In a sign of very strong demand, yoga-inspired athletic apparel retailer lululemon athletica priced its offering of 18.2 million shares at $18, a whopping 64% premium to its originally proposed $10-$12 range and above its recently upped range of $15-$17 per share. Although lululemon currently operates only 59 locations (primarily in Canada), management sees potential to support 300+ stores in the US, and its store economics are quite impressive: same-store sales grew between 18% and 25% over the last three fiscal years and it generated annual sales per square foot of $1,300-$1,400. Goldman Sachs and Merrill Lynch acted as joint book-running managers for the IPO, and the stock is set to begin trading on the NASDAQ under the ticker symbol "LULU" on Friday.
