HSBC USA Inc. Capped GEARS

$            Securities Linked to the Russell 2000^® Index due on or about September 30, 2022

Investment Description
These Capped GEARS (the “Securities”) are senior unsecured debt securities issued by HSBC USA Inc. (“HSBC”) linked to the performance of the Russell 2000® Index (the “Underlying Index”). The Securities will rank equally with all of our other unsecured and unsubordinated debt obligations. If the Underlying Index Return is equal to or greater than zero, we will pay the Principal Amount at maturity plus a return equal to 3.00 (the “Upside Gearing”) multiplied by the Underlying Index Return, up to the Maximum Gain. If the Underlying Index 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 Underlying Index 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.

qEnhanced Growth Potential Up to the Maximum Gain: At maturity, the Securities enhance any positive Underlying Index Return up to the Maximum Gain. If the Underlying Index Return is negative, investors will be exposed to the downside market risk of the negative Underlying Index Return at maturity. qFull Downside Market Exposure: If the Underlying Index Return is negative, investors will be exposed to the full downside performance of the Underlying Index 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.	Trade Date                                                                  July 27, 2021 Settlement Date July                                                  30, 2021 Final Valuation Date (2)                                      September 27, 2022 Maturity Date (2)                                                 September 30, 2022 (1) Expected. In the event we make any change to the expected Trade Date and Settlement Date, the Final Valuation Date and Maturity Date will be changed so that the stated term of the Securities remains the same. (2) See page 4 for additional details.
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 UNDERLYING INDEX, 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 Underlying Index. ¨You believe that the Underlying Index 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 Underlying Index. ¨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 Underlying Index. ¨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 Underlying Index. ¨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 some or all of your Principal Amount and you are not willing to make an investment that may be exposed to similar downside market risk as the Underlying Index. ¨You believe that the level of the Underlying Index will decline during the term of the Securities, and that any appreciation will be greater than the Maximum Gain. ¨You seek an investment that participates in the full appreciation in the Underlying Index 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 Underlying Index. ¨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 Underlying Index. ¨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 Underlying Index. ¨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.

Investment Timeline

 

Trade Date	The Initial Level is observed and the terms of the Securities are set.
Maturity Date	The Final Level and Underlying Index Return are determined on the Final Valuation Date. If the Underlying Index Return is greater than zero, HSBC will pay you a cash payment per Security equal to the lesser of: (A) $10 + [$10 × (the Underlying Index Return × Upside Gearing)]; and (B) $10 + ($10 × the Maximum Gain) If the Underlying Index Return is negative on the Final Valuation Date, HSBC will pay you a cash payment at maturity that will be less than the Principal Amount of $10 per Security, resulting in a loss of principal that is proportionate to the negative Underlying Index Return, equal to: $10 + ($10 × Underlying Index Return). In this case, you could lose up to 100% of the Principal Amount of the Securities.

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 Underlying Index and will depend on whether, and to the extent which, the Underlying Index Return is positive or negative. If the Underlying Index Return is negative, HSBC will pay you less than the Principal Amount at maturity, resulting in a loss of principal equal to the negative Underlying Index 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 Underlying Index, which may be significant. Therefore, you will not benefit from any appreciation of the Underlying Index 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 Underlying Index or in the stocks included in the Underlying Index.

¨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 Underlying Index 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 Underlying Index at Any Time Other Than on the Final Valuation Date – The Underlying Index Return will be based on the Final Level on the Final Valuation Date, subject to postponement for non-trading days and certain market disruption events. Even if the level of the Underlying Index 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 Underlying Index prior to such decrease. Although the actual level of the Underlying Index on the Maturity Date or at other times during the term of the Securities may be higher than the Final Level, the Payment at Maturity will be based solely on the Final 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 Underlying Index at that time is above the Initial Level.

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

Risk Relating to the Underlying Index

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

¨        Small-Capitalization Risk — The RTY tracks companies that may be considered small-capitalization companies. These companies often have greater stock price volatility, lower trading volume and less liquidity than large-capitalization companies and therefore the respective index level may be more volatile than an investment in stocks issued by larger companies. Stock prices of small-capitalization companies may also be more vulnerable than those of larger companies to adverse business and economic developments, and the stocks of small-capitalization companies may be thinly traded, making it difficult for the RTY to track them. In addition, small-capitalization companies are often less stable financially than large-capitalization companies and may depend on a small number of key personnel, making them more vulnerable to loss of personnel. Small-capitalization companies are often subject to less analyst coverage and may be in early, and less predictable, periods of their corporate existences. These companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and competitive strengths than large-capitalization companies, and are more susceptible to adverse developments related to their products.

General Risk Factors

¨The Securities Are Subject to the Credit Risk of the Issuer – The Securities are senior unsecured debt obligations of the Issuer, HSBC, 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 Will 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

6

Initial Value will reflect our internal funding rate, which is the borrowing rate we pay 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 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 level of the Underlying Index 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 7 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 Underlying Index – The return on your Securities may not reflect the return you would realize if you actually owned the stocks included in the Underlying Index. 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 the Underlying Index. The Underlying Index is a price return index, and the Underlying Index Return excludes any cash dividend payments paid on its component stocks.

¨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 subject to the credit risk of HSBC, and in the event 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 comprising the Underlying Index, which could affect the price of such stocks or the level of the Underlying Index 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 Final Level as well as whether to postpone the determination of the Final 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 Underlying Index or the price of the stocks included in the Underlying Index, and therefore, the market value of the Securities.

7

¨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 Underlying Index; the volatility of the Underlying Index; the dividend rate paid on stocks included in the Underlying Index; 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 comprising the Underlying Index or in futures, options, exchange-traded funds or other derivative products on stocks comprising the Underlying Index, may adversely affect the market value of the stocks comprising the Underlying Index, the level of the Underlying Index, 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 Underlying Index relative to the Initial Level. The hypothetical terms used below are not the actual terms that will apply to the Notes. 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 Final Level. You should not take the scenario analysis and these examples as an indication or assurance of the expected performance of the Underlying Index. 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 Security on a hypothetical offering of the Securities based on the following assumptions:

Investment term:	Approximately 1 year and 2 months
Initial Level:	1,000.00
Upside Gearing:	3.00
Maximum Gain:	14.00%

Example 1— The level of the Underlying Index increases from an Initial Level of 1,000.00 to a Final Level of 1,025.00.

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

Underlying Index Return = (1,025.00 – 1,000.00) / 1,000.00 = 2.50%

Because the Underlying Index Return is greater than zero, the Payment at Maturity for each $10 Principal Amount of Securities is equal to the lesser of:

(A) $10 + [$10 × (2.50% × 3.00)], and

(B) $10 + ($10 × 14.00%)

Payment at Maturity = $10.75

Example 2— The level of the Underlying Index increases from an Initial Level of 1,000.00 to a Final Level of 1,300.00.

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

Underlying Index Return = (1,300.00 – 1,000.00) / 1,000.00 = 30.00%

Because the Underlying Index Return is greater than zero, the Payment at Maturity for each $10 Principal Amount of Securities is equal to the lesser of:

(A) $10 + [$10 × (30.00% × 3.00)], and

(B) $10 + ($10 × 14.00%)

Payment at Maturity = $11.40

Example 3— The level of the Underlying Index decreases from an Initial Level of 1,000.00 to a Final Level of 800.00.

The Underlying Index Return is negative and expressed as a formula:

Underlying Index Return = (800.00 – 1,000.00) / 1,000.00 = -20.00%

Payment at Maturity = $10 + ($10 × -20.00%) = $8.00

Because the Underlying Index Return is less than zero, the Securities will be fully exposed to any decline in the level of the Underlying Index on the Final Valuation Date. In this case, you would incur a loss of 20.00% of the Principal Amount.

If the Underlying Index 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 Underlying Index. 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 Underlying Index 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 Underlying Index 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 Underlying Index and consult your tax advisor regarding the possible consequences to you if one or more of the entities whose stock is included in the Underlying Index 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, 2023. 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 Underlying Index 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 Underlying Index 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.

PROSPECTIVE PURCHASERS OF SECURITIES SHOULD CONSULT THEIR TAX ADVISORS AS TO THE FEDERAL, STATE, LOCAL, AND OTHER TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF SECURITIES.

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 Underlying Index Return. If a Market Disruption Event exists with respect to the Underlying Index on that scheduled trading day, then the accelerated Final Valuation Date for the Underlying Index 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.

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. (the “Agent”). HSBC Securities (USA) Inc. will agree to sell to the Agent, and the Agent will agree to purchase, all of the Securities at the price to public less the underwriting discount indicated on the cover hereof. 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.

In addition, HSBC Securities (USA) Inc. or another of its affiliates or agents may use the pricing supplement related to this free writing prospectus in market-making transactions after the initial sale of the Securities, but is under no obligation to make a market in the Securities and may discontinue any market-making activities at any time without notice.

We expect that delivery of the Securities will be made against payment for the Securities on or about the Settlement Date set forth on the inside cover page of this document, which is more than two business days following the Trade Date. Under Rule 15c6-1 under the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in two business days, unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Securities more than two business days prior to the Settlement Date will be required to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement, and should consult their own advisors.

See “Supplemental Plan of Distribution (Conflicts of Interest)” on page S-83 in the accompanying prospectus supplement.
