Plus accrued interest, if any, from September 14, 2026, if settlement occurs after that date.

We intend to apply to list each series of the notes on the Nasdaq Bond Exchange (“Nasdaq”). The listing applications will be subject to approval by Nasdaq. We currently expect trading in each series of the notes on Nasdaq to begin within 30 days after the original issue date. If such a listing is obtained, we have no obligation to maintain such listing and we may delist any series of the notes at any time. Currently, there is no public market for any series of the notes.

The underwriters expect to deliver the notes on or about September 14, 2026 only in book-entry form through a common depositary of Clearstream Banking, S.A. (“Clearstream”) or Euroclear Bank S.A./N.V. (“Euroclear” and, together with Clearstream, the “clearing systems”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), trades in the secondary market are generally required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on any day prior to the business date before delivery will be required, by virtue of the fact that the notes initially settle in T+3, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement and should consult their own advisors. See “Underwriting.”
