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

Founded in 1946 and headquartered in Sandersville, Georgia, Thiele is recognized for its mining and processing operations, broad product portfolio, and long-standing customer relationships across paper, packaging, coatings, construction materials, and other industrial applications. Thiele operates multiple mining and processing facilities throughout the U.S. and Europe and serves customers worldwide. 

“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.” 

“Burgess Pigment shares our commitment to customer service, product quality, and operational excellence,” said Eric Tillirson, President of Thiele Kaolin Company. “This combination provides significant efficiencies, additional resources and scale to support our customers and employees and offers our shareholders liquidity for their investment while preserving the values and culture that have defined Thiele for decades.” 

The transaction brings together two highly complementary kaolin businesses with shared histories in Sandersville, Georgia – one of the world’s most important kaolin-producing regions. The combined company will offer an expanded portfolio of kaolin products and enhanced technical and R&D capabilities to support customers’ evolving performance and sustainability requirements. 

Upon completion of the transaction, Burgess, will continue as Chief Executive Officer and President of Burgess Pigment. 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.
