Swedish budget fashion retailer Hennes & Mauritz said today that sales rose 4% in November in local currencies from a year earlier.
The figure lagged a mean forecast for a 9% rise in a Reuters poll of analysts.
H&M said in a statement that sales were negatively affected by unseasonably mild weather in North America and many of its large markets across Europe.
Net sales from September to November, H&M's fiscal fourth quarter, totalled 48.7 billion Swedish crowns ($5.76 billion), up from a year-ago 42.6 billion but below the mean forecast of 49.6 billion.
The company is due to publish its full fiscal fourth-quarter earnings report on January 28.
