- Read the three statements together: the income statement shows what the company earns, the balance sheet what it owns and owes, and the cash flow statement where the money goes.
- Earnings quality divides operating cash flow by net income: Microsoft produced $1.37 of cash for every dollar of earnings in fiscal 2026.
- Separate what comes from the business from what comes from outside it: in fiscal 2026 Microsoft earned 31% more, but its operating income grew 20.8%.
- Rising earnings with falling free cash flow isn't bad news on its own, but it means you need to know what the money is being invested in.
- In 2017 and 2018, Kraft Heinz showed the classic red flags all at once: earnings without cash, a balance sheet full of intangibles and restated accounts.
Introduction
Microsoft closed fiscal 2026 on June 30, 2026, with net income of $133,749 million, up 31% from the year before. Perfect headline. But open its annual report and read the three financial statements together, and two other numbers show up: free cash flow fell for the second year in a row, to $66,987 million, and spending on data centers nearly doubled. Neither one is bad on its own. Missing them would be.
This lesson walks through an annual report from the first line to the last, with a real company, a case that went wrong and a list of questions you can use on any other company.
Explanation
Every year a company publishes three financial statements that tell the same story from three angles; the lesson on financial statements introduces them one by one. The income statement says how much the company sold and how much it earned. The balance sheet is a snapshot of what it owns and owes on the last day of the fiscal year. And the cash flow statement shows where the money actually came in and went out. Analyzing them doesn't mean calculating forty ratios. It means checking that the three versions fit together.
They're built to connect at three points. Net income from the income statement is the first line of the cash flow statement. Earnings that aren't paid out are added to equity on the balance sheet. And the cash at the end of the cash flow statement is the cash on the balance sheet. When earnings rise and cash doesn't follow, or when the balance sheet swells faster than the business, one of the three versions is telling an incomplete story.
Think of the books of a homeowners association. The minutes of the annual meeting say the year closed with a surplus: that's the income statement. The bank statement says how much money came in and went out: that's the cash flow. And the list of what the association owns and owes, the new elevator and the special assessment still pending, is the balance sheet. If the minutes brag about a surplus while the bank account is overdrawn, the property manager has some explaining to do.
Two ways to read the numbers
Horizontal analysis compares each line with the year before: how much sales, expenses or debt grew. Vertical analysis expresses each line as a percentage of a total: earnings over sales (the margins) or goodwill over total assets. You use both at once, and you'll see both in the walkthrough below.
The five-step method
1. Growth and margins: is the company selling more, and earning more on every dollar it sells?
2. Earnings quality: do earnings turn into cash?
3. Balance sheet: how much does it owe, how much cash does it hold and how much of its assets are intangibles?
4. Cash flows: does the cash go to investment, to paying down debt or to shareholders?
5. Red flags: is there anything that doesn't add up?
You'll need the annual report. In the United States that's the 10-K, which you can download free from EDGAR, the SEC's website. Outside the US, look for the annual financial report each listed company files with its market regulator. Keep the two prior years handy too: one year isn't a trend.
Formula
Earnings quality = Operating cash flow / Net income
Accruals = Net income − Operating cash flow (the part of earnings that isn't cash yet)
Free cash flow = Operating cash flow − Capital expenditure (capex)
Operating margin = Operating income / Revenue
Net debt = Financial debt − Cash and short-term investments
Goodwill weight = Goodwill / Total assets
Example
The table below shows the earnings quality of four large software companies, using Kaplio's data: Microsoft, Oracle, Adobe and Salesforce. Read it as dollars of operating cash for every dollar of net income. Above 1, earnings reach the bank with room to spare. Below 1 for a single year, no big deal; several years in a row, and you need to find out why.
Before you look: would you expect a company spending more than $100 billion a year on data centers to have earnings quality above or below 1? The answer is in step 2.
Full walkthrough: Microsoft, fiscal 2026 (ended June 30, 2026; 10-K, in millions of dollars)
Step 1. Growth and margins. Microsoft brought in $331,839 million in revenue in fiscal 2026, up 17.8% from $281,724 million in fiscal 2025. Operating income rose from 128,528 to $155,237 million, up 20.8%: faster than sales, so the operating margin improved from 45.6% to 46.8%. The gross margin, on the other hand, slipped: from 68.8% in fiscal 2025 to 67.9% in 2026, on $225,465 million of gross profit. Selling cloud computing capacity costs more than selling licenses, and that shows up near the top of the income statement; Microsoft made up for it further down, with expenses that grew more slowly than revenue.
Now net income: $133,749 million in fiscal 2026, up 31.3% from $101,832 million in 2025. Why did it grow faster than operating income? Because other income and expense, the line that doesn't come from the business, swung from subtracting $4,901 million in fiscal 2025 to adding $10,697 million in 2026, including $4,385 million of investment gains. Diluted EPS jumped from $13.64 to $17.95. To judge the business, stick with the 20.8% growth in operating income. The rest depends on investments that can reverse next year.
Step 2. Earnings quality. Microsoft's operating cash flow was $182,935 million in fiscal 2026. Divide it by net income: 182,935 / 133,749 = 1.37. It was 1.34 in fiscal 2025 and 1.35 in 2024. Microsoft generates more cash than it reports as earnings, and it does so consistently. The reasons are right there in the cash flow statement: $34,300 million of depreciation, which reduces earnings but not cash; $12,405 million of stock-based compensation, which doesn't come out of cash either; and customers who pay for their subscriptions in advance, with $75,712 million of deferred revenue at the end of fiscal 2026. And what customers owe? Receivables rose 15.7% in fiscal 2026, to $80,876 million: a little less than sales. Good sign: it isn't selling on credit to pump up the top line.
Keep an eye on stock-based compensation. It doesn't come out of cash, but it dilutes, and you pay that bill as a shareholder. You'll come back to it in step 4.
Step 3. Balance sheet. On June 30, 2026, Microsoft held $76,843 million in cash and short-term investments and $40,294 million in financial debt: net cash of $36,549 million. Goodwill, the premium it paid over book value in deals like Activision Blizzard, came to $119,651 million on that date: 15.8% of total assets of $758,376 million. At the end of fiscal 2026, current assets were $207,710 million and current liabilities 168,825: a current ratio of 1.23.
So far, a fortress balance sheet. But find the lease note. Microsoft rents a big share of its data centers under contracts that accounting treats as finance leases: $66,594 million at the end of fiscal 2026, against $46,172 million a year earlier, plus $21,925 million of operating leases. They don't show up as financial debt, but they're committed payments. Add just the finance leases and the $36,549 million of net cash becomes net debt of about $30 billion. That's still small next to $155,237 million of operating income in fiscal 2026, but it changes the picture.
Step 4. Cash flows: where the money goes. Capital expenditure was $115,948 million in fiscal 2026, against $64,551 million in 2025 and 44,477 in 2024. Free cash flow, operating cash flow minus capex, came to $66,987 million, below the 71,611 of fiscal 2025 and the 74,071 of 2024. Earnings up, free cash flow down: that's the bill for AI data centers. With that money, Microsoft paid $26,445 million in dividends and $22,271 million in share buybacks in fiscal 2026. Diluted shares barely moved: an average of 7,453 million in fiscal 2026 against 7,465 million in 2025. Buybacks, roughly speaking, offset the shares it hands out as compensation.
Step 5. Your verdict. No answer key here: apply the scorecard at the end of the lesson. One hint. The business is excellent and the balance sheet is solid. The open question is whether that $115,948 million of capex will earn as much as the dollars it invested before.

How to read it
How to read it
Rough ranges for reading each step; adjust them to the sector.
| Step | Healthy signal | Watch | Red flag |
|---|---|---|---|
| Growth | sales and operating income grow together | earnings grow only through cost cuts | sales falling for several years with shrinking margins |
| Earnings quality | operating cash flow / net income of 1 or more, stable | between 0.8 and 1 | below 0.8 for several years, or profits with negative operating cash flow |
| Receivables and inventory | grow in line with sales | somewhat faster | much faster than sales |
| Balance sheet | net cash, or debt within its sector's bar | close to the bar | high debt, with goodwill plus intangibles above half of total assets |
| Cash flows | free cash flow covers dividends and buybacks | covers them with debt for one year | pays for them with debt year after year |
The sector guide on Kaplio's stock pages tracks a close cousin of earnings quality, free cash flow over net income: healthy at 80% or more in general, 85% or more for industrials and 90% or more for pharma. None of this works the same way at banks and insurers: their operating cash flow mixes in deposits and loans.
Pitfalls and limitations
1. One year is nothing. A big acquisition, a catch-up tax payment or a shift in collection timing can move a single year's operating cash flow. Look at three to five years before you draw conclusions.
2. One-offs that keep happening. If a company books "non-recurring charges" every year, they're recurring. Be wary of adjusted earnings that always leave something out.
3. Operating cash flow can be dressed up too. Selling receivables to a bank, stretching payments to suppliers or classifying collections as investing activity can pull cash forward or shift it around. That's why the number isn't enough: you have to read the note.
4. Intangibles warn you late. Goodwill gets written down only when the company admits it overpaid, often years after the deal.
Case in point: Kraft Heinz, three flags at once
Kraft Heinz's 2017 accounts, as restated in its 2018 10-K, showed net income of $10,941 million. Its 2017 operating cash flow was $501 million: less than 5 cents of cash for every dollar of earnings.
The first flag was in taxes: the 2017 tax line was a benefit of $5,482 million, mainly because the tax reform passed in the United States in December 2017 cut the value of its deferred taxes. It was an accounting entry; not a single dollar came in. The second was in the cash flow statement: in 2017 it collected $2,286 million on receivables it had sold to a bank and booked that money under investing activities, and it contributed $1,659 million to its pension plans. Nothing illegal, but it forces you to read the notes. The third was on the balance sheet: at the end of 2017, goodwill ($44,825 million) and other intangibles, mostly brands ($59,432 million), added up to 86.8% of total assets of $120,092 million.
Brands are worth what they earn. In 2018, Kraft Heinz booked impairments of $15,936 million (7,008 on goodwill and 8,928 on brands and other intangibles) and ended the year with a net loss of $10,192 million. Its 2018 10-K wasn't filed in February, like the previous one, but on June 7, 2019, with prior years restated after an investigation into supplier rebates booked too early. The declared dividend per share fell from $2.50 in 2018 to $1.60 in 2019. In September 2021, the company agreed to pay a $62 million civil penalty to the SEC.
None of those signals, alone, screamed danger. Together they told a story: earnings that never reached the bank, a balance sheet built from brands bought at a steep price and accounts that arrived late. That's what you find when you read the three statements at once.
Self-assessment scorecard: ten questions for any 10-K
1. Have sales and operating income grown together over the last three to five years?
2. Is the operating margin rising, holding or shrinking, and can you explain why?
3. How much of net income comes from outside the business: other income, taxes, asset sales?
4. Does operating cash flow consistently exceed net income?
5. Are receivables and inventory growing faster than sales?
6. How much net debt is there, with and without leases, and how does it compare with its sector's bar?
7. How much of total assets is goodwill and intangibles?
8. Does free cash flow cover dividends and buybacks, or are they paid for with debt?
9. Is the share count really falling, or do buybacks just offset stock-based compensation?
10. Has the company filed late, changed auditors or restated its accounts?

Frequently asked questions
What is the purpose of financial statement analysis?
To find out whether a business earns money sustainably, whether those earnings turn into cash, whether it can pay what it owes and what it spends its cash on. For an investor, it helps decide whether a company deserves a deeper look, and it surfaces the early signs that something doesn't add up.
What is horizontal and vertical analysis of financial statements?
Horizontal analysis compares each line with prior years: Microsoft's revenue grew 17.8% in fiscal 2026. Vertical analysis expresses each line as a percentage of a total: its operating margin was 46.8% of revenue. The first shows the trend; the second, the structure. You use the two together, never one alone.
What are the 3 financial statements and how are they connected?
The income statement measures what the company earns, the balance sheet shows what it owns and owes, and the cash flow statement tracks the cash that actually comes in and goes out. Net income is the first line of the cash flow statement, retained earnings feed equity, and ending cash matches the balance sheet.
