|Nature of Operations
Corbus Pharmaceuticals Holdings, Inc. (“CPHI” or “the Company”) is a clinical stage biopharmaceutical company, focused on the development and commercialization of therapeutics to treat rare life-threating, rare inflammatory fibrotic diseases. Since its inception, the Company has devoted substantially all of its efforts to business planning, research and development, recruiting management and technical staff, acquiring operating assets and raising capital. The Company’s business is subject to significant risks and uncertainties and the Company will be dependent on raising substantial additional capital before it becomes profitable and it may never achieve profitability.
JB Therapeutics Inc. (“JB Therapeutics”), was incorporated on April 24, 2009 under the laws of the State of Delaware. CPHI was incorporated on December 18, 2013 under the laws of the State of Delaware. On April 11, 2014, JB Therapeutics Inc. completed a reverse acquisition with CPHI. Upon the consummation of the reverse acquisition, JB Therapeutics became a wholly owned subsidiary of CPHI and changed its name to Corbus Pharmaceuticals, Inc. CPHI continues to operate the business of JB Therapeutics. All the references to the “Company” for activities prior to the reverse merger are to JB Therapeutics activities.
As part of the reverse acquisition, CPHI issued 9,000,000 shares of common stock to holders of JB Therapeutics common and preferred stock in exchange for a total of 5,964,649 common shares outstanding on an as converted basis. In addition, the holders of warrants to purchase common stock of JB Therapeutics received warrants, or the Replacement Warrants, to purchase 377,839 shares of CPHI common stock with an exercise price of ranging from $0.60 to $0.66. In addition, holders of JB Therapeutics Series A preferred stock received warrants to purchase 917,612 shares of common stock of CPHI. Finally, holders of outstanding options of JB Therapeutics received, in substitution for such options, options made pursuant to the Corbus 2014 Equity Incentive Plan to purchase an aggregate of 905,334 shares of CPHI common stock with exercise prices ranging from $0.11 to $0.17 per share. All share and per share amounts presented in these consolidated financial statements for the years ended December 31, 2014 and 2013 have been retroactively restated to reflect the 1.5089 exchange ratio of JB Therapeutics shares for CPHI shares in the reverse acquisition. Immediately prior to the reverse acquisition, CPHI had 6,000,000 shares outstanding.
The reverse acquisition was accounted for as a recapitalization since the formation of CPHI was formed solely to effect the reverse acquisition and a private placement of equity and CPHI had no prior operations or net monetary assets. Thus, JB Therapeutics is deemed to be the accounting acquirer and successor entity and the historical financial statements are those of JB Therapeutics as the accounting acquirer. Following the reverse acquisition, the management of JB Therapeutics became the management of CPHI. At the date of the reverse acquisition, the 6,000,000 outstanding shares of CPHI are reflected as an issuance of common stock to the prior holders of CPHI. CPHI had no net monetary assets as of the reverse acquisition so the issuance was recorded as a reclassification between additional paid-in-capital and par value of common stock. On April 11, 2014 and in three subsequent closings, CPHI completed a private placement of equity, raising net proceeds of approximately $8,402,000 (the “2014 Private Placement”) (See Note 9).
