The issuer has filed a registration statement (including a base prospectus) and the Preliminary Prospectus Supplement (including such base prospectus) with the SEC for the offering of the Notes to which this communication relates (File No. 333-287024). Before you invest, you should read the Preliminary Prospectus Supplement (including such base prospectus) and any other documents the issuer has filed with the SEC for more complete information about the issuer and the offering of the Notes. You may get these documents for free by searching the SEC online database (EDGAR) on the SEC website at http://www.sec.gov. Alternatively, the issuer, any underwriter or any dealer participating in the offering of the Notes will arrange to send you the Preliminary Prospectus Supplement (including such base prospectus) if you request it by calling BMO Capital Markets Corp. toll-free at 1-888-200-0266, J.P. Morgan Securities LLC collect at 1-212-834-4533, Mizuho Securities USA LLC toll-free at 1-866-271-7403 or U.S. Bancorp Investments, Inc. toll-free at 1-877-558-2607.

This communication should be read in conjunction with the Preliminary Prospectus Supplement (including such base prospectus). The information in this communication supersedes the information in the Preliminary Prospectus Supplement (including such base prospectus) to the extent inconsistent with the information therein.

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

\*\* It is expected that delivery of the Notes will be made against payment for the Notes on or about February 9, 2026, which is the third business day following the date of this pricing term sheet (such settlement cycle being referred to as "T+3"). Under Rule 15(c)6-1 under the Securities Exchange Act of 1934, trades in the secondary market generally 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 on any date prior to the first business day before delivery will be required, by virtue of the fact that the Notes initially will settle in T+3, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement. Purchasers of the Notes who wish to trade the Notes on any date prior to the first business day before delivery should consult their own advisors.
