Sunnova Reports Fourth Quarter and Full Year 2023 Financial Results

Fourth Quarter 2023 and Recent Highlights

•Deployed over 34,000 customers in the fourth quarter; bringing total customer count to 419,200 as of December 31, 2023;
•Increased single customer economics as expressed through fully burdened unlevered return;
•Continued to execute a cost reduction plan for 2024 enhancing cash generation; and
•Initiated 2025 cash generation guidance between $200 million and $500 million.

HOUSTON, February 21, 2024 (BUSINESS WIRE) - Sunnova Energy International Inc. ("Sunnova") (NYSE: NOVA), a leading adaptive energy services company, today announced financial results for the fourth quarter and full year ended December 31, 2023.

"In 2023, Sunnova demonstrated good performance across its operations. For the year, we expanded our customer base to 419,200 and hit our 2023 targets for Adjusted EBITDA, interest income, and principal proceeds. Additionally, we increased our single customer economics and unveiled our Global Command Center to enhance customer service, solidifying our position as a leading adaptive energy services company," said William J. (John) Berger, Sunnova's founder and CEO.

"Looking ahead to the remainder of 2024, our focus will be on cash generation driven by cost reductions, asset sales, and expanding margins. By year end, we anticipate the combination of our revised cost structure and increased operating leverage will result in a decrease of over 20% in total Adjusted Operating Expense per customer. Through a combination of securitizations and sales, in 2024 we expect to generate enough cash to provide the working capital needed to hit our growth target, net of operating costs, and exit the year with an annual cash generation run rate between $200 million and $500 million."

Fourth Quarter and Full Year 2023 Results

Revenue was relatively unchanged at $194.2 million for the three months ended December 31, 2023 compared to $195.6 million for the three months ended December 31, 2022.

Revenue increased to $720.7 million, or by $163.0 million, for the year ended December 31, 2023 compared to the year ended December 31, 2022. This increase was primarily the result of an increased number of solar energy systems in service, an increase in direct sales revenue primarily due to an increased focus on direct sales of additional services to existing customers, and an increase in service revenue primarily due to an increase in repair service revenue. This was partially offset by lower inventory sales revenue from the sale of inventory to our dealers or other parties.

Total operating expense, net increased to $290.8 million, or by $78.4 million for the three months ended December 31, 2023 compared to the three months ended December 31, 2022. Total operating expense, net increased to $964.1 million, or by $324.9 million for the year ended December 31, 2023 compared to the year ended December 31, 2022. These increases were primarily the result of an increased number of solar energy systems in service, higher general and administrative expense, higher cost of revenue - other primarily due to an increased focus on direct sales of additional services to existing customers, a write off of goodwill in 2023 as the carrying amount exceeded the fair value, and a decrease in other operating income primarily due to changes in the fair value of certain financial instruments and contingent consideration. This was partially offset by lower cost of revenue - inventory sales from the sale of inventory to our dealers and other parties.

Adjusted Operating Expense increased to $114.9 million, or by $50.3 million, for the three months ended December 31, 2023 compared to the three months ended December 31, 2022. Adjusted Operating Expense increased to $376.5 million, or by $161.3 million, for the year ended December 31, 2023 compared to the year ended December 31, 2022. These increases were primarily the result of an increased number of solar energy systems in service and higher general and administrative expense.

Sunnova incurred a net loss of $234.8 million for the three months ended December 31, 2023 compared to a net loss of $62.0 million for the three months ended December 31, 2022. Sunnova incurred a net loss of $502.4 million for the year ended December 31, 2023 compared to a net loss of $130.3 million for the year ended December 31, 2022. These higher net losses were primarily the result of an increase in interest expense, higher general and administrative expense, a write off of goodwill in 2023 as the carrying amount exceeded the fair value, and a decrease in other operating income primarily due to changes in the fair value of certain financial instruments and contingent consideration. This was partially offset by an increase in interest income primarily due to our larger customer loan portfolio.

1

Adjusted EBITDA was $191.5 million for the three months ended December 31, 2023 compared to $25.6 million for the three months ended December 31, 2022. Adjusted EBITDA was $274.5 million for the year ended December 31, 2023 compared to $119.1 million for the year ended December 31, 2022. These increases were primarily the result of investment tax credit sales, which began in 2023.

Principal proceeds from customer notes receivable (net of amounts recorded in revenue) and proceeds from investments in solar receivables was $46.7 million for the three months ended December 31, 2023 compared to $27.0 million for the three months ended December 31, 2022. Principal proceeds from customer notes receivable (net of amounts recorded in revenue) and proceeds from investments in solar receivables was $158.3 million for the year ended December 31, 2023 compared to $103.8 million for the year ended December 31, 2022. These increases were primarily due to our larger customer loan portfolio.

Interest income was $34.2 million for the three months ended December 31, 2023 compared to $19.4 million for the three months ended December 31, 2022. Interest income was $115.9 million for the year ended December 31, 2023 compared to $59.8 million for the year ended December 31, 2022. These increases were primarily due to our larger customer loan portfolio.

Liquidity & Capital Resources

As of December 31, 2023, Sunnova had total cash of $494.4 million, including restricted and unrestricted cash.

2024 Full Year Guidance

Sunnova management reaffirms its 2024 full year guidance:

•Customer additions between 185,000 and 195,000;
•Adjusted EBITDA between $350 million and $450 million;
•Interest income between $150 million and $190 million; and
•Principal proceeds from customer notes receivable, net of amounts recorded in revenue, and proceeds from investments in solar receivables between $210 million and $250 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.

Forward-Looking Statements

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
8

customers during the initial contract term of our customer agreements, 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 customer agreements. These estimated future cash flows reflect the projected monthly customer payments over the life of our customer agreements and depend on various factors including but not limited to 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 or Sunnova-financed 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.
