What is a Good P/E Ratio For Delta Air Lines, Inc. (NYSE: DAL)?


Delta Air Lines, Inc. (NYSE: DAL), an industrials business with a market capitalization of $38.2 billion, currently trades at a P/E multiple of 10.7x which is below the sector’s median multiple of 22.2x. Although this makes DAL look attractive, investors may change their mind after reviewing the assumptions behind the P/E ratio. In the post below, I explain how to apply P/E multiples and what to watch out for.

How To Utilize Delta’s PE Multiples

A multiples valuation, also known as a comparable companies analysis, determines the value of a subject company by benchmarking the subject’s financial performance against companies deemed to be similar. We can then determine if a company is undervalued or overvalued relative to its peers by comparing metrics like growth, profit margin, and valuation multiples.

P/E Ratio is a valuation metric that indicates the multiple of earnings investors are willing to pay for one share of a company:

P/E Ratio = Stock Price ÷ Earnings Per Share

The P/E ratio by itself is not very helpful at all. It is only useful when comparing it to other companies that are considered similar to the subject company. The basic idea is that companies with similar characteristics should trade at similar multiples, all other things being equal. Therefore, we can come to a conclusion about the stock if the ratios are different. In the chart below, I compare Delta’s P/E ratio to its peer group that includes United Continental Holdings, Inc. (NYSE: UAL), Southwest Airlines Company (NYSE: LUV), Alaska Air Group, Inc.(NYSE: ALK) and Spirit Airlines, Inc. (NASDAQ: SAVE).

Since Delta’s P/E ratio of 10.7x is higher than the median of its peers (8.4x), it means that investors are paying more than they should for each dollar of DAL’s earnings. As such, our analysis shows that DAL represents an overvalued stock. Furthermore, finbox.io’s P/E Ratio Model calculates a fair value of approximately $43.50 per share which implies roughly 18.0% downside.

I selected a fair multiple of 8.5x in my analysis by averaging Delta’s current P/E ratio with its peer group.

The P/E Ratio’s Flaws

While this approach typically provides a reasonable valuation range, it is important to understand that our conclusion rests on some important assumptions. The first being that the selected peer group actually contains companies that truly are similar to Delta. The second important assumption is that the selected peer group stocks are being fairly valued by the market.

If the assumptions above do not hold to be true, then the difference in P/E ratios could be due to a variety of factors. For example, if you accidentally compare Delta with lower growth companies, then its P/E multiple would naturally be higher than its peers since investors reward high growth stocks with a higher price.

On the other hand, if the second assumption does not hold true, Delta’s higher multiple may be because our selected comparable companies are being undervalued by the market.

What To Do Next

As a current investor, you may have already conducted fundamental analysis on the company and its stock so its current overvaluation could signal a potential selling opportunity to reduce your exposure to DAL. But keep in mind the P/E ratio’s potential flaws when applying this valuation approach. It is important to note that there are a variety of other fundamental factors that I have not taken into consideration in this article.
