Tesla, Twitter shares drop on potential legal issues against Musk, coup bid

Shares of Tesla and Twitter have tumbled this week as investors deal with the fallout and potential legal issues surrounding Tesla CEO Elon Musk and his $44 billion bid to buy the social media platform.

Of the two, Musk's electric vehicle company has fared worse, with its stock down almost 16% so far this week to $728. Twitter shares fell 9.5% for the week, closing Thursday at $45.08. Both stocks have taken a bigger hit than the S&P 500, which is down 4.7% for the week.

Along with malaise in the broader markets, investors have had to weigh legal troubles for Musk, as well as the possibility that his acquisition of Twitter could be a distraction from running the world's most valuable automaker.

The Wall Street Journal reported Wednesday that U.S. securities regulators are investigating Musk's tardy disclosure that he had bought more than 5% of Twitter shares. Musk now owns more than 9% of the San Francisco company.

The SEC wouldn't comment, and a message was left for Musk's lawyer.

A lawsuit filed last month by some Twitter shareholders alleges that Musk's stake hit 5% on March 14, so he should have filed forms with the SEC disclosing that by March 24. Instead, Musk didn't make the required disclosure until April 4, hurting less-wealthy investors who sold Twitter stock in the nearly two weeks before he disclosed his stake and drove up the price, the lawsuit alleges.

Also Wednesday, a federal judge in California handed a group of Tesla shareholders a major victory, unsealing his ruling that Musk falsely and recklessly tweeted in 2018 that he had funding secured to take Tesla private when the deal wasn't final. The tweets pushed up Tesla's share price at the time.

The ruling means that jurors in a shareholder lawsuit will start off knowing that the judge has ruled that Musk's tweets were false.

At the time of the Aug. 7, 2018 tweets, Musk was in talks with the Saudi Public Investment Fund about bankrolling the deal. But Judge Edward Chen determined that it wasn't final when Musk tweeted: "Am considering taking Tesla private at $420. Funding secured.

Chen wrote that there was nothing concrete about funding from the Public Investment Fund, and that discussions were clearly preliminary.

"There had been no discussion about what the purchase price would be for a share of stock. Nor had there been any discussion about what percentage of the company the PIF would own or the total amount of money the PIF would contribute, Chen wrote in his ruling.

Musk's lawyers have asked Chen to reconsider, contending that they aren't aware of cases in which a court has taken similar issues out of a jury's hands where the statements were at best ambiguous and were issued in the word-constrained and informal context of posts on Twitter.

The August 2018, tweets already have landed Musk in legal trouble. The SEC brought a securities fraud charge, which Musk and Tesla settled in 2018. Each agreed to pay a $20 million fine and that a company lawyer would review any Musk tweets that could affect the stock price. The SEC is investigating whether Musk has violated that requirement.

Musk recently lost a bid to have the settlement thrown out on grounds that it violated his First Amendment free speech rights.

Since Musk made his $54.20 per share offer to buy Twitter public on April 14, the shares are exactly the same price $45.08. Analysts say that's an indication of investor skepticism that the deal will go through even though Musk has lined up financing. Twitter shares are up 4.3% year to date.

Tesla shares, however, are down 26% since the April 14 offer, partly on fears that Musk will become distracted as Tesla, which is headquartered in Austin, Texas, opens two new factories and deals with supply chain issues. The shares have tumbled more than 30% so far this year.
