Risks

• Incurred a net loss of $2,124,027 during the six months ended June 30, 2025, and has a history of incurring losses, with no assurance of future profitability.
• Business is capital intensive, and products are built to order with customized configurations, leading to significant lead times and potential impact on profitability from changes in customer orders or lack of demand.
• Cash flows from operations are insufficient to fund the business, and the company has historically relied on financing from related parties.
• Material weakness in disclosure controls and procedures and internal control over financial reporting, specifically related to general controls over information technology, which could adversely affect financial reporting accuracy and timeliness, stock price, and access to capital markets.
• Failure to remediate identified material weaknesses in internal controls could lead to inaccurate financial reporting, sanctions from the SEC, restricted access to capital markets, and adverse effects on stock price.
• Regulatory push to eliminate fossil fuels in key markets (e.g., New York City) negatively impacts cogeneration unit sales, although the company believes its hybrid chiller products may have an advantage.
• Residual impacts of the COVID-19 pandemic continue to affect supply chains, causing delays, lack of critical component availability, and increased costs, impacting product and service margins.
• Higher energy prices for natural gas due to geopolitical tensions (Ukraine, Middle East) may affect the performance of the Energy Production Segment and the cost differential for cogeneration equipment.
• Increased cybersecurity risks and volatility related to commodity trading prices due to geopolitical tensions.

Future Outlook

The company intends to use the net proceeds from the recent public offering for continued product development, increased sales and marketing activities, additional human resources, capital expenditures, and anticipated expansion into the data center market, as well as for general working capital. The political environment following the 2024 US elections may favorably impact anti-fossil fuel sentiment and the regulatory environment. The company believes power-constrained customers, particularly data centers and industrial facilities, represent a significant growth opportunity for its chiller products and on-site power generation solutions. It also expects its products to run on Renewable Natural Gas (RNG) as it is introduced into the US gas pipeline infrastructure. The company is focusing on opportunities in low carbon Controlled Environment Agriculture (CEA) for its cogeneration equipment.

Management Comments

• Our service operation revenues grow with the sale of installed systems, since the majority of our product sales are accompanied by a service contract or time and materials agreements. As a result, our fleet of units being serviced by our service department grows with product sales.
• We believe that as regulations take into account scope 2 emissions and products like our hybrid chiller that can choose the cleanest fuel source will have a significant advantage in decarbonization efforts.
• Tecogen believes that these power constrained customers, in particular data centers and industrial facilities, represent a significant opportunity for growth.
• The customer need is driven by the ability to expand an existing facility or open a new facility quickly while taking advantage of utility expense savings long term.
• Our chiller products can reduce the electrical capacity needed on-site by 30% or more. Our InVerde product can provide on-site power generation which allows customers to eliminate long lead times associated with electrical switch gear and bridge any short fall in power from the utility.
• We have instituted a service price increase and have also been making engineering improvements to increase service intervals to increase gross margins.
• We believe that CEA offers an exciting opportunity to apply our expertise in clean cooling, power generation, and greenhouse gas reduction to address critical issues affecting food and energy security.

Industry Context

The company operates in the distributed generation and energy efficiency sector, focusing on natural-gas-fueled combined heat and power (CHP) systems, chillers, and heat pumps. It is strategically positioning itself to capitalize on the growing demand for data center cooling solutions, where its DTx chillers can reduce electrical capacity needs. The company also notes the impact of anti-fossil fuel sentiment in some key markets like New York City but believes its hybrid chiller technology, which can utilize the cleanest fuel source, will be advantageous for decarbonization efforts. Geopolitical tensions are noted for their potential impact on natural gas and electricity prices, which could affect the economic savings generated by the company's products. The company is also exploring opportunities in Controlled Environment Agriculture (CEA), leveraging its experience in energy-intensive indoor agriculture applications.

• Use net proceeds from the public offering for continued product development, increased sales and marketing activities, additional human resources, capital expenditures, and expansion into the data center market.
• Implement mitigating controls to address segregation of duties, hire additional staff, and implement additional controls for system access deficiencies.
• Implement additional controls over business operations and establish independent review and verification procedures for vendor and customer master files.
• Enhance documentation to support review occurrences and approval procedures.
• Commence regular periodic reviews of internal controls over financial reporting with the Board of Directors and Audit Committee.
• Conduct a comprehensive risk assessment to identify all potential risk areas and evaluate the adequacy of controls to mitigate these risks.

Key Dates

Recommendation

While Tecogen Inc. demonstrated strong revenue growth in its Products segment and successfully secured significant capital through a public offering, which addresses immediate liquidity concerns and funds future growth initiatives, the company continues to incur net losses. The overall gross margin percentage declined due to increased costs in the Services and Energy Production segments, and the Energy Production segment experienced a notable revenue decline. Furthermore, the identified material weakness in internal controls presents an operational risk that needs to be effectively remediated. The strategic focus on data centers and new product development is promising, but the company's ability to achieve sustained profitability and fully resolve its internal control issues remains to be seen. The recent capital raise provides a crucial lifeline and growth runway, but the underlying profitability challenges and governance concerns warrant a cautious 'hold' stance until more consistent positive financial trends and control improvements are evident.
