*	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.

This pricing term sheet relates only to the securities described above and should be read in conjunction with the preliminary prospectus supplement dated September 8, 2026 (the “Preliminary Prospectus Supplement”) relating to these securities. The information in this pricing term sheet supplements the Preliminary Prospectus Supplement and updates and supersedes the information in the Preliminary Prospectus Supplement to the extent it is inconsistent with the information in the Preliminary Prospectus Supplement.

The issuer expects that delivery of the notes will be made to investors on or about September 14, 2026, which will be the fourth business day following the date of this pricing term sheet (such settlement being referred to as “T+4”). Under Rule 15c6-1 under the Exchange Act, 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 notes prior to the date that is more than one business day preceding the settlement date will be required, by virtue of the fact that the notes initially settle in T+4, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes prior to the date that is more than one business day preceding the settlement date should consult their advisors.
