With its stock down 9.9% over the past month, it is easy to disregard Nova (NASDAQ:NVMI). However, stock prices are usually driven by a company’s financial performance over the long term, which in this case looks quite promising. Specifically, we decided to study Nova's ROE in this article.

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. Put another way, it reveals the company's success at turning shareholder investments into profits.

How Is ROE Calculated?

The formula for ROE is:

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

So, based on the above formula, the ROE for Nova is:

18% = US$154m ÷ US$843m (Based on the trailing twelve months to June 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 $0.18 in profit.

What Is The Relationship Between ROE And Earnings Growth?

Thus far, we have learned that ROE measures how efficiently a company is generating its profits. 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. 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 Nova's Earnings Growth And 18% ROE

At first glance, Nova seems to have a decent ROE. On comparing with the average industry ROE of 12% the company's ROE looks pretty remarkable. This probably laid the ground for Nova's significant 30% net income growth seen over the past five years. We reckon that there could also be other factors at play here. For instance, the company has a low payout ratio or is being managed efficiently.

Next, on comparing with the industry net income growth, we found that Nova's growth is quite high when compared to the industry average growth of 20% in the same period, which is great to see.

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. One good indicator of expected earnings growth is the P/E ratio which determines the price the market is willing to pay for a stock based on its earnings prospects. So, you may want to check if Nova is trading on a high P/E or a low P/E, relative to its industry.

Is Nova Using Its Retained Earnings Effectively?

Nova doesn't pay any regular dividends to its shareholders, meaning that the company has been reinvesting all of its profits into the business. This is likely what's driving the high earnings growth number discussed above.

Summary

On the whole, we feel that Nova's performance has been quite good. Particularly, we like that the company is reinvesting heavily into its business, and at a high rate of return. Unsurprisingly, this has led to an impressive earnings growth. With that said, the latest industry analyst forecasts reveal that the company's earnings growth is expected to slow down.
