The company has a collection of more than 20 million licensed photos, illustrations, and videos. Investor’s interest in Shutterstock increased after Carlyle Group LP (NASDAQ:CG) agreed to acquire Getty Images for $3.3 billion.

Shutterstock Chief Executive Officer and founder Jon Oringer said he declined offers from entities interested in buying the company. He said, “I’ve had lots of opportunities to do whatever I want to do at Shutterstock, and now we have more flexibility to grow.”

Kythera Biopharmaceuticals Inc (NASDAQ:KYTH) sold 4.4 million shares at $16 per share. The company raised $70.4 million in IPO. The company plans to use the funds from its public offering to pay for the late-stage clinical studies for its double-chin treatment, called ATX-101.

The result of the five IPOs was inspiring, since the IPO market had been tepid for several months. The failure of Facebook’s Inc (NASDAQ:FB) IPO brought a negative impact to the IPO market.
