Sumec Corporation Limited's (SHSE:600710) recent earnings report didn't offer any surprises, with the shares unchanged over the last week. We did some analysis to find out why and believe that investors might be missing some encouraging factors contained in the earnings.

Examining Cashflow Against Sumec's Earnings

In high finance, the key ratio used to measure how well a company converts reported profits into free cash flow (FCF) is the accrual ratio (from cashflow). To get the accrual ratio we first subtract FCF from profit for a period, and then divide that number by the average operating assets for the period. This ratio tells us how much of a company's profit is not backed by free cashflow.

Therefore, it's actually considered a good thing when a company has a negative accrual ratio, but a bad thing if its accrual ratio is positive. While having an accrual ratio above zero is of little concern, we do think it's worth noting when a company has a relatively high accrual ratio. Notably, there is some academic evidence that suggests that a high accrual ratio is a bad sign for near-term profits, generally speaking.

For the year to December 2023, Sumec had an accrual ratio of -0.33. Therefore, its statutory earnings were very significantly less than its free cashflow. To wit, it produced free cash flow of CN¥2.4b during the period, dwarfing its reported profit of CN¥1.03b. Sumec's free cash flow actually declined over the last year, which is disappointing, like non-biodegradable balloons. However, that's not all there is to consider. The accrual ratio is reflecting the impact of unusual items on statutory profit, at least in part.

How Do Unusual Items Influence Profit?

While the accrual ratio might bode well, we also note that Sumec's profit was boosted by unusual items worth CN¥400m in the last twelve months. While it's always nice to have higher profit, a large contribution from unusual items sometimes dampens our enthusiasm. When we analysed the vast majority of listed companies worldwide, we found that significant unusual items are often not repeated. Which is hardly surprising, given the name. 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 Sumec's Profit Performance

In conclusion, Sumec's accrual ratio suggests its statutory earnings are of good quality, but on the other hand the profits were boosted by unusual items. Based on these factors, we think that Sumec's profits are a reasonably conservative guide to its underlying profitability.
