Ameresco and HA Sustainable Infrastructure Capital have agreed to spin off Ameresco's biofuels business into a newly formed joint venture called Neogenyx Fuels, valuing the new entity at a $1.8 billion post-money enterprise value. Ameresco will retain 70 percent ownership while HASI will hold 30 percent, with HASI committing $400 million to support the platform's growth. The agreement has been signed and the transaction is expected to close within the current quarter, marking one of the largest dedicated biofuels platform deals announced this year.

The structure is designed to unlock embedded value in Ameresco's biofuels portfolio while giving the business a dedicated capital partner with experience scaling sustainable infrastructure assets. Neogenyx Fuels will function as a developer, owner and operator of advanced fuel solutions, with renewable natural gas as its initial core product line. The joint venture brings together Ameresco's 25-year operating track record in biogas with HASI's investment platform, which currently manages more than $16 billion in sustainable infrastructure assets.

 

Capital Allocation and Transaction Structure

 

Of HASI's $400 million commitment, $300 million will flow directly into Neogenyx Fuels to fund organic growth, project development and pipeline expansion. The remaining $100 million will go to Ameresco as direct compensation for the contributed business, with the company indicating it will deploy those proceeds toward strategic opportunities, working capital and balance sheet deleveraging during the year. The cash injection gives Ameresco financial flexibility while preserving majority economic exposure to a business segment management views as a long-term growth driver.

From an accounting perspective, Ameresco will continue to consolidate Neogenyx Fuels on its balance sheet, meaning revenue figures will remain largely unchanged at the consolidated level. However, 30 percent of net income will be classified below the line as non-controlling interest attributable to HASI, which will reduce earnings attributable to Ameresco shareholders. Adjusted EBITDA, operating assets and assets in development metrics will reflect Ameresco's 70 percent ownership once the deal closes. The full value of Neogenyx Fuels' assets, liabilities and debt will sit on Ameresco's balance sheet, with HASI's equity stake recorded within shareholders' equity.

The Renewable Natural Gas Market Opportunity

 

The joint venture is being launched into a fast-expanding market for renewable natural gas. According to a 2025 ICF market study cited by the companies, RNG demand is projected to grow from approximately 139 to 153 million MMBtu per year today to as much as 612 million MMBtu per year by 2030. That implies a near-quadrupling of demand over a five-year window, driven by tightening low-carbon fuel standards, corporate procurement of low-carbon gas and rising emphasis on domestic energy supply security.

Emerging applications in sustainable aviation fuel, maritime shipping and international markets are expected to provide additional structural support for long-term RNG production economics. The combination suggests that biogas-derived fuels are moving beyond their traditional transport and utility customer base into harder-to-abate sectors where alternatives remain limited. For Neogenyx Fuels, this widening demand pool offers multiple commercial pathways for new project development beyond its core domestic markets.

 

Operating Capabilities and Project Pipeline

 

Once the transaction closes, Neogenyx Fuels is expected to rank among the largest developers of biogas projects in the United States, building on Ameresco's 25-year track record in greenfield development and long-term asset operation. The platform inherits a substantial development pipeline, which the companies say will support scalable infrastructure buildout, job creation and continued domestic leadership in next-generation fuels. Michael T. Bakas, who will lead Neogenyx Fuels as Chief Executive Officer, described the business as a next-generation platform for advanced biofuels capable of delivering resilient energy supply while building toward drop-in fuels, molecular products and other low-carbon solutions.

The platform's roadmap extends beyond conventional RNG into adjacent product categories that share underlying feedstock and processing economics. By concentrating engineering, operating and capital decisions within a dedicated joint venture, the partners aim to accelerate execution speed compared to running the business inside Ameresco's broader energy infrastructure portfolio.

Strategic Rationale for Both Partners

 

For Ameresco, the structure crystallises value in a high-growth segment of its business while retaining majority control and continued exposure to upside as the RNG market scales. Chief Executive Officer George P. Sakellaris said the combination of strategic focus and HASI's capital resources would enable Neogenyx Fuels to scale faster and deliver greater impact in a fast-growing market. For HASI, the deal extends a partnership with Ameresco that has spanned more than 60 joint transactions across multiple asset classes since 2001, deepening exposure to a sector where the firm sees sustained growth.

HASI President and Chief Executive Officer Jeffrey A. Lipson said the firm is confident in deploying capital with what he described as a best-in-class operator, citing expectations of continued RNG market expansion. The transaction effectively converts a long-running commercial relationship into a structural equity partnership, aligning incentives across development, financing and long-term asset performance. Guggenheim Securities advised Ameresco financially, with Kirkland and Ellis serving as legal counsel, while Lazard advised HASI with Gibson, Dunn and Crutcher acting as legal counsel.

 

Outlook for Advanced Biofuels Capital Formation

 

The Neogenyx Fuels transaction reflects a broader pattern in the energy transition where mature operating platforms are being recapitalised through specialist infrastructure investors to accelerate buildout. As demand for low-carbon fuels expands across transport, industry and aviation, the ability to combine technical execution with flexible long-duration capital is becoming a competitive advantage. Whether Neogenyx Fuels can convert its scale, pipeline and capital base into market leadership will depend on execution against the demand growth projected for the second half of the decade. The deal also signals continued institutional appetite for biogas-linked assets despite policy and pricing uncertainty in adjacent renewables segments.
