China Tianying Inc.'s (SZSE:000035 ) stock didn't jump after it announced some healthy earnings. We did some digging and believe investors may be worried about some underlying factors in the report.

Operating Revenue Or Not?

Companies will classify their revenue streams as either operating revenue or other revenue. Where possible, we prefer rely on operating revenue to get a better understanding of how the business is functioning. Importantly, the non-operating revenue often comes without associated ongoing costs, so it can boost profit by letting it fall straight to the bottom line, making the operating business seem better than it really is. Notably, China Tianying had a significant increase in non-operating revenue over the last year. In fact, our data indicates that non-operating revenue increased from CN¥490.0m to CN¥773.2m. If that non-operating revenue fails to manifest in the current year, then there's a real risk the bottom line profit result will be impacted negatively. Sometimes, you can get a better idea of the underlying earnings potential of a company by excluding unusual boosts to non-operating revenue.

Our Take On China Tianying's Profit Performance

Since China Tianying 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. For this reason, we think that China Tianying's statutory profits may be a bad guide to its underlying earnings power, and might give investors an overly positive impression of the company. But the happy news is that, while acknowledging we have to look beyond the statutory numbers, those numbers are still improving, with EPS growing at a very high rate over the last year. 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. So if you'd like to dive deeper into this stock, it's crucial to consider any risks it's facing.
