Arista Networks, Inc. ANET used its second-quarter call to emphasize that improved component access is converting strong demand into higher shipments across artificial intelligence (AI), data center, campus and routing.

Management raised its 2026 revenue outlook for the third time this year, while focusing on execution, customer mix and demand beyond AI fabrics.

ANET Raises Its 2026 Revenue Outlook

Chairperson and chief executive officer Jayshree Ullal said Arista now expects 2026 revenues of approximately $12.6 billion, representing 40% growth. The outlook is $1.1 billion above the May projection and $2.1 billion above the prior Analyst Day goal.

Chief financial officer Chantelle Breithaupt guided third-quarter revenues to approximately $3.3 billion, with a non-GAAP operating margin of 48% to 49% and non-GAAP earnings of $1.06 to $1.08 per share.

Second-quarter revenues reached $3.04 billion, ahead of the Zacks Consensus Estimate of $2.83 billion and up 37.7% year over year. Non-GAAP earnings rose 39.7% to $1.02 per share, beating the consensus estimate of $0.89.

Arista Expands Supply Commitments

President and chief operating officer Todd Nightingale said the company added suppliers, improved delivery terms and expanded manufacturing and distribution capacity. Arista now works with three contract manufacturers and three distribution facilities across the United States, Asia and Mexico.

Management secured memory supply for 2026 and extended visibility into 2027 across DDR4, DDR5 and NAND. It also established a liquid-cooling supply chain for next-generation AI systems.

Purchase commitments rose to $9.7 billion from $8.9 billion in the first quarter and about $3.6 billion a year earlier. Ullal cautioned that industry constraints could persist until 2028, despite Arista's progress.

ANET Builds Out Its AI Fabric Advantage

Ullal said cumulative Etherlink customers now exceed 100, up from four to five customers discussed in 2024. The company is extending its portfolio with the 7060XE7, which supports 1.6-terabit throughput, 100 terabits of system capacity and liquid-cooling options.

Co-founder, President and chief technology officer Kenneth Duda highlighted Smart System Upgrade, Multipath Reliable Connection and SRv6-based routing. Management framed those capabilities as tools to reduce downtime, avoid congestion and improve accelerator utilization.

Arista expects 1.6-terabit platforms to remain in trials during the second half of 2026, with production ramping in 2027. Ullal said initial evaluations involve a small number of large customers.

Arista Sees Broader Growth Beyond AI

A UBS analyst questioned why the higher annual outlook did not include a larger stated AI or campus target. Ullal responded that all product sectors should grow, while management retains flexibility to prioritize shipments based on supply.

A Raymond James analyst pressed on the incremental $1.1 billion. Ullal pointed to core data center front-end systems, enterprise demand, routing, campus and AI as contributors.

Breithaupt also cited new customer wins, international expansion and land-and-expand activity between campus and data center deployments. The guidance increase was broader than a single product cycle.

ANET Defends Its System-Level Approach

An Evercore ISI analyst asked whether rising AI-network complexity strengthens integrated systems relative to white-box alternatives. Ullal said simple deployments can still use lower-cost white-box equipment, but larger scale-out and scale-across networks require more software, reliability and traffic engineering.

A Morgan Stanley analyst asked why newer cloud operators choose Arista's blue-box systems. Ullal emphasized operating efficiency, EOS feature depth and reliability, while acknowledging that large customers with extensive engineering staffs may continue using white-box products.

A Wells Fargo analyst asked about customer concentration. Ullal said Microsoft and Meta remain key partners and expects one, and potentially two, customers to represent at least 10% of revenue as shipments scale.

Arista Keeps Execution at the Center

Management's tone remained confident on demand but measured on supply. Breithaupt said customer visibility remains about two quarters and the annual outlook reflects supply the company is confident it can secure.

The call left Arista focused on converting commitments into shipments, scaling new AI platforms and broadening growth across established networking categories without relaxing operating discipline.

Zacks Signals Show Mixed Style Support

ANET carries a Zacks Rank #2 (Buy), a favorable indicator tied to earnings-estimate revisions over the next one to three months. Its Growth Score of A is the strongest style signal, while the Value Score of F and Momentum Score of D indicate weaker positioning on those dimensions.
