SAN FRANCISCO, Feb. 21, 2024 (GLOBE NEWSWIRE) -- Sunrun (NASDAQ:RUN), the nation's leading provider of residential solar, storage and energy services, today announced financial results for the fourth quarter and full year ended December 31, 2023.

"Sunrun ended 2023 in a great position and is starting off 2024 with incredible momentum. Our team is driving an increased mix of higher-margin storage offerings and delivering positive Cash Generation in Q4. We are extending our differentiation by not only making clean, affordable and reliable energy accessible to families across America with the most pro-consumer offerings, but by delivering a superior customer experience and service in the industry. Our strong sales activities and market position gives us confidence that installations will grow considerably from Q1 levels," said Mary Powell, Sunrun's Chief Executive Officer. "We are focused on customer lifetime engagement by not only providing the best service for our customers during their multi-decade relationship with us, but by providing additional products and services customers want, including offering early renewals, adding storage to existing systems, and providing additional products. The pilot of our early renewal product is incredibly encouraging and demonstrates how Sunrun is uniquely positioned to benefit from providing customers valuable services beyond their initial subscription agreement."

"We are driving positive Cash Generation by executing on our margin-focused strategy, optimizing our geographic and product mix, and increasing installation labor efficiency. Cash Generation was $11 million in the fourth quarter, and we are reiterating our strong Cash Generation outlook for 2024," said Danny Abajian, Sunrun's Chief Financial Officer. "We have been active in the capital markets, raising more than $3 billion in capital thus far in Q1, largely with non-recourse asset financing and tax equity to support our growth, and proactively extending maturities to maintain a strong and healthy balance sheet. In the fourth quarter, and into 2024, we repurchased approximately $26 million in principal value of our 2026 convertible bonds at a substantial discount to par, driving shareholder value."

Fourth Quarter Updates

Storage attachment rates accelerating: Storage attachment rates on installations reached 45% in Q4, up from 15% at the beginning of year, with 219.7 Megawatt hours installed during the quarter. Recent sales activities are at ~48% nationally, with California exceeding 85% of all new customers including storage with the solar system. Sunrun has now installed more than 90,000 solar and storage systems, representing over 1.3 Gigawatt hours of stored energy capacity.
Strong results from renewal pilot: Sunrun has launched a pilot to offer customers the ability to renew their subscription agreements early and extend the price protection and peace of mind our service provides. Initial results demonstrate strong value creation potential beyond our initial contracts. So far, nearly 75% of the customers reached are eager to renew contracts for >5 years with their current rate escalation or are in the process of evaluating proposals. Only about 25% of customers opted not to renew early at our first attempt of presenting the offer (about 5 years before contract expiration). However, about half of these customers have expressed interest to buy the system outright, explore upsizing their systems with Sunrun with new equipment, or expressed that they might be moving. All of these scenarios provide opportunities for incremental margin for Sunrun. Economics of executed renewals represents >10% higher Gross Earning Assets (GEA) on average compared to what is embedded in our reported metrics (Contracted + Renewal periods). In addition, approximately half of the Renewal GEA would become Contracted-period GEA. We will continue to optimize our customer-offers and approach and learn from this pilot.
Standalone Storage and Retrofit Update: Consistent with the company's strategy to provide customers value beyond their initial subscription agreements, and consistent with our objective to be a leader in storage, Sunrun commenced both standalone storage and retrofit product sales during the fourth quarter. While it's still early days and only available in select areas, orders have been growing rapidly.
Partnership with Lowe's: Today Sunrun announced the company has selected Lowe's as our preferred home improvement retail partner. Sunrun is already staffing stores and generating leads, launching in stores last week. Sunrun representatives began staffing more than 260 Lowe's stores in 10 states, including California, Illinois, and Texas, and are now available to answer questions and guide customers through the process of going solar at their homes. Sunrun determined Lowe's presented a superior, attractive opportunity with considerable strategic alignment.
Strong capital market execution: Sunrun has arranged new capital or extended maturities of existing capital during Q1 to support growth. Sunrun upsized and extended the maturity of its senior non-recourse revolving warehouse facility. The amended facility was expanded by $550 million to $2.35 billion (from $1.8 billion) and the maturity was extended from April 2025 to April 2028. Sunrun also amended and extended the maturity of its recourse working capital facility, extending the maturity from January 2025 to November 2025 (with a springing maturity provision to March 2027, subject to certain conditions). The size was reduced slightly from $600 million to $447.5 million, with an option to upsize the facility to up to $477.5 million prior to September 30, 2024.
SolarAPP+ Update: As a founding member developing the industry-wide web-based solar permitting tool, SolarAPP+, we are pleased to see the growing adoption and benefits in streamlining permitting and interconnection. In California, approximately one third of our installations in the fourth quarter utilized SolarAPP+, up from around 4% at the start of the year. We are seeing a dramatic improvement in cycle times in areas utilizing SolarApp+, providing a 13 day reduction in the cycle times awaiting permits. Reducing cycle times helps reduce ‘soft costs' and improves the homeowners' experience.

Key Operating Metrics

In the fourth quarter of 2023, Customer Additions were 30,005, including 27,000 Subscriber Additions. As of December 31, 2023, Sunrun had 933,275 Customers, including 781,087 Subscribers. Customers grew 17% in the fourth quarter of 2023 compared to the fourth quarter of 2022.

Annual Recurring Revenue from Subscribers was over $1.3 billion as of December 31, 2023. The Average Contract Life Remaining of Subscribers was 17.8 years as of December 31, 2023.

Subscriber Value was $50,302 in the fourth quarter of 2023, an 18% increase compared to the fourth quarter of 2022. Creation Cost was $36,857 in the fourth quarter of 2023.

Net Subscriber Value was $13,445 in the fourth quarter of 2023. Total Value Generated was $363 million in the fourth quarter of 2023. On a pro-forma basis assuming a 7.5% discount rate, consistent with current capital costs, Subscriber Value was $45,304 and Net Subscriber Value was $8,447 in the fourth quarter of 2023. Commencing in the third quarter of 2023, Subscriber Value included benefits obtained from the energy communities ITC adder for systems deployed during the quarter and commencing in the fourth quarter of 2023, Subscriber Value included expected benefits from the low-income communities (LMI) ITC adder awards for systems deployed during the quarter. Subscriber Value does not yet include value we may receive from the domestic content ITC adder and additional value we may obtain from systems that are eligible for LMI adders. These critical ITC adders will make solar more affordable and accessible to a broader consumer population.

Additionally, hardware costs for key items such as modules, inverters and batteries continue to fall based on current procurement activities, and are expected to provide additional benefits of $1,046 in future periods to Net Subscriber Value. While these cost tailwinds do not benefit Q4 deployments, we have provided the impact of the cost benefits we expect to achieve in future periods as we work through higher-cost inventory. Pro-forma for these benefits, at a 6% discount rate, Net Subscriber Value was $15,256 in Q4. Adjusted for an 7.5% discount rate, but including the full ITC adder benefits and cost deflation, pro-forma Net Subscriber Value was $10,258 in Q4.

Gross Earning Assets as of December 31, 2023, were $14.2 billion. Net Earning Assets were $5.0 billion, which included $988 million in Total Cash, as of December 31, 2023.

Cash Generation was $10.9 million in the fourth quarter of 2023.

Storage Capacity Installed was 219.7 Megawatt hours in the fourth quarter of 2023. This represents a 25% sequential increase from the 175.6 Megawatt hours of Storage Capacity Installed in the third quarter of 2023 and 154% year over year increase from the 86.6 Megawatt hours of Storage Capacity Installed in the fourth quarter of 2022.

Solar Energy Capacity Installed was 227.1 Megawatts in the fourth quarter of 2023. Solar Energy Capacity Installed for Subscribers was 208.2 Megawatts in the fourth quarter of 2023.

Networked Solar Energy Capacity was 6,689 Megawatts as of December 31, 2023. Networked Solar Energy Capacity for Subscribers was 5,636 Megawatts as of December 31, 2023. Networked Storage Capacity was 1.3 Gigawatt hours as of December 31, 2023.

The solar energy systems we deployed in Q4 are expected to offset the emission of 4.6 million metric tons of CO2 over the next thirty years. Over the last twelve months, Sunrun's systems are estimated to have offset 3.8 million metric tons of CO2.

Outlook

Storage Capacity Installed is expected to be in a range of 800 to 1,000 Megawatt hours the full-year 2024. This range represents approximately 40% to 75% growth year over year.

Storage Capacity Installed is expected to be in a range of 160 to 170 Megawatt hours in the first quarter of 2024. This range represents approximately 125% to 139% growth year over year.

Solar Energy Capacity Installed is expected to be in a range of approximately 971 to 1,073 Megawatts for the full-year 2024, reflecting a range representing a 5% decline to 5% growth year over year.

Solar Energy Capacity Installed is expected to be in a range of 165 to 175 Megawatts in the first quarter of 2024. This range represents a decline of approximately 23% to 27% from the fourth quarter, as volumes are typically seasonally lower in the first quarter owing to the timing of sales activities and weather-related limitations on installations.

Net Subscriber Value is expected to be sequentially lower in Q1, following typical seasonal patterns owing to fixed cost absorption and timing of sales activities and volume recognition. More favorable cost absorption, an increasing mix of storage, meaningful hardware cost deflation tailwinds and forthcoming ITC adder value is expected to provide material uplift to our Net Subscriber Values in Q2 through Q4 of 2024. Management expects Net Subscriber Value to reach levels during 2024 which exceed the realized amount in the fourth quarter of 2023.

Total Value Generated is expected to grow by over 15% for the full-year 2024 driven by higher Subscriber Values and lower input costs.

Management is reiterating guidance of positive Cash Generation cumulatively from 4Q 2023 through 4Q 2024 and to reach an annualized Cash Generation run-rate of $200 million to $500 million in the fourth quarter of 2024, subject to the assumptions outlined in our accompanying presentation.

Fourth Quarter 2023 GAAP Results

Total revenue was $516.6 million in the fourth quarter of 2023, down $92.6 million, or 15%, from the fourth quarter of 2022. Customer agreements and incentives revenue was $321.6 million, an increase of $79.3 million, or 33%, compared to the fourth quarter of 2022. Solar energy systems and product sales revenue was $195.0 million, a decrease of $171.9 million, or 47%, compared to the fourth quarter of 2022. The increasing mix of Subscribers results in less upfront revenue recognition, as revenue is recognized over the life of the Customer Agreement which is typically 20 or 25 years.

Total cost of revenue was $482.6 million, a decrease of 13% year-over-year. Total operating expenses were $714.1 million, a decrease of 11% year-over-year.

During the fourth quarter of 2023, Sunrun recorded a $58.7 million non-cash charge related to its investment in Lunar Energy. The company recorded a non-cash charge in Other Expenses of $58.7 million or $0.27 per basic share.

Net loss attributable to common stockholders was $350.1 million, or $1.60 per basic and diluted share, in the fourth quarter of 2023. Pro-forma to exclude the non-cash charge in Q4, non-GAAP net loss would have been $291.5 million or $1.33 per diluted share in the fourth quarter of 2023.

Full Year 2023 GAAP Results

Total revenue was $2,259.8 million in the full year 2023, down $61.6 million, or 3%, from the full year 2022. Customer agreements and incentives revenue was $1,186.7 million, an increase of $203.7 million, or 21%, compared to the full year 2022. Solar energy systems and product sales revenue was $1,073.1 million, a decrease of $265.3 million, or 20%, compared to the full year 2022.

Total cost of revenue was $2,096.8 million, an increase of 4% year-over-year. Total operating expenses were $3,080.5 million excluding goodwill impairment, an increase of 3% year-over-year.

During the year, Sunrun recorded a non-cash goodwill impairment charge of approximately $1.2 billion. Due to the decline in our stock price, we wrote down our goodwill from $4.3 billion to $3.1 billion during the third quarter of 2023. The goodwill primarily arose following the stock-for-stock acquisition of Vivint Solar in October 2020, with the majority arising from and determined based on the market capitalizations at the time of the acquisition. The company recorded a non-cash goodwill impairment charge of $1.2 billion, or $5.35 per basic share, in our Consolidated Statement of Operations for the full year 2023, which was reflected in the Company's third quarter results.

Net loss attributable to common stockholders was $1,604.5million, or $7.41 per basic and diluted share for the full year 2023. Pro-forma to exclude the non-cash goodwill impairment charge in Q3, and non-cash loss on an equity investment in Lunar Energy in Q4, non-GAAP net loss would have been $387.8 million or $1.79 per diluted share for the full-year 2023.

Financing Activities

As of February 21, 2024, closed transactions and executed term sheets provide us with expected tax equity to fund approximately 195 Megawatts of Solar Energy Capacity Installed for Subscribers beyond what was deployed through December 31, 2023. As of December 31, 2023 Sunrun also had $577 million available in its non-recourse senior revolving warehouse facility to fund over 211 Megawatts of Solar Energy Capacity Installed for Subscribers, pro-forma to include the upsize and amendment which was closed subsequent to the end of the quarter.

Key Operating and Financial Metrics

The following operating metrics are used by management to evaluate the performance of the business. Management believes these metrics, when taken together with other information contained in our filings with the SEC and within this press release, provide investors with helpful information to determine the economic performance of the business activities in a period that would otherwise not be observable from historic GAAP measures. Management believes that it is helpful to investors to evaluate the present value of cash flows expected from subscribers over the full expected relationship with such subscribers ("Subscriber Value", more fully defined in the definitions appendix below) in comparison to the costs associated with adding these customers, regardless of whether or not the costs are expensed or capitalized in the period ("Creation Cost", more fully defined in the definitions appendix below). The Company also believes that Subscriber Value, Creation Costs, and Total Value Generated are useful metrics for investors because they present an unlevered view of all of the costs associated with new customers in a period compared to the expected future cash flows from these customers over a 30-year period, based on contracted pricing terms with its customers, which is not observable in any current or historic GAAP-derived metric. Management believes it is useful for investors to also evaluate the future expected cash flows from all customers that have been deployed through the respective measurement date, less estimated costs to maintain such systems and estimated distributions to tax equity partners in consolidated joint venture partnership flip structures, and distributions to project equity investors ("Gross Earning Assets", more fully defined in the definitions appendix below). The Company also believes Gross Earning Assets is useful for management and investors because it represents the remaining future expected cash flows from existing customers, which is not a current or historic GAAP-derived measure.

Various assumptions are made when calculating these metrics. Both Subscriber Value and Gross Earning Assets utilize a 6% rate to discount future cash flows to the present period. Furthermore, these metrics assume that customers renew after the initial contract period at a rate equal to 90% of the rate in effect at the end of the initial contract term. 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. Estimated cost of servicing assets has been deducted and is estimated based on the service agreements underlying each fund.

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 (inclusive of acquisitions of installed systems), 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.

Storage Capacity Installed represents the aggregate megawatt hour capacity of storage systems that were recognized as Deployments in the period.

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. The gross margin derived from solar energy systems and product sales is included as an offset to Creation Cost since these sales are ancillary to the overall business model and lowers our overall cost of business. The sales, marketing, general and administrative costs in Creation Costs is inclusive of sales, marketing, general and administrative activities related to the entire business, including solar energy system and product sales. As such, by including the gross margin on solar energy system and product sales as a contra cost, the value of all activities of the Company's segment are represented in the Net Subscriber Value.

Subscriber Value represents the per subscriber value of upfront and future cash flows (discounted at 6%) 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.

Networked Storage Capacity represents the aggregate megawatt hour capacity of our storage systems that have been recognized as Deployments, from the company's inception through the measurement date.

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 6%) 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 6%) 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.

Cash Generation is calculated using the change in our unrestricted cash balance from our consolidated balance sheet, less net proceeds (or plus net repayments) from all recourse debt (inclusive of convertible debt), and less any primary equity issuances or net proceeds derived from employee stock award activity (or plus any stock buybacks or dividends paid to common stockholders) as presented on the Company's consolidated statement of cash flows. The Company expects to continue to raise tax equity and asset-level non-recourse debt to fund growth, and as such, these sources of cash are included in the definition of Cash Generation. Cash Generation also excludes long-term asset or business divestitures and equity investments in external non-consolidated businesses (or less dividends or distributions received in connection with such equity investments).

Annual Recurring Revenue represents revenue arising 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.

Households Served in Low-Income Multifamily Properties represent the number of individual rental units served in low-income multi-family properties from shared solar energy systems deployed by Sunrun. Households are counted when the solar energy system has interconnected with the grid, which may differ from Deployment recognition criteria.

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. The figure is calculated using the most recent published tool from the EPA, using the current-year avoided emission factor for distributed resources on a state by state basis. The environmental impact is estimated based on the system, regardless of whether or not Sunrun continues to own the system or any associated renewable energy credits.

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. The figure is calculated using the most recent published tool from the EPA, using the current-year avoided emission factor for distributed resources on a state by state basis, leveraging our estimated production figures for such systems, which degrade over time, and is extrapolated for 30 years. The environmental impact is estimated based on the system, regardless of whether or not Sunrun continues to own the system or any associated renewable energy credits.

Total Cash represents the total of the restricted cash balance and unrestricted cash balance from our consolidated balance sheet.
