Risk factors and legal proceedings
The risks Montauk Renewables, Inc. names in Item 1A of its 10-K filed Mar 11, 2026: 41 risks under these headings, as written.4
- Operational Risks
- Our renewable energy projects may not generate expected levels of output.
- The concentration in revenues from five of our projects and geographic concentration of our projects expose us to greater risks of production interruptions from severe weather or other interruptions of production or transmission.
- We have significant customer concentration, with a limited number of customers accounting for a substantial portion of our revenues.
- Our projects are not able to insure against all potential risks and may become subject to higher insurance premiums.
- Competition Risks
- We may face intense competition and may not be able to successfully compete.
- Our success depends, in part, on technological innovation to stay ahead of market competitors.
- Our use and enjoyment of real property rights for our projects may be adversely affected by the rights of lienholders and leaseholders that are superior to those of the grantors of those real property rights to our projects.
- We may not be able to obtain long-term contracts for the sale of power produced by our projects on favorable terms and we may not meet certain milestones and other performance criteria under existing PPAs.
- Business Strategy Risks
- Our commercial success depends on our ability to identify, acquire, develop and operate individual renewable energy projects, as well as our ability to maintain and expand production at our current projects.
The other 32 risks
- If there is not sufficient demand for renewable energy, or the associated Environmental Attributes, or if renewable energy projects do not develop or take longer to develop than we anticipate, we may be unable to achieve our investment objectives.
- Our fuel supply agreements with site hosts have defined contractual periods, and we cannot assure you that we will be able to successfully extend these agreements at their historic revenue levels or at all.
- Our agreements contain complex price adjustments, calculations and other terms based on gas price indices and other metrics, the interpretation of which could result in disputes with counterparties that could affect our results of operations and customer relationships.
- In order to secure contracts for new projects, we typically face a long and variable development cycle that requires significant resource commitments and a long lead time before we realize revenues.
- We plan to expand our business in part through developing RNG recovery projects at landfills and livestock farms, including our Turkey, North Carolina location, but we may not be successful.
- Our dairy farm project has, and any future digester project will have, different economic models and risk profiles than our landfill facilities, and we may not be able to achieve the operating results we expect from these projects.
- While we currently focus on converting methane into renewable energy, in the future we may decide to expand our strategy to include other types of projects. Any future energy projects may present unforeseen challenges and result in a competitive disadvantage relative to our more established competitors.
- The profitability of our renewable fuel projects may be limited by our ability to dispense fuel to separate RINs and the volatility of the price of RINs.
- Our revenues may be subject to the risk of fluctuations in commodity prices.
- We are exposed to the risk of failing to meet our contractual commitments to sell RINs from our production.
- Regulatory Risks
- The reduction or elimination of governmental economic incentives for renewable energy projects or other related policies could adversely affect our business, financial condition and results of operation.
- We may be unable to obtain, modify or maintain the regulatory permits, approvals and consents required to construct and operate our projects.
- Negative attitudes toward renewable energy projects from the U.S. government, other lawmakers and regulators, and activists could adversely affect our business, financial condition and results of operations.
- Revenue from any projects we complete may be adversely affected if there is a decline in public acceptance or support of renewable energy, or regulatory agencies, local communities, or other third parties delay, prevent, or increase the cost of constructing and operating our projects.
- Existing regulations and policies, and future changes to these regulations and policies, may present technical, regulatory and economic barriers to the generation, purchase and use of renewable energy, and may adversely affect the market for credits associated with the production of renewable energy.
- In order to benefit from RINs and LCFS credits, our RNG projects are required to be registered and are subject to regulatory audit.
- Cybersecurity and Information Technology Risks
- A failure of our IT and data security infrastructure could have a material adverse effect on our business and operations.
- Our business could be negatively affected by security threats, including cybersecurity threats and other disruptions.
- Third-Party Partner Risks
- Failure of third parties to manufacture quality products or provide reliable services in a timely manner could cause delays in developing and operating our projects, which could damage our reputation, adversely affect our partner relationships or adversely affect our growth.
- Our projects rely on interconnections with and access to electric distribution and transmission facilities and gas transportation pipelines that are owned and operated by third parties, and as a result, are exposed to risks related to such facilities’ development and operational curtailment risks.
- We are dependent upon our relationships with Waste Management and Republic Services for the operation and maintenance of landfills on which several of our RNG and Renewable Electricity projects operate.
- Capital and Credit Risks
- Our senior credit facility may not be sufficient to meet our financial needs and contains financial and operating restrictions that may limit our business activities and our access to other forms of credit.
- We may be required to write-off or impair capitalized costs or intangible assets in the future or we may incur restructuring costs or other charges, each of which would harm our earnings.
- Emerging Growth Company Risks
- We are in our last year of being an emerging growth company and will soon be required to comply with certain requirements that apply to other public companies.
- If we identify material weaknesses in the future or otherwise fail to maintain an effective system of internal controls, we may be unable to accurately or timely report our financial condition or results of operations, which may adversely affect our business.
- Common Stock Risks
- Our shares of common stock may trade on more than one market and this may result in price variations.
- Future sales of our common stock in the public market could cause the market price of our common stock to decline.
- We are a “controlled company” within the meaning of the Nasdaq rules and, as a result, qualify for, and intend to rely on, exemptions and relief from certain governance requirements.
- The concentration of our capital stock ownership may limit our stockholders’ ability to influence corporate matters and may involve other risks.
- Certain of our directors reside outside of the United States and it may be difficult to enforce judgments against them in the United States.
- General Risk Factors
- If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our share price and trading volume could decline.
- We are highly dependent on our senior management team and other highly skilled personnel, and if we are not successful in attracting or retaining highly qualified personnel, we may not be able to successfully implement our business strategy.
Legal proceedings
From time to time we and our subsidiaries may be parties to legal proceedings arising in the normal course of our business. We and our subsidiaries are currently not a party, nor is our property subject, to any material pending legal proceedings. None of our directors, officers, affiliates, or any owner of record or beneficial owner of more than 5% of our common stock, is involved in a material proceeding adverse to us or our subsidiaries or has a material interest adverse to us or our subsidiaries.
