If the index closingvalueof anyunderlying indexis less than the coupon barrier level for such index onanyindex business dayduring an observation period, we will pay no contingentquarterly coupon for the related quarterly period. In addition, beginning on January 23, 2026,we will have the right to redeem the securities at our discretion on anyquarterly redemption datefor a redemption payment equal to the sum of the stated principal amount plus any contingent quarterly coupon otherwise due with respect to therelated observation period. An early redemption of the securities will not automatically occur based on the performance of the underlying indices. At maturity, if the securitieshave not previously been redeemed and the final index value ofeachunderlying index is greater than or equal to 70% of the respective initial index value, which we refer to asthe downside threshold level, the payment at maturity will be the stated principal amount and, if payable, the contingent quarterly coupon otherwise due with respect to thefinal observation period. If, however, the final index value ofanyunderlying index is less than its downside threshold level, investors will be exposed to the decline in the worstperforming underlying index on a 1-to-1 basis and will receive a payment at maturity that is less than 70% of the stated principal amount of the securities and could be zero.Accordingly, investors in the securities must be willing to accept the risk of losing their entire initial investment based on the performance of anyunderlying indexand also the risk of not receiving any quarterly coupons during the entire 2-year term of the securities.Because payments on the securities are based on theworst performing of the underlying indices, a decline beyond the respective coupon barrier level on any index business day during an observation period and/or beyond therespective downside threshold level on the final observation date, as applicable, ofanyunderlying index will result in the forfeiture of contingent quarterly coupons and/or asignificant loss of your investment, as applicable, even if the other underlying indices have appreciated or have not declined as much. Investors will not participate in anyappreciation in any underlying index. The securities are for investors who are willing to risk their principal and seek an opportunity to earn contingent quarterly couponpayments at a potentially above-market rate in exchange for the risk of receiving no contingent quarterly coupon payments ifanyunderlying indexcloses below the couponbarrier level for such index on any index business day during the related observation period, and the risk of an early redemption of the securities at our discretion.Thesecurities are our senior debt securities.
