* Note: A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision, suspension or withdrawal at any time. Each security rating should be evaluated independently of any other security rating.

** Note: It is expected that delivery of the Senior Notes will be made to investors on or about August 18, 2025, which will be the second business day following the date hereof (such 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 are required to settle in one business day unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Senior Notes on any date prior to the business day before delivery of the Senior Notes will be required, by virtue of the fact that the Senior Notes initially will settle in T+2, to specify an alternative settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the Senior Notes who wish to trade the Senior Notes prior to the delivery of the Senior Notes should consult their advisors.
