Investment Timeline

Investing in the Securities involves significant risks. You may lose a significant portion or all of your initial investment. Specifically, if the final level of any underlying asset is less than its downside threshold, you will lose a percentage of your principal amount equal to the underlying return of the least performing underlying asset and, in extreme situations, you could lose all of your initial investment. You will be exposed to the market risk of each underlying asset on the final valuation date and any decline in the level of one underlying asset may negatively affect your return and will not be offset or mitigated by a lesser decline or any potential increase in the level of any other underlying asset. Any payment on the Securities, 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 Securities and you could lose all of your initial investment.

Key Risks

An investment in the Securities involves significant risks. Investing in the Securities is not equivalent to a hypothetical investment in the least performing underlying asset. Some of the key risks that apply to the Securities are summarized below, but we urge you to read the more detailed explanation of risks relating to the Securities 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 Securities.

Risks Relating to Return Characteristics

♦Risk of loss at maturity — The Securities differ from ordinary debt securities in that UBS will not necessarily repay the principal amount of the Securities. If the least performing underlying return is negative and the final level of the least performing underlying asset is less than its downside threshold, you will lose a percentage of your principal amount equal to the least performing underlying return and, in extreme situations, you could lose all of your initial investment.

♦The contingent repayment of principal applies only if you hold your Securities to maturity — You should be willing to hold your Securities to maturity. The stated payout by the issuer is available only if you hold your Securities to maturity. If you are able to sell your Securities prior to maturity in the secondary market, you may have to sell them at a loss relative to your initial investment even if the level of each underlying asset at such time is equal to or greater than its downside threshold.

♦The upside gearing applies only at maturity — You should be willing to hold your Securities to maturity. If you are able to sell your Securities prior to maturity in the secondary market, the price you receive will likely not reflect the full economic value of the upside gearing and the percentage return you realize may be less than the then-current least performing underlying return multiplied by the upside gearing, even if such return is positive. You can receive the full benefit of the upside gearing only if you hold your Securities to maturity.

♦No interest payments — UBS will not pay any interest with respect to the Securities.

♦Greater expected volatility generally indicates an increased risk of loss at maturity — “Volatility” refers to the frequency and magnitude of changes in the level of each underlying asset. The greater the expected volatility of each of the underlying assets as of the trade date, the greater the expectation is as of that date that the final level of an underlying asset could be less than its downside threshold and, as a consequence, indicates an increased risk of loss. However, the underlying assets’ volatility can change significantly over the term of the Securities, and relatively lower downside thresholds may not necessarily indicate that the Securities have a greater likelihood of a return of principal at maturity. You should be willing to accept the downside market risk of the least performing underlying asset and the potential to lose a significant portion or all of your initial investment.

♦Owning the Securities is not the same as owning the underlying constituents — The return on your Securities may not reflect the return you would realize if you actually owned the underlying constituents. Rather, it will be contingent upon the performance of each underlying asset. Unlike an instrument with a return linked to a basket of indices, common stocks or other underlying securities, in which risk is mitigated and diversified among all of the components of the basket, you will be exposed equally to the risks related to each underlying asset. Poor performance by any underlying asset over the term of the Securities will negatively affect your return and will not be offset or mitigated by a positive performance by any other underlying asset. In addition, as an owner of the Securities, you will not receive or be entitled to receive any dividend payments or other distributions on any underlying constituents during the term of the Securities, and any such dividends or distributions will not be factored into the calculation of the payment at maturity on your Securities. Similarly, you will not have voting rights or any other rights of a holder of any underlying constituents.

Risks Relating to Characteristics of the Underlying Assets

♦You are exposed to the market risk of each underlying asset — Your return on the Securities is not linked to a basket consisting of the underlying assets. Rather, it will be contingent upon the performance of each individual underlying asset. Unlike an instrument with a return linked to a basket of assets, in which risk is mitigated and diversified among all of the components of the basket, you will be exposed equally to the risks related to each underlying asset. Poor performance by any one of the underlying assets over the term of the Securities will negatively affect your return and will not be offset or mitigated by a positive performance by any other underlying asset. For instance, you will receive a negative return on your Securities if the final level of any underlying asset is less than its downside threshold, even if the underlying return of each other underlying asset is positive or has not declined as much. Accordingly, your investment is subject to the market risk of each underlying asset.

♦Because the Securities are linked to the least performing underlying asset, you are exposed to a greater risk of losing a significant portion or all of your initial investment at maturity than if the Securities were linked to a single underlying asset or fewer underlying assets — The risk that you will lose a significant portion or all of your initial investment in the Securities is greater if you invest in the Securities than the risk of investing in substantially similar securities that are linked to the performance of only one underlying asset or to fewer underlying assets. With more underlying assets, it is more likely that the final level of an underlying asset will be less than its downside threshold than if the Securities were linked to a single underlying asset or fewer underlying assets. In addition, the lower the correlation between a pair of underlying assets, the greater the likelihood that one of the underlying assets will decline to a final level that is less than its downside threshold. Although the correlation of the underlying assets’ performance may change over the term of the Securities, the economic terms of the Securities, including the downside thresholds and upside gearing, are determined, in part, based on the correlation of the underlying assets’ performance calculated using our internal models at the time when the terms of the Securities are finalized. All things being equal, lower downside thresholds and a higher upside gearing are generally associated with lower correlation of the underlying assets. Therefore, if the performance of a pair of underlying assets is not correlated to each other or is negatively correlated, the risk that the final level of any underlying asset will be less than its downside threshold is even greater despite lower downside thresholds or a higher upside gearing. With three underlying assets, it is more likely that the performance of one pair of underlying assets will not be correlated, or will be negatively correlated. Therefore, it is more likely that the final level of any underlying asset will be less than its downside threshold and that you will lose a significant portion or all of your initial investment at maturity.

♦Market risk — The return on the Securities, which may be negative, is directly linked to the performance of the underlying assets and indirectly linked to the performance of the underlying constituents and their issuers (the “underlying constituent issuers”). The levels of the underlying assets can rise or fall sharply due to factors specific to each underlying asset or its 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 Securities, should conduct your own investigation into the underlying assets and underlying constituents.

♦There can be no assurance that the investment view implicit in the Securities will be successful — It is impossible to predict whether and the extent to which the levels of the underlying assets will rise or fall and there can be no assurance that the final level of each underlying asset will be equal to or greater than its initial level or downside threshold. The levels of the underlying assets 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 each underlying asset in general and its underlying constituents in particular, and the risk of losing a significant portion or all of your initial investment.

♦Changes affecting an underlying asset, including regulatory changes, could have an adverse effect on the market value of, and return on, your Securities — The policies of any index sponsor as specified under “Information About the Underlying Assets” (each, an “index sponsor”), concerning

4

additions, deletions and substitutions of the underlying constituents and the manner in which such index sponsor takes account of certain changes affecting those underlying constituents may adversely affect the level of the applicable underlying asset. The policies of an index sponsor with respect to the calculation of the applicable underlying asset could also adversely affect the level of such underlying asset. An index sponsor may discontinue or suspend calculation or dissemination of the applicable underlying asset. Further, indices like each 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 applicable underlying asset) or the administrator (its 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 the trading day immediately prior 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 Securities.

♦UBS cannot control actions by the index sponsors and the index sponsors have no obligation to consider your interests — UBS and its affiliates are not affiliated with the index sponsors and have no ability to control or predict their actions, including any errors in or discontinuation of public disclosure regarding methods or policies relating to the calculation of the underlying assets. The index sponsors are not involved in the Securities offering in any way and has no obligation to consider your interest as an owner of the Securities in taking any actions that might affect the market value of, and return on, your Securities.

♦The Dow Jones Industrial Average®, Russell 2000® Index and S&P 500® Equal Weight Index reflects price return, not total return — The return on the Securities is based on the performance of the Dow Jones Industrial Average®, Russell 2000® Index and S&P 500® Equal Weight Index, which reflects the changes in the market prices of its underlying constituents. The Dow Jones Industrial Average®, Russell 2000® Index and S&P 500® Equal Weight Index is not a “total return” index or strategy, which, in addition to reflecting those price returns, would also reflect any dividends paid on its underlying constituents. The return on the Securities will not include such a total return feature or dividend component.

♦The Securities are subject to small-capitalization stock risks — The Securities are subject to risks associated with small-capitalization companies because the Russell 2000® Index is comprised of stocks of companies that may be considered small-capitalization companies. These companies often have greater stock price volatility, lower trading volume and less liquidity than large-capitalization companies and therefore such index may be more volatile than an index in which a greater percentage of its constituents are issued by large-capitalization companies. Stock prices of small-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business and economic developments, and the stocks of small-capitalization companies may be thinly traded. In addition, small-capitalization companies are typically less stable financially than large-capitalization companies and may depend on a small number of key personnel, making them more vulnerable to loss of personnel. Small-capitalization companies are often given less analyst coverage and may be in early, and less predictable, periods of their corporate existences. Such companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and less competitive strengths than large-capitalization companies and are more susceptible to adverse developments related to their products.

♦The S&P 500® Equal Weight Index may underperform the S&P 500® Index — The S&P 500® Equal Weight Index is composed of the same underlying constituents as the S&P 500® Index, but weights those underlying constituents equally (as rebalanced each quarter) rather than based on market capitalization as in the S&P 500® Index. As a result, the companies with the largest market capitalizations will have a smaller impact on the performance of the S&P 500® Equal Weight Index than on the performance of the S&P 500® Index. If larger market capitalization companies outperform smaller market capitalization companies, then the S&P 500® Equal Weight Index will underperform the S&P 500® Index, perhaps significantly.

Estimated Value Considerations

♦The issue price you pay for the Securities will exceed their estimated initial value — The issue price you pay for the Securities 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 Securities 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 Securities incorporate certain variables, including the levels and volatility of the underlying assets and underlying constituents, any expected dividends on the underlying constituents, the correlation of the underlying assets, prevailing interest rates, the term of the Securities 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 Securities to you. Due to these factors, the estimated initial value of the Securities as of the trade date will be less than the issue price you pay for the Securities.

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

Risks Relating to Liquidity and Secondary Market Price Considerations

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

♦The price at which UBS Securities LLC and its affiliates may offer to buy the Securities in the secondary market (if any) may be greater than UBS’ valuation of the Securities 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 Securities, UBS Securities LLC or its affiliates may offer to buy or sell such Securities at a price that exceeds (i) our valuation of the Securities 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 Securities 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 discount, 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 Securities, 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 Securities. As described above, UBS Securities LLC and its affiliates intend, but are not required, to make a market for the Securities 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 Securities prior to maturity — Because structured notes, including the Securities, 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 Securities at issuance and the market price of the Securities prior to maturity. These factors include the levels of the underlying assets and the underlying constituents; the volatility of the underlying assets and the underlying constituents; any expected dividends on the underlying constituents; the correlation of the underlying assets; the time remaining to the maturity of the Securities; 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 Securities 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 Securities 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 any underlying asset or 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 any underlying asset or underlying constituent, as applicable, may adversely affect the levels of the underlying assets and, therefore, the market value of, and return on, the Securities.

♦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 Securities. 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 the payment at maturity of the Securities based on the final levels of the underlying assets. The calculation agent can postpone the determination of the terms of the Securities if a market disruption event occurs and is continuing on the trade date or the final valuation date. As UBS determines the economic terms of the Securities, including the downside thresholds and upside gearing, and such terms include the underwriting compensation, hedging costs, issuance and other costs and projected profits, the Securities 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 Securities, including as a principal, agent or dealer in connection with the sale of the Securities. Such affiliates, and any other third-party dealers, will derive compensation from the distribution of the Securities and such compensation may serve as an incentive to sell these Securities 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 Securities 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 Securities, or express opinions or provide recommendations that are inconsistent with purchasing or holding the Securities. 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 Securities and the underlying assets.

Risks Relating to General Credit Characteristics

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

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

6

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

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

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

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

Risks Relating to U.S. Federal Income Taxation

♦Uncertain tax treatment — Significant aspects of the tax treatment of the Securities are uncertain. You should consult your tax advisor about your tax situation. See “What Are the Tax Consequences of the Securities?” 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 and Return Table of the Securities at Maturity

The below examples and table 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 and table below illustrate the payment at maturity for a $1,000 Security on a hypothetical offering of the Securities, with the following assumptions (amounts may have been rounded for ease of reference):

Example 1 — Underlying Asset A is the Least Performing Underlying Asset and its Final Level is 45,150.00, an increase of 5.00% from its Initial Level of 43,000.00.

Because the least performing underlying return is positive, the payment at maturity per Security will be calculated as follows:

$1,000 × (1 + Least Performing Underlying Return × Upside Gearing)
= $1,000 × (1 + 5.00% × 1.631)
= $1,000 × (1 + 8.155%)
= $1,081.55 per Security (8.155% total return).

Example 2 — Underlying Asset B is the Least Performing Underlying Asset and its Final Level is 1,900.00, a decrease of 5.00% from its Initial Level of 2,000.00.

Because the least performing underlying return is zero or negative and the final level of the least performing underlying asset is equal to or greater than its downside threshold, the payment at maturity per Security will be equal to the principal amount of $1,000 (0.00% total return).

Example 3 — Underlying Asset A is the Least Performing Underlying Asset and its Final Level is 17,200.00, a decrease of 60.00% from its Initial Level of 43,000.00.

Because the least performing underlying return is negative and the final level of the least performing underlying asset is less than its downside threshold, the payment at maturity per Security will be less than the principal amount, if anything, calculated as follows:

$1,000 × (1 + Least Performing Underlying Return)
= $1,000 × (1 + -60.00%)
= $400.00 per Security (60.00% loss).

In this scenario, you will suffer a percentage loss on your initial investment equal to the underlying return of the least performing underlying asset, regardless of the underlying return of any other underlying asset and, in extreme situations, you could lose all of your initial investment.

(1) Assumes Underlying Asset A is the Least Performing Underlying Asset.

We make no representation or warranty as to which of the underlying assets will be the least performing underlying asset for the purposes of calculating your actual payment at maturity.

Investing in the Securities involves significant risks. You may lose a significant portion or all of your initial investment. Specifically, if the final level of any underlying asset is less than its downside threshold, you will lose a percentage of your principal amount equal to the underlying return of the least performing underlying asset and, in extreme situations, you could lose all of your initial investment. You will be exposed to the market risk of each underlying asset on the final valuation date and any decline in the level of one underlying asset may negatively affect your return and will not be offset or mitigated by a lesser decline or any potential increase in the level of any other underlying asset. Any payment on the Securities, 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 amount owed to you under the Securities and you could lose all of your initial investment.

Information About the Underlying Assets

All disclosures contained in this document regarding each underlying asset are derived from publicly available information. UBS has not conducted any independent review or due diligence of any publicly available information with respect to any underlying asset. You should make your own investigation into each underlying asset.

Included below is a brief description of each underlying asset. This information has been obtained from publicly available sources. Set forth below for each underlying asset is a graph that illustrates the past performance for such underlying asset. The information given below is for the period indicated. We obtained the past performance information set forth below from Bloomberg Professional® service (“Bloomberg”) without independent verification. You should not take the historical levels of any underlying asset as an indication of future performance.

While INDU component selection is not governed by quantitative rules, the Averages Committee selects the INDU components based on the company's reputation, growth and interest to investors. Maintaining adequate sector representation is also a consideration in the selection process. INDU covers all industries with the exception of transportation and utilities. The Averages Committee may revise index policy covering rules for selecting companies, treatment of dividends, share counts or other matters.

Russell 2000® Index

We have derived all information regarding the Russell 2000® Index (“RTY”) contained in this document, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. Such information reflects the policies of, and is subject to change by the Frank Russell Company (the “index sponsor” or “FTSE Russell”).

RTY is published by FTSE Russell, but FTSE Russell has no obligation to continue to publish RTY, and may discontinue publication of RTY at any time. RTY is determined, comprised and calculated by FTSE Russell without regard to this instrument.

As discussed more fully in the index supplement under the heading “Underlying Indices and Underlying Index Publishers – Russell 2000 Index,” RTY measures the composite price performance of the smallest 2,000 companies included in the Russell 3000® Index. The Russell 3000® Index is composed of the 3,000 largest United States companies by market capitalization and represents approximately 98% of the market capitalization of the United States equity market. Select information regarding top constituents and industry and/or sector weightings may be made available by the index sponsor on its website. RTY’s value is calculated by adding the market values of the underlying constituents and then dividing the derived total market capitalization by the “adjusted” capitalization of RTY on the base date of December 31, 1986.

S&P 500® Equal Weight Index

We have derived all information regarding the S&P 500® Equal Weight Index (“SPW”) contained in this document, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. Such information reflects the policies of, and is subject to change by S&P Dow Jones Indices LLC (its “index sponsor” or “S&P Dow Jones”).

SPW is published by S&P Dow Jones, but S&P Dow Jones has no obligation to continue to publish SPW, and may discontinue publication of SPW at any time. SPW is determined, comprised and calculated by S&P Dow Jones without regard to this instrument.

SPW is an equal-weighted version of the S&P 500® Index (“SPX”). SPW has the same eligibility criteria and constituent changes as the SPX and is calculated and maintained in the same manner as the SPX except that, at each rebalancing, each constituent of the SPW is allocated the same weight as every other constituent in the SPW. To calculate an equal-weighted index, the market capitalization for each stock used in the calculation of SPW is redefined so that each index constituent has an equal weight in SPW at each rebalancing date. In addition to being the product of the stock price, the stock’s shares outstanding, and the stock’s investible weight factor (“IWF”), an additional weight factor (“AWF”) is also introduced in the market capitalization calculation to establish equal weighting. The AWF of a stock is the adjustment factor of that stock assigned at each index rebalancing date that makes all index constituents’ modified market capitalization equal as of the reweighting measurement date, while maintaining the total market value of the overall index. Since AWFs are assigned based on prices as of the reweighting measurement date and effected as of a later rebalancing date, the actual weight of each company at the rebalancing differs from the target equal weights due to market movements. Further, since index shares are assigned based on prices one week prior to the rebalancing, the actual weight of each company at the rebalancing differs from the target equal weights due to market movements.

As stock prices move, the weights will shift and exact equality will be lost and, therefore, SPW must be rebalanced from time to time to re-establish the proper weighting.

As discussed more fully in the index supplement under the heading “Underlying Indices and Underlying Index Publishers — S&P 500® Index”, SPX is intended to provide an indication of the pattern of common stock price movement. The calculation of the value of SPX is based on the relative value of the aggregate market value of the common stock of 500 companies as of a particular time compared to the aggregate average market value of the common stocks of 500 similar companies during the base period of the years 1941 through 1943. Select information regarding top constituents and industry and/or sector weightings may be made available by the index sponsor on its website.

The closing level of SPW on December 27, 2024 was 7,161.78 (its “hypothetical initial level”).

Correlation of the Underlying Assets

The graph below illustrates the daily performance of the underlying assets from January 1, 2014 through December 27, 2024. For comparison purposes, each underlying asset has been normalized to have a closing level of 100.00 on January 1, 2014 by dividing the closing level of that underlying asset on each trading day by the closing level of that underlying asset on January 1, 2014 and multiplying by 100.00. We obtained the closing levels used to determine the normalized closing levels set forth below from Bloomberg, without independent verification.

The closer the relationship of the daily returns of the underlying assets over a given period, the more positively correlated those underlying assets are. The lower (or more negative) the correlation of the underlying assets, the less likely it is that those underlying assets will move in the same direction and therefore, the greater the potential for the final level of one of those underlying assets to be less than its downside threshold. This is because the less positively correlated the underlying assets are, the greater the likelihood that at least one of the underlying assets will decrease in value. However, even if the underlying assets have a higher positive correlation, the final level of one or more of the underlying assets might be less than its downside threshold, as the underlying assets may decrease in value together. Although the correlation of the underlying assets’ performance may change over the term of the Securities, the correlations referenced in setting the terms of the Securities are calculated using UBS’ internal models at the time when the terms of the Securities are set and are not derived from the daily returns of the underlying assets over the period set forth below. A lower downside threshold or a higher upside gearing is generally associated with lower correlation of the underlying assets, which reflects a greater potential for a loss on your investment at maturity. See “Key Risks — Risks Relating to Return Characteristics —  Greater expected volatility generally indicates an increased risk of loss at maturity”, “— Risks Relating to Characteristics of the Underlying Assets — You are exposed to the market risk of each underlying asset” and “— Risks Relating to Characteristics of the Underlying Assets — Because the Securities are linked to the least performing underlying asset, you are exposed to a greater risk of losing a significant portion or all of your initial investment at maturity than if the Securities were linked to a single underlying asset or fewer underlying assets“ herein. Past performance of the underlying assets is not indicative of the future performance of the underlying assets.

What Are the Tax Consequences of the Securities?

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

U.S. Tax Treatment. Pursuant to the terms of the Securities, 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 your Securities as prepaid derivative contracts with respect to the underlying assets. If your Securities are so treated, you should generally recognize gain or loss upon the taxable disposition of your Securities in an amount equal to the difference between the amount you receive at such time and the amount you paid for your Securities. Such gain or loss should generally be long-term capital gain or loss if you have held your Securities 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 Securities in the manner described above. However, because there is no authority that specifically addresses the tax treatment of the Securities, it is possible that your Securities 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 Securities 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 Securities for U.S. federal income tax purposes in accordance with the treatment described above and under “Material U.S. Federal Income Tax Consequences”, including the section “— 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 Securities. According to Notice 2008-2, the IRS and the Treasury are actively considering whether the holder of an instrument similar to the Securities 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 Securities 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 Securities, 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. Certain U.S. holders that own “specified foreign financial assets” in excess of an applicable threshold may be subject to reporting obligations with respect to such assets with their tax returns, especially if such assets are held outside the custody of a U.S. financial institution. U.S. holders are urged to consult their tax advisors as to the application of this legislation to their ownership of the Securities.

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 Securities or to generally applicable information reporting and backup withholding requirements with respect to payments on your Securities 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 and Section 871(m) of the Code, discussed below, gain realized from the taxable disposition of a Security generally should not be subject to U.S. tax unless (i) such gain is effectively connected with a trade or business conducted by the non-U.S. holder in the U.S., (ii) the non-U.S. holder is a non-resident alien individual and is present in the U.S. for 183 days or more during the taxable year of such taxable disposition and certain other conditions are satisfied or (iii) the non-U.S. holder has certain other present or former connections with the U.S.

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

Section 871(m). A 30% withholding tax (which may be reduced by an applicable income tax treaty) is imposed under Section 871(m) of the Code on certain “dividend equivalents” paid or deemed paid to a non-U.S. holder with respect to a “specified equity-linked instrument” that references one or more dividend-paying U.S. equity securities or indices containing U.S. equity securities. The withholding tax can apply even if the instrument does not provide for payments that reference dividends. Treasury regulations provide that the withholding tax applies to all dividend equivalents paid or deemed paid on specified equity-linked instruments that have a delta of one (“delta-one specified equity-linked instruments”) issued after 2016 and to all dividend equivalents paid or deemed paid on all other specified equity-linked instruments issued after 2017. However, the IRS has issued guidance that states that the Treasury and the IRS intend to amend the effective dates of the Treasury regulations to provide that withholding on dividend equivalents paid or deemed paid will not apply to specified equity-linked instruments that are not delta-one specified equity-linked instruments and are issued before January 1, 2027.

Based on our determination that the Securities are not “delta-one” with respect to any underlying asset or any underlying constituents, our special U.S. tax counsel is of the opinion that the Securities 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 Securities 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 Securities could be deemed to be reissued for tax purposes upon the occurrence of certain events affecting an underlying asset, the underlying constituents or your Securities, and following such occurrence your Securities 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 Securities under these rules if you enter, or have entered, into certain other transactions in respect of an underlying asset, any underlying constituents or the Securities. If you enter, or have entered, into other transactions in respect of an underlying asset, any underlying constituents or the Securities, you should consult your tax advisor regarding the application of Section 871(m) of the Code to your Securities in the context of your other transactions.

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

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 Securities 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 Securities purchased after the bill was enacted to accrue interest income over the term of the Securities despite the fact that there will be no interest payments over the term of the Securities.

Furthermore, in 2013, the House Ways and Means Committee released in draft form certain proposed legislation relating to financial instruments. If it had been enacted, the effect of this legislation generally would have been to require instruments such as the Securities 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 Securities. You are urged to consult your tax advisor regarding the possible changes in law and their possible impact on the tax treatment of your Securities.

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