Southwest Airlines (NYSE: LUV) fell more than 6% the day after it reported its Q2 2026 earnings. Revenue of $8.43 billion came in short of expectations for $8.58 billion. However, adjusted earnings per share (EPS) of 94 cents beat analysts’ forecast of 52 cents.
To be fair, revenue was up 16.4% year over year. This isn’t an airline in trouble. However, the company guided for slower growth for the remainder of the year.
In the upcoming third quarter, Southwest guided for adjusted EPS between 50 cents and 75 cents. That’s below the estimate of 82 cents per share. For the full year, the airline is guiding for adjusted EPS in the range of $3.25 to $4.25 per share, slightly higher on the low end than the estimate of $3.17.
The Guidance Cut Hiding Behind the Headline
Southwest titled its own press release “Earnings Power on Full Display.” That’s the kind of framing that should make investors pause. Buried beneath the celebratory language is a meaningful guidance cut. Just one quarter ago, Southwest was telling investors to expect full-year adjusted EPS of “at least $4.00.” Now the company says $3.25 to $4.25 — a range whose low end sits a full 75 cents below what management was promising in the spring.
Management will point out that the high end of the new range is still above $4.00, and that’s technically true. But when a company widens its guidance range downward rather than narrowing it as the year progresses, that’s usually a tell. It suggests less visibility into the back half, not more. A company genuinely on top of its earnings power narrows its range as certainty increases. It doesn’t stretch the floor lower.
The capacity story tells a similar tale. Southwest now expects full-year capacity growth of approximately 1.5%, down from its prior guidance of 2%. It’s a small trim, but it’s a trim nonetheless, and it arrives at the same moment management is touting “broad demand strength.”
Buybacks Are Doing More Work Than the Business
Here’s the number that should catch a skeptical reader’s eye: net income of $233 million was up just 9.4% year-over-year, but diluted EPS of 47 cents was up 20.5%. How does a company grow its per-share earnings more than twice as fast as its actual profit? Fewer shares.
Weighted average diluted shares outstanding fell from 541 million to 493 million. That’s a nearly 9% reduction, the product of aggressive buybacks funded in part by drawing down the cash pile built during the pandemic-era capital raises.
There’s nothing wrong with buybacks. But when a huge share of your “earnings power” story is actually a “shrinking denominator” story, that’s worth saying out loud. Southwest still has $450 million left on its repurchase authorization, so expect this lever to keep getting pulled through year-end. That’s a convenient way to keep EPS headlines looking better than organic profit growth would justify on its own.
It’s also worth noting that the reported revenue miss wasn’t purely a demand problem. Southwest revised its estimate of how many older flight credits customers will actually redeem, which forced a $285 million downward adjustment to revenue that’s excluded from the adjusted numbers. Strip that out, and adjusted revenue was actually up 20.3%.
The revenue “miss” is partly an accounting quirk rather than a pure demand shortfall. But it also means the headline growth investors are cheering leans on a number that isn’t quite as clean as it looks, either way you slice it.
A Cloudy Outlook Leans Toward Turbulence for LUV
The stock market is not the economy. But if you pay attention, certain companies serve as a better proxy for the consumer than others. Southwest is a low-cost airline that has developed a loyal customer base. The concern is that a high percentage of those customers are in the lower leg of the K-shaped economy.
As investors have heard from other companies like McDonald’s (NYSE: MCD), Walmart (NASDAQ: WMT) and General Mills (NYSE: GIS), those consumers are being more choiceful. And when you hear from Albertson’s (NYSE: ACI) that consumers are cutting back on grocery spending…you can connect the dots.
Southwest can’t be accused of pessimism. But even with discounted fares, it comes down to believing a forecast or your lying eyes. Many consumers aren’t taking vacations this year. Many that do aren’t flying. That’s a headwind.
Oil prices are above $90 per barrel as I write this. It’s likely to be higher before it goes lower. Southwest’s own numbers back this up — fuel expense jumped $889 million year-over-year in the quarter, with cost per gallon up nearly 70% from a year ago. That will have a direct impact on Southwest’s bottom line.
Airlines in general have irregular and lumpy free cash flow. Southwest is no different. Therefore, earnings growth is perhaps the best metric to gauge its fair value.
If Southwest’s forecast is right, investors can expect strong earnings growth in the second half of the year. It generated $1.39 in adjusted EPS through the first two quarters. To hit the low end of its guidance, it would require over 100% EPS growth.
But hitting that number seems to assume a lot of things are going to go right. Geopolitical risks to oil and macroeconomic risks to the consumer at large suggest that not everything will go right.
For all those reasons, you might want to take a vacation from LUV stock. At the very least, let the current selloff run its course, then re-evaluate. By Labor Day, there may be more clarity on jet fuel prices and holiday travel demand. Without that, LUV offers unquantifiable risk for a reward that doesn’t look that enticing.
