MasTec, Inc.'s (NYSE:MTZ) Stock Is Rallying But Financials Look Ambiguous: Will The Momentum Continue?

Simply Wall St

MasTec's (NYSE:MTZ) stock is up by a considerable 12% over the past three months. However, we decided to pay attention to the company's fundamentals which don't appear to give a clear sign about the company's financial health. Particularly, we will be paying attention to MasTec's ROE today.

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 Do You Calculate Return On Equity?

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:

9.7% = US$293m ÷ US$3.0b (Based on the trailing twelve months to June 2025).

The 'return' refers to a company's earnings over the last year. So, this means that for every $1 of its shareholder's investments, the company generates a profit of $0.10.

What Is The Relationship Between ROE And Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. Based on how much of its profits the company chooses to reinvest or "retain", we are then able to evaluate a company's future ability to generate profits. Generally speaking, other things being equal, firms with a high return on equity and profit retention, have a higher growth rate than firms that don’t share these attributes.

MasTec's Earnings Growth And 9.7% ROE

On the face of it, MasTec's ROE is not much to talk about. We then compared the company's ROE to the broader industry and were disappointed to see that the ROE is lower than the industry average of 15%. Therefore, it might not be wrong to say that the five year net income decline of 33% seen by MasTec was probably the result of it having a lower ROE. We believe that there also might be other aspects that are negatively influencing the company's earnings prospects. For example, it is possible that 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 18% over the last few years.

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 might be other factors at play here which could potentially be hampering growth. For example, the business has faced some headwinds.

Conclusion

In total, we're a bit ambivalent about MasTec's performance. Even though it appears to be retaining most of its profits, given the low ROE, investors may not be benefitting from all that reinvestment after all. The low earnings growth suggests our theory correct. Having said that, looking at current analyst estimates, we found that the company's earnings growth rate is expected to see a huge improvement.
