I am not worried by the burn either. However, any business must need cushion to overcome unexpected events specially in manufacturing where things may not get resolved like a software patch.
Good catch on $1.5B for the entire year. Even then, having only a few hundred M $$ in the bank is not a good idea come September. I still feel that Tesla is setting up for a Q2 beat and then they will go for a secondary.
oh yeah, pretty sure they'll do a secondary later this year to be able to keep up the pace of the GF development. Maybe they'll say "to complete GF1 and start construction on the European factory and attached GF2". They may wait for X release or reveal though, just to score a few more wins.
