About the Prospectus Supplement
This document consists of two parts. The first part is this prospectus supplement, which describes the specific terms of this common stock
offering and also adds to and updates the information contained or incorporated by reference in the accompanying prospectus. The second part is the prospectus, which describes more general information regarding our securities, some of which does not
apply to this offering. You should read both this prospectus supplement and the accompanying prospectus, together with additional information described under the heading Where You Can Find More Information in this prospectus supplement
and the accompanying prospectus. If the information set forth in this prospectus supplement differs in any way from the information set forth in the accompanying prospectus, the information contained in this prospectus supplement shall control.
In this prospectus supplement, as permitted by law, we incorporate by reference information from other documents that we file with
the Securities and Exchange Commission, or the SEC. This means that we can disclose important information to you by referring you to those documents. The information incorporated by reference is considered to be a part of this prospectus supplement
and should be read with the same care. When we update the information contained in documents that have been incorporated by reference by making future filings with the SEC, the information incorporated by reference in this prospectus supplement is
considered to be automatically updated and superseded. In other words, in case of a conflict or inconsistency between information contained in this prospectus supplement and information incorporated by reference into this prospectus supplement, you
should rely on the information contained in the document that was filed with the SEC later.
We and the underwriters have not authorized
anyone to provide any information other than that contained or incorporated by reference into this prospectus supplement or the accompanying prospectus or any relevant 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 or sale of notes in
any jurisdiction where the offer or sale is not permitted. You should assume that the information contained in or incorporated by reference into this prospectus supplement and the accompanying prospectus is accurate only as of the date appearing on
the front cover of this prospectus supplement or the date of the accompanying prospectus or the applicable incorporated document, regardless of the time of delivery of such document. Our business, financial condition, results of operations and
prospects may have changed since that date. It is important that you read and consider all of the information contained in or incorporated by reference into this prospectus supplement and the information contained in or incorporated by reference
into the accompanying prospectus in making your investment decision.
We are not, and the underwriters are not, making an offer to sell
these securities in any jurisdiction where the offer or sale is not permitted. Neither this prospectus supplement nor the accompanying prospectus constitute, and may not be used in connection with, an offer to sell, or a solicitation of an offer to
buy, any securities offered by this prospectus supplement by any person in any jurisdiction in which it is unlawful for such person to make such an offer or solicitation. You must comply with all applicable laws and regulations in force in any
applicable jurisdiction and you must obtain any consent, approval or permission required by you for the purchase, offer or sale of the common stock under the laws and regulations in force in the jurisdiction to which you are subject or in which you
make your purchase, offer or sale, and neither we nor the underwriters will have any responsibility therefor.
We reserve the right to
withdraw this offering of our common stock at any time. We and the underwriters also reserve the right to reject any offer to purchase, in whole or in part, for any reason, or to sell less than the amount of common stock offered hereby.
References to Equinix, the Company, we, our and us and similar terms mean Equinix,
Inc., a Delaware corporation, and its consolidated subsidiaries, unless the context otherwise requires.
