What REX American Resources Corp. told the SEC could break it.
REX American Resources' disclosures are dominated by the economics of corn ethanol. Corn was about 74% ($411.5 million) of cost of sales in fiscal 2025, and its single-feedstock plants in corn-growing regions have limited alternatives, so its margins ride on the crush spread — a 10% adverse move in corn prices would cut pre-tax income by roughly $41 million. Virtually all its ethanol is sold with RINs that customers use to meet the Renewable Fuel Standard, making EPA decisions on Small Refinery Exemptions and RFS rulemaking central to RIN values and demand. And with a large share of distillers grains exported, trade restrictions or new tariffs — particularly from Canada and Mexico — could make those exports uneconomical and depress prices.

In its own words
What could break it.
Regulatory & policy
- RFS / RIN / EPA Small Refinery Exemption (SRE) policyhigh
Virtually all of REX's ethanol is sold with RINs used by customers to comply with the Renewable Fuel Standard (RFS II); EPA decisions on Small Refinery Exemptions and RFS rulemaking (e.g., the 2025 SRE rulings and 37 pending petitions) drive RIN values and renewable-fuel blending demand, directly affecting REX's economics.
“Virtually all our ethanol is sold with RINs that are used by customers to comply with RFS II. If our production does not meet EPA requirements for RIN generation, as an efficient producer, in the future, we would have to purchase RINs in the open market or sell our ethanol at substantially lower prices, such as on the export market, to adjust for the absence of RINs.”
SEC filing →As of 2026 - Export tariffs/trade restrictions on ethanol and distillers grains (Mexico/Canada)medium
About 36% of U.S. distillers grains were exported in 2025 (20% to Mexico); trade restrictions or additional duties/tariffs on U.S. exports — particularly by Canada and Mexico — could make ethanol and distillers-grains exports uneconomical and depress prices.
“If producers and exporters of ethanol and distillers grains are subjected to trade restrictions, or additional duties or tariffs are imposed on U.S. exports, particularly by Canada and Mexico, it may make it uneconomical to export these products.”
Commodity & input dependence
- Corn = ~74% of cost of sales; single-feedstock plantshigh
Corn accounted for ~74% ($411.5M) of cost of sales in fiscal 2025 and natural gas ~5%; REX's plants are single-feedstock corn facilities in corn-growing areas with limited alternative feedstock, leaving margins exposed to the crush spread (a 10% adverse corn price move would cut pre-tax income by ~$41M).
“Corn accounted for approximately 74% ($411.5 million) of our cost of sales during fiscal year 2025 compared to approximately 76% ($416.4 million) during fiscal year 2024.”
