Sunrun, Inc. Q4 FY2024 earnings call

• The fourth quarter was exceptionally strong, with growth in contracted total value, positive cash generation for three consecutive quarters, and high storage attachment rates. - Sunrun adapted to market challenges, innovated through regulatory changes, built a robust supply chain, and responded to wildfires by adjusting batteries for backup power. - They have over 16 grid service programs active with over 20,000 customers participating, and their virtual power plants supported power grids with a combined instantaneous peak of nearly 80 megawatts. - Focus on high-quality growth, cost efficiency, and generating meaningful cash, with no need for equity funding.

In the fourth quarter, Sunrun saw strong performance. Storage attachment rates reached 62% of installations, an increase of 17 percentage points from the previous year. They installed 392 megawatt hours of storage in Q4, up 78% from the same quarter last year. Solar energy capacity installed was approximately 242 megawatts, within guidance. Customer additions were approximately 32,900, including approximately 30,700 subscriber additions. Subscription mix remained at 96% of deployments. Annual Recurring Revenue (ARR) stood at over $1.6 billion, up 23% compared to the same period last year. The net subscriber value was $19,177 in Q4, driven by higher battery attachment rates and ITC realization.

• Q1 2025 cash generation is guided to be $40 to $50 million, the fourth consecutive quarter of positive cash generation. - For full-year 2025, cash generation is expected to be in the range of $200 to $500 million, a revision from prior guidance due to slower ramp in domestic content ITC adders in the Affiliate Partner business, higher capital cost assumptions, and slightly lower volume expectations, partially offset by higher storage mix. - Storage attachment rates are expected to remain around 62% or slightly higher for the next few quarters. - Solar capacity installed in Q1 is expected to be in the range of 170 to 180 megawatts, and storage capacity installed is expected to be in the range of 265 to 275 megawatt hours.

• Potential policy changes that could impact operations. - Supply chain dynamics, including challenges with obtaining and qualifying domestic content hardware for Affiliate Partners. - Interest rate fluctuations and their impact on capital costs. - Irrational competitive behavior in the industry, such as uneconomic, cash-consuming activities by some new entrants.

Q: Could you square the $350 million safe harbor with the commentary that it covers about 12 months for solar and half a year for storage?

A: It's not a perfect optimization; the actual amount of purchase doesn't exactly align with a simple division, and the amount of aggregate value against which it applies is the fair market value of projects.

Q: How are you managing through potential lengthening of tax equity payment terms?

A: They're seeing a broadening of the tax equity buyer universe, including large corporates, and deal activity is quite active at the front end of the year.

Q: Can you elaborate on the slow ramp in domestic content for Affiliate Partners?

A: There are challenges with obtaining and qualifying domestic content hardware, and operationalizing processes to qualify can be challenging for some smaller partners.

Q: What's the status of labor pool and impact of immigration law?

A: Sunrun isn't seeing labor impact changes, has a good pipeline, and people are migrating to Sunrun as others slow down in the space.

Q: Talk about safe harbor cash deployment and continued deployment?

A: The $18 million spent in 4Q to secure $350 million is a run rate activity through the year, and future safe harbor activity could be incremental if planned.
