Financial Highlights
Arista's financials demonstrate a masterclass in scaling high-margin technology. Revenue growth has been consistent, accelerating in the latter half of the decade as 100G/400G and now 800G cycles took hold. Net income has scaled from $58M in 2016 to over $3.5B in 2025 (extrapolated/reported), representing a massive CAGR that far exceeds the broader technology sector. Operating margins are resilient, typically staying above 30%, which highlights the efficiency of their fixed-cost leverage and high-value software component. The lack of long-term debt significantly lowers the risk profile and enhances net interest income. Profitability remains high despite aggressive R&D spending, which is a hallmark of a dominant industry leader.
