Little Excitement Around TransAlta Corporation's (TSE:TA) Earnings

With a price-to-earnings (or "P/E") ratio of 5.3x TransAlta Corporation (TSE:TA) may be sending very bullish signals at the moment, given that almost half of all companies in Canada have P/E ratios greater than 15x and even P/E's higher than 32x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so limited.

TransAlta certainly has been doing a good job lately as it's been growing earnings more than most other companies. It might be that many expect the strong earnings performance to degrade substantially, which has repressed the P/E. If not, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

What Are Growth Metrics Telling Us About The Low P/E?

TransAlta's P/E ratio would be typical for a company that's expected to deliver very poor growth or even falling earnings, and importantly, perform much worse than the market.

Taking a look back first, we see that the company grew earnings per share by an impressive 383% last year. However, the latest three year period hasn't been as great in aggregate as it didn't manage to provide any growth at all. Therefore, it's fair to say that earnings growth has been inconsistent recently for the company.

Looking ahead now, EPS is anticipated to slump, contracting by 31% each year during the coming three years according to the four analysts following the company. That's not great when the rest of the market is expected to grow by 7.8% per annum.

In light of this, it's understandable that TransAlta's P/E would sit below the majority of other companies. Nonetheless, there's no guarantee the P/E has reached a floor yet with earnings going in reverse. Even just maintaining these prices could be difficult to achieve as the weak outlook is weighing down the shares.

The Key Takeaway

While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

As we suspected, our examination of TransAlta's analyst forecasts revealed that its outlook for shrinking earnings is contributing to its low P/E. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. Unless these conditions improve, they will continue to form a barrier for the share price around these levels.

Plus, you should also learn about these 4 warning signs we've spotted with TransAlta (including 1 which is potentially serious).

It's important to make sure you look for a great company, not just the first idea you come across. So take a peek at this free list of interesting companies with strong recent earnings growth (and a low P/E).
