Industry Context

This announcement highlights the ongoing growth and financial structuring within the renewable natural gas (RNG) sector, a key component of the broader clean energy and sustainable transportation fuels industry. Gevo's focus on dairy-based anaerobic digestion aligns with efforts to reduce agricultural emissions and produce low-carbon fuels, particularly relevant in markets like California with strong Low Carbon Fuel Standard (LCFS) incentives. The refinancing demonstrates a trend towards optimizing capital structures for renewable energy projects, leveraging tax-exempt bonds and non-recourse financing to support expansion and improve corporate liquidity. The high carbon intensity score achieved by Gevo RNG positions it favorably within the LCFS market, indicating strong potential for generating valuable environmental credits.

Comparison to Industry Standards

• The carbon intensity score of negative 339 gCO2e/MJ for Gevo RNG's product is exceptionally low and significantly better than typical fossil natural gas, which has a positive carbon intensity. This score is among the lowest in the industry for RNG projects, particularly those utilizing agricultural waste like dairy manure, making it highly competitive for generating LCFS credits in California.
• The non-recourse nature of the $40 million bonds is a standard financing structure for project finance in the renewable energy sector, limiting the financial exposure of the parent company (Gevo, Inc.) to the specific project assets and cash flows.
• The interest rates of 8.125% and 8.500% for the new bonds are higher than typical investment-grade corporate debt but may be considered reasonable for project finance bonds, especially given the non-recourse nature and the specific risks associated with renewable energy projects.

Stakeholder Impact

• Shareholders: Benefit from improved balance sheet liquidity, reduced financial risk (non-recourse debt), and potential for future growth and profitability from the RNG business.
• Employees: Continued operation and potential expansion of the RNG project could support existing jobs and create new ones, particularly in rural communities where Gevo operates.
• Customers: Continued supply of renewable natural gas as a sustainable alternative to fossil fuels, particularly in the transportation sector.
• Creditors: The refinancing provides a more stable capital structure for the subsidiary, potentially improving the credit quality of the remaining existing bonds and the new bonds.
• Regulatory Authorities: The project's high carbon intensity score and GHG emissions reductions align with regulatory goals for environmental sustainability.

• Refinance the remaining balance of the Series 2021 Green Bonds through the issuance of an additional series of 2025 Bonds.
• Explore increased scaling opportunities for the Renewable Natural Gas (RNG) business.
