Billionaire entrepreneur Elon Musk said today he was terminating his $44 billion deal for Twitter, saying that the social media company had failed to provide information about fake accounts on the platform.
Shares of Twitter fell 6% in extended trading.
In a filing, Mr Musk's lawyers said Twitter had failed or refused to respond to multiple requests for information on fake or spam accounts on the platform, which is fundamental to the company's business performance.
The Tesla CEO had threatened to halt the Twitter deal unless the company showed proof that spam and bot accounts were fewer than 5% of users who see advertising on the social media service.
Last month, Twitter allowed Mr Musk access to its "firehose", a repository of raw data on hundreds of millions of daily tweets.
Twitter did not immediately respond to a Reuters request for comment.
