Why It’s Moving
Arista Networks Shares Volatile as Blowout Q3 Earnings Clash with Sector-Wide AI Retreat
- Q3 results exceeded expectations with $1.20 EPS versus the $1.08 consensus and $3.66 billion in revenue, marking a 58.5% year-over-year increase that CEO Jayshree Ullal highlighted as historic for the company.
- Management raised its 2027 outlook to target $18.5 billion in total revenue, including a projected doubling of the AI fabric business to $7 billion, signaling sustained long-term demand despite near-term volatility.
- Despite the earnings beat, shares tumbled 10% amid a sector-wide retreat triggered by analyst downgrades on peers like Cisco and Ciena, while also falling 21.2% over the past month due to rich valuation premiums and customer concentration worries.
ServiceNow Shares Swing on AI Momentum and Margin Pressures
- Management increased the fiscal year AI annual contract value (ACV) target to $1.7 billion as adoption accelerates, with net new AI ACV growing 65% year-over-year.
- Gross margins are under pressure, declining from 86% in 2022 to an expected 81% in 2026 due to higher delivery costs and partner expenses associated with driving AI adoption.
- The company expanded strategic partnerships, including a joint go-to-market initiative with LTM to scale agentic AI and a deployment of EmployeeWorks by the NBA to enhance internal workflows.
