Cisco Q4 Earnings Preview: AI Orders May Beat Expectations Again, Security Business Becomes Key Validation Point
Claire Weston
Cisco reports Q4 earnings on August 12. Wall Street expects revenue of $16.85 billion, up 14.9% year-on-year; the real question is whether AI infrastructure order guidance gets raised a third time — and whether the security segment can deliver on its 'near-double-digit growth' promise.
What number does the market care about most?
Wall Street expects Q4 revenue of $16.85 billion, up 14.9% YoY, with adjusted EPS of $1.17, up 18.2%.
The real suspense is not Q4 itself — it is whether AI order guidance gets raised again. Last time, Cisco lifted it from $5 billion to ~$9 billion, and the stock surged nearly 17% after hours.
This means → the market treats "guidance raise" as the metronome of Cisco's AI story. Whether it happens — and by how much — matters more than the quarterly print.
Why is the networking segment carrying the heaviest load?
Analysts expect Q4 networking revenue of $9.7 billion, up 27.1% YoY — the fastest-growing segment, driven by AI data-center switching and routing.
UBS, in an August 4 note, is even more bullish: networking revenue could top its $9.6 billion forecast, product orders may grow ~29% YoY, and EPS could reach $1.19, above consensus.
In plain terms = hyperscale cloud operators — Google, Amazon, Microsoft — are building AI data centers at breakneck speed. Cisco's switches and routers are the nervous system of those data centers, so orders follow.
Why are Citi and UBS so far apart?
UBS expects Q4 revenue and earnings to both beat, citing three consecutive months of strengthening AI infrastructure demand.
Citi raised its price target from $112 to $139, yet its Q4 revenue estimate is just $14.6 billion — $2.2 billion below consensus — with EPS at $0.98, also well below.
This reflects a split over the campus equipment refresh cycle. Citi explicitly warned that Wall Street's expectations for campus upgrades "appear somewhat elevated."
Why does FY2027 AI revenue guidance matter more than Q4?
CFO Mark Patterson called it "reasonable" for FY2027 AI revenue from hyperscale customers to reach at least $6 billion, up 50% from the $4 billion expected in FY2026.
UBS projects FY2027 revenue guidance of $68–69 billion, powered by more than $2 billion in incremental AI revenue.
Morningstar goes further: FY2027 AI revenue could hit $8 billion, well above management's $6 billion floor. This means → Morningstar is betting Cisco's pattern of "guide low, raise quarterly" will repeat.
Security — the overlooked fundamental variable?
Splunk, acquired in 2024 for roughly $28 billion, is seeing customers shift from upfront license deals to ratable cloud subscriptions — in plain terms = switching from "buy once" to "pay monthly" — which depresses near-term revenue during the transition.
Analysts expect Q4 security revenue of $2.04 billion, up just 4.7% YoY, the weakest segment.
CEO Chuck Robbins gave an unusually specific timeline in May: organic security should reach "near-double-digit revenue growth" by the end of this fiscal year, with comparisons "more normalized" by FY2027 Q2. This means → August 12 is the first hard checkpoint to see whether that promise turns from words into numbers.
What other risks should investors watch?
Gross margin: UBS expects rising component costs to cap Q4 gross margin expansion at roughly 66%.
Tariffs: CFO Patterson said guidance assumes current tariff policy holds through the end of 2026 — any change is an open variable.
Restructuring: Cisco announced in May it would cut nearly 4,000 jobs (under 5% of headcount) to redirect investment toward AI and related growth areas.
Put simply = whether AI order guidance gets raised a third time + whether security delivers on its promise — these two threads together determine if the market reprices Cisco's AI-transformation narrative into its next phase.
