Cisco Systems (CSCO) & Arista Networks (ANET): Cisco Just Beat Every Estimate. Why Did the Stock Still Drop 8%?
Cisco (CSCO) reported Q4 earnings and revenue beating estimates, with revenue up 18% YoY to $17.25B and net income up 51% to $3.9B. Despite strong results, shares dropped 8.4%. Arista (ANET) also beat estimates with Q2 revenue up 37.7% YoY to $3.036B, and its stock did not decline. Cisco's guidance was above expectations, but some analysts worry about growth peaking. Arista's growth is driven by hyperscaler and AI customers, similar to Cisco's concentration risk.
