The description of the Escrow Agreement under Item 2.01 is hereby incorporated by reference into this Item 1.01.

On June 18, 2014, Great American Group, Inc. (the “Company”) completed its previously announced acquisition of B. Riley and Co. Inc. (“BRC”).

The Company acquired BRC pursuant to the terms of the Acquisition Agreement (the “Acquisition Agreement”), dated as of May 19, 2014, by and among the Company, Darwin Merger Sub I, Inc., a wholly owned subsidiary of the Company (“Sub I”), B. Riley Capital Markets, LLC, a wholly owned subsidiary of the Company (“BCM”), BRC, B. Riley & Co. Holdings, LLC (“BRH”), Riley Investment Management LLC (“RIM,” and collectively with BRC and BRH, the “B. Riley Entities”) and Bryant Riley, a director of the Company and the sole or principal owner of each of the B. Riley Entities (“Seller”).

Pursuant to the terms and conditions of the Acquisition Agreement, the Company agreed to acquire the B. Riley Entities in exchange for the issuance of 4,191,512 shares of its common stock (which represents the base purchase price of 4,200,000 shares of common stock, as adjusted for the estimated working capital adjustment set forth in the Acquisition Agreement). 3,751,264 of such shares were issued to Seller, 628,727 of which have been placed into an escrow account governed by the terms and conditions of an escrow agreement, dated as of June 18, 2014 by and among the Company, Seller and Continental Stock Transfer & Trust Company, Inc., as escrow agent (the “Escrow Agreement”). Such escrowed shares will serve as security for the indemnification obligations of Seller and the B. Riley Entities pursuant to the Acquisition Agreement and any downward adjustment to the merger consideration as a result of the final working capital adjustment provided for in the Acquisition Agreement.

In connection with the Company’s acquisition of BRC, Sub I merged with and into BRC, and BRC subsequently merged with and into BCM, with BCM surviving as a wholly owned subsidiary of the Company. The Company expects to complete the acquisitions of BRH and RIM by the end of the third quarter of 2014, subject to certain conditions.

As previously discussed in the Current Report on Form 8-K filed by the Company on May 19, 2014, effective upon the closing of the acquisition, (i) Bryant Riley has been appointed as the Company’s Chief Executive Officer and Chairman, (ii) Andrew Gumaer will continue to serve as the Chief Executive Officer of Great American Group, LLC and will no longer serve as the Company’s Chief Executive Officer and Chairman and (iii) Harvey Yellen will continue to serve as the President of Great American Group, LLC and will no longer serve as the Company’s President and Vice-Chairman.

An additional description of the Acquisition Agreement is contained in, and a copy of the same is filed as an exhibit to, the Current Report on Form 8-K filed by the Company on May 19, 2014 and is incorporated herein by reference.
