Barclays Bank PLC is offering market-linked, auto-callable notes due May 25, 2029

Each security has a $1,000 principal amount and pays a monthly contingent coupon (the contingent coupon rate will be set on the pricing date and will be at least 29.00% per annum). Payments, automatic calls and principal repayment depend on the lowest performing of Intel, Micron and Starbucks on monthly calculation days. The call price equals 90% of each starting price and the threshold price equals 50% of each starting price. If the securities are automatically called between November 2026 and April 2029, holders receive principal plus contingent coupon and any unpaid contingent coupons. If not called, maturity payment equals $1,000 if the lowest performing underlying is >= its threshold; otherwise maturity equals $1,000 times that lowest performing stock's performance factor, meaning investors can lose more than 50% (possibly all) of principal. All payments are subject to Barclays Bank PLC credit risk and holders consent to possible exercise of U.K. bail-in powers.
