Cisco’s AI-fueled networking surge clears expectations—but margins slip

Beatpartly known
Non-GAAP EPS $1.22 vs approximately $1.17 consensus
CISCO SYSTEMS, INC. (CSCO) — AllSight decodes this SEC 8-K in plain English, versus what the market expected.

The quarter cleared a market bar already set above Cisco’s guidance. Published expectations were approximately $16.83 billion of revenue and $1.17 of non-GAAP EPS; Cisco delivered $17.252 billion and $1.22, respectively.

Networking is the real engine behind the beat. Product revenue rose 24%, with Networking up 28% to $9.791 billion, far outpacing Security at 14%, Collaboration at 12%, and Observability at 6%. The result supports the AI-infrastructure and campus-refresh narrative that was already emerging after Q3, but the magnitude of the networking acceleration is new. (Product revenue by market segment)

The earnings beat was not purely a margin story. Non-GAAP operating income increased 23% to $6.198 billion, but non-GAAP gross margin fell to 66.3% from 68.4% a year earlier, while product gross margin dropped to 64.8% from 67.5%. Cisco still exceeded its prior margin range, but the mix and cost pressure matter: more revenue is arriving, yet profitability per dollar is not expanding at the same pace. (Q4 non-GAAP results)

The initial FY2027 outlook extends the earnings step-up rather than merely confirming it. Cisco guided to $5.05–$5.11 of FY2027 non-GAAP EPS after producing $4.33 in FY2026, with Q1 revenue guided to $18.0–$18.2 billion and non-GAAP EPS to $1.32–$1.34. There is no established published consensus in the supplied context for the new full-year outlook, so this is best read as a substantial new earnings framework rather than a quantified beat. (Q1 FY2027 guidance; FY2027 guidance)

The net read is a genuine beat, with one important quality caveat. Revenue, adjusted EPS, FY2026 revenue, and FY2026 adjusted EPS all finished above the company’s prior ranges, and the new fiscal-year outlook points to continued growth. The offset is weaker non-GAAP gross margin and largely unchanged full-year operating cash flow, while inventories rose to $5.694 billion from $3.164 billion. The market knew demand was accelerating; this filing shows that acceleration translated into a larger-than-expected quarter, though execution now has to convert it into durable margins and cash.
