Most readers would already be aware that MasTec's (NYSE:MTZ) stock increased significantly by 20% over the past three months. But the company's key financial indicators appear to be differing across the board and that makes us question whether or not the company's current share price momentum can be maintained. Specifically, we decided to study MasTec's ROE in this article.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors' money. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How Is ROE Calculated?

The formula for return on equity is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for MasTec is:

4.1% = US$116m ÷ US$2.8b (Based on the trailing twelve months to September 2024).

The 'return' is the profit over the last twelve months. So, this means that for every $1 of its shareholder's investments, the company generates a profit of $0.04.

What Has ROE Got To Do With Earnings Growth?

We have already established that ROE serves as an efficient profit-generating gauge for a company's future earnings. We now need to evaluate how much profit the company reinvests or "retains" for future growth which then gives us an idea about the growth potential of the company. Assuming everything else remains unchanged, the higher the ROE and profit retention, the higher the growth rate of a company compared to companies that don't necessarily bear these characteristics.

MasTec's Earnings Growth And 4.1% ROE

It is quite clear that MasTec's ROE is rather low. Even when compared to the industry average of 16%, the ROE figure is pretty disappointing. Therefore, it might not be wrong to say that the five year net income decline of 48% seen by MasTec was possibly a result of it having a lower ROE. We reckon that there could also be other factors at play here. For example, the business has allocated capital poorly, or that the company has a very high payout ratio.

So, as a next step, we compared MasTec's performance against the industry and were disappointed to discover that while the company has been shrinking its earnings, the industry has been growing its earnings at a rate of 16% over the last few years.

Earnings growth is an important metric to consider when valuing a stock. The investor should try to establish if the expected growth or decline in earnings, whichever the case may be, is priced in. This then helps them determine if the stock is placed for a bright or bleak future. What is MTZ worth today?

Is MasTec Making Efficient Use Of Its Profits?

Because MasTec doesn't pay any regular dividends, we infer that it is retaining all of its profits, which is rather perplexing when you consider the fact that there is no earnings growth to show for it. So there could be some other explanations in that regard. For instance, the company's business may be deteriorating.

Summary

In total, we're a bit ambivalent about MasTec's performance. While the company does have a high rate of profit retention, its low rate of return is probably hampering its earnings growth. That being so, the latest industry analyst forecasts show that the analysts are expecting to see a huge improvement in the company's earnings growth rate.
