### Risk Assessment

- The company faces a shortage of qualified electricians in California due to new regulatory requirements, which could lead to project delays and higher labor costs. [EXECUTION] (NEUTRAL, Risk: MODERATE)
  > there are a limited number of C-10 certified electricians in the state and we are required to have each jobsite staffed with a Commercial Journeyperson or Residential Wireman... which may result in workforce shortages, operational delays, and increased costs.
- **[CATALYST] Solar And Clean Power Equipment US Policy Change** (NEGATIVE, Risk: HIGH): The risk has transitioned from a potential threat to an active regulatory headwind following the signing of the One Big Beautiful Bill Act (OBBB) on July 4, 2025. This law shortens the 48E credit for solar to 2027 and introduces 'Foreign Entity of Concern' (FEOC) restrictions that could deny credits for projects using certain foreign components. (3 intensifying, 1 high-severity)
  > The most notable recent tax legislation affecting our business is the OBBB that President Trump signed into law on July 4, 2025. The new law adjusts tax policies that Sunrun relies upon... it shortens the availability of the 48E credit for solar facilities to the end of 2027. The law also applies ne
- **[CATALYST] Solar And Clean Power Equipment Fed Rate Cycle** (NEUTRAL, Risk: MODERATE): Management confirms that historic interest rate increases starting in 2021 have resulted in a decrease in advance rates, reducing the proceeds received from certain Funds. This directly increases the amount of capital Sunrun must provide to finance deployments. (2 stable, 1 easing, 1 intensifying)
  > Higher interest rates reduce our advance rates, and correspond to a reduction in the proceeds we receive from certain investment funds. Because our financing structure is sensitive to volatility in interest rates, higher rates increase our cost of capital and decrease the amount of capital available
- **[METRIC] Solar And Clean Power Equipment Balance Sheet Resilience** (NEGATIVE, Risk: HIGH): Total net debt increased from $12.9 billion at year-end 2024 to $14.0 billion as of June 30, 2025. Interest expense also rose 19% year-over-year for the six-month period, reflecting the higher debt load and interest rate environment. (4 intensifying, 1 high-severity)
  > Total debt, net $ 14,795,345... We expect to incur substantially more debt in the future, which could intensify the risks to our business.
- **[PRINCIPLE] Solar And Clean Power Equipment Regulatory Position** (POSITIVE): The risk is currently in a state of flux; while the CSLB adopted a rule requiring C-10 licenses for certain work, a preliminary injunction is currently preventing its enforcement. However, the underlying shortage of C-10 certified electricians remains a constraint on growth in the state. (3 stable, 1 easing)
  > there is currently a preliminary injunction in the case and the CSLB is enjoined from taking any action to enforce or implement the regulation... If we are unable to hire, develop and retain sufficient certified electricians, our growth of solar and battery customers in California may be significant
- **[PRINCIPLE] Solar And Clean Power Equipment Revenue Quality** (NEGATIVE, Risk: HIGH): Concentration risk is extremely high; a single customer accounted for $683.7 million in revenue for the full year 2025, representing approximately 23% of total annual revenue. (1 intensifying, 1 stable, 1 high-severity)
  > Revenue from energy system sales from one customer represents approximately $174.6 million of the Company’s consolidated revenues for the three months ended March 31, 2026.
- **[PRINCIPLE] Solar And Clean Power Equipment Unit Economics** (NEUTRAL, Risk: MODERATE): The risk is stable but persistent. While a preliminary injunction currently prevents enforcement of the CSLB rule requiring C-10 licenses for all storage, the company is proactively training its workforce. (1 stable)
  > If the creditable basis is determined in these circumstances to be less than what we or our tax equity investment funds reported, we may owe our fund investors an amount equal to the amount by which the ITCs are reduced (including any interest and penalties)
- **[TREND] Solar And Clean Power Equipment Demand Cycle** (NEUTRAL): The risk remains high as originations in California continue to be below levels seen prior to the transition. Management notes that without increases in originations, new installations in their largest market (representing over 45% of customers) may continue to decline. (4 stable)
  > Since implementation of NBT, originations in California have continued to be below levels prior to the transition for us and across the residential solar industry. Without further increases in originations, our new installations in California may continue to decline compared to prior periods
- **[TREND] Solar And Clean Power Equipment Policy and Regulation** (NEGATIVE, Risk: HIGH): The risk is intensifying as the OBBB has now been signed into law (July 4, 2025), confirming the sunset of solar ITCs by end of 2027 and the expiration of the Section 25D credit for residential buyers as of Jan 1, 2026. (1 intensifying, 1 high-severity)
  > Since implementation of NBT, originations in California have continued to be below levels prior to the transition for us and across the residential solar industry. Without further increases in originations, our new installations in California may continue to decline compared to prior periods, which 
- **[TREND] Solar And Clean Power Equipment Supply Chain Reconfiguration** (NEGATIVE, Risk: MODERATE): The risk has intensified with the U.S. Commerce Department issuing final anti-dumping (AD) and countervailing duty (CVD) rates in April 2025 for imports from Vietnam, Malaysia, Thailand, and Cambodia, with rates reaching as high as 534.67%. Additionally, a new national security investigation into polysilicon was launched in July 2025. (4 intensifying)
  > The final determinations imposed a wide range of duty rates depending on the specific exporter... in some cases exceeding 3,400%. Even the individually determined rates applicable to major exporters from whom we or our suppliers may source such cells and modules may represent a material increase in 

### Scenario Analysis

- The AI-driven surge in electricity demand acts as a massive catalyst for Sunrun, transforming its residential solar assets into critical grid-balancing infrastructure. As hyperscalers consume more power, utilities are forced to pursue rate-base growth and transmission upgrades, which in turn increases retail electricity rates and makes Sunrun’s home-to-grid solutions more economically attractive to consumers. This creates a virtuous cycle where Sunrun evolves from a simple installer into a virtual power plant operator, though this growth is physically throttled by third-order grid interconnection bottlenecks and rising semiconductor costs for its hardware. (POSITIVE)
  > Interconnection limits or circuit-level caps imposed by utilities or regulators may significantly reduce our ability to sell electricity from our solar service offerings in certain markets or slow interconnections, harming our growth rate and customer satisfaction scores.
- Higher Treasury yields and credit spreads directly inflate Sunrun's cost of capital, reducing the 'advance rates' from tax equity and debt partners which are critical for funding new installations. This creates a second-order squeeze where the company must raise prices for homeowners, eroding the competitive advantage of solar versus utility power and slowing deployment volumes. Ultimately, this leads to a third-order structural shift where valuation dispersion widens between Sunrun and firms with less capital-intensive models, as investors demand a higher risk premium for Sunrun's 'refinancing wall' and long-duration cash flows. (NEGATIVE)
  > In particular, elevated interest rates, have resulted and may continue to result in a decrease in our advance rates, reducing the proceeds we receive from certain Funds. Because our financing structure is sensitive to volatility in interest rates, higher rates increase our cost of capital and may de
- Aggressive reciprocal tariffs and AD/CVD duties on Southeast Asian solar cells create an immediate inflationary shock to Sunrun's hardware procurement costs. This necessitates a second-order surge in working capital as the company aggressively 'safe harbors' inventory to lock in tax credits before OBBB-mandated 'Prohibited Foreign Entity' restrictions disqualify their current supply chain. Ultimately, this leads to a third-order valuation shift where Sunrun's long-term growth is no longer driven by consumer demand alone, but by its ability to navigate a shrinking window of policy visibility and higher domestic depreciation costs. (NEGATIVE)
  > In April 2025, the Administration implemented broad "reciprocal" tariffs, including a 10% baseline tariff on most imports. Following a 90-day pause to allow for bilateral negotiations, country-specific reciprocal tariffs took effect on August 7, 2025, with rates now ranging from 10% to 50% depending
