The public offering of Pfizer's animal health subsidiary Zoetis raised $2.2 billion on Thursday, making it the largest IPO of a U.S. company since Facebook.
Zoestis' CEO Juan Ramon Alaix said in an interview on CNBC's 'Squawk on the Street' that his company was positioned well to be a public company, with a unique portfolio and strength in emerging markets.
"It's the right time" to be independent from Pfizer, he said. The performance of Zoetis, which was up over 20 percent immediately after trading opened, could wet the appetite for more companies to initial public offering in 2013.
In the U.S. IPO proceeds, excluding Facebook, fell 35 percent in 2012 from a year earlier, according to Thomson Reuters data.
