The company's product revenue, which primarily consists of sales from its switching and routing platforms, rose by 28.8% to $7.6 billion, while service revenue increased by 27.7% to $1.4 billion. The gross profit for the year was $5.8 billion, maintaining a gross margin of 64.1%, consistent with the previous year. This performance reflects strong customer demand and higher shipments across its product lines.
Compared to the previous fiscal year, Arista's revenue growth was bolstered by a diverse customer base, with notable contributions from its Cloud and AI Titans, which accounted for approximately 48% of total revenue. The company also saw a geographic expansion, with non-Americas revenue increasing from 18.2% in 2024 to 20.9% in 2025, driven by a shift in the sales mix to global customers. The total number of customers increased, and the company reported a growing installed base, which contributed to the rise in service revenue.
Strategically, Arista completed the acquisition of VeloCloud for $300 million in June 2025, enhancing its portfolio in the AI-optimized cloud WAN space. This acquisition aligns with Arista's focus on expanding its capabilities in AI and cloud networking. The company continues to invest in research and development, with R&D expenses increasing by 24.1% to $1.2 billion, reflecting its commitment to innovation and product development.
Operationally, Arista's employee headcount grew to approximately 5,115 as of December 31, 2025, supporting its expansion efforts. The company reported a total of $6.8 billion in non-cancellable purchase commitments, indicating a proactive approach to managing supply chain challenges and ensuring product availability. Despite the positive financial results, Arista acknowledged potential risks, including supply chain disruptions and geopolitical tensions, which could impact future performance.
Looking ahead, Arista anticipates continued revenue growth driven by the increasing demand for AI-enabled solutions and the expansion of its product offerings. The company remains focused on maintaining its leadership position in the networking industry while navigating the evolving market landscape.
