On November 17, 2015, Energous Corporation (the “Company,” “we,” “us” and “our”) entered into an Underwriting Agreement (the “Underwriting Agreement”) with Ladenburg Thalmann & Co. Inc. and Roth Capital Partners, LLC, as the representatives of the several underwriters named therein (the “Underwriters”), relating to the issuance and sale of 2,608,700 shares of the Company’s common stock, par value $0.00001 per share. The shares are being sold at a public offering price of $6.90 per share, and the Underwriters have severally agreed to purchase the shares from us at a price of $6.486 per share. In addition, under the terms of the Underwriting Agreement, we have granted the Underwriters an option, exercisable for 30 days, to purchase up to an additional 391,305 shares of common stock. Also, we have agreed to pay Oppenheimer & Co., Inc. (“Opco”) $150,000 in connection with the offering in exchange for Opco waiving its right of first refusal to participate in the offering. The net proceeds to us from this offering are expected to be approximately $16.5 million, after deducting underwriting discounts and commissions, the amount payable to Opco, and other estimated offering expenses payable by us. The offering is expected to close on or about November 20, 2015, subject to customary closing conditions.

The offering is being made pursuant to our effective registration statement on Form S-3 (Registration Statement No. 333-203622) previously filed with the Securities and Exchange Commission and a prospectus supplement thereunder.
