Zooming In On Nortech Systems' 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. The ratio shows us how much a company's profit exceeds its FCF.

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 September 2024, Nortech Systems had an accrual ratio of 0.23. We can therefore deduce that its free cash flow fell well short of covering its statutory profit. Over the last year it actually had negative free cash flow of US$4.6m, in contrast to the aforementioned profit of US$4.54m. We saw that FCF was US$4.8m a year ago though, so Nortech Systems has at least been able to generate positive FCF in the past. However, as we will discuss below, we can see that the company's accrual ratio has been impacted by its tax situation. This would certainly have contributed to the weak cash conversion. One positive for Nortech Systems shareholders is that it's accrual ratio was significantly better last year, providing reason to believe that it may return to stronger cash conversion in the future. Shareholders should look for improved cashflow relative to profit in the current year, if that is indeed the case.

An Unusual Tax Situation

In addition to the notable accrual ratio, we can see that Nortech Systems received a tax benefit of US$1.5m. This is meaningful because companies usually pay tax rather than receive tax benefits. We're sure the company was pleased with its tax benefit. However, the devil in the detail is that these kind of benefits only impact in the year they are booked, and are often one-off in nature. In the likely event the tax benefit is not repeated, we'd expect to see its statutory profit levels drop, at least in the absence of strong growth.

Our Take On Nortech Systems' Profit Performance

This year, Nortech Systems couldn't match its profit with cashflow. On top of that, the unsustainable nature of tax benefits mean that there's a chance profit may be lower next year, certainly in the absence of strong growth. Considering all this we'd argue Nortech Systems' profits probably give an overly generous impression of its sustainable level of profitability. In light of this, if you'd like to do more analysis on the company, it's vital to be informed of the risks involved.
