It has underperformed its peers like Hewlett Packard Enterprise Company (HPE - Free Report) but outperformed Cisco Systems, Inc. (CSCO - Free Report) . HPE has gained 153.6%, and Cisco has increased 35.7% during this period.
Solid AI Momentum, Growing Customer Base are Positives
Arista Networks is benefiting from the rapid expansion of AI infrastructure. Cloud providers and hyperscalers are investing heavily in networking capacity to support growing compute workloads. Backed by these factors, Arista disclosed that its AI fabrics business has expanded to more than 100 cumulative customers compared with only four to five customers in 2024. Management also expects AI revenues to reach at least $3.6 billion in 2026, supported by scale-up, scale-out and scale-across deployments.
Organizations are increasingly preferring an integrated hardware-and-software approach as complex AI deployments require reliability, simplicity and specialized networking features. This shift toward integrated networking is beneficial for Arista’s EOS platform, which is closely integrated with switching hardware solutions.This positions Arista favorably against major networking rivals such as Cisco and HPE.
The transition toward higher-speed networking is another long-term catalyst. Arista has introduced the 7060XE7 with 100-terabit capacity and 1.6-terabit throughput, along with liquid-cooling options designed for next-generation AI infrastructure. Management expects 1.6T products to enter customer trials in the second half of 2026. Production is expected to ramp in 2027.
Improvement in Supply Chain and Strong Cash Flow Growth are Tailwinds
The company has expanded supplier qualification, secured additional component sources and strengthened strategic supplier relationships. It has also secured memory supply for 2026. In previous quarters, supply constraints restricted Arista’s ability to fully address demand. Its proactive approach to resolving those issues will increase its ability to convert higher demand into higher shipments.
Arista’s strong liquidity and cash generation provide financial flexibility to support continued AI networking investment. During the first six months of 2026, operating cash flow increased to $2.78 billion from $1.84 billion in the same period of 2025. As of June 30, 2026, cash and cash equivalents stood at $2.3 billion, while marketable securities totaled $11.1 billion. This financial capacity supports continued investment in product development, manufacturing expansion and working capital as AI networking deployments scale.
Estimate Revision Trend
Earnings estimates for Arista for 2026 and 2027 have increased over the past 60 days.
