We expect that delivery of the Notes will be made to investors on or about February 19, 2026, which will be the fifth London business day and fourth New York business day following the date of this pricing supplement. Under the E.U. Central Securities Depositaries Regulation, trades in the secondary market generally are required to settle in two London business days, unless the parties to any such trade expressly agree otherwise. Also, under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in one business day unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes more than one business day prior to the settlement date will be required to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisors.
