____________

\* An explanation of the significance of ratings may be obtained from the ratings agencies. Generally, ratings agencies base their ratings on such material and information, and such of their own investigations, studies and assumptions, as they deem appropriate. The security ratings above are not a recommendation to buy, sell or hold the securities offered hereby. The ratings may be subject to review, revision, supervision, reduction or withdrawal at any time by Moody's or Standard & Poor's. Each of the security ratings above should be evaluated independently of any other security rating.

\*\* We currently expect to deliver the notes on or about March 2, 2026, 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 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), trades in the secondary market generally are required to settle in one business day (as such term is used for purposes of Rule 15c6-1 of the Exchange Act) unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on any date prior to the business day before delivery of the notes will be required, by virtue of the fact that the notes will settle in T+3, to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement; such purchasers should consult their own advisors in this regard.

The issuer has filed a registration statement (including a prospectus) with the SEC for the offering to which this communication relates. Before you invest, you should read the prospectus in that registration statement, the preliminary prospectus supplement and other documents the issuer has filed with the SEC for more complete information about the issuer and this offering. You may get these documents for free by visiting EDGAR on the SEC Web site at www.sec.gov. Alternatively, the issuer, any underwriter or any dealer participating in the offering will arrange to send you the prospectus and the preliminary prospectus supplement if you request it by calling Citigroup Global Markets Inc. at 1-800-831-9146, Deutsche Bank Securities Inc. at 1-800-503-4611, BofA Securities, Inc. at 1-800-294-1322, J.P. Morgan Securities LLC at 1-212-834-4533 or Wells Fargo Securities, LLC at 1-800-645-3751.
