StarPower Semiconductor Ltd. (SHSE:603290) just released a solid earnings report, and the stock displayed some strength. However, we think that shareholders should be cautious as we found some worrying factors underlying the profit.

Zooming In On StarPower Semiconductor'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. 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'.

That means a negative accrual ratio is a good thing, because it shows that the company is bringing in more free cash flow than its profit would suggest. 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".

StarPower Semiconductor has an accrual ratio of 0.65 for the year to December 2023. 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. Over the last year it actually had negative free cash flow of CN¥1.8b, in contrast to the aforementioned profit of CN¥910.5m. Coming off the back of negative free cash flow last year, we imagine some shareholders might wonder if its cash burn of CN¥1.8b, this year, indicates high risk.

Our Take On StarPower Semiconductor's Profit Performance

As we have made quite clear, we're a bit worried that StarPower Semiconductor didn't back up the last year's profit with free cashflow. As a result, we think it may well be the case that StarPower Semiconductor's underlying earnings power is lower than its statutory profit. But on the bright side, its earnings per share have grown at an extremely impressive rate over the last three years. The goal of this article has been to assess how well we can rely on the statutory earnings to reflect the company's potential, but there is plenty more to consider.
