Plexus' (NASDAQ:PLXS) stock is up by a considerable 40% over the past three months. However, we wonder if the company's inconsistent financials would have any adverse impact on the current share price momentum. Particularly, we will be paying attention to Plexus' ROE today.

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 simpler terms, it measures the profitability of a company in relation to shareholder's equity.

How Is ROE Calculated?

Return on equity 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:

8.4% = US$112m ÷ US$1.3b (Based on the trailing twelve months to September 2024).

The 'return' is the profit over the last twelve months. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.08 in profit.

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 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.

Plexus' Earnings Growth And 8.4% ROE

On the face of it, Plexus' ROE is not much to talk about. Yet, a closer study shows that the company's ROE is similar to the industry average of 10%. Having said that, Plexus' net income growth over the past five years is more or less flat. Remember, the company's ROE is not particularly great to begin with. Hence, this provides some context to the flat earnings growth seen by the company.

As a next step, we compared Plexus' net income growth with the industry and were disappointed to see that the company's growth is lower than the industry average growth of 14% in the same period.

Earnings growth is a huge factor in stock valuation. The investor should try to establish if the expected growth or decline in earnings, whichever the case may be, is priced in. This then helps them determine if the stock is placed for a bright or bleak future. What is PLXS worth today?

Is Plexus Using Its Retained Earnings Effectively?

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.

Summary

Overall, we have mixed feelings about Plexus. While the company does have a high rate of reinvestment, the low ROE means that all that reinvestment is not reaping any benefit to its investors, and moreover, its having a negative impact on the earnings growth. Having said that, looking at the current analyst estimates, we found that the company's earnings are expected to gain momentum. Are these analysts expectations based on the broad expectations for the industry, or on the company's fundamentals? Click here to be taken to our analyst's forecasts page for the company.
