EQT-backed Oterra, a supplier of natural colors, agreed to acquire Akay Group, a provider of natural colors and nutraceutical ingredients. Financial terms were not disclosed. "Akay is a great strategic match for Oterra. It adds to Oterra’s best-known core-strength – natural colors, and its portfolio of nutraceutical products complements Oterra’s existing portfolio of products for natural dietary supplements. The demand for all-natural products in this market is on the rise – and so is Oterra," Cees de Jong, Oterra Chairman.
