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. 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 Portland General Electric (NYSE:POR). While profit isn't the sole metric that should be considered when investing, it's worth recognising businesses that can consistently produce it.

How Fast Is Portland General Electric Growing?

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. That means EPS growth is considered a real positive by most successful long-term investors. We can see that in the last three years Portland General Electric grew its EPS by 8.2% per year. That's a pretty good rate, if the company can sustain it.

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. The good news is that Portland General Electric is growing revenues, and EBIT margins improved by 3.1 percentage points to 16%, over the last year. That's great to see, on both counts.
