Core offering

Southwest Iowa Renewable Energy (SIRE) operates a 110 million-gallon-per-year dry-mill ethanol production facility in Council Bluffs, Iowa, processing over 42 million bushels of corn annually into fuel-grade ethanol and animal feed co-products including dried distillers grains (DDG), wet distillers grains (WDG), corn syrup, and corn oil. The company operates on a farmer-owned cooperative model, with hundreds of local farmers holding ownership stakes and supplying corn to the facility.

Product overview

Southwest Iowa Renewable Energy (SIRE) operates a single ethanol production facility producing fuel-grade ethanol as its primary product. The company operates on a farmer-owned cooperative model, purchasing approximately 42 million bushels of corn annually to produce 110 million gallons of ethanol per year. The product portfolio centers on the core ethanol output supplemented by four distinct co-products: Dried Distillers Grains (DDG), Wet Distillers Grains (WDG), Corn Syrup, and Corn Oil—all derived from the corn processing and fermentation operations. Supporting the primary production are two customer-facing platforms: the Cash Bids Platform for grain purchasing operations and the My Grower Portal for account management. The Investor Portal serves shareholder communication needs. The company was incorporated in 2005, began production in 2009, and has invested over $60 million in grassroots capital from local farmer-owners.

• Pacific Ethanol: Pacific Ethanol operates dry-mill corn ethanol facilities producing fuel ethanol and co-products. As a multi-plant ethanol pure-play, it is closely comparable to SIRE's core business model.
• Valero Renewable Fuels: Valero operates ethanol plants as part of its broader refining footprint, producing fuel-grade corn ethanol and co-products. It competes with SIRE for ethanol offtake into fuel blending markets.
• Green Plains: Green Plains is a major U.S. dry-mill corn ethanol producer with multiple facilities producing ethanol, DDGS, and corn oil. SIRE's new CSO previously served as Head of Carbon at Green Plains, and the two companies compete directly for corn supply and ethanol customers in the Midwest.

Emerging players

• Gevo: Gevo is a renewable fuels company developing low-carbon ethanol and sustainable aviation fuel. It is an existing strategic partner of SIRE for low-carbon fuel development, making it both a collaborator and adjacent player in the low-carbon ethanol value chain.
• Aemetis: Aemetis operates corn ethanol and renewable diesel production with a strong focus on low-carbon fuel pathways and carbon intensity reduction. It is comparable to SIRE given its pursuit of low-carbon ethanol premiums and renewable fuel credits.

Broad incumbents

• Flint Hills Resources: Flint Hills Resources operates corn ethanol plants as part of its broader refining and chemicals portfolio. It is a Midwest-based ethanol competitor with comparable product offerings to SIRE.
• Archer Daniels Midland (ADM): ADM is a global agribusiness giant that operates corn dry-mill ethanol plants alongside its grain trading, oilseed processing, and animal nutrition businesses. ADM competes with SIRE in ethanol, DDGS, and corn oil markets while also being a major corn supplier.
