SG Blocks, Inc. (NASDAQ:SGBX) ("SG Blocks" or the "Company"), a leading designer, innovator and fabricator of modular structures, today reported its financial results for the first quarter ending June 30, 2021.

"The second quarter was a momentous one for SG Blocks, as we achieved record quarterly revenues and made great strides in growing our activity across all verticals," said Paul Galvin, SG Blocks' Chairman and Chief Executive Officer. "In particular, we made substantial progress in our housing vertical, launching several new development opportunities where we anticipate earning revenue from both our interest in the projects and by fabricating the units at SG Blocks' own manufacturing facilities. These announcements provide greater visibility into our earnings over the next several quarters and put us on track to achieve positive cash flow in the fourth quarter of 2021.

"Our goals over the coming quarters will be to execute at a high level on our existing projects, seek new investment opportunities and partners, and continuously expand our manufacturing capacity to support our accelerating pace of activity. We are capturing the benefits of significant tailwinds in the residential development business by helping to deliver much-needed residential units to alleviate a housing shortage across the country. In our health care vertical, we also continue to provide critical health infrastructure with our modular and rapidly deployable COVID testing modules.

"In short, we are making our own destiny and rethinking the way space and buildings are used. We're continuing to close on developments and launching new projects and ventures each quarter. As our business has grown and our plan is unfolding, we have started to attract interesting, successful and notable partners, employees, and Board Members who share our passion for disrupting real estate and medical testing via safe and green modular solutions. We expect these efforts to pay off for our shareholders as we realize the value of these projects over time."

Second Quarter 2021 and Subsequent Operational Highlights:

At June 30, 2021, the Company had 14 projects under contract, compared to 16 projects under contract at March 31, 2021. At June 30, 2021, the construction backlog was approximately $21 million, as compared to approximately $22.9 million as of March 31, 2021. The Company's backlog does not include any projects related to recently launched SG Development Corp. and does not include ongoing medical testing.

As of June 30, 2021, SGB DevCorp. had active residential development projects for a total of 1,752 units.

Concentrated Market Activity

Medical Testing & Services

SG Blocks continues to provide innovative structures, labs, and testing solutions to support the fight against, and recovery from, the COVID-19 pandemic. The Company's modular solutions can be quickly and efficiently deployed at key locations for much-needed point-of-care patient access, to support the continue reopening and recovery of the U.S. economy.

In May, the Company partnered with Stone Clinical Laboratories to bring COVID-19 testing to Miami's South Beach area in connection with two events, Food Network's annual Wine & Food Festival, as well as the Air & Sea Show & Music Explosion.

Also in May, the Company's Chicago Area Testing subsidiary, in partnership with National Pain Centers, announced an agreement with the Robbins Park District of Robbins, IL to deploy a COVID-19 testing unit to provide health services to the underserved communities of the south suburbs of Chicago.

Manufacturing

After years of outsourcing, SG Blocks is committed to in-house manufacturing excellence. While there are a number of legacy project commitments that will be completed at a cash loss in 2021, going forward, the Company expects to manufacture future projects at a margin of approximately 15%.

SG Development Corporation

The Company formed SGB DevCorp. in February 2021 to deliver single family homes, townhomes, and for-rent apartment units across the country. The launch of SGB DevCorp. is expected to provide a host of benefits to SG Blocks, including: i) keeping manufacturing near 100% capacity to provide a steady and visible flow of manufacturing income, ii) participation in project fees, and; iii) potential profit from asset sales.

In May, SGB DevCorp. acquired a 50+acre site for its previously announced Lago Vista development, on Lake Travis, on the Colorado River in thriving Austin, Texas. The project is expected to consist of up to 225 one- and two-bedroom condominium units, as well as amenities including a community center, marina and health club. Development work is expected to commence in the second quarter of 2022, with an anticipated completion date in the fourth quarter of 2022. SG Blocks expects to capture approximately $25 million in manufacturing revenue over the life of the project. The Company also anticipates that its minority interest in the sale of the units will be no less than approximately $5.0 million as units are sold.

In June, the Company announced that SGB DevCorp. acquired a 50% membership interest to build a 138-unit, 125,000 square foot affordable housing community in East Point, GA within the Atlanta metropolitan area. The community will be known as "Norman Berry Village," and the units will be constructed at the Company's manufacturing facilities in Durant, OK and shipped to Atlanta. SGB DevCorp. has partnered with CMC Development Group, ZT Architecture & Land Development, and Community Development Consortium on the project. The Company expects to complete the project at a cost of approximately $15 million – $20 million. SGB DevCorp. will control the planning and construction process, and earn manufacturing revenue, as well as a share of development fees.

In June, the groundbreaking occurred on the previously announced Monticello Mews multifamily development project located in the Catskills region of New York. Upon completion, the development is expected to consist of 187 townhomes with one- and two-bedroom units, with amenities including a clubhouse, gym, and outdoor green spaces. The project is expected to be complete in the second quarter of 2023.

In June, the Company announced that SGB DevCorp. has acquired a 10% non-dilutable equity interest in JDI-Cumberland Inlet, LLC, a Georgia limited liability company, contributing $3,000,000 in capital to develop Cumberland Inlet, a 1,286 acre waterfront parcel in historic downtown St. Marys, Georgia. Modular housing units for the project will be produced at the Company's manufacturing facilities in Durant, OK, with gross potential manufacturing revenues totaling approximately $180 million, making St. Marys SGB DevCorp.'s largest project to date. The development is expected to commence site work in the fourth quarter of 2021, with initial deliveries of modular units expected in third quarter of 2022.

Use of Non-GAAP Financial Information

In addition to its results under GAAP, the Company presents EBITDA and Adjusted EBITDA for historical periods. EBITDA and Adjusted EBITDA are non-GAAP financial measures and have been presented as supplemental measures of financial performance that are not required by, or presented in accordance with, GAAP. The Company calculates EBITDA as net income (loss) before interest expense, income tax benefit (expense), depreciation and amortization. It calculates Adjusted EBITDA as EBITDA before certain non-recurring adjustments such stock-based compensation expense. EBITDA and Adjusted EBITDA are presented because they are important metrics used by management as one of the means by which it assesses the Company's financial performance. EBITDA and Adjusted EBITDA are also frequently used by analysts, investors and other interested parties to evaluate companies in the Company's industry. These measures, when used in conjunction with related GAAP financial measures, provide investors with an additional financial analytical framework that may be useful in assessing the Company and its results of operations.

EBITDA and Adjusted EBITDA have certain limitations. EBITDA and Adjusted EBITDA should not be considered as alternatives to net income (loss), or any other measures of financial performance derived in accordance with GAAP. These measures also should not be construed as an inference that the Company's future results will be unaffected by unusual or non-recurring items for which these non-GAAP measures make adjustments. Additionally, EBITDA and Adjusted EBITDA are not intended to be liquidity measures because of certain limitations, including, but not limited to: i) they do not reflect the Company's cash outlays for capital expenditures; They do not reflect changes in, or cash requirements for, working capital; and Although depreciation and amortization are non-cash charges, the assets are being depreciated and amortized and may have to be replaced in the future, and these non-GAAP measures do not reflect cash requirements for such replacements.

The non-GAAP information should be read in conjunction with the Company's consolidated financial statements and related notes.

The following is a reconciliation of EBITDA and Adjusted EBITDA to the nearest GAAP measure, net loss:

In evaluating EBITDA and Adjusted EBITDA, you should be aware that in the future we will incur expenses that are the same or similar to some of the adjustments made in our calculations, and our presentation of EBITDA and Adjusted EBITDA should not be construed to mean that our future results will be unaffected by such adjustment. Management compensates for these limitations by using EBITDA and Adjusted EBITDA as supplemental financial metrics and in conjunction with our results prepared in accordance with GAAP. The non-GAAP information should be read in conjunction with our consolidated financial statements and related notes.

The following is a reconciliation of EBITDA and Adjusted EBITDA to the nearest GAAP measure, net loss:
