Investment Analysis

Sunrun
RUN
Pros
- Sunrun has shown strong revenue growth in 2025 with a 9% year-over-year increase in Q2 and a 15% year-over-year increase in subscribers, now nearly 942,000.
- The company benefits from long-term subscriber contracts (20 to 25 years) creating stable, recurring revenue streams.
- Sunrun is positioning itself as a key provider for AI-driven power demands, having signed agreements to supply distributed power plants to electricity providers amid rising AI data center energy needs.
Considerations
- The imminent expiration of the federal solar tax credit at the end of 2025 risks sharply reducing consumer demand for solar installations.
- Sunrun reported a net loss of $2.57 billion trailing twelve months, and its price-to-earnings ratio remains negative, reflecting ongoing unprofitability.
- The company faces margin pressure and revenue volatility due to the potential slowdown in new solar panel demand following the expiration of tax incentives.

NE

Considerations
- Noble’s financial performance remains exposed to cyclicality in the oil and gas sector, making it vulnerable to downturns in commodity prices and drilling activity.
