Gevo, Inc. Segments Disclosure

26. Segments

Operating segments are defined as components of an entity for which discrete financial information is available that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s Chief Executive Officer is the CODM. The CODM assesses the segments’ performance by using Loss from Operations.

The CODM uses operating results for each segment predominantly in the annual budget and forecasting process. The CODM considers budget-to-actual variances on a quarterly basis when making decisions about the allocation of operating and capital resources of each segment. As such, management has determined that the Company has organized its operations and activities in the manner in which information is utilized by the CODM and has determined that it has four operating and reportable segments: (i) Gevo segment; (ii) GevoFuels segment; (iii) GevoRNG segment and (iv) GevoND segment. All segments follow the same basis of accounting policies as described in Note 2, Summary of Significant Accounting Policies.

Gevo segment. The Gevo segment is responsible for all research and development activities related to the future production of SAF, commercial opportunities for other renewable hydrocarbon products, such as hydrocarbons for gasoline blendstocks and diesel fuel; ingredients for the chemical industry, such as ethylene and butenes; plastics and materials; and other chemicals. The Gevo segment also develops, maintains and protects its intellectual property portfolio, provides corporate oversight services, and is responsible for development of Verity platforms.

GevoFuels segment. GevoFuels is a cornerstone of the Company’s operations, committed to driving low-cost, sustainable, and American-made energy solutions. Our focus is on advancing practical, low-carbon energy alternatives that promote energy independence and strengthen the economy. This segment is dedicated to the development, construction, and operation of Alcohol-to-Jet projects that are not only good for the environment but also cost-effective for businesses and consumers. Our flagship project, ATJ-30, is a groundbreaking greenfield initiative focused on producing SAF right here in the U.S.

GevoRNG segment. The Renewable Natural Gas segment includes GevoRNG which is an innovative project that leverages anaerobic digestion technology to capture and convert methane emissions into renewable natural gas. This project plays a significant role in addressing both the environmental impact of methane emissions and the growing demand for cleaner energy alternatives. RNG is chemically identical to conventional natural gas, but it is produced from organic waste rather than fossil fuels, making it a sustainable and carbon-neutral energy source. By converting methane emissions into RNG, Gevo RNG helps mitigate the environmental impact of livestock farming, specifically reducing the greenhouse gases that contribute to climate change.

​

GevoND segment. The GevoND segment is a new operating segment for 2025. The GevoND segment includes the assets acquired in the business combination completed in January 2025, with Red Trail Energy. GevoND includes advanced CCS technologies and low-carbon ethanol assets at the acquired facility in North Dakota, enhancing our portfolio of integrated, cost-effective carbon abatement solutions. The principal products manufactured by our ethanol plant include ethanol and distillers grains. At capacity, GevoND facility is capable of processing approximately 67 million gallons of low-carbon ethanol annually, including 2 million gallons of corn fiber ethanol with an ultra-low carbon intensity. Additionally, the facility produces more than 230,000 tons of low-carbon animal feed and vegetable oil, contributing to sustainable agriculture and food systems. The site has an operating, fully permitted Class VI CCS well, which captures and sequesters approximately 165,000 tons of biogenic carbon dioxide annually. This capability is a key component of our strategy to drive meaningful carbon abatement at scale, with the potential to sequester multiple times that amount in total carbon emissions, directly supporting Gevo’s vision of decarbonizing the energy, transportation, and agriculture sectors.

​

The "Other Expenses" in the segment table include the following components: cost of production, general and administrative expenses, acquisition-related costs, facility idling costs, gains and losses on the sale of assets and other expenses.
