Tesla said on Tuesday that the Justice Department had requested documents from the company after its chief executive, Elon Musk, abruptly announced that he had lined up funding to convert the publicly traded electric-car maker into a private company.
The request for information suggests that the Justice Department has opened a preliminary investigation into Mr. Muskâs market-moving Twitter post on Aug. 7 about the potential buyout.
The Justice Department inquiry, along with an intensifying Securities and Exchange Commission investigation into Teslaâs practices and communications, substantially increases the risks facing the embattled company. Tesla already is under intense financial pressure, with its shares down 25 percent since early August, and the government investigations introduce the possibility of costly penalties or other sanctions.
Tesla said in its statement on Tuesday that it received the Justice Departmentâs request last month and âhas been cooperative in responding to it.â The company released the statement after Bloomberg News reported that federal prosecutors had begun an investigation.
The Justice Department inquiry is being handled by the United States attorneyâs office in San Francisco, according to a person familiar with the matter. It is unclear whether the inquiry is criminal or civil or whether it is at such an early stage that the question has not been settled.
While the specific scope of the Justice Department inquiry isnât known, prosecutors in investigations like this one might look at a companyâs accounting practices, the adequacy and accuracy of its public disclosures and whether executives had sought to mislead investors.
Tesla said the Justice Departmentâs request was not a subpoena but rather a âvoluntary request for documents.â The company added: âWe respect the D.O.J.âs desire to get information about this and believe that the matter should be quickly resolved as they review the information they have received.â
Investigators in the S.E.C.âs San Francisco office are examining whether Tesla misled investors about its production goals. They also are looking into Mr. Muskâs tweet, in which he said he had âfunding securedâ to take the company private for $420 a share.
The tweet blindsided Teslaâs board and ignited a rally in Teslaâs shares. It soon became clear that Mr. Musk had not nailed down the billions of dollars in outside funding that would be required for such a deal. Nor had he retained any banks to assist in the fund-raising process.
Mr. Musk said later in August that he was shelving the idea of converting Tesla into a private company.
As part of the investigation, the S.E.C. in the past month has sent subpoenas not only to Tesla but also to financial institutions that it hired to explore the going-private transaction, according to people briefed on the subpoenas. Goldman Sachs and Silver Lake, a large investment firm, both received subpoenas demanding materials about their interactions with Tesla, the people said.
It is not clear whether the Justice Department inquiry is, like the S.E.C.âs, focused on a wide range of issues at Tesla or in particular on the circumstances surrounding Mr. Muskâs Twitter post.
Mr. Musk and the company he helped found have been bouncing from crisis to self-inflicted crisis in recent months.
There have been severe production problems at Teslaâs California plant, and the company is burning through its cash at a rapid clip. Mr. Musk has faced off with many so-called short-sellers, who are wagering that Teslaâs shares will fall. The companyâs chief accounting officer resigned after a month on the job. Mr. Musk appeared to smoke marijuana during a recent video interview. He was sued this week by a British cave rescuer whom Mr. Musk accused of being a pedophile.
As the pressure mounts, Mr. Musk has retained his own lawyers to represent him in the government investigations, separate from the law firms hired by the company and its board.
Lawyers from Hughes Hubbard & Reed â including Roel C. Campos, a former S.E.C. commissioner â are representing Mr. Musk in connection with the S.E.C. investigation, according to three people familiar with the arrangement. Mr. Musk has also hired Steven Farina, a partner at Williams & Connolly who specializes in government investigations and accounting malpractice, to represent him, two of the people said.
A request for documents from a United States attorneyâs office would often be a sign of a criminal investigation. But federal prosecutors sometimes proceed with civil, not criminal, cases. They generally do so when the conduct they are investigating does not clearly violate a criminal statute or when prosecutorsâ main goal is to stop someone from a specific type of behavior. Civil lawsuits also carry a lower burden of proof than criminal cases.
The news of the Justice Department inquiry sent Teslaâs shares down more than 3 percent on Tuesday.
