Elon Musk must step down as Tesla chair and pay a fine after reaching a deal with US regulators over tweets he posted about taking the firm private.
It follows Thursday’s decision by the Securities and Exchange Commission (SEC) to sue Mr Musk for alleged securities fraud.
Under the deal, Mr Musk will remain as Tesla CEO but has to step down as chairman for three years.
Both he and Tesla will also have to pay a USD 20m fine.
The SEC’s chairman Jay Clayton said that he supported the deal, and felt that it was in the best interests of US markets and investors, including the shareholders of Tesla.
"This matter reaffirms an important principle embodied in our disclosure-based federal securities laws," he said.
"Specifically, when companies and corporate insiders make statements, they must act responsibly, including endeavouring to ensure the statements are not false or misleading and do not omit information a reasonable investor would consider important in making an investment decision."
What did he say in the tweets?
The fraud allegation relates to his August tweet in which Mr Musk said he was considering taking electronic car maker Tesla off the stock market and into private ownership.
He wrote he had "funding secured" for the proposal, which would value Tesla at $420 per share. Shares in the company briefly rose after his announcement, but later fell again.
The SEC said those claims were "false and misleading".
"In truth and in fact, Musk had not even discussed, much less confirmed, key deal terms, including price, with any potential funding source," the regulator said.
Mr Musk initially responded to the charges by saying the action was "unjustified" and he acted in the "best interests of truth, transparency and investors".
