All statements in this discussion that are not historical are forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, including statements regarding Equinix’s “expectations”, “beliefs”, “hopes”, “intentions”, “strategies” or the like. Such statements are based on management’s current expectations and are subject to a number of factors and uncertainties that could cause actual results to differ materially from those described in the forward-looking statements. Equinix cautions investors that there can be no assurance that actual results or business conditions will not differ materially from those projected or suggested in such forward-looking statements as a result of various factors, including, but not limited to, the risk factors discussed in this Annual Report on Form 10-K. Equinix expressly disclaims any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements contained herein to reflect any change in Equinix’s expectations with regard thereto or any change in events, conditions, or circumstances on which any such statements are based.

Overview

Equinix provides network neutral colocation, interconnection and managed services to enterprises, content companies, systems integrators and the world’s largest networks. Through our 14 Internet Business Exchange hubs, or IBX hubs, in the U.S. and Asia customers can directly interconnect with each other for critical traffic exchange requirements. Direct interconnection to our aggregation of networks, which serve more than 90% of the world’s Internet routes, allows our customers to increase performance while significantly reducing costs. Based on our network neutral model and the quality of our IBX hubs, we believe we have established a critical mass of customers. This critical mass and the resulting “network effect,” combined with our improved financial position gained through the completion of a series of financing transactions over the past 15 months, has allowed us to accelerate new customer growth and bookings. As a result of our fixed cost model, we believe this continued growth will drive higher incremental margins and increasing cash returns.

Our network neutral business model is a key differentiator for Equinix in the market. Because we do not operate a network, we are able to offer direct interconnection to the largest aggregation of bandwidth providers and Internet service providers. The world’s top tier Internet service providers, and numerous access networks, second tier providers and international carriers such AT&T, British Telecom, Cable & Wireless, Level 3, MCI, NTT, SBC, SingTel, Sprint and Qwest are all currently located at our IBX hubs. Access to such a wide variety of networks has attracted 8 of the top 10 Internet properties and numerous other customers, including Amazon.com, Electronic Arts, Electronic Data Systems, Fujitsu, Gannett, Google, Hallmark, IBM, MSN, Sony, Ticketmaster, Washington Post and Yahoo!.

Our products and services are comprised of three types: Colocation, Interconnection, and Managed IT Infrastructure services.

This market has historically been served by large telecommunications carriers who have bundled their telecommunications services with their colocation offerings. In mid-2003 two major telecommunications companies announced their plans to exit the U.S. market in order to focus on their core offerings. The majority of the assets from these companies have been sold to managed service providers and we believe we will continue to benefit from gaining customers who are displaced or choose to leave these providers because we offer access to a

world-class choice of carriers and service providers. In December 2003, Equinix acquired a new IBX in Santa Clara, California, which will provide additional options to our customers in the Silicon Valley market. Strategically, Equinix will continue to look at attractive opportunities to grow our market share and selectively improve our footprint and service streams.

Recent Developments

Follow-on Equity Offering.    On November 21, 2003, we sold 5,524,780 shares of our common stock at a purchase price of $20.00 per share which resulted in gross proceeds to the Company of $110,495,600 before deducting offering expenses and underwriting fees.

Convertible Subordinated Debenture Offering.    On February 11, 2004, we sold $75.0 million in aggregate principal of 2.5% convertible subordinated debentures due 2024 to qualified institutional buyers. Subsequently, on February 18, 2004, we sold an additional $11.25 million of our debentures to the initial purchasers of these debentures. We used the net proceeds from this offering to repay all amounts outstanding under our credit facility and two of our other debt facilities. In addition, we intend to use the proceeds received to redeem our 13% senior notes. We have exercised our right to redeem all of our 13% senior notes, which have a total of $30.5 million of principal outstanding and have sent a notice of redemption to the trustee. The effective date of the redemption is expected to be March 12, 2004. Lastly, all remaining proceeds will be used for general corporate purposes.

Industry Background

The Internet is a collection of numerous independent networks interconnected with each other 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 user of the Internet sends an email to another user, assuming that each person uses a different network provider, the email must pass from one network to the other in order to get to the final destination.

In order to accommodate the rapid growth of Internet traffic, an organized approach for network interconnection was needed. 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 for free. 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 MCI), Sprint, Ameritech and Pacific Bell (both now known as SBC).

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 Microsoft, Yahoo!, America Online and others. In addition, the providers, as well as a growing number of enterprises required a more secure, reliable solution for direct connection to a variety of telecommunications networks as the importance of their Internet operations continued to grow.

To accommodate Internet traffic growth, the largest of these networks left the NAPs and began trading traffic by placing private circuits between each other. Peering which once occurred at the NAP locations were moved to these private circuits. Over the years, these circuits became expensive to expand and could not be built fast enough to accommodate the growth in traffic. This led to a need by the large carriers to find a more efficient way to trade traffic or peer. Customers have chosen Equinix for their peering operations because they are now able to reach all of the networks they peer with all in one location, with simple direct connections. Their ability to peer across the room, instead of across a metro area has increased the scalability of their operations while decreasing cost by upwards of 50%.

Our IBX hubs are the next-generation interconnection points. They are designed to handle the scalability issues that exist between both large and small networks, as well as the interconnection between the emerging companies who have become critical to the Internet. We have been successful in uniting the major companies that make up the Internet infrastructure including AT&T, Cable & Wireless, Level 3, MCI, Qwest and Sprint. These companies, which constitute the world’s largest top Internet service providers, together with most of the major broadband networks, including America Online, Comcast Corporation, Cox Communications, MSN and SBC, second tier backbones such as Global Crossing, Verio and WilTel, top international telecommunications carriers, including Bell Canada, British Telecom, Deutsche Telecom, France Telecom, Japan Telecom, KDDI, SingTel, StarHub, Telia and Telstra, and almost every fiber, sonet, Ethernet and competitive local exchange company, including Looking Glass Networks and OnFiber Communications, and incumbent local exchange company, including SBC and Verizon, are our customers and use us to interconnect with each other and their customers. Additionally, we provide an important industry leadership role in the area of exchange points and are consistently looked to as an industry expert and key influence in this subject matter.

Content providers and enterprises can now control their own network performance and destiny by choosing the various service providers they wish to work with and by establishing direct connections for this connectivity. For our customers, this represents significant cost savings and increased performance.

Our Solution

Our IBX hubs provide the environment and services to meet the networking and IT operations challenges facing enterprises, networks and Internet businesses today. As a result, we are able to provide the following key benefits to our customers:

Quality.    Our IBX centers provide customers with a secure, high quality solution for their colocation needs. Enterprise and content companies have demanding requirements for data center uptime, security, power backup and other important attributes. We have designed our centers and processes to exceed the requirements for the most important financial institutions, government agencies and key enterprise brands such as Amazon.com, Hallmark, Macromedia, Sony and Ticketmaster. We have a track record of 99.9999% uptime and are continually testing and refining processes to ensure that we will continue to provide the stability and quality that customers expect.

Performance.    Because we provide direct access to the providers that serve more than 90% of the world’s Internet networks and users, customers can quickly, efficiently, cost-effectively and reliably exchange traffic with their network services providers for higher performance operations. Access to the more than 170 networks ensures high-quality interconnection. With the mass of networks present, global enterprises are increasingly looking at ways to provide network diversity and increase performance of their operations, and are utilizing our IBX hubs to ensure their IT infrastructures are operating at the interconnection hub of the Internet. By using multiple networks, customers are able to insure their operations in the event that one of their network service providers has a service interruption or restructuring in the business. The network service providers and geographic diversity we offer provides customers with the flexibility to enable the highest performing Internet operations.

Improved Economics.    Our U.S. services such as Equinix GigE Exchange and Equinix Internet Core Exchange facilitate peering and dramatically reduce costs for critical transit, peering and traffic exchange operations by eliminating the costs of private peering or local loops. Networks such as Comcast, British Telecom and SBC and content providers such as Electronic Arts, Google, MSN and Yahoo! can save between 20% to 40% of bandwidth costs through the traffic exchange services we offer. In addition, in both the U.S. and Asia-Pacific, content companies and enterprises can save significant bandwidth costs because the number of networks housed within Equinix competing for the traffic of these companies results in lower prices while increasing performance.

Access to International Markets.    We offer our network, content and enterprise customers a one-stop solution for their outsourced IT infrastructure needs in the U.S. and Asia-Pacific. This is especially important for U.S. enterprises who want to expand into Asia-Pacific, where the myriad of complexities for doing business in each country remains challenging. We offer a consistent standard of quality, a single contract and a single point of support for all our locations throughout the U.S. and Asia-Pacific.

Our Strategy

Our objective is to become the premier hub for critical Internet players, enterprises and government agencies to locate their Internet operations in order to gain maximum benefits from the choice of networks and partners in the most simple and efficient manner. Key components of our strategy include the following:

Continue to Build upon our Critical Mass of Network Providers and Content Companies, and Grow our Position within Enterprise and Government.    We have assembled a critical mass of premier network providers and content companies and have become one of the core hubs of the Internet. This critical mass is a key selling point since content companies want to connect with a diverse set of networks to provide the best connectivity to their end-customers, and network companies want to sell bandwidth to content customers and interconnect with other networks in the most efficient manner available. Currently, we have over 170 unique networks, including all of the top tier networks, allowing our customers to directly interconnect with providers that serve more than 90% of global Internet routes. We have a growing mass of key players in the enterprise sector, such as GE, Gannett, Goldman Sachs and others. Similarly, we have experienced increasing success in the government sector within defense and security. We expect these sectors to contribute to our growth in 2004 and beyond.

Leverage the Network Effect.    As networks, content providers and other enterprises locate in our IBX hubs, it benefits their suppliers and business partners to do so as well to gain the full economic and performance benefits of direct interconnection. These partners, in turn, pull in their business partners, creating a “network effect” of customer adoption. Our interconnection services enable scalable, reliable and cost-effective interconnection and 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 Equinix in the market.

Promote our IBX Hubs as the Highest Performance Points on the Internet.    Our premier IBX hubs offer state of the art design and security, 24 hour / 365 days a year customer service, and high quality power and back-up redundancy with 99.9999% uptime. Underscoring our customer satisfaction, our embedded customer base has consistently provided 50% of our growth in a given quarter.

Provide New Products and Services within our IBX Hubs.    We will continue to offer additional products and services that are most valuable to our customers as they manage their Internet and network businesses and, specifically, as they attempt to effectively utilize multiple networks. For example, we offer an automated service to allow customers to easily choose and provision multiple networks with a simple easy to use portal.

Customers

Our customers include carriers and other bandwidth providers, internet service providers, enterprises, content providers and system integrators. We offer each customer a choice of business partners and solutions based on their colocation, interconnection and managed IT service needs. As of December 31, 2003, we had 712 customers.

Typical customers in each category include the following:

Table of Contents

Customers typically sign renewable contracts of one or more years in length. Our single largest customer, IBM, represented approximately 15%, 20% and 15% of total revenues for the years ended December 31, 2003, 2002 and 2001, respectively. No other single customer accounted for more than 10% of revenues during this time.

Products and Services

Our products and services are comprised of three types: Colocation, Interconnection and Managed IT Infrastructure services.

Colocation Services

Our IBX hubs provide our customers with secure, reliable and fault-tolerant environments that are necessary for optimum Internet commerce interconnection. Our IBX hubs include multiple layers of physical security, scalable cabinet space availability, on-site trained staff 24 hours per day, 365 days per year, dedicated areas for customer care and equipment staging, redundant AC/DC power systems and multiple other redundant, fault-tolerant infrastructure systems. Some specifications or services provided may differ in our Asia-Pacific locations in order to properly meet the local needs of customers in those locations.

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

Cabinets.    Our customers have several choices for colocating their networking and server equipment. They can place the equipment in one of our shared or private cages or customize their space. As a customer’s colocation requirements increase, they can expand within their original cage or upgrade into a cage that meets their expanded requirements. Cabinets are priced with an initial installation fee and an ongoing recurring monthly charge.

Power.    We offer both AC and DC power circuits at various amperages and phases customized to a customer’s individual power requirements. Power is becoming an element of increasing importance in customers’ colocation decisions.

IBXflex.    This service allows customers to deploy mission-critical operations personnel and equipment on-site at our IBX hubs. Because of the close proximity to their end-users, 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 Services

Our interconnection services enable scalable, reliable and cost-effective interconnection and traffic exchange between all Equinix customers. These interconnection services are either on a one-to-one basis with direct cross connects or one-to-many through one of our peering services. In peering, we provide an important industry leadership role by acting as the relationship broker between parties who would like to interconnect within our IBX hubs. Our staff has held significant positions in the leading industry groups such as the North American Network Operators’ Group, or NANOG, and the Internet Engineering Task Force, or IETF, and bring a tremendous amount of knowledge to this area. Our staff have published industry-recognized white papers and strategy documents in the areas of peering and interconnection, many of which are used by leading institutions worldwide in furthering the education and promotion of this important network arena. To showcase these efforts, we hold peering forums which are now widely recognized as a very influential forum for the world’s top peering experts. We will continue to develop additional services in the area of traffic exchange that will allow our

Table of Contents

customers to leverage the critical mass of networks now available in our IBX hubs. The current exchange services are comprised of the following:

Physical Cross-Connect/Direct Interconnections.    Customers needing to directly and privately connect to another IBX 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 services are priced with an initial installation fee and an ongoing monthly recurring charge.

Equinix Internet Core Exchange.    This interconnection service enables direct peering interconnections between major backbone networks and providers. Equinix Internet Core Exchange is a pre-provisioned interconnection package that enables major backbones to connect their networks directly in a centralized, neutral environment for peering and transit. The service includes pre-provisioned interconnections, premium service levels and specialized customer service features to support the quality and support levels required by the largest Internet providers in the world. Internet Core Exchange services are priced with an initial installation fee and an ongoing monthly recurring charge.

Equinix GigE Exchange.    Customers may choose to connect to our exchange central switching fabric rather than purchase a direct physical cross connection. With a connection to this switch, a customer can aggregate multiple interconnects over one physical connection instead of purchasing individual physical cross connects. The GigE Exchange service is offered as a bundled service that includes a cabinet, power, cross connects and port charges. The service is priced by IBX with an initial installation fee and an ongoing monthly recurring charge. Individual IBX prices scale upward based on the number of participants on the exchange service.

Internet Connectivity Services.    Customers who are installing equipment in our IBX hubs generally require IP connectivity or bandwidth services. Although it is often more beneficial for customers to go directly to the carriers, we will offer customers the ability to contract for these services through us from any of the major bandwidth providers. Customers who require a single bill and a single point of support for all of their services contract through Equinix for their bandwidth needs. We provide these services on a retail basis through each individual carrier and customer and do not aggregate this traffic or run a network. Internet Connectivity Services are priced with an initial installation fee and an ongoing monthly recurring charge based on the amount of bandwidth committed or used.

Managed IT Infrastructure Services

With the continued growth in Internet use, networks, service providers, enterprises and content providers are challenged to deliver fast and reliable service, while lowering costs. With over 170 ISPs and carriers located in our IBX hubs, we leverage the value of network choice with our set of multi-network management and other outsourced IT services.

Professional Services.    Our IBX hubs are staffed with Internet and telecommunications specialists who are on-site and available 24 hours per day, 365 days per year. These professionals are trained to perform installations of customer equipment and cabling. Professional services are custom-priced depending on customer requirements.

“Smart Hands” Services.    Our customers can take advantage of our professional “Smart Hands” service, which gives customers access to our IBX staff for a variety of tasks, when their own staff is not on site. These tasks may include equipment rebooting, power cycling, card swapping, and performing emergency equipment replacement. Services are available on-demand or by customer contract and are priced on an hourly basis.

Equinix Direct.    Equinix Direct is a managed multihoming service that allows customers to easily provision and manage multiple network connections over a single interface. Customers can choose branded networks on a monthly basis with no minimums or long-term commitments. This service is priced with an initial install fee and ongoing monthly recurring charges.

Equinix Mail Service.    Equinix’s enterprise messaging service is a complete outsourced solution, primarily based mainly on the Lotus Notes and Microsoft Exchange platform, which customers entrust the operation and support of their messaging applications. This service is currently only available in our Singapore location and the service is priced with an initial installation fee and an ongoing monthly recurring charge.

Managed Platform Solutions.    Managed Platform Solutions delivers pre-qualified, pre-installed, pre-hardened and fully managed systems platforms upon which customers can host their co-located applications. These platforms are available in different configuration to meet the needs of the customer. Each configuration includes the server(s), operating system, network connectivity, and system administration management as well as options for database and network administration. This service is only available in the Equinix Singapore location and the service is priced with an initial installation fee and an ongoing monthly recurring charge.

Sales and Marketing

Sales.    We use a direct sales force and channel marketing program to market our services to network, content provider, enterprise, government and Internet infrastructure businesses. We organize our sales force by customer segments 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 Asian-Pacific regional headquarters in Singapore. Our U.S. sales offices are located in New York; Reston, Virginia; Los Angeles; Honolulu; Dallas; Chicago and Silicon Valley. Our Asia-Pacific sales offices are located in Hong Kong, Tokyo, Singapore and Sydney.

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 hub participants encourage their customers, suppliers and business partners to come into the IBX hubs. These customers, suppliers and business partners, in turn, encourage their business partners to locate in IBX hubs resulting in additional customer growth. This network effect significantly reduces our new customer acquisition costs. In addition, large network providers or managed service providers may refer customers to Equinix as a part of their total customer solution.

Marketing.    To support our sales effort and to actively promote our brand in the U.S. and Asia-Pacific, we conduct comprehensive marketing programs. Our marketing strategies include an active public relations campaign and on-going 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, computer and financial industry conferences and place our officers and employees in keynote speaking engagements at these conferences. In addition to these activities, we build recognition through sponsoring or leading industry technical forums and participating in Internet industry standard-setting bodies. We continue to develop and host the industry’s most successful educational forums focused on peering technologies and peering practices for ISPs and content providers.

Competition

Our current and potential competition includes:

Table of Contents

Unlike other providers whose core businesses are bandwidth or managed services, we focus on neutral hubs for networks, content providers, enterprises and government. As a result, we are free of the channel conflict common at other hosting/colocation companies. We compete based on the quality of our facilities, our ability to provide a one-stop solution in our U.S. and Asia-Pacific locations, the superior performance and diversity of our network neutral strategy and the economic benefits of the aggregation of top networks and Internet businesses under one roof. Specifically, we have established relationships with a number of leading hosting companies such as IBM (our largest customer) and EDS. We expect to continue to benefit from several industry trends including the consolidation of supply in the colocation market, the need for contracting with multiple networks due to the uncertainty in the telecommunications market and the continued growth of the large and stable systems integrators.

Employees

As of December 31, 2003, we had 431 employees. We had 289 employees based in the U.S. and 142 employees based in Asia-Pacific. Of our U.S. employees, we had 178 based at our corporate headquarters in Foster City, California and our regional sales offices. Of those employees, 73 were in engineering and operations, 61 were in sales and marketing and 44 were in management and finance. We had 111 employees based at our IBX hubs in Washington, D.C.; New York, New York; Dallas, Texas; Chicago, Illinois; Los Angeles, California; Honolulu, Hawaii and the Silicon Valley area. Of our Asia-Pacific employees, we had 86 at our Asia-Pacific headquarters in Singapore and our other regional offices. Of those employees, 19 were in engineering and operations, 27 were in sales and marketing and 40 were in management and finance.

ITEM 2.    PROPERTIES

Our executive offices are located in Foster City, California, and we also have sales offices in several cities throughout the United States. Our Asia-Pacific headquarter office is located in Singapore and we also have some office space in Tokyo, Japan and Hong Kong, China. We have entered into leases for IBX hubs in Ashburn, Virginia; Newark and Secaucus, New Jersey; San Jose, Santa Clara and Los Angeles, California; Chicago, Illinois; Dallas, Texas; Honolulu, Hawaii; Tokyo, Japan; Hong Kong, China; Sydney, Australia and Singapore. We also hold a ground leasehold interest in certain unimproved real property in San Jose, California, consisting of approximately 40 acres.

ITEM 3.    LEGAL PROCEEDINGS

On July 30, 2001 and August 8, 2001, putative shareholder class action lawsuits were filed against us, certain of our officers and directors, and several investment banks that were underwriters of our initial public offering. The cases were filed in the United States District Court for the Southern District of New York, purportedly on behalf of investors who purchased our stock between August 10, 2000 and December 6, 2000. The suits allege that the underwriter defendants agreed to allocate stock in our initial public offering to certain investors in exchange for excessive and undisclosed commissions and agreements by those investors to make additional purchases in the aftermarket at pre-determined prices. The plaintiffs allege that the prospectus for our initial public offering was false and misleading and in violation of the securities laws because it did not disclose these arrangements. It is possible that additional similar complaints may also be filed. In July 2003, a Special Litigation Committee of the Equinix Board of Directors agreed to participate in a settlement with the plaintiffs that are anticipated to include most of the approximately 300 defendants in similar actions. This settlement agreement is subject to court approval and sufficient participation by all defendants in similar actions. Such settlement includes without limitation a guarantee of payments to the plaintiffs in the lawsuits, assignment of certain claims against the underwriters in our IPO to the plaintiffs, and a dismissal of all claims against Equinix and related individuals. Other than legal fees incurred to date, Equinix expects that all expenses of settlement, if any, will be paid by our insurance carriers. Until such settlement is finalized, we and our officers and directors intend to continue to defend the actions vigorously.

The Company has reserved 1,493,961 shares of common stock for issuance under the 2001 Supplemental Stock Plan. Nonstatutory options and restricted stock awards may be granted under the 2001 Supplemental Stock Plan to employees of the Company (or any parent or subsidiary corporation) who are neither officers nor Board members at the time of grant or to consultants. All option grants will have an exercise price per share equal to not less than 85% of the fair market value per share of common stock on the grant date. Each option will vest in installments over the optionee’s period of service with the Company. The purchase price for newly issued restricted shares awarded under the 2001 Supplemental Stock Plan may be paid in cash, by promissory note or by the rendering of past or future services. As of December 31, 2003, options covering 62,115 shares of common stock were outstanding under the 2001 Supplemental Stock Plan, 1,390,977 shares remained available for future option grants, and options covering 40,869 shares had been exercised. The options will vest on an accelerated basis in the event the Company is acquired and those options are not assumed or replaced by the acquiring entity. An option or award will become fully exercisable or fully vested if the holder’s employment or service is involuntarily terminated within 18 months following the acquisition. The Board may amend or terminate the 2001 Supplemental Stock Plan at any time. The 2001 Supplemental Stock Plan will continue in effect indefinitely unless the board decides to terminate the plan earlier.

Overview

Equinix provides network neutral colocation, interconnection and managed services to enterprises, content companies and systems integrators and the world’s largest networks. Through our 14 IBX hubs in the U.S. and Asia, customers can directly interconnect with each other for critical traffic exchange requirements. As of December 31, 2003, we had IBX hubs totaling an aggregate of more than 1.2 million gross square feet in the Washington, D.C., New York, Dallas, Chicago, Los Angeles, Honolulu and Silicon Valley areas in the United States and Hong Kong, Singapore, Sydney and Tokyo in the Asia-Pacific region.

In our IBX hubs, customers can directly interconnect with each other for critical traffic exchange requirements. Direct interconnection to our aggregation of networks, which serve more than 90% of the world’s Internet routes, allows our customers to increase performance while significantly reducing costs. Based on our network neutral model and the quality of our IBX hubs, we believe we have established a critical mass of customers, comprised of networks, content providers and other enterprise companies. As more customers locate in our IBX hubs, it benefits their suppliers and business partners to do so as well to gain the full economic and performance benefits of direct interconnection. These partners, in turn, pull in their business partners, creating a “network effect” of customer adoption. Our interconnection services enable scalable, reliable and cost-effective interconnection and traffic exchange thus lowering overall cost and increasing flexibility.

This critical mass of customers and the resulting network effect, combined with our improved financial position gained through the completion of a series of financing transactions at the end of 2002, our follow-on equity offering in November 2003 and our convertible debenture offering in February 2004 (refer to “Recent Developments” below), has resulted in an acceleration of new customer growth and related revenue bookings. Both our existing and new customers continue to gain confidence in our financial stability, which helps make their decision easier to move their core infrastructure into our IBX hubs. While we had generated negative operating cashflow in each annual period since inception, commencing the quarter ended September 30, 2003 we started to generate positive operating cash flow. During this quarter, our recurring revenues grew to a level sufficient to meet our operating cash requirements related to our predominantly fixed cost structure. We considered this quarter to be the inflection point in our business model whereby our revenues were sufficient on an ongoing basis to meet all our operating costs and working capital requirements. Given a large component of our cost of revenues are fixed in nature, we anticipate any growth in revenues will have a significant incremental flow through to gross profit in the 70 – 90% range. As a result of reaching this point in our operating history, we expect to generate cash from our operations during 2004 and expect these operating cash flows to also be sufficient to meet our cash requirements to fund our capital expenditures.

Historically, our market has been served by large telecommunications carriers who have bundled their telecommunication products and services with their colocation offerings. During 2003, a number of these

15

Table of Contents

telecommunication carriers reduced their colocation footprint as they exited under-performing markets. In addition, one major telecommunications company, Sprint, announced their plans to exit the colocation and hosting market altogether to focus on their core service offerings, while another telecommunications company, Cable & Wireless Plc, sold their U.S. assets to another telecommunications company, Savvis Communications Corp, in a bankruptcy auction. Each of these colocation providers owns and operates a network. We do not operate a network, yet have greater than 170 networks operating out of our IBX hubs. As a result, we are able to offer our customers a substantial choice of networks given our network neutrality allowing our customers to choose from numerous network service providers thereby eliminating a single point of failure. We believe this is a distinct advantage we have over our telecommunications company competitors, especially when the telecommunications industry is experiencing so many business challenges and changes as evidenced by the numerous bankruptcies and consolidations within this industry during the past several years. Furthermore, for those customers who do require a fully managed solution that these telecommunications companies typically provide, certain of our other customers, such as IBM and EDS, can provide such a solution within our network rich IBX hubs.

Strategically, we will continue to look at attractive opportunities to grow our market share and selectively improve our footprint and service streams, such as our recent acquisition of the Sprint property in Santa Clara (refer to “Recent Developments” below). However, we will continue to be very selective with any similar opportunity. As was the case with the Sprint property, the criteria will be quality of the design, access to networks, capacity availability in current market location, amount of incremental investment in the targeted property, lead-time to breakeven and in-place customers. Like the Sprint property, the right combination of these factors may be quite attractive for us. Dependent on the particular deal, these acquisitions may require additional capital expenditures in order to bring these centers up to Equinix standards.

Recent Developments

On November 21, 2003, we sold 5.5 million shares of our common stock at a purchase price of $20.00 per share, which resulted in net proceeds to the Company of $104.4 million. We refer to this transaction as the “follow-on equity offering.” In addition, in conjunction with our follow-on equity offering, we received consent from our senior lenders to amend the terms of our credit facility and permanently repaid $55.2 million of the then outstanding principal balance of $90.5 million.

On December 1, 2003, we closed a definitive agreement to sublease Sprint’s E|Solutions Internet Center in Santa Clara, California, and acquire certain related assets. The 160,000 square foot data center became our 14th IBX hub, expanding our global footprint to over 1.2 million square feet in eleven markets. Sprint’s Santa Clara center provides a physical infrastructure that is consistent with our industry leading standards, and currently hosts some of the top Internet companies. Consistent with our model of network-neutrality, we will offer a choice of networks in the new center.

On February 11, 2004, we sold $75.0 million in aggregate principal of 2.5% convertible subordinated debentures due 2024 to qualified institutional buyers. Subsequently, on February 18, 2004, we sold an additional $11.25 million of our debentures to the initial purchasers of these debentures. We used or intend to use the net proceeds from this offering to repay all amounts outstanding under our credit facility and two of our other debt facilities. In addition, we intend to use the proceeds received to redeem our 13% senior notes. We have exercised our right to redeem all of its 13% senior notes, which have a total of $30.5 million of principal outstanding and have sent a notice of redemption to the trustee. The effective date of the redemption is expected to be March 12, 2004. The redemption price for the senior notes will be equal to 106.5% of their principal amount plus accrued and unpaid interest to the redemption date. Lastly, all remaining proceeds will be used for general corporate purposes. We expect to record a significant loss on debt extinguishment during the quarter ended March 31, 2004, primarily related to the non-cash write-off of debt issuance costs and discounts in connection with these various debt repayments and redemptions, as well as the cash premium that we will pay on our 13% senior notes. We refer to this transaction as the “convertible debenture offering”.

The Combination, Financing, Senior Note Exchange and Crosslink Financing

In October 2002, we entered into agreements to consummate a series of related acquisition and financing transactions. These transactions closed on December 31, 2002. Under the terms of these agreements, we combined our business with two similar businesses, that of i-STT Pte Ltd, or i-STT, and Pihana Pacific, Inc., or Pihana. i-STT’s business was based in Singapore, with operations in Singapore and a joint venture in Thailand. Pihana’s business was based in Hawaii, with operations in Honolulu, Los Angeles, Hong Kong, Singapore, Tokyo and Sydney. In connection with the acquisition of i-STT and Pihana, we issued approximately 3.5 million shares of our common stock and approximately 1.9 million shares of our Series A preferred stock. We refer to this transaction as the “combination.” In conjunction with the combination, we issued to i-STT’s former parent company, STT Communications Ltd., or STT Communications, a $30.0 million convertible secured note in exchange for cash. We refer to this transaction as the “financing.”

In connection with the combination and financing, we amended the terms of the indenture governing our senior notes and extinguished $116.8 million of our senior notes in exchange for a combination of 1.9 million shares of our common stock and $15.2 million of cash. We refer to this transaction as the “senior note exchange.” Because we extinguished the debt in the senior note exchange at a significant discount, we recognized a substantial gain on debt extinguishment during the fourth quarter of 2002.

Furthermore, in conjunction with the combination, financing and senior note exchange, we amended our credit facility, and on December 31, 2002, we completed a 32 for 1 reverse stock split of our common stock in order to comply with Nasdaq initial listing requirements. Unless otherwise noted, all share and per share amounts in this prospectus supplement have been adjusted to give effect to the reverse stock split.

In April 2003, Equinix and certain of our subsidiaries and STT Communications entered into agreements with various entities affiliated with Crosslink Capital for a $10.0 million cash investment in Equinix in the form of additional convertible secured notes. This transaction closed in June 2003. We refer to this transaction as the “Crosslink financing.”

Critical Accounting Policies and Estimates

The preparation of our financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an on-going basis, management evaluates its estimates and judgments. Management bases its estimates and judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Management believes the following critical accounting policies, among others, affect its more significant judgments and estimates used in the preparation of its consolidated financial statements:

Revenue Recognition and Allowance for Doubtful Accounts.    We derive more than 90% of our revenues from recurring revenue streams, consisting primarily of (i) colocation services, such as the licensing of cabinet

17

Table of Contents

space, power and bandwidth; (ii) interconnection services, such as cross connects and Gigabit Ethernet Ports; and (iii) managed infrastructure services, such as Equinix Direct and various other e-business services such as mail service and managed platform solutions. The remainder of our revenues are from non-recurring revenue streams, such as from the recognized portion of deferred installation, professional services, contract settlements and equipment sales. Revenues from recurring revenue streams are billed monthly and recognized ratably over the term of the contract, generally one to three years. Fees for the provision of e-business services are recognized progressively as the services are rendered in accordance with the contract terms, except where the future costs cannot be reliably estimated, in which case fees are recognized upon the completion of services. Non-recurring installation fees are deferred and recognized ratably over the term of the related contract. Professional service fees are recognized in the period in which the services were provided and represent the culmination of the earnings process. Revenue from bandwidth and equipment is recognized on a gross basis in accordance with Emerging Issues Task Force, or EITF, Abstract No. 99-19, “Recording Revenue as a Principal versus Net as an Agent”, primarily because we act as the principal in the transaction, take title to products and services and bear inventory and credit risk. Revenue from contract settlements is recognized on a cash basis when no remaining performance obligations exist.

In some cases, we guarantee certain service levels, such as uptime, as outlined in individual customer contracts. To the extent that these service levels are not achieved, we reduce revenue for any credits given to the customer as a result. We generally have the ability to determine such service level credits prior to the associated revenue being recognized, and historically, these credits have not been significant.

Revenue is recognized only when the service is provided and when there is persuasive evidence of an arrangement, the fee is fixed or determinable and collection of the receivable is reasonably assured. It is customary business practice to obtain a signed master sales agreement and sales order prior to recognizing revenue in an arrangement. We assess the probability of collection based on a number of factors, including past transaction history with the customer and the credit-worthiness of the customer. We generally do not request collateral from our customers. If we determine that collection of a fee is not reasonably assured, we defer the fee and recognize revenue at the time collection becomes reasonably assured, which is generally upon receipt of cash. In addition, we also maintain an allowance for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments for those customers that we had expected to collect the revenues. If the financial condition of our customers were to deteriorate or if they become insolvent, resulting in an impairment of their ability to make payments, allowances for doubtful accounts may be required. Management specifically analyzes accounts receivable and current economic news and trends, historical bad debts, customer concentrations, customer credit-worthiness and changes in customer payment terms when evaluating revenue recognition and the adequacy of our reserves.

Our customer base has historically been composed of businesses throughout the U.S. Commencing in fiscal year 2003, our revenues include revenues from our newly-acquired Asia-Pacific operations. For the year ended December 31, 2003 our revenues were split approximately 85% in the U.S. and 15% in Asia-Pacific. We perform ongoing credit evaluations of our customers. As of December 31, 2003, one customer, IBM, accounted for 15% of annual revenues and 11% of accounts receivable. As of December 31, 2002, this same customer accounted for 20% of annual revenues and 15% of accounts receivable. No other single customer accounted for greater than 10% of accounts receivable or annual revenues for the periods presented.

Accounting for Income Taxes.    Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts that are expected more likely than not to be realized.

18

Table of Contents

We currently have provided for a full valuation allowance against our net deferred tax assets and our net operating losses. We have considered future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance. Based on the available objective evidence, management does not believe that the net deferred tax assets will be fully realizable. Should we determine that we would be able to realize our deferred tax assets in the foreseeable future, a reversed adjustment to the valuation allowance would increase income in the period such determination is made.

Estimated and Contingent Liabilities.    Management estimates exposure on certain liabilities and contingent liabilities, such as property taxes and litigation, based on the best information available at the time of determination. With respect to real and personal property taxes, management records what it can reasonably estimate based on prior payment history, current landlord estimates or estimates based on current or changing fixed asset values in each specific municipality, as applicable. However, there are circumstances beyond our control whereby the underlying value of the property or basis for which the tax is calculated on said property may change, such as a landlord selling the underlying property of one of our IBX hub leases or a municipality changing the assessment value in a jurisdiction and, as a result, our property tax obligations may vary from period to period. Based upon the most current facts and circumstances, we make the necessary property tax accruals for each of our reporting periods. However, revisions in our estimates of the potential or actual liability could materially impact our results of operation and financial position.

For litigation claims, when management can reasonably estimate the range of loss and when an unfavorable outcome is probable, a contingent liability is recorded. For current legal proceedings, management believes that it has adequate legal defenses and that the ultimate outcome of these actions will not have a material effect on the Company’s financial position, results of operations and cashflows. Furthermore, because of the uncertainties as to the outcome of these proceedings and since no range of loss can be estimated at this time, management has determined that no accrual is needed. As additional information becomes available, we will assess the potential liability related to our pending litigation and revise our estimates. Revisions in our estimates of the potential liability could materially impact our results of operation and financial position.

Accounting for Property and Equipment.    Property and equipment are stated at original cost, or in the case of IBX hubs that we acquire, at fair value at the time of acquisition. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets, generally two to five years for non-IBX hub equipment and seven to ten years for IBX hub equipment. Leasehold improvements and assets acquired under capital lease are amortized over the shorter of the lease term or the estimated useful life of the asset or improvement.

Should management determine that the actual useful lives of our property and equipment placed into service is less than originally anticipated, or if any of our property and equipment was deemed to have incurred an impairment, additional depreciation, or an impairment charge would be required, which would decrease net income in the period such determination was made. Conversely, should management determine that the actual useful lives of its property and equipment placed into service was greater than originally anticipated, less depreciation may be required, which would increase net income in the period such determination was made.

Impairment of Long-Lived Assets.    We account for the impairment of long-lived assets in accordance with Statement of Financial Accounting Standard, or SFAS, No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets”, or in the case of goodwill, in accordance with SFAS No. 142, “Goodwill and Other Intangible Assets”. We evaluate the carrying value of our long-lived assets, consisting primarily of our IBX hubs and goodwill, whenever certain events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable or at least on an annual basis during the fourth quarter for goodwill. Such events or circumstances include, but are not limited to, a prolonged industry downturn, a significant decline in our market value or significant reductions in projected future cash flows.

Significant judgments and assumptions are required in the forecast of future operating results used in the preparation of the estimated future cash flows, including profit margins, long-term forecasts of the amounts and

19

Table of Contents

timing of overall market growth and our percentage of that market, groupings of assets, discount rates and terminal growth rates. In addition, significant estimates and assumptions are required in the determination of the fair value of our tangible long-lived assets, including replacement cost, economic obsolescence, and the value that could be realized in orderly liquidation. Changes in these estimates could have a material adverse effect on the assessment of our long-lived assets, thereby requiring us to write down the assets. Our net long-lived assets as of December 31, 2003 and December 31, 2002, included property and equipment of $343.6 million and $390.0 million, respectively, and goodwill and other identifiable intangible assets of $23.5 million and $25.0 million, respectively.

Results of Operations

Years Ended December 31, 2003 and 2002

Revenues.    Our revenues for the year ended December 31, 2003 and 2002 were split between the following revenue classifications (dollars in thousands):

Our revenues for the year ended December 31, 2003 and 2002 were geographically comprised of the following (dollars in thousands):

We recognized revenues of $117.9 million for the year ended December 31, 2003, as compared to revenues of $77.2 million for the year ended December 31, 2002, a 53% increase. Included in revenues for the year ended December 31, 2003, are the results of the two companies that we acquired on December 31, 2002, i-STT and Pihana, totaling $23.4 million. We segment our business geographically between the U.S. and Asia-Pacific as further discussed below.

Our business is based on a recurring revenue model comprised of colocation, interconnection and managed infrastructure services. We consider these services as recurring as once a customer has been installed in one of our IBX hubs they are billed on a fixed and recurring basis each month for the duration of their contract, which is generally one to three years in length. Our recurring revenues are a significant component of our total revenues comprising 93% of our total revenues for the year ended December 31, 2003, an increase from the 85% level in the prior year. To review our revenue recognition policies for our recurring revenue streams, refer to “Critical Accounting Policies and Estimates” above.

Our non-recurring revenues are primarily comprised of installation services related to a customer’s initial deployment and, professional services that we perform. These services are considered to be non-recurring as they are billed typically once and only upon completion of the installation or professional services work performed.

20

Table of Contents

The non-recurring revenues are typically billed on the first invoice distributed to the customer. Installation and professional services revenues increased 53% year over year, primarily due to strong existing and new customer growth during the year. As a percent of total revenues, we expect non-recurring revenues to represent approximately 5% of total revenues in each year. Other non-recurring revenues include equipment resales and customer settlements. This non-recurring revenue line decreased significantly from the prior year as (i) we are no longer pursuing equipment resales due to their poor margin characteristics and (ii) the number of customer right-sizings and settlements decreased substantially during 2003. To review our revenue recognition policies for our non-recurring revenue streams, refer to “Critical Accounting Policies and Estimates” above.

In addition to reviewing recurring versus non-recurring revenues, we look at two other primary metrics when we analyze our revenues: 1) customer count and 2) percentage utilization. Our customer count increased to 712 as of December 31, 2003 versus 568 as of December 31, 2002, an increase of 25%. Our utilization rate represents the percentage of our cabinet space billing versus total cabinet space available. Our utilization rate as of December 31, 2003 was 37% versus 29% as of December 31, 2002, an increase of 28%, including our Asia-Pacific operations for both periods. Although we have substantial capacity for growth, our utilization rates vary from market to market among our 14 worldwide IBX hubs. We continue to monitor the available capacity in each of our selected markets. To the extent we have limited capacity available in a given market, it may limit our ability for growth in that market. Therefore, consistent with our acquisition of the Sprint’s Santa Clara property in December 2003, we will continue to review our available space in our other operating markets.

U.S. Revenues.    We recognized U.S. revenues of $99.7 million for the year ended December 31, 2003 as compared to $77.2 million for the year ended December 31, 2002. U.S. revenues consisted of recurring revenues of $93.6 million and $65.3 million, respectively, for the year ended December 31, 2003 and 2002, a 43% increase. U.S. recurring revenues consist primarily of colocation and interconnection services plus a nominal amount of managed infrastructure services. U.S. recurring revenues for the year ended December 31, 2003 includes $5.1 million of revenues generated from the two U.S. IBX hubs acquired from Pihana on December 31, 2002 located in Los Angeles and Honolulu. Excluding revenues from these acquired U.S. IBX hubs, the period over period growth in recurring revenues of 60% was primarily the result of an increase in orders from both our existing customers and new customer growth acquired during the year as reflected in the growth in our customer count and utilization rate as discussed above. In addition, consistent with the growth in our customer base, our interconnection revenues have grown as our customers continue to expand their interconnection activity with each other. As of December 31, 2003, U.S. interconnection revenue represented 21% of total U.S. recurring revenue as compared to 9% in the prior year. We expect our U.S. recurring revenues to continue to grow and remain our most significant source of revenue for the foreseeable future.

In addition, U.S. revenues consisted of non-recurring revenues of $6.1 million and $11.9 million, respectively, for the year ended December 31, 2003 and 2002. Non-recurring revenues are primarily related to the recognized portion of deferred installation, professional services, settlement fees associated with certain contract terminations and equipment resales. The period over period decrease in U.S. non-recurring revenues was primarily the result of $2.9 million of equipment resale revenue and $4.9 million in settlement fees from customers to terminate their contract recognized during the year ended December 31, 2002. There were no equipment resale transactions during the year ended December 31, 2003; however, we received $1.2 million of settlement fees during the year ended December 31, 2003, primarily as a result of bankruptcy related payments from both Worldcom and Excite@home. Excluding any settlement fees that we may recognize in the future, we expect our U.S. non-recurring revenues to remain relatively flat or grow moderately in the foreseeable future.

Asia-Pacific Revenues.    As a result of the combination that closed on December 31, 2002, which resulted in the acquisition of four Asia-Pacific IBX hubs, we recognized $18.2 million of revenues in Asia-Pacific during the year ended December 31, 2003. Prior to the combination we generated no revenues from outside of the United States. Asia-Pacific revenues consisted of recurring revenues of $16.3 million, primarily from colocation and managed infrastructure services, and non-recurring revenues of $1.9 million for the year ended December 31, 2003, which includes settlement fees of $584,000, primarily from one customer that terminated its contract. Asia- Pacific revenues are generated from Singapore, Tokyo, Hong Kong and Sydney with Singapore representing

21

Table of Contents

approximately 77% of the regional revenues. Our Asia-Pacific revenues are similar to the revenues that we generate from our U.S. IBX hubs; however, our Singapore IBX hub has additional managed infrastructure service revenue, such as mail service and managed platform solutions, which we do not currently offer in any other IBX hub location. We expect our Asia-Pacific revenues to decrease slightly during the first half of 2004 as we expect some churn on our low-margin bandwidth revenue in Singapore. However, excluding this expected drop in bandwidth revenue, we would otherwise expect our Asia-Pacific revenues to begin to grow over the course of the year.

Cost of Revenues.    Cost of revenues were $128.1 million for the year ended December 31, 2003 versus $104.1 million for the year ended December 31, 2002, a 23% increase. Included in cost of revenues for the year ended December 31, 2003 are the results of the two companies that we acquired on December 31, 2002, i-STT and Pihana, a cumulative total of $24.7 million. The largest cost components of our cost of revenues are depreciation, rental payments related to our leased IBX hubs, utility costs including bandwidth, IBX employees’ salaries and benefits, consumable supplies and equipment and security services. A substantial majority of our cost of revenues are fixed in nature and do not vary significantly from period to period. However, there are certain costs, which are considered variable in nature including utilities and consumable supplies that are directly related to growth of services in our existing and new customer base. Given a large component of our cost of revenues are fixed in nature, we anticipate any growth in revenues will have a significant incremental flow through to gross profit in the 70 – 90% range.

U.S. Cost of Revenues.    U.S. cost of revenues were $107.5 million for the year ended December 31, 2003 as compared to $104.1 million for the year ended December 31, 2002, a 3.2% increase. U.S. cost of revenues included $49.9 million and $47.8 million, respectively, of depreciation expense and $59,000 and $266,000, respectively, of stock-based compensation expense for the year ended December 31, 2003 and 2002. During the year ended December 31, 2003, we also recorded $562,000 of accretion expense associated with our asset retirement obligation relating to our various leaseholds, which consist primarily of our IBX hub operating leases, as required under FASB No. 143 that was adopted in 2003. Furthermore, U.S. cost of revenues included the costs associated with the $2.9 million of equipment resale revenue that we recorded for the year ended December 31, 2002, which was approximately $2.8 million. We recorded no equipment resale revenue for the year ended December 31, 2003. Included in the U.S. cost of revenues for the year ended December 31, 2003, were the operating costs associated with (i) the Los Angeles and Honolulu IBX hubs acquired from Pihana in the combination on December 31, 2002, which totaled $4.1 million ($3.5 million excluding depreciation) and (ii) the Santa Clara IBX hub acquired on December 1, 2003, which totaled $597,000. Excluding depreciation, stock-based compensation, accretion expense, the costs of equipment resales and the costs of operating the acquired U.S. IBX hubs, U.S. cash cost of revenues decreased period over period to $52.8 million for the year ended December 31, 2003 from $53.1 million for the year ended December 31, 2002, a 1% decrease. This decrease is primarily the result of reduced costs associated with the San Jose ground lease of $3.6 million as a result of the option that we exercised in September 2002 to return approximately one-half of the land commencing in October 2002 (refer to ‘Restructuring Charges” below); however, this decrease is partially offset by an increase in operating costs associated with certain of our IBX hubs as a result of (a) higher property taxes for certain IBX hubs and (b) increasing utility costs in line with increasing customer installations and revenues attributed to this customer growth. We continue to anticipate that our cost of revenues will increase in the foreseeable future as the occupancy levels in our U.S. IBX hubs increase, however as a percent of revenues, we anticipate our cost of revenues will continue to decline.

Asia-Pacific Cost of Revenues.    As a result of the combination that closed on December 31, 2002, which resulted in the acquisition of four Asia-Pacific IBX hubs, we incurred an additional $20.6 million in cost of revenues from our Asia-Pacific IBX hub operations during the year ended December 31, 2003. Included in this number is $4.4 million of depreciation expense. Excluding depreciation expense, our acquired cost of revenues totaled $16.2 million for Asia-Pacific. Our Asia-Pacific cost of revenues consist of the same type of costs that we incur in our U.S. IBX hub operations, namely rental payments for our leased IBX hubs, utility costs, site employees’ salaries and benefits, consumable supplies and equipment and security services. Our Asia-Pacific

costs of revenues are generated in Singapore, Tokyo, Hong Kong and Sydney. There are several managed IT infrastructure service revenue streams unique to our Singapore IBX hub, such as mail service and managed platform solutions, that are more labor intensive than our service offerings in the United States. As a result, our Singapore IBX hub has a greater number of employees than any of our other IBX hubs, and therefore, a greater labor cost relative to our other IBX hubs in the United States or other Asia-Pacific locations. We anticipate that our Asia-Pacific cost of revenues will experience a small decrease during the first half of 2004 as a result of the expected drop in low-margin bandwidth revenue as discussed above. However, excluding this, we would otherwise expect to see moderate growth in Asia-Pacific cost of revenues in the foreseeable future consistent with our anticipated growth in revenues over the course of the year.

Sales and Marketing.    Sales and marketing expenses increased to $19.5 million for the year ended December 31, 2003 from $15.2 million for the year ended December 31, 2002. Included in sales and marketing expenses for the year ended December 31, 2003, are the results of the two companies that we acquired on December 31, 2002, i-STT and Pihana, totaling $6.9 million.

U.S. Sales and Marketing Expenses.    U.S. sales and marketing expenses decreased to $12.5 million for the year ended December 31, 2003 as compared to $15.2 million for the year ended December 31, 2002. Included in U.S. sales and marketing expenses were $294,000 and $952,000, respectively, of stock-based compensation expense for the year ended December 31, 2003 and 2002. During the year ended December 31, 2002, we recorded $2.3 million in bad debt expense. The amount of bad debt expense that we recorded in the prior period, which was significantly larger than what we typically incur, was primarily the result of write-offs or full reserves of aged receivables associated with several customers, including Teleglobe, which had filed for bankruptcy under Chapter 11 of the U.S. Bankruptcy Code last year. Excluding stock-based compensation and bad debt expense, U.S. sales and marketing expenses increased to $12.4 million from $12.0 million, respectively, for the year ended December 31, 2003 and 2002, a 3% increase. Sales and marketing expenses consist primarily of compensation and related costs for sales and marketing personnel, sales commissions, marketing programs, public relations, promotional materials and travel. Excluding stock-based compensation and bad debt expense, the nominal increase in sales and marketing expenses year over year is primarily related to the incremental sales and marketing efforts associated with the two U.S. IBX hubs acquired in the combination as of December 31, 2002 in Los Angeles and Honolulu, as well as an overall increase in sales compensation due to increased revenues. We expect to see a nominal increase in sales and marketing spending in the future, although as a percent of revenues, we anticipate a decline in sales and marketing spending.

Asia-Pacific Sales and Marketing Expenses.    As a result of the combination that closed on December 31, 2002, we incurred an additional $6.9 million of sales and marketing expenses, comprised of $4.8 million in cash sales and marketing expenses from our Asia-Pacific operations during the year ended December 31, 2003, and $2.1 million of amortization expense. Our Asia-Pacific sales and marketing expenses consist of the same type of costs that we incur in our U.S. operations, namely compensation and related costs for sales and marketing personnel, sales commissions, marketing programs, public relations, promotional materials and travel. Our Asia-Pacific sales and marketing expenses are generated in Singapore, Tokyo, Hong Kong and Sydney. We expect that our Asia-Pacific sales and marketing expenses will remain relatively flat in the foreseeable future. As a result of the combination that closed on December 31, 2002, we acquired several intangible assets that we amortize, namely the use of a trade-name and certain customer contracts in Singapore valued at approximately $300,000 and $3.6 million, respectively. The trade-name intangible asset was being amortized over one year ending December 31, 2003 and the customer contract intangible asset is being amortized over two years, ending December 31, 2004. As a result, we incurred a total of $2.1 million of amortization expense during the year ended December 31, 2003.

General and Administrative.    General and administrative expenses increased to $34.3 million for the year ended December 31, 2003 from $30.7 million for the year ended December 31, 2002. Included in general and administrative expenses for the year ended December 31, 2003, are the results of the two companies that we acquired on December 31, 2002, i-STT and Pihana, totaling $7.5 million.

U.S. General and Administrative Expenses.    U.S. general and administrative expenses decreased to $28.3 million for the year ended December 31, 2003 as compared to $30.7 million for the year ended December 31, 2002. Included in U.S. general and administrative expenses were $5.3 million and $6.2 million, respectively, of depreciation expense and $2.6 million and $5.7 million, respectively, of stock-based compensation expense for the year ended December 31, 2003 and 2002. In addition, U.S. general and administrative expenses for the year ended December 31, 2003, included $1.5 million of costs associated with a corporate headquarter office acquired from Pihana on December 31, 2002 located in Honolulu. This office was closed as of June 30, 2003. Excluding depreciation, stock-based compensation expense and the costs of the acquired Honolulu office, U.S. general and administrative expenses remained relatively flat at $18.9 million for the year ended December 31, 2003, as compared to $18.8 million for the year ended December 31, 2002. General and administrative expenses, excluding depreciation and stock-based compensation, consist primarily of salaries and related expenses, accounting, legal and administrative expenses, professional service fees and other general corporate expenses such as our corporate headquarter office lease. We expect to see a nominal increase in general and administrative spending in the future, although as a percent of revenues, we anticipate a decline in general and administrative spending.

Asia-Pacific General and Administrative Expenses.    As a result of the combination that closed on December 31, 2002, we incurred an additional $6.0 million in general and administrative expenses from our newly-acquired Asia-Pacific operations. Our Asia-Pacific general and administrative expenses, which included $497,000 of depreciation expense, consist of the same type of costs that we incur in our U.S. operations, namely salaries and related expenses, accounting, legal and administrative expenses, professional service fees and other general corporate expenses. Our Asia-Pacific general and administrative expenses are generated in Singapore, Tokyo, Hong Kong and Sydney. Our Asia-Pacific headquarter office is located in Singapore. Most of the corporate overhead support functions that we have in the U.S. also reside in our Singapore office in order to support our Asia-Pacific operations. In addition, we have separate corporate office locations in Tokyo and Hong Kong. We expect that our Asia-Pacific general and administrative expenses will remain relatively flat or experience only moderate growth for the foreseeable future.

Restructuring Charges.    We did not incur any restructuring charges during the year ended December 31, 2003. During the year ended December 31, 2002, we recorded restructuring charges of $28.9 million. The restructuring charges consisted of (a) a $5.0 million option fee paid in May 2002 related to the amendment of our approximately 80 acre ground lease in San Jose, California from which we subsequently elected to exercise the option to permanently exclude 40 acres commencing October 1, 2002; (b) a partial write-off of two letters of credit totaling $19.0 million associated with the exercise in September 2002 of our option to permanently terminate approximately one-half of our lease obligations under the San Jose ground lease (c) a write-off of property and equipment of $2.6 million, primarily leasehold improvements and some equipment, located in two unnecessary U.S. IBX expansion and headquarter office space operating leaseholds we had decided to exit and that do not currently provide any ongoing benefit and (d) write-offs or accruals of certain U.S. or European exit costs and severance charges.

Interest Income.    Interest income decreased to $296,000 from $998,000 for the year ended December 31, 2003 and 2002, respectively. Interest income decreased due to lower average cash, cash equivalent and short-term investment balances held in interest-bearing accounts and lower interest rates received on those invested balances.

Interest Expense.    Interest expense decreased to $20.5 million from $35.1 million for the year ended December 31, 2003 and 2002, respectively. The significant decrease in interest expense was primarily attributable to the retirement of $169.5 million of our 13% senior notes during 2002. In addition, we reduced the interest expense attributed to our credit facility as a result of a reduction in the principal balance outstanding and a reduction in the interest rates. However, these interest expense savings were partially offset by the approximately $7.3 million of non-cash interest expense associated with the $30.0 million 14% convertible secured note issued on December 31, 2002 as a result of the financing, and the $10.0 million 10% convertible

24

Table of Contents

secured notes issued on June 5, 2003 as a result of the Crosslink financing. We recorded a substantial debt discount equal to the $10.0 million of principal in connection with the Crosslink financing, primarily as a result of the beneficial conversion feature associated with these convertible secured notes, which is being amortized to interest expense over the term of the Crosslink financing. This is a primary contributor to our increased non-cash interest expense from the prior period.

Gain on Debt Extinguishment.    During the year ended December 31, 2002, we retired approximately $169.5 million of senior notes in exchange for approximately 2.4 million shares of common stock and $17.7 million of cash. As a result, we recognized a $114.2 million net gain on debt extinguishment during 2002, after deducting transaction costs, interest waived and allocation of unamortized debt issuance costs and debt discount. Although we made payments on our various debt facilities during 2003, we extinguished no senior notes or other debt during the year ended December 31, 2003.

Income Taxes.    A full valuation allowance is recorded against our deferred tax assets as management cannot conclude, based on available objective evidence, when it is more likely than not that the gross value of its deferred tax assets will be realized.

Years Ended December 31, 2002 and 2001

Revenues.    We recognized revenues of $77.2 million for the year ended December 31, 2002, as compared to revenues of $63.4 million for the year ended December 31, 2001. Revenues consisted of recurring revenues of $65.3 million and $57.6 million, respectively, for the year ended December 31, 2002 and 2001, primarily from the leasing of cabinet space, power and cross connects. Non-recurring revenues were $11.9 million and $5.8 million, respectively, for the year ended December 31, 2002 and 2001, primarily related to the recognized portion of deferred installation revenue and custom service revenues and settlement fees associated with certain customer right-sizing or contract terminations. Settlement fees recognized during the year ended December 31, 2002 totaled approximately $4.5 million, including a $2.8 million one-time settlement with Qwest received in the third quarter of 2002, and approximately $562,000 for the corresponding period in 2001. Installation and service fees are recognized ratably over the term of the contract. Custom service revenues are recognized upon completion of the services. Settlement fees are recognized upon contract termination. In February and March 2002, we entered into equipment reseller agreements with two related party companies. Included within the $11.9 million of non-recurring revenues for the year ended December 31, 2002, were $2.9 million of equipment resales resulting from these two equipment reseller agreements. There were no equipment resales in the year ended December 31, 2001. Excluding equipment resales, we recognized revenues of $74.2 million for the year ended December 31, 2002 as compared to revenues of $63.4 million for the year ended December 31, 2001, a 17% increase.

The period over period growth in revenues was primarily the result of an increase in orders from existing customers and growth in our customer base from 218 customers as of December 31, 2001 to 303 customers as of December 31, 2002 on a pre-combination basis and settlement fees associated with certain customer right-sizing or contract terminations. However, this growth in our customer base was partially offset by a number of our larger customers reducing the size of their contractual commitments to us. We refer to this effort as the “right-sizing” of our larger customer contracts. During late 2001 and throughout 2002, we proactively worked with certain of our larger customers to right-size their contractual commitments to help them better react to a slowdown in customer demand as a result of weaker economic conditions. Although these right-sizing efforts often result in a reduction in the number of cabinets these customers are obligated to pay for, many of these right-sizing efforts have resulted in the customer extending the term for the remaining cabinets. As a result, although the short-term recurring revenues from such customers are reduced, the overall contract value at times remains intact and the relationship with the customer is preserved, if not improved. As of December 31, 2002, we had successfully completed the right-sizing of most of our customers that had more than 100 cabinets booked, a booking level that represents our larger customers. These right-sizing efforts were, throughout 2002, netted out against our new customer cabinet bookings, limiting our overall revenue growth during this period.

Commencing in fiscal 2003, our revenues included revenues from our newly-acquired Asia-Pacific operations. We expect that revenues commencing in 2003 will be split approximately 85% in the U.S. and 15% in Asia-Pacific.

Cost of Revenues.    Cost of revenues increased to $104.1 million for the year ended December 31, 2002 from $94.9 million for the year ended December 31, 2001. These amounts included $47.8 million and $40.0 million, respectively, of depreciation expense and $266,000 and $426,000, respectively, of stock-based compensation expense. In addition to depreciation and stock-based compensation, cost of revenues consists primarily of rental payments for our leased IBX hubs, site employees’ salaries and benefits, utility costs, power and redundancy system engineering support services and related costs and security services. Furthermore, cost of revenues for the year ended December 31, 2002 included the costs associated with $2.9 million in equipment sales we recorded, which was approximately $2.8 million. Excluding depreciation, stock-based compensation expense and the costs of equipment sales, cost of revenues decreased slightly period over period to $53.1 million for the year ended December 31, 2002 from $54.4 million for the year ended December 31, 2001, a 2% decrease.

Cost of revenues for the year ended December 31, 2001 included $5.0 million in costs related to our European expansion plans. Due to the restructuring charge that we recorded in the third quarter of 2001, these costs were not in our cash cost of revenues for the year ended December 31, 2002; however, these savings were partially offset by the additional costs incurred of $3.7 million from (a) our newest and largest IBX hub opened during the first quarter of 2002 in the New York metropolitan area and (b) the costs associated with the ramp-up of our existing IBX hubs. In September 2002, we exercised an option to reduce the monthly operating costs under the San Jose ground lease by approximately one-half commencing October 2002, which resulted in savings of approximately $1.1 million as compared to the prior year. We anticipate that the costs associated with the continued ramp-up of our IBX hubs and the additional costs associated with some of our new services, such as bandwidth, will continue to increase in the foreseeable future; however, the cost savings resulting from the elimination of approximately half of the San Jose ground lease costs, which commenced in October 2002, should offset most of these increases for the foreseeable future in the U.S. However, commencing in fiscal 2003, our cost of revenues included the cost of revenues associated with our Asia-Pacific operations.

Sales and Marketing.    Sales and marketing expenses decreased to $15.2 million for the year ended December 31, 2002 from $16.9 million for the year ended December 31, 2001. These amounts included $952,000 and $2.8 million, respectively, of stock-based compensation expense. In addition, we recorded $2.3 million in bad debt expense for the year ended December 31, 2002, as compared to $477,000 recorded in the prior year. This substantial increase in bad debt expense was primarily the result of full provisions against aged receivables associated with two customers, Teleglobe and WorldCom, both of which filed for bankruptcy protection under Chapter 11 of the U.S. Bankruptcy Code in 2002. Excluding stock-based compensation and bad debt expense, cash sales and marketing costs decreased to $12.0 million for the year ended December 31, 2002 from $13.6 million for the year ended December 31, 2001, a 12% decrease. Cash sales and marketing expenses consist primarily of compensation and related costs for sales and marketing personnel, sales commissions, marketing programs, public relations, promotional materials and travel. The decrease in sales and marketing expenses is the result of several cost saving initiatives that we undertook, including staff reductions of approximately 25% during 2001 that resulted in approximately $2.6 million in annual savings in sales and marketing costs and an overall decrease in discretionary spending. We continue to closely monitor our spending in all areas as a result of the current market conditions. However, commencing in fiscal 2003, our sales and marketing expenses included the sales and marketing expenses associated with our Asia-Pacific operations.

General and Administrative.    General and administrative expenses decreased to $30.7 million for the year ended December 31, 2002 from $58.3 million for the year ended December 31, 2001. These amounts included $5.7 million and $15.8 million, respectively, of stock-based compensation expense and $6.2 million and $9.6 million, respectively, of depreciation expense, resulting in $14.1 million or 43% decrease in period over period cash spending. Cash general and administrative expenses consist primarily of salaries and related expenses, accounting, legal and administrative expenses, professional service fees and other general corporate expenses.

The significant decrease in general and administrative expenses was primarily the result of several cost saving initiatives that we undertook, including staff reductions of approximately 25% during 2001 that resulted in approximately $4.9 million in annual savings in general and administrative costs and an overall decrease in discretionary spending. We continue to closely monitor our spending as a result of the current market conditions. However, commencing in fiscal 2003, our general and administrative expenses included the general and administrative expenses associated with our Asia-Pacific operations.

Restructuring Charges.    During the year ended December 31, 2002, we recorded restructuring charges of $28.9 million. The restructuring charges consisted of (a) a $5.0 million option fee paid in May 2002 related to the amendment of our approximately 80 acre ground lease in San Jose, California from which we subsequently elected to exercise the option to permanently exclude 40 acres commencing October 1, 2002; (b) a write-off of property and equipment of $2.6 million, primarily leasehold improvements and some equipment, located in two unnecessary U.S. IBX expansion and headquarter office space operating leaseholds we had decided to exit and that do not currently provide any ongoing benefit; (c) a write-off of one U.S. letters of credit totaling $250,000 related to one U.S. operating leasehold we had committed to exit; (d) an accrual of $1.0 million related to the remaining estimated European exit costs; (e) an accrual of $925,000 in severance charges related to a less than 10% reduction in workforce in an effort to reduce the cost structure of our corporate headquarter function that will result in approximately $2.8 million in annual savings; (f) an accrual of $115,000 related to additional U.S. leasehold exit costs and (g) a partial write-off of two letters of credit totaling $19.0 million associated with the exercise in September 2002 of our option to permanently terminate approximately one-half of our lease obligations under the San Jose ground lease.

During the quarter ended September 30, 2001, the Company took a restructuring charge of $48.6 million consisting of $45.3 million related to a revised European services strategy, $2.0 million for certain anticipated excess U.S. leasehold exit costs and $1.3 million related to a reduction in workforce, primarily in selling, general and administrative functions at the Company’s headquarters. During third quarter 2001, the Company decided to partner with another Internet exchange company in Europe rather than build and operate its own centers outside of the U.S. As a result, the Company i) recorded a write-down of its European construction in progress assets to their net realizable value and recorded a charge totaling $29.3 million, ii) accrued certain leasehold exit costs for its European leasehold interests in the amount of $6.4 million, iii) wrote-off its European letters of credit that secured the European leasehold interests in the amount of $8.6 million and iv) accrued various legal, storage and other costs totaling $1.0 million to facilitate this change in strategy. In addition, the Company incurred a $2.0 million restructuring charge for leasehold exit costs associated with certain excess U.S. leases and a $1.3 million restructuring charge related to an approximate 15% reduction in workforce in an effort to streamline and reduce the cost structure of the Company’s headquarter function.

As of December 31, 2002, a total restructuring reserve of $1.7 million remained outstanding for all of the above accrued but unpaid restructuring charges. We began to realize the cost savings benefits resulting from the partial San Jose ground lease termination in cost of revenues during October 2002.

Interest Income.    Interest income decreased to $998,000 from $10.7 million for the year ended December 31, 2002 and 2001, respectively. Interest income decreased due to lower cash, cash equivalent and short-term investment balances held in interest bearing accounts and lower interest rates received on those invested balances.

Interest Expense.    Interest expense decreased to $35.1 million from $43.8 million for the year ended December 31, 2002 and 2001, respectively. The decrease in interest expense was attributable to the retirement of $52.8 million of our 13% senior notes during the first half of 2002 and to the decline in both the principal due and the interest rates associated with our credit facility.

Gain on Debt Extinguishment.    During the first half of 2002, we retired $52.8 million of our senior notes in exchange for approximately 500,000 shares of our common stock and approximately $2.5 million of cash. On

27

Table of Contents

December 31, 2002, we retired an additional $116.8 million of our senior notes in exchange for approximately 1.9 million shares of our common stock and approximately $15.2 million of cash. As a result of these transactions, we recognized a $114.2 million net gain on debt extinguishment during 2002, after deducting transaction costs, interest waived and allocation of unamortized debt issuance costs and debt discount. Although we made payments on our various debt facilities during 2001, we extinguished no senior notes or other debt during the year ended December 31, 2001.

Liquidity and Capital Resources

Since inception, we have financed our operations and capital requirements primarily through the issuance of senior notes, the private sale of preferred stock, our initial and follow-on public stock offerings, our credit facility, our convertible secured notes, our combination with i-STT and Pihana, which brought additional cash into the combined company, and various types of debt facilities and capital lease obligations, for aggregate gross proceeds of $1.0 billion. As of December 31, 2003, our total indebtedness from our non-convertible debt was $68.3 million and our total indebtedness from our convertible debt was $43.6 million as outlined below.

On February 11, 2004, we sold $75.0 million in aggregate principal of 2.5% convertible subordinated debentures due 2024 to qualified institutional buyers. Subsequently, on February 18, 2004, we sold an additional $11.25 million of our debentures to the initial purchasers of these debentures. We used or intend to use the net proceeds from this offering to repay all amounts outstanding under our credit facility and two of our other debt facilities. In addition, we intend to use the proceeds received to redeem our 13% senior notes. We have exercised our right to redeem all of its 13% senior notes, which have a total of $30.5 million of principal outstanding and have sent a notice of redemption to the trustee. The effective date of the redemption is expected to be March 12, 2004. The redemption price for the senior notes will be equal to 106.5% of their principal amount plus accrued and unpaid interest to the redemption date. Lastly, all remaining proceeds will be used for general corporate purposes. We expect to record a significant loss on debt extinguishment during the quarter ended March 31, 2004, primarily related to the non-cash write-off of debt issuance costs and discounts in connection with these various debt repayments and redemptions, as well as the cash premium we will pay on our 13% senior notes. We refer to this transaction as the “convertible debenture offering”.

As of December 31, 2003, our principal source of liquidity was our $73.0 million of cash, cash equivalents and short-term investments. We believe that this cash, coupled with the proceeds from the convertible debenture offering and our anticipated cash flows generated from operations, will be sufficient to meet our capital expenditure, working capital, debt service, including repayments and redemptions of our non-convertible debt as planned, and corporate overhead requirements for at least the next 12 months.

While we had generated negative operating cashflow in each annual period since inception, commencing the quarter ended September 30, 2003 we started to generate positive operating cash flow. During this quarter, our recurring revenues grew to a level sufficient to meet our operating cash requirements related to our predominantly fixed cost structure. We considered this quarter to be the inflection point in our business model whereby our revenues were sufficient on an ongoing basis to meet all our operating costs and working capital requirements. As a result of reaching this point in our operating history, we expect to generate cash from our operations during 2004 and expect these operating cash flows to be sufficient to meet our cash requirements to fund our capital expenditures. Given our limited operating history, we may not achieve our desired levels of profitability. See “Risk Factors.”

Uses of Cash

Net cash used in our operating activities was $17.3 million, $27.5 million and $68.9 million for the years ended December 31, 2003, 2002 and 2001, respectively. We used cash during these periods primarily to fund our net loss, including cash interest payments on our senior notes and credit facility, although the majority of the operating cash flows used in 2003 related to the liquidation of accrued obligations at December 31, 2002

Table of Contents

attributed to the combination and financing transactions and restructuring activities. Our net cash used in operations has decreased each year as our revenues have grown. As described above, we expect that we will generate cash from our operating activities in 2004.

Net cash used in investing activities was $15.6 million, $7.5 million and $153.0 million for the years ended December 31, 2003, 2002 and 2001, respectively. Net cash used in investing activities in during the year ended December 31, 2003 was primarily to fund capital expenditures to support our growing customer base and the purchase of short-term investments. Net cash used in investing activities during the year ended December 31, 2002 was primarily attributable to the liquidation of accrued construction costs for the New York metropolitan area IBX hub, which opened during the first quarter of 2002, partially offset by the sale of short-term investments. Net cash used in investing activities during the year ended December 31, 2001 was primarily attributable to the construction of our IBX hubs and the purchase of restricted cash and short-term investments. The amount of cash used in investing activities has decreased substantially since 2001 as we have substantially completed our current IBX hub rollout plan. For 2004, we anticipate that our cash used in investing activities, excluding the purchase and sale of short-term investments, will be attributed to the funding of our capital expenditures.

Net cash generated by financing activities was $52.3 million, $16.9 million and $107.8 million for the years ended December 31, 2003, 2002 and 2001, respectively. Net cash generated by financing activities during the year ended December 31, 2003 was primarily the result of the $104.4 million in proceeds from our follow-on equity offering and $10.0 million in proceeds from the Crosslink financing, partially offset by $57.2 million in payments on our credit facility and $6.1 million in payments on our various other debt facilities and capital lease obligations. Net cash generated by financing activities during the year ended December 31, 2002 was primarily attributable to the cash acquired in the acquisitions of i-STT and Pihana and proceeds from our $30.0 million convertible secured notes, offset by payments of $17.7 million used to retire approximately $169.5 million of our senior notes and the costs associated with the exchange of the senior notes and repayments under our credit facility of $13.5 million. Net cash generated by financing activities during the year ended December 31, 2001 was primarily attributable to the net $105.0 million draw down under our credit facility.

Debt Obligations—Non-Convertible Debt

As of December 31, 2003, our total indebtedness from non-convertible debt was $68.3 million, comprised of our senior notes, credit facility, and other debt facilities and capital lease obligations as follows:

Senior Notes.    In December 1999, we issued $200.0 million aggregate principal amount of 13% senior notes due 2007. During 2002, we retired $169.5 million of the senior notes in exchange for approximately 2.4 million shares of common stock and approximately $21.3 million of cash. As of December 31, 2003, a total of $30.5 million of senior note principal remained outstanding, which is presented, net of unamortized discount, on our balance sheet at $29.2 million. In February 2004, with the net proceeds from our convertible debenture offering, we have exercised our right to redeem all of our senior notes. A notice has been sent to the trustee and the effective date of the redemption of our senior notes is expected to be March 12, 2004. The redemption price for the senior notes will be equal to 106.5% of their principal amount plus accrued and unpaid interest to the redemption date.

Credit Facility.    In December 2000, we entered into the credit facility with a syndicate of lenders under which, subject to our compliance with a number of financial ratios and covenants, we were permitted to borrow up to $150.0 million, which was fully drawn down during 2001. This facility was amended at various times during 2001 and 2002. In connection with the follow-on equity offering in November 2003, we entered into a further amendment to the credit facility and permanently repaid $55.2 million of the then outstanding principal balance of $90.5 million. As of December 31, 2003, a total of $34.3 million of principal remained outstanding under the credit facility. In February 2004, with the net proceeds from our convertible debenture offering, we repaid all amounts outstanding under our credit facility and terminated the credit facility.

Other Debt Facilities and Capital Lease Obligations.    In August 1999, we entered into a loan agreement with Venture Lending and Leasing in the amount of $10.0 million and fully drew down on this amount. This loan agreement bears interest at 8.5% and was repayable over 42 months in equal monthly payments with a final interest payment equal to 15% of the advance amounts due on maturity. In October 2002, we amended the loan agreement to secure certain short-term cash deferment benefits. Under the terms of this amendment, we extended the maturity of the loan by 24 months and amortized the remaining principal balance and related balloon interest payment over this amended period ending March 1, 2005. In exchange, the Company issued new warrants and re-priced the original warrants. As of December 31, 2003, principal of $847,000 remained outstanding. In March 2004, with the net proceeds from our convertible debenture offering, we will pay off this other debt facility in full.

In June 2001, we entered into a loan agreement with Heller Financial Leasing in the amount of $5.0 million and fully drew down on this amount. This loan agreement bears interest at 13.0% and is repayable over 36 months. In August 2002, we amended this loan to secure certain short-term cash deferments. Under the amended terms of this loan agreement, we extended the maturity of the loan by nine months. Commencing September 2002, we began to benefit from the reduction in monthly payments over the following 14 months thereby deferring approximately $1.2 million of principal payments. Commencing November 2003, the deferred principal payments will be repaid over the remaining 17 months of the loan ending March 2005. As of December 31, 2003, principal of $2.5 million remained outstanding. In February 2004, with the net proceeds from our convertible debenture offering, we paid off this other debt facility in full.

In December 2002, in conjunction with our merger with Pihana, we acquired multiple capital leases with Orix. The original amount financed was approximately $3.5 million. These capital lease arrangements bear interest at an average rate of 6.4% per annum and are repayable over 30 months. As of December 31, 2003, principal of $201,000 remained outstanding. These capital leases will be fully paid down by March 31, 2004.

As of December 31, 2003, a total of $3.5 million of our other debt facilities and capital lease obligations were outstanding, which is presented, net of unamortized discount, on our balance sheet at $3.4 million.

Debt Obligations—Convertible Debt

Convertible Secured Notes.    In December 2002, in conjunction with the combination, STT Communications made a $30.0 million strategic investment in the company in the form of a 14% convertible secured note due November 2007. The interest on the convertible secured note is payable in kind in the form of additional convertible secured notes, which we refer to as “PIK notes”. During 2003, we issued $3.6 million in PIK notes. The convertible secured note and PIK notes issued to STT Communications are convertible into our preferred and common stock at a price of $9.18 per underlying share, which represents 3.7 million shares as of December 31, 2003, and are convertible anytime at the option of STT Communications. After December 31, 2004 and through December 31, 2005, we may convert 95% of the STT Communications’ convertible secured notes and after December 31, 2005, we may convert 100% of these convertible secured notes upon certain conditions, including if the closing price of our common stock exceeds $32.12 per share for thirty consecutive trading days.

In June 2003, entities affiliated with Crosslink Capital made a $10.0 million strategic investment in the company in the form of 10% convertible secured notes due November 2007. The interest on the convertible secured notes is payable in kind in the form of additional convertible secured notes commencing on the second anniversary of the closing of this transaction. As of December 31, 2003, the convertible secured notes issued to the entities affiliated with Crosslink were convertible into 2.5 million shares of our common stock, and are convertible anytime at the option of Crosslink Capital. Following the second anniversary of the closing of the Crosslink financing, 100% of the Crosslink convertible secured notes will automatically convert upon certain conditions, including if the closing price of our common stock exceeds $15.66 per share for thirty consecutive trading days. We recorded a substantial debt discount equal to the $10.0 million of principal in connection with the Crosslink financing, primarily as a result of the beneficial conversion feature associated with these convertible secured notes, which is being amortized to interest expense over the term of the Crosslink financing.

30

Table of Contents

As of December 31, 2003, a total of $43.6 million of convertible secured notes were outstanding, which is presented, net of unamortized discount, on our balance sheet at $31.7 million. All interest expense associated with our convertible secured notes, including the amortization of the unamortized discount of $11.9 million, represents non-cash interest expense in our statements of operation and cash flow as no cash is expended for this interest.

Convertible Subordinated Debentures.    On February 11, 2004, we sold $75.0 million in aggregate principal of 2.5% convertible subordinated debentures due 2024 to qualified institutional buyers. Subsequently, on February 18, 2004, we sold an additional $11.25 million of our debentures to the initial purchasers of these debentures. We used the net proceeds from this offering to repay all amounts outstanding under our credit facility and two of our other debt facilities. In addition, we intend to use additional proceeds received to redeem our 13% senior notes. We have exercised our right to redeem all of its 13% senior notes, which have a total of $30.5 million of principal outstanding and have sent a notice of redemption to the trustee. The effective date of the redemption is expected to be March 12, 2004. Lastly, all remaining proceeds will be used for general corporate purposes The interest on the convertible subordinated debentures is payable semi-annually every February and August commencing August 2004. Unlike our convertible secured notes, the interest on our convertible subordinated debentures will be payable in cash. Our convertible subordinated debentures will be convertible into 2.2 million shares of our common stock.

Holders of the convertible subordinated debentures may require us to purchase all or a portion of their debentures on February 15, 2009, February 15, 2014 and February 15, 2019, in each case at a price equal to 100% of the principal amount of the debentures plus any accrued and unpaid interest. In addition, holders of the convertible subordinated debentures may convert their debentures into shares of our common stock upon certain defined circumstances, including during any calendar quarter after the quarter ending June 30, 2004 if the closing price of our common stock exceeds $47.40 per share for twenty consecutive trading days. We may redeem all or a portion of the debentures at any time after February 15, 2009 at a redemption price equal to 100% of the principal amount of the debentures plus any accrued and unpaid interest.

Debt Maturities and Operating Lease Commitments

We lease our IBX hubs and certain equipment under non-cancelable operating lease agreements expiring through 2020. The following represents the minimum future operating lease payments for these commitments, as well as the combined aggregate maturities for all of our debt as of December 31, 2003 (in thousands):

Table of Contents

If the Company had completed the convertible subordinated debenture offering during 2003 instead of February 2004, and had used the proceeds from this offering to repay all amounts outstanding under our credit facility and two of our other debt facilities, as well as redeemed all remaining senior notes, as intended, the obligations presented above would have been as follows on a pro forma basis as of December 31, 2003 (in thousands):

As of December 31, 2003, we had capital expenditure commitments of approximately $1.0 million related to a small expansion of our Singapore IBX hub, which we expect to fund during the first half of 2004. In addition, we expect to spend approximately $3.0 to $5.0 million to bring our recently-acquired Santa Clara IBX hub to Equinix standards during the first half of 2004.

With respect to the operating lease for one of our New York metropolitan area IBXs, our landlord has the right to increase our rentable space on December 31, 2004 when the lease for the current tenant’s portion of the aggregate property lease expires. As a result, commencing fiscal 2005, our total rent expense associated with this IBX hub could double. This increase in our operating lease commitments is reflected in the tables presented above. We are currently working with this landlord, as well as the current tenant of that space, and expect to minimize this additional cost to us; however, there can be no assurances that we will be successful in reducing this commitment.

Strategically, we will continue to look at attractive opportunities to grow our market share and selectively improve our footprint and service streams, such as our recent acquisition of the Sprint property in Santa Clara. However, we will continue to be very selective with any similar opportunity. As was the case with the Sprint property, the criteria will be quality of the design, access to networks, capacity availability in current market location, amount of incremental investment in the targeted property, lead-time to breakeven and in-place customers. Like the Sprint property, the right combination of these factors may be quite attractive for us. Dependent on the particular deal, these acquisitions may require additional capital expenditures in order to bring these centers up to Equinix standards.

RISK FACTORS

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

Risks Related to Our Business

We have a limited operating history and we face challenges typically experienced by early-stage companies.

We were founded in June 1998 and did not recognize any revenue until November 1999. In October 2002, we entered into agreements to consummate a series of related acquisition and financing transactions. These transactions closed on December 31, 2002. Under the terms of these agreements, we combined our business with two similar businesses, that of i-STT Pte Ltd, or i-STT, and Pihana Pacific, Inc., or Pihana. We refer to this transaction as the combination. i-STT was founded in January 2000 and did not recognize any revenue until May 2000. Pihana was founded in June 1999 and did not recognize any revenue until June 2000. We expect that we will encounter challenges and difficulties frequently experienced by early-stage companies in new and rapidly evolving international markets, such as our ability to generate cash flow, hire, train and retain sufficient operational and technical talent, and implement our plan with minimal delays. We may not successfully address any or all of these challenges and our failure to do so would seriously harm our business plan and operating results, and affect our ability to raise additional funds.

Equinix’s, i-STT’s and Pihana’s businesses have incurred substantial losses in the past, may continue to incur additional losses in the future and will not be profitable until the combined company reverses this trend.

For the year ended December 31, 2003, the combined company incurred losses of $84.2 million. Until the quarter ended September 30, 2003, the combined company did not generate cash from operations. There can be no guarantee that the combined company will become profitable and the combined company may continue to incur additional losses. Even if the combined company achieves profitability, given the competitive and evolving nature of the industry in which it operates, the combined company may not be able to sustain or increase profitability on a quarterly or annual basis.

We expect our operating results to fluctuate.

Equinix has experienced fluctuations in its results of operations on a quarterly and annual basis. The fluctuation in our operating results may cause the market price of our common stock to decline. We expect to experience significant fluctuations in our operating results in the foreseeable future due to a variety of factors, including:

33

Table of Contents

Any of the foregoing factors, or other factors discussed elsewhere in this offering memorandum, could have a material adverse effect on our business, results of operations, and financial condition. Although the combined company has experienced growth in revenues in recent quarters, this growth rate is not necessarily indicative of future operating results. It is possible that the combined company may never generate net income on a quarterly or annual basis. 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 the combined company’s future performance. In addition, our operating results in one or more future quarters may fail to meet the expectations of securities analysts or investors. If this occurs, we could experience an immediate and significant decline in the trading price of our stock.

Our inability to use our tax net operating losses will cause us to pay taxes at an earlier date and in greater amounts which may harm our operating results.

We believe that our ability to use our tax net operating losses, or NOLs, in any taxable year is subject to limitation under Section 382 of the Code as a result of the significant change in the ownership of our stock that resulted from the combination. We expect that almost all of our NOLs accrued prior to December 31, 2002 will expire unused as a result of this limitation. In addition to the limitations on NOL carryforward utilization described above, we believe that Section 382 of the Code will also significantly limit our ability to use the depreciation and amortization on our assets, as well as certain losses on the sale of our assets, to the extent that such depreciation, amortization and losses reflect unrealized depreciation that was inherent in such assets as of the date of the combination. These limitations will cause us to pay taxes at an earlier date and in greater amounts than would occur absent such limitations.

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

In 2002, our sales outside North America represented less than 1% of our revenues, i-STT’s sales outside North America represented approximately 100% of its revenues and Pihana’s sales outside North America represented approximately 45% of its revenues. For the year ended December 31, 2003, the combined company recognized 15% of its revenues outside North America. We anticipate that, for the foreseeable future, approximately 15% of the combined company’s revenues will be derived from sources outside North America. Our management team is comprised primarily of Equinix executives before the combination, some of whom have had limited or no experience overseeing international operations.

To date, the neutrality of the Equinix IBX hubs and the variety of networks available to our customers has often been a competitive advantage for us. In certain of our recently acquired IBX hubs, in Singapore in particular, the limited number of carriers available diminishes that advantage. As a result, we may need to adapt our key revenue-generating services and pricing to be competitive in that market.

We may experience gains and losses resulting from fluctuations in foreign currency exchange rates. To date, the majority of Equinix’s revenues and costs have been denominated in U.S. dollars, the majority of i-STT’s revenues and costs have been denominated in Singapore dollars and the majority of Pihana’s revenues and costs have been denominated in U.S. dollars, Japanese yen and Australian, Hong Kong and Singapore dollars. Although

34

Table of Contents

the combined company may undertake foreign exchange hedging transactions to reduce foreign currency transaction exposure, it does not currently intend to eliminate all foreign currency transaction exposure. Where our prices are denominated in U.S. dollars, our sales could be adversely affected by declines in foreign currencies relative to the U.S. dollar, thereby making our products more expensive in local currencies. Our international operations are generally subject to a number of additional risks, including:

We may make acquisitions, which pose integration and other risks, that could harm our business.

We may seek to acquire additional IBX centers, complementary businesses, products, services and technologies. As a result of these acquisitions, we may be required to incur additional debt and expenditures and issue additional shares of our stock to pay for the acquired business, product, service or technology, which will dilute existing stockholders’ ownership interest in the combined company and may delay, or prevent, our profitability. These acquisitions may also expose us to risks such as:

On October 27, 2003, we announced that we signed an agreement to sublease Sprint’s E|Solutions Internet Center in Santa Clara and acquire certain related assets. Such sublease went into effect on December 1, 2003. In negotiating this transaction we were only able to conduct limited due diligence and received limited representations and warranties. If the subleased facility and acquired assets are not in the condition we believe them to be in, we may be required to incur substantial additional costs to repair the acquired facility and related assets. If incurred, these costs could materially adversely affect our business, financial condition and results of operations.

We cannot assure you that we would successfully overcome these risks or any other problems encountered with these acquisitions.

STT Communications holds a substantial portion of our stock and has significant influence over matters requiring stockholder consent.

As of December 31, 2003, STT Communications owned approximately 28.5% of our outstanding voting stock. In addition, STT Communications is not prohibited from buying shares of our stock in public or private transactions. Because of the diffuse ownership of our stock, STT Communications has significant influence over matters requiring our stockholder approval. Following the expiration on December 31, 2004 of restrictions on STT Communications preventing it from converting its convertible secured notes and warrants into more than 40% of our voting stock, STT Communications may own more than 40% of our voting stock. As a result, STT

35

Table of Contents

Communications will be able to exercise significant control over all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions, which could prevent or delay a third party from acquiring or merging with us. STT also has a right of first offer which entitles them to participate in an offering of our equity securities, or securities convertible into our equity securities, to maintain their ownership percentage prior to such offering.

We may be forced to take steps, and may be prevented from pursuing certain business opportunities, to ensure compliance with certain tax-related covenants agreed to by us in the combination agreement.

We agreed to a covenant in the combination agreement (which we refer to as the FIRPTA covenant) that we would use all commercially reasonable efforts to ensure that at all times from and after the closing of the combination until such time as neither STT Communications nor its affiliates hold our capital stock or debt securities (or the capital stock received upon conversion of the debt securities) received by STT Communications in connection with the consummation of the transactions contemplated in the combination agreement, none of our capital stock issued to STT Communications would constitute “United States real property interests” within the meaning of Section 897(c) of the Code. Under Section 897(c) of the Code, our capital stock issued to STT Communications would generally constitute “United States real property interests” at such point in time that the fair market value of the “United States real property interests” owned by us equals or exceeds 50% of the sum of the aggregate fair market values of (a) our “United States real property interests,” (b) our interests in real property located outside the U.S., and (c) any other assets held by us which are used or held for use in our trade or business. Given that we currently own significant amounts of “United States real property interests,” we may be limited with respect to the business opportunities we may pursue, particularly if the business opportunities would increase the amounts of “United States real property interests” owned by us or decrease the amount of other assets owned by us. In addition, pursuant to the FIRPTA covenant we may be forced to take commercially reasonable proactive steps to ensure our compliance with the FIRPTA covenant, including, but not limited to, (a) a sale-leaseback transaction with respect to all real property interests, or (b) the formation of a holding company organized under the laws of the Republic of Singapore which would issue shares of its capital stock in exchange for all of our outstanding stock (this reorganization would require the submission of that transaction to our stockholders for their approval and the consummation of that exchange). We will only be required to take these actions if such actions are commercially reasonable for Equinix or our stockholders.

Our non-U.S. customers include numerous related parties of i-STT.

In the past, a substantial portion of i-STT’s financing, as well as its revenues, has been derived from its affiliates, including STT Communications. We continue to have contractual and other business relationships and may engage in material transactions with affiliates of STT Communications. Circumstances may arise in which the interests of STT Communications’ affiliates may conflict with the interests of our other stockholders. In addition, Singapore Technologies Pte Ltd, the parent company of STT Communications, makes investments in various companies; it has invested in the past, and may invest in the future, in entities that compete with us. In the context of negotiating commercial arrangements with affiliates, conflicts of interest have arisen in the past and may arise, in this or other contexts, in the future. We cannot assure you that any conflicts of interest will be resolved in our favor.

A significant number of shares of our capital stock have been issued during 2002 and 2003 and may be sold in the market in the near future. This could cause the market price of our common stock to drop significantly, even if our business is doing well.

We issued a large number of shares of our capital stock to the former Pihana stockholders, STT Communications, and holders of our senior notes in connection with the combination, financing and senior note exchange, to Crosslink Capital in connection with the Crosslink financing and to the public and STT Communications in connection with our recent follow-on equity offering. The shares of common stock issued in the senior note exchange are currently freely tradeable. The shares of common stock issued in connection with

36

Table of Contents

the combination have been registered for resale as of June 30, 2003 and the shares of common stock issued upon exercise of the warrants issued in connection with the Crosslink financing have been registered for resale as of September 22, 2003. The shares sold to the public and STT Communications in connection with our recent follow-on equity offering are freely tradeable by the public, subject, in the case of STT Communications, to compliance with Rule 144 resale restrictions applicable to affiliates. Subject to the restrictions described in our proxy statement dated December 12, 2002, the convertible secured notes and warrants issued in connection with the financing and the Crosslink financing are immediately convertible or exercisable into shares of common stock and the underlying shares of common stock may be registered for resale. Sales of a substantial number of shares of our common stock by these parties within any narrow period of time could cause our stock price to fall. In addition, the issuance of the additional shares of our common stock as a result of these transactions will reduce our earnings per share, if any. This dilution could reduce the market price of our common stock unless and until we achieve revenue growth or cost savings and other business economies sufficient to offset the effect of this issuance. We cannot assure you that we will achieve revenue growth, cost savings or other business economies.

A significant number of our shares may be sold into the public market if STT Communications defaults on its credit facility which could cause the market price of our common stock to drop significantly.

STT Communications currently holds our common stock or holds securities convertible into shares of our common stock totaling 8,565,520 shares. STT Communications has pledged to its lenders its ownership interest in the majority of its secured notes and warrants purchased in the financing and its common and preferred stock issued in the combination as collateral for its secured credit facility. If STT Communications defaults on its credit facility, the stock, warrants and secured notes owned by STT Communications could be transferred to its lenders or sold to third parties. In the event of default, the new owner of the secured notes and warrants could convert them into our common stock and sell them, along with the common stock, into the public market. Sales of a substantial number of shares of our common stock by these parties within any narrow period of time could cause our stock price to fall. In addition, the issuance of the additional shares of our common stock as a result of these transactions will reduce our earnings per share, if any.

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

The presence of diverse telecommunications carriers’ fiber networks in our IBX hubs is critical to our ability to attract new customers. We believe that the availability of carrier capacity will directly affect our ability to achieve our projected results.

We are not a telecommunications carrier, and as such we rely on third parties to provide our customers with carrier services. We rely primarily on revenue opportunities from the telecommunications carriers’ customers to encourage them to invest the capital and operating resources required to build facilities from their locations to our IBX hubs. Carriers will likely evaluate the revenue opportunity of an IBX hub based on the assumption that the environment will be highly competitive. We cannot assure you that any carrier will elect to offer its services within our IBX hubs or that once a carrier has decided to provide Internet connectivity to our IBX hubs that it will continue to do so for any period of time.

The construction required to connect multiple carrier facilities to our IBX hubs is complex and involves factors outside of our control, including regulatory processes and the availability of construction resources. If the establishment of highly diverse Internet connectivity to our IBX hubs does not occur or is materially delayed or is discontinued, our operating results and cash flow will be adversely affected. Further, many carriers are experiencing business difficulties. As a result, some carriers may be forced to terminate connectivity within our IBX hubs.

Any failure of our physical infrastructure or services 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 service. We must protect customers’ IBX infrastructure and customers’ equipment located in our IBX hubs. The services we provide are subject to failure resulting from numerous factors, including:

Problems at one or more of our IBX hubs, 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 hubs could result in service level commitments to these customers. In the past, a limited number of our customers have experienced temporary losses of power and failure of our services levels on products such as bandwidth connectivity. If we incur significant financial commitments to our customers in connection with a loss of power, or our failure to meet other service level commitment obligations, our liability insurance may not be adequate to cover those expenses. In addition, any loss of services, equipment damage or inability to meet our service level commitment obligations, particularly in the early stage of our development, 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 U.S., Asia and elsewhere, some of which may have experienced significant system failures and electrical outages in the past. Users of our services may in the future experience difficulties due to system failures unrelated to our systems and services. If for any reason, these providers fail to provide the required services, our business, financial condition and results of operations could be materially adversely impacted.

A portion of the managed services business we acquired in the combination involves the processing and storage of confidential customer information. Inappropriate use of those services could jeopardize the security of customers’ confidential information causing losses of data or financially impacting us or our customers. Efforts to alleviate problems caused by computer viruses or other inappropriate uses or security breaches may lead to interruptions, delays or cessation of our managed services.

There is no known prevention or defense against denial of service attacks. During a prolonged denial of service attack, Internet service will not be available for several hours, thus impacting hosted customers’ on-line business transactions. Affected customers might file claims against us under such circumstances.

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

Our IBX hubs are susceptible to regional costs of power, electrical power shortages, planned or unplanned power outages caused by these shortages such as those that occurred in California during 2001 and in the Northeast in 2003, and limitations, especially internationally, of adequate power resources. The overall power shortage in California has increased the cost of energy, which we may not be able to pass on to our customers.

38

Table of Contents

We attempt to limit exposure to system downtime by using backup generators and power supplies. Power outages, which last beyond our backup and alternative power arrangements, could harm our customers and our business.

We resell products and services of third parties that may require us to pay for such services even if our customers fail to pay us for the services which may have a negative impact on our operating results.

In order to provide resale services such as bandwidth, managed services, backup and recovery services and other network management services, we will contract with third party service providers. These services require us to enter into fixed term contracts for services with third party suppliers of products and services. If we experience the loss of a customer who has purchased a resale product, we will remain obligated to continue to pay our suppliers for the term of the underlying contracts. The payment of these obligations without a corresponding payment from customers will reduce our financial resources and may have a material adverse affect on our financial performance and operating results.

IBM accounts for a significant portion of our revenues, and the loss of IBM as a customer could significantly harm our business, financial condition and results of operations.

For the year ended December 31, 2003, IBM accounted for 15% of our revenue and as of December 31, 2003 accounted for 11% of our accounts receivable. For the year ended December 31, 2002, IBM accounted for 20% of our revenue and as of December 31, 2002 accounted for 15% of our accounts receivable. We expect that IBM will continue to account for a significant portion of our revenue for the foreseeable future, although we expect revenues received from IBM to decline as a percentage of our total revenues as we add new customers in our IBX hubs. If we lose IBM as a customer, our business, financial condition and results of operations could be adversely affected.

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

Our IBX hubs and other products and services must be able to differentiate themselves from existing providers of space and services for telecommunications companies, web hosting companies and other colocation providers. In addition to competing with neutral colocation providers, we must compete with traditional colocation providers, including local phone companies, long distance phone companies, Internet service providers and web hosting facilities. Likewise, with respect to our other products and services, including managed services, bandwidth services and security services, we must compete with more established providers of similar services. Most of these companies have longer operating histories and significantly greater financial, technical, marketing and other resources than us.

Because of their greater financial resources, some of our competitors have the ability to adopt aggressive pricing policies, especially if they have been able to restructure their debt or other obligations. As a result, in the future, we may suffer from pricing pressure that would adversely affect our ability to generate revenues and adversely affect our operating results. In addition, these competitors could offer colocation on neutral terms, and may start doing so in the same metropolitan areas where we have IBX hubs. Some of these competitors may also provide our target customers with additional benefits, including bundled communication services, and may do so in a manner that is more attractive to our potential customers than obtaining space in our IBX hubs. We believe our neutrality provides us with an advantage over these competitors. However, if these competitors were able to adopt aggressive pricing policies together with offering colocation space, our ability to generate revenues would be materially adversely affected.

We may also face competition from persons seeking to replicate our IBX concept by building new centers or converting existing centers that some of our competitors are in the process of divesting. Competitors may operate more successfully or form alliances to acquire significant market share. Furthermore, enterprises that have already invested substantial resources in peering arrangements may be reluctant or slow to adopt our approach that may replace, limit or compete with their existing systems. In addition, other companies may be able to attract

the same potential customers that we are targeting. Once customers are located in competitors’ facilities, it will be extremely difficult to convince them to relocate to our IBX hubs.

Because we depend on the development and growth of a balanced customer base, failure to attract 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 network service providers, site and performance management companies, and enterprise and content companies. The more balanced the customer base within each IBX hub, 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 hubs will depend on a variety of factors, including the presence of multiple carriers, the mix of products and services offered by us, the overall mix of customers, the IBX hub’s operating reliability and security and our ability to effectively market our services. In addition, some of our customers are and will continue to be Internet companies that face many competitive pressures and that may not ultimately be successful. If these customers do not succeed, they will not continue to use the IBX hubs. This may be disruptive to our business and may adversely affect our business, financial condition and results of operations.

Increases in property taxes could adversely affect our business, financial condition and results of operations.

Our IBX hubs are subject to state and local real property taxes. The state and local real property taxes on our IBX hubs may increase as property tax rates change and as the value of the properties are assessed or reassessed by taxing authorities. Many state and local governments are facing budget deficits, which may cause them to increase assessments or taxes. If property taxes increase, our business, financial condition and operating results could be adversely affected.

Our products and services have a long sales cycle that may materially adversely affect our business, financial condition and results of operations.

A customer’s decision to license cabinet space in one of our IBX hubs and to purchase additional services typically involves a significant commitment of resources and will be influenced by, among other things, the customer’s confidence in our financial strength. In addition, some customers will be reluctant to commit to locating in our IBX hubs until they are confident that the IBX hub has adequate carrier connections. As a result, we have a long sales cycle. Delays due to the length our sales cycle may materially adversely affect our business, financial condition and results of operations.

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

In the past, securities class action litigation has often been brought against a company following periods of volatility in the market price of its securities. During the quarter ended September 30, 2001, putative shareholder class action lawsuits were filed against us, a number of our officers and directors, and several investment banks that were underwriters of our initial public offering. The suits allege that the underwriter defendants agreed to allocate stock in our initial public offering to certain investors in exchange for excessive and undisclosed commissions and agreements by those investors to make additional purchases in the aftermarket at pre-determined prices. Plaintiffs allege that the prospectus for our initial public offering was false and misleading and in violation of the securities laws because it did not disclose these arrangements. In July 2003, a special litigation committee of our board of directors agreed to participate in a settlement with the plaintiffs. The settlement agreement is subject to court approval and sufficient participation by defendants in similar actions. If the proposed settlement is not approved by the court or a sufficient number of defendants do not participate in the settlement, the defense of this litigation may increase our expenses and divert management’s attention and resources. An adverse outcome in this litigation could seriously harm our business and results of operations. In addition, we may, in the future, be subject to other securities class action or similar litigation.

Risks Related to Our Industry

If the economy does not improve and the use of the Internet and electronic business does not grow, our revenues may not grow.

Acceptance and use of the Internet may not continue to develop at historical rates and a sufficiently broad base of consumers may not adopt or continue to use the Internet and other online services as a medium of commerce. Demand for Internet services and products are subject to a high level of uncertainty and are subject to significant pricing pressure, especially in Asia-Pacific. As a result, we cannot be certain that a viable market for our IBX hubs will materialize. If the market for our IBX hubs grows more slowly than we currently anticipate, our revenues will not grow as expected and our operating results will suffer.

Government regulation may adversely affect the use of the Internet and our business.

Various laws and governmental regulations governing Internet related services, related communications services and information technologies, and electronic commerce remain largely unsettled, even in areas where there has been some legislative action. This is true both in the U.S. and the various foreign countries in which we now operate. It 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 services such as ours. We have limited experience with such international regulatory issues 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 compliance with, adoption or modification of, laws or regulations relating to the Internet, or interpretations of existing laws, could have a material adverse effect on our business, financial condition and results of operation.

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

The September 11, 2001 terrorist attacks in the U.S., the ensuing declaration of war on terrorism and the continued threat of terrorist activity and other acts of war or hostility appear to be having an adverse effect on business, financial and general economic conditions internationally. These effects may, in turn, increase our costs due to the need to provide enhanced security, 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 hubs.

Recent Accounting Pronouncements

In November 2002, the Emerging Issues Task Force reached a consensus on Issue No. 00-21, “Revenue Arrangements with Multiple Deliverables,” or EITF 00-21. EITF 00-21 provides guidance on how to account for arrangements that involve the delivery or performance of multiple products, services and/or rights to use assets. The provisions of EITF 00-21 apply to revenue arrangements entered into in fiscal periods beginning after June 15, 2003. We adopted the provisions of EITF 00-21 during the third quarter of 2003. The adoption of this statement has not had a material impact on our results of operations, financial position or cash flows.

In January 2003, the FASB issued FASB Interpretation No. 46, or FIN 46, “Consolidation of Variable Interest Entities, an Interpretation of ARB No. 51.” FIN 46 requires certain variable interest entities to be consolidated by the primary beneficiary of the entity if the equity investors in the entity do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. FIN 46 is effective immediately for all new variable interest entities created or acquired after January 31, 2003. In December 2003, the FASB

41

Table of Contents

released a revised version of FIN 46 clarifying certain aspects of FIN 46 and providing certain entities with exemptions from the requirements of FIN 46. For variable interest entities created or acquired prior to February 1, 2003, the provisions of FIN 46 must be applied for the first interim or annual period ending after March 15, 2004. The adoption of Fin 46 did not have a material impact on our results of operations, financial position or cash flows.

In April 2003, the FASB issued SFAS No. 149, “Amendment of Statement 133 on Derivative Instruments and Hedging Activities.” SFAS No. 149 amends and clarifies accounting for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities under SFAS No. 133. The new guidance amends SFAS No. 133 for decisions made as part of the Derivatives Implementation Group, or DIG, process that effectively required amendments to SFAS No. 133, and decisions made in connection with other FASB projects dealing with financial instruments and in connection with implementation issues raised in relation to the application of the definition of a derivative and characteristics of a derivative that contains financing components. In addition, it clarifies when a derivative contains a financing component that warrants special reporting in the statement of cash flows. SFAS No. 149 is effective for contracts entered into or modified after June 30, 2003 and for hedging relationships designated after June 30, 2003. We adopted the provisions of SFAS No. 149 during the third quarter of 2003. The adoption of this statement has not had a material impact on our results of operations, financial position or cash flows.

In May 2003, the FASB issued SFAS No. 150, “Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity.” SFAS No. 150 establishes standards for how an issuer classifies and measures in its statement of financial position certain financial instruments with characteristics of both liabilities and equity. It requires that an issuer classify a financial instrument that is within its scope as a liability (or an asset in some circumstances) because that financial instrument embodies an obligation of the issuer. In November 2003, the FASB issued FASB Staff Position No. FASB 150-3 which deferred the measurement provisions of SFAS No. 150 indefinitely for certain mandatorily redeemable non-controlling interests that were issued before November 5, 2003. The FASB plans to reconsider implementation issues and, perhaps, classification or measurement guidance for those non-controlling interests during the deferral period. In 2003, we applied certain disclosure requirements of SFAS No. 150. To date, the impact of the effective provisions of SFAS No. 150 have not had a material impact on our results of operations, financial position or cash flows. While the effective date of certain elements of SFAS No. 150 have been deferred, the adoption of SFAS No. 150 when finalized is not expected to have a material impact on our financial position, results of operations or cash flows.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk

The following discussion about market risk disclosures involves forward-looking statements. Actual results could differ materially from those projected in the forward-looking statements. We may be exposed to market risks related to changes in interest rates and foreign currency exchange rates and to a lesser extent we are exposed to fluctuations in the prices of certain commodities, primarily electricity.

In the past, we have employed foreign currency forward exchange contracts for the purpose of hedging certain specifically identified net currency exposures. The use of these financial instruments was intended to mitigate some of the risks associated with fluctuations in currency exchange rates, but does not eliminate such risks. We may decide to employ such contracts again in the future. We do not use financial instruments for trading or speculative purposes.

Interest Rate Risk

Our exposure to market risk resulting from changes in interest rates relates primarily to our investment portfolio. Our interest income is impacted by changes in the general level of U.S. interest rates, particularly since

42

Table of Contents

the majority of our investments are in short-term instruments. Due to the short-term nature of our investments, we do not believe that we are subject to any material market risk exposure. An immediate 10% increase or decrease in current interest rates would not have a material effect on the fair market value of our investment portfolio. We would not expect our operating results or cash flows to be significantly affected by a sudden change in market interest rates in our investment portfolio.

An immediate 10% increase or decrease in current interest rates would furthermore not have a material impact to our debt obligations due to the fixed nature of our long-term debt obligations, except for the interest expense associated with our credit facility, which bears interest at floating rates, plus applicable margins, based on either the prime rate or LIBOR. As of December 31, 2003, the credit facility had an effective interest rate of 5.96%. Our credit facility was fully paid off in February 2004 with the proceeds from the convertible debenture offering. The fair market value of our long-term fixed interest rate debt is subject to interest rate risk. Generally, the fair market value of fixed interest rate debt will increase as interest rates fall and decrease as interest rates rise. These interest rate changes may affect the fair market value of the fixed interest rate debt but does not impact our earnings or cash flows.

The fair market value of our senior notes is based on quoted market prices. The estimated fair value of our senior notes as of December 31, 2003 was approximately $24.4 million. Our senior notes will be fully redeemed in March 2004 with the proceeds from the convertible debenture offering.

Foreign Currency Risk

Prior to December 31, 2002, all of our recognized revenue had been denominated in U.S. dollars, generated mostly from customers in the U.S., and our exposure to foreign currency exchange rate fluctuations had been minimal. However, commencing in fiscal 2003, as a result of the combination, approximately 15% of our revenues and approximately 18% of our costs were in the Asia-Pacific region, and a large portion of those revenues and costs were denominated in a currency other than the U.S. dollar, primarily the Singapore dollar, Japanese yen and Hong Kong and Australian dollars. As a result, our operating results and cash flows will be impacted due to currency fluctuations relative to the U.S. dollar. Going forward, we continue to expect that approximately 15% of our revenues and costs will continue to be generated and incurred in the Asia-Pacific region in currencies other than the U.S. dollar, similar to 2003.

Furthermore, to the extent that our international sales are denominated in U.S. dollars, an increase in the value of the U.S. dollar relative to foreign currencies could make our services less competitive in the international markets. Although we will continue to monitor our exposure to currency fluctuations, and when appropriate, may use financial hedging techniques in the future to minimize the effect of these fluctuations, there can be no assurance that exchange rate fluctuations will not adversely affect our financial results in the future.

Commodity Price Risk

Certain operating costs incurred by us are subject to price fluctuations caused by the volatility of underlying commodity prices. The commodities most likely to have an impact on our results of operations in the event of significant price changes are electricity and supplies and equipment used in our IBX hubs. We are closely monitoring the cost of electricity, particularly in California. We do not employ forward contracts or other financial instruments to hedge commodity price risk.
