The Notes

HSBC Buffered Accelerated Market Participation Securities™ (Buffered AMPS™) offer investors an enhanced upside exposure to the upside return of the referenced indices, while providing a pre-defined level of downside buffered protection at maturity.

For investors who seek exposure to the Reference Asset and who believe the Reference Asset will appreciate over the term of the Buffered AMPS™, the Buffered AMPS™ provide an opportunity for accelerated returns (subject to a Maximum Cap). If the Reference Return is below the Buffer Percentage, then the Buffered AMPS™ are subject to 1:1 exposure to any potential decline of the relevant Reference Asset beyond -10.00%.

If the relevant Reference Asset appreciates over the term of the Notes, you will realize 200.00% (2.00x) of the relevant Reference Asset appreciation up to the relevant Maximum Cap. If the relevant Reference Asset declines, you will lose 1% of your investment for every 1% decline in the relevant Reference Asset beyond the -10.00% Buffer Percentage.

Information about each Reference Asset

The S&P 500® ESG Index ("SPXESUP") is designed to measure the performance of securities meeting sustainability criteria, while maintaining similar overall industry group weights as the S&P 500® Index. The SPXESUP is constructed from an eligible universe of stocks consisting of the stocks included in the S&P 500® Index. Eligible constituents are then excluded based on the four screens which target companies based on involvement with tobacco or controversial weapons and third-party provided ESG ratings.

The graph above sets forth the hypothetical back-tested performance of the SPXESUP from May 2, 2012 through January 27, 2019 and the historical performance of the SPXESUP from January 28, 2019 to April 29, 2022. The SPXESUP has been calculated by S&P Dow Jones Indices LLC only since January 28, 2019. The hypothetical back-tested performance of the SPXESUP above was calculated using the selection criteria and methodology employed to calculate the SPXESUP since its inception on January 28, 2019. The hypothetical back-tested SPXESUP data only reflects the application of that methodology in hindsight, since the SPXESUP was not actually calculated and published prior to January 28, 2019. The hypothetical back-tested SPXESUP data cannot completely account for the impact of financial risk in actual trading. There are numerous factors related to the equities markets in general that cannot be, and have not been, accounted for in the hypothetical back-tested SPXESUP data, all of which can affect actual performance. Consequently, you should not rely on that data as a reflection of what the actual SPXESUP performance would have been had the SPXESUP been in existence or in forecasting future SPXESUP performance. The graph above also reflects the actual SPXESUP performance from January 28, 2019 to April 29, 2022 based on information that we obtained from Bloomberg L.P. Any hypothetical or actual historical upward or downward trend in the level of the SPXESUP during any period shown is not an indication that the level of the SPXESUP is more or less likely to increase or decrease at any time during the term of the Notes.

The S&P 500® Index ("SPX") is a market capitalization-weighted index intended to provide a performance benchmark for the large-cap U.S. equity markets. The SPX includes a representative sample of 500 companies in leading industries of the U.S. economy.

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 graphs above illustrate the daily performance of the SPX and the RTY from May 2, 2012 through April 29, 2022. The closing values in the graphs above were obtained from the Bloomberg Professional® Service. Past performance is not necessarily an indication of future results.

For further information on each Reference Asset, please see “Description of the Reference Assets” beginning on page FWP-10 of this document. We have derived all disclosure regarding each Reference Asset from publicly available information. Neither HSBC USA Inc. nor any of its affiliates have undertaken any independent review of, or made any due diligence inquiry with respect to, the publicly available information about each Reference Asset.

RISK FACTORS

We urge you to read the section “Risk Factors” beginning on page S-1 of the accompanying prospectus supplement and page S-1 of the accompanying Equity Index 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 and the accompanying prospectus, prospectus supplement and relevant underlying supplement.

In addition to the risks discussed below, you should review “Risk Factors” in the accompanying prospectus supplement and relevant underlying supplement including the explanation of risks relating to the Notes described in the following sections:

“-Risks Relating to All Note Issuances” in the prospectus supplement; and

"-General Risks Related to Indices" in the Equity Index Underlying Supplement.

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 beyond the Buffer Percentage of -10.00%. Accordingly, if the relevant Reference Return is less than -10.00%, your Payment at Maturity will be less than the Principal Amount of your Notes. You will lose up to 90.00% of your investment at maturity if the relevant Reference Return is less than the Buffer Percentage.

The amount payable on the relevant Notes is not linked to the level of the relevant Reference Asset at any time other than on the Final Valuation Date.

The Final Value of the relevant Reference Asset will be based on the Official Closing Value of the relevant Reference Asset on the Final Valuation Date, subject to postponement for non-trading days and certain Market Disruption Events. Even if the value of the relevant Reference Asset 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 is less than the Initial Value, 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 relevant Reference Asset prior to such decrease. Although the actual value of the relevant Reference Asset 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 Value of the relevant Reference Asset on the Final Valuation Date.

The appreciation on the Notes is limited by the relevant Maximum Cap.

You will not participate in any appreciation in the value of the relevant Reference Asset (as multiplied by the Upside Participation Rate) beyond the relevant Maximum Cap. The Maximum Cap (to be determined on the Trade Date) will be at least 23.25% with respect to the Notes linked to the SPXESUP, at least 23.50% with respect to the Notes linked to the SPX and at least 26.00% with respect to the Notes linked to the RTY. You will not receive a return on the securities greater than the relevant Maximum Cap.

The Notes will not bear interest.

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

Risks Relating to the Reference Asset

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

We make no representation or assurance as to the environmental and social impact of the companies included in the SPXESUP.

We make no representation or assurance that the composition of the SPXESUP satisfies, whether in whole or in part, any present or future depositor expectations or requirements as regards any direct or indirect environmental and social impact of the businesses or products of companies included in the SPXESUP. If the environmental and social impact of the companies included in the SPXESUP is a factor in an investor's decision to invest in Notes linked to the SPXESUP, investors should consult with their legal or other advisers before making an investment in the Notes.

The SPXESUP may not be successful and may underperform alternative investment strategies.

There can be no assurance that the SPXESUP will achieve positive returns over any period. The components of the SPXESUP are selected from the constituents of the S&P 500® Index according to the methodology described below. The SPXESUP may underperform relative to the S&P 500® Index or equity markets generally, and the performance of the SPXESUP may be less favorable than alternative investment strategies that could have been implemented.

The SPXESUP follows a particular methodology, which may differ significantly from alternative approaches and investor expectations.

As described in the accompanying Equity Index Underlying Supplement, the SPXESUP follows a specific methodology developed by its sponsor, with determinations made by the sponsor as to which constituents of the S&P 500® Index will be selected as components of the SPXESUP. These determinations are also based on information provided by third-parties and scoring methodologies developed by the sponsor and third-parties. The SPXESUP methodology and the underlying score methodologies and may differ substantially from alternative strategies with similar objectives. Decisions to include or exclude components of the SPXESUP will be made solely by the sponsor, and such decisions will affect the performance of the SPXESUP on an ongoing basis. Additionally, the sponsor will make decisions regarding the stocks included in the SPXESUP at its own discretion, without regard to investor expectations. For example, the sponsor can exercise discretion in evaluating the severity of a controversy and determining whether to exclude a company after the publication of a Media and Stakeholder Analysis report. Similarly, any determinations made with respect to the underlying scores or data referenced by the sponsor, will be made without regard to investors. Neither we nor you will have any ability to affect decisions made regarding the SPXESUP or any underlying data, scores or methodologies. The SPXESUP may include components that differ significantly from alternative investments strategies with similar objectives and may underperform such alternative investment strategies, perhaps significantly.

The SPXESUP has a very limited operating history and may perform in unanticipated ways.

The SPXESUP was established on January 28, 2019 and therefore has little to no operating history. Because the SPXESUP is of recent origin and limited actual historical performance data exists with respect to it, your investment in the Notes may involve a greater risk than investing in securities linked to an index with a more established record of performance. Hypothetical back-tested performance prior to the launch of the Index provided in this document refers to simulated performance data created by applying the Index's calculation methodology to historical prices of the equities that comprise the SPXESUP. Such simulated performance data has been produced by the retroactive application of a back-tested methodology in hindsight, and may give more preference towards equities that have performed well in the past. Hypothetical back-tested results are neither an indicator or a guarantor of future results.

Small-Capitalization Risk.

The RTY tracks companies that are considered small-capitalization. These companies often have greater stock price volatility, lower trading volume and less liquidity than large-capitalization companies and therefore the level of the RTY may be more volatile than an investment in stocks issued by large-capitalization companies. Stock prices of small-capitalization companies are also more vulnerable than those of large-capitalization 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 typically 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. Such companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and less competitive strengths than large-capitalization companies and are more susceptible to adverse developments related to their products.

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 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. 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 value of the Reference Asset 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 3 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.

You will not have any ownership interest in the stocks included in a Reference Asset.

As a holder of the Notes, you will not have any ownership interest in the stocks included in a Reference Asset, such as rights to vote, dividend payments or other distributions. Because the return on the Notes will not reflect any dividends on those stocks, the Notes may underperform an investment in the stocks included in a Reference Asset.

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.

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 the relevant Reference Asset relative to its Initial Value.  We cannot predict the Final Value of the relevant Reference Asset.  The assumptions we have made in connection with the illustrations set forth below may not reflect actual events.  You should not take this illustration or these examples as an indication or assurance of the expected performance of the relevant Reference Asset to which your Notes are linked or the return on your Notes. With respect to the 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 those 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 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 Payment at Maturity 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 terms:

4	Principal Amount:	$1,000
4	Upside Participation Rate:	200.00%
4	Hypothetical Maximum Cap*:	23.25%
4	Buffer Percentage:	-10.00%

^* The actual Maximum Cap for each offering of Notes will be determined on the Pricing Date and with respect to the Notes linked to the SPXESUP will be at least 23.25%, with respect to the Notes linked to the SPX will be at least 23.50% and with respect to the Notes linked to the RTY will be at least 26.00%.

FWP-8

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

Example 1: The relevant Reference Return is 5.81%

Reference Return:	5.81%
Final Settlement Value:	$1,116.20

Because the relevant Reference Return is positive, and such Reference Return multiplied by the Upside Participation Rate is less than the hypothetical Maximum Cap, the Final Settlement Value would be $1,116.200 per $1,000 Principal Amount, calculated as follows:

        $1,000 + ($1,000 x Reference Return x Upside Participation Rate)

        = $1,000 + ($1,000 x 5.81% x 200.00%)

        = $1,116.20

Example 1 shows that you will receive the return of your principal investment plus a return equal to the Reference Return multiplied by the Upside Participation Rate when the Reference Asset appreciates and such Reference Return multiplied by the Upside Participation Rate does not exceed the hypothetical Maximum Cap.

Example 2: The relevant Reference Return is 17.44%

Reference Return:	17.44%
Final Settlement Value:	$1,232.50

Because the relevant Reference Return is positive, and such Reference Return multiplied by the Upside Participation Rate is greater than the hypothetical Maximum Cap, the Final Settlement Value would be $1,232.500 per $1,000 Principal Amount, calculated as follows:

        $1,000 + ($1,000 x Maximum Cap)

        = $1,000 + ($1,000 x 23.25%)

        = $1,232.50

Example 2 shows that you will receive the return of your principal investment plus a return equal to the hypothetical Maximum Cap when the relevant Reference Return is positive and such Reference Return multiplied by the Upside Participation Rate exceeds the hypothetical Maximum Cap.

Example 3: The relevant Reference Return is -5.00%

Reference Return:	-5.00%
Final Settlement Value:	$1,000.00

Because the relevant Reference Return is less than zero but greater than the Buffer Percentage of -10.00%, the Final Settlement Value would be $1,000.000 per $1,000 Principal Amount (a zero return).

Example 3 shows that you will receive the return of your principal investment where the value of the relevant Reference Asset declines by no more than 10.00% over the term of the Notes.

Example 4: The relevant Reference Return is -15.00%

Reference Return:	-15.00%
Final Settlement Value:	$950.00

Because the relevant Reference Return is less than the Buffer Percentage of -10.00%, the Final Settlement Value would be $950.000 per $1,000 Principal Amount, calculated as follows:

        $1,000 + [$1,000 x (Reference Return + 10.00%)]

        = $1,000 + [$1,000 x (-15.00% + 10.00%)]

        = $950.00

Example 4 shows that you are exposed on a 1-to-1 basis to declines in the value of the Reference Asset beyond the Buffer Percentage of -10.00%. You will lose some or a significant portion (up to 90.00%) of your investment.

DESCRIPTION OF THE REFERENCE ASSETS

For the Notes linked to the S&P 500® ESG Index The disclosure relating to the SPXESUP contained below relates only to the offering of Notes linked to the SPXESUP.
Description of the SPXESUP	Historical Performance of the SPXESUP
The S&P 500® ESG Index ("SPXESUP") is designed to measure the performance of securities meeting sustainability criteria, while maintaining similar overall industry group weights as the S&P 500® Index. The SPXESUP is constructed from an eligible universe of stocks consisting of the stocks included in the S&P 500® Index. Eligible constituents are then excluded based on the four screens which target companies based on involvement with tobacco or controversial weapons and third-party provided ESG ratings.   For more information about the SPXESUP, see "The S&P 500® ESG Index" beginning on page S-78 of the accompanying Equity Index Underlying Supplement.	The graph below sets forth the hypothetical back-tested performance of the SPXESUP from May 2, 2012 through January 27, 2019 and the historical performance of the SPXESUP from January 28, 2019 to April 29, 2022. The SPXESUP has been calculated by S&P Dow Jones Indices LLC only since January 28, 2019. The hypothetical back-tested performance of the SPXESUP set forth in the graph below was calculated using the selection criteria and methodology employed to calculate the SPXESUP since its inception on January 28, 2019. The hypothetical back-tested SPXESUP data only reflects the application of that methodology in hindsight, since the SPXESUP was not actually calculated and published prior to January 28, 2019. The hypothetical back-tested SPXESUP data cannot completely account for the impact of financial risk in actual trading. There are numerous factors related to the equities markets in general that cannot be, and have not been, accounted for in the hypothetical back-tested SPXESUP data, all of which can affect actual performance. Consequently, you should not rely on that data as a reflection of what the actual SPXESUP performance would have been had the SPXESUP been in existence or in forecasting future SPXESUP performance. The graph below also reflects the actual SPXESUP performance from January 28, 2019 to April 29, 2022 based on information that we obtained from Bloomberg L.P. Any hypothetical or actual historical upward or downward trend in the level of the SPXESUP during any period shown is not an indication that the level of the SPXESUP is more or less likely to increase or decrease at any time during the term of the Notes.
The historical values of the SPXESUP should not be taken as an indication of future performance, and no assurance can be given as to the Official Closing Level of the SPXESUP on the Final Valuation Date.

For the Notes linked to the S&P 500® Index The disclosure relating to the SPX contained below relates only to the offering of Notes linked to the SPX.
Description of the SPX	Historical Performance of the SPX
The S&P 500® Index ("SPX") is a market capitalization-weighted index intended to provide a performance benchmark for the large-cap U.S. equity markets. The SPX includes a representative sample of 500 companies in leading industries of the U.S. economy.   For more information about the SPX, see "The S&P 500® Index" beginning on page S-55 of the accompanying Equity Index Underlying Supplement.	The following graph sets forth the historical performance of the SPX based on the daily historical closing values from May 2, 2012 through April 29, 2022. 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.
The historical values of the SPX should not be taken as an indication of future performance, and no assurance can be given as to the Official Closing Level of the SPX on the Final Valuation Date.

For the Notes linked to the Russell 2000® Index The disclosure relating to the RTY contained below relates only to the offering of Notes linked to the RTY.
Description of the RTY	Historical Performance of the RTY
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.   For more information about the RTY, see "The Russell 2000® Index" beginning on page S-45 of the accompanying Equity Index Underlying Supplement.	The following graph sets forth the historical performance of the RTY based on the daily historical closing values from May 2, 2012 through April 29, 2022. 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.
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.

EVENTS OF DEFAULT AND ACCELERATION

If the relevant Notes have become immediately due and payable following an Event of Default (as defined in the accompanying prospectus) with respect to the relevant 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 of the relevant Reference Asset, 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 relevant Reference Asset on that scheduled trading day, then the accelerated Final Valuation Date for that 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.

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. With respect to the Notes linked to the SPXESUP, HSBC USA Inc. or one of our affiliates may pay varying underwriting discounts of up to 2.25% and referral fees of up to 1.00% per $1,000 Principal Amount in connection with the distribution of the Notes to other registered broker-dealers. In no case will the sum of the underwriting discounts and referral fees exceed 2.75% per $1,000 Principal Amount with respect to the Notes linked to the SPXESUP. With respect to the Notes linked to the SPX, HSBC USA Inc. or one of our affiliates may pay varying underwriting discounts of up to 2.25% and referral fees of up to 1.00% per $1,000 Principal Amount in connection with the distribution of the Notes to other registered broker-dealers. In no case will the sum of the underwriting discounts and referral fees exceed 2.75% per $1,000 Principal Amount with respect to the Notes linked to the SPX. With respect to the Notes linked to the RTY, HSBC USA Inc. or one of our affiliates may pay varying underwriting discounts of up to 2.25% and referral fees of up to 1.00% per $1,000 Principal Amount in connection with the distribution of the Notes to other registered broker-dealers. In no case will the sum of the underwriting discounts and referral fees exceed 2.75% per $1,000 Principal Amount with respect to the Notes linked to the RTY.

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.

FWP-11

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 relevant Reference Asset. 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 relevant Reference Asset. Pursuant to this approach 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 that you have held the Note for more than one year at such time for U.S. federal income tax purposes.

We will not attempt to ascertain whether any of the entities whose stock is included in the relevant Reference Asset would be treated as a passive foreign investment company ("PFIC") or United States real property holding corporation ("USRPHC"), both as defined for U.S. federal income tax purposes. If one or more of the entities whose stock is included in the relevant Reference Asset were so treated, certain adverse U.S. federal income tax consequences might apply. You should refer to information filed with the SEC and other authorities by the entities whose stock is included in the relevant Reference Asset and consult your tax advisor regarding the possible consequences to you if one or more of the entities whose stock is included in the relevant Reference Asset 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, 2023. 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 relevant Reference Asset 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 relevant Reference Asset 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.

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” in the accompanying prospectus supplement.

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