Nothing material happened? They had said they would be profitable all quarters going forward and then they weren't profitable in Q1. I think Musk also faced a new settlement with the SEC in that timeframe over violating a prior settlement for investor fraud (I think the prior one had terms letting them technically not admit to fraud) being violated.

They also diluted investors with a capital raise they had strongly hinted wouldn't be needed, and at the autonomy day presentation for that raise they made bold predictions about essentially level 5 autonomy by 2020 (seemed like a lie to me and the entire team was restructured a few weeks later: https://electrek.co/2019/05/10/tesla-autopilot-restructuring... ).
