The term “Treasury Rate” has the meaning ascribed to that term in the Issuer’s Preliminary Prospectus Supplement, dated September 14, 2026.
| * | The underwriters expect to deliver the notes in book-entry form only through the facilities of The Depository Trust Company against payment in New York, New York on or about the second business day following the date of the prospectus supplement, or “T+2”. Trades of securities in the secondary market generally are required to settle in one business day, referred to as T+1, unless the parties to a trade agree otherwise. Accordingly, by virtue of the fact that the initial delivery of the notes will not be made on a T+1 basis, investors who wish to trade the notes prior to the first business day before delivery of the notes will be required to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement. Investors in the notes who wish to trade the notes on any date prior to the first business day before delivery should consult their own advisors. |
