Key Q&A
Q:What are the factors influencing whether Arista will gain 1 or 2 additional 10% customers?
A:Factors include meeting acceptance criteria, timing, demand, supply chain allocation, and inflation. The final number depends on these variables, but demand is present.
Q:Why is Arista guiding 25% growth for the year despite a 30% growth outlook for Q1?
A:The 25% growth guidance reflects a realistic view of shipments and demand, considering variables like data center construction, power availability, and new AI-related use cases. The growth is also impacted by the law of large numbers as the company scales.
Q:What is the revenue and gross margin impact of memory dynamics and constraints?
A:Memory shortages and exponentially higher prices are impacting costs. Arista has absorbed costs in the past but expects challenges to persist. The gross margin guide of 62%-64% remains unchanged, with efforts to mitigate pressures.
Q:What is the contribution of AI to Arista's revenue and its impact on non-AI growth?
A:AI is expected to contribute $3.25 billion in 2026, with scale-up networking opportunities expected to ramp in 2027. Non-AI growth appears muted, with low single-digit growth expected.
Q:How is Arista participating in the build-outs of model builders like Anthropic?
A:Arista is working with multiple model builders and cloud titans to provide network infrastructure for AI clusters. The company is focusing on multiprotocol algorithms and distributed networks across multiple locations.
Q:What is the outlook for product deferred revenue?
A:Product deferred revenue depends on acceptance criteria and customer timing. It may release in larger deployments or gradually, but it is difficult to predict exact timing or amounts.
Q:What is the role of AMD in Arista's growth?
A:AMD is becoming a preferred accelerator in 20%-25% of deployments, favoring Arista's open standards and multi-vendor configurations. This is a growing area of collaboration.
Q:What is Arista's strategy for scale across networks?
A:Arista is focusing on coherent long-haul optics and high-bandwidth DCI routing for scale across networks. The 7800 spine chassis is the flagship platform for these configurations.
Q:What is the demand outlook for high-speed switching products addressing Agentic AI?
A:Agentic AI applications are driving demand for high-speed switching products, with growth expected in both cloud and enterprise sectors. AI is enabling better software and increasing demand for XPUs.
Q:How is Arista addressing memory shortages and price hikes?
A:Arista has absorbed costs but plans selective price increases for memory-intensive SKUs. Memory is included in purchase commitments, but shortages remain a challenge.
Q:Are hyperscalers pulling in demand ahead of time?
A:Hyperscalers are not nervous but are working closely with Arista, providing greater visibility into demand. There is no indication of significant pull-in of demand.
Q:Why is Arista guiding flat growth for 60% of its business?
A:Arista is not guiding flat growth but acknowledges that fast-growing segments like AI may overshadow other areas. Memory allocation and demand variability make precise guidance difficult.
Q:What is the update on Arista's 4 large AI customers?
A:Three customers have deployed over 100,000 GPUs and are expanding. The fourth customer is migrating from InfiniBand and is expected to reach 100,000 GPUs in 2026.
Q:What is the rationale behind Arista's new customer segmentations?
A:The segmentation reflects the growing focus on AI-centric customers and the shift in strategy of some customers like Oracle, which now have dual cloud and AI personalities.
Q:What are Arista's telemetry capabilities and their competitive differentiation?
A:Arista's telemetry capabilities include real-time streaming and AI-enhanced visibility for network and host-level data. This aids in debugging and optimizing network-host interactions.
Q:Review of Unclear Management Responses
A:Management avoided providing direct answers to questions about the exact timing and amounts of product deferred revenue release, the specific growth outlook for non-AI segments, and the precise impact of memory shortages on future operations. Responses were vague or lacked detailed data.
