• Needham’s Ryan Koontz raised his price target from $165 to $185 following Q4 results and a ~6% bump in fiscal 2026 revenue guidance
• ANET posted 28.6% revenue growth over the last 12 months and a net margin of 42.8%, outpacing rival Ciena (CIEN) on both counts

Arista Networks has had a strong run of analyst attention lately. As of March 11, 2026, 93% of analysts covering the stock carry a positive rating — a figure that’s hard to ignore. The consensus price target sits at $177.50, implying upside of roughly 27.6% from current levels.

Arista Networks, Inc., ANET

That bullishness is tied closely to Arista’s fundamentals. Revenue grew 28.6% over the last 12 months, and the company posted a net margin of 42.8% in the same period. Those aren’t just good numbers — they’re consistently good numbers. The three-year average revenue growth came in at 27.3%, with an average margin of 41.1%.

For comparison, Ciena (CIEN) posted 26.5% revenue growth over the last 12 months and has a three-year average of just 11%. Ciena’s stock jumped 15% in a week after reporting record Q1 revenue growth of 33.1% year-over-year. But its current P/E has inflated following that rally, and its longer-term growth track doesn’t match Arista’s.

ANET trades at roughly 40x earnings. That’s not cheap. But analysts argue the premium is justified given the company’s software-driven margins and its position in AI networking infrastructure.

Analyst Upgrades and Price Targets

TD Cowen kicked off coverage of ANET in March with a “Buy” rating and a $170 price target. That adds to an already crowded bull camp on Wall Street.

In February 2026, Needham analyst Ryan Koontz kept his “Buy” rating and lifted his price target from $165 to $185. He pointed to Arista’s Q4 results, which included a roughly 6% increase in fiscal 2026 revenue guidance. Koontz flagged growing back-end networking market share and rising AI infrastructure spending as the two key drivers behind his optimism.

The company’s data-driven networking platform is seen as a key enabler for next-generation AI datacenters. Analysts view Arista as a preferred vendor for Ethernet-based scale-out switching — the kind of infrastructure that hyperscalers and cloud operators are actively building out.

Where Analysts See Risk

Not everything is straightforward. Some analysts have flagged skepticism around multi-tenant AI inference infrastructure, which is technically complex to build and run. That part of the market remains a question mark for Arista’s longer-term positioning.

Still, those concerns haven’t moved the needle much on overall sentiment. The analyst consensus remains firmly positive heading into the rest of fiscal 2026.

Arista’s most recent guidance raised fiscal 2026 revenue expectations by approximately 6%, following a Q4 that came in ahead of expectations. TD Cowen’s initiation and Needham’s raised target both came after that update.
