Sunrun Reports Fourth Quarter and Full Year 2018 Financial Results
Added over 50,000 customers in 2018, growing our customer base 29% year-over-year to 233,000
Total deployments of 373 MWs in 2018, an increase of 15% year-over-year
Cash increased $63 million in 2018
Net Earning Assets of $1.4 billion, an increase of 19% year-over-year

SAN FRANCISCO, February 28, 2019, Sunrun (Nasdaq: RUN), the nation’s largest provider of residential solar, storage and energy services, today announced financial results for the fourth quarter and full year ended December 31, 2018.
“Sunrun finished 2018 with another record breaking quarter, and we expect to continue to advance our market share lead in 2019,” said Lynn Jurich, Sunrun’s Chief Executive Officer and co-founder. “We applaud our 233,000 customers’ efforts to help decarbonize America’s energy system. Our vision is to provide our rapidly growing customer base with a superior energy service and to leverage these solar and Brightbox battery assets to provide value to the entire energy system.”
Key Operating Metrics
In the fourth quarter of 2018, MW deployed increased to 115 MW from 85 MW in the fourth quarter of 2017, a 35% year-over-year increase.
In the full year 2018, MW deployed increased to 373 MW from 323 MW in the full year 2017, a 15% year-over-year increase.
Creation Cost per watt was $3.17 in the fourth quarter of 2018, compared to $3.30 in the fourth quarter of 2017. The presentation of Creation Cost for the fourth quarter of 2017 remains as previously reported, as the calculation due to the adoption of the new accounting standards and the resulting recast financials would have resulted in immaterial changes in the Creation Cost for that period.
NPV created in the fourth quarter of 2018 was $116 million, a 28% increase from $91 million in the fourth quarter of 2017. Unlevered NPV per watt in the fourth quarter of 2018 was $1.21.
Gross Earning Assets as of December 31, 2018 were $3.1 billion, up $850 million, or 38% from the prior year. Net Earning Assets as of December 31, 2018 were $1.4 billion, up $222 million, reflecting a 19% increase from the prior year.
Retail Sales Expansion with The Home Depot
Today, the world’s largest home improvement retailer, The Home Depot (NYSE: HD), and Sunrun, the nation’s leading home solar provider, announced an expanded relationship to offer Sunrun’s home solar and battery service at Home Depot stores in 15 states across the nation. This further enhances access to clean, affordable, solar energy for American households.
Financing Activities
As of February 28, 2019, closed transactions and executed term sheets provide us expected project debt capacity into the fourth quarter of 2019 and tax equity capacity well into the third quarter of 2019.

Unless otherwise specified, financial results for both the fourth quarter of 2018 and the fourth quarter of 2017 are presented in this release under Topic 606 and ASC 842. The financial results for the fourth quarter of 2017 and full year 2017 may differ from those previously reported.

Numbers may not sum due to rounding.

(2) 
Net Earning Assets for the period ending December 31, 2017 reflects changes owing to the adoption of new accounting standards.

(3) 
Sunrun records income when it delivers tax benefits to its tax equity investors. Under partnership flip transactions this income is recognized beginning at the time of deployment. In pass-through financing transactions, income is recognized later, upon utility interconnection permission (PTO). Income recognition therefore lags in periods when the company is increasing its use of pass-through financing funds. Until PTO is received for a solar system in a pass-through financing obligation structure, the company records the expected value of tax benefits as a short term pass-through financing obligation, similar to deferred revenue accounting. The amount reflected within short-term pass-through financing obligation was $25.0 million in the fourth quarter of 2018. As such, the pass-through financing obligation used to calculate Net Earning Assets is reduced by $25.0 million.

(4) 
The presentation of Creation Cost for periods commencing with March 31, 2018 reflects changes made to the calculation owing to the adoption of new accounting standards. The presentation of Creation Cost for periods prior to March 31, 2018 remain as previously reported, as the new calculation and resulting recast financials would have resulted in immaterial changes in the Creation Cost for such prior periods.

Exhibit 99.1
sunrun4q2018image.jpg

Definitions
Creation Cost includes (i) certain installation and general and administrative costs after subtracting the gross margin on solar energy systems and product sales divided by watts deployed during the measurement period and (ii) certain sales and marketing expenses under new Customer Agreements, net of cancellations during the period divided by the related watts deployed.
Customers refers to all residential homeowners (i) who have executed a Customer Agreement or cash sales agreement with us and (ii) for whom we have internal confirmation that the applicable solar energy system has reached notice to proceed or “NTP”, net of cancellations.
Customer Agreements refers to, collectively, solar power purchase agreements and solar leases.
Gross Earning Assets represent the remaining net cash flows (discounted at 6%) we expect to receive during the initial term of our Customer Agreements (typically 20 or 25 years) for systems that have been deployed as of the measurement date, plus a discounted estimate of the value of the Customer Agreement renewal term or solar energy system purchase at the end of the initial term. Gross Earning Assets deducts estimated cash distributions to investors in consolidated joint ventures and estimated operating, maintenance and administrative expenses for systems deployed as of the measurement date. In calculating Gross Earning Assets, we deduct estimated cash distributions to our project equity financing providers. In calculating Gross Earning Assets, we do not deduct customer payments we are obligated to pass through to investors in pass-through financing obligations as these amounts are reflected on our balance sheet as long-term and short-term pass-through financing obligations, similar to the way that debt obligations are presented. In determining our finance strategy, we use pass-through financing obligations and long-term debt in an equivalent fashion as the schedule of payments of distributions to pass-through financing investors is more similar to the payment of interest to lenders than the internal rates of return (IRRs) paid to investors in other tax equity structures. We calculate the Gross Earning Assets value of the purchase or renewal amount at the expiration of the initial contract term assuming either a system purchase or a five year renewal (for our 25-year Customer Agreements) or a 10-year renewal (for our 20-year Customer Agreements), in each case forecasting only a 30-year customer relationship (although the customer may renew for additional years, or purchase the system), at a contract rate equal to 90% of the customer’s contractual rate in effect at the end of the initial contract term. After the initial contract term, our Customer Agreements typically automatically renew on an annual basis and the rate is initially set at up to a 10% discount to then-prevailing power prices. Gross Earning Assets Under Energy Contract represents the remaining net cash flows during the initial term of our Customer Agreements (less substantially all value from SRECs prior to July 1, 2015), for systems deployed as of the measurement date.
Gross Earning Assets Under Energy Contract represents the remaining net cash flows during the initial term of our Customer Agreements (less substantially all value from SRECs prior to July 1, 2015), for systems deployed as of the measurement date.
Gross Earning Assets Value of Purchase or Renewal is the forecasted net present value we would receive upon or following the expiration of the initial Customer Agreement term (either in the form of cash payments during any applicable renewal period or a system purchase at the end of the initial term), for systems deployed as of the measurement date.
MW Deployed represents the aggregate megawatt production capacity of our solar energy systems, whether sold directly to customers or subject to executed Customer Agreements, for which we have (i) confirmation that the systems are installed on the roof, subject to final inspection or (ii) in the case of certain system installations by our partners, accrued at least 80% of the expected project cost.
Net Earning Assets represents Gross Earning Assets less both project level debt and pass-through financing obligations, as of the same measurement date. Because estimated cash distributions to our project equity financing partners are deducted from Gross Earning Assets, a proportional share of the corresponding project level debt is deducted from Net Earning Assets.
NPV equals Unlevered NPV multiplied by leased megawatts deployed in period.

NTP or Notice to Proceed refers to our internal confirmation that a solar energy system has met our installation requirements for size, equipment and design.
Project Value represents the value of upfront and future payments by customers, the benefits received from utility and state incentives, as well as the present value of net proceeds derived through investment funds. Specifically, Project Value is calculated as the sum of the following items (all measured on a per-watt basis with respect to megawatts deployed under Customer Agreements during the period): (i) estimated Gross Earning Assets, (ii) utility or upfront state incentives, (iii) upfront payments from customers for deposits and partial or full prepayments of amounts otherwise due under Customer Agreements and which are not already included in Gross Earning Assets and (iv) finance proceeds from tax equity investors, excluding cash true-up payments or the value of asset contributions in lieu of cash true-up payments made to investors. Project Value includes contracted SRECs for all periods after July 1, 2015.
Unlevered NPV equals the difference between Project Value and estimated Creation Cost on a per watt basis.
