Our actual results and timing of these events may differ materially from those anticipated in these forward-looking statements as a result of many factors, including but not limited to those discussed under "*Risk Factors*" and elsewhere in this Annual Report on Form 10-K. Moreover, we operate in a very competitive and rapidly changing environment and new risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this Annual Report on Form 10-K may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements. We undertake no obligation to update publicly any forward-looking statements for any reason after the date of this Annual Report on Form 10-K to conform these statements to actual results or to changes in our expectations, except as required by law.

**Summary of Risk Factors**

The risk factors detailed in Item 1A entitled "*Risk Factors*" in this Annual Report on Form 10-K, are the risks we believe are material to our investors and a reader should carefully consider them. The following is a summary listing certain of the risk factors detailed in Item 1A:

**Risks Related to Our Business**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Historically, we have incurred operating and net losses and we may be unable to achieve or sustain profitability in the future.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our growth strategy depends on the continued origination of solar service agreements by us and our dealers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our growth is dependent on our dealer network and our failure to retain or replace existing dealers or to grow our dealer network could adversely impact our business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We do not directly control certain costs related to our business, which could put us at a disadvantage relative to companies who have a vertically integrated business model.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may be unsuccessful in introducing new service and product offerings, including our distributed energy storage services and energy storage management systems.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our business is concentrated in certain markets, putting us at risk of region-specific disruptions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Certain of our solar energy systems are located in, and we conduct business in, Puerto Rico. Weakness in the fiscal health of the government and the Puerto Rico Electric Power Authority ("PREPA"), the damage caused by hurricanes, a series of earthquakes that affected the island in December 2019 and early 2020 and potential tax increases that may increase our cost of conducting business in Puerto Rico, create uncertainty that may adversely impact us. In addition, we are subject to administrative proceedings instituted by the Puerto Rico Energy Bureau ("PREB").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The ongoing COVID-19 pandemic and future pandemics could adversely affect our business, financial condition and results of operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our operating results and our ability to grow may fluctuate from quarter to quarter and year to year, which could make our future performance difficult to predict and could cause our operating results for a particular period to fall below expectations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If our allowance for credit losses is not enough to cover actual credit losses from our customer notes receivable portfolio, our results of operations and financial condition could be negatively affected.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Certain of our key operational metrics, including estimated gross contracted customer value, are based on various assumptions and estimates we make that cover an extended period of time. Actual experience may vary materially from these estimates and assumptions and therefore undue reliance should not be placed on these metrics.

**Risks Related to the Solar Industry**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If sufficient additional demand for solar energy systems does not develop or takes longer to develop than we anticipate, our origination of solar service agreements may decrease.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A material reduction in the retail price of electricity charged by electric utilities or other retail electricity providers would harm our business, financial condition and results of operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our business has benefited from the declining cost of solar energy system and energy storage system components and may be harmed to the extent the cost of such components stabilize or increase in the future.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We and our dealers depend on a limited number of suppliers of solar energy system components and technologies to adequately meet demand for our solar energy systems. Due to the limited number of suppliers in our industry, the acquisition of any of these suppliers by a competitor or any shortage, delay, price change, imposition of tariffs or duties or other limitation in our or our dealers' ability to obtain components or technologies we use could result in sales and installation delays, cancelations and loss of customers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Increases in the cost or reduction in supply of solar energy system and energy storage system components due to tariffs or trade restrictions imposed by the U.S. government could have an adverse effect on our business, financial condition and results of operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Terrorist or cyberattacks against centralized utilities could adversely affect our business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We face competition from centralized electric utilities, retail electric providers, independent power producers and renewable energy companies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Developments in technology or improvements in distributed solar energy generation and related technologies or components may materially adversely affect demand for our offerings.

**Risks Related to our Financing Activities**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We need to obtain substantial additional financing arrangements to provide working capital and growth capital. If financing is not available to us on acceptable terms when needed, our ability to continue to grow our business would be materially adversely impacted.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Servicing our existing debt requires a significant amount of cash. We may not have sufficient cash flow from our business to

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

timely pay our interest and principal obligations and may be forced to take other actions to satisfy our payment obligations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Volatility and continued increases in interest rates would raise our cost of capital and may adversely impact our business.

**Risks Related to Regulations**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We are not currently regulated as an electric public utility under applicable law but may be subject to regulation as an electric utility in the future.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Electric utility policies and regulations, including those affecting electric rates, may present regulatory and economic barriers to the purchase and use of solar energy systems that may significantly reduce demand for electricity from our solar energy systems and adversely impact our ability to originate new solar service agreements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We rely on net metering and related policies to offer competitive pricing to our customers in most of our current markets and changes to net metering policies may significantly reduce demand for electricity from solar energy systems.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our business currently depends in part on the availability of rebates, tax credits and other financial incentives. The expiration, elimination or reduction of these rebates, credits or incentives or our ability to monetize them could adversely impact our business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our business depends in part on the regulatory treatment of third-party owned solar energy systems.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Technical and regulatory limitations regarding the interconnection of solar energy systems to the electrical grid may significantly reduce our ability to sell electricity from our solar energy systems in certain markets or delay interconnections and customer in-service dates, harming our growth rate and customer satisfaction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our business is subject to complex and evolving privacy and data protection laws. Many of these laws and regulations are subject to change and uncertain interpretation and could result in claims, increased cost of operations or otherwise harm our business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our business is subject to consumer protection laws. Such laws and regulatory enforcement policies and priorities are subject to change that may negatively impact our business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The highly regulated environment in which our capital providers operate could have an adverse effect on our business.

**Risks Related to Taxation**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our ability to use net operating loss carryforwards ("NOLs") and tax credit carryforwards to offset future income taxes is subject to limitation and the amount of such carryforwards may be subject to challenge or reduction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Changes in tax law could adversely affect our business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If the IRS or the U.S. Treasury Department makes a determination that the fair market value of our solar energy systems is materially lower than what we have reported in our tax equity vehicles' tax returns, we may have to pay significant amounts to our tax equity vehicles, our tax equity investors and/or the U.S. government. Such determinations could have a material adverse effect on our business and financial condition.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If our solar energy systems either cease to be qualifying property or undergo certain changes in ownership within five years of the applicable placed in service date, we may have to pay significant amounts to our tax equity vehicles, our tax equity investors and/or the U.S. government. Such recapture could have a material adverse effect on our business and financial condition.

**Risks Related to Our Common Stock**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We do not intend to pay, and our credit facilities currently prohibit us from paying, cash dividends on our common stock and, consequently, your only opportunity to achieve a return on your investment is if the price of our common stock appreciates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Ownership of our common stock by current stockholders is expected to remain significant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The price of our common stock is volatile and may decline in value.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provisions of our charter documents and Delaware law may inhibit a takeover, which could limit the price investors might be willing to pay in the future for our common stock.

**General Risk Factors**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We are exposed to the credit risk of our customers and payment delinquencies on our accounts receivable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our actual financial results may differ materially from any guidance we may publish from time to time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If we are unable to make acquisitions on economically acceptable terms, our future growth could be limited, and any acquisitions we may make may reduce, rather than increase, our cash flows.

**PART I - FINANCIAL INFORMATION**

**Item 1. Business.**

**Mission**

To power energy independence.

**Overview**

We are a leading Energy as a Service ("EaaS") provider, serving over 279,000 customers in more than 45 United States ("U.S.") states and territories. Our goal is to be the source of clean, affordable and reliable energy with a simple mission: to power energy independence so home and business owners have the freedom to live life uninterrupted. We were founded to deliver customers a better energy service at a better price; and, through our energy service offerings, we are disrupting the traditional energy landscape and the way the 21st century customer generates and consumes electricity. Additionally, we believe the renewable energy market in which we operate, and investment in climate solutions more broadly, will continue to grow as the impact of climate change increases. While our core business model seeks to help accelerate a global transition to renewable energy, there are inherent climate-related risks to our business operations including, but not limited to, those discussed under "*Risk Factors*" and elsewhere in this Annual Report on Form 10-K.

We have a differentiated dealer model in which we partner with local dealers who originate, design and install our customers' solar energy systems, energy storage systems and related products and services on our behalf. Our focus on our dealer model enables us to leverage our dealers' specialized knowledge, connections and experience in local markets to drive customer origination while providing our dealers with access to high quality products at competitive prices, as well as technical oversight and expertise. We believe this structure provides operational flexibility, reduces exposure to labor shortages and lowers fixed costs relative to our peers, furthering our competitive advantage.

We offer customers products to power their homes and businesses with affordable solar energy and related products and services. We are able to offer savings compared to utility-based retail rates with little to no up-front expense to the customer in conjunction with solar and solar plus energy storage, and, in the case of the latter, are able to also provide energy resiliency. Our solar service agreements typically take the form of a lease, power purchase agreement ("PPA"), loan or cash purchase; however, we also offer service plans for systems we did not originate. We make it possible in some states for a customer to obtain a new roof and other ancillary products as part of their solar loan. We also allow customers originated through our homebuilder channel the option of purchasing the system when the customer closes on the purchase of a new home. The initial term of our solar service agreements is typically between 10 and 25 years. Service is an integral part of our agreements and includes operations and maintenance, monitoring, repairs and replacements, equipment upgrades, on-site power optimization for the customer (for both supply and demand), the ability to efficiently switch power sources among the solar panel, grid and energy storage system, as appropriate, and diagnostics. During the life of the contract, we have the opportunity to integrate related and evolving servicing and monitoring technologies to upgrade the flexibility and reduce the cost of our customers' energy supply.

For our leases and PPAs, we also currently receive tax benefits and other incentives from federal, state and local governments, a portion of which we finance through tax equity, non-recourse debt structures and hedging arrangements in order to fund our upfront costs, overhead and growth investments. We have an established track record of attracting capital from diverse sources.

In addition to providing ongoing service as a standard component of our solar service agreements, we also offer ongoing energy services to customers who purchased their solar energy system through third parties. Under these arrangements, we agree to provide monitoring, maintenance and repair services to these customers for the life of the service contract they sign with us. In addition, we offer one-time repair services to customers who purchased their solar energy systems through third parties. We also offer complimentary products to our agreements as well as non-solar financing. Specifically, our offerings include a non-solar loan program enabling customers to finance the purchase of products independent of a solar energy system or energy storage system. We believe the quality and scope of our comprehensive energy service offerings, whether to customers that obtained their solar energy system through us or through another party, is a key differentiator between us and our competitors.

In April 2021, we acquired SunStreet Energy Group, LLC, a Delaware limited liability company ("SunStreet"), Lennar Corporation's ("Lennar") residential solar platform that focuses primarily on solar energy systems and energy storage systems for homebuilders. In connection with that acquisition, we entered into an agreement pursuant to which we would be the

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

exclusive solar and storage provider for Lennar's new home communities with solar across the U.S. for a period of four years. We believe the acquisition provides a new strategic path to further scale our solar business, reduces customer acquisition costs, provides a multi-year supply of sites through the development of new solar communities and allows us to pursue the development of clean and resilient microgrids across the U.S.

We also enter into leases with third-party owners of pools of solar energy systems to receive such third party's interest in those systems. In connection therewith, we assume the related customer PPA and lease obligations, entitling us to future customer cash flows as well as certain credits, rebates and incentives (including solar renewable energy certificates ("SRECs")) under those agreements, in exchange for a lease payment, whether upfront or over time, to the third-party owner, which may be made in the form of cash or shares of our common stock. We believe such arrangements enhance our long-term contracted cash flows and are complementary to our overall business model.

We commenced operations in January 2013 and began providing solar energy services under our first solar energy system in April 2013. Since then, our brand, innovation and focused execution have driven significant, rapid growth in our market share and in the number of customers on our platform. We operate one of the largest residential fleets of solar energy systems in the U.S., comprising more than 1,627 megawatts of generation capacity and serving over 279,000 customers as of December 31, 2022. For a discussion of how we define number of customers, see "*Management's Discussion and Analysis of Financial Condition and Results of Operations*—*Key Financial and Operational Metrics"*. The following chart illustrates the growth in our number of customers from December 31, 2018 through December 31, 2022.

**Our Dealer Network Model**

While many of our competitors maintain a large, geographically diverse base of employees in local markets, including a direct sales force comprised of home improvement installers, we limit the cost associated with that structure by primarily utilizing a network of local, independent dealers to market, sell and install solar energy systems, energy storage systems, home generators and certain other products and services on our behalf. Our dealers typically reside and work within the markets they serve and provide a localized, customer-focused marketing, installation and servicing process. These dealers are often leading local solar installation companies, electrical services companies or companies that serve customers who are actively searching for solar power, backup power, complimentary services or who were referred by existing customers. When entering new markets, our dealer model immediately provides scale by enabling us to develop relationships with existing local businesses and avoiding the delay and expense required to establish new sales and installation offices. Similarly, because we do not typically maintain local offices, we can quickly refocus our origination efforts and capital deployment strategy to different markets in response to changing dynamics and regulatory developments. Furthermore, because of the low marginal cost to maintain relationships with individual dealers in currently unfavorable markets, we can maintain a strategic presence in anticipation of future developments that may make the economics of distributed solar energy in those markets more attractive.

Our dealers realize value in partnering with us for a variety of reasons. Although each of our dealer relationships is unique, we believe our dealers choose to work with us because:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we do not compete with our dealers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we receive preferred equipment pricing as a result of our strong supplier relationships;

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we offer a wide variety of product structures;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we provide easy-to-use software to dealers to assist with the installation process and to price potential solar energy systems and energy storage systems;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• dealers can leverage our brand and reputation for customer service to support their businesses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we provide comprehensive training to dealers; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we are a stable counterparty our dealers can trust to make payments on time.

***Origination, Installation, Monitoring and Servicing Processes***

Through our dealer network model, we provide a streamlined approach for the origination of solar service agreements and the installation of solar energy systems and energy storage systems. The principal elements of our origination, installation, monitoring and servicing processes are described below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Customer Origination and Consultation.* Our dealers serve as a local, direct-to-home sales force providing in-person and virtual consultations to source potential customers in each geographic market where we operate. Our dealers reach potential customers through various means, including online, telemarketing, in-store sales, cross-marketing with complementary products and door-to-door canvasing. Using our technology platform and proprietary pricing tool, the dealer and the customer select one of our standard-form solar service agreements for the relevant market. Before proceeding to the design phase, we confirm that every customer understands the terms of their contract with us as well as the expected benefits of the system.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Installation, Commissioning, Quality Assurance and Interconnection*. The installation and commissioning phase requires the dealer to obtain all necessary permits for installation and complete our commissioning process for the solar energy system and energy storage system (if applicable), which entails submitting supporting documentation and photographs illustrating the installation of the solar energy system and energy storage system (if applicable) to our quality assurance team for review. Following completion of these steps and our approval of these materials, the dealer submits required paperwork to the applicable electric distribution utility to obtain permission to operate the equipment, schedule required regulatory inspections and arrange for interconnection of the solar energy system to the electrical grid. In some markets where either permission is not required and/or interconnection is not feasible or practical, we may place the system in service without interconnecting to the electrical grid and thereby place the system in service without seeking permission to operate from the applicable electric distribution utility.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Customer Billing Dates*. How soon we will begin billing the customer after the solar energy system has been placed in service will vary by product offering. Lease agreements will begin billing on the first cycle date after the solar energy system has been placed in service, generally within 30 days. PPAs will begin billing on the first cycle date in the next calendar month after the solar energy system has been placed in service, generally between 15 and 60 days after the solar energy system has been placed in service. Loan agreements require the solar energy system must be in service at least 30 days or, where permitted by law, installed for 60 days prior to the date when billing can begin. As a result, billing on loan agreements generally begins the first cycle date in the next calendar month after the solar energy system has been installed or placed in service.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Monitoring and Servicing*. Our monitoring systems utilize cellular or internet connections that allow us to confirm the continuing operation of the solar energy system and energy storage system (if applicable) and with that information, solve maintenance issues through our dealers, third-party service providers or our own personnel. We also collect performance data to improve our pricing, generation estimates and services for our customers.

***Our Relationships With Our Dealers***

We carefully recruit our dealers, who must meet and maintain our standards to be an approved dealer. Qualifications to be a dealer include: experience in the solar industry (or success in complementary industries such as home security, heating, ventilation and air-conditioning, electrical services, and satellite television), experienced and appropriately certified employees (including multiple installation teams) and possession of applicable licenses. We also perform a review of the prospective dealer's financial condition as part of our recruitment process, a background check on the principal owners of the organization and a careful review of the dealer's online and local reputation. Upon engagement, the dealer enters into a standard dealer agreement with us, which may be amended from time to time, that sets ongoing standards for operations and payment obligations based on different milestones for each project. We provide training, field support and continuing education to help our dealers operate efficiently. This includes training related to our processes, standards and services platform, sales training and compliance education regarding applicable rules and regulations. We actively review our dealers' performance and compliance with our requirements to determine whether to terminate our relationship with any dealer that is unable to meet our performance standards.

We devote significant resources to maintaining and expanding our relationships with existing dealers. Although most of our dealer agreements allow the dealer to sell services and products from our competitors, we believe dealers find our proprietary technology and operations platform, established supply chain group, commitment to training, quality of service, corporate balance sheet and prompt payment to be incentives to prioritize selling our services. Furthermore, many of our dealers may be hesitant to work with our competitors that have developed internal sales and installation personnel that may compete with certain aspects of the dealer's business. Taken as a whole, we believe these considerations promote long-lasting relationships with our dealers.

For the years ended December 31, 2022 and 2021, Trinity Solar, Inc. ("Trinity") accounted for approximately 19% and 15% of our net originations, respectively. In October 2022, we amended our agreement with Trinity pursuant to which Trinity has agreed to perform services or work exclusively for us for sixty-six months to March 31, 2028 (the "Exclusivity Period"), with certain exceptions, including (a) the sale of solar energy systems, energy storage systems, generators or electric vehicle chargers ("Agreed Products") to individuals on a "cash" basis that do not involve private financing marketed by Trinity, (b) the sale of Agreed Products to individuals who, based on their credit score(s) and other relevant attributes, Trinity reasonably determines do not qualify under our credit and underwriting standards then in effect and (c) the sale of Agreed Products pursuant to customer agreements executed prior to the date of the amendment to the dealer agreement. The amendment permits immaterial failures to comply with the foregoing exclusivity obligations provided that such failures are inadvertent, made without knowledge and/or intent of Trinity's management, and provided that such failures do not account for more than 2% of Trinity's installations in any single year during the Exclusivity Period. In addition, Trinity may install Agreed Products for our competitors in instances in which Trinity has available installation capacity, and, following notice to us that such capacity is available, we can either indicate that we do not intend to use such installation capacity or fail to timely respond to the notice. Trinity's exclusivity obligations do not apply to new roofs or roof replacements, or to Agreed Products sold for commercial applications. Under this arrangement, we have agreed to provide bonuses to Trinity in the amount of $12.9 million for the six month period ending March 31, 2023 and $30.0 million for each of the five subsequent year-long periods. The bonus payments are subject to a true-up payable by (a) us if Trinity exceeds 120% of its annual target or (b) Trinity if it does not meet at least 80% of its annual target, though we will not owe Trinity a true-up for its first year performance under any circumstances. The annual installation targets increase by approximately 2.3% to 7.1% each year. Unlike most of our dealer agreements, the arrangement with Trinity does not permit the parties to terminate for convenience and only permits termination in specified circumstances including material breach (subject to applicable cure periods), prolonged force majeure events, a change of control, certain insolvency events or mutual agreement. For purposes of the Trinity agreement, "change of control" means (a) the sale of all or substantially all of the assets of a party or (b) any merger, acquisition or other transaction or series of transactions that results in any "person" becoming the "beneficial owner" (as those terms are used in Section 13(d), Rule 13d-3 and Rule 13d-5 of the Exchange Act of more than fifty percent of the voting securities of a party (subject to certain exclusions). Additionally, the arrangement provides for a liquidated damages payment of the greater of $50.0 million or the sum of all remaining annual bonus payments at the time of the termination by the applicable party in the event of termination for material breach, certain insolvency events of or wrongful termination by the other party.

We have similar contractual arrangements with several other key dealers and third parties. For certain other dealers and third parties, substantially all of the solar service agreements originated by such dealers and third parties are Sunnova agreements, although they are under no exclusivity arrangement. During the year ended December 31, 2022, Lennar and Windmar PV Energy, Inc ("Windmar Energy") accounted for 15% and 13%, respectively, of our net originations. During the year ended December 31, 2021, Lennar and Windmar Energy accounted for 20% and 11%, respectively, of our net originations. No dealer or third party other than Trinity, Lennar and Windmar Energy accounted for more than 10% of our net originations during 2022 or 2021.

**Direct Sales**

We have established an inside sales team to market and sell a limited set of products and services in circumstances where there is no existing relationship between a potential customer and our dealers to market on our behalf. This sales team is primarily focused on selling stand-alone solutions, such as Sunnova Protect Services, Sunnova +SunSafe and financing for electric vehicle chargers, generators and other supplements as requested by consumers. In most cases, these services will be directed to a third-party installer in our dealer network, as required, for the installation of any equipment.

**Commercial Sector**

We have established a division to serve commercial, industrial, agricultural, not-for-profit and public sector customers. This division is primarily focused on offering stand-alone solutions, such as solar energy systems, energy storage systems and electric vehicle chargers as requested by customers, through a lease agreement, loan agreement or cash purchase.

**Grid Services**

We have developed relationships with various independent system operators, utilities, community choice aggregators and others, seeking to provide them with specialized grid services so these grid participants can more efficiently conduct their operations. Examples of these services include demand response as well as grid capacity and voltage management. These grid programs can make use of the solar energy systems, energy storage systems and other technologies installed in customer homes and businesses and managed by us via a centralized platform and internally developed software. By providing grid services, we seek to earn additional revenue, improve grid resiliency and operations where our customers are located, and lower the cost of power to our customers.

**California Microgrid Application**

In September 2022, we applied to the California Public Utilities Commission ("CPUC") for a certificate to own and operate community microgrids in California. This effort, if successful, would allow us to enter into the regulated utility sector of electric service. Our application focuses on microgrids for new communities where the installation of the microgrid can be performed together with the construction of the new community. In February 2023, an administrative law judge issued a proposed decision to deny our application, which will be considered by the CPUC in its decision regarding our application. If the application is granted, we will pursue the construction of behind-the-meter solar energy systems and energy storage systems that are integrated with community-scale front-of-the-meter solar energy systems, energy storage systems, backup generation systems and distribution and microgrid controls, which together will be used to serve the electric requirements for the entire community. The microgrids are expected to be connected to the larger grid so we can provide supplemental electricity to our customers from the wholesale market and sell excess electricity and related products to the same market.

**Software Platforms**

We have developed cloud-based technology platforms for origination, installation, administration, orchestration and servicing of our energy solutions. Our proprietary dealer, customer and energy management software supports customers, dealers and internal users in the sale, installation and management of our products and services. The platforms leverage cloud-based infrastructure and software capabilities using multiple third-party providers, including Salesforce, Amazon Web Services, Heroku and FinancialForce. The platforms are compatible with multiple end-user device types, including smartphone, tablet and desktop/laptop interfaces.

Our key software systems include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***Sunnova Catalyst***<sup>TM</sup> ***Dealer Platform***: Sunnova Catalyst enables dealers to manage leads, design systems, generate quotes and create contracts, plan sets and commissioning packages through a combination of web, tablet and mobile device interfaces. As part of the quoting feature set, customer pricing is delivered by a combination of cloud-based technologies including Genability, PV Watts (a service of the National Renewable Energy Laboratory) and proprietary applications running on Amazon Web Services and Heroku. We enable dealers to generate solar service agreement and proposal documents on demand for presentation to prospective customers. Each completed quote is transferred into Salesforce for solar service agreement generation, customer access and reporting. Sunnova Catalyst also includes features to streamline the approval process for the design and installation of solar energy systems, track install progress and establish a standard process for ongoing service and warranty management.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***Sunnova App and Portal***: Sunnova App and Portal are our mobile and web experiences for customers. The mobile and web apps enable customers to view their solar energy systems' production history, view energy storage system data, pay their bills, manage their account and contact information, make referrals and contact our customer service team. Sunnova App is available for both Android and iOS.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***Sunnova Sentient***<sup>TM</sup>***:*** Sunnova Sentient is our proprietary platform for energy awareness, intelligence and control. Sunnova Sentient powers Sunnova Adaptive solutions for homes, businesses and communities. We are incorporating Sunnova Sentient into our dealer and customer platforms to recommend customer-specific energy solutions and optimize customer products and services.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***Salesforce***: Salesforce is our central repository and system of record for all contracts, process documentation, customer account information, maintenance information and payment tracking for the life of the solar service agreement. This single system allows for integrated and comprehensive reporting for the entire life cycle of the customer, from quote to end of the solar service agreement term. Many of our other systems interact with the Salesforce platform.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***FinancialForce***: FinancialForce is a cloud-based accounting system built on the Salesforce platform.

**Cybersecurity**

In an effort to reduce the likelihood and severity of cyber incidents, we maintain a cybersecurity program designed to monitor, protect and preserve the confidentiality, integrity and availability of data and systems, overseen by our board of directors (our "Board") and guided by external specialists. The program establishes security standards and guidelines for our technological resources and includes training for employees, contractors and third parties and testing by third party experts of our cybersecurity capabilities. As part of this program, we also maintain an incident response plan and retain specialist service providers under contract. Our current security posture and compliance efforts are intended to address evolving and changing cyber threats.

We focus on growing a geographically diverse customer base with a strong credit profile. We perceive our recurring customer payments as high-quality assets given the broad and relatively inelastic demand for electricity and because our customers typically have high credit scores. As of December 31, 2022, our customers had, at the time of signing the solar service agreement, an average FICO<sup>®</sup> score of 739. The purpose of our stringent credit approval policy is to ensure reliability of collecting payment over the duration of the solar service agreements. As of December 31, 2022, approximately 0.9% of our customers were in default (over 120 days past due) under their solar service agreements.

Our solar service agreements typically have an initial term ranging from 10 to 25 years. Our lease and PPA agreements typically include an opportunity for customers to renew for up to an additional 10 years via two five-year or one 10-year renewal options. The customer is obligated to make monthly payments to us, and we operate and maintain the solar energy system and energy storage system, if applicable, in good condition throughout the duration of the agreement. Under our lease agreements and PPAs, the customer's monthly payment or price per kilowatt hour ("kWh") is set based on a calculation that takes into account the life of the equipment and/or expected solar energy generation. The customer has an option of choosing a flat rate without an escalator or a lower initial rate with an escalator. As of December 31, 2022, approximately 44% of our lease agreements and PPAs contained a price escalator, ranging from 0.9% to 3.0% annually.

Our solar service agreements are designed to offer the customer energy cost savings and bill stability relative to centralized utility prices, often resulting in an immediate reduction in the customer's overall utility bill, with little or no upfront costs. We provide our services through long-term solar service agreements in the following formats:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Lease Agreements*. Under the Easy Plan equipment lease, the customer leases a solar energy system from us at a fixed monthly rate that is typically subject to annual escalation. Under the LeasePlus New Home Solar Plan, the customer leases a solar energy system from us at a fixed monthly rate that is not subject to escalation throughout the term of the lease. Under the Prepaid LeasePlus New Home Solar Plan, the lease is prepaid upfront for the term of the lease. The Solar Benefits Agreement is offered to customers in certain states and like the LeasePlus New Home Solar Plan, the customer leases a solar energy system from us at a fixed monthly rate that is not subject to escalation throughout the term of the lease. We own, operate and maintain the solar energy system under our lease agreements. In most cases, lease agreements include a performance guarantee under which we will refund payments or credit the customer if the solar energy system fails to meet a guaranteed minimum level of power production for specified time periods.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *PPAs*. We offer PPAs with variable monthly payments or balanced monthly payments. We own, operate and maintain the solar energy system under our PPAs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Easy Plan PPA with variable billing*. The customer agrees to pay for all power generated by a solar energy system at a price per kWh that is generally lower than the local utility rate. The monthly payment will vary month to month based on the system's actual production. The monthly rate is generally subject to annual escalation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Easy Plan PPA with balanced billing*. This is similar to the variable billing option except the customer's payments are levelized over the course of a year based on an annual production estimate so the customer's payments are insulated from monthly fluctuations in energy production subject to a true-up at the end of such period. The fixed monthly rate is typically subject to annual escalation. Should the annual production estimate exceed actual production, the customer will receive a bill credit at the end of the applicable period and we may decrease the estimated production (and corresponding monthly payments) for the subsequent year. Should actual production exceed the annual estimate, we may apply the overproduction to a subsequent year or increase the estimated annual production and corresponding monthly payments for the subsequent year. The estimated annual production will not increase more than 110% from the estimated annual production for the first year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Solar 20/20 Plan Agreement & Covenants*. The customer agrees to pay for all power generated by a solar energy system at a price per kWh that is indexed to the local utility rate but is guaranteed to be at least 20% lower than the applicable utility's weighted-average rate that takes into account the customer's estimated production. The monthly payment will vary month to month based on the system's actual production and that month's indexed rate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Fixed Rate Power Purchase Agreement.* This is similar to the variable billing option except the monthly rate is fixed throughout the term of the agreement and not subject to annual escalation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Loan Agreements*. Pursuant to an Easy Own Plan equipment purchase agreement, the customer purchases the solar energy system from a dealer using financing provided by us. The customer repays the amount financed plus a finance charge through monthly payments for a term of 10, 15 or 25 years. We purchase the Easy Own Plan equipment purchase agreement from the dealer and agree to operate and maintain the solar energy system. We operate and maintain the solar energy system through our network of dealers. In most cases, Easy Own Plan equipment purchase agreements include a production guarantee under which we will refund payments or credit the customer if the solar energy system fails to meet a guaranteed minimum level of power production for specified time periods. Customers under our Easy Own Plan equipment purchase agreements have the option to prepay outstanding principal amounts, in part or in full, without penalty.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Energy Storage Systems*. Our Sunnova SunSafe program offers customers the option of a solar energy system integrated with a solar storage system. The customer can either choose an Easy Plan equipment lease or Easy Own Plan equipment purchase plan. These are similar to our Easy Plan equipment lease and Easy Own Plan equipment purchase for home solar services but include energy storage systems with the solar energy system. The customer may select a term of 10, 15 or 25 years for the Easy Own Plan equipment purchase. These agreements have a production guarantee for the solar energy system, similar to the home solar service Easy Plan equipment lease and Easy Own Plan equipment purchase plans, except in Guam, Saipan, Hawaii, Puerto Rico and Florida. Additionally, we offer the Sunnova +SunSafe agreement to existing customers in several states and territories, under which the customer purchases an energy storage system (to be used in connection with an existing solar energy system) from a dealer using

------

financing provided by us. Under the Sunnova +SunSafe agreement, the customer repays the amount financed plus a finance charge through monthly payments for a term of 10, 15 or 25 years.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Sunnova Loan*. The financing of energy-related products and services independent of a solar energy system was launched in the fourth quarter of 2021 to meet evolving and expanding customer needs (e.g. electric vehicle charging, home automation, security and energy management). We have established a niche amongst pure financing competitors by providing energy-related products and services with competitive rates and tenors. Where applicable, our products come with a standard manufacturer's warranty on equipment. Our Sunnova Loan offering gives our dealers the flexibility to offer additional products and services to customers outside of a traditional solar loan. Customers may select a pre-defined term ranging from 1 to 11 years.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Sunnova Protect Services*. For solar energy systems not owned or sold by us, our Sunnova Protect Services agreements provide customers maintenance and repairs as well as system monitoring and diagnostics. We provide two levels of service: (a) Basic, which is monitoring only and (b) Premium, which is monitoring plus repair and/or replacement of all equipment under a manufacturer's warranty. The customer may select the level of service and a term of 1, 5, 10 or 20 years. Prior to commencing coverage, we will run a diagnostic evaluation on the customer's solar energy system and will identify any underperforming equipment and estimate production. The customer may elect to repair underperforming equipment, on a time and materials basis, so that it may be included in the coverage going forward. Should the customer decline to repair the underperforming equipment, it will not be covered under the Sunnova Protect Services agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Sunnova Repair Services*. Through our Sunnova Repair Services, we provide repairs to solar energy systems and energy storage systems for out of warranty system repairs or to owners of solar energy systems and energy storage systems not owned or sold by us who do not have a service provider. Additionally, Sunnova Repair Services can address repairs not covered by warranties for both solar energy systems and energy storage systems owned or sold by us and solar energy systems and energy storage systems not owned or sold by us. The variety of repairs that Sunnova Repair Services may provide includes assessment and troubleshooting, warranty administration, warranty fulfillment, preventative maintenance and repair and replacement of equipment. Additionally, suppliers and financiers subscribe to Sunnova Repair Services for repairs on their behalf.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Accessory Purchase and/or Roof Replacement*. Customers have the option to purchase add-on accessories and services, including main panel upgrades, tree trimming, electric vehicle chargers and roof replacements, with financing options when bundled with a new Sunnova Home Solar Service or Sunnova SunSafe Solar + Battery Storage Service agreement.

As of December 31, 2022, approximately 24% of our customers had lease agreements, approximately 28% had PPAs, approximately 28% had loan agreements and approximately 17% had service plan agreements.

We have developed a standardized protocol and set of policies to qualify potential customers. During the solar energy system origination phase, we review the customer's credit application for compliance with our credit standards. Solar service agreements that are accepted must comply with our underwriting standards, which emphasize the prospective customer's ability to pay and the value of the customer's estimated savings under the solar service agreement compared to traditional utility rates. The exceptions are prospective purchasers of homes subject to the Easy Plan equipment lease, LeasePlus New Home Solar Plan, the Prepaid LeasePlus New Home Solar Plan, the Solar 20/20 Plan Agreement & Covenants and the Fixed Rate Power Purchase Agreement. These customers are not subject to credit checks and these agreements are freely transferable.

We maintain reporting and controls in place to monitor the timeliness of customer payments. As of December 31, 2022, approximately 88% of all payments received pursuant to our solar service agreements are collected via Automated Clearing House payments (i.e., the funds are deducted automatically on a monthly basis from the customer's bank account), approximately 7% are collected via automatic recurring credit card payments and approximately 5% are collected through non-recurring means. If a customer becomes delinquent on one or more monthly installment payments, we typically begin a collection process with respect to the customer.

In the event a customer elects to sell his or her home or business, the customer's solar service agreement may be transferred to the prospective purchaser through prescribed reassignment procedures, subject to certain conditions related to the prospective purchaser's creditworthiness. To initiate the reassignment process, the customer must notify us of the pending sale, after which we will provide a copy of the solar service agreement, including any amendments, to the prospective purchaser. The prospective purchaser will then be required to complete a customer profile and a credit application. With the exception of customers

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

originated through our homebuilder channel, each prospective purchaser's FICO<sup>®</sup> Score and Experian TEC (Telecommunications, Energy and Cable) Score will be evaluated on the same basis as a customer in a new origination and will be evaluated by our computer auto-decisioning system.

In the event a prospective purchaser does not meet our credit criteria or elects not to be subject to such credit inquiry, the current customer will be required to prepay the solar service agreement in full or the prospective purchaser will be required to provide a security deposit in cash in accordance with such customer's solar service agreement or our transfer policy prior to the approval of the reassignment. Each such security deposit is held in a separate account until the earlier of (a) the time at which the prospective purchaser satisfies our established credit criteria or (b) upon 12 consecutive months of on-time payments following the date of reassignment.

On a case-by-case basis, we may remove a solar energy system and, if applicable, energy storage system from the property on which it is installed if, among other reasons, the solar service agreement is canceled or otherwise terminated, the customer or solar energy system and energy storage system is relocated, any of the component parts are damaged or the new home or business owner rejects the reassignment of the solar service agreement upon location transfer, if applicable.

**Monitoring and Maintenance Service and Warranties**

Our solar service agreements typically are accompanied by a warranty and/or monitoring and service agreement. The warranty and monitoring services provided with each type of solar service agreement vary but can include operations and maintenance, equipment repairs, monitoring or site power controls and management for both supply and demand. Additionally, our Sunnova Protect program offers monitoring, service and facilitation of repairs across two tiers of service for solar energy systems owned by the home or business owner and installed by a third party.

Regardless of the type of our solar service agreement, we provide ongoing service during the entire term of the customer relationship, including monitoring, maintenance and warranty services of the solar energy system and energy storage system, if applicable. We have an operations and maintenance administration organization consisting of administration staff and a dedicated monitoring and production team that evaluates the solar energy systems' and energy storage systems' performance daily. When a performance or operation issue is detected via our monitoring system, we provide or arrange for troubleshooting or field services as necessary. We rely on our own personnel and our dealer network to complete the field services required to maintain the solar energy systems. After completion of the resolution steps, the maintenance administration organization verifies remotely the issue has been resolved and the system or energy service is performing as expected.

Additionally, customers under our solar service agreements receive a range of warranties on the related solar energy systems and energy storage systems, including warranties for module production and against defects in workmanship and against component or materials breakdown. We also provide the customers with a warranty on roof penetrations of up to 10 years in compliance with applicable state, territorial or local law. Through our agreements with our dealers, the dealer is generally obligated, at its sole cost and expense, to correct defects in its installation work for a period of up to 10 years and provide a roof warranty on roof penetrations of 5 to 10 years. Furthermore, we provide a pass-through of the solar photovoltaic panel manufacturers' warranty coverage to our customers, generally of 25 years, and of the inverter and energy storage system manufacturers' warranty coverage, typically of 10 to 25 years. We typically exercise our rights under the manufacturer's equipment warranties or dealer installation warranties before incurring direct charges or costs. Many service expenses are borne by our dealers and not us directly because of the workmanship warranty provided by the dealers to us. Additionally, many component costs are covered by manufacturer warranties.

**Seasonality**

The amount of electricity our solar energy systems produce is dependent in part on the amount of sunlight, or irradiation, where the assets are located. Because shorter daylight hours in winter months and poor weather conditions due to cloud cover, rain or snow results in less irradiation, the output of solar energy systems will vary depending on the season or the year. While we expect seasonal variability to occur, the geographic diversity in our assets helps to mitigate our aggregate seasonal variability.

Our Easy Plan PPAs with variable billing, Solar 20/20 Plan Agreements and Fixed Rate Power Purchase Agreements are subject to seasonality because we sell all the solar energy system's energy output to the customer at either a fixed price per kWh or indexed, variable rate per kWh. Our Easy Plan PPAs with balanced billing are not subject to seasonality (from a cash flow perspective or the customer's perspective) within a given year because the customer's payments are levelized on an annualized basis so we insulate the customer from monthly fluctuations in production. In addition, energy production true-ups and production estimate adjustments for Easy Plan PPAs with balanced billing are calculated over an entire year. However, our

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

Easy Plan PPAs with balanced billing are subject to seasonality from a revenue recognition perspective because, similar to the Easy Plan PPAs with variable billing, we sell all the solar energy system's energy output to the customer. Our lease agreements are not subject to seasonality within a given year because we lease the solar energy system to the customer at a fixed monthly rate and the reference period for any production guarantee payments is a full year. Finally, our loan agreements are not subject to seasonality within a given year because the monthly installment payments for the financing of the customers' purchase of the solar energy system are fixed and the reference period for any production guarantee is a full year.

In addition, weather may impact our dealers' ability to install solar energy systems and energy storage systems. For example, the ability to install solar energy systems and energy storage systems during the winter months in the Northeastern U.S. is limited. This can impact the timing of when solar energy systems and energy storage systems can be installed and when we can acquire and begin to generate revenue from solar energy systems and energy storage systems.

**Intellectual Property**

We rely on intellectual property laws, primarily a combination of copyright and trade secret laws in the U.S., as well as license agreements and other contractual provisions, to protect our proprietary technology. We also rely on several registered and unregistered trademarks to protect our brand. In addition, we generally require our employees and independent contractors involved in the development of intellectual property on our behalf to enter into agreements to limit access to, and disclosure and use of, our confidential information and proprietary technology. We also continue to expand our technological capabilities through licensing technology and intellectual property from third parties.

**Government Regulations**

While we are not regulated as extensively as a public utility where our business is conducted in the U.S., we are subject to various national, state, territorial and other local regulatory regimes. For example, in California and New York, we are subject to regulations concerning marketing and contracting promulgated by state public utility commissions. In some states, such as Arizona and Florida, we are limited to offering only a lease agreement or a loan agreement to homeowners and are prohibited from offering a PPA, which is deemed a retail sale of electricity in such states and can only be made by a regulated utility. In Puerto Rico, we are subject to regulation as an electric power company by the PREB and are required to comply with certain filing, certification, reporting and annual fee requirements. Regulation by the PREB as an electric power company does not currently subject us to centralized utility-like regulation or require the PREB's approval of charges to customers.

To operate the solar energy systems and energy storage systems, our dealers work with customers to obtain interconnection permission from the applicable local electric distribution utility. In many states and territories, by statute, regulations or administrative order, there are standardized procedures for interconnecting distributed solar energy systems and related energy storage systems to the electric utility's local distribution system. In some states, such as New Jersey and Massachusetts, certain utilities, such as municipal utilities or electric cooperatives, are exempt from some interconnection requirements. Provided that the system and energy, if applicable, qualify for the standardized procedures based upon size, use of industry-standard components, location on a suitable local network and other applicable requirements, utilities in such states or territories are required to interconnect qualifying solar energy systems and energy storage systems on an expedited basis relative to non-qualifying systems. Expedited procedures, when available, streamline the installation and interconnection process for solar energy systems and energy storage systems to begin operating. In the U.S. states and territories in which we operate, our dealers typically obtain interconnection permission on behalf of us and our customers using standardized interconnection procedures.

In certain states, such as California, independent solar energy producers who enter into lease agreements, PPAs or loan agreements with home and business owners for solar energy systems are required to make certain disclosures to the home or business owner regarding the solar energy system and the terms of the agreement and record a notice against the title to the real property on which the electricity is generated and against the title to any adjacent real property on which the electricity will be used. The notice does not constitute a title defect, lien or encumbrance against the real property.

Our operations, as well as the operation of our dealers, are subject to stringent and complex federal, state, territorial and local laws, including regulations governing the occupational health and safety of employees, wage regulations and environmental protection. For example, we and our dealers are subject to the regulations of the U.S. Department of Labor, Occupational Safety and Health Administration ("OSHA"), the U.S. Department of Transportation ("DOT"), the U.S. Environmental Protection Agency ("EPA") and comparable state and territorial entities that protect and regulate employee health and safety and the environment. These include, for example, regulations regarding the disposal of solid and hazardous wastes from the solar energy systems we own. In addition, environmental laws can result in the imposition of liability in connection with end-of-life system disposal, such as in connection with disposal and recycling of batteries.

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

We and our dealers are also subject to laws and regulations related to interactions with consumers, including those pertaining to sales and trade practices, privacy and data security, equal protection, consumer financial and credit transactions, consumer collections, mortgages and re-financings, home or business improvements, trade and professional licensing, warranties and various means of customer solicitation, as well as specific regulations pertaining to solar installations.

For a discussion of these and other regulatory requirements, see "*Risk Factors*—*Risks Related to Regulations*".

**Government Incentives**

U.S. federal, state, territorial and local governments have established various incentives and financial mechanisms to reduce the cost of solar energy and to accelerate the adoption of solar energy. These incentives come in various forms, including rebates, tax credits and other financial incentives such as payments for renewable energy credits associated with renewable energy generation, exclusion of solar energy systems and energy storage systems from property tax assessments, system performance payments, accelerated depreciation and net energy metering, or net metering, programs. These incentives make solar energy system and energy storage system ownership more attractive to some home and business owners and enable us to charge our customers lower prices to purchase energy generated by our solar energy systems and energy storage systems or to lease or purchase our solar energy systems and energy storage systems than they would normally be expected to pay for utility-provided energy. These incentives also help catalyze private sector investments in solar energy and efficiency measures, including the installation and operation of residential and commercial solar energy systems and energy storage systems.

Net metering is one of several key policies that have enabled the growth of distributed solar in the U.S., providing significant value to certain customers with solar energy systems for the electricity generated by their systems but not directly consumed on site. Net metering allows a customer to pay the local electric utility only for power usage net of excess production from the customer's solar energy system. Customers receive a credit for the energy an interconnected solar energy system generates in excess of that needed by the home or business, which is provided to the electrical grid. The credit offsets energy usage incurred by the customer at times when the customer requires more electricity than is generated by the solar energy system. In many markets, this credit is equal to the residential retail rate for electricity and in other markets the rate is less than the retail rate and may be based, for example, in whole or in part on the centralized electric utility's "avoided cost" for electricity that it would have had to generate or purchase at wholesale to meet the customer's demand. Furthermore, when coupled with a time of use rate program in certain electric utility territories, a home or business owner may offset usage billed at lower rates with net metering credits provided at a higher rate.

For these reasons, net metering credits incentivize consumers to use distributed solar in certain jurisdictions, including some of those in which we operate. In some electric utility territories, any excess credits are rolled over to the next billing period and may also be cashed out later at a rate lower than the retail rate. Most states, the District of Columbia, Puerto Rico and Guam have adopted some form of net metering by statute, regulation, administrative order or a combination thereof, although some of these jurisdictions provide for a credit at less than the retail rate. In some jurisdictions, centralized electric utilities have also adopted net metering on a voluntary basis. Some of the states in which we operate, including New Jersey, Maryland, Massachusetts, Rhode Island, Delaware, Illinois and Hawaii, have in place policies that limit or permit utilities to limit the amount of total electricity generated through net metering and/or solar energy systems, and some of these states, as well as other states or territories, including Pennsylvania, Nevada, New Mexico and Guam, have policies that limit or place conditions on the size of individual solar energy systems.

Net metering and other incentive programs are subject to legislative and regulatory review in many states and territories in which we operate, and the availability and value of these programs could be limited, reduced or phased out. Some states such as Arizona, Nevada, California and Kentucky have reduced their net metering credits. Further reviews by these states and others are anticipated and the subsequent amount of net metering credits will continue to be assessed over the next few years in states that have net metering policies. For example, net metering rates in Puerto Rico and South Carolina are up for consideration currently or over the next few years.

In December 2022, the CPUC approved a successor program to its current net metering program that reduces the value of net metering credits from the retail rate to an avoided cost rate for customers that will have solar energy systems installed on their homes and businesses over the next five years. Customers will also be placed on an electrification rate. Residential customers located in the territories of two of the investor-owned utilities will also receive small adders to the avoided cost rate, while the residential customers in the territory of the third investor-owned utility, as well as new homes and commercial customers in all three of the service territories, do not receive any adders. In addition, it may only be possible for customers to realize savings from installing solar energy systems compared to the utility retail rate by adding storage to their solar energy systems or undersizing them so exports are limited. The decision goes into effect in April 2023.

New York is working on developing an alternative to net metering through a Value of Distributed Energy Resources credit that would allow certain customers to receive direct monetary compensation as opposed to a net metering credit. This program was expected to be implemented in 2021 but has been delayed due to not enough utilities having deployed smart meters that would enable an accurate valuation of distributed energy production. New York is keeping net metering in place with a nominal customer benefit charge added for solar customers who have solar energy systems installed after January 1, 2022, although that charge is undergoing a legal challenge and legislation has been introduced that would eliminate it entirely. As a result of the Definitive Restructuring Support Agreement ("DRSA") between the PREPA and its creditors submitted in May 2019, which is currently pending before the U.S. District Court for the District of Puerto Rico, net metering customers in Puerto Rico may be impacted by transition charges and other requirements. Several legislators publicly oppose the DRSA and negotiations on the DRSA continued throughout 2022.

In September 2020, the Federal Energy Regulatory Commission ("FERC") issued Order 2222 directing regional transmission operators ("RTO") and independent system operators ("ISO") to remove barriers to the participation of distributed energy resources ("DERs") in wholesale electricity markets on an aggregated basis. While the FERC's order is subject to challenge as well as further proceedings concerning the implementation of the order's directives in each of the RTOs/ISOs, Order 2222 provides a framework that once implemented will allow for aggregated DERs to be compensated through the wholesale market for the capacity, energy and ancillary services they provide.

In late 2020, we began offering our lease storage customers participation in the ConnectedSolutions demand response program through EverSource and National Grid utilities in Massachusetts. We expanded these offerings for our Connecticut, Rhode Island and New Hampshire customers in early 2021, including loan storage customers. Our storage customers in California have the option to participate in the demand response market to help California manage its electricity demand, where we manage the battery storage system in response to price signals in the energy market for customers served by Pacific Gas and Electric Company and San Diego Gas & Electric utilities and work with Clean Power Alliance in Southern California Edison territory to provide demand response and resource adequacy. Additionally, we are leading a voltage support pilot within National Grid's service territory where a portion of its fleet is increasing efficiency of the distribution network through a managed inverter program. Further, we will seek to participate in market specific opportunities and negotiate bilateral agreements, where appropriate, to enroll systems and customers in energy management and demand response programs.

Many states and territories have adopted renewable portfolio energy production requirements. The majority of states, the District of Columbia and Puerto Rico have adopted a renewable portfolio standard ("RPS") that requires regulated electric utilities to generate or procure a specified percentage of total electricity delivered to customers in the state or territory from eligible renewable energy sources, such as solar energy systems, by a series of specified dates. In addition, several other states have set voluntary goals for renewable generation.

Roughly one-third of states with RPS policies require a minimum portion of the RPS be met by electric generation from solar energy systems, with substantial penalties for non-compliance. To demonstrate compliance with such RPS mandates, electric generation providers must submit SRECs to the applicable authority. One SREC is produced by one megawatt-hour of energy generated by an eligible solar energy system. The specified amount of energy is dependent on system size and when the solar energy system receives a "permission to operate" order. Electric generation providers can either generate their own SRECs through solar energy systems they own or they can purchase SRECs owned by other parties.

SRECs are a distinct product, separate from the electricity generated by solar energy systems. We and our customers apply for and receive SRECs in certain jurisdictions for power generated by the solar energy systems we own. As a distinct product from the electricity generated by solar energy systems, SRECs represent a separate source of cash flow from the sale of electricity. SRECs can be sold with or without the actual electricity associated with the renewable-based generation. Solar energy system owners are typically able to sell SRECs to electric generation providers, such as electric utilities, or in the SREC commodity market. We have hedged a portion of our expected SREC production under fixed price forward contracts. The forward contracts require us to physically deliver the SRECs upon settlement.

Several states have an energy storage mandate or policies designed to encourage the adoption of storage. For example, California offers a cash rebate for storage installations through the Self Generation Incentive Program and Massachusetts and New York offer performance-based financial incentives for storage. Storage installations also are supported in certain states by state public utility commission policies that require utilities to consider alternatives such as storage before they can build new generation. In February 2018, the FERC issued Order 841 directing RTOs and ISOs to remove barriers to the participation of storage in wholesale electricity markets and to establish rules to help ensure storage resources are compensated for the services they provide. An appeal of Order 841 filed by utility trade associations and other parties challenging the extent of the FERC's jurisdiction over storage resources connected to distribution systems was rejected by the U.S. Court of Appeals for the D.C. Circuit in July 2020.

Some state and territorial governments, centralized electric utilities, municipal utilities and co-operative utilities offer a cash rebate or other payment incentive for the installation and operation of a solar energy system or energy storage system or to customers undertaking other energy efficiency measures. Capital cost or "up-front" rebates provide funds to solar customers or developers or solar energy system owners, such as us, based on the cost, size or expected production of a customer's solar energy system. Performance-based incentives and tariff-based incentives provide payments to solar customers or a solar energy system owner based on the energy generated by the solar energy system during a pre-determined period. These rebates and payment incentives, when available, improve the economics of distributed solar to both us and our customers.

The economics of purchasing a solar energy system and energy storage system are also improved by eligibility for accelerated depreciation, which allows for the depreciation of equipment according to an accelerated schedule set forth by the IRS. This accelerated schedule allows a taxpayer to recognize the depreciation of tangible solar property on a five-year basis even though the useful life of such property is greater than five years. The acceleration of depreciation creates a valuable tax benefit that increases the return on investment from a solar energy system and energy storage system. We benefit from accelerated depreciation on the solar energy systems and energy storage systems we own.

The federal government currently provides business investment tax credits under Section 48(a) (the "Section 48(a) ITC") and, for projects that begin construction after December 31, 2024, under Section 48E (the "Section 48E ITC") as well as residential energy credits under Section 25D (the "Section 25D Credit") of the U.S. Internal Revenue Code of 1986, as amended (the "Code"). In August 2022, the Inflation Reduction Act of 2022 (the "IRA") was signed into law. Among other things, the IRA expanded and extended the tax credits available to solar energy projects in an effort to achieve President Biden's non-binding target of net-zero emissions by 2050. The IRA extends the investment tax credit for eligible solar energy projects through at least 2033 and, depending on the location of a particular project, its size, its ability to satisfy certain labor and domestic content requirements and the category of consumers it serves, the investment tax credit percentage can range between 6% and 70%. For projects that begin construction after December 31, 2024, the Section 48(a) ITC will be replaced with the Section 48E ITC, a new clean energy investment tax credit, and the Section 48E ITC percentage will be the same as the percentage for the Section 48(a) ITC and subject to the same requirements to benefit from the full 30%. Following passage of the IRA, retroactive to the beginning of 2022, we are able to claim the Section 48(a) ITC or the Section 48E ITC, as applicable, for energy storage systems whether attached to a solar energy system or stand-alone.

The IRA also allows qualifying homeowners who purchase a residential solar energy system and/or energy storage system to deduct up to 30% of the cost of installing those systems from their U.S. federal income taxes, thereby returning a material portion of the purchase price of the residential solar energy system and/or energy storage system to homeowners. Under the terms of the current extension, the Section 25D Credit will remain at 30% through the end of 2032, reduce to 26% for 2033, reduce to 22% for 2034 and further reduce to 0% after the end of 2034, unless it is extended before that time.

Certain states and territories in which we operate offer a personal and/or corporate investment or production tax credit for solar energy. Further, most of the states and local jurisdictions have established sales and/or property tax incentives for renewable energy systems that include exemptions, exclusions, abatements and credits. For a discussion of these and other governmental incentives, see "*Risk Factors*—*Risks Related to Regulations*".

**Competition**

We believe our primary competitors are centralized electric utilities that supply electricity to our potential customers. We compete with these centralized electric utilities primarily based on price (cents per kWh), predictability of future prices (by providing pre-determined annual price escalations, where applicable), reliability and the ease by which customers can switch to electricity generated by solar energy systems. We believe we compete favorably with centralized electric utilities based on these factors in the states and territories where our solar service agreements are offered.

We also compete with retail electric providers and independent power producers that are not regulated like centralized electric utilities but have access to the centralized utilities' electricity transmission and distribution infrastructure pursuant to state, territorial and local pro-competitive and consumer choice policies. Furthermore, we compete with solar companies with vertically integrated business models, such as Sunrun Inc. and SunPower Corporation. In addition, we compete with other solar companies who sell or finance products directly to consumers, inclusive of programs like Property-Assessed Clean Energy, such as Goodleap, LLC and Mosaic, Inc. For example, we face competition from solar installation businesses that seek financing from external parties or utilize competitive loan products or state and local programs. In the future, we may also compete with solar companies that have business models similar to our own, some of which are marketed to potential customers by our dealers. We compete with these companies based on the competitiveness of the products, the overall customer relationship and the commissions we are willing to pay dealers for the origination of new customers.

**Suppliers**

The major components of the solar energy systems include (a) solar photovoltaic panels that turn sunlight into direct current ("DC") electricity, (b) inverters that convert solar-generated DC electricity into alternating current ("AC") electricity, the form of energy used by most standard household appliances, (c) racking systems that attach the solar photovoltaic panels to the roof or ground, (d) a remote monitoring system that measures and monitors all energy generated by the solar energy system and provides alerts about system performance and (e) in some cases, an energy storage system that stores excess energy generated by the photovoltaic panels to supplement energy supply during hours when energy consumption exceeds energy produced by the photovoltaic panels. The solar energy system may also be connected to the electrical grid or other supplemental energy sources, such as fuel cells and generators, with additional wiring and electrical hardware.

We require our dealers to choose all major components of the solar energy system or energy storage system from a pre-approved list of manufacturers and models. By allowing dealers to choose from several manufacturers and models without direct supplier obligations, we have greater flexibility to satisfy customer demand, ensure competitive pricing and adequate supply of components and reduce the concentration of warranty risks. We have entered into master contractual arrangements with each vendor on our pre-approved list of vendors that defines the general terms and conditions of our purchases and those of our dealers, including warranties, product specifications, indemnities, delivery and certain other terms. Our dealers typically purchase solar panels and inverters on an as-needed basis from our pre-approved suppliers at then-prevailing prices pursuant to purchase orders having the benefit of our master contractual arrangements. At times, we will also procure equipment directly and sell it to our dealers.

For installations of solar energy systems on new homes or businesses, we negotiate pricing directly with the manufacturers for all components used in the solar energy systems. Based upon our production planning model, we position and deliver the material on a just-in-time basis to our dealers to meet the builder requirements.

We evaluate and qualify our manufacturers and their product offerings based on total cost of ownership, reliability, warranty coverage, credit quality and other factors. All equipment must be listed on the California Energy Commission's SB1 List of Eligible Equipment. All approved solar photovoltaic panels must have a minimum 25-year power warranty and 10-year workmanship warranty. We also require approved solar photovoltaic panels to undergo extended reliability testing as an indication of a 25-year or greater lifetime. Beginning in April 2016, we required all our manufacturers carry a 25-year warranty, or offer a warranty extension to 25 years, on all product offerings to be eligible for inclusion on our approved vendor list. Prior to April 2016, we sourced inverter manufacturers offering a warranty of no less than 10 years. All approved racking systems are required to be solar energy system Fire Class Rated "A" with a Type 1 module per California Fire requirements. Additionally, the racking system must have a Professional Engineers stamp as proof of structural analysis and wind speed certification and the racking system must be certified as conforming to the integrated grounding and bonding requirements of UL Subject 2703. All replacement parts and components must meet or exceed the same standards as those of the original installation.

In September 2018, the Office of the United States Trade Representative ("USTR") determined to modify its prior actions in its investigation into certain acts, policies and practices of the government of China related to technology transfer, intellectual property and innovation pursuant to Section 301 of the Trade Act of 1974 by imposing an additional 10% duty on $200 billion worth of products from China, including inverters. In May 2019, the tariffs were increased from 10% to 25% and may be raised by the USTR in the future. If inverter production is not shifted to other countries before any tariff rate increase on these products, the price of inverters could increase. However, the cost of solar photovoltaic panels and inverters generally do not comprise a meaningful portion of our operating expenses. In addition, many of the solar photovoltaic panel and inverter manufacturers on our approved vendor list are from countries other than China, including Canada, the U.S., Mexico, Vietnam and Malaysia. See "*Risk Factors—Risks Related to the Solar Industry—Increases in the cost or reduction in supply of solar energy system and energy storage system components due to tariffs or trade restrictions imposed by the U.S. government could have an adverse effect on our business, financial condition and results of operations".* These tariffs have not had a material impact on our business or our operations.

**Human Capital Management**

Our core company values are service, synergy and sustainability. Our core value of service reflects our belief in providing a better energy service to the communities we serve. Our core value of sustainability reflects our belief we do well by doing good. Our core value of synergy reflects our belief we can achieve more by working together. We are focused on collectively advancing Sunnova and the energy industry through collaboration, integrity, respect and long-term trusted relationships, which includes our relationship with our employees.

*Oversight and Management*

We recognize the diversity of our customers, employees and communities, and believe in creating an inclusive and equitable environment that represents a broad spectrum of backgrounds and cultures. Working under these principles, our human resources department is tasked with managing employment-related matters, including recruiting and hiring, onboarding and training, retention, employee relations, compensation and benefits planning, performance management and professional development. Our Board and its committees provide oversight on certain human capital matters, including our inclusion and diversity programs and initiatives. Our management team regularly reports to the Board regarding programs and initiatives, including compensation, healthcare and other benefits, turnover and retention, as well as our management development and succession planning practices and strategies. Our audit committee works closely with our enterprise risk management function to monitor current and emerging labor and human capital management risks and to mitigate exposure to those risks. Our nominating and corporate governance committee has oversight of our environmental, social and corporate governance practices and procedures and regularly evaluates the effectiveness of our social responsibility policies, goals and programs, which also include employee-related issues. Our compensation and human capital committee has oversight of the development, implementation and effectiveness of all pay and benefit programs, as well as succession planning. These reports and recommendations to the Board and its committees and their oversight are part of the broader framework that guides how Sunnova attracts, retains and develops a workforce that aligns with our values and strategies.

Each employee is required to complete certain compliance training each year that reinforces company policy and culture, including our anti-harassment and anti-discrimination policies. We regularly conduct anonymous surveys to seek feedback from our employees on a variety of topics, including but not limited to, confidence in company leadership, competitiveness of our compensation and benefits package, career growth opportunities and improvements on how we could make our company an employer of choice. The results are shared with our employees and reviewed by senior leadership, who analyze areas of progress or deterioration and prioritize actions and activities in response to this feedback to drive meaningful improvements in employee engagement. Our management and cross-functional teams also work closely to evaluate human capital management issues, such as retention, harassment and bullying and safety, as well as to implement measures to mitigate these risks. Our Chief Executive Officer ("CEO") regularly holds townhalls with employees to discuss operating results, announce important initiatives, recognize employees for years of service milestones and respond to employee questions. Employees are also encouraged to report compliance and ethics issues through our anonymous hotline if they feel uncomfortable speaking directly to their supervisor or management.

*Comprehensive Benefits*

We believe in investing in our workforce by offering competitive salaries and wages. We also offer comprehensive and competitive benefits to protect the health, wellbeing and financial security of our employees. To foster a stronger sense of ownership and align the interests of employees with our stockholders, eligible non-executive employees are able to participate in our broad-based stock incentive program and all employees are eligible to participate in our employee stock purchase plan.

*Training and Support*

To help our employees succeed in their roles, we emphasize continuous training and development opportunities. These opportunities are offered through e-learning, online/classroom training, online performance management and goal setting, one-on-one coaching, individual development planning and group training initiatives and cover a variety of topics, such as ethics, code of conduct, insider trading and workplace harassment.

*Safety*

We take our responsibility to ensure the health and safety of our employees very seriously. Our objective is for each of our employees and contractors to go home each day free from work-related accidents and injuries, which are costly and often preventable. To that end, we have developed a detailed safety program that includes, but is not limited to, protocols and procedures governing working at heights, roof safety, motor vehicle safe driving operations, electric shock mitigation and pre-storm weather hazard monitoring in the areas in which we operate.

*Employee Base*

As of December 31, 2022, we had 1,170 full-time employees and 1,173 total employees. We also engage independent contractors and consultants. We are not party to any collective bargaining agreements and have not experienced any strikes or work stoppages.

**Item 1A. Risk Factors.**

Investing in our common stock involves a high degree of risk. You should carefully consider the risks described below together with all of the other information included in this Annual Report on Form 10-K, including the section titled "*Management's Discussion and Analysis of Financial Condition and Results of Operations*" and our annual audited consolidated financial statements ("consolidated financial statements") and related notes, before deciding to invest in our common stock. We may experience additional risks and uncertainties not currently known to us; or, as a result of developments occurring in the future, conditions that we currently deem to be immaterial may also materially and adversely affect our business, financial condition, cash flows and results of operations. If any of the risks actually occur, they may materially and adversely affect our business, financial condition, cash flows and results of operations. In this event, the trading price of our common stock could decline and you could lose all or part of your investment in us.

**Risks Related to Our Business**

***Historically, we have incurred operating and net losses and we may be unable to achieve or sustain profitability in the future.***

We incurred operating losses of $81.5 million, $54.9 million and $35.8 million and net losses of $130.3 million, $147.5 million and $307.8 million for the years ended December 31, 2022, 2021 and 2020, respectively. These historical operating and net losses were due to a number of factors, including increased expenses to fund our growth and related financing needs. We expect to incur significant expenses as we finance the expansion of our operations and implement additional internal systems and infrastructure to support our growth. We do not know whether our revenue will grow rapidly enough to absorb these costs. Our ability to achieve profitability depends on a number of factors, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;growing our customer base and originating new solar service agreements on economic terms;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;maintaining or lowering our cost of capital;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;reducing operating costs by optimizing our operations and maintenance processes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;maximizing the benefits of our dealer network;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;finding additional tax equity investors and other sources of institutional capital; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;the continued availability of various governmental incentives for the solar industry.

Even if we do achieve profitability, we may be unable to sustain or increase our profitability in the future.

***Our growth strategy depends on the continued origination of solar service agreements by us and our dealers.***

Our growth strategy depends on the continued origination of solar service agreements by us and our dealers. We may be unable to originate additional solar service agreements and related solar energy systems and energy storage systems in the numbers or at the pace we currently expect for a variety of reasons, including, among other things, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;demand for solar energy systems and energy storage systems failing to develop sufficiently or taking longer than expected to develop;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;solar energy technology being available at economically attractive prices as a result of factors outside of our control, including utility prices not rising as quickly as anticipated;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;issues related to identifying, engaging, contracting, compensating and maintaining relationships with dealers and the negotiation of dealer agreements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;issues related to financing, construction, permitting, the environment, governmental approvals and the negotiation of solar service agreements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;a reduction in government incentives or adverse changes in policy and laws for the development or use of solar energy, including net metering, SRECs and tax credits;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;other government or regulatory actions that could impact our business model;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;negative developments in public perception of the solar energy industry; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;competition from other solar companies and energy technologies, including the emergence of alternative renewable energy technologies.

If the challenges of originating solar service agreements and related solar energy systems and energy storage systems increase, our pool of available opportunities may be limited, which could have a material adverse effect on our business, financial condition, cash flows and results of operations.

***If we fail to manage our operations and growth effectively, we may be unable to execute our business plan, maintain high levels of customer service or adequately address competitive challenges.***

We have experienced significant growth in recent periods measured by our number of customers and we intend to continue our efforts to expand our business within existing and new markets. This growth has placed, and any future growth may place, a strain on our management, operational and financial infrastructure. Our growth requires our management to devote a significant amount of time and effort to maintain and expand our relationships with customers, dealers and other third parties, attract new customers and dealers, arrange financing for our growth and manage our expansion into additional markets.

In addition, our current and planned operations, personnel, information technology and other systems and procedures might be inadequate to support our future growth and may require us to make additional unanticipated investments in our infrastructure. Our success and ability to further scale our business will depend, in part, on our ability to manage these changes in a cost-effective and efficient manner.

If we cannot manage our operations and growth, we may be unable to meet our expectations regarding growth, opportunity and financial targets, take advantage of market opportunities, execute our business strategies, meet our tax equity financing commitments or respond to competitive pressures. This could also result in declines in quality or customer satisfaction, increased costs, difficulties in introducing new offerings or other operational difficulties. Any failure to effectively manage our operations and growth could adversely impact our reputation, business, financial condition, cash flows and results of operations.

***Our growth is dependent on our dealer network and our failure to retain or replace existing dealers or to grow our dealer network could adversely impact our business.***

Our dealer network is an integral component of our business strategy and serves as the means by which we are able to originate solar service agreements and related solar energy systems and energy storage systems in existing and prospective markets. Poor performance by our dealers in originating solar service agreements could have a material adverse effect on our business, financial condition and results of operations. We have in the past had disputes and litigation with certain of our dealers over their performance.

As we grow, particularly in new jurisdictions, we will need to expand our dealer network. We are subject to significant competition for the recruitment and retention of dealers from our competitors and we may not be able to recruit new or replacement dealers in the future. We compete for our dealers with other solar service providers primarily based on the amount and timing of payments for originating solar service agreements, financial ability and our suite of technology tools.

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

Most of our dealers are not restricted in their ability to work with our competitors and are not obligated to continue working with us. In the past, some of our dealers have chosen to work with competitors of ours or terminated their relationships with us and dealers may reduce or terminate their work with us in the future. The departure of a significant number of our dealers for any reason, or the failure to replace departing dealers in the event of such departures, could reduce our potential origination opportunities and could have a material adverse effect on our business, financial condition and results of operations. As we develop and expand our Sunnova Protect services, dealers may view us as a competitor and choose to end their relationship with us.

Additionally, dependence on any one dealer or small group of dealers further concentrates our exposure to risks related to termination of the dealer arrangement, poor service provided by such dealer, the deterioration in financial condition of the dealer and other risks inherent in such a relationship. For the years ended December 31, 2022, 2021 and 2020, Trinity accounted for approximately 19%, 15% and 28% of our net originations, respectively. Although we have entered into a sixty-six month exclusivity agreement with Trinity, pursuant to which Trinity may only originate solar service agreements for us, there are various exceptions to this obligation. For a discussion of exclusivity arrangements with certain of our dealers, see "*Business*—*Our Relationships with Our Dealers*".

***If we or our dealers fail to hire and retain a sufficient number of employees and service providers in key functions, our growth and our ability to timely complete customer projects and successfully manage customer accounts would be constrained.***

To support our growth, we and our dealers need to hire, train, deploy, manage and retain a substantial number of skilled employees, engineers, installers, electricians and sales and project finance specialists. Competition for qualified personnel in our industry has increased substantially, particularly for skilled personnel involved in the installation of solar energy systems. We and our dealers also compete with the homebuilding and construction industries for skilled labor. These industries are cyclical and when participants in these industries seek to hire additional workers, it puts upward pressure on our and our dealers' labor costs. Companies with whom our dealers compete to hire installers may offer compensation or incentive plans that certain installers may view as more favorable. As a result, our dealers may be unable to attract or retain qualified and skilled installation personnel. The further unionization of our industry's labor force or the homebuilding and construction industries' labor forces could also increase our dealers' labor costs. Shortages of skilled labor could significantly delay a project or otherwise increase our dealers' costs. Further, we need to continue to increase the training of our customer service team to provide high-end account management and service to home and business owners before, during and following the point of installation of our solar energy systems. Identifying and recruiting qualified personnel and training them requires significant time, expense and attention. It can take several months before a new customer service team member is fully trained and productive at the standards we have established. If we are unable to hire, develop and retain talented customer service or other personnel, we may not be able to grow our business.

***We do not directly control certain costs related to our business, which could put us at a disadvantage relative to companies who have a vertically integrated business model.***

We do not have direct control over the costs our suppliers charge for the components of our solar energy systems and energy storage systems or the costs to our dealers of installing and marketing such products. This may lead us to charge higher prices for our solar energy systems and energy storage systems than our competitors with a vertically integrated business model, causing us to be unable to maintain or increase market share.

***We may be unsuccessful in introducing new service and product offerings, including our distributed energy storage services and energy storage management systems.***

We intend to introduce new offerings of services and products to both new and existing customers in the future, including home automation products and additional home technology solutions. We may be unsuccessful in significantly broadening our customer base through the addition of these services and products within our current markets or in new markets we may enter. Additionally, we may not be successful in generating substantial revenue from any additional services and products we may introduce in the future and may decline to initiate new product and service offerings.

***Our business is concentrated in certain markets, putting us at risk of region-specific disruptions.***

As of December 31, 2022, approximately 33%, 16% and 12% of our customers were located in California, Puerto Rico and New Jersey, respectively. In addition, we expect much of our near-term future growth to occur in these same markets, further concentrating our customer base and operational infrastructure. Accordingly, our business and results of operations are particularly susceptible to adverse economic, regulatory, political, weather and other conditions in such markets and in other

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

markets that may become similarly concentrated. See "*—Certain of our solar energy systems are located in, and we conduct business in, Puerto Rico. Weakness in the fiscal health of the government and PREPA, the damage caused by hurricanes, a series of earthquakes that affected the island in December 2019 and early 2020 and potential tax increases that may increase our cost of conducting business in Puerto Rico, create uncertainty that may adversely impact us. In addition, we are subject to administrative proceedings instituted by the PREB*" and "*General Risk Factors—We are not able to insure against all potential risks and we may become subject to higher insurance premiums*". Any of these conditions, even if only in one such market, could have a material adverse effect on our business, financial condition and results of operations. In addition, all of our current solar energy systems are located in the U.S. and its territories, which makes us particularly susceptible to adverse changes in U.S. tax laws.

Our corporate and operational headquarters is located in Houston, Texas, an area that has a heightened risk of hurricanes and other natural disasters. We may not have adequate insurance, including business interruption insurance, to compensate us for losses that may occur from any such significant events. A significant natural disaster, such as a hurricane, a public health crisis, such as a pandemic, or civil unrest could have a material adverse impact on our business, results of operations and financial condition. In addition, acts of terrorism or malicious computer viruses could cause disruptions in our or our dealers' businesses or the economy as a whole. To the extent these disruptions result in delays or cancellations of installations or the deployment of our solar service offerings, our business, results of operations and financial condition would be adversely affected.

***Certain of our solar energy systems are located in, and we conduct business in, Puerto Rico. Weakness in the fiscal health of the government and PREPA, the damage caused by hurricanes, a series of earthquakes that affected the island in December 2019 and early 2020 and potential tax increases that may increase our cost of conducting business in Puerto Rico, create uncertainty that may adversely impact us. In addition, we are subject to administrative proceedings instituted by the PREB.***

Puerto Rico is a significant market for our business, representing 16% and 13% of our customers as of December 31, 2022 and 2021, respectively, and has suffered from significant economic difficulties in recent years. As a result of the continued weakness of the Puerto Rico economy, liquidity constraints and a lack of market access, the credit ratings of the Puerto Rico government's general obligation bonds and guaranteed bonds, as well as the ratings of most of the Puerto Rico public corporations, including PREPA, are non-investment grade by Moody's, S&P and Fitch Ratings.

Puerto Rico has also enacted certain measures that could increase the cost of solar energy systems. In 2015, the Puerto Rico government increased the sales and use tax from 7% to 11.5%. Although leases are currently exempt from such sales and use tax pursuant to Act No. 83-2010, the increase in sales tax is applicable to repair and maintenance services. Additionally, in October 2015, Puerto Rico enacted a 4% sales tax to previously exempt business-to-business transactions. Should our current exemption expire or additional taxes be imposed, the tax increase may impose greater costs on our future and current customers, which may hinder our future origination efforts and adversely impact our business, financial condition, results of operations and future growth. Future changes in Puerto Rico tax law could affect our tax position and adversely impact our business.

Although Puerto Rico had already suffered from economic difficulties in recent years, Hurricane Fiona in 2022 and Hurricanes Irma and Maria in 2017, catastrophic weather events whose effects have been long enduring, earthquakes in the southwest of the island beginning in 2019 and continuing through 2020 and the COVID-19 pandemic have caused significant additional disruption to the island's electric grid and economic activity. The continued weakness of the Puerto Rico economy has strained the fiscal health of the government, which may create uncertainty that may adversely impact us. Furthermore, the future financial condition and prospects of PREPA are uncertain, which could negatively impact the availability and the reliability of Puerto Rico's electrical grid and adversely impact our operations on the island.

In 2018, the government of Puerto Rico enacted legislation that set in motion the privatization of PREPA. Said legislation governs the establishment of public-private partnerships ("P3") with respect to the concession for the distribution and transmission assets, services and facilities of PREPA, including its generation assets. In the summer of 2020, the government of Puerto Rico signed a 15-year P3 agreement with LUMA Energy, LLC to operate, maintain and modernize PREPA's electric transmission and distribution system. Moreover, in November 2020, the government announced that several companies had been qualified as part of the procurement process related to the Request for Qualifications for the management and operation of PREPA's legacy generation assets. In January 2023, the management and operation of PREPA's legacy generation assets was awarded to Genera PR, LLC, a wholly owned subsidiary of New Fortress Energy Inc.

Legislation enacted in April 2019 requires a study of net metering to be completed within five years, which may result in revisions to the existing rules. However, no changes can be made to retail net metering for five years after the date the legislation was enacted. Meanwhile, "true" net metering will continue to apply, meaning the credit for energy exported by net

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

metering clients will equal the value of such energy under the rate applicable to those clients and accordingly, their charges will be based on their net consumption. Customers subject to this regime will continue to be covered by it on a legacy basis for a period of 20 years from the date of their net metering agreements.

Net metering customers in Puerto Rico may be impacted by transition charges and other requirements contemplated in a restructuring agreement between PREPA and its creditors, currently pending before the U.S. District Court for the District of Puerto Rico in bankruptcy-like proceedings under Title III of the Puerto Rico Oversight, Management, and Economic Stability Act ("PROMESA"). PROMESA provides PREPA with access to a workout process similar to bankruptcy. In response to the effects of the COVID-19 pandemic, however, the approval of the restructuring agreement has been stayed, and the government announced in December 2020 that it continues to conduct diligence to determine whether, among other things, the terms of the restructuring agreement should be renegotiated and the parameters for doing so.

While we do not currently contract directly with the Puerto Rico government or PREPA, continued weakness in the Puerto Rico economy or the failure of the Puerto Rico government to manage its fiscal challenges in an orderly manner could result in policy decisions we do not anticipate and may directly or indirectly adversely impact our business, financial condition and results of operations. In addition, it is unclear whether the selection of private concessionaires for PREPA's transmission and distribution system and legacy generation assets may have an impact on our business.

The PREB has instituted administrative proceedings regarding customer complaints about our Puerto Rican operations, the operations of some of our dealers in Puerto Rico and certain Sunnova policies and procedures related to contract disclosures and invoice disputes in Puerto Rico. At this time, we are unable to determine whether the PREB will seek penalties against us in the future in connection with these proceedings or require a change in our practices and procedures. Based on this matter, the U.S. Better Business Bureau listed Sunnova as not accredited. We have not experienced a material impact as a result of the listing.

***The ongoing COVID-19 pandemic and future pandemics could adversely affect our business, financial condition and results of operations.***

The ongoing COVID-19 pandemic has resulted in and may continue to result in widespread adverse impacts on the global economy. We have experienced some resulting disruptions to our business operations as the COVID-19 virus has continued to evolve and circulate through the states and U.S. territories in which we operate and foreign markets in which we may expand to in the future. We and our dealers modified certain business and workforce practices (including those related to new contract origination, installation and servicing of solar energy systems and employee work locations) to conform to government restrictions and best practices encouraged by governmental and regulatory authorities. Such modifications have allowed our dealers to continue to install and us to continue to service solar energy systems, but may also disrupt our operations, impede productivity or otherwise be ineffective in the future. Additionally, there are new and more frequent attempts by malicious third parties seeking to take advantage of our employees while working remotely to fraudulently gain access to our systems, which could cause us to expend significant resources to remediate and could damage our reputation. The complexity of resuming operations in our offices under a hybrid workplace model may adversely impact the productivity, health and well-being of our workforce and exacerbate security and execution risks that could cause us to lose the confidence of our customers and government agencies and harm our revenues and earnings. If there are additional outbreaks of the COVID-19 virus or other viruses or more stringent health and safety guidelines are adopted, our and our dealers' ability to continue performing installations and service calls may be adversely impacted. A significant or extended decline in new contract origination may have a material adverse effect on our business, cash flows, liquidity, financial condition and results of operations.

There is considerable uncertainty regarding the extent and duration of governmental and other measures implemented to try to slow the spread of the COVID-19 virus, such as large-scale travel bans and restrictions, border closures, quarantines, shelter-in-place orders and business and government shutdowns. Restrictions of this nature have caused, and may continue to cause, us and our dealers to experience operational delays and may cause milestones or deadlines related to our exclusivity arrangements to be missed. While many countries have lifted or will soon lift such measures, and the United States has announced it will lift such measures in May 2023, if there are additional outbreaks of the COVID-19 virus or other viruses, such measures may be implemented again. To date, we have not received notices from our dealers regarding performance delays resulting from the COVID-19 pandemic; however, we have seen delays in most jurisdictions from whom we must receive permission to operate for our solar energy systems to be placed in service. Worsening economic conditions could result in less favorable outcomes over time, which would impact our future financial performance. Finally, if supply chains become significantly disrupted due to additional outbreaks of the COVID-19 virus or other viruses or more stringent health and safety guidelines are implemented, our ability to install and service solar energy systems could become adversely impacted.

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

We cannot predict the full impact the COVID-19 pandemic or other pandemics or the significant disruption and volatility currently being experienced in the capital markets will have on our business, cash flows, liquidity, financial condition and results of operations at this time due to numerous uncertainties. The ultimate impact will depend on future developments, including, among other things, the ultimate duration of the COVID-19 virus, the distribution, acceptance and efficacy of the vaccine, the depth and duration of the economic downturn and other economic effects of the COVID-19 pandemic, the consequences of governmental and other measures designed to prevent the spread of the COVID-19 virus, actions taken by governmental authorities, customers, dealers and other third parties, our ability and the ability of our customers, potential customers and dealers to adapt to operating in a changed environment and the timing and extent to which normal economic and operating conditions resume.

***Dealer and marketplace confidence in our liquidity and long-term business prospects is important for building and maintaining our business.***

Our financial condition, operating results and business prospects may suffer materially if we are unable to establish and maintain confidence about our liquidity and business prospects among dealers, consumers and within our industry. Our dealer network is an integral component of our business strategy and serves as the means by which we are able to rapidly and successfully expand within existing and prospective markets. Dealers and other third parties will be less likely to enter into dealer agreements with us or originate new solar service agreements if they are uncertain we will be able to make payments on time, our business will succeed or our operations will continue for many years.

Our solar energy systems and energy storage systems require ongoing maintenance and support. If we were to reduce operations, even years from now, buyers of our solar energy systems and energy storage systems from years earlier might have difficulty having us provide or arrange repairs or other services to our and their solar energy systems and energy storage systems, which remain our responsibility under the terms of our solar service agreements. As a result, consumers may be less likely to enter into solar service agreements with us if they are uncertain our business will succeed or our operations will continue for many years.

Accordingly, in order to build and maintain our business, we must maintain confidence among dealers, customers and other parties in our liquidity and long-term business prospects. We may not succeed in our efforts to build this confidence.

***Damage to our brand and reputation or change or loss of use of our brand could harm our business and results of operations.***

We depend significantly on our reputation for high-quality products, excellent customer service and the brand name "Sunnova" to attract new customers and grow our business. If we fail to continue to deliver our solar energy systems or energy storage systems within the planned timelines, if our offerings do not perform as anticipated or if we damage any of our customers' properties or delay or cancel projects, our brand and reputation could be significantly impaired. Future technological improvements may allow us to offer lower prices or offer new technology to new customers; however, technical limitations in our current solar energy systems and energy storage systems may prevent us from offering such lower prices or new technology to our existing customers. The inability of our current customers to benefit from technological improvements could cause our existing customers to lower the value they perceive our existing products offer and impair our brand and reputation.

In addition, given the sheer number of interactions our personnel or dealers operating on our behalf have with customers and potential customers, it is inevitable that some customers' and potential customers' interactions with our company or dealers operating on our behalf will be perceived as less than satisfactory. This has led to instances of customer complaints, some of which have affected our digital footprint on rating websites and social media platforms. If we cannot manage our hiring and training processes to avoid or minimize these issues to the extent possible, our reputation may be harmed and our ability to attract new customers would suffer.

In addition, if we were to no longer use, lose the right to continue to use or if others use the "Sunnova" brand, we could lose recognition in the marketplace among customers, suppliers and dealers, which could affect our business, financial condition, results of operations and would require financial and other investment and management attention in new branding, which may not be as successful.

***Our operating results and our ability to grow may fluctuate from quarter to quarter and year to year, which could make our future performance difficult to predict and could cause our operating results for a particular period to fall below expectations.***

Our quarterly and annual operating results and our ability to grow are difficult to predict and may fluctuate significantly in the future. We have experienced seasonal and quarterly fluctuations in the past and expect to experience such fluctuations in the future. In addition to the other risks described in this "*Risk Factors*" section, the following factors could cause our operating results to fluctuate:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;expiration or initiation of any governmental rebates or incentives;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;significant fluctuations in customer demand for our solar energy services, solar energy systems and energy storage systems;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;our dealers' ability to complete installations in a timely manner;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;our and our dealers' ability to gain interconnection permission for an installed solar energy system from the relevant utility;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;the availability, terms and costs of suitable financing;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;the amount, timing of sales and potential decreases in value of SRECs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;our ability to continue to expand our operations and the amount and timing of expenditures related to this expansion;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures or capital-raising activities or commitments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;changes in our pricing policies or terms or those of our competitors, including centralized electric utilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;actual or anticipated developments in our competitors' businesses, technology or the competitive landscape; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;natural disasters or other weather or meteorological conditions.

For these or other reasons, the results of any prior quarterly or annual periods should not be relied upon as indications of our future performance.

***Inflation could result in decreased value from future contractual payments and higher expenses for labor and equipment, which, in turn, could adversely impact our reputation, business, financial condition, cash flows and results of operations.***

Any future increase in inflation may adversely affect our costs, including our dealers' cost of labor and equipment, and may result in a decrease in value in our future contractual payments. Many of our solar service agreements, which generally have a term ranging from 10 to 25 years, do not contain any pricing escalators. The pricing escalators we do have may not keep pace with inflation, which would result in the agreement yielding decreased value over time. These factors could adversely impact our reputation, business, financial condition, cash flows and results of operations.

***An increase in interest rates may result in a decrease in origination for our homebuilder channel and a reduction in principal prepayments by our customers.***

Origination for our homebuilder channel relies on the construction and sale of new homes by our homebuilder partners. Many customers of our homebuilder partners rely on mortgage loans from banks and other lenders to finance a substantial portion of the purchase price for their home. Increased mortgage interest rates may lead to lower demand for new homes and a reduced number of homes available for solar origination through our homebuilder channel. Additionally, increased interest rates may result in fewer secondary home sales, a reduction in the number of customers refinancing their mortgage and uncertainty about the economy. This could result in a material reduction in the amount of our customers making principal prepayments of their loans.

***Future expansions of our operations may subject us to additional risks.***

We may in the future expand into other industry verticals. There is no assurance that we will be able to successfully develop products and services that are valued for these new industries. Our investment of resources to develop products and services for the new industries we enter into may either be insufficient or result in expenses that are excessive as compared to the revenue that we may earn in launching such vertical.

Additionally, our experience is in the U.S. solar energy system industry and, therefore, we may not be adequately prepared for entry into a new industry vertical, should it occur. As we explore additional opportunities, we can make no assurance that we will be able to accurately forecast demand (or lack thereof) for our products or services or that new industries would be receptive to our products or services. Failure to predict demand or growth accurately in new industries could have a material adverse effect on our business.

Any future international operations may subject us to risks related to currency fluctuations. Foreign currencies periodically experience rapid and/or large fluctuations in value against the U.S. dollar. A weakened U.S. dollar could increase the cost of procurement of raw materials, by our suppliers, from foreign jurisdictions and operating expenses in foreign locations, which could have a material adverse effect on our business and results of operations. Our planned international expansion further subjects us to currency risk.

Since the price at which we originate solar energy systems from our dealers is generated in U.S. dollars, we are mostly insulated from currency fluctuations. However, since suppliers of our dealers often incur a significant amount of their costs by purchasing raw materials and generating operating expenses in foreign currencies, if the value of the U.S. dollar depreciates significantly or for a prolonged period of time against these other currencies, this may cause those suppliers to raise the prices they charge us and our dealers, which in turn could harm our business and results of operations. Although the value of the U.S. dollar has been high relative to other currencies in recent periods, there is no guarantee this trend will continue.

***If we are unsuccessful in developing and maintaining our proprietary technology, including our Catalyst software, our ability to attract and retain dealers and customers could be impaired, our competitive position and our ability to raise capital could be harmed and our results of operations and financial position could be harmed.***

Our future growth depends on our ability to continue to develop and maintain our proprietary technology that supports our solar service offerings, including our design and proposal software, Catalyst. In addition, we rely, and expect to continue to rely, on licensing agreements with certain third parties for aerial images that allow us to efficiently and effectively analyze a customer's rooftop for solar energy system specifications. In the event our current or future products require features that we have not developed or licensed, or we lose the benefit of an existing license, we will be required to develop or obtain such technology through purchase, license or other arrangements. If the required technology is not available on commercially reasonable terms, or at all, we may incur additional expenses in an effort to internally develop the required technology.

***We intend to expand our operations to include international activities, which will subject us to a number of risks.***

Our long-term strategic plans include international expansion, including expansion into jurisdictions that have characteristics similar to those in which we currently operate. Risks inherent to international operations include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;the inability to work successfully with dealers with local expertise to originate international solar service agreements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;multiple, conflicting and changing laws and regulations, including export and import laws and regulations, privacy and data protection laws, economic sanctions laws and regulations, tax laws and regulations, environmental regulations, labor laws and other government requirements, approvals, permits and licenses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;laws and legal systems less developed or less predictable than those in the U.S.;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;changes in general economic and political conditions in the jurisdictions where we operate, including changes in government incentives related to power generation and solar electricity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;political and economic instability, including wars, acts of terrorism, political unrest, boycotts, curtailments of trade and other business restrictions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;the negative effects of military conflicts, including the Russian invasion of Ukraine in February 2022, and any escalation or expansion of hostilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;difficulties and costs in recruiting and retaining individuals skilled in international business operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;international business practices may conflict with U.S. customs or legal requirements, including anti-bribery and corruption regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;financial risks, such as longer sales and payment cycles and greater difficulty collecting accounts receivable or executing self-help remedies, if necessary;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;deficient or unreliable records related to real property ownership;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;potentially lower margins due to a lower average income level;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;fluctuations in currency exchange rates relative to the U.S. dollar; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;the inability to obtain, maintain or enforce intellectual property rights, including inability to apply for or register material trademarks in foreign countries, which could make it easier for competitors to capture increased market position.

Doing business in foreign markets requires us to be able to respond to rapid changes in market, legal, political and conflict conditions in these countries. The success of our business will depend, in part, on our ability to succeed in differing legal, regulatory, economic, social and political environments. We may not be able to develop and implement policies and strategies that will be effective in each location where we do business.

***If our allowance for credit losses is not enough to cover actual credit losses from our customer notes receivable portfolio, our results of operations and financial condition could be negatively affected.***

We maintain an allowance for credit losses, which is a reserve that represents our best estimate of actual credit losses we may experience in our existing customer notes receivable portfolio. The level of the allowance reflects our continuing evaluation of factors including the financial asset type, customer credit rating, contractual term, vintage, volume and trends in delinquencies, nonaccruals, write-offs and present economic, political and regulatory conditions. The determination of the appropriate level of the allowance for credit losses inherently involves subjectivity in our modeling and requires us to make estimates of current credit risks and future trends, all of which may undergo material changes or vary from our historical experience. Deterioration in economic conditions affecting our customers, including the effects of rising inflation in the U.S., new information regarding existing loans and other factors, both within and outside of our control, may require an increase in the allowance for credit losses. Furthermore, if write-offs in future periods exceed the allowance for credit losses we will need to increase the allowance for credit losses in future periods. Any increases in the allowance for credit losses will result in an increase in net loss and could have a material adverse effect on our business, financial condition and results of operations.

We adopted Accounting Standards Update No. 2016-13, *Financial Instruments—Credit Losses*, in January 2020, which requires entities to use a forward-looking expected loss approach, referred to as the current expected credit loss ("CECL") methodology in place of the previously-used incurred loss model. In future periods, CECL may result in increased reserves during or in advance of an economic downturn. If we are required to materially increase our level of allowance for credit losses for any reason, such increase could have a material adverse effect on our business, financial condition and results of operations.

***Certain of our key operational metrics, including estimated gross contracted customer value, are based on various assumptions and estimates we make that cover an extended period of time. Actual experience may vary materially from these estimates and assumptions and therefore undue reliance should not be placed on these metrics.***

Our key operational metrics include a number of assumptions and estimates we make that cover an extended period of time (up to 35 years) and may not prove accurate. In calculating estimated gross contracted customer value, we estimate projected monthly customer payments over the remaining life of our solar service agreements, which typically range from 10 to 25 years in length with an opportunity for customers to renew for up to an additional 10 years, and from the future sale of related SRECs. These estimated future cash flows depend on various factors including but not limited to solar service agreement type, contracted rates, customer loss rates, expected sun hours and the projected production capacity of the solar equipment installed. Additionally, in calculating estimated gross contracted customer value we also estimate cash distributions to tax equity fund investors and operating, maintenance and administrative expenses associated with the solar service agreements, including expenses related to accounting, reporting, audit, insurance, maintenance and repairs over the remaining life of our solar service agreements.

Furthermore, in calculating estimated gross contracted customer value, we discount our future net cash flows at 6% based in part on industry practice and in part on the interest rate obtained on certain recent securitizations. This discount rate might not be the most appropriate discount rate based on interest rates in effect from time to time and industry or company-specific risks associated with these cash flows and the appropriate discount rate for these estimates may change in the future due to the level of inflation, rising interest rates, our cost of capital, customer default rates and consumer demand for solar energy systems, among other things. We also assume customer losses of 0% in calculating these metrics even though we expect to have some minimal level of customer losses over the life of our contracts. To illustrate the way in which actual results may change, we present sensitivities around the discount rate and the rate of customer losses, although these sensitivities may not capture the most appropriate discount rate or the rate of customer losses we will experience. For a discussion of estimated gross contracted customer value and the related discount rate and such sensitivities, see "*Management's Discussion and Analysis of Financial Condition and Results of Operations—Key Financial and Operational Metrics—Estimated Gross Contracted Customer Value*".

PricewaterhouseCoopers LLP has not audited, reviewed, examined, compiled nor applied agreed-upon procedures with respect to these operational metrics or their components. The estimates discussed above are based on a combination of assumptions that may prove to be inaccurate over time. Such inaccuracies could be material, particularly given the estimates relate to cash flows up to 35 years in the future.

**Risks Related to the Solar Industry**

***If sufficient additional demand for solar energy systems does not develop or takes longer to develop than we anticipate, our origination of solar service agreements may decrease.***

The distributed solar energy market is at a relatively early stage of development in comparison to fossil fuel-based electricity generation. If additional demand for distributed solar energy systems fails to develop sufficiently or takes longer to develop than we anticipate, we may be unable to originate additional solar service agreements and related solar energy systems and energy storage systems to grow our business. In addition, demand for solar energy systems and energy storage systems in our targeted markets may not develop to the extent we anticipate. As a result, we may be unsuccessful in broadening our customer base through origination of solar service agreements and related solar energy systems and energy storage systems within our current markets or in new markets we may enter.

Many factors may affect the demand for solar energy systems, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;availability, substance and magnitude of solar support programs including government targets, subsidies, incentives, renewable portfolio standards and net metering rules;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;the relative pricing of other conventional and non-renewable energy sources, such as natural gas, coal, oil and other fossil fuels, wind, utility-scale solar, nuclear, geothermal and biomass;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;performance, reliability and availability of energy generated by solar energy systems compared to conventional and other non-solar renewable energy sources;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;availability and performance of energy storage technology, the ability to implement such technology for use in conjunction with solar energy systems and the cost competitiveness such technology provides to customers as compared to costs for those customers reliant on the conventional electrical grid; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;general economic conditions and the levels of inflation and interest rates.

The solar energy industry is constantly evolving, which makes it difficult to evaluate our prospects. We cannot be certain if historical growth rates reflect future opportunities or whether growth anticipated by us will be realized. The failure of distributed solar energy to achieve, or its being significantly delayed in achieving, widespread adoption could have a material adverse effect on our business, financial condition and results of operations.

***A material reduction in the retail price of electricity charged by electric utilities or other retail electricity providers would harm our business, financial condition and results of operations.***

Decreases in the retail price of electricity from electric utilities or from other retail electric providers, including other renewable energy sources such as larger-scale solar energy systems, could make our offerings less economically attractive. The price of electricity from utilities could decrease as a result of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;the construction of a significant number of new power generation plants, whether generated by natural gas, nuclear power, coal or renewable energy;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;the construction of additional electric transmission and distribution lines;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;a reduction in the price of natural gas or other natural resources as a result of increased supply due to new drilling techniques or other technological developments, a relaxation of associated regulatory standards or broader economic or policy developments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;less demand for electricity due to energy conservation technologies and public initiatives to reduce electricity consumption or to recessionary economic conditions; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;development of competing energy technologies that provide less expensive energy.

A reduction in electric utilities' rates or changes to peak hour pricing policies or rate design (such as the adoption of a fixed or flat rate) could also make our offerings less competitive with the price of electricity from the electrical grid. If the cost of energy available from electric utilities or other providers were to decrease relative to solar energy generated from solar energy systems or if similar events impacting the economics of our offerings were to occur, we may have difficulty attracting new customers or existing customers may default or seek to terminate, cancel or otherwise avoid the obligations under their solar service agreements. For example, large utilities in California have started transitioning customers to time-of-use rates and also have adopted a shift in the peak period for time-of-use rates to later in the day. Unless grandfathered under a different rate, customers with solar energy systems are required to take service under time-of-use rates with the later peak period. Moving utility customers to time-of-use rates or the shift in the timing of peak rates for utility-generated electricity to include times of day when solar energy generation is less efficient or non-operable could also make our offerings less competitive. Time-of-use

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

rates could also result in higher costs for our customers whose electricity requirements are not fully met by our offerings during peak periods.

Additionally, the price of electricity from utilities may grow less quickly than the escalator feature in certain of our solar service agreements, which could also make our solar energy systems less competitive with the price of electricity from the electrical grid and result in a material adverse effect on our business, financial condition and results of operations.

***Our business has benefited from the declining cost of solar energy system and energy storage system components and may be harmed to the extent the cost of such components stabilize or increase in the future.***

Our business has benefited from the declining cost of solar energy system and energy storage system components and to the extent such costs stabilize, decline at a slower rate or increase, our future growth rate may be negatively impacted. The declining cost of solar energy system and energy storage system components and the raw materials necessary to manufacture them has been a key driver in the price of solar energy systems and energy storage systems we own, the prices charged for electricity and customer adoption of solar energy. While historically solar energy system and energy storage system components and raw material prices have declined, the cost of these components and raw materials have recently increased and may continue to increase in the future, and such products' availability could decrease, due to a variety of factors, including growth in the solar energy system and energy storage system industries and the resulting increase in demand for solar energy system and energy storage system components and the raw materials necessary to manufacture them, supply chain disruptions, tariff penalties, duties, and trade barriers, export regulations, regulatory or contractual limitations, industry market requirements and industry standards, changes in technology, the loss of or changes in economic governmental incentives, inflation or other factors. An increase of solar energy system components and raw materials prices could slow our growth and cause our business and results of operations to suffer. See "*—Increases in the cost or reduction in supply of solar energy system and energy storage system components due to tariffs or trade restrictions imposed by the U.S. government could have an adverse effect on our business, financial condition and results of operations*".

***We and our dealers depend on a limited number of suppliers of solar energy system components and technologies to adequately meet demand for our solar energy systems. Due to the limited number of suppliers in our industry, the acquisition of any of these suppliers by a competitor or any shortage, delay, price change, imposition of tariffs or duties or other limitation in our or our dealers' ability to obtain components or technologies we use could result in sales and installation delays, cancelations and loss of customers.***

We rely on our dealers to install solar energy systems and energy storage systems, each of whom has direct supplier arrangements. Our dealers purchase solar panels, inverters, energy storage systems and other system components and instruments from a limited number of suppliers, approved by us, making us susceptible to quality issues, shortages and price changes. For the year ended December 31, 2022, Hanwha Q-Cells supplied approximately 68% of our solar photovoltaic panels installed and no other supplier represented more than 10% of our solar photovoltaic panels installed. For the year ended December 31, 2021, Hanwha Q-Cells, Longi Solar and REC Solar supplied approximately 52%, 16% and 10%, respectively, of our solar photovoltaic panels installed and no other supplier represented more than 10% of our solar photovoltaic panels installed. For the year ended December 31, 2022, Enphase Energy, Inc. and SolarEdge Technologies Inc. accounted for approximately 57% and 42%, respectively, of the inverters used in our solar energy system installations. For the year ended December 31, 2021, Enphase Energy, Inc. and SolarEdge Technologies Inc. accounted for approximately 64% and 34%, respectively, of the inverters used in our solar energy system installations. For the year ended December 31, 2022, Tesla, Inc. accounted for approximately 94% of our energy storage system purchases. For the year ended December 31, 2021, Tesla, Inc. and Enphase Energy Inc. accounted for approximately 80% and 14%, respectively, of our energy storage system purchases. There are a limited number of suppliers of solar energy system components, instruments and technologies. If one or more of the suppliers we and our dealers rely upon to meet anticipated demand ceases or reduces production due to its financial condition, acquisition by a competitor or otherwise, is unable to increase production as industry demand increases or is otherwise unable to allocate sufficient production to us and our dealers, it may be difficult to quickly identify alternative suppliers or to qualify alternative products on commercially reasonable terms and our ability and the ability of our dealers to satisfy this demand may be adversely affected. While we believe there are other sources of supply for these products available, a dealer's need to transition to a new supplier may result in additional costs and delays in originating solar service agreements and deploying our related solar energy systems or energy storage systems, which in turn may result in additional costs and delays in our acquisition of such solar service agreements and related solar energy systems and energy storage systems. These issues could have a material adverse effect on our business, financial condition and results of operations.

There have also been periods of industry-wide shortages of key components and instruments, including batteries and inverters, in times of rapid industry growth. The manufacturing infrastructure for some of these components has a long lead-time, requires significant capital investment and relies on the continued availability of key commodity materials, potentially

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

resulting in an inability to meet demand for these components. The solar industry is currently experiencing rapid growth and, as a result, shortages of key components or instruments, including solar panels, may be more likely to occur, which in turn may result in price increases for such components. Even if industry-wide shortages do not occur, suppliers may decide to allocate key components or instruments with high demand or insufficient production capacity to more profitable customers, customers with long-term supply agreements or customers other than us, our dealers or other third parties from whom we may originate solar energy systems and our ability to originate solar service agreements and related solar energy systems and energy storage systems may be reduced as a result.

Our supply chain and operations (or those of our dealers) could be subject to natural disasters and other events beyond our control, such as earthquakes, wildfires, flooding, hurricanes, freezes, tsunamis, typhoons, volcanic eruptions, droughts, tornadoes, power outages or other natural disasters, the effects of climate change and related extreme weather, public health issues and pandemics, war, terrorism, government restrictions or limitations on trade, impediments to international shipping and geopolitical unrest and uncertainties. Human rights and forced labor issues in foreign countries and the U.S. government's response to them could disrupt our supply chain and our operations could be adversely impacted.

Historically, we and our dealers have relied on foreign suppliers for a number of solar energy system components, instruments and technologies that our dealers purchase. Our success in the future may be dependent on our dealers' ability to import or transport such products from overseas vendors in a timely and cost-effective manner. We and our dealers may rely heavily on third parties, including ocean carriers and truckers, both of which are experiencing disruptions, shortages and rate increases, in that process.

The global shipping industry has experienced and may continue to experience ocean shipping disruptions, trucking shortages, increased ocean shipping rates and increased trucking and fuel costs. There has been and may in the future be a shortage of shipping capacity from China and other parts of Asia, and as a result, our dealers' receipt of imported products may be disrupted or delayed. The shipping industry has also experienced issues with port congestion and pandemic-related port closures and ship diversions. Disruptions related to the global COVID-19 pandemic may continue to affect trans-Pacific shipping from China. The global shipping industry also experienced unprecedented increases in shipping rates from the trans-Pacific ocean carriers due to various factors, including limited availability of shipping capacity. Our dealers may find it necessary to rely on an increasingly expensive spot market and other alternative sources to make up any shortfall in shipping needs.

If our dealers cannot obtain substitute materials or components on a timely basis or on acceptable terms, they could be prevented from installing our solar energy systems within the time frames required in our customer contracts. Any such delays could increase our overall costs, reduce our profit, delay the timing for solar energy systems to be placed in service and ultimately have a material adverse effect on our business, financial condition and results of operations.

Additionally, if the impacts of the COVID-19 pandemic continue for an extended period of time or worsen, the supply and pricing of our inverters and other goods and therefore the ability of our dealers to install new solar energy systems could be adversely affected. The extent of the impact of the COVID-19 pandemic on our business and operations will depend on, among other factors, the duration and severity of the outbreak, travel restrictions and business closures imposed in China or other countries and their ability to recover from such restrictions when they are lifted, the ability of our suppliers to increase their production of goods in jurisdictions other than China, our ability to contract for supply from other sources on acceptable terms and the willingness of our lenders to permit us to switch suppliers.

***Warranties provided by the manufacturers of equipment for our assets and maintenance obligations of our dealers may be limited by the ability of a supplier and/or dealer to satisfy its warranty or performance obligations or by the expiration of applicable time or liability limits, which could reduce or void the warranty protections or may be limited in scope or magnitude of liabilities and thus, the warranties and maintenance obligations may be inadequate to protect us.***

We agree to maintain the solar energy systems and energy storage systems installed on our customers' homes and businesses during the length of the term of our solar service agreements, which typically range from 10 to 25 years. We are exposed to any liabilities arising from the solar energy systems' failure to operate properly and are generally under an obligation to ensure each solar energy system remains in good condition during the term of the agreement. We are the beneficiary of the panel manufacturers' warranty coverage, typically of 10 years for material and workmanship and 25 years for performance, the inverter manufacturers' warranty coverage, typically from 10 to 25 years and the energy storage manufacturers' warranty coverage, typically of 10 years. Furthermore, our dealers provide warranties as to their workmanship. In the event such warranty providers or dealers file for bankruptcy, cease operations or otherwise become unable or unwilling to fulfill their warranty or maintenance obligations, we may not be adequately protected by such warranties or maintenance obligations. Even if such warranty or maintenance providers or dealers fulfill their obligations, the warranty or maintenance obligations may not

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

be sufficient to protect us against all of our losses. In addition, our warranties are of limited duration, ranging from one year, in the case of certain solar energy system and transformer warranties, to 25 years, in the case of certain panel performance warranties, after the date each equipment item is delivered or commissioned, although the useful life of our solar energy systems is 35 years. These warranties are subject to liability and other limits. If we seek warranty protection and a warranty provider is unable or unwilling to perform its warranty obligations, or if a dealer is unable or unwilling to perform its maintenance obligations, whether as a result of its financial condition or otherwise, or if the term of the warranty or maintenance obligation has expired or a liability limit has been reached, there may be a reduction or loss of protection for the affected assets, which could have a material adverse effect on our business, financial condition and results of operations.

Our failure to accurately predict future liabilities related to material quality or performance expenses could result in unexpected volatility in our financial condition. Because of the long estimated useful life of our solar energy systems, we have been required to make assumptions and apply judgments regarding a number of factors, including our anticipated rate of warranty claims and the durability, performance and reliability of our solar energy systems. We made these assumptions based on the historic performance of similar solar energy systems or on accelerated life cycle testing. Our assumptions could prove to be materially different from the actual performance of our solar energy systems, causing us to incur substantial expense to repair or replace defective solar energy systems in the future or to compensate customers for solar energy systems that do not meet their performance guarantees. Equipment defects, serial defects or operational deficiencies also would reduce our revenue from solar service agreements because the customer payments under such agreements are dependent on solar energy system production or would require us to make refunds under performance guarantees. Any widespread product failures or operating deficiencies may damage our market reputation and adversely impact our financial results. For further discussion of these potential charges and related proposals, see "*Management's Discussion and Analysis of Financial Condition and Results of Operations—Components of Results of Operations*".

***Increases in the cost or reduction in supply of solar energy system and energy storage system components due to tariffs or trade restrictions imposed by the U.S. government could have an adverse effect on our business, financial condition and results of operations.***

China is a major producer of solar cells and other solar products. Certain solar cells, modules, laminates and panels from China are subject to various U.S. antidumping and countervailing duty rates, depending on the exporter supplying the product, imposed by the U.S. government as a result of determinations that the U.S. was materially injured as a result of such imports being sold at less than fair value and subsidized by the Chinese government. While historically our dealers have endeavored to purchase these products from manufacturers outside of China, some of these products are purchased from manufacturers in China or from manufacturers in other jurisdictions who rely, in part, on products sourced in China. If alternative sources are no longer available on competitive terms in the future, we and our dealers may be required to purchase these products from manufacturers in China. In addition, tariffs on solar cells, modules and inverters in China may put upward pressure on prices of these products in other jurisdictions from which our dealers currently purchase equipment, which could reduce our ability to offer competitive pricing to potential customers.

The antidumping and countervailing duties discussed above are subject to annual review and may be increased or decreased. Furthermore, under Section 301 of the Trade Act of 1974, the USTR imposed tariffs on $200 billion worth of imports from China, including inverters and certain AC modules and non-lithium-ion batteries, effective September 24, 2018. In May 2019, the tariffs were increased from 10% to 25% and may be raised by the USTR in the future. Since these tariffs impact the purchase price of the solar products, these tariffs raise the cost associated with purchasing these solar products from China and reduce the competitive pressure on providers of solar cells not subject to these tariffs.

In August 2021, an anonymous trade group filed a petition with the U.S. Department of Commerce requesting an investigation into whether solar panels and cells imported from Malaysia, Thailand and Vietnam are circumventing anti-dumping and countervailing duties imposed on solar products manufactured in China. The group also requested the imposition of tariffs on such imports ranging from 50% - 250%. In November 2021, the U.S. Department of Commerce rejected the petition, citing the petitioners' ongoing anonymity as one of the reasons for its decision. In March 2022, the U.S. Department of Commerce announced it is initiating country-wide circumvention inquiries to determine whether imports of solar cell and modules produced in Cambodia, Malaysia, Thailand and Vietnam that use components from China are circumventing anti-dumping and countervailing duty orders on solar cells and modules from China. The Department of Commerce's inquiries were initiated pursuant to a petition filed by Auxin Solar, Inc. on February 8, 2022.

While the investigation remains ongoing, in December 2022, the Department of Commerce announced its preliminary determination in the investigation. In its determination, the Department of Commerce found that certain Chinese solar manufacturers circumvented U.S. import duties by routing some of their operations through Cambodia, Malaysia, Thailand and Vietnam. Given the Department of Commerce preliminarily found that circumvention was occurring through each of the four

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

Southeast Asian countries, the Department of Commerce made a "country-wide" circumvention finding, which designates each country as one through which solar cells and modules are being circumvented from China. However, companies in these countries will be permitted to certify they are not circumventing the U.S. import duties, in which case the circumvention findings may not apply. The Department of Commerce will take a number of additional steps before issuing a final determination. In particular, the Department of Commerce will conduct in-person audits to verify the information that was the basis of its preliminary determination. Furthermore, the Department of Commerce will gather public comments on the preliminary determination to consider before issuing its final determination, which is currently scheduled for May 1, 2023.

Notably, however, on June 6, 2022, the President of the United States issued an emergency declaration establishing a tariff exemption of two years for solar panels and cells imported from Cambodia, Malaysia, Thailand and Vietnam, delaying the possibility of the imposition of dumping duties until the end of such two-year period. In September 2022, the Department of Commerce issued its final rule effectuating the two-year exemption period, and new dumping duties will not be imposed on solar panels and cells imported from Cambodia, Malaysia, Thailand and Vietnam until the earlier of two years after the date of the emergency declaration or when the emergency is terminated. Tariffs may be reinstated following the exemption period, but imports of solar cells and modules will not be subject to retroactive tariffs during the exemption period. The addition of new dumping duties would significantly disrupt the supply of solar cells and modules to customers in the U.S., as a large percentage of solar cells and modules used in the U.S. are imported from Cambodia, Malaysia, Thailand and Vietnam. If imposed, these or similar tariffs could put upward pressure on prices of these solar products, which could reduce our ability to offer competitive pricing to potential customers.

In addition, in December 2021, the U.S. International Trade Commission recommended the President extend tariffs initially imposed in 2018 on imported crystalline silicon PV cells and modules for another four years, until 2026. Under Presidential Proclamation 10339, published in February 2022, President Biden extended the tariff beyond the scheduled expiration date of February 6, 2022, with an initial tariff of 14.75%, which will gradually be reduced to 14% by the eighth year of the measure. Since such actions increase the cost of imported solar products, to the extent we or our dealers use imported solar products or domestic producers are able to raise their prices for their solar products, the overall cost of the solar energy systems will increase, which could inhibit our ability to offer competitive pricing in certain markets.

Additionally, the U.S. government has imposed various trade restrictions on Chinese entities determined to be acting contrary to U.S. foreign policy and national security interests. For example, the U.S. Department of Commerce's Bureau of Industry and Security has added a number of Chinese entities to its entity list for enabling human rights abuses in the Xinjiang Uyghur Autonomous Region ("XUAR") or for procuring U.S. technology to advance China's military modernization efforts, thereby imposing severe trade restrictions against these designated entities. Moreover, in June 2021, U.S. Customs and Border Protection issued a Withhold Release Order pursuant to Section 307 of the Tariff Act of 1930 excluding the entry into U.S. commerce silica-based products (such as polysilicon) manufactured by Hoshine Silicon Industry Co. Ltd. ("Hoshine") and related companies, as well as goods made using those products, based on allegations related to Hoshine labor practices in the XUAR to manufacture such products. Additionally, in December 2021, Congress passed the Uyghur Forced Labor Prevention Act, which, with limited exception, prohibits the importation of all goods or articles mined or produced in whole or in part in the XUAR, or goods or articles mined or produced by entities working with the XUAR government to recruit, transport or receive forced labor from the XUAR. Although we maintain policies and procedures designed to maintain compliance with all governmental laws and regulations, these and other similar trade restrictions that may be imposed against Chinese entities in the future may have the effect of restricting the global supply of, and raising prices for, polysilicon and solar products, which could increase the overall cost of solar energy systems and reduce our ability to offer competitive pricing in certain markets.

We cannot predict what additional actions the U.S. may adopt with respect to tariffs or other trade regulations or what actions may be taken by other countries in retaliation for such measures. The tariffs described above, the adoption and expansion of trade restrictions, the occurrence of a trade war or other governmental action related to tariffs, trade agreements or related policies have the potential to adversely impact our supply chain and access to equipment, our costs and ability to economically serve certain markets. If additional measures are imposed or other negotiated outcomes occur, our ability or the ability of our dealers to purchase these products on competitive terms or to access specialized technologies from other countries could be further limited, which could adversely affect our business, financial condition and results of operations.

***The solar energy systems we own or may originate have a limited operating history and may not perform as we expect.***

Many of the solar energy systems we currently own or may originate in the future have not commenced operations, have recently commenced operations or otherwise have a limited operating history. Of the approximately 146,000 solar energy systems we owned as of December 31, 2022, 22%, 18% and 14% were placed into service in 2022, 2021 and 2020, respectively. The ability of our solar energy systems to perform as we expect will also be subject to risks inherent in newly constructed renewable energy assets, including breakdowns and outages, latent defects, equipment that performs below our

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

expectations, system failures and outages. As a result, our assumptions and estimates regarding the performance of these solar energy systems are, and will be, made without the benefit of a meaningful operating history, which may impair our ability to accurately assess the potential profitability of the solar energy systems and, in turn, our results of operations, financial condition and cash flows.

***The cost of maintenance or repair of solar energy systems or energy storage systems throughout the term of the associated solar service agreement or the removal of solar energy systems at the end of the term of the associated solar service agreement may be higher than projected today and adversely affect our financial performance and valuation.***

If we incur repair and maintenance costs on our solar energy systems or energy storage systems after the individual component warranties have expired and if they then fail or malfunction, we will be liable for the expense of repairing these solar energy systems or energy storage systems without a chance of recovery from our suppliers. In addition, we typically bear the cost of removing the solar energy systems at the end of the term of the lease or PPA if the customer does not renew his or her agreement or elect to purchase the solar energy system at the end of its term. Furthermore, it is difficult to predict how future environmental regulations may affect the costs associated with the repair, removal, disposal or recycling of our solar energy systems. This could materially impair our future operating results.

***Problems with performance of our solar energy systems may cause us to incur expenses, may lower the value of our solar energy systems and may damage our market reputation and adversely affect our business.***

In most cases, our long-term leases and loan agreements contain a performance guarantee in favor of the customer. Solar service agreements with performance guarantees require us to provide a bill credit (or in limited cases, refund money) to the customer if the solar energy system fails to generate the minimum amount of electricity, as specified in the solar service agreement, in a given term, beginning as early as the first anniversary of the execution of the solar service agreement and annually thereafter. We may also suffer financial losses associated with such credit and refunds if significant performance guarantee payments are triggered. For a description of our performance guarantee obligations, see "*Management's Discussion and Analysis of Financial Condition and Results of Operations—Components of Results of Operations—Revenue*".

***We and our dealers are subject to risks associated with installation and other contingencies.***

Our dealers design and install solar energy systems and energy storage systems on our behalf. Because the solar service agreement is entered into between us and the customer, we may be liable to our customers for any damage our dealers cause to our customers' homes or businesses, belongings or property during the installation of our solar energy systems and energy storage systems or otherwise.

For example, dealers may penetrate our customers' roofs during the installation process and we may incur liability for the failure to adequately weatherproof such penetrations following the completion of installation of solar energy systems. In addition, because our solar energy systems and energy storage systems are high-voltage energy systems, we may incur liability for a dealer's failure to comply with electrical standards and manufacturer recommendations. Furthermore, prior to obtaining permission to operate our solar energy systems and energy storage systems, the solar energy systems and energy storage systems must pass various inspections. Any delay in passing, or inability to pass, such inspections, would adversely affect our results of operations. Because our profit on a particular solar service agreement and related solar energy system and energy storage system, if applicable, is based in part on assumptions as to the ongoing cost of the related solar energy system and energy storage system, if applicable, cost overruns, delays or other execution issues may cause us to not achieve our expected results or cover our costs for that solar service agreement and related solar energy system and energy storage systems, if applicable.

***Product liability claims against us or accidents could result in adverse publicity and potentially significant monetary damages.***

It is possible our solar energy systems, energy storage systems or our other current or anticipated products could injure our customers or other third parties or those systems or products could cause property damage as a result of product malfunctions, defects, improper installation, fire or other causes. We rely on third-party manufacturing warranties, warranties provided by our dealers and our general liability insurance to cover product liability claims and have not obtained separate product liability insurance. Our solar energy systems, energy storage systems and other products or their components could be subject to recalls either to production defects or malfunctions. Any product liability claim we face could be expensive to defend and may divert management's attention. The successful assertion of product liability claims against us could result in potentially significant monetary damages, potential increases in insurance expenses, penalties or fines, subject us to adverse publicity, damage our reputation and competitive position and adversely affect sales of solar energy systems or energy storage systems. In addition,

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

product liability claims, injuries, defects or other problems experienced by other companies in the solar industry could lead to unfavorable market conditions to the industry as a whole and may have an adverse effect on our ability to expand our portfolio of solar service agreements and related solar energy systems and energy storage systems, thus affecting our business, financial condition and results of operations.

***We typically bear the risk of loss and the cost of maintenance, repair and removal on solar energy systems that are owned by our subsidiaries and included in securitization and tax equity vehicles.***

We typically bear the risk of loss and are generally obligated to cover the cost of maintenance, repair and removal for any solar energy system we sell to subsidiaries and include in securitization and tax equity vehicles. At the time we enter into a tax equity or securitization transaction, we enter into a maintenance services agreement where we agree to operate and maintain the solar energy system for a fixed fee calculated to cover our future expected maintenance costs. If our solar energy systems require an above-average amount of repairs or if the cost of repairing the solar energy systems were higher than our estimate, we would need to perform such repairs without additional compensation. If our solar energy systems, approximately 48% of which were located in California and Puerto Rico as of December 31, 2022, are damaged as the result of a natural disaster beyond our control, losses could exceed or be excluded from our insurance policy limits and we could incur unforeseen costs that could harm our business and financial condition. We may also incur significant costs for taking other actions in preparation for, or in reaction to, such events. We purchase property insurance with industry standard coverage and limits approved by an investor's third-party insurance advisors to hedge against such risk, but such coverage may not cover our losses.

***The installation and operation of solar energy systems and energy storage systems depends heavily on suitable solar and meteorological conditions, which may be impacted by the effects of climate change. If meteorological conditions are unexpectedly unfavorable, the electricity production from our solar energy systems may be substantially below our expectations and our ability to timely deploy new solar energy systems and energy storage systems may be adversely impacted.***

The energy produced and the revenue and cash receipts generated by a solar energy system depend on suitable solar, atmospheric and weather conditions, all of which are beyond our control. Furthermore, components of our systems, such as panels and inverters, could be damaged by severe weather or natural catastrophes, such as hurricanes, freezes, hailstorms, tornadoes, fires or earthquakes. Our economic model and projected returns on our solar energy systems require achievement of certain production results from our systems and, in some cases, we guarantee these results to our consumers. If the solar energy systems underperform for any reason, our business could suffer. For example, the amount of revenue we recognize in a given period from our PPAs and the amount of our obligations under the performance guarantees of our solar service agreements are dependent in part on the amount of energy generated by solar energy systems under such solar service agreements. As a result, revenue derived from our standard PPAs is impacted by seasonally shorter daylight hours in winter months. In addition, the ability of our dealers to install solar energy systems and energy storage systems is impacted by weather. For example, the ability to install solar energy systems and energy storage systems during the winter months in the Northeastern U.S. is limited. Such solar, atmospheric and weather conditions can delay the timing of when solar energy systems and energy storage systems can be installed and when we can originate and begin to generate revenue from solar energy systems. This may increase our expenses and decrease revenue and cash receipts in the relevant periods. These or other effects could make our solar energy systems less economical overall or make individual solar energy systems less economical. Any of these effects on meteorological conditions could harm our business, financial condition and results of operations.

***Climate change may have long-term impacts on our business, our industry and the global economy.***

Climate change poses a systemic threat to the global economy and is inextricably linked with our business. While our core business model seeks to mitigate climate change and accelerate energy independence, there are inherent climate-related risks to our business operations. Climate change could exacerbate the frequency and severity of weather events in all areas where we operate. Climate change or other factors could also cause prevailing weather patterns to materially change in the future, making it harder to predict the average annual amount of sunlight striking each location where we install a solar energy system and energy storage system. Potential negative effects of climate change include, among others, a temporary decrease in solar availability in certain locations, disruptions in transmission grids and delays or reductions in new installations. These or other effects could make our solar energy systems less economical overall or make individual solar energy systems less economical. Any of these effects on meteorological conditions could harm our business, financial condition and results of operations.

***We may be subject to interruptions or failures in our information technology systems.***

We rely on information technology systems and infrastructure to support our business. Any of these systems may be susceptible to damage or interruption due to fire, floods, power loss, telecommunication failures, usage errors by employees,

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

computer viruses, cyberattacks or other security breaches or similar events. For example, we have in the past experienced cybersecurity attacks on our information technology systems or related to software we utilize, and, while none to date have been material, we expect further attacks may occur in the future, some of which may be material. A compromise of our information technology systems or those with which we interact could harm our reputation and expose us to regulatory actions and claims from customers and other persons, any of which could adversely affect our business, financial condition, cash flows and results of operations. If our information systems are damaged, fail to work properly or otherwise become unavailable, we may incur substantial costs to repair or replace them and we may experience a loss of critical information, customer disruption and interruptions or delays in our ability to perform essential functions.

***Disruptions to our solar monitoring systems could negatively impact our revenues and increase our expenses.***

Our ability to accurately charge our customers for the energy produced by our solar energy systems primarily depends on the cellular connection for the related monitoring system, which we are responsible for maintaining in a functional state so we may receive data regarding the solar energy systems' production from their residences and businesses. We could incur significant expenses or disruptions of our operations in connection with failures of our solar monitoring systems, including failures of such connections, that would prevent us from accurately monitoring solar energy production. In addition, sophisticated hardware and operating system software and applications we procure from third parties may contain defects in design or manufacture, including "bugs" and other problems that could unexpectedly interfere with the operation of our solar energy systems or energy storage systems. The costs to us to eliminate or alleviate viruses and bugs, or any problems associated with failures of our cellular connections could be significant. We have in the past experienced periods where some of our cellular connections have been unavailable and, as a result, we have been forced to estimate the production of their solar energy systems. Such estimates may prove inaccurate and could cause us to underestimate the power being generated by our solar energy systems and undercharge our customers, thereby harming our results of operations.

***Any unauthorized access to or disclosure or theft of personal information we gather, store or use could harm our reputation and subject us to claims or litigation.***

We receive, store and use personal information of our customers, including names, addresses, e-mail addresses, credit information, credit card and financial account information and other housing or building and energy use information. We also store information of our dealers, including employee, financial and operational information. We rely on the availability of data collected from our customers and our dealers in order to manage our business and market our offerings. We take certain steps in an effort to protect the security, integrity and confidentiality of the personal information we collect, store or transmit, but there is no guarantee inadvertent or unauthorized use or disclosure will not occur or third parties will not gain unauthorized access to this information despite our efforts. We also rely on third-party suppliers or vendors to host certain of the systems we use. Although we take precautions to provide for disaster recovery, our ability to recover systems or data may be expensive and may interfere with our normal operations. Also, although we obtain assurances from such third parties they will use reasonable safeguards to secure their systems, we may be adversely affected by unavailability of their systems or unauthorized use or disclosure or our data maintained in such systems. Because techniques used to obtain unauthorized access or sabotage systems change frequently and generally are not identified until they are launched against a target, we, our suppliers or vendors and our dealers may be unable to anticipate these techniques or to implement adequate preventative or mitigation measures.

Cyberattacks in particular are becoming more sophisticated and include, but are not limited to, malicious software, attempts to gain unauthorized access to data and other electronic security breaches that could lead to disruptions in critical systems, disruption of our customers' operations, loss or damage to our data delivery systems, unauthorized release of confidential or otherwise protected information, corruption of data and increased costs to prevent, respond to or mitigate cybersecurity events. In addition, certain cyber incidents, such as advanced persistent threats, may remain undetected for an extended period.

Unauthorized use, disclosure of or access to any personal information maintained by us or on our behalf, whether through breach of our systems, breach of the systems of our suppliers, vendors or dealers by an unauthorized party or through employee or contractor error, theft or misuse or otherwise, could harm our business. If any such unauthorized use, disclosure of or access to such personal information were to occur, our operations could be seriously disrupted and we could be subject to demands, claims and litigation by private parties and investigations, related actions and penalties by regulatory authorities.

In addition, we could incur significant costs in notifying affected persons and entities and otherwise complying with the multitude of federal, state and local laws and regulations related to the unauthorized access to, use of or disclosure of personal information. Finally, any perceived or actual unauthorized access to, use of or disclosure of such information could harm our reputation, substantially impair our ability to expand our portfolio of solar service agreements and related solar energy systems and energy storage systems and have an adverse impact on our business, financial condition and results of operations. The COVID-19 pandemic generally is increasing the attack surface available to criminals, as more companies and individuals work

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

remotely and otherwise work online. Consequently, the risk of a cybersecurity incident suffered by us or our vendors or service providers is increased, and our investment in risk mitigations against cybersecurity incidents is evolving as the threat landscape changes. While we currently maintain cybersecurity insurance, such insurance may not be sufficient to cover us against claims, and we cannot be certain that cyber insurance will continue to be available to us on economically reasonable terms, or at all, or that any insurer will not deny coverage as to any future claim.

***Terrorist or cyberattacks against centralized utilities could adversely affect our business.***

Assets owned by utilities such as substations and related infrastructure have been physically attacked in the past and will likely be attacked in the future. These facilities are often protected by limited security measures, such as perimeter fencing. Any such attacks may result in interruption to electricity flowing on the grid and consequently interrupt service to our solar energy systems not combined with an energy storage system, which could adversely affect our operations. Furthermore, cyberattacks, whether by individuals or nation states, against utility companies could severely disrupt their business operations and result in loss of service to customers, which would adversely affect our operations.

***Disruptions to our solar production metering and energy storage control solution could negatively impact our revenue and increase our expenses.***

Our ability to monitor solar energy production, energy storage and battery discharge for various purposes depends on the operation of our metering solution and energy storage control. We could incur significant expense and disruption to our operations in connection with failures of our metering solution and energy storage control, including meter hardware failures, energy storage monitoring and control hardware failures and failure or obsolescence of the cellular and other technology that we use to communicate with those meters and controls. For example, many of our meters operate on either the 3G or 4G cellular data networks, which are expected to sunset before the term of our customer agreements, and newer technologies we use today may become obsolete before the end of the term of customer agreements entered into now. Upgrading our metering solution may cause us to incur significant expense. Hardware may also be damaged or these systems may fail to communicate due to equipment failure, manufacturing defects, natural disasters such as hurricanes, freezes, fires and earthquakes, terrorist attacks, sabotage, vandalism and environmental risks. Additionally, our meters communicate data through proprietary software, which we license from our metering partners. Should we be unable to continue to license, on agreeable terms, the software necessary to communicate with our meters, it could cause a significant disruption in our business and operations.

***We face competition from centralized electric utilities, retail electric providers, independent power producers and renewable energy companies.***

The solar energy and renewable energy industries are both highly competitive and continually evolving as participants strive to distinguish themselves within their markets and compete with large centralized electric utilities. We believe our primary competitors are the centralized electric utilities that supply electricity to our potential customers. We compete with these centralized electric utilities primarily based on price (cents per kWh), predictability of future prices (by providing pre-determined annual price escalations) and the ease by which customers can switch to electricity generated by our solar energy systems. We may also compete based on other value-added benefits, such as reliability and carbon-friendly power. If we cannot offer compelling value to our customers based on these factors, our business may not grow.

Centralized electric utilities generally have substantially greater financial, technical, operational and other resources than we do. As a result, these competitors may be able to devote more resources to the research, development, promotion and sale of their products or services or respond more quickly to evolving industry standards and changes in market conditions than we can. Centralized electric utilities could also offer other value-added products or services that could help them to compete with us even if the cost of electricity they offer is higher than ours. In addition, a majority of utilities' sources of electricity is non-solar, which may allow utilities to sell electricity more cheaply than electricity generated by our solar energy systems. Centralized electric utilities could also offer customers the option of purchasing electricity obtained from renewable energy resources, including solar, which would compete with our offerings. Moreover, regulated utilities are increasingly seeking approval to "rate-base" their own solar energy system and energy storage system businesses. Rate-basing means that utilities would receive guaranteed rates of return for their solar energy system and energy storage system businesses. This is already commonplace for utility-scale solar projects and commercial solar projects. While few utilities to date have received regulatory permission to rate-base residential solar energy systems or energy storage systems, our competitiveness would be significantly harmed should more utilities receive such permission because we do not receive guaranteed profits for our solar service offerings.

We also compete with retail electric providers and independent power producers not regulated like centralized electric utilities but which have access to the centralized utilities' electricity transmission and distribution infrastructure pursuant to

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

state, territorial and local pro-competition and consumer choice policies. These retail electric providers and independent power producers are able to offer customers electricity supply-only solutions that are competitive with our solar energy system options on both price and usage of renewable energy technology while avoiding the long-term agreements and physical installations our current business model requires. This may limit our ability to acquire new customers, particularly those who wish to avoid long-term agreements or have an aesthetic or other objection to putting solar panels on their roofs.

We also compete with solar companies with vertically integrated business models, including sales, financing, engineering, manufacturing, installation, maintenance and monitoring services. If the integrated approach of our competitors is successful, it may limit our ability to originate solar energy systems. Many of our vertically integrated competitors are larger than we are. As a result, these competitors may be able to devote more resources to the research, development, promotion and sale of their products or services or respond more quickly to evolving industry standards and changes in market conditions than we can. Solar companies with vertically integrated business models could also offer other value-added products or services that could help them to compete with us. Larger competitors may also be able to access financing at a lower cost of capital than we are able to obtain.

In addition, we compete with other solar companies who sell or finance products directly to consumers, inclusive of programs like Property-Assessed Clean Energy financing programs established by local governments. For example, we face competition from solar installation businesses that seek financing from external parties or utilize competitive loan products or state and local programs.

We also compete with solar companies with business models similar to our own, some of which are marketed to potential customers by our dealers, and we may also face competition from new entrants into the market as a result of the passage of the IRA and its anticipated impacts and benefits to the solar industry. Some of these competitors specialize in the distributed solar energy market and some may provide energy at lower costs than we do. Some of our competitors offer or may offer similar services and products as we do, such as leases, PPAs and direct outright sales of and consumer loan products for solar energy systems. Many of our competitors also have significant brand name recognition, lower barriers to entry into the solar market, greater capital resources than we have and extensive knowledge of our target markets.

We also compete with solar companies that offer community solar products and utility companies that provide renewable power purchase programs. Some customers might choose to subscribe to a community solar project or renewable subscriber programs instead of having a solar energy system installed on their home or business, which could affect our sales. Additionally, some utility companies (and some utility-like entities, such as community choice aggregators in California) have generation portfolios that are increasingly renewable in nature. In California, for example, utility companies and community choice aggregators in that state are required to have generation portfolios comprised of 60% renewable energy by 2030 and state regulators are planning for utility companies and community choice aggregators to sell 100% greenhouse gas free electricity to retail customers by 2045. As utility companies offer increasingly renewable portfolios to retail customers, those customers might be less inclined to have a solar energy system installed on their home or business, which could adversely affect our growth.

We have historically provided our services only to residential customers, but we have expanded to other markets, including commercial and industrial customers. There is intense competition in the solar energy sector in the markets in which we operate and the markets in which we intend to operate. As new entrants continue to enter into these markets, and as we enter into new markets, we may be unable to grow or maintain our operations and we may be unable to compete with companies that have already established themselves in both the residential market and non-residential markets.

As the solar industry grows and evolves, we will also face new competitors and technologies who are not currently in the market (including those resulting from the consolidation of existing competitors). Our industry is characterized by low technological barriers to entry and well-capitalized companies, including utilities and integrated energy companies, could choose to enter the market and compete with us. Our failure to adapt to changing market conditions and to compete successfully with existing or new competitors will limit our growth and will have a material adverse effect on our business, financial condition and results of operations.

***Developments in technology or improvements in distributed solar energy generation and related technologies or components may materially adversely affect demand for our offerings.***

Significant developments in technology, such as advances in distributed solar power generation, energy storage solutions such as batteries, energy storage management systems, the widespread use or adoption of fuel cells for residential or commercial properties or improvements in other forms of distributed or centralized power production may materially and adversely affect demand for our offerings and otherwise affect our business. Future technological advancements may result in

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

reduced prices to consumers or more efficient solar energy systems than those available today, either of which may result in current customer dissatisfaction. We may not be able to adopt these new technologies as quickly as our competitors or on a cost-effective basis.

Due to the length of our solar service agreements, the solar energy system deployed on a customer's property may be outdated prior to the expiration of the term of the related solar service agreement, reducing the likelihood of renewal of our solar service agreement at the end of the applicable term and possibly increasing the occurrence of customers seeking to terminate or cancel their solar service agreements or defaults. If current customers become dissatisfied with the price they pay for their solar energy system under our solar service agreements relative to prices that may be available in the future or if customers become dissatisfied by the output generated by their solar energy systems relative to future solar energy system production capabilities, or both, this may lead to customers seeking to terminate or cancel their solar service agreements or higher rates of customer default and have an adverse effect on our business, financial condition and results of operations. Additionally, recent technological advancements may impact our business in ways we do not currently anticipate. Any failure by us to adopt or have access to new or enhanced technologies or processes, or to react to changes in existing technologies, could result in product obsolescence or the loss of competitiveness of and decreased consumer interest in our solar energy services, which could have a material adverse effect on our business, financial condition and results of operations.

***Obtaining a customer contract with a potential customer does not guarantee the potential customer will not decide to cancel or that we will not need to cancel due to a failed inspection, which could cause us to generate no revenue despite incurring costs and adversely affect our results of operations.***

Even after we secure a customer contract with a potential customer, we (either through our dealers or directly) must perform an inspection to ensure the home, including the rooftop, meets our standards and specifications. If the inspection finds repairs to the rooftop are required in order to satisfy our standards and specifications to install the solar energy system, and a potential customer does not want to make such required repairs, we would lose that anticipated sale. In addition, per the terms of our customer contracts, a customer maintains the ability to cancel before commencement of installation, subject to certain conditions. Any delay or cancellation of an anticipated sale could materially and adversely affect our financial results, as we may have incurred sales-related, design-related and other expenses and generated no revenue.

***The value of our solar energy systems at the end of the associated term of the lease or PPA may be lower than projected, which may adversely affect our financial performance, results of operations and valuation.***

We depreciate the costs of our solar energy systems over their estimated useful life of 35 years. At the end of the initial term (typically 20 or 25 years) of the lease or PPA, customers may choose to purchase their solar energy systems, ask us to remove the solar energy system at our cost or renew their lease or PPA. Home and business owners may choose to not renew or purchase for any reason, such as pricing, decreased energy consumption, relocation, switching to a competitor product or technological obsolescence of the solar energy system. We are also contractually obligated to remove, store and reinstall the solar energy systems, typically for a nominal fee, if customers need to replace or repair their roofs. Furthermore, it is difficult to predict how future environmental regulations may affect the costs associated with the removal, disposal or recycling of our solar energy systems. If the residual value of the solar energy systems is less than we expect at the end of the customer contract, after giving effect to any associated removal and redeployment costs, we may be required to accelerate the recognition of all or some of the remaining unamortized costs. This could materially impair our future results of operations.

**Risks Related to our Financing Activities**

***We need to obtain substantial additional financing arrangements to provide working capital and growth capital. If financing is not available to us on acceptable terms when needed, our ability to continue to grow our business would be materially adversely impacted.***

Distributed solar power is a capital-intensive business that relies heavily on the availability of debt and equity financing sources to fund solar energy system purchase, design, engineering and other capital expenditures. From our inception through December 31, 2022, we have raised more than $11.8 billion in total capital commitments from equity, debt and tax equity investors.

Our future success depends in part on our ability to raise capital from third-party investors and commercial sources, such as banks and other lenders, on competitive terms to help finance the deployment of our solar energy systems. We seek to minimize our cost of capital in order to improve profitability and maintain the price competitiveness of the electricity produced by, the payments for and the cost of our solar energy systems. We rely on access to capital, including through tax equity financing and indebtedness in the form of debt facilities and asset-backed securities, to cover the costs related to bringing our solar energy

systems and energy storage systems in service, although our customers ultimately bear responsibility for those costs pursuant to our solar service agreements.

To meet the capital needs of our growing business, we will need to obtain additional debt or equity financing from current and new investors. If any of our current debt or equity investors decide not to invest in us in the future for any reason, or decide to invest at levels inadequate to support our anticipated needs or materially change the terms under which they are willing to provide future financing, we will need to identify new investors and financial institutions to provide financing and negotiate new financing terms. In addition, our ability to obtain additional financing through the asset-backed securities market or other secured debt markets is subject to our having sufficient assets eligible for securitization as well as our ability to obtain appropriate credit ratings. If we are unable to raise additional capital in a timely manner, our ability to meet our capital needs and fund future growth may be limited.

Delays in obtaining financing could cause delays in expansion in existing markets or entering into new markets and hiring additional personnel. Any future delays in capital raising could similarly cause us to delay deployment of a substantial number of solar energy systems for which we have signed solar service agreements with customers. Our future ability to obtain additional financing depends on banks' and other financing sources' continued confidence in our business model and the renewable energy industry as a whole. It could also be impacted by the liquidity needs of such financing sources themselves. We face intense competition from a variety of other companies, technologies and financing structures for such limited investment capital. If we are unable to continue to offer a competitive investment profile, we may lose access to these funds or they may only be available to us on terms less favorable than those received by our competitors. For example, if we experience higher customer default rates than we currently experience, it could be more difficult or costly to attract future financing. Any inability to secure financing could lead us to cancel planned installations, impair our ability to accept new customers or increase our borrowing costs, any of which could have a material adverse effect on our business, financial condition and results of operations.

***We enter into securitization structures, warehouse financings and other debt financings that may limit our ability to access the cash of our subsidiaries and include acceleration events that, if triggered, could adversely impact our financial condition.***

Since April 2017, we have pooled and transferred eligible solar energy systems and the related asset receivables into 15 special purpose entities, which sold solar asset-backed notes and solar loan-backed notes to institutional investors, the net proceeds of which were distributed to us. We intend to monetize additional solar energy systems in the future through contributions to new special purposes entities for cash. There is a risk the institutional investors that have purchased the notes issued by these special purpose entities will be unwilling to make further investments in our solar energy systems at attractive prices. Although the creditors of these special purpose entities have no recourse to our other assets except as expressly set forth in the terms of the notes, the special purpose entities are typically required to maintain a liquidity reserve account, a reserve account for equipment replacements, as well as, in certain cases, reserve accounts to finance purchase option/withdrawal right exercises, storage system replacement or payment of liquidated damages for the benefit of the lenders under the applicable series of notes, each of which are funded from initial deposits or cash flows to the levels specified therein.

The securitization structures, warehouse financings and other debt financings often include certain other features designed to protect investors. The primary feature relates to the availability and adequacy of cash flows in the pool of assets to meet contractual requirements, the insufficiency of which triggers an early repayment of the indebtedness. We refer to this as "early amortization", which may be based on, among other things, a debt service coverage ratio falling or remaining below certain levels. In the event of an early amortization, the notes issuer would be required to repay the affected indebtedness using available collections received from the asset pool. However, the period of ultimate payment would be determined based on the amount and timing of collections received and, in limited circumstances, early amortization may be cured prior to full repayment. An early amortization event would impair our liquidity and may require us to utilize other available contingent liquidity or rely on alternative funding sources, which may not be available at the time. Certain of the securitizations, warehouse financings and other debt financings also contain a "cash trap" feature, which requires excess cash flow to be held in an account based on, among other things, a debt service coverage ratio falling or remaining below certain levels. If the cash trap conditions are not cured within a specified period, then the cash in the cash trap account must be applied to repay the indebtedness. If the cash trap conditions are timely cured, the cash is either released back to the borrower or used to repay the indebtedness at the borrower's option. The indentures of our securitizations also typically contain customary events of default for solar securitizations that may entitle the noteholders to take various actions, including the acceleration of amounts due and foreclosure on the issuer's assets. Any significant payments we may be required to make as a result of these arrangements could adversely affect our financial condition. See "*Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Financing Arrangements*".

***Servicing our existing debt requires a significant amount of cash. We may not have sufficient cash flow from our business to timely pay our interest and principal obligations and may be forced to take other actions to satisfy our payment obligations.***

As of December 31, 2022, our total indebtedness was approximately $5.4 billion and the available borrowing capacity under our credit facilities was $174.3 million. Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not generate cash flow from operations sufficient to service our debt and make necessary capital expenditures to operate our business. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as slowing or ceasing the origination of new solar service agreements, selling assets, restructuring debt or obtaining additional debt and equity capital on terms that may be onerous or highly dilutive. Our securitizations are structured in that cash flows generated by the pool of solar energy systems, energy storage systems and related solar service agreements are initially used to repay outstanding principal amounts based on the priority of payments in the agreement. However, should these cash flows decrease below applicable thresholds, all excess cash flows from such asset pool must be applied to pay down the related indebtedness, which would reduce the cash available to otherwise fund our business. Our ability to timely repay or otherwise refinance our indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations.

Furthermore, we and our subsidiaries expect to incur additional debt in the future, subject to the restrictions contained in our debt instruments. Increases in our existing debt obligations would further heighten the debt related risk discussed above. In addition, we may not be able to enter into new debt instruments on acceptable terms or at all. If we were unable to satisfy financial covenants and other terms under existing or new instruments, or obtain waivers or forbearance from our lenders, or if we were unable to obtain refinancing or new financings for our working capital, equipment and other needs on acceptable terms if and when needed, our business would be adversely affected.

***Restrictive covenants in certain of our debt agreements could limit our growth and our ability to finance our operations, fund our capital needs, respond to changing conditions and engage in other business activities that may be in our best interests.***

Our debt agreements impose operating and financial restrictions on us. These restrictions limit our ability and that of our subsidiaries to, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;incur additional indebtedness;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;make investments or loans;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;create liens;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;consummate mergers and similar fundamental changes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;make restricted payments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;make investments in unrestricted subsidiaries;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;enter into transactions with affiliates; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;use the proceeds of asset sales.

We may be prevented from taking advantage of business opportunities that arise because of the limitations imposed on us by the restrictive covenants under certain of our debt agreements. The restrictions contained in the covenants could:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;limit our ability to plan for or react to market conditions, to meet capital needs or otherwise to restrict our activities or business plan; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;adversely affect our ability to finance our operations, enter into acquisitions or divestitures to engage in other business activities that would be in our interest.

A breach of any of these covenants or our inability to comply with the required financial ratios or financial condition tests could result in a default under our debt agreements that, if not cured or waived, could result in acceleration of all indebtedness outstanding thereunder and cross-default rights under our other debt. In addition, in the event of an event of default under one of the credit facilities, the affected lenders could foreclose on the collateral securing such credit facility and require repayment of all borrowings outstanding thereunder. If the amounts outstanding under the credit facilities or any of our other indebtedness were to be accelerated, our assets may not be sufficient to repay in full the amounts owed to the lenders or to our other debt holders.

***Volatility and continued increases in interest rates would raise our cost of capital and may adversely impact our business.***

Due to recent increases in inflation, the U.S. Federal Reserve has raised its benchmark interest rates. Further increases in the federal benchmark rate could result in an increase in market interest rates, which may increase our interest expense under our variable-rate borrowings and the costs of refinancing existing indebtedness or obtaining new debt. For example, borrowings under our existing warehouse credit facilities accrue interest based on the Secured Overnight Financing Rate ("SOFR") as a benchmark for establishing the rate of interest. Consequently, rising interest rates or continued higher interest rates will increase our cost of capital and may decrease the amount of capital available to us to finance deployment of new solar energy systems and energy storage systems. Our future success depends in part on our ability to raise capital from investors and obtain secured lending to help finance the deployment of our solar service agreements. As a result, rising interest rates may have an adverse impact on our ability to offer attractive pricing on our solar service agreements to our customers. If in the future we have a need for significant borrowings and interest rates increase or continue at high interest rates, that may increase the cost of the solar energy systems we purchase, which either would make those systems more expensive for customers, which is likely to reduce demand, or would lower our operating margins, or both.

The majority of our cash flows to date have been from solar service agreements monetized under various tax equity fund structures and secured lending arrangements. One of the components of this monetization is the present value of the payment streams from customers who enter into these long-term solar service agreements. If the rate of return required by capital providers, including debt providers, rises as a result of a rise in interest rates, it will reduce the present value of the customer payment stream and consequently reduce the total value derived from this type of monetization. Any measures we could take to mitigate the impact of rising interest rates on our ability to secure third-party financing could ultimately have an adverse impact on the value proposition we offer our customers or our profitability.

***We may not have the ability to raise the funds necessary to settle conversions of the Convertible Notes in cash or to repurchase the Convertible Notes upon a fundamental change, and our future debt may contain limitations on our ability to pay cash upon conversion or repurchase of the Convertible Notes.***

Holders of the 0.25% convertible senior notes and 2.625% convertible senior notes (the "Convertible Notes") will have the right to require us to repurchase all or a portion of their Convertible Notes upon the occurrence of a fundamental change under the indenture, which includes certain events such as a change of control, before the maturity date at a fundamental change repurchase price equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid special interest, if any. In addition, upon conversion of the Convertible Notes, unless we elect to deliver solely shares of our common stock to settle such conversion (other than paying cash in lieu of delivering any fractional share), we will be required to make cash payments in respect of the Convertible Notes being converted. However, we may not have enough available cash or be able to obtain financing at the time we are required to make repurchases of Convertible Notes surrendered therefor or pay cash for Convertible Notes being converted. In addition, our ability to repurchase the Convertible Notes or to pay cash upon conversions of the Convertible Notes may be limited by law, by regulatory authority or by agreements governing our indebtedness at the time.

Our failure to repurchase Convertible Notes at a time when the repurchase is required by the indenture governing such Convertible Notes or to pay any cash payable on future conversions of the Convertible Notes as required by the indenture would constitute a default. A default under the indenture or the fundamental change itself could also lead to a default under agreements governing our existing or future indebtedness. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the Convertible Notes or make cash payments upon conversions thereof.

***We are subject to counterparty credit risk with respect to the capped call transactions.***

In connection with the pricing of the Convertible Notes, we entered into privately negotiated capped call transactions with certain financial institutions (the "option counterparties"). The option counterparties are financial institutions or affiliates of financial institutions, and we will be subject to the risk that one or more of such option counterparties may default or otherwise fail to perform their obligations under the capped call transactions. Our exposure to the credit risk of the option counterparties will not be secured by any collateral.

If any option counterparty becomes subject to bankruptcy or other insolvency proceedings, with respect to such option counterparty's obligations under the relevant capped call transaction, we will become an unsecured creditor in those proceedings with a claim equal to our exposure at that time under our transactions with that counterparty. Our exposure will depend on many factors but, generally, our exposure will increase if the market price or the volatility of our common stock increases. In addition, upon a default or other failure to perform by an option counterparty, we may suffer more dilution than we

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

currently anticipate with respect to our common stock. We can provide no assurance as to the financial stability or viability of any of the option counterparties.

***We may be required to make payments or contribute assets to our investors upon the occurrence of certain events, including one-time reset or true-up payments or upon the exercise of a redemption option by one of our tax equity investors.***

Our investors in our tax equity investment funds typically advance capital to us based on, among other things, production capacity estimates. The models we use to calculate prepayments in connection with certain of our tax equity investment funds are updated at a fixed date occurring after placement in service of all applicable solar energy systems or an agreed upon date (typically within the first year of the applicable term) to reflect certain specified conditions, as they exist at such date including the ultimate system size of the equipment that was sold or leased to the tax equity investment fund, the cost thereof, and the date the equipment went into service. In some cases, these true-up models also incorporate any changes in law, which would include any reduction in rates (and thus any reduction in the benefits of depreciation). As a result of this true-up, applicable payments are resized, and we may be obligated to refund a portion of the tax equity investor's prepayments or to contribute additional assets to the tax equity investment fund. In addition, certain of our tax equity fund investors have the right to require us to purchase their interests in the tax equity investment funds after a set period of time, generally at a price equal to the greater of a set purchase price or fair market value of the interests at the time of the repurchase. Any significant refunds, capital contributions or purchases we may be required to make could adversely affect our liquidity or financial condition.

**Risks Related to Regulations**

***We are not currently regulated as an electric public utility under applicable law but may be subject to regulation as an electric utility in the future.***

We are not currently regulated as an electric public utility in the U.S. under applicable national, state or other local regulatory regimes where we conduct business. As a result, we are not currently subject to the various federal, state and local standards, restrictions and regulatory requirements applicable to centralized public utilities. Any federal, state or local regulations that cause us to be treated as an electric utility or to otherwise be subject to a similar regulatory regime of commission-approved operating tariffs, rate limitations and related mandatory provisions, could place significant restrictions on our ability to operate our business and execute our business plan by prohibiting, restricting or otherwise regulating our sale of electricity. If we were subject to the same state or federal regulatory authorities as centralized electric utilities in the U.S. and its territories or if new regulatory bodies were established to oversee our business in the U.S. and its territories or in foreign markets we enter, our operating costs would materially increase or we might have to change our business in ways that could have a material adverse effect on our business, financial condition and results of operations.

While we are not regulated as extensively as an electric public utility, we are subject to certain utility-like regulations in jurisdictions such as California, New York, Arizona, Nevada, Florida and Puerto Rico. In New York, distributed energy providers are subject to regulation by the New York Public Service Commission (the "NYPSC") with respect to customer interactions (including contracting and marketing) and are required to comply with the NYPSC's Uniform Business Practices. In connection with approving the Uniform Business Practices, the NYPSC also established an oversight framework under which it could impose other regulatory requirements on distributed energy providers. In Puerto Rico, we are regulated as an electric power company under applicable PREB regulations in connection with the sale and invoicing of energy generated by distributed generation systems having an aggregate capacity of more than 1 megawatt. Among other requirements, these regulations impose certain filing, certification, reporting and annual fee requirements upon us but do not currently subject the companies to centralized utility-like regulation or require the PREB's approval of their charges. In California, the CPUC issued an order approving several consumer protection measures for solar customers, including a requirement for solar providers to provide customers with the California Solar Consumer Protection Guide, which provides customers with information regarding the selection of a contractor, solar financing, bill savings estimates, net energy metering and electric rates, low-income options and related matters. The CPUC order also requires the investor-owned utilities in California to adopt procedures to verify during the interconnection process that the customer received the California Solar Consumer Protection Guide and that the solar provider is licensed, and to collect and report on complaints regarding solar providers. If we become subject to new, additional regulatory requirements in these jurisdictions or other jurisdictions adopt similar regulatory requirements, our operating costs would materially increase or we might have to change our business in ways that could have a material adverse effect on our business, financial condition and results of operations.

***Electric utility policies and regulations, including those affecting electric rates, may present regulatory and economic barriers to the purchase and use of solar energy systems that may significantly reduce demand for electricity from our solar energy systems and adversely impact our ability to originate new solar service agreements.***

Federal, state and local government regulations and policies concerning the electric utility industry, utility rates and rate structures and internal policies and regulations promulgated by electric utilities, heavily influence the market for electricity generation products and services. These regulations and policies often relate to electricity pricing. Policies and regulations that promote renewable energy and distributed energy generation have been challenged by centralized electric utilities and questioned by those in government and others arguing for less governmental spending and involvement in the energy market. To the extent such views are reflected in government policies and regulations, the changes in such policies and regulations could adversely affect our business, financial condition and results of operations. Furthermore, any effort to overturn federal and state laws, regulations or policies that are supportive of solar energy generation or that remove costs or other limitations on other types of energy generation that compete with solar energy projects could materially and adversely affect our business.

In the U.S., governmental authorities and state public service commissions that determine utility rates, rate structures and the terms and conditions of electric service continuously modify these regulations and policies. These regulations and policies could result in a significant reduction in the potential demand for electricity from our solar energy systems and could deter customers from entering into solar service agreements with us.

With regard to rates, customers with solar energy systems may currently pay or be subject in the future to increased charges due to increased rates or changes in rate design and structures. Utilities in certain jurisdictions may assess fees that apply only to customers with distributed generation systems, including residential or non-residential solar energy systems or impose charges on solar customers that are significantly higher than comparable charges billed to non-solar customers.

These fees may include demand, stand-by or departing load charges or monthly minimum charges. Certain jurisdictions may permit utilities to change their rate design and structures which could result in charges that would disproportionately impact customers with solar energy systems. For example, a reduction in the number of tiers of rates could result in increased charges for lower-demand customers, including many solar customers, by moving them to a new rate tier with higher rates. It could also result in lower charges for higher-demand customers, who may then become less incentivized to consider solar energy to meet their electricity needs. Similarly, a change in rate design to recover more costs from fixed charges as opposed to variable charges (i.e. "decoupled" rates, by which the utility's revenue requirement is "decoupled" from its level of electricity sales in designing rates) may have the same effect. Additionally, depending on the region, electricity generated by solar energy systems competes most effectively with the most expensive retail rates for electricity from the electrical grid, rather than the less expensive average price of electricity. Modifications to the centralized electric utilities' peak hour pricing policies or rate design could make our current product offerings less competitive with the price of electricity from the electrical grid. A shift in the timing of peak rates for utility-generated electricity to include times of day when solar energy generation is less efficient or non-operable could make our solar energy systems less competitive and reduce demand for our product offerings. Time-of-use rates could also result in higher costs for solar customers whose electricity requirements are not fully met by the solar energy system during peak periods.

Utilities in California, New Jersey and Puerto Rico, among other states and jurisdictions, have proposed or received approval by state regulators for such rate measures as described in this risk factor. Any such changes affecting rates could increase our customers' cost to use our solar energy systems and make our service and product offerings less desirable, thereby harming our business, financial condition and results of operations. The imposition of any such rate measures could limit the ability of distributed solar power companies to compete with the price of electricity generated by centralized electric utilities, which may reduce the number of solar energy systems installed in those jurisdictions. Additionally, any such unaccounted for increases in the fees or charges applicable to existing customer agreements may increase the cost of energy to those customers and result in an increased rate of defaults, terminations or cancelations under our solar service agreements. In addition, changes to government or internal utility regulations and policies that favor centralized electric utilities could reduce our competitiveness and cause a significant reduction in demand for our product offerings.

Any of the foregoing results could limit our ability to expand our portfolio of solar service agreements and related solar energy systems and energy storage systems or harm our business, financial condition and results of operations.

***We rely on net metering and related policies to offer competitive pricing to our customers in most of our current markets and changes to net metering policies may significantly reduce demand for electricity from solar energy systems.***

Net metering is one of several key policies that have enabled the growth of distributed generation solar energy systems in the U.S., providing significant value to certain qualifying residential and commercial customers for electricity generated by

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

their solar energy systems but not directly consumed on-site. Net metering allows a homeowner or a business to pay the local electric utility for power usage net of production from the solar energy system or other distributed generation source. Homeowners or businesses receive a credit for the energy an interconnected solar energy system generates in excess of that needed by the home to offset energy purchases from the centralized utility made at times when the solar energy system is not generating sufficient energy to meet the customer's demand. In many markets, this credit is equal to the retail rate for electricity and in other markets, such as Hawaii and Nevada, the rate is less than the retail rate and may be set, for example, as a percentage of the retail rate or based upon a valuation of the excess electricity. In some states and utility territories, customers are also reimbursed by the centralized electric utility for net excess generation on a periodic basis.

Net metering programs have been subject to legislative and regulatory scrutiny in some states and territories including, but not limited to, California, New Jersey, Arizona, Nevada, Connecticut, Florida, Maine, Kentucky, Puerto Rico and Guam. These jurisdictions, by statute, regulation, administrative order or a combination thereof, have recently adopted or are considering new restrictions and additional changes to net metering programs either on a state-wide basis or within specific utility territories. Many of these measures were introduced and supported by centralized electric utilities. These measures vary by jurisdiction and may include a reduction in the rates or value of the credits customers are paid or receive for the power they deliver back to the electrical grid, caps or limits on the aggregate installed capacity of generation in a state or utility territory eligible for net metering, expiration dates for and phasing out of net metering programs, replacement of net metering programs with alternative programs that may provide less compensation and limits on the capacity size of individual distributed generation systems that can qualify for net metering. Net metering and related policies concerning distributed generation also received attention from federal legislators and regulators.

In California, the CPUC issued an order in 2016 retaining retail-based net metering credits for residential customers of California's major utilities as part of Net Energy Metering 2.0 ("NEM 2.0"). Under NEM 2.0, new distributed generation customers receive the retail rate for electricity exported to the grid, less certain non-bypassable fees. Customers under NEM 2.0 also are subject to interconnection charges and time-of-use rates. Existing customers who receive service under the prior net metering program, as well as new customers under the NEM 2.0 program, currently are permitted to remain covered by them on a legacy basis for a period of 20 years. On September 3, 2020, the CPUC opened a new proceeding to review its current net metering policies and to develop Net Energy Metering 3.0 ("NEM 3.0"), also referred to by the CPUC as the NEM 2.0 successor tariff. On December 15, 2022, the CPUC approved NEM 3.0 as successor program to its current net metering program that reduces the value of net metering credits from the retail rate to an avoided cost rate for customers that will have solar energy systems installed on their homes and businesses over the next five years. Customers will also be placed on an electrification rate. Residential customers located in the territories of two of the investor-owned utilities will also receive small adders to the avoided cost rate, while the residential customers in the territory of the third investor-owned utility, as well as new homes and commercial customers in all three of the service territories do not receive any adders. In addition, it may only be possible for customers to realize savings from installing solar energy systems compared to the utility retail rate by adding storage to their solar energy systems or undersizing them so exports are limited. The decision goes into effect in April 2023. Proceedings on distributed energy policy and utility rates before the CPUC or legislation concerning these matters could also result in changes that affect customers with distributed generation systems.

In New Jersey, the Board of Public Utilities has the option under state law of limiting participation in the retail rate net metering program if the aggregate capacity of owned and operating systems reaches 5.8% of total annual kWh sold in the state. As of December 31, 2022, that threshold had not yet been reached.

In Puerto Rico, legislation enacted in April 2019 requires a study of net metering to be completed within five years, which may result in revisions to the existing rules. However, no changes can be made to retail net metering for five years after the date the legislation was enacted. Meanwhile, "true" net metering will continue to apply, meaning the credit for energy exported by net metering clients will equal the value of such energy under the rate applicable to those clients and accordingly, their charges will be based on their net consumption. Customers subject to this regime will remain covered by it on a legacy basis for a period of 20 years from the date of their net metering agreements.

Net metering customers in Puerto Rico may be impacted by transition charges and other requirements contemplated in a restructuring agreement between PREPA and its creditors, currently pending before the U.S. District Court for the District of Puerto Rico in bankruptcy-like proceedings under Title III of the PROMESA. PROMESA provides PREPA with access to a workout process similar to bankruptcy. In response to the effects of the COVID-19 pandemic, however, the approval of the restructuring agreement has been stayed, and the government announced in December 2020 that it continues to conduct diligence to determine whether, among other things, the terms of the restructuring agreement should be renegotiated and the parameters for doing so.

In Guam, the Consolidated Commission on Utilities ("CCU") adopted a resolution in 2018 recommending retail rate net metering for customers of the Guam Power Authority ("GPA") be replaced with a "buy all/sell all" or similar program that provides for compensation to homeowners at a lower, avoided cost rate. The GPA is a public corporation that provides electricity in Guam and is overseen by the CCU and regulated by the Guam Public Utilities Commission ("GPUC"). In 2019, the GPUC, who has the authority to approve or reject the CCU's recommendations, rejected the resolution and instead voted to cap participation in the net metering program from 1,000 customers to 261 megawatts, which represents 10% of the GPA system's peak power demand. The GPA has also proposed to eliminate the option for customers to roll over any excess net metering credits to the next year or receive a payment for excess credits remaining at the end of the year. In May 2020, the GPUC approved the GPA's proposal to eliminate the option for customers to roll over any excess net metering credits or receive a payment for excess credits remaining at the end of the year. This change went into effect on January 1, 2021. Customers will be able to receive a payment for excess credits at the end of 2020, but any excess credits remaining at the end of a year in the future will be surrendered to the utility without compensation. In February 2020, the CCU adopted a resolution requiring all new distributed generation that participates in net metering and is tied to the GPA power grid to have an energy storage system such as a battery. The GPUC approved a February 2020 resolution by the CCU adopting additional requirements for new distributed generation that participates in net metering. Starting on June 1, 2021, new systems were required to have frequency control capability or energy storage, such as a battery, or else are required to pay an additional monthly charge to the GPA.

In other jurisdictions, including Austin, Texas, Minnesota and Connecticut, replacing net metering with a "value of distributed energy", "feed-in", or "sell-all/ buy-all" tariff is also being considered or has been adopted. Under a "value of distributed energy" tariff, the customer would be compensated at a rate that accounts for the electricity, capacity, environmental and other attributes provided by distributed generation to the grid and the electricity market. Under a "feed-in" or "sell-all/ buy-all" tariff, all the solar energy system's generation is exported to the grid and purchased by the utility at an established rate and the customer is required to purchase all of its electricity requirements from the utility at the retail rate. In New York, the NYPSC adopted a "value of distributed energy" policy but permitted existing net metering customers to remain on their current program and extended eligibility for net metering for new residential customers interconnected before January 1, 2022 for a period of 20 years. Residential customers otherwise still eligible for net metering may also elect to be compensated under a "value of distributed energy" tariff. New solar customers interconnecting after January 1, 2022 continue to be eligible for net metering, but will be subject to a monthly fixed fee. Compensation for those customers covered by a "value of solar" tariff varies and may not favorably compare to that provided by net metering.

Net metering and related policies concerning distributed generation have received attention from federal legislators and regulators and challenge by various stakeholders. For example, in April 2020, the New England Ratepayers Association petitioned the FERC to declare its exclusive federal jurisdiction over distributed generation, including residential solar, and to establish new federal customer compensation rates for excess energy in lieu of state net metering programs. While the FERC rejected the petition on procedural grounds, further challenges to net metering based on federal law may occur. Changes in federal law, including those made by statute, regulation, rule or order, could negatively affect net metering or other related policies that otherwise promote and support solar energy and enhance the economic viability of distributed solar.

If net metering caps in certain jurisdictions are reached while they are still in effect, if the value of the credit that customers receive for net metering is significantly reduced, if customers are required to pay monthly charges in order to participate in a net metering program, if net metering is discontinued or replaced by a different regime that values solar energy at a lower rate, if the period that net metering customers remain eligible for their current net metering program is reduced or if other limits or restrictions on net metering are imposed, current and future customers may be unable to recognize the same level of cost savings associated with net metering. The absence of favorable net metering policies or of net metering entirely, or the imposition of new charges that only or disproportionately impact customers that use net metering would likely significantly limit customer demand for distributed solar energy systems and the electricity they generate and result in an increased rate of defaults, terminations or cancelations under customer agreements. Our ability to lease, finance and sell our solar energy systems and services or sell the electricity generated from our solar energy systems may be adversely impacted by the failure to expand existing limits on the amount of net metering in states that have implemented it, the failure to adopt a net metering policy where it currently is not in place or reductions in the amount or value of credit customers receive through net metering. This could adversely impact our ability to expand our portfolio of solar service agreements and related solar energy systems and energy storage systems, our business, financial condition and results of operations.

Additionally, distributed solar customers in certain jurisdictions may be subject to higher charges from centralized electric utilities than non-solar customers and such charges should be evaluated together with the net metering policies in place. If such charges are imposed, the cost savings associated with switching to solar energy may be significantly reduced and our ability to expand our portfolio of solar service agreements and related solar energy systems and energy storage systems and compete with centralized electric utilities could be impacted.

For further discussion of these potential charges and related proposals, see "—*Electric utility policies and regulations, including those affecting electric rates, may present regulatory and economic barriers to the purchase and use of solar energy systems that may significantly reduce demand for electricity from our solar energy systems and adversely impact our ability to originate new solar service agreements*".

***Our business currently depends in part on the availability of rebates, tax credits and other financial incentives. The expiration, elimination or reduction of these rebates, credits or incentives or our ability to monetize them could adversely impact our business.***

Our business depends in part on current government policies that promote and support solar energy and enhance the economic viability of distributed solar. Revenues from SRECs constituted approximately 9%, 17% and 22% of our revenues for the years ended December 31, 2022, 2021 and 2020, respectively. U.S. federal, state and local governments established various incentives and financial mechanisms to reduce the cost of solar energy and to accelerate the adoption of solar energy. These incentives come in various forms, including rebates, tax credits and other financial incentives such as payments for renewable energy credits associated with renewable energy generation, exclusion of solar energy systems from property tax assessments or other taxes and system performance payments. However, these programs may expire on a particular date, end when the allocated funding is exhausted or be reduced or terminated as solar energy adoption rates increase. For example, New Jersey's SREC program closed in 2020 due to legislation requiring that it be closed by the earlier of the share of electricity sold by the state's utilities supplied by solar reaching 5.1% or June 2021. Following the close of the program in June 2020, customers became eligible for Transitional Renewable Energy Credits ("TRECs") under an interim transitional program replacing SRECs that provides for a lower level of revenue than the SREC program. On July 28, 2021, the New Jersey Board of Public Utilities closed the TREC program effective August 27, 2021 and approved the long-term successor program to the TREC program, which is referred to as the Successor Solar Incentive Program ("SuSI"). Under the SuSI program, which became effective on August 28, 2021, residential facilities are eligible for the Solar Renewable Energy Certificate-II ("SREC-II") incentive. For net metered residential facilities, the SREC-II provides an administratively-determined fixed payment per megawatt hour that is guaranteed for 15 years, but is lower than the level revenue provided by the TREC program. The financial value of certain incentives decreases over time. The value of SRECs in a market tends to decrease over time as the supply of SREC-producing solar energy systems installed in that market increases. If we overestimate the future value of these incentives, it could adversely impact our business, results of operations and financial results. See "*Business—Government Incentives*".

A loss or reduction in such incentives could decrease the attractiveness of new solar energy systems to customers, which could adversely impact our business and our access to capital. We also enter into economic hedges related to expected production of SRECs through forward contracts that require us to physically deliver the SRECs upon settlement. These arrangements may, depending on the instruments used and the level of additional hedges involved, limit any potential upside from SREC production increases. We may be exposed to potential economic loss should a counterparty be unable or unwilling to perform their obligations under the terms of a hedging agreement. In addition, we are exposed to risks related to changes in interest rates and may engage in hedging activities to mitigate related volatility. We may fail to properly hedge these SRECs or may fail to do so economically, which may also adversely affect our results of operations.

The economics of purchasing a solar energy system and energy storage system are also improved by eligibility for accelerated depreciation, also known as the modified accelerated cost recovery system ("MACRS"), which allows for the depreciation of equipment according to an accelerated schedule set forth by the IRS. This accelerated schedule allows a taxpayer, such as us and investors in tax equity financing arrangements, to recognize the depreciation of tangible solar property on a five-year basis even though the useful life of such property is generally greater than five years. We benefit from accelerated depreciation on the solar energy systems and energy storage systems we own. To the extent these policies are changed in a manner that reduces the incentives that benefit our business, we may experience reduced revenues and reduced economic returns, experience increased financing costs and encounter difficulty obtaining financing.

The federal government currently provides for the Section 48(a) ITC, the Section 48E ITC for eligible property that begins construction after 2024 and the Section 25D Credit. Under current law, the Section 48(a) ITC of the Code allows taxpayers to claim an investment tax credit which, depending on the location of a particular project, its size, its ability to satisfy certain labor and domestic content requirements and the category of consumers it serves, can range between 6% and 70% of the basis of certain commercially owned energy property, in each case construction of which begins before 2025. The Section 48E ITC percentage generally will be the same as the percentage for the Section 48(a) ITC. The Section 48E ITC percentage will begin to phase down for projects that began construction after (a) 2033 or (b) if later, the first year after the year in which the U.S. Treasury Department determines greenhouse gas emissions from the production of electricity in the U.S. are no more than 25% of 2022 levels. To be eligible for the Section 48(a) ITC or the Section 48E ITC at no lower than the 30% level, the eligible energy property must either (a) meet certain labor and apprenticeship requirements, (b) have a maximum net output of less than one megawatt (as measured in alternating current) or (c) begin construction prior to January 29, 2023. Beginning in 2023, we

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

are able to claim the Section 48(a) ITC or the Section 48E ITC, as applicable, for energy storage systems regardless of whether such systems are installed in conjunction with solar energy systems. We would be able to claim the Section 48(a) ITC or the Section 48E ITC, as applicable, when available for solar energy systems or energy storage systems we originate under lease agreements or PPAs based on our ownership of the solar energy system at the time it is placed in service.

Section 25D of the Code allows an individual to claim a 30% federal tax credit with respect to a residential solar energy system and/or energy storage system that is owned by the homeowner. As a result, the Section 25D Credit is claimed by customers who purchase solar energy systems and/or energy storage systems. This Section 25D Credit will remain at 30% through the end of 2032, reduce to 26% for 2033, reduce to 22% for 2034 and further reduce to 0% after 2034, unless it is extended before that time. The Section 25D Credit reduces the cost of consumer ownership of solar energy systems and/or energy storage systems, such as under the loan program.

The Section 48(a) ITC has been a significant driver of the financing supporting the adoption of residential solar energy systems in the U.S. and the Section 25D Credit has been a significant driver of consumer demand for ownership of solar energy systems. Any reduction in, or expiration of, these tax credits will likely impact the attractiveness of residential solar and could harm our business. For example, we expect the expiration of the Section 25D Credit will increase the cost of consumer ownership of solar energy systems, such as under the loan program.

Applicable authorities may adjust or decrease incentives from time to time or include provisions for minimum domestic content requirements or other requirements to qualify for these incentives. Reductions in, eliminations or expirations of or additional application requirements for governmental incentives could adversely impact our results of operations and ability to compete in our industry by increasing our cost of capital, causing distributed solar power companies to increase the prices of their energy and solar energy systems and reducing the size of our addressable market. In addition, this would adversely impact our ability to attract investment partners and lenders and our ability to expand our portfolio of solar service agreements and related solar energy systems and energy storage systems. See "*Business—Government Incentives*".

***Our business depends in part on the regulatory treatment of third-party owned solar energy systems.***

Our lease and PPA agreements are third-party ownership arrangements. Retail sales of electricity by third parties such as us face regulatory challenges in some states and jurisdictions, including states and jurisdictions we intend to enter where the laws and regulatory policies have not historically embraced competition to the service provided by the vertically integrated centralized electric utility. Some of the principal challenges pertain to whether third-party owned solar energy systems qualify for the same levels of rebates or other non-tax incentives available for customer-owned solar energy systems, whether third-party owned solar energy systems are eligible at all for these incentives and whether third-party owned solar energy systems are eligible for net metering and the associated significant cost savings. Furthermore, in some states and utility territories, third parties are limited in the way they may deliver solar to their customers. In certain jurisdictions, laws have been interpreted to prohibit the sale of electricity pursuant to PPAs, leading distributed solar energy system providers to use leases in lieu of PPAs, in addition to customer ownership. These regulatory constraints may, for example, give rise to various property tax issues. See "*Risks Related to Taxation*". Changes in law and reductions in, eliminations of or additional requirements for, benefits such as rebates, tax incentives and favorable net metering policies decrease the attractiveness of new solar energy systems to distributed solar power companies and the attractiveness of solar energy systems to customers, which could reduce our acquisition opportunities. Such a loss or reduction could also adversely impact our access to capital and reduce our willingness to pursue solar energy systems due to higher operating costs or lower revenues from leases and PPAs.

***Technical and regulatory limitations regarding the interconnection of solar energy systems to the electrical grid may significantly reduce our ability to sell electricity from our solar energy systems in certain markets or delay interconnections and customer in-service dates, harming our growth rate and customer satisfaction.***

Technical and regulatory limitations regarding the interconnection of solar energy systems to the electrical grid may curb or slow our growth in key markets. Utilitie*s* throughout the country follow different rules and regulations regarding interconnection and regulators or utilities have or could cap or limit the amount of solar energy that can be interconnected to the grid. Our solar energy systems generally do not provide power to home and business owners until they are interconnected to the grid.

With regard to interconnection limits, the FERC, in promulgating the first form of small generator interconnection procedures, recommended limiting customer-sited intermittent generation resources, such as our solar energy systems, to a certain percentage of peak load on a given electrical feeder circuit. Similar limits have been adopted by many states as a de facto standard and could constrain our ability to market to customers in certain geographic areas where the concentration of solar installations exceeds this limit.

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

Furthermore, in certain areas, we benefit from policies that allow for expedited or simplified procedures related to connecting solar energy systems and energy storage systems to the electrical grid. We also are required to obtain interconnection permission for each solar energy system from the local utility. In many states and territories, by statute, regulations or administrative order, there are standardized procedures for interconnecting distributed solar energy systems and related energy storage systems to the electric utility's local distribution system. However, approval from the local utility could be delayed as a result of a backlog of requests for interconnection or the local utility could seek to limit the number of customer interconnections or the amount of solar energy on the grid. In some states, such as New Jersey and Massachusetts, certain utilities such as municipal utilities or electric cooperatives are exempt from certain interconnection requirements. If expedited or simplified interconnection procedures are changed or cease to be available, if interconnection approvals from the local utility are delayed or if the local utility seeks to limit interconnections, this could decrease the attractiveness of new solar energy systems and energy storage systems to distributed solar power companies, including us, and the attractiveness of solar energy systems and energy storage systems to customers. Delays in interconnections could also harm our growth rate and customer satisfaction scores. Such limitations or delays could also adversely impact our access to capital and reduce our willingness to pursue solar energy systems and energy storage systems due to higher operating costs or lower revenues from solar service agreements. Such limitations would negatively impact our business, results of operations, future growth and cash flows.

As adoption of solar distributed generation rises, along with the increased operation of utility-scale solar generation (such as in key markets including California), the amount of solar energy being contributed to the electrical grid may surpass the capacity anticipated to be needed to meet aggregate demand. If solar generation resources reach a level capable of producing an over-generation situation, some existing solar generation resources may have to be curtailed to maintain operation of the electrical grid. In the event such an over-generation situation were to occur, this could also result in a prohibition on the addition of new solar generation resources. The adverse effects of such a curtailment or prohibition without compensation could adversely impact our business, results of operations, future growth and cash flows.

***We and our dealers are subject to risks associated with construction, regulatory compliance and other contingencies.***

We utilize our growing dealer network to market, design, construct and install solar energy systems and energy storage systems in each of the markets in which we operate. The marketing and installation of solar energy systems and energy storage systems is subject to oversight and regulation in accordance with national, state and local laws and ordinances related to consumer protection, building, fire and electrical codes, professional codes, safety, environmental protection, utility interconnection, metering and related matters. We also rely on certain of our dealers and third-party contractors to obtain and maintain permits and professional licenses, including as contractors, and other authorizations from various regulatory authorities and abide by their respective conditions and requirements in many of the jurisdictions in which we operate, as well as perform permitting and installation of solar energy systems and energy storage systems using or complying with government sponsored platforms such as SolarAPP+. A failure by us to obtain necessary permits or encounter delays in obtaining or renewing such permits or to use properly licensed dealers and third-party contractors or to use government-sponsored or government-mandated platforms could adversely affect our operations in those jurisdictions. Furthermore, we may become subject to similar regulatory requirements in some jurisdictions in which we operate. It is difficult and costly to track the requirements of every authority with jurisdiction over our operations and our solar energy systems. Separately, we are subject to regulations and potential liability under the Resource Conservation and Recovery Act and the Comprehensive Environmental Response, Compensation, and Liability Act related to the disposal of wastes generated in connection with our operations. Regulatory authorities may impose new government regulations or utility policies, change existing government regulations or utility policies, may seek expansive interpretations of existing regulations or policies pertaining to our services or solar energy systems and energy storage systems or may initiate associated investigations or enforcement actions or impose penalties or reject solar energy systems and energy storage systems. Any of these factors may result in regulatory and/or civil litigation, significant additional expenses to us or our customers, cause delays in our or our dealers' ability to originate solar service agreements or install or interconnect solar energy systems and energy storage systems or cause other harm to our business. As a result, this could cause a significant reduction in demand for our services and solar energy systems and energy storage systems or otherwise adversely affect our business, financial condition and results of operations.

***Compliance with occupational safety and health requirements and best practices can be costly and noncompliance with such requirements may result in potentially significant monetary penalties, operational delays and adverse publicity.***

The installation and ongoing operations and maintenance of solar energy systems and energy storage systems requires individuals hired by us, our dealers or third-party contractors, potentially including our employees, to work at heights with complicated and potentially dangerous electrical systems. The evaluation and modification of buildings as part of the installation process requires these individuals to work in locations that may contain potentially dangerous levels of asbestos, lead, mold or other materials known or believed to be hazardous to human health. There is substantial risk of serious injury or

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

death if proper safety procedures are not followed. Our operations are subject to regulation under OSHA, DOT regulations and equivalent state and local laws. Changes to OSHA or DOT requirements, or stricter interpretation or enforcement of existing laws or regulations, could result in increased costs. If we fail to comply with applicable OSHA or DOT regulations, even if no work-related serious injury or death occurs, we may be subject to civil or criminal enforcement and be required to pay substantial penalties, incur significant capital expenditures or suspend or limit operations. Because individuals hired by us or on our behalf to perform installation and ongoing operations and maintenance of our solar energy systems and energy storage systems, including our dealers and third-party contractors, are compensated on a per project basis, they are incentivized to work more quickly than installers compensated on an hourly basis. While we have not experienced a high level of injuries to date, this incentive structure may result in higher injury rates than others in the industry and could accordingly expose us to increased liability. Individuals hired by or on behalf of us may have workplace accidents and receive citations from OSHA regulators for alleged safety violations, resulting in fines. Any such accidents, citations, violations, injuries or failure to comply with industry best practices may subject us to adverse publicity, damage our reputation and competitive position and adversely affect our business.

***A failure to comply with laws and regulations related to interactions by us or our dealers with current or prospective customers could result in negative publicity, claims, investigations and litigation and adversely affect our financial performance.***

Our business substantially focuses on solar service agreements and transactions with customers. We offer leases, loans and other products and services to consumers by contractors in our dealer networks, who utilize sales people employed by or engaged as third-party service providers of such contractors. We and our dealers must comply with numerous federal, state and local laws and regulations that govern matters related to interactions with consumers, including those pertaining to consumer protection, marketing and sales, privacy and data security, consumer financial and credit transactions, mortgages and refinancings, home improvement contracts, warranties and various means of customer solicitation, including under the laws identified in "*—Our business is subject to consumer protection laws. Such laws and regulatory enforcement policies and priorities are subject to change that may negatively impact our business"*. These laws and regulations are dynamic and subject to potentially differing interpretations and various federal, state and local legislative and regulatory bodies may initiate investigations, expand current laws or regulations, or enact new laws and regulations regarding these matters. Changes in these laws or regulations or their interpretation could dramatically affect how we and our dealers do business, acquire customers and manage and use information collected from and about current and prospective customers and the costs associated therewith. We and our dealers strive to comply with all applicable laws and regulations related to interactions with residential and non-residential customers. It is possible, however, these requirements may be interpreted and applied in a manner inconsistent from one jurisdiction to another and may conflict with other rules or the practices of us or our dealers.

Although we require our dealers to meet our consumer compliance requirements and provide regular training to help them do so, we do not control our dealers and their suppliers or their business practices. Accordingly, we cannot guarantee they follow ethical business practices such as fair wage practices and compliance with environmental, safety and other local laws. A lack of demonstrated compliance could lead us to seek alternative dealers or suppliers, which could increase our costs and have a negative effect on our business and prospects for growth. Violation of labor or other laws by our dealers or suppliers or the divergence of a dealer or supplier's labor or other practices from those generally accepted as ethical in the U.S. or other markets in which we do or intend to do business could also attract negative publicity for us and harm our business.

From time to time, we have been included in lawsuits brought by the customers of certain contractors in our networks, citing claims based on the sales practices of these contractors. While we have paid only minimal damages to date, we cannot be sure that a court of law would not determine that we are liable for the actions of the contractors in our networks or that a regulator or state attorney general's office may hold us accountable for violations of consumer protection or other applicable laws by the contractors in selling our loans, leases, and other products and services. Our risk mitigation processes may not be sufficient to mitigate financial harm to us associated with violations of applicable law by our contractors or ensure that any such contractor is able to satisfy its indemnification obligations to us. Any significant judgment against us could expose us to broader liabilities, a need to adjust our distribution channels for our products and services or otherwise change our business model, and could adversely impact our business.

***Violations of anti-bribery, anti-corruption and/or international trade laws to which we are subject could have a material adverse effect on our business operations, financial position and results of operations.***

We are subject to laws concerning our business operations and marketing activities in the U.S. and its territories where we conduct business. Further, we are subject to the U.S. Foreign Corrupt Practices Act, which generally prohibits companies and their intermediaries from making improper payments to non-U.S. government officials for the purpose of obtaining or retaining business. We currently only operate in the U.S. and its territories. However, in the future we may conduct business outside of

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

the U.S. and operate in parts of the world that experienced governmental corruption to some degree and, in certain circumstances, strict compliance with anti-bribery laws may conflict with local customs and practices. In addition, due to the level of regulation in our industry, our entry into new jurisdictions through internal growth or acquisitions requires substantial government contact where norms can differ from U.S. standards. Additionally, we regularly interact with domestic municipalities and municipal-owned centralized electric utilities. We will consider our interactions with these domestic governmental bodies when designing our policies and procedures and conducting training designed to facilitate compliance with domestic and international anti-bribery laws. Although we believe these policies and procedures will mitigate the risk of violations of such laws, our employees, dealers and agents may take actions in violation of our policies and anti-bribery laws. Any such violation, even if prohibited by our policies, could subject us to criminal or civil penalties or other sanctions, which could have a material adverse effect on our business, financial condition, cash flows and reputation.

***Violations of export control and/or economic sanctions laws and regulations to which we are subject could have a material adverse effect on our business operations, financial position and results of operations.***

Our products may be subject to export control regulations, including the Export Administration Regulations administered by the U.S. Department of Commerce's Bureau of Industry and Security. We are also subject to foreign assets control and economic sanctions regulations administered by the U.S. Department of the Treasury's Office of Foreign Assets Control, which restrict or prohibit our ability to transact with certain foreign countries, individuals and entities. We currently only operate in the U.S. and its territories. However, export control regulations may restrict our ability to exchange technical information with foreign manufacturers and suppliers and economic sanctions regulations may restrict our ability to source from certain suppliers. In addition, in the future we may conduct business outside of the U.S. We will consider these scenarios when designing our policies and procedures and conducting training designed to facilitate compliance with U.S. export control and economic sanctions laws and regulations. Although we believe these policies and procedures will mitigate the risk of violations of such laws, our employees, dealers and agents may take actions in violation of our policies or these laws. Any such violation, even if prohibited by our policies, could subject us to criminal or civil penalties or other sanctions, which could have a material adverse effect on our business, financial condition, cash flows and reputation.

***Our business is subject to complex and evolving privacy and data protection laws. Many of these laws and regulations are subject to change and uncertain interpretation and could result in claims, increased cost of operations or otherwise harm our business.***

Consumer personal privacy and data security have become significant issues and the subject of rapidly evolving regulation. Furthermore, federal, state and local government bodies or agencies have in the past adopted, and may in the future adopt, more laws and regulations affecting data privacy. For example, the state of California enacted the California Consumer Privacy Act of 2018 ("CCPA") and California voters recently approved the California Privacy Rights Act ("CPRA"). The CCPA creates individual privacy rights for consumers and places increased privacy and security obligations on entities handling the personal data of consumers or households. The CCPA went into effect in January 2020 and it requires covered companies to provide new disclosures to California consumers, provides such consumers, business-to-business contacts and employees new ways to opt-out of certain sales of personal information, and allows for a new private right of action for data breaches. The CPRA modifies the CCPA and imposes additional data protection obligations on companies doing business in California, including additional consumer rights processes and opt outs for certain uses of sensitive data. The CPRA went into effect in January 2023 and it established a new California privacy regulator. The CCPA and the CPRA may significantly impact our business activities and require substantial compliance costs that adversely affect our business, operating results, prospects and financial condition. To date, we have not experienced substantial compliance costs in connection with fulfilling the requirements under the CCPA or CPRA. However, we cannot be certain that compliance costs will not increase in the future with respect to the CCPA and CPRA or any other recently passed consumer privacy regulation. Furthermore, if we expand to foreign markets we will be subject to additional privacy and data protection laws, such as the General Data Protection Regulation in the European Union.

Any inability to adequately address privacy and security concerns, even if unfounded, or comply with applicable privacy and data protection laws, regulations and policies, could result in additional cost and liability to us, damage our reputation, inhibit sales and adversely affect our business. Furthermore, the costs of compliance with, and other burdens imposed by, the laws, regulations and policies that are applicable to our business may limit the use and adoption of, and reduce the overall demand for, our solutions. If we are not able to adjust to changing laws, regulations and standards related to privacy or security, our business may be harmed.

***Our business is subject to consumer protection laws. Such laws and regulatory enforcement policies and priorities are subject to change that may negatively impact our business.***

We must comply with various international, federal, state, and local regulatory regimes, including those applicable to consumer credit transactions, leases, and marketing activities. These laws and regulations, including those applicable to consumer loans and their origination, are subject to change and modification by statute, administrative rules and orders, and judicial interpretation. As a result of infrequent or sparse interpretations, ambiguities in these laws and regulations may create uncertainty with respect to what type of conduct is permitted or restricted under such laws and regulations. Regulators, such as the Federal Trade Commission and the Consumer Financial Protection Board, as well as state attorney generals and agencies, also can initiate inquiries into market participants, which can lead to investigations and, ultimately, enforcement actions. As a result, we are subject to a constantly evolving consumer protection and consumer finance regulatory environment that is difficult to predict and which may affect our business.

The laws to which we may be subject to include federal and state laws that prohibit unfair, deceptive or abusive business acts or practices (such as the Federal Trade Commission Act and the Dodd-Frank Act), regulate lease and loan disclosures and terms and conditions (such as the Truth-in-Lending Act and the Consumer Leasing Act), prohibit discrimination (such as the Equal Credit Opportunity Act), and provide additional protections for certain customers in the military (such as Servicemembers Civil Relief Act that provides additional protections for certain customers in the military. Our business is or may also be subject to federal and state laws that regulate consumer credit report information, data privacy, debt collection, electronic fund transfers, home improvement contracting and marketing activities (such as telemarketing, door-to-door sales, and e-mails).

While we have developed policies and procedures designed to assist in compliance with these laws and regulations, no assurance is given that our compliance policies and procedures will be effective. Failure to comply with these laws and with regulatory requirements applicable to our business could subject us to damages, revocation of licenses, class action lawsuits, administrative enforcement actions, civil and criminal liability, settlements, limits on offering certain products and services, changes in business practices, increased compliance costs, indemnification obligations to our capital providers, loan repurchase obligations and reputational damage which may harm our business, results of operations and financial condition.

***The highly regulated environment in which our capital providers operate could have an adverse effect on our business.***

We and our capital providers are subject to federal and state supervision and regulation. Federal and state regulation of the banking industry, credit unions and other types of capital providers, along with tax and accounting laws, regulations, rules and standards, may limit their operations significantly and control the methods by which they conduct business and when and how they are able to deploy their capital. These requirements may constrain our ability to enter funding program agreements with new capital providers or the ability of our existing capital providers to continue originating loans through our platform. In choosing whether and how to conduct business with us, current and prospective capital providers can be expected to take into account the legal, regulatory and supervisory regimes that apply to them, including potential changes in the application or interpretation of regulatory standards, licensing requirements or supervisory expectations. Regulators may elect to alter standards or the interpretation of the standards used to measure regulatory compliance or to determine the adequacy of liquidity, certain risk management or other operational practices for financial services companies in a manner that impacts capital providers' ability to originate loans through our platform. An inability for an individual or type of capital provider to originate loans through our platform could have an adverse effect on our business, financial condition and cash flows.

**Risks Related to Taxation**

***Our ability to use NOLs and tax credit carryforwards to offset future income taxes is subject to limitation and the amount of such carryforwards may be subject to challenge or reduction.***

As of December 31, 2022, we had approximately $1.2 billion of U.S. federal NOLs, a portion of which will begin to expire in 2032, and approximately $285.6 million of U.S. federal tax credit carryforwards, which will begin to expire in 2033. Utilization of our NOLs and tax credit carryforwards depends on many factors, including having current or future taxable income, which cannot be assured. In addition, Section 382 of the Code generally imposes an annual limitation on the amount of NOLs that may be used to offset taxable income by a corporation that has undergone an "ownership change" (as determined under Section 382). An ownership change generally occurs if one or more stockholders (or groups of stockholders, including one or more groups of public stockholders) that are each deemed to own at least 5% of our stock increase their ownership percentage by more than 50 percentage points over their lowest ownership percentage during a rolling three-year period. Similar rules under Section 383 of the Code impose an annual limitation on the amount of tax credit carryforwards, including carryforwards of Section 48(a) ITCs, that may be used to offset U.S. federal income taxes.

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

We experienced an "ownership change" in August 2020 as defined by Sections 382 and 383 of the Code, which limits our future ability to utilize NOLs and tax credits generated before the "ownership change". However, these limitations do not prevent the use of our NOLs to offset certain built-in gains, including deemed gains with respect to our cost recovery deductions, recognized by us within five years after the ownership change with respect to assets held by us at the time of the ownership change, or the use of our tax credits to offset related tax liabilities, to the extent of our "net unrealized built-in gain" at the time of the ownership change. We have determined that, based upon the size of our net unrealized built-in gain at the time of our 2020 ownership change and our projected recognition of deemed built-in gains in the five years following the ownership change, there is no impact on the balances for deferred taxes or valuation allowance. Another "ownership change" could occur as a result of transactions that increase the ownership percentage of any of our 5% stockholders during a rolling three-year period, including redemptions of our stock, sales of our stock by other deemed 5% stockholders or issuances of stock by us, whether in additional public offerings or otherwise. If such another ownership change occurs, our ability to utilize NOLs and tax credit carryforwards may be subject to further limitation under Sections 382 and 383 of the Code. The application of the aforementioned limitations may cause U.S. federal income taxes to be paid by us earlier than they otherwise would be paid if such limitations were not in effect and could cause such NOLs and tax credit carryforwards to expire unused, in each case reducing or eliminating the benefit of such NOLs and tax credit carryforwards. To the extent we are not able to offset our future taxable income with our NOLs or offset future taxes with our tax credit carryforwards, this would adversely affect our operating results and cash flows if we have taxable income in the future. These same risks can arise in the context of state income and franchise tax given many states conform to federal law and rely on federal authority for determining state NOLs.

Furthermore, the IRS or other tax authorities could successfully challenge one or more tax positions we take, such as the classification of assets under the income tax depreciation rules or the characterization of expenses for income tax purposes, which could reduce the NOLs we generate and/or are able to use.

***Our tax positions are subject to challenge by the relevant tax authority.***

Our federal and state tax positions may be challenged by the relevant tax authority. The process and costs, including potential penalties for nonpayment of disputed amounts, of contesting such challenges, administratively or judicially, regardless of the merits, could be material. Future tax audits or challenges by tax authorities to our tax positions may result in a material increase in our estimated future income tax or other tax liabilities, which would negatively impact our financial condition.

For example, many of our solar energy systems are located in states or territories that exempt such assets from state, territorial and local sales and property taxes. We believe these solar energy systems are and should continue to be exempt from certain state, territorial and local sales and property taxes; however, some of our solar energy systems are located in certain jurisdictions where the applicability of these exemptions to solar energy systems is the subject of ongoing litigation and possible legislative change or else the jurisdiction's law is uncertain regarding the effect on property and sales tax exemptions of certain complex business reorganizations undergone by us and our subsidiaries. As such, some tax authorities could challenge the availability of these exemptions. If our solar energy systems are determined to be subject to state, territorial or local sales or property taxes, it could negatively impact our financial condition.

***Our ability to provide our solar service offerings to home and business owners on an economically viable basis depends in part on our ability to finance these solar energy systems with tax equity investors that depend on particular tax and other benefits.***

Historically, there have been a limited number of investors that generate sufficient profits and possess the requisite financial sophistication to benefit from the tax benefits our tax equity vehicles provide, and a lack of depth in this market may limit our ability to complete such tax equity financing. Potential investors seeking tax-advantaged financing must remain satisfied the structures we offer qualify for the tax benefits associated with solar energy systems available to these investors, which depends both on the investors' assessment of tax law and the absence of any unfavorable interpretations of that law. Changes in existing law and interpretations by the IRS and the courts could reduce the willingness of tax equity investors to invest in tax equity vehicles associated with these solar energy system investments or cause these investors to require a larger allocation of customer payments. We are not certain this type of financing will continue to be available to us as the legal and regulatory landscape may shift in a manner that reduces or eliminates the attractiveness of such financing opportunities. For example, the Section 48E ITC percentage will begin to phase down for projects that begin construction after (a) 2033 or (b) if later, the first year after the year in which the U.S. Treasury Department determines greenhouse gas emissions from the production of electricity in the U.S. are no more than 25% of 2022 levels. The IRA also added a new provision that allows taxpayers to transfer certain federal income tax credits that arise after 2022, such as the Section 48(a) ITC, to third parties for cash. It is unclear what effect the ability to transfer these tax credits will have on tax equity structures, although we expect the market for tax equity structures to continue for investors who will continue to value benefits that are not transferable, such as

------

accelerated depreciation. Additionally, we may be unable to identify investors interested in engaging in this type of financing with us. As of December 31, 2022, we have formed 25 tax equity vehicles to which investors such as banks and other large financial investors have committed to invest approximately $1.8 billion. The undrawn committed capital for these tax equity vehicles as of December 31, 2022 is approximately $210.5 million. We plan to continue to form new tax equity vehicles as long as existing tax law and regulations make such financing attractive. See "*—Risks Related to Regulations—Our business currently depends in part on the availability of rebates, tax credits and other financial incentives. The expiration, elimination or reduction of these rebates, credits or incentives or our ability to monetize them could adversely impact our business*".

The contractual terms in certain of our tax equity vehicle documents impose conditions on our ability to draw on financing commitments from the tax equity investors, including if an event occurs that could reasonably be expected to have a material adverse effect on the tax equity vehicle or on us. The terms and conditions of our tax equity vehicles can vary and may require us to alter our products, services or product mix. If we do not satisfy such conditions due to events related to our business or a specific tax equity vehicle or developments in our industry or otherwise, and as a result we are unable to draw on existing commitments, it could have a material adverse effect on our business, financial condition, results of operations and liquidity. In addition to our inability to draw on the investors' commitments, we may incur financial penalties for non-performance (including delays in the installation process and interconnection to the power grid of solar energy systems and other factors). Based on the terms of the tax equity vehicle agreements, we will either reimburse a portion of the tax equity investor's capital or pay the tax equity investor a non-performance fee.

***Under the terms of certain of our tax equity vehicles, we may be required to make payments to the tax equity investors if certain tax benefits allocated to such tax equity investors are not realized as expected. Our financial condition may be adversely impacted if a tax equity vehicle is required to make any tax-related payments.***

Our tax equity vehicles require that, prior to a date that is at least five years after the last project was placed in service, the tax equity investor receives substantially all the non-cash value attributable to the solar energy systems; however, we typically receive a majority of the cash distributions. In the event the tax equity investor has tax liability as a result of its investment and the cash distributions payable to the tax equity investor are not sufficient to pay such tax liability, the amount of distributions payable to us may be reduced. The amounts of potential tax liability (and the potential for a reduced distribution to us) depend on the tax benefits that accrue to such investors from the tax equity vehicles' activities and may be impacted by changes in tax law.

Additionally, we may have payment obligations to our tax equity investors under indemnity obligations contained in those financings. See "*—If the IRS or the U.S. Treasury Department makes a determination that the fair market value of our solar energy systems is materially lower than what we have reported in our tax equity vehicles' tax returns, we may have to pay significant amounts to our tax equity vehicles, our tax equity investors and/or the U.S. government. Such determinations could have a material adverse effect on our business and financial condition*" and "*—If our solar energy systems either cease to be qualifying property or undergo certain changes in ownership within five years of the applicable placed in service date, we may have to pay significant amounts to our tax equity vehicles, our tax equity investors and/or the U.S. government. Such recapture could have a material adverse effect on our business and financial condition*".

Due to uncertainties associated with estimating the timing and amounts of cash distributions and allocations of tax benefits to such investors, we cannot determine the potential impact on our cash flows under current or future arrangements. Any significant reductions in the cash we expect to receive from these structures could adversely affect our financial condition.

***Changes in tax law could adversely affect our business.***

U.S. tax law is always subject to change. For example, in August 2022, the U.S. enacted the IRA, which contains significant changes to U.S. tax law including, but not limited to, a corporate minimum tax and 1% excise tax on stock repurchases. Other potential changes to the Code include changes to the U.S. corporate income tax rate and provisions limiting or eliminating various deductions, credits or tax preferences. Interpretations of the Code and regulations promulgated by the IRS are likewise subject to change. As states elect to conform (or else have rolling conformity) to the Code, such interpretations and regulations (including those promulgated by state authorities) could likewise affect our state income and franchise tax obligations. Any future changes in tax law, including changes to U.S. federal, state, territorial or local tax law, could affect our tax position and adversely impact our business.

***If the IRS or the U.S. Treasury Department makes a determination that the fair market value of our solar energy systems is materially lower than what we have reported in our tax equity vehicles' tax returns, we may have to pay significant amounts***

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

***to our tax equity vehicles, our tax equity investors and/or the U.S. government. Such determinations could have a material adverse effect on our business and financial condition.***

The basis of our solar energy systems we report in our tax equity vehicles' tax returns to claim the Section 48(a) ITC or the Section 48E ITC is based on the appraised fair market value of our solar energy systems. The IRS continues to scrutinize fair market value determinations industry-wide. We are not aware of any IRS audits or results of audits related to our appraisals or fair market value determinations of any of our tax equity vehicles. If, as part of an examination, the IRS were to review the fair market value we used to establish our basis for claiming Section 48(a) ITCs or Section 48E ITCs and successfully assert the Section 48(a) ITCs or the Section 48E ITCs previously claimed should be reduced, we would owe certain of our tax equity vehicles or our tax equity investors an amount equal to the disallowed Section 48(a) ITCs or Section 48E ITCs attributable to each investor's share of the difference between the fair market value used to establish our basis for claiming Section 48(a) ITCs or Section 48E ITCs and the adjusted fair market value determined by the IRS, plus any costs and expenses associated with a challenge to that fair market value, plus a gross up to pay for additional taxes. We could also be subject to tax liabilities, including interest and penalties, based on our share of claimed Section 48(a) ITCs or Section 48E ITCs. To date, we have not been required to make such payments under any of our tax equity vehicles. We have obtained insurance coverage with respect to certain losses that may be incurred should the Section 48(a) ITCs or Section 48E ITCs previously claimed with respect to our tax equity vehicles be reduced. Any such losses could be outside the scope of these insurance policies or exceed insurance policy limits and we could incur unforeseen costs that could harm our business and financial condition.

***If our solar energy systems either cease to be qualifying property or undergo certain changes in ownership within five years of the applicable placed in service date, we may have to pay significant amounts to our tax equity vehicles, our tax equity investors and/or the U.S. government. Such recapture could have a material adverse effect on our business and financial condition.***

The Section 48(a) ITCs and the Section 48E ITCs are subject to recapture under the Code if a solar energy system either ceases to be qualifying property or undergoes certain changes in ownership within five years of its placed in service date. The amount of Section 48(a) ITCs or Section 48E ITCs subject to recapture decreases by 20% of the claimed amount on each anniversary of a solar energy system's placed in service date. If such a recapture event were to occur, we could owe certain of our tax equity vehicles or our tax equity investors an amount equal to such vehicles' or investors' share of the Section 48(a) ITCs or the Section 48E ITCs that were recaptured. We could also be subject to tax liabilities, including interest and penalties, based on our share of recaptured Section 48(a) ITCs or Section 48E ITCs. Any such recapture could have a material adverse effect on our business and financial condition.

**Risks Related to Our Common Stock**

***We do not intend to pay, and our credit facilities currently prohibit us from paying, cash dividends on our common stock and, consequently, your only opportunity to achieve a return on your investment is if the price of our common stock appreciates.***

We do not plan to declare dividends on shares of our common stock in the foreseeable future. Additionally, we are currently prohibited from making any cash dividends pursuant to the terms of certain of our credit facilities. Consequently, your only opportunity to achieve a return on your investment in us will be if you sell your common stock at a price greater than you paid for it. There is no guarantee the price of our common stock that will prevail in the market will ever exceed the price you paid for it.

***Ownership of our common stock by current stockholders is expected to remain significant.***

Due to their ownership percentages, certain key stockholders may have the ability to exercise significant influence over matters submitted to our stockholders for approval. This concentration of ownership may also have the effect of delaying or preventing a change of control of our company or discouraging others from making tender offers for our shares, which could prevent our stockholders from receiving an offer premium for their shares. So long as the key stockholders continue to own a significant amount of our common stock, they will continue to be able to strongly influence all matters requiring stockholder approval, regardless of whether or not other stockholders believe a potential transaction is in their own best interests. In any of these matters, the interests of the key stockholders may differ or conflict with the interests of our other stockholders. In addition, certain of the key stockholders may, from time to time, acquire interests in businesses that directly or indirectly compete with our business, as well as businesses that are significant existing or potential customers. Certain of the key stockholders may acquire or seek to acquire assets we seek to acquire and, as a result, those acquisition opportunities may not be available to us or may be more expensive for us to pursue.

***The price of our common stock is volatile and may decline in value.***

The market price of our common stock may be influenced by many factors, some of which are beyond our control, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;public reaction to our press releases, announcements and filings with the SEC;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;our operating and financial performance;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;fluctuations in broader securities market prices and volumes, particularly among securities of technology and solar companies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;changes in market valuations of similar companies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;departures of key personnel;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;commencement of or involvement in litigation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;variations in our quarterly results of operations or those of other technology and solar companies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;changes in general economic conditions, financial markets or the technology and solar industries;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;announcements by us or our competitors of significant acquisitions or other transactions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;changes in accounting standards, policies, guidance, interpretations or principles;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;speculation in the press or investment community;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;actions by our stockholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;the failure of securities analysts to cover our common stock or changes in their recommendations and estimates of our financial performance;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;future sales of our common stock, including by large stockholders, or perceptions that such sales might occur; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;the other factors described in these "*Risk Factors*".

***If we fail to comply with the reporting requirements under the Exchange Act or maintain adequate internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act, it could result in late or non-compliant filings or inaccurate financial reporting and have a negative impact on the price of our common stock or our business.***

Effective internal controls are necessary for us to provide timely, reliable financial reporting and prevent fraud. Our accounting predecessor was not a public company and was not required to comply with the reporting requirements of the Exchange Act, or with the standards adopted by the Public Company Accounting Oversight Board in compliance with the requirements of Section 404 of the Sarbanes-Oxley Act regarding internal controls over financial reporting. As a public company, we are required to report our financial results on the timeline and in the form prescribed by the Exchange Act and to evaluate and report on our internal control over financial reporting. This requires management to certify financial and other information in our quarterly and annual reports and provide an annual management report on the effectiveness of internal control over financial reporting.

We are required to disclose material changes made in our internal controls and procedures on a quarterly basis and annually review and report on, and our independent registered public accounting firm must attest to, the effectiveness of our internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act. Material weaknesses and significant deficiencies may exist when we report on the effectiveness of our internal control over financial reporting as required by reporting requirements under Section 404 of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act.

The process of documenting and further developing our internal controls to become compliant with Section 404 has taken a significant amount of time and effort to complete and required significant attention of management. We are continuing to improve our internal controls over financial reporting. We have expended, and anticipate we will continue to expend, significant resources in order to maintain and enhance existing effective disclosure controls and procedures and internal controls over financial reporting. Our current controls and any new controls we develop may become inadequate because of changes in conditions in our business. We may experience higher than anticipated operating expenses, as well as increased independent auditor and other fees and expenses during the implementation of these changes and thereafter.

***Certain of our directors have significant duties with, and spend significant time serving, entities that may compete with us in seeking business opportunities and, accordingly, may have conflicts of interest in allocating time or pursuing business opportunities.***

Certain of our directors, who are responsible for managing the direction of our operations and acquisition activities, hold positions of responsibility with other entities whose businesses are similar to our business. The existing positions held by these directors may give rise to fiduciary or other duties in conflict with the duties they owe to us. These directors may become aware of business opportunities that may be appropriate for presentation to us as well as to the other entities with which they are or may become affiliated. Due to these existing and potential future affiliations, they may present potential business opportunities

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

to other entities prior to presenting them to us, which could cause additional conflicts of interest. They may also decide certain opportunities are more appropriate for other entities with which they are affiliated and as a result, they may elect not to present those opportunities to us. These conflicts may not be resolved in our favor.

***Conflicts of interest could arise in the future between us, on the one hand, and any of our stockholders and its affiliates and affiliated funds and its and their current and future portfolio companies on the other hand, concerning, among other things, potential competitive business activities or business opportunities.***

Conflicts of interest could arise in the future between us, on the one hand, and any of our stockholders and its affiliates and affiliated funds and its and their current and future portfolio companies, on the other hand, concerning, among other things, potential competitive business activities or business opportunities. For example, certain of our existing investors and their affiliated funds may invest in companies that operate in the traditional energy industry and solar and other renewable industries. As a result, our existing investors and their affiliates' and affiliated funds' current and future portfolio companies they control may now, or in the future, directly or indirectly, compete with us for investment or business opportunities.

Our governing documents provide that our stockholders and their affiliates and affiliated funds are not restricted from owning assets or engaging in businesses that compete directly or indirectly with us and will not have any duty to refrain from engaging, directly or indirectly, in the same or similar business activities or lines of business as us, including those business activities or lines of business deemed to be competing with us, or doing business with any of our clients, customers or vendors. In particular, subject to the limitations of applicable law, our certificate of incorporation, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• permits stockholders or their affiliates and affiliated funds and our non-employee directors to conduct business that competes with us and to make investments in any kind of property in which we may make investments; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• provides that if any of our stockholders or any of its affiliates who is also one of our non-employee directors becomes aware of a potential business opportunity, transaction or other matter, they will have no duty to communicate or offer that opportunity to us.

Our stockholders or their affiliates or affiliated funds may become aware, from time to time, of certain business opportunities (such as acquisition opportunities) and may direct such opportunities to other businesses in which they have invested, in which case we may not become aware of or otherwise have the ability to pursue such opportunity. Further, such businesses may choose to compete with us for these opportunities, possibly causing these opportunities to not be available to us or causing them to be more expensive for us to pursue. In addition, our stockholders or their affiliates and affiliated funds may dispose of their interests in energy infrastructure or other renewable companies or other assets in the future, without any obligation to offer us the opportunity to purchase any of those assets. As a result, our renouncing our interest and expectancy in any business opportunity that may be from time to time presented to any of our stockholders or their affiliates and affiliated funds could adversely impact our business or prospects if attractive business opportunities are procured by such parties for their own benefit rather than for ours.

In any of these matters, the interests of our existing stockholders and their affiliates and affiliated funds may differ or conflict with the interests of our other shareholders. Any actual or perceived conflicts of interest with respect to the foregoing could have an adverse impact on the trading price of our common stock.

***Provisions of our charter documents and Delaware law may inhibit a takeover, which could limit the price investors might be willing to pay in the future for our common stock.***

Our charter documents authorize our Board to issue preferred stock without stockholder approval and, relatedly, may have the effect of delaying or preventing an acquisition of us or a merger in which we are not the surviving company and may otherwise prevent or slow changes in our Board and management. In addition, some provisions of our certificate of incorporation, amended and restated bylaws and stockholders' agreement could make it more difficult for a third party to acquire control of us, even if the change of control would be beneficial to our stockholders, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limitations on changes of control and business combinations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limitations on the removal of directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limitations on the ability of our stockholders to call special meetings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• establishing advance notice provisions for stockholder proposals and nominations for elections to the Board to be acted upon at meetings of stockholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• providing that the Board is expressly authorized to adopt, or to alter or repeal our bylaws; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• establishing advance notice and certain information requirements for nominations for election to our Board or for proposing matters that can be acted upon by stockholders at stockholder meetings.

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

These provisions could discourage an acquisition of us or other change in control transactions and thereby negatively affect the price that investors might be willing to pay in the future for our common stock.

***Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware and, to the extent enforceable, the federal district courts of the United States of America as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.***

Our amended and restated certificate of organization provides that, unless we consent in writing to the selection of an alternative forum, the sole and exclusive forum for (a) any derivative action or proceeding brought on our or our stockholders' behalf, (b) any action asserting a claim of breach of a fiduciary duty owed by any of our current or former directors, officers, employees, agents and stockholders to us or our stockholders, (c) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our amended and restated certificate of incorporation or our amended and restated bylaws, (d) any action as to which the Delaware General Corporation Law confers jurisdiction to the Court of Chancery of the State of Delaware, or (e) any other action asserting a claim that is governed by the internal affairs doctrine shall be the Court of Chancery of the State of Delaware. Our amended and restated certificate of incorporation also provides that, to the fullest extent permitted by applicable law, the federal district courts of the United States are the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act, subject to and contingent upon a final adjudication in the State of Delaware of the enforceability of such exclusive forum provision.

***Future sales of our common stock in the public market, or the perception that such sales may occur, could reduce our stock price, and any additional capital raised by us through the sale of equity or convertible securities may dilute your ownership in us.***

We may raise additional capital through the issuance of equity or debt in the future. In that event, the ownership of our existing stockholders would be diluted and the value of the stockholders' equity in common stock could be reduced. If we raise more equity capital from the sale of common stock, institutional or other investors may negotiate terms more favorable than the current prices of our common stock. If we issue debt securities, the holders of the debt would have a claim to our assets that would be prior to the rights of stockholders until the debt is paid. Interest on these debt securities would increase costs and could negatively impact operating results.

In accordance with Delaware law and the provisions of our charter documents, we may issue preferred stock that ranks senior in right of dividends, liquidation or voting to our common stock. The issuance by us of such preferred stock may (a) reduce or eliminate the amount of cash available for payment of dividends to our holders of common stock, (b) diminish the relative voting strength of the total shares of common stock outstanding as a class, or (c) subordinate the claims of our holders of common stock to our assets in the event of our liquidation. Our amended and restated Certificate of Incorporation does not provide stockholders the pre-emptive right to buy shares from us. As a result, stockholders will not have the automatic ability to avoid dilution in their percentage ownership of us.

We cannot predict the size of future issuances of our common stock or securities convertible into common stock or the effect, if any, that future issuances and sales of shares of our common stock will have on the market price of our common stock. Sales of substantial amounts of our common stock (including shares issued in connection with an acquisition), or the perception that such sales could occur, may adversely affect prevailing market prices of our common stock.

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

***The capped call transactions may affect the value of our common stock.***

The capped call transactions are expected generally to reduce the potential dilution to our common stock upon any conversion of notes and/or offset any cash payments we are required to make in excess of the principal amount of converted notes, as the case may be, with such reduction and/or offset subject to a cap. In connection with establishing their initial hedges of the capped call transactions, we expect the option counterparties or their respective affiliates to purchase shares of our common stock and/or enter into various derivative transactions with respect to our common stock concurrently with or shortly after the pricing of the Convertible Notes. This activity could increase (or reduce the size of any decrease in) the market price of our common stock at that time.

In addition, the option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to our common stock and/or purchasing or selling our common stock or other securities of ours in secondary market transactions prior to the maturity of the 0.25% convertible senior notes (and are likely to do so during the observation period for conversions of the 0.25% convertible senior notes following September 1, 2026 or following any repurchase of the 0.25% convertible senior notes by us and during the observation period for conversions of the 2.625% convertible senior notes following November 15, 2027 or following any repurchase of the 2.625% convertible senior notes by us). This activity could also cause or avoid an increase or a decrease in the market price of our common stock.

The potential effect, if any, of these transactions and activities on the market price of our common stock will depend in part on market conditions and cannot be ascertained at this time.

**General Risk Factors**

***We are exposed to the credit risk of our customers and payment delinquencies on our accounts receivable.***

Our customers purchase solar energy or lease solar energy systems from us pursuant to one of two types of long-term contracts: a PPA or a lease. The PPA and lease terms are typically for 20 or 25 years. In addition, under our loan agreements the customer finances the purchase of a solar energy system and we agree to operate and maintain the solar energy system throughout the term of the agreement. Our solar service agreements require the customer to make monthly payments to us throughout the term of the contract, unless prepaid. Because we have long-term, contractual relationships with our customers, we are subject to the credit risk of our customers and screen our customers based upon their credit rating in an attempt to mitigate the risk of customer default. As of December 31, 2022, the average FICO<sup>®</sup> score of our customers for whom we have a FICO<sup>®</sup> score was 739 at the time of signing the solar service agreement. The accuracy of independent third-party information provided to the credit reporting agency cannot be verified. A FICO<sup>®</sup> score purports only to be a measurement of the relative degree of risk a borrower represents to a lender, i.e., a borrower with a higher score may be less likely to default in payment than a borrower with a lower score.

As of December 31, 2022, approximately 0.9% of our customers were in default under their solar service agreements. However, as we grow our business, the risk of customer defaults may increase as credit scores are dynamic and may deteriorate over a 25-year period. During an economic downturn or during periods of rising inflation and interest rates, the risk of customer defaults may increase. In addition, our customers may assign their solar service agreements to other customers who have lower credit scores or we may enter into new solar service agreements in the future with customers who have lower credit scores than our current customers. In addition, future developments, including competition from other renewables, could decrease the attractiveness of our current contracts. Although our solar service agreements grant us the ability to terminate the agreement with the customer and repossess the defaulting customers' solar energy system in certain circumstances, enforcement of these rights under the solar service agreement may be difficult, expensive and time-consuming. If we experience increased customer defaults, our revenue and our ability to raise new investment funds could be adversely affected. If economic conditions worsen, certain of our customers may face liquidity concerns and may be unable to satisfy their payment obligations to us on a timely basis or at all, which could have a material adverse effect on our financial condition and results of operations.

***We are not able to insure against all potential risks and we may become subject to higher insurance premiums.***

We are exposed to numerous risks inherent in the operation of solar energy systems and energy storage systems, including equipment failure, manufacturing defects, natural disasters such as hurricanes, freezes, fires and earthquakes, terrorist attacks, sabotage, vandalism and environmental risks. Furthermore, components of our solar energy systems and energy storage systems, such as panels, inverters and batteries, could be damaged by severe weather, such as tsunamis, hurricanes, tornadoes, hailstorms or lightning. If our solar energy systems or energy storage systems are damaged in the event of a natural disaster beyond our control, losses could be outside the scope of insurance policies or exceed insurance policy limits and we could incur

------

unforeseen costs that could harm our business and financial condition. We may also incur significant additional costs in taking actions in preparation for, or in reaction to, such events.

Our insurance policies also cover legal and contractual liabilities arising out of bodily injury, personal injury or property damage to third parties and are subject to policy limits. We also maintain coverage for physical damage to our solar energy assets.

However, such policies do not cover all potential losses and coverage is not always available in the insurance market on commercially reasonable terms. In addition, we may have disagreements with our insurers on the amount of our recoverable damages and the insurance proceeds received for any loss of, or any damage to, any of our assets may be claimed by lenders under our financing arrangements or otherwise may not be sufficient to restore the loss or damage without a negative impact on our results of operations. Furthermore, the receipt of insurance proceeds may be delayed, requiring us to use cash or incur financing costs in the interim. To the extent we experience covered losses under our insurance policies, the limit of our coverage for potential losses may be decreased or the insurance rates we have to pay increased. Furthermore, the losses insured through commercial insurance are subject to the credit risk of those insurance companies. While we believe our commercial insurance providers are currently creditworthy, we cannot assure you such insurance companies will remain so in the future.

We may not be able to maintain or obtain insurance of the type and amount we desire at reasonable rates. The insurance coverage we do obtain may contain large deductibles or fail to cover certain risks or all potential losses. In addition, our insurance policies are subject to annual review by our insurers and may not be renewed on similar or favorable terms, including coverage, deductibles or premiums, or at all. If a significant accident or event occurs for which we are not fully insured or we suffer losses due to one or more of our insurance carriers defaulting on their obligations or contesting their coverage obligations, it could have a material adverse effect on our business, financial condition and results of operations.

***The loss of one or more members of our senior management or key employees may adversely affect our ability to implement our strategy.***

We depend on our experienced management team and the loss of one or more key executives could have a negative impact on our business. In particular, we are dependent on the services of our founder and CEO, William J. Berger. We also depend on our ability to retain and motivate key employees and attract qualified new employees. None of our key executives are bound by employment agreements for any specific term. We may be unable to replace key members of our management team and key employees if we lose their services. Integrating new employees into our team could prove disruptive to our operations, require substantial resources and management attention and ultimately prove unsuccessful. An inability to attract and retain sufficient managerial personnel who have critical industry experience and relationships could limit or delay our strategic efforts, which could have a material adverse effect on our business, financial condition and results of operations.

***Our inability to protect our intellectual property could adversely affect our business. We may also be subject to intellectual property rights claims by third parties, which are extremely costly to defend, could require us to pay significant damages and could limit our ability to use certain technologies.***

Any failure to protect our proprietary rights adequately could result in our competitors offering similar solar technology or energy storage services more quickly than anticipated, potentially resulting in the loss of some of our competitive advantage and a decrease in our revenue that would adversely affect our business prospects, financial condition and operating results. Our success depends, at least in part, on our ability to protect our core technology and intellectual property. We rely on intellectual property laws, primarily a combination of copyright and trade secret laws in the U.S., as well as license agreements and other contractual provisions, to protect our proprietary technology and brand. We cannot be certain our agreements and other contractual provisions will not be breached, including a breach involving the use or disclosure of our trade secrets or know-how, or that adequate remedies will be available in the event of any breach. In addition, our trade secrets may otherwise become known or lose trade secret protection.

We cannot be certain our products and our business do not or will not violate the intellectual property rights of a third party. Third parties, including our competitors, may own patents or other intellectual property rights that cover aspects of our technology or business methods. Such parties may claim we have misappropriated, misused, violated or infringed third-party intellectual property rights and if we gain greater recognition in the market, we face a higher risk of being the subject of claims we have violated others' intellectual property rights. Any claim we violated a third party's intellectual property rights, whether with or without merit, could be time-consuming, expensive to settle or litigate and could divert our management's attention and other resources, all of which could adversely affect our business, results of operations, financial condition and cash flows. If we do not successfully settle or defend an intellectual property claim, we could be liable for significant monetary damages and could be prohibited from continuing to use certain technology, business methods, content or brands. To avoid a prohibition, we

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

could seek a license from third parties, which could require us to pay significant royalties, increasing our operating expenses. If a license is not available at all or not available on commercially reasonable terms, we may be required to develop or license a non-violating alternative, either of which could adversely affect our business, results of operations, financial condition and cash flows.

***We currently use or plan to use software that is licensed under "open source", "free" or other similar licenses that may subject us to liability or require us to release the source code of our proprietary software to the public.***

We currently use open source software that is licensed under "open source", "free" or other similar licenses. Open source software is made available to the general public on an "as-is" basis under the terms of a non-negotiable license. If we fail to comply with these licenses, we may be subject to certain conditions, including requirements that we offer our services that incorporate the open source software for no cost, we make available source code for modifications or derivative works we create based upon incorporating or using the open source software and we license such modifications or alterations under the terms of the particular open source license. We do not plan to integrate our proprietary software with this open source software in ways that would require the release of the source code of our proprietary software to the public. However, our use and distribution of open source software may entail greater risks than use of third-party commercial software. Our authorized developers may contribute to this open source software community but they will be prohibited from providing any proprietary process or proprietarily developed source code of ours. Open source licensors generally do not provide warranties or other contractual protections regarding infringement claims or the quality of the code. In addition, if we combine our proprietary software with open source software in a certain manner, we could, under certain open source licenses, be required to release the source code of our proprietary software to the public. This would allow our competitors to create similar offerings with lower development effort and time. We may also face claims alleging noncompliance with open source license terms or infringement or misappropriation of proprietary software.

These claims could result in litigation, require us to purchase a costly license or require us to devote additional research and development resources to change our software, any of which would have a negative effect on our business and operating results. In addition, if the license terms for open source software that we use change, we may be forced to re-engineer our technology platform or incur additional costs.

Although we monitor our use of open source software to avoid subjecting our technology platform to unintended conditions, few courts have interpreted open source licenses and there is a risk these licenses could be construed in a way that could impose unanticipated conditions or restrictions on our business. We cannot guarantee we have incorporated open source software in our software in a manner that will not subject us to liability or in a manner consistent with our current policies and procedures.

***We may become involved in the future in legal proceedings that could adversely affect our business.***

We may, from time to time, be involved in litigation and claims, such as those related to employees, customers, our dealers or other third parties with whom we contract, including consumer claims and class action lawsuits. In the ordinary course of business, we have disputes with dealers and customers. In general, litigation claims or regulatory proceedings can be expensive and time consuming to bring or defend against, may result in the diversion of management attention and resources from our business and business goals and could result in injunctions or other equitable relief, settlements, penalties, fines or damages that could significantly affect our results of operations and the conduct of our business. It is impossible to predict with certainty whether any resulting liability would have a material adverse effect on our financial position, results of operations or cash flows.

***Our actual financial results may differ materially from any guidance we may publish from time to time.***

We may, from time to time, provide guidance regarding our future performance that represents our management's estimates as of the date such guidance is provided. Any such guidance would be based upon a number of assumptions with respect to future business decisions (some of which may change) and estimates, while presented with numerical specificity, are inherently subject to significant business, economic and competitive uncertainties and contingencies (many of which are beyond our control). Guidance is necessarily speculative in nature and it can be expected some or all the assumptions that inform such guidance will not materialize or will vary significantly from actual results. Our ability to meet any forward-looking guidance is impacted by a number of factors including, but not limited to, the number of our solar energy systems sold versus leased, changes in installation costs, the availability of additional financing on acceptable terms, changes in the retail prices of traditional utility-generated electricity, the availability of rebates, tax credits and other incentives, changes in policies and regulations including net metering and interconnection limits or caps, the availability of solar panels, inverters, batteries and other raw materials, as well as the other risks to our business described in this *"Risk Factors"* section. Accordingly, our

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

guidance is only an estimate of what management believes is realizable as of the date such guidance is provided. Actual results may vary from such guidance and the variations may be material. Investors should also recognize the reliability of any forecasted financial data diminishes the farther into the future the data is forecast. In light of the foregoing, investors should not place undue reliance on our financial guidance and should carefully consider any guidance we may publish in context.

***If we are unable to make acquisitions on economically acceptable terms, our future growth could be limited, and any acquisitions we may make may reduce, rather than increase, our cash flows.***

We may make acquisitions of solar energy systems, energy storage systems and related businesses and joint ventures. The consummation and timing of any future acquisitions will depend upon, among other things, whether we are able to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• identify attractive acquisition candidates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• negotiate acceptable purchase agreements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• obtain any required governmental or third party consents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• obtain financing for these acquisitions on economically acceptable terms, which may be more difficult at times when the capital markets are less accessible; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• outbid any competing bidders.

Additionally, any acquisition involves potential risks, including, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• mistaken assumptions about assets, revenues and costs of the acquired company, including synergies and potential growth;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an inability to secure adequate customer commitments to use the acquired systems or facilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an inability to successfully integrate the assets or businesses we acquire;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• coordinating geographically disparate organizations, systems and facilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the assumption of unknown liabilities for which we are not indemnified or for which our indemnity is inadequate;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• mistaken assumptions about the acquired company's suppliers or dealers or other vendors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the diversion of management's and employees' attention from other business concerns;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• unforeseen difficulties operating in new geographic areas and business lines;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• customer or key employee losses at the acquired business; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• poor quality assets or installation.

If we consummate any future acquisitions, our capitalization, results of operations and future growth may change significantly and our stockholders will not have the opportunity to evaluate the economic, financial and other relevant information we will consider in deciding to engage in these future acquisitions, which may not improve our results of operations or cash flow to the extent we projected.

**Item 1B. Unresolved Staff Comments.**

Not applicable.

**Item 2. Properties.**

Our corporate headquarters is in Houston, Texas, where we occupy approximately 73,800 square feet of office space pursuant to an operating lease that expires in July 2029. We lease additional offices in Houston, Guam, California, Florida, Nevada, Mississippi, New York and Puerto Rico, but do not own any real property. We intend to procure additional space in the future as we continue to add employees and expand geographically. We believe our facilities are adequate and suitable for our current needs and, should it be needed, suitable additional or alternative space will be available to accommodate our operations.

**Item 3. Legal Proceedings.**

Although we may, from time to time, be involved in litigation, claims and government proceedings arising in the ordinary course of business, we are not a party to any litigation or governmental or other proceeding we believe will have a material adverse impact on our financial position, results of operations or liquidity. In the ordinary course of business, we have disputes with dealers and customers. In general, litigation claims or regulatory proceedings can be expensive and time consuming to bring or defend against, may result in the diversion of management attention and resources from our business and business goals and could result in settlement or damages that could significantly affect financial results and the conduct of our business.

In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this Annual Report on Form 10-K may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.*

**Company Overview**

We are a leading EaaS provider, serving over 279,000 customers in more than 45 U.S. states and territories. Our goal is to be the source of clean, affordable and reliable energy with a simple mission: to power energy independence so home and business owners have the freedom to live life uninterrupted. We were founded to deliver customers a better energy service at a better price; and, through our energy service offerings, we are disrupting the traditional energy landscape and the way the 21st century customer generates and consumes electricity.

We have a differentiated dealer model in which we partner with local dealers who originate, design and install our customers' solar energy systems, energy storage systems and related products and services on our behalf. Our focus on our dealer model enables us to leverage our dealers' specialized knowledge, connections and experience in local markets to drive customer origination while providing our dealers with access to high quality products at competitive prices, as well as technical oversight and expertise. We believe this structure provides operational flexibility, reduces exposure to labor shortages and lowers fixed costs relative to our peers, furthering our competitive advantage.

We offer customers products to power their homes and businesses with affordable solar energy and related products and services. We are able to offer savings compared to utility-based retail rates with little to no up-front expense to the customer in conjunction with solar and solar plus energy storage, and, in the case of the latter, are able to also provide energy resiliency. Our solar service agreements typically take the form of a lease, PPA, loan or cash purchase; however, we also offer service plans for systems we did not originate. We make it possible in some states for a customer to obtain a new roof and other ancillary products as part of their solar loan. We also allow customers originated through our homebuilder channel the option of purchasing the system when the customer closes on the purchase of a new home. The initial term of our solar service agreements is typically between 10 and 25 years. Service is an integral part of our agreements and includes operations and maintenance, monitoring, repairs and replacements, equipment upgrades, on-site power optimization for the customer (for both supply and demand), the ability to efficiently switch power sources among the solar panel, grid and energy storage system, as appropriate, and diagnostics. During the life of the contract, we have the opportunity to integrate related and evolving servicing and monitoring technologies to upgrade the flexibility and reduce the cost of our customers' energy supply.

In the case of leases and PPAs, we also currently receive tax benefits and other incentives from federal, state and local governments, a portion of which we finance through tax equity, non-recourse debt structures and hedging arrangements in order to fund our upfront costs, overhead and growth investments. We have an established track record of attracting capital from diverse sources. From our inception through December 31, 2022, we have raised more than $11.8 billion in total capital commitments from equity, debt and tax equity investors.

In addition to providing ongoing service as a standard component of our solar service agreements, we also offer ongoing energy services to customers who purchased their solar energy system through third parties. Under these arrangements, we agree to provide monitoring, maintenance and repair services to these customers for the life of the service contract they sign with us. In addition, we offer one-time repair services to customers who purchased their solar energy systems through third parties. We also offer complimentary products to our agreements as well as non-solar financing. Specifically, our offerings include a non-solar loan program enabling customers to finance the purchase of products independent of a solar energy system or energy storage system. We believe the quality and scope of our comprehensive energy service offerings, whether to customers that obtained their solar energy system through us or through another party, is a key differentiator between us and our competitors.

In April 2021, we acquired SunStreet, Lennar's residential solar platform that focuses primarily on solar energy systems and energy storage systems for homebuilders. In connection with that acquisition, we entered into an agreement pursuant to

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

which we would be the exclusive solar and storage provider for Lennar's new home communities with solar across the U.S. for a period of four years. We believe the acquisition provides a new strategic path to further scale our solar business, reduces customer acquisition costs, provides a multi-year supply of sites through the development of new solar communities and allows us to pursue the development of clean and resilient microgrids across the U.S.

We also enter into leases with third-party owners of pools of solar energy systems to receive such third party's interest in those systems. In connection therewith, we assume the related customer PPA and lease obligations, entitling us to future customer cash flows as well as certain credits, rebates and incentives (including SRECs) under those agreements, in exchange for a lease payment, whether upfront or over time, to the third-party owner, which may be made in the form of cash or shares of our common stock. We believe such arrangements enhance our long-term contracted cash flows and are complementary to our overall business model.

We commenced operations in January 2013 and began providing solar energy services under our first solar energy system in April 2013. Since then, our brand, innovation and focused execution have driven significant, rapid growth in our market share and in the number of customers on our platform. We operate one of the largest residential fleets of solar energy systems in the U.S., comprising more than 1,627 megawatts of generation capacity and serving over 279,000 customers.

**Recent Developments**

***Financing Transactions***

In October 2022, a tax equity investor increased its capital commitment from approximately $25.0 million to approximately $75.0 million. In October 2022, we admitted a tax equity investor with a total capital commitment of approximately $30.0 million. In November 2022, we admitted a tax equity investor with a total capital commitment of approximately $41.0 million. In December 2022, we admitted three tax equity investors with a total capital commitment of approximately $239.0 million. See "*—Liquidity and Capital Resources—Financing Arrangements—Tax Equity Fund Commitments*" below.

In October 2022, the revolving credit facility by and among Sunnova TEP Holdings, LLC ("TEPH"), Credit Suisse AG, New York Branch, as administrative agent, and the lenders party thereto, was amended to, among other things, (a) increase the aggregate commitment amount from $564.7 million to $600.0 million and (b) increase the uncommitted maximum facility amount from $639.7 million to $689.7 million. In November 2022, the revolving credit facility by and among Sunnova Asset Portfolio 8, LLC ("AP8"), Banco Popular de Puerto Rico, as agent, and the lenders party thereto, was amended to, among other things, (a) increase the aggregate commitment amount from $60.0 million to $75.0 million, (b) extend the facility maturity date from September 2023 to September 2024, (c) add provisions to permit AP8 to acquire and own managing members of financing funds and related covenants regarding the ownership of such managing members of financing funds, (d) add the ability to borrow against solar assets, including amending the definition of "Borrowing Base" and related provisions and covenants to account for solar assets, (e) amend the eligibility criteria, concentration limits and amortization events for solar loans and the addition of solar assets, (f) replace the London interbank offered rate ("LIBOR") with Term SOFR (as defined by such revolving credit facility), (g) amend the interest rate on borrowings to an annual rate of Term SOFR (as defined by such revolving credit facility) plus 0.03, with interest payments being due quarterly and (h) include certain provisions addressing grid services revenue, service incentives, service incentives rebates and related matters. See "*—Liquidity and Capital Resources—Financing Arrangements—Warehouse and Other Debt Financings*" below.

In November 2022, one of our subsidiaries issued $103.4 million in aggregate principal amount of Series 2022-C Class A solar loan-backed notes, $80.6 million in aggregate principal amount of Series 2022-C Class B solar loan-backed notes and $51.7 million in aggregate principal amount of Series 2022-C Class C solar loan-backed notes (collectively, the "HELX Notes") with a maturity date of November 2049. The HELX Notes bear interest at an annual rate of 5.30%, 5.60% and 6.00% for the Class A, Class B and Class C notes, respectively. See "*—Liquidity and Capital Resources—Financing Arrangements—Securitizations*" below.

**Securitizations**

As a source of long-term financing, we securitize qualifying solar energy systems, energy storage systems and related solar service agreements into special purpose entities who issue solar asset-backed and solar loan-backed notes to institutional investors. We also securitize the cash flows generated by the membership interests in certain of our indirect, wholly-owned subsidiaries that are the managing member of a tax equity fund that owns a pool of solar energy systems, energy storage systems and related solar service agreements that were originated by one of our wholly-owned subsidiaries. For projects that begin construction after December 31, 2024, the Section 48(a) ITC will be replaced with the Section 48E ITC. We do not

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

securitize the Section 48(a) ITC incentives, and currently do not plan to securitize any Section 48E ITC incentives, associated with the solar energy systems and energy storage systems as part of these arrangements. We use the cash flows these solar energy systems and energy storage systems generate to service the monthly, quarterly or semi-annual principal and interest payments on the notes and satisfy the expenses and reserve requirements of the special purpose entities, with any remaining cash distributed to their sole members, who are typically our indirect wholly-owned subsidiaries. In connection with these securitizations, certain of our affiliates receive a fee for managing and servicing the solar energy systems and energy storage systems pursuant to management, servicing, facility administration and asset management agreements. The special purpose entities are also typically required to maintain a liquidity reserve account and a reserve account for equipment replacements and, in certain cases, reserve accounts for financing fund purchase option/withdrawal right exercises or storage system replacement for the benefit of the holders under the applicable series of notes, each of which are funded from initial deposits or cash flows to the levels specified therein. The creditors of these special purpose entities have no recourse to our other assets except as expressly set forth in the terms of the notes. From our inception through December 31, 2022, we have issued $3.6 billion in solar asset-backed and solar loan-backed notes.

**Tax Equity Funds**

Our ability to offer long-term solar service agreements depends in part on our ability to finance the installation of the solar energy systems and energy storage systems by co-investing with tax equity investors, such as large banks who value the resulting customer receivables and Section 48(a) ITCs or, in the future, Section 48E ITCs, accelerated tax depreciation and other incentives related to the solar energy systems and energy storage systems, primarily through structured investments known as "tax equity". Tax equity investments are generally structured as non-recourse project financings known as "tax equity funds". In the context of distributed generation solar energy, tax equity investors make contributions upfront or in stages based on milestones in exchange for a share of the tax attributes and cash flows emanating from an underlying portfolio of solar energy systems and energy storage systems. In these tax equity funds, the U.S. federal tax attributes offset taxes that otherwise would have been payable on the investors' other operations. The terms and conditions of each tax equity fund vary significantly by investor and by fund. We continue to negotiate with potential investors to create additional tax equity funds.

In general, our tax equity funds are structured using the "partnership flip" structure. Under partnership flip structures, we and our tax equity investors contribute cash into a partnership. The partnership uses this cash to acquire long-term solar service agreements, solar energy systems and energy storage systems developed by us and sells energy from such solar energy systems and energy storage systems, as applicable, to customers or directly leases the solar energy systems and energy storage systems, as applicable, to customers. We assign these solar service agreements, solar energy systems, energy storage systems and related incentives to our tax equity funds in accordance with the criteria of the specific funds. Upon such assignment and the satisfaction of certain conditions precedent, we are able to draw down on the tax equity fund commitments. The conditions precedent to funding vary across our tax equity funds but generally require that we have entered into a solar service agreement with the customer, the customer meets certain credit criteria, the solar energy system is expected to be eligible for the Section 48(a) ITC or the Section 48E ITC, as applicable, we have a recent appraisal from an independent appraiser establishing the fair market value of the solar energy system and the property is in an approved state or territory. Certain tax equity investors agree to receive a minimum target rate of return, typically on an after-tax basis, which varies by tax equity fund. Prior to receiving a contractual rate of return or a date specified in the contractual arrangements, the tax equity investor receives substantially all of the non-cash value attributable to the solar energy systems and energy storage systems, which includes accelerated depreciation and Section 48(a) ITCs or Section 48E ITCs, as applicable; however, we typically receive a majority of the cash distributions, which are typically paid quarterly. After the tax equity investor receives its contractual rate of return or after a specified date, we receive substantially all of the cash and tax allocations.

We have determined we are the primary beneficiary in these tax equity funds for accounting purposes. Accordingly, we consolidate the assets and liabilities and operating results of these partnerships in our consolidated financial statements. We recognize the tax equity investors' share of the net assets of the tax equity funds as redeemable noncontrolling interests and noncontrolling interests in our consolidated balance sheets. The income or loss allocations reflected in our consolidated statements of operations may create significant volatility in our reported results of operations, including potentially changing net loss attributable to stockholders to net income attributable to stockholders, or vice versa, from quarter to quarter.

We typically have an option to acquire, and our tax equity investors may have an option to withdraw and require us to purchase, all the equity interests our tax equity investor holds in the tax equity funds starting approximately five years after the last solar energy system in the applicable tax equity fund is operational. If we or our tax equity investors exercise this option, we are typically required to pay at least the fair market value of the tax equity investor's equity interest and, in certain cases, a contractual minimum amount. From our inception through December 31, 2022, we have received commitments of approximately $1.8 billion through the use of tax equity funds, of which an aggregate of $1.5 billion has been funded and $210.5 million remains available for use.

**Key Financial and Operational Metrics**

We regularly review a number of metrics, including the following key operational and financial metrics, to evaluate our business, measure our performance, identify trends affecting our business, formulate our financial projections and make strategic decisions.

*Number of Customers*. We define number of customers to include every unique premises on which a Sunnova product is installed or on which Sunnova is obligated to perform services for a counterparty. We track the total number of customers as an indicator of our historical growth and our rate of growth from period to period.

*Weighted Average Number of Systems.* We calculate the weighted average number of systems based on the number of months a customer and any additional service obligation related to a solar energy system is in-service during a given measurement period. The weighted average number of systems reflects the number of systems at the beginning of a period, plus the total number of new systems added in the period adjusted by a factor that accounts for the partial period nature of those new systems. For purposes of this calculation, we assume all new systems added during a month were added in the middle of that month. The number of systems for any end of period will exceed the number of customers, as defined above, for that same end of period as we are also including any additional services and/or contracts a customer or third party executed for the additional work for the same residence or business. We track the weighted average system count in order to accurately reflect the contribution of the appropriate number of systems to key financial metrics over the measurement period.

*Adjusted EBITDA.* We define Adjusted EBITDA as net income (loss) plus net interest expense, depreciation and amortization expense, income tax expense, financing deal costs, natural disaster losses and related charges, net, losses on extinguishment of long-term debt, realized and unrealized gains and losses on fair value instruments and equity securities, amortization of payments to dealers for exclusivity and other bonus arrangements, legal settlements and excluding the effect of certain non-recurring items we do not consider to be indicative of our ongoing operating performance such as, but not limited to, costs of our initial public offering ("IPO"), acquisition costs, losses on unenforceable contracts, indemnification payments to tax equity investors and other non-cash items such as non-cash compensation expense, asset retirement obligation ("ARO") accretion expense, provision for current expected credit losses and non-cash inventory impairments.

Adjusted EBITDA is a non-GAAP financial measure we use as a performance measure. We believe investors and securities analysts also use Adjusted EBITDA in evaluating our operating performance. This measurement is not recognized in accordance with accounting principles generally accepted in the United States of America ("GAAP") and should not be viewed as an alternative to GAAP measures of performance. The GAAP measure most directly comparable to Adjusted EBITDA is net income (loss). The presentation of Adjusted EBITDA should not be construed to suggest our future results will be unaffected by non-cash or non-recurring items. In addition, our calculation of Adjusted EBITDA is not necessarily comparable to Adjusted EBITDA as calculated by other companies.

We believe Adjusted EBITDA is useful to management, investors and analysts in providing a measure of core financial performance adjusted to allow for comparisons of results of operations across reporting periods on a consistent basis. These adjustments are intended to exclude items that are not indicative of the ongoing operating performance of the business. Adjusted EBITDA is also used by our management for internal planning purposes, including our consolidated operating budget, and by our board of directors in setting performance-based compensation targets. Adjusted EBITDA should not be considered an alternative to but viewed in conjunction with GAAP results, as we believe it provides a more complete understanding of ongoing business performance and trends than GAAP measures alone. Adjusted EBITDA has limitations as an analytical tool,

and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP.

*Interest Income and Principal Payments from Customer Notes Receivable.* Under our loan agreements, the customer obtains financing for the purchase of a solar energy system from us and we agree to operate and maintain the solar energy system throughout the duration of the agreement. Pursuant to the terms of the loan agreement, the customer makes scheduled principal and interest payments to us and has the option to prepay principal at any time in part or in full. Whereas we typically recognize payments from customers under our leases and PPAs as revenue, we recognize payments received from customers under our loan agreements (a) as interest income, to the extent attributable to earned interest on the contract that financed the customer's purchase of the solar energy system; (b) as a reduction of a note receivable on the balance sheet, to the extent attributable to a return of principal (whether scheduled or prepaid) on the contract that financed the customer's purchase of the solar energy system; and (c) as revenue, to the extent attributable to payments for operations and maintenance services provided by us.

While Adjusted EBITDA effectively captures the operating performance of our leases and PPAs, it only reflects the service portion of the operating performance under our loan agreements. We do not consider our types of solar service agreements differently when evaluating our operating performance. In order to present a measure of operating performance that provides comparability without regard to the different accounting treatment among our three types of solar service agreements, we consider interest income from customer notes receivable and principal proceeds from customer notes receivable, net of related revenue, as key performance metrics. We believe these two metrics provide a more meaningful and uniform method of analyzing our operating performance when viewed in light of our other key performance metrics across the three primary types of solar service agreements.

*Adjusted Operating Expense.* We define Adjusted Operating Expense as total operating expense less depreciation and amortization expense, financing deal costs, natural disaster losses and related charges, net, amortization of payments to dealers for exclusivity and other bonus arrangements, legal settlements, direct sales costs, cost of revenue related to cash sales, cost of revenue related to inventory sales, unrealized gains and losses on fair value instruments and excluding the effect of certain non-recurring items we do not consider to be indicative of our ongoing operating performance such as, but not limited to, costs of our IPO, acquisition costs, losses on unenforceable contracts, indemnification payments to tax equity investors and other non-cash items such as non-cash compensation expense, ARO accretion expense, provision for current expected credit losses and non-cash inventory impairments. Adjusted Operating Expense is a non-GAAP financial measure we use as a performance measure. We believe investors and securities analysts will also use Adjusted Operating Expense in evaluating our performance. This measurement is not recognized in accordance with GAAP and should not be viewed as an alternative to GAAP measures of performance. The GAAP measure most directly comparable to Adjusted Operating Expense is total operating expense. We believe Adjusted Operating Expense is a supplemental financial measure useful to management, analysts, investors, lenders and rating agencies as an indicator of the efficiency of our operations between reporting periods. Adjusted Operating Expense should not be considered an alternative to but viewed in conjunction with GAAP total operating expense, as we believe it provides a more complete understanding of our performance than GAAP measures alone. Adjusted Operating Expense has limitations as an analytical tool and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP, including total operating expense.

We use per system metrics, including Adjusted Operating Expense per weighted average system, as an additional way to evaluate our performance. Specifically, we consider the change in this metric from period to period as a way to evaluate our performance in the context of changes we experience in the overall customer base. While the Adjusted Operating Expense figure provides a valuable indicator of our overall performance, evaluating this metric on a per system basis allows for further nuanced understanding by management, investors and analysts of the financial impact of each additional system.

*Estimated Gross Contracted Customer Value*. We calculate estimated gross contracted customer value as defined below. We believe estimated gross contracted customer value can serve as a useful tool for investors and analysts in comparing the remaining value of our customer contracts to that of our peers.

Estimated gross contracted customer value as of a specific measurement date represents the sum of the present value of the remaining estimated future net cash flows we expect to receive from existing customers during the initial contract term of our leases and PPAs, which are typically 25 years in length, plus the present value of future net cash flows we expect to receive from the sale of related SRECs, either under existing contracts or in future sales, plus the cash flows we expect to receive from energy services programs such as grid services, plus the carrying value of outstanding customer loans on our balance sheet. From these aggregate estimated initial cash flows, we subtract the present value of estimated net cash distributions to redeemable noncontrolling interests and noncontrolling interests and estimated operating, maintenance and administrative expenses associated with the solar service agreements. These estimated future cash flows reflect the projected monthly customer payments over the life of our solar service agreements and depend on various factors including but not limited to solar service agreement type, contracted rates, expected sun hours and the projected production capacity of the solar equipment installed. For the purpose of calculating this metric, we discount all future cash flows at 6%.

The anticipated operating, maintenance and administrative expenses included in the calculation of estimated gross contracted customer value include, among other things, expenses related to accounting, reporting, audit, insurance, maintenance and repairs. In the aggregate, we estimate these expenses are $20 per kilowatt per year initially, with 2% annual increases for inflation, and an additional $81 per year non-escalating expense included for energy storage systems. We do not include maintenance and repair costs for inverters and similar equipment as those are largely covered by the applicable product and dealer warranties for the life of the product, but we do include additional cost for energy storage systems, which are only covered by a 10-year warranty. Expected distributions to tax equity investors vary among the different tax equity funds and are based on individual tax equity fund contract provisions.

Estimated gross contracted customer value is forecasted as of a specific date. It is forward-looking and we use judgment in developing the assumptions used to calculate it. Factors that could impact estimated gross contracted customer value include, but are not limited to, customer payment defaults, or declines in utility rates or early termination of a contract in certain

circumstances, including prior to installation. The following table presents the calculation of estimated gross contracted customer value as of December 31, 2022 and 2021, calculated using a 6% discount rate.

*Sensitivity Analysis*. The calculation of estimated gross contracted customer value and associated operational metrics requires us to make a number of assumptions regarding future revenues and costs which may not prove accurate. Accordingly, we present below a sensitivity analysis with a range of assumptions. We consider a discount rate of 6% to be appropriate based on recent transactions that demonstrate a portfolio of solar service agreements is an asset class that can be securitized successfully on a long-term basis with a weighted-average coupon of less than 6%. We also present these metrics with a discount rate of 6% based on industry practice. The appropriate discount rate for these estimates may change in the future due to the level of inflation, rising interest rates, our cost of capital and consumer demand for solar energy systems. In addition, the table below provides a range of estimated gross contracted customer value amounts if different cumulative customer loss rate assumptions were used. We are presenting this information for illustrative purposes only and as a comparison to information published by our peers.

**Significant Factors and Trends Affecting Our Business**

Our results of operations and our ability to grow our business over time could be impacted by a number of factors and trends that affect our industry generally, as well as new offerings of services and products we may acquire or seek to acquire in the future. Additionally, our business is concentrated in certain markets, putting us at risk of region-specific disruptions such as adverse economic, regulatory, political, weather and other conditions. See "*Item 1A. Risk Factors*" for further discussion of risks affecting our business.

***Financing Availability.*** Our future growth depends, in significant part, on our ability to raise capital from third-party investors on competitive terms to help finance the origination of our solar energy systems under our solar service agreements. We have historically used debt, such as convertible senior notes, asset-backed and loan-backed securitizations and warehouse facilities, tax equity, preferred equity and other financing strategies to help fund our operations. From our inception through December 31, 2022, we have raised more than $11.8 billion in total capital commitments from equity, debt and tax equity investors. With respect to tax equity, there are a limited number of potential tax equity investors, and the competition for this investment capital is intense. The principal tax credit on which tax equity investors in our industry rely is the Section 48(a) ITC. The amount for the Section 48(a) ITC was equal to 30% of the basis of eligible solar property that began construction before 2020 if placed in service before 2022. The Section 48(a) ITC percentage decreased to 26% for eligible solar property that began construction during 2020 or 2021 if the property is placed into service before 2022. Under the IRA, which was enacted in August 2022, for eligible solar property that begins construction before 2025, the Section 48(a) ITC percentage will be no less than 30% provided (a) the project satisfies certain labor and apprenticeship requirements, (b) the project has a maximum net output of less than one megawatt (as measured in alternating current) or (c) the project begins construction prior to January 29, 2023. If no criterion is satisfied, the base amount of the Section 48(a) ITC will be equal to 6%. In addition, the Section 48(a) ITC will be replaced by the Section 48E ITC for eligible solar property that begins construction after 2024, and the Section 48E ITC percentage will be the same as the percentage for the Section 48(a) ITC and subject to the same requirements in order to receive the full benefit. The Section 48E ITC percentage will begin to phase down for projects that begin construction after (a) 2033 or (b) if later, the first year after the year in which the U.S. Department of Treasury determines greenhouse gas emissions from the production of electricity in the United States are no more than 25% of 2022 levels. We believe our solar energy systems generally will not be subject to the labor and apprenticeship requirements due to the maximum net output of most of our solar energy systems. In addition, the IRA added a new provision that allows taxpayers to transfer certain federal income tax credits that arise after 2022, such as the Section 48(a) ITC, to third parties for cash. It is unclear what effect the ability to

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

transfer Section 48(a) ITCs will have on tax equity structures, although we expect the market for tax equity structures to continue for investors who will continue to value benefits that are not transferable, such as accelerated depreciation. We are continuing to evaluate the overall impact and applicability of the IRA to our ability to raise capital from third-party investors.

Our ability to raise capital from third-party investors is also affected by general economic conditions, the state of the capital markets, inflation levels and concerns about our industry or business. Specifically, interest rates remain subject to volatility that may result from action taken by the Federal Reserve. Recent data have suggested inflationary pressures may be more durable than anticipated, which could result in interest rate increases and/or further tapering of quantitative easing policies enacted towards the outset of the COVID-19 pandemic sooner than previously expected.

***Cost of Solar Energy Systems and Energy Storage Systems.*** Upward pressure on prices of solar energy systems and energy storage systems may occur due to growth in the solar industry, regulatory policy changes, tariffs and duties, inflationary cost pressures and an increase in demand. As a result of these developments, we may pay higher prices on solar modules, which may make it less economical for us to serve certain markets. For much of 2022, attachment rates for energy storage systems have trended higher while the price to acquire has remained steady and increased slightly for some suppliers due to several market variables, including COVID-19, raw material shortages and freight prices, but this still remains a potential area of growth for us.

***Energy Storage Systems.*** Our energy storage systems increase our customers' independence from the centralized utility and provide on-site backup power when there is a grid outage due to storms, wildfires, other natural disasters and general power failures caused by supply or transmission issues. In addition, at times it can be more economic to consume less energy from the grid or, alternatively, to export solar energy back to the grid. Recent technological advancements for energy storage systems allow the energy storage system to adapt to pricing and utility rate shifts by controlling the inflows and outflows of power, allowing customers to increase the value of their solar energy system plus energy storage system. The energy storage system charges during the day, making the energy it stores available to the home or business when needed. It also features software that can customize power usage for the individual customer, providing backup power, optimizing solar energy consumption versus grid consumption or preventing export to the grid as appropriate. The software is tailored based on utility regulation, economic indicators and grid conditions. The combination of energy control, increased energy resilience and independence from the grid is strong incentive for customers to adopt solar and energy storage. As energy storage systems and their related software features become more advanced, we expect to see increased adoption of energy storage systems.

***Climate Change Action.*** As a result of increasing global awareness of and aversion to climate change impacts, we believe the renewable energy market in which we operate, and investment in climate solutions more broadly, will continue to grow as the impact of climate change increases. This trend, along with increasing commitments to reduce carbon emissions, is expected to result in increased demand for our products and services. Under the current presidential administration, the focus on cleaner energy sources and technology to decarbonize the U.S. economy continues to accelerate. The federal government's administration under President Joe Biden ("Biden administration") has taken immediate steps that we believe signify support for cleaner energy sources, including, but not limited to, rejoining the Paris Climate Accord, re-establishing a social price on carbon used in cost/benefit analysis for policy making and announcing a commitment to transition the U.S. economy to a net-zero carbon economy by 2050. We expect the Biden administration, combined with a closely divided Congress, to continue to take actions that are supportive of the renewable energy industry, such as incentivizing clean energy sources and supporting new investment in areas like renewables.

***Government Regulations, Policies and Incentives.*** Our growth strategy depends in significant part on government policies and incentives that promote and support solar energy and enhance the economic viability of distributed solar. These policies and incentives come in various forms, including net metering, eligibility for accelerated depreciation such as the modified accelerated cost recovery system, SRECs, tax abatements, rebates, renewable targets, incentive programs and tax credits, particularly the Section 48(a) ITC and the Section 25D Credit. The recently enacted IRA expanded and extended the tax credits available to solar energy projects in an effort to achieve the Biden administration's non-binding target of net-zero emissions by 2050, which we expect will increase demand for our services. The IRA allows qualifying homeowners to deduct up to 30% of the cost of installing residential solar energy systems from their U.S. federal income taxes, thereby returning a significant portion of the purchase price of the residential solar energy system to homeowners that may participate in our solar loan programs. Under the terms of the current extension, the residential tax credit will remain at 30% through the end of 2032, reduce to 26% for 2033, reduce to 22% for 2034, and further reduce to 0% after the end of 2034 for residential solar energy systems, unless it is extended before that time. The IRA also extended the investment tax credit for solar energy projects through at least 2033 and, depending on the location of a particular project, its size, its ability to satisfy certain labor and domestic content requirements and the category of consumers it serves, the investment tax credit percentage can range between 6% and 70%. Policies requiring solar on new roofs, such as those enacted in California and New York City, also support the growth of distributed solar. The sale of SRECs has constituted a significant portion of our revenue historically. A change in the

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

value of net metering credits or SRECs or changes in other policies or a loss or reduction in such incentives could decrease the attractiveness of distributed solar to us, our dealers and our customers in applicable markets, which could reduce our customer acquisition opportunities. Such a loss or reduction could also reduce our willingness to pursue certain customer acquisitions due to decreased revenue or income under our solar service agreements. Additionally, such a loss or reduction may also impact the terms of and availability of third-party financing. If any of these government regulations, policies or incentives are adversely amended, delayed, eliminated, reduced, retroactively changed or not extended beyond their current expiration dates or there is a negative impact from the recent federal law changes or proposals, our operating results and the demand for, and the economics of, distributed solar energy may decline, which could harm our business.

**Components of Results of Operations**

***Revenue.*** We recognize revenue from contracts with customers as we satisfy our performance obligations at a transaction price reflecting an amount of consideration based upon an estimated rate of return, net of cash incentives. We express this rate of return as the solar rate per kWh in the customer contract. The amount of revenue we recognize does not equal customer cash payments because we satisfy performance obligations ahead of cash receipt or evenly as we provide continuous access on a stand-ready basis to the solar energy system. We reflect the differences between revenue recognition and cash payments received in accounts receivable, other assets or deferred revenue, as appropriate.

*PPAs*. We have determined solar service agreements under which customers purchase electricity from us should be accounted for as revenue from contracts with customers. We recognize revenue based upon the amount of electricity delivered as determined by remote monitoring equipment at solar rates specified under the contracts. The PPAs generally have a term of 20 or 25 years with an opportunity for customers to renew for up to an additional 10 years, via two five-year or one 10-year renewal options.

*Lease Agreements*. We are the lessor under lease agreements for solar energy systems and energy storage systems, which we account for as revenue from contracts with customers. We recognize revenue on a straight-line basis over the contract term as we satisfy our obligation to provide continuous access to the solar energy system. The lease agreements generally have a term of 20 or 25 years with an opportunity for customers to renew for up to an additional 10 years, via two five-year or one 10-year renewal options.

We provide customers under our lease agreements a performance guarantee that each solar energy system will achieve a certain specified minimum solar energy production output. The specified minimum solar energy production output may not be achieved due to natural fluctuations in the weather or equipment failures from exposure and wear and tear outside of our control, among other factors. We determine the amount of guaranteed output based on a number of different factors, including (a) the specific site information related to the tilt of the panels, azimuth (a horizontal angle measured clockwise in degrees from a reference direction) of the panels, size of the solar energy system and shading on site; (b) the calculated amount of available irradiance (amount of energy for a given flat surface facing a specific direction) based on historical average weather data and (c) the calculated amount of energy output of the solar energy system.

If the solar energy system does not produce the guaranteed production amount, we are required to provide a bill credit or refund a portion of the previously remitted customer payments, where the bill credit or repayment is calculated as the product of (a) the shortfall production amount and (b) the dollar amount (guaranteed rate) per kWh that is fixed throughout the term of the contract. These bill credits or remittances of a customer's payments, if needed, are payable in January following the end of the first three years of the solar energy system's placed in service date and then every annual period thereafter. See Note 17, Commitments and Contingencies, to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.

*Inventory Sales*. Inventory sales revenue represents revenue from the direct sale of inventory to our dealers or other parties. We recognize the related revenue under ASC 606 upon shipment.

*SRECs*. Each SREC represents the environmental benefit of one megawatt hour (1,000 kWh) generated by a solar energy system. We sell SRECs to utilities and other third parties who use the SRECs to meet renewable portfolio standards and can do so separate from the actual electricity generated by the renewable-based generation source. We account for SRECs generated from solar energy systems owned by us, as opposed to those owned by our customers, as governmental incentives with no costs incurred to obtain them and do not consider those SRECs output of the underlying solar energy systems. We classify SRECs as inventory held until sold and delivered to third parties. We enter into economic hedges with major financial institutions related to expected production of SRECs through forward contracts to partially mitigate the risk of decreases in SREC market rates. While these fixed price forward contracts serve as an economic hedge against spot price fluctuations for the SRECs, the contracts do not qualify for hedge accounting and are not designated as cash flow hedges or fair value hedges. The contracts

require us to physically deliver the SRECs upon settlement. We recognize the related revenue upon the transfer of the SRECs to the counterparty. The costs related to the sales of SRECs are generally limited to fees for brokered transactions. Accordingly, the sale of SRECs in a period generally has a favorable impact on our operating results for that period. In certain circumstances we are required to purchase SRECs on the open market to fulfill minimum delivery requirements under our forward contracts.

*Cash Sales.* Cash sales revenue represents revenue from a customer's purchase of a solar energy system from us typically when purchasing a new home. We recognize the related revenue upon verification of the home closing.

*Loan Agreements*. We recognize payments received from customers under loan agreements (a) as interest income, to the extent attributable to earned interest on the contract that financed the customer's purchase of the solar energy system; (b) as a reduction of a note receivable on the balance sheet, to the extent attributable to a return of principal (whether scheduled or prepaid) on the contract that financed the customer's purchase of the solar energy system; and (c) as revenue, to the extent attributable to payments for operations and maintenance services provided by us. Similar to our lease agreements, we provide customers under our loan agreements a performance guarantee that each solar energy system will achieve a certain specified minimum solar energy production output, which is a significant proportion of its expected output.

*Other Revenue.* Other revenue includes certain state and utility incentives, revenue from the direct sale of solar energy systems and energy storage systems to customers with financing provided by us and sales of service plans and repair services. We recognize revenue from state and utility incentives in the periods in which they are earned. We recognize revenue from the direct sale of energy storage systems in the period in which the storage components are placed in service. Service plans are available to customers whose solar energy system was not originally sold by Sunnova. We recognize revenue from service plan contracts on a straight-line basis over the life of the contract, which is typically 10 years. We recognize revenue from repair services in the period in which the service was performed.

***Cost of Revenue—Depreciation.*** Cost of revenue—depreciation represents depreciation on solar energy systems under lease agreements and PPAs that have been placed in service.

***Cost of Revenue—Inventory Sales.*** Cost of revenue—inventory sales represents costs related to the procurement and direct sale of inventory to our dealers or other parties, including shipping and handling costs.

***Cost of Revenue—Other.*** Cost of revenue—other represents costs related to cash sales, costs to purchase SRECs on the open market, SREC broker fees and other items deemed to be a cost of providing the service of selling power to customers or potential customers, such as certain costs to service loan agreements, costs for filing under the Uniform Commercial Code to maintain title, title searches, credit checks on potential customers at the time of initial contract and other similar costs, typically directly related to the volume of customers and potential customers.

***Operations and Maintenance Expense.*** Operations and maintenance expense represents costs from third parties for maintaining and servicing the solar energy systems, property insurance, property taxes and warranties. When services for maintaining and servicing solar energy systems are provided by Sunnova personnel rather than third parties, those amounts are included in payroll costs classified within general and administrative expense. During the years ended December 31, 2022, 2021 and 2020, we incurred $21.2 million, $14.3 million and $7.4 million, respectively, of Sunnova personnel costs related to maintaining and servicing solar energy systems, which are classified in general and administrative expense. In addition, operations and maintenance expense includes write downs and write-offs related to inventory adjustments, gains and losses on disposals and other impairments and impairments and costs due to natural disaster losses net of insurance proceeds recovered under our business interruption and property damage insurance coverage for natural disasters.

***General and Administrative Expense.*** General and administrative expense represents costs for our employees, such as salaries, bonuses, benefits and all other employee-related costs, including stock-based compensation, professional fees related to legal, accounting, human resources, finance and training, information technology and software services, marketing and communications, IPO costs, acquisition costs, travel and rent and other office-related expenses. General and administrative expense also includes depreciation on assets not classified as solar energy systems, including information technology software and development projects, vehicles, furniture, fixtures, computer equipment and leasehold improvements and accretion expense on AROs. We capitalize a portion of general and administrative costs, such as payroll-related costs, that is related to employees who are directly involved in the design, construction, installation and testing of the solar energy systems but not directly associated with a particular asset. We also capitalize a portion of general and administrative costs, such as payroll-related costs, that is related to employees who are directly associated with and devote time to internal information technology software and development projects, to the extent of the time spent directly on the application and development stage of such software project.

***Other Operating Income.*** Other operating income primarily represents changes in the fair values of certain financial

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

instruments related to our investments in solar receivables and contingent consideration related to the installation and microgrid earnouts.

***Interest Expense, Net.*** Interest expense, net represents interest on our borrowings under our various debt facilities, amortization of debt discounts and deferred financing costs and realized and unrealized gains and losses on derivative instruments.

***Interest Income.*** Interest income represents interest income from the notes receivable under our loan program and income on short term investments with financial institutions.

***Loss on Extinguishment of Long-Term Debt, Net.*** Loss on extinguishment of long-term debt, net resulted from a make-whole payment related to the early repayment of one of our solar asset-backed notes.

***Other (Income) Expense.*** Other (income) expense primarily represents changes in the fair value of certain financial instruments related to non-operating assets.

***Income Tax Expense.*** We account for income taxes under Accounting Standards Codification 740, *Income Taxes*. As such, we determine deferred tax assets and liabilities based on temporary differences resulting from the different treatment of items for tax and financial reporting purposes. We measure deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to reverse. Additionally, we must assess the likelihood that deferred tax assets will be recovered as deductions from future taxable income. We have a full valuation allowance on our deferred tax assets because we believe it is more likely than not that our deferred tax assets will not be realized. We evaluate the recoverability of our deferred tax assets on a quarterly basis. The income tax expense includes the effects of taxes incurred in U.S. territories where the tax code for the respective territory may have separate tax reporting requirements, as applicable.

***Net Income (Loss) Attributable to Redeemable Noncontrolling Interests and Noncontrolling Interests.*** Net income (loss) attributable to redeemable noncontrolling interests and noncontrolling interests represents tax equity interests in the net income or loss of certain consolidated subsidiaries based on hypothetical liquidation at book value.

agreements and cash sales) increased from approximately 99,100 for the year ended December 31, 2021 to approximately 128,300 for the year ended December 31, 2022. Excluding SREC revenue, revenue under our loan agreements, inventory sales revenue, cash sales revenue and service revenue, on a weighted average number of systems basis, revenue remained relatively flat at $1,635 per system for the year ended December 31, 2021 compared to $1,632 per system for the same period in 2022. Inventory sales revenue increased by $196.0 million in the year ended December 31, 2022 compared to the year ended December 31, 2021 due to the sale of inventory to our dealers or other parties, which began in April 2022. SREC revenue increased by $7.2 million in the year ended December 31, 2022 compared to the year ended December 31, 2021 primarily as a result of an increase in SREC prices in New Jersey. The amount of SREC revenue recognized in each period is also affected by the total number of solar energy systems, weather seasonality and hedge and spot prices associated with the timing of the sale of SRECs. On a weighted average number of systems basis, revenues under our loan agreements increased from $286 per system for the year ended December 31, 2021 to $329 per system for the same period in 2022 (15% increase) primarily due to higher average system cost in 2022 than in 2021.

Interest income increased by $25.6 million in the year ended December 31, 2022 compared to the year ended December 31, 2021. This increase was primarily due to an increase in the weighted average number of systems with loan agreements from approximately 27,200 for the year ended December 31, 2021 to approximately 56,500 for the year ended December 31, 2022. On a weighted average number of systems basis, loan interest income decreased from $1,239 per system for the year ended December 31, 2021 to $999 per system for the year ended December 31, 2022 primarily due to a decrease in the average annual interest rate for customer loans due to market conditions.

***Loss on Extinguishment of Long-Term Debt, Net***

Loss on extinguishment of long-term debt, net decreased by $9.8 million in the year ended December 31, 2022 compared to the year ended December 31, 2021 primarily due to a make-whole payment related to the early repayment of one of our solar asset-backed notes in June 2021.

***Income Tax Expense***

Income tax expense increased by $3.6 million in the year ended December 31, 2022 compared to the year ended December 31, 2021 primarily due to an increase in taxes incurred in jurisdictions with separate tax-reporting requirements.

***Net Income (Loss) Attributable to Redeemable Noncontrolling Interests and Noncontrolling Interests***

Net income (loss) attributable to redeemable noncontrolling interests and noncontrolling interests changed by $40.7 million in the year ended December 31, 2022 compared to the year ended December 31, 2021 primarily due to an increase in income attributable to redeemable noncontrolling interests and noncontrolling interests from tax equity funds added in 2020 and 2021, partially offset by net loss attributable to redeemable noncontrolling interests and noncontrolling interests from tax equity funds added in 2022.

**Results of Operations—Year Ended December 31, 2021 Compared to Year Ended December 31, 2020**

See "*Management's Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations—Year Ended December 31, 2021 Compared to Year Ended December 31, 2020*" in our Annual Report on Form 10-K filed with the SEC on February 24, 2022.

**Liquidity and Capital Resources**

As of December 31, 2022, we had total cash of $545.6 million, of which $360.3 million was unrestricted, and $174.3 million of available borrowing capacity under our various financing arrangements. We seek to maintain diversified and cost-effective funding sources to finance and maintain our operations, fund capital expenditures, including customer acquisitions, and satisfy obligations arising from our indebtedness, which may include reducing debt prior to scheduled maturities through debt repurchases, either in the open market or in privately negotiated transactions, through debt redemptions or tender offers, or through repayments of bank borrowings. For a discussion of cash requirements from contractual and other obligations, see Note 17, Commitments and Contingencies, to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K. Historically, our primary sources of liquidity have included non-recourse and recourse debt, investor asset-backed and loan-backed securitizations and cash generated from operations. Our business model requires substantial outside financing arrangements to grow the business and facilitate the deployment of additional solar energy systems. We will seek to raise additional required capital, including from new and existing tax equity investors, additional borrowings, securitizations and other potential debt and equity financing sources. We believe our cash and financing arrangements, as further described below, will be sufficient to meet our anticipated cash needs for at least the next twelve months. As of December 31, 2022, we were in compliance with all debt covenants under our financing arrangements.

***Financing Arrangements***

The following is a description of our various financing arrangements. For a complete description of the facilities in place as of December 31, 2022 see Note 9, Long-Term Debt, to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.

*Tax Equity Fund Commitments*

As of December 31, 2022, we had undrawn committed capital of approximately $210.5 million under our tax equity funds, which may only be used to purchase and install solar energy systems. We intend to establish new tax equity funds in the future depending on their attractiveness, including the availability and size of Section 48(a) ITCs and Section 48E ITCs, and on investor demand for such funding. The terms of the tax equity funds' operating agreements contain allocations of taxable income (loss) and Section 48(a) ITCs that vary over time and adjust between the members after either the tax equity investor receives its contractual rate of return or after a specified date. The following table summarizes our tax equity commitments as of December 31, 2022:

*Warehouse and Other Debt Financings*

We from time to time enter into warehouse credit facilities as a source of funding. Under the warehouse credit facilities, revolving or term financing is provided to special purpose entities, which are typically our wholly-owned subsidiaries, and

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

secured, directly or indirectly, by qualifying solar energy systems (including, if applicable, energy storage systems) and related solar service agreements and/or qualifying solar loans and related solar assets used to finance the purchase and/or installation of qualifying solar energy systems. The cash flows generated by these solar service agreements and/or solar loans, as applicable, are used to cover required debt service payments under the related credit facility and satisfy the expenses and reserve requirements of the special purpose entities. The warehouse credit facilities allow for the pooling and transfer of eligible solar energy systems and related solar service agreements and/or solar loans and related solar assets, as applicable, on a non-recourse basis to the subsidiary or us, subject to certain limited exceptions. In connection with these warehouse credit facilities, certain of our affiliates receive a fee for managing and servicing the solar loans, solar energy systems and/or energy storage systems, as applicable, pursuant to management and servicing agreements. The special purpose entities are also typically required to maintain reserve accounts, including, among other reserve accounts that may be required, a liquidity reserve account and a reserve account for equipment replacements, each of which are funded from initial deposits or cash flows to the levels specified therein.

The warehouse credit facility structures include certain features designed to protect lenders. One of the common primary features relates to certain events, such as the insufficiency of cash flows in the collateral pool of assets to meet contractual requirements, the occurrence of which triggers an early repayment of the loans and limits the relevant borrower's ability to obtain additional advances or distribute funds to us. We refer to this as an "amortization event", which may be based on, among other things, a debt service coverage ratio falling or remaining below certain levels, default levels of solar loans, solar energy systems and/or energy storage systems, as applicable, exceeding certain thresholds or excess spread falling below certain levels over a multiple month period. In the event of an amortization event, the availability period under a revolving warehouse credit facility may terminate and the borrower may be required to repay the affected outstanding borrowings using available collections received from the asset pool. However, the period of ultimate repayment would be determined by the amount and timing of collections received. An amortization event would impair our liquidity and may require us to utilize our other available contingent liquidity or rely on alternative funding sources, which may or may not be available at the time. The debt agreements of our warehouse credit facilities also typically contain customary events of default for solar warehouse financings that entitle the lenders to take various actions, including the acceleration of amounts due under the related debt agreement and foreclosure on the borrower's assets.

In April 2017, one of our subsidiaries, EZOP, entered into a secured revolving credit facility with Credit Suisse AG, New York Branch, as agent, and the lenders party thereto. The EZOP revolving credit facility was amended and restated in March 2019 and further amended in September 2019, December 2019, January 2020, March 2020, September 2020, March 2021, June 2022, July 2022, August 2022 and September 2022. Under the amended EZOP revolving credit facility, EZOP may borrow up to an initial aggregate committed amount of $450.0 million, with an uncommitted maximum facility amount of $575.0 million, subject to a borrowing base calculated based on a specified advance rate applied to the net outstanding principal balance of the solar loans securing the EZOP revolving credit facility. The proceeds of the loans under the EZOP revolving credit facility are available for funding the purchase of solar loans, making deposits in EZOP's reserve accounts and paying fees in connection with the EZOP revolving credit facility. The EZOP revolving credit facility bears interest at an annual rate based on Term SOFR (as defined by such revolving credit facility). The EZOP revolving credit facility has a maturity date occurring in November 2024.

The securitization structures include certain features designed to protect investors. The primary feature relates to the availability and adequacy of cash flows in the securitized pool of assets to meet contractual requirements, the insufficiency of which triggers an early repayment of the notes. We refer to this as "early amortization", which may be based on, among other things, a debt service coverage ratio falling or remaining below certain levels. As of December 31, 2022, we have not had any early amortizations under any of our securitizations. In the event of an early amortization, the notes issuer would be required to repay the affected outstanding securitized borrowings using available collections received from the asset pool. However, the period of ultimate repayment would be determined based on the amount and timing of collections received and, in limited circumstances, early amortization may be cured prior to full repayment. An early amortization event would impair our liquidity and may require us to utilize our available non-securitization related contingent liquidity or rely on alternative funding sources, which may or may not be available at the time. The indentures of our securitizations also typically contain customary events of default for solar securitizations that may entitle the noteholders to take various actions, including the acceleration of amounts due under the related indenture and foreclosure on the issuer's assets.

*Senior Notes*

In May 2021, we issued and sold an aggregate principal amount of $575.0 million of our 0.25% convertible senior notes ("0.25% convertible senior notes") in a private placement at a discount to the initial purchasers of 2.5%, for an aggregate purchase price of $560.6 million. The 0.25% convertible senior notes mature in December 2026 unless earlier redeemed, repurchased or converted. In connection with the pricing of the 0.25% convertible senior notes, we used proceeds of $91.7 million to enter into privately negotiated capped call transactions, which are expected to reduce the potential dilution to common shares and/or offset potential cash payments that could be required to be made in excess of the principal amount upon any exchange of notes. Such reduction and/or offset is subject to a cap initially equal to $60.00 per share, subject to adjustments.

In August 2021, we issued and sold an aggregate principal amount of $400.0 million of our 5.875% senior notes ("5.875% senior notes") in a private placement at a discount to the initial purchasers of 1.24%, for an aggregate purchase price of $395.0 million. The 5.875% senior notes mature in September 2026.

In August 2022, we issued and sold an aggregate principal amount of $600.0 million of our 2.625% convertible senior notes ("2.625% convertible senior notes") in a private placement at a discount to the initial purchasers of 2.5%, for an aggregate purchase price of $585.0 million. The 2.625% convertible senior notes mature in February 2028 unless earlier redeemed, repurchased or converted. In connection with the pricing of the 2.625% convertible senior notes, we used proceeds of $48.4 million to enter into privately negotiated capped call transactions, which are expected to reduce the potential dilution to

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)Does not include amounts related to the contingent obligation to purchase all of a tax equity investor's units upon exercise of their withdrawal rights. The withdrawal price for the tax equity investors' interest in the respective fund is equal to the lesser of: (a) a fixed price and (b) the fair market value of such interest. Due to uncertainties associated with estimating the timing and amount of the withdrawal price, we cannot determine the potential future payments that we could have to make under these withdrawal rights. For additional information regarding the withdrawal rights see Note 13, Redeemable Noncontrolling Interests and Noncontrolling Interests, to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)Interest payments related to long-term debt and interest rate swaps and caps are calculated and estimated for the periods presented based on the amount of debt outstanding and the interest rates as of December 31, 2022.

| &nbsp;&nbsp;&nbsp;&nbsp;Net increase in cash, cash equivalents and restricted cash | $153677 | $14004 | $139673 |

---

***Operating Activities***

Net cash used in operating activities increased by $124.2 million in the year ended December 31, 2022 compared to the year ended December 31, 2021. This increase is primarily a result of increases in purchases of inventory and prepaid inventory of $45.4 million and payments to dealers for exclusivity and other bonus arrangements of $21.2 million. This increase is also due to a decrease in net inflows of $12.8 million in 2022 compared to net inflows of $17.4 million in 2021 based on: (a) our net loss of $130.3 million in 2022 excluding non-cash operating items of $143.1 million, primarily from depreciation, impairments and losses on disposals, amortization of intangible assets, amortization of deferred financing costs and debt discounts,

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

unrealized net gains on derivatives, unrealized net gains on fair value instruments and equity securities and equity-based compensation charges, which results in net inflows of $12.8 million and (b) our net loss of $147.5 million in 2021 excluding non-cash operating items of $164.9 million, primarily from depreciation, impairments and losses on disposals, amortization of intangible assets, amortization of deferred financing costs and debt discounts, unrealized net gains on derivatives, unrealized net gains on fair value instruments, losses on extinguishment of long-term debt and equity-based compensation charges, which results in net inflows of $17.4 million. These net differences between the two periods resulted in a net change in operating cash flows of $4.6 million in 2022 compared to 2021.

***Investing Activities***

Net cash used in investing activities increased by $740.4 million in the year ended December 31, 2022 compared to the year ended December 31, 2021. This increase is primarily a result of increases in payments for investments and customer notes receivable of $507.3 million and purchases of property and equipment, primarily solar energy systems, of $313.7 million. This increase is partially offset by increases in proceeds from customer notes receivable of $42.9 million and proceeds from investments in solar receivables of $9.2 million.

***Financing Activities***

Net cash provided by financing activities increased by $1.0 billion in the year ended December 31, 2022 compared to the year ended December 31, 2021. This increase is primarily a result of an increase in net borrowings under our debt facilities of $891.1 million, net contributions from our redeemable noncontrolling interests and noncontrolling interests of $85.4 million and a decrease in the purchase of capped call transactions of $43.2 million. This increase is partially offset by a decrease in net proceeds from the issuance of common stock of $13.7 million.

**Historical Cash Flows—Year Ended December 31, 2021 Compared to Year Ended December 31, 2020**

See "*Management's Discussion and Analysis of Financial Condition and Results of Operations—Historical Cash Flows—Year Ended December 31, 2021 Compared to Year Ended December 31, 2020*" in our Annual Report on Form 10-K filed with the SEC on February 24, 2022 pursuant to the Securities Exchange Act of 1934, as amended.

**Seasonality**

See "*Business—Seasonality"*.

**Critical Accounting Policies and Estimates**

Our discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with GAAP which requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, expenses, cash flows and related disclosures. We base our estimates on historical experience and on various other assumptions we believe to be reasonable under the circumstances. In many instances, we could have reasonably used different accounting estimates, and in other instances, changes in the accounting estimates are reasonably likely to occur from period-to-period. Actual results may differ from these estimates. Our future consolidated financial statements will be affected to the extent our actual results materially differ from these estimates.

We identify our most critical accounting policies as those that are the most pervasive and important to the portrayal of our financial position and results of operations, and that require the most difficult, subjective, and/or complex judgments by management regarding estimates about matters that are inherently uncertain. We believe the assumptions and estimates associated with our principles of consolidation, the valuation of assets acquired and liabilities assumed in acquisitions, the estimated useful life of our solar energy systems, the valuation of the removal assumptions, including costs, associated with AROs, the valuation of redeemable noncontrolling interests and noncontrolling interests and our allowance for current expected credit losses have the greatest subjectivity and impact on our consolidated financial statements. Therefore, we consider these to be our critical accounting policies and estimates and discuss these items in detail below. See Note 2, Significant Accounting Policies, to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for further discussion of our accounting policies.

***Principles of Consolidation***

Our consolidated financial statements reflect our accounts and those of our subsidiaries in which we have a controlling financial interest. The typical condition for a controlling financial interest is holding a majority of the voting interests of an

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

entity. However, a controlling financial interest may also exist in entities, such as variable interest entities ("VIEs"), through arrangements that do not involve holding a majority of the voting interests. We consolidate any VIE of which we are the primary beneficiary, which is defined as the party that has (a) the power to direct the activities of a VIE that most significantly impact the VIE's economic performance and (b) the obligation to absorb losses or receive benefits from the VIE that could potentially be significant to the VIE. We evaluate our relationships with our VIEs on an ongoing basis to determine whether we continue to be the primary beneficiary. We have eliminated all intercompany transactions in consolidation.

***Acquisitions***

Business combinations are accounted for using the acquisition method of accounting. The purchase price of an acquisition is measured at the estimated fair value of the assets acquired, equity instruments issued and liabilities assumed at the acquisition date. Any noncontrolling interests acquired are also initially measured at fair value. Costs that are directly attributable to the acquisition are expensed as incurred to general and administrative expense. We recognize goodwill if the aggregate fair value of the total purchase consideration and the noncontrolling interests is in excess of the aggregate fair value of the assets acquired and liabilities assumed.

Asset acquisitions are measured based on the cost to us, including transaction costs. Asset acquisition costs, or the consideration transferred by us, are assumed to be equal to the fair value of the net assets acquired. If the consideration transferred is cash, measurement is based on the amount of cash we paid to the seller, as well as transaction costs incurred. Consideration given in the form of non-monetary assets, liabilities incurred or equity instruments issued is measured based on either the cost to us or the fair value of the assets or net assets acquired, whichever is more clearly evident. The cost of an asset acquisition is allocated to the assets acquired based on their estimated fair values. Goodwill is not recognized in an asset acquisition.

The fair values of the assets acquired and liabilities assumed are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. Significant estimates include, but are not limited to, discount rates, forecasted cash flows, forecasted customer growth and earnout consideration. These estimates are inherently uncertain and unpredictable.

***Useful Life of Solar Energy Systems***

Our solar energy systems have an estimated useful life of 35 years. We considered both (a) available information related to the technology currently being employed in the solar energy systems and (b) the terms of the solar leases that have a 25 year term with two five-year renewal options to conclude a 35 year useful life is appropriate. In addition, we reviewed numerous published and online sources from academia, government institutions and private industry and held discussions with certain manufacturers of our solar energy systems to support our estimated useful life of 35 years for the crystalline silicone solar modules we use. We define the useful life of a solar module as the duration for which a solar module operates at or above 80% of its initial power output, which we understand to be the generally accepted standard used by government, academia and the solar industry.

Depreciation and amortization of solar energy systems are calculated using the straight-line method over the estimated useful lives of the solar energy systems and are recorded in cost of revenue—depreciation. Depreciation begins when a solar energy system is placed in service. Costs associated with improvements to a solar energy system, which extend the life, increase the capacity or improve the efficiency of the solar energy systems, are capitalized and depreciated over the remaining life of the asset.

***ARO***

We have AROs arising from contractual or regulatory requirements to perform certain asset retirement activities at the time the solar energy systems are disposed. We recognize an ARO at the point an obligating event takes place, typically when the solar energy system is placed in service. An asset is considered retired when it is permanently taken out of service, such as through a sale or disposal.

The liability is initially measured at fair value based on the present value of estimated removal costs and subsequently adjusted for changes in the underlying assumptions and for accretion expense. We estimate approximately half of our solar energy systems will require removal at our expense in the future. The corresponding asset retirement costs are capitalized as part of the carrying amount of the solar energy system and depreciated over the solar energy system's remaining useful life. We may revise our estimated future liabilities based on recent actual experiences, changes in certain customer-specific estimates and other cost estimate changes. If there are changes in estimated future costs, those changes will be recorded as either a

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

reduction or addition in the carrying amount of the remaining unamortized asset and the ARO and either decrease or increase depreciation and accretion expense amounts prospectively. Inherent in the calculation of the fair value of our AROs are numerous assumptions and judgments, including the ultimate settlement amounts, inflation factors, credit adjusted discount rates, timing of settlement and changes in the legal, regulatory, environmental and political environments. Due to the intrinsic uncertainties present when estimating asset retirement costs, as well as asset retirement dates, our ARO estimates are subject to ongoing volatility.

***Redeemable Noncontrolling Interests and Noncontrolling Interests***

Noncontrolling interests represent third-party interests in the net assets of certain consolidated subsidiaries (the "tax equity entities"). For these tax equity entities, we have determined the appropriate methodology for calculating the noncontrolling interest balances that reflects the substantive economic arrangements in the operating agreements is a balance sheet approach using the hypothetical liquidation at book value ("HLBV") method. Under the HLBV method, the amounts reported as noncontrolling interests in the consolidated balance sheets represent the amounts third-party investors would hypothetically receive at each balance sheet date under the liquidation provisions of the operating agreements, assuming the net assets of the subsidiaries were liquidated at amounts determined in accordance with GAAP and distributed to the investors. The noncontrolling interest balances in these subsidiaries are reported as a component of equity in the consolidated balance sheets. The amount of income or loss allocated to noncontrolling interests in the results of operations for the subsidiaries using HLBV are determined as the difference in the noncontrolling interest balances in the consolidated balance sheets at the start and end of each reporting period, after taking into account any capital transactions between the subsidiaries and the third-party investors. Factors used in the HLBV calculation include GAAP income (loss), taxable income (loss), capital contributions, investment tax credits, distributions and the stipulated targeted investor return specified in the subsidiaries' operating agreements. Changes in these factors could have a significant impact on the amounts that investors would receive upon a hypothetical liquidation. The use of the HLBV method to allocate income (loss) to the noncontrolling interest holders may create volatility in the consolidated statements of operations as the application of HLBV can drive changes in net income or loss attributable to noncontrolling interests from period to period. We classify certain noncontrolling interests with redemption features that are not solely within our control outside of permanent equity in the consolidated balance sheets. Redeemable noncontrolling interests are reported using the greater of the carrying value at each reporting date as determined by the HLBV method or the estimated redemption value at the end of each reporting period. Estimating the redemption value of the redeemable noncontrolling interests requires the use of significant assumptions and estimates, such as projected future cash flows.

***Current Expected Credit Losses***

Our allowance for current expected credit losses is deducted from the customer notes receivable amortized cost to present the net amount expected to be collected. It is measured on a collective (pool) basis when similar risk characteristics (such as financial asset type, customer credit rating, contractual term and vintage) exist. In determining the allowance for credit losses, we identify customers with potential disputes or collection issues and consider our historical level of credit losses and current economic trends that might impact the level of future credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics, such as differences in underwriting standards. Expected credit losses are estimated over the contractual term of the loan agreements based on the best available data at the time, and are adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals and modifications unless either of the following applies: (a) we have a reasonable expectation at the reporting date that a troubled debt restructuring will be executed with an individual customer or (b) the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancelable by us. We review the allowance quarterly for any significant macroeconomic trends affecting the market but not yet impacting us. Assessments performed throughout the year include normal macroeconomic trends (e.g. delinquency and default and loss rates from leading credit bureaus by industry) as well as trends specifically related to the COVID-19 pandemic (e.g. forbearance and credit quality). While making adjustments to loss rates is ultimately a subjective determination, we have created an internal and external data-driven evaluation process to ensure any adjustments or updates to the model are informed and fact-based prior to executing such a change.

**Item 7A. Quantitative and Qualitative Disclosures About Market Risk.**

We are exposed to various market risks in the ordinary course of our business. Market risk is the potential loss that may result from market changes associated with our business or with an existing or forecasted financial or commodity transaction.

Our primary exposure includes changes in interest rates because certain borrowings bear interest at floating rates based on SOFR or a similar index plus a specified margin. We sometimes manage our interest rate exposure on floating-rate debt by entering into derivative instruments to hedge all or a portion of our interest rate exposure on certain debt facilities. We do not enter into any derivative instruments for trading or speculative purposes. Changes in economic conditions could result in higher interest rates, thereby increasing our interest expense and operating expenses and reducing funds available to capital investments, operations and other purposes. A hypothetical 10% increase in our interest rates on our variable-rate debt facilities would have increased our interest expense by $3.7 million and $1.7 million for the years ended December 31, 2022 and 2021, respectively.

**Report of Independent Registered Public Accounting Firm**

To the Board of Directors and Stockholders of Sunnova Energy International Inc.

***Opinions on the Financial Statements and Internal Control over Financial Reporting***

We have audited the accompanying consolidated balance sheets of Sunnova Energy International Inc. and its subsidiaries (the "Company") as of December 31, 2022 and 2021, and the related consolidated statements of operations, of redeemable noncontrolling interests and equity and of cash flows for each of the three years in the period ended December 31, 2022, including the related notes and financial statement schedule listed in the accompanying index (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2022, based on criteria established in *Internal Control - Integrated Framework* (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO").

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on criteria established in *Internal Control - Integrated Framework* (2013) issued by the COSO.

***Basis for Opinions***

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company's consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

***Definition and Limitations of Internal Control over Financial Reporting***

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

***Critical Audit Matters***

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

*Initial Accounting Assessment of New Tax Equity Partnerships ("TEPs")*

As described in Notes 1, 2, and 13 to the consolidated financial statements, the Company admitted tax equity investors of TEP6B, TEP6C, TEP6D, TEP6E, TEP7A, TEP7B, TEP7C and TEP7D through a TEP structure in 2022. As of December 31, 2022, the Company had approximately $165.7 million of redeemable noncontrolling interest and $448.6 million of noncontrolling interest, a portion of which relates to these TEPs. The Company forms TEPs with its investors in the ordinary course of business to facilitate the funding and monetization of certain attributes associated with the Company's solar energy systems. The typical condition for a controlling financial interest is holding a majority of the voting interests of an entity. However, a controlling financial interest may also exist in entities, such as variable interest entities ("VIEs"), through arrangements that do not involve holding a majority of the voting interests. The Company consolidates a VIE when it is the primary beneficiary, which is defined as the party that has (a) the power to direct the activities of the VIE that most significantly impact the VIE's economic performance and (b) the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. As disclosed by management, assets, liabilities and operating results of these partnerships are consolidated in the financial statements. The tax equity investors' share of the net assets of these tax equity funds are recognized as redeemable noncontrolling interests and noncontrolling interests in the consolidated balance sheet. Additionally, management has determined that the appropriate methodology for calculating the noncontrolling interest balances that reflects the substantive economic arrangements in the operating agreements is a balance sheet approach using the hypothetical liquidation at book value ("HLBV") method.

The principal considerations for our determination that performing procedures relating to the initial accounting assessment of new TEP arrangements is a critical audit matter are the significant judgment by management in the assessment of whether the Company is the primary beneficiary of the TEP, thus requiring consolidation of the entity, as well as the application of the HLBV methodology based on the terms of the operating agreements in the initial year, which in turn led to a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating the initial accounting assessment of whether the Company is the primary beneficiary of the new TEP and the application of the HLBV methodology based on the substantive economic arrangements of the TEP operating agreements. In addition, the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management's assessment of the initial accounting for the new TEPs. These procedures also included, among others, using professionals with specialized skill and knowledge to (i) evaluate the appropriateness of management's application of the HLBV methodology based on the substantive economic arrangements of the TEP operating agreements and (ii) evaluate management's assessment of whether the Company qualifies as the primary beneficiary of the TEP, and therefore consolidates the TEP.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**(1) Description of Business and Basis of Presentation**

We are a leading Energy as a Service ("EaaS") provider, serving over 279,000 customers in more than 45 United States ("U.S.") states and territories. Sunnova Energy Corporation was incorporated in Delaware on October 22, 2012 and formed Sunnova Energy International Inc. ("SEI") as a Delaware corporation on April 1, 2019. We completed our initial public offering on July 29, 2019 (our "IPO"); and in connection with our IPO, all of Sunnova Energy Corporation's ownership interests were contributed to SEI. Unless the context otherwise requires, references in this report to "Sunnova," the "Company," "we," "our," "us," or like terms, refer to SEI and its consolidated subsidiaries.

We have a differentiated dealer model in which we partner with local dealers who originate, design and install our customers' solar energy systems, energy storage systems and related products and services on our behalf. Our focus on our dealer model enables us to leverage our dealers' specialized knowledge, connections and experience in local markets to drive customer origination while providing our dealers with access to high quality products at competitive prices, as well as technical oversight and expertise. We believe this structure provides operational flexibility, reduces exposure to labor shortages and lowers fixed costs relative to our peers, furthering our competitive advantage.

We provide our services through long-term agreements with a diversified pool of credit quality customers. Our solar service agreements typically are structured as either a legal-form lease (a "lease") of a solar energy system and/or energy storage system to the customer, the sale of the solar energy system's output to the customer under a power purchase agreement ("PPA") or the purchase of a solar energy system and/or energy storage system either with financing provided by us (a "loan") or paid in full by the customer (a "sale"); however, we also offer service plans and repair services for systems we did not originate. We make it possible in some states for a customer to obtain a new roof and other ancillary products as part of their solar loan. We also allow customers originated through our homebuilder channel the option of purchasing the system when the customer closes on the purchase of a new home. The initial term of our solar service agreements is typically between 10 and 25 years, during which time we provide or arrange for ongoing services to customers, including monitoring, maintenance and warranty services. Our lease and PPA agreements typically include an opportunity for customers to renew for up to an additional 10 years, via two five-year or one 10-year renewal options. Customer payments and rates can be fixed for the duration of the solar service agreement or escalated at a pre-determined percentage annually. We also receive tax benefits and other incentives from leases and PPAs, a portion of which we finance through tax equity, non-recourse debt structures and hedging arrangements in order to fund our upfront costs, overhead and growth investments. Our future success depends in part on our ability to raise capital from third-party investors and commercial sources. We have an established track record of attracting capital from diverse sources. From our inception through December 31, 2022, we have raised more than $11.8 billion in total capital commitments from equity, debt and tax equity investors.

***Basis of Presentation***

The accompanying annual audited consolidated financial statements ("consolidated financial statements") include our consolidated balance sheets, statements of operations, statements of redeemable noncontrolling interests and equity and statements of cash flows and have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") from records maintained by us. Our consolidated financial statements include our accounts and those of our subsidiaries in which we have a controlling financial interest. In accordance with the provisions of the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 810, *Consolidation*, we consolidate any VIE of which we are the primary beneficiary. We form VIEs with our investors in the ordinary course of business to facilitate the funding and monetization of certain attributes associated with our solar energy systems. The typical condition for a controlling financial interest is holding a majority of the voting interests of an entity. However, a controlling financial interest may also exist in entities, such as VIEs, through arrangements that do not involve holding a majority of the voting interests. A primary beneficiary is defined as the party that has (a) the power to direct the activities of a VIE that most significantly impact the VIE's economic performance and (b) the obligation to absorb losses or receive benefits from the VIE that could potentially be significant to the VIE. We do not consolidate a VIE in which we have a majority ownership interest when we are not considered the primary beneficiary. We have considered the provisions within the contractual arrangements that grant us power to manage and make decisions that affect the operation of our VIEs, including determining the solar energy systems contributed to the VIEs, and the installation, operation and maintenance of the solar energy systems. We consider the rights granted to the other investors under the contractual arrangements to be more protective in nature rather than substantive participating rights. As such, we have determined we are the primary beneficiary of our VIEs and evaluate our relationships with our VIEs on an ongoing basis to determine whether we continue to be the primary beneficiary. We have eliminated all intercompany transactions in consolidation.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

***Reclassifications***

Certain prior period amounts have been reclassified to conform to the current period presentation. These reclassifications did not have a significant impact on our consolidated financial statements.

**(2) Significant Accounting Policies**

***Use of Estimates***

The application of GAAP in the preparation of the consolidated financial statements requires us to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ materially from those estimates.

***Cash and Cash Equivalents***

We maintain cash and cash equivalents, which consists principally of demand deposits, with investment-grade financial institutions. We are exposed to credit risk to the extent cash and cash equivalents balances exceed amounts covered by the Federal Deposit Insurance Corporation ("FDIC"). As of December 31, 2022 and 2021, we had cash and cash equivalents deposits of $337.5 million and $225.7 million, respectively, in excess of the FDIC's current insured limit of $250,000. We have not experienced any losses on our deposits of cash and cash equivalents.

***Restricted Cash***

We record cash that is restricted as to withdrawal or use under the terms of certain contractual agreements as restricted cash. Our restricted cash primarily represents cash held to service certain payments under the Sunnova EZ-Own Portfolio, LLC ("EZOP"), Sunnova TEP Holdings, LLC ("TEPH"), Helios II Issuer, LLC ("HELII"), Helios III Issuer, LLC ("HELIII"), Sunnova RAYS I Issuer, LLC ("RAYSI"), Sunnova Sol Issuer, LLC ("SOLI"), Sunnova Helios IV Issuer, LLC ("HELIV"), Sunnova TEP IV-G, LLC ("TEPIVG"), Sunnova Asset Portfolio 8, LLC ("AP8"), Sunnova Sol II Issuer, LLC ("SOLII"), Sunnova Helios V Issuer, LLC ("HELV"), Sunnova Helios VI Issuer, LLC ("HELVI"), Sunnova Helios VII Issuer, LLC ("HELVII"), Sunnova TEP V-A, LLC ("TEPVA"), Sunnova TEP V-B, LLC ("TEPVB"), Sunnova TEP V-C, LLC ("TEPVC"), Sunnova TEP 6-B, LLC ("TEP6B"), Sunnova Sol III Issuer, LLC ("SOLIII"), Sunnova Helios VIII Issuer, LLC ("HELVIII"), Sunnova Helios IX Issuer, LLC ("HELIX"), Sunnova Sol IV Issuer, LLC ("SOLIV"), Sunnova Helios X Issuer, LLC ("HELX"), Sunnova TEP 7-A, LLC ("TEP7A"), Sunnova TEP 7-B, LLC ("TEP7B"), Sunnova TEP 7-C, LLC ("TEP7C") and Sunnova TEP 7-D, LLC ("TEP7D") financing arrangements (see Note 9, Long-Term Debt and Note 13, Redeemable Noncontrolling Interests and Noncontrolling Interests) and balances collateralizing outstanding letters of credit related to a reinsurance agreement and one of our operating leases for office space (see Note 17, Commitments and Contingencies). The following table presents the detail of restricted cash as recorded in other current assets and other assets in the consolidated balance sheets:

&nbsp;&nbsp;&nbsp;&nbsp;(1) Of this amount, $51.7 million and $80.2 million is recorded in other current assets as of December 31, 2022 and 2021, respectively.

We are exposed to credit risk to the extent restricted cash balances exceed amounts covered by the FDIC. As of December 31, 2022 and 2021, we had restricted cash deposits of $179.8 million and $144.3 million, respectively, in excess of the FDIC's current insured limit of $250,000. We have not experienced any losses on our deposits of restricted cash.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

***Accounts Receivable***

*Accounts Receivable—Trade.*&nbsp;&nbsp;&nbsp;&nbsp;Accounts receivable—trade primarily represents trade receivables from customers that are generally collected in the subsequent month. Accounts receivable—trade is recorded net of an allowance for credit losses, which is based on our assessment of the collectability of customer accounts based on the best available data at the time. We review the allowance by considering factors such as historical experience, customer credit rating, contractual term, aging category and current economic conditions that may affect a customer's ability to pay to identify customers with potential disputes or collection issues. We write off accounts receivable when we deem them uncollectible. The following table presents the changes in the allowance for credit losses recorded against accounts receivable*—*trade, net in the consolidated balance sheets:

| &nbsp;&nbsp;&nbsp;&nbsp;Recoveries | 264 | 173 |
| Balance at end of period | $1676 | $1044 |

---

*Accounts Receivable—Other.*&nbsp;&nbsp;&nbsp;&nbsp;Accounts receivable—other primarily represents receivables from our dealers or other parties related to the sale of inventory and the use of inventory procured by us.

***Inventory***

Inventory is stated at the lower of cost and net realizable value using the first-in, first-out method. Inventory primarily represents (a) raw materials, such as energy storage systems, photovoltaic modules, inverters, meters and modems, (b) homebuilder construction in progress and (c) other associated equipment purchased. These materials are typically procured by us and used by our dealers, sold to our dealers or held for use as original parts on new solar energy systems or replacement parts on existing solar energy systems. We remove these items from inventory and record the transaction in typically one of these manners: (a) expense to operations and maintenance expense when installed as a replacement part for a solar energy system, (b) recognize in accounts receivable—other when procured by us and used by our dealers, (c) expense to cost of revenue—inventory sales if sold directly to a dealer or other party, (d) capitalize to property and equipment when installed on an existing home or business or (e) capitalize to property and equipment when placed in service under the homebuilder program. We periodically evaluate our inventory for unusable and obsolete items based on assumptions about future demand and market conditions. Based on this evaluation, provisions are made to write inventory down to net realizable value. The following table presents the detail of inventory as recorded in other current assets in the consolidated balance sheets:

---

***Concentrations of Risk***

Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash, cash equivalents, restricted cash, accounts receivable and notes receivable. The concentrated risk associated with cash, cash equivalents and restricted cash is mitigated by our policy of banking with creditworthy institutions. Typically, amounts on deposit with certain banking institutions exceed FDIC insurance limits. We do not generally require collateral or other security

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

to support accounts receivable. To reduce credit risk related to our relationship with our dealers, management performs periodic credit evaluations and ongoing assessments of our dealers' financial condition.

***Concentration of Services and Equipment from Dealers***

We utilize a network of approximately 300 dealers as of December 31, 2022. During the year ended December 31, 2022, three dealers accounted for approximately 26%, 16% and 11%, respectively, of our total expenditures to dealers. During the year ended December 31, 2021, two dealers accounted for approximately 28% and 13%, respectively, of our total expenditures to dealers. During the year ended December 31, 2020, two dealers accounted for approximately 34% and 13%, respectively, of our total expenditures to dealers. No other dealer accounted for more than 10% of our expenditures to dealers during the years ended December 31, 2022, 2021 and 2020.

***Concentration of Revenue from Dealers***

During the year ended December 31, 2022, one dealer accounted for approximately 16% of our total revenue. No other dealer accounted for more than 10% of our revenue during the years ended December 31, 2022, 2021 and 2020.

***Dealer Commitments***

We enter into exclusivity and other similar agreements with certain key dealers pursuant to which we agree to pay an incentive if such dealers install a certain minimum number of solar energy systems within specified periods. These incentives are recorded in other assets in the consolidated balance sheets and are amortized to general and administrative expense in the consolidated statements of operations generally over the term of the customer agreements, which is estimated at an average of 23 years. See Note 17, Commitments and Contingencies.

***Fair Value of Financial Instruments***

Fair value is an exit price representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions market participants would use in pricing an asset or a liability. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. ASC 820 establishes a three-tier fair value hierarchy, which prioritizes inputs that may be used to measure fair value as follows:

&nbsp;&nbsp;&nbsp;&nbsp;• Level 1—Observable inputs that reflect unadjusted quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date.

&nbsp;&nbsp;&nbsp;&nbsp;• Level 2—Observable inputs other than Level 1 prices, such as quoted market prices for similar assets or liabilities in active markets, quoted market prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

&nbsp;&nbsp;&nbsp;&nbsp;• Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy must be determined based on the lowest level input that is significant to the fair value measurement. An assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and consideration of factors specific to the asset or liability. Our financial instruments include cash, cash equivalents, accounts receivable, customer notes receivable, investments in solar receivables, accounts payable, accrued expenses, long-term debt, interest rate swaps and caps and contingent consideration. The carrying values of accounts receivable, accounts payable and accrued expenses approximate the fair values due to the fact that they are short-term in nature and based on quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date (Level 1). We estimate the fair value of our customer notes receivable based on interest rates currently offered under the loan program with similar maturities and terms (Level 3). We estimate the fair value of our investments in solar receivables based on a discounted cash flows model that utilizes market data related to solar irradiance, production factors by region and projected electric utility rates in order to build up revenue projections (Level 3). In addition, lease-related revenue and maintenance and service costs were supported through the use of available market studies and data. We estimate the fair value of our fixed-rate long-term debt based on an analysis of debt with similar book values, maturities and required market yields based on current interest rates (Level 3). We determine the fair values of the interest rate derivative transactions based on a discounted cash flow method using contractual terms of the transactions and counterparty credit risk as key inputs. The floating interest rate is based on observable rates consistent with the frequency of the interest cash flows (Level 2). For contingent consideration, we estimate the fair value of the installation earnout using the Monte Carlo model based on the forecasted placements for the installations and the

Significant increases or decreases in the volatility, revenue risk premium, probability of success or risk-free discount rate in isolation could result in a significantly higher or lower fair value measurement.

***Derivative Instruments***

Our derivative instruments consist of interest rate swaps and caps that are not designated as cash flow hedges or fair value hedges. We use interest rate swaps and caps to manage our net exposure to interest rate changes. We record the derivatives in other assets, other current liabilities and other long-term liabilities, as appropriate, in the consolidated balance sheets and the changes in fair value are recorded in interest expense, net in the consolidated statements of operations. We include unrealized gains and losses on derivatives as a non-cash reconciling item in operating activities in the consolidated statements of cash flows. We include realized gains and losses on derivatives as a change in components of operating assets and liabilities in operating activities in the consolidated statements of cash flows. See Note 10, Derivative Instruments.

We recognize revenue from contracts with customers as we satisfy our performance obligations at a transaction price reflecting an amount of consideration based upon an estimated rate of return, net of cash incentives. We express this rate of return as the solar rate per kilowatt hour ("kWh") in the customer contract. The amount of revenue we recognize does not equal customer cash payments because we satisfy performance obligations ahead of cash receipt or evenly as we provide continuous access on a stand-ready basis to the solar energy system. We reflect the differences between revenue recognition and cash payments received in accounts receivable, other assets or deferred revenue, as appropriate. Revenue allocated to remaining performance obligations represents contracted revenue we have not yet recognized and includes deferred revenue as well as amounts that will be invoiced and recognized as revenue in future periods. Contracted but not yet recognized revenue was approximately $3.3 billion as of December 31, 2022, of which we expect to recognize approximately 4% over the next 12 months. We do not expect the annual recognition to vary significantly over approximately the next 20 years as the vast majority of existing solar service agreements have at least 20 years remaining, given the average age of the fleet of solar energy systems under contract is less than four years.

Certain customers may receive cash incentives. We defer recognition of the payment of these cash incentives and recognize them over the life of the contract as a reduction to revenue. The deferred payment is recorded in other assets for customers who receive the cash incentives under our lease and PPA agreements, and as a contra-liability in other long-term liabilities for customers who receive the cash incentives under our loan agreements.

*PPAs.*&nbsp;&nbsp;&nbsp;&nbsp;Customers purchase electricity from us under PPAs. Pursuant to ASC 606, we recognize revenue based upon the amount of electricity delivered as determined by remote monitoring equipment at solar rates specified under the PPAs. All customers must pass our credit evaluation process. The PPAs generally have a term of 20 or 25 years with an opportunity for customers to renew for up to an additional 10 years, via two five-year or one 10-year renewal options.

*Leases*.&nbsp;&nbsp;&nbsp;&nbsp;We are the lessor under lease agreements for solar energy systems and energy storage systems, which do not meet the definition of a lease under ASC 842 and are accounted for as contracts with customers under ASC 606. We recognize revenue on a straight-line basis over the contract term as we satisfy our obligation to provide continuous access to the solar energy system. All customers must pass our credit evaluation process. The lease agreements generally have a term of 20 or 25 years with an opportunity for customers to renew for up to an additional 10 years, via two five-year or one 10-year renewal options.

In most cases, we provide customers under our lease agreements a performance guarantee that each solar energy system will achieve a certain specified minimum solar energy production output, which is a significant proportion of its expected output. The specified minimum solar energy production output may not be achieved due to natural fluctuations in the weather or equipment failures from exposure and wear and tear outside of our control, among other factors. We determine the amount of the guaranteed output based on a number of different factors, including: (a) the specific site information related to the tilt of the panels, azimuth (a horizontal angle measured clockwise in degrees from a reference direction) of the panels, size of the system, and shading on site; (b) the calculated amount of available irradiance (amount of energy for a given flat surface facing a specific direction) based on historical average weather data and (c) the calculated amount of energy output of the solar energy system. While actual irradiance levels can significantly change year over year due to natural fluctuations in the weather, we expect the

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

levels to average out over the term of a lease and to approximate the levels used in determining the amount of the performance guarantee. Generally, weather fluctuations are the most likely reason a solar energy system may not achieve a certain specified minimum solar energy production output.

If the solar energy system does not produce the guaranteed production amount, we are required to refund a portion of the previously remitted customer payments, where the repayment is calculated as the product of (a) the shortfall production amount and (b) the dollar amount (guaranteed rate) per kWh that is fixed throughout the term of the contract. These remittances of a customer's payments, if needed, are payable as early as the first anniversary of the solar energy system's placed in service date and then every annual period thereafter. See Note 17, Commitments and Contingencies.

*Inventory Sales*.&nbsp;&nbsp;&nbsp;&nbsp;Inventory sales revenue represents revenue from the direct sale of inventory to our dealers or other parties. We recognize the related revenue under ASC 606 upon shipment. Shipping and handling costs are included in cost of revenue—inventory sales in the consolidated statements of operations.

*Solar Renewable Energy Certificates.*&nbsp;&nbsp;&nbsp;&nbsp;Each solar renewable energy certificate ("SREC") represents the environmental benefit of one megawatt hour (1,000 kWh) generated by a solar energy system. SRECs can be sold separate from the actual electricity generated by the renewable-based generation source. We account for the SRECs we generate from our solar energy systems as governmental incentives with no costs incurred to obtain them and do not consider those SRECs output of the underlying solar energy systems. We classify these SRECs as inventory held until sold and delivered to third parties. As we did not incur costs to obtain these governmental incentives, the inventory carrying value for the SRECs was $0 as of December 31, 2022 and 2021. We enter into economic hedges related to expected production of SRECs through forward contracts. While these fixed price forward contracts serve as an economic hedge against spot price fluctuations for the SRECs, the contracts do not qualify for hedge accounting and are not designated as cash flow hedges or fair value hedges. The contracts require us to physically deliver the SRECs upon settlement. We recognize the related revenue under ASC 606 upon satisfaction of the performance obligation to transfer the SRECs to the stated counterparty. Payments are typically received within one month of transferring the SREC to the counterparty. The costs related to the sales of SRECs are generally limited to broker fees (recorded in cost of revenue—other), which are only paid in connection with certain transactions. In certain circumstances we are required to purchase SRECs on the open market to fulfill minimum delivery requirements under our forward contracts.

*Cash Sales.*&nbsp;&nbsp;&nbsp;&nbsp;Cash sales revenue represents revenue from a customer's purchase of a solar energy system from us typically when purchasing a new home. We recognize the related revenue under ASC 606 upon verification of the home closing.

*Loans.*&nbsp;&nbsp;&nbsp;&nbsp;See discussion of loan revenue in the "*Loans*" section below.

*Other Revenue.*&nbsp;&nbsp;&nbsp;&nbsp;Other revenue includes certain state and utility incentives, revenue from the direct sale of solar energy systems and energy storage systems to customers with financing provided by us and sales of service plans and repair services. We recognize revenue from state and utility incentives in the periods in which they are earned. We recognize revenue from the direct sale of energy storage systems in the period in which the storage components are placed in service. Service plans are available to customers whose solar energy system was not originally sold by Sunnova. We recognize revenue from service plan contracts on a straight-line basis over the life of the contract, which is typically 10 years. We recognize revenue from repair services in the period in which the service was performed.

***Loans***

We offer a loan program, under which the customer finances the purchase of a solar energy system or energy storage system through a solar service agreement, typically for a term of 10, 15 or 25 years. We recognize cash payments received from customers on a monthly basis under our loan program (a) as interest income, to the extent attributable to earned interest on the contract that financed the customer's purchase of the solar energy system or energy storage system; (b) as a reduction of a note receivable on the balance sheet, to the extent attributable to a return of principal (whether scheduled or prepaid) on the contract that financed the customer's purchase of the solar energy system or energy storage system; and (c) as revenue, to the extent attributable to payments for operations and maintenance services provided by us. To qualify for the loan program, a customer must pass our credit evaluation process, which requires the customer to have a minimum FICO<sup>®</sup> score of 600 to 720 depending on certain circumstances, and we secure the loans with the solar energy systems or energy storage systems financed. The credit evaluation process is performed once for each customer at the time the customer is entering into the solar service agreement with us.

Our investments in solar energy systems and energy storage systems related to the loan program that are not yet placed in service are recorded in other assets in the consolidated balance sheets and are transferred to customer notes receivable upon

------

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

being placed in service. Customer notes receivable are recorded at amortized cost, net of an allowance for credit losses (as described below), in other current assets and customer notes receivable in the consolidated balance sheets. Accrued interest receivable related to our customer notes receivable is recorded in accounts receivable—trade, net in the consolidated balance sheets. Interest income from customer notes receivable is recorded in interest income in the consolidated statements of operations. The amortized cost of our customer notes receivable is equal to the principal balance of customer notes receivable outstanding and does not include accrued interest receivable. Customer notes receivable continue to accrue interest until they are written off against the allowance, which occurs when the balance is 180 days or more past due unless the balance is in the process of collection. Customer notes receivable are considered past due one day after the due date based on the contractual terms of the loan agreement. In all cases, customer notes receivable balances are placed on a nonaccrual status or written off at an earlier date when they are deemed uncollectible. Expected recoveries do not exceed the aggregate of amounts previously written off and expected to be written off. Accrued interest receivable for customer notes receivable placed on a nonaccrual status is recorded as a reduction to interest income. Interest received on such customer notes receivable is accounted for on a cash basis until the customer notes receivable qualifies for the return to accrual status. Customer notes receivable are returned to accrual status when there is no longer any principal or interest amounts past due and future payments are reasonably assured.

The allowance for credit losses is deducted from the customer notes receivable amortized cost to present the net amount expected to be collected. It is measured on a collective (pool) basis when similar risk characteristics (such as financial asset type, customer credit rating, contractual term and vintage) exist. In determining the allowance for credit losses, we identify customers with potential disputes or collection issues and consider our historical level of credit losses and current economic trends that might impact the level of future credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics, such as differences in underwriting standards. Expected credit losses are estimated over the contractual term of the loan agreements based on the best available data at the time and adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals and modifications unless either of the following applies: (a) we have a reasonable expectation at the reporting date that a troubled debt restructuring will be executed with an individual customer or (b) the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancelable by us. See Note 7, Customer Notes Receivable.

***Deferred Revenue***

Deferred revenue consists of amounts for which the criteria for revenue recognition have not yet been met and includes (a) payments for unfulfilled performance obligations which will be recognized on a straight-line basis over the remaining term of the respective solar service agreements, net of any cash incentives earned by the customers, (b) down payments and partial or full prepayments from customers and (c) differences due to the timing of energy production versus billing for certain types of PPAs. Deferred revenue was $106.8 million as of December 31, 2020. The following table presents the detail of deferred revenue as recorded in other current liabilities and other long-term liabilities in the consolidated balance sheets:

---

| Solar receivables | 4602 | 4864 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total (1) | $615623 | $297819 |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) Of this amount, $30.2 million and $15.3 million is recorded in other current liabilities as of December 31, 2022 and 2021, respectively.

During the years ended December 31, 2022 and 2021, we recognized revenue of $16.0 million and $8.4 million, respectively, from amounts recorded in deferred revenue at the beginning of the respective years.

***Performance Guarantee Obligations***

In most cases, we guarantee certain specified minimum solar energy production output under our leases and loan agreements, generally over a term between 10 and 25 years. The amounts are generally measured and credited to the customer's account as early as the first anniversary of the solar energy system's placed in service date and then every annual period thereafter. We monitor the solar energy systems to ensure these outputs are achieved. We evaluate if any amounts are due to our customers based upon not meeting the guaranteed solar energy production outputs at each reporting period end. For leases,

------

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

these estimated amounts are recorded as a reduction to revenues from customers and a current or long-term liability, as applicable. For loans, these estimated amounts are recorded as an increase to cost of revenue—other and a current or long-term liability, as applicable. See Note 17, Commitments and Contingencies.

***Property and Equipment***

*Solar Energy Systems and Energy Storage Systems.*&nbsp;&nbsp;&nbsp;&nbsp;Depreciation and amortization of solar energy systems and energy storage systems are calculated using the straight-line method over the estimated useful lives of the solar energy systems and energy storage systems and are recorded in cost of revenue—depreciation. While solar energy systems and energy storage systems are in the design, construction and installation stages prior to being placed in service, the development of the systems is accounted for through construction in progress. The components of the design, construction and installation of the solar energy systems and energy storage systems are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Dealer's costs (engineering, procurement and construction)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*•* Direct costs (costs directly related to a solar energy system or energy storage system)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*•* Indirect costs (costs incurred in the design, construction and installation of the solar energy system or energy storage system but not directly associated with a particular asset)

Solar energy systems and energy storage systems are carried at the cost of acquisition or construction (including design and installation) less certain utility rebates and federal and state tax incentives (including federal investment tax credits, known as "Section 48(a) ITCs") and are depreciated over the useful lives of the assets. We account for the Section 48(a) ITCs in accordance with the deferral gross up method, thus reducing the cost basis of the qualifying solar energy systems and energy storage systems by the rate applicable to Section 48(a) ITCs. However, as discussed in Note 11, Income Taxes, we have a full valuation allowance, which is recorded against deferred income taxes and requires the gross up of the basis of the qualifying solar energy systems and energy storage systems back to the full value. Depreciation begins when a solar energy system or energy storage system is placed in service. Costs associated with repair and maintenance of a solar energy system or energy storage system are expensed as incurred. Costs associated with improvements to a solar energy system or energy storage system, which extend the life, increase the capacity or improve the efficiency of the systems, are capitalized and depreciated over the remaining life of the asset.

*Property and Equipment, Excluding Solar Energy Systems and Energy Storage Systems*.&nbsp;&nbsp;&nbsp;&nbsp;Property and equipment, including information technology system projects, computers and equipment, leasehold improvements, furniture and fixtures, vehicles and other property and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation and amortization are calculated using the straight-line method over the estimated useful lives of the respective assets and are recorded in general and administrative expense. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful lives. Upon disposition, the cost and related accumulated depreciation of the assets are removed from property and equipment and the resulting gain or loss is reflected in the consolidated statements of operations. Repair and maintenance costs are expensed as incurred.

***Acquisitions***

Business combinations are accounted for using the acquisition method of accounting in accordance with ASC 805, *Business Combinations*, as amended by Accounting Standards Update ("ASU") No. 2017-01, *Business Combinations: Clarifying the Definition of a Business*. The purchase price of an acquisition is measured at the estimated fair value of the assets acquired, equity instruments issued and liabilities assumed at the acquisition date. Any noncontrolling interests acquired are also initially measured at fair value. Costs that are directly attributable to the acquisition are expensed as incurred to general and administrative expense. We recognize goodwill if the aggregate fair value of the total purchase consideration and the noncontrolling interests is in excess of the aggregate fair value of the assets acquired and liabilities assumed. We may engage third-party valuation firms to assist in determining the fair values. The operating results of an acquired business are included in our results of operations from the date of acquisition. We have up to one year from the acquisition date to complete the fair value purchase price allocation. See Note 12, Acquisitions.

Asset acquisitions are measured based on the cost to us, including transaction costs. Asset acquisition costs, or the consideration transferred by us, are assumed to be equal to the fair value of the net assets acquired. If the consideration transferred is cash, measurement is based on the amount of cash we paid to the seller, as well as transaction costs incurred. Consideration given in the form of non-monetary assets, liabilities incurred or equity instruments issued is measured based on either the cost to us or the fair value of the assets or net assets acquired, whichever is more clearly evident. The cost of an asset acquisition is allocated to the assets acquired based on their estimated fair values. Goodwill is not recognized in an asset acquisition.

***Intangibles***

Our purchased intangible assets are stated at cost less accumulated amortization. Our intangible assets acquired from a business combination or asset acquisition are stated at the estimated fair value on the date of the acquisition less accumulated amortization (see Note 12, Acquisitions). We amortize intangible assets to general and administrative expense using the straight-line method. The following table presents the detail of intangible assets as recorded in other assets in the consolidated balance sheets:

***Goodwill***

Goodwill represents the excess of the purchase price over the fair value of assets acquired and liabilities assumed. The purchase price is allocated using the information currently available, and may be adjusted, up to one year from the acquisition date, after obtaining more information regarding, among other things, asset valuations, liabilities assumed and revisions to preliminary estimates. Goodwill is reviewed for impairment at least annually or whenever events or changes in circumstances indicate the carrying amount may be impaired. When assessing goodwill for impairment, we use qualitative and if necessary, quantitative methods in accordance with GAAP. In 2022, we utilized a qualitative assessment and concluded it was more likely than not the fair value was greater than the carrying amount. As such, no further testing is required.

***Deferred Financing Costs***

Deferred financing costs are capitalized and amortized to interest expense, net over the term of the related debt using the effective interest method for term loans or the straight-line method for revolving credit facilities. The unamortized balance of deferred financing costs is recorded in current portion of long-term debt, current portion of long-term debt—affiliates, long-term debt, net and long-term debt, net—affiliates (see Note 9, Long-Term Debt) for term loans or in other current assets and

***Asset Retirement Obligation ("ARO")***

We have AROs arising from contractual requirements to perform certain asset retirement activities at the time the solar energy systems are disposed. We recognize an ARO at the point an obligating event takes place, typically when the solar energy system is placed in service. An asset is considered retired when it is permanently taken out of service, such as through a sale or disposal.

The liability is initially measured at fair value (as a Level 3 measurement) based on the present value of estimated removal and restoration costs and subsequently adjusted for changes in the underlying assumptions and for accretion expense. The accretion expense is recognized in general and administrative expense in the consolidated statements of operations. The corresponding asset retirement costs are capitalized as part of the carrying amount of the solar energy system and depreciated over the solar energy system's remaining useful life. See Note 6, AROs.

***Warranty Obligations***

In connection with our solar service agreements, we warrant the solar energy systems against defects in workmanship, against component or materials breakdowns and against any damages to rooftops during the installation process. The dealers' warranties on the workmanship, including work during the installation process, and the manufacturers' warranties over component parts have a range of warranty periods which are generally 10 to 25 years. As of December 31, 2022 and 2021, a warranty reserve of $3.0 million and $815,000, respectively, is recorded in other long-term liabilities in the consolidated balance sheets.

***Advertising Costs***

We expense advertising costs as they are incurred to general and administrative expense in the consolidated statements of operations. We recognized advertising expense of $2.5 million, $1.9 million and $195,000 during the years ended December 31, 2022, 2021 and 2020, respectively.

***Defined Contribution Plan***

In April 2015, we established the Sunnova Energy Corporation 401(k) Profit Sharing Plan ("401(k) plan") available to employees who meet the 401(k) plan's eligibility requirements. The 401(k) plan allows participants to contribute a percentage of their compensation to the 401(k) plan up to the limits set forth in the Internal Revenue Code. We may make additional discretionary contributions to the 401(k) plan as a percentage of total participant contributions, subject to established limits. Participants are fully vested in their contributions and any safe harbor matching contributions we make. We made safe harbor matching contributions of $1.8 million, $1.3 million and $820,000 during the years ended December 31, 2022, 2021 and 2020, respectively, which are recorded in general and administrative expense in the consolidated statements of operations.

***Income Taxes***

We account for income taxes under an asset and liability approach. Deferred income taxes reflect the impact of temporary differences between assets and liabilities recognized for financial reporting purposes and the amounts recognized for income tax reporting purposes, net operating loss, carryforwards, and other tax credits measured by applying currently enacted tax laws. A valuation allowance is provided when necessary to reduce deferred tax assets to an amount that is more likely than not to be realized.

<u>[**Table of Contents**](#id44f78bea0d74c328827c5cbc12059f6_25)</u>

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

We determine whether a tax position taken in a filed tax return, planned to be taken in a future tax return or claim, or otherwise subject to interpretation, is more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position, or prospectively approved when such approval may be sought in advance. We use a two-step approach to recognize and measure uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the available evidence indicates it is more likely than not the position will be sustained upon tax authority examination, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit or obligation as the largest amount that is more than 50% likely of being realized upon ultimate settlement. See Note 11, Income Taxes.

***Comprehensive Income (Loss)***

We are required to report comprehensive income (loss), which includes net income (loss) as well as other comprehensive income (loss). There were no differences between comprehensive loss and net loss as reported in the consolidated statements of operations for the periods presented.

***Impairment of Long-Lived Assets***

Long-lived assets, such as property and equipment, are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset be tested for possible impairment, we first compare undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, impairment is recognized to the extent the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals as considered necessary. Impairment charges are recorded in operations and maintenance expense for solar energy systems that relate to revenue from contracts with customers and general and administrative expense for all other property and equipment and other long-lived assets.

***Segment Information***

Operating segments are defined as components of a company about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. Our chief operating decision maker is the chief executive officer. Based on the financial information presented to and reviewed by our chief operating decision maker in deciding how to allocate resources and in assessing performance, we have determined we have a single reportable segment: solar energy products and services. Our principal operations, revenue and decision-making functions are located in the U.S.

***Basic and Diluted Net Income (Loss) Per Share***

Our basic net income (loss) per share attributable to stockholders is calculated by dividing the net income (loss) attributable to stockholders by the weighted-average number of shares of common stock outstanding for the period. Our diluted net income (loss) per share attributable to stockholders is calculated by giving effect to all potential common stock equivalents outstanding for the period determined using the treasury stock method or the if-converted method, as applicable. During periods in which we incur a net loss attributable to stockholders, stock options and restricted stock units are considered to be common stock equivalents but are excluded from the calculation of diluted net loss per share attributable to stockholders as the effect is antidilutive. See Note 16, Basic and Diluted Net Loss Per Share.

***Equity-Based Compensation***

We account for equity-based compensation, which requires the measurement and recognition of compensation expense related to the fair value of equity-based compensation awards. Equity-based compensation expense includes the compensation cost for all share-based awards granted to employees, consultants and members of our board of directors (our "Board") based on the grant date fair value estimate. This also applies to awards modified, repurchased or canceled during the periods reported. We use the Black-Scholes option-pricing model to measure the fair value of stock options at the measurement date. We use the closing price of our common stock on the grant date to measure the fair value of restricted stock units at the measurement date. We account for forfeitures as they occur. Equity-based compensation expense is recorded in general and administrative expense in the consolidated statements of operations. See Note 15, Equity-Based Compensation.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

***Redeemable Noncontrolling Interests and Noncontrolling Interests***

Noncontrolling interests represent third-party interests in the net assets of certain consolidated subsidiaries (the "tax equity entities"). For these tax equity entities, we have determined the appropriate methodology for calculating the noncontrolling interest balances that reflects the substantive economic arrangements in the operating agreements is a balance sheet approach using the hypothetical liquidation at book value ("HLBV") method. Under the HLBV method, the amounts reported as noncontrolling interests in the consolidated balance sheets represent the amounts third-party investors would hypothetically receive at each balance sheet date under the liquidation provisions of the operating agreements, assuming the net assets of the subsidiaries were liquidated at amounts determined in accordance with GAAP and distributed to the investors. The noncontrolling interest balances in these subsidiaries are reported as a component of equity in the consolidated balance sheets. The amount of income or loss allocated to noncontrolling interests in the results of operations for the subsidiaries using HLBV are determined as the difference in the noncontrolling interest balances in the consolidated balance sheets at the start and end of each reporting period, after taking into account any capital transactions between the subsidiaries and the third-party investors. Factors used in the HLBV calculation include GAAP income (loss), taxable income (loss), capital contributions, investment tax credits, distributions and the stipulated targeted investor return specified in the subsidiaries' operating agreements. Changes in these factors could have a significant impact on the amounts that investors would receive upon a hypothetical liquidation. The use of the HLBV method to allocate income (loss) to the noncontrolling interest holders may create volatility in the consolidated statements of operations as the application of HLBV can drive changes in net income or loss attributable to noncontrolling interests from period to period. We classify certain noncontrolling interests with redemption features that are not solely within our control outside of permanent equity in the consolidated balance sheets. Redeemable noncontrolling interests are reported using the greater of the carrying value at each reporting date as determined by the HLBV method or the estimated redemption value at the end of each reporting period. Estimating the redemption value of the redeemable noncontrolling interests requires the use of significant assumptions and estimates, such as projected future cash flows at the time the redemption feature can be exercised. The redeemable noncontrolling interests and noncontrolling interests are recorded net of related issuance costs and net of the basis difference in the solar energy systems transferred to the tax equity entities in the consolidated balance sheets. This basis difference is reflected as equity in subsidiaries attributable to parent in the consolidated statements of redeemable noncontrolling interests and equity.

***New Accounting Guidance***

New accounting pronouncements are issued by the FASB or other standard setting bodies and are adopted as of the specified effective date.

In March 2022, the FASB issued Accounting Standards Update ("ASU") No. 2022-02, *Financial Instruments—Credit Losses: Troubled Debt Restructurings and Vintage Disclosures*, to eliminate the accounting guidance for troubled debt restructurings while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. This ASU is effective for annual and interim reporting periods beginning in January 2023. We adopted this ASU in January 2023 and determined it did not have a significant impact on our consolidated financial statements and related disclosures.

---

The amounts included in the above table for solar energy systems and energy storage systems and substantially all the construction in progress relate to our customer contracts (including PPAs and leases). These assets had accumulated depreciation of $360.1 million and $264.6 million as of December 31, 2022 and 2021, respectively.

**(4) Natural Disaster Losses**

We have insurance coverage related to property damage and business interruption. When a solar energy system is damaged by a natural disaster, we impair all or a portion of the net book value to operations and maintenance expense in the period for which the amount is probable and can be reasonably estimated. Insurance proceeds for property damage, up to the amount of impairment expense recorded for property damage, are estimated and recorded as a receivable (recorded in accounts receivable—other in the consolidated balance sheet) and a reduction to operations and maintenance expense when the receipt of the proceeds is deemed probable. Insurance proceeds for property damage that exceed the amount of impairment expense recorded and insurance proceeds related to business interruption are recorded when received, as a reduction to operations and maintenance expense. Costs incurred to repair or replace a solar energy system are capitalized (recorded in property and equipment, net in the consolidated balance sheet) and are classified as an investing cash outflow in the consolidated statement of cash flows. Insurance proceeds received for property damage are classified as an investing cash inflow in the consolidated statement of cash flows. Insurance proceeds received for business interruption are classified as an operating cash inflow in the consolidated statement of cash flows.

*Hurricane Fiona in Puerto Rico*.&nbsp;&nbsp;&nbsp;&nbsp;In September 2022, Hurricane Fiona made landfall in Puerto Rico causing significant wind and water damage to the island's infrastructure, residences and businesses. A majority of Puerto Rico was left without electrical power. In addition, other basic utility and infrastructure services (such as water, communications, ports and other transportation networks) were severely curtailed. We had no material damages to our solar energy systems and energy storage systems.

*Hurricane Ian in Florida*.&nbsp;&nbsp;&nbsp;&nbsp;In September 2022, Hurricane Ian made landfall in Florida causing catastrophic wind and water damage to the state's infrastructure, residences and businesses. We had no material damages to our solar energy systems and energy storage systems.

During the year ended December 31, 2022, we incurred (a) $633,000 related to third-parties helping our customers, primarily restarting batteries and (b) $532,000 related to employees performing similar type work or other work related to the

**(6) AROs**

AROs consist primarily of costs to remove solar energy system assets and costs to restore the solar energy system sites to the original condition, which we estimate based on current market rates. For each solar energy system, we recognize the fair value of the ARO as a liability and capitalize that cost as part of the cost basis of the related solar energy system. The related assets are depreciated on a straight-line basis over 30 years, which is the estimated average time a solar energy system will be installed in a location before being removed, and the related liabilities are accreted to the full value over the same period of time. We revise our estimated future liabilities based on recent actual experiences, including third party cost estimates, average size of solar energy systems and inflation rates, which we evaluate at least annually. Changes in our estimated future liabilities are recorded as either a reduction or addition in the carrying amount of the remaining unamortized asset and the ARO and either decrease or increase our depreciation and accretion expense amounts prospectively. The following table presents the changes in AROs as recorded in other long-term liabilities in the consolidated balance sheets:

As of December 31, 2022 and 2021, we invested $382.6 million and $238.8 million, respectively, in loan solar energy systems and energy storage systems not yet placed in service. For the years ended December 31, 2022 and 2021, interest income related to our customer notes receivable was $56.4 million and $33.7 million, respectively. As of December 31, 2022 and 2021, accrued interest receivable related to our customer notes receivable was $10.2 million and $3.5 million, respectively. As of December 31, 2022 and 2021, there was $12.6 million and $0, respectively, of customer notes receivable not accruing interest and there was $278,000 and $0, respectively, of allowance recorded for loans on nonaccrual status. For the years ended December 31, 2022 and 2021, interest income of $0 was recognized for loans on nonaccrual status and accrued interest receivable of $514,000 and $0, respectively, was written off by reversing interest income.

We consider the performance of our customer notes receivable portfolio and its impact on our allowance for credit losses. We also evaluate the credit quality based on the aging status and payment activity. The following table presents the aging of the amortized cost of customer notes receivable:

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**(8) Investments in Solar Receivables**

In November 2021, one of our wholly-owned subsidiaries entered into a Master Lease Agreement (the "EAH Master Lease") with Energy Asset HoldCo LLC, a Delaware limited liability company and subsidiary of Lennar ("EAH Lessor"), to lease two pools of solar energy systems and assume the related PPA and lease obligations from EAH Lessor. In exchange for the right to receive future customer cash flows as well as certain credits, rebates and incentives (including SRECs) under those pooled agreements, we made an upfront payment to Lennar consisting of $35.0 million in initial cash consideration and 1,027,409 shares of our common stock for net consideration of $79.4 million. Pursuant to the terms of the EAH Master Lease, additional pools of solar energy systems may also be leased from EAH Lessor in the future in exchange for upfront lease payments. We will evaluate additional systems on a quarterly basis and, if eligible, are required to tranche the systems under the EAH Master Lease until March 2025.

We established criteria for eligibility that ensures each solar energy system is operational, in service, in good standing and no liens or encumbrances exist. We continue to provide all operations, maintenance and asset management services to EAH Lessor related to the leased solar energy systems. EAH Lessor's residual interest in the solar energy systems comes from any customer renewal exercised after the twentieth anniversary of the contract term of the solar service agreement, the remainder of the useful life of the solar energy system after the termination of the solar service agreement and any tax incentives (including Section 48(a) ITCs) associated with the ownership of the solar energy system.

As the EAH Master Lease does not constitute or contain a lease under the criteria specified by ASC 842, the purchase of EAH Lessor's future revenue has been accounted for as an acquisition of financial assets and we have elected the fair value option under ASC 825. For the purposes of establishing the fair value of our investments in solar receivables, our analysis considers cash flows beginning in September 2021 (the effective date of the transaction). We estimated the fair value of our investments in solar receivables to be $84.3 million on the transaction date. As of December 31, 2022 and 2021, we recorded $72.2 million and $82.7 million, respectively, of investments in solar receivables, of which $7.1 million and $6.8 million, respectively, is recorded in other current assets and $65.1 million and $75.9 million, respectively, is recorded in other assets in the consolidated balance sheets. During the years ended December 31, 2022 and 2021, we recorded a gain on our investments in solar receivables of $1.1 million and $2.4 million, respectively, in the consolidated statements of operations.

*Availability.*&nbsp;&nbsp;&nbsp;&nbsp;As of December 31, 2022, we had $174.3 million of available borrowing capacity under the TEPH revolving credit facility. There was no available borrowing capacity under any of our other financing arrangements. As of December 31, 2022, we were in compliance with all debt covenants under our financing arrangements.

*Weighted Average Effective Interest Rates.*&nbsp;&nbsp;&nbsp;&nbsp;The weighted average effective interest rates disclosed in the table above are the weighted average stated interest rates for each debt instrument plus the effect on interest expense for other items classified as interest expense, such as the amortization of deferred financing costs, amortization of debt discounts and commitment fees on unused balances for the period of time the debt was outstanding during the indicated periods.

*SEI Debt*.&nbsp;&nbsp;&nbsp;&nbsp;In May 2021, we issued and sold an aggregate principal amount of $575.0 million of our 0.25% convertible senior notes ("0.25% convertible senior notes") in a private placement at a discount to the initial purchasers of 2.5%, for an aggregate purchase price of $560.6 million. The 0.25% convertible senior notes mature in December 2026 unless earlier redeemed, repurchased or converted. In connection with the pricing of the 0.25% convertible senior notes, we used proceeds of $91.7 million to enter into privately negotiated capped call transactions, which are expected to reduce the potential dilution to common shares and/or offset potential cash payments that could be required to be made in excess of the principal amount upon any exchange of notes. Such reduction and/or offset is subject to a cap initially equal to $60.00 per share, subject to adjustments. The capped call transactions cover, subject to customary adjustments, the number of shares of our common stock initially underlying the 0.25% convertible senior notes. As the capped call transactions meet certain accounting criteria, they are classified as stockholders' equity and therefore, are recorded in additional paid-in capital—common stock in the consolidated balance sheet and are not accounted for as derivatives.

In August 2022, we issued and sold an aggregate principal amount of $600.0 million of our 2.625% convertible senior notes ("2.625% convertible senior notes") in a private placement at a discount to the initial purchasers of 2.5%, for an aggregate purchase price of $585.0 million. The 2.625% convertible senior notes mature in February 2028 unless earlier redeemed, repurchased or converted. In connection with the pricing of the 2.625% convertible senior notes, we used proceeds of $48.4 million to enter into privately negotiated capped call transactions, which are expected to reduce the potential dilution to common shares and/or offset potential cash payments that could be required to be made in excess of the principal amount upon any exchange of notes. Such reduction and/or offset is subject to a cap initially equal to $34.24 per share, subject to adjustments. The capped call transactions cover, subject to customary adjustments, the number of shares of our common stock initially underlying the 2.625% convertible senior notes. As the capped call transactions meet certain accounting criteria, they are classified as stockholders' equity and therefore, are recorded in additional paid-in capital—common stock in the consolidated balance sheet and are not accounted for as derivatives.

*Sunnova Energy Corporation Debt*.&nbsp;&nbsp;&nbsp;&nbsp;In August 2020, Sunnova Energy Corporation entered into an arrangement to finance $2.8 million in directors and officers insurance premiums at an annual interest rate of 4.25% over seven months. In October 2020, Sunnova Energy Corporation entered into an arrangement to finance $1.4 million in property insurance premiums at an annual interest rate of 4.25% over five months. In August 2021, Sunnova Energy Corporation issued and sold an aggregate principal amount of $400.0 million of 5.875% senior notes ("5.875% senior notes") at a discount to the initial purchasers of 1.24%, for an aggregate purchase price of $395.0 million. The 5.875% senior notes mature in September 2026 and are initially guaranteed on a senior unsecured basis by SEI and a wholly-owned subsidiary of Sunnova Energy Corporation.

*EZOP Debt*.&nbsp;&nbsp;&nbsp;&nbsp;In April 2017, EZOP, a special purpose entity, entered into a secured revolving credit facility with Credit Suisse AG, New York Branch, as agent, and the lenders party thereto, for an aggregate commitment amount of $100.0 million with a maturity date of April 2019. In August 2017, the aggregate commitment amount was reduced to $70.0 million and in March 2019, the aggregate commitment amount was increased to $200.0 million. The EZOP revolving credit facility allows for the pooling and transfer of eligible loans on a non-recourse basis subject to certain limited exceptions. The proceeds of the loans under the EZOP revolving credit facility are available to purchase or otherwise acquire loans (which we originated) directly from Sunnova Asset Portfolio 7 Holdings, LLC ("AP7H") pursuant to a sale and contribution agreement, fund certain reserve accounts that are required to be maintained by EZOP in accordance with the credit agreement and pay fees and expenses incurred in connection with the EZOP revolving credit facility. The amount available for borrowings at any one time under the EZOP revolving credit facility is limited to a borrowing base amount determined at each borrowing and calculated based on the aggregate discounted present value of remaining payments owed to EZOP in respect of the loans transferred to EZOP.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

Interest on the borrowings under the EZOP revolving credit facility is due monthly. Borrowings under the EZOP revolving credit facility bear interest at an annual rate equal to the weighted-average cost to the lender of any commercial paper (to the extent the lender funds an advance by issuing commercial paper) plus 3.50% during the commitment availability period and 4.50% after the commitment availability period. In March 2019, we amended the EZOP revolving credit facility to, among other things, adjust the interest rate on borrowings to an annual rate of adjusted London interbank offered rate ("LIBOR") plus either 2.15% or 3.15% per annum depending on the date of the most recent takeout transaction in respect of assets securing the EZOP revolving credit facility and extend the maturity date from April 2019 to November 2022. In December 2019, we further amended the EZOP revolving credit facility to, among other things, adjust the interest rate on borrowings to an annual rate of adjusted LIBOR plus either 2.35% or 3.35% per annum depending on the date of the most recent takeout transaction in respect of assets securing the EZOP revolving credit facility. In June 2020, proceeds from the HELIV Notes (as defined below) were used to repay $149.3 million in aggregate principal amount outstanding of EZOP debt. In October 2020, proceeds from the AP8 revolving credit facility were used to repay $28.0 million in aggregate principal amount outstanding of EZOP debt. In February 2021, proceeds from the HELV Notes (as defined below) were used to repay $107.3 million in aggregate principal amount outstanding of EZOP debt. In March 2021, we amended the EZOP revolving credit facility to, among other things, (a) extend the maturity date to November 2023 and (b) increase the uncommitted maximum facility amount from $200.0 million to $350.0 million. In July 2021, proceeds from the HELVI Notes (as defined below) were used to repay $144.0 million in aggregate principal amount outstanding of EZOP debt. In June 2022, we amended the EZOP revolving credit facility to, among other things, (a) extend the scheduled commitment termination date to May 2024, (b) extend the facility maturity date to November 2024, (c) increase the aggregate commitment amount from $200.0 million to $400.0 million, subject to reductions based on the outstanding principal balance of advances over certain time periods, (d) increase the uncommitted maximum facility amount from $350.0 million to $475.0 million, (e) modify the interest rate on borrowings from accruing based on LIBOR to accruing based on Term SOFR (as defined by such revolving credit facility), plus a Term SOFR (as defined by such revolving credit facility) spread adjustment, (f) add an amortization event related to certain of our subsidiaries ceasing to originate solar loans (subject to certain thresholds, time periods and exceptions set forth therein), (g) add concentration limits for solar loans (1) with obligors with credit scores below certain thresholds and (2) for which the original principal balance exceeds a certain threshold and (h) modify eligibility requirements for solar loans to increase the permitted maximum original principal balance. In July 2022, we amended the EZOP revolving credit facility to, among other things, increase the uncommitted maximum facility amount from $475.0 million to $535.0 million until the earlier to occur of (a) September 29, 2022 and (b) the date upon which a specific sale of borrowing base assets and a related prepayment of outstanding debt thereunder occurs, upon the occurrence of which the uncommitted maximum facility amount will return to $475.0 million. In August 2022, we amended the EZOP revolving credit facility to, among other things, (a) increase the aggregate commitment amount from $400.0 million to $450.0 million, (b) increase the uncommitted maximum facility amount from $535.0 million to $585.0 million, (c) amend certain provisions addressing the allocation of advances and principal payments among the lenders, (d) amend certain provisions addressing lender consent rights and related matters and (e) include certain provisions addressing service incentives and related matters. In August 2022, proceeds from the HELIX Notes (as defined below) were used to repay $151.0 million in aggregate principal amount of outstanding EZOP debt. In September 2022, we further amended the EZOP revolving credit facility to, among other things, (a) decrease the uncommitted maximum facility amount from $585.0 million to $575.0 million and (b) amend certain provisions related to the agent's allocation of certain payments made to the lenders. In November 2022, proceeds from the HELX Notes (as defined below) were used to repay $150.0 million in aggregate principal amount of outstanding EZOP debt.

The EZOP revolving credit facility requires EZOP to pay a fee based on the daily unused portion of the commitments under the EZOP revolving credit facility. Payments from the loans will be deposited into accounts established pursuant to the EZOP revolving credit facility and applied in accordance with a cash waterfall in the manner specified in the EZOP revolving credit facility. EZOP is also required to maintain certain reserve accounts for the benefit of the lenders under the EZOP revolving credit facility, each of which must remain funded at all times to the levels specified in the credit agreement. In connection with the EZOP revolving credit facility, certain of our affiliates receive a fee for managing and servicing the solar loan agreements and related solar energy systems pursuant to management and servicing agreements. In addition, Sunnova Energy Corporation has guaranteed (a) the manager's obligations to manage the solar loan agreements and related solar energy systems pursuant to the management agreement, (b) the servicer's obligations to service the solar loan agreements and related solar energy systems pursuant to the servicing agreement, (c) AP7H's obligations to repurchase or substitute certain ineligible solar loans sold to EZOP pursuant to certain sale and contribution agreements and (d) certain indemnification obligations related to its affiliates in connection with the EZOP revolving credit facility, but does not provide a general guarantee of the creditworthiness of the assets of EZOP pledged as the collateral for the EZOP revolving credit facility. Under the limited guarantee, Sunnova Energy Corporation is subject to certain financial covenants regarding tangible net worth, working capital and restrictions on the use of proceeds from the EZOP revolving credit facility.

*HELII Debt*.&nbsp;&nbsp;&nbsp;&nbsp;In November 2018, we pooled and transferred eligible solar energy systems and the related asset receivables into HELII, a special purpose entity, that issued $202.0 million in aggregate principal amount of Series 2018-1

------

Class A solar asset-backed notes and $60.7 million in aggregate principal amount of Series 2018-1 Class B solar asset-backed notes (collectively, the "HELII Notes") with a maturity date of July 2048. The HELII Notes were issued at a discount of 0.02% for Class A and 0.02% for Class B and bear interest at an annual rate equal to 4.87% and 7.71%, respectively. The cash flows generated by these solar energy systems are used to service the semi-annual principal and interest payments on the HELII Notes and satisfy HELII's expenses, and any remaining cash can be distributed to Helios Depositor II, LLC, HELII's sole member. In connection with the HELII Notes, certain of our affiliates receive a fee for managing and servicing the solar energy systems pursuant to management and servicing agreements. In addition, Sunnova Energy Corporation has guaranteed (a) the manager's obligations to manage the solar energy systems pursuant to the management agreement, (b) the servicer's obligations to service the solar energy systems pursuant to the servicing agreement and (c) Sunnova ABS Holdings, LLC's obligations to repurchase or substitute certain ineligible solar energy systems eventually sold to HELII pursuant to the sale and contribution agreement. HELII is also required to maintain certain reserve accounts for the benefit of the holders of the HELII Notes, each of which must remain funded at all times to the levels specified in the HELII Notes. The indenture requires HELII to track the DSCR of (a) the amount of certain payments received from customers, certain performance based incentives, certain energy credits and any applicable insurance proceeds as of a specific date to (b) interest and scheduled principal due on the HELII Notes as of such date with the potential to enter into an early amortization period if the DSCR drops below a certain threshold. The holders of the HELII Notes have no recourse to our other assets except as expressly set forth in the HELII Notes.

*RAYSI Debt*.&nbsp;&nbsp;&nbsp;&nbsp;In March 2019, we pooled and transferred eligible solar energy systems and the related asset receivables into RAYSI, a special purpose entity, that issued $118.1 million in aggregate principal amount of Series 2019-1 Class A solar asset-backed notes with a maturity date of April 2044 and $15.0 million in aggregate principal amount of Series 2019-1 Class B solar asset-backed notes with a maturity date of April 2034.

*TEPH Debt*.&nbsp;&nbsp;&nbsp;&nbsp;In September 2019, TEPH, a wholly-owned subsidiary of SEI, entered into a revolving credit facility with Credit Suisse AG, New York Branch, as administrative agent, and the lenders party thereto, for an aggregate committed amount of $100.0 million with a maturity date of November 2022. The TEPH revolving credit facility allows for borrowings based on the aggregate value of solar assets owned by subsidiaries of TEPH subject to certain excess concentration limitations. The proceeds from the TEPH revolving credit facility are available for funding certain reserve accounts required by the TEPH revolving credit facility, making distributions to the parent of TEPH and paying fees incurred in connection with closing the TEPH revolving credit facility. The TEPH revolving credit facility is non-recourse to SEI and is secured by net cash flows from PPAs and leases available to the borrower after distributions to tax equity investors and payment of certain operating, maintenance and other expenses. Sunnova Energy Corporation guarantees the performance of certain affiliates who manage the collateral related to the TEPH revolving credit facility as well as certain indemnity and repurchase obligations. Under the limited guarantee, Sunnova Energy Corporation is subject to certain financial covenants regarding tangible net worth, working capital and restrictions on the use of proceeds from the facility. In addition, TEPH's obligations under the TEPH revolving credit facility are guaranteed by certain subsidiaries of TEPH. In December 2019, we amended the TEPH revolving credit facility to, among other things, (a) modify the borrowing base eligibility criteria for certain solar assets related to the timing of the expected first payments from such solar assets, (b) modify the calculation of the amount required to be deposited into the liquidity reserve account, (c) delay the application of concentration limits for an additional 90 days, (d) temporarily increase the borrowing base applied to certain solar assets and (e) include additional provisions regarding qualified financial contract rules.

Borrowings under the TEPH revolving credit facility are made in Class A loans and Class B loans. The TEPH revolving credit facility has an advance rate equal to approximately 60% of the value of the solar projects in the portfolio that have not yet begun construction and 80% of the value of the solar projects that have reached substantial completion. Interest on the borrowings under the TEPH revolving credit facility is due quarterly. Borrowings under the TEPH revolving credit facility initially bore interest at an annual rate of either LIBOR divided by a percentage equal to 100% minus a reserve percentage or a base rate (defined as, for any day, a rate of interest per annum equal to the highest of (a) the prime rate for such day and (b) the sum of the weighted average of the rates on overnight federal funds transactions with members of the federal reserve system arranged by federal funds brokers as published for such day plus 0.50%), plus a margin of between 2.90% and 4.30%, which varies based on criteria including (a) whether the availability period has expired, (b) whether a takeout transaction has occurred in the last 18 months and (c) the ratio of Class A loans to Class B loans outstanding at such time.

In January 2020, we amended the TEPH revolving credit facility to, among other things, (a) allow a wholly-owned subsidiary of TEPH to transfer projects and other solar assets to tax equity funds owned by TEPH and (b) upon the full repayment and termination of another revolving credit facility, remove all cross-defaults and cross-collateralization between such other revolving credit facility and the TEPH revolving credit facility. In February 2020, we amended the TEPH revolving credit facility to, among other things, (a) increase the aggregate commitment amount from $100.0 million to $200.0 million and (b) increase the uncommitted maximum facility amount from $150.0 million to $200.0 million. In March 2020, we amended the TEPH revolving credit facility to, among other things, (a) increase the uncommitted maximum facility amount from $200.0 million to $400.0 million, with all of the increased amount coming from Class A lenders on an uncommitted basis, (b) increase both the Class A and Class B interest rates by 0.40% and (c) modify the borrowing base calculation to shift a portion of the borrowing base from Class B to Class A lenders. In May 2020, we amended the TEPH revolving credit facility to, among other things, (a) increase the aggregate commitment amount from $200.0 million to $390.0 million and (b) increase the unused line fee on such committed amounts. In June 2020, we amended the TEPH revolving credit facility to, among other things, (a) increase the aggregate commitment amount from $390.0 million to $437.5 million, (b) increase the uncommitted maximum facility amount from $400.0 million to $437.5 million, (c) modify the advance rates for solar energy systems and (d) modify the interest rates to an adjusted LIBOR rate plus a weighted average margin of 4.15%. In October 2020, we amended the TEPH revolving credit facility to, among other things, increase the aggregate commitment amount from $437.5 million to $460.7 million and increase the uncommitted maximum facility amount from $437.5 million to $600.0 million. In November 2020, we amended the TEPH revolving credit facility to, among other things, (a) reduce the borrowing base applied to certain solar assets and (b) include a carve-out for certain solar assets in the determination of the projected hedged SREC ratio. In November 2020, proceeds from the SOLII Notes (as defined below) were used to repay $211.5 million in aggregate principal amount outstanding of TEPH debt. In January 2021, we amended the TEPH revolving credit facility to, among other things, (a) permit certain transactions in SRECs (or proceeds therefrom) and related hedging arrangements and exclude certain of such amounts from the calculation of net cash flow available to service the indebtedness and (b) allow for borrowings with respect to certain ancillary components. In June 2021, proceeds from the SOLIII Notes (as defined below) were used to repay $105.1 million in aggregate principal amount outstanding of TEPH debt. In September 2021, we amended the TEPH revolving credit facility to, among other things, modify the hedging requirements to be based on borrowing capacity until March 2022, rather than amount currently borrowed.

*HELIX Debt.*&nbsp;&nbsp;&nbsp;&nbsp;In August 2022, we pooled and transferred eligible solar loans and the related receivables into HELIX, a special purpose entity, that issued $178.0 million in aggregate principal amount of Series 2022-B Class A solar loan-backed notes and $49.7 million in aggregate principal amount of Series 2022-B Class B solar loan-backed notes (collectively, the "HELIX Notes") with a maturity date of August 2049. The HELIX Notes were issued at a discount of 0.69% for Class A and 5.10% for Class B and bear interest at an annual rate of 5.00% and 6.00%, respectively. The cash flows generated by these solar loans are used to service the monthly principal and interest payments on the HELIX Notes and satisfy HELIX's expenses, and any remaining cash can be distributed to Sunnova Helios IX Depositor, LLC, HELIX's sole member. In connection with the HELIX Notes, certain of our affiliates receive a fee for managing and servicing the solar energy systems pursuant to management and service agreements. In addition, Sunnova Energy Corporation has guaranteed, among other things, (a) the obligations of certain of our subsidiaries to manage and service the solar energy systems pursuant to management and servicing agreements and (b) certain of our subsidiaries' obligations to repurchase or substitute certain ineligible solar loans eventually sold to HELIX pursuant to the related sale and contribution agreement. HELIX is also required to maintain certain reserve accounts for the benefit of the holders of the HELIX Notes, each of which must be funded at all times to the levels specified in the HELIX Notes. The holders of the HELIX Notes have no recourse to our other assets except as expressly set forth in the HELIX Notes.

*HELX Debt.*&nbsp;&nbsp;&nbsp;&nbsp;In November 2022, we pooled and transferred eligible solar loans and the related receivables into HELX, a special purpose entity, that issued $103.4 million in aggregate principal amount of Series 2022-C Class A solar loan-backed notes, $80.6 million in aggregate principal amount of Series 2022-C Class B solar loan-backed notes and $51.7 million in aggregate principal amount of Series 2022-C Class C solar loan-backed notes (collectively, the "HELX Notes") with a maturity date of November 2049. The Class C notes have been retained by one of our subsidiaries since their issuance. The HELX Notes

The cash flows generated by these solar loans are used to service the monthly principal and interest payments on the HELX Notes and satisfy HELX's expenses, and any remaining cash can be distributed to Sunnova Helios X Depositor, LLC, HELX's sole member. In connection with the HELX Notes, certain of our affiliates receive a fee for managing and servicing the solar energy systems pursuant to management and service agreements. In addition, Sunnova Energy Corporation has guaranteed, among other things, (a) the obligations of certain of our subsidiaries to manage and service the solar energy systems pursuant to management and servicing agreements and (b) certain of our subsidiaries' obligations to repurchase or substitute certain ineligible solar loans eventually sold to HELX pursuant to the related sale and contribution agreement. HELX is also required to maintain certain reserve accounts for the benefit of the holders of the HELX Notes, each of which must be funded at all times to the levels specified in the HELX Notes.

**(10) Derivative Instruments**

*Interest Rate Swaps and Caps on EZOP Debt.*&nbsp;&nbsp;&nbsp;&nbsp;During the years ended December 31, 2022 and 2021, EZOP entered into interest rate swaps and caps for an aggregate notional amount of $506.6 million and $360.2 million, respectively, to economically hedge its exposure to the variable interest rates on a portion of the outstanding EZOP debt. No collateral was posted for the interest rate swaps and caps as they are secured under the EZOP revolving credit facility. In July 2022, the notional amount of the interest rate swaps and caps began decreasing to match EZOP's estimated monthly principal payments on the debt. During the years ended December 31, 2022 and 2021, EZOP unwound interest rate swaps and caps with an aggregate notional amount of $360.2 million and $131.7 million, respectively, and recorded a realized gain of $22.9 million and a realized loss of $68,000, respectively.

*Interest Rate Swaps and Caps on TEPH Debt.*&nbsp;&nbsp;&nbsp;&nbsp;During the years ended December 31, 2022 and 2021, TEPH entered into interest rate swaps and caps for an aggregate notional amount of $524.9 million and $236.3 million, respectively, to economically hedge its exposure to the variable interest rates on a portion of the outstanding TEPH debt. No collateral was posted for the interest rate swaps and caps as they are secured under the TEPH revolving credit facility. In October 2023, the notional amount of the interest rate swaps and caps will begin decreasing to match TEPH's estimated quarterly principal payments on the debt. During the years ended December 31, 2022 and 2021, TEPH unwound interest rate swaps and caps with an aggregate notional amount of $515.4 million and $121.3 million, respectively, and recorded a realized gain of $28.3 million and a realized loss of $2.2 million, respectively.

*Interest Rate Swaps and Caps on AP8 Debt.*&nbsp;&nbsp;&nbsp;&nbsp;During the years ended December 31, 2022 and 2021, AP8 entered into interest rate swaps and caps for an aggregate notional amount of $75.0 million and $0, respectively, to economically hedge its exposure to the variable interest rates on a portion of the outstanding AP8 debt. No collateral was posted for the interest rate swaps and caps as they are secured under the AP8 revolving credit facility. The notional amount of the interest rate swaps and caps is locked for the life of the contract.

A full valuation allowance of $252.1 million and $281.6 million was recorded against our net deferred tax assets as of December 31, 2022 and 2021, respectively. We believe it is not more likely than not that future taxable income and the reversal of deferred tax liabilities will be sufficient to realize our net deferred tax assets. Our estimated federal tax net operating loss carryforward as of December 31, 2022 is approximately $1.2 billion, which will begin to expire in 2032 if not utilized. We also generated $9.8 million of Section 48(a) ITCs in 2022 for a net $285.6 million through December 31, 2022, which will begin to expire in 2033 if not utilized.

We assessed whether we had any significant uncertain tax positions taken in a filed tax return, planned to be taken in a future tax return or claim, or otherwise subject to interpretation and determined there were none not more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position, or prospectively approved when such approval may be sought in advance. Accordingly, we recorded no reserve for uncertain tax positions. Should a provision for any interest or penalties relative to unrecognized tax benefits be necessary, it is our policy to accrue for such in our income tax accounts. There were no such accruals as of December 31, 2022 and 2021 and we do not expect a significant change in gross unrecognized tax benefits in the next twelve months. Our tax years after 2011 remain subject to examination by the IRS and by the taxing authorities in the states and territories in which we operate.

Under the provisions of the Internal Revenue Code and similar state provisions, our net operating loss carryforwards and tax credit carryforwards are subject to review and possible adjustment by the IRS and state tax authorities. Under Sections 382 and 383 of the Internal Revenue Code, as well as similar state provisions, our net operating loss and tax credit carryforwards may be subject to an annual limitation in the event of certain cumulative changes in the ownership interest of certain significant shareholders over a three-year period in excess of 50%. This could limit the amount of tax attributes that can be utilized annually to offset future taxable income or tax liabilities. The amount of the annual limitation is determined based on the value of our company immediately prior to the ownership change. Subsequent ownership changes may further affect the limitation in future years. We experienced an ownership change in August 2020 as defined by Sections 382 and 383 of the Internal Revenue Code, which limits our future ability to utilize NOLs and tax credits generated before the "ownership change". However, these limitations do not prevent the use of our NOLs to offset certain built-in gains, including deemed gains with respect to our cost recovery deductions, recognized by us within five years after the ownership change with respect to assets held by us at the time of the ownership change, or the use of our tax credits to offset related tax liabilities, to the extent of our "net unrealized built-in gain" at the time of the ownership change. We have determined that, based upon the size of our net unrealized built-in gain at the time of our 2020 ownership change and our projected recognition of deemed built-in gains in the five years following the ownership change, there is no impact on the balances for deferred taxes or valuation allowance.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

We conduct operations in the U.S. territories of Puerto Rico, Guam and the Commonwealth of the Northern Mariana Islands. As a result, our income tax expense includes the effects of taxes incurred in such jurisdictions where the tax code for the respective jurisdiction may have separate tax-reporting requirements.

In March 2020, the U.S. enacted the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act"), featuring significant tax provisions and relief measures to assist individuals and businesses impacted by the economic effects of the COVID-19 pandemic. Relief measures intended to aid businesses in employee retention include payroll tax relief and a refundable tax credit for employers who retain employees during the COVID-19 pandemic. In addition, among other things, the CARES Act establishes (a) a five-year carryback of net operating losses generated in 2018, 2019 and 2020, (b) a temporary suspension of the 80% limitation on the use of net operating losses in 2018, 2019 and 2020 and (c) an increase to the adjusted taxable income limitation from 30% to 50% for business interest deductions under Section 163(j) of the U.S. Internal Revenue Code of 1986, as amended, for 2019 and 2020. We have historically maintained, and continue to maintain, a full valuation allowance against deferred tax assets. Due to our aggregate amount of net operating losses, we cannot utilize the carryback or limitation suspension provisions pertaining to the usage of net operating losses.

In December 2020, the U.S. enacted the Continued Assistance for Unemployment Workers Act of 2020 ("CARES Act II"), which provided an extension of the CARES Act's unemployment benefits. It also extended unemployment benefits to independent contractors and provided independent contractors with paid sick and family leave benefits through March 2021. In March 2021, the U.S. enacted the American Rescue Plant Act of 2021 ("ARP Act"), which further extended certain unemployment benefits through early September 2021. The CARES Act, the CARES Act II and the ARP Act have no impact on our valuation allowance.

In August 2022, the Inflation Reduction Act of 2022 (the "IRA") was signed into law. Among other things, the IRA expanded and extended the tax credits available to solar energy projects in an effort to achieve President Biden's non-binding target of net-zero emissions by 2050. The IRA extends the investment tax credit for eligible solar energy projects through at least 2033 and, depending on the location of a particular project, its size, its ability to satisfy certain labor and domestic content requirements and the category of consumers it serves, the investment tax credit percentage can range between 6% and 70%.

**(12) Acquisitions**

In February 2021, we entered into an Agreement and Plan of Merger (the "Merger Agreement") with certain of our subsidiaries, SunStreet and LEN X, LLC, a Florida limited liability company, the sole member of SunStreet and a wholly-owned subsidiary of Lennar Corporation ("Len<sup>x</sup>"). Pursuant to the Merger Agreement, in April 2021, we acquired SunStreet, Lennar Corporation's ("Lennar") residential solar platform, in exchange for up to 7,011,751 shares of our common stock (the "Acquisition"), comprised of 3,095,329 shares in initial consideration issued at closing, 27,526 shares related to the purchase price adjustments in the third quarter of 2021 and up to 3,888,896 shares issuable as earnout consideration after closing of the Acquisition as described below. We believe the Acquisition provides a new strategic path to further scale our solar business, reduces customer acquisition costs, provides a multi-year supply of sites through the development of new solar communities and allows us to pursue the development of clean and resilient microgrids across the U.S.

The purchase consideration was approximately $218.6 million, consisting of $128.2 million in the issuance of common stock shares and $90.4 million representing the fair value of contingent consideration based upon estimated new solar energy system installations through 2025 and the execution of certain binding agreements before the fifth anniversary of the closing of the Acquisition. Pursuant to the Earnout Agreement entered into between us and Len<sup>x</sup>, Len<sup>x</sup> will have the ability to earn up to an additional 3,888,896 shares of common stock over a five-year period in connection with the Acquisition. The earnout payments are conditioned on SunStreet meeting certain commercial milestones and achieving specified in-service levels. There are two elements to the earnout arrangement. First, we will issue up to 2,777,784 shares to the extent we and our subsidiaries (including SunStreet) place target amounts of solar energy systems into service and enter into qualifying customer agreements related to such solar energy systems. The 2,777,784 shares of common stock issuable under this portion of the earnout can be earned in four installments on a yearly basis (if the in-service target for each such year is achieved) or at the end of the four-year period (if the cumulative in-service target is achieved by the fourth and final year), with the annual periods commencing on the closing date of the Acquisition. See Note 14, Stockholders' Equity. This earnout is recorded as contingent consideration. The second element of the earnout is related to the development of microgrid communities. Pursuant to this portion of the earnout, we will issue up to 1,111,112 shares in two separate tranches, each of which has different criteria, if, prior to the fifth anniversary of the closing date of the Acquisition, we enter into binding agreements for the development of microgrid communities. One of these tranches is recorded as contingent consideration. As of December 31, 2022, the amount of contingent consideration that could be paid to Lennar has an estimated maximum value of $50.8 million and a minimum value of $9.8 million. These values were determined based on the projected average share price over the five year earnout period

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

multiplied by the number of shares to be transferred to Lennar if the targets for purchased solar energy systems placed in service are achieved. In connection with the Acquisition, Lennar has committed to contribute an aggregate $200.0 million (the "Funding Commitment") to four Sunnova tax equity funds, each formed annually during a period of four consecutive years (each such year, a "Contribution Year") commencing in 2021. See Note 13, Redeemable Noncontrolling Interests and Noncontrolling Interests. The solar service agreements and related solar energy systems acquired by each of these four tax equity funds will generally be originated by SunStreet, though a certain number of solar service agreements may be originated by our dealers, subject to certain criteria and expected in-service levels for the year. The favorable terms of the Funding Commitment result in an intangible asset. During the years ended December 31, 2022 and 2021, we incurred transaction costs of $7.8 million and $6.7 million related to acquisitions.

The fair values of the assets acquired and liabilities assumed are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. We estimated the fair value of the assets acquired at the acquisition date using a multi-period excess earnings methodology for customer relationships related to system sales and servicing, a cost savings methodology for customer relationships related to new customers, a relief from royalty methodology for the trade name and a discounted cash flow methodology for the tax equity commitment, all using Level 3 inputs.

During the third quarter of 2021, we made changes to our purchase price allocation for facts and circumstances that existed at the acquisition date related to (a) the issuance of additional shares of common stock, (b) changes to the aggregate principal amount of the debt acquired, (c) modifications to the forecasted cash flows for the intangible assets, (d) modifications to the estimated earnout consideration and (e) resulting changes to goodwill. During the third quarter of 2021, we recorded an increase to goodwill of $9.1 million as a result of purchase price adjustments. The following table presents the fair value of the assets acquired and liabilities assumed, inclusive of the purchase price adjustments, with the excess recorded as goodwill:

---

| | |
|:---|:---|
| | **As<br>Adjusted** |
| | **(in thousands)** |
| Cash | $503 |
| Other current assets (includes inventory of $26,835) | 33562 |
| Property and equipment | 217 |
| Intangible assets | 211836 |
| Other assets | 1060 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total assets acquired | 247178 |
| Accounts payable | 3762 |
| Accrued expenses | 4580 |
| Current portion of long-term debt | 32301 |
| Other current liabilities | 364 |
| Other long-term liabilities | 697 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total liabilities assumed | 41704 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Net assets acquired, excluding goodwill | 205474 |
| Purchase consideration | 218624 |
| &nbsp;&nbsp;&nbsp;&nbsp;Goodwill | $13150 |

---

Goodwill represents the excess of the purchase consideration over the aggregate fair value of the assets acquired and liabilities assumed. Goodwill is primarily attributable to the acquired assembled workforce. We do not expect to take any tax deductions for the goodwill associated with the Acquisition unless we decide to make an asset election in the future that would make a portion of the goodwill deductible for tax purposes. The portion of revenue and earnings associated with the acquired business was not separately identifiable due to the integration with our operations.

The purpose of the tax equity entities is to own and operate a portfolio of solar energy systems and energy storage systems. The terms of the tax equity entities' operating agreements contain allocations of taxable income (loss), Section 48(a) ITCs and cash distributions that vary over time and adjust between the members on an agreed date (referred to as the flip date). The operating agreements specify either a date certain flip date or an internal rate of return ("IRR") flip date. The date certain flip date is based on the passage of a fixed period of time that generally corresponds to the expiration of the recapture period associated with Section 48(a) ITCs or a year thereafter. The IRR flip date is the date on which the tax equity investor has achieved a contractual rate of return. From inception through the flip date, the Class A members' allocation of taxable income (loss) and Section 48(a) ITCs is generally 99% and the Class B members' allocation of taxable income (loss) and Section 48(a) ITCs is generally 1%. TEPIVA, TEPIVB, TEPIVC, TEPIVD, TEPIVE, TEPIVG, TEPVB, TEPVC, TEPVD, TEP6A, TEP6B, TEP6C, TEP6D, TEP7A and TEP7D also have a step-down period prior to the flip date during which the Class A members' allocation of certain items within taxable income (loss) become 67% and the Class B members' allocation of certain items within taxable income (loss) become 33% and TEPIVG, TEPVB, TEPVC and TEP6B also have an additional step-down period prior to the flip date during which the Class A members' allocation of certain items within taxable income (loss) are further reduced and the Class B members' allocation of certain items within taxable income (loss) are further increased. After the related flip date (or, if the tax equity investor has a deficit capital account, typically after such deficit has been eliminated), the Class A members' allocation of taxable income (loss) will typically decrease to 5% (or, in some cases, a higher percentage if required by the tax equity investor) and the Class B members' allocation of taxable income (loss) will increase by an inverse amount.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

The redeemable noncontrolling interests and noncontrolling interests are comprised of Class A units, which represent the tax equity investors' interest in the tax equity entities. Both the Class A members and Class B members have call options to allow either member to redeem the other member's interest in the tax equity entities upon the occurrence of certain contingent events, such as bankruptcy, dissolution/liquidation and forced divestitures of the tax equity entities. Additionally, except for TEPIVG, TEPVB and TEP6B, the Class B members have the option to purchase all Class A units, which is typically exercisable at any time during the periods specified under each respective governing document, and, in regard to the tax equity entities classified as redeemable noncontrolling interests, also have the contingent obligation to purchase all Class A units if the Class A members exercise their right to withdraw, which is typically exercisable at any time during the periods specified under each respective governing document. The carrying values of the redeemable noncontrolling interests were equal to or greater than the estimated redemption values as of December 31, 2022 and 2021.

*Guarantees*.&nbsp;&nbsp;&nbsp;&nbsp;We are contractually obligated to make certain Class A members whole for losses they may suffer in certain limited circumstances resulting from the disallowance or recapture of Section 48(a) ITCs. We have concluded the likelihood of a significant recapture event is remote and consequently have not recorded a liability for any potential recapture exposure. The maximum potential future payments we could be required to make under this obligation would depend on the IRS successfully asserting upon audit the fair market values of the solar energy systems sold or transferred to the tax equity entities as determined by us exceed the allowable basis for the systems for purposes of claiming Section 48(a) ITCs. The fair market values of the solar energy systems and related Section 48(a) ITCs are determined, and the Section 48(a) ITCs are allocated to the Class A members, in accordance with the tax equity entities' operating agreements. Due to uncertainties associated with estimating the timing and amounts of distributions, the likelihood of an event that may trigger repayment, forfeiture or recapture of Section 48(a) ITCs to such Class A members, and the fact that we cannot determine how the IRS will evaluate system values used in claiming Section 48(a) ITCs, we cannot determine the potential maximum future payments that are required under these guarantees.

From time to time, we incur non-performance fees, which may include, but is not limited to, delays in the installation process and interconnection to the power grid of solar energy systems and other factors. The non-performance fees are settled by either a return of a portion of the Class A members' capital contributions or an additional payment to the Class A members. During the years ended December 31, 2022, 2021 and 2020, we paid $9.5 million, $41.2 million and $2.1 million, respectively, related to non-performance fees. As of December 31, 2022 and 2021, we recorded a liability of $170,000 and $5.1 million, respectively, related to non-performance fees.

**(14) Stockholders' Equity**

In December 2020, we sold 4,025,000 shares of common stock at a public offering price of $37.00 per share. We received aggregate net proceeds of approximately $142.7 million, after deducting underwriting discounts and commissions of approximately $6.0 million and offering expenses of approximately $300,000. We used the net proceeds from the offering to acquire solar equipment, repay indebtedness and for working capital purposes.

During the year ended December 31, 2020, certain of the holders of our 9.75% convertible senior notes converted approximately $150.8 million aggregate principal amount, including accrued and unpaid interest to the date of each conversion, of our 9.75% convertible senior notes into 11,168,874 shares of our common stock. Such conversions resulted in a loss on extinguishment of debt under GAAP of $142.8 million for the year ended December 31, 2020.

During the year ended December 31, 2021, the remaining holders of our 9.75% convertible senior notes converted approximately $97.1 million aggregate principal amount, including accrued and unpaid interest to the date of each conversion, of our 9.75% convertible senior notes into 7,196,035 shares of our common stock. In April 2021, we issued 3,095,329 shares of common stock in connection with the Acquisition. In August 2021, we issued an additional 27,526 shares of common stock in connection with the purchase price adjustments of the Acquisition. See Note 12, Acquisitions. In November 2021, we issued 1,027,409 shares of common stock in connection with our investments in solar receivables. See Note 8, Investments in Solar Receivables.

During the year ended December 31, 2022, we issued 694,446 shares of our common stock to Len<sup>x</sup>, LLC pursuant to the terms of the earnout agreement entered into in connection with the SunStreet acquisition. See Note 12, Acquisitions.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**(15) Equity-Based Compensation**

Effective December 2013 and January 2015, we established and adopted two stock option plans (collectively, the "Prior Plans") after approval by our Board. The Prior Plans provided the aggregate number of shares of common stock that may be issued pursuant to stock options shall not exceed 26,032 shares. No further awards may be made under the Prior Plans.

Effective March 2016, we established and adopted a new stock option plan (the "2016 Plan") after approval by our Board. The 2016 Plan allowed for the issuance of non-qualified and incentive stock options. The 2016 Plan provided the aggregate number of shares of common stock that may be issued pursuant to stock options shall not exceed 4,288,950 shares. No further awards may be made under the 2016 Plan.

In connection with our IPO, our Board adopted the 2019 Long-Term Incentive Plan (the "LTIP") to incentivize employees, officers, directors and other service providers of SEI and its affiliates. The LTIP provides for the grant, from time to time, at the discretion of our Board or a committee thereof, of stock options, stock appreciation rights, stock awards, including restricted stock and restricted stock units, performance awards and cash awards. The LTIP provides the aggregate number of shares of common stock that may be issued pursuant to awards shall not exceed 5,229,318 shares. The number of shares available for issuance under the LTIP will be increased each fiscal year beginning in 2020, in an amount equal to the lesser of (a) a number of shares such that the total number of shares that remain available for additional grants under the LTIP equals five percent of the outstanding shares of our common stock on the last day of the immediately preceding fiscal year or (b) such number of shares determined by our Board. In February 2022, the aggregate number of shares of common stock that may be issued pursuant to awards under the LTIP was increased by 1,265,071, an amount which, together with the shares remaining available for grant under the LTIP, is equal to 5,667,761, or 5% of the number of shares of common stock outstanding as of December 31, 2021. Awards granted under the LTIP contain a service condition and cease vesting for employees, consultants and directors upon termination of employment or service. The grant date fair value of awards granted under the LTIP will be recognized ratably over the applicable vesting period of each award (either one year, three years or seven years).

The Prior Plans and the 2016 Plan will only allow for settlement of stock options by the issuance of common stock and awards issued under the LTIP can generally only be settled by the issuance of common stock. Therefore, we classify the awards as equity awards. We recognize the fair value of equity-based compensation awards as compensation cost in the financial statements, beginning on the grant date. We base compensation expense on the fair value of the awards we expect to vest, recognized over the service period, and adjusted for actual forfeitures that occur before vesting.

***Stock Options***

During 2020, no stock options were granted and 922,770 stock options were exercised resulting in the issuance of 922,770 shares of common stock in exchange for $13.6 million. During 2021, 75,031 stock options were granted and 569,740 stock options were exercised resulting in the issuance of 569,740 shares of common stock in exchange for $9.0 million. During 2022, 538,758 stock options were granted and 18,383 stock options were exercised resulting in the issuance of 18,383 shares of common stock in exchange for $213,000.

We used the following assumptions to apply the Black-Scholes option-pricing model to stock options granted during the years ended December 31, 2022 and 2021:

---

| | | |
|:---|:---|:---|
| | **Year Ended <br> December 31,** | **Year Ended <br> December 31,** |
| | **2022** | **2021** |
| Expected dividend yield | 0.00% | 0.00% |
| Risk-free interest rate | 2.40% | 1.13% |
| Expected term (in years) | 6.375 - 6.46 | 6.13 |
| Volatility | 59% | 55% |

---

The expected volatility was calculated based on the average historical volatilities of publicly traded peer companies determined by us. The risk-free interest rate used was based on the U.S. treasury yield curve in effect at the time of grant for the expected term of the stock options to be valued. The expected dividend yield is zero as we do not anticipate paying common

***Employee Stock Purchase Plan***

Effective May 2022, we established an Employee Stock Purchase Plan (the "ESPP"). We are authorized to issue up to an aggregate 750,000 shares of common stock under the ESPP. The ESPP allows eligible employees to purchase shares of our common stock at a price per share equal to 95% of the lesser of the closing price of our common stock on the grant date or the purchase date. Payment for shares of our common stock is made as of the purchase date through payroll deductions on an after-tax basis over the designated purchase period. Each purchase period will generally be a six-month period commencing on January 1 and July 1 of each year, or such other period as the plan administrator may prescribe. The applicable purchase date is the last trading day of the purchase period or other such trading date designated by the plan administrator. An employee's payroll deductions under the ESPP are limited to 15% of the employee's eligible compensation with an annual limitation of $25,000. As of December 31, 2022, 7,106 shares of common stock were issued under the ESPP.

**(17) Commitments and Contingencies**

*Legal.&nbsp;&nbsp;&nbsp;&nbsp;*We are a party to a number of lawsuits, claims and governmental proceedings which are ordinary, routine matters incidental to our business. In addition, in the ordinary course of business, we periodically have disputes with dealers and customers. We do not expect the outcomes of these matters to have, either individually or in the aggregate, a material adverse effect on our financial position or results of operations.

*Performance Guarantee Obligations.&nbsp;&nbsp;&nbsp;&nbsp;*As of December 31, 2022, we recorded $4.8 million related to our guarantee of certain specified minimum solar energy production output under our leases and loans, of which $2.5 million is recorded in other current liabilities and $2.3 million is recorded in other long-term liabilities in the consolidated balance sheet. As of December 31, 2021, we recorded $5.3 million related to these guarantees, of which $3.2 million is recorded in other current liabilities and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)Amounts are revised for the immaterial prior period revisions discussed below.

***Revisions***

We have revised our previously issued interim unaudited condensed consolidated financial statements ("interim financial statements") to correct immaterial errors pertaining to our interest rate derivative financial instruments, specifically the credit valuation adjustment to account for the counterparties' credit risk. We did not record the estimated reduction to the derivative assets related to the credit valuation adjustment as of March 31, 2022, June 30, 2022 and September 30, 2022. These immaterial errors impacted our consolidated balance sheets, consolidated statements of operations, consolidated statements of cash flows and consolidated statements of redeemable noncontrolling interests and equity. The impacted periods will be revised in future filings, as applicable. The following tables present the impact of these revisions on the interim financial statements:

**(1) Basis of Presentation**

On July 24, 2019, Sunnova Energy International Inc. ("SEI") priced 14,000,000 shares of its common stock at a public offering price of $12.00 per share and on July 25, 2019, SEI's common stock began trading on the New York Stock Exchange under the symbol "NOVA". Upon the closing of our initial public offering on July 29, 2019 (our "IPO"), Sunnova Energy Corporation was contributed to SEI and SEI became the holding company of Sunnova Energy Corporation through a reverse merger. In addition, the historical financial statements of Sunnova Energy Corporation became the historical financial statements of SEI. These condensed financial statements include the condensed balance sheets, condensed statements of operations and condensed statements of cash flows and have been prepared on a parent-only basis. These parent-only financial statements do not include all of the information and notes required by accounting principles generally accepted in the United States of America for annual financial statements and therefore, these parent-only financial statements and other information included should be read in conjunction with SEI's consolidated financial statements and related notes contained within this Annual Report on Form 10-K.

**Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure.**

None.

**Item 9A. Controls and Procedures.**

**Internal Control Over Financial Reporting**

*Evaluation of Disclosure Controls and Procedures*

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer ("CEO") and our Chief Financial Officer ("CFO"), of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Annual Report on Form 10-K, pursuant to Rules 13a-15(e) and 15d-15(e) under the Exchange Act. In connection with that evaluation, our CEO and our CFO concluded our disclosure controls and procedures were effective and designed to provide reasonable assurance the information required to be disclosed is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms as of December 31, 2022, and that such information is accumulated and communicated to our management, including our CEO and CFO, as appropriate to allow timely decisions regarding required disclosures. The term "disclosure controls and procedures", as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure information required to be disclosed by a company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure information required to be disclosed by a company in the reports it files or submits under the Exchange Act is accumulated and communicated to the company's management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Management recognizes any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

*Changes in Internal Control over Financial Reporting*

We completed the acquisition of SunStreet in April 2021. We excluded SunStreet's internal control over financial reporting from the scope of management's 2021 annual assessment of the effectiveness of our internal control over financial reporting as we made efforts to integrate SunStreet's accounts, processes and internal controls over financial reporting into our financial reporting framework. Such changes in our internal control over financial reporting (as described in Rule 13a-15(f) and 15d-15(f) under the Exchange Act), which have been substantially completed, have not materially affected our internal control over financial reporting. Other than the changes that resulted from such integration, there was no change in our internal control over financial reporting that occurred during the fourth quarter of 2022 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

*Limitations on Effectiveness of Controls and Procedures*

Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives as specified above. However, our management, including our principal executive and principal financial officers, does not expect that our disclosure controls and procedures will prevent or detect all error and fraud. Any control system, no matter how well designed and operated, is based upon certain assumptions and can provide only reasonable, not absolute, assurance that its objectives will be met. Further, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within our company have been detected.

*Management's Report on Internal Control over Financial Reporting*

Management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined by Rule 13a-15(f) under the Exchange Act). Management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission to evaluate the effectiveness of our internal control over financial reporting. Management has assessed the effectiveness of our internal control over financial reporting as of December 31, 2022 and has concluded that such internal control over financial reporting is effective.

The effectiveness of our internal control over financial reporting as of December 31, 2022 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in its report which is included in Item 8 of this Annual Report on Form 10-K.

This Indenture (as amended or supplemented from time to time, this "*Indenture*") is dated as of November 10, 2022 between Sunnova Helios X Issuer, LLC, a limited liability company organized under the laws of the State of Delaware, as issuer (the "*Issuer*"), and Wilmington Trust, National Association, a national banking association, not in its individual capacity but solely in its capacity as indenture trustee (together with its successors and assigns in such capacity, the "*Indenture Trustee*").

**Preliminary Statement**

Pursuant to this Indenture, there is hereby duly authorized the execution and delivery of three classes of notes designated as the Issuer's 5.30% Solar Loan Backed Notes, Series 2022-C, Class A (the "*Class A Notes*"), Issuer's 5.60% Solar Loan Backed Notes, Series 2022-C, Class B (the "*Class B Notes*") and the Issuer's 6.00% Solar Loan Backed Notes, Series 2022-C, Class C (the "*Class C Notes*" and together with the Class A Notes and the Class B Notes, the "*Notes*"). All covenants and agreements made by the Issuer herein are for the benefit and security of the Holders of the Notes. The Issuer is entering into this Indenture, and the Indenture Trustee is accepting the trusts created hereby, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged.

**Granting Clause**

The Issuer hereby Grants to the Indenture Trustee, for the benefit of the Holders of the Notes, as their interests may appear, all of the rights, title, interest and benefits of the Issuer whether now existing or hereafter arising in and to (i) the Initial Solar Loans and any Qualified Substitute Solar Loans, (ii) all Solar Loan Files related to the Solar Loans and any property or assets of the Obligors pledged as collateral under a Solar Loan to secure the repayment of such Solar Loan, including without limitation the related PV System and/or Energy Storage System, each now and hereafter owned, (iii) each Solar Loan Agreement including the right to (a) receive all amounts due under or required to be paid pursuant to such Solar Loan Agreement on and after the related Cut-Off Date (including all interest capitalized and added to the Solar Loan Balance of a Solar Loan on a Section 25D Credit Payment Date, if any), (b) all security interests, liens and assignments securing payment of such Solar Loan Agreement and (c) all books, records and computer tapes relating to such Solar Loan Agreement; (iv) the Issuer's rights in the Electronic Vault, (v) all rights and remedies under the Contribution Agreement, the Performance Guaranty, the Management Agreement, the Servicing Agreement, the Custodial Agreement, any Letter of Credit and all other Transaction Documents, (vi) amounts (including all amounts collected from each Obligor under its Solar Loan Agreement) deposited from time to time into the Lockbox Account, the Collection Account, the Reserve Account, the Equipment Replacement Reserve Account, the Section 25D Interest Account and all amounts deposited from time to time and all Eligible Investments in each such account, (vii) all other assets of the Issuer, and (viii) the proceeds of any and all of the foregoing including all proceeds of the conversion, voluntary or involuntary, of any of the foregoing into cash or other property (collectively, the "*Trust Estate*"). Notwithstanding the foregoing, the Trust Estate shall not include (i) any returned items required to be returned to the financial institution maintaining the Lockbox Account, (ii) Obligor Security Deposits on deposit in the Obligor Security Deposit Account nor (iii) amounts received relating to Grid Services.

Such Grant is made in trust, to secure payments of amounts due with respect to the Notes ratably and without prejudice, priority or distinction between or among the Notes, and to secure (i) the payment of all amounts on the Notes as such amounts become due in accordance with their terms; (ii) the payment of all other sums payable in accordance with the provisions of this

&nbsp;&nbsp;&nbsp;&nbsp;[\*\*\*] = Certain information has been excluded from this exhibit because it is both not material and would likely cause harm to the company if publicly disclosed.

------

Indenture; and (iii) compliance with the provisions of this Indenture, all as provided in this Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)Holders of the Notes shall be entitled to payments of interest and principal as provided herein. Each Class of Notes shall have a final maturity on the Rated Final Maturity. All Notes of the same Class shall be secured on parity with one another, with no Note of any Class having any priority over any other Note of that same Class.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)The Notes that are authenticated and delivered to the Noteholders by the Indenture Trustee upon an Issuer Order on the Closing Date shall be dated as of the Closing Date. Any Note issued later in exchange for, or in replacement of, any Note issued on the Closing Date shall be dated the date of its authentication.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g)Each Class of Notes is issuable in minimum denominations of $100,000 and integral multiples of $1,000 in excess thereof; provided that one Note of each Class of Notes may be issued in an amount equal to the minimum initial denomination for such Class of Notes plus any remaining portion of the Initial Outstanding Note Balance of such Class of Notes; provided, further, that the foregoing shall not restrict or prevent the transfer in accordance with the last sentence of Section 2.07 hereof of any Note with a remaining Outstanding Note Balance of less than $100,000.

*Section 2.02.&nbsp;&nbsp;&nbsp;&nbsp;Forms of Notes*. The Notes shall be in substantially the form set forth in <u>Exhibit A-1</u>, <u>Exhibit A-2</u> and <u>Exhibit A-3</u>, as applicable, with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by this Indenture, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may, consistently herewith, be determined by the Issuer, as evidenced by its execution thereof.

The Definitive Notes shall be typewritten, printed, lithographed or engraved or produced by any combination of these methods, all as determined by the officers executing such Notes, as evidenced by their execution of such Notes.

Each Note shall be dated the date of its authentication. The terms of the Notes are set forth in <u>Exhibit A-1</u>, <u>Exhibit A-2</u> and <u>Exhibit A-3</u> are part of the terms of this Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)*Global Notes*. The Notes (other than the Class C Notes) are being offered and sold by the Issuer to the Initial Purchaser pursuant to the Note Purchase Agreement.

Notes offered and sold within the United States to QIBs in reliance on Rule 144A and, with respect to any Class C Notes acquired by Sunnova Energy or one of its Affiliates, Institutional Accredited Investors, shall be issued initially in the form of Rule 144A Global Notes, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Indenture Trustee, as custodian for the Securities Depository, and registered in the name of the Securities Depository or a nominee of the Securities Depository, duly executed by the Issuer and authenticated by the Indenture Trustee as hereinafter provided. The Outstanding Note Balance of the Rule 144A Global Notes may from time to time be increased or decreased by adjustments made on the records of the Indenture Trustee and the Securities Depository or its nominee as hereinafter provided. The Indenture Trustee shall not be liable for any error or omission by the Securities Depository in making such record adjustments and the records of the Indenture Trustee shall be controlling with regard to outstanding principal amount of Notes hereunder.

[\*\*\*] = Certain information has been excluded from this exhibit because it is both not material and would likely cause harm to the company if publicly disclosed.

------

Notes offered and sold outside of the United States in reliance on Regulation S under the Securities Act shall initially be issued in the form of a Regulation S Temporary Global Note, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Indenture Trustee, as custodian for the Securities Depository, and registered in the name of the Securities Depository or the nominee of the Securities Depository for the investors' respective accounts at Euroclear Bank S.A./N.V. as operator of the Euroclear System ("*Euroclear*") or Clearstream Banking *société anonyme* ("*Clearstream*"), duly executed by the Issuer and authenticated by the Indenture Trustee as hereinafter provided. Beneficial interests in the Regulation S Temporary Global Notes may be held only through Euroclear or Clearstream.

Within a reasonable period of time following the expiration of the "40-day distribution compliance period" (as defined in Regulation S), beneficial interests in the Regulation S Temporary Global Note shall be exchanged for beneficial interests in Regulation S Permanent Global Notes upon the receipt by the Indenture Trustee of (i) a written certificate from the Securities Depository, together with copies of certificates from Euroclear and Clearstream, certifying that they have received certification of non-United States beneficial ownership of 100% of the Outstanding Note Balance of the Regulation S Temporary Global Note (except to the extent of any beneficial owners thereof who acquired an interest therein pursuant to another exemption from registration under the Securities Act and who will take delivery of a beneficial ownership interest in a Rule 144A Global Note, all as contemplated by Section 2.08(a)(ii)), and (ii) an Officer's Certificate from the Issuer. The Regulation S Permanent Global Notes will be deposited with the Indenture Trustee, as custodian, and registered in the name of a nominee of the Securities Depository. Simultaneously with the authentication of the Regulation S Permanent Global Notes, the Indenture Trustee shall cancel the Regulation S Temporary Global Note. The Outstanding Note Balance of the Regulation S Temporary Global Note and the Regulation S Permanent Global Notes may from time to time be increased or decreased by adjustments made on the records of the Indenture Trustee and the Securities Depository or its nominee, as the case may be, in connection with transfers of interest as hereinafter provided. The Indenture Trustee shall incur no liability for any error or omission of the Securities Depository in making such record adjustments and the records of the Indenture Trustee shall be controlling with regard to outstanding principal amount of Regulation S Global Notes hereunder.

Each Global Note shall represent such of the outstanding Notes as shall be specified therein and each shall provide that it shall represent the aggregate amount of outstanding Notes from time to time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and prepayments. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Indenture Trustee, or by the Note Registrar at the direction of the Indenture Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.08.

The provisions of the "Operating Procedures of the Euroclear System" and "Terms and Conditions Governing Use of Euroclear" and the "Management Regulations" and "Instructions to Participants" of Clearstream shall be applicable to interests in the Regulation S Temporary Global Note and the Regulation S Permanent Global Notes that are held by the members of, or participants in, the Securities Depository ("*Agent Members*") through Euroclear or Clearstream.

Except as set forth in Section 2.08, the Global Notes may be transferred, in whole and not in part, only to another nominee of the Securities Depository or to a successor of the Securities Depository or its nominee.

[\*\*\*] = Certain information has been excluded from this exhibit because it is both not material and would likely cause harm to the company if publicly disclosed.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)*Book-Entry Provisions.* This Section 2.02(b) shall apply only to the Global Notes deposited with or on behalf of the Securities Depository.

The Issuer shall execute and the Indenture Trustee shall, in accordance with this Section 2.02(b), authenticate and deliver one Global Note for each Class of Notes which (i) shall be registered in the name of the Securities Depository or the nominee of the Securities Depository and (ii) shall be delivered by the Indenture Trustee to the Securities Depository or pursuant to the Securities Depository's instructions or held by the Indenture Trustee as custodian for the Securities Depository.

Agent Members shall have no rights either under this Indenture with respect to any Global Note held on their behalf by the Securities Depository or by the Indenture Trustee as custodian for the Securities Depository or under such Global Note, and the Securities Depository may be treated by the Issuer, the Indenture Trustee and any agent of the Issuer or the Indenture Trustee as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Indenture Trustee or any agent of the Issuer or the Indenture Trustee from giving effect to any written certification, proxy or other authorization furnished by the Securities Depository or impair, as between the Securities Depository and its Agent Members, the operation of customary practices of such Securities Depository governing the exercise of the rights of an owner of a beneficial interest in any Global Note.

The Note Registrar and the Indenture Trustee shall be entitled to treat the Securities Depository for all purposes of this Indenture (including the payment of principal of and interest on the Notes and the giving of instructions or directions hereunder) as the sole Holder of the Notes, and shall have no obligation to the Note Owners.

The rights of Note Owners shall be exercised only through the Securities Depository and shall be limited to those established by law and agreements between such Note Owners and the Securities Depository and/or the Agent Members pursuant to the Note Depository Agreement. The initial Securities Depository will make book-entry transfers among the Agent Members and receive and transmit payments of principal of and interest on the Notes to such Agent Members with respect to such Global Notes.

Whenever this Indenture requires or permits actions to be taken based upon instructions or directions of Holders of Notes evidencing a specified percentage of the Outstanding amount of the Notes, the Securities Depository shall be deemed to represent such percentage only to the extent that it has received instructions to such effect from Note Owners and/or Agent Members owning or representing, respectively, such required percentage of the beneficial interest in the Notes and has delivered such instructions to the Indenture Trustee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)*Definitive Notes.* Except as provided in Sections 2.08 and 2.13, owners of beneficial interests in Global Notes will not be entitled to receive physical delivery of certificated definitive, fully registered Notes (the "*Definitive Notes*").

[\*\*\*] = Certain information has been excluded from this exhibit because it is both not material and would likely cause harm to the company if publicly disclosed.

------

*Section 2.03.&nbsp;&nbsp;&nbsp;&nbsp;Payment of Interest*. (a) Noteholders shall, subject to the priorities and conditions set forth in the Priority of Payments, be entitled to receive payments of interest and principal on each Payment Date. Any payment of interest or principal payable with respect to the Notes on the applicable Payment Date shall be made to the Person in whose name such Note is registered as of the Record Date for such Payment Date in the manner provided in Section 5.09.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)On each Payment Date, the Interest Distribution Amount for each Class of Notes will be distributed to the registered Noteholders of the applicable Class of Notes as of the related Record Date to the extent Available Funds are sufficient for such distribution in accordance with the Priority of Payments or the Acceleration Event Priority of Payments, as applicable. Interest on the Notes with respect to any Payment Date will accrue at the applicable Note Rate based on the Interest Accrual Period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)If the Aggregate Outstanding Note Balance has not been paid in full on or before the Anticipated Repayment Date, additional interest (the "*Post-ARD Additional Interest Amounts*") will begin to accrue during each Interest Accrual Period thereafter on each outstanding Class of Notes at the related Post-ARD Additional Interest Rate. The Post-ARD Additional Interest Amounts, if any, for a Class of Notes will only be due and payable (i) after the Aggregate Outstanding Note Balance, any Note Balance Write-Down Amounts and any Deferred Interest amounts have been paid in full or (ii) on the date on which a Voluntary Prepayment of all outstanding Notes in full is being made. Prior to such time, the Post-ARD Additional Interest Amounts accruing on a Class of Notes will be deferred and added to any Post-ARD Additional Interest Amounts previously deferred and remaining unpaid ("*Deferred Post-ARD Additional Interest Amounts*"). Deferred Post-ARD Additional Interest Amounts will not bear interest.

*Section 2.04.&nbsp;&nbsp;&nbsp;&nbsp;Payments to Noteholders*. (a) Principal payments and interest on a Class of Notes will be made on each Payment Date to the Noteholders of each Class as of the related Record Date pursuant to the Priority of Payments. The remaining Outstanding Note Balance of each Class of Notes, if any, shall be payable no later than the Rated Final Maturity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)All reductions in the principal balance of a Note (or one or more Predecessor Notes) effected by payments of principal made on any Payment Date shall be binding upon all Holders of such Note and of any Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof, whether or not such payment is noted on such Note.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)The Note Balance Write-Down Amount shall be applied in the following order of priority: (i) to the Class C Notes until the Outstanding Note Balance of the Class C Notes is reduced to zero, (ii) to the Class B Notes until the Outstanding Note Balance of the Class B Notes is reduced to zero and (iii) to the Class A Notes until the Outstanding Note Balance of the Class A Notes is reduced to zero. The application of the Note Balance Write-Down Amount to a Class of Notes will not reduce such Class' entitlement to unpaid principal and interest.

*Section 2.05.&nbsp;&nbsp;&nbsp;&nbsp;Execution, Authentication, Delivery and Dating*. (a) The Notes shall be executed by the Issuer. The signature of such Authorized Officer on the Notes may be manual or facsimile. Notes bearing the manual or facsimile signature of any individual who was, at the time of execution thereof, an Authorized Officer of the Issuer shall bind the Issuer, notwithstanding the fact that such individual ceased to hold such office prior to the authentication and delivery of such Notes or did not hold such office at the date of issuance of such Notes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)On the Closing Date, the Issuer shall, and at any time and from time to time after the execution and delivery of this Indenture, the Issuer may deliver Notes executed by the Issuer to the Indenture Trustee for authentication, and the Indenture Trustee, upon receipt of the Notes and of an Issuer Order, shall authenticate and deliver such Notes; *provided, however*, that the Indenture Trustee shall not authenticate the Notes on the Closing Date unless and until it shall have received the documents listed in Section 2.12.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Each Note authenticated and delivered by the Indenture Trustee to or upon an Issuer Order on or prior to the Closing Date shall be dated the Closing Date. All other Notes that are authenticated after the Closing Date for any other purpose under this Indenture shall be dated the date of their authentication.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Notes issued upon transfer, exchange or replacement of other Notes shall be issued in authorized denominations reflecting the Outstanding Note Balance so transferred, exchanged or replaced, but shall represent only the Outstanding Note Balance so transferred, exchanged or replaced. In the event that any Note is divided into more than one Note in accordance with this Article II, such Outstanding Note Balance shall be divided among the Notes delivered in exchange therefor.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Note a certificate of authentication, substantially in the form provided for herein, executed by the Indenture Trustee by the manual signature of a Responsible Officer of the Indenture Trustee, and such executed certificate upon

*Section 2.06.&nbsp;&nbsp;&nbsp;&nbsp;Temporary Notes*. Except for the Notes maintained in book-entry form, temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Definitive Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Issuer. Every such temporary Note shall be executed by the Issuer and authenticated by the Indenture Trustee upon the same conditions and in substantially the same manner, and with the same effect, as the Definitive Notes. Without unreasonable delay, the Issuer will execute and deliver to the Indenture Trustee Definitive Notes (other than in the case of Notes in global form) and thereupon any or all temporary Notes (other than in the case of Notes in global form) may be surrendered in exchange therefor, at the Corporate Trust Office, and the Indenture Trustee shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Definitive Notes. Such exchange shall be made by the Issuer at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Definitive Notes authenticated and delivered hereunder.

*Section 2.07.&nbsp;&nbsp;&nbsp;&nbsp;Registration, Registration of Transfer and Exchange*. (a) The Indenture Trustee (in such capacity, the "*Note Registrar*") shall cause to be kept at its Corporate Trust Office a register (the "*Note Register*"), in which, subject to such reasonable regulations as it may prescribe, the Note Registrar shall provide for the registration of the Notes and the registration of transfers of such Notes. The Notes are intended to be obligations in registered form for purposes of Section 163(f), Section 871(h)(2) and Section 881(c)(2) of the Code.

The purchaser is aware that it (or any account of a QIB for which it is purchasing) may be required to bear the economic risk of an investment in the Notes for an indefinite period, and it (or such account) is able to bear such risk for an indefinite period.

Notwithstanding the foregoing restriction, any Note that has originally been properly issued in an amount no less than the Minimum Denomination, or any interest therein, may be offered, resold, pledged or otherwise transferred in a denomination less than the Minimum Denomination if such lesser denomination is solely a result of a reduction of principal due to payments made in accordance with this Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h)If an Event of Default or Servicer Termination Event shall arise from the failure of the Servicer to perform any of its duties or obligations under the Servicing Agreement, the Issuer shall take all reasonable steps available to it to remedy such failure, including appointing a replacement Servicer pursuant to the terms of the Servicing Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)The Issuer, or the Servicer on behalf of the Issuer, will supply to the Indenture Trustee for further distribution to the Noteholders, at the time and in the manner required by

*Section 5.08.&nbsp;&nbsp;&nbsp;&nbsp;Equity Cure.* Sunnova Energy may, in its sole and absolute discretion, remit amounts to the Collection Account to cure an anticipated shortfall of any amounts required to be paid by the Borrower pursuant to the Priority of Payments; provided that (i) such deposits shall not exceed, cumulatively and in the aggregate for all Payment Dates, 15% of the aggregate Initial Outstanding Note Balance of the Notes and (ii) no more than one such remittance may be made in any twelve month period (each such payment by Sunnova Energy, a "**Permitted Equity Cure Payment**"). In the event that Sunnova Energy elects to make a Permitted Equity Cure Payment, Sunnova Energy shall notify the Issuer, the Indenture Trustee, the Backup Servicer and the Servicer of such election on or prior to the date that is not later than three Business Days prior to the related Determination Date.

*Section 5.09.&nbsp;&nbsp;&nbsp;&nbsp;Note Payments*. (a) The Indenture Trustee shall pay from amounts on deposit in the Collection Account in accordance with the Monthly Servicer Report and the Priority of Payments or the Acceleration Event Priority of Payments, as applicable, to each Noteholder of record as of the related Record Date either (i) by wire transfer, in immediately available funds to the account of such Noteholder at a bank or other entity having appropriate facilities therefor, if such Noteholder shall have provided to the Indenture Trustee appropriate written instructions at least five Business Days prior to the related Payment Date (which instructions may remain in effect for subsequent Payment Dates unless revoked by such Noteholder), or (ii) if not, by check mailed to such Noteholder at the address of such Noteholder appearing in the Note Register, the amounts to be paid to such Noteholder pursuant to such Noteholder's Notes; *provided, however*, that so long as the Notes are registered in the name of the Securities Depository such payments shall be made to the nominee thereof in immediately available funds.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)In the event that any withholding Tax is imposed on the Issuer's payment (or allocations of income) to a Noteholder, such withholding Tax shall reduce the amount otherwise distributable to the Noteholder in accordance with this Indenture. The Indenture Trustee is hereby authorized and directed to retain from amounts otherwise distributable to the Noteholders sufficient funds for the payment of any withholding Tax that is legally owed by the Issuer as instructed by the Servicer, in writing in a Monthly Servicer Report (but such authorization shall not prevent the Indenture Trustee from contesting at the expense of the applicable Noteholder any such withholding Tax in appropriate Proceedings, and withholding payment of such withholding Tax, if permitted by law, pending the outcome of such Proceedings). The amount of any withholding Tax imposed with respect to a Noteholder shall be treated as cash distributed to such Noteholder at the time it is withheld by the Issuer or the Indenture Trustee (at the direction of the Servicer or the Issuer) and remitted to the appropriate taxing authority. If there is a withholding Tax payable with respect to a distribution (such as a distribution to a non-U.S. Noteholder), the Indenture Trustee may in its sole discretion withhold such amounts in accordance with this clause (b). In the event that a Noteholder wishes to apply for a refund of any such withholding Tax, the Indenture Trustee shall reasonably cooperate with such Noteholder in making such claim so long as such Noteholder agrees to reimburse the Indenture Trustee for any out-of-pocket expenses incurred.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Each Noteholder and Note Owner, by its acceptance of a Note, will be deemed to have consented to the provisions of the Priority of Payments or the Acceleration Event Priority of Payments, as applicable.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)For all Tax purposes, each Noteholder and each Note Owner (other than to an Affiliate of Sunnova Energy that is disregarded as separate from Sunnova Energy for U.S. federal income tax purposes), by its acceptance of a Note, will be deemed to have agreed to, and hereby instructs the Indenture Trustee to, treat the Notes as indebtedness.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)Each Noteholder and each Note Owner by its acceptance of a Note or an interest in a Note, will be deemed to have agreed to provide the Indenture Trustee or the Issuer, upon request, with the Noteholder Tax Identification Information and, to the extent FATCA Withholding Tax is applicable, the Noteholder FATCA Information. Each Noteholder and Note Owner shall update or replace its previously provided Noteholder Tax Identification Information and Noteholder FATCA Information promptly if requested by the Indenture Trustee; *provided* that nothing herein shall require the Indenture Trustee to make such request. In addition, each Noteholder and each Note Owner will be deemed to agree that the Indenture Trustee has the right to withhold from any amount of interest or other amounts (without any corresponding gross-up) payable to a Noteholder or Note Owner that fails to comply with the foregoing requirements. The Issuer hereby covenants with the Indenture Trustee that the Issuer will cooperate with the Indenture Trustee in obtaining sufficient information so as to enable the Indenture Trustee to (i) determine whether or not the Indenture Trustee is obliged to make any withholding, including FATCA Withholding Tax, in respect of any payments with respect to a Note and (ii) to effectuate any such withholding. The parties agree that the Indenture Trustee shall be released of any liability arising from properly complying with this Section 5.09 and FATCA. The Issuer agrees to provide to the Indenture Trustee copies of any Noteholder Tax Identification Information and any Noteholder FATCA Information received by the Issuer from any Noteholder or Note Owner. Upon reasonable request from the Indenture Trustee, the Issuer will provide such additional information that it may have to assist the Indenture Trustee in making any withholdings or informational reports.

*Section 5.10.&nbsp;&nbsp;&nbsp;&nbsp;Statements to Noteholders; Tax Returns*. Within the time period required by Applicable Law after the end of each calendar year, the Issuer shall cause the Indenture Trustee to furnish to each Person who at any time during such calendar year was a Noteholder of record and received any payment thereon any information required by the Code to enable such Noteholders to prepare their U.S. federal and state income Tax Returns. The obligation of the Indenture Trustee set forth in this paragraph shall be deemed to have been satisfied to the extent that information shall be provided by the Indenture Trustee, in the form of Form 1099 or other comparable form, pursuant to any requirements of the Code.

The Issuer shall cause Sunnova Management, at Sunnova Management's expense, to cause a firm of Independent Accountants to prepare any Tax Returns required to be filed by the Issuer. The Indenture Trustee, upon reasonable written request, shall furnish the Issuer with all such information in the possession of the Indenture Trustee as may be reasonably required in connection with the preparation of any Tax Return of the Issuer.

Without limiting the generality of the foregoing, the Indenture Trustee shall, upon the written request of the Servicer, promptly transmit or make available electronically to the Servicer, copies of all accountings of, and information with respect to, the Collection Account, the Reserve Account, the Section 25D Interest Account and the Equipment Replacement Reserve Account, investments thereof, as applicable, and payments thereto and therefrom.

*Section 5.12.&nbsp;&nbsp;&nbsp;&nbsp;Final Balances.* On the Termination Date, all moneys remaining in all Accounts (other than the Lockbox Account), shall be, subject to applicable escheatment laws, remitted to, or at the direction of, the Issuer, and after the return of such funds (or disposition thereof pursuant to applicable escheatment laws), the Indenture Trustee will have no liability with respect to such funds, and holders should look solely only to the Issuer for such amounts.

**Article VI<br>Voluntary Prepayment of Notes and Release of Collateral**

*Section 6.01.&nbsp;&nbsp;&nbsp;&nbsp;Voluntary Prepayment.* (a) Prior to the Rated Final Maturity, the Issuer may, in its sole discretion, prepay the Notes, including by Class or portion of a Class (such prepayment, a "*Voluntary Prepayment*"), in whole or in part on any Business Day following the first anniversary of the Closing Date (such date, the "*Voluntary Prepayment Date*"). Any such Voluntary Prepayment is required to be made on no less than ten (10) days' prior notice (or such shorter period, but not less than two Business Days, as is necessary to cure an Event of Default) by the Issuer sending the Notice of Prepayment to the Indenture Trustee and the Servicer describing the Issuer's election to prepay the Notes or portion thereof in the form attached hereto as Exhibit C. With respect to each Class of Notes subject to a Voluntary Prepayment, such Voluntary Prepayment shall be made pro rata among such Class.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)With respect to any Voluntary Prepayment in part, on or prior to the related Voluntary Prepayment Date, the Issuer shall deposit into the Collection Account, an amount equal to the sum of (i) the amount of outstanding principal of the Notes being prepaid, (ii) all accrued and unpaid interest thereon and (iii) the applicable Make Whole Amount, if any. Such partial Voluntary Prepayment will be distributed by the Indenture Trustee on the related Voluntary Prepayment Date in accordance with the written direction of the Servicer to the holders of the Notes identified by the Issuer in the Notice of Prepayment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)With respect to a Voluntary Prepayment of all outstanding Notes in full, on or prior to the related Voluntary Prepayment Date, the Issuer will be required to deposit into the Collection Account an amount equal to (i) the sum of (A) the Aggregate Outstanding Note Balance, (B) all accrued and unpaid interest thereon, (C) the Make Whole Amount, if any, (D) the Note Balance Write-Down Amount, if any, (E) the Deferred Interest Amount, if any, (F) the Post-ARD Additional Interest Amount, if any, (G) the Deferred Post-ARD Additional Interest Amount, if any, and (H) all amounts owed to the Indenture Trustee, the Manager, the Servicer, the Backup Servicer, the Transition Manager and any other parties to the Transaction Documents, minus (ii) the sum of the amounts then on deposit in the Reserve Account, the Section 25D

[\*\*\*] = Certain information has been excluded from this exhibit because it is both not material and would likely cause harm to the company if publicly disclosed.

Interest Account and the Equipment Replacement Reserve Account. The Indenture Trustee will make distributions on the related Voluntary Prepayment Date in accordance with the Priority of Payments (without giving effect to clauses (vii) through (xi) thereof) and solely as specified in the related Voluntary Prepayment Servicer Report and to the extent the Aggregate Outstanding Note Balance is prepaid and all other obligations of the Issuer under the Transaction Documents have been paid, release any remaining assets in the Trust Estate to, or at the direction of, the Issuer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)If a Voluntary Prepayment Date occurs prior to the Make Whole Determination Date for a Class of Notes, the Issuer will be required to pay the Noteholders the applicable Make Whole Amount. No Make Whole Amount will be due to the Noteholders if a Voluntary Prepayment is made on or after the Make Whole Determination Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)If the Issuer elects to rescind the Voluntary Prepayment, it must give written notice to the Indenture Trustee of such determination at least two Business Days prior to the Voluntary Prepayment Date. If a Voluntary Prepayment of the Notes has been rescinded pursuant to this Section 6.01(e), the Indenture Trustee shall provide notice of such rescission to the registered owner of each Note which had been subject to the rescinded redemption at the address shown on the Note Register maintained by the Note Registrar with copies to the Issuer, Sunnova Energy, the Depositor and the Rating Agencies.

*Section 6.02.&nbsp;&nbsp;&nbsp;&nbsp;Notice of Voluntary Prepayment.* Any Notice of Voluntary Prepayment received by the Indenture Trustee from the Issuer shall be made available by the Indenture Trustee not less than twenty days and not more than thirty days prior to the date fixed for prepayment to the registered owner of each Note to be prepaid with copies to the Issuer, Sunnova Energy, the Servicer and the Rating Agencies. Failure to make such Notice of Prepayment available to any Noteholder, or any defect therein, shall not affect the validity of any Proceedings for the prepayment of other Notes. If a Voluntary Prepayment has been rescinded pursuant to Section 6.01(e), and to the extent the Indenture Trustee had made notice of the Voluntary Prepayment available, the Indenture Trustee shall make available notice of such rescission to the registered owner of each Note which had been subject to the rescinded Voluntary Prepayment with copies to the Issuer, Sunnova Energy, the Servicer and the Rating Agencies.

Any notice made available as provided in this Section shall be conclusively presumed to have been duly given, whether or not the registered owner of such Notes accesses the notice.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)No provision of this Indenture shall be construed to relieve the Indenture Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h)In no event shall the Indenture Trustee have any obligations or duties under or have any liabilities whatsoever to Noteholders under ERISA.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)In no event shall the Indenture Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities; it being understood that the Indenture Trustee shall resume performance as soon as practicable under the circumstances.

*Section 9.07.&nbsp;&nbsp;&nbsp;&nbsp;Unconditional Right of Noteholders to Receive Principal and Interest*. The Holders of the Notes shall have the right, which is absolute and unconditional, subject to the express terms of this Indenture, to receive payment of principal and interest on such Notes, subject to the respective relative priorities provided for in this Indenture, as such principal and interest becomes due and payable from the Trust Estate and, subject to Section 9.06, to institute Proceedings for the enforcement of any such payment, and such right shall not be impaired except as expressly permitted herein without the consent of such Holders.

The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

*Section 9.10.&nbsp;&nbsp;&nbsp;&nbsp;Delay or Omission; Not Waiver*. No delay or omission of the Indenture Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or any acquiescence therein.

*Section 9.11.&nbsp;&nbsp;&nbsp;&nbsp;Control by Noteholders*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)with respect to a covenant or provision hereof which under Article X cannot be modified or amended without the consent of the Holder of each Outstanding Note affected.

Upon any such waiver, such Default, Event of Default, Acceleration Event, Servicer Termination Event or Manager Termination Event shall cease to exist, and any Default, Event of Default, Acceleration Event, Servicer Termination or Manager Termination Event or other consequence arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default, Event of Default, Servicer Termination Event or Manager Termination Event or impair any right consequent thereon.

*Section 9.13.&nbsp;&nbsp;&nbsp;&nbsp;Undertaking for Costs*. All parties to this Indenture agree, and each Noteholder and each Note Owner by its acceptance of a Note shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Indenture Trustee for any action taken, suffered or omitted by it as Indenture Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 9.13 shall not apply to any suit instituted by the Indenture Trustee or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of or interest on any Note on or after the Rated Final Maturity expressed in such Note.

The Issuer covenants (to the extent that it may lawfully do so) that it will not, at any time, insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Issuer (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Indenture Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

*Section 9.15.&nbsp;&nbsp;&nbsp;&nbsp;Sale of Trust Estate*. (a) The power to effect any sale of any portion of the Trust Estate pursuant to this Article IX shall not be exhausted by any one or more sales as to any portion of the Trust Estate remaining unsold, but shall continue unimpaired until the entire Trust Estate securing the Notes shall have been sold or all amounts payable on the Notes and under this Indenture with respect thereto shall have been paid. The Indenture Trustee, acting on its own or through an agent, may from time to time postpone any sale by public announcement made at the time and place of such sale.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)The Indenture Trustee shall not, in any private sale, sell to a third party the Trust Estate, or any portion thereof unless the Super-Majority Noteholders of the Controlling Class direct the Indenture Trustee, in writing, to make such sale or unless either (i) the proceeds of such sale or liquidation are sufficient to discharge in full the amounts then due and unpaid upon the Notes for principal and accrued interest and the fees and all other amounts required to be paid pursuant the Priority of Payments or (ii) the Holders of 100% of the principal amount of each Class of Notes then Outstanding consent thereto. Notwithstanding the foregoing, prior to the consummation of any sale of the Trust Estate (either private or public), the Indenture Trustee shall first offer the Originator the opportunity to purchase the Trust Estate for a purchase price equal to the greater of (x) the fair market value of the Trust Estate and (y) the aggregate outstanding note balance of the Notes, plus accrued interest thereon and fees owed thereto (such right, the "*Right of First Refusal*"). If the Originator does not exercise its Right of First Refusal within two Business Days of receipt thereof, then the Indenture Trustee shall sell the Trust Estate as otherwise set forth in this Section 9.15; *provided*, *further*, that if the Originator does not exercise its Right of First Refusal and the Indenture Trustee elects to sell the Trust Estate in a private sale to a third party, then prior to the sale thereof, the Indenture Trustee shall offer the Originator the opportunity to purchase the Trust Estate for the purchase price being offered by such third party, and the Originator shall have two Business Days to accept such offer.

The Notes need not be produced in order to complete any such sale, or in order for the net proceeds of such sale to be credited against the Notes. The Indenture Trustee or the Noteholders may hold, lease, operate, manage or otherwise deal with any property so acquired in any manner permitted by law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)The Indenture Trustee shall execute and deliver an appropriate instrument of conveyance transferring its interest in any portion of the Trust Estate in connection with a sale thereof. In addition, the Indenture Trustee is hereby irrevocably appointed the agent and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)The method, manner, time, place and terms of any sale of all or any portion of the Trust Estate shall be commercially reasonable.

*Section 9.16.&nbsp;&nbsp;&nbsp;&nbsp;Action on Notes*. The Indenture Trustee's right to seek and recover judgment on the Notes or under this Indenture shall not be affected by the seeking, obtaining or application of any other relief under or with respect to this Indenture.

*Section 12.01.&nbsp;&nbsp;&nbsp;&nbsp;Compliance Certificates and Opinions; Furnishing of Information.* Upon any application or request by the Issuer to the Indenture Trustee to take any action under any provision of this Indenture (except with respect to ordinary course actions under this Indenture and except as otherwise specifically provided in this Indenture), the Issuer at the request of the Indenture Trustee shall furnish to the Indenture Trustee a certificate describing that all conditions precedent, if any, provided for in this Indenture relating to the proposed action have been complied with and an Opinion of Counsel describing that, in the opinion of such counsel, all such conditions precedent, if any, have been complied with, except that in the case of any such application or request as to which the furnishing of certificates and Opinions of Counsel are specifically required by any provision of this Indenture relating to such particular application or request, no additional certificate or Opinion of Counsel need be furnished.

*Section 12.02.&nbsp;&nbsp;&nbsp;&nbsp;Form of Documents Delivered to Indenture Trustee.* (a) If several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Any certificate or opinion of an Authorized Officer of the Issuer may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by outside counsel, unless such Authorized Officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such certificate or opinion or any Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an Authorized Officer of any relevant Person, describing that the information with respect to such factual matters is in the possession of such Person, unless such officer or counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous. Any Opinion of Counsel may be based on the written opinion of other counsel, in which event such Opinion of Counsel shall be accompanied by a copy of such other counsel's opinion and shall include a statement to the effect that such counsel believes that such counsel and the Indenture Trustee may reasonably rely upon the opinion of such other counsel.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Where any Person is required to make, give or execute two or more applications, requests, consents, notices, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Wherever in this Indenture, in connection with any application or certificate or report to the Indenture Trustee, it is provided that the Issuer, the Servicer or the Manager shall deliver any document as a condition of the granting of such application, or as evidence of the

[\*\*\*] = Certain information has been excluded from this exhibit because it is both not material and would likely cause harm to the company if publicly disclosed.

------

Issuer's, the Servicer's or the Manager's compliance with any term hereof, it is intended that the truth and accuracy, at the time of the granting of such application or at the effective date of such notice or report (as the case may be), of the facts and opinions stated in such document shall in such case be conditions precedent to the right of the Issuer to have such application granted or to the sufficiency of such notice or report. The foregoing shall not, however, be construed to affect the Indenture Trustee's right to rely upon the truth and accuracy of any statement or opinion contained in any such document as provided in Section 7.01(b)(ii).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)Wherever in this Indenture it is provided that the absence of the occurrence and continuation of a Default, an Event of Default, a Servicer Termination Event or a Manager Termination Event is a condition precedent to the taking of any action by the Indenture Trustee at the request or direction of the Issuer, then notwithstanding that the satisfaction of such condition is a condition precedent to the Issuer's or the Indenture Trustee's right to make such request or direction, the Indenture Trustee shall be protected in acting in accordance with such request or direction if a Responsible Officer of the Indenture Trustee does not have actual knowledge of the occurrence and continuation of such Default, Event of Default, Servicer Termination Event or Manager Termination Event.

*Section 12.03.&nbsp;&nbsp;&nbsp;&nbsp;Acts of Noteholders.* (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Noteholders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Noteholders in person or by an agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Indenture Trustee, and, where it is hereby expressly required, to the Issuer. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "*Act*" of the Noteholders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 7.01) conclusive in favor of the Indenture Trustee and the Issuer, if made in the manner provided in this Section 12.03.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by the certificate of any notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Whenever such execution is by an officer of a corporation or a member of a limited liability company or a partnership on behalf of such corporation, limited liability company or partnership, such certificate or affidavit shall also constitute sufficient proof of his authority.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)The ownership of Notes shall be proved by the Note Register.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Any request, demand, authorization, direction, notice, consent, waiver or other action by the Holder of any Notes shall bind the Holder of every Note issued upon the registration or transfer thereof or in exchange therefor or in lieu thereof, with respect to anything done, omitted or suffered to be done by the Indenture Trustee or the Issuer in reliance thereon, whether or not notation of such action is made upon such Notes.

*Section 12.04.&nbsp;&nbsp;&nbsp;&nbsp;Notices, Etc.* Any request, demand, authorization, direction, notice, consent, waiver or act of Noteholders or other documents provided or permitted by this Indenture to be made upon, given or furnished to, or filed with:

Notices delivered to the Rating Agencies shall be by electronic delivery to the email address set forth above where information is available in electronic format. In addition, upon the written request of any beneficial owner of a Note, the Indenture Trustee shall provide to such beneficial owner copies of such notices, reports or other information delivered, in one or more of the means requested, by the Indenture Trustee hereunder to other Persons as such beneficial owner may reasonably request.

*Section 12.05.&nbsp;&nbsp;&nbsp;&nbsp;Notices and Reports to Noteholders; Waiver of Notices.* (a) Where this Indenture provides for notice to Noteholders of any event or the mailing of any report to the Noteholders, such notice or report shall be written and shall be sufficiently given (unless otherwise herein expressly provided) if mailed, first-class, postage-prepaid, to each Noteholder affected by such event or to whom such report is required to be mailed or sent via electronic mail, at the address or electronic mail address of such Noteholder as it appears on the Note Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice or the mailing of such report. In any case where a notice or report to Noteholders is mailed in the manner provided above, neither the failure to mail such notice or report, nor any defect in any notice or report so mailed, to any particular Noteholder shall affect the sufficiency of such notice or report with respect to other Noteholders, and any notice or report which is mailed in the manner herein provided shall be conclusively presumed to have been duly given or provided.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Where this Indenture provides for notice in any manner, such notice may be waived in writing by any Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Noteholders shall be filed with the Indenture Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)If, by reason of the suspension of regular mail service as a result of a strike, work stoppage or similar activity, it shall be impractical to mail notice of any event to the Noteholders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Indenture Trustee shall be deemed to be a sufficient giving of such notice.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)The Indenture Trustee shall promptly upon written request furnish to each Noteholder each Monthly Servicer Report and, unless directed to do so under any other provision of this Indenture or any other Transaction Document (in which case no request shall be necessary), a copy of all reports, financial statements and notices received by the Indenture Trustee pursuant to this Indenture and the other Transaction Documents, but only with the use of a password provided by the Indenture Trustee; *provided, however,* the Indenture Trustee shall have no obligation to provide such information described in this Section 12.05 until it has received the requisite information from the Issuer or the Servicer. The Indenture Trustee will

make no representation or warranties as to the accuracy or completeness of such documents and will assume no responsibility therefor. The Indenture Trustee's internet website will initially be located at www.wilmingtontrustconnect.com or at such other address as the Indenture Trustee shall notify the parties to the Indenture from time to time.

*Section 12.06.&nbsp;&nbsp;&nbsp;&nbsp;Rules by Indenture Trustee.* The Indenture Trustee may make reasonable rules for any meeting of Noteholders.

*Section 12.07.&nbsp;&nbsp;&nbsp;&nbsp;Issuer Obligation.* Each of the Indenture Trustee and each Noteholder accepts that the enforcement against the Issuer under this Indenture and under the Notes shall be limited to the assets of the Issuer, whether tangible or intangible, real or person (including the Trust Estate) and the proceeds thereof. No recourse may be taken, directly or indirectly, against (a) any member, manager, officer, employee, trustee, agent or director of the Issuer or of any predecessor of the Issuer, (b) any member, manager, beneficiary, officer, employee, trustee, agent, director or successor or assign of a holder of a member or limited liability company interest in the Issuer, or (c) any incorporator, subscriber to capital stock, stockholder, officer, director, employee or agent of the Indenture Trustee or any predecessor or successor thereof, with respect to the Issuer's obligations with respect to the Notes or any of the statements, representations, covenants, warranties or obligations of the Issuer under this Indenture or any Note or other writing delivered in connection herewith or therewith.

*Section 12.08.&nbsp;&nbsp;&nbsp;&nbsp;Enforcement of Benefits.* The Indenture Trustee for the benefit of the Noteholders shall be entitled to enforce and, at the written direction (electronic means shall be sufficient) of and with indemnity by the Super-Majority Noteholders of the Controlling Class, the Indenture Trustee shall enforce the covenants and agreements of the Manager contained in the Management Agreement, the Servicer contained in the Servicing Agreement, Sunnova ABS Holdings X and the Depositor contained in the Contribution Agreement, the Performance Guarantor in the Performance Guaranty and each other Transaction Document.

*Section 12.09.&nbsp;&nbsp;&nbsp;&nbsp;Effect of Headings and **Table of Contents**.* The Section and Section headings herein and the **Table of Contents** are for convenience only and shall not affect the construction hereof.

*Section 12.10.&nbsp;&nbsp;&nbsp;&nbsp;Successors and Assigns.* All covenants and agreements in this Indenture by the Issuer and the Indenture Trustee shall bind their respective successors and assigns, whether so expressed or not.

*Section 12.11.&nbsp;&nbsp;&nbsp;&nbsp;Separability; Entire Agreement.* If any provision in this Indenture or in the Notes shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. Furthermore, in lieu of such illegal, invalid or unenforceable provision, there shall be added automatically as part of this Indenture, a provision as similar in its terms and purpose to such illegal, invalid or unenforceable provision as may be possible and be legal, valid and enforceable. This Indenture reflects the entire agreement with respect to the matters covered by this Indenture and supersedes any prior agreements, commitments, drafts, communication, discussions and understandings, oral or written, with respect thereto.

*Section 12.12.&nbsp;&nbsp;&nbsp;&nbsp;Benefits of Indenture.* Nothing in this Indenture or in the Notes, expressed or implied, shall give to any Person, other than the parties hereto and their successors hereunder, any separate trustee or co-trustee appointed under Section 7.13 and the Noteholders, any benefit or any legal or equitable right, remedy or claim under this Indenture.

*Section 12.13.&nbsp;&nbsp;&nbsp;&nbsp;Legal Holidays.* If the date of any Payment Date or any other date on which principal of or interest on any Note is proposed to be paid or any date on which mailing of notices by the Indenture Trustee to any Person is required pursuant to any provision of this Indenture, shall not be a Business Day, then (notwithstanding any other provision of the Notes or this Indenture) payment or mailing of such notice need not be made on such date, but may be made or mailed on the next succeeding Business Day with the same force and effect as if made or mailed on the nominal date of any such Payment Date or other date for the payment of principal of or interest on any Note, or as if mailed on the nominal date of such mailing, as the case may be, and in the case of payments, no interest shall accrue for the period from and after any such nominal date, provided such payment is made in full on such next succeeding Business Day.

*Section 12.14.&nbsp;&nbsp;&nbsp;&nbsp;Governing Law; Jurisdiction; Waiver of Jury Trial.* (a) This Indenture and each Note shall be construed in accordance with and governed by the substantive laws of the State of New York (including New York General Obligations Laws §§ 5-1401 and 5-1402, but otherwise without regard to conflicts of law provisions thereof, except with regard to the UCC) applicable to agreements made and to be performed therein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)TO THE EXTENT PERMITTED BY APPLICABLE LAW, EACH PARTY HERETO AND EACH NOTEHOLDER BY ACCEPTANCE OF A NOTE IRREVOCABLY WAIVES ALL RIGHT OF TRIAL BY JURY IN ANY ACTION PROCEEDING OR COUNTERCLAIM BASED ON, OR ARISING OUT OF, UNDER OR IN CONNECTION WITH, THIS INDENTURE, ANY OTHER DOCUMENT IN CONNECTION HEREWITH OR ANY MATTER ARISING HEREUNDER OR THEREUNDER.

*Section 12.15.&nbsp;&nbsp;&nbsp;&nbsp;Electronic Signatures and Counterparts.* This Indenture may be executed in multiple counterparts (including electronic PDF), each of which shall be an original and all of which taken together shall constitute but one and the same agreement. This Indenture shall be valid, binding, and enforceable against a party only when executed by an authorized individual on behalf of the party by means of (i) an electronic signature that complies with the federal Electronic Signatures in Global and National Commerce Act, state enactments of the Uniform Electronic Transactions Act, and/or any other relevant electronic signatures law, in each case to the extent applicable; (ii) an original manual signature; or (iii) a faxed, scanned, or photocopied manual signature; provided, execution by electronic signature as contemplated in clause (i) shall be limited to instances of force majeure or other circumstances that make execution by such means necessary, unless the parties otherwise agree.

The Class A Notes are issuable only in registered form in denominations as provided in the Indenture and subject to certain limitations therein set forth. At the option of the Class A Noteholder, Class A Notes may be exchanged for Class A Notes of like terms, in any authorized denominations and of like aggregate principal amount, upon surrender of the Notes to be exchanged at the Corporate Trust Office of the Indenture Trustee, subject to the terms and conditions of the Indenture.

This Certifies That Sunnova Helios X Issuer, LLC, a Delaware limited liability company (hereinafter called the "*Issuer*"), which term includes any successor entity under the Indenture, dated as of November 10, 2022 (the "*Indenture*"), between the Issuer and Wilmington Trust, National Association, as indenture trustee (together with any successor thereto, hereinafter called the "*Indenture Trustee*"), for value received, hereby promises to pay to the Registered Owner named above or registered assigns, subject to the provisions hereof and of the Indenture, (A) the interest based on the Interest Accrual Period at the Note Rate defined in the Indenture, on each Payment Date beginning in December 2022 (or, if such day is not a Business Day, the next succeeding Business Day), and (B) principal on each Payment Date in the manner and subject to the Priority of Payments or the Acceleration Event Priority of Payments, as applicable, as set forth in the Indenture; *provided, however*, that the Notes are subject to prepayment as set forth in the Indenture.

[\*\*\*] = Certain information has been excluded from this exhibit because it is both not material and would likely cause harm to the company if publicly disclosed.

as set forth in the Indenture. The Notes are secured by the Trust Estate (as defined in the Indenture).

Reference is hereby made to the Indenture and all indentures supplemental thereto for a statement of the respective rights thereunder of the Issuer, the Indenture Trustee and the Holders of the Notes and the terms upon which the Notes are to be authenticated and delivered. All terms used in this Note which are not defined herein shall have the meanings assigned to them in the Indenture.

The obligation of the Issuer to repay the Notes is a limited, nonrecourse obligation secured only by the Trust Estate. All payments of principal of and interest on the Class B Notes shall be made only from the Trust Estate, and each Noteholder and each Note Owner, by its acceptance of this Class B Note, agrees that it shall be entitled to payments solely from such Trust Estate pursuant to the terms of the Indenture. The actual Outstanding Note Balance on this Class B Note may be less than the principal balance indicated on the face hereof. The actual Outstanding Note Balance on this Class B Note at any time may be obtained from the Indenture Trustee.

With respect to payment of principal of and interest on the Class B Notes, the Indenture provides the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp;Until fully paid, principal payments on the Class B Notes will be made on each Payment Date in an amount, at the time, and in the manner provided in the Indenture. The Outstanding Note Balance of each Class B Note shall be payable no later than the Rated Final Maturity thereof unless the Outstanding Note Balance of such Class B Note becomes due and payable at an earlier date pursuant to the Indenture, and in each case such payment shall be made in an amount and in the manner provided in the Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp;The Class B Notes shall bear interest on the Outstanding Note Balance of the Class B Notes and accrued but unpaid interest thereon, at the applicable Note Rate. The Interest Distribution Amounts with respect to the Class B Notes shall be payable on each Payment Date to the extent that the Collection Account then contains sufficient amounts to pay such Interest Distribution Amounts pursuant to Section 5.07 of the Indenture. Each Interest Distribution Amount will accrue on the basis of a 360 day year consisting of twelve 30 day months.

All payments of interest and principal on the Class B Notes on the applicable Payment Date shall be paid to the Person in whose name such Class B Note is registered at the close of business as of the Record Date for such Payment Date in the manner provided in the Indenture. All reductions in the Outstanding Note Balance of a Class B Note (or one or more Predecessor Notes) effected by full or partial payments of installments of principal shall be binding upon all past, then current, and future Holders of such Class B Note and of any Class B Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof, whether or not such payment is noted on such Class B Note.

The Rated Final Maturity of the Notes is the Payment Date in November 2049 unless the Notes are earlier prepaid in whole or accelerated pursuant to the Indenture. The Indenture Trustee shall pay to each Class B Noteholder of record on the preceding Record Date either (i) by wire transfer, in immediately available funds to the account of such Class B Noteholder at

a bank or other entity having appropriate facilities therefor, if such Class B Noteholder shall have provided to the Indenture Trustee appropriate written instructions at least five Business Days prior to the related Payment Date (which instructions may remain in effect for subsequent Payment Dates unless revoked by the Class B Noteholder), or (ii) if not, by check mailed to such Class B Noteholder at the address of such Class B Noteholder appearing in the Note Register, the amounts to be paid to such Class B Noteholder pursuant to such Class B Noteholder's Notes; provided, that so long as the Class B Notes are registered in the name of the Securities Depository such payments shall be made to the nominee thereof in immediately available funds.

The Class B Notes shall be subject to voluntary prepayment at the option of the Issuer in the manner and subject to the provisions of the Indenture. Whenever by the terms of the Indenture, the Indenture Trustee is required to prepay the Class B Notes, and subject to and in accordance with the terms of Article VI of the Indenture, the Indenture Trustee shall give notice of the prepayment in the manner prescribed by the Indenture.

Subject to certain restrictions contained in the Indenture, (i) the Class B Notes are issuable in the minimum denomination of $100,000 and integral multiples of $1,000 in excess thereof (provided, that one Class B Note may be issued in an additional amount equal to any remaining portion of the Initial Outstanding Note Balance) and (ii) the Class B Notes may be exchanged for a like aggregate principal amount of Class B Notes of authorized denominations of the same maturity.

The final payment on any Definitive Note shall be made only upon presentation and surrender of the Note at the Corporate Trust Office of the Indenture Trustee.

The Class B Noteholders shall have no right to enforce the provisions of the Indenture or to institute action to enforce the covenants therein, or to take any action with respect to any Event of Default, or to institute, appear in or defend any Proceedings with respect thereto, except as provided in the Indenture.

The Class B Notes may be exchanged, and their transfer may be registered, by the Noteholders in person or by their attorneys duly authorized in writing at the Corporate Trust Office of the Indenture Trustee only in the manner, subject to the limitations provided in the Indenture, and upon surrender and cancellation of the Class B Notes. Upon exchange or registration of such transfer, a new registered Class B Note or Notes evidencing the same outstanding principal amount will be executed in exchange therefor.

All amounts collected as payments on the Trust Estate or otherwise shall be applied in the order of priority specified in the Indenture.

Each Person who has or who acquires any Ownership Interest in a Class B Note shall be deemed by the acceptance or acquisition of such Ownership Interest to have agreed to be bound by the provisions of the Indenture. A Noteholder may not sell, offer for sale, assign, pledge, hypothecate or otherwise transfer or encumber all or any part of its interest in the Class B Notes except pursuant to an effective registration statement covering such transaction under the Securities Act of 1933, as amended, and effective qualification or registration under all applicable State securities laws and regulations or under an exemption from registration under said Securities Act and said State securities laws and regulations.

The Class B Notes and all obligations with respect thereto, including obligations under the Indenture, will be limited recourse obligations of the Issuer payable solely from the Trust Estate. Neither the Issuer, Sunnova Intermediate Holdings, Sunnova ABS Holdings X, the Performance Guarantor, the Depositor, the Manager, the Transition Manager, the Servicer, the Backup Servicer, the Custodian, the Note Registrar, the Indenture Trustee in its individual capacity or in its capacity as Indenture Trustee, nor any of their respective Affiliates, agents, partners, beneficiaries, officers, directors, stockholders, stockholders of partners, employees or successors or assigns, shall be personally liable for any amounts payable, or performance due, under the Notes or the Indenture. Without limiting the foregoing, each Noteholder and each Note Owner of any Class B Note by its acceptance thereof, and the Indenture Trustee, shall be deemed to have agreed (i) that it shall look only to the Trust Estate to satisfy the Issuer's obligations under or with respect to a Class B Note or the Indenture, including but not limited to liabilities under Article V of the Indenture and liabilities arising (whether at common law or equity) from breaches by the Issuer of any obligations, covenants and agreements herein or, to the extent enforceable, for any violation by the Issuer of applicable State or federal law or regulation, provided that, the Issuer shall not be relieved of liability hereunder with respect to any misrepresentation in the Indenture or any Transaction Document, or fraud, of the Issuer and (ii) to waive any rights it may have to obtain a deficiency or other monetary judgment against either the Issuer or any of its principals, directors, officers, beneficial owners, employees or agents (whether disclosed or undisclosed) or their respective assets (other than the Trust Estate). The foregoing provisions of this paragraph shall not (i) prevent recourse to the Trust Estate or any Person (other than the Issuer) for the sums due or to become due under any security, instrument or agreement which is part of the Trust Estate; (ii) constitute a waiver, release or discharge of any indebtedness or obligation evidenced by the Class B Notes or secured by the Indenture, but the same shall continue until paid or discharged; or (iii) prevent the Indenture Trustee from exercising its rights with respect to the Grant, pursuant to the Indenture, of the Issuer's rights under the Transaction Documents. It is further understood that the foregoing provisions of this paragraph shall not limit the right of any Person to name the Indenture Trustee in its capacity as Indenture Trustee under the Indenture or the Issuer as a party defendant in any action or suit or in the exercise of any remedy under the Notes or the Indenture, so long as no judgment in the nature of a deficiency judgment or seeking personal liability shall be asked for or (if obtained) enforced. It is expressly understood that all such liability is hereby expressly waived and released to the extent provided herein as a condition of, and as a consideration for, the execution of the Indenture and the issuance of the Notes.

The remedies of the Holder of this Class B Note as provided herein, in the Indenture or in the other Transaction Documents, shall be cumulative and concurrent and may be pursued solely against the assets of the Trust Estate.

At the option of the Class B Noteholder, Class B Notes may be exchanged for Class B Notes of like terms, in any authorized denominations and of like aggregate principal amount, upon surrender of the Notes to be exchanged at the Corporate Trust Office of the Indenture Trustee, subject to the terms and conditions of the Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)The Initial Purchaser will indemnify and hold harmless the Sunnova Entities and each of their affiliates, directors, officers and employees, each person, if any, who controls the Issuer within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which they or any of them may become subject, under the Securities Act or the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any document comprising a part of the Offering Document or any amendment or supplement thereto, or arise out of or are based upon the omission or the alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Issuer by the Initial Purchaser specifically for use therein, and will reimburse any documented legal or other expenses reasonably incurred by the Sunnova Entities and such affiliate, director, officer, employee, agent or controlling person in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred, including but not limited to the costs of defending itself against any claim or bringing any claim to enforce the indemnification or other obligations of the Initial Purchaser, it being understood and agreed that the only such information furnished by the Initial Purchaser consists of the first sentence of the

second paragraph and the second sentence of the second to last paragraph under the caption "PLAN OF DISTRIBUTION" in the Preliminary Offering Circular and the Offering Circular (collectively, the "**Initial Purchaser Information**"); <u>provided</u>, <u>however</u>, that the Initial Purchaser shall not be liable for any losses, claims, damages or liabilities arising out of or based upon the Issuer's failure to perform its obligations under Section 5(a) hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to either subsection (a) or (b), such person (the "**indemnified party**") promptly shall notify the person against whom such indemnity may be sought (the "**indemnifying party**") in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceedings and shall pay the fees and disbursements of not more than one such counsel related to such proceeding; <u>provided</u>, <u>however</u>, that the failure of any indemnified party to provide such notice to the indemnifying party shall not relieve the indemnifying party of its obligations under this Section 7 unless such failure results in the forfeiture by the indemnifying party of substantial rights and defenses. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless: (i) the indemnifying party and the indemnified party agree on the retention of such counsel at the indemnifying party's expense, (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action or (iii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one counsel (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed promptly as they are incurred. Such counsel shall be designated in writing by Sunnova Energy, in the case of parties indemnified pursuant to subsection (a), and by the Initial Purchaser, in the case of parties indemnified pursuant to subsection (b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, such consent not to be unreasonably withheld, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to promptly indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of any judgment or otherwise seek to terminate any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity or contribution could have been sought hereunder by such indemnified party, unless such settlement, consent, compromise or termination (i) includes an unconditional written release, in form and substance reasonable satisfactory to the indemnified party, of such indemnified party from all liability on claims that are the subject matter of such proceeding and (ii) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of such indemnified party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party, as incurred, as a result of the expenses, losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuer, the Depositor and Sunnova Energy on the one hand and the Initial

Purchaser on the other from the offering of the Underwritten Notes or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Issuer, the Depositor and Sunnova Energy on the one hand and the Initial Purchaser on the other in connection with the statements or omissions which resulted in such expenses, losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Issuer, the Depositor and Sunnova Energy on the one hand and the Initial Purchaser on the other, in connection with the offering of the Underwritten Notes, shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses other than any Initial Purchaser Compensation (as defined below)) received by the Issuer and the total discounts and commissions received by the Initial Purchaser (the "**Initial Purchaser Compensation**") bear to the aggregate initial offering prices of the Underwritten Notes. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Issuer, the Depositor, Sunnova Energy, or the Initial Purchaser and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the total discounts and commission received by it exceed the amount of any damages that it otherwise has been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)The obligations of the Issuer, the Depositor and Sunnova Energy under this Section shall be in addition to any liability which the Issuer, the Depositor or Sunnova Energy may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the Initial Purchaser within the meaning of the Securities Act or the Exchange Act; and the obligations of the Initial Purchaser under this Section shall be in addition to any liability which such Initial Purchaser may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the Issuer, the Depositor or Sunnova Energy within the meaning of the Securities Act or the Exchange Act.

Section 8.<u>Default of Initial Purchaser</u>. If the Initial Purchaser defaults in its obligations to purchase Underwritten Notes hereunder and the aggregate principal amount of Underwritten Notes that such defaulting Initial Purchaser agreed but failed to purchase does not exceed 10% of the total principal amount of Underwritten Notes, the non-defaulting Initial Purchaser may make arrangements satisfactory to the Issuer for the purchase of such Underwritten Notes by other persons, including any other Initial Purchaser, but if no such arrangements are made by the Closing Date, the non-defaulting Initial Purchaser shall be obligated to purchase the Underwritten Notes that such defaulting Initial Purchaser agreed but failed to purchase. If the Initial Purchaser so defaults and the principal amount of Underwritten Notes with respect to which such default occurs exceeds 10% of the total principal amount of Underwritten Notes and arrangements satisfactory to the non-defaulting Initial Purchaser and the Issuer for the purchase of such Underwritten Notes by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Initial Purchaser or the Issuer, except as provided in Section 9 hereof. As used in this Agreement, the term "Initial Purchaser" includes any person substituted for the Initial Purchaser under this Section 8. Nothing herein will relieve a defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

If for any reason the purchase of the Underwritten Notes by the Initial Purchaser is not consummated, each of the Issuer, the Depositor and Sunnova Energy shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 5 hereof (except in the event of a breach of this Agreement by the Initial Purchaser) and the respective obligations of the Issuer, the Depositor, Sunnova Energy and the Initial Purchaser pursuant to Section 7 hereof shall remain in effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)In the event that the Initial Purchaser that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Initial Purchaser that is a Covered Entity of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any interest and obligation in or under this Agreement, were governed by the laws of the United States or a state of the United States.
