TORONTO, Nov 21 (Reuters) - Shares of Talison Lithium Ltd dropped more than 7 percent on Wednesday after suitor Rockwood Holdings Inc said it was not interested in a bidding war, even as Talison indicated it plans to open talks with a rival bidder.
Rockwood, a U.S.-based chemical producer, said late on Tuesday that Australian authorities had approved its C$724 million ($725.71 million) takeover of Perth-based, Toronto-listed Talison.
"With this approval, Rockwood has obtained all regulatory approvals," Chief Executive Seifi Ghasemi said in a statement. "Rockwood has no intention of engaging in a bidding process for the acquisition of Talison."
Talison recently completed an expansion at its flagship project in Australia and now has the capacity to produce nearly two-thirds of current global demand for lithium carbonate, which is used in smartphone and hybrid car batteries.
