Barclays Bank PLC is offering Capped Leveraged Buffered Nasdaq-100 Index®-Linked Global Medium-Term Notes, Series A. These structured notes are unsecured, unsubordinated obligations that do not pay interest and are linked to the performance of the Nasdaq-100 Index® over roughly 17–20 months.

At maturity, for each $1,000 face amount, investors receive a cash payment based on index performance: 150% leveraged upside, capped at a maximum settlement amount expected between $1,175.80 and $1,206.25, and a 10% buffer against losses. If the index falls more than 10% from its initial level, principal is reduced and investors can lose their entire investment.

Payments depend on Barclays’ credit and are subject to potential U.K. Bail-in Power, the notes will not be listed on an exchange, their estimated value on the trade date will be lower than the $1,000 issue price, and secondary market liquidity is not assured.

Barclays Bank PLC is offering Trigger Jump Securities with an auto-callable feature due December 24, 2030. These are principal at risk structured notes linked to the worst performer of the Nikkei 225, Russell 2000® and S&P 500® indices, with a stated principal amount of $1,000 per security and no interest payments.

Quarterly from December 28, 2026, if each index is at or above its initial level on a determination date, the note is automatically redeemed for $1,000 plus a call premium starting at $1,000 × at least 13.80% and rising over time, up to a maturity date premium of $1,000 × at least 69.00% if held to December 19, 2030 and all indices finish at or above their initial levels.

If not called and the worst index is below its initial level but at or above 80% of that level at maturity, investors receive only $1,000; if the worst index ends below 80%, repayment is reduced 1% for each 1% decline, potentially to $0. The securities are unsecured, unsubordinated obligations of Barclays Bank PLC, subject to U.K. Bail-in Power, sold at $1,000 with agent’s commissions of $27.50 per security plus $5.00, and are not listed on any exchange.

Barclays Bank PLC is offering unsecured, unsubordinated notes linked to the Russell 2000® (RTY Index) and S&P 500® (SPX Index). The Notes pay a Contingent Coupon of $43.75 per $1,000 (an annual rate of 8.75%, paid semiannually) only if on an Observation Date the Closing Value of each index is at or above 75% of its Initial Underlier Value, the Coupon Barrier Value. If either index is below its barrier, no coupon is paid for that period.

At maturity in December 2028, if the Final Underlier Value of the lesser‑performing index is at or above 75% of its initial level, investors receive $1,000 per $1,000 Note plus any due Contingent Coupon. If it is below this Barrier Value, repayment is reduced in line with the index decline, potentially down to zero, so all principal can be lost.

The initial issue price is $1,000 per Note, with total offering size of $4,710,000, a 0.80% selling commission and 99.20% proceeds to Barclays. The Notes will not be listed on a U.S. exchange, carry Barclays’ credit risk, and are subject to possible write‑down, conversion or modification under the U.K. Bail‑in Power. Barclays’ estimated value on the Initial Valuation Date is less than the issue price.

Barclays Bank PLC is offering Capped GEARS, $10 structured notes whose return is linked to an equally weighted basket of three bank stocks: The Goldman Sachs Group, Inc., JPMorgan Chase & Co., and Morgan Stanley. The notes run from a Trade Date of December 29, 2025 to a Maturity Date of March 3, 2027, with no interim interest payments.

At maturity, if the basket has risen, investors receive $10 plus three times the Basket Return (Upside Gearing of 3.0), but gains are capped by a Maximum Gain between 24.00% and 26.40%, set on the Trade Date. If the Basket Return is zero, only the $10 principal is repaid. If the Basket Return is negative, repayment is $10 plus the Basket Return, giving full downside exposure and potential loss of the entire principal.

The notes are unsecured, unsubordinated obligations of Barclays Bank PLC, subject to its credit risk and to possible exercise of U.K. Bail-in Power, which can reduce, convert, or cancel amounts due. The initial issue price is $10 per Security, including a $0.20 underwriting discount (proceeds of $9.80 to Barclays per Security), and the minimum investment is $1,000.

Barclays Bank PLC is issuing $41,044,250 of Trigger Callable Contingent Yield Notes linked to the least performing of the Nasdaq-100, Russell 2000 and S&P 500 indices, maturing in March 2029. The Notes pay a 10.30% per annum contingent coupon (about $0.2575 per $10 each quarter) only if, on every trading day in a quarter, all three indices stay at or above their Coupon Barriers set at 70% of their initial levels. Barclays may call the Notes on any quarterly observation end date (except the final one), repaying principal plus any due coupon.

If the Notes are not called and on the final valuation date all indices are at or above their Downside Thresholds set at 60% of initial levels, investors receive full principal back plus any final coupon. If any index finishes below its Downside Threshold, repayment is reduced one-for-one with the decline of the worst index, and investors can lose all principal. The Notes are unsecured obligations of Barclays, subject to its credit risk and potential U.K. Bail-in Power. The issue price is $10 per Note, with an estimated value of $9.873 on the trade date.

Barclays Bank PLC is offering two-year structured notes linked to the S&P 500® Index that do not pay interest and can result in a loss of principal. Each $1,000 denomination note offers a fixed digital return of 20.60%, so if the index’s final value is at or above its initial value on the December 16, 2027 valuation date, investors receive $1,206 at maturity. If the index declines but stays at or above a barrier set at 75.00% of the initial level, investors receive their $1,000 principal back.

If the final index value falls below the barrier, repayment is reduced one-for-one with the index loss, and investors can lose up to 100.00% of principal. The notes are unsecured, unsubordinated obligations of Barclays, are subject to the exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority, and will not be listed on a U.S. securities exchange. Barclays expects the notes’ estimated value on the pricing date to be less than the $1,000 issue price, and secondary market prices are expected to be lower than the initial issue price.

Barclays Bank PLC is offering Capped Buffer GEARS, a type of structured note linked to the S&P 500® Index, with a term of approximately two years. Each Security has a $10 principal amount and provides 2.0x leveraged exposure to positive index performance, up to a Maximum Gain between 21.30% and 23.30%, set on the Trade Date. If the index is flat or down but stays at or above a 10% downside Buffer, investors receive their $10 principal at maturity. If the index falls below the Downside Threshold, investors lose 1% of principal for each 1% decline beyond the 10% Buffer, with the potential to lose up to 90% of principal. The notes pay no interest or dividends and all payments depend on the creditworthiness of Barclays and are also subject to potential U.K. Bail-in Power.

Barclays Bank PLC is offering Capped Buffer GEARS, which are unsecured notes linked to the S&P 500® Index. Each Security has a $10 principal amount and a term of approximately two years, from a Trade Date of December 29, 2025 to a Maturity Date of December 31, 2027.

If the index return is positive, holders receive $10 plus twice the index gain (Upside Gearing of 2.0), capped at a Maximum Gain between 17.25% and 19.25%. If the index is flat or down but no more than 10% below its initial level, investors receive their $10 back. If the index falls more than 10%, investors lose 1% of principal for every 1% decline beyond the 10% buffer and can lose up to 90% of principal.

The notes pay no interest, will not be listed on any exchange, and all payments depend on the credit of Barclays Bank PLC and are subject to potential U.K. Bail-in Power. The estimated value on the Trade Date is expected to be below the $10 issue price, reflecting selling costs, hedging and structuring margins.

Barclays Bank PLC is issuing $1,306,000 of Phoenix AutoCallable Notes due December 15, 2028, linked to the Class A common stock of Coinbase Global, Inc.

The Notes pay a contingent coupon of $61.25 per $1,000 (24.50% per annum) on scheduled dates only if Coinbase’s closing price is at or above the $160.48 Coupon Barrier Value, which is 60.00% of the $267.46 Initial Value. Beginning March 12, 2026, the Notes are automatically called at $1,000 plus the coupon if the stock is at or above the $267.46 Call Value on a Call Valuation Date.

If not called, holders receive $1,000 at maturity only if the Final Value is at or above the $160.48 Barrier Value; otherwise the payoff is reduced in line with the stock’s loss and up to 100.00% of principal can be lost. The Notes are unsecured, subject to Barclays’ credit risk and any exercise of U.K. Bail-in Power, are not listed on an exchange, and had an estimated value of $946.90 per $1,000 on the Initial Valuation Date, below the issue price.

Barclays Bank PLC is offering unsecured notes that pay no interest and do not guarantee full return of principal. The notes are linked to the Dow Jones Industrial Average, Nasdaq-100 Index and Russell 2000 Index, and can be automatically redeemed for a fixed premium if all three indexes are at or above their initial levels on specified observation dates.

Each $1,000 note returns principal plus a redemption premium of 11.50%, 23.00% or 34.50% on successive observation dates if the automatic redemption condition is met. If the notes are not called, investors receive either full principal, or one-for-one upside or downside based on the least performing index, with protection only down to 70.00% of its initial value; a larger drop can reduce repayment to zero. Barclays expects to receive 96.15% of the issue price per note after a 3.85% selling commission. The notes are subject to U.K. Bail-in Power, will not be listed on an exchange and carry complex market, liquidity and tax risks.

Barclays Bank PLC is offering unsecured, unsubordinated structured notes linked to the Russell 2000® Index and the S&P 500® Index. Each note has a $1,000 denomination and offers a contingent monthly coupon of $6.25 per $1,000 (7.50% per annum) only when, on an observation date, the closing value of each index is at least 70.00% of its initial value.

On the December 22, 2028 maturity date, if the final value of the lesser-performing index is at or above 70.00% of its initial value, investors receive $1,000 per note plus any due coupon. If that index finishes below its 70.00% barrier, the payoff is reduced in line with its loss, using $1,000 + ($1,000 × Underlier Return), so principal can be cut substantially or lost entirely, and gains in the better-performing index do not increase the maturity payment.

All payments depend on the credit of Barclays Bank PLC and are subject to potential use of the U.K. Bail-in Power, which can reduce, cancel, convert or amend the notes. The notes are not insured deposits, will not be listed on any U.S. securities exchange, and their estimated value on the pricing date is expected to be below the $1,000 issue price due to commissions, hedging costs, structuring profit and other issuer expenses.

Barclays Bank PLC is offering unsecured auto-callable notes linked to the Dow Jones Industrial Average, Nasdaq-100 Index and Russell 2000 Index. The notes have a $1,000 minimum denomination, pay no interest, and can be automatically redeemed after the first year if on an observation date each index is at or above its initial level, paying $1,000 plus a fixed redemption premium of 14.65%, 29.30% or 43.95% depending on when they are called.

If not called, the maturity payment depends on the “least performing” index. Investors receive full principal back if that index finishes at or above 70.00% of its initial level, upside exposure if it finishes above its initial level, and one-for-one downside if it falls below the 70.00% barrier, which can result in losing all principal. The notes are subject to Barclays’ credit risk, potential U.K. bail-in powers, are not listed on an exchange, and are expected to have an estimated value below the $1,000 issue price.

Barclays Bank PLC is offering Capped GEARS, unsecured notes with a $10 principal amount per Security, linked to an unequally weighted basket of five equity indices: EURO STOXX 50®, Nikkei 225, FTSE® 100, Swiss Market Index and S&P/ASX 200. The basket weights are 40.00%, 25.00%, 17.50%, 10.00% and 7.50%, so the first three indices drive most of the result. The term is approximately 13 months, from a Trade Date on December 26, 2025 to a Maturity Date on February 1, 2027.

If the Basket Return is positive, investors receive principal plus 3.0 times that return, capped by a Maximum Gain that will be set on the Trade Date between 14.00% and 16.26% (for example, a 14.00% cap means a maximum payment of $11.40 per $10 Security). If the Basket is flat, only the $10 principal is repaid. If the Basket Return is negative, repayment is reduced one-for-one with the Basket’s loss, so investors can lose some or all of their principal. The notes pay no interest, will not be listed on any securities exchange, and all payments depend on the credit of Barclays Bank PLC and are subject to potential exercise of U.K. Bail-in Power. The minimum investment is $1,000 (100 Securities), with an initial issue price of $10.00, an underwriting discount of $0.20 and proceeds to Barclays of $9.80 per Security.

Barclays Bank PLC is offering unsecured, index-linked notes tied to the Dow Jones Industrial Average, Nasdaq-100 Index and Russell 2000 Index. The notes pay no interest and may be automatically redeemed starting with observation dates from December 2026 if all three indices are at or above their initial values, providing fixed redemption premiums of 11%, 22%, 33% or 44% depending on when this occurs.

If the notes are not redeemed early, maturity payments depend on the worst-performing index. If that index finishes above its initial level, investors receive 1.50 times its gain; if it finishes between 70% of its initial level and the initial level, principal is returned; if it falls below 70%, repayment is reduced one-for-one with the decline, up to total loss of principal. The notes are not listed, are subject to Barclays’ credit risk and potential U.K. Bail-in Power, and the issuer’s estimated value on the initial valuation date will be lower than the $1,000 issue price because of commissions, hedging and structuring costs.

Barclays Bank PLC is offering Capped GEARS, unsecured and unsubordinated notes linked to the VanEck^® Semiconductor ETF (SMH), maturing on March 3, 2027. Each Security has a $10 principal amount and pays no interest.

If the ETF’s return over the term is positive, investors receive $10 plus a leveraged gain equal to three times the ETF’s percentage increase, capped by a Maximum Gain between 30.00% and 33.90% set on the December 29, 2025 Trade Date. If the ETF is flat, only the $10 principal is repaid. If the ETF declines, repayment falls dollar‑for‑dollar with the negative return, exposing investors to full downside and potential total loss of principal.

The notes are subject to Barclays’ credit risk and to potential use of U.K. Bail‑in Power, are not insured or guaranteed by any government agency, and will not be listed on an exchange. The initial issue price is $10 per Security, including a $0.20 underwriting discount, with minimum investment of $1,000 (100 Securities).

Barclays Bank PLC is offering unsecured, unsubordinated structured Notes linked to the Nasdaq-100, Russell 2000 and S&P 500 indices. The Notes pay no interest and do not guarantee full principal repayment at maturity. Instead, for each $1,000 Note, investors receive a fixed return if the least performing index is at or above its initial level, equal to $1,000 plus $1,000 × the 18.50% Digital Percentage.

If the least performing index finishes below its initial level but at or above its Barrier Value of 60.00% of the initial level, investors receive $1,000 per Note. If it finishes below this barrier, repayment is reduced in line with the index loss, and investors can lose up to 100.00% of principal. All payments depend on Barclays Bank PLC’s credit and are subject to potential exercise of the U.K. Bail-in Power by the U.K. resolution authority.

Barclays Bank PLC is offering $5,000-denomination structured notes linked to the Invesco QQQ Trust and the SPDR S&P 500 ETF. The notes pay a fixed coupon of $30.417 per $5,000 on each monthly coupon date, equal to 7.30% per year, but repayment of principal at maturity is not guaranteed.

The payoff is based on the “lesser performing” ETF. If its final value is at least 75% of its initial level, investors receive $5,000 per note at maturity plus the final coupon. If it finishes below this barrier, investors receive a preset number of shares of the worst-performing ETF, or the cash value of those shares, which may be far below the original investment and could be worth nothing. Investors do not participate in any ETF price gains beyond the coupons.

The notes are unsecured and unsubordinated obligations of Barclays, exposed to its credit risk and to potential use of U.K. bail-in powers, which could reduce, convert or cancel amounts owed. The initial issue price is $5,000 per note, including a 1.00% selling commission, with 99.00% of proceeds to Barclays, and the bank’s estimated fair value on the initial valuation date is lower than the issue price.

Barclays Bank PLC is offering unsecured, unsubordinated structured notes that pay a monthly contingent coupon of $5.542 per $1,000 note (a 6.65% annual rate) when the Dow Jones Industrial Average, Nasdaq-100 Index and S&P 500 Index are each at or above 75% of their initial levels on scheduled observation dates.

At maturity, investors receive full principal only if the worst-performing index is at least 60% of its initial level; otherwise, repayment is reduced in proportion to that index’s loss and can fall to $0, so principal is at risk.

The notes will not be listed, do not provide any index dividends, and all payments depend on Barclays’ credit and possible use of U.K. bail-in powers, which can write down, convert or amend the notes. The initial issue price is $1,000 per note, with a 0.85% selling commission.

Barclays Bank PLC is offering unsecured structured Notes linked to the common stock of NVIDIA Corporation (NVDA). The Notes pay no interest and do not guarantee full principal repayment at maturity on June 16, 2027, with an initial valuation on December 11, 2025. Instead, investors receive unleveraged exposure to NVIDIA’s share performance within defined limits.

If NVIDIA’s closing value at maturity is above the initial value of $180.93, investors earn the stock’s gain up to a Maximum Upside Return of 36.40%, for a maximum payment of $1,364 per $1,000 Note. If the final value is below the initial value but at or above the Buffer Value of $144.74 (a 20.00% decline), investors earn a positive 1% return for each 1% decline, capped at 20.00%.

If NVIDIA’s final value falls below the Buffer Value, principal is reduced based on losses beyond the 20.00% buffer, and investors can lose up to 80.00% of their investment. The minimum denomination is $1,000. An agent’s commission of 1.50% produces proceeds to Barclays of 98.50% of face value, or $1,139,645 on a total initial issue price of $1,157,000. Payments depend on Barclays’ credit and are subject to potential U.K. Bail-in Power; the Notes are not insured or guaranteed by any government agency.

Barclays Bank PLC is offering Performance Leveraged Upside Securities (PLUS) linked to the TOPIX® Index, maturing on April 5, 2027. Each PLUS has a stated principal amount of $1,000 and pays no interest.

At maturity, if the TOPIX final level is above its initial level, holders receive the lesser of $1,000 plus 300% of the index gain or a maximum payment of at least $1,247.50 (124.75% of principal). If the final level is at or below the initial level, the payout is $1,000 multiplied by the index performance ratio, giving 1:1 downside exposure and potentially a total loss of principal.

The PLUS are unsecured, unsubordinated obligations of Barclays and are subject to U.K. Bail-in Power, which can write down, convert, or cancel the notes without investor consent. They will not be listed on any exchange, and the issuer expects the initial estimated value on the pricing date to be below the $1,000 issue price due to commissions, hedging and structuring costs.

Barclays Bank PLC is offering unsecured Autocallable Contingent Coupon Barrier Notes due December 22, 2028, linked to the common stock of Amazon.com, Inc., NVIDIA Corporation and Palantir Technologies Inc. The notes are issued in $1,000 denominations and pay a quarterly contingent coupon of $39.125 per $1,000 (a 15.65% annual rate) only when, on an observation date, each stock closes at or above a coupon barrier set at 50.00% of its initial level.

Starting with the second observation date, the notes are automatically redeemed if all three stocks are at or above their initial values, returning $1,000 per note plus the current coupon and any unpaid coupons. If not redeemed early, principal repayment at maturity depends on the least-performing stock: full $1,000 is repaid only if that stock finishes at or above its 50.00% barrier, or if at least one stock is at or above its initial value; otherwise, repayment is reduced in line with the least performer, up to a total loss. The estimated value on the initial valuation date is expected to be between $876.10 and $936.10 per $1,000, the notes will not be listed, and all payments are subject to Barclays’ credit and potential U.K. bail-in powers.

Barclays Bank PLC is offering $9,000,000 of AutoCallable Notes due December 16, 2030, linked to the Russell 2000 Index and the EURO STOXX 50 Index. The notes are issued in $1,000 denominations and can be automatically called on scheduled dates starting in March 2026 if each index is at or above its Initial Value.

If called, investors receive $1,000 plus a Call Premium that accrues at $115 per $1,000 per year (an 11.50% per annum rate), leading to example payouts from $1,028.75 on the first call date up to $1,575.00 per $1,000 if redeemed on the final call date. If the notes are not called, and at maturity the least performing index is at or above 75% of its Initial Value, investors receive $1,000; if it finishes below that barrier, repayment is reduced one-for-one with the index loss, and up to 100% of principal can be lost.

The notes are unsecured, unsubordinated obligations of Barclays Bank PLC, subject to the consented U.K. Bail-in Power, pay no coupons or dividends, and will not be listed on any exchange. The price to the public is $1,000 per note with a 3.05% selling commission, while Barclays’ estimated value on the Initial Valuation Date is $966.80 per note, highlighting structural and distribution costs and potential secondary-market pricing below issue price.

Barclays Bank PLC is issuing $670,000 of unsecured Phoenix AutoCallable Notes due December 16, 2030, linked to the least performing of U.S. Bancorp, The Mosaic Company, and Comcast common stock. The notes pay a contingent quarterly coupon of $21.375 per $1,000 (about 25.65% per year) only if, on each Observation Date, the closing value of every reference stock is at or above its Coupon Barrier, set at 69% of its initial value.

The notes may be automatically called as early as December 11, 2026 if, on a Call Valuation Date, each stock is at or above its Call Value (100% of its initial value). If called, investors receive $1,000 per note plus the applicable contingent coupon, and no further payments. If held to maturity without being called, investors receive $1,000 per note only if the least performing stock finishes at or above its Barrier Value, set at 86% of its initial value; otherwise, repayment is reduced one-for-one with the stock’s decline, and investors can lose up to all principal.

The initial issue price is $1,000 per note, but Barclays’ internal estimated value on the initial valuation date is $917.10, reflecting fees, hedging costs, and issuer profit. The notes are subject to Barclays’ credit risk and to potential write-down, conversion, or cancellation under U.K. Bail-in Power, and they will not be listed on any securities exchange.

Barclays Bank PLC is offering unsecured, unsubordinated callable contingent coupon notes maturing in December 2028, linked to the worst performer of the S&P 500, Russell 2000 and Nasdaq-100 indices.

At maturity, if the notes are not called and the worst-performing index is at or above its 60% barrier, investors receive full principal; if it is below, repayment is reduced one-for-one with the index loss, up to a total loss of principal. Barclays may redeem the notes in whole on specified call dates at $1,000 plus any due coupon. The notes are subject to Barclays’ credit risk and to potential write-down or conversion under the U.K. Bail-in Power, and the bank’s estimated initial value of each note, $925.80–$985.80, is below the $1,000 issue price.

The notes can be automatically called as early as June 11, 2026 if Marvell’s stock closes at or above the initial value of $89.43 on a call valuation date, returning $1,000 per note plus the coupon.

If the notes are not called, investors receive $1,000 per note at maturity only if Tesla’s final share price is at or above the 50% barrier of the initial price; otherwise, repayment is reduced in line with Tesla’s decline, and investors may lose up to 100% of principal.

The notes are unsecured obligations of Barclays, subject to its credit risk and to potential loss under the U.K. Bail-in Power, and will not be listed on any exchange. Barclays’ estimated value on the initial valuation date is $948.70 per $1,000 note, below the issue price.

The notes pay contingent coupons of $27.50 per $1,000 (an annual rate of 11.00%) only when both stocks are at or above 60.00% of their initial values on specified observation dates; missed coupons may accrue as unpaid amounts but can be lost if conditions are never met. If the notes are not called and the worst-performing stock finishes at or above its 60.00% barrier, investors receive full principal back, but if it ends below that barrier, repayment is reduced one-for-one with the stock’s loss, up to a complete loss of principal, potentially settled in shares under Barclays’ physical settlement option. The notes are unsecured, unsubordinated obligations of Barclays Bank PLC, subject to U.K. Bail-in Power, not insured by deposit protection schemes, not listed on an exchange, and have an estimated initial value of $925.90–$975.90 per $1,000, below the issue price due to commissions, hedging and structuring costs.

Barclays Bank PLC is offering unsecured notes linked to the Dow Jones Industrial Average, Nasdaq‑100 Index and S&P 500 Index, maturing on December 20, 2028. The notes pay a monthly contingent coupon of $5.542 per $1,000 (6.65% per year) only if on an Observation Date each index is at or above 75% of its initial level; missed coupons accumulate and are paid once this condition is next met.

At maturity, if the worst‑performing index is at or above 60% of its initial level, investors receive $1,000 per note plus any due coupons. If the worst index finishes below this barrier, repayment is reduced in line with its loss, so a 50% decline would return $500 per $1,000 and a 100% decline would return $0, meaning investors can lose their entire principal.

The notes do not participate in index gains, carry the credit risk of Barclays Bank PLC and are subject to potential U.K. bail‑in powers. They will not be listed on an exchange, and Barclays expects the notes’ internal estimated value on the pricing date to be less than the $1,000 issue price due to commissions, hedging and structuring costs.

Barclays Bank PLC is offering unsecured notes linked to the common stock of Tesla, Inc. that pay no interest and may not return full principal. Each note has a $1,000 denomination.

Approximately one year after issuance, if Tesla’s closing price on the observation date is at or above its initial value, the notes are automatically redeemed for $1,150 per $1,000, a fixed 15% redemption premium that does not increase with further stock gains. If not redeemed, at maturity in December 2030 investors receive 1.805 times Tesla’s positive return, full principal back if Tesla is flat or down but no more than 25%, and one-for-one loss of principal if Tesla falls more than 25% from the initial value.

All payments depend on the credit of Barclays and are subject to possible write-down, conversion, cancellation or term changes under the U.K. Bail-in Power. The notes are not insured, will not be listed on an exchange, have an estimated value below the $1,000 issue price due to fees and hedging costs, and may face conflicts of interest and limited secondary market liquidity.

Barclays Bank PLC is offering Phoenix AutoCallable Notes linked to the least-performing of the S&P 500, Russell 2000 and Nasdaq‑100 indices, maturing on June 23, 2027. Each Note has a $1,000 denomination and pays a contingent monthly coupon of $8.458 (about 10.15% per annum) only if, on each Observation Date, all three indices are at or above 70% of their Initial Values.

Starting about three months after issuance, the Notes are automatically called if on a Call Valuation Date each index is at or above 100% of its Initial Value, returning $1,000 plus the coupon and ending the investment. If the Notes are not called and held to maturity, investors receive $1,000 per Note only if the least-performing index is at or above its 70% Barrier Value; otherwise, repayment is reduced one‑for‑one with that index’s decline, and investors may lose up to 100% of principal.

The Notes are unsecured, unsubordinated obligations of Barclays Bank PLC, subject to its credit risk and to potential exercise of the U.K. Bail‑in Power, and will not be listed on any exchange. The initial issue price is $1,000 per Note, while Barclays’ estimated value on the Initial Valuation Date is expected to be between $934.00 and $984.00, reflecting commissions, hedging, and structuring costs.

The notes have a $1,000 minimum denomination and pay a contingent coupon of $46.25 per quarter per $1,000 note, equal to 18.50% per annum, but only when the stock closes on an observation date at or above the coupon barrier of $75.57 (60% of the $125.95 initial value).

The notes can be automatically called on scheduled call dates starting about three months after issuance if the stock is at or above the call value of $100.76 (80% of the initial value), in which case investors receive $1,000 plus the applicable contingent coupon and the notes terminate. If the notes are never called and the final stock value is at or above the barrier value of $62.98 (50% of the initial value), principal is repaid in full; if it is below the barrier, repayment is reduced one-for-one with the stock’s loss, up to a total loss of principal.

The initial issue price is $1,000 per note, but Barclays’ own estimated value on the pricing date is $979.40, reflecting dealer commissions and structuring and hedging costs.

The notes may be automatically redeemed quarterly from March 2026 through November 2026, or on the final valuation date in December 2026, if the closing value of each ETF is at or above its call value. In that case, holders receive $1,000 plus a fixed Redemption Premium of 3% to 12%, depending on the observation date, and no further payments.

If the notes are not called, maturity payment depends on the “Least Performing Underlier.” If its final value is at least 60% of its initial value, holders receive $1,000 per note. If it is below 60%, repayment is reduced one-for-one with the ETF’s loss, up to a total loss of principal. The notes are not listed, are subject to U.K. bail-in powers, and are sold at 100% of issue price with a 2.325% selling commission.

Investors pay $10 per Note and may receive a quarterly Contingent Coupon at a 10.30% per annum rate, but only if on every scheduled trading day in an Observation Period each index stays at or above its Coupon Barrier set at 70% of its Initial Level. Barclays can elect to call the Notes on any quarterly Observation End Date (except the Final Valuation Date), in which case investors receive principal plus any due coupon and the product terminates.

If the Notes are not called and, on the Final Valuation Date, each index is at or above its Downside Threshold set at 60% of its Initial Level, investors receive full principal back plus any final coupon. If any index finishes below its Downside Threshold, repayment is reduced in line with the loss on the worst-performing index, up to a complete loss of principal. Payments depend on Barclays’ credit and are also subject to potential U.K. Bail-in Power.

The notes pay a monthly contingent coupon of $8.958 per $1,000 (a 10.75% per annum rate) only if, on an Observation Date, the closing value of each stock is at or above 70% of its initial value. Beginning with the third Observation Date, if each stock is at or above its initial value, the notes are automatically redeemed at $1,000 plus the due coupon amounts, and no further payments are made.

If the notes are not redeemed early, principal repayment at maturity depends on the worst and best performing stocks. Full principal is repaid only if the least performing stock ends at or above its 70% barrier, or if the best performer finishes at or above its initial value. If all stocks finish below their initial values and the least performer is below its barrier, repayment is reduced in line with that stock’s loss, and investors can lose up to 100% of principal.

If the index is below its initial level but not more than 10.00% lower, the notes provide a positive 1% return for each 1% decline, up to 10.00%.

Barclays Bank PLC is offering $13,476,000 of Contingent Income Auto-Callable Securities linked to The Walt Disney Company common stock, maturing on December 10, 2026.

Each $1,000 security can pay a contingent quarterly coupon of $25.00 (2.50% of principal) for any determination date when Disney’s closing price is at or above the $78.98 downside threshold, which is 75% of the $105.30 initial underlier value. If Disney closes at or above the initial value on any non-final determination date, the notes are automatically redeemed for $1,000 plus that quarter’s coupon.

If the notes are not called and the final share price is at or above the downside threshold, investors receive $1,000 plus the last coupon at maturity. If the final price is below the threshold, repayment equals $1,000 multiplied by the ratio of final to initial price, so investors lose 1% of principal for each 1% Disney has fallen and can lose their entire investment. The notes are unsecured, unsubordinated obligations of Barclays, not listed on any exchange, and are subject to U.K. Bail-in Power and credit risk. Barclays’ estimated value on the pricing date is less than the $1,000 issue price, reflecting commissions, hedging and structuring costs.

The notes pay a fixed coupon of $12.50 per $1,000 principal amount (a 15.00% per annum rate) on scheduled payment dates until maturity or automatic redemption.

Beginning about one year after issuance, if on any call valuation date Micron’s closing price is at or above the initial value of $234.16, the notes are automatically called for $1,000 per note plus the applicable coupon, with no further payments. If not called, holders receive $1,000 per note at maturity only if the final Micron price is at or above the barrier of $117.08, which is 50.00% of the initial value; below the barrier, repayment of principal is reduced in line with Micron’s decline and can fall to zero.

They will not be listed on any U.S. securities exchange and may have limited secondary market liquidity.

If on any quarterly determination date before the final one the stock closes at or above the $49.20 initial value, the securities are automatically redeemed for $1,000 plus that coupon and no further payments are made. If they are not redeemed and the final stock price is at or above the $31.98 threshold, investors receive $1,000 plus the last coupon at maturity. If the final price is below the threshold, the maturity payment equals $1,000 multiplied by the ratio of the final price to $49.20, so investors lose 1% of principal for every 1% decline and may receive less than 65% of principal, down to zero.

The securities are unsecured, unsubordinated obligations of Barclays, subject to its credit and to the U.K. Bail-in Power, will not be listed on an exchange, and have an estimated value on the pricing date below the $1,000 issue price because of sales commissions, hedging costs, structuring profit and other offering expenses.

Investors can lose up to 100% of principal, receive no coupons, and are also exposed to Barclays’ credit risk and the possibility of a U.K. bail-in that could reduce or cancel payments.
