• Sales, or the perception of sales, of a substantial number of securities by selling securityholders could cause the price of Class A Common Stock and Warrants to fall.
• Certain existing securityholders purchased securities at prices below current trading prices and may experience positive returns even if future investors do not.
• Management team has limited experience managing a public company, and regulatory compliance obligations may divert attention.
• Significant costs are incurred as a result of operating as a public company.
• Material weaknesses in internal controls over financial reporting could lead to inaccurate or untimely financial reporting.
• Nasdaq may delist the company's securities from trading.
• An active, liquid market for securities may not develop, affecting liquidity and price.
• Warrants exercisable for Class A Common Stock would increase shares eligible for future resale and result in dilution.
• The company may redeem unexpired Warrants prior to their exercise at a disadvantageous time for holders.
• As a holding company, dependence on distributions from OpCo to pay taxes, TRA payments, and overhead expenses is a risk.
• Payments under the Tax Receivable Agreement (TRA) could be significant, accelerated, and potentially exceed actual tax benefits, and may not be reimbursed if tax benefits are disallowed.
• If OpCo were to become a publicly traded partnership, it could lead to significant tax inefficiencies and inability to recover TRA payments.
• Tax distributions to OpCo unitholders may be substantial and affect liquidity.
• Substantial costs incurred in connection with the Mergers could adversely affect financial condition and results of operations.
• Failure to realize all anticipated benefits of the Merger or longer-than-expected realization time.
• Inability to compete effectively post-Merger could materially and adversely affect results of operations.
• Combined company stockholders may experience dilution from future equity issuances.
• Ability to use net operating loss (NOL) carryforwards and other tax attributes may be limited due to ownership changes.
• Business operations are subject to various and changing federal, state, local, and foreign laws and regulations that could result in costs or sanctions.

Future Outlook

The company plans to increase market impact and grow revenue and profits by expanding into additional geographic markets, both organically and through M&A, focusing on areas with favorable electricity rates and incentives. It intends to increase capacity by investing in personnel and systems, grow its external dealer sales channel, and expand customer options for affordable solar energy, including roofing services and leasing options. Management expects a period of regulatory and policy uncertainty in the near term, particularly regarding tariffs and trade regulations. The company anticipates continued operating losses and significant cash outflows for at least the next few years, but believes proceeds from the Heliogen business combination will be sufficient for the next twelve months.

Industry Context

The solar energy industry is highly competitive and continually evolving, facing challenges from electric utilities, retail electric providers, and other renewable energy companies. Government policies, including tax credits and net metering, significantly influence the market, but are subject to change, as evidenced by the recent Pub. L. No. 119-21 removing the Section 25D credit after December 31, 2025. The industry is also impacted by supply chain disruptions, tariffs on imported components, and fluctuating interest rates affecting consumer financing. The company's expansion into new states and its merger with Heliogen, a concentrated solar energy technology company, reflect a strategy to diversify offerings and scale operations in a dynamic market, despite Heliogen's prior cost-reduction measures and going concern issues.

Comparison to Industry Standards

• The company's gross margin of 47.0% in 2024 and 53.5% in H1 2025 shows an improvement in cost efficiency relative to revenue, which could be a positive differentiator against competitors, especially given the challenging market.
• The significant decline in revenue (33.2% in 2024, 23.0% in H1 2025) and shift to net losses and negative Adjusted EBITDA contrasts with a growing renewable energy market, suggesting underperformance relative to industry growth trends, possibly due to specific operational or financing challenges.
• The reliance on third-party leasing companies for 63% of installations in 2024, with a related party (White Horse Energy, owned by the CEO) managing 30% of these, indicates a business model that may be more susceptible to financing market conditions and related-party risks compared to companies with more diversified or internal financing capabilities.
• Heliogen's prior decision to halt construction of the commercial-scale concentrated solar energy facility in Mojave, California, and its Texas steam plant, along with facility closures, suggests that its concentrated solar power technology faced significant commercialization hurdles and cost escalation, potentially indicating a challenging integration for Zeo Energy compared to more mature, commercially proven technologies in the broader solar industry.

Stakeholder Impact

• Shareholders face significant dilution risk from the registration of 50,727,996 shares for resale by selling securityholders, representing over 92% of outstanding shares, and potential future equity issuances.
• Shareholders are exposed to substantial financial risk due to declining revenues, increased net losses, negative Adjusted EBITDA, and critically low cash balances, as well as going concern warnings from auditors.
• Employees and service providers are impacted by the company's need to hire, train, deploy, manage, and retain a substantial number of skilled personnel to support growth, with competition for qualified personnel increasing.
• Customers may experience delays in solar system installations due to supply chain disruptions, technical/regulatory interconnection limitations, and potential issues with subcontractor performance.
• Customers' financial benefits from solar energy systems are sensitive to changes in government incentives (e.g., Section 25D tax credit phase-out) and utility rate structures (e.g., net metering policies).
• Creditors, particularly those involved in the Lumio Promissory Note and the Solar Leasing loan guaranteed by Zeo, face risks related to the company's liquidity and financial performance.

Next Steps

• Expand operations into additional geographic markets, both organically and through strategic M&A.
• Increase capacity for efficient growth by investing in people and systems, including growing and training the internal seasonal sales force and increasing external dealers.
• Expand the roofing business in certain markets to facilitate solar installations.
• Expand customer options for buying affordable solar energy, including leasing programs.
• Remediate identified material weaknesses in internal controls over financial reporting, including designing risk assessment processes, enhancing review of accounting transactions, improving internal control policies, implementing IT system controls, and hiring additional accounting and financial personnel.
• Continue to assess the impact of new U.S. government tariffs and trade policies on procurement and pricing strategies.
• Monitor and manage the Lumio Promissory Note milestones for Tranche 2 (340 permits) and Tranche 3 (296 installations) within the extended 120-day periods.
• Address the substantial doubt about the ability to continue as a going concern, as noted by auditors for both Zeo Energy and Heliogen.

Key Dates

Recommendation

The filing reveals a company in severe financial distress, marked by substantial and increasing net losses, negative Adjusted EBITDA, and critically low cash reserves. The auditor reports for both Zeo Energy and its recently acquired subsidiary, Heliogen, explicitly raise 'substantial doubt about its ability to continue as a going concern.' While strategic acquisitions have occurred, the financial performance has deteriorated significantly post-acquisition, with revenues declining sharply. The registration of over 92% of outstanding shares for resale by selling securityholders, coupled with potential future equity raises and high-cost related-party debt, indicates significant impending dilution and downward pressure on the stock price. Material weaknesses in internal controls further compound the risk. Given the dire financial health, going concern warnings, and high dilution risk, a seasoned investor would likely recommend a strong sell.
