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 completely 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.

So if you're like me, you might be more interested in profitable, growing companies, like China Gas Holdings (HKG:384). Now, I'm not saying that the stock is necessarily undervalued today; but I can't shake an appreciation for the profitability of the business itself. Conversely, a loss-making company is yet to prove itself with profit, and eventually the sweet milk of external capital may run sour.

How Quickly Is China Gas Holdings 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). It's no surprise, then, that I like to invest in companies with EPS growth. Impressively, China Gas Holdings has grown EPS by 32% per year, compound, in the last three years. If the company can sustain that sort of growth, we'd expect shareholders to come away winners.

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. On the one hand, China Gas Holdings's EBIT margins fell over the last year, but on the other hand, revenue grew. So if EBIT margins can stabilize, this top-line growth should pay off for shareholders.

In the chart below, you can see how the company has grown earnings, and revenue, over time. To see the actual numbers, click on the chart.

While we live in the present moment at all times, there's no doubt in my mind that the future matters more than the past. So why not check this interactive chart depicting future EPS estimates, for China Gas Holdings?

Are China Gas Holdings Insiders Aligned With All Shareholders?

We would not expect to see insiders owning a large percentage of a HK$127b company like China Gas Holdings. But we do take comfort from the fact that they are investors in the company. Indeed, they have a glittering mountain of wealth invested in it, currently valued at HK$13b. I would find that kind of skin in the game quite encouraging, if I owned shares, since it would ensure that the leaders of the company would also experience my success, or failure, with the stock.
