• Solar Energy Capacity Installed was 177 Megawatts in Q1, reaching 6.9 Gigawatts of Networked Solar Energy Capacity.
• Net Earning Assets increased to $5.2 billion, including $783 million in Total Cash.
• Sunrun reiterated its guidance of reaching an annualized Cash Generation run-rate of $200 million to $500 million in Q4 2024.
• Total revenue for Q1 2024 was $458.2 million, down 22% from Q1 2023, primarily due to a decrease in solar energy systems and product sales revenue.
• Net loss attributable to common stockholders was $87.8 million in Q1 2024.
• The company executed two securitizations in 2024, raising a total of $591 million.
• Sunrun also upsized and extended the maturity of its senior non-recourse revolving warehouse facility to $2.35 billion and extended the maturity of its recourse working capital facility.

Sentiment

Score: 6

Explanation: While the company exceeded installation targets and achieved record storage attachment rates, the reduction in guidance for Solar Energy Capacity Installed and Total Value Generated, along with the net loss and negative cash generation in Q1, indicate some challenges. The overall sentiment is cautiously optimistic due to the strong growth in storage and positive long-term outlook, but tempered by the near-term headwinds.

Positives

• Exceeded Q1 guidance for both storage and solar installations.
• Strong growth in storage installations and attachment rates.
• Successful capital markets execution with two securitizations and facility extensions.
• Continued growth in customer base and Annual Recurring Revenue.
• Positive environmental impact with systems expected to offset 3.5 million metric tons of CO2 over the next thirty years.
• Successful virtual power plant programs in California and Puerto Rico.
• Increased adoption of SolarAPP+ to reduce cycle times and streamline permitting.

Negatives

• Total revenue decreased by 22% year-over-year.
• Solar Energy Capacity Installed guidance reduced to a range of -15% to flat growth for the full-year 2024.
• Total Value Generated guidance reduced by 5% from prior guidance.
• Net loss attributable to common stockholders of $87.8 million in Q1 2024.
• Cash Generation was negative $311 million in Q1 2024, although it was positive $6 million when adjusted for non-recurring timing and transaction-related costs.
• Temporary but significant working capital investment of approximately $181 million in Q1 due to transition to tax credit sales.
• One-time costs of $107 million associated with new convertible debt issuance and purchase of capped calls.
• Delays in low-income ITC adders for eligible systems, representing $30 million of expected Cash Generation.

Risks

• Dependence on favorable government policies and incentives for solar energy.
• Potential impact of changes in net metering, interconnection limits, and fixed fees.
• Competition from other solar and storage providers.
• Supply chain disruptions and rising costs of raw materials.
• Volatility in interest rates and availability of financing.
• Ability to manage growth and labor constraints.
• Potential impact of macroeconomic conditions and geopolitical events.

Future Outlook

Sunrun expects Storage Capacity Installed to be in the range of 800 to 1,000 Megawatt hours for the full-year 2024, representing 40% to 75% growth year-over-year. Solar Energy Capacity Installed is expected to decline by 15% to flat growth for the full-year 2024. Total Value Generated is expected to grow by over 10% for the full-year 2024. 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.

Management Comments

• We are starting the year with solid momentum in the business as our storage-first, margin-focused strategy is delivering strong results. In the first quarter we beat the high-end of both our storage and solar installation guidance, set new records for storage attachment rates, and delivered another quarter of strong net subscriber values and an increasing mix of subscription services.
• We are confident in strong growth in installation activities through the year as the fundamental demand drivers of our business continue to be robust.
• We remain committed to driving meaningful cash generation as we execute our margin-focused and disciplined-growth strategy.
• While one-time transaction costs and timing related items impacted Cash Generation in Q1, we expect to recover these timing headwinds in Q2.
• We are reiterating our strong Cash Generation outlook for 2024.

Industry Context

Sunrun's strong performance in storage installations and attachment rates highlights the growing trend of pairing solar with storage in the residential market. This trend is driven by increasing customer demand for energy resilience and independence, as well as declining storage costs. Sunrun's virtual power plant programs also demonstrate the increasing role of distributed energy resources in supporting grid stability and reducing reliance on fossil fuels.

Comparison to Industry Standards

• Sunrun's storage attachment rate of 50% is significantly higher than the industry average. For example, Tesla reported a storage attachment rate of around 20% for its residential solar installations in 2023.
• Sunrun's 192% year-over-year growth in Storage Capacity Installed also outpaces the overall market growth rate. According to Wood Mackenzie, the US residential storage market grew by 62% in 2023.
• Sunrun's virtual power plant programs are among the largest in the country. The CalReady VPP, with over 16,000 enrolled customers, is almost twice as large as the PG&E program last year. This compares favorably to other VPP programs, such as those offered by Tesla and Enphase, which typically have fewer enrolled customers.
• Sunrun's adoption of SolarAPP+ is also ahead of the curve. While SolarAPP+ is gaining traction, it is not yet widely adopted by all solar installers. Sunrun's utilization of SolarAPP+ in approximately one-third of its California projects and 14% nationally demonstrates its commitment to streamlining the permitting process.

Stakeholder Impact

• Shareholders: Potential impact on share price due to mixed results and reduced guidance.
• Employees: Continued focus on growth and talent development.
• Customers: Increased availability of solar and storage solutions, potential for lower energy costs and increased energy resilience.
• Suppliers: Potential impact from supply chain disruptions and changes in demand.
• Creditors: Increased debt levels but also successful capital markets execution and facility extensions.

Next Steps

• Recover timing headwinds impacting Cash Generation in Q2.
• Close additional financing structures in Q2 to fully recover working capital investment.
• Continue to execute on storage-first, margin-focused strategy.
• Drive growth in installation activities through the year.
• Monitor and adapt to changes in the legislative and regulatory environment.
• Continue to expand virtual power plant programs.
• Increase adoption of SolarAPP+ to further reduce cycle times.
