NOTE 1 - Summary of Significant Accounting Policies

Nature of Business -Sigma Labs, Inc., formerly named Framewaves, Inc., a Nevada corporation, was founded by a group of scientists, engineers and businessmen to develop and commercialize novel and unique manufacturing and materials technologies. Sigma 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. The terms the “Company,” “Sigma,” “we,” “us” and “our” refer to Sigma Labs, Inc.

Basis of Presentation - The accompanying financial statements have been prepared by the Company in accordance with Generally Accepted Accounting Principles (“GAAP”) in the United States of America and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim reporting.America. 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 June 30, 20182019 and 20172018 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, 20172018 audited financial statements and notes thereto included in the Company’s Form 10-K. The results of operations for the periods ended June 30, 20182019 and 20172018 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. In addition, $153,013 of issuance costs associated with the February 2017 capital raise have been reclassified from operating costs to a reduction in additional paid in capital.

Continuing Operations - The Company has sustained losses and had negative cash flows from operating activities since its inception. In 2017 and the first six months of 2018, management has reported a change of strategy under which the company ceased to make sales and installations for research and development applications in order to focus its efforts entirely on potential customers already manufacturing 3D metal parts and therefore, already in need of quality improvement. The result of this change between September 2017 and the second quarter of 2018 was a significant decrease in revenues which the Company hopes to replace with orders for serial production use. The Company has raised significant equity capital as it continues to develop new products with commercial applications that may increase future revenues. On February 21, 2017, the Company closed an underwritten public offering of equity securities resulting in net proceeds of approximately $5,097,000, after deducting underwriting discounts and commissions and other offering expenses payable by the Company. The Company was able to fund operations for 2017 with these funds and end the year with a cash balance of $1,515,674. On March 28, 2018, Sigma received $535,000 in full payment of the Morf 3D note and related accrued interest balance. In addition, on April 6, 2018, the Company closed a private placement offering of equity securities resulting in net proceeds of approximately $877,500, after deducting commissions and other offering expenses payable by the Company. On June 26, 2018 the Company closed a public offering of equity securities resulting in net proceeds of approximately $2,068,900, after deducting placement agent commissions and other offering expenses payable by the Company. As a result, the Company currently has sufficient cash and working capital to fund operations through the first quarter of 2019 and is anticipating that sales contracts may be closed in the second half of fiscal 2018 generating additional cash flow in the near term.

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 ASCAccounting Standards Codification (“ASC”) Topic No. 260, “Earnings Per Share.” Shares underlying the CompaniesCompany’s outstanding warrants, options or note conversion features were excluded due to the anti-dilutive effect they would have on the computation. At June 30, 2019 the Company had 3,620,610 warrants, 1,108,192 stock options and a $50,000 Convertible Note Payable outstanding. The total number of shares of common stock underlying these instruments is 4,753,802. At June 30, 2018 the Company had 350 convertible preferred stock shares, 3,477,0603,228,500 warrants, 664,707 stock options and a $50,000 Convertible Note Payable outstanding. The total number of shares of common stock underlying these instruments is 4,516,767. At June 30, 2017 the Company had 1,701,500 warrants, 229,938 stock options and $1,000,000 in Convertible Notes Payable outstanding. The total number of shares of common stock underlying these instruments was 2,431,438.4,268,207.

The following data shows the amounts used in computing loss per share and the effect on income and the weighted average number of shares of dilutive potential common stock for the periods ended June 30, 20182019 and 2017:2018:

Recently Enacted Accounting Standards - The FASB established the Accounting Standards Codification (“Codification” or “ASC”)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”).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”) throughIn February 2016, the FASB issued ASU No. 2018-11 contain technical corrections2016-02, “Leases” which was issued to existing guidance or affects guidance to specialized industries or situations.increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The amendments in ASU 2016-02 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company has evaluated recently issued technical pronouncementsthis standard and has determined that other than ASU 2014-09 (Topic 606), addressed below, these updates have no current applicability to the Company or their effect on the financial statements wouldit will not have been significant.

In May 2014, the FASB issued ASU 2014-09 (Topic 606) “Revenue from Contracts with Customers.” Topic 606 supersedes the revenue recognition requirements in Topic 605, “Revenue Recognition” (Topic 605), and requires entities to recognize revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. On January 1, 2018, we adopted Topic 606 and all related amendments (“new revenue standard”) to those contracts which were not completed as of January 1, 2018 using the modified retrospective method. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. There is nocurrently require any adjustment to the opening balance of retained earnings due to the cumulative effect of initially applying the new revenue standard determined to be immaterial. We expect the impact of the adoption of the new revenue standard to be immaterial to our net income on an ongoing basis.Sigma’s financial reporting.

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.

20182019 Developments

In the second quarter of 2018,2019, we reported several events, including the following (in reverse chronological order):

On June 26, 2018August 13, 2019, we announced that we have been selected by a major international OEM machine manufacturer to install our proprietary PrintRite3D® products. As part of the Companyagreement, the OEM will complete our Rapid Test and Evaluation program and will install the PrintRite3D® in two different countries for analysis and proof-of-performance purposes.

On August 2, 2019, we closed a public offering of equity securities in which we issued 2,875,000 shares of its common and preferred stock and warrants to purchase common stock resulting in net proceeds of approximately $2,068,900.$1,971,000, after deducting placement agent commissions and other offering expenses payable by us.

On July 30, 2019, we announced that we will work with Airbus to complete a Test and Evaluation Program of our new PrintRite3D® version 5.0 hardware and software followed by a validation phase on a powderbed fusion printer.

On June 19, 2018, Sigma received notice18, 2019, we announced that its U.S. Patent No. 9999924 entitled “Method and Systemwe signed a non-binding Memorandum of Understanding with Materialise NV to cooperate in the integration of their MCP Controller with our PrintRite3D^® technology. Combining the sophisticated control technology with in-situ process monitoring for Monitoringmetal additive manufacturing will give customers maximal control on the production process, allowing them to become even more productive.

On May 14, 2019, we announced that we will launch Version 5.0 of our PrintRite3D^® platform at the RAPID+TCT 2019 Additive Manufacturing Processes” had been issued. The patent provides protection for methods of assuring part quality using real time data from multiple sensor types.

On May 21, 2018,March 15, 2019, we receivedclosed a letter from Nasdaq notifying the Companypublic offering of equity securities resulting in net proceeds of approximately $1,679,230, after deducting placement agent commissions and other offering expenses payable by us.

On February 26, 2019, we announced that we were named a member of the Manufacturing Technology Centre (“MTC”) located at Ansty Park, Coventry, UK. Being a member of the MTC enables us to share and provide expertise and solutions for a number of MTC’s projects and also network with MTC’s existing members, including some of the UK’s leading aerospace companies.

On February 12, 2019, we announced that we were named a member of the Additive Alliance of Fraunhofer IAPT, a leading network for additive manufacturing (“AM”). As the first US company to be granted a membership in the Alliance, Sigma became part of the global research consortium to advance the development and implementation of AM. The membership enables us to demonstrate our PrintRite3D^® technology to key players in the market of metal AM.

On February 5, 2019, we announced that the U.S. Patent and Trademark Office has issued a Notice of Allowance for U.S. Patent Application No. 15/276,452, “Optical Manufacturing Process Sensing and Status Indication System.” The patent application covers a system of sensors configured to measure optical emissions generated by a scanning heat source during an additive manufacturing (AM) process and to analyze the data collected.

On January 17, 2019, we announced we were awarded a Test and Evaluation Program contract with a leading global materials and service provider in AM. The program is designed to demonstrate the value of Sigma’s PrintRite3D^® product capabilities and performance and to validate and quantify the repeatability and variability of AM production processes. So far we have had delays, diversions, and logistical alterations typical of many newly launched programs, yet importantly, there have been no longernegative performance issues in compliancethe RTE test results. The prototype RTE installation was with Materialise in 2018 and culminated in the minimum stockholders’ equity requirement for continued listing on the Nasdaq Capital Market. Nasdaq Listing Rule 5550(b)(1) requires companies listed on the Nasdaq Capital Marketproject announced in June 2019 to maintain stockholders’ equity of at least $2,500,000. In this Quarterly Report, the Company reported stockholders’ equity of $4,127,814 as of June 30, 2018, which is above the minimum stockholders’ equity required for continued listing. Accordingly, asintegrate Sigma’s technology with Materialise’s MCP control system. As of the date of this Quarterly Report, of our two most advanced RTEs in process, one states an expectation to add a second PrintRite3D® installation, and the Company believes that it has regained compliance with Nasdaq Listing Rule 5550(b)(1).other expects to enter the phase two evaluation (multiple machines of differing OEM brands) over the next 60-120 days.

On May 14, 2018, we announced the inaugural hire of our European customer salesThe size and support team.

During April 23-26, 2018 the Company participated in The Rapid 2018 Conference in Fort Worth, Texas, at which the Company exhibited its PrintRite3D® In-Process Quality Assurance (IPQA®) software applications.

During April 8-12, 2018, the Company participated in The Additive Manufacturing Users Group (AMUG) Conference and Exhibition in St. Louis, Missouri. Mark Cola, our President and Chief Technology Officer, participated as a panel member in the In-Situ Monitoring Panel discussion, which focused on the time and cost associated with validationquality of the manufacturing process for aerospace quality components.

On April 6, 2018,demanding high technology ‘brand name’ companies currently participating in, along with those teed-up to enter the Company closed a private placementRTE program, appears to confirm that the program is Sigma’s most auspicious highway to success and material revenue driving into 2020 and beyond. The Airbus RTE announcement on July 30, 2019 followed by our OEM double-RTE announcement on August 13, 2019 demonstrates that the market’s uptake of preferred stock and warrants resulting in net proceeds of approximately $877,500, after deducting commissions and other offering expenses payable by the Company. All shares of preferred stock that were issued in the offering were converted into an aggregate of 1,000,000 shares of common stock during the second quarter of 2018.this program initiative is accelerating.

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 Financial Statements included in this Quarterly Report 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

Three Months Ended June 30, 2019 and June 30, 2018

We expect to generate revenue primarily by selling and licensing our IPQA technologies, selling technical support services, and contract manufacturing and selling specialty parts and studies to businesses that seek to improve their manufacturing production processes and production-run quality yields. Our ability to generate revenues in the future will depend on our ability to further commercialize and increase market presence of our PrintRite3D® technologies, and it will depend on ifwhether key prospective customers continue to move from AM metal prototyping to production.

Three Months Ended June 30, 2018 and 2017

In the second quarter of 2018, we recognized revenue of $98,663 compared to $290,553 during the same period of 2017. The primary contributors to the $191,890 reduction were revenue decreases of $118,737 from the DARPA and Aerojet government programs and $128,174 from new system sales. These decreases were partially offset by an increase in net other revenue in the second quarter of 2018, principally attributable to $49,031 in revenue from contract AM service sales in the second quarter of 2018 compared to no such sales in the second quarter of 2017. Our cost of revenue for the second quarter of 2018 was $68,568 as compared to $111,412 during the same period of 2017. The decrease of $42,844 is primarily due to $43,915 of system costs associated with the second quarter 2017 system sales.

Sigma’s total operating expenses for the second quarter of 2018 were $1,422,511 compared to $1,108,234 for the same period of 2017, a $314,277 increase. Our operating expenses are comprised of internal operating and sales expenses, outside service fees, research & development costs, and depreciation & amortization.

The most significant of our operating expenses is personnel costs, comprised of payroll and stock-based compensation expense. Payroll costs in the second quarter of 2018 were $426,049 compared to $346,994 for the same period in 2017. The $79,055 increase result primarily from the strategic addition of six employees since the end of the second quarter of 2017, three in the third quarter of 2017 realignment and three in the second quarter of 2018 as we continue the concentrated acceleration of technology development and expand into the European 3D manufacturing market. Stock-based compensation for the second quarter of 2018 was $423,067 compared to $166,773 for the same period in 2017. The $256,294 increase resulted primarily from the issuance of stock options to our Chief Executive Officer in the second quarter of 2018, $61,651 of additional stock options vesting expense related to the options issued to our President and Chief Technology Officer under his amended and restated employment agreement, and the amortization of an additional $72,494 in Board of Director stock compensation cost in that same 2018 period.

During the three months ended June 30, 2019, we recognized revenue of $33,582, as compared to $98,663 in revenue recognized during the same period in 2018, Sigma incurred researcha reduction of $65,081. $10,000 of the reduction is directly attributable to the absence of any government program work in 2019, while the remaining 55,000 of it is attributable to the 100% dedication of our printer to Internal R&D in the second quarter of 2019 as we accelerated development of the Inspect product, as well as an overall decline in AM revenue.

Our Cost of Revenue for the three months ended June 30, 2019 and 2018 was $60,625 and $68,568, respectively, a reduction of $7,943. The decrease in our gross margin is primarily attributable to the additional travel and labor costs associated with the on-site and remote collaboration involved in initiation of the Company’s Rapid Test and Evaluation programs.

We have no credit lines as of August 13, 2018,14, 2019, nor have we ever had a credit line since our inception.

Based on the funds we have as of August 13, 2018,14, 2019, and the proceeds we expect to receive underfrom rapid test and evaluation engagements for our PrintRite3D®-enabled engineering consulting agreements, from selling or licensing ourupdated PrintRite3D® systemshardware and software andtechnology, sales of contract AM manufacturing for metal AM parts, possible sales of our securities and from the repayment of loans made by Sigma, we believe that we will have sufficient funds to pay our administrative and other operating expenses through at least the first quarter of 2019. Our ability to continue to fund our liquidity and working capital needs will be dependent upon the success of and revenues from existing and future PrintRite3D®-enabled engineering consulting-proof of concept contracts, follow-on contracts resulting from successful proof of concept engagements, possible strategic partnerships, contract manufacturing orders in connection with our EOS M290, and perhapspossibly by obtaining additional capital from the sale of additional securities or by borrowing funds from lenders to fulfill our business plans.

There is no assurance that we will be successful in obtaining additional funding. If we require and 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.
