Revenue, earnings, and what sits between
Revenue is the top line; earnings are what survives after costs, interest, and tax. The path between them is the story.
Walking down the income statement
Start with revenue. Subtract cost of goods sold to get gross profit — the money left to run the company. Subtract operating expenses such as research, sales, and administration to get operating income, the profit from the actual business. Then subtract interest and tax to reach net income.
Each step answers a different question: Is the product profitable? Is the company profitable? Is the capital structure sustainable?
Earnings per share
EPS is net income divided by shares outstanding. It can rise because profit grew or because the share count shrank through buybacks. Those are very different facts wearing the same clothes, so check both numbers.
One-off items
Asset sales, restructuring charges, and legal settlements distort a single period. Read several years and separate recurring operating performance from noise before drawing a trend.
Worked example
Growing EPS without growing profit
- Year 1: net income $100m, 50m shares. EPS = $2.00.
- Year 2: net income $100m (flat), but buybacks cut the count to 44m shares.
- EPS = $100m / 44m = $2.27, an apparent 13.5% increase.
- The business earned no more money than last year.
Always read EPS growth alongside net income growth and the share count. Per-share arithmetic can flatter a flat business.
Common misconceptions
“Revenue growth means the company is doing well.”
Revenue bought with collapsing margins or heavy discounting can destroy value while the top line climbs.
“A company that beat EPS estimates had a good quarter.”
Beats can come from buybacks, tax items, or lowered expectations rather than operating strength.
