Customer agreements and incentives revenue was $543.7 million, up 19%, while energy systems and product sales revenue was $326.3 million, up 193%. The company attributed the increase in energy systems and product sales revenue primarily to a third-quarter 2025 transaction under which certain storage and energy systems associated with newly originated Customer Agreements are sold to a third party. GAAP net income attributable to common stockholders was $115.2 million, or $0.48 per basic share and $0.42 per diluted share.

The CFO cited reduced affiliate channel volumes, a delayed ramp in direct sales activities, and modestly higher capital costs than previously forecasted. The company continues to emphasize a storage-first strategy, expanded sales-force productivity, distributed power plant programs, and data-center and grid-edge applications as potential sources of future Cash Generation.
Management, verbatim
The need for affordable, reliable power has never been more evident, and our storage-first offering is meeting it — customers attached batteries at the highest rate in our history this quarter. We are positioning the business for strong growth, bringing on some of the best talent in the industry and scaling deliberately, with a focus on customer experience and asset quality. And as that engine scales, we're aiming to unlock new ways to monetize the network we've already built, from distributed power plant programs to emerging data center and grid edge applications, creating new streams of Cash Generation.
Mary Powell, Chief Executive Officer
We are revising our full-year Cash Generation outlook to $200 million to $375 million, excluding equipment safe harbor investments, reflecting reduced affiliate channel volumes, a delayed ramp in direct sales activities, and modestly higher capital costs than previously forecasted. Customer demand for our offering remains strong, and as our expanded sales force reaches full productivity, we believe that we will exit the year at a robust growth rate and higher unit margins.
Danny Abajian, Chief Financial Officer
