Let's see what the numbers say about Delta.

Mar 25, 2014 at 5:13PM

Investors love stocks that consistently beat the Street without getting ahead of their fundamentals and risking a meltdown. The best stocks offer sustainable market-beating gains, with robust and improving financial metrics that support strong price growth. Does Delta Air Lines, (NYSE:DAL) fit the bill? Let's take a look at what its recent results tell us about its potential for future gains.

What we're looking for
The charts you're about to see tell Delta's story, and we'll grade the quality of that story in several ways:

  • Growth: are profits, margins, and free cash flow all increasing?
  • Valuation: is share price growing in line with earnings per share?
  • Opportunities: is return on equity increasing while debt to equity declines?
  • Dividends: are dividends consistently growing in a sustainable way?

What the numbers tell you
Let's look at Delta's key statistics:

How we got here and where we're going
Delta takes off with the wind at its back here, grabbing seven of nine possible passing grades. The company barely missed out on another pass in revenue growth, and its net income surge left free cash flow in the dust -- both of these metrics could produce passing grades next year, which would give Delta a shockingly unexpected (for an airline) passing grade. Meanwhile, the company's shareholders have enjoyed strong growth over the past few quarters, and the stock has hit new peaks since the last major airline meltdown. Does that mean Delta will keep outperforming in the future? Let's dig a little deeper to find out.

Delta reported market-topping revenue and earnings per share for its fourth quarter, thanks to impressive domestic and international growth coupled with lower fuel prices. Moreover, the company has also slashed its debt load and recently initiated a dividend and a share repurchase program. Fool contributor Mark Holder notes that the company plans to produce at least $5 billion in operating cash flow this year, which will result in roughly $2.5 billion in free cash flow after investing back into the business. Delta already proved it could do that in 2013, as it reached $5 billion in operating cash flow and $2.1 billion in free cash flow for the year.

Delta still holds $9.1 billion in aircraft purchase commitments, of which $6.4 billion will be due over the next five years. That's far lower than the commitments of peers United Continental (NYSE:UAL) and American Airlines (NASDAQ:AAL) -- these two carriers will buy $23.9 billion and $35.9 billion worth of new planes, respectively. You can see on the chart below just how much this matters, as it wouldn't take much more in purchase commitments to drop Delta down into negative free cash flow territory -- buying eight or nine new Boeing 787s would be enough.

DAL Free Cash Flow (TTM) Chart

DAL Free Cash Flow (TTM) data by YCharts.

Last month, Delta reported a 4% year-over-year increase in passenger revenue per available seat-mile, or PRASM, despite (or perhaps because of) thousands of flight cancellations due to Winter Storm Leon. The increase in PRASM resulted from a staggering 21% increase in midwinter travel to Latin America due to inclement weather in the U.S., which might very well be a one-time situation. Delta's fuel prices are expected to decline 8% year over year, and since this is always the largest expense for airlines, the situation is bound to beef up the bottom line. The company also continues replacing 50-seat regional jets with larger and more cost-effective planes. However, Fool contributor Adam Levine-Weinberg points out that Delta, United, and regional airlines Republic Airways and SkyWest are struggling with new FAA pilot regulations that demand 1,500 hours of flight experience for commercial airline co-pilots, a massive bump from last year's requirement of just 250 hours.

Delta will also expand its footprint in Seattle to challenge the dominance of Alaska Air (NYSE:ALK), part of its overall strategy to bring more connecting traffic in-house (Alaska Air formerly managed much of this traffic in Seattle). The company plans to add new or expanded services for 10 routes out of Seattle, reducing a reliance on Alaska Air to get connecting traffic to its international flights. However, Alaska Air has its own expansion plans, and will launch a series of new routes out of Salt Lake City, which could put further pressure on profit margins for already-competitive routes.

Putting the pieces together
Delta Air Lines has many of the qualities that make up a great stock, but no stock is truly perfect. Digging deeper can help you uncover the answers you need to make a great buy -- or to stay away from a stock that's going nowhere.

To be perfectly clear, this is not a get-rich action that my Foolish colleagues and I came up with. But we wouldn't argue with the approach.

A 2015 Business Insider article titled, "11 websites to bookmark if you want to get rich" rated The Motley Fool as the #1 place online to get smarter about investing.

"The Motley Fool aims to build a strong investment community, which it does by providing a variety of resources: the website, books, a newspaper column, a radio [show], and [newsletters]," wrote (the clearly insightful and talented) money reporter Kathleen Elkins. "This site has something for every type of investor, from basic lessons for beginners to investing commentary on mutual funds, stock sectors, and value for the more advanced."

Our mission at The Motley Fool is to help the world invest better, so it's nice to receive that kind of recognition. It lets us know we're doing our job.

Whether that's helping the entirely uninitiated overcome their fear of stocks all the way to offering clear and successful guidance on complicated-sounding options trades, we want to provide our readers with a boost to the next step on their journey to financial independence.

Articles and beyond

As Business Insider wrote, there are a number of resources available from the Fool for investors of all levels and styles.

In addition to the dozens of free articles we publish every day on our website, I want to highlight two must-see spots in your tour of

For the beginning investor

Investing can seem like a Big Deal to those who have yet to buy their first stock. Many investment professionals try to infuse the conversation with jargon in order to deter individual investors from tackling it on their own (and to justify their often sky-high fees).

But the individual investor can beat the market. The real secret to investing is that it doesn't take tons of money, endless hours, or super-secret formulas that only experts possess.

That's why we created a best-selling guide that walks investors-to-be through everything they need to know to get started. And because we're so dedicated to our mission, we've made that available for free.

If you're just starting out (or want to help out someone who is), go to, drop in your email address, and you'll be able to instantly access the quick-read guide ... for free.

For the listener

Whether it's on the stationary exercise bike or during my daily commute, I spend a lot of time going nowhere. But I've found a way to make that time benefit me.

The Motley Fool offers five podcasts that I refer to as "binge-worthy financial information."

Motley Fool Money features a team of our analysts discussing the week's top business and investing stories, interviews, and an inside look at the stocks on our radar. It's also featured on several dozen radio stations across the country.

The hosts of Motley Fool Answers challenge the conventional wisdom on life's biggest financial issues to reveal what you really need to know to make smart money moves.

David Gardner, co-founder of The Motley Fool, is among the most respected and trusted sources on investing. And he's the host of Rule Breaker Investing, in which he shares his insights into today's most innovative and disruptive companies ... and how to profit from them.

Market Foolery is our daily look at stocks in the news, as well as the top business and investing stories.

And Industry Focus offers a deeper dive into a specific industry and the stories making headlines. Healthcare, technology, energy, consumer goods, and other industries take turns in the spotlight.

They're all informative, entertaining, and eminently listenable ... and I don't say that simply because the hosts all sit within a Nerf-gun shot of my desk. Rule Breaker Investing and Answers contain timeless advice, so you might want to go back to the beginning with those. The other three take their cues from the market, so you'll want to listen to the most recent first. All are available at
