Asahi Kasei Corp has entered into a definitive merger agreement with ZOLL Medical Corp, a manufacturer of resuscitation and critical care devices and related software solutions, pursuant to which Asahi Kasei will acquire ZOLL for approximately $2.21 billion. The transaction has been approved by the Boards of Directors of both companies.

Asahi Kasei, through a US subsidiary, will make a cash tender offer to purchase all of the outstanding shares of ZOLL common stock for $93 per share. The purchase price represents a premium of 29.6% over ZOLL’s volume weighted average closing stock price over the 30 trading day period ended March 9, 2012, and a 23.8% premium over the closing price on March 9, 2012. The tender offer is expected to commence within 10 business days and will remain open for a minimum of 20 business days. Closing of the tender offer is subject to customary conditions, including receipt of applicable regulatory clearances and the minimum tender of at least two-thirds of the outstanding shares of ZOLL (on a fully diluted basis). The transaction is not subject to a financing condition. The ZOLL Board of Directors has recommended that ZOLL stockholders accept the offer and tender their shares into the offer when it is made.

Following the completion of the tender offer, Asahi Kasei intends to implement a second-step merger pursuant to which all remaining shares of ZOLL common stock not tendered in the offer will be converted into the right to receive the same cash price per share as in the offer. Upon completion of the merger, ZOLL will become a wholly owned subsidiary within the Asahi Kasei Group, managed by the current ZOLL management team and with all current business units and operations remaining intact. ZOLL will also be delisted from the NASDAQ stock exchange at that time.

Moving forward, Asahi Kasei plans strategic investments to accelerate the realization of ZOLL’s mission of leading the world in resuscitation technologies, and to build on the ZOLL platform to achieve Asahi Kasei’s long term strategic objective of creating a globally competitive health care business with a clear and unique focus on the field of critical care. Asahi Kasei has identified health care as a key strategic sector that will power a new phase of growth for the group, and believes that the acquisition represents a significant milestone in fulfilling its core vision for the health care sector: improving patient quality of life through the creation of innovative technologies and devices for critical care.
