Shares of Arista Networks (ANET) experienced an 8.2% gain on March 4, 2026, driven by management’s presentation of an expanded market opportunity during the Morgan Stanley Technology, Media & Telecom Conference held the previous day.
The stock finished trading at $134.83 after the March 3 investor presentation.
The most significant announcement that energized investors was the TAM update. The company expanded its Total Addressable Market projection to $105 billion from a previous estimate of $60 billion. This represents nearly a 75% increase in the company’s addressable opportunity.
The firm also stood by its 2026 AI networking revenue projection of $3.25 billion. This amount accounts for approximately 30% of anticipated total revenue.
Overall revenue for the full year is projected to exceed $10 billion, marking an increase from last year’s $9 billion. Management indicated the possibility of having four customers each representing more than 10% of overall revenue during the current year.
Beyond the financial metrics, Arista detailed its AI network infrastructure strategy, featuring an all-Ethernet AI spine and leaf architecture. The company’s primary AI Spine offering, the 7800, delivers 800 gigabit performance and serves as a cornerstone for scale-across implementations.
The firm is collaborating with data center operators on three distinct deployment approaches: scale-up, scale-out, and scale-across configurations.
Wall Street Response
The stock rally came after Piper Sandler upgraded its price objective on February 13. The investment firm elevated its target to $175 from $159 and retained its Overweight stance following Arista’s most recent quarterly performance that exceeded analyst projections.
Quarterly revenue reached $2.49 billion, surpassing the $2.38 billion consensus estimate. The company reported earnings per share of $0.82, beating the anticipated $0.76.
Piper Sandler also highlighted Arista’s updated annual growth forecast of 25%, representing a five-percentage-point increase from the company’s earlier projection.
Supply Chain Considerations
During the conference, Arista identified a persistent challenge: a memory shortage impacting its client base. Management estimated a two-year timeframe for resolving this constraint and noted the company’s investments in chips, silicon, and memory components to mitigate the bottleneck.
This supply limitation warrants close attention, especially as customer appetite for AI infrastructure continues its upward trajectory.
From a technical perspective, ANET currently trades above both its 50-day and 200-day moving averages. The immediate resistance level is positioned at $137.15. With a 52-week low of $59.43, the current price stands approximately 127% higher than that threshold.
The stock trades roughly 18% below its 52-week peak of $164.94.
Piper Sandler’s $175 price objective suggests approximately 30% potential upside based on the March 4 closing price.
