To understand the value of a company's earnings growth, it is imperative to consider any dilution of shareholders' interests. In fact, Tourmaline Oil increased the number of shares on issue by 6.5% over the last twelve months by issuing new shares. That means its earnings are split among a greater number of shares. To celebrate net income while ignoring dilution is like rejoicing because you have a single slice of a larger pizza, but ignoring the fact that the pizza is now cut into many more slices.

A Look At The Impact Of Tourmaline Oil's Dilution On Its Earnings Per Share (EPS)

Tourmaline Oil's net profit dropped by 50% per year over the last three years. And even focusing only on the last twelve months, we see profit is down 29%. Sadly, earnings per share fell further, down a full 32% in that time. So you can see that the dilution has had a bit of an impact on shareholders.

In the long term, if Tourmaline Oil's earnings per share can increase, then the share price should too. However, if its profit increases while its earnings per share stay flat (or even fall) then shareholders might not see much benefit. For the ordinary retail shareholder, EPS is a great measure to check your hypothetical "share" of the company's profit.

How Do Unusual Items Influence Profit?

Alongside that dilution, it's also important to note that Tourmaline Oil's profit was boosted by unusual items worth CA$264m in the last twelve months. While we like to see profit increases, we tend to be a little more cautious when unusual items have made a big contribution. We ran the numbers on most publicly listed companies worldwide, and it's very common for unusual items to be once-off in nature. And, after all, that's exactly what the accounting terminology implies. Assuming those unusual items don't show up again in the current year, we'd thus expect profit to be weaker next year (in the absence of business growth, that is).

Our Take On Tourmaline Oil's Profit Performance

In its last report Tourmaline Oil benefitted from unusual items which boosted its profit, which could make the profit seem better than it really is on a sustainable basis. On top of that, the dilution means that its earnings per share performance is worse than its profit performance. For the reasons mentioned above, we think that a perfunctory glance at Tourmaline Oil's statutory profits might make it look better than it really is on an underlying level. So if you'd like to dive deeper into this stock, it's crucial to consider any risks it's facing.
