Arista Networks files 10-Q: quarterly report (10-Q)
Overview
In a world where data is increasingly a precious commodity and competitive differentiator, Arista was founded to enable our customers to access all their centers of data in the quickest, most reliable, and secure manner. Over the last two decades, we have established ourselves as an industry leader in data-driven, client-to-cloud networking-as-a-service. Our “Centers of Data” strategy is a fundamental pivot from legacy, siloed networking to a unified, data-driven approach in which the network is a service that interconnects four primary domains: AI Centers, Data Centers, Campus Centers, and WAN Centers. Anchored by Arista’s state-oriented Extensible Operating System (EOS) and Network Data Lake (NetDL), our network-as-a-service platform delivers a seamless, consolidated networking experience regardless of data location.
Our solutions are differentiated because they:
• offer uncompromising reliability derived from the foundation of robust quality assurance capabilities, and a suite of automated diagnostics;
• are based on advanced open and standards-based technology that avoids what is often expensive vendor lock-in, and
• provide consistent real-time telemetry and intelligent automation to decrease the manual workload on the operator.
Our strategic differentiation enables us to deliver a comprehensive suite of products and services on a global scale. Through our network-as-a-service approach, we empower customers to seamlessly leverage their data across our entire platform. By combining world-class engineering with continuous innovation, we provide the predictable performance and simplicity needed to turn data into a sustainable competitive advantage in today’s AI-driven world.
The market for cloud networking is characterized by rapid technological evolution, intensifying competition, and the expansion of generative and agentic AI. To sustain our success and adapt to the market, we must increase sales in cloud, AI and enterprise data center Ethernet switching/routing markets, and campus workspace markets by leveraging our ability to rapidly develop new features and software applications. Our growth strategy relies on maintaining our agility and increasing our investment in research and development to deliver market-leading features to enhance the functionality of our existing cloud networking platform, expand our product offerings and build upon our technology leadership. In addition, we must continue to expand our global sales force and deepen our channel partnerships to reach new customers more effectively and increase sales to existing customers.
Historically, a limited number of customers have accounted for a significant portion of our revenue. Two of our customers accounted for more than 10% of our total revenue in each of the last three years. Sales to one end customer represented 16%, 15%, and 21% of our total revenue, and sales to the other end customer represented 26%, 20%, and 18% of our total revenue for the years ended December 31, 2025, 2024, and 2023, respectively. We have experienced unpredictability in the timing of orders from our high-volume customers, primarily due to the inherent complexity of large-scale orders and fluctuations in their specific demand. This includes reductions or shifts in their capital expenditure budgets, as well as the impact of their internal cost-reduction and efficiency initiatives. Furthermore, variability in customer concentration is driven by the timing of new product deployments, customer spending cycles, and the extensive periods required for evaluation, testing, and qualification. We expect this variability in concentration and sales timing to continue on both a quarterly and annual basis. Additionally, the pricing discounts typically required for these large-scale orders adversely impact our gross margins.
We believe an increased focus on the deployment of AI-enabled solutions by our large customers has accelerated the need for advanced technology offerings, including some offerings from potential new market entrants. This prioritization of AI related infrastructure investment has, at times, come in conjunction with a reduction or changes in the mix of previously planned purchases and various cost reduction measures by these customers, including optimization and increased efficiency in non-AI related capital expenditures. In addition, although the focus on deployment of AI-enabled solutions has driven increased demand for networking, the long-term trajectory is unknown. As such, demand estimates for our new products are difficult to forecast and can create volatility in our revenue.
We remain in a period of new product introductions and expanded use cases, particularly in the AI Ethernet market. This has resulted in increased customer trials and contracts with acceptance periods, and an increase in the volatility and magnitude of our evaluation inventory and product deferred revenue balances, which in turn may create variability in our revenue results on a quarterly and annual basis. In addition, if we are not able to satisfy the requirements under customer trials or contracts with acceptance periods, we may be required to accept product returns from our customers, which would prevent us from recognizing revenue on such transactions and may result in the write-down of inventory.
Macroeconomic Update
Global economic and business activities continue to face widespread macroeconomic uncertainties, including the effects of, among other things, inflation, monetary policy shifts, recession risks, supply constraints and potential supply chain disruptions, changes in government administration policy positions, and geopolitical pressures, including the war in Iran and international trade measures and tariff uncertainty.
Management is actively collaborating with contract manufacturers and suppliers to optimize our supply chain in response to component constraints, evolving international trade policies, and tariff uncertainties. Ongoing supply constraints and future trade measures have and could continue to adversely affect our supply chain stability and increase our product costs. We are maintaining a disciplined fulfillment cadence to ensure reliable inventory deployment. As we build capacity to meet escalating d emand, we are shipping products against previously committed demand/deployment plans and accelerating some shipments as needed. Simultaneously, we are balancing customers’ requirements and lead times against the availability and lead times of key components and products from our suppliers and contract manufacturers. Given the timing and prioritization of customer orders and shipment patterns, as well as the timing and outcome of customer trials and contracts with acceptance periods, near term revenue trends may not be reflective of current demand levels and may benefit from demand/deployment plans that have been previously committed.
