(NASDAQ:RBAK) at a price of USD 25.00 net per share in cash. Ericsson and Redback previously announced that they had reached a definitive merger agreement for Ericsson to acquire Redback.

The Board of Directors of Redback has unanimously determined that the offer and the merger are advisable, fair to and in the best interests of Redback’s shareholders, approved the merger agreement and the transactions contemplated thereby, including the offer, and recommended that holders of shares of Redback common stock accept the offer and tender their shares in the offer.
