If not called, at maturity holders receive the stated principal plus a maturity date premium of $1,000 × at least 99.40% only if the final underlier value is at least 60% of the initial underlier value; otherwise payment is $1,000 × (final underlier value / initial underlier value), exposing investors to full principal loss. Payments are unsecured obligations of Barclays and subject to U.K. Bail-in Power.

Barclays Bank PLC offers Buffered Performance Leveraged Upside Principal at Risk Securities ("Buffered PLUS") linked to the EURO STOXX 50® Index maturing on January 4, 2029.

Investors receive at maturity either: (a) the lesser of $1,000 plus a 200% leveraged upside (subject to a maximum payment of at least $1,337), (b) the $1,000 stated principal if the final index value is >= the 85% buffer level, or (c) a reduced amount equal to $1,000×(final/initial index) plus $150 (a minimum of $150), meaning investors can lose up to 85% of principal. Key dates: pricing date June 16, 2026, original issue date June 22, 2026, valuation date December 29, 2028. Payments and principal are unsecured obligations of Barclays Bank PLC and subject to the issuer's credit risk and possible exercise of U.K. Bail-in Power.

If the final underlier value is below the trigger (50% of the initial underlier value) investors suffer proportional losses on a 1:1 basis and may lose their entire investment. Payments are unsecured obligations of Barclays Bank PLC and are subject to issuer credit risk and potential exercise of U.K. Bail-in Power.

Barclays Bank PLC priced a $4,800,000 offering of Fixed Coupon Auto-Callable Securities due June 1, 2027. Each note has a stated principal of $1,000 and pays a quarterly coupon of $33.375 (3.3375%) subject to automatic early redemption on specified determination dates.

Redemption and maturity payments depend on the worst-performing of three equity underliers (Alphabet Class A, Meta Class A and NVIDIA). Initial underlier values on the May 26, 2026 pricing date were $388.88 (GOOGL), $612.34 (META) and $214.86 (NVDA); each has a 55% downside threshold. If final underlier performance for the worst-performing underlier is below its downside threshold, principal is reduced pro rata and could be lost in full. Payments are unsecured obligations of Barclays and subject to exercise of any U.K. Bail-in Power.

Barclays Bank PLC is offering Trigger Securities linked to the S&P 500® Index that mature on or about June 2, 2031. Each Security has a $10 principal amount and a 100.00% Participation Rate; if the Underlying Return is positive, holders receive principal plus the Underlying Return multiplied by the Participation Rate. If the Final Underlying Level on the Final Valuation Date is at or above the Downside Threshold (73.65% of the Initial Underlying Level), holders receive the $10 principal at maturity even when the Underlying Return is zero or negative. If the Final Underlying Level is below that threshold, holders suffer the full downside of the Underlying (and may lose all principal).

The pricing supplement highlights that the Securities pay no interest, are unsecured obligations of Barclays Bank PLC, require consent to possible exercise of U.K. Bail-in Power, and are subject to Barclays' creditworthiness. Key dates include a Strike Date of May 27, 2026, Trade Date May 28, 2026, Settlement Date June 2, 2026, Final Valuation Date May 28, 2031, and Maturity Date June 2, 2031.

Barclays Bank PLC is offering Capped Buffer GEARS linked to the SPDR® Gold Trust (GLD) with a $1,575,000 initial sale at $10.00 per Security and a maturity date of June 1, 2028. The product provides leveraged upside via an Upside Gearing of 2.0 subject to a Maximum Gain of 28.00%. A 10% buffer protects against the first 10% decline in the Underlying, but losses beyond the buffer fully expose investors (up to 90% principal loss). Payments and principal are unsecured obligations of Barclays and are subject to issuer credit risk and possible exercise of U.K. bail-in powers.

Barclays Bank PLC is offering Trigger Autocallable Contingent Yield Notes linked to the common stock of Valero Energy Corporation maturing on June 1, 2027.

The Notes will be automatically called if the Underlying closes at or above the Initial Underlying Price on any quarterly Observation Date; called Notes pay principal plus that quarter's Contingent Coupon.

If not called, maturity pays $1,000 plus the final Contingent Coupon only if the Final Underlying Price is at or above the Downside Threshold ($156.22, 65.00% of the Initial Underlying Price). If the Final Underlying Price is below that threshold, holders receive approximately 4.1608 shares of VLO per Note (fractional shares paid in cash), which may be worth significantly less than principal.
