About Suann Guthrie
Suann Guthrie, Senior Vice President of Investor Relations, Sustainability & Global Communications at Darling Ingredients, has appeared on NYSE television programs in 2024 and 2025 to discuss the company’s business activities and strategy. In June 2025, she announced Darling Ingredients’ dual listing on the NYSE Texas exchange, stating the company would continue to trade under the ticker symbol DR on both exchanges. She described the move as providing greater exposure and flexibility, and noted that Darling Ingredients, which moved its headquarters to Dallas in 1986, wanted to be part of the NYSE’s relocation of its Chicago trading floor to Texas. Guthrie also discussed a joint venture with a company called Toenderloo to combine their collagen and gelatin businesses, which she said would create a $1.5 billion revenue company focused on the collagen-based health, wellness, and nutrition sector. In earlier appearances, Guthrie described Darling Ingredients as a company that recycles discards from the animal agriculture and food waste industries into ingredients for pet food, livestock feed, and human consumption, as well as feedstock for renewable diesel and sustainable aviation fuel. She stated that the company is a vertically integrated producer of renewable diesel through a 50-50 joint venture and that it shipped its first load of sustainable aviation fuel in the United States. Guthrie also outlined sustainability initiatives, including joining the Science Based Targets initiative (SBTi) to set emissions reduction goals, conducting a biodiversity risk assessment for U.S. facilities, and working to calculate a carbon avoidance number. She mentioned research and development on a proprietary enzymatic process to separate amino acid chains from collagen for health benefits, including a product intended to slow glucose absorption.
