#### United States Holders

#### Gains Upon Disposition
In the case of a sale or other disposition (including a retirement) of a Series 2025B Junior Subordinated Note, a United States Holder will generally recognize gain or loss equal to the difference, if any, between the amount received (other than any amount representing accrued but unpaid interest, which will be treated as interest income to the extent not previously included in income) and the United States Holder’s adjusted tax basis in the Series 2025B Junior Subordinated Note.

A gain or loss recognized by a United States Holder on a sale or other disposition of a Series 2025B Junior Subordinated Note generally will constitute capital gain or loss. Capital gains recognized by a non-corporate United States Holder upon the sale or other disposition of a Series 2025B Junior Subordinated Note that is held for more than one year are generally eligible for reduced rates of United States federal income taxation. The ability of a United States Holder to deduct capital losses is limited.

Each United States Holder that is an individual, estate or trust is urged to consult its tax advisors regarding the applicability of this Medicare tax to its income and gains in respect of its investment in the Series 2025B Junior Subordinated Notes.

#### Backup Withholding and Information Reporting
Information reporting requirements generally apply in connection with payments on the Series 2025B Junior Subordinated Notes to, and the proceeds from a sale or other disposition of the Series 2025B Junior Subordinated Notes by, non-corporate United States Holders. A United States Holder will be subject to a backup withholding tax on these payments if the United States Holder fails to provide its taxpayer identification number to the paying agent and fails to comply with certain certification procedures or otherwise establish an exemption from backup withholding. Any backup withholding from a payment to a United States Holder will be allowed as a credit against such United States
