Whether the securities pay a contingent coupon payment, whether the securities areautomatically called prior to stated maturity and, if they are not automatically called, whether you receive the face amount of your securities at stated maturity will depend, ineach case, on the stock closing price of the Underlying Stock on the relevant calculation day. ■Contingent Coupon.The securities will pay a contingent coupon payment on a monthly basis until the earlier of stated maturity or automatic call if,and only if, the stockclosing price of the Underlying Stock on the calculation day for that month is greater than or equal to the coupon threshold price. If the stock closing price of the UnderlyingStock on one or more calculation days is less than the coupon threshold price and, on a subsequent calculation day, the stock closing price of the Underlying Stock on thatsubsequent calculation day is greater than or equal to the coupon threshold price, the securities will pay the contingent coupon payment due for that subsequent calculation dayplus all previously unpaid contingent coupon payments (without interest on amounts previously unpaid). If the stock closing price of the Underlying Stock on a calculation dayis less than the coupon threshold price, you will not receive any contingent coupon payment on the related monthly contingent coupon payment date. In addition, if the stockclosing price of the Underlying Stock on a calculation day is less than the coupon threshold price and the stock closing price of the Underlying Stock on each subsequentcalculation day up to and including the final calculation day is less than the coupon threshold price, you will not receive the unpaid contingent coupon payments in respect ofthose calculation days. If the stock closing price of the Underlying Stock is less than the coupon threshold price on every calculation day, you will not receive any contingentcoupon payments throughout the entire term of the securities. The coupon threshold price for the Underlying Stock is equal to 65.00% of the starting price. The contingentcoupon rate will be determined on the pricing date and will be at least 16.10% per annum ■Automatic Call.If the stock closing price of the Underlying Stock on any of the monthly calculation days from December 2026 to May 2029, inclusive, is greater than or equalto the starting price, the securities will be automatically called for the face amount plus a final contingent coupon payment and any previously unpaid contingent couponpayments ■Potential Loss of Principal.If the securities are not automatically called prior to stated maturity, you will receive the face amount at stated maturity if,and only if, the stockclosing price of the Underlying Stock on the final calculation day is greater than or equal to the downside threshold price. If the stock closing price of the Underlying Stock onthe final calculation day is less than the downside threshold price, you will lose more than 35.00%, and possibly all, of the face amount of your securities.
