*Note: A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawn at any time.

Settlement Date: The closing will occur on April 1, 2026, which will be more than one U.S. business day after the date of this pricing term sheet. Under Rule 15c6-1 under the Securities Exchange Act of 1934, 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 senior notes on the date of pricing or the next five succeeding business days will be required, by virtue of the fact that the senior notes initially will settle in T+7, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisors.
