Super Micro Computer and Arista Networks reported quarterly results above analyst expectations, underscoring continued demand for the servers and networking equipment used to build artificial intelligence data centers. Both companies also issued current-quarter forecasts that exceeded Wall Street estimates.
The results arrive as investors weigh the scale and durability of spending on AI infrastructure. Supermicro supplies servers and storage systems, while Arista provides networking equipment that connects large clusters of graphics processing units and other high-performance chips. Their products are components of the physical systems on which AI workloads run, including systems that enterprises may operate alongside existing data center and cloud environments.
Supermicro sales rise 298%
For its fiscal 2027 first quarter, Supermicro reported earnings of $1.81 per share before certain costs, including stock-based compensation, and revenue of $19.95 billion. Analysts had expected earnings of $1.23 per share and revenue of $17.35 billion. Revenue increased 298% from the year-earlier quarter.
The company’s gross margin was 12.8%, compared with 9.3% in the same quarter a year earlier. The improvement is notable amid investor concerns about higher component costs and potential supply constraints, although the reported figures alone do not establish how those factors may affect future results.
Chief Executive Charles Liang said Supermicro was selling its servers and storage solutions as quickly as it could build them. He also described the company’s shift toward providing broader AI and IT data center solutions as accelerating.
For fiscal second quarter, Supermicro forecast earnings between $1.66 and $1.90 per share and revenue between $19.5 billion and $21.5 billion. The company’s sales outlook was above the analyst forecast of $18.1 billion, while its earnings range was also higher than the expected $1.14 per share.
Arista revenue grows 58%
Arista reported third-quarter earnings of $1.20 per share on revenue of $3.66 billion. Revenue was up 58% year over year. Analysts had forecast earnings of $1.08 per share and revenue of $3.33 billion. The company’s revenue growth was its largest year-over-year increase since it went public in 2014, according to the reported results.
Arista forecast fourth-quarter earnings of $1.26 to $1.30 per share and revenue of $3.95 billion at the midpoint of its range. That revenue midpoint would represent growth of 59%, based on the company’s outlook. Analysts had expected $1.16 per share in earnings and $3.65 billion in revenue.
Chair and Chief Executive Jayshree Ullal said the company’s results had exceeded her expectations. She attributed the momentum across customer sectors to Arista’s growing relevance in the generative and agentic AI era.
Infrastructure suppliers in focus
The two companies serve different parts of the data center buildout. Supermicro’s systems provide compute and storage capacity, while Arista’s networking products link equipment into large clusters. Together, those layers help determine how organizations can deploy and connect the hardware required for AI workloads.
The earnings reports and forecasts indicate that demand was strong enough in the reported periods to drive substantial growth at both suppliers. They do not, by themselves, establish how long that pace will continue. The companies’ next results will provide further information on whether their current projections translate into sustained sales and profitability.
