How Do You Calculate Return On Equity?

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 Onto Innovation is:

14% = US$223m ÷ US$1.6b (Based on the trailing twelve months to December 2022).

The 'return' is the yearly profit. So, this means that for every $1 of its shareholder's investments, the company generates a profit of $0.14.

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.

Onto Innovation's Earnings Growth And 14% ROE

To start with, Onto Innovation's ROE looks acceptable. Be that as it may, the company's ROE is still quite lower than the industry average of 18%. However, we are pleased to see the impressive 48% net income growth reported by Onto Innovation over the past five years. Therefore, there could be other causes behind this growth. For example, it is possible that the company's management has made some good strategic decisions, or that the company has a low payout ratio. Bear in mind, the company does have a respectable ROE. It is just that the industry ROE is higher. So this certainly also provides some context to the high earnings growth seen by the company.

We then compared Onto Innovation's net income growth with the industry and we're pleased to see that the company's growth figure is higher when compared with the industry which has a growth rate of 28% in the same period.

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. Is Onto Innovation fairly valued compared to other companies? These 3 valuation measures might help you decide.
