Equinix Receives Favorable REIT Private Letter Ruling from the IRS

REDWOOD CITY, Calif., May 20, 2015 /PRNewswire/ -- Equinix, Inc. (Nasdaq: EQIX), the global interconnection and data center company, today announced that the U.S. Internal Revenue Service ("IRS") has issued a favorable private letter ruling ("PLR") in connection with Equinix's conversion to a real estate investment trust ("REIT") for federal income tax purposes effective for its taxable year commencing January 1, 2015. The PLR supports Equinix's position with respect to numerous technical tax issues in connection with Equinix's election of REIT status and conversion to a REIT. In the PLR, the IRS addressed and favorably ruled on Equinix's assets and revenue model (including data center assets as qualified REIT assets and interconnection revenues as qualified REIT revenues), its particular items of federal taxable income from global operations, and its transition plans from a C-corporation to a REIT (including proposed distributions to stockholders). In accordance with the previously announced unanimous approval of Equinix's conversion to a REIT by the Board of Directors of Equinix, Equinix began its first day as a REIT on January 1, 2015.

"Equinix is excited to have received a favorable PLR," said Steve Smith, president and CEO of Equinix. "We are pleased with our current business momentum, and the REIT structure positions us well to provide world-class facilities and services to our customers through Platform Equinix, and to deliver global profitable growth while creating increased shareholder return as we scale our business."
