Here are the 10-K annual reports from OPAL Fuels Inc. (OPAL) in our archive since June 2025, newest first, and each one links through to the document itself with the summary and the scores our analysis gives it.

OPAL Fuels Inc. files its Annual Report describing a vertically integrated business that captures biogas from landfills and dairies and converts it into renewable natural gas (RNG) and renewable power for transportation and utility markets in the United States.
The company’s main revenue comes from selling environmental credits such as RINs, LCFS credits, ISCC Carbon Credits and RECs generated when RNG is used as vehicle fuel. In 2025 it dispensed 74 million gasoline gallon equivalents of RNG and operated 27 projects: 12 RNG plants with 9.1 million MMBtus per year of design capacity and 15 renewable power facilities totaling 105.8 MW.
OPAL outlines growth plans through additional RNG projects under construction, converting selected power plants to RNG, expanding fueling stations, and entering hydrogen fueling. Key risks center on dependence on long-term gas rights, regulatory incentives, environmental compliance, third-party pipelines and utilities, and volatility in prices for fuels and environmental attributes.
