SAN FRANCISCO, March 10, 2016 – 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, 2015.

Fourth Quarter 2015 Operating Highlights

Full Year 2015 Operating Highlights

“Our customer-centric solar as a service business model has proven to be highly scalable even beyond our early expectations,” said Lynn Jurich, chief executive officer of Sunrun. “As industry fundamentals continue to improve, we believe that our consistent focus on customer net present value, and careful management of liquidity, positions us well in 2016 towards our goal to deliver the industry’s most valuable and satisfied customer base.”

Key Operating Metrics  

In the fourth quarter of 2015, MW booked increased to 80 MW from 37 MW in the fourth quarter of 2014 and MW deployed increased to 68 MW from 37 MW in the fourth quarter of 2014. This resulted in 117% year-over-year growth in MW booked and 83% year-over-year growth in MW deployed.

In full year 2015, MW booked increased to 274 MW from 148 MW in full year 2014 and MW deployed increased to 203 MW from 115 MW in full year 2014 (excluding 14.7 MW associated with an opportunistic asset purchase), slightly below our guidance of 205 MW for 2015, primarily due to the closure of the Nevada market. This resulted in 85% MW year-over-year organic growth in MW booked and 76% year-over-year organic growth in MW deployed.

NPV created in the fourth quarter of 2015 was $50.0 million, compared to $49.5 million in the third quarter of 2015, with $160 million of NPV created in full year 2015. Pre-tax project value per watt was $4.50, compared to $4.70 in the third quarter of 2015. Creation cost per watt was $3.64 in the fourth quarter of 2015 compared to $3.75 in the third quarter of 2015.

Estimated nominal contracted payments remaining as of December 31, 2015 totaled $2.4 billion, compared to $1.6 billion as of December 31, 2014, an increase of 51%. Estimated retained value as of December 31, 2015 was $1.5 billion compared to $1.0 billion as of December 31, 2014, an increase of 52%.

Financing Activities

We have sufficient tax equity committed or subject to executed term sheets to fund our growth plans into November.

In January, we closed a $250 million credit facility at an approximate weighted average cost of 4.5%, which meets our expected volume and liquidity needs for the year.  Between the A and B tranches, the advance rate on this facility is approximately 75% of contracted cash flows available for distribution after tax equity dividends.  The initial draw on this facility is a significant factor in our expectation of being approximately cash flow breakeven in Q1 2016.      

Fourth Quarter 2015 GAAP Results

Total revenue grew to $99.6 million in the fourth quarter of 2015 from $60.1 million in the fourth quarter of 2014. In the fourth quarter of 2015, operating leases and incentives revenue grew 41% year-over-year to $29.6 million. Solar energy systems and product sales were $70.1 million in the fourth quarter of 2015, an increase of 79% year-over-year.

Total cost of revenue was $96.9 million, an increase of 72% year-over-year. Total operating expenses were $164.8 million in the fourth quarter of 2015, an increase of 61% year-over-year.

Net loss attributable to common stockholders was $15.0 million in the fourth quarter of 2015, compared to a net loss of $2.8 million in the third quarter of 2015 and a net loss of $26.7 million in the fourth quarter of 2014.

GAAP net loss per share available to common shareholders was ($0.15) per share.

Full Year 2015 GAAP Results

Total revenue grew to $304.6 million in full year 2015 from $198.6 million in 2014. Operating leases and incentives revenue grew 40% year-over-year to $118.0 million. Solar energy systems and product sales were $186.6 million in 2015, an increase of 63% year-over-year.

Total cost of revenue was $280.5 million, an increase of 62% year-over-year. Total operating expenses were $523.8 million in 2015, an increase of 58% year-over-year.

GAAP net loss per share available to common shareholders was ($0.96) per share.

Guidance for Q1 and Full Year 2016

The following statements are based on current expectations. These statements are forward-looking and actual results may differ materially.

For 2016, we expect to deploy approximately 285 MW. We expect our Sunrun built business to grow at a nearly 100% growth rate.

We will continue to target a $1 per watt of NPV across the full year despite compression due to our exit from Nevada and capacity investments to support the doubling of the direct business.  

In Q1, we expect to deploy 56 MW. We have removed approximately 12 MW of backlog from Nevada that would have been deployed in the quarter.

Key Operating Metrics

Definitions

MW Booked represents the aggregate megawatt production capacity of our solar energy systems sold to customers or subject to an executed customer agreement, net of cancellations.

MW Deployed represents the aggregate megawatt production capacity of our solar energy systems, whether sold directly to customers or subject to 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.

Customers refers to residential customers with solar energy systems that are installed or under contract to install, net of cancellations.

Estimated Nominal Contracted Payments Remaining equals the sum of the remaining cash payments that customers are expected to pay over the initial terms of their agreements (not including the value of any renewal or system purchase at the end of the initial agreement term), including estimated uncollected prepayments, for systems contracted as of the measurement date.

Estimated Retained Value represents the cash flows (discounted at 6%) we expect to receive pursuant to customer agreements during the initial agreement term, excluding substantially all value from solar renewable energy credits (“SRECs”) prior to July 1, 2015. It also includes a discounted estimate of the value of the purchase or renewal of the agreement at the end of the initial term.  Estimated retained value excludes estimated distributions to investors in consolidated joint ventures and estimated operating, maintenance and administrative expenses for systems contracted as of the measurement date.  We do not deduct amounts we are obligated to pass through to investors in lease pass-throughs. Estimated retained value under energy contract represents the net cash flows during the initial 20-year term of our customer agreements.  Estimated retained value of purchase or renewal is the forecasted net present value we would receive upon or following the expiration of the initial contract term.

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.  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 retained value, (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 estimated retained value and (iv) finance proceeds from tax equity investors.  Project value includes contracted SRECs.  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 2015.

Creation Costs 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 and (ii) certain sales and marketing expenses under new customer agreements, net of cancellations during the period divided by the related watts booked.

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

NPV equals unlevered NPV multiplied by leased megawatts booked in period.
