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

***It is expected that delivery of the notes will be made against payment on November 3, 2025 (such settlement being referred to as "T+5"). Under Rule 15c6-1 under the Securities Exchange Act of 1934, 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 one business day before delivery of the notes hereunder will be required, by virtue of the fact that the notes initially settle in T+5, 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 prior their date of delivery hereunder should consult their advisors.***
