Delivering on Our Pillars: Q4 Results Show the Power of Focused Execution

Earnings Results Conference Call Webcast to be Held on July 2, 2025

Capstone Green Energy Holdings, Inc. (the "Company” or “Capstone”) (PINK: CGEH), the public successor to Capstone Green Energy Corporation, announced its financial results for the fourth quarter and full fiscal year ended March 31, 2025. The Company continues to focus on driving its Three Pillar strategy: (1) financial health, (2) sustainable excellence, and (3) revitalizing culture and talent. These Three Pillars are intended to drive behavioral changes in our culture, generating results that lead to strong and sustainable financial performance.

Revenue for the fourth quarter and year-to-date fiscal year 2025 were $27.1 million and $85.6 million, compared to the fourth quarter and year-to-date revenues in the fiscal year 2024 of $24.3 million and $91.2 million, respectively. The fourth-quarter revenue improved by $2.8 million year-over-year, driven by increased demand for products and services, as well as improved rental utilization rates within the company's Energy as a Service (EaaS) revenue stream. Slow product sales in the first half of the fiscal year caused a decrease of $5.7 million for the year. This was mainly due to restructuring hesitancy and instability in Europe.

Fourth Quarter Fiscal 2025 Highlights:

• Gross profit for the fourth quarter of 2025 was $7.5 million, which was $4.9 million higher than the fourth quarter of fiscal 2024. Further, gross margin was 28%, which was a 17% improvement over the fourth quarter of fiscal 2024. The $4.9 million gross profit increase was driven by higher product and rental pricing, higher rental fleet utilization, cost efficiencies, and improving productivity from operations. Gross margin improvement was primarily driven by product price increases implemented during fiscal 2025, along with stronger financial and business discipline across the rentals, service agreements, and parts categories.
• The Company delivered a net loss of $0.1 million for the fourth quarter of fiscal 2025 compared to a net loss of $5.3 million for the fourth quarter of fiscal 2024.
• Adjusted EBITDA for the fourth quarter of fiscal 2025 was $2.8 million versus negative $0.8 million for the fourth quarter of fiscal 2024, improving $3.6 million primarily due to improved gross margin and lower operating expenses reflecting the financial and business discipline actions taken during the year.
• Total cash as of March 31, 2025, was $8.7 million, an increase of $6.6 million from March 31, 2024.

Year-to-Date Fiscal 2025 Highlights:

• Gross Profit for fiscal year 2025 was $23.3 million with a margin of 27% compared to gross profit of $14.3 million and a margin of 16% for fiscal year 2024. The increase of $9.0 million over fiscal 2024 resulted from a shift in sales mix and the effect of price increases implemented during fiscal year 2025. Product and accessories sales, as a percentage of total revenue, declined to 47% in fiscal 2025 from 54% in fiscal 2024. As stated earlier, this was mainly due to the lingering effects of restructuring activities completed in fiscal 2024 and weaker European sales.
• Net loss was $7.2 million for fiscal year 2025, compared to a net income of $7.4 million for fiscal year 2024, which included net reorganization gain of $32.5 million. Excluding the reorganization gain, the net loss improved by $17.9 million, driven by improved gross profit, lower total operating expenses, lower restatement and restructuring costs, and lower interest costs.
• Adjusted EBITDA for fiscal year 2025 improved significantly to $7.9 million from negative $0.5 million for fiscal year 2024. Adjusted EBITDA included significant addbacks for restructuring, shareholder litigation, restatement costs, and SEC investigation costs. These non-recurring matters have come to conclusion in the first quarter of fiscal 2026.
• Net cash provided by operating activities was $7.7 million for the twelve months ended March 31, 2025. This positive change was mainly a result of the reduced net loss and improved working capital.
• The Company continues to remain compliant with its financial covenants.

“The Company has taken great strides over the past year. We are pleased with the Company's fourth-quarter results for fiscal 2025, which reflect the improvements in our services and rental business revenues, and lower costs of goods sold driven by our cost-out initiatives. Additionally, the impact of the fiscal 2025 strategic price increases across the portfolio improved margins. The Company’s full year results reflect the focus on financial health with $9.0 million increase in gross profit and $7.9 million of positive Adjusted EBITDA in fiscal 2025. The continued execution of our corporate initiatives focused on financial and commercial discipline were essential to the improved financial performance and the discipline has become embedded in our culture,” said John Juric, Chief Financial Officer of Capstone. “Now as we move into fiscal year 2026, we are working to elevate the positioning of the Company’s stock to the OTC:QX market, while continuing to focus on our longer-term goal of relisting on Nasdaq or a similar national exchange.”

Mr. Juric further commented, “The previously disclosed SEC investigation has been closed with no action taken by the SEC. The Company is pleased with the outcome of the investigation and can now focus on the strategic growth of the business.”

“What we have accomplished in fiscal Year 2025 was historic for Capstone. In all of its 37-year history, the Company has never delivered a positive Adjusted EBITDA over a full fiscal year. We have changed the culture and truly changed the landscape of what Capstone’s true potential is,” said Vince Canino, President & Chief Executive Officer of Capstone. “Our steady improvements in financial health, operational excellence, and the revitalization of our culture and talent have strengthened our focus on core values. With strong market tailwinds and a demonstrated path to profitability, we believe we are well-positioned to take the business to new heights.”

Cautionary Notes

This release contains forward-looking statements as defined in the Private Securities Litigation Reform Act of 1995, including statements related to future profitability and the growth of the business. The Company has tried to identify these forward-looking statements by using words such as “expect,” “anticipate,” “believe,” “could,” “should,” “estimate,” “intend,” “may,” “will,” “plan,” “goal” and similar terms and phrases, but such words, terms and phrases are not the exclusive means of identifying such statements. Actual results, performance and achievements could differ materially from those expressed in, or implied by, these forward-looking statements due to a variety of risks, uncertainties and other factors, including, but not limited to, the following: the Company’s liquidity position and ability to access capital; the Company’s ability to continue as a going concern; the Company’s ability to successfully remediate the material weakness in internal control over financial reporting; the Company’s ability to realize the anticipated benefits of its financial restructuring; the Company’s ability to comply with the restrictions imposed by covenants contained in the exit financing and the new subsidiary limited liability company agreement; the uncertainty associated with the imposition of tariffs and trade barriers and changes in trade policies; employee attrition and the Company’s ability to retain senior management and other key personnel following the restructuring; the Company's ability to develop new products and enhance existing products; product quality issues, including the adequacy of reserves therefor and warranty cost exposure; intense competition; financial performance of the oil and natural gas industry and other general business, industry and economic conditions; including the impacts of any changes in tariff policies; the impact of litigation and regulatory proceedings; the potential material adverse effect on the price of the Company’s common stock and stockholder lawsuits. For a detailed discussion of factors that could affect the Company’s future operating results, please see the Company’s filings with the Securities and Exchange Commission, including the risk factors contained in our most recent Annual Report on Form 10-K. Except as expressly required by the federal securities laws, the Company undertakes no obligation to update or revise any forward-looking statements, whether as a result of new information, changed circumstances or future events or for any other reason.

To supplement the Company’s unaudited financial data presented on a generally accepted accounting principles (GAAP) basis, management has presented Adjusted EBITDA, a non-GAAP financial measure. This non-GAAP financial measure is among the indicators management uses as a basis for evaluating the Company’s financial performance as well as for forecasting future periods. Management establishes performance targets, annual budgets and makes operating decisions based in part upon this metric. Accordingly, disclosure of this non-GAAP financial measure provides investors with the same information that management uses to understand the company’s economic performance year-over-year.

EBITDA is defined as net income (loss) before interest, provision for income taxes and depreciation and amortization expense. Adjusted EBITDA is defined as EBITDA before stock-based compensation, restructuring, financing, shareholder litigation, non-recurring legal, restatement and SEC investigation expenses, and reorganization items. Restructuring expenses relate to the Chapter 11 bankruptcy filing and financing expenses related to the evaluation and negotiation of the Company’s senior indebtedness. Shareholder litigation expense resulted from the restatement of the Company’s financials and non-recurring legal expenses are one-time non-recurring legal fees. Restatement expenses are professional fees related to the restatement of the Company’s prior year financials. SEC investigation expenses relate to the costs arising from the restatement of the Company’s financials. Reorganization items represent adjustments occurring during the bankruptcy period.

Adjusted EBITDA is not a measure of the Company’s liquidity or financial performance under GAAP and should not be considered as an alternative to net income or any other performance measure derived in accordance with GAAP, or as an alternative to cash flows from operating activities as a measure of its liquidity.

While management believes that the Company’s presentation of Adjusted EBITDA provides useful supplemental information to investors, there are limitations associated with the use of this non-GAAP financial measure. Adjusted EBITDA is not prepared in accordance with GAAP and may not be directly comparable to similarly titled measures of other companies due to potential differences in the methods of calculation. The Company’s non-GAAP financial measure is not meant to be considered in isolation or as a substitute for comparable GAAP financial measures and should be read only in conjunction with the Company’s consolidated financial statements prepared in accordance with GAAP.
