Clayton, Dubilier & Rice today announced the completion of the sale of Solenis, a leading global supplier of specialty chemicals and services for water treatment applications, to Platinum Equity. CD&R funds, which along with management owned 51% of Solenis, and chemical company BASF, which held the remaining 49%, both fully exited Solenis as part of the transaction. The total enterprise value was $5.25 billion.

CD&R funds acquired Solenis in July 2014 in a carve-out of the non-core operating subsidiary of Ashland, Inc. (NYSE: ASH) that ascribed an enterprise valuation of $1.8 billion to Solenis. In 2019, Solenis merged with BASF’s Paper & Water Chemicals business, creating a leading solutions provider for the pulp & paper and water treatment industries.

CD&R Partner Stephen Shapiro said, “We have been delighted with our investment in Solenis and our partnership with its talented team, which has achieved significant performance gains, expanded the company’s global presence, strengthened its customer offerings, and positioned it as a sustainability leader. These improvements have provided Solenis with a strong foundation for continued growth and a rewarding future.”
