Shares of Arista Networks (ANET) experienced a significant rally of 8.2% on March 4, 2026, following a compelling presentation by company leadership at the Morgan Stanley Technology, Media & Telecom Conference the previous day.
The shares ended trading at $134.83 after the March 3 investor presentation.
The most significant catalyst driving the stock higher was Arista’s dramatic TAM expansion. The networking equipment provider increased its Total Addressable Market projection to $105 billion from its previous estimate of $60 billion—nearly doubling the company’s addressable opportunity.
Company leadership also stood by its previously announced 2026 AI networking revenue target of $3.25 billion. This figure is anticipated to account for approximately 30% of overall revenue.
Total annual revenue is projected to exceed $10 billion, marking an increase from the $9 billion recorded in the previous fiscal year. Management also indicated that as many as four customers might individually represent more than 10% of total revenue during the current year.
Beyond the financial projections, Arista detailed its technical approach to AI networking infrastructure. The company showcased its all-Ethernet AI spine and leaf architecture, with its 7800 AI Spine product—operating at 800 gigabits—serving as the cornerstone for scale-across implementations.
The networking specialist is collaborating with data center operators on three distinct deployment strategies: scale-up, scale-out, and scale-across configurations.
Wall Street Response
The stock’s upward movement came after Piper Sandler upgraded its price objective on February 13. The investment firm lifted its target price to $175 from $159 while reiterating its Overweight stance following Arista’s strong quarterly performance that exceeded Wall Street estimates.
Quarterly revenue reached $2.49 billion, surpassing the consensus estimate of $2.38 billion. Earnings per share hit $0.82, beating the anticipated $0.76.
Piper Sandler additionally highlighted Arista’s updated annual growth estimate of 25%, representing a five-percentage-point increase from its earlier guidance.
Operational Challenges
During the conference, Arista management identified a persistent supply chain headwind: a memory shortage impacting its customer base. Company executives estimated a two-year timeline for resolution and noted that Arista is making strategic investments in chips, silicon, and memory components to mitigate the constraint.
This supply chain limitation warrants close monitoring, especially given the accelerating demand for AI infrastructure among enterprise customers.
From a technical perspective, ANET currently trades above both its 50-day and 200-day moving averages. Immediate resistance is located at $137.15. The 52-week low stands at $59.43, meaning the current price represents approximately 127% appreciation from that bottom.
The stock is trading roughly 18% below its 52-week peak of $164.94.
Piper Sandler’s $175 price target implies approximately 30% upside potential from the March 4 closing price.
