Arista Networks CEO and Chairperson Jayshree Ullal sold 52,838 shares in the open market on April 22, 2026, at $177.28 per share, for a total value of about $9.37 million. As the company’s top executive and board chair, Ullal is among the insiders most closely watched by investors because she has deep visibility into Arista’s operations and long-term strategy, even though insider sales can happen for many personal reasons. This sale stands out not just for its size, but because it continues a clear run of selling activity by Ullal during April. In the prior week alone, she sold about $7.30 million on April 16, about $7.68 million on April 20, and another roughly $757,570 on April 21, culminating in the April 22 transaction. That cluster suggests a deliberate reduction in her holdings over a short period rather than a one-off sale. Other recent insider activity has been more limited: director Kenneth Duda sold about $213,400 on April 17. With multiple large sales concentrated in a single month and led by the CEO/Chair, investors may view this period as notable for insider selling intensity at ANET.
