**We expect to deliver the notes against payment for the notes on or about August 13, 2026, which will be the second business day following the date of the pricing of the notes (this settlement cycle being referred to as “T+2”). Under Rule 15c6-1 under the 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 a trade expressly agree otherwise. Accordingly, purchasers who wish to trade their notes prior to the business day before settlement will be required, by virtue of the fact that the notes initially will settle in T+2, to specify alternative settlement arrangements to prevent a failed settlement. Purchasers of the notes who wish to trade their notes prior to the business day before settlement should consult their own advisors.
