The Company is primarily engaged in the geothermal and recovered energy business and primarily designs, develops, builds, sells, owns and operates clean, environmentally friendly geothermal and recovered energy-based power plants, usually using equipment that it designs and manufactures. The Company owns and operates geothermal and recovered energy-based power plants in various countries, including the United States, Kenya, Guatemala, Guadeloupe and Honduras. The Company’s equipment manufacturing operations are primarily located in Israel. Additionally, the Company owns and operates independent storage facilities in the United States providing energy storage and related services. Most of the Company’s domestic power plant facilities are Qualifying Facilities under the PURPA. The Power Purchase Agreements (“PPAs”) for certain of such facilities are dependent upon their maintaining Qualifying Facility status.

The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the accounts of the Company and of all majority-owned subsidiaries in which the Company exercises control over operating and financial policies, and variable interest entities in which the Company has an interest and is the primary beneficiary. Intercompany accounts and transactions have been eliminated in consolidation.

Investments in less-than-majority-owned entities or other entities in which the Company exercises significant influence over operating and financial policies are accounted for using the equity method of accounting or consolidated if they are a variable interest entity in which the Company has an interest and is the primary beneficiary. Under the equity method, original investments are recorded at cost and adjusted by the Company’s share of undistributed earnings or losses of such companies. The Company’s earnings or losses in investments accounted for under the equity method have been reflected as “equity in earnings (losses) of investees, net” on the Company’s consolidated statements of operations and comprehensive income (loss).

The preparation of 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 the disclosure of contingent assets and liabilities at the dates of such financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. The most significant estimates with regard to the Company’s consolidated financial statements relate to the useful lives of property, plant and equipment, impairment of goodwill and long-lived assets, including intangible assets, revenue recognition of product sales using the percentage of completion method, asset retirement obligations, and the provision for income taxes.

Under the terms of certain long-term debt agreements, the Company is required to maintain certain debt service reserves, including principal and interest, cash collateral and operating fund accounts, including for future wells drilling, which have been classified as restricted cash and cash equivalents. Funds that will be used to satisfy obligations due during the next 12 months are classified as current restricted cash and cash equivalents, with the remainder classified as non-current restricted cash and cash equivalents, if applicable. Such amounts are invested primarily in money market accounts and commercial paper with a minimum investment grade of “A”.

The Company places its temporary cash investments with high credit quality financial institutions located in the U.S. and in foreign countries. At December 31, 2024 and 2023, the Company had deposits totaling $31.2 million and $43.2 million, respectively, in ten United States financial institutions that were federally insured up to $250,000 per account. At December 31, 2024 and 2023, the Company’s deposits in foreign countries of approximately $73.9 million and $57.5 million, respectively, were not insured.

At December 31, 2024 and 2023, accounts receivable related to operations in foreign countries amounted to approximately $105.2 million and $152.2 million, respectively. At December 31, 2024 and 2023, accounts receivable from the Company’s major customers (see Note 17) amounted to approximately 57% and 57%, respectively, of the Company’s accounts receivable. The aggregate amount of notes receivable exceeding 10% of total receivables for the year ended December 31, 2024 and 2023 is $99.7 million and $161.0 million, respectively.

The Company has historically been able to collect substantially all of its receivable balances. As of December 31, 2024, the amount overdue from KPLC in Kenya was $38.3 million of which $20.0 million was paid in January and February of 2025. The Company believes it will be able to collect all past due amounts in Kenya. This belief is supported by the fact that in addition to KPLC's obligations under its power purchase agreement, the Company holds a support letter from the Government of Kenya that covers certain cases of KPLC non-payment (such as non-payments that are caused by government actions and/or political events).

Property, plant and equipment are stated at cost, (except when acquired as part of a business combination, as further described under Note 2 to the consolidated financial statements), net of accumulated depreciation. All costs associated with the acquisition, development and construction of power plants operated by the Company are capitalized. Major improvements are capitalized and repairs and maintenance (including major maintenance) costs are expensed. Power plants operated by the Company, which include geothermal wells and exploration and resource development costs, are depreciated using the straight-line method over their estimated useful lives, which range from 15 to 30 years. The other assets are depreciated using the straight-line method over the following estimated useful lives of the assets:

The Company capitalizes interest costs as part of constructing power plant facilities. Such capitalized interest is recorded as part of the asset to which it relates and is amortized over the asset’s estimated useful life. Capitalized interest costs amounted to $14.7 million, $17.3 million, and $18.7 million for the years ended December 31, 2024, 2023 and 2022, respectively.

The Company capitalizes costs incurred in connection with the exploration and development of geothermal resources once it acquires land rights to the potential geothermal resource. Prior to acquiring land rights, the Company makes an initial assessment that an economically feasible geothermal reservoir is probable on that land. The Company determines the economic feasibility of potential geothermal resources internally, with all available data and external assessments vetted through the exploration department and occasionally using outside service providers. Costs associated with the initial assessment are expensed and included in cost of electricity revenues in the consolidated statements of operations and comprehensive income (loss). Such costs were immaterial during the years ended December 31, 2024, 2023 and 2022. It normally takes two to three years from the time active exploration of a particular geothermal resource begins to the time a production well is in operation, assuming the resource is commercially viable. However, in certain sites the process may take longer due to permitting delays, transmission constraints or any other commercial milestones that are required to be reached in order to pursue the development process.

In most cases, the Company obtains the right to conduct the geothermal development and operations on land owned by the Bureau of Land Management ("BLM"), various states or with private parties. The land lease payments made during the exploration, development and construction phase are accounted under lease accounting as further described under the caption Leases below and reflected as expenses under “Electricity cost of revenues” in the consolidated statements of operations and comprehensive income (loss). Upon commencement of power generation on the leased land, the Company begins to pay the lessor’s long-term royalty payments based on the utilization of the geothermal resources as defined in the respective agreements. Such payments are expensed when the related revenues are earned and included in “Electricity cost of revenues” in the consolidated statements of operations and comprehensive income (loss).

Following the acquisition of land rights to the potential geothermal resource, the Company conducts further studies and surveys, including water and soil analyses, among others, and augments its database with the results of these studies. The Company then initiates a suite of geophysical surveys to assess the resource and determine drilling locations. If the results of these activities support the initial assessment of the feasibility of the geothermal resource, the Company then proceeds to exploratory drilling and other related activities which may include drilling of temperature gradient holes, drilling of slim holes, building access roads to drilling locations, drilling full size production and/or injection wells and flow tests. If the slim hole supports a conclusion that the geothermal resource will support a commercially viable power plant, it may be converted to a full-size commercial well, used either for extraction or re-injection of geothermal fluids, or be used as an observation well to monitor and define the geothermal resource. Costs associated with these activities and other directly attributable costs, including interest once physical exploration activities begin, and permitting costs are capitalized and included in “Construction-in-process”. If the Company concludes that a geothermal resource will not support commercial operations, capitalized costs are expensed in the period such determination is made.

When deciding whether to continue holding lease rights and/or to pursue exploration activity, the Company diligently prioritizes prospective investments, taking into account resource and probability assessments in order to make informed decisions about whether a particular project will support commercial operation. During the years ended December 31, 2024, 2023 and 2022, the Company recorded $3.9 million, $3.7 million, and $0.8 million of unsuccessful exploration and storage activities, respectively, that the

The Company records the fair value of a legal liability for an asset retirement obligation in the period in which it is incurred. The Company’s legal liabilities include plugging wells and post-closure costs of power producing and storage sites. When a new liability for asset retirement obligations is recorded, the Company capitalizes the costs of the liability by increasing the carrying amount of the related long-lived asset. The liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. The Company periodically reassesses the assumptions used to estimate the expected cash flows required to settle the asset retirement obligation, including changes in estimated probabilities, amounts, and timing of the settlement of the asset retirement obligation, as well as changes in the legal requirements of an obligation and revises the previously recorded asset retirement obligation accordingly. At retirement, the obligation is settled for its recorded amount at a gain or loss.

Deferred financing costs are presented as a direct deduction from the carrying value of the associated debt liability or under "Deposits and other" if associated with lines of credit. Such deferred costs are amortized over the term of the related obligation using the effective interest method or ratably, as applicable. Amortization of deferred financing costs is presented as interest expense in the consolidated statements of operations and comprehensive income (loss). Amortization expense for the years ended December 31, 2024, 2023 and 2022 amounted to $5.9 million, $5.9 million, and $4.2 million, respectively. During the years ended December 31, 2024, 2023 and 2022, no material amounts were written-off as a result of extinguishment of liabilities.

Goodwill represents the excess of the fair value of consideration transferred in the business combination transactions over the fair value of tangible and intangible assets acquired, net of the fair value of liabilities assumed and the fair value of any noncontrolling interest in the acquisitions. Goodwill is not amortized but rather subject to a periodic impairment testing on an annual basis, which the Company performs on December 31 of each year, or if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying amount. Additionally, it is permitted to first assess qualitative factors to determine whether a quantitative goodwill impairment test is necessary. Further testing is only required if the entity determines, based on the qualitative assessment, that it is more likely than not that a reporting unit’s fair value is less than its carrying amount. Otherwise, no further impairment testing is required. An entity has the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to the quantitative goodwill impairment test. This would not preclude the entity from performing the qualitative assessment in any subsequent period. The quantitative assessment compares the fair value of the reporting unit to its carrying value, including goodwill. Under ASU 2017-04, Intangibles – Goodwill and Other (Topic 350), an entity should recognize an impairment charge for the amount by which the carrying amount of the reporting unit exceeds its fair value. However, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. For further information relating to goodwill see Note 9 - Intangible Assets and Goodwill to the consolidated financial statements.

Intangible assets consist of allocated acquisition costs of PPAs, which are amortized using the straight-line method over the 4 to 17-year terms of the agreements (see Note 9) as well as acquisition costs allocation related to the Company's Energy Storage segment activities that are amortized over a period of between approximately 6 and 19 years. Intangible assets are tested for recoverability whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. In case there are no such events or change in circumstances, there is no need to perform an impairment testing. The recoverability is tested by comparing the net carrying value of the intangible assets to the undiscounted net cash flows to be generated from the use and eventual disposition of these assets. If the carrying amount of a long-lived asset (or asset group) is not recoverable, the fair value of the asset (asset group) is measured and if the carrying amount exceeds the fair value, an impairment loss is recognized.

The Company evaluates long-lived assets, such as property, plant and equipment and construction-in-process for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Factors which could trigger an impairment include, among others, significant underperformance relative to historical or projected future operating results, significant changes in the Company’s use of assets or its overall business strategy, negative industry or economic trends, a determination that an exploration project will not support commercial operations, a determination that a suspended project is not likely to be completed, a significant increase in costs necessary to complete a project, legal factors relating to its business or when it concludes that it is more likely than not that an asset will be disposed of or sold.

The Company tests its operating plants that are operated together as a complex for impairment at the complex level because the cash flows of such plants result from significant shared operating activities. For example, the operating power plants in a complex are managed under a combined operation management generally with one central control room that controls all of the power plants in a complex and one maintenance group that services all of the power plants in a complex. As a result, the cash flows from individual plants within a complex are not largely independent of the cash flows of other plants within the complex. The Company tests for impairment of its operating plants which are not operated as a complex as well as its projects under exploration, development or construction that are not part of an existing complex at the plant or project level. To the extent an operating plant becomes part of a complex, the Company will test for impairment at the complex level.

Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated future net undiscounted cash flows expected to be generated by the asset. The significant assumptions that the Company uses in estimating its undiscounted future cash flows include: (i) projected generating capacity of the complex or power plant and rates to be received under the respective PPAs and expected market rates thereafter and (ii) projected operating expenses of the relevant complex or power plant. Estimates of future cash flows used to test recoverability of a long-lived asset under development also include cash flows associated with all future expenditures necessary to develop the asset.

If the assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds their fair value. Management believes that as of December 31, 2024, no impairment exists for long-lived assets, however, estimates as to the recoverability of such assets may change based on revised circumstances. If actual cash flows differ significantly from the Company’s current estimates, a material impairment charge may be required in the future.

Derivative instruments (including certain derivative instruments embedded in other contracts) are measured at their fair value and recorded as either assets or liabilities unless exempted from derivative treatment as a normal purchase and sale. Changes in the fair value of derivatives not designated as hedging instruments are recognized in earnings. Changes in the fair value of derivatives designated as cash flow hedging instruments are initially recorded in “Other comprehensive income (loss)” and a corresponding amount is reclassified out of “Accumulated other comprehensive income (loss)” into earnings to offset the impact of the underlying hedge transaction when it affects earnings under the same line item in the consolidated statements of operations and comprehensive income.

The U.S. dollar is the functional currency for all of the Company’s consolidated operations and those of its equity affiliates except the Guadeloupe power plant and the Company's operations in New Zealand. For those U.S. dollar functional currency entities, all gains and losses from currency translations are included under “Derivatives and foreign currency transaction gains (losses)” in the consolidated statements of operations and comprehensive income (loss). The Euro and New Zealand Dollar are the functional currencies of the Company's operations in Guadeloupe and New Zealand, respectively, and thus the impact from currency translation adjustments related to those locations is included as currency translation adjustments in “Accumulated other comprehensive income” in the consolidated statements of equity and in comprehensive income. The accumulated currency translation adjustments amounted to a debit of $9.3 million and a debit of $2.3 million, as of December 31, 2024 and 2023, respectively.

Comprehensive income includes net income plus other comprehensive income (loss), which for the Company consists primarily of changes in foreign currency translation adjustments, changes in unrealized gains or losses in respect of the Company’s share in derivatives instruments of an unconsolidated investment that qualifies as a cash flow hedge, and changes in respect of derivative instruments designated as a cash flow hedge. The changes in foreign currency translation adjustments included under other comprehensive income (loss) during the years ended December 31, 2024, 2023 and 2022 amounted to $(8.2) million, $1.3 million, and $(2.5) million, respectively. The changes in the Company’s share in derivative instruments of an unconsolidated investment, and gains or losses in respect of derivative instruments designated as a cash flow hedge are disclosed under Note 5 – Investment in unconsolidated companies, and Note 7 - Fair value of financial instruments, respectively, to the consolidated financial statements.

payments or both energy and capacity payments through their respective terms which expire in varying periods from 2025 to 2051. Generally, capacity payments are calculated based on the amount of time that the power plants are available to generate electricity. The energy payments are calculated based on the amount of electrical energy delivered at a designated delivery point. The price terms are customary in the industry and include, among others, a fixed price, SRAC (the incremental cost that the power purchaser avoids by not having to generate such electrical energy itself or purchase it from others), and a fixed price with an escalation clause that includes the value for environmental attributes, known as renewable energy credits. Certain of the PPAs provide for bonus payments in the event that the Company is able to exceed certain target levels and potential payments by the Company if it fails to meet minimum target levels. The Company has PPAs that give the power purchaser or its designee a right of first refusal or a right of first offer to acquire the geothermal power plants at fair market value as negotiated between the parties. One of the Company’s subsidiaries in Guatemala sells power at an agreed upon price subject to terms of a “take or pay” PPA.

Pursuant to the terms of certain of the PPAs, the Company may be required to make payments to the relevant power purchaser under certain conditions, such as shortfall in delivery of renewable energy and energy credits, and not meeting certain performance threshold requirements, as defined in the relevant PPA. The amount of payment required is dependent upon the level of shortfall in delivery or performance requirements and is recorded in the period the shortfall occurs. In addition, if the Company does not meet certain minimum performance requirements, the capacity of the power plant may be permanently reduced.

Revenues from contracts with customers are recognized in connection with the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Specifically, the Company is required to apply each of the following steps: (1) identify the contract(s) with the customer; (2) identify the performance obligations in the contracts; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the entity satisfies a performance obligation.

Revenues related to the sale of electricity from geothermal and recovered energy-based power plants and capacity payments are recorded based upon output delivered and capacity provided at rates specified under relevant contract terms. The Company assesses whether PPAs entered into, modified, or acquired in business combinations contain a lease element requiring lease accounting. Revenue from such PPAs are accounted for in electricity revenues. In the Electricity segment, revenues for all but thirteen power plants are accounted as operating leases, and therefore equipment related to geothermal and recovered energy generation power plants as described in Note 8 is considered held for leasing. For power plants in the scope of ASC 606, Revenue from Contracts with Customers (“ASC 606”), the Company identified electricity as a separate performance obligation. Performance obligations identified were evaluated and determined to be satisfied over time and qualified for the invoicing practical expedient since the invoiced amounts reasonably represents the value to customers of performance obligations fulfilled to date. The transaction price is determined based on the price per actual mega-watt output or available capacity as agreed to in the respective PPA. Customers are generally billed on a monthly basis and payment is typically due within 30 to 60 days after the issuance of the invoice.

Revenues from engineering, operating services, and parts and product sales are recorded upon providing the service or delivery of the products and parts and when collectability is reasonably assured. Revenues from the supply and/or construction of geothermal and recovered energy-based power plant equipment and other equipment to third parties are recognized over time since control is transferred continuously to the Company's customers. The majority of the Company's contracts include a single performance obligation which is essentially the promise to transfer the individual goods or services that are not separately identifiable from other promises in the contracts and therefore deemed as not distinct. Performance obligations are satisfied over-time if the customer receives the benefits as the Company performs work, if the customer controls the asset as it is being constructed, or if the product being produced for the customer has no alternative use and the Company has a contractual right to payment. In the Company's Product segment, revenues are spread over a period of one to two years and are recognized over time based on the cost incurred to date in ratio to total estimated costs which represents the input method that best depicts the transfer of control over the performance obligation to the customer. Costs include direct material, labor, and indirect costs. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined.

In contracts for which the Company determines that control is not transferred continuously to the customer, the Company recognizes revenues at the point in time when the customer obtains control of the asset. Revenues for such contracts are recorded upon delivery and acceptance by the customer. This generally is the case for the sale of spare parts, generators or similar products.

Accounting for product contracts that are satisfied over time includes use of several estimates such as variable consideration related to bonuses and penalties and total estimated cost for completing the contract. The estimated amount of variable consideration will be included in the transaction price only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. These estimates are based on historical experience, anticipated performance and the Company's best judgment at the time.

The nature of the Company's product contracts give rise to several modifications or change requests by its customers. Substantially all of the modifications are treated as cumulative catch-ups to revenues since the additional goods are not distinct from those already provided. The Company includes the additional revenues related to the modifications in its transaction price when both parties to the contract approved the modification. As a significant change in one or more of these estimates could affect the profitability of the Company's contracts, the Company reviews and updates its contract-related estimates regularly. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, the Company recognizes the total loss in the period in which it is identified.

Battery energy storage systems as a service, and related services revenues are recorded based on energy management of load curtailment capacity delivered or service provided at rates specified under the relevant contract terms. The Company determined that such revenues are in the scope of ASC 606, and identified energy management services as a separate performance obligation. Performance obligations are satisfied once the Company provides verification to the electric power grid operator or utility of its ability to meet the committed capacity, the power curtailment requirements or the ancillary services and thus entitled to cash proceeds. Such verification may be provided by the Company bi-weekly, monthly or under any other frequency as set by the related program and are typically followed by a payment shortly after. Performance obligations identified were evaluated and determined to be satisfied over time and qualified for the invoicing practical expedient since the amounts included in the verification document reasonably represent the value of performance obligations fulfilled to date. The transaction price is determined based on mechanisms specified in the contract with the customer.

Contract assets related to the Company's Product segment reflect revenues recognized and performance obligations satisfied in advance of customer billing. Contract liabilities related to the Company's Product segment reflect customer billing in advance of the satisfaction of performance under the contract. The Company receives payments from customers based on the terms established in the contracts. Total contract assets and contract liabilities as of December 31, 2024 and 2023 are as follows:

(*) Contract assets and contract liabilities are presented as "Costs and estimated earnings in excess of billings on uncompleted contracts", and "Billings in excess of costs and estimated earnings on uncompleted contracts", respectively, on the consolidated balance sheets. The contract liabilities balance at the beginning of the year was substantially recognized as product revenues during the year ended December 31, 2024 as a result of performance obligations that were satisfied. Additionally, as of December 31, 2024, long-term costs and estimated earnings in excess of billings on uncompleted contracts related to the Dominica project in the amount of $26.0 million is included under “Deposits and other” in the consolidated balance sheets, and not under the contract assets and contract liabilities above, due its long-term nature.


	Years Ended December 31,
	2024				2023
	Contract assets		Contract liabilities		Contract assets		Contract liabilities
	(Dollars in thousands)
Recognition of contract liabilities as revenue as a result of performance obligations satisfied	$	—	$	12,698	$	—	$	6,883
Cash received in advance for which revenues have not yet recognized, net of expenditures made	—		(17,119)		—		(16,766)

The timing of revenue recognition, billings and cash collections result in accounts receivable, contract assets and contract liabilities on the consolidated balance sheet. In the Company's Products segment, amounts are billed as work progresses in accordance with agreed-upon contractual terms, or upon achievement of contractual milestones. Generally, billing occurs subsequent to the recognition of revenue, resulting in contract assets. However, the Company sometimes receives advances or deposits from its customers before revenue can be recognized, resulting in contract liabilities. These assets and liabilities are reported on the consolidated balance sheet on a contract-by-contract basis at the end of each reporting period. The timing of billing its customers and receiving advance payments vary from contract to contract. The majority of payments are received no later than the completion of the project and satisfaction of the Company's performance obligation.

The following schedule reconciles revenues accounted under lease accounting, and revenues accounted under ASC 606, Revenues from Contracts with Customers, to total consolidated revenues for the three years ended December 31, 2024, 2023 and 2022:


	Year Ended December 31,
	2024		2023		2022
	(Dollars in thousands)
Electricity and Storage revenues accounted under lease accounting	$	553,348	$	542,065	$	529,264

In December 2023, the Company entered into agreements with the Commonwealth of Dominica to build and operate a 10 MW binary geothermal power plant in the Caribbean country of Dominica. Under these agreements, the Company will construct the power plant, operate and sell its generated energy to Dominica Electricity Services Limited (presently the only electricity utility in the Commonwealth of Dominica) over a period of 25 years, at the end of which, ownership of the power plant will be transferred to the Government of the Commonwealth of Dominica. The Company accounted for this transaction under the guidance of ASC 853, Service Concession Arrangements (“ASC 853”), which directs a reporting entity to apply ASC 606, Revenue from Contracts with Customers.

Under the aforementioned accounting guidance, the Company identified the construction and the operation of the power plant as two distinct performance obligations, and accordingly allocated the total transaction price to these separate performance obligations in the arrangement, based on their estimated stand-alone selling price. The Company concluded that the performance obligations are satisfied over time. Additionally, starting the second quarter of 2024, in conjunction with the power plant start of construction, the Company started recognizing revenues relating to the construction performance obligation based on an input method using costs incurred to total costs expected in the project. Such revenues are included under Product revenues in the consolidated statements of operations and comprehensive income.

The Company performs an analysis of potential credit losses related to its financial instruments that are within the scope of ASU 2018-19, Codification Improvements to Topic 325, Financial Instruments – Credit Losses. Such instruments are primarily cash and cash equivalents, restricted cash and cash equivalents, receivables (excluding those accounted under lease accounting) and costs and estimated earnings in excess of billings on uncompleted contracts, based on class of financing receivables which share the same or similar risk characteristics such as customer type and geographic location, among others. The Company estimates the expected credit losses for each class of financing receivables by applying the related corporate default rate which corresponds to the credit rating of the specific customer or class of financing receivables. For trade receivables, the Company applied this methodology using aging schedules reflecting how long the receivables have been outstanding. The Company has also considered the existence of credit enhancement arrangements that may mitigate the credit risk of its financial receivables in estimating the applicable corporate default rate. The Company considered the current and expected future economic and market conditions related to inflation and rising interest rates and determined that the estimate of credit losses was not significantly impacted.

ASU 2016-02, Leases (Topic 842), defines a lease as a contract, or part of a contract, that conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Control over the use of the identified asset means that the customer has both (a) the right to obtain substantially all of the economic benefits from the use of the asset, and (b) the right to direct the use of the asset.

The Company is a lessee in operating lease transactions primarily consisting of land leases for its exploration and development activities in the Electricity segment. The Company is also a lessee in finance lease transactions related to its fleet vehicles in the U.S. Additionally, one of the Company's power plant assets which was included in the Terra-Gen business acquisition in 2021, is subject to a sale and leaseback transaction that is accounted as a "failed" sale and leaseback. Additionally, as further described above under Revenues and cost of revenues, the Company acts as a lessor in PPAs that are accounted under ASC 842, Leases.

In accordance with the lease standard, for agreements in which the Company is the lessee, the Company applies a unified accounting model by which it recognizes a right-of-use asset ("ROU") and a lease liability at the commencement date of the lease contract for all the leases in which the Company has a right to control identified assets for a specified period of time. The classification of the lease as a finance lease or an operating lease determines the subsequent accounting for the lease arrangement.

same amount of the liability, adjusted for any prepaid or accrued lease payments, plus initial direct costs incurred in respect of the lease. Since the interest rate implicit in the lease is not readily determinable, the incremental borrowing rate of the Company is used. The subsequent measurement depends on whether the lease is classified as a finance lease or an operating lease.

d.Subsequent measurement of operating leases: after lease commencement, the Company measures the lease liability at the present value of the remaining lease payments using the discount rate determined at lease commencement (as long as the discount rate has not been updated as a result of a reassessment event). The Company subsequently measures the ROU asset at the present value of the remaining lease payments, adjusted for the remaining balance of any lease incentives received, any cumulative prepaid or accrued rent if the lease payments are uneven throughout the lease term and any unamortized initial direct costs. Further, the Company recognizes lease expense on a straight-line basis over the lease term.

e.Subsequent measurement of finance leases: after lease commencement, the Company measures the lease liability by increasing the carrying amount to reflect interest on the lease liability and reducing the carrying amount to reflect lease payments made during the period. The Company determines the interest on the lease liability in each period during the lease term as the amount that produces a constant periodic discount rate on the remaining balance of the liability, taking into consideration the reassessment requirements. After lease commencement, the Company measures the ROU assets at cost less any accumulated amortization and any accumulated impairment losses, taking into consideration the reassessment requirements. The Company amortizes the ROU asset on a straight-line basis, unless another systematic basis better represents the pattern in which the Company expects to consume the ROU asset’s future economic benefits. The ROU asset is amortized over the shorter of the lease term or the useful life of the ROU asset. The amortization period related to the finance lease transactions on fleet vehicles is 4-5 years. The total periodic expense (the sum of interest and amortization expense) of a finance lease is typically higher in the early periods and lower in the later periods.

•Variable lease payments that depend on an index or a rate: on the commencement date, the lease payments may include variability and depend on an index or a rate (such as the Consumer Price Index or a market interest rate). The Company does not remeasure the lease liability for changes in future lease payments arising from changes in an index or rate unless the lease liability is remeasured for another reason. Therefore, after initial recognition, such variable lease payments are recognized in profit or loss as they are incurred.

At lease commencement, the Company as a lessor classifies leases as either finance or operating leases. Finance leases are further classified as a sales-type lease or as a direct financing lease, however, the Company has no such leases as a lessor. Under an operating lease, the Company recognizes the lease payment as income over the lease term, generally as earned or on a straight-line basis.

The Company generally provides a one to two year warranty against defects in workmanship and materials related to the sale of products for electricity generation. The Company considers the warranty to be an assurance type warranty since the warranty provides the customer the assurance that the product complies with agreed-upon specifications. Estimated future warranty obligations are included in operating expenses in the period in which the related revenue is recognized. Such charges are immaterial for the years ended December 31, 2024, 2023 and 2022.

The Company accounts for stock-based compensation using the fair value method whereby compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense over the requisite employee service period (generally the vesting period of the grant). The Company uses the Complex Lattice, Three-based Option Pricing model and the Monte Carlo Simulation to calculate the fair value of the stock-based compensation awards.

The Company has the following five tax monetization transactions: Tungsten, McGinness Hills 3, Steamboat Hills, CD4 and North Valley, as further described under Note 12 – Tax Monetization Transactions. The purpose of these transactions is to form tax partnerships, whereby investors provide cash in exchange for equity interests that provide the holder a right to the majority of tax benefits associated with a renewable energy project. The Company accounts for a portion of the proceeds from the transaction as debt under ASC 470. Given that a portion of these transactions is structured as a purchase of an equity interest the Company also classifies a portion as noncontrolling interest consistent with guidance in ASC 810. The portion recorded to noncontrolling interest is initially measured at the fair value of the discounted tax attributes and cash distributions which represents the partner's residual economic interest. The residual proceeds are recognized as the initial carrying value of the debt which is classified as a “Liability associated with the sale of tax benefits”. The Company applies the effective interest rate method to the liability associated with the tax monetization transaction component as described by ASC 835 and CON 7. The tax benefits and cash distributions realized by the partner each period are treated as the debt servicing amounts, with the tax benefit amounts giving rise to income attributable to the sale of tax benefits. The deferred transaction costs are capitalized and amortized using the effective interest method.

Income taxes are accounted for using the asset and liability approach, which requires the recognition of taxes payable or refundable for the current year and deferred tax assets and liabilities for the future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. The measurement of current and deferred tax assets and liabilities are based on provisions of the enacted tax law. The Company accounts for investment tax credits and production tax credits (except for production tax credits which are sold under tax monetization transactions, as described above) as a reduction to income taxes in the year in which the credit arises. The measurement of deferred tax assets is reduced, if necessary, by the amount of any tax benefits that, based on available evidence, are more likely than not expected to be realized. A valuation allowance has been established to offset the Company’s U.S. deferred tax assets. Tax benefits from uncertain tax positions are recognized only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. Interest and penalties assessed by taxing authorities on an underpayment of income taxes are included as a component of income tax provision in the consolidated statements of operations and comprehensive income.

Basic earnings per share attributable to the Company’s stockholders (“earnings per share”) is computed by dividing net income attributable to the Company’s stockholders by the weighted average number of shares of common stock outstanding for the period, net of treasury shares. The Company does not have any equity instruments that are dilutive, except for stock-based awards and convertible senior notes.

As per ASU 2020-06, the if-converted method is required for calculating any potential dilutive effect from convertible instruments. For the years ended December 31, 2024 and 2023, the average price of the Company's common stock did not exceed the per share conversion price of its convertible senior notes (the "Notes") of $90.27, and other requirements for the Notes to be

Redeemable noncontrolling interest is currently redeemable and relates to a certain noncontrolling shareholder in a subsidiary having an option to sell its equity interest to the Company. The carrying value of the redeemable noncontrolling interest balance as of December 31, 2024 and 2023 approximates the redemption price of such interests. Changes in the carrying amount of the Company's Redeemable noncontrolling interest were as follows:

During the years ended December 31, 2024, 2023 and 2022, the Company’s Board of Directors (the “Board”) declared, approved, and authorized the payment of cash dividends in the aggregate amount of $29.1 million ($0.48 per share), $28.4 million ($0.48 per share), and $27.1 million ($0.48 per share), respectively. Such dividends were paid in the years declared.

On March 14, 2023, the Company entered into an underwriting agreement with Goldman Sachs & Co. LLC, as the sole underwriter (the “Underwriter”), in connection with a public offering, pursuant to which the Company agreed to issue and sell 3,600,000 shares of common stock, par value $0.001 per share, and the Underwriter agreed to purchase these shares at a price of $82.60 per share. In addition, the Company granted the Underwriter a 30-day option to purchase up to an additional 540,000 shares of common stock at the same price per share, which was fully exercised by the Underwriters on April 3, 2023. The total net proceeds from the offering, including the option, were approximately $341.7 million, after deducting offering expenses.

In connection with the issuance of the Convertible Senior Notes as further described in Note 11 to the consolidated financial statements, the Company used approximately $18.0 million of the net proceeds from the issuance of these Convertible Senior Notes to repurchase 258,667 shares of its common stock in privately negotiated transactions at a price of $69.45 per share. The Company recorded this purchase of treasury stock as a reduction to its equity on the consolidated statements of equity in the second quarter of 2022.

On July 11, 2023, ORPD LLC ("ORPD"), a subsidiary of the Company in which Northleaf Geothermal Holdings, LLC ("Northleaf") and the Company hold 36.75% and 63.25% equity interest, respectively, sold OREG 1, OREG 2, OREG 3 ("OREGs") and the Don A. Campbell complex to Ormat Nevada Inc. ("ONI"), a fully owned subsidiary of the Company. The proceeds from the sale were partially used by ORPD to make a distribution to its shareholders in which Northleaf's share was $30.0 million. Following this purchase transaction with the noncontrolling interest, the Company fully owns the OREGs and the Don A. Campbell complex and ORPD remains the holder of the Puna geothermal power plant. The Company accounted for this transaction as an equity transaction.

On October 19, 2023, the Company entered into a framework agreement for participation in the issuance of commercial paper (the "Commercial Paper Agreement") with Barak Capital Underwriting Ltd. under which the Company allowed the participants to submit proposals for purchasing and to purchase the Company's commercial paper ("Commercial Paper") in accordance with the provisions of the Commercial Paper Agreement. On October 23, 2023, the Company completed the issuance of the Commercial Paper in the aggregate amount of $73.2 million, and subsequently on December 11, 2023, the Company issued an additional amount of $26.8 million, under the same terms. The Commercial Paper was issued for a period of 90 days and extends automatically for additional 90 days periods for up to five years, unless the Company notifies the participants otherwise or a notice of termination is provided by the participants in accordance with the provisions of the Commercial Paper Agreement. The Commercial Paper bears an annual interest of three months SOFR +1.1% which will be paid at the end of each ninety days period. As of December 31, 2024, the base rate was 4.6%.

Starting October 7, 2023, Israel has been engaged in a complex multifront war, fighting against large-scale, repeated attacks on civilians from Iran, Hamas in the Gaza Strip, Hezbollah in Lebanon, the Houthis in Yemen, militant terrorist groups in the West Bank and others. Although Israel has since agreed to ceasefires with each of Hamas and Hezbollah with respect to the conflicts in the Gaza Strip and Lebanon, these conflicts could re-escalate if the ceasefires are violated. Iran, which has launched missiles directly at civilian targets in Israel twice during the current conflict, and other proxy forces and terrorist organizations have threatened to escalate the fighting throughout Israel, including targeting major infrastructure facilities. Additionally, the Houthis launched repeated attacks on marine vessels in the Red Sea, an important maritime route for international trade.

The majority of the Company's senior management and its main Product segment production and manufacturing facilities are located in Israel approximately 26 miles from the border with the Gaza Strip, and the Company receives supplies for and ship products for its Product segment via the Port of Ashdod, which is also close to the Gaza Strip and its coastline. While these disruptions have caused an increase in insurance premium costs for shipments into and out of the seaport, as of the date of these consolidated financial statements, none of the Company's facilities or infrastructure have been damaged nor have its supply chains been significantly impacted since the war broke out. However, a prolonged war could result in further military reserve duty call-ups as well as irregularities to the Company's supply chain and to its ability to ship its products from Israel, which could disrupt the operations of the Company's Product segment and potentially delay some of its growth plans in the Electricity segment. Management continuously monitors the effect of the war on the Company's financial position and results of operations.

On August 1, 2024, the Company entered into a settlement agreement, effective April 2024, (the “Agreement”) with a third-party battery systems supplier (the “Supplier”). Under the Agreement, the Supplier paid to the Company $35.0 million as a recovery of damages, such as significant loss of potential profit due to project delays, as well as additional cost related to locating and purchasing substitute battery solutions from alternative vendors, incurred by the Company (the “Recovery of Damages”) to settle the dispute. On August 16, 2024, the Company received the Recovery of Damages payment contingent upon certain conditions which the Company expects to be met, on a pro-rata basis, during the period until March 31, 2026. The Company accounted for the Recovery of Damages amount under the guidance of ASC 450, Contingencies, and ASC 705, Cost of Sales and Services, and as a result, deemed $25.0 million as a recovery of damages, which will be recognized as income once contingency conditions are met, and $10.0 million as a reduction to the cost of battery systems to be purchased under the Agreement. During the year ended December 31, 2024, the Company recognized income of $9.4 million under “Other operating income” in the consolidated statements of operations and comprehensive income. This amount represents the non-refundable portion of the recovery of damages for which all contingency conditions have been met.

The Company's Heber 1 geothermal power plant located in California experienced an outage following a fire on February 25, 2022 that caused damage primarily to the steam turbine-generator area. In mid-April, 2022 the Company gradually re-started operation of the binary units and in May 2023 the Heber 1 power plant successfully resumed operations. In 2022, the Company recognized $21.8 million of insurance recoveries in respect of the Heber 1 fire event, of which $8.0 million was attributable to property damage and thus recorded against the related receivable and offset the loss from the damaged equipment. The remainder of $13.8 million, was related to business interruption and thus recorded as income under electricity cost of revenues in the consolidated statements of operations and comprehensive income. The Company received all insurance proceeds related to the Heber 1 fire event.

In November 2023, the FASB issued ASU 2023-07 “Segment Reporting–Improvements to Reportable Segments Disclosures (Topic 280)” to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in this ASU (1) require that a public entity disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss; (2) require that a public entity disclose, on an annual and interim basis, an amount for other segment items by reportable segment and a description of its composition; (3) require that a public entity provide all annual disclosures about a reportable segment’s profit or loss and assets currently required by Topic 280 in interim periods; (4) clarify that if the CODM uses more than one measure of a segment’s profit or loss in assessing segment performance and deciding how to allocate resources, a public entity may report one or more of those additional measures; and (5) require that a public entity disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure or measures of segment profit or loss in assessing segment performance and deciding how to allocate resources. The amendments in this ASU are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, and should be

In December 2023, the FASB issued ASU 2023-09 “Income Taxes (Topic 740)–Improvements to Income Tax Disclosures” to enhance the transparency and decision usefulness of income tax disclosures, primarily related to the rate reconciliation and income taxes paid information. The amendments in this ASU require that public entities, on an annual basis, disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. This ASU also requires that all entities disclose, on an annual basis, (1) the amount of income taxes paid disaggregated by federal, state, and foreign taxes, (2) the amount of income taxes paid disaggregated by individual jurisdictions in which income taxes paid is equal to or greater than five percent of total income taxes paid, (3) income or loss from continuing operations before income tax expense or benefit disaggregated between domestic and foreign, and (4) income tax expense or benefit from continuing operations disaggregated by federal, state, and foreign. The amendments in this ASU are effective for annual periods beginning after December 15, 2024, and should be applied on a prospective basis with the option to apply retrospectively. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The Company is still evaluating the impact of this update and plans to implement these amendments in its 2025 consolidated annual financial statements.

In November 2024, the FASB issued ASU 2024-03 “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40)” to improve the disclosure about a public business entity’s expenses and address requests from investors for more detailed information about the types of expenses in commonly presented expense captions. The amendments in this ASU require disclosure of the following items in the notes to the financial statements at each interim and annual reporting date:

1.The amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation, (d) intangible asset amortization, and (e) depreciation, depletion, and amortization recognized as part of oil- and gas-producing activities included in each relevant expense caption. A relevant expense caption is an expense caption presented on the face of the income statement within continuing operations that contain any of the expense categories listed in (a) through (e).

The amendments of this ASU also require that an entity include certain amounts that are already required to be disclosed under current generally accepted accounting principles in the same disclosure as the other disaggregation requirements. The amendments in this ASU are effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, and should be applied either (1) prospectively to financial statements issued for reporting periods after the effective date of the ASU or (2) retrospectively to any or all prior periods presented in the financial statements. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of these amendments on its consolidated financial statements.

In November 2024, the FASB issued ASU 2024-04 “Debt – Debt with Conversion and Other Options (Subtopic 470-20)” to improve the relevance and consistency in application of induced conversion guidance. The amendments in this ASU clarify the assessment of whether a transaction should be accounted for as an induced conversion or extinguishment of convertible debt when changes are made to conversion features as part of an offer to settle the instrument. This ASU is effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. This ASU can be adopted either on a prospective or retrospective basis. Early adoption is permitted. The Company is currently evaluating the potential impact of this guidance on its consolidated financial statements; however, it anticipates that the adoption of ASU 2024-04 will not have a material impact on its consolidated financial statements.
