It is hard to get excited after looking at American Superconductor's (NASDAQ:AMSC) recent performance, when its stock has declined 45% over the past three months. But if you pay close attention, you might find that its key financial indicators look quite decent, which could mean that the stock could potentially rise in the long-term given how markets usually reward more resilient long-term fundamentals. In this article, we decided to focus on American Superconductor's ROE.

Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.

How Is ROE Calculated?

The formula for ROE is:

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

So, based on the above formula, the ROE for American Superconductor is:

1.7% = US$3.2m ÷ US$193m (Based on the trailing twelve months to December 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 $0.02.

What Is The Relationship Between ROE And 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 all else is equal, companies that have both a higher return on equity and higher profit retention are usually the ones that have a higher growth rate when compared to companies that don't have the same features.

American Superconductor's Earnings Growth And 1.7% ROE

It is quite clear that American Superconductor's ROE is rather low. Not just that, even compared to the industry average of 8.6%, the company's ROE is entirely unremarkable. American Superconductor was still able to see a decent net income growth of 11% over the past five years. We reckon that there could be other factors at play here. For instance, the company has a low payout ratio or is being managed efficiently.

We then compared American Superconductor's net income growth with the industry and found that the company's growth figure is lower than the average industry growth rate of 17% in the same 5-year period, which is a bit concerning.

Earnings growth is an important metric to consider when valuing a stock. What investors need to determine next is if the expected earnings growth, or the lack of it, is already built into the share price. This then helps them determine if the stock is placed for a bright or bleak future.

Is American Superconductor Efficiently Re-investing Its Profits?

American Superconductor doesn't pay any regular dividends currently which essentially means that it has been reinvesting all of its profits into the business. This definitely contributes to the decent earnings growth number that we discussed above.

Summary

In total, it does look like American Superconductor has some positive aspects to its business. Specifically, its fairly high earnings growth number, which no doubt was backed by the company's high earnings retention. Still, the low ROE means that all that reinvestment is not reaping a lot of benefit to the investors. That being so, the latest analyst forecasts show that the company will continue to see an expansion in its earnings.
