On May 19, Arista Networks fell 3.21% in regular trading, trading at approximately $137.70/share, with trading volume of $291 million, erasing gains from its prior consecutive rebound sessions.
The decline was driven by broad-based selling across the communication equipment sector, with Applied Optoelectronics down 4.76%, Ciena down 3.08%, Nokia down 3.06%, Cisco down 2.99%, and Lumentum down 2.87%, reflecting pronounced sector-wide pressure.
On the fundamental side, while Arista reported strong Q1 results with revenue of $2.71 billion (up 35.1% YoY) and adjusted EPS of $0.87 beating expectations, the company's Q2 adjusted operating margin and gross margin guidance fell short of market expectations. Management explicitly warned that shortages across wafers, chips, and memory components will persist for one to two years, constraining delivery capacity despite robust demand. The fabless business model's heavy reliance on external manufacturing has amplified concerns about order fulfillment during this supply-constrained environment, continuing to weigh on valuation.
