February 11, 2025 (T+5)

We expect that delivery of the Notes will be made to investors on or about February 11, 2025, which will be the fifth business day following the date of this pricing supplement (such settlement being referred to as “T+5”). Under Rule 15c6-1 under the Exchange Act, 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 prior to the business day before the settlement date will be required, by virtue of the fact that the Notes initially will settle in T+5, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisors.
