SK Capital, First Reserve Corp. Acquire TPC Group

New York City-based private equity firm SK Capital Partners, in partnership with global investment
firm First Reserve Corp., has acquired TPC Group Inc. — a Houston-based producer of value-added
products derived from niche petrochemical raw materials, and a provider of critical infrastructure
and logistics services to the Gulf Coast region.

TPC Group sells its products to performance, specialty and intermediate markets such as
synthetic rubber, fuels, lubricant additives, plastics and surfactants. The company is the largest
U.S. producer of finished butadiene, which is used in Wichita, Kan.-based Invista’s nylon 6,6
production process.

TPC Group operates manufacturing facilities in Texas in Houston, Port Neches and Baytown; and
in Lake Charles, La.

SK Capital, which focuses its investments on the specialty materials, chemicals, and
healthcare sectors, has stated that “the acquisition is consistent with [our] strategy of focusing
on sectors we know well, leveraging our knowledge and relationships to identify attractive
opportunities that have complexity and underperformance relative to their potential, and employing
impactful resources to support the successful execution of our investment strategies.”
