The complaint asserts claims against defendants Dyadic International,
Inc., Mark A. Emalfarb, Stephen J. Warner, Harry Z. Rosengart, Richard
J. Berman, Robert B. Shapiro and Glenn E. Nedwin for violations of
Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and
Rule 10b-5 promulgated thereunder. The complaint alleges operational
and financial improprieties perpetrated by the Company and its Asian
subsidiaries, and knowingly and/or recklessly approved by the
defendants, which culminated in an internal investigation and
subsequent firing of the Company’s Chairman and Chief Executive Officer
Mark A. Emalfarb. As a result of the improprieties in the Company’s
Asian subsidiaries and the subsequent internal investigation, the
Company has abandoned its Asian operations and the Company’s stock,
which was artificially inflated as a result of the material omissions
and misstatements contained within the Company’s publicly filed
financial statements and reports, is no longer publicly traded and is
at risk of being delisted, resulting in total loss of equity for owners
of Dyadic’s securities.
