🔎How to "read" a company in 10 minutes: fundamentals for absolute beginners

The first time you look at a company's financial statements, it can feel like reading a foreign language. The good news: to get a solid basic orientation, you only need a handful of numbers. This week we'll show you how to "read" a company in about ten minutes — no formula-packed spreadsheets, just common sense and a few key concepts.

Think of a company as a living organism. You want to know three basic things: How big is it and is it growing? Does it earn real cash, or just "paper" profit? Is it not so indebted that one bad year could sink it? Five indicators answer these questions.

1. Revenue — how much the company sells

Revenue is the total amount a company earns from selling its products or services, before subtracting any costs. It's similar to your gross salary before taxes and deductions.

• Why it matters: Growing revenue shows increasing demand for the company's product.
• Watch out for: Revenue that stagnates or declines year after year is a warning sign — even if the company looks "cheap" by other metrics.

Example: If a company like Coca-Cola (KO) reported revenue of $46 billion last year and $44 billion this year, that's roughly a 4% decline. That alone isn't necessarily a disaster, but it's a question worth asking — why?

2. Profit and margin — how much of revenue actually stays with the company

Net income is what remains after all costs, interest, and taxes are paid. Margin expresses profit as a percentage of revenue — essentially "how much of each dollar of revenue the company actually keeps."

• Gross margin = what's left after direct production costs.
• Operating margin = what's left after regular operating costs too (wages, marketing, rent).
• Net margin = what's left at the very end, after interest and taxes.

Analogy: You run a lemonade stand. Revenue is everything you collect from customers. Margin is what stays in your pocket after paying for lemons, sugar, cups, and rent for your spot. A company with a high margin (e.g., a software company with a 30% margin) can afford more mistakes than a company with a 3% margin (typical for some retailers or shippers), where even a small hiccup can push it into a loss.

3. Free cash flow (FCF) — real cash, not just an accounting figure

Accounting profit can be legally "improved" through various non-cash methods (depreciation, accruals, etc.). That's why experienced investors also watch free cash flow — the cash that actually remains after operating costs and investments in equipment, buildings, and technology.

• Why it matters: A company with positive and growing FCF can afford to pay dividends, buy back shares, pay down debt, or invest in growth — without needing to borrow.
• Warning sign: A company that consistently reports accounting profit but negative free cash flow deserves a closer look — sometimes it means the "profit" is largely on paper only.

4. Debt — how much the company owes and can it repay it?

Companies commonly borrow to fund investments — that's not inherently bad. The question is whether the debt is proportional to the company's size and earning power.
