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 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

ProPhase Labs, Inc. and Subsidiaries

Notes to Condensed Consolidated Financial Statements

(unaudited)

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 months ended March 31, 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.

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

ProPhase Labs, Inc. and Subsidiaries

(unaudited)

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, 2023

U.S. government obligations	$	—	$	1,451	$	—	$	1,451

Marketable equity securities	—		—		—		—
	$	5,496	$	2,832	$	—	$	8,328

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

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

ProPhase Labs, Inc. and Subsidiaries

Notes to Condensed Consolidated Financial Statements

(unaudited)

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 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.

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 three months ended March 31, 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.

We will recognize an aggregate of approximately $4.7 million of remaining share-based compensation expense related to outstanding stock options over a weighted average period of 3.9 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 March 31, 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 March 31, 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 three months ended March 31, 2023 is 1.69% and it is primarily driven by federal tax at 21%, state taxes at 10.13%, offset by permanent differences, the R&D credit and state deferred tax benefits.

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.

Note 12 - Subsequent Events

On January 30, 2023, the Administration announced that effective May 11, 2023, the federal Public Health Emergency (“PHE”) 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.

On April 4, 2023, the Company granted, in the aggregate, 550,000 stock options to its CEO and CFO under the 2022 Plan with an exercise price of $9.00. The options vest over a 5-year period in equal annual installments. The estimated fair value of these options at the date of grant was $2.7 million, which will be expensed over the vesting term.

On April 6, 2023, the Company issued 250,000 five year warrants to a consultant that vested at the time of grant and an exercise price of $9.00. The estimated fair value of these options at the date of grant were $1.4 million, which will be expensed over the term of the consulting agreement.

On April 7, 2023, the Company replaced, 250,000 stock options to an employee under the 2022 Plan with an exercise price of $10.00, The options vest 25% on the date of grant with the remaining 75% vesting over a 3-year period in equal annual installments. The estimated fair value of these options at the date of grant was $1.5 million, which will be expensed over the vesting term. The Company will recognize the incremental fair value resulting from the modification of these options.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis should be read in conjunction with our interim unaudited condensed consolidated financial statements and related notes included in this Quarterly Report on Form 10-Q (“Quarterly Report”) and the audited financial statements and notes thereto as of and for the year ended December 31, 2021 and the related Management’s Discussion and Analysis of Financial Condition and Results of Operations, both of which are contained in our Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 29, 2023 (the “2022 Annual Report”).

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 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.

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 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 March 31, 2023 as Compared to the Three Months Ended March 31, 2022

For the three months ended March 31, 2023, net revenue was $19.3 million as compared to $47.5 million for the three months ended March 31, 2022. The decrease in net revenue was the result of a $30.4 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 377,000 tests in the first quarter of 2022 to 120,000 tests in the first quarter of 2023, of which 69.0% and 0% were reimbursed by the HRSA uninsured program, respectively. The average variable consideration received was $121.03 per adjudicated test in the first quarter of 2023 compared to $120.14 per adjudicated test in the first quarter of 2022.

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. Cost of revenues for the three months ended March 31, 2022 were $18.9 million, comprised of $16.7 million for diagnostic services and $2.2 million for consumer products.

We realized a gross profit of $10.5 million for the three months ended March 31, 2023 as compared to $28.7 million for the three months ended March 31, 2022. The decrease of $18.2 million was comprised of a decrease of $18.9 million in diagnostic services, partially offset by an increase of $0.8 million in consumer products. For the three months ended March 31, 2023 and 2022 we realized an overall gross margin of 54.5% and 60.3%, respectively. Gross margin for diagnostic services was 64.0% and 62.8% in the 2023 and 2022 comparable periods, respectively. The increase in gross margin was principally due to (i) increased efficiencies in our lab processing, (ii) a decrease in sample collection costs and (iii) a decrease in cost of test materials. Gross margin for consumer products was 25.5% and 17.8% in the 2023 and 2022 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, 2023 were $1.2 million compared to $4.7 million for the three months ended March 31, 2022. The decrease of $3.5 million was due to decreased COVID-19 testing volumes in 2023 compared to the 2022 period as a result of the Omicron variant, which emerged in late 2021.

General and administration expenses for the three months ended March 31, 2023 were $8.3 million as compared to $7.8 million for the three months ended March 31, 2022. The increase of $0.5 million in general and administration expenses was principally related to an increase in personnel expenses and professional fees associated with our diagnostic services business.

Research and development costs for the three months ended March 31, 2023 were $144,000 as compared to $35,000 for the three months ended March 31, 2022. The increase in research and development costs for the three months ended March 31, 2023 as compared to the three months ended March 31, 2022 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, 2023 and 2022 was $11,000 and $73,000, respectively. The decrease in interest income for the three months ended March 31, 2023 as compared to the three months ended March 31, 2022 was principally due to the lower account balance of our investment account that bears interest.

Interest expense for the three months ended March 31, 2023 was $215,000 compared to $233,000 for the three months ended March 31, 2022. The decrease in interest expense for the three months ended March 31, 2023 as compared to the three months ended March 31, 2022 was principally due to the repayment of notes in the third quarter of 2022.

As a result of the effects described above, net income for the three months ended March 31, 2023 was $0.6 million, or $0.03 per share, as compared to $12.5 million, or $0.81 per share, for the three months ended March 31, 2022. Diluted earnings per share for the three months ended March 31, 2023 and 2022 were $0.03 and $0.68, 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.

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, 2023		March 31, 2022
GAAP net income (1)	$	550	$	12,494
Interest, net	204		160
Income tax expense	14		—
Depreciation and amortization	1,292		1,250
EBITDA	2,060		13,904
Share-based compensation expense	947		482
Non-cash rent expense (2)	6		10
Bad debt expense	74		250
Adjusted EBITDA	$	3,087	$	14,646

(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, 2023 were $9.6 million as compared to $9.1 million at December 31, 2022. Our working capital was 42.8 million and $44.8 million as of March 31, 2023 and December 31, 2022, respectively. The increase of $0.5 million in our cash and cash equivalents for the three months ended March 31, 2023 was principally due to the proceeds from the sale of marketable debt securities of $1.3 million, proceeds issuance of notes payable of $7.6 million, and $0.5 million cash provided by operating activities, offset by (i) the asset purchase of Stella of $2.9 million, (ii) repurchase of common shares for payment of statutory taxes due on cashless exercise of options for $5.4 million, (iii) repurchase of common shares for $0.5 million and (iii) capital expenditures of $0.5 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 the diagnostic business and the Company’s focus thus far on COVID-19 testing, there are inherent uncertainties associated with managements’ business plan and cash flow projections, particularly if the Company is unable to grow its diagnostic testing business beyond COVID-19 testing services.

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 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 their ability 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 (the “CARES Act”) was enacted, providing for reimbursement to healthcare providers for COVID-19 tests provided to uninsured individuals, subject to continued available funding. Approximately 0% and 69.0% of our diagnostic services revenue for the three months ended March 31, 2023 and 2022, respectively, was generated from this program for the uninsured. On March 22, 2022, the Health Resources & Services Administration (“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 (“PHE”) 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 March 31, 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. 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.

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, 2021.

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, 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 March 31, 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. We are not presently a party to any material litigation.

The Company’s 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. The Company believes the lawsuit and the allegations contained therein are without merit and intends to 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 March29, 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. However, we may disclose changes to such factors or disclose additional factors from time to time in our future filings with the SEC.

(“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 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.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

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 months ended March 31, 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.

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, 2023
	Level 1		Level 2		Level 3		Total
U.S. government obligations	$	—	$	1,451	$	—	$	1,451
Corporate obligations	4,395		100		—		4,495
	$	4,395	$	1,551	$	—	$	5,946

	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
Marketable equity securities	—		—		—		—
	$	5,496	$	2,832	$	—	$	8,328

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

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 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.

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 three months ended March 31, 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.

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 March 31, 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 March 31, 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 three months ended March 31, 2023 is 1.69% and it is primarily driven by federal tax at 21%, state taxes at 10.13%, offset by permanent differences, the R&D credit and state deferred tax benefits.

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.

Earnings Per Share

3 Months Ended

Mar. 31, 2023

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):

	For the three months ended
	March 31, 2023		March 31, 2022

Subsequent Events

On January 30, 2023, the Administration announced that effective May 11, 2023, the federal Public Health Emergency (“PHE”) 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.

On April 4, 2023, the Company granted, in the aggregate, 550,000 stock options to its CEO and CFO under the 2022 Plan with an exercise price of $9.00. The options vest over a 5-year period in equal annual installments. The estimated fair value of these options at the date of grant was $2.7 million, which will be expensed over the vesting term.

On April 6, 2023, the Company issued 250,000 five year warrants to a consultant that vested at the time of grant and an exercise price of $9.00. The estimated fair value of these options at the date of grant were $1.4 million, which will be expensed over the term of the consulting agreement.

On April 7, 2023, the Company replaced, 250,000 stock options to an employee under the 2022 Plan with an exercise price of $10.00, The options vest 25% on the date of grant with the remaining 75% vesting over a 3-year period in equal annual installments. The estimated fair value of these options at the date of grant was $1.5 million, which will be expensed over the vesting term. The Company will recognize the incremental fair value resulting from the modification of these options.

Summary of Significant Accounting Policies (Policies)

Accounting Policies [Abstract]

Basis of Presentation

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 months ended March 31, 2023 are not necessarily indicative of operating results that may be achieved over the course of the full year.

Use of Estimates

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

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.

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, 2023
	Level 1		Level 2		Level 3		Total
U.S. government obligations	$	—	$	1,451	$	—	$	1,451
Corporate obligations	4,395		100		—		4,495
	$	4,395	$	1,551	$	—	$	5,946

U.S. government obligations	$	—	$	1,478	$	—	$	1,478

Marketable equity securities	—		—		—		—
	$	5,496	$	2,832	$	—	$	8,328

There were no transfers of marketable debt securities between Levels 1, 2 or 3 for the three months ended March 31, 2023 and 2022.

Goodwill

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

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

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

Recently Issued Accounting Standards, AdoptedOn 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.
