In our opinion, the accompanying financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2023 and 2022, and the results of its operations and its cash flows for the years ended December 31, 2023 and 2022 and for the period from December 17, 2021 through December 31, 2021 in accordance with accounting principles generally accepted in the United States of America. Basis for Opinion We conducted our audits in accordance with auditing standards generally accepted in the United States of America (GAAS). Our responsibilities under those standards are further described in the Auditor’s Responsibilities for the Audit of the Financial Statements section of our report. We are required to be independent of the Company and to meet our other ethical responsibilities in accordance with the relevant ethical requirements relating to our audits. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion. Responsibilities of Management for the Financial Statements Management is responsible for the preparation and fair presentation of the financial statements in accordance with accounting principles generally accepted in the United States of America, and for the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free of material misstatement, whether due to fraud or error. In preparing the financial statements, management is required to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year after the date that the financial statements are available to be issued. Auditor’s Responsibilities for the Audit of the Financial Statements Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free of material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance but is not absolute assurance and therefore is not

The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. Misstatements are considered material if there is a substantial likelihood that, individually or in the aggregate, they would influence the judgment made by a reasonable user based on the financial statements. In performing an audit in accordance with GAAS, we:  Exercise professional judgment and maintain professional skepticism throughout the audit.  Identify and assess the risks of material misstatement of the financial statements, whether due to fraud or error, and design and perform audit procedures responsive to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements.  Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control. Accordingly, no such opinion is expressed.  Evaluate the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluate the overall presentation of the financial statements.  Conclude whether, in our judgment, there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for a reasonable period of time. We are required to communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit, significant audit findings, and certain internal control-related matters that we identified during the audit.

A summary of the major agreements related to the Company is set forth below: Limited Liability Company Agreement The Company is governed by a limited liability agreement, or LLCA, executed on December 17, 2021, which was amended on March 18, 2022 and again on August 30, 2023. The LLCA provides for allocations of income, taxable items and available cash related to the Mesquite Sky and Mesquite Star Special facilities, which are 50.01% to Lighthouse Renewable Class A and 49.99% to HASI, except that allocations of available cash are first utilized to pay back member loans, if any. For the TSN1 Facility, allocations of income, taxable items and available cash are 50% to Lighthouse Renewable Class A and 50% to HASI until December 2033, then are 25% to Lighthouse Renewable Class A and 75% to HASI thereafter, also subject to the pay back of member loans, if any. In addition, subsequent to December 31, 2036, up to 100% of Lighthouse Renewable Class A’s cash may be allocated to HASI which provides a reallocation of cash in order to ensure that HASI achieves its target return on investment. If HASI achieves a return above a specified threshold, certain amounts may be allocated to Clearway Renew, through its ownership of the Class C membership interests. In the event that additional working capital is required by the Mesquite Sky Facility, the Mesquite Star Special Facility, or the TSN1 Facility, to cause the assets to be properly operated and maintained and pay for the costs, expenses, obligations and liabilities of the facility, and such amounts are not available from its reserves, then Lighthouse Renewable Class A and HASI have the right, but not the obligation, to participate in member loans to advance needed funds. See note 8, Notes Payable for information regarding member loans issued in 2023. In accordance with the provision of the LLCA, the Class A Member is the Manager, as defined, and conducts the activities of the Company on behalf of the members. The Manager has engaged Clearway Asset Services LLC to perform certain of its duties as Manager. All management services provided are at the direction of the Manager and the Manager retains its obligations with respect to its duties and responsibilities. See note 11, Related Party Transactions, for further detail. In addition, the LLCA establishes both a review committee, which is responsible for material decisions that protect the interests of both the Class A Member and Class B Member, and is comprised of two members appointed by each of the Class A Member and Class B Member, and an operations committee, which is responsible for advising the Company and the review committee with respect to the Company’s operations.

Mesquite Sky Agreements (a) ISDA Master Agreement Mesquite Sky and a third party are parties to an amended ISDA 2002 Master Agreement, dated as of December 30, 2020, and a Side Agreement, dated October 1, 2021, as amended, collectively the Sky Hedge Agreement. Under the Sky Hedge Agreement, Mesquite Sky is party to a 12-year agreement to sell power to a counterparty at a fixed price, which is utilized to manage the risk of fluctuations in market prices on sales of electricity. The energy-related commodity contract is accounted for as a derivative financial instrument as described in note 2(k), Derivative Financial Instruments. The Sky Hedge Agreement contains provisions providing the counterparty a lien on specific assets as collateral. Also see note 4, Accounting for Derivative Instruments and Hedging Activities, for further information. On January 14, 2022, July 27, 2022, and January 27, 2023, Mesquite Sky executed amendments to the energy-related commodity contract under the Sky Hedge Agreement. The amendments permitted the partial net settlement of contracted volumes to be delivered for various settlement intervals from January 16, 2022 through January 31, 2022, August 1, 2022 through August 31, 2022, and February 1, 2023 through February 28, 2023. The Company paid settlement fees to the counterparty for these amendments, which totaled $324 thousand and $3.1 million for the years ended December 31, 2023 and 2022, respectively, and were recorded as a reduction to operating revenues in the consolidated statements of operations. Mesquite Sky was permitted to utilize the tracking account liability to finance the cost of this settlement in 2022 and recorded the amounts as an increase to the tracking account liability. See Tracking Account below for further detail on the tracking account. Tracking Account The energy-related commodity contract contains provisions that allows for Mesquite Sky to receive additional money from the counterparty when the price of electricity at the interconnection point of the Mesquite Sky Facility is less than the price of electricity at the hub where Mesquite Sky is obligated to sell electricity (adjusted for actual generation delivered versus the quantity purchased at the hub). This mismatch is accumulated in a tracking account, which represents a liability that is due to the counterparty at the conclusion of the contract. Mismatch amounts received by Mesquite Sky increase the tracking account liability owed by Mesquite Sky up to the maximum liability of $12.0 million. When the calculated mismatch amount results in Mesquite Sky making a payment to the hedge counterparty, the amount may reduce the tracking account liability but only until the tracking account balance is paid in full. The balance in the tracking account accrues interest daily at a per annum rate equal to the Federal Funds effective published rate for that day plus an applicable margin of 3.0%. The interest incurred is recorded within interest expense in the consolidated statements of operations. Upon termination of the energy-related commodity contract on September 30, 2033, the tracking account balance will be settled between Mesquite Sky and the counterparty. If the tracking account balance is less than zero, then Mesquite Sky shall pay the counterparty the absolute value of the tracking account balance. As of both December 31, 2023 and 2022, Mesquite Sky recorded a liability for the tracking account balance of $12.0 million.

December 31, 2023, a subsidiary of Lighthouse Renewable Class A LLC, issued a letter of credit in favor of the hedge counterparty for $12.2 million. (b) Virtual Power Purchase Agreements Mesquite Sky is party to the following amended renewable energy purchase agreements, referred to as virtual power purchase agreements, or VPPAs, which provide for Mesquite Sky to receive or pay consideration for the delivery of electricity to the interconnection point and to sell the associated renewable energy credits, or RECs, based on the difference between the fixed price per MWh specified in each of the VPPAs and the relevant floating market price for each settlement interval, with upside sharing in the event that the floating market price exceeds the fixed price. Under the terms of the VPPAs, Mesquite Sky has guaranteed certain availability that if not achieved could result in the payment of shortfall amounts.

which generally covers an approximately two-year period commencing upon the completion of the commissioning of each wind turbine, with provisions for one-year renewal terms. Amounts due to Siemens under this agreement of $15.7 million were recorded as accounts payable – trade as of December 31, 2021, of which $11.5 million was paid during 2022, $1.2 million of change order credits were received from Siemens during 2022, and the remaining $3.0 million due to Siemens was recorded as accounts payable – trade as of December 31, 2022, and remained as of December 31, 2023. In February 2024, Mesquite Sky was released from this payment obligation by Siemens and Mesquite Sky’s obligations have been fulfilled under this agreement. (d) Siemens Gamesa Renewable Energy, Inc. Service and Warranty Agreement Mesquite Sky contracted with Siemens to provide certain warranty, maintenance, and repair services for the wind turbines. Payment provisions provide for an annual service fee per turbine plus escalation paid in quarterly installments. On July 11, 2022, Mesquite Sky’s service and warranty agreement with Siemens was amended and restated in its entirety, and further amended on February 23, 2024 to include additional scheduled and unscheduled services and to provide the tools, parts, equipment, and labor necessary to carry out the scheduled and unscheduled services. In addition, the amended and restated agreement provided for an increase in the annual service fee per turbine plus escalation for a selected period, an increase in the availability threshold, set annual limitations on availability liquidated damages, and set the term of the agreement to expire on July 11, 2032, unless extended until December 31, 2032, or terminated early as provided for in the agreement. Total gross fees incurred under this agreement were $3.0 million, $2.1 million, and $30 thousand for the years ended December 31, 2023 and 2022 and the period from December 17, 2021 through December 31, 2021, respectively. These costs are included in cost of operations in the consolidated statements of operations. Pursuant to the terms of the agreement with Siemens, the wind turbines are required to meet certain minimum availability thresholds. Failure to achieve minimum availability, as defined in the agreement, could result in payments due from Siemens to the Company. For the years ended December 31, 2023 and 2022, and the period from December 17, 2021 through December 31, 2021, Mesquite Sky received settlements of $552 thousand $0, and $0, respectively, for liquidated damages under the service and warranty agreement, which were recorded as a reduction to property, plant and equipment, net on the consolidated balance sheets and to capital expenditures included within cash flows from investing activities. Effective January 1, 2024, Mesquite Sky entered into a settlement agreement with Siemens for liquidated damages under the service and warranty agreement totaling $5.9 million for the period from July 11, 2022 through July 10, 2023 and for anticipated damages for the period from January 1, 2024 through July 10, 2024. (e) Tax Abatement Agreement Mesquite Sky is party to an amended Tax Abatement Agreement with Callahan County, Texas, in which Mesquite Sky is exempted from 100% of the property taxes on 165 MWs of certified appraised eligible property for ten years beginning on January 1, 2022 through December 31, 2031. The remaining MWs are not subject to the abatement and, therefore, subject to the normal property tax rates. As consideration for the abatement, Mesquite Sky is obligated to make ten annual LIGHTHOUSE RENEWABLE HOLDCO 2 LLC AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2023, 2022 and 2021 14


 
payments in lieu of taxes to Callahan County of two thousand dollars per MW, with the first payment due on October 1, 2022 and the remaining nine payments due annually thereafter on October 1. In addition, Mesquite Sky agreed to make improvements to the eligible property as defined in the agreement, which were completed as of COD. Mesquite Sky paid $330 thousand for each of the years ended December 31, 2023 and 2022, which was included in cost of operations in the consolidated statements of operations. Mesquite Star Special Agreements (a) ISDA Master Agreement Mesquite Star Special and a third party are parties to an ISDA 2002 Master Agreement, or Star Hedge Agreement, dated as of May 3, 2019, as amended. Under the Star Hedge Agreement, the Company is party to a 12-year agreement to sell power to a counterparty at a fixed price, which is utilized to manage the risk of fluctuations in market prices on sales of electricity. The energy-related commodity contract is accounted for as a derivative financial instrument as described in note 2(k) Derivative Financial Instruments. The Star Hedge Agreement contains provisions providing the counterparty a lien on specific assets as collateral. Also see note 4, Accounting for Derivative Instruments and Hedging Activities, for further information. Tracking Account The energy-related commodity contract contains provisions that allows for Mesquite Star Special to receive additional money from the counterparty when the price of electricity at the interconnection point of the Mesquite Star Special Facility is less than the price of electricity at the hub where Mesquite Star Special is obligated to sell electricity (adjusted for actual generation delivered versus the quantity purchased at the hub). This mismatch is accumulated in a tracking account, which represents a liability that is due to the counterparty at the conclusion of the contract. Mismatch amounts received by Mesquite Star Special increase the tracking account liability owed by Mesquite Star Special up to the maximum liability of $10.5 million. When the calculated mismatch amount results in Mesquite Star Special making a payment to the hedge counterparty, the amount may reduce the tracking account balance but only until the tracking account balance is paid in full. The balance in the tracking account accrues interest at Adjusted Secured Overnight Financing Rate, or Adjusted SOFR, plus an adjustment of 0.26161% and an applicable margin of 2.5%. The interest incurred is recorded within interest expense in the consolidated statements of operations. Upon termination of the energy-related commodity contract on May 31, 2032, the tracking account balance will be settled between the Mesquite Star Special and the counterparty. If the tracking account balance is less than zero, then the Mesquite Star Special shall pay the counterparty the absolute value of the tracking account balance. As of December 31, 2023 the Mesquite Star Special recorded a liability for the tracking account balance of $10.5 million.

(2) Summary of Significant Accounting Policies (a) Basis of Presentation and Principles of Consolidation The Company’s consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States, or U.S. GAAP. The Accounting Standards Codification, or ASC, established by the Financial Accounting Standards Board, or FASB, is the source of authoritative U.S. GAAP to be applied by nongovernmental entities. The consolidated financial statements include the Company’s accounts and operations and those of its subsidiaries in which the Company has a controlling financial interest. All significant intercompany transactions and balances have been eliminated in the consolidated financial statements. The usual condition for a controlling financial interest is ownership of the majority of the voting interests of an entity. However, a controlling financial interest may also exist through arrangements that do not involve controlling voting interests. As such, the Company applies the guidance of ASC 810, Consolidations, to determine when an entity that is not controlled through its voting interests should be consolidated. (b) Restricted Cash The following table provides a reconciliation of cash and restricted cash reported within the consolidated balance sheets that sum to the total of the same such amounts shown in the consolidated statements of cash flows as of December 31, 2023 and 2022 (in thousands): 2023 2022 Cash $ 3,551 $ 4,981 Restricted cash 33,683 8,138 Cash and restricted cash shown in the consolidated statements of cash flows $ 37,234 $ 13,119 Restricted cash for 2023 primarily consists of funds held in reserves for performance obligations related to the completion of construction for the TSN1 Facility and the Mesquite Sky Facility, of which $20.0 million has been released during the first quarter of 2024. In addition, 2023 includes funds received from Siemens in accordance with the settlement agreement described in Mesquite Star Special note 1(c), Siemens Gamesa Renewable Energy, Inc. Service and Warranty Agreement. Restricted cash for 2022 primarily consisted of funds held in reserves for performance obligations related to the completion of construction for the Mesquite Sky Facility. (c) Accounts Receivable – Trade Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The Company’s energy revenue related customers typically receive invoices monthly with payment due within 30 days. There was no allowance for credit losses as of December 31, 2023 and 2022. LIGHTHOUSE RENEWABLE HOLDCO 2 LLC AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2023, 2022 and 2021 19


 
(d) Property, Plant, and Equipment Property, plant, and equipment are stated at cost; however, impairment adjustments are recorded whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. Significant additions or improvements extending asset lives are capitalized as incurred, while repairs and maintenance that do not improve or extend the life of the respective asset are charged to expense as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. Certain assets and their related accumulated depreciation amounts are adjusted for asset retirements and disposals with the resulting gain or loss included in cost of operations in the consolidated statements of operations. See note 5, Property, Plant, and Equipment, for additional information. (e) Asset Impairments Long-lived assets that are held and used are reviewed for impairment whenever events or changes in circumstances indicate their carrying amounts may not be recoverable. Such reviews are performed in accordance with ASC 360, Property, Plant, and Equipment. An impairment loss is indicated if the total future estimated undiscounted cash flows expected from an asset are less than its carrying amount. An impairment charge is measured as the excess of an asset’s carrying amount over its fair value with the difference recorded in operating costs and expenses in the consolidated statements of operations. Fair values are determined by a variety of valuation methods, including third-party appraisals, sales prices of similar assets, and present value techniques. There were no indicators of impairment loss as of December 31, 2023, 2022 and 2021. (f) Debt Issuance Costs Debt issuance costs consist of legal fees and closing costs incurred by TSN1 in obtaining its financing. These costs are capitalized and amortized as interest expense using the effective interest method over the term of the related debt, and are presented on the consolidated balance sheets as a direct deduction from the carrying amount of the related debt. There was no amortization expense recorded for the year ended December 31, 2023. (g) Intangible Asset Intangible asset represents the fair value of a software license acquired. The Company recognizes specifically identifiable intangible assets when specific rights and contracts are acquired. The asset is amortized on a straight-line basis over the term of the VPPA through 2041. See note 6, Intangible Asset, for additional information. (h) Leases The Company accounts for its leases under ASC 842, Leases, or ASC 842. ASC 842 requires the establishment of a lease liability and related right-of-use asset for all leases with a term longer than 12 months. The Company evaluates each arrangement at inception to determine if it contains a lease. The Company has elected to apply the practical expedient to not separate lease and non-lease components of the leases. LIGHTHOUSE RENEWABLE HOLDCO 2 LLC AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2023, 2022 and 2021 20


 
The Company records its operating lease liabilities at the present value of the lease payments over the lease term at lease commencement date. Lease payments include fixed payment amounts, as well as variable rate payments based on an index initially measured at lease commencement date. Variable payments, including payments based on future performance and based on index changes, are recorded when the expense is probable. The Company determines the relevant lease term by evaluating whether renewal and termination options are reasonably certain to be exercised. The Company uses its incremental borrowing rate to calculate the present value of the lease payments, based on information available at the lease commencement date. All of the Company’s leases are operating leases. See note 12, Leases for information on the Company’s leases. (i) Income Taxes The Company is classified as a partnership for federal and state income tax purposes. Therefore, federal and most state income taxes are assessed at the partner level. The state of Texas, however, imposes a franchise tax (characterized as an income tax for U.S. GAAP purposes) to which the Company’s subsidiaries are subject. For the years ended December 31, 2023 and 2022 and the period from December 17, 2021 through December 31, 2021, the Company had no current income tax expense and has calculated deferred income tax (benefit) expense of $(1.7) million, $163 thousand and $871 thousand, respectively. The Company has determined that, based on a more-likely-than not evaluation of the tax positions taken, there are no material uncertain tax positions to be recognized as of December 31, 2023, 2022 and 2021 by the Company. (j) Revenue Recognition Virtual Power Purchase Agreements The Company accounts for energy revenue recognized under the VPPAs in accordance with ASC 606, Revenue from Contracts with Customers, or ASC 606. Revenue from the sale of bundled RECs under the VPPAs is recognized when the related energy is generated and simultaneously delivered to the market, even in cases where there is a certification lag, as it has been deemed to be perfunctory as this is the point in time in which the performance obligation is satisfied and control of the REC is transferred to the customer. In such cases, it is often unnecessary to allocate transaction price to multiple performance obligations. For the years ended December 31, 2023 and 2022 and the period from December 17, 2021 through December 31, 2021, Mesquite Sky incurred $295 thousand, $1.5 million, and $0, respectively, in availability damages to the offtakers under the VPPAs. For the year ended December 31, 2023, Mesquite Star Special incurred $96 thousand in availability damages to the offtakers under the VPPAs. Availability damages were recorded as a reduction to operating revenues in the consolidated statements of operations. Merchant Revenue The Company sells uncontracted electricity into the Electric Reliability Council of Texas, or ERCOT, real-time market. This merchant electric revenue is recognized when the electricity is produced by the facilities and simultaneously delivered to ERCOT. LIGHTHOUSE RENEWABLE HOLDCO 2 LLC AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2023, 2022 and 2021 21


 
Unbundled Renewable Energy Certificates/Credits, or RECs Effective March 16, 2022, Mesquite Sky entered into an agreement with a third party for the sale of RECs generated from 2022 through 2026. RECs are sold at a fixed price up to a stated contract quantity as defined in the agreement. Revenue from the sale of the RECs is recognized when the related energy is generated and simultaneously delivered to the market, even in cases where there is a certification lag, as it has been deemed to be perfunctory as this is the point in time in which the performance obligation is satisfied and control of the REC is transferred to the customer. Termination of the agreement may be allowed under specific circumstances, such as under an event of default. Contract Amortization Included in other non-current assets on the consolidated balance sheets are capitalized costs to acquire the VPPAs at the Mesquite Sky Facility. The costs are amortized as a reduction to operating revenues on a straight-line basis over the terms of the VPPAs, through 2036. Derivative Revenue The Company accounts for the energy-related commodity contracts related to Mesquite Sky and Mesquite Star Special as derivative instruments in accordance with ASC 815, Derivatives and Hedging, or ASC 815, as described in note 2(k) below. As a result, the Company must mark the contracts to fair value each reporting period. The change in fair value of the energy-related commodity contracts is recorded to operating revenues. Also see note 4, Accounting for Derivative Instruments and Hedging Activities for further information on the energy-related commodity contracts. Disaggregated Revenues The following table summarizes the Company’s disaggregation of revenue from contracts with customers for the years ended December 31, 2023 and 2022 and the period from December 17, 2021 through December 31, 2021 (in thousands): 2023 2022 2021 Energy revenues (a) (b) $ 4,038 $ (658) $ 27 REC revenues 1,075 1,364 — Other revenues (177) (23) — Contract amortization (154) (154) (6) Mark-to-market for derivative instruments (c) (6,217) (34,425) 1,199 Total operating revenues $ (1,435) $ (33,896) $ 1,220 (a) As of December 31, 2023 and 2022, $391 thousand and $463 thousand, respectively, is included in accounts payable - trade related to amounts due to the counterparties of the VPPAs and the qualified scheduling entity. (b) Includes settlement fees of $324 thousand and $3.1 million in 2023 and 2022, respectively, as described in note 1, Nature of Business. (c) Represents the (losses) gains from the change in fair value of the derivative instrument in accordance with ASC 815. LIGHTHOUSE RENEWABLE HOLDCO 2 LLC AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2023, 2022 and 2021 22


 
Contract Balances The following table reflects the contract assets in the Company’s consolidated balance sheets as of December 31, 2023 and 2022 (in thousands): 2023 2022 Accounts receivable - contracts with customers $ 848 $ 274 Accounts receivable - derivative instruments 112 803 Accounts receivable - other (a) 8,762 — Total accounts receivable - trade $ 9,722 $ 1,077 (a) Included in 2023 are insurance proceeds, as described in note 5, Property, Plant, and Equipment, and liquidated damages due from Waaree, as described in note 1, TSN1 Agreements (d) Equipment Supply Agreement. (k) Derivative Financial Instruments The Company accounts for derivative financial instruments in accordance with ASC 815, which requires the Company to recognize all derivative instruments on the balance sheet as either assets or liabilities and to measure them at fair value each reporting period unless they qualify for a normal purchase normal sale exception. The Company is party to long-term energy-related commodity contracts which are not designated as cash flow or fair value hedges. Settlements and changes in the fair value of the energy-related commodity contracts are recognized in operating revenues. The Company uses interest rate swaps to manage its interest rate exposure on long-term debt, which are not designated as cash flow hedges. Changes in the fair value of non-hedge derivatives are immediately recognized in earnings. Cash flows from derivatives not designated as cash flow hedges are classified as operating activities in the consolidated statements of cash flows. See note 4, Accounting for Derivative Instruments and Hedging Activities, for more information. (l) Risks and Uncertainties Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of accounts receivable – trade and derivative financial instruments. Accounts receivable are concentrated with commercial customers and a private university. The concentration of sales to a small group of customers may impact the Company’s overall exposure to credit risk, either positively or negatively, in that the customers may be similarly affected by changes in economic, industry, or other conditions. However, the Company believes that the credit risk posed by such concentrations is offset by the creditworthiness of its customer base. The Company is also exposed to credit losses in the event of noncompliance by counterparties to its derivative financial instruments. Risks associated with the Company’s operations include the performance of the facilities below expected levels of efficiency and output, shutdowns due to the breakdown or failure of equipment, which could be further impacted by the inability to obtain replacement parts, or catastrophic events such as extreme weather, fires, earthquakes, floods, explosions, pandemics, or other similar occurrences affecting a power generation facility or its energy purchasers. LIGHTHOUSE RENEWABLE HOLDCO 2 LLC AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2023, 2022 and 2021 23


 
Should a generation facility fail to perform at the required levels, or other unplanned disruptions occur, the facility may be forced to fulfill an underlying contractual obligation by purchasing electricity at higher prices. In addition, the Company’s facilities may be exposed, based on specific contractual terms, to a locational basis risk resulting from a difference in the price received for generation sold at the location where the power is generated and the price paid for generation purchased at the contracted delivery point, which could lead to potential lower revenues in circumstances where the price received is lower than the price that is paid. (m) Fair Value of Financial Instruments The Company accounts for the fair value of financial instruments in accordance with ASC 820, Fair Value Measurement, or ASC 820. The Company does not hold or issue financial instruments for trading purposes. ASC 820 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels as follows: • Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access as of the measurement date. • Level 2 – Inputs other than quoted prices included within Level 1 that are directly observable for the asset or liability or indirectly observable through corroboration with observable market data. • Level 3 – Unobservable inputs for the asset or liability only used when there is little, if any, market activity for the asset or liability at the measurement date. In accordance with ASC 820, the Company determines the level in the fair value hierarchy within which each fair value measurement in its entirety falls, based on the lowest level input that is significant to the fair value measurement in its entirety. For cash, restricted cash, accounts receivable – trade, notes payable, notes payable – affiliate, accounts payable – trade, accounts payable – affiliate, and accrued and other current liabilities, the carrying amounts approximate fair value because of the short-term maturity of those instruments and are classified as Level 1 within the fair value hierarchy. LIGHTHOUSE RENEWABLE HOLDCO 2 LLC AND SUBSIDIARIES Notes to Consolidated Financial Statements December 31, 2023, 2022 and 2021 24


 
The carrying amount and estimated fair value of the Company’s recorded financial instrument not carried at fair market value or that does not approximate fair value as of December 31, 2023 and 2022 is as follows (in thousands): 2023 2022 Carrying Amount Fair Value Carrying Amount Fair Value Long-term debt, including current portion (a) $ 101,696 $ 100,878 $ — $ — (a) Excludes net debt issuance costs, as shown in note 7, Long-Term Debt. The fair value of long-term debt is based on expected future cash flows discounted at current interest rates for similar instruments with equivalent credit quality and is classified as Level 3 within the fair value hierarchy. Derivative instruments, consisting of interest rate swaps, are recorded at fair value on the Company’s consolidated balance sheets on a recurring basis and are classified as Level 2 within the fair value hierarchy as the fair value is determined using an income approach, which uses readily observable inputs, such as forward interest rates and contractual terms to estimate fair value. Derivative instruments, consisting of energy-related commodity contracts, are recorded at fair value on the Company’s consolidated balance sheets on a recurring basis and are classified as Level 3 within the fair value hierarchy. Management uses quoted observable forward prices, and to the extent that quoted observable forward prices are not available, the quoted prices reflect the average of the forward prices from the prior year, adjusted for inflation. The Company’s energy-related commodity contracts are executed in illiquid markets. The significant unobservable inputs used in developing fair value include illiquid power tenors and location pricing, which is derived by extrapolating pricing as a basis to liquid locations. The tenor pricing and basis spread are based on observable market data when available or derived from historic prices and forward market prices from similar observable markets when not available. The fair value of each contract is discounted using a risk-free interest rate. In addition, the Company applies a credit reserve to reflect credit risk, which for interest rate swaps is calculated using the bilateral method based on published default probabilities. For commodities, to the extent that the Company’s net exposure under a specific master agreement is an asset, the Company uses the counterparty’s default swap rate. If the net exposure under a specific master agreement is a liability, the Company uses a proxy of its own default swap rate. For interest rate swaps and commodities, the credit reserve is added to the discounted fair value to reflect the exit price that a market participant would be willing to receive to assume the Company’s liabilities or that a market participant would be willing to pay for the Company’s assets. As of December 31, 2023, the non-performance reserves were an $10.9 million gain recorded to total operating revenues in the consolidated statements of operations.

(n) Commitments and Contingencies In the normal course of business, the Company is subject to various claims and litigation. Management of the Company expects that these various litigation items will not have a material adverse effect on the results of operations, cash flows, or financial position of the Company. (o) Asset Retirement Obligations The Company accounts for its asset retirement obligations, or AROs, in accordance with ASC 410-20, Asset Retirement Obligations, or ASC 410-20. Retirement obligations associated with long-lived assets included within the scope of ASC 410-20 are those for which a legal obligation exists under enacted laws, statutes, and written or oral contracts, including obligations arising under the doctrine of promissory estoppel, and for which the timing and/or method of settlement may be conditional on a future event. ASC 410-20 requires an entity to recognize the fair value of a liability for an ARO in the period in which it is incurred and a reasonable estimate of fair value can be made. Upon initial recognition of a liability for an ARO, other than when an ARO is assumed in an acquisition of the related long-lived asset, the Company capitalizes the asset retirement cost by increasing the carrying amount of the related long-lived asset by the same amount. Over time, the liability is accreted to its future value, while the capitalized cost is depreciated over the useful life of the related asset. See note 9, Asset Retirement Obligations, for further information. (p) Tax Equity Arrangements Certain portions of the Company’s noncontrolling interests in subsidiaries represent third-party interests in the net assets under certain tax equity arrangements, which are consolidated by the Company. The Company has determined that the provisions in the contractual agreements of these structures represent substantive profit sharing arrangements. Further, the Company has determined that the appropriate methodology for calculating the noncontrolling interest that reflects the substantive profit sharing arrangements is a balance sheet approach utilizing the hypothetical liquidation at book value, or HLBV, method. Under the HLBV method, the amounts reported as noncontrolling interests represent the amounts the tax equity investor would hypothetically receive at each balance sheet date under the liquidation provisions of the contractual agreements, assuming the net assets of the funding structures were liquidated at their recorded amounts determined in accordance with U.S. GAAP. The tax equity investor’s interest in the results of operations of the funding structures are determined as the difference in noncontrolling interests at the start and end of each reporting period, after taking into account any capital transactions between the structures and the funds’ investors. The calculations utilized to apply the HLBV method include estimated calculations of taxable income or losses for each reporting period. In addition, in certain circumstances, the Company and its partners in the tax equity arrangements agree that certain tax benefits are to be utilized outside of the tax equity arrangements, which may result in differences in the amount an investor would hypothetically receive at the initial balance sheet date calculated strictly in accordance with related contractual agreements. These differences are recognized in the consolidated statements of operations using a systematic and rational method over the period during which the investor is expected to achieve its target return.

(r) Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period, including the fair value of the energy-related commodity contract derivatives. Actual results may differ from those estimates. (s) Reclassifications Certain prior year amounts have been reclassified for comparative purposes.
