Current report

We derive revenue primarily from customers’ use of our platform. Our revenue arrangements generally consist of usage-based fees, recurring subscription fees and fees for professional and other services. Usage-based fees are determined based on committed or actual platform usage, including measures such as data volume and requests, and are generally billed monthly in arrears. Many customers commit to minimum monthly usage or spending levels in exchange for more favorable pricing, and billings may exceed these minimum commitments based on actual usage. Certain arrangements include tiered pricing under which unit rates decrease as usage increases. For most usage-based arrangements, charges are determined independently each month based on usage during that month.

Current report

We also earn recurring revenue under fixed-fee subscription arrangements, which are generally billed in advance, and revenue from implementation, account management, enhanced support and other services, which may be billed on a one-time or recurring basis. Customer contracts typically have a term of 12 months. Customers may also purchase services online through our self-service payment and order process.

Current report

Revenue was $190.2 million for the three months ended September 30, 2026, compared to $158.2 million for the three months ended September 30, 2025, an increase of $32.0 million, or 20%. Revenue was $546.5 million for the nine months ended September 30, 2026, compared to $451.4 million for the nine months ended September 30, 2025, an increase of $95.1 million, or 21%. The increase in revenue was primarily attributable to expanded use of our platform and our portfolio of product suites by existing customers.

Current report

Research and development expenses were $42.8 million for the three months ended September 30, 2026 compared to $41.4 million for the three months ended September 30, 2025, an increase of $1.4 million, or 3%. The increase was primarily due to a $1.0 million increase in travel expenses and a $0.9 million decrease in capitalized software development costs. The increase was partially offset by a $0.8 million decrease in stock-based compensation expenses.

Current report

General and administrative expenses were $97.8 million for the nine months ended September 30, 2026 compared to $82.3 million for the nine months ended September 30, 2025, an increase of $15.5 million, or 19%. The increase was primarily due to a $12.3 million increase in stock-based compensation expenses, a $4.5 million increase in personnel-related costs, and a $0.8 million increase in corporate costs. The increase was partially offset by $2.4 million of primarily tax-related benefits.

Previous report

We no longer consider total customer count to be a key business metric. Management believes large customer count, which we continue to disclose, is a more appropriate indicator of the performance of our business, as a majority of our revenue is driven by large customers. Management no longer utilizes total customer count to manage or monitor the performance of our business.

Previous report

We derive our revenue primarily from usage-based fees earned from customers using our platform. The majority of our customers choose to utilize our platform for Network Services, for which we charge fees based on their committed or actual use of our platform, as measured in gigabytes and requests. Many of our customers generate billings in excess of their minimum commitment. We also earn fixed-rate recurring revenue from Security and Other products and services, including Compute and Observability, as well as professional and other services, such as implementation, account management and enhanced customer support. We charge a flat one-time or recurring monthly fee depending on the additional products and services selected. Typically, the term of our contracts with customers is 12 months and includes a minimum monthly billing commitment in exchange for more favorable pricing terms. In addition, customers can sign up online by providing their credit card information and agreeing to a minimum monthly fee.

Previous report

Our usage-based fees earned from customers using our platform are generally billed in arrears. Our security products are primarily annual subscriptions that are billed in advance. Many customers have tiered usage pricing which reflects discounted rates as usage increases. For most contracts, usage charges are determined on a monthly basis based on actual usage within the month and do not impact usage charges within any other month. Our larger customers often enter into contracts that contain minimum billing commitments and reflect discounted pricing associated with such usage levels.

Previous report

We report our revenue bythree product lines: Network Services, Security, and Other. Network Services include solutions designed to improve performance of websites, apps, application programming interfaces (“APIs”), and digital media. Security includes products designed to protect websites, apps, APIs and users. Other includes Compute solutions that allow developers to build and deploy modern web applications on our edge cloud platform, and Observability solutions that provide real-time logs, data and metrics streamed from our edge platform for actionable insights.

Previous wording

We emphasize retaining our customers and expanding their usage of our platform and adoption of our other products. Customers often begin with smaller deployments of one of our products and then expand their usage over time. Our platform includes a variety of offerings across Network Services, Security, and Other product lines, including Compute and Observability. As our customers mature, we assist them in expanding their use of our platform, including the use of additional offerings beyond content delivery or security. In addition, given that customer acquisition costs are incurred largely for acquiring and initial onboarding, we may gain operating leverage to the extent that existing customers expand their use of our platform and products. Our ability to retain customers and expand their usage could be impaired for a variety of reasons, including a customer moving to another provider or reducing usage within the term of their contract. Even if our customers expand their usage of our platform, we cannot guarantee that they will maintain those usage levels for any meaningful period of time or that they will renew their commitments.

We intend to continue expanding our efforts to attract customers outside of the United States by augmenting our sales teams and strategically increasing our presence in the number of markets in select international locations. Our international expansion, including our global sales efforts, continues to add increased complexity and cost to our business. This requires us to continue to expand our sales and marketing capabilities outside of the United States, increase the number of markets we have a presence in around the world to support our customers, and manage the administrative aspects of a global organization, each of which place a strain on our business and culture. In addition, our bandwidth costs are higher in markets outside of the United States and Europe, which may impact our gross margins.

We are closely monitoring various global conflicts and developments, including, but not limited to, the conflict between Russia and Ukraine, conflicts in the Middle East, including the recent military conflict involving Iran, the United States, and Israel, and their global impacts. While the conflicts are still evolving and the outcomes remain highly uncertain, we do not believe these or other conflicts will have a material impact on our business and results of operations. We do not have Points of Presence (“POPs”) in Russia, Ukraine, Iran, or Israel. However, some threat actors now engage and are expected to continue to engage in cyber-attacks, including without limitation nation-state actors for geopolitical reasons and in conjunction with military conflicts and defense activities. During times of war and other major conflicts, we, the third parties upon which we rely, and our customers may be vulnerable to a heightened risk of these attacks, including retaliatory cyber-attacks, that could materially disrupt our systems and operations, supply chain, and ability to produce, sell and distribute our goods and services. If such conflicts continue or worsen, leading to greater global economic disruptions and uncertainty, our business and results of operations could be materially impacted.

Previous wording

We must continue to invest in our platform and network infrastructure to maintain our position in the market. We expect our revenue growth to be dependent on an expanding customer base and continued adoption of our edge cloud delivery, security, and other products and services. In anticipation of winning new customers and staying ahead of our customers’ needs, we plan to continue to invest in order to expand the scale and capacity of our software-defined modern network. This could result in increased network service provider fees, which could adversely affect our gross margins if we are unable to offset these costs with revenue from new customers and increase revenue from existing customers. Our customers require constant innovation within their own organizations and expect the same from us. Therefore, we will continue to invest in resources to enhance our development capabilities and introduce new products and features on our platform. We believe that investment in research and development will contribute to our long-term growth but may also negatively impact our short-term profitability.

Previous wording

Developers use our platform to build custom applications and require a state-of-the-art infrastructure to test and run these applications. We will continue to invest in our network infrastructure by strategically increasing our POPs. We also anticipate making investments in upgrading our technology and hardware to continue providing our customers a fast and secure platform. Our gross margins and operating results are impacted by these investments. As we continue to experience growth, we may face challenges managing adequate server capacity in our POPs due to potential component delays, shortages, price increases, hardware efficiencies gained through internal development, or any potential changes in server architecture, including due to technological advances or obsolescence. If we have server asset levels in excess of forecasted network capacity needs, we have in the past and may need to continue to write-down or write-off server assets. Conversely, if we underestimate network capacity needs, we may in future periods be unable to meet demand and be required to incur higher costs to secure necessary parts and components of our servers.

In addition, international trade disputes may further disrupt or delay our supply chain for these components or lead to pricing increases. For example, the United States has imposed or indicated an intention to impose tariffs on certain countries which may lead to retaliatory actions such as counter-tariffs and increase production costs and disruptions in our supply chain. The United States and other jurisdictions have also leveraged various trade and value chain requirements, including on environmental and social criteria, which may make sourcing more costly, require us to change suppliers, or otherwise adversely impact our operations. Further, it is possible that government policy changes, including policy changes made with little to no advance notice, and related uncertainty about policy changes could increase market volatility. If our supply of certain components is further disrupted or delayed, there can be no assurance that we will be able to obtain adequate replacements for the existing components or that supplies will be available on terms and prices that are favorable to us, if at all. In the event that there are errors in software, failures of hardware, damages to a facility or misconfigurations of any of our services, whether caused by our own error, security breaches, third-party error, or natural disasters, we could experience lengthy interruptions in our platform availability as well as delays and additional expenses in arranging new facilities and services. In addition, there can be no assurance that we are adequately prepared for unexpected increases in bandwidth demands by our customers, particularly when we or our customers experience cyber-attacks. The bandwidth we have contracted to purchase may become unavailable for a variety of reasons, including service outages, payment disputes, network providers going out of business, natural disasters, networks imposing traffic limits, or governments adopting regulations that impact network operations.

Historically our revenue has been driven primarily by a subset of our customers, our large customers, who have leveraged our platform substantially from a usage standpoint. We believe that the recruitment and cultivation of large customers is critical to our long-term success. Our large customer count is defined as customers with annualized current quarter revenue in excess of $100,000. This is calculated by taking the revenue we recognized for each customer in the current quarter and multiplying it by four. As of June 30, 2026, we had 624 of such large customers which generated 94% of the total annualized current quarter revenue for our total customers for the three months ended June 30, 2026. As of June 30, 2025, we had 622 of such large customers which generated 94% of the total annualized current quarter revenue for our total customers for the three months ended June 30, 2025.

Our LTM NRR removes some of the volatility that is inherent in a usage-based business model from the measurement of the NRR metric. We calculate LTM NRR by dividing the total customer revenue for the prior twelve-month period (“prior 12-month period”) ending at the beginning of the last twelve-month period (“LTM period”) minus revenue contraction due to billing decreases or customer churn, plus revenue expansion due to billing increases during the LTM period from the same customers by the total prior 12-month period revenue. For the trailing twelve months ended June 30, 2026 and 2025, our LTM NRR was 117.2% and 104.4%, respectively.

The majority of our revenue is usage based and changes in usage by our largest customers can create volatility in our revenue. We receive a substantial portion of our revenue from a limited number of customers and within a limited number of industries, such as media and entertainment. The length of our sales cycles, from initial evaluation to payment, can range from several months to well over a year and can vary substantially from customer to customer. Similarly, the onboarding and ramping process with new as well as existing large customers with new business can take several months and can be subject to delays for unanticipated reasons. The timing of new revenue from our sales efforts and changes in usage by our largest customers can make revenue difficult to predict.

Previous wording

During the three and six months ended June 30, 2026 and 2025, our revenue was primarily generated from transactions with existing customers, as revenue from new customers contributed less than 10% of our revenue. The proportion of the revenue contribution between new and existing customers is consistent with prior periods and typical customer behavior as customers tend to contribute more revenue over time as their use of the platform increases. The remainder of our revenue was generated by our other products and services, including support and professional services.

Current wording

During the three and nine months ended September 30, 2026 and 2025, our revenue was primarily generated from transactions with existing customers. This trend is consistent with prior periods and it represents a typical customer behavior as customers tend to contribute more revenue over time as their use of the platform increases.

Cost of revenue was $67.4 million for the three months ended June 30, 2026 compared to $67.6 million for the three months ended June 30, 2025, a decrease of $0.2 million, or 0.3%. The decrease was primarily due to a $2.6 million decrease in depreciation expense primarily due to a change in the useful life of our servers as well as a $2.5 million decrease in intangible asset amortization expense due to fully amortized assets. The decrease was partially offset by a $2.6 million increase in colocation costs, a $1.4 million increase in software costs, and a $0.9 million increase in personnel-related costs.

Current wording

Cost of revenue was $69.8 million for the three months ended September 30, 2026 compared to $65.9 million for the three months ended September 30, 2025, an increase of $3.9 million, or 6%. The increase was primarily due to a $4.0 million increase in colocation costs, a $1.5 million increase in software costs, a $1.3 million increase in personnel-related costs, a $0.5 million increase in amortization of capitalized software costs, and a $0.5 million increase in transit-related costs. The increase was partially offset by a $2.5 million decrease in intangible asset amortization expense due to fully amortized assets as well as a $2.0 million decrease in depreciation expense primarily due to a change in the useful life of our servers.

Cost of revenue was $132.2 million for the six months ended June 30, 2026 compared to $135.3 million for the six months ended June 30, 2025, a decrease of $3.1 million, or 2%. The decrease was primarily due to a $6.2 million decrease in depreciation expense primarily due to a change in the useful life of our servers as well as a $5.0 million decrease in intangible asset amortization expense due to fully amortized assets. The decrease was also due to a $1.6 million decrease in bandwidth costs, and a $0.4 million decrease in equipment purchases. The decrease was partially offset by a $4.4 million increase in colocation costs, a $2.6 million increase in software costs, a $1.9 million increase in personnel-related costs, a $0.8 million increase in amortization of capitalized software costs, and a $0.8 million increase in stock-based compensation expenses.

Current wording

Cost of revenue was $202.0 million for the nine months ended September 30, 2026 compared to $201.2 million for the nine months ended September 30, 2025, an increase of $0.8 million, or 0.4%.
