How Do Unusual Items Influence Profit?

Importantly, our data indicates that LUSTER LightTech's profit received a boost of CN¥35m in unusual items, over the last year. 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 that's as you'd expect, given these boosts are described as 'unusual'. LUSTER LightTech had a rather significant contribution from unusual items relative to its profit to September 2024. As a result, we can surmise that the unusual items are making its statutory profit significantly stronger than it would otherwise be.

An Unusual Tax Situation

Having already discussed the impact of the unusual items, we should also note that LUSTER LightTech received a tax benefit of CN¥22m. This is meaningful because companies usually pay tax rather than receive tax benefits. Of course, prima facie it's great to receive a tax benefit. However, our data indicates that tax benefits can temporarily boost statutory profit in the year it is booked, but subsequently profit may fall back. Assuming the tax benefit is not repeated every year, we could see its profitability drop noticeably, all else being equal. While we think it's good that the company has booked a tax benefit, it does mean that there's every chance the statutory profit will come in a lot higher than it would be if the income was adjusted for one-off factors.

Our Take On LUSTER LightTech's Profit Performance

In the last year LUSTER LightTech received a tax benefit, which boosted its profit in a way that might not be much more sustainable than turning prime farmland into gas fields. Furthermore, it also benefitted from a positive unusual item, which boosted the profit result even higher. For all the reasons mentioned above, we think that, at a glance, LUSTER LightTech's statutory profits could be considered to be low quality, because they are likely to give investors an overly positive impression of the company. In light of this, if you'd like to do more analysis on the company, it's vital to be informed of the risks involved.
