Management Comments

• "We are delivering the best product and experience for customers, underwriting volumes with strong unit margins, driving cost and efficiency improvements, and growing our generation capabilities as the nation's largest distributed power plant operator, hitting records this summer in providing energy capacity for the grid. This focus resulted in Sunrun setting a new record in the second quarter for Contracted Net Value Creation as we achieved an all time high 70% storage attachment rate." Mary Powell, CEO.
• "Not only is Sunrun providing Americans with the reliable and affordable energy they need to power their lives, we are scaling our generation business, and helping to stabilize the electricity grid while we do it." Mary Powell, CEO.
• "Sunrun is the largest home-to-grid distributed power plant operator in the country, providing critical utility-scale grid services. Just last month our home-to-grid resources were dispatched to avoid rolling blackouts as traditional power plants failed and demand for electricity was peaking." Mary Powell, CEO.
• "We delivered our fifth consecutive quarter of positive Cash Generation and are reiterating our Cash Generation outlook for 2025." Danny Abajian, CFO.
• "Our actions to drive cost efficiencies and value optimization resulted in the strongest Upfront Net Subscriber Value the company has ever reported, expanding our margins by seventeen percentage points compared to the prior year." Danny Abajian, CFO.
• "In addition to growing origination volumes with significantly higher value storage customers, we have reduced Creation Costs by 4% from last year, with improvements in our installation, sales and overhead costs exceeding 10%, and more than offsetting higher equipment costs driven by the higher storage attachment rate." Danny Abajian, CFO.

Industry Context

Sunrun is solidifying its position as a leader in the residential solar and battery storage market, particularly in the rapidly expanding home-to-grid distributed power plant sector. The company's high storage attachment rate of 70% reflects a strong market trend towards energy resilience and independence, driven by increasing grid instability and consumer demand for integrated solutions. Sunrun's active role in providing grid services, such as dispatching home batteries to prevent blackouts during peak demand, positions it at the forefront of the evolving energy landscape where distributed energy resources are becoming critical for grid stability. The focus on cost efficiencies and value optimization, alongside growth in high-value storage customers, indicates a strategic alignment with the maturing residential solar industry's emphasis on profitability and sustainable cash flow generation.

Comparison to Industry Standards

• Sunrun's 70% storage attachment rate is a leading figure in the residential solar industry, likely surpassing many competitors who may have lower rates or primarily focus on solar-only installations, indicating a strong competitive advantage in integrated solutions.
• The company's network of over 130,000 home batteries providing 650 megawatts of peak power for grid support represents a significant virtual power plant operation, a scale that few, if any, other residential solar companies can match, directly contributing to grid stability in a way comparable to traditional utility-scale assets.
• The successful pricing of $1.4 billion in asset-backed securitizations in 2025 at competitive yields (6.37% in July) demonstrates strong investor confidence in Sunrun's project economics and asset quality, potentially outperforming smaller or less established players in securing non-recourse financing.
• The 4% year-over-year reduction in Creation Costs, coupled with over 10% improvements in installation, sales, and overhead costs, suggests superior operational efficiency compared to industry peers who may be grappling with rising input costs or supply chain challenges.

Stakeholder Impact

• Shareholders: Positive impact due to strong financial performance, increased value creation, positive cash generation, and increased guidance, potentially leading to higher share price.
• Customers: Benefit from reliable and affordable energy, advanced outage protection, and greater peace of mind through solar and battery storage systems, including new offerings like the Tesla Electric + Sunrun Flex plan.
• Grid Operators/Utilities: Benefit from Sunrun's home-to-grid dispatchable power plants providing critical grid services, improving reliability, and helping avoid blackouts during peak demand.
• Employees: Positive outlook due to business growth and focus on efficiency, though 'labor constraints' are mentioned as a risk.
• Creditors/Investors in Securitizations: Confidence reinforced by successful securitization transactions and continued paydown of recourse debt.

Next Steps

• Host a conference call for analysts and investors on August 6, 2025, to discuss Q2 2025 results and business outlook.
• Continue efforts to pay down recourse debt, with an expectation to pay down $100 million or more in 2025.
• Continue to raise tax equity and asset-level non-recourse debt to fund growth.
• Ongoing focus on driving cost efficiencies and value optimization.
• Anticipated further dispatches of home batteries to support grids, as exemplified by events in Puerto Rico during July.
