Backed by private equity firm Stirling Square Capital Partners, Sustainable Agro Solutions has acquired Ceres Biotics, which was founded in 2010, and specialises in biofertilizers and biostimulants based on microorganisms.

“Ceres has established itself as an innovator, with more than 550 proprietary strains, robust R&D capabilities, and a strong international profile, trading across more than 20 countries in Europe and beyond,” said today’s statement from Stirling Square.

With the support of Stirling Square since 2021, Sustainable Agro Solutions (SAS Group) has grown with acquisitions: Aqua do Brasil (September 2025), Pevesa Agroscience (December 2024), Biovert (July 2023).
