NOTE 1 – Summary of Significant Accounting Policies

Nature of Business –On September 13, 2010 Sigma Labs, Inc., formerly named Framewaves, Inc., a Nevada corporation, acquired 100% of the shares of B6 Sigma, Inc. by exchanging 6.67 shares of Framewaves, Inc. restricted common stock for each issued and outstanding share of B6 Sigma, Inc. The acquisition has been accounted for as a “reverse purchase”merger” and, accordingly, the operations of Framewaves, Inc. prior to the date of acquisition have been eliminated. Unless otherwise indicated or the context otherwise requires, the term “B6 Sigma” refers to B6 Sigma, Inc., a Delaware corporation, which, until the short-form merger referenced below, was our wholly-owned, operating company acquired in September 2010; the terms the “Company,” “Sigma,” “we,” “us” and “our” refer to Sigma Labs, Inc., together with B6 Sigma, Inc. Prior to December 29, 2015, we conducted substantially all of our operations through B6 Sigma. On December 29, 2015, we completed a short-form merger of B6 Sigma into Sigma. As a result, B6 Sigma became part of Sigma and no longer exists as a subsidiary.

B6 Sigma, Inc., incorporated February 5, 2010, was founded by a group of scientists, engineers and businessmen to develop and commercialize novel and unique manufacturing and materials technologies. The Company believes that some of these technologies will fundamentally redefine conventional quality assurance and process control practices by embedding them into the manufacturing processes in real time, enabling process intervention and ultimately leading to closed loop process control. The Company anticipates that its core technologies will allow its clientele to combine advanced manufacturing quality assurance and process control protocols with novel materials to achieve breakthrough product potential in many industries including aerospace, defense, oil and gas, bio-medical, and power generation.

Basis of Presentation – The accompanying financial statements have been prepared by the Company in accordance with Article 8 of U.S. Securities and Exchange Commission Regulation S-X. In the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows at March 31,September 30, 2017 and 2016 and for the periods then ended have been made. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted. The Company suggests these condensed financial statements be read in conjunction with the December 31, 2016 audited financial statements and notes thereto included in the Company’s Form 10-K. The results of operations for the periods ended March 31,September 30, 2017 and 2016 are not necessarily indicative of the operating results for the full year.

Reclassification – Certain amounts in prior-period financial statements have been reclassified for comparative purposes to conform to presentation in the current-period financial statements.

Loss Per Share –The computation of loss per share is based on the weighted average number of shares outstanding during the period in accordance with ASC Topic No. 260, “Earnings Per Share.”

Recently Enacted Accounting Standards – The FASB established the Accounting Standards Codification (“Codification” or “ASC”) as the source of authoritative accounting principles recognized by the FASB to be applied by nongovernmental entities in the preparation of financial statements in accordance with generally accepted accounting principles in the United States (“GAAP”). Rules and interpretive releases of the Securities and Exchange Commission (“SEC”) issued under authority of federal securities laws are also sources of GAAP for SEC registrants.

Recent Accounting Standards Updates (“ASU”) through ASU No. 2015-01 contain technical corrections to existing guidance or affects guidance to specialized industries or situations. The Company has evaluated recently issued technical pronouncements and has determined that these updates have no current applicability to the Company or their effect on the financial statements would not have been significant.

Accounting Estimates - The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimated by management. Significant accounting estimates that may materially change in the near future are impairment of long-lived assets, values of stock compensation awards and stock equivalents granted as offering costs, and allowance for bad debts and inventory obsolescence.

Overview

Sigma Labs, Inc. (the “Company,” “we,” “us,” or “Sigma”) is a software company that has developed quality assuranceIn-Process-Quality-Assurance (“IPQA”) software known as PrintRite3D®, which. This technology is also sometimes referred to as Real-Time-Computer-Aided Inspection (“CAI”).  Sigma believes that its PrintRite3D® solves some of the major problemsproblem that havehas prevented large-scale metal part production using 3D printers...real-time computer-aidedprinters.

3D metal manufacturing is a technology that uses lasers to form or create parts out of welding powdered metals into a 3-dimensional (3D) object. The quality of these parts can vary from any given part to another on a single production run. Therefore, traditional after the fact quality inspection (“CAI”). methods do not assure quality of 3D printed parts. Sigma believes that the best, indeed, only way to attain high yields for both manufacturing quality and cost efficiency is an IPQA® approach that looks at each part in real time as it is being manufactured and determines in real time whether it meets quality specifications.

GE Aviation for example, has stated that it plans to commit $3.5 billion by 2020 to, among other things, build a metal 3D production facility for its Leap engine and other engines to produce the applicableLeap engine 3D printed metal parts. Since September 2016, GE has spent over $1 billion buying controlling interests in AM equipment manufacturers, Concept Laser and Arcam AB, and invested over $300 million creating AM manufacturing capability in both the United States and India. However, withoutunless companies that utilize a 3D production facility like GE Aviation effectively beingare able to effectively check each part for conforming attributes of shape, density, strength and consistency in real-time during the manufacturing process, we believe that such companies will not be ableat risk of letting some substandard parts through and, also, be unable to adequately addressimprove the major problems currently preventing large-scaleworkflow and high-quality yields of 3D printing functional metal 3D production.parts. We believe that our software, which iscan be positioned “inside” the 3D metal printer, solves these problems by assuring each part is being made to the quality specifications of the computer fileas itsuch part is being made. We enablemade. In essence, our software enables 3D prototyping to become 3D manufacturing. Instead of performing quality assurance (“QA”) post production or after the fact, our PrintRite3D® software couldhas been designed to fundamentally redefine conventionaltraditional QA by embedding quality assurance and process control into the manufacturing process in real time.

We have filed patent applications directed toon our In-Process Quality Assurance™ (“IPQA®”) process and procedure for advanced manufacturing. In addition, we anticipate that our core PrintRite3D® software will enable our customers to combine their advanceddigital manufacturing technologies with our 3D manufacturing QA to achieve both cost savings and strongermore reliable parts. Vertical markets that we believe would benefit from our technology and software include aerospace, defense, bio-medical, power generation, and oil & gas industries. We provide our software products to customers in the form of Software as a Service (“SaaS”).

About 3D Printing

3D printing (“3DP”) or additive manufacturing (“AM”) is changing the world by going directly from computer graphics to realactual parts. 3D printing has been applied to the manufacture of plastic parts for several years.decades. 3D manufacturing of metal parts involves directing a laser or other energy source at a layer of powdered metal and melting it. These layers become melted together from the bottom up. RevenuesWorldwide revenues attributable to 3D manufacturing for metal products were $88.1 million in 2015 (Wohlers Report 2016, 3D Printing and Additive Manufacturing State of the Industry – Annual Worldwide Progress Report).

The application of 3D printing to high-tolerance, precision manufactured metal parts has only recently emerged. 3D printing of metal parts today represents only a minor percentage of all 3D manufacturing. However, we believe the greatest future growth for 3D printing appears to be in metal parts, given the interest and investment being made by Fortune 100 companies, Federal government laboratories and agencies as well as university-based institutions. Emphasis from these high-end manufacturers and technology leaders is strongly focused on qualityhelping the transformation of analog manufacturing of precision, high-tolerance parts in the U.S. today to a digital enterprise of tomorrow complete with automation, robotics and precision manufacturing for high-tolerance parts.closed-loop process control. We believe that the on-going success of 3D printing for metal parts will be highly dependent upon the evolution of digital quality assurance procedureprocedures used, such as our PrintRite3D® methodology.process control.

About Quality Assurance in 3D Printing

Current methods for providing quality in 3DP are generally either inaccurate due to use of procedures that do not recognize and measure the primary quality issues of 3D metal manufacturing or are cost prohibitive because approximately 25%due to the expense of equipment required to examine the interior of complex dense parts produced bysuch as 3D printing needcan create, and further, may be inaccurate due to be destroyed in the post-production quality control process. Additionalmisuse of statistically based assessments.  After 3D-manufacture, costs are normally incurred by using non-destructive technologies such as ultrasound and non-traditional x-ray scanning technology on these parts, and old-fashioned visual inspection. Destructive testing of 3D parts is a mis-applied carryover from current Subtractive Manufacturing quality assurance practice in which the great consistency of CNC machines  permits quality inspectors to infer the quality of a production run by cutting up and analyzing a statistically relevant number of parts. The test result of the parts that are destroyed and analyzed have been, at great time and expense, statistically demonstrated to be representative of the rest of the parts in the production lot. The underlying premise of quality assurance for Subtractive Manufactured parts is that if a machine is set up properly, then all parts it produces will be the same. This simple, effective and accurate quality system does not apply to Additive Manufacturing, in which each part is built in an average production lot of 5-20, and in which quality variance may occur from part to part and within any part notwithstanding that the AM machine settings are the same. Therefore, unable to rely on a traditional statistically based quality system, 3D Manufacturing’s optimum quality assurance system would evaluate the quality of each individual part.  PrintRite3D®’s in-process quality inspection approach of each part individually allows a manufacturer to use AM to form a single part, such as a hip replacement or one spare aircraft part needed on an aircraft carrier, or several lots of the same part, in large quality – each approved or rejected in real time and based upon 100% inspection during fabrication. We offer our clientscustomers’ the ability to use real-time sensors to track individual scans of each layer, and our software continuously analyzes the part health so that when it is finished we knowcan determine if it ismeets the production quality.quality standard set by the customer. We believe our PrintRite3D® software could reduce inspection costs by a factor of 10 and development time for new parts by 50% or more. Most importantly is the ability of our software to reduce risk associated with the qualification and certification of printed parts.

By using PrintRite3D® software, a high-precision manufacturer would have the ability to offer its customers on an exclusive basis, product guaranteeswarranties and assurances that its product wasprinted parts were produced in compliance with stringent quality requirements. Initial ordersOrders for our software have been received from GE Aviation, Honeywell Aerospace, AerojectAerojet Rocketdyne, Woodward, Siemens Turbomachinery, Pratt and Whitney, and Solar Turbines.

We believe there is potential for our PrintRite3D® software to be incorporated into a majority of 3D metal printing devices made by companies like Electro-Optical Systems (“EOS”), Additive Industries, Concept Lasers, Trumpf Lasers, Renishaw, Sentrol, Farsoon, Desktop Metal and others.

Sigma’s Cloud-Based IIoT Solutions

The process of making a 3D printed part could start with our customers loading a computer aided design (“CAD”) model of the part into the Cloud as shown in “A” in Figure 1. Next, computer aided engineering (“CAE”) and/or computer aided manufacturing (“CAM”) instructions are sent to the 3D printer (see “B”, as shown in Figure 1). Metal powder in the machine is then deposited onto the build platform where a laser beam, or other energy source, focused onto the build platform melts each successive layer of powder in 20-5020-60 micron increments. Our CAI sensorsPrintRite3D SENSORPAK® (see “C” in Figure 1) detect, record, analyzedetects, records, analyzes and comparecompares the part as it is being made layer-by-layer against the CAD/CAM specifications and physical reference points for quality assurance during the manufacturing. Our PrintRite3D INSPECT®, Version 3.0 software certifies the shape, strength, and internal densitydetermines compliance of each part which eliminatesfor its metallurgical quality. Our alpha version of PrintRite3D CONTOUR® software determines the need to: (1) destroyshape and conformity of a large percentage of the parts during process validation andpart in post-production quality assurance; and (2) retain all of the metal as opposed to cutting pieces and wasting metal.real-time manufacture with its geometric design specification.

Our PrintRite3D®PrintRite3D® CAI web-based software suite (see “D” in Figure 1) is being designed to resideresides in situ and/or in the Cloud (see “A” in Figure 1) of the Industrial Internet of Things (“IIoT”). We enable manufacturing engineers to assure the part quality layer-by-layer, provide for manufacturing statistical process control and harvest, aggregate, and analyze Big Data from the manufacturing real-time data collected from our PrintRite3D® SENSORPAK™PrintRite3D SENSORPAK® (see “C” in Figure 1), as well as post-process manufacturing data collected by our customers (see “E” in Figure 1).

Our specialized sensor suite (see “C” in Figure 1), known as PrintRite3D® SENSORPAK™PrintRite3D SENSORPAK®, is an IIoT-enablededge computing device. It contains the modular hardware and software necessary to connect to “cyber-physical” objects (see “B” in Figure 1) living on the manufacturing floor. It allows for bi-directional information flow between the manufacturing floor and the Cloud (see “A” in Figure 1). It starts a million-fold data reduction that finishes with our PrintRite3D® CAI software,Digital Quality Record (“DQR”) and report, which provides customers with product guarantees and assurances that parts were produced in compliance with stringent quality standards. It can collect, analyze, aggregate, filter, and then further communicate data from the manufacturing floor to the Cloud (see “A” in Figure 1) and enable links to other areas (see “F” in Figure 1) of the IIoT.

Other markets such as firearms and recreational equipment.

We generate revenues through PrintRite3D® hardware and sensor sales and CAI software licensing of our PrintRite3D® technology to customers that seek to improve their manufacturing production processes, and through ongoing annual software upgrades and maintenance fees. Additionally, we generate revenues from our contract manufacturing activities in metal AM. By running a contract AM services operation, we are able to understand the current needs of our customers and where they are going with their next-generation product development efforts. Contract AM further allows us a means for continuing/self-funding our IPQA®-enabled R&D and product development activities for PrintRite3D® CAI software. We provide our AM contract manufacturing services to customers in the form of Quality as a Service (“QaaS”). Starting with our PrintRite3D® cloud-based SaaS model, customers will contract with us for CAE, CAM and CAI services to generate and establish a digital quality record (“DQR”)DQR for AM built parts. Each DQR is cloud-based and allows for archiving and storage of quality data, access to our big data ANALYTICS™ software App for continuous quality monitoring and improvement, and automatic industry benchmarking while maintaining firewalls between company-specific data.

In late 2015, we launched two programs − an Early Adopter Program (“EAP”(“EAP”) and an Original Equipment Manufacturer (“OEM”(“OEM”) Partner Program − designed to broaden our market presence and speed adoption of our PrintRite3D® technology. The EAP was designed to attract end user customers who have an existing, installed base of 3D metal printers and to offer them incentivized pricing in return for feedback on initialengineering and beta releases of our PrintRite3D® software Apps. Our OEM Partner Program was specifically designed for AM machine manufacturers seeking to embed our PrintRite3D® quality assurance software Apps directly into their machines for customers purchasing a turnkey solution for their new AM machine purchases.

We possess the resident expertise to provide manufacturing materials and process (“M&P”) engineering services and support to companies using our PrintRite3D® software Apps for metal AM. Accordingly, in addition to our primary business focus, we intend to generate revenues by providing such manufacturing engineering services and support to businesses licensing our PrintRite3D® software Apps.

Additionally, ourOur President and Chief ExecutiveTechnology Officer has worked at or with the Edison Welding Institute, the United States Department of Energy (“DOE”) national laboratories (including the Knolls Atomic Power Laboratory, Bettis Atomic Power Laboratory, Los Alamos National Laboratory and Sandia National Laboratory) over the last 32past 34 years. Due to his work with the DOE, our President and Chief ExecutiveTechnology Officer has developed extensive relationships with the DOE and its network of national laboratories. Accordingly, we expect to leverage these relationships in connection with licensing and developing technologies created at such national laboratories for commercialization in the private sector.

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts in the accompanying consolidated financial statements and related notes. These estimates and assumptions have a significant impact on our consolidated financial statements. Actual results could differ materially from those estimates. Critical accounting policies are those that require the most subjective and complex judgments, often employing the use of estimates about the effect of matters that are inherently uncertain. Our significant accounting policies are disclosed in Note 1 to the Consolidated Financial Statements included in our Annualthis Quarterly Report Dated December 31, 2016.on Form 10-Q. However, we do not believe that there are any alternative methods of accounting for our operations that would have a material effect on our financial statements.

Results of Operations

We expect to generate revenue primarily by selling and licensing our manufacturing and materials technologies to businesses that seek to improve their manufacturing production processes and/or manipulate and improve the most functional characteristics of the materials and other input components used in their business operations. We also expect to generate revenues though contract AM manufacturing using our in-house metal 3D printing capability. However, we presently make limited sales of these technologies and services, which include limited sales of non-exclusive licenses to use our PrintRite3D® technologies, including under our recently established Early Adopter Program and OEM Partner Program, as described above. Our ability to generate revenues in the future will depend on our ability to further commercialize and increase market presence of our PrintRite3D® technologies.

During the three and nine months ended March 31,September 30, 2017, we recognized revenue of $150,203,$78,046 and $518,802, respectively, as compared to $358,455$189,952 and $642,230 in revenue recognized during the same periodperiods in 2016. The decrease in revenue was primarily due to reduced programmatic sales, the completion ofrevenue from which was only partially replaced by new EAP and OEM Partner Program sales due to the GEA America Makes Program in 2016, providing three months of revenue in 2016 but no revenue in 2017, and the completion of the DARPA Phase II project in 2016, providing three months of revenue in 2016 but no revenue in 2017.incentivized pricing associated with those two programs. We generated revenues and financed our operations during the three and nine months ended March 31,September 30, 2017 and 2016 primarily from PrintRite3D® system sales, as wellDARPA and Aerojet programs, engineering consulting services we provided to third parties during these periods and through sales of our common stock and debt securities. We expectanticipate that our revenue will increase in future periods as we seek to further commercialize and expand our market presence for our PrintRite3D®-related technologies, and obtain new contract manufacturing orders in connection with our EOS M290 metal printer, as well as further perform on our engineering consulting contracts for the Aerojet Rocketdyne USAF Booster Propulsion program and Honeywell Aerospace for the DARPA Period 3.Phase III and Plus up efforts. Our costCost of service revenueRevenue for the three and nine months ended March 31,September 30, 2017 was $74,534$81,214 and $267,160, respectively, as compared to $107,582$69,259 and $207,744 for the same periodperiods in 2016. The increases are attributable to the additional costs associated with implementation of the EAP and OEM programs.

Our generalGeneral and administrative expensesAdministrative Expenses for the three and nine months ended March 31,September 30, 2017, were $643,795,$576,855 and $1,814,843, respectively, as compared to $395,488$437,870 and $1,314,055 for the same periodperiods in 2016. Our payroll expenses for the three and nine months ended March 31,September 30, 2017 were $290,188,$295,890 and $973,172, respectively, as compared to $215,589$259,011 and $727,494 for the same periodperiods in 2016. Our expenses relating to stock-based compensation for the three and nine months ended March 31,September 30, 2017 were $139,632$199,225 and $505,630, respectively, as compared to $77,551$105,641 and $236,554, respectively, for the same periodperiods in 2016. Our research and development expenses for the three and nine months ended March 31,September 30, 2017 were $135,195$57,947 and $225,562, respectively, as compared to $39,071$37,526 and $88,504 for the same periodperiods in 2016.

General and administrative expensesAdministrative Expenses principally include internal operating and sales expenses and outside service fees, the largest component of which consists of services in connection with our obligations as an SEC reporting company, in addition to other legal, accounting, marketing and investor relations fees.company. The net increase in generalGeneral and administrative expensesAdministrative Expenses for the three and nine months ended March 31,September 30, 2017 as compared to the same period in 2016 is principally the result of increased fees relating to and as a consequence of our February 2017 public offering that resulted in net proceeds of approximately $5,250,000,$5,225,650, fees incurred in connection with investing in strategic partners, the increase in interest and finance costs on the $1,000,000 note originated in October of 2016, along with ourthe continued development of our IPQA®-enabled PrintRite3D® technologies and our related efforts to expand our services. The net increase in payroll expenses for the three and nine months ended March 31,September 30, 2017 as compared to the same periodperiods in 2016 is principally the result of our hiring of additional software development staff to assist in acceleration of our IPQA®-enabled PrintRite3D® technologies since March 2016.and 2017 increases in administrative salaries. The net increase in research and development expenses for the three and nine months ended March 31,September 30, 2017 as compared to the same periodperiods in 2016 is principally the result of increased contract consulting combined with software and hardware upgrades required for the continued development and improvementsimprovement of our software and technology. The net increase in stock-based compensation costs is due to the fact that the majority of stock options were granted after March 31,September 30, 2016, thus more stock option vesting occurred in the firsteach quarter of 2017 than in the same period inperiods of 2016.

As a result of our increased operating activities, includingOur General and Administrative expenses are expected to continue to increase as we seek further commercialization of our IPQA®-enabled PrintRite3D® technologies and ourthrough increased marketing and sales efforts associated with such technologies, including with respect to our EAP and OEM Partner Program, and our contract manufacturing activities, our general and administrative expenses in the future are expected to continue to increase.efforts. Similarly, we anticipate that our payroll and non-cash compensation expenses will continue to increase as we engage more employees and other service providers to support our efforts to grow our business.

Our net loss for the three and nine months ended March 31,September 30, 2017 increased over each of the prior year comparative periods and totaled $943,965$1,116,910 and $3,049,616, respectively, as compared to $470,667$719,320 and $1,931,833 for the same periodperiods in 2016. OurThis increase in net loss was attributable to a decrease in revenue decreased and we experienced a larger netan increase in expenses as noted above.

Liquidity and Capital Resources

As of March 31,September 30, 2017, we had $4,633,046$2,691,487 in cash and had a working capital surplus of $4,133,817,$2,482,056, as compared with $398,391 in cash and a working capital surplus of $110,799 as of MarchDecember 31, 2016.

On February 21, 2017, the Company closed an underwritten public offering of equity securities resulting in net proceeds of approximately $5,250,000,$5,225,650, after deducting underwriting discounts and commissions and other offering expenses payable by the Company.

We expect to generate revenue primarily by licensing our manufacturing and materials technologies to businesses that seek to improve their manufacturing production processes and/or manipulate and improve the most functional characteristics of the materials and other input components used in their business operations. We also expect to generate revenues by providing contract AM services using our EOS M290 metal AM system. However, for the period from our inception through March 31,September 30, 2017, we generated revenue and financed our operations primarily from PrintRite3D®-enabled engineering consulting services as well as thru the programmatic work performed on both the DARPA Phase II and Aerojet programs we provided during this period and through private sales of Sigma common stock and debt securities. During the remainder of 2017, weWe expect to further ramp up our operations and our commercialization and marketing efforts, which we anticipate will increase the amount of cash we will use in our operations.

We expect that our continued development of our IPQA®-enabled PrintRite3D® technology will enable us to further commercialize this technology for the AM metal market in the remainder of 2017. However, until commercialization of our full suite of PrintRite3D® technologies, we plan to continue funding our development activities and operating expenses by licensing our PrintRite3D® systems and conducting supporting field services, as applicable, and providing PrintRite3D®-enabled engineering consulting services concerning our areas of expertise (materials and manufacturing quality assurance and process control technologies) and contract manufacturing for metal AM, and through the use of proceeds from sales of our securities.

Cash used in operating activities increased a net of $479,203 during the threenine months ended March 31,September 30, 2017, increased to $440,553$1,801,569 from $393,028$1,322,366 during the same period in 2016,2016.  This increase was primarily due to the increases in general and administrative, payroll and research and development expenses as noted above which were partially offset by the net effect of changes in accounts receivable, notes payable, accrued expenses and accounts receivable during the quarters. Also, there was a larger net loss during the three months ended March 31, 2017 offset by more non-cashaccrued expenses during the quarter, as compared to the same period in 2016.

Some of our engineering consulting contracts, including the contracts from Honeywell Aerospace, Bendix King, Siemens, EOS, Solar Turbines, Pratt & Whitney and Aerojet Rocketdyne, are fixed-price contracts, for which we will be entitled to receive a specified fee regardless of our cost to perform under such contract. In connection with entering into these fixed-contract consulting arrangements, we are required to estimate our costs of performance. To actually earn a profit on these contracts, we must accurately estimate costs involved and assess the probability of meeting the specified objectives, realizing the expected units of work or completing individual transactions, within the contracted time period. Accordingly, if we under-estimate the cost to complete a contract, we remain obligated to complete the work based on our initial cost estimate, which would reduce the amount of profit actually earned under the contract.

We do not have any material commitments for capital expenditures during the next twelve months. Pursuant to the September 29, 2017 amendments to the Notes and Warrants discussed in Note 4 to our financial statements above, Sigma paid an aggregate amount equal to $500,000 plus all accrued interest on the Notes on October 2, 2017. In consideration of the foregoing, the Investors agreed to, among other things, extend the payment date of the remaining 50% of the outstanding principal balance of the Notes from October 17, 2017 to the earlier of May 18, 2018 or the closing of the Company’s next underwritten public offering of securities in which the Company raises gross proceeds of at least $3,000,000 (should the Company elect to commence and close such an offering of securities).

Based on the funds we have as of May 15,November 14, 2017, and the proceeds we expect to receive under our PrintRite3D®-enabled engineering consulting agreements, from selling or licensing our PrintRite3D® systems and software, and sales of contract AM manufacturing for metal AM parts, and from sales of our securities, we believe that we will have sufficient funds to pay our administrative and other operating expenses through 2017. Until we are able to generate significant revenues and royalties from selling or licensing our PrintRite3D®-enabled technologies and our contact AM manufacturing services, our ability to continue to fund our liquidity and working capital needs will be dependent upon revenues from existing and future PrintRite3D®-enabled engineering consulting contracts, strategic partnerships, contract manufacturing orders in connection with our EOS M290 metal printer, and proceeds received from sales of our securities. Revenue we generate from licensing our technologies is not expected to increase significantly during 2017 andwe also anticipate that there will be an increase in the amount of cash we will use during the remainder of 2017 in connection with our efforts to identify compatible businesses to possibly acquire that will be synergistic with our business (although there is no assurance than any acquisition will be consummated). Accordingly, we will have to obtain additional capital from the sale of additional securities or by borrowing funds from lenders to fulfill our business plans. If we issue additional equity or debt securities, stockholders may experience additional dilution or the new equity securities may have rights, preferences or privileges senior to those of existing holders of our common stock. There is no assurance that we will be successful in obtaining additional financing. Such financing, if in the form of equity, may be highly dilutive to our existing stockholders and may otherwise include onerous terms. Such financing, if in the form of debt, may include debt covenants and repayment obligations that are onerous and that adversely affect our business operations. If adequate funds are not available to us, we may be required to delay, limit or terminate our business operations If we fail to obtain sufficient funding when needed, we may be forced to delay, scale back or eliminate all or a portion of our commercialization efforts and operations.

Inflation and changing prices have had no effect on our continuing operations over our two most recent fiscal years.

We have no off-balance sheet arrangements as defined in Item 303(a) of Regulation S-K.

Rule 13a-15(e) under the Exchange Act defines the term “disclosure controls and procedures” as those controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms and that such information is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Based upon an evaluation of the effectiveness of our disclosure controls and procedures performed by our management, with the participation of our President and Chief Executive Officer, and Principal Financial and Accounting Officer, as of the end of the period covered by this annualquarterly report, our management concluded that our disclosure controls and procedures are effective at a reasonable assurance level in ensuring that information required to be disclosed by us in our reports is recorded, processed, summarized and reported within the required time periods. In addition, no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) occurred during the quarter ended March 31,September 30, 2017 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
