With EPS Growth And More, Nanosonics (ASX:NAN) Makes An Interesting Case

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 can act like a sponge for capital - so investors should be cautious that they're not throwing good money after bad.

So if this idea of high risk and high reward doesn't suit, you might be more interested in profitable, growing companies, like Nanosonics (ASX:NAN). Now this is not to say that the company presents the best investment opportunity around, but profitability is a key component to success in business.

How Fast Is Nanosonics Growing Its Earnings Per Share?

Nanosonics has undergone a massive growth in earnings per share over the last three years. So much so that this three year growth rate wouldn't be a fair assessment of the company's future. So it would be better to isolate the growth rate over the last year for our analysis. Nanosonics' EPS shot up from AU$0.043 to AU$0.068; a result that's bound to keep shareholders happy. That's a commendable gain of 59%.

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. Nanosonics shareholders can take confidence from the fact that EBIT margins are up from 5.0% to 9.0%, and revenue is growing. Both of which are great metrics to check off for potential growth.

Enough to lead management's decision making process down a path that brings the most benefit to shareholders.
