Gevo, Inc.

Our corporate headquarters are part of our Gevo segment and are located in Englewood, Colorado, where we occupy office space used for executive management, finance, legal, commercial, and administrative functions. We also maintain laboratory, research, and technical facilities in Colorado to support our technology development and project engineering activities. Our corporate and laboratory facilities are leased under arrangements that we believe are adequate for our current needs. Our lease terminates in January 2029 and the leased space is approximately 19,241 square feet.

We own and operate the RNG plant in Iowa, which is included in our GevoRNG segment. This facility captures biogas from anaerobic digestion of agricultural feedstocks and upgrades the biogas to pipeline quality RNG. The property is leased and includes gas upgrading and conditioning equipment, interconnection assets, and related infrastructure necessary for RNG production and delivery. We have leased acreage at three dairy farms where the digesters are located. These leases expire at various dates between 2031 and 2050.

In addition, we own and operate an ethanol production facility located in North Dakota, which we acquired as part of our acquisition of the majority of the assets of Red Trail Energy and is included in our GevoND segment. The facility includes ethanol production, corn oil recovery, and related processing, storage, and handling infrastructure situated on owned land. The site also includes rail and logistics infrastructure supporting feedstock delivery and product shipment. Gevo North Dakota consists of an ethanol production plant with approximately 67 million gallons per year of capacity, a carbon capture and sequestration well injecting approximately 165,000 metric tons of CO₂ per year, and leases which give us rights to use additional pore space for carbon capture with an estimated capacity of one million metric tons per year.
