This information does not purport to be a complete description of these securities or the offering. Please refer to the Preliminary Prospectus Supplement and the Base Prospectus for a complete description.

This communication does not constitute an offer to sell or the solicitation of an offer to buy any securities in any jurisdiction to any person to whom it is unlawful to make such offer or solicitation in such jurisdiction.

It is expected that delivery of the Notes will be made against payment therefor on or about September 21, 2026, which will be the fifth business day following the date hereof (such settlement cycle being herein referred to as "T+5"). 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 the Notes prior to the date that is one business day preceding the settlement date will be required, by virtue of the fact that the Notes initially will settle T+5, 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 the Notes prior to the date that is one business day preceding the settlement date should consult their own advisor.
