Pandora Media garnered $234.9 million in its initial public offering, selling 14.7 million shares at $16 a piece, reports Lee Spears for Bloomberg. The company originally offered shares at $10 to $12. The company currently has a market value of just over $2.6 billion, or around 19 times last year’s sales. Pandora generates 87% of its sales through advertisements that specifically target users, and the company also sells subscriptions for ad-free listening.

“There’s pent-up demand for high-growth, exciting business models,” remarked Scott Billeadeau, a fund manager at Fifth Third Asset Management in Minneapolis. “After LinkedIn, there’s definitely some chasing going on.” [Will ETF Join IPO Party?]
