[424B2] iPath Series B S&P 500 VIX Mid-Term Futures ETN Prospectus Supplement

Rhea-AI Filing Summary

Barclays Bank PLC is offering Buffered SupertrackSM Notes linked to the Russell 2000® Index, maturing on 2 February 2028.

Principal terms:

• Denomination: US$1,000 (and multiples thereof)
• Upside participation: 2.0× index return, capped at 30.25%. A ≥15.125 % rise in RTY delivers the maximum payment of $1,302.50 per Note.
• Downside protection: 10 % buffer. If the index declines ≤10 %, investors receive par. Beyond that, loss equals the decline exceeding −10 %, up to a 90 % maximum loss.
• Key dates: Initial Valuation – 28 July 2025; Issue – 31 July 2025; Final Valuation – 28 Jan 2028; Maturity – 2 Feb 2028.
• Pricing & distribution: Issue price 100 % (US$1,000). Underwriter commission up to 2.75 % (US$27.50). Investors in fee-based accounts may pay US$972.50–1,000.
• Issuer-estimated value: US$903–963, below issue price, reflecting internal funding rates and distribution costs.
• Listing: None; the Notes are illiquid and may trade at discounts.

Risk highlights (see “Risk Factors”):

• Credit risk: Unsecured, unsubordinated claims on Barclays Bank PLC; no FDIC or FSCS protection.
• U.K. Bail-in: Holders expressly consent to potential write-down or conversion under the U.K. Banking Act 2009.
• Market risk: Performance depends solely on Russell 2000 level at final valuation; interim movements irrelevant.
• Valuation & liquidity: Secondary prices likely below issue price due to bid-ask spreads, commissions and issuer spread.

Investors seeking enhanced, but capped, equity exposure with modest downside buffer may consider the Notes; however, they must be comfortable with issuer credit exposure, bail-in risk, capped upside, potential principal loss beyond −10 %, and lack of secondary market depth.

Positive

• Leveraged upside: 2× participation up to a 30.25% cap offers enhanced returns if Russell 2000 rises modestly.
• Downside buffer: 10% protection shields principal from small market declines.

Negative

• Significant downside risk: Investors lose 1% of principal for every 1% index drop beyond −10%, up to a 90% loss.
• Capped gains: Maximum return limited to 30.25%, underperforming direct equity ownership in strong bull scenarios.
• Issuer & bail-in risk: Unsecured claim on Barclays; notes can be written down or converted under U.K. Bail-in Power.
• Estimated value below par: Internal valuation US$903–963 implies immediate economic cost of up to 9.7%.
• Illiquidity: No exchange listing; secondary market, if any, may be thin and at discounts.

Insights

Structured-Product Analyst

TL;DR: 2× upside to 30.25%, 10% buffer, uncapped downside to −90%, estimated value 3.7–9.7% below issue; credit & bail-in risk.

These Buffered Supertrack Notes provide leveraged participation in small-cap equities through the Russell 2000. Investors obtain a 200% upside coefficient, but only until the 30.25% cap, translating to a maximum gross gain of 30.25% over ~2.5 years—about 11.3% IRR. Downside begins after a 10% cushion; every additional 1% decline results in a 1% principal hit, exposing holders to large losses in a bear market. The embedded option structure and 2.75% selling concession leave an estimated value of US$903–963, indicating an upfront cost of 3.7–9.7% to investors. Notes are unsecured; consent to U.K. Bail-in adds statutory write-down risk. With no listing, liquidity is dealer-driven. Overall, the product suits tactical investors tolerant of issuer credit risk and a hard cap on upside, but it offers limited appeal versus direct index exposure or buffered ETFs.

This preliminary pricing supplement and the accompanying prospectus, prospectus supplement and underlying supplement do not constitute an offer to sell these Notes, and we are not soliciting an offer to buy these Notes in any state where the offer or sale is not permitted.

CONSENT TO U.K. BAIL-IN POWER

Notwithstanding and to the exclusion of any other term of the Notes or any other agreements, arrangements or understandings between us and any holder or beneficial owner of the Notes (or the trustee on behalf of the holders of the Notes), by acquiring the Notes, each holder or beneficial owner of the Notes acknowledges, accepts, agrees to be bound by, and consents to the exercise of, any U.K. Bail-in Power by the relevant U.K. resolution authority.

Under the U.K. Banking Act 2009, as amended, the relevant U.K. resolution authority may exercise a U.K. Bail-in Power in circumstances in which the relevant U.K. resolution authority is satisfied that the resolution conditions are met. These conditions include that a U.K. bank or investment firm is failing or is likely to fail to satisfy the Financial Services and Markets Act 2000 (the “FSMA”) threshold conditions for authorization to carry on certain regulated activities (within the meaning of section 55B FSMA) or, in the case of a U.K. banking group company that is a European Economic Area (“EEA”) or third country institution or investment firm, that the relevant EEA or third country relevant authority is satisfied that the resolution conditions are met in respect of that entity.

The U.K. Bail-in Power includes any write-down, conversion, transfer, modification and/or suspension power, which allows for (i) the reduction or cancellation of all, or a portion, of the principal amount of, or interest on, or any other amounts payable on, the Notes; (ii) the conversion of all, or a portion, of the principal amount of, or interest on, or any other amounts payable on, the Notes into shares or other securities or other obligations of Barclays Bank PLC or another person (and the issue to, or conferral on, the holder or beneficial owner of the Notes of such shares, securities or obligations); (iii) the cancellation of the Notes and/or (iv) the amendment or alteration of the maturity of the Notes, or the amendment of the amount of interest or any other amounts due on the Notes, or the dates on which interest or any other amounts become payable, including by suspending payment for a temporary period; which U.K. Bail-in Power may be exercised by means of a variation of the terms of the Notes solely to give effect to the exercise by the relevant U.K. resolution authority of such U.K. Bail-in Power. Each holder and beneficial owner of the Notes further acknowledges and agrees that the rights of the holders or beneficial owners of the Notes are subject to, and will be varied, if necessary, solely to give effect to, the exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority. For the avoidance of doubt, this consent and acknowledgment is not a waiver of any rights holders or beneficial owners of the Notes may have at law if and to the extent that any U.K. Bail-in Power is exercised by the relevant U.K. resolution authority in breach of laws applicable in England.

For more information, please see “Selected Risk Considerations—Risks Relating to the Issuer—You May Lose Some or All of Your Investment If Any U.K. Bail-in Power Is Exercised by the Relevant U.K. Resolution Authority” in this pricing supplement as well as “U.K. Bail-in Power,” “Risk Factors—Risks Relating to the Securities Generally—Regulatory action in the event a bank or investment firm in the Group is failing or likely to fail, including the exercise by the relevant U.K. resolution authority of a variety of statutory resolution powers, could materially adversely affect the value of any securities” and “Risk Factors—Risks Relating to the Securities Generally—Under the terms of the securities, you have agreed to be bound by the exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority” in the accompanying prospectus supplement.

ADDITIONAL INFORMATION REGARDING OUR ESTIMATED VALUE OF THE NOTES

The range of the estimated values of the Notes referenced above may not correlate on a linear basis with the range of any other term of the Notes as may be set forth in this pricing supplement. We determined the size of such range based on prevailing market conditions, as well as the anticipated duration of the marketing period for the Notes. The final terms for the Notes will be determined on the date the Notes are initially priced for sale to the public, which we refer to as the Initial Valuation Date, based on prevailing market conditions on or prior to the Initial Valuation Date, and will be communicated to investors either orally or in a final pricing supplement.

Our internal pricing models take into account a number of variables and are based on a number of subjective assumptions, which may or may not materialize, typically including volatility, interest rates, and our internal funding rates. Our internal funding rates (which are our internally published borrowing rates based on variables such as market benchmarks, our appetite for borrowing, and our existing obligations coming to maturity) may vary from the levels at which our benchmark debt securities trade in the secondary market. Our estimated value on the Initial Valuation Date is based on our internal funding rates. Our estimated value of the Notes may be lower if such valuation were based on the levels at which our benchmark debt securities trade in the secondary market.

Our estimated value of the Notes on the Initial Valuation Date is expected to be less than the initial issue price of the Notes. The difference between the initial issue price of the Notes and our estimated value of the Notes is a result of several factors, including any sales commissions to be paid to Barclays Capital Inc. or another affiliate of ours, any selling concessions, discounts, commissions or fees (including any structuring or other distribution related fees) to be allowed or paid to non-affiliated intermediaries, the estimated profit that we or any of our affiliates expect to earn in connection with structuring the Notes, the estimated cost which we may incur in hedging our obligations under the Notes, and estimated development and other costs which we may incur in connection with the Notes.

Our estimated value on the Initial Valuation Date is not a prediction of the price at which the Notes may trade in the secondary market, nor will it be the price at which Barclays Capital Inc. may buy or sell the Notes in the secondary market. Subject to normal market and funding conditions, Barclays Capital Inc. or another affiliate of ours intends to offer to purchase the Notes in the secondary market but it is not obligated to do so.

Assuming that all relevant factors remain constant after the Initial Valuation Date, the price at which Barclays Capital Inc. may initially buy or sell the Notes in the secondary market, if any, and the value that we may initially use for customer account statements, if we provide any customer account statements at all, may exceed our estimated value on the Initial Valuation Date for a temporary period expected to be approximately six months after the Issue Date 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 which we will no longer expect to incur over the term of the Notes. We made such discretionary election and determined this temporary reimbursement period on the basis of a number of factors, which may include the tenor of the Notes and/or 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 initial Issue Date of the Notes based on changes in market conditions and other factors that cannot be predicted.

We urge you to read the “Selected Risk Considerations” beginning on page PS-10 of this pricing supplement.

You may revoke your offer to purchase the Notes at any time prior to the Initial Valuation Date. We reserve the right to change the terms of, or reject any offer to purchase, the Notes prior to the Initial Valuation Date. In the event of any changes to the terms of the Notes, we will notify you and you will be asked to accept such changes in connection with your purchase. You may also choose to reject such changes in which case we may reject your offer to purchase.

●You seek an investment that provides for the full repayment of principal at maturity, and/or you are unwilling or unable to accept the risk that you may lose up to 90.00% of the principal amount of the Notes in the event that the Final Value of the Reference Asset falls below the Buffer Value.

●You anticipate that the Final Value of the Reference Asset will be less than the Buffer Value.

●You seek uncapped exposure to any positive performance of the Reference Asset.

●You do not understand and/or are unwilling or unable to accept the risks associated with an investment linked to the performance of the Reference Asset.

●You prefer the lower risk, and therefore accept the potentially lower returns, of fixed income investments with comparable maturities and credit ratings.

●You are unwilling or unable to assume our credit risk for all payments on the Notes.

●You are unwilling or unable to consent to the exercise of any U.K. Bail-in Power by any relevant U.K. resolution authority.

You should reach a decision whether to invest in the Notes after carefully considering, with your advisors, the appropriateness of the Notes in light of your investment objectives and the specific information set out in this pricing supplement and the documents referenced under “Additional Documents Related to the Offering of the Notes” in this pricing supplement. Neither the Issuer nor Barclays Capital Inc. makes any recommendation as to the appropriateness of the Notes for investment.

ADDITIONAL TERMS OF THE NOTES

The Initial Valuation Date, the Final Valuation Date and the Maturity Date are subject to postponement in certain circumstances, as described under “Reference Assets—Indices—Market Disruption Events for Securities with an Equity Index as a Reference Asset” and “Terms of the Notes—Payment Dates” in the accompanying prospectus supplement.

HYPOTHETICAL EXAMPLES OF AMOUNTS PAYABLE AT MATURITY

The following table illustrates the hypothetical payment at maturity under various circumstances. The “total return” as used in these examples, is the number, expressed as a percentage, that results from comparing the payment at maturity per $1,000 principal amount Note to $1,000. The hypothetical total returns set forth below are for illustrative purposes only and may not be the actual total returns applicable to a purchaser of the Notes. The numbers appearing in the following table and examples have been rounded for ease of analysis. The hypothetical examples below do not take into account any tax consequences from investing in the Notes and make the following key assumptions:

■Hypothetical Initial Value of the Reference Asset: 100.00*

■Hypothetical Buffer Value for the Reference Asset: 90.00 (90.00% of the hypothetical Initial Value set forth above)*

* The hypothetical Initial Value of 100.00 and the hypothetical Buffer Value of 90.00 for the Reference Asset have been chosen for illustrative purposes only and do not represent a likely Initial Value or Buffer Value for the Reference Asset. The actual Initial Value for the Reference Asset will be equal to the Closing Value on the Initial Valuation Date, and the actual Buffer Value for the Reference Asset will be equal to 90.00% of the Initial Value.

For information regarding recent values of the Reference Asset, please see “Information Regarding the Reference Asset” in this pricing supplement.

** per $1,000 principal amount Note

The following examples illustrate how the payments at maturity set forth in the table above are calculated:

Example 1: The Final Value of the Reference Asset is 105.00.

Because the Final Value of the Reference Asset is greater than or equal to the Initial Value, you will receive a payment at maturity of $1,100.00 per $1,000 principal amount Note that you hold, calculated as follows:

$1,000 + [$1,000 × lesser of (a) Reference Asset Return of the Reference Asset × Upside Leverage Factor and (b) Maximum Return]

$1,000 + [$1,000 × 5.00% × 2.00] = $1,100.00

The total return on investment of the Notes is 10.00%.

Example 2: The Final Value of the Reference Asset is 115.125.

Because the Final Value of the Reference Asset is greater than or equal to the Initial Value, you will receive a payment at maturity of $1,302.50 per $1,000 principal amount Note that you hold, calculated as follows:

PS–8

$1,000 + [$1,000 × lesser of (a) Reference Asset Return of the Reference Asset × Upside Leverage Factor and (b) Maximum Return]

$1,000 + [$1,000 × 30.25%] = $1,302.50

The total return on investment of the Notes is 30.25%, the maximum possible return on the Notes.

Example 3: The Final Value of the Reference Asset is 90.00.

Because the Final Value of the Reference Asset is less than the Initial Value, but greater than or equal to the Buffer Value, you will receive a payment at maturity of $1,000 per $1,000 principal amount Note that you hold.

The total return on investment of the Notes is 0.00%

Example 4: The Final Value of the Reference Asset is 40.00

Because the Final Value of the Reference Asset is less than the Buffer Value, you will receive a payment at maturity of $500.00 per $1,000 principal amount Note that you hold, calculated as follows:

$1,000 + [$1,000 × (Reference Asset Return of the Reference Asset + Buffer Percentage)]

$1,000 + [$1,000 × (-60.00% + 10.00%)] = $500.00

The total return on investment of the Notes is -50.00%

Example 4 demonstrates that, if the Final Value of the Reference Asset is less than the Buffer Value, you will lose 1.00% of the principal amount of your Notes for every 1.00% that the Reference Asset Return of the Reference Asset falls below -10.00%.

You may lose up to 90.00% of the principal amount of your Notes. Any payment on the Notes, including the repayment of principal, is subject to the credit risk of Barclays Bank PLC.

SELECTED RISK CONSIDERATIONS

An investment in the Notes involves significant risks. Investing in the Notes is not equivalent to investing directly in the Reference Asset or its components, if any. Some of the risks that apply to an investment in the Notes are summarized below, but we urge you to read the more detailed explanation of risks relating to the Notes generally in the “Risk Factors” section of the prospectus supplement. You should not purchase the Notes unless you understand and can bear the risks of investing in the Notes.

Risks Relating to the Notes Generally

●Your Investment in the Notes May Result in a Significant Loss — The Notes differ from ordinary debt securities in that the Issuer will not necessarily repay the full principal amount of the Notes at maturity. If the Final Value of the Reference Asset is less than the Buffer Value, you will lose 1.00% of the principal amount of your Notes for every 1.00% that the Reference Asset Return of the Reference Asset falls below -10.00%. You may lose up to 90.00% of the principal amount of your Notes.

●Potential Return Limited to the Maximum Return — If the Reference Asset Return is greater than 0.00%, you will receive a payment at maturity of $1,000 per $1,000 principal amount Note that you hold plus an additional payment that will not exceed $1,000 times the Maximum Return. Assuming the Maximum Return is set at 30.25%, the maximum payment that you may receive at maturity is $1,302.50 per $1,000 principal amount Note that you hold, and because the Upside Leverage Factor is equal to 2.00, you will not benefit from any appreciation of the Reference Asset beyond a Reference Asset Return of 15.125%, which may be significant.

●Any Payment on the Notes Will Be Determined Based on the Closing Values of the Reference Asset on the Dates Specified — Any payment on the Notes will be determined based on the Closing Values of the Reference Asset on the dates specified. You will not benefit from any more favorable values of the Reference Asset determined at any other time.

●Owning the Notes is Not the Same as Owning a Reference Asset or Any Securities to which a Reference Asset Provides Exposure — The return on the Notes may not reflect the return you would realize if you actually owned a Reference Asset or any securities to which a Reference Asset provides exposure. As a holder of the Notes, you will not have voting rights or rights to receive dividends or other distributions or any other rights that holders of a Reference Asset or any securities to which a Reference Asset provides exposure may have.

●The U.S. Federal Income Tax Consequences of an Investment in the Notes Are Uncertain — There is no direct legal authority regarding the proper U.S. federal income tax treatment of the Notes, and we do not plan to request a ruling from the Internal Revenue Service (the “IRS”). Consequently, significant aspects of the tax treatment of the Notes are uncertain, and the IRS or a court might not agree with the treatment of the Notes as prepaid forward contracts, as described below under “Tax Considerations.” If the IRS were successful in asserting an alternative treatment for the Notes, the tax consequences of the ownership and disposition of the Notes could be materially and adversely affected.

In addition, in 2007 the Treasury Department and the IRS released a notice requesting comments on various issues regarding the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. Any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the Notes, possibly with retroactive effect. You should review carefully the sections of the accompanying prospectus supplement entitled “Material U.S. Federal Income Tax Consequences—Tax Consequences to U.S. Holders—Notes Treated as Prepaid Forward or Derivative Contracts” and, if you are a non-U.S. holder, “—Tax Consequences to Non-U.S. Holders,” and consult your tax advisor regarding the U.S. federal tax consequences of an investment in the Notes (including possible alternative treatments and the issues presented by the 2007 notice), as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Risks Relating to the Issuer

●Credit of Issuer — The Notes are unsecured and unsubordinated debt obligations of the Issuer, Barclays Bank PLC, and are not, either directly or indirectly, an obligation of any third party. Any payment to be made on the Notes, including any repayment of principal, is subject to the ability of Barclays Bank PLC to satisfy its obligations as they come due and is not guaranteed by any third party. As a result, the actual and perceived creditworthiness of Barclays Bank PLC may affect the market value of the Notes, and in the event Barclays Bank PLC were to default on its obligations, you may not receive any amounts owed to you under the terms of the Notes.

●You May Lose Some or All of Your Investment If Any U.K. Bail-in Power Is Exercised by the Relevant U.K. Resolution Authority — Notwithstanding and to the exclusion of any other term of the Notes or any other agreements, arrangements or understandings between Barclays Bank PLC and any holder or beneficial owner of the Notes (or the trustee on behalf of the holders of the Notes), by acquiring the Notes, each holder or beneficial owner of the Notes acknowledges, accepts, agrees to be bound by, and consents to the exercise of, any U.K. Bail-in Power by the relevant U.K. resolution authority as set forth under “Consent to U.K. Bail-in Power” in this pricing supplement. Accordingly, any U.K. Bail-in Power may be exercised in such a manner as to result in you and other holders and beneficial owners of the Notes losing all or a part of the value of your investment in the Notes or receiving a different security from the Notes, which may be worth significantly less than the Notes and which may have significantly fewer protections than those typically afforded to debt securities. Moreover, the relevant U.K. resolution authority may exercise the U.K. Bail-in Power without providing any advance notice to, or requiring the consent of, the holders and beneficial owners of the Notes. The exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority with respect to the Notes will not be a default or an Event of Default (as each term is defined in the senior debt

PS–10

securities indenture) and the trustee will not be liable for any action that the trustee takes, or abstains from taking, in either case, in accordance with the exercise of the U.K. Bail-in Power by the relevant U.K. resolution authority with respect to the Notes. See “Consent to U.K. Bail-in Power” in this pricing supplement as well as “U.K. Bail-in Power,” “Risk Factors—Risks Relating to the Securities Generally—Regulatory action in the event a bank or investment firm in the Group is failing or likely to fail, including the exercise by the relevant U.K. resolution authority of a variety of statutory resolution powers, could materially adversely affect the value of any securities” and “Risk Factors—Risks Relating to the Securities Generally—Under the terms of the securities, you have agreed to be bound by the exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority” in the accompanying prospectus supplement.

Risks Relating to the Reference Asset

●Historical Performance of the Reference Asset Should Not Be Taken as Any Indication of the Future Performance of the Reference Asset Over the Term of the Notes — The value of the Reference Asset has fluctuated in the past and may, in the future, experience significant fluctuations. The historical performance of the Reference Asset is not an indication of the future performance of the Reference Asset over the term of the Notes. Therefore, the performance of the Reference Asset over the term of the Notes may bear no relation or resemblance to the historical performance of the Reference Asset.

●We May Accelerate the Notes If a Change-in-Law Event Occurs — Upon the occurrence of legal or regulatory changes that may, among other things, prohibit or otherwise materially restrict persons from holding the Notes or a Reference Asset or its components, or engaging in transactions in them, the Calculation Agent may determine that a change-in-law event has occurred and accelerate the Maturity Date for a payment determined by the Calculation Agent in its sole discretion. Any amount payable upon acceleration could be significantly less than any amount that would be due on the Notes if they were not accelerated. However, if the Calculation Agent elects not to accelerate the Notes, the value of, and any amount payable on, the Notes could be adversely affected, perhaps significantly, by the occurrence of those legal or regulatory changes. See “Terms of the Notes—Change-in-Law Events” in the accompanying prospectus supplement.

●The Reference Asset Reflects the Price Return of the Securities Composing the Reference Asset, Not the Total Return — The return on the Notes is based on the performance of the Reference Asset, which reflects changes in the market prices of the securities composing the Reference Asset. The Reference Asset is not a "total return" index that, in addition to reflecting those price returns, would also reflect dividends paid on the securities composing the Reference Asset. Accordingly, the return on the Notes will not include such a total return feature.

●Adjustments to the Reference Asset Could Adversely Affect the Value of the Notes — The sponsor of the Reference Asset may add, delete, substitute or adjust the securities composing the Reference Asset or make other methodological changes to the Reference Asset that could affect its value. The Calculation Agent will calculate the value to be used as the Closing Value of the Reference Asset in the event of certain material changes in or modifications to the Reference Asset. In addition, the sponsor of the Reference Asset may also discontinue or suspend calculation or publication of the Reference Asset at any time. Under these circumstances, the Calculation Agent may select a successor index that the Calculation Agent determines to be comparable to the Reference Asset or, if no successor index is available, the Calculation Agent will determine the value to be used as the Closing Value of the Reference Asset. Any of these actions could adversely affect the value of the Reference Asset and, consequently, the value of the Notes. See “Reference Assets—Indices—Adjustments Relating to Securities with an Index as a Reference Asset” in the accompanying prospectus supplement.

●The Notes Are Subject to Risks Associated with Small Capitalization Stocks — The Reference Asset tracks companies that are considered small-capitalization companies. These companies often have greater stock price volatility, lower trading volume and less liquidity than large-capitalization companies, and therefore securities linked to the Reference Asset may be more volatile than an investment linked to an index with component stocks issued by large-capitalization companies. Stock prices of small-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business and economic developments. In addition, small-capitalization companies are typically less stable financially than large-capitalization companies and may depend on a small number of key personnel, making them more vulnerable to loss of personnel. Small-capitalization companies are often subject to less analyst coverage and may be in early, and less predictable, periods of their corporate existences. Such companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and less competitive strengths than large-capitalization companies and are more susceptible to adverse developments related to their products.

Risks Relating to Conflicts of Interest

●We and Our Affiliates May Engage in Various Activities or Make Determinations That Could Materially Affect the Notes in Various Ways and Create Conflicts of Interest — We and our affiliates play a variety of roles in connection with the issuance of the Notes, as described below. In performing these roles, our and our affiliates’ economic interests are potentially adverse to your interests as an investor in the Notes.

In connection with our normal business activities and in connection with hedging our obligations under the Notes, we and our affiliates make markets in and trade various financial instruments or products for our accounts and for the account of our clients and otherwise provide investment banking and other financial services with respect to these financial instruments and products. These financial instruments and products may include securities, derivative instruments or assets that may relate to the Reference Asset or its components, if any. In any such market making, trading and hedging activity, and other financial services, we or our affiliates may take positions or take actions that are inconsistent with, or adverse to, the investment objectives of the holders of the Notes. We and our affiliates have no obligation to take the needs of any buyer, seller or holder of the Notes into

PS–11

account in conducting these activities. Such market making, trading and hedging activity, investment banking and other financial services may negatively impact the value of the Notes.

In addition, the role played by Barclays Capital Inc., as the agent for the Notes, could present significant conflicts of interest with the role of Barclays Bank PLC, as issuer of the Notes. For example, Barclays Capital Inc. or its representatives may derive compensation or financial benefit from the distribution of the Notes and such compensation or financial benefit may serve as incentive to sell the Notes instead of other investments. Furthermore, we and our affiliates establish the offering price of the Notes for initial sale to the public, and the offering price is not based upon any independent verification or valuation.

In addition to the activities described above, we will also act as the Calculation Agent for the Notes. As Calculation Agent, we will determine any values of the Reference Asset and make any other determinations necessary to calculate any payments on the Notes. In making these determinations, the Calculation Agent may be required to make discretionary judgements relating to the Reference Asset, including those described in the accompanying prospectus supplement and this pricing supplement. In making these discretionary judgments, our economic interests are potentially adverse to your interests as an investor in the Notes, and any of these determinations may adversely affect any payments on the Notes.

Risks Relating to the Estimated Value of the Notes and the Secondary Market

●The Estimated Value of Your Notes is Expected to be Lower Than the Initial Issue Price of Your Notes — The estimated value of your Notes on the Initial Valuation Date is expected to be lower, and may be significantly lower, than the initial issue price of your Notes. The difference between the initial issue price of your Notes and the estimated value of the Notes is a result of certain factors, such as any sales commissions to be paid to Barclays Capital Inc. or another affiliate of ours, any selling concessions, discounts, commissions or fees (including any structuring or other distribution related fees) to be allowed or paid to non-affiliated intermediaries, the estimated profit that we or any of our affiliates expect to earn in connection with structuring the Notes, the estimated cost which we may incur in hedging our obligations under the Notes, and estimated development and other costs which we may incur in connection with the Notes.

●The Estimated Value of Your Notes Might be Lower if Such Estimated Value Were Based on the Levels at Which Our Debt Securities Trade in the Secondary Market — The estimated value of your Notes on the Initial Valuation Date is based on a number of variables, including our internal funding rates. Our internal funding rates may vary from the levels at which our benchmark debt securities trade in the secondary market. As a result of this difference, the estimated value referenced above might be lower if such estimated value were based on the levels at which our benchmark debt securities trade in the secondary market.

●The Estimated Value of the Notes is Based on Our Internal Pricing Models, Which May Prove to be Inaccurate and May be Different from the Pricing Models of Other Financial Institutions — The estimated value of your Notes on the Initial Valuation Date is based on our internal pricing models, which take into account a number of variables and are based on a number of subjective assumptions, which may or may not materialize. These variables and assumptions are not evaluated or verified on an independent basis. Further, our pricing models may be different from other financial institutions’ pricing models and the methodologies used by us to estimate the value of the Notes may not be consistent with those of other financial institutions which may be purchasers or sellers of Notes in the secondary market. As a result, the secondary market price of your Notes may be materially different from the estimated value of the Notes determined by reference to our internal pricing models.

●The Estimated Value of Your Notes Is Not a Prediction of the Prices at Which You May Sell Your Notes in the Secondary Market, if any, and Such Secondary Market Prices, If Any, Will Likely be Lower Than the Initial Issue Price of Your Notes and May be Lower Than the Estimated Value of Your Notes — The estimated value of the Notes will not be a prediction of the prices at which Barclays Capital Inc., other affiliates of ours or third parties may be willing to purchase the Notes from you in secondary market transactions (if they are willing to purchase, which they are not obligated to do). The price at which you may be able to sell your Notes in the secondary market at any time will be influenced by many factors that cannot be predicted, such as market conditions, and any bid and ask spread for similar sized trades, and may be substantially less than our estimated value of the Notes. Further, as secondary market prices of your Notes take into account the levels at which our debt securities trade in the secondary market, and do not take into account our various costs related to the Notes such as fees, commissions, discounts, and the costs of hedging our obligations under the Notes, secondary market prices of your Notes will likely be lower than the initial issue price of your Notes. As a result, the price at which Barclays Capital Inc., other affiliates of ours or third parties may be willing to purchase the Notes from you in secondary market transactions, if any, will likely be lower than the price you paid for your Notes, and any sale prior to the Maturity Date could result in a substantial loss to you.

●The Temporary Price at Which We May Initially Buy The Notes in the Secondary Market And the Value We May Initially Use for Customer Account Statements, If We Provide Any Customer Account Statements At All, May Not Be Indicative of Future Prices of Your Notes — Assuming that all relevant factors remain constant after the Initial Valuation Date, the price at which Barclays Capital Inc. may initially buy or sell the Notes in the secondary market (if Barclays Capital Inc. makes a market in the Notes, which it is not obligated to do) and the value that we may initially use for customer account statements, if we provide any customer account statements at all, may exceed our estimated value of the Notes on the Initial Valuation Date, as well as the secondary market value of the Notes, for a temporary period after the initial Issue Date of the Notes. The price at which Barclays Capital Inc. may initially buy or sell the Notes in the secondary market and the value that we may initially use for customer account statements may not be indicative of future prices of your Notes.

PS–12

●Lack of Liquidity — The Notes will not be listed on any securities exchange. Barclays Capital Inc. and other affiliates of Barclays Bank PLC intend to make a secondary market for the Notes but are not required to do so, and may discontinue any such secondary market making at any time, without notice. Barclays Capital Inc. may at any time hold unsold inventory, which may inhibit the development of a secondary market for the Notes. 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 Barclays Capital Inc. and other affiliates of Barclays Bank PLC are willing to buy the Notes. The Notes are not designed to be short-term trading instruments. Accordingly, you should be willing and able to hold your Notes to maturity.

●Many Economic and Market Factors Will Impact the Value of the Notes — The value of the Notes will be affected by a number of economic and market factors that interact in complex and unpredictable ways and that may either offset or magnify each other, including:

othe market price of, dividend rate on and expected volatility of the Reference Asset or the components of the Reference Asset, if any;

othe time to maturity of the Notes;

ointerest and yield rates in the market generally;

oa variety of economic, financial, political, regulatory or judicial events;

osupply and demand for the Notes; and

oour creditworthiness, including actual or anticipated downgrades in our credit ratings.

TAX CONSIDERATIONS

You should review carefully the sections in the accompanying prospectus supplement entitled “Material U.S. Federal Income Tax Consequences—Tax Consequences to U.S. Holders—Notes Treated as Prepaid Forward or Derivative Contracts” and, if you are a non-U.S. holder, “—Tax Consequences to Non-U.S. Holders.” The following discussion, when read in combination with those sections, constitutes the full opinion of our special tax counsel, Davis Polk & Wardwell LLP, regarding the material U.S. federal income tax consequences of owning and disposing of the Notes.

Based on current market conditions, in the opinion of our special tax counsel, it is reasonable to treat the Notes for U.S. federal income tax purposes as prepaid forward contracts with respect to the Reference Asset. Assuming this treatment is respected, upon a sale or exchange of the Notes (including redemption at maturity), you should recognize capital gain or loss equal to the difference between the amount realized on the sale or exchange and your tax basis in the Notes, which should equal the amount you paid to acquire the Notes. This gain or loss on your Notes should be treated as long-term capital gain or loss if you hold your Notes for more than a year, whether or not you are an initial purchaser of Notes at the original issue price. However, the IRS or a court may not respect this treatment, in which case the timing and character of any income or loss on the Notes could be materially and adversely affected. In addition, in 2007 the U.S. Treasury Department and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. The notice focuses in particular on whether to require investors in these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments; the relevance of factors such as the nature of the underlying property to which the instruments are linked; the degree, if any, to which income (including any mandated accruals) realized by non-U.S. investors should be subject to withholding tax; and whether these instruments are or should be subject to the “constructive ownership” regime, which very generally can operate to recharacterize certain long-term capital gain as ordinary income and impose a notional interest charge. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the Notes, possibly with retroactive effect. You should consult your tax advisor regarding the U.S. federal income tax consequences of an investment in the Notes, including possible alternative treatments and the issues presented by this notice.

Treasury regulations under Section 871(m) generally impose a withholding tax on certain “dividend equivalents” under certain “equity linked instruments.” A recent IRS notice excludes from the scope of Section 871(m) instruments issued prior to January 1, 2027 that do not have a “delta of one” with respect to underlying securities that could pay U.S.-source dividends for U.S. federal income tax purposes (each an “Underlying Security”). Based on our determination that the Notes do not have a “delta of one” within the meaning of the regulations, we expect that these regulations will not apply to the Notes with regard to non-U.S. holders. Our determination is not binding on the IRS, and the IRS may disagree with this determination. Section 871(m) is complex and its application may depend on your particular circumstances, including whether you enter into other transactions with respect to an Underlying Security. If necessary, further information regarding the potential application of Section 871(m) will be provided in the pricing supplement for the Notes. You should consult your tax advisor regarding the potential application of Section 871(m) to the Notes.
