**Investor Considerations**

**The securities are not appropriate for all investors. The securities may be an appropriate investment for investors who:**

● seek at least 121% (to be determined on the pricing date) leveraged exposure to the upside performance of the Index if the ending level is greater than the starting level;

● desire to limit downside exposure to the Index through the buffer amount;

● are willing to accept the risk that, if the ending level is less than the starting level by more than the buffer amount, they will lose some, and possibly up to 75%, of the face amount per security at maturity;

● are willing to forgo interest payments on the securities and dividends on the securities included in the Index; and

● are willing to hold the securities until maturity.

**The securities may not be an appropriate investment for investors who:**

● are unwilling to accept the risk that the ending level of the Index may decrease from the starting level by more than the buffer amount;

● seek full return of the face amount of the securities at stated maturity;

● are unwilling to purchase securities with an estimated value as of the pricing date that is lower than the original offering price, and may be as low as the lower estimate set forth on the cover page;

● seek current income;

● are unwilling to accept the risk of exposure to the Index;

● seek exposure to the Index but are unwilling to accept the risk/return trade-offs inherent in the maturity payment amount for the securities;

● are unwilling to accept the credit risk of HSBC to obtain exposure to the Index generally, or to the exposure to the Index that the securities provide specifically; or

● prefer the lower risk of conventional fixed income investments with comparable maturities issued by companies with comparable credit ratings.

**The considerations identified above are not exhaustive. Whether or not the securities are an appropriate investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisors have carefully considered the appropriateness of an investment in the securities in light of your particular circumstances. You should also review carefully the "Selected Risk Considerations" herein and "Risk Factors" in the accompanying underlying supplement, product supplement and prospectus supplement, for risks related to an investment in the securities. For more information about the Index, please see "The Index" below.**

**Selected Risk Considerations** 

The securities have complex features and investing in the securities will involve risks not associated with an investment in conventional debt securities. Some of the risks that apply to an investment in the securities are summarized below, but we urge you to read the more detailed explanation of the risks relating to the securities generally in the "Risk Factors" beginning on page PS-5 of the accompanying product supplement, S-1 of the accompanying underlying supplement, page S-1 of the prospectus supplement and page 1 of the prospectus. You should reach an investment decision only after you have carefully considered with your advisors the appropriateness of an investment in the securities in light of your particular circumstances.

**<u>Risks Relating To The Structure Of The Securities</u>**

**If The Ending Level Is Less Than The Threshold Level, You Will Lose Some, And Possibly Up To 75%, Of The Face Amount Of Your Securities At Maturity.**

We will not repay you a fixed amount on the securities on the stated maturity date. The maturity payment amount will depend on the direction of and percentage change in the ending level of the Index relative to the starting level and the other terms of the securities. Because the level of the Index will be subject to market fluctuations, the maturity payment amount may be more or less, and possibly significantly less, than the face amount of your securities.

If the ending level is less than the threshold level, the maturity payment amount will be less than the face amount and you will have 1-to-1 downside exposure to the decrease in the level of the Index in excess of the buffer amount, resulting in a loss of 1% of the face amount for every 1% decline in the Index in excess of the buffer amount. The threshold level is 75% of the starting level. As a result, if the ending level is less than the threshold level, you will lose some, and possibly up to 75%, of the face amount per security at maturity. This is the case even if the level of the Index is greater than or equal to the starting level or the threshold level at certain times during the term of the securities.

Even if the ending level is greater than the starting level, the maturity payment amount may only be slightly greater than the face amount, and your yield on the securities may be less than the yield you would earn if you bought a traditional interest-bearing debt security of HSBC or another issuer with a similar credit rating with the same stated maturity date.

**No Periodic Interest Will Be Paid On The Securities.**

No periodic payments of interest will be made on the securities. However, if the agreed-upon tax treatment is successfully challenged by the Internal Revenue Service (the "<u>IRS</u>"), you may be required to recognize taxable income over the term of the securities. You should review the section of this free writing prospectus entitled "United States Federal Tax Considerations."

**The Stated Maturity Date May Be Postponed If The Calculation Day Is Postponed.**

The stated maturity date will be postponed if the originally scheduled calculation day is not a trading day or if the calculation agent determines that a market disruption event has occurred or is continuing on that day. If such a postponement occurs, the stated maturity date will be the later of (i) the initial stated maturity date and (ii) three business days after the calculation day as postponed.

**<u>Risk Relating To The Credit Risk Of HSBC</u>**

**The Securities Are Subject To The Credit Risk Of HSBC USA Inc.**

The securities are our obligations exclusively and are not, either directly or indirectly, an obligation of any third party. Any amounts payable under the securities are subject to our creditworthiness, and you will have no ability to pursue any securities included in the Index for payment. As a result, our actual and perceived creditworthiness and actual or anticipated decreases in our credit ratings may affect the value of the securities and, in the event we were to default on our obligations, you may not receive any amounts owed to you under the terms of the securities. See "Description of Senior Debt Securities—Events of Default" in the prospectus.

**<u>Risks Relating To The Estimated Value Of The Securities And Any Secondary Market</u>**

**The Estimated Initial Value Of The Securities, Which Will Be Determined By Us On The Pricing Date, Is Expected To Be Less Than The Original Offering Price And May Differ From The Market Value Of The Securities In The Secondary Market, If Any.**

The estimated initial value of the securities will be calculated by us on the pricing date and is expected to be less than the original offering price. 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 securities. 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 securities 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 securities to be more favorable to you. We will determine the value of the embedded derivatives in the securities 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 securities 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 securities in the secondary market (if any exists) at any time.

**The Price Of Your Securities In The Secondary Market, If Any, Immediately After The Pricing Date Is Expected To Be Less Than The Original Offering Price.** 

The original offering price takes into account certain costs. These costs include the underwriting discount, our hedge counterparty's projected hedging profits (which may or may not be realized) for assuming risks inherent in hedging our obligations under the securities and the costs associated with structuring and hedging our obligations under the securities. These costs, except for the underwriting discount, will be used or retained by us or one of our affiliates. If you were to sell your securities in the secondary market, if any, the price you would receive for your securities 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 securities in the secondary market, if any, at any time after issuance will vary based on many factors, including the level of the Index and changes in market conditions, and cannot be predicted with accuracy. The securities are not designed to be short-term trading instruments, and you should, therefore, be able and willing to hold the securities to maturity. Any sale of the securities prior to maturity could result in a loss to you.

**If HSBC Securities (USA) Inc. Or The Agent Were To Repurchase Your Securities Immediately After The Issue Date, The Price You Receive May Be Higher Than The Estimated Initial Value Of The Securities.**

Assuming that all relevant factors remain constant after the issue date, the price at which HSBC Securities (USA) Inc. or the agent may initially buy or sell the securities in the secondary market, if any, and the value 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 3 months after the issue date. This temporary price difference may exist because, in its discretion, HSBC Securities (USA) Inc. or the agent may elect to effectively reimburse to investors a portion of the estimated hedging cost and other costs in connection with the securities that will no longer be incurred over the term of the securities. This discretionary election will be made, and the temporary reimbursement period will be determined, on the basis of a number of factors, including the tenor of the securities and any agreement we may have with the distributors of the securities. The amount of the estimated costs which may be effectively reimbursed to investors in this way may not be allocated ratably throughout the reimbursement period, and such reimbursement may be discontinued at any time, or the duration of the reimbursement period may be shortened after the issue date of the securities based on changes in market conditions and other factors that cannot be predicted.

**The Value Of The Securities Prior To Maturity Will Be Affected By Numerous Factors, Some Of Which Are Related In Complex Ways.**

The value of the securities prior to maturity will be affected by the then-current level of the Index, interest rates at that time and a number of other factors, some of which are interrelated in complex ways. The effect of any one factor may be offset or magnified by the effect of another factor. The following factors, among others, are expected to affect the value of the securities: Index performance; volatility of the Index; economic and other conditions generally; interest rates; dividend yields on securities included in the Index; our credit ratings or credit spreads; time remaining to maturity; volatility of currency exchange rates; and correlation between currency exchange rates and the Index. When we refer to the "value" of your security, we mean the value you could receive for your security if you are able to sell it in the open market before the stated maturity date.

You should understand that the impact of one of the factors specified above, such as a change in interest rates, may offset some or all of any change in the value of the securities attributable to another factor, such as a change in the level of the Index. Because numerous factors are expected to affect the value of the securities, changes in the level of the Index may not result in a comparable change in the value of the securities.

**The Securities Will Not Be Listed On Any Securities Exchange And We Do Not Expect A Trading Market For The Securities To Develop.**

The securities will not be listed on any securities exchange. Although Wells Fargo Securities and/or its affiliates may purchase the securities from holders, they are not obligated to do so and are not required to make a market for the securities. There can be no assurance that a secondary market will develop for the securities. Because we do not expect that any market makers will participate in a secondary market for the securities, the price at which you may be able to sell your securities is likely to depend on the price, if any, at which Wells Fargo Securities and/or its affiliates are willing to buy your securities.

If a secondary market does exist, it may be limited. Accordingly, there may be a limited number of buyers if you decide to sell your securities prior to maturity. This may affect the price you receive upon such sale. Consequently, you should be willing to hold the securities to maturity.

**<u>Risks Relating To The Index</u>**

**Any Payments On The Securities Will Depend Upon The Performance Of The Index And Therefore The Securities Are Subject To The Following Risks, Each As Discussed In More Detail In The Accompanying Product Supplement.** 

&nbsp;&nbsp;&nbsp;&nbsp;· **Investing In The Securities Is Not The Same As Investing In The Index.** Investing in the securities is not equivalent to investing in the Index. As an investor in the securities,

&nbsp;&nbsp;&nbsp;&nbsp;· **Changes That Affect The Index May Adversely Affect The Value Of The Securities And Any Payments On The Securities.** 

&nbsp;&nbsp;&nbsp;&nbsp;· **We Cannot Control Actions By Any Of The Unaffiliated Companies Whose Securities Are Included In The Index.** 

&nbsp;&nbsp;&nbsp;&nbsp;· **We And Our Affiliates Have No Affiliation With The Index Sponsor And Have Not Independently Verified Its Public Disclosure Of Information.** 

**An Investment in the Securities Is Subject to Risks Associated with Foreign Securities Markets.**

The Index includes the securities of foreign companies and you should be aware that investments in securities linked to the value of foreign equity securities involve particular risks. Foreign securities markets may have less liquidity and may be more volatile than the U.S. securities markets, and market developments may affect foreign markets differently than U.S. securities markets. Direct or indirect government intervention to stabilize a foreign securities market, as well as cross-shareholdings in foreign companies, may affect trading prices and volumes in those markets. Also, there is generally less publicly available information about non-U.S. companies that are not subject to the reporting requirements of the Securities and Exchange Commission, and non-U.S. companies are subject to accounting, auditing and financial reporting standards and requirements that differ from those applicable to U.S. reporting companies.

The prices and performance of securities of non-U.S. companies are subject to political, economic, financial, military and social factors which could negatively affect foreign securities markets, including the possibility of recent or future changes in a foreign government's economic, monetary and fiscal policies, the possible imposition of, or changes in, currency exchange laws or other laws or restrictions applicable to foreign companies or investments in foreign equity securities, the possibility of imposition of withholding taxes on dividend income, the possibility of fluctuations in the rate of exchange between currencies, the possibility of outbreaks of hostility or political instability and the possibility of natural disaster or adverse public health developments. Moreover, the relevant non-U.S. economies may differ favorably or unfavorably from the U.S. economy in important respects, such as growth of gross national product, rate of inflation, trade surpluses or deficits, capital reinvestment, resources and self-sufficiency.

The securities included in the Index may be listed on a foreign stock exchange. A foreign stock exchange may impose trading limitations intended to prevent extreme fluctuations in individual security prices and may suspend trading in certain circumstances. These actions could limit variations in the closing level of the Index which could, in turn, adversely affect the value of the securities.

**<u>Risks Relating To Conflicts Of Interest</u>**

**Our Economic Interests And Those Of Any Dealer Participating In The Offering Of Securities Will Potentially Be Adverse To Your Interests.**

You should be aware of the following ways in which our economic interests and those of any dealer participating in the distribution of the securities, which we refer to as a "participating dealer," will potentially be adverse to your interests as an investor in the securities. In engaging in certain of the activities described below and as discussed in more detail in the accompanying product supplement, our affiliates or any participating dealer or its affiliates may take actions that may adversely affect the value of and your return on the securities, and in so doing they will have no obligation to consider your interests as an investor in the securities. Our affiliates or any participating dealer or its affiliates may realize a profit from these activities even if investors do not receive a favorable investment return on the securities.

**Hypothetical Examples and Returns**

The payout profile, return table and examples below illustrate hypothetical payments at maturity for a $1,000 face amount security on a hypothetical offering of securities under various scenarios, with the assumptions set forth in the table below. The terms used for purposes of these hypothetical examples do not represent the actual starting level or threshold level. The hypothetical starting level of 100.00 has been chosen for illustrative purposes only and does not represent the actual starting level. The actual starting level and threshold level will be determined on the pricing date and will be set forth under "Terms of the Securities" above. For historical data regarding the actual closing levels of the Index, see the historical information set forth herein. The payout profile, return table and examples below assume that an investor purchases the securities for $1,000 per security. These examples are for purposes of illustration only and the values used in the examples may have been rounded for ease of analysis. The actual amount you receive at stated maturity and the resulting pre-tax total rate of return will depend on the actual terms of the securities.

<sup>(1)</sup> The index return is equal to the percentage change from the starting level to the ending level (i.e., the ending level *minus* starting level, *divided* by starting level).

**Hypothetical Examples Of Payment At Stated Maturity** 

**Example 1. The maturity payment amount is greater than the face amount:** 

---

| | |
|:---|:---|
|  | **The Index** |
| &nbsp;&nbsp;**Hypothetical starting level:** | 100.00 |
| &nbsp;&nbsp;**Hypothetical ending level:** | 110.00 |
| &nbsp;&nbsp;**Hypothetical threshold level:** | 75.00 |
| &nbsp;&nbsp; **Hypothetical index return** <br> **(ending level – starting level)/starting level:**  | 10.00% |

---

Because the hypothetical ending level is greater than the hypothetical starting level, the maturity payment amount per security would be equal to the face amount of $1,000 *plus* a positive return equal to:

$1,000 × index return × hypothetical upside participation rate

$1,000 × 10.00% × 121.00%

= $1,121.00

On the stated maturity date you would receive $1,121.00 per security.

**Example 2. Maturity payment amount is equal to the face amount:**

---

| | |
|:---|:---|
|  | **The Index** |
| &nbsp;&nbsp;**Hypothetical starting level:** | 100.00 |
| &nbsp;&nbsp;**Hypothetical ending level:** | 95.00 |
| &nbsp;&nbsp;**Hypothetical threshold level:** | 75.00 |
| &nbsp;&nbsp; **Hypothetical index return** <br> **(ending level – starting level)/starting level:** | -5.00% |

---

Because the hypothetical ending level is less than the hypothetical starting level, but not by more than the buffer amount, you would not lose any of the face amount of your securities.

On the stated maturity date you would receive $1,000.00 per security.

**Example 3. Maturity payment amount is less than the face amount:**

---

| | |
|:---|:---|
|  | **The Index** |
| &nbsp;&nbsp;**Hypothetical starting level:** | 100.00 |
| &nbsp;&nbsp;**Hypothetical ending level:** | 50.00 |
| &nbsp;&nbsp;**Hypothetical threshold level:** | 75.00 |
| &nbsp;&nbsp; **Hypothetical index return**<br> **(ending level – starting level)/starting level:** | -50.00% |

---

Because the hypothetical ending level is less than the hypothetical starting level by more than the buffer amount, you would lose a portion of the face amount of your securities and receive the maturity payment amount equal to:

$1,000 + [$1,000 × (index return + buffer amount)]

$1,000 + [$1,000 × (-50.00% + 25%)]

= $750.00

On the stated maturity date you would receive $750.00 per security.

**U.S. Federal Income Tax Considerations**

You should carefully consider, among other things, the matters set forth in the section "U.S. Federal Income Tax Considerations" in the accompanying prospectus supplement. The following discussion summarizes the U.S. federal income and estate tax consequences of the purchase, beneficial ownership, and disposition of the securities. This summary supplements the section "U.S. Federal Income Tax Considerations" in the accompanying prospectus supplement and supersedes it to the extent inconsistent therewith.

There is no direct legal authority as to the proper tax treatment of the securities, and therefore significant aspects of the tax treatment of the securities are uncertain as to both the timing and character of any inclusion in income in respect of the securities. Under one approach, a security should be treated as a pre-paid executory contract with respect to the Index. We intend to treat the securities consistent with this approach. Pursuant to the terms of the securities, you agree to treat the securities 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 HSBC, in the opinion of HSBC's special U.S. tax counsel, Mayer Brown LLP, it is reasonable to treat a security as a pre-paid executory contract with respect to the Index. Pursuant to this approach, we do not intend to report any income or gain with respect to the securities prior to their maturity or an earlier sale, call or exchange and we intend to treat any gain or loss upon maturity or an earlier sale, call or exchange as long-term capital gain or loss, provided you have held the security for more than one year at such time for U.S. federal income tax purposes. If the securities are held by the same U.S. holder until maturity, that holder's holding period will generally include the maturity date.

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

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, 2027. Based on the terms of the securities and market conditions as of the date of this free writing prospectus, the Issuer expects that the securities will not be treated as "delta-one" instruments and, therefore, non-U.S. holders should not be subject to withholding on dividend equivalent payments, if any, under the securities. A determination that the securities are not subject to Section 871(m) is not binding on the Internal Revenue Service, and the Internal Revenue Service may disagree with this treatment. Moreover, Section 871(m) is complex and its application may depend on your particular circumstances, including your other transactions. It is possible that the securities could be treated as deemed reissued for U.S. federal income tax purposes upon the occurrence of certain events affecting the Index or the securities, and following such occurrence the securities 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 Index or the securities should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the securities 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.

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