PRAGUE, Feb 4 (Reuters) - Czech investment group PPF has launched an attempt to replace the management of Zentiva <
>, putting presure on a bid for the Czech generic drugs company by French Sanofi-Aventis <SASY.PA>.Zentiva said on Wednesday that PPF, its second largest shareholder after Sanofi, had asked a court to call a shareholder meeting at which PPF would propose firing the board and replacing several directors with its own nominees.
Zentiva said it would fight the legal action. Its board, led by chairman Jiri Michal, supports a Sanofi bid valuing the firm at $2 billion, or 1,150 crowns per share.
Purchasing Zentiva would take Sanofi, whose top selling drugs include blood-thinner Plavix and anti-thrombotic drug Lovenox, deeper into the field of generics, previously shunned by large pharmaceutical companies but now seen as an entry point to booming emerging markets.
"On the basis of all available information the board believes the legal proceedings that PPF has initiated are entirely without merit," Zentiva said.
Zentiva shares were down 1.2 percent at 1,120 crowns at 1125 GMT, while the main PX index <
> was up 0.4 percent.PPF, a closely-held investment group controlled by financier Petr Kellner, had no immediate comment but said it would issue a statement later.
PPF has withdrawn its own 950 crowns per share offer for Zentiva but has otherwise not reacted to the Sanofi bid.
Sanofi owns 24.9 percent of Zentiva while PPF controls a 24.3 percent stake, according to Zentiva, whose management holds 5.9 percent. Analysts said PPF may have wider control through other shareholders.
"It is probable that at this moment they control more than Sanofi and the management," said Josef Nemy, an analyst at Komercni Banka. "If they raise this demand, then probably they believe they will push it through."
Sanofi's bid is conditional on it acquiring a majority in Zentiva. Nemy said PPF's move showed it was not interested in selling to Sanofi at 1,150 crowns. "This fairly lowers the chance to get a majority (for Sanofi). So maybe it is a push from PPF how to increase the offer price," Nemy said.
Zentiva is set to hold an extraordinary shareholder meeting on the Sanofi bid on Feb. 9. The bid expires on Feb. 20. The European Commission was due to release a review Sanofi's offer on Wednesday.
Other Zentiva owners whose shares are in play include privately-owned investment group J&T with 7.6 percent and Belviport Trading Ltd, a closely-held firm with anonymous owners, with 10.06 percent.
PPF announced its acquisition of a part of J&T's core business last week but a J&T spokesman said the group's stake in Zentiva was not part of the deal. (Additional reporting by Jan Korselt; Editing by Will Waterman and Dan Lalor)
