The Issuer has filed a registration statement (including a preliminary prospectus supplement and an accompanying prospectus) with the Securities and Exchange Commission ("SEC") for the offering to which this communication relates. Before you invest, you should read the prospectus in that registration statement and other documents that the Issuer has filed with the SEC, including the preliminary prospectus supplement, for more complete information about the Issuer and this offering. You may get these documents for free by visiting the SEC website at www.sec.gov. Alternatively, the Issuer, any underwriter or any dealer participating in the offering will arrange to send you the preliminary prospectus supplement and the accompanying prospectus if you request it by contacting Morgan Stanley & Co. LLC at 1-866-718-1649, BofA Securities, Inc. at 1-800-294-1322, J.P. Morgan Securities LLC collect at 1-212-834-4533 and SG Americas Securities, LLC, at 1-855-881-2108.

*The Issuer expects to deliver the Notes against payment for the Notes on or about August 18, 2026, which will be the tenth business day following the date of the pricing of the Notes (this settlement cycle being referred to as "T+10"). Under Rule 15c6-1 of the Exchange Act, 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 on the date of pricing will be required, by virtue of the fact that the Notes initially will settle in T+10, to specify alternative settlement arrangements to prevent a failed settlement.

**These Issuer ratings are not a recommendation to buy, sell or hold the Notes offered hereby. The ratings may be subject to revision or withdrawal at any time by the relevant rating agency. Each of the Issuer ratings included herein should be evaluated independently of any other Issuer rating.

Terms used but not defined herein shall have the meanings ascribed thereto in the Issuer's preliminary prospectus supplement, dated August 4, 2026, to the Issuer's prospectus, dated February 14, 2025.
