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 and 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, interest on, or any other amounts payable on, the Notes; (ii) the conversion of all, or a portion, of the principal amount of, 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 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 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

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 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-13 of this pricing supplement.

ADDITIONAL TERMS OF THE NOTES

The Call Valuation Dates (including the Final Valuation Date), any Call Settlement 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 Index of Equity Securities as a Reference Asset," "Reference Assets-Exchange-Traded Funds-Market Disruption Events for Securities with an Exchange-Traded Fund that Holds Equity Securities as a Reference Asset," "Reference Assets-Least or Best Performing Reference Asset-Scheduled Trading Days and Market Disruption Events for Securities Linked to the Reference Asset with the Lowest or Highest Return in a Group of Two or More Equity Securities, Exchange-Traded Funds and/or Indices of Equity Securities" and "Terms of the Notes-Payment Dates" in the accompanying prospectus supplement.

In addition, the Reference Assets and the Notes are subject to adjustment by the Calculation Agent under certain circumstances, as described under "Reference Assets-Indices-Adjustments Relating to Securities with an Index as a Reference Asset" and "Reference Assets-Exchange-Traded Funds-Adjustments Relating to Securities with an Exchange-Traded Fund as a Reference Asset" in the accompanying prospectus supplement.

HYPOTHETICAL EXAMPLES OF AMOUNTS PAYABLE UPON AUTOMATIC CALL

The following examples demonstrate the hypothetical total return upon an Automatic Call under various circumstances. The "total return" as used in these examples is the number, expressed as a percentage, that results from comparing the aggregate payments 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 tables 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.

Example 1: The Notes are redeemed on the first Call Valuation Date.

Because the Closing Value of each Reference Asset on the first Call Valuation Date is greater than or equal to its Call Value, the Notes are redeemed and you will receive the Redemption Price on the related Call Settlement Date.

The Call Premium with respect to the first Call Valuation Date is calculated as follows:

Call Premium = (a) Periodic Call Premium multiplied by (b) n:

$135.00 × 0.25 = $33.75

Accordingly, the Redemption Price with respect to the first Call Valuation Date is $1,033.75 per $1,000 principal amount of the Notes, as shown in the table above. The Notes will cease to be outstanding after the Call Settlement Date, and you will not receive any further payments on the Notes.

The total return on investment of the Notes is 3.375%.

Example 2: The Notes are redeemed on the third Call Valuation Date.

Because the Closing Value of each Reference Asset on the third Call Valuation Date is greater than or equal to its Call Value, the Notes are redeemed and you will receive the Redemption Price on the related Call Settlement Date.

The Call Premium with respect to the third Call Valuation Date is calculated as follows:

Call Premium = (a) Periodic Call Premium multiplied by (b) n:

$135.00 × 0.41667 = $56.25

Accordingly, the Redemption Price with respect to the third Call Valuation Date is $1,056.25 per $1,000 principal amount of the Notes, as shown in the table above. The Notes will cease to be outstanding after the Call Settlement Date, and you will not receive any further payments on the Notes.

The total return on investment of the Notes is 5.625%.

Example 3: The Notes are redeemed on the final Call Valuation Date.

PS-9

Because the Closing Value of each Reference Asset on the final Call Valuation Date is greater than or equal to its Call Value, the Notes are redeemed and you will receive the Redemption Price on the related Call Settlement Date.

The Call Premium with respect to the final Call Valuation Date is calculated as follows:

Call Premium = (a) Periodic Call Premium multiplied by (b) n:

$135.00 × 1.75 = $236.25

Accordingly, the Redemption Price with respect to the final Call Valuation Date is $1,236.25 per $1,000 principal amount of the Notes, as shown in the table above. The Notes will cease to be outstanding after the Call Settlement Date, and you will not receive any further payments on the Notes.

The total return on investment of the Notes is 23.625%.

PS-10

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:

* Thehypothetical Initial Value of 100.00 and thehypothetical Barrier Value of 70.00 for each Reference Asset have been chosen for illustrative purposes only. The actual Initial Value and Barrier Value for each Reference Asset are as set forth on the cover of 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 Reference Asset A is 135.00, the Final Value of Reference Asset B is 130.00 and the Final Value of Reference Asset C is $140.00.

Because Reference Asset B has the lowest Reference Asset Return, Reference Asset B is the Least Performing Reference Asset. Because the Final Value of the Least Performing Reference Asset is greater than or equal to its Call Value, the Notes are subject to an Automatic Call. Accordingly, you will receive on the Maturity Date the applicable Redemption Price of $1,236.25 per $1,000 principal amount Note that you hold.

The total return on investment of the Notes is 23.62%, the maximum possible return on the Notes.

Example 2: The Final Value of Reference Asset A is 140.00, the Final Value of Reference Asset B is 90.00 and the Final Value of Reference Asset C is $105.00.

Because Reference Asset B has the lowest Reference Asset Return, Reference Asset B is the Least Performing Reference Asset. Because the Final Value of the Least Performing Reference Asset is less than its Call Value, the Notes are not subject to an Automatic Call.

PS-11

Because the Final Value of the Least Performing Reference Asset is less than its Call Value, but greater than or equal to its Barrier 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 3: The Final Value of Reference Asset A is 60.00, the Final Value of Reference Asset B is 120.00 and the Final Value of Reference Asset C is $100.00.

Because Reference Asset A has the lowest Reference Asset Return, Reference Asset A is the Least Performing Reference Asset. Because the Final Value of the Least Performing Reference Asset is less than its Call Value, the Notes are not subject to an Automatic Call. Because the Final Value of the Least Performing Reference Asset is less than its Barrier Value, you will receive a payment at maturity of $600.00 per $1,000 principal amount Note that you hold, calculated as follows:

$1,000 + [$1,000 × Reference Asset Return of the Least Performing Reference Asset]

$1,000 + [$1,000 × -40.00%] = $600.00

The total return on investment of the Notes is -40.00%.

Example 3 demonstrates that if the Notes are not redeemed prior to scheduled maturity, and if the Final Value of the Least Performing Reference Asset is less than its Barrier Value, your investment in the Notes will be fully exposed to the decline of the Least Performing Reference Asset from its Initial Value. You will not benefit in any way from the Reference Asset Return of any other Reference Asset being higher than the Reference Asset Return of the Least Performing Reference Asset.

If the Notes are not redeemed prior to scheduled maturity, you may lose up to 100.00% 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.

PS-12

SELECTED RISK CONSIDERATIONS

An investment in the Notes involves significant risks. Investing in the Notes is not equivalent to investing directly in the Reference Assets or their 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

The Redemption Price that you would receive on a Call Settlement Date may be less than the aggregate amount of payments that you would have received had the Notes not been redeemed. There is no guarantee that you would be able to reinvest the proceeds from an investment in the Notes in a comparable investment with a similar level of risk in the event the Notes are redeemed prior to the Maturity Date. No additional payments will be due after the relevant Call Settlement Date. The fact that the Notes may be redeemed prior to maturity may also adversely impact your ability to sell your Notes and the price at which they may be sold.

PS-13

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

Risks Relating to the Reference Assets

PS-14

Generally, the longer the time remaining to maturity, the more the market price of the Notes will be affected by the factors described above. In addition, the XLK Fund may diverge significantly from the performance of its Underlying Index due to differences in trading hours between the XLK Fund and the securities composing its Underlying Index or other circumstances. During periods of market volatility, the component securities held by the XLK Fund may be unavailable in the secondary market, market participants may be unable to calculate accurately the intraday net asset value per share of the XLK Fund and the liquidity of the XLK Fund may be adversely affected. This kind of market volatility may also disrupt the ability of market participants to create and redeem shares in the XLK Fund. Further, market volatility may adversely affect, sometimes materially, the prices at which market participants are willing to buy and sell shares of the XLK Fund. As a result, under these circumstances, the market value of the XLK Fund may vary substantially from the net asset value per share of the XLK Fund. Because the Notes are linked to the performance of the XLK Fund and not its Underlying Index, the return on your Notes may be less than that of an alternative investment linked directly to its Underlying Index.

PS-15

Risks Relating to Conflicts of Interest

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 Assets or their 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 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 Assets 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 Assets, including determining whether a market disruption event has occurred or whether certain adjustments to the Reference Assets or other terms of the Notes are necessary, as further described in the accompanying prospectus 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.

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. The following discussion supersedes the discussion in the accompanying prospectus supplement to the extent it is inconsistent therewith.

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 Assets. Assuming this treatment is respected, upon a sale or exchange of the Notes (including redemption upon an automatic call or 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 short-term capital gain or loss unless you hold your Notes for more than a year, in which case the gain or loss should be long-term capital gain or loss, 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, our special tax counsel is of the opinion that these regulations should 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. You should consult your tax advisor regarding the potential application of Section 871(m) to the Notes.

PS-21

SUPPLEMENTAL PLAN OF DISTRIBUTION

We have agreed to sell to Barclays Capital Inc. (the "Agent"), and the Agent has agreed to purchase from us, the principal amount of the Notes, and at the price, specified on the cover of this pricing supplement. The Agent commits to take and pay for all of the Notes, if any are taken.

We expect that delivery of the Notes will be made against payment for the Notes on the Issue Date, which is more than one business day following the Initial Valuation Date. Notwithstanding anything to the contrary in the accompanying prospectus supplement, under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes on any date prior to one business day before delivery will be required to specify alternative settlement arrangements to prevent a failed settlement and should consult their own advisor.

VALIDITY OF THE NOTES

In the opinion of Davis Polk & Wardwell LLP, as special United States products counsel to Barclays Bank PLC, when the Notes offered by this pricing supplement have been executed and issued by Barclays Bank PLC and authenticated by the trustee pursuant to the indenture, and delivered against payment as contemplated herein, such Notes will be valid and binding obligations of Barclays Bank PLC, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors' rights generally, concepts of reasonableness and equitable principles of general applicability (including, without limitation, concepts of good faith, fair dealing and the lack of bad faith) and possible judicial or regulatory actions or application giving effect to governmental actions or foreign laws affecting creditors' rights, provided that such counsel expresses no opinion as to the effect of fraudulent conveyance, fraudulent transfer or similar provision of applicable law on the conclusions expressed above. This opinion is given as of the date hereof and is limited to the laws of the State of New York. Insofar as this opinion involves matters governed by English law, Davis Polk & Wardwell LLP has relied, with Barclays Bank PLC's permission, on the opinion of Davis Polk & Wardwell London LLP, dated as of July 12, 2024, filed as an exhibit to a report on Form 6-K by Barclays Bank PLC on July 12, 2024, and this opinion is subject to the same assumptions, qualifications and limitations as set forth in such opinion of Davis Polk & Wardwell London LLP. In addition, this opinion is subject to customary assumptions about the trustee's authorization, execution and delivery of the indenture and its authentication of the Notes and the validity, binding nature and enforceability of the indenture with respect to the trustee, all as stated in the opinion of Davis Polk & Wardwell LLP, dated July 12, 2024, which has been filed as an exhibit to the report on Form 6-K referred to above.
