Trump has pledged to "unleash" American oil and gas and these 15 US stocks have developments that are poised to benefit.

The Impact Of Unusual Items On Profit

For anyone who wants to understand DIO's profit beyond the statutory numbers, it's important to note that during the last twelve months statutory profit was reduced by ₩8.6b due to unusual items. While deductions due to unusual items are disappointing in the first instance, there is a silver lining. We looked at thousands of listed companies and found that unusual items are very often one-off in nature. And that's hardly a surprise given these line items are considered unusual. In the twelve months to September 2025, DIO had a big unusual items expense. As a result, we can surmise that the unusual items made its statutory profit significantly weaker than it would otherwise be.

An Unusual Tax Situation

Just as we noted the unusual items, we must inform you that DIO received a tax benefit which contributed ₩2.8b 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. And given that it lost money last year, it seems possible that the benefit is evidence that it now expects to find value in its past tax losses. However, the devil in the detail is that these kind of benefits only impact in the year they are booked, and are often one-off in nature. 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 DIO's Profit Performance

In its last report DIO received a tax benefit which might make its profit look better than it really is on a underlying level. Having said that, it also had a unusual item reducing its profit. After taking into account all these factors, we think that DIO's statutory results are a decent reflection of its underlying earnings power. So if you'd like to dive deeper into this stock, it's crucial to consider any risks it's facing.
