Arista Networks (ANET) Stock Forecast & Price Target

Arista Networks is benefiting from exceptionally strong AI infrastructure demand, with 3Q26 revenue of $3.66bn rising 58.5% Y/Y and non-GAAP EPS of $1.20 beating guidance, while gross margin held at 64% and operating margin reached 49.1%. Its outlook is reinforced by conservative-looking management guidance for FY27 growth of 38%-40% to about $18.5bn, supported by AI Fabric revenue expected to double to ~$7bn, Campus revenue to grow ~60% to ~$2bn, and the rest of the business still expanding roughly 11%. The company also shows durable financial strength through $14.4bn of cash and investments, no debt, and $11.4bn of purchase commitments and inventory build, which indicate demand visibility, supply security, and continued share gains across cloud and enterprise customers.

Arista Networks is facing a negative outlook because supply bottlenecks in silicon, memory, and optics could limit shipments while inflation in component costs threatens to push gross margin toward the low end of 62% to 64%. Intensifying competition from NVIDIA’s Ethernet offerings, Cisco, white-box suppliers, and integrated electrical-optical vendors such as Marvell-Lumentum could pressure market share and pricing, especially given concentration among top customers and reliance on AI/cloud spending. In addition, R&D spending above the 9% to 11% framework or heavier optics investment could weigh on the roughly 49% operating margin, leaving less room for earnings durability.
