Electric-car maker Tesla Motors' (NASDAQ:TSLA) second-quarter financial results were worse than analysts were expecting. But investors don't seem to care too much. Shares were trading about flat in after-hours trading at the time of this writing. As Tesla doubles down on future-focused investments such as its Gigafactory and Model 3, the company's big bets on growth continue to capture investor attention.

Here's a review of the quarter's financial results, along with a look at some key points from the shareholder letter.

Quarterly results

Tesla reported a loss of $293 million, or $2.09 per share. On a non-GAAP basis, this loss was $150 million, or $1.06 per share. This non-GAAP loss per share was wider than its $0.57 loss in the prior quarter and its $0.48 loss in the year-ago quarter.

Tesla's revenue was about $1.3 billion. Revenue adjusted to include a $293 million net increase in deferred revenue from indirect leases for its vehicles, as well as from vehicles sold with the company's residual value guarantee, was about $1.6 billion. This compares with adjusted revenue of $1.6 billion in the prior quarter and $1.2 billion in the year-ago quarter.

On average, analysts were expecting Tesla to report non-GAAP EPS of $0.52 and adjusted revenue of $1.63 billion.

Tesla delivered about 14,400 vehicles during the quarter -- a figure it had already reported a few days after the quarter's end. Deliveries were shy of the company's expectations for 17,000 deliveries as Model X production was slowed by supplier shortages. Model X accounted for about 4,600 of these deliveries -- up from 2,400 in the prior quarter.

Key takeaways

Model 3 is on track. Tesla said it has completed the Model 3 design phase and remains on schedule to launch the $35,000 vehicle next year. For the Model 3 program, which Tesla expects to generate $20 billion annually, Tesla has moved on to tooling, production planning, and validation.

"Some Model 3 production equipment is already on line, including initial capacity in our stamping and paint centers," Tesla explained in the company's second-quarter shareholder letter. "Later this year, we plan to begin construction of new Model 3 body and general assembly centers."

Gigafactory on target to reach 35 GWh cell production in 2018. The company's construction of its Gigafacotry, or a battery factory aimed at producing more battery cells than was produced in the entire world in 2013, remains on track with the company's recent accelerated plan to reach a production rate of 35 GWh per year by 2018, or two y ears earlier than initially planned. The Gigafactory pull-ahead was announced not long after Tesla witnessed higher-than-expected demand for the Model 3 when it was unveiled earlier this year.

Tesla reduced its full-year outlook for deliveries. After missing its target for quarterly vehicle deliveries for both Q1 and Q2, the company reduced its outlook for full-year guidance for the metric. Tesla said it expects to deliver 50,000 vehicles during the second half of the year. That would put full-year deliveries at about 79,200 -- short of its initial guidance for 80,000 to 90,000 vehicles in 2016.

Notably, however, 50,000 deliveries in the second half would be a significant jump from Tesla's 29,200 deliveries in the first half. And Tesla insisted that demand for its vehicles supports this level of deliveries:

At the beginning of Q2, we had very few Model X test drive cars in our stores and no refreshed Model S vehicles. Despite not having the refreshed Model S in stores for the full quarter, and not until June for international markets, Model S orders increased year over year. With the addition of Model X orders, total Q2 net new vehicle orders rose 67% from a year ago.

Overall, the quarter's results once again highlight just how focused the company is on growth. Near-term losses mounted as Tesla made significant inroads on plans for growing vehicle sales from 50,000 deliveries during 2015 to its target of 2018 deliveries during 2018.
