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. We currently 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 OTC consumer healthcare products and dietary supplements in the United States. However, commencing in December 2020, we also began offering COVID-19 and prepared to validate other Respiratory Pathogen Panel (“RPP”) molecular tests through our diagnostic services 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 Clinical Laboratory Improvement Amendments (“CLIA”) certified laboratories including polymerase chain reaction (“PCR”) testing for COVID-19. Critical to COVID-19 testing, we provide fast turnaround times for results. We also offer rapid antigen testing for COVID-19. On October 23, 2020, we acquired Confucius Plaza Medical Laboratory Corp. (“CPM”), which included a non-operating but certified 4,000 square foot CLIA accredited laboratory located in Old Bridge, New Jersey. 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. (“Nebula”), a privately owned personal genomics company, through our new wholly owned subsidiary, ProPhase Precision Medicine, Inc. (“ProPhase Precision”) (see Note 3, Business Acquisitions). ProPhase Precision 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 (dietary supplement) and Equivir G (Rx). In July 2022, PBIO announced a second licensing agreement for two small molecule PIM kinase inhibitors, Linebacker LB-1 and LB-2, with plans to pursue development and commercialization of LB-1 as a cancer co-therapy.

In January 2023, the Company 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.

We also develop and market dietary supplements under the TK Supplements® brand.

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 for interim financial statements and the rules of the Securities and Exchange Commission (“SEC”) applicable to interim financial statements, and therefore do not include all disclosures that might normally be required for financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). 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, 2022. 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 and nine months ended September 30, 2023 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 provision for uncollectible receivables 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 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.

Following is a description of the valuation methodologies used for assets measured at fair value. There have been no changes in the methodologies used at September 30, 2023 and December 31, 2022.

Corporate bonds: Valued using pricing model maximizing the use of observable inputs for similar securities. This includes basing value on yields currently available on comparable securities of issuers with similar credit ratings.

U.S. government securities: Valued using pricing models maximizing the use of observable inputs for similar securities.

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 September 30, 2023
	Level 1		Level 2		Level 3		Total
Corporate obligations	$	—	$	2,565	$	—	$	2,565
	$	—	$	2,565	$	—	$	2,565


	As of December 31, 2022
	Level 1		Level 2		Level 3		Total
U.S. government obligations	$	—	$	1,478	$	—	$	1,478
Corporate obligations	5,496		1,354		—		6,850
	$	5,496	$	2,832	$	—	$	8,328

There were no transfers of marketable debt securities between Levels 1, 2 or 3 for the three and nine months ended September 30, 2023 and 2022.

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 and nine months ended September 30, 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

The Company recognizes revenues in accordance with FASB 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.

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, Adopted

On January 1, 2023, the Company adopted Accounting Standards Update ("ASU") 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”) ASU 2016-13 requires an impairment model (known as the current expected credit loss (“CECL”) model) that is based on expected losses rather than incurred losses. Under the new guidance, each reporting entity should estimate an allowance for expected credit losses, which is intended to result in more timely recognition of losses. This model replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost, accounts receivable and available for sale debt securities and applies to some off-balance sheet credit exposures. In February 2020, the FASB issued ASU 2020-02, Financial Instruments - Credit Losses (Topic 326), which amends the effective date of the original pronouncement for smaller reporting companies. ASU 2016-13 and its amendments will be effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2022. The adoption of ASU 2016-13 did not have a material impact on the Company's consolidated financial statements.

In August 2023, the FASB issued ASU 2023-05, "Business Combinations - Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement." The new guidance applies to the formation of a joint venture and requires a joint venture to initially measure all contributions received upon its formation at fair value. The guidance is intended to reduce diversity in practice and is applicable to joint venture entities with a formation date on or after January 1, 2025 on a prospective basis. The Company currently does not have any transactions that fall under the scope of ASU 2023-05; therefore, the adoption of ASU 2023-05 is not expected to have an impact on the Company's consolidated financial statements.

Note 3 - 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 during the nine months ended September 30, 2023.

In addition to the consideration paid at closing, the Company will issue shares of common stock valued at $2.0 million (the “Milestone Stock”) to the Stella Sellers upon a Commercialization Event (as defined in the Stella Purchase Agreement). The Milestone Stock was recorded at closing as a non-current liability at its fair value of $2.0 million and will be marked to market until settlement through other income or expense in the consolidated statements of operations. 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 FASB 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.

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 September 30, 2023 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, 2022. The decrease in deferred tax assets with a corresponding decrease in valuation allowance against those assets as of September 30, 2023 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 nine months ended September 30, 2023 is 27.88% and it is primarily driven by federal tax at 21%, state taxes at 2.11%, offset by permanent differences, the R&D credit and state deferred tax benefits.

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.

Note 9 – Leases

Operating Leases

On October 23, 2020, we completed the acquisition of CPM, which included the acquisition of a 4,000 square foot CLIA accredited laboratory located in Old Bridge, New Jersey, which was owned by CPM (which is now known as ProPhase Diagnostics NJ, Inc.). The lease was renewed in February 2023, for an additional 36 months until February 2026. The monthly base rent remains the same at $5,500 per month. The lease renewal resulted in the recognition of an additional right-of-use asset and operating lease liability of $170,000, respectively during the nine months ended September 30, 2023.

New York Second Floor Lease

On December 8, 2020, the Company entered into a Lease Agreement (the “NY Second Floor Lease”) with BRG Office L.L.C. and Unit 2 Associates L.L.C. (the “Landlord”), pursuant to which the Company leases certain premises located on the second floor (the “Second Floor Leased Premises”) of 711 Stewart Avenue, Garden City, New York (the “Building”). The Second Floor Leased Premises serve as the Company’s second location and corporate headquarters, offering a wide range of laboratory testing services for diagnosis, screening and evaluation of diseases, including COVID-19 and Respiratory Pathogen Panel Molecular tests.

On June 10, 2022, we entered into a First Amendment to the NY Second Floor Lease (the “Second Floor Lease Amendment”). The Second Floor Lease Amendment amends the NY Second Floor Lease to provide that any uncured default by the Company or any of its affiliate under the NY First Floor Lease (defined below) will constitute a default by the Company under the NY Second Floor Lease.

New York First Floor Lease

On June 10, 2022, the Company entered into a second Lease Agreement (the “NY First Floor Lease”) with Landlord, pursuant to which the Company leases approximately 4,516 sq. feet located on the first floor (the “NY First Floor Leased Premises”) of the Building. As described above, the Company currently leases space on the second floor of the Building. The First Floor Leased Premises will be used to expand the Company’s in-house lab capabilities to include traditional clinical testing across multiple specialty areas and Next Generation Sequencing (NGS) to perform Whole Genome Sequencing (WGS) and an array of genetic diagnostic test offerings for both clinical and research purposes.

The NY First Floor Lease became effective as of June 10, 2022 and will commence upon the date of the Landlord’s substantial completion of certain improvements to the NY First Floor Leased Premises (the “First Floor Commencement Date”), as set forth in the NY First Floor Lease, targeted to be approximately five months from the execution of the NY First Floor Lease. The initial term of the NY First Floor Lease will expire on July 15, 2031, unless sooner terminated as provided in the NY First Floor Lease. During the nine months ended September 30, 2023, the Company recognized additional $0.8 million right-of-use asset and operating lease liability for the NY First Floor Lease.

At September 30, 2023 and December 31, 2022, the Company had operating lease liabilities for the New York and New Jersey leases of approximately $5.3 million and $4.6 million, respectively, and and right of use assets of approximately $4.7 million and $4.1 million, respectively, which were included in the condensed consolidated balance sheet.

Finance Leases

On April 19, 2023, the Company entered into a master lease agreement for a laboratory equipment (the "First Equipment Lease") with a vendor. The First Equipment Lease has a 5-year term and is recognized as a finance lease under ASC 842. The present value of the minimum future obligations of $1.5 million was calculated based on an interest rate of 8.0%, which was recognized in finance lease liabilities in the condensed consolidated balance sheet.

On July 21, 2023, the Company entered into a master lease agreement for a laboratory equipment (the "Second Equipment Lease") with a vendor. The Second Equipment Lease has a 4-year term and is recognized as a finance lease under ASC 842. The present value of the minimum future obligations of $5.1 million was calculated based on an interest rate of 7.4%, which was recognized in finance lease liabilities in the condensed consolidated balance sheet.

On September 26, 2023, the Company entered into a master lease agreement for a laboratory equipment (the "Third Equipment Lease") with a vendor. The Third Equipment Lease has a 3-year term starting on the commencement date. The commencement date is when the equipment is shipped and installed, then the Company will provide Final Acceptance Certificate to the vendor. As of September 30, 2023, the commencement date was not established, therefore, there was no fixed assets or finance lease liability recognized in the condensed consolidated balance sheet.

Depreciation and interest expense related to the Equipment Lease was $440,000 and $510,000 for the three and nine months ended September 30, 2023, respectively.

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.

The following is a reconciliation of the weighted average number of common shares outstanding used in calculating basic and diluted net loss per share (in thousands):


	For the three months ended				For the nine months ended

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 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 Clinical Labotary Improvement Amendments (“CLIA”) certified laboratories including polymerase chain reaction (“PCR”) 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. (“CPM”), 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. (“Nebula”), a privately owned personal genomics company, through our new wholly owned subsidiary, ProPhase Precision Medicine Inc. (“ProPhase Precision”). ProPhase Precision 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 PIM 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.

Table of Contents

Our diagnostic service business is and will continue to be impacted by the level of demand for COVID-19 and other diagnostic testing, how long this demand persists, the price we are able to receive for performing our testing services, our ability to collect payment or reimbursement for our testing services, as well as the availability of COVID-19 testing from other laboratories and the period of time for which we are able to serve as an authorized laboratory offering COVID-19 testing under various Emergency Use Authorizations.

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 September 30, 2023 as Compared to the Three Months Ended September 30, 2022

Net revenue for the three months ended September 30, 2023 was $8.4 million as compared to $24.2 million for the three months ended September 30, 2022. The decrease in net revenue was the result of a $18.0 million decrease in net revenue from diagnostic services, partially offset by a $2.2 million increase in consumer products. The decrease in net revenue for diagnostic services was due to decreased COVID-19 testing volumes compared to the 2022 period as a result of the Omicron variant, which emerged in early 2022. Overall diagnostic testing volume decreased from 113,000 tests in the three months ended September 30, 2022 to 13,000 tests in the three months ended September 30, 2023.

Cost of revenues for the three months ended September 30, 2023 was $6.0 million, comprised of $1.8 million for diagnostic services and $4.2 million for consumer products. Cost of revenues for the three months ended September 30, 2022 were $12.2 million, comprised of $8.5 million for diagnostic services and $3.8 million for consumer products. The decrease in cost of revenues for diagnostic services between the two comparable periods was due to the reduction in COVID-19 testing volumes.

We realized a gross profit of $2.3 million for the three months ended September 30, 2023 as compared to $12.0 million for the three months ended September 30, 2022. The decrease of $9.6 million was comprised of a decrease of $11.4 million in diagnostic services, partially offset by an increase of $1.7 million in consumer products. For the three months ended September 30, 2023 and 2022 we realized an overall gross margin of 27.8% and 49.5%, respectively. Gross margin for diagnostic services was 27.8% and 58.9% in the three months ended September 30, 2023 and 2022, respectively. Gross margin for consumer products was 27.8% and (3.2)% in the three months ended September 30, 2023 and 2022, 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 September 30, 2023 were $0.1 million compared to $2.4 million for the three months ended September 30, 2022. The decrease of $2.3 million was due to decreased COVID-19 testing volumes during the three months ended September 30, 2023 compared to the three months ended September 30, 2022 as a result of the Omicron variant, which emerged in early 2022.

Table of Contents

General and administration expenses for the three months ended September 30, 2023 were $8.2 million as compared to $7.5 million for the three months ended September 30, 2022. The increase of $0.7 million in general and administration expenses was principally related to an increase in personnel expenses, marketing and professional fees associated with the Company's strategic initiatives.

Research and development costs for the three months ended September 30, 2023 were $0.4 million as compared to $0.1 million for the three months ended September 30, 2022. The increase in research and development costs for the three months ended September 30, 2023 as compared to the three months ended September 30, 2022 was principally due to increased activities at ProPhase BioPharma. These activities include product research and field testing.

Interest and other income for the three months ended September 30, 2023 was $1,000 as compared to $25,000 for the comparable period in 2022. Interest expense for the three months ended September 30, 2023 was $0.3 million compared to $0.2 million for the three months ended September 30, 2022.

As a result of the effects described above, net loss for the three months ended September 30, 2023 was $(5.1) million, or $(0.30) per share, as compared to a net income of $1.0 million, or $0.06 per share, for the three months ended September 30, 2022. Diluted (loss) earnings per share for the three months ended September 30, 2023 and 2022 were $(0.30) and $0.06, respectively.

Nine Months Ended September 30, 2023 as Compared to the Nine Months Ended September 30, 2022

For the nine months ended September 30, 2023, net revenue was $40.9 million as compared to $100.8 million for the nine months ended September 30, 2022. The decrease in net revenue was the result of a $66.8 million decrease in net revenue from diagnostic services, partially offset by a $6.9 million increase in consumer products. The decrease in net revenue for diagnostic services was due to decreased COVID-19 testing volumes compared to the 2022 period as a result of the Omicron variant, which emerged in early 2022. Overall diagnostic testing volume decreased from 634,000 tests for the nine months ended September 30, 2022 to 259,000 tests in the nine months ended September 30, 2023, of which 54.9% were reimbursed by the HRSA uninsured program for the nine months ended September 30, 2022, and none were reimbursed from the HRSA uninsured program during the nine months ended September 30, 2023.

Cost of revenues for the nine months ended September 30, 2023 were $21.6 million, comprised of $10.8 million for diagnostic services and $10.8 million for consumer products. Cost of revenues for the nine months ended September 30, 2022 were $41.5 million, comprised of $33.6 million for diagnostic services and $7.9 million for consumer products.The decrease in cost of revenues for diagnostic services between the two comparable periods was due to the reduction in COVID-19 testing volumes.

We realized a gross profit of $19.3 million for the nine months ended September 30, 2023 as compared to $59.4 million for the nine months ended September 30, 2022. The decrease of $40.1 million was comprised of a decrease of $44.0 million in diagnostic services, partially offset by an increase of $3.9 million in consumer products. For the nine months ended September 30, 2023 and 2022 we realized an overall gross margin of 47.2% and 58.9%, respectively. Gross margin for diagnostic services was 56.5% and 63.4% in the nine months ended September 30, 2023 and 2022, respectively. Gross margin for consumer products was 32.8% and 14.3% in the nine months ended September 30, 2023 and 2022, 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 nine months ended September 30, 2023 were $1.9 million compared to $8.9 million for the nine months ended September 30, 2022. The decrease of $7.0 million was due to decreased COVID-19 testing volumes in during the nine months ended September 30, 2023 compared to the comparable period in 2022 as a result of the Omicron variant, which emerged in early 2022.

General and administration expenses for the nine months ended September 30, 2023 were $26.5 million as compared to $21.6 million for the nine months ended September 30, 2022. The increase of $4.9 million in general and administration expenses was principally related to an increase in personnel expenses, marketing and professional fees associated with the Company's strategic initiatives.

Research and development costs for the nine months ended September 30, 2023 were $1.1 million as compared to $174,000 for the nine months ended September 30, 2022. The increase in research and development costs for the nine three

months ended September 30, 2023 as compared to the nine months ended September 30, 2022 was principally due to increased activities at ProPhase BioPharma. These activities include product research and field testing.

Interest and other income for the nine months ended September 30, 2023 was $39,000 as compared to $123,000 for the comparable period in 2022. The decrease in interest income for the nine months ended September 30, 2023 as compared to the nine months ended September 30, 2022 was principally due to the lower account balance of our investment account that bears interest.

Interest expense for the nine months ended September 30, 2023 was $781,000 compared to $635,000 for the nine months ended September 30, 2022. The increase in interest expense for the nine months ended September 30, 2023 as compared to the nine months ended September 30, 2022 was principally due to higher balance of our outstanding debt that bears interest.

As a result of the effects described above, net loss for the nine months ended September 30, 2023 was $(8.0) million, or $(0.47) per share, as compared to a net income of $20.9 million, or $1.33 per share, for the nine months ended September 30, 2022. Diluted (loss) earnings per share for the nine months ended September 30, 2023 and 2022 were $(0.47) and $1.10, respectively.

Non-GAAP Financial Measures and Reconciliation

In an effort to provide investors with additional information regarding our results of operations as determined by generally accepted accounting principles 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				For the nine months ended

Bad debt expense	—		—		74		250
Adjusted EBITDA	$	(2,525)	$	6,296	$	(1,775)	$	35,471

(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, cash equivalents and marketable securities available for sale as of September 30, 2023 were $3.3 million as compared to $17.4 million at December 31, 2022. Our working capital was $33.4 million and $44.8 million as of September 30, 2023 and December 31, 2022, respectively. The decrease of $14.2 million in our cash and cash equivalents for the nine months ended September 30, 2023 was principally due to (a) the proceeds from the sale of marketable debt securities of $3.8 million, (b) the proceeds from the maturities of marketable debt securities of $4.2 million, (c) the proceeds for issuance of notes payable of $7.6 million, and (d) the proceeds from warrant exercise of $1.2 million, offset by (i) $11.1 million cash used in operating activities, (ii) the asset purchase of Stella of $2.9 million, (iii) repurchase of common shares for payment of statutory taxes due on cashless exercise of options for $5.4 million, (iv) repurchase of common shares for $0.6 million, (v) purchase marketable debt securities of $3.8 million, and (vi) capital expenditures of $1.8 million.

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 lines of business 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 and the established relationships with our investment banks will enable us to continue to meet our obligations and fund ongoing operations.

COVID-19

The COVID-19 pandemic has not had a material adverse impact on our business to date. We experienced higher than normal net revenue for the year ended December 31, 2021 and nine months ended September 30, 2022, primarily as a

Table of Contents

result of revenue from our diagnostic services business, which offers COVID-19 testing. There can be no assurance that demand for our COVID-19 testing services will continue to exist in the future due to the widespread and effective vaccination of a majority of Americans against COVID-19 and successful containment efforts. If there is no demand for our COVID-19 testing services, and we are unable to generate sufficient profits from other RPP Molecular tests, our business could be materially adversely affected.

There are still numerous uncertainties associated with the COVID-19 pandemic, including the ability of vaccines and other protective measures to protect against new strains of the virus, people’s willingness to receive a vaccine, possible resurgences of the coronavirus and/or new strains of the virus, the extent and duration of protective and preventative measures that may be adopted by local, state and/or the federal government in the future as a result of future outbreaks, including business closures, the ongoing impact of COVID-19 on the U.S. and world economy and consumer confidence, and various other uncertainties all of which could negatively impact our Company as a whole.

The COVID-19 pandemic has had a negative impact on the global capital markets and economies worldwide and could ultimately have a material adverse impact on our ability to raise capital needed to develop and commercialize products.

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. Approximately 54.9% of our diagnostic services revenue for the nine months ended September 30, 2022, was generated from this program for the uninsured. None of our diagnostic revenues for the nine months ended September 30, 2023 was generated from this program for the uninsured. On March 22, 2022, the HRSA 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, emergency funding has not been allocated to the HRSA uninsured program. We continue to perform testing for uninsured persons and are incurring the accompanying costs.

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. While the Company is still assessing the impact this may have on our operations and financial performance, it could impact our ability to collect insurance reimbursements and could negatively impact revenues in future periods.

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 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).

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.

As of September 30, 2023, we have not sold any shares under the Sales Agreement.

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 has not had a material effect on our business.

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 provision for bad debt 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 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 doubtful accounts. Allowances for doubtful accounts are based upon our judgment regarding collectability. On a periodic basis, we evaluate our receivables and establish an allowance for doubtful accounts, 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.

Table of Contents

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

On January 1, 2023, the Company adopted ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”) ASU 2016-13 requires an impairment model (known as the current expected credit loss (“CECL”) model) that is based on expected losses rather than incurred losses. Under the new guidance, each reporting entity should estimate an allowance for expected credit losses, which is intended to result in more timely recognition of losses. This model replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost, accounts receivable and available for sale debt securities and applies to some off-balance sheet credit exposures. In February 2020, the FASB issued ASU 2020-02, Financial Instruments - Credit Losses (Topic 326), which amends the effective date of the original pronouncement for smaller reporting companies. ASU 2016-13 and its amendments will be effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2022. The adoption of ASU 2016-13 did not have a material impact on the Company's 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

Table of Contents

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, 2022.

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 September 30, 2023. 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 September 30, 2023.

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. There are no material updates to the matters previously disclosed in Item 1, "Legal Proceedings" to our Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2023, except as provided below. We are not presently a party to any other material litigation.

Our wholly-owned subsidiary, TK Supplements, Inc., is 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 alleges that TK Supplements falsely advertised its Legendz XL male enhancement supplement in violation of California’s Consumer Legal Remedies Act. The plaintiff is seeking certification of a class of California purchasers; actual, statutory and punitive damages; an award of attorneys’ fees and costs; and all other relief at law or in equity as may be proper. TK Supplements, Inc., filed a demurrer and motion to strike the plaintiff’s complaint, which resulted in the plaintiff filing an amended complaint making similar allegations. We believe the lawsuit and the allegations contained therein are without merit. We intend to file another demurrer and vigorously defend against the litigation.

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, 2023. 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, 2023, except as provided below. In addition, we may disclose changes to such factors or disclose additional factors from time to time in our future filings with the SEC. 

Billing and collections processing for our diagnostic tests is complex and time-consuming, and any delay in transmitting and collecting claims could have an adverse effect on our revenue.

Billing for our diagnostic tests is complex, time-consuming and expensive. Depending on the billing arrangement and applicable law, we may bill different parties for our tests. This includes billing customers directly, as in the case of our hospital and other medical institution customers, as well as billing through Medicare, Medicaid, insurance companies and patients, all of which may have different billing requirements. We may face increased risk in our collection efforts due to the complexities of these billing requirements, including long collection cycles and lower collection rates, which could adversely affect our business, results of operations and financial condition.

Several factors make this billing process complex, including:

•contractual restrictions in our customer contracts that may limit our ability to utilize certain third-party billing service providers;

•differences between the list price for our tests and the reimbursement rates of payors;

•compliance with complex federal and state regulations related to billing government healthcare programs, including Medicare and Medicaid;

•disputes among payors as to which party is responsible for payment;

•disputes with payors regarding the amount due;

•differences in coverage among payors and the effect of patient co-payments or co-insurance;

•differences in information and billing requirements among payors;

•incorrect or missing billing or insurance information; and

•the resources required to manage the billing and claims appeals process.

In addition, the expiration of the federal Public Health Emergency on May 11, 2023 changed regulatory guidelines around COVID-19 testing including billing codes and reimbursement rates of in and out of network laboratories.

Table of Contents

We have developed internal systems and procedures to handle these billing and collections functions, but we must continue to make significant efforts and expend substantial resources to further develop our systems and procedures to handle these aspects of our business, which could become increasingly important as we focus on increasing test volumes and establishing coverage and reimbursement policies with third-party payors. As a result, these billing complexities, along with the related uncertainty in obtaining payment for our tests, could negatively affect our revenue and cash flow, our ability to achieve or sustain profitability and the consistency and comparability of our results of operations. In addition, if claims for our tests are not submitted to payors on a timely basis, if we are required to switch to a different provider to handle our processing and collections functions, our revenue and our business could be adversely affected.

Failure to accurately bill for testing services, or to comply with applicable laws relating to government health care programs, could have a material adverse effect on our business.

Billing for diagnostic services is complex and subject to extensive and non-uniform rules and administrative requirements. Depending on the billing arrangement and applicable law, we bill various payers, such as patients, insurance companies, government groups, Medicare and Medicaid. Effective November 2021, billing for diagnostic services is performed internally by our billing department. Failure to accurately bill for our services could have a material adverse effect on our business. For example, certain billing claims for our diagnostic services are taking longer to process and complete because of incorrect patient or insurance information. We have engaged a third-party biller to assist with such claims; however, there is no guarantee that we and our third-party biller will be successful in collecting payments from the services we provided.

In addition, failure to comply with applicable laws relating to billing government health care programs may result in various consequences, including the return of overpayments, civil and criminal fines and penalties, exclusion from participation in government health care programs and the loss of various licenses, certificates and authorizations necessary to operate our business, as well as incur additional liabilities from third-party claims, all of which could have a material adverse effect on our business. Certain violations of these laws may also provide the basis for a civil remedy under the federal False Claims Act, including fines and damages of up to three times the amount claimed. The qui tam provisions of the federal False Claims Act and similar provisions in certain state false claims acts allow private individuals to bring lawsuits against health care companies on behalf of the government. Although we believe we are compliant, in all material respects, with applicable laws and regulations, there can be no assurance that a regulatory agency or tribunal would not reach a different conclusion. The federal and state governments have substantial leverage in negotiating settlements since the amount of potential damages and fines far exceeds the rates at which services will be reimbursed, and the government has the remedy of excluding a non-compliant provider from participation in the Medicare and Medicaid programs. We expect that federal and state governments continue aggressive enforcement efforts against perceived health care fraud. Legislative provisions relating to health care fraud and abuse provide government enforcement personnel with substantial funding, powers, penalties and remedies to pursue suspected cases of fraud and abuse.

Our ability to achieve or sustain profitability depends on our collection of payment for the tests we deliver, which we may not be able to do successfully.

Our customer base for our COVID-19 and influenza tests is principally comprised of governmental bodies, municipalities, and large corporations who pay us directly or through third-party payors. 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. On March 22, 2022, HRSA uninsured program stopped accepting claims for COVID-19 testing and treatment due to the 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, emergency funding has not been allocated to the HRSA uninsured program. We continue to perform limited testing for uninsured persons and are incurring the accompanying costs. Approximately 31.5% and 0% of our diagnostic services revenue for the year ended December 31, 2022 and for the nine months ended September 30, 2023, respectively, was generated from this program for the uninsured.

Further, healthcare policy changes that influence the way healthcare is financed or other changes in the market that impact payment rates by institutional or non-institutional customers could also affect our collection rates. If we are unable to convince customers of the value and benefit provided by our tests, these customers may slow, or stop altogether, their purchases of these tests. Our collection risks also include the potential for default or bankruptcy by the party responsible for payment and other risks associated with payment collection generally. Any inability to maintain our past payment collection levels could cause our revenue and ability to achieve profitability to decline and adversely affect our business, prospects and financial condition.

(“ProPhase Diagnostics”), which was formed on October 9, 2020, offers a broad array of clinical diagnostic and testing services at its Clinical Laboratory Improvement Amendments (“CLIA”) certified laboratories including polymerase chain reaction (“PCR”) testing for COVID-19. Critical to COVID-19 testing, we provide fast turnaround times for results. We also offer rapid antigen testing for COVID-19. On October 23, 2020, we acquired Confucius Plaza Medical Laboratory Corp. (“CPM”), which included a non-operating but certified 4,000 square foot CLIA accredited laboratory located in Old Bridge, New Jersey. 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. (“Nebula”), a privately owned personal genomics company, through our new wholly owned subsidiary, ProPhase Precision Medicine, Inc. (“ProPhase Precision”) (see Note 3, Business Acquisitions). ProPhase Precision 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 (dietary supplement) and Equivir G (Rx). In July 2022, PBIO announced a second licensing agreement for two small molecule PIM kinase inhibitors, Linebacker LB-1 and LB-2, with plans to pursue development and commercialization of LB-1 as a cancer co-therapy. In January 2023, the Company 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. We also develop and market dietary supplements under the TK Supplements® brand.

Asset Acquisition	Sep. 30, 2023
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 during the nine months ended September 30, 2023. In addition to the consideration paid at closing, the Company will issue shares of common stock valued at $2.0 million (the “Milestone Stock”) to the Stella Sellers upon a Commercialization Event (as defined in the Stella Purchase Agreement). The Milestone Stock was recorded at closing as a non-current liability at its fair value of $2.0 million and will be marked to market until settlement through other income or expense in the consolidated statements of operations. 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 FASB 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.

The Company has the right to prepay the 2023 Note at any time after the 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 2023 Note has been guaranteed by the Company’s wholly-owned subsidiary, Pharmaloz Manufacturing, Inc. In addition to the 2023 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 FASB ASC 835-30-25, Recognition, and is being accreted over the term of the note payable for financial statement purposes.

Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesWe 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 September 30, 2023 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, 2022. The decrease in deferred tax assets with a corresponding decrease in valuation allowance against those assets as of September 30, 2023 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 nine months ended September 30, 2023 is 27.88% and it is primarily driven by federal tax at 21%, state taxes at 2.11%, offset by permanent differences, the R&D 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. 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 will remain in effect until March 29, 2024. License Agreements Linebacker LB1 and LB2 On July 19, 2022, the Company through its wholly-owned subsidiary ProPhase BioPharma entered into a License Agreement (the “License Agreement”) with Global BioLife, Inc.

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.

Segment Reporting [Abstract]

Segment Information

Segment InformationThe Company has identified two operating segments, diagnostic services and consumer products, based on the manner in which the Company’s CEO as CODM assesses performance and allocates resources across the organization. The operating segments are organized in a manner that depicts the difference in revenue generating synergies that include the separate processes, profit generation and growth of each segment. The diagnostic services segment provides COVID-19 diagnostic information services to a broad range of customers in the United States, including health plans, third party payers and government organizations. The consumer products segment is engaged in the research, development, manufacture, distribution, marketing and sale of OTC consumer healthcare products and dietary supplements in the United States and also provides personal genomics products and services. The unallocated corporate expenses mainly included professional fees associated with the public company.

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per ShareBasic 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.

The following is a reconciliation of the weighted average number of common shares outstanding used in calculating basic and diluted net loss per share (in thousands):
