Reading a company: five numbers every student should understand · Pulse Beat

When a company appears in the news, the commentary is full of numbers: revenue, profit, margins, valuation. It all becomes less intimidating if you learn to read the same handful of figures in the same order.

This is general education, not investment advice. It explains how to read basic financial information, not what to buy or sell.

1. Revenue: how much money comes in

Revenue, also called sales or turnover, is the total money a company earns from selling its products or services before subtracting any costs. It answers: how big is the business?

Two things matter more than the number itself.

Growth. Is revenue rising, flat or falling compared with last year? A growing company may be winning customers; a shrinking one may be losing ground.
Quality. Does it come from many customers or from one big one? Is it repeating, like subscriptions, or one-off? Repeating revenue is generally easier to predict.

2. Profit: what is left

Profit is revenue minus costs, but there are several kinds, and news stories mix them up.

Gross profit: revenue minus the direct cost of making or delivering the product. It shows how much each sale leaves before overheads.
Operating profit: gross profit minus running costs such as salaries, rent and marketing. It shows how well the core business works.
Net profit: what remains after everything, including interest and taxes. This is the bottom line.

A company can have growing revenue and still make a loss. That is common in young businesses spending heavily to grow, and it is not automatically bad, as long as there is a credible path to profit and enough money to get there.

3. Margin: profit as a share of sales

A margin expresses profit as a percentage of revenue. If a company earns one hundred rupees in sales and keeps ten after all costs, its net margin is ten percent.

Margins let you compare companies of different sizes and watch a single business over time. A supermarket may live happily on thin margins with huge volume; a software company may have very high margins because copying software costs little. Comparing a company with others in the same industry is far more meaningful than comparing across industries.

4. Cash flow: money actually moving

Profit is an accounting measure; cash flow is the real movement of money in and out of the bank. A company can show a profit while running out of cash, for instance if customers pay late or it spends heavily on equipment. Many failures happen not because a business was unprofitable on paper but because it ran out of cash.

Read the cash flow in three parts: from operations (the day-to-day business), from investing (buying or selling equipment and other businesses) and from financing (raising or repaying loans and shares). Healthy established companies usually generate cash from operations.

5. Debt: what is owed

A company that borrows can grow faster, but it must repay with interest, even when business is poor. Look at how much debt there is compared with the company's earnings and assets, and whether profits comfortably cover the interest.

A simple test is the interest cover: operating profit divided by interest paid. A large number means comfort; a number near one means little margin for error.

What about valuation?

Valuation measures what the market thinks the company is worth, such as its total market value, called market capitalisation: the share price times the number of shares. A ratio you will hear is the price-to-earnings (P/E) ratio, the share price divided by profit per share. A high P/E means investors expect strong growth, or are paying a high price; a low one may signal low expectations or a bargain. No number is good or bad on its own; the context of growth, risk and industry matters.

An important warning: a price in the market is a moving opinion, not a fact about the business.

Where to find the numbers

Listed companies publish regular financial results, and annual reports contain statements of income (profit), balance sheet (what is owned and owed) and cash flow. Regulators and exchanges have public filings. Read the management's discussion section for the story behind the numbers, and read the notes for the cautions.

Common traps for beginners

Reading only the headline number. Always check the trend and what is excluded.
Ignoring one-off items. A single big sale of an asset can make profit look unusually good.
Comparing across industries. A margin that is excellent in one sector is poor in another.
Believing a confident story. Forecasts are guesses.
Following tips from social media without understanding the numbers yourself.

A practice exercise

Choose a company whose products you use. Find its latest annual results. Write down revenue and how it changed, net profit and margin, cash from operations, and total debt. Then write three sentences in your own words: how is the business doing, what worries you, and what would you want to know next? Doing this a few times teaches more than reading any number of commentaries.

Understanding these five figures will not tell you what a share price will do. It will, however, let you read the news with your own judgement instead of someone else's excitement.
