Benign Growth For International Consolidated Airlines Group S.A. (LON:IAG) Underpins Its Share Price

Simply Wall St

With a price-to-earnings (or "P/E") ratio of 6.7x International Consolidated Airlines Group S.A. (LON:IAG) may be sending very bullish signals at the moment, given that almost half of all companies in the United Kingdom have P/E ratios greater than 17x and even P/E's higher than 30x are not unusual. However, the P/E might be quite low for a reason and it requires further investigation to determine if it's justified.

With earnings growth that's superior to most other companies of late, International Consolidated Airlines Group has been doing relatively well. One possibility is that the P/E is low because investors think this strong earnings performance might be less impressive moving forward. If not, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

How Is International Consolidated Airlines Group's Growth Trending?

There's an inherent assumption that a company should far underperform the market for P/E ratios like International Consolidated Airlines Group's to be considered reasonable.

If we review the last year of earnings growth, the company posted a terrific increase of 21%. However, the latest three year period hasn't been as great in aggregate as it didn't manage to provide any growth at all. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

Turning to the outlook, the next three years should generate growth of 3.6% per annum as estimated by the analysts watching the company. With the market predicted to deliver 15% growth each year, the company is positioned for a weaker earnings result.

In light of this, it's understandable that International Consolidated Airlines Group's P/E sits below the majority of other companies. Apparently many shareholders weren't comfortable holding on while the company is potentially eyeing a less prosperous future.

The Final Word

Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

We've established that International Consolidated Airlines Group maintains its low P/E on the weakness of its forecast growth being lower than the wider market, as expected. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. It's hard to see the share price rising strongly in the near future under these circumstances.
