• Leveraging CropOS^® Technology Platform: Benson Hill's unique and proprietary innovation engine, CropOS^®, combines data science, plant science and food science to create innovative food and ingredient products. The Company has a robust proprietary data library that is expected to double in size every year, with high-performance soybean breeding data, hundreds of billions of data points to understand natural genetic variation for biodiversity, and 120,000 unique plant genomes across 27 species incorporated to-date. CropOS^® leverages this data library to accelerate Benson Hill's products to market, including its current non-GMO proprietary soy-based products;
• Integrated Business Model: Starting with the seed and through an integrated business model, the Company works with partners and growers to bring products to market that meet consumer needs for food that is healthier, more sustainable, more affordable and better tasting. Benson Hill deploys an innovative go-to-market approach that significantly reduces technological and product risk by using an integrated supply chain to ensure plant-to-plate traceability and preserve product identity;
• Driving Growth: The Company generated revenues of $102 million in 2020¹ and is projecting robust near-term growth, largely driven by existing products. The commercialization of innovative ingredient products is expected to deliver annual topline growth between 50% to 100% in the near-term. Over the longer-term, the Company expects its focus on production partnerships and royalties will help it scale and deliver products across numerous end-markets, including those in human plant-based food ingredients, animal feed, and pet food;
• Strong Financial Position: The pending transaction with Star Peak Corp II (NYSE: STPC) ("Star Peak"), is expected to fully finance the Company's forecasted growth plan. The merger transaction is expected to provide approximately $625 million in gross proceeds, comprised of Star Peak's $403 million of cash in trust, assuming no redemptions, and an oversubscribed and upsized $225 million common stock PIPE at $10.00 per share;
• Pure Play ESG Investment Opportunity: ESG is embedded in Benson Hill's product impact, culture, and long-term value.
