GT BIOPHARMA, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

As of and For the Six Months Ended June 30, 2021 and 2020

Note 1 - Organization and Operations

In 1965, the corporate predecessor of GT Biopharma, Inc. (Company), Diagnostic Data, Inc. was incorporated in the State of California. Diagnostic Data changed its incorporation to the State of Delaware in 1972 and changed its name to DDI Pharmaceuticals, Inc. in 1985. In 1994, DDI Pharmaceuticals merged with International BioClinical, Inc. and Bioxytech S.A. and changed its name to OXIS International, Inc. In July 2017, the Company changed its name to GT Biopharma, Inc.

The Company is a clinical stage biopharmaceutical company focused on the development and commercialization of novel immuno-oncology products based off our proprietary Tri-specific Killer Engager (TriKE™), and Tetra-specific Killer Engager (Dual Targeting TriKEDual Targeting TriKE) platforms. The Company’s TriKE and Dual Targeting TriKE platforms generate proprietary therapeutics designed to harness and enhance the cancer killing abilities of a patient’s own natural killer cells, or NK cells.

Note 2 -Going Concern

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of business. As reflected in the accompanying consolidated financial statements, for the six months ended June 30, 2021, the Company incurred a net loss of $34.5 million and used cash in operating activities of $8.0 million. These factors raise substantial doubt about the Company’s ability to continue as a going concern within one year of the date that these financial statements are issued. The consolidated financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern. In addition, our independent registered public accounting firm, in their report on our audited financial statements for the year ended December 31, 2020, raised substantial doubt about the Company’s ability to continue as a going concern.

During the six months ended June 30, 2021, the Company received net cash of $24.7 million from the sale of 4,945,000 shares of its common stock pursuant to a public offering, issuance of notes payable for cash of $1.2 million and $16.3 million in cash from exercise of warrants for a total cash received of $42 million. At June 30, 2021, the Company had cash on hand in the amount of $39.5 million. The Company’s current operations have focused on business planning, raising capital, establishing an intellectual property portfolio, hiring, and conducting preclinical studies and clinical trials. The Company does not have any product candidates approved for sale and has not generated any revenue from product sales. The Company has sustained operating losses since inception and expects such losses to continue over the foreseeable future. Management is currently evaluating different strategies to obtain the required funding for future operations. These strategies may include but are not limited to: public offerings of equity and/or debt securities, payments from potential strategic research and development, and licensing and/or marketing arrangements with pharmaceutical companies. If the Company is unable to secure adequate additional funding, its business, operating results, financial condition and cash flows may be materially and adversely affected. Management estimates that the current funds on hand will be sufficient to continue operations through the next six months. The Company’s ability to continue as a going concern is dependent upon its ability to continue to implement its business plan.

Note 3 - Summary of Significant Accounting Policies

Basis of Presentation

The accompanying condensed consolidated financial statements are unaudited. These unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020 filed with the SEC on April 16, 2021 (the “2020 Annual Report”). The consolidated balance sheet as of December 31, 2020 included herein was derived from the audited consolidated financial statements as of that date.

8

In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments necessary to fairly present the Company’s financial position and results of operations for the interim periods reflected. Except as noted, all adjustments contained herein are of a normal recurring nature. Results of operations for the fiscal periods presented herein are not necessarily indicative of fiscal year-end results.

Basis of Presentation and Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, Oxis Biotech, Inc. and Georgetown Translational Pharmaceuticals, Inc. Intercompany transactions and balances have been eliminated in consolidation.

Reverse Stock Split

On February 10, 2021, the Company completed a 1:17 reverse stock split of the Company's issued and outstanding shares of common stock and all fractional shares were rounded up. All share and per share amounts in the accompanying financial statements have been adjusted retroactively to reflect the reverse stock split as if it had occurred at the beginning of the earliest period presented.

COVID-19

In March 2020, the World Health Organization declared coronavirus COVID-19 a global pandemic. This contagious disease outbreak, which has continued to spread, has adversely affected workforces, customers, economies, and financial markets globally. It has also disrupted the normal operations of many businesses. This outbreak could decrease spending, adversely affect demand for the Company’s products, and harm the Company’s business and results of operations.

During the six months ended June 30, 2021, the Company believes the COVID-19 pandemic did impact its operating results. However, the Company has not observed any impairments of its assets or a significant change in the fair value of its assets due to the COVID-19 pandemic. At this time, it is not possible for the Company to predict the duration or magnitude of the adverse results of the outbreak and its effects on the Company’s business or results of operations, financial condition, or liquidity.

The Company has been following the recommendations of health authorities to minimize exposure risk for its team members, including the temporary closure of its corporate office and having team members work remotely. Most vendors have transitioned to electronic submission of invoices and payments.

Accounting Estimates

The preparation of financial statements in conformity with Generally Accepted Accounting Principles (“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 amounts of expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include accruals for potential liabilities, valuation of notes payable, assumptions used in deriving the fair value of derivative liabilities, valuation of equity instruments issued for compensation and services and realization of deferred tax assets. Actual results could differ from those estimates.

Stock-Based Compensation

The Company accounts for share-based awards to employees and nonemployees and consultants in accordance with the provisions of ASC 718, Compensation-Stock Compensation. Stock-based compensation cost is measured at fair value on the grant date and that fair value is recognized as expense over the requisite service, or vesting, period.

9

Fair Value of Financial Instruments

FASB Accounting Standards Codification ("ASC") 820-10 requires entities to disclose the fair value of financial instruments, both assets and liabilities recognized and not recognized on the balance sheet for which it is practicable to estimate fair value. ASC 820-10 defines the fair value of a financial instrument as the amount at which the instrument could be exchanged in a current transaction between willing parties.

The three levels of the fair value hierarchy are as follows:

Level 1	Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access.
Level 2	Valuations based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities.
Level 3	Valuations based on inputs that are unobservable, supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The carrying amount of the Company’s derivative liability of $842,000 at June 30, 2021 and $383,000 at December 31, 2020 was based on Level 2 measurements.

The carrying amounts of the Company’s other financial assets and liabilities, such as cash, prepaid expense, accounts payable and accrued expenses approximate their fair values because of the short maturity of these instruments.

Derivative Financial Instruments

The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value and is then re-valued at each reporting date, with changes in the fair value reported in the consolidated statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative instrument liabilities are classified in the balance sheet as current or non-current based on whether or not net-cash settlement of the derivative instrument could be required within 12 months of the balance sheet date. The fair value of the embedded derivatives are determined using a Binomial valuation method at inception and on subsequent valuation dates.

Net Loss Per Share

Basic earnings (loss) per share is computed using the weighted-average number of common shares outstanding during the period. Common stock issuable is considered to be outstanding in the calculation from the date of grant. Diluted earnings (loss) per share is computed using the weighted-average number of common shares and the dilutive effect of contingent shares outstanding during the period. Potentially dilutive contingent shares, which primarily consist of convertible notes, stock issuable to the exercise of stock options and warrants have been excluded from the diluted loss per share calculation because their effect is anti-dilutive.

Segments

The Company determined its reporting units in accordance with ASC 280, “Segment Reporting” (“ASC 280”). Management evaluates a reporting unit by first identifying its’ operating segments under ASC 280. The Company then evaluates each operating segment to determine if it includes one or more components that constitute a business. If there are components within an operating segment that meet the definition of a business, the Company evaluates those components to determine if they must be aggregated into one or more reporting units. If applicable, when determining if it is appropriate to aggregate different operating segments, the Company determines if the segments are economically similar and, if so, the operating segments are aggregated.

Management has determined that the Company has one consolidated operating segment. The Company’s reporting segment reflects the manner in which its chief operating decision maker reviews results and allocates resources. The Company’s reporting segment meets the definition of an operating segment and does not include the aggregation of multiple operating segments.

Recent Accounting Pronouncements

In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. Under ASU 2020-06, the embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815, or that do not result in substantial premiums accounted for as paid-in capital. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. The new guidance also requires the if-converted method to be applied for all convertible instruments. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021, with early adoption permitted. Adoption of the standard requires using either a modified retrospective or a full retrospective approach. Effective January 1, 2021, we early adopted ASU 2020-06 using the modified retrospective approach. Adoption of the new standard resulted in a decrease to additional paid-in capital of $4,519,000 (see Note 4).

In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt-Modifications and Extinguishments (Subtopic 470-50), Compensation-Stock Compensation (Topic 718), and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options. ASU 2021-04 provides clarification and reduces diversity in an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options (such as warrants) that remain equity classified after modification or exchange. An issuer measures the effect of a modification or exchange as the difference between the fair value of the modified or exchanged warrant and the fair value of that warrant immediately before modification or exchange. ASU 2021-04 introduces a recognition model that comprises four categories of transactions and the corresponding accounting treatment for each category (equity issuance, debt origination, debt modification, and modifications unrelated to equity issuance and debt origination or modification). ASU 2021-04 is effective for all entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. An entity should apply the guidance provided in ASU 2021-04 prospectively to modifications or exchanges occurring on or after the effective date. Early adoption is permitted for all entities, including adoption in an interim period. If an entity elects to early adopt ASU 2021-04 in an interim period, the guidance should be applied as of the beginning of the fiscal year that includes that interim period. The adoption of ASU 2021-04 is not expected to have a material impact on the Company’s financial statements or disclosures.

11

Other recent accounting pronouncements issued by the FASB, including its Emerging Issues Task Force, the American Institute of Certified Public Accountants, and the Securities and Exchange Commission (the “SEC”) did not or are not believed by management to have a material impact on the Company’s present or future consolidated financial statements.

Adoption of ASU 2020-06

In fiscal 2020, the Company recorded a note/debt discount of $4,745,000 to account for the beneficial conversion feature that existed on the date of issuance for the above convertible notes payable.

13

As a result of the adoption of ASU 2020-06, the Company extinguished the previously recorded debt discount of $4,745,000 by charging the opening additional paid in capital at January 1, 2021.

As of June 30, 2021 and December 31, 2020, the outstanding balance of this credit line amounted to $31,000 respectively.

Note 6 - Derivative Liability

During the year ended December 31, 2020, the Company issued certain warrants that contained a fundamental transaction provision that could give rise to an obligation to pay cash to the warrant holder upon occurrence of certain change in control type events.

In accordance with ASC 815, the fair value of these warrants are classified as a liability in the Consolidated Balance Sheet and will be re-measured at the end of every reporting period with the change in value reported in the statement of operations.

The derivative liabilities were valued using a Binomial pricing model with the following average assumptions:

	June 30, 2021			December 31, 2020
Stock Price	$	15.50		$	7.21
Risk-free interest rate		0.87	%		0.36	%
Expected volatility		135	%		135	%
Expected life (in years)	4.33 years			4.60 years
Expected dividend yield		-			-
Fair Value:
Warrants	$	842,000		$	383,000

The risk-free interest rate was based on rates established by the Federal Reserve Bank. The Company uses the historical volatility of its common stock to estimate the future volatility for its common stock. The expected life of the derivative securities was determined by the remaining contractual life of the derivative instrument. For derivative instruments that already matured, the Company used the estimated life. The expected dividend yield was based on the fact that the Company has not paid dividends to its common stockholders in the past and does not expect to pay dividends to its common stockholders in the future.

During the six months ended June 30, 2021, the Company recognized an expense of $459,000 to account for the change in fair value of the derivative liability.

Note 10 - Commitments and Contingencies

1. Litigation 

We are involved in certain legal proceedings that arise from time to time in the ordinary course of our business. Except for income tax contingencies, we record accruals for contingencies to the extent that our management concludes that the occurrence is probable and that the related amounts of loss can be reasonably estimated. Legal expenses associated with the contingency are expensed as incurred. There is no current or pending litigation of any significance with the exception of the matters that have arisen under, and are being handled in, the normal course of business. 

a.	On August 28, 2019, a complaint was filed in the Superior Court of California, County of Los Angeles, West Judicial District, Santa Monica Courthouse, Unlimited Civil Division by Jeffrey Lion, an individual (“Lion”), and by Daniel Vallera, an individual (“Vallera”). Lion and Vallera are referred to jointly as the “Plaintiffs”. The complaint was filed against GT Biopharma, Inc. and its subsidiary Oxis Biotech, Inc. (either of them or jointly, the “Company”).

Any forward-looking statements in the Form 10-Q are made only as of the date hereof and, except as may be required by law, we do not have any obligation to publicly update any forward-looking statements contained in this Form 10-Q to reflect subsequent events or circumstances.

Throughout this Quarterly Report on Form 10-Q, the terms “GTBP,” “we,” “us,” “our,” “the company” and “our company” refer to GT Biopharma, Inc., a Delaware corporation formerly known as Oxis International, Inc., DDI Pharmaceuticals, Inc. and Diagnostic Data, Inc, together with our subsidiaries.

Overview

We are a clinical stage biopharmaceutical company focused on the development and commercialization of novel immuno-oncology products based off our proprietary Tri-specific Killer Engager (TriKE™) fusion protein immune cell engager technology platform. Our TriKE platform generates proprietary therapeutics designed to harness and enhance the cancer killing abilities of a patient’s own natural killer cells, or NK cells. Once bound to an NK cell, our moieties are designed to enhance the NK cell, and precisely direct it to one or more specifically-targeted proteins expressed on a specific type of cancer cell or virus infected cell, ultimately resulting in the targeted cell’s death. TriKE can be designed to target any number of tumor antigens on hematologic malignancies, sarcomas or solid tumors and do not require patient-specific customization.

We are using our TriKE platform with the intent to bring to market immuno-oncology products that can treat a range of hematologic malignancies, sarcoma and solid tumors. The platform is scalable, and we are putting processes in place to be able to produce IND-ready moieties in a timely manner after a specific TriKE conceptual design. After conducting market and competitive research, specific moieties can then be advanced into the clinic on our own or through potential collaborations with larger companies. We are also evaluating, in conjunction with our Scientific Advisory Board, additional moieties designed to target different tumor antigens. We believe our TriKE may have the ability, if approved for marketing, to be used as a monotherapy, augment the current monoclonal antibody therapeutics, be used in conjunction with more traditional cancer therapy and potentially overcome certain limitations of current chimeric antigen receptor, or CAR-T, therapy.

We are also using our TriKE platform to develop therapeutics useful for the treatment of infectious disease such as for the treatment of patients infected by the human immunodeficiency virus (HIV). While the use of anti-retroviral drugs has substantially improved the health and increased the longevity of individuals infected with HIV, these drugs are designed to suppress virus replication to help modulate progression to AIDS and to limit further transmission of the virus. Despite the use of anti-retroviral drugs, infected individuals retain reservoirs of latent HIV-infected cells that, upon cessation of anti-retroviral drug therapy, can reactivate and re-establish an active HIV infection. For a curative therapy, destruction of these latent HIV infected cells must take place. The HIV-TriKE contains the antigen binding fragment (Fab) from a broadly-neutralizing antibody targeting the HIV-Env protein. The HIV-TriKE is designed to target HIV while redirecting NK cell killing specifically to actively replicating HIV infected cells. The HIV-TriKE induced NK cell proliferation, and demonstrated the ability in vitro to reactivate and kill HIV-infected T-cells. These findings indicate a potential role for the HIV-TriKE in the reactivation and elimination of the latently infected HIV reservoir cells by harnessing the NK cell’s ability to mediate the antibody-directed cellular cytotoxicity (ADCC).

21

Our initial work has been conducted in collaboration with the Masonic Cancer Center at the University of Minnesota under a program led by Dr. Jeffrey Miller, the Deputy Director. Dr. Miller is a recognized leader in the field of NK cell and IL-15 biology and their therapeutic potential. We have exclusive rights to the TriKE platform and are generating additional intellectual property.

As such, 2,502,518 shares of common stock were granted to these consultants with a fair value of $9,679,000. Pursuant to current accounting guidelines, as the grant of the common stock is subject to milestone or performance conditions, the Company measured the fair value of the common stock on the respective date of the agreement, and then such award was recorded as compensation expense as the milestone or performance condition was met and in accordance with its vesting term of the grant.

During the period ended June 30, 2021, pursuant to the vesting terms of the agreements, the Company issued 1,900,060 shares of common stock to these consultants.

Results of Operations

Comparison of the Three Months Ended June 30, 2021 and 2020

Research and Development Expenses

During the three months ended June 30, 2021 and 2020, we incurred $639,000 and $12,000 research and development expenses, an increase of $627,000. Research and development costs increased due primarily to the admittance of additional patients into the phase one/two clinical trial. We anticipate our direct clinical costs to increase in the remainder of 2021 upon the continuation of a phase one/two clinical trial of our most advanced TriKe product candidate, OXS-3550.

Selling, general and administrative expenses

During the three months ended June 30, 2021 and 2020, we incurred $3,742,000 and $1,546,000 of selling, general and administrative expenses. The increase of $2,196,000 in selling, general and administrative expenses is primarily attributable the increase in stock-based compensation. In the period ended June 30, 2021 we incurred $3,742,000 of stock-based compensation, we incurred $147,000 in stock-based compensation expense during 2020.

Change in fair value of derivative liability

Change in fair value of derivative liability was an expense of $480,000 for the three months ended June 30, 2021 and we had no such gain or loss for the same period in 2020.

Settlement expense

Settlement expense was an expense of $11,206,000 for the three months ended June 30, 2020 and we had no such gain or loss for the same period in 2021.

23

Interest Expense

Interest expense was $0 and $4,658,000 for the three months ended June 30, 2021 and 2020 respectively. The decrease is primarily due to the decrease in the amount of outstanding convertible notes, as these convertible notes were converted on February 16, 2021.

Comparison of the Six Months Ended June 30, 2021 and 2020

Research and Development Expenses

During the six months ended June 30, 2021 and 2020, we incurred $2,279,000 and $336,000 research and development expenses, an increase of $2,245,400. Research and development costs increased due primarily to the issuance of 190,000 shares of common stock as payment of a fee valued at $1,943,000 and the admittance of additional patients into the phase one/two clinical trial. We anticipate our direct clinical costs to increase in the remainder of 2021 upon the continuation of a phase one/two clinical trial of our most advanced TriKe product candidate, OXS-3550.

Selling, general and administrative expenses

During the six months ended June 30, 2021 and 2020, we incurred $31,104,000 and $2,292,000 of selling, general and administrative expenses. The increase of $28,812,000 in selling, general and administrative expenses is primarily attributable the increase in stock-based compensation. In the period ended June 30, 2021 we incurred $25,007,000 of stock-based compensation, we incurred no such expenses during 2020.

Change in fair value of derivative liability

Change in fair value of derivative liability was an expense of $459,000 for the six months ended June 30, 2021 and we had no such gain or loss for the same period in 2020.

Settlement expense

Settlement expense was an expense of $11,206,000 for the six months ended June 30, 2020 and we had no such gain or loss for the same period in 2021.

Interest Expense

Interest expense was $696,000 and $5,296,000 for the six months ended June 30, 2021 and 2020 respectively. The decrease is primarily due to the decrease in the amount of outstanding convertible notes, as the entire balances of convertible notes were converted on February 16, 2021.

Liquidity and Capital Resources

The Company’s current operations have focused on business planning, raising capital, establishing an intellectual property portfolio, hiring, and conducting preclinical studies and clinical trials. The Company does not have any product candidates approved for sale and has not generated any revenue from product sales. The Company has sustained operating losses since inception and expects such losses to continue over the foreseeable future. During the six months ended June 30, 2021, the Company raised the net amount of $24.7 million through issuance of common stock, raised $16.3 million through the exercise of warrants and raised $1.2 million from a series of issuances of convertible notes as compared to a total of $4.5 million raised through issuance of convertible notes payable during the same period in 2020. We anticipate that cash utilized for selling, general and administrative expenses will range between $1 and $2 million in the coming quarters, while research and development expenses will vary depending on clinical activities.

The financial statements of the Company have been prepared on a going-concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. Accordingly, the financial statements do not include any adjustments that might be necessary should the Company be unable to continue in existence.

The Company has incurred substantial losses and has cash of $39.5 million as of June 30, 2021. The Company anticipates incurring additional losses until such time, if ever, that it can generate significant sales or revenue from out-licensing of its products currently in development. Substantial additional financing will be needed by the Company to fund its operations and to commercially develop its product candidates. These factors raise substantial doubt about the Company’s ability to continue as a going concern.

24

Management is currently evaluating different strategies to obtain the required funding for future operations. These strategies may include but are not limited to: public offerings of equity and/or debt securities, payments from potential strategic research and development, licensing and/or marketing arrangements with pharmaceutical companies. Management has also implemented cost saving efforts, including reduction in executive salaries and reduced travel. Management believes that these ongoing and planned financing endeavors, if successful, will provide adequate financial resources to continue as a going concern for at least the next nine months from the date the financial statements are issued; however, there can be no assurance in this regard. If the Company is unable to secure adequate additional funding, its business, operating results, financial condition and cash flows may be materially and adversely affected.

Critical Accounting Policies

We consider the following accounting policies to be critical given they involve estimates and judgments made by management and are important for our investors’ understanding of our operating results and financial condition.

Basis of Presentation and Principles of Consolidation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, Oxis Biotech, Inc. and Georgetown Translational Pharmaceuticals, Inc. Intercompany transactions and balances have been eliminated in consolidation.

Reverse Stock Split

On February 10, 2021, the Company completed a 1:17 reverse stock split of the Company's issued and outstanding shares of common stock and all fractional shares were rounded up. All share and per share amounts in the accompanying financial statements have been adjusted retroactively to reflect the reverse stock split as if it had occurred at the beginning of the earliest period presented.

Accounting Estimates

The preparation of financial statements in conformity with Generally Accepted Accounting Principles (“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 amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include accruals for potential liabilities, valuation of notes payable, assumptions used in deriving the fair value of derivative liabilities, share-based compensation and beneficial conversion feature of notes payable, and valuation of deferred tax assets. Actual results could differ from those estimates.

Stock-Based Compensation

The Company accounts for share-based awards to employees and nonemployees and consultants in accordance with the provisions of ASC 718, Compensation-Stock Compensation. Stock-based compensation cost is measured at fair value on the grant date and that fair value is recognized as expense over the requisite service, or vesting, period.

The Company values its equity awards using the Black-Scholes option pricing model, and accounts for forfeitures when they occur. Use of the Black-Scholes option pricing model requires the input of subjective assumptions including expected volatility, expected term, and a risk-free interest rate. The Company estimates volatility using as its own historical stock price volatility. The expected term of the instrument is estimated by using the simplified method to estimate expected term. The risk-free interest rate is estimated using comparable published federal funds rates.

25

Inflation

We believe that inflation has not had a material adverse impact on our business or operating results during the periods presented.

Off-balance Sheet Arrangements

We have no off-balance sheet arrangements as of June 30, 2021.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

This company qualifies as a smaller reporting company, as defined in 17 C.F.R. §229.10(f)(1) and is not required to provide information by this Item.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our principal executive officer and principal financial officer evaluated the effectiveness of our “disclosure controls and procedures” (as such term is defined in Rules 13a-15(e) and 15d-15(e) of the United States Securities Exchange Act of 1934, as amended (the “Exchange Act”)), as of June 30, 2021. Based on that evaluation we have concluded that our disclosure controls and procedures were not effective as of June 30, 2021 as a result of material weaknesses in internal control over financial reporting due to (i) inadequate segregation of duties, (ii) risks of executive override and (iii) insufficient written policies and procedures for accounting and financial reporting with respect to the requirements and application of both U.S. GAAP and SEC regulation, in each case, as described in “Item 9A. Controls and Procedures” in the Company’s Form 10-K for the year ended December 31, 2020.

The Company is taking steps, and intends to take additional steps, to mitigate the issues identified and implement a functional system of internal control over financial reporting. Such measures will include, but not be limited to: hiring of additional employees in our finance and accounting department; preparation of risk-control matrices to identify key risks and develop and document policies to mitigate those risks; and identification and documentation of standard operating procedures for key financial and SEC reporting activities.

Changes in Internal Control over Financial Reporting

Except for the ongoing remediation of the material weaknesses in internal controls over financial reporting noted above, no changes in our internal control over financial reporting were made during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Note 2. Going Concern

Note 2 -Going Concern

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of business. As reflected in the accompanying consolidated financial statements, for the six months ended June 30, 2021, the Company incurred a net loss of $34.5 million and used cash in operating activities of $8.0 million. These factors raise substantial doubt about the Company’s ability to continue as a going concern within one year of the date that these financial statements are issued. The consolidated financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern. In addition, our independent registered public accounting firm, in their report on our audited financial statements for the year ended December 31, 2020, raised substantial doubt about the Company’s ability to continue as a going concern.

During the six months ended June 30, 2021, the Company received net cash of $24.7 million from the sale of 4,945,000 shares of its common stock pursuant to a public offering, issuance of notes payable for cash of $1.2 million and $16.3 million in cash from exercise of warrants for a total cash received of $42 million. At June 30, 2021, the Company had cash on hand in the amount of $39.5 million. The Company’s current operations have focused on business planning, raising capital, establishing an intellectual property portfolio, hiring, and conducting preclinical studies and clinical trials. The Company does not have any product candidates approved for sale and has not generated any revenue from product sales. The Company has sustained operating losses since inception and expects such losses to continue over the foreseeable future. Management is currently evaluating different strategies to obtain the required funding for future operations. These strategies may include but are not limited to: public offerings of equity and/or debt securities, payments from potential strategic research and development, and licensing and/or marketing arrangements with pharmaceutical companies. If the Company is unable to secure adequate additional funding, its business, operating results, financial condition and cash flows may be materially and adversely affected. Management estimates that the current funds on hand will be sufficient to continue operations through the next six months. The Company’s ability to continue as a going concern is dependent upon its ability to continue to implement its business plan.

Note 3 - Summary of Significant Accounting Policies

Basis of Presentation

The accompanying condensed consolidated financial statements are unaudited. These unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020 filed with the SEC on April 16, 2021 (the “2020 Annual Report”). The consolidated balance sheet as of December 31, 2020 included herein was derived from the audited consolidated financial statements as of that date.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments necessary to fairly present the Company’s financial position and results of operations for the interim periods reflected. Except as noted, all adjustments contained herein are of a normal recurring nature. Results of operations for the fiscal periods presented herein are not necessarily indicative of fiscal year-end results.

Basis of Presentation and Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, Oxis Biotech, Inc. and Georgetown Translational Pharmaceuticals, Inc. Intercompany transactions and balances have been eliminated in consolidation.

Reverse Stock Split

On February 10, 2021, the Company completed a 1:17 reverse stock split of the Company's issued and outstanding shares of common stock and all fractional shares were rounded up. All share and per share amounts in the accompanying financial statements have been adjusted retroactively to reflect the reverse stock split as if it had occurred at the beginning of the earliest period presented.

COVID-19

In March 2020, the World Health Organization declared coronavirus COVID-19 a global pandemic. This contagious disease outbreak, which has continued to spread, has adversely affected workforces, customers, economies, and financial markets globally. It has also disrupted the normal operations of many businesses. This outbreak could decrease spending, adversely affect demand for the Company’s products, and harm the Company’s business and results of operations.

During the six months ended June 30, 2021, the Company believes the COVID-19 pandemic did impact its operating results. However, the Company has not observed any impairments of its assets or a significant change in the fair value of its assets due to the COVID-19 pandemic. At this time, it is not possible for the Company to predict the duration or magnitude of the adverse results of the outbreak and its effects on the Company’s business or results of operations, financial condition, or liquidity.

The Company has been following the recommendations of health authorities to minimize exposure risk for its team members, including the temporary closure of its corporate office and having team members work remotely. Most vendors have transitioned to electronic submission of invoices and payments.

Accounting Estimates

The preparation of financial statements in conformity with Generally Accepted Accounting Principles (“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 amounts of expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include accruals for potential liabilities, valuation of notes payable, assumptions used in deriving the fair value of derivative liabilities, valuation of equity instruments issued for compensation and services and realization of deferred tax assets. Actual results could differ from those estimates.

Stock-Based Compensation

The Company accounts for share-based awards to employees and nonemployees and consultants in accordance with the provisions of ASC 718, Compensation-Stock Compensation. Stock-based compensation cost is measured at fair value on the grant date and that fair value is recognized as expense over the requisite service, or vesting, period.

Fair Value of Financial Instruments

FASB Accounting Standards Codification ("ASC") 820-10 requires entities to disclose the fair value of financial instruments, both assets and liabilities recognized and not recognized on the balance sheet for which it is practicable to estimate fair value. ASC 820-10 defines the fair value of a financial instrument as the amount at which the instrument could be exchanged in a current transaction between willing parties.

The three levels of the fair value hierarchy are as follows:

Level 1	Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access.
Level 2	Valuations based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities.
Level 3	Valuations based on inputs that are unobservable, supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The carrying amount of the Company’s derivative liability of $842,000 at June 30, 2021 and $383,000 at December 31, 2020 was based on Level 2 measurements.

The carrying amounts of the Company’s other financial assets and liabilities, such as cash, prepaid expense, accounts payable and accrued expenses approximate their fair values because of the short maturity of these instruments.

Derivative Financial Instruments

The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value and is then re-valued at each reporting date, with changes in the fair value reported in the consolidated statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative instrument liabilities are classified in the balance sheet as current or non-current based on whether or not net-cash settlement of the derivative instrument could be required within 12 months of the balance sheet date. The fair value of the embedded derivatives are determined using a Binomial valuation method at inception and on subsequent valuation dates.

Net Loss Per Share

Basic earnings (loss) per share is computed using the weighted-average number of common shares outstanding during the period. Common stock issuable is considered to be outstanding in the calculation from the date of grant. Diluted earnings (loss) per share is computed using the weighted-average number of common shares and the dilutive effect of contingent shares outstanding during the period. Potentially dilutive contingent shares, which primarily consist of convertible notes, stock issuable to the exercise of stock options and warrants have been excluded from the diluted loss per share calculation because their effect is anti-dilutive.

These following common stock equivalents were excluded in the computation of the net loss per share because their effect is anti-dilutive.

	June 30, 2021		June 30, 2020
A. Options to purchase common stock		-		3
B. Warrants to purchase common stock		2,365,473		106,650
C. Convertible notes payable		-		4,678,823
D. Convertible Series J-1 Preferred stock		-		692,220
E. Convertible Series C Preferred stock		7		7
		2,365,480		5,477,703

Segments

The Company determined its reporting units in accordance with ASC 280, “Segment Reporting” (“ASC 280”). Management evaluates a reporting unit by first identifying its’ operating segments under ASC 280. The Company then evaluates each operating segment to determine if it includes one or more components that constitute a business. If there are components within an operating segment that meet the definition of a business, the Company evaluates those components to determine if they must be aggregated into one or more reporting units. If applicable, when determining if it is appropriate to aggregate different operating segments, the Company determines if the segments are economically similar and, if so, the operating segments are aggregated.

Management has determined that the Company has one consolidated operating segment. The Company’s reporting segment reflects the manner in which its chief operating decision maker reviews results and allocates resources. The Company’s reporting segment meets the definition of an operating segment and does not include the aggregation of multiple operating segments.

Recent Accounting Pronouncements

In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. Under ASU 2020-06, the embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815, or that do not result in substantial premiums accounted for as paid-in capital. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. The new guidance also requires the if-converted method to be applied for all convertible instruments. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021, with early adoption permitted. Adoption of the standard requires using either a modified retrospective or a full retrospective approach. Effective January 1, 2021, we early adopted ASU 2020-06 using the modified retrospective approach. Adoption of the new standard resulted in a decrease to additional paid-in capital of $4,519,000 (see Note 4).

In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt-Modifications and Extinguishments (Subtopic 470-50), Compensation-Stock Compensation (Topic 718), and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options. ASU 2021-04 provides clarification and reduces diversity in an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options (such as warrants) that remain equity classified after modification or exchange. An issuer measures the effect of a modification or exchange as the difference between the fair value of the modified or exchanged warrant and the fair value of that warrant immediately before modification or exchange. ASU 2021-04 introduces a recognition model that comprises four categories of transactions and the corresponding accounting treatment for each category (equity issuance, debt origination, debt modification, and modifications unrelated to equity issuance and debt origination or modification). ASU 2021-04 is effective for all entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. An entity should apply the guidance provided in ASU 2021-04 prospectively to modifications or exchanges occurring on or after the effective date. Early adoption is permitted for all entities, including adoption in an interim period. If an entity elects to early adopt ASU 2021-04 in an interim period, the guidance should be applied as of the beginning of the fiscal year that includes that interim period. The adoption of ASU 2021-04 is not expected to have a material impact on the Company’s financial statements or disclosures.

Other recent accounting pronouncements issued by the FASB, including its Emerging Issues Task Force, the American Institute of Certified Public Accountants, and the Securities and Exchange Commission (the “SEC”) did not or are not believed by management to have a material impact on the Company’s present or future consolidated financial statements.

The debt discount is being amortized to interest expense over the term of the corresponding convertible notes payable. At December 31, 2020, the Company had recorded an unamortized note/debt discount of $4,519,000.

On January 1, 2021 the Company chose to adopt Accounting Standards Update (“ASU”) 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. Under ASU 2020-06, the embedded conversion features are no longer required to be separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815, or that do not result in substantial premiums accounted for as paid-in capital.

As a result of the adoption of ASU 2020-06, the Company extinguished the previously recorded debt discount of $4,745,000 by charging the opening additional paid in capital at January 1, 2021. In addition, the Company also adjusted accumulated deficit to account for the derecognition of the $226,000 interest expense due to the amortization of the debt discount that was recorded in fiscal 2020. As a result of these adjustments, the unamortized debt discount of $4,519,000 was extinguished.

Convertible Notes Payable

Note 6. Derivative Liability

Note 6 - Derivative Liability

During the year ended December 31, 2020, the Company issued certain warrants that contained a fundamental transaction provision that could give rise to an obligation to pay cash to the warrant holder upon occurrence of certain change in control type events.

In accordance with ASC 815, the fair value of these warrants are classified as a liability in the Consolidated Balance Sheet and will be re-measured at the end of every reporting period with the change in value reported in the statement of operations.

The derivative liabilities were valued using a Binomial pricing model with the following average assumptions:

	June 30, 2021			December 31, 2020
Stock Price	$	15.50		$	7.21
Risk-free interest rate		0.87	%		0.36	%
Expected volatility		135	%		135	%
Expected life (in years)	4.33 years			4.60 years
Expected dividend yield		-			-
Fair Value:
Warrants	$	842,000		$	383,000

The risk-free interest rate was based on rates established by the Federal Reserve Bank. The Company uses the historical volatility of its common stock to estimate the future volatility for its common stock. The expected life of the derivative securities was determined by the remaining contractual life of the derivative instrument. For derivative instruments that already matured, the Company used the estimated life. The expected dividend yield was based on the fact that the Company has not paid dividends to its common stockholders in the past and does not expect to pay dividends to its common stockholders in the future.

During the six months ended June 30, 2021, the Company recognized an expense of $459,000 to account for the change in fair value of the derivative liability.

Common Stock Issuable

As a result, of the mandatory conversion of the notes payable and accrued interest in the aggregate of $38,799,000 on February 16, 2021, the Company is obligated to issue a total of 11,413,809 shares of common stock to the respective noteholders.

As of June 30, 2021, the Company was only able to issue 8,261,809 shares of common stock or approximately 72% or $28,083,000 of the converted notes payable and accrued interest to the respective noteholders. With regards to the remaining 3,152,000 unissued shares of common stock, the Company is in the process of obtaining the necessary supporting documentation from the respective noteholders which will then be provided to the Company’s stock transfer agent as a requirement for the issuance of the common stock certificate.

For financial reporting purposes, the Company reported $10,716,000 as common stock issuable in the accompanying statements of stockholders equity to account for the estimated balance of the converted notes payable and accrued interest for which the Company has not yet issued the corresponding common stock.

Subsequent to June 30, 2021, the Company issued a total of 2,313,116 shares of common stock to these noteholders upon submission of the required documentation to the Company’s stock transfer agent.

Common Stock

The following were transactions during the six months ended June 30, 2021:

Issuance of Common Stock in public offering

On February 16, 2021, the Company completed a public offering of 4,945,000 shares of common stock for net proceeds of $24,679,000, after deducting underwriting discounts, commissions and other direct offering expenses. As part of the offering, the Company also granted these investors, warrants to purchase 5,192,250 shares of common stock. The warrants are fully vested, exercisable at $5.50 per share and will expire in five years.

As a result of the completion of the public offering and the listing of its shares of common stock on the Nasdaq Capital Markets, convertible notes payable and accrued interest with an aggregate amount of $38,799,000 were mandatorily converted at its stated conversion rate of $3.40 per share into 11,413,809 shares of the Company’s common stock (see Note 4).

Issuance of Common Stock for services - consultants

As part of consulting agreements with certain consultants, the Company agreed to grant these consultants common stock equal to 1% and 3% of the fully diluted shares of common stock of the Company upon conversion of options, warrants and Convertible Notes in association with a national markets qualified financing as consideration for entering into the Agreement (with such stock to vest and be delivered within 30 days after the national markets qualified financing). Pursuant to the agreement, approximately 75% of the common stock to be issued will vest immediately while the remaining 25% will vest over a period of two years.

On February 16, 2021, the Company completed its equity offering and listed its shares of common stock on the Nasdaq Capital Markets. As such, 2,502,518 shares of common stock were granted to these consultants with a fair value of $9,679,000. Pursuant to current accounting guidelines, as the grant of the common stock is subject to milestone or performance conditions, the Company measured the fair value of the common stock on the respective date of the agreement, and then such award was recorded as compensation expense as the milestone or performance condition was met and in accordance with its vesting term of the grant.

During the period ended June 30, 2021, pursuant to the vesting terms of the agreements, the Company issued 1,900,060 shares of common stock with a grant date fair value of $7,564,000 to these consultants. In addition, the Company also issued 150,000 shares of fully vested common stock with a fair value of $1,213,000 to other consultants for service rendered. As a result, the Company issued a total of 2,050,060 shares of common stock and recognized stock compensation expense of $8,779,000 to account the fair value of common stock that vested.

As of June 30, 2021, the unvested and unissued common stock totaled 602,458 shares of common stock with an estimated fair value of $2,115,000 that will be recognized as stock compensation in future periods based upon the remaining vesting term of the grant.

The conversion ratio is based on the average closing bid price of the common stock for the fifteen consecutive trading days ending on the date immediately preceding the date notice of conversion is given, but cannot be less than $3.40 or more than $4.9113. The conversion ratio may be adjusted under certain circumstances such as stock splits or stock dividends. The Company has the right to automatically convert the Series C Preferred Stock into common stock if the Company lists its shares of common stock on the Nasdaq National Market and the average closing bid price of the Company’s common stock on the Nasdaq National Market for 15 consecutive trading days exceeds $3,000.00. Each share of Series C Preferred Stock is entitled to the number of votes equal to 0.26 divided by the average closing bid price of the Company’s common stock during the fifteen consecutive trading days immediately prior to the date such shares of Series C Preferred Stock were purchased. In the event of liquidation, the holders of the Series C Preferred Stock shall participate on an equal basis with the holders of the common stock (as if the Series C Preferred Stock had converted into common stock) in any distribution of any of the assets or surplus funds of the Company.

In the first quarter of 2019, it was discovered that a certificate of designation with respect to the Series J Preferred Stock had never been filed with the Office of the Secretary of State for the State of Delaware.

Shares of the Series J-1 Preferred Stock are convertible at any time, at the option of the holders, into shares of the Company’s common stock at an effective conversion price of $3.40 per share, subject to adjustment for, among other things, stock dividends, stock splits, combinations, reclassifications of our capital stock and mergers or consolidations, and subject to a beneficial ownership limitation which prohibits conversion if such conversion would result in the holder (together with its affiliates) being the beneficial owner of in excess of 9.99% of the Company’s common stock or 692,220 shares of common stock. Shares of the Series J-1 Preferred Stock have the same voting rights a shares of the Company’s common stock, with the holders of the Series J-1 Preferred Stock entitled to vote on an as-converted-to-common stock basis, subject to the beneficial ownership limitation described above, together with the holders of the Company’s common stock on all matters presented to the Company’s stockholders. The Series J-1 Preferred Stock are not entitled to any dividends (unless specifically declared by the Board), but will participate on an as-converted-to-common-stock basis in any dividends to the holders of the Company’s common stock. In the event of the Company’s dissolution, liquidation or winding up, the holders of the Series J-1 Preferred Stock will be on parity with the holders of the Company’s common stock and will participate, on a on an as-converted-to-common stock basis, in any distribution to holders of the Company’s common stock. As of December 31, 2020, total Series J-1 Preferred Stock issued and outstanding totaled 2,353,548 shares.

On February 16, 2021, as a result of the completion of the public offering and the listing of its shares of common stock on the Nasdaq Capital Markets, the entire 2,353,548 shares of Series J-1 Preferred Stock were mandatorily converted at a conversion rate of $3.40 per share into 692,220 shares of the Company’s common stock. As of June 30, 2021, there were no shares of Series J-1 Preferred stock issued and outstanding.

C. Series K Preferred Stock

On February 16, 2021, the Board designated 115,000 shares of Series K preferred stock, par value $.01. (the “Series K Preferred Stock”).

Shares of the Series K Preferred Stock are convertible at any time, at the option of the holders, into shares of the Company’s common stock at an effective conversion rate of 100 shares of common stock for each share of Series K Preferred Stock.

Summary of Significant Accounting Policies (Policies)

6 Months Ended

Jun. 30, 2021

Organization and Operations

Basis of Presentation

The accompanying condensed consolidated financial statements are unaudited. These unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020 filed with the SEC on April 16, 2021 (the “2020 Annual Report”). The consolidated balance sheet as of December 31, 2020 included herein was derived from the audited consolidated financial statements as of that date.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments necessary to fairly present the Company’s financial position and results of operations for the interim periods reflected. Except as noted, all adjustments contained herein are of a normal recurring nature. Results of operations for the fiscal periods presented herein are not necessarily indicative of fiscal year-end results.

Basis of Presentation and Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, Oxis Biotech, Inc. and Georgetown Translational Pharmaceuticals, Inc. Intercompany transactions and balances have been eliminated in consolidation.

Reverse Stock Split

On February 10, 2021, the Company completed a 1:17 reverse stock split of the Company's issued and outstanding shares of common stock and all fractional shares were rounded up. All share and per share amounts in the accompanying financial statements have been adjusted retroactively to reflect the reverse stock split as if it had occurred at the beginning of the earliest period presented.

COVID-19

In March 2020, the World Health Organization declared coronavirus COVID-19 a global pandemic. This contagious disease outbreak, which has continued to spread, has adversely affected workforces, customers, economies, and financial markets globally. It has also disrupted the normal operations of many businesses. This outbreak could decrease spending, adversely affect demand for the Company’s products, and harm the Company’s business and results of operations.

During the six months ended June 30, 2021, the Company believes the COVID-19 pandemic did impact its operating results. However, the Company has not observed any impairments of its assets or a significant change in the fair value of its assets due to the COVID-19 pandemic. At this time, it is not possible for the Company to predict the duration or magnitude of the adverse results of the outbreak and its effects on the Company’s business or results of operations, financial condition, or liquidity.

The Company has been following the recommendations of health authorities to minimize exposure risk for its team members, including the temporary closure of its corporate office and having team members work remotely. Most vendors have transitioned to electronic submission of invoices and payments.

Accounting Estimates

The preparation of financial statements in conformity with Generally Accepted Accounting Principles (“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 amounts of expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include accruals for potential liabilities, valuation of notes payable, assumptions used in deriving the fair value of derivative liabilities, valuation of equity instruments issued for compensation and services and realization of deferred tax assets. Actual results could differ from those estimates.

Stock Based Compensation

The Company accounts for share-based awards to employees and nonemployees and consultants in accordance with the provisions of ASC 718, Compensation-Stock Compensation. Stock-based compensation cost is measured at fair value on the grant date and that fair value is recognized as expense over the requisite service, or vesting, period.

Fair Value of Financial Instruments

FASB Accounting Standards Codification ("ASC") 820-10 requires entities to disclose the fair value of financial instruments, both assets and liabilities recognized and not recognized on the balance sheet for which it is practicable to estimate fair value. ASC 820-10 defines the fair value of a financial instrument as the amount at which the instrument could be exchanged in a current transaction between willing parties.

The three levels of the fair value hierarchy are as follows:

Level 1	Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access.
Level 2	Valuations based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities.
Level 3	Valuations based on inputs that are unobservable, supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The carrying amount of the Company’s derivative liability of $842,000 at June 30, 2021 and $383,000 at December 31, 2020 was based on Level 2 measurements.

The carrying amounts of the Company’s other financial assets and liabilities, such as cash, prepaid expense, accounts payable and accrued expenses approximate their fair values because of the short maturity of these instruments.

Derivative Financial Instruments

The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value and is then re-valued at each reporting date, with changes in the fair value reported in the consolidated statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative instrument liabilities are classified in the balance sheet as current or non-current based on whether or not net-cash settlement of the derivative instrument could be required within 12 months of the balance sheet date. The fair value of the embedded derivatives are determined using a Binomial valuation method at inception and on subsequent valuation dates.

Net Loss per Share

Basic earnings (loss) per share is computed using the weighted-average number of common shares outstanding during the period. Common stock issuable is considered to be outstanding in the calculation from the date of grant. Diluted earnings (loss) per share is computed using the weighted-average number of common shares and the dilutive effect of contingent shares outstanding during the period. Potentially dilutive contingent shares, which primarily consist of convertible notes, stock issuable to the exercise of stock options and warrants have been excluded from the diluted loss per share calculation because their effect is anti-dilutive.

These following common stock equivalents were excluded in the computation of the net loss per share because their effect is anti-dilutive.

	June 30, 2021		June 30, 2020
A. Options to purchase common stock		-		3
B. Warrants to purchase common stock		2,365,473		106,650
C. Convertible notes payable		-		4,678,823
D. Convertible Series J-1 Preferred stock		-		692,220
E. Convertible Series C Preferred stock		7		7
		2,365,480		5,477,703

Segments

The Company determined its reporting units in accordance with ASC 280, “Segment Reporting” (“ASC 280”). Management evaluates a reporting unit by first identifying its’ operating segments under ASC 280. The Company then evaluates each operating segment to determine if it includes one or more components that constitute a business. If there are components within an operating segment that meet the definition of a business, the Company evaluates those components to determine if they must be aggregated into one or more reporting units. If applicable, when determining if it is appropriate to aggregate different operating segments, the Company determines if the segments are economically similar and, if so, the operating segments are aggregated.

Management has determined that the Company has one consolidated operating segment. The Company’s reporting segment reflects the manner in which its chief operating decision maker reviews results and allocates resources. The Company’s reporting segment meets the definition of an operating segment and does not include the aggregation of multiple operating segments.

Recent Accounting Pronouncements

In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. Under ASU 2020-06, the embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815, or that do not result in substantial premiums accounted for as paid-in capital. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. The new guidance also requires the if-converted method to be applied for all convertible instruments. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021, with early adoption permitted. Adoption of the standard requires using either a modified retrospective or a full retrospective approach. Effective January 1, 2021, we early adopted ASU 2020-06 using the modified retrospective approach. Adoption of the new standard resulted in a decrease to additional paid-in capital of $4,519,000 (see Note 4).

In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt-Modifications and Extinguishments (Subtopic 470-50), Compensation-Stock Compensation (Topic 718), and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options. ASU 2021-04 provides clarification and reduces diversity in an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options (such as warrants) that remain equity classified after modification or exchange. An issuer measures the effect of a modification or exchange as the difference between the fair value of the modified or exchanged warrant and the fair value of that warrant immediately before modification or exchange. ASU 2021-04 introduces a recognition model that comprises four categories of transactions and the corresponding accounting treatment for each category (equity issuance, debt origination, debt modification, and modifications unrelated to equity issuance and debt origination or modification). ASU 2021-04 is effective for all entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. An entity should apply the guidance provided in ASU 2021-04 prospectively to modifications or exchanges occurring on or after the effective date. Early adoption is permitted for all entities, including adoption in an interim period. If an entity elects to early adopt ASU 2021-04 in an interim period, the guidance should be applied as of the beginning of the fiscal year that includes that interim period. The adoption of ASU 2021-04 is not expected to have a material impact on the Company’s financial statements or disclosures.

Other recent accounting pronouncements issued by the FASB, including its Emerging Issues Task Force, the American Institute of Certified Public Accountants, and the Securities and Exchange Commission (the “SEC”) did not or are not believed by management to have a material impact on the Company’s present or future consolidated financial statements.
