How to read an earnings report

8 min read

Every quarter (every six months for most UK companies), listed companies report how the business performed. Earnings season moves individual stocks more than almost anything else, and reading a report well is the foundation for everything that follows in this track.

What gets published

  • The press release: headline numbers, management commentary and usually guidance. Out before the market opens or after it closes.
  • The earnings call: management talks through results, then analysts ask questions. The Q&A is often where the real information is.
  • The filing: the full accounts and notes (a 10-Q or 10-K in the US, interim or annual results in the UK). Slower to read, harder to spin.
  • Slides and supplements: segment breakdowns and the KPIs the company wants you to focus on.

Revenue is everything sold. Subtract the direct cost of making it and you get gross profit, which shows pricing power. Subtract running costs and you get operating income, the profit of the core business. After interest and tax you reach net income. Divide it by the share count and you get earnings per share (EPS), the subject of the next lesson.

The order to read it in

  1. Headline vs expectations. Revenue and EPS against the analyst consensus. A “beat” or “miss” is always relative to what was expected, not to last year.
  2. Guidance. What management expects next quarter and next year. Markets price the future, so guidance usually matters more than the quarter just reported.
  3. Quality of the beat. Did EPS beat because sales were strong, or because of a lower tax rate, a one-off gain or cost cuts that can’t be repeated?
  4. Margins. Gross and operating margin trends show whether the business is gaining or losing pricing power.
  5. Segments and KPIs. Which parts of the business are driving growth. For a software company that might be customer numbers, for a retailer like-for-like sales.
  6. Cash flow. Did profit turn into cash? Free cash flow (operating cash flow minus capital expenditure) is harder to flatter than earnings.
  7. Balance sheet. Cash, debt and anything that changed sharply, like inventory piling up or receivables growing faster than sales.

Adjusted vs reported

Companies often lead with “adjusted” figures that strip out items like restructuring costs or share-based pay. Some adjustments are reasonable. Others flatter the business every single quarter. Always check the gap between adjusted and reported (GAAP or IFRS) profit, and whether it is growing.

Why shares react the way they do

A company can beat on every line and still fall 10% if the market was expecting more, sometimes called the “whisper number”. The best reactions usually come from a beat and raise: better results and higher guidance. The worst from a miss with lowered guidance, because it suggests the problem isn’t one quarter.

Key takeaway

Read expectations first, guidance second and the quality of the numbers third. The headline tells you what happened. The rest tells you whether it lasts.
