Overview

Equinix, Inc. connects more than 4,800 companies directly to their customers and partners inside the world’s most networked data centers. Today, businesses leverage the Equinix interconnection platform in 33 strategic markets across the Americas, Asia-Pacific, and Europe, Middle East and Africa (EMEA).

Platform Equinix^® combines a global footprint of state-of-the-art International Business Exchange™ (IBX^®) data centers, a variety of interconnection opportunities and unique ecosystems. Together these components accelerate business growth and opportunity for Equinix’s customers by safekeeping their infrastructure and applications closer to users, enabling them to improve performance with cost-effective and scalable interconnections, work with vendors to deploy new technologies such as cloud computing and to collaborate with the widest variety of partners and customers to achieve their ambitions.

Equinix’s platform offers these unique value propositions to customers:

Table of Contents

Equinix has established a critical mass of customers that continues to drive new and existing customer growth and bookings. Our network- and cloud-neutral business model also contributes to our success in the market. We offer customers direct interconnection to an aggregation of bandwidth providers, rather than focusing on selling a particular network. The providers in our sites include the world’s top carriers, Internet service providers (ISPs), broadband access networks (DSL / cable) and international carriers. Neutrality also means our customers can choose to buy from, or partner with, leading companies across our five targeted verticals. These include:

Equinix generates revenue by providing colocation and related interconnection and managed IT infrastructure offerings on a global platform of 100+ IBX data centers.

The market for Equinix’s offerings has historically been served by large telecommunications carriers that have bundled their telecommunications and managed services with their colocation offerings. In addition, some Equinix customers, such as Microsoft, build and operate their own data centers for their large infrastructure deployments, called server farms. However, these customers rely upon Equinix IBX data centers for many of their critical interconnection relationships. The need for large, wholesale, outsourced data centers is also being addressed by providers that build large data centers to meet customers’ needs for standalone data centers, a different customer segment than Equinix serves.

Due to the increasing cost and complexity of the power and cooling requirements of today’s data center equipment, Equinix has gained many customers that have outgrown their existing data centers or have realized the benefits of a network-neutral model and the ability to create their own optimized business ecosystems for the exchange of data. Strategically, we will continue to look at attractive opportunities to grow market share and selectively expand our footprint and offerings. We continue to leverage our global reach and depth to differentiate Equinix based upon our ability to support truly global customer requirements in all our markets.

Several factors contribute to the growth in demand for data center offerings, including:

Industry Background

The Internet is a collection of numerous independent networks interconnected to form a network of networks. Users on different networks are able to communicate with each other through interconnection between these networks. For example, when a person sends an email to someone who uses a different provider for his or her connectivity (e.g. Comcast versus Verizon), the email must pass from one network to the other to get to its final destination. Equinix provides a physical point at which that interconnection can occur.

To accommodate the rapid growth of Internet traffic, an organized approach for network interconnection was needed. This was the start of the network era, when networks gained mutual advantage by exchanging data traffic on interoperable platforms. The exchange of traffic between these networks became known as peering. Peering is when networks trade traffic at relatively equal amounts and set up agreements to trade traffic often at no charge to the other party. At first, government and non-profit organizations established places where these networks could exchange traffic, or peer, with each other—these points were known as network access points, or NAPs. Over time, many NAPs became a natural extension of carrier services and were run by such companies as MFS (now a part of Verizon Business), Sprint, Ameritech and Pacific Bell (the last two now parts of AT&T).

Ultimately, these NAPs were unable to scale with the growth of the Internet, and the lack of “neutrality” by the carrier owners of these NAPs created a conflict of interest with the participants. This created a market need for network-neutral interconnection points that could accommodate the rapidly growing need to increase performance for enterprise and consumer users of the Internet, especially with the rise of important content providers such as AOL, Microsoft, Yahoo! and others. In addition, the providers, as well as a growing number of enterprises, required a more secure and reliable solution for direct connection to a variety of telecommunications networks, as the importance of their Internet operations continued to grow. These were the seeds of the connected era, when peering expanded exponentially, and between new players, and access to information anytime and anywhere became the norm.

To accommodate Internet traffic growth, the largest networks left the NAPs and began connecting and trading traffic by placing private circuits between each other. Peering, which once occurred at the NAP locations, was moved to these private circuits. Over the years, these circuits became expensive to expand and could not be built quickly enough to accommodate traffic growth. This led to a need by the large carriers to find a more

efficient way to peer. Today, many customers satisfy their requirements for peering through data center providers like Equinix because it permits them to peer with the networks they require within one location, using simple direct connections. Their ability to peer within a data center or across a data center campus, instead of across a metro area, has increased the scalability of their operations while decreasing network costs.

The interconnection model has further evolved over the years to include new offerings as the increasingly collaborative landscape of the interconnected era imposes new demands on connectivity. As enterprises become increasingly interdependent and cloud-enabled, they need real-time data exchange and reliable, instant connections between the various corners of any given digital ecosystem to compete. Starting with the peering and network communities, interconnection has been used for new network services including carrier Ethernet, multiprotocol label switching (MPLS), virtual private networks (VPNs) and mobile services, in addition to traditional international private line and voice services. The industry continues to evolve with a set of new offerings where interconnection is often used to solve the network-to-network interconnection challenges.

In addition, the enterprise customer segment is also evolving. In the past, most enterprises opted to keep their data center requirements in house. However, current trends are leading more and more enterprise CIOs to either outsource their data center requirements, and/or extend their corporate wide area networks (WANs) into carrier-neutral colocation facilities. The combination of globalization, the proliferation of bandwidth intensive Internet-facing applications and rich media content, the need to provide access to cloud computing environments, business continuity and disaster recovery needs, plus tight corporate IT budgets mean that enterprise CIOs must do more with less. Industry analysts forecast growth in the colocation market to be approximately 10% per year over the next four years.

Equinix Value Proposition

More than 4,800 companies, including a diversified mix of cloud and IT service providers, content providers, enterprises, financial companies, and network and mobile service providers, currently operate within Equinix IBX data centers. These companies derive specific value from the following elements of the Equinix service offering:

Our Strategy

Our objective is to expand our global leadership position as the premier network- and cloud-neutral data center platform for cloud and IT services providers, content providers, financial companies, enterprises and network and mobile services providers. Key components of our strategy include the following:

Improve customer performance through interconnection. We have assembled a critical mass of premier network providers and content companies and have become one of the core hubs of the information-driven world. This critical mass is a key selling point for companies that want to connect with a diverse set of networks to provide the best connectivity to their end customers and network companies that want to sell bandwidth to companies and interconnect with other networks in the most efficient manner available. Currently, we house more than 1,000 unique networks, including all of the top tier networks, allowing our customers to directly interconnect with providers that best meet their unique global and regional price and performance needs. We have a growing mass of key players in cloud and IT services, such as Accenture, Amazon Web Services, AT&T, Microsoft Azure and Salesforce.com, and in the enterprise and financial sectors, such as Bechtel, Bloomberg, Chicago Board of Trade, The GAP, McGraw-Hill, and others. We expect these segments will continue to grow as they seek to leverage our critical mass of network providers and interconnect directly with each other to improve performance.

Streamline ease of doing business globally. Data center reliability, power availability and network choice are the most important attributes considered by our customers when they are choosing a data center provider in a particular location. We have long been recognized as a leader in these areas and our performance continues to improve against these criteria. Our power infrastructure delivered 99.9999% uptime globally in 2014.

In 2014, more than half of our revenue came from customers with deployments across two or more of our global regions, and as globalization continues, seamless global solutions will become an increasingly important data center selection criteria. We continue to focus on strategic acquisitions to expand our market coverage and on global product standardization, pricing and contracts harmonization initiatives to meet these global demands.

Deepen existing and grow new ecosystems. As networks, cloud and IT services providers, content providers, financial services providers and enterprises locate in our IBX data centers, it benefits their suppliers and business partners to do so as well, to gain the full economic and performance benefits of direct interconnection for their business ecosystems. These partners, in turn, pull in their business partners, creating a “network effect” of customer adoption. Our interconnection offerings enable scalable, reliable and cost-effective interconnectivity and optimized traffic exchange, thus lowering overall cost and increasing flexibility. The ability to directly interconnect with a wide variety of companies is a key differentiator for us in the market and enables companies to create new opportunities within unique ecosystems by working together. We have efficient and innovative Internet, Ethernet and Cloud Exchange platforms to accelerate commercial growth within the ecosystems in our IBX sites via this network effect.

Expand vertical go-to-market plan. We plan to continue to focus our go-to-market efforts on customer segments and business applications that appreciate the Equinix value proposition of interconnection, reliability, global reach and ecosystem collaboration opportunities. Today we have identified these segments as cloud

services, content and digital media, financial services, enterprises, IT services, and network and mobile service providers. As digital business evolves, we will continue to identify and focus our go-to-market efforts on industry segments that need our value proposition.

Accelerate global reach and scale. We continue to evaluate expansion opportunities in select markets based on customer demand. In 2013, we acquired the Kleyer 90 carrier hotel in Frankfurt to consolidate our position in one of Europe’s key communications hubs. We entered the Osaka, Japan market with a new data center that provides geographic redundancy within the Japanese market. We also added capacity across our global footprint with a second data center in Seattle, an eleventh in Northern Virginia, a fifth in Zurich, a fourth in Tokyo and a major expansion in Singapore. In 2014, we completed the acquisition of ALOG Data Centers of Brazil S.A. and took the remaining ownership interest of the four data centers at ALOG, including two in São Paulo and two in Rio de Janeiro.

Our strategy is to continue to grow in select existing markets and possibly expand to additional markets where demand and financial return potential warrant. We expect to execute this expansion strategy in a cost-effective and disciplined manner through a combination of acquiring existing data centers through lease or purchase, acquiring or investing in local data center operators and building new IBX data centers based on key criteria, such as demand and potential financial return, in each market.

Our Offerings

Equinix provides a choice of data center offerings primarily comprised of colocation, interconnection solutions and managed IT infrastructure services.

Colocation and Related Offerings

Our IBX data centers provide our customers with secure, reliable and fault-tolerant environments that are necessary for optimum Internet commerce interconnection. Many of our IBX data centers include multiple layers of physical security, scalable cabinet space availability, on-site trained staff (24x7x365) dedicated areas for customer care and equipment staging, redundant AC/DC power systems and other redundant and fault-tolerant infrastructure systems. Some specifications of offerings provided may differ based on original facility design or market.

Within our IBX data centers, customers can place their equipment and interconnect with a choice of networks, cloud providers or other business partners. We also provide customized solutions for customers looking to package our IBX offerings as part of their complex solutions. Our colocation offerings include:

Cabinets. Our customers have several choices for colocating their networking, server and storage equipment. They can place the equipment in one of our shared or private cages or customize their space. In certain select markets, customers can purchase their own private “suite” which is walled off from the rest of the data center. As customers’ colocation requirements increase, they can expand within their original cage (or suite) or upgrade into a cage that meets their expanded requirements. Customers buy the hardware they place in our IBX data centers directly from their chosen vendors. Cabinets (or suites) are priced with an initial installation fee and an ongoing recurring monthly charge.

Power. Power is an element of increasing importance in customers’ colocation decisions. We offer both AC and DC power circuits at various amperages and phases customized to a customer’s individual power requirements. We also offer metered power in certain markets. Power is priced with an initial installation fee and an ongoing recurring monthly charge.

IBXflex. IBXflex allows customers to deploy mission-critical operations personnel and equipment on-site at our IBX data centers. Because of the close proximity to their infrastructure within our IBX data centers, IBXflex customers can offer a faster response and quicker troubleshooting solution than those available in traditional colocation facilities. This space can also be used as a secure disaster recovery point for customers’ business and operations personnel. This service is priced with an initial installation fee and an ongoing recurring monthly charge.

Interconnection Solutions

Our interconnection solutions enable scalable, reliable and cost-effective interconnection and traffic exchange between Equinix customers. These interconnection solutions are either on a one-to-one basis with direct cross connects or one-to-many through one of our Equinix Exchange solutions. In the peering community, we provide an important industry leadership role by acting as the relationship broker between parties who would like to interconnect within our IBX data centers. Our staff holds or has held significant positions in many leading industry groups, such as the North American Network Operators’ Group, or NANOG, and the Internet Engineering Task Force, or IETF. Members of our staff have published industry-recognized white papers and strategy documents in the areas of peering and interconnection, many of which are used by other institutions worldwide in furthering the education and promotion of this important set of solutions. We expect to continue to develop additional solutions in the area of traffic exchange that will allow our customers to leverage the critical mass of networks, cloud services providers, and many important financial services and e-commerce industry leaders now available in our IBX data centers. Our current exchange solutions are comprised of the following:

Physical Cross Connect/Direct Interconnections. Customers needing to directly and privately connect to another IBX data center customer can do so through single or multi-mode fiber. These cross connections are the physical link between customers and can be implemented within 24 hours of request. Cross-connect offerings are priced with an initial installation fee and an ongoing monthly recurring charge.

Table of Contents

Equinix Internet Exchange. Customers may choose to connect to and peer through the central switching fabric of our Equinix Internet Exchange rather than purchase a direct physical cross connection. With a connection to this switch, a customer can aggregate multiple interconnects over one physical connection with up to multiple, linked 10 gigabit ports of capacity instead of purchasing individual physical cross connects. The offering is priced per IBX data center with an initial installation fee and an ongoing monthly recurring charge. Individual IBX data center prices increase as the number of participants on the exchange service grows.

Equinix Metro Connect. Customers who are located in one IBX data center may need to interconnect with networks or other customers located in an adjacent or nearby IBX data center in the same metro area. Metro Connect allows customers to seamlessly interconnect between IBX data centers at capacities up to an OC-192, or 10 gigabits per second level. Metro Connect offerings are priced with an initial installation fee and an ongoing monthly recurring charge dependent on the capacity purchased by the customer.

Internet Connectivity Services. Customers who are installing equipment in our IBX data centers generally require IP connectivity or bandwidth services. Although many large customers prefer to contract directly with carriers, we offer customers the ability to contract for these services through us from any of the major bandwidth providers in that data center. This service, which is provided in our Asia-Pacific and EMEA regions, is targeted to customers who require a single bill and a single point of support for their entire contract through Equinix for their bandwidth needs. Internet connectivity services are priced with an initial installation fee and an ongoing monthly recurring charge based on the amount of bandwidth committed.

Ethernet Exchange Services. The Ethernet Exchange offering is similar to the Equinix Internet Exchange, and we offer it in 17 markets so that customers can connect via a central switching fabric to interconnect between multiple Carrier Ethernet Providers rather than creating individual network-to-network interfaces (NNIs) between individual carriers. The offering builds on the benefits of the Internet community and extends the ability to interconnect to the high growth Ethernet industry. The offering is priced per IBX data center with an initial fee and a monthly recurring charge.

Equinix Cloud Exchange. The Equinix Cloud Exchange is an advanced interconnection solution that enables seamless, on-demand, direct access to multiple clouds from multiple networks around the world. Cloud Exchange provides virtualized, private direct connections that bypass the Internet to provide better security and performance with a range of bandwidth options. It enables businesses to connect to many participants (clouds, networks, enterprise customers) over a single physical port, enabling dynamic bandwidth allocation among various parties. The Equinix Cloud Exchange Portal and APIs simplify the process of provisioning and managing connections to multiple cloud services and networks. Equinix Cloud Exchange offerings are priced with an initial installation fee and an ongoing monthly recurring charge dependent on the capacity purchased by the customer.

Equinix Performance Hub™. The Equinix Performance Hub enables companies to securely and directly connect to leading public clouds, easily deploy a private cloud, and lay the foundation of a hybrid cloud. Performance Hub solutions are extensions of companies’ IT network that reside within Equinix data centers. An Equinix Performance Hub places corporate IT resources near large user populations in IBX data centers connected to many networks and clouds. Performance Hub solutions can be implemented gradually, without closing or moving out of existing data centers. This distributed, connectivity-driven approach to data center computing has been proven by Gartner, 451 Group, and many enterprise customers to provide dramatic benefits in application and network performance, as well as in business and IT agility. The Performance Hub offering is priced per IBX data center with an initial installation fee and an ongoing recurring monthly charge.

Managed IT Infrastructure Services

With the continued growth in Internet traffic, networks, cloud providers, service providers, enterprises and content providers are challenged to deliver fast and reliable service, while lowering costs. With more than 1,000 network service providers, Internet Service Providers (ISPs) and fixed and mobile carriers and 500+ cloud

Sales and Marketing

Sales. We use a direct sales force and channel marketing program to market our offerings to global enterprises, content providers, financial companies, and mobile and network service providers. We organize our sales force by customer type as well as by establishing a sales presence in diverse geographic regions, which enables efficient servicing of the customer base from a network of regional offices. In addition to our worldwide headquarters located in Silicon Valley, we have established an Asia-Pacific regional headquarters in Hong Kong, and a European regional headquarters in Amsterdam. Our Americas sales offices are located in Boston, Chicago, Los Angeles, New York, Reston, Virginia, Silicon Valley and Toronto and sales offices in Brazil operate out of data centers in Sao Paulo and Rio de Janeiro. Our EMEA sales offices are located in Amsterdam, Dubai, Dusseldorf, Enschede, Frankfurt, Geneva, London, Munich, Paris, Zurich and Zwolle. Our Asia-Pacific sales offices are located in Beijing, Hong Kong, Jakarta, Seoul, Shanghai, Singapore, Sydney, Melbourne and Tokyo.

Our sales team works closely with each customer to foster the natural network effect of our IBX model, resulting in access to a wider potential customer base via our existing customers. As a result of the IBX interconnection model, IBX data center participants often encourage their customers, suppliers and business partners to also locate in our IBX data centers. These customers, suppliers and business partners, in turn, encourage their business partners to locate in our IBX data centers resulting in additional customer growth. This network effect significantly reduces our new customer acquisition costs. In addition, large network providers, cloud providers or managed service providers may refer customers to Equinix as a part of their total customer solution. Equinix also

focuses vertical sales specialists selling to support specific industry requirements for network, mobile and content providers, financial services, cloud computing, systems integrators and enterprise customer segments.

Marketing. To support our sales efforts and to actively promote our brand in the Americas, Asia-Pacific and EMEA, we conduct comprehensive marketing programs. Our marketing strategies include active public relations and ongoing customer communications programs. Our marketing efforts are focused on major business and trade publications, online media outlets, industry events and sponsored activities. Our staff holds leadership positions in key networking organizations, and we participate in a variety of Internet, Carrier Ethernet, computer and financial industry conferences, placing our officers and employees in keynote speaking engagements at these conferences. We also regularly measure customer satisfaction levels and host key customer forums to ensure customer needs are understood and incorporated in product and service planning efforts. From a brand perspective, we build recognition through our website, sponsoring or leading industry technical forums, participating in Internet industry standard-setting bodies and through advertising and online campaigns. We continue to develop and host industry educational forums focused on peering technologies and practices for ISPs and content providers.

Our Competition

While a large number of enterprises own their own data centers, many others outsource some or all of their requirements to multitenant Internet data center facilities, such as those operated by Equinix. We believe that the outsourcing trend is likely to not only continue but also to grow in the coming years. It is estimated that Equinix is one of over 650 companies that provide Internet data center offerings around the world, ranging in size from firms with a single data center in a single market to firms in over 20 markets. Equinix competes with these firms, which vary in terms of their data center offerings, including:

Colocation Providers

Colocation data centers are a type of Internet data center that can also be referred to as “retail” data center space. Typically, colocation data center space is offered on the basis of individual racks/cabinets or cages ranging from 500 to 10,000 square feet in size. Typical customers of colocation providers include:

Full facility maintenance and systems, including fire suppression, security, power backup and HVAC, are routinely included in managed colocation offerings. A variety of additional services are typically available, including remote hands technician services and network monitoring services.

In addition to Equinix, providers that offer colocation both globally and locally include firms such as AT&T, CenturyLink, COLT, CyrusOne, Level 3 Communications, NTT and Verizon Business.

Carrier-Neutral Colocation Providers

In addition to data center space and power, colocation providers also offer interconnection. Certain of these providers, known as network or carrier-neutral colocation providers, can offer customers the choice of hundreds of network service providers or ISPs to choose from. Typically, customers use interconnection to buy Internet

connectivity, connect to VoIP telephone networks, perform financial exchange and settlement functions or perform business-to-business e-commerce. Carrier-neutral data centers are often located in key network hubs around the world like New York, Ashburn, Virginia, London, Amsterdam, Singapore and Hong Kong. Two types of data center facilities offering carrier-neutral colocation are used for many network-to-network interconnections:

In addition to Equinix, other providers that we believe could be defined as offering carrier-neutral colocation include CoreSite, Global Switch, Interxion, Telecity Group, Telehouse and Telx.

Wholesale Data Center Providers

Wholesale data center providers lease data center space that is typically offered in cells or pods (i.e., individual white-space rooms) ranging in size from 10,000 to 20,000 square feet, or larger. Wholesale data center offerings are targeted to both enterprises and to colocation providers. These data centers primarily provide space and power without additional services like technicians, remote hands services or network monitoring (although other tenants might offer such services).

Sample wholesale data center providers include Digital Realty Trust, DuPont Fabros Technology, e-Shelter and Global Switch.

Managed Hosters

Managed hosting services are provided by several firms that also provide data center colocation services. Typically, managed hosting providers can manage server hardware that is owned by either the hosting provider or the customer. They can also provide a combination of comprehensive systems administration, database administration and sometimes application management services. Frequently, this results in managed hosting providers “running” the customer’s servers, although such administration is frequently shared. The provider may manage such functions as operating systems, databases, security and patch management, while the customer will maintain management of the applications riding on top of those systems.

The full list of potential services that can be offered as part of managed hosting is substantial and includes services such as remote management, custom applications, helpdesk, messaging, databases, disaster recovery, managed storage, managed virtualization, managed security, managed networks and systems monitoring. Managed hosting services are typically used for:

Examples of managed hosters include AT&T, CenturyLink, NaviSite, Rackspace, SunGard, Verizon Business and Verizon Terremark.

Table of Contents

Unlike other providers whose core businesses are bandwidth or managed services, we focus on neutral interconnection hubs for cloud and IT service providers, content providers, financial companies, enterprises and network service providers. As a result, we do not have the limited choices found commonly at other hosting/colocation companies. We compete based on the quality of our IBX data centers, our ability to provide a one-stop global solution in our Americas, EMEA and Asia-Pacific locations, the performance and diversity of our network- and cloud-neutral strategy, and the economic benefits of the aggregation of top network, cloud and business ecosystems under one roof. We expect to continue to benefit from several industry trends including the need for contracting with multiple networks due to the uncertainty in the telecommunications market; customers’ increasing power requirements; enterprise customers’ increased use of virtualization and outsourcing; the continued growth of broadband and significant growth in Ethernet as a network alternative; and the growth in mobile applications.

We currently operate in three reportable segments comprised of our Americas, EMEA and Asia-Pacific geographic regions. Information attributable to each of our reportable segments is set forth in Note 16 of Notes to Consolidated Financial Statements in Item 8 of this Annual Report on Form 10-K.

Employees

As of December 31, 2014, we had 3,866 employees. We had 2,122 employees based in the Americas, 1,023 employees based in EMEA and 721 employees based in Asia-Pacific. Of those employees, 1,756 were in engineering and operations, 802 were in sales and marketing and 1,308 were in management, finance and administration.

Real Estate Investment Trust (“REIT”) Conversion

In September 2012, we announced that our Board of Directors approved a plan for Equinix to pursue conversion to a REIT. On December 23, 2014, our Board of Directors formally approved our conversion to a REIT effective on January 1, 2015. We completed the implementation of the REIT conversion in 2014 and as a result, we will make a tax election for REIT status for the taxable year commencing January 1, 2015. The REIT conversion will include the data center operations in the U.S., Europe and Japan; data center operations in other jurisdictions will be designated as taxable REIT subsidiaries (“TRSs”).

As a REIT, we will generally be permitted to deduct from federal income taxes the dividends we pay to our stockholders (including, for this purpose, the value of any deemed distribution on account of adjustments to the conversion rate relating to our outstanding debt securities that are convertible into our common stock, provided the deemed distribution is not a preferential dividend. The income represented by such dividends will not be subject to federal taxation at the entity level but will be taxed, if at all, at the stockholder level. Nevertheless, the income of our TRSs which hold our U.S. operations that may not be REIT-compliant, are subject, as applicable, to federal and state corporate income tax. Likewise, our foreign subsidiaries continue to be subject to foreign income taxes in jurisdictions in which they hold assets or conduct operations, regardless of whether held or conducted through TRSs or through qualified REIT subsidiaries (“QRSs”). We are also subject to a separate corporate income tax on any gains recognized during a specified period (generally 10 years) following the REIT conversion that are attributable to “built-in” gains with respect to the assets that we owned on January 1, 2015. Our ability to qualify as a REIT will depend upon our continuing compliance with various requirements, including requirements related to the nature of our assets, the sources of our income and the distributions to our stockholders. If we fail to qualify as a REIT, we will be subject to federal income tax at regular corporate rates. Even if we qualify for taxation as a REIT, we may be subject to some federal, state, local and foreign taxes on our income and property in addition to taxes owed with respect to our TRS operations. In particular, while state income tax regimes often parallel the federal income tax regime for REITs, many states do not completely follow federal rules and some may not follow them at all.

In connection with our conversion to a REIT, we are seeking a private letter ruling (“PLR”) from the U.S. Internal Revenue Service (“IRS”). Our PLR request has multiple components, and we submitted the PLR request to the IRS in the fourth quarter of 2012.

We have incurred $81.4 million in costs to support our conversion to a REIT, including $49.7 million in 2014. We estimate that we will incur $2.0 million of one-time implementation costs to support the REIT conversion in 2015. In addition, we expect to incur a total of approximately $360.0 to $370.0 million in tax liabilities associated with a change in our methods of depreciating and amortizing various data center assets for tax purposes from our prior methods to methods that are more consistent with the characterization of such assets as real property for REIT purposes. The recapture expenses are generally payable over a four-year period starting in 2012 and, as of December 31, 2014, we have settled $281.0 million of the estimated federal and state tax liability related to the recapture of depreciation and amortization expenses. Prior to our decision to convert to a REIT, our balance sheet reflected our income tax liability as a non-current deferred tax liability. As a result of the REIT conversion, our non-current tax liability has been and will continue to be gradually and proportionally reclassified from non-current to current over the four-year period, which started in the third quarter of 2012. The current liability reflects the tax liability that relates to additional taxable income expected to be recognized within the twelve-month period from the date of the balance sheet. As a REIT, we also expect to incur approximately $10.0 million annually in compliance costs beginning in 2015.

On October 16, 2014, we announced the declaration by our Board of Directors of a special distribution (the “2014 Special Distribution”) of $416.0 million on our shares of common stock, payable in either common stock or cash to, and at the election of, our stockholders of record as of October 27, 2014 (the “Record Date”). Common stockholders elected to receive payment of the 2014 Special Distribution in the form of stock or cash, with the total cash payment to all stockholders limited to no more than 20% of the total distribution. In accordance with tax rules applicable to REIT conversions, in order for Equinix to be eligible to qualify for taxation as a REIT for federal income tax purposes effective for the taxable year commencing January 1, 2015, we are required to distribute, on or before December 31, 2015, our previously undistributed accumulated earnings and profits attributable to all taxable periods ending prior to January 1, 2015 (our “Pre-2015 Accumulated E&P”). The value of the 2014 Special Distribution, plus the value of the deemed distribution on account of the adjustment to the conversion rate relating to our outstanding 4.75% Convertible Subordinated Notes due June 15, 2016 (the “2016 Convertible Notes”) that was made as a result of the 2014 Special Distribution (the “2014 Conversion Rate Adjustment”), exceeded our Pre-2015 Accumulated E&P.

We intend to declare one or more special distributions in 2015 (the “2015 Special Distributions”), which would encompass some extraordinary items of taxable income that we expect to recognize in 2015, such as depreciation recapture in respect of accounting method changes commenced in our pre-REIT period and foreign earnings and profits recognized as dividend income. We estimate the aggregate amount of our 2015 Special Distributions, together with the expected value of the deemed distributions associated with any adjustments to the conversion rate of the 2016 Convertible Notes resulting from the 2015 Special Distributions (the “2015 Conversion Rate Adjustments”), will equal approximately $580.0 to $680.0 million. The conversion of our existing data center operations into the REIT and the addition of new entities into the REIT may also result in future special distributions.

We also expect to begin paying quarterly dividends in 2015 in connection with our conversion to a REIT effective January 1, 2015. On February 19, 2015, we announced a quarterly cash dividend of $1.69 per share payable on March 25, 2015, to shareholders of record on March 11, 2015.

In connection with the formal approval of our conversion to a REIT by our Board of Directors in late December 2014, we reassessed the deferred tax assets and liabilities of our U.S. operations included in the REIT structure during the fourth quarter of 2014. The reevaluation resulted in de-recognizing the deferred tax assets and liabilities of our REIT’s U.S. operations, excluding the deferred tax liabilities associated with the depreciation and amortization recapture expected in 2015. The de-recognition of the deferred tax assets and liabilities of our REIT’s U.S. operations occurred because the expected recovery or settlement of the related

15

Table of Contents

assets and liabilities will not result in deductible or taxable amounts in any post-REIT conversion periods. As a result of the de-recognition assessment, we recorded a significant income tax provision expense in the fourth quarter of 2014 of $324.1 million. The deferred tax assets and liabilities associated with our foreign operations, regardless of whether such foreign operations are part of the REIT conversion, are not subject to the de-recognition assessment. In addition, we don’t expect any “built-in” gains to be recognized within the next 10 years with respect to the REIT conversion.

We will continue to monitor our REIT compliance to maintain our status as a REIT. As necessary, we may convert certain of our data center operations in Canada and Asia Pacific into the REIT in the following years.

These reports are available as soon as reasonably practical after we file them with the SEC. Information contained on our website is not part of this Annual Report on Form 10-K.

In addition to the other information contained in this report, the following risk factors should be considered carefully in evaluating our business and us:

Risks Related to Operating as a REIT

We may not qualify or remain qualified as a REIT.

We expect to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”), commencing with our taxable year beginning January 1, 2015. We believe we are operating so as to qualify as a REIT under the Code and believe that our organization and method of operation complies with the rules and regulations promulgated under the Code and will enable us to continue to qualify as a REIT. However, we cannot assure you that we will qualify as a REIT, or that we will remain qualified as a REIT. Qualification as a REIT requires us to satisfy numerous requirements (some on an annual and others on a quarterly basis) established under highly technical and complex sections of the Code which may change from time to time and for which there are only limited judicial and administrative interpretations, and involves the determination of various factual matters and circumstances not entirely within our control. For example, in order to qualify as a REIT, we must derive at least 95% of our gross income in any year from qualifying sources. In addition, we must satisfy specified Asset Tests on a quarterly basis.

If, in any taxable year, we fail to qualify for taxation as a REIT and are not entitled to relief under the Code:

16

Table of Contents

Any such corporate tax liability could be substantial and would reduce the amount of cash available for other purposes.

In addition, if we fail to qualify as a REIT, we still will have incurred substantial costs to support the REIT conversion and may still be subject to federal and state tax liability of approximately $360.0 to $370.0 million resulting from the recapture of depreciation and amortization expenses, of which $281.0 million has been settled as of December 31, 2014.

As a REIT, failure to make required distributions would subject us to federal corporate income tax.

We expect to begin paying quarterly distributions in the first quarter of 2015, the amount, timing and form of which will be determined, and will be subject to adjustment, by our Board of Directors. To qualify and be taxed as a REIT, we are generally required to distribute at least 90% of our REIT taxable income (determined without regard to the dividends paid deduction and excluding net capital gain) each year to our stockholders. Generally, we expect to distribute all or substantially all of our REIT taxable income. If our cash available for distribution falls short of our estimates, we may be unable to maintain distributions that approximate our REIT taxable income and may fail to qualify for taxation as a REIT. In addition, our cash flows from operations may be insufficient to fund required distributions as a result of differences in timing between the actual receipt of income and the payment of expenses and the recognition of income and expenses for federal income tax purposes, or the effect of nondeductible expenditures, such as capital expenditures, payments of compensation for which Section 162(m) of the Code denies a deduction, the creation of reserves or required debt service or amortization payments.

To the extent that we satisfy the 90% distribution requirement but distribute less than 100% of our REIT taxable income, we will be subject to federal corporate income tax on our undistributed taxable income. In addition, we will be subject to a 4% nondeductible excise tax on our undistributed taxable income if the actual amount that we distribute to our stockholders for a calendar year is less than the minimum amount specified under the Code.

We may be required to borrow funds or raise equity to satisfy our REIT distribution requirements.

Depending on the ultimate size and timing of any 2015 Special Distributions and the cash outlays associated with our conversion to a REIT, or the size and timing of future regular or special distributions, including any distributions made to satisfy REIT distribution requirements and maintain our qualification and taxation as a REIT, we may need to borrow funds or raise equity, even if the then-prevailing market conditions are not favorable for these borrowings or offerings.

Any insufficiency of our cash flows to cover our REIT distribution requirements could adversely impact our ability to raise short- and long-term debt or to offer equity securities in order to fund distributions required to maintain our qualification and taxation as a REIT. Furthermore, the REIT distribution requirements may increase the financing we need to fund capital expenditures, future growth and expansion initiatives. This would increase our indebtedness. A significant increase in our outstanding debt could lead to a downgrade of our credit rating. A downgrade of our credit rating could negatively impact our ability to access credit markets. Further, certain of our current debt instruments limit the amount of indebtedness we and our subsidiaries may incur. Significantly more financing, therefore, may be unavailable, more expensive or restricted by the terms of our outstanding indebtedness. For a discussion of risks related to our substantial level of indebtedness, see “Other Risks”.

Whether we issue equity, at what price and the amount and other terms of any such issuances will depend on many factors, including alternative sources of capital, our then-existing leverage, our need for additional capital, market conditions and other factors beyond our control. If we raise additional funds through the issuance of equity securities or debt convertible into equity securities, the percentage of stock ownership by our existing stockholders may be reduced. In addition, new equity securities or convertible debt securities could have rights,

17

Table of Contents

preferences and privileges senior to those of our current stockholders, which could substantially decrease the value of our securities owned by them. Depending on the share price we are able to obtain, we may have to sell a significant number of shares in order to raise the capital we deem necessary to execute our long-term strategy, and our stockholders may experience dilution in the value of their shares as a result.

Legislative or other actions affecting REITs could have a negative effect on us or our stockholders.

At any time, the federal income tax laws governing REITs or the administrative interpretations of those laws may be amended. Federal and state tax laws are constantly under review by persons involved in the legislative process, the IRS, the U.S. Department of the Treasury and state taxing authorities. Changes to the tax laws, regulations and administrative interpretations, which may have retroactive application, could adversely affect us. In addition, some of these changes could have a more significant impact on us as compared to other REITs due to the nature of our business and our substantial use of TRSs. We cannot predict with certainty whether, when, in what forms, or with what effective dates, the tax laws, regulations and administrative interpretations applicable to us may be changed.

Complying with REIT requirements may limit our flexibility or cause us to forego otherwise attractive opportunities.

As a REIT for U.S. federal income tax purposes, we must continually satisfy tests concerning, among other things, the sources of our income, the nature and diversification of our assets and the amounts we distribute to our stockholders. For example, under the Code, no more than 25% of the value of the assets of a REIT may be represented by securities of our TRS and other nonqualifying assets. This limitation may affect our ability to make large investments in other non-REIT qualifying operations or assets. In addition, in order to maintain qualification as a REIT, we must annually distribute at least 90% of our REIT taxable income, determined without regard to the dividends paid deduction and excluding any net capital gains. Even if we maintain our qualification as a REIT, we will be subject to U.S. federal income tax at regular corporate rates for our undistributed REIT taxable income, as well as U.S. federal income tax at regular corporate rates for income recognized by our TRS. Because of these distribution requirements, we will likely not be able to fund future capital needs and investments from operating cash flow. As such, compliance with REIT tests may hinder our ability to make certain attractive investments, including the purchase of significant nonqualifying assets and the material expansion of non-real estate activities.

There are uncertainties relating to our estimate of our 2015 Special Distributions and the expected value of the deemed distributions associated with the 2015 Conversion Rate Adjustments, as well as the percentage of common stock and cash we may distribute in the 2015 Special Distributions.

We have provided an estimated range of the 2015 Special Distributions and the expected value of the deemed distributions associated with the 2015 Conversion Rate Adjustments. The 2015 Special Distributions will encompass our depreciation recapture in respect of our accounting method changes commenced in our pre-REIT period as well as dividend income recognized from the cumulative foreign earnings and profits of the data center operations outside the U.S. to be included in the REIT conversion as of January 1, 2015. However, our estimate of extraordinary items of taxable income in 2015 may be incorrect. For these reasons and others, our actual 2015 Special Distributions and, consequently, the estimated range of the sum of the Special Distributions together with the expected value of the deemed distributions associated with the 2015 Conversion Rate Adjustments, may be materially different from our current estimates.

We anticipate paying up to 20% of the 2015 Special Distributions in the form of cash and at least 80% in the form of common stock. We may in fact decide, based on our cash flows and strategic plans, IRS revenue procedures relating to distributions of earnings and profits, leverage and other factors, to pay these amounts in a different mix of cash and common stock.

18

Table of Contents

As a REIT, we are limited in our ability to fund distribution payments using cash generated through our TRSs.

Our ability to receive distributions from our TRSs is limited by the rules with which we must comply to maintain our status as a REIT. In particular, at least 75% of our gross income for each taxable year as a REIT must be derived from real estate. Consequently, no more than 25% of our gross income may consist of dividend income from our TRSs and other nonqualifying types of income. Thus, our ability to receive distributions from our TRSs may be limited, and may impact our ability to fund distributions to our stockholders using cash flows from our TRSs. Specifically, if our TRSs become highly profitable, we might become limited in our ability to receive net income from our TRSs in an amount required to fund distributions to our stockholders commensurate with that profitability.

In addition, a significant amount of our income and cash flows from our TRSs will be generated from our international operations. In many cases, there are local withholding taxes and currency controls that may impact our ability or willingness to repatriate funds to the United States to help satisfy REIT distribution requirements.

Our planned extensive use of TRSs, including for certain of our international operations, may cause us to fail to qualify as a REIT.

The net income of our TRSs is not required to be distributed to the REIT, and income that is not distributed to the REIT generally will not be subject to the REIT income distribution requirement. However, there may be limitations on our ability to accumulate earnings in our TRSs and the accumulation or reinvestment of significant earnings in our TRSs could result in adverse tax treatment. In particular, if the accumulation of cash in our TRSs causes the fair market value of our securities in our TRSs and other nonqualifying assets to exceed 25% of the fair market value of our assets, we would fail to qualify as a REIT.

Our cash distributions are not guaranteed and may fluctuate.

A REIT generally is required to distribute at least 90% of its REIT taxable income to its stockholders.

Our Board of Directors, in its sole discretion, will determine on a quarterly basis the amount of cash to be distributed to our stockholders based on a number of factors including, but not limited to, our results of operations, cash flow and capital requirements, economic conditions, tax considerations, borrowing capacity and other factors, including debt covenant restrictions that may impose limitations on cash payments, future acquisitions and divestitures and any stock repurchase program. Consequently, our distribution levels may fluctuate.

Even if we qualify as a REIT, some of our business activities are subject to corporate level income tax and foreign taxes, which will continue to reduce our cash flows, and we will have potential deferred and contingent tax liabilities.

As a REIT, we may be subject to some federal, state, local and foreign taxes on our income and assets, including alternative minimum taxes, taxes on any undistributed income, and state, local or foreign income, franchise, property and transfer taxes. In addition, we could in certain circumstances be required to pay an excise or penalty tax, which could be significant in amount, in order to utilize one or more relief provisions under the Code to maintain qualification for taxation as a REIT.

A portion of our business is conducted through wholly owned TRSs because certain of our business activities could generate nonqualifying REIT income as currently structured and operated. The income of our U.S. TRSs will continue to be subject to federal and state corporate income taxes. In addition, our international assets and operations will continue to be subject to taxation in the foreign jurisdictions where those assets are held or those operations are conducted. Any of these taxes would decrease our earnings and our available cash.

19

Table of Contents

We will also be subject to a federal corporate level tax at the highest regular corporate rate (currently 35%) on gain recognized from a sale of assets occurring within a specified period (generally ten years) after the effective date of our REIT election, that is, January 1, 2015, to the extent of the built-in-gain based on the fair market value of those assets on the effective date of the REIT election in excess of our then tax basis. In addition, depreciation recapture income that we will recognize in our 2015 and subsequent taxable years, as a result of accounting method changes that were effective prior to January 1, 2015, will be fully subject to this 35% tax.

In addition, the IRS and any state or local tax authority may successfully assert liabilities against us for corporate income taxes for our pre-REIT period, in which case we will owe these taxes plus applicable interest and penalties, if any. Moreover, any increase in taxable income for these pre-REIT periods will likely result in an increase in pre-REIT accumulated earnings and profits, which could either increase the taxable portion of our 2015 distributions to our stockholders or cause us to pay an additional taxable distribution to our stockholders after the relevant determination.

Restrictive loan covenants could prevent us from satisfying REIT distribution requirements.

Restrictions in our credit facility and our indentures may prevent us from satisfying our REIT distribution requirements, and we could fail to qualify for taxation as a REIT. If these limits do not jeopardize our qualification for taxation as a REIT but nevertheless prevent us from distributing 100% of our REIT taxable income, we would be subject to federal corporate income tax, and potentially a nondeductible excise tax, on the retained amounts. See “Other Risks” for further information on our restrictive loan covenants.

Complying with REIT requirements may limit our ability to hedge effectively and increase the cost of our hedging and may cause us to incur tax liabilities.

The REIT provisions of the Code limit our ability to hedge assets, liabilities, revenues and expenses. Generally, income from hedging transactions that we enter into to manage risk of interest rate changes with respect to borrowings made or to be made to acquire or carry real estate assets and income from certain currency hedging transactions related to our non-U.S. operations do not constitute “gross income” for purposes of the REIT gross income tests. To the extent that we enter into other types of hedging transactions, the income from those transactions is likely to be treated as nonqualifying income for purposes of the REIT gross income tests. As a result of these rules, we may need to limit our use of advantageous hedging techniques or implement those hedges through a TRS. This could increase the cost of our hedging activities because our TRSs would be subject to tax on income or gains resulting from hedges entered into by them or expose us to greater risks associated with changes in interest rates or exchange rates than we would otherwise want to bear. In addition, hedging losses in any of our TRSs generally will not provide any tax benefit, except for being carried forward for possible use against future capital gain in the TRSs.

We have limited experience operating as a REIT, which may adversely affect our financial condition, results of operations, cash flow, per share trading price of our common stock and ability to forecast dividends.

We began operating as a REIT on January 1, 2015 and, as such, have limited operating history as a REIT. In addition, prior to January 1, 2015 our senior management team had no prior experience operating a REIT. We can provide no assurance that our past experience has sufficiently prepared us to operate successfully as a REIT. Our inability to operate successfully as a REIT, including the failure to maintain REIT status, could adversely affect our business, financial condition and results of operations.

Distributions payable by REITs generally do not qualify for preferential tax rates.

Qualifying distributions payable by corporations to individuals, trusts and estates that are U.S. stockholders are currently eligible for federal income tax at preferential rates. Distributions payable by REITs, in contrast, generally are not eligible for the preferential rates. The preferential rates applicable to regular corporate

20

Table of Contents

distributions could cause investors who are individuals, trusts and estates to perceive investments in REITs to be relatively less attractive than investments in the stock of non-REIT corporations that pay distributions, which could adversely affect the value of the stock of REITs, including our common stock.

Our certificate of incorporation contains restrictions on the ownership and transfer of our stock, though they may not be successful in preserving our REIT status.

As a REIT, no more than 50% of the value of outstanding shares of our stock may be owned, beneficially or constructively, by five or fewer individuals at any time during the last half of each taxable year other than the first year for which we elect to be taxed as a REIT. In addition, rents from “affiliated tenants” will not qualify as qualifying REIT income if we own 10% or more by vote or value of the customer, whether directly or after application of attribution rules under the Code. Subject to certain exceptions, our certificate of incorporation prohibits any stockholder from owning beneficially or constructively more than (i) 9.8% in value of the outstanding shares of all classes or series of our capital stock or (ii) 9.8% in value or number, whichever is more restrictive, of the outstanding shares of any class or series of our capital stock. We refer to these restrictions collectively as the “ownership limits” and we included them in our certificate of incorporation to facilitate our compliance with REIT tax rules. The constructive ownership rules under the Code are complex and may cause the outstanding stock owned by a group of related individuals or entities to be deemed to be constructively owned by one individual or entity. As a result, the acquisition of less than 9.8% of our outstanding common stock (or the outstanding shares of any class or series of our stock) by an individual or entity could cause that individual or entity or another individual or entity to own constructively in excess of the relevant ownership limits. Any attempt to own or transfer shares of our common stock or of any of our other capital stock in violation of these restrictions may result in the shares being automatically transferred to a charitable trust or may be void. Even though our certificate of incorporation contains the ownership limits, there can be no assurance that these provisions will be effective to prevent our REIT status from being jeopardized, including under the affiliated tenant rule. Furthermore, there can be no assurance that we will be able to enforce the ownership limits. If the restrictions in our certificate of incorporation are not effective and as a result we fail to satisfy the REIT tax rules described above, then absent an applicable relief provision, we will fail to qualify as a REIT.

Other Risks

Acquisitions present many risks, and we may not realize the financial or strategic goals that were contemplated at the time of any transaction.

Over the last several years, we have completed several acquisitions, including that of Switch & Data Facilities Company, Inc. (“Switch and Data”) in 2010, an approximate 53% controlling equity interest in ALOG Data Centers do Brasil S.A. (“ALOG”) in 2011 and the remaining outstanding shares of ALOG in 2014, Asia Tone Limited and ancotel GmbH in 2012, an acquisition of a Dubai IBX data center in 2012, an acquisition of a carrier hotel in Frankfurt in 2013 and the acquisition of professional services firm Nimbo in 2015. We may make additional acquisitions in the future, which may include (i) acquisitions of businesses, products, services or technologies that we believe to be complementary, (ii) acquisitions of new IBX data centers or real estate for development of new IBX data centers or (iii) acquisitions through investments in local data center operators. We may pay for future acquisitions by using our existing cash resources (which may limit other potential uses of our cash), incurring additional debt (which may increase our interest expense, leverage and debt service requirements) and/or issuing shares (which may dilute our existing stockholders and have a negative effect on our earnings per share). Acquisitions expose us to potential risks, including:

21

Table of Contents

The occurrence of any of these risks could have a material adverse effect on our business, results of operations, financial condition or cash flows.

We cannot assure that the price of any future acquisitions of IBX data centers will be similar to prior IBX data center acquisitions. In fact, we expect costs required to build or render new IBX data centers operational to increase in the future. If our revenue does not keep pace with these potential acquisition and expansion costs, we may not be able to maintain our current or expected margins as we absorb these additional expenses. There is no assurance we would successfully overcome these risks or any other problems encountered with these acquisitions.

Our substantial debt could adversely affect our cash flows and limit our flexibility to raise additional capital.

We have a significant amount of debt and may need to incur additional debt to support our growth. Additional debt may also be incurred to fund future acquisitions, any future special distributions, regular distributions or the other cash outlays associated with qualifying as or maintaining qualification as a REIT. As of

22

Table of Contents

December 31, 2014, our total indebtedness was approximately $4.7 billion, our stockholders’ equity was $2.3 billion and our cash and investments totaled $1.1 billion. In addition, as of December 31, 2014, we had approximately $956.7 million of additional liquidity available to us from our $1.0 billion revolving credit facility as part of a $1.5 billion senior credit facility agreement entered into with a group of lenders. Some of our debt contains covenants which may limit our operating flexibility. In addition to our substantial debt, we lease a majority of our IBX data centers and certain equipment under non-cancellable lease agreements, the majority of which are accounted for as operating leases. As of December 31, 2014, our total minimum operating lease commitments under those lease agreements, excluding potential lease renewals, was approximately $993.3 million, which represents off-balance sheet commitments.

Our substantial amount of debt and related covenants, and our off-balance sheet commitments, could have important consequences. For example, they could:

The occurrence of any of the foregoing factors could have a material adverse effect on our business, results of operations and financial condition. In addition, the performance of our stock price may trigger events that would require the write-off of a significant portion of our debt issuance costs related to our convertible debt, which may have a material adverse effect on our results of operations.

We may also need to refinance a portion of our outstanding debt as it matures. There is a risk that we may not be able to refinance existing debt or that the terms of any refinancing may not be as favorable as the terms of our existing debt. Furthermore, if prevailing interest rates or other factors at the time of refinancing result in higher interest rates upon refinancing, then the interest expense relating to that refinanced indebtedness would increase. These risks could materially adversely affect our financial condition, cash flows and results of operations.

Global economic uncertainty and debt issues could adversely impact our business and financial condition.

The varying pace of global economic recovery continues to create uncertainty and unpredictability and add risk to our future outlook. An uncertain global economy could also result in churn in our customer base, reductions in revenues from our offerings, longer sales cycles, slower adoption of new technologies and increased price competition, adversely affecting our liquidity. The uncertain economic environment could also have an impact on our foreign exchange forward contracts if our counterparties’ credit deteriorates or they are otherwise unable to perform their obligations. Finally, our ability to access the capital markets may be severely restricted at a time when we would like, or need, to do so which could have an impact on our flexibility to pursue additional expansion opportunities and maintain our desired level of revenue growth in the future.

The market price of our stock may continue to be highly volatile, and the value of an investment in our common stock may decline.

Since January 1, 2014, the closing sale price of our common stock on the NASDAQ Global Select Market has ranged from $170.48 to $235.38 per share. The market price of the shares of our common stock has been and may continue to be highly volatile. General economic and market conditions, and market conditions for telecommunications stocks in general, may affect the market price of our common stock.

Announcements by us or others, or speculations about our future plans, may also have a significant impact on the market price of our common stock. These may relate to:

The stock market has from time to time experienced extreme price and volume fluctuations, which have particularly affected the market prices for telecommunications companies, and which have often been unrelated to their operating performance. These broad market fluctuations may adversely affect the market price of our common stock. Furthermore, companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Securities litigation against us could result in substantial costs and/or damages, and divert management’s attention from other business concerns, which could seriously harm our business.

If we are not able to generate sufficient operating cash flows or obtain external financing, our ability to fund incremental expansion plans may be limited.

Our capital expenditures, together with ongoing operating expenses, obligations to service our debt and the cash outlays associated with our REIT distribution requirements, will be a substantial drain on our cash flow and may decrease our cash balances. Additional debt or equity financing may not be available when needed or, if available, may not be available on satisfactory terms. Our inability to obtain additional debt and/or equity financing or to generate sufficient cash from operations may require us to prioritize projects or curtail capital expenditures which could adversely affect our results of operations.

Fluctuations in foreign currency exchange rates in the markets in which we operate internationally could harm our results of operations.

We may experience gains and losses resulting from fluctuations in foreign currency exchange rates. To date, the majority of our revenues and costs are denominated in U.S. dollars; however, the majority of revenues and costs in our international operations are denominated in foreign currencies. Where our prices are denominated in

24

Table of Contents

U.S. dollars, our sales and revenues could be adversely affected by declines in foreign currencies relative to the U.S. dollar, thereby making our offerings more expensive in local currencies. We are also exposed to risks resulting from fluctuations in foreign currency exchange rates in connection with our international expansions. To the extent we are paying contractors in foreign currencies, our expansions could cost more than anticipated as a result of declines in the U.S dollar relative to foreign currencies. In addition, fluctuating foreign currency exchange rates have a direct impact on how our international results of operations translate into U.S. dollars.

Although we currently undertake, and may decide in the future to further undertake, foreign exchange hedging transactions to reduce foreign currency transaction exposure, we do not currently intend to eliminate all foreign currency transaction exposure. In addition, REIT compliance rules may restrict our ability to enter into hedging transactions. Therefore, any weakness of the U.S. dollar may have a positive impact on our consolidated results of operations because the currencies in the foreign countries in which we operate may translate into more U.S. dollars. However, if the U.S. dollar strengthens relative to the currencies of the foreign countries in which we operate, our consolidated financial position and results of operations may be negatively impacted as amounts in foreign currencies will generally translate into fewer U.S. dollars. For additional information on foreign currency risk, refer to our discussion of foreign currency risk in “Quantitative and Qualitative Disclosures About Market Risk” included in Item 7A of this Annual Report on Form 10-K.

Changes in U.S. or foreign tax laws, regulations, or interpretations thereof, including changes to tax rates, may adversely affect our financial statements and cash taxes.

We are a U.S. company with global subsidiaries and are subject to income taxes in the U.S. and many foreign jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes. Although we believe that we have adequately assessed and accounted for our potential tax liabilities, and that our tax estimates are reasonable, there can be no certainty that additional taxes will not be due upon audit of our tax returns or as a result of changes to the tax laws and interpretations thereof. The U.S. Congress as well as the governments of many of the countries in which we operate are actively discussing changes to the corporate recognition and taxation of worldwide income. The nature and timing of any changes to each jurisdiction’s tax laws and the impact on our future tax liabilities cannot be predicted with any accuracy but could materially and adversely impact our results of operations and financial position or cash flows.

We are continuing to invest in our expansion efforts but may not have sufficient customer demand in the future to realize expected returns on these investments.

We are considering the acquisition or lease of additional properties and the construction of new IBX data centers beyond those expansion projects already announced. We will be required to commit substantial operational and financial resources to these IBX data centers, generally 12 to 18 months in advance of securing customer contracts, and we may not have sufficient customer demand in those markets to support these centers once they are built. In addition, unanticipated technological changes could affect customer requirements for data centers, and we may not have built such requirements into our new IBX data centers. Either of these contingencies, if they were to occur, could make it difficult for us to realize expected or reasonable returns on these investments.

Our offerings have a long sales cycle that may harm our revenues and operating results.

A customer’s decision to purchase our offerings typically involves a significant commitment of resources. In addition, some customers will be reluctant to commit to locating in our IBX data centers until they are confident that the IBX data center has adequate carrier connections. As a result, we have a long sales cycle. Furthermore, we may devote significant time and resources in pursuing a particular sale or customer that does not result in revenue. We have also significantly expanded our sales force in recent years, and it will take time for these new hires to become fully productive.

25

Table of Contents

Delays due to the length of our sales cycle may materially and adversely affect our revenues and operating results, which could harm our ability to meet our forecasts and cause volatility in our stock price.

Any failure of our physical infrastructure or offerings could lead to significant costs and disruptions that could reduce our revenue and harm our business reputation and financial results.

Our business depends on providing customers with highly reliable solutions. We must safehouse our customers’ infrastructure and equipment located in our IBX data centers. We own certain of our IBX data centers, but others are leased by us, and we rely on the landlord for basic maintenance of our leased IBX data centers. If such landlord has not maintained a leased property sufficiently, we may be forced into an early exit from the center which could be disruptive to our business. Furthermore, we continue to acquire IBX data centers not built by us. If we discover that these IBX data centers and their infrastructure assets are not in the condition we expected when they were acquired, we may be required to incur substantial additional costs to repair or upgrade the centers.

The offerings we provide in each of our IBX data centers are subject to failure resulting from numerous factors, including:

Problems at one or more of our IBX data centers, whether or not within our control, could result in service interruptions or significant equipment damage. We have service level commitment obligations to certain of our customers. As a result, service interruptions or significant equipment damage in our IBX data centers could result in difficulty maintaining service level commitments to these customers and potential claims related to such failures. Because our IBX data centers are critical to many of our customers’ businesses, service interruptions or significant equipment damage in our IBX data centers could also result in lost profits or other indirect or consequential damages to our customers. We cannot guarantee that a court would enforce any contractual limitations on our liability in the event that one of our customers brings a lawsuit against us as a result of a problem at one of our IBX data centers. In addition, any loss of service, equipment damage or inability to meet our service level commitment obligations could reduce the confidence of our customers and could consequently impair our ability to obtain and retain customers, which would adversely affect both our ability to generate revenues and our operating results.

Furthermore, we are dependent upon Internet service providers, telecommunications carriers and other website operators in the Americas, Asia-Pacific and EMEA regions and elsewhere, some of which have experienced significant system failures and electrical outages in the past. Our customers may in the future experience difficulties due to system failures unrelated to our systems and offerings. If, for any reason, these providers fail to provide the required services, our business, financial condition and results of operations could be materially and adversely impacted.

We are currently making significant investments in our back office information technology systems, including those surrounding the customer experience from initial quote to customer billing, and upgrading our worldwide financial application suite. Difficulties, distractions or disruptions to these efforts may interrupt our normal operations and adversely affect our business and operating results.

Commencing in 2012, we began a significant project to overhaul our back office systems that support the customer experience from initial quote to customer billing and our revenue recognition process. Additionally, commencing in 2013, we began to devote significant resources to the upgrade of our worldwide financial application suite from Oracle’s version 11i to R12. Both projects have continued into 2015. Oracle has already begun to discontinue its support for our current business application suite. While the Oracle financial application suite implementation was largely completed in July 2014 and the initial implementation of the systems to support our billing and revenue process was completed in August 2014, substantial work continues on our back office systems. As a result of that discontinued support and our continued work on these projects, we may experience difficulties with our systems, management distraction and significant business disruptions. Difficulties with our systems may interrupt our ability to accept and deliver customer orders and may adversely impact our overall financial operations, including our accounts payable, accounts receivables, general ledger, close processes, internal financial controls and our ability to otherwise run and track our business. We may need to expend significant attention, time and resources to correct problems or find alternative sources for performing these functions. All of these changes to our financial systems create an increased risk of deficiencies in our internal controls over financial reporting until such systems are stabilized. Such significant investments in our back office systems may take longer to complete and cost more than originally planned. In addition, we may not realize the full benefits we hoped to achieve and there is a risk of an impairment charge if we decide that portions of these projects will not ultimately benefit the company or are de-scoped. Any such difficulty or disruption may adversely affect our business and operating results.

The insurance coverage that we purchase may prove to be inadequate.

We carry liability, property, business interruption and other insurance policies to cover insurable risks to our company. We select the types of insurance, the limits and the deductibles based on our specific risk profile, the cost of the insurance coverage versus its perceived benefit and general industry standards. Our insurance policies contain industry standard exclusions for events such as war and nuclear reaction. We purchase minimal levels of earthquake insurance for certain of our IBX data centers, but for most of our data centers, including many in California, we have elected to self-insure. The earthquake and flood insurance that we do purchase would be subject to high deductibles and any of the limits of insurance that we purchase could prove to be inadequate, which could materially and adversely impact our business, financial condition and results of operations.

Our construction of additional new IBX data centers or IBX data center expansions could involve significant risks to our business.

In order to sustain our growth in certain of our existing and new markets, we must expand an existing data center, lease a new facility or acquire suitable land, with or without structures, to build new IBX data centers from the ground up. Expansions or new builds are currently underway, or being contemplated, in many of our markets. Any related construction requires us to carefully select and rely on the experience of one or more designers, general contractors, and associated subcontractors during the design and construction process. Should a designer, general contractor, or significant subcontractor experience financial or other problems during the design or construction process, we could experience significant delays, increased costs to complete the project and/or other negative impacts to our expected returns.

Site selection is also a critical factor in our expansion plans. There may not be suitable properties available in our markets with the necessary combination of high power capacity and fiber connectivity, or selection may be limited. Thus, while we may prefer to locate new IBX data centers adjacent to our existing locations it may not always be possible. In the event we decide to build new IBX data centers separate from our existing IBX data

27

Table of Contents

centers, we may provide interconnection solutions to connect these two centers. Should these solutions not provide the necessary reliability to sustain connection, this could result in lower interconnection revenue and lower margins and could have a negative impact on customer retention over time.

Environmental regulations may impose upon us new or unexpected costs.

We are subject to various federal, state, local and international environmental and health and safety laws and regulations, including those relating to the generation, storage, handling and disposal of hazardous substances and wastes. Certain of these laws and regulations also impose joint and several liability, without regard to fault, for investigation and cleanup costs on current and former owners and operators of real property and persons who have disposed of or released hazardous substances into the environment. Our operations involve the use of hazardous substances and materials such as petroleum fuel for emergency generators, as well as batteries, cleaning solutions and other materials. In addition, we lease, own or operate real property at which hazardous substances and regulated materials have been used in the past. At some of our locations, hazardous substances or regulated materials are known to be present in soil or groundwater, and there may be additional unknown hazardous substances or regulated materials present at sites we own, operate or lease. At some of our locations, there are land use restrictions in place relating to earlier environmental cleanups that do not materially limit our use of the sites. To the extent any hazardous substances or any other substance or material must be cleaned up or removed from our property, we may be responsible under applicable laws, regulations or leases for the removal or cleanup of such substances or materials, the cost of which could be substantial.

In addition, we are subject to environmental, health and safety laws regulating air emissions, storm water management and other issues arising in our business. While these obligations do not normally impose material costs upon our operations, unexpected events, equipment malfunctions and human error, among other factors, can lead to violations of environmental laws, regulations or permits. Furthermore, environmental laws and regulations change frequently and may require additional investment to maintain compliance. Noncompliance with existing, or adoption of more stringent, environmental or health and safety laws and regulations or the discovery of previously unknown contamination could require us to incur costs or become the basis of new or increased liabilities that could be material.

Regulation of greenhouse gas (“GHG”) emissions could increase the cost of electricity by reducing supplies of electricity generated from fossil fuels, by requiring the use of more expensive generating methods or by imposing taxes or fees upon electricity generation or use. Electricity is a material cost in connection with our business, and an increase in the cost of electricity, whether from regulations of GHGs or otherwise, could adversely affect us.

Regulations to limit GHG emissions have been in force in the European Union for some time. In the U.S., regulation of GHGs is in force for new sources under existing law and regulations. In addition, the U.S. Environmental Protection Agency (“EPA”) has proposed regulations under existing statutory authority that would require states to reduce GHG emissions by 30% by 2030. Certain states, like California, regulate GHG emissions by imposing regulatory caps on allowances and by selling or auctioning the rights to such emissions. These programs have not had a material adverse effect on our electricity costs to date, but due to the market-driven nature of some of the programs, could do so in the future.

In addition, regulation of GHGs is subject to change globally and nationally. For example, the United States and China recently announced an agreement regarding climate change that would require China to consider regulating its GHG emissions to prevent further increases in emissions of GHGs by 2030. In order for China to meet this commitment, China may impose limitations on fossil fuel generation or costs upon electricity, similar to those imposed in the U.S. and elsewhere. In other international forums, new commitments under the International Convention on Climate Change could result in new limits on GHG emissions within participating nations. Any such new regulations could trigger increases in electricity costs that could adversely affect our business in affected countries.

28

Table of Contents

Even existing programs can change over time in ways that affect our operations. California’s cap-and-trade program was expanded on January 1, 2015 to require fuel distributors (for example, gas pipeline companies and diesel fuel distributors) to obtain allowances for the GHG emissions attributable to the combustion of the fuels they sell. Such regulations have increased our costs for both electricity and fuel (for example, for emergency generators) in California.

The physical impacts of climate change, including extreme weather conditions such as heat waves, could materially increase our costs of operation due to, for example, an increase in our energy use in order to maintain the temperature and internal environment of our data centers necessary for our operations. To the extent any environmental laws enacted or regulations impose new or unexpected costs, our business, results of operations or financial condition may be adversely affected.

If we are unable to recruit or retain qualified personnel, our business could be harmed.

We must continue to identify, hire, train and retain IT professionals, technical engineers, operations employees, and sales, marketing, finance and senior management personnel who maintain relationships with our customers and who can provide the technical, strategic and marketing skills required for our company to grow. There is a shortage of qualified personnel in these fields, and we compete with other companies for the limited pool of talent. The failure to recruit and retain necessary personnel, including, but not limited to, members of our executive team, could harm our business and our ability to grow our company.

We may not be able to compete successfully against current and future competitors.

We must be able to differentiate our IBX data centers and product offerings from those of our competitors. In addition to competing with other neutral colocation providers, we compete with traditional colocation providers, including telecommunications companies, carriers, internet service providers, managed services providers and large REITs who also operate in our market and may enjoy a cost advantage in providing offerings similar to those provided by our IBX data centers. We may experience competition from our landlords which could also reduce the amount of space available to us for expansion in the future. Rather than leasing available space in our buildings to large single tenants, they may decide to convert the space instead to smaller square foot units designed for multi-tenant colocation use, blurring the line between retail and wholesale space. We may also face competition from existing competitors or new entrants to the market seeking to replicate our global IBX data center concept by building or acquiring data centers, offering colocation on neutral terms or by replicating our strategy and messaging. Finally, customers may also decide it is cost-effective for them to build out their own data centers. Once customers have an established data center footprint, either through a relationship with one of our competitors or through in-sourcing, it may be extremely difficult to convince them to relocate to our IBX data centers.

Some of our competitors may adopt aggressive pricing policies, especially if they are not highly leveraged or have lower return thresholds than we do. As a result, we may suffer from pricing pressure that would adversely affect our ability to generate revenues. Some of these competitors may also provide our target customers with additional benefits, including bundled communication services or cloud services, and may do so in a manner that is more attractive to our potential customers than obtaining space in our IBX data centers. Similarly, with growing acceptance of cloud-based technologies, Equinix is at risk losing customers that may decide to fully leverage cloud infrastructure offerings instead of managing their own. Competitors could also operate more successfully or form alliances to acquire significant market share.

Failure to compete successfully may materially adversely affect our financial condition, cash flows and results of operations.

Our business could be harmed by prolonged power outages or shortages, increased costs of energy or general lack of availability of electrical resources.

Our IBX data centers are susceptible to regional costs of power, power shortages, planned or unplanned power outages and limitations, especially internationally, on the availability of adequate power resources.

Power outages, such as those relating to the earthquake and tsunami in Japan in 2011 or Superstorm Sandy, which hit the U.S. East Coast in 2012, could harm our customers and our business. We attempt to limit our exposure to system downtime by using backup generators and power supplies; however, we may not be able to limit our exposure entirely even with these protections in place. Some of our IBXs are located in leased buildings where, depending upon the lease requirements and number of tenants involved, we may or may not control some or all of the infrastructure including generators and fuel tanks. As a result, in the event of a power outage, we may be dependent upon the landlord, as well as the utility company, to restore the power.

In addition, global fluctuations in the price of power can increase the cost of energy, and although contractual price increase clauses exist in the majority of our customer agreements, we may not always choose to pass these increased costs on to our customers.

In each of our markets, we rely on third parties to provide a sufficient amount of power for current and future customers. At the same time, power and cooling requirements are growing on a per unit basis. As a result, some customers are consuming an increasing amount of power per cabinet. We generally do not control the amount of power our customers draw from their installed circuits. This means that we could face power limitations in our IBX data centers. This could have a negative impact on the effective available capacity of a given center and limit our ability to grow our business, which could have a negative impact on our financial performance, operating results and cash flows.

We may also have difficulty obtaining sufficient power capacity for potential expansion sites in new or existing markets. We may experience significant delays and substantial increased costs demanded by the utilities to provide the level of electrical service required by our current IBX data center designs.

If our internal controls are found to be ineffective, our financial results or our stock price may be adversely affected.

Our most recent evaluation of our controls resulted in our conclusion that, as of December 31, 2014, in compliance with Section 404 of the Sarbanes-Oxley Act of 2002, our internal controls over financial reporting were effective. Our ability to manage our operations and growth, through, for example, ongoing billing system updates being deployed into production during 2015, will require us to further develop our controls and reporting systems and implement or amend new or existing controls and reporting systems. All of these changes to our financial systems create an increased risk of deficiencies in our internal controls over financial reporting until such systems are stabilized. If, in the future, our internal control over financial reporting is found to be ineffective, or if a material weakness is identified in our controls over financial reporting, our financial results may be adversely affected. Investors may also lose confidence in the reliability of our financial statements which could adversely affect our stock price.

If we cannot effectively manage our international operations, and successfully implement our international expansion plans, our revenues may not increase and our business and results of operations would be harmed.

For the years ended December 31, 2014, 2013 and 2012, we recognized approximately 49%, 46% and 44%, respectively, of our revenues outside the U.S. We currently operate outside of the U.S. in Canada, Brazil, EMEA and Asia-Pacific.

To date, the network neutrality of our IBX data centers and the variety of networks available to our customers has often been a competitive advantage for us. In certain of our acquired IBX data centers in the Asia-Pacific region the limited number of carriers available reduces that advantage. As a result, we may need to adapt our key revenue-generating offerings and pricing to be competitive in those markets. In addition, we are currently undergoing expansions or evaluating expansion opportunities outside of the U.S. Undertaking and managing expansions in foreign jurisdictions may present unanticipated challenges to us.

Our international operations are generally subject to a number of additional risks, including:

In addition, compliance with international and U.S. laws and regulations that apply to our international operations increases our cost of doing business in foreign jurisdictions. These laws and regulations include data privacy requirements, labor relations laws, tax laws, anti-competition regulations, import and trade restrictions, export requirements, economic and trade sanctions, U.S. laws such as the Foreign Corrupt Practices Act and local laws which also prohibit corrupt payments to governmental officials. Violations of these laws and regulations could result in fines, criminal sanctions against us, our officers or our employees, and prohibitions on the conduct of our business. Any such violations could include prohibitions on our ability to offer our offerings in one or more countries, could delay or prevent potential acquisitions, and could also materially damage our reputation, our brand, our international expansion efforts, our ability to attract and retain employees, our business and our operating results. Our success depends, in part, on our ability to anticipate and address these risks and manage these difficulties.

Economic uncertainty in developing markets could adversely affect our revenue and earnings.

We conduct business, or are contemplating expansion, in developing markets with economies that tend to be more volatile than those in the U.S. and Western Europe. The risk of doing business in developing markets such as Brazil, China, India, Indonesia, Russia, the United Arab Emirates and other economically volatile areas could adversely affect our operations and earnings. Such risks include the financial instability among customers in these regions, political instability, fraud or corruption and other non-economic factors such as irregular trade

31

Table of Contents

flows that need to be managed successfully with the help of the local governments. In addition, commercial laws in some developing countries can be vague, inconsistently administered and retroactively applied. If we are deemed not to be in compliance with applicable laws in developing countries where we conduct business, our prospects and business in those countries could be harmed, which could then have a material adverse impact on our results of operations and financial position. Our failure to successfully manage economic, political and other risks relating to doing business in developing countries and economically and politically volatile areas could adversely affect our business.

The use of high power density equipment may limit our ability to fully utilize our older IBX data centers.

Some customers have increased their use of high power density equipment, such as blade servers, in our IBX data centers which has increased the demand for power on a per cabinet basis. Because many of our IBX data centers were built a number of years ago, the current demand for power may exceed the designed electrical capacity in these centers. As power, not space, is a limiting factor in many of our IBX data centers, our ability to fully utilize those IBX data centers may be limited. The ability to increase the power capacity of an IBX data center, should we decide to, is dependent on several factors including, but not limited to, the local utility’s ability to provide additional power; the length of time required to provide such power; and/or whether it is feasible to upgrade the electrical infrastructure of an IBX data center to deliver additional power to customers. Although we are currently designing and building to a higher power specification than that of many of our older IBX data centers, there is a risk that demand will continue to increase and our IBX data centers could become underutilized sooner than expected.

We expect our operating results to fluctuate.

We have experienced fluctuations in our results of operations on a quarterly and annual basis. The fluctuations in our operating results may cause the market price of our common stock to be volatile. We may experience significant fluctuations in our operating results in the foreseeable future due to a variety of factors, including, but not limited to:

32

Table of Contents

Any of the foregoing factors, or other factors discussed elsewhere in this report, could have a material adverse effect on our business, results of operations and financial condition. Although we have experienced growth in revenues in recent quarters, this growth rate is not necessarily indicative of future operating results. Prior to 2008, we had generated net losses every fiscal year since inception. It is possible that we may not be able to generate net income on a quarterly or annual basis in the future. In addition, a relatively large portion of our expenses are fixed in the short-term, particularly with respect to lease and personnel expenses, depreciation and amortization and interest expenses. Therefore, our results of operations are particularly sensitive to fluctuations in revenues. As such, comparisons to prior reporting periods should not be relied upon as indications of our future performance. In addition, our operating results in one or more future quarters may fail to meet the expectations of securities analysts or investors.

Our days sales outstanding (DSO) of our accounts receivables have been increasing.

Although we have historically experienced a record of strong collection of our accounts receivables as evidenced by our prior DSO metrics, our DSO has increased over the past few quarters. We have recently centralized responsibilities for customer billing and collections in the EMEA region. This transition of responsibilities has impacted our DSO efforts. We are also implementing a new billing system. The initial implementation of this system was completed in August 2014, but the full implementation of the system is not expected to be complete until later in 2015. The ongoing changes in the billing system may result in further delays in our billing and collections. While we believe these are temporary issues that will resolve themselves over time, the overall negative impact to our DSO has had an impact to our operating cash flows, liquidity and financial performance. If we are unable to resolve the underlying issues that are contributing to our current DSO levels, our operating cash flows, liquidity and financial performance may continue to be impacted.

We may incur goodwill and other intangible asset impairment charges, or impairment charges to our property, plant and equipment, which could result in a significant reduction to our earnings.

In accordance with GAAP, we are required to assess our goodwill and other intangible assets annually, or more frequently whenever events or changes in circumstances indicate potential impairment, such as changing market conditions or any changes in key assumptions. If the testing performed indicates that an asset may not be recoverable, we are required to record a non-cash impairment charge for the difference between the carrying value of the goodwill or other intangible assets and the implied fair value of the goodwill or other intangible assets in the period the determination is made.

We also monitor the remaining net book values of our property, plant and equipment periodically, including at the individual IBX data center level. Although each individual IBX data center is currently performing in line with our expectations, the possibility that one or more IBX data centers could begin to under-perform relative to our expectations is possible and may also result in non-cash impairment charges.

These charges could be significant, which could have a material adverse effect on our business, results of operations or financial condition.

We have incurred substantial losses in the past and may incur additional losses in the future.

As of December 31, 2014, our accumulated deficit was $296.0 million. Although we have generated net income for each fiscal year since 2008, except for the year ended December 31, 2014, we are also currently investing heavily in our future growth through the build out of multiple additional IBX data centers and IBX data center expansions as well as acquisitions of complementary businesses. As a result, we will incur higher depreciation and other operating expenses, as well as acquisition costs and interest expense, that may negatively impact our ability to sustain profitability in future periods unless and until these new IBX data centers generate enough revenue to exceed their operating costs and cover our additional overhead needed to scale our business for this anticipated growth. The current global financial uncertainty may also impact our ability to sustain profitability if we cannot generate sufficient revenue to offset the increased costs of our recently-opened IBX data centers or IBX data centers currently under construction. In addition, costs associated with the acquisition and integration of any acquired companies, as well as the additional interest expense associated with debt financing we have undertaken to fund our growth initiatives, may also negatively impact our ability to sustain profitability. Finally, given the competitive and evolving nature of the industry in which we operate, we may not be able to sustain or increase profitability on a quarterly or annual basis.

The failure to obtain favorable terms when we renew our IBX data center leases, or the failure to renew such leases, could harm our business and results of operations.

While we own certain of our IBX data centers, others are leased under long-term arrangements with lease terms expiring at various dates through 2053. These leased centers have all been subject to significant development by us in order to convert them from, in most cases, vacant buildings or warehouses into IBX data centers. Most of our IBX data center leases have renewal options available to us. However, many of these renewal options provide for the rent to be set at then-prevailing market rates. To the extent that then-prevailing market rates or negotiated rates are higher than present rates, these higher costs may adversely impact our business and results of operations, or we may decide against renewing the lease. In the event that an IBX data center lease does not have a renewal option, or we fail to exercise a renewal option in a timely fashion and lose our right to renew the lease, we may not be successful in negotiating a renewal of the lease with the landlord. A failure to renew a lease could force us to exit a building prematurely, which could be disruptive to our business, harm our customer relationships, expose us to liability under our customer contracts, cause us to take impairment charges and negatively affect our operating results.

We depend on a number of third parties to provide Internet connectivity to our IBX data centers; if connectivity is interrupted or terminated, our operating results and cash flow could be materially and adversely affected.

The presence of diverse telecommunications carriers’ fiber networks in our IBX data centers is critical to our ability to retain and attract new customers. We are not a telecommunications carrier, and as such, we rely on third parties to provide our customers with carrier services. We believe that the availability of carrier capacity will directly affect our ability to achieve our projected results. We rely primarily on revenue opportunities from the telecommunications carriers’ customers to encourage them to invest the capital and operating resources required to connect from their centers to our IBX data centers. Carriers will likely evaluate the revenue opportunity of an IBX data center based on the assumption that the environment will be highly competitive. We cannot provide assurance that each and every carrier will elect to offer its services within our IBX data centers or that once a carrier has decided to provide Internet connectivity to our IBX data centers that it will continue to do so for any period of time.

Our new IBX data centers require construction and operation of a sophisticated redundant fiber network. The construction required to connect multiple carrier facilities to our IBX data centers is complex and involves factors outside of our control, including regulatory processes and the availability of construction resources. Any hardware or fiber failures on this network may result in significant loss of connectivity to our new IBX data center expansions. This could affect our ability to attract new customers to these IBX data centers or retain existing customers.

If the establishment of highly diverse Internet connectivity to our IBX data centers does not occur, is materially delayed or is discontinued, or is subject to failure, our operating results and cash flow will be adversely affected.

We may be vulnerable to security breaches which could disrupt our operations and have a material adverse effect on our financial performance and operating results.

A party who is able to compromise the security measures on our networks or the security of our infrastructure could misappropriate either our proprietary information or the personal information of our customers, or cause interruptions or malfunctions in our operations or our customers’ operations. As we provide assurances to our customers that we provide the highest level of security, such a compromise could be particularly harmful to our brand and reputation. We may be required to expend significant capital and resources to protect against such threats or to alleviate problems caused by breaches in security. As techniques used to breach security change frequently, and are generally not recognized until launched against a target, we may not be able to implement security measures in a timely manner or, if and when implemented, we may not be able to determine the extent to which these measures could be circumvented. Any breaches that may occur could expose us to increased risk of lawsuits, regulatory penalties, loss of existing or potential customers, harm to our reputation and increases in our security costs, which could have a material adverse effect on our financial performance and operating results.

We have government customers, which subjects us to risks including early termination, audits, investigations, sanctions and penalties.

We derive some revenues from contracts with the U.S. government, state and local governments and foreign governments. Some of these customers may terminate all or part of their contracts at any time, without cause.

There is increased pressure for governments and their agencies, both domestically and internationally, to reduce spending. Some of our federal government contracts are subject to the approval of appropriations being made by the U.S. Congress to fund the expenditures under these contracts. Similarly, some of our contracts at the state and local levels are subject to government funding authorizations.

Additionally, government contracts are generally subject to audits and investigations which could result in various civil and criminal penalties and administrative sanctions, including termination of contracts, refund of a portion of fees received, forfeiture of profits, suspension of payments, fines and suspensions or debarment from future government business.

Because we depend on the development and growth of a balanced customer base, including key magnet customers, failure to attract, grow and retain this base of customers could harm our business and operating results.

Our ability to maximize revenues depends on our ability to develop and grow a balanced customer base, consisting of a variety of companies, including enterprises, cloud, digital content and financial companies, and network service providers. We consider certain of these customers to be key magnets in that they draw in other customers. The more balanced the customer base within each IBX data center, the better we will be able to generate significant interconnection revenues, which in turn increases our overall revenues. Our ability to attract customers to our IBX data centers will depend on a variety of factors, including the presence of multiple carriers, the mix of our offerings, the overall mix of customers, the presence of key customers attracting business through vertical market ecosystems, the IBX data center’s operating reliability and security and our ability to effectively market our offerings. However, some of our customers may face competitive pressures and may ultimately not be successful or may be consolidated through merger or acquisition. If these customers do not continue to use our IBX data centers it may be disruptive to our business. Finally, the uncertain economic climate may harm our ability to attract and retain customers if customers slow spending, or delay decision-making, on our offerings, or if customers begin to have difficulty paying us and we experience increased churn in our customer base. Any of these factors may hinder the development, growth and retention of a balanced customer base and adversely affect our business, financial condition and results of operations.

We may be subject to securities class action and other litigation, which may harm our business and results of operations.

We may be subject to securities class action or other litigation. For example, securities class action litigation has often been brought against a company following periods of volatility in the market price of its securities. Litigation can be lengthy, expensive, and divert management’s attention and resources. Results cannot be predicted with certainty and an adverse outcome in litigation could result in monetary damages or injunctive relief that could seriously harm our business, results of operations, financial condition or cash flows.

We may not be able to protect our intellectual property rights.

We cannot make assurances that the steps taken by us to protect our intellectual property rights will be adequate to deter misappropriation of proprietary information or that we will be able to detect unauthorized use and take appropriate steps to enforce our intellectual property rights. We also are subject to the risk of litigation alleging infringement of third-party intellectual property rights. Any such claims could require us to spend significant sums in litigation, pay damages, develop non-infringing intellectual property, or acquire licenses to the intellectual property that is the subject of the alleged infringement.

Government regulation may adversely affect our business.

Various laws and governmental regulations, both in the U.S. and abroad, governing Internet related services, related communications services and information technologies remain largely unsettled, even in areas where there has been some legislative action. For example, the Federal Communications Commission recently adopted new network neutrality rules that may result in material changes in the regulations and contribution regime affecting us and our customers. Likewise, as part of a review of the current equity market structure, the Securities and Exchange Commission and the Commodity Futures Trading Commission (“CFTC”) have both sought comments regarding the regulation of independent data centers, such as us, which provide colocation for

financial markets and exchanges. The CFTC is also considering regulation of companies that use automated and high-frequency trading systems. Any such regulation may ultimately affect our provision of offerings.

It also may take years to determine whether and how existing laws, such as those governing intellectual property, privacy, libel, telecommunications services and taxation, apply to the Internet and to related offerings such as ours, and substantial resources may be required to comply with regulations or bring any non-compliant business practices into compliance with such regulations. In addition, the development of the market for online commerce and the displacement of traditional telephony service by the Internet and related communications services may prompt an increased call for more stringent consumer protection laws or other regulation both in the U.S. and abroad that may impose additional burdens on companies conducting business online and their service providers.

The adoption, or modification of laws or regulations relating to the Internet and our business, or interpretations of existing laws, could have a material adverse effect on our business, financial condition and results of operations.

Industry consolidation may have a negative impact on our business model.

If customers combine businesses, they may require less colocation space, which could lead to churn in our customer base. Regional competitors may also consolidate to become a global competitor. Consolidation of our customers and/or our competitors may present a risk to our business model and have a negative impact on our revenues.

Terrorist activity throughout the world and military action to counter terrorism could adversely impact our business.

The continued threat of terrorist activity and other acts of war or hostility contribute to a climate of political and economic uncertainty. Due to existing or developing circumstances, we may need to incur additional costs in the future to provide enhanced security, including cybersecurity, which would have a material adverse effect on our business and results of operations. These circumstances may also adversely affect our ability to attract and retain customers, our ability to raise capital and the operation and maintenance of our IBX data centers.

We have various mechanisms in place that may discourage takeover attempts.

Certain provisions of our certificate of incorporation and bylaws may discourage, delay or prevent a third party from acquiring control of us in a merger, acquisition or similar transaction that a stockholder may consider favorable. Such provisions include:

In addition, Section 203 of the Delaware General Corporation Law, which restricts certain business combinations with interested stockholders in certain situations, may also discourage, delay or prevent someone from acquiring or merging with us.

PART II

Our common stock is quoted on the NASDAQ Global Select Market under the symbol of “EQIX.” Our common stock began trading in August 2000. The following table sets forth on a per share basis the low and high closing prices of our common stock as reported by the NASDAQ Global Select Market during the last two years.

As of January 31, 2015, we had 56,473,723 shares of our common stock outstanding held by approximately 191 registered holders.

In October 2014, our Board of Directors declared a special distribution of $416.0 million, or approximately $7.57 per share (the “2014 Special Distribution”), to our common stockholders in connection with our plan to convert to a REIT. The 2014 Special Distribution was paid on November 25, 2014 to our common stockholders of record as of the close of business on October 27, 2014. Common stockholders had the option to elect to receive payment of the 2014 Special Distribution in the form of stock or cash, with the total cash payment to all stockholders limited to no more than 20% of the total distribution. The number of shares distributed was determined based upon common stockholder elections and the average closing price of our common stock on the three trading days commencing on November 18, 2014 or $224.45 per share. As such, we issued 1,482,419 shares of our common stock and paid $83.3 million in connection with the 2014 Special Distribution.

To date, we have not declared or paid any regular cash dividends on our common stock. However, in connection with our conversion to a REIT effective January 1, 2015, we expect to begin paying quarterly dividends in 2015, beginning with our recently announced cash dividend of $1.69 per share payable on March 25, 2015.

In addition, we intend to declare one or more 2015 Special Distributions, which would encompass some extraordinary items of taxable income that we expect to recognize in 2015, such as depreciation recapture in respect of accounting method changes commenced in our pre-REIT period as well as foreign earnings and profits recognized as dividend income. We estimate the aggregate amount of our Special Distributions in both Year 2014 and Year 2015 together with the expected value of the deemed distributions associated with the Conversion Rate Adjustments, will equal approximately $1.0 to $1.1 billion. We expect to pay the 2015 Special Distributions in a combination of our common stock and cash, with at least 80% of the total 2015 Special Distributions in the form of common stock and up to 20% in cash. The conversion of our existing data center operations into the REIT and the addition of new entities into the REIT may also result in future special distributions.

During the year ended December 31, 2014, we did not issue or sell any securities on an unregistered basis.

Purchases of Equity Securities by Issuer

In December 2013, our Board of Directors approved a share repurchase program to repurchase up to $500.0 million in value of our common stock in the open market or private transactions through December 31, 2014. There were no share repurchases during the three months ended December 31, 2014. The share repurchase program expired on December 31, 2014 with an unused balance under the share repurchase program of $153.2 million.
