Plexus (NASDAQ:PLXS) has had a great run on the share market with its stock up by a significant 28% over the last three months. However, we decided to pay attention to the company's fundamentals which don't appear to give a clear sign about the company's financial health. In this article, we decided to focus on Plexus' ROE.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors' money. Put another way, it reveals the company's success at turning shareholder investments into profits.

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 Plexus is:

8.1% = US$102m ÷ US$1.3b (Based on the trailing twelve months to March 2024).

The 'return' is the amount earned after tax over the last twelve months. One way to conceptualize this is that for each $1 of shareholders' capital it has, the company made $0.08 in profit.

What Has ROE Got To Do With Earnings Growth?

Thus far, we have learned that ROE measures how efficiently a company is generating its profits. 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. Generally speaking, other things being equal, firms with a high return on equity and profit retention, have a higher growth rate than firms that don't share these attributes.

Plexus' Earnings Growth And 8.1% ROE

At first glance, Plexus' ROE doesn't look very promising. However, given that the company's ROE is similar to the average industry ROE of 9.6%, we may spare it some thought. Having said that, Plexus' net income growth over the past five years is more or less flat. Bear in mind, the company's ROE is not very high. So that could also be one of the reasons behind the company's flat growth in earnings.

We then compared Plexus' net income growth with the industry and found that the company's growth figure is lower than the average industry growth rate of 15% in the same 5-year period, which is a bit concerning.

Earnings growth is an important metric to consider when valuing a stock. 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 Plexus Making Efficient Use Of Its Profits?

Plexus doesn't pay any regular dividends, meaning that the company is keeping all of its profits, which makes us wonder why it is retaining its earnings if it can't use them to grow its business. So there could be some other explanations in that regard. For instance, the company's business may be deteriorating.

Conclusion

In total, we're a bit ambivalent about Plexus' performance. 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, the latest industry analyst forecasts reveal that the company's earnings are expected to accelerate.
