Cisco Systems (NASDAQ: CSCO) delivered a Q4 that was strong by any measure. The numbers that matter most for the next 12 months point to a structural shift in demand, not just a cyclical bounce. Revenue of $17.3 billion beat the consensus estimate of $16.8 billion by roughly 3% and rose 18% year over year, while non-GAAP EPS of $1.22 topped the $1.17 estimate by about 4.5%. Both landed above the high end of Cisco's own guidance range.
The headline numbers are impressive. The composition of the beat is what separates this quarter from a garden-variety upside surprise. Product revenue grew 24% year over year to $13.5 billion, driven by a 28% jump in Networking. That segment alone contributed $9.8 billion in Q4 revenue. Security rose 14%, Collaboration 12%, and Observability 6%. Services revenue was flat at $3.8 billion, typical for a mature installed-base business but underscoring that the growth story is entirely product-led.
The real engine is the AI infrastructure buildout. Cisco took $4 billion in AI-related orders from hyperscalers during Q4, bringing the fiscal year total to $9.3 billion. That's not just a pipeline number; the company delivered roughly $4 billion of AI revenue in FY2026 and expects $7.5 billion in FY2027. The implied 88% year-over-year growth in AI revenue is the single most important data point in this release. It suggests that Cisco's networking gear is becoming a structural beneficiary of hyperscaler capex cycles, not a peripheral supplier.
Total product orders rose 35% year over year in Q4, marking the eighth consecutive quarter of double-digit growth. Excluding hyperscalers, orders were still up 25%, with double-digit growth across every geography and customer market. That breadth matters. The demand isn't concentrated in a handful of mega-accounts; it's broad-based, spanning enterprise, service provider, and public sector. Americas revenue grew 18%, EMEA 19%, and APJC 14%. The geographic uniformity reinforces the case that this is a networking supercycle, not a one-off.
Non-GAAP gross margin came in at 66.3%, down 210 basis points from 68.4% a year ago. That compression is worth watching. Product gross margin on a non-GAAP basis fell to 64.8% from 67.5%, a 270bp decline. The company attributed this to product mix, with higher volumes of lower-margin networking gear and AI infrastructure diluting the blended rate. This is a structural dynamic, not a cyclical one. As AI revenue scales, gross margin may face continued pressure, but the absolute dollar contribution more than compensates. Non-GAAP operating margin of 35.9% was up 160bp from 34.3% a year ago, driven by operating leverage. Operating expenses grew only 5% on a non-GAAP basis, well below revenue growth.
Cisco's guidance for FY2027 is the strongest signal yet that management sees this momentum as durable. Revenue is expected at $72.2 billion to $73.4 billion, implying 14% to 16% growth from FY2026's $63.3 billion. Non-GAAP EPS guidance of $5.05 to $5.11 represents 17% to 18% growth from $4.33. Q1 FY2027 revenue guidance of $18.0 billion to $18.2 billion implies sequential growth of about 4% to 5% from Q4, above typical seasonal patterns. The non-GAAP gross margin guidance of 65% to 66% for Q1 suggests management expects the mix-driven compression to persist.
The capital allocation story remains consistent. Cisco returned $3.2 billion to shareholders in Q4 through $1.5 billion in buybacks and $1.7 billion in dividends. The quarterly dividend was maintained at $0.42. With $15.9 billion in cash and investments and $8.1 billion remaining in the buyback authorization, the balance sheet provides ample room for both organic investment and M&A. The acquisitions of Galileo Technologies (observability) and Astrix Securities (non-human identity security) closed during the quarter, signaling continued bolt-on activity in adjacent markets.
What to watch next: the sustainability of the 40% networking order growth rate. Eight consecutive quarters of double-digit growth is a long run, and comps get harder from here. The AI revenue ramp to $7.5 billion in FY2027 is the key variable. If hyperscaler capex holds, Cisco's networking business could see a multi-year tailwind. If it moderates, the gross margin pressure becomes a more prominent concern. For now, the company is executing at a level that justifies the premium valuation, but the margin trajectory will determine whether that premium holds.
