[10-Q] Capstone Green Energy Holdings, Inc. Quarterly Earnings Report

Rhea-AI Filing Summary

Capstone Green Energy Holdings (CGEH) reported improved quarterly results. For the three months ended September 30, 2025, revenue rose to $28.4 million from $22.7 million, driven by Product and Accessories $16.1 million, Parts and Services $7.9 million, and Rentals $4.4 million. Gross profit increased to $9.0 million, and operating income reached $1.4 million, resulting in net income of $0.8 million. Year‑to‑date revenue was $56.3 million versus $38.4 million a year ago. The company completed the acquisition of Cal Microturbine on August 13, 2025, which contributed to customer concentration and accounts receivable growth.

Liquidity remains constrained with a going concern warning. Cash was $7.7 million, including $0.7 million restricted, and working capital showed a $14.2 million deficit as of September 30, 2025. Exit Notes outstanding totaled $33.2 million, including $7.0 million of Exit New Money Notes that mature on December 7, 2025; management states it does not expect internally generated cash or typical public financing methods to satisfy those obligations. Redeemable noncontrolling interests (Preferred Units) were remeasured to $32.0 million, and operating cash flow used $1.0 million in the first half. Management outlines cost reductions, pricing, and sales initiatives but notes uncertainty around refinancing the upcoming maturity.

Insights

Credit & Capital Structure Analyst

Stronger operations, but near-term debt maturity drives risk.

CGEH posted revenue of $28.4M and net income of $0.8M for the quarter, with gross profit at $9.0M. Year-to-date revenue of $56.3M reflects solid growth, aided by rentals and product sales. The acquisition of Cal Microturbine closed on Aug 13, 2025, supporting the distribution footprint.

The balance sheet shows cash of $7.7M and a working capital deficit of $14.2M. Exit Notes outstanding were $33.2M, including Exit New Money Notes of $7.0M maturing on Dec 7, 2025. Management states it does not expect internally generated cash or typical market financings (e.g., underwritten, ATM) to repay these notes, and the filing cites substantial doubt about continuing as a going concern.

Key dependencies are a successful refinancing or alternative transaction and maintaining covenant compliance. Watch liquidity covenant levels through fiscal periods ending Mar 2026 and any updates on refinancing the Exit New Money Notes ahead of Dec 7, 2025.

CAPSTONE GREEN ENERGY HOLDINGS, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

​

1. Business and Organization

Capstone Green Energy Holdings, Inc., the successor to Capstone Green Energy Corporation, along 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 on-site energy technology systems focused on helping customers around the globe solve the “Energy Trilemma” of resiliency, sustainability, and affordability. These solutions include stationary distributed power generation applications and distribution networks, including cogeneration (combined heat and power (“CHP”), integrated combined heat and power (“ICHP”), and combined cooling, heat and power (“CCHP”), renewable energy, natural resources, and critical power supply. The Company’s inverter-based technologies solve resiliency by being able to seamlessly connect to the electric grid or be the backbone of a localized microgrid. The Company’s Energy Conversion Products business line is driven by the Company’s industry-leading, highly efficient, low-emission, resilient microturbine energy systems offering scalable solutions in addition to a broad range of customer-tailored solutions. Through the EaaS business line, the Company offers build, own, operate and maintain (“BOOM”) as well as energy rental solutions utilizing the Company’s microturbine energy systems. The Company offers comprehensive service agreement plans which de-risk life-cycle costs, as well as providing aftermarket spare parts to customers not under the service agreement umbrella.

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. Post 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. On January 2, 2025, the Company’s common stock was approved for trading by Financial Industry Regulatory Authority on the over-the-counter market (“OTC”). On September 26, 2025, the trading of the Company’s common stock was approved for trading on the OTCQX Best Market.

All references in these footnotes to “the Company,” “we,” “us,” “our,” or “Capstone” are to Capstone Green Energy Holdings, Inc. and its consolidated subsidiaries.

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.

Table of Contents

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 19 – 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 six months ended September 30, 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 September 30, 2025, the Company had cash of $7.7 million, which includes restricted cash of $0.7 million, and a working capital deficit of $14.2 million. The Company had net income of $0.8 million and $0.1 million during the three and six months ended September 30, 2025, respectively.

The Exit New Money Notes will mature on December 7, 2025 (see Note 8 – Debt in the Notes to Condensed Consolidated Financial Statements for further discussion). The Company does not expect to have sufficient internally generated cash, nor does the Company expect that it could obtain sufficient financing through underwritten public offerings, at-the market offerings or other similar methods, to satisfy the obligations of the Exit New Money Notes. If the Company is unable to repay the obligations of the Exit New Money 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 New Money 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 New Money Notes.

Given the Company’s current cash position, lack of liquidity, 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 September 30, 2025. Refer to Cash Flow section 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 outcome of this uncertainty.

A robust plan to improve the Company’s future financial performance has been developed. The plan includes multiple process improvement workstreams directed 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.

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):

​

The depreciation expense was $1.9 million and $2.1 million for the six months ended September 30, 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 to twenty-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.

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 is 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 mature on December 7, 2025.

The scheduled maturities of the Company’s debt are as follows as of September 30, 2025:

​

​	​	​	​
Year Ending March 31,		​
2026 (remainder of fiscal year)	​	$	8,248
2027	​	​	25,103

Total principal payments and debt maturities	​	​	33,351
Less unamortized issuance costs	​	​	(127)
Net principal payments and debt maturities	​	$	33,224

The Exit Notes issued pursuant to the Exit Note Purchase Agreement are secured by a lien on substantially all the present and future property and assets of 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.

On March 27, 2024, the Company obtained a waiver from the Purchaser and the Collateral Agent in anticipation of default on March 31, 2024. The waiver granted was specific to the $1.0 million consolidated adjusted EBITDA covenant for the measurement date of March 31, 2024, and covered the period through June 30, 2024. There can be no assurance that the Purchase and the Collateral Agent will waive any future defaults that may occur. If future 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 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 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.

(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 at the 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):

9. Leases

Lessor

The Company rents microturbine equipment to its customers for terms ranging from a couple of months to up to ninety-six months with most of the leases generally with thirty-six month terms with an extension 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 September 30, 2025, the Company’s minimum rental revenue to be received was as follows (in thousands):

 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 and renewal options for five-year periods. Lease expense is recognized on a straight-line basis over the term of the lease, which may include extension periods.

During the six months ended September 30, 2025, the Company did not 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 modified four of their current lease agreements during the six months ended September 30, 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 September 30, 2025, lease commitments totaled approximately 19.0 megawatts of microturbines and had an average term of 34 months and a total remaining commitment value of approximately $7.7 million.

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:

● Identification of the contract, or contracts, with a customer

● Identification of the performance obligations in the contract

● Determination of the transaction price

● Allocation of the transaction price to the performance obligations in the contract

● Recognition of revenue when, or as, the Company satisfies a performance obligation

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, upon the transfer of control in accordance with the contractual terms and conditions of the sale. The revenue associated with accessories is recognized at a point in time when the accessory 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 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 and Service Cost Reimbursement In addition to the provision of standard warranties, the Company offers Factory Protection Plans (“FPP”) 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 FPP contract, in 30-day intervals aligned to the monthly service period for that customer. FPP contracts have an initial term period of one year, with maximum durations of 5, 10, 15, or 20 years and may be cancelled at any time. The related costs for FPP 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. The provision is periodically adjusted to reflect actual experience. FPP contracts typically go into effect once the standard warranty expires.

Comprehensive FPP 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 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.

Some FPPs offer 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.

16

Table of Contents

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, FPP parts 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 service contracts are distinct, the Company considers the following factors for each FPP and 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 FPP and services 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):

​

​	​	​	​	​	​	​
​		Six Months Ended September 30,
​	​	2025		​	2024
​	​	​	​	​	​	​
Opening balance, beginning of the fiscal year	​	$	13,949	​	$	11,858
Closing balance, end of the period	​	$	12,883	​	$	9,884
Revenue recognized in the period from:	​		​	​	​	​
Amounts included in deferred revenue at the beginning of the period	​	$	9,375	​	$	5,656

Deferred revenue attributed to FPP 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 September 30, 2025, approximately $4.0 million of revenue is expected to be recognized from the remaining contract liability for FPP contracts. The Company expects to recognize revenue on approximately $3.6 million of these unfulfilled performance obligations over the next 12 months and the balance of $0.4 million will be recognized thereafter.

The Distributor Support System (“DSS”) provides additional support for distributor business development activities, customer lead generation, brand awareness and tailored marketing services for each of the Company’s major geographic and market verticals. This program is funded by the distributors and was developed to provide improved worldwide distributor training, sales efficiency, website development, company branding and funding for increased strategic marketing activities. DSS program revenue is generally paid quarterly with revenue recognized on a straight-line basis over the corresponding service period. Capstone Distributor Support Services Corporation (“CDSSC”), a related party, owns and operates the DSS program for the Company under a service agreement. Refer to Note 17— Commitments and Contingencies— Services Agreement between Reorganized PrivateCo and Operating Subsidiary for further details.

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 than one 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.

18

Table of Contents

Practical Expedients

The Company applies the practical expedient for contracts of one 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 to twenty-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 September 30, 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 480-10-S99-3A 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”). 

19

Table of Contents

Subsequent measurement under ASC 480-10-S99-3A for the redemption value follows the definition of redemption value as per the Capstone Green Energy LLC Agreement, which has been defined as 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 six months ended September 30, 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 $2.75 and $0.75 as of September 30, 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. 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 September 30, 2025, the Preferred Units have been adjusted to their maximum redemption value of $32.0 million.

12. 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 six months ended September 30, 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 stock holders.

The Company did not have any outstanding stock options or warrants as of September 30, 2025. As of September 30, 2025, the Company adjusted the carrying value of the Preferred Units as discussed in Note 11— Temporary Equity above.

14. 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:

● Quoted prices for similar assets or liabilities in active markets

● Quoted prices for identical or similar assets or liabilities in inactive markets

● Inputs other than quoted prices that are observable for the asset or liability

● Inputs that are derived principally from or corroborated by observable market data by correlation or other means

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.

21

Table of Contents

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.

​

15. 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 were no 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 September 30, 2025 and 2024.  The Company recorded expense of approximately $0.2 million for the six months ended September 30, 2024.

16. Balance Sheet Information

Prepaid Expenses and Other Assets

As of September 30, 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 did not exist as of September 30, 2025, or March 31, 2025.

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

Other Commitments

The Company has agreements with certain of its distributors requiring that, if the Company renders parts obsolete in inventories the distributors own and hold in support of their obligations to serve fielded microturbines, then the Company is required to replace the affected stock at no cost to the distributors. 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 September 30, 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 a final settlement hearing date has been set for November 13, 2025. 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. The Company has not recorded a liability as of September 30, 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 is no remaining deposit liability as of September 30, 2025.

18. 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):

19. 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):

​

​	​	​	​
​	​	As of the Closing Date
Cash paid at close	​	$	5,951
Deferred consideration (1)	​	​	3,427
Settlement of preexisting relationships (2)	​	​	5,538
Total consideration	​	$	14,916

​

(1) The deferred consideration reflects cash payments of $4.0 million which will be distributed over 24 monthly installments starting in January 2026. These payments were discounted to their present value using an 11.45% discount rate.

(2) The settlement of preexisting balances related to accounts receivable and deferred revenue.

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 17— Commitments and Contingencies Cal Microturbine Arbitration for further details.

​

The Company incurred acquisition and integration-related costs of $0.9 million during the three months ended September 30, 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.

26

Table of Contents

​

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 approximates 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):

​

​	​	​	​
​	​	Acquisition Date Fair Value
Assets acquired	​	​	​
Cash	​	$	7,361
Accounts receivable	​	​	6,689
Inventories	​	​	760

Net assets acquired	​	$	14,916

​

(1) The intangible asset relates to customer relationships and was determined to have a weighted average amortization period of 6 years.

The post-closing operating results of Cal Microturbine have been included in our consolidated financial statements. For the period from the Closing Date through September 30, 2025, the Company’s Consolidated Statements of Operations includes Cal Microturbine revenue of $708 thousand and earnings of $221 thousand.

​

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 months ended September 30, 2025 and 2024, and the six months ended September 30, 2025 and 2024, as if the acquisition had occurred on April 1, 2024 and was prepared in accordance with ASC 805.

​

Table of Contents

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 was adjusted to include these charges.

Overview

Capstone Green Energy Holdings, Inc., the successor to Capstone Green Energy Corporation along 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 on-site energy technology systems focused on helping customers around the globe solve the “Energy Trilemma” of resiliency, sustainability, and affordability. These solutions include stationary distributed power generation applications and distribution networks, including cogeneration (combined heat and power (“CHP”), integrated combined heat and power (“ICHP”), and combined cooling, heat and power (“CCHP”), renewable energy, natural resources, and critical power supply.

We are a market leader in microturbine energy systems based on the number of microturbines sold annually and total installed base. Generally, power purchased from the electric utility grid is less costly than power produced by distributed generation technologies in simple cycle mode. Utilities may also charge fees to interconnect with their power grids. However, when considering and including the waste heat from our microturbine (CHP and CCHP) the economic benefit improves significantly. Further, our highly efficient, low emission, resilient technology can produce thermal energy at a lower carbon footprint. These benefits can be enhanced when fuel costs are low, where the costs of connecting to the grid may be high or impractical (such as remote power applications or new grid services need to be provided), where reliability and power quality are of critical importance, or in situations where peak shaving could be economically advantageous because of highly variable electricity prices. Our microturbines are an inverter-based technology and can be interconnected to other distributed energy resources to form “microgrids” (also called “distribution networks”) located within a specific geographic area and provide power to a group of buildings. Because our microturbines can provide a reliable source of power and can operate on multiple fuel sources, management believes they help solve the “Energy Trilemma” of resiliency, sustainability and affordability. Management also believes our products and services offer a level of flexibility not currently offered by other technologies such as reciprocating engines. We are currently exploring energy conversion options for the smaller end of the power spectrum.

During the three months ended September 30, 2025, we had a net income of $0.8 million, accretion of dividends of Preferred Units of $18.2 million, basic and diluted net loss per share of $0.89, compared to net loss of $0.4 million, no change in Preferred Units and basic and diluted net loss per share of $0.02 during the three months ended September 30, 2024. The $1.3 million change in net income was primarily due to improved gross profit of $2.0 million, driven by the impacts of price increases and lower unit costs, offset by $0.6 million higher total operating expenses, a $0.1 million decrease in other income and a $0.1 million increase in interest expense as compared to the three months ended September 30, 2024.

In the energy markets, we continue to expand our presence in the energy efficiency, natural resources, renewable energy, critical power, and microgrid power type of applications in the first half of Fiscal 2026. The microgrid market is for electrification demand. The renewable energy market is fueled by landfill gas, biodiesel and biogas from sources such as food processing, agricultural waste and livestock manure. Our product sales in the oil and gas and other natural resources market is driven by our microturbines’ reliability, emissions profile and ease of installation. Given the continued volatility of the oil and gas market, our business strategy is to continue diversification within the microgrid energy efficiency and renewable energy markets.

As part of our diversification strategy, we have begun to utilize our microgrid solutions into a reference design package for AI and Data Center infrastructure. On October 21, 2025, we released a press release announcing that the Company has developed a new 800-volt direct-current (“VDC”) microturbine to support NVIDIA’s new AI Infrastructure requirements.  With the Company’s compute partner, Microgrid for AI (“MG4AI), the Company can now provide power and cooling plus compute as an engineered equipment package as “on-site power to chip” for the next generation of AI factories. Refer to Risk Factors (Part II, Item 1A of this Form 10-Q) for further discussion of the risks associated with AI-related investments.

We continue to focus on improving our products based on customer input, building brand awareness and bringing new channels to market by developing a diversified network of strategic distribution partners. Our focus is on products and solutions that provide near-term and longer-term opportunities to drive repeatable business and larger deal size rather than discrete projects for niche markets. In addition, management closely monitors operating expenses and strives to improve manufacturing efficiencies while simultaneously lowering direct material costs and increasing average selling prices. The key drivers to our success are higher average selling prices, lower direct material costs, positive new order flow, reduced cash usage and expansion of the EaaS business.

Backlog Net product orders were approximately $6.2 million and $9.2 million for the three months ended September 30, 2025 and 2024, respectively. Ending backlog was approximately $14.8 million at September 30, 2025, compared to $10.6 million at September 30, 2024. The book-to-bill ratio was 0.4:1 and 0.8:1 for the three months ended September 30, 2025 and 2024, respectively. Book-to-bill ratio is the ratio of new orders we received to units shipped and billed during a period.

The timing of the backlog is based on the requirement date indicated by our customers and part availability. However, based on historical experience, management expects that a portion of our backlog may not be shipped within the next 12 months. Additionally, the timing of shipments is subject to change based on several variables (including customer deposits, payments, availability of credit and customer delivery schedule changes), most of which are not within our control and can affect the timing of our revenue. As a result, management believes the book-to-bill ratio reflects the current demand for our products in the given period.

We believe that effective execution in each of these key areas will be necessary to leverage our promising technology and early market leadership into achieving positive cash flow with growing market presence and improving financial performance.

We currently occupy warehouse and office space in Costa Mesa, California and office space and a production facility in Van Nuys, California with a production capacity of approximately 2,000 units per year, depending on product mix.

Critical Accounting Estimates

Our discussion and analysis of our financial condition and results of operations is based upon our Condensed Consolidated Financial Statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The preparation of these Condensed Consolidated Financial Statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, and expenses and related disclosures of contingent liabilities. On an ongoing basis, we evaluate our estimates, including but not limited to those related to credit losses, inventories, warranty obligations, redeemable noncontrolling interest valuation and stock-based compensation. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. The results of these estimates and assumptions which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

We consider an accounting estimate to be critical if: (1) the accounting estimate requires us to make assumptions about matters that were highly uncertain at the time the accounting estimate was made, and (2) changes in the estimate that are reasonably likely to occur from period to period, or use of different estimates that we reasonably could have used in the current period, would have a material impact on our financial condition or results of operations.

Item 7 of our Annual Report on Form 10-K for the fiscal year ended March 31, 2025 describes the significant accounting estimates used in the preparation of our Condensed Consolidated Financial Statements.

For the three months ended September 30, 2025, revenue from microturbine products and accessories increased $4.8 million, or 42%, to $16.1 million from $11.3 million for the three months ended September 30, 2024. The $4.8 million increase was driven primarily by an increase in product demand, with the 4.3 megawatts increase in shipments during the three months ended September 30, 2025, including increased demand for our C1000 turbines, compared to the three months ended September 30, 2024. Average revenue per megawatt shipped was approximately $1.4 million and $1.6 million during the three months ended September 30, 2025 and 2024, respectively. The decrease in revenue per megawatt is mainly due to product mix of microturbine configurations.

Parts and service revenue, which are part of our EaaS business line and includes revenue from our spare parts shipments, FPP contracts, and other service revenue of $7.9 million for the three months ended September 30, 2025, was comparable at $7.9 million for the three months ended September 30, 2024.

Rentals revenue for three months ended September 30, 2025 increased $0.9 million or 26%, to $4.4 million from $3.5 million for the three months ended September 30, 2024. This increase was driven by an increase in rental utilization and increased rental prices.

Sales to E-Finity Distributed Generation (“E-Finity”), Cal Microturbine, LLC (“Cal Microturbine”) and Lone Star Power Solutions, LLC (“Lone Star”), three of the Company’s domestic distributors, accounted for 36%, 13% and 10% of revenue for the three months ended September 30, 2025, respectively. On August 13, 2025, the Company completed its acquisition of Cal Microturbine.  E-Finity, Arctic Energy Inc. (“Arctic”) and Lone Star Power Solutions, LLC (“Lone Star”), three of the Company’s domestic distributors, and GET/CWS Limited, one of the Company’s international customers, accounted for 21%, 14%, 10% and 11% of revenue for the three months ended September 30, 2024, respectively.

an increase in cash of $0.6 million during the six months ended September 30, 2024. The decrease in cash during the six months ended September 30, 2025 was primarily due to net cash used in operating activities.

Operating Activities During the six months ended September 30, 2025, net cash used by operating activities was $1.0 million, consisting of a net income for the period of $0.1 million, changes in operating assets and liabilities of $7.0 million offset by non-cash adjustments, primarily representing depreciation and amortization, non-cash lease expense, stock based compensation, paid-in-kind interest expense, provision for credit losses and inventory write-down totaling $5.9 million.

For the six months ended September 30, 2024, net cash provided by operating activities was $0.9 million, consisting of net loss of $4.4 million, offset by changes in operating assets and liabilities of $1.5 million and non-cash adjustments, primarily representing depreciation and amortization, non-cash lease expense and paid-in-kind interest expense, totaling $6.7 million.

The following is a summary of the significant sources (uses) of cash from operating activities (in millions):

The $6.4 million increase in use of cash in accounts receivable resulted from the timing of sales in the six months ended September 30, 2025 compared to the six months ended September 30, 2024. The $2.8 million decrease in cash provided by inventory is due to higher shipment at quarter-end. The $1.7 million increase in cash provided by accounts payable resulted from the timing of payment of trade accounts. The $0.5 million increase in cash provided by accrued expenses was primarily due to an increase in the AIP bonus accrual compared to no bonus accrual in the six months ended September 30, 2024. The $0.4 million decrease in use of cash by operating lease liability was primarily due to a decrease in lease liability. The $1.5 million decrease in cash provided from prepaid and other assets is primarily the result of usage of prepaid inventory. The $2.5 million increase in cash provided by FFP liability was primary driven by an increase in value of new claims outpacing the fulfillment of claims. The $0.3 million increase in cash used in other operating assets and liabilities, was primarily driven by an increase in cash used in deferred revenue of $0.2 million primarily driven by increased shipments in the six months ended September 30, 2025 compared to the six months ended September 30, 2024, lowering related customer deposits.

Investing Activities Net cash provided in investing activities was $1.0 million during the six months ended September 30, 2025 and was primarily due to cash acquired in acquisitions net of cash paid. Net cash used in investing activities was $0.2 million during the six months ended September 30, 2024, and was primarily due to investments in operating and rental fleet assets.

Financing Activities Net cash used in financing activities of $1.0 million and $0.1 million during the six months ended September 30, 2025 and 2024, respectively, was primarily used for repayment of finance lease obligations. Additionally, during the six months ended September 30, 2025, treasury stock was accumulated as a result of the tax withholdings of employee stock vesting.

Going Concern In connection with the preparation of the Condensed Consolidated Financial Statements for the six months ended September 30, 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 September 30, 2025, the Company had cash of $7.7 million, which includes restricted cash of $0.7 million, and a working capital deficit of $14.2 million. The Company had net income of $0.8 million and $0.1 million during the three and six months ended September 30, 2025, respectively.

A robust plan to improve the Company’s future financial performance has been developed. The plan includes multiple process improvement workstreams directed 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, 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 to result in our ability to meet our payment obligations coming due within the twelve month period after the date of this report.

The Company and its advisors are considering various alternatives to address the upcoming maturity of the Exit New Money 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 New Money Notes.

​

Given the Company’s current cash position, lack of liquidity, 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 September 30, 2025.

New Accounting Pronouncements Refer to Note 3— Recently Issued Accounting Pronouncements in the Notes to Condensed Consolidated Financial Statements (Part I, Item 1 of this Form 10-Q) for information regarding new accounting standards.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

As a “smaller reporting company,” as defined by Item 10 of Regulation S-K, we are not required to provide information required by this Item.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure the information required to be disclosed in our reports under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives.

In connection with the preparation of this Form 10-Q for the three and six months ended September 30, 2025, an evaluation was performed under the supervision and with the participation of our management, including our CEO and CFO, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in and pursuant to Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on this evaluation, our CEO and CFO have concluded that, as of September 30, 2025, due to the material weaknesses in our internal control over financial reporting described below, our financial reporting controls and procedures were not effective.

Notwithstanding the identified material weakness, management believes the consolidated financial statements included in this Form 10-Q fairly present, in all material respects, our consolidated financial position and consolidated

results from operations and cash flows for the quarter ended September 30, 2025, and our financial condition as of each such date and have been prepared in conformity with GAAP.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over our financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act as a process designed by, or under the supervision of, our CEO and CFO and effected by our Board, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP and includes those policies and procedures that:

● Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets;

● Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and

● Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

​

We conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on this evaluation, management concluded that our internal control over financial reporting was not effective as of March 31, 2025 because of the material weakness described below.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of a company’s annual and interim financial statements will not be detected or prevented on a timely basis. The following material weakness was identified:

● We did not design and maintain effective controls over financial reporting related to the proper accounting, presentation and disclosure for FPP service contracts, including controls relating to the relevant information technology systems used in this process.

Management’s Remediation Plan

Management, with the direction and oversight of the Audit Committee and the Board of Directors, is engaged in remediation actions to address the material weakness described above. The Company’s remediation actions include, but are not limited to the following:

● Management has reviewed and refined the Company’s current accounting memorandums related to FPP service contracts to address the proper financial reporting considerations. Additionally, management is enhancing the design of and implementing controls over financial reporting for FPP service contracts, including controls over the Information Technology systems specifically used in Company’s process for receiving notice of FPP claims.

We believe these measures will remediate the material weakness, but management is assessing the need for any additional steps to remediate the underlying causes that gave rise to this weakness. The material weakness will not be considered remediated until the applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively. There is no assurance that additional remediation steps will not be necessary.

There were no changes in our internal control over financial reporting during the most recent fiscal quarter that were identified in connection with management’s evaluation required by paragraph (d) of Rules 13d-15 and 15d-15 under the Exchange Act that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent limitations of the Effectiveness of Internal Control

A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the internal control system are met. Because of the inherent limitations of any internal control system, no evaluation of controls can provide absolute assurance that all control issues, if any, within a company have been detected.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

Refer to Note 17 – Commitments and Contingencies — Legal Matters, in the Notes to Condensed Consolidated Financial Statements (Part I, Item 1 of this Form 10-Q) for information regarding legal proceedings in which we are involved. The Company is from time to time a party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of business. In addition, the Company and certain of its former and current directors and officers are party to several material legal proceedings. The outcome of litigation is inherently uncertain. If one or more legal matters were to be resolved against the Company in a reporting period for amounts in excess of management’s expectations, the Company’s financial condition and operating results for that reporting period could be materially adversely affected.

Item 1A. Risk Factors

In addition to the other information set forth in this report, you should carefully consider the factors discussed in the “Risk Factors” section contained in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2025, together with the cautionary statement under the caption “Special Note Regarding Forward-Looking Statements” included elsewhere in this Quarterly Report on Form 10-Q. The risks described are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

There is substantial doubt about the Company's ability to continue as a going concern, and this may adversely affect the Company's stock price and the Company's ability to raise capital.

In connection with the preparation of these Condensed Consolidated Financial Statements for the three and six months ended September 30, 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 September 30, 2025, the Company had cash of $7.7 million and a working capital deficit of $14.2 million. The Company had net income of $0.8 million and $0.1 million during the three and six months ended September 30, 2025, respectively.

The Exit New Money Notes (as defined in Note 8 – Debt) will mature on December 7, 2025 (see Note 8 – Debt in the Notes to Condensed Consolidated Financial Statements for further discussion). The Company does not expect to have sufficient internally generated cash, nor does the Company expect that it could obtain sufficient financing through underwritten public offerings, at-the market offerings or other similar methods, to satisfy the obligations of the Exit New Money Notes. If the Company is unable to repay the obligations of the Exit New Money 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 New Money 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 New Money Notes.

Given the Company’s current cash position, lack of liquidity, short term debt maturity, 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 September 30, 2025. The substantial doubt about the Company's ability to continue as a going concern may affect the price of the Company's common stock and the grade of its credit rating, may negatively impact relationships with third parties with whom the Company does business, including customers, vendors and lenders, may impact the Company's ability to raise additional capital or implement its business plan.

The Exit Note Purchase Agreement, as amended, defines an event of default as, among other things, payment default, bankruptcy events, cross defaults, breaches of covenants and representations and warranties, changes of control,  and judgment defaults. An event of default, if not waived, could have a material adverse effect on the Company. In the event the Company fails to meet its obligations to repay the Exit New Money Notes, the collateral agent under the Exit Note Purchase Agreement, may enforce any and all liens and security interests on the collateral the Company has used to secure the Notes and the Company may forfeit its right to such collateral.

There are uncertainties and risks related to the profitability, safety and regulatory environment of AI that could adversely affect our business and operations.

In order to position ourselves to take advantage of growth opportunities, we have made, and may continue to make, investments, strategic acquisitions, mergers, partnership, joint ventures and alliances related to AI-infrastructure and data centers that involve significant risks and uncertainties. The Company has only recently begun to pursue initiatives in AI related technologies and has not made any sales to AI infrastructure clients. Some of the Company’s competitors, including competitors that have significantly greater resources, have already successfully generated revenues from AI business lines. AI technologies and their uses are currently evolving rapidly. If the Company fails to successfully integrate its products in AI infrastructure or develop new products in response to changes in technology or industry standards, or the Company fails to bring product enhancements or new product developments to market quickly enough, the Company’s products could rapidly become less competitive or obsolete for use in the development of AI infrastructure. Thus, the future profitability of any AI-related investments is highly uncertain and such investments may adversely affect our business and operations.

The regulatory landscape surrounding AI is also evolving rapidly, and we anticipate increased scrutiny and potential regulation in the near and long term. If we continue to invest in utilizing our products for the development of AI data centers and other AI infrastructure, then any such developments may significantly impact our business and operations in ways that are difficult to predict. Governments and regulatory bodies are considering measures to ensure the responsible development and deployment of AI systems, including transparency, accountability, and fairness guidelines. The amount of energy used for AI has also received significant attention, and it is expected that energy efficiency and sustainability will be critical factors regulating AI data centers.
