Twitter beats earning expectations amid exodus of top executives

Company posts revenues of $502.4m, compared with $312m from a year earlier, but growth remains an issue after Twitter's CEO was forced out in June

Twitter beat expectations - including its own - by a healthy margin on Tuesday, announcing better-than-anticipated earnings even as two more high-profile executives left amid a continuing shakeup. The company's share price rallied 5.36% in after-hours trading.

"Product initiatives we've mentioned in previous calls haven't yet had meaningful impact on growing audience and participation," interim CEO and co-founder Jack Dorsey said on a conference call with investors. "This is unacceptable, and we're not happy about it."
