The merger will be a stock-for-stock transaction with Innovate shareholders owning about 91 percent of the combined company and Monster shareholders controlling about 9 percent. The preliminary proxy materials filed with the Securities and Exchange Commission included the merger agreement and the opinion of Benchmark Co. whether the transaction is fair to Monster shareholders. A definitive proxy statement containing information about the proposed transaction will be mailed to each Monster stockholder entitled to vote at the company’s stockholder meeting. Shares of Monster (MSDI) closed Friday up 39 cents, or more than 63 percent, to $1 on the Nasdaq.
