Lululemon shares plunge 17% after sales miss, guidance cut

What happened

Shares of lululemon athletica inc. (ticker: LULU) plunged 17.38% on September 4, 2026, closing at $100.61 after trading at $121.77 the prior session. Trading volume was about 37.2 million shares, more than ten times the stock's average daily volume of roughly 3.4 million.

The drop followed the company's second-quarter earnings report, which showed a decline in net revenue and a cut to its full-year sales and profit guidance. According to The Motley Fool, this was the third time Lululemon lowered its annual outlook in 2026.

TradingView (StockStory) reported that shares fell 17.7% in afternoon trading after the company disclosed the revenue decline and slashed guidance. Both sources confirm the same core facts: weak quarterly results and a reduced full-year forecast.

Company context

lululemon athletica inc. is a Vancouver-based athletic apparel retailer known for its yoga pants, leggings, and other fitness clothing. The company operates stores and sells online across North America and internationally.

The stock's sharp decline reflects investor reaction to the company's financial update. The sources do not explain the specific reasons behind the revenue decline or the guidance cut beyond the company's own report.

What this means

A company's "guidance" is its own forecast for future financial performance, typically including revenue and profit. When a company "cuts guidance," it lowers those forecasts, signaling to investors that it expects weaker results than previously anticipated. Lululemon's third guidance cut of the year suggests ongoing challenges in meeting its sales and profit targets.

Quarterly earnings reports are required disclosures that publicly traded companies file with the SEC. These reports include net revenue, profit, and other financial metrics, and management often uses them to update investors on expected future performance.

A sharp price drop like this one reflects the market's reaction to the news. The sources here do not indicate whether the drop is justified or what might happen next; they only document the event and the company's announcement.
