Knife River's (NYSE:KNF) stock is up by a considerable 41% over the past three months. Given the company's impressive performance, we decided to study its financial indicators more closely as a company's financial health over the long-term usually dictates market outcomes. Specifically, we decided to study Knife River's ROE in this article.

ROE or return on equity is a useful tool to assess how effectively a company can generate returns on the investment it received from its shareholders. 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?

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 Knife River is:

14% = US$199m ÷ US$1.4b (Based on the trailing twelve months to September 2024).

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 $0.14 in profit.

What Has ROE Got To Do With 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. 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.

Knife River's Earnings Growth And 14% ROE

To start with, Knife River's ROE looks acceptable. Further, the company's ROE is similar to the industry average of 15%. This certainly adds some context to Knife River's moderate 12% net income growth seen over the past five years.

We then compared Knife River's net income growth with the industry and found that the company's growth figure is lower than the average industry growth rate of 21% in the same 5-year period, which is a bit concerning.

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. One good indicator of expected earnings growth is the P/E ratio which determines the price the market is willing to pay for a stock based on its earnings prospects. So, you may want to check if Knife River is trading on a high P/E or a low P/E, relative to its industry.

Is Knife River Using Its Retained Earnings Effectively?

Knife River doesn't pay any regular dividends, meaning that all of its profits are being reinvested in the business, which explains the fair bit of earnings growth the company has seen.

Summary

On the whole, we feel that Knife River's performance has been quite good. Specifically, we like that the company is reinvesting a huge chunk of its profits at a high rate of return. This of course has caused the company to see a good amount of growth in its earnings.
