A lackluster earnings announcement from Sansec Technology Co., Ltd. (SHSE:688489) last week didn't sink the stock price. However, we believe that investors should be aware of some underlying factors which may be of concern.

How Do Unusual Items Influence Profit?

To properly understand Sansec Technology's profit results, we need to consider the CN¥7.0m expense attributed to unusual items. While deductions due to unusual items are disappointing in the first instance, there is a silver lining. We looked at thousands of listed companies and found that unusual items are very often one-off in nature. And that's hardly a surprise given these line items are considered unusual. Assuming those unusual expenses don't come up again, we'd therefore expect Sansec Technology to produce a higher profit next year, all else being equal.

An Unusual Tax Situation

Just as we noted the unusual items, we must inform you that Sansec Technology received a tax benefit which contributed CN¥10m to the bottom line. This is meaningful because companies usually pay tax rather than receive tax benefits. The receipt of a tax benefit is obviously a good thing, on its own. However, our data indicates that tax benefits can temporarily boost statutory profit in the year it is booked, but subsequently profit may fall back. In the likely event the tax benefit is not repeated, we'd expect to see its statutory profit levels drop, at least in the absence of strong growth. 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 Sansec Technology's Profit Performance

In the last year Sansec Technology 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. Having said that, it also had a unusual item reducing its profit. Given the contrasting considerations, we don't have a strong view as to whether Sansec Technology's profits are an apt reflection of its underlying potential for profit.
