SG Blocks Announces Pricing of $932,525 Financing

Company Strengthens Financial Position to Support Manufacturing and Commercial Activity

BROOKLYN, NY – April 25, 2019 – SG Blocks, Inc. (Nasdaq: SGBX) (“SG Blocks” or the “Company”), a leading designer, innovator and fabricator of container-based structures, today announced that it has entered into definitive agreements with certain institutional and accredited investors providing for the purchase and sale of 847,750 shares of common stock at a price of $1.10 per share and warrants to purchase up to 847,750 shares of common stock at an exercise price of $1.375 per share. The warrants will be exercisable six months following issuance and will expire five years from the date that the warrants become exercisable. The gross proceeds of the offering are expected to be approximately $932,525.

The offering is expected to close on or about April 29, 2019, subject to satisfaction of customary closing conditions. SG Blocks intends to use the net proceeds from the offering for working capital and general corporate purposes.

“This capital infusion not only fortifies our balance sheet, but also provides the necessary capital to execute on some near-term transformative projects that we believe will deliver significant revenue generation in the quarters to come,” said Paul Galvin, CEO of SG Blocks. “Since our public offering in June of 2017, SG Blocks has been militant on taking in the minimum amount of outside capital as possible to minimize future dilution for our shareholders. We look forward to providing a comprehensive update on our first quarter 2019 financial results conference call in May,” concluded Galvin.

Roth Capital Partners acted as the exclusive placement agent for this offering.

The shares of common stock were offered pursuant to a shelf registration statement on Form S-3 (File No. 333-228882), which was declared effective by the United States Securities and Exchange Commission (SEC) on February 7, 2019. The warrants and shares issuable upon exercise of the warrants were offered in a concurrent private placement and have not been registered under the Securities Act of 1933, as amended.

This press release does not constitute an offer to sell or the solicitation of an offer to buy, nor will there be any sales of these securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of such jurisdiction. A prospectus supplement relating to the shares of common stock will be filed by SG Blocks with the SEC.
