NOTE 16. STOCKHOLDERS’ EQUITY

On August 6, 2014, we announced the pricing of a public offering to sell 1.175 million shares of our common stock at a price of $4.50 per share. The underwriters for the offering were given an option to purchase up to an additional 176,250 shares at $4.50 per share to cover over allotments. On August 8, 2014, they exercised their option to purchase the 176,250 additional shares. The offering closed on August 11, 2014. The net proceeds we received from the offering, after deducting the underwriting discount and offering expenses paid by us, were $5.15 million, including the underwriter’s exercise of the overallotment.

As part of the underwriting agreement, we issued a warrant for 47,000 shares to the underwriter representing 4 percent of the number of shares of common stock sold in the offering at an issue price of $5.40 per share representing 120 percent of the public offering price of the shares of common stock. In conjunction with the registered offering, our common stock began trading on The NASDAQ Capital Market (“NASDAQ”) under the symbol EFOI on August 7, 2014. For a complete description of the details of the registered offering, reference is made to the registration statement on Form S-1 filed with the SEC on May 21, 2014 and amended on July 22, 2014, July 25, 2014 and August 4, 2014 and the final prospectus contained therein filed on August 6, 2014.
