Principal at Risk Securities

Unlike conventional debt securities, the securities do not guarantee the payment of interest or any return of principal at maturity. Instead, the securities offer the opportunity for investors to receive on the related contingent payment date a contingent quarterly payment equal to at least 6.725% of the stated principal amount (the actual contingent quarterly payment will be determined on the pricing date), plus all previously unpaid contingent quarterly payments, if any, if on any determination date the closing price of the underlier is greater than or equal to 65% of the initial underlier value, which we refer to as the downside threshold level. If the closing price of the underlier is greater than or equal to the initial underlier value on any determination date (other than the final determination date), the securities will be automatically redeemed for an amount per security equal to the stated principal amount plus the contingent quarterly payment and any unpaid contingent quarterly payments otherwise due. However, if on any determination date the closing price of the underlier is less than the initial underlier value, the securities will not be redeemed and if that closing price is less than the downside threshold level, investors will not receive the contingent quarterly payment applicable to that determination date on the related contingent payment date. If the securities are not redeemed prior to maturity and the final underlier value is greater than or equal to the downside threshold level, the payment at maturity due on the securities will be equal to the stated principal amount plus the contingent quarterly payment and any unpaid contingent quarterly payments otherwise due. However, if the securities are not redeemed prior to maturity and the final underlier value is less than the downside threshold level, at maturity investors will lose 1% of the stated principal amount for every 1% that the final underlier value is less than the initial underlier value. Under these circumstances, the amount investors receive will be less than 65% of the stated principal amount and could be zero. The securities are for investors who are willing and able to risk their principal and forgo guaranteed interest payments, in exchange for the opportunity to potentially receive contingent quarterly payments at an above-market rate, subject to automatic early redemption. Investors will not participate in any appreciation of the underlier even though investors will be exposed to the depreciation in the value of the underlier if the securities have not been redeemed prior to maturity and the final underlier value is less than the downside threshold level. Investors may lose their entire initial investment in the securities. The securities are unsecured and unsubordinated debt obligations of Barclays Bank PLC. Any payment on the securities, including any repayment of principal, is subject to the creditworthiness of Barclays Bank PLC and is not guaranteed by any third party. If Barclays Bank PLC were to default on its payment obligations or become subject to the exercise of any U.K. Bail-in Power (as described on page 5 of this document) by the relevant U.K. resolution authority, you might not receive any amounts owed to you under the securities. See “Risk Factors” and “Consent to U.K. Bail-in Power” in this document and “Risk Factors” in the accompanying prospectus supplement.

SUMMARY TERMS
Issuer:	Barclays Bank PLC
Reference asset*:	Rivian Automotive, Inc. Class A common stock (Bloomberg ticker symbol “RIVN UW<Equity>”) (the “underlier”)
Aggregate principal amount:	$
Stated principal amount:	$1,000 per security
Pricing date†:	December 21, 2023
Original issue date†:	December 27, 2023
Maturity date*†:	December 24, 2026
Automatic early redemption:	If, on any determination date (other than the final determination date), the closing price of the underlier is greater than or equal to the initial underlier value, the securities will be automatically redeemed for an early redemption payment on the contingent payment date immediately following that determination date. The securities will not be redeemed early if the closing price of the underlier is less than the initial underlier value on the related determination date. No further payments will be made on the securities after they have been redeemed.
Early redemption payment:	The early redemption payment will be an amount per security equal to (i) the stated principal amount plus (ii) the contingent quarterly payment and any unpaid contingent quarterly payments otherwise due.
Contingent quarterly payment:	· If, on any determination date, the closing price of the underlier is greater than or equal to the downside threshold level, we will pay on the related contingent payment date a contingent quarterly payment of at least $67.25 (at least 6.725% of the stated principal amount) per security, plus the amounts of all contingent quarterly payments, if any, that would have been paid on a previous contingent payment date had the closing price of the underlier been greater than or equal to the downside threshold level on the related determination date and that have not been previously paid (“unpaid contingent quarterly payments”). The actual contingent quarterly payment will be determined on the pricing date. · If, on any determination date, the closing price of the underlier is less than the downside threshold level, the contingent quarterly payment applicable to that determination date will not be payable on the related contingent payment date. The closing price of the underlier could be below the downside threshold level on most or all of the determination dates so that you receive few or no contingent quarterly payments over the term of the securities.
Payment at maturity:	If the securities are not redeemed prior to maturity, you will receive on the maturity date a cash payment per security determined as follows: · If the final underlier value is greater than or equal to the downside threshold level: (i) stated principal amount plus (ii) the contingent quarterly payment and any unpaid contingent quarterly payments otherwise due · If the final underlier value is less than the downside threshold level: stated principal amount × underlier performance factor Under these circumstances, the payment at maturity will be less than the stated principal amount of $1,000 and will represent a loss of more than 35%, and possibly all, of an investor’s principal amount. Investors may lose their entire initial investment in the securities. Any payment on the securities, including any repayment of principal, is not guaranteed by any third party and is subject to (a) the creditworthiness of Barclays Bank PLC and (b) the risk of exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority.
U.K. Bail-in Power acknowledgment:	Notwithstanding and to the exclusion of any other term of the securities or any other agreements, arrangements or understandings between Barclays Bank PLC and any holder or beneficial owner of the securities (or the trustee on behalf of the holders of the securities), by acquiring the securities, each holder and beneficial owner of the securities 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. See “Consent to U.K. Bail-in Power” on page 5 of this document.

Accordingly, the total principal amount of the securities may include a portion that was not purchased by investors on the original issue date.

Additional Information Regarding Our Estimated Value of the Securities

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 pricing date is based on our internal funding rates. Our estimated value of the securities might 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 securities on the pricing date is expected to be less than the initial issue price of the securities. The difference between the initial issue price of the securities and our estimated value of the securities is expected to result from several factors, including any sales commissions expected to be paid to Barclays Capital Inc. or another affiliate of ours, any selling concessions, discounts, commissions or fees expected 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 securities, the estimated cost that we may incur in hedging our obligations under the securities, and estimated development and other costs that we may incur in connection with the securities. These other costs will include a fee paid to LFT Securities, LLC, an entity in which an affiliate of Morgan Stanley Wealth Management has an ownership interest, for providing certain electronic platform services with respect to this offering.

Our estimated value on the pricing date is not a prediction of the price at which the securities may trade in the secondary market, nor will it be the price at which Barclays Capital Inc. may buy or sell the securities 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 securities in the secondary market but it is not obligated to do so.

Assuming that all relevant factors remain constant after the pricing date, the price at which Barclays Capital Inc. may initially buy or sell the securities 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 pricing date for a temporary period expected to be approximately 40 days after the initial issue date of the securities because, in our discretion, we may elect to effectively reimburse to investors a portion of the estimated cost of hedging our obligations under the securities and other costs in connection with the securities that we will no longer expect to incur over the term of the securities. 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 securities and/or any agreement we may have with the distributors of the securities. The amount of our estimated costs that 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 securities based on changes in market conditions and other factors that cannot be predicted.

We urge you to read “Risk Factors” beginning on page 12 of this document.

You may revoke your offer to purchase the securities at any time prior to the pricing date. We reserve the right to change the terms of, or reject any offer to purchase, the securities prior to their pricing date. In the event of any changes to the terms of the securities, 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.

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 securities; (ii) the conversion of all, or a portion, of the principal amount of, interest on, or any other amounts payable on, the securities 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 securities such shares, securities or obligations); (iii) the cancellation of the securities and/or (iv) the amendment or alteration of the maturity of the securities, or amendment of the amount of interest or any other amounts due on the securities, 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 securities 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 securities further acknowledges and agrees that the rights of the holders or beneficial owners of the securities 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 securities 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 “Risk Factors—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 document 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.

Investment Summary

Contingent Income Auto-Callable Securities

Principal at Risk Securities

The Contingent Income Auto-Callable Securities due December 24, 2026 Based on the Performance of the Class A Common Stock of Rivian Automotive, Inc., which we refer to as the securities, provide an opportunity for investors to receive on the related contingent payment date a contingent quarterly payment, which is an amount equal to at least $67.25 (at least 6.725% of the stated principal amount), plus all previously unpaid contingent quarterly payments, if any, if on any determination date the closing price of the underlier is greater than or equal to 65% of the initial underlier value, which we refer to as the downside threshold level. However, if the closing price of the underlier is less than the downside threshold level on a determination date, investors will not receive the contingent quarterly payment applicable to that determination date on the related contingent payment date. The actual contingent quarterly payment will be determined on the pricing date. The closing price of the underlier could be below the downside threshold level on most or all of the determination dates so that you receive few or no contingent quarterly payments over the term of the securities.

If the closing price of the underlier is greater than or equal to the initial underlier value on any determination date (other than the final determination date), the securities will be automatically redeemed for an early redemption payment equal to the stated principal amount plus the contingent quarterly payment and any unpaid contingent quarterly payments otherwise due. If the securities are automatically redeemed prior to maturity, investors will receive no further contingent quarterly payments. At maturity, if the securities have not previously been redeemed and the final underlier value is greater than or equal to the downside threshold level, the payment at maturity will be equal to the stated principal amount plus the contingent quarterly payment and any unpaid contingent quarterly payments otherwise due. However, if the securities have not previously been redeemed and the final underlier value is less than the downside threshold level, investors will lose 1% of the stated principal amount for every 1% that the final underlier value is less than the initial underlier value. Under these circumstances, the amount investors receive will be less than 65% of the stated principal amount and could be zero. Investors in the securities must be willing and able to accept the risk of losing their entire initial investment and also the risk of not receiving any contingent quarterly payment throughout the entire term of the securities. In addition, investors will not participate in any appreciation of the underlier.

Key Investment Rationale

The securities are for investors who are willing and able to risk their principal and forgo guaranteed interest payments, in exchange for the opportunity to potentially receive contingent quarterly payments at an above-market rate, subject to automatic early redemption. The securities offer investors an opportunity to receive on the related contingent payment date a contingent quarterly payment of at least $67.25 (at least 6.725% of the stated principal amount), plus all previously unpaid contingent quarterly payments, if any, if on any determination date the closing price of the underlier is greater than or equal to the downside threshold level. The actual contingent quarterly payment will be determined on the pricing date. In addition, the following scenarios reflect the potential payment on the securities, if any, upon an automatic early redemption or at maturity:

Scenario 1	On any determination date (other than the final determination date), the closing price of the underlier is greater than or equal to the initial underlier value. § The securities will be automatically redeemed for (i) the stated principal amount plus (ii) the contingent quarterly payment and any unpaid contingent quarterly payments otherwise due. § Investors will not participate in any appreciation of the underlier from the initial underlier value and will receive no further contingent quarterly payments.
Scenario 2	The securities are not automatically redeemed prior to maturity and the final underlier value is greater than or equal to the downside threshold level. § The payment due at maturity will be (i) the stated principal amount plus (ii) the contingent quarterly payment and any unpaid contingent quarterly payments otherwise due. § Investors will not participate in any appreciation of the underlier from the initial underlier value.
Scenario 3	The securities are not automatically redeemed prior to maturity and the final underlier value is less than the downside threshold level. § The payment due at maturity will be equal to the stated principal amount times the underlier performance factor. In this case, at maturity, the securities pay less than 65% of the stated principal amount and the percentage loss of the stated principal amount will be equal to the percentage decrease in the final underlier value from the initial underlier value. For example, if the final underlier value is 55% less than the initial underlier value, the securities will pay $450.00 per security, or 45% of the stated principal amount, for a loss of 55% of the stated principal amount. Investors will lose a significant portion and may lose all of their principal in this scenario.

Hypothetical Examples

The numbers appearing in the following examples may have been rounded for ease of analysis. The examples below assume that the securities will be held until maturity or earlier redemption and do not take into account the tax consequences of an investment in the securities. The examples below are based on the following terms:*

Hypothetical Initial Underlier Value:	$100.00
Hypothetical Downside Threshold Level:	$65.000, which is 65% of the hypothetical initial underlier value
Hypothetical Contingent Quarterly Payment:	$67.25 (6.725% of the stated principal amount). The actual contingent quarterly payment will be set on the pricing date and will be at least 6.725% of the stated principal amount.
Stated Principal Amount:	$1,000 per security

* Terms used for purposes of these hypothetical examples may not represent the actual initial underlier value, downside threshold level or contingent quarterly payment applicable to the securities. In particular, the hypothetical initial underlier value of $100.00 used in these examples has been chosen for illustrative purposes only and may not represent a likely actual initial underlier value. Please see “Rivian Automotive, Inc. Overview” below for recent actual values of the underlier. The actual initial underlier value, downside threshold level and contingent quarterly payment applicable to the securities will be determined on the pricing date.

In Examples 1 and 2, the closing price of the underlier is greater than or equal to the hypothetical initial underlier value of $100.00 on one of the determination dates prior to the final determination date (the actual initial underlier value will be determined on the pricing date). Because the closing price of the underlier is greater than or equal to the initial underlier value on one of the determination dates prior to the final determination date, the securities are automatically redeemed following the relevant determination date. In Examples 3 and 4, the closing price of the underlier on the determination dates prior to the final determination date is less than the initial underlier value, and, consequently, the securities are not automatically redeemed prior to, and remain outstanding until, maturity.

In Example 1, the securities are automatically redeemed following the second determination date, as the closing price of the underlier on the second determination date is greater than or equal to the initial underlier value. Because the closing price of the underlier is less than the downside threshold level on the first determination date, you will not receive the contingent quarterly payment applicable to that determination date on the related contingent payment date. Following the second determination date, you receive the stated principal amount plus the contingent quarterly payment and the unpaid contingent quarterly payment otherwise due. Accordingly, the contingent quarterly payment that would have been paid on the first contingent payment date had the closing price of the underlier been greater than or equal to the downside threshold level on that determination date will be paid following the second determination date. You will receive the early redemption payment, calculated as follows:

stated principal amount + contingent quarterly payment + unpaid contingent quarterly payment(s)
= $1,000 + $67.25 + ($67.25 × 1) = $1,134.50

In this example, the automatic early redemption feature limits the term of your investment to approximately 6 months and you may not be able to reinvest at comparable terms or returns. If the securities are redeemed early, you will stop receiving contingent quarterly payments.

In Example 2, the securities are automatically redeemed following the fifth determination date, as the closing price of the underlier on the fifth determination date is greater than the initial underlier value. As the closing price of the underlier on the first determination date is greater than or equal to the downside threshold level, you receive the contingent quarterly payment of $67.25 with respect to that determination date. Because the closing price of the underlier is less than the downside threshold level on the second and third determination dates, you will not receive the contingent quarterly payments applicable to those determination dates on the related contingent payment dates; however, because the closing price of the underlier on the fourth determination date is greater than or equal to the downside threshold level, the contingent quarterly payments that would have been paid on the second and third contingent payment dates had the closing price of the underlier been greater than or equal to the downside threshold level on those determination dates will be paid on the fourth contingent payment date. Following the fifth determination date, you receive an early redemption payment of $1,067.25, which includes the contingent quarterly payment with respect to that determination date.

In this example, the automatic early redemption feature limits the term of your investment to approximately 15 months and you may not be able to reinvest at comparable terms or returns. If the securities are redeemed early, you will stop receiving contingent quarterly payments. Further, although the underlier has appreciated by 25% from the initial underlier value on the fifth determination date, upon automatic early redemption, you receive only $1,067.25 per security and do not benefit from such appreciation.

Examples 3 and 4 illustrate the payment at maturity per security based on the final underlier value.

In Example 3, the closing price of the underlier is below the downside threshold level on each determination date throughout the term of the securities. As a result, you do not receive any contingent quarterly payments during the term of the securities. In addition, because the final underlier value is less than the downside threshold level, at maturity, your initial investment is fully exposed to the decline in the closing price of the underlier. Thus, investors will receive a cash payment at maturity that is significantly less than the stated principal amount, calculated as follows:

$1,000 × underlier performance factor

= $1,000 × (final underlier value / initial underlier value)

= $1,000 × ($40.00 / $100.00)

= $400.00

In this example, the cash payment you receive at maturity is significantly less than the stated principal amount.

In Example 4, as the closing price of the underlier on the first determination date is greater than or equal to the downside threshold level, you receive the contingent quarterly payment of $67.25 with respect to that determination date. Because the closing price of the underlier is less than the downside threshold level on the second through eleventh determination dates, you will not receive the contingent quarterly payments applicable to those determination dates on the related contingent payment dates. In addition, the closing price of the underlier decreases to a final underlier value of $75.00. Although the final underlier value is less than the initial underlier value, because the final underlier value is still not less than the downside threshold level, you receive the stated principal amount plus the contingent quarterly payment and the unpaid contingent quarterly payments otherwise due. Accordingly, the contingent quarterly payments that would have been paid on the second through eleventh contingent payment dates had the closing price of the underlier been greater than or equal to the downside threshold level on those determination dates will be paid on the maturity date. Your payment at maturity is calculated as follows:

stated principal amount + contingent quarterly payment + unpaid contingent quarterly payment(s)
= $1,000 + $67.25 + ($67.25 × 10) = $1,739.75

In this example, although the final underlier value represents a decline of 25% from the initial underlier value, you receive the stated principal amount plus the contingent quarterly payment and any unpaid contingent quarterly payments otherwise due, equal to a total payment of $1,739.75 per security at maturity.

Risk Factors

An investment in the securities involves significant risks. We urge you to consult your investment, legal, tax, accounting and other advisors before you invest in the securities. Investing in the securities is not equivalent to investing directly in the underlier. 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 risks relating to the securities generally in the “Risk Factors” section of the prospectus supplement. You should not purchase the securities unless you understand and can bear the risks of investing in the securities.

Risks Relating to the Securities Generally

§ The securities do not guarantee the return of any principal. The terms of the securities differ from those of ordinary debt securities in that the securities do not guarantee the return of any of the stated principal amount at maturity. Instead, if the securities have not been automatically redeemed prior to maturity and if the final underlier value is less than the downside threshold level, you will be exposed to the decline in the closing price of the underlier, as compared to the initial underlier value, on a 1-to-1 basis and you will receive for each security that you hold at maturity an amount in cash equal to the stated principal amount times the underlier performance factor. Under these circumstances, your payment at maturity will be less than 65% of the stated principal amount and could be zero.

§ You may not receive some or all of the contingent quarterly payments. The securities differ from ordinary debt securities in that they do not provide for regular interest payments. Instead, a contingent quarterly payment, plus all previously unpaid contingent quarterly payments, if any, will be payable on the related contingent payment date if on any determination date the closing price of the underlier is greater than or equal to the downside threshold level. If the closing price of the underlier is less than the downside threshold level on any determination date, we will not pay the contingent quarterly payment applicable to that determination date or any unpaid contingent quarterly payments on the related contingent payment date. If a contingent quarterly payment is not paid on any contingent payment date, that contingent quarterly payment will be paid as an unpaid contingent quarterly payment on a later contingent payment date only if the closing price of the underlier on a subsequent determination date is greater than or equal to the downside threshold level. The closing price of the underlier could be below the downside threshold level on most or all of the determination dates so that you receive few or no contingent quarterly payments over the term of the securities. If you do not receive sufficient contingent quarterly payments over the term of the securities, the overall return on the securities may be less than the amount that would be paid on a conventional debt security of the issuer of comparable maturity.

§ Your potential return on the securities will be different depending on the sequence of closing prices on the determination dates. Depending on the sequence in which the closing price of the underlier is greater than or equal to the downside threshold level on specific determination dates (if at all), you could receive a lesser or greater return, regardless of the number of determination dates on which the closing price of the underlier is greater than or equal to the downside threshold level. For example, if the closing price of the underlier is less than the downside threshold level on each of the first eleven determination dates but is greater than or equal to the downside threshold level on the final determination date, you will receive twelve contingent quarterly payments (eleven in the form of unpaid contingent quarterly payments). However, if the closing price of the underlier is greater than or equal to the downside threshold level on each of the first two determination dates but on no subsequent determination dates, you will receive only two contingent quarterly payments, even though the closing price of the underlier was greater than or equal to the downside threshold level on twice as many determination dates than in the previous example.

§ You will not participate in any appreciation in the value of the underlier. You will not participate in any appreciation in the value of the underlier from the initial underlier value even though you will be exposed to the depreciation in the value of the underlier if the securities have not been redeemed prior to maturity and the final underlier value is less than the downside threshold level. The return on the securities will be limited to any contingent quarterly payments that are paid on the securities.

§ Automatic early redemption risk. The term of your investment in the securities may be limited to as short as approximately three months by the automatic early redemption feature of the securities. If the securities are redeemed prior to maturity, no further contingent quarterly payments will be made on the securities and you may be forced to reinvest in a lower interest rate environment. There is no guarantee that you would be able to reinvest the proceeds from an investment in the securities in a comparable investment with a similar level of risk in the event the securities are redeemed prior to the maturity date.

§ Any payment on the securities will be determined based on the closing prices of the underlier on the dates specified. Any payment on the securities will be determined based on the closing prices of the underlier on the dates specified. You will not benefit from any more favorable value of the underlier determined at any other time.

§ Contingent repayment of principal applies only at maturity or upon any automatic early redemption. You should be willing and able to hold the securities to maturity or any automatic early redemption. If you sell the securities prior to maturity in the secondary market, if any, you may have to sell the securities at a loss relative to your initial investment even if the price of the underlier is above the downside threshold level.

§ The securities are subject to volatility risk. Volatility is a measure of the degree of variation in the price of the underlier over a period of time. The contingent quarterly payment is determined based on a number of factors, including the expected volatility of the underlier. The contingent quarterly payment is higher than the fixed rate that we would pay on a conventional

December 2023 Page 12

Contingent Income Auto-Callable Securities due December 24, 2026

Based on the Performance of the Class A Common Stock of Rivian Automotive, Inc.

Principal at Risk Securities

debt security of the same tenor and is higher than it otherwise would be if the level of expected volatility of the underlier taken into account in determining the terms of the securities were lower. As volatility of the underlier increases, there will typically be a greater likelihood that (a) the closing price of the underlier will be less than the downside threshold level on one or more determination dates and (b) the final underlier value will be less than the downside threshold level.

Accordingly, you should understand that a higher contingent quarterly payment reflects, among other things, an indication of a greater likelihood that you will (a) not receive contingent quarterly payments with respect to one or more determination dates and/or (b) incur a loss of principal at maturity than would have been the case had the contingent quarterly payment been lower. In addition, actual volatility over the term of the securities may be significantly higher than the expected volatility at the time the terms of the securities were determined. If actual volatility is higher than expected, you will face an even greater risk that you will not receive contingent quarterly payments and/or that you will lose a significant portion or all of your principal at maturity for the reasons described above.

§ Investing in the securities is not equivalent to investing in the underlier. Investors in the securities will not own the underlier or have voting rights or rights to receive dividends or other distributions or any other rights with respect to the underlier.

§ Tax treatment. Significant aspects of the tax treatment of the securities are uncertain. You should consult your tax advisor about your tax situation. See “Additional provisions—Tax considerations” below.

Risks Relating to the Issuer

§ Credit of issuer. The securities 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 securities, 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 securities and, in the event Barclays Bank PLC were to default on its obligations, you might not receive any amount owed to you under the terms of the securities.

§ 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 securities or any other agreements, arrangements or understandings between Barclays Bank PLC and any holder or beneficial owner of the securities (or the trustee on behalf of the holders of the securities), by acquiring the securities, each holder and beneficial owner of the securities 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 document. 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 securities losing all or a part of the value of your investment in the securities or receiving a different security from the securities, which may be worth significantly less than the securities 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 securities. The exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority with respect to the securities will not be a default or an Event of Default (as each term is defined in the senior debt 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 securities. See “Consent to U.K. Bail-in Power” in this document 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 Underlier

§ No affiliation with the issuer of the underlier. The issuer of the underlier is not an affiliate of ours, is not involved with this offering in any way, and has no obligation to consider your interests in taking any corporate actions that might affect the value of the securities. We have not made any due diligence inquiry with respect to the issuer of the underlier in connection with this offering.

§ Single equity risk. The price of the underlier can rise or fall sharply due to factors specific to the underlier and its issuer, such as stock price volatility, earnings, financial conditions, corporate, industry and regulatory developments, management changes and decisions and other events, as well as general market factors, such as general stock market volatility and levels, interest rates and economic and political conditions. We urge you to review financial and other information filed periodically with the SEC by the issuer of the underlier.

§ The underlier has a limited trading history. The underlier commenced regular trading on The Nasdaq Stock Market on November 10, 2021 and therefore has limited historical performance. Past performance should not be considered indicative of future performance.

December 2023 Page 13

Based on the Performance of the Class A Common Stock of Rivian Automotive, Inc.

Principal at Risk Securities

§ Anti-dilution protection is limited, and the calculation agent has discretion to make anti-dilution adjustments. The calculation agent may in its sole discretion make adjustments affecting the amounts payable on the securities upon the occurrence of certain corporate events (such as stock splits or extraordinary or special dividends) that the calculation agent determines have a diluting or concentrative effect on the theoretical value of the underlier. However, the calculation agent might not make such adjustments in response to all events that could affect the underlier. The occurrence of any such event and any adjustment made by the calculation agent (or a determination by the calculation agent not to make any adjustment) may adversely affect the market price of, and any amounts payable on, the securities. See “Reference Assets—Equity Securities—Share Adjustments Relating to Securities with an Equity Security as a Reference Asset” in the accompanying prospectus supplement.

§ Reorganization or other events could adversely affect the value of the securities or result in the securities being accelerated. Upon the occurrence of certain reorganization events or a nationalization, expropriation, liquidation, bankruptcy, insolvency or de-listing of the underlier, the calculation agent will make adjustments to the underlier that may result in payments on the securities being based on the performance of shares, cash or other assets distributed to holders of the underlier upon the occurrence of such event or, in some cases, the calculation agent may accelerate the maturity date for a payment determined by the calculation agent. Any of these actions could adversely affect the value of the underlier and, consequently, the value of the securities. Any amount payable upon acceleration could be significantly less than the amount(s) that would be due on the securities if they were not accelerated. However, if we elect not to accelerate the securities, the value of, and any amount payable on, the securities could be adversely affected, perhaps significantly. See “Reference Assets—Equity Securities—Share Adjustments Relating to Securities with an Equity Security as a Reference Asset” in the accompanying prospectus supplement.

§ Governmental legislative or regulatory actions, such as sanctions, could adversely affect your investment in the securities. Governmental legislative or regulatory actions, including, without limitation, sanctions-related actions by the U.S. or a foreign government, could prohibit or otherwise restrict persons from holding the securities or the underlier, or engaging in transactions in them, and any such action could adversely affect the value of the underlier. These legislative or regulatory actions could result in restrictions on the securities or the de-listing of the underlier. You may lose a significant portion or all of your initial investment in the securities if the underlier is de-listed or if you are forced to divest the securities due to government mandates, especially if such de-listing occurs or such divestment must be made at a time when the value of the securities has declined. See “—Reorganization or other events could adversely affect the value of the securities or result in the securities being accelerated” above.

Risks Relating to Conflicts of Interest

§ We may engage in business with or involving the issuer of the underlier without regard to your interests. We or our affiliates may presently or from time to time engage in business with the issuer of the underlier without regard to your interests and thus may acquire non-public information about the issuer of the underlier. Neither we nor any of our affiliates undertakes to disclose any such information to you. In addition, we or our affiliates from time to time have published and in the future may publish research reports with respect to the issuer of the underlier, which may or may not recommend that investors buy or hold the underlier.

§ Hedging and trading activity by the issuer and its affiliates could potentially adversely affect the value of the securities. Hedging or trading activities of the issuer’s affiliates and of any other hedging counterparty with respect to the securities could adversely affect the value of the underlier and, as a result, could decrease the amount an investor may receive on the securities at maturity, if any. Any of these hedging or trading activities on or prior to the pricing date could potentially increase the initial underlier value and, as a result, the downside threshold level, which is the price at or above which the underlier must close on a determination date in order for you to receive a contingent quarterly payment and any unpaid contingent quarterly payments, or, if the securities are not redeemed prior to maturity, in order for you to avoid being exposed to the negative performance of the underlier at maturity. Additionally, such hedging or trading activities during the term of the securities could potentially affect the price of the underlier on the determination dates and, accordingly, whether investors will receive one or more contingent quarterly payments, whether the securities are automatically redeemed prior to maturity and, if the securities are not redeemed prior to maturity, the payment at maturity, if any.

§ We and our affiliates, and any dealer participating in the distribution of the securities, may engage in various activities or make determinations that could materially affect your securities in various ways and create conflicts of interest. We and our affiliates play a variety of roles in connection with the issuance of the securities, as described below. In performing these roles, our and our affiliates’ economic interests are potentially adverse to your interests as an investor in the securities.

In connection with our normal business activities and in connection with hedging our obligations under the securities, 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 underlier. In any such market making, trading and hedging activity, investment banking 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 securities. We and our affiliates have no obligation to take the needs of any buyer, seller or holder of the

December 2023 Page 14

Contingent Income Auto-Callable Securities due December 24, 2026

Based on the Performance of the Class A Common Stock of Rivian Automotive, Inc.

Principal at Risk Securities

securities 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 securities.

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

Furthermore, the selected dealer or its affiliates will have the option to conduct a material portion of the hedging activities for us in connection with the securities. The selected dealer or its affiliates would expect to realize a projected profit from such hedging activities, and this projected profit would be in addition to any selling concession that the selected dealer realizes for the sale of the securities to you. This additional projected profit may create a further incentive for the selected dealer to sell the securities to you.

In addition to the activities described above, we will also act as the calculation agent for the securities. As calculation agent, we will determine any values of the underlier and make any other determinations necessary to calculate any payments on the securities. In making these determinations, we may be required to make discretionary judgments, including determining whether a market disruption event has occurred on any date that the value of the underlier is to be determined; determining whether to adjust any variable described herein in the case of certain corporate events related to the underlier that the calculation agent determines have a diluting or concentrative effect on the theoretical value of the shares of the underlier; and determining whether to accelerate the maturity date upon the occurrence of certain reorganization events and additional adjustment events. In making these discretionary judgments, our economic interests are potentially adverse to your interests as an investor in the securities, and any of these determinations may adversely affect any payments on the securities.

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

§ The securities will not be listed on any securities exchange, and secondary trading may be limited. Barclays Capital Inc. and other affiliates of Barclays Bank PLC intend to offer to purchase the securities in the secondary market but are not required to do so and may cease any such market making activities at any time, without notice. Even if a secondary market develops, it may not provide enough liquidity to allow you to trade or sell the securities easily. Because other dealers are not likely to make a secondary market for the securities, the price, if any, at which you may be able to trade your securities 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 securities. In addition, Barclays Capital Inc. or one or more of our other affiliates may at any time hold an unsold portion of the securities (as described on the cover page of this document), which may inhibit the development of a secondary market for the securities. The securities are not designed to be short-term trading instruments. Accordingly, you should be willing and able to hold your securities to maturity.

§ The market price of the securities will be influenced by many unpredictable factors. Several factors will influence the value of the securities in the secondary market and the price at which Barclays Capital Inc. and other affiliates of Barclays Bank PLC may be willing to purchase or sell the securities in the secondary market. Although we expect that generally the value of the underlier on any day will affect the value of the securities more than any other single factor, other factors that may influence the value of the securities include:

o the volatility (frequency and magnitude of changes in value) of the underlier;

o whether the closing price has been, or is expected to be, below the downside threshold level on any determination date;

o dividend rates on the underlier;

o interest and yield rates in the market;

o time remaining until the securities mature;

o supply and demand for the securities;

o geopolitical conditions and economic, financial, political, regulatory and judicial events that affect the underlier and that may affect the final underlier value; and

o any actual or anticipated changes in our credit ratings or credit spreads.

The value of the underlier may be, and has recently been, volatile, and we can give you no assurance that the volatility will lessen. See “Rivian Automotive, Inc. Overview” below. You may receive less, and possibly significantly less, than the stated principal amount if you try to sell your securities prior to maturity.

§ The estimated value of your securities is expected to be lower than the initial issue price of your securities. The estimated value of your securities on the pricing date is expected to be lower, and may be significantly lower, than the initial issue price of your securities. The difference between the initial issue price of your securities and the estimated value of the securities is expected as a result of certain factors, such as any sales commissions expected to be paid to Barclays Capital Inc. or another affiliate of ours, any selling concessions, discounts, commissions or fees expected 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 securities, the estimated cost that we may incur in hedging our obligations under the securities, and estimated development and other costs that we may incur in connection with the securities. These other costs will include a fee paid to LFT Securities, LLC, an entity in which an affiliate of Morgan Stanley Wealth Management has an ownership interest, for providing certain electronic platform services with respect to this offering.

§ The estimated value of your securities 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 securities on the pricing 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 values referenced above might be lower if such estimated values were based on the levels at which our benchmark debt securities trade in the secondary market.

§ The estimated value of the securities 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 securities on the pricing 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 securities may not be consistent with those of other financial institutions that may be purchasers or sellers of securities in the secondary market. As a result, the secondary market price of your securities may be materially different from the estimated value of the securities determined by reference to our internal pricing models.

§ The estimated value of your securities is not a prediction of the prices at which you may sell your securities in the secondary market, if any, and such secondary market prices, if any, will likely be lower than the initial issue price of your securities and may be lower than the estimated value of your securities. The estimated value of the securities 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 securities 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 securities 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 securities. Further, as secondary market prices of your securities 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 securities such as fees, commissions, discounts, and the costs of hedging our obligations under the securities, secondary market prices of your securities will likely be lower than the initial issue price of your securities. As a result, the price at which Barclays Capital Inc., other affiliates of ours or third parties may be willing to purchase the securities from you in secondary market transactions, if any, will likely be lower than the price you paid for your securities, 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 securities 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 securities. Assuming that all relevant factors remain constant after the pricing date, the price at which Barclays Capital Inc. may initially buy or sell the securities in the secondary market (if Barclays Capital Inc. makes a market in the securities, 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 securities on the pricing date, as well as the secondary market value of the securities, for a temporary period after the initial issue date of the securities. The price at which Barclays Capital Inc. may initially buy or sell the securities 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 securities.

Additional Information about the Securities

Please read this information in conjunction with the terms on the cover page of this document.

Additional provisions:
Minimum ticketing size:	$1,000 / 1 security
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 with Associated Contingent Coupons” and, if you are a non-U.S. holder, “—Tax Consequences to Non-U.S. Holders.” The following discussion supersedes the discussion in the accompanying prospectus supplement to the extent it is inconsistent therewith. In determining our reporting responsibilities, if any, we intend to treat (i) the securities for U.S. federal income tax purposes as prepaid forward contracts with associated contingent coupons and (ii) any contingent quarterly payments as ordinary income, as described in the section entitled “Material U.S. Federal Income Tax Consequences—Tax Consequences to U.S. Holders—Notes Treated as Prepaid Forward or Derivative Contracts with Associated Contingent Coupons” in the accompanying prospectus supplement. Our special tax counsel, Davis Polk & Wardwell LLP, has advised that it believes this treatment to be reasonable, but that there are other reasonable treatments that the Internal Revenue Service (the “IRS”) or a court may adopt. Sale, exchange or redemption of a security. Assuming the treatment described above is respected, upon a sale or exchange of the securities (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 securities, which should equal the amount you paid to acquire the securities (assuming contingent quarterly payments are properly treated as ordinary income, consistent with the position referred to above). This gain or loss should be short-term capital gain or loss unless you hold the securities for more than one 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 the securities at the issue price. The deductibility of capital losses is subject to limitations. If you sell your securities between the time your right to a contingent quarterly payment is fixed and the time it is paid, it is likely that you will be treated as receiving ordinary income equal to the contingent quarterly payment. Although uncertain, it is possible that proceeds received from the sale or exchange of your securities prior to a determination date but that can be attributed to an expected contingent quarterly payment could be treated as ordinary income. You should consult your tax advisor regarding this issue. As noted above, there are other reasonable treatments that the IRS or a court may adopt, in which case the timing and character of any income or loss on the securities could be materially 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 and the relevance of factors such as the nature of the underlying property to which the instruments are linked. 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 affect the tax consequences of an investment in the securities, possibly with retroactive effect. You should consult your tax advisor regarding the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments and the issues presented by this notice. Non-U.S. holders. Insofar as we have responsibility as a withholding agent, we do not currently intend to treat contingent quarterly payments to non-U.S. holders (as defined in the accompanying prospectus supplement) as subject to U.S. withholding tax. However, non-U.S. holders should in any event expect to be required to provide appropriate Forms W-8 or other documentation in order to establish an exemption from backup withholding, as described under the heading “—Information Reporting and Backup Withholding” in the accompanying prospectus supplement. If any withholding is required, we will not be required to pay any additional amounts with respect to amounts withheld. 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, 2025 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 securities do not have a “delta of one” within the meaning of the regulations, we expect that these regulations will not apply to the securities 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

Use of proceeds and hedging:	The net proceeds we receive from the sale of the securities will be used for various corporate purposes as set forth in the prospectus and prospectus supplement and, in part, in connection with hedging our obligations under the securities through one or more of our subsidiaries.
