Sunrun Inc. (NASDAQ:RUN) Q3 2023 Earnings Call Transcript November 1, 2023
Operator: Good afternoon and welcome to Sunrun's Third Quarter 2023 Earnings Conference Call. All participants have been placed on mute. Please note that this call has been recorded and that 1 hour has been allocated for the call including the question-and-answer session. [Operator Instructions] I will now turn the call over to Patrick Jobin, Sunrun's Senior Vice President, Investor Relations. Please go ahead.
Patrick Jobin: Thank you, Sherry. Before we begin, please note that certain remarks we will make on this call constitute forward-looking statements. Although we believe these statements reflect our best judgment based on factors currently known to us, actual results may differ materially and adversely. Please refer to the company's filings with the SEC for more inclusive discussion of risks and other factors that may cause our actual results to differ from projections made in any forward-looking statements. Please also note these statements are being made as of today, and we disclaim any obligation to update or revise them. During today's call, we will also be discussing certain non-GAAP financial measures, which we believe can provide meaningful supplemental information for investors regarding the performance of our business and facilitate a meaningful evaluation of current period performance on a comparable basis with prior periods.
These non-GAAP financial measures should be considered as a supplement to and not as a substitute for, superior to, or in isolation from GAAP results. You will find additional disclosures regarding the non-GAAP financial measures discussed on today's call in our press release issued this afternoon and our filings with the SEC, each of which is posted on our website. On the call today are Mary Powell, Sunrun's CEO; Danny Abajian, Sunrun's CFO; Ed Fenster, Sunrun's Co-Executive and Co-Founder, is also on the call for the Q&A session. A presentation is available on Sunrun's investor relations website, along with supplemental materials. An audio replay of today's call, along with a copy of today's prepared remarks and transcript, including Q&A, will be posted to Sunrun's Investor Relations website shortly after the call.
We have allocated 60 minutes for today's call, including the Q&A session. And now, let me turn the call over to Mary.
Mary Powell: Thank you, Patrick. As you all know, this has been a volatile time across the solar industry with changes in important policies and rising interest rates, leading to difficult conditions in the sector. We are taking action and responding to this environment, which results in a lower growth outlook than we expected at the start of the year. We are also sharpening our focus on cash generation and continue to execute a customer-first, sustainable growth strategy that does not require equity funding. Here is what we are doing to respond to these tough conditions and improve our position. First, we are reshaping the business to be storage first. During the quarter, we rapidly accelerated storage adoption. And as a result, we are growing our lead as America's clean energy company, one that delivers a superior value proposition to customers and creates multiple value streams for our shareholders.
This is a significant national change management exercise and one that most competitors have not yet undertaken. Second, we have made thoughtful decisions on solar only volume. We are not chasing growth that has subpar economics. Therefore, we rejected opportunities for growth in Q4 that did not meet our return hurdles. Third, we intensified cost reductions through both process efficiency and a best-in-class artificial intelligence team. We have improved the customer experience and built a strong foundation to deliver increased value to customers over time. We installed 176 megawatt hours of storage capacity in Q3, growing 131% compared to the prior year and 68% from the prior quarter. We now have more than 1.1 gigawatt hours of storage capacity installed across the country.
Our storage offerings provide customers enhanced value and generate significantly higher margins for Sunrun, while providing a foundation for future monetization in the years to come. Our storage attachment rate was over 33% of our installations across the country in the third quarter, a significant increase from just 15% starting the year, and we expect this percentage will continue to climb. Our accelerating storage attachment rate presents a powerful opportunity to grow our clean energy generation business by providing at scale distributed power plant capabilities across America. We are driving enhanced customer value and forging valuable long-term relationships with our customers. In Q4, we launched our storage retrofit offering with strong early results.
In the quarters ahead, we expect to be installing meaningful volumes of storage in our existing customer base, as we have thousands of customers who have already expressed interest in the product. Being the chosen trusted provider to deliver this clean energy future is critical. As a testament to our customer first approach, our customer net promoter scores at the time of install increased nearly 7 percentage points compared to the prior year to approximately 70 points in Q3. We will launch an early renewal program in the coming quarter to provide customers with the opportunity to renew their subscriptions and lock in the benefits of our relationship. Our earliest customers have agreements scheduled to auto renew in about 2.5. This program also provides Sunrun with essential learning so we can scale effectively and take advantage of significant upside opportunities for cash generation in periods [indiscernible].
During the third quarter, we came in slightly below the midpoint of our guidance range on solar installation volume, deploying 258 megawatts of solar capacity as we increased our focus on higher value sales to storage plus solar customers. In the third quarter, we grew our customer base to over 900,000, representing 6.5 gigawatts of installed solar capacity. According to recent market research, we are not only the largest residential solar company in the United States, but in fact, we are second largest, even when you include utility scale solar. Overall, we are reiterating our commitment to drive meaningful cash generation. We aim to show the strength of our model with our customer first approach and differentiation as the leader in storage, executing against our disciplined growth and margin focus strategy.
We had $952 million in total cash at quarter end, and we have a durable funding model with no equity needs. Turning to Slide 5 to double click on our market leadership in California. The rate structure transition in California continues to present opportunities for Sunrun as we extend our lead with our pro-consumer solar plus storage offering. While demand has been slower to recover than we were expecting, we believe the opportunity remains significant, given increasing utility rates and frequent grid outages. While industry data is lagging, anecdotal information on market trends suggests we have or will be gaining share in California and expect this to accelerate in periods ahead, given our expertise in storage and subscription offerings. Sunrun storage attachment rates in our direct business are over 85% of sales in California and closer to 100% in the investor-owned utility service territories.
This is substantially higher than the rest of the industry, which we observe at less than 40% attachment rates. Importantly, we believe this provides customers with the best clean energy offering. As compared to solar-only installations in California, customers enjoy similar utility bill savings with backup storage and significantly more savings with our shift product. Our shift and backup storage products also provide stronger margins and future revenue opportunities for Sunrun as we network storage systems together to form distributed power plants, enhancing grid reliability and accelerating the transition to clean energy resources across the state. Turning to Slide 6, we continue to execute our margin-focused growth strategy. This quarter, we took action responding to higher interest rates with continued go-to-market optimizations, remaining disciplined in how we participate in the affiliate partner segment of the market, and focusing on our leadership in storage products.
These actions are fundamentally geared towards maximizing valuation creation for our shareholders. Because of these actions, we are adjusting our outlook for the full year. We are now guiding to 220 megawatts to 245 megawatts of solar capacity installations in Q4, which implies, full year growth of approximately 2% to 5% less than our prior guidance of 10% to 15% growth for the full year. Because of our strategic focus on storage products, both for new customers and existing customers, we are also introducing guidance of approximately 71% to 78% growth in storage capacity installed for 2023, which accelerates our cash generation trajectory. There are four key drivers of our revised outlook for solar capacity installations, as we highlight on the presentation slide.
First, we remain focused on providing the most pro-consumer offering in California. While the opportunity remains strong in California, the rebound is taking longer than we initially expected. Sales in Q3 recovered from Q2 following the transition to the new rate structure and have increased by almost 15% from the prior quarter, but are still approximately down a third compared to the prior year. We have great customer offers that are compelling in a market where grid outages are rampant and utility prices are increasing rapidly. We offer Shift, our simple non-backup product, and our more sophisticated backup storage product. We believe our Shift offering and backup storage product are the best options for customers and through our grid services programs deliver the most long-term value both for Sunrun and the communities where we operate.
Based on recent conversations with customers following the mid-year policy change in California, it is apparent that the new regulatory environment has caused confusion for many consumers about the true value proposition for solar-only systems. It is taking time for consumers to adapt to the new policy and to understand that storage products are now, by far, the best consumer product offerings in California. All of our storage product offerings continue to far outpace solar-only sales. As the long-term owner of assets, our interests are aligned to deliver the best customer value and to continue to invest in products that benefit our customers in the short and long term. The good news is that the value proposition of our Shift offering is strong, with typical year one savings of 10% to 30%.
Savings will only increase as utility rates increase. For instance, PG&E may get approval to increase rates by 13% in January. California is committed to electrification. Rates are likely to increase rapidly, and power shutoff events will continue to drive customers to seek more affordable and reliable clean energy sources. While California gets a lot of attention, it's important to note the benefits of running a diversified business which operates in many states. Installations outside of California have been robust, growing over 25% in Q3 compared to the prior year, while sales also continue to grow at double digits from the prior year. Second, the business transition we are undergoing to become a storage-first company requires retraining thousands of sales and installation personnel.
In time, the rapid increase in attachment rates for higher value storage offerings will deliver better net subscriber values and increased opportunities for good service programs. We are pleased with consumers' interest and uptake rates of our backup battery product, which has outsold our Shift product. This is favorable development, as systems with backup storage have higher margins. But these systems are more sophisticated to permit and install and therefore carry elongated cycle times between sales and installation. We are working through this accelerated change management as our operations teams learn to optimize processes and our sales teams refine how they communicate the more sophisticated and nuanced value proposition to customers. Third, we are disciplined in how we participate through affiliate channel partners.
We value companies that are focused on customer experience, that value our brand, platform, storage-first product suite, and sustainable pricing model. We value partners that share a long-term orientation and are embracing the transition to a storage plus solar future. We are seeing pockets of irrational behavior in the affiliate partner segment of the market with several financing-only participants scaling with pricing that we consider unattractive, which can influence short-term sales dealers' volume allocations. As a result, we have reduced our volume expectations through the affiliate partner channel in the near term. We've seen this behavior several times in the company's 16-year history and won't chase volumes at economics that we do not view as sustainable.
We believe our diversified market approach, which includes an integrated sales force and fulfillment capacity, provides insulation from these behaviors from financing-only firms and is a strategic benefit to Sunrun. Fourth, we are adjusting our geographic mix, sales channels and product offerings to adapt to the new interest rate environment. In the near term, these actions will maximize subscriber values and storage installations rather than solar megawatt volumes. This includes repositioning our geographic mix, such as exiting our direct business in Arizona earlier in the year and our recent growth in Texas. Reducing our solar megawatt annual growth target is not something we take lightly, but our focus on cash generation, having price discipline, and leading with a customer-centric mindset are prudent actions to take as we position the company to maximize long-term value as a storage first company.
These actions coupled with continued cost reductions will maximize long-term value creation and position us for meaningful cash generation. Taking a step back, amidst all the equity market volatility and near-term headwinds from higher interest rates and difficult market conditions in the sector. The long-term value drivers are intact, and Sunrun's position in the market has improved. We have been able to adapt to the higher interest rate environment as our pricing adjustments have coincided with utility rate inflation. While utility service reliability continues to deteriorate. We are at the beginning of a massive transition towards electrification, driving more electricity use at the home and can offer an affordable, reliable source of clean energy for millions of households.
I firmly believe that this challenging macroeconomic environment actually gives us opportunities to accelerate our long-term leadership position in the industry. I am confident we will capitalize on the market shifts to strengthen our position by remaining customer focused and long-term oriented. Speaking of customer focus and discipline, again this quarter I want to celebrate our teams across the country, in the field, and in our offices, who are helping accelerate this customer-led revolution in energy and practicing our strong culture of doing it safely and efficiently. This quarter, we are recognizing not one, but two top performing teams in the country. First, thank you to our top ranked install crew based on performance, safety, and customer experience from Tampa, Florida.
Second, our top ranked sales team based on growth, storage attachment rates, and customer experience from Fresno, California. Go Fresno and Tampa. I know you are listening and we appreciate you. Thank you for your contributions and leadership at Sunrun. With that, let me turn the call over to Danny for our financial updates.
Danny Abajian: Thank you Mary. Today I will cover our operating and financial performance in the quarter along with an update on our capital markets activities and outlook. Turning first to the results for the quarter on Slide 11. In the third quarter solar energy capacity installed was approximately 258 megawatts, a 1% increase from the same quarter last year, and within our guidance of 255 megawatts to 275 megawatts. Customer additions were approximately 33,800, including approximately 29,300 subscriber additions. Our subscription mix represented 89% of our deployments in the period, a meaningful increase from 83% last quarter and the highest level in two years. We have now installed over 76,000 solar and storage systems. We expect storage installations will grow substantially in the quarters ahead.
Sales of storage-attached systems have grown to over 40% nationally, which should continue to drive installed attachment rates meaningfully higher in future periods. Our backup storage offerings carry higher margins, typically by several thousand dollars per customer. During the quarter, we installed 176 megawatts of storage capacity, an increase of 131% from the same quarter last year, bringing total network storage capacity to over 1.1 gigawatt hours. We ended Q3 with approximately 903,000 customers and 754,000 subscribers, representing 6.5 gigawatts of network solar energy capacity, an increase of 20% year-over-year. Our subscribers generate significant recurring revenue with most under 20 year or 25 year contracts for the clean energy we provide.
At the end of Q3, our annual recurring revenue, or ARR, stood at over $1.2 billion, up 28% over the same period last year. We had an average contract life remaining of nearly 18 years. Turning to Slide 12. In Q3, subscriber value was approximately $47,100 and creation cost was approximately $36,000, delivering a net subscriber value of $11,030. Our Q3 subscriber value and net subscriber value now reflect the blended 31% investment tax credit, benefiting from approximately 13% of our subscriber mix that qualified for the energy communities ITC adder in the quarter. Total value generated, which is net subscriber value multiplied by the number of subscriber additions in the period was $323 million in the third quarter. Our present value-based metrics are presented using a 6% discount rate, but our financial underwriting already accounts for our current cost of capital, which is slightly below 8%.
As a reminder, to enable ease of comparison across periods, we generally do not update the discount rate frequently. Instead, we provide advance rate ranges that reflect current interest rates, enabling investors to calculate the obtainable net cash unit margins on our deployments. In addition, we provide a pro forma net subscriber value using the cost of capital observed for the quarter. At an 8% discount rate, net subscriber value was $4,715, and total value generated was $138 million. Turning to slide 13, we expect meaningful tailwinds to net subscriber value in future periods from the realization of additional ITC adders and from lower hardware prices we are seeing on our current procurement activities. While the energy communities ITC adder was operationalized in Q3, additional cash proceeds for systems that qualify for the low income and domestic content ITC adders are expected to be realized in the coming quarters.
The first low-income adder application window has opened, and code allocation awards are expected in late Q4 or early 2024. Guidance on what will qualify for the domestic content adder has been issued, but additional rulemaking processes are not expected until into 2024. Combined, these three adders represent up to $450 million or more in additional annual run rate cash proceeds. We are also seeing rapidly decreasing prices for key hardware components, which will start to flow through our reported costs over the next few quarters as we work through our higher cost inventory. On a like-for-like basis for a 7.5 kilowatt solar with backup battery system, by the end of next year, hardware costs are expected to decline by over 20% or nearly $3,000 per system from their second quarter peaks.
These beneficial trends may be obscured by an increasing mix of storage, which carries higher net margins, but will increase hardware and install costs and therefore impact creation costs. Turning to Slide 14. We have presented a pro forma net subscriber value to show the potential impacts to unit margins from the forthcoming ITC adders, if fully realized, along with the hardware cost tailwinds we expect in the coming quarters. Based on our mix of business in Q3, pro forma net subscriber value with these benefits was approximately $14,800 at a 6% discount rate and $8,500 at an 8% discount rate. Turning now to gross and net earning assets and our balance sheet on Slide 16. Gross earning assets were $13.3 billion at the end of the third quarter.
Gross earnings assets is the measure of cash flows we expect to receive from subscribers over time, net of operating and maintenance costs, distributions to tax equity partners and partnership flip structures, and distributions to project equity financing partners, all discounted at a 6% unlevered capital cost. Net earning assets were $4.6 billion at the end of the third quarter. Net earning assets is gross earning assets plus cash, less all debt. Net earning assets increased by $130 million this quarter. Net earning assets does not include inventory or other construction in progress assets or net derivative assets related to our interest rate swaps, all of which represent additional value. In addition, value creation upside we expect from future grid services opportunities and selling additional electrification products and services to our customer base, including our storage retrofit offering, are not reflected in these metrics.
We regularly enter into interest rate swaps to hedge capital costs on our newly installed customers. We are principally exposed to interest rate fluctuations between customer origination through shortly after installation when our systems are financed with project-level, non-recourse debt. Nearly all of this financing is insulated from near-term interest rate fluctuations, as our debt is either fixed-coupon, long-dated securities, or floating rate loans that have been hedged with interest rate swaps. As such, we do not adjust the discount rate used in net earning assets to match current capital costs for new installations. We ended the quarter with $952 million in total cash, an increase of $31 million compared to the prior quarter. We paid down our recourse working capital facility by $35 million as well.
Turning briefly to our capital markets activities and outlook on Slide 17. We currently realize project-level capital costs slightly below 8%, which is a weighted average of our non-recourse senior and subordinated debt interest rates. Our cost of capital indications are informed by both realized terms on our transactions, as well as observable market data, such as longer term treasury yields as a proxy for our base rate, and credit spreads across numerous comparable transactions completed in our sector. During the quarter, we successfully executed the largest ever residential solar securitization, raising $715 million dollars at a credit spread of 240 basis points, a 25 basis point improvement from our prior public securitization in May of this year.
Similar to prior transactions, we also raised an additional $253 million of subordinated non-recourse debt on the portfolio, bringing the cumulative advance rate to slightly above 84% of contracted subscriber value, exceeding the range we provided last quarter. We continue to maintain a robust project finance runway. As of today, closed transactions and executed term sheets provide us with expected tax equity capacity to fund over 235 megawatts of projects for subscribers beyond what was deployed through the third quarter. Sunrun also had $555 million in unused commitments available in its $1.8 billion non-recourse senior revolving warehouse loan at the end of the quarter to fund approximately 195 megawatts of projects for subscribers. This strong capital runway allows us to be selective in timing our capital markets activity.
We recently closed our first tax equity fund, which leverages the new tax credit transferability provisions from the Inflation Reduction Act, enabling us to more easily monetize tax credits with large corporate buyers. As more corporations become familiar with this new structure, we expect transferability funds to become a large part of our funding strategy. This will deepen and diversify our investor universe. Given the increased scale of our business, we plan to complete and upsize an extension of our non-recourse warehouse loan in the coming few months, as we have done several times before. We are also planning to extend our asset-based recourse working capital facility in 2024, ahead of its January 2025 maturity. As we have done several times before as well.
Our working capital facility syndicate includes a diversified group of 13 relationship lenders. Both loans are floating rate and neither is constrained by current borrowing-based limitations. Turning now to our outlook on Slide 19. We continue to believe that market is very under penetrated and can sustain robust growth throughout this decade. In this strong long-term demand backdrop, our priority is to generate cash by continuing to increase customer values through growing storage adoption and other higher value products and services and reducing costs by driving further efficiencies across the business. Given our storage-first company strategy, we are introducing guidance for storage capacity installed. Storage capacity installed is expected to be in a range of 180 megawatt to 200 megawatt hours in Q4.
This represents 108% to 131$ growth year-over-year. For the full year 2023, this range represents 71% to 78% growth. Solar energy capacity installed is expected to be in a range of 220 megawatt to 245 megawatts in Q4. This represents full year 2023 growth of approximately 2% to approximately 5% compared to our prior guidance range of 10% to 15% growth for the full year 2023. This reduction is due to the strategic decisions we have made to prioritize cash generation and lean further into our storage product offering, as well as other factors we have noted. We expect net subscriber value to be stable in Q4 compared to Q3. As we transition our mix to higher value storage systems, these more complex and time consuming installations result in more costs being realized for systems that have not yet met the definition of installed.
Our outlook does not include additional ITC adder benefits as we expect them to be realized in 2024, although this could occur sooner based on the pace of government processes. As is our practice, we will provide 2024 guidance on our fourth quarter earnings call. As Q1 2024 will have a significantly higher year-over-year storage attachment rate and Q1 of 2023 benefited from the anticipated phase-out of NEM2 in California, we expect year-over-year solar energy capacity installed will decline in that period. While weather is typically a headwind to rooftop solar installations in the winter season, we believe we can make significant progress as we ramp up our storage retrofit offering and also explore renewal opportunities. Turning to Slide 20.
We expect our disciplined and focused strategy will allow us to capitalize on our long-term opportunity with our current focus on cash generation in 2024. We are reiterating our range of $200 million to $500 million in recurring annual cash generation, which we expect to achieve by the fourth quarter of 2024. We generated cash in the third quarter and we expect cumulative cash generation to be positive through the end of 2024. Keep in mind, cash generation can be lumpy quarter-to-quarter based on project financing timing and inherent seasonality in our business. Our cash generation range is based on assumptions we have outlined on the bottom of Slide 20. We have responded to the higher interest rate environment with our go-to-market optimization actions.
We have noted the changes in our assumptions from last quarter on the slide, which include a higher backup storage attachment rate of greater than 40%, a slightly higher weighted average ITC mix of 35%, and a cost of capital range of 7.5% to 8%. With that, let me turn it back to Mary.
Mary Powell: Thanks, Danny. I am so appreciative of our hardworking team whose passion and ingenuity is helping Sunrun transition to a storage-first company to extend our differentiation, expand our margins, and deliver the best value to customers. Importantly, I believe our steadfast commitment to our discipline growth strategy will maximize the value we can create for the long run. Operator, we're ready for questions.
