ure does not limit the amount of debt securities we may issue under it, and it provides that
additional debt securities of any series may be issued up to the aggregate principal amount that we may authorize from time to time. As of December 31, 2024, approximately $7.3 billion aggregate principal amount of debt securities were
issued and outstanding under the indenture. At the date of this prospectus, since December 31, 2024, we have issued $1.1 billion aggregate principal amount of debt securities.

Principal and any premium and interest in respect to the debt securities will be payable, and the debt securities will be transferable, at the
corporate trust office of the trustee, unless we specify otherwise in the applicable prospectus supplement. At our option, however, payment of interest may be made by check mailed to the registered holders of the debt securities at their registered
addresses.

We will describe material U.S. federal income tax and other considerations relating to debt securities denominated in
foreign currencies or units of two or more foreign currencies in the applicable prospectus supplement.

Unless we otherwise specify in
this prospectus or in the applicable prospectus supplement, we will issue debt securities in the form of global securities, deposited with and registered in the name of The Depository Trust Company, as depositary, which we refer to as
“DTC,” or its nominee. Interests in the debt securities will be shown on, and transfers thereof will be effected only through, records maintained by DTC and its participants. See “Book-Entry Securities.”
