SG BLOCKS, INC. AND SUBSIDIARIES

Notes to Condensed Consolidated Financial Statements

For the Six Months Ended June 30, 2021 and 2020 (Unaudited)

1. Description of Business 

SG Blocks, Inc. (collectively with its subsidiaries, the “Company,” “we”, “us” or “our”) was previously known as CDSI Holdings, Inc., a Delaware corporation incorporated on December 29, 1993. On November 4, 2011, CDSI Merger Sub, Inc., 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. 

The building products developed with our proprietary technology and design and engineering expertise are generally stronger, more durable, environmentally sensitive, and erected in less time than traditional construction methods. The use of the SGBlocks building structure typically provides between four to six points towards the Leadership in Energy and Environmental Design (“LEED”) certification levels, including reduced site disturbance, resource reuse, recycled content, innovation in design and use of local and regional materials. Due to the ability of SGBlocks to satisfy such requirements, we believe the products produced utilizing our technology and expertise is a leader in environmentally sustainable construction.

There are three core product offerings that utilize our technology and engineering expertise. The first product offering involves GreenSteel™ modules, which are the structural core and shell of an SGBlocks building. We procure the containers, engineer required openings with structural steel enforcements, paint the SGBlocks and then deliver them on-site, where the customer or a customer’s general contractor will complete the entire finish out and installation. The second product offering involves replicating the process to create the GreenSteel product and, in addition, installing selected materials, finishes and systems (including, but not limited to floors, windows, doors, interior painting, electrical wiring and fixtures, plumbing outlets and bathrooms, roofing system) and delivering SGBlocks pre-fabricated containers to the site for a third party licensed general contractor to complete the final finish out and installation. Finally, the third product offering is the completely fabricated and finished SGBlocks building (including but not limited to floors, windows, doors, interior painting, electrical wiring and fixtures, plumbing outlets and bathrooms, roofing systems), including erecting the final unit on site and completing any other final steps. The building is ready for occupancy and/or use as soon as installation is completed. Construction administration and/or project management services are typically included in our product offerings.

The Company also provides engineering and project management services related to the use and modification of Modules in construction. 

During 2020, the Company formed, SG Echo, LLC, a wholly owned subsidiary of the Company. SG Echo, LLC was formed to complete the business acquisition as disclosed in Note 9. The Company acquired substantially all the assets of Echo DCL, a Texas limited liability company, except for Echo's real estate holdings for which we obtained a right of first refusal. Echo is a container/modular manufacturer based in Durant, Oklahoma specializing in the design and construction of permanent modular and temporary modular buildings and was one of the Company's key supply chain partners. Echo caters to the military, education, administration facilities, healthcare, government, commercial and residential customers. This acquisition has allowed the Company to expand its reach for the Modules and offer an opportunity to vertically integrate a large portion of the Company's cost of goods sold, as well as increase margins, productivity and efficiency in the areas of design, estimating, manufacturing and delivery and to become the manufacturer of the Company's core container and modular product offerings.  The Company also entered into a joint venture with Clarity Lab Solutions LLC., to provide clinical lab testing related to COVID-19.

As of January 2021, the Company’s condensed consolidated financial statements include the accounts of Chicago Airport Testing LLC (“CAT”). The Company has a variable interest in CAT as described further below. CAT is in the business of marketing, selling, distributing leasing and otherwise commercially exploiting certain products and services in the COVID-19 testing and other medical industry.

In addition, during 2021, the Company formed SGB Development Corp. (“SGB Development”), which is wholly-owned by the Company. SGB Development was formed with the purpose of real property development utilizing the Company's technologies.  SGB Development has a minority interest in Norman Berry II Owners LLC and JDI-Cumberland Inlet LLC as described further below.

SG BLOCKS, INC. AND SUBSIDIARIES

Notes to Condensed Consolidated Financial Statements

For the Six Months Ended June 30, 2021 and 2020 (Unaudited)

Reverse Stock Split

On February 5, 2020, the Company effected a 1-for-20 reverse stock split of its then-outstanding common stock, which has since been converted. All share and per share amounts set forth in the condensed consolidated financial statements of the Company have been retroactively restated to reflect the 1-for-20 reverse stock split as if it had occurred as of the earliest period presented and unless otherwise stated, all other share and per share amounts for all periods presented in these condensed consolidated financial statements have been adjusted to reflect the reverse stock split effected in February 2020.

As of June 30, 2021, the Company had 8,822,489 shares of common stock issued and outstanding.

2. Liquidity 

As of June 30, 2021, the Company had cash and cash equivalents of $2,323,599 and a backlog of approximately $21 million. See Note 12 for a discussion of construction backlog. Based on our conversations with key customers, the Company anticipates its backlog to convert to revenue over the following period: 

	2021
Within 1 year	$	8,179,581
1 to 2 years		12,856,250
Total Backlog	$	21,035,831

The Company has incurred losses since its inception and has negative operating cash flows. Management has taken several actions to ensure that the Company will continue as a going concern. As described below, the Company has been able to raise substantial cash through equity offerings. In addition, as further described in these consolidated financial statements, the Company has begun to recognize revenue from new revenue streams. Management believes that these actions will enable the Company to continue as a going concern.  

The Company completed a public offering in April and May 2020, which resulted in net proceeds of approximately $1,522,339, and $15,596,141, respectively. See Note 13 for a discussion on these public offerings. The Company believes that it has adequate cash balances to meet obligations coming due in the next twelve months and further intends to meet its capital needs from revenue generated from operations and by containing costs, entering into strategic alliances, as well as exploring other options, including the possibility of raising additional debt or equity capital as necessary. There is, however, no assurance the Company will be successful in meeting its capital requirements prior to becoming cash flow positive.  The Company does not have any additional sources secured for future funding, and if it is unable to raise the necessary capital at the times it requires such funding, it may need to materially change its business plan, including delaying implementation of aspects of such business plan or curtailing or abandoning such business plan altogether.   

With the global spread of the ongoing novel coronavirus ("COVID-19") pandemic during 2020, the Company implemented business continuity plans designed to address and mitigate the impact of the COVID-19 pandemic on its employees and business. Any quarantines, the timing and length of containment and eradication solutions, travel restrictions, absenteeism by infected workers, labor shortages or other disruptions to the Company's suppliers and contract manufacturers or customers would likely adversely impact the Company's sales and operating results and result in further project delays. In addition, the pandemic could result in an economic downturn that could affect the demand for the Company's products. Order lead times could be extended or delayed and pricing could increase. Some products or services may become unavailable if the regional or global spread were significant enough to prevent alternative sourcing. Accordingly, the Company is considering alternative product sourcing in the event that product supply becomes problematic. The Company expects this global pandemic to have an impact on the Company's revenue and results of operations, the size and duration of which the Company is currently unable to predict. In addition, to the extent the ongoing COVID-19 pandemic adversely affects the Company's business and results of operations, it may also have the effect of heightening many of the other risks and uncertainties which the Company faces. The Company has been impacted by COVID-19 with supply chain distributions, absenteeism by infected workers and skilled labor shortages which has caused delays in projects and the Company could be further impacted if the COVID-19 pandemic continues.

Notes to Condensed Consolidated Financial Statements

For the Six Months Ended June 30, 2021 and 2020 (Unaudited)

3. Summary of Significant Accounting Policies

Basis of presentation and principals of consolidation – The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions to the Current Report on Form 10-Q and Article 8 Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for annual financial statements. The condensed financial statements and notes should be read in conjunction with the consolidated financial statements and notes for the year ended December 31, 2020 included in the Company's Annual Report on Form 10-K for the year ended December 31, 2020, as filed with the Securities and Exchange Commission on April 15, 2021. In the opinion of management, all adjustments, consisting of normal accruals, considered necessary for a fair presentation of the interim financial statements have been included. Results for the six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021.

Recently adopted accounting pronouncements - New accounting pronouncements implemented by the Company are discussed below or in the related notes, where appropriate.

Accounting estimates – The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Significant areas that require the Company to make estimates include revenue recognition, stock-based compensation, stock warrants liabilities and allowance for credit losses. Actual results could differ from those estimates.

Operating cycle – The length of the Company’s contracts varies, but is typically between six to twelve months. In some instances, the length of the contract may exceed twelve months. Assets and liabilities relating to contracts are included in current assets and current liabilities, respectively, in the accompanying balance sheets as they will be liquidated in the normal course of contract completion, which at times could exceed one year.

Revenue recognition – The Company determines, at contract inception, whether it will transfer control of a promised good or service over time or at a point in time, regardless of the length of contract or other factors. The recognition of revenue aligns with the timing of when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. To achieve this core principle, the Company applies the following five steps in accordance with its revenue policy:

                (1)  Identify the contract with a customer

                (2)  Identify the performance obligations in the contract

                (3)  Determine the transaction price

                (4)  Allocate the transaction price to performance obligations in the contract

                (5)  Recognize revenue as performance obligations are satisfied

On certain contracts, the Company applies recognition of revenue over time, which is similar to the method the Company applied under previous guidance (i.e. percentage of completion). Due to uncertainties inherent in the estimation process, it is possible that estimates of costs to complete a performance obligation will be revised in the near-term. For those performance obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress toward complete satisfaction of the performance obligation, are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. When the current estimate of total costs for a performance obligation indicate a loss, a provision for the entire estimated loss on the unsatisfied performance obligation is made in the period in which the loss becomes evident.

3. Summary of Significant Accounting Policies (continued)

For product or equipment sales, the Company applies recognition of revenue when the customer obtains control over such goods, which is at a point in time.

On October 3, 2019, the Company entered into an Exclusive License Agreement (“ELA” ) pursuant to which it granted an exclusive license for its technology as outlined in the ELA. The ELA is described below. Under the ELA, the Company will receive royalty payments based upon gross revenues earned by the licensee for commercialized products within the field of design and project management platforms for residential use, including single-family residences and multi-family residences, but excluding military housing. The Company has determined that the ELA grants the licensee a right to access the Company’s intellectual property throughout the license period (or its remaining economic life, if shorter), and thus recognizes revenue over time as the licensee recognizes revenue and the Company has the right to payment of royalties. No revenue has been recognized under the ELA for the six months ended June 30, 2021 and 2020. On June 15, 2021, the Company terminated the ELA that was executed on October 3, 2019 which is discussed below.   

CMC Right of First Refusal Agreement – On October 9, 2019, the Company entered into a Right of First Refusal Agreement (the “Agreement”) with CMC Development LLC (“CMC”), which has a term of two (2) years. Under the Agreement, the Company has a right of first refusal with respect to being engaged as a designer and builder of any real estate projects for which CMC has secured the rights to develop and in which CMC has a greater than fifty percent (50%) interest in the owner or developer entity and has the right to select the builder for such real estate project (the “ROFR Rights”). In exchange for such ROFR Rights, the Company agreed to issue to CMC 2,500 shares of restricted stock of the Company’s common stock, of which 1,250 shares vested on March 31, 2021 and the remaining 1,250 shares will vest and be issued on September 30, 2021, unless the Agreement is earlier terminated. In the event that the Agreement is earlier terminated, CMC will still be entitled to receive the entire amount of such restricted stock that has vested as of such earlier termination date, but in no event less than 1,250 shares of such restricted stock. The Agreement also provides for customary indemnification and confidentiality obligations between the parties. The 2,500 shares of restricted stock of the Company's common stock has yet to be issued to CMC. 

The Agreement also provides that CMC has engaged the Company to build and design, in the aggregate, approximately 100 residential and commercial units at 1100 Ridge Avenue, Atlanta, Georgia, which is known as the “Ridge Avenue, Atlanta Project.” The total expected gross revenue to the Company for the project to be derived by CMC is approximately $16,900,000. The project is a residential project but it was not subject to the recently terminated Exclusive License Agreement, dated October 3, 2019. The planning stage of the project was initial delayed due to COVID-19 but the project is still active. No revenue has been recognized under the Agreement for the six months ended June 30, 2021 or 2020. 

The Company entered into a joint venture agreement with Clarity Lab Solutions, LLC (“Clarity Labs”) (the “JV”) in the fourth quarter of 2020. Revenue from the activities of the JV is related to clinical testing services and is recognized when services have been rendered, which is at a point in time.  Included in the consideration the Company expected to be entitled to receive, the Company estimates its contractual allowances, payer denials and price concessions. During the six months ended June 30, 2021, the Company recognized approximately $15,000,000 related to activities through the JV, which is included in medical revenue on the accompanying consolidated statements of operations. In addition, the Company formed Chicago Airport Testing, LLC which is currently collecting rental revenue from subleasing to a consortium of government entities assisting in COVID-19 testing. 

Disaggregation of Revenues

The Company’s revenues are derived from construction and engineering contracts related to Modules, and medical revenue derived from lab testing and test kit sales. The Company's contracts are with customers in various industries. Revenue recognized at a point in time and recognized over time were $15,750,903 and $5,290,711, respectively, for the six months ending June 30, 2021. All revenue recognized for the six months ending June 30, 2020 was over time.

Contract Assets and Contract Liabilities

Accounts receivable are recognized in the period when the Company’s right to consideration is unconditional. Accounts receivable are recognized net of an allowance for credit losses. A considerable amount of judgment is required in assessing the likelihood of realization of receivables.

The timing of revenue recognition may differ from the timing of invoicing to customers. 

Contract assets include unbilled amounts from long-term construction services when revenue recognized under the cost-to-cost measure of progress exceeds the amounts invoiced to customers, as the amounts cannot be billed under the terms of our contracts. Such amounts are recoverable from customers based upon various measures of performance, including achievement of certain milestones, completion of specified units or completion of a contract. Contract assets are generally classified as current within the condensed consolidated balance sheets.  

Contract liabilities from construction and engineering contracts occur when amounts invoiced to customers exceed revenues recognized under the cost-to-cost measure of progress. Contract liabilities additionally include advanced payments from customers on certain contracts. Contract liabilities decrease as the Company recognizes revenue from the satisfaction of the related performance obligation. Contract liabilities are generally classified as current within the condensed consolidated balance sheet. 

Although the Company believes it has established adequate procedures for estimating costs to complete on open contracts, it is at least reasonably possible that additional significant costs could occur on contracts prior to completion. The Company periodically evaluates and revises its estimates and makes adjustments when they are considered necessary.

Deferred Contract Costs - Prior to entering into the ELA, the Company was subject to an agreement to construct and develop a certain property (“Original Agreement”), which now was subject to the ELA. Because of this, the Company is no longer obliged to its Original Agreement. Upon entering the ELA, the Company had an outstanding accounts receivable balance of $306,143, which was forfeited and recognized this amount as deferred contract costs. This amount was offset by $102,217, which was reimbursement from the licensee for project costs on this project.  The Company incurred total deferred contract costs of $203,926.  The Company considered this amount an incremental cost of obtaining that ELA, because the Company expected to recover those costs through future royalty payments. The Company initially planned to amortize the asset over sixty months, which is the initial term of the ELA because the asset relates to the services transferred to the customer during the contract term. As of June 30, 2021, accumulated amortization related to deferred contract costs amounted to $71,374. During the six months ended June 30, 2021 and 2020, amortization expense relating to the deferred contract costs amounted to $20,392 and $20,393, respectively, and is included in general and administrative expenses on the accompanying condensed consolidated statement of operations.  As previously mentioned, the ELA was terminated on June 15, 2021 but the Company expects to recover the deferred contract costs from the Assignment of Limited Rights Under Membership Interest Redemption Agreement, dated June 15, 2021 as described below.  

Exclusive License Agreement – On October 3, 2019, as amended on October 17, 2019, the Company entered into the ELA with CPF GP 2019-1 LLC (the “Licensee”), pursuant to which the Company granted the Licensee an exclusive license (the “License”) solely within the United States and its legal territories to the Company’s technology, intellectual property, any improvements thereto, and any related permits, in order to develop and commercialize products within the field of design and project management platforms for residential use, including single-family residences and multi-family residences, but excluding military housing. The Ridge Avenue Project has also been excluded from the License. The License Agreement had an initial term of five (5) years and was to automatically renew for subsequent five (5) year periods. The License Agreement provided for customary terminating provisions, including the right by the Company to terminate if the Licensee fails to make minimum royalty payments (as described below).

3. Summary of Significant Accounting Policies (continued)

In consideration for the License, during the initial term, the Licensee agreed to pay the Company a royalty of (x) five percent (5%) on the first $20,000,000 of gross revenues derived from the Licensee’s commercialization of the License (net of customary discounts, sales taxes, delivery charges, and amounts for returns) (the “Gross Revenues”), (y) four and one-half percent (4.5%) on the next $30,000,000 of Gross Revenues, and (z) five percent (5%) on all Gross Revenues thereafter (collectively, the “Royalty”) , subject to the following minimum royalty payments determined on a cumulative basis during the initial term: $500,000 in year 1, $750,000 in year 2, $1,500,000 in year 3, $2,000,000 in year 4, and $2,500,000 in year 5. License Agreement provided that if it was extended beyond the initial term, then the parties would negotiate in good faith the royalty rate and the minimum royalty payments for the renewal term(s). In addition, to the extent the Licensee sublicenses any aspect of the License to a sub-licensee, the Licensee was obligated to pay to the Company fifty percent (50%) of all payments received by the Licensee from such sublicensee. The License Agreement also provided that the Company could also provide the Licensee with professional services with respect to the License, and the Licensee was obligated to the Company for employees’ time, materials, and expenses incurred in providing such professional services. The Licensee also separately agreed to reimburse the Company for any third-party expenses incurred by the Company in developing the Company’s remaining and future residential projects. 

The License Agreement provided for customary indemnification obligations between the parties and further provides that the Licensee will indemnify the Company for any claims arising out of the commercialization of the License by the Licensee or any of its subsidiaries, contractors, or sublicensees. In addition, the License Agreement provided that the Company would provide the Licensee with cost estimates for the fabrication and manufacturing of residential projects in the Company’s existing pipeline as of the date of the License Agreement, and if such projects cannot be reasonably constructed and installed at or below such estimates, then the Licensee may withhold payment of any royalty due to the Company under the License Agreement on a dollar-for-dollar basis to offset the costs above the originally estimated amounts.

On June 15, 2021, the Company terminated the Exclusive License Agreement with CPF that the Company had entered into on October 3, 2019.  In connection with the termination, the Company entered into a Settlement and Mutual Release Agreement (the “Settlement Agreement”) with CPF, the general partner (the “Licensee”) of CPF MF 2019-1 LLC (“CPF MF”), and Capital Plus Financial, LLC, a limited partner of the Licensee (“Capital Plus”) and an Assignment of Limited Rights Under Membership Interest Redemption Agreement, dated June 15, 2021, with Capital Plus and the Licensee. In connection with the termination of that certain Exclusive License Agreement, dated as of October 3, 2019 (the “License Agreement”), with the Licensee Pursuant to the Settlement Agreement with CPF and Capital Plus, the License Agreement was terminated, the Company released CPF and CPF MF for any claims in exchange for releases from CPF and Capital Plus and the Company is receiving an assignment of CPF’s right under certain circumstances to a $1.25 million redemption distribution from CPF MF under its Operating Agreement.

Business Combinations - The Company accounts for business acquisitions using the acquisition method of accounting in accordance with ASC 805 “Business Combinations”, which requires recognition and measurement of all identifiable assets acquired and liabilities assumed at their fair value as of the date control is obtained. The Company determines the fair value of assets acquired and liabilities assumed based upon its best estimates of the acquisition-date fair value of assets acquired and liabilities assumed in the acquisition. Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired. Subsequent adjustments to fair value of any contingent consideration are recorded to the Company’s condensed consolidated statements of operations. Costs that the Company incurs to complete the business combination are charged to general and administrative expenses as they are incurred.

Variable Interest Entities – The Company accounts for certain legal entities as variable interest entities (“VIE"). When evaluating a VIE for consolidation, the Company must determine whether or not there is a variable interest in the entity. Variable interests are investments or other interests that absorb portions of an entity’s expected losses or receive portions of the entity’s expected returns. If it is determined that the Company does not have a variable interest in the VIE, no further analysis is required and the VIE is not consolidated. If the Company holds a variable interest in a VIE, the Company consolidates the VIE when there is a controlling financial interest in the VIE and therefore are deemed to be the primary beneficiary. The Company is determined to have a controlling financial interest in a VIE when it has both the power to direct the activities of the VIE that most significantly impact the VIE economic performance and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to that VIE. This determination is evaluated periodically as facts and circumstances change.

3. Summary of Significant Accounting Policies (continued)

On August 27, 2020 the Company entered into a joint venture agreement with Clarity Lab Solutions, LLC (“Clarity Labs”) (the “JV”).  In consideration and subject to Clarity Lab’s services and commitments and provided the agreement remains valid and in force, and is not terminated, the Company agreed to issue 200,000 restricted shares of SGB common stock over a defined vesting period starting in December 1, 2020. The restricted shares of SGB common stock were not issued to Clarity Labs as certain capital commitments were not met. Clarity Labs is a licensed clinical laboratory that uses specialized molecular testing equipment and that focuses on the diagnosis and treatment of critical diseases, including COVID-19. Clarity Labs is also engaged in the business of manufacturing, importing and distributions various medical tests. Under the JV, the Company and Clarity Labs will jointly market, sell, and distribute certain products and services (“Clarity Mobile Venture”).  As of June 30, 2021, $381,770 was due to Clarity Labs for expenses paid on behalf of Clarity Mobile Venture, and is included in Due to Affiliates on the accompanying consolidated balance sheets. In addition, during the six months ended June 30, 2021, the Company recognized revenue of $60,110 and other income of $60,000 to Clarity Labs, of which $60,000 is included in accounts receivable as of June 30, 2021. The Company has determined it is the primary beneficiary of Clarity Mobile Venture and has thus consolidated the activities in its condensed consolidated financial statements.

On January 18, 2021 the Company entered into an operating agreement to form CAT. The purpose of CAT is to market, sell, distribute, lease and otherwise commercially exploit certain products and services in the COVID-19 testing industry.  The Company has determined it is the primary beneficiary of CAT and has thus consolidated the activities in its condensed consolidated financial statements.

Investment Entities – On May 31, 2021, the Company's subsidiary SGB Development Corp. agreed to contribute $600,000 to acquire a 50% membership interest in Norman Berry II Owner LLC.  The Company contributed $350,329 of the initial $600,000 in the second quarter of 2021 with the remaining amount being funded in the third quarter of 2021.   The purpose of Norman Berry II Owner LLC is to develop and provide affordable housing in the Atlanta, Georgia metropolitan area.  The Company has determined it is not the primary beneficiary of "Norman Berry" and thus will not consolidate the activities in its condensed consolidated financial statements. The Company will use the equity method to report the activities as an investment in on its condensed consolidated financial statements. 

On June 24, 2021, the Company's subsidiary SGB Development Corp. entered into an operating agreement with Jacoby Development for a 10% non-dilutable equity interest for JDI-Cumberland Inlet, LLC.  The Company contributed $3,000,000 for its 10% equity interest.  The purpose of JDI-Cumberland Inlet, LLC is to develop a waterfront parcel in a mixed-use destination community.  The Company has determined it is not the primary beneficiary of JDI-Cumberland Inlet, LLC and thus will not consolidate the activities in its condensed consolidated financial statements.  The Company will use the equity method to report the activities as an investment in on its condensed consolidated financial statements.  

Cash and cash equivalents – The Company considers cash and cash equivalents to include all short-term, highly liquid investments that are readily convertible to known amounts of cash and have original maturities of three months or less upon acquisition. Cash and cash equivalents totaled $2,323,599 as of June 30, 2021 and $13,010,356 as of December 31, 2020. 

Short-term investment – The Company classifies investments consisting of a certificate of deposit with a maturity greater than three months but less than one year as short-term investment.  The Company had no short-term investment as of June 30, 2021 or December 31, 2020, respectively.   

Accounts receivable and allowance for credit losses – Accounts receivable are receivables generated from sales to customers and progress billings on performance type contracts. Amounts included in accounts receivable are deemed to be collectible within the Company’s operating cycle. The Company recognizes accounts receivable at invoiced amounts. 

The allowance for credit losses reflects the Company's best estimate of expected losses inherent in the accounts receivable balances. Management provides an allowance for credit losses based on the Company’s historical losses, specific customer circumstances, and general economic conditions. Periodically, management reviews accounts receivable and adjusts the allowance based on current circumstances and charges off uncollectible receivables when all attempts to collect have been exhausted and the prospects for recovery are remote. Recoveries are recognized when they are received. Actual collection losses may differ from our estimates and could be material to our condensed consolidated financial position, results of operations, and cash flows.

3. Summary of Significant Accounting Policies (continued)

Inventory – Raw construction materials (primarily shipping containers and fabrication materials) are valued at the lower of cost (first-in, first-out method) or net realizable value. Finished goods and work-in-process inventories are valued at the lower of cost or net realizable value, using the specific identification method. Medical equipment and COVID-19 test and testing supplies are valued at the lower of cost, (first-in, first-out method) or net realizable value. As of June 30, 2021 there was inventory of $4,429 for construction materials, and $1,405,486 of medical equipment and COVID-19 test and testing supplies. As of December 31, 2020 there was inventory of $4,429 for construction materials, and $773,715 of medical equipment and COVID-19 test and testing supplies. 

Goodwill – The Company performs its impairment test of goodwill at the reporting unit level each fiscal year, or more frequently if events or circumstances change that would more likely than not reduce the fair value of its reporting unit below its carrying values. The Company performs a goodwill impairment test by comparing the fair value of the reporting unit with its carrying value and recognizes an impairment charge for the amount by which the carrying value exceeds the fair value, not to exceed the total amount of goodwill. The amount by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss. There were no impairments during the year ended December 31, 2020 or the six months ended June 30, 2021 and 2020. The Company has taken the recent COVID-19 pandemic into consideration when determining impairment. 

Intangible assets – Intangible assets consist of $2,766,000 of proprietary knowledge and technology, which is being amortized over 20 years. In addition, $97,164 of trademarks, and $47,800 of website costs are being amortized over 5 years.  The Company evaluated intangible assets for impairment during the year ended December 31, 2020, and determined that there were no impairment losses. There was no impairment during the six months ended June 30, 2021 and 2020. The accumulated amortization as of June 30, 2021 and 2020 was $732,085 and $1,686,876, respectively. The amortization expense for the six months ended June 30, 2021 and 2020 was $82,230 and $72,561, respectively. The amortization expense for the three months ended June 30, 2021 and 2020 was $41,823 and $36,281, respectively. The estimated amortization expense for the successive five years is as follows:  

For the year ending December 31,:
2021	$	83,646
2022		162,970
2023		161,176
2024		160,469
2025		157,051
Thereafter		1,453,567
	$	2,178,879

Property, plant and equipment – Property, plant and equipment is stated at cost. Depreciation is computed using the straight-line method over the estimated lives of each asset. Estimated useful lives for significant classes of assets are as follows: computer and software 3 to 5 years, furniture and other equipment 5 to 7 years, automobiles 2 to 5 years, buildings held for lease 5 to 7 years, and equipment 5 to 29 years. Repairs and maintenance are charged to expense when incurred.

Convertible instruments – The Company bifurcates conversion options from their host instruments and accounts for them as free standing derivative financial instruments according to certain criteria. The criteria include circumstances in which (a) the economic characteristics and risks of the embedded derivative instrument are not clearly and closely related to the economic characteristics and risks of the host contract, (b) the hybrid instrument that embodies both the embedded derivative instrument and the host contract is not re-measured at fair value under otherwise applicable generally accepted accounting principles with changes in fair value reported in earnings as they occur and (c) a separate instrument with the same terms as the embedded derivative instrument would be considered a derivative instrument.

Common stock purchase warrants and other derivative financial instruments – The Company classifies as equity any contracts that (i) require physical settlement or net-share settlement or (ii) provides a choice of net-cash settlement or settlement in the Company’s own shares (physical settlement or net-share settlement) providing that such contracts are indexed to the Company’s own stock. The Company classifies as assets or liabilities any contracts that (i) require net-cash settlement (including a requirement to net cash settle the contract if any event occurs and if that event is outside the Company’s control) or (ii) gives the counterparty a choice of net-cash settlement or settlement shares (physical settlement or net-cash settlement). The Company assesses classification of common stock purchase warrants and other free standing derivatives at each reporting date to determine whether a change in classification between assets and liabilities or equity is required.

Fair value measurements – Financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities are carried at cost, which the Company believes approximates fair value due to the short-term nature of these instruments.

The Company measures the fair value of financial assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value.

The Company uses three levels of inputs that may be used to measure fair value:

Level 1	Quoted prices in active markets for identical assets or liabilities.
Level 2	Quoted prices for similar assets and liabilities in active markets or inputs that are observable.
Level 3	Inputs that are unobservable (for example, cash flow modeling inputs based on assumptions).

Transfer into and transfers out of the hierarchy levels are recognized as if they had taken place at the end of the reporting period. 

Share-based payments – The Company measures the cost of services received in exchange for an award of equity instruments based on the fair value of the award. For employees and directors, including non-employee directors, the fair value of a stock option award is measured on the grant date. The fair value amount is then recognized over the period services are required to be provided in exchange for the award, usually the vesting period. The Company recognizes stock-based compensation expense on a graded-vesting basis over the requisite service period for each separately vesting tranche of each award. Stock-based compensation expense to employees and all directors are reported within payroll and related expenses in the consolidated statements of operations. Stock-based compensation expense to non-employees is reported within marketing and business development expense in the condensed consolidated statements of operations.   

Income taxes – The Company accounts for income taxes utilizing the asset and liability approach. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes generally represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from the differences between the financial and tax bases of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted.

The calculation of tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company recognizes liabilities for anticipated tax audit issues based on the Company’s estimate of whether, and the extent to which, additional taxes will be due. If payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when the liabilities are no longer determined to be necessary. If the estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result.

3. Summary of Significant Accounting Policies (continued)

Concentrations of credit risk – Financial instruments, that potentially subject the Company to concentration of credit risk, consist principally of cash and cash equivalents. The Company places its cash with high credit quality institutions. At times, such amounts may be in excess of the FDIC insurance limits. The Company has not experienced any losses in such account and believes that it is not exposed to any significant credit risk on the account.

With respect to receivables, concentrations of credit risk are limited to a few customers in the construction industry. The Company performs ongoing credit evaluations of its customers’ financial condition and, generally, requires no collateral from its customers other than normal lien rights. At June 30, 2021 and December 31, 2020, 62% and 79%, respectively, of the Company’s gross accounts receivable in excess of 10% were due from two and three customers. 

Revenue in excess of 10% relating to one and two customers represented approximately 77% and 72% of the Company's total revenue for the three months ended June 30, 2021 and 2020, respectively. Revenue relating to one and three customers represented approximately 71% and 69% of the Company's total revenue for the six months ended June 30, 2021 and 2020, respectively.

Cost of revenue in excess of 10% relating to three and two vendors represented approximately 52% and 51% of the Company’s total cost of revenue for the three months ended June 30, 2021 and 2020, respectively. Cost of revenue relating to three and four vendors represented approximately 48% and 75% of the Company’s total cost of revenue for the six months ended June 30, 2021 and 2020, respectively. The Company believes it has access to alternative suppliers, with limited disruption to the business, should circumstances change with its existing suppliers.

4. Accounts Receivable

At June 30, 2021 and December 31, 2020, the Company’s accounts receivable consisted of the following:

Receivables are evaluated for collectability and allowances for potential losses are established or maintained on applicable receivables. The allowance for credit losses was $957,116 as of June 30, 2021. There was a provision of $161,202 for credit losses, no recoveries collected for credit losses and no write offs during the six months ended June 30, 2021.

Contract liabilities		(789,068	)		(1,774,740	)
Net contract assets (liabilities)	$	1,333,163		$	(471,604	)

Although management believes it has established adequate procedures for estimating costs to complete on open contracts, it is at least reasonably possible that additional significant costs could occur on contracts prior to completion. The Company periodically evaluates and revises its estimates and makes adjustments when they are considered necessary.

The initial contingent consideration liability of $0 was based on the fair value of the contingent consideration liability at the acquisition date, and is payable in cash and shares of restricted common stock of the Company. Any contingent liability would be paid out in the period after the earn out period, once additional advances are paid in full. As of June 30, 2021, the liability is $0, and no payment has been paid out.

10. Leases

The Company leases an office, a manufacturing plant and certain equipment under non-cancelable operating lease agreements. The leases have remaining lease terms of two and a half years to five years.

10. Leases (continued)

As the leases do not provide an implicit rate, the Company used an incremental borrowing rate based on the information available at the lease commencement date in determining the present value of the lease payments, which is reflective of the specific term of the leases and economic environment of each geographic region.  

Anticipated future lease costs, which are based in part on certain assumptions to approximate minimum annual rental commitments under non-cancelable leases, are as follows: 

Year Ending December 31,		Operating		Financing		Total
2021	$	226,806	$	10,080	$	236,886
2022		401,622		20,160		421,782
2023		330,300		11,760		342,060
2024		324,000		—		324,000
2025		243,000		—		243,000
Total lease payments		1,525,728		42,000		1,567,728
Less: Imputed interest		88,554		1,334		89,888
Present value of lease liabilities	$	1,437,174	$	40,666	$	1,477,840

Chicago Airport Testing has subleased its leased vacant area for a period of one year, the licensee has the option to terminate at any time after the first six months. The licensee elected to terminate the Agreement, subsequent to June 30, 2021.  The effective date of the termination is July 31, 2021 and the Company has $160,000 for the remaining lease revenue.   

11. Net Income (Loss) Per Share

Basic net income (loss) per share is computed by dividing the net income (loss) for the period by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by dividing the net income (loss) for the period by the weighted average number of common and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares consist of the common shares issuable upon the exercise of stock options and warrants. Potentially dilutive common shares are excluded from the calculation if their effect is antidilutive. 

At June 30, 2021, there were options, including options granted to non-employees and non-directors, restricted stock units and warrants to purchase 36,436, 884,344 and 126,890 shares of common stock, respectively, outstanding that could potentially dilute future net income per share. Because the Company had a net loss as of June 30, 2021, it is prohibited from including potential common shares in the computation of diluted per share amounts. Accordingly, the Company has used the same number of shares outstanding to calculate both the basic and diluted loss per share. At June 30, 2020, there were options, including options to non-employees and non-directors, restricted stock units and warrants to purchase 52,337, 44,518 and 353,190 shares of common stock, respectively, outstanding that could potentially dilute future net income per share.

12. Construction Backlog

The following represents the backlog of signed construction and engineering contracts in existence at June 30, 2021 and December 31, 2020, which represents the amount of revenue the Company expects to realize from work to be performed on uncompleted contracts in progress and from contractual agreements in effect at June 30, 2021 and December 31, 2020, respectively, on which work has not yet begun:

Backlog at June 30, 2021 included two contracts entered into during the third quarter of 2020 in the amount of approximately $4 million and approximately $2.95 million along with three contracts during the fourth quarter of 2020 in the amount of approximately $2.7 million, $0.80 million, and $0.70 million. In addition, the Company executed one large contract in the first quarter of 2021 in the amount of approximately $1.3 million. The Company expects that all of this revenue will be realized by June 30, 2023. As previously discussed in Note 3, the ELA was terminated and in connection with the termination a Settlement and Mutual Release Agreement was executed. The Company is receiving an assignment of CPF's right to a $1.25 million redemption distribution for one such project.  The Company does not expect to receive any royalties from the terminated ELA and Backlog does not include the redemption distribution fee. 

The Company’s remaining backlog as of June 30, 2021 represents the remaining transaction price of firm contracts for which work has not been performed and excludes unexercised contract options. 

The Company expects to satisfy its backlog which represents the remaining unsatisfied performance obligation on contracts as of June 30, 2021 over the following period:

	2021
Within 1 year	$	8,179,581
1 to 2 years		12,856,250
Total Backlog	$	21,035,831

Although backlog reflects business that is considered to be firm, cancellations, deferrals or scope adjustments may occur. Backlog is adjusted to reflect any known project cancellations, revisions to project scope and cost and project deferrals, as appropriate.

In the event that there is not an effective registration statement permitting for the resale of the shares underlying the Placement Agent Warrants, the Placement Agent Warrant’s shall be exercisable on a cashless basis. There are significant restrictions pursuant to FINRA Rule 5110 against transferring the Placement Agent’s Warrants and the shares issuable upon exercise of the Placement Agent Warrants during the one hundred eighty (180) days after the closing date. 

On December 10, 2019, the Company and ThinkEquity entered into a waiver agreement (“Waiver of Warrant”) pursuant to which ThinkEquity surrendered its rights to a warrant previously issued to ThinkEquity on November 12, 2019 to purchase 5,404 shares of the Company’s common stock as compensation for acting as placement agent for the private placement of the Debenture. 

For the three and six months ended June 30, 2021, we had 1,200 and 226,300 warrants that converted into common stock and had no warrants that converted into common stock for the three and six months ended June 30, 2020.

Stock-Based Option Awards 

The Company has issued no stock-based options during the six months ended June 30, 2021 and 2020.   

Because the Company does not have significant historical data on employee exercise behavior, the Company uses the “Simplified Method” to calculate the expected life of the stock-based option awards granted to employees. The simplified method is calculated by averaging the vesting period and contractual term of the options.

Legal Proceedings

The Company is subject to certain claims and lawsuits arising in the normal course of business. The Company assesses liabilities and contingencies in connection with outstanding legal proceedings utilizing the latest information available. Where it is probable that the Company will incur a loss and the amount of the loss can be reasonably estimated, the Company records a liability in our consolidated financial statements. These legal accruals may be increased or decreased to reflect any relevant developments on a quarterly basis. Where a loss is not probable or the amount of the loss is not estimable, the Company does not record an accrual, consistent with applicable accounting guidance. Based on information currently available, advice of counsel, and available insurance coverage, the Company believes that the established accruals are adequate and the liabilities arising from the legal proceedings will not have a material adverse effect on the consolidated financial condition. However, that in light of the inherent uncertainty in legal proceedings there can be no assurance that the ultimate resolution of a matter will not exceed established accruals. As a result, the outcome of a particular matter or a combination of matters may be material to the results of operations for a particular period, depending upon the size of the loss or the income for that particular period.

Pizzarotti Litigation - On or about August 10, 2018 Pizzarotti, LLC filed a complaint against the Company and Mahesh Shetty, the Company’s former President and CFO, and others, seeking unspecified damages for an alleged breach of contract by the Company and another entity named Phipps & Co. (“Phipps”). The lawsuit was filed as Pizzarotti, LLC. v. Phipps & Co., et al., Index No. 653996/2018 and commenced in the Supreme Court of the State of New York for the County of New York. On or about April 1, 2019, Phipps filed cross-claims against the Company and Mr. Shetty asserting claims for indemnification, contribution, fraud, negligence, negligent misrepresentation, and breach of contract. SG Blocks has likewise cross claimed against Phipps for indemnification and contribution, claiming that any damages to the Plaintiff were the result of the acts or omissions of Phipps and its principals. Pizzarotti’s suit arose from a contract dated April 3, 2018 that it executed with Phipps whereby Pizzarotti, a construction manager, engaged Phipps to perform stone procuring and tile work at a construction project located at 161 Maiden Lane, New York 10038. Pizzarotti’s claims against the Company arise from a purported assignment agreement dated August 10, 2018, whereby Pizzarotti claims that the Company agreed to assume certain obligations of Phipps under a certain trade contract between Pizzarotti and Phipps & Co. Phipps’ claims against the Company arise from a purported Assignment Agreement, dated as of May 30, 2018, between Pizzarotti, Phipps and the Company (the “Assignment Agreement”), pursuant to which, it is alleged, that the Company agreed to provide a letter of credit in connection with the sub-contracted work to be provided by Phipps to Pizzarotti. The Company believes that the Assignment Agreement was void for lack of consideration and moved to dismiss the case on those and other grounds. On June 17, 2020, the New York Supreme Court entered an order dismissing certain claims against the Company brought by cross claimant Phipps & Co. Specifically, the court dismissed Phipps’ claims for indemnification, contribution, fraud, negligence and negligent misrepresentation. The court did not dismiss Phipps’ claim for breach of the Assignment Agreement. The issue of the validity of the Assignment Agreement, and the Company’s defenses to the claims brought by the plaintiff Pizzarotti, and cross claimant Phipps, are being litigated. The Company maintains that the Assignment Agreement, to the extent valid and enforceable, was properly terminated and/or there are no damages, and, consequently, that the claims brought against the Company are without merit. The Company intends to continue to vigorously defend the litigation. The parties have engaged in written discovery but no depositions have been conducted as of yet. By motion dated February 24, 2021, Pizzarotti moved to stay the entire action pending the outcome of a separate litigation captioned Pizzarotti, LLC v. FPG Maiden Lane, LLC et. al., Index No. 651697/2019, involving some of the same parties (but excluding the Company). Phipps cross moved to consolidate the two actions. The Company opposed both motions. On April 26, 2021, the Court denied both motions and directed the parties to meet and confer concerning the scheduling of depositions. On May 10, 2021, the parties jointly filed with the Court a proposed order providing the completion of depositions of all parties and nonparties by September 30, 2021. The parties are currently in the process of scheduling depositions for the latter part of September.

Litigation is subject to many uncertainties, and the outcome of this action is not predicted with assurance. The Company is currently unable to predict the possible loss or range of loss, if any, associated with the resolution of this litigation, and, accordingly, the Company has made no provision related to this matter in the condensed consolidated financial statements.

1.Shetty v. SG Blocks, Inc. et. al., Case No. 20-CV-00550, United States District Court, Eastern District of New York. On January 31, 2020, Mahesh Shetty, the Company’s former President and Chief Financial Officer (“Former Employee”), filed suit against the Company and its Chairman and Chief Executive Officer, Paul Galvin, claiming (i) $372,638 in unpaid wages and bonuses and (ii) $300,000 due in severance (hereafter the “Action”).

The Company asserted that the Former Employee agreed to accept (and did receive) restricted stock units of the Company’s common stock in full satisfaction and payment of all alleged unpaid wages and bonuses that are claimed in the Action, and/or has otherwise been paid in full for all amounts claimed. The Company further maintained that the Former Employee’s employment agreement precludes any entitlement to or liability for severance. On June 15, 2020, the Court entered a decision granting in part and denying in part the Company’s motion to dismiss. Specifically, the Court dismissed the Former Employee’s claim (i) for severance (in the amount of $300,000) and unpaid wages pursuant to the FLSA, but denied dismissal of the Former Employee’s claims for retaliation under the FLSA or unpaid wages allegedly due under the New York Labor Law.

On or about August 6, 2021, the Company and Former Employee reached an agreement in principle to settle the Action. The parties, through their respective counsel, are currently negotiating the terms of a written settlement and release agreement which has yet to be finalized or executed.

Litigation is subject to many uncertainties, and the outcome of this action is not predicted with assurance. Although the Company expects that the Action will be dismissed upon the execution of a settlement and release agreement, failing same the Company is unable to predict the outcome or possible recovery or loss or range of loss, if any, associated with the resolution of this litigation, and, accordingly, the Company has made no provision related to this matter in the condensed consolidated financial statements

Overview

Using our proprietary technology and design and engineering expertise, we modify code-engineered cargo shipping containers and purpose-built modules for use for safe and sustainable commercial, industrial and residential building construction. Rather than consuming new steel and lumber, our proprietary technology and design and engineering expertise allows for the redesign, repurpose and conversion of heavy-gauge steel cargo shipping containers into SGBlocks™, which are safe green building blocks for commercial, industrial, and residential building construction.

Our business model originally was a project-based construction model pursuant to which we were responsible for the design, construction and sale of finished products that incorporated our technology to customers throughout the United States primarily in the multi-family housing, restaurant, military and education industries. From October 2019 to June 2021, our business model for residential building construction became a royalty-fee model established under a five-year exclusive license with CPF MF 2019-1 LLC (“CPF”) pursuant to which CPF received an exclusive license for our proprietary technology for residential use, including, without limitation, single-family residences and multi-family residences, but specifically excluding military housing. Our Ridge Avenue Project, a residential housing project in Atlanta, was also excluded from the license to CPF.  In June 2021, we terminated the license to CPF and recommenced our original project-based business model pursuant to which we design, construct and sell finished products to customers throughout the United States.

In April 2020, we expanded our product offerings and began focusing on the medical projects when we entered into the COVID-19 diagnostic market through the distribution of COVID-19 diagnostic tests.  We have subsequently entered into additional collaborations for the distribution of diagnostic tests as well as collaborations for the use of our modular technology for the building of medical test centers that include COVID-19 testing. During 2020, we entered into a joint venture, and have begun, to provide clinical lab testing, as well as test kit sales related to a separate distributer agreement. In addition, in January 2021, we together with other third parties formed Chicago Airport Testing LLC (“CAT”). CAT, is in the business of marketing, selling, distributing leasing and otherwise commercially exploiting certain products and services in the medical industry, including COVID-19 testing. 

In September 2020, we acquired substantially all the assets of Echo, a Texas limited liability company, except for Echo's real estate holdings for which we obtained a right of first refusal, which we subsequently exercised on February 24, 2021. Echo is a container/modular manufacturer based in Durant, Oklahoma specializing in the design and construction of permanent modular and temporary modular buildings and was one of our key supply chain partners. Echo catered to the military, education, administration facilities, healthcare, government, commercial and residential customers. This acquisition has allowed us to expand our reach for our Modules and offers us an opportunity to vertically integrate a large portion of our cost of goods sold, as well as increase margins, productivity and efficiency in the areas of design, estimating, manufacturing and delivery. We decided not to pursue the option to acquire Echo's real estate holdings in the second quarter of 2021.   

Recent Business Developments 

On May 10, 2021, we acquired a 50+ acre site in Lago Vista, Texas (the “Lago Vista Site”) for $3,500,000, paid in cash, pursuant to an Unimproved Property Contract, dated February 25, 2021, with Northport Harbor LLC. The acquired parcel sits on Lake Travis on the Colorado River in central Texas and we plan to build upscale condominiums, a health club, marina and other amenities. Our current plan is to develop 277,000 square feet at the Lago Vista site and build 225 units on the Lago Vista Site with the first units estimated to be delivered in the second and third quarter of 2022 and completion of all units estimated to be fourth quarter of 2022, subject to adequate supply chain and personnel.

On May 31, 2021, our subsidiary SGB Development Corp. (“SG DevCorp”), acquired a 50% membership interest in a limited liability company that is building affordable housing in the Atlanta, Georgia metropolitan area to be known as “Norman Berry Village”. SGB DevCorp has partnered with CMC, a New York City-based real estate development firm with national expertise, with ZT Architecture & Land Development and Community Development Consortium providing design build services. CMC has previously engaged SG Blocks to complete a design build project known as Ridge Avenue, also in Atlanta. We expect the project to develop 125,000 square feet and build 138 units at Norman Berry Village with the first units estimated to be delivered in the second quarter of 2022 and completion of all units estimated to be fourth quarter of 2022, subject to adequate supply chain and personnel. 

On June 15, 2021, we terminated the Exclusive License Agreement with CPF that we had entered into on October 3, 2019.  In connection with the termination we  entered into a Settlement and Mutual Release Agreement (the “Settlement Agreement”) with CPF, the general partner (the “Licensee”) of CPF MF 2019-1 LLC (“CPF MF”), and Capital Plus Financial, LLC, a limited partner of the Licensee (“Capital Plus”) and an Assignment of Limited Rights Under Membership Interest Redemption Agreement, dated June 15, 2021, with Capital Plus and the Licensee in connection with the termination of that certain Exclusive License Agreement, dated as of October 3, 2019 (the “License Agreement”), with the Licensee Pursuant to the Settlement Agreement with CPF and Capital Plus, the License Agreement was terminated, we released CPF and CPF MF for any claims in exchange for releases from CPF and Capital Plus and we receiving an assignment of CPF’s right under certain circumstances to a $1.25 million redemption distribution from CPF MF under its Operating Agreement. 

On June 24, 2021, SG DevCorp, as member, entered into an Operating Agreement, with Jacoby Development, Inc., a Georgia corporation (“JDI”), as manager, dated June 24, 2021 (the “Operating Agreement”), for JDI-Cumberland Inlet, LLC, a Georgia limited liability company (“JDI-Cumberland”), pursuant to which SG DevCorp acquired a 10% non-dilutable equity interest (“LLC Interest”) in JDI-Cumberland and contributed $3,000,000 in capital for the development of a 1,286 acre waterfront parcel in downtown historic St. Marys, Georgia (the “Project”). SG DevCorp in conjunction with Jacoby Development of Atlanta, Georgia expects to develop a mixed-use destination community. The 1,286-acre waterfront parcel of land closed on June 30, 2021. We expect that JDI-Cumberland Inlet, LLC will build 1,280 units of approximately 1,000 square feet per home for this Project with the first units estimated to be delivered in the third quarter of 2022 and completion of all units estimated to be completed over a three year period, subject to adequate supply chain and personnel.

The Operating Agreement provides JDI with the right, at its option, to purchase the LLC Interest from SG DevCorp on or before June 24, 2023 for $3,000,000, plus an amount equal to an annual internal rate of return (IRR) on such funds of forty (40%) percent (i.e., $1,200,000 annualized). After June 24, 2023, the Operating Agreement provides JDI with the right, at its option, to purchase the LLC Interest from SG DevCorp for $3,000,000, plus an amount equal to an IRR of thirty-two and one-half (32.5%) percent (i.e., $975,000 annualized). The Operating Agreement also provides that if JDI receives a good faith, bona fide written offer from an unaffiliated third party to purchase all or any portion of the Project, JDI shall first offer the Project to SG DevCorp at the same price and upon substantially the same terms as are contained in the third party offer.

In connection with our  acquisition of the LLC Interest, our subsidiary, SG Echo, LLC (“SG Echo”), entered into a Fabrication and Building Services Agreement (“Building Services Agreement”) with JDI-Cumberland to design, fabricate and install various improvements for the Project using modular structures, pursuant to budgets prepared by SG Echo submitted for approval to JDI-Cumberland, including a marina, town center, apartments and single family units, townhomes, commercial, retail and lodging buildings/structures, eco-tourism park, camping yurts, cabins and cottages,. The Building Services Agreement has an initial term of three years, with two-year automatic renewal provisions. 

On July 14, 2021, SG DevCorp entered into a Real Estate Lien Note, dated July 14, 2021, in the principal amount of $2,000,000 (the “Note”), secured by a Deed of Trust, dated July 14, 2021, on its 50+ acre Lake Travis project site in Lago Vista, Texas and a related Assignment of Leases and Rents, dated July 8, 2021, for net loan proceeds of $1,958,233 after fees. The Note has a term of one (1) year, provides for payments of interest only at a rate of twelve percent (12%) per annum and may be prepaid without penalty commencing nine (9) months after its issuance date. If the Note is prepaid prior to nine (9) months after its issuance date, a 0.5% prepayment penalty is due. SG DevCorp intends to use the proceeds of the Note for its development projects.

Results of Operations

Our operations for the six months ended June 30, 2021 and 2020 may not be indicative of our future operations. Our operations for the three and six months ended June 30,2021 includes the operations of SG Echo which was acquired in September 2020, Clarity Mobile Venture and Chicago Airport Testing and accordingly the operations for the three and six months ended June 30, 2020 do not include any revenue or costs associated with SG Echo, Clarity Mobile Venture and Chicago Airport Testing.  

Impact of Coronavirus (COVID-19)

             With the global spread of the ongoing novel coronavirus ("COVID-19") pandemic during 2020, we have implemented business continuity plans designed to address and mitigate the impact of the COVID-19 pandemic on its employees and business. The worldwide spread of the COVID-19 virus has resulted in, and may continue to result in, a global slowdown of certain economic activity which is likely to decrease demand for a broad variety of goods and services, including from our customers, while also resulting in delays in projects due to labor shortages and supplier disruptions for an unknown period of time until the disease is contained.  To date, we have experienced some delays and increased costs for materials, especially lumber, in projects due to COVID-19 which we expect to continue to have an impact on our revenue and our results of operations, the size and duration of which we are currently unable to predict. Any quarantines, the timing and length of containment and eradication solutions, travel restrictions, absenteeism by infected workers, labor shortages or other disruptions to the suppliers and contract manufacturers or customers would likely adversely impact our sales, and operating results and result in further project delays. In addition, the pandemic could result in an economic downturn that could affect the ability of our customers and licensees to obtain financing and therefore impact demand for our products. Order lead times could be extended or delayed and increases we have experienced in pricing could continue to increase. Some products or services may become unavailable if the regional or global spread were significant enough to prevent alternative sourcing. Accordingly, we are considering alternative product sourcing in the event that product supply becomes problematic. We expect this global pandemic to have an impact on the Company's revenue and results of operations, the size and duration of which we are currently unable to predict. In addition, to the extent the ongoing COVID-19 pandemic adversely affects our business and results of operations, it may also have the effect of heightening many of the other risks and uncertainties which we face.

Revenue 

During the six months ended June 30, 2021, we derived revenue from the following three categories of sources: construction services, engineering services and medical revenue.  The medical revenue source was a new source and we commenced receipt of revenue from this source in the fourth quarter of 2020 when Clarity Mobile Venture LLC commenced operations and we continued to derive revenue from this source during the quarter ended June 30, 2021 with strong revenue related to COVID-19 samples collected from our Clarity Mobile joint venture in the first six months of 2021. Total revenue for the six months ended June 30, 2021 was $21,041,614 compared to $827,705 for the six months ended June 30, 2020. This increase of $20,213,909 or approximately 2442% was mainly driven by an increase in medical revenue of approximately $15,740,000 (lab testing, test kit sales and equipment but excluding revenue generated from construction of medical related projects) from mainly the collection of COVID-19 test samples with additional medical revenue from the opening and subletting of a testing facility in the Chicago area, an increase in revenue of approximately $1,665,000 in special use projects which includes one legacy contract commitment related to the SG Echo acquisition, an increase in revenue of approximately $2,180,000 in government projects, an increase in revenue of approximately of $435,000 in medical related construction projects and a moderate increase in construction revenue related to office and hotel/hospitality projects for approximately $385,000 and $410,000, respectively, offset by a decrease in revenue related to our retail and other projects for approximately $275,000 and $300,000, respectively, for the six months ended June 30, 2021, as compared to June 30, 2020. 

36

Cost of Revenue and Gross Profit 

Cost of revenue was $16,994,389 for the six months ended June 30, 2021, compared to $407,491 for the six months ended June 30, 2020. The increase of $16,586,898 or a increase of approximately 4070%, is primarily related to higher testing volumes which required an increase in procurement of COVID-19 tests and testing supplies and higher procurement and manufacturing costs of modifying containers and wood modular units. Due to capabilities of Echo, we have now increased our sales of wood modular units to our customer base. As previously stated our costs of revenue for the six months ended June 30, 2021 include costs and expenses associated with the operations of SG Echo, Clarity Mobile Venture and Chicago Airport Testing and our costs of revenue for the six months ended June 30, 2020 do not include such costs or expenses. 

Gross profit was $4,047,225 and $420,214 for the six months ended June 30, 2021 and 2020, respectively.   

Gross profit margin percentage decreased to approximately 19% for the six months ended June 30, 2021 compared to approximately 51% for the six months ended June 30, 2020.  The decrease in gross profit margin percentage was primarily due to a non-recurring single legacy contract recognized in 2020 in the amount of $300,000 with no estimated costs and due to legacy contract commitments from the acquisition of SG Echo that were recognized in the six months ended June 30, 2021 that incurred losses of approximately $2,400,000 due to escalations in material pricing related to COVID-19 and labor overages.

Payroll and Related Expenses

Payroll and related expenses for the six months ended June 30, 2021 were $1,629,186 compared to $664,146 for the six months ended June 30, 2020. This increase was primarily caused by an increase in salaries and additional head count hired to help manage the growth of SG Echo and other recently launched subsidiaries such as Chicago Airport Testing, Clarity Mobile Venture, and SGB Development Corp. of approximately $543,000 and an increase of approximately $420,000 in stock-based compensation expense, recognized for the six months ended June 30, 2021 compared to the six months ended June 30, 2020. We recognized $532,422 in stock-based compensation expense related to payroll and related expenses for the six months ended June 30, 2021, compared to $111,394  for June 30, 2020.

37

Other Operating Expenses (General and administrative expenses, Marketing and business development expense, and Pre-project expenses)

Other operating expenses (general and administrative expenses, marketing and business development expenses, pre-project expenses) for the six months ended June 30, 2021 were $3,503,563 compared to $1,346,301 for the six months ended June 30, 2020. The increase resulted primarily from an increase in rent expense of approximately $100,000 related to COVID-19 cold storage charges and rental expense for the Chicago Airport Testing facility, an increase in public expenses  of approximately $109,000, an increase in information technology expense of approximately $113,000, an increase in insurance expense of approximately $99,000 for additional insurance coverage for COVID-19 medical operations, an increase in contract labor expense of approximately $466,000 with the majority related to the start-up and ongoing operations of the COVID-19 medical projects.  The Company had an increase of approximately $458,000 in laboratory medical expenses mainly from the start-up and continued operations in Wayne County, Michigan and LAX COVID-19 testing locations, an increase of  approximately $352,000 for manager’s oversight fees related to Clarity Mobile Venture, an increase in depreciation expense of approximately $114,000, an increase in travel expense by approximately $68,000, an increase in bad debt expense of approximately $161,000 due from one legacy customer from the acquisition of SG Echo with a slight decrease in legal fees of approximately $109,000. We recognized no stock-based compensation expense related to legal expense and marketing expense for the six months ended June 30, 2021 and $57,120 for the six months ended June 30, 2020.  

Other Income (Expense)

Interest income for the six months ended June 30, 2021 was $31,267 mainly derived from bank interest and interest associated with an outstanding note receivable. There was $11,096 of interest income for the six months ended June 30, 2020. Other income for the six months ended June 30, 2021 was $61,024 related to miscellaneous income. There was no other income for the six months ended June 30, 2020. Interest expense for the six months ended June 30 2021 and 2020 was $692 and $6,263, respectively.

Income Tax Provision

A 100% valuation allowance was provided against the deferred tax asset consisting of available net operating loss carry forwards and, accordingly, no income tax benefit was provided. 

Impact of Inflation

The impact of inflation upon the Company’s revenue and income (loss) from continuing operations during each of the past two fiscal years has not been material to its financial position or results of operations for those years because the Company does not maintain any inventories whose costs are affected by inflation.

Revenue

During the three months ended June 30, 2021, we derived revenue from the following three categories of sources: construction services, engineering services and medical revenue.  The medical revenue source was a new source and we commenced receipt of revenue from this source in the fourth quarter of 2020 when Clarity Mobile Venture LLC commenced operations and we continued to derive revenue from this source during the quarter ended June 30, 2021 with strong revenue related to COVID-19 samples collected from our Clarity Mobile joint venture in the three months ended June 30, 2021. Total revenue for the three months ended June 30, 2021 was $11,853,987 compared to $628,949 for the three months ended June 30, 2020. This increase of $11,225,038 or approximately 1785% was mainly driven by an increase in medical revenue of approximately $9,785,000 (lab testing, test kit sales and equipment but excluding revenue generated from construction of medical related projects) from mainly the collection of COVID-19 test samples with additional medical revenue from the opening and subletting of a testing facility in the Chicago area, an increase in revenue of approximately $206,000 in special use projects which includes one legacy contract commitment related to the SG Echo acquisition, an increase in revenue of approximately $1,097,000 in government projects, an increase in revenue of approximately of $185,000 in medical related construction projects and a moderate increase in construction revenue related to office and hotel/hospitality projects for approximately $248,000 and $245,000, respectively, offset by a decrease in revenue related to our retail and other projects for approximately $199,000 and $300,000, respectively, for the six months ended June 30, 2021, as compared to June 30, 2020.  

Cost of Revenue and Gross Profit

Cost of revenue was $9,014,943 for the three months ended June 30, 2021, compared to $254,716 for the three months ended June 30, 2020. The increase of $8,760,227 or an increase of approximately 3439%, is primarily related to higher testing volumes which required an increase in procurement of COVID-19 tests and testing supplies and higher procurement and manufacturing costs of modifying containers and wood modular units.  

Gross profit was $2,839,044 and $374,233 for the three months ended June 30, 2021 and 2020, respectively.  

Gross profit percentage decreased to approximately 24% for the three months ended June 30, 2021 compared to approximately 60% for the three months ended June 30, 2020.  The decrease in gross profit margin percentage was primarily due to a non-recurring single legacy contract recognized in 2020 in the amount of $300,000 with no estimated costs and due to four legacy contract commitments from the acquisition of SG Echo that were recognized in 2021 that incurred losses of approximately $1,200,000 due to escalations in material pricing related to COVID-19 and labor overages 

Payroll and Related Expenses

Payroll and related expenses for the three months ended June 30, 2021 were $801,664 compared to $392,338 for the three months ended June 30, 2020. This increase was primarily caused by an increase in salaries and additional head count to help manage the growth of SG Echo and other recently launched subsidiaries such as Chicago Airport Testing, Clarity Mobile Ventures, and SGB Development Corp. of approximately $253,000 and an increase of approximately $173,500 in stock-based compensation expense, recognized for the three months ended June 30, 2021 compared to the three months ended June 30, 2020. We recognized $246,236 in stock-based compensation expense related to payroll and related expenses for the three months ended June 30, 2021, compared to $72,630 for June 30, 2020.

Results of Operations (continued) 

Other Operating Expenses (General and administrative expenses, Marketing and business development expense, and Pre-project expenses)

Other operating expenses (general and administrative expenses, marketing and business development expenses, pre-project expenses) for the three months ended June 30, 2021 were $1,961,447 compared to $822,649 for the three months ended June 30, 2020. The increase resulted primarily from an increase in rent expense of approximately $48,000 related to COVID-19 cold storage charges and rental expense for the Chicago Airport Testing facility, an increase in public expenses of approximately $93,000, an increase in information technology expense of approximately $50,000, an increase in insurance expense of approximately $81,000 for additional insurance coverage for COVID-19 medical operations, an increase in contract labor expense of approximately $281,000 with the majority related to the start-up and ongoing operations of the COVID-19 medical projects.  The Company had an increase of approximately $76,000 in laboratory medical expenses mainly from the start-up and continued operations in Wayne County, Michigan and LAX COVID-19 testing locations, an increase of approximately $321,000 for manager’s oversight fees related to Clarity Mobile Venture, an increase in depreciation expense of approximately $64,000, an increase in travel expense by approximately $34,500, an increase in bad debt expense of $161,000 due from one legacy customer from the acquisition of SG Echo with a slight decrease in legal fees of $125,000. We recognized no stock-based compensation expense related to legal expense and marketing expense for the three months ended June 30, 2021 and $57,120 for the three months ended June 30, 2020.

Other Income (Expense)

Interest income for the three months ended June 30, 2021 and 2020 was $13,797 and $6,233 mainly derived from bank interest and interest associated with an outstanding note receivable. Interest expense for the three months ended June 30, 2021 and 2020 was $329 and $3,452 and mainly related to the Securities Purchase Agreement entered into on February 4, 2020 with an accredited investor. Other income for the three months ended June 30, 2021 was $61,024 related to miscellaneous income. There was no other income for the three months ended June 30, 2020. 

Liquidity and Capital Resources

As of June 30, 2021 and December 31, 2020, we had an aggregate of $2,323,599 and $13,010,356, respectively, of cash and cash equivalents. 

On February 4, 2020, we entered into a Securities Purchase Agreement with an accredited investor, pursuant to which we issued to the investor a secured note in the aggregate principal amount of $200,000 (the “Note”), which bore interest at a rate of nine percent (9%) per annum and was due on July 31, 2023, and was secured by a security interest in the royalty payable to us under that certain Exclusive License Agreement, dated October 3, 2019, with CPF GP 2019-1 LLC. During the third quarter of 2020, the Note to investor of $200,000 and unpaid accrued interest of $6,263 was converted into 73,665 shares of common stock. 

40

In April 2020, we completed a public offering where we pursuant to which we sold 440,000 shares of common stock at a public offering price of $4.25 per share which resulted in net proceeds of approximately $1,522,339 after deducting underwriting discounts and commissions and other expenses related to the offering. 

In May 2020, we completed a public offering pursuant to which we sold an aggregate of 6,900,000 shares of common stock at a public offering price of $2.50 per share which resulted in net proceeds of approximately $15,596,141 after deducting underwriting discounts and commissions and other expenses related to the offering.  

We anticipate that we will continue to generate losses from operations until the fourth quarter of 2021. At June 30, 2021 and December 31, 2020 we had a cash balance of $2,323,599 and $13,010,356, respectively. As of June 30, 2021, our stockholders’ equity was $16,840,723, compared to $18,437,823 as of December 31, 2020. Our net loss for the six months ended June 30, 2021 was $993,925 and net cash used in operating activities was $1,307,944. We anticipate our cash balance is sufficient to last at least twelve months from August 13, 2021.

We may need to generate additional revenues or secure additional financing sources, such as debt or equity capital, to fund future growth, which financing may not be available on favorable terms or at all. We do not have any additional sources secured for future funding, and if we are unable to raise the necessary capital at the times we require such funding, we may need to materially change our business plan, including delaying implementation of aspects of such business plan or curtailing or abandoning such business plan altogether.

Operating activities used net cash of $1,307,944 during the six months ended June 30, 2021, and $2,181,122 during the six months ended June 30, 2020. Generally, our net operating cash flows fluctuate primarily based on changes in our profitability and working capital. Cash used in operating activities decreased by approximately $873,178 primarily due to an decrease in working capital of approximately $442,000, an increase of approximately $364,000 in stock-based compensation, an increase of approximately $196,500 in depreciation expense, an increase of approximately $161,000 in bad debt expense and a decrease in the overall net loss of approximately $591,000, in the six months ended June 30, 2021 compared to the six months ended June 30, 2020. 

Investing activities used net cash of $8,243,216 during the six months ended June 30, 2021, and $650,000 during the six months ended June 30, 2020. Cash used in investing activities increase from the corresponding period of the prior year primarily due to the purchase of property, plant and equipment of approximately $4,692,000 which included the land purchase for the Austin project totaling approximately $3,575,000, purchase of intangible assets of $42,500, payments on assumed liabilities related to the Echo DCL, LLC acquisition of approximately $157,500, and investments in two SGB Development entities totaling approximately $3,350,000.  

Financing activities used net cash of $1,135,597 during the six months ended June 30, 2021, and provided net cash of $17,318,358 during the six months ended June 30, 2020.  Cash provided by financing activities decreased by approximately $17,318,000 due to a decrease in proceeds from public stock offerings and proceeds from long-term note payable in the six months ended June 30, 2021. Cash used by financing activities for the six months ended June 30, 2021 increased by approximately $1,842,784 due to distributions paid to our non-controlling interest partner, offset by an increase of approximately $707,000 in proceeds from conversion of outstanding warrants to common stock.

We provide services to our construction and engineering customers in three separate phases: the design phase, the architectural and engineering phase and the construction phase. Each phase is independent of the other, but builds through a progression of concept through delivery of a completed structure. These phases may be embodied in a single contract or in separate contracts, which is typical of a design build process model. As of June 30, 2021, we had 14 projects totaling $21,035,831 under contract, which, if they all proceed to construction, will result in our constructing approximately 224,026 square feet of container and modular space. Of these contracts, all fourteen projects combine all three phases or parts thereof and including construction. We expect that all of this revenue will be realized by June 30, 2023.

Backlog may fluctuate significantly due to the timing of orders or awards for large projects and is not necessarily indicative of future backlog levels or the rate at which backlog will be recognized as revenue. The decrease in backlog of approximately $4,081,000 from December 31, 2020 is primarily attributable to one new contract we entered into during the first quarter of 2021 for approximately $1,325,000 and offset by work in progress or completed contracts during the first six months of 2021 for approximately $5,328,000.

There can be no assurance that our customers will decide to and/or be able to proceed with these construction projects, or that we will ultimately recognize revenue from these projects in a timely manner or at all.

Off-Balance Sheet Arrangements

As of June 30, 2021 and December 31, 2020, we had no material off-balance sheet arrangements to which we are a party.

In the ordinary course of business, we enter into agreements with third parties that include indemnification provisions which, in our judgment, are normal and customary for companies in our industry sector. These agreements are typically with consultants and certain vendors. Pursuant to these agreements, we generally agree to indemnify, hold harmless, and reimburse indemnified parties for losses suffered or incurred by the indemnified parties with respect to actions taken or omitted by us. The maximum potential amount of future payments we could be required to make under these indemnification provisions is unlimited. We have not incurred material costs to defend lawsuits or settle claims related to these indemnification provisions. As a result, the estimated fair value of liabilities relating to these provisions is minimal. Accordingly, we have no liabilities recorded for these provisions as of June 30, 2021.

Critical Accounting Policies and New Accounting Pronouncements

Critical Accounting Policies

Our condensed consolidated financial statements have been prepared using generally accepted accounting principles in the United States of America (“GAAP”). In connection with the preparation of the financial statements, we are required to make assumptions and estimates and apply judgments that affect the reported amounts of assets, liabilities, revenue, and expenses, and the related disclosures. We base our assumptions, estimates, and judgments on historical experience, current trends, and other factors that we believe to be relevant at the time the consolidated financial statements are prepared. On a regular basis, we review the accounting policies, assumptions, estimates, and judgments to ensure that our financial statements are presented fairly and in accordance with GAAP. However, because future events and their effects cannot be determined with certainty, actual results could differ from our assumptions and estimates, and such differences could be material.

Our significant accounting policies are discussed in “Note 3— Summary of Significant Accounting Policies” of the notes to our condensed consolidated financial statements included elsewhere in this report. We believe that the following accounting policies are the most critical in fully understanding and evaluating our reported financial results.

Share-based payments. We measure the cost of services received in exchange for an award of equity instruments based on the fair value of the award. For employees and directors, including non-employee directors, the fair value of the award is measured on the grant date. For non-employees, the fair value of the award is generally re-measured on interim financial reporting dates and vesting dates until the service period is complete. The fair value amount is then recognized over the period services are required to be provided in exchange for the award, usually the vesting period. We recognize stock-based compensation expense on a graded-vesting basis over the requisite service period for each separately vesting tranche of each award. Stock-based compensation expense to employees and all directors is reported within payroll and related expenses in the consolidated statements of operations. Stock-based compensation expense to non-employees is reported within marketing and business development expense in the consolidated statements of operations. 

Other derivative financial instruments. SGB classifies as equity any contracts that (i) require physical settlement or net-share settlement or (ii) provide a choice of net-cash settlement or settlement in SGB’s own shares (physical settlement or net-share settlement), provided that such contracts are indexed to SGB’s own stock. SGB classifies as assets or liabilities any contracts that (i) require net-cash settlement (including a requirement to net-cash settle the contract if any event occurs and if that event is outside SGB’s control) or (ii) give the counterparty a choice of net-cash settlement or settlement shares (physical settlement or net-cash settlement). SGB assesses classification of common stock purchase warrants and other free-standing derivatives at each reporting date to determine whether a change in classification between assets and liabilities or equity is required.

43

Critical Accounting Policies (continued)

Convertible instruments. SGB bifurcates conversion options from their host instruments and accounts for them as free-standing derivative financial instruments according to certain criteria. The criteria include circumstances in which (i) the economic characteristics and risks of the embedded derivative instrument are not clearly and closely related to the economic characteristics and risks of the host contract; (ii) the hybrid instrument that embodies both the embedded derivative instrument and the host contract is not re-measured at fair value under otherwise applicable GAAP measures with changes in fair value reported in earnings as they occur; and (iii) a separate instrument with the same terms as the embedded derivative instrument would be considered a derivative instrument.

SGB determined that the embedded conversion options that were included in the previously outstanding convertible debentures should be bifurcated from their host and a portion of the proceeds received upon the issuance of the hybrid contract has been allocated to the fair value of the derivative. The derivative was subsequently marked to market at each reporting date based on current fair value, with the changes in fair value reported in results of operations. 

Revenue recognition – we determine, at contract inception, whether it will transfer control of a promised good or service over time or at a point in time, regardless of the length of contract or other factors. The recognition of revenue aligns with the timing of when promised goods or services are transferred to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. To achieve this core principle, we apply the following five steps in accordance with its revenue policy:

                (1)  Identify the contract with a customer

                (2)  Identify the performance obligations in the contract

                (3)  Determine the transaction price

                (4)  Allocate the transaction price to performance obligations in the contract

                (5)  Recognize revenue as performance obligations are satisfied

     On certain contracts, we apply recognition of revenue over time, which is similar to the method we applied under previous guidance (i.e. percentage of completion). Due to uncertainties inherent in the estimation process, it is possible that estimates of costs to complete a performance obligation will be revised in the near-term. For those performance obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress toward complete satisfaction of the performance obligation, are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. When the current estimate of total costs for a performance obligation indicate a loss, a provision for the entire estimated loss on the unsatisfied performance obligation is made in the period in which the loss becomes evident. 

44

Critical Accounting Policies (continued)

     For product or equipment sales, we apply recognition of revenue when the customer obtains control over such goods, which is at a point in time.

     On October 3, 2019, we entered into an Exclusive License Agreement (“ELA” ) pursuant to which we granted an exclusive license for our technology as outlined in the ELA. The ELA is described below. Under the ELA, we were to receive royalty payments based upon gross revenues earned by the licensee for commercialized products within the field of design and project management platforms for residential use, including single-family residences and multi-family residences, but excluding military housing. We have determined that the ELA granted the licensee a right to access our intellectual property throughout the license period (or its remaining economic life, if shorter), and thus recognizes revenue over time as the licensee recognizes revenue and we have the right to payment of royalties. No revenue has been recognized under the ELA for the six months ended June 30, 2021.  On June 15, 2021 we terminated the Exclusive License Agreement with CPF that we had entered into on October 3, 2019. 

    We entered into a joint venture agreement with Clarity Lab Solutions, LLC (“Clarity Labs”) (the “JV”) in the fourth quarter of 2020. Revenue from the activities of the JV is related to clinical testing services and is recognized when services have been rendered, which is at a point in time.  In addition, we formed Chicago Airport Testing, LLC which collects rental revenue. During the six months ending June 30, 2021, we recognized $15,621,142 in revenue related to activities through the two JV's, which are included in medical revenue on the accompanying consolidated statements of operations.

    We acquired a 10% non-dilutable equity interest for JDI-Cumberland Inlet, LLC and acquired a 50% membership interest in Norman Berry II Owner LLC in the second quarter of 2021. We have determined we are not the primary beneficiary and thus will not consolidated the activities on the condensed consolidated financial statements. We will use the equity method to report the activities as an investment in on our condensed consolidated financial statements. 

Goodwill – Goodwill represents the excess of reorganization value over the fair value of identified net assets upon emergence from bankruptcy. In accordance with the accounting guidance on goodwill, we perform our impairment test of goodwill at the reporting unit level each fiscal year, or more frequently if events or circumstances change that would more likely than not reduce the fair value of its reporting unit below its carrying value. Our evaluation of goodwill completed during the year ended December 31, 2020, resulted in no impairment loss. There was no impairment during the six months ended June 30, 2021.

Intangible assets – Intangible assets consist of $2,766,000 of proprietary knowledge and technology which is being amortized over 20 years, $97,164 of trademarks which is being amortized over 5 years, $47,800 of website fees which is being amortized over 5 years. Our evaluation of intangible assets for impairment during the year ended December 31, 2020, determined that there were no impairment losses. There was no impairment during the six months ended June 30, 2021.

New Accounting Pronouncements

See Note 3 to the accompanying consolidated financial statements for all recently adopted and new accounting pronouncements.

Non-GAAP Financial Information

In addition to our results under GAAP, we also present 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 us and our 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 our 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: 

● They do not reflect our 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.

Other companies, including other companies in our industry, may not use such measures or may calculate one or more of the measures differently than as presented in this Quarterly Report on Form 10-Q, limiting their usefulness as a comparative measure.  

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.

Not applicable.

ITEM 4.      Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Management of SG Blocks, Inc., with the participation of our Principal Executive Officer and Principal Financial Officer, carried out an evaluation of the effectiveness of our “disclosure controls and procedures” (as defined in the Securities Exchange Act of 1934, as amended (the “Exchange Act”), Rules 13a-15(e) or 15d-15(e)) as of the end of the period covered by this Quarterly Report on Form 10-Q (the “Evaluation Date”). Based upon that evaluation, our Principal Executive Officer and Principal Financial Officer concluded that, as of the Evaluation Date, our disclosure controls and procedures were not effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act (i) is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms and (ii) is accumulated and communicated to our management, including our Principal Executive Officer and Principal Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

The Principal Executive Officer and the Principal Financial Officer believe that the condensed consolidated financial statements and other information contained in this Quarterly Report on Form 10-Q present fairly, in all material respects, our business, financial condition and results of operations.

As previously reported, management had identified a deficiency in our internal control over financial reporting, which was related to the timely closing of the accounting records and technical accounting guidance to complex and/or new transactions. Our management had concluded that we do not maintain effective controls related to both deficiencies surrounding the timely closing of the accounting records and technical accounting guidance. Management had determined that the aggregate impact of this deficiency resulted in a material weakness. The material weakness did not result in any identified misstatements in the current period consolidated financial statements, nor in any restatements of consolidated financial statements previously reported by us, and there were no changes in previously released financial results.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company's annual or interim financial statements will not be prevented or detected on a timely basis.

Remediation Steps to Address the Material Weakness

Since identifying the material weakness related to the timely closing of accounting records and technical accounting guidance to complex and/or new transactions, we have taken steps to strengthen the control function related to the financial closing process. These steps include retaining two additional senior accounting resources to help enhance the timeliness of the accounting close process and to have additional oversight for new and complex accounting transactions. We also engaged an outside consulting firm in the second quarter of 2021 to assist the Company with enhancing its accounting practices. We will continue to enhance controls to ensure the financial closing process is effectively implemented. Although we plan to complete this remediation process as quickly as possible, we cannot at this time estimate when the remediation will be completed.

Changes in Internal Control over Financial Reporting

Other than as described above, for the fiscal quarter ended June 30, 2021, there have been no changes in our internal control over financial reporting identified in connection with the evaluations required by Rule 13a-15(d) or Rule 15d-15(d) under the Exchange Act that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. 

Inherent Limitations on Effectiveness of Controls

Our management, including our CEO and our CFO, do not expect that our disclosure controls or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

The information included in "Note 16 - Commitments and Contingencies" of the Company's condensed consolidated financial statements included elsewhere in this Form 10-Q is incorporated by reference into this Item.

ITEM 1A.  Risk Factors

Investing in our common stock involves a high degree of risk. You should consider carefully the following risks, together with all other information in this Quarterly Report on Form 10-Q, including our unaudited condensed consolidated financial statements and notes thereto. If any of the following risks actually materializes, our operating results, financial condition and liquidity could be materially adversely affected. As a result, the trading price of our common stock could decline and you could lose part or all of your investment. The following information updates, and should be read in conjunction with, the information disclosed in Part I, Item 1A, "Risk Factors," contained in the Annual Report on Form 10-K for the year ended December 31, 2020 as amended by the Amendment No. 1 thereto (the “2020 Form 10-K”). There have been no material changes from the risk factors disclosed in “Part I—Item 1A. Risk Factors” in our 2020 Form 10-K, except as follows:

If we are not successful in our efforts to increase sales or raise capital, we could experience a shortfall in cash over the next twelve months, and our ability to obtain additional financing on acceptable terms, if at all, may be limited.

At June 30, 2021 and December 31, 2020, we had cash and cash equivalents, collectively, of $2,323,599 and $13,010,356, respectively. However, during the six months ended June 30, 2021 and year ended December 31, 2020, we reported a net loss of $993,925 and $4,508,162, respectively, and used $1,307,944 and $2,887,950 of cash for operations, respectively. If we are not successful with our efforts to increase revenue, we could experience a shortfall in cash over the next twelve months. If there is a shortfall, we may be forced to reduce operating expenses, among other steps, all of which would have a material adverse effect on our operations going forward.

We may also seek to obtain debt or additional equity financing to meet any cash shortfalls. The type, timing and terms of any financing we may select will depend on, among other things, our cash needs, the availability of other financing sources and prevailing conditions in the financial markets. However, there can be no assurance that we will be able to secure additional funds if needed and that, if such funds are available, the terms or conditions would be acceptable to us. If we are unable to secure additional financing, further reduction in operating expenses might need to be substantial in order for us to ensure enough liquidity to sustain our operations. Any equity financing would be dilutive to our stockholders. If we incur debt, we will likely be subject to restrictive covenants that significantly limit our operating flexibility and require us to encumber our assets. If we fail to raise sufficient funds and continue to incur losses, our ability to fund our operations, take advantage of strategic opportunities, or otherwise respond to competitive pressures will be significantly limited. Any of the above limitations could force us to significantly curtail or cease our operations, and you could lose all of your investment in our common stock. These circumstances have raise substantial doubt about our ability to continue as a going concern, and continued cash losses may risk our status as a going concern. Our consolidated financial statements do not include any adjustments that might be necessary should we be unable to continue as a going concern. 

In December 2019, a novel strain of coronavirus, COVID-19, was reported to have surfaced in Wuhan, China. Since then, the COVID-19 coronavirus has spread to multiple countries, including the United States. The impact of the COVID-19 coronavirus outbreak, or similar global health concerns, has negatively impacted our ability to source certain materials and product pricing, could impact our customers’ ability or that of our licensee to obtain financing and may continue to have a negative impact on our business.

In March 2020, the World Health Organization declared COVID-19 a global pandemic. This contagious disease outbreak, which has continued to spread, and the related adverse public health developments, have adversely affected work forces, economies and financial markets globally. Our ability to obtain and source certain materials, especially lumber, from third-party suppliers has been negatively impacted by the COVID-19 coronavirus outbreak. In addition, any outbreak of COVID at our Echo facility could result in closures of the facility and negatively impact our ability to meet timelines. To date, we have experienced some delays and cost-overruns in projects due to COVID-19. Any quarantines, the timing and length of containment and eradication solutions, travel restrictions, absenteeism by infected workers, labor shortages or other disruptions to our suppliers and their contract manufacturers or our customers would likely adversely impact our sales and operating results and result in further project delays. In addition, the pandemic could result in an economic downturn that could affect the ability of our customers and licensees to obtain financing and therefore impact demand for our products. Order lead times could be extended or delayed and pricing could continue to increase.  Some products or services may become unavailable if the regional or global spread were significant enough to prevent alternative sourcing. Accordingly, we are considering alternative product sourcing in the event that product supply becomes problematic. We expect this global pandemic to have a negative impact on our revenue and our results of operations, the size and duration of which we are currently unable to predict.

48

In addition, the outbreak of the COVID-19 coronavirus could disrupt our operations due to absenteeism by infected or ill members of management or other employees, or absenteeism by members of management and other employees who elect not to come to work due to the illness affecting others in our office or other workplace, or due to quarantines. COVID-19 illness could also impact members of our Board of Directors resulting in absenteeism from meetings of the directors or committees of directors, and making it more difficult to convene the quorums of the full Board of Directors or its committees needed to conduct meetings for the management of our affairs.

The global outbreak of the COVID-19 coronavirus continues to rapidly evolve. The extent to which the COVID-19 coronavirus may impact our business and clinical trials will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the outbreak, travel restrictions and social distancing in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the disease.

We may be unable to successfully integrate the Echo business with its current management and structure and the acquisition of Echo may not result in the benefits anticipated.

Our failure to successfully complete the integration of Echo could have an adverse effect on our prospects, business activities, cash flow, financial condition, results of operations and stock price. Integration challenges may include the following:

• assimilating Echo’s technology and retaining personnel;
  
• estimating the capital, personnel and equipment required for Echo based on the historical experience of management with the businesses;
  
• managing cost overruns on fixed-price legacy Echo projects as a result of delays in deliveries of, and increased costs for, materials for projects, especially lumber, due to COVID-19;
  
• minimizing potential adverse effects on existing business relationships; and
  
• successfully developing new products and services. 

There can be no assurance that the anticipated benefits of the Echo acquisition will materialize or that if they materialize will result in increased stockholder value or revenue stream to the combined company.

The loss of one or a few customers could have a material adverse effect on us.

A few customers have in the past, and may in the future, account for a significant portion of our revenues in any one year or over a period of several consecutive years. For example, for the six months ended June 30, 2021 approximately 71% of our revenue was generated from one customers and for the year ended December 31, 2020, approximately 61% of our revenue was generated from three customers. Although we have contractual relationships with many of our significant customers, our customers may unilaterally reduce or discontinue their contracts with us at any time. The loss of business from a significant customer could have a material adverse effect on our business, financial condition, results of operations and cash flows. 

The inability to secure materials and products from our suppliers in a timely manner or at competitive prices could adversely affect our business.

We have relationships with key materials vendors, and we rely on suppliers for our purchases of products from them. The worldwide spread of the COVID-19 has, among other things resulted in delays in deliveries of, and increased costs for, materials, especially lumber, in projects which we expect to continue to have an impact on our revenue and our results of operations. Any inability to obtain materials or services in the volumes required and at competitive prices from our major trading partners, the loss of any major trading partner or the discontinuation of vendor financing (if any) may seriously harm our business because we may not be able to meet the demands of our customers on a timely basis in sufficient quantities or at all. In addition, we have experienced cost overruns on fixed-price legacy Echo projects as a result of delays in deliveries of, and increased costs for, materials for projects, especially lumber. Other factors, including reduced access to credit by our vendors resulting from economic conditions, may impair our vendors’ ability to provide products in a timely manner or at competitive prices.  We also rely on other vendors for critical services such as transportation, supply chain and professional services.  Any negative impacts to our business or liquidity could adversely impact our ability to establish or maintain these relationships. For the six months ended June 30, 2021 48% of our costs of revenue related to three vendors.  For the year ended December 31, 2020, there were no vendors which represented 10% or more of our cost of revenue.

49

Our clients may adjust, cancel or suspend the contracts in our backlog; as such, our backlog is not necessarily indicative of our future revenues or earnings. In addition, even if fully performed, our backlog is not a good indicator of our future gross margins.

Backlog represents the total dollar amount of revenues we expect to record in the future as a result of performing work under contracts we have been awarded. Backlog may fluctuate significantly due to the timing of orders or awards for large projects and is not necessarily indicative of future backlog levels or the rate at which backlog will be recognized as revenue. We include in backlog only those contracts for which we have reasonable assurance that the customer can obtain the permits for construction and can fund the construction. As of December 31, 2020, our backlog totaled approximately $25.1 million and as of June 30, 2021, our backlog totaled approximately $21 million. The decrease in backlog at June 30, 2021 from December 31, 2020 is primarily attributable to work in progress or completed contracts during the first six months of 2021 for approximately $5.3 million and executing one contract during the first quarter of 2021 in the amount of approximately $1.3 million.  Our backlog is described more in detail in “Note 12—Construction Backlog” of the notes to our consolidated financial statements included elsewhere in this Quarterly Report. We cannot provide assurance that our backlog will be realized as revenues in the amounts reported or, if realized, will result in profits. In accordance with industry practice, substantially all of our contracts are subject to cancellation, termination or suspension at our customer’s discretion. In the event of a project cancellation, we generally would not have a contractual right to the total revenue reflected in our backlog. Projects can remain in backlog for extended periods of time because of the nature of the project and the timing of the particular services required by the project. In addition, the risk of contracts in backlog being cancelled or suspended generally increases during periods of widespread economic slowdowns or in response to changes in commodity prices.

The contracts in our backlog are subject to changes in the scope of services to be provided and adjustments to the costs relating to the contracts. The revenue for certain contracts included in backlog is based on estimates. Additionally, our performance of our individual contracts can affect greatly our gross margins and, therefore, our future profitability. We can provide no assurance that the contracts in backlog, assuming they produce revenues in the amounts currently estimated, will generate gross margins at the rates we have realized in the past.

The issuance of shares of our common stock upon the exercise of outstanding options, warrants and restricted stock units may dilute the percentage ownership of the then-existing stockholders and may make it more difficult to raise additional equity capital.

At June 30, 2021, there were options, including options granted to non-employees and non-directors, restricted stock units and warrants to purchase 36,436, 884,344 and 126,890 shares of common stock, respectively, outstanding that could potentially dilute future net income per share. Because we had a net loss as of June 30, 2021, it is prohibited from including potential common shares in the computation of diluted per share amounts. Accordingly, we used the same number of shares outstanding to calculate both the basic and diluted loss per share. At June 30, 2020, there were options, including options to non-employees and non-directors, restricted stock units and warrants to purchase 52,337, 44,518 and 353,190 shares of common stock, respectively, outstanding that could potentially dilute future net income per share.

Our residential construction business is difficult to evaluate because we recently changed our business model.

From October 2019 until June 2021, our residential construction business was operated under a licensing model.  We recently terminated the licensing business model for our residential construction business in the United States. There is a risk that we will be unable to successfully generate revenue from this new business model or generate profit as we will not be responsible for supplying the capital, personnel and equipment for our residential construction projects. There can be no assurance that we will generate the income that we anticipate.  We are subject to many risks associated with this business model such as our dependence upon suppliers and contractors to perform services. There is no assurance that our activities will be successful or will result in any revenues or profit. Even if we generate revenue, there can be no assurance that we will be profitable.

Our projections of the number of units we anticipate building for each project and the timelines although based upon assumptions that we believe are reasonable, may not be realized.

We have provided projections of our development plans that include the number of units we plan to develop for certain projects and the timelines for commencement and completion of such development activities  which are based upon current contracts that we have entered into, anticipated timelines to complete such projections and current estimates of costs and expenses associated with such projects.  For certain projects such as the JDI-Cumberland project, we must submit budgets that require approval in order for SG Echo to be awarded the fabrication and installation work anticipated to be awarded to SG Echo. Although we have based our projections upon assumptions that we believe are reasonable, our projections may not be realized. The projected and actual results will vary, and those variations may be material and likely to increase over time, and the inclusion of the projections in this Quarterly Report on Form 10-Q should not be regarded as a representation or guarantee by us that the projections will be achieved. These projections are only predictions and actual events or results may differ from those in the projections.

Description of Business [Abstract]

Description of Business

1. Description of Business 

SG Blocks, Inc. (collectively with its subsidiaries, the “Company,” “we”, “us” or “our”) was previously known as CDSI Holdings, Inc., a Delaware corporation incorporated on December 29, 1993. On November 4, 2011, CDSI Merger Sub, Inc., 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. 

The building products developed with our proprietary technology and design and engineering expertise are generally stronger, more durable, environmentally sensitive, and erected in less time than traditional construction methods. The use of the SGBlocks building structure typically provides between four to six points towards the Leadership in Energy and Environmental Design (“LEED”) certification levels, including reduced site disturbance, resource reuse, recycled content, innovation in design and use of local and regional materials. Due to the ability of SGBlocks to satisfy such requirements, we believe the products produced utilizing our technology and expertise is a leader in environmentally sustainable construction.

There are three core product offerings that utilize our technology and engineering expertise. The first product offering involves GreenSteel™ modules, which are the structural core and shell of an SGBlocks building. We procure the containers, engineer required openings with structural steel enforcements, paint the SGBlocks and then deliver them on-site, where the customer or a customer’s general contractor will complete the entire finish out and installation. The second product offering involves replicating the process to create the GreenSteel product and, in addition, installing selected materials, finishes and systems (including, but not limited to floors, windows, doors, interior painting, electrical wiring and fixtures, plumbing outlets and bathrooms, roofing system) and delivering SGBlocks pre-fabricated containers to the site for a third party licensed general contractor to complete the final finish out and installation. Finally, the third product offering is the completely fabricated and finished SGBlocks building (including but not limited to floors, windows, doors, interior painting, electrical wiring and fixtures, plumbing outlets and bathrooms, roofing systems), including erecting the final unit on site and completing any other final steps. The building is ready for occupancy and/or use as soon as installation is completed. Construction administration and/or project management services are typically included in our product offerings.

The Company also provides engineering and project management services related to the use and modification of Modules in construction. 

During 2020, the Company formed, SG Echo, LLC, a wholly owned subsidiary of the Company. SG Echo, LLC was formed to complete the business acquisition as disclosed in Note 9. The Company acquired substantially all the assets of Echo DCL, a Texas limited liability company, except for Echo's real estate holdings for which we obtained a right of first refusal. Echo is a container/modular manufacturer based in Durant, Oklahoma specializing in the design and construction of permanent modular and temporary modular buildings and was one of the Company's key supply chain partners. Echo caters to the military, education, administration facilities, healthcare, government, commercial and residential customers. This acquisition has allowed the Company to expand its reach for the Modules and offer an opportunity to vertically integrate a large portion of the Company's cost of goods sold, as well as increase margins, productivity and efficiency in the areas of design, estimating, manufacturing and delivery and to become the manufacturer of the Company's core container and modular product offerings.  The Company also entered into a joint venture with Clarity Lab Solutions LLC., to provide clinical lab testing related to COVID-19.

As of January 2021, the Company’s condensed consolidated financial statements include the accounts of Chicago Airport Testing LLC (“CAT”). The Company has a variable interest in CAT as described further below. CAT is in the business of marketing, selling, distributing leasing and otherwise commercially exploiting certain products and services in the COVID-19 testing and other medical industry.

In addition, during 2021, the Company formed SGB Development Corp. (“SGB Development”), which is wholly-owned by the Company. SGB Development was formed with the purpose of real property development utilizing the Company's technologies.  SGB Development has a minority interest in Norman Berry II Owners LLC and JDI-Cumberland Inlet LLC as described further below.   

Reverse Stock Split

On February 5, 2020, the Company effected a 1-for-20 reverse stock split of its then-outstanding common stock, which has since been converted. All share and per share amounts set forth in the condensed consolidated financial statements of the Company have been retroactively restated to reflect the 1-for-20 reverse stock split as if it had occurred as of the earliest period presented and unless otherwise stated, all other share and per share amounts for all periods presented in these condensed consolidated financial statements have been adjusted to reflect the reverse stock split effected in February 2020.

As of June 30, 2021, the Company had 8,822,489 shares of common stock issued and outstanding.

2. Liquidity 

As of June 30, 2021, the Company had cash and cash equivalents of $2,323,599 and a backlog of approximately $21 million. See Note 12 for a discussion of construction backlog. Based on our conversations with key customers, the Company anticipates its backlog to convert to revenue over the following period: 

	2021
Within 1 year	$	8,179,581
1 to 2 years		12,856,250
Total Backlog	$	21,035,831

The Company has incurred losses since its inception and has negative operating cash flows. Management has taken several actions to ensure that the Company will continue as a going concern. As described below, the Company has been able to raise substantial cash through equity offerings. In addition, as further described in these consolidated financial statements, the Company has begun to recognize revenue from new revenue streams. Management believes that these actions will enable the Company to continue as a going concern.  

The Company completed a public offering in April and May 2020, which resulted in net proceeds of approximately $1,522,339, and $15,596,141, respectively. See Note 13 for a discussion on these public offerings. The Company believes that it has adequate cash balances to meet obligations coming due in the next twelve months and further intends to meet its capital needs from revenue generated from operations and by containing costs, entering into strategic alliances, as well as exploring other options, including the possibility of raising additional debt or equity capital as necessary. There is, however, no assurance the Company will be successful in meeting its capital requirements prior to becoming cash flow positive.  The Company does not have any additional sources secured for future funding, and if it is unable to raise the necessary capital at the times it requires such funding, it may need to materially change its business plan, including delaying implementation of aspects of such business plan or curtailing or abandoning such business plan altogether.   

With the global spread of the ongoing novel coronavirus ("COVID-19") pandemic during 2020, the Company implemented business continuity plans designed to address and mitigate the impact of the COVID-19 pandemic on its employees and business. Any quarantines, the timing and length of containment and eradication solutions, travel restrictions, absenteeism by infected workers, labor shortages or other disruptions to the Company's suppliers and contract manufacturers or customers would likely adversely impact the Company's sales and operating results and result in further project delays. In addition, the pandemic could result in an economic downturn that could affect the demand for the Company's products. Order lead times could be extended or delayed and pricing could increase. Some products or services may become unavailable if the regional or global spread were significant enough to prevent alternative sourcing. Accordingly, the Company is considering alternative product sourcing in the event that product supply becomes problematic. The Company expects this global pandemic to have an impact on the Company's revenue and results of operations, the size and duration of which the Company is currently unable to predict. In addition, to the extent the ongoing COVID-19 pandemic adversely affects the Company's business and results of operations, it may also have the effect of heightening many of the other risks and uncertainties which the Company faces. The Company has been impacted by COVID-19 with supply chain distributions, absenteeism by infected workers and skilled labor shortages which has caused delays in projects and the Company could be further impacted if the COVID-19 pandemic continues.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

3. Summary of Significant Accounting Policies

Basis of presentation and principals of consolidation – The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions to the Current Report on Form 10-Q and Article 8 Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for annual financial statements. The condensed financial statements and notes should be read in conjunction with the consolidated financial statements and notes for the year ended December 31, 2020 included in the Company's Annual Report on Form 10-K for the year ended December 31, 2020, as filed with the Securities and Exchange Commission on April 15, 2021. In the opinion of management, all adjustments, consisting of normal accruals, considered necessary for a fair presentation of the interim financial statements have been included. Results for the six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021.

Recently adopted accounting pronouncements - New accounting pronouncements implemented by the Company are discussed below or in the related notes, where appropriate.

Accounting estimates – The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Significant areas that require the Company to make estimates include revenue recognition, stock-based compensation, stock warrants liabilities and allowance for credit losses. Actual results could differ from those estimates.

Operating cycle – The length of the Company’s contracts varies, but is typically between six to twelve months. In some instances, the length of the contract may exceed twelve months. Assets and liabilities relating to contracts are included in current assets and current liabilities, respectively, in the accompanying balance sheets as they will be liquidated in the normal course of contract completion, which at times could exceed one year.

Revenue recognition – The Company determines, at contract inception, whether it will transfer control of a promised good or service over time or at a point in time, regardless of the length of contract or other factors. The recognition of revenue aligns with the timing of when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. To achieve this core principle, the Company applies the following five steps in accordance with its revenue policy:

                (1)  Identify the contract with a customer

                (2)  Identify the performance obligations in the contract

                (3)  Determine the transaction price

                (4)  Allocate the transaction price to performance obligations in the contract

                (5)  Recognize revenue as performance obligations are satisfied

On certain contracts, the Company applies recognition of revenue over time, which is similar to the method the Company applied under previous guidance (i.e. percentage of completion). Due to uncertainties inherent in the estimation process, it is possible that estimates of costs to complete a performance obligation will be revised in the near-term. For those performance obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress toward complete satisfaction of the performance obligation, are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. When the current estimate of total costs for a performance obligation indicate a loss, a provision for the entire estimated loss on the unsatisfied performance obligation is made in the period in which the loss becomes evident. 

For product or equipment sales, the Company applies recognition of revenue when the customer obtains control over such goods, which is at a point in time.

On October 3, 2019, the Company entered into an Exclusive License Agreement (“ELA” ) pursuant to which it granted an exclusive license for its technology as outlined in the ELA. The ELA is described below. Under the ELA, the Company will receive royalty payments based upon gross revenues earned by the licensee for commercialized products within the field of design and project management platforms for residential use, including single-family residences and multi-family residences, but excluding military housing. The Company has determined that the ELA grants the licensee a right to access the Company’s intellectual property throughout the license period (or its remaining economic life, if shorter), and thus recognizes revenue over time as the licensee recognizes revenue and the Company has the right to payment of royalties. No revenue has been recognized under the ELA for the six months ended June 30, 2021 and 2020. On June 15, 2021, the Company terminated the ELA that was executed on October 3, 2019 which is discussed below.   

CMC Right of First Refusal Agreement – On October 9, 2019, the Company entered into a Right of First Refusal Agreement (the “Agreement”) with CMC Development LLC (“CMC”), which has a term of two (2) years. Under the Agreement, the Company has a right of first refusal with respect to being engaged as a designer and builder of any real estate projects for which CMC has secured the rights to develop and in which CMC has a greater than fifty percent (50%) interest in the owner or developer entity and has the right to select the builder for such real estate project (the “ROFR Rights”). In exchange for such ROFR Rights, the Company agreed to issue to CMC 2,500 shares of restricted stock of the Company’s common stock, of which 1,250 shares vested on March 31, 2021 and the remaining 1,250 shares will vest and be issued on September 30, 2021, unless the Agreement is earlier terminated. In the event that the Agreement is earlier terminated, CMC will still be entitled to receive the entire amount of such restricted stock that has vested as of such earlier termination date, but in no event less than 1,250 shares of such restricted stock. The Agreement also provides for customary indemnification and confidentiality obligations between the parties. The 2,500 shares of restricted stock of the Company's common stock has yet to be issued to CMC. 

The Agreement also provides that CMC has engaged the Company to build and design, in the aggregate, approximately 100 residential and commercial units at 1100 Ridge Avenue, Atlanta, Georgia, which is known as the “Ridge Avenue, Atlanta Project.” The total expected gross revenue to the Company for the project to be derived by CMC is approximately $16,900,000. The project is a residential project but it was not subject to the recently terminated Exclusive License Agreement, dated October 3, 2019. The planning stage of the project was initial delayed due to COVID-19 but the project is still active. No revenue has been recognized under the Agreement for the six months ended June 30, 2021 or 2020. 

The Company entered into a joint venture agreement with Clarity Lab Solutions, LLC (“Clarity Labs”) (the “JV”) in the fourth quarter of 2020. Revenue from the activities of the JV is related to clinical testing services and is recognized when services have been rendered, which is at a point in time.  Included in the consideration the Company expected to be entitled to receive, the Company estimates its contractual allowances, payer denials and price concessions. During the six months ended June 30, 2021, the Company recognized approximately $15,000,000 related to activities through the JV, which is included in medical revenue on the accompanying consolidated statements of operations. In addition, the Company formed Chicago Airport Testing, LLC which is currently collecting rental revenue from subleasing to a consortium of government entities assisting in COVID-19 testing. 

Disaggregation of Revenues

The Company’s revenues are derived from construction and engineering contracts related to Modules, and medical revenue derived from lab testing and test kit sales. The Company's contracts are with customers in various industries. Revenue recognized at a point in time and recognized over time were $15,750,903 and $5,290,711, respectively, for the six months ending June 30, 2021. All revenue recognized for the six months ending June 30, 2020 was over time.

Contract Assets and Contract Liabilities

Accounts receivable are recognized in the period when the Company’s right to consideration is unconditional. Accounts receivable are recognized net of an allowance for credit losses. A considerable amount of judgment is required in assessing the likelihood of realization of receivables.

The timing of revenue recognition may differ from the timing of invoicing to customers. 

Contract assets include unbilled amounts from long-term construction services when revenue recognized under the cost-to-cost measure of progress exceeds the amounts invoiced to customers, as the amounts cannot be billed under the terms of our contracts. Such amounts are recoverable from customers based upon various measures of performance, including achievement of certain milestones, completion of specified units or completion of a contract. Contract assets are generally classified as current within the condensed consolidated balance sheets.  

Contract liabilities from construction and engineering contracts occur when amounts invoiced to customers exceed revenues recognized under the cost-to-cost measure of progress. Contract liabilities additionally include advanced payments from customers on certain contracts. Contract liabilities decrease as the Company recognizes revenue from the satisfaction of the related performance obligation. Contract liabilities are generally classified as current within the condensed consolidated balance sheet. 

Although the Company believes it has established adequate procedures for estimating costs to complete on open contracts, it is at least reasonably possible that additional significant costs could occur on contracts prior to completion. The Company periodically evaluates and revises its estimates and makes adjustments when they are considered necessary.

Deferred Contract Costs - Prior to entering into the ELA, the Company was subject to an agreement to construct and develop a certain property (“Original Agreement”), which now was subject to the ELA. Because of this, the Company is no longer obliged to its Original Agreement. Upon entering the ELA, the Company had an outstanding accounts receivable balance of $306,143, which was forfeited and recognized this amount as deferred contract costs. This amount was offset by $102,217, which was reimbursement from the licensee for project costs on this project.  The Company incurred total deferred contract costs of $203,926.  The Company considered this amount an incremental cost of obtaining that ELA, because the Company expected to recover those costs through future royalty payments. The Company initially planned to amortize the asset over sixty months, which is the initial term of the ELA because the asset relates to the services transferred to the customer during the contract term. As of June 30, 2021, accumulated amortization related to deferred contract costs amounted to $71,374. During the six months ended June 30, 2021 and 2020, amortization expense relating to the deferred contract costs amounted to $20,392 and $20,393, respectively, and is included in general and administrative expenses on the accompanying condensed consolidated statement of operations.  As previously mentioned, the ELA was terminated on June 15, 2021 but the Company expects to recover the deferred contract costs from the Assignment of Limited Rights Under Membership Interest Redemption Agreement, dated June 15, 2021 as described below.  

Exclusive License Agreement – On October 3, 2019, as amended on October 17, 2019, the Company entered into the ELA with CPF GP 2019-1 LLC (the “Licensee”), pursuant to which the Company granted the Licensee an exclusive license (the “License”) solely within the United States and its legal territories to the Company’s technology, intellectual property, any improvements thereto, and any related permits, in order to develop and commercialize products within the field of design and project management platforms for residential use, including single-family residences and multi-family residences, but excluding military housing. The Ridge Avenue Project has also been excluded from the License. The License Agreement had an initial term of five (5) years and was to automatically renew for subsequent five (5) year periods. The License Agreement provided for customary terminating provisions, including the right by the Company to terminate if the Licensee fails to make minimum royalty payments (as described below).

In consideration for the License, during the initial term, the Licensee agreed to pay the Company a royalty of (x) five percent (5%) on the first $20,000,000 of gross revenues derived from the Licensee’s commercialization of the License (net of customary discounts, sales taxes, delivery charges, and amounts for returns) (the “Gross Revenues”), (y) four and one-half percent (4.5%) on the next $30,000,000 of Gross Revenues, and (z) five percent (5%) on all Gross Revenues thereafter (collectively, the “Royalty”) , subject to the following minimum royalty payments determined on a cumulative basis during the initial term: $500,000 in year 1, $750,000 in year 2, $1,500,000 in year 3, $2,000,000 in year 4, and $2,500,000 in year 5. License Agreement provided that if it was extended beyond the initial term, then the parties would negotiate in good faith the royalty rate and the minimum royalty payments for the renewal term(s). In addition, to the extent the Licensee sublicenses any aspect of the License to a sub-licensee, the Licensee was obligated to pay to the Company fifty percent (50%) of all payments received by the Licensee from such sublicensee. The License Agreement also provided that the Company could also provide the Licensee with professional services with respect to the License, and the Licensee was obligated to the Company for employees’ time, materials, and expenses incurred in providing such professional services. The Licensee also separately agreed to reimburse the Company for any third-party expenses incurred by the Company in developing the Company’s remaining and future residential projects. 

The License Agreement provided for customary indemnification obligations between the parties and further provides that the Licensee will indemnify the Company for any claims arising out of the commercialization of the License by the Licensee or any of its subsidiaries, contractors, or sublicensees. In addition, the License Agreement provided that the Company would provide the Licensee with cost estimates for the fabrication and manufacturing of residential projects in the Company’s existing pipeline as of the date of the License Agreement, and if such projects cannot be reasonably constructed and installed at or below such estimates, then the Licensee may withhold payment of any royalty due to the Company under the License Agreement on a dollar-for-dollar basis to offset the costs above the originally estimated amounts.

On June 15, 2021, the Company terminated the Exclusive License Agreement with CPF that the Company had entered into on October 3, 2019.  In connection with the termination, the Company entered into a Settlement and Mutual Release Agreement (the “Settlement Agreement”) with CPF, the general partner (the “Licensee”) of CPF MF 2019-1 LLC (“CPF MF”), and Capital Plus Financial, LLC, a limited partner of the Licensee (“Capital Plus”) and an Assignment of Limited Rights Under Membership Interest Redemption Agreement, dated June 15, 2021, with Capital Plus and the Licensee. In connection with the termination of that certain Exclusive License Agreement, dated as of October 3, 2019 (the “License Agreement”), with the Licensee Pursuant to the Settlement Agreement with CPF and Capital Plus, the License Agreement was terminated, the Company released CPF and CPF MF for any claims in exchange for releases from CPF and Capital Plus and the Company is receiving an assignment of CPF’s right under certain circumstances to a $1.25 million redemption distribution from CPF MF under its Operating Agreement.

Business Combinations - The Company accounts for business acquisitions using the acquisition method of accounting in accordance with ASC 805 “Business Combinations”, which requires recognition and measurement of all identifiable assets acquired and liabilities assumed at their fair value as of the date control is obtained. The Company determines the fair value of assets acquired and liabilities assumed based upon its best estimates of the acquisition-date fair value of assets acquired and liabilities assumed in the acquisition. Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired. Subsequent adjustments to fair value of any contingent consideration are recorded to the Company’s condensed consolidated statements of operations. Costs that the Company incurs to complete the business combination are charged to general and administrative expenses as they are incurred.

Variable Interest Entities – The Company accounts for certain legal entities as variable interest entities (“VIE"). When evaluating a VIE for consolidation, the Company must determine whether or not there is a variable interest in the entity. Variable interests are investments or other interests that absorb portions of an entity’s expected losses or receive portions of the entity’s expected returns. If it is determined that the Company does not have a variable interest in the VIE, no further analysis is required and the VIE is not consolidated. If the Company holds a variable interest in a VIE, the Company consolidates the VIE when there is a controlling financial interest in the VIE and therefore are deemed to be the primary beneficiary. The Company is determined to have a controlling financial interest in a VIE when it has both the power to direct the activities of the VIE that most significantly impact the VIE economic performance and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to that VIE. This determination is evaluated periodically as facts and circumstances change.

On August 27, 2020 the Company entered into a joint venture agreement with Clarity Lab Solutions, LLC (“Clarity Labs”) (the “JV”).  In consideration and subject to Clarity Lab’s services and commitments and provided the agreement remains valid and in force, and is not terminated, the Company agreed to issue 200,000 restricted shares of SGB common stock over a defined vesting period starting in December 1, 2020. The restricted shares of SGB common stock were not issued to Clarity Labs as certain capital commitments were not met. Clarity Labs is a licensed clinical laboratory that uses specialized molecular testing equipment and that focuses on the diagnosis and treatment of critical diseases, including COVID-19. Clarity Labs is also engaged in the business of manufacturing, importing and distributions various medical tests. Under the JV, the Company and Clarity Labs will jointly market, sell, and distribute certain products and services (“Clarity Mobile Venture”).  As of June 30, 2021, $381,770 was due to Clarity Labs for expenses paid on behalf of Clarity Mobile Venture, and is included in Due to Affiliates on the accompanying consolidated balance sheets. In addition, during the six months ended June 30, 2021, the Company recognized revenue of $60,110 and other income of $60,000 to Clarity Labs, of which $60,000 is included in accounts receivable as of June 30, 2021. The Company has determined it is the primary beneficiary of Clarity Mobile Venture and has thus consolidated the activities in its condensed consolidated financial statements.

On January 18, 2021 the Company entered into an operating agreement to form CAT. The purpose of CAT is to market, sell, distribute, lease and otherwise commercially exploit certain products and services in the COVID-19 testing industry.  The Company has determined it is the primary beneficiary of CAT and has thus consolidated the activities in its condensed consolidated financial statements.

Investment Entities – On May 31, 2021, the Company's subsidiary SGB Development Corp. agreed to contribute $600,000 to acquire a 50% membership interest in Norman Berry II Owner LLC.  The Company contributed $350,329 of the initial $600,000 in the second quarter of 2021 with the remaining amount being funded in the third quarter of 2021.   The purpose of Norman Berry II Owner LLC is to develop and provide affordable housing in the Atlanta, Georgia metropolitan area.  The Company has determined it is not the primary beneficiary of "Norman Berry" and thus will not consolidate the activities in its condensed consolidated financial statements. The Company will use the equity method to report the activities as an investment in on its condensed consolidated financial statements. 

On June 24, 2021, the Company's subsidiary SGB Development Corp. entered into an operating agreement with Jacoby Development for a 10% non-dilutable equity interest for JDI-Cumberland Inlet, LLC.  The Company contributed $3,000,000 for its 10% equity interest.  The purpose of JDI-Cumberland Inlet, LLC is to develop a waterfront parcel in a mixed-use destination community.  The Company has determined it is not the primary beneficiary of JDI-Cumberland Inlet, LLC and thus will not consolidate the activities in its condensed consolidated financial statements.  The Company will use the equity method to report the activities as an investment in on its condensed consolidated financial statements.  

Cash and cash equivalents – The Company considers cash and cash equivalents to include all short-term, highly liquid investments that are readily convertible to known amounts of cash and have original maturities of three months or less upon acquisition. Cash and cash equivalents totaled $2,323,599 as of June 30, 2021 and $13,010,356 as of December 31, 2020. 

Short-term investment – The Company classifies investments consisting of a certificate of deposit with a maturity greater than three months but less than one year as short-term investment.  The Company had no short-term investment as of June 30, 2021 or December 31, 2020, respectively.   

Accounts receivable and allowance for credit losses – Accounts receivable are receivables generated from sales to customers and progress billings on performance type contracts. Amounts included in accounts receivable are deemed to be collectible within the Company’s operating cycle. The Company recognizes accounts receivable at invoiced amounts. 

The allowance for credit losses reflects the Company's best estimate of expected losses inherent in the accounts receivable balances. Management provides an allowance for credit losses based on the Company’s historical losses, specific customer circumstances, and general economic conditions. Periodically, management reviews accounts receivable and adjusts the allowance based on current circumstances and charges off uncollectible receivables when all attempts to collect have been exhausted and the prospects for recovery are remote. Recoveries are recognized when they are received. Actual collection losses may differ from our estimates and could be material to our condensed consolidated financial position, results of operations, and cash flows. 

Inventory – Raw construction materials (primarily shipping containers and fabrication materials) are valued at the lower of cost (first-in, first-out method) or net realizable value. Finished goods and work-in-process inventories are valued at the lower of cost or net realizable value, using the specific identification method. Medical equipment and COVID-19 test and testing supplies are valued at the lower of cost, (first-in, first-out method) or net realizable value. As of June 30, 2021 there was inventory of $4,429 for construction materials, and $1,405,486 of medical equipment and COVID-19 test and testing supplies. As of December 31, 2020 there was inventory of $4,429 for construction materials, and $773,715 of medical equipment and COVID-19 test and testing supplies. 

Goodwill – The Company performs its impairment test of goodwill at the reporting unit level each fiscal year, or more frequently if events or circumstances change that would more likely than not reduce the fair value of its reporting unit below its carrying values. The Company performs a goodwill impairment test by comparing the fair value of the reporting unit with its carrying value and recognizes an impairment charge for the amount by which the carrying value exceeds the fair value, not to exceed the total amount of goodwill. The amount by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss. There were no impairments during the year ended December 31, 2020 or the six months ended June 30, 2021 and 2020. The Company has taken the recent COVID-19 pandemic into consideration when determining impairment. 

Intangible assets – Intangible assets consist of $2,766,000 of proprietary knowledge and technology, which is being amortized over 20 years. In addition, $97,164 of trademarks, and $47,800 of website costs are being amortized over 5 years.  The Company evaluated intangible assets for impairment during the year ended December 31, 2020, and determined that there were no impairment losses. There was no impairment during the six months ended June 30, 2021 and 2020. The accumulated amortization as of June 30, 2021 and 2020 was $732,085 and $1,686,876, respectively. The amortization expense for the six months ended June 30, 2021 and 2020 was $82,230 and $72,561, respectively. The amortization expense for the three months ended June 30, 2021 and 2020 was $41,823 and $36,281, respectively. The estimated amortization expense for the successive five years is as follows:  

For the year ending December 31,:
2021	$	83,646
2022		162,970
2023		161,176
2024		160,469
2025		157,051
Thereafter		1,453,567
	$	2,178,879

Property, plant and equipment – Property, plant and equipment is stated at cost. Depreciation is computed using the straight-line method over the estimated lives of each asset. Estimated useful lives for significant classes of assets are as follows: computer and software 3 to 5 years, furniture and other equipment 5 to 7 years, automobiles 2 to 5 years, buildings held for lease 5 to 7 years, and equipment 5 to 29 years. Repairs and maintenance are charged to expense when incurred.

Convertible instruments – The Company bifurcates conversion options from their host instruments and accounts for them as free standing derivative financial instruments according to certain criteria. The criteria include circumstances in which (a) the economic characteristics and risks of the embedded derivative instrument are not clearly and closely related to the economic characteristics and risks of the host contract, (b) the hybrid instrument that embodies both the embedded derivative instrument and the host contract is not re-measured at fair value under otherwise applicable generally accepted accounting principles with changes in fair value reported in earnings as they occur and (c) a separate instrument with the same terms as the embedded derivative instrument would be considered a derivative instrument.

Common stock purchase warrants and other derivative financial instruments – The Company classifies as equity any contracts that (i) require physical settlement or net-share settlement or (ii) provides a choice of net-cash settlement or settlement in the Company’s own shares (physical settlement or net-share settlement) providing that such contracts are indexed to the Company’s own stock. The Company classifies as assets or liabilities any contracts that (i) require net-cash settlement (including a requirement to net cash settle the contract if any event occurs and if that event is outside the Company’s control) or (ii) gives the counterparty a choice of net-cash settlement or settlement shares (physical settlement or net-cash settlement). The Company assesses classification of common stock purchase warrants and other free standing derivatives at each reporting date to determine whether a change in classification between assets and liabilities or equity is required.

Fair value measurements – Financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities are carried at cost, which the Company believes approximates fair value due to the short-term nature of these instruments.

The Company measures the fair value of financial assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value.

The Company uses three levels of inputs that may be used to measure fair value:

Level 1	Quoted prices in active markets for identical assets or liabilities.
Level 2	Quoted prices for similar assets and liabilities in active markets or inputs that are observable.
Level 3	Inputs that are unobservable (for example, cash flow modeling inputs based on assumptions).

Transfer into and transfers out of the hierarchy levels are recognized as if they had taken place at the end of the reporting period. 

Share-based payments – The Company measures the cost of services received in exchange for an award of equity instruments based on the fair value of the award. For employees and directors, including non-employee directors, the fair value of a stock option award is measured on the grant date. The fair value amount is then recognized over the period services are required to be provided in exchange for the award, usually the vesting period. The Company recognizes stock-based compensation expense on a graded-vesting basis over the requisite service period for each separately vesting tranche of each award. Stock-based compensation expense to employees and all directors are reported within payroll and related expenses in the consolidated statements of operations. Stock-based compensation expense to non-employees is reported within marketing and business development expense in the condensed consolidated statements of operations.   

Income taxes – The Company accounts for income taxes utilizing the asset and liability approach. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes generally represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from the differences between the financial and tax bases of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted.

The calculation of tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company recognizes liabilities for anticipated tax audit issues based on the Company’s estimate of whether, and the extent to which, additional taxes will be due. If payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when the liabilities are no longer determined to be necessary. If the estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result.

Concentrations of credit risk – Financial instruments, that potentially subject the Company to concentration of credit risk, consist principally of cash and cash equivalents. The Company places its cash with high credit quality institutions. At times, such amounts may be in excess of the FDIC insurance limits. The Company has not experienced any losses in such account and believes that it is not exposed to any significant credit risk on the account.

With respect to receivables, concentrations of credit risk are limited to a few customers in the construction industry. The Company performs ongoing credit evaluations of its customers’ financial condition and, generally, requires no collateral from its customers other than normal lien rights. At June 30, 2021 and December 31, 2020, 62% and 79%, respectively, of the Company’s gross accounts receivable in excess of 10% were due from two and three customers. 

Revenue in excess of 10% relating to one and two customers represented approximately 77% and 72% of the Company's total revenue for the three months ended June 30, 2021 and 2020, respectively. Revenue relating to one and three customers represented approximately 71% and 69% of the Company's total revenue for the six months ended June 30, 2021 and 2020, respectively.

Cost of revenue in excess of 10% relating to three and two vendors represented approximately 52% and 51% of the Company’s total cost of revenue for the three months ended June 30, 2021 and 2020, respectively. Cost of revenue relating to three and four vendors represented approximately 48% and 75% of the Company’s total cost of revenue for the six months ended June 30, 2021 and 2020, respectively. The Company believes it has access to alternative suppliers, with limited disruption to the business, should circumstances change with its existing suppliers.

The Company periodically evaluates and revises its estimates and makes adjustments when they are considered necessary.

On September 17, 2020, the Company, through SG Echo, LLC (its wholly owned subsidiary), entered into an Asset Purchase Agreement (“APA") to acquire substantially all of the assets of Echo DCL, LLC (“Echo”) for $1,059,600 in cash (the “Echo Acquisition”), except for ECHO DCL's real estate holdings. The Echo Acquisition closed on September 23, 2020. In addition, the sellers of Echo have the potential of additional consideration based upon the APA.  In accordance with ASC 805, the Echo Acquisition is accounted for as a business combination. The Echo Acquisition was made for the purpose of expanding the Company’s footprint into the modular manufacturing business. 

The purchase consideration amounted to:

Cash	$	1,059,600
Earnout liability		—
Settlement of accounts receivable and net contract liabilities		(94,980	)
	$	964,620

The settlement of accounts receivable and net contract liabilities represents amounts effectively settled upon the purchase of Echo, which originated from contacts between the Company and Echo prior to the purchase date. 

The following table summarizes the allocation of the purchase price to the assets acquired and liabilities assumed for the Echo Acquisition:   

Cash and cash equivalents	$	316,432
Accounts receivable		252,557
Inventories		130,799
Prepaid expenses and other current assets		7,400
Property, plant and equipment		1,154,818
Right-of-use assets		57,120
Goodwill		85,810
Intangible assets		68,344
Accounts payable and accrued expenses		(733,529	)
Assumed liabilities		(285,204	)
Contract liabilities		(32,807	)
Lease liability		(57,120	)
	$	964,620

As part of the Echo Acquisition, the Company recorded a contingent consideration liability for additional payments due to the sellers of Echo. These payments are due in accordance with the APA and are based upon the net income obtained from the Echo business during certain earnout periods.  The earnout periods conclude as of September 30, 2021. The initial contingent consideration liability of $0 was based on the fair value of the contingent consideration liability at the acquisition date, and is payable in cash and shares of restricted common stock of the Company. Any contingent liability would be paid out in the period after the earn out period, once additional advances are paid in full. As of June 30, 2021, the liability is $0, and no payment has been paid out.

Weighted Average Remaining Lease Term
Operating leases			3.94 years

As the leases do not provide an implicit rate, the Company used an incremental borrowing rate based on the information available at the lease commencement date in determining the present value of the lease payments, which is reflective of the specific term of the leases and economic environment of each geographic region.  

Anticipated future lease costs, which are based in part on certain assumptions to approximate minimum annual rental commitments under non-cancelable leases, are as follows: 

Year Ending December 31,		Operating		Financing		Total
2021	$	226,806	$	10,080	$	236,886

Net Income (Loss) Per Share [Abstract]

Net Income (Loss) Per Share

11. Net Income (Loss) Per Share

Basic net income (loss) per share is computed by dividing the net income (loss) for the period by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by dividing the net income (loss) for the period by the weighted average number of common and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares consist of the common shares issuable upon the exercise of stock options and warrants. Potentially dilutive common shares are excluded from the calculation if their effect is antidilutive. 

At June 30, 2021, there were options, including options granted to non-employees and non-directors, restricted stock units and warrants to purchase 36,436, 884,344 and 126,890 shares of common stock, respectively, outstanding that could potentially dilute future net income per share. Because the Company had a net loss as of June 30, 2021, it is prohibited from including potential common shares in the computation of diluted per share amounts. Accordingly, the Company has used the same number of shares outstanding to calculate both the basic and diluted loss per share. At June 30, 2020, there were options, including options to non-employees and non-directors, restricted stock units and warrants to purchase 52,337, 44,518 and 353,190 shares of common stock, respectively, outstanding that could potentially dilute future net income per share.

The following represents the backlog of signed construction and engineering contracts in existence at June 30, 2021 and December 31, 2020, which represents the amount of revenue the Company expects to realize from work to be performed on uncompleted contracts in progress and from contractual agreements in effect at June 30, 2021 and December 31, 2020, respectively, on which work has not yet begun:

	2021			2020

Balance - end of period	$	21,035,831		$	25,117,461

Backlog at June 30, 2021 included two contracts entered into during the third quarter of 2020 in the amount of approximately $4 million and approximately $2.95 million along with three contracts during the fourth quarter of 2020 in the amount of approximately $2.7 million, $0.80 million, and $0.70 million. In addition, the Company executed one large contract in the first quarter of 2021 in the amount of approximately $1.3 million. The Company expects that all of this revenue will be realized by June 30, 2023. As previously discussed in Note 3, the ELA was terminated and in connection with the termination a Settlement and Mutual Release Agreement was executed. The Company is receiving an assignment of CPF's right to a $1.25 million redemption distribution for one such project.  The Company does not expect to receive any royalties from the terminated ELA and Backlog does not include the redemption distribution fee. 

The Company’s remaining backlog as of June 30, 2021 represents the remaining transaction price of firm contracts for which work has not been performed and excludes unexercised contract options. 

The Company expects to satisfy its backlog which represents the remaining unsatisfied performance obligation on contracts as of June 30, 2021 over the following period:

	2021
Within 1 year	$	8,179,581
1 to 2 years		12,856,250
Total Backlog	$	21,035,831

Although backlog reflects business that is considered to be firm, cancellations, deferrals or scope adjustments may occur. Backlog is adjusted to reflect any known project cancellations, revisions to project scope and cost and project deferrals, as appropriate.

Stock-Based Option Awards 

The Company has issued no stock-based options during the six months ended June 30, 2021 and 2020.   

Because the Company does not have significant historical data on employee exercise behavior, the Company uses the “Simplified Method” to calculate the expected life of the stock-based option awards granted to employees. The simplified method is calculated by averaging the vesting period and contractual term of the options.   

The following table summarizes stock-based option activities and changes during the six months ended June 30, 2021 as described below:

	Shares		Weighted Average Fair Value Per Share		Weighted Average Exercise Price Per Share		Weighted Average Remaining Terms (in years)		Aggregate Intrinsic Value

16. Commitments and Contingencies  

Legal Proceedings

The Company is subject to certain claims and lawsuits arising in the normal course of business. The Company assesses liabilities and contingencies in connection with outstanding legal proceedings utilizing the latest information available. Where it is probable that the Company will incur a loss and the amount of the loss can be reasonably estimated, the Company records a liability in our consolidated financial statements. These legal accruals may be increased or decreased to reflect any relevant developments on a quarterly basis. Where a loss is not probable or the amount of the loss is not estimable, the Company does not record an accrual, consistent with applicable accounting guidance. Based on information currently available, advice of counsel, and available insurance coverage, the Company believes that the established accruals are adequate and the liabilities arising from the legal proceedings will not have a material adverse effect on the consolidated financial condition. However, that in light of the inherent uncertainty in legal proceedings there can be no assurance that the ultimate resolution of a matter will not exceed established accruals. As a result, the outcome of a particular matter or a combination of matters may be material to the results of operations for a particular period, depending upon the size of the loss or the income for that particular period.

Pizzarotti Litigation - On or about August 10, 2018 Pizzarotti, LLC filed a complaint against the Company and Mahesh Shetty, the Company’s former President and CFO, and others, seeking unspecified damages for an alleged breach of contract by the Company and another entity named Phipps & Co. (“Phipps”). The lawsuit was filed as Pizzarotti, LLC. v. Phipps & Co., et al., Index No. 653996/2018 and commenced in the Supreme Court of the State of New York for the County of New York. On or about April 1, 2019, Phipps filed cross-claims against the Company and Mr. Shetty asserting claims for indemnification, contribution, fraud, negligence, negligent misrepresentation, and breach of contract. SG Blocks has likewise cross claimed against Phipps for indemnification and contribution, claiming that any damages to the Plaintiff were the result of the acts or omissions of Phipps and its principals. Pizzarotti’s suit arose from a contract dated April 3, 2018 that it executed with Phipps whereby Pizzarotti, a construction manager, engaged Phipps to perform stone procuring and tile work at a construction project located at 161 Maiden Lane, New York 10038. Pizzarotti’s claims against the Company arise from a purported assignment agreement dated August 10, 2018, whereby Pizzarotti claims that the Company agreed to assume certain obligations of Phipps under a certain trade contract between Pizzarotti and Phipps & Co. Phipps’ claims against the Company arise from a purported Assignment Agreement, dated as of May 30, 2018, between Pizzarotti, Phipps and the Company (the “Assignment Agreement”), pursuant to which, it is alleged, that the Company agreed to provide a letter of credit in connection with the sub-contracted work to be provided by Phipps to Pizzarotti. The Company believes that the Assignment Agreement was void for lack of consideration and moved to dismiss the case on those and other grounds. On June 17, 2020, the New York Supreme Court entered an order dismissing certain claims against the Company brought by cross claimant Phipps & Co. Specifically, the court dismissed Phipps’ claims for indemnification, contribution, fraud, negligence and negligent misrepresentation. The court did not dismiss Phipps’ claim for breach of the Assignment Agreement. The issue of the validity of the Assignment Agreement, and the Company’s defenses to the claims brought by the plaintiff Pizzarotti, and cross claimant Phipps, are being litigated. The Company maintains that the Assignment Agreement, to the extent valid and enforceable, was properly terminated and/or there are no damages, and, consequently, that the claims brought against the Company are without merit. The Company intends to continue to vigorously defend the litigation. The parties have engaged in written discovery but no depositions have been conducted as of yet. By motion dated February 24, 2021, Pizzarotti moved to stay the entire action pending the outcome of a separate litigation captioned Pizzarotti, LLC v. FPG Maiden Lane, LLC et. al., Index No. 651697/2019, involving some of the same parties (but excluding the Company). Phipps cross moved to consolidate the two actions. The Company opposed both motions. On April 26, 2021, the Court denied both motions and directed the parties to meet and confer concerning the scheduling of depositions. On May 10, 2021, the parties jointly filed with the Court a proposed order providing the completion of depositions of all parties and nonparties by September 30, 2021. The parties are currently in the process of scheduling depositions for the latter part of September.

Litigation is subject to many uncertainties, and the outcome of this action is not predicted with assurance. The Company is currently unable to predict the possible loss or range of loss, if any, associated with the resolution of this litigation, and, accordingly, the Company has made no provision related to this matter in the condensed consolidated financial statements.

(i) On January 1, 2019, SG Blocks commenced an action against Teton Buildings, LLC (“Teton”) in Harris County, Texas (“Teton Action”) to recover approximately $2,100,000 arising from defendant’s breach of the operative contract related to Heart of Los Angeles construction project in Los Angeles (the “HOLA Project”) entered into on or about June 2, 2017.

On July 23, 2021, the Company filed a First Amended Third-Party Complaint against Teton and other named third party defendants (see #2 below) which has yet to be served upon Teton.

The Company is currently unable to predict the possible loss or range of loss, if any, associated with the resolution of this litigation, and, accordingly, the Company has made no provision related to this matter in the condensed consolidated financial statements

Summary of Significant Accounting Policies (Policies)

6 Months Ended

Jun. 30, 2021

Accounting Policies [Abstract]

Basis of presentation and principals of consolidation

Basis of presentation and principals of consolidation – The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions to the Current Report on Form 10-Q and Article 8 Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for annual financial statements. The condensed financial statements and notes should be read in conjunction with the consolidated financial statements and notes for the year ended December 31, 2020 included in the Company's Annual Report on Form 10-K for the year ended December 31, 2020, as filed with the Securities and Exchange Commission on April 15, 2021. In the opinion of management, all adjustments, consisting of normal accruals, considered necessary for a fair presentation of the interim financial statements have been included. Results for the six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021.

Recently adopted accounting pronouncements

Recently adopted accounting pronouncements - New accounting pronouncements implemented by the Company are discussed below or in the related notes, where appropriate.

Accounting estimates

Accounting estimates – The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Significant areas that require the Company to make estimates include revenue recognition, stock-based compensation, stock warrants liabilities and allowance for credit losses. Actual results could differ from those estimates.

Operating cycle

Operating cycle – The length of the Company’s contracts varies, but is typically between six to twelve months. In some instances, the length of the contract may exceed twelve months. Assets and liabilities relating to contracts are included in current assets and current liabilities, respectively, in the accompanying balance sheets as they will be liquidated in the normal course of contract completion, which at times could exceed one year.

Revenue recognition

Revenue recognition – The Company determines, at contract inception, whether it will transfer control of a promised good or service over time or at a point in time, regardless of the length of contract or other factors. The recognition of revenue aligns with the timing of when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. To achieve this core principle, the Company applies the following five steps in accordance with its revenue policy:

                (1)  Identify the contract with a customer

                (2)  Identify the performance obligations in the contract

                (3)  Determine the transaction price

                (4)  Allocate the transaction price to performance obligations in the contract

                (5)  Recognize revenue as performance obligations are satisfied

On certain contracts, the Company applies recognition of revenue over time, which is similar to the method the Company applied under previous guidance (i.e. percentage of completion). Due to uncertainties inherent in the estimation process, it is possible that estimates of costs to complete a performance obligation will be revised in the near-term. For those performance obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress toward complete satisfaction of the performance obligation, are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. When the current estimate of total costs for a performance obligation indicate a loss, a provision for the entire estimated loss on the unsatisfied performance obligation is made in the period in which the loss becomes evident. 

For product or equipment sales, the Company applies recognition of revenue when the customer obtains control over such goods, which is at a point in time.

On October 3, 2019, the Company entered into an Exclusive License Agreement (“ELA” ) pursuant to which it granted an exclusive license for its technology as outlined in the ELA. The ELA is described below. Under the ELA, the Company will receive royalty payments based upon gross revenues earned by the licensee for commercialized products within the field of design and project management platforms for residential use, including single-family residences and multi-family residences, but excluding military housing. The Company has determined that the ELA grants the licensee a right to access the Company’s intellectual property throughout the license period (or its remaining economic life, if shorter), and thus recognizes revenue over time as the licensee recognizes revenue and the Company has the right to payment of royalties. No revenue has been recognized under the ELA for the six months ended June 30, 2021 and 2020. On June 15, 2021, the Company terminated the ELA that was executed on October 3, 2019 which is discussed below.   

CMC Right of First Refusal Agreement – On October 9, 2019, the Company entered into a Right of First Refusal Agreement (the “Agreement”) with CMC Development LLC (“CMC”), which has a term of two (2) years. Under the Agreement, the Company has a right of first refusal with respect to being engaged as a designer and builder of any real estate projects for which CMC has secured the rights to develop and in which CMC has a greater than fifty percent (50%) interest in the owner or developer entity and has the right to select the builder for such real estate project (the “ROFR Rights”). In exchange for such ROFR Rights, the Company agreed to issue to CMC 2,500 shares of restricted stock of the Company’s common stock, of which 1,250 shares vested on March 31, 2021 and the remaining 1,250 shares will vest and be issued on September 30, 2021, unless the Agreement is earlier terminated. In the event that the Agreement is earlier terminated, CMC will still be entitled to receive the entire amount of such restricted stock that has vested as of such earlier termination date, but in no event less than 1,250 shares of such restricted stock. The Agreement also provides for customary indemnification and confidentiality obligations between the parties. The 2,500 shares of restricted stock of the Company's common stock has yet to be issued to CMC. 

The Agreement also provides that CMC has engaged the Company to build and design, in the aggregate, approximately 100 residential and commercial units at 1100 Ridge Avenue, Atlanta, Georgia, which is known as the “Ridge Avenue, Atlanta Project.” The total expected gross revenue to the Company for the project to be derived by CMC is approximately $16,900,000. The project is a residential project but it was not subject to the recently terminated Exclusive License Agreement, dated October 3, 2019. The planning stage of the project was initial delayed due to COVID-19 but the project is still active. No revenue has been recognized under the Agreement for the six months ended June 30, 2021 or 2020. 

The Company entered into a joint venture agreement with Clarity Lab Solutions, LLC (“Clarity Labs”) (the “JV”) in the fourth quarter of 2020. Revenue from the activities of the JV is related to clinical testing services and is recognized when services have been rendered, which is at a point in time.  Included in the consideration the Company expected to be entitled to receive, the Company estimates its contractual allowances, payer denials and price concessions. During the six months ended June 30, 2021, the Company recognized approximately $15,000,000 related to activities through the JV, which is included in medical revenue on the accompanying consolidated statements of operations. In addition, the Company formed Chicago Airport Testing, LLC which is currently collecting rental revenue from subleasing to a consortium of government entities assisting in COVID-19 testing. 

Disaggregation of Revenues

The Company’s revenues are derived from construction and engineering contracts related to Modules, and medical revenue derived from lab testing and test kit sales.

Contract Assets and Contract Liabilities

Accounts receivable are recognized in the period when the Company’s right to consideration is unconditional. Accounts receivable are recognized net of an allowance for credit losses. A considerable amount of judgment is required in assessing the likelihood of realization of receivables.

The timing of revenue recognition may differ from the timing of invoicing to customers. 

Contract assets include unbilled amounts from long-term construction services when revenue recognized under the cost-to-cost measure of progress exceeds the amounts invoiced to customers, as the amounts cannot be billed under the terms of our contracts. Such amounts are recoverable from customers based upon various measures of performance, including achievement of certain milestones, completion of specified units or completion of a contract. Contract assets are generally classified as current within the condensed consolidated balance sheets.  

Contract liabilities from construction and engineering contracts occur when amounts invoiced to customers exceed revenues recognized under the cost-to-cost measure of progress. Contract liabilities additionally include advanced payments from customers on certain contracts. Contract liabilities decrease as the Company recognizes revenue from the satisfaction of the related performance obligation. Contract liabilities are generally classified as current within the condensed consolidated balance sheet. 

Although the Company believes it has established adequate procedures for estimating costs to complete on open contracts, it is at least reasonably possible that additional significant costs could occur on contracts prior to completion. The Company periodically evaluates and revises its estimates and makes adjustments when they are considered necessary.

Deferred Contract Costs - Prior to entering into the ELA, the Company was subject to an agreement to construct and develop a certain property (“Original Agreement”), which now was subject to the ELA. Because of this, the Company is no longer obliged to its Original Agreement. Upon entering the ELA, the Company had an outstanding accounts receivable balance of $306,143, which was forfeited and recognized this amount as deferred contract costs. This amount was offset by $102,217, which was reimbursement from the licensee for project costs on this project.  The Company incurred total deferred contract costs of $203,926.  The Company considered this amount an incremental cost of obtaining that ELA, because the Company expected to recover those costs through future royalty payments. The Company initially planned to amortize the asset over sixty months, which is the initial term of the ELA because the asset relates to the services transferred to the customer during the contract term. As of June 30, 2021, accumulated amortization related to deferred contract costs amounted to $71,374. During the six months ended June 30, 2021 and 2020, amortization expense relating to the deferred contract costs amounted to $20,392 and $20,393, respectively, and is included in general and administrative expenses on the accompanying condensed consolidated statement of operations.  As previously mentioned, the ELA was terminated on June 15, 2021 but the Company expects to recover the deferred contract costs from the Assignment of Limited Rights Under Membership Interest Redemption Agreement, dated June 15, 2021 as described below.  

Exclusive License Agreement – On October 3, 2019, as amended on October 17, 2019, the Company entered into the ELA with CPF GP 2019-1 LLC (the “Licensee”), pursuant to which the Company granted the Licensee an exclusive license (the “License”) solely within the United States and its legal territories to the Company’s technology, intellectual property, any improvements thereto, and any related permits, in order to develop and commercialize products within the field of design and project management platforms for residential use, including single-family residences and multi-family residences, but excluding military housing. The Ridge Avenue Project has also been excluded from the License. The License Agreement had an initial term of five (5) years and was to automatically renew for subsequent five (5) year periods. The License Agreement provided for customary terminating provisions, including the right by the Company to terminate if the Licensee fails to make minimum royalty payments (as described below).

In consideration for the License, during the initial term, the Licensee agreed to pay the Company a royalty of (x) five percent (5%) on the first $20,000,000 of gross revenues derived from the Licensee’s commercialization of the License (net of customary discounts, sales taxes, delivery charges, and amounts for returns) (the “Gross Revenues”), (y) four and one-half percent (4.5%) on the next $30,000,000 of Gross Revenues, and (z) five percent (5%) on all Gross Revenues thereafter (collectively, the “Royalty”) , subject to the following minimum royalty payments determined on a cumulative basis during the initial term: $500,000 in year 1, $750,000 in year 2, $1,500,000 in year 3, $2,000,000 in year 4, and $2,500,000 in year 5. License Agreement provided that if it was extended beyond the initial term, then the parties would negotiate in good faith the royalty rate and the minimum royalty payments for the renewal term(s). In addition, to the extent the Licensee sublicenses any aspect of the License to a sub-licensee, the Licensee was obligated to pay to the Company fifty percent (50%) of all payments received by the Licensee from such sublicensee. The License Agreement also provided that the Company could also provide the Licensee with professional services with respect to the License, and the Licensee was obligated to the Company for employees’ time, materials, and expenses incurred in providing such professional services. The Licensee also separately agreed to reimburse the Company for any third-party expenses incurred by the Company in developing the Company’s remaining and future residential projects. 

The License Agreement provided for customary indemnification obligations between the parties and further provides that the Licensee will indemnify the Company for any claims arising out of the commercialization of the License by the Licensee or any of its subsidiaries, contractors, or sublicensees. In addition, the License Agreement provided that the Company would provide the Licensee with cost estimates for the fabrication and manufacturing of residential projects in the Company’s existing pipeline as of the date of the License Agreement, and if such projects cannot be reasonably constructed and installed at or below such estimates, then the Licensee may withhold payment of any royalty due to the Company under the License Agreement on a dollar-for-dollar basis to offset the costs above the originally estimated amounts.

On June 15, 2021, the Company terminated the Exclusive License Agreement with CPF that the Company had entered into on October 3, 2019.  In connection with the termination, the Company entered into a Settlement and Mutual Release Agreement (the “Settlement Agreement”) with CPF, the general partner (the “Licensee”) of CPF MF 2019-1 LLC (“CPF MF”), and Capital Plus Financial, LLC, a limited partner of the Licensee (“Capital Plus”) and an Assignment of Limited Rights Under Membership Interest Redemption Agreement, dated June 15, 2021, with Capital Plus and the Licensee. In connection with the termination of that certain Exclusive License Agreement, dated as of October 3, 2019 (the “License Agreement”), with the Licensee Pursuant to the Settlement Agreement with CPF and Capital Plus, the License Agreement was terminated, the Company released CPF and CPF MF for any claims in exchange for releases from CPF and Capital Plus and the Company is receiving an assignment of CPF’s right under certain circumstances to a $1.25 million redemption distribution from CPF MF under its Operating Agreement.

Business Combinations

Business Combinations - The Company accounts for business acquisitions using the acquisition method of accounting in accordance with ASC 805 “Business Combinations”, which requires recognition and measurement of all identifiable assets acquired and liabilities assumed at their fair value as of the date control is obtained. The Company determines the fair value of assets acquired and liabilities assumed based upon its best estimates of the acquisition-date fair value of assets acquired and liabilities assumed in the acquisition. Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired. Subsequent adjustments to fair value of any contingent consideration are recorded to the Company’s condensed consolidated statements of operations. Costs that the Company incurs to complete the business combination are charged to general and administrative expenses as they are incurred.

Variable Interest Entities

Variable Interest Entities – The Company accounts for certain legal entities as variable interest entities (“VIE"). When evaluating a VIE for consolidation, the Company must determine whether or not there is a variable interest in the entity. Variable interests are investments or other interests that absorb portions of an entity’s expected losses or receive portions of the entity’s expected returns. If it is determined that the Company does not have a variable interest in the VIE, no further analysis is required and the VIE is not consolidated. If the Company holds a variable interest in a VIE, the Company consolidates the VIE when there is a controlling financial interest in the VIE and therefore are deemed to be the primary beneficiary. The Company is determined to have a controlling financial interest in a VIE when it has both the power to direct the activities of the VIE that most significantly impact the VIE economic performance and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to that VIE. This determination is evaluated periodically as facts and circumstances change.

On August 27, 2020 the Company entered into a joint venture agreement with Clarity Lab Solutions, LLC (“Clarity Labs”) (the “JV”).  In consideration and subject to Clarity Lab’s services and commitments and provided the agreement remains valid and in force, and is not terminated, the Company agreed to issue 200,000 restricted shares of SGB common stock over a defined vesting period starting in December 1, 2020. The restricted shares of SGB common stock were not issued to Clarity Labs as certain capital commitments were not met. Clarity Labs is a licensed clinical laboratory that uses specialized molecular testing equipment and that focuses on the diagnosis and treatment of critical diseases, including COVID-19. Clarity Labs is also engaged in the business of manufacturing, importing and distributions various medical tests. Under the JV, the Company and Clarity Labs will jointly market, sell, and distribute certain products and services (“Clarity Mobile Venture”).  As of June 30, 2021, $381,770 was due to Clarity Labs for expenses paid on behalf of Clarity Mobile Venture, and is included in Due to Affiliates on the accompanying consolidated balance sheets. In addition, during the six months ended June 30, 2021, the Company recognized revenue of $60,110 and other income of $60,000 to Clarity Labs, of which $60,000 is included in accounts receivable as of June 30, 2021. The Company has determined it is the primary beneficiary of Clarity Mobile Venture and has thus consolidated the activities in its condensed consolidated financial statements.

On January 18, 2021 the Company entered into an operating agreement to form CAT. The purpose of CAT is to market, sell, distribute, lease and otherwise commercially exploit certain products and services in the COVID-19 testing industry.  The Company has determined it is the primary beneficiary of CAT and has thus consolidated the activities in its condensed consolidated financial statements.

Investment Entities – On May 31, 2021, the Company's subsidiary SGB Development Corp. agreed to contribute $600,000 to acquire a 50% membership interest in Norman Berry II Owner LLC.  The Company contributed $350,329 of the initial $600,000 in the second quarter of 2021 with the remaining amount being funded in the third quarter of 2021.   The purpose of Norman Berry II Owner LLC is to develop and provide affordable housing in the Atlanta, Georgia metropolitan area.  The Company has determined it is not the primary beneficiary of "Norman Berry" and thus will not consolidate the activities in its condensed consolidated financial statements. The Company will use the equity method to report the activities as an investment in on its condensed consolidated financial statements. 

On June 24, 2021, the Company's subsidiary SGB Development Corp. entered into an operating agreement with Jacoby Development for a 10% non-dilutable equity interest for JDI-Cumberland Inlet, LLC.  The Company contributed $3,000,000 for its 10% equity interest.  The purpose of JDI-Cumberland Inlet, LLC is to develop a waterfront parcel in a mixed-use destination community.  The Company has determined it is not the primary beneficiary of JDI-Cumberland Inlet, LLC and thus will not consolidate the activities in its condensed consolidated financial statements.  The Company will use the equity method to report the activities as an investment in on its condensed consolidated financial statements.  

Cash and cash equivalents

Cash and cash equivalents – The Company considers cash and cash equivalents to include all short-term, highly liquid investments that are readily convertible to known amounts of cash and have original maturities of three months or less upon acquisition. Cash and cash equivalents totaled $2,323,599 as of June 30, 2021 and $13,010,356 as of December 31, 2020. 

Short-term investment

Short-term investment – The Company classifies investments consisting of a certificate of deposit with a maturity greater than three months but less than one year as short-term investment.  The Company had no short-term investment as of June 30, 2021 or December 31, 2020, respectively.   

Accounts receivable and allowance for credit losses

Accounts receivable and allowance for credit losses – Accounts receivable are receivables generated from sales to customers and progress billings on performance type contracts. Amounts included in accounts receivable are deemed to be collectible within the Company’s operating cycle. The Company recognizes accounts receivable at invoiced amounts. 

The allowance for credit losses reflects the Company's best estimate of expected losses inherent in the accounts receivable balances. Management provides an allowance for credit losses based on the Company’s historical losses, specific customer circumstances, and general economic conditions. Periodically, management reviews accounts receivable and adjusts the allowance based on current circumstances and charges off uncollectible receivables when all attempts to collect have been exhausted and the prospects for recovery are remote. Recoveries are recognized when they are received. Actual collection losses may differ from our estimates and could be material to our condensed consolidated financial position, results of operations, and cash flows. 

Inventory

Inventory – Raw construction materials (primarily shipping containers and fabrication materials) are valued at the lower of cost (first-in, first-out method) or net realizable value. Finished goods and work-in-process inventories are valued at the lower of cost or net realizable value, using the specific identification method. Medical equipment and COVID-19 test and testing supplies are valued at the lower of cost, (first-in, first-out method) or net realizable value. As of June 30, 2021 there was inventory of $4,429 for construction materials, and $1,405,486 of medical equipment and COVID-19 test and testing supplies. As of December 31, 2020 there was inventory of $4,429 for construction materials, and $773,715 of medical equipment and COVID-19 test and testing supplies. 

Goodwill

Goodwill – The Company performs its impairment test of goodwill at the reporting unit level each fiscal year, or more frequently if events or circumstances change that would more likely than not reduce the fair value of its reporting unit below its carrying values. The Company performs a goodwill impairment test by comparing the fair value of the reporting unit with its carrying value and recognizes an impairment charge for the amount by which the carrying value exceeds the fair value, not to exceed the total amount of goodwill. The amount by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss. There were no impairments during the year ended December 31, 2020 or the six months ended June 30, 2021 and 2020. The Company has taken the recent COVID-19 pandemic into consideration when determining impairment. 

Intangible assets

Intangible assets – Intangible assets consist of $2,766,000 of proprietary knowledge and technology, which is being amortized over 20 years. In addition, $97,164 of trademarks, and $47,800 of website costs are being amortized over 5 years.  The Company evaluated intangible assets for impairment during the year ended December 31, 2020, and determined that there were no impairment losses. There was no impairment during the six months ended June 30, 2021 and 2020. The accumulated amortization as of June 30, 2021 and 2020 was $732,085 and $1,686,876, respectively. The amortization expense for the six months ended June 30, 2021 and 2020 was $82,230 and $72,561, respectively. The amortization expense for the three months ended June 30, 2021 and 2020 was $41,823 and $36,281, respectively. The estimated amortization expense for the successive five years is as follows:  

For the year ending December 31,:
2021	$	83,646
2022		162,970
2023		161,176
2024		160,469
2025		157,051
Thereafter		1,453,567
	$	2,178,879

Property, plant and equipment

Property, plant and equipment – Property, plant and equipment is stated at cost. Depreciation is computed using the straight-line method over the estimated lives of each asset. Estimated useful lives for significant classes of assets are as follows: computer and software 3 to 5 years, furniture and other equipment 5 to 7 years, automobiles 2 to 5 years, buildings held for lease 5 to 7 years, and equipment 5 to 29 years. Repairs and maintenance are charged to expense when incurred.

Convertible instruments

Convertible instruments – The Company bifurcates conversion options from their host instruments and accounts for them as free standing derivative financial instruments according to certain criteria. The criteria include circumstances in which (a) the economic characteristics and risks of the embedded derivative instrument are not clearly and closely related to the economic characteristics and risks of the host contract, (b) the hybrid instrument that embodies both the embedded derivative instrument and the host contract is not re-measured at fair value under otherwise applicable generally accepted accounting principles with changes in fair value reported in earnings as they occur and (c) a separate instrument with the same terms as the embedded derivative instrument would be considered a derivative instrument.

Common stock purchase warrants and other derivative financial instruments

Common stock purchase warrants and other derivative financial instruments – The Company classifies as equity any contracts that (i) require physical settlement or net-share settlement or (ii) provides a choice of net-cash settlement or settlement in the Company’s own shares (physical settlement or net-share settlement) providing that such contracts are indexed to the Company’s own stock. The Company classifies as assets or liabilities any contracts that (i) require net-cash settlement (including a requirement to net cash settle the contract if any event occurs and if that event is outside the Company’s control) or (ii) gives the counterparty a choice of net-cash settlement or settlement shares (physical settlement or net-cash settlement). The Company assesses classification of common stock purchase warrants and other free standing derivatives at each reporting date to determine whether a change in classification between assets and liabilities or equity is required.

Fair value measurements

Fair value measurements – Financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities are carried at cost, which the Company believes approximates fair value due to the short-term nature of these instruments.

The Company measures the fair value of financial assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value.

The Company uses three levels of inputs that may be used to measure fair value:

Level 1	Quoted prices in active markets for identical assets or liabilities.
Level 2	Quoted prices for similar assets and liabilities in active markets or inputs that are observable.
Level 3	Inputs that are unobservable (for example, cash flow modeling inputs based on assumptions).

Transfer into and transfers out of the hierarchy levels are recognized as if they had taken place at the end of the reporting period. 

Share-based payments

Share-based payments – The Company measures the cost of services received in exchange for an award of equity instruments based on the fair value of the award. For employees and directors, including non-employee directors, the fair value of a stock option award is measured on the grant date. The fair value amount is then recognized over the period services are required to be provided in exchange for the award, usually the vesting period. The Company recognizes stock-based compensation expense on a graded-vesting basis over the requisite service period for each separately vesting tranche of each award. Stock-based compensation expense to employees and all directors are reported within payroll and related expenses in the consolidated statements of operations. Stock-based compensation expense to non-employees is reported within marketing and business development expense in the condensed consolidated statements of operations.   

Income taxes

Income taxes – The Company accounts for income taxes utilizing the asset and liability approach. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes generally represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from the differences between the financial and tax bases of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted.

The calculation of tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company recognizes liabilities for anticipated tax audit issues based on the Company’s estimate of whether, and the extent to which, additional taxes will be due. If payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when the liabilities are no longer determined to be necessary. If the estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result.

Concentrations of credit risk

Concentrations of credit risk – Financial instruments, that potentially subject the Company to concentration of credit risk, consist principally of cash and cash equivalents. The Company places its cash with high credit quality institutions. At times, such amounts may be in excess of the FDIC insurance limits. The Company has not experienced any losses in such account and believes that it is not exposed to any significant credit risk on the account.

With respect to receivables, concentrations of credit risk are limited to a few customers in the construction industry. The Company performs ongoing credit evaluations of its customers’ financial condition and, generally, requires no collateral from its customers other than normal lien rights. At June 30, 2021 and December 31, 2020, 62% and 79%, respectively, of the Company’s gross accounts receivable in excess of 10% were due from two and three customers. 

Revenue in excess of 10% relating to one and two customers represented approximately 77% and 72% of the Company's total revenue for the three months ended June 30, 2021 and 2020, respectively. Revenue relating to one and three customers represented approximately 71% and 69% of the Company's total revenue for the six months ended June 30, 2021 and 2020, respectively.

Cost of revenue in excess of 10% relating to three and two vendors represented approximately 52% and 51% of the Company’s total cost of revenue for the three months ended June 30, 2021 and 2020, respectively. Cost of revenue relating to three and four vendors represented approximately 48% and 75% of the Company’s total cost of revenue for the six months ended June 30, 2021 and 2020, respectively. The Company believes it has access to alternative suppliers, with limited disruption to the business, should circumstances change with its existing suppliers.
