Tesla Inc. has been served with a subpoena from the U.S. Securities and Exchange Commission, adding further scrutiny of CEO Elon Musk’s plans to take the company private.
The subpoena came after Musk’s tweet, “funding secured.”
Representatives for the SEC and Tesla declined to comment.
The serving of a subpoena indicates that the inquiry has moved onto a formal stage, which may take months to years finalize.
Tesla’s share price fell down 2.6 percent to $338.69 on Aug. 15, following news of the subpoena, lower than the share price the day prior to Musk’s tweet.
The latest news extended the roller-coaster ride for Tesla investors in recent days, adding to uncertainty about the future course of the company and whether a deal can be done amid growing regulatory complications.

Questions over financing continue to grow
Since Musk’s tweet, it has become clear that neither Musk nor Tesla had the necessary financing set aside for the privatization, drawing skepticism from both investors and analysts, according to CNBC. On Aug. 13, Musk said in a blog on Tesla’s website that he was in discussions with Saudi Arabia’s sovereign wealth fund and other potential backers but that financing was not yet nailed down. Musk also said that the reported amount of more than $70 billion required to privatize Tesla, “dramatically overstate the actual capital raise needed.”Despite the Saudi Fund having over $250 billion in assets, enough to purchase Tesla, many of the fund’s assets are not liquid and readily available cash is limited.
The proposal for Saudi Arabia to finance Tesla’s privatization may prove difficult due to Saudi Arabia’s Public Investment Fund (PIF) being tied up in other investments, and Saudi Arabia’s illiquid market. Assets owned by the PIF cannot be monetized quickly without driving down prices in the local stock market, while selling many of them would conflict with another of the PIF’s declared roles.
In addition, bankers familiar with Saudi Arabia’s Public Investment Fund told Reuters that have not yet seen any signs of the PIF committing to a Tesla deal.
“Any foreign investment in Tesla would at least notionally be of interest to CFIUS,” Joseph Falcone, a partner at Herbert Smith Freehills in New York, told Bloomberg.
Musk tweeted late night on Aug. 13, he was working with Goldman Sachs and private equity firm Silver Lake as financial advisers. However, as of Aug. 14, Goldman was still negotiating its terms of engagement with Musk, according to a person familiar with the matter.
A three-person committee has been formed by Tesla’s board, which will assess a potential buyout by Musk while leaving the door open for other offers.
