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. Unfortunately, high risk investments often have little probability of ever paying off, and many investors pay a price to learn their lesson.

If, on the other hand, you like companies that have revenue, and even earn profits, then you may well be interested in IDT (NYSE:IDT). While that doesn't make the shares worth buying at any price, you can't deny that successful capitalism requires profit, eventually. Loss-making companies are always racing against time to reach financial sustainability, but time is often a friend of the profitable company, especially if it is growing.

How Fast Is IDT Growing Its Earnings Per Share?

In business, though not in life, profits are a key measure of success; and share prices tend to reflect earnings per share (EPS). So like the hint of a smile on a face that I love, growing EPS generally makes me look twice. You can imagine, then, that it almost knocked my socks off when I realized that IDT grew its EPS from US$0.057 to US$3.09, in one short year. Even though that growth rate is unlikely to be repeated, that looks like a breakout improvement.

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. IDT shareholders can take confidence from the fact that EBIT margins are up from 0.4% to 3.9%, and revenue is growing. That's great to see, on both counts.

While profitability drives the upside, prudent investors always check the balance sheet, too.

Are IDT Insiders Aligned With All Shareholders?

It makes me feel more secure owning shares in a company if insiders also own shares, thusly more closely aligning our interests. So it is good to see that IDT insiders have a significant amount of capital invested in the stock. Indeed, they have a glittering mountain of wealth invested in it, currently valued at US$429m. Coming in at 33% of the business, that holding gives insiders a lot of influence, and plenty of reason to generate value for shareholders. So it might be my imagination, but I do sense the glimmer of an opportunity.

It means a lot to see insiders invested in the business, but I find myself wondering if remuneration policies are shareholder friendly. A brief analysis of the CEO compensation suggests they are. I discovered that the median total compensation for the CEOs of companies like IDT with market caps between US$1.0b and US$3.2b is about US$3.7m.

The CEO of IDT only received US$940k in total compensation for the year ending . That looks like modest pay to me, and may hint at a certain respect for the interests of shareholders. 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. It can also be a sign of good governance, more generally.

Does IDT Deserve A Spot On Your Watchlist?

IDT's earnings per share growth have been levitating higher, like a mountain goat scaling the Alps. The sweetener is that insiders have a mountain of stock, and the CEO remuneration is quite reasonable. The sharp increase in earnings could signal good business momentum. Big growth can make big winners, so I do think IDT is worth considering carefully. Before you take the next step you should know about the 2 warning signs for IDT that we have uncovered.

Of course, you can do well (sometimes) buying stocks that are not growing earnings and do not have insiders buying shares. But as a growth investor I always like to check out companies that do have those features. You can access a free list of them here.
