Cisco line by line: where every dollar that comes in goes

The figures in this report cover Cisco Systems' fiscal year 2025, which closed on 26 July 2025 and was filed with the regulator on 3 September 2025. It is the most recent complete, audited year that exists as a public document.

Fiscal 2026 closed in late July 2026, but its annual filing is not out yet. Any full-year 2026 figure circulating today comes from an earnings release, not from the audited document. This report keeps the two apart: section 8 uses the three quarters of 2026 that have been filed, and says so.

The company reports in millions of dollars and every figure here is presented the same way. Each number comes from the corresponding statement; none is estimated. The arithmetic of the income statement was verified line by line before publishing: gross profit equals revenue minus cost of sales, operating income equals gross profit minus operating expenses, and so on down to the last line.

This is the fiscal 2025 income statement drawn as what it actually is: a flow. A stream comes in from the left — revenue — and narrows every time something peels off. The thickness of each branch is proportional to its amount, so what you see is literally the relative size of every line item.

How to read it

• The branch running straight along the top is what survives: gross, then operating, then net. It gets thinner each time.
• Everything peeling away below is what was consumed. Its thickness against the opening stream is its real weight, not its headline.
• The percentage next to each item is always calculated on total revenue, never on the nearest subtotal. That is the only way to compare two items from different stretches without fooling yourself.

In one sentence: of every 100 dollars billed, 35 go into producing and delivering what was sold, 44 into running the business — researching, selling, administering and restructuring — 3 between interest and taxes, and 18 are left.

Gross margin for the year was 64.9%, the highest of the last five years. If the story stopped there, the reading would be that the company sells better than ever. The diagram shows why that is not enough: $25,030 million is consumed between gross profit and operating income, and that is where the result was decided.

Over four years revenue grew 13.7% cumulatively and research and development spending grew 42.0%. It went from consuming 13.1 of every 100 dollars billed to consuming 16.4. Operating margin travelled the opposite way: from 25.8% to 20.8%. These are the highest revenues of the last five years sitting alongside the lowest operating margin of the last five years.

What every dollar billed turns into, year by year

The flow diagram in section 2 freezes a single year. This one stacks all five: each column sums to 100% of that year's revenue, so what you see moving is the split, not the size.

The exact bridge from one year to the next

The two charts above show direction. This one shows the accounting: what added and what subtracted, item by item, between the 2024 operating income and the 2025 one.

This is a description, not a diagnosis. A sustained increase in research spending can reflect a deliberate investment cycle or a competitive necessity, and the income statement alone cannot tell the two apart. What it does allow us to state with certainty is the fact: the item grew three times faster than revenue.

Operating income fell from $12,181 million to $11,760 million, down 3.5%. Net income fell from $10,320 million to $10,180 million, down 1.4%. The difference is not in the business: it is in the tax line.

The effective tax rate went from 17.7% to 8.3% in two years. Had the 2023 rate applied in 2025, tax would have been roughly $1,960 million instead of $920 million, and net income would have landed near $9,140 million instead of $10,180 million.

At year end, current assets totalled $34,986 million and current liabilities $35,064 million. The current ratio is 1.00x. The quick ratio in its strict definition — cash, marketable securities and receivables over current liabilities — comes to 0.65x. Read without context, that would describe a company running on tight liquidity.

Context changes what the figure means. Inside those $35,064 million of current liabilities sit $16,416 million of deferred revenue: money already collected for service and support contracts not yet delivered. In accounting terms it is a liability; in practice it is an obligation to perform a service, not to hand back cash. Excluding it, the same quick ratio comes to 1.22x.

Adding the non-current portion, total deferred revenue stood at $28,779 million. The general lesson runs beyond this company: a liquidity ratio computed blind can describe as strain what is in fact the normal working of a business model. Before interpreting a ratio, open up the denominator.

The 2025 income statement carries decisions made in 2024. That year the cash flow statement records $25,994 million in business acquisitions and $31,818 million of long-term debt issued. The footprint is still visible two years later.

Interest expense multiplied by 3.7 between 2023 and 2025. That increase does not show up in the operating margin — it sits below that line — and it is one of the reasons pre-tax income fell further than operating income.

On the asset side, goodwill stands at $59,136 million: 48.4% of the entire balance sheet. Added to other intangibles, $68,311 million, it exceeds total equity of $46,843 million by 46%.

On the liability side, total debt — short and long term — was $28,093 million against $16,110 million in cash and marketable securities, leaving net debt of $11,983 million. In 2023, before the acquisition cycle, long-term debt was $6,658 million.

The income statement says how much was earned; the cash flow statement says how much was collected. In 2025 net cash from operating activities was $14,193 million and purchases of property and equipment $905 million, leaving free cash flow of $13,288 million.

That free cash flow exceeds net income of $10,180 million by 30.5%. Much of the gap is explained by two items in the cash flow statement itself: stock-based compensation, $3,641 million, which reduces earnings without any cash leaving, and amortisation of intangibles, $1,028 million, of the same nature.

Stock-based compensation not consuming cash does not mean it is free. The treasury does not pay it: existing shareholders do, through dilution, and it amounted to 35.8% of the year's net income. Any reading of free cash flow that ignores that item is telling half the story.

On the spending side, the company paid $6,437 million in dividends and repurchased $6,000 million of its own stock: $12,437 million in total, or 93.6% of the year's free cash flow. Average shares outstanding fell from 4,222 million in 2021 to 3,976 million in 2025.

As of 14 August 2026, with the stock at $111.68 and a market capitalisation of $488,265 million, that $13,288 million of free cash flow equates to a 2.7% yield on price. As a stated reference point, and without drawing any conclusion from it, the 10-year US Treasury yielded 4.63% on 13 August 2026.

Fiscal 2026 has no annual filing yet, but its first three quarters do exist as filings. Set against the first three of the prior year, they describe a different trajectory from the one full-year 2025 showed.

The nine-month operating margin recovers 3.4 percentage points, landing above the 22.6% of full-year 2024 though still below the 26.4% of 2023. The fourth quarter, which at this company is usually the largest of the year, has not been filed and therefore does not enter this comparison.

One derived figure, with its derivation shown so anyone can reproduce it: subtracting the first nine months of fiscal 2025 ($41,981 million) from the full year ($56,654 million) gives a fourth quarter of $14,673 million. That is arithmetic on filed figures, not an estimate.

A flow diagram of the income statement is a comprehension tool, not a verdict. Its limits are worth keeping in mind, and they are the same for any company:

• It does not break out segments or geographies. A consolidated margin can hide one business line expanding and another contracting, cancelling each other out.
• It does not separate the recurring from the one-off. The $744 million of restructuring weighs the same today as any other operating item, and by its nature should not repeat every year.
• It does not reflect timing of collection. Revenue recognised is not cash received; that is what the cash flow statement is for, which this report looks at separately in section 7.
• It does not incorporate price. Everything above describes the business, not whether the stock is cheap or expensive — a different question, one that requires assumptions about the future and that this report does not answer.

Anyone who wants to go further has an open road: the same documents that feed this report are public and free, and the diagram can be rebuilt for any company filing with the same regulator. The technique is what transfers; the particular company is only the example.
