HOUSTON, February 22, 2023 (BUSINESS WIRE) - Sunnova Energy International Inc. ("Sunnova") (NYSE: NOVA), one of the leading Energy as a Service (EaaS) providers, today announced financial results for the fourth quarter and full year ended December 31, 2022.

"We delivered strong growth in the fourth quarter as we placed a record number of customers into service, which brought our total customer additions in 2022 to 87,000, the midpoint of our guidance," said William J. (John) Berger, founder and Chief Executive Officer of Sunnova. "This strong growth trend has carried into 2023, increasing our confidence in our ability to meet or exceed our 2023 guidance targets. Our EaaS business model with an open platform strategy has enabled Sunnova to navigate various macroeconomic challenges. We continue to increase our total addressable market and market share.

Furthermore, as the monopoly utilities continue to increase their rates, we are able to provide our customers with even greater savings through an energy service that is more resilient, reliable, and sustainable."

Fourth Quarter and Full Year 2022 Results

Revenue increased to $195.6 million, or by $130.6 million, for the three months ended December 31, 2022 compared to the three months ended December 31, 2021. This increase was primarily the result of an increased number of solar energy systems in service and the sale of inventory to our dealers or other parties.

Revenue increased to $557.7 million, or by $315.9 million, for the year ended December 31, 2022 compared to the year ended December 31, 2021. This increase was primarily the result of an increased number of solar energy systems in service, the April 2021 acquisition of SunStreet, and the sale of inventory to our dealers or other parties.

Total operating expense, net increased to $212.4 million, or by $138.4 million for the three months ended December 31, 2022 compared to the three months ended December 31, 2021. This increase was primarily the result of an increased number of solar energy systems in service, an increase in cost of revenue - inventory sales due to the sale of inventory to our dealers or other parties, and higher general and administrative expense.

Total operating expense, net increased to $639.2 million, or by $342.6 million for the year ended December 31, 2022 compared to the year ended December 31, 2021. This increase was primarily the result of an increased number of solar energy systems in service, the April 2021 acquisition of SunStreet, an increase in cost of revenue - inventory sales due to the sale of inventory to our dealers or other parties, and higher general and administrative expense.

Adjusted Operating Expense increased to $64.6 million, or by $23.8 million, for the three months ended December 31, 2022 compared to the three months ended December 31, 2021. This increase was primarily the result of an increased number of solar energy systems in service and higher general and administrative expense.

Adjusted Operating Expense increased to $215.2 million, or by $74.6 million, for the year ended December 31, 2022 compared to the year ended December 31, 2021. This increase was primarily the result of an increased 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 $62.0 million for the three months ended December 31, 2022 compared to a net loss of $31.3 million for the three months ended December 31, 2021. This higher net loss was primarily the result of higher general and administrative expense and an increase in interest expense, net of $31.9 million. This was partially offset by an increase in interest income of $9.4 million due to our larger customer loan portfolio.

Sunnova incurred a net loss of $130.3 million for the year ended December 31, 2022 compared to a net loss of $147.5 million for the year ended December 31, 2021. This lower net loss was primarily the result of an increase in interest income of $25.6 million primarily due to our larger customer loan portfolio, a decrease in loss on extinguishment of long-term debt, net of $9.8 million primarily due to a make-whole payment related to the early repayment of one of our solar asset-backed notes in June 2021, and a decrease in interest expense, net of $8.5 million. This was partially offset by higher general and administrative expense.

Adjusted EBITDA was $25.6 million for the three months ended December 31, 2022 compared to $17.7 million for the three months ended December 31, 2021. Adjusted EBITDA was $119.1 million for the year ended December 31, 2022 compared to $85.9 million for the year ended December 31, 2021. These increases were primarily due to customer growth increasing at a rate faster than expenses.

Customer principal (net of amounts recorded in revenue) and interest payments received from solar loans increased to $24.0 million and $17.4 million, respectively, for the three months ended December 31, 2022, or by $7.1 million and $7.5 million, respectively, compared to the three months ended December 31, 2021. Customer principal (net of amounts recorded in revenue) and interest payments received from solar loans increased to $91.5 million and $56.4 million, respectively, for the year ended December 31, 2022, or by $32.2 million and $22.7 million, respectively, compared to the year ended December 31, 2021. These increases were due to our larger customer loan portfolio.

Liquidity & Capital Resources

As of December 31, 2022, Sunnova had total cash of $546 million, including restricted and unrestricted cash.

2023 Full Year Guidance

Sunnova management reaffirms its 2023 guidance of:

•Customer additions between 115,000 and 125,000;

•Adjusted EBITDA between $235 million and $255 million;

•Customer interest payments received from solar loans between $110 million and $120 million; and

•Customer principal payments received from solar loans, net of amounts recorded in revenue, between $150 million and $190 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 6%.

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.

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 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 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.
