"The now clear incongruence of CEO outlook statements with official company guidance may hurt the perception of management commentary, eroding investor confidence and potentially placing additional pressure on the shares," J.P. Morgan analyst Ryan Brinkman said in a note to clients late Wednesday. "Full year delivery guidance was stated in the release to have been 'reaffirmed' at the prior level of 360,000 to 400,000 units, in our view undermining a key tenet of CEO Elon Musk's legal defense against the SEC — that his February 19 tweet that Tesla will make around 500,000 vehicles in 2019 was not new information needing pre-approval," Brinkman said.
