US fine chemicals producer Albemarle has completed its acquisition of Rockwood Holdings, first announced in July 2014.

In line with the merger agreement, Rockwood has become a wholly-owned subsidiary of Albemarle, which remains headed by Luke Kissam as CEO. The company has been delisted from the New York stock exchange.

"Our combined world-class team, expanded customer reach and increased diversity across end markets, technologies and geographies positions allows Albemarle to drive long-term growth," Kissam said.
