GENERAL

This document relates to an offering of Notes linked to the Reference Asset. The purchaser of a Note will acquire a senior unsecured debt security of HSBC USA Inc. Although the offering of Notes relates to the Reference Asset, you should not construe that fact as a recommendation as to the merits of acquiring an investment linked to the Reference Asset or any component security included in the Reference Asset or as to the suitability of an investment in the Notes.

You should read this document together with the prospectus dated February 23, 2021, the prospectus supplement dated February 23, 2021 and the Equity Index Underlying Supplement dated February 23, 2021. If the terms of the Notes offered hereby are inconsistent with those described in the accompanying prospectus, prospectus supplement or Equity Index Underlying Supplement, the terms described in this document shall control. You should carefully consider, among other things, the matters set forth in “Risk Factors” beginning on page PS-7 of this document, page S-1 of the prospectus supplement and page S-1 of the Equity Index Underlying Supplement, as the Notes involve risks not associated with conventional debt securities. We urge you to consult your investment, legal, tax, accounting and other advisors before you invest in the Notes. As used herein, references to the “Issuer”, “HSBC”, “we”, “us” and “our” are to HSBC USA Inc.

HSBC has filed a registration statement (including a prospectus, prospectus supplement and Equity Index Underlying Supplement) with the SEC for the offering to which this document relates. Before you invest, you should read the prospectus, prospectus supplement and Equity Index Underlying Supplement in that registration statement and other documents HSBC has filed with the SEC for more complete information about HSBC and this offering. You may get these documents for free by visiting EDGAR on the SEC’s web site at www.sec.gov. Alternatively, HSBC Securities (USA) Inc. or any dealer participating in this offering will arrange to send you the prospectus, prospectus supplement and Equity Index Underlying Supplement if you request them by calling toll-free 1-866-811-8049.

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 is greater than zero, you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount, equal to the lesser of:

(a) $1,000 + ($1,000 × Reference Return × Upside Participation Rate); and

(b) $1,000 + ($1,000 × Maximum Cap).

If the Reference Return is less than or equal to zero but greater than or equal to the Buffer Level, you will receive $1,000 per $1,000 Principal Amount (zero return).

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

$1,000 + [$1,000 × (Reference Return + 10%)].

Under these circumstances, you will lose 1% of the Principal Amount of your Notes for each percentage point that the Reference Return is below the Buffer Level. For example, if the Reference Return is -30%, you will suffer a 20% loss and receive 80% of the Principal Amount, subject to the credit risk of HSBC. You should be aware that if the Reference Return is less than the Buffer Level, you will lose some or a significant portion (up to 90%) of your investment.

PS-3

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 Sponsor

S&P Dow Jones Indices LLC, a division of S&P Global, is the reference sponsor.

INVESTOR SUITABILITY

The Notes may be suitable for you if:

► You seek an investment with an enhanced return linked to the potential positive performance of the Reference Asset and you believe the level of the Reference Asset will increase over the term of the Notes.

► You are willing to invest in the Notes based on the Maximum Cap of 14.50%, which may limit your return at maturity.

► You are willing to make an investment that is exposed to the negative Reference Return on a 1-to-1 basis for each percentage point that the Reference Return is below the Buffer Level of -10%.

► You are unwilling to invest in the Notes based on the Maximum Cap of 14.50%, which may limit your return at maturity.

► You are unwilling to make an investment that is exposed to the negative Reference Return on a 1-to-1 basis for each percentage point that the Reference Return is below the Buffer Level of -10%.

► You seek an investment that provides full return of principal.

► You are not willing or are unable to assume the credit risk associated with HSBC, as Issuer of the Notes.

PS-4

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. Investing in the Notes is not equivalent to investing directly in any of the stocks included in the Reference Asset. 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 Equity Index Underlying Supplement.

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

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

4 “— 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 Level from the Initial Level beyond the Buffer Level of -10%. Accordingly, if the Reference Return is less than the Buffer Level of -10%, your Payment at Maturity will be less than the Principal Amount of your Notes. You will lose some or a significant portion (up to 90%) of your investment at maturity if the Reference Return is less than the Buffer Level.

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

You will not participate in any appreciation in the level of the Reference Asset (as multiplied by the Upside Participation Rate) beyond the Maximum Cap. You will not receive a return on the Notes greater than the Maximum Cap.

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

The Final Level will be based on the Official Closing Level of the Reference Asset on the Final Valuation Date, subject to postponement for non-trading days and certain market disruption events. Even if the level of the 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 level that is less than the Initial Level, 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 level of the Reference Asset prior to such decrease. Although the actual level of the Reference Asset on the Maturity Date or at other times during the term of the Notes may be higher than the Final Level, the Payment at Maturity will be based solely on the Official Closing Level of the Reference Asset on the Final Valuation Date.

Use of proceeds.

We and/or our affiliates will exercise our judgment and sole discretion in determining the businesses and projects within the Eligible Sectors (as defined below) that will be financed by the proceeds of the Notes. If the use of the proceeds of the Notes is a factor in your decision to invest in the Notes, you should consider our discussion in “Use of Proceeds” and consult with your counsel or other advisors before making an investment in the Notes. There can be no assurance that any of the businesses and projects funded with the proceeds from the Notes will meet our sustainable development goals or your expectations. Furthermore, there is no contractual obligation to allocate the proceeds of the Notes or an amount equal thereto to finance eligible businesses and projects or to provide annual progress reports as described in “Use of Proceeds”. Our or our affiliates’ failure to so allocate, the failure of HSBC Holdings plc to report as further described in “Use of Proceeds”, the failure of any of the businesses and projects funded with the proceeds from the Notes to meet the Framework (as defined herein) or the failure of Sustainalytics or any external assurance provider to opine on the progress report’s conformity with the Framework may affect the value of the Notes and/or have adverse consequences for certain depositors with portfolio mandates to invest in the businesses and projects within the Eligible Sectors (as defined below).

Furthermore, it should be noted that there is currently no clearly-defined definition (legal, regulatory or otherwise) of, nor market consensus as to what constitutes, a “green” or an equivalently-labelled project or as to what precise attributes are required for a particular project to be defined as “green” or “sustainable” or such other equivalent label, nor can any assurance be given that such a clear definition or consensus will develop over time. Accordingly, no assurance is or can be given to depositors that any projects or uses that are the subject of, or related to, any of the businesses and projects funded with the proceeds from the Notes will meet any or all depositors expectations regarding such “green” or other equivalently-labelled performance objectives or that any adverse environmental and/or other impacts will not occur during the implementation of any projects or uses that are the subject of, or related to, any of the businesses and projects funded with the proceeds from the Notes.

The Notes will not bear interest.

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

PS-5

Risks Relating to the Reference Asset

Changes that affect the Reference Asset will affect the market value of the Notes and the amount you will receive at maturity.

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

We make no representation or assurance that the composition of the Reference Asset 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 Reference Asset. If the environmental and social impact of the companies included in the Reference Asset is a factor in an investor’s decision to invest in Notes linked to such Reference Asset, investors should consult with their legal or other advisers before making an investment in the Notes.

The Reference Asset may not be successful and may underperform alternative investment strategies.

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

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

As described in “Description of the Reference Asset,” the Reference Asset 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 Reference Asset. These determinations are also based on information provided by third-parties and scoring methodologies developed by the sponsor and third-parties. The Reference Asset methodology and the underlying score methodologies and may differ substantially from alternative strategies with similar objectives. Decisions to include or exclude components of the Reference Asset will be made solely by the sponsor, and such decisions will affect the performance of the Reference Asset on an ongoing basis. Additionally, the sponsor will make decisions regarding the stocks included in the Reference Asset 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 Reference Asset or any underlying data, scores or methodologies. The Reference Asset may include components that differ significantly from alternative investments strategies with similar objectives and may underperform such alternative investment strategies, perhaps significantly.

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

The Reference Asset was established on January 28, 2019 and therefore has a limited operating history. Because the Reference Asset 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 Reference Asset. 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.

General Risk Factors

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

PS-6

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 Payment at Maturity of the Notes.

The Estimated Initial Value of the Notes, which was determined by us on the Trade Date, is 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 was calculated by us on the Trade Date and is less than the price to public. The Estimated Initial Value reflects 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 determined 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 level 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.

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.

PS-7

USE OF PROCEEDS

An amount equal to the net proceeds of the Notes will be used by the Issuer and/or its affiliates to finance, in whole or in part, new and/or existing businesses and projects in the Eligible Sectors (as defined below) in accordance with the Sustainable Development Goal Framework dated November 2017 (the “Framework”) (as described below) adopted by our indirect parent, HSBC Holdings plc (“HSBC plc”), which HSBC plc furnished under cover of Form 6-K to the SEC on November 14, 2017 and which HSBC plc has made available on their website. You can find the Framework on the HSBC plc’s website under “Green and sustainability bonds — HSBC’s Green Bond Framework”. Nothing in the HSBC plc’s website is incorporated into, or made a part of, this document. We expect HSBC plc to furnish any future versions of the Framework with the SEC under cover of Form 6-K, as well as to make it available on their website.

The term of funding to any eligible business or project under the Framework may be shorter or longer than the term of the Notes and may mature or be sold before or after the Maturity Date of the Notes. In the case of any investment that matures or is sold before the Maturity Date of the Notes, we expect to reallocate funds with respect to that eligible business or project back to our account either until maturity of the Notes or allocation of such amounts to new eligible businesses or projects. If funding for any eligible business or project remains outstanding after the Maturity Date of the Notes, neither we nor any of our consolidated subsidiaries will be required to terminate the financing of such project on the Maturity Date of the Notes.

Payment of principal and interest on the Notes will be made from our general funds and will not be directly linked to the performance of any eligible business or project.

The disclosure in this section regarding the use of proceeds of the Notes supersedes the disclosure about the use of proceeds in the accompanying prospectus supplement and prospectus, to the extent this disclosure is inconsistent with the disclosure in those underlying documents.

Framework

Since HSBC plc’s adoption in 2003 of the Equator Principles, establishing an environmental risk management framework for banks, HSBC plc has been at the forefront in supporting growth and innovation in the market for sustainable finance. HSBC plc was one of the first banks to support the International Capital Market Association’s Green Bond Principles in 2014, working with others to establish clear and consistent rules for green investing, and HSBC plc also promoted the 17 Sustainable Development Goals formally established by United Nations General Assembly in September 2015, which implemented a common framework for public and private stakeholders to set their agendas and define their policies and strategies over the following 15 years (the “SDG”). The Framework was a further step towards contributing capital towards the accomplishment of the SDG.

HSBC plc believes that the Framework remains consistent with the current International Capital Market Association’s Green Bond Principles, Social Bond Principles and Sustainability Bond Guidelines and in reaching such conclusion, HSBC plc relied in part on a second party opinion dated 6 November 2017 from Sustainalytics, an external assurance provider, confirming the alignment of the Framework with the International Capital Market Association’s 2017 Sustainability Bond Guidelines. That opinion is available on HSBC plc’s website.

Eligible Sectors

In accordance with the Framework, the “Eligible Sectors” comprise:

Good Health and Well-being (SDG 3)—activities that strengthen the capacity of all countries, in particular developing countries, for provision of free or subsidized healthcare, and early warning, risk reduction and management of health crises.

Quality Education (SDG 4)—activities that (i) expand access to primary, secondary, adult and vocational education, (ii) target women and minority inclusion in education or (iii) improve educational infrastructure.

Clean Water and Sanitation (SDG 6)—activities that (i) expand public access to safe and affordable drinking water, (ii) provide access to adequate sanitation facilities, (iii) improve water quality or (iv) increase water-use efficiency through water recycling, treatment and reuse (including treatment of wastewater).

Affordable and Clean Energy (SDG 7)—activities that involve (i) generation of energy from renewable sources, (ii) construction, maintenance and/or expansion of associated distribution networks, (iii) manufacturing of components of renewable energy technology, (iv) development of products or technology and their implementation that reduces energy consumption of underlying asset, technology, product or system(s), (v) improved efficiency in the delivery of bulk energy services or (vi) manufacturing of components to enable energy efficiency.

Eligibility Criteria of Businesses and Projects

The net proceeds will be used to finance, in whole or in part, future and/or re-finance existing businesses and projects, including our own operations, that promote any of the Eligible Sectors in accordance with the Framework.

We will determine the eligibility of businesses and projects based on whether they apply their funds to Eligible Sectors and whether a significant net positive sustainability impact is achieved by them. If a business or project derives at least 90% its revenue from activities within the Eligible Sectors, it would be considered for financing with the net proceeds. In these instances, the net proceeds can be used for general purposes, so long as this financing does not fund expansion into activities falling outside of the Eligible Sectors.

There is no contractual obligation to allocate the proceeds of the Notes or an amount equal thereto to finance eligible businesses and projects or to provide annual progress reports as further described below. Our failure to so allocate, the failure of HSBC plc to report, the failure of any of the businesses and projects funded with the proceeds from the Notes to meet the Framework or the failure of Sustainalytics or any external assurance provider to opine on the progress report’s conformity with the Framework will not constitute an Event of Default with respect to the Notes and may affect the value of the Notes and/or have adverse consequences for certain investors with portfolio mandates to invest in green assets.

We recognize that businesses and projects may benefit the environment in important ways while also degrading it in others. Accordingly, our assessment of environmental and societal benefits will consider the balance of impact in determining the overall net benefit. We will exercise our professional judgment, discretion and sustainability knowledge in determining eligibility of businesses and projects for the use of the net proceeds.

Businesses and projects that are involved in the following operations will be ineligible: (i) nuclear power generation; (ii) weapons; (iii) alcohol; (iv) gambling / adult entertainment; and (v) palm oil. Moreover, the businesses and projects will not include any coal-fired power plants, the extraction and refining of coal, thermal coal mines or mountaintop removal.

Management and Tracking of the Proceeds

HSBC plc’s Green Bond Committee has responsibility for governing the Framework and for the ratification of eligible businesses and projects by applying the guidelines in the Framework. The Green Bond Committee also will track the use of proceeds of the Notes using its internal information system, as described in the Framework. If any portion of the net proceeds has not been applied to Eligible Sectors, we may invest such unused proceeds according to our local liquidity management guidelines.

Reporting

HSBC plc expects to provide a progress report on an annual basis until all proceeds have been fully allocated including:

► aggregate amounts of funds allocated to each of the Eligible Sectors, together with a description of the types of business and projects financed;

► the remaining balance of unallocated net proceeds at the reporting period end; and

► confirmation that the use of proceeds of the Notes issued conforms with the Framework.

Moreover, Sustainalytics will act as the external assurance provider that will independently review the progress report, on an annual basis, and opine on its conformity with the Framework. We expect HSBC plc to make the annual progress reports and related opinions available on its website.

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 level of the Reference Asset relative to its Initial Level. We cannot predict the Final Level. The assumptions we have made in connection with the illustrations set forth below may not reflect actual events, and the hypothetical Initial Level used in the table and examples below is not expected to be the actual Initial Level of the Reference Asset. You should not take this illustration or these examples as an indication or assurance of the expected performance of the Reference Asset 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 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:

►	Principal Amount:	$1,000
►	Hypothetical Initial Level*:	1,000
►	Upside Participation Rate:	150%
►	Maximum Cap:	14.50%
►	Buffer Level:	-10%

*The actual Initial Level is set forth on page PS-2 of this pricing supplement.

Hypothetical Final Level	Hypothetical Reference Return	Hypothetical Final Settlement Value	Hypothetical Return on the Notes
2,000.00	100.000%	$1,145.00	14.50%
1,800.00	80.000%	$1,145.00	14.50%

PS-10

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 level of the Reference Asset increases from the Initial Level of 1,000.00 to a Final Level of 1,050.00.

Reference Return:	5.00%
Final Settlement Value:	$1,075.00

Because the Reference Return is positive, and the Reference Return multiplied by the Upside Participation Rate is less than the Maximum Cap, the Final Settlement Value would be $1,075.00 per $1,000 Principal Amount, calculated as follows:

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

= $1,000 + ($1,000 × 5.00% × 150%)

= $1,075.00

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 Maximum Cap.

Example 2: The level of the Reference Asset increases from the Initial Level of 1,000.00 to a Final Level of 1,300.00.

Reference Return:	30.00%
Final Settlement Value:	$1,145.00

Because the Reference Return is positive, and the Reference Return multiplied by the Upside Participation Rate is greater than the Maximum Cap, the Final Settlement Value would be $1,145.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + ($1,000 × Maximum Cap)

= $1,000 + ($1,000 × 14.50%)

= $1,145.00

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

Example 3: The level of the Reference Asset decreases from the Initial Level of 1,000.00 to a Final Level of 920.00.

Reference Return:	-8.00%
Final Settlement Value:	$1,000.00

Because the Reference Return is less than zero but greater than the Buffer Level of -10%, the Final Settlement Value would be $1,000.00 per $1,000 Principal Amount (a zero return).

Example 4: The level of the Reference Asset decreases from the Initial Level of 1,000.00 to a Final Level of 700.00.

Reference Return:	-30.00%
Final Settlement Value:	$800.00

Because the Reference Return is less than the Buffer Level of -10%, the Final Settlement Value would be $800.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + [$1,000 × (Reference Return + 10%)]

= $1,000 + [$1,000 × (-30.00% + 10%)]

= $800.00

Example 4 shows that you are exposed on a 1-to-1 basis to declines in the level of the Reference Asset beyond the Buffer Level of -10%. You will lose some or a significant portion (up to 90%) of your investment.

DESCRIPTION OF THE 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.

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 Index from September 26, 2013 through January 27, 2019 and the historical performance of the Index from January 28, 2019 to September 26, 2023. The Index has been calculated by S&P Dow Jones Indices LLC only since January 28, 2019. The hypothetical back-tested performance of the Index set forth in the graph below was calculated using the selection criteria and methodology employed to calculate the Index since its inception on January 28, 2019. The black vertical line shows the inception on January 28, 2019.

Hypothetical and Historical Comparative Data

The hypothetical back-tested Index data only reflects the application of that methodology in hindsight, since the Index was not actually calculated and published prior to January 28, 2019. The hypothetical back-tested Index 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 Index data, all of which can affect actual performance. Consequently, you should not rely on that data as a reflection of what the actual Index performance would have been had the Index been in existence or in forecasting future Index performance. The graph above also reflects the actual Index performance from January 28, 2019 to September 26, 2023 based on information that we obtained from Bloomberg L.P. Any hypothetical or actual historical upward or downward trend in the level of the Index during any period shown is not an indication that the level of the Index is more or less likely to increase or decrease at any time during the term of the Notes.

PS-12

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 in “Payment at Maturity” in this document.  In that 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.

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 set forth on the cover page of this pricing supplement, for distribution to other registered broker-dealers, or will offer the Notes directly to investors.  HSBC Securities (USA) Inc. has offered 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 an underwriting discount up to 1.50% and referral fees of up to 0.60% 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 2.10% per $1,000 Principal Amount.

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 this pricing supplement 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.

Delivery of the Notes will be made against payment for the Notes on 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.

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

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 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 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 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 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 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 Reference Asset is or becomes a PFIC or a USRPHC.

PS-13

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 the 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 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.

VALIDITY OF THE NOTES

In the opinion of Mayer Brown LLP, as counsel to the Issuer, when this pricing supplement has been attached to, and duly notated on, the master note that represents the Notes pursuant to the Senior Indenture referred to in the prospectus supplement dated February 23, 2021, and issued and paid for as contemplated herein, the Notes offered by this pricing supplement will be valid, binding and enforceable obligations of the Issuer, entitled to the benefits of the Senior Indenture, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability (including, without limitation, concepts of good faith, fair dealing and the lack of bad faith). This opinion is given as of the date hereof and is limited to the laws of the State of New York, the Maryland General Corporation Law (including the statutory provisions, all applicable provisions of the Maryland Constitution and the reported judicial decisions interpreting the foregoing) and the federal laws of the United States of America. This opinion is subject to customary assumptions about the trustee’s authorization, execution and delivery of the Senior Indenture and the genuineness of signatures and to such counsel’s reliance on the Issuer and other sources as to certain factual matters, all as stated in the legal opinion dated February 23, 2021, which has been filed as Exhibit 5.3 to the Issuer’s registration statement on Form S-3 dated February 23, 2021.
