To understand the value of a company's earnings growth, it is imperative to consider any dilution of shareholders' interests. As it happens, Alcoa issued 44% more new shares over the last year. That means its earnings are split among a greater number of shares. To talk about net income, without noticing earnings per share, is to be distracted by the big numbers while ignoring the smaller numbers that talk to per share value.

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

As it happens, we don't know how much the company made or lost three years ago, because we don't have the data. Zooming in to the last year, we still can't talk about growth rates coherently, since it made a loss last year. But mathematics aside, it is always good to see when a formerly unprofitable business come good (though we accept profit would have been higher if dilution had not been required). So you can see that the dilution has had a fairly significant impact on shareholders.

In the long term, if Alcoa's earnings per share can increase, then the share price should too. But on the other hand, we'd be far less excited to learn profit (but not EPS) was improving. For the ordinary retail shareholder, EPS is a great measure to check your hypothetical "share" of the company's profit.

The Impact Of Unusual Items On Profit

On top of the dilution, we should also consider the US$440m impact of unusual items in the last year, which had the effect of suppressing profit. 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 that's hardly a surprise given these line items are considered unusual. In the twelve months to December 2024, Alcoa had a big unusual items expense. All else being equal, this would likely have the effect of making the statutory profit look worse than its underlying earnings power.

Our Take On Alcoa's Profit Performance

To sum it all up, Alcoa took a hit from unusual items which pushed its profit down; without that, it would have made more money. But on the other hand, the company issued more shares, so without buying more shares each shareholder will end up with a smaller part of the profit. Based on these factors, it's hard to tell if Alcoa's profits are a reasonable reflection of its underlying profitability. If you'd like to know more about Alcoa as a business, it's important to be aware of any risks it's facing.
