Earnings Whispers
Our proven model does not conclusively predict an earnings beat for Arista for the third quarter. The combination of a positive Earnings ESP and a Zacks Rank #1 (Strong Buy), 2 (Buy) or 3 (Hold) increases the chances of an earnings beat. This is not the case here. You can uncover the best stocks to buy or sell before they’re reported with our Earnings ESP Filter.
AI infrastructure remains a key growth driver for Arista. Its Etherlink portfolio has surpassed 100 cumulative AI fabric customers. The introduction of its 7060XE7 Series has extended Arista’s offerings into next-generation 1.6-terabit networking. These platforms are designed to support increasingly demanding AI workloads through high-bandwidth connectivity and advanced cooling options. Continued adoption of Ethernet-based AI infrastructure and expansion across scale-up, scale-out and scale-across deployments could support revenue growth in the September quarter.
During the quarter, Arista introduced AI-Driven Zero Trust Branch, integrating AI-powered security, identity-based access, and cloud-managed networking into a unified platform. The solution enhances branch protection, simplifies policy enforcement, improves operational efficiency, and enables secure, scalable connectivity for distributed enterprises and hybrid work environments. Such innovative product launches are expected to have a favorable impact on third-quarter results.
Arista's broader networking portfolio may provide additional support. Its software-driven Extensible Operating System, CloudVision platform and enterprise campus networking offerings help address requirements beyond hyperscale data centers. Growth in its installed customer base also supports demand for maintenance, support and other services.
Price Performance
Over the past year, Arista shares have gained 19.3% against the industry’s decline of 10.5%, lagging peers like Hewlett Packard Enterprise (HPE - Free Report) and Cisco Systems, Inc. (CSCO - Free Report) . Cisco has gained 54.2%, while Hewlett Packard has soared 150.9% during this period.

Key Valuation Metric
From a valuation standpoint, Arista appears to be trading at a premium compared with the industry and above its mean. Going by the price/earnings ratio, the company's shares currently trade at 37.83 forward earnings, higher than 28.67 for the industry and lower than the stock’s mean of 45.

Investment Consideration
Arista's growth outlook remains supported by expanding AI infrastructure investment, demand for high-speed Ethernet networking and continued product innovation. Supply chain execution is another important aspect. Management reported progress in supplier diversification, component availability and manufacturing capacity, but industry-wide component tightness and higher procurement costs persist. Arista's multiyear purchase commitments reached approximately $9.7 billion by the end of the second quarter, reflecting efforts to secure components and meet expected demand.
Based on our proprietary calculation, trailing 12-month return on invested capital (ROIC) is 27.1%, above Arista’s 10-year median of 23.9% and the 12.6% industry median; the 3-year median of 27.1% also shows that returns have remained elevated recently. ROIC helps investors assess whether growth is being generated with productive use of committed capital. Arista’s software-driven architecture, strong operating profitability and asset-light outsourced manufacturing model support attractive capital efficiency.
End Note
Arista enters the third quarter of 2026 with strong AI networking momentum and a growing product portfolio. A strong focus on innovation, broader enterprise adoption and supply chain improvements are major tailwinds. Upward estimate revision reflects growing investors’ confidence in the stock’s growth potential. With a Zacks Rank #2 and strong price performance, Arista appears to be a good investment option at present.
