Yahoo CEO Marissa Mayer gave birth to identical twin daughters early Thursday morning.
In a tweet, Mayer said that she and her family are "doing great."
The announcement comes amid a tumultuous month for Mayer and Yahoo. The company announced Wednesday it would abandon the planned spin of its stake in Chinese e-commerce giant Alibaba and look into other options.
Mayer appeared on CNBC's "Squawk on the Street" on Wednesday, saying the decision was "prudent" given the uncertainty about whether the deal would be taxed.
