Growing EV Use Will Undermine Corn Ethanol Demand

Key Takeaways

• Shifts toward electric vehicles and policy focus on environmental impacts threaten long-term demand and pricing power for corn-based ethanol.
  
• Volatile commodity markets, high capital spending, and competition from advanced biofuels undermine margin stability and future growth prospects.
  
• Policy-driven incentives, efficiency gains, and new carbon and export revenue streams are strengthening Green Plains' earnings stability and growth prospects while lowering reliance on volatile ethanol margins.

Catalysts

Produces low-carbon fuels in the United States and internationally.

• The acceleration of electric vehicle adoption globally, combined with increasing regulatory scrutiny that may shift future incentives toward non-crop-based renewables and electrification, presents a significant risk of eroding demand for ethanol, undermining core revenue generation for Green Plains over the next decade.
  
• Policy risk remains elevated despite recent favorable U.S. legislation; future government and investor focus on the environmental impact of land and water usage could result in new restrictions or negative perception of corn-based ethanol, curtailing volumes and putting long-term pricing power and net margins under pressure.
  
• Green Plains continues to rely heavily on volatile commodity markets for both corn inputs and ethanol output, leading to persistent unpredictability in margins and earnings regardless of recent operational improvements, thereby threatening the sustainability of cost reductions and cash flow stability.
  
• Heavy ongoing capital expenditures for carbon capture projects and biorefinery transformation, combined with potential misexecution or policy reversals, risk producing lower than projected returns on investment and lower free cash flow, extending Green Plains' recent history of net losses.
  
• Advancements in alternative biofuels such as renewable diesel and sustainable aviation fuel, along with tightening emissions standards and unpredictable agricultural commodity prices driven by climate or supply shocks, threaten to outcompete traditional ethanol and compress Green Plains' addressable market, putting future revenue growth and EBITDA expansion at risk.

Green Plains Future Earnings and Revenue Growth

Assumptions

How have these above catalysts been quantified?

• This narrative explores a more pessimistic perspective on Green Plains compared to the consensus, based on a Fair Value that aligns with the bearish cohort of analysts.
• The bearish analysts are assuming Green Plains's revenue will grow by 21.4% annually over the next 3 years.
• The bearish analysts assume that profit margins will increase from -5.8% today to 4.7% in 3 years time.
• The bearish analysts expect earnings to reach $176.3 million (and earnings per share of $3.25) by about May 2029, up from -$121.3 million today. The analysts are largely in agreement about this estimate.
• In order for the above numbers to justify the price target of the more bearish analyst cohort, the company would need to trade at a PE ratio of 5.9x on those 2029 earnings, up from -10.3x today. This future PE is lower than the current PE for the US Oil and Gas industry at 14.6x.
• The bearish analysts expect the number of shares outstanding to grow by 6.79% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 6.98%, as per the Simply Wall St company report.

Risks

• U.S. government policy support has strengthened notably with the recent extension of the 45Z clean fuel production tax credit through 2029, removal of the indirect land use change penalty, and full credit transferability, which is projected to deliver over $150 million in annual EBITDA from just three Nebraska plants starting in 2026, and such policy-driven revenue can significantly boost earnings and free cash flow.
  
• Green Plains has delivered on cost reduction and operational efficiency initiatives, already surpassing a $50 million savings target and maintaining over 99% capacity utilization at its plants, which supports higher net margins and improved earnings stability even in a volatile commodity environment.
  
• Monetization of carbon capture and sequestration (CCS) assets is on track and expected to generate material predictable cash flows for the company due to regulatory clarity and demand for low-carbon fuels, supporting a transformation in long-term earnings power and reducing dependency on ethanol price cycles.
  
• Continuous improvement in corn oil yields and value capture is reinforced by sustained demand from renewable diesel producers and favorable regulatory changes, promising higher incremental revenue streams and margin uplift even as protein values fluctuate.
  
• Growing ethanol exports, along with access to new markets through strategic marketing and supply chain partnerships, are likely to expand Green Plains' addressable market and contribute to top-line revenue growth, particularly as global biofuel blending mandates strengthen and U.S. energy trade policy remains favorable.

Valuation

How have all the factors above been brought together to estimate a fair value?

• The assumed bearish price target for Green Plains is $10.0, which represents up to two standard deviations below the consensus price target of $15.38. This valuation is based on what can be assumed as the expectations of Green Plains's future earnings growth, profit margins and other risk factors from analysts on the more bearish end of the spectrum.
• However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of $19.0, and the most bearish reporting a price target of just $10.0.
• In order for you to agree with the more bearish analyst cohort, you'd need to believe that by 2029, revenues will be $3.7 billion, earnings will come to $176.3 million, and it would be trading on a PE ratio of 5.9x, assuming you use a discount rate of 7.0%.
• Given the current share price of $17.76, the analyst price target of $10.0 is 77.6% lower. Despite analysts expecting the underlying business to improve, they seem to believe the market's expectations are too high.
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
