Overview

We were founded in 2001 as a provider of CDN services to deliver digital content over the Internet. We began development of our infrastructure in 2001 and began generating meaningful revenue in 2002. Today, we operate a globally distributed, high-performance computing platform (our global computing platform) and provide a suite of integrated services including content delivery, web and video content management, mobility, web application acceleration, cloud storage, and related consulting services that enable companies and other organizations to create, manage, and deliver a global digital presence.

The integrated suite of services that we offer collectively comprises our Orchestrate Platform. We provide the Orchestrate Platform as SaaS and IaaS, which other than content delivery services, are referred to collectively as VAS. We offer VAS both collectively as the end-to-end Orchestrate Digital Presence Platform and individually for customers that may not be inclined or able to adopt the entire platform.

The Orchestrate Platform and services help our customers optimize and streamline their online digital presence across web, mobile, social and large screen channels. The Orchestrate Platform and services enable our customers to remove the complexity of creating, managing, delivering and optimizing their digital presence, which helps them to deliver a high quality online media experience, improve brand awareness, drive revenue and enhance their customer relationships. The Orchestrate Platform and services provide advanced features which include website content management, personalization and targeting, video publishing, mobile enablement, content delivery, transcoding and cloud storage, combined with social media integration and reporting analytics. These services are provided through the cloud and leverage our global computing platform, which provides highly available, highly redundant storage, bandwidth and computing resources, as well as connectivity to last-mile broadband network providers. Our professional consulting services team helps organizations assess their digital presence requirements and improve their digital presence activities.

We derive revenue primarily from the sale of the Orchestrate Platform and its components as managed services. We also generate revenue through the sale of professional services and other infrastructure services, such as transit and rack space services.

We provide our services to customers that we believe view Internet, mobile and social initiatives as critical to their success, including traditional and emerging media companies operating in the television, music, radio, newspaper, magazine, movie, videogame, software and social media industries, as well as to enterprises, technology companies, and government entities conducting business online. Our offerings enable organizations to remove the complexity of creating, managing, delivering and optimizing their digital presence by streamlining

processes and optimizing business results across all customer interaction channels which helps them to deliver a high quality online media experience, improve brand awareness, drive revenue and enhance their customer relationships.

We provide services to customers in three geographic areas - North America, EMEA, and Asia Pacific, including Japan. As of December 31, 2012, we had 1,451 active customers worldwide.

In addition to expanding our suite of VAS, we continue to expand the capacity and capabilities, and to enhance the performance and efficiency, of our global computing platform. Although we believe that we may have improved margins in our content delivery services as we expand our customer base and use a greater proportion of our capacity, we expect the majority of our margin increases to result from our VAS increasing as a percentage of our revenue.

On November 26, 2012, we announced the appointment of Robert A. Lento as interim Chief Executive Officer effective immediately. We had previously announced on November 1, 2012 that Jeffrey W. Lunsford would be stepping down as our Chief Executive Officer in January 2013 and that an executive search firm was engaged to recruit his successor. On January 22, 2013, we announced that the board of directors completed its executive search and appointed Mr. Lento as our President and Chief Executive Officer and that Mr. Lunsford had tendered his resignation as a board member and Chairman of the Board. On February 12, 2013, we announced George E. Vonderhaar as Chief Sales Officer and recently appointed Jonathan Smith as Managing Director and Vice President of Europe, Middle East and Africa. On February 19, 2013, we announced the appointment of Walter D. Amaral to serve as our non-executive Chairman of the Board. Mr. Amaral fills the Chairman role vacated by the resignation of Mr. Lunsford. We also announced the appointments of Charles Kirby Wadsworth as our Chief Marketing Officer on June 25, 2012 and Indu Kodukula as our Chief Operating Officer on October 29, 2012.

During 2012, we completed two previously announced stock repurchase plans and commenced a third. On September 12, 2011, our Board authorized and approved a repurchase plan that authorized us to purchase up to $25 million of our shares of common stock, exclusive of any commissions, markups or expenses, from time to time through March 12, 2012. During the period September 12, 2011 through March 12, 2012, we purchased and cancelled approximately 9.7 million shares of common stock for approximately $25.0 million ($25.2 million including commissions) under the initial repurchase plan.

On May 3, 2012, we announced a second common stock repurchase plan that authorized us to repurchase up to $15 million of our shares of common stock, exclusive of any commissions, markups or expenses, from time to time through December 15, 2012. During the year ended December 31, 2012, we purchased and cancelled approximately 5.7 million shares of common stock for approximately $15.0 million ($15.1 million including commissions) under the second repurchase plan. On October 29, 2012, our Board of Directors authorized and approved a third common stock repurchase plan that authorized us to repurchase up to $10 million of our shares of common stock, exclusive of any commissions, markups or expenses, from time to time through May 9, 2013. Any repurchased shares will be cancelled and return to authorized but unissued status. During the three months ended December 31, 2012, we purchased and cancelled approximately 2.2 million shares under the third repurchase plan for approximately $4.6 million including commissions.

On August 31, 2012, the Court of Appeals for the Federal Circuit issued its opinion in our on-going patent litigation with Akamai. The Court of Appeals stated that the trial court correctly determined that we did not directly infringe Akamai's 6,108,703 patent and upheld the trial court's decision to vacate the original jury's damages award. The court also held that we did not infringe Akamai's 6,553,413 or 7,103,645 patents. A slim majority in this three-way divided opinion also announced a revised legal theory of induced infringement, remanded the case to the trial court, and gave Akamai an opportunity for a new trial to attempt to prove that we induced our customers to infringe Akamai's patent under the Court of Appeals' new legal standard. On December 28, 2012, we filed a petition for writ of certiorari to the United States Supreme Court to appeal this

sharply divided Court of Appeals decision and will seek to stay any proceedings at the trial court until the Supreme Court rules on that petition. Akamai then filed a cross petition for consideration of the Court of Appeals standard for direct infringement. Just as we have successfully shown that we do not directly infringe Akamai's patent, we firmly believe that we ultimately would be successful in showing we do not infringe Akamai's patent under the Court of Appeals majority's new induced infringement theory, and we will continue to vigorously defend against the allegation. We do not believe a loss is probable and therefore no provision for this lawsuit is recorded in our financial statements. For additional information, please see "Legal Proceedings" in

In May 2010, we made a strategic investment in Gaikai, a private cloud-based gaming technology company. In August 2012, Sony acquired Gaikai and we recorded a gain on sale of our cost basis investment in Gaikai of $9.4 million, which has been reflected in other income (expense) in the accompanying consolidated statements of operations for the year ended December 31, 2012. The carrying value of the Gaikai cost basis investment as of the sale date was approximately $2.0 million. The aggregate selling price was $11.4 million, consisting of $10.2 million of cash received and $1.2 million held in escrow for a period of up to 15 months to cover any potential indemnification claims. As of December 31, 2012, we are not aware of any potential indemnification claims that are expected to reduce the amount received from escrow and have recorded a current receivable of $1.2 million which is included in prepaid expenses and other current assets in the accompanying consolidated balance sheet for the year ended December 31, 2012.

The following table sets forth our historical operating results, as a percentage of revenue for the periods indicated.

Traffic on our network and our VAS offerings continued to grow during the year ended December 31, 2012. This traffic growth was primarily the result of growth in the traffic delivered to existing customers and to a lesser extent to new customers. Our content delivery revenue is generated by charging for traffic delivered. While our traffic continued to grow, our CDN revenue decreased approximately $4.8 million during 2012 when compared to 2011. The decrease was primarily due to lower reseller revenue and other non-traffic related revenue. Our VAS revenue represented substantially all of our revenue growth during the year ended December 31, 2012. During 2012, we continued to add new customers, experienced some attrition and elected not to renew some customers as we continue to focus on customer quality. Our average number of products per customer during the three month period ended December 31, 2012 was 1.8. For new customers added during the quarter we averaged 2.2 products. We continue to have success selling new products to our customer base.

Our international revenue continued to grow in 2012, and we expect this trend to continue as we focus on our strategy of expanding our network and customer base internationally. For the years ended December 31, 2012, 2011 and 2010, respectively, revenue derived from customers outside North America accounted for approximately 31%, 30% and 27% respectively, of our total revenue. For the years ended December 31, 2012, 2011 and 2010, respectively, we derived approximately 47%, 50% and 57%, respectively of our international

revenue from EMEA and approximately 53%, 50% and 43%, respectively of our international revenue from Asia Pacific. We anticipate that our Asia Pacific revenue may continue to grow as a percentage of our total international revenue. During 2012, two countries, Japan and the United States accounted for 10% or more of our total revenues. No single country outside of the United States accounted for 10% or more of our total revenues during the years ended December 31, 2011 and 2010. We expect international revenue to continue to increase in absolute dollars in 2013. Our business is managed as a single segment, and we report our financial results on this basis.

During any given fiscal period, a relatively small number of customers typically account for a significant percentage of our revenue. For example, in 2012, sales to our top 10 customers, in terms of revenue, accounted for approximately 33% of our total revenue. During 2011 and 2010, revenue generated from sales to our top 10 customers, in terms of revenue, accounted for approximately 34% respectively, of our total revenue. During 2012 and 2011, we had one customer, Netflix, who accounted for more than 10% of our total revenue. For each of the years ended December 31, 2012 and 2011, Netflix represented approximately 11% of our total revenue. During 2010, we had no customer that accounted for more than 10% of our total revenue. In 2013, we anticipate our top 10 customer concentration levels will be consistent with 2012. In the past, the customers that comprise our top 10 customers have continually changed, and our large customers may not continue to be as significant going forward as they have been in the past.

In addition to selling to our direct customers, we maintain relationships with a number of resellers that purchase our services for resale to their customers. Revenue generated from sales to reseller customers was approximately 3%, 4%, and 5%, respectively of our total revenue for the years ended December 31, 2012, 2011, and 2010, respectively.

We occasionally generate revenue from certain customers that are entities related to certain of our executive officers and directors. For the year ended December 31, 2012, revenue generated from these related party transactions was approximately 1% of our total revenue. For the year ended December 31, 2011, revenue generated from these related party transactions was less than 1% of our total revenue. For the year ended December 31, 2010, we did not generate any revenue from related parties.

In addition to these revenue-related business trends, our cost of revenue increased in absolute dollars and decreased as a percentage of revenue in 2012 when compared to 2011. The increase in absolute dollars was primarily due to increased payroll and related employee costs for our operations personnel, increased professional fees, and increases in other costs associated with the delivery of our services, as well as additional fees and licenses. These increases were offset by decreased bandwidth and co-location costs, which were primarily due to lower transit costs, offset by an increase in paid peering. In addition, 2012 includes a full year of cost of revenue for Clickability, Inc. (Clickability) and AcceloWeb (IL) Ltd. (AcceloWeb) compared to 2011 cost of revenue which includes eight months for Clickability and AcceloWeb which were both acquired in May 2011.

We enter into contracts with third party network and data center providers, with terms typically ranging from several months to several years. Our contracts related to transit bandwidth provided by network operators generally commit us to pay a fixed monthly fee or monthly fees plus additional fees for bandwidth usage above a specified level. We entered into an agreement with Global Crossing in January 2009 for use of private lines for additional bandwidth and backbone services with a term of four years from installation. We executed subsequent amendments in September 2009, March 2011 and January 2012 for additional bandwidth and backbone services. The agreement and subsequent amendments required substantial prepayment for such services, and the amendments extended the original term for some services through June 2014. In addition to purchasing services from communications providers, we connect directly to approximately 600 broadband ISPs, generally without either party paying the other. This industry practice, known as settlement free peering, benefits us by allowing us to place content objects directly on user access networks, which helps us provide higher performance delivery for our customers and eliminate paying transit bandwidth fees to network operators. This practice also benefits the ISP and its customers by allowing them to receive improved content delivery through our local servers and

eliminate the cost of transit bandwidth associated with delivery receipt of the traffic. We do not consider these relationships to represent the culmination of an earnings process. Accordingly, we do not recognize as revenue the value to the ISPs associated with the use of our servers nor do we recognize as expense the value of the bandwidth received at discounted or no cost. These peering relationships are mutually beneficial and are not contractual commitments. In addition to settlement free peering, we incur costs for non-settlement free peering as well as costs associated with connecting to the ISPs.

During 2012, we continued to reduce our network transit bandwidth delivery costs per gigabyte transferred by entering into new supplier contracts with lower pricing and amending existing contracts to take advantage of price reductions from our existing suppliers associated with higher purchase commitments. While we had increased traffic delivered over our network, our total transit bandwidth delivery costs decreased during 2012. We anticipate our overall transit bandwidth delivery costs will continue to increase in absolute dollars as a result of expected higher traffic levels, and we expect this increase to be partially offset by continued reductions in bandwidth costs per unit. We expect that our overall transit bandwidth delivery costs as a percentage of revenue will increase in 2013 compared to 2012.

For the year ended December 31, 2012, operating expenses increased in absolute dollars and increased as a percentage of revenue compared to the year ended December 31, 2011. This increase was primarily due to increased sales and marketing expenses, increased general and administrative expenses, increased research and development costs, and increased non-network related depreciation and amortization. The increase in sales and marketing expenses was primarily due to increased payroll and related employee costs, due to increased staffing, increased travel, increased professional fees, and increased facility and facility-related costs, offset by a decrease in share-based compensation. The increase in general and administrative expenses was primarily due to increased professional fees, primarily due to increased consulting and outside professional services, legal fees associated with intellectual property and general corporate legal matters, and recruiting costs. The increase in research and development costs was primarily due to increased payroll and related employee costs due to increased staffing. The increase in non-network related depreciation and amortization was due to increased amortization of intangible assets from our business acquisitions and administrative depreciation and amortization. For the year ended December 31, 2011, operating expenses included approximately eight months of operating expenses from our May 2011 acquisitions of Clickability and AcceloWeb.

We make our capital investment decisions based upon careful evaluation of a number of variables, such as the amount of traffic we anticipate on our network, the cost of the physical infrastructure required to deliver that traffic, and the forecasted capacity utilization of our network. Our capital expenditures have varied over time, in particular, as we purchased servers and other network equipment associated with our network build-out. For example, in 2012, 2011, and 2010, we made capital purchases of $18.4 million, $30.4 million, and $33.5 million, respectively, which represented 10%, 18%, and 22%, respectively, of total revenue for each of those years. We expect to have ongoing capital expenditure requirements, as we continue to invest in, refresh and expand our global computing platform.

Our future results will be affected by many factors identified in the section captioned "Risk Factors," in this annual report on Form 10-K, including our ability to:

• increase our revenue by adding customers and limiting customer cancellations and terminations, as well as increasing the amount of monthly recurring revenue that we derive from our existing customers;

• manage the prices we charge for our services, as well as the costs associated with operating our network in light of increased competition;

• successfully manage our litigation with Akamai to a favorable conclusion;

• prevent disruptions to our services and network due to accidents or intentional attacks;

• successfully integrate the businesses we have acquired; and

• successfully manage the disposition of businesses we have divested from.

As a result, we cannot assure you that we will achieve our expected financial objectives, including positive net income.

Critical Accounting Policies and Estimates

The preparation of consolidated financial statements and related disclosures in conformity with U.S. generally accepted accounting principles requires management to make judgments, assumptions, and estimates that affect the amounts reported in the consolidated financial statements and accompanying notes. Note 2 to the consolidated financial statements describes the significant accounting policies and methods used in the preparation of the consolidated financial statements. The accounting policies described below are significantly affected by critical accounting estimates. Such accounting policies require significant judgments, assumptions, and estimates used in the preparation of the consolidated financial statements, and actual results could differ materially from the amounts reported based on these policies.

Revenue Recognition

We primarily derive revenue from the sale of content delivery and value-added services to our customers. Our customers generally execute contracts with terms of one year or longer, which we refer to as recurring revenue contracts or long-term contracts. These contracts generally commit the customer to a minimum monthly level of usage with additional charges applicable for actual usage above the monthly minimum commitment. We define usage as customer data sent or received using our content delivery service, or content that is hosted or cached by us at the request or direction of our customer. We recognize the monthly minimum as revenue each month provided that an enforceable contract has been signed by both parties, the service has been delivered to the customer, the fee for the service is fixed or determinable, and collection is reasonably assured. Should a customer's usage of our services exceed the monthly minimum commit, we recognize revenue for such excess in the period of the usage. For annual or other non-monthly period revenue commitments, we recognize revenue monthly based upon the customer's actual usage each month of the commitment period and only recognize any remaining committed amount for the applicable period in the last month thereof.

We typically charge the customer an installation fee when the services are first activated. We do not charge installation fees for contract renewals. Installation fees are recorded as deferred revenue and recognized as revenue ratably over the estimated life of the customer arrangement. We also derive revenue from services and events sold as discrete, non-recurring events or based solely on usage. For these services, we recognize revenue after an enforceable contract has been signed by both parties, the fee is fixed or determinable, the event or usage has occurred, and collection is reasonably assured.

We have on occasion entered into multi-element arrangements. Revenue arrangements with multiple deliverables are divided into separate units of accounting if each deliverable has stand-alone value to the customer and there is objective and reliable evidence of the fair value of each deliverable. . . .
