Why It's Moving

Shares jump after Arista lifts 2025 revenue guide and projects faster AI growth — management signals sustained momentum
Arista’s shares moved this week after the company reported third-quarter results and raised full‑year revenue guidance, driven by stronger-than-expected demand for AI and campus networking products. Management’s updated AI revenue targets and multi‑year growth outlook shifted investor focus from near‑term cyclicality to durable, AI‑led expansion.
- Earnings and guidance: Arista reported Q3 2025 results and on the conference call raised its full‑year 2025 revenue guidance to ~25%, up from its prior ~17% target, implying the business is accelerating versus earlier expectations and easing concerns about a slowdown.
- AI revenue ramp: Management now expects AI-related revenue to grow sharply — management moved the 2026 AI target materially higher (from about $1.5B this year toward a ~$2.75B+ run rate next year), signaling AI will become a much larger share of revenue and underlining higher‑margin, secular demand drivers for Arista’s switching and software portfolio.
- Longer-term outlook and product strength: Executives said Arista will exceed targets in both AI and Campus product lines and reiterated multiyear “mid‑teen” growth targets beyond 2026, indicating confidence in sustainable demand from hyperscalers and enterprise campus upgrades rather than a one‑time cyclical bump.
