The Law Firm of Weiss & Lurie Investigates the Acquisition of Martek Biosciences Corporation by Royal DSM N.V.

Weiss & Lurie, a national class action and shareholder rights law firm with offices in New York City and Los Angeles, is investigating possible breaches of fiduciary duty and other violations of law by members of the Board of Directors of Martek Biosciences Corporation (“Martek” or the “Company”) (NASDAQ: MATK) arising from the proposed acquisition of Martek by Royal DSM N.V. (“DSM”) (NYSE Euronext: DSM KON) for $31.50 per share. The transaction is valued at approximately $1.09 billion and is expected to close in the first half of 2011.

Weiss & Lurie is investigating whether Martek’s Board acted in shareholders’ best interests in approving the transaction, whether the Board adequately shopped the Company so as to maximize shareholder value, and if the Company has made proper disclosure to its shareholders.
