Sunrun Inc.

Sunrun installs and finances residential solar panels and home batteries. Customers typically pay under long-term leases or agreements to buy the electricity generated by their systems. The company also sells equipment and installed systems, including sales to investors and a noncontrolled venture. Sunrun Inc. trades on the Nasdaq Global Select Market as RUN.

Its financing model is central to understanding the results. Some systems remain in project funds consolidated by Sunrun. Others are sold wholly or partly to investors, bringing revenue forward while Sunrun continues to service the customers. By September 30, 2026, the company had about 1.23 million customers, including 1.06 million subscribers, and a cumulative battery network of roughly 5 gigawatt-hours.

Quarterly operating trends

Q3 2026 revenue grew 52% year over year while subscriber additions fell 24%. Sunrun's direct installation channel grew 9%, offset by a 67% decline in affiliate installations. The company is rebuilding that partner network. Systems and product sales increased to $546 million from $233 million, while customer agreements and incentives grew 13% to $553 million.

About 46% of new subscribers were associated with systems sold wholly or partly to investors, versus about 10% a year earlier. Sunrun's sales to a noncontrolled venture formed in 2026 accounted for $467.5 million of its quarterly revenue. It records its stake in the venture as an equity investment.

Cash flow and the annual target

Over the first nine months of 2026, operating cash flow was $125.8 million, compared with a $518.4 million outflow a year earlier. Investing activities used $1.298 billion, down from $2.091 billion. Project debt and outside investor funding help finance those system investments.

Sunrun's Cash Generation measure includes that project financing and investor funding, subtracts investment cash uses and makes specified adjustments. Its annual guidance excludes net investment in equipment bought ahead to secure tax credits. The November outlook is about $200 million, down from August's $200 million to $375 million range.

On the same equipment-excluded basis, Cash Generation was negative $30.8 million in Q1, positive $45.0 million in Q2 and positive $55.9 million in Q3. That leaves roughly $130 million in Q4 to meet the revised annual goal. Sunrun has not provided that amount as a separate quarterly forecast.

The annual Aggregate Subscriber Value goal also narrowed to about $4.6 billion from $4.6 billion to $4.9 billion. This measure estimates the present value of cash flows attached to new subscribers. Net Subscriber Value per addition fell to $9,462 in Q3 from $13,205 a year earlier as financing costs rose.

Parent borrowing and project debt

At September 30, recourse debt principal was $618.3 million, down from $727.0 million at year-end 2025. It comprised $135.1 million drawn on the working-capital facility and $483.2 million of 4% convertible notes due March 1, 2030. Recourse debt's carrying value after fees and discounts was $610.4 million.

The working-capital facility matures March 1, 2028 and has $321.4 million of commitments. Letters of credit used another $82.4 million. Additional borrowing availability based on existing eligible assets was zero at September 30. Sunrun reported compliance with its debt covenants.

Nonrecourse project debt had $14.845 billion of principal and a $14.660 billion carrying value. These loans are generally repaid from the relevant projects' customer cash flows. Consolidated cash and equivalents of $699.4 million included $398.2 million held in project entities; another $421.9 million was classified as restricted cash. Project assets become available outside those entities only through permitted distributions.

What to check next

The near-term test is cash production in Q4 and the pace of rebuilding affiliate installations. The larger question is whether greater use of system sales can support cash flow while preserving attractive returns on new customers. Management expects positive Cash Generation and installation growth in 2027 and plans to provide formal numerical guidance with its Q4 results in February.
