Third Quarter 2021 Results

Revenue increased to $68.9 million, or by $18.7 million, for the three months ended September 30, 2021 compared to the three months ended September 30, 2020. Revenue increased to $176.7 million, or by $53.9 million, for the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020. These increases were primarily the result of an increase in the number of solar energy systems in service and the April 2021 acquisition of SunStreet.

Total operating expense, net increased to $77.1 million, or by $28.5 million, for the three months ended September 30, 2021 compared to the three months ended September 30, 2020. Total operating expense, net increased to $222.6 million, or by $82.0 million for the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020. These increases were primarily the result of an increase in the number of solar energy systems in service, the April 2021 acquisition of SunStreet, greater depreciation expense, and higher general and administrative expense.

Adjusted Operating Expense increased to $38.8 million, or by $14.0 million, for the three months ended September 30, 2021 compared to the three months ended September 30, 2020. Adjusted Operating Expense increased to $99.8 million, or by $26.6 million, for the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020. These increases were primarily the result of an increase in the number of solar energy systems in service, the April 2021 acquisition of SunStreet, and higher general and administrative expense.

Sunnova incurred a net loss of $25.9 million for the three months ended September 30, 2021 compared to a net loss of $73.3 million for the three months ended September 30, 2020. This lower net loss was primarily the result of a loss on the extinguishment of debt from the select conversion of convertible senior notes for common stock in the third quarter of 2020 and lower net interest expense in 2021 which was primarily due to decreases in amortization of debt discounts of $2.4 million and interest expense of $1.7 million due to more favorable terms of recent financing transactions.

Sunnova incurred a net loss of $116.3 million for the nine months ended September 30, 2021 compared to a net loss of $179.0 million for the nine months ended September 30, 2020. This lower net loss was primarily the result of a loss on the extinguishment of debt from the select conversion of convertible senior notes for common stock in the third quarter of 2020 and lower net interest expense in 2021 which was primarily due to a decrease in realized losses on interest rate swaps of $37.0 million due to the termination of certain debt facilities in 2020, an increase in unrealized gains on interest rate swaps of $8.3 million and a decrease in amortization of debt discounts of $4.0 million. These were partially offset by an increase in amortization of deferred financing costs of $4.8 million and an increase in general and administrative expense.

Adjusted EBITDA was relatively unchanged at $25.2 million for the three months ended September 30, 2021 compared to $25.4 million for the three months ended September 30, 2020. Adjusted EBITDA was $68.1 million for the nine months ended September 30, 2021 compared to $49.6 million for the nine months ended September 30, 2020, an increase of $18.5 million. This increase was the result of customer growth increasing at a faster rate than expenses.

Customer principal (net of amounts recorded in revenue) and interest payments received from solar loans increased to $14.3 million and $8.9 million, respectively, for the three months ended September 30, 2021, or by $5.1 million and $3.0 million, respectively, compared to the three months ended September 30, 2020. Customer principal (net of amounts recorded in revenue) and interest payments received from solar loans increased to $42.4 million and $23.9 million, respectively, for the nine months ended September 30, 2021, or by $19.3 million and $7.0 million, respectively, compared to the nine months ended September 30, 2020. These increases were the result of our larger customer loan portfolio.

Net cash used in operating activities was $36.2 million for the three months ended September 30, 2021 compared to $18.9 million for the three months ended September 30, 2020. This increase was primarily the result of increases in purchases of inventory and prepaid inventory of $24.3 million.

Net cash used in the operating activities was $146.8 million for the nine months ended September 30, 2021 compared to $101.8 million for the nine months ended September 30, 2020. This increase was primarily the result of increases in purchases of inventory and prepaid inventory of $57.1 million.

Non-GAAP Financial Measures

We present our operating results in accordance with accounting principles generally accepted in the U.S. ("GAAP"). We believe certain financial measures, such as Adjusted EBITDA and Adjusted Operating Expense, which are non-GAAP measures, provide users of our financial statements with supplemental information that may be useful in evaluating our business. We use Adjusted EBITDA and Adjusted Operating Expense as performance measures, and believe investors and securities analysts also use Adjusted EBITDA and Adjusted Operating Expense in evaluating our performance. 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. Therefore, we separately show customer P&I payments. 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. We believe that such non-GAAP measures, when read in conjunction with our operating results presented under GAAP, can be used both to better assess our business from period to period and to better assess our business against other companies in our industry, without regard to financing methods, historical cost basis or capital structure. Our calculation of these non-GAAP financial measures may differ from similarly-titled non-GAAP measures, if any, reported by other companies. In addition, other companies may not publish these or similar measures. Such non-GAAP measures should be considered as a supplement to, and not as a substitute for, financial measures prepared in accordance with GAAP. Sunnova is unable to reconcile projected Adjusted EBITDA and Adjusted Operating Expense to the most comparable financial measures calculated in accordance with GAAP because of fluctuations in interest rates and their impact on our unrealized and realized interest rate hedge gains or losses. Sunnova provides a range for the forecasts of Adjusted EBITDA and Adjusted Operating Expense to allow for the variability in the timing of cash receipts and disbursements, customer utilization of our assets, and the impact on the related reconciling items, many of which interplay with each other. Therefore, the reconciliation of projected Adjusted EBITDA and Adjusted Operating Expense to projected net income (loss) and total operating expense, as the case may be, is not available without unreasonable effort.

Key Terms for Our Key Metrics and Non-GAAP Financial Measures

Estimated Gross Contracted Customer Value. 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 power purchase agreements ("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 solar renewable energy certificates ("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 4%.

Number of Customers. We define number of customers to include every unique individual possessing an in-service product that is subject to a Sunnova lease, PPA or loan agreement, or with respect to which Sunnova is obligated to perform a service under an active agreement between Sunnova and the individual or between Sunnova and a third party. For all solar energy systems installed by us, in-service means the related solar energy system and, if applicable, energy storage system, must have met all the requirements to begin operation and be interconnected to the electrical grid. For all products other than solar energy systems or energy storage systems, which are subject to a loan agreement between Sunnova and a customer, in-service means the customer is obligated to begin making payments to Sunnova under the loan agreement. We do not include in our number of customers any customer possessing a solar energy system or energy storage system under a lease, PPA or loan agreement that has reached mechanical completion but has not received permission to operate from the local utility or for whom we have terminated the contract and removed the solar energy system. We also do not include in our number of customers any customer that has been in default under his or her lease, PPA or loan agreement in excess of six months. 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 the additional services and/or contracts a customer or third party executed for the additional work for the same residence. 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.

Definitions of Non-GAAP Measures

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, 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 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 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, unrealized 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 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.
