ZURICH (Reuters) - Johnson & Johnson <JNJ.N> declared its $30 billion tender offer for Swiss biotechnology company Actelion <ATLN.S> successful on Friday, reporting it controlled 77.2 percent of the voting rights after the main offer period.


The price of the offer, which J&J announced on Jan. 26, was $280 per share for Actelion. It said it expected the transaction to close in the second quarter.


J&J has said it intends to delist Actelion, while a new research and development company being spun out of Actelion, to be called Idorsia and led by Actelion founder Jean-Paul Clozel, will have a separate Swiss listing.
