Arista Networks Stock: Buy or Sell? | ANET STock Analysis

Parkev Tatevosian, CFAAug 26, 2026

Summary

Parkev analyzes Arista Networks' recent financial performance, highlighting that the company delivered $3 billion in revenue, exceeding its own guidance. Parkev emphasizes the remarkable 49.9% operating profit margin and the 10x revenue growth achieved over the last decade. Parkev observes that the management team has successfully secured supply to meet the surging demand for artificial intelligence infrastructure and data centers.

Parkev evaluates the company's efficiency, noting a Return on Invested Capital (ROIC) of approximately 32% compared to a Weighted Average Cost of Capital (WACC) of 12.12%. Parkev points out that this ratio, approaching 2.5:1, is among the best across all companies monitored. Parkev also notes that revenue growth accompanied by expanding margins is a strong indicator of robust organic demand and pricing power, rather than growth fueled by discounts.

Despite these strong fundamentals, Parkev expresses concern regarding the current valuation. Parkev calculated an intrinsic value of $130 per share using a discounted cash flow model, which remains significantly lower than the market price of $189. Parkev mentions that the forward price-to-earnings ratio of 37 is near historical highs, leading to the decision to downgrade the stock from a borderline buy to a hold.

Arista Networks (ANET): Parkev rates this stock as a hold because the market price of $189 has outpaced the calculated intrinsic value of $130. Parkev highlights that the company is a best-in-class performer with nearly 50% operating margins and strong AI-driven tailwinds. Parkev notes that while the business is booming, the forward P/E of 37 suggests the valuation is currently stretched, though Parkev admits to low conviction in this hold rating because company prospects continue to be revised upward.

Mentioned Stocks

ANET
Sentiment: HOLD

Reasoning: Parkev downgraded the stock to a hold because the current market price of $189 is significantly higher than the calculated intrinsic value of $130. Parkev notes that while Arista Networks has excellent fundamentals, including a 50% operating margin and a 32% ROIC, the forward P/E of 37 indicates a stretched valuation. Parkev expresses low conviction in this hold rating as the rapid acceleration of AI demand often leads to upward revisions of the company's prospects.
