HSBC USA Inc. Trigger Autocallable Contingent Yield Notes

$          Notes Linked to the Class A Common Stock of Lyft, Inc. due on or about May 27, 2025

Investment Description

These Trigger Autocallable Contingent Yield Notes (the ‘‘Notes’’) are senior unsecured debt securities issued by HSBC USA Inc. (“HSBC”) with returns linked to the Class A common stock of Lyft, Inc. (the “Reference Stock”). The Notes will rank equally with all of our other unsecured and unsubordinated debt obligations. HSBC will pay a quarterly Contingent Coupon if the Official Closing Price of the Reference Stock on the applicable Coupon Observation Date (including the Final Valuation Date) is equal to or greater than the Coupon Barrier. Otherwise, no coupon will be paid for the quarter. HSBC will automatically call the Notes if the Official Closing Price of the Reference Stock on any quarterly Call Observation Date, commencing on August 20, 2024, is equal to or greater than the Initial Price. If the Notes are called, HSBC will pay you the Principal Amount of your Notes plus the Contingent Coupon for the applicable quarter, and no further amounts will be owed to you under the Notes. If the Notes are not called prior to maturity and the Final Price is equal to or greater than the Downside Threshold, HSBC will pay you a cash payment at maturity equal to the Principal Amount of your Notes. If the Final Price is less than the Downside Threshold, HSBC will pay you less than the full Principal Amount, if anything, resulting in a loss on your initial investment that is proportionate to the negative performance of the Reference Stock over the term of the Notes, and you may lose up to 100% of your Principal Amount.

Investing in the Notes involves significant risks. HSBC may not pay any Contingent Coupons on the Notes. You may lose some or all of your Principal Amount. You will be exposed to the market risk of the Reference Stock on each Coupon Observation Date. Generally, the higher the Contingent Coupon Rate on a Note, the greater the risk of loss on that Note. The contingent repayment of principal only applies if you hold the Notes to maturity. Any payment on the Notes, including any repayment of principal, 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 Notes and you could lose your entire investment.

Features

❑  Contingent Coupon: HSBC will pay a quarterly Contingent Coupon payment if the Official Closing Price of the Reference Stock on the applicable Coupon Observation Date is equal to or greater than the Coupon Barrier. Otherwise, no coupon will be paid for the quarter.

❑  Automatically Callable: HSBC will automatically call the Notes and pay you the Principal Amount of your Notes plus the Contingent Coupon otherwise due for that applicable quarter if the Official Closing Price of the Reference Stock on any quarterly Call Observation Date, commencing on August 20, 2024, is equal to or greater than the Initial Price. If the Notes are not called, investors will potentially lose a portion of their Principal Amount at maturity.

❑  Contingent Repayment of Principal Amount at Maturity: If the Notes have not been previously called and the Final Price of the Reference Stock is not less than the Downside Threshold on the Final Valuation Date, HSBC will pay you the Principal Amount per Note at maturity. If the Final Price of the Reference Stock on the Final Valuation Date is less than the Downside Threshold, HSBC will pay a cash amount that is less than the Principal Amount, if anything, resulting in a loss on your initial investment that is proportionate to the decline in the Official Closing Price of the Reference Stock from the Pricing Date to the Final Valuation Date. The contingent repayment of principal only applies if you hold the Notes until maturity. Any payment on the Notes, including any repayment of principal, is subject to the creditworthiness of HSBC.

THE NOTES ARE SIGNIFICANTLY RISKIER THAN CONVENTIONAL DEBT INSTRUMENTS. THE TERMS OF THE NOTES MAY NOT OBLIGATE HSBC TO REPAY THE FULL PRINCIPAL AMOUNT OF THE NOTES. THE NOTES CAN HAVE DOWNSIDE MARKET RISK SIMILAR TO THE REFERENCE STOCK, 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 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 7 AND THE MORE DETAILED ‘‘RISK FACTORS’’ BEGINNING ON PAGE S-1 OF THE ACCOMPANYING STOCK-LINKED UNDERLYING SUPPLEMENT AND BEGINNING ON PAGE S-1 OF THE ACCOMPANYING PROSPECTUS SUPPLEMENT BEFORE PURCHASING ANY NOTES. 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 fully understand the risks inherent in an investment in the Notes, including the risk of loss of your entire initial investment.

¨ You believe the price of the Reference Stock will be equal to or greater than the Coupon Barrier on most or all of the Coupon Observation Dates and equal to or greater than the Downside Threshold on the Final Valuation Date.

¨ 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 have the same downside market risk as the Reference Stock.

¨ You understand and accept that you will not participate in any appreciation in the price of the Reference Stock, and your potential return is limited to the Contingent Coupon payments.

¨ You are willing to invest in the Notes based on the Coupon Barrier and Downside Threshold indicated on the cover hereof.

¨ You are willing to hold Notes that may be automatically called on any Call Observation Date on which the Official Closing Price of the Reference Stock is equal to or greater than the Initial Price, or you are otherwise willing to hold the Notes 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 Notes versus a conventional debt security with a comparable maturity issued by HSBC or another issuer with a similar credit rating.

¨ You are willing to forgo dividends paid on the Reference Stock and do not seek guaranteed current income from your investment.

The Notes may not be suitable for you if:

¨ You do not fully understand the risks inherent in an investment in the Notes, including the risk of loss of your entire initial investment.

¨ You are unwilling to invest in the Notes based on the Coupon Barrier and Downside Threshold indicated on the cover hereof.

¨ You are unable or unwilling to hold securities that will be automatically called on any Call Observation Date on which the Official Closing Price of the Reference Stock is equal to or greater than the Initial Price, or you are otherwise unable or unwilling to hold the Notes 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 prefer to receive the dividends paid on the Reference Stock and seek guaranteed current income from your investment.

¨ You are not willing or are unable to assume the credit risk associated with HSBC, as Issuer of the Notes, for any payments on the Notes, including any repayment of principal.

Investment Timeline

	The Initial Price was observed.
	The terms of the Notes are determined.
	If the Official Closing Price of the Reference Stock is equal to or greater than the Coupon Barrier on any Coupon Observation Date, HSBC will pay you a Contingent Coupon on the applicable Coupon Payment Date. The Notes will automatically be called if the Official Closing Price of the Reference Stock on any Call Observation Date, commencing on August 20, 2024, is equal to or greater than the Initial Price. If the Notes are called, HSBC will pay you a cash payment per Note equal to $10.00 plus the Contingent Coupon otherwise due on that date.
	The Final Price and Reference Stock Return of the Reference Stock are determined on the Final Valuation Date. If the Notes have not been called and the Final Price is equal to or greater than the Downside Threshold, HSBC will repay the Principal Amount equal to $10.00 per Note. If the Notes have not been called and the Final Price is below the Downside Threshold, HSBC will pay you a cash payment at maturity that will be less than the Principal Amount, if anything, resulting in a loss of principal proportionate to the decline of the Reference Stock, equal to a return of: $10 × (1 + Reference Stock Return) per Note

INVESTING IN THE NOTES INVOLVES SIGNIFICANT RISKS. YOU MAY LOSE SOME OR ALL OF YOUR PRINCIPAL AMOUNT. ANY PAYMENT ON THE NOTES, INCLUDING ANY REPAYMENT OF PRINCIPAL, 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 NOTES AND YOU COULD LOSE YOUR ENTIRE INVESTMENT.

You will be exposed to the market risk of the Reference Stock on each Coupon Observation Date. Generally, the higher the Contingent Coupon Rate on a Note, the greater the risk of loss on that Note.

Key Risks

An investment in the Notes involves significant risks. Some of the risks that apply to the Notes are summarized here. However, HSBC urges you to read the more detailed explanation of risks relating to the Notes generally in the “Risk Factors” section of the accompanying stock-linked underlying supplement and the accompanying prospectus supplement. HSBC also urges you to consult your investment, legal, tax, accounting and other advisors before you invest in the Notes.

Risks Relating to the Structure or Features of the Notes

¨ Risk of Loss at Maturity — The Notes differ from ordinary debt securities in that HSBC will not necessarily pay the full Principal Amount of the Notes. If the Notes are not called, HSBC will only pay you the Principal Amount of your Notes in cash if the Final Price is greater than or equal to the Downside Threshold, and will only make that payment at maturity. If the Notes are not called and the Final Price is less than the Downside Threshold, you will lose some or all of your initial investment in an amount proportionate to the decline in the Final Price from the Initial Price. You may lose some or all of your Principal Amount at maturity.

¨ The Contingent Repayment of Principal Applies at Maturity — You should be willing to hold your Notes to maturity. If you are able to sell your Notes prior to maturity in the secondary market, you may have to sell them at a loss relative to your initial investment even if the price of the Reference Stock at that time is above the Downside Threshold.

¨ You May Not Receive any Contingent Coupons — HSBC will not necessarily make periodic coupon payments on the Notes. If the Official Closing Price of the Reference Stock on a Coupon Observation Date is less than the Coupon Barrier, HSBC will not pay you the Contingent Coupon applicable to that Coupon Observation Date. If the Official Closing Price of the Reference Stock is less than the Coupon Barrier on each of the Coupon Observation Dates, HSBC will not pay you any Contingent Coupons during the term of, and you will not receive a positive return on, your Notes. Generally, this non-payment of the Contingent Coupon coincides with a period of greater risk of principal loss on your Notes.

¨ Higher Contingent Coupons or Lower Downside Thresholds Are Generally Associated with an Reference Stock with Greater Expected Volatility and Therefore Can Indicate a Greater Risk of Loss —"Volatility" refers to the frequency and magnitude of changes in the price of an Reference Stock. The greater the expected volatility with respect to an Reference Stock on the Trade Date, the higher the expectation as of the Trade Date that the Reference Stock could close below the Coupon Barrier on a Coupon Observation Date, resulting in no Contingent Coupons payable on the Notes, or below the Downside Threshold on the Final Valuation Date, resulting in the loss of some or all of your investment. This greater expected risk will generally be reflected in a higher Contingent Coupon than the yield payable on our conventional debt securities with a similar maturity, or in more favorable terms (such as a lower Downside Threshold or a higher Contingent Coupon) than for similar securities linked to the performance of an Reference Stock with a lower expected volatility as of the Trade Date. You should therefore understand that a relatively higher Contingent Coupon may indicate an increased risk of loss. Further, a relatively lower Downside Threshold may not necessarily indicate that the Notes have a greater likelihood of a repayment of principal at maturity. The volatility of an Reference Stock can change significantly over the term of the Notes. The price of the Reference Stock for your Notes could fall sharply, which could result in a significant loss of principal, and the non-payment of one or more Contingent Coupons. You should be willing to accept the downside market risk of the Reference Stock and the potential to lose some or all of your principal at maturity.

¨ Limited Return on the Notes — The return potential of the Notes is limited to the Contingent Coupon Rate regardless of any appreciation of the Reference Stock. In addition, your total return on the Notes will vary based on the number of Coupon Observation Dates for which the Contingent Coupons are payable and may be less than the Contingent Coupon Rate, or even zero. Further, the return potential of the Notes is limited by the automatic call feature in that you will not receive any further payments after the Notes are called. Your Notes could be called as early as August 20, 2024, and your return could be minimal. If the Notes are not called, you may be exposed to the decline in the price of the Reference Stock even though you cannot participate in any potential appreciation in the price of the Reference Stock. In addition, if the Notes have not been previously called and if the price of the Reference Stock is less than the Initial Price, as the Maturity Date approaches and the remaining number of Coupon Observation Dates decreases, the Notes are less likely to be automatically called, as there will be a shorter period of time remaining for the price of the Reference Stock to increase to the Initial Price. As a result, the return on an investment in the Notes could be less than the return on a direct investment in securities represented by the Reference Stock.

¨ The Amount Payable on the Notes Is Not Linked to the Price of the Reference Stock at Any Time Other Than on the Coupon Observation Dates, Including the Final Valuation Date — The return on the Notes will be based on the Official Closing Price of the Reference Stock on the Coupon Observation Dates, subject to postponement for non-trading days and certain Market Disruption Events. Even if the price of the Reference Stock appreciates prior to the applicable Call Observation Date or Coupon Observation Date but then drops on that day to a price that is less than the Initial Price or Coupon Barrier, the Notes will not be called, the Contingent Coupon may not be payable, and the return on the Notes will be less, and may be significantly less, than it would have been had the Notes been linked to the price of the Reference Stock prior to such decrease. Although the actual price of the Reference Stock on the Maturity Date or at other times during the term of the Notes may be higher than its Official Closing Price on any Coupon Observation Date, the return on the Notes will be based solely on the Official Closing Price of the Reference Stock on the applicable Coupon Observation Dates, including the Final Valuation Date.

Risks Relating to the Reference Stock

¨ Single Stock Risk – The price of the Reference Stock can rise or fall sharply due to factors specific to that Reference Stock and its issuer, such as stock price volatility, earnings, financial conditions, corporate, industry and regulatory developments, management changes and decisions and other events, as well as general market factors, such as general stock market volatility and levels, interest rates and economic and political conditions. For additional information about the Reference Stock and their issuers, please see “Information About the Reference Stock” in this free writing prospectus and the issuers’ SEC filings referred to in those sections.

General Risk Factors

¨ The Estimated Initial Value of the Notes, 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 Notes in the Secondary Market, if Any — The Estimated Initial Value of the Notes 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 Notes. 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 Notes 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 Notes to be more favorable to you. We will determine the value of the embedded derivatives in the Notes 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 Notes 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 Notes in the secondary market (if any exists) at any time.

¨ The Price of Your Notes in the Secondary Market, if Any, Immediately After the Trade Date Will 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 Notes, the underwriting discount and the costs associated with structuring and hedging our obligations under the Notes. 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 Notes in the secondary market, if any, the price you would receive for your Notes 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 Notes in the secondary market, if any, at any time after issuance will vary based on many factors, including the price of the Reference Stock and changes in market conditions, and cannot be predicted with accuracy. The Notes are not designed to be short-term trading instruments, and you should, therefore, be able and willing to hold the Notes to maturity. Any sale of the Notes prior to maturity could result in a loss to you.

¨ If One of Our Affiliates Were to Repurchase Your Notes Immediately After the Settlement Date, the Price You Receive May Be Higher than the Estimated Initial Value of the Notes — 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 Notes 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 Notes and other costs in connection with the Notes that we will no longer expect to incur over the term of the Notes. 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 Notes and any agreement we may have with the distributors of the Notes. 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 Notes based on changes in market conditions and other factors that cannot be predicted.

¨ Reinvestment Risk — If your Notes are called early, the term of the Notes will be reduced and you will not receive any payment on the Notes after the applicable Call Settlement Date. There is no guarantee that you would be able to reinvest the proceeds from an automatic call of the Notes at a comparable rate of return for a similar level of risk. To the extent you are able to reinvest such proceeds in an investment comparable to the Notes, you may incur transaction costs. The Notes may be called as early as approximately 3 months after issuance.

¨ The Notes Are Subject to the Credit Risk of the Issuer — The Notes are senior unsecured debt obligations of 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 Notes 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 Notes, including any Contingent Coupon payment or any repayment of principal at maturity or upon an automatic call, 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 Notes 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 Notes and could lose your entire investment.

¨ No Assurance that the Return Strategy of the Notes Will Be Successful — While the Notes are structured to provide Contingent Coupons as long as the Official Closing Price of the Reference Stock on the relevant Coupon Observation Date does not decline below the Coupon Barrier, we cannot assure you of the economic environment during the term of the Notes, or at maturity. As a result, you may not receive a Contingent Coupon on any Coupon Payment Date, and you may lose some or all of your initial investment in the Notes.

¨ Lack of Liquidity — The Notes will not be listed on any securities exchange or quotation system. One of HSBC’s affiliates intends to offer to purchase the Notes 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 Notes, the price at which you may be able to trade your Notes is likely to depend on the price, if any, at which one of HSBC’s affiliates is willing to buy the Notes, and therefore you may have to sell your Notes at a significant discount.

¨ Owning the Notes Is Not the Same as Owning the Reference Stock – The return on your Notes may not reflect the return you would realize if you actually owned the Reference Stock. As a holder of the Notes, you will not have voting rights or rights to receive dividends or other distributions or other rights that holders of the Reference Stock would have, unless you receive shares of that Reference Stock as payment on the Notes at maturity. Furthermore, the Reference Stock may appreciate substantially during the term of your Notes, and you will not participate in that appreciation.

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

¨ Potential HSBC and UBS Financial Services Inc. Impact on the Reference Stock — Trading or transactions by HSBC, UBS Financial Services Inc., or any of their respective affiliates in the Reference Stock or in futures, options, exchange-traded funds or other derivative products on the Reference Stock, may adversely affect the price of the Reference Stock, and, therefore, the market value of your Notes.

¨ Potential Conflicts of Interest — HSBC, UBS Financial Services Inc., or any of their respective affiliates may engage in business with the issuers of the Reference Stock, which may present a conflict between the obligations of HSBC or UBS Financial Services Inc., and you, as a holder of the Notes. HSBC, as the Calculation Agent, will determine on each applicable Coupon Observation Date whether the Contingent Coupon is to be paid, and whether the Notes are to be called, based on the Official Closing Price of the Reference Stock. The Calculation Agent can postpone the determination of the Official Closing Price on a Coupon Observation Date and the corresponding Coupon Payment Date or Call Settlement Date, as applicable, if a Market Disruption Event exists on that Coupon Observation Date. Furthermore, the Calculation Agent can postpone the determination of the Final Price and the Maturity Date if a Market Disruption Event occurs and is continuing on the Final Valuation Date.

¨ Economic and Market Factors Affecting the Terms and Market Price Prior to Maturity or Call — Because structured notes, including the Notes, 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 Notes at issuance and the market price of the Notes prior to maturity or call. These factors include the price of the Reference Stock; the volatility of the Reference Stock; the dividend rate paid on the Reference Stock; the time remaining to the maturity of the Notes; 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.

¨ The Notes Are Not Insured or Guaranteed by any Governmental Agency of the United States or any Other Jurisdiction —The Notes 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 Notes is subject to the credit risk of HSBC, and in the event that HSBC is unable to pay its obligations as they become due, you may not receive any amount owed to you under the Notes and could lose your entire investment.

¨ There Is Limited Anti-dilution Protection – The Calculation Agent will adjust the Official Closing Price for certain events affecting the Reference Stock, such as stock splits and corporate actions. These adjustments may impact whether the Notes are called and the Payment at Maturity. The Calculation Agent is not required to make an adjustment for every corporate action which affects the Reference Stock. If an event occurs that does not require the Calculation Agent to adjust the price of the Reference Stock, the market price of the Notes, and the payments on the Notes, may be materially and adversely affected. See “Additional Terms of the Notes—Antidilution and Reorganization Adjustments” in the accompanying stock-linked underlying supplement.

¨ In Some Circumstances, the Payment You Receive on the Notes May Be Based on the Stock of Another Company and Not the Reference Stock – Following certain corporate events relating to the issuer of the Reference Stock where such issuer is not the surviving entity, the amount of cash that you will receive on the Notes may be based on the stock of a successor to the Reference Stock issuer or any cash or any other assets distributed to holders of the Reference Stock in such corporate event. The occurrence of these corporate events and the consequent adjustments may materially and adversely affect the value of the Notes. For more information, see the section “Additional Terms of the Notes—Merger Event and Tender Offer” beginning on page S-10 of the accompanying stock-linked underlying supplement.

¨ Uncertain Tax Treatment — There is no direct legal authority as to the proper tax treatment of the Notes, and therefore significant aspects of the tax treatment of the Notes are uncertain as to both the timing and character of any inclusion in income in respect of the Notes. Under one reasonable approach, the Notes should be treated as contingent income-bearing pre-paid executory contracts with respect to the Reference Stock. HSBC intends to treat the Notes consistent with this approach and pursuant to the terms of the Notes, you agree to treat the Notes under this approach for all 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 contingent income-bearing pre-paid executory contracts.

In addition, the Notes are not intended for purchase by any investor that is not a United States person, as that term is defined for U.S. federal income tax purposes, and the underwriters will not make offers of the Notes to any such investor. If, however, a Note is transferred to a non-U.S. holder (as defined in the accompanying prospectus supplement) in the secondary market, because the tax treatment of the Contingent Coupons is unclear, such non-U.S. holder may be subject to 30% withholding tax applicable to any Contingent Coupon, subject to reduction or elimination by applicable treaty, unless income from such Contingent Coupon is effectively connected with your conduct of a trade or business within the United States. HSBC will not pay any additional amounts in respect of such withholding.

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 Notes) should be required to accrue income during its

9

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 a Note is required to accrue income in respect of the Notes prior to the receipt of payments with respect to the Notes 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 Notes as ordinary income (including gain on a sale). Finally, it is possible that a non-U.S. holder of the Notes could be subject to U.S. withholding tax in respect of the Notes. It is unclear whether any regulations or other guidance would apply to the Notes (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 Notes.

For a more complete discussion of the U.S. federal income tax consequences of your investment in a Note, please see the discussion under “What Are the Tax Consequences of the Notes?” in this document and the discussion under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.

Hypothetical Scenario Analysis and Examples at Maturity

The scenario analysis and examples below are hypothetical and provided for illustrative purposes only. They do not purport to be representative of every possible scenario concerning increases or decreases in the price of the Reference Stock relative to the Initial Price. The hypothetical terms used below are not the actual terms. 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 Price or the Official Closing Price of the Reference Stock on any Coupon Observation Date or Call Observation Date. You should not take the scenario analysis and these examples as an indication or assurance of the expected performance of the Reference Stock. The numbers appearing in the examples below may have been rounded for ease of analysis. The following scenario analysis and examples illustrate the Payment at Maturity or upon earlier automatic call per $10.00 Note on a hypothetical offering of the Notes, based on the following assumptions:

Investment term:	Approximately 1 year (unless earlier called)
Hypothetical Initial Price:	$100
Contingent Coupon Rate:	20.15% per annum (or 5.0375% per quarter)
Contingent Coupon:	$0.50375 per quarter
Coupon Observation Dates:	Quarterly
Call Observation Dates:	Quarterly, commencing on August 20, 2024
Hypothetical Coupon Barrier:	$50.00 (50.00% of the Initial Price)
Hypothetical Downside Threshold:	$50.00 (50.00% of the Initial Price)

Example 1 — Notes are Called on the First Call Observation Date, Which Corresponds to the First Coupon Observation Date

Date	Official Closing Price	Payment (per Security)
First Coupon Observation Date (First Call Observation Date)	$80 (at or above Coupon Barrier and below Initial Price)	$0.50375 (Contingent Coupon) – Notes are not automatically called
Second Coupon Observation Date (Second Call Observation Date)	$120 (at or above Coupon Barrier and Initial Price)	$11.0075 (Settlement Amount)
	Total Payment: $11.0075 (10.075% return)

Since the Notes are called on the second Coupon Observation Date (which is the second Call Observation Date), HSBC will pay you on the Call Settlement Date a total of $11.0075 per Note, reflecting your Principal Amount plus the applicable Contingent Coupon, for a 10.075% total return on the Notes. No further amount will be owed to you under the Notes.

Example 2 — Notes are NOT Called and the Final Price Is at or Above the Coupon Barrier and Downside Threshold

Date	Official Closing Price	Payment (per Security)
First Coupon Observation Date	$90 (at or above Coupon Barrier; below Initial Price)	$0.50375 (Contingent Coupon) – Notes are not automatically called
Second and Third Coupon Observation Dates	Various (at or above Coupon Barrier; below Initial Price)	$1.0075
Final Valuation Date	$85 (at or above Coupon Barrier and Downside Threshold; below Initial Price)	$10.50375 (Payment at Maturity)
	Total Payment: $12.015 (20.15% return)

At maturity, HSBC will pay you a total of $10.50375 per Note, reflecting your Principal Amount plus the applicable Contingent Coupon. When added to the Contingent Coupon payments of $1.0075 received in respect of the first through third Coupon Observation Dates, HSBC will have paid you a total of $12.015 per Note, for a 20.15% total return on the Notes.

11

Example 3 — Notes are NOT Called and the Final Price is below the Downside Threshold (and Coupon Barrier)

Date	Official Closing Price	Payment (per Security)
First Coupon Observation Date	$90 (at or above Coupon Barrier; below Initial Price)	$0.50375 (Contingent Coupon) – Notes are not automatically called
Second and Third Coupon Observation Dates	Various (below Coupon Barrier; below Initial Price)	$0.00
Final Valuation Date	$40 (below Coupon Barrier and Downside Threshold)	$10.00 × (1 + Reference Stock Return) =$10.00 × (1 + -60%) =$10.00 - $6.00 =$4.00 (Payment at Maturity)
	Total Payment: $4.50375 (-54.9625% return)

Since the Notes are not called and the Final Price is below the Downside Threshold, HSBC will pay you at maturity $4.00 per Note. In addition, the final Contingent Coupon will not be payable because the Final Price is also below the Coupon Barrier. When added to the Contingent Coupon payments of $0.50375 received in respect of the first Coupon Observation Date, HSBC will have paid you $4.50375 per Note, for a -54.9625% total return on the Notes.

What Are the Tax Consequences of the Notes?

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 the Notes. 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 Notes. Under one reasonable approach, the Notes should be treated as contingent income-bearing pre-paid executory contracts with respect to the Reference Stock. HSBC intends to treat the Notes consistent with this approach, and pursuant to the terms of the Notes, you agree to treat the Notes 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 Notes in accordance with this approach. Pursuant to this approach, HSBC intends to treat any gain or loss upon maturity or an earlier sale, exchange or call as capital gain or loss in an amount equal to the difference between the amount you receive at such time (other than with respect to a Contingent Coupon) and your tax basis in the Note. Any such gain or loss will be long-term capital gain or loss if you have held the Note for more than one year at such time for U.S. federal income tax purposes. Your tax basis in a Note generally will equal your cost of the Note. In addition, the tax treatment of the Contingent Coupons is unclear. Although the tax treatment of the Contingent Coupons is unclear, HSBC intends to treat any Contingent Coupon paid by HSBC, including on the Maturity Date or upon automatic call, as ordinary income includible in income by you at the time it accrues or is received in accordance with your normal method of accounting 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 Executory Contracts” in the accompanying prospectus supplement for the U.S. federal income tax considerations applicable to securities that are treated as contingent income-bearing pre-paid executory contracts.

The Notes are not intended for purchase by any investor that is not a United States person, as that term is defined for U.S. federal income tax purposes, and the underwriters will not make offers of the Notes to any such investor. If, however, a Note is transferred to a non-U.S. holder in the secondary market, because the tax treatment of the Contingent Coupons is uncertain, the entire amount of the Contingent Coupons will be subject to U.S. federal income tax withholding at a 30% rate (or at a lower rate under an applicable income tax treaty), unless the income from such Contingent Coupon is effectively connected with your conduct of a trade or business within the United States. We will not pay any additional amounts in respect of such withholding. In order to claim an exemption from or a reduction in the 30% withholding tax, a non-U.S. holder of the Notes must comply with certification requirements to establish that it is not a U.S. person and is eligible for a reduction of, or an exemption from, withholding under an applicable tax treaty. If you are a non-U.S. holder, you should consult your tax advisors regarding the tax treatment of the Notes, including the possibility of obtaining a refund of any withholding tax and the certification requirement described above.

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 Notes, other characterizations and treatments are possible and the timing and character of income in respect of the Notes might differ materially and adversely from the treatment described above. For example, Notes that have a term of one year or less could be treated as short-term 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 — Short-Term Notes” in the accompanying prospectus supplement. Notes that have a term of more than one year 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 accompanying prospectus supplement.

In Notice 2008-2, the 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 Notes) 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 of a Note is required to accrue income in respect of the Notes prior to the receipt of payments with respect to the Notes 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 Notes as ordinary income (including gain on a sale). Finally, it is possible that a non-U.S. holder of the Notes could be subject to U.S. withholding tax in respect of the Notes. It is unclear whether any regulations or other guidance would apply to the Notes (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 Notes.

We will not attempt to ascertain whether the Reference Stock 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 the Reference Stock 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 Reference Stock and consult your tax advisor regarding the possible consequences to you if the Reference Stock 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 Notes are likely to be

14

treated as U.S. situs property, subject to U.S. federal estate tax. These individuals and entities should consult their own tax advisors regarding the U.S. federal estate tax consequences of investing in the Notes.

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, Internal Revenue Service 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 Notes are not “delta-one” instruments, non-U.S. holders should not be subject to withholding on dividend equivalent payments, if any, under the Notes. However, it is possible that the Notes could be treated as deemed reissued for U.S. federal income tax purposes upon the occurrence of certain events affecting the Reference Stock or the Notes, and following such occurrence the Notes 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 Stock or the Notes should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the Notes 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 NOTES SHOULD CONSULT THEIR TAX ADVISORS AS TO THE U.S. FEDERAL, STATE, LOCAL, AND OTHER TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF NOTES.

Events of Default and Acceleration

If the Notes have become immediately due and payable following an Event of Default (as defined in the accompanying prospectus) with respect to the Notes, the Calculation Agent will determine the accelerated payment due and payable at maturity in the same general manner as described herein, except that the scheduled trading day immediately preceding the date of acceleration will be used as the Final Valuation Date for the purposes of determining the Final Price and if a Contingent Coupon is payable. If a Market Disruption Event exists with respect to the Reference Stock on that scheduled trading day, then the accelerated Final Valuation Date for the Reference Stock 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 Notes have become immediately due and payable following an Event of Default, you will not be entitled to any additional payments with respect to the Notes. 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 Notes 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 Notes 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 Notes 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 UBS Financial Services Inc., in connection with the sale of the Notes and UBS Financial Services Inc. 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 Notes, but is under no obligation to make a market in the Notes and may discontinue any market-making activities at any time without notice.

We expect that delivery of the Notes will be made against payment for the Notes on or about the Settlement Date set forth on the 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 Notes 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-87 in the accompanying prospectus supplement.
