Summary
Arista Networks co-founder Andreas Bechtolsheim has cumulatively sold about $668 million worth of stock since May through 14 prearranged transactions under a 10b5-1 plan, leaving roughly 14% of Arista held by his family trust and about 2% of his stake sold. The sales come as the company posted its strongest YoY revenue growth in public-company history, but a lofty 67x earnings multiple keeps valuation risk in focus. The pattern appears to be routine diversification rather than a signal about the stock’s prospects, with timing dictated by the pre-set plan rather than market moves. Investors will watch the next Form 4 for any deviation from the plan or acceleration in selling, which could alter sentiment. Forward, Arista reiterated strong growth expectations and a 2027 revenue target, highlighting ongoing questions about multiple expansion versus execution.
