Business Description and Basis of Presentation [Text Block]

Note 1 – Business Organization, Nature of Business and Basis of Presentation

Nature of Business

The Coretec Group Inc. (the “Group”) (formerly 3DIcon Corporation) (“3DIcon”) was incorporated on August 11, 1995, under the laws of the State of Oklahoma as First Keating Corporation. The articles of incorporation were amended August 1, 2003 to change the name to 3DIcon Corporation. During 2001, First Keating Corporation began to focus on the development of 360-degree holographic technology. From January 1, 2001, 3DIcon’s primary activity has been the raising of capital in order to pursue its goal of becoming a significant participant in the development, commercialization and marketing of next generation 3D display technologies.

Coretec Industries, LLC (“Coretec”), a wholly owned subsidiary of the Group (collectively the “Company”), was organized on June 2, 2015 in the state of North Dakota. Coretec is currently developing, testing, and providing new and/or improved technologies, products, and service solutions for energy-related industries including, but not limited to oil/gas, renewable energy, and distributed energy industries. Many of these technologies and products also have application for medical, electronic, photonic, display, and lighting markets among others. Early adoption of these technologies and products is anticipated in markets for energy storage (Li-ion batteries), renewable energy (BIPV), and electronics (Asset Monitoring).

Basis of Presentation

The accompanying condensed consolidated financial statements of the Company have been prepared without audit pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in the consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations. The Company believes that the disclosures made are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the Company’s year-end audited consolidated financial statements and related footnotes included in the previously filed Form 10-K, and in the opinion of management, reflects all adjustments necessary to present fairly the consolidated financial position of the Company. The consolidated results of operations for interim periods may not be indicative of the results which may be realized for the full year.

Note 2 – Summary of Significant Accounting Policies

Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Group and its wholly owned subsidiary, Coretec. Intercompany transactions and balances have been eliminated in consolidation.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and the disclosure of contingent assets and liabilities. Actual results could differ from the estimates and assumptions used.

Property and Equipment

Property and equipment is recorded at cost. Depreciation is recorded over the estimated useful lives using the straight-line method. Maintenance and repairs are expensed as incurred; major improvements and betterments are capitalized.

Intangibles

Intangible assets consist of patents and capitalized website costs. Intangible assets are recorded at cost (or fair value as of the date of acquisition in business combinations), and intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives.

Goodwill

The Company evaluates the carrying value of goodwill on an annual basis and between annual evaluations if events occur or circumstances change that would more likely than not reduce the fair value of goodwill below its carrying amount. When assessing whether goodwill is impaired, management considers first a qualitative approach to evaluate whether it is more likely than not the fair value of the goodwill is below its carrying amount; if so, management considers a quantitative approach by analyzing changes in performance and market-based metrics as compared to those used at the time of the initial acquisition. For the periods presented, no impairment charges were recognized.

Impairment of Long-Lived Assets

Long-lived assets, such as property and equipment and intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary.

Fair Value of Financial Instruments

The following methods and assumptions were used to estimate the fair value of each class of financial instrument held by the Company:

Current assets and current liabilities – The carrying value approximates fair value due to the short maturity of these items.

Notes payable – The fair value of the Company’s notes payable has been estimated by the Company based upon the liability’s characteristics, including interest rates, embedded instruments and conversion discounts. The carrying value approximates fair value.

Basic and Diluted Loss Per Common Share

Basic loss per common share is computed by dividing net loss by the weighted average number of vested common shares outstanding during the period. Diluted loss per share reflects the potential dilution that could occur if securities or other instruments to issue common stock were exercised or converted into common stock. The following securities are excluded from the calculation of weighted average dilutive common shares because their inclusion would have been anti-dilutive:

	September 30,
	2022		2021
Options		53,158,160		53,711,609
Warrants		142,814,000		142,604,000
Series A convertible preferred stock		115,000		115,000
Convertible debt		45,155,537		40,914,134
Total potentially dilutive shares		241,242,697		237,344,743

Research and Development

Research and development costs are expensed as incurred.

Subsequent Events

The Company evaluates events that have occurred after the balance sheet date but before the condensed consolidated financial statements are issued. Based upon the evaluation, the Company did not identify any recognized or non-recognized subsequent events that would have required adjustment or disclosure in the consolidated financial statements, except as disclosed in Note 6.

Income Taxes

The Company accounts for income taxes under an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company’s consolidated financial statements or tax returns. In estimating future tax consequences, the Company generally considers all expected future events other than enactments of changes in tax laws or rates. The effect on deferred tax assets and liabilities of a change in tax rates will be recognized as income or expense in the period that includes the enactment date. A valuation allowance is established when necessary to reduce deferred tax assets to the amount expected to be realized.

The Company’s tax benefits are fully offset by a valuation allowance due to the uncertainty that the deferred tax assets would be realized. Management considers the likelihood of changes by taxing authorities in its filed income tax returns and recognizes a liability for or discloses potential changes that management believes are more likely than not to occur upon examination by tax authorities. Management has not identified any uncertain tax positions in filed income tax returns that require recognition or disclosure in the accompanying consolidated financial statements.

Recent Accounting Pronouncements

The following is a summary of recent accounting pronouncement recently adopted by the Company:

In May 2021, the FASB issued ASU 2021-04, Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options which clarifies the accounting for a modification or an exchange of a freestanding equity-classified written call option that remains equity classified after a modification or exchange and the related EPS effects of such transaction if recognized as an adjustment to equity. The Company adopted ASU 2021-04 on January 1, 2022. The Company will consider this guidance for modifications or exchanges of freestanding equity-classified written call options.

10% Promissory note due January 2024, net

On October 4, 2019, the Company entered into a Credit Agreement and related Promissory Note with Diversified Alpha Fund of Navigator Global Fund Manager Platform SPC (“DAF”), the Lender. DAF is a segregated portfolio fund of Navigator Global Fund Manager Platform SPC. DAF is managed and controlled by Mollitium Investment Management (Mollitium). Mollitium utilizes Diversified Global Investment Advisors Ltd. (“DGIA”) to act in an advisory role. DGIA maintains an Investment Committee to support the services to Mollitium. Simon Calton serves as part of this five-member investment committee and in accordance with the investment committee’s guidelines, Mr. Calton does not participate in matters or voting that pertain to the Company due to his conflict of interest. Investment advice provided by DGIA to Mollitium are recommendations only and the final decision on actions are the responsibility of Mollitium. Carlton James Global Management, Ltd (CJGM) serves as a distributer of investments by introducing funds available to the market of which DAF is included in CJGM’s group of funds. Compensation to CJGM occurs when investments are made into funds that they introduce. CJGM is part of the Carlton James Group of which Mr. Calton is CEO.

The 10% Promissory Note, in a principal amount of $2,500,000, is due on the 15th day of the 4th anniversary of each advance with the first capital payment due on March 15, 2024. The Promissory Note has attached warrants to subscribe for and purchase 3,000,000 shares of common stock at an exercise price of $0.052 per share. Under the terms of the Credit Agreement, DAF will fund the Promissory Note in sixteen (16) tranches in amounts of $125,000 and $175,000 per month beginning in October 2019. The funding of the Promissory Note is at the discretion of DAF and may differ from the planned schedule. As of September 30, 2022, DAF has advanced $2,345,000 with no definitive date or commitment to advance the remaining $155,000. Interest is accrued monthly and paid in advance for the first 12 months and thereafter interest only payments shall be paid quarterly.

On November 16, 2021, the Company countersigned a letter of variation (the “Variation”) to the credit agreement entered into, on October 4, 2019, with DAF. Pursuant to the Variation, the Lender agreed to extend the repayment days for each advance made by Lender under the credit agreement until the fourth anniversary of such advance. DAF also communicated to the Company that interest only payments would be due on a quarterly basis, effective January of 2022.

Under the terms of the Promissory Note, DAF has the right to elect to convert all or part of the Promissory Notes at a price equal to seventy percent (70%) of the average closing price of the Company’s common stock as reported on the over-the-counter quotation system on the OTC Markets during the fifteen (15) calendar days prior to the loan closing date of October 4, 2019, which calculates to $0.0329 per share.

Under the terms of the Credit Agreement, warrants to subscribe for and purchase 3,000,000 shares of common stock at an exercise price of $0.052 per share were issued to DAF. The estimated value of the warrants granted monthly, with each advance, is calculated using the Black-Scholes option pricing model. The resulting estimated value of the warrant is used to proportionally allocate the fair value of the debt advance and the fair value of the warrants. As of September 30, 2022, 2,814,000 warrants have been granted under the terms of the DAF Credit Agreement. There were 210,000 warrants issued under the Credit Agreement during the nine months ended September 30, 2022. The allocated cost of the warrants amounted to $4,101 and $62,784 during the nine months ended September 30, 2022 and the year ended December 31, 2021. The allocated cost of the warrants is amortized over the life of the debt, with $34,346 and $35,358 amortized during the nine months ended September 30, 2022 and 2021, respectively.

Additionally, under the terms of the Credit Agreement, the Company agreed to pay a commitment fee of 3% of each advance and reimburse DAF for certain expenses in connection with the preparation, interpretation, performance and enforcement of the Credit Agreement. Those costs amounted to $5,250 and $10,350 for nine months ended September 30, 2022 and the year ended December 31, 2021. Those costs are being amortized over the life of the debt. The Company amortized $11,048 and $11,978 during the nine months ended September 30, 2022 and 2021, respectively.

Note 5 – Commitments and Contingencies

Warrants

Warrants to subscribe for and purchase up to 3,000,000 shares of common stock at an exercise price of $0.052 per share were included under the terms of the DAF Credit Agreement. The warrants will be issued in amounts of 150,000 and 210,000 per month during the funding period. In the event that funding advances deviate from the planned schedule then warrants will be issued pro-rata at 1.2 warrants for every $1 of funding. Warrants granted under the terms of the DAF Credit Agreement as of September 30, 2022 total 2,814,000. The estimated value of the warrants granted monthly, with each advance, is calculated using the Black-Scholes option pricing model. The expected dividend yield is based on the average annual dividend yield as of the grant date. Expected volatility is based on the historical volatility of our stock. The risk-free interest rate is based on the U.S. Treasury Constant Maturity rates as of the grant date. The expected life of the warrant is based on historical exercise behavior and expected future experience. The resulting estimated value of the warrant is used to proportionally allocate the fair value of the debt advance and the fair value of the warrants.

On March 2, 2021, the Company entered into a securities purchase agreement (the “Purchase Agreement”) with a single institutional investor in a private placement to sell (i) 23,500,000 shares of its common stock, (ii) pre-funded warrants to purchase up to an aggregate of 51,500,000 shares of its common stock, and (iii) warrants to purchase up to an aggregate of 82,500,000 shares of its common stock for gross proceeds of approximately $6,000,000. The combined purchase price for one share of common stock and associated Warrant is $0.08 and for one Pre-Funded Warrant and associated Warrant is $0.0799. The sale of the securities under the Purchase Agreement closed on March 5, 2021. The pre-funded warrants have an exercise price of $0.0001 per share, subject to adjustment as set forth in the pre-funded warrants for stock splits, stock dividends, recapitalizations and similar events. The pre-funded warrants will be exercisable immediately and may be exercised at any time until all of the pre-funded warrants are exercised in full. In addition, the Company agreed to issue to the placement agent (or its designees) warrants to purchase a number of shares equal to 8.0% of the aggregate number of shares and pre-funded warrant shares sold under the Purchase Agreement, or warrants to purchase an aggregate of up to 6,000,000 shares. The placement agent warrants generally will have the same terms as the warrants, except they will have an exercise price of $0.10.

Options

Stock options for employees, directors or consultants are valued at the date of award, which does not precede the approval date, and compensation cost is recognized in the period the options are vested. Stock options generally become exercisable on the date of grant and expire based on the terms of each grant.

The estimated fair value of options for common stock granted is determined using the Black-Scholes option pricing model. The expected dividend yield is based on the average annual dividend yield as of the grant date. Expected volatility is based on the historical volatility of our stock. The risk-free interest rate is based on the U.S. Treasury Constant Maturity rates as of the grant date. The expected life of the option is based on historical exercise behavior and expected future experience

On June 8, 2020, the Board of Directors consented to a share exchange agreement with holders of 21,500,000 options awarded on August 7, 2019. The agreement allows for holders to exchange their options for rule 144 common stock at an exchange rate of 0.6 shares per 1 option. The modification of these options did not result in any additional compensation because there was no change in the fair value. During the nine months ended September 30, 2022, 1,500,000 options were exchanged for 900,000 shares that were issued under the executed exchange agreement.

On March 23, 2022 the Company granted 950,000 options at an average grant date fair value of $0.055 determined using the Black-Scholes option pricing model. The options were granted to an employee and independent contractor for the Company.

Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2022

Accounting Policies [Abstract]

Consolidation, Policy [Policy Text Block]

Principles of ConsolidationThe condensed consolidated financial statements include the accounts of the Group and its wholly owned subsidiary, Coretec. Intercompany transactions and balances have been eliminated in consolidation.

Use of Estimates, Policy [Policy Text Block]

Use of EstimatesThe preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and the disclosure of contingent assets and liabilities. Actual results could differ from the estimates and assumptions used.

Property, Plant and Equipment, Policy [Policy Text Block]

Property and EquipmentProperty and equipment is recorded at cost. Depreciation is recorded over the estimated useful lives using the straight-line method. Maintenance and repairs are expensed as incurred; major improvements and betterments are capitalized.

Goodwill and Intangible Assets, Intangible Assets, Policy [Policy Text Block]

IntangiblesIntangible assets consist of patents and capitalized website costs. Intangible assets are recorded at cost (or fair value as of the date of acquisition in business combinations), and intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives.

Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]

Goodwill The Company evaluates the carrying value of goodwill on an annual basis and between annual evaluations if events occur or circumstances change that would more likely than not reduce the fair value of goodwill below its carrying amount. When assessing whether goodwill is impaired, management considers first a qualitative approach to evaluate whether it is more likely than not the fair value of the goodwill is below its carrying amount; if so, management considers a quantitative approach by analyzing changes in performance and market-based metrics as compared to those used at the time of the initial acquisition. For the periods presented, no impairment charges were recognized.

Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]

Impairment of Long-Lived Assets Long-lived assets, such as property and equipment and intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary.

Fair Value of Financial Instruments, Policy [Policy Text Block]

Fair Value of Financial InstrumentsThe following methods and assumptions were used to estimate the fair value of each class of financial instrument held by the Company:Current assets and current liabilities – The carrying value approximates fair value due to the short maturity of these items.Notes payable – The fair value of the Company’s notes payable has been estimated by the Company based upon the liability’s characteristics, including interest rates, embedded instruments and conversion discounts. The carrying value approximates fair value.

Earnings Per Share, Policy [Policy Text Block]

Basic and Diluted Loss Per Common ShareBasic loss per common share is computed by dividing net loss by the weighted average number of vested common shares outstanding during the period. Diluted loss per share reflects the potential dilution that could occur if securities or other instruments to issue common stock were exercised or converted into common stock. The following securities are excluded from the calculation of weighted average dilutive common shares because their inclusion would have been anti-dilutive:

	September 30,
	2022		2021
Options		53,158,160		53,711,609
Warrants		142,814,000		142,604,000
Series A convertible preferred stock		115,000		115,000
Convertible debt		45,155,537		40,914,134
Total potentially dilutive shares		241,242,697		237,344,743

Research and Development Expense, Policy [Policy Text Block]

Research and DevelopmentResearch and development costs are expensed as incurred.

Subsequent Events, Policy [Policy Text Block]

Subsequent EventsThe Company evaluates events that have occurred after the balance sheet date but before the condensed consolidated financial statements are issued. Based upon the evaluation, the Company did not identify any recognized or non-recognized subsequent events that would have required adjustment or disclosure in the consolidated financial statements, except as disclosed in Note 6.

Income Tax, Policy [Policy Text Block]

Income TaxesThe Company accounts for income taxes under an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company’s consolidated financial statements or tax returns. In estimating future tax consequences, the Company generally considers all expected future events other than enactments of changes in tax laws or rates. The effect on deferred tax assets and liabilities of a change in tax rates will be recognized as income or expense in the period that includes the enactment date. A valuation allowance is established when necessary to reduce deferred tax assets to the amount expected to be realized.The Company’s tax benefits are fully offset by a valuation allowance due to the uncertainty that the deferred tax assets would be realized. Management considers the likelihood of changes by taxing authorities in its filed income tax returns and recognizes a liability for or discloses potential changes that management believes are more likely than not to occur upon examination by tax authorities. Management has not identified any uncertain tax positions in filed income tax returns that require recognition or disclosure in the accompanying consolidated financial statements.

New Accounting Pronouncements, Policy [Policy Text Block]

Recent Accounting PronouncementsThe following is a summary of recent accounting pronouncement recently adopted by the Company:In May 2021, the FASB issued ASU 2021-04, Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options which clarifies the accounting for a modification or an exchange of a freestanding equity-classified written call option that remains equity classified after a modification or exchange and the related EPS effects of such transaction if recognized as an adjustment to equity. The Company adopted ASU 2021-04 on January 1, 2022. The Company will consider this guidance for modifications or exchanges of freestanding equity-classified written call options.
