What you will learn
- Explain how the three statements interlock into one system
- Follow a repeatable process to tear down a company end to end
- Combine the four ratio lenses into a single evidence-based verdict
- See how understanding a company sets up valuing it in Unit 3
This capstone is where mechanics become judgment. You now know each statement, each ratio, and each red flag on its own. Real analysis weaves them into one coherent verdict on a business. The goal is not to compute numbers for their own sake but to tell an evidence-based story about how a company makes money, how strong it is, and where it might be heading. This is the skill the whole unit has been building toward.
Financial ratios: how to analyze financial statements (Accounting Stuff)
Ties the key ratios together into an analysis of a company. A great model for the teardown process you are about to learn.
The statements are one system, not three
The most important realization in this whole unit is that the three statements interlock. Net income from the income statement flows into retained earnings on the balance sheet and is the starting point of the cash flow statement. Capital expenditures on the cash flow statement reduce cash and build up property and equipment on the balance sheet. A change in receivables on the balance sheet shows up as a cash adjustment in operating cash flow. Pull one thread and the others move. A skilled analyst reads them together, cross-checking each against the others.
Key terms
- Teardown
- A full, end-to-end analysis of a company built from its financial statements.
- Thesis
- A clear, reasoned verdict on a company's strengths, weaknesses, and risks, supported by evidence.
- The four lenses
- Profitability, efficiency, leverage, and liquidity, the ratio families that together judge a company.
| This item... | On this statement... | Connects to... |
|---|---|---|
| Net income | Income statement | Retained earnings on the balance sheet |
| Capital expenditure | Cash flow statement | PP&E on the balance sheet |
| A rise in receivables | Balance sheet | A cash subtraction in operating cash flow |
| Ending cash | Cash flow statement | The cash line on the balance sheet |

A repeatable teardown process
- Start with the 10-K. Understand what the business actually does and how it makes money before touching a single ratio.
- Analyze the income statement. Is revenue growing, and are the margins (gross, operating, net) stable, expanding, or eroding?
- Examine the balance sheet. How much leverage (debt-to-equity) does it carry, and is its liquidity (current and quick ratios) sound?
- Scrutinize the cash flow statement. Does operating cash flow support reported profit, and is free cash flow positive or heading there?
- Compute the key ratios across the four lenses, profitability (margins, ROE, ROA), efficiency, leverage, and liquidity, and compare them to peers and history.
- Run a quality-of-earnings check. Do receivables, inventory, or repeated one-time items raise any flags?
- Use common-size statements and multiples to benchmark the company against its competitors and the market.
Anyone can read a number. An analyst connects the numbers into a story, and then asks whether the market's price agrees with it.

Read the whole picture
A company shows rising revenue and rising net income. But its operating cash flow is falling, its receivables are ballooning, its debt-to-equity has climbed to 3, and its current ratio has dropped below 1. What is the honest verdict?
Reading the statements together reveals that strong headline growth sits on falling cash conversion, rising leverage, and weak liquidity. The teardown turns scattered numbers into one honest verdict.From numbers to narrative
The output of a teardown is a thesis, not a spreadsheet. It is a clear statement of what makes this company strong or fragile, what its statements reveal that the headlines do not, and what risks could change the picture. The numbers are evidence in service of that argument. Two analysts can look at the same statements and reach different conclusions. What separates good analysis is rigor, skepticism, and a willingness to let the evidence, not the hype, lead.
The bridge to valuation
Understanding a company is the prerequisite to valuing one. Everything you have built here, reading the statements, judging earnings quality, comparing efficiency and risk, feeds directly into Unit 3, where you will estimate what a business is actually worth and compare that to its market price. Remember from Unit 1 that a great company can be a poor investment at the wrong price, and a mediocre one a fine investment at the right price. Fundamental analysis tells you which is which, and it begins with the teardown you can now perform.
Your first teardown
Pick a company and sketch a mini teardown in a short paragraph. Note one thing you would check on each statement, one ratio from each of the four lenses, and the one earnings-quality test you would run. You do not need real numbers, just the plan.
Write an answer before comparing it with the model response.
Model answer
A strong answer names a check on each statement (revenue growth and margins on the income statement, leverage and liquidity on the balance sheet, whether operating cash flow supports profit on the cash flow statement), one ratio per lens (a margin for profitability, ROE or ROA for efficiency, debt-to-equity for leverage, the current ratio for liquidity), and the net-income-versus-operating-cash-flow cross-check for earnings quality. The point is a repeatable plan that reads the statements as one connected system.
That completes Unit 2. You can now read the three statements, compute the ratios that matter, judge whether earnings are trustworthy, and pull it all into an evidence-based verdict on a business. In Unit 3 you take the next step, from understanding a company to putting a value on it.
