If the stock closing price of the lowest performing Underlying Stock on one or morecalculation days is less than its coupon threshold price and, on a subsequent calculation day, the stock closing price of the lowest performing Underlying Stock on that subsequent calculation day isgreater than or equal to its coupon threshold price, the securities will pay the contingent coupon payment due for that subsequent calculation day plus all previously unpaid contingent coupon payments(without interest on amounts previously unpaid). If the stock closing price of the lowest performing Underlying Stock on a calculation day is less than its coupon threshold price, you will not receive anycontingent coupon payment on the related monthly contingent coupon payment date. In addition, if the stock closing price of the lowest performing Underlying Stock on a calculation day is less than itscoupon threshold price and the stock closing price of the lowest performing Underlying Stock on each subsequent calculation day up to and including the final calculation day is less than its couponthreshold price, you will not receive the unpaid contingent coupon payments in respect of those calculation days. If the stock closing price of the lowest performing Underlying Stock is less than its couponthreshold price on every calculation day, you will not receive any contingent coupon payments throughout the entire term of the securities. The coupon threshold price for each Underlying Stock is equal to60% of its starting price. The contingent coupon rate will be determined on the pricing date and will be at least 20.40% per annum ■AutomaticCall.If the stock closing price of the lowest performing Underlying Stock on any of the monthly calculation days from March 2026 to August 2028, inclusive, is greater than or equal to itsstarting price, the securities will be automatically called for the face amount plus a final contingent coupon payment and any previously unpaid contingent coupon payments ■PotentialLoss 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 stock closing price of the lowestperforming Underlying Stock on the final calculation day is greater than or equal to its downside threshold price. If the stock closing price of the lowest performing Underlying Stock on the final calculationday is less than its downside threshold price, you will lose more than 40%, and possibly all, of the face amount of your securities. The downside threshold pricefor each Underlying Stock is equal to 60%of its starting price ■Ifthe securities are not automatically called prior to stated maturity, you will have full downside exposure to the lowest performing Underlying Stock from its starting price if its stock closing price on the finalcalculation day is less than its downside threshold p
