*Note: A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time.
**We expect that delivery of the notes will be made to investors on or about May 14, 2026, which is the third business day following the date of this final term sheet (such settlement being referred to as “T+3”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes earlier than the business day before May 14, 2026 will be required, by virtue of the fact that the notes initially will settle T+3, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement, and so should consult their own advisors.
