Truking Technology Limited's (SZSE:300358) recent weak earnings report didn't cause a big stock movement. Our analysis suggests that along with soft profit numbers, investors should be aware of some other underlying weaknesses in the numbers.

How Do Unusual Items Influence Profit?

To properly understand Truking Technology's profit results, we need to consider the CN¥11m gain attributed to unusual items. While we like to see profit increases, we tend to be a little more cautious when unusual items have made a big contribution. We ran the numbers on most publicly listed companies worldwide, and it's very common for unusual items to be once-off in nature. And that's as you'd expect, given these boosts are described as 'unusual'. Assuming those unusual items don't show up again in the current year, we'd thus expect profit to be weaker next year (in the absence of business growth, that is).

An Unusual Tax Situation

Just as we noted the unusual items, we must inform you that Truking Technology received a tax benefit which contributed CN¥39m 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. 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. So while we think it's great to receive a tax benefit, it does tend to imply an increased risk that the statutory profit overstates the sustainable earnings power of the business.

Our Take On Truking Technology's Profit Performance

In the last year Truking 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. Furthermore, it also benefitted from a positive unusual item, which boosted the profit result even higher. Considering all this we'd argue Truking Technology's profits probably give an overly generous impression of its sustainable level of profitability.
