Bronstein, Gewirtz & Grossman, LLC is investigating potential claims on behalf of purchasers of the securities of Ener 1, Inc. (“Ener 1” or the “Company”) (NASDAQ: HEV), concerning whether the company and certain of its officers and directors have violated federal securities laws. The investigation relates to Ener 1’s August 15 th, 2011 disclosure that the Audit Committee of the Board of Directors of Ener 1, based upon a recommendation from management, determined that Company’s financial statements for year ending December 31, 2010 and quarterly period ended March 31, 2011, respectively should be restated and no longer relied upon. The company will need to restate its financial statements to reflect as of December 31, 2010 the impairments of its investment in Think Holdings (which had previously been recorded in the first quarter of 2011), its accounts receivable with Think Global and its loans receivable with Think Holdings, including accrued interest. On that news, the company’s stocks price dropped approximately 30 cents, or 42.25% to close at approximately 45 cents.
