A securities rating is not a recommendation to buy, sell or hold securities. Ratings may be subject to revision or withdrawal at any time by the assigning rating organization. Each rating should be evaluated independently of any other rating.

We expect that delivery of the notes will be made against payment for the notes on or about March 3, 2026, which will be the fourth business day following the trade date of February 25, 2026 (this settlement cycle being referred to as “T+4”). 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 any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes on any date prior to the date that is one business day preceding the settlement date will be required, by virtue of the fact that the Notes will initially settle in T+4, to specify alternative settlement arrangements to prevent a failed settlement and should consult their own investment advisor.
