Arista Networks (ANET) surged 17.49% on August 6, 2025, with a trading volume of $3.58 billion, a 101.63% increase from the prior day, ranking 16th in the market. The rally followed the company’s second-quarter earnings report, which exceeded revenue and profit expectations, driven by 30.4% year-over-year revenue growth to $2.21 billion and a 38% rise in adjusted EPS to $0.73. Analysts from Morgan Stanley, UBS, and Goldman Sachs raised price targets, reflecting optimism about Arista’s guidance and AI/cloud-driven demand. Management highlighted a $1 billion non-GAAP operating income milestone and a 2025 revenue growth target of 25%, including AI-related sales of $1.5 billion.

Strong gross margin expansion to 65.2% and robust demand from cloud infrastructure fueled the performance. Analysts noted Arista’s position in AI networking, with visibility into customer capital spending and deferred revenue growth. While concerns about back-end AI market share and competition persist, the stock’s technical indicators, including a high composite rating, underscore near-term momentum. The company plans an investor day on September 11 to outline strategic priorities.
