UBS AG $• Trigger Autocallable Notes

Linked to the Solactive U.S. Large Cap Volatility Navigator 40 Index due on or about November 29, 2030

**Investment Description**

UBS AG Trigger Autocallable Notes (the "Notes") are unsubordinated, unsecured debt obligations issued by UBS AG ("UBS" or the "issuer") linked to the Solactive U.S. Large Cap Volatility Navigator 40 Index (the "underlying asset"). UBS will automatically call the Notes (an "automatic call") if the closing level of the underlying asset on any observation date, including the final valuation date, is equal to or greater than the call threshold level, which is equal to a percentage of the initial level as specified below. If the Notes are subject to an automatic call, UBS will pay you on the applicable call settlement date following such observation date a cash payment per Note equal to the "call price", which is your principal amount plus a call return based on the call return rate and no further payments will be owed to you under the Notes. The call return increases the longer the Notes are outstanding. If the Notes are not subject to an automatic call and the closing level of the underlying asset on the final valuation date (its "final level") is equal to or greater than the downside threshold, at maturity, UBS will pay you a cash payment per Note equal to the principal amount. If, however, the Notes are not subject to an automatic call and the final level is less than the downside threshold, at maturity, UBS will pay you a cash payment per Note that is less than the principal amount, if anything, resulting in a percentage loss on your initial investment equal to the percentage decline in the underlying asset from the initial level to the final level and, in extreme situations, you could lose all of your initial investment. **Investing in the Notes involves significant risks. You will lose a significant portion or all of your initial investment if the Notes are not subject to an automatic call. Higher call return rates are generally associated with a greater risk of loss and a greater risk that the Notes will not be subject to an automatic call. The contingent repayment of principal only applies if you hold the Notes until the maturity date. Any payment on the Notes, including any repayment of principal, is subject to the creditworthiness of UBS. If UBS were to default on its obligations, you may not receive any amounts owed to you under the Notes and you could lose all of your initial investment.**

**Features**

---

| | |
|:---|:---|
| ❑ | **Automatic Call Feature** — UBS will automatically call the Notes if the closing level of the underlying asset is equal to or greater than the call threshold level on any observation date, including the final valuation date. If the Notes are subject to an automatic call, UBS will pay you on the applicable call settlement date a cash payment per Note equal to the call price for the relevant observation date. The call return increases the longer the Notes are outstanding. Following an automatic call, no further payments will be owed to you on the Notes. If the Notes are not subject to an automatic call, investors will have the potential for downside market risk at maturity. |
| ❑ | **Contingent Repayment of Principal Amount at Maturity with Potential for Full Downside Market Exposure** — If the Notes are not subject to an automatic call and the final level is equal to or greater than the downside threshold, at maturity, UBS will pay you a cash payment per Note equal to the principal amount. If, however, the Notes have not been subject to an automatic call and the final level is less than the downside threshold, at maturity, UBS will pay you a cash payment per Note that is less than the principal amount, if anything, resulting in a percentage loss on your initial investment that is equal to the underlying return and, in extreme situations, you could lose all of your initial investment. The contingent repayment of principal applies only if you hold the Notes until the maturity date. Any payment on the Notes, including any repayment of principal, is subject to the creditworthiness of UBS. |

Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), trades in the secondary market generally are required to settle in one business day (T+1), unless the parties to a trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes in the secondary market on any date prior to one business day before delivery of the Notes will be required, by virtue of the fact that each Note initially will settle in three business days (T+3), to specify alternative settlement arrangements to prevent a failed settlement of the secondary market trade. | We expect to deliver the Notes against payment on the third business day following the trade date.

**Notice to investors: the Notes are significantly riskier than conventional debt instruments. The issuer is not necessarily obligated to repay the principal amount of the Notes at maturity, and the Notes may have the same downside market risk as that of the underlying asset. This market risk is in addition to the credit risk inherent in purchasing a debt obligation of UBS. You should not purchase the Notes if you do not understand or are not comfortable with the significant risks involved in investing in the Notes.**

**You should carefully consider the risks described under "Key Risks" beginning on page 4 and under "Risk Factors" beginning on page PS-9 of the accompanying product supplement. Events relating to any of those risks, or other risks and uncertainties, could adversely affect the market value of, and the return on, your Notes. You may lose a significant portion or all of your initial investment in the Notes. The Notes will not be listed or displayed on any securities exchange or any electronic communications network.**

**Note Offering**

The final terms of the Notes will be set on the trade date.

\* The call return is based on the call return rate and will vary depending on whether, and if called, the call settlement date on which, the Notes are called.

The estimated initial value of the Notes as of the trade date is expected to be between $924.50 and $954.50. The range of the estimated initial value of the Notes was determined on the date hereof by reference to UBS' internal pricing models, inclusive of the internal funding rate.

<sup>(1)</sup> Notwithstanding the underwriting discount received by one or more third-party dealers from UBS Securities LLC described below, certain registered investment advisers or fee-based advisory accounts unaffiliated from UBS may purchase Notes from a third-party dealer at a purchase price of at least $990.00 per Note, and such third-party dealer, with respect to such sales, may forgo some or all of the underwriting discount.

<sup>(2)</sup> Our affiliate, UBS Securities LLC, will receive an underwriting discount of $10.00 per Note sold in this offering. UBS Securities LLC intends to either re-allow the full amount of this discount to one or more third-party dealers or to offer the Notes directly to investors at the issue price to the public. Certain of such third-party dealers may resell the Notes to other securities dealers at the issue price to public less an underwriting discount of up to the underwriting discount received. UBS Securities LLC may also pay another unaffiliated dealer a marketing fee of $10.00 per Note with respect to some or all of the Notes in connection with its marketing efforts. The marketing fee will be deducted from amounts remitted to UBS

**Investor Suitability**

**The Notes may be suitable for you if:**

♦You fully understand the risks inherent in an investment in the Notes, including the risk of loss of a significant portion or all of your initial investment.

♦You can tolerate a loss of a significant portion or all of your initial investment and are willing to make an investment that may have the same downside market risk as that of a hypothetical investment in the underlying asset or the stocks comprising the underlying asset (the "underlying constituents").

♦You are willing to invest in the Notes based on the call threshold level and downside threshold specified on the cover hereof.

♦You believe that the closing level of the underlying asset will be equal to or greater than the call threshold level on one of the specified observation dates, including the final valuation date, and you believe that the level of the underlying asset will appreciate over the term of the Notes by a percentage that is less than the applicable call return.

♦You understand and accept that you will not participate in any appreciation in the level of the underlying asset and that your potential return is limited to the call return (which increases the longer the Notes remain outstanding), which will be based on the duration of the Notes, and you are willing to invest in the Notes based on the call return rate indicated on the cover hereof.

♦You can tolerate fluctuations in the price of the Notes prior to maturity that may be similar to or exceed the downside fluctuations in the level of the underlying asset.

♦You do not seek current income and are willing to forgo any dividends paid on the underlying constituents.

♦You are willing to invest in Notes that may be subject to an automatic call and you are otherwise willing to hold such Notes to maturity and accept that there may be little or no secondary market for the Notes.

♦You understand and are willing to accept the risks associated with the underlying asset.

♦You are willing to assume the credit risk of UBS for all payments under the Notes, and understand that if UBS defaults on its obligations you may not receive any payments due to you including any repayment of principal.

♦You understand that the estimated initial value of the Notes determined by our internal pricing models is lower than the issue price and that should UBS Securities LLC or any affiliate make secondary markets for the Notes, the price (not including their customary bid-ask spreads) will temporarily exceed the internal pricing model price.

**The Notes may not be suitable for you if:**

♦You do not fully understand the risks inherent in an investment in the Notes, including the risk of loss of a significant portion or all of your initial investment.

♦You cannot tolerate a loss of a significant portion or all of your initial investment or you are not willing to make an investment that may have the same downside market risk as that of a hypothetical investment in the underlying asset or the underlying constituents.

♦You are unwilling to invest in the Notes based on the call threshold level or downside threshold specified on the cover hereof.

♦You believe that the closing level of the underlying asset will decline during the term of the Notes and, therefore, is likely to be less than the call threshold level on the specified observation dates, including the final valuation date, or that the level of the underlying asset will appreciate over the term of the Notes by a percentage that is greater than the applicable call return.

♦You seek an investment that participates in the appreciation in the level of the underlying asset or that has unlimited return potential, or you are unwilling to invest in the Notes based on the call return rate indicated on the cover hereof.

♦You cannot tolerate fluctuations in the price of the Notes prior to maturity that may be similar to or exceed the downside fluctuations in the level of the underlying asset.

♦You seek current income or prefer to receive any dividends paid on the underlying constituents.

♦You are unable or unwilling to hold Notes that may be subject to an automatic call, or you are otherwise unable or unwilling to hold such Notes to maturity or you seek an investment for which there will be an active secondary market.

♦You do not understand or are unwilling to accept the risks associated with the underlying asset.

♦You are not willing to assume the credit risk of UBS for all payments under the Notes, including any repayment of principal.

**The suitability considerations identified above are not exhaustive. Whether or not the Notes are a suitable investment for you will depend on your individual circumstances. You are urged to consult your investment, legal, tax, accounting and other advisors and carefully consider the suitability of an investment in the Notes in light of your particular circumstances. You should review "Information About the Underlying Asset" herein for more information on the underlying asset. You should also review carefully the "Key Risks" section herein for risks related to an investment in the Notes.**

**Investing in the Notes involves significant risks. You may lose a significant portion or all of your initial investment. Any payment on the Notes, including any repayment of principal, is subject to the creditworthiness of UBS. If UBS were to default on its obligations, you may not receive any amounts owed to you under the Notes and you could lose all of your initial investment.**

**You will lose a significant portion or all of your initial investment if the Notes are not subject to an automatic call and the final level is less than the downside threshold.**

------

**Key Risks**

An investment in the Notes involves significant risks. Investing in the Notes is not equivalent to a hypothetical investment in the underlying asset. Some of the key risks that apply to the Notes are summarized below, but we urge you to read the more detailed explanation of risks relating to the Notes in the "Risk Factors" section of the accompanying product supplement. We also urge you to consult your investment, legal, tax, accounting and other advisors concerning an investment in the Notes.

***Risks Relating to Return Characteristics***

♦**Risk of loss at maturity** — The Notes differ from ordinary debt securities in that UBS will not necessarily repay the full principal amount of the Notes at maturity. If the Notes are not subject to an automatic call and the final level is less than the downside threshold you will lose a percentage of your principal amount equal to the underlying return and in extreme situations, you could lose all of your initial investment.

♦**The stated payout from the issuer applies only if you hold your Notes to maturity** — You should be willing to hold your Notes to maturity. If you are able to sell your Notes prior to an automatic call or maturity in the secondary market, you may have to sell them at a loss relative to your initial investment even if the level of the underlying asset at such time is equal to or greater than the downside threshold. All payments on the Notes are subject to the creditworthiness of UBS.

♦**Your potential return on the Notes is limited to any call return, you will not participate in any appreciation in the level of the underlying asset or any underlying constituents and you will not have the same rights as holders of any underlying constituents** — The return potential of the Notes is limited to the pre-specified call return resulting from an automatic call, if applicable, and you will not participate in any appreciation in the level of the underlying asset. The Notes will only be subject to an automatic call if the closing level or the final level, as applicable, of the underlying asset on an observation date is equal to or greater than the call threshold level. Because the call return increases the longer the Notes have been outstanding, the call price payable with respect to earlier observation dates is less than the call price payable with respect to later observation dates. The earlier the Notes are subject to an automatic call, the lower your return on the Notes will be. Because the Notes may be subject to an automatic call as early as the first potential call settlement date, the total return on the Notes could be less than if the Notes remained outstanding until maturity. Further, if the Notes are not subject to an automatic call and the final level is less than the downside threshold you will be subject to the decline in the level of the underlying asset even though you cannot participate in any appreciation in the level of the underlying asset. As a result, the return on an investment in the Notes could be less than the return on a hypothetical investment in the underlying asset or underlying constituents. In addition, as an owner of the Notes, you will not have voting rights or any other rights of a holder of any underlying constituents.

♦**A higher call return rate or lower downside threshold or call threshold level may reflect greater expected volatility of the underlying asset, and greater expected volatility generally indicates an increased risk of loss at maturity** — The economic terms for the Notes, including the call return rate, call threshold level and downside threshold, are based, in part, on the expected volatility of the underlying asset at the time the terms of the Notes are set. "Volatility" refers to the frequency and magnitude of changes in the level of the underlying asset. The greater the expected volatility of the underlying asset as of the trade date, the greater the expectation is as of that date that the closing level or final level, as applicable, of the underlying asset could be less than the call threshold level on any observation date (including the final valuation date) and that the final level could be less than the downside threshold and, as a consequence, indicates an increased risk of the Notes not being subject to an automatic call and an increased risk of loss, respectively. All things being equal, this greater expected volatility will generally be reflected in a higher call return rate than the yield payable on our conventional debt securities with a similar maturity or on otherwise comparable securities, and/or a lower downside threshold and/or call threshold level than those terms on otherwise comparable securities. Therefore, a relatively higher call return rate may indicate an increased risk of loss. Further, a relatively lower downside threshold and/or call threshold level may not necessarily indicate that the Notes have a greater likelihood of a return of principal at maturity and/or paying the call price. You should be willing to accept the downside market risk of the underlying asset and the potential to lose a significant portion or all of your initial investment.

♦**Reinvestment risk** — The Notes will be subject to an automatic call if the closing level of the underlying asset is equal to or greater than the call threshold level on any observation date, including the final valuation date, as set forth herein. Because the call threshold level is less than the initial level, the Notes will be subject to an automatic call unless the closing level of the underlying asset declines to a level less than the call threshold level on each observation date. Because the Notes could be subject to an automatic call as early as the first potential call settlement date, the term of your investment may be limited. In the event that the Notes are subject to an automatic call, there is no guarantee that you would be able to reinvest the proceeds at a comparable rate of return and/or with a comparable call return rate for a similar level of risk. In addition, to the extent you are able to reinvest such proceeds in an investment comparable to the Notes, you may incur transaction costs such as dealer discounts and hedging costs built into the price of the new securities. Generally, however, the longer the Notes remain outstanding, the less likely the Notes will be subject to an automatic call due to the decline in the level of the underlying asset and the shorter time remaining for the level of the underlying asset to recover. Such periods generally coincide with a period of greater risk of principal loss on your Notes.

***Risks Relating to Characteristics of the Underlying Asset***

♦**Market risk** — The return on the Notes, which may be negative, is directly linked to the performance of the underlying asset and indirectly linked to the performance of the underlying constituents and their issuers (the "underlying constituent issuers"). The level of the underlying asset can rise or fall sharply due to factors specific to the underlying asset or the underlying constituents, 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 and commodity market volatility and levels, interest rates and economic, political and other conditions. You, as an investor in the Notes, should conduct your own investigation into the underlying asset and underlying constituents.

♦**There can be no assurance that the investment view implicit in the Notes will be successful** — It is impossible to predict whether and the extent to which the level of the underlying asset will rise or fall. There can be no assurance that the closing level or final level, as applicable, of the underlying asset will be equal to or greater than the call threshold level on any observation date (including the final valuation date) or, if the Notes are not subject to an automatic call, that the final level will be equal to or greater than the downside threshold. The level of the underlying asset will be influenced by complex and interrelated political, economic, financial and other factors that affect the underlying constituent issuers. You should be willing to accept the downside risks associated with the underlying asset in general and the underlying constituents in particular, and the risk of losing a significant portion or all of your initial investment.

------

♦**Changes affecting the underlying asset, including regulatory changes, could have an adverse effect on the market value of, and return on, your Notes** — The policies of the index sponsor as specified under "Information About the Underlying Asset" (the "index sponsor"), concerning additions, deletions and substitutions of the underlying constituents and the manner in which the index sponsor takes account of certain changes affecting those underlying constituents may adversely affect the level of the underlying asset. The policies of the index sponsor with respect to the calculation of the underlying asset could also adversely affect the level of the underlying asset. The index sponsor may discontinue or suspend calculation or dissemination of the underlying asset. Further, indices like the underlying asset 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 asset) 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 asset, it may deem the closing level of the original underlying asset on a trading day reasonably proximate to the date of such event to be its closing level on each applicable date. Such events and the 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 Notes.

♦**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 its actions, including any errors in or discontinuation of public disclosure regarding methods or policies relating to the calculation of the underlying asset. The index sponsor is not involved in the Notes offering in any way and has no obligation to consider your interest as an owner of the Notes in taking any actions that might affect the market value of, and return on, your Notes.

♦**The underlying asset includes a 6.0% per annum daily deduction which will adversely affect its performance —** The underlying asset' is subject to a 6.0% per annum daily deduction, or decrement. The level of the underlying asset' will trail the value of an identically constituted synthetic portfolio that is not subject to any such deduction. The underlying asset deduction will place a significant drag on its performance, potentially offsetting any appreciation of, or exacerbating any declines in, the underlying asset. The underlying asset will not appreciate unless the return of its investment strategy is sufficient to offset the negative effects of the index deduction, and then only to the extent that the return of its investment strategy is greater than the index deduction. As a result of the daily decrement, the level of the underlying asset may decline even if the return of its investment strategy is positive. The daily deduction is one of the inputs our internal pricing models use to value the derivative or derivatives underlying the economic terms of the Notes for purposes of determining the estimated value of the Notes set forth on the cover of this pricing supplement and is a variable that affects the economic terms of the Notes. Holding the estimated initial value of the Notes and market conditions constant, the economic terms of the Notes, including the call return rate, downside threshold and call threshold level, are more favorable to you than the terms that would be available on a hypothetical note issued by us linked to an identical underlying asset without a daily deduction. However, there can be no assurance that any improvement in the terms of the Notes derived from the daily deduction will offset any negative effect of the daily deduction on the performance of the underlying asset. The return on the Notes may be lower than the return on a hypothetical note issued by us linked to an identical underlying asset without a daily deduction.

♦**The underlying asset may not be successful or outperform any alternative strategy that might be employed in respect of the futures contracts** — No assurance can be given that the investment strategy on which the underlying asset is based will be successful or that the underlying asset will outperform any alternative strategy that might be employed with respect to the Solactive Future Series 5-Day Roll United States 500 Excess Return USD Index (the "underlying index") or the futures contracts. The underlying asset has been developed based on predetermined rules that may not prove to be advantageous or successful, and will not be adjusted for market conditions.

♦**The underlying asset may not achieve its target volatility —** No assurance can be given that the underlying asset will maintain a realized volatility that approximates its target volatility. The actual realized volatility of the underlying asset may be greater than or less than the target volatility of 40%, which may adversely affect the performance of the underlying asset. On each daily rebalancing day (as defined in "Annex A — Additional Information About the Solactive U.S. Large Cap Volatility Navigator 40 Index" included at the end of this document), the underlying asset's exposure to the underlying index is reweighted, if necessary, based on the greater of the 5-day and 40-day realized volatility of the futures contracts. The underlying asset has a maximum exposure of 500%, which may limit the ability of the underlying asset to achieve the volatility target where achieving the volatility target would require exposure in excess of the maximum amount. Further, realized volatility is backward looking and determined by reference to historical prices (whether historical settlement prices or the time-weighted average price ("TWAP") of traded prices on the relevant date). Accordingly, there is no guarantee that using the realized volatility measure to determine the underlying asset's exposure to the underlying index will actually result in an investment with volatility equal to the target volatility of 40%. In addition, the volatility of the futures contracts on any day may change quickly and unexpectedly. Accordingly, the actual realized annualized volatility of the underlying asset may be greater than or less than the target volatility, which may adversely affect the level of the underlying asset and, therefore, the market value of, and return on, your investment.

♦**The underlying asset is an "excess return" index and not a "total return" index —** The underlying asset and the related underlying index is an "excess return" index and not a "total return" index, which means it measures the returns accrued from investing in uncollateralized futures contracts. As a result, the level of the underlying asset does not benefit from any "collateral return" on any futures contracts (interest on cash deposited as collateral for the purchase of futures contracts) or any dividends or other distributions on any index constituents of the S&P 500<sup>®</sup> Index.

♦**The underlying asset is subject to risks associated with the use of significant leverage —** On each daily rebalancing day, the underlying asset will employ leverage to increase the exposure of the underlying asset to the underlying index if the greater of the 5-day and 40-day realized volatility of the futures contracts is below 40%, subject to a maximum exposure of 500%. Under normal market conditions in the past, the futures contracts would have tended to exhibit a realized volatility below 40%. Accordingly, the underlying asset would have generally employed leverage in the past, except during periods of elevated volatility. When leverage is employed, any movements in the prices of the futures contracts will result in greater changes in the level of the underlying index and, consequently, the underlying asset than if leverage were not used. In particular, the use of leverage will magnify any negative performance of the futures contracts, which, in turn, would negatively affect the performance of the underlying asset. In situations where a significant increase in the greater of the 5-day and 40-day realized volatility is accompanied by a significant decline in the value of the futures contracts, the level of the underlying asset may decline significantly before subsequent rebalancing days when the underlying asset's exposure to the futures contracts would be reduced.

♦**The underlying asset may be significantly uninvested —** On each daily rebalancing day, the underlying asset's exposure to the underlying index will be less than 100% when the relevant realized volatility is above 40%. If the underlying asset's exposure to the underlying index is less than 100%, the underlying asset will not be fully invested in the underlying index, and any uninvested portion will earn no return. The underlying asset may be significantly uninvested on any given day, and will realize only a portion of any gains due to appreciation of the futures contracts that comprise the underlying index on any such day. The 6.0% per annum deduction is deducted daily, even when the underlying asset is not fully invested.

------

♦**The underlying asset may be adversely affected if later futures contracts have higher prices than an expiring futures contract included in the underlying index —** As the futures contracts included in the underlying asset come to expiration, they are replaced by futures contracts that expire three months later. This is accomplished by synthetically selling the expiring futures contract and synthetically purchasing the futures contract that expires three months from that time. This process is referred to as "rolling", and will occur over a 5-day period resulting in the underlying index exclusively referencing the second nearby futures contracts by the expiration date of the nearby futures contracts. Excluding other considerations, if the market for the futures contracts is in "contango," where the prices are higher in the distant delivery months than in the nearer delivery months, the purchase of the later futures contract would take place at a price that is higher than the price of the expiring futures contract, thereby creating a negative "roll yield." In addition, excluding other considerations, if the market for the futures contracts is in "backwardation," where the prices are lower in the distant delivery months than in the nearer delivery months, the purchase of the later futures contract would take place at a price that is lower than the price of the expiring futures contract, thereby creating a positive "roll yield." While the prices of the futures contracts cannot be predicted, historically, the futures contracts have generally experienced periods of contango. The presence of contango in the market for the futures contracts could adversely affect the level of the underlying asset and, accordingly, the market value of, and return on, your investment.

♦**There are concentration risks associated with the underlying index, and therefore, the underlying asset, that may adversely affect the market value of, and return on, your investment —** The underlying index, and therefore, the underlying asset, generally provides exposure to a single futures contract on the S&P 500<sup>®</sup> Index that trades on the Chicago Mercantile Exchange ("CME"). Accordingly, the Notes are less diversified than other funds, investment portfolios or indices investing in or tracking a broader range of products and, therefore, could experience greater volatility. You should be aware that other indices may be more diversified than the underlying asset in terms of both the number and variety of futures contracts.

♦**The underlying asset is subject to significant risks associated with futures contracts, including volatility —** The underlying asset tracks the underlying index, which seeks exposure to the returns of the futures contracts that reference the S&P 500 Index. The price of a futures contract depends not only on the price of the underlying referenced by the futures contracts, but also on a range of other factors, including but not limited to changing supply and demand relationships, interest rates, governmental and regulatory policies and the policies of the exchanges on which the futures contracts trade. In addition, the futures markets are subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets, the participation of speculators and government regulation and intervention. These factors and others can cause the prices of futures contracts to be volatile.

♦**Suspension or disruptions of market trading in futures contracts may adversely affect the market value of, and return on, your investment —** Futures markets like the CME, the market for the futures contracts, are subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets, the participation of speculators, and government regulation and intervention. In addition, futures exchanges have regulations that limit the amount of fluctuation in some futures contract prices that may occur during a single day. These limits are generally referred to as "daily price fluctuation limits" and the maximum or minimum price of a contract on any given day as a result of these limits is referred to as a "limit price." Once the limit price has been reached in a particular contract, no trades may be made at a price beyond the limit, or trading may be limited for a set period of time. Limit prices have the effect of precluding trading in a particular contract or forcing the liquidation of contracts at potentially disadvantageous times or prices. These circumstances could adversely affect the level of the underlying asset and, therefore, the market value of, and return on, your investment.

♦**The official settlement price and intraday trading prices of the relevant futures contracts may not be readily available —** The official settlement price and intraday trading prices of the futures contracts are calculated and published by the CME and are used to calculate the exposure of the underlying asset. Any disruption in trading of the futures contracts could delay the release or availability of the official settlement price and intraday trading prices and may delay or prevent the calculation of the underlying asset.

♦**Changes in the margin requirements for the futures contracts included in the underlying asset may adversely affect the market value of, and return on, your investment —** Futures exchanges require market participants to post collateral in order to open and to keep open positions in futures contracts. If an exchange changes the amount of collateral required to be posted to hold positions in the futures contracts, market participants may adjust their positions, which may affect the prices of the futures contracts. Regardless of margin requirements, because each of the underlying index and underlying asset is an excess return index, it represents an unfunded position in the futures contracts, meaning there is no benefit of any return on collateral. As a result, the level of the underlying asset may be affected, which may adversely affect the market value of, and return on, your investment.

♦**Adjustments to the underlying asset or underlying index could adversely affect the market value of, and return on, your investment —** The sponsor of the underlying asset and/or underlying index may add, delete or substitute the underlying asset components or make other methodological changes that could change the value of their levels, as the case may be, and could also discontinue or suspend calculation or publication of the underlying asset or underlying index at any time. Any of these actions could adversely affect the market value of, and return on, your investment.

♦**The underlying asset was established on September 26, 2025 and, therefore, has very limited operating history and relies on hypothetical back-tested data that does not represent actual historical data and is subject to inherent limitations —** The performances of the underlying asset and some of the component data have been retrospectively simulated for the period prior to September 26, 2025. A retrospective simulation was provided because no live data tracking the performance of the underlying asset existed at any time during the period of the retrospective simulation. The methodology and the underlying asset used for the calculation and retrospective simulation of the underlying asset has been developed with the advantage of hindsight. However, it is not possible to invest with the advantage of hindsight and, therefore, this simulated historical performance is purely theoretical and is not indicative of future performance.

♦**The hypothetical back-tested performance of the underlying asset set forth under "Hypothetical Back-Tested Data and Historical Information" herein is purely theoretical and does not represent the actual historical performance of the underlying asset and has not been verified by an independent third party —** Hypothetical back-tested performance measures have inherent limitations. Hypothetical back-tested performance is derived by means of the retroactive application of a back-tested methodology that has been designed with the benefit of hindsight and knowledge of factors that may have positively affected its performance, cannot account for all financial risk that may affect the performance of the underlying asset or the Notes and may reflect a bias toward strategies that have performed well in the past. Alternative modelling techniques might produce significantly different results and may prove to be more appropriate. Past performance, and especially hypothetical back-tested performance, is not indicative of future results. This type of information has inherent limitations and you should carefully consider these limitations before placing reliance on such information. Furthermore, any publicly available information regarding the underlying asset prior to January 3, 2007 will have been calculated using only end-of-day prices for the applicable futures contracts rather than both the end-of-day prices and the TWAP of intraday prices for the futures contracts, as described in "Annex A — Additional Information About the Solactive U.S. Large Cap Volatility Navigator 40 Index". The use of such data, which differs from both the underlying asset's methodology and all calculations on and after January 3, 2007 could impact the hypothetical back-tested levels of the underlying asset for such period.

♦**The Notes are not regulated by the Commodity Futures Trading Commission (the "CFTC") —** An investment in the Notes does not constitute either an investment in futures contracts, options on futures contracts, or commodity options and therefore you will not benefit from the regulatory protections attendant to CFTC regulated products. This means that the Notes are not traded on a regulated exchange and issued by a clearinghouse. See "-Risks Relating to Liquidity and Secondary Market Price Considerations -There may be little or no secondary market for the Notes" below. In addition, the proceeds UBS

------

receives from the sale of the Notes will not be used to purchase or sell any commodity futures contracts, options on futures contracts or options on commodities for your benefit. Therefore, an investment in the Notes does not constitute a collective investment vehicle that trades in these instruments. An investment in a collective investment vehicle that invests in these instruments is often subject to regulation as a commodity pool and its operator may be required to be registered with and regulated by the CFTC as a commodity pool operator.

***Estimated Value Considerations***

♦**The issue price you pay for the Notes will exceed their estimated initial value** — The issue price you pay for the Notes will exceed their estimated initial value as of the trade date due to the inclusion in the issue price of the underwriting compensation, hedging costs, issuance and other costs and projected profits. As of the close of the relevant markets on the trade date, we will determine the estimated initial value of the Notes by reference to our internal pricing models and it will be set forth in the final pricing supplement. The pricing models used to determine the estimated initial value of the Notes incorporate certain variables, including the level and volatility of the underlying asset and underlying constituents, any expected dividends on the underlying constituents, prevailing interest rates, the term of the Notes 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 underwriting compensation, hedging costs, issuance and other costs, projected profits and the difference in rates will reduce the economic value of the Notes to you. Due to these factors, the estimated initial value of the Notes as of the trade date will be less than the issue price you pay for the Notes.

♦**The estimated initial value is a theoretical price; the actual price at which you may be able to sell your Notes in any secondary market (if any) at any time after the trade date may differ from the estimated initial value** — The value of your Notes at any time will vary based on many factors, including the factors described above and in "— Risks Relating to Characteristics of the Underlying Asset — 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 trade date, if you attempt to sell the Notes in the secondary market, the actual value you would receive may differ, perhaps materially, from the estimated initial value of the Notes determined by reference to our internal pricing models. The estimated initial value of the Notes does not represent a minimum or maximum price at which we or any of our affiliates would be willing to purchase your Notes 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 Notes as of the trade date** — We may determine the economic terms of the Notes, as well as hedge our obligations, at least in part, prior to the trade 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 Notes cannot be determined as of the trade date and any such differential between the estimated initial value and the issue price of the Notes as of the trade date does not reflect our actual profits. Ultimately, our actual profits will be known only at the maturity of the Notes.

***Risks Relating to Liquidity and Secondary Market Price Considerations***

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

♦**The price at which UBS Securities LLC and its affiliates may offer to buy the Notes in the secondary market (if any) may be greater than UBS' valuation of the Notes at that time, greater than any other secondary market prices provided by unaffiliated dealers (if any) and, depending on your broker, greater than the valuation provided on your customer account statements** — For a limited period of time following the issuance of the Notes, UBS Securities LLC or its affiliates may offer to buy or sell such Notes at a price that exceeds (i) our valuation of the Notes at that time based on our internal pricing models, (ii) any secondary market prices provided by unaffiliated dealers (if any) and (iii) depending on your broker, the valuation provided on customer account statements. The price that UBS Securities LLC may initially offer to buy such Notes following issuance will exceed the valuations indicated by our internal pricing models due to the inclusion for a limited period of time of the aggregate value of the underwriting compensation, hedging costs, issuance costs and theoretical projected trading profit. The portion of such amounts included in our price will decline to zero on a straight line basis over a period ending no later than the date specified under "Supplemental Plan of Distribution (Conflicts of Interest); Secondary Markets (if any)." Thereafter, if UBS Securities LLC or an affiliate makes secondary markets in the Notes, it will do so at prices that reflect our estimated value determined by reference to our internal pricing models at that time. The temporary positive differential relative to our internal pricing models arises from requests from and arrangements made by UBS Securities LLC with the selling agents of structured debt securities such as the Notes. As described above, UBS Securities LLC and its affiliates intend, but are not required, to make a market for the Notes and may stop making a market at any time. The price at which UBS Securities LLC or an affiliate may make secondary markets at any time (if at all) will also reflect its then current bid-ask spread for similar sized trades of structured debt securities. UBS Securities LLC reflects this temporary positive differential on its customer statements. Investors should inquire as to the valuation provided on customer account statements provided by unaffiliated dealers.

♦**Economic and market factors affecting the terms and market price of Notes prior to maturity** — Because structured notes, including the Notes, can be thought of as having a debt component and a derivative component, factors that influence the values of debt instruments and options and other derivatives will also affect the terms and features of the Notes at issuance and the market price of the Notes prior to maturity. These factors include the level of the underlying asset and the underlying constituents; the volatility of the underlying asset and the underlying constituents; any expected dividends on the underlying constituents; the time remaining to the maturity of the Notes; interest rates in the markets; geopolitical conditions and economic, financial, political, force majeure and regulatory or judicial events; the creditworthiness of UBS; the then current bid-ask spread for the Notes and the factors discussed under "—Risks Relating to Hedging Activities and Conflicts of Interest — Potential conflicts of interest" below. These and other factors are unpredictable and interrelated and may offset or magnify each other.

♦**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 underwriting compensation, hedging costs, issuance and other costs and any projected profits are, subject to the temporary mitigating effect of UBS Securities LLC's and its affiliates' market making premium, expected to reduce the price at which you may be able to sell the Notes in any secondary market.

***Risks Relating to Hedging Activities and Conflicts of Interest***

♦**Potential UBS impact on price** — Trading or transactions by UBS or its affiliates in the underlying asset or any underlying constituent, as applicable, listed and/or over-the-counter options, futures, exchange-traded funds or other instruments with returns linked to the performance of the underlying asset or any underlying constituent, as applicable, may adversely affect the level of the underlying asset and, therefore, the market value of, and return on, the Notes.

♦**Potential conflicts of interest** — UBS and its affiliates may engage in business with any underlying constituent issuer, which may present a conflict between the interests of UBS and you, as a holder of the Notes. There are also potential conflicts of interest between you and the calculation agent, which will be an affiliate of UBS. The calculation agent will determine whether the Notes are subject to an automatic call and the payment at maturity of the Notes, if any, based on observed closing levels of the underlying asset. The calculation agent can postpone the determination of the terms of the Notes if a market

------

disruption event occurs and is continuing on the trade date, any observation date or the final valuation date. As UBS determines the economic terms of the Notes, including the call return rate, call threshold level and downside threshold, and such terms include the underwriting compensation, hedging costs, issuance and other costs and projected profits, the Notes 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. Additionally, UBS and its affiliates act in various capacities with respect to the Notes, including as a principal, agent or dealer in connection with the sale of the Notes. Such affiliates, and any other third-party dealers, will derive compensation from the distribution of the Notes and such compensation may serve as an incentive to sell these Notes instead of other investments. Furthermore, given that UBS Securities LLC and its affiliates temporarily maintain a market making premium, it may have the effect of discouraging UBS Securities LLC and its affiliates from recommending sale of your Notes in the secondary market.

♦**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, and return on, the Notes, or express opinions or provide recommendations that are inconsistent with purchasing or holding the Notes. 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 Notes and the underlying asset.

***Risks Relating to General Credit Characteristics***

♦**Credit risk of UBS** — The Notes 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 Notes, including any repayment of principal, 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 Notes. If UBS were to default on its obligations, you may not receive any amounts owed to you under the terms of the Notes and you could lose all of your initial investment.

♦**The Notes are not bank deposits** — An investment in the Notes carries risks which are very different from the risk profile of a bank deposit placed with UBS or its affiliates. The Notes 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 Notes 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 Notes) 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 Notes, 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 Notes. Prior to any debt-to-equity swap or write-off with respect to any Notes, 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 Notes; 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 Notes 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 Notes. 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 Notes, the price or value of their investment in the Notes and/or the ability of UBS to satisfy its obligations under the Notes and could lead to holders losing some or all of their investment in the Notes.

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 Notes 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 Notes 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 Notes 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 Notes are uncertain. You should consult your tax advisor about your tax situation. See "What Are the Tax Consequences of the Notes?" herein and "Material U.S. Federal Income Tax Consequences", including the section "— Securities Treated as Prepaid Derivatives or Prepaid Forwards", in the accompanying product supplement.

**Hypothetical Examples of How the Notes Might Perform**

**The below examples are based on hypothetical terms. The actual terms will be set on the trade date and will be indicated on the cover of the final pricing supplement.** 

The examples below illustrate the payment upon an automatic call or at maturity for a $1,000 Note on a hypothetical offering of the Notes, with the following assumptions (amounts may have been rounded for ease of reference):

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp; Principal Amount: | &nbsp;&nbsp;&nbsp; $1000 |
| &nbsp;&nbsp;&nbsp; Term: | &nbsp;&nbsp;&nbsp; Approximately 5 years |
| &nbsp;&nbsp;&nbsp; Call Return Rate: | &nbsp;&nbsp;&nbsp; 6.00% per annum |
| &nbsp;&nbsp;&nbsp; Observation Dates: | &nbsp;&nbsp;&nbsp; Quarterly (beginning after 12 months) |
| &nbsp;&nbsp;&nbsp; Initial Level: | &nbsp;&nbsp;&nbsp; 200.00 |
| &nbsp;&nbsp;&nbsp; Call Threshold Level: | &nbsp;&nbsp;&nbsp; 180.00 (which is equal to 90.00% of the Initial Level) |
| &nbsp;&nbsp;&nbsp; Downside Threshold: | &nbsp;&nbsp;&nbsp; 100.00 (which is equal to 50.00% of the Initial Level) |

---

**Example 1 — The Closing Level of the Underlying Asset is equal to or greater than the Call Threshold Level on the Observation Date corresponding to the first potential Call Settlement Date.**

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp; Closing Level at First Observation Date: | &nbsp;&nbsp;&nbsp; 210.00 (**equal to or greater than** Call Threshold Level, Notes are called) |
| &nbsp;&nbsp;&nbsp; Payment on Call Settlement Date: | &nbsp;&nbsp;&nbsp; $1060.00 |
| &nbsp;&nbsp;&nbsp; Total Return on the Notes: | &nbsp;&nbsp;&nbsp; 6.00% |

---

Because the Notes are subject to an automatic call following the first observation date, UBS will pay you on the call settlement date a total of $1,060.00 per Note (reflecting your principal amount plus the applicable call return), for a total return of 6.00% on the Notes. You will not receive any further payments on the Notes.

**Example 2 — The Closing Level of the Underlying Asset is equal to or greater than the Call Threshold Level on the Observation Date corresponding to the second potential Call Settlement Date.**

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp; Closing Level at First Observation Date: | &nbsp;&nbsp;&nbsp; 170.00 (**less than** Call Threshold Level, Notes not called) |
| &nbsp;&nbsp;&nbsp; Closing Level at Second Observation Date: | &nbsp;&nbsp;&nbsp; 190.00 (**equal to or greater than** Call Threshold Level, Notes are called) |
| &nbsp;&nbsp;&nbsp; Payment on Call Settlement Date: | &nbsp;&nbsp;&nbsp; $1075.00 |
| &nbsp;&nbsp;&nbsp; Total Return on the Notes: | &nbsp;&nbsp;&nbsp; 7.50% |

---

Because the Notes are subject to an automatic call following the second observation date, UBS will pay you on the call settlement date a total of $1,075.00 per Note (reflecting your principal amount plus the applicable call return), for a total return of 7.50% on the Notes. You will not receive any further payments on the Notes.

**Example 3 — The Closing Level of the Underlying Asset is equal to or greater than the Call Threshold Level on the Final Valuation Date.**

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp; Closing Level at First through Sixteenth Observation Date: | &nbsp;&nbsp;&nbsp; Various (all **less than** Call Threshold Level, Notes NOT called) |
| &nbsp;&nbsp;&nbsp; Closing Level at Final Valuation Date: | &nbsp;&nbsp;&nbsp; 200.00 (**equal to or greater than** Call Threshold Level, Notes are called) |
| &nbsp;&nbsp;&nbsp; Payment at Maturity: | &nbsp;&nbsp;&nbsp; $1300.00 |
| &nbsp;&nbsp;&nbsp; Total Return on the Notes: | &nbsp;&nbsp;&nbsp; 30.00% |

---

Because the Notes are subject to an automatic call following the final valuation date, UBS will pay you on the call settlement date a total of $1,300.00 per Note (reflecting your principal amount plus the applicable call return), for a total return of 30.00% on the Notes. You will not receive any further payments on the Notes.

------

**Example 4 — The Notes are NOT subject to an Automatic Call and the Final Level is equal to or greater than the Downside Threshold.**

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp; Closing Level at First through Sixteenth Observation Date: | &nbsp;&nbsp;&nbsp; Various (all **less than** Call Threshold Level, Notes not called) |
| &nbsp;&nbsp;&nbsp; Closing Level at Final Valuation Date: | &nbsp;&nbsp;&nbsp; 130.00 (**less than** Call Threshold Level; **equal to or greater than** Downside Threshold, Notes not called) |
| &nbsp;&nbsp;&nbsp; Payment at Maturity: | &nbsp;&nbsp;&nbsp; $1000.00 |
| &nbsp;&nbsp;&nbsp; Total Return on the Notes: | &nbsp;&nbsp;&nbsp; 0.00% |

---

Because the Notes are not subject to an automatic call and the final level is equal to or greater than the downside threshold, at maturity, UBS will pay you a total of $1,000.00 per Note (reflecting your principal amount), for a total return of 0.00% on the Notes. In this scenario, you will not receive a positive return on the Notes.

**Example 5 — The Notes are NOT subject to an Automatic Call and the Final Level is less than the Downside Threshold.**

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp; Closing Level at First through Sixteenth Observation Date: | &nbsp;&nbsp; Closing Level at First through Sixteenth Observation Date: | &nbsp;&nbsp; Various (all **less than** Call Threshold Level, Notes not called) |
| &nbsp;&nbsp; Closing Level at Final Valuation Date: | &nbsp;&nbsp; Closing Level at Final Valuation Date: | &nbsp;&nbsp; 80.00 (**less than** Call Threshold Level and Downside Threshold, Notes not called) |
| &nbsp;&nbsp; Payment at Maturity:  | &nbsp;&nbsp; $1,000 × (1 + Underlying Return) =<br> $1,000 × (1 + [-60.00%]) =<br> $400.00 | &nbsp;&nbsp; $1,000 × (1 + Underlying Return) =<br> $1,000 × (1 + [-60.00%]) =<br> $400.00 |
| &nbsp;&nbsp; Total Return on the Notes: | &nbsp;&nbsp; -60.00% | &nbsp;&nbsp; -60.00% |

---

Because the Notes are not subject to an automatic call and the final level is less than the downside threshold, at maturity you will be exposed to the negative return of the underlying asset and UBS will pay you $400.00 per Note (reflecting your payment at maturity), for a loss on the Notes of 60.00%.

**Investing in the Notes involves significant risks. The Notes differ from ordinary debt securities in that UBS is not necessarily obligated to repay the full amount of your initial investment. You will lose a significant portion or all of your investment if the Notes are not subject to an automatic call and the final level is less than the downside threshold. Specifically, if the Notes are not subject to an automatic call and the final level is less than the downside threshold, you will lose a percentage of your principal amount equal to the underlying return and, in extreme situations, you could lose all of your initial investment. Any payment on the Notes, including any repayment of principal, is subject to the creditworthiness of UBS. If UBS were to default on its obligations, you may not receive any amounts owed to you under the Notes and you could lose all of your initial investment.**

**<u>Solactive</u> <u>U.S.</u> <u>Large Cap Volatility Navigator 40 Index</u>**

The Solactive U.S. Large Cap Volatility Navigator 40 Index (the "Index") was developed by Solactive AG ("Solactive" or the "Index Sponsor"), with consultation from UBS. The Index is owned, calculated, administered, maintained and published by Solactive. The Index was established on September 26, 2025 and is reported by Bloomberg under the ticker symbol "SONAV40D Index". For additional Information about the Index and the Underlying Index, see "Annex A — Additional Information About the Solactive U.S. Large Cap Volatility Navigator 40 Index" ("Annex A").

*Overview*

The Index is rules-based and seeks to provide dynamic exposure to the Solactive Future Series 5-Day Roll United States 500 Excess Return USD Index (the "Underlying Index"), while seeking to achieve the "target volatility", and is subject to the "Decrement" (as defined below). As discussed more fully in Annex A, the Index is calculated daily in U.S. dollars on each "calculation day", which is a day that is a "futures trading day" (each as defined in Annex A) and is rebalanced daily for exposure to the Underlying Index.

The Underlying Index attempts to replicate an unfunded rolling position in the nearby quarterly CME S&P 500 E-Mini futures (the "Futures Contracts"), which reference the S&P 500<sup>®</sup> Index (the "S&P 500"), other than during the five-day rolling period which occurs prior to the expiration of the nearby Futures Contracts, when the Index measures, in part, the performance of the second nearby Futures Contracts. To achieve the target volatility, the Index can allocate a maximum exposure to the Underlying Index of up to 500% and, conversely, can allocate as little as 0%. The S&P 500 consists of stocks of 500 companies selected to provide a performance benchmark for the U.S. equity markets. For more information about the Futures Contracts and the S&P 500, see Annex A included at the end of this document.

*Decrement Deduction*

The Index is subject to a 6.0% per annum daily deduction (the "Decrement"), regardless of whether the Index appreciates or depreciates. The Decrement is applied daily at the rate of 6.0% per annum, even when the Index is not fully invested in the Underlying Index. The 6.0% per annum daily deduction will offset any appreciation of the Underlying Index, will heighten any depreciation of the Underlying Index and will generally be a drag on the performance of the Index. The Index will underperform a similar index which does not include such a decrement feature.

*Target Volatility*

On each daily rebalancing day, the Index's exposure to the Underlying Index is based on the realized volatility of the Futures Contracts, which is a measurement of the degree of movement in the price of such asset(s) over a specified period. Specifically, the Index's exposure is set equal to (a) the 40% volatility target (the "Target Volatility") divided by (b) the greater of the 5-day or 40-day realized volatility of the Futures Contracts, subject to a maximum exposure of 500%. For example, if the 5-day and 40-day realized volatility of the Futures Contracts were equal to 15% and 20%, respectively, the Index's exposure to the Underlying Index would equal 200% (or 40% / 20%). Conversely, if the 5-day and 40-day realized volatility of the Futures Contracts equaled 50% and 40%, respectively, the Index's exposure to the Underlying Index would equal 80% (or 40% / 50%). The Index's exposure to the Underlying Index will be greater than 100% when the greater of the 5-day and 40-day realized volatility of the Futures Contracts is below 40%, and will be less than 100% when the greater of the 5-day and 40-day realized volatility of the Futures Contracts is above 40%. As set out more fully in Annex A, the 5-day and 40-day realized volatility are calculated based on the settlement prices of the relevant Futures Contracts over the preceding 4 and 39 days, and the time-weighted average prices (or "TWAP") of the relevant Futures Contracts on such relevant calculation day, determined intraday prior to the publishing of the official settlement price for the Futures Contracts on that day.

In general, the Index's target volatility feature is intended to result in the volatility of the Index being more stable over time relative to an otherwise comparable index without a volatility target feature. No assurance can be provided that the volatility of the Index will be stable at any time, or that the Index will succeed in seeking to achieve its target volatility.

*The Underlying Index*

The investment objective of the Underlying Index is to provide investment results that, before expenses, correspond generally to the price and yield performance of the S&P 500. To achieve this, the Underlying Index measures the performance of the nearby Futures Contracts, other than during the rolling period, which occurs prior to the expiration of the nearby Futures Contracts, when it also measures, in part, the performance of the second nearby Futures Contract. The Futures Contracts are rolled quarterly in March, June, September and December over a 5 day rolling period, as described more fully in Annex A, resulting in the Underlying Index tracking only the second nearby Futures Contracts on the expiration day of the nearby Futures Contracts. The Underlying Index is an "excess return" index and not a "total return" index, which means it measures the returns accrued from investing in uncollateralized futures contracts. As a result, the level of the Underlying Index (and, therefore, the Index) does not benefit from any collateral return on any futures contracts or any dividends or other distributions on any index constituents of the S&P 500.

**The Index is subject to risks associated with the use of significant leverage. In addition, the Index may be significantly uninvested on any given day, and, in that case, will realize only a portion of any gains due to appreciation of the Underlying Index (and the Futures Contracts) on that day. The index is deducted daily at a rate of 6.0% per annum, even when the Index is not fully invested. Further, because the Index and the Underlying Index are "excess return" indices, they are based on an unfunded position, meaning you will not receive any interest or benefit from any collateral return, irrespective of whether the Index is leveraged or unfunded.**

**No assurance can be given that the investment strategy used to construct the Index will achieve its intended results or that the Index will be successful or will outperform any alternative index or strategy that might reference the Futures Contracts.**

For additional information about the Index, the Underlying Index, the Futures Contracts and the S&P 500, see Annex A included at the end of this document.

**<u>Hypothetical Back-Tested Data and</u> <u>Historical Information</u>**

The graph below illustrates the hypothetical back-tested performance of the Index from January 1, 2015 through September 25, 2025 and the actual historical performance of the Index from September 26, 2025 through October 30, 2025, based on the daily closing levels as reported by Bloomberg, without independent verification. The data for the hypothetical back-tested performance of the Index set forth in the following graph are purely theoretical and do not represent the actual historical performance of the Index. See "Key Risks - Risks Relating to Characteristics of the Underlying Asset - The hypothetical back-tested performance of the underlying asset set forth under "Hypothetical Back-Tested Data and Historical Information" herein is purely theoretical and does not represent the actual historical performance of the underlying asset and has not been verified by an independent third party" above. UBS has not conducted any independent review or due diligence of any publicly available information obtained from Bloomberg. The closing level of the Index on October 30, 2025 was 308.04 (the "hypothetical initial level"). The dotted lines respectively represents a hypothetical call threshold level of 277.24, which is equal to 90.00% of the hypothetical initial level and a hypothetical downside threshold of 154.02, which is equal to 50.00% of the hypothetical initial level. The actual initial level, call threshold level and downside threshold level will be determined on the trade date. ***Past performance and hypothetical back-tested performance of the underlying asset is not indicative of the future performance of the underlying asset during the term of the Notes.***

What Are the Tax Consequences of the Notes?

**The U.S. federal income tax consequences of your investment in the Notes 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 Notes. 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 Notes, and the following discussion is not binding on the IRS.**

*U.S. Tax Treatment.* Pursuant to the terms of the Notes, 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 Notes as prepaid derivative contracts with respect to the underlying asset. If your Notes are so treated, you should generally recognize gain or loss upon the taxable disposition of your Notes in an amount equal to the difference between the amount you receive at such time and the amount you paid for your Notes. Such gain or loss should generally be long-term capital gain or loss if you have held your Notes for more than one year (otherwise such gain or loss should be short-term capital gain or loss if held for one year or less). 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 Notes in the manner described above. However, because there is no authority that specifically addresses the tax treatment of the Notes, it is possible that your Notes 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 Notes 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.**

Except to the extent otherwise required by law, UBS intends to treat your Notes for U.S. federal income tax purposes in accordance with the treatment described above and under "Material U.S. Federal Income Tax Consequences — Securities Treated as Prepaid Derivatives or Prepaid Forwards" in the accompanying product supplement unless and until such time as the IRS and the Treasury determine that some other treatment is more appropriate.

*Notice 2008-2.* In 2007, the IRS released a notice that may affect the taxation of holders of the Notes. According to Notice 2008-2, the IRS and the Treasury are actively considering whether the holder of an instrument such as the Notes 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 Notes 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 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 Notes, 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 dollar 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 as to the consequences of the 3.8% Medicare tax.

*Specified Foreign Financial Assets.* U.S. holders may be subject to reporting obligations with respect to their Notes if they do not hold their Notes in an account maintained by a financial institution and the aggregate value of their Notes and certain other "specified foreign financial assets" (applying certain attribution rules) exceeds an applicable threshold. Significant penalties can apply if a U.S. holder is required to disclose its Notes and fails to do so.

*Non-U.S. Holders.* Subject to Section 871(m) of the Code and "FATCA", discussed below, if you are a non-U.S. holder you should generally not be subject to U.S. withholding tax with respect to payments on your Notes or to generally applicable information reporting and backup withholding requirements with respect to payments on your Notes if you comply with certain certification and identification requirements as to your non-U.S. status (by providing us (and/or the applicable withholding agent) with a fully completed and duly executed applicable IRS Form W-8). Subject to Section 897 of the Code, discussed above, and Section 871(m) of the Code, discussed below, gain realized from the taxable disposition of a Note 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 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, 2027.

Based on our determination that the Notes are not "delta-one" with respect to the underlying asset or any underlying constituents, our special U.S. tax counsel is of the opinion that the Notes 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 Notes 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 Notes could be deemed to be reissued for tax purposes upon the occurrence of certain events affecting the underlying asset, the underlying constituents or your Notes, and following such occurrence your Notes 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 Notes under these rules if a non-U.S. holder enters, or has entered, into certain other transactions in respect of the underlying asset, any underlying constituents or the Notes. A non-U.S. holder that enters, or has entered, into other transactions in respect of the underlying asset, any underlying constituents or the Notes should consult its tax advisor regarding the application of Section 871(m) of the Code to its Notes in the context of its other transactions.

**Because of the uncertainty regarding the application of the 30% withholding tax on dividend equivalents to the Notes, 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 Notes.**

*Foreign Account Tax Compliance Act.* The Foreign Account Tax Compliance Act ("FATCA") was enacted on March 18, 2010, and imposes a 30% U.S. withholding tax on "withholdable payments" (i.e., certain U.S.-source payments, including interest (and original issue discount), dividends, other fixed or determinable annual or periodical gain, profits, and income, and on the gross proceeds from a disposition of property of a type which can produce U.S.-source interest or dividends) and "passthru payments" (i.e., certain payments attributable to withholdable payments) made to certain foreign financial institutions (and certain of their affiliates) unless the payee foreign financial institution agrees (or is required), among other things, to disclose the identity of any U.S. individual with an account of the institution (or the relevant affiliate) and to annually report certain information about such account. FATCA also requires withholding agents making withholdable payments to certain foreign entities that do not disclose the name, address, and taxpayer identification number of any substantial U.S. owners (or do not certify that they do not have any substantial U.S. owners) to withhold tax at a rate of 30%. Under certain circumstances, a holder may be eligible for refunds or credits of such taxes.

Pursuant to final and temporary Treasury regulations and other IRS guidance, the withholding and reporting requirements under FATCA will generally apply to certain "withholdable payments", will not apply to gross proceeds on a sale or disposition, and will apply to certain foreign passthru payments only to the extent that such payments are made after the date that is two years after final regulations defining the term "foreign passthru payment" are published. If withholding is required, we (or the applicable paying agent) will not be required to pay additional amounts with respect to the amounts so withheld. Foreign financial institutions and non-financial foreign entities located in jurisdictions that have an intergovernmental agreement with the U.S. governing FATCA may be subject to different rules.

Investors should consult their tax advisors about the application of FATCA, in particular if they may be classified as financial institutions (or if they hold their Notes through a foreign entity) under the FATCA rules.

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

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 Notes 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 Notes. You are urged to consult your tax advisor regarding the possible changes in law and their possible impact on the tax treatment of your Notes.

**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 Notes arising under the laws of any state, local, non-U.S. or other taxing jurisdiction.**

------

**Supplemental Plan of Distribution (Conflicts of Interest); Secondary Markets (if any)**

We will agree to sell to UBS Securities LLC and UBS Securities LLC will agree to purchase, all of the Notes at the issue price to the public less the underwriting discount indicated on the cover hereof. UBS Securities LLC intends to either resell the Notes to one or more third-party dealers at a discount from the issue price to the public equal to the underwriting discount indicated on the cover hereof or to offer the Notes directly to investors at the issue price to the public. Certain of such third-party dealers may resell the Notes to other securities dealers at the issue price to the public less an underwriting discount of up to the underwriting discount indicated on the cover hereof. Certain unaffiliated registered investment advisers or fee-based advisory accounts may purchase Notes from a third-party dealer at a purchase price of at least $990.00 per Note, and such third-party dealer, with respect to such sales, may forgo some or all of the underwriting discount. UBS Securities LLC may also pay another unaffiliated dealer a marketing fee per Note in the amount indicated on the cover hereof with respect to some or all of the Notes in connection with its marketing efforts. The marketing fee will be deducted from amounts remitted to UBS. Additionally, we or one of our affiliates may pay a fee to an unaffiliated broker-dealer for providing certain electronic platform services with respect to this offering.

**Conflicts of Interest** —UBS Securities LLC is an affiliate of UBS and, as such, has a "conflict of interest" in this offering within the meaning of Financial Industry Regulatory Authority, Inc. ("FINRA") Rule 5121. In addition, UBS will receive the net proceeds (excluding the underwriting compensation) from the initial public offering of the Notes, thus creating an additional conflict of interest within the meaning of FINRA Rule 5121. Consequently, the offering is being conducted in compliance with the provisions of FINRA Rule 5121. UBS Securities LLC is not permitted to sell Notes in this offering to an account over which it exercises discretionary authority without the prior specific written approval of the account holder.

**UBS Securities LLC and its affiliates may offer to buy or sell the Notes in the secondary market (if any) at prices greater than UBS' internal valuation** — The value of the Notes at any time will vary based on many factors that cannot be predicted. However, the price (not including UBS Securities LLC's or any affiliates' customary bid-ask spreads) at which UBS Securities LLC or any affiliate would offer to buy or sell the Notes immediately after the trade date in the secondary market is expected to exceed the estimated initial value of the Notes as determined by reference to our internal pricing models. The amount of the excess will decline to zero on a straight line basis over a period ending no later than 6 months after the trade date, provided that UBS Securities LLC may shorten the period based on various factors, including the magnitude of purchases and other negotiated provisions with selling agents. Notwithstanding the foregoing, UBS Securities LLC and its affiliates intend, but are not required to make a market for the Notes and may stop making a market at any time. For more information about secondary market offers and the estimated initial value of the Notes, see "Key Risks — Estimated Value Considerations" and "— Risks Relating to Liquidity and Secondary Market Price Considerations" herein.

**Prohibition on Sales to EEA Retail Investors** — The Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (the "EEA"). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, "MiFID II"); or (ii) a customer within the meaning of Directive (EU) 2016/97, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Regulation (EU) 2017/1129, as amended. Consequently no key information document required by Regulation (EU) No 1286/2014 (the "EU PRIIPs Regulation") for offering or selling the Notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the EEA may be unlawful under the EU PRIIPs Regulation.

**Prohibition on Sales to UK Retail Investors** — The Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom ("UK"). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (the "EUWA"); (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (the "FSMA") and any rules or regulations made under the FSMA to implement Directive (EU) 2016/97, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA. Consequently no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law by virtue of the EUWA (the "UK PRIIPs Regulation") for offering or selling the Notes or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.

**<u>Annex A</u>**

**Additional Information About the Solactive U.S. Large Cap Volatility Navigator 40 Index**

**<u>Overview</u>**

The Solactive U.S. Large Cap Volatility Navigator 40 Index (the "Index") is a rules-based index that was developed by Solactive AG ("Solactive"), with consultation from UBS, and was established on September 26, 2025. The Index employs a dynamic rules-based strategy that seeks to provide exposure to the Solactive Future Series 5-Day Roll United States 500 Excess Return USD Index (the "Underlying Index"), an unfunded rolling futures index that is designed to measure the performance of the nearby quarterly CME S&P 500 E-Mini futures (the "Futures Contracts"), which reference the S&P 500<sup>®</sup> Index (the "S&P 500"). In addition, the strategy applies an overall volatility-targeting feature upon the resulting portfolio, targeting a level of 40% volatility with a maximum exposure to the rolling futures index of 500% and a minimum exposure of 0%. The Index is subject to a 6.0% per annum daily deduction or decrement.

**The Index is subject to risks associated with the use of significant leverage. In addition, the Index may be significantly uninvested on any given day, and, in that case, will realize only a portion of any gains due to appreciation of the Futures Contracts on that day. The Index is deducted daily at a rate of 6.0% per annum, even when the Index is not fully invested. Further, because the Index and the Underlying Index are "excess return" indices, they are based on an unfunded position, meaning you will not receive any interest or benefit from any collateral return, irrespective of whether the Index is leveraged or unfunded.**

**No assurance can be given that the investment strategy used to construct the Index will achieve its intended results or that the Index will be successful or will outperform any alternative index or strategy that might reference the Futures Contracts.**

**<u>Calculation of the Index</u>**

The Index is calculated daily in U.S. dollars on each "Calculation Day", which is a day that is a Futures Trading Day (as defined below) and is rebalanced daily for exposure (each such Calculation Day may also be referred to as a "Rebalancing Day").

Solactive will determine the level of the Index according to the following methodology and the level of the Index will be rounded to two (2) decimal places for publication:

![](image3.gif)

**Where:**

: The level of the Index as of the Calculation Day t.

: The level of the Index as of the Calculation Day t-1.

: The exposure of the Index to the Underlying index as of the Calculation Day t-1.

: The level calculated by Solactive at the close of business (the "Closing Level") of the Underlying Index as of the Calculation Day t.

: The Closing Level of the Underlying Index as of the Calculation Day t-1.

: The number of calendar days between Calculation Day t (including) and Calculation Day t-1 (excluding).

: The decrement percent of 6.0% per annum, deducted daily.

Pursuant to the above, the exposure of the Index to the Underlying Index as of Calculation Day *t*, which is rebalanced daily, is calculated according to the following:

![](image11.gif)

**Where**:

*round*: Rounding function to the number of decimals specified (6).

: The maximum exposure, which equals 500%.

: The level of the target volatility of 40%.

: The realized volatility as of Calculation Day t is calculated according to the following:

![](image15.gif)

*Where*:

: The 5 day (4 returns) volatility as of Calculation Day t.

: The 40 day (39 returns) volatility as of Calculation Day t.

The n-day volatility (where n = 5 or n = 40) is calculated according to:

![](image18.gif)

*Where*:

: EOD/TWAP Return as the Calculation Day which is i Calculation Days prior to Calculation Day t.

: EOD/EOD Return as the Calculation Day which is i Calculation Days prior to Calculation Day t.

------

: The average of the last n-days of returns, including t.

![](image22.gif)

The "TWAP Level" of the Underlying Index is calculated as follows:

Each quote tick n (and total of N ticks), which arrive between the Time Window Start, meaning 12:45 p.m. America/Chicago on CME (as defined below) regular trading days and 9:45 a.m. America/Chicago on CME E-mini S&P 500 futures early close days, and Time Window End, meaning 1:00 p.m. America/Chicago on CME regular trading days and 10:00 a.m. America/Chicago on CME E-mini S&P 500 futures early close days, will be used in calculation of the TWAP on Calculation Day t.

The TWAP, , and as of Calculation Day t of Future Contract c is calculated according to the following formula:

![](image25.gif)

Where:

: is the quoted buy price received last in the n-th second on or after the Time Window Start of Future Contract c on Calculation Day .

: is the quoted sell price received last in the n-th second on or after the Time Window Start of Future Contract c on Calculation Day .

Further the as of Calculation Day t of the Future Contract c is calculated according to the following formula:

![](image30.gif)

Finally, and EOD/TWAP Return and EOD/EOD Return as of Calculation Day t of is calculated according to the following formula:

![](image33.gif)

and

![](image34.gif)

With

being the Weight (as defined below) of the Future Contract c on Calculation Day , the Settlement Price of Future Contract c on Calculation Day , and

the Settlement Price of Future Contract c on Calculation Day *t-1*

<u>Underlying Index</u>

The Underlying Index is also managed, maintained and calculated by Solactive and measures the performance of the nearby Futures Contracts, other than during the rolling period, when it also measures the performance of the second nearby Futures Contract. The relevant Futures Contracts are rolled quarterly in March, June, September and December over a five day roll period beginning on the seventh (7th) Futures Trading Day preceding the last Futures Trading Day of the relevant futures contract. A "Futures Trading Day" is a day on which the Chicago Mercantile Exchange ("CME") is scheduled to be open for trading.

**<u>Futures Contracts</u>**

CME S&P 500 E-Mini futures (the "Futures Contracts") are U.S. dollar-denominated futures contracts, based on the S&P 500<sup>®</sup> Index, traded on the CME, representing a contract unit of $50 multiplied by the S&P 500<sup>®</sup> Index, measured in cents per index point.

Futures Contracts listed for the nearest nine quarters, for each March, June, September and December, and the nearest three Decembers are available for trading. Trading of the Futures Contracts terminates on the third Friday of the contract month.

The daily settlement prices of the Futures Contracts are based on trading activity in the relevant contract (and in the case of a lead month also being the expiry month, together with trading activity on lead month-second month spread contracts) on the CME during a specified settlement period. The final settlement price of the Futures Contracts is based on the opening prices of the component stocks in the S&P 500<sup>®</sup> Index, determined on the third Friday of the contract month.

All disclosures contained in this document regarding the Futures Contracts are derived from publicly available information. Information from outside sources is not incorporated by reference in, and should not be considered part of, this document or any document incorporated herein by reference.
