⁽¹⁾           Note: A security rating is not a recommendation to buy, sell or hold securities and should be evaluated independently of any other rating. Each rating is subject to revision or withdrawal at any time by the assigning rating organization.

⁽²⁾            It is expected that delivery of the notes will be made against payment therefor on or about August 6, 2025, which is the second business day following the date hereof. Under Rule 15c6-1 of 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 that trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on any date prior to the first business day before delivery will be required, by virtue of the fact that the notes initially will settle in T+2, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement. Purchasers of the notes who wish to trade the notes prior to their date of delivery hereunder should consult their own advisors.
