* 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 to deliver the notes on or about February 20, 2026, which will be the second business day following the date of this term sheet ("T+2"). Under Rule 15c6-1 under the Exchange Act, 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 notes on any day other than the business day preceding the settlement date will be required, by virtue of the fact that the notes initially will settle in T+2, to specify an alternate settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisors.
