Arista Networks 2025 Q3 Earnings Strong Revenue and Net Income Growth Beats Estimates

Arista Networks (ANET) reported Q3 2025 results that exceeded expectations, with revenue rising 27.5% year-over-year to $2.31 billion and EPS increasing 15.3% to $0.68. The company maintained its profitability streak for 13 consecutive years and provided Q4 guidance in line with market forecasts.

Revenue

Arista Networks' total revenue surged to $2.31 billion in Q3 2025, driven by robust demand in data center and cloud infrastructure. Product revenue accounted for the lion’s share at $1.91 billion, reflecting strong sales of Ethernet switches and software. Service revenue added $396.60 million, underscoring the company’s recurring revenue model. The 27.5% year-over-year growth highlights ANET’s market leadership in high-speed networking solutions.

Earnings/Net Income

The company’s earnings per share (EPS) rose to $0.68, a 15.3% increase from $0.59 in the prior-year quarter, while net income grew 14% to $853 million. These results reflect disciplined cost management and operational efficiency, with the company sustaining profitability for 13 years. The EPS performance is positive, aligning with its strategic focus on AI and cloud infrastructure.

Post-Earnings Price Action Review

Arista Networks’ stock experienced mixed post-earnings performance, with a 0.45% gain on the day of the report but a 10% decline in after-hours trading despite beating revenue and EPS estimates. The "Buy on Revenue Beat, Hold for 30 Days" strategy showed historical consistency, with an average return of ~4.5% across four quarters. However, short-term volatility, such as the Q3 2025 post-earnings drop, underscores risks in relying solely on revenue beats for timing. The backtesting period (2023–2025) is limited, and market conditions—particularly in AI and cloud infrastructure—remain subject to rapid shifts.

CEO Commentary

CEO Jayshree Ullal emphasized ANET’s “centers of data strategy,” which drove 4.7% quarter-over-quarter revenue growth. She highlighted strategic hires, including CTO Kenneth Duda and SVP Tyson Lamoreaux, as part of Arista’s innovation push in AI and cloud networking. The CEO’s optimism aligns with the company’s focus on open standards and market expansion.

Guidance

Arista Networks projected Q4 2025 revenue of $2.3–$2.4 billion, with non-GAAP gross margins of 62–63% and operating margins of 47–48%. The guidance excludes stock-based compensation and other non-recurring items, reflecting disciplined execution. CFO Chantelle Breithaupt attributed the 25% non-GAAP EPS growth to strategic roadmap execution and margin preservation.
