Cisco closed fiscal 2026 with $17.25 billion of quarterly revenue, up 18%, and $3.86 billion of net income, up 51%. Networking revenue grew 28%, total product orders grew 35%, and orders for AI infrastructure from hyperscalers reached $9.3 billion for the full year. The demand signal is exceptional. So is the balance-sheet response: inventory reached $5.69 billion, 80% above the prior year. Cisco has entered an AI-driven networking cycle. The question is how efficiently orders become revenue and cash.
The Headline Numbers
For the three months ended July 25, 2026, compared with the fiscal fourth quarter a year earlier:
| Metric | FY2026 Q4 | FY2025 Q4 | YoY Change |
|---|---|---|---|
| Revenue | $17,252M | $14,673M | +17.6% |
| Gross profit | $11,063M | $9,280M | +19.2% |
| Operating income | $4,264M | $3,087M | +38.1% |
| Net income | $3,859M | $2,550M | +51.3% |
| Diluted EPS | $0.97 | $0.64 | +51.6% |
| Cash from operations | $5,400M | $4,200M | +27% |
This was genuine operating leverage. Revenue added $2.58 billion, gross profit added $1.78 billion, and operating expenses grew only $606 million. Cisco retained $1.18 billion of the incremental gross profit as additional operating income.
Below operating income, interest and other income swung from an $88 million loss to $669 million of income. That $757 million improvement helped net income grow faster than operating income. The clean operating result was still strong; the 51% bottom-line growth rate simply contains a favorable non-operating contribution.
For the full year, Cisco reported $63.33 billion of revenue, up 12%; $15.37 billion of GAAP operating income, up 31%; and $13.27 billion of net income, up 30%. Quarterly acceleration finished a year that had already moved well beyond the low-growth profile of the preceding cycle.
Revenue Deep Dive: Networking Reclaims the Center
Cisco's product portfolio grew across every disclosed group. Networking supplied both the majority of revenue and the fastest large-category growth.
| Product or Service Group | FY2026 Q4 Revenue | YoY Change | Share of Revenue |
|---|---|---|---|
| Networking | $9,791M | +28% | 56.8% |
| Security | $2,226M | +14% | 12.9% |
| Collaboration | $1,167M | +12% | 6.8% |
| Observability | $275M | +6% | 1.6% |
| Services | $3,793M | 0% | 22.0% |
| Total | $17,252M | +18% | 100% |
Networking is the cycle. Revenue reached $9.79 billion and product orders grew 40%, marking the eighth consecutive quarter of double-digit networking-order growth. This is more than a campus-switch refresh. AI clusters require high-bandwidth, low-latency networking across accelerators, racks, data centers, and clouds, expanding the role of the network in the total system cost.
Security grew 14% to $2.23 billion. That is faster than Cisco's historical core but slower than Networking. Security matters strategically because it can attach policy, identity, and threat controls to traffic moving across Cisco infrastructure. The quarter shows momentum, but at 12.9% of revenue it remains far smaller than Networking.
Collaboration and Observability grew, but neither drove the result. Collaboration produced $1.17 billion, while Observability contributed $275 million. Observability includes capabilities added through Splunk, but its 6% growth and 1.6% revenue share make it an adjacency rather than the quarter's engine.
Services were flat at $3.79 billion. That stability is valuable because services carry a 69.4% GAAP gross margin, versus 62.6% for product. Yet flat services revenue diluted the consolidated growth rate while product revenue rose 24%. The mix moved toward the faster-growing, lower-gross-margin side of Cisco.
Growth was geographically broad: Americas revenue rose 18% to $10.40 billion, EMEA rose 19% to $4.35 billion, and APJC rose 14% to $2.51 billion. Cisco was not dependent on one region for the acceleration.
The Margin Story
Product mix shifted toward hardware, but both product and service gross margins improved on a GAAP basis and expense leverage expanded operating margin.
| Margin | FY2026 Q4 | FY2025 Q4 | Change |
|---|---|---|---|
| Product gross margin | 62.6% | 61.5% | +1.1pp |
| Services gross margin | 69.4% | 68.3% | +1.1pp |
| Total gross margin | 64.1% | 63.2% | +0.9pp |
| Operating margin | 24.7% | 21.0% | +3.7pp |
| Net margin | 22.4% | 17.4% | +5.0pp |
Gross margin expanded despite product growing faster than services. Product cost of sales increased to $5.03 billion from $4.19 billion, but product revenue grew even faster. Services cost fell to $1.16 billion from $1.20 billion on flat revenue. Both sides of the portfolio contributed.
Operating expenses grew 10%, well below revenue growth of 18%. R&D rose only 2.1% to $2.43 billion, while the combined sales, marketing, general, administrative, acquired-intangible amortization, and restructuring lines grew in aggregate but not nearly as fast as gross profit. That difference produced the 3.7-point operating-margin expansion.
The annual margin trajectory is more nuanced. FY2026 GAAP gross margin was 64.5%, slightly below FY2025's 64.9%, while operating margin rose to 24.3% from 20.8%. The annual improvement came from operating-expense leverage rather than a richer gross-margin mix. Q4 improved both layers, which is why the exit rate looks stronger than the full-year average.
The $9.3 Billion Question: Orders, Inventory, and Conversion
Cisco disclosed $4.0 billion of hyperscaler AI-infrastructure orders in Q4, bringing the fiscal-year total to $9.3 billion. It delivered approximately $4.0 billion of AI-infrastructure revenue in FY2026 and expects $7.5 billion in FY2027. Total product orders grew 35%; even excluding hyperscalers, they grew 25%.
Orders are not revenue. The conversion requires components, manufacturing capacity, customer acceptance, shipment, and sometimes installation. Inventory is where that execution burden appears. Inventory rose from $3.16 billion at FY2025 year-end to $5.69 billion at FY2026 year-end, an 80% increase. Revenue rose 12% over the same fiscal-year comparison.
The inventory build can be read two ways. The bullish reading is that Cisco is procuring against visible demand and reducing the risk that supply constraints delay high-value AI systems. A $9.3 billion order base supports carrying more components and finished goods. The bearish reading is that order timing, hyperscaler concentration, or technology transitions could leave Cisco holding inventory that ages faster than traditional networking equipment.
Contracted revenue adds support. Remaining performance obligations reached $46.73 billion, up 7%, split almost evenly between $23.44 billion of product and $23.30 billion of services. Deferred revenue reached $29.78 billion, up 3%. These balances do not eliminate execution risk, but they show that a substantial part of future activity is already under contract or paid in advance.
Cash generation is the test that resolves the debate. Q4 operating cash flow rose 27% to $5.4 billion, but full-year operating cash flow was $14.2 billion, flat with FY2025 despite much higher revenue and profit. If inventory converts as planned, working capital should release cash. If it keeps growing faster than revenue, the order boom will look less efficient than the income statement suggests.
Tracking a $63 Billion Network Platform in Plain Text
The Beancount ledger forces Cisco's hardware cost, software and service economics, R&D, operating expenses, tax, and net income into one auditable transaction. Revenue is a negative credit; costs and expenses are positive debits.

Cisco's annual history shows a portfolio that grew slowly until the AI networking cycle and Splunk-era cost structure changed the slope.
| Fiscal Year | Revenue | Gross Margin | Operating Margin | Net Income | Inventory |
|---|---|---|---|---|---|
| FY2021 | $49,818M | 64.0% | 28.0% | $10,591M | $1,559M |
| FY2022 | $51,557M | 62.5% | 27.7% | $11,812M | $2,568M |
| FY2023 | $56,998M | 62.7% | 27.8% | $12,613M | $3,644M |
| FY2024 | $53,803M | 64.7% | 25.4% | $10,320M | $3,373M |
| FY2025 | $56,654M | 64.9% | 23.9% | $10,180M | $3,164M |
| FY2026 reported | $63,325M | 64.5% | 24.3% | $13,267M | $5,694M |
From FY2021 through FY2025, revenue grew only 13.7% in total and net income declined 3.9%. Gross margin held near the mid-60s, but operating margin fell as R&D, acquired technology, sales investment, and restructuring absorbed more of gross profit.
FY2026 broke that pattern. Revenue grew 11.8% in one year, net income grew 30.3%, and operating margin recovered 0.4 points. Q4 exited at an even higher 24.7% operating margin. The acceleration is visible.
Inventory is the outlier. It grew 265% from FY2021 to FY2026, far faster than revenue. Much of the latest jump may be deliberate preparation for AI demand, but it raises the execution standard. Cisco has to turn a historically unusual balance-sheet commitment into shipments and cash.
The Verdict: Bull vs. Bear
Bull Case
- Q4 revenue grew 18%, gross profit 19%, operating income 38%, and net income 51%; the operating leverage was broad and measurable.
- Networking revenue grew 28% and networking orders grew 40%, with eight consecutive quarters of double-digit order growth.
- Product orders grew 35% overall and 25% excluding hyperscalers, evidence that demand extends beyond a small group of AI infrastructure buyers.
- RPO reached $46.73 billion and deferred revenue $29.78 billion, providing contracted visibility behind the growth plan.
- Q4 operating cash flow grew 27% to $5.4 billion, showing that the quarter's profit was not purely accrual-based.
Bear Case
- Inventory rose 80% to $5.69 billion in one year, far faster than annual revenue, increasing obsolescence and order-conversion risk.
- Services revenue was flat while lower-margin product revenue grew 24%, making continued gross-margin improvement harder if product mix keeps rising.
- Full-year operating cash flow was flat at $14.2 billion despite 12% revenue growth and 30% net-income growth.
- Interest and other income improved by $757 million year over year in Q4, so net-income growth materially exceeded the operating improvement.
- Hyperscaler AI orders are large and can be concentrated; changes in a few deployment schedules could move revenue between periods.
Our Take: Cisco is in the strongest demand cycle its five-year ledger shows. The 35% product-order growth, 28% Networking revenue growth, and rising RPO make the acceleration difficult to dismiss as a single-quarter shipment anomaly. The bullish verdict is warranted. But the inventory build is not a footnote; it is the physical bet behind the order book. Cisco now has to convert $9.3 billion of AI orders and an 80% inventory increase into revenue and cash without sacrificing gross margin. If FY2027 operating cash flow catches up to earnings, the networking supercycle thesis will be validated. If not, the order headline will have outrun the economics.
