For the Three Months Ended March 31, and 2020 (Unaudited)

1. | Description of Business

SG Blocks, Inc. (collectively with its subsidiaries, the “Company,” “we”, “us” or “our”) was previously known as CDSI Holdings, Inc., a Delaware corporation incorporated on December 29, 1993. On November 4, 2011, CDSI Merger Sub, Inc., the Company’s wholly-owned subsidiary, was merged with and into SG Building Blocks, Inc. (“SG Building,” formerly SG Blocks Inc.) (the “Merger”), with SG Building surviving the Merger and becoming a wholly-owned subsidiary of the Company. The Merger was a reverse merger that was accounted for as a recapitalization of SG Building, as SG Building was the accounting acquirer. Accordingly, the historical financial statements presented are the financial statements of SG Building.

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

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

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

The Company is now focusing on entering into licensing agreements across the Company’s construction opportunity verticals.

During 2020, the Company formed, SG Echo, LLC, a wholly owned subsidiary of the Company. SG Echo, LLC was formed to complete the business acquisition as disclosed in Note 9. The Company acquired substantially all the assets of Echo DCL, a Texas limited liability company, except for Echo's real estate holdings for which we obtained a right of first refusal. Echo was a container/modular manufacturer based in Durant, Oklahoma specializing in the design and construction of permanent modular and temporary modular buildings and was one of the Company's key supply chain partners. Echo catered to the military, education, administration facilities, healthcare, government, commercial and residential customers. This acquisition has allowed the Company to expand its reach for the Modules and offer an opportunity to vertically integrate a large portion of our cost of goods sold, as well as increase margins, productivity and efficiency in the areas of design, estimating, manufacturing and delivery and to become the manufacturer of the Company's core container and modular product offerings. T he Company also entered into a joint venture with Clarity Lab Solutions LLC., to provide clinical lab testing related to COVID-19.

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

In addition, during 2021, the Company formed SGB Development Corp. (“SGB Development”), which is wholly-owned by the Company. SGB Development was formed with the purpose of real property development utilizing our technologies.

Reverse Stock Split

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

As of March 31, 2021, the Company had 8,821,289 shares of common stock issued and outstanding.

2. | Liquidity

As of March 31, 2021, the Company had cash and cash equivalents of $10,540,290 and a backlog of approximately $22.9 million. See Note 12 for a discussion of construction backlog. Based on our conversations with key customers, the Company anticipates its backlog to convert to revenue over the following period:

|  |  | 2021 |
| Within 1 year |  | $ | 10,015,230 |
| 1 to 2 years |  |  | 12,856,250 |
| Total Backlog |  | $ | 22,871,480 |

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

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

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

3. | Summary of Significant Accounting Policies

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

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

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

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

3. | Summary of Significant Accounting Policies (continued)

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

(1) Identify the contract with a customer

(2) Identify the performance obligations in the contract

(3) Determine the transaction price

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

(5) Recognize revenue as performance obligations are satisfied

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

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

On October 3, 2019, the Company entered into an Exclusive License Agreement (“ELA” ) pursuant to which it granted an exclusive license for its technology as outlined in the ELA. The ELA is described below. Under the ELA, the Company will receive royalty payments based upon gross revenues earned by the licensee for commercialized products within the field of design and project management platforms for residential use, including single-family residences and multi-family residences, but excluding military housing. The Company has determined that the ELA grants the licensee a right to access the Company’s intellectual property throughout the license period (or its remaining economic life, if shorter), and thus recognizes revenue over time as the licensee recognizes revenue and the Company has the right to payment of royalties. No revenue has been recognized under the ELA for the three months ended March 31, 2021.

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

Contract Assets and Contract Liabilities

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

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

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

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

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

Deferred Contract Costs - Prior to entering into the ELA, the Company was subject to an agreement to construct and develop a certain property (“Original Agreement”), which now is subject to the ELA. Because of this, the Company is no longer obliged to its Original Agreement. Upon entering the ELA, the Company had an outstanding accounts receivable balance of $306,143, which was forfeited and recognized this amount as deferred contract costs. This amount was offset by $102,217, which was reimbursement from the licensee for project costs on this project. The Company incurred total deferred contract costs of $203,926. The Company considered this amount an incremental cost of obtaining that ELA, because the Company expects to recover those costs through future royalty payments. The Company plans to amortize the asset over sixty months, which is the initial term of the ELA because the asset relates to the services transferred to the customer during the contract term. As of March 31, 2021, accumulated amortization related to deferred contract costs amounted to $61,178. During the three months ended March 31, 2021 and 2020, amortization expense relating to the deferred contract costs amounted to $10,196 and $10,197, respectively, and is included in general and administrative expenses on the accompanying condensed consolidated statement of operations.

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

3. | Summary of Significant Accounting Policies (continued)

In consideration for the License, during the initial term, the Licensee agreed to pay the Company a royalty of (x) five percent (5%) on the first $20,000,000 of gross revenues derived from the Licensee’s commercialization of the License (net of customary discounts, sales taxes, delivery charges, and amounts for returns) (the “Gross Revenues”), (y) four and one-half percent (4.5%) on the next $30,000,000 of Gross Revenues, and (z) five percent (5%) on all Gross Revenues thereafter (collectively, the “Royalty”) , subject to the following minimum royalty payments determined on a cumulative basis during the initial term: $500,000 in year 1, $750,000 in year 2, $1,500,000 in year 3, $2,000,000 in year 4, and $2,500,000 in year 5. If the License Agreement is extended beyond the initial term, then the parties will negotiate in good faith the royalty rate and the minimum royalty payments for the renewal term(s). In addition, to the extent the Licensee sublicenses any aspect of the License to a sub-licensee, the Licensee will pay to the Company fifty percent (50%) of all payments received by the Licensee from such sublicensee. The Company may also provide the Licensee with professional services with respect to the License, and the Licensee will reimburse the Company for employees’ time, materials, and expenses incurred in providing such professional services. The Licensee also separately agreed to reimburse the Company for any third-party expenses incurred by the Company in developing the Company’s remaining and future residential projects. As of March 31, 2021, there have been no royalties.

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

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

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

On August 27, 2020 the Company entered into a joint venture agreement with Clarity Lab Solutions, LLC (“Clarity Labs”) (the “JV”). In consideration and subject to Clarity Lab’s services and commitments and provided the agreement remains valid and in force, and is not terminated, the Company agreed to issue 200,000 restricted shares of SGB common stock over a defined vesting period starting in December 1, 2020. Clarity Labs is a licensed clinical laboratory that uses specialized molecular testing equipment and that focuses on the diagnosis and treatment of critical diseases, including COVID-19. Clarity Labs is also engaged in the business of manufacturing, importing and distributions various medical tests. Under the JV, the Company and Clarity Labs will jointly market, sell, and distributed certain products and services (“Clarity Mobile Venture”). As of March 31, 2021, $102,410 was due to Clarity Labs for expenses paid on behalf of Clarity Mobile Venture, and is included in Due to Affiliates on the accompanying consolidated balance sheets. In addition, during the three months ended March 31, 2021, the Company recognized revenue of $60,110 to Clarity Labs, of which $140,258 is included in accounts receivable as of March 31, 2021. The Company has determined it is the primary beneficiary of Clarity Mobile Venture and has thus consolidated the activities in its condensed consolidated financial statements.

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

3. | Summary of Significant Accounting Policies (continued)

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 $10,540,290 as of March 31, 2021 and $13,010,356 as of December 31, 2020.

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

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

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

Inventory – Raw construction materials (primarily shipping containers and fabrication materials) are valued at the lower of cost (first-in, first-out method) or net realizable value. Finished goods and work-in-process inventories are valued at the lower of cost or net realizable value, using the specific identification method. Medical equipment and COVID-19 test and testing supplies are valued at the lower of cost, (first-in, first-out method) or net realizable value. As of March 31, 2021 there was inventory of $4,429 for construction materials, and $929,650 of medical equipment and COVID-19 test and testing supplies. As of December 31, 2020 there was inventory of $4,429 for construction materials, and $773,715 of medical equipment and COVID-19 test and testing supplies.

Goodwill – The Company performs its impairment test of goodwill at the reporting unit level each fiscal year, or more frequently if events or circumstances change that would more likely than not reduce the fair value of its reporting unit below its carrying values. The Company performs a goodwill impairment test by comparing the fair value of the reporting unit with its carrying value and recognizes an impairment charge for the amount by which the carrying value exceeds the fair value, not to exceed the total amount of goodwill. The amount by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss. The Company’s evaluation of goodwill completed during the year ended December 31, 2019 resulted in impairment loss of $2,938,653, which represents the total goodwill impairment loss to date. The impairment loss was due to a deterioration in the Company's estimated future cash flows. There were no impairments during the year ended December 31, 2020 or the three months ended March 31, 2021. The Company has taken the recent COVID-19 pandemic into consideration when determining impairment.

Intangible assets – Intangible assets consist of $2,766,000 of proprietary knowledge and technology, which is being amortized over 20 years. In addition, $97,164 of trademarks, and $47,800 of website costs are being amortized over 5 years. The Company evaluated intangible assets for impairment during the year ended December 31, 2020, and determined that there were no impairment losses. There was no impairment during the three months ended March 31, 2021. The accumulated amortization as of March 31, 2021 and 2020 was $690,262 and $1,650,595, respectively. The amortization expense for the three months ended March 31, 2021 and 2020 was $40,407 and $36,280, respectively. The estimated amortization expense for the successive five years is as follows:

| For the year ending December 31,: |  |  |
| 2021 |  | $ | 125,470 |
| 2022 |  |  | 162,970 |
| 2023 |  |  | 161,176 |
| 2024 |  |  | 160,469 |
| 2025 |  |  | 157,051 |
| Thereafter |  |  | 1,453,566 |
|  |  | $ | 2,220,702 |

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

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

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

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).

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

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

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

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

3. | Summary of Significant Accounting Policies (continued)

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

With respect to receivables, concentrations of credit risk are limited to a few customers in the construction industry. The Company performs ongoing credit evaluations of its customers’ financial condition and, generally, requires no collateral from its customers other than normal lien rights. At March 31, 2021 and December 31, 2020, 84% and 79%, respectively, of the Company’s gross accounts receivable were due from four and three customers.

Revenue relating to two and four customers represented approximately 80% and 73% of the Company's total revenue for the three months ended March 31, 2021 and 2020, respectively.

Cost of revenue relating to two and three vendors represented approximately 28% and 90% of the Company’s total cost of revenue for the three months ended March 31, 2021 and 2020, respectively. The Company believes it has access to alternative suppliers, with limited disruption to the business, should circumstances change with its existing suppliers.

4. | Accounts Receivable

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

|  |  | 2021 |  |  | 2020 |
| Billed: |  |  |  |  |  |
| Construction services |  | $ | 2,049,179 |  |  | $ | 1,391,555 |

| Medical revenue |  |  | 1,098,271 |  |  |  | 1,157,819 |
| Retainage receivable |  |  | 615,136 |  |  |  | 615,136 |
| Other receivable |  |  | 182,012 |  |  |  | 180,748 |
| Total gross receivables |  |  | 4,012,821 |  |  |  | 3,431,522 |
| Less: allowance for credit losses |  |  | (795,914 | ) |  |  | (795,914 | )
| Total net receivables |  | $ | 3,216,907 |  |  | $ | 2,635,608 |

Receivables are evaluated for collectability and allowances for potential losses are established or maintained on applicable receivables. The allowance of doubtful accounts was $795,914 as of March 31, 2021. There was no provision for doubtful accounts, no recoveries collected for doubtful accounts and no write offs during the three months ended March 31, 2021. There was a provision for doubtful accounts of $10,018, and no write offs for the year ended December 31, 2020.

| Net contract assets (liabilities) |  | $ | 769,249 |  |  | $ | (471,604 | )

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

6. | Property, plant and equipment

10. | Leases (continued)

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

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

| Year Ending December 31, |  |  | Operating |  |  | Financing |  |  | Total |
| 2021 |  | $ | 340,209 |  | $ | 15,120 |  | $ | 355,329 |

| 2025 |  |  | 243,000 |  |  | - |  |  | 243,000 |

| Present value of lease liabilities |  | $ | 1,539,367 |  | $ | 45,377 |  | $ | 1,584,744 |

CAT has subleased its leased vacant area for a period of one year, the licensee has the option to terminate at any time after the first six month. Anticipated future lease revenue, under this leases is $1,440,000 for the remaining period ending December 31, 2021 and $320,000 for the year ending December 31, 2022.

11. | Net Income (Loss) Per Share

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

At March 31, 2021, there were options, including options granted to non-employees and non-directors, restricted stock units and warrants to purchase 36,436, 884,343 and 128,090 shares of common stock, respectively, outstanding that could potentially dilute future net income per share. Because the Company had a net loss as of March 31, 2021, it is prohibited from including potential common shares in the computation of diluted per share amounts. Accordingly, the Company has used the same number of shares outstanding to calculate both the basic and diluted loss per share. At March 31, 2020, there were options, including options to non-employees and non-directors, restricted stock units and warrants to purchase 52,337, 9,187 and 53,190 shares of common stock, respectively, outstanding that could potentially dilute future net income per share.

12. | Construction Backlog

The Company expects that all of this revenue will be realized by March 31, 2023. Under the ELA, the Company cannot guarantee, but expects to receive, approximately $2.4 million in royalties for one such project. The Company expects to receive these royalties for this one such project through September 30, 2022. Backlog does not include expected royalty fees to the Company under the ELA from projects to be delivered by our licensee.

The Company’s remaining backlog as of March 31, 2021 represents the remaining transaction price of firm contracts for which work has not been performed and excludes unexercised contract options.

| 1 to 2 years |  |  | 12,856,250 |
| Total Backlog |  | $ | 22,871,480 |

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.

Legal Proceedings

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

Pizzarotti Litigation - On or about August 10, 2018 Pizzarotti, LLC filed a complaint against the Company and Mahesh Shetty, the Company’s former President and CFO, and others, seeking unspecified damages for an alleged breach of contract by the Company and another entity named Phipps & Co. (“Phipps”). The lawsuit was filed as Pizzarotti, LLC. v. Phipps & Co., et al., Index No. 653996/2018 and commenced in the Supreme Court of the State of New York for the County of New York. On or about April 1, 2019, Phipps filed cross-claims against the Company and Mr. Shetty asserting claims for indemnification, contribution, fraud, negligence, negligent misrepresentation, and breach of contract. SG Blocks has likewise cross claimed against Phipps for indemnification and contribution, claiming that any damages to the Plaintiff were the result of the acts or omissions of Phipps and its principals.

Pizzarotti’s suit arose from a contract dated April 3, 2018 that it executed with Phipps whereby Pizzarotti, a construction manager, engaged Phipps to perform stone procuring and tile work at a construction project located at 161 Maiden Lane, New York 10038. Pizzarotti’s claims against the Company arise from a purported assignment agreement dated August 10, 2018, whereby Pizzarotti claims that the Company agreed to assume certain obligations of Phipps under a certain trade contract between Pizzarotti and Phipps & Co. Phipps’ claims against the Company arise from a purported Assignment Agreement, dated as of May 30, 2018, between Pizzarotti, Phipps and the Company (the “Assignment Agreement”), pursuant to which, it is alleged, that the Company agreed to provide a letter of credit in connection with the sub-contracted work to be provided by Phipps to Pizzarotti.

The Company believes that the Assignment Agreement was void for lack of consideration and moved to dismiss the case on those and other grounds. On June 17, 2020, the New York Supreme Court entered an order dismissing certain claims against the Company brought by cross claimant Phipps & Co. Specifically, the court dismissed Phipps’ claims for indemnification, contribution, fraud, negligence and negligent misrepresentation. The court did not dismiss Phipps’ claim for breach of the Assignment Agreement. The issue of the validity of the Assignment Agreement, and the Company’s defenses to the claims brought by the plaintiff Pizzarotti, and cross claimant Phipps, are being litigated. The Company maintains that the Assignment Agreement, to the extent valid and enforceable, was properly terminated and/or there are no damages, and, consequently, that the claims brought against the Company are without merit. The Company intends to vigorously defend the litigation.

The parties have engaged in written discovery but no depositions have been conducted as of yet. By motion dated February 24, 2021, Pizzarotti moved to stay the entire action pending the outcome of a separate litigation captioned Pizzarotti, LLC v. FPG Maiden Lane, LLC et. al., Index No. 651697/2019, involving some of the same parties (but excluding the Company). Phipps cross moved to consolidate the two actions.

The Company opposed both motions. On April 26, 2021, the Court denied both motions and directed the parties to meet and confer concerning the scheduling of depositions. On May 10, 2021, the parties jointly filed with the Court a proposed order providing the completion of depositions of all parties and non-parties by September 30, 2021.

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.

Overview

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

Prior to October 2019, our business model was solely a project-based construction model pursuant to which we were responsible for the design and construction of finished products that incorporated our technology primarily to customers in the multi-family housing, restaurant, military and education industries throughout the United States. In October 2019, we changed our business model for our residential building construction to a royalty fee model when we entered into a five year exclusive license with CPF pursuant to which CPF licensed on an exclusive basis our proprietary technology, intellectual property, any improvements thereto, and any related permits, with the right to develop and commercialize products in the United States and its territories within the field of design and project management platforms for residential use, including, without limitation, single-family residences and multi-family residences, but specifically excluding military housing. The Ridge Avenue Project, a residential housing project in Atlanta has also been excluded from the CPF license. Now, in the United States with respect to residential construction (other than the excluded residential structures) we are not permitted to and are no longer responsible for constructing the Modules that are based on our technology or the related costs and instead that service (including with respect to agreement that were in existence as of the effective date of the license with CPF) is performed by CPF and its subcontractors and any revenue for such residential construction will no longer generated from sales of products directly to the end customer but instead will be generated from royalties received from CPF based on the gross revenue that CPF receives from sales of products that are based upon our technology. Depending upon the success of this new business model, we may expand the licensing business model to commercial and industrial construction. We also are continuing to seek opportunities and potential projects in other target markets, which may develop into licensing opportunities in the future.

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

In September 2020, we acquired substantially all the assets of Echo, a Texas limited liability company, except for Echo's real estate holdings for which we obtained a right of first refusal. Echo is a container/modular manufacturer based in Durant, Oklahoma specializing in the design and construction of permanent modular and temporary modular buildings and was one of our key supply chain partners. Echo catered to the military, education, administration facilities, healthcare, government, commercial and residential customers. This acquisition has allowed us to expand our reach for our Modules and offers us an opportunity to vertically integrate a large portion of our cost of goods sold, as well as increase margins, productivity and efficiency in the areas of design, estimating, manufacturing and delivery. On February 24, 2021, we announced the execution of our option to acquire Echo's real estate holdings.

Recent Business Developments

In January 2021, the Company and other third parties formed Chicago Airport Testing LLC (“CAT”). CAT is in the business of marketing, selling, distributing leasing and otherwise commercially exploiting certain products and services in the COVID-19 testing and other medical industry.

Additionally, during February 2021, the Company formed SGB Development Corp. (“SGB”), which was formed for the purpose of real property development utilizing our technologies. Subsequent to March 31, 2021, we acquired an approximately .50-acre site in Lago Vista, Texas which we plan to build approximately 270,000 square feet of one and two-bedroom condominium units manufactured at our factory in Durant, Oklahoma. SGB will manage the development of this site.

Revenue

During the quarter ended March 31, 2021, we derived revenue from the following three categories of sources: construction services, engineering services and medical revenue. The medical revenue source was a new source that commenced operations in the fourth quarter of 2020 and continued with strong revenue related to COVID-19 samples collected from our Clarity Mobile joint venture in the first quarter 2021. Total revenue for the three months ended March 31, 2021 was $9,187,627 compared to $198,756 for the three months ended March 31, 2020. This increase of $8,988,871 or approximately 4523% was mainly driven by an increase in revenue of approximately $5,896,000 in medical revenue (lab testing, test kit sales and equipment) from mainly the collection of COVID-19 test samples with additional medical revenue from the opening and subletting of the Chicago Area Testing facility, an increase in revenue of approximately $1,460,000 in special use projects which includes one legacy contract commitment related to the SG Echo acquisition, an increase in revenue of approximately $1,085,000 in government projects, an increase in revenue of approximately of $312,000 in medical related construction projects and a moderate increase in construction revenue related to office and hotel projects for approximately $131,000 and $166,000, respectively, for the three months ended March 31, 2021, as compared to March 31, 2020.

Cost of Revenue and Gross Profit

Cost of revenue was $7,979,446 for the three months ended March 31, 2021, compared to $152,775 for the three months ended March 31, 2020. The increase of $7,826,671 or a increase of approximately 5123%, is primarily related to higher testing volumes which required an increase in procurement of COVID-19 tests and testing supplies and higher procurement and manufacturing costs of modifying containers and wood modular units. Due to capabilities of Echo, we have now increased our sales of wood modular units to our customer base.

Gross profit was $1,208,181 and $45,981 for the three months ended March 31, 2021 and 2020, respectively.

Gross profit margin percentage decreased to approximately 13.2% for the three months ended March 31, 2021 compared to approximately 23.1% for the three months ended March 31, 2020. The decrease in gross profit margin percentage was primarily due to a single legacy contract commitment from the acquisition of SG Echo that incurred a loss of approximately $1.0 million due to escalations in material pricing related to COVID-19 and labor overages.

Payroll and Related Expenses

Payroll and related expenses for the three months ended March 31, 2021 were $827,522 compared to $271,808 for the three months ended March 31, 2020. This increase was primarily caused by an increase in salaries and additional head count to help manage the growth of SG Echo and other recently launched subsidiaries such as Chicago Airport Testing, Clarity Mobile Ventures, and SGB Development Corp. of approximately $305,000, and an increase of approximately $247,000 in stock-based compensation expense, recognized for the three months ended March 31, 2021 compared to the three months ended March 31, 2020. We recognized $286,186 in stock-based compensation expense related to payroll and related expenses for the three months ended March 31, 2021, compared to $38,764 for March 31, 2020.

36

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

Other operating expenses (general and administrative expenses, marketing and business development expenses, pre-project expenses) for the three months ended March 31, 2021 were $1,542,116 compared to $523,652 for the three months ended March 31, 2020. The increase resulted primarily from an increase in rent expense of approximately $46,000 related to COVID-19 cold storage charges and rental expense for the Chicago Airport Testing facility, an increase in information technology expense of approximately $83,000, an increase in insurance expense of approximately $17,500 for additional insurance coverage for Clarity Mobile Venture, an increase in contract labor expense of approximately $184,500 with the majority related to Clarity Mobile Venture call center support and Chicago Airport Testing for the start-up of operations. The Company had an increase of approximately $382,000 in laboratory medical expenses mainly from the start-up of operations in Wayne County, Michigan, an increase of $31,500 for manager’s oversight fees related to Clarity Mobile Venture, an increase in depreciation expense of $50,000 and increase in marketing expense by approximately $56,000, We recognized no stock-based compensation expense related to legal expenses and marketing expenses for the three months ended March 31, 2021 and 2020.

Other Income (Expense)

Interest income for the three months ended March 31, 2021 was $17,470 mainly derived from bank interest and interest associated with an outstanding note receivable. There was $4,863 of interest income for the three months ended March 31, 2020. Interest expense for the three months ended March 31, 2021 and 2020 was $363 and $2,811, respectively.

Income Tax Provision

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

Impact of Inflation

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

Impact of Coronavirus (COVID-19)

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

Liquidity and Capital Resources

As of March 31, 2021 and December 31, 2020, we had an aggregate of $10,540,290 and $13,010,356, respectively, of cash and cash equivalents and short-term investments.

Historically, our operations have primarily been funded through proceeds from equity and debt financings, as well as revenue from operations.

In June 2017, we completed a public offering, resulting in net proceeds of approximately $6,800,000 after deducting underwriting discounts and commissions and other expenses. In July 2017, in connection with a public offering, the underwriters exercised their option to purchase 11,250 additional shares of common stock. As a result of the exercise and closing of the option to purchase additional shares, total net proceeds from the public offering were approximately $7,900,000 after deducting underwriting discounts and commissions and related expenses.

In April 2019, we issued 42,388 shares of our common stock at a price of $22.00 per share through a Securities Purchase Agreement with certain institutional investors and accredited investors.

In August 2019, we issued 45,000 shares of our common stock at a price of $17.00 per share pursuant to the terms of an Underwriting Agreement to the public.

In December 2019, we completed the public offering where we issued 857,500 shares of common stock at a public offering price of $3.00 per share resulting in net proceeds of approximately $2,117,948 after deducting underwriting discounts and commissions and other expenses. In our November 2019 debt financing, we received a cash payment in the aggregate amount of $375,000 pursuant to a Securities Purchase Agreement that we entered into with RedDiamond Partners LLC (the “Lender”), and we issued to the Lender a Debenture (the "Debenture") in the aggregate principal amount of $480,770 (representing an original issue discount of 22%), which Debenture was secured by a security interest in all of our existing and future assets, subject to existing security interests and exceptions. We received net proceeds of approximately $326,250 after deducting certain fees due to the placement agent and certain transaction expenses. The Debenture was repaid in full out of the proceeds of our December 2019 public offering.

On February 4, 2020, we entered into a Securities Purchase Agreement with an accredited investor, pursuant to which we issued to the investor a secured note in the aggregate principal amount of $200,000 (the “Note”). The Note bears interest at a rate of nine percent (9%) per annum, is due on July 31, 2023, and is secured under a Pledge Agreement, dated February 4, 2020, entered into with the investor (the “Pledge Agreement”) by a security interest in the royalty payable to us under that certain Exclusive License Agreement, dated October 3, 2019, with CPF GP 2019-1 LLC. We have the right to prepay the Note, in whole or in part, at any time and from time to time, without premium or penalty. During the third quarter of 2020, the Note to investor of $200,000 and unpaid accrued interest of $86,263 was converted into 73,665 shares of common stock.

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

In May 2020, we sold 6,000,000 shares of our common stock at a public offering price of $2.50 per share and on May 15, 2020, pursuant to the terms of the Underwriting Agreement dated May 6, 2020 by and among us and ThinkEquity, a division of Fordham Financial Management, Inc., as representatives of several underwriters named therein ("ThinkEquity"), ThinkEquity was granted an over-allotment option to purchase up to an additional 900,000 shares of our common stock, in connection with the previously announced public offering. On May 15, 2020, ThinkEquity exercised in full such option with respect to all 900,000 shares of our common stock. After giving effect to the full exercise of the over-allotment option, the total number of shares of common stock sold by us in the public offering was 6,900,000 shares of common stock and total net proceeds to us, after deducting underwriting discounts and commissions and other offering expenses payable by us, were approximately $15,596,141.

38

Liquidity and Capital Resources (continued)

We anticipate that we will continue to generate losses from operations until the fourth quarter of 2021. At March 31, 2021 and December 31, 2020 we had a cash balance and short-term investment of $10,540,290 and $13,010,356, respectively. As of March 31, 2021, our stockholders’ equity was $18,283,097, compared to $18,437,823 as of December 31, 2020. Our net loss for the three months ended March 31, 2021 was $1,144,350 and net cash used in operating activities was $2,183,116. We anticipate our cash balance is sufficient to last at least twelve months from May 20, 2021.

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

Cash Flow Summary

| Three Months Ended March 31,
|  |  | 2021 |  | 2020
Net cash provided by (used in): |  |  |  |  |  |  |
Operating activities |  | $ | (2,183,116 | ) | $ | (1,026,812 | )
Investing activities |  |  | (990,388 | ) |  | (400,000 | )

Net increase (decrease) in cash and cash equivalents |  | $ | (2,470,066 | ) | $ | (1,226,934 | )

Operating activities used net cash of $2,183,116 during the three months ended March 31, 2021, and $1,026,812 during the three months ended March 31, 2020. Generally, our net operating cash flows fluctuate primarily based on changes in our profitability and working capital. Cash used in operating activities increased by approximately $1,156,000 primarily due to an decrease in working capital of approximately $1,097,000, an increase of approximately $247,000 in stock-based compensation, an increase of approximately $90,000 in depreciation expense, an increase in the overall net loss of approximately $397,000, in the three months ended March 31, 2021 compared to three months ended March 31, 2020.

Investing activities used net cash of $990,388 during the three months ended March 31, 2021, and $400,000 net cash the three months ended March 31, 2020. Cash used in investing activities increase from the corresponding period of the prior year primarily due to the purchase of property, plant and equipment of approximately, $862,000, purchase of intangible assets of $42,500, and payments on assumed liabilities related to the Echo DCL, LLC acquisition of approximately $86,000.

Financing activities provided net cash of $703,438 during the three months ended March 31, 2021, and $199,878 net cash during the three months ended March 31, 2020. Cash provided by financing activities increased by $503,560 due to an increase in proceeds from conversion of outstanding warrants to common stock.

We provide services to our construction and engineering customers in three separate phases: the design phase, the architectural and engineering phase and the construction phase. Each phase is independent of the other, but builds through a progression of concept through delivery of a completed structure. These phases may be embodied in a single contract or in separate contracts, which is typical of a design build process model. As of March 31, 2021, we had 16 projects totaling $22,871,480 under contract, which, if they all proceed to construction, will result in our constructing approximately 230,481 square feet of container and modular space. Of these contracts, all sixteen projects combine all three phases or parts thereof and including construction. We expect that all of this revenue will be realized by March 31, 2023.

Backlog may fluctuate significantly due to the timing of orders or awards for large projects and is not necessarily indicative of future backlog levels or the rate at which backlog will be recognized as revenue. The decrease in backlog of approximately $2,246,000 from December 31, 2020 is primarily attributable to one new contract we entered into during the first quarter of 2021 for approximately $1,325,000 and offset by work in progress or completed contracts during the first three months of 2021 for approximately $3,300,000.

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.

39

Off-Balance Sheet Arrangements

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

In the ordinary course of business, we enter into agreements with third parties that include indemnification provisions which, in our judgment, are normal and customary for companies in our industry sector. These agreements are typically with consultants and certain vendors. Pursuant to these agreements, we generally agree to indemnify, hold harmless, and reimburse indemnified parties for losses suffered or incurred by the indemnified parties with respect to actions taken or omitted by us. The maximum potential amount of future payments we could be required to make under these indemnification provisions is unlimited. We have not incurred material costs to defend lawsuits or settle claims related to these indemnification provisions. As a result, the estimated fair value of liabilities relating to these provisions is minimal. Accordingly, we have no liabilities recorded for these provisions as of March 31, 2021.

Critical Accounting Policies and New Accounting Pronouncements

Critical Accounting Policies

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

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

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

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

40

Critical Accounting Policies (continued)

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

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

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

(1) Identify the contract with a customer

(2) Identify the performance obligations in the contract

(3) Determine the transaction price

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

(5) Recognize revenue as performance obligations are satisfied

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

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

On October 3, 2019, we entered into an Exclusive License Agreement (“ELA” ) pursuant to which it granted an exclusive license for its technology as outlined in the ELA. The ELA is described below. Under the ELA, we will receive royalty payments based upon gross revenues earned by the licensee for commercialized products within the field of design and project management platforms for residential use, including single-family residences and multi-family residences, but excluding military housing. We have determined that the ELA grants the licensee a right to access our intellectual property throughout the license period (or its remaining economic life, if shorter), and thus recognizes revenue over time as the licensee recognizes revenue and we have the right to payment of royalties. No revenue has been recognized under the ELA for the three months ended March 31, 2021.

We entered into a joint venture agreement with Clarity Lab Solutions, LLC (“Clarity Labs”) (the “JV”) in the fourth quarter of 2020. Revenue from the activities of the JV is related to clinical testing services and is recognized when services have been rendered, which is at a point in time. In addition, we formed Chicago Airport Testing, LLC which collects rental revenue Included in the consideration we expected to be entitled to receive, we estimate its contractual allowances, payer denials and price concessions. During the three months ending March 31, 2021, we recognized $5,955,963 in revenue related to activities through the JV, which is included in medical revenue on the accompanying consolidated statements of operations.

41

Critical Accounting Policies (continued)

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

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

New Accounting Pronouncements

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

Non-GAAP Financial Information

In addition to our results under GAAP, we also present EBITDA and Adjusted EBITDA for historical periods. EBITDA and Adjusted EBITDA are non-GAAP financial measures and have been presented as supplemental measures of financial performance that are not required by, or presented in accordance with, GAAP. We calculate EBITDA as net income (loss) before interest expense, income tax benefit (expense), depreciation and amortization. We calculate Adjusted EBITDA as EBITDA before certain non-recurring adjustments such as loss on conversion of convertible debentures, change in fair value of financial instruments and stock compensation expense.

EBITDA and Adjusted EBITDA are presented because they are important metrics used by management as one of the means by which it assesses our financial performance. EBITDA and Adjusted EBITDA are also frequently used by analysts, investors and other interested parties to evaluate companies in our industry. These measures, when used in conjunction with related GAAP financial measures, provide investors with an additional financial analytical framework that may be useful in assessing us and our results of operations.

EBITDA and Adjusted EBITDA have certain limitations. EBITDA and Adjusted EBITDA should not be considered as alternatives to net income (loss), or any other measures of financial performance derived in accordance with GAAP. These measures also should not be construed as an inference that our future results will be unaffected by unusual o r non-recurring items for which these non-GAAP measures make adjustments. Additionally, EBITDA and Adjusted EBITDA are not intended to be liquidity measures because of certain limitations, including, but not limited to:

| ● | They do not reflect our cash outlays for capital expenditures;

| ● | They do not reflect changes in, or cash requirements for, working capital; and

| ● | Although depreciation and amortization are non-cash charges, the assets are being depreciated and amortized and may have to be replaced in the future, and these non-GAAP measures do not reflect cash requirements for such replacements.

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

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

Non-GAAP Financial Information (continued)

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

ITEM 3. Quantitative and Qualitative Disclosures About Market Risk

Not applicable.

ITEM 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

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

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

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

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

Remediation Steps to Address the Material Weakness

Since identifying the material weakness related to the timely closing of accounting records and technical accounting guidance to complex and/or new transactions, we have taken steps to strengthen the control function related to the financial closing process. These steps included retaining two additional senior accounting resources to help enhance the timeliness of the accounting close process and to have additional oversight for new and complex accounting transactions. We will continue to enhance controls to ensure the financial closing process is effectively implemented. Although we plan to complete this remediation process as quickly as possible, we cannot at this time estimate when the remediation will be completed.

Changes in Internal Control over Financial Reporting

Other than as described above, for the fiscal quarter ended March 31, 2021, there have been no changes in our internal control over financial reporting identified in connection with the evaluations required by Rule 13a-15(d) or Rule 15d-15(d) under the Exchange Act that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

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

PART II. OTHER INFORMATION

ITEM 1. Legal Proceedings

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

ITEM 1A. Risk Factors

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

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

At March 31, 2021 and December 31, 2020, we had cash and cash equivalents and a short-term investment, collectively, of $10,540,290 and $13,010,356, respectively. However, during the three months ended March 31, 2021 and year ended December 31, 2020, we reported a net loss of $1,144,350 and $4,508,162, respectively, and used $2,183,116 and $2,887,950 of cash for operations, respectively. If we are not successful with our efforts to increase revenue, we could experience a shortfall in cash over the next twelve months. If there is a shortfall, we may be forced to reduce operating expenses, among other steps, all of which would have a material adverse effect on our operations going forward.

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

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

A few customers have in the past, and may in the future, account for a significant portion of our revenues in any one year or over a period of several consecutive years. For example, for the three months ended March 31, 2021 approximately 80% of our revenue was generated from two customers and for the year ended December 31, 2020, approximately 61% of our revenue was generated from three customers. Although we have contractual relationships with many of our significant customers, our customers may unilaterally reduce or discontinue their contracts with us at any time. The loss of business from a significant customer could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We rely on certain vendors to supply us with materials and products that, if we were unable to obtain, could adversely affect our business.

We have relationships with key materials vendors, and we rely on suppliers for our purchases of products from them. Any inability to obtain materials or services in the volumes required and at competitive prices from our major trading partners, the loss of any major trading partner or the discontinuation of vendor financing (if any) may seriously harm our business because we may not be able to meet the demands of our customers on a timely basis in sufficient quantities or at all. Other factors, including reduced access to credit by our vendors resulting from economic conditions, may impair our vendors’ ability to provide products in a timely manner or at competitive prices. We also rely on other vendors for critical services such as transportation, supply chain and professional services. Any negative impacts to our business or liquidity could adversely impact our ability to establish or maintain these relationships. For the three months ended March 31, 2021 28% of our costs of revenue related to two vendors. For the year ended December 31, 2020, there were no vendors which represented 10% or more of our cost of revenue.

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

Backlog represents the total dollar amount of revenues we expect to record in the future as a result of performing work under contracts we have been awarded. Backlog may fluctuate significantly due to the timing of orders or awards for large projects and is not necessarily indicative of future backlog levels or the rate at which backlog will be recognized as revenue. We include in backlog only those contracts for which we have reasonable assurance that the customer can obtain the permits for construction and can fund the construction. As of December 31, 2020, our backlog totaled approximately $25.1 million and as of March 31, 2021, our backlog totaled approximately $22.9 million. The decrease in backlog at March 31, 2021 from December 31, 2020 is primarily attributable to work in progress or completed contracts during the first three months of 2021 for approximately $3.3 million and executing one contract during the first quarter of 2021 in the amount of approximately $1.3 million. Our backlog is described more in detail in “Note 12—Construction Backlog” of the notes to our consolidated financial statements included elsewhere in this Quarterly Report. We cannot provide assurance that our backlog will be realized as revenues in the amounts reported or, if realized, will result in profits. In accordance with industry practice, substantially all of our contracts are subject to cancellation, termination or suspension at our customer’s discretion. In the event of a project cancellation, we generally would not have a contractual right to the total revenue reflected in our backlog. Projects can remain in backlog for extended periods of time because of the nature of the project and the timing of the particular services required by the project. In addition, the risk of contracts in backlog being cancelled or suspended generally increases during periods of widespread economic slowdowns or in response to changes in commodity prices.

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

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

At March 31, 2021, there were options, including options granted to non-employees and non-directors, restricted stock units and warrants to purchase 36,436, 884,343 and 128,090 shares of common stock, respectively, outstanding that could potentially dilute future net income per share. Because we had a net loss as of March 31, 2021, it is prohibited from including potential common shares in the computation of diluted per share amounts. Accordingly, we used the same number of shares outstanding to calculate both the basic and diluted loss per share. At March 31, 2020, there were options, including options to non-employees and non-directors, restricted stock units and warrants to purchase 52,337, 9,187 and 53,190 shares of common stock, respectively, outstanding that could potentially dilute future net income per share.
