Facebook and other companies that went public recently will start reporting quarterly earnings later this month, generally for the July-September quarter.

Zynga Inc., the maker "FarmVille" and other online games, announced last week that it expects a loss for the third quarter due to weak demand for some of its titles. It's also taking a charge related to its acquisition of OMGPop, a mobile game maker, which it bought for $183 million in March. Zynga's stock fell on the next trading day.

Here's a schedule for earnings reports from some tech companies that had IPOs since last year. The companies are all loosely Internet-related, though their businesses vary widely. Dates for some companies, including LinkedIn Corp. and Groupon Inc., are not yet known.

— Oct. 23: Facebook Inc. (first day of trading on May 18, 2012)

— Oct. 24: Zynga Inc. (first day of trading on Dec. 16, 2011)
