How Do Unusual Items Influence Profit?

To properly understand Martin Marietta Materials' profit results, we need to consider the US$1.3b gain attributed to unusual items. We can't deny that higher profits generally leave us optimistic, but we'd prefer it if the profit were to be sustainable. When we crunched the numbers on thousands of publicly listed companies, we found that a boost from unusual items in a given year is often not repeated the next year. And, after all, that's exactly what the accounting terminology implies. We can see that Martin Marietta Materials' positive unusual items were quite significant relative to its profit in the year to March 2024. All else being equal, this would likely have the effect of making the statutory profit a poor guide to underlying earnings power.
