The Power Of Non-Operating Revenue

At most companies, some revenue streams, such as government grants, are accounted for as non-operating revenue, while the core business is said to produce operating revenue. 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. Notably, Wonlim had a significant increase in non-operating revenue over the last year. In fact, our data indicates that non-operating revenue increased from ₩6.20b to ₩10.3b. 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. Sometimes, you can get a better idea of the underlying earnings potential of a company by excluding unusual boosts to non-operating revenue.

How Do Unusual Items Influence Profit?

As well as that spike in non-operating revenue, we should also consider the ₩3.4b boost to profit coming from unusual items, over the last year. We can't deny that higher profits generally leave us optimistic, but we'd prefer it if the profit were to be sustainable. 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'. We can see that Wonlim's positive unusual items were quite significant relative to its profit in the year to December 2023. All else being equal, this would likely have the effect of making the statutory profit a poor guide to underlying earnings power.

Our Take On Wonlim's Profit Performance

In its last report Wonlim benefitted from a spike in non-operating revenue which may have boosted its profit in a way that may be no more sustainable than low quality coal mining. Furthermore, unusual items also made a nice positive contribution to its profit, which may well drop next year (all else being equal) if these phenomena are not repeated. Considering all this we'd argue Wonlim'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.
