- Excerpt from Survey Results:

The first half of 2013 culminated with Q2 representing the strongest quarter for technology and life sciences IPOs in more than 10 quarters. The life sciences sector was especially active, with 18 offerings in the first half of the year. Life sciences IPOs were at the top end of the scale in terms of size of the offering. Zoetis, a wholly owned subsidiary of Pfizer, raised more than $2.2 billion and Quintiles Transnational raised more than $900 million. Life sciences IPOs were also at the lower end in terms of size, with three offerings each raising less than $50 million. The largest technology offering, Tableau Software, raised $250 million.
