While a few media outlets attributed the weakness in Tesla shares Friday to the smoke session, the stock would soon see more significant headline risk.
Chief Accounting Officer Dave Morton gave his notice on Tuesday, a regulatory filing released today announced. They say his questionable public persona culminated in his dubious claim on Twitter last month that he had "funding secured" to take Tesla private.
Along the way, Musk drew a subpoena from the Securities and Exchange Commission, which already had been scrutinizing the public pronouncements he's made regarding manufacturing goals and sales targets.
"I think you have a responsibility as a CEO to be a role model to young kids and kids in college and young executives, to your employees", Sun Microsystems co-founder Scott McNealy said on Friday during an interview on FOX Business' "Cavuto: Coast to Coast". The stock opened at $260, down just over 7% from its close yesterday.
Tesla has long struggled with high turnover among its senior executive ranks, and its finance team, in particular, has gone through significant tumult lately. He took leave from the company in 2015 but rejoined to work on the Semi truck revealed in November of previous year.
By leaving, Morton walked away from a $10m new-hire equity grant that would have vested over four years.
Taking a puff from a joint - which Rogan said was a blend of tobacco and marijuana, which is legal in California - Musk said he "almost never" smoked.
The company said its accounting functions will be overseen by the chief financial officer and corporate controller.
Some Wall Street analysts are again calling for Tesla to appoint another senior leader for the company to take the pressure off Elon Musk, or rein in his control. He'll take over for Gabrielle Toledano, who told Bloomberg News on Friday that she won't return from a leave of absence.
The vehicle company has struggled to scale up production of its Model 3 sedan, which has been hit by a number of delays, intensifying the pressure on Musk.
"We move carbon from the ground to the atmosphere (and from there into the oceans) is an incredibly risky experiment whose ultimate outcome is unknown", the Tesla chief told Rogan. And now that the technology that underpins Tesla's products has matured, is it time for a more traditional CEO to step in and help the company level-off into a stable and profitable enterprise?
