Cisco Systems Inc

Strong Q3 results beat guidance (good): - Record Q3 revenue: $15.8B (+12% YoY); non-GAAP EPS: $1.06 (+10% YoY), both above the high end of guidance. - Product revenue: $12.1B (+17% YoY); services revenue: $3.7B (-1% YoY) (mainly timing of service contract starts). - Non-GAAP gross margin: 66% (-260 bps YoY); margin pressure mainly from mix + higher memory costs, partially offset by productivity. - Non-GAAP operating margin: 34.2%, tax rate ~19%.

Demand surge led by AI infrastructure + networking (good/surprising): - Total product orders +35% YoY; excluding hyperscalers +19% (suggests demand is not purely hyperscaler-driven). - AI infrastructure orders from hyperscalers: $1.9B in Q3 vs $0.6B prior year; total FY26 hyperscaler orders to date: $5.3B already above prior expectation of $5B with a full quarter left. - Cisco now expects ~$9B AI infrastructure orders in FY26 (from hyperscalers), ~4.5x FY25, and expects to recognize ~$4B AI infrastructure revenue from hyperscalers in FY26. - Additional AI infrastructure orders (non-hyperscaler): ~$300M in Q3; ~$900M YTD, with a growing ~$3B pipeline. - Networking momentum: networking product orders >50% YoY, with 7th consecutive quarter of double-digit networking growth; campus wireless orders >40% YoY, WiFi 7 orders ~half the mix in Q3.

AI optics business accelerating sharply; “Silicon One” differentiation (opportunity/good): - Acacia coherent pluggable optics: > $1B orders in Q3, on track for >200% YoY growth in FY26; also shipped 750k+ 400G and 40k+ 800G coherent pluggable optics. - Hyperscaler design wins: 5 new design wins in Q3 (2 optics, 3 systems). For systems, Cisco highlighted early adoption of Silicon One P200-powered and G200-powered systems. - Management implication: Silicon One is a key reason hyperscalers select Cisco (more supply-chain control + silicon dependency by hyperscalers).
