Management Commentary

“The first quarter of 2018 demonstrated continued progress and execution with our operating platform for construction,” said SG Blocks CEO Paul Galvin. “We achieved several operational milestones, and ended the quarter with sequential record backlog. This was mainly attributable to the second largest project award in the Company’s history for a major workforce housing project in Sullivan County, New York. This four-building, 190,000-square-foot multi-story, multi-family workforce housing development represents an estimated revenue opportunity of $27.5 million over the next three years. As of March 31, 2018, our construction backlog now stands at approximately $103.0 million, or approximately 700,000 square feet across 16 projects.

“Since our public offering in June 2017, we have focused on three primary areas:

Achieving cash flow positive operations;

Continuing to grow our backlog and pipeline of opportunities; and

Executing on our backlog to drive top-line revenue growth with a consistent 20% margin profile.

“As evidenced by our low first quarter 2018 cash burn rate of $0.4 million, any material increase in revenue will quickly achieve one of our key goals for 2018 – achieving and maintaining positive cash flow from operations. We believe the upcoming quarters are setting up to deliver significant top-line revenue growth as our backlog maintained steady momentum during the first quarter of 2018. In fact, we commenced activity on 10 projects in backlog and completed two projects in Q1 2018,” continued Galvin.

“SG Blocks anticipates it will recognize a major part of the residual contract of $1.9 million from the Los Angeles project in the second quarter of 2018 and based upon anticipated backlog conversion, the company believes revenue in the second quarter of 2018 will be in the range of $3.5 million to $4.5 million.

“Furthermore, and based on conversations with our customers for our three specific projects in excess of $10 million, we estimate revenue realization on our backlog as follows:

●

On the $15.0 million contract, management expects to recognize approximately 30% of the project revenue in 2018 and the balance in 2019.

●

On the $55.0 million contract, management expects to realize approximately 10% of the project revenue in 2018 and the remaining balance equally in each of 2019 and 2020.

●

On the $27.5 million contract, we expect to start design and engineering services in the fourth quarter of 2018.

“In addition to those three projects, management estimates that other contracts in our backlog and conversion of pipeline opportunities will translate into estimated revenue of $10.0-$15.0 million in 2018.

“Although our gross profit margin was muted in the first quarter of 2018, we anticipate subsequent quarters will transition from low-margin projects to an anticipated margin of 20% as we commence projects that are fully modular and encompass all three phases we offer: (1) design, (2) architectural and engineering and (3) construction and delivery,” said Galvin.

“We believe that, given the asset-light nature of our business model, we can handle incremental revenue with a relatively modest increase in general and administrative expenses. We leverage both inventory and labor of our platform partners and, in most cases, pay for products and services only after we have been paid by the customers. Our model creates significant leverage and reduces working capital constraints to growth.

“On the governance front, during the second quarter we proudly announced the appointment of Yaniv Blumenfeld to our board of directors. Mr. Blumenfeld is a 20-year real estate veteran with extensive commercial real estate loan and equity transaction experience. We expect to leverage his relationships in conjunction with SG Blocks’ business development initiatives and believe his experience as an entrepreneur and a veteran of the capital markets will further strengthen our board’s breadth of talent.

“As we enter the mid-point of the second quarter, we continue to advance and grow our pipeline of opportunities that now stands at approximately $275 million and includes multi-family residential, humanitarian residential, schools and hospitality projects in the United States and abroad. Since delivering our containers at the Heart of Los Angeles Community Arts and Recreation Center, in downtown Los Angeles, in March and April, we have received several inbound requests from developers to replicate similar projects in the area and across the United States. We believe adoption of our construction model is gaining momentum in the industry, as the value proposition as compared to traditional construction is very compelling.

“The Company continues to look for innovative ways to expand the operating platform in order to provide end to end modular solutions on a global basis that make business sense, vertically integrate and add value.

“We look forward to sharing more on our developing story at the soon to be announced Heart of Los Angeles Community Arts and Recreation Center Ribbon Cutting Ceremony and the 8^th Annual LD Micro Invitational on June 4-6, 2018 in Los Angeles, California,” concluded Galvin.

First Quarter 2018 Financial Results

Revenue in Q1 2018 totaled $1.5 million, an increase of 150% compared to $0.6 million in Q1 2017. This increase in revenue was primarily a result of revenue being recognized on additional projects that were in progress or completed during Q1 2018 as compared to Q1 2017. Revenue in Q1 2018, included $0.7 million from work in progress on a contract in the amount of approximately $5.6 million. The Company anticipates that the project will be largely complete in Q2 2018 and a majority of the residual contract revenue will be recognized in the quarter.

Construction backlog totaled $102.8 million at March 31, 2018, as compared to $76.7 million at December 31, 2017 and $0.8 million at March 31, 2017. The increase in backlog at the end of Q1 2018 as compared to the end of Q1 2017 was largely attributable to the signing of a 190,000-square-foot workforce housing development project. As of March 31, 2018, the company had 16 projects, or approximately 700,000 square feet, in backlog.

Gross profit totaled $163,596 in Q1 2018 as compared to $153,229 in Q1 2017. Gross profit margin as a percentage of revenue decreased to 11% in Q1 2018, as compared to approximately 26% in Q1 2017. Gross profit margin in Q1 2018 was negatively affected by lower contracted margins on a contract in the amount of approximately $5.6 million.

Operating expenses increased to $0.9 million in Q1 2018 from $0.8 million in Q1 2017. The increase in operating expenses was primarily due to an increase in headcount, professional fees and business development related expenses.

Net loss totaled $0.8 million, or $(0.18) per basic and diluted share, in Q1 2018, compared to net loss of $0.7 million in Q1 2017.

Adjusted EBITDA loss increased to $0.5 million in Q1 2018 from $0.3 million in Q1 2017. See below under the heading “Use of Non-GAAP Financial Information” for a discussion of adjusted EBITDA and a reconciliation of such measure to the most comparable measure calculated under U.S. generally accepted accounting principles (“GAAP”).

Cash and cash equivalents at March 31, 2018 totaled $4.5 million, as compared to $4.8 million at December 31, 2017.

Use of Non-GAAP Financial Information

In addition to our 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. We calculate EBITDA as net income (loss) before interest expense, income tax benefit (expense) depreciation and amortization. We calculate Adjusted EBITDA as EBITDA before certain non-recurring adjustments such as loss on conversion of convertible debentures, change in fair value of financial instruments and stock 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 our financial performance. EBITDA and Adjusted EBITDA are also frequently used by analysts, investors and other interested parties to evaluate companies in our 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 our Company and our results of operations.
