It is hard to get excited after looking at SDI's (ASX:SDI) recent performance, when its stock has declined 16% over the past month. However, stock prices are usually driven by a company’s financial performance over the long term, which in this case looks quite promising.

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 SDI is:

11% = AU$10m ÷ AU$94m (Based on the trailing twelve months to June 2024).

The 'return' is the profit over the last twelve months. One way to conceptualize this is that for each A$1 of shareholders' capital it has, the company made A$0.11 in profit.

Why Is ROE Important For Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. 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. 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.

SDI's Earnings Growth And 11% ROE

At first glance, SDI seems to have a decent ROE. Especially when compared to the industry average of 7.3% the company's ROE looks pretty impressive. Probably as a result of this, SDI was able to see a decent growth of 6.7% over the last five years.

As a next step, we compared SDI's net income growth with the industry and found that the company has a similar growth figure when compared with the industry average growth rate of 8.3% in the same period.

The basis for attaching value to a company is, to a great extent, tied to its earnings growth. 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 SDI fairly valued compared to other companies? These 3 valuation measures might help you decide.

Is SDI Making Efficient Use Of Its Profits?

While SDI has a three-year median payout ratio of 53% (which means it retains 47% of profits), the company has still seen a fair bit of earnings growth in the past, meaning that its high payout ratio hasn't hampered its ability to grow.

Besides, SDI has been paying dividends for at least ten years or more. This shows that the company is committed to sharing profits with its shareholders. Our latest analyst data shows that the future payout ratio of the company is expected to drop to 35% over the next three years. Regardless, the ROE is not expected to change much for the company despite the lower expected payout ratio.
