Level 6 · Annual Report Analysis
Segment Reporting
One company, several businesses, and only one may be earning the money.
In this lesson
What you'll be able to do
- Read a segment table
- Compute segment margins
- Identify loss-making segments
- Use segments to understand conglomerates
Think about it
A conglomerate reports 12% overall margin. Its four businesses run at 30%, 8%, 2% and −9%. Which number would you rather know?
Story
Let's picture it
A family runs a restaurant, a bakery and a catering van under one name. The combined books look modestly profitable. Break it apart and the bakery is thriving, the restaurant is breaking even, and the catering van has lost money for three years. The combined number described none of them.

Working through a segment table
Segment revenue
Sales attributable to each business line
Segment results
Profit contributed before unallocated items
Segment margin
Result ÷ revenue for each, compute it yourself
Segment assets
Capital tied up in each, revealing returns by business
Plain English
The simple explanation
Accounting standards require companies with distinct business lines to disclose revenue, results and assets by segment, and often by geography as well.
Compute margins for each segment yourself. The table gives revenue and result; the ratio between them is where the insight lives.
Compare segment assets with segment results too. A business consuming a third of the capital while producing a tenth of the profit is a genuine strategic question, however good the consolidated numbers look.
Real world
Indian conglomerates
Large diversified Indian groups report segments such as energy, retail and digital services. Consolidated profit alone tells a student nothing about which engine is driving results, the segment table tells them everything.
Watch out
Common mistakes
- Relying only on consolidated figures.
- Not calculating segment margins.
- Ignoring how much capital each segment uses.
Did you know?
Geographical segment disclosure often reveals concentration risk the business-line table hides, for example most profit coming from a single export market.
