Grid And Solar Services Will Shape Future Energy Landscape

Key Takeaways

• Expanding storage and grid services, cost efficiencies, and favorable financing are driving margin growth, recurring revenue, and improved long-term profitability.
  
• Rising demand for resilient home energy and supportive policy and tax strategies enhance customer growth and earnings visibility amid industry and market challenges.
  
• Looming tax credit expirations, policy uncertainty, intensifying cost pressures, and reliance on external capital threaten Sunrun's growth, margins, and long-term financial stability.

Catalysts

Designs, develops, installs, sells, owns, and maintains residential solar energy systems in the United States.

• Sunrun is rapidly scaling its storage and grid services offerings, enrolling a growing portion of its customer base (currently ~35% of 200,000 batteries, aiming for 10 GWh of dispatchable energy by 2029), enabling significant recurring revenue growth and expanded margin opportunities as demand for grid support rises. This will positively impact long-term revenue and net margins.
  
• Declining equipment and installation costs-achieved through technological advancement, process optimization, and economies of scale-are driving consistent reductions in customer acquisition and creation costs. These efficiencies are translating into record high net subscriber value and improved operating margins, supporting future earnings growth.
  
• The combination of rising utility rates and increased grid instability is intensifying customer demand for resilient home energy solutions; Sunrun's leadership in solar+storage and VPP programs positions it to capture higher adoption rates and revenue per customer, particularly as electrification trends increase household energy needs.
  
• Sunrun's proactive strategy to "safe harbor" equipment and lock in solar investment tax credits through 2029 and potentially beyond, alongside ongoing policy support for storage through 2033, provides earnings visibility and refinancing capacity, supporting near
• and mid-term margin stability even as some incentives phase out.
  
• Sunrun's ability to maintain and expand access to attractively priced financing (demonstrated by strong tax equity and asset-backed securitization activity) in a tightening capital market environment supports cash generation and de-leveraging, mitigating financial risks and promoting sustainable long-term profitability.

Sunrun Future Earnings and Revenue Growth

Assumptions

• Analysts are assuming Sunrun's revenue will grow by 10.4% annually over the next 3 years.
• Analysts assume that profit margins will increase from -120.6% today to 16.2% in 3 years time.
• Analysts expect earnings to reach $465.4 million (and earnings per share of $1.85) by about September 2028, up from $-2.6 billion today. However, there is a considerable amount of disagreement amongst the analysts with the most bullish expecting $1.1 billion in earnings, and the most bearish expecting $-382.1 million.
• In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 11.7x on those 2028 earnings, up from -1.5x today. This future PE is lower than the current PE for the US Electrical industry at 29.6x.
• Analysts expect the number of shares outstanding to grow by 2.85% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 12.32%, as per the Simply Wall St company report.

Sunrun Future Earnings Per Share Growth

Risks

• Sunrun faces significant long-term revenue and demand risk due to the expiration of the 25D (homeowner) and eventually the 48E (commercial) solar Investment Tax Credits, with management estimating the overall residential solar market could contract by 25% when the 25D credit sunsets and only some of that volume is expected to migrate to Sunrun; this reduced addressable market could lead to slowed growth in customer additions and top-line revenue post-2025/2028.
  
• Prolonged safe harbor equipment purchases, intended to maximize solar ITC benefits before expiration, will tie up substantial working capital and potentially leave Sunrun exposed to inventory and equipment degradation risks, particularly given shorter visibility into residential solar demand-potentially impacting net margins and cash generation if demand underperforms forecasts or if there is unfavorable retroactive regulatory change.
  
• There is considerable uncertainty and vulnerability around regulatory and policy changes, including the possibility (even if considered low-probability) of retroactive application of stricter tax credit guidance; sudden or adverse policy shifts at the federal or state level could significantly compress margins and earnings by removing or reducing key incentives faster than Sunrun can offset with cost reductions or new products.
  
• Customer acquisition cost (CAC) reductions and cost efficiency gains, while highlighted as ongoing opportunities, face structural limits as attaining future cost cuts without lowering sales volume may become increasingly difficult; as more market growth depends on high-quality leads and innovation rather than broad expansion, elevated CAC and servicing costs threaten long-term operating margins and profitability.
  
• The company's capital-intensive, highly-leveraged business model and reliance on continued access to attractively priced capital via tax equity, debt markets, and securitizations leaves Sunrun exposed to potential tightening in credit markets, rising interest rates, and shifting investor attitudes toward residential solar-posing long-term risks to cash generation, debt service, and ultimately net earnings if external financing becomes more costly or less available.

Valuation

• The analysts have a consensus price target of $15.289 for Sunrun based on their expectations of its future earnings growth, profit margins and other risk factors. However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of $25.0, and the most bearish reporting a price target of just $10.0.
• In order for you to agree with the analyst's consensus, you'd need to believe that by 2028, revenues will be $2.9 billion, earnings will come to $465.4 million, and it would be trading on a PE ratio of 11.7x, assuming you use a discount rate of 12.3%.
• Given the current share price of $16.48, the analyst price target of $15.29 is 7.8% lower. The relatively low difference between the current share price and the analyst consensus price target indicates that they believe on average, the company is fairly priced.
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
