The following is a summary of the more significant risks relating to the Company. A more detailed description of our risk factors can be found below in Item 1A. Risk Factors. Risks related to our Financial Position and Capital Requirements · We may be unable to raise needed capital, on reasonable terms or at all, should our revenue remain flat or decrease. · 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. · We have incurred net losses in prior periods and there can be no assurance that we will generate income in the future, or that we will be able to successfully achieve or maintain our growth strategy. · An impairment of goodwill could have a material adverse effect on our financial condition and results of operations. 1 Risks Related to our Company · Our residential construction business model using our GreenSteel technology depends upon the support of an independent third-party licensee. · Our residential construction business is difficult to evaluate because we are currently focused on a new business model and have very limited operating history and limited information. · The impact of the COVID-19 coronavirus outbreak, or similar global health concerns, could negatively impact our ability to source certain products, impact product pricing, impact our customers’ ability or that of our licensee to obtain financing or have a negative impact on our business. · We may be unable to successfully integrate the Echo business with its current management and structure and the acquisition of Echo DCL, LLC may not result in the benefits anticipated. · We are dependent on the services of key personnel, a few customers and vendors, the unexpected loss of any of which may adversely affect our operations. · We currently are, and may in the future be, subject to legal proceedings or investigations. · We have identified weaknesses in our internal controls, and we cannot provide assurances that these weaknesses will be effectively remediated or that additional material weaknesses will not occur in the future. Risks Related to our Business and Industry · We and CPF, third party licensee, are dependent on the availability and skill of subcontractors, their willingness to work with us, and their selection of, and ability to obtain, suitable and quality building materials. · We depend on third parties for transportation services, and limited availability or increases in costs of transportation could adversely affect our business and operations. · We may have difficulty protecting our proprietary manufacturing processes. · Expansion of our operations may strain resources, and our failure to manage growth effectively could adversely impact our operating results and harm our ability to attract and retain key personnel. · Our clients may adjust, cancel or suspend the contracts in our backlog. · Our liability for estimated warranties may be inadequate. · We can be adversely affected by failures of persons who act on our behalf to comply with applicable regulations and guidelines. · The cyclical and seasonal nature of the construction industry causes our revenues and operating results to fluctuate, and we expect this cyclicality and seasonality to continue in the future. · Our business depends on the construction industry and general business, financial market and economic conditions. · Our business relies on private investment and a slower than expected economy may adversely affect our results. · A material disruption at one of our suppliers’ facilities could prevent us from meeting customer demand, reduce our sales and negatively affect our overall financial results. · Environmental, health and safety laws and regulations and any changes to, or liabilities arising under, such laws and regulations could have a material adverse effect on our financial condition, results of operations and liquidity. · Our business may be subject to economic and political risks of operating and obtaining supplies from foreign countries, including adverse impact of changes in international trade and tariff policies. · Cybersecurity risks related to the technology used in our operations and other business processes, as well as security breaches of company, customer, employee and vendor information, could adversely affect our business. 2 Risks Related to the Construction Sector · We and CPF, third party licensee, may be dependent upon third-party financing, and our financial condition and results of operations could be negatively affected if additional third-party financing for our customers does not become available. · The construction industry is highly competitive, and such competition may increase the adverse effects of industry conditions, including the consolidation of the industry. · There can be no assurance that Modules or modular construction techniques that utilize our technology and expertise will achieve market acceptance and grow; thus, the future of our business and the modular construction industry as a whole is uncertain. · Government regulations and legal challenges may delay the start or completion of our projects, increase our expenses or limit our building activities, which could have a negative impact on our operations. · The dangers inherent in our operations, such as disruptions to our facilities and project sites, and the limits on insurance coverage could expose us to potentially significant liability costs and materially interfere with the performance of our operations. Risks Related to the Clarity Mobile Venture Sector · There can be no assurance that the velocity of COVID-19 tests being conducted by Clarity Mobile Venture will continue at current rates or be effective for new variants of the COVID-19 virus. · We may be adversely affected by the actions of our competitors, many of whom have substantially greater financial, technical and other resources than we have. · We rely on third-party vendors to supply Clarity Mobile Venture with COVID-19 tests that, if we were unable to obtain, could adversely affect our business. Risks Related to our Common Stock · Our failure to meet the continued listing requirements of the Nasdaq Capital Market could result in a delisting of our common stock. · Our stock price has been subject to fluctuations in the past, has recently been volatile, and will likely continue to be subject to fluctuations and decline, due to factors beyond our control, and investors in our common stock may lose all or part of their investment in our company. · Sales of a substantial number of shares of our common stock in the public market, or the perception that they might occur, could cause the price of our common stock to decline. · 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. · Certain provisions of Delaware law could discourage, delay or prevent a merger or acquisition at a premium price. · As a “smaller reporting company,” we have availed ourselves of reduced disclosure requirements, which may make our common stock less attractive to investors. 3 ITEM 1. BUSINESS. History and Company Overview We are a provider of modular facilities (“Modules”). Prior to the COVID-19 pandemic, the Modules we supplied were primarily for multi-family housing, military and restaurant use and were manufactured by third party suppliers using our proprietary technology and design and engineering expertise, which modifies code- engineered cargo shipping containers and purpose-built modules for use for safe and sustainable commercial, industrial and residential building. With our acquisition in September 2020 of Echo DCL, LLC (“Echo”), one of our key supply chain providers, we now have more control over the manufacturing process and have increased our product offerings to add containers made out of wood. In March 2020, in response to the COVID-19 pandemic we began increasing our focus on providing our Modules as health care facilities for deployable medical response solutions. Our partnership with Clarity Lab Solutions, LLC (“Clarity Labs”) in Miami, Florida, a CLIA-certified laboratory, has allowed us to provide laboratory testing at our Modules. In addition, to providing our Modules as emergency healthcare facilities for rapidly deployable medical response solutions and our conducting testing services at such facilities, we also distribute and sell”) GeneFinder™ COVID-19 Plus RealAmp Kit™ PCR tests pursuant to a non-exclusive distributorship agreement that we entered into with Osang Healthcare Co Ltd (“Osang”) a Republic of Korea company in April 2020. 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 and entered into a five-year exclusive license with CPF GP 2019-1 LLC (“CPF”) under which CPF licensed on an exclusive basis our proprietary technology and intellectual property to develop and commercialize products in the United States (and its territories) for residential use, including, without limitation, single-family residences and multi-family residences, but excluding military housing. Prior to the COVID-19 pandemic, our core customer base was comprised of architects, landowners, builders and developers who use our Modules in commercial and residential structures. Our cargo modified Modules allow 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, rather than consuming new steel and lumber. Our technology and expertise is also used to purpose-build modules, or prefabricated steel modular units customized for use in modular construction (“SGPBMs” and, together with SGBlocks™, “Modules”), primarily to augment or complement an SGBlocks™ structure. In March 2020, we began increasing our focus on providing our Modules as health care facilities for deployable medical response solutions. In May, we entered into a partnership with Grimshaw and Osang for deployment of our D-Tec suite of prefabricated health facilities for on-site immediate COVID-19 testing. In September 2020, we entered the U.S. test lab market by forming a joint venture with Clarity Labs , a manufacturer and market leader of rapid diagnostic tests, to launch CLIA-certified laboratories. Our joint venture with Clarity has allowed us to not only supply our D-Tec suite of prefabricated health facilities but also allows us to provide testing services at such facilities . We have supplied our building modular coronavirus testing centers and provide testing services for Los Angeles International Airport (LAX), Memorial in Wayne County, Michigan and have been selected as a Trusted Testing Partner (TTP) for Hawaii’s COVID-19 travel testing program. 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. 4 License Agreement with CPF GP 2019-1 LLC On October 3, 2019, we entered into an Exclusive License Agreement (the “License Agreement”) with CPF, which at the time was one of our customers, pursuant to which we granted CPF an exclusive license (the “License”) solely within the United States and its legal territories to commercialize our GreenSteel™ proprietary 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, without limitation, single-family residences and multi-family residences, but excluding military housing. As a result of the License, with respect to residential construction using our GreenSteel technology (other than residential construction for the military) in the U.S., we are neither responsible for constructing the Modules that are based on our technology nor responsible for the related costs. Instead, that service is performed by CPF and its subcontractors and our revenue under the License is generated from the royalties we receive from CPF based on the gross revenue that CPF receives from sales of these products based upon our licensed technology. The License Agreement has an initial term of five (5) years, with automatic renewal provisions for subsequent five (5) year periods. The License Agreement provides for customary termination provisions, including the right by us to terminate if CPF fails to make the minimum royalty payments described below. In addition to the exclusion for military housing, our Ridge Avenue Project (described below) was excluded from the License. Echo also produces pre- fabricated modular containers, for both residential and commercial use, using wood as the base material instead of steel containers, which activities are not subject to the License. See “Other Modular Products” below. In consideration for the License, during the initial term, CPF agreed to pay us a royalty of (i) five percent (5%) on the first $20,000,000 of gross revenues derived from CPF’s commercialization of the License (net of customary discounts, sales taxes, delivery charges, and amounts for returns) (the “Gross Revenues”), (ii) four and one- half percent (4.5%) on the next $30,000,000 of Gross Revenues, and (iii) 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. During the year ended December 31, 2020, we did not receive any royalty payments under the License. If the License Agreement is extended beyond the initial term, then the parties have agreed to negotiate in good faith the royalty rate and the minimum royalty payments for the renewal term(s). In addition, to the extent CPF sublicenses any aspect of the License to a sublicensee, CPF will pay to us fifty percent (50%) of all payments received by CPF from such sublicensee. We may also provide CPF with professional services with respect to the License, and CPF will reimburse us for employees’ time, materials, and expenses incurred in providing such professional services. CPF also separately agreed to reimburse us for any third-party expenses incurred by us in developing our remaining and future residential projects. The License Agreement provides for customary indemnification obligations between the parties and further provides that CPF will indemnify us for any claims arising out of the commercialization of the License by CPF or any of its subsidiaries, contractors, or sublicensees. In addition, the License Agreement provides that we will provide CPF with cost estimates for the fabrication and manufacturing of residential projects in our 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 CPF may withhold payment of any royalty due to us under the License Agreement on a dollar-for-dollar basis to offset the costs above the originally estimated amounts. On October 3, 2019, we entered into a Loan Agreement and Promissory Note (the “Loan Agreement”) with CPF GP, which was amended on October 15, 2019 and further amended on November 7, 2019 pursuant to which we agreed to loan CPF GP $750,000 at an annual interest rate of five percent (5%), with a maturity date of July 31, 2023. Under the Loan Agreement, as amended agreed to advance to CPF GP the first installment of the principal amount, equal to $500,000, no later than January 31, 2020 and the second installment of the principal amount, equal to $250,000, no later than April 15, 2020. As security for this loan, we received a security interest in all of CPF GP’s membership interests in the Licensee. If we failed to fund either principal installment, such failure would have constituted a default under the Loan Agreement and a cross default under the License Agreement. On January 21, 2020, pursuant to the Loan Agreement, CPF GP issued to us a promissory note in the principal amount of $400,000 (the “Company Note”) and issued to Paul Galvin, our Chairman and CEO, a promissory note in the principal amount of $100,000 (the “Galvin Note”). The transaction closed on January 22, 2020, on which date we loaned CPF GP $400,000 and Mr. Galvin personally loaned CPF GP $100,000 on behalf of us. The Company Note and Galvin Note bear interest at five percent (5%) per annum, payable, together with the unpaid principal amount of the promissory notes, on the earlier of the July 31, 2023 maturity date or upon the liquidation, redemption sale or issuance of a dividend upon the LLC interests in CPF MF 2019-1 LLC, a Texas limited liability company of which CPF GP is the general partner; provided, that the terms of the Galvin Note provide that all interest payments due to Mr. Galvin under the Galvin Note shall be paid directly to, and for the benefit of, our Company. 5 Distribution Agreement with Osang In April 2020, we expanded our product offerings and began focusing on medical projects. On April 30, 2020, we entered in a Distributorship Agreement (as amended, the "Distributorship Agreement") with Osang, effective as of April 28, 2020, for its GeneFinderTM COVID-19 Plus RealAmp KitTM , designed to detect SARS- CoV-2 (Severe Acute Respiratory Syndrome-Coronavirus 2), the virus that causes COVID-19, through gene-based reverse transcription reaction and real-time polymerase chain reaction (PCR) testing process. On April 30, 2020, the Distributorship Agreement was amended to provide us with certain additional warranties from Osang. The Distributorship Agreement is Osang's standard form of distributorship agreement and provides us with the non-exclusive right to distribute Osang's GeneFinder COVID-19 Plus RealAmp Kit in the United States for a stated term of one (1) year. Pursuant to the terms of the Distributorship Agreement, we are required to make payment for 100% of any purchase order prior to shipment of the product from Osang, though we do not expect to make any cash outlays with respect to any product that we distribute and expect instead to require any third-party purchasers to make the necessary cash outlays as part of a purchase order entered into with us. The Distributorship Agreement does not guarantee us a specific quantity of kits to sell or a customer list, and may be terminated by either party at any time on thirty (30) days' notice. At the end of 2020, we began sales of the GeneFinder COVID-19 Plus RealAmp Kits. To date, the Distribution Agreement has not yielded the anticipated benefits or generated significant revenue. On October 12, 2020, we and Osang, entered into a Managed Supply Agreement (the “Supply Agreement”) relating to the consignment (the “Consignment”) to us for 180 days of two (2) million units of Osang's flagship Genefinder Plus RealAmp Covid-19 PCR Test (the “Product”) from Osang for the cold-chain storage and distribution of Product in the United States of America and Canada by us on behalf of ourself, as well as for Osang to other distributors in Territory as well as for direct sales by Osang worldwide where permissible for a period of 180 days thereafter. The Supply Agreement provides that we have no payment obligation to Osang for the Consignment until we sell the Product and that any unsold Product will remain the responsibility of Osang, except that we are responsible for the cold-storage fees. Notwithstanding Osang’s agreement to use its best efforts to sell the Products from the Consignment with priority, to date Osang has not drawn one unit of Product from the Consignment. On April 14, 2021, we filed suit against Osang for breach of contract and fraud seeking damages in the amount of $12 to $15 million in U.S. District Court in the Eastern District of New York (CV 21-1990). See Item 3. Legal Proceedings. Joint Development Agreement with Grimshaw On May 27, 2020, we entered into a Joint Development Agreement with Grimshaw Design, LLC ("Grimshaw"). Grimshaw is engaged in architecture, planning and industrial design. Our joint agreement is to develop a prototype and "proof of concept" for a scalable, customizable and rapidly deployable medical facility with laboratory systems, testing booths, spaces for in-patient and out-patient care and/or other medical care units, based upon Grimshaw's designs and utilizing our container- based or other modular structures, or pre-fabricated modular structures jointly developed by us and Grimshaw. On July 6, 2020, we expanded our relationship with Grimshaw when we entered into another Joint Development Agreement with Grimshaw. Our joint agreement is to develop a prototype and "proof of concept" for a scalable, customizable and rapidly deployable educational facility with classrooms, spaces for teaching, workshops, dining, recreation, sports and/or other education-related purposes, based upon Grimshaw's designs and utilizing our container-cased or other modular structures, or pre- fabricated modular structures jointly developed by us and Grimshaw. On November 19, 2020, we and Memorial Hospital, of Michigan (“Memorial), entered into a Professional Services and Capital Support Contract (“PSCSC”) with Wayne County, Michigan to appoint Memorial the primary contractor for the construction of portable on-site laboratory facilities for COVID-19 testing. The PSCCS engages the Company as a sub-contractor to render services and support to Memorial in connection with the fulfillment of statements of work submitted from Wayne County to Memorial. The program deploys the D-Tec Product Series, designed by Grimshaw and developed by SG Blocks, to deliver COVID-19 PCR testing and on-site CLIA lab services directly into high risk and underserved areas. The D-Tec 1 Units are expected to be deployed throughout Wayne County and will provide sample extraction. Clarity Mobile Venture will be the primary operator of the facility. 6 Joint Venture with Clarity Lab Solutions, LLC On August 27, 2020, we entered into a joint venture agreement (the “Clarity Mobile Venture”) with Clarity Labs, a CLIA-certified laboratory based in Miami, Florida. Under the Clarity Mobile Venture, we, along with Clarity Labs have agreed to jointly market, sell, and distribute certain lab testing products and services (“Clarity Mobile Venture”). On November 12, 2020, Clarity Mobile Venture entered into a contract with the City of Los Angeles for the operations of a COVID-19 PCR Test Laboratory at Los Angeles International Airport ("LAX") to provide a full-service modular COVID-19 laboratory and testing facility onsite at Los Angeles International Airport. This facility conducts PCR tests with results available within three hours for passengers and airline crew, and no later than 24 hours for LAX airport employees. Additionally, other rapid coronavirus tests including antigen tests are expected to become available. Clarity Mobile Venture is the primary operator. On November 16, 2020, we announced that the State of Hawaii had selected Clarity Labs and Clarity Mobile Venture to provide COVID-19 testing and clinical laboratory at LAX for testing of passengers travelling between Los Angeles and Hawaii. Acquisition of Echo DCL, LLC On September 17, 2020, we, through our wholly owned subsidiary SG Echo, entered into an Asset Purchase Agreement (“Asset Purchase Agreement”) with Echo DCL, LLC, a container/modular manufacturer that had been a key supplier of ours, to acquire substantially all the assets of Echo, except for Echo's real estate holdings, for which SG Echo has obtained a right of first refusal to acquire same. On September 23, 2020, we, SG Echo and Echo completed the transactions as contemplated by the Asset Purchase Agreement (the “Closing”). Pursuant to the terms of the Asset Purchase Agreement, at the Closing we paid to Echo an aggregate of $1,059,600 in cash, subject to the escrow of certain of the purchase price funds, and SG Echo agreed to pay certain of Echo’s indebtedness, including the obligation to (i) satisfy a Guidance Line of Credit loan (“GLOC Loan”) in the principal amount of approximately $616,000 ($316,432 of which payoff proceeds was delivered by SG Echo to SG DCL at the closing), (ii) pay the debt service on certain of Echo’s indebtedness in the approximate principal amount of $1.7 million for 12 months following the closing, (iii) pay the monthly principal and interest due under the BTH Credit Line in the principal amount of $500,000 for 12 months following the closing and if Seller has not fully satisfied the outstanding principal and interest due under the BTH Credit Line and caused the BTH Lender to release and terminate any Encumbrances on the Purchase Assets arising out of the BTH Credit Line, Buyer may pay the outstanding principal and interest due, and (iv) pay earn out payments equal to the net income received from the acquired business during the 3-month period beginning on the first day of the first full month that is 3 months after the closing date, the 3-month period following the first earn out period and the 3-month period following the second earn out period, payable in 50% in cash and 50% in shares of our common stock to be valued a $2.50 per share; provided, that up to approximately $300,000 of any amounts paid in respect of the GLOC Loan, and any amounts paid in respect of the debt service on Echo’s indebtedness and line of credit with BTH Bank, as described in subparagraphs (i), (ii) or (iii) above, shall be offset against and reduce the earnout payments due to Echo DCL. In no event may the number of shares of common stock to be issued to Echo exceed 19.99% of our outstanding shares on the date of the execution of the Asset Purchase Agreement. Recent Developments Effective December 7, 2020, the Company appointed William B. Rogers to serve as the Company’s Chief Operations Officer. Pursuant to an offer letter signed by Mr. Rogers on November 11, 2020 (the “Offer Letter”), Mr. Rogers will receive an annual salary of $300,000 per year and an annual bonus of up to 50% of his salary at the discretion of management and the Board of Directors (the “Board”) of the Company. Mr. Rogers was issued an initial grant of 100,000 restricted stock units following a 90- day probationary period, pursuant to the SG Blocks, Inc., Stock Incentive Plan, as amended (the “Incentive Plan”) which will vest over a two-year period. On February 17, 2021, we formed SGB Development Corp., a Delaware corporation (“SGB Dev Co”) with the express purpose of real property development utilizing our technologies. We expect SG Dev Co will be a co-developer and owner of real estate development projects that deliver apartments and homes for sale. The homes and apartments will be manufactured by SG Echo so that the project is fully integrated into the SGBX eco-system. Many of the projects will utilize the products designed and manufactured through SG Home to reduce design costs, which savings can be passed on to buyers. SGB Dev Co has announced a 225-apartment unit project known as Lago Vista on Lake Travis in booming Austin, Texas. The land closing is scheduled for Q2 2021, and the estimated manufacturing revenue from this project alone to SG Echo is approximately $30 million dollars over 36 months. Our profit share from sales is anticipated in the range of $5 to $7 million dollars over the period the units are sold. Each project will have a third party real estate investor and day to day Manager so that we do not need to finance projects or be distracted from manufacturing excellence. On February 24, 2021, we announced the execution of our option to acquire Echo’s real estate holdings in Durant, OK, consisting of a 19-acre site and all of its structures. We expect to close on the Echo site in the second quarter of 2021. 7 Products Produced with Our GreenSteel™ Modular Technology 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 SG Blocks 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 SG Blocks 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 involves GreenSteel technology and engineering expertise. The first product offering involves GreenSteel Modules, which are the structural core and shell of an SG Blocks building. We procure the containers, engineer required openings with structural steel enforcements, paint the containers and then deliver them on-site, where the customer or a customer’s general contractor will complete the entire finish out and installation. The second product offering involves replicating the process to create the GreenSteel product and, in addition, installing selected materials, finishes and systems (including, but not limited to floors, windows, doors, interior painting, electrical wiring and fixtures, plumbing outlets and bathrooms, roofing system) and delivering SG Blocks 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 SG Blocks 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. Other Modular Products We also produce pre-fabricated modular containers, for both residential and commercial use, at Echo using wood as the base material instead of steel containers. We have found that many clients prefer a mix of wood and steel containers for their projects, wood for aesthetics and cost-savings, and steel for stability and durability. Since our acquisition of Echo, approximately 65% of our Module sales have been for wood-based modules. ESR Approval In April 2017, the ICC Evaluation Service, LLC (“ICC-ES”) granted us an Evaluation Service Report (“ESR”) for the SGBlocks structural building materials. We believe we are the first modular building company to receive such certification. Our ESR indicates that the ICC-ES recognizes the suitability and technical capabilities of the SGBlocks structural building materials for use in compliance with the International Building Code and Residential Code, the California Building Code and Residential Code, and the Florida Building Code—Building and Residential. We believe our ESR has expedited reviews and approvals by state and local building departments, helped the SGBlocks concept gain wider acceptance in the construction industry and opened up licensing opportunities internationally We also believe the ESR will make it more difficult for other companies in the industry to compete with us because the quality control and design acceptance criteria are specific to us and our associated facilities. Our ESR is site-specific; therefore, only the inspected and approved facilities can place the ICC-ES mark on the containers. We currently source or fabricate our SGBlocks from 18 facilities located throughout the continental United States. The ICC-ES has currently approved six of these facilities to place the ICC-ES medallion and we will seek ICC-ES approval for additional facilities on an as needed basis. Each of these facilities undergo an annual inspection by ICC-ES. Currently, each of these facilities has been re-certified by ICC-ES and is current with their recertifications. All SGBlocks manufactured at these facilities have an ESR medallion that validates the quality control process. Because our ESR does not cover SGPBMs, this certification does not extend to buildings constructed using SGPBMs. 8 Target Markets To date, the target markets for the products that utilize our technology and expertise have been the new construction market in the United States. The Modules that utilize our technology and expertise have a particular application in a number of segments, including: ● Single-Family and Multi-Family Housing ● Restaurants and Quick Service Restaurants ● Military ● Education/Student Housing ● Health Care ● Equipment Enclosures and Stacking Solutions ● Office and Commercial ● Commercial and residential customers ● Athletic facilities and support structures ● Administration Facilities In addition, future target markets for expansion of such products and services include data centers, warehouse/public storage, reclamation/drop off centers and medical. Our Competitive Strengths Although the construction industry is highly competitive, we are committed to educating the real estate community on the benefits of our technology and expertise and positioning the products that utilize our technology and expertise as complementary to the strategy of developers, rather than as competition. We and CPF may compete for building opportunities with regional, national and international builders that possess greater financial, marketing and other resources than we do, and competition within the general construction industry may increase if there is future consolidation in the land development and construction industry or from new building technologies that could arise. Within the modular building space, we compete against a small number of companies providing modular-building services. The principal competitive factors in our business include, but are not limited to, the availability of building materials; technical product knowledge and expertise; previous experience in modular construction; consulting or other service capabilities; pricing of products; and the marketability of our ESR within the structural building space. 9 We believe we can distinguish ourselves from our competitors on the basis of our ESR, quality, cost and construction time savings when utilizing our technology and expertise. Our proprietary construction for our cargo based containers method is typically less expensive than traditional construction methods, particularly in urban locations and multi-story projects, and construction time is also generally reduced by using our construction method, reducing both construction and soft costs substantially. SGBlocks are designed to be hurricane-, tornado- and earthquake-resistant and able to withstand harsh climate conditions. The flexibility and the stack-ability of the Modules allows architects, developers and owners to design Modules to meet their specific needs. In addition, our management team has a breadth of knowledge in the modular building industry with a combined 130 years of experience. Our experience in a wide range of construction applications, including office, enclosures, residential, commercial, quick service restaurants, experiential and restaurant applications, gives us an advantage over our competition through the use of market-based prototypes. With the acquisition of Echo, we have been able to vertically integrate our manufacturing process and reduce some of our cost of goods sold, productivity and efficiency. Our Customers We market our construction products to a broad customer base, comprised primarily of contractors, home builders, building owners and other resellers across the continental United States and we also market our services and technology to customers in Canada. In addition, as stated above, we now also supply our Modules to the medical community. SG Blocks customers come from all walks in the economy and include government agencies, private developers, the U.S. Military, the Native American Community, the QSR operators, individuals and families requiring COVID-19 tests and a host of entrepreneurs looking to launch ideas and technology. At December 31, 2020 and 2019, 79% and 92%, respectively, of the Company’s gross accounts receivable were due from three and one customers. Revenue relating to three and two customers represented approximately 61% and 78% of the Company’s total revenue for the years ended December 31, 2020 and 2019, respectively. Our Suppliers and Partners Although the primary use of shipping containers is for transportation, when constructing SGBlocks we use standard materials to modify the container shell structure and finish out the modules. We utilize the same suppliers and materials used by conventional construction. Materials such as windows, doors, insulation mechanical systems, electrical systems and other such supplies are all off-the-shelf materials and equipment commonly available and used in the industry. One of the main suppliers for the procurement of our containers is ConGlobal Industries, Inc. (“ConGlobal”), an independent third party, with whom we have an exclusive 10-year Collaboration and Supply Agreement (the “ConGlobal Agreement”) through May 14, 2024. ConGlobal is one of the largest depot operators in the United States. This arrangement provides us with a reliable source of supply of certified shipping containers. The ConGlobal Agreement provides that ConGlobal will be our exclusive supplier of SGBlocks for housing, office and retail uses generally constructed as permanent structures within the continental United States within a 50 mile radius of an existing ConGlobal site and ConGlobal will not supply shipping containers modified for building purposes to any entity competing with us during the term of the agreement. The Company believes it has access to alternative suppliers, with limited disruption to the business, should circumstances change with its existing suppliers. 10 Intellectual Property We operate under our United States registered trademarks “SGBlocks” and “GreenSteel” and our trademarked “SG” logo. Government Regulation and Approval The design and construction of buildings is controlled at the project level, with local and state municipalities having jurisdiction in most cases. All buildings, conventionally built or modularly built, are subject to published building codes and criteria that must be achieved during the architectural and engineering phase in order to be approved for construction. There are no specific regulations that impact our technology. While much of the regulation in our industry occurs at the project level, we are subject to various federal, state and local government regulations applicable to the business in the jurisdictions in which we operate, including laws and regulations relating to our relationships with our employees, public health and safety, workplace safety, transportation, zoning and fire codes. We strive to operate in accordance with applicable laws, codes and regulations. We believe we are in compliance in all material respects with existing applicable environmental laws and regulations and, in addition, that our employment, workplace health and workplace safety practices comply with related regulations. General Corporate Information We were incorporated in the State of Delaware on December 29, 1993 under the name CDSI Holdings, Inc. On November 4, 2011, CDSI Merger Sub, Inc., our wholly-owned subsidiary, completed a reverse merger with and into SG Building Blocks, Inc. (“SG Building”), with SG Building surviving the reverse merger as our wholly owned subsidiary. We primarily conduct our current operations through SG Building. Prior to our emergence from bankruptcy in June 2016, our common stock was quoted on the OTC Bulletin Board. In June 2017 and December 2019, we completed public offerings of our common stock, which currently trades on the Nasdaq Capital Market under the symbol “SGBX.” Our principal offices are located at 17 State Street, 19th Floor, New York, NY, 10004.

The address of that website is www.sec.gov. Our Emergence from Bankruptcy On October 15, 2015, SGB and its subsidiaries (collectively, the “Debtors”), filed voluntary petitions for reorganization under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the Southern District of New York (the “Bankruptcy Court”) under the caption In re SG Blocks, Inc. et al., Case No. 15-12790. On February 29, 2016, the Debtors filed a Disclosure Statement (the “Disclosure Statement”), attaching a Plan of Reorganization (the “Plan”), along with a motion seeking approval of the Disclosure Statement by the Bankruptcy Court. On June 30, 2016 (the “Effective Date”), the Plan became effective and the Debtors emerged from bankruptcy. Prior to the Effective Date, SGB was authorized to issue: (i) 300,000,000 shares of common stock, par value $0.01 (the “Former Common Stock”) of which 42,918,927 shares were issued and outstanding as of June 29, 2016; and (ii) 5,000,000 shares of preferred stock, par value $0.01 (the “Former Preferred Stock”), none of which were issued and outstanding prior to the Effective Date. On the Effective Date, and pursuant to the terms of the Plan, SGB entered into a Securities Purchase Agreement, dated June 30, 2016, pursuant to which SGB sold for a subscription price of $2.0 million a 12% Original Issue Discount Senior Secured Convertible Debenture to Hillair Capital Investments L.P. (“HCI”) in the principal amount of $2.5 million, with a maturity date of June 30, 2018 (the “Exit Facility”). On the Effective Date, all previously issued and outstanding shares of the Former Common Stock were deemed discharged, cancelled and extinguished, and, pursuant to the Plan, SGB issued, in the aggregate, 8,195 shares (as adjusted to effect a 1-for-20 reverse stock split) of common stock, par value $0.01 (the “New Common Stock”), to the holders of Former Common Stock. Further, under the Plan, upon the Effective Date, certain members of SGB’s management were entitled to receive options (the “Management Options”) to acquire approximately 10,919 shares (as adjusted to effect a 1-for-20 reverse stock split), of SGB’s New Common Stock, on a fully diluted basis. 11 On the Effective Date, pursuant to the terms of the Plan and SGB’s Amended and Restated Certificate of Incorporation, SGB filed with the Secretary of State of the State of Delaware a Certificate of Designations of Convertible Preferred Stock, designating 1,801,670 shares (as adjusted to effect a 1-for-3 reverse stock split) of preferred stock, par value $1.00, all of which were issued upon our emergence from bankruptcy. Prior to our public offering that we consummated in June 2017, all outstanding shares of our preferred stock, were converted into 90,084 shares of common stock. No preferred stock currently remains outstanding. Reverse Stock Split On February 5, 2020, we effected a 1-for-20 reverse stock split of our common stock. All share and per share amounts set forth in the consolidated financial statements have been retroactively restated to reflect the split effected in February 2020 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 this Annual Report have been adjusted to reflect the reverse stock split effected in February 2020. Recent Financing Developments In April 2020, we completed a public offering of common stock (the "April Public Offering"). In connection with the April Public Offering, we sold 440,000 shares of common stock at a public offering price of $4.25 per share, resulting in aggregate net proceeds of approximately $1,522,339 after deducting underwriting discounts and commissions and other expenses related to the offering. We incurred a total of approximately $347,661 in issuance costs in connection with the offering and no warrants to purchase were issued to the underwriters. In May 2020, we completed a public offering of common stock (the "May Public Offering"). In connection with the May Public Offering, we sold 6,000,000 shares of common stock at a public offering price of $2.50 per share. Pursuant to the terms of the related Underwriting Agreement dated May 6, 2020 by and among the Company 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 the Company's common stock, par value $0.01 per share (the "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 the Company's Common Stock (the "Option Shares"). 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 May 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. We incurred a total of approximately $1,653,859 in issuance costs in connection with the offering and issued warrants to purchase 300,000 shares of common stock to the underwriters. Human Capital Employees We believe that our success depends upon our ability to attract, develop and retain key personnel. As of December 31, 2020, SGB directly employed thirteen full- time employees and engaged outside professional firms and subcontractors to deliver projects to customers, and SG Echo directly employed thirty-seven full-time employees. Health and Safety The health and safety of our employees is our highest priority, and this is consistent with our operating philosophy. Accordingly, with the global spread of the ongoing novel coronavirus pandemic, we have implemented plans designed to address and mitigate the impact of the COVID-19 pandemic on the safety of our employees and our business, which include: · Adding work from home flexibility; · Adjusting attendance policies to encourage those who are sick to stay home; · Increasing cleaning protocols across all locations; · Initiating regular communication regarding impacts of the COVID-19 pandemic, including health and safety protocols and procedures; 12 Available Information We are subject to the informational requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and in accordance therewith, we file reports, proxy and information statements and other information with the United States Securities and Exchange Commission (the “SEC”). Our Annual Report on Form 10- K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and any amendments to these reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act are available through the investor relations section of our website at www.sgblocks.com. Reports are available free of charge as soon as reasonably practicable after we electronically file them with, or furnish them to, the SEC. The information contained on our website is not incorporated by reference into this Annual Report on Form 10-K. 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 the other information in this Annual Report on Form 10-K, including the section titled “Forward-Looking Statements,” and Part II, Item 7.“Management’s Discussion and Analysis of Financial Condition and Results of Operation” and our consolidated financial statements and the accompanying notes included elsewhere in this Annual Report on Form 10-K. The risks described below are not the only ones we face. Any of the following risks could materially and adversely affect our business. 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. Our business, financial condition and results of operations could also be harmed by risks and uncertainties not currently known to us or that we currently do not believe are material. Risks Related to our Financial Position and Capital Requirements. 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 December 31, 2020 and 2019, we had cash and cash equivalents and a short-term investment, collectively, of $13,010,356 and $1,625,671, respectively. However, during the fiscal years ended December 31, 2020 and 2019, we reported a net loss of $4,508,162 and $6,920,540, respectively, and used $2,887,950 and $2,815,621 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. 13 We have incurred net losses in prior periods, and there can be no assurance that we will generate income in the future, or that we will be able to successfully achieve or maintain our growth strategy. Our ability to achieve profitability will depend upon our ability to generate and sustain substantially increased revenues. We may continue to incur operating losses in the future as we execute our growth strategy. Although we expect that our expenses will decline due to our new business model, there can be no assurance that our revenue from royalties will exceed our expenses, especially since we anticipate that most of our expenses will be fixed expenses that will not be dependent upon revenue generated. The likelihood that we will generate net income in the future must be considered in light of the difficulties facing the construction industry as a whole, economic conditions and the competitive environment in which we operate. Our operating results for future periods are subject to numerous uncertainties, and we may not achieve sufficient revenues to sustain or increase profitability. In addition, we may be unable to successfully achieve or maintain our growth strategy, including our ability to expand into new geographic markets. An impairment of goodwill could have a material adverse effect on our financial condition and results of operations. As December 31, 2020, we had $1,309,330 of goodwill. We perform an impairment test of our goodwill annually during the fourth quarter of our fiscal year or when events occur or circumstances change that would more-likely-than-not indicate that goodwill might be impaired. Factors that may be considered a change in circumstances, indicating that the carrying value of our goodwill may not be recoverable, include a decline in stock price and market capitalization, reduced future cash flow estimates and slower growth rates in our industry. Our annual impairment tests resulted in no impairment of goodwill during fiscal 2020. The annual impairment test during fiscal 2019 resulted in $2,938,653 of impairment. Deterioration in estimated future cash flows in our reporting unit could result in further future goodwill impairment. Changes to our business strategy, changes in industry or market conditions, changes in operating performance or other indicators of impairment could cause us to record a significant impairment charge during the period in which the impairment is determined, negatively impacting our results of operations and financial position. Risks Relating to the Company Our residential construction business model using our GreenSteel technology depends upon the support of an independent third-party licensee. We entered into an exclusive license agreement with CPF, pursuant to which we granted CPF an exclusive license solely within the United States and its legal territories to commercialize our GreenSteel 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, without limitation, single-family residences and multi-family residences, but specifically excluding military housing. Under the terms of the License Agreement, CPF is to provide us with royalties based upon its sale of products that utilize the licensed technology. Inasmuch as CPF has an exclusive license in the United States, which is the only territory to date where we have been retained to construct products for use for residences, unless we were to either expand residential construction product sales to territories outside of the United States or enter into licensing arrangements similar to that with CPF for sales of products that utilize our technology outside of the United States for residential use or in the United States for business not cover by the License, such as military residences and commercial and industrial construction, we will be totally dependent upon CPF for our revenue for residential construction. CPF is an independent entity and we cannot control the amount or timing of resources that it devotes to such commercialization efforts. CPF may not assign as great a priority to such commercialization efforts or pursue them as diligently as we would if we were undertaking such commercialization ourselves. If CPF or any other licensee fails to devote sufficient time and resources to such commercialization efforts, or if its performance is substandard our ability to generate revenue may be adversely affected. CPF may also have relationships with other commercial entities, some of whom may compete with us. If CPF assists our competitors at our expense, our competitive position would be harmed. In addition, upon certain extraordinary events, CPF is entitled to terminate the license agreement in which case we would be forced to incur the costs to commercialize products for residential construction unless another licensee were found. 14 Our residential construction business is difficult to evaluate because we are currently focused on a new business model and have very limited operating history and limited information. We recently engaged in a new licensing business model for our residential construction business in the United States. We have entered into one license agreement for use of our technology for construction of residences in the United States and if successful, we intend to expand our model and enter into additional similar agreements. There is a risk that we will be unable to successfully generate revenue from this new business model and that we will be unable to enter into additional licensing agreements or that any additional agreements that we enter into will be on favorable terms. Although we believe that we will experience cost savings from this new business model resulting in greater net income since we will no longer require the same level of capital, personnel and equipment as was required from our prior residential construction business model, there can be no assurance that we will experience the level of cost savings that we anticipate or generate the income that we anticipate. We are subject to many risks associated with this new business model such as our dependence upon licensees to commercialize products that utilize our technology. There is no assurance that the licensees activities will be successful or will result in any revenues or profit. Even if we generate revenue, there can be no assurance that we will be profitable. We are subject to the risks inherent to the operation of a new business enterprise, and cannot assure you that we will be able to successfully address these risks. In addition, it is still too early to evaluate the impact of our recent acquisition of Echo. Although we expect to control have better control of cost of goods and efficiency from this acquisition, it is too early to determine the full benefits, if any to be experienced as a result of the acquisition. In December 2019, a novel strain of coronavirus, COVID-19, was reported to have surfaced in Wuhan, China. Since then, the COVID-19 coronavirus has spread to multiple countries, including the United States. The impact of the COVID-19 coronavirus outbreak, or similar global health concerns, could negatively impact our ability to source certain products, impact product pricing, impact our customers’ ability or that of our licensee to obtain financing or have a negative impact on our business. In March 2020, the World Health Organization declared COVID-19 a global pandemic. This contagious disease outbreak, which has continued to spread, and the related adverse public health developments, have adversely affected work forces, economies and financial markets globally. Our use of third-party suppliers for production and shipping of certain products could be negatively impacted by the regional or global outbreak of illnesses, including the COVID-19 coronavirus outbreak. In addition, any outbreak of COVID at our Echo facility could result in closures of the facility and negatively impact our ability to meet timelines. To date, we have experienced some delays in projects due to COVID-19. Any quarantines, the timing and length of containment and eradication solutions, travel restrictions, absenteeism by infected workers, labor shortages or other disruptions to our suppliers and their contract manufacturers or our customers or our licensee, CPF, would likely adversely impact our sales and operating results and result in further project delays. In addition, the pandemic could result in an economic downturn that could affect the ability of our customers and licensees to obtain financing and therefore impact demand for our products. Order lead times could be extended or delayed and pricing could 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 our revenue and our results of operations, the size and duration of which we are currently unable to predict. In addition, the outbreak of the COVID-19 coronavirus could disrupt our operations due to absenteeism by infected or ill members of management or other employees, or absenteeism by members of management and other employees who elect not to come to work due to the illness affecting others in our office or other workplace, or due to quarantines. COVID-19 illness could also impact members of our Board of Directors resulting in absenteeism from meetings of the directors or committees of directors, and making it more difficult to convene the quorums of the full Board of Directors or its committees needed to conduct meetings for the management of our affairs. The global outbreak of the COVID-19 coronavirus continues to rapidly evolve. The extent to which the COVID-19 coronavirus may impact our business and clinical trials will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the outbreak, travel restrictions and social distancing in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the disease. 15 We may be unable to successfully integrate the Echo business with its current management and structure and the acquisition of Echo may not result in the benefits anticipated. Our failure to successfully complete the integration of Echo could have an adverse effect on our prospects, business activities, cash flow, financial condition, results of operations and stock price. Integration challenges may include the following: ● ● assimilating Echo’s technology and retaining personnel; estimating the capital, personnel and equipment required for Echo based on the historical experience of management with the businesses they are familiar with; ● minimizing potential adverse effects on existing business relationships; and ● successfully developing the new products and services. We believe the acquisition of Echo will provide certain strategic benefits which would enable us to accelerate our business plan through an increased access to capital in the public equity markets. However, our employee number has experienced significant growth from the acquisition as has our expenses. There can be no assurance that these anticipated benefits of the acquisition will materialize or that if they materialize will result in increased stockholder value or revenue stream to the combined company. Our ability to meet our workforce needs is crucial to our results of operations and future sales and profitability. We rely on the existence of an available hourly workforce to manufacture our products. We cannot assure you that we will be able to attract and retain qualified employees to meet current or future manufacturing needs at a reasonable cost, or at all. For instance, the demand for skilled employees has increased recently with the low unemployment rates in Oklahoma where we have manufacturing facilities. Also, although none of our employees are currently covered by collective bargaining agreements, we cannot assure you that our employees will not elect to be represented by labor unions in the future. Additionally, competition for qualified employees could require us to pay higher wages to attract a sufficient number of employees. Significant increases in manufacturing workforce costs could materially adversely affect our business, financial condition or results of operations. We have a fixed cost base that will affect our profitability if our sales decrease. The fixed cost levels of operating Echo can put pressure on profit margins when sales and production decline. Our profitability depends, in part, on our ability to spread fixed costs over a sufficiently large number of products sold and shipped, and if we make a decision to reduce our rate of production, gross or net margins could be negatively affected. Consequently, decreased demand or the need to reduce production can lower our ability to absorb fixed costs and materially impact our financial condition or results of operations. A material disruption at one of our suppliers’ facilities or Echo’s facilities could prevent us from meeting customer demand, reduce our sales and negatively affect our overall financial results. Any of the following events could cease or limit operations unexpectedly: fires, floods, earthquakes, hurricanes, on-site or off-site environmental incidents or other catastrophes; global pandemic; utility and transportation infrastructure disruptions; labor difficulties; other operational problems; or war, acts of terrorism or other unexpected events. Any downtime or damage at our suppliers’ facilities or Echo’s facilities could prevent us from meeting customer demand for our products or require us to make more expensive purchases from a competing supplier. If our suppliers were to incur significant downtime, our ability to satisfy customer requirements could be impaired, resulting in customers seeking products from other distributors, as well as decreased customer satisfaction and lower sales and operating income. 16 A natural disaster, the effects of climate change, or other disruptions at our Echo facility could adversely affect our business, financial condition, and results of operations. We rely on the continuous operation of our Echo facility in Durant, Oklahoma for the production of our Modules. Any natural disaster or other serious disruption to our facility due to fire, flood, earthquake, or any other unforeseen circumstance would adversely affect our business, financial condition, and results of operations. In addition, adverse weather conditions, such as increased frequency and/or severity of storms, or floods could impair our ability to operate by damaging our facilities and equipment or restricting product delivery to customers. The occurrence of any disruption at our manufacturing facility, even for a short period of time, may have an adverse effect on our productivity and profitability, during and after the period of the disruption. These disruptions may also cause personal injury and loss of life, severe damage to or destruction of property and equipment, and environmental damage. Although we maintain property, casualty, and business interruption insurance of the types and in the amounts that we believe are customary for the industry, we are not fully insured against all potential natural disasters or other disruptions to our manufacturing facility. The requirements of being a public company may strain our resources, divert management’s attention and affect our ability to attract and retain qualified board members. We are subject to the reporting and corporate governance requirements of the Exchange Act, the listing requirements of the Nasdaq Capital Market and other applicable securities rules and regulations, including the Sarbanes-Oxley Act and the Dodd-Frank Act. Compliance with these rules and regulations will increase our legal and financial compliance costs, make some activities more difficult, time-consuming or costly and increase demand on our systems and resources. Among other things, the Exchange Act requires that we file annual, quarterly and current reports with respect to our business and results of operations and maintain effective disclosure controls and procedures and internal control over financial reporting. In order to continue to maintain our disclosure controls and procedures and internal control over financial reporting to meet this standard, significant resources and management oversight may be required. As a result, management’s attention may be diverted from other business concerns, which could harm our business, financial condition, results of operations and prospects. We also may need to further expand our legal and finance departments in the future, which will increase our costs and expenses. In addition, changing laws, regulations and standards relating to corporate governance and public disclosure are creating uncertainty for public companies, increasing legal and financial compliance costs and making some activities more time-consuming. These laws, regulations and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We intend to invest resources to comply with evolving laws, regulations and standards, and this investment may result in increased general and administrative expense and a diversion of management’s time and attention from revenue-generating activities to compliance activities. If our efforts to comply with new laws, regulations and standards differ from the activities intended by regulatory or governing bodies, regulatory authorities may initiate legal proceedings against us and our business and prospects may be harmed. As a result of disclosure of information in the filings required of a public company, our business and financial condition are more visible, which may result in threatened or actual litigation, including by competitors and other third parties. If such claims are successful, our business, financial condition, results of operations and prospects could be harmed, and even if the claims do not result in litigation or are resolved in our favor, these claims, and the time and resources necessary to resolve them, could divert the resources of our management and harm our business, financial condition, results of operations and prospects. We are dependent on the services of key personnel, and the unexpected loss of their services may adversely affect our operations. Our success depends highly upon the personal efforts and abilities of our senior management team, specifically the efforts of Paul M. Galvin, our Chief Executive Officer, Gerald Sheeran, our Acting Chief Financial Officer, Stevan Armstrong, our Chief Technology Officer, William Rogers, our Chief of Operations and Rockey Butler, our Vice President of Operations. The Company has entered into employment agreements with Messrs. Galvin and Armstrong. The employment agreements with Messrs. Galvin and Armstrong each provide for two-year terms, with automatic renewal after the end of such term. The loss of the services of one or more of these individuals could have a material adverse effect on our business. Our ability to achieve profitability and generate increased revenue will depend upon our ability to retain, and, if necessary, attract experienced management personnel. 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 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. 17 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 year ended December 31, 2020, there were no vendors which represented 10% or more of our cost of revenue. For the year ended December 31, 2019, 74% of our cost of revenue related to three vendors. We currently are, and may in the future be, subject to legal proceedings or investigations, the resolution of which could negatively affect our profitability and cash flows in a particular period. The nature of our operations exposes us to possible litigation claims, including disputes relating to our operations and commercial and contractual arrangements. Often the litigation matters are not totally within our control. We will contest these matters vigorously and will make insurance claims where appropriate, but because of the uncertain nature of litigation and coverage decisions, we cannot predict the outcome of these matters. The costs associated with litigation matters could have a material adverse effect on our financial condition and profitability. In addition, our profitability or cash flow in a particular period could be affected by an adverse ruling in any litigation currently pending in the courts or by litigation that may be filed against us in the future. We are also subject to government regulation, which could result in administrative proceedings in the future. For additional information, see “Item 3. Legal Proceedings.” We have identified weaknesses in our internal controls, and we cannot provide assurances that these weaknesses will be effectively remediated or that additional material weaknesses will not occur in the future. We do not yet have effective disclosure controls and procedures, or internal controls over all aspects of our financial reporting. We are continuing to develop and refine our internal controls over financial reporting . Our management is responsible for establishing and maintaining adequate internal control over our financial reporting, as defined in Rule 13a-15(f) under the Exchange Act. We will be required to expend time and resources to further improve our internal controls over financial reporting, including by expanding our staff. However, we cannot assure you that our internal control over financial reporting, as modified, will enable us to identify or avoid material weaknesses in the future. We have identified material weaknesses in our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our financial statements will not be prevented or detected on a timely basis. The material weaknesses identified to date include (i)insufficient internal controls related to the timely closing of our accounting records, caused by insufficient accounting resources and a lack of formal review procedures and (ii) insufficient internal controls related to the application of technical accounting guidance to complex and/or new transactions. As such, our internal controls over financial reporting were not designed or operating effectively. We will be required to expend time and resources to further improve our internal controls over financial reporting, including by expanding our staff . However, we cannot assure you that our internal control over financial reporting, as modified, will enable us to identify or avoid material weaknesses in the future. Our current controls and any new controls that we develop may become inadequate because of changes in conditions in our business, including increased complexity resulting from our international expansion. Further, weaknesses in our disclosure controls or our internal control over financial reporting may be discovered in the future. Any failure to develop or maintain effective controls, or any difficulties encountered in their implementation or improvement, could harm our operating results or cause us to fail to meet our reporting obligations and may result in a restatement of our financial statements for prior periods. Any failure to implement and maintain effective internal control over financial reporting could also adversely affect the results of management reports and independent registered public accounting firm audits of our internal control over financial reporting that we will eventually be required to include in our periodic reports that will be filed with the SEC. Ineffective disclosure controls and procedures, and internal control over financial reporting could also cause investors to lose confidence in our reported financial and other information, which would likely have a negative effect on the market price of our common stock. 18 Risks Relating to our Business and Industry We, in particular Echo, and CPF are dependent on the availability and skill of subcontractors, their willingness to work with us, and their selection of, and ability to obtain, suitable and quality building materials. We and CPF will rely on subcontractors to perform the actual construction of our building projects and, in many cases, to select and obtain raw materials. Despite detailed specifications and quality control procedures, in some cases, improper construction processes or defective materials may be used to finish construction of our building projects. We and CPF may need to spend money to remediate such problems when they are discovered. Defective products can result in the need to perform extensive repairs to large numbers of buildings. Though subcontracts are written to protect from substandard performance or materials, pervasive problems could adversely affect CPF’s business and therefore our ability to generate royalty income. Our revenue from our CPF is based upon the gross revenue it receives from product sales which is exclusive of amounts repaid or credited by reason of rejection or returns. The inability to contract with skilled subcontractors or general contractors at reasonable costs and on a timely basis could limit our or CPF’s ability to construct and deliver buildings and could erode our profit margins and adversely affect our results of operations and cash flows. We depend on third parties for transportation services, and limited availability or increases in costs of transportation could adversely affect our business and operations. Our business depends on the transportation of a large number of products, via railroad or truck. We rely primarily on third parties for transportation of the products we manufacture or distribute and for the delivery of our raw materials. We are also subject to seasonal capacity constraints, which may be severely reduced due to COVID- 19 coronavirus, and weather-related delays for both rail and truck transportation. If any of our third-party transportation providers were to fail to deliver raw materials to us or our Modules to our customers in a timely manner, we may be unable to complete projects in a timely manner and may, among other things, incur penalties for late delivery or be unable to use the Modules as intended. In addition, if any of these third parties were to cease operations or cease doing business with us, we may be unable to replace them at reasonable cost. Any failure of a third-party transportation provider to deliver raw materials to us or finished Modules to our customers in a timely manner could harm our reputation, negatively affect our customer relationships, and have a material adverse effect on our operating results, cash flows, and financial condition. Additionally, an increase in transportation rates or fuel surcharges could adversely affect our sales, profitability, and cash flows. We may have difficulty protecting our proprietary manufacturing processes, which could adversely affect our ability to compete. We use a proprietary manufacturing process that allows us to be code-compliant in our SGBlocks™ product. Such manufacturing process is unique to the construction industry and is important to ensure our continued success, and we cannot assure you that our efforts to protect our proprietary rights will be sufficient or effective. If other companies replicate our methodology, we could lose our competitive advantage. Any future patent or trademark applications may not lead to issued patents and registered trademarks in all instances. We also cannot be assured that the scope of any patents issued in the future will be sufficiently broad to offer meaningful protection. Others may develop or patent similar or superior technologies, products or services, and our intellectual property rights may be challenged, invalidated, misappropriated or infringed by others. If we are unable to protect and maintain our intellectual property rights, or if there are any successful intellectual property challenges or infringement proceedings against us, our business and revenue could be materially and adversely affected. Expansion of our operations may strain resources, and our failure to manage growth effectively could adversely impact our operating results and harm our ability to attract and retain key personnel. Increased orders for our Modules have placed, and may continue to place, a strain on our operational, financial, and managerial resources and personnel. In addition, execution of our growth strategy will require further substantial capital and effective planning. Significant rapid growth on top of our current operations could greatly strain our internal resources, leading to a lower quality of customer service, reporting problems, and delays, resulting in a loss of market share and other problems that could adversely affect our financial performance. Our efforts to grow could place an additional strain on our personnel, management systems, liquidity, and other resources. If we do not manage our growth effectively, our operations could be adversely affected, resulting in slower, no or negative growth, critical shortages of cash and a failure to achieve or sustain profitability. 19 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, 2019, our backlog totaled approximately $17.6 million and as of December 31, 2020, our backlog totaled approximately $25.1 million. The increase in backlog at December 31, 2020 from December 31, 2019 is primarily attributable to executing two contracts during the third quarter of 2020 in the amount of approximately $4 million and approximately $2.95 million and three contracts during the fourth quarter of 2020 in the amount of approximately $2.7 million, $0.80 million and $0.70 million. Our backlog is described more in detail in “Note 14—Construction Backlog” of the notes to our consolidated financial statements included elsewhere in this Annual 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. Our liability for estimated warranties may be inadequate, which could materially adversely affect our business, financial condition and results of operations. We are subject to construction defect and warranty claims arising in the ordinary course of business. These claims are common in the construction industry and can be costly. At this time, our third-party providers offer guarantees and warranties in accordance with industry standards that flow through to our clients. A large number of warranty claims could have a material adverse effect on our results of operations. We can be adversely affected by failures of persons who act on our behalf to comply with applicable regulations and guidelines. Although we expect all of our associates (i.e., employees), officers and directors to comply at all times with all applicable laws, rules and regulations, there are instances in which subcontractors or others through whom we do business may engage in practices that do not comply with applicable regulations or guidelines. It is possible that our associates may become aware of these practices but do not take steps to prevent them. If we learn of practices relating to buildings constructed on our behalf that do not comply with applicable regulations or guidelines, we will move actively to stop the non-complying practices as soon as possible, and we will take disciplinary action with regard to our associates who were aware of the practices, including in some instances terminating their employment. However, regardless of the steps we take, we may be subject to fines or other governmental penalties, and our reputation may be negatively affected. The cyclical and seasonal nature of the construction industry causes our revenues and operating results to fluctuate, and we expect this cyclicality and seasonality to continue in the future. The construction industry is highly cyclical and seasonal and is influenced by many international, national and regional economic factors, including the availability of consumer and wholesale financing, which may be severely reduced due to COVID-19 coronavirus, seasonality of demand, consumer confidence, interest rates, income levels and general economic conditions, including inflation and recessions. As a result of the foregoing factors, the revenues and operating results we derive from customers and CPF will fluctuate and we currently expect them to continue to fluctuate in the future. Moreover, we have experienced, and may continue to experience, operating losses during cyclical downturns in the construction market. These and other economic factors could have a material adverse effect on demand for our products and our financial condition and operating results. 20 Our business depends on the construction industry and general business, financial market and economic conditions. The construction industry is cyclical and significantly affected by changes in general and local economic and real estate conditions, such as employment levels, consumer confidence, demographic trends, housing demand, inflation, deflation, interest rates and credit availability. Changes in these general and local economic conditions or deterioration in the broader economy could negatively impact the level of purchases, capital expenditures and creditworthiness of our indirect customers and suppliers to CPF s, and, therefore, our royalty income and financial condition, results of operations and cash flows. Changes in these economic conditions may affect some of our regions or markets more than others. If adverse conditions affect our larger markets, they could have a proportionately greater impact on us than on some other companies. In addition, any uncertainty regarding global economic conditions may have an adverse effect on the results of operations and financial condition of us or our customers, distributors and suppliers, such as negative effects of currency exchange fluctuations. A shortage of labor in the construction industry could also have an impact on our financial results. Our business relies on private investment and a slower than expected economy may adversely affect our results. A significant portion of our sales and those of CPF are for projects with non-public owners, such as non-residential builders and home builders who make investments with private funds into their projects. Construction spending is affected by their customers’ ability to finance projects, which may be severely reduced due to the COVID-19 coronavirus. Residential and nonresidential construction could decline if companies and consumers are unable to finance construction projects or if the economy slows or is stalled, which could result in delays or cancellations of capital projects. If the economy slows, or if housing starts and nonresidential projects do not increase, sales of our products directly by us to consumers or by CPF and related services may decline, and our financial position, results of operations and liquidity could be materially adversely affected. A material disruption at one of our suppliers’ facilities or Echo's facilities could prevent us from meeting customer demand, reduce our sales and negatively affect our overall financial results. Any of the following events could cease or limit operations unexpectedly: fires, floods, earthquakes, hurricanes, on-site or off-site environmental incidents or other catastrophes; global pandemic; utility and transportation infrastructure disruptions; labor difficulties; other operational problems; or war, acts of terrorism or other unexpected events. Any downtime or damage at our suppliers’ facilities or Echo's facilities could prevent us from meeting customer demand for our products or require us to make more expensive purchases from a competing supplier. If our suppliers were to incur significant downtime, our ability to satisfy customer requirements could be impaired, resulting in customers seeking products from other distributors, as well as decreased customer satisfaction and lower sales and operating income. Environmental, health and safety laws and regulations and any changes to, or liabilities arising under, such laws and regulations could have a material adverse effect on our financial condition, results of operations and liquidity. We are subject to a variety of federal, state and local laws and regulations relating to, among other things: the release or discharge of materials into the environment; the management, use, generation, treatment, processing, handling, storage, transport or disposal of solid and hazardous wastes and materials; and the protection of public and employee health and safety and the environment. These laws and regulations may expose us to liability for the conduct of others or for our actions, even if such actions complied with all applicable laws at the time these actions were taken. These laws and regulations may also expose us to liability for claims of personal injury or property or natural resource damage related to alleged exposure to, or releases of, regulated or hazardous materials. The existence of contamination at properties we own, lease or operate could also result in increased operational costs or restrictions on our ability to use those properties as intended, including for purposes of construction materials distribution. In addition, because our properties are generally situated adjacent to or near industrial companies, our properties may be at an increased risk of having environmental contaminants from other properties spill or migrate onto or otherwise affect our properties. Despite our compliance efforts, there is an inherent risk of liability in the operation of our business, especially from an environmental standpoint, and, from time to time, we may be in noncompliance with environmental, health and safety laws and regulations. These potential liabilities or non-compliances could have an adverse effect on our operations and profitability. In some instances, we must have government approvals, certificates, permits or licenses in order to conduct our business, which may require us to make significant capital, operating and maintenance expenditures to comply with environmental, health and safety laws and regulations. Our failure to obtain and maintain required approvals, certificates, permits or licenses or to comply with applicable governmental requirements could result in sanctions, including substantial fines or possible revocation of our authority to conduct some or all of our operations. The cost of complying with such laws could have a material adverse effect on our financial condition, results of operations and liquidity. 21 Our business may be subject to economic and political risks of operating and obtaining supplies from foreign countries, including adverse impact of changes in international trade and tariff policies. We operate in and source some of our products from outside of the United States, and our suppliers may also rely upon non-domestic products. As such, any significant changes to, among other things, the general political and social conditions in foreign counties in which we maintain operations or sourcing relationships, unfavorable changes in U.S. trade legislation and regulation, the recent outbreak of the COVID-19 coronavirus, the imposition of governmental economic sanctions on countries in which we do business or other trade barriers, threats of war, terrorism or governmental instability, labor disruptions, currency controls, fluctuating exchange rates with respect to contracts not denominated in U.S. dollars and unanticipated or unfavorable changes in government policies with respect to laws and regulations, anti- inflation measures and method of taxation. If we are unable to navigate foreign regulatory environments, or if we are unable to enforce our contract rights in foreign countries, our business could be adversely impacted. Any of these events could interrupt our business and cause operational disruptions, increase our costs of operations, reduce our sales or otherwise have an adverse effect on our operating performance. The U.S. government has indicated its intent to alter its approach to trade policy, including, in some instances, to revise, renegotiate or terminate certain multilateral trade agreements. It has also imposed new tariffs on certain foreign goods and raised the possibility of imposing additional increases or new tariffs on other goods. Such actions have, in some cases, led to retaliatory trade measures by certain foreign governments. Such policies could make it more difficult or costly for us to do business in or procure products from those countries. In turn, we may need to raise prices or make changes to our operations, which could negatively impact our revenue or operating results. At this time, it remains unclear what additional actions, if any, will be taken by the U.S. government or foreign governments with respect to tariff and international trade agreements and policies, and we cannot predict future trade policy or the terms of any revised trade agreements or any impact on our business. Our operating results will be subject to fluctuations and are inherently unpredictable. In order to achieve profitability, we will need to generate and sustain higher revenue while maintaining reasonable cost and expense levels. In our most recent quarter, we experienced a loss. We do not know if our revenue will grow, or if it will grow sufficiently to outpace our expenses, which we expect to increase as we expand our operational capacity. We may not be able to become profitable on a quarterly or an annual basis. Our quarterly revenue and operating results will be difficult to predict and have in the past fluctuated from quarter to quarter. The amount, timing and mix of project sales, often for a single medium or large-scale project, may cause large fluctuations in our revenue and other financial results. Further, our revenue mix of high margin materials sales versus lower margin projects can fluctuate dramatically quarter to quarter, which may adversely affect our revenue and financial results in any given period. Finally, our ability to meet project completion schedules for an individual project and the corresponding revenue impact under the percentage-of-completion method of recognizing revenue, may similarly cause large fluctuations in our revenue and other financial results. This may cause us to miss any future guidance announced by us. We base our planned operating expenses in part on our expectations of future revenue, and a significant portion of our expenses are fixed in the short-term. If revenue for a particular quarter is lower than we expect, we likely will be unable to proportionately reduce our operating expenses for that quarter, which would harm our operating results for that quarter. This may cause us to miss any guidance announced by us. Cybersecurity risks related to the technology used in our operations and other business processes, as well as security breaches of company, customer, employee and vendor information, could adversely affect our business. We rely on various information technology systems to capture, process, store and report data and interact with customers, vendors and employees. Despite careful security and controls design, as the prevalence of cyber-attacks continues to increase, our information technology systems, and those of our third-party providers, could become subject to increased security threats, such as phishing and malware incidents. Our security measures may be unable to prevent certain security breaches, and any such network, system, data or other breaches could result in misappropriation of sensitive data, transactional errors, theft of funds, business disruptions, loss of or damage to intellectual property, loss of customers and business opportunities, unauthorized access to or disclosure of confidential or personal information (which could cause a breach of applicable data protection legislation), regulatory fines, penalties or intervention, reputational damage, reimbursement or other compensatory costs and additional compliance costs, any of which could have a material adverse effect on our reputation, business, financial condition, results of operations and cash flows. 22 Because the techniques used to obtain unauthorized access to, or disable, degrade or sabotage, information technologies systems change frequently, and may not be recognized until after they have been launched against a target, we may be unable to anticipate these techniques, implement adequate preventative measures or remediate any breach in a timely or effective manner. In addition, the development and maintenance of preventative or detective measures is costly, and requires ongoing monitoring and updating as technologies change and efforts to circumvent security measures become more sophisticated. As well as incurring additional costs, sophisticated hardware and operating system software and applications that we procure from third parties may contain defects in design or manufacture, including “bugs” and other problems that could unexpectedly interfere with the operation of the systems, or we may be unable to successfully integrate and launch new systems as planned without disruptions to our operations. Misuse of internal applications, theft of intellectual property, trade secrets, funds or other corporate assets and inappropriate disclosure of confidential information could stem from such incidents. Despite our efforts, we remain potentially vulnerable to cyber-attacks and security breaches, and any such attack or breach could adversely affect our reputation, business, financial condition or results of operations. We could suffer adverse tax and other financial consequences if we are unable to utilize our net operating loss carryforwards. At December 31, 2020, we had tax net operating loss carry forwards totaling approximately $16.6 million. The net operating loss expires beginning 2030 through 2037 for those losses generated in 2017 and prior years. Approximately $5.5 million of such net operating losses will carry forward indefinitely and be available to offset up to 80% of future taxable income each year. During 2020, the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was passed, which temporarily removes such 80% limitation for years 2020 and 2019. At December 31, 2020, we had a valuation allowance of $4.6 million, primarily related to net operating loss carry forwards that are not more likely than not to be utilized due to an inability to carry back these losses in most states and short carry forward periods that exist in certain states. If we are unable to use our net operating losses, we may be required to record charges or reduce our deferred tax assets, which could have an adverse effect on our results of operations. 23 Risks Relating to the Construction Sector We and CPF are dependent upon third-party financing, and our financial condition and results of operations could be negatively affected if additional third-party financing for our customers does not become available Our business and earnings depend substantially on our ability and the ability of CPF to obtain financing for the development of their construction projects, which may be adversely impacted by the recent COVID-19 coronavirus outbreak. The availability and cost of such financing is further dependent on the number of financial institutions participating in the industry, the departure of financial institutions from the industry, the financial institutions’ lending practices, the strength of the domestic and international credit markets generally, governmental policies and other conditions, all of which are beyond our control. In light of the current economic climate, some of our projects and those of CPF may not be successful in obtaining additional funds in a timely manner, on favorable terms or at all. The availability of borrowed funds, especially for construction financing, has been greatly reduced, and lenders may require project developers to invest increased amounts of equity in a project in connection with both new loans and the extension of existing loans. Unfavorable changes in the availability and terms of financing in the industry will have a material adverse effect on certain privately financed projects. Our results of operations also depend on the ability of any potential privately financed licensees to obtain loans for the purchase of new buildings. Over the past few years, lenders have tightened the credit underwriting standards, which have reduced lending volumes. If this trend continues, it would negatively impact CPF’s sales and our royalty income, which depend in large part on the availability and cost of financing. In addition, where our potential customers must sell their existing buildings or real estate in order to develop new buildings, increases in mortgage costs and/or lack of availability of mortgages could prevent buyers of potential customers’ existing buildings from obtaining the mortgages they need to complete their purchases, which would result in our potential customers’ inability to make purchases from us. If our potential customers cannot obtain suitable financing, our sales and results of operations would be adversely affected. The construction industry is highly competitive, and such competition may increase the adverse effects of industry conditions, including the consolidation of the industry. We operate in a very competitive environment characterized by competition from numerous local, regional and national builders. We may compete for financing, raw materials and skilled management and labor resources. A decline in construction starts could adversely affect demand for our buildings and our results of operations. Increased competition could require us to further increase our selling incentives and/or reduce our prices, which could negatively affect our profits. We may be unable to successfully expand into or compete in the markets in new geographic areas. In addition, while we believe our ESR may improve our competitive position by potentially expediting reviews and approvals by state and local building departments and certifying our specific quality control and design acceptance criteria, there is no assurance that it will have the desired impact. There can be no assurance that Modules or modular construction techniques that utilize our technology and expertise will achieve market acceptance and grow; thus, the future of our business and the modular construction industry as a whole is uncertain. There can be no assurance that we will achieve market acceptance for our technology and expertise or that the modular construction market will grow. Our business may be disrupted by the introduction of new products and services and is subject to changing consumer preferences and industry trends, which may adversely affect our ability to plan for the future development and marketing of our products. Although Modules have particular applications in a wide variety of market segments, there is no assurance that we will be able to expand our relationship within such market segments or, even if we do, that general market acceptance for our technology and expertise or Modules will continue to increase. 24 Government regulations and legal challenges may delay the start or completion of our projects, increase our expenses or limit our building activities, which could have a negative impact on our operations. Various domestic and international rules and regulations concerning building, zoning, sales and similar matters apply to and/or affect the construction industry. Governmental regulation affects construction activities, as well as sales activities, mortgage lending activities and other dealings with consumers. These industries also have experienced an increase in state and local legislation in the United States and regulations that limit the availability or use of land. Municipalities may also restrict or place moratoriums on the availability of utilities, such as water and sewer taps. In some areas, municipalities may enact growth control initiatives, which restrict the number of building permits available in a given year. In addition, we may be required to apply for additional approvals or modify our existing approvals because of changes in local circumstances or applicable law. If governments in locations in which we operate take actions like the ones described, they could adversely affect our business by causing delays, increasing our costs or limiting our ability to operate in those areas. Further, we may experience delays and increased expenses as a result of legal challenges to our proposed projects, whether brought by governmental authorities or private parties. Failure to comply with laws or regulations applicable to or affecting us, or the passage in the future of new and more stringent laws affecting us, may adversely affect our financial condition or results of operations. The dangers inherent in our operations, such as disruptions to our facilities and project sites, and the limits on insurance coverage could expose us to potentially significant liability costs and materially interfere with the performance of our operations. While we believe our insurance coverage is adequate and in line with our industry’s standards, all construction, including modular construction, involves operating hazards that can cause personal injury or loss of life, severe damage to and destruction of property and equipment and suspension of operations, including, but not limited to, natural or man-made disruptions to our facilities and project sites. The failure of such structures during and after installation can result in similar injuries and damages. Although we believe that our insurance coverage is adequate, there can be no assurance that we will be able to maintain adequate insurance in the future at rates we consider reasonable, or that our insurance coverage will be adequate to cover future claims that may arise. Claims for which we are not fully insured may adversely affect our working capital and profitability. In addition, changes in the insurance industry have generally led to higher insurance costs and decreased availability of coverage. The availability of insurance that covers risks we and our competitors typically insure against may decrease, and the insurance that we are able to obtain may have higher deductibles, higher premiums and more restrictive policy terms. Risks Relating to the Clarity Mobile Venture Sector There can be no assurance that the velocity of COVID-19 tests being conducted by Clarity Mobile Venture will continue at current rates or be effective for new variants of the COVID-19 virus. There can be no assurance that the demand for Clarity Mobile Venture’s COVID-19 testing and related laboratory services will continue to grow at the current pace. While we expect that the coronavirus will be a part of our lives for the foreseeable future, viruses constantly change through mutation, and new variants of the COVID-19 virus are expected to occur over time. Our business may be disrupted by the emergence and spread of new variants of the COVID-19 virus that may require different types of tests that may or may not be readily available to us at the time. Currently, we are deploying several COVID-19 tests including the GeneFinder™ test for COVID-19 produced by Osang Healthcare Co., Ltd. and which is effective for the B.1.1.7 (UK) variant, B.1.351 (South Africa) variant and P.1 (Brazil) variant. No assurance can be given that the COVID-19 tests currently deployed by us it will be effective for any future variants. 25 We may be adversely affected by actions of our competitors. The market for COVID-19 testing facilities is highly competitive. Many of our competitors have substantially greater financial, technical and other resources than we have. Our ability to compete effectively depends in part on market acceptance of our testing solutions and our ability to service customers in a timely manner. There can be no assurance that we will be able to compete effectively or that we will respond appropriately to industry trends or to activities of competitors. We rely on third-party vendors to supply us with the COVID-19 tests that Clarity Mobile Venture uses that, if we were unable to obtain, could adversely affect our business. Clarity Mobile Venture relies on third-party vendors to supply it with COVID-19 tests. Any inability to obtain COVID-19 tests in the volumes required and at competitive prices from our vendors, the loss of any major vendor 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. Risks Relating to our Common Stock Our failure to meet the continued listing requirements of the Nasdaq Capital Market could result in a delisting of our common stock. Our common stock is listed on the Nasdaq Capital Market (“Nasdaq” or the “Nasdaq Capital Market”), which imposes, among other requirements, a minimum bid requirement. On July 1, 2019, we received a letter from Nasdaq that, because the closing bid price for our common stock was below $1.00 for 30 consecutive business days, we no longer met the minimum bid price requirement for continued listing on Nasdaq. On February 21, 2020, we received written notice from the Listing Qualifications department of the Nasdaq notifying us that we had regained compliance with the minimum bid price and stockholder’s equity rules. Although we have been able to regain compliance with the continued listing requirements of the Nasdaq Capital Market and are currently in compliance, there can be no assurance that we will be able to maintain compliance in the future. The delisting of our common stock from Nasdaq may make it more difficult for us to raise capital on favorable terms in the future, or at all. Such a delisting would likely have a negative effect on the price of our common stock and would impair your ability to sell or purchase our common stock when you wish to do so. Further, if our common stock were to be delisted from Nasdaq, our common stock would cease to be recognized as a covered security, and we would be subject to additional regulation in each state in which we offer our securities. Moreover, there is no assurance that any actions that we take to restore our compliance with the Nasdaq minimum bid requirement would stabilize the market price or improve the liquidity of our common stock, prevent our common stock from falling below the Nasdaq minimum bid price required for continued listing again or prevent future non-compliance with Nasdaq’s listing requirements. There can be no assurance that we will continue to meet the minimum bid price requirement, or any other requirement in the future. If we fail to meet the minimum bid price requirement, or other applicable Nasdaq listing requirements, including maintaining minimum levels of stockholders’ equity or market values of our common stock, our common stock could be delisted. Delisting from Nasdaq would cause us to pursue eligibility for trading of our common stock on other markets or exchanges, or on an over-the-counter market. In such case, our stockholders’ ability to trade or obtain quotations of the market value of our common stock would be severely limited because of lower trading volumes and transaction delays. These factors could contribute to lower prices and larger spreads in the bid and ask prices of these securities. There can be no assurance that our common stock, if delisted from the Nasdaq, would be listed on a national securities exchange, a national quotation service or the over-the- counter markets. Delisting from the Nasdaq could also result in negative publicity, make it more difficult for us to raise additional capital, adversely affect the market liquidity of our common stock, decrease securities analysts’ coverage of us or diminish investor, supplier and employee confidence. In addition, our stock could become a “penny stock,” which would make trading of our common stock more difficult. 26 Our stock price has been subject to fluctuations in the past, has recently been volatile, and will likely continue to be subject to fluctuations and decline, due to factors beyond our control, and investors in our common stock may lose all or part of their investment in our company. The trading price of our common stock has been and is expected to continue to be volatile and has been and may continue to be subject to wide fluctuations in response to various factors, some of which are beyond our control, including limited trading volume. On March 24, 2021, the reported low sale price of our common stock was $4.38, the reported high sale price was $5.19 and closing price of our common stock was $4.48 while on January 19, 2021, the closing price of our common stock was $8.42. We may incur rapid and substantial decreases in our stock price in the foreseeable future that are unrelated to our operating performance for prospects. In addition to the factors discussed in this “Risk Factors” section and elsewhere in this Annual Report, these factors include: ● ● ● ● ● economic and market conditions or trends in our industry or the economy as a whole and, in particular, in the construction industry; additions or departures of key personnel; operating results that fall below expectations; industry developments; new laws or regulations or new interpretations of existing laws or regulations applicable to our business; ● material litigation or government disputes; ● ● ● ● the public’s response to press releases or other public announcements by us or third parties, including our filings with the SEC; changes in financial estimates or recommendations by any securities analysts who follow our common stock; the size of our market float and potential dilution due to the exercise of outstanding options and warrants; future sales of our common stock by our officers, directors and significant stockholders, including sales pursuant to a registration statement filed to permit a significant stockholder to sell shares of our common stock, pursuant to certain registration rights granted to such stockholder; ● other events or factors, including those resulting from such events, or the prospect of such events, including war, terrorism and other international conflicts, public health issues including health epidemics or pandemics, such as the recent outbreak of the COVID-19 novel coronavirus, and natural disasters such as fire, hurricanes, earthquakes, tornados or other adverse weather and climate conditions, whether occurring in the United States or elsewhere, could disrupt our operations, disrupt the operations of our suppliers or result in political or economic instability; and ● period-to-period fluctuations in our financial results. In addition, the securities markets have, from time to time, experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. These market fluctuations may also materially and adversely affect the market price of our common stock. Since the stock price of our common stock has fluctuated in the past, has recently been volatile and will likely be volatile in the future, investors in our common stock may lose all or part of their investment in our company. In the past, stockholders have instituted securities class action litigation following periods of market volatility. If we were to become involved in securities litigation, we could incur substantial costs and our resources and the attention of management could be diverted from our business. 27 The requirements of being a public company may strain our resources, divert management’s attention and affect our ability to attract and retain qualified board members. We are subject to the reporting and corporate governance requirements of the Exchange Act, the listing requirements of the Nasdaq Capital Market and other applicable securities rules and regulations, including the Sarbanes-Oxley Act and the Dodd-Frank Act. Compliance with these rules and regulations will increase our legal and financial compliance costs, make some activities more difficult, time-consuming or costly and increase demand on our systems and resources. Among other things, the Exchange Act requires that we file annual, quarterly and current reports with respect to our business and results of operations and maintain effective disclosure controls and procedures and internal control over financial reporting. In order to continue to maintain our disclosure controls and procedures and internal control over financial reporting to meet this standard, significant resources and management oversight may be required. As a result, management’s attention may be diverted from other business concerns, which could harm our business, financial condition, results of operations and prospects. We also may need to further expand our legal and finance departments in the future, which will increase our costs and expenses. In addition, changing laws, regulations and standards relating to corporate governance and public disclosure are creating uncertainty for public companies, increasing legal and financial compliance costs and making some activities more time-consuming. These laws, regulations and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We intend to invest resources to comply with evolving laws, regulations and standards, and this investment may result in increased general and administrative expense and a diversion of management’s time and attention from revenue-generating activities to compliance activities. If our efforts to comply with new laws, regulations and standards differ from the activities intended by regulatory or governing bodies, regulatory authorities may initiate legal proceedings against us and our business and prospects may be harmed. As a result of disclosure of information in the filings required of a public company, our business and financial condition are more visible, which may result in threatened or actual litigation, including by competitors and other third parties. If such claims are successful, our business, financial condition, results of operations and prospects could be harmed, and even if the claims do not result in litigation or are resolved in our favor, these claims, and the time and resources necessary to resolve them, could divert the resources of our management and harm our business, financial condition, results of operations and prospects. Sales of a substantial number of shares of our common stock in the public market, or the perception that they might occur, could cause the price of our common stock to decline. The price of our common stock could decline if there are substantial sales of our common stock, particularly sales by our directors, executive officers and significant stockholders. If our existing stockholders sell substantial amounts of our common stock in the public market, or if the public perceives that such sales could occur, this could have an adverse impact on the market price of our common stock, even if there is no relationship between such sales and the performance of our business. In addition, shares subject to outstanding options under our Incentive Plan are and will become eligible for sale in the public market in the future, subject to certain legal and contractual limitations. Substantial sales of such shares, at that time, could depress the sale price of our common stock. Significant sales of our common stock, or the possibility that these sales may occur, might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. In addition, we may issue shares of our common stock in connection with investments or acquisitions in the future. The amount of shares of our common stock issued in connection with an investment or acquisition could constitute a material portion of our then-outstanding shares of common stock. 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. As of April 9, 2021, there are outstanding options and warrants to purchase 36,436 and 128,090 shares of common stock, respectively, in addition to 884,344 vested and unvested restricted stock units. The exercise of such options and warrants and the vesting of restricted stock units would dilute the then-existing stockholders’ percentage ownership of our stock, and any sales in the public market of common stock underlying such securities could adversely affect prevailing market prices for the common stock. Moreover, the terms upon which we would be able to obtain additional equity capital could be adversely affected because the holders of our options and warrants can be expected to exercise them at a time when we would, in all likelihood, be able to obtain any needed capital on terms more favorable to us than those provided by such securities. 28 The issuance of additional securities by our Board of Directors (the “Board” or “Board of Directors”) will dilute the ownership interests of our current stockholders and could discourage the acquisition of us. Our Board, without any action by our stockholders, is authorized to designate and issue additional classes or series of capital stock (including classes or series of preferred stock) as it deems appropriate and to establish the rights, preferences and privileges of such classes or series, and we currently have an effective universal shelf registration statement on file with the SEC, providing for the potential issuance of shares of our common stock and other securities. The issuance of any new class or series of capital stock would not only dilute the ownership interest of our current stockholders but may also adversely affect the voting power and other rights of holders of common stock. The rights of holders of preferred stock and other classes of common stock that may be issued may be superior to the rights of the holders of the existing class of common stock in terms of the payment of ordinary and liquidating dividends and voting rights. In addition, the ability of the Board to designate and issue such shares could impede or deter an unsolicited tender offer or takeover proposal regarding us and the issuance of additional shares having preferential rights could adversely affect the voting power and other rights of holders of common stock and render more difficult the removal of current management, even if such removal may be in the stockholders’ best interests. We do not expect to pay dividends in the future. Any return on investment may be limited to the value of our common stock. For the foreseeable future, we intend to retain any earnings to finance the development and expansion of our business, and we do not anticipate paying any cash dividends on our common stock. Any determination to pay dividends in the future will be at the discretion of our Board of Directors and will depend upon results of operations, financial condition, restrictions imposed by applicable law and other factors our Board of Directors deem relevant. Accordingly, if you purchase shares of our common stock, realization of a gain on your investment will depend on the appreciation of the price of our common stock, which may never occur. Investors seeking cash dividends in the foreseeable future should not purchase our common stock. If securities or industry analysts do not publish research or reports about our business or our industry, or publish negative reports about our business or our industry, our stock price and trading volume could decline. The trading market for our common stock will be influenced by the research and reports that securities or industry analysts publish about us, our business, our industry or our competitors. If one or more of the analysts who cover us change their recommendation regarding our stock adversely, change their opinion of the prospects for our company in a negative manner or provide more favorable relative recommendations about our competitors, our stock price would likely decline. If one or more of these analysts cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our stock price or trading volume to decline. Certain provisions of Delaware law could discourage, delay or prevent a merger or acquisition at a premium price. Certain provisions of Delaware law could discourage potential acquisition proposals, delay or prevent a change in control of our company, or limit the price that investors may be willing to pay in the future for shares of our common stock. Because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three years after the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed manner. Such provisions may discourage, delay or prevent a merger or acquisition of the Company, including a transaction in which the acquirer may offer a premium price for our stock. If our shares become subject to the penny stock rules, it would become more difficult to trade our shares. The SEC has adopted rules that regulate broker-dealer practices in connection with transactions in penny stocks. Penny stocks are generally equity securities with a price of less than $5.00, other than securities registered on certain national securities exchanges or authorized for quotation on certain automated quotation systems, provided that current price and volume information with respect to transactions in such securities is provided by the exchange or system. If we do not retain a listing on the Nasdaq Capital Market and if the price of our shares of common stock is less than $5.00, our common stock will be deemed a penny stock (meaning that our shares may be considered highly speculative and may trade infrequently, which can make them difficult to accurately price or sell). The penny stock rules require a broker-dealer, before a transaction in a penny stock not otherwise exempt from those rules, to deliver a standardized risk disclosure document containing specified information. In addition, the penny stock rules require that, before effecting any transaction in a penny stock not otherwise exempt from those rules, a broker-dealer must make a special written determination that the penny stock is a suitable investment for the purchaser and receive: (i) the purchaser’s written acknowledgment of the receipt of a risk disclosure statement; (ii) a written agreement to transactions involving penny stocks; and (iii) a signed and dated copy of a written suitability statement. These disclosure requirements may have the effect of reducing the trading activity in the secondary market for our common stock, and therefore stockholders may have difficulty selling their shares. 29 As a “smaller reporting company,” we may avail ourselves of reduced disclosure requirements, which may make our common stock less attractive to investors. We are a “smaller reporting company” under applicable SEC rules and regulations, and, as a result of the SEC’s recent amendment to the definition of “smaller reporting company,” we will continue to be a “smaller reporting company” for so long as either (i) the market value of our common stock held by non-affiliates as of the end of our most recently completed second quarter (“public float”) is less than $250 million or (ii) annual revenues of less than $100 million during the most recently completed fiscal year and (A) no public float or (B) a public float of less than $700 million. As a “smaller reporting company,” we have relied on exemptions from certain SEC disclosure requirements that are applicable to other public companies. These exemptions include reduced financial disclosure and reduced disclosure obligations regarding executive compensation. Until such time as we cease to be a “smaller reporting company,” such reduced disclosure in our SEC filings may make it harder for investors to analyze our operating results and financial prospects. If some investors find our common stock less attractive as a result of our reduced disclosure, there may be a less active trading market for our common stock and our stock price may be more volatile. Our shares of common stock are from time to time thinly traded, so stockholders may be unable to sell at or near ask prices or at all if they need to sell shares to raise money or otherwise desire to liquidate their shares. Our common stock has from time to time been “thinly-traded,” meaning that the number of persons interested in purchasing our common stock at or near ask prices at any given time may be relatively small or non-existent. This situation is attributable to a number of factors, including the fact that we are a small company that is relatively unknown to stock analysts, stock brokers, institutional investors and others in the investment community that generate or influence sales volume, and that even if we came to the attention of such persons, they tend to be risk-averse and would be reluctant to follow an unproven company such as ours or purchase or recommend the purchase of our shares until such time as we became more seasoned and viable. As a consequence, there may be periods of several days or more when trading activity in our shares is minimal or non-existent, as compared to a seasoned issuer that has a large and steady volume of trading activity that will generally support continuous sales without an adverse effect on share price. We cannot give stockholders any assurance that a broader or more active public trading market for our common stock will develop or be sustained, or that current trading levels will be sustained. ITEM 1B. UNRESOLVED STAFF COMMENTS. None. ITEM 2. PROPERTIES. We lease office space in Brooklyn, New York for our headquarters. Echo also operates a manufacturing facility located in Durant, Oklahoma. ITEM 3. LEGAL PROCEEDINGS. The information included in “Note 18 – Commitments and Contingencies” of the Company’s consolidated financial statements included elsewhere in this Annual Report is incorporated by reference into this Item. On April 14, 2021, we filed suit against Osang for breach of contract and fraud seeking damages in the amount of $12 to $15 million in U.S. District Court in the Eastern District of New York (CV 21-1990). ITEM 4. MINE SAFETY DISCLOSURES. Not applicable. 30 ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES. PART II Market Information Our common stock is listed and traded on the Nasdaq Capital Market under the symbol “SGBX.” Holders As of the close of business on April 9, 2021, there were approximately 81 holders of record of our common stock, which does not reflect those shares held beneficially or those shares held in “street” name. Accordingly, the number of beneficial owners of our common stock exceeds this number. On April 9, 2021, the closing sales price of our common stock as reported on the Nasdaq Capital Market was $4.10. Dividend Policy We have never paid any cash dividends on our common stock and do not anticipate paying cash dividends in the foreseeable future. The payment of dividends by us will depend on our future earnings, financial condition and such other business and economic factors as our management may consider relevant. Recent Sales of Unregistered Securities We did not sell any unregistered securities from January 1, 2020 through December 31, 2020 that were not previously disclosed in our filings with the SEC. Issuer Purchases of Equity Securities We did not repurchase any of our outstanding shares during 2020.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS. Introduction and Certain Cautionary Statements The following discussion and analysis of the financial condition and results of our operations should be read in conjunction with our consolidated financial statements and related notes and schedules included elsewhere in this Annual Report. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those discussed below. Factors that could cause or contribute to such differences include, but are not limited to, intensified competition and operating problems in our operating business projects and their impact on revenues and profit margins or additional factors, and those discussed in the section entitled “Risk Factors” in Part I, Item 1A of this Annual Report. In addition, certain information presented below is based on unaudited financial information. Background 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. On October 3, 2019, we entered into a Loan Agreement and Promissory Note (the “Loan Agreement”) with CPF GP, pursuant to which we agreed to loan CPF GP a principal amount of $750,000 at an annual interest rate of five percent (5%), with a maturity date of July 31, 2023. Under the Loan Agreement, as amended agreed to advance to CPF GP the first installment of the principal amount, equal to $500,000, no later than January 31, 2020 and the second installment of the principal amount, equal to $250,000, no later than April 15, 2020. As security for this loan, we will receive a security interest in all of CPF GP’s membership interests in the Licensee. If we fail to fund either principal installment, such failure will constitute a default under the Loan Agreement and a cross default under the License Agreement. On January 21, 2020, pursuant to the Loan Agreement, CPF GP issued to us a promissory note in the principal amount of $400,000 (the “Company Note”) and issued to Paul Galvin, our Chairman and CEO, a promissory note in the principal amount of $100,000 (the “Galvin Note”). The transaction closed on January 22, 2020, on which date we loaned CPF GP $400,000 and Mr. Galvin personally loaned CPF GP $100,000 on behalf of us. The Company Note and Galvin Note bear interest at five percent (5%) per annum, payable, together with the unpaid principal amount of the promissory notes, on the earlier of the July 31, 2023 maturity date or upon the liquidation, redemption sale or issuance of a dividend upon the LLC interests in CPF MF 2019-1 LLC, a Texas limited liability company of which CPF GP is the general partner; provided, that the terms of the Galvin Note provide that all interest payments due to Mr. Galvin under the Galvin Note shall be paid directly to, and for the benefit of, the Company. 32 On February 4, 2020, we entered into a Securities Purchase Agreement (the “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 is one of a series of up to $400,000 of notes that may be issued by us, 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. In March 2020, we began increasing our focus on providing our Modules as health care facilities for deployable medical response solutions. In May, we entered into a partnership with Grimshaw and Osang for deployment of our D-Tec suite of prefabricated health facilities for on-site immediate COVID-19 testing. In September we entered the U.S. test lab market by forming a joint venture with Clarity Labs, a manufacturer and market leader of rapid diagnostic tests, to launch CLIA-certified laboratories. Our joint venture with Clarity has allowed us to not only supply our D-Tec suite of prefabricated health facilities but also allows us to provide testing services at such facilities. We have supplied our building modular coronavirus testing centers and provide testing services for Los Angeles International Airport (LAX), Memorial in Wayne County, Michigan and have been selected as a Trusted Testing Partner (TTP) for Hawaii’s COVID-19 travel testing program. In September 2020, we acquired substantially all the assets of Echo, 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. 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. In November 2020, Clarity Mobile Venture, our joint venture partnership, entered into a contract with the City of Los Angeles for the operations of a COVID-19 PCR test laboratory at Los Angeles International Airport ("LAWA") to provide a full-service modular laboratory and testing facility onsite at the airport. The facility is located across from LAWA Terminal 6 and opened in December 2020. The facility administers PCR tests with results available within three hours for passengers and airline crew, and no later than 24 hours for LAWA airport employees. Additionally, other rapid coronavirus tests including antigen tests have been provided. Clarity Mobile Venture will be the primary operator of the facility. In November 2020, we and Memorial Hospital, of Michigan (“Memorial”), entered into a Professional Services and Capital Support Contract (“PSCSC”) with Wayne County, Michigan which engages the Company as a sub-contractor to render services and support to support Memorial, as the primary contractor, in connection with the fulfillment of statements of work submitted from Wayne County to Memorial to construct portable on-site laboratory facilities for COVID-19 testing. The program deploys the D-Tec Product Series designed by Grimshaw Architects and developed by SG Blocks. The D-Tec 1 Units are expected to be deployed throughout Wayne County and will provide sample extraction. Clarity Mobile Venture will be the primary operator of the facility. Results of Operations Our operations for the years ended December 31, 2020 and 2019 may not be indicative of our future operations. Years Ended December 31, 2020 and 2019: Total Revenue Total Cost of revenue Total Operating expenses Total Operating loss Total Other income (expense) Add: Net profit attributable non-controlling interests Net loss attributable to common stockholders of SG Blocks, Inc. 33 For the Year Ended December 31, 2020 For the Year Ended December 31, 2019 $ $ 8,755,623 $ (6,535,444 ) (6,803,011 ) (4,582,832 ) 74,670 184,567 (4,692,729 ) $ 2,984,835 (2,307,488 ) (7,381,359 ) (6,704,012 ) (216,528 ) — (6,920,540 ) Revenue During the year ended December 31, 2020, we derived revenue from the following three categories of sources: construction services, engineering services and medical revenue. The medical revenue segment is a new segment for the year ended December 31, 2020 that commenced when we began sales of COVID tests and includes revenue from our sales of COVID tests, revenue related to COVID-19 samples collected from our Clarity Mobile joint venture and other laboratory testing equipment sold. Total revenue for the year ended December 31, 2020 was $8,755,623 compared to $2,984,835 for the year ended December 31, 2019. This increase of $5,770,788 or 193% was primarily due to our growth in medical related projects of approximately $5,020,000 which included an increase in medical revenue of $4,241,500 from the collection of COVID-19 tests samples, the sale of COVID-19 test kits, and an increase in construction sales of $778,500 from sales of construction of laboratory and collection units. Revenue from construction services increased by a total $1,295,936 which included the increase of $778,500 discussed in the previous sentence for medical related projects and revenue increases in government projects of approximately of $750,000, special use projects of approximately $1,410,000, hospitality project of approximately $485,000, and another project of approximately $300,000. We had a decrease of approximately ($2,260,000) related to our retail and office customer types. Cost of Revenue and Gross Profit Cost of revenue was $6,535,444 for the year ended December 31, 2020, compared to $2,307,488 for the year ended December 31, 2019. The increase of $4,227,956 or 183%, is primarily related to higher procurement of COVID-19 testing supplies and medical equipment surrounding our medical customer 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. Gross profit was $2,220,179 and $677,347 for the years ended December 31, 2020 and 2019, respectively. Gross profit percentage increased to 25% for the year ended December 31, 2020 compared to 23% for the year ended December 31, 2019, primarily due to higher margins on revenue derived from our lab testing and other medical related construction contracts. We also had a single contract in the amount of $300,000 with no estimated costs in 2020. Payroll and Related Expenses Payroll and related expenses for the year ended December 31, 2020 were $2,992,207 compared to $2,392,587 for the year ended December 31, 2019. This increase was primarily caused by an increase of approximately $488,000 in stock-based compensation expense and increase in non-chargeable production salaries of approximately of $102,000 during the year ended December 31, 2020 compared to the year ended December 31, 2019. We recognized $1,204,095 in stock-based compensation expense related to payroll and related expenses for the year ended December 31, 2020, compared to $715,904 for December 31, 2019. Other Operating Expenses (General and administrative expenses, Marketing and business development expense, Pre-project expenses and Goodwill impairment) Other operating expenses (general and administrative expenses, marketing and business development expenses, pre-project expenses and goodwill impairment) for the year ended December 31, 2020 were $3,810,804 compared to $4,988,722 for the year ended December 31, 2019. The decrease was primarily due to no impairment loss recognized in 2020 compared to an impairment loss of approximately $2,938,000 in 2019, a decrease in marketing and business development costs of approximately $10,000, offset by an increase in pre-project expenses of approximately $109,000, and an increase in general and administrative expenses of $1,661,573 that included an increase in rent expenses of approximately $140,000, an increase of approximately $41,000 in depreciation expense, an increase of approximately $504,000 in legal fees, an increase of approximately $78,000 in insurance fees, an increase of approximately $96,000 in building and shop supplies, an increase in information technology expenses of approximately $52,000 and an increase of approximately $519,000 in consulting and advisory services. We recognized $57,120 in stock-based compensation expense related to legal expenses for the year ended December 31, 2020. We recognized $13,500 in stock-based compensation expense related to marketing expenses for the year ended December 31, 2019. 34 Other Income (Expense) Interest expense for the year ended December 31, 2020 was $9,275 mainly related to a 9% secured note in the principal amount of $200,000 issued on February 4, 2020 to an accredited investor. For the year ended December 31, 2019, we recognized $178,995 in interest expense related to the RedDiamond Partners LLC Securities Purchase Agreement that was executed in November 2019 and repaid in full in December 2019. Interest income for the year ended December 31, 2020 was $61,675 mainly derived from bank interest and interest associated with an outstanding note receivable and there was no interest income for the year ended December 31, 2019. For the year ended December 31, 2020, we recognized $23,282 in other income compared to $14,506 during the year ended December 31, 2019. For the year ended December 31, 2020, there was a loss on asset disposal of $1,012 compared to $52,039 for a loss from equity affiliates during the year ended December 31, 2019. Income Tax Provision A 100% valuation allowance was provided against the deferred tax asset consisting of available net operating loss carryforwards and, accordingly, no income tax benefit was provided. Impact of Inflation The impact of inflation upon our 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 we do 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. 35 Liquidity and Capital Resources As of December 31, 2020 and December 31, 2019, we had an aggregate of $13,010,356 and $1,625,671, 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 from us in full at a price to the public of $100.00 per share. 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. We incurred a total of $1,565,386 in issuance costs in connection with the Public Offering. 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 (the “Purchase Agreement”) with certain institutional investors and accredited investors. Concurrently with the sale of the common stock, pursuant to the Purchase Agreement, we also sold common stock purchase warrants to such investors to purchase up to an aggregate of 42,388 shares of common stock. We incurred $379,816 in issuance costs from the offering and issued 4,239 warrants to the underwriters. 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 (the “Underwriting Agreement”) to the public. We incurred $181,695 in issuance costs from the offering and issued warrants to purchase 2,250 shares of common stock to the underwriter. 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. We incurred a total of $454,552 in issuance costs in connection with the Public Offering. 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 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 (the “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 is one of a series of up to $400,000 of notes that may be issued by us, 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. In April 2020, we completed a public offering where we pursuant to which we issued 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. We incurred a total of approximately $347,661 in issuance costs in connection with the offering and issued no warrants to purchase shares of common stock to the underwriter. 36 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. We incurred a total of approximately $1,653,859 in issuance costs in connection with the offering and issued warrants to purchase 300,000 shares of common stock to the underwriter. We anticipate that we will continue to generate losses from operations for the foreseeable future. At December 31, 2020, we had a cash balance and short-term investment of $13,010,356. As of December 31, 2020, our stockholders’ equity was $18,253,256, compared to $4,360,149 as of December 31, 2019. Our net loss for the years ended December 31, 2020 and 2019 was $4,508,162 and $6,920,540, respectively. This decrease was primarily due to an increase in revenue and a decrease in operating expenses of $578,348, an increase of other income of $70,451 and a decrease of $169,720 in interest expenses in 2020. Net cash used in operating activities was $2,887,950 and $2,815,621 for the years ended December 31, 2020 and 2019, respectively. The increase resulted mainly from an increase of approximately $45,000 in working capital, an increase of approximately $531,000 in non-cash stock compensation expense, a decrease of non-cash goodwill impairment loss of approximately $2,938,00 that was recognized in 2019, offset by a decrease in the overall net loss of approximately $2,410,000 in the year ended December 31, 2020 compared to year ended December 31, 2019. 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. We provide services to our construction 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 December 31, 2020, we had 21 projects totaling $25,117,461 under contract, which, if they all proceed to construction, will result in us constructing approximately 232,812 square feet of modular space. Of these contracts, all twenty one (21) projects combine all three phases or parts thereof and including construction. We expect that all of this revenue will be realized by September 30, 2022. 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 increase in backlog at December 31, 2020 from the prior year is primarily attributable to two contracts during the third quarter of 2020 in the amount of approximately $4 million and approximately $2.95 million and three contracts during the fourth quarter of 2020 in the amount of approximately $2.7 million, $0.80 million and $.70 million offset by work in progress or completed contracts for the year ended 2020 for approximately $6,300,000. We expect that all of this revenue will be realized by September 30, 2022. Backlog does not include COVID tests or testing services provided through our joint venture, Clarity Mobile Venture. 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. 37 Off-Balance Sheet Arrangements As of December 31, 2020 and 2019, 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 December 31, 2020. Critical Accounting Policies and New Accounting Pronouncements Critical Accounting Policies Our financial statements are prepared in accordance with 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 consolidated financial statements included elsewhere in this Annual 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. 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. 38 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 – 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. Prior to entering into the ELA, we were subject to an agreement to construct and develop a certain property (“Original Agreement”), which now is subject to the ELA. Because of this, we are no longer obliged to perform under the Original Agreement. Upon entering the ELA, we had an outstanding accounts receivable balance of $306,143 which was forfeited and we recognized this amount as deferred contract costs. This amount was offset by $102,217, which was a reimbursement from the licensee for project costs on this project. We incurred total deferred contract costs of $203,926. We considered this amount an incremental cost of obtaining that ELA, because we expect to recover these costs through future royalty payments. We plan 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. 39 On October 9, 2019, we entered into a Right of First Refusal Agreement (the “Agreement”) with CMC Development LLC (“CMC”). See Note 3 for a discussion on the Right of First Refusal Agreement. Under the agreement, we have 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, we agreed to issue to CMC 2,500 shares of restricted stock of our common stock, of which 1,250 shares will vest and be issued on September 30, 2020 and the remaining 1,250 shares will vest and be issued on September 30, 2021, unless the Agreement is earlier terminated. In the event that the Agreement is earlier terminated, CMC will still be entitled to receive the entire amount of such restricted stock that has vested as of such earlier termination date, but in no event less than 1,250 shares of such restricted stock. The Agreement also provides for customary indemnification and confidentiality obligations between the parties. The 2,500 shares of restricted stock of our common stock has yet to be issued to CMC. The Agreement also provides that CMC has engaged us to build and design, in the aggregate, approximately 100 residential and commercial units at 1100 Ridge Avenue, Atlanta, Georgia, which is known as the “Ridge Avenue, Atlanta Project.” The total cost of the project is $16,900,000. The project is a residential project but not subject to the ELA. In May 2020, we and Osang Healthcare Co., Ltd. ("Osang"), a South Korea based global manufacturer and distributor of medical grade diagnostic tests and equipment, announced the signing of a one year, non-exclusive distributorship agreement for the United States, for OHC's "GeneFinder COVID-19 Plus RealAmp Kit." This is a test designed to detect SARS-CoV-2, the virus that causes COVID-19. The Distributorship Agreement is Osang's standard form of distributorship agreement and provides the Company with the non-exclusive right to distribute Osang's GeneFinder COVID-19 Plus RealAmp Kit in the United States for a stated term of one (1) year. An import license from the U.S. government has been issued to import and distribute the Osang test kits. There can be no assurance that the Distribution Agreement will continue and, it has not yielded the anticipated benefits or generated significant revenue, if any. The revenue from these product sales is recognized upon the transfer of control, which is at a point in time, and is generally upon shipment, Provisions for any discounts, rebates, sales concessions and returns are provided for in the period the related sale is recorded. During the year ending December 31, 2020, we recognized $250,000 in revenue related to such products, which is included in medical revenue on the accompanying consolidated statements of operations. On April 14, 2021, we filed suit against Osang for breach of contract and fraud seeking damages in the amount of $12 to $15 million in U.S. District Court in the Eastern District of New York (CV 21-1990). See Item 3. Legal Proceedings. We entered into a joint venture agreement with Clarity Lab Solutions, LLC (“Clarity Labs”) (the “JV”). Revenue from the activities of the JV is related to clinical testing services and is recognized when services have been rendered, which is at a point in time. Included in the consideration we expected to be entitled to receive, we estimate its contractual allowances, payer denials and price concessions. During the year ending December 31, 2020, we recognized $2,150,323 in revenue related to activities through the JV, which is included in medical revenue on the accompanying consolidated statements of operations. 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, SGB 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 value. Our evaluation of goodwill completed during the year ended December 31, 2020, resulted in no impairment loss. Intangible assets – Intangible assets consist of $2,766,000 of proprietary knowledge and technology, which is being amortized over 20 years. In addition, included in intangible assets is $97,164 of trademarks, and $5,300 of website costs that are being amortized over 5 years. We evaluated intangible assets for impairment during the year ended December 31, 2020, and determined that there are no impairment losses. 40 New Accounting Pronouncements See Note 3 to the accompanying consolidated financial statements for all recently adopted and new accounting pronouncements. Non-GAAP Financial Information In addition to our results under GAAP, we also present EBITDA and Adjusted EBITDA for historical periods. EBITDA and Adjusted EBITDA are non-GAAP financial measures and have been presented as supplemental measures of financial performance that are not required by, or presented in accordance with, GAAP. We calculate EBITDA as net income (loss) before interest expense, income tax benefit (expense), depreciation and amortization. We calculate Adjusted EBITDA as EBITDA before certain non-recurring adjustments such as loss on conversion of convertible debentures, change in fair value of financial instruments and stock compensation expense. EBITDA and Adjusted EBITDA are presented because they are important metrics used by management as one of the means by which it assesses our financial performance. EBITDA and Adjusted EBITDA are also frequently used by analysts, investors and other interested parties to evaluate companies in our industry. These measures, when used in conjunction with related GAAP financial measures, provide investors with an additional financial analytical framework that may be useful in assessing us and our results of operations. EBITDA and Adjusted EBITDA have certain limitations. EBITDA and Adjusted EBITDA should not be considered as alternatives to net income (loss), or any other measures of financial performance derived in accordance with GAAP. These measures also should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items for which these non-GAAP measures make adjustments. Additionally, EBITDA and Adjusted EBITDA are not intended to be liquidity measures because of certain limitations, including, but not limited to: ● ● They do not reflect our cash outlays for capital expenditures; They do not reflect changes in, or cash requirements for, working capital; and ● Although depreciation and amortization are non-cash charges, the assets are being depreciated and amortized and may have to be replaced in the future, and these non-GAAP measures do not reflect cash requirements for such replacements. Other companies, including other companies in our industry, may not use such measures or may calculate one or more of the measures differently than as presented in this Annual Report, 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. 41 The following is a reconciliation of EBITDA and Adjusted EBITDA to the nearest GAAP measure, net loss: For the Year Ended December 31, 2020 Net loss attributable to common stockholders of SG Blocks, Inc.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE. None. ITEM 9A. CONTROLS AND PROCEDURES. (a) Disclosure Controls and Procedures. Our management, with the participation of our Principal Executive Officer and Principal Financial Officer, carried out an evaluation of the effectiveness of our “disclosure controls and procedures” (as defined in Exchange Act Rules 13a-15(e) or 15d-15(e)) as of the end of the period covered by this Annual Report (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 SEC 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 consolidated financial statements and other information contained in this Annual Report present fairly, in all material respects, our business, financial condition and results of operations. (b) Management’s Annual Report on Internal Control over Financial Reporting Our management is also responsible for establishing and maintaining adequate internal control over financial reporting (as such term is defined in Rules 13a-15(f) or 15d-15(f) of the Exchange Act). The Company’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Because of the inherent limitations of internal control systems, our internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies or procedures may deteriorate. The Company does not have sufficient internal controls related to the timely closing of their accounting records, caused by insufficient accounting resources and a lack of formal review procedures. In addition, the Company does not have sufficient internal controls related to the application of technical accounting guidance to complex and/or new transactions. To assist in internal control over financial reporting two resources have been hired. Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2020. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013). Based on our assessment, we concluded that, as of December 31, 2020, our internal control over financial reporting was not effective based on those criteria. This Annual Report does not include an attestation report of our registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Company’s registered public accounting firm pursuant to the exemption provided to issuers that are neither “large accelerated filers” nor “accelerated filers” under the Dodd-Frank Wall Street Reform and Consumer Protection Act. (c) Changes in Internal Control over Financial Reporting There was no change in our internal control over financial reporting that occurred during the fourth quarter of 2020. ITEM 9B.

AND SUBSIDIARIES Consolidated Financial Statements December 31, 2020 and 2019 Table of Contents Consolidated Financial Statements Report of Independent Registered Public Accounting Firm Consolidated Balance Sheets Consolidated Statements of Operations Consolidated Statements of Changes in Stockholders’ Equity Consolidated Statements of Cash Flows Notes to Consolidated Financial Statements Page F-1 F-4 F-5 F-6 F-7 F-8 Report of Independent Registered Public Accounting Firm To the Board of Directors and Stockholders SG Blocks, Inc. and Subsidiaries Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of SG Blocks, Inc. and subsidiaries (the “Company”), as of December 31, 2020 and 2019, and the related consolidated statements of operations, changes in stockholders’ equity, and cash flows for the years then ended and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company, as of December 31, 2020 and 2019, and the results of their operations and their cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America. Basis for Opinion These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matters The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved especially challenging, subjective, or complex judgments. The communication of the critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing a separate opinion on the critical audit matters or on the accounts or disclosures to which they relate. Revenue Recognition – Determination of Estimated Costs to Complete for Contracts Recognized Over Time Description of the Matter The Company’s construction and engineering contracts generally recognize revenue over time as there is a continuous transfer of control to the customer. Approximately 54% of the Company’s revenue during the year ended December 31, 2020 was for construction and engineering contracts whereby revenue was recorded over time. F-1 The Company uses the amount of cost incurred under the contract as a measure of progress towards completion, and revenue recognized is measured principally by the costs incurred and accrued to date for each contract as a percentage of the estimated total cost for each contract at completion. Contract costs include all direct material, labor, and indirect costs related to contract performance. Changes in job performance, job conditions, estimated contract costs and profitability and final contract settlements may result in revisions to costs and income, and the effects of these revisions are recognized prospectively in the period in which the revisions are determined. This measurement and comparison process requires updates to the estimate of total costs to complete the contract, and these updates include subjective assessments and judgments. We identified the Company’s estimation of the costs to complete each contract as a critical audit matter due to the high degree of auditor judgment and the increased extent of effort that was required when performing audit procedures to evaluate the reasonableness of management’s estimates and assumptions related to the estimate of costs to complete contracts recognized over time. How We Addressed the Matter in Our Audit Our audit procedures related to forecasts of estimated costs to complete contracts recognized over time included the following, among others: • We selected a sample of contracts and obtained and inspected the executed contract and change orders to validate existence and understand the scope of each contract. • We performed a site visit near the end of the reporting period. We observed and inspected the projects in process and inquired of project managers to gain an understanding of the progress on significant projects in process. • We evaluated and tested management’s process to estimate future costs to complete contracts recognized over time. This evaluation included the consistency of management’s process and policies regarding change orders and timely costs revisions. • We evaluated management’s ability to accurately estimate future costs to complete contracts recognized over time by performing a retrospective review of prior estimates to actual results. Acquisition of Echo DCL, LLC – Fair Value of Net Assets Acquired and Contingent Consideration Description of the Matter As discussed in Note 9 to the financial statements, the Company acquired substantially all of the assets of Echo DCL, LLC (Echo) for a purchase price cash and contingent consideration, which resulted in the acquisition of property, plant and equipment and a tradename intangible asset. Management estimated the fair value of the tradename using the relief from royalty method which required management to estimate discounted cash flows with subjective assumptions of the appropriate discount rate, an appropriate royalty rate, and future revenues. The property, plant and equipment is largely comprised of equipment and buildings held for lease. The equipment was valued using a market approach, which estimates value using third-party transactions. The buildings held for lease were valued using the cost to replicate adjusted for the condition of each building. The contingent consideration was valued using a Monte Carlo Simulation, which required management to estimate future revenues, expenses, and net income. F-2 We identified the fair value of net assets acquired and contingent consideration in the Echo business combination to be a critical audit matter due to the significant judgments made by management to estimate the fair value of intangible assets, property, plant and equipment, and contingent consideration. This required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists, when performing audit procedures to evaluate the reasonableness of management’s estimates and assumptions related to the selection of discount and royalty rates, forecasts of future revenues and cash flows, as well as estimates of the cost to replicate buildings acquired. How We Addressed the Matter in Our Audit Our audit procedures related to the assumptions and forecasts used by management to estimate the fair value of intangible assets, property, plant and equipment, and contingent consideration acquired in the Echo business combination included the following, among others: • We read the executed purchase agreement and reviewed historical financial data of Echo to verify that management had identified all acquired assets and liabilities, as well as any contingent consideration. • With the assistance of our fair value specialists, we evaluated the reasonableness of the (1) valuation methodology, (2) discount rates, (3) the royalty rate, and (4) future revenue, expenses, and growth rates, including testing the source information underlying the determination of the discount rates and the royalty rate and testing the mathematical accuracy of the calculations. • We evaluated management’s ability to accurately forecast future revenues and cash flows by considering the past financial performance of Echo and current economic factors. • We visited the Echo plant and inspected the property, plant and equipment acquired to validate existence and working condition. We reviewed online sales and auction prices to independently validate the reasonableness of the fair values assigned to acquired equipment. We performed an independent calculation to estimate the cost to replicate the buildings held for lease and compared our calculation to management’s fair value. We have served as the Company’s auditor since 2016. /s/ Whitley Penn LLP Dallas, Texas April 15, 2021 F-3 SG BLOCKS, INC.

F-7 SG BLOCKS, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements For the Years Ended December 31, 2020 and 2019 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, and to become the manufacturer of the Company's core container and modular product offerings. Also during 2020, the Company entered into a joint venture, as described below and has begun to provide clinical lab testing, as well as test kit sales related to a separate distributer agreement. Reverse Stock Split On February 28, 2017, the Company effected a 1-for-3 reverse stock split of its New Common Stock and preferred stock, which has since been converted into common stock. 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 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 this Annual Report have been adjusted to reflect the reverse stock split effected in February 2020. As of December 31, 2020, the Company had 8,596,189 shares of common stock issued and outstanding. F-8 SG BLOCKS, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements For the Years Ended December 31, 2020 and 2019 2. Liquidity As of December 31, 2020, the Company had cash and cash equivalents of $13,010,356 and a backlog of approximately $25.1 million. See note 14 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: Within 1 year 1 to 2 years Thereafter Total Backlog 2020 12,261,211 12,856,250 — 25,117,461 $ $ 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 an equity offering in April 2019 and in August 2019, which resulted in net proceeds of approximately $1,136,015. See Note 15 for a discussion of these offerings. The Company completed a Securities Purchase Agreement in November 2019, which resulted in net proceeds of approximately $326,000. See Note 11 for a discussion on this Securities Purchase Agreement. The Company completed a public offering in December 2019, which resulted in net proceeds of approximately $2,117,948. The Company completed a public offering in April and May 2020, which resulted in net proceeds of approximately $1,522,339, and $15,596,141, respectively. See Note 15 for a discussion on this public offering. The Company believes that it has adequate cash balances to meet obligations coming due in the next twelve months and further intends to meet its capital needs by containing costs, 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. 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. 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. F-9 SG BLOCKS, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements For the Years Ended December 31, 2020 and 2019 3. Summary of Significant Accounting Policies Basis of presentation and principals of consolidation – The consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and the applicable rules and regulations of the United States Securities and Exchange Commission (“SEC”) and include the accounts of the Company and its wholly owned subsidiaries, SG Building Blocks, Inc., SG Residential, Inc., SG Echo, LLC and SG Blocks Puerto Rico, Inc. All intercompany balances and transactions are eliminated. Certain prior period amounts have been reclassified to conform to the current period’s presentation. Recently adopted accounting pronouncements - New accounting pronouncements implemented by the Company are discussed below or in the related notes, where appropriate. In August 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2018-13, “Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”). This ASU amends ASC 820 to add, remove and modify certain disclosure requirements for fair value measurements. For example, public companies will be required to disclose the range and weighted average of significant unobservable inputs used to develop for Level 3 fair value measurements. The Company adopted ASU 2018-13 effective January 1, 2020. The adoption of this guidance did not have a material impact on the Company's financial position, results of operations or cash flow. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This update will require the measurement of all expected credit losses for financial assets, including trade receivables, held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. The guidance was initially effective for the Company for annual reporting periods beginning after December 15, 2019 and interim periods within those fiscal years. In November 2019, the FASB issued ASU 2019-10, “Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates,” which, among other things, defers the effective date of ASU 2016-13 for public filers that are considered smaller reporting companies as defined by the SEC to fiscal years beginning after December 15, 2022, including interim periods within those years. Early adoption is permitted. The Company adopted ASU 2016-13 effective January 1, 2020. The adoption of this guidance did not have a material impact on the Company's financial position, results of operations or cash flow. Accounting estimates – The preparation of 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, warrant liabilities and allowance for doubtful accounts. Actual results could differ from those estimates. Operating cycle – The length of the Company’s contracts varies, but is typically between six to twelve months. In some instances, the length of the contract may exceed twelve months. Assets and liabilities relating to current and long-term contracts are included in current assets and current liabilities, respectively, in the accompanying balance sheets as they will be liquidated in the normal course of contract completion, which at times could exceed one year. F-10 SG BLOCKS, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements For the Years Ended December 31, 2020 and 2019 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 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 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 year ended December 31, 2020. 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 will vest and be issued on September 30, 2020 and the remaining 1,250 shares will vest and be issued on September 30, 2021, unless the Agreement is earlier terminated. In the event that the Agreement is earlier terminated, CMC will still be entitled to receive the entire amount of such restricted stock that has vested as of such earlier termination date, but in no event less than 1,250 shares of such restricted stock. The Agreement also provides for customary indemnification and confidentiality obligations between the parties. The 2,500 shares of restricted stock of the Company's common stock has yet to be issued to CMC. F-11 SG BLOCKS, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements For the Years Ended December 31, 2020 and 2019 3. Summary of Significant Accounting Policies (continued) The Agreement also provides that CMC has engaged the Company to build and design, in the aggregate, approximately 100 residential and commercial units at 1100 Ridge Avenue, Atlanta, Georgia, which is known as the “Ridge Avenue, Atlanta Project.” The total cost of the project is $16,900,000. The project is a residential project but not subject to the Company’s Exclusive License Agreement, dated October 3, 2019. In May 2020, the Company and Osang Healthcare Co., Ltd. ("Osang"), a South Korea based global manufacturer and distributor of medical grade diagnostic tests and equipment, announced the signing of a one year, non-exclusive distributorship agreement for the United States, for OHC's "GeneFinder COVID-19 Plus RealAmp Kit." This is a test designed to detect SARS-CoV-2, the virus that causes COVID-19. The Distributorship Agreement is Osang's standard form of distributorship agreement and provides the Company with the non-exclusive right to distribute Osang's GeneFinder COVID-19 Plus RealAmp Kit in the United States for a stated term of one (1) year. Pursuant to the terms of the Distributorship Agreement, the Company is required to make payment for 100% of any purchase order prior to shipment of the product from Osang, though it does not expect to make any cash outlays with respect to any product that it distributes and expects instead to require any third-party purchasers to make the necessary cash outlays as part of a purchase order entered into with the Company. The Distributorship Agreement does not guarantee the Company a specific quantity of kits to sell or a customer list, and may be terminated by either party at any time on thirty (30) days' notice. An import license from the U.S. government has been issued to import and distribute the Osang test kits. There can be no assurance that the Distribution Agreement will continue, and it has not yielded the anticipated benefits or generated significant revenue, if any. The revenue from these product sales is recognized upon the transfer of control, which is at a point in time, and is generally upon shipment, Provisions for any discounts, rebates, sales concessions and returns are provided for in the period the related sale is recorded. During the year ending December 31, 2020, the Company recognized $250,000 in revenue related to such products, which is included in medical revenue on the accompanying consolidated statements of operations. As described below, the Company entered into a joint venture agreement with Clarity Lab Solutions, LLC (“Clarity Labs”) (the “JV”). Revenue from the activities of the JV is related to clinical testing services and is recognized when services have bene rendered, which is at a point in time. Included in the consideration the Company expected to be entitled to receive, the Company estimates its contractual allowances, payer denials and price concessions. During the year ending December 31, 2020, the Company recognized $2,150,323 in revenue related to activities through the JV, which is included in medical revenue on the accompanying consolidated statements of operations. Disaggregation of Revenues The Company’s revenues are principally derived from construction and engineering contracts related to Modules, and medical revenue derived from lab testing and test kit sales. Our contracts are with customers in various industries. Revenue recognized at a point in time and recognized over time were $4,057,086 and $4,698,537, respectively, for the year ending December 31, 2020. All revenue recognized for the year ending December 31, 2019 was over time. F-12 SG BLOCKS, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements For the Years Ended December 31, 2020 and 2019 3. Summary of Significant Accounting Policies (continued) The following tables provide further disaggregation of the Company’s revenues by categories: Twelve Months Ended December 31, Revenue by Customer Type Government Hospitality Multi-Family Medical (lab testing, test kit sales and equipment) Medical (construction services) Office Retail School Special Use Other (1) Total revenue by customer type 2020 $ $ 751,697 487,111 126,222 4,241,500 778,883 191,505 427,444 36,500 1,414,761 300,000 8,755,623 9% $ 6% 1 % 49% 9% 2 % 5 % — % 16% 3% 100 % $ 2019 — — 94,178 — — 1,468,734 1,413,669 — 6,812 1,442 2,984,835 —% —% 3 % —% —% 49% 48% —% —% —% 100 % (1) Construction fee of $300,000 with no cost of revenue during 2020. Contract Assets and Contract Liabilities Accounts receivable are recognized in the period when the Company’s right to consideration is unconditional and billed to the customer. Accounts receivable are recognized net of an allowance for doubtful accounts. A considerable amount of judgment is required in assessing the likelihood of realization of receivables. The timing of revenue recognition may differ from the timing of invoicing to customers. Contract assets include unbilled amounts from long-term construction services when revenue recognized under the cost-to-cost measure of progress exceeds the amounts invoiced to customers, as the amounts cannot be billed under the terms of our contracts. Such amounts are recoverable from customers based upon various measures of performance, including achievement of certain milestones, completion of specified units or completion of a contract. Contract assets are generally classified as current within the 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 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. F-13 SG BLOCKS, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements For the Years Ended December 31, 2020 and 2019 3. Summary of Significant Accounting Policies (continued) 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 a 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 amortizes 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 December 31, 2020, accumulated amortization related to deferred contract costs amounted to $50,981. During the year ended December 31, 2020, amortization expense relating to the deferred contract costs amounted to $40,786 and is included in general and administrative expenses on the accompanying consolidated statements 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 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). 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, $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. 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. F-14 SG BLOCKS, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements For the Years Ended December 31, 2020 and 2019 3. Summary of Significant Accounting Policies (continued) 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 Labs. In consideration and subject to Clarity Lab’s services and commitments and provided the agreement remains valid and in force, and is not terminated, SGB shall issue 200,000 restricted shares of SGB common stock to be earned over a defined vesting period starting in December 1, 2020. As of December 31, 2020, no shares were issued. 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 December 31, 2020, $965,561 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 year ended December 31, 2020, the Company recognized revenue of $641,178 to Clarity Labs, of which $420,773 is included in accounts receivable as of December 31, 2020. 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 $13,010,356 and $1,625,671 for the years ended December 31, 2020 and 2019, respectively. Short-term investment – The Company classifies its investment 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 December 31, 2020 or 2019, respectively. Accounts receivable and allowance for doubtful accounts – Accounts receivable are receivables generated from sales to customers and progress billings on performance type contracts. Amounts included in accounts receivable are deemed to be collectible within the Company’s operating cycle. The Company recognizes account receivable at invoiced amounts. The allowance for doubtful accounts reflects the Company's best estimate of probable losses inherent in the accounts receivable balances. Management provides an allowance for doubtful accounts based on the Company’s historical losses, specific customer circumstances, and general economic conditions. Periodically, management reviews accounts receivable and adjusts the allowance based on current circumstances and charges off uncollectible receivables when all attempts to collect have been exhausted and the prospects for recovery are remote. Recoveries are recognized when they are received. Actual collection losses may differ from our estimates and could be material to our 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 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. There was no inventory for December 31, 2019. F-15 SG BLOCKS, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements For the Years Ended December 31, 2020 and 2019 3. Summary of Significant Accounting Policies (continued) 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 . 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, included in intangible assets is $97,164 of trademarks, and $5,300 of website costs that are being amortized over 5 years. The Company evaluated intangible assets for impairment during the year ended December 31, 2020, and determined that there are no impairment losses. The accumulated amortization and amortization expense as of and for the year ended December 31, 2020 was $649,855 and $148,541, respectively. The accumulated amortization and amortization expense as of and for the year ended December 31, 2019 was $1,614,315 and $145,124 respectively. The estimated amortization expense for the successive five years is as follows: For the year ending December 31,: 2021 2022 2023 2024 2025 Thereafter $ $ 158,793 154,470 152,676 151,969 148,551 1,452,150 2,218,609 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. F-16 SG BLOCKS, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements For the Years Ended December 31, 2020 and 2019 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 Level 2 Level 3 Quoted prices in active markets for identical assets or liabilities. Quoted prices for similar assets and liabilities in active markets or inputs that are observable. Inputs that are unobservable (for example, cash flow modeling inputs based on assumptions). The earnout liability represents the only financial liability measured at fair value on a recurring basis as of December 31, 2020 and was a level 3 asset. As of December 31, 2020, the estimated value of the earnout liability was zero. Transfer into and transfers out of the hierarchy levels are recognized as if they had taken place at the end of the reporting period. There were no transfers into or out of the hierarchy levels during the year ended December 31, 2020 or 2019, besides the transfer in of the earnout liability. 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 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. F-17 SG BLOCKS, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements For the Years Ended December 31, 2020 and 2019 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 December 31, 2020 and 2019, 79% and 92%, respectively, of the Company’s gross accounts receivable were due from three and one customers. Revenue relating to three and two customers represented approximately 61% and 78% of the Company’s total revenue for the years ended December 31, 2020 and 2019, respectively. For the year ended December 31, 2020, there were no vendors which represented 10% or more of our cost of revenue. For the year ended December 31, 2019, 74% of our cost of revenue related to three vendors. 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 December 31, 2020 and 2019, the Company’s accounts receivable consisted of the following: Billed: Construction services Engineering services Medical revenue Retainage receivable Other receivable Total gross receivables Less: allowance for doubtful accounts Total net receivables 2020 2019 $ $ 1,391,555 $ 86,264 1,157,819 615,136 180,748 3,431,522 (795,914) 2,635,608 $ 1,321,575 14,594 — 544,911 6,000 1,887,080 (785,895) 1,101,185 Receivables are evaluated for collectability and allowances for potential losses are established or maintained on applicable receivables. The allowance for doubtful accounts was $795,914 as of December 31, 2020. There was a provision for doubtful accounts of $10,018, and no write offs for the year ended December 31, 2020. There was no provision for doubtful accounts and write offs were $54,000 for the year ended December 31, 2019. F-18 SG BLOCKS, INC.

The Company periodically evaluates and revises its estimates and makes adjustments when they are considered necessary. 6. Property, plant and equipment Property, plant and equipment are stated at cost less accumulated depreciation and amortization and depreciated using the straight-line method over their useful lives. At December 31, 2020 and 2019, the Company’s property, plant and equipment, net consisted of the following: Computer equipment and software Furniture and other equipment Leasehold improvements Equipment and machinery Automobiles Building held for lease Laboratory and temporary units Property, plant and equipment Less: accumulated depreciation Property, plant and equipment, net 2020 2019 $ $ 73,991 $ 11,593 6,071 1,127,647 4,638 501,336 1,016,238 2,741,514 (58,500 ) 2,683,014 $ 18,862 1,885 — — — — — 20,747 (9,000) 11,747 Depreciation expense for the years ended December 31, 2020 and 2019 amounted to $50,655 and $9,621, respectively.

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, 2021 2022 2023 2024 2025 Total lease payments Less: Imputed interest Present value of lease liabilities Operating Financing $ $ 348,117 $ 348,984 330,300 324,000 243,000 1,594,401 108,206 1,486,195 $ 20,160 $ 20,160 11,760 — — 52,080 2,027 50,053 $ Total 368,277 369,144 342,060 324,000 243,000 1,646,481 110,233 1,536,248 Operating leases for office space and the plant, with total lease payments of $1,683,000, has been leased from an affiliate of the sellers of Echo. 11. Convertible Debentures On November 12, 2019, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with an investor, pursuant to which the Company issued to the investor a senior secured convertible debenture in the principal amount of $480,770 (the “Debenture”) for proceeds of $375,000 (representing an original issue discount of 22%). The Company received net proceeds of approximately $326,250 after deducting certain fees due to the placement agent and certain transaction expenses. The Debenture was due 110 days after issuance and was secured under a Security Agreement, dated November 12, 2019, entered into with the investor (the “Security Agreement”) by a security interest in all of the Company’s existing and future assets, subject to existing security interests and exceptions. The Company had the right to redeem all or a portion of the outstanding principal of the Debenture (i) prior to the maturity date without interest and with no conversion by the investor and (ii) after the maturity date at a premium of 120%, and with interest accruing at 24% from the maturity date. As of December 13, 2019 the Debenture was paid back in full to the investor. F-22 SG BLOCKS, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements For the Years Ended December 31, 2020 and 2019 The Debenture was convertible into shares of the Company’s common stock only upon (i) the occurrence of an Event of Default (as defined in the Debenture) or (ii) at maturity in the event any principal remains outstanding, at a conversion price equal to the lower of (x) 67.5% of the lowest daily VWAPs of the common stock during the five consecutive trading days immediately preceding the Event of Default or date of maturity or (y) if the Debenture was not fully paid as of the Maturity, the lowest daily VWAP during the ten (10) consecutive trading days immediately preceding the date of the applicable Conversion, and based on a conversion amount determined by the product of (x) the portion of the principal and accrued interest to be converted and (y) 120% or (y) if the Debenture was not fully paid as of the Maturity Date and no conversions have been effected under the Debenture, the lowest daily VWAP during the ten (10) consecutive Trading Days immediately preceding the date of the applicable Conversion; provided, however, that the Company will not issue any shares of common stock upon conversion of the Debenture if the investor would exceed the aggregate number of shares of common stock which the Company may issue upon conversion or exercise (as the case may be) of the Debenture without breaching the Company’s obligations under the rules or regulations of the Nasdaq Stock Market, including rules related to the aggregate of offerings under NASDAQ Listing Rule 5635(d) (which currently limit such issuance to 60,048 shares, which is 19.99% of the Company’s outstanding shares as of the date hereof). In addition, subject to limited exceptions, the investor did not have the right to convert any portion of the Debenture if the investor, together with its affiliates, would beneficially own in excess of 4.99% of the number of shares of the Company’s common stock outstanding immediately after giving effect to its conversion and under no circumstances could convert the Debenture if the investor, together with its affiliates, would beneficially own in excess of 9.99% of the number of shares of the Company’s common stock outstanding immediately after giving effect to its conversion. In connection with this transaction, the Company entered into a Placement Agency Agreement (the “Placement Agency Agreement”) with ThinkEquity, a division of Fordham Financial Management, Inc. (the “Placement Agent”), pursuant to which the Company agreed to pay the Placement Agent a cash fee equal to 9% of the gross proceeds received by the Company from the investor in this transaction, as well as a one-time expense fee of $15,000 for aggregate out-of-pocket expenses incurred collectively in this transaction. Pursuant to the Placement Agency Agreement, the Company also agreed to grant to the Placement Agent or its designees warrants to purchase up to 9% of the aggregate number of shares of common stock underlying the Debenture, which equals 5,404 shares of common stock, at an exercise price of 110% of the closing price of the Company’s common stock on the closing date (the “Placement Agent Warrants”). The Placement Agent Warrants wereexercisable, in whole or in part, commencing on the issuance date and have an exercise period of five years. In the event that there was not an effective registration statement permitting for the resale of the shares underlying the Placement Agent Warrants, the Placement Agent Warrant’s were exercisable on a cashless basis. There were significant restrictions pursuant to FINRA Rule 5110 against transferring the Placement Agent’s Warrants and the shares issuable upon exercise of the Placement Agent Warrants during the one hundred eighty (180) days after the closing date. On December 10, 2019, the Company and ThinkEquity entered into a waiver agreement (“Waiver of Warrant”) pursuant to which ThinkEquity surrendered its rights to a warrant previously issued to ThinkEquity on November 12, 2019 to purchase 5,404 shares of the Company’s common stock as compensation for acting as placement agent for the private placement of the Debenture. 12. Income Taxes The Company’s provision (benefit) for income taxes consists of the following for the year ended December 31, 2020 and 2019: Deferred: Federal State and local Total deferred Total provision (benefit) for income taxes Less: valuation reserve Income tax provision 2020 2019 $ $ (974,181) $ (567,767) (1,541,948) (1,541,948) 1,541,948 — $ (828,472) 564,363 (264,109) (264,109) 264,109 — A reconciliation of the federal statutory rate to 0% for the year ended December 31, 2020 and 2019 to the effective rate for income from operations before income taxes is as follows: F-23 SG BLOCKS, INC.

During 2020 certain adjustments were made to the Company’s net operating loss carryforward tax asset for IRC Section 382 limitations. The valuation allowance increased by $1,541,948 and $264,109 during 2020 and 2019, respectively. As of December 31, 2020, the Company had a net operating loss carryforward of approximately $16.6 million for Federal and State tax purposes. The net operating loss expires beginning 2030 through 2037 for those losses generated in 2017 and prior years. Approximately $5.5 million of such net operating losses will carryforward indefinitely and be available to offset up to 80% of future taxable income each year. Subsequent to December 31, 2019, the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was passed, which temporarily removes such 80% limitation for years 2019 and 2020. The Company’s net operating loss carryforward may be subject to annual limitations, which could reduce or defer the utilization of the losses as a result of an ownership change as defined in Section 382 of the Internal Revenue Code. As required by the provisions of ASC 740, the Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more likely than not threshold, the amount recognized in the consolidated financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. Differences between tax positions taken or expected to be taken in a tax return and the net benefit recognized and measured pursuant to the interpretation are referred to as “unrecognized benefits.” A liability is recognized (or amount of net operating loss or amount of tax refundable is reduced) for an unrecognized tax benefit because it represents an enterprise’s potential future obligation to the taxing authority for a tax position that was not recognized as a result of applying the provisions of ASC 740. The Company recognizes interest and penalties related to uncertain tax positions in general and administrative expenses. As of December 31, 2020, the Company has no unrecognized tax positions, including interest and penalties. The tax years 2017 - 2019 are still open to examination by the major tax jurisdictions in which the Company operates. The Company files returns in the United States Federal tax jurisdiction and various other state jurisdictions. F-24 SG BLOCKS, INC.

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 December 31, 2020, there were options, including options granted to non-employees and non-directors, restricted stock units and warrants to purchase 36,436, 884,343 and 353,190 shares of common stock, respectively, outstanding that could potentially dilute future net income per share. Because the Company had a net loss as of December 31, 2020, 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 December 31, 2019, there were options, including options to non-employees and non-directors, restricted stock units and warrants to purchase 53,170, 21,859 and 53,189 shares of common stock, respectively, outstanding that could potentially dilute future net income per share. 14. Construction Backlog The following represents the backlog of signed construction and engineering contracts in existence at December 31, 2020 and 2019, which represents the amount of revenue the Company expects to realize from work to be performed on uncompleted contracts in progress and from contractual agreements in effect at December 31, 2020 and December 31, 2019, respectively, on which work has not yet begun: Balance - beginning of period New contracts and change orders during the period Adjustments and cancellations, net Subtotal Less: contract revenue earned during the period Balance - end of period 2020 17,634,261 $ 13,816,785 (27,370) 31,423,676 (6,306,215) 25,117,461 $ 2019 97,657,379 17,659,053 (94,697,336) 20,619,096 (2,984,835) 17,634,261 $ $ Backlog at December 31, 2020 included one large contract entered into by the Company during the third quarter of 2019 in the amount of approximately $17 million, and entered into two contracts during the third quarter of 2020 in the amount of approximately $4 million and approximately $2.95 million. The Company expects that all of this revenue will be realized by September 30, 2022. During the second quarter of 2019, the Company moved a $25.0 million contract out of backlog after receiving a cancellation notice from the customer. During the third quarter of 2019, the Company removed two contracts in the amount of $55 million and $15 million out of backlog due to the fact that these projects fall under the exclusive license agreement (“ELA”) executed during the fourth quarter of 2019. 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 June 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 entered into three contracts during the fourth quarter of 2020 in the amount of approximately $2.7 million, $0.80 million, and $0.70 million. The Company’s remaining backlog as of December 31, 2020 represents the remaining transaction price of firm contracts for which work has not been performed and excludes unexercised contract options. The Company expects to satisfy its backlog which represents the remaining unsatisfied performance obligation on contracts as of December 31, 2020 over the following period: F-25 SG BLOCKS, INC.

Backlog is adjusted to reflect any known project cancellations, revisions to project scope and cost and project deferrals, as appropriate. 15.

AND SUBSIDIARIES Notes to Consolidated Financial Statements For the Years Ended December 31, 2020 and 2019 18. Commitments and Contingencies Legal Proceedings The Company is subject to certain claims and lawsuits arising in the normal course of business. The Company assesses liabilities and contingencies in connection with outstanding legal proceedings utilizing the latest information available. Where it is probable that the Company will incur a loss and the amount of the loss can be reasonably estimated, the Company records a liability in our consolidated financial statements. These legal accruals may be increased or decreased to reflect any relevant developments on a quarterly basis. Where a loss is not probable or the amount of the loss is not estimable, the Company does not record an accrual, consistent with applicable accounting guidance. Based on information currently available, advice of counsel, and available insurance coverage, the Company believes that the established accruals are adequate and the liabilities arising from the legal proceedings will not have a material adverse effect on the consolidated financial condition. However, that in light of the inherent uncertainty in legal proceedings there can be no assurance that the ultimate resolution of a matter will not exceed established accruals. As a result, the outcome of a particular matter or a combination of matters may be material to the results of operations for a particular period, depending upon the size of the loss or the income for that particular period. Pizzarotti Litigation - On or about August 10, 2018 Pizzarotti, LLC filed a complaint against the Company and Mahesh Shetty, the Company’s former President and CFO, and others, seeking unspecified damages for an alleged breach of contract by the Company and another entity named Phipps & Co. (“Phipps”). The lawsuit was filed as Pizzarotti, LLC. v. Phipps & Co., et al., Index No. 653996/2018 and commenced in the Supreme Court of the State of New York for the County of New York. On or about April 1, 2019, Phipps filed cross-claims against the Company and Mr. Shetty asserting claims for indemnification, contribution, fraud, negligence, negligent misrepresentation, and breach of contract. SG Blocks has likewise cross claimed against Phipps for indemnification and contribution, claiming that any damages to the Plaintiff were the result of the acts or omissions of Phipps and its principals. Pizzarotti’s suit arose from a contract dated April 3, 2018 that it executed with Phipps whereby Pizzarotti, a construction manager, engaged Phipps to perform stone procuring and tile work at a construction project located at 161 Maiden Lane, New York 10038. Pizzarotti’s claims against the Company arise from a purported assignment agreement dated August 10, 2018, whereby Pizzarotti claims that the Company agreed to assume certain obligations of Phipps under a certain trade contract between Pizzarotti and Phipps & Co. Phipps’ claims against the Company arise from a purported Assignment Agreement, dated as of May 30, 2018, between Pizzarotti, Phipps and the Company (the “Assignment Agreement”), pursuant to which, it is alleged, that the Company agreed to provide a letter of credit in connection with the sub-contracted work to be provided by Phipps to Pizzarotti. The Company believes that the Assignment Agreement was void for lack of consideration and moved to dismiss the case on those and other grounds. On June 17, 2020, the New York Supreme Court entered an order dismissing certain claims against the Company brought by cross claimant Phipps & Co. Specifically, the court dismissed Phipps’ claims for indemnification, contribution, fraud, negligence and negligent misrepresentation. The court did not dismiss Phipps’ claim for breach of the Assignment Agreement. The issue of the validity of the Assignment Agreement, and the Company’s defenses to the claims brought by the plaintiff Pizzarotti, and cross claimant Phipps, are being litigated. The Company maintains that the Assignment Agreement, to the extent valid and enforceable, was properly terminated and/or there are no damages, and, consequently, that the claims brought against the Company are without merit. The Company intends to 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 has opposed both motions and the Court has yet to rule on the same. Pending the Court’s ruling on said motions discovery in the matter has been temporarily stayed. 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.

Teton Buildings, LLC (i) On January 1, 2019, SG Blocks commenced an action against Teton Buildings, LLC (“Teton”) in Harris County, Texas (“Teton Action”) to recover approximately $2,100,000 arising from defendant’s breach of the operative contract related to Heart of Los Angeles construction project in Los Angeles (the “HOLA Project”). The Petition brought claims of breach of contract, negligence, and breach of express warranty. The Firm did not represent the Company in connection with the Teton Action. (ii) On or about September 12, 2018, the Company entered into a Firm Price Quote and Purchase (the “GVL Contract”) with Teton to govern the manufacture and provision of 23 shipping containers and modular units (the “Teton GVL Modules”) for the Four Oaks Gather GVL project in South Carolina (the “GVL Project.”). The Company maintains that Teton breached the GVL Contract by (i) failing to timely deliver the Teton GVL Modules, (ii) delivering Teton GVL Modules that were defective in their design and manufacture, (iii) otherwise failed to meet South Carolina Building Code regulations and (iv) breached applicable warranties. As a result of the breach and defects in performance, design and manufacture by Teton, Company asserts that it has sustained approximately $761,401.66 in actual and consequential damages, excluding attorney’s fees. On October 16, 2019, Teton filed for Chapter 11 in the United States Bankruptcy Court for Southern District of Texas, Houston Division styled In re: Teton Buildings, LLC and bearing the case number 19-35811. The Firm was engaged to file a proof of claim in the Teton Bankruptcy. On February 11, 2020, the Company filed a proof of claim again Teton in the amount of $2,861,401.66 arising from the HOLA Project and the GVL Contract. On or about March 16, 2020, the Bankruptcy Court converted Teton’s Chapter 11 reorganization case to a Chapter 7 liquidation case. On July 18, 2019, Ronald Sommers, the Chapter 7 Trustee, filed a Report of No Distribution stating that there is no property available for distribution to creditors. On August 20, 2019, the Bankruptcy Court closed the Teton bankruptcy case. As such, there is no prospect of any recovery against Teton. On January 22, 2021, the Company filed a third-party complaint against Teton in the United States District Court for the Central District of California, Case No. 2:20-cv-03432 (“Teton Action”), seeking to determine Teton’s liability in its capacity as a bankruptcy debtor in order to collect any damages payable from Teton’s liability insurance carrier or carriers. 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. 2. SG Blocks, Inc. v HOLA Community Partners, et. al. On April 13, 2020, Plaintiff SG Blocks, Inc. (“SG Blocks”) filed a Complaint against HOLA Community Partners (“HCP”), Heart of Los Angeles Youth, Inc. (“HOLA”) (HCP and HOLA are collectively referred to as the “HOLA Defendants”), and the City of Los Angeles (“City”) in the United States District Court for the Central District of California, Case No. 2:20-cv-03432-ODW (“HOLA Action”). The Company asserted seven claims against HOLA Defendants arising out of and related to the HOLA Project, to wit, for: (1) breach of contract; (2) conversion; (3) default and judicial foreclosure under the Agreement as a security agreement; (4) misappropriation of trade secrets under California Civil Code section 3426; (5) misappropriation of trade secrets under 18 U.S.C. § 1836; and (6) intentional interference with contractual relations. On April 20, 2020, HOLA filed a separate action against the Company in the Los Angeles Superior Court arising out of the HOLA Project, asserting claims of (1) negligence; (2) strict products liability; (3) strict products liability, (4) breach of contract; (5) breach of express warranty; (6) violation of Business and Professions Code § 7031(b); and (7) violation of California’s unfair competition law, Business and Professions Code section 17200 (“UCL”) (“HOLA State Court Action”). The HOLA State Court Action was removed to the Central District of California and consolidated with the HOLA Action. On January 22, 2021, the Company filed a Third-Party Complaint in the HOLA Action against Third-Party Defendants Teton Buildings, LLC, Avesi Construction, LLC, and American Home Building and Masonry Corp (“AHB”) for indemnity and contribution with respect to HOLA’s claims. The Company has also notified its general liability carrier Sompo International regarding coverage concerning HOLA’s claims On February 25, 2021, the Court entered an order dismissing the Company’s claims for (1) breach of contract; (2) conversion; (3) default and judicial foreclosure under the Agreement as a security agreement; (4) misappropriation of trade secrets under California Civil Code section 3426; (5) misappropriation of trade secrets under 18 U.S.C. § 1836; but denied dismissal of the Company’s claims for intentional interference with contractual relations. The Court also denied the Company’s motion to dismiss HOLA’s claims. The case is currently entering the discovery stage and a trial date has been set for March 22, 2022. 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 outcome or possible recovery or loss or range of loss, if any, associated with the resolution of this litigation, and, accordingly, the Company has made no provision related to this matter in the condensed consolidated financial statements. 3. SG Blocks, Inc. v. EDI International, PC.- On June 21, 2019, SG Blocks filed a lawsuit against EDI International, PC, a New Jersey corporation, in connection with the parties' consulting agreement, dated June 29, 2016, pursuant to which EDI International, PC, was to provide, for a fee, certain architectural and design services for the HOLA Project. SG Blocks, Inc. claims that EDI International, PC, tortiously interfered with SG Blocks, Inc's economic relationship with HOLA Community Partners and Heart of Los Angeles Youth, Inc. EDI International, PC, filed a cross-complaint for alleged unpaid fees and tortious interference with EDI International, PC's contractual relationship with HOLA Community Partners and Heart of Los Angeles Youth, Inc. EDI International, PC's cross-complaint seeks in excess of $30,428.71 in damages. On July 8, 2020, SG Blocks, Inc. added PVE LLC as a defendant in the lawsuit, claiming PVE LLC is liable to the same extent as EDI International, PC. The case is currently in the discovery stage and a trial date has been set for May 2, 2022. 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 outcome or possible recovery or loss or range of loss, if any, associated with the resolution of this litigation, and, accordingly, the Company has made no provision related to this matter in the condensed consolidated financial statements. Other Litigation 1. Shetty v. SG Blocks, Inc. et. al., Case No. 20-CV-00550, United States District Court, Eastern District of New York. On January 31, 2020, Mahesh Shetty, the Company’s former President and Chief Financial Officer (“Former Employee”), filed suit against the Company and its Chairman and Chief Executive Officer, Paul Galvin, claiming (i) $372,638 in unpaid wages and bonuses and (ii) $300,000 due in severance (hereafter the “Action”). On March 25, 2020, the Former Employee filed an amended complaint raising additional claims of retaliation under the Fair Labor Standards Act, 29 U.S.C. §201 et. seq. (“FLSA”), and contractual indemnification. On April 27, 2020, the Company filed a motion to dismiss the Action. The Company asserted that the Former Employee agreed to accept (and did receive) restricted stock units of the Company’s common stock in full satisfaction and payment of all alleged unpaid wages and bonuses that are claimed in the Action, and/or has otherwise been paid in full for all amounts claimed. The Company further maintained that the Former Employee’s employment agreement precludes any entitlement to or liability for severance. On June 15, 2020, the Court entered a decision granting in part and denying in part the Company’s motion to dismiss. Specifically, the Court dismissed the Former Employee’s claim (i) for severance (in the amount of $300,000) and unpaid wages pursuant to the FLSA, but denied dismissal of the Former Employee’s claims for retaliation under the FLSA or unpaid wages allegedly due under the New York Labor Law. The parties are in the middle of pre-trial discovery, having served discovery requests upon each other but have yet to respond to same or to schedule depositions of the parties (and/or third party witnesses). No trial date has been set. 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 outcome or possible recovery or loss or range of loss, if any, associated with the resolution of this litigation, and, accordingly, the Company has made no provision related to this matter in the condensed consolidated financial statements. 2. SG Blocks, Inc. v. Osang Healthcare Company, Ltd., On April 14, 2021, the Company commenced an action against Osang Healthcare Company, Ltd. (“Osang”) in the United States District Court, Eastern District of New York, Case No. 21-01990 (“Osang Action”) .

The Company has also asserted that Osang breached the covenant of good faith and fair dealing, fraudulently induced it to enter into the MSA, and violated §349 of the New York General Business Law’s prohibition of deceptive business practices. 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 outcome or possible recovery, 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.

F-33 DESCRIPTION OF SECURITIES REGISTERED PURSUANT TO SECTION 12 OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED Exhibit 4.8 SG Blocks, Inc. (the “Company,” “we,” “us,” and “our”) had one class of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which is our common stock, par value $0.01 per share (the “common stock”). General The following is a description of the material terms of our common stock. This is a summary only and does not purport to be complete. It is subject to and qualified in its entirety by reference to our Amended and Restated Certificate of Incorporation, as amended (the “Certificate of Incorporation”), and our Amended and Restated Bylaws (the “Bylaws”). We encourage you to read our Certificate of Incorporation, our Bylaws and the applicable provisions of the Delaware General Corporation Law (the “DGCL”), for additional information. Description of Common Stock Authorized Shares of Common Stock. We currently have authorized 25,000,000 shares of common stock. Voting. Holders of our common stock are entitled to one vote for each share held of record on each matter submitted to a vote of stockholders, including the election of directors, and do not have cumulative voting rights. Our directors are elected by a plurality of the votes cast by the stockholders entitled to vote at our annual meeting of stockholders. Dividends. Subject to the prior rights of any class or series of preferred stock which may from time to time be outstanding, if any, holders of our common stock are entitled to receive dividends ratably when, as and if declared by our Board of Directors, out of funds legally available for that purpose. We have not paid any dividends on our common stock and none are contemplated in the foreseeable future. We anticipate that all earnings that may be generated from our operations will be used to finance our growth. Liquidation. Upon our liquidation, dissolution or winding up, holders of our common stock are entitled to share ratably in all assets remaining after payment of liabilities and payment of accrued dividends and liquidation preferences on the preferred stock, if any. Rights and Preferences. The holders of our common stock have no preemptive, subscription or redemption rights pertaining to our common stock and have no rights to convert their common stock into any other securities. The absence of preemptive rights could result in a dilution of the interest of the existing stockholders should additional shares of our common stock be issued. In addition, the rights of holders of our common stock are subject to, and may be adversely affected by, the rights of holders of shares of any series of preferred stock that we may designate and issue in the future. See “Risk Factors” section in the Form 10-K for a further description of risks related to our common stock. Fully Paid and Nonassessable. All of our issued and outstanding shares of common stock are fully paid and nonassessable. Anti-Takeover Effects of Delaware Law and Our Certificate of Incorporation and Bylaws Certain provisions of Delaware law, our Certificate of Incorporation and our Bylaws contain provisions that could have the effect of delaying, deferring or discouraging another party from acquiring control of us. These provisions, which are summarized below, are expected to discourage certain types of coercive takeover practices and inadequate takeover bids. These provisions are also designed, in part, to encourage persons seeking to acquire control of us to first negotiate with our Board of Directors. We believe that the benefits of increased protection of our potential ability to negotiate with an unfriendly or unsolicited acquirer outweigh the disadvantages of discouraging such proposals, including proposals that are priced above the then-current market value of our common stock, because, among other reasons, such negotiation could result in an improvement of the terms of such proposals. Certificate of Incorporation and Bylaws Certain provisions set forth in our Certificate of Incorporation, our Bylaws and in Delaware law, which are summarized below, may be deemed to have an anti-takeover effect and may delay, deter or prevent a tender offer or takeover attempt that a stockholder might consider to be in its best interests, including attempts that might result in a premium being paid over the market price for the shares held by stockholders. Proposals of business and nominations. Our Bylaws generally regulate proposals of business and nominations for election of directors by stockholders. In general, Section 3.16 requires stockholders intending to submit proposals or nominations at a stockholders meeting to provide the Company with advance notice thereof, including information regarding the stockholder proposing the business or nomination as well as information regarding the proposed business or nominee. Section 3.16 provides a time period during which business or nominations must be provided to the Company that will create a predictable window for the submission of such notices, eliminating the risk that the Company finds a meeting will be contested after printing its proxy materials for an uncontested election and providing the Company with a reasonable opportunity to respond to nominations and proposals by stockholders. Blank Check Preferred Stock. Our Board of Directors has the right to issue preferred stock in one or more series and to determine the designations, rights, preferences of such preferred stock without stockholder approval. Board Vacancies. Our Bylaws generally provide that only the board of directors (and not the stockholders) may fill vacancies and newly created directorships. While the foregoing provisions of our Certificate of Incorporation, Bylaws and Delaware law may have an anti-takeover effect, these provisions are intended to enhance the likelihood of continuity and stability in the composition of the Board of Directors and in the policies formulated by the Board of Directors and to discourage certain types of transactions that may involve an actual or threatened change of control. In that regard, these provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. The provisions also are intended to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit fluctuations in the market price of our common stock that could result from actual or rumored takeover attempts. Such provisions also may have the effect of preventing changes in our management. Delaware Anti-Takeover Statute We are subject to the provisions of Section 203 of the DGCL (“Section 203”) regulating corporate takeovers. In general, Section 203 prohibits a publicly-held Delaware corporation from engaging, under certain circumstances, in a business combination with an interested stockholder for a period of three years following the date the person became an interested stockholder unless: ● ● ● prior to the date of the transaction, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder; upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding, the outstanding voting stock owned by the interested stockholder, (1) shares owned by persons who are directors and also officers and (2) shares owned by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or at or subsequent to the date of the transaction, the business combination is approved by the board of directors of the corporation and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock which is not owned by the interested stockholder. Generally, a business combination includes a merger, asset, stock sale or other transaction resulting in a financial benefit to the interested stockholder. An interested stockholder is a person who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, did own 15% or more of a corporation’s outstanding voting stock. We expect the existence of Section 203 to have an anti-takeover effect with respect to transactions our Board of Directors does not approve in advance. We also anticipate that Section 203 may discourage business combinations or other attempts that might result in a premium over the market price for the shares of common stock held by our stockholders.
