Risks

• Limited cash, history of losses, and expectation of continued operating losses and negative cash flows in the near future.
• Ability to successfully develop and implement technologies and achieve profitability.
• Limited operating history.
• Ability to maintain Nasdaq listing, including compliance with the Bid Price Rule and stockholder equity requirements.
• Changes in government regulations that could substantially reduce, or even eliminate, the need for our technology.
• Emerging competition and rapidly advancing technology in our industry that may outpace our technology.
• Customer demand for the products and services we develop.
• Impact of competitive or alternative products, technologies, and pricing.
• Ability to manufacture any products we design.
• General economic conditions and events and the impact they may have on us and our potential customers.
• Impact of global supply-chain constraints and the threat of, or implementation of, tariffs on imported or exported goods and materials.
• Revenue has been highly concentrated among a small number of customers, and results of operations could be harmed if a key revenue source is lost and not replaced.
• Impact of a cybersecurity incident or other technology disruption.
• Ability to protect intellectual property.
• Ability to obtain adequate financing in the future, especially given capital market volatility and limitations from 'baby shelf rules' on equity issuance.
• Lawsuits and other claims by third parties or investigations by various regulatory agencies.
• Ability to retain and hire personnel with the experience and talent to develop products and business.
• Limited authorized shares of common stock available for issuance, restricting future equity financing.
• Adverse judgments or settlements in legal proceedings could materially harm the business, financial condition, operating results, and cash flows.

Future Outlook

We expect to experience operating losses and negative cash flow for the foreseeable future. We may need to raise additional capital, but capital market volatility could negatively affect this ability. Successful growth depends on market recognition and acceptance of technologies, and securing adequate funding through co-development agreements, strategic partnering, or equity/debt financing. We intend to regain Nasdaq compliance by effecting a reverse stock split, if necessary. There is no assurance that our technologies will be accepted, that we will earn sufficient revenues to support operations, or that we will ever be profitable. If funds cannot be raised as needed, operations may be scaled back or ceased.

Management Comments

• "We have incurred losses since inception totaling $104.2 million and we expect to experience operating losses and negative cash flow for the foreseeable future."
• "We believe we have sufficient cash and expected cash collections to fund current operating expenses for over twelve months."
• "Until the growth of revenue increases to a level that covers our operating expenses, we intend to continue to fund operations in this manner [equity offerings], although the volatility in the capital markets may negatively affect our ability to do so."
• "There can be no assurance that we will be successful in achieving our long term plans, or that such plans, if consummated, will result in profitable operations or enable us to continue in the long term as a going concern."
• "There can be no assurance that our technologies will be accepted, that we will ever earn revenues sufficient to support our operations, or that we will ever be profitable."
• "We have no committed source of financing, and we cannot assure that we will be able to raise money as and when we need it to continue our operations."

Industry Context

The company operates in the decarbonization and industrial combustion systems market, focusing on emission reduction and energy efficiency. This aligns with global trends towards stricter environmental regulations and demand for cleaner industrial processes. The development of an ultra-low NOx hydrogen burner is particularly relevant given the increasing focus on hydrogen as a clean fuel source. However, the company's limited revenue and ongoing losses suggest it is still in the early commercialization phase, facing challenges in gaining market acceptance and scaling operations within a competitive and capital-intensive industry.

Comparison to Industry Standards

• The filing does not provide specific comparable company or project data to assess against global benchmarks.
• The company's financial performance, characterized by significant losses and declining revenue, indicates it is still in a pre-commercial or early commercialization stage, which is common for technology development companies but contrasts sharply with established, profitable industry players in the industrial combustion or environmental technology sectors.

Management Changes

Corporate Governance

Legal Proceedings

• Not a party to any material pending legal proceedings or claims believed to have a material adverse effect on the business, financial condition, or operating results.
• Incurred approximately $131 thousand in legal fees pertaining to a regulatory inquiry by the SEC into the trading of securities in 2020.
• Incurred approximately $435 thousand in legal fees for the Special Committee.
• Accrued $22 thousand for reimbursement of certain legal fees incurred by the Clarkson Parties and DiGiandomenico Parties in connection with Cooperation Agreements.

Related Party Transactions

• Issued 15,000 shares to Firm IR Group LLC (investor relations firm) in quarterly installments for services rendered, pursuant to the 2013 Consultant Stock Plan.
• Issued 87,016 shares of common stock to Firm IR at a fair market value price per share of $0.58 for reimbursement of certain legal fees incurred by Firm IR.

Stakeholder Impact

• Shareholders: Significant revenue decline, increased losses, and Nasdaq delisting risk could negatively impact share price and investment value. Potential dilution from future equity raises. Board changes and cooperation agreements reflect shareholder activism.
• Employees: Continued operating losses and potential scaling back of operations if funding is insufficient could impact job security. Share-based compensation is a significant component.
• Customers: Customer project delays can impact performance obligations. The company's financial instability could raise concerns about long-term viability and support for its technologies.
• Creditors: No contractual debt obligations, which is positive, but declining cash and ongoing losses could affect future creditworthiness if debt financing is pursued.
• Suppliers: No specific impact mentioned, but general financial health could affect payment terms or relationships.

Next Steps

• Regain compliance with Nasdaq's $1 minimum bid price rule by March 30, 2026, potentially through a reverse stock split.
• Continue efforts to develop and commercialize ClearSign Core technology and other solutions.
• Seek additional funding through co-development agreements, strategic partnering, or equity/debt financing.
• Continue to pursue intellectual property protection.
• Assess the impact of new accounting standards (ASU 2023-09, ASU 2024-03, ASU 2025-04, ASU 2025-05) on financial statements and disclosures.

Key Dates

Recommendation

The company faces severe financial challenges, including a near 50% revenue decline, increased net losses, and dwindling cash reserves. The Nasdaq delisting notice, requiring a potential reverse stock split, signals significant operational and market confidence issues. While the company has an ATM program and warrants, its history of losses, limited operating history, and dependence on future capital raises in a volatile market present substantial risks. The overall outlook is highly uncertain, making the stock a high-risk investment with significant downside potential.
