Tessenderlo Group says it will invest about $400 million to acquire roughly a 20% stake in FMC Corporation. The deal implies Tessenderlo becomes a significant minority investor in FMC while FMC retains control of its operations. The announcements describe the transaction as an investment by Tessenderlo to strengthen its position in FMC’s business and align with long-term corporate interests. Financial terms are reported consistently across the coverage: the purchase price is approximately $400 million and the stake size is about one-fifth of FMC’s equity. The sources do not provide additional details in the supplied excerpts on timing, regulatory approvals, or whether the stake is acquired through a specific share issuance or market transaction. Both outlets frame the announcement as a substantial capital commitment by Tessenderlo and a corresponding infusion of funds or support for FMC. Further details would typically be addressed in the companies’ full announcements, including closing conditions and any related governance rights associated with the stake.
