A Closer Look At Etherstack'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. The ratio shows us how much a company's profit exceeds its FCF.

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. That is not intended to imply we should worry about a positive accrual ratio, but it's worth noting where the accrual ratio is rather high. That's because some academic studies have suggested that high accruals ratios tend to lead to lower profit or less profit growth.

Over the twelve months to December 2021, Etherstack recorded an accrual ratio of 0.77. As a general rule, that bodes poorly for future profitability. To wit, the company did not generate one whit of free cashflow in that time. Even though it reported a profit of US$1.46m, a look at free cash flow indicates it actually burnt through US$166k in the last year. It's worth noting that Etherstack generated positive FCF of US$263k a year ago, so at least they've done it in the past. Importantly, we note an unusual tax situation, which we discuss below, has impacted the accruals ratio. This would partially explain why the accrual ratio was so poor. One positive for Etherstack 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 Etherstack received a tax benefit of US$391k. This is of course a bit out of the ordinary, given it is more common for companies to be paying tax than receiving tax benefits! We're sure the company was pleased with its tax benefit. And given that it lost money last year, it seems possible that the benefit is evidence that it now expects to find value in its past tax losses. However, our data indicates that tax benefits can temporarily boost statutory profit in the year it is booked, but subsequently profit may fall back. Assuming the tax benefit is not repeated every year, we could see its profitability drop noticeably, all else being equal. So while we think it's great to receive a tax benefit, it does tend to imply an increased risk that the statutory profit overstates the sustainable earnings power of the business.

Our Take On Etherstack's Profit Performance

This year, Etherstack 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. For the reasons mentioned above, we think that a perfunctory glance at Etherstack's statutory profits might make it look better than it really is on an underlying level.
