24 PE-backed U.S. companies have successfully gone public this year, raising a total of $4.7 billion, according to the PitchBook Platform. This is an improvement over the 29 companies that went public during all of 2009, but the average IPO size last year was almost double 2010's average. The largest IPO this year was the June IPO of Oasis Petroleum, which raked in $588 million and represented a partial exit for EnCap Investments. In 2009, there were 5 bigger offerings, the largest being the $1.09 billion Hyatt Hotels IPO, which represented partial exits for GS Capital Partners and Madrone Capital. As the IPO market continues to be a harsh environment for PE, expect several firms to opt for other methods of exiting portfolio companies or to continue to delay IPOs in hopes of better days.
