Shenzhen Yinghe Technology Co., Ltd's (SZSE:300457) recent weak earnings report didn't cause a big stock movement. However, we believe that investors should be aware of some underlying factors which may be of concern.

The Power Of Non-Operating Revenue

Most companies divide classify their revenue as either 'operating revenue', which comes from normal operations, and other revenue, which could include government grants, for example. Oftentimes, non-operating revenue spikes are not repeated, so it makes sense to be cautious where non-operating revenue has made a very large contribution to total profit. However, we note that when non-operating revenue increases suddenly, it will sometimes generate an unsustainable boost to profit. It's worth noting that Shenzhen Yinghe Technology saw a big increase in non-operating revenue over the last year. In fact, our data indicates that non-operating revenue increased from CN¥827.7m to CN¥3.61b. The high levels of non-operating revenue are problematic because if (and when) they do not repeat, then overall revenue (and profitability) of the firm will fall. In order to better understand a company's profit result, it can sometimes help to consider whether the result would be very different without a sudden increase in non-operating revenue.

Our Take On Shenzhen Yinghe Technology's Profit Performance

Since Shenzhen Yinghe Technology saw a big increase in its non-operating revenue over the last twelve months, we'd be very cautious about relying too heavily on the statutory profit number, which would have benefitted from this potentially unsustainable change. As a result, we think it may well be the case that Shenzhen Yinghe Technology's underlying earnings power is lower than its statutory profit. But the good news is that its EPS growth over the last three years has been very impressive. 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. If you'd like to know more about Shenzhen Yinghe Technology as a business, it's important to be aware of any risks it's facing.
