Arista Networks released Q4 2025 results on Feb 12 and numbers came in stronger than expected. Revenue and earnings beat estimates, driven by demand for AI data center networking gear. Full-year revenue hit $9 billion (up 29%) with EPS at $2.32. They also raised 2026 revenue growth guidance to 25%, up from the previous 20% estimate, though they noted supply constraints might still be an issue. Deferred revenue jumped to $5.4 billion from $4.7 billion last quarter, so the order backlog looks solid. The stock trades at a premium 44x forward earnings, but analysts have a median price target of $177.50.
