Risks

• The profitability is highly dependent on the market price of Environmental Attributes, including RINs.
• Delays in landfill host installation of wellfield collection infrastructure are impacting feedstock gas projections and production increases.
• Wellfield extraction environmental factors continue to impact gas extraction at the Apex site, potentially lengthening periods of excess capacity.
• Changes at the McCarty facility's wellfield collection system have led to elevated nitrogen in feedstock and reduced quantity of feedstock received.
• The company is subject to regulatory changes in federal and state programs supporting renewable fuels, which could impact incentives.
• The Montauk Ag Renewables project faces potential impacts from ongoing negotiations and regulatory changes in North Carolina.
• The company's reliance on third parties for product manufacturing and landfill operations presents a risk.
• Concentration of revenues from a small number of customers and projects poses a risk.

Future Outlook

The company anticipates continued growth through development and acquisitions, with significant capital expenditures planned for new RNG and CO2 facilities. The new senior credit facility is expected to provide financial flexibility for these developments. Management believes they will have sufficient cash flows and borrowing availability to meet obligations for the next 12-24 months.

Management Comments

• We believe that our business model and technology are highly scalable given availability of biogas from agriculturally derived sources, which will allow us to continue to grow through prudent development and complimentary acquisitions.
• We believe that our credit refinancing with HASI will provide us the ability to secure additional project-based financing for our current development projects.
• We believe that our existing cash and cash equivalents, cash generated from operations, and credit availability under our New Senior Credit Facility will meet our interest-only debt service obligations and anticipated required capital expenditures (including for projects under development) for the next 12 to 24 months.

Industry Context

StockSavvy.ai notes that Montauk Renewables operates in the growing renewable energy sector, specifically focusing on RNG and Renewable Electricity. The company benefits from government incentives like the RFS and LCFS programs, which are critical drivers for the industry. However, the industry is also subject to regulatory changes and market volatility in environmental attribute pricing.

Comparison to Industry Standards

• The company's RNG production volumes are significant, positioning it as one of the largest U.S. producers of RNG.
• The average D3 RIN index price for Q2 2026 was $2.54, which is a key benchmark for RNG producers.
• The company's new senior credit facility interest rate of 10.25% is a relevant metric for evaluating financing costs in the industry.
• The company's development pipeline includes projects like the Bowerman RNG Facility with an estimated capacity of 3,600 MMBtu/day and an estimated capital expenditure of $85,000-$95,000, which can be compared to similar projects by competitors.
• The company's strategy to expand into agricultural feedstock, such as dairy and swine farms, aligns with industry trends seeking higher value environmental attributes (e.g., lower CI scores).

Legal Proceedings

• Management does not believe there are any material pending legal proceedings that would have a material adverse effect on the company's financial position or results of operations as of June 30, 2026.

Related Party Transactions

• The company has a loan agreement with Montauk Holdings Limited (MNK), an affiliate, with a current principal balance of $10.69 million, due December 31, 2033.
• The company consolidated MNK as a variable interest entity on December 31, 2024, resulting in the elimination of intercompany loans and investments in consolidation.

Stakeholder Impact

• Shareholders may benefit from increased revenues and a return to profitability, alongside the company's growth initiatives.
• Creditors are impacted by the new senior credit facility and the company's ability to meet its financial covenants.
• Suppliers and site hosts will continue to be impacted by royalty payments and fuel supply agreements, which are typically long-term.
• Employees may be impacted by the company's growth and development plans, as well as potential changes in stock-based compensation.

Next Steps

• Continue development of ongoing growth projects including Bowerman RNG Facility, Atascocita LCO2 Facility, Tulsa RNG Facility, and Rumpke RNG Relocation Project.
• Finalize offtake agreements for the Atascocita CO2 project.
• Complete programming modifications for electrical switchgear at the Turkey, North Carolina facility by mid-August.
• Continue farm site collection equipment installations for the Montauk Ag Renewables project during the second half of 2026.

Key Dates

Recommendation

The company shows strong revenue growth and a return to profitability, supported by a new credit facility and a robust development pipeline. However, the increase in operating expenses, ongoing project delays, and reliance on volatile environmental attribute pricing warrant a cautious 'hold' rating until execution risks are further mitigated and project timelines become more certain.
