Financial statement analysis
The statements tell you what happened. Analysis tells you why, and whether it continues.
Read the three statements against each other
A single statement is almost never enough. The income statement reports profit, the cash flow statement reports cash, and the gap between them is usually the story.
- Net income rising while operating cash flow falls is the signal worth chasing first. It means working capital is absorbing the growth, or revenue is being recognized ahead of collection.
- The balance sheet is a point in time; the other two cover a period. Comparing a period figure to a point-in-time balance without averaging the balance overstates efficiency ratios.
- Read the notes. Concentration of customers, debt maturities, commitments, related parties, and subsequent events routinely matter more than anything on the face of the statements.
Do fluctuation analysis before you compute a single ratio
Compare against the prior period and against budget. They answer different questions: prior period tells you what changed, budget tells you whether you understood your own business.
- Set a threshold in both currency and percent. Percent alone sends you chasing large swings on small accounts; currency alone hides a small account that doubled.
- Explain with a driver, not a restatement. "Revenue up 12%" is the observation, not the explanation. Volume, price, mix, timing, and one-off items are explanations.
- Track how many variances you cannot explain. A close where three material movements have no owner is telling you something about the underlying records, not about performance.
Compute ratios against the question you actually have
- Profitability — gross margin, operating margin, net margin, return on invested capital.
- Liquidity — current and quick ratio, and the one that usually matters more in practice, days of cash on hand.
- Leverage and solvency — debt to EBITDA, interest coverage, debt to equity.
- Efficiency — days sales outstanding, days payable outstanding, days inventory outstanding, and the cash conversion cycle they combine into.
Ratios are comparative instruments. One ratio at one date means close to nothing; the trend across periods and the comparison to peers are where the information is.
Benchmark within industry and roughly within scale
Gross margin compared across industries is noise. So is comparing a company at $5M to one at $500M on cost structure — the second has fixed costs the first cannot carry and buying power the first cannot access.
Internal benchmarking across segments, regions, or product lines is often more useful than external comparison, because the accounting policies are already consistent.
Test non-GAAP measures before you repeat them
EBITDA, adjusted EBITDA, free cash flow, core earnings, adjusted net income, annual recurring revenue. These exist for a real reason — statutory profit includes items that obscure operating performance — and also because management chooses the adjustments.
- Ask what was added back, and whether it recurs. A restructuring charge that appears every year is an operating expense wearing a different label.
- Ask whether the adjustment would survive good results. Adjustments that only appear in bad quarters are presentation, not measurement.
- Reconcile to the nearest statutory measure and show the reconciliation. A number that cannot be tied back is not a measure, it is an assertion.
Diagnosing a deteriorating trend
Work from the top down and stop at the first level that explains it. Revenue, then gross margin, then operating expense, then working capital, then financing cost. Most deterioration that looks like a demand problem is a margin or working capital problem, and the two call for different responses.

references/sources.md in this skill lists the outside authorities that settle the questions
here — what each one is authoritative for, and what you may do with it. Check them before
answering on anything they cover, and cite what you used. Most are free to read and not free
to reproduce; the use note on each is binding.
Never
- Present a ratio with no trend and no comparison. A number standing alone is decoration.
- Explain a variance by restating it in different words.
- Repeat an adjusted measure without seeing what was added back.
- Annualize a partial period without saying you did, or apply a seasonal quarter as a run rate.
