The Buffer Digital Notes (each a “Note” and collectively the “Notes") offered hereunder will not be listed on any securities exchange or automated quotation system. The Notes will not bear interest.

Neither the U.S. Securities and Exchange Commission (the “SEC”) nor any state securities commission has approved or disapproved of the Notes or passed upon the accuracy or the adequacy of this document, the accompanying prospectus, prospectus supplement, Equity Index Underlying Supplement or ETF Supplement. Any representation to the contrary is a criminal offense. We have appointed HSBC Securities (USA) Inc., an affiliate of ours, as the agent for the sale of the Notes. HSBC Securities (USA) Inc. will purchase the Notes from us for distribution to other registered broker-dealers or will offer the Notes directly to investors. In addition, HSBC Securities (USA) Inc. or another of its affiliates or agents may use the pricing supplement to which this document relates in market-making transactions in any Notes after their initial sale. Unless we or our agent inform you otherwise in the confirmation of sale, the pricing supplement to which this document relates is being used in a market-making transaction.

Information about the Reference Asset
The Nasdaq-100 Index® ("NDX") is a modified market capitalization-weighted index of 100 of the largest non-financial companies listed on the NASDAQ Stock Market based on market capitalization. It does not contain securities of financial companies (based on the Financials industry classification according to the Industry Classification Benchmark). Each underlying stock's influence on the level of the NDX is directly proportional to the value of its share weight.

The Russell 2000® Index (“RTY”) is designed to track the performance of the small capitalization segment of the U.S. equity market. All 2,000 stocks are traded on a major U.S. exchange, and the RTY consists of the smallest 2,000 companies included in the Russell 3000® Index. The Russell 3000® Index is composed of the 3,000 largest U.S. companies as determined by market capitalization.

The Utilities Select Sector SPDR® Fund (the "XLU") seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of publicly traded equity securities of companies in the utilities sector, as represented by the S&P® Financial Select Sector Index (the “IXU”). The IXU measures the performance of the utilities sector of the large-cap U.S. equity market. The IXU includes utility companies such as electric, gas and water utilities, independent power producers & energy traders and companies that engage in generation and distribution of electricity using renewable sources. Shares of the XLU are listed and trade on the NYSE Arca.

We reserve the right to change the terms of, or reject any offer to purchase, the Notes prior to their issuance. In the event of any material changes to the terms of the Notes, we will notify you.

PAYMENT AT MATURITY

On the Maturity Date, for each Note you hold, we will pay you the Final Settlement Value, which is an amount in cash, as described below:

If the Reference Return of the Least Performing Underlying is greater than or equal to the Buffer Percentage, you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount, calculated as follows:

$1,000 + ($1,000 × Digital Return).

If the Reference Return of the Least Performing Underlying is less than the Buffer Percentage, you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount, calculated as follows:

$1,000 + [$1,000 × (Reference Return of the Least Performing Underlying + 25.00%)].

Under these circumstances, you will lose 1% of the Principal Amount of your Notes for each percentage point that the Reference Return of the Least Performing Underlying is below the Buffer Percentage. For example, if the Reference Return of the Least Performing Underlying is -40.00%, you will suffer a 15.00% loss and receive 85.00% of the Principal Amount, subject to the credit risk of HSBC. You should be aware that if the Reference Return of the Least Performing Underlying is less than the Buffer Percentage, you will lose some or a significant portion (up to 75.00%) of your investment.

Interest

The Notes will not pay interest.

Calculation Agent

We or one of our affiliates will act as calculation agent with respect to the Notes.

Reference Sponsors

The reference sponsor of the NDX is Nasdaq Inc. The reference sponsor of the RTY is FTSE Russell. Select Sector SPDR Trust is the reference sponsor of the XLU.

INVESTOR SUITABILITY

RISK FACTORS

We urge you to read the section “Risk Factors” beginning on page S-1 of the accompanying prospectus supplement, page S-1 of the accompanying Equity Index Underlying Supplement and page S-1 of the accompanying ETF Underlying Supplement. You should understand the risks of investing in the Notes and should reach an investment decision only after careful consideration, with your advisors, of the suitability of the Notes in light of your particular financial circumstances and the information set forth in this document, the accompanying prospectus, prospectus supplement, Equity Index Underlying Supplement and ETF Underlying Supplement. In addition to the risks discussed below, you should review “Risk Factors” in the accompanying prospectus supplement, Equity Index Underlying Supplement and ETF Underlying Supplement including the explanation of risks relating to the Notes described in the following sections:

You will be subject to significant risks not associated with conventional fixed-rate or floating-rate debt securities.

Risks Relating to the Structure or Features of the Notes

Your investment in the Notes may result in a loss.

You will be exposed to the decline in the Final Value from the Initial Value of the Least Performing Underlying beyond the Buffer Percentage of -25.00%. Accordingly, if the Reference Return of the Least Performing Underlying is less than the Buffer Percentage of-25.00%, your Payment at Maturity will be less than the Principal Amount of your Notes. You will lose some or a significant portion (up to 75.00%) of your investment at maturity if the Reference Return of the Least Performing Underlying is less than the Buffer Percentage.

The appreciation on the Notes is limited by the Digital Return.

You will not participate in any appreciation in the level of the Least Performing Underlying beyond the Digital Return of 10.00%. You will not receive a return on the Notes greater than the Digital Return.

The amount payable on the Notes is not linked to the value of the Least Performing Underlying at any time other than on the Final Valuation Date.

The Final Value of the least Performing Underlying will be based on its Official Closing Level on the Final Valuation Date, subject to postponement for non-trading days and certain Market Disruption Events. Even if the value of the Least Performing Underlying appreciates during the term of the Notes other than on the Final Valuation Date but then decreases on the Final Valuation Date to a value that reflects a Reference Return that is less than the Buffer Percentage, the Payment at Maturity may be less, and may be significantly less, than it would have been had the Payment at Maturity been linked to the value of the Least Performing Underlying prior to such decrease. Although the actual value of the Least Performing Underlying on the Maturity Date or at other times during the term of the Notes may be higher than the Final Value, the Payment at Maturity will be based solely on the Official Closing Level of the Least Performing Underlying on the Final Valuation Date.

The Notes will not bear interest.

As a holder of the Notes, you will not receive interest payments.

Since the Notes are linked to the performance of more than one Underlying, you will be fully exposed to the risk of fluctuations in the value of each Underlying.

Since the Notes are linked to the performance of more than one Underlying, the Notes will be linked to the individual performance of each Underlying. Because the Notes are not linked to a basket, in which the risk is mitigated and diversified among all of the components of a basket, you will be exposed to the risk of fluctuations in the value of each Underlying. For example, in the case of notes linked to a basket, the return would depend on the aggregate performance of the basket components reflected as the basket return. Thus, the depreciation of any basket component could be mitigated by the appreciation of another basket component. However, in the case of these Notes, the individual performance of each of the Underlyings would not be combined to calculate your return and the depreciation of either Underlying would not be mitigated by the appreciation of the other Underlying. Instead, your return would depend on the Least Performing Underlying.

Because the Notes are linked to the performance of the Least Performing Underlying, you are exposed to greater risks of sustaining a significant loss on your investment than if the Notes were linked to just one Underlying. 

The risk that you will suffer a significant loss on your investment, is greater if you invest in the Notes as opposed to substantially similar securities that are linked to the performance of just one Underlying. With multiple Underlyings, it is more likely that the Reference Return of one of the Underlyings will be below the Buffer Percentage on the Final Valuation Date, than if the Notes were linked to only one Underlying. Therefore, it is more likely that you will suffer a significant loss on your investment.

Risks Relating to the Reference Asset

Changes that affect an Underlying may affect the value of an Underlying and the market value of the Notes and the amount you will receive on the Notes and the amount you will receive at maturity.

The policies of the reference sponsor of an Underlying concerning additions, deletions and substitutions of the stocks included in an Underlying, and the manner in which the reference sponsor takes account of certain changes affecting those stocks, may affect the value of an Underlying. The policies of the reference sponsor with respect to the calculation of an Underlying could also affect the value of an Underlying. The reference sponsor may discontinue or suspend calculation or dissemination of an Underlying. Any such actions could affect the value of an Underlying and the value of and the return on the Notes.

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.

Non-U.S. Securities Risk.

Some of the equity securities included in the NDX are issued by non-U.S. companies. Investments in securities linked to the value of such non-U.S. equity securities, such as the Notes, involve risks associated with the home countries of the issuers of those non-U.S. equity securities. The prices of securities in non-U.S. markets may be affected by political, economic, financial and social factors in those countries, or global regions, including changes in government, economic and fiscal policies and currency exchange laws.

General Risk Factors

The Notes are subject to the credit risk of HSBC USA Inc.

The Notes 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 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 return 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 Notes and, in the event HSBC were to default on its obligations, you may not receive the amounts owed to you under the terms of the Notes.

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 the full payments due on the Notes.

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 is expected to be less than the price to public.

The price to public takes into account certain costs. These costs, which will be used or retained by us or one of our affiliates, include the underwriting discount, our affiliates’ projected hedging profits (which may or may not be realized) for assuming risks inherent in hedging our obligations under the Notes and the costs associated with structuring and hedging our obligations under the Notes. 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 values of the Underlyings 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 we were to repurchase your Notes immediately after the Original Issue 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 Original Issue 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 6 months after the Original Issue 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 Original Issue Date of the Notes based on changes in market conditions and other factors that cannot be predicted.

The Notes lack liquidity.

The Notes will not be listed on any securities exchange or automated quotation system. HSBC Securities (USA) Inc. is not required to offer to purchase the Notes in the secondary market, if any exists. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Notes easily. 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 HSBC Securities (USA) Inc. is willing to buy the Notes.

Potential conflicts of interest may exist.

An affiliate of HSBC has a minority equity interest in the owner of an electronic platform, through which we may make available certain structured investments offering materials. HSBC and its affiliates play a variety of roles in connection with the issuance of the Notes, including acting as calculation agent and hedging our obligations under the Notes. In performing these duties, the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the Notes. We will not have any obligation to consider your interests as a holder of the Notes in taking any action that might affect the value of your Notes.

Uncertain tax treatment.

For a discussion of the U.S. federal income tax consequences of your investment in a Note, please see the discussion under “U.S. Federal Income Tax Considerations” herein and the discussion under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.

ILLUSTRATIVE EXAMPLES

The following table and examples 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 value of any Underlying relative to its Initial Value. We cannot predict the Final Value of an Underlying. The assumptions we have made in connection with the illustrations set forth below may not reflect actual events, and the hypothetical Initial Value used in the table and examples below is not expected to be the actual Initial Value of any Underlying. You should not take this illustration or these examples as an indication or assurance of the expected performance of the Underlyings or the return on your Notes. The Final Settlement Value may be less than the amount that you would have received from a conventional debt security with the same stated maturity, including such a security issued by HSBC. The numbers appearing in the table below and following examples have been rounded for ease of analysis.

The table below illustrates the Payment at Maturity on a $1,000 investment in the Notes for a hypothetical range of Reference Returns of the Least Performing Underlying from -100% to +100%. The following results are based solely on the assumptions outlined below. The “Hypothetical Return on the Notes” as used below is the number, expressed as a percentage, that results from comparing the Final Settlement Value per $1,000 Principal Amount to $1,000. The potential returns described here assume that your Notes are held to maturity. You should consider carefully whether the Notes are suitable to your investment goals. The following table and examples assume the following:

The hypothetical Initial Value of 1,000.00 used in the examples below has been chosen for illustrative purposes only and does not represent the actual Initial Value of any Underlying. The actual Initial Value of each Underlying will be determined on the Pricing Date.

The following examples indicate how the Final Settlement Value would be calculated with respect to a hypothetical $1,000 investment in the Notes.

Example 1: The value of the Least Performing Underlying increases from the Initial Value of 1,000.00 to a Final Value of 1,400.00.

RTY is the Least Performing Underlying.

Because the Reference Return of the Least Performing Underlying is positive, and the Reference Return of the Least Performing Underlying is greater than the Digital Return, the Final Settlement Value would be $1,100.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + ($1,000 × Digital Return)

= $1,000 + ($1,000 × 10.00%)

= $1,100.00

Example 1 shows that you will receive the return of your principal investment plus a return equal to the Digital Return when the Reference Return of the Least Performing Underlying is positive and such Reference Return of the Least Performing Underlying exceeds the Digital Return.

Example 2: The value of the Least Performing Underlying decreases from the Initial Value of 1,000.00 to a Final Value of 950.00.

RTY is the Least Performing Underlying.

Because the Reference Return of the Least Performing Underlying is greater than the Buffer Percentage of -25.00%, the Final Settlement Value would be $1,100.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + ($1,000 × Digital Return)

= $1,000 + ($1,000 × 10.00%)

= $1,100.00

Example 2 shows that as long as the Reference Return of the Least Performing Underlying is greater than the Buffer Percentage, you will receive the Digital Return.

Example 4: The value of the Least Performing Underlying decreases from the Initial Value of 1,000.00 to a Final Value of 500.00.

RTY is the Least Performing Underlying.

Because the Reference Return of the Least Performing Underlying is less than the Buffer Percentage of -25.00%, the Final Settlement Value would be $750.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + [$1,000 × (Reference Return of the Least Performing Underlying + 25.00%)]

= $1,000 + [$1,000 × (-50.00% + 25.00%)]

= $750.00

Example 3 shows that you are exposed on a 1-to-1 basis to declines in the value of the Least Performing Underlying if its Reference Return is beyond the Buffer Percentage of -25.00%. You will lose some or a significant portion (up to 75.00%) of your investment.

DESCRIPTION OF THE REFERENCE ASSET

The historical values of the NDX should not be taken as an indication of future performance, and no assurance can be given as to the Official Closing Level of the NDX on the Final Valuation Date.

The historical values of the RTY should not be taken as an indication of future performance, and no assurance can be given as to the Official Closing Level of the RTY on the Final Valuation Date.

Description of the XLU

We have derived all information contained in this document regarding the Utilities Select Sector SPDR^® Fund (the “XLU”), including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. Such information reflects the policies of, and is subject to change by the Select Sector SPDR^® Trust and SSGA Funds Management, Inc. (“SSFM”). Neither we nor any of our affiliates has undertaken any independent review or due diligence of such information. The XLU is an investment portfolio managed by SSFM, the investment adviser to the XLU. The XLU is an exchange-traded fund that trades on the NYSE Arca, Inc. under the ticker symbol “XLU.”

The Select Sector SPDR^® Trust is a registered investment company that consists of eleven separate investment portfolios (each, a “Select Sector SPDR^® Fund”), including the XLU. Each Select Sector SPDR^® Fund is an index fund that invests in a particular sector or group of industries represented by a specified Select Sector Index (together, the “Select Sector Indices”). The companies included in each Select Sector Index are selected on the basis of the Global Industry Classification Standard (GICS^®) from a universe of companies defined by the S&P 500^® Index (the “SPX”). The Select Sector Indices upon which the Select Sector SPDR^® Funds are based together comprise all of the companies in the SPX.

Information provided to or filed with the SEC by the Select Sector SPDR^® Trust pursuant to the Securities Act of 1933, as amended, and the Investment Company Act of 1940, as amended, can be located by reference to SEC file numbers 333-57791 and 811-08837, respectively, through the SEC’s website at http://www.sec.gov. Information from outside sources is not incorporated by reference in, and should not be considered a part of, this document. In addition, information may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. Neither we nor any of our affiliates has undertaken any independent review or due diligence of such information. You should undertake an independent investigation of the XLU as in your judgment is appropriate to make an informed decision with respect to an investment linked to the XLU.

Investment Objective

The XLU seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of publicly traded equity securities of companies in the utilities sector, as represented by the S&P^® Utilities Select Sector Index (the “IXU”). The IXU measures the performance of the utilities sector of the large-cap U.S. equity market. The IXU includes utility companies such as electric, gas and water utilities, independent power producers & energy traders and companies that engage in generation and distribution of electricity using renewable sources.

Investment Strategy — Replication

The XLU pursues the indexing strategy of “replication” seeking to track the performance of the IXU. The XLU will generally invest in all of the equity securities included in the IXU in approximately the same proportions as the IXU. There may, however, be instances where SSFM may choose to overweight a stock in the XLU compared to the IXU, purchase or sell securities not included in the IXU or utilize various combinations of other available investment techniques in seeking to track accurately the IXU. The XLU will normally invest at least 95% of its total assets in the securities that comprise the IXU. The XLU may invest its remaining assets in cash and cash equivalents or money market instruments, such as repurchase agreements and money market funds. Swaps, options and futures contracts, convertible securities and structured notes may be used by the XLU in seeking performance that corresponds to the IXU and in managing cash flows. The Board of Trustees of the Select Sector SPDR^® Trust may change the XLU’s investment strategy and other policies without shareholder approval.

Correlation

The IXU is a theoretical financial calculation, while the XLU is an actual investment portfolio. The return of the XLU may not match or achieve a high degree of correlation with the return of the IXU due to operating expenses, transaction costs, cash flows, regulatory requirements and operational inefficiencies.

Select Sector Index Capping Methodology

For reweighting purposes, the Select Sector Indices are rebalanced quarterly after the close of business on the third Friday of March, June, September and December using the following procedures:

If necessary, the reweighting process may take place more than once prior to the close on the last business day of March, June, September or December to ensure the Select Sector Indices conform to all diversification requirements.

When companies represented in the Select Sector Indices are represented by multiple share classes, maximum weight capping is based on company float-adjusted market capitalization, with the weight of multiple-class companies allocated proportionally to each share class based on its float-adjusted market capitalization as of the rebalancing reference date. If no capping is required, both share classes remain in the relevant Select Sector Index at their natural float-adjusted market capitalization.

Index Calculation, Maintenance and Governance

The Select Sector Indices are calculated, maintained and governed using the same methodology as the SPX, subject to the capping methodology described above. For additional information about the calculation, maintenance and governance of the SPX, see “—Description of the SPX” below.

Historical Performance of the XLU  

The following graph sets forth the historical performance of the XLU based on the daily historical closing values from October 2, 2013 through October 2, 2023. We obtained the closing values below from the Bloomberg Professional^® service. We have not undertaken any independent review of, or made any due diligence inquiry with respect to, the information obtained from the Bloomberg Professional^® service.    

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 in the same general manner as described in this document except that in such a case, the scheduled trading day immediately preceding the date of acceleration will be used as the Final Valuation Date for purposes of determining the Reference Return, and the accelerated Maturity Date will be three business days after the accelerated Final Valuation Date. If a Market Disruption Event exists with respect to the Reference Asset on that scheduled trading day, then the accelerated Final Valuation Date for the Reference Asset 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. For the avoidance of doubt, if no Market Disruption Event exists with respect to an Underlying on the scheduled trading day preceding the date of acceleration, the determination of such Underlying's Reference Return will be made on such date, irrespective of the existence of a Market Disruption Event with respect to any other Underlying occurring on such date.

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)

We have appointed HSBC Securities (USA) Inc., an affiliate of HSBC, as the agent for the sale of the Notes. Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc. will purchase the Notes from HSBC at the price to public less the underwriting discount set forth on the cover page of the pricing supplement to which this document relates, for distribution to other registered broker-dealers, or will offer the Notes directly to investors. HSBC Securities (USA) Inc. proposes to offer the Notes at the price to public set forth on the cover page of this document. HSBC USA Inc. or one of our affiliates may pay varying underwriting discounts of up to 0.65% per $1,000 Principal Amount in connection with the distribution of the Notes to other registered broker-dealers.

An affiliate of HSBC has paid or may pay in the future an amount to broker-dealers in connection with the costs of the continuing implementation of systems to support the Notes.

In addition, HSBC Securities (USA) Inc. or another of its affiliates or agents may use the pricing supplement to which this document relates 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.

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

We expect that delivery of the Notes will be made against payment for the Notes on or about the Original Issue 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 Notes more than two business days prior to the Original Issue 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.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

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 approach, a Note should be treated as a pre-paid executory contract with respect to the Underlyings. We intend to treat the Notes consistent with this approach. 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 the limitations described therein, and based on certain factual representations received from us, in the opinion of our special U.S. tax counsel, Mayer Brown LLP, it is reasonable to treat a Note as a pre-paid executory contract with respect to the Underlyings. Pursuant to this approach, and subject to the discussion below regarding “constructive ownership transactions,” we do not intend to report any income or gain with respect to the Notes prior to their maturity or an earlier sale or exchange and we intend to treat any gain or loss upon maturity or an earlier sale or exchange as long-term capital gain or loss, provided you have held the Note for more than one year at such time for U.S. federal income tax purposes. If the Notes are held by the same United States holder until maturity, that holder’s holding period will generally include the maturity date.

Despite the foregoing, U.S. holders (as defined under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement) should be aware that the Internal Revenue Code of 1986, as amended (the “Code”), contains a provision, Section 1260 of the Code, which sets forth rules which are applicable to what it refers to as “constructive ownership transactions.” Due to the manner in which it is drafted, the precise applicability of Section 1260 of the Code to any particular transaction is often uncertain. In general, a “constructive ownership transaction” includes a contract under which an investor will receive payment equal to or credit for the future value of any equity interest in a regulated investment company (such as shares of the XLU (the “Underlying Shares”)). Under the “constructive ownership” rules, if an investment in the Notes is treated as a “constructive ownership transaction,” any long-term capital gain recognized by a U.S. holder in respect of a Note will be recharacterized as ordinary income to the extent such gain exceeds the amount of “net underlying long-term capital gain” (as defined in Section 1260 of the Code) (the “Excess Gain”). In addition, an interest charge will also apply to any deemed underpayment of tax in respect of any Excess Gain to the extent such gain would have resulted in gross income inclusion for the U.S. holder in taxable years prior to the taxable year of the sale, exchange or maturity of the Note (assuming such income accrued at a constant rate equal to the applicable federal rate as of the date of sale, exchange or maturity of the Note). Furthermore, unless otherwise established by clear and convincing evidence, the “net underlying long-term capital gain” is treated as zero.

Although the matter is not clear, there exists a risk that an investment in the Notes will be treated as a “constructive ownership transaction.” If such treatment applies, it is not entirely clear to what extent any long-term capital gain recognized by a U.S. holder in respect of the Notes will be recharacterized as ordinary income. It is possible, for example, that the amount of the Excess Gain (if any) that would be recharacterized as ordinary income in respect of each Note will equal the excess of (i) any long-term capital gain recognized by the U.S. holder in respect of such a Note and attributable to the Underlying Shares over (ii) the “net underlying long-term capital gain” such U.S. holder would have had if such U.S. holder had acquired a number of the Underlying Shares at fair market value on the original issue date of such Note for an amount equal to the “issue price” of the Note allocable to the Underlying Shares and, upon the date of sale, exchange or maturity of the Note, sold such Underlying Shares at fair market value (which would reflect the percentage increase in the value of the Underlying Shares over the term of the Note). Accordingly, it is possible that all or a portion of any gain on the sale or settlement of the Notes after one year could be treated as “Excess Gain” from a “constructive ownership transaction,” which gain would be recharacterized as ordinary income, and subject to an interest charge. U.S. holders should consult their tax advisors regarding the potential application of the “constructive ownership” rules.

We will not attempt to ascertain whether any Underlying or any of the entities whose stock is included in an Underlying 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 any Underlying or one or more of the entities whose stock is included in an Underlying 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 any Underlying and the entities whose stock is included in an Underlying and consult your tax advisor regarding the possible consequences to you if any Underlying or one or more of the entities whose stock is included in any Underlying is or becomes a PFIC or a 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 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 an Underlying 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 an Underlying 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.
