*The issuer expects that delivery of the Notes will be made against payment therefor on or about November 20, 2025, which will be the third business day following the date of pricing of the Notes (this settlement cycle being herein referred to as “T+3”). Under Rule 15c6-1 under the U.S. Securities Exchange Act of 1934, as amended, 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 scheduled settlement date will be required, by virtue of the fact that the Notes initially will settle in T+3, to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the Notes who wish to make such trades should consult their own advisor.
