1. Company Overview and Business Model

Capstone Green Energy Holdings develops, manufactures, sells, and services microturbine-based distributed power generation systems. Its core technologies and business lines include:

• Microturbine Products & CHP/CCHP/ICHP: Inverter-based, oil-free turbines ranging from 65 kW to 1 MW per unit. They generate electricity and recover waste heat for heating, cooling and process steam (combined heat and power).
• Factory Protection Plans (FPP): Extended service and maintenance contracts that cover parts and labor for multi-year periods.
• Energy-as-a-Service (EaaS): Four financing models – rental, BOOM (Build-Own-Operate-Maintain), PPAs and lease-to-own – designed to lower barriers to adoption.
• Services & Accessories: Aftermarket parts sales, remote monitoring, and turnkey system integration.
• Emerging Hydrogen Solutions: Early-stage R&D on 100% hydrogen microturbine operation, with prototypes running on 30% blends.

Vertical markets include energy efficiency (CHP/CCHP), renewable fuels (landfill/wastewater biogas), oil & gas (flare gas capture), critical power, and microgrids. Sales occur through a global network of 53 distributors and OEM partners.

2. Segment & Geographic Revenue Mix

Fiscal 2025 revenue of $85.6 million declined 6% from $91.2 million in 2024. Segment mix:

• Energy Efficiency (CHP/CCHP): 51% (+14 pts YoY)
• Natural Resources & Oil & Gas: 31% (–3 pts)
• Renewable Fuels: 8% (–11 pts)
• Critical Power & Microgrids: 10%
• Transportation/EV Charging: 0%

Geographic breakdown:

• North America: 69%
• Europe: 13%
• Asia & Australia: 10%
• Latin America: 11%
• Middle East & Africa: <1%

North America and emerging rental/EaaS activity helped offset declines in Europe, driven by high gas costs and project delays.

3. 2025 Financial Highlights

Metric	2025	2024	% Change
Revenue	$85.6 M	$91.2 M	–6%
Gross Profit	$23.3 M (27% margin)	$14.3 M (16% margin)	+63%
Net Income (Loss)	–$7.2 M	+$7.4 M	N/A
Cash Flow from Ops	+$7.7 M	–$27.7 M	——

Gross margin improvement was driven by:

1. Pricing increases implemented in early 2024.
2. Cost-out initiatives and supplier negotiations.
3. Higher margins on rental fleets (35% vs. 19% in 2024).

Operating expenses decreased $6.0 M to $28.9 M (34% of revenue) as legal, sponsor and restructuring costs normalized. R&D remained 3% of revenue.

Cash flow turned positive as inventory and A/R were managed more effectively, and the bankruptcy-related non-cash losses no longer depressed cash flow.

4. Balance Sheet & Liquidity

• Cash: $8.7 M
• Working capital deficit: –$16.5 M
• Exit facility debt: $32.2 M principal (term SOFR + 7%; maturities Dec 2025 & 2026)
• Credit Facility: $0 under access
• Inventory: $20.1 M (lower-of-cost-or-net realizable value)

On December 7, 2023, the company emerged from Chapter 11 with a debt-for-equity swap:

• Pre-petition secured & DIP debt (~$53 M) settled for all equity of a private holding entity.
• Operating Subsidiary issued 10.45 M non-dilutable preferred units and 18.54 M common units.

A restrictive exit note requires minimum liquidity and adjusted EBITDA covenants, with a six-month waiver on some financial tests.

Going Concern: Management disclosed substantial doubt due to the working capital deficit, debt maturities, and limited access to capital markets.

5. Key Risks & Challenges

1. High Leverage & Repayment Risk: $32 M exit debt due Dec 2025/2026. Refinancing risk is real.
2. Going Concern: Substantial doubt about continuity; requires debt covenant compliance and new capital.
3. Narrow Trading: OTC liquidity is thin; bid/ask spreads can be wide.
4. Oil & Gas Exposure: Natural resources market fluctuates with commodity prices.
5. Technological Competition: Fuel cells, batteries, reciprocating engines, solar+storage.
6. Concentrated Customers & Suppliers: Top 3 distributors >35% of revenues.
7. Internal Controls: Material weakness on service contract accounting.
8. Regulation & Incentives: ITC changes, tariffs, emissions rules, hydrogen incentives.

6. Outlook & Valuation Considerations

Positive drivers:

• Higher gross margins, pricing power
• Growing rental/EaaS business
• Expanding CHP/CCHP market under decarbonization mandates
• Hydrogen R&D partnerships (Argonne, UCI)

Negative headwinds:

• Liquidity constraints & debt maturities
• Reliance on OTC liquidity
• Capital-intensive growth model
• Competing LEAN/microgrid solutions
• Debt covenants and potential for default

Valuation:

• At $0.75/share and 18.6 M shares, market cap ~ $14 M.
• Enterprise value is heavily leveraged.
• No consensus EBITDA multiple—stock is trading on far-out risk/reward.

Given the narrow market, late-cycle go-public, ongoing covenant risk, capex needs, and negative net worth, this equity is a high-risk, low-liquidity play.

7. Investment Score: 3.5/10

Capstone Green Energy offers leading microturbine & CHP technology with improved margins and a growing EaaS presence. However, high leverage, going concern risk, limited liquidity, and execution of growth plans under tight capital raise hurdles make it a speculative, high-risk investment.

Score Breakdown (1–10 scale):

• Technology & IP 4
• Market Potential (CHP, hydrogen) 
• Execution & Operations 
• Financial Strength 
• Liquidity & Share Trading
  

Overall: 3.5 /10

Investors seeking a turnaround play with hydrogen optionality and macro decarbonization trends may find CGEH intriguing but must be ready to stomach execution risk and limited liquidity.
