Simplify's Take
What believers are saying
- Q2 2026 revenue grew 37.7% year over year, with Q3 guidance at $3.3 billion.
- Management raised 2026 revenue guidance to $12.6 billion, implying 40% annual growth.
- ETM for VeloCloud ships in Q4 2026, opening campus and branch cross-sell.
What critics are saying
- Microsoft and Meta still dominate revenue concentration, tightening bargaining power in 2026.
- Broadcom-linked chip shortages and 52-week lead times cap shipments through 2026 and 2027.
- If AI capex slows, Arista's deferred revenue backlog converts slower and compresses valuation.
What makes Arista Networks unique
- Arista won Q2 2026 with $3.036 billion revenue and 49.9% operating margin.
- Its 7060XE7 1.6T platforms target rack-scale AI infrastructure, launched June 9, 2026.
- VeloCloud ETM adds unified zero-trust branch security, expanding Arista beyond data-center switching.

↓ -1%Tom Lee of Fundstrat has added Arista Networks and JPMorgan to his core stock ideas for 2026. Joseph Terranova of Virtus Investment Partners endorsed the Arista pick, citing the company's participation in AI networking infrastructure buildout and accelerating revenue growth. Kevin Simpson of Capital Wealth Planning supported the JPMorgan selection, calling it best-in-breed and highlighting a potential IPO market rebound as a catalyst. Arista's second-quarter revenue rose 38% year over year, with full-year guidance pointing to 40% annual growth. The company's AI Fabrics networking gear now serves over 100 customers. However, analysts note risks from customer concentration and potential AI spending slowdowns. Arista trades at a forward non-GAAP price-to-earnings ratio of 45.33, nearly double the sector median.
Brown Brothers Harriman's BBH Select Mid Cap ETF highlighted Arista Networks as a leading performance contributor in its Q2 2026 investor letter. The cloud networking solutions provider returned 38.4% during the quarter, driven by strong first-quarter results with record revenue and free cash flow. Arista reported 54% growth when including deferred product revenue, though guidance fell short of high expectations due to supply chain shortages and extended customer acceptance cycles for new AI products. The company maintained gross margin guidance of 62% to 64% despite rising component costs. Management expressed confidence in the 2026 outlook and expects to add one or two new customers representing over 10% of revenue beyond Microsoft and Meta. At quarter-end, Arista held an 85-hedge-fund following.
Arista Networks reported FY 2025 revenue of nearly $9.0 billion, up 28.6% year-over-year, with net income of roughly $3.5 billion and a 39% net margin. The company, which provides data centre networking equipment, carries no debt and generated close to $4.3 billion in free cash flow. However, two customers represented approximately 16% and 26% of annual revenue, creating concentration risk. International Business Machines posted FY 2025 revenue of nearly $67.5 billion, growing 7.6% year-over-year, with net income of close to $10.6 billion. The company's net margin improved to approximately 15.7% from 9.6% the previous year as it shifted toward higher-value software offerings. IBM provides software, consulting, and infrastructure services with partnerships including Amazon and Microsoft.
AppLovin and Arista Networks are both capitalising on AI-driven growth, but serve different markets. Arista Networks provides high-speed networking equipment for data centres, whilst AppLovin offers an AI-powered mobile app advertising platform. Arista Networks reported FY 2025 revenue of nearly $9.0 billion, up 28.6% year-over-year, with net income of approximately $3.5 billion and a 39% net margin. The company holds no debt and generated nearly $4.3 billion in free cash flow. However, two customers accounted for 16% and 26% of total revenue respectively, creating concentration risk. AppLovin achieved FY 2025 revenue of approximately $5.5 billion, representing 70% growth. Net income reached nearly $3.3 billion with a 60.8% net margin. The company completed the sale of its internal apps business in June 2025 to focus on its software and advertising platform.
Arista Networks shares have surged nearly 30% in three months, driven by AI-related demand and its first $3 billion quarter. One strategy offers investors a way to potentially buy the stock at a discount whilst earning income. By selling a put option on ANET expiring 17 June 2027 with a $115 strike price, investors can collect roughly $855 in premium per contract. This generates an 8.7% annualised return on the $11,500 cash secured for the trade. Combined with a 5.0% money market yield, the total return reaches approximately 13.7%. If ANET stays above $115, the put expires worthless and investors keep the premium. If it falls below $115, investors buy shares at an effective price of $106.45 after accounting for the premium — a 44% discount to today's $188.67 price. Arista recently raised its 2026 revenue forecast to $12.6 billion, projecting 40% annual growth.
