Future Outlook

Management is focused on improving products based on customer input, building brand awareness, and developing a diversified network of strategic distribution partners. The strategy targets products and solutions that drive repeatable business and larger deal sizes. Efforts are directed at monitoring operating expenses, improving manufacturing efficiencies, lowering direct material costs, and increasing average selling prices. Key drivers for success include higher average selling prices, lower direct material costs, positive new order flow, reduced cash usage, and expansion of the Energy-as-a-Service (EaaS) business. The company is developing Direct Current (DC) output power solutions for Electric Vehicle (EV) charging, collaborating on autonomous power solutions, and accelerating onboard remote monitoring systems. Significant research and development is dedicated to advancing the hydrogen product line, including testing a 100% hydrogen gas combustion system and qualifying a 100% hydrogen-fueled C200 engine.

Management Comments

• 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.
• Management expects to be able to lower our costs as product volumes increase.
• 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.

Industry Context

The company operates in the growing microgrid, energy efficiency, and renewable energy markets, which are driven by electrification demand, landfill gas, biodiesel, biogas, and critical power needs. The shift away from the volatile oil and gas market aligns with broader industry trends towards sustainable and resilient energy solutions. The development of hydrogen-fueled microturbines positions the company in an emerging clean energy sector. The Electric Vehicle (EV) charging market is also a significant growth area the company is targeting.

Comparison to Industry Standards

• The company positions itself as the market leader in microturbine energy systems based on the number of microturbines sold annually and total installed base.
• Microturbines are highlighted as outperforming conventional combustion engines in certain situations, such as when gas contains high sulfur, which can contaminate lube oil in conventional engines.
• Combined Heat and Power (CHP) and Combined Cooling, Heat and Power (CCHP) applications of microturbines can increase total system efficiency from approximately 30% to 85-90%, which is a strong efficiency claim compared to simple cycle generation.
• The company's technology offers a level of flexibility not currently offered by other technologies such as reciprocating engines.

Legal Proceedings

• Cal Microturbine Arbitration: Cal Microturbine filed a complaint seeking $25.0 million in damages, alleging breach of Distributor Agreement and fraud. The company counterclaimed for $20.0 million. A hearing is scheduled for September 2025, and settlement discussions are ongoing. The company issued a notice of intent to terminate the Distributor Agreement.
• Spitzer v. Flexon, Jamison, Juric, Robinson, and Hencken: A putative securities class action filed against certain current and former directors and officers, alleging violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934. A settlement agreement has been reached, and a final settlement hearing is set for November 13, 2025. Expenses up to the $1.3 million insurance deductible have been incurred or accrued.
• Mark Estrada and Ricardo Montalvo, vs. Capstone Green Energy LLC and Erick Kim: Two filings alleging pay violations by current and former non-exempt employees. The court compelled arbitration, determining arbitration agreements were enforceable and employees were not exempt.
• DV Energy, LLC vs Capstone Green Energy Holdings, Inc, et al.: Lawsuit seeking $0.7 million parts deposit due to U.S. sanctions. The Bankruptcy Court granted the company's motion to deposit $0.8 million as security, and Chapter 11 proceedings for the debtors have been closed. No remaining deposit liability as of June 30, 2025.

Related Party Transactions

• Services Agreement between Reorganized PrivateCo and Operating Subsidiary: Operating Subsidiary provides services to Reorganized PrivateCo, and Reorganized PrivateCo provides distributor support services. Operating Subsidiary pays Reorganized PrivateCo a service fee equal to 90% of Reorganized PrivateCo's income less itemized expenses. The company reported $0.5 million in DSS service fees in Other income, net, for Q1 2025.
• Trademark License Agreement: Reorganized PrivateCo grants the company a non-exclusive, royalty-bearing license to use Capstone Trademarks for an annual royalty of $100,000.

The company incurred $0.6 million in service fee expense for Q1 2025.

Stakeholder Impact

• Shareholders: Potential for increased value due to improved financial performance and backlog, but significant risk from 'going concern' doubt, need for capital, and ongoing litigation. Delisting from Nasdaq and trading on OTC market impacts liquidity.
• Employees: Ongoing legal proceedings regarding pay violations (Estrada and Montalvo) could impact employee relations and compensation practices.
• Customers: Stronger product offerings (hydrogen, DC solutions) and improved service plans (FPP) could benefit customers. However, the dispute with Cal Microturbine, a significant distributor, could disrupt sales channels.
• Creditors: The 'going concern' doubt and need for refinancing the New Money Note by December 2025 pose risks. Compliance with covenants is critical.
• Suppliers: Efforts to reduce material costs and potential challenges in transitioning from single-source suppliers could impact supplier relationships.

Next Steps

• Continue process improvement workstreams to drive operational and financial performance.
• Implement cost reduction in products, services, and operating expenses.
• Pursue margin expansion through price increases.
• Execute sales volume initiatives to improve liquidity.
• Remediate the material weakness in internal control over financial reporting related to FPP service contracts.
• Continue R&D programs for new product development and product enhancements, including DC output power solutions, autonomous power solutions, remote monitoring systems, and hydrogen product line advancements.
• Engage in financing discussions to refinance the New Money Note and add additional liquidity.
• Participate in the Cal Microturbine arbitration hearing scheduled for September 2025 and ongoing settlement discussions.
• Attend the final settlement hearing for Spitzer v. Flexon, et al. on November 13, 2025.
• Monitor and address new accounting pronouncements (ASU No. 2023-09 and ASU No. 2024-03).

Key Dates

Recommendation

While Capstone Green Energy demonstrated significant improvements in revenue growth and a narrowed net loss, along with a strong backlog, the persistent 'going concern' warning and the need for additional liquidity by December 2025 introduce substantial uncertainty. The identified material weakness in internal controls and ongoing significant legal disputes also weigh heavily. The positive operational momentum is offset by these critical financial and governance risks, making a 'hold' recommendation appropriate for investors to monitor the company's ability to address its liquidity challenges and remediate internal control deficiencies before considering further investment.
