UPDATE 1-Auxilium Pharma backs QLT deal, adopts poison pill after Endo's bid
(Adds detail, background, shares)
Sept 17 (Reuters) - Auxilium Pharmaceuticals Inc said it would not withdraw its offer to buy Canadian eye drug maker QLT Inc and adopted a poison pill, a day after receiving an unsolicited buyout offer from Endo International Plc.
Endo on Tuesday offered to buy Auxilium for $2.2 billion in cash and stock and Chief Executive Rajiv De Silva clarified the offer pertained to only Auxilium.
Auxilium's shares rose about 44 percent to $31 in premarket trading on Wednesday, above Endo's offer of $28.10. Endo's U.S.-listed shares rose about 5 percent.
QLT's shares fell 15 percent in after market trading on Tuesday, after analysts said Endo's offer could complicate Auxilium's buyout of QLT.
"Now that Auxilium is firmly in play, we expect the company's (mostly frustrated) shareholder base to push for a sale to the highest bidder," Cowen & Co analysts said in a note.
Auxilium said on Wednesday its would review Endo's proposal, but still adopted a poison pill with a 15 percent trigger.
Poison pills, or shareholder rights plans, are designed to stop hostile takeover attempts by triggering the issuance of new shares, which dilutes the holdings of all investors if any one exceeds a set threshold.
Endo's bid was made to expand its men's healthcare products business by gaining access to Auxilium's brands, including Xiaflex, which is approved to treat Peyronie's disease, Dupuytren's contracture, and frozen shoulder syndrome. Continued...
