Note 1 - Organization and Business

ProPhase Labs, Inc. (“ProPhase”, “we”, “us”, “our” or the “Company”) is a diversified company that offers a range of services including genomics testing, diagnostic testing and contract manufacturing. We are also focused on licensing, developing and commercializing novel drugs, dietary supplements, compounds and diagnostics.

Until late fiscal year 2020, the Company was engaged primarily in the research, development, manufacture, distribution, marketing and sale of over-the-counter ("OTC") consumer healthcare products and dietary supplements in the United States.

In October 2020, the Company completed the acquisition of all of the issued and outstanding shares of capital stock of Confucius Plaza Medical Laboratory Corp. (“CPM”), which owned a 4,000 square foot Clinical Laboratory Improvement Amendments (“CLIA”) accredited laboratory located in Old Bridge, New Jersey for approximately $2.5 million, and began offering COVID-19 diagnostic tests through our wholly-owned subsidiary, ProPhase Diagnostics, Inc. ("ProPhase Diagnostics") in December 2020. Also in December 2020, we expanded our diagnostic service business with the build-out of a second, larger CLIA accredited laboratory in Garden City, New York. Operations at this second facility commenced in January 2021. We offered a broad array of COVID-19 related clinical diagnostic and testing services including polymerase chain reaction testing for COVID-19 and Influenza A and B through ProPhase Diagnostics, as well as rapid antigen and antibody/immunity testing for COVID-19. Due to the significant decrease in demand and reimbursement rate for our diagnostic testing service, we have reduced the amount of diagnostic testing services that we provide since the second half of 2023. Nonetheless we are prepared to provide an increased volume of our diagnostic testing service if diagnostic testing is required due to a new COVID-19 outbreak. We have continued to ship COVID-19 antigen kits under an existing contract to our customer. In addition, in order to maintain licenses in certain states in which we operate, we currently perform several diagnostic tests each quarter to maintain our certified lab status, and we currently plan to do so for the foreseeable future.

In August 2021, the Company acquired Nebula Genomics, Inc. (“Nebula”), a privately owned personal genomics company, through our wholly-owned subsidiary, ProPhase Precision Medicine Inc. Nebula focuses on genomics sequencing technologies, a comprehensive method for analyzing entire genomes, including the genes and chromosomes in deoxyribonucleic acidDNA. The data obtained from genomic sequencing can be used to help identify inherited disorders and tendencies, help predict disease risk, help identify expected drug response, and characterize genetic mutations, including those that drive cancer progression.

The Company's wholly owned subsidiary, ProPhase BioPharma, Inc. (“PBIO”), was formed in June 2022, for the licensing, development and commercialization of novel drugs, dietary supplements and compounds. Licensed compounds currently include Equivir (a OTC, dietary supplement candidate) and Equivir G (prescription drug candidate), two broad-based anti-virals, and Linebacker LB-1 and LB-2, two small molecule proviral integration site for moloney murine leukemia virus kinase inhibitors. The Company also own the exclusive rights to the BE-Smart Esophageal Pre-Cancer Diagnostic Screening test and related intellectual property assets.

In connection with the activities of PBIO, in January 2023, the Company acquired exclusive rights to BE-Smart Esophageal Pre-Cancer Diagnostic Screening test and related intellectual property assets. The BE-Smart test is focused on the early detection of esophageal cancer, and is intended to provide health care providers and patients with data to help determine treatment options. The development of these novel drugs and compounds is highly dependent on how each performs during the testing and development stage, the demand for these product and services once entered into the marketplace, our marketing and service capabilities and our ability to comply with applicable regulatory requirements.

The Company's wholly-owned subsidiary, Pharmaloz Manufacturing, Inc. (“PMI”), is a full-service contract manufacturer and private label developer of a broad range of non-GMO, organic and natural-based cough drops and lozenges and OTC drug and dietary supplement products.

The Company also develops and markets dietary supplements under the TK Supplements® brand. The TK Supplements® product line includes Legendz XL®, a male sexual enhancement and Triple Edge XL®, an energy and stamina booster.

The Company's wholly owned subsidiary, Pharmaloz Real Estate Holdings, Inc. (“PREH”), was formed in November 2023, for the purpose to receive additional investment to expand its current facility. There were no operations for PREH as of March 31, 2024.

The Company continues to actively pursue acquisition opportunities for other companies, technologies and products within and outside the consumer products industry.

Note 2 - Summary of Significant Accounting Policies

Basis of Presentation

The unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles accepted in the United States of America (“GAAP”) for interim financial statements and the rules of the Securities and Exchange Commission (“SEC”) applicable to interim financial statements. Certain information or footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. The accompanying unaudited condensed consolidated financial statements have been prepared by management without audit and should be read in conjunction with our audited consolidated financial statements, including the notes thereto, appearing in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023. In the opinion of management, all adjustments necessary for a fair presentation of the consolidated financial position, consolidated results of operations and other comprehensive loss and consolidated cash flows, for the periods indicated, have been made. The results of operations for the three months ended March 31, 2024 are not necessarily indicative of operating results that may be achieved over the course of the full year.

Use of Estimates

The preparation of condensed consolidated financial statements and the accompanying notes thereto, in conformity with GAAP, requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and reported amounts of revenues and expenses during the respective reporting periods. Examples include revenue recognition and the impact of the variable consideration of diagnostic test reimbursement rates, the allowance for credit losses and billing errors, allowances, slow moving and/or dated inventory and associated provisions, the potential impairment of long-lived assets, stock based compensation valuations, income tax asset valuations and assumptions related to accrued advertising.

Our estimates and assumptions are based on historical experience, current trends and other factors that management believes to be relevant at the time the condensed consolidated financial statements are prepared. Management reviews the accounting policies, assumptions, estimates and judgments on a quarterly basis. Actual results could differ from those estimates.

Fair Value of Financial Instruments

We measure assets and liabilities at fair value based on expected exit price as defined by the authoritative guidance on fair value measurements, which represents the amount that would be received on the sale date of an asset or paid to transfer a liability, as the case may be, in an orderly transaction between market participants. As such, fair value may be based on assumptions that market participants would use in pricing an asset or liability. The authoritative guidance on fair value measurements establishes a consistent framework for measuring fair value on either a recurring or nonrecurring basis whereby inputs, used in valuation techniques, are assigned a hierarchical level.

The following are the hierarchical levels of inputs to measure fair value:

•Level 1: Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

•Level 2: Inputs reflect quoted prices for identical assets or liabilities in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs other than quoted prices that are observable for the assets

ProPhase Labs, Inc. and Subsidiaries

Notes to Condensed Consolidated Financial Statements

(unaudited)

or liabilities; or inputs that are derived principally from or corroborated by observable market data by correlation or other means.

•Level 3: Unobservable inputs reflecting the Company’s assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available.

The carrying amounts of our financial assets and liabilities, such as cash, accounts receivable, accounts payable, and unsecured note payable, approximate their fair values because of the short-term nature of these instruments.

We account for our marketable securities at fair value, with the net unrealized gains or losses of marketable debt securities reported as a component of accumulated other comprehensive income or loss and marketable equity securities change in fair value reported on the condensed consolidated statements of operation and comprehensive income (loss). The components of marketable securities are as follows (in thousands):


	As of March 31, 2024
	Level 1		Level 2		Level 3		Total
Corporate obligations	58		—		—		58
	$	58	$	—	$	—	$	58


	As of December 31, 2023
	Level 1		Level 2		Level 3		Total
Corporate stock	$	3,127	$	—	$	—	$	3,127
	$	3,127	$	—	$	—	$	3,127

There were no transfers of marketable debt securities between Levels 1, 2 or 3 for the three months ended March 31, 2024 and 2023.

Goodwill

Goodwill represents the excess of the fair value of the consideration transferred over the fair value of the underlying identifiable assets and liabilities acquired in a business combination. Goodwill and intangible assets deemed to have an indefinite life are not amortized, but instead are assessed for impairment annually. Additionally, if an event or change in circumstances occurs that would more likely than not reduce the fair value of the reporting unit below its carrying value, we would evaluate goodwill at that time.

During the three months ended March 31, 2023, the Company received $0.5 million in connection with terms from an escrow agreement from the purchase of Nebula. The receipt of this escrow payment reduced the excess consideration paid for Nebula and was recorded as a reduction of the Goodwill at the time of receipt.

Revenue Recognition and Accounts Receivable

The Company recognizes revenues in accordance with Financial Accounting Standards Board (“FASB”)’s Accounting Standards Codification ("ASC") 606, Revenues from Contracts with Customers. The Company recognizes revenue that represents the transfer of promised goods or services to customers at an amount that reflects the consideration that is expected to be received in exchange for those goods or services. The Company recognizes revenue when performance obligations with our customers have been satisfied. At contract inception, we evaluate the contract to determine if revenue should be recognized using the following five steps: (1) identify the contract with the customer; (2) identify the performance obligations; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations; and (5) recognize revenue when (or as) the entity satisfies a performance obligation.

The Company carries its accounts receivable at cost less an allowance for credit losses. Allowances for credit losses are based upon the Company’s judgment regarding collectability. On a periodic basis, the Company evaluates its receivables and establish an allowance for credit losses, based on a history of past write-offs, collections, current credit conditions or generally accepted future trends in the industry and/or local economy. Accounts are written off as

(unaudited)

uncollectible at the time we determine that collections are unlikely. The reserve is not intended to address return activity or disputed balances with ongoing customers, as this should be addressed in a reserve for credit memos with a corresponding charge to revenue.

Income Taxes

The Company recognizes deferred tax liabilities and assets based on the differences between the financial statement carrying amounts and the tax bases of assets and liabilities, using enacted tax rates in effect in the years the differences are expected to reverse.

The provision for, or benefit from, income taxes includes deferred taxes resulting from the temporary differences in income for financial and tax purposes using the liability method. Future realization of deferred income tax assets requires sufficient taxable income within the carryback, carryforward period available under tax law. We evaluate, on a quarterly basis whether, based on all available evidence, it is probable that the deferred income tax assets are realizable. Valuation allowances are established when it is more likely than not that the tax benefit of the deferred tax asset will not be realized. The evaluation, as prescribed by ASC 740-10, “Income Taxes,” includes the consideration of all available evidence, both positive and negative, regarding historical operating results including recent years with reported losses, the estimated timing of future reversals of existing taxable temporary differences, estimated future taxable income exclusive of reversing temporary differences and carryforwards, and potential tax planning strategies which may be employed to prevent an operating loss or tax credit carryforward from expiring unused.

The Company accounts for uncertainties in income taxes under the provisions of FASB ASC 740-10-05 (the “Subtopic”). The Subtopic clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. The Subtopic prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Subtopic provides guidance on the de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.

Recently Issued Accounting Standards, Not Yet Adopted

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires an enhanced disclosure of significant segment expenses on an annual and interim basis. This guidance will be effective for the annual periods beginning the year ended December 31, 2024, and for interim periods beginning January 1, 2025. Early adoption is permitted. Upon adoption, the guidance should be applied retrospectively to all prior periods presented in the financial statements. The Company does not expect the adoption of this guidance to have a material impact on its condensed consolidated financial statements.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which improves the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the effective tax rate reconciliation and income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures. This guidance will be effective for the annual periods beginning the year ended December 31, 2025. Early adoption is permitted. Upon adoption, the guidance can be applied prospectively or retrospectively. The Company does not expect the adoption of this guidance to have a material impact on its condensed consolidated financial statements.

Recently Issued Accounting Standards, Adopted

In March 2024, the FASB issued ASU No. 2024-01, “Compensation-Stock Compensation (Topic 718): Scope Applications of Profits Interests and Similar Awards” ("ASU 2024-01"). ASU 2024-01 adds an example to Topic 718 which illustrates how to apply the scope guidance to determine whether profits interests and similar awards should be accounted for as share-based payment arrangements under Topic 718 or under other topics of GAAP. ASU 2024-01 is effective for annual periods beginning after December 15, 2024, although early adoption is permitted. Upon adoption, ASU 2024-01 is not expected to have an impact on the Company’s condensed consolidated financial statements.

(“Stella”) and Stella DX, LLC (“Stella DX” and, together with Stella, the “Stella Sellers”), pursuant to which, on January 3, 2023, the Company purchased all of the assets, rights and interests of the Stella Sellers and their affiliates pertaining to the Stella Sellers’ BE-Smart Esophageal Pre-Cancer Diagnostic Screening Test and certain clinical assets, including all intellectual property rights (the “Stella Purchased Assets”).

As consideration for the Stella Purchased Assets, at closing, the Company (i) paid to the Stella Sellers $3.5 million in cash, minus (a) the Secured Note Amount of $0.5 million, (b) the Liability Payoff Amount of $1.6 million and (c) the Promissory Note Payoff Amount of $0.4 million, and (ii) issued to Stella DX 100,000 shares of common stock, par value $0.0005 per share, of the Company at a value of $10.00 per share. Total consideration paid was $4.6 million. The Secured Note Amount of $0.5 million and the Promissory Note Payoff of $0.4 million were paid in 2022. The balance of the consideration was paid at closing on January 3, 2023.

In addition to the consideration paid at closing, the Company will issue shares of common stock valued at $2.0 million to the Stella Sellers upon a Commercialization Event (as defined in the Stella Purchase Agreement). Such stock was recorded at closing as a non-current liability at its fair value of $2.0 million. Also, the Company is required to pay to the Stella Sellers for each of the seven calendar years during the seven year period commencing on the first day of the calendar year following the date of the Commercialization Event, a non-refundable, non-creditable royalty of 5% of the Adjusted Gross Margin (as defined in the Stella Purchase Agreement) for such annual period.

The asset purchase does not qualify as a business combination under ASC 805, Business Combinations, and has therefore been accounted for as an asset acquisition. In connection with the Stella Purchased Assets, the Company incurred $0.2 million in transaction costs, which were capitalized into the purchase price of the Stella Purchased Assets. The total purchase price for the Stella Purchased Assets was $6.8 million, which was allocated to the proprietary technology intangible asset acquired. The Company is amortizing the acquired intangible asset on a straight-line basis over its estimated useful life of five years.

2024 Future Receipts Financing

On February 14, 2024 (the “Commencement Date”), the Company entered into an agreement of sale of future receipts (“Future Receipts Financing Agreement”) with Libertas Funding, LLC (“Libertas”) by which Libertas purchases from the Company, its future accounts and contract rights arising from the sale of goods or rendition of services to the Company’s customers. The purchase price was approximate $2.5 million, which was paid to the Company on February 16, 2024, net of $50,000 origination fee. The Future Receipts Financing Agreement requires twelve equal payments of $247,000 to be paid monthly for a total repayment of approximate $3.0 million (“Future Receipts”) over the term of the agreement. On February 14, 2024, the Company and Libertas executed an addendum to the Future Receipts Financing Agreement, pursuant to which the monthly payment term was revised to be $185,000 for the first two months and $259,000 for the remaining ten months. The Company has the right to pay to end this financing transaction early by repurchasing the Future Receipts sold to Libertas but not yet delivered. The repurchase price is equal to the discount factor ranging between 1.075-1.165 each month following the Commencement Date up to six months. This shall be multiplied by the purchase price unless amounts collected prior to the date in which the repurchase price is paid.

During the three months ended March 31, 2024, the Company recognized $106,000 interest expense from the amortization of debt discount using the effective interest rate method. As of March 31, 2024, the outstanding balance under the Future Receipts Financing Agreement was $2.4 million, net of debt discount of $396,000.

2023 Secured Mortgage Loan

The Mortgage provided for a loan of $3.3 million (the "Mortgage Loan") with stated maturity date on January 6, 2034, bore a fixed interest rate of 8.25% per annum and required monthly mortgage payments of principal and interest of $25,000. The obligations under the Mortgage Agreement were secured by PREH's certain real property in Pennsylvania. The Company incurred $341,000 issuance cost, which was recognized as a debt discount and will be amortized using the effective interest method over the term of the Mortgage Loan. The Company retains $561,000 and $540,000 cash in an escrow account which was recognized as a restricted cash on the Company's consolidated balance sheet as of March 31, 2024 and December 31, 2023, respectively.

2023 Unsecured Promissory Note Payable

On January 26, 2023, the Company issued an unsecured promissory note (the “JXVII Note”) and guaranty for an aggregate principal amount of $7.6 million to JXVII Trust ("JXVII"). The JXVII Note is due and payable on January 27, 2026, the third anniversary of the date on which the JXVII Note was funded (the “Note Closing Date”), and accrues interest at a rate of 10% per year from the Note Closing Date, payable on a quarterly basis, until the JXVII Note is repaid in full. The Company has the right to prepay the JXVII Note at any time after the Note Closing Date and prior to the maturity date without premium or penalty upon providing seven days’ written notice to the note holder. Repayment of the JXVII Note has been guaranteed by the Company’s wholly-owned subsidiary, PMI. In addition to the JXVII Note, the Company issued warrants to purchase 76,000 shares of the Company's common stock at an exercise price of $9.00 for a term of 5 year, vesting immediately. The warrants were valued at $400,000 fair value, using the Black-Scholes option pricing model to calculate the grant date fair value of the warrants, with the following assumptions: no dividend yield, expected volatility of 81.5%, risk free interest rate of 3.62% and expected warrant life of 5 years. The relative fair value of the warrant was

The 2018 Stock Incentive Plan

On April 12, 2018, the Company's stockholders approved the 2018 Stock Incentive Plan (the “2018 Stock Plan”). The 2018 Stock Plan provides for the grant of incentive stock options to eligible employees of the Company, and for the grant of non-statutory stock options to eligible employees, directors and consultants. The 2018 Stock Plan provides that the total number of shares that may be issued pursuant to the 2018 Stock Plan is 2,300,000 shares. At April 12, 2018, all 2,300,000 shares had been granted in the form of stock options to Ted Karkus (the “CEO Option”), our Chief Executive Officer ("CEO").

The 2018 Stock Plan required certain proportionate adjustments to be made to the stock options granted under the 2018 Stock Plan upon the occurrence of certain events, including a special distribution (whether in the form of cash, shares, other securities, or other property) in order to maintain parity. Accordingly, the Compensation Committee of the board of directors, as required by the terms of the 2018 Stock Plan, adjusted the exercise price of the CEO Option in connection with each special cash dividend paid by the Company proportionately to the amount of the dividend paid. The final exercise price of the CEO Option was $0.60 per share after the latest special cash dividend paid on June 3, 2022.

The COO Award vested 25% on the date of grant and the remaining portion will vest 25% per year for the next three years on each of the first three anniversaries of the commencement date of Mr. Latkin’s employment, subject to his continued service on each vesting date. The COO Award expires on the seventh anniversary of the grant date. The COO Award provides for certain proportionate adjustments to be made in the event of any change in the outstanding shares of common stock of the Company as a result of, among other things, any distribution or special dividend to stockholders of shares, cash or other property (other than regular cash dividends) in order to maintain parity. The grant date fair value of the COO Award was approximately $1.3 million.

The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying options and the closing stock price of $6.47 for the Company’s common stock on March 31, 2024.

During the three months ended March 31, 2024, the Company granted options to purchase 1,790,000 shares of the Company’s common stock to various employees and consultants. The options grant date fair value was valued at $5.3 million during the three months ended March 31, 2024, using the Black-Scholes option pricing model to calculate the grant-date fair value of the options. The fair value of stock options for employees are expensed over the vesting term in accordance with the terms of the related stock option agreements and are expensed over the terms of the consulting agreement for consultants.

The following table summarizes weighted average assumptions used in determining the fair value of the stock options at the date of grant during the three months ended March 31, 2024 and 2023:

Note 7 – Income Taxes

We recognize tax assets and liabilities for future tax consequences related to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and for net operating loss carryforwards. Management evaluated the deferred tax assets for recoverability using a consistent approach that considers the relative impact of negative and positive evidence, including historical profitability and projections of future reversals of temporary differences and future taxable income. We are required to establish a valuation allowance for deferred tax assets if management determines, based on available evidence at the time the determination is made, that it is not more likely than not that some portion or all of the deferred tax assets will be realized. As of March 31, 2024 the Company has net deferred tax liabilities for federal and combined states jurisdictions compared to net deferred tax assets with a full valuation allowance as of December 31, 2023. The decrease in deferred tax assets with a corresponding decrease in valuation allowance against those assets as of March 31, 2024 is primarily due to utilization of net operating losses. The Company has net deferred tax assets in other states jurisdictions where we maintain a full valuation allowance. Judgment is required to estimate forecasted future taxable income, which may be impacted by future business developments, actual results, tax initiatives, legislative, and other economic factors. The Company will continue to monitor income levels and potential changes to its operating and tax model, and other legislative or global developments in its determination.

The Company’s effective tax rate for the three months ended March 31, 2024 is 28.66% and it is primarily driven by federal tax at 21%, state taxes at 0.40%, offset by permanent differences, the research and development credit and state deferred tax benefits.

Note 11 - Earnings Per Share

Basic earnings per share (“EPS”) excludes dilution and is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or otherwise result in the issuance of common stock that shared in the earnings of the entity. Diluted EPS also utilizes the treasury stock method which prescribes a theoretical buy back of shares from the theoretical proceeds of all options outstanding during the period, and the if-converted method for convertible debt.

General

We are a diversified company that offers a range of services including genomics testing, diagnostic testing and contract manufacturing. We are also focused on licensing, developing and commercializing novel drugs, dietary supplements, compounds and diagnostics.

We conduct our operations through two operating segments: diagnostic services and consumer products.

Until late fiscal year 2020, we were engaged primarily in the research, development, manufacture, distribution, marketing and sale of over-the-counter ("OTC") consumer healthcare products and dietary supplements in the United States. This includes the development and marketing of dietary supplements under the TK Supplements® brand. However, commencing in December 2020, we also began offering COVID- 19 and were prepared to validate other RPP Molecular tests through our diagnostic service business. In August 2021 we began offering personal genomics products and services and in July 2022 we began focusing on the licensing, development and commercialization of novel drugs, dietary supplements, compounds and diagnostics.

Our wholly owned subsidiary, ProPhase Diagnostics, Inc. (“ProPhase Diagnostics”), which was formed on October 9, 2020, offers a broad array of clinical diagnostic and testing services at its CLIA certified laboratories including polymerase chain reaction testing for COVID-19. Critical to COVID-19 testing, we provide fast turnaround times for results. We also offer best-in-class rapid antigen testing for COVID-19. On October 23, 2020, we completed the acquisition of all of the issued and outstanding shares of capital stock of Confucius Plaza Medical Laboratory Corp., which owned a 4,000 square foot CLIA accredited laboratory located in Old Bridge, New Jersey for approximately $2.5 million. In December 2020, we expanded our diagnostic service business with the build-out of a second, larger CLIA accredited laboratory in Garden City, New York. Operations at this second facility commenced in January 2021.

On August 10, 2021, we acquired Nebula Genomics, Inc., a privately owned personal genomics company, through our new wholly owned subsidiary, ProPhase Precision Medicine Inc. (“ProPhase Precision”). Subsequently in 2022, ProPhase Precision legal name was changed to Nebula Genomics, Inc. ("Nebula"). Nebula focuses on genomics sequencing technologies, a comprehensive method for analyzing entire genomes, including the genes and chromosomes in DNA. The data obtained from genomic sequencing can be used to help identify inherited disorders and tendencies, help predict disease risk, help identify expected drug response, and characterize genetic mutations, including those that drive cancer progression.

Our wholly owned subsidiary, ProPhase BioPharma, Inc. (“PBIO”) was formed on June 28, 2022, for the licensing, development and commercialization of novel drugs, dietary supplements and compounds, beginning with Equivir and Equivir G. PBIO announced a second licensing agreement for two small molecule proviral integration site for moloney murine leukemia virus kinase inhibitors, Linebacker LB-1 and LB-2, in July 2022, with plans to pursue development and commercialization of LB-1 as a cancer co-therapy.

In January 2023, we acquired exclusive rights to the BE-Smart Esophageal Pre-Cancer Diagnostic Screening Test and related intellectual property assets.

Our wholly owned subsidiary, Pharmaloz Manufacturing, Inc. (“PMI”), is a full-service contract manufacturer and private label developer of a broad range of non-GMO, organic and natural-based cough drops and lozenges and OTC drug and dietary supplement products.

Our diagnostic service business continued to be impacted by the level of demand for COVID-19 and other diagnostic testing and our ability to collect payment or reimbursement for our testing services for the years ended December 31, 2023 and 2022. Due to the significant decrease in demand and reimbursement rate for our diagnostic testing

Table of Contents

service, we have reduced the amount of diagnostic testing services that we provide since the second half of 2023. Nonetheless we are prepared to provide an increased volume of our diagnostic testing service if diagnostic testing is required due to a new COVID-19 outbreak. We have continued to ship COVID-19 antigen kits under an existing contract to our customer. In addition, in order to maintain licenses in certain states in which we operate, we currently perform several diagnostic tests each quarter to maintain our certified lab status, and we currently plan to do so for the foreseeable future.

Our personal genomics business is and will continue to be impacted by demand for our genetic sequencing products and services, our marketing and service capabilities, and our ability to comply with applicable regulatory requirements.

Our consumer sales are and will continue to be impacted by (i) the timing of acceptance of our TK Supplements® consumer products in the marketplace, and (ii) fluctuations in the timing of purchase and the ultimate level of demand for the OTC healthcare and cold remedy products that we manufacture, which is largely a function of the timing, length and severity of each cold season. Generally, a cold season is defined as the period from September to March when the incidence of the common cold rises as a result of the change in weather and other factors. We generally experience in the first, third and fourth quarter higher levels of net revenues from our contract manufacturing business. Revenues are generally at their lowest levels in the second quarter when customer demand generally declines.

In addition, we continue to actively pursue acquisition opportunities for other companies, technologies and products within and outside the consumer products industry.

Results of Operations

Three Months Ended March 31, 2024 as Compared to the Three Months Ended March 31, 2023

For the three months ended March 31, 2024, net revenue was $3.6 million as compared to $19.3 million for the three months ended March 31, 2023. The decrease in net revenue was the result of a $14.5 million decrease in net revenue from diagnostic services, and a $1.1 million decrease in consumer products. The decrease in net revenue for diagnostic services was due to decreased COVID-19 testing volumes compared to the 2023 period as a result of the highly contagious Omicron variant, which emerged in early 2022. Overall diagnostic testing volume decreased from 120,000 tests in the the three months ended March 31, 2023 to zero tests in the three months ended March 31, 2024. None of the tests during the three months ended March 31, 2023 were reimbursed by the HRSA uninsured program.

Cost of revenues for the three months ended March 31, 2024 were $4.1 million, comprised of $0.7 million for diagnostic services and $3.4 million for consumer products. Cost of revenues for the three months ended March 31, 2023 were $8.8 million, comprised of $5.2 million for diagnostic services and $3.6 million for consumer products.

We realized a gross margin loss of $0.4 million for the three months ended March 31, 2024 as compared to a gross margin profit of $10.5 million for the three months ended March 31, 2023. The decrease of $10.9 million was comprised of a decrease of $10.0 million in diagnostic services, and a decrease of $0.9 million in consumer products. For the three months ended March 31, 2024 and 2023 we realized an overall gross margin of (11.9)% and 54.5%, respectively. Gross margin for diagnostic services was zero or not applicable due to no revenue and 64.0% in the 2024 and 2023 comparable periods, respectively. Gross margin for consumer products was 7.8% and 25.5% in the 2024 and 2023 comparable periods, respectively. Gross margin for consumer products have historically been influenced by fluctuations in quarter-to-quarter production volume, fixed production costs and related overhead absorption, raw ingredient costs, inventory mark to market write-downs and timing of shipments to customers.

Diagnostic services costs for the three months ended March 31, 2024 were zero compared to $1.2 million for the three months ended March 31, 2023. The decrease in diagnostic service costs of $1.2 million for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023 was due to decreased COVID-19 testing volumes in 2024 compared to the 2023 period.

General and administration expenses for the three months ended March 31, 2024 were $7.6 million as compared to $8.3 million for the three months ended March 31, 2023. The decrease in general and administration expenses of $0.7 million for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023 was principally related to a decrease in personnel expenses and professional fees associated with our diagnostic services business.

Table of Contents

Research and development costs for the three months ended March 31, 2024 were $272,000 as compared to $144,000 for the three months ended March 31, 2023. The increase in research and development costs of $128,000 for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023 was principally due to increased activities at PBIO. These activities include product research and field testing.

Interest and other income for the three months ended March 31, 2024 was zero as compared to $11,000 for the three months ended March 31, 2023. The decrease in interest income of $11,000 for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023 was principally due to the lower account balance of our investment account that bears interest.

Interest expense for the three months ended March 31, 2024 was $515,000 as compared to $215,000 for the three months ended March 31, 2023. The increase in interest expense of $300,000 for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023 was principally due to the higher balance of our outstanding debt that bears interest and leased manufacturing equipment.

As a result of the effects described above, net loss for the three months ended March 31, 2024 was $6.3 million, or $(0.35) per share, as compared to net income of $0.6 million, or $0.03 per share, for the three months ended March 31, 2023. Diluted loss and earnings per share for the three months ended March 31, 2024 and 2023 were $(0.35) and $0.03, respectively.

Non-GAAP Financial Measures and Reconciliation

In an effort to provide investors with additional information regarding our results of operations as determined by accounting principles generally accepted in the United States of America (“GAAP”), we disclose certain non-GAAP financial measures. The primary non-GAAP financial measures we disclose are EBITDA and Adjusted EBITDA.

We define "EBITDA" as net income (loss) before net interest expense, income taxes, depreciation and amortization. Adjusted EBITDA further adjusts EBITDA by excluding acquisition costs, other non-cash items, and other unusual or non-recurring charges (as described in the table below).

Non-GAAP financial measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. These non-GAAP financial measures do not reflect a comprehensive system of accounting, differ from GAAP measures with the same names and may differ from non-GAAP financial measures with the same or similar names that are used by other companies. We compute non-GAAP financial measures using the same consistent method from quarter to quarter and year to year. We may consider whether other significant items that arise in the future should be excluded from the non-GAAP financial measures.

We use EBITDA and Adjusted EBITDA internally to evaluate and manage the Company’s operations because we believe they provide useful supplemental information regarding the Company’s ongoing economic performance. We believe that these non-GAAP financial measures provide meaningful supplemental information regarding our operating results primarily because they exclude amounts that are not considered part of ongoing operating results when planning and forecasting and when assessing the performance of the organization. In addition, we believe that non-GAAP financial information is used by analysts and others in the investment community to analyze our historical results and in providing estimates of future performance and that failure to report these non-GAAP measures could result in confusion among analysts and others and create a misplaced perception that our results have underperformed or exceeded expectations.

Table of Contents

The following table sets forth the reconciliations of EBITDA and Adjusted EBITDA excluding other costs to the most comparable GAAP financial measures (in thousands):


	For the three months ended
	March 31, 2024		March 31, 2023
GAAP net income (1)	$	(6,265)	$	550
Interest, net	515		204
Income tax (benefit) expense	(2,566)		14
Depreciation and amortization	1,686		1,292
EBITDA	(6,630)		2,060
Share-based compensation expense	1,589		947

Non-cash rent expense (2)	169		6
Credit loss expense	—		74
Adjusted EBITDA	$	(4,872)	$	3,087

(1)We believe that net income (loss) is the financial measure calculated and presented in accordance with GAAP that is most directly comparable to EBITDA and Adjusted EBITDA. EBITDA and Adjusted EBITDA measure the Company’s operating performance without regard to certain expenses. EBITDA and Adjusted EBITDA are not presentations made in accordance with GAAP and the Company’s computation of EBITDA and Adjusted EBITDA may vary from others in the industry. EBITDA and Adjusted EBITDA have important limitations as analytical tools and should not be considered in isolation or as substitutes for analysis of the Company’s results as reported under GAAP.

(2)The non-cash portion of rent, which reflects the extent to which our GAAP rent expense recognized exceeds (or is less than) our cash rent payments. For newer leases, our rent expense recognized typically exceeds our cash rent payments, while for more mature leases, rent expense recognized is typically less than our cash rent payments.

Liquidity and Capital Resources

Our aggregate cash and cash equivalents as of March 31, 2024 were $1.7 million as compared to $2.1 million at December 31, 2023. Our working capital was $21.1 million and $26.7 million as of March 31, 2024 and December 31, 2023, respectively. The decrease of $0.4 million in our cash and cash equivalents for the three months ended March 31, 2024 was principally due to the proceeds from the sale of marketable debt securities of $3.4 million, and proceeds from issuance of notes payable and mortgage loan of $2.5 million, offset by (i) $5.1 million cash used in operating activities, (ii) capital expenditures of $0.9 million, and (iii) repayment of notes payable for $189,000.

To date the principal sources of capital to fund our operations have been from diagnostic services, genomics sequencing, product sales, net proceeds from the offering of equity securities, and issuances of promissory notes. Based on management’s current business plans, the Company estimates it will have enough cash and liquidity to finance its operating requirements for at least 12 months from the date of filing these unaudited condensed consolidated financial statements. However, due to the nature of early-stage ventures and accounts receivables collections, there are inherent uncertainties associated with managements’ business plan and cash flow projections, particularly if the Company is unable to grow its business lines, including replacing the revenues from our lab diagnostic services or tests with new business lines, or collect on its accounts receivables in a timely manner or at all. If we were to experience a cash shortfall, we believe our access to existing and other financing sources, including our at-the-market facility, and the established relationships with our investment banks will enable us to continue to meet our obligations and fund ongoing operations.

We may also use our cash to explore and/or acquire new product technologies, applications, product line extensions, new contract manufacturing applications and other new product opportunities. In the event that our available cash is insufficient to support such initiatives, we may need to incur indebtedness or issue common stock or other securities to finance our plans for growth. Volatility in the credit markets and the liquidity of major financial institutions, including as a result of inflation and/or the wars in Ukraine and the Gaza Strip and measures taken in response thereto, may have an adverse impact on our ability to fund our business strategy through future borrowings, under either existing or newly created instruments in the public or private markets on terms that we believe to be reasonable, if at all.

Table of Contents

We anticipate that we will continue to incur losses for foreseeable future. We expect to continue to incur research and development costs and general and administrative expenses, as well as expenses related to potential commercialization of our product candidates, consistent with costs associated with research and development at companies of our size and stage of development, and, as a result, we will need additional capital to fund our operations, which we may raise through public or private equity or debt financings, strategic collaborations, or other sources.

COVID-19

Previously, we experienced higher than normal net revenue for the years ended December 31, 2021 and 2022, primarily as a result of increased revenue from our diagnostic services business. The increase in net revenue from diagnostic services was due to increased COVID-19 testing volumes performed as a result of the spread of the Omicron variant, which emerged in early 2022. The demand for our COVID-19 testing services significantly decreased starting in the second half of 2022, partly due to the widespread and effective vaccination of a majority of Americans against COVID-19 and successful containment efforts. As a result, we have reduced the amount of diagnostic testing services that we provide since the second half of 2023, and for the three months ended March 31, 2024, we formed zero diagnostic test. Nonetheless we are prepared to provide an increased volume of our diagnostic testing service if diagnostic testing is required due to a new COVID-19 outbreak. We have continued to ship COVID-19 antigen kits under an existing contract to our customer. In addition, in order to maintain licenses in certain states in which we operate, we currently perform several diagnostic tests each quarter to maintain our certified lab status, and we currently plan to do so for the foreseeable future.

Contractual Obligation and Commitments

Manufacturing Agreement

The Company and its wholly owned subsidiary, PMI, entered into a manufacturing agreement (the “Manufacturing Agreement”) with Mylan Consumer Healthcare Inc. (“MCH”) and Mylan Inc. (together with MCH, “Mylan”) in connection with the asset purchase agreement we entered into with Mylan in 2017. Pursuant to the terms of the Manufacturing Agreement, Mylan (or an affiliate or designee) purchased the inventory of the Company’s Cold-EEZE® brand and product line, and PMI agreed to manufacture certain products for Mylan, as described in the Manufacturing Agreement, at prices that reflect current market conditions for such products and include an agreed upon mark-up on our costs. On May 1, 2021, the Manufacturing Agreement was assigned by Mylan to Nurya Brands, Inc. (“Nurya”) in connection with Nurya’s acquisitions of certain assets from Mylan, including the Cold-EEZE® brand and product line. Unless terminated sooner by the parties, the Manufacturing Agreement was to remain in effect until March 29, 2023. Thereafter, the Manufacturing Agreement could be renewed by Nurya for up to four successive one-year periods by providing notice of its intent to renew not less than 90 days prior to the expiration of the then-current term.

Equivir License Agreement

Under the terms of our Equivir License Agreement with Global BioLife for the worldwide exclusive right and license to Equivir and Equivir G, we are required to pay to Global BioLife a royalty of 5.5% after the date of first commercial sale and during the royalty term. In the event that no valid claim of Equivir Licensed Patents cover a Equivir Licensed Product in a particular jurisdiction, the royalty rate for such Equivir Licensed Product will be reduced by 50%.

Product, but no less than the minimum royalty of $250,000 of Net Revenue per year minus any royalty payments for any required third party licenses.

Stella Asset Purchase Agreement

On December 15, 2022, we entered into an Asset Purchase Agreement (the “Stella Purchase Agreement”) with Stella Diagnostics Inc. (“Stella”) and Stella DX, LLC (“Stella DX” and, together with Stella, the “Stella Sellers”), pursuant to which, on January 3, 2023, we purchased all of the assets, rights and interests of the Stella Sellers and their affiliates pertaining to the Stella Sellers’ BE-Smart Esophageal Pre-Cancer diagnostic screening test and certain clinical assets, including all intellectual property rights (the “Stella Purchased Assets”). As consideration for the Stella Purchased Assets, we (i) paid to the Stella Sellers $3.5 million in cash, minus (a) the Secured Note Amount of $0.5 million, (b) the Liability Payoff Amount of $0.4 million and (c) the Promissory Note Payoff Amounts of $0.4 million (each as defined in the Stella Purchase Agreement) in 2022, and (ii) issued to Stella DX 100,000 shares of our common stock.

We are required to pay to the Stella Sellers for each of the seven calendar years (each, an “Annual Period”) during the seven year period commencing on the first day of the calendar year following the date of the Commercialization Event (as defined in the Stella Purchase Agreement), a non-refundable, non-creditable royalty of 5% of the Adjusted Gross Margin (as defined in the Stella Purchase Agreement) for such Annual Period.

JXVII Trust Promissory Note

On January 26, 2023, we issued an unsecured promissory note and guaranty for an aggregate principal amount of $7.6 million (the "JXVII Note") to JXVII Trust (“JXVII”). The JXVII Note is due and payable on January 27, 2026, the third anniversary of the date on which the JXVII Note was funded (the “Note Closing Date”), and accrues interest at a rate of 10% per year from the Note Closing Date, payable on a quarterly basis, until the JXVII Note is repaid in full. We have the right to prepay the JXVII Note at any time after the Note Closing Date and prior to the maturity date without premium or penalty upon providing seven days’ written notice to JXVII. Repayment of the JXVII Note has been guaranteed by the Company’s wholly-owned subsidiary, PMI.

The JXVII Note contains customary events of default. If a default occurs and is not cured within the applicable cure period or is not waived, any outstanding obligations under the JXVII Note may be accelerated. The JXVII Note also contains certain restrictive covenants which, among other things, restrict our ability to create, incur, assume or permit to exist, directly or indirectly, any lien (other than certain permitted liens described in the JXVII Note) securing any indebtedness of the Company, and prohibits us from distributing or reinvesting the proceeds from any divestment of assets (other than in the ordinary course) without the prior approval of JXVII.

HRSA Funding

In March 2020, the Coronavirus Aid, Relief, and Economic Security Act was enacted, providing for reimbursement to healthcare providers for COVID-19 tests provided to uninsured individuals, subject to continued available funding. There were no diagnostic services revenue for the three months ended March 31, 2024 and 2023, respectively, that was generated from this program for the uninsured. On March 22, 2022, the Health Resources & Services Administration's uninsured program stopped accepting claims for COVID-19 testing and treatment due to lack of sufficient funds. Despite requests from the Acting Director of the Office of Management and Budget and the White House Coordinator for COVID-19 Response for additional emergency funding for the uninsured program, additional emergency funding were not allocated to the Health Resources & Services Administration's uninsured program.

On January 30, 2023, the Administration announced that effective May 11, 2023, the federal Public Health Emergency would expire related to the COVID-19 pandemic. This expiration changes regulatory guidelines around COVID-19 testing including billing codes and reimbursement rates of in and out of network laboratories. As a result of the Public Health Emergency ending and the significant decrease in demand of COVID-19 testing, we have reduced the amount of diagnostic testing services that we provide since the second half of 2023.

At-the-Market Facility

On December 28, 2021, we entered into a Sales Agreement (the “Sales Agreement”) with ThinkEquity LLC (the “Sales Agent”), pursuant to which we may offer and sell, from time to time through the Sales Agent, shares of our common

Table of Contents

stock having an aggregate offering price of up to $100,000,000, subject to the terms and conditions of the Sales Agreement. We are not obligated to make any sales of shares under the Sales Agreement.

We will pay the Sales Agent a fixed commission rate of 2.0% of the aggregate gross proceeds from the sale of any shares pursuant to the Sales Agreement and have agreed to provide the Sales Agent with customary indemnification and contribution rights. We also agreed to reimburse the actual out-of-pocket accountable expenses of the Sales Agent up to $60,000 (of which a $25,000 advance was paid on December 7, 2021), which amount includes the fees and expenses of legal counsel to the Sales Agent up to $50,000, and to pay the costs associated with bound volumes of the public offering materials as well as commemorative mementos and lucite tombstones, in an amount not to exceed $3,000.

Additionally, we will pay to H.C. Wainwright & Co. (“Wainwright”), a fee equal to 1.0% of the gross proceeds of the sales price of all the shares sold under the Sales Agreement, pursuant to a separate financial services agreement with Wainwright. Wainwright is not a sales agent under the Sales Agreement.

For the three months ended, and as of, March 31, 2024, we did not sell, and have not sold, any shares under the Sales Agreement.

See Note 12 of the Notes to the Condensed Consolidated Financial Statements, Subsequent Events for more information relating to a certain standstill agreement that we entered into with the Sales Agent on April 18, 2024.

Impact of Inflation

We are subject to normal inflationary trends and anticipate that any increased costs for our contract manufacturing and retail operations would be passed on to our customers; however, any increased costs related to diagnostic services would be absorbed by the Company. Inflation could have a material effect on our business in the future.

Critical Accounting Policies and Estimates

Our significant accounting policies are described in Note 2 of the Notes to Condensed Consolidated Financial Statements included under Item 8 of this Part II. However, certain accounting policies are deemed “critical”, as they require management’s highest degree of judgment, estimates and assumptions. These accounting policies, estimates and disclosures have been discussed with the Audit Committee of our Board of Directors. A discussion of our critical accounting policies and estimates, the judgments and uncertainties affecting their application and the likelihood that materially different amounts would be reported under different conditions or using different assumptions are as follows:

Use of Estimates

The preparation of condensed consolidated financial statements and the accompanying notes thereto, in conformity with GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and reported amounts of revenues and expenses during the respective reporting periods. Examples include revenue recognition and the estimation of the variable consideration associated with the diagnostic reimbursement rates, the allowance for credit losses and billing discrepancies, sales returns and allowances, inventory obsolescence, useful lives of property and equipment, impairment of goodwill, intangibles and property and equipment, income tax valuations and assumptions related to accrued advertising. The estimates and assumptions are based on historical experience, current trends and other factors that management believes to be relevant at the time the condensed consolidated financial statements are prepared. Management reviews the accounting policies, assumptions, estimates and judgments on a quarterly basis. Actual results could differ from those estimates.

Revenue Recognition and Accounts Receivables

We generate revenue principally through four types of revenue streams: diagnostic services, contract manufacturing, genomic products and services, and retail and other. The process for estimating revenues and the ultimate collection of receivables involves assumptions and judgments.

Revenue from our diagnostic services is recognized when the lab test is complete, and the diagnostic test result is provided to the customer. Revenue from our genomics services is recognized when the sequencing report is provided to the customer. Revenue from our consumer products is recognized when the shipments to contract manufacturing and retailer

Table of Contents

customers are recognized at the time ownership is transferred to the customer. We bill the providers at standard price and take into consideration for negotiated discounts and an anticipated reimbursement remittance adjustments based on the payer portfolio, when revenue is recorded. We use the most expected value method to estimate the transaction price for reimbursements that may vary from the standard price.

We carry our accounts receivable at cost less an allowance for credit losses. Allowances for credit losses are based upon our judgment regarding collectability. On a periodic basis, we evaluate our receivables and establish an allowance for credit losses, based on a history of past write-offs, collections, current credit conditions or generally accepted future trends in the industry and/or local economy. Accounts are written off as uncollectible at the time we determine that collections are unlikely. The reserve is not intended to address return activity or disputed balances with ongoing customers, as this should be addressed in a reserve for credit memos with a corresponding charge to revenue.

Goodwill and Long-lived Assets

We review our goodwill at least annually for impairment as well as the carrying value of goodwill and our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of these assets may not be fully recoverable. When it is determined that the carrying amount of long-lived assets or goodwill is impaired, impairment is measured by comparing an asset’s estimated fair value to its carrying value. The determination of fair value is based on quoted market prices in active markets, if available, or independent appraisals; sales price negotiations; or projected future cash flows discounted at a rate determined by management to be commensurate with our business risk. The estimation of fair value utilizing discounted forecasted cash flows includes significant judgments regarding assumptions of revenue, operating and marketing costs; selling and administrative expenses; interest rates; property and equipment additions and retirements; and industry competition, general economic and business conditions, among other factors.

Income Taxes

Accounting for income taxes requires recognition of deferred tax liabilities and assets for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities. These deferred taxes are measured by applying the provisions of tax laws in effect at the balance sheet date, including the impact of the Tax Cuts and Jobs Act (“TCJA”) enacted on December 22, 2017. The TCJA made broad and significant changes to the U.S. tax code that affects the year ended December 31, 2017, including, but not limited to, a change in the federal rate from 35% to 21% effective January 1, 2018.

We recognize in income the effect of a change in tax rates on deferred tax assets and liabilities in the period that includes the TCJA enactment date. We utilize the asset and liability approach which requires the recognition of deferred tax assets and liabilities for the future tax consequences of events that have been recognized in our financial statements or tax returns. In estimating future tax consequences, we generally consider all expected future events other than enactments of changes in the tax law or rates. Until sufficient taxable income to offset the temporary timing differences attributable to operations and the tax deductions attributable to option, warrant and stock activities are assured, a valuation allowance equaling the total net current and non-current deferred tax asset is being provided.

Inventories

Inventory is valued at the lower of cost, determined on a first-in, first-out basis (“FIFO”), or net realizable value. We regularly review inventory quantities on hand and record a provision for excess and obsolete inventory based primarily on current and anticipated customer demand, production and laboratory requirements.

Recently Issued Accounting Standards, Adopted

In March 2024, the FASB issued ASU No. 2024-01, “Compensation-Stock Compensation (Topic 718): Scope Applications of Profits Interests and Similar Awards” ("ASU 2024-01"). ASU 2024-01 adds an example to Topic 718 which illustrates how to apply the scope guidance to determine whether profits interests and similar awards should be accounted for as share-based payment arrangements under Topic 718 or under other U.S. GAAP. ASU 2024-01 is effective for annual periods beginning after December 15, 2024, although early adoption is permitted. Upon adoption, ASU 2024-01 is not expected to have an impact on the Company’s condensed consolidated financial statements.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

Like virtually all commercial enterprises, we can be exposed to the risk (“market risk”) that the cash flows to be received or paid relating to certain financial instruments could change as a result of changes in interest rate, exchange rates, commodity prices, equity prices and other market changes.

Our operations are not subject to risks of material foreign currency fluctuations, nor do we use derivative financial instruments in our investment practices. We place our marketable investments in instruments that meet high credit quality standards. We do not expect material losses with respect to our investment portfolio or excessive exposure to market risks associated with interest rates. The impact on our results of one percentage point change in short-term interest rates would not have a material impact on our future earnings, fair value, or cash flows related to investments in cash equivalents or interest-earning marketable securities.

Current economic conditions may cause a decline in business and consumer spending which could adversely affect our business and financial performance including the collection of accounts receivables, notes receivable, realization of inventory and recoverability of assets. In addition, our business and financial performance may be adversely affected by current and future economic conditions, including a reduction in the availability of credit, financial market volatility and recession.

Except for the broad effects of COVID-19 including its negative impact on the global economy and major financial markets, there have been no material changes to our market risk exposures since December 31, 2023.

Item 4. Controls and Procedures.

Disclosure Controls and Procedures

Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in our reports filed with or submitted to the SEC under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our reports filed under the Exchange Act is accumulated and communicated to management, including our principal executive officer and principal financial and accounting officer, to allow timely decisions regarding required disclosure.

We carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of March 31, 2024. This evaluation was carried out under the supervision and with the participation of our principal executive officer and principal financial and accounting officer. Based on that review, our management, including our principal executive officer and principal financial and accounting officer, concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of March 31, 2024.

Material Weakness

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our financial statements could occur but will not be prevented or detected on a timely basis. In connection with our 2023 Annual Report, our management conducted an evaluation of the effectiveness of our system of internal control over financial reporting based on the framework in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework). Based upon that review, our management, including our principal executive officer and principal financial and accounting officer, concluded that the Company’s internal controls over financial reporting were not effective as of December 31, 2023 due to the material weaknesses described below.

•We did not adequately review certain account reconciliations or controls over the financial statement closing process, which resulted in misstatements in account reconciliations and resulted in several proposed unadjusted journal entries.

•Several errors were made related to recording revenue in the proper period, calculating current period revenue, and following Company policy regarding principal versus agent considerations, resulting in misstatements in accounts receivable, deferred revenue, and revenue for multiple subsidiaries. We relied heavily on the manual

Table of Contents

input process for these areas and it did not properly design and maintain controls to identify exceptions. In certain instances where revenue is recorded based on an estimation of rates, process were not in place to properly update the rates accordingly throughout the year.

•We did not design and maintain adequate controls over the identification of discrepancies relating to the calculated and recorded deferred costs and cost of sales, which such calculation and recording relied heavily on the manual input process and resulted in misstatements in deferred costs and cost of sales.

Remediation Plan

We are in the process of continuing to evaluate the material weaknesses and developing a detailed plan for remediation of the material weakness. The Company has hired a third-party accounting consultant and has recently added personnel to aid in implementing additional levels of review and approval. We will not consider the material weakness remediated until the remedial controls operate for a sufficient period of time and we have concluded, through testing, that these controls are effectively designed and operating effectively. We will continue to assess the effectiveness of our remediation efforts in connection with our future assessments of the effectiveness of internal control over financial reporting and disclosure controls and procedures throughout 2024. As we continue to evaluate and work to improve our internal control over financial reporting, we may execute additional measures to address potential control deficiencies or modify the remediation plan described above. We will continue to review and make necessary changes to the overall design of our internal control.

Changes in Internal Control Over Financial Reporting

Except as described above, no change in internal control over financial reporting occurred during the most recent quarter with respect to our operations, which materially affected, or is reasonable likely to materially affect, our internal controls over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings.

From time to time, we have been and may again become involved in legal proceedings arising in the ordinary course of business. We are not presently a party to any material litigation.

TK Supplements, Inc., was the defendant in Aviles v. TK Supplements, Inc., a purported class action pending in the Superior Court for the State of California, County of Los Angeles. In the complaint that was filed on April 27, 2023, the plaintiff alleged that TK Supplements falsely advertised its Legendz XL male enhancement supplement in violation of California’s Consumer Legal Remedies Act. We believed the lawsuit and the allegations contained therein were without merit, and on February 6, 2024, the matter was voluntarily dismissed as a result of a negotiated resolution.

Item 1A. Risk Factors.

Factors that could cause our actual results to differ materially from those in this Quarterly Report are any of the risks described in our Annual Report on Form 10-K filed with the SEC on March 29, 2024. Any of these factors could result in a significant or material adverse effect on our results of operations or financial condition. Additional risk factors not presently known to us or that we currently deem immaterial may also impair our business or results of operations. 

As of the date of this Quarterly Report on Form 10-Q, there have been no material changes to the risk factors disclosed in our Annual Report on Form 10-K filed with the SEC on March 29, 2024. However, we may disclose changes to such factors or disclose additional factors from time to time in our future filings with the SEC. 

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Business	Organization and Business ProPhase Labs, Inc. (“ProPhase”, “we”, “us”, “our” or the “Company”) is a diversified company that offers a range of services including genomics testing, diagnostic testing and contract manufacturing. We are also focused on licensing, developing and commercializing novel drugs, dietary supplements, compounds and diagnostics. Until late fiscal year 2020, the Company was engaged primarily in the research, development, manufacture, distribution, marketing and sale of over-the-counter ("OTC") consumer healthcare products and dietary supplements in the United States. In October 2020, the Company completed the acquisition of all of the issued and outstanding shares of capital stock of Confucius Plaza Medical Laboratory Corp. (“CPM”), which owned a 4,000 square foot Clinical Laboratory Improvement Amendments (“CLIA”) accredited laboratory located in Old Bridge, New Jersey for approximately $2.5 million, and began offering COVID-19 diagnostic tests through our wholly-owned subsidiary, ProPhase Diagnostics, Inc. ("ProPhase Diagnostics") in December 2020. Also in December 2020, we expanded our diagnostic service business with the build-out of a second, larger CLIA accredited laboratory in Garden City, New York. Operations at this second facility commenced in January 2021. We offered a broad array of COVID-19 related clinical diagnostic and testing services including polymerase chain reaction testing for COVID-19 and Influenza A and B through ProPhase Diagnostics, as well as rapid antigen and antibody/immunity testing for COVID-19. Due to the significant decrease in demand and reimbursement rate for our diagnostic testing service, we have reduced the amount of diagnostic testing services that we provide since the second half of 2023. Nonetheless we are prepared to provide an increased volume of our diagnostic testing service if diagnostic testing is required due to a new COVID-19 outbreak. We have continued to ship COVID-19 antigen kits under an existing contract to our customer. In addition, in order to maintain licenses in certain states in which we operate, we currently perform several diagnostic tests each quarter to maintain our certified lab status, and we currently plan to do so for the foreseeable future. In August 2021, the Company acquired Nebula Genomics, Inc. (“Nebula”), a privately owned personal genomics company, through our wholly-owned subsidiary, ProPhase Precision Medicine Inc. Nebula focuses on genomics sequencing technologies, a comprehensive method for analyzing entire genomes, including the genes and chromosomes in deoxyribonucleic acidDNA. The data obtained from genomic sequencing can be used to help identify inherited disorders and tendencies, help predict disease risk, help identify expected drug response, and characterize genetic mutations, including those that drive cancer progression. The Company's wholly owned subsidiary, ProPhase BioPharma, Inc. (“PBIO”), was formed in June 2022, for the licensing, development and commercialization of novel drugs, dietary supplements and compounds. Licensed compounds currently include Equivir (a OTC, dietary supplement candidate) and Equivir G (prescription drug candidate), two broad-based anti-virals, and Linebacker LB-1 and LB-2, two small molecule proviral integration site for moloney murine leukemia virus kinase inhibitors. The Company also own the exclusive rights to the BE-Smart Esophageal Pre-Cancer Diagnostic Screening test and related intellectual property assets. In connection with the activities of PBIO, in January 2023, the Company acquired exclusive rights to BE-Smart Esophageal Pre-Cancer Diagnostic Screening test and related intellectual property assets. The BE-Smart test is focused on the early detection of esophageal cancer, and is intended to provide health care providers and patients with data to help determine treatment options. The development of these novel drugs and compounds is highly dependent on how each performs during the testing and development stage, the demand for these product and services once entered into the marketplace, our marketing and service capabilities and our ability to comply with applicable regulatory requirements. The Company's wholly-owned subsidiary, Pharmaloz Manufacturing, Inc. (“PMI”), is a full-service contract manufacturer and private label developer of a broad range of non-GMO, organic and natural-based cough drops and lozenges and OTC drug and dietary supplement products. The Company also develops and markets dietary supplements under the TK Supplements® brand. The TK Supplements® product line includes Legendz XL®, a male sexual enhancement and Triple Edge XL®, an energy and stamina booster. The Company's wholly owned subsidiary, Pharmaloz Real Estate Holdings, Inc. (“PREH”), was formed in November 2023, for the purpose to receive additional investment to expand its current facility. There were no operations for PREH as of March 31, 2024. The Company continues to actively pursue acquisition opportunities for other companies, technologies and products within and outside the consumer products industry.

Asset Acquisition	Mar. 31, 2024
Business Combination and Asset Acquisition [Abstract]
Asset Acquisition	Asset Acquisition Stella Diagnostics - Asset Purchase Agreement On December 15, 2022, the Company entered into an Asset Purchase Agreement (the “Stella Purchase Agreement”), with Stella Diagnostics Inc. (“Stella”) and Stella DX, LLC (“Stella DX” and, together with Stella, the “Stella Sellers”), pursuant to which, on January 3, 2023, the Company purchased all of the assets, rights and interests of the Stella Sellers and their affiliates pertaining to the Stella Sellers’ BE-Smart Esophageal Pre-Cancer Diagnostic Screening Test and certain clinical assets, including all intellectual property rights (the “Stella Purchased Assets”). As consideration for the Stella Purchased Assets, at closing, the Company (i) paid to the Stella Sellers $3.5 million in cash, minus (a) the Secured Note Amount of $0.5 million, (b) the Liability Payoff Amount of $1.6 million and (c) the Promissory Note Payoff Amount of $0.4 million, and (ii) issued to Stella DX 100,000 shares of common stock, par value $0.0005 per share, of the Company at a value of $10.00 per share. Total consideration paid was $4.6 million. The Secured Note Amount of $0.5 million and the Promissory Note Payoff of $0.4 million were paid in 2022. The balance of the consideration was paid at closing on January 3, 2023. In addition to the consideration paid at closing, the Company will issue shares of common stock valued at $2.0 million to the Stella Sellers upon a Commercialization Event (as defined in the Stella Purchase Agreement). Such stock was recorded at closing as a non-current liability at its fair value of $2.0 million. Also, the Company is required to pay to the Stella Sellers for each of the seven calendar years during the seven year period commencing on the first day of the calendar year following the date of the Commercialization Event, a non-refundable, non-creditable royalty of 5% of the Adjusted Gross Margin (as defined in the Stella Purchase Agreement) for such annual period. The asset purchase does not qualify as a business combination under ASC 805, Business Combinations, and has therefore been accounted for as an asset acquisition. In connection with the Stella Purchased Assets, the Company incurred $0.2 million in transaction costs, which were capitalized into the purchase price of the Stella Purchased Assets. The total purchase price for the Stella Purchased Assets was $6.8 million, which was allocated to the proprietary technology intangible asset acquired. The Company is amortizing the acquired intangible asset on a straight-line basis over its estimated useful life of five years.

Outstanding Debt	Outstanding Debt 2024 Future Receipts Financing On February 14, 2024 (the “Commencement Date”), the Company entered into an agreement of sale of future receipts (“Future Receipts Financing Agreement”) with Libertas Funding, LLC (“Libertas”) by which Libertas purchases from the Company, its future accounts and contract rights arising from the sale of goods or rendition of services to the Company’s customers. The purchase price was approximate $2.5 million, which was paid to the Company on February 16, 2024, net of $50,000 origination fee. The Future Receipts Financing Agreement requires twelve equal payments of $247,000 to be paid monthly for a total repayment of approximate $3.0 million (“Future Receipts”) over the term of the agreement. On February 14, 2024, the Company and Libertas executed an addendum to the Future Receipts Financing Agreement, pursuant to which the monthly payment term was revised to be $185,000 for the first two months and $259,000 for the remaining ten months. The Company has the right to pay to end this financing transaction early by repurchasing the Future Receipts sold to Libertas but not yet delivered. The repurchase price is equal to the discount factor ranging between 1.075-1.165 each month following the Commencement Date up to six months. This shall be multiplied by the purchase price unless amounts collected prior to the date in which the repurchase price is paid. During the three months ended March 31, 2024, the Company recognized $106,000 interest expense from the amortization of debt discount using the effective interest rate method. As of March 31, 2024, the outstanding balance under the Future Receipts Financing Agreement was $2.4 million, net of debt discount of $396,000. 2023 Secured Mortgage Loan On December 20, 2023, the Company's wholly-owned subsidiary PREH entered into an Open-End Mortgage Agreement (the "Mortgage Agreement"). The Mortgage provided for a loan of $3.3 million (the "Mortgage Loan") with stated maturity date on January 6, 2034, bore a fixed interest rate of 8.25% per annum and required monthly mortgage payments of principal and interest of $25,000. The obligations under the Mortgage Agreement were secured by PREH's certain real property in Pennsylvania. The Company incurred $341,000 issuance cost, which was recognized as a debt discount and will be amortized using the effective interest method over the term of the Mortgage Loan. The Company retains $561,000 and $540,000 cash in an escrow account which was recognized as a restricted cash on the Company's consolidated balance sheet as of March 31, 2024 and December 31, 2023, respectively. 2023 Unsecured Promissory Note Payable On January 26, 2023, the Company issued an unsecured promissory note (the “JXVII Note”) and guaranty for an aggregate principal amount of $7.6 million to JXVII Trust ("JXVII"). The JXVII Note is due and payable on January 27, 2026, the third anniversary of the date on which the JXVII Note was funded (the “Note Closing Date”), and accrues interest at a rate of 10% per year from the Note Closing Date, payable on a quarterly basis, until the JXVII Note is repaid in full. The Company has the right to prepay the JXVII Note at any time after the Note Closing Date and prior to the maturity date without premium or penalty upon providing seven days’ written notice to the note holder. Repayment of the JXVII Note has been guaranteed by the Company’s wholly-owned subsidiary, PMI. In addition to the JXVII Note, the Company issued warrants to purchase 76,000 shares of the Company's common stock at an exercise price of $9.00 for a term of 5 year, vesting immediately. The warrants were valued at $400,000 fair value, using the Black-Scholes option pricing model to calculate the grant date fair value of the warrants, with the following assumptions: no dividend yield, expected volatility of 81.5%, risk free interest rate of 3.62% and expected warrant life of 5 years. The relative fair value of the warrant was $380,000 and was recorded as a discount to the note payable in accordance with ASC 835-30-25, Recognition, and is being accreted over the term of the note payable for financial statement purposes. As of March 31, 2024, the unpaid principal balance of the JXVII Note was $7.4 million, net of debt discount of $232,000.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We recognize tax assets and liabilities for future tax consequences related to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and for net operating loss carryforwards. Management evaluated the deferred tax assets for recoverability using a consistent approach that considers the relative impact of negative and positive evidence, including historical profitability and projections of future reversals of temporary differences and future taxable income. We are required to establish a valuation allowance for deferred tax assets if management determines, based on available evidence at the time the determination is made, that it is not more likely than not that some portion or all of the deferred tax assets will be realized. As of March 31, 2024 the Company has net deferred tax liabilities for federal and combined states jurisdictions compared to net deferred tax assets with a full valuation allowance as of December 31, 2023. The decrease in deferred tax assets with a corresponding decrease in valuation allowance against those assets as of March 31, 2024 is primarily due to utilization of net operating losses. The Company has net deferred tax assets in other states jurisdictions where we maintain a full valuation allowance. Judgment is required to estimate forecasted future taxable income, which may be impacted by future business developments, actual results, tax initiatives, legislative, and other economic factors. The Company will continue to monitor income levels and potential changes to its operating and tax model, and other legislative or global developments in its determination. The Company’s effective tax rate for the three months ended March 31, 2024 is 28.66% and it is primarily driven by federal tax at 21%, state taxes at 0.40%, offset by permanent differences, the research and development credit and state deferred tax benefits.

Commitments and Contingencies	Commitments and Contingencies Manufacturing Agreement The Company and its wholly owned subsidiary, PMI, entered into a manufacturing agreement (the “Manufacturing Agreement”) with Mylan Consumer Healthcare Inc. (formerly known as Meda Consumer Healthcare Inc.) (“MCH”) and Mylan Inc. (together with MCH, “Mylan” in connection with the asset purchase agreement we entered into with Mylan in 2017. Pursuant to the terms of the Manufacturing Agreement, Mylan (or an affiliate or designee) purchased the inventory of the Company’s Cold-EEZE® brand and product line, and PMI agreed to manufacture certain products for Mylan, as described in the Manufacturing Agreement, at prices that reflect current market conditions for such products and include an agreed upon mark-up on our costs. On May 1, 2021, the Manufacturing Agreement was assigned by Mylan to Nurya Brands, Inc. (“Nurya”) in connection with Nurya’s acquisitions of certain assets from Mylan, including the Cold-EEZE® brand and product line. Unless terminated sooner by the parties, the Manufacturing Agreement was to remain in effect until March 29, 2023 and is currently being negotiated for renewal. Thereafter, the Manufacturing Agreement could be renewed by Nurya for up to four successive one-year periods by providing notice of its intent to renew not less than 90 days prior to the expiration of the then-current term. On November 15, 2022, the Company was notified by Nurya of its election to renew the Manufacturing agreement for one year. As a result, the Manufacturing Agreement remained in effect until March 29, 2024 and is currently in negotiation of extension. License Agreements Linebacker LB1 and LB2 In July 19, 2022, the Company through its wholly-owned subsidiary ProPhase BioPharma entered into a License Agreement (the “Linebacker License Agreement”) with Global BioLife, Inc. (the “Licensor”), with an effective date of July 18, 2022 (the “Linebacker Effective Date”), pursuant to which it acquired from Licensor a worldwide exclusive right and license under certain patents identified in the Linebacker License Agreement (the “Licensed Patents”) and know-how (collectively, the “Licensed IP”) to exploit any compound covered by the Licensed Patents (the “Licensed Compound”), including Linebacker LB1 and LB2, and any product comprising or containing a Licensed Compound (“Licensed Products”) in the treatment of cancer, inflammatory diseases or symptoms, memory-related syndromes, diseases or symptoms including dementia and Alzheimer’s Disease (the “Field”). Under the terms of the Linebacker License Agreement, the Licensor reserves the right, solely for itself and for GRDG Sciences, LLC (“GRDG”) to use the Licensed Compound and Licensed IP solely for research purposes inside the Field and for any purpose outside the Field. Subject to certain conditions set forth in the Linebacker License Agreement, the Company may grant sublicenses (including the right to grant further sublicenses) to its rights under the Linebacker License Agreement to any of its affiliates or any third party with the prior written consent of Licensor, which consent may not be unreasonably withheld. Either party to the Linebacker License Agreement may assign its rights under the Linebacker License Agreement (i) in connection with the sale or transfer of all or substantially all of its assets to a third party, (b) in the event of a merger or consolidation with a third party or (iii) to an affiliate; in each case contingent upon the assignee assuming in writing all of the obligations of its assignor under the Linebacker License Agreement. Under the terms of Linebacker License Agreement, the Company is required to pay to Licensor a one-time upfront license fee of $50,000 within ten days of the Linebacker Effective Date and must pay an additional $900,000 following the achievement of a first Phase 3 study which may be required by United States Food and Drug Administration for the first Licensed Product and an additional $1.0 million upon the receipt of regulatory approval of a New Drug Application for the first Licensed Product. During the term of the Linebacker License Agreement, the Company is also required to pay to Licensor 3% royalties on Net Revenue (as defined in the Linebacker License Agreement) of each Licensed Product, but no less than the minimum royalty of $250,000 of Net Revenue per year minus any royalty payments for any required third party licenses. In connection with the Linebacker License Agreement, the Company has incurred minimal costs for the three months ended March 31, 2024 and 2023 in general and administrative expenses that are included in the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). No clinical studies have begun under this agreement. Equivir In March 2023, we commenced patient enrollment in a randomized, placebo-controlled clinical trial of Equivir to evaluate its effect on upper respiratory tract infections. Vedic Lifesciences (“Vedic”), a leading clinical research organization, is contracted to conduct the combination prophylactic and therapeutic study, which is being conducted at eight sites. Vedic produced interim results in February of 2024 which showed enough data to continue the trial to completion. The trial is expected to be completed by the end of the forth quarter 2024. BE-Smart Esophageal Pre-Cancer Diagnostics Screening Test In March 2023, and in connection with the asset acquisition of Stella, the Company announced a collaboration for the continued development of its BE-Smart Esophageal Pre-Cancer diagnostic screening test. The Company is pursuing initial commercialization of the BE-Smart test as an LDT (Laboratory Developed Test) and RUO (Research Use Only) for the third quarter of 2025 with full commercialization backed by insurance expected by the third quarter of 2025. In connection with the license agreement relating to BE-Smart License Agreement, the Company has incurred approximately $0.2 million in general and administrative expenses that are included in the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) for the three months ended March 31, 2024 and 2023.. No clinical studies have begun under this agreement. Litigation In the normal course of our business, we may be named as a defendant in legal proceedings. It is our policy to vigorously defend litigation or to enter into a reasonable settlement where management deems it appropriate.
