Cisco Q4 FY2026 Results (12 August 2026): $17.3bn Revenue and $9.3bn of AI Orders — Why Gross Margin Fell 2.1 Points and Operating Margin Rose Anyway

Cisco reported fourth-quarter and full-year fiscal 2026 results after the US close on Wednesday 12 August 2026, and the quarter broke out of the band its own annual guidance had appeared to lock it into. Revenue was $17.25 billion against a $16.7–16.9 billion guide, non-GAAP earnings per share were $1.22 against $1.16–1.18, and non-GAAP operating margin was 35.9% against a 34–35% guide. The number this post was built around resolved too: hyperscaler AI infrastructure orders reached $9.3 billion for the fiscal year against the $9 billion target, with $4 billion of that taken in the fourth quarter alone. And the gap between orders and revenue — $9.3 billion booked, roughly $4 billion recognised — now has a date on it, because Cisco guided fiscal 2027 AI infrastructure revenue to $7.5 billion and total revenue to $72.2–73.4 billion. The most instructive line in the release is not any of those. It is that non-GAAP gross margin fell 2.1 points year on year and non-GAAP operating margin still rose 1.6 points.

What actually happened

The framing going into this release was that a tight full-year band left the fourth quarter with almost no room to be interesting on the revenue line. That turned out to be wrong, and the way it was wrong is the story: Cisco did not land inside the band, it cleared it by $352 million, and the full-year figure cleared its own ceiling too.

Every figure above comes from Cisco's Q4 FY2026 press release as furnished to the SEC. Product revenue was $13.46 billion, up 24%; services revenue was $3.79 billion, flat. By geography, Americas rose 18%, EMEA 19% and APJC 14% — all three faster than the quarter before.

Chief financial officer Mark Patterson said the company delivered "record revenue, non-GAAP operating income and EPS, all exceeding the high end of our guidance ranges," and chair and chief executive Chuck Robbins described "a very strong close to fiscal 2026, marking another record year for Cisco."

The $9bn that was $9.3bn — and the $7.5bn that follows

The centre of gravity in this release was a demand metric that never appears in the financial statements, and it landed slightly ahead of target.

Cisco booked $4 billion of hyperscaler AI infrastructure orders in the fourth quarter, taking the fiscal 2026 total to $9.3 billion against the $9 billion it had guided to in May. The preview arithmetic required roughly $3.7 billion in the quarter; the company delivered $4 billion, more than double the $1.9 billion taken in the third quarter.

The more consequential disclosure was the conversion schedule. Cisco delivered approximately $4 billion of AI infrastructure revenue in fiscal 2026 and expects $7.5 billion in fiscal 2027 — close to double, and the first time the company has dated the gap rather than merely described it. That is what turns a demand metric into a revenue forecast, and it is why the fiscal 2027 guide carried more information than the quarter did.

Why gross margin fell and operating margin rose anyway

This is the part of the release worth reading twice, because the two headline profitability numbers moved in opposite directions and most summaries will pick one.

The mix effect was real and arrived on schedule. Non-GAAP total gross margin was 66.3% against 68.4% a year earlier. Non-GAAP product gross margin was 64.8% against 67.5% — down 2.7 points. Selling systems and optics at volume to a handful of hyperscale buyers with enormous purchasing leverage is lower-margin work than selling enterprise campus equipment through partners, and the percentage records that faithfully.

What offset it was operating expense discipline of a kind that does not usually accompany an 18% revenue quarter.

Non-GAAP operating expenses were $5.24 billion, up 5%, while revenue grew 18%. That 3.7-point improvement in the expense ratio more than paid for the 2.1 points lost at the gross margin line, and the difference is the entire reason operating margin rose. Patterson framed the same fact differently, noting that fiscal 2026 produced Cisco's "highest productivity metrics in 30 years measured by revenue, non-GAAP operating margin, and earnings per employee."

The mechanism generalises beyond Cisco. When a lower-margin product mix scales into a fixed-ish cost base, the gross margin percentage and the operating margin percentage can diverge for years. Reading only the first produces the conclusion that AI revenue is diluting profitability; reading both produces the conclusion that it is diluting the rate while increasing the dollars — non-GAAP operating income was $6.20 billion, up 23%.

One caution on the GAAP line. GAAP EPS of $0.97 rose 52%, but that figure includes $869 million of gains on investments flowing through other income, worth $0.22 per share in the reconciliation, against $511 million of restructuring charges worth $0.13. Non-GAAP EPS rose 23%. The gap between the two growth rates is mostly portfolio marks, not operations.

The half nobody was previewing

Two questions sat underneath the AI headline, and they resolved in opposite directions.

The first was concentration: whether the company was growing on a handful of very large customers. The answer was no, and emphatically. Total product orders rose 35% year on year including hyperscalers and 25% excluding them, with double-digit growth across every geography and customer market. That ex-hyperscaler figure accelerated from 19% a quarter earlier — the enterprise base got faster, not slower, while the AI business doubled its order intake. Networking product orders grew 40% year on year, an eighth consecutive quarter of double-digit growth, which Cisco characterised as a networking supercycle.

The second was security. Q4 Security revenue was $2.23 billion, up 14%, a genuine inflection off the flat third quarter that this post flagged as the least-previewed line in the release. But the full year tells a harsher version: Security revenue was $8.23 billion for fiscal 2026, up just 2%, against Networking at $34.67 billion and 22% growth. Collaboration was $4.30 billion (+4%) and Observability $1.10 billion (+4%).

One quarter of 14% growth does not undo a year of 2%, but it changes the direction of the question from whether the segment can grow to whether it can keep doing so. Cisco closed two acquisitions inside the quarter that speak to the same ambition: Galileo Technologies in observability, and Astrix Securities in non-human identity security.

What the peers had already shown

Two companies exposed to the same spending reported in the 24 hours before Cisco, and both showed committed demand running far ahead of delivered revenue. Supermicro reported $11.1 billion of quarterly net sales while stating more than $60 billion of new orders, per its release filed with the SEC. CoreWeave reported $2.58 billion of revenue against a backlog of roughly $104 billion, in its second-quarter release.

The ratio column measures how much of each company's story is still a promise. Cisco's is the smallest by a wide margin, and that is the point rather than a criticism: the AI line is an increment on top of an enterprise franchise that already converts, which is why a $9.3 billion order book sits alongside $63.33 billion of recognised annual revenue rather than dwarfing it. The three businesses carry very different mixtures of delivered and undelivered work, and should not be read with the same instrument.

What the fiscal 2027 guide commits to

The guide was the part with the longest half-life, and it stepped up rather than steadying.

Cisco guided fiscal 2027 revenue to $72.2–73.4 billion and non-GAAP EPS to $5.05–5.11, with GAAP EPS of $4.00–4.06. Against the $63.33 billion just reported, the revenue range implies 14.0% to 15.9% growth — faster than the 12% delivered in fiscal 2026, which is an unusual shape for a company of this size guiding twelve months ahead. For the first quarter, revenue of $18.0–18.2 billion implies a 4.3% to 5.5% step up from the $17.25 billion just reported, with non-GAAP gross margin guided to 65–66% and non-GAAP operating margin to 35.5–36.5%.

Two things sit inside those numbers that are easy to miss. The gross margin guide of 65–66% is below the 66.3% just delivered, so the company is telling the market in advance that mix pressure continues. And the FY27 guidance explicitly contemplates the actual impact of tariffs as currently understood — the same trade-cost channel that ran through the whole earnings season, covered in our look at how tariff costs and refunds moved US500 margins. A change in that policy between now and the prints shows up in this line first.

The balance sheet carries the physical version of the same commitment. Inventories closed fiscal 2026 at $5.69 billion against $3.16 billion a year earlier, a $2.5 billion build, and financing receivables rose as well. Companies stock components ahead of a ramp they expect; the line is a statement of intent, and it is also the line that looks worst if the ramp slips.

What it touches, and what it does not

Cisco is a component of the S&P 500 and the Nasdaq 100, but it is not one of the handful of mega-caps that drive most of a daily index move. The larger channel is informational: Cisco sits between hyperscaler capital expenditure budgets and the equipment those budgets buy, so its order commentary is one of the few near-real-time reads on whether announced datacentre plans are still converting into purchase orders. This quarter that read was affirmative, and unusually broad — 35% order growth including hyperscalers, 25% without them, double-digit in every geography.

Cisco also returned $3.2 billion to shareholders in the quarter, declaring a $0.42 dividend payable 21 October 2026 to holders of record on 2 October, and repurchasing roughly 13 million shares at an average price of $111.53, leaving $8.1 billion of authorisation outstanding.

What this is not is a currency event. There is no plausible channel from a networking company's fiscal fourth quarter to the relative pricing of the majors, and pretending otherwise would be worse than saying nothing. The one honest FX connection is translational and runs the other way: EMEA revenue grew 19% and APJC 14%, and what those non-dollar lines are worth in reported dollars depends on where the US dollar has been — a mechanical effect that flatters or trims reported growth without any change in units sold. That is the same dollar whose interest-rate, growth and risk factors the meter scores, and the same dollar that July's CPI print addressed hours before Cisco reported. That print landed quietly: headline CPI rose 0.1% on the month for an annual 3.4%, core rose 0.2% for an annual 2.5%, both in line with consensus (Bureau of Labor Statistics; detail in our July CPI write-up). An in-line inflation print settled the dollar leg of the day before the equity leg began — which is why the two events shared a date and almost nothing else. More on how the framework fits together on the about page.

What would change the picture

Three things, in order of how much they would move the interpretation.

The $7.5 billion of fiscal 2027 AI revenue is now a commitment rather than an aspiration, and the quarterly cadence against it is the single most informative number in the next four releases — a first quarter that does not carry roughly a quarter of it would say shipment slots, not demand, are the binding constraint. The gross margin guide of 65–66% is a step down from 66.3%, so the question through fiscal 2027 is whether operating leverage keeps outrunning mix the way it did this quarter, or whether the 5% opex growth rate was a year-end artefact. And the $2.5 billion inventory build is the balance-sheet expression of the guide: it converts cleanly if the ramp lands and sits there if it does not.

None of that requires a view on where the shares go. It requires knowing which number answers which question — which is the same discipline the preview version of this page argued for, applied now to figures that exist.
