countries with emerging markets may be based on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates. Local securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times. Moreover, the economies in such countries may differ unfavorably from the economy in the United States in such respects as growth of gross national product, rate of inflation, capital reinvestment, resources, self-sufficiency and balance of payment positions between countries.

￭Adjustments to the underlying shares or to the Brazil 25/50 Index could adversely affect the value of the securities. The investment advisor to the Fund, BlackRock Fund Advisors (the “Investment Advisor”), seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the Brazil 25/50 Index. Pursuant to its investment strategy or otherwise, the Investment Advisor 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 securities. MSCI Inc. (“MSCI”) is responsible for calculating and maintaining the Brazil 25/50 Index. MSCI may add, delete or substitute the stocks constituting the Brazil 25/50 Index or make other methodological changes that could change the level of the Brazil 25/50 Index. MSCI may discontinue or suspend calculation or publication of the Brazil 25/50 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 Brazil 25/50 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 securities.

￭The securities are subject to currency exchange risk. Because the price of the underlying shares tracks the performance of the Brazil 25/50 Index, holders of the securities will be exposed to currency exchange rate risk with respect to each of the currencies in which such component securities trade. Exchange rate movements for a particular currency are volatile and are the result of numerous factors including the supply of, and the demand for, those currencies, as well as relevant government policy, intervention or actions, but are also influenced significantly from time to time by political or economic developments, and by macroeconomic factors and speculative actions related to the relevant region. An investor’s net exposure will depend on the extent to which the currencies of the component securities strengthen or weaken against the U.S. dollar and the relative weight of each currency. If, taking into account such weighting, the dollar strengthens against the currencies of the component securities represented in the Brazil 25/50 Index, the price of the underlying shares will be adversely affected and the payment at maturity on the securities may be reduced.

Of particular importance to potential currency exchange risk are:

oexisting and expected rates of inflation;

oexisting and expected interest rate levels;

othe balance of payments between countries; and

othe extent of governmental surpluses or deficits in the relevant countries and the United States.

All of these factors are in turn sensitive to the monetary, fiscal and trade policies pursued by the governments of various countries represented in the Brazil 25/50 Index and the United States and other countries important to international trade and finance.

￭The performance and market price of the Fund, particularly during periods of market volatility, may not correlate with the performance of the Brazil 25/50 Index, the performance of the component securities of the Brazil 25/50 Index or the net asset value per share of the Fund. The Fund does not fully replicate the Brazil 25/50 Index and may hold securities that are different than those included in the Brazil 25/50 Index. In addition, the performance of the Fund will reflect additional transaction costs and fees that are not included in the calculation of the Brazil 25/50 Index. All of these factors may lead to a lack of correlation between the performance of the Fund and the Brazil 25/50 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 Brazil 25/50 Index.

Principal at Risk Securities

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 Brazil 25/50 Index.

For all of the foregoing reasons, the performance of the Fund may not correlate with the performance of the Brazil 25/50 Index, the performance of the component securities of the Brazil 25/50 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 securities. 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 securities. 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 Brazil 25/50 Index or the component securities of the Brazil 25/50 Index and/or trading below the net asset value per share of the Fund.

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

Discontinuance of the underlying shares; alteration of method of calculation:	The following replaces in its entirety the section entitled “Discontinuance of the Underlying Shares of an Exchange-Traded Fund and/or Share Underlying Index; Alteration of Method of Calculation” in the accompanying product supplement for auto-callable securities: If trading in the underlying shares on every applicable national securities exchange, on the OTC Bulletin Board and in the over-the-counter market is permanently discontinued or the Fund is liquidated or otherwise terminated (a “discontinuance or liquidation event”), the calculation agent will, in its discretion, either (i) substitute an exchange-traded fund that the calculation agent determines, in its sole discretion, to be comparable to the discontinued Fund (the “successor fund”), after which any subsequent closing price for the underlying shares on any trading day following a discontinuance or liquidation event will be determined by reference to the published price of such successor fund at the regular weekday close of trading on such trading day, or (ii) accelerate the securities on the fifth business day following the date notice of such liquidation event is provided to holders of the underlying shares (the date of such notice, the “liquidation announcement date,” and the fifth business day following the liquidation announcement date, the “acceleration date”), after which the payment to you on the acceleration date will be equal to the fair market value of the securities on the trading day immediately following the liquidation announcement date, as determined by the calculation agent in its sole discretion based on its internal models, which will take into account the reasonable costs incurred by us or any of our affiliates in unwinding any related hedging arrangements. Upon any selection by the calculation agent of a successor fund, the calculation agent will cause written notice thereof to be furnished to the trustee, to us and to the depositary, as holder of the securities, within three business days of such selection. We expect that such notice will be made available to you, as a beneficial owner of the securities, in accordance with the standard rules and procedures of the depositary and its direct and indirect participants.
Trustee:	The Bank of New York Mellon
Calculation agent:	MS & Co.
Issuer notice to registered security holders, the trustee and the depositary:	In the event that the maturity date is postponed due to postponement of the final determination date, the issuer shall give notice of such postponement and, once it has been determined, of the date to which the maturity date has been rescheduled (i) to each registered holder of the securities by mailing notice of such postponement by first class mail, postage prepaid, to such registered holder’s last address as it shall appear upon the registry books, (ii) to the trustee by facsimile, confirmed by mailing such notice to the trustee by first class mail, postage prepaid, at its New York office and (iii) to The Depository Trust Company (the “depositary”) by telephone or facsimile confirmed by mailing such notice to the depositary by first class mail, postage prepaid. Any notice that is mailed to a registered holder of the securities in the manner herein provided shall be conclusively presumed to have been duly given to such registered holder, whether or not such registered holder receives the notice. The issuer shall give such notice as promptly as possible, and in no case later than (i) with respect to notice of postponement of the maturity date, the business day immediately preceding the scheduled maturity date and (ii) with respect to notice of the date to which the maturity date has been rescheduled, the business day immediately following the final determination date as postponed. In the event that the securities are subject to early redemption, the issuer shall, (i) on the business day following the applicable determination date, give notice of the early redemption and the early redemption payment, including specifying the payment date of the amount due upon the early redemption, (x) to each registered holder of the securities by mailing notice of such early redemption by first class mail, postage prepaid, to such registered holder’s last address as it shall appear upon the registry books, (y) to the trustee by facsimile confirmed by mailing such notice to the trustee by first class mail, postage prepaid, at its New York office and (z) to the depositary by telephone or facsimile confirmed by mailing such notice to the depositary by first class mail, postage prepaid and (ii) on or prior to the early redemption date, deliver the aggregate cash amount due with respect to the securities to the trustee for delivery to the depositary, as holder of the securities. Any notice that is mailed to a registered holder of the securities in the manner herein provided shall be conclusively presumed to have been duly given to such registered holder, whether or not such registered holder receives the notice. This notice shall be given by the issuer or, at the issuer’s request, by the trustee in the name and at the expense of the issuer, with any such request to be accompanied by a copy of the notice to be given.

Additional Information About the Securities

Additional Information:
Minimum ticketing size:	$1,000 / 1 security
Tax considerations:	Although there is uncertainty regarding the U.S. federal income tax consequences of an investment in the securities due to the lack of governing authority, in the opinion of our counsel, Davis Polk & Wardwell LLP, under current law, and based on current market conditions, a security should be treated as a single financial contract that is an “open transaction” for U.S. federal income tax purposes. However, because our counsel’s opinion is based in part on market conditions as of the date of this document, it is subject to confirmation on the pricing date. Assuming this treatment of the securities is respected and subject to the discussion in “United States Federal Taxation” in the accompanying product supplement for auto-callable securities, the following U.S. federal income tax consequences should result based on current law: ￭A U.S. Holder should not be required to recognize taxable income over the term of the securities prior to settlement, other than pursuant to a sale or exchange. ￭Upon sale, exchange or settlement of the securities, a U.S. Holder should recognize gain or loss equal to the difference between the amount realized and the U.S. Holder’s tax basis in the securities. 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 substantial 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). As a result of certain features of the securities, including the leveraged upside payment, it is unclear how to calculate the amount of gain that would be recharacterized if an investment in the securities 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 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 auto-callable securities 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 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 securities, possibly with retroactive effect. As discussed in the accompanying product supplement for auto-callable 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, 2025 that do not have a delta of one with respect to any Underlying Security. Based on the terms of the securities and current market conditions, we expect that the securities will not have a delta of one with respect to any Underlying Security on the pricing date. However, we will provide an updated determination in the pricing supplement. Assuming that the securities do not have a delta of one with respect to any Underlying Security, our counsel is of the opinion that the securities should not be Specified Securities and, therefore, should not be subject to Section 871(m). Our determination is not binding on the IRS, and the IRS may disagree with this determination. Section 871(m) is complex and its application may depend on your particular circumstances, including whether you enter into other transactions with respect to an Underlying Security. If withholding is required, we will not be required to pay any additional amounts with respect to the amounts so withheld. You should consult your tax adviser regarding the potential application of Section 871(m) to the securities. Both U.S. and non-U.S. investors considering an investment in the securities should read the discussion under “Risk Factors” in this document and the discussion under “United States Federal Taxation” in the accompanying product supplement for auto-callable securities and consult their tax advisers regarding all aspects of the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments, 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 auto-callable securities, insofar as they purport to describe provisions of U.S. federal income tax laws or legal conclusions with respect thereto, constitute the full opinion of Davis Polk & Wardwell LLP regarding the material U.S. federal tax consequences of an investment in the securities.

Use of proceeds and hedging:

The proceeds from the sale of the securities will be used by us for general corporate purposes. We will receive, in aggregate, $1,000 per security issued, because, when we enter into hedging transactions in order to meet our obligations under the securities, our hedging counterparty will reimburse the cost of the agent’s commissions. The costs of the securities borne by you and described beginning on page 4 above comprise the agent’s commissions and the cost of issuing, structuring and hedging the securities. On or prior to the pricing date, we will hedge our anticipated exposure in connection with the securities by entering into hedging transactions with our affiliates and/or third-party dealers. We expect our hedging counterparties to take positions in the underlying shares, in futures and/or options contracts on the underlying shares, or positions in any other available securities or instruments that they may wish to use in connection with such hedging. Such purchase activity could potentially increase the initial share price, and, therefore, could increase (i) the price at or above which the underlying shares must close on the determination dates so that the securities are redeemed prior to maturity for the early redemption payment, and (ii) the downside threshold level, which is the price at or above which the underlying shares must close on the final determination date so that you are not exposed to the negative price performance of the underlying shares at maturity. In addition, through our affiliates, we are likely to modify our hedge position throughout the term of the securities, including on the determination dates, by purchasing and selling the underlying shares, options contracts relating to the underlying shares or any other available securities or instruments that we may wish to use in connection with such hedging activities. As a result, these entities may be unwinding or adjusting hedge positions during the term of the securities, and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the final determination date approaches. Additionally, our hedging activities, as well as our other trading activities, during the term of the securities could potentially affect the price of the

	underlying shares on the determination dates, and, accordingly, whether we redeem the securities prior to maturity and the amount of cash you will receive at maturity, if any.
