Capstone Green Energy Delivers Continued Profitability and Margin Expansion in Second Quarter Fiscal 2026

Operational Efficiency and Product Mix Drive $2.0 Million Increase in Gross Profit

Six Straight Quarters of Positive Adjusted EBITDA Highlight Continued Discipline

LOS ANGELES--(BUSINESS WIRE)-- Capstone Green Energy Holdings, Inc. (the “Company” or “Capstone”), and its subsidiaries (OTCQX: CGEH), announced its financial results for the second quarter of fiscal year 2026, ended September 30, 2025. The Company’s ongoing transformation and disciplined execution are driving measurable results, underscored by improving financial health, growing customer confidence, and expanding participation in key growth markets.

The Company completed its acquisition of Cal Microturbine, LLC (“Cal Microturbine”) on August 13, 2025. This acquisition expands the Company’s direct distribution and service capabilities in key markets and is expected to enhance operational efficiency and customer reach. Post acquisition, the Cal Microturbine acquisition contributed an additional $0.7 million in revenue and $0.2 million in earnings.

Revenue for the second quarter and year-to-date fiscal year 2026 was $28.4 million and $56.3 million, respectively, compared to $22.7 million and $38.4 million for the same periods in the prior fiscal year. This represents an increase of $5.7 million, or 25%, for the quarter and $17.9 million, or 47%, year-to-date. The improvement was primarily driven by stronger demand in our Products category and higher rental utilization rates within the company’s Energy-as-a-Service (EaaS) revenue stream.

Second Quarter Fiscal 2026 Highlights:

• Gross profit for the second quarter of 2026 was $9.0 million, which was $2.0 million higher than the $7.0 million gross profit for the second quarter of fiscal 2025.
  • Gross margin was 32%, which was 100 basis points from 31% in the prior-year period.
  • The $2.0 million increase in gross profit was driven by favorable product mix including higher capacity product sales and stronger rental pricing.
  • Gross margin expansion reflected higher profitability across all revenue streams, supported by ongoing Design for Manufacturing and Assembly (DFMA) cost-out initiatives implemented throughout fiscal year 2025, which helped offset the additional cost for new tariffs on imports from China.
• The Company delivered net income of $0.8 million for the second quarter of fiscal 2026, compared to a net loss of $0.4 million for the second quarter of fiscal 2025.
  • The improvement was primarily driven by the $2.0 million higher gross profit and $0.9 million reduction in non-recurring professional expenses & bad debt in the quarter.
  • These gains were partially offset by higher product development expenses and increased incentive compensation costs associated with strong business performance.
• EPS from operations for the second quarter of fiscal 2026 was $0.04 per share, reflecting the Company’s strong operating results. This represents an EPS of $0.06 per share higher compared to a loss of $0.02 per share for the second quarter of fiscal 2025.
• After reflecting the accretion of preferred units required under the Hypothetical Liquidation at Book Value (HLBV) accounting method, reported EPS for the second quarter of fiscal 2026 was a loss of $0.89 per share.
• Adjusted EBITDA for the second quarter of fiscal 2026 was $4.5 million versus $3.8 million for the second quarter of fiscal 2025, due to a $1.2 million improvement in net income, partly offset by lower addbacks of non-recurring professional expenses.
• Total cash, including restricted cash was $7.7 million, as of September 30, 2025, representing a decrease of $1.0 million from March 31, 2025. The decrease was driven by higher working capital usage, primarily related to increases in accounts receivable and deferred revenue, partially offset by higher accounts payable.
• The Company continues to remain compliant with its financial covenants.

Second Quarter Year-to-Date Fiscal 2026 Highlights:

• Gross profit for the second quarter of 2026 year-to-date was $16.5 million, which was $5.7 million higher than the $10.8 million gross profit for the second quarter of fiscal 2025 year-to-date. Further, gross margin was 29%, which was an improvement of 1% over the 28% gross margin for the second quarter of fiscal 2025 year-to-date. The $5.7 million increase in gross profit was driven by increased sales of higher capacity products, overall product mix, as well as higher rental pricing. Gross margin improvement was primarily driven by higher profitability across all revenue streams, along with our DFMA cost-out initiatives implemented throughout fiscal year 2025, which offset the additional cost of new tariffs on imports from China.
• The Company delivered net income of $0.1 million for the second quarter of fiscal 2026 year-to-date, compared to a net loss of $4.4 million for the second quarter of fiscal 2025 year-to-date, primarily due to the $5.7 million higher gross profit and $2.2 million reduction in non-recurring professional expenses in the second quarter of fiscal 2026 year-to-date, which was partly offset by higher product development costs and incentive compensation costs.
• EPS from operations for the second quarter of fiscal 2026 year-to-date was $0.01 per share, which was $0.24 per share higher compared to a negative $0.23 per share for the second quarter of fiscal 2025 year-to-date. However, EPS was negative $0.93 per share for the second quarter of fiscal 2026 year-to-date after reflecting the accretion of preferred units as required by the HLBV accounting method.
• Adjusted EBITDA for the second quarter of fiscal 2026 year-to-date was $7.2 million versus $4.6 million for the second quarter of fiscal 2025 year-to-date, with the $2.6 million improvement primarily due to a $4.5 million improvement in net income, partly offset by lower addbacks of non-recurring professional expenses.
• Net cash used by operating activities was $1.0 million for the six months ended September 30, 2025, compared to $0.9 million provided by operating activities for the six months ended September 30, 2024. The $1.9 million increase in operating cash usage, despite improved net income of $4.4 million, was a result of changes in working capital, including a decrease in accounts payable and an increase in accounts receivable due to improved sales and higher factory protection plan claims versus shipments. Net cash provided by investing activities was $1.0 million for the six months ended September 30, 2025, compared to $0.2 million cash used by investing activities for the six months ended September 30, 2024. The $1.2 million change was primarily a result of the $1.4 million cash acquired in the acquisition of Cal Microturbine, net of the cash paid.
• Net cash used in financing activities was $1.0 million for the six months ended September 30, 2025, compared to $0.1 million for the six months ended September 30, 2024, mainly due to higher finance lease obligations payments.

“Capstone’s continued resilience and disciplined execution have driven our sixth consecutive quarter of positive Adjusted EBITDA, supported by solid growth in both product and rental revenues,” said John Miller, Interim Chief Financial Officer of Capstone. “Our improving financial health reflects the renewed confidence of our customers, coupled with significant operational improvements we’ve achieved over the past year.”

The global shift toward distributed generation plays directly to our strengths in fuel flexibility, high cycle efficiency, and low emissions. We’re turning years of innovation and operational discipline into real, scalable solutions that customers can depend on.

“Capstone today is a different company, more resilient, more focused, and ready to meet the moment,” said Vince Canino, President and CEO of Capstone. “This strong foundation, built on the strategic resilience of our Three Pillars of Strength strategy – Financial Health, Sustained Excellence, and Revitalization of Culture and Talent, positions Capstone to expand participation in two of the most dynamic markets shaping the global energy transition: microgrids and data centers. With continued focus on sustained excellence and financial discipline, we’re building a company positioned for sustainable growth and long-term value creation.”

Canino continued, “Our progress over the last six quarters reflects a business built on performance and purpose. As energy reliability, decarbonization without disruption, and electrification-driven growth accelerate, Capstone is positioned at the intersection of technology and transformation, delivering clean power where and when the world needs it most.”

Financial Tables to Follow

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 resulting 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. Merger and acquisition expense relates to expenses incurred for the acquisition of Cal Microturbine.

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.
