With its stock down 13% over the past three months, it is easy to disregard Power Integrations (NASDAQ:POWI). It seems that the market might have completely ignored the positive aspects of the company's fundamentals and decided to weigh-in more on the negative aspects. Long-term fundamentals are usually what drive market outcomes, so it's worth paying close attention. Specifically, we decided to study Power Integrations' ROE in this article.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors' money. Simply put, it is used to assess the profitability of a company in relation to its equity capital.

How Do You Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for Power Integrations is:

5.9% = US$43m ÷ US$731m (Based on the trailing twelve months to June 2024).

The 'return' refers to a company's earnings over the last year. So, this means that for every $1 of its shareholder's investments, the company generates a profit of $0.06.

Why Is ROE Important For Earnings Growth?

We have already established that ROE serves as an efficient profit-generating gauge for a company's future earnings. 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. 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.

A Side By Side comparison of Power Integrations' Earnings Growth And 5.9% ROE

When you first look at it, Power Integrations' ROE doesn't look that attractive. Next, when compared to the average industry ROE of 11%, the company's ROE leaves us feeling even less enthusiastic. For this reason, Power Integrations' five year net income decline of 10% is not surprising given its lower ROE. However, there could also be other factors causing the earnings to decline. For example, it is possible that the business has allocated capital poorly or that the company has a very high payout ratio.

However, when we compared Power Integrations' growth with the industry we found that while the company's earnings have been shrinking, the industry has seen an earnings growth of 21% in the same period. This is quite worrisome.

Earnings growth is an important metric to consider when valuing a stock. The investor should try to establish if the expected growth or decline in earnings, whichever the case may be, is priced in. Doing so will help them establish if the stock's future looks promising or ominous. Is Power Integrations fairly valued compared to other companies? These 3 valuation measures might help you decide.

Is Power Integrations Efficiently Re-investing Its Profits?

Power Integrations' low three-year median payout ratio of 24% (or a retention ratio of 76%) over the last three years should mean that the company is retaining most of its earnings to fuel its growth but the company's earnings have actually shrunk. This typically shouldn't be the case when a company is retaining most of its earnings. So there might be other factors at play here which could potentially be hampering growth. For instance, the business has faced some headwinds.

Additionally, Power Integrations has paid dividends over a period of at least ten years, which means that the company's management is determined to pay dividends even if it means little to no earnings growth. Our latest analyst data shows that the future payout ratio of the company is expected to rise to 39% over the next three years.

Summary

On the whole, we feel that the performance shown by Power Integrations can be open to many interpretations. Even though it appears to be retaining most of its profits, given the low ROE, investors may not be benefitting from all that reinvestment after all. The low earnings growth suggests our theory correct. With that said, we studied the latest analyst forecasts and found that while the company has shrunk its earnings in the past, analysts expect its earnings to grow in the future.
