EnerNOC (ENOC) is off after hours following the announcement that it has filed a preliminary prospectus with the SEC to offer up to 3,750,000 shares of common stocks with proceeds being used for biz expansion, strengthening its working capital position, future acquisitions and R&D.  Considering the run the stock has had, the move isn’t much of a surprise.  ENOC will offer 3 mill of shares and certain shareholders will offer the rest.
