Explanatory Note

Exagen Inc. (the Company) hereby amends its Quarterly Report on Form 10-Q for the quarter ended June 30, 2022, filed with the Securities and Exchange Commission (the SEC) on August 4, 2022 (the Original Quarterly Report), as set forth in this Amendment No. 1 on Form 10-Q/A (the Form 10-Q/A or Amended Quarterly Report), to amend and restate its financial statements and related disclosures as of and for the three and six months ended June 30, 2022.

Restatement Background

On November ~~5, 2021~~13, 2022, management and the audit committee of our board of directors determined that the Company made certain errors in revenue resulting from erroneous and duplicate billings related to changes in billing practices. The errors were due to the inadequate design and implementation and precision of internal controls and procedures to evaluate and monitor the accounting for revenue recognition. As a result, revenue and accounts receivable were overstated and other liabilities was ~~16,164,232.~~understated for the quarter and year to date periods ended June 30, 2022.

In connection with the restatement, the Company has also corrected errors associated with revenue that it determined to be immaterial, both individually and in the aggregate, to the financial statements for the fiscal quarter ended June 30, 2022. A summary of the accounting impacts of these adjustments to the Company's financial statements as of and for the three and six months ended June 30, 2022 is provided in Note 1 "Restatement of Previously Issued Financial Statements," of the Notes to Condensed Financial Statements of this Form 10-Q/A. The effect of these errors was a $1.4 million overstatement of revenue for the three and six months ended June 30, 2022; in addition to, a $0.9 million overstatement of accounts receivable and a $0.5 million understatement of other liabilities as of June 30, 2022.

This Amended Quarterly Report also amends and restates the Company's Management's Discussion and Analysis of Financial Condition and Results of Operations, Risk Factors and other disclosures made in the Original Quarterly Report, as appropriate, to reflect the restatement of the relevant periods.

In accordance with Rule 12b-15 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, the Company is also including with this Amended Quarterly Report currently dated certifications of the Company's principal executive officer and principal financial officer (attached as Exhibits 31.1, 31.2, and 32.1).

Except as discussed above and as further described in Note 1, Note 1A, Note 2 and Note 3 in the Notes to Condensed Financial Statements, the Company has not modified or updated disclosures presented in this Amended Quarterly Report. Accordingly, the Amended Quarterly Report does not reflect events occurring after the Original Quarterly Report or modify or update those disclosures affected by subsequent events. Information not affected by the restatement is unchanged and reflects disclosures made at the time of the filing of the Original Quarterly Report.

In connection with the restatement, the Company has concluded there was a material weakness in its internal control over financial reporting as of June 30, 2022, and its disclosure controls and procedures were not effective. See additional discussion included in Part I, Item 4 of this Amended Quarterly Report.

Notes to Unaudited Interim Condensed Financial Statements

Note 1. Organization

Description of Business

Exagen Inc. (the Company) is dedicated to transforming the care continuum for patients suffering from debilitating and chronic autoimmune diseases by enabling timely differential diagnosis and optimizing therapeutic intervention.

Liquidity

The Company has incurred recurring losses and negative cash flows from operating activities since inception. The Company anticipates that it will continue to incur net losses into the foreseeable future. ~~At September~~As of June 30, ~~2021,~~2022, the Company had cash and cash equivalents of ~~$106.8~~$76.4 million and had an accumulated deficit of ~~$201.1 million.~~$233.1 million (as restated). Since inception, the Company has financed its operations primarily through a combination of equity financings of common stock and private placements of preferred securities, debt financing arrangements, and revenue from sales of the Company's products. Based on the Company's current business plan, management believes that its existing capital resources will be sufficient to fund the Company's obligations for at least twelve months following the issuance of these condensed financial statements.

To execute its business plans, the Company may need additional funding to support its continuing operations and pursue its growth strategy. Until such time as the Company can achieve significant cash flows from operations, if ever, it expects to finance its operations through the sale of its stock, debt financings or other strategic transactions. Although the Company has been successful in raising capital in the past, there is no assurance that it will be successful in obtaining such additional financing on terms acceptable to the Company, if at all. The terms of any financing may adversely affect the holdings or the rights of the Company's stockholders. If the Company is unable to obtain funding, the Company could be forced to delay, reduce or eliminate some or all of its programs, product portfolio expansion plans or commercialization efforts, which could have a material adverse effect on the Company's business, operating results and financial condition and the Company's ability to achieve its intended business objectives.

Impact of COVID-19 Pandemic

In 2020, due to the worldwide COVID-19 pandemic, the Company began to experience a reduction in patient test volumes, delays in patient enrollment in ongoing and planned clinical studies, and delays in the procurement of its testing supplies. The full extent to which the COVID-19 pandemic will directly or indirectly continue to impact the Company's business, results of operations and financial condition, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain or treat COVID-19, including, the success of ongoing vaccination efforts, the emergence and prevalence of variant strains of COVID-19, the institution or reinstitution of shutdowns, "stay-at-home-orders" and other public health measures as well as the related economic impact of these matters on local, regional and international markets.

Note 1A. Restatement of Previously Issued Financial Statements

The Company has restated previously issued financial statements and related disclosures as of and for the three and six months ended June 30, 2022 included in our Quarterly Report on Form 10-Q, filed with the Securities and Exchange Commission (the SEC) on August 4, 2022 (the Original Quarterly Report), in order to correct misstatements resulting from erroneous and duplicate billings included in revenue. The applicable Notes to Condensed Financial Statements were also updated to reflect the restatement.

Impact of Restatement

In November 2022 management determined that the Company made certain errors in revenue resulting from erroneous and duplicate billings related to changes in billing practices. The errors were due to the inadequate

design and implementation and precision of internal controls and procedures to evaluate and monitor the accounting for revenue recognition. As a result, the Company determined that there were material errors in the financial statements that required a restatement of the financial statements for the three and six months ended June 30, 2022 in the Original Quarterly Report. The effect of these errors was a $1.4 million overstatement of revenue for the three and six months ended June 30, 2022; in addition to, a $0.9 million overstatement of accounts receivable and a $0.5 million understatement of other liabilities as of June 30, 2022.

The following tables reflect the impact of the restatement adjustments to the specific line items presented in our previously reported financial statements for the periods indicated. The amounts originally reported were derived from the Original Quarterly Report (in thousands, except per share amounts):

Note 2. Summary of Significant Accounting Policies

Basis of Presentation and Use of Estimates

The accompanying interim condensed balance sheet as of ~~September~~June 30, ~~2021,~~2022, the condensed statements of operations and the condensed statements of stockholders' equity for the three and ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020 and~~2021, cash flows for the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020~~2021 and the related footnote ~~disclosure~~disclosures are unaudited and have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (SEC), and with accounting principles generally accepted in the United States (GAAP) applicable to interim financial statements. In management's opinion, the unaudited interim condensed financial statements have been prepared on the same basis as the audited financial statements and include all normal adjustments, necessary for the fair presentation of the Company's financial position as of ~~September~~June 30, ~~2021~~2022 and its results of operations for the three and ~~nine~~six month periods presented. The results for the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 are not necessarily indicative of the results expected for the full fiscal year or any other interim period. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. These unaudited condensed financial statements should be read in conjunction with the Company’s audited financial statements for the year ended December 31, ~~2020,~~2021, included in its Annual Report on Form 10-K filed with the SEC on March ~~16, 2021.~~22, 2022.

The preparation of the accompanying condensed financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the condensed financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could materially differ from those estimates.

Significant estimates and assumptions made in the accompanying condensed financial statements include, but are not limited to revenue recognition, estimated incremental borrowing rate for the ~~fair value~~determination of ~~financial instruments measured at fair value,~~the Company's operating lease right-of-use (ROU) assets, the recoverability of its long-lived assets (including goodwill) and net deferred tax assets (and related valuation allowance). The Company evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could materially differ from those estimates.

Concentration of Credit Risk and Other Risk and Uncertainties

Financial instruments that potentially subject the Company to credit risk consist principally of cash, cash equivalents, and accounts receivable. Substantially all the Company's cash and cash equivalents are held at one financial institution that management believes is of high credit quality. Such deposits may, at times, exceed federally insured limits.

Significant payors and customers are those which represent more than 10% of the Company's total revenue or accounts receivable balance at each respective balance sheet date. For each significant payor and customer, revenue as a percentage of total revenue and accounts receivable as a percentage of total accounts receivable are as follows:


		Revenue									Revenue

For each of the three months ended ~~September~~June 30, 2022 and 2021, approximately 77% and ~~2020, approximately~~ 81% ~~and 68%~~, respectively, of the Company's revenue was related to the AVISE® CTD test. For the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, approximately 81% and ~~71%~~81%, respectively, of the Company's revenue was related to the AVISE® CTD test.

The Company is dependent on key suppliers for certain laboratory materials. For each of the three months ended ~~September~~June 30, 2022 and 2021, ~~and 2020,~~ approximately ~~95% and 98%, respectively,~~97% of the Company's diagnostic testing supplies were purchased from two suppliers. For the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, approximately 96% and 97%, respectively, of the Company's diagnostic testing supplies were purchased from two suppliers. An interruption in the supply of these materials would impact the Company's ability to perform testing services.

Disaggregation of Revenue

The following table includes the Company's revenues as disaggregated by payor and customer category (in thousands):


											Three Months Ended June 30,				Six Months Ended June 30,

Fair Value Measurements

The carrying value of the Company's cash and cash equivalents approximate fair value due to the short-term nature of these items. ~~Based~~The estimated fair value of the Company's long-term borrowings are determined by Level 2 inputs and is based primarily on quoted market prices for the ~~borrowing rates currently available to the Company for debt with~~same or similar ~~terms and consideration of default and credit risk, the carrying~~issues. The recorded value of the Company's long-term borrowings approximates ~~its~~the current fair value as the interest rate and other terms are that which ~~is considered a Level 2 input.~~are currently available to the Company.

Fair value is defined as the exchange price that would be received for an asset or an exit price paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs.

The fair value hierarchy defines a three-level valuation hierarchy for disclosure of fair value measurements as follows:

Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities;

Level 2 - Inputs other than quoted prices included within Level I that are observable, unadjusted quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities; and

Level 3 - Unobservable inputs that are supported by little or no market activity for the related assets or liabilities.

The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

Cash, Cash Equivalents and Restricted Cash

The Company considers all highly-liquid investments purchased with a remaining maturity date upon acquisition of three months or less to be cash equivalents and are stated at cost, which approximates fair value.

~~In 2016, the~~The Company ~~entered into~~has an arrangement with a financial institution with which it has an existing banking relationship whereby, in exchange for the issuance of corporate credit cards, the Company agreed to obtain a $0.1 million certificate of deposit with this financial institution as collateral for the balances borrowed on these credit cards. The Company has classified the value of this certificate of deposit (including all interest earned thereon) within other assets in the accompanying balance sheets. The Company has the right to terminate the credit card program at any time. Upon termination of the credit card program and repayment of all outstanding balances owed, the Company may redeem the certificate of deposit (and all interest earned thereon).

Cash, cash equivalents and restricted cash presented in the accompanying condensed statements of cash flows consist of the following (in thousands):

Revenue Recognition

Substantially all of the Company's revenue has been derived from sales of its testing products and is primarily comprised of a high volume of relatively low-dollar transactions. The Company primarily markets its testing products to rheumatologists and their physician assistants in the United States. The healthcare professionals who order the Company's testing products and to whom test results are reported are generally not responsible for payment for these products. The parties that pay for these services (each, ~~a payor)~~payors) consist of healthcare insurers, government

payors (primarily Medicare and Medicaid), client payors (i.e., hospitals, other laboratories, etc.), and patient self-pay. The Company's service is a single performance obligation that is completed upon the delivery of test results to the prescribing physician which triggers revenue recognition.

Payors are billed at the Company's list price. Net revenues recognized consist of amounts billed net of allowances for differences between amounts billed and the estimated consideration the Company expects to receive from such payors. The process for estimating revenues and the ultimate collection of accounts receivable involves significant judgment and estimation. The Company follows a standard process, which considers historical denial and collection experience, insurance reimbursement policies and other factors, to estimate allowances and implicit price concessions, recording adjustments in the current period as changes in estimates occur. Further adjustments to the allowances, based on actual receipts, are recorded upon settlement. Included in revenues for the three months ended June 30, 2022 and 2021 was a $1.2 million net revenue decrease and a $0.1 million net revenue increase, respectively, associated with changes in estimated variable consideration related to performance obligations satisfied in previous periods. Such amounts of variable consideration for the six months ended June 30, 2022 and 2021 were $1.6 million and $0.1 million, respectively, of net revenue decreases. The transaction price is estimated using an expected value method on a portfolio basis. The Company's portfolios are grouped per payor (i.e. each individual third-party insurance, Medicare, client payors, patient self-pay, etc.) and per ~~test basis.~~test. Consideration may be constrained and excluded from the transaction price in situations where there is no contractually agreed upon reimbursement coverage or in absence of a predictable pattern and history of collectability with a payor. Accordingly, in such situations revenues are recognized on the basis of actual cash collections. Additionally, from time to time, the Company may issue refunds to payors for overpayments or amounts billed in error. Any refunds are accounted for as reductions in revenues in the statement of operations as an element of variable consideration. The estimated expected refunds are accrued as a liability on the Company’s balance sheet. Additionally, from time to time, the Company may issue refunds to payors for overpayments or amounts billed in error. Any refunds are accounted for as reductions in revenues in the statement of operations as an element of variable consideration. The estimated expected refunds are accrued as a liability on the Company’s balance sheet.

Collection of the Company's net revenues from payors is normally a function of providing complete and correct billing information to the healthcare insurers and generally occurs within 30 to 90 days of billing. Contracts do not contain significant financing components based on the typical period of time between performance of services and collection of consideration.

Janssen Promotion Agreement

In December 2018, the Company entered into a co-promotion agreement (as amended from time to time, the Janssen Agreement) with Janssen Biotech, Inc. (Janssen) to co-promote SIMPONI® in the United States. In August 2021, the Company and Janssen mutually agreed to terminate the Janssen Agreement effective on August 31, 2021.

Pursuant to the Janssen Agreement, as amended, the Company was responsible for the costs associated with its sales force over the course of such co-promotion. Janssen was responsible for all other aspects of the commercialization of SIMPONI® under the Janssen Agreement. In exchange for the Company's sales and co-promotional services, the Company was entitled to a quarterly tiered promotion fee based on the incremental increase in total prescribed units of SIMPONI® for that quarter over a predetermined baseline. For the first and second quarters of 2020, the tiered promotion fee ranged from $750 to $1,250 per prescription over a predetermined baseline. Due in part to COVID-19, in June 2020, the Janssen Agreement was amended to adjust the predetermined average baseline for the third and fourth quarters of 2020. The Janssen Agreement was further amended in June 2020 and December 2020 to adjust the predetermined average baseline for prescribed units for the quarters ending December 31, 2020 and March 31, 2021 and was subject to further adjustment under certain circumstances. In June 2021, the Janssen Agreement was again amended to proportionally increase the baseline for prescribed units for the quarter ended June 30, 2021 to reflect the addition of certain geographies to the sales territories covered by the Janssen Agreement. For the first and second quarters of 2021, the Company was entitled to an amended tiered promotion fee ranging from $500 to $1,000 per prescription based on the incremental increase in total prescribed units, and the Company was entitled to receive a promotion fee of at least $0.3 million, but capped at 10% above the adjusted predetermined baseline.

Upon the termination of the Janssen Agreement on August 31, 2021, the Company became entitled to receive an aggregate of $0.6 million in consideration. Pursuant to the terms of the termination, the Company is restricted from promoting any other biologic or Janus kinase inhibitor used for treatment of indications covered by the Janssen Agreement without first obtaining Janssen's written consent until May 31, 2022.

The Company's obligations relating to sales and co-promotion services for SIMPONI® were a series of single performance obligations since Janssen simultaneously received and consumed benefits provided by the Company's sales and co-promotional services. The method for measuring progress towards satisfying the performance obligations was based on prescribed units in excess of the contractual baseline at the contractual rate earned per unit since the ~~Amended~~ Janssen Agreement, isas amended, was cancelable. The Company recognized no co-promotion revenue ~~of approximately $0.4 million~~ and ~~$1.3~~$0.3 million during the three months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, respectively. The Company recognized no co-promotion revenue ~~of approximately $1.0 million~~ and ~~$3.4~~$0.6 million during the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, respectively. The related expenses for marketing SIMPONI® are included in selling, general and administrative expenses and are expensed as incurred.

Upon the termination of the Janssen Agreement on August 31, 2021, the Company became entitled to receive an aggregate of $0.6 million in consideration, which was earned in the year ended December 31, 2021. Pursuant to the terms of the termination, we were restricted until May 31, 2022 from promoting any other biologic or Janus kinase inhibitor used for the treatment of indications covered by the Janssen Agreement without first obtaining Janssen's written consent. The restriction no longer applies.

Leases

The Company categorizes leases at their commencement as either operating or finance leases. Effective January 1, 2022 upon the adoption of ASC 842, the Company recognizes operating lease ROU assets and operating lease liabilities for each lease arrangement identified. Lease liabilities are recorded at the present value of future lease payments discounted using the Company's incremental borrowing rate for the lease established at the commencement date and ROU assets are measured at the amount of the lease liability plus any initial direct costs, less any lease incentives received before commencement. Lease expense is recognized as a single lease cost over the lease term on a straight-line basis. The Company has elected not to apply the recognition requirements to short-term leases and not to separate non-lease components from lease components for its leases. See Note 5 for details on the Company's leases.

Research and Development

Costs associated with research and development activities are expensed as incurred and include, but are not limited to, personnel-related expenses, including stock-based compensation expense, materials, laboratory supplies, consulting costs, costs associated with setting up and conducting clinical studies and allocated overhead including rent and utilities.

Advertising and Marketing Costs

Costs associated with advertising and marketing activities are expensed as incurred. Total advertising and marketing costs were approximately $0.6 million and ~~$0.3~~$0.4 million for the three months ended ~~September~~June 30, 2022 and 2021, ~~and 2020,~~ respectively, ~~and $1.3 million~~ and $0.9 million and $0.6 million for the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, respectively, and are included in selling, general and administrative expenses in the accompanying condensed statements of operations.

Shipping and Handling Costs

Costs incurred for shipping and handling are included in costs of revenue in the accompanying condensed statements of operations and totaled approximately ~~$0.6~~$0.7 million and ~~$0.4~~$0.6 million for the three months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, respectively, and ~~$1.6~~$1.3 million and ~~$1.1~~$1.0 million for the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, respectively.

Stock-Based Compensation

The Company recognizes compensation expense for all stock-based awards to employees and directors based on the grant-date estimated fair values over the requisite service period of the awards (usually the vesting period) on a straight-line basis. The fair value of stock options and purchases under the Company's 2019 Employee Stock Purchase Plan (ESPP) rights isare determined using the Black-Scholes-Merton (BSM) option pricing model, which requires management to make certain assumptions regarding a number of complex and subjective variables. Equity award forfeitures are recorded as they occur.

The BSM option pricing model incorporates various estimates, including the fair value of the Company's common stock, expected volatility, expected term and risk-free interest rates. The weighted-average expected term of options was calculated using the simplified method. The risk-free interest rate for periods within the contractual term of the option is based on the U.S. Treasury yield in effect at the time of grant. The dividend yield was zero, as the Company has never declared or paid dividends and has no plans to do so in the foreseeable future.

The fair value of each restricted stock unit is determined on the grant date using the closing price of the Company's common stock on the grant date and generally vest from the grant date in 4four equal annual installments subject to the holder's continued service with the Company. The Company issues new shares to satisfy restricted stock units upon vesting.

~~The fair value of the Company's common stock is determined by using the closing price of its common stock on the corresponding date.~~

Comprehensive Loss

Comprehensive loss is defined as a change in equity of a business enterprise during a period, resulting from transactions from nonowner sources. There have been no items qualifying as other comprehensive loss and, therefore, for all periods presented, the Company's comprehensive loss was the same as its reported net loss.

Net Loss Per Share

Basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common

stockholders by the weighted-average number of common stock equivalents outstanding for the period determined using the treasury-stock and if-converted methods. The weighted-average number of shares in 2022 and 2021 used to compute basic and diluted shares includes shares issuable upon the exercise of pre-funded warrants at a nominal price. Potentially dilutive common stock equivalents are comprised of warrants for the purchase of common stock, options, ~~and~~ restricted stock units outstanding under the Company's 2019 Incentive Award Plan (the 2019 Plan) and shares of the Company's common stock pursuant to the ESPP. For the three and ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, there is no difference in the number of shares used to calculate basic and diluted shares outstanding as the inclusion of the potentially dilutive securities would be antidilutive.

Potentially dilutive securities not included in the calculation of diluted net loss per share because to do so would be anti-dilutive are as follows (in common stock equivalent shares):

The Company views its operations as, and manages its business in, 1one operating segment.

Recent Accounting Pronouncements Not Yet Adopted

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (FASB), or other standard setting bodies and adopted by the Company as of the specified effective date. Under the Jumpstart Our Business Startups Act of 2012 (JOBS Act), the Company meets the definition of an emerging growth ~~company.~~company (EGC). The Company has elected to use the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act. Unless otherwise discussed, the impact of recently issued standards that are not yet effective will not have a material impact on the Company's financial position or results of operations upon adoption.

In June 2016, the FASB issued Accounting Standards Update (ASU) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires the measurement of expected credit losses for financial instruments carried at amortized cost, such as accounts receivable, held at the reporting date based on historical experience, current conditions and reasonable forecasts. The main objective of this ASU is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. In November 2018, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financing Instruments-Credit Losses, which included an amendment of the effective date for nonpublic entities. For non-EGCs, ASU 2016-13 is effective for fiscal years beginning after December 15, 2019. For EGCs, the standard was to be effective for fiscal years beginning after December 15, 2021. However, in November 2019, the FASB issued ASU 2019-10, which included a one-year deferral of the effective date of ASU 2016-13 for certain entities. As a result, the ASU 2016-13 is now effective for EGCs for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company is currently evaluating the impact of Topic 326 on its condensed financial statements.

Recently Adopted Accounting Standards

In February 2016, the FASB issued ~~Accounting Standards Update (ASU)~~ASU 2016-02, Leases (Topic 842). The new topic supersedes Topic 840, Leases, and increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and requires disclosures of key information about leasing arrangements. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, which provides narrow

amendments to clarify how to apply certain aspects of the new lease standard, and ASU 2018-11, Leases: Targeted Improvements, which was issued to provide relief to companies from restating comparative periods. Pursuant to this ASU, in the period of adoption the Company will not restate comparative periods presented in its condensed financial statements. The effective date of this guidance for public companies is for reporting periods beginning after December 15, 2018. In June 2020, the FASB issued ASU 2020-05, which delays the adoption of ASU 2016-02 for non-public entities to fiscal years beginning after December 15, 2021, and interim periods beginning after December 15, 2022. As an emerging growth company as defined in the JOBS Act,On January 1, 2022, the Company ~~has elected to early adopt this~~adopted ASU ~~as of January 1, 2022. Topic 842 mandates a~~2016-12 using the modified retrospective transition method. Periods prior to January 1, 2022 have not been restated for the adoption of ASC 842 and continue to reflect the accounting treatment of leases in accordance with the prior lease accounting guidance, ASC 840, Leases. The Company ~~intends to adopt~~adopted the new lease standard using a cumulative effect to accumulated deficit and ~~will elect~~there was no impact to accumulated deficit upon adoption. The Company elected the package of practical expedients, which among other things ~~will allow~~allowed the Company to carry forward its historical lease classification. ~~The Company is currently evaluating the impact~~As part of ~~Topic 842 on its condensed financial statements.~~

~~Recently Adopted Accounting Standards~~

~~In December 2019, the FASB issued ASU 2019-12,~~ ~~Simplifying the Accounting for Income Taxes~~. The new guidance removes certain exceptions to the general principles of ASC 740 in order to simplify the complexities of its application. These changes include eliminations to the exceptions for intraperiod tax allocation, recognizing deferred tax liabilities related to outside basis differences, and year-to-date losses in interim periods, among others. The effective date of this guidance for public companies is for fiscal years, and interim period within those fiscal years, beginning after December 15, 2020. The Company adopted this guidance on January 1, 2021, and the adoption, ~~did not have a material impact~~the Company recorded operating lease liabilities of $6.4 million, operating lease ROU assets of $5.9 million, adjusted for deferred rent and lease incentive obligations of $0.5 million previously included in other non-current liabilities and accrued and other current liabilities, pertaining to its office and laboratory space operating leases.

Note 4. Borrowings

2017 Term Loan

In September 2017, the Company executed a term loan agreement (the 2017 Term Loan) with Innovatus Life Sciences Lending Fund I, LP (Innovatus) and borrowed $20.0 million, $17.8 million of which was immediately used to repay the Company's existing loan with Capital Royalty Partners II L.P. and its affiliates. On December 7, 2018, the Company borrowed an additional $5.0 million under the 2017 Term Loan. ~~At September~~The 2017 Term Loan was subsequently amended in November 2019 and November 2021. As of June 30, ~~2021,~~2022, no additional amounts remain available to borrow under the 2017 Term Loan.

In November ~~2019,~~2021, the Company executed the ~~First~~Second Amendment to the Loan and Security Agreement (the 2017 Loan Amendment). The interest rate on all borrowings under the 2017 Loan Amendment is ~~8.5%~~8.0%, of which 2.0% is paid in-kind in the form of additional term loans (PIK Loans) until December of ~~2022,~~2024, after which interest accrues at an annual rate of ~~8.5%~~8.0%. The Company has estimated the effective interest rate of this loan to be approximately ~~10%~~8.5%. Accrued interest is due and payable monthly, unless the Company elects to pay paid-in-kind interest. The outstanding principal and accrued interest on the 2017 Loan Amendment will be repaid in twenty-four equal monthly installments commencing in December ~~2022.~~2024. Upon repayment of the final installment under the 2017 Loan Amendment, the Company is required to pay an additional fee of $1.0 million. This obligation is being accreted into interest expense over the term of the 2017 Loan Amendment using the effective interest method. For each of the three months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, the Company issued PIK Loans totaling $0.1 million. For each

of the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, the Company issued PIK Loans totaling ~~$0.4~~$0.3 million. ~~In October 2021, the Company executed the Second Amendment to the Loan and Security Agreement (the Second Loan Amendment), discussed in Note 10 to these financial statements, below.~~

The 2017 Loan Amendment requires a prepayment premium of 2%3% of the aggregate outstanding principal. The prepayment premium decreases by 1% on November ~~19, 2021~~1, 2022, 2023 and ~~2022.~~2024.

The 2017 Loan Amendment is collateralized by a first priority security interest in substantially all of the Company's assets, including intellectual property. The affirmative covenants of the 2017 Loan Amendment require that the Company timely file taxes, maintain good standing and government compliance, maintain liability and other insurance, provide prompt notification of significant corporate events, and furnish audited financial statements within 150 days of fiscal year end without qualification as to the scope of the audit or as to going concern and without any other similar qualification.

The affirmative covenants require that the Company achieve a specified level of revenue, as measured quarterly on a rolling twelve-month ~~basis.~~basis, and commencing with the quarter ending December 31, 2022. The consequences of failing to achieve the performance covenant may be cured if, within sixty days of failing to achieve the performance covenant, the Company issues additional equity securities or subordinated debt with net proceeds sufficient to fund any cash flow deficiency generated from operations, as defined. The 2017 Loan Amendment requires that the Company maintain certain levels of minimum liquidity and maintains an unrestricted cash balance of $2.0 million.

The negative covenants provide, among other things, that without the prior consent of Innovatus subject to certain exceptions, the Company may not dispose of certain assets, engage in certain business combinations or acquisitions, incur additional indebtedness or encumber any of the Company's property, pay dividends on the Company's capital stock or make prohibited investments. The 2017 Loan Amendment ~~agreement~~ provides that an event of default will occur if, among other triggers, (i) the Company defaults in the payment of any amount payable under the agreement when due, (ii) there occurs any circumstance(s) that could reasonably be expected to result in a material adverse effect on the Company's business, operations or condition, or on the Company's ability to perform its obligations under the agreement, (iii) the Company becomes insolvent, (iv) the Company undergoes a change in control or (v) the Company breaches any negative covenants or certain affirmative covenants in the agreement or, subject to a cure period, otherwise neglects to perform or observe any material item in the agreement.

~~At September~~As of June 30, ~~2021,~~2022, the Company was in compliance with all covenants of the 2017 Loan Amendment.

Upon an event of default in any of the 2017 Loan Amendment covenants, the repayment of the 2017 Loan Amendment may be accelerated, and the applicable interest rate will be increased by 4.0% until the default is cured. Although repayment of the 2017 Loan Amendment can be accelerated under certain circumstances, the Company believes acceleration of this loan is not probable as of the date of these condensed financial statements. Accordingly, the Company has reflected the amounts of the 2017 Loan Amendment due beyond twelve months of the balance sheet date as non-current.

Note 5. Leases

The Company adopted ASC 842, Leases, as of January 1, 2022. Prior period amounts have not been adjusted and continue to be reported in accordance with the Company's historic accounting under ASC 840, Leases.

Operating Leases

The Company leases office and laboratory spaces in Vista, California, under leases that expire in April 2027, with an option to extend portions of the leases for additional 5-year periods. The Company has not included the optional renewal periods in the measurement of the lease liabilities because it is not reasonably certain that the Company will exercise these renewal options. The Company's lease payments under each of these leases are subject to escalation clauses.

Effective on August 23, 2021, the Company entered into a sub-lease agreement for an additional office space in Carlsbad, California. The sub-lease commenced in October 2021 and expires in April 2027. The sub-lease agreement provides for monthly base rent of $66,021 which began on October 1, 2021, and such amount shall increase by approximately 3% annually beginning October 1, 2022. The Company is entitled to base rent abatement for a specified period of time which began on November 1, 2021.

The Company determines if a contract contains a lease at inception or modification of a contract. The Company discounts their lease obligations using its incremental borrowing rate at the commencement date. The incremental borrowing rate is the rate of interest the Company would have to pay to borrow on a collateralized basis over a similar term and amount equal to the lease payments in a similar economic environment. The Company primarily considers industry data, its credit rating and the lease term to determine its incremental borrowing rate.

Finance Leases

The Company has entered into various finance lease agreements to obtain laboratory equipment. The terms of the Company's finance leases generally range from three to five years and are typically secured by the underlying equipment. The portion of the future payments designated as principal repayments were classified as finance lease liabilities on the Company's balance sheet.

On March 25, 2021, the Company completed a public offering of 4,255,000 shares of its common stock at a public offering price of $16.25 per share. Net proceeds from the offering were approximately $64.7 million, after deducting underwriting discounts, ~~and~~ commissions and other offering expenses of $4.4 million. The shares were registered pursuant to the Company's Shelf Registration Statement discussed above.

Exchange Agreement

On June 22, 2021, the Company entered into an exchange agreement (the Exchange Agreement) with an Investor and its affiliates (the Exchanging Stockholders), pursuant to which the Company exchanged an aggregate of 804,951 shares of the Company's common stock owned by the Exchanging Stockholders for pre-funded warrants (the Exchange Warrants) to purchase an aggregate of 804,951 shares of common stock (subject to adjustment in the event of any stock dividends and splits, reverse stock split, recapitalization, reorganization or similar transaction, as described in the Exchange Warrants), with an exercise price of $0.001 per share. The Exchange Warrants do not expire and are exercisable at any time except that the Exchange Warrants cannot be exercised by the Exchanging Stockholders if, after giving effect thereto, the Exchanging Stockholders would beneficially own more than 4.99% of the Company's common stock, which percentage may change at the Exchanging Stockholder's election to any other percentage upon 61 days' notice to the Company. The Company recorded the retirement of ~~the~~ common stock

exchanged as a reduction of common shares outstanding and additional paid-in-capital at the fair value of the Exchange Warrants on the issuance date. The Exchange Warrants are classified as equity and the fair value of the Exchange Warrants was recorded as an increase to additional paid-in-capital and is not subject to remeasurement. The Company determined that the fair value of the Exchange Warrants is substantially similar to the fair value of the retired shares on the issuance date due to the negligible exercise price for the Exchange Warrants. As of ~~September~~June 30, ~~2021,~~2022, none of the Exchange Warrants have been exercised.

~~Note 9. COVID-19~~

During 2020, due to the worldwide COVID-19 pandemic, the Company experienced a reduction in patient test volumes, delays in patient enrollment in ongoing and planned clinical studies, and delays in the procurement of its testing supplies. In response to the pandemic, the Company has curtailed non-essential employee travel, equipped employees with the ability to work remotely with the exception of clinical laboratory employees, and reduced marketing spend and employee headcount. The full extent to which the COVID-19 pandemic will directly or indirectly continue to impact the Company's business, results of operations and financial condition, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain or treat COVID-19, including, the success of ongoing vaccination efforts, the emergence and prevalence of variant strains of COVID-19, the institution or reinstitution of shutdowns, "stay-at-home-orders" and other public health measures as well as the related economic impact of these matters on local, regional and international markets.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) was enacted in response to the COVID-19 pandemic. The CARES Act, among other things, permits net operating loss (NOL) carryovers and carrybacks to offset 100% of taxable income for taxable years beginning before 2021. The CARES Act did not have a material impact on the Company's effective tax rate or income tax provision for the three months ended March 31, 2020. Under the Tax Cuts and Jobs Act (TCJA), NOLs generated post TCJA were allowed to be carried forward indefinitely but were only allowed to offset 80% of taxable income. As a result of the CARES Act and the change to permit NOLs generated in taxable years 2018, 2019 and 2020 to offset 100% of taxable income, the Company released valuation allowance against its deferred tax assets in the amount of $0.1 million. The release of valuation allowance resulted in a discrete tax benefit of $0.1 million in the first quarter of 2020.

In April 2020, the Company received $0.7 million of funding under the CARES Act Provider Relief Fund, subject to the Company's agreement to comply with the Department of Health & Human Services' standard terms and conditions. The CARES Act Provider Relief Fund is a federal fund allocated for general distributions to Medicare facilities and providers impacted by the COVID-19 pandemic and is intended to support COVID-related expenses or lost revenue attributable to COVID-19. The funding received is considered a government grant, which is recognized when there is reasonable assurance that the grant will be received and that conditions attached to the grant have been met. During the three and nine months ended September 30, 2020, the Company recognized $0 and $0.7 million, respectively, due to lost revenue attributable to COVID-19, which is reflected in other income, net, on its condensed statements of operations.

On April 16, 2020, the Company entered into a promissory note (the Note) with BOKF, NA dba Bank of Oklahoma (BofO), the lender, evidencing an unsecured loan pursuant to the U.S. Small Business Administration (SBA) Paycheck Protection Program (PPP) of the CARES Act of approximately $2.9 million (the PPP Loan). The Company applied for and received the PPP Loan pursuant to the then published PPP qualification and certification requirements. On April 23, 2020, the SBA, in consultation with the Department of Treasury, issued new guidance that created uncertainty regarding the qualification requirements for the PPP Loan (the New Guidance). In light of the New Guidance, on May 11, 2020, the Company paid off in full the principal and interest on the PPP Loan, resulting in the termination of the Note.

On December 27, 2020, the Consolidated Appropriations Act, 2021 was signed into law. It provides additional COVID-19 focused relief and extends certain provisions of the CARES Act. At this time, the Company does not believe that the Consolidated Appropriations Act, 2021 has a material impact on its financial statements.

~~Note 10. Subsequent Events~~

In October 2021, the Company entered into a lease amendment relating to its existing office space located adjacent to the Company's headquarters. The lease amendment extends the term of such lease from January 2026 to April 2027. The lease amendment provides that the base monthly rent for the leased space shall be $22,470 for the 12-month period beginning February 2026 and $23,594 for the period beginning February 2027 through April 2027.

In October 2021, the Company entered into a fifth addendum to the lease relating to its headquarters. The fifth addendum extends to the term of such lease from January 2026 to April 2027. The fifth addendum provides that the base monthly rent for the leased space shall be $20,084 for the period between February 2026 and April 2027.

In October 2021, the Company entered into a first addendum to the lease related to its office and laboratory space in the building attached to the Company's existing headquarters.

The first addendum provides that the base monthly rent for the leased space shall be $14,751 for the period between February 2026 and April 2027.

In October 2021, the Company and Innovatus entered into the Second Loan Amendment to the 2017 Term Loan, which became effective on November 1, 2021. The Second Loan Amendment amends the 2017 Term Loan by, among other things, (i) decreasing the interest rate on all borrowings to 8.0%, of which 2.0% will be paid-in-kind and capitalized to the principal amount of the outstanding term loan on a monthly basis until December 2024; after which interest will accrue at an annual rate of 8.0%; (ii) extending the interest-only period through December 2024 and the maturity date to November 19, 2026; and (iii) changing the specified level of revenue, as measured quarterly on a rolling twelve-month basis, commencing with the quarter ending December 31, 2022, the Company must achieve to satisfy the related financial covenant in the 2017 Loan Amendment, subject to exceptions based on achievement of performance milestones and the ability to cure any default thereof with the issuance of equity securities or subordinated indebtedness.

Overview

We are dedicated to transforming the care continuum for patients suffering from debilitating and chronic autoimmune diseases by enabling timely differential diagnosis and optimizing therapeutic intervention. We have developed and are commercializing a portfolio of innovative testing products under our AVISE® brand, several of which are based on our proprietary ~~CB-CAPs~~Cell-Bound Complement Activation Products (CB-CAPs) technology. Our goal is to enable healthcare providers to improve care for patients through the differential diagnosis, prognosis and monitoring of complex autoimmune and autoimmune-related diseases, including systemic lupus erythematosus ~~or SLE,~~(SLE), and rheumatoid arthritis ~~or RA. Our strategy includes leveraging our portfolio of testing products to market therapeutics through our sales channel, targeting the approximately 5,000 rheumatologists across the United States.~~(RA). Our business model of integrating testing products and therapeutics positions us to offer targeted solutions to rheumatologists and, ultimately, better serve patients.

We currently market 10 testing products under our AVISE® brand that allow for the differential diagnosis, prognosis and monitoring of complex autoimmune and autoimmune-related diseases. Our lead testing product, AVISE® CTD, enables differential diagnosis for patients presenting with symptoms indicative of a wide variety of ~~CTDs~~connective tissue diseases (CTDs), and other related diseases with overlapping symptoms. We commercially launched AVISE® CTD in 2012 and revenue from this product comprised 81% and ~~71%~~81% of our revenue for the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, respectively. There is an unmet need for rheumatologists to add clarity in their CTD clinical evaluation, and we believe there is a significant opportunity for our tests that enable the differential diagnosis of these diseases, particularly for potentially life-threatening diseases such as SLE.

We are leveraging our portfolio of testing products to establish partnerships with leading pharmaceutical companies, academic research centers and patient advocacy organizations. We also have agreements with GlaxoSmithKline plc. (GSK), ~~or GSK, Covance Inc.~~Labcorp Drug Development and Parexel, among others, that leverage our testing products and/or the information generated from such tests. We provide GSK, a leader in lupus therapeutics, our test result data to

provide market insight into and help increase awareness of the benefits of early and accurate diagnosis of SLE and lupus nephritis, and monitoring disease activity. We partner with academic research centers and patient advocacy organizations,

such as Brigham and Women's Hospital, Hospital for Special Surgery, Duke University and Emory University as well as the Lupus Foundation of America, to help improve the quality of life for people affected by autoimmune diseases through programs of research, education, support and advocacy. We plan to pursue additional strategic partnerships that are synergistic with our evolving portfolio of testing products.

We perform all of our AVISE® tests in our approximately 10,000 square foot clinical laboratory, which is certified under the Clinical Laboratory Improvement Amendments of 1988 ~~or CLIA,~~(CLIA), by the Centers for Medicare and Medicaid Services ~~or CMS,~~(CMS), and accredited by the College of American Pathologists ~~or CAP,~~(CAP), and located in Vista, California. Our laboratory is certified for performance of high-complexity testing by CMS in accordance with CLIA and is licensed by all states requiring out-of-state licensure. Our clinical laboratory reports all AVISE® testing product results within five business days. In the second half of 2021, we began the conversion of approximately 8,000 square feet of warehouse space into additional clinical laboratory space and approximately 6,000 square feet of warehouse space into additional research and development facility ~~space, and expect to complete such conversions by the first quarter of 2022 and~~space. In the second quarter of 2022, ~~respectively.~~we completed the clinical laboratory space conversion, which is currently being utilized for both clinical laboratory and research and development purposes. We expect to complete the conversion of the research and development facility space by the second half of 2022. The expansion of our clinical laboratory and research and development facility ~~are~~is expected to allow us to enhance our testing capacity and improve efficiencies as well as allow us to develop molecular and multiomic capabilities and advance our product pipeline, including support of development of tests for fibromyalgia, RA, thrombosis and lupus nephritis.

We market our AVISE® testing products using our specialized sales force. As of ~~September~~June 30, ~~2021,~~2022, we have a sales force of 6257 representatives covering a total of 63 territories. Unlike many diagnostic sales forces that are trained only to understand the comparative benefits of their tests, the specialized backgrounds of our sales force coupled with our comprehensive training ~~enables~~enable our sales representatives to interpret results from our de-identified patient test reports and provide unique insights in a highly tailored discussion with rheumatologists. Our integrated testing and therapeutics strategy results in a unique opportunity to promote and sell targeted therapies in patient focused sales calls with rheumatologists, including those with whom we have a longstanding relationship and history using our portfolio of testing products.

Reimbursement for our testing services comes from several sources, including commercial third-party payors, such as insurance companies and health maintenance organizations, government payors, such as Medicare, and patients. Reimbursement rates vary by product and payor. We continue to focus on expanding coverage among existing contracted rheumatologists and to achieve coverage with commercial payors, laboratory benefit managers and evidence review organizations.

Since inception we have devoted substantially all of our efforts to developing and marketing products for the diagnosis, prognosis and monitoring of autoimmune diseases. Although our revenue has historically increased sequentially year over year, with the exception of the six months ended June 30, 2022 compared to 2021, we have never been profitable and, as of ~~September~~June 30, ~~2021~~2022, we had an accumulated deficit of ~~$201.1~~$233.1 million. We incurred net losses of ~~$19.8~~$24.9 million and ~~$13.2~~$12.6 million for the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, respectively. We expect to continue to incur operating losses in the near term as our operating expenses will increase to support the growth of our business, as well as additional costs associated with being a public company. We have funded our operations primarily through equity and debt financings and revenue from sales of our products. We completed our initial public offering ~~or IPO,~~(IPO), in September 2019, raising net proceeds from the offering of approximately $50.4 million, net of underwriting discounts, commissions and other offering expenses, for aggregate expenses of approximately $7.5 million. In March 2021, we completed a public offering of 4,255,000 shares of our common stock at a public offering price of $16.25 per share. Net proceeds from the offering were approximately $64.7 million, net of underwriting discounts and commissions and offering costs of $4.4 million. As of ~~September~~June 30, ~~2021,~~2022, we had ~~$106.8~~$76.4 million of cash and cash equivalents.

Recent Developments

In ~~October 2021,~~March 2022, we entered into an agreement with ~~Inland Empire Health Plan, or IEHP,~~Centene Corporation, pursuant to ~~offer~~which, effective June 1, 2022, AVISE® ~~CTD and AVISE~~® ~~Lupus tests on~~test offerings became an in-network, ~~basis~~covered benefit with Centene Corporation, including its subsidiary WellCare Health Plans, providing enhanced care to ~~approximately~~ over ~~one~~22.7 million ~~IEHP~~ members.

~~Impact of COVID-19~~

The current COVID-19 worldwide pandemic has presented substantial public health challenges and is affecting our employees, patients, physicians and other healthcare providers, communities and business operations, as well as the U.S. and global economies and financial markets. International and U.S. governmental authorities in impacted regions have taken actions in an effort to slow the spread of COVID-19, including issuing varying forms of "stay-at-home" orders, restricting business functions outside of one's home, restricting gatherings, restricting travel, and

As a result, of COVID-19 related limitations and reordering of priorities across the U.S. healthcare system, a reduction in patient flow occurred and our test volumes began to decrease in the second half of March 2020 and we experienced an AVISE® ~~CTD volume decrease of approximately 5% in~~tests will surpass 99 million lives as an in-network benefit for patients.

A pricing determination is not synonymous with a coverage determination. Having a price associated with the PLA code for any particular test does not secure coverage or reimbursement for that PLA code from Medicare or any other third-party payor.

During the quarter, we submitted to ~~pre-COVID-19 levels. For~~Noridian 3,749 claims for Medicare Part B reimbursement under our PLA code for AVISE® Lupus. As of August 1, 2022, 76 of these claims have been paid, 335 claims have been denied, 2,778 claims are subject to requests from Noridian for additional information (such as medical records), and the ~~three months ended September 30, 2021~~balance of those claims remain pending with no responses received as ~~compared~~of this date.

While we are still gathering information from Noridian, we believe these denials and requests for additional information may be due in part to confusion regarding appropriate American Medical Association (AMA) Common Procedural Terminology (CPT) coding for the ~~same period in 2020, we experienced an~~ AVISE® CTD test, ~~volume increase of approximately 21%.

For example, we have experienced delays in patient enrollment for ongoing and planned clinical studies involving our tests, which may delay or prevent launch of future test products. We have also experienced delays in procurement of our testing supplies due in part to suppliers rationing testing supplies and prioritizing COVID-19 testing beginning in the first quarter of 2021, which may continue into the future, and our partners may also experience a disruption in their ability to readily obtain supply. Our sales force has been, and for an extended period of time may continue to be limited, in their in-person interactions with healthcare providers, and therefore, also limited in their ability to engage in various types of healthcare provider education activities. Healthcare providers and patients have canceled or delayed scheduling, and for an extended period of time may continue to cancel or delay scheduling, standard wellness visits and other non-emergency appointments and procedures, contributing to a decline in orders of our testing products. The portion of our workforce which has been working remotely in an effort to reduce the spread of COVID-19, may be infected from the virus or otherwise distracted. We may also face increased competition for laboratory and scientific employees due to the increased demand in the industry for such personnel. We may inaccurately estimate the duration or severity of the COVID-19 pandemic, which could cause us to misalign our staffing, spending, activities and precautionary measures with market current or future market conditions.

In response to the COVID-19 pandemic, we initially curtailed non-essential travel and have equipped most of our employees with the ability to work remotely with the exception of our clinical laboratory employees, and implemented measures to protect the health of our employees and to support the functionality of our clinical laboratory, such as providing personal protective equipment (including face masks or shields) and maintaining social distancing.

Recent Publications

In July 2022, we announced new, real-world evidence illustrating that AVISE® testing enables decisive clinical action in the differential diagnosis of lupus. The "Complement Activation Products vs Standard ANA Testing: Treatment Outcomes, Diagnosis, and Economic Impact in Systemic Lupus Erythematosus," (CAPSTONE) study was the largest comparative utility study in lupus diagnostics and was published in the Journal of Managed Care & Specialty Pharmacy. The study leveraged multiple databases encompassing electronic health records and linked insurance claims data on nearly 50,000 patients tested with AVISE® or standard of care labs from hundreds of rheumatologists across the United States, comparing diagnosis, treatment, and cost of care outcomes for new patients tested with AVISE® Lupus and those tested with a traditional ANA (tANA) approach, including specific autoantibodies. The CAPSTONE study supports that the AVISE® Lupus test is more clinically effective, both for patients who test positive and those who test negative, as compared to the current standard of care. Important key findings of the CAPSTONE study included, among other things, a: (i) 2x decrease in diagnostic testing costs in the first six-month follow-up period for AVISE® Lupus [-] vs tANA[-]; (ii) 3.5x less frequent repeat testing overall when using AVISE® Lupus vs. tANA; (iii) 6x increased odds of establishing a new SLE diagnosis with AVISE® Lupus [+] vs tANA[+]; and (iv) 3x increased odds of initiating one or more SLE treatments with AVISE® Lupus [+] vs tANA[+]. The CAPSTONE study exemplifies the advantages of the AVISE® Lupus test for patients, providers, and payors. Delayed diagnosis leads to increased disease burden and diminished quality of life for the patient relative to the current standard of care. By receiving conclusive results, providers are able to initiate treatment early, reducing the need for more

aggressive approaches down the road that can lead to irreversible consequences for the patient. Additionally, a conclusive negative test allows providers to lower the number of repeat tests and follow-up visits which ~~included three employees at~~is a critical step for achieving diagnostic clarity for the ~~vice president level.~~ patient.

Impact of COVID-19

The full extent of which the COVID-19 pandemic will directly or indirectly continue to impact our business, results of operations and financial condition and will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain it or treat COVID-19, including the success of ongoing vaccination efforts, the emergence and prevalence of variant strains of COVID-19, the institution or reinstitution of shutdowns, "stay-at-home-orders" and other public health measures, as well as the related economic impact of these matters on local, regional and international markets.

We have implemented business continuity plans designed to address the COVID-19 pandemic and minimize disruptions to ongoing operations. While for the three months ended June 30, 2022 as compared to the same period in 2021, we experienced an AVISE® CTD test volume increase of approximately 5%, and for the six months ended June 30, 2022 as compared to the same period in 2021, we experienced an AVISE® CTD test volume increase of approximately 6%, the patient flow and our related test volumes have in the past been, and may continue to be, impacted by the COVID-19 pandemic. We have experienced, and may again, experience significant impacts on our test volume, delays in patient enrollment for ongoing and planned clinical trials, and delays in procurement of our testing supplies as a result of the COVID-19 pandemic.

In addition, COVID-19 travel limitations and government-mandated work-from-home or shelter-in-place orders have, and may again, cause supply chain delays or reduce the number of in-person meetings between our sales force and healthcare providers and limit the ability of our sales force to engage in various types of healthcare provider education activities, which may lead to a decline in orders of our testing products. To mitigate the impact of COVID-19 on our business, we put in place certain safety measures for our employees, patients, healthcare providers, and suppliers to limit exposure and a portion of our workforce was required to work remotely in an effort to reduce that spread of COVID-19.

We are facing and may continue to face increased competition for laboratory and scientific employees due to the increased demand in the industry for such personnel. As the circumstances surrounding the COVID-19 pandemic remain uncertain, we may inaccurately estimate the duration or severity of the COVID-19 pandemic, which could, among other things, cause us to misalign our staffing, spending, activities and precautionary measures with market current or future market conditions.

Factors Affecting Our Performance

In addition to the impact of COVID-19, we believe there are several important factors that have impacted, and that we expect will impact, our operating performance and results of operations, including:

▪Continued Adoption of Our Testing Products. Since the launch of AVISE® CTD in 2012 and through ~~September~~June 30, ~~2021,~~2022, we have delivered over ~~581,000~~680,000 of these tests. Through the ~~third~~second quarter of ~~2021, 94,099~~2022, 65,822 AVISE® CTD tests were delivered, representing approximately ~~31%~~6% growth over the same period in ~~2020.~~2021. The number of ordering healthcare providers in the ~~third~~second quarter of ~~2021~~2022 was a record ~~1,969,~~2,273, representing an approximate 18% increase over the same period in ~~2020,~~2021, and we had a record ~~714~~797 adopting healthcare providers (defined as those who previously prescribed at least 11 diagnostic tests in the corresponding period) compared to ~~600~~703 in the same period in ~~2020.~~2021. A high percentage of adopting healthcare providers continue to order tests in subsequent quarters, as approximately 99% of adopting healthcare providers from the ~~second~~first quarter of ~~2021~~2022 ordered at least one diagnostic test in the ~~third~~second quarter of ~~2021.~~2022. Revenue growth for our testing products will depend on our ability to continue to expand our base of ordering healthcare providers and increase our penetration with existing healthcare providers.

▪Reimbursement for Our Testing Products. Our revenue depends on achieving broad coverage and reimbursement for our tests from third-party payors, including both commercial and government payors such as Medicare. Payment from third-party payors differs depending on whether we have entered into a contract with the payors as a "participating provider" or do not have a contract and are considered a "non-participating provider." Payors will often reimburse non-participating providers, if at all, at a lower amount than participating providers. We have received a substantial portion of our revenue from a limited number of

third-party commercial payors, most of which have not contracted with us to be a participating provider. ~~Historically,~~In addition to the challenges described under the heading "Overview - Recent Developments" above, historically, we have experienced situations where commercial payors proactively reduced the amounts they were willing to reimburse for our tests, and in other situations, commercial payors have determined that the amounts they previously paid were too high and have sought to recover those perceived excess payments by deducting such amounts from payments otherwise being made. When we contract to serve as a participating provider, reimbursements are made pursuant to a negotiated fee schedule and are limited to only covered indications. If we are not able to obtain or maintain coverage and adequate reimbursement from third-party payors, we may not be able to effectively increase our testing volume and revenue as expected. Additionally, retrospective reimbursement adjustments can negatively impact our revenue and cause our financial results to fluctuate.

▪~~Success of~~ Synergistic Partnerships. In August 2021, we mutually agreed to terminate the Janssen Agreement regarding our promotion efforts with SIMPONI®, effective August 31, 2021. Our SIMPONI® promotion efforts contributed no co-promotion revenue and approximately ~~$1.0 million and $3.4~~$0.6 million in revenue ~~for~~during the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, respectively. We will continue to rely on our existing testing products to drive revenue growth and intend to leverage our integrated testing and therapeutics strategy to establish partnerships with a focus on the development and commercialization of therapeutics that are synergistic with our testing products.growth.

▪Development of Additional Testing Products. We rely on sales of our AVISE® CTD test to generate the significant majority of our revenue. We expect to continue to invest in research and development in order to develop additional testing products and expect these costs to increase. Our success in developing new testing products will be important in our efforts to grow our business by expanding the potential market for our testing products and diversifying our sources of revenue.

▪Maintain Meaningful Margin. We believe we are well positioned to maintain meaningful margin through a continued focus on increasing operating leverage through the implementation of certain internal initiatives, such as conducting additional validation and reimbursement oriented clinical studies to facilitate payor coverage of our testing products, capitalizing on our growing reagent purchasing to negotiate improved volume-based pricing and automation in our clinical laboratory to reduce material and labor costs.

▪Timing of Our Research and Development Expenses. Our spending on experiments and clinical studies may vary substantially from quarter to quarter. We also expend funds to secure clinical samples that can be used in discovery, product development, clinical validation, utility and outcome studies. The timing of these research and development activities is difficult to predict. If a substantial number of clinical samples are obtained in a given quarter or if a high-cost experiment is conducted in one quarter versus the next, the timing of these expenses will affect our financial results. We conduct clinical studies to validate our new testing products, as well as ongoing clinical and outcome studies to further expand the published evidence to support our commercialized AVISE® testing products. Spending on research and development for both experiments and studies may vary significantly by quarter depending on the timing of these various expenses.

▪How We Recognize Revenue. We record revenue on an accrual basis based on our estimate of the amount that will be ultimately realized for each test upon delivery based on a historical analysis of amounts collected by test and by ~~payor.~~a payor and other factors. Variable consideration for the open AVISE® Lupus Medicare claims is deemed to be fully constrained due to the uncertainty of the outcome of these claims. For fully constrained claims, we generally recognize revenue in the period the uncertainty is definitively resolved and we can provide no assurance that such resolution will be achieved on a timely basis, or at all. Changes to such estimates may increase or decrease revenue recognized in future periods.

While each of these areas ~~present~~presents significant opportunities for us, they also pose significant risks and challenges that we must address. We discuss many of these risks, uncertainties and other factors in the section entitled "Risk Factors."

Janssen Promotion Agreement

In December 2018, we entered into the Janssen Agreement, under which we ~~are~~were responsible for the costs associated with our sales force in promoting SIMPONI® in the United States. In August 2021, ~~the Company~~we and Janssen mutually agreed to terminate the Janssen Agreement effective on August 31, 2021. Pursuant to the Janssen Agreement, as amended, Janssen was responsible for all other costs associated with our promotion of SIMPONI® under the Janssen Agreement. In exchange for our sales and co-promotional services, we were entitled to a quarterly tiered promotion fee based on the incremental increase in total prescribed units of SIMPONI® for that

quarter over a predetermined baseline. For the quarter ended September 30, 2020, the tiered promotion fee ranged from $750 to $1,250 per prescription over a predetermined baseline. Due in part to COVID-19, in June 2020 we amended the Janssen Agreement, to adjust the predetermined average baseline for the third and fourth quarters of 2020. In December 2020, we further amended the Janssen Agreement, to adjust the average baseline for total prescribed units of SIMPONI® for the quarters ending December 31, 2020 and March 31, 2021, subject to further adjustment under certain circumstances. In June 2021, the Janssen Agreement was again amended to proportionally increase the baseline for prescribed units for the quarter ending June 30, 2021 to reflect the addition of certain geographies to the sales territories covered by the Janssen Agreement. For the first and second quarters of 2021, we were entitled to an amended quarterly tiered promotion fee ranging from $500 to $1,000 per prescription based on the incremental increase in total prescribed units of SIMPONI® ~~for that quarter over the predetermined baseline, and we were entitled to receive a minimum promotion fee of $0.3 million and the fee was be capped at 10% above the adjusted predetermined baseline.~~ Upon ~~the~~ termination of the Janssen Agreement on August 31, 2021, we became entitled to receive an aggregate of $0.6 million in ~~consideration.~~consideration, which was earned in the year ended December 31, 2021. Pursuant to the terms of the termination, we ~~are~~were restricted until May 31, 2022 from promoting any other biologic or Janus kinase inhibitor used for the treatment of indications covered by the Janssen Agreement without first obtaining Janssen's written ~~consent until May 31, 2022.~~consent. The restriction no longer applies.

We recognized no revenue and approximately ~~$1.0 million and $3.4~~$0.6 million in revenue ~~for~~during the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, respectively, for our promotional efforts under the Janssen Agreement.

Seasonality

Based on our experience to date, we expect some seasonal variations in our financial results due to a variety of factors, such as the year-end holiday period and other major holidays, vacation patterns of both patients and healthcare providers, including medical conferences, climate and weather conditions in our markets (for example excess sun exposure can cause flares in SLE), seasonal conditions that may affect medical practices and provider activity, including for example influenza outbreaks that may reduce the percentage of patients that can be seen, and other factors relating to the timing of patient benefit changes, as well as patient deductibles and co-insurance limits.

Financial Overview

Revenue

To date, we have derived nearly all of our revenue from the sale of our testing products, most of which is attributable to our AVISE® CTD test. We primarily market our testing products to rheumatologists in the United States. The rheumatologists who order our testing products and to whom results are reported are generally not responsible for payment for these products. The parties that pay for these services, or payors, consist of healthcare insurers, government payors (primarily Medicare and Medicaid), client payors (e.g. hospitals, other laboratories, etc.), and patient self-pay. Our service is completed upon the delivery of test results to the prescribing rheumatologists which triggers billing for the service.

We recognize revenue in accordance with the provisions of ASC Topic 606, Revenue from Contracts with Customers. We record revenue on an accrual basis based on our estimate of the amount that will be ultimately realized for each test upon delivery based on a historical analysis of amounts collected by test and by ~~payor.~~payor and other factors. These assessments require significant judgment by management.

As more fully described under the heading "Overview - Recent Developments" above, we experienced a disruption in our revenue recognition and cash collection during the quarter ended June 30, 2022 in relation to Medicare Part B reimbursements for our AVISE® Lupus test. Variable consideration for the open AVISE® Lupus Medicare claims is deemed to be fully constrained due to the uncertainty of the outcome of these claims. For fully constrained claims, we generally recognize revenue in the period the uncertainty is definitively resolved and we can provide no assurance that such resolution will be achieved on a timely basis, or at all.

Our ability to increase our revenue will depend on our ability to further penetrate the market for our current and future testing products, and increase our reimbursement and collection rates for tests delivered.

As discussed above, our volume of AVISE® CTD tests delivered substantially recovered to pre-COVID-19 levels in the fourth quarter of 2020. However, the continued spread of COVID-19, including any of its viral variants, may adversely affect testing volumes in future periods, and the extent of any such adverse effects is highly uncertain.

Operating Expenses

Costs of Revenue

Costs of revenue represents the expenses associated with obtaining and testing patient specimens. The components of our costs of revenue include materials costs, direct labor, equipment and infrastructure expenses associated with testing specimens, shipping charges to transport specimens, blood specimen collections fees, royalties, depreciation and allocated overhead, including rent and utilities.

Each payor, whether a commercial third-party, government, or individual, reimburses us at different amounts. These differences can be significant. As a result, our costs of revenue as a percentage of revenue may vary significantly from period to period due to the composition of payors for each period's billings.

Assuming future testing volumes are not negatively impacted by the continued spread of COVID-19, we expect that our costs of revenue will increase in absolute dollars as the number of tests we perform increases. However, we expect that the cost per test will decrease over time due to volume discounts on materials and ~~shipping costs and~~ other volume efficiencies we may gain as the number of tests we perform increases. The decrease in cost per test may be partially offset due to increased depreciation and allocated overhead associated with our clinical laboratory expansion as well as increased labor, material and shipping costs (including as a result of inflation) associated with the commercialization of our portfolio products. As discussed above, the continued spread of COVID-19 may adversely affect testing volumes which may result in an increase in cost per test due to our inability to realize volume efficiencies.

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist of personnel costs, including stock-based compensation expense, direct marketing expenses, accounting and legal expenses, consulting costs, and allocated overhead including rent, information technology, depreciation and utilities.

We expect that our selling, general and administrative expenses will increase in absolute dollars in ~~2021~~2022 as compared to ~~2020, as we continue~~2021, due to ~~evaluate the reach and frequency of our sales and sales support functions,~~ expected additions to headcount and associated increases for personnel costs, including stock-based compensation.

Research and Development Expenses

Research and development expenses include costs incurred to develop our technology, ~~testing~~test products and product candidates, collect clinical specimens and conduct clinical studies to develop and support our testing products and product candidates. These costs consist of personnel costs, including stock-based compensation expense, materials, laboratory supplies, consulting costs, costs associated with setting up and conducting clinical studies and allocated overhead including rent and utilities. We expense all research and development costs in the periods in which they are incurred.

We expect that our research and development expenses will increase in absolute dollars in ~~2021~~2022 as compared to ~~2020,~~2021, as we continue to invest in research and development activities related to our existing testing products and product candidates, including the expansion of our clinical research and development facility, expected additions to headcount and associated increases for personnel costs, including stock-based compensation.

Interest Expense

Interest expense consists of cash and non-cash interest expense associated with our financing arrangements, including the borrowings under our amended loan and security agreement with Innovatus Life Sciences Lending Fund I, LP ~~or Innovatus.~~(Innovatus).

We expect interest expense to remain substantially consistent in ~~2021 as compared to 2020, and remain consistent thereafter until 2023.~~the near term.

Other Income (Expense), Net

Other income (expense), net, consists primarily of interest income earned on our cash and cash ~~equivalents and amount received under the CARES Act Provider Relief Fund in the second quarter of 2020.~~

~~Income Tax Benefit~~

~~Income taxes include federal and state income taxes in the United States.~~equivalents.

Costs of Revenue

Costs of revenue increased ~~$1.1~~$0.6 million, or ~~26.4%~~11.5%, for the three months ended ~~September~~June 30, ~~2021~~2022 compared to the three months ended ~~September~~June 30, ~~2020.~~2021. This increase was primarily due to increased direct costs such as labor, materials and supplies, ~~labor and~~ shipping and handling and allocated overhead associated with the increase in test volume in ~~2021~~2022 compared to ~~2020.~~2021. Gross margin as a percentage of revenue decreased to 20.1% for the three months ended June 30, 2022, compared to 57.3% for the three months ended June 30, 2021. This was primarily attributable to a decrease in average reimbursement per AVISE® CTD test and a decrease in revenue resulting from the Janssen Agreement.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased ~~$2.3~~$1.7 million, or ~~25.3%~~15.5%, for the three months ended ~~September~~June 30, ~~2021~~2022 compared to the three months ended ~~September~~June 30, ~~2020.~~2021. This increase was primarily due to an increase of ~~$1.9~~$0.8 million of employee related expenses, including stock-based compensation and recruitment expenses, ~~and~~ increases related to ~~marketing expenses of $0.3 million,~~ audit and professional services of ~~$0.1~~$0.2 million, legal fees of $0.2 million, marketing expenses of $0.2 million, allocated overhead of $0.2 million and insurance expenses of $0.1 million.

Research and Development Expenses

Revenue

Revenue decreased $5.4 million, or 22.9%, for the six months ended June 30, 2022 compared to the six months ended June 30, 2021, primarily due a decrease in AVISE® CTD revenue of $4.4 million.

~~Revenue~~

~~Revenue increased $6.3 million, or 21.5%, for the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020, primarily due to an increase in the number~~outcome of ~~diagnostic tests delivered resulting in part from volume reductions experienced in late March 2020 as a result of the COVID-19 pandemic.~~certain claims, which have been deemed fully constrained. The number of AVISE® CTD tests delivered, which accounted for 81% ~~and 71%~~ of revenue in each of the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, respectively, increased to ~~94,099~~65,822 tests delivered in the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 compared to ~~71,849~~62,357 tests delivered in the same ~~2020~~2021 period. The ~~adoption~~number of ~~the AVISE~~® ~~CTD test by healthcare providers for the nine months ended September 30, 2021 increased to 2,595~~ ordering healthcare providers asincreased to 2,273 for the three months ended June 30, 2022 compared to ~~2,273 ordering healthcare providers~~1,934 in the same ~~2020~~2021 period. ~~The increase in revenue was partially offset by a decrease in revenue~~Revenue resulting from the Janssen Agreement ~~during~~contributed no revenue for the ~~nine~~six months ended ~~September~~June 30, ~~2021 to approximately $1.0 million~~2022 compared to ~~approximately $3.4~~$0.6 million during the ~~nine~~six months ended ~~September~~June 30, ~~2020.~~2021.

Costs of Revenue

Costs of revenue increased ~~$3.4~~$1.7 million, or ~~28.0%~~17.1%, for the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 compared to the ~~nine~~six months ended ~~September~~June 30, ~~2020.~~2021. This increase was primarily due to increased direct costs such as materials and supplies, labor, ~~and~~ shipping and handling and allocated overhead associated with the increase in test volume and increase in ~~2021~~cost per test in 2022 compared to ~~2020, partially offset by~~2021. Gross margin as a percentage of revenue decreased ~~royalty costs.~~to 33.9% for the six months ended June 30, 2022, compared to 56.5% for the six months ended June 30, 2021. This was primarily attributable to a decrease in average reimbursement per AVISE® CTD test, an increase in cost per test, and a decrease in revenue resulting from the Janssen Agreement.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased ~~$5.6~~$3.8 million, or ~~20.8%~~18.1%, for the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 compared to the ~~nine~~six months ended ~~September~~June 30, ~~2020.~~2021. This increase was primarily due to an increase of ~~$4.4~~$2.4 million of employee related expenses, including stock-based compensation and recruitment expenses, ~~and~~ increases related to ~~insurance expenses~~allocated overhead of $0.4 million, ~~marketing expenses~~legal fees of ~~$0.3~~$0.4 million, ~~and~~ audit and professional services of $0.2 ~~million. The first quarter~~million, marketing expenses of ~~2020 included one-time restructuring charges~~$0.2 million and insurance expenses of ~~approximately $0.2~~$0.1 million.

Research and Development Expenses

Research and development expenses increased ~~$2.6~~$1.5 million, or 45.5%, for the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 compared to the ~~nine~~six months ended ~~September~~June 30, ~~2020.~~2021. This increase was primarily due to increases in expenses related to ~~clinical trial expenses of $0.9 million, employee related expenses,~~current, former and potential employees, including severance, stock-based compensation and recruitment expenses of ~~$0.9~~$1.2 million, ~~license fees~~collaboration expenses of ~~$0.4~~$0.5 million, allocated overhead of $0.3 million, laboratory supplies expense of ~~$0.2~~$0.3 million and ~~collaboration~~consulting fees of $0.1 million, partially offset by decreases in clinical trial expenses of ~~$0.2~~$0.4 million and license fees of $0.4 million.

Interest Expense

Interest expense remained substantially consistent for the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 compared to the ~~nine~~six months ended ~~September~~June 30, ~~2020.~~2021.

Other Income (Expense), Net

Other income (expense), net, ~~decreased $1.0 million~~remained substantially consistent for the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 compared to the ~~nine~~six months ended ~~September~~June 30, 2020. The decrease was primarily driven by the $0.7 million we received under the CARES Act Provider Relief Fund due to lost revenues attributable to COVID-19 in the second quarter of 2020 and lower money market interest rates in 2021 compared to 2020.

~~Income Tax Benefit~~

Income tax benefit decreased $0.1 million for the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020 due to a change in tax law under the CARES Act enacted in 2020 that resulted in an income tax benefit during the nine months ended September 30, 2020.2021.

Liquidity and Capital Resources

We have incurred net losses since our inception. For the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, we incurred a net loss of ~~$19.8~~$24.9 million and ~~$13.2~~$12.6 million, respectively, and we expect to incur additional losses and increased operating expenses in future periods. As of ~~September~~June 30, ~~2021,~~2022, we had an accumulated deficit of ~~$201.1~~$233.1 million. To date, we have generated only limited revenue, and we may never achieve revenue sufficient to offset our expenses.

~~Through the date~~Our primary sources of ~~our IPO in September 2019, our operations were financed primarily from~~capital have been sales of our common stock and redeemable convertible preferred stock, the sale of our common stock in our IPO, and, to a lesser extent, borrowings under various debt financings. In September 2019, we completed our IPO and received net proceeds of approximately $50.4 million, net of underwriting discounts, commissions and other offering expenses, for aggregate expenses of approximately $7.5 million. On November 10, 2020, we filed a registration statement on Form S-3 or(Shelf Registration Statement), which was declared effective by the ~~Shelf Registration Statement,~~SEC on November 19, 2020, covering the offering, from time to time, of up to $150.0 million of common stock, preferred stock, debt securities, warrants and ~~units, which Shelf Registration Statement became effective on November 19, 2020.~~units. In March 2021, we completed a public offering of 4,255,000 shares of our common stock at a public offering price of $16.25 per share,

which shares were sold under the Shelf Registration Statement. Net proceeds from the offering were approximately $64.7 million, net of underwriting discounts and commissions and other offering expenses of $4.4 million. As of ~~September~~June 30, ~~2021,~~2022, we had ~~$106.8~~$76.4 million of cash and cash equivalents. Cash in excess of immediate requirements is invested in accordance with our investment policy, primarily with a view to liquidity and capital preservation. Currently, our funds are held in cash and money market funds.

In September 2017, we entered into the loan and security agreement with Innovatus under which we immediately drew down $20.0 million. In December 2018, we borrowed an additional $5.0 million under the loan agreement. In each of November 2019 and November 2021, we amended the loan and security agreement with Innovatus, which we collectively refer to as the Amended Loan Agreement. Pursuant to the Amended Loan Agreement, the loan term is for nine years with a final maturity date of November 2026. The Amended Loan Agreement accrues interest at an annual rate of 8.0%, of which 2.0% will be payable in-kind. Paid in-kind interest is added to the principal balance each period. After December 1, 2024, the entire 8.0% will be paid in cash at the end of each period. On or after November 1, 2022, we may, at our option, prepay the term loan borrowings by paying the lender a prepayment premium. The prepayment premium was 3% as of November 2021 and decreases by 1% on each of November 1, 2022, November 1, 2023 and November 1, 2024.

Our obligations under the Amended Loan Agreement are secured by a security interest in substantially all of our assets, including our intellectual property. The Amended Loan Agreement contains customary conditions to borrowing, events of default, and covenants, including covenants requiring us to maintain certain levels of minimum

liquidity of $2.0 million, performance covenants to achieve certain minimum amounts of revenue, and covenants limiting our ability to dispose of assets, undergo a change in control, merge with or acquire other entities, incur debt, incur liens, pay dividends or other distributions to holders of our capital stock, repurchase stock and make investments, in each case subject to certain exceptions. The consequences of failing to achieve the performance covenant will be cured if, within sixty days of failing to achieve the performance covenant, we issue additional equity securities or subordinated debt with net proceeds sufficient to fund any cash flow deficiency generated from operations, as defined in the Amended Loan Agreement. ~~At September~~As of June 30, ~~2021,~~2022, we were in compliance with all covenants of the Amended Loan Agreement. In addition, upon the occurrence of an event of default, Innovatus, among other things, can declare all indebtedness due and payable immediately, which would adversely impact our liquidity and reduce the availability of our cash flows to fund working capital needs, capital expenditures and other general corporate purposes.

In connection with the execution of the loan and security agreement with Innovatus in November 2017, we issued the lender a seven-year warrant to purchase 15,384,615 shares of our Series F redeemable convertible preferred stock at an exercise price of $0.078 per share, and in December 2018, in connection with the additional $5.0 million borrowed under the loan and security agreement, we issued to the lender a seven-year warrant to purchase 3,846,154 shares of our Series F redeemable convertible preferred stock at an exercise price of $0.078 per share. In connection with the completion of our IPO in September 2019, the warrants were automatically converted into warrants exercisable for an aggregate of 104,722 shares of common stock at an exercise price of $14.32 per share.

In April 2020, we received $0.7 million of funding under the CARES Act Provider Relief Fund, subject to our agreement to comply with the Department of Health & Human Services', or HHS, standard terms and conditions. The CARES Act Provider Relief Fund is a federal fund allocated for general distributions to Medicare facilities and providers impacted by the COVID-19 pandemic and is intended to support healthcare-related expenses or lost revenue attributable to COVID-19.

Funding Requirements

Our primary uses of cash are to fund our operations as we continue to grow our business. We expect to continue to incur operating losses in the near term as our operating expenses will be increased to support the growth of our business. We expect that our costs of revenue, selling, general and administrative expenses, and research and development expenses will continue to increase as we increase our test volume, expand our marketing efforts and increase our internal sales force to drive increased adoption of and reimbursement for our AVISE® testing products, prepare to commercialize new testing products, continue our research and development efforts and further develop our product pipeline. We believe we have sufficient laboratory capacity to support increased test volume. We expect to make significant investments for laboratory equipment and capital expenditures in the near term related to our laboratory facilities and expansion of research capabilities, including an investment to convert approximately 8,000 square feet of warehouse space into additional clinical laboratory space and approximately 6,000 square feet of warehouse space into additional research and development facility space. We began such conversion in the second

half of 2021 and ~~expect to complete~~completed the conversion for the clinical laboratory space byin the ~~first~~second quarter of 2022 and expect to complete the conversion for the additional research and development facility byin the second ~~quarter~~half of 2022. The converted clinical laboratory space is currently being utilized for both clinical laboratory and research and development purposes. The expansion of our clinical laboratory and research and development facility are expected to allow us to enhance our testing capacity and improve efficiencies as well as allow us to develop molecular and multiomic capabilities and advance our product pipeline, including support of the development of tests for fibromyalgia, RA, thrombosis and lupus nephritis. Cash used to fund operating expenses is impacted by the timing of when we pay expenses, as reflected in the change in our outstanding accounts payable and accrued expenses.

We expect that our near- and longer-term liquidity requirements will continue to consist of working capital and general corporate expenses associated with the growth of our business, including payments we may be required to make upon the achievement of previously negotiated milestones associated with intellectual property we have licensed, payments related to non-cancelable purchase obligations with one supplier for reagents, payments related to our principal and interest under our long term borrowing arrangements, payments for operating leases related to our office and laboratory space in Vista, California and our office space in Carlsbad, California, and payments for ~~capital~~finance leases related to our laboratory equipment. Based on our current business plan, we believe that our existing cash and cash equivalents and our anticipated future revenue, will be sufficient to meet our anticipated cash requirements for at least the next 12 months from the date of this filing.

Our estimate of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement and involves risks and uncertainties, and actual results could vary as a result of a number of factors, including:

•the impact of the COVID-19 pandemic on our ~~business, including challenges resulting from social distancing and stay-at home orders through a reduction in testing volumes;~~business;

•our ability to maintain and grow sales of our AVISE® testing products, as well as the costs associated with conducting clinical studies to demonstrate the utility of our products and support reimbursement efforts;

•our ability to achieve sufficient market acceptance, coverage and adequate reimbursement from third-party payors and adequate market share and revenue for our testing products;

•fluctuations in working capital;

•the costs of developing our product pipeline, including the costs associated with conducting our ongoing and future validation, utility and outcome studies as well as the success of our development efforts;

•the additional costs we may incur as a result of operating as a public company;

•the extent to which we establish additional partnerships or in-license, acquire or invest in complementary businesses or products as well as the success of our existing partnerships and/or in-licenses; and

•the costs associated with our promotion of other therapeutics, if any, including the expansion of our sales capabilities, and the extent and timing of generating revenue from each such ~~promotion.~~promotion, if any.

Until such time, if ever, as we can generate revenue to support our costs structure, we expect to finance our operations through equity offerings, debt financings or other capital sources, including potentially collaborations, licenses and other similar arrangements. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our stockholders may be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. If additional funding is required or desired, there can be no assurance that additional funds will be available to us on acceptable terms on a timely basis, if at all, or that we will generate sufficient cash from operations to adequately fund our operating needs or achieve or sustain profitability. If we are unable to raise additional capital or generate sufficient cash from operations to adequately fund our operations, we will need to delay, reduce or eliminate some or all of our research and development programs, product portfolio expansion plans or commercialization efforts. Doing so will likely have an unfavorable effect on our ability to execute on our business plan and could have a negative impact on our ~~relationships with parties such as our~~ commercial and strategic relationships. If we cannot expand our operations or otherwise capitalize on our business opportunities because we lack sufficient capital, our business, financial condition, and results of operations could be adversely affected.

Critical Accounting Policies and Significant Management Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our condensed financial statements, which have been prepared in accordance with United States generally accepted accounting principles ~~or U.S. GAAP.~~(GAAP). The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by ~~U.S.~~ GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported revenue generated and expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions, and any such differences may be material.

For a description of our critical accounting policies, please see the section entitled "Management's Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies and Significant Management

Estimates" contained in our Annual Report on Form 10-K for the year ended December 31, ~~2020,~~2021. Except as ~~amended. There~~disclosed in Note 2 to the unaudited condensed financial statements included in this Amended Quarterly Report on Form 10-Q/A, there have been no significant changes in our critical accounting policies and estimates during the three months ended ~~September~~June 30, ~~2021~~2022 as compared to the critical accounting policies and estimates disclosed in the Management’s Discussion and Analysis of Financial Condition and Operations included in our Annual Report on Form 10-K for the year ended December 31, ~~2020, as amended, other than as set forth in Note 2 to~~2021 filed with the ~~unaudited condensed financial statements included in this Quarterly Report~~SEC on ~~Form 10-Q.~~March 22, 2022.

Recent Accounting Pronouncements

Please see Note 2 to the unaudited condensed financial statements included in this Amended Quarterly Report on Form ~~10-Q~~10-Q/A for a summary of changes in significant accounting policies.

~~Off-Balance Sheet Arrangements~~

During the periods presented we did not have, nor do we currently have any off-balance sheet arrangements, as defined under the rules and regulations of the Securities and Exchange Commission, or the SEC.

JOBS Act Accounting Election

The Jumpstart Our Business Startups Act of 2012 ~~or the~~(the JOBS ~~Act,~~Act), contains provisions that, among other things, reduce certain reporting requirements for an "emerging growth company." The JOBS Act permits an "emerging growth company" such as us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We have elected to use this extended transition period under the JOBS Act until the earlier of the date we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our audited financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

We will remain an emerging growth company until the last day of our fiscal year following the fifth anniversary of the date of the first sale of our common equity securities pursuant to an effective registration statement under the Securities Act of 1933, as amended ~~or the~~(the Securities ~~Act,~~Act), which ~~such fifth anniversary~~ will occur in 2024. However, if certain events occur prior to the end of ~~such~~this five-year period, including if we become a "large accelerated filer" as defined in Rule 12b-2 under the Exchange Act, our annual gross revenues exceed $1.07 billion or we issue more than $1.0 billion of non-convertible debt in any three-year period, we ~~may~~will cease to be an emerging growth company prior to ~~the end of such five-year period.~~this anniversary.

Item 3. Quantitative and Qualitative Disclosures ~~about~~About Market Risk

Not applicable.

Item 4. Controls and Procedures

~~Evaluation~~At the end of ~~Disclosure Controls~~the period covered by this Amended Quarterly Report on Form 10-Q/A, our management, with the participation of our principal executive officer and ~~Procedures~~

~~We maintain~~principal financial officer, evaluated the effectiveness of our disclosure controls and procedures. Disclosure controls and procedures ~~that are~~include, without limitation, controls and procedures designed to ensure that information required to be disclosed in ~~the~~our reports that we file ~~with~~ or submit tounder the ~~SEC~~Exchange Act is recorded, processed, summarized and reported within the time ~~periods~~period specified in the SEC’s rules and forms, and that the information required to be disclosed by us in such ~~information~~reports is accumulated and communicated to our management, including our principal executive officer and principal financial officer or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management ~~recognized~~recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable and not absolute assurance of achieving the desired control objectives. In reaching a reasonable level of assurance, management necessarily ~~was~~is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. In addition, the design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, control may become inadequate because of changes in conditions, or the degree of

compliance with policies or procedures may deteriorate.

On November 13, 2022, management and the audit committee of our board of directors determined that we made certain errors in revenue resulting from erroneous and duplicate billings related to changes in billing practices. The errors were due to the inadequate design and implementation and precision of internal controls and procedures to evaluate and monitor the accounting for revenue recognition. As a result, revenue and accounts receivable were overstated and other liabilities was understated for the quarter and year to date periods ended June 30, 2022.

We have concluded that these were material errors in the financial statements requiring a restatement of the Form 10-Q for the three and six months ended June 30, 2022.

Accordingly, management has determined that this control deficiency constituted a material weakness and, as a result, management has concluded that, as of June 30, 2022, our internal control over financial reporting was not effective based on the criteria in Internal Control Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria).

Based on that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were not effective to ensure that the information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Remediation Plan to Address the Material Weaknesses

Management is actively engaged in the planning for, and implementation of, remediation efforts to address the material weakness. The remediation plan includes: (i) evaluating the staffing level, skills and qualification of accounting department personnel, (ii) enhancement of our existing control structure and processes for revenue recognition and (iii) improving the detailed review process of our revenue recognition models. The elements of our remediation plan can only be accomplished over time, and we can offer no assurance that these initiatives will ultimately have the intended effects.

The elements of our remediation plan can only be accomplished over time, and we can offer no assurance that these initiatives will ultimately have the intended effects. The weakness will not be considered remediated, however, until the applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively.

Changes in Internal Control Over Financial Reporting

Other than the material weakness and remediation plan discussed above, there were no changes in our internal control over financial reporting (as such term is defined by Rules 13a-15(f) and 15d-15(f) of the Exchange Act)

during the most recent fiscal quarter ended June 30, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls and Procedures

Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Our management, with the participation of our principal executive officer and our principal financial officer, evaluated, as of the end of the period covered by this quarterly report, the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on that evaluation, our principal executive officer and principal financial officer have concluded that as of September 30, 2021, our disclosure controls and procedures were effective at the reasonable assurance level. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and our management necessarily applies its ~~judgement~~judgment in evaluating the cost-benefit relationship of possible controls and procedures.

~~Changes in Internal Control Over Financial Reporting~~

There have been no changes in our internal control over financial reporting during the three months ended September 30, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Part II. Other Information

Item 1. Legal Proceedings

We are currently not a party to any material legal proceedings. From time to time, we may be involved in legal proceedings or subject to claims incident to the ordinary course of business. Regardless of the outcome, such proceedings or claims can have an adverse impact on us because of defense and settlement costs, diversion of resources and other factors, and there can be no assurances that favorable outcomes will be obtained.

Item 1A. Risk Factors

There have been no material changes to the risk factors disclosed in Part I, Item 1A, "Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, ~~2020,~~2021, other than those set forth below:

We have identified a material weakness in our internal control over financial reporting and determined that our disclosure controls and procedures were ineffective as of June 30, 2022, in connection with the restatement of our financial statements as of and for the three and six months ended June 30, 2022. In the future, we may identify additional material weaknesses or otherwise fail to maintain an effective system of internal control over financial reporting or adequate disclosure controls and procedures, which may result in material errors in our financial statements or cause us to fail to meet our period reporting obligations.

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our reports that we file or submit under the Securities and Exchange Act of 1934, as amended, ~~other than~~is recorded, processed, summarized and reported within the time period specified in the SEC’s rules and forms, and that the information required to be disclosed by us in such reports is accumulated and communicated to our management, including our principal executive officer and principal financial officer or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable and not absolute assurance of achieving the desired control objectives. In reaching a reasonable level of assurance, management necessarily is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. In addition, the design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, control may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate.

On November 13, 2022, management and the audit committee of our board of directors determined that we made certain errors in revenue resulting from erroneous and duplicate billings related to changes in billing practices. The errors were due to the ~~risk factors set forth below:~~inadequate design and implementation and precision of internal controls and procedures to evaluate and monitor the accounting for revenue recognition. As a result, revenue and accounts receivable were overstated and other liabilities was understated for the quarter and year to date periods ended June 30, 2022.

We then determined that there were material errors in the financial statements requiring a restatement of the Form 10-Q for the three and six months ended June 30, 2022.

remediation plan can only be accomplished over time, and we can offer no assurance that these initiatives will ultimately have the intended effects.

If we are not able to comply with the applicable requirements of the Sarbanes-Oxley Act of 2002 or if we are unable to maintain effective internal control over financial reporting, we may not be able to produce timely and accurate financial statements or guarantee that information required to be disclosed by us in the reports that we file with the SEC, is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms. Any failure of our internal control over financial reporting or disclosure controls and procedures could cause our investors to lose confidence in our publicly reported information, cause the market price of our stock to decline, expose us to sanctions or investigations by the SEC or other regulatory authorities, or impact our results of operations.

Risks Related to Our Business and Strategy

~~Our business is subject to risks arising from epidemic diseases, such as the continuing global pandemic of the COVID-19 coronavirus.~~

~~The current COVID-19 worldwide pandemic has presented substantial public health challenges~~If third-party payors do not provide coverage and ~~is affecting~~adequate reimbursement for our employees, patients, physicians and other healthcare providers, communities and business operations, as well as the U.S. and global economies and financial markets. International and U.S. governmental authorities in impacted regions have taken actions in an effort to slow the spread of COVID-19, including issuing varying forms of "stay-at-home" orders, restricting business functions outside of one's home, restricting gatherings, restricting travel, and mandating social distancing and face coverings. While many jurisdictions have fully reopenedtesting products, or ~~have begun a phased re-opening, the potential to return to prior restrictions remains~~they breach, rescind or modify their contracts or reimbursement policies or delay payments for our tests, or if there are future increases (or, in some jurisdictions, continued increases) in new cases of COVID-19 or any of its viral variants, including the Delta variant. The duration of any restrictions may also vary depending on the ultimate success of ongoing vaccination efforts. Even in areas where "stay-at-home" restrictions, masking and social distancing measures have been lifted and the number of COVID-19 cases have declined, some jurisdictions are considering re-imposing these measures as variant strains emerge. Many individuals remain cautious about resuming activities such as preventative-care medical visits. A pandemic, including COVID-19 or other public health epidemic, poses the risk that we or our ~~employees, contractors, suppliers, third-party shipping carriers, government~~partners are unable to successfully negotiate payor contracts, our revenues, gross margins and commercial success could be materially adversely affected.

Successful commercialization of our tests depends, in large part, on the availability of coverage and adequate reimbursement from third-party payors, including government payors, such as Medicare and ~~other members~~Medicaid, and private insurers. For the tests that we develop and commercialize, each third-party payor decides whether to cover the test, the amount it will reimburse for a test and the specific conditions for reimbursement.

Reimbursement by third-party payors may depend on a number of factors, including the payor’s determination that tests using our technologies are:

•not experimental or investigational;

•medically necessary;

•demonstrated to lead to improved patient outcomes;

•appropriate for the specific patient;

•cost-saving or cost-effective;

•supported by peer-reviewed medical journals; and

•included in clinical guidelines.

If we are unable to provide third-party payors with sufficient evidence of the clinical utility and validity of our ~~supply chain~~tests, they may ~~be prevented from conducting business activities for an indefinite period of time, including due to spread of the disease within these groups~~not provide coverage, or ~~due to shutdowns that~~ may be requested or mandated by governmental authorities. As a result of COVID-19 related limitations and reordering of priorities across the U.S. healthcare system, a reduction in patient flow occurred and our test volumes began to decrease in the second half of March 2020 and we experienced an AVISE® ~~CTD volume decrease of approximately 5% in the year ended December 31, 2020 as compared to 2019. In the fourth quarter 2020, our volume of AVISE~~® ~~CTD tests delivered substantially recovered to pre-COVID-19 levels. For the three months ended September 30, 2021 as compared to the same period in 2020, we experienced an AVISE~~® ~~CTD volume increase of approximately 21%. For the nine months ended September 30, 2021 as compared to the same period in 2020, we experienced an AVISE~~® ~~CTD test volume increase of approximately 31%. However, the continued spread of COVID-19 and patient hesitancy in seeking preventative medical care, the extent of~~provide limited coverage, which ~~are dependent on circumstances that are highly uncertain, may~~will adversely affect testing volumes in future periods. Healthcare providers and patients have canceled or delayed scheduling, and for an extended period of time may continue to cancel or delay scheduling, standard wellness visits and other non-emergency appointments and procedures, contributing to a decline in orders of our ~~testing products. The economic downturn may also result in closures of the practices of our primary customers.~~

In addition, we believe there are several other important factors that have impacted, and that we expect will impact our operating performance and results of operations, including shutdowns of our facilities and operations as well as those of our suppliers and courier services, disruptions to the supply chain of material needed for our tests, our sales and commercialization activitiesrevenue and our ability to ~~receive specimens~~succeed. In addition, clinicians may be less likely to order a test unless a third-party payor pays a substantial portion of the test price. Therefore, coverage determinations and ~~perform or deliver~~reimbursement levels and conditions are critical to commercial success, and if we are not able to secure positive coverage determinations and reimbursement levels, our business will be materially adversely affected. Moreover, the ~~results from our tests, delays~~COVID-19 pandemic may cause a delay in ~~reimbursement and~~ coverage decisions from Medicare and third-party payors, and in interactions with regulatory authorities, as well as our inability to achieve or re-negotiate volume-based discounts with our key suppliers and to absorb fixed laboratory expenses. For example, we have experienced delays in patient enrollment forhas delayed ongoing and planned clinical ~~studies~~trials involving our tests, the occurrence of which may ~~delay~~ have a material adverse effect on our business.

Third-party payors and other entities also conduct technology assessments of new medical tests and devices and provide and/or ~~prevent launch~~sell the results of ~~future test products. Our sales force has been,~~their assessments to other parties. These assessments may be used by third-party payors and ~~for an extended period of time may continue to be, limited to their in-person interactions with~~ healthcare providers as grounds to deny coverage for or refuse to use a test or procedure. In addition, third-party payors have increased their efforts to control the cost, utilization and ~~therefore, also limited their ability to engage in various types~~delivery of healthcare ~~provider education activities. The portion of our workforce which~~services. These measures have resulted in reduced payment rates and decreased utilization for the diagnostics industry.

Effective April 25, 2012, Palmetto GBA, the Medicare molecular diagnostic services program contractor, or MolDX Program, assigned the AVISE® MTX assay a unique identifier and determined that the test meets the applicable Medicare coverage criteria to support dose optimization and therapeutic decision making for patients diagnosed with RA on methotrexate. Our current Medicare Administrative Contractor, Noridian Healthcare Solutions, LLC, or Noridian, has been working remotely in an effort to reduce the spread of COVID-19, may be infected from the virus or otherwise impaired. We have also experienced delays in procurement of our testing supplies due in part to suppliers rationing testing supplies and prioritizing COVID-19 testing beginning in the first quarter of 2021, which may continue into the future, and our partners, may also experience a disruption in their ability to readily obtain supply. We may also face increased competition for laboratory and scientific employees due to the increased demand in the industry for such personnel. We may inaccurately estimate the duration or severity of the COVID-19 pandemic, which could cause us to misalign our staffing, spending, activities and precautionary measures with market current or future market conditions.adopted this coverage policy.

~~Our laboratory operations, including laboratory employees~~We experienced a disruption in our revenue recognition and ~~medical directors,~~cash collection during the quarter ended June 30, 2022 in relation to Medicare Part B reimbursements for our AVISE® Lupus test and may experience future disruptions in this revenue and cash collection. Effective April 1, 2022 CMS recognized a new PLA code for our protein-based test, AVISE® Lupus, and Noridian priced this PLA code at $1,085 per test. The process for establishing reimbursement for new tests can be uncertain, lengthy and time consuming. A pricing determination is not synonymous with a coverage determination.Having a price associated with the PLA code for any particular test does not secure coverage or reimbursement for that PLA code from Medicare or any other third-party payor.

Beginning April 1 2022, we billed Noridian for AVISE® Lupus under its new PLA code. However, to date, we have received few payments, with the substantial majority of these claims either resulting in requests for additional information and denials from Noridian. In order to confirm coverage and payment of claims, we submitted a formal request to Noridian for coverage of our AVISE® Lupus test. This request may not be successful, and we may ultimately be required to pursue additional strategies for reimbursement with Noridian, which may include seeking a local coverage determination or a local coverage article. These alternative strategies may not be successful and, even if successful, may be ~~subject~~time-consuming, resource intensive and require multiple quarterly or annual periods to ~~closure~~complete. During the pendency of these efforts, we may be unable to collect reimbursement from Noridian for all or ~~shut down, either~~some of our AVISE® Lupus claims, which could again result in a disruption in recognizing related revenue for billed AVISE® Lupus claims. If our efforts to seek reimbursement are ultimately unsuccessful, we may not receive any revenue or cash from these claims.

Other third-party payors make their own decisions as to whether to establish a policy to reimburse for our tests. Because approvals must be sought on a payor-by-payor basis, establishing broad coverage is a time-consuming and costly process. There are many third-party payors who have not yet established a coverage policy applicable to our tests. In addition, several Blue Cross Blue Shield plans and Aetna issued non-coverage policies with respect to AVISE® Lupus, determining that AVISE® Lupus does not meet the medical criteria for coverage and is considered investigational and/or experimental.

While our tests are reimbursed by a number of third-party payors, we do not currently have contracts with significant private payors. We have in the past, and will likely in the future, experience delays and temporary interruptions in the receipt of payments from third-party payors due to ~~the spread of the disease within~~changes in their internal processes, documentation requirements and other issues, which could cause our revenue and cash to fluctuate from period to period.

If we are not successful in reversing existing non-coverage policies, obtaining and maintaining consistent reimbursement for billed tests or if other third-party payors issue negative coverage policies, these ~~individuals, or as part of a larger scale government recommendation or mandate. Disruptions in our laboratory operations~~policies could have a material adverse effect on our business and operations. Even if many third-party payors currently reimburse for our testing products, such payors may withdraw coverage at any time, review and adjust the rate of reimbursement, require co-payments from patients or stop paying for our tests altogether, any of which would reduce our revenue.

Risks Related to Regulatory and Compliance Matters

We conduct business in a heavily regulated industry. Complying with the numerous statutes and regulations pertaining to our business is expensive and time-consuming, and any failure by us, our consultants or commercial partners to comply could ~~impede~~result in substantial penalties.

Our industry and our operations are heavily regulated by various federal, state, local and foreign laws and regulations, and the regulatory environment in which we operate could change significantly and adversely in the future. These laws and regulations currently include, among others:

•CLIA’s and CAP’s regulation of our laboratory activities;

•FDA laws and regulations, including but not limited to requirements for offering LDTs;

•federal and state laws and standards affecting reimbursement by government payors, including certain coding requirements to obtain reimbursement and certain changes to the payment mechanism for clinical laboratory services resulting from the Protecting Access to Medicare Act of 2014, or PAMA;

•HIPAA and HITECH, which establish comprehensive federal standards with respect to the privacy and security of PHI, and requirements for the use of certain standardized electronic transactions with respect to transmission of such information, as well as similar laws protecting other types of personal information;

•state laws governing the maintenance of personally identifiable information of state residents, including medical information, and which impose varying breach notification requirements, some of which allow private rights of action by individuals for violations and also impose penalties for such violations;

•the federal Anti-Kickback Statute, which generally prohibits knowingly and willfully offering, paying, soliciting or receiving remuneration, directly or indirectly, in return for or to induce a person to refer to an individual any good, facility, item or service that is reimbursable under a federal healthcare program;

•the federal Stark Law, which generally prohibits a physician from making a referral for certain designated health services covered by the Medicare program, including laboratory and pathology services, if the physician or an immediate family member has a financial relationship with the entity providing the designated health services;

•the federal False Claims Act, which imposes civil penalties, and provides for civil whistleblower or qui tam actions, against individuals or entities for knowingly presenting, or causing to be presented, to the federal government, claims for payment that are false or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay money to the federal government;

•the federal Civil Monetary Penalties Law, which generally prohibits, among other things, the offering or transfer of remuneration to a Medicare or Medicaid beneficiary if it is likely to influence the beneficiary’s selection of a particular provider, practitioner or supplier of services reimbursable by Medicare or Medicaid;

•EKRA, which imposes criminal penalties for knowing or willful payment or offer, or solicitation or receipt, of any remuneration, whether directly or indirectly, overtly or covertly, in cash or in kind, in exchange for the referral or inducement of laboratory testing (among other healthcare services) covered by healthcare benefit programs (including commercial insurers) unless a specific exception applies;

•the ACA, which, among other things, establishes a requirement for providers and suppliers to report and return any overpayments received from the Medicare and Medicaid programs;

•other federal and state fraud and abuse laws, such as anti-kickback laws, prohibitions on self-referral, fee-splitting restrictions, insurance fraud laws, anti-markup laws, prohibitions on the provision of tests at no or discounted cost to induce physician or patient adoption and false claims acts, some of which may extend to services reimbursable by any third-party payor, including private payors;

•the prohibition on reassignment of Medicare claims and other Medicare and Medicaid billing and coverage requirements;

•state laws that prohibit other specified healthcare practices, such as billing physicians for tests that they order, waiving coinsurance, copayments, deductibles and other amounts owed by patients, business corporations practicing medicine or employing or engaging physicians to practice medicine and billing a state Medicaid program at a price that is higher than what is charged to one or more other payors;

•the FCPA, and applicable foreign anti-bribery laws;

•federal, state and local regulations relating to the handling and disposal of regulated medical waste, hazardous waste and biohazardous waste and workplace safety for healthcare employees;

•laws and regulations relating to health and safety, labor and employment, public reporting, taxation and other areas applicable to businesses generally, all of which are subject to change, including, for example, the significant changes to the taxation of business entities were enacted in December 2017; and

•similar foreign laws and regulations that apply to us in the countries in which we operate or may operate in the future.

Any future growth of our business, including, in particular, continued reliance on consultants, commercial partners and other third parties, may increase the potential for violating these laws. In some cases, our risk of violating these or other laws and regulations is further increased because of the lack of their complete interpretation by applicable regulatory authorities or courts, and their provisions are thus open to a variety of interpretations.

We have adopted policies and procedures designed to comply with these laws and regulations, and, in the ordinary course of our business, we conduct internal reviews of our compliance with these laws. Our compliance is also

subject to review by applicable government agencies. However, these laws and regulations are subject to change and additional interpretation and guidance from regulatory authorities. For instance, in April 2022, the Department of Health and Human Services Office of Inspector General issued a new advisory opinion indicating that a particular clinical laboratory’s practice of contracting with hospitals for the collection of samples for testing could, based on the facts provided and assuming the requisite intent, be a violation of the federal Anti-Kickback Statute. If this Advisory Opinion ultimately limits our ability to ~~process tests~~collect samples in a ~~timely manner,~~hospital setting, we may be required to contract for sample collection with other collection sites or ~~at all.~~sources, such as mobile phlebotomists, that could be more expensive and less convenient for patients, which could adversely affect both demand for our tests and the margins and profitability of our tests.

~~The occurrence~~Given the complexity of these existing and changing rules and regulations, it is not always possible to identify and deter misconduct by employees, distributors, consultants and commercial partners and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from government investigations or other actions or lawsuits stemming from a failure to comply with applicable laws or regulations. Additionally, we are subject to the risk that a person or government could allege such fraud or other misconduct, even if none occurred. Any action brought against us for violation of these or other laws or regulations, even if we successfully defend against it, could cause us to incur significant legal expenses, divert our management’s attention from the operation of our business and harm our reputation. If our operations, including the conduct of our employees, consultants and commercial partners, are found to be in violation of any of these laws and regulations, we may be subject to applicable penalties associated with the ~~foregoing events~~violation, including administrative, civil and criminal penalties, damages, fines, individual imprisonment, exclusion from participation in federal healthcare programs, refunding of payments received by us and curtailment or cessation of our operations. Any of these consequences could seriously harm our business and our financial results.

It is possible that some of our business activities could be subject to challenge under one or more of such laws. Such a challenge, regardless of the outcome, could have a material adverse effect on our business, business relationships, reputation, financial condition and results of operations. ~~The COVID-19 pandemic~~Although an effective compliance program can mitigate the risk of investigation and mitigation measures have had and may continue to have an adverse impact on global economic conditions which could have an adverse effect on our business and financial condition, including impairing our ability to raise capital on a timely basis or at all. The extent to whichprosecution for violations of these laws, the ~~COVID-19 pandemic impacts our results will depend on future developments that are highly uncertain and~~risks cannot be ~~predicted, including new information that~~entirely eliminated. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. Moreover, achieving and sustaining compliance with these laws may ~~emerge concerning the severity~~prove costly. If we or our operations, or any of the ~~virus and the actions~~rheumatologists or entities with whom we do business are found to ~~contain its impact. COVID-19 may also have the effect~~be in violation of ~~heightening many~~any of the laws described above or any other ~~risks described in this section and in the "Risk Factors" section of our Annual Report on Form 10-K for the year ended December 31, 2020, as amended.~~

~~Developing new testing products involves a lengthy and complex process, and we may not be able~~governmental regulations that apply to ~~commercialize on a timely basis, or at all, other testing products we are developing.~~

We will continue to devote considerable resources to the research and development of our planned future testing products and enhancements to our current testing products. We may not be able to develop testing products with the clinical utility necessary to be useful and commercially successful. There are certain products for which a commercial launch would trigger additional payment obligations to licensors of the technology. In these cases, if the economic projections of the product do not outweigh the additional obligations, we may not launch these products. In order to develop and commercialize testing products, we need to:

•~~expend significant funds to conduct substantial research and development;~~

•~~conduct successful validation studies;~~

•~~develop and scale our laboratory processes to accommodate different tests;~~

•~~achieve and maintain required regulatory certifications, including the hiring of appropriately licensed laboratory personnel;~~

•~~develop and scale our infrastructure to be able to analyze increasingly large amounts of data; and~~

•~~build the commercial infrastructure to market and sell new testing products.~~

~~Our testing product development process involves a high degree of risk and may take several years. Our testing product development efforts may fail for many reasons, including:~~

•~~failure to identify additional biomarkers to incorporate into our testing products;~~

•~~failure or sub-optimal performance of the testing product at the research or development stage;~~

•~~obtaining patient consent inclusive of genetic analysis;~~

•~~difficulty in accessing archival patient blood specimens, especially specimens with known clinical results; or~~

•~~failure of clinical validation, utility and outcome studies to support the effectiveness of the test.~~

Typically, few research and development projects result in commercial products, and success in early clinical studies often is not replicated in later studies. At any point, we may abandon development of a testing product candidate orus, we may be ~~required~~subject to ~~expend considerable resources repeating clinical studies, which would adversely affect the timing for generating potential revenue~~significant penalties, including administrative, civil and/or criminal penalties, damages, fines, disgorgement, individual imprisonment, exclusion from ~~a new testing product~~participation in U.S. federal or state healthcare programs, such as Medicare and ~~our ability to invest in other products in our pipeline.~~

In the second half of 2021, we began the conversion of approximately 8,000 square feet of warehouse space into additional clinical laboratory space and approximately 6,000 square feet of warehouse space into additional research and development facility space in order to develop molecular and multiomic capabilities. We have not yet developed any molecular or multiomic testing products nor do we have experience developing and integrating molecular biomarkers into new or existing testing products, and we may never be successful doing soMedicaid in the ~~future. As~~U.S. and similar programs outside the U.S., a ~~result, there is considerable risk that~~corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws, and the ~~expansion~~curtailment or restructuring of our ~~clinical laboratory and research and development facility may not lead to the development~~operations, any of additional testing products that generate meaningful revenue. Further, as we begin to expand our clinical laboratory and research and development facility in order to develop molecular and multiomic capabilities, we expect to need to make significant investments in key personnel and highly trained scientists with relevant experience to handle the increased operations and development of molecular biomarkers.

In addition, as we develop testing products, we will have to make significant investments in product development, marketing and selling resources. If a clinical validation study fails to demonstrate the prospectively defined endpoints of the study, we might choose to abandon the development of the testing product or product feature that

~~was the subject of the clinical study,~~ which could ~~harm our business. Additionally, competitors may develop and commercialize competing products or technologies faster than us or at a lower cost.~~

Developing new testing products and enhancements to our existing technologies is expensive and time consuming, and there is no assurance that such activities will result in significant new marketable testing products, enhancements to our current technologies, design improvements, cost savings, revenue or other expected benefits. If we spend significant resources on research and development and are unable to generate an adequate return on our investment or divert resources away from other, more attractive growth opportunities, our business and results of operations may be materially ~~and adversely affected.~~

Our future growth depends, in part, on our ability to execute on our strategy of integrating the promotion of our existing and future proprietary testing products with the promotion of therapeutics through third party collaborations and strategic partnerships, and we may be unsuccessful in our efforts to establish relationships with these third parties or our promotion efforts after any of these relationships are established, which could adversely affect our ability to ~~implement this strategy.~~

~~We intend to integrate~~operate our ~~historical testing products~~ business ~~with~~and our financial results. To the promotion of therapeutics in an integrated testing and therapeutics strategy. Our integrated testing and therapeutics strategy would leverage our sales and marketing efforts, targeting rheumatologists for the commercializationextent that any of our testing products are sold in ~~co-promotion with therapeutics. As~~ a result, our future growth is dependent, in part, on the success of this strategy. The Janssen Agreement was terminated effective as of August 31, 2021. While we remain committed to the strategy of providing an integrated testing and therapeutics model,foreign country, we may be ~~unsuccessful in our efforts~~subject to ~~establish relationships with collaborators in the future. Even if we successfully establish these relationships, our ability~~similar foreign laws and regulations, which may include, for instance, applicable post-marketing requirements, including safety surveillance, anti-fraud and abuse laws, and implementation of corporate compliance programs and reporting of payments or transfers of value to effectively implement this strategy will include creating demand for the applicable therapeutic through our or our collaborator's commercial and sales activities. Moreover, we may encounter difficulties in maintaining an effective salesforce in furtherance of these co-promotion efforts. We have a limited history partnering with pharmaceutical companies for the promotion of therapeutics. Consequently, any predictions made about our future success or viability with respect to our promotion activities may not be as accurate as they could be if we had a history of successfully co-promoting therapeutics.

If we fail to successfully establish and maintain relationships with these collaborators and strategic partners, our ability to implement our integrated testing and therapeutics strategy and generate sufficient revenue to grow and sustain our business, and our business, financial condition and results of operations, will be materially adversely affected.healthcare professionals.

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

Use of Proceeds

On September 18, 2019, the SEC declared effective our registration statement on Form S-1 (File No. 333-233446), as amended, filed in connection with our IPO. At the closing of the offering on September 23, 2019, we issued and sold 4,140,000 shares of our common stock at the initial public offering price to the public of $14.00 per share, which included the exercise in full of the underwriters’ option to purchase additional shares. We received gross proceeds from the IPO of $58.0 million, before deducting underwriting discounts, commissions and other offering expenses, which resulted in net proceeds of approximately $50.4 million and offering-related transaction costs of approximately $7.5 million. Cowen and Company, LLC, Cantor Fitzgerald & CoCo. and William Blair & Company, L.L.C. acted as joint book-running managers for the offering. No offering expenses were paid or are payable, directly or indirectly, to our directors or officers, to persons owning 10% or more of any class of our equity securities or to any of our affiliates.

As of ~~September~~June 30, ~~2021,~~2022, we have used ~~approximately $32.2 million~~all of the proceeds from our IPO primarily related to selling and marketing activities. There has been no material change in the planned use of such proceeds from that described in the final prospectus filed by us with the SEC on September 20, 2019.

Recent Sales of Unregistered Securities

Between September 1, 2021 and September 30, 2021, we issued 17,719 shares of common stock pursuant to the exercise of common stock warrants. These warrants had an exercise price of $1.84 per share and were exercised for an aggregate exercise price of $32,538.

These issuances were made in reliance on Section 4(a)(2) of the Securities Act. The recipients of the shares represented their intention to acquire the securities for investment only and not with a view to, or for sale in connection with, any distribution thereof, and appropriate legends were affixed to the securities.
