11 CO2 is a Co - Product We Can Monetize in Multiple Ways (1) LCFS prices based on recent ranges of British Columbia, Alberta, Oregon Washington and California. CDR prices based on a ver age prices listed on https://www.cdr.fyi/ using Bioenergy with Carbon Capture and Sequestration credits (illustrative range shown with $200 per metric ton, the reported aver age price, as the midpoint). Carbon Dioxide Removal (CDR) Markets Low Carbon Fuel Standard (LCFS) Markets Biofuels sold in non - LCFS markets; CDRs can be detached and sold on a global marketplace without double counting Biofuels can be transported to these end markets with the CCS value attached How it works Examples Canada (national Clean Fuel Reg), British Columbia, Washington, Oregon and California + other potential states End Users $100 – 300 per metric ton Enhances our optionality and our revenue stability $50 – 200 per metric ton Illustrative Prices There are two primary end markets to monetize our carbon value. By optimizing the mix, we can maximize value and serve the greatest demand.

12 Large Potential Adjusted EBITDA Growth (Prior to deploying ATJ plants) (1) Adjusted EBITDA potential is based on information currently available to the Company and based on certain assumptions made by th e Company. Such figures are estimated consistent with relevant past practice. Adjusted EBITDA is a non - GAAP measure calculated by adding back depreciation and amortization, allocated intercompany expenses f or shared service functions, non - cash stock - based compensation, and the change in fair value of derivative instruments to GAAP income (loss) from operations as well as monetized tax credits, if any . W e are unable to provide a reconciliation of adjusted EBITDA potential to the most comparable GAAP measure without unreasonable effort because estimating such GAAP measures and providing a meaningful reconcil iat ion is extremely difficult and requires a level of precision that is unavailable for these future periods, and the information needed to reconcile these measures is dependent upon future events, many of whi ch are outside of our control. (2) A reconciliation of adjusted EBITDA to GAAP income (loss) from operations for the three and six months ended June 30, 2025 is pr ovided in the Appendix. • Potential from Carbon Value by optimizing current production based on existing 165,000 mt of carbon captured currently. But potential is to capture 1 million tons per year by generating more CO 2 on site or by bringing third party volumes to the site. • Plan to sell to a mix of Voluntary Carbon Dioxide Removals Credits (CDRs) or using the carbon value in regulatory markets if that value is greater. • Potential to debottleneck and grow current production of ethanol and corresponding CO 2 production Adjusted EBITDA Potential from optimizing current production (1) ($ in millions, annualized) ($45) Adjusted EBITDA Potential from expanding current production, before deploying ATJ plants (1) ($ in millions, annualized) As of 2Q25, we achieved a run rate adjusted EBITDA of $20 million.

Why We Like SAF (Jet Fuel) and Especially ATJ 14

15 Jet Fuel Demand is Increasing, Gasoline Decreasing US Jet Fuel Demand US Gasoline Demand Compare to: The Alcohol - to - Jet process targets +90% jet fuel yield in its product stream

Cost Effective: Alcohol - to - Jet is the Most Competitive Cash Cost of Production to make SAF Cash cost of production represents total economic cost of production before capital cost. Does not include federal and state in centives. Based on work done by an independent global consulting firm, Nexant , Cancawe - Aramco, and Gevo analysis. SAF production cash cost shown before Federal and state incentives such as RINs, LCFS, 45Z and other state SAF tax credits, and before new capital cost. AtJ SAF cost assumes approximately $5.00/ bu corn for illustrative purposes; estimates dependent on feedstock prices and other assumptions. SAF Cash Cost of Production vs. Fossil Jet Fuel Price ATJ SAF cash cost of production is expected to be competitive with fossil jet fuel prices, even though ATJ SAF can deliver 100% or more carbon abatement per gallon Gevo’s proprietary integrated process design and technologies lead to most favored competitive position We use proven and fully scaled up unit operations The future of aviation is Alcohol - to - Jet ; it’s the most competitive on a cash cost of production basis Three plant de signs a vailable : 30 MGPY, 60 MGPY , and 150 MGPY SAF Fossil Jet Fuel Gevo ATJ Project 16 HEFA

30 MGPY ATJ Production Expected to Add Significant Value to Ethanol Sites Adjusted EBITDA potential is based on information currently available to the Company and based on certain assumptions made by th e Company. Such figures are estimated consistent with relevant past practice. Adjusted EBITDA is a non - GAAP measure calculated by adding back depreciation and amortization, allocated intercompany expenses f or shared service functions, non - cash stock - based compensation, and the change in fair value of derivative instruments to GAAP income (loss) from operations as well as monetized tax credits, if any. We ar e u nable to provide a reconciliation of adjusted EBITDA potential to the most comparable GAAP measure without unreasonable effort because estimating such GAAP measures and providing a meaningful reconciliation is e xtr emely difficult and requires a level of precision that is unavailable for these future periods, and the information needed to reconcile these measures is dependent upon future events, many of which are outside of ou r control. • Must use the low cost (Gevo) production technology and plant design • Additional carbon abatement of +300,000 tons can be generated by manufacturing jet fuel with a zero CI • Carbon value must be captured through voluntary and regulatory markets • Co - product value must be captured • Increase use of CCUS • Maximize production volumes 17 Pre - ATJ Net Adjusted EBITDA Total (+) (+) ~$150M/y ATJ Adjusted EBITDA Contribution • 50MGPY of Ethanol produces 30MGPY of jet fuel • 30MGPY of production is “minimum” economic size to achieve economies of scale • 60 MGPY would require 100MGPY of ethanol and generate about 2x the Adjusted EBITDA (little economies of scale) $X

18 Ethanol Infrastructure Can Be Leveraged for ATJ Platform • 0.15 million barrels per day, or 2.3 billion gallons per year, of new jet fuel demand by 2035 • Requires +70 Alcohol - to - Jet facilities, each producing 30 million gallons of jet fuel per year • Would consume 3.5 billion gallons of ethanol from plant starch – a renewable domestic resource US Ethanol Facilities Map (~180 in operation) +70 Alcohol - to - Jet Facilities Needed to Meet Jet Fuel Demand For Each Site: • +$100M/y EBITDA • +$70M/y regional impact • +400 - 600 jobs, direct and indirect • More uses for US corn
