Here's a look at how some companies that had initial public offerings of stock since January 2011 are faring. The companies are all loosely Internet-related, though their businesses vary widely.
Feb. 7: Jive Software Inc., which makes Facebook-style social networks for businesses, reports a wider fourth-quarter net loss, weighed by higher expenses even as its revenue grew sharply. Excluding one-time items, Jive reports a loss of 28 cents per share in the latest quarter, surpassing Wall Street's expectations. Jive's first day of trading was on Dec. 13.
Feb. 8: Groupon Inc., reporting for the first time since public trading of its stock began Nov. 4, says its fourth-quarter revenue nearly tripled, but it lost money and its shares fell sharply after hours. Groupon says an unusually high international tax rate hurt the quarter's adjusted results.
Feb. 9: LinkedIn Corp., which began trading publicly on May 19, had a strong fourth quarter, as its income and revenue beat Wall Street's expectations. The online professional-networking service added 14 million members during the quarter, and the results provide further evidence of online networking's popularity and moneymaking potential.
Feb. 14: Online game maker Zynga Inc. reports a net loss in the last three months of 2011, weighed by hefty stock-compensation expenses and other costs. Its adjusted earnings and revenue skidded past Wall Street's expectations, but that wasn't enough to lift the stock of the company. Zynga's first day of trading was on Dec. 16.
Car-sharing service Zipcar Inc. says it posted a $3.9 million fourth-quarter profit, reversing a loss in the same quarter last year. But the company warned that it expects to post a loss and lower-than-expected revenue for the current quarter. Zipcar shares fell. Zipcar began trading publicly on April 14.
Feb. 16: Demand Media Inc., which began trading publicly on Jan. 26, 2011, reports fourth-quarter earnings and outlook for this year that gave investors hope that it is starting to recover from diminished traffic that had stemmed from changes to Google's Internet search formula. The stock jumps 31 percent on the next trading day.
Feb. 22: Angie's List Inc., which began trading publicly on Nov. 17, reports a smaller loss in the fourth quarter as its membership and revenue grew.
March 6: Pandora Media Inc. (first day of trading was on June 15)
