Adidas shares plunged as much as 17% in one of their steepest single-day declines on record, as a jump in marketing spending and a disappointing profit reading eclipsed the German sportswear maker’s decision to raise its longer-term sales forecast.
The sell-off wiped billions of euros from the company’s market value, underscoring how quickly investor sentiment can turn even when a business posts an upbeat revenue outlook. The stock’s drop marked its worst intraday performance in years.
At the heart of the concern was a roughly 30% increase in marketing expenditure, a figure that weighed on margins and cast doubt over the profitability of the company’s turnaround. The heavier spending came as Adidas leaned into high-profile sponsorships, with teams competing in international tournaments wearing the brand’s kits.
Despite these headwinds, Adidas lifted its sales expectations for 2026, signaling management’s confidence in continued demand for its footwear and apparel lines. The upgrade reflects strong momentum in its lifestyle and performance categories, which have anchored a recovery under chief executive Bjorn Gulden.
Investors, however, focused on the gap between top-line strength and bottom-line delivery. The profit shortfall raised questions about whether the ramped-up promotional outlays would translate into sustained earnings growth or simply compress returns in the near term.
The reaction echoes broader turbulence across the athletic-wear sector, where rivals have also faced scrutiny over margins and guidance. Nike endured a sharp market reaction after trimming its own guidance amid slowing sales, illustrating how sensitive the industry has become to any signs of financial strain.
Adidas has spent recent years rebuilding after a costly split from a major celebrity partnership and a subsequent inventory overhang. The company has since cleared much of that stock and returned to growth, buoyed by renewed interest in its classic footwear franchises.
The elevated marketing budget is widely seen as an investment in brand visibility during a crowded sporting calendar. Whether that outlay pays off will likely determine how the market rewards the company in coming quarters.
For now, the divergence between rising sales projections and a softer profit picture has left shareholders uneasy. Analysts will be watching upcoming results closely to gauge whether Adidas can convert its promotional push into durable margin expansion as it heads into a pivotal year.
