Item 1.01 Entry into a Material Definitive Agreement

On May 13, 2014, Equinix, Inc. (the “Company”) entered into amendment agreements (the “Amendment Agreements”) with each of Deutsche Bank AG, London Branch, JPMorgan Chase Bank, National Association, London Branch and Goldman, Sachs & Co. (the “Counterparties”) to amend the capped call transactions (the “Capped Call Transactions”) that the Company entered into with each of the Counterparties in connection with the issuance of the Company’s 4.75% Convertible Subordinated Notes (the “Notes”). The Amendment Agreements provide that, in lieu of the exchanges of the Notes, described in the Company’s Current Report on Form 8-K filed on May 13, 2014, constituting a termination event under the Capped Call Transactions with respect to a number of call options equal to the number of Notes, in denominations of $1,000 principal amount, being exchanged, such call options (the “Amended Call Options”) will instead remain outstanding. The Amended Call Options have substantially similar terms as the original call options except that (i) the Amended Call Options are European-style call options with an expiration date that corresponds to the maturity date of the Notes, (ii) each Counterparty may transfer its rights and obligations under, or in certain limited circumstances terminate all or a portion of, the Amended Call Options, if such Counterparty’s ownership of the Company’s common stock exceeds certain thresholds and (iii) in connection with any dilutive or concentrative event affecting the Company’s common stock, the cap price of the Amended Call Options shall be adjusted pursuant to standard, ISDA based provisions for over-the-counter equity options.

The foregoing description of the Amendment Agreements is a summary and is qualified in its entirety by the terms of the Amendment Agreements, copies of which will be filed as exhibits to the Company’s Form 10-Q for the quarter ending June 30, 2014.
