Material Changes vs. Prior Period

• Revenue Growth: Total revenue increased 30.4% year-over-year (YoY) for Q2 and 29.1% YoY for the six months ended June 30, 2025. Product revenue grew 31.9% in Q2, driven by increased demand for switching and routing platforms.
• Margin Expansion: Gross margin improved to 65.2% in Q2 2025 from 64.9% in Q2 2024, attributed to improved inventory management and lower excess/obsolescence charges.
• Acquisition: On June 30, 2025, Arista completed the acquisition of the VeloCloud business from Broadcom for $300.0 million in cash. This adds AI-optimized cloud WAN capabilities to Arista's portfolio.
• Stock Repurchases: The company completed its prior $1.2 billion repurchase program in May 2025 and authorized a new $1.5 billion program. In Q2 2025, the company repurchased $195.9 million of common stock.

Guidance, Outlook, and Risks

Management Commentary: Management highlights strong demand for AI networking solutions, which are data and compute-intensive. The company is investing heavily in R&D to support AI Ethernet products and the Arista Autonomous Virtual Assist (AVA). The acquisition of VeloCloud is expected to complement the data center and campus portfolio with modern WAN solutions.

Risks and Contingencies:

• Customer Concentration: Revenue remains heavily dependent on a limited number of large customers (e.g., Microsoft, Meta). Variability in their capital expenditure cycles and AI deployment timelines creates revenue volatility.
• Trade and Tariffs: Escalating U.S. tariffs and trade tensions, particularly with China, pose risks to supply chain costs and gross margins. The company is actively monitoring these impacts.
• Supply Chain: Reliance on sole or limited sources for key components (e.g., merchant silicon from Broadcom) creates risks of shortages or price increases.
• Legal Proceedings: Ongoing litigation with WSOU Investments LLC regarding patent infringement remains stayed pending further proceedings, though the Federal Circuit recently affirmed a PTAB ruling in Arista's favor regarding one patent.
• Tax Legislation: The "One Big Beautiful Bill Act" (OBBB Act) signed on July 4, 2025, may impact future effective tax rates, though the full effect is currently being evaluated.

Investor Verification Checklist

• Deferred Revenue Quality: Verify the composition of the $4.06 billion deferred revenue balance, specifically the portion related to contracts with acceptance clauses, which introduces revenue recognition timing risk.
• Inventory Levels: Monitor inventory balances ($2,059.1M) against sales velocity to assess potential for future write-downs given the volatility in AI demand forecasts.
• Customer Concentration: Review specific revenue contributions from top customers (Microsoft, Meta) in upcoming filings to gauge dependency risks.
• Tariff Impact: Assess the actual impact of new reciprocal tariffs and trade policies on the cost of revenue and gross margins in subsequent quarters.
• Acquisition Integration: Track the integration progress and financial contribution of the VeloCloud acquisition in future reports.
