What happened
Cisco posted record fiscal 2026 revenue of $63.3 billion (up 12% year-over-year) and guided fiscal 2027 revenue growth of about 15% at the midpoint. CEO Chuck Robbins attributed the acceleration to "agentic AI" driving a "Networking Supercycle." AI infrastructure for hyperscalers generated about 6% of total revenue in fiscal 2026, up from less than 2% in fiscal 2025, and management expects that business alone to reach $7.5 billion in fiscal 2027—roughly a tenth of the guided $72.2 billion to $73.4 billion total. Despite the growth, shares fell 8.4% on Thursday.
Why it matters
The $7.5 billion AI revenue represents a fundamental shift in Cisco's business mix. However, the shift comes with a profit cost: non-GAAP gross margin fell 210 basis points year-over-year to 66.3% in the fourth quarter, with product gross margin down 270 basis points to 64.8%, driven by higher hardware mix and memory costs. AI infrastructure is physical equipment carrying lower margins than Cisco's software business, so even though earnings per share is guided to grow faster than revenue (about 17% at the midpoint), investors are concerned gross margin could keep declining as hardware sales grow.
What to watch
Management expects fiscal first-quarter gross margin of 65% to 66%—below the 66.3% just reported—signaling continued pressure ahead. Cisco booked $9.3 billion in hyperscaler AI infrastructure orders in fiscal 2026 and won three new hyperscaler design wins in the fourth quarter, suggesting the $7.5 billion guidance is grounded in real demand. The stock now trades at about 22 times forward earnings, down from about 24 times before the sell-off.

Cisco's growth acceleration is real and grounded in tangible order intake: the company booked $9.3 billion in hyperscaler AI infrastructure orders in fiscal 2026 and shipped enough that the business grew from less than 2% of revenue in fiscal 2025 to 6% in fiscal 2026. CEO Robbins' framing of a "Networking Supercycle" tied to agentic AI adoption reflects the strength of demand, evidenced also by the fact that total product orders rose 35% year-over-year in the fourth quarter and networking product orders grew 40% for the eighth consecutive quarter of double-digit growth.
The sell-off, however, reflects a real structural shift in Cisco's profit model. The AI infrastructure business is hardware-centric—fiscal 2026 orders ran roughly 60% Silicon One-based systems and 40% optics—and hardware carries substantially lower margins than software. Non-GAAP product gross margin fell 270 basis points to 64.8%, and management's first-quarter guidance of 65% to 66% signals this erosion is not temporary. While earnings per share is still guided to grow about 17% at the midpoint (faster than revenue), that outperformance depends on operating cost discipline; gross margin itself appears structurally pressured as the hardware mix grows.
At roughly 22 times forward earnings, the stock is pricing in modest further margin decline. If hardware becomes an even larger slice of the revenue mix—as the $7.5 billion guidance suggests it will—investors may need to reassess whether Cisco's forward multiple is sustainable.
