\*Note: A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time.

\*\*We expect that delivery of the notes will be made against payment therefor on or about August 27, 2025, which is seven business days following the date of pricing of the notes (this settlement cycle being referred to as "T+7"). 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 any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade their notes on any date prior to one business day before delivery will be required, by virtue of the fact that the notes initially will settle in T+7, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of notes who wish to trade their notes on any date prior to two business days before delivery should consult their own advisor.
