SAN FRANCISCO, March 8, 2017, Sunrun (Nasdaq: RUN), the largest dedicated residential solar company in the United States, today announced financial results for the fourth quarter and full year ended December 31, 2016.

Fourth Quarter 2016 Operating Highlights

Full Year 2016 Operating Highlights

“Our 2016 performance continues to validate our business model. We grew our portfolio of installed solar energy systems by 47% to 879 MW with improving unit-level economics,” said Lynn Jurich, Sunrun’s chief executive officer. “The reach of our multi-channel business model allowed us to gain market share and deliver a valuable service to our customers and our country’s energy infrastructure.”

Key Operating Metrics  

In the fourth quarter of 2016, total MW deployed increased to 77 MW from 68 MW in the fourth quarter of 2015, a 13% year-over-year increase.

In full year 2016, MW deployed increased to 282 MW from 203 MW in full year 2015, a 39% year-over-year increase.

In the fourth quarter of 2016, MW booked were 72 MW, down 13% from the fourth quarter of 2015.

Creation cost per watt was $3.41 in the fourth quarter of 2016 compared to $3.72 in the fourth quarter of 2015. NPV per watt created in the fourth quarter of 2016 was $1.00 compared to $0.78 in the fourth quarter of 2015.

NPV created in the fourth quarter of 2016 was $67 million, a 47% increase from $46 million in the fourth quarter of 2015. Pre-tax project value per watt was $4.41, compared to $4.50 in the fourth quarter of 2015.

Gross earning assets as of December 31, 2016 was $1.8 billion, up $535 million, or 42%, since December 31, 2015. Net earning assets as of December 31, 2016 were $1.0 billion, up $232 million, or 30% from the prior year.

During the fourth quarter, we reviewed our Key Operating Metrics to ensure our reported metrics remain aligned with how we currently operate our business.  Based on our growing operating experience, unique business model and industry trends, we have modified our method for calculating MW Booked and Creation Cost, and replaced Estimated Retained Value and Estimated Nominal Contracted Payments Remaining with Gross Earning Assets and Net Earning Assets. We believe these changes will provide investors with closer leading indicators of performance and trends and are better aligned with our current sales compensation and key operating objectives.

MW Booked are now calculated as sold systems or systems subject to a Customer Agreement for which we have internal confirmation that the system has met our installation requirements for size, equipment and design (which constitutes our definition of reaching notice to proceed, or NTP), net of cancellations. Since NTP occurs closer to installation, there is a meaningfully higher realization of these systems as deployments, and it is less susceptible to reported seasonal fluctuations. Creation Cost is now calculated so that the single component not previously based on either leased or total deployments now will be. The portion of period sales and marketing expenses previously divided by MW Booked is now divided by MW Deployed.

Finally, management believes Gross Earning Assets (which includes only discounted cash flows for deployed systems, rather than systems subject to a Customer Agreement) provides greater clarity and comparability between periods than Estimated Retained Value and Estimated Nominal Contracted Payments Remaining as it excludes the effect of cancellations that occur between the execution of a Customer Agreement and deployment. Prior periods showing both the updated and previous methodology and a summary of the Key Operating Metrics has been included in this release.

Financing Activities

In December 2016, we entered into a strategic partnership with National Grid PLC (“National Grid”), which includes a  national collaborative grid services pilot and a $100 million direct investment by National Grid in a partnership that will own approximately 200 MW of our rooftop solar systems across the U.S. The strategic partnership also includes a joint marketing agreement that will initially target approximately 100,000 single family homes in downstate New York.

As of March 8, 2017, our tax equity pipeline remains robust, with closed transactions and executed terms sheets that provide us runway well into Q4 of 2017. Our current pipeline of back-leverage and project equity provides us runway into Q3 of 2017.

Key Operating Metrics and Financial Metrics

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 represents the net cash flows (discounted at 6%) we expect to receive during the initial 20-year term of our Customer Agreements 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 excludes 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 do not deduct customer payments we are obligated to pass through to investors in lease pass-throughs as these amounts are reflected on our balance sheet as long-term and short-term lease pass-through obligations, similar to the way that debt obligations are presented. In determining our finance strategy, we use lease pass-throughs and long-term debt in an equivalent fashion as the schedule of payments of distributions to lease pass-through 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.

Gross Earning Assets Under Energy Contract represents the net cash flows during the initial (typically 20 year) 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.

9

MW Booked represents the aggregate megawatt production capacity of our solar energy systems, whether sold directly to customers or subject to an executed Customer Agreement, for which we have confirmation that the systems have reached NTP, net of cancellations.

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 Lease Pass-Through Financing Obligation, as of the same measurement date.

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. Project value includes contracted SRECs for all periods after July 1, 2015. Project value does not include cash true-up payments or the value of asset contributions in lieu of cash true-up payments made to investment fund investors, the cumulative impact of which is expected to be immaterial in 2016.

Unlevered NPV equals the difference between project value and estimated creation cost on a per watt basis.
