A Closer Look At Nostrum Oil & Gas' 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.

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 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 2023, Nostrum Oil & Gas had an accrual ratio of 2.93. That means it didn't generate anywhere near enough free cash flow to match its profit. As a general rule, that bodes poorly for future profitability. To wit, it produced free cash flow of US$7.0m during the period, falling well short of its reported profit of US$777.3m. Nostrum Oil & Gas shareholders will no doubt be hoping that its free cash flow bounces back next year, since it was down over the last twelve months. Having said that, there is more to consider. We must also consider the impact of unusual items on statutory profit (and thus the accrual ratio), as well as note the ramifications of the company issuing new shares. One positive for Nostrum Oil & Gas 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.

To understand the value of a company's earnings growth, it is imperative to consider any dilution of shareholders' interests. As it happens, Nostrum Oil & Gas issued 814% more new shares over the last year. As a result, its net income is now split between a greater number of shares. Per share metrics like EPS help us understand how much actual shareholders are benefitting from the company's profits, while the net income level gives us a better view of the company's absolute size.

A Look At The Impact Of Nostrum Oil & Gas' Dilution On Its Earnings Per Share (EPS)

Nostrum Oil & Gas was losing money three years ago. Zooming in to the last year, we still can't talk about growth rates coherently, since it made a loss last year. What we do know is that while it's great to see a profit over the last twelve months, that profit would have been better, on a per share basis, if the company hadn't needed to issue shares. So you can see that the dilution has had a fairly significant impact on shareholders.

If Nostrum Oil & Gas' EPS can grow over time then that drastically improves the chances of the share price moving in the same direction. But on the other hand, we'd be far less excited to learn profit (but not EPS) was improving. For that reason, you could say that EPS is more important that net income in the long run, assuming the goal is to assess whether a company's share price might grow.

How Do Unusual Items Influence Profit?

The fact that the company had unusual items boosting profit by US$770m, in the last year, probably goes some way to explain why its accrual ratio was so weak. While we like to see profit increases, we tend to be a little more cautious when unusual items have made a big contribution. When we crunched the numbers on thousands of publicly listed companies, we found that a boost from unusual items in a given year is often not repeated the next year. And, after all, that's exactly what the accounting terminology implies. We can see that Nostrum Oil & Gas' positive unusual items were quite significant relative to its profit in the year to September 2023. All else being equal, this would likely have the effect of making the statutory profit a poor guide to underlying earnings power.

Our Take On Nostrum Oil & Gas' Profit Performance

Nostrum Oil & Gas didn't back up its earnings with free cashflow, but this isn't too surprising given profits were inflated by unusual items. The dilution means the results are weaker when viewed from a per-share perspective. On reflection, the above-mentioned factors give us the strong impression that Nostrum Oil & Gas'underlying earnings power is not as good as it might seem, based on the statutory profit numbers. 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.
