Under Armour Didn't Miss Athleisure. It Sold Its Brand to Costco Mexico to Hit a Number.

Somewhere around 2016, the most prestige-hungry athletic brand in America was quietly stacking its merchandise on the shelves of Costco stores in Mexico. Not as a strategy. As a release valve. The growth target said 20% a year, the orders weren't there, and the gap between the two had to go somewhere — so it went to discount channels, off the books of brand equity and onto the books of revenue. The official story would later be that Under Armour fumbled the athleisure wave. The truer story is that the brand was being sold for parts to make a number, years before anyone in Baltimore drew up a lifestyle deck.

The popular autopsy goes like this: Lululemon and Nike turned gym clothes into a lifestyle, and Under Armour, stuck selling performance gear to athletes, slept through the boom. Under Armour missed the athleisure pivot. It didn't miss a pivot. It destroyed the thing a pivot would have needed — a desirable brand — to chase a growth rate it had promised the market it could keep forever.

The number that ate the company

Under Armour was a genuine rocket. Founded in 1996 in a Georgetown rowhouse, public on the NASDAQ in 2005 — where the stock doubled on its first day of trading — and past $1 billion in annual revenue by 2010.¹⁰ By the time Kevin Plank stood on the 2016 earnings call calling it a year of 'record revenue and earnings,' wholesale was up 19% to $3.1 billion and direct-to-consumer up 27%, with North America up 16% for the year.² On the surface, a company in full flight.

Underneath, the engine was running on a single setting. According to deposition testimony from the company's own CFO, Chip Molloy, the culture had organized itself around one man's appetite. 'Many people in the company were obsessed with pleasing Kevin, and Kevin's desire was 20% revenue growth.'¹ That is the whole mechanism in one sentence. A 20% target, repeated year after year, is not a goal — it's a compounding demand. To hold it, you eventually have to manufacture demand that doesn't exist. Court records describe exactly that: executives pulling sales forward from future quarters and liquidating product through discount retailers, Costco's Mexican stores among them, to keep the line going up.¹

Here is the cruelty of dumping product to make a number: it works exactly once, and it costs you the asset that made the number worth making. A performance brand lives or dies on scarcity and aspiration. Every pallet that lands in a discount aisle teaches the customer that the logo is not premium, that the price on the wall is fiction, that waiting for a markdown is the smart move. The growth target wasn't borrowing from next quarter. It was borrowing from the brand.

The crack appeared before athleisure was even on the table

The timeline is the tell. The first sign of structural trouble wasn't a missed fashion trend — it was North America, the home market, turning negative. In the first quarter of 2017, North American revenue declined 1%, the first year-over-year drop, as new distribution failed to offset business lost to retail bankruptcies.³ That's the moment the plateau began. Under Armour did not announce its 'live' lifestyle and athleisure category until November 2022 — more than five years later.⁹ By the time the pivot existed, an industry analyst was already noting that the brand 'still lacks the clarity and desirability of stronger brands like Lululemon.'⁹

Run the counterfactual the title implies. Suppose Under Armour had launched a polished lifestyle line in 2017 instead of 2022. It would have been launching a premium-priced aspirational product from a logo customers were increasingly finding at discount prices. You cannot charge Lululemon money for a brand the market has been trained to wait out. The pivot didn't fail because it was late. It would have failed early, too, because the discounting that funded the growth number had already poisoned the one ingredient an athleisure play actually requires: desirability.

The $365 million the apps cost on the way out

The growth obsession didn't only express itself through discounting. It also went shopping. Under Armour spent roughly $710 million assembling a connected-fitness empire — MapMyFitness in 2013, then MyFitnessPal for $475 million and Endomondo for $85 million in 2015.⁶ The logic was seductive: turn a vast base of app users into a captive funnel of apparel buyers. It was, in other words, another way to manufacture growth — bolt on users and call them future customers.

The conversion never came. In 2020, Under Armour sold MyFitnessPal to Francisco Partners for $345 million — $130 million below what it had paid — and shut Endomondo down entirely.⁶ An app strategy meant to feed the core business instead drained capital out of it, and the brand was no more desirable for having owned a calorie tracker. The pattern is identical to the discounting: reach for a shortcut to the growth number, and pay for it later in the currency that matters.

But wasn't this just a bad fashion bet?

The fair objection is that plenty of performance brands rode out the athleisure shift, and maybe Under Armour was simply caught with the wrong product DNA at the wrong moment — too technical, too gym, too male — and would have struggled regardless of any growth target. There's something to it. Brand DNA is real, and Under Armour's was forged in compression shirts, not lifestyle. But the objection mistakes a contributing factor for the root. A technical brand can move upmarket and adjacent — Nike has done it for decades — provided it still carries the aspiration to charge for. The thing that made the move impossible wasn't Under Armour's heritage. It was that the heritage had been sold cheap to hit quarterly targets, and an analyst could see the desirability gap the moment the lifestyle line launched.⁹ The product DNA was a headwind. The growth obsession was the wreck.

The bill kept arriving long after Plank first stepped down in 2019 — a departure that came not as a clean succession but against the backdrop of a 2017 shareholder lawsuit alleging the company inflated its share price, with court documents describing Plank sharing confidential financial data with a journalist on a private phone.⁸ He returned as CEO in 2024 to a company still unwinding the era.⁸ Revenue fell for three straight fiscal years — $5.9 billion in FY2023 down to $4.97 billion in FY2026, a 15.9% slide from peak.⁴ FY2026 closed with a $496 million GAAP net loss.⁵ Even the Stephen Curry partnership, the closest thing to a genuine cultural asset Under Armour had built, ended in November 2025 — Curry took sole ownership, the split cost Under Armour $69.7 million in non-cash termination charges, and by June 2026 the Curry Brand had signed a ten-year deal with China's Li-Ning instead.⁷

Under Armour spent a decade answering the wrong question. The question was never 'how do we win athleisure?' — it was 'why was there nothing left to win it with?' And the answer was sitting on a discount shelf in Mexico the whole time. A brand is the one asset you can spend without noticing, because nothing on the income statement records the sale. Under Armour set a number it loved more than its name, and the market gave it both for a while. Then it took the number back and kept the name's reputation as the fee. The athleisure boom didn't pass Under Armour by. Under Armour had already mortgaged the seat at the table to make a quarter.
