Examining Cashflow Against PSK's Earnings

Many investors haven't heard of the accrual ratio from cashflow, but it is actually a useful measure of how well a company's profit is backed up by free cash flow (FCF) during a given period. 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'.

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 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. That's because some academic studies have suggested that high accruals ratios tend to lead to lower profit or less profit growth.

For the year to September 2025, PSK had an accrual ratio of 0.21. Therefore, we know that it's free cashflow was significantly lower than its statutory profit, which is hardly a good thing. To wit, it produced free cash flow of ₩14b during the period, falling well short of its reported profit of ₩74.6b. PSK shareholders will no doubt be hoping that its free cash flow bounces back next year, since it was down over the last twelve months.

Our Take On PSK's Profit Performance

PSK didn't convert much of its profit to free cash flow in the last year, which some investors may consider rather suboptimal. Because of this, we think that it may be that PSK's statutory profits are better than its underlying earnings power. In further bad news, its earnings per share decreased in the last year. At the end of the day, it's essential to consider more than just the factors above, if you want to understand the company properly. With this in mind, we wouldn't consider investing in a stock unless we had a thorough understanding of the risks. For example, PSK has 3 warning signs (and 1 which is concerning) we think you should know about.

This note has only looked at a single factor that sheds light on the nature of PSK's profit. But there is always more to discover if you are capable of focussing your mind on minutiae. For example, many people consider a high return on equity as an indication of favorable business economics, while others like to 'follow the money' and search out stocks that insiders are buying. While it might take a little research on your behalf, you may find this free collection of companies boasting high return on equity, or this list of stocks with significant insider holdings to be useful.
