▌Investment Summary
REX American Resources (REX) looks like a good investment right now, earning an overall grade of B+ and a Buy. Our fair value estimate of $50 reflects strong liquidity, improving earnings, and project upside, while still accounting for cyclical ethanol spreads and 45Z dependence.

Thesis

REX American Resources (REX) offers a Buy opportunity for moderate-risk investors who can accept commodity-cycle volatility. The investment case rests on three concrete facts: fiscal 2026 revenue reached $650.5M, net income climbed to $83.0M, and free cash flow reached $49.4M; the company held $375.8M of cash and investments against $21.3M of total debt; and management is funding a One Earth ethanol expansion and carbon-capture project within a combined $220M to $230M budget.

The operating momentum is real but partly policy-assisted. Fiscal Q1 2026 gross profit rose to $29.1M from $14.3M, while REX recorded $7.5M of 45Z production tax credit income. Ethanol sales volume increased slightly to 71.1 million gallons from 70.9 million gallons, but the average ethanol selling price declined to $1.66 per gallon from $1.76. The earnings improvement therefore came from lower corn costs, tax credits, and stronger coproduct economics rather than from higher ethanol pricing alone.

REX's balance sheet gives the company room to invest through weak spreads, while the One Earth expansion provides a defined volume catalyst. The central risk is that ethanol remains a commodity business exposed to corn, fuel, coproduct, natural gas, trade, and regulatory prices. The report's fair value estimate of $50 reflects strong liquidity, improving earnings, and project upside, discounted by cyclical earnings and dependence on 45Z economics.

Company Overview

REX American Resources is a Dayton, Ohio-based ethanol producer and investor founded in 1980. The company has 132 employees and trades on the NYSE under the symbol REX. Its operations center on fuel ethanol and related products, including distillers grains, distillers corn oil, corn, gasoline, and natural gas.

REX reports one operating segment covering ethanol and by-products. The company has interests in six facilities across four Midwest states, with approximately 730 million gallons of total production capacity and roughly 300 million gallons of annual ownership-controlled volume. REX owns 99.7% of NuGen Energy in Marion, South Dakota, 76.1% of One Earth Energy in Gibson City, Illinois, and minority positions in four Big River facilities.

▌Common Questions

Frequently asked questions

+Is REX stock a buy right now?
Yes, REX looks like a Buy for investors who can tolerate commodity-cycle volatility. The report gives it an overall grade of B+ because liquidity is strong, earnings are improving, and the One Earth expansion plus carbon-capture project could add meaningful upside.
+What is REX's fair value?
REX's fair value is $50. That view reflects strong liquidity, fiscal 2026 net income of $83.0M, and the growth potential from the One Earth expansion and carbon-capture project, while still discounting the cyclicality of ethanol spreads and reliance on 45Z economics.

Business Segment Deep Dive

The consolidated business is built around two majority-owned plants, while the Big River investments add exposure to a wider operating network without requiring full ownership of every facility. NuGen has approximately 150 million gallons of annual capacity. One Earth also has approximately 150 million gallons of capacity and is being expanded first to 175 million gallons, with a longer-term path toward 200 million gallons.

The product mix shows why REX is more than a single-output ethanol producer. In fiscal Q1 2026, the company sold approximately 155,000 tons of dry distillers grains at an average price of $155.86 per ton, 13,400 tons of modified distillers grains at $76.94 per ton, and 23.9 million pounds of corn oil at $0.54 per pound. These coproducts create additional revenue streams from the same corn grind.

Annual results show a business with strong earnings leverage. Revenue was $855.0M in fiscal 2023, fell to $642.5M in fiscal 2025, and recovered to $650.5M in fiscal 2026. Net income moved from $27.7M to $58.2M and then $83.0M over the same periods. That pattern captures the appeal and the danger: modest revenue changes can produce large swings in profit when ethanol spreads and coproduct prices move favorably.

Flagship Product Analysis

Fuel ethanol is REX's flagship product and the main driver of plant utilization. Fiscal Q1 2026 ethanol volume reached 71.1 million gallons, up from 70.9 million gallons a year earlier. The average selling price fell to $1.66 per gallon, which reduced revenue quality even as lower corn pricing and tax credits lifted gross profit.

The coproduct portfolio improved during the quarter. Dry distillers grain pricing increased from $145.65 to $155.86 per ton, while corn oil pricing rose from $0.46 to $0.54 per pound. Those gains helped offset the lower ethanol price and demonstrate the value of extracting more commercial value from each bushel of corn.

Ethanol demand also benefits from blending requirements and expanding E15 access. EPA actions described in the industry data support nationwide year-round E15 sales and permit gasoline blends containing 9% to 15% ethanol under a common volatility standard. That policy expands the practical market for ethanol, although the realized benefit still depends on plant margins and industry supply.

Innovation & Competitive Advantage

REX's competitive advantage is operational rather than technological in the traditional software sense. Midwest locations support corn sourcing and logistics, while distillers grains and corn oil improve revenue per bushel. The company also uses forward purchase and sale contracts and exchange-traded futures to manage part of its commodity exposure.

Carbon capture is the most important strategic innovation. REX's planned project near One Earth is designed to capture approximately 560,000 tons of carbon annually after expansion, with three injection wells and stated underground storage capacity of 90 million tons. The project could improve the carbon intensity of REX's ethanol and support 45Q and 45Z economics.

The project is also the clearest execution risk. REX had invested approximately $176M in the expansion and carbon-capture initiatives by the end of fiscal Q1 2026, against a combined budget of $220M to $230M. The return profile depends on permitting, construction, tax-credit rules, and the company's ability to monetize lower-carbon ethanol.

Operations & Supply Chain

REX's supply chain begins with corn and natural gas and ends with ethanol, distillers grains, corn oil, and carbon-related products. As of January 31, 2026, the company had purchase commitments for approximately 18.4 million bushels of corn and 1.7 million MMBtu of natural gas. It also had sales commitments for approximately 54.8 million gallons of ethanol, 107,000 tons of distillers grains, and 17.0 million pounds of distillers corn oil.

The 10-K reported approximately $123.0M of contracted future payments for corn, natural gas, a natural gas pipeline lease, and capital expenditures, with $108.3M payable within twelve months. That commitment profile is manageable relative to REX's cash resources, but it means the company remains exposed to input costs even when product prices weaken.

One Earth expansion work was progressing on schedule, with management targeting completion by the end of calendar 2026 and full operation during fiscal 2026. The Illinois carbon-pipeline moratorium was scheduled to expire on July 1, 2026, creating a defined regulatory milestone for the sequestration project. Capital spending has already reduced cash from $375.8M at fiscal year-end to $364.3M in cash, equivalents, and short-term investments at April 30, 2026.

Market Analysis

The relevant market for REX is U.S. fuel ethanol rather than conventional petroleum refining. The Renewable Fuels Association reported record U.S. ethanol production of 16.49 billion gallons in 2025, while REX's investor materials place its total facility capacity at approximately 730 million gallons annually. The industry's scale provides liquidity and demand, but it also attracts large producers with substantial capital.

Export momentum has been constructive. Management cited a 20% increase in 2026 ethanol exports through March compared with the same period a year earlier. Domestic demand was described as stable, and EPA policy supporting year-round E15 improves the industry's blending opportunity.

The longer-term market is mature rather than a pure secular-growth story. A market estimate places global fuel ethanol at $118.8B in 2026 and $144.3B by 2030, with North America holding 56.4% of the market in 2023. For REX, the practical growth levers are higher owned capacity, stronger coproduct pricing, export demand, and lower-carbon fuel credits.

Customer Profile

REX sells ethanol into fuel markets, where customers include fuel blenders and distributors serving motorists. The company's ethanol volume of 71.1 million gallons in fiscal Q1 2026 shows the scale of the core customer channel. E15 policy directly affects the volume opportunity available to those buyers.

Coproduct customers are more diversified. Dry distillers grains are used as a protein source in animal feed, while corn oil serves feed, industrial, and renewable-fuel markets. Fiscal Q1 sales of 155,000 tons of dry distillers grains and 23.9 million pounds of corn oil show that coproduct demand is a meaningful part of the commercial model.

Competitive Landscape

REX competes with POET, Valero Renewable Fuels, Archer-Daniels-Midland (ADM), Green Plains, other U.S. ethanol producers, and foreign suppliers such as Brazil-based producers. The company's 10-K identifies larger companies with greater financial resources as a competitive pressure.

REX's scale is smaller than the largest industry platforms, but its ownership model provides concentrated exposure to two majority-owned plants and minority exposure to four Big River facilities. The combination of Midwest locations, direct farmer corn sourcing, coproduct marketing, and operating oversight forms a practical advantage rather than a durable structural moat.

The competitive test is plant economics. Larger rivals can spread corporate costs across more gallons and fund projects from broader businesses. REX counters with low leverage, $354.5M of net cash, and a history of profitability. Its earnings history records a 5-for-6 beat rate across the available comparable quarters, although one missed quarter shows that operating execution is not automatic.

Macro & Geopolitical Landscape

Policy is a direct earnings input for REX. The company began recognizing 45Z production tax credits in the fourth quarter of 2025 and recorded $7.5M during fiscal Q1 2026 at $0.10 per gallon for consolidated plants. Federal discussions around 45Z rules and state-level permitting for the Illinois carbon pipeline therefore have direct economic importance.

Trade policy adds a second external variable. REX's risk disclosures identify foreign ethanol competition, U.S. foreign trade policy, and tariffs as factors that can affect results. The cited 20% increase in ethanol exports through March supports demand, but export growth also leaves the company exposed to trade restrictions and overseas pricing.

Commodity sensitivity remains the central macro risk. REX's January 31, 2026 risk analysis estimated pre-tax income reductions of $48.9M from a 10% adverse change in ethanol prices and $41.2M from a 10% adverse change in corn prices. The same analysis estimated impacts of $8.5M for distillers grains, $4.4M for distillers corn oil, and $2.2M for natural gas.

Seasonality also matters. REX's 10-K states that ethanol demand generally increases during spring and summer months and holiday travel. That pattern aligns with the company's focus on summer blending demand, but it does not remove the effect of corn and ethanol spread volatility.

Closing

REX has the financial foundation many small commodity producers lack. Fiscal 2026 ended with $610.7M of equity, $375.8M of cash and investments, only $21.3M of total debt, and $49.4M of annual free cash flow. The company also delivered its 20th consecutive profitable quarter and recorded fiscal Q1 EPS of $0.56.

The investment case is strongest when REX is treated as a disciplined ethanol operator with optionality, rather than as a high-growth industrial company. One Earth expansion, coproduct pricing, exports, and carbon capture create identifiable upside levers. Corn and ethanol prices, tax-credit policy, trade exposure, and project permitting create equally identifiable risks. At a $50 fair value estimate, the appropriate stance is Buy for patient investors who can tolerate earnings volatility and Hold for investors already positioned near that level.

Why did REX's earnings improve so much?
REX's fiscal Q1 2026 gross profit rose to $29.1M from $14.3M because lower corn costs, stronger coproduct economics, and $7.5M of 45Z production tax credit income boosted margins. Ethanol volume only edged up to 71.1 million gallons, so the profit jump was driven more by pricing and policy support than by higher sales volume.
+How strong is REX's balance sheet?
REX has a very strong balance sheet, with $375.8M of cash and investments versus just $21.3M of total debt. That gives the company room to keep funding the One Earth expansion and carbon-capture buildout even if ethanol margins soften.
+What is the main risk for REX investors?
The main risk is that REX remains a commodity business exposed to corn, fuel, coproduct, natural gas, trade, and regulatory prices. The stock's upside depends on maintaining favorable spreads and on successful permitting and monetization of the carbon-capture project.
