Current report

In the United States, we believe that the most practical economical feedstock to make jet fuel and other hydrocarbons are plant sugars from non-food corn. During processing, the corn kernels’ sugars (carbohydrates) are converted into ethanol, and the resulting protein and oil fractions are captured and marketed as valuable co-products. The ethanol can then be converted into jet fuel through a series of catalytic chemical process steps. For its initial series of ATJ plants, Gevo uses commercially proven process steps, and optimizes them into an overall design that creates high selectivity of products, and minimizes energy use in the integrated plant. The jet fuel and diesel products are drop-in fuels that meet standard specifications. In addition to meeting standard fuels specifications, production of the fuels also create the attributes of carbon removal and carbon abatement. In other words, it is possible through Gevo process designs, carbon sequestration, and energy sourcing to produce jet fuel that can achieve a zero or even negative footprint across the whole life cycle. Market demand for jet fuel continues to increase, and the Company’s technologies are designed to produce economical, sustainable fuel that may help address this demand. In addition, global interest in carbon abatement and removal is growing, and the Company’s processes are designed to enable participation in this evolving market.

In order to achieve full construction financing for an ATJ plant, we need to secure debt and possibly third-party equity. On October 16, 2024, we received a conditional commitment from the U.S. Department of Energy (“DOE”) Loan Programs Office (“LPO”) for a loan guarantee facility with a capacity of approximately $1.6 billion (including capitalized interest during construction). This milestone was significant as it helped to validate ATJ plant design integrity, which is underpinned by the DOE LPO’s diligence process. On October 8, 2025, the company received a letter from the DOE LPO granting an extension of the Conditional Commitment until April 16, 2026 (the “Extension”). The Extension allows the Company and DOE LPO to evaluate certain potential modifications to the project scope under the conditional commitment in order to address energy policies and priorities. The Conditional Commitment will remain effective during the extension period in order to allow for modifications which satisfy DOE LPO. The potential scope modifications include the construction of a lower cost ATJ-30 facility at GevoND and the optimal use of captured carbon dioxide for enhanced oil recovery.

Commodity Insights projects that global jet fuel production is expected to peak around 2035 at 7.8 million barrels per day, with SAF comprising approximately 11% of the aviation fuel mix. By 2050, the contribution of SAF could increase significantly, potentially representing 36% of global aviation fuel consumption, according to Commodity Insights. The International Air Transport Association (“IATA”), which represents over 300 airlines worldwide, forecasts that air travel demand will continue to grow, with the potential to double by 2040 compared to 2019 levels. In support of this growth, the IATA has adopted a resolution urging its members to achieve net-zero emissions by 2050. In line with this, the Boston Consulting Group anticipates substantial growth in global SAF demand in the coming decades, with SAF expected to account for 12% of global aviation energy demand by 2050.

We first designed the business system based on the ATJ-60 size. We identified a site in Lake Preston, South Dakota which we own, to deploy the ATJ-60 system. We then duplicated and modified the ATJ-60 designs to design the ATJ-30 business system. We believe GevoND would be an excellent site to deploy ATJ-30. We have also been in discussions with other companies around the world to deploy our SAF business systems.

Previous report

In order to achieve full construction financing for ATJ-60, we need to secure third-party equity and debt. On October 16th, 2024, ATJ-60 reached a critical milestone of receiving conditional commitment from the DOE for a loan guarantee facility with a capacity of approximately $1.6 billion (including capitalized interest during construction). This milestone is significant as it helps to validate ATJ-60’s integrity, which is underpinned by the DOE’s diligence process. The focus is now on negotiating and closing this DOE loan and our project level equity financing as quickly as possible. We expect that our ATJ-60 plant start-up date will occur approximately thirty-six months after the ATJ-60 financing closes, the timing of which is uncertain. We are also working to secure access to carbon capture and sequestration at the site.

Our primary market focus, given the large demand and growing customer interest, is carbon abated hydrocarbon fuels, including SAF. We believe that SAF produced from a carbohydrate-to-alcohol process is the most economically viable approach to meet growing jet fuel demand and to generate value from carbon abatement. We also have commercial opportunities for other renewable hydrocarbon products, such as RNG; hydrocarbons for gasoline and racing fuel blendstocks and diesel fuel; ingredients for the chemical industry, such as ethylene and butenes for plastics and materials; and other chemicals. With the recent acquisition of the majority of the assets of Red Trail Energy, which specialized in the production of ethanol and feed co-products from corn and sequestering carbon through its carbon capture and sequestration asset, we have expanded our capabilities in the biofuels and carbon marketing sector. Red Trail Energy’s operations complement our renewable fuels strategy and enhance our ability to provide sustainable fuel alternatives and carbon sequestration, supporting our broader goal of diversifying renewable product streams.

Previous wording

To serve these markets, we are developing commercial projects for converting renewable energy into energy-dense, liquid hydrocarbons that can be used as renewable fuels, such as SAF, with the potential to achieve a cost competitive jet fuel with reduced or eliminated greenhouse gas (“GHG”) footprint. We believe that this addresses the global need of economically reducing GHG emissions with “drop in” synthetic petroleum fuels. We use the Argonne National Laboratory’s Greenhouse gases, Regulated Emissions, and Energy use in Transportation model (the “GREET Model”) to measure, predict and verify GHG emissions across the life cycle of our products. Gevo expects that by using sustainably grown feedstock (e.g., low till, no-till cultivation, ethanol and other alcohols) and renewable and substantially decarbonized energy sources, drop-in hydrocarbon fuels can be produced that have a reduced or eliminated full life cycle footprint measured from the capture of renewable carbon through the burning of the fuel. This is because such feedstocks come from crops, which take carbon dioxide out of the atmosphere and convert it into biomass through photosynthesis. This yields vital amino acid nutrients, or protein, that humans and animals can consume, as well as vegetable oil and carbohydrates, or sugar. The plant sugar may be fermented with microorganisms to produce a clean alcohol suitable for on-road fuels, or for further industrial scale chemical processing into hydrocarbons. Given the overabundance of plant-derived sugar, the growing unmet demand for drop-in, renewable hydrocarbons such as SAF, and the availability of demonstrated industrial-scale technologies that can convert plant sugars to alcohols and then to hydrocarbons, we view our projects as first movers in an attractive, scalable new industry connecting this overabundance of plant sugar to unmet demand for products such as low-carbon ethanol, nutrients and SAF.

GevoND. On September 10, 2024, Gevo and its subsidiaries entered into an Asset Purchase Agreement with Red Trail Energy to acquire substantially all of its assets and assume certain liabilities. The acquisition was completed on January 31, 2025, for a purchase price of $210 million, subject to customary adjustments, including a working capital adjustment. The transaction was funded through a combination of Gevo equity capital, and a $105 million senior secured term loan facility and $5 million in equity from Orion Infrastructure Capital (“OIC”), a U.S.-based private investment firm. OIC’s equity contribution resulted in the creation of a redeemable non-controlling interest (“NCI”). This NCI is subject to a Put/Call option feature, which grants Gevo the right to call (purchase) the units held by OIC, and OIC the right to put (sell) the units to Gevo under certain conditions. These options are exercisable for a period of three years following the repayment of all outstanding debt under the credit agreement with OIC. As a result of the redeemable nature of this non-controlling interest, it has been classified as temporary equity on the Company’s Condensed Consolidated Balance Sheets.

The acquired assets include an ethanol production plant, a carbon capture and storage well, and leases which give us rights to use additional pore space for carbon capture. The operational personnel of Red Trail Energy joined Gevo upon the closing of the acquisition. The acquired ethanol production facility converts corn into ethanol and distillers grains, a high-protein animal feed containing essential amino acid nutrients, and corn oil. The included carbon capture and sequestration (“CCS”) assets are expected to support Gevo’s broader carbon abatement goals, particularly in relation to its Renewable Jet Fuel Platform. We believe the acquisition strengthens Gevo’s growth trajectory by adding ethanol production, distillers grains, corn oil, and CDR credit sales to our revenue stream, while also enhancing our capabilities in CCS and supporting our broader strategic efforts in SAF production which use low-carbon alcohol as a feedstock.

ATJ-30 at GevoND. We have duplicated and modified the ATJ-60 design into an ATJ-30 design which we expect will be deployed for our North Dakota site, which would upgrade the low-carbon ethanol already produced onsite to jet fuel. We expect to continue engineering and development through 2025 and into 2026 before completing the front-end engineering design (“FEED”) phase of the project. At the end of FEED, we expect to have a capital estimate and schedule for the project. Because we began with the designs and know-how from the ATJ-60 project, we are able to shorten the time and costs to complete the development phase of the project.

ATJ-60 at Lake Preston, South Dakota. ATJ-60 is designed to produce approximately 65 MMGPY of total hydrocarbon volumes, including 60 MMGPY of SAF. The liquid hydrocarbons, when burned, are expected to have a “net zero” GHG footprint. Along with the hydrocarbons, ATJ-60 is expected to produce approximately 1.3 billion pounds per year of high-value protein products for use in the food chain and approximately 30 million pounds per year of corn oil. Our products will be produced in three steps: the first step is milling the corn to produce the carbohydrates needed for the production of SAF while simultaneously enabling the production of protein and oil; the second step produces alcohols using carbohydrate-based fermentation; and the third step is the conversion of the alcohols into hydrocarbons. In connection with the planned construction of Gevo’s ATJ-60 SAF facility, Gevo commissioned an analysis by Charles River Associates, which estimated that the facility will contribute approximately $116 million annually to the local economy, generating 100 direct jobs at the plant and creating an additional 736 local jobs. Furthermore, the analysis estimated that (i) the construction phase of the ATJ-60 facility is projected to provide a temporary $184 million economic boost and support 1,266 jobs; and (ii) the facility is expected to generate $1.82 per gallon of SAF produced in local economic value and contribute an estimated $23 million annually in federal tax revenue.

However, given the uncertainty associated with the Summit Carbon Solutions pipeline for carbon sequestration, this project is currently on hold.

Previous wording

We currently expect to finance the construction of ATJ-60 at the subsidiary level using a combination of Company equity (including funds already spent on the project), and capital from project level equity and debt financing. The Company previously projected $40.0 million would be spent on ATJ-60 between January 2025 and the financial close of ATJ-60. The Company expects that the timing of this remaining spending will align with the timeline for financial close of the project. Cash distributions from future ATJ-60 earnings would be proportionate to Gevo’s ownership in ATJ-60 under this expected financing structure. The use of project debt and third-party equity allows us to conserve capital for use on other growth projects. We expect to apply similar development and financing strategies to future Alcohol-to-Jet Projects to grow our SAF production to meet the demand for SAF.

Ethanol to Olefins and the Axens Agreement. Axens and Gevo are building on their previous successful commercial cooperation to ensure they remain leaders in the ETJ space by partnering with IFPEN on the final development and commercial deployment of Gevo’s next-generation ETO process for fuel applications that are expected to achieve zero carbon intensity or better. Gevo’s ETO process produces light olefins from ethanol, which can then be converted to transportation fuels utilizing commercially proven oligomerization and hydrogenation technologies. Provided the technology development is completed successfully, Gevo is expected to lead deployment of its ETO technology in North America with an effort to bring high-quality jobs and economic development to rural America, and Axens would provide process licensing, catalyst, equipment, and engineering services globally.

Luverne Facility.** **On May 28, 2025, Gevo entered into a definitive agreement to sell Agri-Energy, LLC (“Agri”), a wholly owned subsidiary of Gevo, to A.E. Innovation, LLC (“A.E.”) for $7 million. The transaction includes the Luverne Facility and is expected to close by the end of 2025, subject to the procurement of financing by A.E. and the satisfaction of other customary closing conditions. Gevo will retain ownership of certain isobutanol-production-related assets and a portion of the vacant land at the site for future use. With these retained assets, Gevo could potentially produce up to 1 million gallons per year of isobutanol, which can be sold as a specialty chemical or converted into isooctane and jet fuel. A.E., an agriculture-oriented buyer group located in Minnesota, will acquire the ethanol plant and a portion of the land with the intent to restart ethanol production, which has been idled since 2022 as we shifted focus to our Renewable Jet Fuel Platform. Over the last several years, the Luverne Facility, in conjunction with local farmers, has been used as a demonstration site for educating Gevo’s stakeholders about regenerative agriculture and the versatility of corn and its co-products, as well as biofuel production, including SAF, isobutanol, and ethanol.
