Burgess Pigment Co., a producer of specialty kaolin pigments and functional mineral products and Thiele Kaolin Company, jointly announced that the parties have entered into a definitive agreement where Burgess Pigment will acquire Thiele, a global supplier of kaolin clay and silica products. Financial terms of the transaction were not disclosed.

“Thiele is an exceptional business with a strong reputation for quality, reliability, and technical expertise,” said Sandy Burgess, president of Burgess Pigment. “The transaction will bring together two companies with complementary skills and product offerings and aligns closely with our long-term strategy to build a vertically integrated and differentiated specialty minerals platform. Together, we will be better positioned to better meet customer demand for consistent supply and to offer a broader range of high-performance solutions, while continuing to invest in our people, operations, and innovation capabilities.”

Upon completion of the transaction, Sandy Burgess will continue as CEO and president of Burgess Pigment. Eric Tillirson will continue to serve as president of Thiele. As part of the completion of the transaction, Thiele and Burgess Pigment will both become wholly-owned subsidiaries of a new holding company owned by Burgess Pigment’s existing shareholders.

The transaction is expected to close in 2026, subject to the receipt of shareholder and regulatory approvals, as well as other customary closing conditions.
