Most readers would already be aware that Gentherm's (NASDAQ:THRM) stock increased significantly by 12% over the past month. 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. Particularly, we will be paying attention to Gentherm's ROE today.

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How Do You Calculate Return On Equity?

ROE can be calculated by using the formula:

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

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

6.3% = US$40m ÷ US$645m (Based on the trailing twelve months to December 2023).

The 'return' refers to a company's earnings over the last year. One way to conceptualize this is that for each $1 of shareholders' capital it has, the company made $0.06 in profit.

Why Is ROE Important For Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. Depending on how much of these profits the company reinvests or "retains", and how effectively it does so, we are then able to assess a company's earnings growth potential. 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.

A Side By Side comparison of Gentherm's Earnings Growth And 6.3% ROE

At first glance, Gentherm's ROE doesn't look very promising. A quick further study shows that the company's ROE doesn't compare favorably to the industry average of 12% either. For this reason, Gentherm's five year net income decline of 3.5% is not surprising given its lower ROE. We reckon that there could also be other factors at play here. 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 Gentherm'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 11% over the last few years.

Earnings growth is a huge factor in stock valuation. It's important for an investor to know whether the market has priced in the company's expected earnings growth (or decline). This then helps them determine if the stock is placed for a bright or bleak future. Is THRM fairly valued? This infographic on the company's intrinsic value has everything you need to know.

Is Gentherm Efficiently Re-investing Its Profits?

Gentherm doesn't pay any dividend, meaning that potentially all of its profits are being reinvested in the business, which doesn't explain why the company's earnings have shrunk if it is retaining all of its profits. So there might be other factors at play here which could potentially be hampering growth. For example, the business has faced some headwinds.

Summary

In total, we're a bit ambivalent about Gentherm'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. 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.
