Arista Networks Targets $12.6B as AI, Campus and Cloud Networking Growth Accelerates

Arista is targeting $12.6 billion in 2026 revenue , implying approximately 40% growth, while continuing to invest across AI, data-center switching, software, campus networking and routing. Improved supply visibility led Arista to raise annual guidance by more than $1 billion, while multiyear purchase commitments nearly tripled to $9.7 billion. The company maintained its 2026 gross-margin outlook of 62% to 64% despite ongoing component constraints. AI networking and campus expansion are major growth drivers: AI revenue is targeted at $3.5 billion, with scale-across networking representing about 30% of that figure, while the campus revenue target rose above $1.25 billion.

Arista Networks NYSE: ANET executives said the company is investing across its networking portfolio rather than making tradeoffs between AI and data-center switching, software, campus networking and routing, as it works toward its 2026 revenue outlook of $12.6 billion. Speaking at the Goldman Sachs Communacopia and Technology Conference, Chief Financial Officer Chantelle Breithaupt said the outlook implies roughly 40% growth and provides substantial absolute-dollar capacity for research and development. Arista generally targets R&D spending of 8% to 10% of revenue, she said.

Investments in hardware and software for large operators can flow into specialty cloud providers and enterprise deployments, he said.

Breithaupt said Arista raised its annual guidance by more than $1 billion after becoming more comfortable with supply availability and gaining greater order visibility. The company secured purchase commitments, received support from suppliers and had visibility into two quarters of purchase orders by the August timeframe, she said.

Availability can be affected by a range of items, from major components such as chips and memory to peripheral items including printed circuit boards and power cables. Arista’s multiyear purchase commitments nearly tripled to $9.7 billion, according to the discussion. Breithaupt characterized the increase as a demand signal rather than solely the result of component-price inflation. Chips have lead times of roughly 52 weeks, she said, prompting the company to make purchasing decisions well ahead of the order visibility it has in hand. The company is comfortable with that approach because its portfolio is relatively flexible and components can be used across products and customers, Breithaupt said. Duda added that common switch models and components serve multiple customer types and use cases, helping reduce potential inventory-obsolescence risk.

Arista maintained its 2026 gross-margin outlook of 62% to 64%. Breithaupt said customer mix remains a primary variable, while tariff refunds are expected to contribute about 30 basis points for the year. The company also implemented a targeted price increase for products with meaningful exposure to memory and other component-cost inflation. The increase was intended to offset inflation rather than expand margins, she said.
