Horizon Pharma goes public at $9

Horizon Pharma ($HZNP) went public this morning, pricing 5.5 million shares at $9 a share. That's a little below the $10 to $12 range that it had hoped for, but not too bad considering some of the biotech IPOs that have floated at far bigger discounts so far this year. Horizon has also granted the underwriters a 30-day option to purchase up to an additional 825,000 shares at the initial public offering price to cover overallotments. Release
