Tesla Inc. Chief Executive Officer Elon Musk was accused by the Securities and Exchange Commission of misleading investors when he tweeted that he had funding lined up to take the company private.

On August 7, 2018, Musk tweeted to his 22 million Twitter followers that he could take Tesla private at $420 per share (a substantial premium to its trading price at the time), that funding for the transaction had been secured, and that the only remaining uncertainty was a shareholder vote.  The SEC’s complaint alleges that, in truth, Musk had not discussed specific deal terms with any potential financing partners, and he allegedly knew that the potential transaction was uncertain and subject to numerous contingencies. According to the SEC’s complaint, Musk’s tweets caused Tesla’s stock price to jump by over six percent on August 7, and led to significant market disruption.

The Real tweet was:

Am considering taking Tesla private at $420. Funding secured.

— Elon Musk (@elonmusk) August 7, 2018

The agency said Musk fabricated the claim in his August tweet, which sent Tesla shares higher.

“In truth and in fact, Musk had not even discussed, much less confirmed, key deal terms, including price, with any potential funding source,” the SEC said in complaint filed Thursday in Manhattan federal court, less than two months after Musk’s tweet.

The suit seeks an order from a judge barring Musk from serving as an officer or director of a public company, a request often made in SEC lawsuits, as well as unspecified monetary penalties.

Even before the tweets, the SEC was investigating issues at Tesla including its car sales projections. The Justice Department is also looking into whether Musk misled investors, Bloomberg News has reported.

“Musk made his false and misleading public statements about taking Tesla private using his mobile phone in the middle of the active trading day,” the SEC said. “He did not discuss the content of the statements with anyone else prior to publishing them to his over 22 million Twitter followers and anyone else with access to the Internet. He also did not inform Nasdaq that he intended to make this public announcement, as Nasdaq rules required.”
