SAN FRANCISCO, Aug. 05, 2021 (GLOBE NEWSWIRE) -- Sunrun (NASDAQ:RUN), the nation's leading provider of residential solar, storage and energy services, today announced financial results for the second quarter ended June 30, 2021.

"Consumers are seeking clean, affordable, resilient energy sources now more than ever. This quarter sales volumes accelerated to new records and we delivered record installations in both our direct and channel businesses. We are meeting this need while investing in our differentiated service offering, including virtual power plants and integration with electric vehicles," said Lynn Jurich, Sunrun's Chief Executive Officer and co-founder. "Our incredible team is tackling climate change while building a stronger, more resilient grid that puts customers at the center."

"We remain on track to deliver a break-out year and are increasing our full-year growth guidance to 30%," said Tom vonReichbauer, Sunrun's Chief Financial Officer. "Given the advantages of our broad-reach and multi-channel strategy, our team is capturing the accelerating consumer interest, while executing the ongoing integration of Vivint Solar and navigating a dynamic supply chain environment."

Growth & Market Leadership

The growth opportunity for the solar industry is massive. Today, only 3.5% of the 77 million addressable homes in the US have solar. The US residential electricity market is over $187 billion per year and ongoing utility spending has resulted in escalating retail rates, increasing our value proposition and expanding our addressable market. Households that adopt electric vehicles consume approximately double the amount of electricity, increasing our market opportunity and value proposition even further. In addition to delivering a superior electricity service, we are increasingly working to network our dispatchable solar and battery systems to provide resources to the grid, such as virtual power plants, to also serve the $120 billion annual market for utility capex. These virtual power plants offer greater potential for resiliency and precision than bulky centralized infrastructure.

Owing to network effects and density advantages, increasing operating scale efficiencies, growing brand strength, capital raising capabilities, and advanced product and service offerings, we believe Sunrun will continue to expand our leadership position. Here are a few highlights from the last quarter:

In 2021 Sunrun now expects to accelerate its growth rate to 30%, an increase from the prior guidance of 25% to 30%. This growth is from a baseline scale that's already twice the next competitor. Sunrun's expanding customer value proposition, growing brand strength, differentiated talent brand and increasing competitive advantages are delivering share gains.
Severe weather caused by climate change continues to uncover vulnerabilities with the electric grid's aging infrastructure, leaving millions of people without power. Sunrun has now installed over 23,000 solar and battery systems nationwide, which offer homeowners the ability to power through multi-day outages with clean and reliable home energy. Solar and battery systems also optimize when power is purchased or supplied to the grid, helping manage constraints on the grid during peak times. Installation volumes and attachment rates of batteries have increased again in Q2 to a record level. We continue to expect battery installations to increase more than 100% in 2021 compared to the prior year.
We are delivering increased value to channel partners from our platform. This quarter we set another all-time record in volume in our channel business. Sunrun grew the selective group of partners we work with by over 15% in Q2 compared to the prior quarter. Nearly all of the new partners have agreed to exclusive agreements to sell Sunrun's solar service offering.
Sunrun's new homes business continues to gain momentum and scale, with additional home builders selecting Sunrun as their preferred partner during the second quarter. Our pipeline of new homes continues to expand, spanning hundreds of communities which have been awarded or are already under construction. We grew this segment by more than 75% in the second quarter compared to the prior year, pro-forma for Vivint Solar, and are now working with over 20 of the top 30 homebuilders in California. Sunrun has increased its market share in this segment from less than 5% two years ago to well above 20% today.
Legislators are recognizing that to decarbonize the economy, we must transition more household energy consumption to electricity. In July, Senator Heinrich introduced the Zero-Emission Homes Act which seeks to make household electrification easy and affordable through rebates of up to $10,000 per household for modern, zero emission electric appliances. Efforts to accelerate electrification turbocharge the fight against climate change while also helping to create millions of good-paying jobs across the country. Further home electrification has positive flywheel effects for Sunrun's business, expanding our TAM, increasing the size of home solar and battery systems, and increasing the value of a managed portfolio of distributed energy assets.
Policy makers also remain focused on extending renewable energy incentives as they recognize the importance of investing in clean energy as a way to address climate change, create jobs and improve the resilience of our energy infrastructure. Following the two-year extension of the Investment Tax Credit (ITC) in December 2020, President Biden has proposed a 10-year extension of the ITC, expected to be included in the budget reconciliation package later this year. The ITC has a proven track record of bipartisan support given the economic and environmental benefits.

Innovation & Differentiation

The world has the technologies to move to a decentralized energy architecture today. Home solar and batteries can operate economically at small scale and can therefore be located where energy is consumed, leveraging the built environment instead of relying on expensive, centralized infrastructure whose design specifications do not meet today's weather reality. Sunrun is effectuating this transition through continued business model innovation and a superior customer experience. We provide fixed-rate solar as a service subscriptions, whole-home backup power capabilities, and participation in virtual power plants. We are investing in efforts to further electrify the home, including electric vehicle charging infrastructure and converting gas appliances to electric. These efforts will increase Sunrun's share of the home energy wallet and enhance our value to customers. The following recent developments highlight our innovation and increasing differentiation:

Homes with electric vehicles consume approximately double the amount of electricity. Home solar and batteries are needed to meet this increased strain on the electric system and Sunrun is well positioned to be the provider of these services given our expertise managing and installing at-home energy infrastructure, our national footprint, and reputation as a trusted provider of clean energy services. We continue to innovate and set the stage for increased customer value and electricity usage by building larger systems and offering additional services. In May we announced a partnership with Ford to be the preferred installer for Ford Intelligent Backup Power, Ford's Charge Station and home integration system, debuting with the all-electric F-150 Lightning. Sunrun co-developed the bi-directional inverter technology with Ford that can dispatch power back to the home, and Sunrun has been selected to distribute and install this technology. The F-150 Lightning can serve as a reliable home backup energy source by dispatching power to the home during a power outage event. Through this partnership, customers will also be provided with the opportunity to install a Sunrun solar and battery system on their home, enabling them to power their household with clean, affordable energy and charge their F-150 Lightning with the power of the sun.
Our business development and policy teams are actively educating more utilities and grid operators on the valuable services networked distributed energy resources can provide. Sunrun has already forged 12 virtual power plant opportunities and has continued growing our pipeline. We have over $75 million in expected revenue from grid service opportunities that have been awarded or are in late-stage discussions. These opportunities provide incremental recurring revenue and offer an enhanced customer value proposition while also further differentiating Sunrun's offering from companies that lack the scale, network density, and technical capabilities to serve this market. We estimate that over 10% of geographies we serve today have beachhead virtual power plant opportunities in place, which is expected to expand to over 50% of our geographies in the coming years.
In July, under a program approved by the Hawaii Public Utilities Commission, Hawaiian Electric launched an incentive for homeowners to expand their solar systems and add a battery, or simply to add a battery to an existing solar system. The program aims to procure 50 MWs of capacity to meet the void left by a retiring fossil fuel power plant, further recognizing that distributed solar and batteries are a valuable resource to the grid. The Hawaii Commission is encouraging customers to install batteries so as to keep their own lights on, as well as prevent system-wide blackouts. This is just one more instance proving that clean, distributed energy resources can and should replace fossil fuel power across the United States.
Government leaders and agencies are focusing on ways to accelerate solar adoption by streamlining permitting and interconnection processes. Permitting and interconnection delays can stall residential solar projects by 3 to 6 months and add thousands of dollars of costs to each project. Sunrun has been an early collaborator and champion in helping develop an industry-wide web-based solar permitting tool called SolarAPP. Today, over 30% of our volume is located in areas where local building departments are evaluating SolarAPP or have already adopted online and instantaneous permitting, including testing in parts of Arizona, California, Maryland, Texas and South Carolina. Early results from jurisdictions that have adopted SolarAPP have seen more than a 50% reduction in the time spent to review solar permit applications. In July, the Department of Energy Secretary Granhom stressed the importance of SolarAPP. Funding to accelerate development and adoption was recently included in the latest State of California budget in addition to the recent federal appropriations bill.

ESG Efforts: Embracing Sustainability & Investing in Communities

Sunrun's mission is to create a planet run by the sun and build an affordable energy system that combats climate change and provides energy access for all. We proactively serve all stakeholders: our customers, our employees, the communities in which we operate, and our business and financial partners. Investing in our people and providing meaningful career opportunities is critical to our success. As the country embarks on upgrading infrastructure and rewiring our buildings, the demand for skilled workers will increase substantially. We are focused on developing a differentiated talent brand and providing opportunities to train workers to be part of the clean energy economy. The following recent developments highlight our commitment to sustainability, investing in people, and investing in our communities:

Sunrun's scale and market leadership continues to attract the best talent in the industry. Sunrun has grown its workforce by more than 25% since the beginning of the year, creating well-paying jobs in hundreds of communities across the country, and setting the foundation for accelerated growth.
We remain committed to building a differentiated talent brand. We continue to invest in our people and have expanded the Sunrun Academy efforts to increase career advancement opportunities. As part of this initiative, Sunrun launched a program to further the development of our people whereby all employees have access to an expanded tuition reimbursement program to build skills needed for their career. This program will help us train the next leaders, especially with critical in-demand skills like electrical work. In Q2 we expanded our partnerships with the Department of Defense's SkillBridge program to provide opportunities for servicemen and women returning from active duty while also establishing a new relationship with the Home Builders Institute to provide industry career pathways to transitioning service members.
In April, Sunrun unveiled sustainability goals in its fourth annual Impact Report. These goals include offsetting more than 600 million metric tons of carbon emissions from the systems we will deploy over the next decade. We also set a goal to achieve net zero carbon emissions from our operations by 2040, to transition our vehicle fleet to one third electric or hybrid within five years, and to deploy at least 500 megawatts of solar to lower-income people across the country by 2030.
The solar systems we deployed in Q2 are expected to prevent the emission of 4.1 million metric tons of CO2 over the next thirty years. Over the last twelve months, Sunrun's systems are estimated to have offset more than 2.5 million metric tons of CO2.

Key Operating Metrics

In the second quarter of 2021, Customer Additions were 26,110, including 21,894 Subscriber Additions. As of June 30, 2021, Sunrun had 599,743 Customers, including 520,891 Subscribers.

Annual Recurring Revenue from Subscribers was $747 million as of June 30, 2021. The Average Contract Life Remaining of Subscribers was 17.2 years as of June 30, 2021.

Subscriber Value was $34,519 in the second quarter of 2021 while Creation Cost was $28,945. Net Subscriber Value was $5,574 in the second quarter of 2021. Net Subscriber Margin was lower than in prior periods given our accelerating sales activities and the upfront timing of cost recognition, as many costs are incurred ahead of installation volume recognition. The company estimates that Net Subscriber Margin would be $8,039 pro-forma for adjusting for these growth-related timing effects.

Total Value Generated was $122 million in the second quarter of 2021.

Gross Earning Assets as of June 30, 2021 were $8.6 billion. Net Earning Assets were $4.5 billion, which includes $858 million in total cash, as of June 30, 2021.

Solar Energy Capacity Installed was 185.6 Megawatts in the second quarter of 2021. Solar Energy Capacity Installed for Subscribers was 157.1 Megawatts in the second quarter of 2021.

Networked Solar Energy Capacity was 4,238 Megawatts as of June 30, 2021. Networked Solar Energy Capacity for Subscribers was 3,708 Megawatts as of June 30, 2021.

Outlook

Management now expects Solar Energy Capacity Installed growth to be 30% for the full-year 2021, pro-forma for Vivint Solar, an increase from the prior guidance range of 25% to 30% growth.

Total Value Generated is now expected to be in a range of $700-750 million for the full-year 2021, which has been adjusted primarily because of the effects of accelerating growth and timing of cost recognition.

Management continues to expect cost synergies derived from the acquisition of Vivint Solar to be approximately $120 million in run-rate synergies by the end of 2021.

Second Quarter 2021 GAAP Results

Total revenue was $401.2 million in the second quarter of 2021, up $219.9 million, or 121%, from the second quarter of 2020. Customer agreements and incentives revenue was $219.5 million, an increase of $113.4 million, or 107%, compared to the second quarter of 2020. Solar energy systems and product sales revenue was $181.7 million, an increase of $106.5 million, or 142%, compared to the second quarter of 2020.

Total cost of revenue was $328.9 million, an increase of 124% year-over-year. Total operating expenses were $542.9 million, an increase of 105% year-over-year.

Included in operating costs for the second quarter of 2021 were $12.4 million of non-recurring expenses, including $9.1 million in expenses related to litigation along with $3.4 million in restructuring costs related to the acquisition of Vivint Solar. Operating costs also include stock-based compensation expenses of $43.5 million in the second quarter of 2021.

Consistent with purchase accounting standards under GAAP, the fair value of outstanding equity awards for Vivint Solar employees was reevaluated upon the closing of the acquisition, which resulted in a step-up of the value of such awards, which will result in an increase to non-cash stock-based compensation expense until such awards have fully vested. Additionally, the value of Solar Energy Systems was recorded based on a fair value assessment, which was approximately $1.1 billion higher than the book value at the date of the acquisition, and will result in additional non-cash depreciation expense over the estimated useful life of the assets, partially offset by a write-off of Vivint Solar's Cost to Obtain Customer Agreements.

Net loss attributable to common stockholders was $41.2 million, or $0.20 per share, in the second quarter of 2021.

Financing Activities

As of August 5, 2021, closed transactions and executed term sheets provide us expected tax equity and project debt capacity to fund over 430 megawatts of Solar Energy Capacity Installed for Subscribers beyond what was deployed through the end of the second quarter of 2021.

Definitions

Deployments represent solar energy systems, whether sold directly to customers or subject to executed Customer Agreements (i) for which we have confirmation that the systems are installed on the roof, subject to final inspection, (ii) in the case of certain system installations by our partners, for which we have accrued at least 80% of the expected project cost, or (iii) for multi-family and any other systems that have reached our internal milestone signaling construction can commence following design completion, measured on the percentage of the system that has been completed based on expected system cost.

Customer Agreements refer to, collectively, solar power purchase agreements and solar leases.

Subscriber Additions represent the number of Deployments in the period that are subject to executed Customer Agreements.

Customer Additions represent the number of Deployments in the period.

Solar Energy Capacity Installed represents the aggregate megawatt production capacity of our solar energy systems that were recognized as Deployments in the period.

Solar Energy Capacity Installed for Subscribers represents the aggregate megawatt production capacity of our solar energy systems that were recognized as Deployments in the period that are subject to executed Customer Agreements.

Creation Cost represents the sum of certain operating expenses and capital expenditures incurred divided by applicable Customer Additions and Subscriber Additions in the period. Creation Cost is comprised of (i) installation costs, which includes the increase in gross solar energy system assets and the cost of customer agreement revenue, excluding depreciation expense of fixed solar assets, and operating and maintenance expenses associated with existing Subscribers, plus (ii) sales and marketing costs, including increases to the gross capitalized costs to obtain contracts, net of the amortization expense of the costs to obtain contracts, plus (iii) general and administrative costs, and less (iv) the gross profit derived from selling systems to customers under sale agreements and Sunrun's product distribution and lead generation businesses. Creation Cost excludes stock based compensation, amortization of intangibles, and research and development expenses, along with other items the company deems to be non-recurring or extraordinary in nature.

Subscriber Value represents the per subscriber value of upfront and future cash flows (discounted at 5%) from Subscriber Additions in the period, including expected payments from customers as set forth in Customer Agreements, net proceeds from tax equity finance partners, payments from utility incentive and state rebate programs, contracted net grid service program cash flows, projected future cash flows from solar energy renewable energy credit sales, less estimated operating and maintenance costs to service the systems and replace equipment, consistent with estimates by independent engineers, over the initial term of the Customer Agreements and estimated renewal period. For Customer Agreements with 25 year initial contract terms, a 5 year renewal period is assumed. For a 20 year initial contract term, a 10 year renewal period is assumed. In all instances, we assume a 30-year customer relationship, although the customer may renew for additional years, or purchase the system.

Net Subscriber Value represents Subscriber Value less Creation Cost.

Total Value Generated represents Net Subscriber Value multiplied by Subscriber Additions.

Customers represent the cumulative number of Deployments, from the company's inception through the measurement date.

Subscribers represent the cumulative number of Customer Agreements for systems that have been recognized as Deployments through the measurement date.

Networked Solar Energy Capacity represents the aggregate megawatt production capacity of our solar energy systems that have been recognized as Deployments, from the company's inception through the measurement date.

Networked Solar Energy Capacity for Subscribers represents the aggregate megawatt production capacity of our solar energy systems that have been recognized as Deployments, from the company's inception through the measurement date, that have been subject to executed Customer Agreements.

Gross Earning Assets is calculated as Gross Earning Assets Contracted Period plus Gross Earning Assets Renewal Period.

Gross Earning Assets Contracted Period represents the present value of the remaining net cash flows (discounted at 5%) during the initial term of our Customer Agreements as of the measurement date. It is calculated as the present value of cash flows (discounted at 5%) that we would receive from Subscribers in future periods as set forth in Customer Agreements, after deducting expected operating and maintenance costs, equipment replacements costs, distributions to tax equity partners in consolidated joint venture partnership flip structures, and distributions to project equity investors. We include cash flows we expect to receive in future periods from state incentive and rebate programs, contracted sales of solar renewable energy credits, and awarded net cash flows from grid service programs with utilities or grid operators.

Gross Earning Assets Renewal Period is the forecasted net present value we would receive upon or following the expiration of the initial Customer Agreement term but before the 30th anniversary of the system's activation (either in the form of cash payments during any applicable renewal period or a system purchase at the end of the initial term), for Subscribers as of the measurement date. We calculate the Gross Earning Assets Renewal Period amount at the expiration of the initial contract term assuming either a system purchase or a renewal, 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 utility power prices.

Net Earning Assets represents Gross Earning Assets, plus total cash, less adjusted debt and less pass-through financing obligations, as of the same measurement date. Debt is adjusted to exclude a pro-rata share of non-recourse debt associated with funds with project equity structures along with debt associated with the company's ITC safe harboring facility. Because estimated cash distributions to our project equity partners are deducted from Gross Earning Assets, a proportional share of the corresponding project level non-recourse debt is deducted from Net Earning Assets, as such debt would be serviced from cash flows already excluded from Gross Earning Assets.

Annual Recurring Revenue represents revenue from Customer Agreements over the following twelve months for Subscribers that have met initial revenue recognition criteria as of the measurement date.

Average Contract Life Remaining represents the average number of years remaining in the initial term of Customer Agreements for Subscribers that have met revenue recognition criteria as of the measurement date.

Positive Environmental Impact from Customers represents the estimated reduction in carbon emissions as a result of energy produced from our Networked Solar Energy Capacity over the trailing twelve months. The figure is presented in millions of metric tons of avoided carbon emissions and is calculated using the Environmental Protection Agency's AVERT tool.

Positive Expected Lifetime Environmental Impact from Customer Additions represents the estimated reduction in carbon emissions over thirty years as a result of energy produced from solar energy systems that were recognized as Deployments in the period. The figure is presented in millions of metric tons of avoided carbon emissions and is calculated using the Environmental Protection Agency's AVERT tool.
