HydroFlo, Inc. is a water treatment business in the United States.

The original Complaint charges that the Defendants HydroFlo and certain of its officers and directors violated sections 10(b) and 20(a) of the Exchange Act by issuing a series of false and misleading press releases to the market during the Class Period. Specifically, the Complaint alleges that HydroFlo issued several materially false and misleading press releases concerning Company's Metals & Arsenic Removal Technology, Inc. (MARTI) and Advance Water Recycle Inc., wholly owned portfolio companies. The Complaint charges that the Defendants misrepresented the type, terms, amendments, demand, and revenue projections from certain agreements between MARTI and EYI Industries and its subsidiaries during the Class Period. In addition, the Complaint alleges that Defendants misrepresented the existence and nature of certain agreements with government entities involved in the Hurricane Katrina relief effort. As a result of the Company's materially false and misleading statements to the market, according to the Complaint, the price of HydroFlo stock was artificially inflated in the Class Period.
