Sometimes the perfect financial storm looks like this: a struggling company beats lowered expectations just as a massive pile of short sellers are betting against it. That's exactly what happened to Under Armour, Inc. (UAA) (UA) on Friday, when shares rocketed more than 11% higher after quarterly results collided with one of the market's heaviest short positions.

Under Armour reported third-quarter fiscal 2026 numbers that managed to surprise on the upside, despite what you'd normally call challenging conditions. Revenue fell 5% year-over-year to $1.327 billion, but that still beat the $1.313 billion analysts were expecting. More impressively, adjusted diluted EPS came in at 9 cents versus expectations for a 2-cent loss. The GAAP numbers told a rougher story—diluted loss per share hit $1.01—but markets tend to focus on adjusted figures, and those were solid.

The underlying business continues to face headwinds. Gross margin contracted by 310 basis points to 44.4%, squeezed by higher tariffs, pricing pressures, and an unfavorable mix across channels and regions. The company took $75 million in restructuring charges and posted an operating loss of $150 million, though adjusted operating income managed to stay positive at $26 million. Net loss totaled $431 million, which included a hefty $247 million valuation allowance on U.S. federal deferred tax assets. Strip that out, and adjusted net income was $37 million.

CEO Sounds Cautiously Optimistic

"Our third quarter adjusted operating results exceeded expectations, and despite a few unfortunate, non-recurring impacts, we're encouraged by the progress we're making in the business to reignite brand momentum," said Under Armour President and CEO Kevin Plank.

He added: "In North America, we believe the December quarter marked the most challenging phase of our business reset, and we expect greater stability ahead as we build on this progress globally."

Regional and Category Breakdown

North America remains the trouble spot, with revenue down 10% to $757 million. International markets performed better, rising 3% to $577 million. Within that, EMEA climbed 6%, Latin America surged 20%, but Asia-Pacific fell 5%.

By channel, wholesale revenue dropped 6% to $660 million, while direct-to-consumer declined 4% to $647 million. eCommerce, which represents 38% of DTC revenue, fell 7%.

Product categories showed mixed results. Apparel revenue decreased 3% to $934 million, footwear took a harder hit with a 12% decline to $265 million, and accessories slipped 3% to $108 million.

Balance Sheet Still Healthy

Inventory fell 2% to $1.1 billion, a positive sign for a retailer trying to clean up operations. Cash and cash equivalents stood at $465 million, and the company has $600 million in restricted investments earmarked to repay senior notes due in June 2026. There are no borrowings against its $1.1 billion revolving credit facility. Operating activities generated $257 million in cash over the nine-month period.

Raised Guidance Surprises

Under Armour lifted its full-year adjusted EPS guidance to 10-11 cents from a prior range of 3-5 cents, well above the 5-cent consensus estimate. That's more than doubling expectations, which tends to get investors' attention.

The GAAP EPS outlook was widened to a loss of $1.24 to $1.25, compared with the previous forecast of a 15- to 17-cent loss and versus the 15-cent loss estimate.

On the revenue side, the company now expects about $4.96 billion for the full year, up from the earlier range of $4.91 billion to $4.96 billion, and just above the $4.95 billion Street estimate. Revenue is still projected to decline roughly 4%, and gross margin is expected to contract about 190 basis points, primarily due to higher U.S. tariffs.

The Short Squeeze Factor

Here's where things get interesting. Under Armour had 66.03 million shares sold short, representing a staggering 41.22% of its publicly traded float. That's an exceptionally high level of short interest, meaning a huge chunk of investors were positioned for further downside. When the stock started climbing on better-than-expected results, those shorts likely faced pressure to cover their positions, creating additional buying momentum that amplified the move.

Shares were up 11.46% to $7.00 on Friday following the announcement.
