Segments
US companies must disclose in their mandatory reports how revenue breaks down across business segments, regions and product lines. We read that breakdown for you straight from the annual and quarterly reports (10-K and 10-Q) of Constellation Energy Corp (CEG). It shows which part of the business is growing — and which one is holding it back.
