(Bloomberg) -- Nikola Corp.’s internal review of claims about its technology concluded the startup and its founder made several inaccurate statements, marking a break with the company’s previous denials of misleading communications with the public.

The electric-vehicle maker’s probe found nine statements made by the company and its founder and former chairman, Trevor Milton, were wholly or partially inaccurate, according to a regulatory filing made public Thursday.

Nikola commissioned the law firm Kirkland & Ellis to conduct the review after a short seller’s report in September accused the company and its founder of misleading investors. The startup had repeatedly denied the allegations against it and Milton, who stepped down shortly after short seller Hindenburg Research published the report and the company’s share price plummeted.

The accusations prompted inquiries by the U.S. Securities and Exchange Commission and Justice Department. Nikola has said it is cooperating with regulators in those investigations.

A company spokesperson declined to comment beyond what was stated in the filing. A representative for Milton, who remains the single largest shareholder in Nikola with a stake of around 22%, also declined to comment.

Details about the probe were first reported earlier by the Financial Times.

Nine Questionable Assertions

The company’s internal review found the questionable assertions -- seven of which were made by Milton and two by Nikola -- were “inaccurate in whole or in part, when made,” according to the filing.

The misleading statements included a December 2016 claim by Milton that one of Nikola’s first prototypes, the Nikola One, was a fully functioning vehicle. Bloomberg News reported in June that Milton had greatly exaggerated the capabilities of the truck and that it could not be driven at the time it was shown publicly because of missing parts, according to people familiar with the matter.

The review also found some of Milton’s assertions in July of last year about the status of Nikola’s technology and its progress in developing prototypes could not be substantiated.

Not all of the allegations made against the company were validated by the review, and in its filing Nikola disputed the notion its entire business was a “intricate fraud” built on dozens of lies, as Hindenburg suggested in its report.

The fallout from the scandal ultimately led the company to curtail its ambitions after setbacks such as a scaling down of a partnership with General Motors Co. and the cancellation of an electric-powered garbage truck program with Republic Services Inc.

Nikola’s chief executive officer, Mark Russell, told analysts on a conference call Thursday the company’s downsized agenda is a better fit. “We now believe Nikola is in the best position the company has ever been to execute on our core business plan.”
