Why EnSilica's (LON:ENSI) Earnings Are Weaker Than They Seem

Examining Cashflow Against EnSilica's 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). 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 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".

EnSilica has an accrual ratio of 0.32 for the year to May 2023. Unfortunately, that means its free cash flow was a lot less than its statutory profit, which makes us doubt the utility of profit as a guide. In the last twelve months it actually had negative free cash flow, with an outflow of UK£2.7m despite its profit of UK£1.79m, mentioned above. Coming off the back of negative free cash flow last year, we imagine some shareholders might wonder if its cash burn of UK£2.7m, this year, indicates high risk. 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.

An Unusual Tax Situation

In addition to the notable accrual ratio, we can see that EnSilica received a tax benefit of UK£1.7m. It's always a bit noteworthy when a company is paid by the tax man, rather than paying the tax man. 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 EnSilica's Profit Performance

EnSilica's accrual ratio indicates weak cashflow relative to earnings, which perhaps arises in part from the tax benefit it received this year. If the tax benefit is not repeated, then profit would drop next year, all else being equal. For the reasons mentioned above, we think that a perfunctory glance at EnSilica's statutory profits might make it look better than it really is on an underlying level. So while earnings quality is important, it's equally important to consider the risks facing EnSilica at this point in time.
