Why Korea Aerospace Industries' (KRX:047810) Shaky Earnings Are Just The Beginning Of Its Problems

A lackluster earnings announcement from Korea Aerospace Industries, Ltd. (KRX:047810) last week didn't sink the stock price. We think that investors are worried about some weaknesses underlying the earnings.

Examining Cashflow Against Korea Aerospace Industries' 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). The accrual ratio subtracts the FCF from the profit for a given period, and divides the result by the average operating assets of the company over that time. 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 March 2025, Korea Aerospace Industries had an accrual ratio of 0.38. 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 ₩165.5b, a look at free cash flow indicates it actually burnt through ₩634b 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 ₩634b, this year, indicates high risk.

Our Take On Korea Aerospace Industries' Profit Performance

As we have made quite clear, we're a bit worried that Korea Aerospace Industries didn't back up the last year's profit with free cashflow. For this reason, we think that Korea Aerospace Industries' statutory profits may be a bad guide to its underlying earnings power, and might give investors an overly positive impression of the company. But on the bright side, its earnings per share have grown at an extremely impressive rate over the last three years. Of course, we've only just scratched the surface when it comes to analysing its earnings; one could also consider margins, forecast growth, and return on investment, among other factors. Keep in mind, when it comes to analysing a stock it's worth noting the risks involved.
