intersegment revenue

Revenue generated from sales made by one operating segment of a company to another segment within the same company.

Intersegment revenue represents the value of goods or services transferred internally between different operating divisions or business units of the same parent corporation. While these transactions are recorded in individual segment reports to measure divisional performance and resource allocation, they are eliminated during the consolidation process. Consequently, they do not appear on the company's final consolidated income statement, which only displays transactions with external customers. For investors, analyzing intersegment revenue is vital to understanding how self-sufficient a business unit is. If a segment boasts massive revenue growth but the majority of it is intersegment, the business unit is highly dependent on internal corporate demand rather than external market validation. This distinction helps investors assess the true commercial viability and competitive positioning of a company's individual business lines. When evaluating diversified companies or vertically integrated businesses, a high proportion of intersegment revenue can sometimes mask a division's vulnerability to internal corporate changes. If the parent company decides to source those services externally or downsize the buying division, the selling division's revenue could collapse. Investors should look at segment disclosures in the footnotes of 10-K and 10-Q filings to separate internal transfers from external customer sales.

Company A's manufacturing division reports total segment revenue of $10,000,000. However, $4,000,000 of this total represents components sold internally to Company A's consumer products division. The external segment revenue is therefore $10,000,000 - $4,000,000 = $6,000,000, showing that 40% of the manufacturing division's business relies on internal demand.
