Wall Street was looking for AFFO per share of $4.80 on revenue of $1.19 billion, so Equinix slightly beat both expectations.

For full-year 2017, year-over-year revenue increased 22% -- 11% on a normalized and constant currency basis -- to $4,368 million, and AFFO per share grew 22% to 18.5. Revenue slightly exceeded the higher end of the updated guidance range that Equinix provided last quarter ($4,355 million to $4,363 million).

What happened with Equinix in the quarter?

  • Recurring revenue, consisting primarily of colocation, interconnection, and managed services, rose 26% year over year to $1,123 million. Nonrecurring revenue jumped 55% to $77.6 million.
  • The enterprise vertical's revenue grew twice as fast as revenue generated from any other vertical. Equinix's customers include 46% of the Fortune 500 and one-third of the Forbes Global 2000 companies.
  • Equinix increased its global reach via two acquisitions, one in Q4 2017 and the other in early Q1 2018. In December, the company announced a $791 million agreement to acquire Australian data center provider Metronode, which will add 10 data centers and four new metro regions to existing Equinix operations in the country. Along with the earnings release on Wednesday, the company announced the $800 million acquisition of Infomart Dallas, which it touts is one of the most connected facilities in the United States. 
  • The company also continues to expand its reach through organic expansion, with 30 projects now underway, half of which are in the Europe, Middle East, and Africa (EMEA) region. On Wednesday, new expansions were announced for the Culpeper, Virginia; Houston; Washington, D.C; Silicon Valley; London; Paris; Sao Paulo; and Sofia, Burgaria regions totaling more than $500 million of capital expenditures.
  • Equinix revealed the expansion of Equinix Internet Exchange to nine new metros in the EMEA and Americas regions.
  • It disclosed the future introduction of services intended to enable customers to rapidly scale their digital businesses. As part of this initiative, Equinix is physically and virtually connecting its global data centers, enabling customers to discover and connect to any other Equinix customer. Services are delivered through Equinix Cloud Exchange Fabric. 

Here's what Peter Van Camp, executive chairman and interim CEO, had to say:  

In addition to strong financial performance, Equinix achieved a number of significant milestones around interconnection, innovation and acquisitions in 2017 that add even more value to our role as a strategic partner to companies in the execution of their digital business strategies. As we approach our 20th anniversary and reflect on what we've built, we believe our platform will become even more important for our customers in the years to come. We have a clear vision of our strategy and the opportunities ahead, and we are looking forward to another successful year.

Van Camp was Equinix's CEO from 2000 to 2007. Equinix is actively seeking a new leader, as former CEO Steve Smith resigned from his position, along with his seat on the board of directors, in late January after "exercising poor judgment with respect to an employee matter," according to Equinix. 

Looking ahead

Equinix provided first-quarter and full-year 2018 guidance. Guidance excludes the anticipated contributions from the Metronode and Infomart Dallas acquisitions. For the first quarter, it expects revenue in the range of $1,204 million to $1,212 million, which at the midpoint represents an increase of 27.2% over the year-ago quarter. Equinix does not issue quarterly AFFO guidance.
