A securities rating is not a recommendation to buy, sell or hold securities and may be revised or withdrawn at any time.

(**)

It is expected that delivery of the notes will be made against payment therefor on or about July 16, 2026, which will be the third business day following the date of pricing of the notes, or “T+3.” Under Rule 15c6-1 of 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 notes before the business day prior to the delivery date, by virtue of the fact that the notes initially settle in T+3, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes before the business day prior to their date of delivery hereunder should consult their advisors.
