Goldman Sachs has reaffirmed its "Buy" recommendation on Arista Networks (ANET.US), setting a 12-month price target of $225, which is based on a 36 times forward price-to-earnings multiple extending through next year. Against the September 4 closing price of $193.78, this implies an upside potential of approximately 16.1%. The firm highlighted that the company has reaffirmed its 2026 revenue and margin guidance, underpinned by improved supply chain visibility and robust demand across two key strategic areas: AI infrastructure and enterprise campus deployments.

According to the research note, Arista Networks' management indicated during the Communacopia + Technology Conference that the company raised its 2026 revenue guidance to $12.6 billion in the second quarter of 2026, driven by easing supply chain constraints and better demand visibility. Management has maintained its gross margin guidance of 62% to 64%, supported by roughly 30 basis points of tariff refunds this year and targeted price increases designed to offset rising component costs, despite ongoing inflationary pressures and product mix shifts.

Management also disclosed that multi-year purchase commitments reached $9.7 billion in the second quarter of 2026, reflecting strong underlying demand rather than merely higher component prices. The company is willing to increase investments in long-lead-time components, as product mix flexibility and visibility into customer product roadmaps help mitigate the risk of component obsolescence. Goldman Sachs believes that price increases and supply chain efficiency improvements could help the company sustain gross margins in 2027 at levels comparable to 2026, even as it faces a higher comparison base due to the approximately 30 basis points of tariff refunds recognized in 2026.

At the product level, Goldman Sachs pointed out that Arista Networks' EOS operating system represents a significant competitive differentiator, enabling a unified software image across the entire product portfolio, while competitors often rely on different operating systems for various products. EOS delivers high reliability and consistency across hyperscale cloud provider routing, Neocloud, and enterprise environments. For Neocloud and enterprise customers, the manageability and quality derived from a unified software stack spanning campus and cloud scenarios represent a primary source of value. The firm also noted that operating at scale requires best-of-breed solutions, which positions ANET favorably against integrated alternatives that typically target lower-volume customers.

In the AI networking space, the company is witnessing robust demand across multiple segments, particularly in the backend networks connecting GPU accelerators. Scale-across deployments are also generating significant demand, as customers constrained by power, cooling capacity, and data center space need to expand clusters across multiple locations. Management also noted that deferred revenue conversion associated with newer AI deployments may continue to be uneven, as revenue recognition depends on customer acceptance and performance validation, while preparatory work such as data center construction, power, cooling, and cabling may also delay deployment timelines.

Regarding Neocloud customers, management indicated that this client segment represents an attractive growth area that values open, best-of-breed AI networking solutions, though Arista is also monitoring customer credit risk. On the Scale-up Ethernet front, the company believes this remains in its early development stages, but as the market transitions from proprietary interconnects to open standards, this area could emerge as a significant new growth vector in the medium term. The company expects this market to begin ramping in late 2027, with more substantial scale anticipated by early 2028.

In the enterprise campus market, the company is successfully extending its data center networking capabilities into this segment, which represents a substantial growth opportunity. Its value proposition aligns with the data center business, including product quality and the EOS software and CloudVision management software stack developed by the same engineering team. This growth is driven by two factors: cross-selling to existing data center customers and customer wins fueled by dissatisfaction with traditional vendors, with "campus-first" program wins continuing to increase.

Goldman Sachs noted that Arista Networks, as a leading brand switch supplier to U.S. hyperscale cloud providers, is well-positioned to benefit from continued data growth, workload migration from on-premises to public and hybrid cloud environments, and market demand for higher bandwidth, faster speeds, and lower latency. The firm indicated that within its coverage universe, ANET has the highest revenue exposure to cloud spending, with 48% of 2025 revenue derived from Cloud Titans business, of which META and MSFT account for 16% and 26% of total revenue respectively, while an additional 20% of revenue comes from second-tier cloud providers and service providers. The company is also leveraging its dominant position in data center switching to expand into other networking solutions, particularly enterprise networking areas such as campus switching, wireless, routing, and telemetry. The firm projects that driven by strong data center business growth and enterprise market expansion, the company is poised to deliver robust double-digit revenue and EPS growth over the coming years, while continuing to increase investments in R&D and sales and marketing, especially for building enterprise market sales capabilities.
