ABOUT THIS PROSPECTUS SUPPLEMENT

This prospectus supplement and the accompanying prospectus are each part of an automatic shelf registration statement on Form S-3 that we filed with the Securities and Exchange Commission (the “SEC”) as a “well-known seasoned issuer” as defined in Rule 405 of the Securities Act of 1933, as amended (the “Securities
Act”). Under the shelf registration process, we may from time to time offer and sell to the public any or all of the debt securities described in the registration statement in one or more offerings. This document is in two parts. The first
part, which is this prospectus supplement, describes the specific terms of the notes we are offering and other matters relating to us. The second part, which is the accompanying prospectus, gives more general information about the various securities
we may offer from time to time, some of which may not apply to the notes offered by this prospectus supplement. Generally when we refer to the “prospectus supplement,” we are referring to both parts combined. This prospectus supplement may
add to, update or change the information in the accompanying prospectus. To the extent there is a conflict between the information contained in this prospectus supplement, on the one hand, and the information contained in the accompanying prospectus
or any document incorporated by reference therein, on the other hand, you should rely on the information contained in this prospectus supplement.

We have not, and the underwriters have not, authorized anyone to provide any information other than that contained or incorporated by
reference in this prospectus supplement, the accompanying prospectus and any free writing prospectus prepared by or on behalf of us or to which we have referred you. We and the underwriters take no responsibility for, and can provide no assurance as
to the reliability of, any other information that others may give you. We are not, and the underwriters are not, making an offer of these securities in any jurisdiction where the offer or sale of such securities is not permitted. You should not
assume that the information contained in this prospectus supplement and the accompanying prospectus or any free writing prospectus prepared by or on behalf of us to which we have referred you is accurate on any date subsequent to the date set forth
on the front of the document or that any information we have incorporated by reference is correct on any date subsequent to the date of the document incorporated by reference, even though this prospectus supplement and the accompanying prospect
