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 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 ETF 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 ETF 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-5 of this document, page S-1 of the prospectus supplement and page S-1 of the ETF 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 ETF Underlying Supplement) with the SEC for the offering to which this document relates. Before you invest, you should read the prospectus, prospectus supplement and ETF 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.

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:

(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 Barrier Percentage, you will receive $1,000 per $1,000 Principal Amount (zero return).

If the Reference Return is less than the Barrier Percentage, you will lose some or all of your investment.

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

INVESTOR SUITABILITY

The Notes may be suitable for you if:

The Notes may not be suitable for you if:

4 You seek an investment with an enhanced return linked to the potential positive performance of the Reference Asset and you believe the price of the Reference Asset will increase over the term of the Notes. 4You are willing to invest in the Notes based on the Maximum Cap of 167.00%, which may limit your return at maturity. The actual Maximum Cap will be determined on the Pricing Date. 4You are willing to make an investment that is exposed to the negative Reference Return on a 1-to-1 basis for each percentage point decline in the Reference Asset if the Reference Return is less than -30%. 4You are willing to forgo dividends or other distributions paid to holders of the Reference Asset, or the stocks held by the Reference Asset or included in the Underlying Index. 4You are willing to accept the risk and return profile of the Notes versus a conventional debt security with a comparable maturity issued by HSBC or another issuer with a similar credit rating. 4You do not seek current income from your investment. 4You do not seek an investment for which there is an active secondary market. 4You are willing to hold the Notes to maturity. 4You are comfortable with the creditworthiness of 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 on page S-1 of the accompanying ETF Underlying Supplement. Investing in the Notes is not equivalent to investing directly in the Reference Asset or any of the stocks included in the Underlying Index. 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 ETF Underlying Supplement.

In addition to the risks discussed below, you should review “Risk Factors” in the accompanying prospectus supplement and ETF 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;

4“— General Risks Related to Index Funds” in the ETF Underlying Supplement

4“— Securities Prices Generally are Subject to Political, Economic, Financial, and Social Factors that Apply to the Markets in which They Trade and, to a Lesser Extent, Foreign Markets” in the ETF Underlying Supplement; and

4“— Time Differences Between the Domestic and Foreign Markets and New York City may Create Discrepancies in the Trading Level or Price of the Notes” in the ETF 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 fully exposed to the decline in the Reference Asset if the Reference Return is less than the Barrier Percentage of -30.00%. Accordingly, if the Reference Return is less than the Barrier Percentage, your Payment at Maturity will be less than the Principal Amount of your securities by an amount proportionate to the decrease in the Reference Asset from its Initial Value. There is no minimum payment on the securities and, accordingly, you could lose your entire investment.

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

You will not participate in any appreciation in the price of the Reference Asset (as multiplied by the Upside Participation Rate) beyond the Maximum Cap of 167.00%. 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 price of the Reference Asset at any time other than on the Final Valuation Date.

The Final Value will be based on the Official Closing Price of the Reference Asset on the Final Valuation Date, subject to postponement for non-trading days and certain market disruption events. Even if the price 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 price 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 price of the Reference Asset prior to such decrease. Although the actual price of the 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 Price of the Reference Asset on the Final Valuation Date.

Risks Relating to the Reference Asset

There are risks associated with concentration of investment in a particular sector.

The equity securities held by the ICLN are issued by companies whose primary line of business is directly associated with the clean energy sector. Consequently, the value of the notes may be subject to greater volatility and be more adversely affected by a single economic, environmental, political or regulatory occurrence affecting such industries than an investment linked to a more broadly diversified group of issuers. Clean energy companies may be highly dependent upon government subsidies, contracts with government entities and the successful development of new and proprietary technologies. In addition, seasonal weather conditions, fluctuations in the supply of and demand for clean energy products, changes in energy prices and international political events may cause fluctuations in the performance of clean energy companies and the prices of their securities.

The price of the ICLN is subject to currency exchange risk.

Because the price of the ICLN is related to the U.S. dollar value of stocks included in the Underlying Index, holders of the notes will be exposed to currency exchange rate risk with respect to each of the currencies in which such component securities trade. Exchange rate movements for a particular currency are volatile and are the result of numerous factors including the supply of, and the demand for, that currency, as well as relevant government policy, intervention or actions, but are also influenced significantly from time to time by political or economic developments, and by macroeconomic factors and speculative actions related to the relevant region. An investor’s net exposure will depend on the extent to which the applicable currencies strengthen or weaken against the U.S. dollar. If the dollar strengthens against the applicable currencies, the price of the ICLN may be adversely affected and the payment at maturity on the notes may be reduced. Of particular importance to potential currency exchange risk are:

PS-5

• existing and expected rates of inflation;

• existing and expected interest rate levels;

• the balance of payments; and

• the extent of governmental surpluses or deficits in the applicable countries.

All of these factors are in turn sensitive to the monetary, fiscal and trade policies pursued by the governments of the applicable countries and other countries important to international trade and finance. The amount we pay in respect of the notes on the maturity date, if any, will be determined solely in accordance with the procedures described in this document.

Changes that affect the Reference Asset or the Underlying Index may affect the price of the Reference Asset and the market value of the Notes and the amount you will receive at maturity.

The policies of the reference issuer or iShares Trust (the “Index Sponsor”), the index sponsor of the Underlying Index, concerning additions, deletions and substitutions of the stocks held by the Reference Asset or included in the Underlying Index, as applicable, and the manner in which the reference issuer or the Index Sponsor takes account of certain changes affecting those stocks may affect the price of the Reference Asset. The policies of the reference issuer or the Index Sponsor with respect to the calculation of the Reference Asset or the Underlying Index, as applicable, could also affect the price of the Reference Asset. The reference issuer or the Index Sponsor may discontinue or suspend calculation or dissemination of the Reference Asset or the Underlying Index, as applicable. Any such actions could affect the price of the Reference Asset and the value of the Notes.

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 will not bear interest.

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

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 Payment at Maturity of the Notes.

Owning the Notes is not the same as owning the Reference Asset or the stocks included in the Underlying Index.

The return on your Notes may not reflect the return you would realize if you actually owned the Reference Asset or stocks included in the Underlying Index. As a holder of the Notes, you will not have voting rights or rights to receive dividends or other distributions or other rights as would the holders of the Reference Asset or the stocks included in the Underlying Index.

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 Payment at Maturity of the Notes.

The price of your Notes in the secondary market, if any, 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 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 price 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.

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

PS-6

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 Notes lack liquidity.

The Notes will not be listed on any securities exchange or automated quotation system. HSBC Securities (USA) Inc. is not required to offer to purchase the Notes in the secondary market, if any exists. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Notes easily. Because other dealers are not likely to make a secondary market for the Notes, the price at which you may be able to trade your Notes is likely to depend on the price, if any, at which HSBC Securities (USA) Inc. is willing to buy the Notes.

Potential conflicts of interest may exist.

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

Uncertain tax treatment.

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

ILLUSTRATIVE EXAMPLES

The following table and examples are provided for illustrative purposes only and are hypothetical. They do not purport to be representative of every possible scenario concerning increases or decreases in the price of the Reference Asset relative to its Initial Value. We cannot predict the Final Value. 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 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 are based on the following terms:

4	Principal Amount:	$1,000
4	Hypothetical Initial Value:	$100.00
4	Upside Participation Rate:	200%
4	Maximum Cap:	167.00%
4	Barrier Percentage:	-30.00%

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

PS-8

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 price of the Reference Asset increases from the Initial Value of $100.00 to a Final Value of $105.00.

Reference Return:	5.00%
Final Settlement Value:	$1,100.00

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 $1,100.00 per $1,000 Principal Amount, calculated as follows:

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

= $1,000 + ($1,000 × 5.00% ×200%)

= $1,100.00

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 price of the Reference Asset increases from the Initial Value of $100.00 to a Final Value of $190.00.

Reference Return:	90.00%
Final Settlement Value:	$2,670.00

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 $2,670.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + ($1,000 × Maximum Cap)

= $1,000 + ($1,000 × 167.00%)

= $2,670.00

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 price of the Reference Asset decreases from the Initial Value of $100.00 to a Final Value of $95.00.

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

Because the Reference Return is less than zero but greater than the Barrier Percentage of -30.00%, the Final Settlement Value would be $1,000.00 per $1,000 Principal Amount (a zero return).

Example 4: The price of the Reference Asset decreases from the Initial Value of $100.00 to a Final Value of $50.00

Reference Return:	-50.00%
Final Settlement Value:	$500.00

Because the Reference Return is less than the Barrier Percentage of -30.00%, the Final Settlement Value would be $500.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + ($1,000 × (Reference Return)

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 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 varying underwriting discounts of up to 0.75% and referral fees of up to 1.60% 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 1.60% 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.

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

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.

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, and subject to the discussion below regarding “constructive ownership transactions”, we do not intend to report any income or gain with respect to the Notes prior to their maturity or an earlier sale or exchange and we intend to treat any gain or loss upon maturity or an earlier sale or exchange as long-term capital gain or loss, provided that you have held the Note for more than one year at such time for U.S. federal income tax purposes.

Despite the foregoing, U.S. holders (as defined under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement) should be aware that the Internal Revenue Code of 1986, as amended (the “Code”), contains a provision, Section 1260 of the Code, which sets forth rules which are applicable to what it refers to as “constructive ownership transactions.” Due to the manner in which it is drafted, the precise applicability of Section 1260 of the Code to any particular transaction is often uncertain. In general, a “constructive ownership transaction” includes a contract under which an investor will receive payment equal to or credit for the future value of any equity interest in a regulated investment company (such as shares of the Reference Asset (the “Underlying Shares”)). Under the “constructive ownership” rules, if an investment in the Notes is treated as a “constructive ownership transaction,” any long-term capital gain recognized by a U.S. holder in respect of a Note will be recharacterized as ordinary income to the extent such gain

PS-11

exceeds the amount of “net underlying long-term capital gain” (as defined in Section 1260 of the Code) (the “Excess Gain”). In addition, an interest charge will also apply to any deemed underpayment of tax in respect of any Excess Gain to the extent such gain would have resulted in gross income inclusion for the U.S. holder in taxable years prior to the taxable year of the sale, exchange or maturity of the Note (assuming such income accrued at a constant rate equal to the applicable federal rate as of the date of sale, exchange or maturity of the Note). Furthermore, unless otherwise established by clear and convincing evidence, the “net underlying long-term capital gain” is treated as zero.

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

We will not attempt to ascertain whether the Reference Asset or any of the entities whose stock is owned by 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 the Reference Asset or one or more of the entities whose stock is owned by 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 Reference Asset or the entities whose stock is owned by the Reference Asset and consult your tax advisor regarding the possible consequences to you if the Reference Asset or one or more of the entities whose stock is owned by the 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 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.
