The results

Tesla's 88% year-over-year increase in fourth-quarter revenue was driven primarily by a 79% jump in the company's automotive business, as vehicle production and deliveries climbed 77% and 27% year over year, respectively.

Notably, Tesla's reported revenue benefited from the inclusion of six weeks of SolarCity's operations, since the solar company was acquired in November.

While losses narrowed year over year, the company's Jan. 3-reported "short-term production challenges" associated with its transition to new Autopilot hardware for its vehicles in Q4 weighed on deliveries and made it impossible for Tesla to sustain the profitability it achieved in Q3. The company delivered 22,400 vehicles -- about 3,000 below its initial guidance and down from 24,821 deliveries in the third quarter of 2016.

What management had to say

Tesla was optimistic about Model 3, saying it was on plan for the initial production of the $35,000 vehicle in July and volume production in September. Further, Tesla said it expects Model 3 production to "exceed 5,000 vehicles per week at some point in the fourth quarter and 10,000 vehicles per week at some point in 2018."

Also, Model S and Model X seem to remain in high demand ahead of Model 3. Tesla said fourth-quarter Model S and X orders reached a record high, increasing 49% year over year.

Tesla said its integration of SolarCity's operations is going well, stating that the company is "on track to generate $500M in cash (including growth of non-recourse project financing) by 2019 and achieve the cost synergies we committed to upon acquiring SolarCity." To meet that goal, Tesla is taking the ax to SolarCity's high advertising expenses and will be selling solar products at Tesla stores. In addition, Tesla will continue shifting SolarCity's system sales away from leasing.

Tesla provided more details on how it is already on track with this target:

As evidence that we are on plan, our solar operations added $77 million of cash during the six weeks following the close of the acquisition, with 28% of solar capacity deployed during Q4 sold rather than leased, up from 13% sold in Q3, and up from less than 4% sold in Q4 2015.

For guidance, the company opted to refrain from a full-year outlook, focusing instead on the first half of the year.

We expect to deliver 47,000 to 50,000 Model S and Model X vehicles combined in the first half of 2017, representing vehicle delivery growth of 61% to 71% compared with the same period last year. In addition, both GAAP and non-GAAP automotive gross margin should recover in Q1 to Q3 2016 levels and then continue to expand in Q2 2017.

Further, Tesla says it expects to invest about $2 billion to $2.5 billion in capital expenditures "ahead of Model 3 production."
