Investors were disappointed with the weak earnings posted by Corning Incorporated (NYSE:GLW ). Despite the soft profit numbers, our analysis has optimistic about the overall quality of the income statement.

The Impact Of Unusual Items On Profit

Importantly, our data indicates that Corning's profit was reduced by US$593m, due to unusual items, over the last year. It's never great to see unusual items costing the company profits, but on the upside, things might improve sooner rather than later. We looked at thousands of listed companies and found that unusual items are very often one-off in nature. And, after all, that's exactly what the accounting terminology implies. Corning took a rather significant hit from unusual items in the year to June 2024. All else being equal, this would likely have the effect of making the statutory profit look worse than its underlying earnings power.

That might leave you wondering what analysts are forecasting in terms of future profitability. Luckily, you can click here to see an interactive graph depicting future profitability, based on their estimates.

Our Take On Corning's Profit Performance

As we discussed above, we think the significant unusual expense will make Corning's statutory profit lower than it would otherwise have been. Based on this observation, we consider it possible that Corning's statutory profit actually understates its earnings potential! Unfortunately, though, its earnings per share actually fell back over the last year. At the end of the day, it's essential to consider more than just the factors above, if you want to understand the company properly. So while earnings quality is important, it's equally important to consider the risks facing Corning at this point in time.
