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 NPK International is:

10% = US$33m ÷ US$316m (Based on the trailing twelve months to September 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 $0.10.

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. 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.

NPK International's Earnings Growth And 10% ROE

At first glance, NPK International's ROE doesn't look very promising. Next, when compared to the average industry ROE of 14%, the company's ROE leaves us feeling even less enthusiastic. Despite this, surprisingly, NPK International saw an exceptional 42% net income growth over the past five years. Therefore, there could be other reasons behind this growth. Such as - high earnings retention or an efficient management in place.

As a next step, we compared NPK International's net income growth with the industry and were disappointed to see that the company's growth is lower than the industry average growth of 53% in the same period.

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 NPK International Using Its Retained Earnings Effectively?

NPK International doesn't pay any regular dividends to its shareholders, meaning that the company has been reinvesting all of its profits into the business. This is likely what's driving the high earnings growth number discussed above.

Summary

In total, it does look like NPK International has some positive aspects to its business. That is, a decent growth in earnings backed by a high rate of reinvestment. However, we do feel that that earnings growth could have been higher if the business were to improve on the low ROE rate. Especially given how the company is reinvesting a huge chunk of its profits. Having said that, the company's earnings growth is expected to slow down, as forecasted in the current analyst estimates.
