Is Arista Networks (ANET) Overvalued or Undervalued? A Complete Valuation Analysis 2026

The short answer

Short answer: Arista Networks looks overvalued at current levels. Compared with the recent share price of $141.75, the current DCF output near $83.08 suggests Arista Networks is about 70.6% overvalued on these cash flow assumptions. Arista Networks is being valued in the context of a business with gross margin near 63.5%, which helps show what kind of operating model investors are paying for. That leaves Arista looking rich unless the next leg of earnings or cash flow growth arrives fast enough to justify the current price.

Why valuing this kind of technology company is more complex than it looks

Arista Networks operates in Computer Hardware. Companies in this part of the market are usually valued on a mix of current earnings, expected growth, margin durability, and cash generation.

The reason this matters is simple. Two companies can show similar headline multiples and still deserve very different valuations because their margins, cash conversion, and growth durability are not the same.

What the numbers tell us

The first thing to notice with Arista is the gap between trailing and forward earnings valuation. Trailing P/E is near 50.8x while forward P/E is near 111.1x, which tells you the market is already underwriting a specific earnings path.

Arista's forward P/E is not offering much relief versus the trailing multiple, so the market may still be paying up before the earnings improvement is fully visible.
Arista's PEG ratio near 4.8x matters because it tests whether the earnings multiple is being balanced by a credible growth rate.
Arista's price to sales multiple near 18.4x needs to be read beside revenue growth near 28.6%, because rich revenue multiples only hold up when growth quality stays intact.

What would make it look cheaper
