The information in this pricing term sheet relates only to the offering of the Notes and should be read together with (i) the preliminary prospectus supplement, dated March 5, 2026, as filed with the Securities and Exchange Commission (the "SEC") pursuant to Rule 424(b) under the Securities Act of 1933, as amended (the "Preliminary Prospectus Supplement"), and (ii) the related base prospectus dated March 1, 2024, included in the Registration Statement (File No. 333-277563), in each case, including the documents incorporated by reference therein. Terms used but not defined herein have the meanings assigned to such terms in the Preliminary Prospectus Supplement.

* A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time.

** The Issuer expects that delivery of the Notes will be made against payment therefor on or about the settlement date specified in this pricing term sheet, which will be the second business day following the date of pricing of the Notes (this settlement cycle being referred to as "T+2"). Pursuant to 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 that trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes prior to the first business day before settlement 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 a failed settlement and should consult their own advisor.
