It is hard to get excited after looking at Pentair's (NYSE:PNR) recent performance, when its stock has declined 15% over the past three months. However, stock prices are usually driven by a company’s financial performance over the long term, which in this case looks quite promising. In this article, we decided to focus on Pentair's ROE.

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 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 Pentair is:

18% = US$626m ÷ US$3.6b (Based on the trailing twelve months to December 2024).

The 'return' is the income the business earned over the last year. So, this means that for every $1 of its shareholder's investments, the company generates a profit of $0.18.

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. Assuming everything else remains unchanged, the higher the ROE and profit retention, the higher the growth rate of a company compared to companies that don't necessarily bear these characteristics.

Pentair's Earnings Growth And 18% ROE

To start with, Pentair's ROE looks acceptable. On comparing with the average industry ROE of 14% the company's ROE looks pretty remarkable. Probably as a result of this, Pentair was able to see a decent growth of 12% over the last five years.

As a next step, we compared Pentair'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 15% in the same period.

Earnings growth is an important metric to consider when valuing a stock. What investors need to determine next is if the expected earnings growth, or the lack of it, is already built into the share price. Doing so will help them establish if the stock's future looks promising or ominous. Is PNR fairly valued? This infographic on the company's intrinsic value has everything you need to know.

Is Pentair Using Its Retained Earnings Effectively?

Pentair's three-year median payout ratio to shareholders is 24% (implying that it retains 76% of its income), which is on the lower side, so it seems like the management is reinvesting profits heavily to grow its business.

Besides, Pentair 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 19% over the next three years. However, the company's ROE is not expected to change by much despite the lower expected payout ratio.
