1. Surging Backlog Locks In Future Sales
In addition to reported revenue, backlog is a useful data point for analyzing Heavy Transportation Equipment companies. This metric shows the value of outstanding orders that have not yet been executed or delivered, giving visibility into Federal Signal’s future revenue streams.
Federal Signal’s backlog punched in at $997.1 million in the latest quarter, and over the last two years, its year-on-year growth averaged 14.4%. This performance was fantastic and shows the company has a robust sales pipeline because it is accumulating more orders than it can fulfill. Its growth also suggests that customers are committing to Federal Signal for the long term, enhancing the business’s predictability.
