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 Amentum Holdings Inc. (AMTM). It shows which part of the business is growing — and which one is holding it back.

Remaining performance obligations
Remaining performance obligations are the part of the business already sold but not yet delivered and therefore not yet booked as revenue. In subscription and project businesses it points the way earlier than revenue does.
