*We expect that delivery of the Notes will be made against payment therefor on November 10, 2025, which will be the third business day following the date of pricing of the Notes (such settlement cycle being referred to as "T+3"). Under Rule 15c6-1 promulgated 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 a trade expressly agree otherwise. Accordingly, purchasers who wish to trade Notes prior to the business day preceding the date of delivery may be required, by virtue of the fact that the Notes initially will settle in T+3, to specify alternative settlement arrangements to prevent a failed settlement. Such purchasers should consult their own advisors.

**These ratings are not a recommendation to buy, sell or hold the Notes. The ratings may be subject to revision or withdrawal at any time by the relevant rating agency. Each of the ratings included herein should be evaluated independently of any other rating. No report of any rating agency is incorporated by reference herein.

The Notes will be represented by beneficial interests in fully registered permanent global notes (the "global notes"), which will be registered in the name of a nominee of, and shall be deposited on or about November 10, 2025 with, a common depositary for, and in respect of interests held through, Euroclear Bank, S.A./N.V., as operator of the Euroclear System ("Euroclear"), and Clearstream Banking, société anonyme ("Clearstream"). Any Notes represented by global notes held by a nominee of Euroclear or Clearstream will be subject to the then applicable procedures of Euroclear and Clearstream, as applicable. Euroclear and Clearstream's current practice is to make payments in respect of global notes to participants of record that hold an interest in the relevant global notes at the close of business (in London) on the date that is the clearing system business day (for these purposes, a day on which Euroclear and Clearstream are open for business) immediately preceding each applicable interest payment date.
