For beginners, it can seem like a good idea (and an exciting prospect) to buy a company that tells a good story to investors, even if it currently lacks a track record of revenue and profit. Unfortunately, these high risk investments often have little probability of ever paying off, and many investors pay a price to learn their lesson. While a well funded company may sustain losses for years, it will need to generate a profit eventually, or else investors will move on and the company will wither away.

Despite being in the age of tech-stock blue-sky investing, many investors still adopt a more traditional strategy; buying shares in profitable companies like Onto Innovation (NYSE:ONTO). While this doesn't necessarily speak to whether it's undervalued, the profitability of the business is enough to warrant some appreciation - especially if its growing.

Onto Innovation's Earnings Per Share Are Growing

The market is a voting machine in the short term, but a weighing machine in the long term, so you'd expect share price to follow earnings per share (EPS) outcomes eventually. Therefore, there are plenty of investors who like to buy shares in companies that are growing EPS. Over the last three years, Onto Innovation has grown EPS by 16% per year. That growth rate is fairly good, assuming the company can keep it up.

One way to double-check a company's growth is to look at how its revenue, and earnings before interest and tax (EBIT) margins are changing. Onto Innovation maintained stable EBIT margins over the last year, all while growing revenue 11% to US$942m. That's progress.

Are Onto Innovation Insiders Aligned With All Shareholders?

We would not expect to see insiders owning a large percentage of a US$7.8b company like Onto Innovation. But we are reassured by the fact they have invested in the company. Given insiders own a significant chunk of shares, currently valued at US$57m, they have plenty of motivation to push the business to succeed. This should keep them focused on creating long term value for shareholders.

While it's always good to see some strong conviction in the company from insiders through heavy investment, it's also important for shareholders to ask if management compensation policies are reasonable. Our quick analysis into CEO remuneration would seem to indicate they are. For companies with market capitalisations between US$4.0b and US$12b, like Onto Innovation, the median CEO pay is around US$7.9m.

Onto Innovation's CEO took home a total compensation package worth US$5.6m in the year leading up to December 2023. That comes in below the average for similar sized companies and seems pretty reasonable. CEO remuneration levels are not the most important metric for investors, but when the pay is modest, that does support enhanced alignment between the CEO and the ordinary shareholders. Generally, arguments can be made that reasonable pay levels attest to good decision-making.

Is Onto Innovation Worth Keeping An Eye On?

One important encouraging feature of Onto Innovation is that it is growing profits. The growth of EPS may be the eye-catching headline for Onto Innovation, but there's more to bring joy for shareholders. With a meaningful level of insider ownership, and reasonable CEO pay, a reasonable mind might conclude that this is one stock worth watching. Of course, identifying quality businesses is only half the battle; investors need to know whether the stock is undervalued.
