NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

Predictive Oncology Inc. (“Predictive Oncology” or the “Company”) is a knowledge-driven company focused on applying artificial intelligence (“AI”) to support the development of optimal cancer therapies, which can ultimately lead to more effective treatments and improved patient outcomes. Through AI, Predictive Oncology uses its proprietary biobank of 150,000+ cancer tumor samples, categorized by patient type, against drug compounds to help the drug discovery process and increase the probability of successful drug development. The Company offers a suite of solutions for oncology drug development from early discovery to clinical trials.

Predictive Oncology’s mission is to change the landscape of oncology drug discovery and enable the development of more effective therapies for the treatment of cancer. By harnessing the power of machine learning and scientific rigor, the Company believes that it can improve the probability of success of advancing pharmaceutical and biological drug candidates with a higher degree of confidence.

The Company operates in three business areas. In its first area, the Company provides optimized, high-confidence drug-response predictions through the application of AI using its proprietary biobank of tumor samples to enable a more informed selection of drug/tumor combinations and increase the probability of success during drug development. The Company also creates and develops tumor-specific 3D cell culture models mimicking the physiological environment of human tissue enabling better-informed decision-making during development. In its second business area, the Company provides services and research using a proprietary self-contained and automated system that conducts high-throughput, self-interaction chromatography screens using additives and excipients commonly included in protein formulations resulting in soluble and physically stable formulations of biologics. The Company’s third business area produces the United States Food and Drug Administration (“FDA”)-cleared STREAMWAY® System and associated products for automated medical fluid waste management and patient-to-drain medical fluid disposal.

The Company has three reportable segments, which have been delineated by location and business area, as further described in Note 12 – Segments:

●

Pittsburgh segment: provides services that include the application of AI using its proprietary biobank of 150,000+ tumor samples. Pittsburgh also creates proprietary 3D culture models used in drug development.

●

Birmingham segment: provides contract services and research focused on solubility improvements, stability studies, and protein production.

●

Eagan segment: produces the FDA-cleared STREAMWAY System and associated products for automated medical fluid waste management and patient-to-drain medical fluid disposal.

Going Concern

These condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) assuming the Company will continue as a going concern. The going concern assumption contemplates the realization of assets and satisfaction of liabilities in the normal course of business. However, substantial doubt about the Company’s ability to continue as a going concern exists.

The Company has incurred significant and recurring losses from operations for the past several years and, as of June 30, 2024, had an accumulated deficit of $175,161,987. The Company had cash and cash equivalents of $5,331,770 as of June 30, 2024, and needs to raise significant additional capital to meet its operating needs. The Company had short-term obligations of $4,618,511 and long-term operating lease obligations of $1,860,983 as of June 30, 2024. The Company does not expect to generate sufficient operating revenue to sustain its operations in the near term. During the six months ended June 30, 2024, the Company incurred negative cash flows from operations of $6,634,072. Although the Company has attempted to improve its cash flows from operations by bolstering revenues and continues to seek ways to generate revenue through business development activities, there is no guarantee that the Company will be able to improve its cash flows from operations sufficiently or achieve profitability in the near term. As a result of these conditions, substantial doubt exists about the Company’s ability to continue as a going concern within one year after the date these condensed consolidated financial statements are issued.

The Company is evaluating alternatives to obtain the required additional funding to maintain future operations. These alternatives may include, but are not limited to, equity financing, issuing debt, entering into other financing arrangements, or monetizing operating businesses or assets. These possibilities, to the extent available, may be on terms that result in significant dilution to the Company’s existing stockholders or that result in the Company’s existing stockholders losing part or all of their investment. Despite these potential sources of funding, the Company may be unable to access financing or obtain additional liquidity when needed or under acceptable terms, if at all. If such financing or adequate funds from operations are not available, the Company would be forced to limit its business activities and the Company could default on existing payment obligations, which would have a material adverse effect on its financial condition and results of operations, and the Company may ultimately be required to cease its operations and liquidate its business. The Company’s condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern and do not include any adjustment relating to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should the Company be unable to continue in existence.

Basis of Presentation

The Company has prepared the condensed consolidated financial statements and related unaudited financial information in the notes in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim condensed consolidated financial statements. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These interim condensed consolidated financial statements reflect all adjustments consisting of normal recurring adjustments, which in the opinion of management, are necessary to present fairly the Company’s position, the results of its operations, and its cash flows for the interim periods. These interim condensed consolidated financial statements reflect all intercompany eliminations. These interim condensed consolidated financial statements should be read in conjunction with the annual consolidated financial statements and the notes thereto contained in the Annual Report on Form 10-K filed with the SEC on March 28, 2024. The nature of the Company’s business is such that the results of any interim period may not be indicative of the results to be expected for the entire year.

Accounting Policies and 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 and expenses and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and during the reporting period. Actual results could materially differ from those estimates. Estimates are used in the following areas, among others: variable consideration associated with revenue recognition, stock-based compensation expense, fair value of long-lived assets for impairment analyses, the valuation allowance included in the deferred income tax calculation, accrued expenses, and fair value of derivative liabilities.

Note 1 to the annual consolidated financial statements contained in the Annual Report on Form 10-K filed with the SEC on March 28, 2024, describes the significant accounting policies and estimates used in preparation of the consolidated financial statements. There have been no material changes in the Company’s significant accounting policies during the six months ended June 30, 2024.

Principles of Consolidation

The Company had two wholly owned subsidiaries, Helomics Corporation and Skyline Medical, Inc. (“Skyline Medical”), as of June 30, 2024, and December 31, 2023, and for the three and six months ended June 30, 2024, and 2023. The condensed consolidated financial statements include the accounts of the Company and these wholly owned subsidiaries after elimination of intercompany transactions and balances as of June 30, 2024, and December 31, 2023, and for the three and six months ended June 30, 2024, and 2023.

Concentration of Credit Risk

Financial instruments that subject the Company to credit risk primarily consist of cash and cash equivalents and accounts receivable. The Company maintains its cash and cash equivalent balances with high quality financial institutions and, consequently, the Company believes that such funds are subject to minimal credit risk. The Company is exposed to credit risk in the event of default by the financial institutions to the extent amounts recorded on the condensed consolidated balance sheets are in excess of insured limits. The Company has not experienced any credit losses in such accounts and does not believe it is exposed to any significant credit risk on these funds.

As of June 30, 2024, accounts receivable from a single customer represented 11% of the Company’s total accounts receivable. As of December 31, 2023, accounts receivable from a single customer represented 16% of the Company’s total accounts receivable.

Recent Accounting Pronouncements

The Company considers the applicability and impact of all Accounting Standards Updates (“ASUs”) issued by the Financial Accounting Standards Board (the “FASB”). Recently issued ASUs not listed below either were assessed and determined to be not applicable or are currently expected to have no impact on the condensed consolidated financial statements of the Company.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This ASU updates reportable segment disclosures by expanding the frequency and extent of segment disclosures. This ASU is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The ASU requires the retrospective adoption method. Management is currently evaluating this ASU to determine its impact on the Company’s disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU requires more detailed income tax disclosures. The guidance requires entities to disclose disaggregated information about their effective tax rate reconciliation as well as expanded information on income taxes paid by jurisdiction. The disclosure requirements will be applied on a prospective basis, with the option to apply them retrospectively. This ASU is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. Management is currently evaluating this ASU to determine its impact on the Company’s disclosures.

NOTE 2 – COLLABORATIVE ARRANGEMENTS AND CONTRACTS WITH CUSTOMERS

Collaboration Agreement with Cancer Research Horizons

On March 16, 2023, the Company entered into a Collaboration Agreement (the “CRH Agreement”) with Cancer Research Horizons (“CRH”), pursuant to which the Company used its PEDAL technology to evaluate CRH pre-clinical drug inhibitors of Glutaminase to determine which cancer types and patient populations were most likely to respond to treatment with those compounds (the “Project”). Under the CRH Agreement, both parties retained rights to their respective background intellectual property. Rights to reports, findings, supporting data, and materials (“Project Intellectual Property”) that were generated by the Company pursuant to its performance under the CRH Agreement vested exclusively in CRH. Each party funded its own participation in the Project. Costs incurred to participate in the CRH Agreement were recorded in Cost of sales in the Company’s Consolidated Statement of Net Loss for the year ended December 31, 2023.

Pursuant to the CRH Agreement, the Company shall receive a percentage of net revenue, as defined in the agreement, received by CRH for the commercialization of the CRH Candidates and any CRH Derivatives (each as defined in the CRH Agreement). The percentage of net revenue varies depending on the stage of development. The revenue sharing fees represent variable consideration, which is measured using the expected value method under ASC 606 based on the actual net revenues earned by CRH under Relevant Transfer Agreements (as defined in the CRH Agreement) relating to the CRH Candidates and CRH Derivatives. Due to the uncertainty associated with the timing and amount of revenue sharing fees, the Company concluded that the revenue sharing fees should be fully constrained until such time that Relevant Transfer Agreements have been entered and net revenues have been earned. These estimates will be reassessed at each reporting period. During the six months ended June 30, 2024, and 2023, the Company recognized no revenue under the CRH Agreement.

Contracts with Customers and Contract Balances

The Company records a receivable when it has an unconditional right to receive consideration after the performance obligations are satisfied.

NOTE 9 – DERIVATIVES

Certain warrants issued to placement agents were determined to be a derivative liability due to certain features of the warrants which could, in certain circumstances, result in the holder receiving the fair value of the outstanding warrants in the same type of consideration as the common stockholders. As a result, in those circumstances, the amount of consideration would differ from that provided to holders of common stock, therefore, the warrants were classified as a liability.

The fair value of the placement agent warrants issued in connection with the March 2020 private placement was determined to be $0 and $135 as of June 30, 2024, and December 31, 2023, respectively. The Company recorded gains on the change in fair value of the placement agent warrants of $13 and $1,900 during the three months ended June 30, 2024, and 2023, respectively, and $135 and $2,319 during the six months ended June 30, 2024, and 2023, respectively. The placement agent warrants expire in March 2025.

The fair value of the placement agent warrants issued in connection with the May 2020 offering of securities was determined to be $0 and $333 as of June 30, 2024, and December 31, 2023, respectively. The Company recorded gains on the change in fair value of the placement agent warrants of $57 and $2,435 during the three months ended June 30, 2024, and 2023, respectively, and $333 and $2,770 during the six months ended June 30, 2024, and 2023, respectively. The placement agent warrants expire in May 2025.

The placement agent warrants issued in connection with the June 2020 warrant exercise and issuance had a fair value of $8 and $908 as of June 30, 2024, and December 31, 2023, respectively. The Company recorded gains on the change in fair value of the placement agent warrants of $289 and $2,973 during the three months ended June 30, 2024, and 2023, respectively, and $900 and $3,172 during the six months ended June 30, 2024, and 2023, respectively.

NOTE 10 – STOCKHOLDERS’ EQUITY, STOCK OPTIONS AND WARRANTS

Series F Preferred Stock Dividend and Reverse Stock Split

On March 16, 2023, the Board of Directors of the Company authorized the issuance of 80,000 shares of Series F Preferred Stock, par value $0.01 per share.

On March 16, 2023, the Board of Directors of the Company declared a dividend of one one-thousandth of a share of Series F Preferred Stock, par value $0.01 per share, for each outstanding share of the Company’s common stock held on record as of March 27, 2023. 79,404 shares of Series F Preferred Stock were issued pursuant to the stock dividend. Each share of Series F Preferred Stock entitled the holder thereof to 1,000,000 votes per share to vote together with the outstanding shares of common stock of the Company as a single class to adopt an amendment to the Company’s Certificate of Incorporation to affect a reverse stock split.

On April 19, 2023, the Company completed a one-for-twenty reverse stock split that was effective for trading purposes on April 24, 2023. No fractional shares were issued as a result of the reverse stock split. Any fractional shares that would otherwise have resulted from the reverse stock split were rounded up to the next whole number. The number of authorized shares of common stock under the Company’s certificate of incorporation, as amended, remained unchanged at 200,000,000 shares. All numbers of shares and per-share amounts in this report have been adjusted to reflect the reverse split. Proportionate reductions were made to the number of shares of common stock reserved for future issuance under our 2012 Equity Incentive Plan and the number of shares of common stock that may be issued upon exercise or vesting of outstanding equity incentive awards and warrants, and proportionate increases were made to the exercise price or share-based performance criteria, if any, applicable to such awards and warrants.

Redemption of Series F Preferred Stock

On April 17, 2023, the Company convened a special meeting of stockholders, which was adjourned due to the lack of a quorum and reconvened on April 19, 2023 (the “Special Meeting”), at which the Company’s stockholders approved a proposal to amend the Company’s certificate of incorporation to effect a reverse stock split of the Company’s common stock at a ratio in the range of 1-for-2 to 1-for-25, with such ratio to be determined by the Company’s Board of Directors (the “Reverse Split Proposal”). All shares of Series F Preferred Stock that were not present in person or by proxy at the Special Meeting as of immediately prior to the opening of the polls (the “Initial Redemption Time”) were automatically redeemed (the “Initial Redemption”). All outstanding shares of Series F Preferred Stock that were not redeemed pursuant to the Initial Redemption were redeemed automatically upon the approval by the Company’s stockholders of the Reverse Split Proposal (the “Subsequent Redemption” and, together with the Initial Redemption, the “Redemption”). Both the Initial Redemption and the Subsequent Redemption occurred on April 19, 2023. As a result, no shares of Series F Preferred Stock remain outstanding.

At The Market Offering

On May 3, 2024, the Company entered into an ATM Sales Agreement (the “Sales Agreement”) with H.C. Wainwright & Co., LLC (“Wainwright”), to sell shares of the Company’s common stock, par value $0.01 per share (the “Shares”), having an aggregate sales price of up to $3,696,000, from time to time, through an “at the market offering” program pursuant to which Wainwright will act as sales agent. Subject to the terms and conditions of the Sales Agreement, Wainwright is permitted to sell the Shares by methods deemed to be an “at the market offering” as defined in Rule 415(a)(4) promulgated under the Securities Act of 1933, as amended. The Sales Agreement provides that Wainwright will be entitled to compensation for its services of 3.0% of the gross sales price of all shares sold through Wainwright under the Sales Agreement. As of June 30, 2024, the Company has sold 1,607,100 shares of common stock at an average price of approximately $2.30 per share, resulting in aggregate gross proceeds of approximately $3,696,000.

Equity Incentive Plan

The Company’s Amended and Restated 2012 Stock Incentive Plan (the “2012 Plan”) allows for the issuance of incentive and non-qualified stock options, stock appreciation rights, stock awards, restricted stock, restricted stock units (“RSUs”) and performance awards to employees, directors, and consultants of the Company, where permitted under the plan. The exercise price for each stock option is determined by the market price on the date of issuance. Vesting requirements are determined by the Board of Directors when granted and currently range from immediate to three years. Options outstanding under this plan have a contractual life of ten years.

ASC 718, Compensation – Stock Compensation (“ASC 718”), requires that a company that issues equity as compensation record compensation expense that corresponds to the estimated cost of those equity grants. ASC 718 requires companies to estimate the fair value of stock-based payment awards on the date of grant using an option-pricing model or other acceptable means.

Valuation and Accounting for Stock Options and Warrants

The Company determines the grant date fair value of options and warrants using a Black-Scholes option valuation model based upon assumptions regarding risk-free interest rate, expected dividend rate, volatility, and estimated term.

During the three and six months ended June 30, 2024, there were no options or warrants granted. The fair value of each stock option grant was estimated on the grant date using the Black-Scholes option valuation model with the following assumptions:

	Six Months Ended June 30,
	2024		2023
	Stock Options
Expected dividend yield		-		0.0%
Expected stock price volatility		-		90.8% –91.6%

Stock-based compensation expense, net of forfeitures, recognized for the six months ended June 30, 2024, and 2023, was $1,040 and $15,159, respectively. Stock-based compensation expense is recorded within each of the captions comprising Operating expenses. The Company has $182 of unrecognized compensation expense related to unvested stock options that is expected to be recognized over the next 10 months.

NOTE 12 – SEGMENTS

The Company has determined its operating segments in accordance with ASC 280 – Segment Reporting. Factors used to determine the Company’s reportable segments include the availability of separate financial statements, the existence of locally based leadership across geographic regions, the economic factors affecting each segment, and the evaluation of operating results at the segment level. The Chief Operating Decision Maker (“CODM”) allocates the Company’s resources for each of the operating segments and evaluates their relative performance. Each operating segment listed below has separate financial statements and locally based leadership that are evaluated based on the results of their respective segments. It should be noted that the operating segments below have different products and services. The financial information is consolidated and evaluated regularly by the CODM in assessing performance and allocating resources.

The Company has three reportable segments, which have been delineated by location and business area:

●

Birmingham segment: provides contract services and research focused on solubility improvements, stability studies, and protein production.

NOTE 13 – SUBSEQUENT EVENTS

Warrant Inducement Transaction

On July 25, 2024, the Company entered into definitive agreements with certain of its existing warrant holders for the exercise of warrants to purchase an aggregate of 958,117 shares of its common stock having a current exercise price of $14.00 originally issued in February 2021, June 2021 and May 2022, at a reduced exercise price of $1.32 per share. The gross proceeds to the Company from the exercise of the existing warrants were approximately $1.26 million, prior to deducting placement agent fees and transaction expenses payable by the Company.

In consideration for the immediate cash exercise of the warrants, the Company concurrently issued to the warrant holders new unregistered Series A warrants to purchase up to 958,117 shares of common stock (the “Series A Warrants”) and new Series B warrants to purchase up to 958,117 shares of common stock (the “Series B Warrants”). The Series A Warrants and the Series B Warrants have an exercise price of $1.07 per share and are exercisable immediately upon issuance. The Series A Warrants have a term equal to five years from the date of issuance, and the Series B Warrants have a term equal to 18 months from the date of issuance.

The transactions described above closed on July 26, 2024. Wainwright acted as the exclusive placement agent for the above-mentioned transactions. The Company paid Wainwright as consideration (i) an aggregate cash fee equal to 7.0% of the gross proceeds from the exercise of the existing warrants, (ii) a management fee equal to 1.0% of the aggregate gross proceeds from the exercise of the existing warrants, (iii) $35,000 for expenses, and (iv) $15,950 for clearing fees. Additionally, the Company issued to Wainwright (or its designees) as compensation, warrants to purchase up to 67,068 shares of common stock of the Company (equal to 7.0% of the aggregate number of existing warrants exercised in the offering) (the “Placement Agent Warrants”). The Placement Agent Warrants have a term of five years from the closing of the offering and an exercise price of $1.65 per share.

Strategic Cost Savings Initiative

On July 25, 2024, the Company’s Board of Directors approved a plan to implement a strategic cost savings initiative, primarily related to the consolidation of the operations of the Company’s Birmingham laboratory into its Pittsburgh laboratory. The Company began implementing the cost savings initiative in August 2024 and continues to review its progress and effectiveness, including the impact of the changes on the Company’s operating segments and the full financial effect on our consolidated financial statements.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read together with our unaudited condensed consolidated financial statements and related notes thereto set forth in this Quarterly Report on Form 10-Q as well as our Annual Report on Form 10-K for the year ended December 31, 2023.

This Quarterly Report on Form 10-Q contains “forward-looking statements” that are management’s present expectations of future events. Actual results could differ materially and adversely from those anticipated in such forward-looking statements as a result of certain factors, including but not limited to those set forth below and elsewhere in this report, many of which are beyond our control. Important factors that may cause actual results to differ from forward-looking statements include:

●	Our ability to continue operating beyond twelve months without additional financing;

●	Continued negative operating cash flows;

●	Our capital needs to accomplish our goals, including any further financing, which may be highly dilutive and may include onerous terms;

●	Risks related to recent and future acquisitions, including risks related to the benefits and costs of acquisition;

Overview

We are a knowledge and science-driven company that applies artificial intelligence (“AI”) to support the discovery and development of optimal cancer therapies, which can ultimately lead to more effective treatments and improved patient outcomes. We use AI and a proprietary biobank of 150,000+ tumor samples, categorized by tumor type, to provide actionable insights about drug compounds to improve the drug discovery process and increase the probability of drug compound success. We offer a suite of solutions for oncology drug development from early discovery to clinical trials.

Our mission is to change the landscape of oncology drug discovery and enable the development of more effective therapies for the treatment of cancer. By harnessing the power of machine learning and scientific rigor, we believe that we can improve the probability of success of advancing pharmaceutical and biological drug candidates with a higher degree of confidence.

We operate in three business areas. In our first area, we provide optimized, high-confidence drug-response predictions through the application of AI using our proprietary biobank of tumor samples to enable a more informed selection of drug/tumor combinations and increase the probability of success during development. We also create and develop tumor-specific 3D cell culture models mimicking the physiological environment of human tissue enabling better-informed decision-making during development. In our second business area, we provide services and research using a proprietary self-contained and automated system that conducts high-throughput, self-interaction chromatography screens using additives and excipients commonly included in protein formulations resulting in soluble and physically stable formulations of biologics. Our third business area produces the United States Food and Drug Administration (“FDA”)-cleared STREAMWAY® System and associated products for automated medical fluid waste management and patient-to-drain medical fluid disposal.

We have three reportable segments, which have been delineated by location and business area:

●

Birmingham segment: provides contract services and research focused on solubility improvements, stability studies, and protein production.

●

Eagan segment: produces the FDA-cleared STREAMWAY System and associated products for automated medical fluid waste management and patient-to-drain medical fluid disposal.

On July 25, 2024, our board of directors approved a plan to implement a strategic cost savings initiative, primarily related to the consolidation of the operations of our Birmingham laboratory into our Pittsburgh laboratory. We began implementing the cost savings initiative in August 2024 and continue to review its progress and effectiveness, including the impact of the changes on our operating segments as described immediately above. In particular, we anticipate that our three segments will be reduced to two in future reporting periods with the closure of our Birmingham laboratory. The initiative is expected to reduce the Company’s run rate for cash used in operating activities by approximately 20% annually when fully implemented in Q4 2024.

Capital Requirements

Since inception, we have been unprofitable. We incurred net losses of $7,400,104 and $7,345,170 for the six months ended June 30, 2024, and 2023, respectively. As of June 30, 2024, and December 31, 2023, we had an accumulated deficit of $175,161,987 and $167,761,883, respectively.

We have never generated sufficient revenues to fund our capital requirements. We have funded our operations through a variety of debt and equity instruments. Since 2017, we have diversified our business by investing in ventures, including making significant loans and investments in early-stage companies. These activities led to the acquisition of Helomics Corporation in April 2019, two transactions to acquire the assets of three businesses in 2020, and the acquisition of zPREDICTA Inc. in November 2021, each of which have accelerated our capital needs. See “Liquidity and Capital Resources – Liquidity and Plan of Financing; Going Concern” and “Liquidity and Capital Resources – Financing Transactions” below.

Our future cash requirements and the adequacy of available funds depend on our ability to generate revenues from our oncology businesses located in Pittsburgh and Birmingham; our ability to continue to sell our Skyline Medical products and services and to reach profitability in all our businesses; and the availability of future financing to fulfill our business plans. See “Liquidity and Capital Resources – Liquidity and Plan of Financing; Going Concern” below.

Our limited history of operations, especially in our drug discovery business, and our change in the emphasis of our business, starting in 2017, makes prediction of future operating results difficult. We believe that period-to-period comparisons of our operating results should not be relied on as predictive of our future results.

Revenue. We recorded revenue of $278,722 and $490,110 in the three months ended June 30, 2024, and 2023, respectively. Revenue in the three months ended June 30, 2024, and 2023, was primarily derived from the Eagan operating segment. The decrease in revenue from the comparative period was primarily due to a change in sales mix with decreased sales of STREAMWAY systems in the three months ended June 30, 2024.

We recorded revenue of $698,368 and $730,005 in the six months ended June 30, 2024, and 2023, respectively. Revenue in the six months ended June 30, 2024, was primarily derived from the Eagan operating segment. The decrease in revenue from the comparative period was primarily due to a change in sales mix with decreased sales related to biologics in our Birmingham operating segment during the six months ended June 30, 2024.

Cost of sales. Cost of sales was $152,968 and $159,761 in the three months ended June 30, 2024, and 2023, respectively. The gross profit margin was approximately 45% and 67% in the three months ended June 30, 2024, and 2023, respectively. The decline in gross profit margin for the three months ended June 30, 2024, was primarily due to increased labor costs and a change in sales mix with decreased sales of STREAMWAY systems.

Cost of sales was $340,383 and $279,900 in the six months ended June 30, 2024, and 2023, respectively. The gross profit margin was approximately 51% and 62% in the six months ended June 30, 2024, and 2023, respectively. The decline in gross profit margin for the six months ended June 30, 2024, was primarily due to increased labor costs.

General and administrative expense. General and administrative (“G&A”) expense primarily consists of management salaries, professional fees, consulting fees, administrative fees, and general office expenses. G&A expense decreased by $567,338 to $2,137,189 in the three months ended June 30, 2024, compared to $2,704,527 in the comparable period in 2023. The decrease was primarily due to decreased employee compensation and decreased investor relations costs, offset by increased consultant fees.

G&A expense decreased by $276,246 to $4,764,265 in the six months ended June 30, 2024, compared to $5,040,511 in the comparable period in 2023. The decrease was primarily due to decreased employee compensation and decreased investor relations costs, offset by increased audit fees and consultant fees.

Operations expense. Operations expense primarily consists of expenses related to product development and prototyping and testing. Operations expense decreased by $99,651 to $893,391 in the three months ended June 30, 2024 compared to $993,042 in the comparable period in 2023. The decrease was primarily due to decreased cloud computing expenses related to our Pittsburgh operating segment.

Operations expense increased by $124,024 to $1,995,584 in the six months ended June 30, 2024, compared to $1,871,560 in the comparable period in 2023. The increase was primarily due to higher employee compensation.

Sales and marketing expense. Sales and marketing expenses consist of expenses required to market and sell our products including staff-related expenses for individuals performing this work. Sales and marketing expense decreased by $144,682 to $284,421 in the three months ended June 30, 2024, compared to $429,103 in the comparable period in 2023. The decrease was primarily due to lower employee compensation including sales commissions.

Sales and marketing expense increased by $224,815 to $1,024,155 in the six months ended June 30, 2024, compared to $799,340 in the comparable period in 2023. The increase was primarily due to severance related to a former executive.

Loss on impairment of property and equipment. We recorded no losses on impairment of property and equipment during the three and six months ended June 30, 2024. We recorded a loss on impairment of property and equipment of $162,905 during the three and six months ended June 30, 2023. We prepared an undiscounted cash flow for our Birmingham asset group as of June 30, 2023, to evaluate long-lived assets, then completed a fair value assessment which resulted in the impairment and allocated the impairment to the assets of the affected asset group. Please see Note 5 – Property and Equipment to our unaudited condensed consolidated financial statements for further information.

Other income. We earned other income of $9,461 during the three months ended June 30, 2024, compared to $28,552 in the comparable period in 2023. We earned other income of $28,118 during the six months ended June 30, 2024, compared to $70,780 in the comparable period in 2023. Other income in all periods primarily consisted of interest income.

Other expense. We incurred other expense of $1,834 during the three months ended June 30, 2024, compared to no other expense in the comparable period in 2023. We incurred other expense of $3,571 during the six months ended June 30, 2024, compared to no other expense in the comparable period in 2023. Other expense in 2024 consisted primarily of interest expense.

Gain on derivative instruments. We recorded a gain of $359 in the three months ended June 30, 2024, compared to $7,308 in the comparable period in 2023. We recorded a gain of $1,368 in the six months ended June 30, 2024, compared to $8,261 in the comparable period in 2023. These gains related to the change in fair value of the derivative.

Liquidity and Capital Resources

Cash Flows

Net cash used in operating activities was $6,634,072 and $7,002,033 for the six months ended June 30, 2024, and 2023, respectively. Cash used in operating activities decreased in the 2024 period primarily because of changes in working capital.

Net cash used in investing activities was $9,510 and $305,745 for the six months ended June 30, 2024, and 2023, respectively. Cash used in investing activities decreased in the 2024 period primarily due to a decrease in fixed asset purchases during the six months ended June 30, 2024, as compared to the same period in 2023.

Net cash provided by financing activities was $3,246,692 and $0 for the six months ended June 30, 2024, and 2023, respectively. The cash provided in the six months ended June 30, 2024, was primarily due to proceeds from the issuance of common stock pursuant to the ATM offering completed in May 2024.

Liquidity and Plan of Financing; Going Concern

We have incurred significant and recurring losses from operations for the past several years and, as of June 30, 2024, had an accumulated deficit of $175,161,987. We had cash and cash equivalents of $5,331,770 as of June 30, 2024, and need to raise significant additional capital to meet our operating needs. We had short-term obligations of $4,618,511 and long-term operating lease obligations of $1,860,983 as of June 30, 2024. We do not expect to generate sufficient operating revenue to sustain our operations in the near term. During the six months ended June 30, 2024, we incurred negative cash flows from operations of $6,634,072. Although we have attempted to improve our cash flows from operations by bolstering revenues and continue to seek ways to generate revenue through business development activities, there is no guarantee that we will be able to improve our cash flows from operations sufficiently or achieve profitability in the near term. As a result of these conditions, substantial doubt exists about our ability to continue as a going concern within one year after the date our unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q are issued.

We are evaluating alternatives to obtain the required additional funding to maintain future operations. These alternatives may include, but are not limited to, equity financing, issuing debt, entering into other financing arrangements, or monetizing operating businesses or assets. These possibilities, to the extent available, may be on terms that result in significant dilution to our existing stockholders or that result in our existing stockholders losing part or all of their investment. Despite these potential sources of funding, we may be unable to access financing or obtain additional liquidity when needed or under acceptable terms, if at all. If such financing or adequate funds from operations are not available, we would be forced to limit our business activities and we could default on existing payment obligations, which would have a material adverse effect on our financial condition and results of operations, and may ultimately be required to cease our operations and liquidate our business. Our condensed consolidated financial statements as of and for the three and six months ended June 30, 2024, included in this Quarterly Report on Form 10-Q, have been prepared assuming we will continue as a going concern and do not include any adjustments that might result from the outcome of this uncertainty.

Financing Transactions

We have primarily funded our operations through a combination of debt and equity instruments including short-term borrowings, and a variety of debt and equity offerings. We have no off-balance sheet transactions.

There were no financing transactions during the six months ended June 30, 2023.

Accounting Standards and Recent Accounting Developments

See Note 1 - Summary of Significant Accounting Policies to the unaudited condensed consolidated financial statements of this Quarterly Report on Form 10-Q for a discussion of recent accounting developments.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Not required.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act), defines the term “disclosure controls and procedures” as those controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Management, with the participation of our Chief Executive Officer and Interim Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as of June 30, 2024. Based on that evaluation, our Chief Executive Officer and Interim Chief Financial Officer concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were effective as of June 30, 2024.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) during the six months ended June 30, 2024, that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

In the ordinary course of business, we may periodically become subject to legal proceedings and claims arising in connection with ongoing business activities from time to time. The results of litigation and claims cannot be predicted with certainty, and unfavorable resolutions are possible and could materially affect our results of operations, cash flows or financial position. In addition, regardless of the outcome, litigation could have an adverse impact on us because of defense costs, diversion of management attention and resources and other factors.

Based on information readily available, as of the end of the period covered by this Quarterly Report on Form 10-Q, there are no pending legal proceedings that, in the opinion of management, are likely to result in a material adverse effect on our financial position, results of operations or cash flows.

ITEM 1A. RISK FACTORS

As of the date of this Quarterly Report on Form 10-Q, there have been no material changes to our risk factors from those disclosed under “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on March 28, 2024.

In addition to the information set forth in this Quarterly Report on Form 10-Q, the reader should carefully consider the risks included in Item 1A of Part I of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, before making an investment decision. Our business could be harmed by any of these risks. The trading price of our common stock could decline due to any of these risks, and you may lose all or part of your investment.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

During the six months ended June 30, 2024, there were no sales of our securities that were not registered under the Securities Act.

ITEM 3. DEFAULTS UPON SENIOR SECURITIES

None.

ITEM 4. MINE SAFETY DISCLOSURES

Not applicable.

Significant Accounting Policies (Policies)	Jun. 30, 2024
Accounting Policies [Abstract]
Nature Of Operations and Going Concern Policy [Policy Text Block]	Going Concern These condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) assuming the Company will continue as a going concern. The going concern assumption contemplates the realization of assets and satisfaction of liabilities in the normal course of business. However, substantial doubt about the Company’s ability to continue as a going concern exists. The Company has incurred significant and recurring losses from operations for the past several years and, as of June 30, 2024, had an accumulated deficit of $175,161,987. The Company had cash and cash equivalents of $5,331,770 as of June 30, 2024, and needs to raise significant additional capital to meet its operating needs. The Company had short-term obligations of $4,618,511 and long-term operating lease obligations of $1,860,983 as of June 30, 2024. The Company does not expect to generate sufficient operating revenue to sustain its operations in the near term. During the six months ended June 30, 2024, the Company incurred negative cash flows from operations of $6,634,072. Although the Company has attempted to improve its cash flows from operations by bolstering revenues and continues to seek ways to generate revenue through business development activities, there is no guarantee that the Company will be able to improve its cash flows from operations sufficiently or achieve profitability in the near term. As a result of these conditions, substantial doubt exists about the Company’s ability to continue as a going concern within one year after the date these condensed consolidated financial statements are issued. The Company is evaluating alternatives to obtain the required additional funding to maintain future operations. These alternatives may include, but are not limited to, equity financing, issuing debt, entering into other financing arrangements, or monetizing operating businesses or assets. These possibilities, to the extent available, may be on terms that result in significant dilution to the Company’s existing stockholders or that result in the Company’s existing stockholders losing part or all of their investment. Despite these potential sources of funding, the Company may be unable to access financing or obtain additional liquidity when needed or under acceptable terms, if at all. If such financing or adequate funds from operations are not available, the Company would be forced to limit its business activities and the Company could default on existing payment obligations, which would have a material adverse effect on its financial condition and results of operations, and the Company may ultimately be required to cease its operations and liquidate its business. The Company’s condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern and do not include any adjustment relating to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should the Company be unable to continue in existence.
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The Company has prepared the condensed consolidated financial statements and related unaudited financial information in the notes in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim condensed consolidated financial statements. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These interim condensed consolidated financial statements reflect all adjustments consisting of normal recurring adjustments, which in the opinion of management, are necessary to present fairly the Company’s position, the results of its operations, and its cash flows for the interim periods. These interim condensed consolidated financial statements reflect all intercompany eliminations. These interim condensed consolidated financial statements should be read in conjunction with the annual consolidated financial statements and the notes thereto contained in the Annual Report on Form 10-K filed with the SEC on March 28, 2024. The nature of the Company’s business is such that the results of any interim period may not be indicative of the results to be expected for the entire year.
Use of Estimates, Policy [Policy Text Block]	Accounting Policies and 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 and expenses and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and during the reporting period. Actual results could materially differ from those estimates. Estimates are used in the following areas, among others: variable consideration associated with revenue recognition, stock-based compensation expense, fair value of long-lived assets for impairment analyses, the valuation allowance included in the deferred income tax calculation, accrued expenses, and fair value of derivative liabilities. Note 1 to the annual consolidated financial statements contained in the Annual Report on Form 10-K filed with the SEC on March 28, 2024, describes the significant accounting policies and estimates used in preparation of the consolidated financial statements. There have been no material changes in the Company’s significant accounting policies during the six months ended June 30, 2024.
Consolidation, Policy [Policy Text Block]	Principles of Consolidation The Company had two wholly owned subsidiaries, Helomics Corporation and Skyline Medical, Inc. (“Skyline Medical”), as of June 30, 2024, and December 31, 2023, and for the three and six months ended June 30, 2024, and 2023. The condensed consolidated financial statements include the accounts of the Company and these wholly owned subsidiaries after elimination of intercompany transactions and balances as of June 30, 2024, and December 31, 2023, and for the three and six months ended June 30, 2024, and 2023.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentration of Credit Risk Financial instruments that subject the Company to credit risk primarily consist of cash and cash equivalents and accounts receivable. The Company maintains its cash and cash equivalent balances with high quality financial institutions and, consequently, the Company believes that such funds are subject to minimal credit risk. The Company is exposed to credit risk in the event of default by the financial institutions to the extent amounts recorded on the condensed consolidated balance sheets are in excess of insured limits. The Company has not experienced any credit losses in such accounts and does not believe it is exposed to any significant credit risk on these funds. As of June 30, 2024, accounts receivable from a single customer represented 11% of the Company’s total accounts receivable. As of December 31, 2023, accounts receivable from a single customer represented 16% of the Company’s total accounts receivable.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements The Company considers the applicability and impact of all Accounting Standards Updates (“ASUs”) issued by the Financial Accounting Standards Board (the “FASB”). Recently issued ASUs not listed below either were assessed and determined to be not applicable or are currently expected to have no impact on the condensed consolidated financial statements of the Company. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This ASU updates reportable segment disclosures by expanding the frequency and extent of segment disclosures. This ASU is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The ASU requires the retrospective adoption method. Management is currently evaluating this ASU to determine its impact on the Company’s disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU requires more detailed income tax disclosures. The guidance requires entities to disclose disaggregated information about their effective tax rate reconciliation as well as expanded information on income taxes paid by jurisdiction. The disclosure requirements will be applied on a prospective basis, with the option to apply them retrospectively. This ASU is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. Management is currently evaluating this ASU to determine its impact on the Company’s disclosures.
