So here's my theory of what will happen till next Aug.
Part A, straight from the Q1 letter
1. They said opex will increase slightly in Q2 and "ramp" it up in H2.
2. They guided for 17k deliveries in Q2.
3. 2.5k Powerwall = 16 MWh, total was 25 MWh, making Powerpack 9 MWh. Using ASP $470/kWh and $350/kWh for Wall and Pack, revenue would be 10.7M. Assuming 15% gross margin (TE pack cost, especially for the Powerwall at this early stage could be quite higher than the $190 number), that's 1.6M gross profit.
4. They recorded a loss from operations of 75M.
5. Model X likely to have about -3.9% gross margin in Q1 based on the following:
a) 12420 S and 2400 X
b) Assuming Model S ASP 100k
c) Model X ASP then would be 130k
d) Model S had a gross margin of 26%, which is the average of 2015 excluding Q4 when they added X to the mix
e) Overall gross margin was 20%
Part B, not so wild assumptions
1. Q2 OpEx increases 5%-10%, so 20.9M to 43.8M increase, taking the average 32.3M here.
2. Personally I think they may have even low balled this one. Especially if they are saying Model S orders increasing, and X ramp issues decreasing. But assume they delivered 12k S and 5k X in Q2.
3. Assuming TE rev grows at 70% ("faster than cars"), gross margin increases to 20%, Then gross profit increases to 3.6 M.
4. That brings the gap to 75+[20.9, 43.8]-3.6=[92.3, 115.2]M.
5. Holding the ASP for S and X, and the gross margin for S the same, the Model X needs 14%~17.5% gross margin to bridge that gap. Considering 2013 Q1 (third quarter of first delivery) gross margin for the Model S was 17%, this 14%~17.5% may not be far fetched.
Part C, personal speculations
1. Powertrain for Model 3 completed, design needs another 6-8 weeks, that puts us roughly at the end of Q2.
2. That means test productions will likely to happen in Q3.
3. They are still meeting with suppliers.
4. They are looking for talents in the manufacturing area.
5. They don't direly need to spend big on CapEx in Q2 since there's still a lot of design/planning now.
Part D, my theory
Given the easiness of swinging for a positive EPS in Q2, and they don't need to (or even can't) buy tons of robots because the design still needs time, they may be holding off the capital raise in August, after they release a great ER to minimize the doubts to maximize the share price to minimize the cost of the raise. Between these three months, they would still need to gradually release good news to maintain the stock price. In fact, I think announcing such a radical advance in Model 3 production is effectively a way to defend the stock price. So, I wouldn't really expect a big climb in stock price until August, but neither will it go down a lot.
