Segment Reporting
Disclosure of a company's financial performance broken down by distinct business units or geographic regions.
What is Segment Reporting?
Segment reporting requires public companies to disclose financial results for each reportable operating segment — a distinct component of the business that earns revenue, incurs expenses, and whose results are regularly reviewed by management. Under GAAP (ASC 280) and IFRS 8, a segment is reportable if its revenue, profit, or assets represent at least 10% of consolidated totals. Segment data helps investors evaluate which parts of a business are growing or declining, compare profit margins across divisions, and build more precise valuation models. Companies have significant discretion in defining segments, so changes in segment structure — often coinciding with management changes — can affect comparability.
Example
Apple reports four product and service segments: iPhone, Mac, iPad, Wearables/Accessories, and Services. The Services segment — including the App Store, Apple Music, and iCloud — has become analysts' most valued segment due to its high margins and recurring revenue, despite representing less than 25% of total revenue.
