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. But the reality is that when a company loses money each year, for long enough, its investors will usually take their share of those losses. Loss-making companies are always racing against time to reach financial sustainability, so investors in these companies may be taking on more risk than they should.

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 Innospec (NASDAQ:IOSP). Even if this company is fairly valued by the market, investors would agree that generating consistent profits will continue to provide Innospec with the means to add long-term value to shareholders.

How Quickly Is Innospec Increasing Earnings Per Share?

If you believe that markets are even vaguely efficient, then over the long term you'd expect a company's share price to follow its earnings per share (EPS) outcomes. Therefore, there are plenty of investors who like to buy shares in companies that are growing EPS. Over the last three years, Innospec has grown EPS by 16% per year. That's a good rate of growth, if it can be sustained.

Careful consideration of revenue growth and earnings before interest and taxation (EBIT) margins can help inform a view on the sustainability of the recent profit growth. Innospec's EBIT margins are flat but, worryingly, its revenue is actually down. While this may raise concerns, investors should investigate the reasoning behind this.

Are Innospec Insiders Aligned With All Shareholders?

It's pleasing to see company leaders with putting their money on the line, so to speak, because it increases alignment of incentives between the people running the business, and its true owners. So it is good to see that Innospec insiders have a significant amount of capital invested in the stock. Indeed, they hold US$30m worth of its stock. That shows significant buy-in, and may indicate conviction in the business strategy. While their ownership only accounts for 1.1%, this is still a considerable amount at stake to encourage the business to maintain a strategy that will deliver value to shareholders.

Does Innospec Deserve A Spot On Your Watchlist?

One important encouraging feature of Innospec is that it is growing profits. To add an extra spark to the fire, significant insider ownership in the company is another highlight. That combination is very appealing. So yes, we do think the stock is worth keeping an eye on. While we've looked at the quality of the earnings, we haven't yet done any work to value the stock. So if you like to buy cheap, you may want to check if Innospec is trading on a high P/E or a low P/E, relative to its industry.

Although Innospec certainly looks good, it may appeal to more investors if insiders were buying up shares. If you like to see companies with more skin in the game, then check out this handpicked selection of companies that not only boast of strong growth but have strong insider backing.
