SG Blocks, Inc. (the “Company”) was previously known as CDSI Holdings, Inc. (a Delaware corporation incorporated on December 29, 1993). On November 4, 2011, the Company’s wholly-owned subsidiary was merged with and into SG Building Blocks, Inc. (“SG Building”, formerly SG Blocks Inc.) (the “Merger”), with SG Building surviving the Merger and becoming a wholly-owned subsidiary of the Company. The Merger was a reverse merger that was accounted for as a recapitalization of SG Building as SG Building was the accounting acquirer. Accordingly, the historical financial statements presented are the financial statements of SG Building.

During 2011, the Company formed SG Blocks Sistema De Constucao Brasileiro LTDA. (“SG Brazil”), a wholly owned subsidiary of the Company. The Company formed SG Brazil in order to actively explore opportunities in Brazil. SG Brazil had been inactive since 2013. In May 2015, the Company formed Endaxi Infrastructure Group, Inc. (“Endaxi”), which is currently inactive.
