Nike (NYSE: NKE) delivered what appeared to be a spectacular fourth quarter for fiscal 2026, but a closer look reveals a massive one-time accounting benefit is obscuring a deeply troubled underlying business.

The footwear giant reported fourth-quarter revenue of $11.0 billion, beating Wall Street’s consensus forecast of $10.85 billion despite a 1% decline on a reported basis and a 4% drop on a currency-neutral basis.

Reported diluted earnings per share came in at $0.72, obliterating the analyst consensus estimate of $0.13 by an extraordinary margin that immediately raised eyebrows across the investment community.

Gross margin ballooned by an astonishing 890 basis points to 49.2%, figures that on the surface suggest a corporate giant firing on all cylinders under CEO Elliott Hill’s aggressive “Win Now” restructuring priorities.

Yet the stock barely moved on the news, remaining pinned near its 52-week lows and trading at a price-to-sales multiple of 1.3, a floor not seen in a decade, signaling deep market skepticism about the quality of those results.

The reason for that skepticism is a single line item that changes the entire narrative: Chief Financial Officer Matt Friend disclosed on the earnings call that “in the fourth quarter, we determined that the financial recovery of claims related to incremental tariffs paid under IEEPA had become probable,” resulting in “a one-time benefit of $986 million.”

Strip out that tariff refund, and Nike’s Q4 earnings per share collapse from $0.72 to just $0.20, while gross margin actually declined slightly by 10 basis points to 40.2%, painting a far less flattering picture of the core retail business.

The structural pressures are visible across nearly every key segment, with Nike Direct revenues falling 7% in the quarter and Nike Brand Digital sliding 12%, demonstrating that the company’s high-margin direct-to-consumer pipeline remains under serious strain.

The once-reliable Converse brand suffered an even sharper blow, with revenue collapsing 32% to $244 million in the fourth quarter, adding further weight to concerns that Nike’s broader portfolio is deteriorating faster than management’s turnaround plan can address.

Greater China compounded the anxiety, with regional revenue plunging 12% as domestic competitors continued to erode Nike’s market share in one of the brand’s most strategically critical growth markets.

CEO Elliott Hill pushed back against the pessimistic reading of the results, stating “through our Win Now priorities, we’re elevating the fundamentals of our business,” while acknowledging “we know we’re not living up to our full potential, particularly in NIKE Sportswear and Jordan Streetwear, where sell-through remains challenged.”

Management pointed to a 6% growth in full-year wholesale revenue and a five-quarter growth streak in its core performance running segment as concrete evidence that a genuine operational recovery is taking shape beneath the noise.

However, CFO Friend’s warning that the operating environment grew tougher as the quarter progressed directly undercut that optimism, with Nike projecting revenue could fall in the low to mid-single digits across the next three quarters.

The central question investors must now answer is whether Nike’s underlying business has quietly begun to heal faster than its narrative suggests, or whether the market is correctly anticipating a painful air pocket once the tariff cash evaporates and one-time tailwinds fade entirely.
