Slide 17

According to the EIA, there were 192 ethanol plants in the U.S. with aggregate annual capacity of approximately 17.4 BG as of January 2022 In the U.S., ethanol is primarily used as a gasoline blending component The U.S. fuel ethanol production market is fragmented, with the top five producers accounting for approximately 44% of total capacity through 69 plants Smaller producers compete on the strength of local supply and offtake markets and efficiency of operations – scale is not considered crucial to remaining competitive U.S. Ethanol Production Overview U.S. Ethanol Plant Map (192 plants) Source: EIA, Renewable Fuels Association EIA as of January 2022 U.S. Production Capacity by Producer1 (Billion Gallons per Year) Current Ethanol Market Overview U.S. Ethanol Plant Utilization POET Valero ADM Green Plains Andersons/Marathon All Others 12

High protein feeds are animal foods that contain approximately 30% to 60% protein, versus traditional animal feeds with less than 20% protein Traditional feeds, including distillers dried grains and soybean meal, were produced as by-products of corn and soy crushing to produce ethanol, soybean oil, vegetable oil and other traditional primary products Types of high protein feeds include fish meal, corn gluten meal and high protein soy meal Feeds with high protein concentrations sell at a premium given: Feeder / young livestock require a higher protein percent to properly develop and to develop more rapidly High protein contents decrease mortality rates of aquatic species High protein diets are growing in popularity for the domestic animal food industry The global animal feed protein market is estimated to be approximately $290 billion as of 2022 and is expected to surpass $420 billion by 2032, a 3.5% CAGR driven by rising demand for livestock feed and in the pet industry Current Ethanol Market Overview U.S. Feed Protein Market Overview Historical Average Protein Prices by Production Season ($ / ton) (% Protein Concentration) Source: USDA Note: (Percent) Represents average protein content Indexed High Protein Feed Consumption 5-Year Average Price ($ / ton) 13

Slide 50

Many analysts (Jefferies, Craig Hallum, Oppenheimer included) attributed the Q1 2023 miss to volatile ethanol markets, weaker crush margins, and increasing feedstock prices Analysts perceive GPRE as being on track with its transition to GPRE 2.0, as judged by key metrics such as rising run-rate Ultra-High Protein production, full production at existing 5 facilities, and heightened yields (on track for 4.0 lb UHP / bushel vs expected 3.5 lb) The biggest point of concern among research analysts is the projected UHP pricing premium, as, while still a significant value add (~$60 million EBITDA in 2022), it appears to be coming in below management’s expected J-Curve Research analysts project that beginning in 2025, GPRE’s partnership with Summit Carbon Solutions will contribute $50 – $100 million in EBITDA uplift due to a lower CI score with the possibility for further increases from IRA clarification Research analysts expect GPRE 2.0 to be rewarded by the diversity and transparency of its various business operations, and believe they are all viable opportunities to transition away from strict reliance on ethanol Wall Street Research Commentary Regarding Green Plains 2.0 Green Plains Inc. Situation Analysis Analyst Commentary While pointing to a more favorable ethanol crush margin backdrop, we reiterate our view that GPRE is on the precipice of delivering its biorefinery transformation vision. With our first look at UHP sales volumes, we are encouraged by production rates … Looking across each of its growth pillars (protein, oil, sugar, carbon), GPRE has multiple ways to win, however we see only one or two as needed to drive sustained positive EBITDA, and reduced earnings volatility. - Oppenheimer (May 2023) The company continues to make good progress on its 60% protein content product (for aquafeed), which comes with significantly higher premium. Sales towards that market could start in earnest by 4Q22 and grow from there. Additionally, we believe that pricing for recurring business is likely to increase as customers are satisfied with the results of their first order. - BofA Securities (May 2023) The good news is this [GPRE 2.0] plan continues to show tangible progress with full production of High Proteins reached at five plants with strong commercial demand, increased yields for renewable corn oil, Clean Sugars progressing towards the start-up of production at its Shenandoah, IA plant in early 2024, and the overall Carbon Capture opportunity becoming clearer. In addition, GPRE announced its offer to acquire Green Plains Partners (GPP) which would simplify its organization structure, reduce OpEx, and be accretive to cash flow. - Craig-Hallum (May 2023) Source: Wall Street Research 42
