Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors of

Capstone Energy +, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Capstone Energy+, Inc. (the “Company”) as of March 31, 2026 and 2025, the related consolidated statements of operations, temporary equity and stockholders’ deficit, and cash flows for each of the two years in the period ended March 31, 2026 and 2025, and the related notes** **(collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of March 31, 2026 and 2025, and the results of its operations and its cash flows for each of the two years in the period ended March 31, 2026, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits** **provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Net Realizable Value of Inventories

Description of the Matter

The Company’s inventories totaled approximately $24.8 million as of March 31, 2026 and approximately $2.7 million of inventories were classified as long-term on the Company’s consolidated balance sheet. As described in Note 2 to the consolidated financial statements, management values inventories at the lower of cost (determined on a first-in-first-out basis) or net realizable value. In determining this estimate, the Company will both (a) perform a monthly analysis to compare the previous 36-month usage of its inventories to the current quantities on hand and (b) judgmentally review their

inventories for any non-recurring adjustments that may be necessary based on their knowledge of the business. Changes in the assumptions used could have a significant impact on the net realizable value of inventories.

The principal considerations for our determination that performing procedures relating to the net realizable value of inventories is a critical audit matter are (i) the significant judgement required by management when determining the net realizable value; and (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures to evaluate management’s estimate and significant assumptions in determining the net realizable value.

How We Addressed the Matter

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included, among others:

◾Obtained an understanding of the Company’s financial reporting processes in place to estimate the net realizable value of inventories;
◾Compared the assumptions made by management in evaluating its slow moving or obsolete goods to prior years to ensure such estimates and policies have remained consistent;
◾Tested management’s calculation and significant assumptions made in determining its current year net realizable value of inventories, which included substantively testing the inventory usage and movement used in such calculations;
◾Performed an independent sensitivity analysis to determine whether or not material differences in the net realizable value of inventories existed if management were to use a different look-back time period in their calculation; and
◾Performed a retrospective analysis of the Company’s net realizable value of inventories by comparing the Company’s historical write-downs in prior periods to the actual current period usage and movement.

Valuation of Intangible Assets Acquired in a Business Combination

Description of the Matter

As described in Note 20 to the consolidated financial statements, the Company completed the acquisition of Cal Microturbine on August 13, 2025. The Company accounted for this transaction under the acquisition method for business combinations in accordance with ASC 805. Accordingly, the purchase price was allocated to the assets acquired and liabilities assumed based on their respective fair values, including identified customer relationship related intangible assets.

We identified the valuation of the customer relationship related intangible asset as a critical audit matter due to (i) the significant estimates and assumptions made by management, (ii) high degree of auditor judgment when performing audit procedures to evaluate the reasonableness of management's forecast of future cash flows, and (iii) use of significant unobservable inputs and assumptions, including the need to involve our fair value specialists.

How We Addressed the Matter

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included, among others:

◾Obtained an understanding of management's process over the valuation of customer relationship related intangible asset;
◾Evaluated the reasonableness of forecasted future cash flows used in valuation of the customer relationship related intangible asset by comparing to contracts, historical results, and other metrics;
◾With the assistance of our fair value specialists, evaluated the reasonableness of the valuation methodology, and significant unobservable inputs and assumptions by:
otesting the source information underlying the determination of certain significant unobservable inputs and assumptions,
odeveloping a range of independent estimates for other unobservable assumptions and comparing them to the assumptions used by management, and
otesting the mathematical accuracy of the calculations.
