Particularly, we will be paying attention to SMA Solar Technology's ROE today.

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 SMA Solar Technology is:

12% = €56m ÷ €464m (Based on the trailing twelve months to December 2022).

The 'return' is the income the business earned over the last year. One way to conceptualize this is that for each €1 of shareholders' capital it has, the company made €0.12 in profit.

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. 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.

A Side By Side comparison of SMA Solar Technology's Earnings Growth And 12% ROE

To start with, SMA Solar Technology's ROE looks acceptable. Yet, the fact that the company's ROE is lower than the industry average of 16% does temper our expectations. That being the case, the significant five-year 23% net income growth reported by SMA Solar Technology comes as a pleasant surprise. We believe that there might be other aspects that are positively influencing the company's earnings growth. For instance, the company has a low payout ratio or is being managed efficiently. Bear in mind, the company does have a respectable ROE. It is just that the industry ROE is higher. So this certainly also provides some context to the high earnings growth seen by the company.

Next, on comparing SMA Solar Technology's net income growth with the industry, we found that the company's reported growth is similar to the industry average growth rate of 20% in the same period.

The basis for attaching value to a company is, to a great extent, tied to its earnings growth. 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. Has the market priced in the future outlook for S92?

Is SMA Solar Technology Making Efficient Use Of Its Profits?

While the company did pay out a portion of its dividend in the past, it currently doesn't pay a dividend. This is likely what's driving the high earnings growth number discussed above.
