In a leap of faith, Carbonite shrugged off broad market volatility and went public Thursday.

Shares of Carbonite opened at $10.93, above its $10 IPO price. The stock closed at $12.35, up $2.35 or 23.5% on volume of 1.2 million shares.

The online backup company was the first to successfully price its IPO this week. Yesterday, Carbonite sold 6.25 million shares at $10 each, the bottom of its expected $10-$11 price range (which was itself lowered from its prior target of $15 to $17 a share).

Carbonite is offering to sell about 5.4 million shares while some stockholders are providing 883,527 shares. BofA Merrill Lynch and J.P. Morgan are joint bookrunners on the IPO. Other underwriters include William Blair & Co., Canaccord Genuity, Oppenheimer & Co. and Pacific Crest Securities. The underwriters have the option to buy another 937,500 shares.

Carbonite’s IPO comes as the broad market continued to yo-yo. The Dow surged 423.37 points, or 4%, to 11,143.31 Thursday after plunging 520 points Wednesday. The S&P 500 ended up 51.88 points, or 4.6%, to 1,172.64, according to MarketWatch.

Several deals — including WageWorks, WhiteGlove Health and Loyalty Alliance — postponed their IPOs this week due to broad market volatility. Trustwave Holdings on Thursday also chose to delay its deal due to poor market conditions, according to Renaissance Capital.

One other deal managed to price this week, Renaissance Capital says. SandRidge Permian Trust, which has interests in producing and developing wells within the Permian Basis, sold 30 million units at $18 each (below its $19 to $21 range), Renaissance Capital says.
