Investors were disappointed with MLOptic Corp.'s (SHSE:688502) recent earnings. We think there is more to the story than simply soft profit numbers. Our analysis shows that there are some other factors of concern.

Zooming In On MLOptic's Earnings

As finance nerds would already know, the accrual ratio from cashflow is a key measure for assessing how well a company's free cash flow (FCF) matches its profit. 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. You could think of the accrual ratio from cashflow as the 'non-FCF profit ratio'.

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. To quote a 2014 paper by Lewellen and Resutek, "firms with higher accruals tend to be less profitable in the future".

For the year to September 2024, MLOptic had an accrual ratio of 0.42. As a general rule, that bodes poorly for future profitability. And indeed, during the period the company didn't produce any free cash flow whatsoever. Even though it reported a profit of CN¥34.9m, a look at free cash flow indicates it actually burnt through CN¥292m in the last year. Coming off the back of negative free cash flow last year, we imagine some shareholders might wonder if its cash burn of CN¥292m, this year, indicates high risk. 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.

The Impact Of Unusual Items On Profit

The fact that the company had unusual items boosting profit by CN¥6.4m, in the last year, probably goes some way to explain why its accrual ratio was so weak. 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. Which is hardly surprising, given the name. If MLOptic doesn't see that contribution repeat, then all else being equal we'd expect its profit to drop over the current year.

Our Take On MLOptic's Profit Performance

MLOptic had a weak accrual ratio, but its profit did receive a boost from unusual items. Considering all this we'd argue MLOptic'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. Case in point: We've spotted 2 warning signs for MLOptic you should be aware of.
