HSBC USA Inc. Capped GEARS

$            Securities Linked to a Global Basket due on or about March 31, 2025

Investment Description

These Capped GEARS (the “Securities”) are senior unsecured debt securities issued by HSBC USA Inc. (“HSBC”) linked to the performance of an unequally-weighted basket (the “Basket”) consisting of the following five equity indices (each, a “Reference Asset Component”), with the applicable basket weighting in parenthesis: the EURO STOXX 50^® Index (40.00%), the Nikkei Stock Average (25.00%), the FTSE^® 100 Index (17.50%) and the Swiss Market Index (10.00%), the S&P/ASX 200 Index (7.50%). The Securities will rank equally with all of our other unsecured and unsubordinated debt obligations. If the Basket Return is equal to or greater than zero, we will pay the Principal Amount at maturity plus a return equal to the Upside Gearing multiplied by the Basket Return, up to the Maximum Gain. If the Basket Return is less than zero, HSBC will pay less than the full Principal Amount at maturity, if anything, resulting in a loss of principal that is proportionate to the negative Basket Return. Investing in the Securities involves significant risks. The Securities do not pay any interest. You may lose some or all of your Principal Amount. Any payment on the Securities, including any repayment of principal at maturity, is subject to the creditworthiness of HSBC. If HSBC were to default on its payment obligations, you may not receive any amounts owed to you under the Securities and you could lose your entire investment.

Features

❑     Enhanced Growth Potential Up to the Maximum Gain: At maturity, the Securities enhance any positive Basket Return up to the Maximum Gain. If the Basket Return is negative, investors will be exposed to the downside market risk of the negative Basket Return at maturity.

❑     Full Downside Market Exposure: If the Basket Return is negative, investors will be exposed to the full downside performance of the Basket Return and HSBC will pay less than the full Principal Amount at maturity, resulting in a loss of principal that is proportionate to the negative Underlying Index Return. Accordingly, you could lose some or all of the Principal Amount. Any payment on the Securities, including any repayment of principal, is subject to the creditworthiness of HSBC.

THE SECURITIES ARE SIGNIFICANTLY RISKIER THAN CONVENTIONAL DEBT INSTRUMENTS. THE TERMS OF THE SECURITIES MAY NOT OBLIGATE HSBC TO REPAY THE FULL PRINCIPAL AMOUNT OF THE SECURITIES. THE SECURITIES CAN HAVE DOWNSIDE MARKET RISK SIMILAR TO THE BASKET, WHICH CAN RESULT IN A LOSS OF SOME OR ALL OF THE PRINCIPAL AMOUNT AT MATURITY. THIS MARKET RISK IS IN ADDITION TO THE CREDIT RISK INHERENT IN PURCHASING A DEBT OBLIGATION OF HSBC. YOU SHOULD NOT PURCHASE THE SECURITIES IF YOU DO NOT UNDERSTAND OR ARE NOT COMFORTABLE WITH THE SIGNIFICANT RISKS INVOLVED IN INVESTING IN THE SECURITIES.

YOU SHOULD CAREFULLY CONSIDER THE RISKS DESCRIBED UNDER “KEY RISKS” BEGINNING ON PAGE 6 AND THE MORE DETAILED “RISK FACTORS” BEGINNING ON PAGE S-1 OF THE ACCOMPANYING EQUITY INDEX UNDERLYING SUPPLEMENT AND BEGINNING ON PAGE S-1 OF THE ACCOMPANYING PROSPECTUS SUPPLEMENT BEFORE PURCHASING ANY SECURITIES. EVENTS RELATING TO ANY OF THOSE RISKS, OR OTHER RISKS AND UNCERTAINTIES, COULD ADVERSELY AFFECT THE MARKET VALUE OF, AND THE RETURN ON, YOUR SECURITIES.

Investor Suitability

The Securities may be suitable for you if: ¨   You fully understand the risks inherent in an investment in the Securities, including the risk of loss of your entire initial investment. ¨   You are willing to make an investment where you could lose some or all of your initial investment and are willing to make an investment that may be exposed to similar downside market risk as the Basket and the Reference Asset Components. ¨   You believe that the Basket will appreciate over the term of the Securities, but will not appreciate by more than the Maximum Gain. ¨   You understand and accept that your potential return is limited by the Maximum Gain, and you would be willing to invest in the Securities if the Maximum Gain was set equal to the bottom of the range indicated on the cover hereof (the actual Maximum Gain will be set on the Trade Date). ¨   You understand and accept the risks associated with the Basket and the Reference Asset Components. ¨   You can tolerate fluctuations in the price of the Securities prior to maturity that may be similar to or exceed the downside fluctuations in the level of the Basket or the Reference Asset Components. ¨   You seek an investment with returns based on the performance of companies outside of the United States. ¨   You are willing to hold the Securities to maturity and do not seek an investment for which there is an active secondary market. ¨   You are willing to accept the risk and return profile of the Securities versus a conventional debt security with a comparable maturity issued by HSBC or another issuer with a similar credit rating. ¨   You do not seek current income from your investment and are willing to forgo dividends paid on the stocks included in the Reference Asset Components. ¨   You are willing to assume the credit risk of HSBC, as Issuer of the Securities, and understand that if HSBC defaults on its obligations, you may not receive any amounts due to you, including any repayment of principal.

The Securities may not be suitable for you if: ¨   You do not fully understand the risks inherent in an investment in the Securities, including the risk of loss of your entire initial investment. ¨   You seek an investment that is designed to return your full Principal Amount at maturity. ¨   You are not willing to make an investment in which you could lose all of your Principal Amount or you are not willing to make an investment that may be exposed to similar downside market risk as the Basket or the Reference Asset Components. ¨   You believe that the level of the Basket will decline during the term of the Securities or that any appreciation will be greater than the Maximum Gain. ¨   You seek an investment that participates in the full appreciation in the Basket or that has unlimited return potential. ¨   You are not willing to invest in the Securities if the Maximum Gain is set equal to the bottom of the range indicated on the cover hereof (the actual Maximum Gain will be set on the Trade Date). ¨   You do not understand or accept the risks associated with the Basket or the Reference Asset Components. ¨   You do not seek an investment with returns based on the performance of companies outside of the United States. ¨   You cannot tolerate fluctuations in the price of the Securities prior to maturity that may be similar or exceed the downside fluctuations in the level of the Basket or the Reference Asset Components. ¨   You are unable or unwilling to hold the Securities to maturity and seek an investment for which there will be an active secondary market. ¨   You prefer the lower risk, and therefore accept the potentially lower returns, of conventional debt securities with comparable maturities issued by HSBC or another issuer with a similar credit rating. ¨   You seek current income from your investment or prefer to receive the dividends paid on the stocks included in the Reference Asset Components. ¨   You are not willing or are unable to assume the credit risk of HSBC, as Issuer of the Securities, including any repayment of principal.

The suitability considerations identified above are not exhaustive. Whether or not the Securities are a suitable investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisors have carefully considered the suitability of an investment in the Securities in light of your particular circumstances.

Key Risks

An investment in the Securities involves significant risks. Some of the risks that apply to the Securities are summarized here, but you are urged to read the more detailed explanation of risks relating to the Securities generally in the “Risk Factors” section of the accompanying Equity Index Underlying Supplement and the accompanying prospectus supplement. You are also urged to consult your investment, legal, tax, accounting and other advisors before you invest in the Securities.

Risks Relating to the Structure or Features of the Securities

¨        Risk of Loss at Maturity – The Securities differ from ordinary debt securities in that HSBC will not necessarily pay the full Principal Amount of the Securities at maturity. The return on the Securities at maturity is linked to the performance of the Basket and will depend on whether, and to the extent which, the Basket Return is positive or negative. If the Basket Return is negative, HSBC will pay you less than the Principal Amount at maturity, resulting in a loss of principal equal to the negative Basket Return. Accordingly, you could lose up to 100% of the Principal Amount of the Securities.

¨        Limited Return on the Securities – Your return on the Securities will be limited by the Maximum Gain, regardless of any increase in the level of the Basket, which may be significant. Therefore, you will not benefit from any appreciation of the Basket in excess of an amount that, when multiplied by the Upside Gearing, exceeds the Maximum Gain and your return on the Securities may be less than your return would be on a hypothetical direct investment in the Basket, the Reference Asset Components or in the stocks included in the Reference Asset Components.

¨        The Upside Gearing Applies Only if You Hold the Securities to 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 or the Securities themselves, and the return you realize may be less than the Upside Gearing times the Basket Return, even if that return is positive and, when multiplied by the Upside Gearing, does not exceed the Maximum Gain. You can receive the full benefit of the Upside Gearing, subject to the Maximum Gain, only if you hold your Securities to maturity.

¨        The Amount Payable on the Securities Is Not Linked to the Level of the Basket at Any Time Other Than on the Final Valuation Date – The Basket Return will be based on the Basket Ending Level on the Final Valuation Date, subject to postponement for non-trading days and certain Market Disruption Events. Even if the level of the Basket appreciates prior to the Final Valuation Date but then decreases as of the Final Valuation Date, the Payment at Maturity will be less, and may be significantly less, than it would have been had the Payment at Maturity been linked to the level of the Basket prior to such decrease. Although the actual level of the Basket on the Maturity Date or at other times during the term of the Securities may be higher than the Basket Ending Level, the Payment at Maturity will be based solely on the Basket Ending Level on the Final Valuation Date. You may have to sell the Securities at a loss relative to your initial investment even if the level of the Basket at that time is above the Basket Starting Level.

¨        No Interest Payments – HSBC will not make any interest payments with respect to the Securities.

¨        A change in the level of one or more Reference Asset Components may be offset by a change in the levels of the other Reference Asset Components – A change in the level of one or more Reference Asset Components as of the Final Valuation Date may not correlate with a change in the levels of the other Reference Asset Components. The level of one or more Reference Asset Components may increase, while the levels of the other Reference Asset Components may not increase as much, or may even decrease. Therefore, in calculating the level of the Reference Asset, an increase in the level of one or more Reference Asset Components may be moderated, or wholly offset, by lesser increases or decreases in the levels of the other Reference Asset Components. This effect is further amplified by the differing weights of the Reference Asset Components where changes in lower weighted Reference Asset Components may be offset by even smaller changes in more heavily weighted Reference Asset Components.

Risk Relating to the Reference Asset Components

¨        Changes Affecting the Reference Asset Components – The policies of the sponsors of the Reference Asset Components concerning additions, deletions and substitutions of the stocks included in the Reference Asset Components and the manner in which the sponsors of the Reference Asset Components takes account of certain changes affecting those stocks included in the Reference Asset Components may adversely affect the levels of the Reference Asset Components and the Basket. The policies of the sponsor of the Reference Asset Components with respect to the calculation of the Reference Asset Components could also adversely affect the levels of the Reference Asset Components and the Basket. The sponsors of the Reference Asset Components may discontinue or suspend calculation or dissemination of the Reference Asset Components. Any such actions could have an adverse effect on the value of the Securities.

¨        Non-U.S. Securities Markets Risks – The level of the Reference Asset Components depend upon stocks of non-U.S. companies and are traded on various non-U.S. exchanges. These stocks may be more volatile and may be subject to different political, market, economic, exchange rate, regulatory and other risks than stocks issued by U.S. companies and listed on U.S. exchanges. The foreign securities included in any of the Reference Asset Components may have less liquidity and could be more volatile than many of the securities traded in U.S. or other longer-established securities markets. Direct or indirect government intervention to stabilize the relevant foreign securities markets, as well as cross shareholdings in foreign companies, may affect trading levels or prices and volumes in those markets. The other special risks associated with foreign securities may include, but are not limited to: less liquidity and smaller market capitalizations; less rigorous regulation of securities markets; different accounting and disclosure standards; governmental interference; currency fluctuations; higher inflation; and social, economic and political uncertainties. These factors may adversely affect the performance of the Basket and, as a result, the value of the Securities.

6

¨        The Payments on the Notes Will Not Be Adjusted for Changes in Exchange Rates Relative to the U.S. Dollar Even Though the Stocks Included in the Reference Asset Components are Traded in a Foreign Currency and the Securities are Denominated in U.S. Dollars – Although the equity securities included in the Reference Asset Components are traded in currencies other than U.S. dollars, and the Securities are denominated in U.S. dollars, the amount payable on the Securities at maturity, if any, will not be adjusted for changes in the exchange rates between the U.S. dollar and the currencies in which these non-U.S. equity securities are denominated. Changes in exchange rates, however, may also reflect changes in the applicable non-U.S. economies that in turn may affect the levels of the Reference Asset Components, and therefore the Securities. The amount we pay in respect of the Securities on the maturity date, if any, will be determined solely in accordance with the procedures described in this document.

General Risk Factors

¨        The Securities Are Subject to the Credit Risk of the Issuer – The Securities are senior unsecured debt obligations of the Issuer, and are not, either directly or indirectly, an obligation of any third party. As further described in the accompanying prospectus supplement and prospectus, the Securities will rank on par with all of the other unsecured and unsubordinated debt obligations of HSBC, except such obligations as may be preferred by operation of law. Any payment to be made on the Securities, including any repayment of principal at maturity, depends on the ability of HSBC to satisfy its obligations as they come due. As a result, the actual and perceived creditworthiness of HSBC may affect the market value of the Securities and, in the event HSBC 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 your entire investment.

¨        The Estimated Initial Value of the Securities, Which Is Expected to Be Determined by Us on the Trade Date, Is Expected to Be Less Than the Price to Public and May Differ from the Market Value of the Securities in the Secondary Market, if Any – The Estimated Initial Value of the Securities will be calculated by us on the Trade Date and is expected to be less than the price to public. The Estimated Initial Value will reflect our and our affiliates’ internal funding rate, which is the borrowing rate paid to issue market-linked securities, as well as the mid-market value of the embedded derivatives in the Securities. This internal funding rate is typically lower than the rate we would use when we issue conventional fixed or floating rate debt securities. As a result of the difference between our internal funding rate and the rate we would use when we issue conventional fixed or floating rate debt securities, the Estimated Initial Value of the Securities may be lower if it were based on the prices at which our fixed or floating rate debt securities trade in the secondary market. In addition, if we were to use the rate we use for our conventional fixed or floating rate debt issuances, we would expect the economic terms of the Securities to be more favorable to you. We will determine the value of the embedded derivatives in the Securities by reference to our or our affiliates’ internal pricing models. These pricing models consider certain assumptions and variables, which can include volatility and interest rates. Different pricing models and assumptions could provide valuations for the Securities that are different from our Estimated Initial Value. These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect. The Estimated Initial Value does not represent a minimum price at which we or any of our affiliates would be willing to purchase your Securities in the secondary market (if any exists) at any time.

¨        The Price of Your Securities in the Secondary Market, if Any, Immediately After the Trade Date Is Expected to Be Less Than the Price to Public – The price to public takes into account certain costs. These costs will include our affiliates’ projected hedging profits (which may or may not be realized) for assuming risks inherent in hedging our obligations under the Securities, the underwriting discount and the costs associated with structuring and hedging our obligations under the Securities. These costs, except for the underwriting discount, will be used or retained by us or one of our affiliates. If you were to sell your Securities in the secondary market, if any, the price you would receive for your Securities may be less than the price you paid for them because secondary market prices will not take into account these costs. The price of your Securities in the secondary market, if any, at any time after issuance will vary based on many factors, including the levels of the Basket and changes in market conditions, and cannot be predicted with accuracy. The Securities are not designed to be short-term trading instruments, and you should, therefore, be able and willing to hold the Securities to maturity. Any sale of the Securities prior to maturity could result in a loss to you.

¨        If One of Our Affiliates Were to Repurchase Your Securities Immediately After the Settlement Date, the Price You Receive May Be Higher Than the Estimated Initial Value of the Securities – Assuming that all relevant factors remain constant after the Settlement Date, the price at which HSBC Securities (USA) Inc. may initially buy or sell the Securities in the secondary market, if any, and the value that may initially be used for customer account statements, if any, may exceed the Estimated Initial Value on the Trade Date for a temporary period expected to be approximately 3 months after the Settlement Date. This temporary price difference may exist because, in our discretion, we may elect to effectively reimburse to investors a portion of the estimated cost of hedging our obligations under the Securities and other costs in connection with the Securities that we will no longer expect to incur over the term of the Securities. We will make such discretionary election and determine this temporary reimbursement period on the basis of a number of factors, including the tenor of the Securities and any agreement we may have with the distributors of the Securities. The amount of our estimated costs which we effectively reimburse to investors in this way may not be allocated ratably throughout the reimbursement period, and we may discontinue such reimbursement at any time or revise the duration of the reimbursement period after the Settlement Date of the Securities based on changes in market conditions and other factors that cannot be predicted.

¨        Owning the Securities Is Not the Same as Owning the Stocks Included in the any of the Reference Asset Components – The return on your Securities may not reflect the return you would realize if you actually owned the stocks included in the Reference Asset Components. As a holder of the Securities, you will not have voting rights or rights to receive dividends or other distributions or other rights as would the holders of the stocks included in any of the Reference Asset Components. The Basket Return excludes any cash dividend payments paid on the securities included in or held by any of the Reference Asset Components.

¨        The Securities Are Not Insured or Guaranteed by any Governmental Agency of the United States or any Other Jurisdiction – The Securities are not deposit liabilities or other obligations of a bank and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency or program of the United States or any other jurisdiction. An investment in the Securities is

7

subject to the credit risk of HSBC, and in the event that HSBC is unable to pay its obligations when due, you may not receive any amounts owed to you under the Securities and you could lose your entire investment.

¨        Lack of Liquidity – The Securities will not be listed on any securities exchange or quotation system. One of our affiliates intends to offer to repurchase the Securities in the secondary market but is not required to do so and may cease any such market-making activities at any time without notice. Because other dealers are not likely to make a secondary market for the Securities, the price at which you may be able to trade your Securities is likely to depend on the price, if any, at which one of our affiliates is willing to buy the Securities. This price, if any, will exclude any fees or commissions paid when the Securities were purchased and therefore will generally be lower than such purchase price.

¨        Potential Conflicts of Interest – HSBC, UBS Financial Services Inc., or any of our or their respective affiliates may engage in business with the issuers of the stocks included in the Reference Asset Components, which could affect the price of such stocks or the levels of the Reference Asset Components and thus, may present a conflict between the obligations of HSBC and you, as a holder of the Securities. Additionally, potential conflicts of interest may exist between the Calculation Agent, which may be HSBC or any of its affiliates, and you with respect to certain determinations and judgments that the Calculation Agent must make, which include determining the Payment at Maturity based on the Basket Ending Level as well as whether to postpone the determination of the Basket Ending Level and the Maturity Date if a Market Disruption Event occurs and is continuing on the Final Valuation Date.

¨        Potentially Inconsistent Research, Opinions or Recommendations by HSBC, UBS or Their Respective Affiliates – HSBC, UBS Financial Services Inc., or their respective affiliates may publish research, express opinions or provide recommendations that are inconsistent with investing in or holding the Securities and which may be revised at any time. Any such research, opinions or recommendations could affect the level of the Basket and the Reference Asset Components or the price of the stocks included in the Reference Asset Components, and therefore, the market value of the Securities.

¨        Economic and Market Factors Affecting the Terms and Market Price Prior to Maturity – Because structured notes, including the Securities, can be thought of as having a debt and 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 level of the Basket; the volatility of the Basket and the Reference Asset Components; the dividend rate paid on stocks included in the Reference Asset Components; the time remaining to the maturity of the Securities; interest rates in the markets in general; geopolitical conditions and economic, financial, political, regulatory, judicial or other events; and the creditworthiness of HSBC. These and other factors are unpredictable and interrelated and may offset or magnify each other.

¨        Potential HSBC and UBS Impact on Price – Trading or transactions by HSBC, UBS Financial Services Inc. or any of our or their respective affiliates in the stocks included in the Reference Asset Components or in futures, options, exchange-traded funds or other derivative products on stocks included in the Reference Asset Components, may adversely affect the market value of the stocks included in the Reference Asset Components, the levels of the Reference Asset Components, and, therefore, the market value of your Securities.

¨        Uncertain Tax Treatment – Significant aspects of the tax treatment of the Securities are uncertain. You should consult your tax advisor about your own tax situation. See the discussion under “What Are the Tax Consequences of the Securities?” herein and the discussion under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.

Scenario Analysis and Examples at Maturity

The scenario analysis and examples below are provided for illustrative purposes only and are hypothetical. They do not purport to be representative of every possible scenario concerning increases or decreases in the level of the Basket relative to the Basket Starting Level. The hypothetical terms used below are not the actual terms that will apply to the Securities. The actual terms will be set on the Trade Date and will be indicated on the cover of the applicable pricing supplement. We cannot predict the Basket Ending Level. You should not take the scenario analysis and these examples as an indication or assurance of the expected performance of the Basket. The numbers appearing in the examples below have been rounded for ease of analysis. The following scenario analysis and examples illustrate the Payment at Maturity for a $10.00 Security on a hypothetical offering of the Securities, based on the following assumptions:

Investment term:	14 months
Basket Starting Level:	100.00
Upside Gearing:	3.00
Maximum Gain:	22.00%

Example 1— The level of the Basket increases from a Basket Starting Level of 100.00 to a Basket Ending Level of 102.50.

The Basket Return is greater than zero and expressed as a formula:

Basket Return = (102.50 – 100.00) / 100.00 = 2.50%

Because the Basket Return is greater than zero, the Payment at Maturity for each $10.00 Principal Amount of Securities is equal to the lesser of:

(A) $10 + [$10 × (2.50% × 3.00)], and

(B) $10 + ($10 × 22.00%)

Payment at Maturity = $10.75

Example 2— The level of the Basket increases from a Basket Starting Level of 100.00 to a Basket Ending Level of 130.00.

The Basket Return is greater than zero and expressed as a formula:

Basket Return = (130.00 – 100.00) / 100.00 = 30.00%

Because the Basket Return is greater than zero and, when multiplied by the Upside Gearing, is greater than the Maximum Gain, the Payment at Maturity for each $10.00 Principal Amount of Securities will be calculated as follows:

Payment at Maturity = $10 + ($10 × 22.00%) = $12.20

Example 3— The level of the Basket decreases from a Basket Starting Level of 100.00 to a Basket Ending Level of 25.00.

The Basket Return is negative and expressed as a formula:

Basket Return = (25.00 – 100.00) / 100.00 = -75.00%

Payment at Maturity = $10 + ($10 × -75.00%) = $2.50

Because the Basket Return is less than zero, the Securities will be fully exposed to any decline in the level of the Basket on the Final Valuation Date. In this case, you would incur a loss of 75.00% of the Principal Amount.

If the Basket Return is negative, you will lose some or all of your Principal Amount at maturity.

What Are the Tax Consequences of the Securities?

You should carefully consider, among other things, the matters set forth in the section “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement. The following discussion summarizes the U.S. federal income tax consequences of the purchase, beneficial ownership, and disposition of each of the Securities. This summary supplements the section “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement and supersedes it to the extent inconsistent therewith.

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 those of the Securities. Under one reasonable approach, the Securities should be treated as pre-paid executory contracts with respect to the Basket. HSBC intends to treat the Securities consistent with this approach and pursuant to the terms of the Securities, you agree to treat the Securities under this approach for all U.S. federal income tax purposes. Subject to certain limitations described in the accompanying prospectus supplement, and based on certain factual representations received from HSBC, in the opinion of HSBC’s special U.S. tax counsel, Mayer Brown LLP, it is reasonable to treat the Securities in accordance with this approach. Pursuant to this approach, HSBC does not intend to report any income or gain with respect to the Securities prior to their maturity or an earlier sale or exchange and HSBC intends to treat any gain or loss upon maturity or an earlier sale or exchange as long-term capital gain or loss, provided that you have held the Security for more than one year at such time for U.S. federal income tax purposes. See "U.S. Federal Income Tax Considerations — Tax Treatment of U.S. Holders — Certain Notes Treated as a Put Option and a Deposit or an Executory Contract — Certain Notes Treated as Executory Contracts" in the accompanying prospectus supplement for the U.S. federal income tax considerations applicable to Securities that are treated as pre-paid executory contracts.

Because 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 those of the Securities, other characterizations and treatments are possible and the timing and character of income in respect of the Securities might differ materially and adversely from the treatment described above. For example, the Securities could be treated as debt instruments that are “contingent payment debt instruments” for U.S. federal income tax purposes, subject to the treatment described under the heading “U.S. Federal Income Tax Considerations — Tax Treatment of U.S. Holders — U.S. Federal Income Tax Treatment of the Notes as Indebtedness for U.S. Federal Income Tax Purposes — Contingent Notes” in the prospectus supplement.

In Notice 2008-2, the Internal Revenue Service (“IRS”) and the Treasury Department requested comments as to whether the purchaser of an exchange traded note or pre-paid forward contract (which may include the Securities) should be required to accrue income during its term under a mark-to-market, accrual or other methodology, whether income and gain on such a note or contract should be ordinary or capital, and whether foreign holders should be subject to withholding tax on any deemed income accrual. Accordingly, it is possible that regulations or other guidance could provide that a U.S. holder (as defined in the accompanying prospectus supplement) of the Securities is required to accrue income in respect of the Securities prior to the receipt of payments with respect to the Securities or their earlier sale. Moreover, it is possible that any such regulations or other guidance could treat all income and gain of a U.S. holder in respect of the Securities as ordinary income (including gain on a sale). Finally, it is possible that a non-U.S. holder (as defined in the accompanying prospectus supplement) of the Securities could be subject to U.S. withholding tax in respect of the Securities. It is unclear whether any regulations or other guidance would apply to the Securities (possibly on a retroactive basis). Prospective investors are urged to consult with their tax advisors regarding Notice 2008-2 and the possible effect to them of the issuance of regulations or other guidance that affects the U.S. federal income tax treatment of the Securities.

We will not attempt to ascertain whether any of the entities whose stock is included in the Reference Asset Components would be treated as a passive foreign investment company (“PFIC”) or United States real property holding corporation (“USRPHC”), both as defined for U.S. federal income tax purposes. If one or more of the entities whose stock is included in the Reference Asset Components were so treated, certain adverse U.S. federal income tax consequences might apply. You should refer to information filed with the SEC and other authorities by the entities whose stock is included in the Reference Asset Components and consult your tax advisor regarding the possible consequences to you if one or more of the entities whose stock is included in a Reference Asset Component is or becomes a PFIC or USRPHC.

Under current law, while the matter is not entirely clear, individual non-U.S. holders, and entities whose property is potentially includible in those individuals’ gross estates for U.S. federal estate tax purposes (for example, a trust funded by such an individual and with respect to which the individual has retained certain interests or powers), should note that, absent an applicable treaty benefit, the Securities are likely to be treated as U.S. situs property, subject to U.S. federal estate tax. These individuals and entities should consult their tax advisors regarding the U.S. federal estate tax consequences of investing in the Securities.

A “dividend equivalent” payment is treated as a dividend from sources within the United States and such payments generally would be subject to a 30% U.S. withholding tax if paid to a non-U.S. holder. Under U.S. Treasury Department regulations, payments (including deemed payments) with respect to equity-linked instruments (“ELIs”) that are “specified ELIs” may be treated as dividend equivalents if such specified ELIs reference an interest in an “underlying security,” which is generally any interest in an entity taxable as a corporation for U.S. federal income tax purposes if a payment with respect to such interest could give rise to a U.S. source dividend. However, IRS guidance provides that withholding on dividend equivalent payments will not apply to specified ELIs that are not delta-one instruments and that are issued before January 1, 2025. Based on the Issuer’s determination that the Securities are not “delta-one” instruments, non-U.S. holders should not be subject to withholding on dividend equivalent payments, if any, under the Securities. However, it is possible that the Securities could be treated as deemed reissued for U.S. federal income tax purposes upon the occurrence of certain events affecting the Reference Asset Components or the Securities, and following such occurrence the Securities could be treated as subject to withholding on dividend equivalent payments. Non-U.S. holders that enter, or have entered, into other transactions in respect of the Reference Asset Components or the Securities should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the Securities and their other transactions. If any payments are treated as dividend equivalents subject to withholding, we (or the applicable paying agent) would be entitled to withhold taxes without being required to pay any additional amounts with respect to amounts so withheld.

Events of Default and Acceleration

If the Securities have become immediately due and payable following an Event of Default (as defined in the accompanying prospectus) with respect to the Securities, the Calculation Agent will determine the accelerated payment due and payable at maturity in the same general manner as described herein. In that case, the scheduled trading day immediately preceding the date of acceleration will be used as the Final Valuation Date for the purposes of determining the Basket Return. If a Market Disruption Event exists with respect to a Reference Asset Component on that scheduled trading day, then the accelerated Final Valuation Date for that Reference Asset Component will be postponed for up to five scheduled trading days (in the same manner used for postponing the originally scheduled Final Valuation Date). The accelerated Maturity Date will also be postponed by an equal number of business days as the latest postponed Final Valuation Date. For the avoidance of doubt, if no Market Disruption Event exists with respect to a Reference Asset Component on the scheduled trading day preceding the date of acceleration, the determination of such Reference Asset Component’s Final Level will be made on such date, irrespective of the existence of a Market Disruption Event with respect to any other Reference Asset Component occurring on such date.

If the Securities have become immediately due and payable following an Event of Default, you will not be entitled to any additional payments with respect to the Securities. For more information, see “Description of Debt Securities — Senior Debt Securities — Events of Default” in the accompanying prospectus.

Supplemental Plan of Distribution (Conflicts of Interest)

Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc., an affiliate of HSBC, will purchase the Securities from HSBC for distribution to UBS Financial Services Inc.

HSBC has agreed to indemnify the Agent against liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments that the Agent may be required to make relating to these liabilities as described in the prospectus supplement and the prospectus. The Agent may allow a concession to its affiliates not in excess of the underwriting discount set forth on the cover hereof.

Subject to regulatory constraints, HSBC USA Inc. (or an affiliate thereof) intends to offer to purchase the Securities in the secondary market, but is not required to do so and may cease making such offers at any time. HSBC or its affiliate will enter into swap agreements or related hedge transactions with one of its other affiliates or unaffiliated counterparties, which may include the Agent, in connection with the sale of the Securities and the Agent and/or an affiliate may earn additional income as a result of payments pursuant to the swap or related hedge transactions.
