It's unlikely to be worse, especially if he's stepping down from DOGE as the rumors seem to be.
Even with all the hate, the new Model Y is now selling, there's going to be newer more affordable models coming out in a few months, which may sell poorly compared to their expectations, but would still boost numbers above a worst quarter situation.
Q1 has the Chinese new year as well, so future quarters will have a boost above Q1 until next Q1
Even the current status and then China alone with the new models could probably prevent a worse situation.
Numerous quarters / years not meeting expectations absolutely. Less deliveries and production than Q1, unlikely.
The SEC had him forcibly removed via settlement as board chair before over the 420 stuff. It's possible (although less given the current Trump admin) that he could lose a shareholder lawsuit over his failure of fiduciary duty to shareholders and force him out of being CEO as well.
Ultimately, a ruling like that would probably prevent him from being CEO of any public company.
