Investors were disappointed with Rigol Technologies Co., Ltd.'s (SHSE:688337) recent earnings release. We did some digging and found some underlying numbers that are worrying.

Zooming In On Rigol Technologies' 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. You could think of the accrual ratio from cashflow as the 'non-FCF profit ratio'.

As a result, a negative accrual ratio is a positive for the company, and a positive accrual ratio is a negative. 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. 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 December 2023, Rigol Technologies had an accrual ratio of 0.36. 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¥177m despite its profit of CN¥108.0m, mentioned above. Coming off the back of negative free cash flow last year, we imagine some shareholders might wonder if its cash burn of CN¥177m, 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¥45m, in the last year, probably goes some way to explain why its accrual ratio was so weak. While it's always nice to have higher profit, a large contribution from unusual items sometimes dampens our enthusiasm. 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. And, after all, that's exactly what the accounting terminology implies. Rigol Technologies had a rather significant contribution from unusual items relative to its profit 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 Rigol Technologies' Profit Performance

Rigol Technologies had a weak accrual ratio, but its profit did receive a boost from unusual items. For the reasons mentioned above, we think that a perfunctory glance at Rigol Technologies' statutory profits might make it look better than it really is on an underlying level.
