November 10, 2015 (Shareholders Foundation) - An investigation on behalf of investors, who currently hold shares of Dyax Corp. (NASDAQ:DYAX), was announced concerning whether the takeover of Dyax Corp. by Shire plc for $37.30 per share is unfair to NASDAQ:DYAX stockholders.

The investigation by a law firm concerns whether certain officers and directors of Dyax Corp. breached their fiduciary duties owed to NASDAQ:DYAX investors in connection with the proposed acquisition.

On November 2, 2015, Shire plc and Dyax Corp. (NASDAQ:DYAX) announced that Shire will acquire Dyax Corp. for $37.30 in cash per NASDAQ:DYAX share, for aggregate upfront consideration of approximately $5.9 billion.

Dyax shareholders may receive additional value through a non-tradable contingent value right (CVR) that will pay $4.00 in cash per Dyax share upon approval of DX-2930 in HAE, representing a potential additional$646 million in aggregate contingent consideration.

However, the investigation concerns whether the offer is unfair to NASDAQ:DYAX stockholders. More specifically, the investigation concerns whether the Dyax Board of Directors undertook an adequate sales process, adequately shopped the company before entering into the transaction, maximized shareholder value by negotiating the best price, and acted in the shareholders' best interests in connection with the proposed sale.

Dyax Corp. (NASDAQ:DYAX) reported that its annual Total Revenue rose from $48.74 million in 2011 to $81.72 million in 2014 and that its Net Loss of $34.60 million in 2011 declined to $11.88 million in 2014.
