If the Official Closing Level of the Reference Asset is at or above the Call Threshold on any Observation Date the Notes will be automatically called, and you will receive a cash payment, per $1,000 Principal Amount, equal to the Principal Amount plus the applicable Coupon on the corresponding Call Payment Date.

Coupon

Unless the Notes are automatically called, we will pay a semi-annual Coupon payment on each Coupon Payment Date. For information regarding the record dates applicable to the 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-17 in the accompanying prospectus supplement. The Coupon Rate will be 8.00% per annum (or $40.00 per $1,000 Principal Amount per semi-annual period).

FWP-8 

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

The Notes do not guarantee any return of principal and you may lose all of your Principal Amount.

The Notes do not guarantee any return of principal. The Notes differ from ordinary debt securities in that we will not pay you 100% of the Principal Amount of your Notes if the Notes are not called and the Final Value is less than the Buffer Value. In this case, the Payment at Maturity you will be entitled to receive will be less than the Principal Amount and you will lose 1.3333% for each 1% that the Reference Return is less than -25.00%. You may lose up to 100% of your investment at maturity. Even with the Coupons received prior to or at maturity, your return on the Notes may be negative in this case.

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 6 months. 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.

Your return on the Notes is limited to the Principal Amount plus the Coupons, regardless of any appreciation in the value of the Reference Asset.

For each $1,000 Principal Amount, you will receive $1,000 at maturity plus the final Coupon, regardless of any appreciation in the value of the Reference Asset, 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 Reference Asset during the term of the Notes.

Higher Coupon Rates or lower Buffer Values are generally associated with Reference Assets 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 the Reference Asset. The greater the expected volatility with respect to the Reference Asset on the Trade Date, the higher the expectation as of the Trade Date that the value of the Reference Asset could close below the Buffer Value on the Final Valuation Date, indicating a higher expected risk of non-payment of Coupons or loss on the Notes. This greater expected risk will generally be reflected in a higher Coupon Rate than the yield payable on our conventional debt securities with a similar maturity, or in more favorable terms (such as a lower Buffer Value or a higher Coupon Rate) than for similar securities linked to the performance of the Reference Asset with a lower expected volatility as of the Trade Date. You should therefore understand that a relatively higher Coupon Rate may indicate an increased risk of loss. Further, a relatively lower Buffer Value may not necessarily indicate that the Notes have a greater likelihood of a repayment of principal at maturity. The volatility of the Reference Asset can change significantly over the term of the Notes. The value of the Reference Asset 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 Reference Asset and the potential to lose some or all of your principal at maturity.

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

The payments on the Notes will be based on the Official Closing Levels of the Reference Asset on the Final Valuation Date, subject to postponement certain Market Disruption Events. If the Notes are not called, even if the value of the Reference Asset is greater than or equal to the Buffer Value during the term of the Notes other than on the Final Valuation Date but then decreases on the Final Valuation Date to a value that is less than the Buffer Value, 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 Reference Asset prior to such decrease.

FWP-9 

Risks Relating to the Reference Asset

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

The policies of the reference sponsor of the Reference Asset, concerning additions, deletions and substitutions of the stocks included in the Reference Asset and the manner in which the reference sponsor takes account of certain changes affecting those stocks may affect the value of the Reference Asset. The policies of the reference sponsor could also affect the value 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 Reference Asset 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.

General Risk Factors

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

The Notes are senior unsecured debt obligations of the Issuer, HSBC, and are not, either directly or indirectly, an obligation of any third party. As further described in the accompanying prospectus supplement and prospectus, the Notes will rank on par with all of the other unsecured and unsubordinated debt obligations of HSBC, except such obligations as may be preferred by operation of law. Any payment to be made on the Notes, including any return of principal at maturity, depends on the ability of HSBC to satisfy its obligations as they come due. As a result, the actual and perceived creditworthiness of HSBC may affect the market value of the Notes and, in the event HSBC were to default on its obligations, you may not receive the amounts owed to you under the terms of the Notes.

The Notes are not insured or guaranteed by any governmental agency of the United States or any other jurisdiction.

The Notes are not deposit liabilities or other obligations of a bank and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency or program of the United States or any other jurisdiction. An investment in the Notes is subject to the credit risk of HSBC, and in the event that HSBC is unable to pay its obligations as they become due, you may not receive the full payments due on the Notes.

The Estimated Initial Value of the Notes, which will be determined by us on the Trade Date, is expected to be less than the price to public and may differ from the market value of the Notes in the secondary market, if any.

The Estimated Initial Value of the Notes will be calculated by us on the Trade Date and is expected to be less than the price to public. The Estimated Initial Value will reflect our and our affiliates’ internal funding rate, which is the borrowing rate paid to issue market-linked securities, as well as the mid-market value of the embedded derivatives in the Notes. This internal funding rate is typically lower than the rate we would use when we issue conventional fixed or floating rate debt securities. As a result of the difference between our internal funding rate and the rate we would use when we issue conventional fixed or floating rate debt securities, the Estimated Initial Value of the Notes may be lower if it were based on the prices at which our fixed or floating rate debt securities trade in the secondary market. In addition, if we were to use the rate we use for our conventional fixed or floating rate debt issuances, we would expect the economic terms of the Notes to be more favorable to you. We will determine the value of the embedded derivatives in the Notes by reference to our or our affiliates’ internal pricing models. These pricing models consider certain assumptions and variables, which can include volatility and interest rates. Different pricing models and assumptions could provide valuations for the Notes that are different from our Estimated Initial Value. These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect. The Estimated Initial Value does not represent a minimum price at which we or any of our affiliates would be willing to purchase your Notes in the secondary market (if any exists) at any time.

The price of your Notes in the secondary market, if any, immediately after the Trade Date is expected to be less than the price to public.

The price to public takes into account certain costs. These costs, which will be used or retained by us or one of our affiliates, include the underwriting discount, our affiliates’ projected hedging profits (which may or may not be realized) for assuming risks inherent in hedging our obligations under the Notes, and the costs associated with structuring and hedging our obligations under the Notes. If you were to sell your Notes in the secondary market, if any, the price you would receive for your Notes may be less than the price you paid for them because secondary market prices will not take into account these costs. The price of your Notes in the secondary market, if any, at any time after issuance will vary based on many factors, including the value of the Reference Asset and changes in market conditions, and

FWP-10 

cannot be predicted with accuracy. The Notes are not designed to be short-term trading instruments, and you should, therefore, be able and willing to hold the Notes to maturity. Any sale of the Notes prior to maturity could result in a loss to you.

If we were to repurchase your Notes immediately after the Original Issue Date, the price you receive may be higher than the Estimated Initial Value of the Notes.

Assuming that all relevant factors remain constant after the Original Issue Date, the price at which HSBC Securities (USA) Inc. may initially buy or sell the Notes in the secondary market, if any, and the value that may initially be used for customer account statements, if any, may exceed the Estimated Initial Value on the Trade Date for a temporary period expected to be approximately 3 months after the Original Issue Date. This temporary price difference may exist because, in our discretion, we may elect to effectively reimburse to investors a portion of the estimated cost of hedging our obligations under the Notes and other costs in connection with the Notes that we will no longer expect to incur over the term of the Notes. We will make such discretionary election and determine this temporary reimbursement period on the basis of a number of factors, including the tenor of the Notes and any agreement we may have with the distributors of the Notes. The amount of our estimated costs which we effectively reimburse to investors in this way may not be allocated ratably throughout the reimbursement period, and we may discontinue such reimbursement at any time or revise the duration of the reimbursement period after the Original Issue Date of the Notes based on changes in market conditions and other factors that cannot be predicted.

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

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

The Notes lack liquidity.

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

Potential conflicts of interest may exist.

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

Uncertain tax treatment.

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 the Reference Asset relative to the Initial Value. We cannot predict the Official Closing Level of the Reference Asset 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 Reference Asset or the return on the Notes.

The table and examples below illustrate how the 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 the Reference Asset. 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:

🞂Principal Amount:	$1,000
🞂Hypothetical Initial Value:	1,000.00*
🞂Hypothetical Call Threshold:	1,000.00 (100.00% of the Initial Value)
🞂Hypothetical Buffer Value:	750.00 (75.00% of the Initial Value)
🞂Downside Leverage Factor:	1/0.75 (1.3333x)
🞂Hypothetical Coupon Rate:	8.00% per annum (4.00% for each semi-annual period in which it is payable). The actual Coupon Rate will be at least 8.00% per annum and will be determined on the Trade Date. If the Notes are not called, the Coupons paid over the term of the Notes would total $120.00 per $1,000 Principal Amount.

* 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 the Reference Asset. The actual Initial Value of the Reference Asset will be determined on the Pricing Date and set forth in the final pricing supplement to which this free writing prospectus relates.

Summary of the Examples

	Notes Are Called on an Observation Date	Notes Are Not Called on Any Observation Dates
	Example 1	Example 2	Example 3
Initial Value	1,000.00	1,000.00	1,000.00
Call Threshold	1,000.00	1,000.00	1,000.00
Buffer Value	750.00	750.00	750.00
Official Closing Level / Percentage Change on the:
First Observation Date	787.50 / -21.25%	810.00 / -19.00%	810.00 / -19.00%
Second Observation Date	1,200.00 / 20.00%	787.50 / -21.25%	600.00 / -40.00%
Final Valuation Date	N/A	780.00 / -22.00%	400.00 / -60.00%
Coupon Payment Amounts Prior to Maturity or Call	1 x $40.00 = $40.00	2 x $40.00 = $80.00	2 x $40.00 = $80.00
Payment if Notes are Called	$1,040.00	N/A	N/A
Payment at Maturity	N/A	$1,040.00	$1,000 + [$1,000 x (-60.00% + 25.00%) x 1.3333] + $40.00 = $573.33
Return of the Notes	8.00%	12.00%	-34.667%

FWP-12 

Example 1—The Official Closing Level of the Reference Asset on the second Observation Date is greater than or equal to the Call Threshold.

Initial Value	Official Closing Level
1,000.00	1,250.00 (125.00% of Initial Value)

Payment Upon a Call: $1,040.00

Because the Official Closing Level of the Reference Asset on the second Observation Date is at or above the Call Threshold, the Notes will be called and you will receive $1,040.00 per Note, reflecting the Principal Amount plus the Coupon. When added to the Coupon payments of $40.00 received in respect of the previous Coupon Payment Dates, we will have paid you a total of $1,080.00 per Note, resulting in a 8.00% return on the Notes. No extra payment will be made on account of the Reference Asset closing above the Initial Value.

Example 2— The Notes are not called and the Final Value is greater than or equal to the Buffer Value.

Initial Value	Final Value
1,000.00	780.00 (78.00% of Initial Value)

Reference Return:	-22.00%
Payment at Maturity:	$1,040.00

Because the Final Value is greater than or equal to the Buffer Value, you will receive $1,040.00 per Note, reflecting the Principal Amount plus the final Coupon.

When added to the Coupon payments of $80.00 received prior to maturity, we will have paid you a total of $1,120.00 per Note, resulting in a 12.00% return on the Notes.

FWP-13 

Example 3—The Notes are not called and the Final Value is less than the Buffer Value.

Initial Value	Final Value
1,000.00	400.00 (40.00% of Initial Value)

Reference Return:	-60.00%
Payment at Maturity:	$573.33

Because the Final Value is less than the Buffer Value, you will receive $540.00 per $1,000 Principal Amount, calculated as follows:

Final Settlement Value = $1,000 + [$1,000 × (Reference Return + 25.00%)
× Downside Leverage Factor] + final Coupon.

$1,000 + [$1,000 x (-60.00% + 25.00%) x 1.3333] + $40.00= $573.33

When added to the Coupon payments of $80.00 received prior to maturity, we will pay you a total of $653.33, resulting in a -34.667% return on the Notes.

If the Notes are not called and the Final Value is less than the Buffer Value, you will be exposed to any decrease in the value of the Reference Asset on a 1.3333:1 basis and could lose up to 100% of your principal at maturity.

DESCRIPTION OF THE REFERENCE ASSET

Description of the NDX The Nasdaq-100 Index® ("NDX") is a modified market capitalization-weighted index of 100 of the largest non-financial companies listed on the NASDAQ Stock Market based on market capitalization. It does not contain securities of financial companies (based on the Financials industry classification according to the Industry Classification Benchmark). Each underlying stock's influence on the level of the NDX is directly proportional to the value of its share weight. For more information about the NDX, see “The Nasdaq-100 Index®” beginning on page S-31 of the accompanying Equity Index Underlying Supplement.

Historical Performance of the NDX The following graph sets forth the historical performance of the NDX based on the daily historical closing values from April 6, 2013 through April 6, 2023. We obtained the closing values below from the Bloomberg Professional® service. We have not undertaken any independent review of, or made any due diligence inquiry with respect to, the information obtained from the Bloomberg Professional® service.

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

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 the Reference Asset, and the accelerated Maturity Date will be three business days after the accelerated Final Valuation Date. If a Market Disruption Event exists with respect to the 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 following the postponed accelerated Final Valuation Date. If the Notes have become immediately due and payable following an Event of Default, you will not be entitled to any additional payments with respect to the Notes. For more information, see “Description of Debt Securities — Senior Debt Securities — Events of Default” in the accompanying prospectus.

SUPPLEMENTAL PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

We have appointed HSBC Securities (USA) Inc., an affiliate of HSBC, as the agent for the sale of the Notes. Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc. will purchase the Notes from HSBC at the price to public less the underwriting discount set forth on the cover page of the pricing supplement to which this document relates, for distribution to other registered broker-dealers or will offer the Notes directly to investors. HSBC Securities (USA) Inc. proposes to offer the Notes at the price to public set forth on the cover page of this document. HSBC USA Inc. or one of our affiliates may pay varying underwriting discounts of up to 0.05% per $1,000 Principal Amount in connection with the distribution of the Notes to other registered broker-dealers.

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

In addition, HSBC Securities (USA) Inc. or another of its affiliates or agents may use the pricing supplement to which this free writing prospectus relates in market-making transactions after the initial sale of the Notes, but is under no obligation to make a market in the Notes and may discontinue any market-making activities at any time without notice.

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

We expect that delivery of the Notes will be made against payment for the Notes on or about the Original Issue Date set forth on the inside cover page of this document, which is more than two business days following the Trade Date. Under Rule 15c6-1 under the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in two business days, unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes more than two business days prior to the Original Issue Date will be required to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement, and should consult their own advisors.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

There is no direct legal authority as to the proper tax treatment of the Notes, and therefore significant aspects of the tax treatment of the Notes are uncertain as to both the timing and character of any inclusion in income in respect of the Notes. Under one approach, each Note should be treated as a put option written by you (the “Put Option”) that permits us to “cash settle” the Put Option, and a deposit with us of cash in an amount equal to the Principal Amount of the Note (the “Deposit”) to secure your potential obligation under the Put Option, as described in the accompanying prospectus supplement 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 a Put Option and a Deposit.”  We intend to treat the Notes consistent with this approach, and we intend to treat the Deposits as non-contingent debt instruments for U.S. federal income tax purposes. Pursuant to the terms of the Notes, you agree to treat each Note as consisting of the Deposit and the Put Option 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 consisting of the Deposit and the Put Option for all U.S. federal income tax purposes. 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 above. We do not plan to request a ruling from the Internal Revenue Service (the “IRS”) regarding the tax treatment of the Notes, and the IRS or a court may not agree with the tax treatment described herein.

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.

FWP-16 

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.

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 a Put Option and a Deposit” 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). For purposes of dividing the annual coupon rate of 8.00% on the Notes among interest on the Deposit and Put Premium, [●]% constitutes interest on the Deposit and [●]% constitutes Put Premium.

If the Notes are redeemed prior to maturity, you should recognize the total Put Premium received as short-term capital gain at that time.

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 coupon payments on the Notes is uncertain, the entire amount of the coupon payments 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 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.
