Most readers would already be aware that Cognex's (NASDAQ:CGNX) stock increased significantly by 14% 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. In this article, we decided to focus on Cognex's ROE.

Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. Simply put, it is used to assess the profitability of a company in relation to its equity capital.

How To Calculate Return On Equity?

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 Cognex is:

6.7% = US$100m ÷ US$1.5b (Based on the trailing twelve months to March 2024).

The 'return' refers to a company's earnings over the last year. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.07 in profit.

Why Is ROE Important For Earnings Growth?

Thus far, we have learned that ROE measures how efficiently a company is generating its profits. Based on how much of its profits the company chooses to reinvest or "retain", we are then able to evaluate a company's future ability to generate profits. 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.

A Side By Side comparison of Cognex's Earnings Growth And 6.7% ROE

At first glance, Cognex's ROE doesn't look very promising. A quick further study shows that the company's ROE doesn't compare favorably to the industry average of 9.5% either. Therefore, it might not be wrong to say that the five year net income decline of 4.1% seen by Cognex was probably the result of it having a lower ROE. We believe that there also might be other aspects that are negatively influencing the company's earnings prospects. 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 Cognex's growth with the industry we found that while the company's earnings have been shrinking, the industry has seen an earnings growth of 15% in the same period. This is quite worrisome.

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.

Is Cognex Making Efficient Use Of Its Profits?

Cognex's low three-year median payout ratio of 21% (or a retention ratio of 79%) 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. The low payout should mean that the company is retaining most of its earnings and consequently, should see some growth. So there might be other factors at play here which could potentially be hampering growth. For instance, the business has faced some headwinds.

Moreover, Cognex has been paying dividends for nine years, which is a considerable amount of time, suggesting that management must have perceived that the shareholders prefer consistent dividends even though earnings have been shrinking. Looking at the current analyst consensus data, we can see that the company's future payout ratio is expected to rise to 26% over the next three years. Still, forecasts suggest that Cognex's future ROE will rise to 13% even though the the company's payout ratio is expected to rise. We presume that there could some other characteristics of the business that could be driving the anticipated growth in the company's ROE.

Summary

On the whole, we feel that the performance shown by Cognex can be open to many interpretations. While the company does have a high rate of profit retention, its low rate of return is probably hampering its earnings growth. Having said that, looking at current analyst estimates, we found that the company's earnings growth rate is expected to see a huge improvement.
