Japan’s Eneos Holdings says it has decided to acquire US-based butadiene producer TPC Holdings through its wholly owned US subsidiary, to make TPC a wholly owned subsidiary of Eneos under its High Performance Materials Segment. The deal is expected to close in October 2026, pending regulatory approvals.
The deal will give Eneos Group the world’s third-largest butadiene production capacity. TPC is a leading North American producer of butadiene, raffinate, 1-butene and polybutene, holding significant market share across these products with petrochemical operations in Houston, Texas, along with terminal operations in Port Neches, Texas, and Lake Charles, Louisiana. .
The transaction will be implemented through a merger between the special purpose vehicle established under the US subsidiary and TPC, and the parties have entered into a merger agreement.
The business environment surrounding Japan’s domestic materials industry is undergoing significant changes, including declining demand due to population decline and shifts in the competitive landscape. Against this backdrop, the US materials industry is globally competitive, supported by access to low-cost shale gas-based feedstocks, and demand is expected to continue growing.
Eneos adds it has a long-standing track record of safe and stable operations in the C4 chemicals business, including butadiene. It has also expanded material business such as elastomers globally, and has its specialty in high-performance, high-value-added products, such as solution-polymerised styrene-butadiene rubber (S-SBR).
The group has identified the expansion of its C4 chemicals business in the US market and the strengthening of synergies with its materials business as a key growth strategy.
Eneos will, thus, have the world’s third-largest butadiene production capacity. By strengthening its business foundation in butadiene, a key feedstock for the materials business, it aims to enhance its supply capabilities and responsiveness to market fluctuations.
The transaction also contributes to further strengthening supply chain of materials from C4 chemicals to elastomers.
