Management Comments

• "Sunrun is delivering innovative, storage-first energy offerings that protect American families from rising utility costs and an increasingly unreliable power grid. As we continue to scale our network of over one million customers, we are building a distributed power plant that we believe is critical in meeting the nations urgent demand for more power. We are executing on this vital mission from a position of financial strength – generating strong margins and structurally generating cash." Mary Powell, CEO.
• "We exceeded the midpoint of our Cash Generation guidance for the year and are on track for another strong year in 2026. Our disciplined margin management allowed us to generate strong Upfront Net Subscriber Values, representing a 7% margin for the full-year, a 6 percentage point improvement compared to the prior year. We have continued to strengthen our balance sheet, paying down $148 million of recourse debt while increasing our unrestricted cash balance by $248 million in the year." Danny Abajian, CFO.

Industry Context

StockSavvy.ai notes that Sunrun's strong focus on a storage-first strategy and the expansion of its distributed power plant network aligns well with the broader industry trend towards grid decentralization, energy resilience, and the increasing demand for home battery solutions. The partnerships with utilities like PG&E and energy providers like NRG highlight a growing recognition of virtual power plants' role in grid stability and cost management, positioning Sunrun favorably in a rapidly evolving energy landscape.

Comparison to Industry Standards

• Sunrun's record 71% Storage Attachment Rate in Q4 2025 indicates strong market penetration for integrated solar-plus-storage solutions, potentially outperforming competitors focused solely on solar installations.
• The scaling of its distributed power plant to over 100,000 enrolled customers and dispatching nearly 18 GWh of energy demonstrates a leadership position in virtual power plant development, a critical area for grid modernization that many traditional utilities and smaller solar providers are still exploring or in early stages of implementation.
• The 7% Upfront Net Subscriber Value margin for the full year 2025, a 6 percentage point improvement, suggests effective cost management and pricing strategies compared to industry peers who may be struggling with rising installation costs and competitive pressures.
• The joint venture with Hannon Armstrong for up to $500 million in structured equity financing underscores Sunrun's ability to attract significant capital for large-scale projects, a key differentiator in a capital-intensive industry where smaller players might face financing constraints.

Stakeholder Impact

• Shareholders: Positive impact due to strong financial performance (net income turnaround, cash generation), debt reduction, and positive future outlook. Strategic partnerships and capital raises also enhance long-term value.
• Customers: Benefit from innovative storage-first energy offerings, protection from rising utility costs, and improved grid reliability through distributed power plants. Compensation for sharing stored energy in programs like NRG and PG&E.
