Even though Rastar Group (SZSE:300043 ) posted strong earnings, investors appeared to be underwhelmed. We did some digging and actually think they are being unnecessarily pessimistic.

How Do Unusual Items Influence Profit?

Importantly, our data indicates that Rastar Group's profit was reduced by CN¥16m, 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. When we analysed the vast majority of listed companies worldwide, we found that significant unusual items are often not repeated. And that's hardly a surprise given these line items are considered unusual. Rastar Group took a rather significant hit from unusual items in the year to December 2023. All else being equal, this would likely have the effect of making the statutory profit look worse than its underlying earnings power.

An Unusual Tax Situation

Just as we noted the unusual items, we must inform you that Rastar Group received a tax benefit which contributed CN¥21m to the bottom line. It's always a bit noteworthy when a company is paid by the tax man, rather than paying the tax man. Of course, prima facie it's great to receive a tax benefit. And since it previously lost money, it may well simply indicate the realisation of past tax losses. 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.

Our Take On Rastar Group's Profit Performance

In the last year Rastar Group 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. But on the other hand, it also saw an unusual item depress its profit. After taking into account all these factors, we think that Rastar Group's statutory results are a decent reflection of its underlying earnings power.
