The underwriters expect to deliver the Notes in book-entry form only through the facilities of The Depository Trust Company for the accounts of its participants, including Clearstream Banking, S.A. and Euroclear Bank S.A./N.V., as operator of the Euroclear System, against payment in New York, New York on or about January 28, 2026, which is the third business day following the date of the pricing of the Notes (such settlement cycle being referred to as “T+3”). Under Rule 15c6-1 promulgated under the Exchange Act, trades in the secondary market generally are required to settle in one Business Day unless the parties to a trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes on any date prior to one Business Day before the settlement date will be required, by virtue of the fact that the Notes initially will settle in T+3, to specify alternative settlement arrangements to prevent a failed settlement. Such purchasers should consult their own advisors.
