Asahi Kasei Corp. said Monday it has completed its tender offer to acquire Zoll Medical Corp., gathering some 93.8 percent of all the outstanding shares of the Chelmsford, Massachusetts-based medical equipment maker.
The offer, which began March 26, expired Friday.
In a subsequent offering period until the end of U.S. local time Wednesday, the diversified chemical maker hopes to acquire the remaining shares, it said.
The total acquisition cost is estimated at $2.21 billion.
Asahi Kasei has been in talks with Zoll on the deal since it began selling Zoll’s automated external defibrillator in Japan last August.
