Notes to Condensed Consolidated Financial Statements

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 Company provides two main products, both of which are used to meet the growing demand for safe and green commercial, industrial and residential building construction. The Company provides SGBlocks_^TM, code engineered cargo shipping containers that the Company modifies for use in construction. Rather than consuming new steel and lumber, SGBlocks^TM capitalize on the structural engineering and design parameters a shipping container must meet and repurposes them for use in building. They offer the construction industry a safer, greener, faster, longer lasting and more economical alternative to conventional construction methods. The Company also provides purpose-built modules (“SGPBMs” and, together with SGBlocks^TM, “Modules”), which are prefabricated steel modular units created specifically for use in modular construction, unlike the shipping containers used to create SGBlocks_^TM.  

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

2. Liquidity 

The Company has prepared its condensed consolidated financial statements on a going concern basis, which assumes that the Company will realize its assets and satisfy its liabilities in the normal course of business. However, the Company has incurred net losses since its inception and has negative operating cash flows, which raise substantial doubt about its ability to continue as a going concern. The accompanying financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from the outcome of the uncertainty concerning the Company’s ability to continue as a going concern.

As of March 31, 2019, the Company had cash and cash equivalents of $250,464 and a backlog of $95.8 million. See Note 8 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: 

	2019
Within 1 year	$	20,847,051
1 to 2 years		54,546,876
Thereafter		20,445,913
Total Backlog	$	95,839,840

Based on the expected conversion timeline of its backlog, the Company expects to generate positive cash flows from operations for the year ending December 31, 2019. 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 by containing costs and entering into strategic alliances, as well as exploring other options, including the possibility of raising additional debt or equity capital as necessary. The Company completed an equity offering in April 2019, which resulted in net proceeds of approximately $692,248. See Note 13 for a discussion of the offering. 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.

3. Summary of Significant Accounting Policies

Basis of presentation and principals of consolidation – The accompanying unaudited condensed consolidated 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 Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for annual financial statements. The condensed consolidated financial statements and notes should be read in conjunction with the financial statements and notes for the year ended December 31, 2018 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, as filed with the Securities and Exchange Commission on March 29, 2019. 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 three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019.

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, SG Building Blocks, Inc. and SG Residential, Inc. All significant intercompany accounts and transactions have been eliminated. Certain prior period amounts have been reclassified to conform to the current period’s presentation.

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

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The update’s principal objective is to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet. ASU 2016-02 continues to retain a distinction between finance and operating leases but requires lessees to recognize a right-of-use asset representing their right to use the underlying asset for the lease term and a corresponding lease liability on the balance sheet for all leases with terms greater than twelve months. The update is effective for fiscal years beginning after December 15, 2018. In July 2018, the FASB issued ASU No. 2018-11, “Leases (Topic 842): Targeted Improvements” (“ASU 2018-11”), which provides entities with an additional transition method. Under ASU 2018-11, entities have the option of recognizing the cumulative effect of applying the new standard as an adjustment to beginning retained earnings in the year of adoption while continuing to present all prior periods under previous lease accounting guidance. In July 2018, the FASB also issued ASU No. 2018-10, “Codification Improvements to Topic 842, Leases” (“ASU 2018-10”), which clarifies how to apply certain aspects of ASU 2016-02. The Company adopted ASU 2016-02, ASU 2018-10 and ASU 2018-11 effective January 1, 2019. The Company had no operating or finance lease agreements as of March 31, 2019. The adoption of ASU No. 2016-02 did not have a material impact on the Company’s financial statements and disclosures. 

In June 2018, the FASB issued ASU No. 2018-07, “Compensation — Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting” (“ASU 2018-07”), which expands the scope of Topic 718 to include all share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 specifies that Topic 718 applies to all share-based payment transactions in which the grantor acquires goods and services to be used or consumed in its own operations by issuing share-based payment awards. Under ASC 718, the measurement date for equity-classified, share-based awards is generally the grant date of the award. ASU 2018-07 also clarifies that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under ASC 606. The Company adopted ASU 2018-07 effective January 1, 2019. The adoption provides administrative relief by fixing the remaining unamortized expense of the award and eliminating the requirement to quarterly re-measure the Company’s nonemployee awards. The adoption of ASU No. 2018-07 did not have a material impact on the Company’s financial statements and disclosures.

3. Summary of Significant Accounting Policies (continued)

Recently issued accounting pronouncements not yet adopted – New accounting pronouncements requiring implementation in future periods are discussed below. 

In January 2017, the FASB issued ASU No. 2017-04, “Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”), to simplify the test for goodwill impairment by removing Step 2. An entity will, therefore, perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the fair value, not to exceed the total amount of goodwill allocated to the reporting unit. An entity still has the option to perform a qualitative assessment to determine if the quantitative impairment test is necessary. The ASU is effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted. Adoption of the ASU is on a prospective basis. Based on current evaluation, the Company does not expect that ASU No. 2017-04 will have a material impact on the Company’s financial statements.

In August 2018, the FASB issued ASU No. 2018-13, “Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”). This ASU amends ASC 820 to add, remove and modify certain disclosure requirements for fair value measurements. For example, public companies will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU 2018-13 is effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. Management does not expect the adoption of ASU 2018-13 to have a material impact on the Company’s financial position, results of operations or cash flow.

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 and allowance for doubtful accounts. 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 current and long-term 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.

3. Summary of Significant Accounting Policies (continued)

Revenue recognition – 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). 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

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. 

Disaggregation of Revenues

The Company’s revenues are principally derived from construction and engineering contracts related to Modules. Our contracts are with many different customers in numerous industries.

The following tables provide further disaggregation of the Company’s revenues by categories:

3. Summary of Significant Accounting Policies (continued)

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 doubtful accounts. 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 and labeled as “costs and estimated earnings in excess of billings on uncompleted contracts”.

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 and labeled as “billings in excess of costs and estimated earnings on uncompleted contracts”.

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.

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 $250,464 as of March 31, 2019 and $1,368,395 as of December 31, 2018. 

Short-term investment – The Company classifies any investment with a maturity greater than three months but less than one year as short-term investment.  The Company had no short-term investments as of March 31, 2019 or December 31, 2018.

Accounts receivable and allowance for doubtful accounts – 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 account receivable at invoiced amounts. 

The allowance for doubtful accounts reflects the Company's best estimate of probable losses inherent in the accounts receivable balances. Management provides an allowance for doubtful accounts 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 the Company’s estimates and could be material to its consolidated financial position, result of operations, and cash flows.

3. Summary of Significant Accounting Policies (continued)

Inventory – Raw construction materials (primarily shipping containers) 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. There was no inventory as of March 31, 2019 or December 31, 2018.

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 first assesses qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount, including goodwill. If management concludes that it is more likely than not that the fair value of the reporting unit is less than its carrying amount, management conducts a two-step quantitative goodwill impairment test. The first step of the impairment test involves comparing the fair value of the applicable reporting unit with its carrying value. If the carrying amount of the reporting unit exceeds the reporting unit’s fair value, management performs the second step of the goodwill impairment test. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit’s goodwill with the carrying value of that goodwill. The amount by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss. The Company’s evaluation of goodwill completed during the year ended December 31, 2018 resulted in no impairment losses.

Intangible assets – Intangible assets represent the preliminary assets identified upon emergence from bankruptcy and consist of $2,766,000 of proprietary knowledge and technology which is being amortized over 20 years and $1,113,000 of customer contracts which was being amortized over 2.5 years. In addition, intangible assets include $28,820 of trademarks and $5,300 of website costs which are being amortized over 5 years. The Company evaluated intangible assets for impairment during the year ended December 31, 2018, and determined that there were no impairment losses. The accumulated amortization as of March 31, 2019 and 2018 was $1,505,472 and $1,026,889, respectively. The amortization expense for the three months ended March 31, 2019 and 2018 was $36,281 and $147,316, respectively. The estimated amortization expense for the successive five years is as follows:

For the year ended December 31,
2019	$	108,843
2020		145,124
2021		145,124
2022		140,801
2023		139,007
Thereafter		1,728,749
	$	2,407,648

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 life for significant classes of assets are as follows: computer and software 3 to 5 years and equipment 5 to 7 years. Repairs and maintenance are charged to expense when incurred.

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.

3. Summary of Significant Accounting Policies (continued)

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).

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 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. 

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 its 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 March 31, 2019 and December 31, 2018, 72% and 76%, respectively, of the Company’s accounts receivable were due from two customers.

Revenue relating to two and three customers represented approximately 89% and 80% of the Company’s total revenue for the three months ended March 31, 2019 and 2018, respectively.

Cost of revenue relating to two and three vendors represented approximately 95% and 75% of the Company’s total cost of revenue for the three months ended March 31, 2019 and 2018, 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 March 31, 2019 and December 31, 2018, the Company’s accounts receivable consisted of the following: 

	March 31, 2019			December 31, 2018
Billed:
Block sales	$	—		$	14,723
Construction services		2,826,999			1,619,498
Engineering services		416,894			400,877

Total gross receivables		3,796,509			2,586,221
Less: allowance for doubtful accounts (1)		(839,895	)		(839,895	)
Total net receivables	$	2,956,614		$	1,746,326
(1) The allowance for doubtful accounts is primarily due to unpaid billings on a contract that is currently in dispute.

Receivables are evaluated for collectability and allowances for potential losses are established or maintained on applicable receivables. The allowance for doubtful accounts was $839,895 as of March 31, 2019. There was no provision for doubtful accounts and no write offs for the three months ended March 31, 2019. The provision for doubtful accounts was $810,580 and write offs were $4,920 for the year ended December 31, 2018.   

5. Contract Assets and Contract Liabilities 

Costs and estimated earnings on uncompleted contracts consisted of the following at March 31, 2019 and December 31, 2018:

	March 31,  2019			December 31, 2018
Costs incurred on uncompleted contracts	$	11,175,706		$	11,307,975
Estimated earnings to date on uncompleted contracts		1,032,413			838,615
Gross contract assets		12,208,119			12,146,590
Less: billings to date		(13,776,176	)		(13,221,152	)
Net contract assets (liabilities)	$	(1,568,057	)	$	(1,074,562	)

The above amounts are included in the accompanying consolidated balance sheets under the following captions at March 31, 2019 and 2018:

	March 31,  2019			December 31, 2018
Costs and estimated earnings in excess of billings on uncompleted contracts	$	12,424		$	260,325
Billings in excess of costs and estimated earnings on uncompleted contracts		(1,580,481	)		(1,334,887	)
Net contract assets (liabilities)	$	(1,568,057	)	$	(1,074,562	)

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.

6. Property, Plant and Equipment

Property, plant and equipment are stated at cost less accumulated depreciation and amortization and depreciated using the straight-line method over their useful lives. At March 31, 2019 and December 31, 2018, the Company’s property, plant and equipment, net consisted of the following:

	March 31, 2019			December 31, 2018
Computer equipment and software	$	39,193		$	39,193
Furniture and other equipment		63,479			63,479
Property, plant and equipment		102,672			102,672
Less: accumulated depreciation		(34,500	)		(31,335	)
Property, plant and equipment, net	$	68,172		$	71,337

Depreciation expense for the three months ended March 31, 2019 and 2018 amounted to $3,165 and $931, respectively. 

7. 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 March 31, 2019, there were options, including options granted to non-employees and non-directors, restricted stock units and warrants to purchase 1,080,059, 346,936 and 86,250 shares of common stock, respectively, outstanding that could potentially dilute future net income (loss) per share. Because the Company had a net loss for the three months ended March 31, 2019, 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 March 31, 2018, there were options, including options to non-employees and non-directors, and warrants to purchase 1,188,392 and 86,250 shares of common stock, respectively, outstanding that could potentially dilute future net income (loss) per share.

8. Construction Backlog

The following represents the backlog of signed construction and engineering contracts in existence at March 31, 2019 and December 31, 2018, 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 March 31, 2019 and December 31, 2018, respectively, on which work has not yet begun:

	March 31, 2019			December 31, 2018
Balance - beginning of period	$	97,657,379		$	76,659,029
New contracts and change orders during the period		(82,415	)		29,189,062
Subtotal		97,574,964			105,848,091
Less: contract revenue earned during the period		(1,735,124	)		(8,190,712	)
Balance - end of period	$	95,839,840		$	97,657,379

Backlog at March 31, 2019 included two large contracts entered into by the Company during the third quarter of 2017 and one contract during the last quarter of 2018 in the amounts of approximately $55 million, $15 million and $25 million, respectively. The Company expects that all of this revenue will be realized by June 30, 2021. During the fourth quarter of 2018, the Company moved a contract of $27.5 million out of backlog and into its pipeline until the customer completes a highest and best use analysis of the land. 

The Company’s remaining backlog as of March 31, 2019 represents the remaining transaction price of firm contracts for which work has not been performed and excludes unexercised contract options.  As of March 31, 2019, the aggregate amount of the transaction price allocated to backlog was $95,839,840.

The Company expects to satisfy its backlog which represents the remaining unsatisfied performance obligation on contracts as of March 31, 2019 over the following period:

	2019
Within 1 year	$	20,847,051
1 to 2 years		54,546,876
Thereafter		20,445,913
Total Backlog	$	95,839,840

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.

9. Stockholders’ Equity

Public Offering – In June 2017, the Company issued 1,500,000 shares of its common stock at $5.00 per share through a public offering (the “Public Offering”). The Company incurred $1,388,615 in issuance costs from the Public Offering and issued 75,000 warrants valued at $55,475 to the underwriters (as discussed in Note 10).

In July 2017, as permitted by the underwriting agreement entered into in connection with the Public Offering, the underwriters exercised their option to purchase an additional 225,000 shares of common stock at $5.00 per share. The Company incurred $176,771 in issuance costs from this issuance. In connection with this exercise, certain affiliates of the underwriters were granted additional warrants to purchase 11,250 shares of common stock in the aggregate valued at $8,321 (as discussed in Note 10). 

In connection with and prior to the Public Offering, the Company issued 1,801,670 shares of its common stock upon conversion of all outstanding preferred stock and 516,667 shares of its common stock upon conversion of the previously outstanding convertible debentures.

Issuance of Common Stock – In accordance with the Advisory Agreement (as defined below), a consultant was issued 50,000 shares of the Company’s common stock for services that were required to be performed by November 30, 2017. The fair market value of these shares amounted to $254,500 as of November 30, 2017, which was expensed as general and administrative expenses.  

10. Warrants  

In conjunction with the Public Offering, the Company issued to certain affiliates of the underwriters, as compensation, warrants to purchase an aggregate of 86,250 shares of common stock at an exercise price of $6.25 per share. The warrants are exercisable at the option of the holder on or after June 21, 2018 and expire June 21, 2023. The fair value of warrants was calculated utilizing a Black-Scholes model and amounted to $63,796. The fair market value of the warrants as of the date of issuance has been included in issuance costs in additional paid-in capital.

11. Share-based Compensation 

On October 26, 2016, the Company’s Board of Directors approved the issuance of up to 500,000 shares of the Company’s common stock in the form of restricted stock or options (“2016 Stock Plan”). Effective January 20, 2017, the 2016 Stock Plan was amended and restated as the SG Blocks, Inc. Stock Incentive Plan, as further amended effective June 1, 2018 (the “Incentive Plan”). The Incentive Plan authorizes the issuance of up to 2,500,000 shares of common stock. It authorizes the issuance of equity-based awards in the form of stock options, stock appreciation rights, restricted shares, restricted share units, other share-based awards and cash-based awards  to non-employee directors and to officers, employees and consultants of the Company and its subsidiaries, except that incentive stock options may only be granted to the Company’s employees and its subsidiary’s employees. The Incentive Plan expires on October 26, 2026, and is administered by the Compensation Committee of the Board of Directors of the Company. Each of the Company’s employees, directors, and consultants are eligible to participate in the Incentive Plan. As of March 31, 2019, there were 1,020,202 shares of common stock available for issuance under the Incentive Plan.

11. Share-based Compensation (continued)

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 three months ended March 31, 2019. The table includes options granted to employees and directors of the Company, 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
Outstanding – December 31, 2018		1,105,059		$	1.24	$	4.06		8.41	$	—
Granted		—			—		—
Exercised		—			—		—
Cancelled		(25,000	)		—		—
Outstanding – March 31, 2019		1,080,059			1.24		4.05		8.15	$	—
Exercisable – December 31, 2018		949,355			1.23		4.00		8.30		—
Exercisable – March 31, 2019		970,190		$	1.23	$	4.01		8.07	$	—

For the three months ended March 31, 2019 and 2018, the Company recognized stock-based compensation expense of $32,098 and $79,989, respectively, related to stock options. This expense is included in payroll and related expenses in the accompanying consolidated statements of operations.

As of March 31, 2019, there was $131,815 of total unrecognized compensation costs related to non-vested stock options, which will be expensed over a weighted average period of one year. The intrinsic value is calculated as the difference between the fair value of the stock price at year end and the exercise price of each of the outstanding stock options. The fair value of the stock price at March 31, 2019 was $1.84 per share.

In March 2018, the Company granted Mr. Galvin, Mr. Shetty and six employees of the Company options to purchase 82,154, 81,342 and an aggregate of 86,504, respectively, shares of the Company’s common stock with an exercise price of $4.61 per share. These options vest in equal quarterly installments over either a two-year and three-year period and will fully vest by the end of March 31, 2021. The options with a two-year period, which includes those granted to Mr. Galvin and Mr. Shetty, will vest in full by December 31, 2019; the options with a three-year vesting period will vest in full by March 31, 2021. The fair value of these options upon issuance amounted to $320,000.

Non-Employee Stock Options 

In September 2017, in connection with an advisory agreement entered into by the Company (the “Advisory Agreement”), a consultant was granted options to purchase 50,000 shares of the Company’s common stock, with an exercise price of $6.25. The options were scheduled to vest when certain performance conditions were met. These performance conditions consisted of the purchase of fifty modular units from the Company by qualified customers. As of March 31, 2019, the required performance conditions were not met, and the options expired.

Restricted stock units granted to Mr. Galvin, Mr. Armstrong, Mr. Shetty, and an aggregate of six employees and one consultant of 122,785, 15,432, 114,575 and an aggregate of 61,266, respectively, vest in installments over either a one-year, two-year, three-year and four-year period and will fully vest by the end of December 31, 2022. The fair value of these units upon issuance amounted to $847,957.  

On January 15, 2019 and February 26, 2019, a total of 10,514 of restricted stock units were granted to two of the Company’s non-employee directors, under the Incentive Plan, at the calculated fair value of $2.94 and $2.76 per share, which represents the average closing price of the Company’s common stock for the ten trading days immediately preceding and including the grant date. The restricted stock units granted on January 15, 2019 will vest on January 15, 2020, subject to each individual’s continued service as a director of the Company through such date, and are payable six months after the termination of the director from the Company’s Board of Directors or death or disability. The restricted stock units granted on February 26, 2019 vest on the earlier of (A) the first anniversary of the date of the grant or (B) the date of the 2019 annual meeting of the Company’s stockholders subject to each individual’s continued service as a director of the Company through such date, and are payable six months after the termination of the director from the Board of Directors or death or disability.

For the three months ended March 31, 2019 and 2018, the Company recognized stock-based compensation expense of $130,395 and $0 related to restricted stock units. This expense is included in the payroll and related expenses in the accompanying condensed consolidated statement of operations. For the three months ended March 31, 2019 and 2018, the Company recognized $54,315 and $0 related to restricted stock units in lieu of accrued compensation.

12.  Commitments and Contingencies  

Legal Proceedings

The Company is subject to certain claims and lawsuits arising in the normal course of business. The Company assesses its 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 its 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 to the Company, advice of counsel, and available insurance coverage, the Company believes that its established accruals are adequate and the liabilities arising from the legal proceedings will not have a material adverse effect on its consolidated financial condition. The Company notes, 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 Company’s results of operations for a particular period, depending upon the size of the loss or the Company’s 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 President, 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.

The claims against the Company arise from an Assignment Agreement, dated as of May 30, 2018, between Pizzarotti, Phipps and the Company (the “Assignment Agreement”), pursuant to which the Company intended to provide a letter of credit in exchange for an assignment of the proceeds from certain subcontracted work to be provided by Phipps to Pizzarotti. The Assignment Agreement was ultimately terminated, and the Company returned all payments to Phipps. Notwithstanding the above, Pizzarotti has sued seeking damages for nonperformance of the sub-contracted work and the return of a $500,000 payment from Phipps.

The Company believes that the Assignment Agreement was properly terminated and believes that the claims brought against the Company and Mr. Shetty have no merit. The Company intends to vigorously defend the litigation.

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.

Vendor Litigation – On January 1, 2019, SG Blocks filed a suit against Teton Buildings, LLC (“Teton”) to recover breach of contract damages of approximately $2,100,000 plus attorneys’ fees related to the HOLA Community Partners construction project in Los Angeles, California (the “HOLA Project”), for which Teton was engaged by the Company to supply modular units in early 2017. The Company’s complaint alleged that Teton failed to comply with specific product requirements with respect to the modular units for the HOLA Project and that Teton’s delay and product quality resulted in damages. The Company’s claims include breach of contract, negligence, and breach of express warranty. The lawsuit was filed as SG Blocks, Inc. v. Teton Buildings, LLC; Case Number 2019-02827 in the United States District Court for the Southern District of Texas. 

SG Blocks believes it will prevail on the merits of the case. As with any litigation at this early stage, the cost of litigating and the outcome remain uncertain.

12. Commitments and Contingencies (continued)

HOLA Community Partners Matter – There is an ongoing dispute between the Company and HOLA Community Partners, a California non-profit corporation, in connection with the parties’ Construction and Delivery Agreement, dated June 1, 2017, pursuant to which HOLA Community Partners hired the Company for design, engineering, fabrication, and installation services for the construction of the HOLA Project. The Company claims that HOLA Community Partners owes the Company certain amounts due for work performed on the HOLA Project and extra costs incurred due to delays and impacts caused by HOLA Community Partners. HOLA Community Partners disputes the amounts owed, and claims that the Company failed to meet its contractual obligations. The parties are in ongoing settlement discussions. Neither party has commenced litigation as of the date of these condensed consolidated financial statements. 

In addition, the Company is subject to other routine legal proceedings, claims, and litigation in the ordinary course of its business. Defending lawsuits requires significant management attention and financial resources and the outcome of any litigation, including the matters described above, is inherently uncertain. The Company does not, however, currently expect that the costs to resolve these routine matters will have a material adverse effect on its consolidated financial position, results of operations, or cash flows.

13. Subsequent Events

On April 25, 2019, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with certain institutional investors (the “Investors”) for the sale by the Company of 847,750 shares (the “Common Shares”) of the Company’s common stock, at a purchase price of $1.10 per share. Concurrently with the sale of the Common Shares, pursuant to the Purchase Agreement, the Company also sold common stock purchase warrants to such Investors to purchase up to an aggregate of 847,750 shares of common stock (the “Warrants”). The Company sold the Common Shares and Warrants for aggregate gross proceeds of approximately $932,525. Subject to certain beneficial ownership limitations, the Warrants will be initially exercisable on the six-month anniversary of the issuance date at an exercise price of $1.375 per share, subject to adjustments as provided under the terms of the Warrants, and include a floor in the provision on voluntary adjustments to the then-current exercise price. The Warrants are exercisable for five years from the initial exercise date. The closing of the sales of these securities under the Purchase Agreement occurred on April 29, 2019.

The estimated net proceeds from the transactions were approximately $692,248 after deducting certain fees due to the placement agent, discussed below, and the Company’s estimated transaction expenses. The net proceeds will be used for working capital purposes. The Common Shares were offered and sold by the Company pursuant to an effective shelf registration statement on Form S-3, which was filed with the Securities and Exchange Commission (the “SEC”) on December 18, 2018 and subsequently declared effective on February 7, 2019 (File No. 333-228882), and the base prospectus contained therein. The Company filed a prospectus supplement with the SEC in connection with the sale of the Common Shares.

The Warrants and the shares issuable upon exercise of the Warrants were sold without registration under the Securities Act of 1933, as amended (the “Securities Act”), in reliance on the exemptions provided by Section 4(a)(2) of the Securities Act as transactions not involving a public offering and Rule 506 promulgated under the Securities Act as sales to accredited investors, and in reliance on similar exemptions under applicable state laws.

In connection with the transactions described above, the Company entered into a placement agency agreement (the “Placement Agency Agreement”) with Roth Capital Partners, LLC (“Roth”), pursuant to which Roth agreed to serve as exclusive placement agent for the issuance and sale of the Common Shares and Warrants. The Company agreed to pay Roth an aggregate fee equal to 7.0% of the gross proceeds received by the Company from the sale of the securities in the transactions. Pursuant to the Placement Agency Agreement, the Company also agreed to grant to Roth or its designees warrants to purchase up to 10% of the aggregate number of shares of Common Stock sold in the transactions, or 84,775 shares (the “Roth Warrants”), which Roth Warrants shall be issued in two series of warrants (50% of the Roth Warrants in each series) and the second series of warrants shall vest ratably upon the exercise of the first series of warrants. The Roth Warrants have substantially the same terms as the Warrants, except that the Roth Warrants have an expiration date of April 25, 2024. The Roth Warrants and the shares issuable upon exercise of the Roth Warrants were issued in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act as transactions not involving a public offering and in reliance on similar exemptions under applicable state laws. The Company also agreed to reimburse Roth for $50,000 of its expenses incurred by it in connection with the offering.

Background

We are one of the leading design and construction services firms using code-engineered cargo shipping containers for safe and sustainable construction. We offer the construction industry a safer, greener, faster, longer-lasting and more economical alternative to conventional construction methods. We redesign, repurpose and convert heavy-gauge steel cargo shipping containers into SGBlocks™, which are safe green building blocks for commercial, industrial and residential building construction.  

We fabricate modules for construction of buildings using either SGBlocks™, which are modified cargo shipping containers for use in construction, or SGPBMs, which are prefabricated steel modular units customized for use in modular construction primarily to augment or complement a SGBlocks™ structure.

When using SGBlocks™, we take existing steel shipping containers and repurpose them into modules that can be stacked, arranged, or configured to fit most structural applications. The use of these repurposed shipping containers allows architects, builders, and owners more design flexibility and greater construction efficiency than traditional methods of construction. SGBlocks™ also have a particular application in meeting safe, affordable and sustainable housing needs, especially in hurricane- and earthquake-prone areas.

When using SGPBMs, we customize an engineered steel structure to meet customer design and specifications, primarily to augment or complement a SGBlocks™ structure.

Results of Operations

Three Months Ended March 31, 2019 and 2018:

	Three Months Ended March 31, 2019			Three Months Ended March 31, 2018
Revenue	$	1,735,124		$	1,543,526
Cost of revenue		(1,191,019	)		(1,379,930	)
Operating expenses		(1,034,840	)		(917,704	)
Operating loss		(490,735	)		(754,108	)
Other income (expense)		—			4
Net loss	$	(490,735	)	$	(754,104	)

Revenue

Total revenue for the three months ended March 31, 2019 was $1,735,124 compared to $1,543,526 for the three months ended March 31, 2018. This increase of $191,598 or 12% was mainly driven by growth in the Company’s retail and office contracts that were in progress or completed for the three months ended March 31, 2019 as compared to March 31, 2018. Revenue resulting from the Company's retail and office contracts increased by approximately $1,177,689, which was offset by a decrease in revenue from the Company’s school and special use contracts of $1,058,141.   

25

Cost of Revenue and Gross Profit

Cost of revenue was $1,191,019 for the three months ended March 31, 2019 compared to $1,379,930 for the three months ended March 31, 2018. The decrease of $188,911 is primarily related to the lower cost of buying and modifying containers. 

Gross profit was $544,105 and $163,596 for the three months ended March 31, 2019 and 2018, respectively.   

Gross profit percentage increased to 31% for the three months ended March 31, 2019 compared to 11% for the three months ended March 31, 2018 primarily due to lower margins in the three months ended March 31, 2018 from a legacy contract.

Payroll and Related Expenses

Payroll and related expenses for the three months ended March 31, 2019 were $638,550 compared to $405,418 for the three months ended March 31, 2018. This increase was primarily caused by an increase in salaries and additional head count of $129,472 and an increase in stock-based compensation expense of $82,504 recognized during the three months ended March 31, 2019 compared to the three months ended March 31, 2018. We recognized $162,493 in stock-based compensation expense for the three months ended March 31, 2019, compared to $79,989 for March 31, 2018.

Other Operating Expenses

Other operating expenses for the three months ended March 31, 2019 were $396,290 compared to $512,286 for the three months ended March 31, 2018. The decrease resulted primarily from decreases in marketing and business development costs of approximately $33,000, a decrease of  approximately $111,000 in amortization expense caused by customer contracts being fully amortized at the end of 2018 and an increase of approximately $40,000 in board of directors compensation expense for the three months ended March 31, 2019 compared to the three months ended March 31, 2018. 

Other Income (Expense)

For the three months ended March 31, 2019, we recognized no interest income compared to $4 during the three months ended March 31, 2018.

Income Tax Provision

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

26

Liquidity and Capital Resources

As of March 31, 2019 and December 31, 2018, we had an aggregate of $250,464 and $1,368,395, respectively, of cash and cash equivalents. Our condensed consolidated financial statements have been prepared assuming we will continue as a going concern, which contemplates, among other things, the realization of assets and satisfaction of liabilities in the normal course of business. 

Historically, our operations have primarily been funded through proceeds from equity and debt financings, as well as revenue from operations. In June and July 2017, we sold 1,725,000 shares of our common stock in a public offering, including an over-allotment option exercised by the underwriters. We received net proceeds of approximately $7,900,000 after deducting underwriting discounts and commissions and related expenses. We incurred a total of $1,565,386 in issuance costs in connection with the Public Offering. In addition, in April 2019, we closed a follow-on offering, pursuant to which we sold 847,750 shares of our common stock. In connection with the follow-on offering, we also sold common stock purchase warrants to purchase up to an aggregate of 847,750 shares of common stock. Such warrants were sold in a private placement pursuant to Section 4(a)(2) and Rule 506(b) under the Securities Act of 1933, as amended. We received net proceeds of approximately $692,248 after deducting certain fees due to the placement agent and certain transaction expenses.

We anticipate that we will continue to generate losses from operations for the foreseeable future. As of March 31, 2019, our stockholders’ equity was $6,806,140, compared to $7,080,067 as of December 31, 2018. Our net loss from operations for the three months ended March 31, 2019 was $490,735 and net cash used in operating activities was $1,117,931. 

We are attempting to generate sufficient revenues, and may need to secure additional financing sources, such as debt or equity capital, to support our daily operations and fund future growth, which financing may not be available on favorable terms or at all. We currently have a Form S-3 shelf registration statement on file with the Securities and Exchange Commission. If we issue additional equity securities to raise funds, our existing stockholders may experience further dilution, and the new equity securities may have rights, preferences and privileges senior to those of our existing stockholders. If we issue debt securities to raise additional funds, we may incur debt service obligations, become subject to additional restrictions that limit or restrict our ability to operate our business or be required to encumber our assets. There can be no assurance that we will be able to raise any such capital on terms acceptable to us, if 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. 

Management believes that the actions presently being taken to further implement its business plan and generate sufficient revenues provide the opportunity for us to continue as a going concern. While we believe in the viability of our strategy to increase revenues and in our ability to raise additional funds, we cannot provide any assurances to that effect. Our ability to continue as a going concern is dependent upon our ability to further implement our business plan and generate sufficient revenues.

The condensed consolidated financial statements do not include any adjustments that might be necessary if we are unable to continue as a going concern. 

Cash Flow Summary

	Three  Month Ended March 31,
	2019				2018
Net cash provided by (used in):
Operating activities		$	(1,117,931	)	$	(384,783	)
Investing activities			—			26,853
Financing activities			—			—
Net increase (decrease) in cash and cash equivalents		$	(1,117,931	)	$	(357,930	)

Operating activities used net cash of $1,117,931 in the three months ended March 31, 2019, and $384,783 in the three months ended March 31, 2018. Generally, our net operating cash flows fluctuate primarily based on changes in our profitability and working capital. Cash used in operating activities increased by $733,148 primarily from a decrease in working capital of $970,000 and a net decrease of $111,035 in amortization, offset by a decrease in net loss of $263,369 and a net increase of $82,504 in stock compensation expense in the three months ended March 31, 2019 compared to three months ended March 31, 2018. 

Investing activities provided no net cash in the three months ended March 31, 2019, and net cash of $26,853 in the three months ended March 31, 2018 primarily due to an increase in proceeds from short-term investments.

Financing activities provided no net cash in the three months ended March 31, 2019, and 2018.

27

We provide services to our 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 March 31, 2019, we had eleven projects totaling $95,839,840 under contract, which, if they all proceed to construction, will result in our constructing approximately 677,536 square feet of container space. Of these contracts, two projects totaling approximately 32,320 square feet were in the architectural and engineering phase and nine projects totaling approximately 645,216 square feet were contracts combining all three phases or parts thereof and including construction. We expect that all of this revenue will be realized by June 30, 2021.

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 at March 31, 2019 from the prior year is primarily attributable to work in progress or completed contracts during the first quarter for approximately $1,735,000.

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 March 31, 2019 and December 31, 2018, we had no material off-balance sheet arrangements to which we are a party.

Critical Accounting Policies 

Our condensed consolidated financial statements have been prepared using generally accepted accounting principles in the United States of America (“GAAP”), which require management to make estimates and assumptions that affect reported amounts. The estimates and assumptions are based on historical experience and on other factors that management believes to be reasonable. Actual results may differ from those estimates. Critical accounting policies represent the areas where more significant judgments and estimates are used in the preparation of our condensed consolidated financial statements. A discussion of such critical accounting policies, which include share-based payments, derivative instruments, goodwill, intangible assets and revenue recognition, can be found in our 2018 Form 10-K. There have been no material changes in critical accounting policies from those disclosed in the 2018 Form 10-K. 

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 stock-based compensation expense.

EBITDA and Adjusted EBITDA are presented because they are important metrics used by management as one of the means by which it assesses 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.

28

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

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

	Three Months Ended March 31, 2019			Three Months Ended March 31, 2018
Net loss	$	(490,735	)	$	(754,104	)
Addback depreciation and amortization		39,446			148,247
EBITDA (non-GAAP)		(451,289	)		(605,857	)
Addback stock-based compensation expense		162,493			79,989
Adjusted EBITDA (non-GAAP)	$	(288,796	)	$	(525,868	)

Not applicable.

ITEM 4.      Controls and Procedures

Disclosure Controls and Procedures

Management, 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 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.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the fiscal quarter covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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 Company provides two main products, both of which are used to meet the growing demand for safe and green commercial, industrial and residential building construction. The Company provides SGBlocks_^TM, code engineered cargo shipping containers that the Company modifies for use in construction. Rather than consuming new steel and lumber, SGBlocks^TM capitalize on the structural engineering and design parameters a shipping container must meet and repurposes them for use in building. They offer the construction industry a safer, greener, faster, longer lasting and more economical alternative to conventional construction methods. The Company also provides purpose-built modules (“SGPBMs” and, together with SGBlocks^TM, “Modules”), which are prefabricated steel modular units created specifically for use in modular construction, unlike the shipping containers used to create SGBlocks_^TM.  

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

2. Liquidity 

The Company has prepared its condensed consolidated financial statements on a going concern basis, which assumes that the Company will realize its assets and satisfy its liabilities in the normal course of business. However, the Company has incurred net losses since its inception and has negative operating cash flows, which raise substantial doubt about its ability to continue as a going concern. The accompanying financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from the outcome of the uncertainty concerning the Company’s ability to continue as a going concern.

As of March 31, 2019, the Company had cash and cash equivalents of $250,464 and a backlog of $95.8 million. See Note 8 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: 

	2019
Within 1 year	$	20,847,051
1 to 2 years		54,546,876
Thereafter		20,445,913
Total Backlog	$	95,839,840

Based on the expected conversion timeline of its backlog, the Company expects to generate positive cash flows from operations for the year ending December 31, 2019. 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 by containing costs and entering into strategic alliances, as well as exploring other options, including the possibility of raising additional debt or equity capital as necessary. The Company completed an equity offering in April 2019, which resulted in net proceeds of approximately $692,248. See Note 13 for a discussion of the offering. 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.

Summary of Significant Accounting Policies

3. Summary of Significant Accounting Policies

Basis of presentation and principals of consolidation – The accompanying unaudited condensed consolidated 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 Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for annual financial statements. The condensed consolidated financial statements and notes should be read in conjunction with the financial statements and notes for the year ended December 31, 2018 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, as filed with the Securities and Exchange Commission on March 29, 2019. 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 three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019.

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, SG Building Blocks, Inc. and SG Residential, Inc. All significant intercompany accounts and transactions have been eliminated. Certain prior period amounts have been reclassified to conform to the current period’s presentation.

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

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The update’s principal objective is to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet. ASU 2016-02 continues to retain a distinction between finance and operating leases but requires lessees to recognize a right-of-use asset representing their right to use the underlying asset for the lease term and a corresponding lease liability on the balance sheet for all leases with terms greater than twelve months. The update is effective for fiscal years beginning after December 15, 2018. In July 2018, the FASB issued ASU No. 2018-11, “Leases (Topic 842): Targeted Improvements” (“ASU 2018-11”), which provides entities with an additional transition method. Under ASU 2018-11, entities have the option of recognizing the cumulative effect of applying the new standard as an adjustment to beginning retained earnings in the year of adoption while continuing to present all prior periods under previous lease accounting guidance. In July 2018, the FASB also issued ASU No. 2018-10, “Codification Improvements to Topic 842, Leases” (“ASU 2018-10”), which clarifies how to apply certain aspects of ASU 2016-02. The Company adopted ASU 2016-02, ASU 2018-10 and ASU 2018-11 effective January 1, 2019. The Company had no operating or finance lease agreements as of March 31, 2019. The adoption of ASU No. 2016-02 did not have a material impact on the Company’s financial statements and disclosures. 

In June 2018, the FASB issued ASU No. 2018-07, “Compensation — Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting” (“ASU 2018-07”), which expands the scope of Topic 718 to include all share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 specifies that Topic 718 applies to all share-based payment transactions in which the grantor acquires goods and services to be used or consumed in its own operations by issuing share-based payment awards. Under ASC 718, the measurement date for equity-classified, share-based awards is generally the grant date of the award. ASU 2018-07 also clarifies that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under ASC 606. The Company adopted ASU 2018-07 effective January 1, 2019. The adoption provides administrative relief by fixing the remaining unamortized expense of the award and eliminating the requirement to quarterly re-measure the Company’s nonemployee awards. The adoption of ASU No. 2018-07 did not have a material impact on the Company’s financial statements and disclosures.

Recently issued accounting pronouncements not yet adopted – New accounting pronouncements requiring implementation in future periods are discussed below. 

In January 2017, the FASB issued ASU No. 2017-04, “Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”), to simplify the test for goodwill impairment by removing Step 2. An entity will, therefore, perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the fair value, not to exceed the total amount of goodwill allocated to the reporting unit. An entity still has the option to perform a qualitative assessment to determine if the quantitative impairment test is necessary. The ASU is effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted. Adoption of the ASU is on a prospective basis. Based on current evaluation, the Company does not expect that ASU No. 2017-04 will have a material impact on the Company’s financial statements.

In August 2018, the FASB issued ASU No. 2018-13, “Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”). This ASU amends ASC 820 to add, remove and modify certain disclosure requirements for fair value measurements. For example, public companies will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU 2018-13 is effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. Management does not expect the adoption of ASU 2018-13 to have a material impact on the Company’s financial position, results of operations or cash flow.

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 and allowance for doubtful accounts. 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 current and long-term 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 applies recognition of revenue over time, which is similar to the method the Company applied under previous guidance (i.e., percentage of completion). 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

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. 

Disaggregation of Revenues

The Company’s revenues are principally derived from construction and engineering contracts related to Modules. Our contracts are with many different customers in numerous industries.

The following tables provide further disaggregation of the Company’s revenues by categories:

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 doubtful accounts. 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 and labeled as “costs and estimated earnings in excess of billings on uncompleted contracts”.

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 and labeled as “billings in excess of costs and estimated earnings on uncompleted contracts”.

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.

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 $250,464 as of March 31, 2019 and $1,368,395 as of December 31, 2018. 

Short-term investment – The Company classifies any investment with a maturity greater than three months but less than one year as short-term investment.  The Company had no short-term investments as of March 31, 2019 or December 31, 2018.

Accounts receivable and allowance for doubtful accounts – 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 account receivable at invoiced amounts. 

The allowance for doubtful accounts reflects the Company's best estimate of probable losses inherent in the accounts receivable balances. Management provides an allowance for doubtful accounts 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 the Company’s estimates and could be material to its consolidated financial position, result of operations, and cash flows. 

Inventory – Raw construction materials (primarily shipping containers) 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. There was no inventory as of March 31, 2019 or December 31, 2018.

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 first assesses qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount, including goodwill. If management concludes that it is more likely than not that the fair value of the reporting unit is less than its carrying amount, management conducts a two-step quantitative goodwill impairment test. The first step of the impairment test involves comparing the fair value of the applicable reporting unit with its carrying value. If the carrying amount of the reporting unit exceeds the reporting unit’s fair value, management performs the second step of the goodwill impairment test. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit’s goodwill with the carrying value of that goodwill. The amount by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss. The Company’s evaluation of goodwill completed during the year ended December 31, 2018 resulted in no impairment losses.

Intangible assets – Intangible assets represent the preliminary assets identified upon emergence from bankruptcy and consist of $2,766,000 of proprietary knowledge and technology which is being amortized over 20 years and $1,113,000 of customer contracts which was being amortized over 2.5 years. In addition, intangible assets include $28,820 of trademarks and $5,300 of website costs which are being amortized over 5 years. The Company evaluated intangible assets for impairment during the year ended December 31, 2018, and determined that there were no impairment losses. The accumulated amortization as of March 31, 2019 and 2018 was $1,505,472 and $1,026,889, respectively. The amortization expense for the three months ended March 31, 2019 and 2018 was $36,281 and $147,316, respectively. The estimated amortization expense for the successive five years is as follows:

For the year ended December 31,
2019	$	108,843
2020		145,124
2021		145,124
2022		140,801
2023		139,007
Thereafter		1,728,749
	$	2,407,648

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 life for significant classes of assets are as follows: computer and software 3 to 5 years and equipment 5 to 7 years. Repairs and maintenance are charged to expense when incurred.

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).

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 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. 

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 its 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 March 31, 2019 and December 31, 2018, 72% and 76%, respectively, of the Company’s accounts receivable were due from two customers.

Revenue relating to two and three customers represented approximately 89% and 80% of the Company’s total revenue for the three months ended March 31, 2019 and 2018, respectively.

Cost of revenue relating to two and three vendors represented approximately 95% and 75% of the Company’s total cost of revenue for the three months ended March 31, 2019 and 2018, respectively. The Company believes it has access to alternative suppliers, with limited disruption to the business, should circumstances change with its existing suppliers.

Net Income (Loss) Per Share

7. 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 March 31, 2019, there were options, including options granted to non-employees and non-directors, restricted stock units and warrants to purchase 1,080,059, 346,936 and 86,250 shares of common stock, respectively, outstanding that could potentially dilute future net income (loss) per share. Because the Company had a net loss for the three months ended March 31, 2019, 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 March 31, 2018, there were options, including options to non-employees and non-directors, and warrants to purchase 1,188,392 and 86,250 shares of common stock, respectively, outstanding that could potentially dilute future net income (loss) per share.

Balance - end of period	$	95,839,840		$	97,657,379

Backlog at March 31, 2019 included two large contracts entered into by the Company during the third quarter of 2017 and one contract during the last quarter of 2018 in the amounts of approximately $55 million, $15 million and $25 million, respectively. The Company expects that all of this revenue will be realized by June 30, 2021. During the fourth quarter of 2018, the Company moved a contract of $27.5 million out of backlog and into its pipeline until the customer completes a highest and best use analysis of the land. 

The Company’s remaining backlog as of March 31, 2019 represents the remaining transaction price of firm contracts for which work has not been performed and excludes unexercised contract options.  As of March 31, 2019, the aggregate amount of the transaction price allocated to backlog was $95,839,840.

The Company expects to satisfy its backlog which represents the remaining unsatisfied performance obligation on contracts as of March 31, 2019 over the following period:

	2019
Within 1 year	$	20,847,051
1 to 2 years		54,546,876
Thereafter		20,445,913
Total Backlog	$	95,839,840

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.

Public Offering – In June 2017, the Company issued 1,500,000 shares of its common stock at $5.00 per share through a public offering (the “Public Offering”). The Company incurred $1,388,615 in issuance costs from the Public Offering and issued 75,000 warrants valued at $55,475 to the underwriters (as discussed in Note 10).

In July 2017, as permitted by the underwriting agreement entered into in connection with the Public Offering, the underwriters exercised their option to purchase an additional 225,000 shares of common stock at $5.00 per share. The Company incurred $176,771 in issuance costs from this issuance. In connection with this exercise, certain affiliates of the underwriters were granted additional warrants to purchase 11,250 shares of common stock in the aggregate valued at $8,321 (as discussed in Note 10). 

In connection with and prior to the Public Offering, the Company issued 1,801,670 shares of its common stock upon conversion of all outstanding preferred stock and 516,667 shares of its common stock upon conversion of the previously outstanding convertible debentures.

Issuance of Common Stock – In accordance with the Advisory Agreement (as defined below), a consultant was issued 50,000 shares of the Company’s common stock for services that were required to be performed by November 30, 2017. The fair market value of these shares amounted to $254,500 as of November 30, 2017, which was expensed as general and administrative expenses.

11. Share-based Compensation 

On October 26, 2016, the Company’s Board of Directors approved the issuance of up to 500,000 shares of the Company’s common stock in the form of restricted stock or options (“2016 Stock Plan”). Effective January 20, 2017, the 2016 Stock Plan was amended and restated as the SG Blocks, Inc. Stock Incentive Plan, as further amended effective June 1, 2018 (the “Incentive Plan”). The Incentive Plan authorizes the issuance of up to 2,500,000 shares of common stock. It authorizes the issuance of equity-based awards in the form of stock options, stock appreciation rights, restricted shares, restricted share units, other share-based awards and cash-based awards  to non-employee directors and to officers, employees and consultants of the Company and its subsidiaries, except that incentive stock options may only be granted to the Company’s employees and its subsidiary’s employees. The Incentive Plan expires on October 26, 2026, and is administered by the Compensation Committee of the Board of Directors of the Company. Each of the Company’s employees, directors, and consultants are eligible to participate in the Incentive Plan. As of March 31, 2019, there were 1,020,202 shares of common stock available for issuance under the Incentive Plan.

Stock-Based Compensation Expense 

Stock-based compensation expense is included in the consolidated statements of operations as follows:  

	Three Months Ended March 31,
	2019		2018
Payroll and related expenses	$	162,493	$	79,989
Total	$	162,493	$	79,989

The following table presents total stock-based compensation expense by security type included in the consolidated statements of operations:

	Three Months Ended March 31,

Stock options	$	32,098	$	79,989
Restricted stock units		130,395		—
Total	$	162,493	$	79,989

Stock-Based Option Awards 

The fair value of the stock-based option awards granted during the three months ended March 31, 2019 and 2018, were estimated at the date of grant using the Black-Scholes option valuation model with the following assumptions: 

	2019			2018
Expected dividend yield		—	%		—	%
Expected stock volatility		68.35	%		25.70	%
Risk-free interest rate		2.44	%		2.56	%
Expected life		3.00			5.00

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 three months ended March 31, 2019. The table includes options granted to employees and directors of the Company, 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
Outstanding – December 31, 2018		1,105,059		$	1.24	$	4.06		8.41	$	—

Exercisable – March 31, 2019		970,190		$	1.23	$	4.01		8.07	$	—

For the three months ended March 31, 2019 and 2018, the Company recognized stock-based compensation expense of $32,098 and $79,989, respectively, related to stock options. This expense is included in payroll and related expenses in the accompanying consolidated statements of operations.

As of March 31, 2019, there was $131,815 of total unrecognized compensation costs related to non-vested stock options, which will be expensed over a weighted average period of one year. The intrinsic value is calculated as the difference between the fair value of the stock price at year end and the exercise price of each of the outstanding stock options. The fair value of the stock price at March 31, 2019 was $1.84 per share.

In March 2018, the Company granted Mr. Galvin, Mr. Shetty and six employees of the Company options to purchase 82,154, 81,342 and an aggregate of 86,504, respectively, shares of the Company’s common stock with an exercise price of $4.61 per share. These options vest in equal quarterly installments over either a two-year and three-year period and will fully vest by the end of March 31, 2021. The options with a two-year period, which includes those granted to Mr. Galvin and Mr. Shetty, will vest in full by December 31, 2019; the options with a three-year vesting period will vest in full by March 31, 2021. The fair value of these options upon issuance amounted to $320,000.

Non-Employee Stock Options 

In September 2017, in connection with an advisory agreement entered into by the Company (the “Advisory Agreement”), a consultant was granted options to purchase 50,000 shares of the Company’s common stock, with an exercise price of $6.25. The options were scheduled to vest when certain performance conditions were met. These performance conditions consisted of the purchase of fifty modular units from the Company by qualified customers. As of March 31, 2019, the required performance conditions were not met, and the options expired. 

Restricted Stock Units 

Effective July 26, 2018, a total of 27,955 of restricted stock units were granted to the Company’s non-employee directors, under the Company’s stock-based compensation plan, at the calculated fair value of $5.36 per share, which represents the average closing price of the Company’s common stock for the ten trading days immediately preceding and including the grant date. Restricted stock units granted to directors in 2018 vest on the earlier of (A) the first anniversary of the date of the grant or (B) the date of the annual meeting of the Company’s stockholders that occurs in the year immediately following the date of the grant; and are payable six months after the termination of the director from the Board or death or disability.

On March 22, 2019, a total of 314,058 of restricted stock units were granted to Mr. Galvin, Mr. Armstrong, Mr. Shetty, six employees and one consultant of the Company, under the Company's stock-based compensation plan, at the fair value of $2.70 per share, which represents the closing price of the Company's common stock on February 26, 2019. Restricted stock units granted to Mr. Galvin, Mr. Armstrong, Mr. Shetty, and an aggregate of six employees and one consultant of 122,785, 15,432, 114,575 and an aggregate of 61,266, respectively, vest in installments over either a one-year, two-year, three-year and four-year period and will fully vest by the end of December 31, 2022. The fair value of these units upon issuance amounted to $847,957.  

On January 15, 2019 and February 26, 2019, a total of 10,514 of restricted stock units were granted to two of the Company’s non-employee directors, under the Incentive Plan, at the calculated fair value of $2.94 and $2.76 per share, which represents the average closing price of the Company’s common stock for the ten trading days immediately preceding and including the grant date. The restricted stock units granted on January 15, 2019 will vest on January 15, 2020, subject to each individual’s continued service as a director of the Company through such date, and are payable six months after the termination of the director from the Company’s Board of Directors or death or disability. The restricted stock units granted on February 26, 2019 vest on the earlier of (A) the first anniversary of the date of the grant or (B) the date of the 2019 annual meeting of the Company’s stockholders subject to each individual’s continued service as a director of the Company through such date, and are payable six months after the termination of the director from the Board of Directors or death or disability.

For the three months ended March 31, 2019 and 2018, the Company recognized stock-based compensation expense of $130,395 and $0 related to restricted stock units. This expense is included in the payroll and related expenses in the accompanying condensed consolidated statement of operations. For the three months ended March 31, 2019 and 2018, the Company recognized $54,315 and $0 related to restricted stock units in lieu of accrued compensation.

Commitments and Contingencies

12.  Commitments and Contingencies  

Legal Proceedings

The Company is subject to certain claims and lawsuits arising in the normal course of business. The Company assesses its 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 its 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 to the Company, advice of counsel, and available insurance coverage, the Company believes that its established accruals are adequate and the liabilities arising from the legal proceedings will not have a material adverse effect on its consolidated financial condition. The Company notes, 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 Company’s results of operations for a particular period, depending upon the size of the loss or the Company’s 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 President, 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.

The claims against the Company arise from an Assignment Agreement, dated as of May 30, 2018, between Pizzarotti, Phipps and the Company (the “Assignment Agreement”), pursuant to which the Company intended to provide a letter of credit in exchange for an assignment of the proceeds from certain subcontracted work to be provided by Phipps to Pizzarotti. The Assignment Agreement was ultimately terminated, and the Company returned all payments to Phipps. Notwithstanding the above, Pizzarotti has sued seeking damages for nonperformance of the sub-contracted work and the return of a $500,000 payment from Phipps.

The Company believes that the Assignment Agreement was properly terminated and believes that the claims brought against the Company and Mr. Shetty have no merit. The Company intends to vigorously defend the litigation.

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.

Vendor Litigation – On January 1, 2019, SG Blocks filed a suit against Teton Buildings, LLC (“Teton”) to recover breach of contract damages of approximately $2,100,000 plus attorneys’ fees related to the HOLA Community Partners construction project in Los Angeles, California (the “HOLA Project”), for which Teton was engaged by the Company to supply modular units in early 2017. The Company’s complaint alleged that Teton failed to comply with specific product requirements with respect to the modular units for the HOLA Project and that Teton’s delay and product quality resulted in damages. The Company’s claims include breach of contract, negligence, and breach of express warranty. The lawsuit was filed as SG Blocks, Inc. v. Teton Buildings, LLC; Case Number 2019-02827 in the United States District Court for the Southern District of Texas. 

SG Blocks believes it will prevail on the merits of the case. As with any litigation at this early stage, the cost of litigating and the outcome remain uncertain. 

HOLA Community Partners Matter – There is an ongoing dispute between the Company and HOLA Community Partners, a California non-profit corporation, in connection with the parties’ Construction and Delivery Agreement, dated June 1, 2017, pursuant to which HOLA Community Partners hired the Company for design, engineering, fabrication, and installation services for the construction of the HOLA Project. The Company claims that HOLA Community Partners owes the Company certain amounts due for work performed on the HOLA Project and extra costs incurred due to delays and impacts caused by HOLA Community Partners. HOLA Community Partners disputes the amounts owed, and claims that the Company failed to meet its contractual obligations. The parties are in ongoing settlement discussions. Neither party has commenced litigation as of the date of these condensed consolidated financial statements. 

In addition, the Company is subject to other routine legal proceedings, claims, and litigation in the ordinary course of its business. Defending lawsuits requires significant management attention and financial resources and the outcome of any litigation, including the matters described above, is inherently uncertain. The Company does not, however, currently expect that the costs to resolve these routine matters will have a material adverse effect on its consolidated financial position, results of operations, or cash flows.

Subsequent Events

13. Subsequent Events

On April 25, 2019, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with certain institutional investors (the “Investors”) for the sale by the Company of 847,750 shares (the “Common Shares”) of the Company’s common stock, at a purchase price of $1.10 per share. Concurrently with the sale of the Common Shares, pursuant to the Purchase Agreement, the Company also sold common stock purchase warrants to such Investors to purchase up to an aggregate of 847,750 shares of common stock (the “Warrants”). The Company sold the Common Shares and Warrants for aggregate gross proceeds of approximately $932,525. Subject to certain beneficial ownership limitations, the Warrants will be initially exercisable on the six-month anniversary of the issuance date at an exercise price of $1.375 per share, subject to adjustments as provided under the terms of the Warrants, and include a floor in the provision on voluntary adjustments to the then-current exercise price. The Warrants are exercisable for five years from the initial exercise date. The closing of the sales of these securities under the Purchase Agreement occurred on April 29, 2019.

The estimated net proceeds from the transactions were approximately $692,248 after deducting certain fees due to the placement agent, discussed below, and the Company’s estimated transaction expenses. The net proceeds will be used for working capital purposes. The Common Shares were offered and sold by the Company pursuant to an effective shelf registration statement on Form S-3, which was filed with the Securities and Exchange Commission (the “SEC”) on December 18, 2018 and subsequently declared effective on February 7, 2019 (File No. 333-228882), and the base prospectus contained therein. The Company filed a prospectus supplement with the SEC in connection with the sale of the Common Shares.

The Warrants and the shares issuable upon exercise of the Warrants were sold without registration under the Securities Act of 1933, as amended (the “Securities Act”), in reliance on the exemptions provided by Section 4(a)(2) of the Securities Act as transactions not involving a public offering and Rule 506 promulgated under the Securities Act as sales to accredited investors, and in reliance on similar exemptions under applicable state laws.

In connection with the transactions described above, the Company entered into a placement agency agreement (the “Placement Agency Agreement”) with Roth Capital Partners, LLC (“Roth”), pursuant to which Roth agreed to serve as exclusive placement agent for the issuance and sale of the Common Shares and Warrants. The Company agreed to pay Roth an aggregate fee equal to 7.0% of the gross proceeds received by the Company from the sale of the securities in the transactions. Pursuant to the Placement Agency Agreement, the Company also agreed to grant to Roth or its designees warrants to purchase up to 10% of the aggregate number of shares of Common Stock sold in the transactions, or 84,775 shares (the “Roth Warrants”), which Roth Warrants shall be issued in two series of warrants (50% of the Roth Warrants in each series) and the second series of warrants shall vest ratably upon the exercise of the first series of warrants. The Roth Warrants have substantially the same terms as the Warrants, except that the Roth Warrants have an expiration date of April 25, 2024. The Roth Warrants and the shares issuable upon exercise of the Roth Warrants were issued in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act as transactions not involving a public offering and in reliance on similar exemptions under applicable state laws. The Company also agreed to reimburse Roth for $50,000 of its expenses incurred by it in connection with the offering.

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2019

Accounting Policies [Abstract]

Basis of consolidation

Basis of presentation and principals of consolidation – The accompanying unaudited condensed consolidated 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 Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for annual financial statements. The condensed consolidated financial statements and notes should be read in conjunction with the financial statements and notes for the year ended December 31, 2018 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, as filed with the Securities and Exchange Commission on March 29, 2019. 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 three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019.

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, SG Building Blocks, Inc. and SG Residential, Inc. All significant intercompany accounts and transactions have been eliminated. Certain prior period amounts have been reclassified to conform to the current period’s presentation.

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.

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The update’s principal objective is to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet. ASU 2016-02 continues to retain a distinction between finance and operating leases but requires lessees to recognize a right-of-use asset representing their right to use the underlying asset for the lease term and a corresponding lease liability on the balance sheet for all leases with terms greater than twelve months. The update is effective for fiscal years beginning after December 15, 2018. In July 2018, the FASB issued ASU No. 2018-11, “Leases (Topic 842): Targeted Improvements” (“ASU 2018-11”), which provides entities with an additional transition method. Under ASU 2018-11, entities have the option of recognizing the cumulative effect of applying the new standard as an adjustment to beginning retained earnings in the year of adoption while continuing to present all prior periods under previous lease accounting guidance. In July 2018, the FASB also issued ASU No. 2018-10, “Codification Improvements to Topic 842, Leases” (“ASU 2018-10”), which clarifies how to apply certain aspects of ASU 2016-02. The Company adopted ASU 2016-02, ASU 2018-10 and ASU 2018-11 effective January 1, 2019. The Company had no operating or finance lease agreements as of March 31, 2019. The adoption of ASU No. 2016-02 did not have a material impact on the Company’s financial statements and disclosures. 

In June 2018, the FASB issued ASU No. 2018-07, “Compensation — Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting” (“ASU 2018-07”), which expands the scope of Topic 718 to include all share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 specifies that Topic 718 applies to all share-based payment transactions in which the grantor acquires goods and services to be used or consumed in its own operations by issuing share-based payment awards. Under ASC 718, the measurement date for equity-classified, share-based awards is generally the grant date of the award. ASU 2018-07 also clarifies that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under ASC 606. The Company adopted ASU 2018-07 effective January 1, 2019. The adoption provides administrative relief by fixing the remaining unamortized expense of the award and eliminating the requirement to quarterly re-measure the Company’s nonemployee awards. The adoption of ASU No. 2018-07 did not have a material impact on the Company’s financial statements and disclosures.

Recently issued accounting pronouncements not yet adopted – New accounting pronouncements requiring implementation in future periods are discussed below. 

In January 2017, the FASB issued ASU No. 2017-04, “Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”), to simplify the test for goodwill impairment by removing Step 2. An entity will, therefore, perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the fair value, not to exceed the total amount of goodwill allocated to the reporting unit. An entity still has the option to perform a qualitative assessment to determine if the quantitative impairment test is necessary. The ASU is effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted. Adoption of the ASU is on a prospective basis. Based on current evaluation, the Company does not expect that ASU No. 2017-04 will have a material impact on the Company’s financial statements.

In August 2018, the FASB issued ASU No. 2018-13, “Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”). This ASU amends ASC 820 to add, remove and modify certain disclosure requirements for fair value measurements. For example, public companies will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU 2018-13 is effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. Management does not expect the adoption of ASU 2018-13 to have a material impact on the Company’s financial position, results of operations or cash flow.

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 and allowance for doubtful accounts. 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 current and long-term 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.

Assets and liabilities relating to current and long-term 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 applies recognition of revenue over time, which is similar to the method the Company applied under previous guidance (i.e., percentage of completion). 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

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. 

Disaggregation of Revenues

The Company’s revenues are principally derived from construction and engineering contracts related to Modules. Our contracts are with many different customers in numerous industries.

The following tables provide further disaggregation of the Company’s revenues by categories: 

	Three Months Ended March 31,
Revenue by Customer Type	2019				2018
Multi-Family	$	70,873	4	%	$	—	—	%
Office		1,125,603	65	%		363,629	24	%
Retail		530,659	31	%		114,944	7	%
School		—	—	%		759,835	49	%
Special Use		6,812	—	%		305,118	20	%
Other		1,177	—	%		—	—	%
Total revenue by customer type	$	1,735,124	100	%	$	1,543,526	100	%

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 doubtful accounts. 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 and labeled as “costs and estimated earnings in excess of billings on uncompleted contracts”.

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 and labeled as “billings in excess of costs and estimated earnings on uncompleted contracts”.

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.

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 $250,464 as of March 31, 2019 and $1,368,395 as of December 31, 2018. 

Short-term investment – The Company classifies any investment with a maturity greater than three months but less than one year as short-term investment.  The Company had no short-term investments as of March 31, 2019 or December 31, 2018.

Accounts receivable and allowance for doubtful accounts – 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 account receivable at invoiced amounts. 

The allowance for doubtful accounts reflects the Company's best estimate of probable losses inherent in the accounts receivable balances. Management provides an allowance for doubtful accounts 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 the Company’s estimates and could be material to its consolidated financial position, result of operations, and cash flows. 

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 $250,464 as of March 31, 2019 and $1,368,395 as of December 31, 2018. 

Short-term investment

Short-term investment – The Company classifies any investment with a maturity greater than three months but less than one year as short-term investment.  The Company had no short-term investments as of March 31, 2019 or December 31, 2018.

Accounts receivable and Allowance for Doubtful Accounts

Accounts receivable and allowance for doubtful accounts – 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 account receivable at invoiced amounts. 

The allowance for doubtful accounts reflects the Company's best estimate of probable losses inherent in the accounts receivable balances. Management provides an allowance for doubtful accounts 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 the Company’s estimates and could be material to its consolidated financial position, result of operations, and cash flows. 

Inventory

Inventory – Raw construction materials (primarily shipping containers) 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. There was no inventory as of March 31, 2019 or December 31, 2018.

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 first assesses qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount, including goodwill. If management concludes that it is more likely than not that the fair value of the reporting unit is less than its carrying amount, management conducts a two-step quantitative goodwill impairment test. The first step of the impairment test involves comparing the fair value of the applicable reporting unit with its carrying value. If the carrying amount of the reporting unit exceeds the reporting unit’s fair value, management performs the second step of the goodwill impairment test. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit’s goodwill with the carrying value of that goodwill. The amount by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss. The Company’s evaluation of goodwill completed during the year ended December 31, 2018 resulted in no impairment losses.

Intangible assets

Intangible assets – Intangible assets represent the preliminary assets identified upon emergence from bankruptcy and consist of $2,766,000 of proprietary knowledge and technology which is being amortized over 20 years and $1,113,000 of customer contracts which was being amortized over 2.5 years. In addition, intangible assets include $28,820 of trademarks and $5,300 of website costs which are being amortized over 5 years. The Company evaluated intangible assets for impairment during the year ended December 31, 2018, and determined that there were no impairment losses. The accumulated amortization as of March 31, 2019 and 2018 was $1,505,472 and $1,026,889, respectively. The amortization expense for the three months ended March 31, 2019 and 2018 was $36,281 and $147,316, respectively. The estimated amortization expense for the successive five years is as follows:

For the year ended December 31,
2019	$	108,843
2020		145,124
2021		145,124
2022		140,801
2023		139,007
Thereafter		1,728,749
	$	2,407,648

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 life for significant classes of assets are as follows: computer and software 3 to 5 years and equipment 5 to 7 years. Repairs and maintenance are charged to expense when incurred.

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).

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 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. 

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 its 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 March 31, 2019 and December 31, 2018, 72% and 76%, respectively, of the Company’s accounts receivable were due from two customers.

Revenue relating to two and three customers represented approximately 89% and 80% of the Company’s total revenue for the three months ended March 31, 2019 and 2018, respectively.

Cost of revenue relating to two and three vendors represented approximately 95% and 75% of the Company’s total cost of revenue for the three months ended March 31, 2019 and 2018, respectively. The Company believes it has access to alternative suppliers, with limited disruption to the business, should circumstances change with its existing suppliers.
