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.

Going Concern In connection with the preparation of these Condensed Consolidated Financial Statements for the three months ended June 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 June 30, 2025, the Company had cash of $6.6 million and a working capital deficit of $14.2 million. The Company incurred a net loss of $0.7 million during the three months ended June 30, 2025.

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 June 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 with the needed 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 result in our ability to meet our payment obligations coming due within the twelve-month period after the date of this report.

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

The Company determines revenue recognition through the following steps:

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

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

Accessories and Parts The Company recognizes revenue when performance obligations identified under the terms of contracts with its customers are satisfied, which generally occurs, for accessories, 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 automatic renewals with 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 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 more aligned to our current presentation of product sales, generally. After the commencement date, the Company recognizes the imputed interest income as part of the net sales using the effective interest method.

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

Contracts with Multiple Performance Obligations

The Company enters into contracts with its customers that often include promises to transfer multiple products, parts, accessories, 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 relative standalone selling price (“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.

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.

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.

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.
