Memo

Arista Networks, Inc. (ANET). Latest full fiscal year: 2025; data up to 2026-09-30.

Figures computed from the financial statements: revenue 9.0 bn USD in 2025; YoY growth 28.6%; net margin 40.0%; ROE 33.5%.

Valuation cannot be computed from the available data.

Insufficient data for a verdict (valuation methods computed: 0 of at least 1).

Text generated deterministically from the figures shown; no language model. Not investment advice.

What supports the thesis

  • EBIT margin: 43.8%
  • FCF margin: 42.2%
  • Revenue CAGR 3Y: 27.1%
  • Revenue growth (YoY): 28.6%
  • Current ratio: 3.3x

What contradicts it

No signal among the computed factors. That is not an absence of risk: factors without data were not assessed, and business risks (margins, inventory, demand) are in the source-based analysis.

Not assessed (insufficient data or a ratio without meaning): Net debt / EBITDA, EV/Sales.

AI analysis

AI-generatedAI-generated analysis (Claude) from cited public sources; it may contain errors. Not investment advice. As of 27 Oct 2026 · Model: claude-haiku-5-5.

Possibly outdated: the newest document it read is from 05 Aug 2026; since then the company filed 10-Q (04 Nov 2026), 8-K (03 Nov 2026 · results).

In brief

Arista Networks (1, 3) supplies networking solutions for AI and data centers, reporting fiscal 2025 revenue of 9005.7 million USD and a gross margin of 64.1% 1. In the second quarter of 2026 revenue reached 3.036 billion USD, up 37.7% year over year 3. The company remains dependent on a few large customers that account for a substantial share of sales 1.

SWOT

Strengths

  • The company has a unified software platform with a single operating system, data lake and management tool, supporting product consistency 1.
  • Gross margins have remained stable in recent years, suggesting pricing discipline and a healthy product mix 1.
  • Recent quarterly results show solid growth in revenue and earnings per share 3.

Weaknesses

  • Revenue depends on a few large customers, which makes the timing of sales unpredictable 12.
  • The company relies on one main switching silicon supplier and on external partners for manufacturing 1.
  • Large customers receive more favourable terms, which can reduce margins in some quarters 1.

Opportunities

  • The shift to Ethernet in AI infrastructure across scale-up, scale-out and scale-across networks could open new orders 1.
  • Expansion into enterprise and a wider range of industries could reduce dependence on the largest customers 1.
  • A growing installed base could support recurring revenue from support and renewal contracts 1.

Threats

  • Cuts or shifts in capital spending by large customers could slow orders 12.
  • Tariffs and trade measures could raise costs and disrupt the supply chain 1.
  • New entrants and pricing pressure could reduce market share 1.

Risks

  • Customer concentrationhigh

    Two customers account for a large share of sales, and losing or delaying their orders could significantly affect quarterly revenue 1.

  • Dependence on one silicon supplierhigh

    A single main supplier provides switching chips, which could lead to delays or higher costs 1.

  • Tariffs and trade restrictionsmedium

    United States tariffs and retaliatory measures by other countries could affect costs and market access 12.

  • Revenue volatilitymedium

    Quarterly revenue can fluctuate widely, and forecasts for new products are difficult to make 1.

  • Security vulnerabilitiesmedium

    Defects or vulnerabilities in products could lead to security incidents and loss of customer confidence 1.

Investment thesis

What would need to be true (bull case)

  • If demand for AI infrastructure and the shift to Ethernet continue, the company could keep growing quickly, as recent quarterly growth suggests 3.
  • High gross margins and a unified software platform could support profitability even when cost pressures rise 1.
  • Diversification into enterprise customers and recurring services could stabilise long-term revenue 1.

What would break the thesis

  • If large customers cut AI investment or shift purchases to other vendors, revenue could fall sharply 12.
  • Pressure on memory and component costs could reduce gross margins in coming quarters 12.
  • Competition from integrated cloud systems and generic hardware could limit price increases 12.

The business

Arista Networks, Inc. describes its business as a networking-as-a-service platform built around its EOS operating system and NetDL data lake 1. Its Centers of Data strategy groups products into four domains: AI Centers, Data Centers, Campus Centers and WAN Centers 1. The company sells through a direct sales force and partners, while most products are manufactured by subcontractors 1.

Manufacturing is performed by contract partners such as Jabil, Sanmina and Foxconn Hon Hai in several countries in Asia and North America 1. The company keeps control over the bill of materials, qualified suppliers and test and quality programs 1.

Segments

Core (AI, Cloud and Data Center Networking)

This category accounted for about 65% of fiscal 2025 revenue and includes the Etherlink platforms and switches for AI Scale Out and Scale Across 1.

Market context

Demand from large customers depends on investment schedules for AI infrastructure, which can be volatile 12. If customer capital spending falls or shifts, orders and margins could be affected 1.

Trends

  • AI infrastructure and the move to Ethernettailwind

    The shift from InfiniBand to Ethernet for Scale Out and interest in Scale Across create share opportunities for the Etherlink solutions 1.

  • Customer concentrationheadwind

    Revenue depends on a few very large customers, and the timing of their orders can produce significant quarterly swings 12.

  • Component cost pressureheadwind

    Memory shortages and supply tensions could reduce gross margins, especially if costs cannot be passed on to customers 12.

  • Growing support servicesmixed

    Service revenue grows with the installed base and renewal contracts, which could stabilise long-term revenue 1.

Competitive position

The market is competitive, with pricing pressure and a risk of industry consolidation 1. Competitors include vendors offering cloud-focused combined hardware and software, and white-box systems with open-source operating systems 21.

The company differentiates through its single EOS operating system, the CloudVision management platform and round-the-clock support 1. Its main silicon supplier, Broadcom, is also a potential competitor if it sells directly to customers 1.

  • Cisco SystemsCSCO

    Indirect competitor in data center and campus networking equipment, referenced through the competitive pressures described in the filing 1.

  • BroadcomAVGO

    Principal switching silicon supplier that could become a competitor if it sells merchant silicon for white boxes directly to customers 1.

  • Cloud-focused hardware and software system vendors

    Large system vendors combining cloud hardware and software, described as an alternative to the company's products 2.

  • White-box producers with open-source operating systems

    Customers could buy generic hardware with open-source software, which could reduce market share 1.
