Musk expressed reservations about Tesla being publicly traded, and in August 2018 he made a series of tweets about taking the company private, noting that he had “secured funding.” The following month the U.S. Securities and Exchange Commission (SEC) sued Musk for securities fraud, alleging that the tweets were “false and misleading.” Shortly thereafter Tesla’s board rejected the SEC’s proposed settlement, reportedly because Musk had threatened to resign. However, the news sent Tesla stock plummeting, and a harsher deal was ultimately accepted. Its terms included Musk stepping down as chairman for three years, though he was allowed to continue as CEO.
