The Power Of Non-Operating Revenue

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. It's worth noting that Hyosung saw a big increase in non-operating revenue over the last year. In fact, our data indicates that non-operating revenue increased from ₩13.2b to ₩251.4b. 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.

The Impact Of Unusual Items On Profit

Alongside that spike in non-operating revenue, it's also important to note that Hyosung'sprofit was boosted by unusual items worth ₩32b in the last twelve months. We can't deny that higher profits generally leave us optimistic, but we'd prefer it if the profit were to be sustainable. When we analysed the vast majority of listed companies worldwide, we found that significant unusual items are often not repeated. 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).

Our Take On Hyosung's Profit Performance

In the last year Hyosung's non-operating revenue really gave it a boost, but not in a way that is necessarily going to be sustained. And on top of that, it also saw an unusual item boost its profit, suggesting that next year might see a lower profit number, if these events are not repeated and everything else is equal. Considering all this we'd argue Hyosung's profits probably give an overly generous impression of its sustainable level of profitability. With this in mind, we wouldn't consider investing in a stock unless we had a thorough understanding of the risks.
