**PAYMENT ON THE NOTES**

**Call Feature**

The Notes may be called at our option, in whole, but not in part, on each Call Payment Date. In order to call the Notes, we or the calculation agent will distribute written notice to The Depository Trust Company of our intent to call the Notes on or prior to the applicable Call Notice Date. We or the calculation agent will have no independent obligation to notify you directly and you should expect to receive such notifications from your broker. If the Notes are called, you will receive a cash payment, per $1,000 Principal Amount, equal to the Principal Amount plus the applicable Contingent Coupon on the corresponding Call Payment Date

**Contingent Coupon**

We will pay a monthly Contingent Coupon payment on a Coupon Payment Date if the Official Closing Level of each Underlying on the applicable Observation Date is greater than or equal to its Coupon Trigger. Otherwise, no coupon will be paid on such Coupon Payment Date. For information regarding the record dates applicable to the Contingent Coupons payable on the Notes, please see the section entitled "Description of Notes—Interest and Principal Payments—Recipients of Interest Payments" beginning on page S-14 in the accompanying prospectus supplement. The Contingent Coupon Rate will be 10.00% per annum (or $8.333 per $1,000 Principal Amount per monthly period, if payable).

**Payment at Maturity**

Unless the Notes are called prior to maturity, on the Maturity Date and for each $1,000 Principal Amount, you will receive a cash payment equal to the Final Settlement Value determined as follows:

■ **If the Reference Return of the Least Performing Underlying is greater than or equal to -28.00%**:

$1,000 + final Contingent Coupon

■ **If the Reference Return of the Least Performing Underlying is less than -28.00%**:

$1,000 + [$1,000 × (Reference Return of the Least Performing Underlying + 28.00%) × Downside Leverage Factor].

If the Notes are not called and the Final Value of the Least Performing Underlying is less than its Buffer Level, you will receive protection from the first 28.00% of any losses, with 1:1.3889x exposure to each 1% decline that the Reference Return of the Least Performing Underlying is less than -28.00%. You may lose some or all of your investment. Even with any Contingent Coupons received prior to maturity, your return on the Notes may be negative in this case.

**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.

**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 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:

🞂 "—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.**

If the Notes are not called, you will be exposed to the decline in the Final Value of the Least Performing Underlying from its Initial Value beyond the Buffer Level. Accordingly, if the Reference Return of the Least Performing Underlying is less than the Buffer Level, your Payment at maturity will be less than the Principal Amount of your Notes. You will lose some or a significant portion (up to 100.00%) of your investment at maturity if the Reference Return is less than the Buffer Level. Even with any Contingent Coupons received prior to maturity, your return on the Notes may be negative in this case.

**You may not receive any Contingent Coupons.**

We will not necessarily make periodic coupon payments on the Notes. If the Official Closing Level of any Underlying on an Observation Date is less than its Coupon Trigger, we will not pay you the Contingent Coupon applicable to that Observation Date. If on each of the Observation Dates, the Official Closing Level of any Underlying is less than its Coupon Trigger, we will not pay you any Contingent Coupons during the term of, and you will not receive a positive return on, the Notes. Generally, this non-payment of the Contingent Coupon coincides with a period of greater risk of principal loss on the Notes.

**Your return on the Notes is limited to the Principal Amount plus the Contingent Coupons, if any, regardless of any appreciation in the value of any Underlying.**

For each $1,000 Principal Amount, you will receive $1,000 at maturity plus the final Contingent Coupon if the Final Value of the Least Performing Underlying is equal to or greater than its Coupon Trigger, regardless of any appreciation in the value of any Underlying, which may be significant. Accordingly, the return on the Notes may be significantly less than the return on a direct investment in the stocks included in the Underlyings during the term of the Notes.

**Higher Contingent Coupon Rates or lower Buffer Level are generally associated with Underlyings with greater expected volatility and therefore can indicate a greater risk of loss.**

"Volatility" refers to the frequency and magnitude of changes in the value of an Underlying. The greater the expected volatility with respect to an Underlying on the Pricing Date, the higher the expectation as of the Pricing Date that the value of that Underlying could close below its Coupon Trigger on an Observation Date or its Reference Return could be less than the Buffer Level, indicating a higher expected risk of non-payment of Contingent Coupons or loss on the Notes. This greater expected risk will generally be reflected in a higher Contingent Coupon Rate than the yield payable on our conventional debt securities with a similar maturity, or in more favorable terms (such a lower Coupon Trigger or a higher Contingent Coupon Rate) than for similar securities linked to the performance of an Underlying with a lower expected volatility as of the Pricing Date. You should therefore understand that a relatively higher Contingent Coupon Rate may indicate an increased risk of loss. Further, a relatively lower Buffer Level may not necessarily indicate that the Notes have a greater likelihood of a repayment of principal at maturity. The volatility of an Underlying can change significantly over the term of the Notes. The value of an Underlying for your Notes could fall sharply, which could result in a significant loss of principal. You should be willing to accept the downside market risk of the Least Performing Underlying and the potential to lose some or all of your principal at maturity not receive any Contingent Coupons.

**If the Notes are not called, your return will be based on the Reference Return of the Least Performing Underlying.**

If the Notes are not called prior to maturity, your return will be based on the Reference Return of the Least Performing Underlying without regard to the performance of any other Underlying. As a result, you could lose a significant portion of your initial investment if the Final Value of the Least Performing Underlying is less than 72.00% of its Initial Value, even if there is an increase in the value of any other

Underlying. This could be the case even if any other Underlying increased by an amount greater than the decrease in the Least Performing Underlying.

**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 receiving no Contingent Coupons and sustaining a significant loss on your investment than if the Notes were linked to just one Underlying.**

The risk that you will not receive any Contingent Coupons, or 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 one of the Underlyings will close below its respective Coupon Trigger on any Observation Date (including the Final Valuation Date) and its Reference Return will be less than the Buffer Level, than if the Notes were linked to only one Underlying. Therefore, it is more likely that you will not receive any Contingent Coupons, and that you will suffer a significant loss on your investment. In addition, because each Underlying must close above its Call Threshold on a Call Observation Date in order for the Notes to be called, the Notes are less likely to be called than if the Notes were linked to just one Underlying.

**The amount payable on the Notes is not linked to the values of the Underlyings at any time other than the Observation Dates, including the Final Valuation Date.**

The payments on the Notes will be based on the Official Closing Levels of the Underlyings on the Observation Dates, including the Final Valuation Date, subject to postponement for non-trading days and certain Market Disruption Events. Even if the value of each Underlying is greater than or equal to its Coupon Trigger during the term of the Notes other than on an Observation Date but then decreases on an Observation Date to a value that is less than its Coupon Trigger, the Contingent Coupon will not be payable for the relevant monthly period. Similarly, if the Notes are not called, even if the value of the Least Performing Underlying is greater than or equal to 72.00% of its Initial Value during the term of the Notes other than on the Final Valuation Date but then decreases on the Final Valuation Date and its Reference Return is less than the Buffer Level, the Payment at Maturity will be less, possibly 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 values of the Underlyings on the Maturity Date or at other times during the term of the Notes may be higher than their respective values on the Observation Dates, whether each Contingent Coupon will be payable and the Payment at Maturity will be based solely on the Official Closing Levels of the Underlyings on the applicable Observation Dates.

**The Notes may be called prior to the Maturity Date.**

If the Notes are called early, the holding period over which you may receive coupon payments could be as little as approximately 1 year. There is no guarantee that you would be able to reinvest the proceeds from an investment in the Notes at a comparable return for a similar level of risk in the event the Notes are called prior to the Maturity Date.

***Risks Relating to the Reference Asset***

**Changes that affect an Underlying may affect the value of that 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 that Underlying and the manner in which the reference sponsor takes account of certain changes affecting those stocks may affect the value of that Underlying. The policies of the reference sponsor could also affect the value of that 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.

**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.

**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 was determined by us on the Pricing 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 Pricing 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 Pricing 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 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 Pricing 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.

**You will not have any ownership interest in the stocks included in an Underlying.**

As a holder of the Notes, you will not have any ownership interest in the stocks included in an Underlying, 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 an Underlying.

**The Notes lack liquidity.**

The Notes will not be listed on any securities exchange. 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 Official Closing Level of an Underlying on any Observation Date, including the Final Valuation Date. 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 Underlyings or the return on the Notes**.**

The table and examples below illustrate how the Contingent Coupon and the Payment at Maturity would be calculated with respect to a $1,000 investment in the Notes, given a range of hypothetical performances of any Underlying. The hypothetical returns on the Notes below are numbers, expressed as percentages, that result from comparing the Payment at Maturity per $1,000 Principal Amount to $1,000. You should consider carefully whether the Notes are suitable to your investment goals. The numbers appearing in the following table and examples have been rounded for ease of analysis. The following table and examples assume the following:

---

| | |
|:---|:---|
| &nbsp;&nbsp;🞂 Principal Amount: | &nbsp;&nbsp;$1000 |
| &nbsp;&nbsp;🞂 Hypothetical Initial Value | &nbsp;&nbsp;1,000.00\* |
| &nbsp;&nbsp;🞂 Buffer Level: | &nbsp;&nbsp;-28.00% |
| &nbsp;&nbsp;🞂 Downside Leverage Factor: | &nbsp;&nbsp;1/0.72 (approximately 1.3889x) |
| &nbsp;&nbsp;🞂 Hypothetical Coupon Trigger: | &nbsp;&nbsp;720.00 (72.00% of the Initial Value) |
| &nbsp;&nbsp;🞂 Hypothetical Contingent Coupon Rate: | &nbsp;&nbsp;10.00% per annum (approximately 0.8333% for each month in which it is payable). If the Official Closing Level of each Underlying on *every* Observation Date is greater than or equal to its Coupon Trigger, the Contingent Coupon paid over the term of the Notes would total $300.00 per $1,000 Principal Amount of the Notes. |

---

\* 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 is set forth on page PS-3 of this document.

**Example 1**—**The Notes are called after the first Call Notice Date and each Underlying closed at or above its Coupon Trigger on each Observation Date prior to the Notes being called.**

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;**<u>Underlying</u>** | &nbsp;&nbsp;**<u>Initial Value</u>** | &nbsp;&nbsp;**<u>Official Closing Level</u>** |
| &nbsp;&nbsp;RTY | &nbsp;&nbsp;1000.00 | &nbsp;&nbsp;1,200.00 (120.00% of Initial Value) |
| &nbsp;&nbsp;NDX | &nbsp;&nbsp;1000.00 | &nbsp;&nbsp;1,290.00 (129.00% of Initial Value) |

---

---

| | |
|:---|:---|
| &nbsp;&nbsp;**Payment Upon a Call:** | &nbsp;&nbsp;**$1008.333** |

---

Because the Notes are called and the Official Closing Value of each Underlying on the twelfth Coupon Observation Date is at or above its Coupon Trigger, you will receive $1,008.333 per Note, reflecting the Principal Amount plus the Contingent Coupon. When added to the Contingent Coupon payment of $91.663 received prior to the first Call Notice Date, we will have paid you a total of $1,100.00 per Note, resulting in a 10.00% return on the Notes. No extra payment will be made on account of each Underlying closing above its respective Initial Value.

**Example 2**— **The Notes are not called, the Final Value of the Least Performing Underlying is greater than or equal to 72.00% of its Initial Value, and each Underlying closed at or above its Coupon Trigger on the first three Observation Dates prior to the Final Valuation Date.**

---

| &nbsp;&nbsp;RTY | &nbsp;&nbsp;1000.00 | &nbsp;&nbsp;950.00 (95.00% of Initial Value) |
| &nbsp;&nbsp;NDX | &nbsp;&nbsp;1000.00 | &nbsp;&nbsp;869.50 (86.95% of Initial Value) |

---

NDX is the Least Performing Underlying.

---

| | |
|:---|:---|
| &nbsp;&nbsp;Reference Return of the Least Performing Underlying: | &nbsp;&nbsp;-13.05% |
| &nbsp;&nbsp;**Payment at Maturity:** | &nbsp;&nbsp;**$1008.333** |

---

Because the Final Value of the Least Performing Underlying is greater than or equal to its Coupon Trigger, you will receive $1,008.333 per Note, reflecting the Principal Amount plus the final Contingent Coupon.

When added to the Contingent Coupon payments of $100.00 received in prior to maturity, we will have paid you a total of $1,108.333 per Note, resulting in a 10.8333% return on the Notes.

**Example 3**—**The Notes are not called, the Final Value of the Least Performing Underlying is less than 72.00% of its Initial Value, and the Underlyings did not all close at or above their respective Coupon Triggers on any of the Observation Dates prior to maturity.**

---

|:---|:---|:---|
| &nbsp;&nbsp;**<u>Underlying</u>** | &nbsp;&nbsp;**<u>Initial Value</u>** | &nbsp;&nbsp;**<u>Final Value</u>** |
| &nbsp;&nbsp;RTY | &nbsp;&nbsp;1000.00 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 600.00 (60.00% of Initial Value) |
| &nbsp;&nbsp;NDX | &nbsp;&nbsp;1000.00 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 500.00 (50.00% of Initial Value) |

---

NDX is the Least Performing Underlying.

---

| | |
|:---|:---|
| &nbsp;&nbsp;Reference Return of the Least Performing Underlying: | &nbsp;&nbsp;-50.00% |
| &nbsp;&nbsp;**Payment at Maturity:** | &nbsp;&nbsp;**$694.442** |

---

Because the Reference Return of the Least Performing Underlying is less than the Buffer Level, you will receive $694.442 per $1,000 Principal Amount, calculated as follows:

Final Settlement Value = $1,000 + [$1,000 x (-50.00% + 28.00%) x 1.3889] = $694.442

Because there was no Contingent Coupon payable in respect of the prior Observation Dates, we will pay you a total of $694.442, resulting in a<br> -30.5558% return on the Notes.

If the Notes are not called and the Reference Return of the Least Performing Underlying is less than the Buffer Level, you will be exposed on an approximately 1:1.3889 basis to any decrease in the value of the Least Performing Underlying beyond the Buffer Level. **You will lose some or all of your investment.**

**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 of an Underlying, 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 an Underlying on that scheduled trading day, then the accelerated Final Valuation Date for that Underlying 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 following the postponed accelerated Final Valuation Date. 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 Final Value 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 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 underwriting discounts of up to 0.10% 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 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.

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 contingent income-bearing 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 contingent income-bearing pre-paid executory contract with respect to the Underlyings. Because there are no statutory provisions, regulations, published rulings or judicial decisions addressing the characterization for U.S. federal income tax purposes of securities with terms that are substantially the same as those of the Notes, other characterizations and treatments are possible and the timing and character of income in respect of the Notes might differ from the treatment described herein. For example, the Notes could be treated as debt instruments that are "contingent payment debt instruments" for U.S. federal income tax purposes subject to the treatment described under the heading "U.S. Federal Income Tax Considerations — Tax Treatment of U.S. Holders — U.S. Federal Income Tax Treatment of the Notes as Indebtedness for U.S. Federal Income Tax Purposes — Contingent Notes" in the accompanying prospectus supplement.

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

*U.S. Holders.* Please see the discussion under the heading "U.S. Federal Income Tax Considerations — Tax Treatment of U.S. Holders — Certain Notes Treated as a Put Option and a Deposit or an Executory Contract — Certain Notes Treated as Executory Contracts" in the accompanying prospectus supplement for further discussion of U.S. federal income tax considerations applicable to U.S. holders (as defined in the accompanying prospectus supplement). Pursuant to the approach discussed above, we intend to treat any gain or loss upon maturity or an earlier sale, exchange, or call as capital gain or loss in an amount equal to the difference between the amount you receive at such time (other than with respect to a Contingent Coupon) and your tax basis in the Note. Any such gain or loss will be long-term capital gain or loss if you have held the Note for more than one year at such time for U.S. federal income tax purposes. Your tax basis in a Note generally will equal your cost of the Note. In addition, the tax treatment of the Contingent Coupons is unclear. Although the tax treatment of the Contingent Coupons is unclear, we intend to treat any Contingent Coupon, including on the Maturity Date, as ordinary income includible in income by you at the time it accrues or is received in accordance with your normal method of accounting for U.S. federal income tax purposes.

*Non-U.S. Holders.* Please see the discussion under the heading "U.S. Federal Income Tax Considerations — Tax Treatment of Non-U.S. Holders" in the accompanying prospectus supplement for further discussion of U.S. federal income tax considerations applicable to non-U.S. holders (as defined in the accompanying prospectus supplement). Because the U.S. federal income tax treatment (including the applicability of withholding) of the Contingent Coupons is uncertain, the entire amount of the Contingent Coupons will be subject to U.S. federal income tax withholding at a 30% rate (or at a lower rate under an applicable income tax treaty). We will not pay any additional amounts in respect of such withholding.

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 Underlyings 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 Underlyings 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**

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.
