Arista Networks Inc. (NYSE: ANET) doesn’t sell GPUs. It doesn’t build AI models. And it rarely grabs headlines like Nvidia (NASDAQ: NVDA) or Microsoft (NASDAQ: MSFT). Yet Arista has quietly become one of the most influential technology companies in the market. Strong Q2 results and higher guidance pushed the stock to record highs, rising 20% in the past five days versus a 1.7% gain for the S&P 500.

Three key numbers reveal why Arista is one of the most profitable and resilient players in the sector.

Looking for upside with lower volatility than individual stocks? The Trefis High Quality portfolio presents an alternative, having outperformed the S&P 500 and generated returns exceeding 91% since its inception. Separately, see What’s Happening With Joby Stock?

1. 40.3% Net Margin — Software-Level Profitability

Arista posted a 40.3% net margin in Q2—higher than Apple (NASDAQ: AAPL), Alphabet (NASDAQ: GOOG), or Microsoft. And it sells hardware.

The driver is Arista’s cloud-native EOS (Extensible Operating System), which turns traditional networking hardware into a software-defined platform. This enables high margins and steady, recurring demand from hyperscalers like Meta and Microsoft (together over 40% of revenue).

2. 54% Operating Cash Flow Margin — S&P 500 Royalty

More than half of Arista’s revenue becomes cash. Its 54% operating cash flow margin ranks in the top 5% of S&P 500 companies—including most SaaS firms. That cash fuels innovation, growth, and a balance sheet that’s already one of the strongest in tech.

3. $8.1 Billion in Cash, No Debt — Flexibility in Any Market

With $8.1 billion in cash (56% of assets) and zero debt, Arista can invest through downturns, defend its market position, and expand globally without relying on outside financing.

That strength has been tested:

    • COVID crash → fully rebounded in 5 months

    • 2022 inflation shock → fell 38%, recovered by early 2023

Valuation Is High, Execution Is Higher
Arista trades at 23.5x sales, 50.7x earnings, and 46.2x free cash flow—well above the S&P 500 averages. On paper, it resembles a SaaS company more than a traditional networking firm.

The difference is in execution. With entrenched demand from major cloud players, software-like margins, and a growing role in AI data centers, Arista is compounding its position in a fast-growing market.

The Bottom Line: Arista Is a Hidden Giant

Arista isn’t widely recognized outside of tech circles, but its profitability, balance sheet strength, and AI infrastructure role make it a key player in the sector. The stock isn’t cheap, and risks remain, but its performance has consistently backed up its valuation. For investors looking beyond chips and AI models, Arista offers exposure to the infrastructure enabling AI’s growth—and the market is starting to take notice.

That said, investing in a single stock can be risky. You could explore the Trefis Reinforced Value (RV) Portfolio, which has outperformed its all-cap stocks benchmark (combination of the S&P 500, S&P mid-cap, and Russell 2000 benchmark indices) to produce strong returns for investors. Why is that? The quarterly rebalanced mix of large-, mid- and small-cap RV Portfolio stocks provided a responsive way to make the most of upbeat market conditions while limiting losses when markets head south, as detailed in RV Portfolio performance metrics.
