Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements have been prepared on an accrual basis of accounting in accordance with GAAP and applicable rules and regulations of the SEC regarding financial reporting. Principles of Consolidation These consolidated financial statements include Energy Vault Holdings, Inc., its wholly owned subsidiaries, and a majority owned subsidiary. All intercompany balances and transactions have been eliminated in consolidation. Emerging Growth Company Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or revised, and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s consolidated financial statement with another public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Use of Estimates The preparation of the consolidated financial statements, in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company evaluates its assumptions on an ongoing basis. The Company’s management believes that the estimates, judgment, and assumptions used are reasonable based upon information available at the time they are made. Estimates made by management include, among others, revenue recognition, provision for credit losses, warranty accruals, and stock-based compensation. Due to the inherent uncertainty involved in making assumptions and estimates, changes in circumstances could result in actual results differing from those estimates, and such differences could be material to the Company’s consolidated financial condition and results of operations. Liquidity The accompanying financial statements have been prepared assuming the Company will continue as a going concern, which contemplates continuity of operations, realization of assets, and the satisfaction of liabilities and commitments in the normal course of business. Since our inception in October 2017, we have incurred significant net losses and have used significant cash in our business. As of December 31, 2024 and 2023, we had accumulated deficits of $383.8 million and $248.1 million, respectively, and net losses of $135.8 million and $98.4 million, respectively, for the years ended December 31, 2024 and 2023. We anticipate that we will incur net losses for the foreseeable future and there is no guarantee that we will achieve or maintain profitability. The assessment of liquidity requires management to make estimates of future activity and judgments about whether the Company can meet its obligations and have adequate liquidity to operate. Subsequent to December 31, 2024, the Company took various actions to enhance its liquidity position, which included: •Executing Calistoga Resiliency Center hybrid energy storage system financing arrangements for an aggregate principal amount of $27.8 million. •Executing a Tax Credit Transfer Commitment with a third-party purchaser pursuant to which the Company agreed to sell the ITC generated by the Calistoga Resiliency Center hybrid energy storage system associated with above project financing. The agreement also allows the Company to sell the ITCs for the Cross Trails BESS and Snyder CDU microgrid, pending project financing and completion of the construction capital expenditures. •Executing an Equity Purchase Agreement with an Equity Investor, in which the Company has the right at its sole discretion, but not the obligation, to sell to the Equity Investor, and the Equity Investor is obligated to purchase, up to $25.0 million of newly issued shares of the Company’s common stock. Management believes that its cash, cash equivalents, and restricted cash on hand as of the filing date of this Annual Report, along with the actions taken subsequent to December 31, 2024, will be sufficient to fund our operating activities for at least the next twelve months. Refer to Note 21 - Subsequent Events for further details on the transactions executed subsequent to December 31, 2024. Segment Reporting The Company reports its operating results and financial information in one operating and reportable segment. Our chief operating decision maker (“CODM”), which is our chief executive officer, reviews our operating results on a consolidated basis and uses that consolidated financial information to make operating decisions, assess financial performance, and allocate resources. Concentration of Credit and Other Risks Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, accounts receivable, and customer financings receivable. Risks associated with cash and cash equivalents and restricted cash are mitigated by banking with creditworthy institutions. Such balances with any one institution may, at times, be in excess of federally insured amounts. As of December 31, 2024, one customer accounted for 100% of accounts receivable. As of December 31, 2023, one customer accounted for 92% of accounts receivable. As of December 31, 2024 and 2023, one customer accounted for 100% of the customer financing receivable. Revenue from two customers accounted for 75% and 19% of total revenue, respectively, for the year ended December 31, 2024 and revenue from three customers accounted for 64%, 22%, and 13% of total revenue, respectively, for the year ended December 31, 2023. Foreign Currency Assets and liabilities denominated in a foreign currency are translated into U.S dollars using the exchange rates in effect at the balance sheet date. Revenue and expense accounts are translated at the average exchange rates during the periods. The impact of exchange rate fluctuations from translation of assets and liabilities is included in accumulated other comprehensive loss, a component of stockholders’ equity. As of December 31, 2024, accumulated other comprehensive loss included a $0.1 million loss related to currency translation adjustments. As of December 31, 2023, accumulated other comprehensive loss included a $0.3 million loss related to currency translation adjustments. Gains and losses resulting from foreign currency transactions are included in other income (expense), net in the accompanying consolidated statements of operations and comprehensive loss. Fair Value Measurements ASC 820, Fair Value Measurement (“ASC 820”), establishes a fair value hierarchy for instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value as follows: Level I — Inputs which include quoted prices in active markets for identical assets and liabilities. Level II — Inputs other than Level I that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level III — Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. Revenue Recognition The Company recognizes revenue from contracts with customers in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”). Under ASC 606, revenue is recognized when, or as, control of promised goods and services is transferred to customers, and the amount of revenue recognized reflects the consideration to which the Company expects to be entitled in exchange for the goods and services transferred. The Company determines revenue recognition through the following steps: (1)Identification of the contract, or contracts, with a customer. (2)Identification of the performance obligations in the contract. (3)Determination of the transaction price. (4)Allocation of the transaction price to the performance obligations in the contract. (5)Recognition of revenue when, or as, a performance obligation is satisfied. Once a contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations. Arrangements that include rights to additional goods or services that are exercisable at a customer’s discretion are generally considered options. The Company assesses if these options provide a material right to the customer and if so, they are considered performance obligations. The identification of material rights requires judgments related to the determination of the value of the underlying good or service relative to the option exercise price. The Company assesses whether each promised good or service is distinct for the purposes of identifying performance obligations in the contract. This assessment involves subjective determination and requires management to make judgments about the individual promised goods or services and whether such are separable from the other aspects of the contractual relationship. Promised goods and services are considered to be distinct provided that: (i) the customer can benefit from the good or service either on its own or together with the other resources that are readily available to the customer (that is, the good or service is capable of being distinct) and (ii) the entity’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract (that is, the promise to transfer the good or service is distinct within the context of the contract). The Company also considers the intended benefit of the contract in assessing whether a promised good or service is separately identifiable from other promises in the contract. If a promised good or service is not distinct, an entity is required to combine that good or service with other promised goods or services until it identifies a bundle of goods or services that is distinct. The transaction price is determined and allocated to the identified performance obligations in proportion to their stand-alone selling prices (“SSP”) on a relative SSP basis. SSP is determined at contract inception and is not updated to reflect changes between contract inception and when the performance obligations are satisfied. Determining the SSP for performance obligations requires significant judgment. In developing the SSP for a performance obligation, the Company considers applicable market conditions and relevant entity-specific factors, including factors that were contemplated in negotiating the agreement with the customer and estimated costs. In determining the transaction price, the Company adjusts consideration for the effects of the time value of money if the timing of payments provides the Company with a significant benefit of financing. When a contract provides the customer with a significant benefit of financing, the Company recognizes a customer financing receivable and recognizes interest income separate from the revenue recognized on the contracts with customers. The Company does not assess whether a contract has a significant financing component if the expectation at contract inception is such that the period between payment and the transfer of the promised goods or services will be one year or less. The Company recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) each performance obligation is satisfied, either at a point in time or over time. Over time revenue recognition is based on the use of an output or input method. Sale of Energy Storage Products: The Company sells its energy storage products to utility companies and independent power producers. The Company enters into (i) engineering, procurement, and construction (“EPC”) contracts to design, construct, install, and transfer fully operational energy storage systems and (ii) engineered equipment (“EEQ”) contracts to design and deliver energy storage equipment. Each storage project is customized depending on the customer’s energy storage needs. Customer payments are due upon meeting certain milestones that are consistent with contract-specific phases of a project. The Company determines the transaction price based on the consideration expected to be received, which includes estimates of liquidated damages or other variable consideration. Generally, each EPC contract contains one performance obligation to design, construct, install, and deliver a fully operational energy storage system. Generally each EEQ contract contains multiple performance obligations, including separate performance obligations (i) to supply equipment and (ii) to provide specialized technical services. Multiple contracts entered into with the same customer and near the same time are combined in accordance with ASC 606. In these situations, the contract prices are aggregated and then allocated to each performance obligation based upon their relative stand-alone selling price. For EPC contracts, the Company recognizes revenue over time as a result of the continuous transfer of control of its products to the customer. The continuous transfer of control to the customer is supported by clauses in the contracts that provide enforceable rights to payment of the transaction price associated with work performed to date for products that do not have an alternative use to the Company and/or the project is built on the customer’s land that is under the customer’s control. For equipment sales in EEQ contracts, the Company recognizes revenue at a point in time, which corresponds to delivery of the equipment to the customer. For technical services provided in EEQ contracts, the Company recognizes revenue over time as the Company performs the required services. Revenue for performance obligations satisfied over time is recognized using the percentage of completion method based on cost incurred as a percentage of total estimated contract costs. Contract costs include all direct materials and labor costs related to contract performance. Pre-contract costs with no future benefit are expensed in the period in which they are incurred. Since the revenue recognition of these contracts depends on estimates, which are assessed continually during the term of the contract, recognized revenues and profit are subject to revisions as the contract progresses to completion. The cumulative effects of revisions of estimated total contract costs and revenues, together with any contract reserves which may be deemed appropriate, are recorded in the period in which the facts and changes in circumstances become known. Due to uncertainties inherent in the estimation process, it is reasonably possible that these estimates will be revised in a different period. When a loss is forecasted for a contract, the full amount of the anticipated loss is recognized in the period in which it is determined that a loss will incur. The Company’s contracts generally provide customers the right to liquidated damages (“LDs”) against Energy Vault in the event specified milestones are not met on time, or certain performance metrics are not met upon or after the substantial completion date. LDs are accounted for as variable consideration, and the contract price is reduced by the expected penalty or LD amount when recognizing revenue. Variable consideration is included in the transaction price only to the extent that it is improbable that a significant reversal in the amount of cumulative revenue recognized will occur when the uncertainty is resolved. Estimating variable consideration requires certain estimates and assumptions, including whether and by how much a project will be delayed. The existence and measurement of liquidated damages may also be impacted by the Company’s judgment about the probability of favorable outcomes of customer disputes involving whether certain events qualify as force majeure or the reason for the events that caused project delays. Variable consideration for LDs is estimated using the expected value of the consideration to be received. If Energy Vault has a claim against the customer for an amount not specified in the contract, such claim is recognized as an increase to the contract price when it is legally enforceable, which is usually upon signing a respective change order or equivalent document confirming the claim acceptance by the customer. The Company offers limited warranties on its energy storage products which provide the customer assurance that the products will function as the parties intended because it complies with agreed-upon specifications and are free from defects. These assurance-type warranties are not treated as a separate revenue performance obligation and are accounted for as guarantees under GAAP. Own and Operate Energy Storage Projects: To date, the Company has not recognized any revenue from its owned energy storage systems. The Company has entered into tolling agreements in which the Company will sell the energy produced by its energy storage systems. These arrangements are expected to be accounted for under ASC 842, Leases, and accounting recognition does not begin until an energy storage system is made available to a customer. This method of revenue recognition will be finalized upon the commencement of one of the Company’s owned energy storage projects. Software Licensing: The Company licenses its energy management software solutions to customers. Software licensing customers do not receive legal title or ownership of the software. Customers receive access to the software platform and related support services as part of a software licensing contract. We consider these obligations to be a series of distinct services that comprise a single performance obligation because they are substantially the same and have the same pattern of transfer. Revenue is recognized over time on a straight-line basis over the term of the contract. Long-Term Service Arrangements: The Company enters into long-term service arrangements to provide operation and maintenance services to customer-owned energy storage systems. The Company accounts for this service as a separate performance obligation from the sale of energy storage products. Revenue is recognized over time on a straight-line basis over the term of the contract. The Company believes using a time-based method to measure progress is appropriate as the performance obligation is satisfied evenly over the term of the services. Licensing of IP: The Company enters into licensing agreements of its IP that are within the scope of ASC 606. The terms of such licensing agreements include the license of functional IP, given the functionality of the IP is not expected to change substantially as a result of the licensor’s ongoing activities. The transaction price allocated to the licensing of IP is recognized as revenue at a point in time when the licensed IP is made available for the customer’s use and benefit. Certain licensing agreements contain a significant financing component due to the customer having extended payment terms. The amounts due from customers under extended payment terms are included in the line item, customer financing receivable, on the consolidated balance sheets. Royalty Revenue: In connection with entering into IP licensing agreements, the Company also enters into royalty agreements whereby the customer agrees to pay the Company a percentage of the customer’s future sales revenue that is generated by using the Company’s IP. The Company has not recognized any royalty revenue to date, but will recognize royalty revenue at the point in time when the customer’s sales occur. Cash, Cash Equivalents, and Restricted Cash The Company considers all highly liquid investments purchased with an original or remaining maturity of three months or less to be cash equivalents. At December 31, 2024, the Company maintained investments in money market accounts totaling $9.9 million, including $9.5 million in U.S. government money market funds. At December 31, 2023, the Company maintained money market funds totaling $98.4 million, including $98.0 million in U.S. government money market funds. Restricted cash as of December 31, 2024 and 2023 primarily consisted of cash held by banks as collateral for the Company’s letters of credit. Accounts Receivable Accounts receivable represents amounts that have an unconditional right to consideration, have been billed to customers, and do not bear interest. Receivables are carried at the original invoiced amount, less an allowance for any potential uncollectible amounts. Customer Financing Receivable Customer financing receivable includes amounts due from a customer related to a licensing agreement under extended payment terms which contains a significant financing component. An interest rate is not stated in this agreement and is imputed using the effective interest method when recognizing interest income. The imputed interest rate on the note is 8.5%. Interest income on the customer financing receivable was $0.8 million and $0.9 million for the years ended December 31, 2024 and 2023, respectively. Effective December 31, 2024, the Company placed the customer financing receivable on non-accrual status and has discontinued the accrual of future interest income. The Company placed the customer financing receivable in non-accrual status because the customer did not make its first two installment payments in 2024, and both installments are more than 90 days past due as of December 31, 2024. The amortized cost basis for the Company’s customer financing receivable was $11.5 million and $10.7 million as of December 31, 2024 and 2023, respectively. Allowance for Credit Losses The Company estimates expected uncollectible amounts related to its accounts receivable, customer financing receivable, and contract asset balances as of the end of each reporting period, and presents those financial asset balances net of an allowance for expected credit losses in the consolidated balance sheets. Due to the Company’s limited operating history, the Company generally utilizes a probability-of-default (“PD”) and loss-given-default (“LGD”) methodology to calculate the allowance for credit losses for each customer by type of financial asset. The Company derives its PD and LGD rates using historical rates for corporate bonds as published by Moody’s. The Company uses PD and LGD rates that correspond to the customer’s credit rating and period of time in which the financial asset is expected to remain outstanding. For significantly past due receivables, such as the customer financing receivable and refundable contribution (defined in Note 3), the Company determines specific allowances for each receivable. Inventory Inventory consists of equipment and spare parts, which are used in ongoing battery storage projects for sale. Inventory is stated at the lower of cost or net realizable value with cost being determined by the specific identification method. Costs include the cost of purchase and other costs incurred in bringing the inventories to their present location and condition. The Company periodically reviews its inventory for potential obsolescence and write down of its inventory, as appropriate, to net realizable value based on its assessment of market conditions. Assets held for sale The Company classifies assets to be disposed of as held for sale in the period in which they are available for sale in their present condition and when the sale is probable and expected to be completed within one year. Assets classified as held for sale are measured at the lower of their carrying amount or fair value less costs to sell. Further, the Company does not record depreciation and amortization expense on assets that are classified as held for sale. Property and Equipment, Net Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. Maintenance and repairs are charged to expense as incurred. When assets are retired or sold, the cost and related accumulated depreciation are removed from the consolidated balance sheet and any resulting gain or loss is reflected in operating expenses in the period realized. Impairment of Long-Lived Assets The Company reviews long-lived assets, primarily comprised of property and equipment, intangible assets, and operating right-of-use assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by comparison of the carrying amount to the future undiscounted net cash flows which the assets are expected to generate. If the carrying value of the assets exceeds the sum of the estimated future cash flows, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceed their fair value. Intangible Assets The Company’s intangible assets consist of software development costs related to software to be sold or leased externally. These development costs are capitalized upon the establishment of technological feasibility for a product in accordance with ASC 985-20, Software - Costs of Software to be Sold, Leased, or Marketed. Amortization of capitalized software costs begins at the time that each software product becomes available for general release to customers. Once a software application is available for general release and is placed in service, the Company amortizes the capitalized costs on a product basis by the greater of the straight-line method over the estimated economic life of the product, or the ratio that current gross revenues for a product bear to the total current and anticipated future gross revenues for that product. The useful life of our external-use software development costs is generally expected to be 5 years. Investment in Equity Securities During 2022 and 2023, the Company made a strategic investment and purchased equity securities in KORE, a U.S. manufacturer of battery cells and modules. The Company’s ownership in KORE does not provide the Company with the ability to exercise significant influence. These equity securities do not have a readily determinable fair value and are recorded at cost, less any impairment, plus or minus adjustments related to observable transactions for the same or similar securities, with unrealized gains and losses included in earnings. The carrying value of the Company’s investment in equity securities is included in the line item, investments, long term portion, in the consolidated balance sheets. Leases The Company determines if a contract contains a lease at its inception based on whether or not the Company has the right to control the asset during the contract period and other facts and circumstances. Right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets are classified as either operating or finance leases. Upon commencement of the lease, a ROU asset and corresponding lease liability are recognized for all operating and finance leases. The Company has elected the short-term lease exemption, which does not require a ROU asset or lease liability to be recognized when the lease term is 12 months or less and does not include an option to purchase the underlying asset that the lessee is reasonably certain to exercise. Upon commencement of the lease, ROU assets are recognized based on the initial measurement of the lease liability and adjusted for any lease payments made before commencement date of the lease, less any lease incentives and including any initial direct costs incurred. Lease liabilities are initially measured at the present value of future minimum lease payments over the lease term. The discount rate used to determine the present value is the rate implicit in the lease unless that rate cannot be determined, in which case Company’s incremental borrowing rate is used, which is based on the estimated interest rate for collateralized borrowing over a similar term of the lease at commencement date. Rights to extend or terminate a lease are included in the lease term when there is reasonable certainty the right will be exercised. Factors used to assess reasonable certainty of rights to extend or terminate a lease include current and forecasted lease improvement plans, anticipated changes in development strategies, historical practice in extending similar contracts and current market conditions. Operating lease expense is recognized on a straight-line basis over the lease term. Finance lease ROU assets are amortized on a straight-line basis over the lesser of the lease term or the estimated useful life of the leased asset. Amortization of finance lease ROU assets is included in depreciation and amortization. Operating lease ROU assets are recognized on the consolidated balance sheets in the line item, operating lease right-of-use assets, and finance lease ROU assets are recognized on the consolidated balance sheets within the line item, property and equipment, net. Defined Benefit Pension Obligation The Company’s wholly owned subsidiary in Switzerland has a defined benefit pension obligation covering retirement and other long-term benefits of the local employees. Accrued pension costs are developed using actuarial principles and assumptions which consider a number of factors, including estimates for the discount rate, expected long-term rate of return on assets and mortality. Changes in these estimates would impact the amounts that the Company records in the consolidated financial statements. Warrants The Company accounts for warrants for shares of the Company’s common stock that are not indexed to its own stock as liabilities at fair value on the consolidated balance sheets. The warrants are subject to remeasurement at each balance sheet date and any change in fair value is recognized in the Company’s consolidated statements of operations and comprehensive loss. For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in-capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded as a liability at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss in the consolidated statements of operations and comprehensive loss. Earn-Out Shares In connection with the Merger, eligible Legacy Energy Vault stockholders immediately prior to the Closing, have the contingent right to receive an aggregate of 9.0 million shares of the Company’s common stock (“Earn-Out Shares”) upon the Company achieving each Earn-Out Triggering Event (defined below) during the period beginning on the 90th day following the closing of the Merger and ending on the third anniversary of such date. An “Earn-Out Triggering Event” means the date on which the closing price of the Company’s common stock quoted on the NYSE is greater than or equal to certain specified prices for any 20 trading days within a 30 consecutive day trading period. The Earn-Out Shares were recognized at fair value upon the closing of the Merger and classified in stockholders’ equity. Because the Merger was accounted for as a reverse recapitalization, the issuance of the Earn-Out Shares was treated as a deemed dividend and since the Company does not have retained earnings, the issuance was recorded within additional-paid-in capital (“APIC”) and had a net nil impact on APIC. Research and Development Expenses Research and development costs are expensed as incurred. Research and development costs consist of salaries and other personnel related expenses, engineering expenses, product development costs and facility costs. Advertising Costs Advertising costs are expensed as incurred and are reflected in the line item, sales and marketing, in the consolidated statements of operations and comprehensive loss. Advertising expenses were $0.2 million and $0.5 million for the years ended December 31, 2024 and 2023, respectively. Stock-Based Compensation The Company issues stock-based compensation awards to employees, directors, and non-employees in the form of stock options and restricted stock units (“RSUs”). The Company measures and recognizes compensation expense for stock-based awards based on the award’s fair value on the date of the grant. The Company accounts for forfeitures of stock-based awards when they occur. The fair value of RSUs that vest based on service conditions is measured using the fair value of the Company’s common stock on the date of the grant. The fair value of RSUs that vest based on market conditions is measured using a Monte Carlo simulation model on the date of the grant. The fair value of stock options that vest based on service conditions is measured using the Black-Scholes option pricing model on the date of the grant. The Monte Carlo simulation model and the Black-Scholes option pricing model require the input of highly subjective assumptions, including the fair value of the Company’s common stock, the expected term of the award, the expected volatility of the Company’s common stock, risk-free interest rates, and the expected dividend yield of the Company’s common stock. This assumption used to determine the fair value of the awards represent management’s best estimates. These estimates involve inherit uncertainties and the application of management’s judgment. The fair value of awards is recognized on a straight-line basis over the requisite service period. The fair value of the market-based RSUs is recognized over the requisite service period regardless of whether or not the RSUs ultimately vest and convert to common stock. Income Taxes The Company accounts for income taxes in accordance with ASC 740, Income Taxes (“ASC 740”). ASC 740 prescribes the use of the liability method, whereby deferred tax asset and liability account balances are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates that will be in effect when the differences are expected to reverse. Deferred income tax balances reflect the effects of temporary differences between the carrying amounts of assets and liabilities and their tax bases and are stated at enacted tax rates expected to be in effect when taxes are actually paid or recovered. Deferred tax assets are evaluated for future realization and reduced by a valuation allowance to the extent the Company believes they will not be realized. The Company’s policy is to recognize interest and penalties related to uncertain tax positions, if any, in the income tax provision. Net Loss Per Share Basic net loss per share of common stock is calculated by dividing net loss by the weighted average number of common shares outstanding for the applicable period. Diluted net loss is computed based on the weighted average number of common shares outstanding increased by the number of additional shares that would have been outstanding had the potentially dilutive common shares been issued, including any dilutive effect from outstanding warrants, outstanding stock options, or unvested RSUs, and reduced by the number of shares the Company could have repurchased with the proceeds from the issuance of the potentially dilutive shares. Potentially dilutive instruments are excluded from the per share calculation because the Company is in a net loss position and they would therefore be anti-dilutive. Non-controlling interest In May 2024, the Company’s consolidated subsidiary, Cetus Energy, Inc. (“Cetus”), issued a share-based payment award to an employee of Cetus, representing a non-controlling interest. A non-controlling interest in a subsidiary is considered an ownership interest in a majority-owned subsidiary that is not attributable to the parent. The Company includes non-controlling interest as a component of stockholders’ equity on the Company’s consolidated balance sheets. The Company owns 85% of Cetus. Recently Adopted Accounting Standards In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2023-07, Segment Reporting (Topic 280) — Improvements to Reportable Segment Disclosures. The ASU improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. We adopted this standard effective for the reporting periods noted above, with retrospective application to all prior periods presented in the financial statements. The adoption of this standard did not have any impact on the Company’s financial condition, results of operations and comprehensive loss, or cash flows, but resulted in enhancements to our segment disclosures, primarily related to our significant segment expenses. See Note 17, Segment Reporting, for further information. Recent Accounting Standards Issued, But Not Yet Adopted In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topics 740): Improvements to Income Tax Disclosures to expand the disclosure requirements for income taxes. Upon adoption we will be required to disclose additional specified categories in the rate reconciliation in both percentage and dollar amounts. We will also be required to disclose the amount of income taxes paid disaggregated by jurisdiction, among other disclosure requirements. The standard can be applied either prospectively or retrospectively. We will adopt the standard in our 2025 annual period and are currently assessing the effect that the updated standard will have on our financial statement disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (Subtopic 220-40) — Disaggregation of Income Statement Expenses. The ASU requires the disclosure of additional information about specific costs and expense categories in the notes to the consolidated financial statements. The standard is effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted. The standard should be applied on a prospective basis with the option to apply the standard retrospectively. We are currently evaluating the impact of this standard on our disclosures.

Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or

This may make comparison of the Company’s consolidated financial statement with another public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

The preparation of the consolidated financial statements, in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company evaluates its assumptions on an ongoing basis. The Company’s management believes that the estimates, judgment, and assumptions used are reasonable based upon information available at the time they are made. Estimates made by management include, among others, revenue recognition, provision for credit losses, warranty accruals, and stock-based compensation. Due to the inherent uncertainty involved in making assumptions and estimates, changes in circumstances could result in actual results differing from those estimates, and such differences could be material to the Company’s consolidated financial condition and results of operations.

Since our inception in October 2017, we have incurred significant net losses and have used significant cash in our business. As of December 31, 2024 and 2023, we had accumulated deficits of $383.8 million and $248.1 million, respectively, and net losses of $135.8 million and $98.4 million, respectively, for the years ended December 31, 2024 and 2023. We anticipate that we will incur net losses for the foreseeable future and there is no guarantee that we will achieve or maintain profitability.

The assessment of liquidity requires management to make estimates of future activity and judgments about whether the Company can meet its obligations and have adequate liquidity to operate. Subsequent to December 31, 2024, the Company took various actions to enhance its liquidity position, which included:

•Executing a Tax Credit Transfer Commitment with a third-party purchaser pursuant to which the Company agreed to sell the ITC generated by the Calistoga Resiliency Center hybrid energy storage system associated with above project financing. The agreement also allows the Company to sell the ITCs for the Cross Trails BESS and Snyder CDU microgrid, pending project financing and completion of the construction capital expenditures.

•Executing an Equity Purchase Agreement with an Equity Investor, in which the Company has the right at its sole discretion, but not the obligation, to sell to the Equity Investor, and the Equity Investor is obligated to purchase, up to $25.0 million of newly issued shares of the Company’s common stock.

Management believes that its cash, cash equivalents, and restricted cash on hand as of the filing date of this Annual Report, along with the actions taken subsequent to December 31, 2024, will be sufficient to fund our operating activities for at least the next twelve months. Refer to Note 21 - Subsequent Events for further details on the transactions executed subsequent to December 31, 2024.

The Company reports its operating results and financial information in one operating and reportable segment. Our chief operating decision maker (“CODM”), which is our chief executive officer, reviews our operating results on a consolidated basis and uses that consolidated financial information to make operating decisions, assess financial performance, and allocate resources.

Assets and liabilities denominated in a foreign currency are translated into U.S dollars using the exchange rates in effect at the balance sheet date. Revenue and expense accounts are translated at the average exchange rates during the periods. The impact of exchange rate fluctuations from translation of assets and liabilities is included in accumulated other comprehensive loss, a component of stockholders’ equity. As of December 31, 2024, accumulated other comprehensive loss included a $0.1 million loss related to currency translation adjustments. As of December 31, 2023, accumulated other comprehensive loss included a $0.3 million loss related to currency translation adjustments.

ASC 820, Fair Value Measurement (“ASC 820”), establishes a fair value hierarchy for instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value as follows:

Level II — Inputs other than Level I that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

The Company recognizes revenue from contracts with customers in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”). Under ASC 606, revenue is recognized when, or as, control of promised goods and services is transferred to customers, and the amount of revenue recognized reflects the consideration to which the Company expects to be entitled in exchange for the goods and services transferred. The Company determines revenue recognition through the following steps:

Once a contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations. Arrangements that include rights to additional goods or services that are exercisable at a customer’s discretion are generally considered options. The Company assesses if these options provide a material right to the customer and if so, they are considered performance obligations. The identification of material rights requires judgments related to the determination of the value of the underlying good or service relative to the option exercise price.

The Company assesses whether each promised good or service is distinct for the purposes of identifying performance obligations in the contract. This assessment involves subjective determination and requires management to make judgments about the individual promised goods or services and whether such are separable from the other aspects of the contractual relationship. Promised goods and services are considered to be distinct provided that: (i) the customer can benefit from the good or service either on its own or together with the other resources that are readily available to the customer (that is, the good or service is capable of being distinct) and (ii) the entity’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract (that is, the promise to transfer the good or service is distinct within the context of the contract). The Company also considers the intended benefit of the contract in assessing whether a promised good or service is separately identifiable from other promises in the contract. If a promised good or service is not distinct, an entity is required to combine that good or service with other promised goods or services until it identifies a bundle of goods or services that is distinct.

The transaction price is determined and allocated to the identified performance obligations in proportion to their stand-alone selling prices (“SSP”) on a relative SSP basis. SSP is determined at contract inception and is not updated to reflect changes between contract inception and when the performance obligations are satisfied. Determining the SSP for performance obligations requires significant judgment. In developing the SSP for a performance obligation, the Company considers applicable market conditions and relevant entity-specific factors, including factors that were contemplated in negotiating the agreement with the customer and estimated costs.

In determining the transaction price, the Company adjusts consideration for the effects of the time value of money if the timing of payments provides the Company with a significant benefit of financing. When a contract provides the customer with a significant benefit of financing, the Company recognizes a customer financing receivable and recognizes interest income separate from the revenue recognized on the contracts with customers. The Company does not assess whether a contract has a significant financing component if the expectation at contract inception is such that the period between payment and the transfer of the promised goods or services will be one year or less.

The Company recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) each performance obligation is satisfied, either at a point in time or over time. Over time revenue recognition is based on the use of an output or input method.

Sale of Energy Storage Products: The Company sells its energy storage products to utility companies and independent power producers. The Company enters into (i) engineering, procurement, and construction (“EPC”) contracts to design, construct, install, and transfer fully operational energy storage systems and (ii) engineered equipment (“EEQ”) contracts to design and deliver energy storage equipment. Each storage project is customized depending on the customer’s energy storage needs.

Customer payments are due upon meeting certain milestones that are consistent with contract-specific phases of a project. The Company determines the transaction price based on the consideration expected to be received, which includes estimates of liquidated damages or other variable consideration. Generally, each EPC contract contains one performance obligation to design, construct, install, and deliver a fully operational energy storage system. Generally each EEQ contract contains multiple performance obligations, including separate performance obligations (i) to supply equipment and (ii) to provide specialized technical services. Multiple contracts entered into with the same customer and near the same time are combined in accordance with ASC 606. In these situations, the contract prices are aggregated and then allocated to each performance obligation based upon their relative stand-alone selling price.

For EPC contracts, the Company recognizes revenue over time as a result of the continuous transfer of control of its products to the customer. The continuous transfer of control to the customer is supported by clauses in the contracts that provide enforceable rights to payment of the transaction price associated with work performed to date for products that do not have an alternative use to the Company and/or the project is built on the customer’s land that is under the customer’s control. For equipment sales in EEQ contracts, the Company recognizes revenue at a point in time, which corresponds to delivery of the equipment to the customer. For technical services provided in EEQ contracts, the Company recognizes revenue over time as the Company performs the required services.

Revenue for performance obligations satisfied over time is recognized using the percentage of completion method based on cost incurred as a percentage of total estimated contract costs. Contract costs include all direct materials and labor costs related to contract performance. Pre-contract costs with no future benefit are expensed in the period in which they are incurred. Since the revenue recognition of these contracts depends on estimates, which are assessed continually during the term of the contract, recognized revenues and profit are subject to revisions as the contract progresses to completion. The cumulative effects of revisions of estimated total contract costs and revenues, together with any contract reserves which may be deemed appropriate, are recorded in the period in which the facts and changes in circumstances become known. Due to uncertainties inherent in the estimation process, it is reasonably possible that these estimates will be revised in a different period. When a loss is forecasted for a contract, the full amount of the anticipated loss is recognized in the period in which it is determined that a loss will incur.

The Company’s contracts generally provide customers the right to liquidated damages (“LDs”) against Energy Vault in the event specified milestones are not met on time, or certain performance metrics are not met upon or after the substantial completion date. LDs are accounted for as variable consideration, and the contract price is reduced by the expected penalty or LD amount when recognizing revenue. Variable consideration is included in the transaction price only to the extent that it is improbable that a significant reversal in the amount of cumulative revenue recognized will occur when the uncertainty is resolved. Estimating variable consideration requires certain estimates and assumptions, including whether and by how much a project will be delayed. The existence and measurement of liquidated damages may also be impacted by the Company’s judgment about the probability of favorable outcomes of customer disputes involving whether certain events qualify as force majeure or the reason for the events that caused project delays. Variable consideration for LDs is estimated using the expected value of the consideration to be received. If Energy Vault has a claim against the customer for an amount not specified in the contract, such claim is recognized as an increase to the contract price when it is legally enforceable, which is usually upon signing a respective change order or equivalent document confirming the claim acceptance by the customer.

The Company offers limited warranties on its energy storage products which provide the customer assurance that the products will function as the parties intended because it complies with agreed-upon specifications and are free from defects. These assurance-type warranties are not treated as a separate revenue performance obligation and are accounted for as guarantees under GAAP.

Own and Operate Energy Storage Projects: To date, the Company has not recognized any revenue from its owned energy storage systems. The Company has entered into tolling agreements in which the Company will sell the energy produced by its energy storage systems. These arrangements are expected to be accounted for under ASC 842, Leases, and accounting recognition does not begin until an energy storage system is made available to a customer. This method of revenue recognition will be finalized upon the commencement of one of the Company’s owned energy storage projects.

Software Licensing: The Company licenses its energy management software solutions to customers. Software licensing customers do not receive legal title or ownership of the software. Customers receive access to the software platform and related support services as part of a software licensing contract. We consider these obligations to be a series of distinct services that comprise a single performance obligation because they are substantially the same and have the same pattern of transfer. Revenue is recognized over time on a straight-line basis over the term of the contract.

Long-Term Service Arrangements: The Company enters into long-term service arrangements to provide operation and maintenance services to customer-owned energy storage systems. The Company accounts for this service as a separate performance obligation from the sale of energy storage products. Revenue is recognized over time on a straight-line basis over the term of the contract. The Company believes using a time-based method to measure progress is appropriate as the performance obligation is satisfied evenly over the term of the services.

Licensing of IP: The Company enters into licensing agreements of its IP that are within the scope of ASC 606. The terms of such licensing agreements include the license of functional IP, given the functionality of the IP is not expected to change substantially as a result of the licensor’s ongoing activities. The transaction price allocated to the licensing of IP is recognized as revenue at a point in time when the licensed IP is made available for the customer’s use and benefit. Certain licensing agreements contain a significant financing component due to the customer having extended payment terms. The amounts due from customers under extended payment terms are included in the line item, customer financing receivable, on the consolidated balance sheets.

Royalty Revenue: In connection with entering into IP licensing agreements, the Company also enters into royalty agreements whereby the customer agrees to pay the Company a percentage of the customer’s future sales revenue that is generated by using the Company’s IP. The Company has not recognized any royalty revenue to date, but will recognize royalty revenue at the point in time when the customer’s sales occur.

The Company considers all highly liquid investments purchased with an original or remaining maturity of three months or less to be cash equivalents. At December 31, 2024, the Company maintained investments in money market accounts totaling $9.9 million, including $9.5 million in U.S. government money market funds. At December 31, 2023, the Company maintained money market funds totaling $98.4 million, including $98.0 million in U.S. government money market funds.

Customer financing receivable includes amounts due from a customer related to a licensing agreement under extended payment terms which contains a significant financing component. An interest rate is not stated in this agreement and is imputed using the effective interest method when recognizing interest income. The imputed interest rate on the note is 8.5%. Interest income on the customer financing receivable was $0.8 million and $0.9 million for the years ended December 31, 2024 and 2023, respectively.

Effective December 31, 2024, the Company placed the customer financing receivable on non-accrual status and has discontinued the accrual of future interest income. The Company placed the customer financing receivable in non-accrual status because the customer did not make its first two installment payments in 2024, and both installments are more than 90 days past due as of December 31, 2024.

The Company estimates expected uncollectible amounts related to its accounts receivable, customer financing receivable, and contract asset balances as of the end of each reporting period, and presents those financial asset balances net of an allowance for expected credit losses in the consolidated balance sheets. Due to the Company’s limited operating history, the Company generally utilizes a probability-of-default (“PD”) and loss-given-default (“LGD”) methodology to calculate the allowance for credit losses for each customer by type of financial asset. The Company derives its PD and LGD rates using historical rates for corporate bonds as published by Moody’s. The Company uses PD and LGD rates that correspond to the customer’s credit rating and period of time in which the financial asset is expected to remain outstanding.

Inventory consists of equipment and spare parts, which are used in ongoing battery storage projects for sale. Inventory is stated at the lower of cost or net realizable value with cost being determined by the specific identification method. Costs include the cost of purchase and other costs incurred in bringing the inventories to their present location and condition. The Company periodically reviews its inventory for potential obsolescence and write down of its inventory, as appropriate, to net realizable value based on its assessment of market conditions.

The Company classifies assets to be disposed of as held for sale in the period in which they are available for sale in their present condition and when the sale is probable and expected to be completed within one year. Assets classified as held for sale are measured at the lower of their carrying amount or fair value less costs to sell. Further, the Company does not record depreciation and amortization expense on assets that are classified as held for sale.

Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. Maintenance and repairs are charged to expense as incurred. When assets are retired or sold, the cost and related accumulated depreciation are removed from the consolidated balance sheet and any resulting gain or loss is reflected in operating expenses in the period realized.

The Company reviews long-lived assets, primarily comprised of property and equipment, intangible assets, and operating right-of-use assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by comparison of the carrying amount to the future undiscounted net cash flows which the assets are expected to generate. If the carrying value of the assets exceeds the sum of the estimated future cash flows, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceed their fair value.

The Company’s intangible assets consist of software development costs related to software to be sold or leased externally. These development costs are capitalized upon the establishment of technological feasibility for a product in accordance with ASC 985-20, Software - Costs of Software to be Sold, Leased, or Marketed. Amortization of capitalized software costs begins at the time that each software product becomes available for general release to customers. Once a software application is available for general release and is placed in service, the Company amortizes the capitalized costs on a product basis by the greater of the straight-line method over the estimated economic life of the product, or the ratio that current gross revenues for a product bear to the total current and anticipated future gross revenues for that product. The useful life of our external-use software development costs is generally expected to be 5 years.

During 2022 and 2023, the Company made a strategic investment and purchased equity securities in KORE, a U.S. manufacturer of battery cells and modules. The Company’s ownership in KORE does not provide the Company with the ability to exercise significant influence. These equity securities do not have a readily determinable fair value and are recorded at cost, less any impairment, plus or minus adjustments related to observable transactions for the same or similar securities, with unrealized gains and losses included in earnings. The carrying value of the Company’s investment in equity securities is included in the line item, investments, long term portion, in the consolidated balance sheets.

The Company determines if a contract contains a lease at its inception based on whether or not the Company has the right to control the asset during the contract period and other facts and circumstances. Right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease.

Upon commencement of the lease, ROU assets are recognized based on the initial measurement of the lease liability and adjusted for any lease payments made before commencement date of the lease, less any lease incentives and including any initial direct costs incurred. Lease liabilities are initially measured at the present value of future minimum lease payments over the lease term.

The discount rate used to determine the present value is the rate implicit in the lease unless that rate cannot be determined, in which case Company’s incremental borrowing rate is used, which is based on the estimated interest rate for collateralized borrowing over a similar term of the lease at commencement date.

Rights to extend or terminate a lease are included in the lease term when there is reasonable certainty the right will be exercised. Factors used to assess reasonable certainty of rights to extend or terminate a lease include current and forecasted lease improvement plans, anticipated changes in development strategies, historical practice in extending similar contracts and current market conditions.

Operating lease expense is recognized on a straight-line basis over the lease term. Finance lease ROU assets are amortized on a straight-line basis over the lesser of the lease term or the estimated useful life of the leased asset. Amortization of finance lease ROU assets is included in depreciation and amortization.

The Company’s wholly owned subsidiary in Switzerland has a defined benefit pension obligation covering retirement and other long-term benefits of the local employees. Accrued pension costs are developed using actuarial principles and assumptions which consider a number of factors, including estimates for the discount rate, expected long-term rate of return on assets and mortality. Changes in these estimates would impact the amounts that the Company records in the consolidated financial statements.

The Company accounts for warrants for shares of the Company’s common stock that are not indexed to its own stock as liabilities at fair value on the consolidated balance sheets. The warrants are subject to remeasurement at each balance sheet date and any change in fair value is recognized in the Company’s consolidated statements of operations and comprehensive loss. For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in-capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded as a liability at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss in the consolidated statements of operations and comprehensive loss.

In connection with the Merger, eligible Legacy Energy Vault stockholders immediately prior to the Closing, have the contingent right to receive an aggregate of 9.0 million shares of the Company’s common stock (“Earn-Out Shares”) upon the Company achieving each Earn-Out Triggering Event (defined below) during the period beginning on the 90th day following the closing of the Merger and ending on the third anniversary of such date. An “Earn-Out Triggering Event” means the date on which the closing price of the Company’s common stock quoted on the NYSE is greater than or equal to certain specified prices for any 20 trading days within a 30 consecutive day trading period.

The Earn-Out Shares were recognized at fair value upon the closing of the Merger and classified in stockholders’ equity. Because the Merger was accounted for as a reverse recapitalization, the issuance of the Earn-Out Shares was treated as a deemed dividend and since the Company does not have retained earnings, the issuance was recorded within additional-paid-in capital (“APIC”) and had a net nil impact on APIC.

The Company issues stock-based compensation awards to employees, directors, and non-employees in the form of stock options and restricted stock units (“RSUs”). The Company measures and recognizes compensation expense for stock-based awards based on the award’s fair value on the date of the grant. The Company accounts for forfeitures of stock-based awards when they occur. The fair value of RSUs that vest based on service conditions is measured using the fair value of the Company’s common stock on the date of the grant. The fair value of RSUs that vest based on market conditions is measured using a Monte Carlo simulation model on the date of the grant. The fair value of stock options that vest based on service conditions is measured using the Black-Scholes option pricing model on the date of the grant. The Monte Carlo simulation model and the Black-Scholes option pricing model require the input of highly subjective assumptions, including the fair value of the Company’s common stock, the expected term of the award, the expected volatility of the Company’s common stock, risk-free interest rates, and the expected dividend yield of the Company’s common stock. This assumption used to determine the fair value of the awards represent management’s best estimates. These estimates involve inherit uncertainties and the application of management’s judgment.

The Company accounts for income taxes in accordance with ASC 740, Income Taxes (“ASC 740”). ASC 740 prescribes the use of the liability method, whereby deferred tax asset and liability account balances are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates that will be in effect when the differences are expected to reverse.

Deferred income tax balances reflect the effects of temporary differences between the carrying amounts of assets and liabilities and their tax bases and are stated at enacted tax rates expected to be in effect when taxes are actually paid or recovered. Deferred tax assets are evaluated for future realization and reduced by a valuation allowance to the extent the Company believes they will not be realized.

Basic net loss per share of common stock is calculated by dividing net loss by the weighted average number of common shares outstanding for the applicable period. Diluted net loss is computed based on the weighted average number of common shares outstanding increased by the number of additional shares that would have been outstanding had the potentially dilutive common shares been issued, including any dilutive effect from outstanding warrants, outstanding stock options, or unvested RSUs, and reduced by the number of shares the Company could have repurchased with the proceeds from the issuance of the potentially dilutive shares. Potentially dilutive instruments are excluded from the per share calculation because the Company is in a net loss position and they would therefore be anti-dilutive.

In May 2024, the Company’s consolidated subsidiary, Cetus Energy, Inc. (“Cetus”), issued a share-based payment award to an employee of Cetus, representing a non-controlling interest. A non-controlling interest in a subsidiary is considered an ownership interest in a majority-owned subsidiary that is not attributable to the parent. The Company includes non-controlling interest as a component of stockholders’ equity on the Company’s consolidated balance sheets. The Company owns 85% of Cetus.

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2023-07, Segment Reporting (Topic 280) — Improvements to Reportable Segment Disclosures. The ASU improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. We adopted this standard effective for the reporting periods noted above, with retrospective application to all prior periods presented in the financial statements. The adoption of this standard did not have any impact on the Company’s financial condition, results of operations and comprehensive loss, or cash flows, but resulted in enhancements to our segment disclosures, primarily related to our significant segment expenses. See Note 17, Segment Reporting, for further information.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topics 740): Improvements to Income Tax Disclosures to expand the disclosure requirements for income taxes. Upon adoption we will be required to disclose additional specified categories in the rate reconciliation in both percentage and dollar amounts. We will also be required to disclose the amount of income taxes paid disaggregated by jurisdiction, among other disclosure requirements. The standard can be applied either prospectively or retrospectively. We will adopt the standard in our 2025 annual period and are currently assessing the effect that the updated standard will have on our financial statement disclosures.

In November 2024, the FASB issued ASU 2024-03, Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (Subtopic 220-40) — Disaggregation of Income Statement Expenses. The ASU requires the disclosure of additional information about specific costs and expense categories in the notes to the consolidated financial statements. The standard is effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted. The standard should be applied on a prospective basis with the option to apply the standard retrospectively. We are currently evaluating the impact of this standard on our disclosures.
