The latest earnings report from Montauk Renewables, Inc. (NASDAQ:MNTK ) disappointed investors. We did some digging and think there are some comforting factors lying beneath the statutory profit numbers.

Examining Cashflow Against Montauk Renewables' Earnings

As finance nerds would already know, the accrual ratio from cashflow is a key measure for assessing how well a company's free cash flow (FCF) matches its profit. 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. The ratio shows us how much a company's profit exceeds its FCF.

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. Notably, there is some academic evidence that suggests that a high accrual ratio is a bad sign for near-term profits, generally speaking.

Over the twelve months to March 2026, Montauk Renewables recorded an accrual ratio of 0.31. 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. Over the last year it actually had negative free cash flow of US$99m, in contrast to the aforementioned profit of US$2.22m. Coming off the back of negative free cash flow last year, we imagine some shareholders might wonder if its cash burn of US$99m, this year, indicates high risk. Having said that it seems that a recent tax benefit and some unusual items have impacted its profit (and this its accrual ratio).

The Impact Of Unusual Items On Profit

Unfortunately (in the short term) Montauk Renewables saw its profit reduced by unusual items worth US$4.1m. If this was a non-cash charge, it would have made the accrual ratio better, if cashflow had stayed strong, so it's not great to see in combination with an uninspiring accrual ratio. While deductions due to unusual items are disappointing in the first instance, there is a silver lining. When we analysed the vast majority of listed companies worldwide, we found that significant unusual items are often not repeated. And, after all, that's exactly what the accounting terminology implies. Montauk Renewables took a rather significant hit from unusual items in the year to March 2026. All else being equal, this would likely have the effect of making the statutory profit look worse than its underlying earnings power.

An Unusual Tax Situation

In addition to the notable accrual ratio, we can see that Montauk Renewables received a tax benefit of US$4.2m. 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, our data indicates that tax benefits can temporarily boost statutory profit in the year it is booked, but subsequently profit may fall back. 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. 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 Montauk Renewables' Profit Performance

Summing up, Montauk Renewables' unusual items suggest that its statutory earnings were temporarily depressed, while its tax benefit is having the opposite effect, and its accrual ratio indicates a lack of free cash flow relative to profit. Based on these factors, we think that Montauk Renewables' statutory profits probably make it seem better than it is on an underlying level.
