Operating Segment
A reportable component of a company whose financial results are reviewed separately by management.
What is Operating Segment?
An operating segment is a component of a business that engages in activities from which it may earn revenues and incur expenses, whose operating results are regularly reviewed by the chief operating decision maker to allocate resources and assess performance. Under ASC 280 (Segment Reporting) and IFRS 8, a company must disclose segment-level financial information for any segment that represents 10% or more of consolidated revenues, profit, or assets. These disclosures help investors understand the composition of a diversified company's operations and identify where profits and growth are concentrated. Segments may be defined by product line, geography, customer type, or business model.
Example
Apple Inc. reports five reportable operating segments in its annual filings: iPhone, Mac, iPad, Wearables/Home/Accessories, and Services. In FY2024, the Services segment generated $96.2 billion in revenue with significantly higher gross margins than hardware segments, providing investors with meaningful insight into Apple's strategic shift toward recurring subscription revenue.
