SAN FRANCISCO, May 5, 2021 -- Sunrun (Nasdaq: RUN), the nation’s leading provider of residential solar, storage and energy services, today announced financial results for the first quarter ended March 31, 2021.
“This year is on track to be the best in the company’s history. With an accelerating growth rate and expanding market reach, Sunrun is leading the country to a clean energy future,” said Lynn Jurich, Sunrun’s Chief Executive Office and co-founder. “Now is the time for us to move to a distributed energy system to meet the increased demands placed on our energy system from broad-based adoption of electric vehicles and improve the resiliency of our aging energy system.”

“Our momentum in the fourth quarter has continued into 2021,” said Tom vonReichbauer, Sunrun’s Chief Financial Officer. “The Sunrun team delivered seasonal volume records at strong margins, while meeting the demands of our ongoing integration with Vivint Solar. We expect to accelerate our growth even further while improving the value we bring to our partners and customers. Our execution, scale advantages, differentiated service offering, and leading competitive position give us confidence to increase our full-year growth guidance to 25% to 30%.”

Growth & Market Leadership

The growth opportunity for the solar industry is massive. Today, only 3% 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 expects to accelerate its growth rate to 25-30%, an increase from the prior guidance of 20-25%. This growth is from a baseline scale that’s already twice the next competitor, with strong customer margins. Sunrun’s expanding customer value proposition, growing brand strength, differentiated talent brand and increasing competitive advantages are delivering share gains. Sunrun delivered an all-time record Q1 volume in our direct-to-home sales channel, in our channel partner business, and in our home builder business.
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 nearly 20,000 Brightbox systems nationwide, which offer homeowners the ability to power through multi-day outages with clean and reliable home energy. Brightbox also optimizes when power is purchased or supplied to the grid, helping manage constraints on the grid during peak times. Attachment rates of Brightbox batteries have increased again in Q1 to a record level. We continue to expect Brightbox installations to increase more than 100% in 2021 compared to the prior year.

Exhibit 99.1

We are delivering increased value to Channel partners from our platform. This quarter we set an all-time record in volume in our channel business. Sunrun continued to grow the selective group of partners we work with by over 20% in Q1. Nearly all of the new partners have agreed to exclusive agreements to sell Sunrun’s solar service offering.
Sunrun's new home business is starting to scale. We grew this segment by more than 50% in the first quarter compared to the prior year, pro-forma for Vivint Solar, and are working with 20 of the top 30 homebuilders in California. Our pipeline of new homes is at record levels and spans hundreds of communities which have been awarded or are already under construction across the country.
In January, Sunrun issued $400 million of 0% coupon convertible senior notes and entered into a capped call transaction, increasing the effective conversion price to $157.22 per share.
In March, Sunrun closed a $201 million securitization of leases and power purchase agreements at record-low financing costs. The market increasingly recognizes the high quality of residential solar assets and Sunrun’s industry-leading performance, especially over the last year, allowing the company to enjoy yet another step down in capital costs. The securitization consists of a single-tranche of A- rated notes with a $201 million initial balance, representing an 80.0% advance rate. The notes priced at a yield of 2.46%, representing a spread to the benchmark swap rate of 135 bps. This is an improvement in the spread of approximately 40 bps from the securitization issued by Vivint Solar in September 2020, the previous low water mark.
Politicians continue to 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, within the first 100 days of being in office President Biden has proposed a 10-year extension of the ITC as part of his infrastructure plan and has called for significant investments in renewable energy and improving the resilience of our energy system. Further, members of Congress have proposed specific legislation that would extend the ITC for 10 years and make standalone or retrofit storage eligible for the ITC. 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:
We continue to innovate and set the stage for increased customer values by building larger systems and offering additional services. We are actively exploring opportunities for Sunrun to provide value for customers that have adopted electric vehicles and expect to accelerate these partnerships and commercial opportunities in the near future. 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.
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 now 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.

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:

In Q1 Sunrun launched a set of initiatives and programs, under the Sunrun Academy, to expand job opportunities and increase career advancement opportunities. By investing in our people, we can attract and retain the best workforce with the skills needed to electrify homes across the country. 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. The Sunrun Academy will be expanded in the coming months to provide core functional skill training, leadership curriculum and provide more opportunities for apprenticeships and licensing programs.
Sunrun is accelerating efforts to hire those who have served our country. In Q1, Sunrun was selected to be the first national solar company to participate in the Department of Defense’s SkillBridge program. The program provides opportunities to launch careers after returning from active duty, for both servicemen and women. In addition, Sunrun became the first solar company to be approved for the Military Spouse Employment Program (MSEP) to provide opportunities to spouses of our serving servicemen and women. In the first few weeks of approval, we have already hired dozens of transitioning service members and spouses under both programs.
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.
Sunrun continues its commitment to lead the industry on pay equity by upholding the California Equal Pay Pledge and The White House Equal Pay Pledge, as well as providing a wage of at least $15 per hour to all employees. Sunrun established a Human Rights policy, building on Sunrun’s commitment to fair and equitable treatment.
Sunrun is committed to building an inclusive and diverse workforce. As of December 31, 2020, women make up 50% of our executive management team and 44% of our Board of Directors. Nearly one quarter of all Sunrun employees are women. Sunrun is aiming for gender representation parity in director and above roles by 2025 and race/ethnicity representation parity in manager roles by 2025.
The solar systems we deployed in Q1 are expected to prevent the emission of over 3.9 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 2.4 million metric tons of CO2.
Key Operating Metrics

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.

First Quarter 2021 GAAP Results

Note that the following GAAP results include Vivint Solar, unless otherwise stated, and are not presented pro-forma to include Vivint Solar prior to the closing of the acquisition on October 8, 2020.

Total revenue was $334.8 million in the first quarter of 2021, up $124.1 million, or 59%, from the first quarter of 2020. Customer agreements and incentives revenue was $174.6 million, an increase of $75.5 million, or 76%, compared to the first quarter of 2020. Solar energy systems and product sales revenue was $160.2 million, an increase of $48.6 million, or 44%, compared to the first quarter of 2020.

Total cost of revenue was $294.4 million, an increase of 73% year-over-year. Total operating expenses were $513.3 million, an increase of 88% year-over-year.

Included in operating costs for the first quarter of 2021 were $2.2 million of non-recurring expenses, primarily restructuring and deal costs related to the acquisition of Vivint Solar. Operating costs also include stock-based compensation expenses of $78.0 million in the first quarter of 2021. In the first quarter, cash outflows related to capped call transactions, debt discounts, expenses related to the issuance of the convertible notes, and non-recurring integration related expenses were approximately $43 million.

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 $23.8 million, or $0.12 per share, in the first quarter of 2021.

Financing Activities


Exhibit 99.1

As of May 5, 2021, closed transactions and executed term sheets provide us expected tax equity and project debt capacity to fund over 540 megawatts of Solar Energy Capacity Installed for Subscribers beyond what was deployed through the end of the first quarter of 2021.

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.
