Under the proposed agreement, the Consortium will acquire all of the outstanding shares of Tekelec for $11.00 per share in cash. The investigation concerns whether Tekelec’s board of directors adequately shopped the Company to obtain the best price possible for Tekelec’s shareholders before entering into the agreement with the Consortium. Indeed, according to Yahoo! Finance, at least one analyst has set a $16.00 per share price target for Tekelec stock.
