PRICING SUPPLEMENT Dated March 1, 2021 Filed Pursuant to Rule 424(b)(2) Registration Statement No. 333-253432 (To Prospectus dated February 24, 2021, Index Supplement dated February 24, 2021 and Product Supplement dated February 24, 2021)

UBS AG $2,973,000 Trigger Autocallable Notes

Linked to the S&P 500 ® Index due March 6, 2024

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 S&P 500 ® 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 (annually), including the final valuation date, is equal to or greater than the call threshold level, which is equal to the initial level. If the Notes are subject to an automatic call, UBS will pay 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 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 trade date to the final valuation date (the “underlying return”) and, in extreme situations, you could lose all of your initial investment. Investing in the Notes involves significant risks. You may lose a significant portion or all of your initial investment. 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. Any payment on the Notes, including any repayment of principal, is subject to the creditworthiness of UBS. If UBS were to default on its payment obligations you may not receive any amounts owed to you under the Notes and you could lose all of your initial investment.

Features

q

Automatic Call Feature — UBS will automatically call the Notes if the closing level of the underlying asset on any observation date (annually), including the final valuation date, is equal to or greater than the call threshold level, which is equal to the initial level. If the Notes are subject to an automatic call, UBS will pay 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 under the Notes.

q

Contingent Repayment of Principal at Maturity with Potential for Full Downside Market Exposure — If by maturity the Notes have not been subject to an automatic call and the final level is equal to or greater than the downside threshold, UBS will pay you a cash payment per Note equal to the principal amount. If, however, 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 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 to maturity. Any payment on the Notes, including any repayment of principal, is subject to the creditworthiness of UBS.

We expect to deliver the Notes against payment on the third business day following the trade date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two business days (T+2), 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 two business days 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.

**

Subject to postponement in the event of a market disruption event, as described in the accompanying product supplement.

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.

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 or the underlying constituents. 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 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 contingent repayment of principal applies only at 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 that time is equal to or greater than the downside threshold and call threshold level. All payments on the Notes are subject to the creditworthiness of UBS.

¨ No interest payments — UBS will not pay any interest with respect to the Notes.

¨ Your potential return on the Notes is limited to any call return and you will not participate in any appreciation of the underlying asset or any underlying constituent — The return potential of the Notes is limited to the pre-specified call return resulting from an automatic call regardless of any appreciation of the underlying asset. Investors will not participate in any appreciation in the closing level of the underlying asset from the initial level. The Notes will only be subject to an automatic call if the closing level or the final level, as applicable, of the underlying asset is equal to or greater than the call threshold level. In addition, 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 a Note is subject to an automatic call, the lower your return 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. Furthermore, if the Notes are not subject to an automatic call, you will be subject to the decline in the level of the underlying asset if the final level is less than the downside threshold, even though you cannot participate in any appreciation in the level of the underlying asset or the underlying constituents. As a result, the return on an investment in the Notes could be less than the return on a hypothetical direct investment in the underlying asset or in any or all of the underlying constituents. In addition, as an owner of the Notes, you will not have voting rights or any other rights of a holder of the 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 the 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 on the final valuation date 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 return. 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 set forth herein. 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 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 value of the underlying constituents. The level of the underlying asset can rise or fall sharply due to factors specific to the underlying asset and its underlying constituents and their issuers (each, an “underlying constituent issuer”), such as stock price volatility, earnings and financial conditions, corporate, industry and regulatory developments, management changes and decisions and other events, as well as general market factors, such as general stock market or commodity market volatility and levels, interest rates and economic and political conditions. Recently, the coronavirus infection has caused volatility in the global financial markets and a slowdown in the global economy. Coronavirus or any other communicable disease or infection may adversely affect the underlying constituent issuers and, therefore, the underlying asset. You, as an investor in the Notes, should conduct your own investigation into the underlying asset and the 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 and there can be no assurance that the closing level or the 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. 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 risks associated with the relevant markets tracked by 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.

Field: Page; Sequence: 7

Field: /Page

¨ The underlying asset reflects price return, not total return — The return on your Notes is based on the performance of the underlying asset, which reflects the changes in the market prices of the underlying constituents. They are not, however, linked to a “total return” index or strategy, which, in addition to reflecting those price returns, would also reflect dividends paid on the underlying constituents. The return on your Notes will not include such a total return feature or dividend component.

¨ Changes affecting the underlying asset, including regulatory changes, could have an adverse effect on the market value of, and any amount payable on, the 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. Any such actions could have an adverse effect on the market value of, and any amount payable on, the Notes. 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 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 events such as these occur and no successor index is selected, the calculation agent may determine the closing level or final level, as applicable, of the underlying asset — and thus any amount payable on the Notes — in a manner it considers appropriate as described further in the accompanying product supplement under “General Terms of the Securities — Discontinuance of, Adjustments to or Benchmark Event Affecting an Underlying Index; Alteration of Method of Calculation”.

¨ 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 any amount payable on, your Notes.

Estimated Value Considerations

¨ The estimated initial value is a theoretical price; the actual price that 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 under “— 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.

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. 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. If you are able to sell your Notes prior to maturity, you may have to sell them at a substantial loss. Furthermore, there can be no assurance that a secondary market for the Notes will develop. 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.

¨ 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 dividends paid 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; whether the underlying asset is currently or has been less than the call threshold level; the availability of comparable instruments; 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 conflict 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 as well as the inclusion in the issue price of the underwriting discount, 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 the underlying asset — 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, may adversely affect the level of the underlying asset on any observation date, including the final valuation date and, therefore, the market value of the Notes and any payout pursuant to an automatic call or at maturity.

¨ Potential conflict of interest — UBS and its affiliates may engage in business with any underlying constituent issuer or trading activities related to one or more underlying constituents, 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 levels of the underlying asset. The calculation agent can postpone the determination of the terms of the Notes 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 discount, 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.

¨ 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 market value of, and any amounts payable 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 to which the Notes are linked.

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 Financial Market Supervisory Authority (“FINMA”) has broad statutory powers to take measures and actions in relation to UBS if (i) it concludes that there is justified concern that UBS is over-indebted or has serious liquidity problems or (ii) UBS fails to fulfill the applicable capital adequacy requirements (whether on a standalone or consolidated basis) after expiry of a deadline set by FINMA. 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. The resolution regime of the Swiss Banking Act is further detailed in Ordinance of 30 August 2012 of FINMA on the Insolvency of Banks and Securities Dealers, as amended (the “Swiss Banking Insolvency Ordinance”). In restructuring proceedings, FINMA, as resolution authority, is competent to approve the resolution plan. The resolution 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 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. The Swiss Banking Insolvency Ordinance provides that a debt-to-equity swap and/or a write-off of debt and other obligations (including the Notes) may take place only after (i) all debt instruments issued by UBS qualifying as additional tier 1 capital or tier 2 capital have been converted into equity or written-off, as applicable, and (ii) the existing equity of UBS has been fully cancelled. While the Swiss Banking Insolvency Ordinance does not expressly address the order in which a write-off of debt instruments other than debt instruments qualifying as additional tier 1 capital or tier 2 capital should occur, it states that debt-to-equity swaps should occur in the following order: first, all subordinated claims not qualifying as regulatory capital; second, all other claims not excluded by law from a debt-to-equity swap (other than deposits); and third, deposits (in excess of the amount privileged by law). However, given the broad discretion granted to FINMA as the resolution authority, any restructuring plan in respect of UBS could provide that the claims under or in connection with the Notes will be partially or fully converted into equity or written-off, while preserving other obligations of UBS that rank pari passu with, or even junior to, UBS’ obligations under the Notes. Consequently, the exercise of any such powers by FINMA 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. In the case of restructuring proceedings with respect to a systemically important Swiss bank (such as UBS), the creditors whose claims are affected by the restructuring plan will not have a right to vote on, reject, or seek the suspension of the restructuring plan. In addition, if a restructuring plan has been approved by FINMA, the rights of a creditor to seek judicial review of the restructuring plan (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. In particular, a court may not suspend the implementation of the restructuring plan. Furthermore, even if a creditor successfully challenges the restructuring plan, the court can only require the relevant creditor to be compensated ex post and there is currently no guidance as to on what basis such compensation would be calculated or how it would be funded.

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.

Hypothetical Examples of How the Notes Might Perform

The below examples are based on hypothetical terms. The actual terms are indicated on the cover hereof.

The examples below illustrate the payment upon a 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):

Principal Amount:	$1,000.00
Term:	Approximately 3 years
Call return rate:	10.00% per annum
Observation Dates:	Annually
Initial Level:	3,500
Call Threshold:	3,500 (which is 100.00% of the Initial Level)
Downside Threshold:	2,100 (which is 60.00% 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.

| Date | Closing Level | Payment (per
Note) |
| --- | --- | --- |
| First Observation Date | 3,750 ( equal to or greater than Call Threshold Level) | $1,100.00 (Call Price) |
| | Total Payment: | $1,100.00 (10.00% total return) |

Because the Notes are subject to an automatic call on the first potential call settlement date (which is approximately 1 year after the trade date), UBS will pay on the corresponding call settlement date a total of $1,100.00 per Note (reflecting your principal amount plus the applicable call return), a 10.00% total return 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.

| Date | Closing Level | Payment (per
Note) |
| --- | --- | --- |
| First Observation Date | 3,300 ( less than Call Threshold Level) | $0 |
| Second Observation Date | 3,600 ( equal to or greater than Call Threshold Level) | $1,200.00 (Call Price) |
| | Total Payment: | $1,200.00 (20.00% total return) |

Because the Notes are subject to an automatic call on the second potential call settlement date (which is approximately two years after the trade date), UBS will pay on the corresponding call settlement date a total of $1,200.00 per Note (reflecting your principal amount plus the applicable call return), a 20.00% total return on the Notes. You will not receive any further payments on the Notes.

Example 3 — The Final Level is equal to or greater than the Call Threshold Level on the Final Valuation Date.

| Date | Closing Level | Payment (per
Note) |
| --- | --- | --- |
| First Observation Date | 2,700 ( less than Call Threshold Level) | $0 |
| Second Observation Date | 3,100 ( less than Call Threshold Level) | $0 |
| Final Valuation Date | 3,700 ( equal to or greater than Call Threshold Level and Downside Threshold) | $1,300.00 (Call Price) |
| | Total Payment: | $1,300.00 (30.00% total return) |

Because the Notes are subject to an automatic call on the final valuation date (which is approximately three years after the trade date), UBS will pay on the corresponding call settlement date (which is also the maturity date) a total of $1,300.00 per Note (reflecting your principal amount plus the applicable call return), a 30.00% total return 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.

| Date | Closing Level | Payment (per
Note) |
| --- | --- | --- |
| First Observation Date | 2,800 ( less than Call Threshold Level) | $0 |
| Second Observation Date | 3,000 ( less than Call Threshold Level) | $0 |
| Final Valuation Date | 3,100 ( less than Call Threshold Level; equal to or greater than Downside Threshold) | $1,000.00 (Payment at Maturity) |
| | Total Payment: | $1,000.00 (0.00% total return) |

Because the Notes are not subject to an automatic call on any observation date (including the final valuation date) and the final level is equal to or greater than the downside threshold, on the maturity date UBS will pay $1,000.00 per Note (reflecting your principal amount), a 0.00% total 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.

| Date | Closing Level | Payment (per
Note) |
| --- | --- | --- |
| First Observation Date | 2,900 ( less than Call Threshold Level) | $0 |
| Second Observation Date | 2,200 ( less than Call Threshold Level) | $0 |
| Final Valuation Date | 1,400 ( less than Call Threshold Level and Downside Threshold) | $1,000.00 x (1 + Underlying Return) = $1,000.00 x [1 + (-60%)] = $1,000.00 x 0.40 = $400.00 (Payment at Maturity) |
| | Total Payment: | $400.00 (60.00% loss) |

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

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. If the Notes are not subject to an automatic call, you may lose a significant portion or all of your initial investment. 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 payments in respect of an automatic call or any repayment of principal, is subject to the creditworthiness of UBS. If UBS were to default on its payment obligations, you may not receive any amounts owed to you under the Notes and you could lose all of your initial investment.

Information About the Underlying Asset

S&P 500 ® Index

We have derived all information regarding the S&P 500 ® Index (“SPX”) 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”).

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

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.

Eleven main groups of companies comprise SPX, with the percentage weight of each group in the index as a whole as of January 29, 2021 as follows: Information Technology (27.8%), Health Care (13.8%), Consumer Discretionary (12.9%), Communication Services (10.7%), Financials (10.3%), Industrials (8.1%), Consumer Staples (6.2%), Utilities (2.8%), Materials (2.6%), Real Estate (2.5%) and Energy (2.4%). The weightings for each sector are rounded to the nearest tenth of a percent and, therefore, may not equal 100%. Effective February 20, 2019, company additions to the SPX should have an unadjusted company market capitalization of $8.2 billion or more (an increase from the previous requirement of an unadjusted company market capitalization of $6.1 billion or more) and a security level float-adjusted market capitalization that is at least $4.1 billion.

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. UBS has not conducted any independent review or due diligence of any publicly available information with respect to the underlying asset.

Historical Information

The graph below illustrates the performance of the underlying asset from January 1, 2011 through March 1, 2021, based on the daily closing levels as reported by Bloomberg, without independent verification. UBS has not conducted any independent review or due diligence of publicly available information obtained from Bloomberg. The closing level of the underlying asset on March 1, 2021 was 3,901.82. The dotted lines represent the call threshold level of 3,901.82 and the downside threshold of 2,341.09, which are equal to 100.00% and 60.00%, respectively, of the initial level. Past 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 unless and until such time as the IRS and the Treasury determine that some other treatment is more appropriate.

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”, including the section “— Securities Treated as Prepaid Derivatives or Prepaid Forwards” in the accompanying product supplement, unless and until such time as the Treasury and the IRS 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 current income 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 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.

Field: Page; Sequence: 13

Field: /Page

Section 897. We will not attempt to ascertain whether any underlying constituent issuer would be treated as a “United States real property holding corporation” (“USRPHC”) within the meaning of Section 897 of the Code. We also have not attempted to determine whether the Notes should be treated as “United States real property interests” (“USRPI”) as defined in Section 897 of the Code. If any such entity and the Notes 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 Note upon a taxable disposition of a Note to U.S. federal income tax on a net basis, and the proceeds from such a taxable disposition could be subject to a 15% withholding tax. Non-U.S. holders should consult their tax advisors regarding the potential treatment of any underlying constituent issuer for their Notes as a USRPHC and the Notes 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 2018. 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, 2023.

Based on our determination that the Notes are not “delta-one” with respect to the underlying asset or any U.S. 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, the underlying constituents or the Notes. A non-U.S. holder that enters, or has entered, into other transactions in respect of the underlying asset, the 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 have agreed to sell to UBS Securities LLC, and UBS Securities LLC has agreed 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 has agreed to 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. 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 have agreed to purchase Notes from a third-party dealer at a purchase price of at least $997.50 per Note, and such third-party dealer, with respect to such sales, may have agreed to forgo some or all of the underwriting discount. 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 discount) 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.

Prohibition of Sales to EEA & 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 European Economic Area (“EEA”) or the United Kingdom (the “UK”). 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”); (ii) a customer within the meaning of Directive (EU) 2016/97, as amended, 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, as amended (the “PRIIPs Regulation”), for offering or selling the Notes or otherwise making them available to retail investors in the EEA or the UK has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the EEA or the UK may be unlawful under the PRIIPs Regulation.
