The market shrugged off Yangtze Optical Electronic Co., Ltd.'s (SHSE:688143) weak earnings report. While shares were up, we believe there are some factors in the earnings report that might cause investors some concerns.

Examining Cashflow Against Yangtze Optical Electronic's Earnings

One key financial ratio used to measure how well a company converts its profit to free cash flow (FCF) is the accrual ratio. In plain english, this ratio subtracts FCF from net profit, and divides that number by the company's average operating assets over that 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 it's not a problem to have a positive accrual ratio, indicating a certain level of non-cash profits, a high accrual ratio is arguably a bad thing, because it indicates paper profits are not matched by cash flow. 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 September 2024, Yangtze Optical Electronic had an accrual ratio of 0.31. Therefore, we know that it's free cashflow was significantly lower than its statutory profit, raising questions about how useful that profit figure really is. In the last twelve months it actually had negative free cash flow, with an outflow of CN¥165m despite its profit of CN¥9.03m, mentioned above. We also note that Yangtze Optical Electronic's free cash flow was actually negative last year as well, so we could understand if shareholders were bothered by its outflow of CN¥165m. However, we can see that a recent tax benefit, along with unusual items, have impacted its statutory profit, and therefore its accrual ratio.

The Impact Of Unusual Items On Profit

Given the accrual ratio, it's not overly surprising that Yangtze Optical Electronic's profit was boosted by unusual items worth CN¥12m 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 crunched the numbers on thousands of publicly listed companies, we found that a boost from unusual items in a given year is often not repeated the next year. Which is hardly surprising, given the name. Yangtze Optical Electronic had a rather significant contribution from unusual items relative to its profit to September 2024. As a result, we can surmise that the unusual items are making its statutory profit significantly stronger than it would otherwise be.

An Unusual Tax Situation

Moving on from the accrual ratio, we note that Yangtze Optical Electronic profited from a tax benefit which contributed CN¥4.0m to profit. This is of course a bit out of the ordinary, given it is more common for companies to be paying tax than receiving tax benefits! We're sure the company was pleased with its tax benefit. However, our data indicates that tax benefits can temporarily boost statutory profit in the year it is booked, but subsequently profit may fall back. Assuming the tax benefit is not repeated every year, we could see its profitability drop noticeably, all else being equal. While we think it's good that the company has booked a tax benefit, it does mean that there's every chance the statutory profit will come in a lot higher than it would be if the income was adjusted for one-off factors.

Our Take On Yangtze Optical Electronic's Profit Performance
