Why the Market Could Be Wrong About Monolithic Power Systems, Inc.

How to Calculate Return on Equity?

The formula for return on equity Is:

Return on Equity = Net Profit (from continuing operations) ÷ Stockholders’ Equity

So, based on the formula above, the ROE for a Monolithic Power System is:

26% = US$391m ÷ US$1.5b (Based on trailing twelve months to September 2022).

‘Returns’ are profits over the last twelve months. So, this means that for every $1 of its shareholders’ investment, the company makes a profit of $0.26.

What is the Relationship Between ROE and Earnings Growth?

So far, we have learned that ROE is a measure of a company’s profitability. Based on how much profit a company chooses to reinvest or “retain”, we can then evaluate the company’s future ability to generate profits. Assuming everything else remains unchanged, the higher the ROE and profit retention, the higher the growth rate of a company compared to companies that do not necessarily bear these characteristics.

Do Monolithic Power Systems Make Efficient Use Of Their Benefits?

Monolithic Power Systems has a significant three-year median payout ratio of 54%, meaning the company retains only 46% of its earnings. This means that the company has been able to achieve high earnings growth despite returning most of its profits to shareholders.

Additionally, Monolithic Power Systems has been paying dividends for eight years. This shows that the company is committed to sharing profits with its shareholders. Our latest analyst data shows that the company’s forward payout ratio is expected to fall to 22% over the next three years. Although the expected payout ratio is lower, the company’s ROE is not expected to change by much.


In general, we feel that Monolithic Power Systems’ performance has been quite good. We are particularly impressed by the considerable earnings growth posted by the company, which was likely made by its high ROE. While the company pays most of its earnings as dividends, it has been able to grow its earnings despite that, so that’s a good sign. Because of this, the company’s earnings growth is expected to slow down, as predicted in current analyst estimates.
