Company Snapshot
Sunrun Inc. is a leading provider of residential solar and battery storage solutions in the United States, employing over 11,000 people and serving a broad customer base. The company leverages a vertically integrated model to capture value across system design, installation, and long-term service, differentiating itself through direct sales and a robust partner network. Sunrun's strategy focuses on expanding the adoption of distributed solar and storage, positioning the company as a key player in the transition to renewable residential energy.
Foolish Take
Greenvale Capital’s recent $3.9 million sale of Sunrun shares appears to be a portfolio trim following a strong rebound in the stock—rather than souring on the position. The London-based fund reduced its position by 291,438 shares, leaving Sunrun as its largest holding, valued at $231.8 million and representing 18.2% of total AUM.
The timing came just before a third-quarter earnings report that underscored a turnaround in cash generation and balance-sheet strength. The company reported $108 million in cash generation, its sixth consecutive positive quarter, and net income of $16.6 million, reversing an $83.8 million loss a year prior. Revenue, meanwhile, jumped 35% year-over-year to $724.6 million, fueled by a 77% increase in solar energy system sales.
Despite recent volatility, Sunrun’s fundamentals show improving unit economics and disciplined cost control. Greenvale’s smaller but still dominant exposure signals ongoing conviction in the residential solar leader—particularly as the company executes on its storage-first strategy and scales new home-to-grid programs.
