ENEOS Holdings Acquires TPC Group in a $1.3 Billion Deal

Houston, August 8, 2026 — ENEOS Holdings, Inc., Japan’s leading energy company, has announced a definitive agreement to acquire TPC Group, the largest independent processor of C4 hydrocarbons in North America. The transaction is valued at an estimated $1.3 billion.

As part of the agreement, ENEOS will assume control of TPC Group’s petrochemical operations in Houston, Texas, along with key terminal facilities in Port Neches, Texas, and Lake Charles, Louisiana. TPC Group is a dominant player in the North American market, holding the top share in butadiene production—a critical raw material for synthetic rubber used in tires—as well as raffinate, 1-butene, and polybutene.

This acquisition marks a strategic milestone in ENEOS’s growth plan, aiming to establish it as the world’s third-largest producer of butadiene by production capacity. ENEOS believes the deal will enhance synergies between its existing crude C4 operations in Japan and TPC’s Gulf Coast infrastructure, providing a significant entry point into the U.S. petrochemical market, which is driven by advantaged shale-based feedstocks.

The transaction is slated to close in October 2026, subject to regulatory approvals. Until then, both companies will continue to operate independently.
