Potts, founder and President of State SteelWorks, LLC (“State SteelWorks”) based in Atlanta, Georgia, to its board of directors. Mr. Potts’ appointment as an independent member increases the total number of board members to seven, with five independent members.

As President of State SteelWorks, Mr. Potts’ responsibilities include managing the strategic direction and operating performance of State SteelWorks. Prior to founding State SteelWorks, Mr. Potts served as Chairman of Verde Apartment Communities (“VAC”), previously a wholly-owned subsidiary of Verde Realty, a private REIT, involved in development, construction and management of upscale multi-family communities.

“I am truly pleased to announce the addition of Mr. Potts to our board of directors,” said Paul Galvin, Chairman and CEO of SG Blocks. “Jim brings an incredible breadth and depth of operating experience with him to SG Blocks, which we believe will not only prove invaluable in strategic decision making, but also in helping the company further develop its commercial presence with multi-family REIT customers as well. I look forward to working closely with Mr. Potts to strengthen our board and drive long-term shareholder value creation.”

Before joining VAC, Mr. Potts held a number of senior positions with Security Capital Group Incorporated (formerly NYSE:SCZ) until its sale to GE Capital. Those responsibilities included Co-Chairman and Chief Investment Officer of Security Capital Atlantic (formerly NYSE:SCA), an Atlanta-based equity REIT that owned, acquired, developed and operated income-producing multifamily communities in the south Atlantic, mid-Atlantic and mid-western regions of the United States, and President and Chief Operating Officer of Homestead Village Incorporated (formerly NYSE:HSD), an extended-stay hotel company which developed and operated 136 hotels across the continental U.S. Prior to joining the Security Capital Group Incorporated management team, Mr. Potts was a Senior Partner with Trammell Crow Residential and a member of its Management Board. Mr. Potts has been a director of Borderplex Realty Trust, a private REIT based in El Paso, Texas, since 2015.

“SG Blocks is a clear disruptor to the global construction industry, offering a proprietary, proven product that is faster to build, less expensive and more durable than traditional construction methods,” said Mr. Potts. “In my mind, SG Blocks is well positioned to continue to attract demand and build market share from legacy competitors. I am proud to join the SG Blocks board of directors and offer guidance to the experienced management team as the company continues its rapid pace of operational execution.”
