The Issuer expects to deliver the 2029 Notes and the 2030 Notes (collectively, the "Notes") against payment for the Notes on or about November 13, 2025, which will be the second business day following the date of the pricing of the Notes, or "T+2". Under Rule 15c6-1 under the Exchange Act, trades in the secondary market are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade Notes prior to the business day immediately preceding the settlement date will be required, by virtue of the fact that the Notes initially will settle T+2, to specify alternative settlement arrangements at the time of any such trade to prevent a failed settlement. Purchasers of the Notes who wish to trade the Notes prior to the business day immediately preceding the settlement date should consult their advisors.
