Financial statements I: the income statement

The page, top to bottom

The income statement covers a period — a quarter, a year — and it is built as a waterfall: money comes in at the top and is spent, line by line, until what remains is the profit. Revenue is the top line: everything the company sold, before any cost. Subtract the cost of goods sold — the direct cost of making what it sold — and you get gross profit. Subtract the operating expenses (the staff, the rent, the research, the marketing — the cost of running the company, as opposed to making its product) and you get operating income: the profit of the business itself. Then the financing lines — interest paid, taxes owed — and what survives to the bottom line is net income.

Divide the earnings that belong to the common shareholders by the share count — precisely, the weighted-average shares outstanding across the period, not the count on any single day — and you have earnings per share (Lesson 8’s EPS), the number the whole market quotes. It comes in two honest flavors: basic EPS, on the shares that actually existed, and diluted EPS, which also counts the shares that would appear if in-the-money options and convertible securities were exercised. The diluted figure is the conservative one, and it is usually the one quoted. One subtraction comes before the division, and the definition of EPS carries it: if the company has preferred shares, their dividends are paid out of net income first, and EPS is computed on what remains — the income available to common shareholders. A company with no preferred stock skips the step, but no reader of a filing should skip knowing it: EPS is the common shareholder’s slice of the profit, per share, after every claim ahead of theirs. But EPS is the end of the story this page tells. The story is in the margins — the next section.

Margins are the story

A margin is any line of the waterfall expressed as a percent of revenue — and margins, not totals, are how businesses are compared. Gross margin (gross profit ÷ revenue) measures the product’s own economics: what the thing sells for versus what the thing costs to make. Operating margin adds the running costs: the whole operation’s discipline. Net margin is what a dollar of sales is finally worth to the owners. Two companies can post identical revenue growth and be opposite businesses — one expanding its margins (each new dollar is worth more than the last), one buying growth by surrendering them.

Margins also police Lesson 8’s valuation. A high P/E multiple is, in part, a bet that margins can expand or hold at heights history says are rare; a low one often prices margins already in retreat. The multiple also comes in the two tenses Lesson 8 uses, and this page supplies both: a trailing P/E divides the price by the EPS already reported — the filed history on this page — while a forward P/E divides by the EPS analysts expect next, a forecast rather than a filing. Same letters, different evidence, and a reader should always know which tense a quoted multiple is speaking. When the journal’s fundamentals work quotes margins (it does, every day, in the same formulas for every name), this page is where those numbers are born.

Reading one like an owner

Read the waterfall in the order an owner feels it. Revenue first: is the company actually selling more, and is the growth speeding up or slowing (Folder 2’s sectors give the weather every company sells into)? Then gross margin: is the product getting more or less profitable per unit — the raw material of a pricing-power story, though one ratio, in one period, never proves one. Then the operating lines: are the running costs growing faster than revenue (a young company investing, or an old one bloating — the trend decides which), and is operating income keeping its share?

Two cautions keep the reading honest. One-time items — a factory sold, a lawsuit settled, a write-down — can inflate or crater a single quarter’s lines; owners read through them to the recurring business, and filings are required to show them separately enough to do so. And a single quarter is a single frame: the income statement rewards the reader who lines four of them up and reads the direction of the margins, not the level of one print.

Where this page ends

The income statement has a known blind spot, and the next lesson exists because of it: it records revenue when it is earned and costs when they are incurred, which is not always when cash moves. A company can report a profitable quarter and be quietly running out of money — the statement of the business’s performance is not the statement of its cash. Profitable and broke is a real combination, and the balance sheet plus the cash flow statement are the two pages that catch it.

Hold this page’s skill, though — it is the first half of owning the fundamentals the way this journal uses them: revenue, the waterfall, the margins, the trend. The second half is next, and it finishes the sentence: the company earned this much — and here is what it owns, owes, and actually collected.

Where this breaks

One period’s margins certify nothing — a cheap input year, a shifted product mix, or costs deferred past the period’s end can all print a handsome margin once. The multi-year trend in this lesson’s worked example is evidence consistent with pricing power; it is still not proof, because margins never say what would have happened at different prices. The caution runs both ways: a falling margin can be a deliberate price cut buying share, not a business decaying.

Practice

Interpret a fictional statement, two years of it. Meridian Industrial reports: revenue $45.1B then $48.0B; gross profit $16.6B then $18.2B; net income $4.06B then $4.7B; preferred dividends $0.2B in both years; weighted-average shares 1.9B in both years. (1) Gross margin and net margin, both years. (2) Year two’s earnings per share, on the numerator that belongs to common shareholders. (3) In one sentence: what the margin trend is consistent with — and the reason it still is not proof.

Answers: (1) Gross: 36.8% then 37.9%. Net: 9.0% then 9.8%. (2) ($4.7B − $0.2B) ÷ 1.9B = about $2.37 — the preferred slice comes off before the common shareholders’ earnings are divided. (3) The widening trend is consistent with pricing power; it is not proof, because two margins cannot show what would have happened at different prices, or what was deferred to print them.
