writers expect to deliver the notes to investors through the book-entry delivery system of The Depository Trust Company and its direct participants, including Euroclear Bank and Clearstream, on or about May 1, 2025, which will be the third business day from the date of pricing of the notes (this settlement cycle is referred to as “T+3”). Under Rule 15c6-1under 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.
