Buffered Performance Leveraged Upside SecuritiesSM (Buffered PLUSSM) due August 5, 2025

$● Based on the Performance of the S&P 500® Index

Principal at Risk Securities

The Buffered Performance Leveraged Upside SecuritiesSM (the “Buffered PLUS”) offer leveraged exposure to the performance of the S&P 500® Index (the “underlying index”). The Buffered PLUS are for investors who are willing to risk their principal and forgo current income and upside above the maximum payment at maturity in exchange for the leverage feature which applies to a limited range of positive performance of the underlying index. The amount that investors receive at maturity for each Buffered PLUS, will be based on the direction and percentage change in the level of the underlying index from the pricing date to the valuation date (the “underlying return”) and whether the percentage decline of the underlying index from the closing level of the underlying index on the pricing date (the “initial level”) to the closing level of the underlying index on the valuation date (the “final level”) is greater than the buffer amount. At maturity, if the underlying index has appreciated, investors will receive the stated principal amount of their investment plus the leveraged upside performance of the underlying index, subject to the maximum payment at maturity. At maturity, if the underlying index has depreciated and the percentage decline from the initial level to the final level is equal to or less than the buffer amount, the investor will receive the stated principal amount. However, if the underlying index has depreciated and the percentage decline from the initial level to the final level is greater than the buffer amount, investors will receive less than the stated principal amount, resulting in a loss that is proportionate to the percentage decline in the underlying index from the initial level to the final level in excess of the buffer amount. Investors may lose up to 90% of the stated principal amount of the Buffered PLUS. Accordingly, the Buffered PLUS do not guarantee the return of the full principal amount at maturity. The Buffered PLUS are unsubordinated, unsecured debt obligations issued by UBS AG (“UBS”), and all payments on the Buffered PLUS are subject to the credit risk of UBS. If UBS were to default on its obligations you may not receive any amounts owed to you under the Buffered PLUS and you could lose some or all of your initial investment.

The estimated initial value of the Buffered PLUS as of the pricing date is expected to be between $962.80 and $992.80. The range of the estimated initial value of the Buffered PLUS was determined on the date hereof by reference to UBS’ internal pricing models, inclusive of the internal funding rate. For more information about secondary market offers and the estimated initial value of the Buffered PLUS, see “Risk Factors — Estimated Value Considerations” and “— Risks Relating to Liquidity and Secondary Market Price Considerations” beginning on page 16 herein.

Notice to investors: the Buffered PLUS are significantly riskier than conventional debt instruments. The issuer is not necessarily obligated to repay the full stated principal amount of the Buffered PLUS at maturity, and the Buffered PLUS may have downside market risk proportionate to that of an investment in the underlying index, subject to the buffer amount. This market risk is in addition to the credit risk inherent in purchasing a debt obligation of UBS. You should not purchase the Buffered PLUS if you do not understand or are not comfortable with the significant risks involved in investing in the Buffered PLUS.

You should carefully consider the risks described under “Risk Factors” beginning on page 15 herein and under “Risk Factors” beginning on page PS-9 of the accompanying product supplement before purchasing any Buffered PLUS. Events relating to any of those risks, or other risks and uncertainties, could adversely affect the market value of, and the return on, your Buffered PLUS. You may lose some or almost all of your initial investment in the Buffered PLUS.

Neither the Securities and Exchange Commission nor any other regulatory body has approved or disapproved of these Buffered PLUS or passed upon the adequacy or accuracy of this document, the accompanying product supplement, the accompanying index supplement or the accompanying prospectus. Any representation to the contrary is a criminal offense.

The Buffered PLUS are not bank deposits and are not insured by the Federal Deposit Insurance Corporation or any other governmental agency.

Investment Overview

Buffered Performance Leveraged Upside Securities

The Buffered PLUS Based on the Performance of the S&P 500® Index due August 5, 2025 can be used:

￭As an alternative to direct exposure to the underlying index that enhances the return for a certain range of positive performance of the underlying index; however, by investing in the Buffered PLUS, you will not be entitled to receive any dividends paid with respect to the stocks comprising the underlying index (the “index constituent stocks”) or any interest payments, and your return will not exceed the maximum payment at maturity. You should carefully consider whether an investment that does not provide for any dividends, interest payments or exposure to the positive performance of the underlying index beyond a level that, when multiplied by the leverage factor, exceeds the maximum gain is appropriate for you.

￭To enhance returns and potentially outperform the underlying index in a moderately bullish scenario.

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

￭To provide a return of the stated principal amount in the event that the underlying return is negative and the percentage decline from the initial level to the final level is equal to or less than the buffer amount.

Maturity:	Approximately 15 months
Leverage factor:	2.0
Buffer amount:	10%
Maximum payment at maturity:	$1,147.00 per Buffered PLUS, which is equal to $1,000.00 + ($1,000.00 × Maximum Gain)
Maximum Gain:	14.70%
Interest:	None
Minimum payment at maturity:	$100.00 (10% of the stated principal amount).
Listing:	The Buffered PLUS will not be listed or displayed on any securities exchange or any electronic communications network.

Key Investment Rationale

Investors can use the Buffered PLUS to leverage returns by a factor of 2.0, up to the maximum gain, and obtain contingent protection against a loss of the stated principal amount in the event that the underlying return is zero or negative and the percentage decline from the initial level to the final level is equal to or less than the buffer amount. At maturity, investors will receive an amount in cash based upon the underlying return. Investors may lose some or almost all of their initial investment in the Buffered PLUS.

Investors will not be entitled to receive any dividends paid with respect to the index constituent stocks and the Buffered PLUS do not pay periodic interest. You should carefully consider whether an investment that does not provide for any dividends or periodic interest is appropriate for you.

Leveraged Performance	The Buffered PLUS offer investors an opportunity to capture enhanced returns relative to a hypothetical direct investment in the underlying index or the index constituent stocks, within a certain range of positive performance.
Buffer Feature	If the underlying return of the Buffered PLUS is zero or negative, at maturity, and the percentage decline from the initial level to the final level is equal to or less than the buffer amount, you will receive your stated principal amount even though the level of the underlying index has depreciated.
Upside Scenario	If the underlying return is positive, at maturity, the Buffered PLUS redeem for the lesser of (a) the stated principal amount of $1,000.00 plus the leveraged upside payment and (b) the maximum payment at maturity.
Par Scenario	If the underlying return is zero or negative, at maturity, and the percentage decline from the initial level to the final level is equal to or less than the buffer amount, you will receive the stated principal amount.
Downside Scenario	If the underlying return is negative and the percentage decline from the initial level to the final level is greater than the buffer amount, at maturity, you will receive less than the stated principal amount, resulting in a percentage loss of your initial investment equal to the percentage decline in excess of the buffer amount. For example, if the underlying return is −50%, each Buffered PLUS will redeem for $600.00, or 60% of the stated principal amount. The minimum payment at maturity is only 10% of the stated principal amount and you could lose some or almost all of your initial investment.

Additional Information About the Buffered PLUS

General Information
Listing:	The Buffered PLUS will not be listed or displayed on any securities exchange or any electronic communication network.
Tax considerations:	The U.S. federal income tax consequences of your investment in the Buffered PLUS are uncertain. There are no statutory provisions, regulations, published rulings or judicial decisions addressing the characterization for U.S. federal income tax purposes of securities with terms that are substantially the same as the Buffered PLUS. Some of these tax consequences are summarized below, but we urge you to read the more detailed discussion in “Material U.S. Federal Income Tax Consequences”, including the section “— Securities Treated as Prepaid Derivatives or Prepaid Forwards” in the accompanying product supplement and to discuss the tax consequences of your particular situation with your tax advisor. This discussion is based upon the U.S. Internal Revenue Code of 1986, as amended (the “Code”), final, temporary and proposed U.S. Department of the Treasury (the “Treasury”) regulations, rulings and decisions, in each case, as available and in effect as of the date hereof, all of which are subject to change, possibly with retroactive effect. Tax consequences under state, local and non-U.S. laws are not addressed herein. No ruling from the U.S. Internal Revenue Service (the “IRS”) has been sought as to the U.S. federal income tax consequences of your investment in the Buffered PLUS, and the following discussion is not binding on the IRS. U.S. Tax Treatment. Pursuant to the terms of the Buffered PLUS, UBS and you agree, in the absence of a statutory or regulatory change or an administrative determination or judicial ruling to the contrary, to characterize the Buffered PLUS as prepaid derivative contracts with respect to the underlying index. If your Buffered PLUS are so treated, you should generally recognize gain or loss upon the taxable disposition of your Buffered PLUS. Such gain or loss should generally be long-term capital gain or loss if you hold your Buffered PLUS for more than one year (otherwise such gain or loss would be short-term capital gain or loss if held for one year or less) in an amount equal to the difference between the amount you receive at such time and the amount you paid for your Buffered PLUS. The deductibility of capital losses is subject to limitations. Based on certain factual representations received from us, our special U.S. tax counsel, Cadwalader, Wickersham & Taft LLP, is of the opinion that it would be reasonable to treat your Buffered PLUS in the manner described above. However, because there is no authority that specifically addresses the tax treatment of the Buffered PLUS, it is possible that your Buffered PLUS could alternatively be treated for tax purposes as a single contingent payment debt instrument, or pursuant to some other characterization, such that the timing and character of your income from the Buffered PLUS could differ materially and adversely from the treatment described above, as described further under “Material U.S. Federal Income Tax Consequences”, including the section “— Securities Treated as Prepaid Derivatives or Prepaid Forwards”, in the accompanying product supplement. Notice 2008-2. In 2007, the IRS released a notice that may affect the taxation of holders of the Buffered PLUS. According to Notice 2008-2, the IRS and the Treasury are actively considering whether the holder of an instrument similar to the Buffered PLUS should be required to accrue ordinary income on a current basis. It is not possible to determine what guidance they will ultimately issue, if any. It is possible, however, that under such guidance, holders of the Buffered PLUS will ultimately be required to accrue income currently and this could be applied on a retroactive basis. The IRS and the Treasury are also considering other relevant issues, including whether additional gain or loss from such instruments should be treated as ordinary or capital, whether non-U.S. holders of such instruments should be subject to withholding tax on any deemed income accruals and whether the special “constructive ownership rules” of Section 1260 of the Code should be applied to such instruments. Both U.S. and non-U.S. holders are urged to consult their tax advisors concerning the significance, and the potential impact, of the above considerations.

Medicare Tax on Net Investment Income. U.S. holders that are individuals, estates or certain trusts are subject to an additional 3.8% tax on all or a portion of their “net investment income”, which may include any income or gain realized with respect to the Buffered PLUS, to the extent of their net investment income that when added to their other modified adjusted gross income, exceeds $200,000 for an unmarried individual, $250,000 for a married taxpayer filing a joint return (or a surviving spouse), $125,000 for a married individual filing a separate return or the amount at which the highest tax bracket begins for an estate or trust. The 3.8% Medicare tax is determined in a different manner than the income tax. U.S. holders should consult their tax advisors with respect to their consequences with respect to the 3.8% Medicare tax.

Specified Foreign Financial Assets. Certain U.S. holders that own “specified foreign financial assets” in excess of an applicable threshold may be subject to reporting obligations with respect to such assets with their tax returns, especially if such assets are held outside the custody of a U.S. financial institution. U.S. holders are urged to consult their tax advisors as to the application of this legislation to their ownership of the Buffered PLUS.

Non-U.S. Holders. Subject to Section 871(m) of the Code and FATCA (as discussed below), if you are not a U.S. holder, you should generally not be subject to U.S. withholding tax with respect to payments on your Buffered PLUS and you should not be subject to generally applicable information reporting and backup withholding requirements with respect to payments on your Buffered PLUS if you comply with certain certification and identification requirements, including providing us (and/or the applicable withholding agent) with a validly executed and fully completed applicable IRS Form W-8. Subject Section 897 of the Code and Section 871(m) of the Code, discussed below, gain realized from the taxable disposition of a Buffered PLUS generally should not be subject to U.S. tax unless (i) such gain is effectively connected with a trade or business conducted by the non-U.S. holder in the U.S., (ii) the non-U.S. holder is a non-resident alien individual and is present in the U.S. for 183 days or more during the taxable year of such taxable disposition and certain other conditions are satisfied or (iii) the non-U.S. holder has certain other present or former connections with the U.S.

Section 897. We will not attempt to ascertain whether the issuer of any index constituent stock (an “index constituent stock issuer”) would be treated as a “United States real property holding corporation” (“USRPHC”) within the meaning of Section 897 of the Code. We also have not attempted to determine whether the Buffered PLUS should be treated as “United States real property interests” (“USRPI”) as defined in Section 897 of the Code. If any such entity and the Buffered PLUS were so treated, certain adverse U.S. federal income tax consequences could possibly apply, including subjecting any gain to a non-U.S. holder in respect of a Buffered PLUS upon a taxable disposition of the Buffered PLUS to the U.S. federal income tax on a net basis, and the proceeds from such a taxable disposition may be subject to a 15% withholding tax. Non-U.S. holders should consult their tax advisors regarding the potential treatment of any index constituent issuer as a USRPHC and the Buffered PLUS as USRPI.

Section 871(m). A 30% withholding tax (which may be reduced by an applicable income tax treaty) is imposed under Section 871(m) of the Code on certain “dividend equivalents” paid or deemed paid to a non-U.S. holder with respect to a “specified equity-linked instrument” that references one or more dividend-paying U.S. equity securities or indices containing U.S. equity securities. The withholding tax can apply even if the instrument does not provide for payments that reference dividends. Treasury regulations provide that the withholding tax applies to all dividend equivalents paid or deemed paid on specified equity-linked instruments that have a delta of one (“delta-one specified equity-linked instruments”) issued after 2016 and to all dividend equivalents paid or deemed paid on all other specified equity-linked instruments issued after 2017. However, the IRS has issued guidance that states that the Treasury and the IRS intend to amend the effective dates of the Treasury regulations to provide that withholding on dividend equivalents paid or deemed paid will not apply to specified equity-linked instruments that are not delta-one specified equity-linked instruments and are issued before January 1, 2025.

Principal at Risk Securities

Based on our determination that the Buffered PLUS are not “delta-one” with respect to the underlying index or any index constituent stock, our special U.S. tax counsel is of the opinion that the Buffered PLUS should not be delta-one specified equity-linked instruments and thus should not be subject to withholding on dividend equivalents. Our determination is not binding on the IRS, and the IRS may disagree with this determination. Furthermore, the application of Section 871(m) of the Code will depend on our determinations on the date the terms of the Buffered PLUS are set. If withholding is required, we will not make payments of any additional amounts.

Nevertheless, after the date the terms are set, it is possible that your Buffered PLUS could be deemed to be reissued for tax purposes upon the occurrence of certain events affecting the underlying index, index constituent stocks or your Buffered PLUS, and following such occurrence your Buffered PLUS could be treated as delta-one specified equity-linked instruments that are subject to withholding on dividend equivalents. It is also possible that withholding tax or other tax under Section 871(m) of the Code could apply to the Buffered PLUS under these rules if you enter, or have entered, into certain other transactions in respect of the underlying index, index constituent stocks or the Buffered PLUS. If you enter, or have entered, into other transactions in respect of the underlying index, index constituent stocks or the Buffered PLUS, you should consult your tax advisor regarding the application of Section 871(m) of the Code to your Buffered PLUS in the context of your other transactions.

Because of the uncertainty regarding the application of the 30% withholding tax on dividend equivalents to the Buffered PLUS, you are urged to consult your tax advisor regarding the potential application of Section 871(m) of the Code and the 30% withholding tax to an investment in the Buffered PLUS.

Foreign Account Tax Compliance Act. Legislation commonly referred to as the Foreign Account Tax Compliance Act (“FATCA”) generally imposes a withholding tax of 30% on payments to certain non-U.S. entities (including financial intermediaries) with respect to certain financial instruments, unless various U.S. information reporting and due diligence requirements have been satisfied. An intergovernmental agreement between the U.S. and the non-U.S. entity’s jurisdiction may modify these requirements. This legislation generally applies to certain financial instruments that are treated as paying U.S.-source interest or other U.S.-source “fixed or determinable annual or periodical” income (“FDAP income”). Withholding (if applicable) applies to payments of U.S.-source FDAP income but, pursuant to certain Treasury regulations and IRS guidance, does not apply to payments of gross proceeds on the disposition (including upon retirement) of financial instruments. As the treatment of the Buffered PLUS is unclear, it is possible that any payment with respect to the Buffered PLUS could be subject to the FATCA rules. If withholding applies to the Buffered PLUS, we will not be required to pay any additional amounts with respect to amounts withheld. Both U.S. and non-U.S. holders should consult their tax advisors regarding the potential application of FATCA to the Buffered PLUS.

Proposed Legislation. In 2007, legislation was introduced in Congress that, if it had been enacted, would have required holders of securities similar to the Buffered PLUS purchased after the bill was enacted to accrue interest income over the term of such securities despite the fact that there will be no interest payments over the term of such securities.

Furthermore, in 2013, the House Ways and Means Committee released in draft form certain proposed legislation relating to financial instruments. If it had been enacted, the effect of this legislation generally would have been to require instruments such as the Buffered PLUS to be marked to market on an annual basis with all gains and losses to be treated as ordinary, subject to certain exceptions.

It is not possible to predict whether any similar or identical bills will be enacted in the future, or whether any such bill would affect the tax treatment of your Buffered PLUS. You are urged to consult your tax advisor regarding the possible changes in law and their possible impact on the tax treatment of your Buffered PLUS.

Both U.S. and non-U.S. holders are urged to consult their tax advisors concerning the application of U.S. federal income tax laws to their particular situations, as well as any tax consequences of the purchase, beneficial ownership and disposition of the Buffered PLUS arising under the laws of any state, local, non-U.S. or other taxing jurisdiction.

How the Buffered PLUS Work

Hypothetical Examples

The below examples are based on the following terms and are purely hypothetical (the actual terms of your Buffered PLUS are specified on the cover hereof).

Investors will not be entitled to receive any dividends paid with respect to the index constituent stocks or any periodic interest. You should carefully consider whether an investment that does not provide for any dividends or periodic interest is appropriate for you.

Stated principal amount:	$1,000.00 per Buffered PLUS
Leverage factor:	2.0
Hypothetical Initial Level:	5,000
Buffer amount:	10%
Maximum Payment at Maturity:	$1,147.00 per Buffered PLUS
Maximum Gain:	14.70%
Minimum Payment at Maturity:	$100.00 (10% of the stated principal amount)

EXAMPLE 1: The underlying index appreciates over the term of the Buffered PLUS, and investors receive the stated principal amount plus the leveraged upside payment.

Final level	5,250
Underlying Return	(5,250 − 5,000) / 5,000 = 5.00%
Payment at Maturity	= lesser of (a) $1,000.00 + Leveraged Upside Payment and (b) Maximum Payment at Maturity
	= lesser of (a) $1,000.00 + ($1,000.00 × Leverage Factor × Underlying Return) and (b) $1,000.00 + ($1,000.00 × Maximum Gain)
	= lesser of (a) $1,000.00 + ($1,000.00 × 2.0 × 5.00%) and (b) $1,000.00 + ($1,000.00 × 14.70%)
	= lesser of (a) $1,100.00 and (b) $1,147.00
	= $1,100.00 (Payment at Maturity)

In Example 1, the final level is greater than the initial level and the underlying return is 5.00%. Therefore, at maturity, investors receive the stated principal amount plus a return equal to 2.0 times the underlying return, resulting in a payment at maturity of $1,100.00 per Buffered PLUS (a total return of 10%).

EXAMPLE 2: The underlying index appreciates over the term of the Buffered PLUS, and investors receive the maximum payment at maturity.

Final level		6,125
Underlying Return	(6,125 − 5,000) / 5,000 = 22.50%
Payment at Maturity	= lesser of (a) $1,000.00 + Leveraged Upside Payment and (b) Maximum Payment at Maturity
		= lesser of (a) $1,000.00 + ($1,000.00 × Leverage Factor × Underlying Return) and (b) $1,000.00 + ($1,000.00 × Maximum Gain)
		= lesser of (a) $1,000.00 + ($1,000.00 × 2.0 × 22.50%) and (b) $1,000.00 + ($1,000.00 × 14.70%)
		= lesser of (a) $1,450.00 and (b) $1,147.00
		= $1,147.00 (Payment at Maturity)

In Example 2, the final level is greater than the initial level and the underlying return is 22.50%. Because the underlying return, when multiplied by the leverage factor of 2.0 is greater than the maximum gain, investors receive the maximum payment at maturity, resulting in a payment at maturity of $1,147.00 per Buffered PLUS (a total return of 14.70%).

EXAMPLE 3: The underlying index declines over the term of the Buffered PLUS, and investors receive the stated principal amount at maturity.

Final level	4,750
Underlying Return	(4,750 − 5,000) / 5,000 = −5.00%
Payment at Maturity	= $1,000.00 (Payment at Maturity)

In Example 3, the final level is less than the initial level and the percentage decline from the initial level to the final level is equal to or less than the buffer amount. Because the percentage decline from the initial level to the final level is equal to or less than the buffer amount, even though the underlying return is negative, investors receive the stated principal amount of $1,000.00 per Buffered PLUS (a total return of 0.00%).

EXAMPLE 4: The underlying index declines over the term of the Buffered PLUS, and investors receive less than the stated principal amount at maturity.

Final level	1,750
Underlying Return	(1,750 − 5,000) / 5,000 = −65.00%
Payment at Maturity	= $1,000.00 + [$1,000.00 × (Underlying Return + Buffer Amount)]
	= $1,000.00 + [$1,000.00 × (−65.00% + 10.00%)]
	= $1,000.00 + ($1,000.00 × −55.00%)
	= $1,000.00 − $550.00
	= $450.00 (Payment at Maturity)

In Example 4, the final level is less than the initial level and the percentage decline from the initial level to the final level is greater than the buffer amount. Because the percentage decline from the initial level to the final level is greater than the buffer amount, investors are exposed to the decline in the level of the underlying index in excess of the buffer amount, resulting in a payment at maturity of $450.00 per Buffered PLUS (a loss of 55.00%).

How it works

￭Upside Scenario.If the underlying return is positive, investors will receive the lesser of (a) the stated principal amount of $1,000.00 plus the product of the stated principal amount of $1,000.00 multiplied by the leverage factor of 2.0 multiplied by the underlying return and (b) the maximum payment at maturity. Under the hypothetical terms of the Buffered PLUS, an investor will realize the maximum payment at maturity at a final level of 107.35% of the initial level.

￭If the underlying return is 5%, investors will receive a return of 10%, or $1,100.00 per Buffered PLUS.

￭If the underlying return is 7.35%, investors will receive only the maximum payment at maturity of $1,147.00 per Buffered PLUS, a return of 14.70%.

￭If the underlying return is 30%, investors will receive only the maximum payment at maturity of $1,147.00 per Buffered PLUS, a return of 14.70%.

￭Par Scenario. If the underlying return is zero or negative but the percentage decline from the initial level to the final level is equal to or less than the buffer amount, investors will receive an amount equal to the $1,000.00 stated principal amount.

￭If the underlying return is −5%, investors will receive an amount equal to the $1,000.00 stated principal amount.

￭Downside Scenario. If the underlying return is negative and the percentage decline from the initial level to the final level is greater than the buffer amount, investors will receive an amount that is less than the $1,000.00 stated principal amount, resulting in a loss of their initial investment that is proportionate to the decline in the level of the underlying index over the term of the Buffered PLUS in excess of the buffer amount.

￭If the underlying return is −40%, investors would lose 30% of the stated principal amount and receive only $700.00 per Buffered PLUS at maturity, or 70% of the stated principal amount. The Buffered PLUS do not guarantee the return of the full stated principal amount and investors may lose some or almost all of their initial investment.

Principal at Risk Securities

Payment at Maturity

At maturity, investors will receive for each $1,000.00 stated principal amount of Buffered PLUS that they hold an amount in cash based upon the underlying return of the underlying index on the valuation date, as determined as follows:

If the underlying return is positive:

The lesser of (a) $1,000.00 + leveraged upside payment and (b) the maximum payment at maturity

In no event will the payment at maturity be greater than the maximum payment at maturity.

If the underlying return is zero or negative and the percentage decline from the initial level to the final level is equal to or less than the buffer amount:

The Stated Principal Amount of $1,000.00

If the underlying return is negative and the percentage decline from the initial level to the final level is greater than the buffer amount:

$1,000.00 + [$1,000.00 × (Underlying Return + Buffer Amount)]

Accordingly, if the final level is less than the initial level and the percentage decline of the underlying index from the initial level to the final level is greater than the buffer amount, you will lose a percentage of your stated principal amount equal to the percentage decline in excess of the buffer amount, and in extreme situations, you could lose almost all of your initial investment.

Risk Factors

The following is a non-exhaustive list of certain key risk factors for investors in the Buffered PLUS. For further discussion of these and other risks, you should read the section entitled “Risk Factors” in the accompanying product supplement and “Considerations Relating to Indexed Securities” in the accompanying prospectus. We also urge you to consult your investment, legal, tax, accounting and other advisors concerning an investment in the Buffered PLUS.

Risks Relating to Return Characteristics

￭The Buffered PLUS do not pay interest or guarantee return of the stated principal amount and your investment in the Buffered PLUS may result in a loss. The terms of the Buffered PLUS differ from those of ordinary debt securities in that the Buffered PLUS do not pay interest or guarantee the return of any of the stated principal amount at maturity. If the underlying return is negative and the percentage decline of the underlying index from the initial level to the final level is greater than the buffer amount, you will lose a percentage of your stated principal amount equal to the percentage decline of the underlying index from the initial level to the final level in excess of the buffer amount, and in extreme situations, you could lose almost all of your initial investment. Accordingly, you could lose some and, in extreme situations, almost all of your initial investment.

￭Your potential return on the Buffered PLUS is limited to the maximum gain. The return potential of the Buffered PLUS is limited to the maximum gain indicated on the cover hereof. Therefore, you will not benefit from any positive underlying return in excess of an amount that, when multiplied by the leverage factor, exceeds the maximum gain and your return on the Buffered PLUS may be less than that of a hypothetical direct investment in the underlying index or the index constituent stocks.

￭The leverage factor applies only if you hold the Buffered PLUS to maturity. You should be willing to hold the Buffered PLUS to maturity. If you are able to sell the Buffered PLUS prior to maturity in the secondary market, the price you receive will likely not reflect the full economic value of the leverage factor and the return you realize may be less than the leverage factor multiplied by the then-current underlying return even if such return is positive and does not exceed the maximum gain. You can receive the full benefit of the leverage factor, subject to the maximum gain, from UBS only if you hold the Buffered PLUS to maturity.

￭The contingent repayment of principal at maturity applies only at maturity. You should be willing to hold the Buffered PLUS to maturity. If you are able to sell the Buffered PLUS prior to maturity in the secondary market, you may have to sell them at a loss relative to yourinitial investment even if the then-current level of the underlying index is negative and the percentage decline of the underlying index from the initial level to the final level is equal to or less than the buffer amount.

￭Owning the Buffered PLUS is not the same as owning the index constituent stocks. The return on the Buffered PLUS may not reflect the return you would realize if you actually owned the index constituent stocks. For example, your return on the Buffered PLUS is limited to the maximum gain, while the potential return on a direct investment in the index constituent stocks would be unlimited. Furthermore, you will not receive or be entitled to receive any dividend payments or other distributions during the term of the Buffered PLUS, and any such dividends or distributions will not be factored into the calculation of the payment at maturity on the Buffered PLUS. In addition, as an owner of the Buffered PLUS, you will not have voting rights or any other rights that a holder of the index constituent stocks would have.

Risks Relating to Characteristics of the Underlying Index

￭Market risk. The return on the Buffered PLUS, which may be positive or negative, is linked to the performance of the underlying index and indirectly linked to the value of the index constituent stocks. The level of the underlying index can rise or fall sharply due to factors specific to the underlying index or its index constituent stocks, such as stock or commodity price volatility, earnings, financial conditions, corporate, industry and regulatory developments, management changes and decisions and other events, as well as general market factors, such as general stock market or commodity market volatility and levels, interest rates and economic and political conditions. You, as an investor in the Buffered PLUS, should conduct your own investigation into the underlying index and index constituent stocks.

May 2024 Page 15

Buffered PLUSSM due August 5, 2025

$● Based on the Performance of the S&P 500® Index

Principal at Risk Securities

￭There can be no assurance that the investment view implicit in the Buffered PLUS will be successful. It is impossible to predict whether and the extent to which the level of the underlying index will rise or fall and there can be no assurance that the underlying return will be positive. The final level (and therefore the underlying return) will be influenced by complex and interrelated political, economic, financial and other factors that affect the index constituent stock issuers. You should be willing to accept the risks associated with the relevant markets tracked by the underlying index in general and each index constituent stock in particular, and the risk of losing some or almost all of your initial investment.

￭Changes that affect the underlying index, including regulatory changes, will affect the market value of, and return on, your Buffered PLUS.The policies of the index sponsor as specified under “Information About the Underlying Index” (the “index sponsor”), concerning additions, deletions and substitutions of the index constituent stocks and the manner in which the index sponsor takes account of certain changes affecting those index constituent stocks may adversely affect the level of the underlying index. The policies of the index sponsor with respect to the calculation of the underlying index could also adversely affect the level of the underlying index. The index sponsor may discontinue or suspend calculation or dissemination of the underlying index. Further, indices like the underlying index have been, and continue to be, the subject of regulatory guidance and proposal for reform, including the European Union’s Regulation (EU) 2016/1011. The occurrence of a benchmark event (as defined in the accompanying product supplement under “General Terms of the Securities — Discontinuance of, Adjustments to, or Benchmark Event or Change in Law Affecting, an Underlying Index; Alteration of Method of Calculation”), such as the failure of a benchmark (the underlying index) or the administrator (the index sponsor) or user of a benchmark (such as UBS), to comply with the authorization, equivalence or other requirements of the benchmarks regulation, may result in the discontinuation of the relevant benchmark or a prohibition on its use. If these or other events occur, then the calculation agent may select a successor index, reference a replacement basket or use an alternative method of calculation, in each case, in a manner it considers appropriate, or, if it determines that no successor index, replacement basket or alternative method of calculation would be comparable to the original underlying index, it may deem the closing level of the original underlying index on the trading day immediately prior to the date of such event to be its closing level on each applicable date. Such event and potential adjustments are described further in the accompanying product supplement under “— Discontinuance of, Adjustments to, or Benchmark Event or Change in Law Affecting, an Underlying Index; Alteration of Method of Calculation”. Notwithstanding the ability of the calculation agent to make any of the foregoing adjustments, any such change or event could adversely affect the market value of, and return on, the Buffered PLUS.

￭The underlying index reflects price return, not total return. The return on the Buffered PLUS is based on the performance of the underlying index, which reflects the changes in the market prices of the index constituent stocks. It is not, however, linked to a “total return” index or strategy, which, in addition to reflecting those price returns, would also reflect any dividends paid on the index constituent stocks. The return on the Buffered PLUS will not include such a total return feature or dividend component.

￭UBS cannot control actions by the index sponsor and the index sponsor has no obligation to consider your interests. UBS and its affiliates are not affiliated with the index sponsor and have no ability to control or predict the index sponsor’s actions, including any errors in or discontinuation of public disclosure regarding methods or policies relating to the calculation of the underlying index. The index sponsor is not involved in the Buffered PLUS offering in any way and has no obligation to consider your interest as an owner of the Buffered PLUS in taking any actions that might affect the market value of, and any amount payable on, your Buffered PLUS.

Estimated Value Considerations

￭The issue price you pay for the Buffered PLUS will exceed their estimated initial value. The issue price you pay for the Buffered PLUS will exceed their estimated initial value as of the pricing date due to the inclusion in the issue price of the hedging costs, issuance and other costs and projected profits. As of the close of the relevant markets on the pricing date, we will determine the estimated initial value of the Buffered PLUS by reference to our internal pricing models and the estimated initial value of the Buffered PLUS will be set forth in the final pricing supplement. The pricing models used to determine the estimated initial value of the Buffered PLUS incorporate certain variables, including the level of the underlying index, volatility of the underlying index and index constituent stocks, any dividends paid on the index constituent stocks, prevailing interest rates, the term of the Buffered PLUS and our internal funding rate. Our internal funding rate is typically lower than the rate we would pay to issue conventional fixed or floating rate debt securities of a similar term. The hedging costs, issuance and other costs, projected profits and the difference in rates will reduce the economic value of the Buffered PLUS to you. Due to these factors, the estimated initial value of the Buffered PLUS as of the pricing date will be less than the issue price you pay for the Buffered PLUS.

May 2024 Page 16

Buffered PLUSSM due August 5, 2025

$● Based on the Performance of the S&P 500® Index

Principal at Risk Securities

￭The estimated initial value is a theoretical price and the actual price that you may be able to sell your Buffered PLUS in any secondary market (if any) at any time after the pricing date may differ from the estimated initial value. The value of your Buffered PLUS at any time will vary based on many factors, including the factors described above and in “Risks Relating to Characteristics of the Underlying Index —Market risk” above and is impossible to predict. Furthermore, the pricing models that we use are proprietary and rely in part on certain assumptions about future events, which may prove to be incorrect. As a result, after the pricing date, if you attempt to sell the Buffered PLUS in the secondary market, the actual value you would receive may differ, perhaps materially, from the estimated initial value of the Buffered PLUS determined by reference to our internal pricing models. The estimated initial value of the Buffered PLUS does not represent a minimum or maximum price at which we or any of our affiliates would be willing to purchase your Buffered PLUS in any secondary market at any time.

￭Our actual profits may be greater or less than the differential between the estimated initial value and the issue price of the Buffered PLUS as of the pricing date. We may determine the economic terms of the Buffered PLUS, as well as hedge our obligations, at least in part, prior to the pricing date. In addition, there may be ongoing costs to us to maintain and/or adjust any hedges and such hedges are often imperfect. Therefore, our actual profits (or potentially, losses) in issuing the Buffered PLUS cannot be determined as of the pricing date and any such differential between the estimated initial value and the issue price of the Buffered PLUS as of the pricing date does not reflect our actual profits. Ultimately, our actual profits will be known only at the maturity of the Buffered PLUS.

Risks Relating to Liquidity and Secondary Market Price Considerations

￭There may be little or no secondary market for the Buffered PLUS. The Buffered PLUS will not be listed or displayed on any securities exchange or any electronic communications network. UBS Securities LLC and its affiliates intend, but are not required to make a market for the Buffered PLUS and may stop making a market at any time. If you are able to sell your Buffered PLUS prior to maturity, you may have to sell them at a substantial loss. Furthermore, there can be no assurance that a secondary market for the Buffered PLUS will develop. The estimated initial value of the Buffered PLUS does not represent a minimum or maximum price at which we or any of our affiliates would be willing to purchase your Buffered PLUS in any secondary market at any time.

￭Depending on your broker, the price at which UBS Securities LLC and its affiliates may offer to buy the Buffered PLUS in the secondary market (if any) may be less than the valuation provided on your customer account statements. As described above, UBS Securities LLC and its affiliates intend, but are not required, to make a market for the Buffered PLUS and may stop making a market at any time. If UBS Securities LLC or an affiliate makes secondary markets in the Buffered PLUS, it will do so at prices that reflect our estimated value determined by reference to our internal pricing models at that time, as well as its then current bid-ask spread for similar sized trades of structured debt securities. The value provided by UBS Securities LLC on its customer statements is based on these pricing models. As a result, depending on your broker, UBS Securities LLC or its affiliates may offer to buy or sell the Buffered PLUS in the secondary market at a price that is less than the valuation provided on your broker’s customer account statements. Investors should inquire as to the valuation provided on customer account statements provided by unaffiliated dealers.

￭Price of the Buffered PLUS prior to maturity. The market price of the Buffered PLUS will be influenced by many unpredictable and interrelated factors, including the level of the underlying index; the volatility of the underlying index and index constituent stocks; any dividends paid on the index constituent stocks; the time remaining to the maturity of the Buffered PLUS; interest rates in the markets; geopolitical conditions and economic, financial, political, force majeure and regulatory or judicial events; the creditworthiness of UBS and the then current bid-ask spread for the Buffered PLUS.

￭Impact of fees and the use of internal funding rates rather than secondary market credit spreads on secondary market prices. All other things being equal, the use of the internal funding rates described above under “—Estimated Value Considerations” as well as the inclusion in the issue price of the hedging costs, issuance and other costs and any projected profits are, expected to reduce the price at which you may be able to sell the Buffered PLUS in any secondary market.

Risks Relating to Hedging Activities and Conflicts of Interest

￭Potential conflict of interest. UBS and its affiliates may engage in business with the index constituent stock issuers or trading activities related to the underlying index or any index constituent stocks, which may present a conflict between the interests of UBS and you, as a holder of the Buffered PLUS. There are also potential conflicts of interest between you and the calculation agent, which will be an affiliate of UBS and which will make potentially subjective judgments. The calculation agent will determine the payment at maturity, if any, based on the observed closing level of the underlying index. The calculation agent can postpone the determination of the initial level or final level (and therefore the original issue date or maturity date, as applicable) if a market disruption event occurs and is continuing on the pricing date or valuation date, respectively. As UBS determines the economic terms of the Buffered PLUS, including the maximum gain and leverage factor and buffer amount, and such terms include the hedging costs, issuance and other costs and projected profits, the Buffered PLUS represent a package of economic terms. There are other potential conflicts of interest insofar as an investor could potentially get better economic terms if that investor entered into exchange-traded and/or OTC derivatives or other instruments with third parties, assuming that such instruments were available and the investor had the ability to assemble and enter into such instruments.

In addition, we or one of our affiliates may enter into swap agreements or related hedging activities with the dealer or its affiliates in connection with the Buffered PLUS, which could cause the economic interests of UBS, the dealer or our or their respective affiliates to be adverse to your interests as an investor in the Buffered PLUS. If the dealer or any of its affiliates conduct hedging activities for us or our affiliate in connection with the Buffered PLUS and earns profits in connection with such hedging activities, such profit will be in addition to the underwriting compensation it receives for the sale of the Buffered PLUS to you. You should be aware that the potential to receive compensation both for hedging activities and sales may create a further incentive for the dealer to sell the Buffered PLUS to you.

￭Hedging and trading activities by the calculation agent and its affiliates could potentially affect the value of, and any amounts payable on, the Buffered PLUS. The hedging or trading activities of the issuer’s affiliates and of any other hedging counterparty with respect to the Buffered PLUS on or prior to the pricing date and prior to maturity could adversely affect the value of, and any amounts payable on, the Buffered PLUS. These hedging or trading activities on or prior to the pricing date could potentially affect the initial level of the underlying index. Additionally, these hedging or trading activities during the term of the Buffered PLUS could potentially affect the final level of the underlying index on the valuation date and, accordingly, any amounts payable on the Buffered PLUS. It is possible that these hedging or trading activities could result in substantial returns for us or our affiliates while the value of the Buffered PLUS declines.

￭Potentially inconsistent research, opinions or recommendations by UBS. UBS and its affiliates publish research from time to time on financial markets and other matters that may influence the value of the Buffered PLUS, or express opinions or provide recommendations that are inconsistent with purchasing or holding the Buffered PLUS. Any research, opinions or recommendations expressed by UBS or its affiliates may not be consistent with each other and may be modified from time to time without notice. Investors should make their own independent investigation of the merits of investing in the Buffered PLUS and the underlying index.

￭Potential UBS impact on price. Trading or hedging transactions by UBS and/or its affiliates in any index constituent stock, listed and/or over-the-counter options, futures, exchange-traded funds or other instruments with returns linked to the performance of the underlying index or index constituent stocks may adversely affect the level of the underlying index, the performance and, therefore, the market value of, and any amount payable on, the Buffered PLUS.

Risks Relating to General Credit Characteristics

￭Credit risk of UBS. The Buffered PLUS are unsubordinated, unsecured debt obligations of UBS, and are not, either directly or indirectly, an obligation of any third party. Any payment to be made on the Buffered PLUS, including any repayment of principal at maturity, depends on the ability of UBS to satisfy its obligations as they come due. As a result, UBS’ actual and perceived creditworthiness may affect the market value of the Buffered PLUS. If UBS were to default on its obligations, you may not receive any amounts owed to you under the terms of the Buffered PLUS, you could lose all of your initial investment.

￭The Buffered PLUS are not bank deposits. An investment in the Buffered PLUS carries risks which are very different from the risk profile of a bank deposit placed with UBS or its affiliates. The Buffered PLUS have different yield and/or return, liquidity and risk profiles and would not benefit from any protection provided to deposits.

￭If UBS experiences financial difficulties, FINMA has the power to open restructuring or liquidation proceedings in respect of, and/or impose protective measures in relation to, UBS, which proceedings or measures may have a material adverse effect on the terms and market value of the securities and/or the ability of UBS to make payments thereunder. The Swiss Federal Act on Banks and Savings Banks of November 8, 1934, as amended (the “Swiss Banking Act”) grants the Swiss Financial Market Supervisory Authority (“FINMA”) broad powers to take measures and actions in relation to UBS if it concludes that there is justified concern that UBS is over-indebted or has serious liquidity problems or, after expiry of a deadline, UBS fails to fulfill the applicable capital adequacy requirements (whether on a standalone or consolidated basis). If one of these pre-requisites is met, FINMA is authorized to open restructuring proceedings or liquidation (bankruptcy) proceedings in respect of, and/or impose protective measures in relation to, UBS. The Swiss Banking Act grants significant discretion to FINMA in connection with the aforementioned proceedings and measures. In particular, a broad variety of protective measures may be imposed by FINMA, including a bank moratorium or a maturity postponement, which measures may be ordered by FINMA either on a stand-alone basis or in connection with restructuring or liquidation proceedings.

In restructuring proceedings, FINMA, as resolution authority, is competent to approve the restructuring plan. The restructuring plan may, among other things, provide for (a) the transfer of all or a portion of UBS’ assets, debts, other liabilities and contracts (which may or may not include the contractual relationship between UBS and the holders of securities) to another entity, (b) a stay (for a maximum of two business days) on the termination of contracts to which UBS is a party, and/or the exercise of (w) rights to terminate, (x) netting rights, (y) rights to enforce or dispose of collateral or (z) rights to transfer claims, liabilities or collateral under contracts to which UBS is a party, (c) the partial or full conversion of UBS’ debt and/or other obligations, including its obligations under the securities, into equity (a “debt-to-equity” swap), and/or (d) the partial or full write-off of obligations owed by UBS (a “write-off”), including its obligations under the securities. Prior to any debt-to-equity swap or write-off with respect to any securities, outstanding equity and debt instruments issued by UBS qualifying as additional tier 1 capital or tier 2 capital must be converted or written-down, as applicable, and cancelled. The Swiss Banking Act addresses the order in which a debt-to-equity swap or a write-off of debt instruments (other than debt instruments qualifying as additional tier 1 capital or tier 2 capital) should occur: first, all subordinated obligations not qualifying as regulatory capital; second, debt instruments for loss absorbency in the course of insolvency measures (Schuldinstrumente zur Verlusttragung im Falle von Insolvenzmassnahmen) under the Swiss Ordinance concerning Capital Adequacy and Risk Diversification for Banks and Securities Dealers of June 1, 2012, as amended; third, all other obligations not excluded by law from a debt-to-equity swap or write-off (other than deposits), such as the securities; and fourth, deposits to the extent in excess of the amount privileged by law. However, given the broad discretion granted to FINMA, any restructuring plan approved by FINMA in connection with restructuring proceedings with respect to UBS could provide that the claims under or in connection with the securities will be fully or partially converted into equity or written-off, while preserving other obligations of UBS that rank pari passu with UBS’ obligations under the securities. Consequently, the exercise by FINMA of any of its statutory resolution powers or any suggestion of any such exercise could materially adversely affect the rights of holders of the securities, the price or value of their investment in the securities and/or the ability of UBS to satisfy its obligations under the securities and could lead to holders losing some or all of their investment in the securities.

Once FINMA has opened restructuring proceedings with respect to UBS, it may consider factors such as the results of operations, financial condition (in particular, the level of indebtedness, potential future losses and/or restructuring costs), liquidity profile and regulatory capital adequacy of UBS and its subsidiaries, or any other factors of its choosing, when determining whether to exercise any of its statutory resolution powers with respect to UBS, including, if it chooses to exercise such powers to order a debt-to- equity swap and/or a write-off, whether to do so in full or in part. The criteria that FINMA may consider in exercising any statutory resolution power provide it with considerable discretion. Therefore, holders of the securities may not be able to refer to publicly available criteria in order to anticipate a potential exercise of any such power and, consequently, its potential effects on the securities and/or UBS.

If UBS were to be subject to restructuring proceedings, the creditors whose claims are affected by the restructuring plan would not have a right to vote on, reject, or seek the suspension of the restructuring plan. In addition, if a restructuring plan with respect to UBS has been approved by FINMA, the rights of a creditor to challenge the restructuring plan or have the restructuring plan reviewed by a judicial or administrative process or otherwise (e.g., on the grounds that the plan would unduly prejudice the rights of holders of securities or otherwise be in violation of the Swiss Banking Act) are very limited. Even if any of UBS’ creditors were to successfully challenge the restructuring plan in court, the court could only require the relevant creditors to be compensated ex post and there is currently no guidance as to on what basis such compensation would be

calculated and how it would be funded. Any such challenge (even if successful) would not suspend, or result in the suspension of, the implementation of the restructuring plan.

Risks Relating to U.S. Federal Income Taxation

￭Uncertain tax treatment. Significant aspects of the tax treatment of the Buffered PLUS are uncertain. You should read carefully the section entitled “Tax Considerations” herein and the section entitled “Material U.S. Federal Income Tax Consequences”, including the section “— Securities Treated as Prepaid Derivatives or Prepaid Forwards”, in the accompanying product supplement and consult your tax advisor about your tax situation.
