ENEOS Holdings has completed its acquisition of TPC Group, the Houston-based processor of C4 hydrocarbons, for US$758m, the Japanese group said on 27 October 2026. The deal closed on 26 October US time, and TPC said on 27 October that its acquisition was complete.
Why ENEOS Holdings, Inc. (via ENEOS Holdings USA Inc.) is buying TPC Holdings, Inc. (TPC Group)
ENEOS said the deal is part of the portfolio restructuring in its fourth medium-term plan. It wants to expand its C4 chemicals business in the US, where shale-gas feedstock is cheap, and to secure butadiene, the main raw material for its elastomers business. ENEOS said the acquisition lifts its butadiene capacity into the global top three.
“The completion of this transaction marks a significant step toward strengthening our business foundation in North America and accelerating our global growth”
Deal terms and financing
TPC Holdings merged with a wholly owned US subsidiary of ENEOS, and existing TPC shares were cancelled in exchange for cash. ENEOS put the acquisition price at US$758m. Redwood Capital Management was TPC's largest shareholder.
Regulatory approvals and timing
The companies had said all regulatory approvals were expected in October 2026. Completion has now taken place.
Market context
TPC Group operates petrochemical plants in Houston and terminals in Port Neches, Texas, and Lake Charles, Louisiana, and reported sales of about US$1.5bn to US$1.7bn a year over the past three years. ENEOS Materials will integrate operations with TPC, and Ed Dineen stays on as TPC's president and chief executive.
