Tesla Second Quarter 2019 Update • Cash and cash equivalents of $5.0B; Operating cash flow less capex of $614M • GAAP operating loss of $167M, GAAP net loss of $408M, including $117M of restructuring and other charges • Auto gross margin at ~19% in spite of reductions in vehicle ASP and lower regulatory credit revenue • On track to launch Gigafactory Shanghai by end of 2019 and Model Y by fall of 2020. In the second quarter of 2019, we achieved record deliveries of 95,356 vehicles and record production of 87,048 vehicles, surpassing our previous quarterly records of ~91,000 deliveries and ~86,600 units produced in Q4 of 2018. This is an important milestone as it represents rapid progress in managing global logistics and delivery operations at higher volumes. As a result of this growth and operational improvements, we generated $614 million of free cash flow (operating cash flow less capex) in Q2. Combined with our public offering of equity and convertible bonds (net proceeds of $2.4 billion), we ended the quarter with $5.0 billion of cash and cash equivalents, the highest level in Tesla’s history. This level of liquidity puts us in a comfortable position as we prepare to launch Model 3 production in China and Model Y production in the US. As a result of our strong deliveries and continued progress on cost efficiencies, our GAAP net loss declined significantly compared to Q1. Autopilot and Full Self-Driving Features: As safety has always been a priority for us, Model 3 received the highest ever ratings in the Safety Assist category of Euro NCAP’s new and more stringent testing protocols. New active safety features built on our Autopilot and Full Self-Driving (FSD) hardware and software suite contributed to this achievement. Development of new features continued in Q2 as we launched Navigate on Autopilot in new regions including Europe and China. We are making progress on our next major update: Enhanced Summon, which is currently in our early access program. We are making progress towards stopping at stop signs and traffic lights. This feature is currently operating in “shadow mode” in the fleet, which compares our software algorithm to real-world driver behavior across tens of millions of instances around the world. Our new FSD computer, which is ~21x faster than our previous HW2.5 computer, has been in production since Q2. Model 3: In Q2, Model 3 deliveries reached an all-time record of 77,634. Not only was Model 3 once again the best-selling premium vehicle in the US, outselling all of its gas-powered equivalents combined, this product also gained traction in other markets. In Europe, Model 3 is approaching sales levels of established premium competitors. As we stated previously, more than 60% of Model 3 trade-ins are non-premium brands, indicating a larger total addressable market for this product than initially expected. Now that all current variants of Model 3 are available across North America, Europe and Asia, we are gaining insight into preferred customer trim mix. During the quarter, a majority of orders continued to be for a long-range battery option and the Model 3 average selling price (ASP) was stable at approximately $50,000. At the same time, manufacturing costs continued to decline. The production rate of Model 3 continued to improve gradually throughout the quarter, breaking a monthly record in May and then again in June. All manufacturing equipment in Fremont has demonstrated capability of a 7,000 Model 3 vehicles per week run rate, which we continue to work to increase. We aim to produce 10,000 total vehicles of all models per week by the end of 2019. Model S/X: Model S and Model X production continues to run on a single shift schedule, and we produced over 14,500 vehicles in Q2. Our deliveries increased sequentially to 17,722 as we continue to prioritize inventory reduction (working capital management). As a result, our total new car inventory levels have fallen to just 18 days of sales (including vehicles in transit, on ships and company owned vehicles), compared to the industry’s typical US inventory level of ~70 days of sales. Gigafactory Shanghai continues to take shape, and in Q2 we started to move machinery into the facility for the first phase of production there. This will be a simplified, more cost-effective version of our Model 3 line with capacity of 150,000 units per year – the second generation of the Model 3 production process. Just like in the US, the Model 3 base price of RMB 328,000 is consistent with its gaspowered competitors, even before gas savings and incentives. Given Chinese customers bought well over a half million mid-sized premium sedans last year, this market poses a strong long-term opportunity for Tesla. We are looking forward to starting production in China by the end of this year. Depending on the timing of the Gigafactory Shanghai ramp, we continue to target production of over 500,000 vehicles globally in the 12-month period ending June 30, 2020. Model Y: Preparations for Model Y production in Fremont began in Q2. Due to a significant overlap of components between Model 3 and Model Y, we are able to leverage existing manufacturing designs in the development of the Model Y production facilities. Additionally, we are making progress managing Model Y cost with only a minimal cost premium expected over Model 3. Due to the large market size for SUVs, as well as higher ASPs, we believe Model Y will be a more profitable product than the Model 3. Infrastructure: As our fleet continues to grow, our service and Supercharger capacity continues to expand. In Q2, we added 101 vehicles to our Mobile Service fleet and opened 25 new store and service locations. While our customer fleet size has doubled in the past 12 months, our service losses remained stable year-on-year and service wait times have improved considerably. Supercharger capacity has grown to roughly 1,600 charging locations worldwide. In addition to the number of charging locations, we are also increasing the rate of throughput of vehicles. We expect the average charging session at our powerful V3 Superchargers will drop to around 15 minutes, which will effectively double the overall throughput rate per stall compared to our V2 Superchargers, easily keeping pace with our fleet growth. Energy: Powerwall and Powerpack deployment grew by 81% in the second quarter to a record 415 MWh. Powerwalls are now installed at more than 50,000 sites. Additional cell supply combined with our new module line designed by Tesla Grohmann enabled a step change in energy storage production. Solar retrofit deployments declined sequentially to 29 MW. We are in the process of improving many aspects of this business to increase deployments. OUTLOOK This quarter, we are simplifying our approach to guidance. We are most focused on expanding our manufacturing footprint in new regions, launching new products and continuing to improve the customer experience, while generating and using cash sustainably. Local production and improved utilization of existing factories is essential to be cost competitive in each region. We remain on track to launch local production of the Model 3 in China by the end of the year and Model Y in Fremont by fall of 2020. We are also accelerating our European Gigafactory efforts and are hoping to finalize a location choice in the coming quarters. We are working to increase our deliveries sequentially and annually, with some expected fluctuations from seasonality. This is consistent with our previous guidance of 360,000 to 400,000 vehicle deliveries this year. Additionally, we expect positive quarterly free cash flow, with possible temporary exceptions, particularly around the launch and ramp of new products. We believe our business has grown to the point of being self-funding. We continue to aim for positive GAAP net income in Q3 and the following quarters, although continuous volume growth, capacity expansion and cash generation will remain the main focus. Our 2019 capex is expected to be about $1.5 to $2.0 billion, a reduction from prior guidance. We continue to find opportunities to improve capital efficiency and shift cash outflows to future periods. This estimate includes the development of our main projects, on the timelines referenced, and to expand our Supercharger and service networks. Elon Musk Zachary Kirkhorn Q2 2019 RESULTS Revenue & Gross Margin Automotive revenue ($000) of which regulatory credits Automotive gross margin • • • Change QoQ 44% -49% -125 bp YoY 60% 106% -168 bp Starting this quarter, we are combining disclosure of both ZEV and non-ZEV credits into a single line item. Excluding regulatory credit revenue, automotive gross margin improved by ~200bp (compared to a decrease of 125bp on a GAAP basis). This was in spite of a reduction in ASP as the Model 3 Standard Range Plus was fully introduced in all markets. We continue to make progress reducing the cost of the product, including through volume growth (fixed cost absorption), lowering material cost, reduction of labor hours per vehicle, and reduction of logistics costs. Model S and Model X gross margin were impacted by pricing actions on vehicles with the prior powertrain version. Inventory of these vehicles has decreased materially as we enter Q3. Energy generation and storage revenue ($000) Energy generation and storage gross margin • Three Months Ended June 30, March 31, June 30, 2019 2019 2018 $ 5,376,389 $ 3,723,861 $ 3,357,681 111,219 215,981 54,011 18.9% 20.2% 20.6 % Three Months Ended June 30, March 31, June 30, 2019 2019 2018 $ 368,208 $ 324,661 $ 374,408 11.6% 2.4% 11.8 % Change QoQ 13% 920 bp YoY -20 -2% bp GAAP gross margin of the Energy business in Q2 improved sequentially to ~12% as the reduction in solar retrofit deployments was more than offset by the improved profitability of our energy storage business and seasonality in the solar lease/PPA business. Other Highlights • • • • • Our total GAAP operating expenses remained relatively flat at $1.1 billion in Q2 in spite of 50% quarter-over-quarter growth in vehicle deliveries and the inclusion of $117 million in restructuring and other charges. Service and Other revenue in Q2 increased predominantly due to stronger used car sales and service revenue growth. Service and Other gross margin in Q2 improved to negative 23% due to a lower impact of one-time items as well as reduced losses in the service business. Most importantly, our total service-related cost continues to decline compared to a year ago, in spite of almost doubling the size of our customer vehicle fleet. Interest and Other expenses increased to $202 million in Q2 compared to $123 million in Q1. This increase was mainly caused by currency movements due to a weakening USD and higher interest expense due to our recent convertible debt issuance. Gains attributable to non-controlling interests impacted our income statement negatively by $19 million in Q2 Cash Flow and Liquidity • • • • Our cash position increased to $5.0 billion, due to $2.4 billion in net proceeds from our May 2019 equity and convertible debt offerings, and $614 million of free cash flow. Gigafactory Shanghai will be almost fully funded through local debt. Thus far, we have secured a $510 million credit line from local banks, which should be largely sufficient for the first phase of the factory. Customer deposits declined to $631 million in Q2. This includes an increase in our order backlog offset by a sequential reduction in customer pre-payments (i.e., customers paying more than the minimum deposit) as well as reservation cancellations as order generation has shifted nearly entirely to non-reservation holders. Our capital expenditures were $250 million in Q2, including Gigafactory Shanghai, charging infrastructure and early investments in the Model Y production line. WEBCAST INFORMATION Tesla will provide a live webcast of its second quarter 2019 financial results conference call beginning at 3:30 p.m. PT on July 24, 2019, at ir.tesla.com. This webcast will also be available for replay for approximately one year thereafter. NON-GAAP FINANCIAL INFORMATION Consolidated financial information has been presented in accordance with GAAP as well as on a non-GAAP basis to supplement our consolidated financial results. Our non-GAAP financial measures include non-GAAP gross margin, non-GAAP net income (loss) attributable to common stockholders, non-GAAP net income (loss) attributable to common stockholders on a per share basis, and operating cash flows plus change in collateralized lease borrowing. Management believes that it is useful to supplement its GAAP financial statements with this non-GAAP information because management uses such information internally for its operating, budgeting and financial planning purposes. These non-GAAP financial measures also facilitate management’s internal comparisons to Tesla’s historical performance as well as comparisons to the operating results of other companies. Management also believes that presentation of the non-GAAP financial measures provides useful information to our investors regarding our financial condition and results of operations because it allows investors greater transparency to the information used by Tesla management in its financial and operational decision-making so that investors can see through the eyes of Tesla management regarding important financial metrics that Tesla management uses to run the business as well as allows investors to better understand Tesla’s performance. Non-GAAP information is not prepared under a comprehensive set of accounting rules and therefore, should only be read in conjunction with financial information reported under U.S. GAAP when understanding Tesla’s operating performance.
