Cisco grew FY2026 revenue 12% to $63.3bn and GAAP EPS 31% to $3.33, but essentially all of it came from AI-infrastructure-led Networking (+22%) while Security (+2%), subscriptions (+1%) and services (flat) stalled — and product mix cost 3.6 points of product gross margin.

Cisco's first real AI hardware year: revenue up 12%, but the mix is changing the company
Cisco closed fiscal 2026 on July 25, 2026 with $63.3 billion of revenue, up 12%, and GAAP diluted earnings per share of $3.33, up 31%. (Cisco's fiscal year runs August to late July, so "fiscal 2026" covers roughly August 2025 through July 2026 — its FY2026 is not the same thing as calendar 2026.)
Almost all of the growth came from one place. Product revenue rose 16% to $48.3 billion; services revenue was flat, at $15.0 billion versus $15.0 billion a year earlier. Inside products, the Networking category alone added $6.4 billion of the company's $6.7 billion total revenue increase.
The specific driver is named in the filing: AI infrastructure sold to hyperscalers — the handful of very large cloud and internet companies that build data centers at enormous scale. Management states that this business "represented approximately 6% of total revenue in fiscal 2026 compared with less than 2% in fiscal 2025." In the accompanying earnings release, Cisco quantified it as roughly $4 billion of AI infrastructure revenue in FY2026 against $9.3 billion of AI infrastructure orders taken, with $7.5 billion of revenue expected in FY2027.

Where the profit growth actually came from — and where it didn't
Operating income rose 31%, faster than revenue's 12%, and operating margin — the share of revenue left after the cost of goods and all operating expenses, before interest and tax — improved 3.5 percentage points to 24.3%. That improvement is genuine operating leverage rather than cost-cutting: R&D, sales and marketing and G&A together grew only 3% (to $23.9 billion) against 12% revenue growth, so those costs fell from 41.1% to 37.7% of revenue. Headcount spending did rise — R&D was up 3% on "higher headcount-related expenses reflecting our investments in AI" — it just rose far more slowly than sales.
Below the operating line, two items distort the year-over-year comparison in opposite directions, and they roughly offset:
FY2026 was flattered by investment gains. "Other income (loss), net" swung from a $68 million loss to a $1,245 million gain, a $1.3 billion move. Nearly all of it is unrealized: gains on non-marketable equity securities — Cisco's stakes in private companies, written up when those companies raise money at higher valuations — went from $56 million to $1,409 million. No cash changed hands, and the 10-K warns these marks "may be impacted by future observable financing rounds at varying valuations," i.e. they can reverse.
FY2025 was flattered by a tax benefit. Cisco's effective tax rate was only 8.3% in FY2025 because of a $720 million discrete tax benefit tied to a U.S. Tax Court opinion on the 2017 Tax Act's treatment of deemed foreign dividends. FY2026's rate was 17.1%, a more normal level.
Strip both out and the underlying picture is roughly what operating income already shows: about 31% growth, driven by volume and expense discipline. That is why GAAP EPS grew 31% while Cisco's own non-GAAP EPS — which excludes the investment marks, restructuring and intangible amortization — grew only 14%. The 31% is the flattering number; 14% is closer to the operating reality, and both are good.
The margin problem hiding inside the growth
Gross margin — the share of revenue left after the direct cost of making and delivering the product — fell 0.4 points to 64.5%, and product gross margin fell 0.5 points to 63.2%, despite 16% product revenue growth. The 10-K's own bridge explains why:
Non-recurrence of FY2025 supplier legal dispute charge
+0.8 pts
Other
+0.1 pts
FY2026 product gross margin
63.2%
The mix hit is the whole story, and management is explicit that "the negative impacts from product mix were primarily due to higher Networking revenue" — the AI infrastructure gear that is driving growth carries lower margins than what it is displacing in the sales mix. Productivity gains that would otherwise have offset it "were adversely impacted by higher memory costs."
You can see the same effect geographically: Americas gross margin fell 3.1 points, from 68.2% to 65.1%, "driven by negative impacts from product mix" — the Americas is where the US hyperscalers buy. EMEA and APJC margins both rose.
Two of the six positive bridge items (lower intangible amortization, the absent supplier charge) are comparison effects rather than improvements. Without them, product gross margin would have fallen about 2.2 points.
Takeaway: Cisco has swapped a stalled high-margin business for a fast-growing lower-margin one. Networking product revenue grew 22% and carried the entire company, while Security grew 2%, subscription revenue grew 1%, and services revenue shrank. The 3.6-point product-mix drag on gross margin is the price of the AI infrastructure boom — profitable today only because operating expenses grew 3% against 12% revenue growth. If that expense leverage stops before the mix shift does, margins go the other way.

Networking (switching, routing, wireless and servers) grew "primarily driven by our AI Infrastructure solutions, which include Cisco Silicon One based systems and optics," with double-digit increases in Service Provider Routing, Data Center Switching, Wireless and servers.
The other three matter because of what they were supposed to be. Security — the category Cisco spent $28 billion on Splunk to reinforce — grew 1.7%, "primarily driven by growth in our SASE and Network Security offerings." Observability added $40 million on a $1.1 billion base, and even that came from network assurance while "the observability suite offerings" declined. Collaboration grew 3.5%.
The recurring-revenue story is similarly flat. Total software revenue was $23.2 billion, up 4%; total subscription revenue rose 1.4% to $32.0 billion, and the services half of it actually fell ($13,663M from $13,743M). For a company that spent most of the last decade telling investors it was becoming a software and subscription business, FY2026 was a hardware year.
Quality of earnings: cash did not follow profit
Net income rose $3.1 billion. Cash generated by operations was $14,177 million, essentially flat against $14,193 million. Two things absorbed the difference:
Inventory nearly doubled, from $3,164M to $5,694M (+80%), "reflecting increased demand for our Cisco Silicon One and the impact of higher memory prices." Cisco is also making larger purchase commitments and prepayments to secure memory and components.
A $2.3 billion final U.S. transition tax payment under the 2017 Tax Act — a one-off that does not repeat.
The 10-K is unusually direct about the risk this creates. Because Cisco commits to component purchases on forecast, "hyperscalers or other large customers may change their orders or buying patterns with us with limited advance notice, which could result in amounts that we have prepaid or deposited with contract manufacturers and suppliers for such commitments being not fully recoverable if the related orders are not fulfilled." Concentrating growth in a small number of very large buyers while pre-buying scarce memory is a real balance-sheet exposure, not a boilerplate risk factor.
Capital returns stayed steady: $6,106M of buybacks and $6,553M of dividends, $12.7 billion combined against $14.2 billion of operating cash flow. Note that buybacks barely moved the share count — diluted shares fell only 0.3%, from 3,998M to 3,987M — because share-based compensation issuance offsets most of the repurchases. EPS growth here is earnings growth, not financial engineering. Total debt rose to $29.5 billion from $28.1 billion; cash and investments were roughly flat at $15.9 billion.
The fourth quarter, and the order book
Q4 (the three months to July 25, 2026) was stronger than the full year: revenue $17,252M, up 17.6%, with product revenue up 24% and services again flat. Operating margin reached 24.7%, up 3.7 points, and GAAP EPS rose 52% to $0.97 — though non-GAAP EPS rose 23%, the gap again reflecting investment marks and the absence of the prior-year supplier charge. Q4 gross margin actually rose 0.9 points, but only because that FY2025 legal charge did not recur.
Q4 also carried a $511 million restructuring charge under a new plan announced in the quarter "to allow us to invest in key growth opportunities including silicon, optics, security and AI." Total pre-tax cost is estimated at up to $1 billion, substantially complete by end of FY2027. Cisco says it expects "to reinvest substantially all of the cost savings from these restructuring plans," so this is a reallocation of spending toward silicon and AI, not a margin-expansion program.
The forward indicator worth more than the revenue line is orders. Per the earnings release, Q4 total product orders rose 35% year over year, and 25% excluding hyperscalers — meaning the demand strength is broad, not solely an AI-datacenter artifact. Networking product orders grew 40%, an eighth consecutive quarter of double-digit growth. Remaining performance obligations rose 7% to $46.7 billion, with product RPO up 9%.

Cisco is guiding to faster revenue growth in FY2027 than it delivered in FY2026 — unusual for a company this size, and consistent with the 35% Q4 order growth and the backlog. About $3.5 billion of the roughly $9.5 billion implied revenue increase is the step-up in AI infrastructure revenue from ~$4.0 billion to $7.5 billion, so roughly 60% of the guided growth is expected to come from everything else.
Two qualifications on the EPS guidance. First, it assumes a GAAP effective tax rate of about 14.5%, below FY2026's actual 17.1%; holding the tax rate flat would take roughly three points off the guided ~21% GAAP EPS growth. Second, GAAP guidance excludes future investment gains or losses, which means the $1.4 billion of unrealized private-company marks that helped FY2026 are not assumed to repeat — a reason the guided GAAP EPS growth (+21%) sits below the guided non-GAAP growth path in spirit even though it prints higher.
Our read. The demand signal is the most credible part of this filing: 25% order growth excluding hyperscalers is not an AI story, it is a genuine enterprise networking refresh, and it is what makes the FY2027 revenue guide plausible rather than aspirational. The risk is on the margin and the balance sheet, not the top line. Product mix cost 3.6 points of product gross margin this year and the AI mix is set to grow faster still in FY2027; memory costs are rising; inventory is up 80% and increasingly pre-committed to a concentrated set of buyers who can change their orders with little notice. Cisco earned its way through all of that in FY2026 by holding operating expense growth to 3%. That lever has a floor, and the company just told investors it will reinvest its restructuring savings rather than bank them. The businesses that were supposed to diversify Cisco away from hardware cycles — Security at +2%, subscriptions at +1% — did not contribute this year, which makes the next two years more dependent on hyperscaler capital spending than the company's strategy of the last decade intended.
