Read a business
Connect the business model to revenue, margins, cash, debt, and reinvestment.
After this module
You can turn financial statements into a small set of drivers and red flags rather than a ratio checklist.
Business engine
Revenue → Profit → Cash
How the company makes money
Start with customers, the problem solved, pricing, recurring behavior, costs, and competitive alternatives.
- Identify the unit sold and who pays.
- Separate volume growth from price increases and acquisitions.
- Ask why customers stay and what could make them leave.
Example
Subscription revenue may be recurring, but only if retention is strong and customer acquisition remains economic.
Three statements, one story
The income statement measures performance, the balance sheet shows resources and obligations, and the cash-flow statement reconciles accounting profit with cash.
- Compare revenue growth with receivables and cash collection.
- Distinguish operating cash flow from free cash flow after investment.
- Check debt maturities, interest burden, dilution, and off-balance-sheet commitments.
Example
Profit rising while cash falls and receivables surge deserves investigation, not an automatic conclusion.
Common trap
EBITDA is not cash and excludes real claims such as capital expenditure, interest, and taxes.
Quality and reinvestment
Long-term value creation depends on how much capital can be reinvested and the return earned on it.
- Look for attractive returns on incremental capital.
- Check whether growth requires heavy dilution or debt.
- Separate temporary margin pressure from deteriorating unit economics.
Example
A company can grow revenue quickly while destroying value if each new customer costs more than the cash they generate.
Red-flag language
Certain patterns deserve follow-up: repeated ‘one-off’ charges, adjusted metrics without reconciliation, auditor changes, related-party transactions, and guidance changes without clear drivers.
- Read risk factors and footnotes, not only the presentation.
- Compare management’s prior promises with subsequent outcomes.
- Treat short-seller or promotional claims as leads to verify, not conclusions.
Try it yourself · no real money
Trace the business engine
Adjust reported growth across the income statement and cash flow. The gaps tell you where to investigate, not what to conclude automatically.
Pattern to investigate
The three measures broadly agree
One metric is a clue. The relationship between metrics is the story.
Primary-source reading lab
Turn a financial record into a better question
Read a compact, fictionalized company record. Separate what the numbers establish from what still needs evidence.
Revenue: 1,200 → 1,440 (+20%) · Operating profit: 180 → 194 (+8%)
What is the most useful first interpretation?
Reading discipline
Observation → interpretation → follow-up
First state what changed. Then describe a plausible interpretation without treating it as certainty. End with the next source or metric that could confirm it.
Knowledge check
Revenue grows 30%, but receivables grow 90% and operating cash flow falls. What is the best response?
