Reading Microsoft's Annual Report: A 10-K Walkthrough

How Microsoft's annual report is organized

Microsoft's annual report is a Form 10-K filed at the end of July, a month after its fiscal year closes on June 30. The fiscal 2025 filing, submitted in July 2025, is the one this walkthrough uses. Like every 10-K it runs through the standard items: the business description in Item 1, risk factors in Item 1A, management's discussion in Item 7, and the audited statements and notes in Item 8.

Three features make Microsoft's filing a different read from a hardware company's. Revenue is organized into three reportable segments rather than product lines on the face of the income statement. A large deferred revenue balance sits on the liability side of the balance sheet. And the asset side carries one of the biggest goodwill balances in corporate America. Each is a window into how the business actually works, and each has its own section below.

One practical note before you start. Microsoft reshuffled what sits inside each segment at the start of fiscal 2025 and restated the prior year to match, which the filing explains up front. Segment definitions are management's choice, not an accounting law, so always check the description of what moved before comparing across years.

The three-segment structure and what each one earns

Microsoft reports its results through three segments, and the fiscal 2025 10-K puts real weight behind each. Productivity and Business Processes earned $120.8B of revenue, Intelligent Cloud $106.2B, and More Personal Computing $54.7B, for a total of $281.7B, up 15 percent on the year. The segment note also shows operating income for each, which is where you learn that this is a business with three engines, not one.

The segment labels hide more than they reveal, so the product detail in the revenue note matters. As of July 2026, the fiscal 2025 figures break down like this:

Two observations fall out of the table. First, the old image of Microsoft as a Windows company is a decade stale: Windows and devices are now a $17.3B line inside a $281.7B company. Second, the growth engine is subscriptions and cloud consumption. Microsoft disclosed alongside the fiscal 2025 results that Azure alone passed $75B of annual revenue. Gross margin for the whole company was 68.8 percent, and it has held between 68 and 70 percent for five years, the signature of software economics at scale.

The rest of the income statement is worth thirty seconds of arithmetic. Research and development cost $32.5B, about 11.5 percent of revenue, and sales and marketing another $25.7B. Operating income came to $128.5B, a 45.6 percent operating margin, and net income was $101.8B, or $13.64 per diluted share, as of the July 2026 data cut. Very few companies at any scale convert 36 cents of every revenue dollar into after-tax profit; when one does, the segment note tells you which engines are doing it.

Deferred revenue: the subscription tell

The single best line for judging a subscription business sits on the liability side of Microsoft's balance sheet, labeled unearned revenue. At June 30, 2025 it stood at $64.6B in current liabilities plus $2.7B non-current, about $67.3B in total, up from $60.2B a year earlier. This is cash customers have already handed over for services Microsoft has not yet delivered.

Accounting treats it as a liability because Microsoft still owes the service. Economically it is closer to a gift: customers finance the company in advance, interest-free, and renew the arrangement every year. When you read any subscription business, from software to gyms, this line growing in step with revenue is the tell that the model is working. The broader pattern is covered in recurring revenue business models.

The direction of travel matters more than the level. Deferred revenue rising about 12 percent while revenue rose 15 percent says customers keep paying ahead at roughly the pace the business grows. A subscription company whose deferred revenue stalls while reported revenue accelerates deserves a hard second look, because it may be pulling revenue forward. The notes explain what portion unwinds within a year, one more reason the notes to the financial statements repay attention.

Goodwill: the residue of acquisitions

Goodwill of $119.5B sat on Microsoft's balance sheet at June 2025, with another $22.6B of acquired intangibles beside it, and together they are a history of the company's shopping. Goodwill is the amount paid for an acquired business above its identifiable assets. It is not a thing you can sell; it is a record of what management once paid for growth.

The fiscal 2024 10-K shows where the biggest slug came from: about $51B of goodwill arrived with the Activision Blizzard purchase, which closed in October 2023. LinkedIn and Nuance left similar, smaller deposits in earlier years. Nothing about a large goodwill balance is automatically bad. It becomes information when it changes: an impairment charge means management has formally admitted an acquisition is worth less than it paid.

For a reader, two habits suffice. Compare goodwill to total assets ($119.5B against $619.0B, about a fifth) to grasp how acquisition-built the company is, and scan the notes each year for impairment tests, which the rules require at least annually. Microsoft's record here has been quiet, which is itself a data point. How a hardware-centered balance sheet differs is visible in reading Apple's annual report, where goodwill barely registers.

The acquired intangibles line beside goodwill behaves differently and is worth separating in your head. Those $22.6B of intangibles, things like acquired technology and customer relationships, amortize through the income statement on a schedule, quietly reducing reported profit each quarter. Goodwill does not amortize; it simply sits until an impairment forces a reckoning. One erodes earnings predictably, the other threatens them occasionally, and the notes distinguish the two in a single table.

The cash flow statement: the AI buildout in one line

Microsoft's fiscal 2025 cash flow statement records one of the largest capital spending programs in business history, and you can read it in a single line. Capital expenditures were $64.6B, up from $44.5B in fiscal 2024, nearly half of the year's $136.2B of operating cash flow. Property and equipment on the balance sheet jumped from $154.6B to $229.8B in twelve months. That is the AI data center buildout, stated in dollars rather than press releases.

The consequence shows one line lower. Free cash flow, operating cash flow minus capex, came in near $71.6B, lower than the prior year even though operating cash flow rose $17.6B. A company can grow cash generation and shrink free cash at the same time when it invests this hard, and only the cash flow statement shows the tradeoff. The concept is unpacked in understanding capital expenditures.

The buildout also reaches the balance sheet through a quieter door: leases. Microsoft's finance lease obligations grew to about $69B at June 2025 from $46B a year earlier, largely data center capacity contracted rather than constructed. Add those leases to conventional borrowings and total obligations of roughly $112B stand against $94.6B of cash and short-term investments. The balance sheet remains a fortress, but a reader who stops at the small long-term debt line misses where the real commitments now accumulate.

Whether the spending earns its keep is the open question of the decade for Microsoft, and honest readers should hold it as a question. What the statements can tell you is the scale of the bet and the capacity funding it: financing activities still returned $18.4B via buybacks and $24.1B in dividends during the same year, which says the core business throws off enough cash to arm for the future and pay owners at once. How that spending shapes the moat arithmetic appears in identifying competitive advantages through financial statements.

Where to take this next

Microsoft's 10-K rewards a reader who checks three places in order: the segment note for where the money comes from, unearned revenue for whether customers still pay in advance, and the capex line for what the future is costing.
