Capstone Green Energy Holdings, Inc.

(Unaudited)

1. Business and Organization

Capstone Green Energy Holdings, Inc. (the “Company”), the public successor to Capstone Green Energy Corporation, together with its consolidated operating subsidiary Capstone Green Energy LLC (the “Operating Subsidiary”) is a provider of customized microgrid solutions, on-site resilient Energy-as-a-Service (“EaaS”) solutions and distributed on-site energy technology systems. The Company provides behind-the-meter microturbine energy solutions for industrial and commercial customers, including applications for data centers, station power, and port operations, focused addressing the “Energy Trilemma” of resiliency, sustainability, and affordability.

The Company’s offerings include stationary distributed power generation and energy distribution solutions, including cogeneration systems such as combined heat and power (“CHP”), integrated combined heat and power (“ICHP”), and combined cooling, heat and power (“CCHP”), as well as solutions for renewable energy, natural resources, and critical power supply applications. The Company’s inverter-based technologies enable operation in parallel with the electric grid or in island mode within localized microgrids.

The Company’s energy conversion products business line is driven by its industry-leading, highly efficient, low-emission and resilient microturbine energy systems, which offer configurations and customer-tailored solutions. Through its EaaS business line, the Company provides build, own, operate and maintain (“BOOM”) and energy rental solutions utilizing its microturbine energy systems.

The Company offers long-term maintenance agreements (LTMAs) that reduce operating risk and provide predictable maintenance costs over the life of the equipment, with flexible access to Original Equipment Manufacturer (“OEM”) parts.

As a result of past delays in filing the Company’s periodic reports with the Securities Exchange Commission (the “SEC”) and the requirements relating to Market Value of Listed Securities (“MVLS”), the Company was unable to comply with the Nasdaq listing standards, and as a result, the Company’s common stock was suspended from trading on the Nasdaq Capital Market effective October 5, 2023 and formally delisted effective October 23, 2023. Following completion of the financial statement restatements for Fiscal 2022 and 2023 and completion of the filings for Fiscal 2024, the Company became current with all periodic filings with the SEC. Effective January 2, 2025, the Company’s common stock began trading on the over-the-counter market (“OTC”). On September 26, 2025, the Company’s common stock was approved for quotation on the OTCQX Best Market, under the symbol “CGEH.”

2. Basis of Presentation, Significant Accounting Policies and Going Concern

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and the instructions to Form 10-Q and Regulation S-X promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). They do not include all of the information and footnotes required by GAAP for complete financial statements. The Condensed Consolidated Balance Sheet as of March 31, 2025, was derived from audited Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2025. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the interim Condensed Consolidated Financial Statements include all adjustments (including normal recurring adjustments) necessary for a fair presentation of the financial condition, results of operations and cash flows for such periods. Results of operations for any interim period are not necessarily indicative of results for any other interim period or for the full year. These Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2025, filed with the SEC on June 27, 2025. This Quarterly Report on Form 10-Q (this “Form 10-Q”) refers to the Company’s fiscal years ending March 31 as its Fiscal years.

Basis for Consolidation The Condensed Consolidated Financial Statements included in this filing include the accounts of the Company, the Operating Subsidiary, Capstone Turbine Financial Services, LLC, its wholly owned

subsidiary formed in October 2015, and Cal Microturbine LLC (“Cal Microturbine”) after elimination of inter-company transactions.

Reclassification Certain items in prior financial statements have been reclassified to conform to the current presentation and provide comparability but have no effect on the reported financial statements.

Significant Accounting Policies Except as described below, there have been no changes to the Company’s significant accounting policies described in the Annual Report on Form 10-K for Fiscal Year 2025 filed with the SEC, that have had a material impact on the Company's Condensed Consolidated Financial Statements. See Note 20 – Business Combinations in the Notes to Condensed Consolidated Financial Statements for information on our acquisition of Cal Microturbine.

Going Concern In connection with the preparation of these Condensed Consolidated Financial Statements for the three and nine months ended December 31, 2025, management evaluated whether there were conditions and events, considered in the aggregate, that raised substantial doubt about the Company’s ability to meet its obligations as they become due over the next twelve months from the date of the issuance of the financial statements. As of December 31, 2025, the Company had cash of$15.2 million, which includes restricted cash of$0.7 million, and a working capital deficit of$22.9 million. The Company had net income of$1.2 million and$1.3 million during the three and nine months ended December 31, 2025, respectively.

The Exit Roll Up Notes will mature on December 7, 2026 (see Note 8 – Debt in the Notes to Condensed Consolidated Financial Statements for further discussion). The Company may not have sufficient internally generated cash and is evaluating options to obtain sufficient financing to satisfy the obligations of the Exit Roll Up Notes. If the Company is unable to repay the obligations of the Exit Roll Up Notes on the maturity date, it will be in default under the Exit Note Purchase Agreement (as defined in Note 8 – Debt), which may result in, among other things, default interest or an acceleration of all obligations. It is not certain whether the Company will have, or will be able to obtain, sufficient funds to make any such accelerated payments. If any outstanding indebtedness under the Exit Note Purchase Agreement is accelerated, the Company’s assets may not be sufficient to repay such indebtedness. The Company and its advisors are considering various alternatives to address the upcoming maturity of the Exit Roll Up Notes, which may include issuances of equity or the incurrence of additional indebtedness; however, there can be no assurance that the Company will be successful in refinancing the Exit Roll Up Notes.

Given the Company’s current cash position, short term debt repayments, limits to accessing capital and debt funding options, and current economic and market risks, there exists substantial doubt regarding the Company’s ability to continue as a going concern and its ability to meet its financial obligations as they become due over the next twelve months from the date of issuance of the financial statements as of, and for the period ended December 31, 2025. See the discussion under “Management’s Discussion and Analysis – Liquidity and Capital Resources” for additional information. The accompanying financial statements have been prepared assuming that the Company will continue as a going concern, and do not include any adjustments that might result from the outcome of this uncertainty.

The Company has developed a plan to improve future financial performance. The plan includes multiple process improvement workstreams intended to drive operational and financial performance. The process improvement initiatives are supported with external resources as needed for a specific level of expertise. The plan includes cost reduction in products, services and operating expenses, additional margin expansion through price increases, and sales volume initiatives focused on improving the Company’s liquidity. Achieving the targeted product cost reductions has risk, and is being challenged by the current geopolitical environment, including the impact of tariffs. There is no guarantee that such steps will be successful or result in our ability to meet our payment obligations coming due within the twelve-month period after the date of this report.

3. Recently Issued Accounting Pronouncements

Not Yet Adopted

In December 2023, the FASB issued ASU No. 2023-09,Income Taxes: Improvements to Income Tax Disclosures(Topic 740), which requires that an entity, on an annual basis, disclose additional income tax information, primarily related to the rate reconciliation and income taxes paid.

We are evaluating the impact of the standard on the consolidated financial statements.

4. Customer Concentrations and Accounts Receivable

Accounts receivables are presented on the Condensed Consolidated Balance Sheets, net of estimated credit losses. The Company applies the aging method by pooling receivables based on levels of delinquency and applying historical loss rates on what has been historically uncollectible by aging categories. The historical loss rate is adjusted for current conditions and reasonable and supportable forecasts of future losses, as necessary. Additionally, the allowance for credit loss calculation includes subjective adjustments for qualitative risk* *factors that could likely cause estimated credit losses to differ from historical experience. The factors include assessments of various economic conditions, significant events that have or will occur, geographic location, size and credit ratings of the customers. The Company may also record a specific reserve for individual accounts when the Company becomes aware of specific customer circumstances, such as in the case of a bankruptcy filing or deterioration in the customer’s operating results or financial position. Accounts deemed uncollectible are written off against the allowance for credit loss.

Changes in the current expected credit losses (“CECL”) allowance for accounts receivable are as follows (in thousands):

Sales to DTC Soluciones (“DTC”), one of the Company’sdistributors, accounted for 27% of revenue for the three months ended December 31, 2025. Sales to E-Finity Distributed Generation (“E-Finity”), Lone Star Power Solutions, LLC (“Lone Star”) and Cal Microturbine, LLC (“Cal Microturbine”), three of the Company’s distributors, accounted for 15%,14% and 11% of revenue for the three months ended December 31, 2024, respectively. Sales to Cal Microturbine, E-Finity, DTC and Lone Star, four of the Company’s distributors, accounted for 20%,17%,12% and 10% of revenue for the nine months ended December 31, 2025, respectively. On August 13, 2025, the Company completed its acquisition of Cal Microturbine. Refer to Note 20— Business Combination for further details. E-Finity and Lone Star, twoof the Company’s distributors, accounted for 16% and 13% of revenue for the nine months ended December 31, 2024, respectively.

Additionally, Supernova Energy Services SAS and RSP Systems, two of the Company’s distributors, accounted for 16% and 11% of accounts receivable as of December 31, 2025, respectively. Lone Star and Optimal Group Australia accounted for 18% and 10% of accounts receivable as of March 31, 2025, respectively. The Company recorded a credit loss expense ofzero and $0.2 million during the three months ended December 31, 2025 and 2024, respectively. The Company recorded a credit loss expense of $0.4 million and $0.6 million during the nine months ended December 31, 2025 and 2024, respectively.

5. Inventories

Inventories are valued at the lower of cost (determined on a first-in, first-out (“FIFO”) basis) or net realizable value and consisted of the following (in thousands):

The non-current portion of inventories represents that portion of inventories in excess of amounts expected to be sold or used in the next twelve months. The non-current inventories are primarily comprised of parts for older generation products that are still in operation but are not technologically compatible with current configurations. The Company expects to use the non-current portion of the inventories on hand as of December 31, 2025 over the periods presented in the following table (in thousands):

6. Property, Plant, Equipment and Rental Assets

Property, plant, equipment and rental assets consisted of the following (in thousands):

The Company regularly assesses the useful lives of property and equipment and retires assets no longer in service. Depreciation expense for property, plant, equipment and rental assets was $1.0 million and $0.9 million for the three months ended December 31, 2025 and 2024, respectively. The depreciation expense was $2.9 million and $3.0 million for the nine months ended December 31, 2025 and 2024, respectively.

7. Accrued Warranty Reserve

The Company provides for the estimated costs of warranties at the time revenue is recognized. The specific terms and conditions of those warranties vary depending upon the microturbine product sold and the geography of sale. The Company’s product warranties generally start from the delivery date and continue for up totwenty-four months. Factors that affect the Company’s warranty obligation include product failure rates, anticipated hours of product operations and costs of repair or replacement in correcting product failures. These factors are estimates that may change based on new information that becomes available each period. Similarly, the Company also accrues the estimated costs to address reliability repairs on products no longer in warranty when, in the Company’s judgment, and in accordance with a specific plan developed by the Company, it is prudent to provide such repairs. The Company assesses the adequacy of recorded warranty liabilities quarterly and adjusts to the liability, as necessary. When the Company has sufficient evidence that product changes are altering the historical failure occurrence rates, the impact of such changes is incorporated in estimating future warranty liabilities.

Changes in the accrued warranty reserve consisted of the following (in thousands):

8. Debt

Exit Note Purchase Agreement

The Company entered into an exit facility on December 7, 2023 (the “Exit Note Purchase Agreement”), for an aggregated principal amount of $28.1 million, consisting of $21.1 million of Exit Roll Up Notes, including accrued and unpaid interest and commitment fees and $7.0 million of Exit New Money Notes (together the “Exit Notes”) subject to the terms and conditions set forth in the Exit Note Purchase Agreement by and among Operating Subsidiary, as the issuer, the Company and Capstone Financial Services, as the guarantors (the “Guarantors”), Broad Street Credit Holdings LLC (the “Purchaser”) and Goldman Sachs Specialty Lending Holdings, Inc. (the “Collateral Agent”).

The Exit Note Purchase Agreement also provides for a $10.0 million uncommitted incremental facility. The proceeds from the fully drawn $7.0 million of Exit New Money Notes were used to fund restructuring expenses and for working capital and general corporate purposes. The Exit Notes bear interest at a rate equal to the Adjusted Term SOFR (as defined in the Exit Note Purchase Agreement) plus 7.00% per annum. A portion of the interest on the Exit Notes was paid-in-kind until the third year following December 7, 2023.

The Exit Roll Up Notes mature on December 7, 2026, and the Exit New Money Notes matured on December 7, 2025.

The scheduled maturities of the Company’s debt are as follows as of December 31, 2025:

The Exit Notes issued pursuant to the Exit Note Purchase Agreement are secured by a lien on substantially all of the property and assets of the Operating Subsidiary and each Guarantor, subject to customary exceptions and exclusions. The Exit Note Purchase Agreement also includes conditions precedent, representations and warranties, affirmative and negative covenants, events of default, and other customary provisions, including financial covenants with respect to minimum consolidated liquidity and minimum consolidated adjusted EBITDA.

If defaults occur, the Purchaser and the Collateral Agent can exercise their rights and remedies under the Exit Note Purchase Agreement (and other security-related documents), including a right to accelerate the maturity of the Company’s repayment obligations under the Exit Roll Up Notes. The Company has the right to cure an event of default for a breach of the consolidated adjusted EBITDA covenant with a prepayment on the Exit Roll Up Notes up to the amount that is required to achieve the minimum consolidated adjusted EBITDA covenant for the quarter. In the event the Company does not cure the breach, the requisite Purchaser may cause the Collateral Agent to enforce any and all liens and security interests created pursuant to the Collateral Documents and may enforce any and all rights and remedies available. The Company believes it is probable the consolidated liquidity and consolidated adjusted EBITDA financial covenants discussed below will be satisfied for all measurement dates in the upcoming 12 months.

On June 28, 2024, the Company entered into the First Amendment (the “First Amendment”) to the Exit Note Purchase Agreement. The First Amendment provides for: (i) the amendment of the minimum consolidated adjusted

EBITDA financial covenant to (a) allow adjustment for costs related to the restatement of, or other adjustments to, the financial statements of the Company for the period beginning on the Closing Date (as defined in the Exit Note Purchase Agreement) and ending at the end of the 2025 Fiscal Year and (b) the minimum consolidated adjusted EBITDA financial covenant to be first tested at the quarter ended September 30, 2024, (ii) the amendment of the minimum consolidated liquidity financial covenant to (a) reduce the minimum consolidated liquidity to $1,000,000 from September 30, 2024 to March 30, 2025 and (b) defer the testing of the minimum consolidated liquidity financial covenant to September 30, 2024 and (iii) the extension of the deadline for the delivery of the Company’s audited financial statements for the fiscal year ended March 31, 2024 (the “Fiscal 2024 Financial Statements”) to September 27, 2024 and the removal of the covenant that the Fiscal 2024 Financial Statements be accompanied by a report and opinion of an independent certified public accountant which is not subject to any “going concern” or like qualification.

The minimum consolidated liquidity covenant will be tested at all times from and after September 30, 2024, and requires the Company and its subsidiaries to maintain a minimum average Consolidated Liquidity (as defined in the First Amendment) during anyseven consecutive day period of no less than:

(i) from September 30, 2024 to March 30, 2025, $1,000,000;

(ii) from March 31, 2025 to July 30, 2025, $2,500,000;*

(iii) from July 31, 2025 to September 29, 2025, $3,000,000;*

(iv) from September 30, 2025 to March 30, 2026, $3,500,000; and

(v) from March 31, 2026 to December 7, 2026, $4,000,000.

*On June 23, 2025 the Company received an additional waiver to defer the minimum liquidity increase from $2.5 million to $3.0 million from June 30, 2025 to July, 31, 2025.

The minimum consolidated adjusted EBITDA covenant will be tested on the last day of each fiscal quarter, commencing with September 30, 2024, and will require the Company and its subsidiaries to maintain a minimum consolidated adjusted EBITDA (as defined in the First Amendment) as atthe end of any fiscal quarter (i) from the Closing Date until September 30, 2024, for the period of the fiscal quarters then ended in such calendar year and (ii) from October 1, 2024, for the four fiscal quarter period then ended, to not be less than the correlative amount indicated below (with corresponding calendar quarters also included as reference):

On August 13, 2025, the Company entered into the Consent to Cal Micro Acquisition and Second Amendment (the “Consent and Second Amendment”) to the Note Purchase Agreement, dated December 7, 2023 (as amended, the “NPA”), by and among Capstone Green Energy LLC, a Delaware limited liability company (the “Buyer”), the Company and Capstone Turbine Financial Services, LLC, a Delaware limited liability company, as guarantors, Goldman Sachs Specialty Lending Group, L.P., a Delaware limited partnership, as collateral agent for the purchasers from time to time party thereto and Capstone Distributor Support Services Corporation, a Delaware corporation, as Purchaser. (as defined in the NPA, as amended by the Consent and Second Amendment).

As of December 31, 2025, the Company has an outstanding Exit Roll Up Notes balance of $25.3 million, comprised of $21.1 million of principal and $4.3 million of total PIK interest, less debt issuance costs of $0.1 million. Debt issuance costs in relation to the Exit New Money Notes and the Exit Roll Up Notes are being amortized over the term at an effective interest rate of 11.31% as of December 31, 2025. In December 2025, the Company repaid the Exit New Money Notes in full, including $7.0 million in principal and $1.3 million of associated interest. As of December 31, 2025, the Company was in compliance with all financial covenants. The Company incurred total cash interest expense

on the debt during the three months and nine months ended December 31, 2025 of approximately $0.5 million and $1.0 million, respectively. The Company didnot incur any cash interest expense on the debt during the three and nine months ended December 31, 2024.

9. Leases

Lessor

The Company rents microturbine equipment to its customers for terms ranging from a couple of months to up toninety-six months with most of the leases generally with thirty-six month terms with anextension option, which may impact the lease term. The leases may provide the lessee with the option to purchase the underlying assets at the end of the lease term. Monthly rental payments are fixed; however, the leases may include variable payments for fuel, excess labor, additional equipment, or technician labor and engineering support. The leases are classified as either sales-type leases or operating leases, as appropriate. As further described below, the Company rents certain microturbine equipment back from customers and subleases this equipment to end users as a part of its Energy-as-a-Service business.

At December 31, 2025, the Company’s minimum rental revenue to be received was as follows (in thousands):

At December 31, 2025, the Company’s future scheduled minimum payments to be received from its sales-type lease was as follows (in thousands):

The Company recognized less than $0.1 million of interest income related to lease receivables during the three and nine months ended December 31, 2025. There wasno interest income related to lease receivables during the three and nine months ended December 31, 2024.

Lessee

The Company leases facilities and equipment under various non-cancelable operating and finance leases expiring at various times through Fiscal 2029. All of the leases require the Company to pay maintenance, insurance and property taxes. The lease agreements for primary office and manufacturing facilities provide for rent escalation over the lease term andrenewal options forfive-year periods. Lease expense is recognized on a straight-line basis over the term of the lease, which may include extension periods.

During the nine months ended December 31, 2025, the Company didnot enter into new rental agreements to rent used microturbine equipment from customers where that equipment was not currently in use. The Company may enter into lease modifications from time to time, and the Company modified four of their current lease agreements during the nine months ended December 31, 2025. The existing rental agreements provide the Company an option to extend the lease, however, the Company is not likely to exercise these options and therefore they are not included in the determination of the lease term. As of December 31, 2025, lease commitments totaled approximately 19.0 megawatts of microturbines and had an average term of 33 months and a total remaining commitment value of approximately $6.8 million.

The components of lease expense were as follows (in thousands):

10. Revenue Recognition

The Company derives its revenues primarily from the sale of microturbine products, accessories, parts, equipment rentals and services.

The Company determines revenue recognition through the following steps:

Microturbine Products The Company recognizes revenue when the performance obligation identified under the terms of the contract with its customer is satisfied, which generally occurs, for microturbine products, upon the transfer of control in accordance with the contractual terms and conditions of the sale. The majority of the Company’s revenue associated with a microturbine product is recognized at a point in time when the microturbine product is shipped to the customer. On occasion, the Company enters into bill-and-hold arrangements. Each bill-and-hold arrangement is reviewed and revenue is recognized only when certain criteria have been met: (i) the reason for the bill-and-hold arrangement is substantive; (ii) the product is segregated from the Company’s other inventory items held for sale; (iii) the product is ready for shipment to the customer; and (iv) the Company does not have the ability to use the product or direct it to another customer.

Advanced payments in the form of customer deposits are received on these contracts, typically providing for a substantial portion of the contract value to be paid prior to shipment. Advance payments are not considered a significant financing component as they are typically received less than one year before the related performance obligations are satisfied. Payment terms in contracts with customers typically are 30 or 60 days. The Company extends payment terms past 60 days only on a limited basis, and thus any financing component is not considered material.

Accessories and Parts The Company recognizes revenue when performance obligations identified under the terms of contracts with its customers are satisfied, which generally occurs, for accessories and parts, upon the transfer of control in accordance with the contractual terms and conditions of the sale. The revenue associated with accessories and parts is recognized at a point in time when the material is shipped to the customer.

Warranty Services Revenue from extended warranties is recognized when or as the obligations are satisfied. There are two types of warranties: standard (assurance) and extended warranties. Standard warranties do not represent separate performance obligations but are reflected as a liability associated with the purchase of the product. Extended warranties are separate offerings typically for 12-,24- or 36-month periods beyond the standard warranty that are separate performance obligations recognized as an over-time performance obligation based on the extended warranty period. The Company records amounts billed to customers for reimbursement of shipping and handling costs within revenue. Shipping and handling costs associated with outbound freight after control over a system has transferred to a customer are accounted for as fulfillment costs and are included in cost of goods sold. Sales taxes and other usage-based taxes are excluded from revenue.

Factory Protection Plan (“FPP”), Long Term Maintenance Agreements and Service Cost Reimbursement In addition to the provision of standard warranties, the Company is replacing the FPP with Long Term Maintenance Agreements (“LTMA”), Similar to the FPP, the LTMA are intended to minimize product downtime and control maintenance costs to ensure the microturbine system will operate when needed and perform as intended at the lowest cost of ownership. Revenue related to the Company’s performance obligation to provide replacement parts as needed is recognized over the term of the LTMA contract, intervals aligned to the monthly service period for that customer. LTMA contracts typically range from four years totwelve years and may be cancelled at any time. The related costs for LTMA contracts become the Company’s obligation and are accrued at the time a customer submits a claim, and the claim’s compliance with the terms of the plan are confirmed. The accrual reflects the Company’s best estimate of the probable liability under the replacement part obligation based on actual experience. The LTMA contract offers flexible options for customers, as it can either begin while the system is still covered under the standard warranty or commence once the standard warranty period has expired. The LTMA includes an annual escalator, covers critical components only such as the engine, fuel and electronic components, and excludes freight cost. LTMA contracts do not include labor reimbursement.

Comprehensive FPP and LTMA service contracts require payment at the beginning of the contract period. Advance payments are not considered a significant financing component as they are typically received less than one year before the related performance obligations are satisfied. These payments are a contract liability and are classified as deferred revenue in the Condensed Consolidated Balance Sheets. The performance obligation is fulfilled as the control passes to the customer through the passage of time and recognition of deferred revenue from the FPP or LTMA contracts is recognized in the Condensed Consolidated Statement of Operations. The deferred revenue relating to the annual maintenance service contracts is recognized in the Condensed Consolidated Statement of Operations on a straight-line basis over the expected term of the contract.

The remaining FPP contracts may include labor reimbursement on the labor performed on a microturbine system. Due to the nature of the arrangement, labor reimbursements are accounted for under Accounting Standard Codification (“ASC”) 460 and are recognized as contra revenue as consideration paid to a customer under ASC 606. An Authorized Service Provider (“ASP”) must perform the labor. ASPs submit claims for labor reimbursements and are credited for the cost of labor if the repairs meet the Company’s prescribed standards. The Company is unable to develop a reasonable estimate of the maximum potential payout under these arrangements because the FPP contracts do not contain a limit on the number of labor reimbursements that may be submitted. However, given historical practice, the Company has priced the FPP to cover all costs incurred related to the labor reimbursement and is not exposed to significant losses over the FPP premium.

The labor reimbursement is separate and distinct from the parts offering; therefore, the Company allocates a portion of the transaction price to the labor reimbursement based on a relative standalone selling price (“SSP”). The Company applies judgment in determining the SSP as the labor reimbursement is not sold separately. The Company will recognize a liability at the inception of the executed FPP agreement for the premium received in advance for the Labor offering. Income will be recognized on a net, straight-line basis with labor reimbursement costs recognized when incurred.

Rentals The Company accounts for leases to customers in accordance with lessor accounting under ASC 842. The Company utilizes a portfolio approach by grouping together many similar assets being leased to a single customer. Leases are classified as either sales-type leases or operating leases. The Company’s leases are classified as a sale-type lease if one of the five criteria per the guidance are met. Other leases are classified as operating leases.

For sales-type leases, upon lease commencement, the Company records and presents as a separate line item in the Condensed Consolidated Balance Sheets, the present value of the lease payments as a lease receivable, along with the residual asset discounted using the rate implicit in the lease. Revenue is recognized on the Condensed Consolidated Statements of Operations in the amount of the lease receivable as part of Product and Accessories revenue and the cost of sales in the amount of the carrying value of the underlying asset less the unguaranteed residual asset. The Company believes this is generally more aligned to its current presentation of product sales. After the commencement date, the Company recognizes the imputed interest income as part of the net sales using the effective interest method.

For operating leases, the Company recognizes the underlying assets as rental lease assets. The asset is depreciated on a straight-line basis to its estimated residual value over the estimated useful life. The lease payments are recognized over the lease term on a straight-line basis as part of Rental Revenue.

Contracts with Multiple Performance Obligations

The Company enters into contracts with its customers that often include promises to transfer multiple products, parts, accessories and services. A performance obligation is a promise in a contract with a customer to transfer products or services that are distinct. Determining whether products and services are distinct performance obligations that should be accounted for separately or combined as one unit of accounting may require significant judgment.

Products, parts and accessories are distinct as such services are often sold separately. In determining whether FPP and LTMA service contracts are distinct, the Company considers the following factors for each services agreement: availability of the services from other vendors, the nature of the services, the timing of when the services contract was signed in comparison to the product delivery date and the contractual dependence of the product on the customer’s satisfaction with the professional services work. To date, the Company has concluded that all of the service contracts included in contracts with multiple performance obligations are distinct.

The Company allocates the transaction price to each performance obligation on a SSP basis. The SSP is the price at which the Company would sell a promised product or service separately to a customer. Judgment is required to determine the SSP for each distinct performance obligation.

The Company determines SSP by considering its overall pricing objectives and market conditions. Significant pricing practices taken into consideration include the Company’s discounting practices, the size and volume of the Company’s transactions, the customer demographic, the geographic area where systems and services are sold, price lists, its go-to-market strategy, historical sales and contract prices. The determination of SSP is made through consultation with and approval by the Company’s management, taking into consideration the go-to-market strategy. As the Company’s go-to-market strategies evolve, the Company may modify its pricing practices in the future, which could result in changes to SSP.

In certain cases, the Company may be able to establish SSP based on observable prices of products or services sold separately in comparable circumstances to similar customers. The Company uses a single amount to estimate SSP when it has observable prices.

If SSP is not directly observable, for example when pricing is highly variable, the Company may use a range of SSP. The Company determines the SSP range using information that may include market conditions or other observable inputs. The Company typically has more than one SSP for individual products and services due to the stratification of those products and services by customer size and geography.

Contract Balances

The Company’s deferred revenues consist of deposits and advance payments for microturbine products, parts, accessories and parts ordered under sales contracts, which have not yet been delivered (contract liabilities), as well as advance payments on service obligations, FPP contracts and extended warranties. Deposits are primarily non-refundable cash payments from distributors for future orders. The current portion of deferred revenue and the non-current portion of deferred revenue are included in the Current Liabilities and Long-Term Liabilities, respectively, in the Condensed Consolidated Balance Sheets.

Changes in deferred revenue consisted of the following (in thousands):

Deferred revenue attributed to FPP and LTMA contracts represents the unearned portion of the Company’s contracts. FPP contracts are generally paid quarterly in advance, with revenue recognized on a straight-line basis over the contract period. As of December 31, 2025, approximately $4.9 million of revenue is expected to be recognized from the remaining contract liability for FPP contracts. The Company expects to recognize revenue on approximately $4.2 million of these unfulfilled performance obligations over the next 12 months and the balance of $0.7 million will be recognized thereafter.

Unsatisfied Performance Obligations

The Company has elected the practical expedient to disclose only the value of unsatisfied performance obligations for contracts with an original expected length greater thanone year. The majority of the Company’s product sales have relatively short periods of manufacture and result in fulfillment (lead times) of less than one year after manufacture and delivery and thus are excluded from this disclosure.

Our service contracts have periods of greater than one year in duration, however they are cancellable without any significant penalty, therefore the enforceable duration of these contracts is considered to be one year or less and thus under the practical expedients they are also excluded from this disclosure.

Practical Expedients

The Company applies the practical expedient for contracts ofone year or less in duration for the direct and incremental costs to obtain a contract to expense such costs as incurred. Contracts are considered to be the individual sales orders received from the distributors and as per above, such orders are typically fulfilled in less than one year. These costs are recorded within sales and marketing expenses in the accompanying Condensed Consolidated Statements of Operations.

Warranty The Company provides for the estimated costs of warranties at the time revenue is recognized under ASC 450. The specific terms and conditions of those warranties vary depending upon the microturbine product sold and the geography of sale. The Company’s product warranties generally start from the delivery date and continue for up totwenty-four months. Factors that affect the Company’s warranty obligation include product failure rates, anticipated hours of product operations and costs of repair or replacement in correcting product failures. These factors are estimates that may change based on new information that becomes available each period. Similarly, the Company also accrues the estimated costs to address reliability repairs on products no longer in warranty when, in the Company’s judgment, and in accordance with a specific plan developed by the Company, it is prudent to provide such repairs. The Company assesses the adequacy of recorded warranty liabilities quarterly and adjusts the liability as necessary. When the Company has sufficient evidence that product changes are altering the historical failure occurrence rates, the impact of such changes is then taken into account in estimating future warranty liabilities.

Research and Development (“R&D”) The Company accounts for grant distributions and development funding as offsets to R&D expenses and both are recorded as the related costs are incurred in the Company’s statement of operations. There were no offsets to R&D during Fiscal 2026 and 2025.

11. Temporary Equity

Redeemable Preferred Units

Redeemable noncontrolling interests are reported on the Condensed Consolidated Balance Sheet as Temporary Equity.

On December 7, 2023, in connection with the reorganization, the Operating Subsidiary issued 10,449,863 Series A Redeemable Preferred Units (the “Preferred Units”) that include a redemption feature. The Preferred Units have an aggregate value representing 37.5% equity ownership in the Operating Subsidiary (“Aggregate Purchase Price”). At any time during the six-month period following December 7, 2029, the holders of the Preferred Units may elect to have all, but not less than all, of the then outstanding Preferred Units redeemed. Therefore, the Preferred Units are probable of becoming redeemable and are classified as temporary (‘mezzanine’) equity.

The Preferred Units also provide the holder with the option to convert all or less than all of the Preferred Units into Operating Subsidiary Common Units (“Common Units”) at any time and from time to time without the payment of additional consideration. If the holder elects to convert the Preferred Units, the specified number of Preferred Units to be converted will be divided by the total number of Preferred Units then outstanding times 37.5% of the Common Units deemed outstanding. To the extent some, but not all of the Preferred Units are converted, the 37.5% percentage will be proportionately reduced, and the same adjustment will apply for purposes of calculating other as-converted entitlements of the Preferred Units. None of the Preferred Units had been converted into Common Units as of December 31, 2025.

Additionally, the Preferred Units provide the holder with a put option to sell the shares to the Operating Subsidiary and the liquidation preference provides the holder with the option to exchange the Preferred Units for cash.

Management’s initial valuation of the Preferred Units was made under ASC Topic 480, Distinguishing Liabilities from Equity, and is specifically determined by the ‘redemption value’. This initial value was established using a fair value methodology, to establish the initial redemption value per the terms of the Capstone Green Energy LLC Agreement. The initial fair value of $1.33 per Preferred Unit was determined through the use of an option-pricing method (“OPM”) that treats the common and preferred units as call options on the enterprise value of the Company with exercise prices based on the liquidation preference of the preferred units. The OPM incorporated multiple thresholds that represent future change of control sale prices where the payout structure would differ based on the rights and preferences of each share class. The OPM used was the Black-Scholes Metron (“BSM”) model to price the call option. The enterprise value utilized by the Company in the OPM represents the value agreed upon by the parties involved in our restructuring as approved by the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”).

Subsequent measurement under ASC Topic 480, Distinguishing Liabilities from Equity, for the redemption value follows the definition of redemption value as per the Capstone Green Energy LLC Agreement, which has been defined as the greater of 1) the share price of CGEH shares (if CGEH is publicly traded), with appropriate adjustments for customary and appropriate factors, or 2) the Aggregate Purchase Price plus declared but unpaid dividends, the ‘maximum redemption value’. The subsequent measurement based on the redemption value method should not result in an amount that is less than the initial recorded value of $13.9 million.

For the three and nine months ended December 31, 2025, the Company’s Common Stock is publicly trading and the Preferred Units are not currently redeemable. The Company will measure the maximum redemption value at the end of each accounting period, which is based on the Company’s Common Stock value at period end. The closing value of CGEH stock was $5.04 and $0.75 as of December 31, 2025, and March 31, 2025, respectively.

At each reporting period, the Company remeasures the redemption value of the Preferred Units and adjusts the carrying value, if that value exceeds the initial fair value, to equal the maximum redemption value to retained earnings and additional-paid-in-capital. The initial fair value measurement was $13.9 million. Subsequent remeasurement of the Preferred Units to the maximum redemption value for this reporting period has exceeded the initial fair value. As of December 31, 2025, the Preferred Units have been adjusted to their maximum redemption value of $70.9 million.

12. Private Investment in Public Equity (“PIPE”) Financing

Overview

On November 24, 2025, the Company entered into a Securities Purchase Agreement with certain accredited investors pursuant to which the Company agreed to issue and sell (i)3,980,000 shares of its common stock at a purchase price of $2.00 per share and (ii)3,520,000 pre-funded warrants to purchase shares of common stock at a purchase price per pre-funded warrant equal to the common stock purchase price minus $0.001. The pre-funded warrants have an exercise price of $0.001 per share. The transaction closed on November 25, 2025, and generated gross proceeds of approximately $15.0 million before deducting placement agent fees and other offering costs. At December 31, 2025, all of the 3,520,000 pre-funded warrants remained outstanding.

The Company paid the placement agent a cash fee of 7.0% of the gross proceeds received from investors that were not directors or executive officers of the Company and reimbursed up to $100,000 of legal and out-of-pocket expenses, resulting in total offering costs of approximately $1.2 million, which were recorded as a reduction of additional paid-in capital in accordance with ASC Topic 505, Accounting for Distributions to Shareholders with Components of Stock and Cash. Net proceeds from the offering were approximately $13.8 million. The Company used approximately $8.3 million of the net proceeds to repay outstanding indebtedness maturing December 7, 2025, and intends to use the remaining proceeds for working capital and general corporate purposes.

Pre-Funded Warrants

Each pre-funded warrant is exercisable at any time after the issuance date and until exercised in full, subject to certain beneficial ownership limitations that restrict the holder from exercising the warrant if such exercise would result in the holder beneficially owning more than 4.99% (or, at the holder’s election, up to 9.99% after 61 days’ notice) of the Company’s outstanding common stock. The pre-funded warrants are exercisable into a fixed number of shares for a fixed exercise price and do not contain cash settlement features outside the Company’s control. Accordingly, the pre-funded warrants were classified in equity in accordance with ASC Topic 480, Distinguishing Liabilities from Equity and ASC Topic 815 Derivatives and Hedging. The proceeds allocated to the pre-funded warrants were recorded in additional paid-in capital.

Registration Rights

In connection with the offering, the Company entered into a Registration Rights Agreement requiring it to file a resale registration statement covering the shares and the shares underlying the pre-funded warrants within 30 days after the signing date and to use commercially reasonable efforts to cause the registration statement to become effective within specified timeframes. The Registration Rights Agreement does not require cash penalties for failure to meet the filing or effectiveness deadlines; therefore, no liability was recorded in connection with these obligations. As of December 31, 2025, the registration statement has been filed.

13. Net Income (Loss) Per Common Share

The Company has common and non-voting common stock outstanding. The non-voting common stock has the same economic rights as the common stock; therefore, earnings per share is presented on a combined basis. Basic income (loss) available to stock holders is computed using the weighted-average number of common shares and non-voting common shares outstanding for the period. Diluted income (loss) per share is computed without consideration of potentially dilutive common stock equivalents such as stock options, restricted stock units and warrants if the Company produced a loss, as the effect would have been anti-dilutive. In addition, the change in the carrying value of the Preferred Units is excluded from the calculation of diluted earnings per share. For the three and nine months ended December 31,

2025 and 2024, there was no difference in the number of shares used to calculate basic and diluted shares outstanding due to the Company’s net loss available to stockholders.

The Company didnot have any outstanding stock options as of December 31, 2025. As of December 31 2025, the Company adjusted the carrying value of the Preferred Units as discussed in Note 11— Temporary Equity above.

14. Stock Compensation

The following table summarizes, by Condensed Consolidated Statements of Operations line item, stock-based compensation expense (in thousands). The Company recognized $10 thousand of additional paid in capital related to stock compensation for Capstone Distributor Support Services Corporation (“CDSSC”) employees and is not included in the Company’s Condensed Consolidated Statement of Operations.

15. Fair Value Measurements

The FASB has established a framework for measuring fair value using GAAP. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy are described as follows:

Level 1. Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets.

Level 2. Inputs to the valuation methodology include:

If the asset or liability has a specified (contractual) term, the level 2 input must be observable for substantially the full term of the asset or liability.

Level 3. Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The asset or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used must maximize the use of observable inputs and minimize the use of unobservable inputs.

Basis for Valuation

The carrying values reported in the Condensed Consolidated Balance Sheets for cash, accounts receivable, accounts payable approximate their fair values because of the immediate or short-term maturities of these financial instruments. Financial and non-financial assets and liabilities measured on a recurring basis are those that are adjusted to fair value at each reporting period and include the Company’s Preferred Units. The Company used the BSM model (Level 3) with standard valuation inputs to initially value the Preferred Units on December 7, 2023. Refer to Note 11— Temporary Equity.

16. Employee Benefit Plans

The Company maintains a defined contribution 401(k) profit-sharing plan in which all employees are eligible to participate. Employees may contribute up to Internal Revenue Service annual limits or, if less,90% of their eligible compensation. Employees are fully vested in their contributions to the plan. The plan also provides for both Company matching and discretionary contributions, which are determined by the Board. The Company has been matching 50 cents on the dollar up to 6% of the employees’ contributions since February 2019. Prior to that date, the Company had been matching 50 cents on the dollar up to 4% of the employees’ contributions since October 2006. There wereno Company

contributions to the plan prior to October 2006. The Company’s match vests 25% a year over four years starting from the employee’s hire date. The Company recorded expense of approximately $0.1 million for the three months ended December 31, 2025 and 2024. The Company recorded expense of approximately $0.2 million for the nine months ended December 31, 2025 and 2024.

17. Balance Sheet Information

Prepaid Expenses and Other Assets

As of December 31, 2025, the Company had $2.1 million of royalty-related assets remaining recorded within the “Prepaid expenses and other current assets” line item on the accompanying Condensed Consolidated Balance Sheets. The assets are being amortized over a 15-year period through September 2033 using an effective royalty rate.

A 15-year amortization period is the minimum expected life cycle of the current generation of products. The effective royalty rate is calculated as the prepaid royalty settlement divided by total projected microturbine system units over the 15-year amortization period. On a quarterly basis, the Company performs a re-forecast of microturbine system unit shipments to determine if an adjustment to the effective royalty rate is necessary and accordingly whether an impairment exists. The Company determined an impairment didnot exist as of December 31, 2025, or March 31, 2025.

The current and long-term portions of prepaid royalties and prepaid and other assets were as follows (in thousands):

18. Commitments and Contingencies

Purchase Commitments

As of December 31, 2025, the Company had firm commitments to purchase inventories of approximately $41.3 million through Fiscal 2027. Certain inventory delivery dates and related payments are not scheduled; therefore, amounts under these firm purchase commitments will be payable upon the receipt of the related inventory.

While the Company has never incurred costs or

obligations for these types of replacements, it is possible that future changes in the Company’s product technology could result in and yield costs to the Company if significant amounts of inventory are held at distributors. As of December 31, 2025, no significant inventories of this nature were held at distributors.

Legal Matters

Cal Microturbine Arbitration

On March 13, 2024, Cal Microturbine, a current distributor of the Company, filed a complaint before the American Arbitration Association, seeking approximately $24.5 million in damages and alleging that the Company breached the Distributor Agreement between the parties and committed fraud by allowing another company, to sell, rent and service turbines in Cal Microturbine’s exclusive territory. On August 18, 2024, Cal Microturbine amended its complaint and reduced its damages claim to $18.8 million. On September 9, 2024, the Company filed a counterclaim against Cal Microturbine for $20.0 million, alleging various violations of the Distributor Agreement. On September 27, 2024, Cal Microturbine provided the second amendment to its complaint and increased its damages to $25.0 million. In February 2025, Cal Microturbine filed an action in California state court seeking a temporary restraining order (“TRO”) to preclude the Company from terminating the Distributor Agreement. Thereafter Cal Microturbine agreed to withdraw the arbitration and dismiss the California state court case with prejudice and without an award of any damages. Cal Microturbine filed a request to dismiss the California state case on August 19, 2025. The arbitration was closed on August 28, 2025.

Spitzer v. Flexon, Jamison, Juric, Robinson, and Hencken

On October 13, 2023, a putative securities class action was filed in the U.S. District Court for the Central District of California, captioned Spitzer v. Flexon, et al., Case No. 2:23-cv-08659, naming certain of the Company’s current and former directors and officers as defendants. The suit alleges various claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, and Rule 10b-5 based on allegedly false and misleading statements and allegedly inadequate disclosure regarding the Company’s business, operations and prospects and the circumstances leading up to the restatement of the Company’s quarterly and annual financial statements. The suit is purportedly brought on behalf of persons and entities that purchased or otherwise acquired the Company’s securities between June 14, 2021, and September 22, 2023, and seeks to recover unspecified compensatory damages and other relief, including attorney’s fees. The Company is not a named respondent in this matter and has not engaged legal counsel.

The parties reached agreement on a settlement amount and on April 4, 2025, the parties filed an unopposed motion for the court to approve settlement and notice procedures. A preliminary hearing date was held on June 5, 2025, and the settlement was approved at a final settlement hearing held on November 24, 2025. The settlement became final on December 24, 2025 with no additional appeals filed. Expenses up to the $1.3 million insurance deductible amount have either been incurred or accrued.

Mark Estrada and Ricardo Montalvo, vs. Capstone Green Energy LLC and Erick Kim

In August 2024, two filings were made by lawyers on behalf of current and former non-exempt Capstone employees against Capstone and one supervisory employee. Both filings allege various pay violations. The first action, filed with the Superior Court of the State of California, requested that the Court certify the employees as a Class. Capstone has arbitration agreements in place with those current and former employees, agreements which include a class action waiver. Accordingly, Capstone moved that the Court compel arbitration, which Plaintiffs opposed. At a hearing in January 2025, the Court determined that the arbitration agreements were enforceable. Then in April 2025, the Court determined that the employees were not entitled to exemption from the enforcement of the arbitration agreements under the Federal Arbitration Act. The Court ordered the plaintiffs to arbitration. To date, the plaintiffs have not filed their claims in arbitration. The action is stayed until the plaintiffs file and complete arbitration.

Plaintiffs filed a separate action asserting the same claims under the Private Attorney General Act with the Superior Court of the State of California on September 22, 2025. The Company has been served with a copy of the complaint on October 13, 2025. The Company will seek to have this action stayed as well in accordance with the Court’s April 2025 ruling compelling the Class action to arbitration. On November 3, 2025, the Plaintiff filed an arbitration action and the arbitration is expected to take place late 2026. The Company hasnot recorded a liability as of December 31, 2025, as a loss is neither probable nor estimable.

DV Energy, LLC vs Capstone Green Energy Holdings, Inc, Capstone Turbine Corporation, Capstone Green Energy Corporation, and Capstone Green Energy, LLC.

On August 26, 2024, DV Energy, LLC (“DV Energy”), a Capstone distributor in Russia, filed a lawsuit in the Superior Court of California, County of Los Angeles to recover a $0.7 million parts deposit, along with interest and legal fees. Among other things, DV Energy alleges breach of contract associated with a product order that Capstone was unable to deliver due to the imposition of U.S. sanctions following Russia’s invasion of Ukraine. The Company disputes DV Energy’s claim. DV Energy is also an unsecured creditor in the Chapter 11 proceedings of the Company’s predecessors but opted to file the complaint in the state court as well. The Bankruptcy Court placed pre-conditions on closure of the Chapter 11 proceedings. In April 2025, the Company filed motions with the Bankruptcy Court to deposit funds with the Registry of the Court pending the outcome of the state court litigation and to close the Chapter 11 proceedings. At a hearing on June 5, 2025, the Bankruptcy Court granted the Company’s motion to deposit funds with the Registry of the Court in the amount of $0.7 million as a security pending the outcome of the state court litigation. The Company has deposited the funds with the Bankruptcy Court, and the Court has issued its Final Decree and Order Closing Debtors’ Chapter 11 proceedings and Terminating Services of Kroll Restructuring Administration LLC as Claims and Noticing Agent which amount other things, closed the Chapter 11 proceedings for the Debtors with immediate effect. There isno remaining deposit liability as of December 31, 2025.

19. Segment Information

The Company has a single reportable segment: microturbine systems and their related parts, rentals and services. The Company is one line of business that provides for the development, manufacture, sale and rental of turbine generator sets and their related parts and services to customers. The Company derives revenue primarily in North America and the Company’s Chief Operating Decision Maker (“CODM”) regularly reviews financial information presented on a consolidated basis for purposes of allocating resources and assessing performance. The Company defines its CODM as the Chief Executive Officer.

The CODM assesses performance for the single reportable segment under a GAAP basis of accounting, consistent with the basis of presentation in our financial statements and decides how to allocate resources based on consolidated net loss. This measure is used to monitor performance which is compared to prior periods and forecasted results to support operational efficiencies and business expansion. The CODM does not evaluate its reportable segment using asset or liability information. There are no intra-equity sales or transfers between the reporting units within the consolidated entity.

The following table presents the Company’s information about reported segment revenue, segment gross profit, segment profit or loss and significant segment expenses that are regularly provided to the Company’s CODM as a single reporting segment and a reconciliation of the Condensed Consolidated Statement of Operations (in thousands):

20. Business Combination

On August 13, 2025, the Company entered into an Equity Purchase Agreement (the “Purchase Agreement”) to acquire 100% of the equity interests of Cal Microturbine for total consideration of approximately $14.9 million, which was comprised of $6.0 million cash paid at closing, $3.4 million in deferred consideration, and the settlement of preexisting relationships of $5.5 million. The acquisition expands the Company’s direct distribution and service capabilities in key markets and is expected to enhance operational efficiencies and customer reach. The transaction closed on August 13, 2025 (“Closing Date”) and was funded using available cash on hand.

The table below summarizes the total consideration transferred at the Closing Date (in thousands):

At the time of acquisition, Capstone and Cal Microturbine were engaged in ongoing litigation and arbitration related to their distributor agreement. As a result of the Purchase Agreement, these disputes were resolved, and mutual releases were executed. Neither company had recorded any contingent assets nor liabilities related to these matters as of the Closing Date. Refer to Note 18— Commitments and Contingencies Cal Microturbine Arbitration for further details.

The Company incurred acquisition and integration-related costs of $0.4 million and $1.3 million during the three and nine months ended December 31, 2025, which were recorded within “Selling, general and administrative” expenses on the Company’s Consolidated Statement of Operations.

The Company accounted for this acquisition using the acquisition method of accounting for business combinations in accordance with ASC 805, Business Combinations (“ASC 805”), which requires, among other things, assets acquired and liabilities assumed to be recorded at their fair value on the acquisition date. Any excess of consideration to be transferred over the estimated fair value of assets acquired and liabilities assumed is recorded as goodwill.

Determining the fair values of the assets and liabilities of Cal Microturbine requires judgment and certain assumptions to be made, the most significant of these being related to the valuation of Cal Microturbine’s customer relationships. Cal Microturbine’s customer relationship assets were valued using the multi-period excess earnings method, with significant assumptions including projected revenue, attrition rate, operating expense, selling and general administrative expenses, and discount rate. Because the valuation relies on these company-specific forecasts and assumptions rather than observable market data, the fair value measurement for customer relationships is categorized as a Level 3 measurement in the ASC 820 fair value hierarchy.

As of the date of this filing, the Company performed the preliminary analysis to assign fair value to all tangible and intangible assets acquired and liabilities assumed. As such, the preliminary purchase price allocation will be subject to further refinement and may change. The Company expects to finalize the fair value measurements as soon as practicable, but no later than 12 months from the Closing Date. No goodwill has been recognized as its management estimate as of the date of this filing is that the fair value of the net assets and liabilities acquired approximate the purchase price. However, upon finalizing its purchase price allocation, goodwill may result.

The following table summarizes the amounts of assets acquired and liabilities assumed at the acquisition date, valued at their estimated acquisition date fair value (in thousands):

Pro Forma Financial Information (Unaudited)

The following unaudited pro forma consolidated results of operations present the estimated unaudited pro forma combined results of Capstone and Cal Microturbine for the three and nine months ended December 31 2025 and 2024, as if the acquisition had occurred on April 1, 2024 and was prepared in accordance with ASC 805.

The supplemental pro forma financial information has been prepared using the acquisition method of accounting and is based on the historical financial information of Capstone and Cal Microturbine. The supplemental pro forma financial information does not necessarily represent what the combined companies’ revenue or results of operations would have been had the Cal Microturbine acquisition been completed on April 1, 2024, nor is it intended to be a projection of future operating results of the combined company. It also does not reflect any operating efficiencies or potential cost savings that might be achieved from synergies of combining Capstone and Cal Microturbine.

Cal Microturbine’s fiscal year-end is December 31, which differs from Capstone’s year-end. To ensure comparability, the pro forma financial information was prepared using comparable reporting periods. Cal Microturbine’s financial data was derived from internally generated, unaudited reports. Certain estimates were applied to allocate revenues and expenses appropriately across the periods presented in the pro forma results.

The unaudited supplemental pro forma financial information reflects pro forma adjustments related to transaction expenses incurred by Capstone and Cal Microturbine, elimination of revenue and expenses between the Capstone and Cal Micro, amortization expense due to step-up in fair value of the acquired assets, interest expense, and income tax adjustments (in thousands). The pro forma earnings below for the 2025 period were adjusted to exclude costs associated

with the acquisition that were recognized in SG&A and pro forma earnings for the 2024 period were adjusted to include these charges.
