These companies drive innovation and maintain supply chain strength to meet increasing consumer demand.

Significant Acquisition Expanding Market Capabilities
In a notable development in November 2024, Arla Foods Ingredients Group P/S acquired the whey nutrition business from Volac Whey Nutrition Limited.
