Cisco delivered record Q4 revenue of $17.3 billion, up 18%, and finished fiscal 2026 with $9.3 billion in hyperscaler AI orders, yet the rally stalled after its August 12 earnings. Demand was not the problem.
After gaining about 61% in 2026, Cisco now has to prove that its rapidly growing AI infrastructure business can generate enough profit to justify its valuation.
Product orders rose 35% and networking orders 40%, confirming the breadth behind Cisco’s record quarter.
Cisco booked $9.3B of FY2026 hyperscaler AI orders but recognized only about $4B of related revenue, making order conversion one of the biggest tests for FY2027. Related hyperscaler AI infrastructure revenue is expected to reach $7.5B.
Adjusted gross margin fell from 68.4% to 66.3%, with Q1 guidance at 65% to 66% as hardware captures more of Cisco’s growth.
Adjusted operating margin still reached 35.9%, showing that lower gross margins have not yet weakened overall profitability.
Revenue, adjusted EPS and fiscal 2027 guidance all cleared pre-report expectations. The problem was not the quarter. It was the price already attached to Cisco’s future growth.
At the $123.88 regular-session close, the midpoint of fiscal 2027 adjusted EPS guidance of $5.08 implied roughly 24.4 times forward adjusted earnings. The roughly 4% after-hours decline was modest beside Cisco’s 2026 advance, making the move more useful as an expectations signal than evidence of a broken growth story.
The earnings beat was large. The expectations embedded in that rally were larger.
Strong revenue alone was no longer enough at that valuation. Cisco also had to show that its AI-driven growth could produce enough profit to support the price already being paid for it, and falling gross margins left that question open.
Cisco booked $4 billion of hyperscaler AI infrastructure orders in Q4 alone, lifting fiscal 2026 orders to $9.3 billion. Related revenue was only about $4 billion for the full year, although Cisco expects it to reach $7.5 billion in fiscal 2027.
Cisco’s total revenue would rise by about $9.5 billion at the midpoint of its fiscal 2027 guidance. The expected $3.5 billion increase in hyperscaler AI infrastructure revenue implies that AI could account for roughly 37% of Cisco’s incremental fiscal 2027 revenue growth.
At $7.5 billion, hyperscaler AI infrastructure would represent about 10% of total fiscal 2027 revenue at the guidance midpoint. AI is becoming large enough to shape Cisco’s profitability, not merely lift its growth rate.
Product revenue jumped 24% in Q4 while services revenue was essentially flat, with networking revenue rising 28% to $9.79 billion. That increasingly hardware-heavy mix, alongside higher memory costs, pushed adjusted gross margin down from 68.4% to 66.3%, while product gross margin fell from 67.5% to 64.8%. Cisco is guiding Q1 fiscal 2027 gross margin lower again at 65% to 66%.
Operating profitability has not followed it down. Adjusted operating margin reached 35.9% in Q4 and is guided to 35.5% to 36.5% next quarter. Operating expenses rose only 5% while revenue increased 18%, helping adjusted operating income grow 23%.
For now, weaker product margins have not translated into weaker operating profitability.
Cisco generated about $14.2 billion of operating cash flow in fiscal 2026, essentially unchanged from the previous year despite 12% revenue growth. Inventory climbed to $5.69 billion from $3.16 billion, an increase of roughly 80%.
The inventory build does not by itself signal weak demand, but it puts more attention on cash conversion as AI shipments scale. Cisco’s order growth now has to progress through three stages: revenue recognition, operating profit and ultimately stronger cash generation.
Not directly. Nvidia dominates GPUs, while Cisco focuses on networking, switching, optics, security and management systems that connect and control AI infrastructure.
Cisco booked more than $1 billion of fiscal 2026 AI infrastructure orders from neocloud, sovereign and enterprise customers, showing that demand extends beyond the largest cloud operators.
Working capital absorbed more cash as Cisco scaled hardware shipments, with inventory rising to $5.69 billion from $3.16 billion. Flat operating cash flow does not signal weak demand by itself, but it makes cash conversion an important test as AI revenue expands.
No. The $7.5 billion target refers specifically to hyperscaler AI infrastructure revenue. Enterprise, sovereign and neocloud opportunities sit outside that forecast and broaden Cisco’s overall AI exposure.
No. Orders can be placed well ahead of shipment and revenue recognition. Cisco’s own $7.5 billion fiscal 2027 hyperscaler AI revenue target shows that the full order total does not convert within a single year.
Q1 fiscal 2027 gives Cisco a clear test. Revenue is guided to $18.0 billion to $18.2 billion, while adjusted gross margin is expected at 65% to 66% and adjusted operating margin at 35.5% to 36.5%.
A quarter near the top of the revenue range with operating margin still around 36% would show that Cisco’s AI expansion can keep lifting earnings even as hardware pressures gross margin. If operating margin starts falling with gross margin, the economics behind the AI growth become harder to defend.
That result will show whether the rally simply paused or whether Cisco’s valuation is starting to outrun its earnings growth.
Cisco’s next AI milestone is no longer the size of the order book. It is the profit produced when those orders become revenue.
