Coskata’s platform technology is progressing to commercialization
Coskata has a 3-step process platform for biomass to fuels and chemicals
1. Biomass Gasification
2. Syngas Fermentation
3. Product Recovery
Can use any sustainable biomass
• First focus is Ethanol, but can selectively produce other fuels and chemicals
• Secured US Department of Agriculture’s intent to fund the largest biofuel loan guarantee in US Government history
Coskata’s ethanol technology is ready for commercialization and licensing
• Produces ~400 liters of ethanol per dry ton of material
• Feedstock flexible process enables rapid licensing and commercialization
3
Ethanol ProductionProprietary microorganisms convert syngas (CO and H2) into ethanol.
6 CO + 3 H2O C2H5OH + 4 CO2
6 H2 + 2 CO2 C2H5OH + 3 H2O
Each reaction is independent allowing for a range of H2/CO ratios.
Proprietary bioreactor designs enhance productivity.

Coskata Integrated Biorefinery Operating: Now ready for full-scale facilities
Coskata has: • Successfully scaled its
cellulosic ethanol technology
• Shown the process to be cost-competitive with gasolinefrom multiple feedstocks
• Completed design for commercial scale facilities
• Enabled commercialization through licensing model
IT’S TIME TO START BUILDING!

Ethanol-The Primary Renewable Liquid Fuel
•The biofuel option most naturally compatible with biomass will have the highest yield from the least amount of feedstock, leading to greater efficiency, lower costs, and less greenhouse gas emissions. •Because of its molecular advantages, biomass-to-ethanol achieves the highest yields.
•Requires at least half as much carbon as other biofuels,.•Makes the best use of the significant oxygen portion in the feedstock.

1) Biomass-to-ethanol has natural efficiencies. On a molecular level, ethanol is the fuel that is most compatible with biomass.
• Ethanol requires at least half as much carbon as other biofuels• Cellulosic ethanol is the fuel that best utilizes the oxygen in the biomass• A ton of biomass converted to ethanol will have higher yields than other alternative
biofuels, resulting in the lowest cost to the consumer, and less greenhouse gas emissions to the environment
2) Ethanol has a history of superior performance. A fabric of American transportation for over a century, ethanol has the proven longevity other fuels don’t.
3) Today’s cars are ready for ethanol. America’s cars are rapidly being developed to run on higher ethanol blends. The transition to electric vehicles will take decades. Ethanol is ready today.
4) Sufficient biomass exists to make an impact. America has sufficient biomass to supplant our dependence on foreign oil by 30%.
